Objective: To understand the association of physical exercise willingness and insomnia with depressive symptoms among college students, so as to provide reference for improving depressive symptoms of college students. Methods: From October 2022 to April 2023, cluster sampling was used to recruit 11 101 college students from four colleges in Anhui Province. The questionnaire survey was conducted to investigate the willingness to engage in physical exercise, insomnia and depressive symptoms of college students. The multivariate Logistic regression model was used to analyze the association of physical exercise willingness and insomnia with depressive symptoms of college students. Results: The prevalence of depressive symptoms among college students was 9.24%. Multivariate Logistic regression analysis showed that college students who were passive participants/non participants in physical activity, or who experienced insomnia, had a higher likelihood of depressive symptoms compared to those who were active participants or did not experience insomnia ( OR =1.84, 2.07, 4.02, all P <0.01). College students who were passive participants or non participants in physical activity and concurrently experienced insomnia had a higher risk of depressive symptoms compared with those who were active participants or did not experience insomnia ( OR =1.87-8.39, all P <0.01). Gender stratified analysis showed that the combined effect of passive physical exercise and insomnia increased the risk of depressive symptoms in both male ( OR = 1.81 -9.87) and female college students ( OR =1.67-7.39) (all P <0.05). Conclusions Both physical exercise willingness and insomnia are associated with depressive symptoms in college students. In order to improve the depressive symptoms of college students, it is necessary to improve the enthusiasm of physical exercise and strengthen the education of sleep health awareness.

Objective To systematically evaluate the efficacy and safety of the ceftazidime-avibactam(CAZ-AVI)regimen versus other regimens for treatment of carbapenem-resistant Enterobacteriaceae(CRE)bloodstream infections,and to provide an evidence-based foundation for drug selection in clinical CRE bloodstream infections.Methods A computerized search was conducted in Pubmed,Embase,Cochrane Library,Web of Science,Wanfang Medical Network,CNKI and China Science and Technology Journal Database for literature on CAZ-AVI for CRE bloodstream infections from the inception of each database up to November 2023.The literature quality evaluation and data extraction were independently performed by two researchers.A meta-analysis was performed using Review Manager 5.3 software.Results A total of 15 English articles and 1 580 patients were included.The results showed that the clinical cure rate[OR=3.32,95% CI=(2.25,4.90),P<0.000 01]and microbial clearance rate[OR=3.00,95% CI=(1.15,7.81),P=0.02]were significantly higher in the CAZ-AVI group than in the control group,and the 28 d/30 d all-cause mortality rate of patients in the CAZ-AVI group was lower than that of the control group[OR=0.38,95% CI=(0.29,0.51),P<0.000 01].The recurrence rates of infection in the two groups were equivalent and statistically non-significant[OR=0.75,95% CI=(0.39,1.42),P=0.37].Subgroup analysis indicated that the CAZ-AVI group had a lower all-cause mortality rate than the tigecycline group[OR=0.20,95% CI=(0.11,0.39),P<0.000 01].In terms of safety,the incidence of adverse events between the two groups was comparable and statistically non-significant[RR=0.47,95% CI=(0.20,1.07),P=0.07].However,the nephrotoxicity was significantly lower in the CAZ-AVI group than in the control group[OR=0.36,95% CI=(0.21,0.64),P=0.000 5].Conclusion Based on the findings of the current study,CAZ-AVI offers potential clinical advantages in the treatment of CRE bloodstream infections by improving clinical cure rates and reducing mortality rates.

Objective: To evaluate the effectiveness and safety of the endoscope combined with microscope for the microvascular decompression in hemifacial spasm. Methods: A total of 26 patients underwent endoscope combined with microscopic facial nerve microvascular decompression through retrolabyrinthine approach from January 2013 to December 2016 were retrospectively reviewed in Ear Institute, Shanghai Jiaotong University School of Medicine. Among them, 9 were male and 17 were female, with a mean age of (51.9±11.4) years;15 cases of left side and 11 of right side patients were followed up for 1-3 years. The pre-and post-operative Cohen Classification was used for hemifacial spasm, House-Brackmann Grade for facial nerve function, hearing level and complication rates were reviewed. SPSS 19.0 software was used to analyze the data. Results: All 26 patients were operated successfully. No recurrence was seen during 1-3 year follow-up. Post-operative Cohen Grade were as follows: 25 cases with Cohen Grade I and 1 case with Cohen Grade II. The difference in Cohen grade between pre-and post-operative was statistically significant (Z=-4.87, P<0.01). Post-operative facial nerve function was satisfactory in all patients (House-Brackmann Grade I-II in all patients). No hearing loss was observed. No facial paralysis and other lower cranial nerve dysfunction were observed. No postoperative complications such as cerebrospinal fluid leakage occurred. Conclusions Using an angled endoscope combined with microscope in microvascular decompression in hemifacial spasmis is safe and effective.

Objective To explore the effect of micro-lecture-CPT teaching method (case,problem and team-based learning,CPT) used in pathology teaching.Methods 236 medical imaging undergraduates from Grade 2015 were selected and divided into two groups equally.The experimental group (118 people) used the micro-lecture-CPT teaching method,and the control group (118 people) used the traditional teaching method.The students in the experimental group used the interactive platform on the internet to share the resource in combination with pathological theory and experiment,including curriculum,microlecture,multimedia courseware,clinical case and the related questions before class.In class,the questions were discussed in groups based on "student centered,teacher guide".Questionnaire survey and test scores were used to collect data and analyze the differences between the two groups.SPSS 13.0 was applied to processing the data.Measurement data were expressed as mean plus or minus standard deviation,and t test was used in the comparison between groups.Results The average score of basic theoretical examination in the experimental group was lower than that of the traditional teaching group [(57.86-± 2.32) vs.(58.23 ±2.06)];While the case score and experimental score in the experimental group were significantly higher than those of the traditional teaching group [(11.27 ± 1.24) vs.(7.40 ± 0.90);(18.04 ± 0.87) vs.(14.75 ± 0.93)].And the differences were statistically significant (P＜0.05).Questionnaire survey demonstrated that the experimental group students' evaluation on the learning of micro-lecture-CPT teaching was higher than the control group's evaluation on traditional teaching in the aspects of improving students' learning interest,promoting autonomous learning and problem solving skills,cultivating clinical thinking ability and team cooperation spirit.Conclusion Micro-lecture-CPT teaching method conforms to the trend of modem teaching reform and achieves good effect in pathology teaching,so it is worth recommending and popularizing.

Objective:To analyze the characteristics of health financing at the provincial level according to the total health expenditure since China health system reform began in 2009 and provide evidence for improving health fi-nancing policy. Methods:20 provinces were chosen and vertical and horizontal Comparative approach was used to an-alyze the data. Results:Total health expenditure increased for all regions, of which the biggest rate was Anhui prov-ince, about 82. 97%, while the largest increasing for government health care expenditure was Ningxia province, a-bout 108 . 71%. In 2012 , the provinces with social health expenditure share of total above 40% were allocated in the east region, and the number of provinces with out-of pocket payment share of total above 40% reduces to 5. Conclu-sion:Total health expenditure grew in all regions, but there were differences in the degree that this spending matched the economic level;The financing structure was optimized, but the characteristic of regional financing was different. Some provinces were under huge pressure to reduce out-of pocket payments. Suggestions: Under the premise of im-proving the funding level, financing structure adjustment must be focused, and public funding should play a bigger role and out-of pocket payments should be reduced.
