Aim To investigate the effects of total gin-senosides ( TG) on microvascular regeneration and car-diac function in rat after acute myocardial infarction ( AMI ) . Methods The acute myocardial infarction model was created with left coronary artery ligated in male Sprague Dawley rats. The model rats were ran-domly divided into sham, model, TG low and high dose groups. TG groups were injected into abdominal cavity with TG(20 mg·kg-1·d-1, 40 mg·kg-1· d-1 ) . Sham and model groups were injected with e-qual-volume normal saline. On the 35th day post-opera-tion, heart function was examined by color doppler ul-trasoundination. HE, Masson and immunohistochemis-trical staining were used to observe the histopathologi-cal changes of myocardium and micro vessel density. The level of vascular endothelial growth factor( VEGF) and basic fibroblast growth factor( bFGF) mRNA were detected by real-time PCR. Results Compared with the model group, high and low dose TG obviously de-creased the left ventricular end diastolic dimension, the left ventricular end-systolic dimension, the left ventric-ular end-diastolic volume and the left ventricular end-systolic volume(P<0. 05 and P<0. 01), and signifi-cantly increased the ejection fraction and the fractional shortening ( P <0. 01 ) . The histopathological changes of myocardium on myocardial infarction and fibrosis were dramatically reduced by TG. But ventricular wall was thicker. Two dose TG remarkably increased the expressions of VEGF and bFGF mRNA and micro ves-sel density of compositive CD31 + cells in ischemic myocardial tissue and around of infarct area(P<0. 01, P <0 . 0 5 ) . Conclusions TG could improve the car-diac function of acute myocardial infarction rat. The mechanism may be related to the upregulation of VEGF and bFGF gene expression, the promotion angiogene-sis, then the improvement of blood supply in myocardi-al infarction area.

Objective To evaluate the value of serum uric acid(UA)levels with reference to the age,waist circumference,and body mass index(BMI)in predicting the metabolic syndrome(MS)in obese children.Methods A total of 300 obese children,including 180 boys and 120 girls,were enrolled in this study.The height,BMI,waist and hip circumference,blood pressure,serum glucose,insulin and lipid profile in all participants were measured.Oral glucose tolerance test and insulin releasing test were performed.The boys or girls were divided into 4 groups according to the 4 quantile of UA level,respectively.The clinical characteristics and correlation of UA with the clinical indexes and MS components were compared.The binary Logistic regression analysis was applied in the risk of MS and its components for the 4 groups of obese children.The area under the receiver operating characteristic curve(ROC curve)of UA level,age,waist circumference and BMI were used to predict the MS.Results UA level was increased with the increase of age,waist circumference and BMI,and the UA level was significantly correlated with triacylglycerol,postprandial 2 h glucose(2 h PG)(r=0.196,0.174 in boys;r=0.291,0.179 in girls).In boys,the adjusted odds ratio and 95%CI of the highest quartile of UA for triglyceridemia was 2.71(95%CI:0.77-9.58);which in girls,the adjusted odds ratio and 95%CI of the highest quartile of UA for hyperglycemia,hypertension were 8.45(95%CI:1.76-40.52)and 3.93(95%CI:0.66-23.33),respectively,with significant differences.In boys,the area under the ROC curve of UA level,age,waist circumference and BMI which predict the MS were 0.652 0.626,0.621,0.62,respectively,and the differences were significant(all P<0.05).Conclusions The UA level is significantly correlated with the composition of MS,UA detection combining with reference to the age,waist circumference,and BMI is helpful for the identification of high risk groups of metabolic syndrome.

Objective:To observe the effect of abdominal electroacupuncture(EA)on intestinal function in patients with constipation after stroke. Methods:A total of 100 patients with post-stroke constipation were divided into an observation group and a control group by the random number table method,with 50 cases in each group.The control group was treated with oral lactulose,10 mL each time,3 times a day,for 2 consecutive weeks.The observation group was treated with additional abdominal EA at Tianshu(ST25),Fushe(SP13),and Daheng(SP15)on the basis of oral lactulose,30 min for needle retention each time,once a day,for 2 consecutive weeks.The total effective rate after treatment,constipation symptom score,the score of patient assessment of constipation quality of life scale(PAC-QOL),serum motilin(MTL)level,and the score of mini-mental state examination(MMSE)were compared between the two groups. Results:After 2 weeks of treatment,the total effective rate was 93.5%in the observation group and 76.1%in the control group,and the difference between the two groups was statistically significant(P<0.05).The constipation symptom score,PAC-QOL score,MMSE score,and MTL level changed significantly after treatment in both groups(P<0.05).After treatment,the constipation symptom score and PAC-QOL score in the observation group were lower than those in the control group,while the MMSE score and MLT level were higher than those in the control group,and the differences between the two groups were statistically significant(P<0.05). Conclusion:On the basis of oral lactulose,EA at abdominal points can significantly improve the intestinal and cognitive function of stroke patients simultaneously.

Objective:To investigate the status of height and weight of 3-18-year-old children and adolescents in urban China, and to provide a basis for establishing puberty phase specific curves for age-specific height and age-specific weight.Methods:A cross-sectional survey of 218 185 children and adolescents aged 3-18 years in urban China was conducted by using the method of stratified random cluster sampling from January 2017 to December 2019. The sampling areas included 12 provinces municipalities in China and autonomous regions in total. Data were collected on weight, height, waist circumference, hip circumference and secondary sexual characteristics. The generalized additive model for location, scale, and shape (GAMLSS) was employed to establish percentile reference values and growth curves of height and weight for boys and girls aged 3-18 years. Wilcoxon rank sum test was applied to compare the P 50 value of height and weight between children of each Tanner stage and children of the same age ignoring the different puberty phase. Results:The 3rd, 50th, and 97th percentile curves for height and weight for age were developed for boys and girls aged 3-18 years. The 3rd, 50th, and 97th percentile curves for age-specific height and age-specific weight for each puberty phase were developed for boys and girls. Compared with all children ignoring the different puberty phase, boys aged 9 and over and girls aged 7 and over who are at Tanner stage 1 showed shorter height and lighter weight than those of the same age group (all P<0.01), the difference ranges of height at P 50 are -4.0 to -0.6 cm for boys, and -4.4 to 0.5 cm for girls; the difference ranges of weight are -4.8 to 0.4 kg for boys, and -4.0 to -0.3 kg for girls; children at Tanner stage 2 & 3 initially were taller and heavier than those of the same age group; and later grew shorter and lighter than those of the same age group, the two sets of curves cross over; boys aged 16 and under and girl aged under 14 who are at Tanner stage 4 were taller and heavier than those of the same age group (all P<0.01), the difference ranges of height at P 50 are 0.2 to 10.0 cm for boys, and 0.2 to 9.4 cm for girls; the difference ranges of weight at P 50 are 0.7 to 10.9 kg for boys, and 1.0 to 11.2 kg for girls, and the differences showed narrowing trend with age. Conclusion:The puberty phase specific growth curves of age-specific height and age-specific weight for boys and girls aged 3-18 years are established, it is useful for clinical work to evaluate physical development of children at different puberty phases.
