With the rapid development of population aging in various countries around the world,the health and elderly care industry has been paid high attention.The standardization of smart health and elderly care technology and services is particularly important.This paper firstly reviewed the policies related to healthy elderly care in China.By analyzing the industrial standards and provincial standards issued,this paper focused on the policies proposed by the Shanghai Municipal Government for the standardization of smart health and elderly care,as well as the researches on the standard system and the construction of standard families.Shanghai group standards in the field of smart health and elderly care were summarized,including the guidelines for the construction of standard systems,elderly care service platforms,community elderly cafeterias,portable health monitoring terminals,indoor sports services,and home-based elderly care safety monitoring.A series of case analyses of the standardized implementation of the above aspects were also provided.Through standardization research and practice in recent years,it has been fully demonstrated that the standard research plays an important leading role in the field of smart health and elderly care.

Objective:To investigate the age-specific distribution characteristics of plantar pressure parameters in healthy children aged 3-12 years.Methods:This cross-sectional study retrieved data from the hospital information system in January 2025 for 272 children aged 3-12 years who underwent physical examinations and voluntarily completed plantar pressure analysis at Beijing Children′s Hospital, Capital Medical University, from July 2022 to December 2024. Demographic and clinical data, including anthropometric measurements (height and weight), flatfoot diagnosis and plantar pressure parameters (maximum pressure, time to maximum force, and contact time percentage in bilateral forefoot, midfoot, and hindfoot) were recorded. Participants were categorized into 3 age groups (3-6 years, 7-9 years, and 10-12 years) and were grouped by gender as well. Intergroup comparisons used one-way ANOVA or least-significant difference test or χ2 tests. Spearman′s rank correlation assessed the relationship between flatfoot prevalence and age. Results:Among 272 children (143 boys, 129 girls), age groups comprised 3-6 years (118 children, 64 boys and 54 girls), 7-9 years (96 children, 49 boys and 47 girls), and 10-12 years (58 children, 30 boys and 28 girls). Flatfoot prevalence was higher in boys than in that of girls (41.3% (59/143) vs. 28.7% (37/129), χ2=4.70, P=0.030), and negatively correlated with age ( r=-0.21, P<0.001). There all had statistically differences in the maximum pressure values of the bilateral forefoot and hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). The maximum pressure values of bilateral midfoot in the group of aged 10-12 years were all higher than those of the other two groups (all P<0.001). There had no statistically differences in the time maximum force value of the bilateral forefoot among the 3 age groups (all P>0.05). The time maximum force values of bilateral midfoot in the group of aged 3-6 years were all lower than those of the other two groups (all P<0.05). There all had statistically differences in the time maximum force value of the bilateral hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). There all had statistically differences in the contact time percentage values of the bilateral forefoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). There had no statistically differences in the contact time percentage values of the bilateral midfoot among the 3 age groups (all P>0.05). There all had statistically differences in the contact time percentage values of the bilateral hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all lower than those of the other two groups (all P<0.05). Conclusion:Plantar pressure parameters exhibit distinct age-related patterns, reflecting the development of gait patterns and foot arch formation, which will be useful for monitoring physical growth and sports rehabilitation.

Objective : To investigate the molecular mechanism of Toll⁃like receptor 4 ( TLR4)/Ras homologue A (RhoA) signaling pathway involved in regulating the effect of septic serum on vascular endothelial cell permeability before and after continuous hemofiltration. Methods : The serum of 5 patients with sepsis before and after continuous hemofiltration treatment was collected , and the levels of inflammatory cytokines in serum before and after hemofiltration were detected. Human umbilical vein endothelial cells (HUVEC) were treated with serum before and after continuous hemofiltration for 24 hours. The expression of VE⁃cadherin , F ⁃actin , TLR4 and RhoA in vascular endothelial cells were detected by Western blot. A TLR4 low expression cell line was constructed to detect the effect of TLR4 low expression on the expression of VE⁃cadherin , F ⁃actin and RhoA and the permeability of endothelial cells. Results : After continuous blood treatment , the serum levels of TLR4 , RhoA , interleukin⁃1 (IL⁃1) , interleukin⁃6 (IL⁃6) and tumor necrosis factor⁃α (TNF⁃α ) significantly decreased. The expression levels of VE⁃cadherin , F ⁃actin , TLR4 and RhoA in the serum intervention group after continuous hemofiltration treatment significantly decreased , and the cell permeability significantly decreased. Low expression of TLR4 significantly promoted the expression of VE⁃cadherin and F ⁃actin , and inhibited the expression of RhoA protein. Conclusion TLR4/RhoA signaling pathway is involved in the regulation of changes in vascular endothelial cell permeability induced by septic serum after continuous hemofiltration treatment.

Objective: To compare the therapeutic effect of aspirin and clopidogrel on coronary heart disease. Methods: From June 2016 to July 2017, 186 patients with coronary heart disease in the Third People's Hospital of Yuyao were divided into control group and observation group according to different treatment methods, with 93 cases in each group.Both two groups were treated with routine symptomatic therapy, the control group was given aspirin and the observation group was given clopidogrel.Biochemical indicators, cardiac function and adverse events were observed. Results: There were no statistically significant differences between the two groups before treatment(all P>0.05). The platelet aggregation rate and activation time of partial thrombin of the observation group were (38.11±2.15)% and (48.21±3.50)s, respectively, which were better than those of the control group(t=48.819, 18.752, all P<0.05). There were no statistically significant differences in prothrombin activity and prothrombin time between the two groups(all P>0.05). The probability of grade Ⅳ and grade Ⅰ in the observation group was 8.60% and 38.71%, respectively, which was significantly different from those in the control group(χ²=5.243, 6.541, all P<0.05). The incidence rate of adverse events in the observation group(1.08%) was lower than that in the control group(7.53%), and the difference was statistically significant(χ²=4.072, P<0.05). Conclusion Clopidogrel is more effective than aspirin in the treatment of coronary heart disease.It can significantly improve the coagulation function, cardiac function, and it is safe and with less adverse reactions.

OBJECTIVE: To explore the relationship between serum IL-4, IFN-gamma, IL-10 levels and the aetiology of juvenile-onset recurrent respiratory papillomatosis. METHOD: Serum IL-4, IFN-gamma, IL-32 levels of 15 JORRP children were detected by use of enzyme-linked immunosorbent assay (ELISA) and compared with those of healthy control group. RESULT: Serum IL-4 levels were significantly higher in the JORRP children (P<0.01): (524.65 +/- 147.77)pg/ml in the JORRP children and (213.27 +/- 87.48) pg/ml in the healthy control group. Serum IFN-gamma levels were significantly lower in the JORRP children (P<0.01): (2.87 +/- 0.84) pg/ml in the JORRP children and (10.63 +/- 5.09) pg/ml in the healthy control group. Serum IL-32 levels were significantly lower in the JORRP children (P< 0.01): (2.47 +/- 1.60) pg/ml in the JORRP children and (9.08 +/- 2.66) pg/ml in the healthy control group. CONCLUSION 1) While the concentration of Th2 like cytokine IL-4 in children with JORRP was higher than that in control group, the concentration of Th1 like cytokine IFN-gamma in children with JORRP was lower than that in controls, indicating that the polarization of Th1 /Th2 T cell in children with JORRP; 2) The polarization of Th1/Th2 T cell may cause the reduction of the serum IL-32 as a proinflammatory role in host immunity system that could not eradicate HPVs because of lacking enough inflammatory stimulation.
