Functional dyspepsia (FD) and gastroparesis (GP) are common disorders of the upper gastrointestinal tract. The pathophysiology of these conditions is likely to be heterogenous, and factors such as altered motility, sensitivity and response to nutrition have been identified as putative underlying mechanisms. Motility, sensitivity as well as responses to nutrition can be influenced or mediated by peptide hormones and serotonin released from the gastrointestinal mucosa. This review summarizes the role of GI peptides in functional dyspepsia and gastroparesis. In most studies, the levels of somatostatin, ghrelin, and motilin did not differ between healthy volunteers and FD or GP patients, but higher symptom burden was often correlated with higher peptide levels. Ghrelin and motilin receptor agonists showed promising results in improvement of the gastric emptying, but the link with improvement of symptoms is less predictable. Serotonin agonists have a potential to improve symptoms in both FD and idiopathic gastroparesis. Drugs acting on the GLP-1 and on the PYY receptors deserve further investigation. There is a need for systematic large scale studies.

Meta-Analysis
BACKGROUND
Nutritional problems in the early stages of severe burns are prominent and seriously affect the clinical outcomes of patients. Our aim is to analyze the effects of early enteral nutrition (EEN) in patients with severe burns.
METHODS
In this study, relevant articles were searched in 8 English and Chinese data, with a time limit from the creation of the database to June 2023. Two researchers independently completed the search, screening and quality assessment of the articles. We conducted a systematic review and meta-analysis of randomized controlled trials that examined EEN therapy in people with severe burns. We compared the effects of EEN and non-EEN therapy in severely burned patients. The outcomes were mortality, gastrointestinal complications, nutritional indicators, gastrointestinal hormones, sepsis, length of hospital stay and wound healing time. Categorical variables were expressed as OR and 95% CI was calculated, and continuous variables were expressed as MD and 95% CI was calculated. The protocol for this systematic review was registered in PROSPERO on May 12, 2023 (identifier CRD42023422895).
RESULTS
Nineteen studies with a total of 1066 participants met the inclusion criteria. When comparing EEN therapy with non-EEN therapy, the experiment group had significantly lower mortality [OR = 0.39, 95% CI (0.20, 0.74), P = .004], lower wound healing time [MD = -10.77, 95% CI (-13.66,-7.88), P < .00001], fewer gastrointestinal complications [OR = 0.18, 95% CI (0.09, 0.36), P < .00001], lower rates of gastrointestinal hemorrhage [OR = 0.12, 95% CI (0.04, 0.36), P = .0001], lower rates of sepsis [OR = 0.40, 95% CI (0.24, 0.66), P = .0005], shorter length of hospital stay [MD = -12.08, 95% CI (-13.61, 9.19-10.56), P < .00001], and higher prealbumin levels [MD = 29.04, 95% CI (21.98, 36.10), P < .00001], higher total albumin levels [MD = 6.74, 95% CI (4.29, 9.19), P < .00001], and gastrin levels [MD = 15.93, 95% CI (10.12, 21.73), P < .00001]. However, there was no significant difference in albumin between the 2 groups [MD = 2.62, 95% CI (-0.30, 5.55), P = .08] or motilin levels [MD = 12.48, 95% CI (-43.59, 68.56), P = .66].
CONCLUSIONS
EEN plays an important role in the rehabilitation of patients with severe burns. EEN is beneficial to reduce complications and the length of hospital stay, maintain organ function, optimize the nutritional status of patients, promote wound healing, and improve the survival rate of patients.

Meta-Analysis
BACKGROUND
Functional dyspepsia (FD) is a common, etiologically complex disease which persistently and recurrently attacks the digestive system. However, the efficacy of Western medicine in treating FD is unsatisfactory and its use is often accompanied with severe side effects. Here, this study conducted a metaanalysis on the clinical efficacy and safety of the treatment of FD with Xin kai bitter method combined with Western medicine, to produce a more objective and comprehensive systematic review to guide clinical application.
METHODS
Systematic searches were conducted of the PubMed, Cochrane Library, EMBASE, Medline, Web of Science, Wanfang Databases, and Weipu (VIP) databases, as well as China National Knowledge Infrastructure (CNKI). Randomized controlled clinical trials (RCTs) of Xin kai bitter method in the treatment of FD were included in the study. The total effective rate and safety were evaluated with relative risk (RR) and the quantitative data were evaluated with standard mean difference (SMD) and 95% confidence interval (CI). The quality of the included literature was evaluated using RevMan5.3 software, and the "meta" package of R3.5.1 software was used for all other statistical analysis.
RESULTS
A total of 24 papers involving 1,044 patients in the treatment group and 989 patients in the control group were included. A total of 23 articles reported the total effective rate after 1 month of treatment (I2 =0%), and the total effective rate in the treatment group was 1.21 times higher than that in the control group (95% CI: 1.17 vs. 1.26). A total of 4 articles reported the safety rate after 1 month of treatment (I2 =27%); the safety rate in the treatment group was 0.43 times than that in the control group (95% CI: 0.23 vs. 0.82). A total of 8 articles reported traditional Chinese medicine (TCM) symptom score or clinical symptoms before and after 1 month of treatment (I2 =91%), and the difference in TCM symptom score before and after treatment in the treatment group was significantly lower than that in the control group, with a SMD of -1.19 (95% CI: -1.71, -0.66). A total of 6 articles reported the motilin (MTL) level before and after 1 month of treatment, and the difference before and after treatment in MTL in the treatment group was not significantly different to that in the control group, with a SMD of 0.92 (95% CI: -0.12, 1.97).
CONCLUSIONS
Compared to conventional treatment, Xin kai bitter method has a higher clinical effect and lower adverse reaction rate in patients with FD, and can improve TCM symptom score. However, highquality RCT research is still needed to further explore the safety of Xin kai bitter method for treating FD.

Meta-Analysis
BACKGROUND
Functional dyspepsia (FD) is a common functional gastrointestinal disease. Acupuncture, including electroacupuncture (EA) is widely used as a complementary and alternative treatment for patients with FD. This study aimed to explore the effectiveness of EA for the treatment of FD.
METHODS
We searched Embase, PubMed, and the Cochrane Central Register of Controlled Trials (Cochrane Library) for randomized controlled trials of FD treated by EA from inception to February 3, 2020. Two reviewers will independently screen studies for data extraction and assess the quality and risk of bias. The Cochrane Collaboration's risk of bias tool, RevMan 5.3 software were used for meta-analysis. Data were pooled to calculate relative risk and 95% confidence intervals (CIs) of substantial improvement after treatment for dichotomous data and mean differences (SMDs) and 95% CIs for continuous data.
RESULTS
Seven randomized clinical trials included 853 patients. This meta-analysis investigated the effectiveness of EA alone in the treatment of FD relative to sham-EA or pharmacologic medication (PM). The results showed that EA could significantly improve clinical symptoms. Compared with sham-EA, EA was more effective in reducing symptom scores (SMD -3.44, 95% CI -4.21 to -2.67) and increasing normal slow waves of electrogastrogram (SMD 0.93, 95% CI -0.30 to1.55). When EA was combined with PM, there was no significant difference in reducing symptom scores (SMD -0.18, 95% CI -0.51 to 0.16), increasing the effective rate of clinical symptoms (risk ratio 1.04, 95% CI 0.96 to 1.13), enhancing the level of plasma motilin (SMD 0.93, 95% CI -0.30 to1.55), and reducing gastric half-emptying time (SMD 0.02, 95% CI -0.16 to 0.20). The results also showed that there were very few adverse events reported.
CONCLUSION
This meta-analysis suggests that EA is better than the placebo (sham-EA) in treating FD, and the therapeutic effect of EA on FD is equivalent to that of PM on FD. Compared with PM, EA for FD is safer and has fewer adverse reactions. Despite limitations due to the quality and number of the included studies, EA might be used as an effective and safe treatment for FD.

Taste receptors are located on the epithelial surface throughout the alimentary canal to identify nutrients and potential toxins. In the oral cavity, the role of taste is to encourage or discourage ingestion, while in the gastrointestinal (GI) tract, the taste receptors help the body prepare for an appropriate response to the ingested foods. The GI sensing of bitter compounds may alter the secretion of appetite-related hormones thereby reducing food intake, which may have potential use for managing health outcomes. This systematic literature review investigated the acute effects of administering different bitter tasting compounds on circulating levels of selected GI hormones, subjective appetite, and energy intake in humans. A literature search was conducted using Medline, CINAHL and Web of Science databases. Of 290 articles identified, 16 met the inclusion criteria. Twelve studies assessed food intake; four of these found bitter administration decreased food intake and eight did not. Fourteen studies assessed subjective appetite; seven found bitter administration affected at least one measure of appetite and seven detected no significant changes. Nine studies included measures of GI hormones; no significant effects were found for changes in GLP-1, CCK or PYY. Four studies measured motilin and ghrelin and found mostly consistent changes in either food intake or subjective appetite. Overall, the data on food intake and subjective appetite were inconsistent, with only motilin and ghrelin responsive to post-oral bitter administration. There is limited consistent conclusive evidence that bitter compounds influence food intake, appetite or hormones with the reasons for this discussed within.

Meta-Analysis
BACKGROUND
Functional dyspepsia (FD) refers to a group of clinical symptoms caused by gastric and duodenal dysfunction. Which is a chronic functional disorder of the gastrointestinal tract with no cure. Zhishixiaopi decoction (ZSXP) is a type of Chinese herbal prescription that for treating FD. Although some randomized controlled trials (RCTs) report that ZSXP can significantly improve FD clinical symptoms and/or laboratory results, the trial design varies greatly among studies, making it challenging to draw a conclusion of the efficacy of ZSXP in treating FD.
DESIGN
A systematic review and a meta-analysis.
SETTING
Mianyang Central Hospital.
OBJECTIVE
We conducted a systematic review and a meta-analysis to evaluate the efficacy and safety of ZSXP for treating FD.
METHODS
We developed inclusion and exclusion criteria based on FD diagnosed criteria, interventions to treat FD, and outcomes of these interventions. Search strategies combined disease terms, symptom terms, anatomy terms and intervention terms. Literature search was conducted on eight online databases in English or Chinese, including Medline (via PubMed), Embase (via Ovid), The Cochrane Library, Web of Science, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP), and Wanfang Database.
INTERVENTION
The experimental group received oral administration of ZSXP and had a complete treatment process. ZSXP needs to fully contain the key herbal ingredients, regardless of whether the dosage of each herb is consistent with the original prescription. The Control group received monotherapy or combination therapy of other Western medicine and had a complete treatment process.
OUTCOMES
The primary outcomes appraised were Total effective rate (TER), serum levels of Motilin(MOT), Gastrin(GAS) and Somatostatin (SS), Gastric emptying rate (GER) using a Barium meal method (GER(B)) and Gastric half emptying time using an Ultrasonic method (GHET(T1/2)). The Cochrane Bias Risk Tool was used for quality critical appraisal, Review Manager (RevMan) version 5.3 was used for statistical analysis.
RESULTS
A total of 21 medium-quality RCTs were included in the meta-analysis. All 21 included studies were conducted and completed in Mainland China from 1998 to 2020. The treatment duration was between two weeks to two months. The meta-analysis suggests that, compared with the Western medicine treatment group, ZSXP treatment was more effective to improving the TER in FD [Odds ratio, OR = 3.54, 95%CI:(2.49, 5.05), Z = 6.99, P<0.00001] without significant increase in adverse events. However, no statistical significance was found between the groups in serum MOT levels [Standard mean difference, SMD = 1.05, 95%CI:(-0.42, 2.53), Z = 1.04, P = 0.16], serum GAS levels [SMD = -0.16, 95%CI:(-1.20, 0.88), Z = 0.31, P = 0.76], serum SS levels [SMD = -0.04, 95%CI:(-1.97, 1.89), Z = 0.04, P = 0.97], GER(B) [SMD = 1.09, 95%CI:(-0.81, 3.00), Z = 1.12, P = 0.26]or GHET(T1/2) [Mean difference, MD = -2.18, 95%CI:(-5.55, 1.19), Z = 1.27, P = 0.20].
CONCLUSIONS
The meta-analysis suggests that Zhishixiaopi treatment is a relatively effective and safe traditional Chinese medicine prescription and could be used for functional dyspepsia treatment. Considering the limitations of this study, the conclusion needs to be further confirmed by high-quality, multi-center, and large-sample randomized controlled trials.

Meta-Analysis
BACKGROUND
Pediatric functional constipation (PFC) is a prevalent and persistent gastrointestinal disorder, that requires various treatments, including alternative approaches. This review assessed the synergistic efficacy of herbal medicine (HM) and probiotics for PFC.
METHODS
We conducted a comprehensive search of 11 databases, including English, Chinese, and Korean databases, until June 29, 2023. The inclusion criteria were randomized clinical trials (RCTs) comparing the intervention of HM with probiotics to that of the same probiotics. Statistical analyses included calculation of the mean difference (MD), standardized MD, risk ratio (RR) with a 95% confidence interval (CI), and assessment of risk of bias using Review Manager Version 5.4 software. The Grading of Recommendations Assessment, Development, and Evaluation rating system was used to evaluate evidence quality. Potential publication bias was assessed using funnel plots, Egger test, the fail-safe N test, and Duval and Tweedie trim and fill method.
RESULTS
A total of 22 RCTs involving 2228 patients were included in the meta-analysis. The HM and probiotics group exhibited superior outcomes compared to the probiotics alone group in various parameters: total effective rate (RR: 1.24, 95% CI: 1.19-1.29, P < .001), Bristol fecal Score (MD: 0.80, 95% CI: 0.71-0.89, P < .001), gastrointestinal peptide hormone (motilin) (MD: 35.37, 95% CI: 24.64-64.10, P < .001), inflammation indicator (nitrous oxide) (MD: -12.45, 95% CI: -15.12 to -9.77, P < .001), minimal sensitive volume of the rectum (MD: -8.7, 95% CI: -10.91 to -6.49, P < .001), and recurrence rate (RR: 0.30, 95% CI: 0.21-0.43, P < .001).
CONCLUSION
The combination of HM and probiotics may exhibit a synergistic effect on PFC. Nevertheless, it is imperative to undertake rigorously planned RCTs to comprehensively evaluate the synergistic efficacy of HM and probiotics.

Effectiveness of traditional Chinese medicine in treating gastrointestinal dysfunction in patients with acute stroke: a systematic review and meta-analysis of 16 randomized controlled trials.
BACKGROUND
Gastrointestinal dysfunction is one of the complications after stroke. If it is not treated in time, it will affect the rehabilitation process after stroke and reduce the quality of life of patients. In this study, we conducted a systematic review and meta-analysis of the reports on the treatment of gastrointestinal dysfunction after stroke with traditional Chinese medicine (TCM) in recent years to provide evidence for clinical diagnosis and treatment.
METHODS
The clinical randomized controlled trials (RCTs) published in Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Medline, and Web of Science databases from January 2010 to August 2021 were searched. After screening the qualified literatures, literature quality evaluation was performed. The software Stata 16.0 was used to analyze and compare the outcome indicators of TCM and conventional western medicine treatment, and the utility of TCM in the treatment of gastrointestinal disorders after stroke was comprehensively evaluated.
RESULTS
A total of 16 studies were finally selected including a total of 1,589. Meta-analysis showed that TCM treatment of gastrointestinal disorders after stroke was more effective than conventional western medicine treatment [odds ratio (OR) =3.94; 95% confidence interval (CI): 2.63 to 5.89; P=0.000]. It was also shown that TCM can reduce the recovery time of bowel sounds and is superior to conventional western medicine [standard mean difference (SMD) =-1.92; 95% CI: -2.51 to -1.34; P=0.000]; reduce defecation and flatulence recovery time (SMD =-2.51; 95% CI: -3.41 to -1.61; P=0.000); increase gastrin level (SMD =0.80; 95% CI: 0.35 to 1.25; P=0.001); increase motilin level (SMD =2.27; 95% CI: 1.55 to 3.00; P=0.000); increase serum albumin level (SMD =0.72; 95% CI: 0.54 to 0.90; P=0.000); increase transferrin levels (SMD =1.11; 95% CI: 0.86 to 1.36; P=0.000); and it can increase serum prealbumin levels (SMD =1.50; 95% CI: 0.78 to 2.22; P=0.000).
DISCUSSION
The use of TCM in the treatment of gastrointestinal dysfunction after stroke can effectively reduce symptoms, shorten the recovery time of bowel sounds, the first defecation and flatulence time, promote gastric motility and gastrointestinal hormone secretion, and improve the nutritional status of patients.
