Xiao Yao San can improve symptoms and reduce recurrence rates in patients with disorders of gut-brain interaction.

The paper's methodology involved a meta-analysis of randomized controlled trials found in seven databases, up until November 22, 2021. The trials, which totaled 48 all together, were included to determine the efficacy of Xiao-Yao-San in treating disorders of gut-brain interaction (previously known as functional gastrointestinal disorders). A range of measures, including therapeutic efficacy, symptom score, Self-Rating Anxiety Scale score, Self-Rating Depression Scale score, and the recurrence rate, were analysed using both random-effects and fixed-effects models, as well as trial sequential analysis.

In terms of results, Xiao-Yao-San showed a marked improvement in the effective rate of managing disorders of gut-brain interaction compared to western drugs, both when used alone and in combination with western medicine. The paper also found the treatment notably reduced symptom scores, anxiety scores, and depression scores for patients with the disorder. Further, instances of recurrence were also reduced. Overall, Xiao-Yao-San was well tolerated and no serious adverse events were reported in any of the trials included in this analysis.

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.

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.

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.

Adzuki beans, when added to a high-fat diet, lessen obesity, improve liver function, enhance insulin sensitivity, and balance gut microbiota.

In the experiment, mice were placed on one of three diets for 12 weeks: a low-fat diet, a high-fat diet, or a high-fat diet supplemented with 15% adzuki beans. The study observed and tested for changes related to obesity, lipid accumulation, serum lipid and lipopolysaccharide levels, liver function, hepatic steatosis, glucose homeostasis, insulin sensitivity, and gut microbiota imbalances. Through a process called PICRUSt2 analysis, the researchers were then able to draw potential associations between changes in the gut microbiota and the metabolism of various substances.

In the discussion of the results, the supplementation of adzuki beans to a high-fat diet had a significant impact. Obesity and lipid accumulation were visibly reduced, as were negative impacts on liver function and unhealthy levels of serum lipids and lipopolysaccharides. Notably, glucose homeostasis was improved through an increase in insulin sensitivity. The imbalances in gut microbiota, typically seen in a high-fat diet, were significantly reversed through adzuki bean supplementation. High-fat diet dependent taxa returned to a more normal status, which in turn suggested associations with the metabolism of carbohydrates, lipids, sulfur, and two types of amino acids.

Small-intestinal release peppermint oil is a cost-effective treatment for Irritable Bowel Syndrome, yielding modest quality of life gains and relieving abdominal pain.

In the research study, a multicenter, randomized, placebo-controlled trial was carried out to evaluate the cost-effectiveness of small-intestinal release peppermint oil - an often used treatment - in patients with Irritable Bowel Syndrome (IBS). The cost-effectiveness was analyzed from a societal perspective, using two different approaches: costs per Quality of Life Years (QALY) and costs per successfully treated patient or abdominal pain responder. The later was defined according to Food and Drug Administration (FDA) definitions. Sensitivity analyses were also conducted to further substantiate the results. This comprehensive evaluation involved 126 IBS patients randomly assigned to receive either placebo or peppermint oil.

The findings showcase that peppermint oil took precedence as a dominant and effective treatment compared to placebo in considerable number of cases. Not only did it prove more successful at reducing the abdominal pain experienced by IBS patients, but analysis also positioned it as a viable option with regards to the cost-effectiveness ratio based on QALY. The results displayed that peppermint oil came out as a financially savvy treatment in varying scenarios, demonstrating a high probability of cost-effectiveness when evaluated using the abdominal pain responder outcome measure.

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.

Ginger has been effective in a majority of studies, including those that examined the alleviation of nausea and vomiting of pregnancy, digestive function, improvement in the expression level of markers for colorectal cancer risk, and anti-inflammatory functions.

Ginger is a natural spice that is used in diverse regions to add a pungent flavor to food. Furthermore, ginger has been used as an herbal medicine for common health problems. This systematic review is the first study that has exclusively collected RCTs regarding the efficiency of ginger in several human health conditions. The clinical effects of ginger have been introduced as six subsections: nausea and vomiting, gastrointestinal function, pain, inflammation, metabolic syndromes, and other symptoms. Reportedly, ginger has been effective in a majority of studies, including those that examined the alleviation of nausea and vomiting of pregnancy, digestive function, improvement in the expression level of markers for colorectal cancer risk, and anti-inflammatory functions. Several other functions have also been regarded as beneficial in trials, with some confronting results. However, a few drawbacks regarding the quality of the trials, inconsistent evaluation systems or parameters, and the generally small size of the studies need to be noted. Therefore, systematically designed research with detailed descriptions of methodology and a sufficient pool of participants is necessary for future clinical trials to address the functional characteristics of ginger.

Acupuncture shows promise in treating postcholecystectomy syndrome.

Acupuncture may offer relief for Postcholecystectomy Syndrome (PCS), as revealed by a systematic review and meta-analysis of 14 RCTs with 1593 participants. While acupuncture combined with conventional medicine didn't significantly reduce pain, it significantly lowered postoperative nausea and vomiting incidence and improved gastrointestinal recovery compared to conventional medicine alone. However, the study acknowledges the limitations of included RCTs, including small sample sizes and low methodological quality. Further high-quality trials conforming to standardized reporting are needed to validate these findings. Adverse events related to acupuncture were reported as mild and acceptable. Further research is crucial for definitive conclusions regarding acupuncture's efficacy for PCS.

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.

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 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.
