Objective To investigate the pharmacological effects of"Yajieshaba"on mice with alcohol-induced liver injury and to investigate the mechanism of the impact of"Yajieshaba"on the regulation of intestinal flora by 16S rDNA technology.Methods Healthy male KM mice were randomly divided into control,model,"Yajieshaba"low,medium,and high dose(0.39,1.17 and 3.51 g·kg-1)groups and Bifendatatum(2.93 mg·kg-1)groups,with eight mice in each group.After one week of pre-administration of"Yajieshaba",a mouse model of acute alcoholic liver injury was established by a single instillation of 56%alcohol,and the levels of AST and ALT in the serum of mice were measured,and the morphological changes of liver histology were observed by HE staining;secondly,faecal DNA was extracted from each group under aseptic operation,and 16S rDNA sequencing and differential analysis by alpha diversity and species composition at the phylum and genus levels were performed.Results The results showed that the biochemical indexes of liver function(ALT and AST)were significantly improved by"Yajieshaba",and the degree of liver damage was significantly reduced by HE staining.At the phylum level,it significantly decreased the abundance of Aspergillus and increased the quantity of Bacteroides;at the genus level,it significantly up-regulated the plenty of Bacteroides and Prevotella and downregulated a lot of Prevotella and Helicobacter.At the genus level,"Yajieshaba"significantly up-regulated the abundance of Bacillus spp.and Prevotella spp.and down-regulated the abundance of Prevotella spp.and Helicobacter spp.Conclusion"Yajieshaba"may play an anti-acute alcoholic liver injury effect by regulating the intestinal flora and metabolites.

Objective:To evaluate the safety and efficacy of enhanced recovery after surgery(ERAS) in the perioperative period of congenital choledochal cysts in children.Methods:This is a multicenter prospective randomized controlled study. The clinical data of 273 pediatric congenital choledochal cysts(CCC) patients who underwent surgery at 14 medical centers with complete follow-up data were collected through the medical data analysis platform. Among them, 123 cases in ERAS group were managed perioperatively in strict accordance with ERAS mode, and 150 cases in conventional group were managed according to traditional mode. The length of hospital stay,time to first farting, time to complete feeding, the incidence of complications, cost and readmission rate within 30 days,stress indexes and liver function were compared between the two groups.Results:Compared with the conventional group, median time to start farting (2.0 d vs. 3.0 d, P<0.001), median time to complete feeding (5.0 d vs. 7.0 d, P<0.001), median postoperative hospitalization time (6.0 d vs. 9.0 d, P<0.001),the median total length of stay(13.0 d vs. 15.0 d, P<0.001) were shorter,the median hospitalization cost (37,000 yuan vs.43,000 yuan P<0.001) was lower, and stress indexes recovered quickly. The incidence of postoperative hospital stay and readimission rate within 30 d were not statistically different between the two groups. Conclusion:It is safe and feasible to implement ERAS for children with CCC in the perioperative period, which can reduce stress response, speed up recovery,and save medical costs.
