ObjectiveTo construct a nomogram prediction model for non-valvular persistent atrial fibrillation （PeAF） patients with left ventricular hypertrophy （LVH） ， followed by prognostic analysis through follow-up. MethodsThis study retrospectively enrolled 949 patients with newly diagnosed and hospitalized non-valvular PeAF. Among them， 403 patients presented with LVH. The cohort was randomly stratified into a training set （n=665） and a validation set （n=284）. Univariate and multivariate Logistic regression analyses were employed to identify independent risk factors for PeAF complicated by LVH. A nomogram prediction model was subsequently constructed and evaluated for discriminative ability， calibration， and clinical utility using receiver operating characteristic （ROC） curve analysis， calibration plots， and decision curve analysis （DCA）. ResultsSeven independent risk factors were ultimately identified and included in the prediction model： female sex， hypertension， diabetes， red blood cell distribution width-SD （RDW-SD）， body mass index （BMI）， left atrial diameter （LAD）， and left ventricular ejection fraction （LVEF）. The area under the ROC curve （AUC） in the training set was 0.862 （95% CI： 0.834-0.890）， and in the validation set， it was 0.870 （95% CI： 0.829-0.911）， demonstrating excellent predictive performance. ConclusionIndependent risk factors for LVH in PeAF patients include female， hypertension， diabetes， RDW-SD， BMI， LAD， and LVEF. The prediction model built based on this can help early identification of PeAF patients with high risk of LVH. At the same time， the incidence of major adverse cardiovascular events （MACE） is higher in PeAF patients with LVH. Patients with atrial fibrillation combined with LVH may benefit from catheter ablation.

Da Chaihutang， first recorded in Shanghanlun by Zhang Zhongjing of the Eastern Han dynasty， is composed of eight medicinal herbs， namely Bupleuri Radix， Scutellariae Radix， Rhei Radix et Rhizoma， Aurantii Fructus Immaturus， Paeoniae Radix Alba， Pinelliae Rhizoma， Zingiberis Rhizoma Recens， and Jujubae Fructus. It features a well-defined hierarchy of sovereign， minister， assistant， and courier ingredients. The prescription is characterized by its balanced compatibility， mutually restrained cold and warm properties， and combined use of harmonizing and purging therapeutic strategies. As a renowned classical formula indicated for harmonizing Shaoyang and purging internal heat accumulation， it is the core prescription for the treatment of Shaoyang-Yangming combined disease. A comprehensive review of modern research literature on Da Chaihutang reveals that its chemical composition is notably diverse. The core pharmacologically active material bases of its constituent single herbs have been clearly identified， including saikosaponins from Bupleuri Radix， flavonoids from Scutellariae Radix， anthraquinones from Rhei Radix et Rhizoma， flavonoids and alkaloids from Aurantii Fructus Immaturus， monoterpene glycosides from Paeoniae Radix Alba， alkaloids and organic acids from Pinelliae Rhizoma， gingerols from Zingiberis Rhizoma Recens， and polysaccharides and triterpenoid acids from Jujubae Fructus. In the compound formula， a total of 163 chemical constituents have been comprehensively identified， among which flavonoids and their glycosides constitute the most abundant component category. Flavonoids and their glycosides， monoterpene glycosides， and pentacyclic triterpenoid saponins are regarded as the core pharmacologically active substances of the whole formula. In addition， 9 potential quality markers that can comprehensively characterize the overall quality and core therapeutic efficacy of the whole formula have been screened out. Modern pharmacological studies have shown that the pharmacological effects of Da Chaihutang exhibit synergistic characteristics involving multiple components， multiple targets， and multiple pathways. Its core pharmacological activities encompass the regulation of digestive system disorders， including pancreatic protection， intervention in biliary tract diseases， and protection of gastrointestinal mucosa； intervention in hepatobiliary diseases such as non-alcoholic fatty liver disease and cholestatic liver injury； and regulation of metabolic disorders such as hypoglycemic effect， improvement of insulin resistance， and regulation of lipid metabolism. Furthermore， it also possesses multiple pharmacological activities， including intervention in atherosclerosis， regulation of immune and inflammatory responses， multi-organ protection， and anti-hepatocellular carcinoma effect. In modern clinical practice， Da Chaihutang and its modified formulas are mostly used in combination with conventional Western medical regimens. They have demonstrated notable therapeutic advantages in the treatment of digestive system diseases such as cholecystitis， acute pancreatitis， cholelithiasis， and non-alcoholic fatty liver disease， but also have shown definite curative efficacy in the management of diseases affecting multiple other systems， including cardiovascular， endocrine， dermatological， reproductive， respiratory， neurological， urinary， pediatric， and immune systems. These combined applications can effectively improve the overall clinical response rate， shorten the time to symptom relief， and reduce both the disease recurrence rate and the incidence of adverse reactions. This review systematically summarized the formula compatibility， chemical constituents， pharmacological mechanisms， and modern clinical applications of Da Chaihutang and its modified formulas， to provide a theoretical basis and practical reference for the secondary development of classic formulas， the research and development of new drugs， and the precise and safe clinical application of this classical prescription.

Objective To explore the association of working hours and shift work with occupational stress, fatigue accumulation, and depressive symptoms among primary community medical workers. Methods A total of 516 medical workers from five community medical service centers in Pudong New Area, Shanghai City, were selected as the research subjects using the convenience sampling method. The Core Scale of Occupational Stress Measurement, the Workers' Fatigue Accumulation Self-diagnosis Questionnaire, and the Patient Health Questionnaire were used to assess research subjects' occupational stress, fatigue accumulation, and depressive symptoms, respectively. Results Long working hours (>40 hours/week) were reported by 50.4% of workers among the research subjects, while shift works were reported by 16.9% of the workers. The detection rates of occupational stress, fatigue accumulation, and depressive symptoms were 26.6%, 41.7%, and 30.8%, respectively. Multivariate logistic regression analysis result revealed that, after adjusting for confounders such as age, sex, and education level, longer working hours were associated with higher risks of occupational stress, fatigue accumulation, and depressive symptoms (all P<0.05). Shift workers in community medical centers had higher risks of occupational stress, fatigue accumulation, and depressive symptoms compared with non-shift workers (all P<0.05). Conclusion Long working hours and shift work could increase the risks of occupational stress, fatigue accumulation, and depressive symptoms among community medical workers.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

Objective To explore the application effects of a discharge planning service program based on King's Goal Attainment Theory in patients undergoing transcatheter heart valve surgery.Methods Using convenience sampling method,80 patients who underwent transcatheter heart valve surgery at a tertiary comprehensive hospital in Zhejiang Province from August 2023 to January 2024 were selected as the research subjects.Among them,40 patients from November 2023 to January 2024 were selected as an experimental group.A discharge preparation service plan for patients undergoing transcatheter heart valve surgery based on King's Goal Attainment Theory was adopted.Totally 40 patients who underwent transcatheter heart valve surgery from August to October 2023 were selected as a control group and underwent routine measures for discharge preparation.The differences in the scores of the discharge preparation scale,discharge guidance quality scale,self-management scale for patients after mechanical heart valve replacement surgery,and unplanned readmission rate were compared between 2 groups before and after intervention.Results During the application of the plan,a total of 2 cases were excluded,and 38 cases were included in the experimental group and 40 cases were included in the control group.After intervention,the experimental group had higher scores in discharge readiness,discharge guidance quality,and self-management ability than the control group,and the differences were statistically significant(P＜0.001).The unplanned readmission rate within 30 days in the experimental group(2.63％)was lower than that in the control group(7.50％),and the difference was not statistically significant(P＞0.05).Conclusion The discharge preparation service plan for patients undergoing transcatheter heart valve surgery based on King's Goal Attainment Theory can improve the discharge preparation,discharge guidance quality,and self-management ability of patients undergoing transcatheter heart valve surgery,and has a positive effect on improving their quality of life.

Objective To explore the trajectory of psychological symptom clusters in pregnant women with assisted reproductive technology(ART),and analyze the influencing factors of each trajectory subgroups,in order to provide a theoretical basis for the management of psychological health during pregnancy in pregnant women with ART.Methods A total of 205 pregnant women who had conceived using ART were sampled from the obstetrics clinic of a tertiary hospital in Nanjing from August 2023 to April 2024 using a convenient sampling method.The baseline data were assessed by general information questionnaire,Symptom Checklist-90,Distress Disclosure Index and Positive Psychological Capital Questionnaire at 10-14 weeks gestation,and the follow-up information was assessed by Symptom Checklist-90 at 22-26 weeks of gestation and 34-38 weeks of gestation.Exploratory factor analysis was used to extract symptom clusters;the latent class growth mixture model was used to identify the track categories;the multiple logistic regression analysis was used to analyze the influencing factors of the track.Results 180 cases were finally included.By exploratory factor analysis,5,4 and 5 factors were extracted at 3 time points respectively.Trajectories of psychological symptom clusters in pregnant women with ART is divided into 3 potential classes:low level-slow relieving group(28.89％),high level-significant increasing group(6.11％),medium level-slow increasing group(65.00％).Logistic regression analyses showed that duration of infertility,number of ART,literacy,pain self-expression and positive psychological capital were influential factors in the potential categories of psychological symptom clusters in pregnant women conceived with ART(all P＜0.05).Conclusion The trajectory of psychological symptom clusters in pregnant women with ART was divided into 3 potential classes.Medical workers could develop corresponding interventions based on the influencing factors and implement comprehensive and efficient symptom management.

Under the Healthy China strategy, the training of preventive medicine professionals should conform to the development of the times and the needs of public health. The article analyzed the problem of "disconnection between medical care and prevention" in teaching the course of Obstetrics and Gynecology for students majoring in preventive medicine, and proposed to strengthen the strategy of "integration of medical care and prevention". Guided by the concepts of "Comprehensive Health", with the cornerstone of cultivating morality and talents, the reform focused on enhancing the post competency of preventive medicine talents. Course content was optimized by reinforcing prevention-focused elements, student-centered teaching method innovation was advocated, and simulation-based training teaching system was established. Moreover, projects integrating science and education were used to improve faculty teaching capacity with tiered and diversified approaches. Course assessment methods were revised and "ideological and political education" was incorporated to establish the education concept of "emphasis on prevention and integration of medical care and prevention". The survey showed that these reform measures effectively improved the comprehensive clinical literacy of preventive medicine students in obstetrics and gynecology, which is of great significance for building a "integration of medical care and prevention" public health talent training model. In the future, the long-term effectiveness of course reform will be ensured from the perspectives of teaching resources, personnel investment, and policy support.
