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.

Parkinson's disease(PD)is a common progressive neurodegenerative disease mainly affecting the motor system.Various genetic factors and cellular mechanisms underlying PD have recently been discovered.Emerging evidence suggests that epigenetic modifications play a very important role in the pathogenesis,prevention,and treatment of PD.Epigenetic modification mediates genetic and environmental interactions mainly through complex interactions of DNA methylation,histone modification,and non-coding RNA,thereby affecting expression in the absence of changes in DNA sequence.In this review,we summarize the epigenetic modification mechanisms involved in the pathogenesis of Parkinson's disease.In this review,we summarize the epigenetic modification mechanisms involved in the pathogenesis of Parkinson's disease.Recent studies have found that traditional Chinese medicine can participate in the regulation of abnormal epigenetic modifications in the treatment of PD.Traditional Chinese medicine benefits from its multi-level and multi-target regulatory effects,and various traditional Chinese medicine monomers,compound prescriptions,and techniques have been evaluated,confirming that this is a promising approach for improving symptoms in PD.This review summarizes the mechanisms by which epigenetic modifications contribute to P D,explores the role of traditional Chinese medicine,and provides new ideas for clinical treatment and drug development in PD through epigenetic intervention.

The glymphatic system is a recently discovered essential waste-clearance pathway in the central nervous system that plays a pivotal role in maintaining brain homeostasis.Growing evidence suggests that dysfunction of this system is closely associated with the pathogenesis of various neurodegenerative disorders;however,its precise mechanistic involvement in Parkinson's disease is poorly understood.This review systematically summarizes the structural and functional characteristics of the glymphatic system,provides an in-depth exploration of its potential role in Parkinson's disease pathophysiology,and synthesizes current research evidence on glymphatic system-targeted therapeutic strategies,with the aim of establishing a theoretical foundation for advancing the understanding of PD pathogenesis and developing novel diagnostic and therapeutic approaches.

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 levels of microRNA (miR) -106b-5p and miR-760 in the serum of early lung cancer patients, and the clinical value of the combination of them and low-dose spiral CT in the diagnosis of early lung cancer.Methods:Ninety early lung cancer patients (lung cancer group) who underwent treatment in Cangzhou People's Hospital of Hebei Province from January 2022 to March 2023 were collected as research subjects, meantime, 90 patients with benign pulmonary lesions (benign pulmonary nodules) diagnosed by pathology were selected as the control group. The levels of miR-106b-5p and miR-760 in the serum of two groups were compared, the results of low-dose spiral CT examination were analyzed; receiver operating characteristic curve was drawn to determine the optimal cut-off values of serum miR-106b-5p and miR-760; four grid table method was applied to analyze the diagnostic efficacy of serum miR-106b-5p, miR-760 combined with low-dose spiral CT for early lung cancer.Results:The level of miR-106b-5p in lung cancer group was higher than that in control group (1.39±0.31 vs. 1.04±0.30), serum miR-760 level was lower than that in control group (0.75±0.24 vs. 1.02±0.26), with statistically significant differences ( t=7.70, P<0.001; t=7.24, P<0.001). The area under curve (AUC) of miR-106b-5p, miR-760 and low-dose spiral CT in the diagnosis of early lung cancer was 0.83, 0.81 and 0.82, the accuracy was 76.67%, 77.22% and 81.67%, the sensitivity was 84.44%, 81.11% and 76.67%, and the specificity was 68.89%, 73.33% and 86.67%, respectively. The AUC, accuracy, sensitivity, and specificity of serum miR-106b-5p, miR-760 combined with low-dose spiral CT in diagnosing early lung cancer were 0.96, 90.00%, 94.44%, and 85.56%, respectively. The accuracy of the three combined diagnosis was higher than that of individual diagnosis of miR-106b-5p, miR-760 and low-dose spiral CT ( χ2=11.52, P=0.001; χ2=10.72, P=0.001; χ2=5.14, P=0.023), the sensitivity of the three combined diagnosis was higher than that of individual diagnosis of miR-106b-5p, miR-760 and low-dose spiral CT ( χ2=4.77, P=0.029; χ2=7.46, P=0.006; χ2=11.51, P=0.001), the specificity of the three combined diagnosis was higher than that of individual diagnosis of miR-106b-5p, miR-760 ( χ2=7.11, P=0.008; χ2=4.12, P=0.042) . Conclusion:The serum level of miR-106b-5p is significantly increased in early lung cancer patients, while the serum level of miR-760 is significantly reduced. The combination of miR-106b-5p, miR-760 and low-dose spiral CT has high diagnostic value for early lung cancer.

Objective:To analyze the clinical effects of intraoperative transesophageal echocardio-graphy(TEE)in different surgical methods for nephrectomy combined with Mayo Ⅲ-Ⅳ inferior vena cave(IVC)tumor thrombectomy.Methods:In the study,28 patients who did surgery of nephrectomy and Mayo Ⅲ-Ⅳ IVC thrombectomys in Peking University Third Hospital from 2022 January to 2024 February were included.Of the 28 patients,16 patients did robotic surgery,2 patients did laparoscopic surgery,and 10 patients did open surgery.All patients'clinical data were collected.Results:Intra-operative TEE was used in 9 robotic surgeries,of which 7 cases showed image changes compared with preoperative image results.Intraoperative TEE indicated that tumor thrombus entered the right atrium in 2 cases,showed that tumor thrombus grade rose from Mayo Ⅲ to Mayo Ⅳ in 2 cases,and indicated that tumor thrombus adhered to IC wall in 3 cases.All of these surgical plans were timely adjusted.Intra-operative TEE was used in 6 cases of open surgery,and 4 cases of them showed Mayo grade changes com-pared with preoperative image results.Intraoperative TEE indicated that tumor thrombus adhered to the IVC wall in 3 cases,and tumor thrombus adhered to the IVC wall with thrombus in one case.The surgi-cal plans were adjusted,and the tumor thrombus was left or segmentally removed.Laparoscopic surgery did not use intraoperative TEE.The effects of intraoperative TEE included:the combination of explora-tion and TEE monitoring was used in open surgery,and tumor thrombus removal process was fully moni-tored by intraoperative TEE in the robotic surgery.Intraoperative TEE real-time monitored circulatory sta-tus and cardiac function changes.Conclusion:In different surgical methods for nephrectomy com-bined with Mayo Ⅲ-Ⅳ tumor thrombectomy,intraoperative TEE can re-determine the tumor thrombus grade and degree of tumor thrombus adhered to IVC,track the tumor thrombus removal process in real-time,and monitor circulatory status and cardiac function changes.Intraoperative TEE plays an important role in different surgical methods,but its clinical application is still insufficient.Intraoperative TEE is recommended to such type of surgeries.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.
