Objective To compare the effects of remimazolam and propofol on postoperative nausea and vomiting(PONV)after pancreatic extracorporeal shock wave lithotripsy(P-ESWL),with the aim of optimizing the anesthesia regimen for this procedure.Methods Clinical data were retrospectively collected from patients who underwent P-ESWL for pancreatic stones under general anesthesia at The First Affiliated Hospital of Xi'an Jiaotong University from January 2021 to December 2024.A total of 307 patients were recruited,with 103 in the remimazolam group and 204 in the propofol group.Inverse probability of treatment weighting(IPTW)based on propensity scores was used to balance baseline characteristics and confounding factors between the two groups.The incidence of PONV and anesthesia recovery time were compared between the two groups.Results Before IPTW,there were statistically significant differences between the remimazolam and propofol groups in gender[male/female:51/52 vs.155/49],smoking history(27.2％vs.42.6％),intraoperative sufentanil use[25(10)μg vs.30(10)μg],remifentanil use[429.00(177)μg vs.480.50(209)μg],rocuronium use[36(6)mg vs.38(7)mg],and intraoperative dexamethasone use(62.1％vs.49.0％)(all P＜0.05).After IPTW,the baseline characteristics and confounding factors were balanced and comparable between the two groups(P＞0.05).Before IPTW,the incidence of PONV was higher in the remimazolam group than in the propofol group(24.3％vs.14.7％,P=0.039).After IPTW,the two groups did not significantly differ in the incidence of PONV(21.5％vs.17.5％,P=0.215),and the anesthesia recovery time was significantly shorter in the remimazolam group than in the propofol group[3(3)min vs.9(4)min,P＜0.001].Conclusion Compared to propofol anesthesia,remimazolam does not increase the incidence of PONV in patients undergoing P-ESWL for pancreatic stones and can effectively reduce anesthesia recovery time.

Objective:To analyze the self-efficacy of medical students in independent learning and its influencing factors, and to explore the ways to improve their self-learning ability.Methods:A questionnaire survey was conducted among medical students in 6 medical institutions of higher learning in Guangdong Province. A total of 2 480 questionnaires were issued, and 2 282 were recovered. SPSS 19.0 was used to conduct statistical analysis including Kruskal-Wall test and multiple comparisons.Results:There were 47.72% of the medical students who had a strong autonomous learning drive, and more than half of the medical students had strong autonomous learning ability with strong self-efficacy of independent learning. The influence of family location, family guidance degree and different grades on self-efficacy of medical students was different, and there was no significant difference between 5-year and 8-year clinical medical students in self-efficacy of independent learning.Conclusion:Family factors have a great influence on self-efficacy, and senior medical students have the strong ability of self-learning compared with junior medical students. Therefore, we should give full play to the positive impacts of family and school factors to further improve the independent learning ability and efficiency of medical students.

The adhesion in the gallbladder triangle is the most important factor influencing the conversion to laparotomy in laparoscopic cholecystectomy (LC).The degree of adhesion in the cholecystic triangle is closely related to the difficulty of LC operation.With the reduction of cholecystic triangle adhesion,the treatment of gallbladder during LC will be easy and the rate of conversion to laparotomy will decrease accordingly.In order to investigate the causes of cholecystic triangle adhesion and its influence on LC,this paper reviews the current research progress.

Early-onset epilepsy is a neurological abnormality in childhood, and it is especially common in the first 2 years after birth. Seizures in early life mostly result from structural or metabolic disorders in the brain, and the genetic causes of idiopathic seizures have been extensively investigated. In this study, we identified four missense mutations in the SETD1A gene (SET domain-containing 1A, histone lysine methyltransferase): three de novo mutations in three individuals and one inherited mutation in a four-generation family. Whole-exome sequencing indicated that all four of these mutations were responsible for the seizures. Mutations of SETD1A have been implicated in schizophrenia and developmental disorders, so we examined the role of the four mutations (R913C, Q269R, G1369R, and R1392H) in neural development. We found that their expression in mouse primary cortical neurons affected excitatory synapse development. Moreover, expression of the R913C mutation also affected the migration of cortical neurons in the mouse brain. We further identified two common genes (Neurl4 and Usp39) affected by mutations of SETD1A. These results suggested that the mutations of SETD1A play a fundamental role in abnormal synaptic function and the development of neurons, so they may be pathogenic factors for neurodevelopmental disorders.
