Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ²=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

Objective To investigate the exposure-response relationships and lag effects between air pollutants (PM_2.5, PM₁₀, O₃, and NO₂) and mortality in Jiading District, Shanghai, and to provide a scientific basis for the formulation of environmental health policies. Methods Using an individual-level time-stratified case-crossover design, conditional logistic regression models in conjunction with a distributed lag nonlinear model (DLNM) were employed to analyze the exposure-response relationship and temporal lag patterns of ambient air pollution on resident mortality in Jiading District (1994–2024). Results A total of 59 048 death cases were collected, including 18,701 deaths from cardiovascular diseases and 11 731 deaths from respiratory diseases. PM_2.5 and NO₂ had a significant impact on all-cause mortality, cardiovascular disease mortality, and respiratory disease mortality, with the most significant effects observed within a lag of 0–3 days. PM₁₀ also had some impact on these three types of mortality, but its effect was generally weaker than that of PM_2.5 and NO₂. The exposure-response curves showed that the risk of death increased rapidly with increasing concentrations of PM_2.5 and PM₁₀, while the effect of NO₂ plateaued at higher levels. No significant differences were found across age or gender subgroups. Conclusion Short-term exposure to PM_2.5, PM₁₀, and NO₂ significantly increases all-cause mortality risk in Jiading District, with effects persisting up to 7 days, highlighting the need for enhanced air pollution control measures, particularly targeting fine particulate matter.

Objective:To investigate the expression of erythropoietin-producing hepatocyte kinase receptor A10 (EphA10) in gastric cancer and adjacent tissues, and analyze its correlation with clinical features and prognosis.Methods:The clinical data of 112 patients with gastric cancer from January 2018 to December 2023 in Eastern Theater Command Air Force Hospital were retrospectively analyzed. The expression of EphA10 in gastric cancer and adjacent tissues was detected by EnVision immunohistochemical staining. The relationship between EphA10 expression and clinicopathological features was analyzed. The Kaplan-Meier survival curve was drawn, and the comparison used the log-rank test. Multivariate Cox regression was used to analyze the independent risk factors of the overall survival time in patients with gastric cancer.Results:The positive expression rate of EphA10 in gastric cancer tissues was significantly higher than that in adjacent tissues: 44.6% (50/112) vs. 0, and there was statistical difference ( χ2 = 64.37, P<0.01). In patients with gastric cancer, the positive expression of EphA10 in gastric cancer tissues was correlated with tumor long diameter, differentiation, TNM stage and lymph node metastasis ( P<0.01 or <0.05), but without age, gender and distant metastasis ( P>0.05). Kaplan-Meier survival curve analysis result showed that the median overall survival time in patients with positive EphA10 expression was significantly lower than that in patients with negative EphA10 expression: 18 months vs. 48 months, and there was statistical difference (log-rank χ2 = 53.66, P<0.01). Multivariate Cox regression analysis result showed that tumor long diameter ≥3 cm, TNM stage Ⅲ to Ⅳ, lymph node metastasis and EphA10 positive expression were the independent risk factors of the overall survival time in patients with gastric cancer ( HR = 1.250, 1.515, 1.321 and 0.831; 95% CI 1.143 to 1.368, 1.267 to 1.813, 1.168 to 1.497 and 0.756 to 0.913; P<0.01 or <0.05). Conclusions:The expression level of EphA10 in gastric cancer tissues is up-regulated, and its expression level is correlated with the clinicopathological features. EphA10 can be used as one of the reference indicators for clinical prognosis evaluation in patients with gastric cancer.

AIM: To quantify early changes of macular capillary parameters in type 2 diabetic patients using optical coherence tomography angiography(OCTA).METHODS: Retrospective case study. A total of 49 healthy subjects, 52 diabetic patients without retinopathy(noDR)patients, and 43 mild nonproliferative diabetic retinopathy(mNPDR)patients were recruited. Capillary perfusion density, vessel length density(VLD), and average vessel diameter(AVD)were calculated from macular OCTA images(3 mm×3 mm)of the superficial capillary plexus after segmenting large vessels and the deep capillary plexus. Parameters were compared among control subjects, noDR, and mNPDR patients. The area under the receiver operating characteristic curve estimated the abilities of these parameters to detect early changes of retinal microvascular networks.RESULTS: Significant differences were found in the VLD and AVD among the three groups(P<0.001). Compared with the control group, the noDR group had significantly higher AVD(P<0.05). VLD of both layers in patients of mNPDR group was significant decreased compared with that of noDR group(all P<0.01). Deep AVD had a higher area under the curve(AUC)of 0.796 than other parameters to discriminate the noDR group from the healthy group. Deep AVD had the highest AUC of 0.920, followed by that of the deep VLD(AUC=0.899)to discriminate the mNPDR group from the healthy group.CONCLUSIONS: NoDR patients had wider AVD than healthy individuals and longer VLD than mNPDR patients in both layers. When compared with healthy individuals, deep AVD had a stronger ability than other parameters to detect early retinal capillary impairments in noDR patients.

Objective:To analyze changes in nutritional status and immune function of elderly men receiving regular physical examinations, and to investigate the effects of aging on the nutritional status and immune function among elderly men.Methods:A total of 209 elderly men aged 60-101(72.9±11.5)years and receiving regular physical check-ups were enrolled.All research subjects were subjected to nutritional risk screening(NRS2002)and monitoring of nutrition and immune-related indicators, including routine blood work, blood biochemistry, immunoglobulin and T lymphocyte subsets.Results:Body weight, body mass index, hemoglobin, total protein, albumin and serum iron of elderly men decreased with age( F=21.754, 6.257, 47.528, 12.285, 18.397, 18.667, all P<0.001), with those aged 80 and above showing more significant decline and a greater proportion with malnutrition( χ2=77.134, P<0.001). The B lymphocyte counts of elderly men aged 80 and above were significantly lower( P<0.05)while serum IgA and IgG levels were significantly higher( F=3.110, 3.866, P=0.047, 0.022)than those of the 70-79 year old group.In addition, the B lymphocyte count and B lymphocyte ratio in malnourished elderly men were significantly lower( t=2.512, 2.874, P=0.013, 0.005), and IgA was significantly increased( t=2.513, P=0.017), compared with those with normal nutrition. Conclusions:The risk of malnutrition and reduced immune function among elderly men aged 80 years and above is significantly increased, and assessment and screening of the risk of malnutrition in the elderly should be stressed.

Objective:The aim of the present study was to observe the effects of liralutide on body composition and muscle function in adult obese patients with type 2 diabetes.Method:A total of 63 adult obese type 2 diabetic patients who were (52.6±9.7) years of age and with body mass index (BMI) of ≥28 kg/m 2 were enrolled. The patients were randomly assigned into two groups. On the basis of maintaining the original hypoglycemic regimen, patients in the control group ( n=24) were given dietary guidance only, and those in the treatment group ( n=39) were injected with liraglutide. All patients were followed up for a period of 12 weeks. Blood glucose, glycosylated hemoglobin(HbA1c) and insulin levels, liver and kidney function, body composition assessed with electrical impedance methods, and grip strength measured by a grip meter for muscle function were detected at the baseline and the end of the study. Results:Compared with those in the control group, the reductions in HbA1c [(-1.54±2.10) % vs.(-0.53±0.84) %], body weight [(-3.46±4.2) kg vs.(-0.34±3.66) kg], body fat mass [(-1.97±2.98) kg vs.(-0.01±2.16) kg] and visceral fat area [(-0.01±2.16) cm 2 vs.(0.34±6.39) cm 2] were more pronouced in liraglutide treated group (all P<0.05). However, no changes could be observed in muscle mass and grip strength after liraglutide treatment. Conclusions:In addition to reducing blood glucose, body weight and fat mass, treatment with lilaluptide had no impact on muscle mass and muscle function. Therefore, liralutide is suitable for obese patients with type 2 diabetes, especially for weight management patients who are at risk of muscle loss.

Objective:To evaluate the characteristics of adult abdominal fat distribution and analyze its influencing factors by energy spectrum CT scan.Methods:The body height, weight, waist circumference, and hip circumference of 105 adults were measured, and the characteristics of abdominal fat distribution were evaluated by energy spectrum CT scan.Results:Compared with non-obese individuals, the contents of abdominal subcutaneous fat, abdominal cavity and liver ectopic fat were higher in obese patients ( P<0.05), and the intramuscular fat (IMAT) content did not increase with the increase of BMI. In middle-aged group, the waist circumference, waist-to-hip ratio (WHR) abdominal cavity area and IMAT content were higher than those in the youth group, and the muscle content of the middle-aged group was lower than that of the youth group, the difference between the two groups was significant ( P<0.05); the male group had higher abdominal cavity area and muscle content than the female group, while the female group had higher the subcutaneous fat area, abdominal subcutaneous fat thickness and erector spinae fat content than the male group, the differences were significant ( P<0.05). Conclusions:The characteristics of abdominal fat distribution of subjects with different BMI, age and gender were different. Therefore, we should pay attention to the individual assessment of ectopic fat distribution in obese patients. Energy spectrum CT can be used as an important approach for the assessment of ectopic fat to provide evidence for developing individualized weight loss programs.

To compare with the effects of the GM-CSF and IL-2 used as adjuvants in the baculovirus vaccine, we used genetic engineering to construct the recombinant baculovirus rBV-LMI-F and with GM-CSF and IL-2 to immunized chickens. Then, we compared the concentration of the neutralizing antibody and cytokines to determine the immunostimulatory effects of GM-CSF and IL-2. GM-CSF induced higher levels of antibodies and cytokines in chickens at 28 d and 42 d post-vaccination. In conclusion, GM-CSF could elicit higher serum antibody and cytokines responses and improved the effects of Baculovirus vaccine.

Objective To develop a nomogram for the use of predicting renal outcomes of Chinese lupus nephritis (LN) patients.Methods From January 1,2005 to October 1,2015,513 patients with biopsy-proven LN in the First Affiliated Hospital of Sun Yat-Sen University were enrolled into this study.Renal outcomes were defined as end-stage renal disease or doubling of serum creatinine.Demographic characteristics,laboratory data,and pathologic data were recorded and included for analysis.Nomograms were designed using multivariate Cox proportional hazards regression to predict the non-outcome renal survival in 5 and 8 year according to the Akaike information criterion (AIC) and continuous reclassification net improvement (cNRI).Predictive accuracy and discriminative ability of the models were determined by concordance index (C-index) and calibration curve.Results During a median follow up of 48 (24,71) months,44 patients (8.58％) reached the endpoint.1-year,5-year and 8-year non-outcome renal survival were 97.57％,92.89％,79.89％ respectively.According to multivariate Cox regression,four nomograms including index for baseline renal function,pathologic severity,and response to treatment were designed.The best model,within which included eGFR was lower than 30 ml · min-1 · (1.73 m2)-1(HR=4.44,95％ CI 2.16-9.13,P ＜ 0.01),percentage of global glomerulosclerosis was higher (HR=12.28,95％CI 3.58-42.13,P ＜ 0.01) and partial remission occurred after 6-month induction treatment (HR=9.16,95％ CI 4.71-17.82,P ＜ 0.01) demonstrated good discrimination to predict 5-year and 8-year non-outcome renal survival [C-index,0.80(95％CI 0.81-0.91),0.76(95％CI 0.68-0.85),respectively].The nomogram based on above model also performed good calibration.Conclusion The nomogram based on patients' baseline eGFR,percentage of global glomerulosclerosis,and treatment reaction after 6-month induction therapy can accurately predict 5-year and 8-year non-outcome renal survival in Chinese lupus nephritis patients.
