0bjective To explore the effectiveness of caregivers based on health education under the guidance of timing theory in the nursing of elderly patients after hip replacement.Methods By convenient sampling method,eighty elderly patients undergoing hip replacement were divided into control group and observation group,40 cases in each group.The control group was given routine orthopedic care,and the observation group was based on health management under the guidance of the timing theory(total hip replacement,TIR)based on routine orthopedic care.The Harris Hip Score,Activities of Daily Living Scale(Barthel index),Caregiver Burden Inventory and Family Caregiver Task Inventory were used to compare and evaluate the application effect of health education of two groups of caregivers in the nursing of elderly patients after hip replacement.Results The patients were observed one month and three months after discharge,the Harris score and Barthel index of the observation group were significantly higher than those of the control group(P<0.01).At discharge,1 month after discharge and 3 months after discharge,the FCTI score(P<0.01)and CBI score(P<0.01)of family caregivers in the observation group were significantly lower than those in the control group.Conclusion Caregivers based on health education under the guidance of timing theory can effectively reduce the care burden of caregivers,enhance the care ability of caregivers,improve the rehabilitation effect of patients,and ameliorative the quality of life of patients.

Purpose: To intelligently diagnose whether there is bladder outlet obstruction (BOO) in female with decent detrusor contraction ability by focusing on urodynamic study (UDS) data. Materials and Methods: We retrospectively reviewed the UDS data of female patients during urination. Eleven easily accessible urinary flow indicators were calculated according to the UDS data of each patient during voiding period. Eight diagnosis models based on back propagation neural network with different input feature combination were constructed by analyzing the correlations between indicators and lower urinary tract dysfunction labels. Subsequently, the stability of diagnostic models was evaluated by five-fold cross-validation based on training data, while the performance was compared on test dataset. Results: UDS data from 134 female patients with a median age of 51 years (range, 27–78 years) were selected for our study.Among them, 66 patients suffered BOO and the remaining were normal. Applying the 5-fold cross-validation method, the model with the best performance achieved an area under the receiver operating characteristic curve (AUC) value of 0.949±0.060 using 9 UDS input features. The accuracy, sensitivity, and specificity for BOO diagnosis model in the testing process are 94.4%, 100%, and 89.3%, respectively. Conclusions The 9 significant indicators in UDS were employed to construct a diagnostic model of female BOO based on machine learning algorithm, which performs preferable classification accuracy and stability.

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.

To implement the fundamental task of the Ministry of Education on carrying out curriculum ideological and political education and promoting colleges and universities to implement the morality education, this study tried to carry out ideological and political education for medical students in "medical functional science experimental course", and organically integrated the ideological and political elements of "loving experimental animals and reverencing for life" into the teaching of this course. This paper explored the implementation process and effect evaluation of ideological and political courses from the aspects of teaching objects, design, objectives, in-class and off-class practical activities, and analyzed the current problems and future directions. In order to provide beneficial ideas for the ideological and political construction of college curriculum and help cultivate excellent and innovative medical talents with warmth and feelings.

Integrated experiment course is beneficial to optimizing the whole structure of medical courses and plays an important role in improving medical students' comprehensive quality and innovation capability. After several years of reform and exploration, Shanghai Jiao Tong University School of Medicine has developed the medical functional integrated experiment course with concept of "strengthen quality, reinforce foundation, encourage innovation and provide professional service", established a diversified evaluation system, and developed a corresponding assessment scale for reviewing students' comprehensive ability and the quality of experiment teaching. This paper investigated and prospected how to construct and optimize this evaluation system from the aspects of the relationship between evaluation method and course structure, and their effects, so as to provide strategic guidance for the further development of integrated experiment course.

Objective · To design and synthesize five new tropane compounds, and test their antagonistic activity against M3 receptor and inhibition activity to neutrophil elastase (NE), of which the structure-activity relationship were preliminarily investigated. Methods · The five compounds, A1-A3,B1 and C1, were prepared with 3α-hydroxy-tropane (A0) as the starting material by modifying the structure in C-3α position and N atom on the tropane skeleton. The antagonistic activity of the compounds to muscarinic M3 receptors on tracheal rings of guinea pigs was evaluated by functional assays in vitro. The hydrolysis of PGlu-Pro-Val-PNA as substrate was catalyzed by NE to get colorful nitroaniline (PNA). The NE inhibition activity of the tropane compounds was obtained by determining the absorbance [(D(405 nm)] of PNA. Results · The five new tropane compounds generated strong antagonistic activity against M3 receptors. Among them, A2 had the greatest activity [antagonistic parameter pA2(M3)=9.004], and elicited obvious inhibitory effect to NE (inhibition ratio YA2=20.29%). Conclusion · Introducing strong electron-attraction group, such as sulfuryl and hydrophobic group with large volume into C-3α position on the tropane skeleton can improve the M3 receptor antagonistic activity as well as the NE inhibition activity.
