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 study the effects of dual-hemispheric transcranial direct current stimulation(Dual-tDCS)on upper limb motor function in chronic-phase stroke patients to provide theoretical references for neural mechanisms-based treatment of upper limb dysfunction.Methods Totally 24 chronic-phase stroke patients with upper limb motor dysfunction were selected from some hospital and divided into an experimental group(n=13)and a control group(n=11)the random number table.The control group was treated with tDCS pseudo-stimulation combined with conventional rehabilitation,while the experimental group was given with Dual-tDCS combined with conventional rehabilitation.The patient activities were assessed before and after treatment with Fugl-Meyer assessment upper limb scale(FMA-UL)and activities of daily living(ADL)scale.The changes of primary motor cortex(M1 area)and whole brain functional connectivity(FC)were compared before and after treatment.SPSS 24.0 statistical software was used for data analysis.Results After treatment,the two groups both had the FAM-UL and ADL scores increased significantly,and the experimental group had the scores statistically higher than those of the control group,and the differences were all statistically significant(P＜0.05).In the control group,the analysis on M1 area and whole brain FC after treatment indicated the FC decreased from M1 area at the unaffected side to midoccipital gyrus at the affected side and lingual gyrus and healthy angular gyrus at the unaffected side;there were no brain areas with changed FC found(P＜0.01).In the experimental group,the FC was lowered from M1 area at the unaffected side to cerebellum and cerebellar vermis at the unaffected side,while raised to precentral gyrus at the affected side(P＜0.01);the FC ascended from M1 area at the affected side to cerebellum and middle temporal gyrus at the affected side,while declined to precentral gyrus at the unaffected side(P＜0.01).Conclusion The neuromodulatory effect of Dual-tDCS on the brain improves FC in motor and non-motor-related brain areas in chronic-phase stroke patients,and may contribute to rehabilitation of upper limb motor dysfunction in chronic-phase stroke.[Chinese Medical Equipment Journal,2024,45(2):67-73]

Human brain banks use a standardized protocol to collect,process and store post-mortem human brains and related tissues,along with relevant clinical information,and to provide the tissue samples and data as a resource to foster neuroscience research according to a standardized operating protocols(SOP).Human brain bank serves as the foundation for neuroscience research and the diagnosis of neurological disorders,highlighting the crucial rule of ensuring the consistency of standardized quality for brain tissue samples.The first version of SOP in 2017 was published by the China Human Brain Bank Consortium.As members increases from different regions in China,a revised SOP was drafted by experts from the China Human Brain Bank Consortium to meet the growing demands for neuroscience research.The revised SOP places a strong emphasis on ethical standards,incorporates neuropathological evaluation of brain regions,and provides clarity on spinal cord sampling and pathological assessment.Notable enhancements in this updated version of the SOP include reinforced ethical guidelines,inclusion of matching controls in recruitment,and expansion of brain regions to be sampled for neuropathological evaluation.

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 clinical characteristics and interventions associated with drug-induced anaphylaxis in the emergency infusion room.Methods:Bases on the adverse drug reaction database from the emergency medicine center of the First Affiliated Hospital of Nanjing Medical University, clinical data of patients who experienced drug-induced anaphylaxis in the emergency infusion room between November 2019 and November 2023 were collected, including gender, age, history of previous adverse drug reactions, allergy history, Charlson comorbidity index, medication details, information related to drug-induced anaphylaxis (onset time, clinical manifestations), interventions, outcomes, and follow-up. The clinical characteristics and interventions in these patients were analyzed.Results:During the study period, a total of 398 772 patients in the emergency infusion room in our hospital received intravenous infusion of drugs. Of them, 625 cases developed adverse drug reactions (ADRs) and 75 cases developed drug-induced anaphylaxis, accounting for 0.02% (75/398 772) of the total infusion patients and 12.0% (75/625) of all ADR cases. Of the 75 patients with anaphylaxis, 30 cases (40%) were classified as grade Ⅱ, and 45 cases (60%) as grade Ⅲ, with no grade Ⅳ cases. The most common drugs involved in 75 cases of anaphylaxis were anti-infective drugs (41 cases, 54.7%). Drug-induced anaphylaxis exhibited diverse clinical manifestations, with cardiovascular symptoms being the most common, primarily varying degrees of transient hypotension (67 cases, 89.3%), followed by systemic and neurological symptoms, including profuse sweating (31 cases, 41.3%) and dizziness (28 cases, 37.3%). All 75 patients with anaphylaxis were treated with measures such as discontinuation of medication, replacement of infusion sets, rapid assessment of circulation and respiration, and monitoring of vital signs, of which 65 (86.7%) received rapid intravenous infusion for volume expansion, 6 (8.0%) received intravenous injection of glucocorticoids, 3 (4.0%) received intramuscular injection of 0.5 mg epinephrine, and 2 (2.7%) received antihistamines. All 75 patients showed improvement in symptoms, and no sequelae or deaths were found.Conclusions:In the emergency infusion room, the severity of anaphylaxis is mainly grade Ⅱ and Ⅲ with a good prognosis after timely intervention. The treatment measures mainly focus on rapid intravenous infusion for volume expansion, and the use of epinephrine is relatively low.

Long-segment lichen sclerosus (LS) urethral stricture is a challenge for urologists. Limited data are available for surgeons to make a surgical decision between Kulkarni and Asopa urethroplasty. In this retrospective study, we investigated the outcomes of these two procedures in patients with LS urethral stricture. Between January 2015 and December 2020, 77 patients with LS urethral stricture underwent Kulkarni and Asopa procedures for urethroplasty in the Department of Urology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine (Shanghai, China). Of the 77 patients, 42 (54.5%) underwent the Asopa procedure and 35 (45.5%) underwent the Kulkarni procedure. The overall complication rate was 34.2% in the Kulkarni group and 19.0% in the Asopa group, and no difference was observed ( P = 0.105). Among the complications, no statistical difference was observed in the incidence of urethral stricture recurrence ( P = 0.724) or glans dehiscence ( P = 0.246) except for postoperative meatus stenosis ( P = 0.020). However, the recurrence-free survival rate between the two procedures was significantly different ( P = 0.016). Cox survival analysis showed that antiplatelet/anticoagulant therapy use ( P = 0.020), diabetes ( P = 0.003), current/former smoking ( P = 0.019), coronary heart disease ( P < 0.001), and stricture length ( P = 0.028) may lead to a higher hazard ratio of complications. Even so, these two techniques can still provide acceptable results with their own advantages in the surgical treatment of LS urethral strictures. The surgical alternative should be considered comprehensively according to the patient characteristics and surgeon preferences. Moreover, our results showed that antiplatelet/anticoagulant therapy use, diabetes, coronary heart disease, current/former smoking, and stricture length may be contributing factors of complications. Therefore, patients with LS are advised to undergo early interventions for better therapeutic effects.

OBJECTIVE: In order to grasp the quality status of the first-aid ventilator in pre-hospital and field environment in time, the quality control and detection items of invasive ventilator were optimized to form a rapid detection operation process of first-aid ventilator and ensure the safety of patient treatment. METHODS: Based on the quality control detection data of invasive ventilator in hospital in recent years, methods such as narrowing the range of qualified criteria and analyzing confidence interval were adopted to extract indicators prone to deviation and verify their correlation with similar indicators, so as to form an optimized rapid detection portfolio. RESULTS: Compared with the original quality control detection procedures, the detection indicators of the rapid detection procedures were reduced from 5 categories of 24 indicators to 3 categories of 7 indicators. The detection time was shortened by 56.1% and the coincidence rate of the detection results was 100% after the actual measurement and verification. CONCLUSIONS Under the premise of ensuring the testing quality, the operating procedure for rapid detection of emergency ventilator can greatly reduce the detection time, and realize the rapid and high frequency quality control detection, so as to ensure the quality and safety of the equipment.

Objective: To establish an in vitro organoid model of human salivary gland basal cell adenoma (BCA). Methods: Fresh tumor sample from a 66-year-old female patient diagnosed with salivary gland BCA was collected from the Dpartment of Oral pathology, Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine in October 2021. And the organoid culture was performed in vitro in a culture medium based on solid droplets of matrix gel, and the growth of the organoid was observed by inverted microscopy. After 14 days, the organoid was fixed in 10% neutral formalin and made into paraffin blocks by agar pre-embedding paraffin embedding method, sectioned. HE staining, morphological observation and immunohistochemical staining of p63, Ki-67, cytokeratin14 (CK14), β-catenin, S-100 and calponin were used for organoids identification. Results: The established BCA organoids were lobulated nodular locally under light microscopy, with deposition of eosinophilic glass-like material around the nests of organoid cells, similar to the morphological architectures of the parental BCA. Immunohistochemistry showed that organoids expressed CK14, p63, and β-catenin in various degree, which was consistent with the immunophenotypic characteristics of the parental BCA tumor cells. Conclusions: An in vitro culture system of BCA organoids was preliminarily established which provides a new model for the study of the pathogenesis of salivary gland tumors.
