Objective In light of the high noise and inter-class imbalance encountered in the prognosis prediction of coronary heart disease,this study aims to construct an EasyEnsemble imbalanced ensemble model after LASSO feature selection and evaluate its performance.Methods Based on survey data from the National Health and Nutrition Examination Survey public database for the years 2009-2018,with follow-up data until 2019,this study aimed to predict the prognosis of coronary heart disease based on whether there was death due to the disease as the outcome.LASSO feature selection was employed to select relevant features.Subsequently,an EasyEnsemble imbalanced ensemble prediction model,as well as SMOTE+LightGBM,XGBoost,and Random Forest prediction models,were constructed using the selected features.Grid search was performed to optimize the parameters of each model.The classification performance of the models was evaluated using metrics such as AUC,precision,specificity,G-mean,and performance curves.Additionally,SHAP analysis was applied to interpret the models'results and provide insights into their interpretability.Results The EasyEnsemble model exhibited the highest overall performance,with an AUC of 0.80(95％CI:0.79～0.82),precision of 0.86(95％CI:0.78～0.93),specificity of 0.99(95％CI:0.98～0.99),and G-mean of 0.79(95％CI:0.76～0.83),as evidenced by the performance curves.Additionally,age,serum phosphorus,diabetes,and albumin were identified as important factors influencing patient prognosis.Conclusion The LASSO- EasyEnsemble imbalanced ensemble model enables accurate prognosis prediction for coronary heart disease patients,combining SHAP can help clinicians better assess disease severity and identify at-risk groups for personalized patient management.

Objective:To investigate the outcomes of natural cycle (NC) and modified natural cycle (MNC) assisted reproductive technology (ART) in patients with diminished ovarian reserve (DOR), and to provide a scientific basis for individualized treatment strategies for DOR patients.Methods:A retrospective cohort analysis was performed on the clinical data of DOR patients who underwent ART at the Center for Reproductive Medicine of the Department of Obstetrics and Gynecology, Peking University Third Hospital from January 1, 2015 to December 31, 2023. Patients were divided into the NC group ( n=801) and the MNC group ( n=385) based on their treatment protocol. The primary outcomes were cycle cancellation rate and oocyte retrieval rate. Secondary outcomes included clinical pregnancy rate and live birth rate per fresh embryo transfer cycle and frozen-thawed embryo transfer cycle, cumulative pregnancy rate and cumulative live birth rate per started cycle and per transfer cycle, as well as laboratory parameters such as the number of retrieved oocytes, the number of two pronuclei (2PN) fertilized oocytes, the number of transferable embryos, and transferable embryo formation rate. Further, multivariate logistic regression was used to analyze the impact of the treatment protocol on pregnancy and live birth outcomes. Results:There were no statistically significant differences between the NC and MNC groups in terms of general characteristics such as age, body mass index, and baseline hormone levels (all P>0.05). The cycle cancellation rate was significantly higher in the NC group [19.10% (153/801)] than in the MNC group [10.65% (41/385), P<0.001], and the oocyte retrieval rate was significantly lower in the NC group [66.31% (431/650)] than in the MNC group [74.86% (259/346), P=0.005]. The number of retrieved oocytes [1 (0,1)], the number of 2PN fertilized oocytes [1 (0,1)], and the number of transferable embryos [0 (0, 1)] were also significantly lower in the NC group than in the MNC group [1 (1, 2), P<0.001; 1 (1, 1), P<0.001; 0 (0, 1), P<0.001]. However, there were no statistically significant differences in 2PN fertilization rate and transferable embryo formation rate between the NC and MNC groups (all P>0.05). In both fresh embryo transfer cycles and frozen-thawed embryo transfer cycles, there were no statistically significant differences in clinical pregnancy rate and live birth rate between the NC and MNC groups (all P>0.05). The cumulative pregnancy rate per started cycle and transfer cycle, the cumulative live birth rate per started cycle and per transfer cycle were also not significantly different between the NC and MNC groups (all P>0.05). Multivariate logistic analysis showed no significant association between NC and clinical pregnancy or live birth compared with MNC. Conclusion:While MNC to some extent reduced the cycle cancellation rate and improved oocyte retrieval rates compared with NC, it did not ultimately improve pregnancy outcomes in DOR patients.

Objective To develop the Ego Depletion Scale for Type 2 Diabetes Patients and evaluate its reliability and validity,and to provide a specific assessment tool for evaluating ego-depletion in self-management.Methods Guided by the self-control strength model,the initial scale was constructed through literature review,semi-structured interviews,2 rounds of expert consultation,and a pilot survey.A convenience sampling method was employed to recruit 460 patients with Type 2 Diabetes from the endocrinology department of a tertiary hospital in Wuhan,Hubei Province,between April and July 2024.They were randomly divided into 2 subsets for exploratory factor analysis and confirmatory factor analysis.Results A total of 451 valid questionnaires were collected.Exploratory factor analysis extracted 6 common factors,with a cumulative variance contribution of 73.231％.In confirmatory factor analysis,an item was deleted due to failing to meet the standardized loading value criterion.The revised Ego Depletion Scale for Type 2 Diabetes Patients comprised 6 dimensions and 22 items.The total Cronbach's α coefficient was 0.911;split-half reliability was 0.744;the content validity index was 0.860.Correlation coefficients between the total score and scores of each dimension of the scale and the total score of the Self-Regulatory Fatigue Scale ranged from 0.558 to 0.946(P＜0.001).Conclusion The scale exhibits robust reliability and validity,serving as a scientifically instrument for assessing ego depletion in patients with Type 2 Diabetes.

Objective:To analyze the changes in the prevalence characteristics of multimorbidity among adolescents aged 13-18 in Inner Mongolia Autonomous Region from 2019 to 2022 and to explore the association between multimorbidity and moderate to high-intensity physical activity among them.Methods:A stratified random cluster sampling method was used to select students aged 13-18 in Inner Mongolia Autonomous Region every September from 2019 to 2022. Physical examinations, demographic characteristics, and depression-related surveys were conducted to analyze the multimorbidity of overweight, obesity, high blood pressure, myopia, spinal curvature abnormality, and depression. A logistic regression model was used to analyze the association between multimorbidity and moderate to high-intensity physical activity.Results:From 2019 to 2022, 70 972, 62 923, 80 254, and 78 288 study subjects were included, with the rates of multimorbidity being 56.4%, 55.4%, 57.2%, and 55.8%, respectively. The rates of multimorbidity remained relatively stable from 2019 to 2022 ( χ2=0.06, P=0.950). The incidence of multimorbidity among girls was significantly higher than that among boys ( P<0.001). The incidence of multimorbidity among urban students was significantly higher than that among suburban students ( P<0.001). The incidence of multimorbidity among high school students was higher than that among middle school students ( P<0.001). The top three multimorbidity combinations were myopia and overweight/obesity (26.4%), myopia and high blood pressure (24.4%), and myopia and depression (19.8%), while the least common combination was depression and spinal curvature abnormality (1.1%). The multimorbidity patterns showed no significant differences between years ( χ2=0.03, P=0.999). The multimorbidity status was significantly associated with the status of meeting the standard of moderate to high-intensity physical activity ( OR=0.83, 95% CI: 0.80-0.86). The association was stronger in boys ( OR=0.77, 95% CI: 0.73-0.81) compared with girls ( OR=0.90, 95% CI: 0.85-0.96), with a significant interaction term ( P<0.001). Conclusion:From 2019 to 2022, the incidence of multimorbidity among adolescents aged 13 to 18 in Inner Mongolia Autonomous Region is relatively high, mainly due to the co-occurrence of myopia and other health problems. Adequate physical activity is an important factor in reducing multimorbidity.

Ligusticum sinense cv.Fuxiong derived from"Xiongqiong",and in the Song Dynasty's Tai Ping Hui Min He Ji Ju Fang,it was already distinguished from Chuanxiong Rhizoma in usage.Doctors in the Ming Dynasty further clarified the differences in efficacy between the two.However,with the widespread circulation of Chuanxiong Rhizoma,Ligusticum sinense cv.Fuxiong gradually became marginalized,serving as a substitute,and is now only cultivated and used in small quantities within Jiangxi Province.This article reviewed the prescriptions and the ancient Chinese medical books that have records of Ligusticum sinense cv.Fuxiong,analyzed its specific applications alongside Chuanxiong Rhizoma in prescriptions and case studies to elucidate their differences in efficacy:Ligusticum sinense cv.Fuxiong is pungent and has strong dispersing power and is good at unblocking meridians and promoting qi circulation,which is suitable for excessive syndromes;Chuanxiong Rhizoma is good at promoting blood circulation and relieving pain,and is good at regulating and nourishing,which is suitable for patients with deficiency syndromes,aiming to provide insights and recommendations for the further development and rational clinical medication of Ligusticum sinense cv.Fuxiong.

Background:Rhei Radix et Rhizoma has been traditionally used as a potent laxative for centuries due to its remarkable efficacy.Raw pieces of Rhei Radix et Rhizoma(RP)are known for their strong laxative effects,often accompanied by side effects,while steamed Rhei Radix et Rhizoma pieces(SP)possess a milder laxative effect and are widely used clinically.However,there is a lack of comprehensive evidence examining the mechanisms underlying SP's effectiveness,particularly from a bioavailability perspective.Objective:This study aimed to investigate the impact of the steaming process on the in vivo disposition of RP and SP through pharmacokinetics,tissue distribution,and excretion assays.Methods:An ultra-performance liquid chromatography-tandem mass spectrometry method was developed for the simultaneous quantitative analysis of prototype anthraquinones and their glucuronide metabolites.Pharmacokinetic,tissue distribution,and excre-tion assays were conducted in constipation rats following oral administration of RP and SP.Blood,tissue,urine,and fecal samples were collected and analyzed to compare the absorption,distribution,metabolism,and excretion profiles of anthraquinones,high-lighting differences in bioavailability and safety between RP and SP.Results:Compared with the RP group,the SP group showed significantly reduced area under the plasma concentration-time curve,mean residence time,and half-life time values for rhein-8-O-β-D-glucopyranoside,rhein,emodin,aloe-emodin,and their glucuronide metabolites.The clearance values were significantly increased in the SP group.These results demonstrate that SP led to lower exposure levels and higher elimination rates of these components compared with RP.Additionally,these compo-nents were primarily distributed in the large intestine,where they exerted their laxative effects.Glucuronide metabolites were mainly excreted through urination,while prototype components were excreted in both urine and feces.Notably,the cumulative excretion of aloe-emodin,emodin,rhein,and their glucuronide metabolites was significantly higher in both urine and feces after SP administra-tion,indicating that SP enhances the excretion of these components compared with RP.Conclusion:The findings suggest that SP reduced anthraquinone exposure levels while enhancing their excretion,demonstrating that the steaming process significantly promotes the elimination of key components.This study provides a comprehensive analysis of how steaming alters the in vivo disposition of Rhei Radix et Rhizoma,offering a scientific basis for the improved safety and clinical use of SP.These insights not only clarify the mechanistic differences between RP and SP but also contribute to a broader understanding of processing-induced modifications in Chinese medicines.This research paves the way for optimizing Chinese medicine processing techniques to enhance the safety and efficacy of herbal therapies.
