Objective To explore the relationship between education level and the risk of all-cause mortality in the middle-aged and elderly (≥45 years old) population in China. Methods Using data from five surveys from 2011-2020, years of education, age, gender, marital status, type of household, alcohol consumption status, smoking status, physical activity, limited ability to perform activities of daily living (ADLs), chronic disease status, and body mass index were collected. According to the survival status，the study participants were divided into a survival group (n=8625) and an all-cause mortality group (n=1735). Cox proportional risk regression model was used to analyze the relationship between years of education and the risk of all-cause mortality in middle-aged and elderly people with stratified analysis. Results The survey was conducted on 10360 research subjects, including 4 983 males and 5 377 females, with an age M(Q_R) of 59(8) years old. A total of 88 187 person years (average 8.512 person years) were followed up, and a total of 1735 deaths were reported over 9 years. The all-cause mortality rate was 19.674 ‰, with an education period M(Q_R) of 5(8) years and a survival time M(Q_R) of 9 (0) years. After adjusting for confounding factors, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.60% [HR=0.974, 95% CI (0.960-0.988)]. The stratified analysis results showed that in the population aged 45-59, for every 1 year increase in education, the risk of all-cause mortality decreased by 1.00% [HR=0.990, 95% CI (0.959,1.021)]; In the population aged 60-74 and over 75, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.70% [HR=0.973, 95% CI (0.948, 0.999)] and 3.50% [HR=0.965, 95% CI (0.929, 1.003)], respectively. Conclusion Improving the education level of middle-aged and elderly people (≥ 45 years old) in China can reduce the risk of all-cause mortality, and elderly education should be vigorously promoted.

Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

OBJECTIVE To investigate the reference range of steady-state trough concentrations in depression patients taking paroxetine. METHODS Therapeutic drug monitoring data of 890 depression inpatients treated with paroxetine in our hospital from January 1， 2023 to December 31， 2024 were retrospectively collected. Univariate analysis and multiple linear regression analysis were employed to explore the influencing factors of the steady-state trough concentration of paroxetine， as well as the correlation between concentration and efficacy and adverse reactions. The reference range of steady-state trough concentration was obtained by receiver operating characteristic（ROC） curve method. RESULTS Patients with a greater degree of improvement in therapeutic efficacy exhibited higher steady-state trough concentrations of paroxetine （P＜0.000 1）. The steady-state trough concentrations of paroxetine and the ratio of paroxetine steady-state trough concentration to dose （C/D ratio） were significantly lower in male patients and those weighing 60-80 kg compared to female patients and those weighing＜60 kg， respectively （P＜0.05 or P＜0.000 1）. The steady-state trough concentration， C/D ratio， dosage， and concomitant medication all showed a positive correlation with therapeutic efficacy （P＜0.05 or P＜0.000 1）. Both the steady-state trough concentration and C/D ratio were correlated with liver function impairment， and the C/D ratio was also correlated with urinary retention （P＜0.05 or P＜0.000 1）. The critical threshold for the effective concentration of paroxetine was 56.31 ng/mL in the overall population， 56.42 ng/mL in males， 44.91 ng/mL in females， and 198.90 ng/mL in patients experiencing adverse reactions. CONCLUSIONS The reference range for the steady-state trough concentration of paroxetine in the overall population is 56.31-198.90 ng/mL； for male patients， it is 56.42-198.90 ng/mL， and for female patients， it is 44.91-198.90 ng/mL. Dosage of paroxetine should be reduced as appropriate for female patients and patients with low body weight or abnormal liver function.

OBJECTIVE To resolve account discrepancies caused by drug price adjustment in medical institution pharmacy management and reduce the time required for price adjustment. METHODS The problems existing in the drug price adjustment models of domestic medical institutions were investigated， and a drug price adjustment system was developed based on price- invoice synchronization mechanism. The system optimized the drug price adjustment process through batch number matching and real-time monitoring functionalities. The account consistency rate and price adjustment time were evaluated before and after system implementation. RESULTS A drug price adjustment system was successfully developed， featuring an innovative “synchronized entry and exit” mode， batch number matching， real-time monitoring， intelligent automation， and electronic traceability. After implementation， the account consistency rate for Western medicines increased from 86.89% （86.66%， 89.63%） to 100% （100%， 100%） （P＝0.005）， while Chinese patent medicines and herbal medicines maintained a 100% （100%， 100%） account consistency rate. Concurrently， the drug price adjustment time significantly decreased from 6.00 （5.00， 7.00）d to 2.50 （1.50， 3.00） d （P＜ 0.001）. CONCLUSIONS The developed system significantly improves account consistency， shortens price adjustment time， and demonstrates notable innovation and practical utility.

Objective: To investigate the epidemiological characteristics of epidemic encephalitis B in Huzhou City, Zhejiang Province from 2007 to 2023, so as to provide the evidence for formulating prevention and control measures for epidemic encephalitis B. Methods: Epidemic encephalitis B case data in Huzhou City from 2007 to 2023 were collected through the National Notifiable Disease Reporting System of the Chinese Disease Prevention and Control Information System. The temporal, regional and population distribution characteristics of laboratory-confirmed epidemic encephalitis B cases were analyzed using the descriptively epidemiological method. Results: A total of 49 laboratory-confirmed epidemic encephalitis B cases were reported in Huzhou City from 2007 to 2023, and the average annual incidence was 0.10/105, showing a significant downward trend (P<0.05). The epidemic encephalitis B cases were concentrated from July to August, and July was the peak month, with 40 cases accounting for 81.63%. There was a statistically significant difference in the average annual incidences of epidemic encephalitis B among counties (districts) (P<0.05). Nanxun District had the highest reported incidence, with an average annual incidence of 0.23/105. There were 30 male cases and 19 female cases, with a male-to-female ratio of 1.58∶1. The youngest case was 5 months old, and the oldest was 49 years old. The children under 15 years were in the majority, with 42 cases accounting for 85.71%. Most of the cases were scattered children, with 25 cases accounting for 51.02%. There were 22 cases with no vaccination history and 21 cases with an unknown vaccination history, accounting for 44.90% and 42.86% respectively. All cases presented with fever. Other main clinical symptoms included listlessness, drowsiness, vomiting and headache, with 47, 40, 33 and 29 cases respectively, accounting for 95.92%, 81.63%, 67.35% and 59.18%, respectively. Conclusions The incidence of epidemic encephalitis B in Huzhou City remained at a relatively low level from 2007 to 2023, with Nanxun District being the high-risk area and July being the peak month for disease incidence. Fever and listlessness were the predominant clinical manifestations. Strengthening vaccination for children under 15 years should be prioritized.

ObjectiveExploring the formula rules of commonly used traditional Chinese medicines（TCMs） for epidemic treatment from the Qin and Han dynasties to the Qing dynasty through data mining， providing reference for the prevention and control of contemporary epidemics. MethodsThe articles on epidemic treatment in the electronic database of Chinese Medical Code V5.0 were systematically searched， and the contents such as source， dynasty， author， diagnosis， formula name， therapeutic method and efficacy， and composition of medicines from each article that met the inclusion criteria were extracted. Then， an Excel standardized database was established， and Python programs were used for data mining to summarize the frequency of commonly used medicines and perform hierarchical cluster analysis， Pearson correlation analysis， and association rule analysis. ResultsA total of 1 595 formulas were included， involving 558 TCMs. The efficacy of these medicines could be classified into two categories， namely， expeling pathogenic factors and reinforcing healthy Qi. According to the frequency deconstruction analysis， high-frequency medicines were mainly detoxification， Fu-organ dredging， aromatization and promoting blood circulation， followed by the medicines with the effect of treating the lungs， such as clearing the lungs and resolving phlegm， clearing heat and purging the lungs， relieving cough and asthma， and purging the lungs and relieving asthma. And the proportions of acrid-warm herbs and acrid-cold herbs varied in different periods. Hierarchical clustering and correlation analysis both suggested TCMs for expeling pathogenic factors and reinforcing healthy Qi often formed stable combinations with high association degrees. Association rule analysis showed that the core acrid-warm herb was mainly Ephedrae Herba， and the core acrid-cold herb was mainly Forsythiae Fructus， resulting in the core formulas of Maxing Shigantang and Yinqiaosan. ConclusionThroughout history， the prevention and control of epidemics have been based on the principle of "preserving healthy Qi and avoiding toxic Qi"， focusing on the treatment of the causes and characteristics of epidemics through detoxification， Fu-organ dredging， and aromatization， emphasizing the use of Rhei Radix et Rhizoma and other herbs to dredge Fu-organ， eliminate toxins and pathogens， and playing the role of actively intervene with symptomatic medication. And based on the external manifestations of the body's struggle between evil and righteousness， diagnose and treatment according to syndrome differentiation was performed.

Objective To investigate the relationship of triglyceride-glucose(TyG)index and atherogenic index of plasma(AIP)with positive remodeling of coronary arteries in elderly coro-nary heart disease(CHD)patients with concomitant type 2 diabetes mellitus(T2DM).Methods A total of 120 elderly CHD patients with concomitant T2DM admitted to our department from January 2022 to June 2023 were continuously recruited,and according to the remodeling index,they were divided into positive remodeling group(47 cases)and non-positive remodeling group(73 cases).The clinical data were compared between the two groups.Multivariate logistic analysis was used to identify the risk factors for positive remodeling of coronary artery.Spearman correla-tion analysis was employed to analyze the correlation of TyG and AIP with positive remodeling.ROC curve was plotted to analyze the predictive value of TyG and AIP for the remodeling.Results The positive remodeling group had larger ratio of smoking,higher TG and HbA1c levels,and in-creased TyG index and AIP,but lower HDL-C and blood calcium levels than the non-positive re-modeling group(P＜0.05,P＜0.01).Univariate logistic regression analysis showed that smoking,TG,HDL-C,HbA1c,blood calcium,TyG and AIP were risk factors for positive coronary artery remodeling in elderly patients with CHD and T2DM(P＜0.05,P＜0.01).Multivariate logistic re-gression analysis showed that TyG index(OR=7.253,95％CI:2.458-13.364,P=0.035)and AIP(OR=6.017,95％CI:2.205-12.025,P=0.030)were independent risk factors for positive coronary artery remodeling in elderly patients with CHD and T2DM(P＜0.05).The AUC value of TyG index and AIP in predicting positive coronary artery remodeling in elderly CHD patients with T2DM was 0.783 and 0.766,respectively,and the value of their combination in the prediction was 0.868,which was significantly better than the indicator alone(P＜0.05).Conclusion TyG in-dex and AIP are closely associated with positive coronary artery remodeling in elderly CHD pa-tients with T2DM,and can be used as effective indicators in the prediction of positive remodeling,which is of great significance for early clinical identification of high-risk patients and formulation of individual intervention strategies.

Aim To investigate the effect and potential mechanisms of tetramethylpyrazine(TMP)on athero-sclerotic plaques.Methods 43 ApoE-/-mice were used to establish the animal model of atherosclerosis(As)by high-fat diet for 8 weeks,3 of which were used for model outcome verification,and another 40 model mice were randomly divided into model group,TMP low dose(25 mg/kg)group,TMP medium dose(50 mg/kg)group,TMP high dose(100 mg/kg)group and atorvastatin(AT,2.6 mg/kg)group,with 8 mice in each group;another 8 C57BL/6J mice were set as control group.After gavaging administration for 8 weeks,the levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein(LDL),high density lipoprotein(HDL)in the serum were detected by biochemical methods,and the As index was calculated.The levels of oxidized low density lipoprotein(ox-LDL),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),monocyte chemoattractant protein-1(MCP-1),intercellular adhesion molecule-1(ICAM-1)in serum were detected by ELISA method.The pathological changes of aorta was evaluated by HE staining.The aortic plaque formation was evaluated by oil red O staining,and the plaque area percentage was calculated.The aortic fibrosis was evaluated by Masson staining,and the collagen area percentage was calculated.The expression of monocyte macro-phage antibody-2(MOMA-2)and α-smooth muscle actin(α-SMA)in the aorta was detected by immunohistochemistry(IHC)method,and the plaque vulnerability index was calculated.The mRNA and protein expression of peroxisome pro-liferator-activated receptor γ(PPARγ),nuclear factor-κB p65(NF-κB p65)in aorta were detected by RT-qPCR or West-ern blot method.Results Compared with control group,the levels of TC,TG,LDL,ox-LDL,TNF-α,IL-1β,MCP-1,ICAM-1 in serum and As index of the mice were significantly increased in model group,while the level of HDL was sig-nificantly decreased(P＜0.05).The aorta showed pathological changes such as uneven thickening of the intima,accu-mulation of foam cells and fat cells,formation of a large number of plaques,lumen stenosis and infiltration of inflammatory cells;the percentage of aortic plaque area,percentage of collagen area,MOMA-2 and α-SMA positive area,plaque vulner-ability index were all significantly increased(P＜0.05).The mRNA and protein expression of PPARγ in aorta were sig-nificantly decreased,and the mRNA and protein expression of NF-κB p65 were significantly increased(P＜0.05).Com-pared with model group,the levels of TC,TG,LDL,ox-LDL,TNF-α,IL-1β,MCP-1,ICAM-1 in serum and As index of the mice were significantly decreased in the TMP medium,high dose group and AT group,the level of HDL was signifi-cantly increased(P＜0.05).The pathological changes of aorta were significantly improved.The plaque area percentage,collagen area percentage,MOMA-2 positive area percentage and plaque vulnerability index were significantly decreased,and the α-SMA positive area percentage was significantly increased(P＜0.05).The mRNA and protein ex-pression of PPARγ in aorta were significantly increased,the mRNA and protein expression of NF-κB p65 were significantly decreased(P＜0.05).Moreover,TMP exhibited a certain dose-dependent effect on various detection indicators(except MCP-1)in As mice.The regulatory effect of TMP high dose group on various detection indicators(except LDL and As index)in As mice was comparable or superior to those of AT group.Conclusion TMP can reduce the area of As plaque and improve the stability of vulnerable plaque in As mice,its mechanism may be related to regulating PPARγ/NF-κB signaling pathway,improving lipid metabolism and inhibiting inflammatory response.

Objective To describe the clinical features of patients with primary sclerosing cholangitis(PSC)in China based on a nationwide multicenter patient cohort,and to investigate the risk factors for prognosis.Methods A retrospective cohort study was conducted among the patients with a confirmed diagnosis of PSC based on the electronic medical record system of seven grade A tertiary hospitals across the country,and related data were extracted.The Mann-Whitney U test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.The Kaplan-Meier method was used to estimate liver transplant-free survival,and the log-rank test was used for comparison of survival rate between PSC patients with different features.The Cox regression model was used to identify independent risk factors for the prognosis of PSC patients and the interactions between key factors.Results A total of 107 patients were enrolled,among whom 55.6%(55/99)had large-duct PSC and 29.0%(31/107)had comorbidity with inflammatory bowel disease(IBD).The positivity rate of anti-neutrophil cytoplasmic antibody(ANCA)was 32.9%(24/73),and 50.0%(40/80)of the patients had an increase in IgG/IgM.The median symptom-to-diagnosis interval was 1 year(<1-4.0),and 38.3%(41/107)of the patients had progressed to decompensated cirrhosis at the time of diagnosis.The median liver transplant-free survival time was 114 months(95%confidence interval[CI]:62-166),with a 5-year survival rate of 65.7%.The multivariate analysis showed that an increase in total bile acid(TBA)(hazard ratio[HR]=1.006,95%CI:1.002-1.010,P=0.001)and a prolonged symptom-to-diagnosis interval(HR=1.252,95%CI:1.059-1.480,P=0.009)were independent risk factors for prognosis.The interaction analysis showed that compared with the female patients with TBA<50 μmol/L,both male and female patients with TBA≥50 μmol/L had a significant increase in the risk of liver transplantation or death(male:HR=16.563,95%CI:2.103-130.449,P<0.001;female:HR=17.009,95%CI:2.113-136.934,P<0.001),and compared with the patients with an age of<45 years and a TBA level of<50 μmol/L,the patients with an age of≥45 years and a TBA level of≥50 μmol/L had a significant increase in the risk of liver transplantation or death(HR=10.729,95%CI:1.325-86.859,P=0.026).Compared with the female patients with an symptom-to-diagnosis interval of≤2 years,the male patients with a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.825,95%CI:1.725-13.644,P=0.003),and compared with the patients with an age of<45 years and a symptom-to-diagnosis interval of≤2 years,the patients with an age of<45 years and a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.983,95%CI:1.366-18.173,P=0.015).Conclusion Compared with the reports from Western countries,large-duct PSC is also the main type of PSC in China,but with a relatively low proportion,and there is also a relatively low proportion of patients with IBD or positive ANCA.An increase in TBA and a prolonged symptom-to-diagnosis interval are independent risk factors for prognosis,with significant interactions with age and sex.This suggests that early screening and intervention should be enhanced to improve prognosis.
