Objective To understand the influencing factors of chronic dyslipidemia in T2DM patients who signed a contract for diabetes point system management in Qingpu District, and to provide a basis for comprehensive intervention and prevention and control of dyslipidemia in T2DM patients and to optimize the management strategy of Qingpu District diabetes point system. Methods Among the T2DM patients who signed the diabetes point system from 2017 to 2023, patients with chronic dyslipidemia and normal blood lipids were selected and included in the case group and the control group, respectively. A case-control study was conducted with 1:1 matching by age and gender to analyze the factors influencing dyslipidemia. Results Multifactorial paired logistic regression analysis showed that overweight/obesity and central obesity and smoking in T2DM patients increased the risk of dyslipidemia by 1.93, 2.27, and 2.16 times, respectively. Long-term use of lipid-lowering drugs, duration of diabetes for 5 years or more, regular physical exercise, knowledge of blood lipid status, and married status could reduce the risk of dyslipidemia in T2DM patients (OR values were 0.547, 0.452, 0.685, 0.386 and 0.354, respectively). Current complications (history of stroke, coronary heart disease, and renal insufficiency) were also associated with dyslipidemia (OR=1.802, 95% CI:1.125-2.888). Conclusion The management of diabetes point system in Qingpu District should strengthen the feedback and interpretation of blood lipid monitoring results, improve patients’ health awareness of blood lipid management, and actively take comprehensive management of lifestyle intervention and drug treatment to effectively control blood lipid and reduce the occurrence of related complications.

Objective To understand the application effect of early screening scale and behavioral intervention effect in children with autism spectrum disorder (ASD). Methods A total of 348 children with suspected ASD were selected and evaluated using the Modified Checklist for Autism in Toddlers (M-CHAT) and Autism Behavior Checklist (ABC). The evaluation results were compared with those from the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Children enrolled were given Early start Denver model (ESDM) intervention. The evaluation results of Gesell Developmental Scale and Autism Treatment Evaluation Checklist (ATEC) scores were compared before and after intervention. Results The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating ASD in children aged 1-3 years were 89.53%, 90.70%, 89.92% and 0.78. The corresponding values of ABC were 78.49%, 81.40%, 79.46% and 0.56. The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating children aged >3-6 years were 87.30%, 77.78%, 84.44% and 0.64. The corresponding values of ABC were 85.71%, 77.78%, 83.33% and 0.62. The sensitivity and accuracy of M-CHAT were higher than ABC for evaluating ASD in children aged 1-3 years (P<0.05). There were no significant differences in sensitivity, specificity and accuracy between M-CHAT and ABC for evaluating ASD in children aged 3-6 years (P>0.05). After intervention, development quotients (DQ) of personal-social aspects, adaptability, language, gross motor, and fine motor of children with ASD were higher than those before intervention (P<0.05). ATEC scores for language, behavior, sensation, and social contact of children with ASD were lower than those before intervention (P<0.05). Conclusion M-CHAT and ABC both can be used for early screening of ASD in children, especially M-CHAT. Early behavioral intervention can effectively improve the condition and developmental level of children with ASD.

Objective: To explore the effect of different obesity indicators in predicting cardiovascular and cerebrovascular diseases (CVD) risk among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for the early identification of CVD risk among T2DM patients. Methods: The patients with T2DM under community management in Qingpu District, Shanghai Municipality were selected as the study subjects in January 2025. Basic information such as gender, age, and blood glucose control status were collected through the Shanghai Chronic Disease Information Management System, while history of CVD were obtained from residents' electronic health records and the Shanghai Disease Control Information Platform. Obesity was assessed using body mass index (BMI), waist circumference (WC), BMI combined with WC, waist-to-height ratio (WHtR), and triglyceride (TG) combined with WC indicators. The association between obesity and CVD was analyzed using multivariable logistic regression models. The predictive effect of each obesity indicators for CVD was evaluated using the area under the receiver operating characteristic curve (AUC). Results: A total of 4 367 patients with T2DM were included, including 2 121 males (48.57%) and 2 246 females (51.43%). The average age was (68.71±8.05) years. The prevalence of CVD was 44.49%. Multivariable logistic regression analysis showed that after adjusting for age, education level, history of hypertension, duration of T2DM, use of glucose-lowering medications, renal function, and blood glucose control status, obese T2DM patients had a 389.4% increased risk of CVD compared to those with normal BMI; centrally obese T2DM patients had a 100.4% increased risk compared to those with normal WC; T2DM patients with isolated general obesity and compound obesity had 161.0% and 241.1% increased risks of CVD, respectively, compared to those with normal BMI and WC; centrally obese T2DM patients had a 100.4% increased risk compared to those with normal WHtR; T2DM patients with normal TG-high WC and high TG-high WC phenotypes had 83.1% and 68.8% increased risks of CVD, respectively, compared to those with normal TG and normal WC (all P<0.05). BMI had the highest AUC, at 0.714, with sensitivity and specificity of 0.675 and 0.642, respectively. This was followed by BMI combined with WC, which had an AUC of 0.707, with sensitivity and specificity of 0.635 and 0.679, respectively. Conclusions Obesity defined by BMI, WC, BMI combined with WC, WHtR, and TG combined with WC increases the risk of CVD among patients with T2DM. BMI and BMI combined with WC have better predictive effect in predicting CVD risk among patients with T2DM, and can be used as the primary obesity indicators for CVD risk screening.

ObjectiveTo study the effect and mechanism of Yixintai on mitochondrial fission proteins in the rat model of chronic heart failure. MethodTen of 60 SD rats were randomly selected as the sham operation group， and the remaining 50 rats were subjected to ligation of the left anterior descending coronary artery for the modeling of heart failure post myocardial infarction. The successfully modeled rats were randomized into model， low-， medium-， and high-dose （1.4， 2.8， and 5.6 g·kg^-1， respectively） Yixintai， and trimetazidine （10 mg·kg^-1） groups. The rats were administrated with corresponding doses of drugs by gavage， and the rats in the model group and sham operation group were given an equal volume of normal saline by gavage for 28 consecutive days. Enzyme-linked immunosorbent assay （ELISA） was then employed to measure the levels of amino-terminal pro-B-type natriuretic peptide （NT-pro BNP）， B-type natriuretic peptide （BNP）， and adenosine triphosphate （ATP） in the serum. Color Doppler ultrasound imaging was conducted to examine the cardiac function indicators. Hematoxylin-eosin staining and Masson staining were conducted to observe the pathological changes in the heart， and Image J was used to calculate collagen volume fraction （CVF）. Transmission electron microscopy was employed to observe the ultrastructural changes of myocardial cells. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling （TUNEL） was employed to measure the apoptosis rate of myocardial cells. Western blot was employed to determine the protein levels of mitochondrial fission protein 1 （Fis1） and mitochondrial fission factor （Mff） in the outer mitochondrial membrane of the myocardial tissue. ResultCompared with the sham operation group， the model group showed elevated levels of NT-pro BNP and BNP in the serum， decreased ATP content， left ventricular ejection fraction （LVEF）， and left ventricular fraction shortening （LVFS）， increased left ventricular end-diastolic diameter （LVIDd） and left ventricular end-systolic diameter （LVIDs）， disarrangement of myocardial cells， inflammatory cell infiltration， increased collagen fibers and CVF， damaged myocardium and mitochondria， and increased apoptosis rate of myocardial cells， and up-regulated expression of Fis1 and Mff in the cardiac tissue （P<0.01）. Compared with the model group， different doses of Yixintai and trimetazidine lowered the serum levels of NT-pro BNP and BNP （P<0.05）， increased the ATP content （P<0.05）， increased LVEF and LVFS （P<0.01）， decreased LVIDd and LVIDs （P<0.01）. Moreover， the drugs alleviated the myocardial inflammatory damage and fibrosis， reduced CVF （P<0.01）， repaired the myocardial mitochondrial structure， and decreased the apoptosis rate of myocardial cells （P<0.01）. Medium- and high-dose Yixintai and trimetazidine down-regulated the expression of Fis1 and Mff in the myocardial tissue （P<0.05）. ConclusionYixintai can improve mitochondrial structure， reduce myocardial cell apoptosis， and improve cardiac function by inhibiting the expression of Fis1 and Mff in the myocardial tissue.

OBJECTIVE To investigate the effects of the peroxisome proliferator-activated receptors δ （PPARδ） agonist GW501516 on the injury of pulmonary artery endothelial cells （PAECs） induced by hypoxia and its mechanism. METHODS The cytotoxic effects of GW501516 were observed by detecting the relative survival rate of PAECs； the protein expression of PPARδ was determined by Western blot assay. The cellular model of PAECs injury was established under hypoxic conditions； using antioxidant N-acetylcysteine （NAC） as positive control， the effects of GW501516 on cell injury and reactive oxygen species （ROS） production were investigated by detecting cell apoptotic rate， cell viability， lactate dehydrogenase （LDH） activity and ROS levels. Using nuclear factor erythroid 2-related factor 2（Nrf2） activator dimethyl fumarate （DMF） as positive control， PAECs were incubated with GW501516 and/or Nrf2 inhibitor ML385 under hypoxic conditions； the mechanism of GW501516 on PAECs injury induced by hypoxia was investigated by detecting cell injury （cell apoptosis， cell viability， LDH activity）， the levels of superoxide dismutase （SOD）， glutathione peroxidase （GPx）， catalase （CAT）， malondialdehyde （MDA） and ROS， the expressions of Nrf2， heme oxygenase-1 （HO-1） and cleaved-caspase-3 （C-caspase-3） protein. RESULTS The results demonstrated that hypoxia inhibited the protein expression of PPARδ （P＜0.05）， while GW501516 promoted the protein expression of PPARδ in hypoxia- exposed PAECs without obvious cytotoxic effects. GW501516 inhibited the apoptosis of PAECs， improved cell viability， and reduced LDH activity and ROS levels. GW501516 could up-regulate the protein expression of HO-1 in PAECs and the levels of SOD， GPx and CAT， while down-regulated the levels of MDA and ROS by activating the Nrf2 pathway （P＜0.05）； but Nrf2 inhibitor ML385 could reverse the above effects of GW501516 （P＜0.05）. GW501516 exerted similar effects to Nrf2 activator DMF in down-regulating the expression of C-caspase-3 and inhibiting the injury of PAECs under conditions of hypoxia （P＜0.05）. Moreover， Nrf2 inhibitor ML385 reversed the 163.com inhibition effects of GW501516 on PAECs injury （P＜0.05）. CONCLUSIONS GW501516 can relieve the hypoxia-induced injury of PAECs via the inhibition of oxidative stress， the mechanism of which may be associated with activating Nrf2.

Objective To understand the characteristics and temporal trends of stroke incidence in the household population of Shanghai's Qingpu District and to provide a basis for the development of comprehensive prevention and control strategies. Methods The stroke case database for Qingpu District from 2017-2022 was obtained from the Shanghai Stroke and Acute Myocardial Infarction Registry and Reporting Information System. The average age of onset, incidence rate, standardised incidence rate, and constitutive ratio were calculated. Independent samples t-tests were used for comparisons between groups, 2-tests and 2-trend tests for comparisons of rates, and the Joinpoint regression model for calculating the annual percentage change (APC) to analyse the temporal trend of rates. Results Between 2017 and 2022, the average age of stroke onset in the household population of Shanghai's Qingpu District was 73.69±11.60 years. The average annual incidence rate was 556.62/100 000, with an average annual standardised incidence rate of 333.76/100000. There was an increasing trend in the incidence and standardised incidence of stroke in males (APC=7.06%, t=3.44, P=0.03, APC=5.32%, t=3.04, P=0.04). The incidence of stroke increases with age, with cases mainly concentrated in those aged 65 years and above, accounting for 79.47%. Ischemic stroke dominates the stroke typology, accounting for 91.08% of cases, while the incidence of hemorrhagic stroke shows an increasing trend (APC=4.64%, t=4.59, P=0.01). Conclusion The occurrence of stroke in the general population of Shanghai’s Qingpu District is concerning. The study indicates that males, individuals aged 65 years and above, and ischaemic stroke are significant factors that require attention for stroke prevention and control.

Objectives:To investigate the safety and efficacy of concomitant mitral valvuloplasty(MVP)and implantation of domestic third-generation magnetically levitated Corheart 6 left ventricular assist device(LVAD). Methods:Clinical data of 13 end-stage heart failure patients who underwent Corheart 6 LVAD implantation and MVP at Central China Fuwai Hospital of Zhengzhou University from October 2021 to March 2023 were retrospectively analyzed.Mortality and complication events during hospitalization and at follow-up were collected,and changes in myocardial injury biomarkers,renal function,hemodynamics,and echocardiographic indices were observed. Results:There were no perioperative deaths and no MVP-related complications in these patients.During a mean follow-up of(14.2±5.6)months,2 patients died due to COVID-19 pneumonia and cardiac arrest respectively,11 cases(84.6%)survived.There were no recurrences of moderate-to-severe mitral regurgitation in the survived patients.Compared with preoperative value,higher cardiac output,lower central venous pressure,pulmonary artery systolic pressure(PASP),and mean pulmonary artery pressure(PAMP)were evidenced at 24 h and 72 h postoperatively,estimated glomerular filtration rate was also reduced at 1 week post operation(all P<0.010).High-sensitive troponin T level was significantly increased at 1 week post operation and then reduced at 1 month post operation,but still not returned to pre-operative level([125.5±281.9]pg/ml at baseline,[1 295.6±654.6]pg/ml at 1 week post operation and[278.0±300.5]pg/ml at 1 month post operation).Echocardiography showed that compared with preoperative period,the left ventricular ejection fraction tended to be higher at 1 and 6 months postoperatively(both P>0.017),whereas left ventricular end-diastolic dimension,PASP,and PAMP were significantly reduced(all P<0.010). Conclusions:Domestic third-generation magnetically levitated Corheart 6 LVAD implantation with concomitant MVP is safe and feasible,there is no recurrence of moderate-to-severe mitral regurgitation,a significant reduction in pulmonary artery pressure,and significant hemodynamic improvement in early to mid-term postoperatively are observed in survived patients.
