ObjectiveTo discuss the effects of Cistanches Herba phenylethanoid glycosides (CHPhGs) on the intestinal mucosal barrier and gut microbiota in alcoholic liver disease (ALD) mice were discussed. MethodThe 36 C57BL/6N female mice were randomly divided normal group, normal group of CHPhGs, model group, and low, medium, and high-dose groups (175, 350, 700 mg·kg-1) of CHPhGs, with six mice in each group. The ALD mouse model was built using Lieber-Decarli alcohol liquid feed. The normal group and low, medium, and high-dose groups of CHPhGs were given CHPhGs by gavage daily. Serum aspartate aminotransferase aminotransferase (ALT), alanine aminotransferase (AST), triglycerides (TG), and total cholesterol (TC) levels were detected by an automatic biochemical analyzer. Serum tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), lipopolysaccharide (LPS), lipopolysaccharide-binding protein (LBP), D-lactic acid (D-LA), diamine oxidase (DAO), and LBP of liver were detected by enzyme-linked immunosorbent assay (ELISA). The levels of TG and TC in the liver were detected by colorimetry. Liver tissue was treated by oil red O and hematoxylin-eosin (HE) staining. The microstructure of jejunum epithelial cells was observed by electron microscope. Jejunum and colon were treated by HE staining and alcian blue-periodate-scheff (AB-PAS) staining staining, and mucin 2 (Muc2) was treated by immunohistochemistry. The intestinal contents of the normal group, normal group of CHPhGs, model group, and high-dose group of CHPhGs were collected and sequenced. ResultThe ALD model was established successfully. Compared with the normal group, the levels of serum ALT, AST, and TG, as well as the levels of liver TG and TC in the model group were significantly increased (P<0.05). Histopathology showed that compared with the normal group, the liver cells in the model group showed obvious steatosis. Compared with the model group, the levels of serum TG and liver TG and TC in the low, medium, and high-dose groups of CHPhGs decreased significantly (P<0.05). The serum ALT, AST, TNF-α, IL-1β, LPS, and LBP in the high-dose group of CHPhGs were also significantly decreased (P<0.05). The number of liver cells with steatosis in the high-dose group of CHPhGs was significantly reduced, and the microvilli structure of jejunum epithelial cells was basically intact. The expression of Muc2 was reduced in the colon, and the gut microbiota of the high-dose group of CHPhGs changed significantly (P<0.05). Compared with the normal group, the Allobaculum was significantly up-regulated in the model group (P<0.05). Compared with the model group, the abundance of Akkermansia in the high-dose group of CHPhGs was significantly increased (P<0.01). The abundance of Akkermansia was negatively correlated with that of Allobaculum (r=-0.701, P<0.01). ConclusionCHPhGs can reduce the intestinal barrier injury caused by ALD, which may play a protective role by regulating the abundance and structure of Akkermansia and Allobaculum and affecting the homeostasis of intestinal mucus.

ObjectiveTo investigate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in the treatment of difficult choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 12 patients with difficult choledocholithiasis who underwent ERCP and electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in Department of Gastroenterology, Jilin People’s Hospital, from May to November 2022. The clinical effect of lithotripsy and lithotomy was observed, and postoperative complications and time of surgical operation were assessed. ResultsAmong the 12 patients, 11 (91.67%) were successfully treated by electrohydraulic lithotripsy under direct view, 9 (75.00%) achieved first-attempt success in lithotripsy, and 11 (91.67%) had complete removal of calculi; 1 patient was found to have stenosis of the bile ducts caused by multiple biliary tract surgeries, and grade Ⅱ intrahepatic bile duct stones above the sites of stenosis were removed under direct view, but there were still residues of grade Ⅲ intrahepatic bile duct stones, which led to the fact that complete calculus removal was not achieved. The mean time of ERCP operation was 91.3±26.2 minutes, including a time of 41.8±22.2 minutes for energy lithotripsy. There were 2 cases of postoperative biliary tract infection which were improved after anti-infective therapy, 2 cases of hyperamylasemia which were not given special treatment, and 3 cases of mild pancreatitis which were improved after symptomatic medication, and there were no complications such as bleeding and perforation. ConclusionERCP combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system is safe, effective, and feasible in the treatment of difficult choledocholithiasis.

Background The high-pressure and high-risk nature of the police profession may consume individual resources and lead to job burnout. Objective To understand the current situation of police job burnout, and test potential mediating role of psychological empowerment between social support and job burnout. Methods From May to October 2020, a questionnaire survey was conducted among police officers in cities A and B of Sichuan Province by convenience sampling. The Perceived Social Support Scale, Psychological Empowerment Scale, and Maslach Burnout Inventory-General Survey were used to evaluate social support, psychological empowerment, and job burnout respectively. Mediation effect of psychological empowerment on the relationship between social support and job burnout was tested using bias-corrected bootstrap method. Results Of the 483 questionnaires recovered, there were 461 valid questionnaires (95.44%). The M (P25, P75) scores of social support, psychological empowerment, and job burnout were 5.00 (3.50, 5.83), 3.25 (2.00, 4.25), and 3.61 (2.43, 3.88), respectively. The positive rate of job burnout was 93.92% (433/461), of which 42.51% (196/461) and 51.41% (237/461) of the participants were at mild to moderate and severe levels of job burnout respectively. The results of Spearman correlation analysis showed that social support and psychological empowerment were negatively correlated with job burnout (r=−0.265, −0.328, P<0.01), and social support was positively corrected with psychological empowerment (r=0.390, P<0.01). The Bootstrap test results showed that social support negatively affected job burnout (β=−0.193, P<0.001) and positively affected psychological empowerment (β=0.330, P<0.001). Psychological empowerment negatively affected job burnout (β=−0.212, P<0.001) and played a partial mediating role in the relationship between social support and job burnout, and the effect value was −0.070 (95%CI: −0.097, −0.047) that accounted for 36.27% of the total effect. Conclusion Job burnout is prevalent among the police officers. Social support has a negative effect on job burnout, and psychological empowerment plays a partial mediating role between social support and job burnout.

Objective:To explore the effect of triglyceride glucose(TyG) index, single nucleotide polymorphism of Toll-like receptor 4(TLR4) and NOD-like receptor thermal protein domain associated protein 3(NLRP3) genes, and its interaction on the risk of gout.Methods:A total of 315 male patients with gout and 499 men for health checkup at the same period were selected. General data were collected through questionnaires, and peripheral venous blood was collected for biochemical test. Three single nucleotide polymorphisms(SNPs) of NLRP3 and TLR4 were detected with multiplex ligase assay reaction, and logistic regression analysis was applied to compare the correlation between NLRP3 and TLR4 alleles and gout risk. The interaction of SNP and TyG index with gout was analyzed by generalized multi-factor dimensionality reduction(GMDR) model and logistic regression.Results:After adjusting for smoking, drinking, and other factors, the risk of gout increased by 61.1% for each standard deviation increase in TyG index. CC genotypes of rs10754558, rs10759932, and rs7525979 were high risk genotypes of gout in Han ethnicity. GMDR results showed significant differences in the interaction models of rs10754558-TyG index, rs7525979-TyG index, and rs10759932-TyG index between control group and gout group( P<0.05), suggesting an interaction between the three genotypes of SNPs selected and TyG index. Stratified analysis of the three selected SNPs and TyG index showed that after adjusting for age, smoking, and other factors, the high TyG index patients carrying C/C or C/G genotype at rs10754558 displayed an increased risk of gout compared with those carrying GG genotype and low TyG index( OR=2.127, P<0.05). Conclusion:The CC genotypes of rs10754558, rs10759932, and rs7525979 are high risk genotypes for gout in Han ethnicity. The interaction between rs10754558 and TyG index may increase the risk of gout development.

Objective:To investigate whether stress hyperglycemia (SH) is an independent risk factor for the occurrence and mortality of sepsis-associated encephalopathy (SAE).Methods:From August 2016 to October 2021, sepsis patients admitted to the ICU of Guangdong Provincial People's Hospital were selected as the study subjects. According to whether they developed to SH (RBG>11.1 mmol/L) within 7 days of enrollment, the pat ients were divided into the SH group and the non-SH group for analysis. Logistic regression was used to analyze whether SH was an independent risk factor for SAE occurrence, and ROC curve was used to analyze the predictive value of SH to SAE. Kaplan-Meier curve was used to compare the 90-day survival of SAE patients with or without SH. Cox regression analysis was used to analyze the risk factors of 28-day and 90-day death in SAE patients.Results:A total of 183 sepsis patients were included, including 62 patients in the SH group and 121 in the non-SH group. Logistic regression analysis demonstrated that SH was an independent risk factor for SAE ( OR=4.452, 95% CI: 2.021-9.808, P <0.001). ROC curve demonstrated that SH could accurately predict SAE (AUC=0.831; Sensitivity=78.4%; Specificity=76.8%; and Yoden index=0.553). Kaplan-Meier curve demonstrated that the 90-day survival of SAE patients with SH significantly declined (log-rank test: P<0.01). Cox regression analysis suggested that SH was a risk factor for death at day 28 and day 90 in SAE patients (28 d, HR=2.272, 95% CI: 1.212-4.260, P=0.010; 90 d, HR=2.456, 95% CI: 1.400-4.306, P<0.01). Conclusions:SH is an independent risk factor for SAE and can predict SAE occurrence. SH significantly reduces 90-day survival and increase mortality at 28 and 90 days in SAE patients.

Anatomical right superior segmentectomy has always been a difficult surgical procedure in laparoscopic liver resection. How to accurately judge the interface between liver segments, so as to achieve a true sense of anatomic resection based on portal territory is a new requirement in the era of precision liver surgery. The portal vein puncture and indocyanine green (ICG) fluorescence positive staining technique can effectively solve this problem, which has a series of advantages and certain technical requirements in anatomical right superior segmentectomy. ICG fluorescence staining can intuitively define the three-dimensional range of the liver segment, which is a more accurate navigation mode that helps liver surgeons identify the range of the right superior liver segment, thus conducting surgery more safely and normatively. The authors consult relevant studies and combined with clinical practice to explore the application value of laparoscopic ultrosound guided puncture and positive staining technique in anatomical right superior segmentectomy.
