ObjectiveTo investigate the recurrence of ischemic stroke (IS) and to analyze the association between four indices of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and the risk of IS recurrence by analyzing the follow-up data related to IS in the community-based natural population of Songjiang District, Shanghai, so as to provide a scientific basis for improving the prognosis of stroke patients in the community and controlling IS recurrence. MethodsA prospective follow-up study was conducted among the IS patients in the community-based cohort population, collecting data about patient’s age, gender, disease history, biochemical indicators, and etc. Cox regression model and restricted cubic spline model were used to analyze the relationship between different levels of plasma lipids and the recurrence of IS in these patients. ResultsA total of 1 368 patients with IS were included. The total follow-up duration was 7 171.46 person-years, with a median follow-up time of 6.24 years. There were 420 cases of IS recurrence, resulting in a cumulative recurrence rate of 30.70%. The results of multivariate Cox regression analysis showed that the recurrence risk of IS was reduced when the baseline TC and LDL-C levels of IS patients were in the ranges of 4.65‒5.67 mmol·L^-1 and 2.52‒3.46 mmol·L^-1, respectively. The results of restricted cubic spline analysis showed a U-shaped relationship between baseline TC and LDL-C levels and the recurrence risk in IS patients. ConclusionThe cumulative recurrence rate of patients with IS in the community of Songjiang District in Shanghai is high, and the levels of TC and LDL-C at baseline survey are correlated with the recurrence of IS in these patients. It is suggested to pay more attention to the levels of LDL-C and TC in patients with IS, so as to improve the prognosis.

ObjectiveTo develop a nomogram-based risk prediction model for chronic obstructive pulmonary disease (COPD) incidence among the community-dwelling population aged 40 years old and above, so as to provide targeted references for the screening and prevention of COPD. MethodsBased on a natural population cohort in suburban Shanghai, a total of 3 381 randomly selected participants aged ≥40 years underwent pulmonary function tests between July and October 2021. Cox stepwise regression analysis was used to develop overall and gender-specific risk prediction models, along with the construction of corresponding risk nomograms. Model predictive performance was evaluated using the C-indice, area under the curve (AUC) values, and Brier score. Stability was assessed through 10-fold cross-validation and sensitivity analysis. ResultsA total of 3 019 participants were included, with a median follow-up duration of 4.6 years. The COPD incidence density was 17.22 per 1 000 person-years, significantly higher in males (32.04/1 000 person-years) than that in females (7.38/1 000 person-years) (P<0.001). The overall risk prediction model included the variables such as gender, age, education level, BMI, smoking, passive smoking, and respiratory comorbidities. The male-specific model incorporated the variables such as age, BMI, respiratory comorbidities, and smoking, while the female-specific model included age, marital status, respiratory comorbidities, and pulmonary tuberculosis history. The C-indices for the overall, male-specific, and female-specific models were 0.829, 0.749, and 0.807, respectively. The 5-year AUC values were 0.785, 0.658, and 0.811, with Brier scores of 0.103, 0.176, and 0.059, respectively. Both 10-fold cross-validated C-indices and sensitivity analysis (excluding participants with a follow-up duration of <6 months) yielded C-indices were above 0.740. ConclusionThis study developed concise and practical overall and gender-specific COPD risk prediction models and corresponding nomograms. The models demonstrated robust performance in predicting COPD incidence, providing a valuable reference for identifying high-risk populations and formulating targeted screening and personalized management strategies.

Objective To analyze the nursing cost effectiveness of non-indwelling bladder catheter in thora-coscopic sublobectomy,and in order to further determine the feasibility of patients undergoing sublobectomy without indwelling catheter.Methods We prospectively collected the clinical data on a total of 254 patients undergoing thoracoscopic sublobectomy in the department of pulmonary surgery of Guangdong Provincial People's Hospital from May 2021 to January 2023.The patients were randomly divided into a study group(128 patients without catheter)and a control group(126 patients with catheter).The nursing cost-effectiveness indexes and postoperative comfort scores were compared between the two groups.Results Seven patients in the experimental group and sixteen patients in the control group needed repeated placement of urinary catheter There were no significant differences in the general demographic and clinical data between the two groups(P>0.05).The cost of materials related to urinary catheter,nursing cost,and total cost in the control group were higher than those in the study group.The total nursing time in the control group was longer than that in the study group.The per capita material cost,nursing cost and total cost in the control group were higher than those in the study group,and the differences were statistically significant(P<0.01).The total score of the comfort scale and the physiological and environmental dimension of postoperative comfort were significantly higher in the study group than in the control group,with statistical significances(P<0.05).Conclusions Thoracoscopic sublobectomy without indwelling bladder catheter can lower medical expense,reduce nursing workload,and improve postoperative comfort.

ObjectiveTo analyze the incidence， recovery rate and associated factors of nonalcoholic fatty liver disease （NAFLD） among residents aged 65 years old and above in Xinqiao Community of Songjiang， Shanghai， and to provide basic data for further efficient community management. MethodsData of annual geriatric physical examination program for residents aged 65 and above were collected in Xinqiao Community， Songjiang from 2016 to 2022. Those residents who participated twice or more were included in this analysis. Data were collated into longitudinal form. For each participant， data of the first physical examination was used as baseline， and each subsequent examination was taken as follow-up. Incidence and recovery rate of NAFLD were calculated. Cox proportional hazard models were used to explore the associated factors and their changes with the onset and recovery of NAFLD. ResultsDuring the study period， a total of 11 983 residents participated in physical examinations， of which 8 644 participated twice or more， and 8 154 had no history of excessive alcohol consumption. B-ultrasound showed that there were 5 267 residents without NAFLD and 2 887 with NAFLD at baseline. After a median follow-up of 3.3 years， the incidence density of NAFLD in this population was estimated to be 11.5 per 100 person-years， and the recovery density was 23.4 per 100 person-years. The incidence density of NAFLD was negatively associated with age， and positively associated with baseline BMI， abdominal obesity， high fasting blood glucose， and high triglycerides. The recovery density was negatively associated with baseline BMI and abdominal obesity. Compared with those with normal BMI at both baseline and follow-up， those with persistent obesity showed the highest risk of NAFLD （males： HR： 3.19， 95%CI： 2.16-4.70； females： HR： 3.34， 95%CI： 2.46-4.54） and the lowest potential of recovery （males： HR： 0.58， 95%CI： 0.42-0.82； females： HR： 0.58， 95%CI： 0.44-0.77）. Persistently high triglycerides were also associated with a higher risk of developing the disease. ConclusionResidents aged 65 years old and above in Xinqiao， Shanghai had a higher incidence and recovery rate of NAFLD. Women， being obese and having hyperlipidemia are at a higher risk for the development and persistence of NAFLD.

Objective This study aims to investigate the regulatory effects of Fujiu Patch(composed of Sinapis Semen,Kansui Radix,Corydalis Rhizoma and Asari Radix et Rhizoma)on the CD4+ T helper 17 cell(Th17)/CD4+CD25+ regulatory T cell(Treg)balance in asthmatic rats via the signal pathway of IL-6/signal transducer and activator of transcription 3(STAT3)as well as IL-2/signal transducer and activator of transcription 5(STAT5),and to reveal its anti-asthma mechanisms.Methods An experimental asthma model was constructed by ovalbumin(OVA)combined with aluminum hydroxide sensitization and challenge,and then the rats were administered with Fujiu Patch at Dazhui(DU14),Feishu(BL13)and Shenshu(BL23)points for 4 hours each time,once every other day for 7 times.Immunohistochemistry was used to detect the positive expressions of Th17 specific cytokine(IL-17)and Treg transcription factor(Foxp3)in rat lung tissue.The percentage of Th17 and Treg cells in peripheral blood was examined by flow cytometry analysis,and the expressions of IL-6/STAT3 and IL-2/STAT5 pathway-related proteins in lung tissue were assayed with Western Blot.Results Compared to the model group,IL-17 positive expression in the rat lung showed a significant reduction in the Fujiu Patch group(P＜0.01),while the positive expression of Foxp3 was obviously increased(P＜0.05).Meanwhile,the protein expression levels of IL-6 and phospho-STAT3 were were significantly declined(P＜0.01),and the protein expression levels of IL-2 and phospho-STAT5 were were significantly elevated(P＜0.01).However,there was no significant alteration in the total protein expressions of STAT3 and STAT5(P＞0.05).Furthermore,the proportion of Th17 cells in peripheral blood of rats in the Fujiu Patch group was lower than that in the model group,while the proportion of Treg cells was higher than that in the model group.Statistically-significant differences were observed(all P＜0.01).Conclusion These findings indicate that Th17/Treg immune imbalance occurs in asthmatic rat.Fujiu Patch may exert anti-asthma effects via inhibiting the expression of IL-6,downregulating the expression of phospho-STAT3,diminishing the level of IL-17-producing Th17 cells,as well as increasing the expressions of IL-2-mediated STAT5 phosphorylation,raising the level of Foxp3-expressing Treg cells,promoting Th17/Treg balance and suppressing immune responses in rat with asthma.

ObjectiveTo evaluate the efficacy of three screening questionnaires for COPD in the community residents of Songjiang District， Shanghai， and to provide a basis for selecting COPD screening questionnaire and process that are more suitable. MethodsCommunity residents aged 40 years or over were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for the study with screening questionnaires and spirometry. Questionnaires included the COPD screening questionnaire （COPD-SQ）， the COPD population screener （COPD-PS） and the revised COPD diagnostic questionnaire （revised-CDQ）. Evaluation of the efficacy of these questionnaires was based on the area under the receiver operating characteristic curve （AUC） of the subjects. DeLong test was used to compare the accuracy of different questionnaires； Z test was used to compare the accuracy of different cut-off values for the same questionnaire. ResultsAmong 3 184 community residents， a total of 259 （8.1%） COPD patients were screened by spirometry. AUC values of these 3 screening questionnaires were >0.7 indicating that they were reliable COPD screening tools. The sensitivity and specificity of the questionnaires at the recommended cut-off values were COPD-SQ （63.7% and 72.2%）， COPD-PS （12.0% and 96.1%）， and revised CDQ （78.8% and 52.7%）， with the COPD-SQ having the highest screening accuracy （AUC=0.754）. The optimal and recommended cut-off values for the three questionnaires differed in this population， but the difference in accuracy was statistically significant only for COPD-PS. The optimal cut-off values for the three questionnaires differed between male and female， and the sensitivity and accuracy of COPD-SQ and COPD-PS improved when lower cut-off values were used for women. The AUC was greater when two questionnaires were utilized simultaneously for screening， but the differences were not statistically significant. ConclusionThe COPD-SQ is recommended for primary COPD screening； a lower cut-off value for women should be considered. The COPD screening questionnaire needs to be further improved for the early diagnosis and treatment of COPD patients.

Objective To analyze the effect of neurofeedback training based on early start Denver model(ESDM)on children with autism spectrum disorder(ASD). Methods From August,2020 to May,2024,a total of 60 children with ASD from Hangzhou Children's Hospital were randomly divided into control group(n=30)and observation group(n=30).The control group received ESDM intervention,while the observation group received neurofeedback training in addition,for six months.They were assessed with Autism Treatment Evaluation Checklist(ATEC)and Psycho-Educational Profile-3rd Edition(PEP-3). Results After treatment,the score of ATEC was lower in the observation group than in the control group(t=3.545,P<0.05),the scores of cognition(t=2.236,P=0.029),emotional expression(t=2.293,P=0.025)and problem be-havior(Z=2.099,P=0.036)were higher in the observation group than in the control group.The score differenc-es of ATEC(Z=3.620,P<0.001),and cognition(Z=2.920,P<0.05)and problem behaviors(Z=4.209,P<0.05)of PEP-3 before and after intervention were higher in the observation group than in the control group. Conclusion Combination of neurofeedback training could improve the effect of ESDM on ASD.

ObjectiveTo investigate the prevalence of stroke in Songjiang District from 2017 to 2022, to analyze the epidemiological characteristics of stroke incidence, so as to provide a scientific basis for the formulation of stroke prevention and control policies. MethodsData of new stroke incidence from 2017 to 2022 in Songjiang District were obtained from the Shanghai Stroke and Acute Myocardial Infarction Registration and Reporting Information System. In addition, different classifications such as time of onset, gender, age group and types of stroke, were statistically analyzed. Statistical indicators, such as the number of incidence, crude incidence rate, standardized incidence rate and average age of incidence were calculated simultaneously. Joinpoint software were used to calculate the annual change percentage (APC) and the trend of stroke incidence in Songjiang District. ResultsFrom 2017 to 2022, the newly reported cases of stroke were 12 988 in Songjiang District, the crude incidence rate was 325.76/10⁵, and the standardized incidence rate was 127.58/10⁵. The crude incidence rate and standardized incidence rate in males were 363.45/10⁵ and 157.17/10⁵, respectively, but 288.68/10⁵ and 99.02/10⁵ in females. The mean age of onset was (73.12±11.75) years, of which the mean age of onset was (70.86±11.96) years for men and (75.91±10.85) years for women. The incidence of stroke increased with age, rising rapidly after 60 years and reaching a peak in the age group of ≥ 80 years old. The crude incidence rate and standardized incidence rate of stroke in Songjiang District showed a downward trend from 2017 to 2022, with an APC of -6.20% and -8.01%, respectively (P=0.018, 0.007). The newly reported stroke was dominated by ischemic stroke, accounting for 82.81% of the total cases, with a crude incidence rate of 269.77/10⁵ and a standardized rate of 103.84/10⁵. The incidence of stroke presented seasonal characteristics, with the highest incidence in winter, accounting for 26.11% of the whole year. ConclusionThe incidence rate of stroke in Songjiang District shows a declined trend, but the overall incidence is still at a high level. The situation of prevention and control is still serious, with a heavy disease burden. It is necessary to strengthen health education and disease management for the elderly.

Objective:To explore the incidence of chronic obstructive pulmonary disease (COPD) in a cohort aged 40 years and above in Songjiang District, Shanghai, and to analyze the association of Mediterranean diet pattern and dietary approaches in stopping hypertension pattern (DASH) with the risk of developing COPD.Methods:Based on a natural population cohort in Songjiang District, Shanghai, 27 474 adults aged 40 years and above who did not have COPD at baseline were enrolled in the study. The Cox proportional risk regression model was used to analyze the association of baseline Mediterranean diet pattern score and DASH score with the risk of COPD, and the hazard ratio ( HR) of the risk and its 95% CI were calculated. Restricted cubic spline was used to analyze the nonlinear association between the two diet scores and the risk of COPD. Stratified analyses were performed according to gender, age, smoking status, etcetera. Sensitivity analyses were conducted by censoring cases diagnosed within one year after the baseline survey or people with a history of malignant tumor disease. Results:As of June 30, 2023, after a median follow-up time of 6.21 years, there were 1 089 (4.0%) new COPD cases with an incidence density of 64.00 per 10 000 person-years. After adjusting for relevant confounders, in the Mediterranean tertile subgroups under diet pattern score, the risk of developing COPD could be reduced by approximately 14% in the intermediate scoring group ( HR=0.86, 95% CI: 0.75-0.99) and 15% in the highest scoring group ( HR=0.85, 95% CI: 0.72-0.99) compared to the lowest scoring group. The association remained after censoring cases diagnosed within one year of the baseline survey ( HR=0.82, 95% CI: 0.70-0.95; HR=0.82, 95% CI: 0.68-0.97) or censoring people with a history of malignant tumor disease ( HR=0.84, 95% CI: 0.73-0.97; HR=0.84, 95% CI: 0.71-0.99). No statistical association was found between the DASH score and the risk of COPD. Conclusions:The Mediterranean diet pattern was associated with a lower risk of COPD. Increasing the intake of vegetables, fruits, legumes, and whole grains and decreasing the intake of red meat and others can reduce the risk of COPD. No association was found between the DASH dietary pattern and the risk of COPD in this community population.

Objective To observe the changes of plasma gastrointestinal hormones in motion sickness sensitive and insensitive individuals before and after vertical oscillation stimulation,and to construct a susceptibility prediction model for motion sickness.Methods A total of 60 healthy male volunteers were enrolled to receive sinusoidal vertical oscillation stimulation for 45 min.The motion sickness susceptibility questionnaire(MSSQ)was filled out before the experiment.Immediately after motion,the severity of motion sickness was evaluated by Graybiel scale.The motion sickness sensitive(Graybiel score≥8 and MSSQ susceptibility index＞21,n=15)and insensitive(Graybiel score≤2 and MSSQ susceptibility index＜5,n=15)participants were screened.Plasma levels of glucagon-like peptide-1(GLP-1),cholecystokinin(CCK),leptin,ghrelin,neuropeptide Y(NPY)and orexin A(OXA)were detected by enzyme-linked immunosorbent assay before and after vertical oscillation stimulation.Logistic regression model was used to analyze the predictive effect of plasma gastrointestinal hormone levels on susceptibility to motion sickness,and a combined predictive model was established.Receiver operating characteristic(ROC)curve was used to analyze predictive value of the model.Results Ghrelin and CCK levels were significantly increased in the sensitive group after stimulation compared with those before stimulation(both P＜0.01),while NPY and leptin levels were significantly decreased(both P＜0.01).Similar results were also observed when compared with the insensitive group after stimulation.Multivariate logistic regression analysis showed that plasma ghrelin,CCK and NPY were independent predictors of susceptibility to motion sickness.The established susceptibility prediction model for motion sickness was logit(P)=-0.051 ×ghrelin+0.060× NPY-0.169 ×CCK+33.397.ROC curve analysis showed that area under curve(AUC)value of the prediction model was 0.988,the sensitivity and specificity were 100.0％and 93.3％,respectively,and the prediction effect was better than ghrelin,CCK and NPY alone(AUC=0.792,0.880,0.838).Conclusion The changes of peripheral gastrointestinal appetite regulating hormone levels may be related to the susceptibility to motion sickness.The combined use of these indicators can predict the susceptibility to motion sickness.
