Peptic ulcers may be prevented and cured by well-chewed food rich in vegetable fibers and fermented milk products, which increase protective salivary mucus and decrease damaging bile flow.

The research conducted a review of epidemiologic studies focusing on the variations of diet and eating patterns related to the prevalence of peptic ulcer disease across various communities. The effects of dietary patterns were assessed on saliva, gastric juice, and bile. The role of bile was specifically examined in the pathogenesis of peptic ulcer, with the argument that it, rather than hydrochloric acid, played a causal role. The role of saliva in preventing peptic ulcers was emphasized, particularly the protective nature of salivary mucus which is swallowed with food.

The study then suggested the types of diets that can help prevent peptic ulcers, including those rich in roughage, cellulose, vegetable fibers, and fermented milk products such as ghee and yogurt. The research posited this kind of diet can increase the amount of salivary mucus and consequently decrease the flow rate of harmful bile. The study also noted that these insights showed minor changes in diet, and a slower pace of consumption could lead to substantial health benefits.

Moving from dietary composition to eating behaviors, it was suggested that food should be well-masticated to ensure these beneficial digestive processes have an opportunity to occur. At the same time, the research made the case that specific dietary components, particularly short-chain fatty acids like those found in milk products, can retard gall bladder contraction, thereby reducing the amount of bile entering the duodenal lumen. This secondary action further contributes to the potential prevention of peptic ulcers.

Carrageenan, a common food additive, potentially exacerbates Inflammatory Bowel Disease (IBD) symptoms by altering gut microbiota, inducing intestinal permeability, and triggering inflammation.

The study involved a comprehensive literature review, where the researchers carried out an in-depth analysis of past studies evaluating carrageenan's impact on gut health, particularly in relation to Inflammatory Bowel Disease (IBD). Using predefined search terms, they scoured medical and scientific databases, MEDLINE and SCOPUS. They considered research focusing on carrageenan's effect on the gut microbiota, intestinal permeability, inflammatory processes, its relationship with cancer, and its role as a food additive in the context of autoimmune diseases.

The review divulged that degraded carrageenan, as used in animal studies, appeared to promote intestinal ulceration and inflammation, suggesting a potential risk in exacerbating IBD. Additionally, carrageenan also appeared to disrupt gut microbiota, reducing bacterial diversity therein, and increased intestinal permeability, which in turn could possibly contribute to 'leaky gut' syndrome. Interestingly, some studies suggested a possible anti-cancer effect, since carrageenan might inhibit the growth of cancer cells by affecting cell cycle progression. Besides, the additive seemed to elevate glucose intolerance and insulin resistance.

Chinese herbal medicines could potentially relieve ulcerative colitis by moderating the gut microbiota and intestinal immunity loop.

The study emphasizes on the possible use of Chinese herbal medicines, which include single herbs, herbal formulas and derived constituents, in treating ulcerative colitis (UC), a recurring inflammatory bowel disease. With a focus on how these medicines interact with and modify the gut microbiota, the mechanism involves regulating the intestinal homeostasis to counter UC. It deals with balancing microbial dysbiosis, or the imbalance of microbes in the body, and abnormal gut immunity, two key initiators of inflammatory responses in UC.

The paper reviews several clinical trials which have been conducted, all exhibiting the effectiveness of Chinese herbal medicines on patients diagnosed with UC. In the trials, these derived substances have shown a protective effect against UC, offering the potential possibility of them being explored as conventional methods of UC treatments in the future. Not every trial has resulted in absolute success, but the overall results are promising and indicate a robust potential direction for UC treatment science.

Chinese herbal medicine shows promising and safe outcomes in relieving functional dyspepsia symptoms and associated psychological disorders.

The methodology for this research involved a comprehensive search across various libraries and databases, such as PubMed, Embase, Cochrane Library, Web of Science, and various Chinese data sources, seeking randomized controlled trials where functional dyspepsia was treated with Chinese herbal medicine. The aim was to assess the efficacy and safety of this type of treatment for functional dyspepsia. Two researchers independently conducted each stage of the process, from searching the sources, screening the documents, extracting data, and assessing risk biases within the included studies. They used RevMan 5.4 software to do a meta-analysis of the selected research materials.

The discussion of their findings showed that treatment with Chinese herbal medicine significantly alleviated the symptoms of functional dyspepsia, compared to both a placebo group and a group treated with traditional prokinetic agents and flupentixol melitracen. Patients treated with Chinese herbal medicine reported higher total effective rates and lower total symptom scores, along with smaller depression and anxiety scores. The symptoms of functional dyspepsia, in this case, were improved more successfully with Chinese herbal medicine than with other treatment types, without any significant adverse reactions.

Coconut water and coconut milk ameliorate the negative impacts of heat stress on gastrointestinal health by reducing oxidative stress and suppressing inflammatory responses.

The study enlisted four different temperature exposure groups of rats, namely a control group at 30 degrees Celsius, a heat-stressed group exposed to an ambiance of 40 degrees, a heat-stressed group pre-treated with coconut water, and a heat-stressed group with coconut milk. Measurements such as skin and rectal temperatures, as well as evaluations of gastrointestinal motility factors such as intestinal transit, intestinal fluid accumulation, and colonic motility, were taken before and after a two-hour heat exposure over 14 days.

Noticeable increases in gastrointestinal motility factors were observed amongst the heat-stressed rats. However, the introduction of coconut milk and water appeared to reverse these increases. Furthermore, the elevated cortisol levels and intestinal lipid peroxidation in the heat-stressed rats were significantly reduced with the introduction of both coconut products. Likewise, results showed an increase in antioxidant enzyme activities in the rats that received either coconut water or milk, in contrast to the control group. Similarly, the coconut water and milk were seen to suppress inflammatory cytokines while enhancing others. The study also noted significant improvements in intestinal morphology among heat-stressed rats treated with either coconut product.

Omega-3 fatty acids can help prevent and manage chronic inflammatory diseases, including ulcerative colitis and rheumatoid arthritis, through influencing gut microbiota.

The study primarily encompasses a review of both experimental and clinical studies on the influence of omega-3 fatty acids on chronic inflammatory conditions, with the attention being specifically focused on those diseases with an autoimmune background. The study highlights the role of these fatty acids in maintaining bodily homeostasis, as well as the enzymatic processes they trigger within the body upon ingestion. Natural sources of omega-3 are also explored, emphasizing the importance of maintaining a healthy and balanced diet.

In their exploration of omega-3's impact on inflammatory conditions, the researchers revisit the pathogenesis of ulcerative colitis and rheumatoid arthritis under the theoretical approach of gut microbiota dysbiosis. This approach emphasizes the role of the gut in maintaining health and identifies how imbalances can contribute to the development and persistence of these conditions. The researchers propose that omega-3 fatty acids are able to prevent and control these conditions, which are significant contributors to global chronic health burden and can lead to severe complications and disabilities if not treated. The potential of omega-3's to prevent severe illness in cases of COVID-19 infection through immune system modulation and control of the inflammatory process is also briefly explored.

Acupuncture can regulate both innate and adaptive immunity of IBD patients, including the balance of Th17/Treg and Th1/Th2 cells, and also modulate intestinal flora.

The methodology of the research revolved around a review of existing studies related to the treatment of Inflammatory Bowel Disease (IBD) via acupuncture. The broad scope of exploration focused on the effects of acupuncture on the immunomodulatory mechanism inherent in these patients. The review pursued a detailed study of how acupuncture directly influenced both the innate and adaptive immunity systems in IBD patients as well as its regulation on their intestinal flora.

The results discussion revealed that acupuncture had multiple immunomodulatory effects on IBD patients. On one hand, it influenced their innate immunity by regulating elements such as their intestinal epithelial barriers, toll-like receptors, NLRP3 inflammasomes, oxidative stress, and endoplasmic reticulum stress. On the other hand, it affected their adaptive immunity by modulating the balance of Th17/Treg and Th1/Th2 cells. Furthermore, an interesting revelation from the study was that acupuncture could also significantly regulate the intestinal flora of the patients.

The Chaihu Shugan Formula, a traditional Chinese medicine, not only effectively modulates intestinal gut microbiota but also strengthens gut barrier integrity and contains powerful anti-inflammatory properties.

The study began by analysing the impact of the Chaihu Shugan Formula (CSF) on the simulated colonic microbiota of five healthy donors, while concurrently examining gut barrier integrity, and intestinal immunity. This was achieved by marrying the use of the simulator of the human intestinal microbial ecosystem technology platform with the co-culture of intestinal and immune cells. The examination revealed an increase in the production of certain healthy short-chain fatty acids, a boost in health-promoting Bifidobacterium species, and a decrease in certain pathogenic branching short-chain fatty acids.

The proceeding phase of the study investigated the influence of colonic fermentation of CSF on gut barrier and intestinal immunity utilizing the Caco-2/THP1-blue™ cell co-culture model. The research demonstrated that CSF induces protective effects on inflammation-induced intestinal epithelial barrier disruption. Concurrently, the study benignly revealed the treatment of CSF unfailingly unveiling pronounced anti-inflammatory properties induced by the stimulation of anti-inflammatory cytokines IL-6 and IL-10 and the reduction of the pro-inflammatory cytokine TNF-α.

Traditional Chinese medicine infant massage can reduce the symptoms of constipation in children suffering from functional constipation.

A review of 23 studies involving 2,005 patients found that traditional Chinese medicine (TCM) infant massage was more effective than drug therapy alone for treating infant functional constipation. The massage showed significant improvements in overall effectiveness, frequency of bowel movements, and constipation symptoms. However, there was no significant difference between the massage and drug therapy when it came to stool form and difficulty of defecation. The variations in results may be due to factors like patient conditions, different massage techniques, the effectiveness of drugs used in the control group, and variations in criteria for measuring effectiveness. The study did not detect any publication bias.

Traditional Chinese Medicine shows promise in preventing cholelithiasis recurrence post lithotripsy

Traditional Chinese Medicine (TCM) may enhance prognosis for cholelithiasis patients following gallbladder-preserving lithotripsy. This systematic review analyzed TCM's efficacy and safety in this context, along with functional pathway enrichment analysis of TCM target genes. Nine randomized controlled trials (RCTs) involving 926 participants were included. Meta-analysis indicated TCM reduced cholelithiasis recurrence, complications, gallbladder wall thickness, and contraction degree. No significant adverse reactions were noted. The study suggested that TCM, particularly the flavonoid glycoside naringin from Glycyrrhiza uralensis, could be beneficial post-gallbladder-preserving lithotripsy, but further high-quality RCTs are needed for a conclusive assessment.

Recent systematic reviews and meta-analyses of nut RCTs showed that almonds were the only nut that had a small but significant decrease in both mean body mass and fat mass, compared to control diets.

The biological mechanisms for almond weight control include enhanced displacement of other foods, decreased macronutrient bioavailability for a lower net metabolizable energy (ME), upregulation of acute signals for reduced hunger, and elevated satiety and increased resting energy expenditure.

Acupuncture is shown to be a beneficial supplementary treatment for chronic abdominal pain, improving patients' quality of life and cutting healthcare costs.

The research explores the utilization of acupuncture to treat chronic abdominal pain, a condition widespread and chiefly affected by Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD). This type of pain is defined by three episodes of severe abdominal pain over a span of three months. While its causes are still being looked into, it is believed to be an outcome of the chronicity of acute pain or chronic pain syndromes. A wide array of treatments for these conditions exist but often fall short of fully controlling the symptoms. Acupuncture, a form of traditional Chinese medicine based on the concept of rebalancing the patient's Qi, or Ying/Yang balance, is being investigated as a complementary method.

In terms of results, acupuncture has proven effective in providing additional alleviation of symptoms, leading to improved quality of life and reduced disability for patients affected by chronic abdominal pain. While it's not a curative solution, it aids in minimizing symptoms and enhancing overall life quality. It is also considered a safe and inexpensive alternative that may result in significant healthcare savings. Notably, it's not recommended for all patients; its benefits seem to be more pronounced in a select group.

Chinese medicine presents unique advantages in managing Inflammatory Bowel Disease (IBD) through immune regulation, intestinal flora regulation, and improvement of intestinal barrier function.

In their research, the researchers conducted a systematic review of studies that assessed the effects and mechanics of Chinese medicine in treating IBD. They performed a literature search on various peer-reviewed and clinical databases, including reputable international and Chinese sources. The keywords used for this comprehensive search included "inflammatory bowel disease", "Ulcerative colitis", "Crohn's disease", and "Chinese medicine". Only articles from the period of 1997-2021 that met their exclusion criteria were chosen for the review.

The compiled research illuminates recent progression in using Chinese medicine to treat IBD. Certain studies specifically look at how Chinese medicine impacts immune regulation, intestinal flora regulation, and the enhancement of intestinal barrier function in IBD patients. This information could serve as a key reference for further exploration regarding the potential of classical multi-herbal Chinese medicine in treating IBD.

Acupuncture has shown promise as a complementary approach in treating chronic abdominal pain, providing symptom relief and improving quality of life.

The methodology revolves around applying acupuncture, a form of integrative medicine from traditional Chinese medicine, to patients suffering from chronic abdominal pain. This pain is defined as having three severe abdominal pain instances over three months, often caused by chronic acute pain or chronic pain syndromes, primarily IBS and IBD. Despite existing treatments, these often fail to control the symptoms completely, leaving room for complementary methods like acupuncture. This practice is based on rebalancing a patient's Qi, or Ying/Yang balance, previously shown effective in treating various conditions.

The results reveal that acupuncture can serve as a crucial adjunct in managing chronic abdominal pain. It is not a cure, but it significantly aids in symptom reduction and quality of life improvement. Particularly for those affected by IBS and IBD, acupuncture offers extra relief from lingering symptoms, thereby improving quality of life, decreasing disability, and potentially contributing to healthcare cost savings. Acupuncture has emerged as a safe, inexpensive, and beneficial approach for selected patients suffering from chronic abdominal pain.

Using a combined treatment of modified Buzhong Yiqi decoction and Gangtai ointment improves wound healing and anal function for circumferential mixed hemorrhoid patients.

The researchers enrolled 120 patients with circumferential mixed hemorrhoids into this trial. After undergoing a surgical procedure, these participants were randomly sorted into two groups for treatment. The control group received chitosan hydrogels for wound healing on a daily basis. Meanwhile, the research group was treated with a daily oral dose of modified Buzhong Yiqi decoction together with Gangtai ointment applied externally twice a day for two weeks. Observations for comparison between groups included effective rates, pain indexes, perianal edema scores, quality of life score, wound healing and pain resolution times, anal functions, wound exudate scores, as well as adverse reactions.

In comparing the results of the experiment, it was found that the modified Buzhong Yiqi and Gangtai ointment combination gave better results across most measured outcomes. The research group showed a higher effective rate, reduced pain, and less perianal edema. The group's quality of life was improved, and their wounds healed more quickly with less pain experienced during recovery. Being able to maintain anal function was found to be more successful in the research group, and they had fewer incidences of adverse reactions. Furthermore, changes in wound exudate scores at 7 and 14 days post-treatment were lesser than those observed in the control group.

Eating fruits such as blueberry, prunes, kiwi, and raisins positively influences gut bacteria leading to improved bowel movements and constipation relief.

The research was conducted via a comprehensive review of animal and human studies investigating the impact of various fruits on gut motility and intestinal microbiota. Techniques used to gather data included electronic database searches, hand searches, and expert consultation. Fruits evaluated in the review included blueberries, prunes, kiwi fruit, and raisins, with an emphasis placed on their fiber, sorbitol, and (poly)phenol content. Each fruit's influence was studied in relation to its potential to modify gut microbiota and its consequences on gut motility and constipation.

In the subsequent analysis, Blueberry powder was found to influence certain gut bacteria like lactobacilli and bifidobacteria, prunes contributed to the growth of bifidobacteria, kiwi fruit impacted Bacteroides, and raisins had an effect on Ruminococcus. Apart from these, other fruits like apples (through apple fiber isolate), oranges (orange extract), and fig (fig paste) were also cited for their crucial effects on gut transit time and overall digestive health. The mechanism behind these effects, the specific components playing a role, as well as the potential synergistic effects of multiple components were also explored, albeit limitedly.

Acupuncture treatment can improve the clinical effectiveness of diarrhea-predominant irritable bowel syndrome or functional diarrhea.

In this systematic review and meta-analysis, the effectiveness and safety of 31 acupuncture concerned studies for patients with IBS-D or FD were evaluated. We found that acupuncture can significantly reduce the number of stools per week in IBS-D or FD patients, improve patients’ overall symptoms, improve the total effective rate, decrease the recurrence rate, and reduce the pain level of patients. Based on the results, we believe that acupuncture can improve the quality of life of patients with IBS-D or FD. Although the number of adverse events in the acupuncture group was similar to that in the control group, the majority of adverse events in the acupuncture group were subcutaneous hemorrhage. With such slight adverse events, we have observed that acceptance among patients has not been reduced. Moreover, the withdrawal rate of patients in the acupuncture group was still slightly lower than that in the control group.

Ban Xia Xie Xin decoction has shown superior effectiveness and safety for treating chronic atrophic gastritis than patent medicine plus western medicine.

In an analysis of the clinical efficacy and safety of Banxia Xiexin decoction (BXD) for chronic atrophic gastritis (CAG) treatment, seven electronic databases, including Ovid, Embase, PubMed, Cochrane Library, and more, were used. The criteria for inclusion in the study were up until September 21, 2020. A Jadad scale coupled with Cochrane Collaboration's risk of bias tool evaluated methodological quality.

Out of the 1985 patients identified for analysis across 26 randomized controlled trials, it was found that BXD treatment provided more effective and safe results than Chinese patent medicine in conjunction with western medicine. Additionally, BXD was seen to improve symptom scores for stomach distending pain and belching. It was also observed that BXD effectively inhibited Helicobacter Pylori, improved HP-related inflammation, and alleviated the degree of glandular atrophy, intestinal metaplasia, and dysplasia of gastric mucosa. Despite the promising results, limitations were identified in relation to methodological quality and sample size across the studies.

Chinese medicine herb Bai Zhu might combat chronic gastritis by influencing inflammatory response, amino acid synthesis and energy metabolism.

Methodology: Network pharmacology was employed to study the active ingredients, drug targets, and critical pathways of AMK in treating chronic gastritis. Initially, four databases were scoured to single out 77 candidate ingredients of AMK, reducing that to 27 active ingredients identified for CG treatment. Furthermore, 25 overlapping gene symbols linked to CG and drugs were procured from GeneCards and OMIM databases. The construction of a protein-protein interaction network and TCM comprehensive network followed this, resulting in 528 Gene Ontology terms and 26 pathways obtained through GO pathways and KEGG pathways enrichment analyses.

Results: The investigation focused on the interleukin-17 signaling pathway, C-type lectin receptor signaling pathway, tumor necrosis factor signaling pathway, and AGE-RAGE signaling pathway in diabetic complications as crucial points and leading pathways for treating chronic gastritis. The study suggests that AMK potentially impacts the inflammatory response, amino acid synthesis, and energy metabolism. These influential active ingredients and targets have been experimentally validated for reliability, offering new insights into the systematic exploration of the traditional Chinese medicine mechanism of action.

Mu Dan Pi (MDP) and its water extract may serve as potential treatment options for inflammatory bowel disease.

In the study, the anti-inflammatory impacts of Mu Dan Pi and its primary active compounds on inflammatory bowel disease were assessed systematically. Screening was done via NF-κB and interferon regulatory factor reporter assays in THP-1 cells, stimulated with particular gene activators. This process was later verified in bone marrow-derived macrophages. The water extract of Mu Dan Pi considerably hindered the activation of NF-κB and IRF reporters, modifying downstream signaling pathways and decreasing the production of IL-6 and TNF-α, based on dosage.

In subsequent observations, among the five known active components identified within Mu Dan Pi, one component known as PGG distinguished itself as the most effective at inhibiting reporters and reducing IL-6 and TNF-α. On a clinical application level, both MDP powder and its water extract mitigated colitis and pathological changes in mice, although PGG did not present any significant reduction. This suggests that the anti-inflammatory qualities of Mu Dan Pi may hold therapeutic potential for inflammatory bowel disease.

Acupuncture could be used as an adjunct in clinical settings to improve efficacy of western medicine for irritable bowel syndrome.

Taken together, for improvement of IBS symptoms and quality of life, no difference was found in acupuncture relative to sham controls studies, while some studies indicated positive results of acupuncture in alleviating IBS symptoms, reflective of a larger potential for treating IBS by true acupuncture. Acupuncture seemed to be superior over western medicine, but the placebo effects couldn’t be ignored for all the studies were conducted in China. Acupuncture might be used as an adjunct to western medicine, herbal medicine and tuina for a better clinical effect. Future high-quality and large-sample studies with adequate stimulation amounts need to be conducted for further testing.

Peppermint oil significantly reduces colonic spasm during colonoscopy, but does not affect the adenoma detection rate or cecal intubation time.

The methodology of this research primarily involved a review of randomized controlled trials that compared the use of peppermint oil and a placebo during colonoscopies. The various trials selected for review were identified through comprehensive searches of databases such as Medline, Google Scholar, and Cochrane up until May 2019. The analysis took into account key variables, including the extent of peristalsis inhibition, cecal intubation time, and adenoma detection rates.

In terms of results, there was significant variation in the dosage and administration of the peppermint oil among the 5 trials that qualified for the review. Comparisons were made between a group of 623 subjects who received peppermint oil and a placebo group of 239 individuals. It was found that peppermint oil led to a significant increase in the complete inhibition of colonic peristalsis. However, the cecal intubation times and adenoma detection rates were similar across both the peppermint oil and placebo groups, despite the high level of variation observed.

Oats improve gastrointestinal health, reduce cholesterol, and regulate satiety, with effects on the gut microbiome constituting an appealing new research area.

The researchers undertook a comprehensive literature review using predefined search criteria and keywords related to gastrointestinal health outcomes in the PubMed database. They sought to explore the impact of oats on gastrointestinal health in humans, with the intent to identify both human and animal studies, as well as in vitro studies, that met their specific inclusion criteria. They extracted data from eight human studies, nineteen animal trials, and five in vitro studies for this synthesis.

The results underscore that oats, due to their unique composition of bioactive compounds, lipids, and β-glucan, have beneficial effects on gastrointestinal health. The human studies showed consistent beneficial outcomes, with complementary evidence from animal and in vitro studies. The degree of effect, however, appeared to vary depending on the type of oats and dosage used. For instance, oat types providing between 2.5 to 2.9 grams of β-glucan a day were found to decrease fecal pH and alter fecal bacteria, while 40 to 100 grams per day of oat bran was shown to boost bacterial mass and short-chain fatty acids in human feces. The researchers note that different study designs, methodologies, and types of oats used make comparing results challenging.

Acupuncture in conjunction with Chinese medicine has shown a higher efficiency compared to only Chinese medicine in haemorrhoids treatment.

The research adopted a systematic review and meta-analysis of randomized clinical trials using Review Manager 5.3. It highlighted and evaluated trials where the combined treatment of acupuncture and Chinese medicine was compared against Chinese medicine alone for haemorrhoids. The parameters taken into account for the outcomes of this analysis included the effective rate, recurrence rate, and symptom scores before and after treatment. These symptoms comprised perianal edema, hemafecia, perianal pain, pruritus ani, and prolapse of haemorrhoids.

The results from the trials included in this meta-analysis, showed a distinct improvement in clinical efficacy for the combined use of acupuncture and Chinese medicine over just Chinese medicine alone in the treatment of haemorrhoids. Not only was the effective rate higher, but the recurrence rate was lower. Furthermore, there was significant improvement in all the assessed symptoms – perianal edema, hemafecia, perianal pain, pruritus ani, and prolapse of haemorrhoids - showing a more comprehensive treatment impact. The experiment's combined treatment displayed a 7% higher efficiency compared to the control group just using Chinese medicine.

Drinking alkaline-reduced water can improve the quality of life in patients suffering from diarrhea-predominant irritable bowel syndrome.

In this study, twenty-seven patients with diarrhea-predominant irritable bowel syndrome were divided into two groups: one group that drank at least 2 liters of alkaline-reduced water a day, and a control group that drank placebo water. The duration of the experiment was eight weeks, during which symptom scores (including quality of life and abdominal pain/discomfort), stool form, and frequency were evaluated via questionnaires both before and after the treatment duration.

The results indicated that an overall greater percentage of patients in the alkaline-reduced water group experienced symptom improvement across the majority of the treatment period compared to the control group. Specifically, the quality of life score in the alkaline-reduced water group significantly improved, a change which was significantly more substantial than the minor improvement seen in the control group. The report about abdominal pain also showed its reduction in both groups, but this change did not significantly differ between the two groups.

The herbal formula Modified Bu Zhong Yi Qi Tang significantly improves functional constipation symptoms with fewer adverse events.

Method: Extensive research was conducted on the formula Modified Buzhong-Yiqi-Tang (MBYT) used for adult patients suffering from functional constipation. Twenty-five randomized controlled clinical trials were selected and undertaken in accordance with predefined criteria. A total of 2089 patients' symptoms and responses to treatment were evaluated and compared against the effects of stimulant laxatives, osmotic laxatives, and prokinetic agents. The study also evaluated MBYT's efficacy as an adjuvant therapy.

Discussion of Results: The research found that MBYT treatment made significant improvements to patients' constipation symptoms when compared to other treatments. As an adjuvant therapy, it showed superior results in comparison to osmotic laxatives alone, prokinetic agents alone, and biofeedback alone.

Patients receiving acupuncture combined with western medicine had a superior global symptom improvement compared with those receiving western medicine alone for gastro-oesophageal reflux disease.

A total of 12 trials involving 1235 patients were included. Meta-analyses demonstrated that patients receiving MA/EA combined with WM had a superior global symptom improvement compared with those receiving WM alone with no significant heterogeneity. Recurrence rates of those receiving MA/EA alone were lower than those receiving WM with low heterogeneity, while global symptom improvement (six studies) and symptom scores (three studies) were similar. Descriptive analyses suggested that acupuncture also improves quality of life in patients with GORD.

Chinese herbal medicines showed greater improvement in terms of clinical efficacy in the treatment of irritable bowel syndrome with constipation than cisapride and mosapride.

Eleven eligible studies comprising a total of 906 participants were identified. In the primary outcome, TCM showed significant improvement in overall clinical efficacy compared with cisapride and mosapride. In terms of secondary outcomes, TCM significantly alleviated abdominal pain, defecation frequency, and stool form in the treatment group as compared to the control group. A lower recurrence rate was associated with TCM as compared to cisapride and mosapride. No adverse effects were observed during TCM treatment.

TCM showed greater improvement in terms of clinical efficacy in the treatment of IBS-C than cisapride and mosapride, although it was not possible to draw a definitive conclusion due to the small sample size, high risk, and low quality of the studies. Large multi-center and long-term high-quality randomized control trials are needed.

The study indicates a positive link between Irritable Bowel Syndrome (IBS) and Blastocystis infection, with no such association found for Dientamoeba fragilis infection.

For the methodology, a comprehensive search was conducted on academic databases including PubMed, ScienceDirect, Scopus, Web of Science, and Cochrane up until February 2017, to gather studies relating to the potential association between IBS and the infections of Blastocystis and Dientamoeba fragilis. From these sources, 17 relevant studies encompassing 5882 participants (2527 patients and 3310 controls) were chosen. Pooled odds ratio and confidence intervals were computed utilizing a random effects meta-analysis model.

In the discussion, the analysis showed that individuals with Blastocystis infection are more likely to have IBS. This association was not seen with Dientamoeba fragilis infection. Additionally, in a subgroup analysis for Blastocystis infection, there were significant positive associations in all control groups. Subtypes ST1 and ST3 of the Blastocystis infection were also recognised as potential risk factors for IBS. Thus, the results affirm a positive relationship between Blastocystis infection and IBS.

Acupuncture was superior to either sham acupuncture or medication (including Itopride, Mosapride, and Domperidone) in relieving the major symptoms of functional dyspepsia.

Acupuncture therapy (including manual and electroacupuncture) achieved statistically significant effect in improving the overall symptoms and quality of life of functional dyspepsia patients comparing to sham acupuncture and is superior to medication (prokinetic agents) in ameliorating the major symptoms of functional dyspepsia (postprandial fullness and early satiation).

Pu-erh tea's fermentation process alters its microbial community, with aging significantly impacting raw but not ripened Pu-erh, and toxic metabolites present support brewing customs.

The researchers looked into the microbial communities inherent in Pu-erh tea, a special blend originating from Yunnan, China. The fresh leaves of the tea plant, Camellia sinensis, undergo two types of fermentation- the traditional raw fermentation and the faster, ripened variant. Using high-throughput rDNA-amplicon sequencing, a method to identify and quantify various bacteria and fungi present, they examined both the leaves and both types of Pu-erh tea. The study also explored possible mycotoxins in the tea profiles through quantitative liquid chromatography-tandem mass spectrometry, a technique used to detect and quantify various substances.

Despite observing significant alterations in the fungal and bacterial compositions due to both fermentation processes, the researchers found the aging process to produce noteworthy changes in raw Pu-erh but not in the ripened type. They identified 390 fungal operational taxonomic units (OTUs) and 629 bacterial OTUs in the leaves and teas. Interestingly, despite the difference in the speed and nature of the fermentation processes, ripened and well-aged raw Pu-erh teas exhibited similar microbial communities alien from those observed in young, raw Ph-erh tea. They also found 25 toxic metabolites, primarily of fungal origin, with the most common being patulin and asperglaucide. These facts lend credibility to the Chinese custom of discarding the first preparation of the Pu-erh tea and using the damp tea for subsequent brewing.

Acupuncture and moxibustion therapy show greater effectiveness than oral sulphasalazine in treating inflammatory bowel diseases.

For the methodology, seven significant databases, both domestic and international, were meticulously searched to accumulate and examine randomized controlled trials (RCTs). These trials specifically compared acupuncture and moxibustion as the main intervention to pharmacotherapy in treating Inflammatory bowel diseases (IBD). In total, 43 RCTs were incorporated and examined, 10 of which distinctly compared oral sulphasalazine with acupuncture or/and moxibustion treatments.

In regards to the results received, the study found that acupuncture and moxibustion therapy displayed superior results when compared with oral sulphasalazine. This conclusion is drawn from the meta-analysis of the 10 trials focusing specifically on these treatments. Even though the systemic review presented several limitations and a definitive conclusion wasn't reached, it still laid groundwork for the potential effectiveness of acupuncture and moxibustion therapy in managing Inflammatory bowel diseases.

The traditional Chinese medicine diagnosis of Cold and Hot Syndromes based on tongue-coating appearance successfully detects signals in the tongue-coating microbiomes that are indicators of the entire body's status.

In summary, by studying the tongue-coating microbiomes of chronic atrophic gastritis patients and healthy controls using next-generation sequencing and bioinformatics analysis, we revealed the possible mechanism underlying the traditional tongue diagnosis and highlighted the potential for using tongue coating microbiome features as biomarkers to reflect the holistic status of the human body, especially in gastrointestinal diseases. The current sample size of this study is still small and further investigations with more samples and complete metagenome sequencing are needed for a comprehensive understanding of the system. The observations described here might provide a new direction for understanding the biological basis of TCM tongue diagnosis and the link between the “geographic tongue” and the human body's health status observed in modern Western medicine.
