Background/Aims: Metabolic dysfunction-associated steatohepatitis (MASH) is a significant risk factor for gallstone formation, but mechanisms underlying MASH-related gallstone formation remain unclear. Golgi membrane protein 1 (GOLM1) participates in hepatic cholesterol metabolism and is upregulated in MASH. Here, we aimed to explore the role of GOLM1 in MASH-related gallstone formation. Methods: The UK Biobank cohort was used for etiological analysis. GOLM1 knockout (GOLM1-/-) and wild-type (WT) mice were fed with a high-fat diet (HFD). Livers were excised for histology and immunohistochemistry analysis. Gallbladders were collected to calculate incidence of cholesterol gallstones (CGSs). Biles were collected for biliary lipid analysis. HepG2 cells were used to explore underlying mechanisms. Human liver samples were used for clinical validation. Results: MASH patients had a greater risk of cholelithiasis. All HFD-fed mice developed MASH, and the incidence of gallstones was 16.7% and 75.0% in GOLM1-/- and WT mice, respectively. GOLM1-/- decreased biliary cholesterol concentration and output. In vivo and in vitro assays confirmed that GOLM1 facilitated cholesterol efflux through upregulating ATP binding cassette transporter subfamily G member 5 (ABCG5). Mechanistically, GOLM1 translocated into nucleus to promote osteopontin (OPN) transcription, thus stimulating ABCG5-mediated cholesterol efflux. Moreover, GOLM1 was upregulated by interleukin-1β (IL-1β) in a dose-dependent manner. Finally, we confirmed that IL-1β, GOLM1, OPN, and ABCG5 were enhanced in livers of MASH patients with CGSs. Conclusions In MASH livers, upregulation of GOLM1 by IL-1β increases ABCG5-mediated cholesterol efflux in an OPN-dependent manner, promoting CGS formation. GOLM1 has the potential to be a molecular hub interconnecting MASH and CGSs.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

ObjectiveTo explore the effects of astragalin （AST） on autophagy and apoptosis of astrocytes in the L_4-5 dorsal horn of the spinal cord in mice with inflammatory pain induced by complete Freund's adjuvant （CFA）. MethodsTwenty-four male C57BL/6 mice， aged six months， were randomly assigned to four groups： control group， saline group， CFA model group， and CFA+AST group， six mice in each group. The inflammatory pain model was established by injection of 10 µL CFA into the right lateral malleolus fossa. The saline group were injected with an equal amount of normal saline at the same site. The inflammatory pain mice in CFA+AST group were further treated with AST （60 mg/kg） intraperitoneally once a day for 21 consecutive days. Multiplex immunofluorescence staining was used to detect the coexpression of autophagy-related factors including ATG 12 and Beclin-1， apoptosis-related factors including Cleaved-Caspase3 and Caspase9， and the astrocyte marker such as GFAP in the L_4-5 spinal dorsal horn of the mice in each group. Western blot was used to examine the protein expression levels of autophagy-related proteins（ATG12， Beclin-1） and apoptosis-related proteins（Caspase 3， Caspase 9） in the L_4-5 spinal dorsal horn of mice. ResultsImmunofluorescent staining showed that in the L_4-5 dorsal horn of the spinal cord， the fluorescence intensity of ATG12 （P<0.000 1） and Beclin-1 （P<0.000 1） was significantly increased， while that of Cleaved-Caspase 3 （P<0.001） and Caspase 9 （P<0.000 1） was decreased in the CFA+AST group when compared to the CFA model group. Furthermore， AST could inhibit the activation of astrocytes. Western blot further confirmed that AST significantly upregulated the expression of ATG12 （P<0.000 1） and Beclin-1 （P<0.000 1） in the L_4-5 spinal cord of CFA mice， and downregulated the expression of Caspase 3 （P<0.01） and Caspase 9 （P<0.001）. ConclusionsAST promotes autophagy of astrocytes and inhibits their apoptosis in the L_4-5 spinal dorsal horn of CFA mice.

Objective To retrospectively analyze the screening and prevalence trend of MTB/HIV（tuberculosis/human immunodeficiency virus） co-infection patients in Shaanxi Province from 2018 to 2022, and to provide scientific basis for further improving the prevention and control strategy of MTB/HIV co-infection in Shaanxi province. Methods Through annual reports and National Tuberculosis Information Management System of MTB/HIV co-infection, the screening, treatment and outcomes of MTB/HIV co-infected patients in Shaanxi Province from 2018 to 2022 were collected and analyzed． Results From 2018 to 2022, HIV antibodies were detected in 49 252 patients, with detection rate of 55.41%, and 57 patients of HIV infection were detected. During the same period, among HIV/AIDS patients, the screening rate of tuberculosis symptoms in newly detected HIV/AIDS patients was 95.91%, the detection rate of tuberculosis was 94.25%, and 174 MTB/HIV patients were found. The screening rate of tuberculosis symptoms in previously-recognized HIV/AIDS patients was 96.94%, the detection rate of tuberculosis was 95.45%, and 135 MTB/HIV patients were found. From 2018 to 2022, the overall trends of HIV detected in tuberculosis patients (χ2trend=4 589.301, P<0.05), screening of tuberculosis in newly detected and previous HIV (χ2trend=47.400, P<0.05; χ2trend=60.196, P<0.05), examination of tuberculosis in newly detected and previous HIV(χ2trend=755.856, P<0.05; χ2trend=526.498, P<0.05), were fluctuating and rising year by year. The screening rate, inspection rate and detection rate of newly detected and previous HIV in each year had statistical differences(P<0.05), except for the inspection rate in 2020 and 2022. Among the MTB/HIV patients, 336 (91.80%) were males, 30 (8.20%) were females. The anti tuberculosis treatment rate for all MTB/HIV patients was 89.62%, and the successful treatment rate for tuberculosis was 87.80%. Conclusion The quality of two-way screening and prevention work in Shaanxi Province is gradually improving. MTB patients have a higher detection rate in newly detected HIV/AIDS. Strengthening the screening of MTB in newly detected HIV/AIDS is beneficial to earlier found and treatment of MTB/HIV, improve the success rate of TB treatment and reduce the death rate of MTB/HIV patients.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.
