Objective: To explore the interactive mechanisms of middle school students lifestyle with depressive and anxiety symptoms, so as to provide a basis for constructing a precise prevention system of middle school students mental health. Methods: From October to December in 2024, a stratified cluster random sampling method was used to select 6 251 middle school students from Guangxi. The Lifestyle Questionnaire, Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 ( GAD- 7) were used to investigate middle school students lifestyle, depressive symptoms and anxiety symptoms. The relationship of adolescent lifestyle with depressive and anxiety symptoms was analyzed through binary Logistic regression. The network analysis method was used to construct the network of middle school students lifestyle with depressive and anxiety symptoms. Results: A total of 1 690 individuals (27.0%) exhibited depressive symptoms, and 1 071 individuals (17.1%) exhibited anxiety symptoms. Binary Logistic regression analysis revealed that smoking, alcohol consumption, excessive intake of sugary drinks, insufficient vegetable intake, not eating breakfast daily, frequent consumption of fast food, prolonged sedentary time on both weekdays and weekends, insufficient sleep duration on weekdays and weekends, and excessive screen time on weekdays were all associated with depressive symptom ( OR =1.19-2.07) and anxiety symptom ( OR =1.20-1.91) in middle school students(all P ＜0.05). Additionally, excessive screen time on weekends was associated only with depressive symptoms ( OR =1.35, P <0.05). The connection between the lifestyle-depressive symptom cluster was mainly through "breakfast" and "suicidal ideation" (weight=0.31); the connection between the lifestyle-anxiety symptom cluster was mainly through "sedentary time on weekdays" and "uncontrollable worry" (weight=0.34). In the depressive symptom network, "depressed mood" had the highest node strength; in the anxiety symptom network, "uncontrollable worry" had the highest node strength. "Suicidal ideation" was a key bridge node between lifestyle and depressive and anxiety symptoms. Conclusions Unhealthy lifestyles are significant modifiable risk factors for depressive and anxiety symptoms among middle school students. Regular breakfast intake and management of sedentary behavior should be prioritized as important intervention entry points.

Under the background of deepening the medical and health system reform, it is necessary to explore the measures of fine and rational drug use management and strengthen the rational drug use. Through giving full play to the management functions of pharmacy administration and pharmacotherapeutics committee, formulating the performance evaluation index system of pharmacy affairs in the hospital, adhering to the prescription doctor′s advice review and prescription pre audit, continuing to carry out drug dynamic monitoring, implementing standardized-path antimicrobial drug management, the hospital implemented refined and rational drug use management. Before and after the management, the average drug cost, prescription unqualified rate, auxiliary drug amount and antibacterial drugs related indicators were significantly improved, suggesting that fine pharmacy management could promote the rational use of drugs in the whole hospital, promote the transformation of pharmacists′ work, and control the unreasonable growth of drug costs.

Objective: To explore the relationship between parents’ unstable marital status and offspring’s suicide attempts and the possible mediating factors, and to provide reference for suicide prevention among off spring grom unst able families. Methods: From 2017 to 2018, 2 766 valid questionnaires were collected from freshmen in a university in Hunan province. Students completed questionnaires of childhood trauma and depression traits,and reported their parents’ marital status and suicide attempts etc. Results: Compared to college students with parents of stable marital status,students with parents of unstable marital status showed higher reported rate of suicide attempts and higher scores of depression trait and childhood trauma (t/χ2=2.78, 5.83, 20.30, P<0.05). Controlling possible confounding factors,unconditional Logistic regression showed that childhood trauma,unstable marital status of parents and depressive traits were positively correlated with suicide attempt(OR=1.05, 1.45, 1.08, P<0.05). The 95% confidence interval of the Bootstrapping method with four mediation pathways (parental marital status→childhood trauma→depressive trait,childhood trauma→depressive trait→suicide attempt,parental marital status→childhood trauma→suicide attempt and parental marital status→childhood trauma→depressive trait→suicide attempt) does not include zero. Conclusion Childhood trauma and depressive traits mediate the relationship between parental instable marriage and suicide attempts in off spring.

Objective To explore the mediating effects of neuropeptide S receptor 1 and negative coping in chronic stress induced emotional responses. Methods A survey of 366 local residents who were chosen from County of Nandan in Guangxi Province by stratified random sampling method. Questionnaires of the life events scale (LES),the simplified symptom checklist and the Simplified Coping Style Questionnaire (SCSQ) were used. The level of NPSR1 was measured by Elisa. Data was analyzed by SPSS 21 and AMOS 21 statistical software for statistical analysis. Results The level of chronic psychological stress was (25. 24± 29. 26) and score of negative coping was(14. 84±4. 35). Somatic factor,anxiety factor,depressive factor and hostile factor were (1. 58±0. 58),(1. 43±0. 56),(1. 44±0. 55),(1. 23±0. 37). The total score of life e-vents was positively correlated with negative coping,somatic factor score,anxiety factor score,depression fac-tor score(r=0. 23-0. 46,P<0. 05),while negatively correlated with the expression level of detection of NPSR1 in plasma(r=-0. 26,P<0. 05). NPSR1 level was negatively correlated with body factor score,anxiety factor score,depression factor score and hostility factor score(r=-0. 18--0. 61,P<0. 05). Negative coping was positively correlated with body factor score,anxiety factor score,depression factor score and hostility fac-tor score(r=0. 12- 0. 27,P<0. 05). Both neuropeptide S receptor 1 and negative response had significant me- diating effects on emotional responses induced by chronic psychological stress (P<0. 05),and the effect val-ues were -0. 08 and 0. 05,respectively. According to the Bootstrapping method,the results of the mediation model showed that Bias-Corrected of 95% CI of the total standardization effect,the indirect standardization effect,the direct standardization effect were not including 0. Conclusion NPSR1 and negative coping plays a dual mediating effect on stress induced emotional responses.

Objective Acute aortic dissection occurs when a tear in the inside of the aorta causes blood to flow between the layers of the wall of the aorta,forcing the layers apart.In most cases this is associated with a sudden onset of severe chest or back pain,often described as "tearing" in character.The main management includes medication,endovascular repair and surgery.Medical management plays an very important role in the management of acute aortic dissection.Aortic dissection generally presents as a hypertensive emergency.Individuals can benefit from blood pressure control and anti-impulse therapy in perioperative period.

OBJECTIVE:To investigate the correlation of gene polymorphism in peripheral artery disease(PAD)patients with antiplatelet efficacy of clopidogrel. METHODS:Reviewing related domestic and foreign literatures in recent years,the correlation of gene polymorphism in PAD patients with antiplatelet efficacy of clopidogrel was summarized and analyzed. RESULTS&CON-CLUSIONS:At present,a variety of genes associated with clopidogrel antiplatelet efficacy and major adverse cardiovascular events (MACE)have been identified,including cytochrome P450(CYP)2C19,adenosine three phosphate binding cassette B subfamily 1 (ABCB1),paraoxonase 1 (PON1) and adenosine diphosphate P2Y12 receptor (P2Y12),etc. CYP2C19*2,*3 allele may reduce the antiplatelet effect of clopidogrel. Their correlation has been confirmed by a number of studies,and study results are broadly con-sistent. Mutations in the ABCB1 C3435T and PON1 Q192R sites may lead to a lower response to clopidogrel and increase the risk of MACE;but there is a lack of large-scale prospective clinical studies,and the present results are inconsistent. P2Y12 gene poly-morphism in PAD patients has not been found to be significantly associated with clopidogrel efficacy.

OBJECTIVE:To discuss the effect of performance management in medication consultation service in hospital,and to improve the service quality in medication consultation center. METHODS:The performance management mode of medication consultation center was implemented in our hospital through formulating consultation pharmacist performance evaluation content and accounting rules from four dimensions of business skills,cultural literacy,work attitude,workload,conducting daily evaluation and check,developing training,setting development plan,etc. The effects of the mode were evaluated. RESULTS:In performance evaluation,business skills,cultural literacy,work attitude and workload took up 20,15,15 and 50 points,respectively;they were subdivided into 16 specific items and extra point items. After the implementation of above performance management,average weekly clients increased from 104 persons to 247 persons (increasing by 138%);the proportion of patient medication education mainly provided by clinical pharmacists increased from 18.30% to 46.34%(increasing by 153%);the complex and professional problems of medication consultation such as drug interaction rose from 0.96% to 5.28%;the problem of drug usage and dosage in-creased from 6.73% to 23.17%. The performance management mode not only improved the service consciousness and the enthusi-asm of consultation pharmacists,but also improved the level of pharmaceutical care. CONCLUSIONS:Reasonable and effective performance management mode can promote the service quality and ability of medication consultation center,and play more impor-tant role in hospital pharmaceutical care.

OBJECTIVE:To provide theoretical foundation for individualized treatment of aspirin in patients with cardiovascu-lar disease. METHODS:Domestic and foreign literatures in recent years were collected and summarized. RESULTS & CONCLU-SIONS:The gene polymorphism can significantly affect the platelet activity. GPIII a PLA2,PEAR1 and PTGS1 alleles are associat-ed with aspirin resistance,and cardiovascular events have significant difference in different genotype patients. Adjusting reasonably dosage regimen and conducting individualized treatment according to the genetic testing result and other factors can reduce aspirin resistance and the incidence of cardiovascular adverse events in the patients.
