Gut microbial communities are likely remodeled in tandem with accumulated physiological decline during aging, yet there is limited understanding of gut microbiome variation in advanced age. Here, we performed a metagenomics-based enterotype analysis in a geographically homogeneous cohort of 367 enrolled Chinese individuals between the ages of 60 and 94 years, with the goal of characterizing the gut microbiome of elderly individuals and identifying factors linked to enterotype variations. In addition to two adult-like enterotypes dominated by Bacteroides (ET-Bacteroides) and Prevotella (ET-Prevotella), we identified a novel enterotype dominated by Escherichia (ET-Escherichia), whose prevalence increased in advanced age. Our data demonstrated that age explained more of the variance in the gut microbiome than previously identified factors such as type 2 diabetes mellitus (T2DM) or diet. We characterized the distinct taxonomic and functional profiles of ET-Escherichia, and found the strongest cohesion and highest robustness of the microbial co-occurrence network in this enterotype, as well as the lowest species diversity. In addition, we carried out a series of correlation analyses and co-abundance network analyses, which showed that several factors were likely linked to the overabundance of Escherichia members, including advanced age, vegetable intake, and fruit intake. Overall, our data revealed an enterotype variation characterized by Escherichia enrichment in the elderly population. Considering the different age distribution of each enterotype, these findings provide new insights into the changes that occur in the gut microbiome with age and highlight the importance of microbiome-based stratification of elderly individuals.

Intestinal flora imbalance and abnormal glucose and lipid metabolism are important risk factors and pathological mechanisms of colorectal polyps. "Spleen deficiency and dampness accumulation" is the core pathogenesis of colorectal polyps. The imbalance of intestinal flora is related to spleen deficiency, and the application of Chinese herbs for invigorating spleen is helpful to the recovery of intestinal flora balance. Abnormal glucose and lipid metabolism is related to dampness accumulation, and it is effective to treat it with bitter and spicy herbs or spleen-invigorating and dampness-eliminating herbs. The interaction between intestinal flora imbalance and abnormal glucose and lipid metabolism changes intestinal microenvironment, damages intestinal epithelial cells, causes abnormal proliferation of intestinal stem cells and leads to colorectal polyps, which is consistent with the pathogenesis of spleen deficiency and dampness accumulation in Traditional Chinese Medicine. Thus, we tried to explore the biological connotation of the pathogenesis of "spleen deficiency and dampness accumulation" of colorectal polyps from the perspective of the interaction of intestinal flora and glucose and lipid metabolism, in order to provide reference for identifying high-risk population and analyzing the therapeutic mechanism of compound prescription for invigorating spleen and removing dampness.

OBJECTIVES:
To evaluate the methodological quality of randomized controlled trials (RCTs) of traditional Chinese medicines for the treatment of gastric precancerous lesions in the past 20 years.
METHODS:
The RCTs on traditional Chinese medicines for gastric precancerous lesions were searched from the CNKI, Wanfang database, VIP, PubMed, and Embase from January 2001 to December 2021. The retrieved articles were screened, extracted and evaluated based on the 2010 edition of CONSORT statement, Cochrane Risk of Bias Assessment Scale and additional evaluation indicators.
RESULTS:
A total of 840 papers were included. According to the Cochrane Risk of Bias Assessment Scale, the high risk of bias in the application of randomized methods was 5.95%; the risk of uncertainty for the allocation scheme concealment was 98.93%; the risk of uncertainty for blinding of patients or testers was 98.69%; the risk of uncertainty for blinding of the outcome assessor was 100.00%; the risk of bias for completeness of the outcome data was 2.86%; and the risk of uncertainty for selective reporting was 98.45%. The CONSORT statement evaluating the quality of reporting showed that 100.00% of the RCT articles reported the 8 entries; 36.79% of the literature mentioned the method of randomized sequence generation, but only 27.62% of the literature mentioned who implemented the randomized program, 1.07% of the literature hid the randomized program and 1.31% of the studies were blinded; 36.67% of the literature reported adverse reactions; no literature reported sample size prediction methods. Additional evaluation indicators showed that 17.02% of the studies had ethical approval; 43.81% of the literature specified Chinese medicine evidence; 16.55% of the studies excluded severe heterotrophic hyperplasia; 7.26% of the studies conducted follow-up; and 65.12% of the literature used composite efficacy indicators; 46.67% of the literature applied pathological histological evaluation; 2.62% of the literature applied quality of life evaluation.
CONCLUSIONS
The overall risk of bias in RCTs of traditional Chinese medicines for gastric precancerous lesions is high, and the quality of most of the study reports needs to be improved. In the future, it is necessary to strengthen the study design of RCTs and refer to appropriate traditional Chinese medicines evidence grading standards, select study protocols according to different purposes, provide objective and strong evidence for clinical studies on traditional Chinese medicines, and carry out clinical study design and result reporting suitable for traditional Chinese medicines according to the CONSORT principle.

Objective:To conduct a network meta-analysis comparing the efficacy and safety of various drug injections for treating keloids.Methods:The search terms of "triamcinolone acetonide, 5-fluorouracil, verapamil, botulinum toxin, platelet rich plasma, keloid, scar, drug injection" were retrieved in PubMed, Embase, Web of Science, CNKI and Wanfang database to obtain the publicly published randomized controlled trials comparing single or combined drug injection for treating keloid from January 2010 to February 2023. The outcome index was the effective proportion of treatment, incidence proportion of adverse reactions, and recurrence proportion. NoteExpress, RevMan 5.4, and Stata 16.0 statistical software were utilized to perform a network meta-analysis of eligible studies that met the inclusion and exclusion criteria.Results:A total of 1 679 patients were enrolled in 21 studies that evaluated nine treatment modalities: triamcinolone (TAC), 5-fluorouracil (5-FU), botulinum toxin type A (BTA), platelet-rich plasma (PRP), Verapamil, BTA+ 5-FU, TAC+ 5-FU, TAC+ BTA, and TAC+ PRP. The network diagram revealed that there were 36 pairwise comparisons among the 9 treatment measures, with direct comparisons in 13 of them. The funnel plot demonstrated a symmetrical distribution of effect size points, and both Beggs test and Eggers test yielded P values greater than 0.05, indicating a low likelihood of publication bias. Nine treatment measures formed five closed loops with good consistency. The result of the network meta-analysis indicated that BTA+ 5-FU was more effective than TAC, 5-FU, or PRP alone; TAC+ 5-FU was more effective than TAC, 5-FU, or PRP alone; TAC+ BTA was more effective than TAC, 5-FU, BTA, or PRP alone; Verapamil was more effective than 5-FU and BTA was more effective than 5-FU. All result were found to be statistically significant ( P<0.05). A surface under the cumulative ranking area (SUCRA) map was generated, displaying the efficacy ranking and corresponding SUCRA values for each treatment: BTA+ 5-FU (85.6%)>TAC+ 5-FU (84.8%)>BTA+ TAC (76.7%)>Verapamil (48.9%)>BTA (45.0%)>TAC+ PRP (43.8%)>PRP (32.1%)>TAC (24.7%)>5-FU(8.3%). In terms of recurrence rate, the incidence of recurrence was higher with 5-FU compared to BTA or TAC+ 5-FU, and the incidence of recurrence was higher with TAC compared to TAC+ 5-FU; these differences were statistically significant ( P<0.05). A SUCRA map was generated with the ranking and SUCRA value for each treatment as follows: 5-FU (80.4%)>TAC (73.5%)>Verapamil (65.7%)>TAC+ BTA (52.5%)>PRP (34.8%)>BTA+ 5-FU (33.7%)>TAC+ 5-FU (30.2%)>BTA (29.3%). The qualitative analysis revealed a significantly lower incidence of systemic and local adverse reactions following combined drug injection compared to single drug injection. Conclusion:In the treatment of keloids using drug injection, combination therapy utilizing multiple drugs has demonstrated superior efficacy, lower recurrence rates, and fewer adverse reactions in comparison to single-drug therapy. Notably, the utilization of BAT, 5-FU, and TAC in combination may yield the most favorable outcomes.
