AIM: To study the effects of nabumetone on immunological fuctions in mice METHODS: After nabumetone was given ig to mice, the weight of thymus and spleen, phagocytizing function of macrophages, PHA- induced lymphocyte transformation were observed respectively in mice RESULTS: The weight of thymus and spleen was decreased, the phagocytizing function of macrophages was reduced, PHA- induced lymphocyte transformation was markedly inhibited with nabumetone in mice CONCLUSION: The immunological function in mice was significantly inhibited with nonsteriod anti- inflammatory drug- nabumetone

Objective To compare the clinical effectivness of the treatment by open surgery and by therapeutic endoscopy for common bile duct(CBD) stones.Methods The randomised controlled trails on the open surgery or therapeutic endoscopy for CBD stones were identified by electronic-searching and hand-searching,meta-analysis was conducted using the methods recommended by the Cochrane Collaboration.Data of 407 patients included in 6 high-quality randomized controlled trials were meta-analyzed using in fixed effect model.Results Compared with endoscopic stone extraction technique,open surgery had retained stones after primary intervention rate(OR 0.39,95% CI 0.25 to 0.75,P=0.003) and additional procedures rate(OR 0.33,95% CI 0.19 to 0.60,P=0.0002) with statistical significance.But open surgery made no significant difference in postoperative complication rate(Peto OR 1.10,95% CI 0.69 to 1.76,P=0.67).Conclusion Current evidence suggests that there is no significant difference between open surgery and therapeutic endoscopy in preoperative complications,but open surgery is superior to therapeutic endoscopy in stone clearence rate.

Objective:To construct a predictive model for the risk of major adverse cardiovascular events(MACE) after surgery in patients with symptomatic arteriosclerosis obliterans(ASO) .Methods:From Jan 2018 to Dec 2021, 957 patients with symptomatic ASO admitted to Nanjing Drum Tower Hospital were selected and divided into MACE and non-MACE groups according to whether they had a post-op MACE. A risk prediction model was constructed based on a stepwise regression method with multi-factor COX regression analysis. The model was evaluated using the receiver operating characteristic curve (ROC), the calibration curve to assess the model fit, and the Bootstrap method for internal validation.Results:MACE occurred in 143 patients (14.94%). After COX regression analysis, BMI, creatinine clearance, fibrinogen, rivaroxaban and previous history of surgery were enrolled into model constructing. The ROC curve assessed the model with a C-statistic of 0.690 (95% CI: 0.644-0.736), sensitivity and specificity of 49.2% and 80.7% respectively, a Jorden index of 0.299 and an optimal cut-off value of 0.086. Calibration curves showing agreement between predicted and actual observed values. Internally validated C-statistic of 0.689 (95% CI: 0.672-0.700). The population was divided into high and low risk groups based on the best cut-off value and analysed for survival. The difference between the two groups was statistically different. Conclusion:The risk prediction model for the occurrence of MACE based on clinical parameters is simple and convenient, with good predictability and good discriminatory ability, and can provide reference for the assessment and treatment of MACE in ASO patients.
