OBJECTIVE To construct ensemble learning models for predicting high-use days of budesonide based on meteorological factors， thereby providing reference for hospital pharmacy management. METHODS Meteorological data for 2024 and outpatient budesonide usage data from the jurisdiction of Sanming Hospital of Integrated Traditional Chinese and Western Medicine were collected. High-use days were defined as the 75th percentile of outpatient budesonide usage， and a corresponding dataset was established. The prediction task was formulated as a classification problem， and three ensemble learning models were developed： Random Forest， Extreme Gradient Boosting （XGBoost）， and Histogram-based Gradient Boosting Classifier. Model performance was evaluated using accuracy， precision， recall， F1-score， and log-loss. Model interpretability was analyzed using Shapley Additive Explanations （SHAP）. RESULTS The Histogram-based Gradient Boosting Classifier achieved the best performance （accuracy＝0.75， F1-score＝0.48）， followed by XGBoost （accuracy＝0.74， F1-score＝0.43） and Random Forest （accuracy＝0.72， F1-score＝0.22）. SHAP results suggested that the prediction results of the last two models have the highest correction. CONCLUSIONS Ensemble learning models can effectively predict high-use days of budesonide， with the Histogram- based Gradient Boosting Classifier demonstrating the best predictive performance. Low temperature， high humidity， and low atmospheric pressure show significant positive impacts on the prediction of daily budesonide usage.

Objective:To compare the perioperative outcomes between robotic pancreaticoduodenectomy(RPD)and laparoscopic pancreaticoduode-nectomy(LPD)in patients aged ≥65 years. Methods:The clinical data of 130 patients aged ≥65 years who received minimally invasive pancreaticoduodenectomy(MIPD)at Department of Gastrointestinal and Pancreatic Surgery,Zhejiang Provincial People's Hospital from January 2019 to December 2022 were retrospectively analyzed.The patients were divided into the RPD group(n=66)and the LPD group(n=64)according to the operation method,and the perioperative clinical data were compared between the 2 groups. Results:Compared with the LPD group,the average age of patients in the RPD group was higher than that of the LPD group[(71.95±4.73)years vs(70.39±3.9)years,P＜0.05];the RPD group had more patients with diabetes(39.4％vs 18.8％,P＜0.05)and cardiopulmonary diseases(37.9％vs 17.2％,P＜0.05);the RPD group had shorter operation time[(272.91± 68.38)min vs(362.81±78.24)min,P＜0.05]and less intraoperative blood loss[median(range):1 00 mL(50-200 mL)vs 1 50 mL(1 00-200 mL),P＜0.05)];the RPD group had higher incidence of chylous fistula(1 2.1％vs 1.6％,P＜0.05)but lower incidence of surgical morbidity(37.9％vs 46.9％),serious complications(19.7％vs 34.4％),postoperative pancreatic fistula(12.1％vs 17.2％),biliary fistula(3.0％vs 3.1％),abdominal infection(10.6％vs 14.1％),postoperative bleeding(4.5％vs 4.5％),and postoperative cardiopulmonary complications(1 2.1％vs 20.3％)with no statistically significant difference(P＞0.05);the RPD group waited shorter time before restarting diet[(3.97±1.59)d vs(5.34±2.56)d,P＜0.05]. Conclusion:MIPD is safe and feasible in patients aged ≥65 years.The incidence of perioperative complications is similar between the 2 groups.Compared with LPD,RPD has shorter operation time,less intraoperative blood loss,and shorter duration before restarting diet after operation,which has certain clinical advantages.

Objective:To investigate the effects of B ultrasound-guided lumbar plexus combined with sciatic nerve block on immune function, stress response, and postoperative analgesia in older adult patients undergoing hip surgery, providing theoretical evidence for clinical diagnosis and treatment.Methods:We included 300 older adult patients undergoing hip surgery who received treatment in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from August 2018 to August 2019 in this study. We randomly allocated them into the observation and control groups ( n = 150/group). The control group was subject to general anesthesia and the observation group was subject to B ultrasound-guided lumbar plexus combined with sciatic nerve block. Hemodynamic changes and plasma cortisol levels were recorded in each group immediately after endotracheal intubation (T1), at 2 hours of surgery (T2), at the end of surgery (T3), and 24 hours after surgery (T4). Each patient's immune function was assessed 3 months after surgery. The Visual Analog Scale score at each time point was compared between the two groups.

Objective To study the clinical features, diagnosis and treatment of torsion of testes in newborn. Method Neonates who were diagnosed with neonatal testicular torsion and admitted to Shenzhen Children's Hospital from March 2008 to July 2018 were studied. The clinical data such as days in age, time of onset, clinical manifestations, time of ultrasound examination, characteristics of ultrasound examination, surgery time, surgical types, postoperative conditions, pathological findings, and follow-up results were retrospectively analyzed. Result A total of 12 infants with torsion of testes were enrolled. The average onset time was 2.9 d, ranged from 1～10 d. The time of onset was within 24 h after birth in six infants. The median duration from onset to seeing a doctor was 3.5 d, ranged from 2 h to 28 d. First manifestations being reported grammer were scrotal swelling or mass, including 7 cases on the left side and 5 cases on the right side. Among them, 9 cases were associated with redness or cyanosis of the scrotum. Ultrasound was characterized by the disappearance or significant reduction of testicular parenchymal blood flow signal, and the sensitivity of ultrasound was 100％. The average time from admission to operation was (2.1±1.1) h. All the 12 infants had orchiectomy,after necrosis of unilateral testicle was confirmed. Eight of them underwent contralateral test icular fixation. The average operation time was 46 min. There was no wound bleeding or infection postoperatively, and the average hospital stay was 6.4 d. The pathological features were blurred residual contour of the seminiferous tubule (9 cases) or the disappearance of the seminiferous tubule structure (3 cases). After 3 to 24 months of follow-up, no contralateral testicular torsion or atrophy was found. Conclusion The rate of testicular necrosis in children with torsion of testes is high. The newborn with scrotal swelling should be diagnosed promptly with color Doppler ultrasound. If necessary, surgical exploration should be performed in time.

Objective To analyze the GDM of 336 cases with chronic HBV in pregnancy. Methods According to HBV DNA≥1.0 × 103 IU/mL, participants were divided into HBV DNA (+) or (-) group. 409 cases without HBV were selected as control group. Differences on GMD incidence between groups and virus load and OGTT blood sugar correlation were compared. Results The incidence of GDM of HBV DNA (+) or (-) group was 16.77% and 17.71%, which is higher than that in HBV group (10.27%). The difference is significant (P < 0.05). The correlation index between HBV DNA and fasting blood-glucose is r = 0.005, P = 0.610, the result of which is not statistically significant. But correlation index between HBV DNA and blood sugar at 1 h , 2 h are r = 0.082, 0.086; P = 0.000, 0.000, the result of which is statistically significant. Conclusion The oc-currence of GDM were higher in HBV DNA (+) or (-) group. The viral load is positively related with blood sugar of glucose tolerance at 1 h or 2 h.

Objective To investigate the risk of postpartum haemorrhage in HBV-infected pregnant women. Methods Cohort or case-control studies that discussed the relationship between hepatitis b virus infection and pregnancy outcome were searched in PubMed , EMBASE , Wiley Online Library , Cochrane Library , Google Scholar, CBM, WanFang database and CNKI etc. (till August 2015). The quality of included Cohort or case-control studies was evaluated , and Meta-analysis was performed with Rev Man5.2 software. Results Four observational case-control studies and 17 cohort studies , involving 19 549 women in observation , were identifled. Meta-Analysis results displayed that the incidence of postpartum haemorrhage in HBV-infected women was 9.3%, while 2.8% in women without HBV [RR = 2.97, 95% CI (2.25 ~ 3.92),P < 0.01]. Compared with normal-risk women , the incidence of postpartum haemorrhage of HBV-infected women with normal hepatic function was also higher [RR = 2.56, 95% CI (2.01 ~ 3.25),P < 0.01]. HBV-infected women with hepatic dysfunction had higher incidence of postpartum haemorrhage than those with normal hepatic function [RR = 2.67, 95% CI (2.17~ 3.28),P < 0.01]. Conclusions HBV-infected women are at higher risk of postpartum haemorrhage than normal pregnancy women and further hepatic dysfunction would lead to a continuing increase of the risk.

Objective To investigate the relationship between the cerebral microbleeds (CMBs) and changes of cognitive function,and the possible mechanism of cognitive impairment caused by CMBs.Methods Sixty-eight micro-hemorrhage patients on susceptibility weighted imagine (SWI) sequences composed positive group,and sixty-eight patients selected without micro-hemorrhage in the SWI sequence and meeting the selection criteria as control group.At the same time,both two groups were assessed by MoCA and CDT scale inspection.Results CDT scores of CMBs group (2.00±0.88) were significantly lower than those of control group (3.76±0.53),and there was significantly different in the two groups (t=-3.27,P=0.00).At the same time,MoCA total scores and executive functions,naming,calculation,language,abstraction,recall scores of CMBs group were significantly lower than those of control group,and all of the groups were significantly different (t=-5.48,P=0.00; t=-4.36,P=0.00; t=-2.35,P=0.01 ; t=-2.49,P=0.02; t=-4.09,P=0.00; t=-4.63,P=0.00).CDT scores,MoCA total scores,executive functions,language,abstraction,memory scores between CMBs groups and control group were significantly different at all levels (P＜0.05).Executive functions,languages and calculated inter-group of mild CMBs,moderate CMBs,severe CMBs were significantly different (P＜0.05).The number of CMBs was negative correlation with total scores,executive function,language,and abstract (r=-0.675,P=0.000; r=-0.689,P=0.000; r=-0.536,P=0.000; r=-0.636,P=0.000).Conclusion The existence of CMBs and the number of CMBs are closely related to cognitive dysfunction.The more of CMBs,the more of obvious cognitive impairment.
