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 identify signals of adverse events associated with vaccines in electronic medical record data. Methods Data cleaning was performed on electronic medical records and vaccination data in Gansu Province from 2020 to 2022. Signal identification was performed using Apriori algorithm and Empirical Bayes Gamma-Poisson Shrinker (GPS) with stratification by gender and age group. Results A total of 33 statistical signals were identified, with 7 signals identified by the Apriori method and 26 signals identified by the GPS method. No overlapping signals were found between the two methods at two different signal thresholds. Conclusion The vaccine safety signals identified by GPS and Apriori in electronic medical records are reliable and accurate, but further research is needed to determine the correlation between the vaccine safety signals recognized by GPS algorithms.

【Objective】 To study the relationship between ABO subtype, para-Bombay blood group and genotype, so as to explore the possible molecular mechanism of these two blood groups, and provide accurate genetic detection targets and theoretical basis for the accurate identification of ABO blood group. 【Methods】 First, the serology of 24 200 patients with blood type identification in the Ruijin Hospital from February to December in 2022 were analyzed, as well as 10 ambiguous ABO samples from other hospitals(3 were suspected ABO subtype and 7 were suspected para-Bombay blood group). Then ABO subtypes and para-Bombay blood groups were directly sequenced or post-clonal sequencing was performed to analyze ABO, FUT1 and FUT2 gene sequences. 【Results】 Among the 24 200 patients underwent blood type identification, 7 cases of ABO subtypes were detected. Among the 10 ambiguous samples sent by other hospitals, 2 of ABO subtypes, 1 of normal type A, and 7 of para-Bombay blood type were detected. In total, we identified blood types as follows: 1) 9 ABO subtypes: Ael(AEL.02/O.01.02), AelB(AEL.05/B.01), three of B3(2 of B3.03/O.01.01, 1 of B3.03/O.01.02), B(A)(BA.02/O.01.01), ABweak(A1.02/BW.07), Bweak(BW.31 /O.01.02), A2Bweak(A2.05 /BW.31); 2) 7 para-Bombay blood group: ABm^h (FUT1^*01N.13/FUT1^*01N.13), 4 of Am^h (3 of FUT1^*01N.06/FUT1^*01N.13, 1 of FUT1^*01N.13/FUT1^*01N.13); two of Bm^h (FUT1^*01N.06 /FUT1^*01N.06, FUT1^*01N.06/FUT1^*01N.13), all of FUT2 of the 7 cases were FUT2^*01/FUT2^*01. 【Conclusion】 Clinical ABO blood group variant samples need to be identified in combination with serological and molecular biology to improve the accuracy of identification, thus providing a reference for safe blood transfusion, organ transplantation, and the prediction and prevention of fetal-maternal immune hemolytic disease.

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.

The "brain electric field" therapy is a novel electroacupuncture method created by Professor GAO Weibin to treat cerebral infarction in the recovery period. This therapy is suitable for the treatment of motor disorders, sensory disorders, cognitive disorders, hemianopsia and bulbar paralysis during the recovery period of cerebral infarction. Based on the different symptoms, the corresponding brain functional areas are selected, supplemented with Taiyang 2, Tunyan 2, Tiyan, Gongxue and Xiatianzhu. These points are attached to electric acupuncture apparatus, and stimulated with dense wave, at frequency of 50 Hz and tolerable intensity. This therapy presents a remarkable effect on cerebral infarction in the recovery period, providing the new approach to the treatment of this disease.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.

Background::Hepatopancreatoduodenectomy (HPD) has been considered the only curative treatment for metastatic cholangiocarcinoma and some locally advanced gallbladder cancers (GBCs). However, HPD has not yet been included in treatment guidelines as a standard surgical procedure in consideration of its morbidity and mortality rates. The aim of this study was to evaluate the safety and effectiveness of HPD in treating biliary malignancies.Methods::The medical records of 57 patients with advanced biliary cancer undergoing HPD from January 2009 to December 2019 were retrospectively retrieved. A case-control analysis was conducted at our department. Patients with advanced GBC who underwent HPD (HPD-GBC group) were compared with a control group (None-HPD-GBC group). Baseline characteristics, preoperative treatments, tumor pathologic features, operative results, and prognosis were assessed.Results::Thirteen patients with cholangiocarcinoma and 44 patients with GBC underwent HPD at our department. Significant postoperative complications (grade III or greater) and postoperative pancreatic fistula were observed in 24 (42.1%) and 15 (26.3%) patients, respectively. One postoperative death occurred in the present study. Overall survival (OS) was longer in patients with advanced cholangiocarcinoma than in those with GBC (median survival time [MST], 31 months vs. 11 months; P < 0.001). In the subgroup analysis of patients with advanced GBC, multivariate analysis demonstrated that T4 stage tumors ( P = 0.012), N2 tumors ( P = 0.001), and positive margin status ( P = 0.004) were independently associated with poorer OS. Patients with either one or more prognostic factors exhibited a shorter MST than patients without those prognostic factors ( P < 0.001). Conclusion::HPD could be performed with a relatively low mortality rate and an acceptable morbidity rate in an experienced high-volume center. For patients with advanced GBC without an N2 or T4 tumor, HPD can be a preferable treatment option.
