This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To analyze the clinical characteristics, imaging, myopathology and outcomes of patients with COVID-19 related autoimmune myopathy.Methods:The clinical features, serum creatine kinase (CK), myositis antibodies, muscle magnetic resonance imaging, myopathology and therapy of 5 patients with COVID-19 related autoimmune myopathy diagnosed in Peking University First Hospital from December 2022 to April 2023 were collected. The effects of the therapy after a short term follow up were analyzed.Results:Among the 5 patients, there were 3 males and 2 females, with onset age of 42-86 years. All patients presented with proximal muscle weakness in the recovery term of COVID-19. Myalgia was noted in 3 cases, dysphagia in 1, skin damage in 2, interstitial lung disease in 1. The serum CK of the 5 patients was 1 663-16 000 IU/L, 1 patient had anti-3-hydroxy-3-methylglutaryl-CoA reductase autoantibodies and 1 patient had anti-signal recognition particle autoantibodies. The electromyography showed myogenic lesions in all patients. Muscle magnetic resonance imaging showed diffuse muscle edema in all patients, myofascial edema in 3 and subcutaneous-tissue edema in 3. The muscle biopsies in 4 patients revealed necrotic myopathy,with high P62 expression in muscle fibers. The electromicroscopy of 2 patients revealed vacuolated mitochondria and intranuclear tubulofilamentous inclusions in muscle fibers. Four patients were treated with glucocorticoids, of whom 2 patients combined with intravenous immunoglobulin, tacrolimus or cyclophosphamide. One case had close monitoring without drug therapy. They showed significant improvement, but the CK was still abnormal in 4 patients.Conclusions:COVID-19 leads to immune mediated myopathy. The manifestation of patients is characterized by proximal predominant weakness and high creatine kinase level. Muscle magnetic resonance imaging shows diffuse muscle edema. The muscle biopsies reveal necrotic myopathy. The effectiveness of immunosuppression needs to be further studied.

Objective To investigate the serum tumor necrosis factor like weak inducer of apoptosis(TWE AK),sterol regulatory element-binding protein 1(SREBP-1)levels in patients with prostate cancer(PC)and their relationship with clinical pathological characteristics and progression free survival prognosis.Method A total of 94 PC patients who underwent PC radical surgery in Wuhan Dongxihu District People's Hospital from January 2018 to January 2020 were selected as the PC group.Meanwhile,50 patients with benign prostatic hyperplasia(BPH)during the same period were selected as the BPH group,and 50 healthy individuals who underwent physical examination during the same period were selected as the control group.Enzyme linked immunosorbent assay(ELISA)was used to detect the expression levels of serum TWEAK and SREBP-1.Kaplan-Meier survival analysis was used to analyze the effects of serum TWEAK and SREBP-1 on the progression free survival in prostate cancer patients.Multivariate COX regression analysis was used to analyze factors affecting the prognosis of progression free survival in prostate cancer patients.Results The serum TWEAK(77.14±15.46 ng/L)and SREBP-1(334.14±33.81 ng/L)levels in the PC group were higher than those in the BPH group(38.69±10.58 ng/L,201.69±28.74 ng/L)and control group(36.26±10.27 ng/L,189.51±27.65 ng/L),with significant differences(t=23.752,25.249;34.636,37.821,all P＜0.05).There was a positive correlation between serum TWEAK and SREBP-1 expression in PC patients(r=0.668,P=0.001).The serum TWEAK and SREBP-1 levels in PC patients with Gleason score＞7,TNM stage Ⅲ,and preoperative prostate specific antigen(PSA)level ≥ 20 ng/ml were higher than those with Gleason score≤7,TNM stage Ⅰ～Ⅱ,and preoperative PSA level＜20ng/ml,with significance differences(t=8.465～16.597,all P＜0.05).The 3-year overall progression free survival rates of the TWEAK high expression and low expression groups were 60.42％(29/48)and 86.96％(40/46),respectively.The 3-year overall progression free survival rates of the SREBP-1 high expression and low expression groups were 57.78％(26/45)and 87.76％(43/49),respectively.The 3-year cumulative progression free survival rates of the TWEAK high expression group and the SREBP-1 high expression group were lower than those of the TWEAK low expression group and the SREBP-1 low expression group,and the differences were significant(Log rankx2=8.125,9.547,P=0.004,0.002).TNM stage Ⅲ(OR=1.448,P＜0.001),Gleason score＞7(OR=1.401,P＜0.001),preoperative PSA ≥ 20 ng/ml(OR=1.353,P＜0.001),serum TWEAK(OR=1.338,P＜0.001),and SREBP-1(OR=1.293,P＜0.001)were independent risk factors affecting the progression free survival prognosis of PC patients.Conclusion Serum TWEAK and SREBP-1 in prostate cancer patients were increased,and they were correlated with the clinical pathological characteristics of PC.They could be serum biomarkers for evaluating the prognosis of progression free survival.

Objective:To compare the safety of radial artery puncture in elderly patients aged 75 years and older who are undergoing neurointerventional procedures.Methods:A single-center retrospective study was conducted, involving 350 elderly patients aged 75 years and older who received neurointerventional treatment at Beijing Tiantan Hospital, Capital Medical University, from June to December 2022.The participants were divided into two groups based on the puncture site: femoral artery puncture and radial artery puncture.The safety indicators compared between the two groups included puncture failure, changes in puncture site, general puncture complications(such as subcutaneous bleeding, puncture site hematoma, and vasospasm), severe puncture complications(including distal limb ischemia and pseudoaneurysm), and lower limb venous thrombosis.Multivariate Logistic regression analysis was conducted to evaluate the impact of different puncture methods on the occurrence of complications.Results:Among the 350 patients, 280 underwent femoral artery puncture, while 70 underwent radial artery puncture.There were no statistically significant differences in baseline characteristics between the two groups(all P>0.05).The proportions of patients using antiplatelet drugs prior to surgery, puncture failure rates, rates of change in puncture sites, and the incidence of severe complications-including distal limb ischemia and pseudoaneurysm-were not significantly different between the two groups( χ2=2.051, 0.075, 0.588, 3.175; P=0.152, 0.784, 0.443, 0.075).In the femoral artery puncture group, 20.4%(57 cases)of patients experienced general puncture complications(including subcutaneous bleeding, puncture site hematoma, and vasospasm), whereas only 8.6%(6 cases)in the radial artery puncture group experienced such complications, revealing a statistically significant difference between the two groups( χ2=5.720, P=0.022).Multivariate Logistic regression analysis indicated that, compared to femoral artery puncture, radial artery puncture was associated with a reduced risk of all complications( OR=0.272, 95% CI: 0.139-0.532, P<0.001), general puncture complications( OR=0.375, 95% CI: 0.153-0.919, P=0.032)and lower limb venous thrombosis( OR=0.219, 95% CI: 0.050-0.954, P=0.043). Conclusions:In elderly patients aged 75 years and older who are undergoing neurointerventional procedures, radial artery puncture is associated with a reduced incidence of general puncture complications and lower limb venous thrombosis when compared to femoral artery puncture, indicating a superior safety profile.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Objective To investigate the relationships of preoperative serum V-set and immunoglobulin domain 4 (VSIG4) and long chain non-coding ribonucleic acid (LncRNA) SBF2 antisense RNA1 (SBF2-AS1) with acute kidneyinjury (AKI) after percutaneous nephrolithotomy in patients with renal calculus. Methods A total of 109 patients with renal calculus in the hospital from January 2020 to December 2022 were selected as research objects. Serum VSIG4 level and LncRNA SBF2-AS1 expression were detected in all the patients before operation, and incidence of AKI was recorded after operation. Multiple Logistic regression model was used to analyze the factors affecting AKI after percutaneous nephrolithotomy in patients with renal calculus; the receiver operating characteristic (ROC) curve was used to analyze the values of VSIG4 and LncRNA SBF2-AS1 in predicting AKI after percutaneous nephrolithotomy in patients with renal calculus. Results In this study, 16 cases had AKI after operation. The serum VSIG4 level in the AKI group was significantly lower than that in the non-AKI group, while the LncRNA SBF2-AS1 expression was significantly higher than that in the non-AKI group (P < 0.05). Multivariate Logistic regression analysis showed that preoperative high level of uric acid, preoperative high expression of LncRNA SBF2-AS1, the longer operation time and intraoperative hypotension were the risk factors for AKI after percutaneous nephrolithotomy in patients with renal calculus (P < 0.05), while preoperative high level of VSIG4 was the protective factor (P < 0.05). The values of area under the curve of preoperative serum VSIG4 and LncRNA SBF2-AS1 in predicting AKI after percutaneous nephrolithotomy in patients with renal calculus were 0.854 and 0.705 respectively, and the area under the curve of combined prediction of the two indexes was 0.948, which was significantly higher than that of single index prediction (Z=1.995, 2.958, P < 0.05). Conclusion Decreased preoperative serum VSIG4 level and increased expression of LncRNA SBF2-AS1 in patients with renal calculus are associated with the occurrence of AKI after percutaneous nephrolithotomy, and the combined detection of preoperative VSIG4 and LncRNA SBF2-AS1 can predict the risk of AKI after operation.

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease, the cause is not yet clear. Pathological manifestations are abnormal repair changes resulting from sustained lung injury. Macrophages have been identified as playing a key role in IPF pathogenesis. In different local microenvironments, macrophages can exhibit either classically activated (M1) or alternately activated (M2) phenotypes. M1 plays a key role in promoting inflammatory response and is involved in the process of causing alveolar tissue injury. M2 is involved in wound healing and stopping lung inflammation. Previous studies have shown that activation of 5-hydroxytryptamine (5-HT) signaling is enhanced in pulmonary fibrosis and that 5-HT receptors play an important role in the observed pro-fibrotic effects. As a multifunctional signaling molecule, 5-HT is closely related to lung macrophage polarization, early lung tissue injury, abnormal proliferation and repair, and late extracellular matrix (ECM) deposition. This article reviewed the role of 5-HT and M2 macrophages in the pathogenesis of IPF and the possible regulatory mechanism of 5-HT, in order to provide a reference for further research.

Objective:To assess the predictive performance of the risk of cardiovascular diseases (CVD) derived from the China Kadoorie Biobank (CKB-CVD) model, prediction for atherosclerotic cardiovascular disease (ASCVD) risk in China (China-PAR) model, and the risk of fatal and nonfatal ischemic cardiovascular diseases derived from the USA-People′s Republic of China Collaborative Study (USA-PRC) model in Chinese Multi-provincial Cohort Study (CMCS).Methods:In this prospective cohort study, a total of 21 948 individuals aged ≥35 years without CVD were selected from 8 provinces and cities in China during the CMCS survey from 1992 to 2005 for 10-year follow-up. The occurrence of CVD or ASCVD events during the follow-up period was used as the gold standard. The CKB-CVD and China-PAR models were used to calculate the predicted risk of CVD events, while the USA-PRC model was used to calculate the predicted risk of ASCVD events. The discrimination of the models was evaluated using the C-statistic, and the calibration was assessed using the Hosmer-Lemeshow χ2 test and decile plot. Results:During the 10-year follow-up, a total of 955 (4.4%) CVD events, including 791 (3.6%) ASCVD events, were recorded among the study participants. The C-index for the CKB-CVD, China-PAR, and USA-PRC models were 0.775 (95% CI: 0.757-0.793), 0.781 (95% CI: 0.763-0.798), and 0.769 (95% CI: 0.750-0.789) for men, and 0.762 (95% CI: 0.737-0.788), 0.769 (95% CI: 0.745-0.794), and 0.767 (95% CI: 0.741-0.794) for women, respectively. China-PAR model showed good calibration for men ( χ2=2.20), however, both CKB-CVD and USA-PRC models demonstrated poor calibration in both men and women ( χ2>20). The results indicated that the CKB-CVD model overestimated the risk of CVD events in both males and females, while the China-PAR model underestimated the risk in females. Furthermore, the USA-PRC model underestimated the risk of ASCVD in both males and females in most decile groups, but overestimated the risk in the highest decile group. Conclusion:The CKB-CVD, China-PAR, and USA-PRC risk assessment models show some degree of deviation from the actual risk of events in the CMCS cohort, but all exhibit good discrimination.
