Objective To evaluate the angiogenic effect of the bone marrow mesenchymal stem cells (MSCs) transfected with adeno-associated virus (rAAV) -mediated human vascular endothelial growth factor 165 (VEGF165) gene, to detect the expression and bioactivity of VEGF in the MSCs.and to detect the expression and bioactivity of VEGF165 gene in the area of ischemic skeletal muscle in rats. Methods The MSCs were cultured by whole bone marrow culture method, then the MSCs were transfected with rAAV-VEGF165, the expression of VEGF was examined using ELISA and RT-PCR. The model of ischemic skeletal muscle was established by ligation in inbred rats. The rats were injected with PBS at the ischemic zone (group A), MSC (group B), hVEGF-transfected MSC (group D), and 7 days later they were injected with hVEGF transfected MSC (group C). Six weeks after the transfection, the capillary density of the ischemic zone was examined by factor Ⅷ stain. Results The MSCs were cultured successfully according to the expressions of positive CD44 and CD90,negative CD34. In rAVV-VEGF165 transfected group, the secretion levels of VEGF165 in supernatant were significantly higher than in non-transfected group 1,3,5,7 and 9 days after injection [(131. 98±6.00) ng/L vs. (68. 72±1.99) ng/L; (263. 96±4.58) ng/L vs. (76. 47±4.98) ng/L;(540. 85±5.97) ng/L vs. (89. 86± 1.99) ng/L; (208. 98± 5.06) ng/L vs. (84. 93±8. 97) ng/L;(174.45±5.00) ng/L vs. (68.71±5.98) ng/L, all P＜0.05]. On the position of 579 bp, highbrightness strip could be seen. There were no significant differences in growth curve and cell morphology between transfected group and non-transfected group. Six weeks after the transplantation, the capillary density was significantly greater in group D [(9.35 ± 2.72)/ vision]than in group A [(1. 05±0. 50)/vision] ,group B [(3.10± 1.43)/vision, both P＜0. 01)] and group C [(6. 95± 1.69)/ vision, P＜0. 05] Conclusions MSCs are helpful for the stable expression of hVEGF gene, and it is good cellular vehicle for VEGF genes. The effect of combined therapy is much better than separate transplantation of MSCs. The best time to transplant is 10 days after surgical operation.

Fifty-six hypertensive diabetic patients (glyeosylated hemoglobin A1c<7%)with albuminuria were randomly assigned to benazepril (10 mg/d,n=28) or amlodipine (5 mg/d,n=28) group.Blood pressure was measured at the end of 4-week treatment.Benazepril and amlodipine were increased to 20 mg/d and 10 mg/d respectively when blood pressure>130/80 mm Hg.All the patients were treated for 12 weeks.In both groups,plasma yon Willebrand factor and urine albumin decreased significantly from baseline.Except for urine albumin,no significant inter-group difference in plasma van Willebrand factor and target blood pressure was observed.Benazepril and amledipine seem to show similar efficacy in lowering blood pressure and improving endothelial function,but benazepril may be more effective in kidney protection.

A total of 100 patients with subacute thyroiditis hospitalized from January 2011 to October 2012 were recruited.Each received glucocorticoid treatment for 8 weeks and there was a 2-month follow-up period after drug withdrawal.After treatment,the short-term recurrence rate was 34％ (34/100).If thyroid ultrasound was abnormal,the recurrence rate was 52％ (30/58).And it was significantly higher than 10％ recurrence rate for those with normal thyroid ultrasound (4/42,x2 =9.67,P ＜ 0.01).The recurrence rate of different erythrocyte sedimentation rate groups of 40-100 mm/1 h and ＞ 100 mm/1 h was 37％ (22/60) and 30％ (12/40) respectively (P ＞ 0.05).

Objective To investigate the correlation of anthropometric indicators and blood pressure in children. Methods A total of 6 790 children aged 6 to 13 years were inspected by random sampling. The body mass index (BMI), waist circumference (WC), hip circumference (HC), and blood pressure were measured. The waist/hip ratio (WHR) and waist/height ratio (WHtR) were calculated. The data wrer analyzed by SPSS16.0 statistical software. Results The detection rate of hypertension in children was 5.57%. After controlling for age, both in male and female children, the BMI, WC, HC, WHR, WHtR and systolic blood pressure showed a significant positive correlation by partial correlation analysis (all P<0.05). Both in male and female children, the BMI, WC, HC, WHR, and WHtR were significantly higher in children with hypertension than those in children with normal blood pressure (all P<0.05). Among all subjects, 280 children (4.12%) were obese, 622 children (9.16%) were overweight. The detection rates of hy-pertension were significantly different among obese, overweight and normal weight children (P<0.01). The detection rate of hypertension was significantly higher in obese children than that in overweight and normal weight children. The systolic and diastolic blood pressure were all significantly higher in obese and overweight children than that in normal weight children (P<0.05). Conclusion The hypertension prevalence of children aged 6 to 13 years in Zhengzhou is in the low to median level in the same age groups. The BMI, WC, HC, WHR, WHtR are signiifcantly correlated with blood pressure in both gender, and the correlation is the most obvious in HC.

Objective To study the changes of transforming growth factor-β1(TGF-β1) in pulmonary fibrosis induced by paraquat (PQ) with immunohistochemistry method. MethodsA total of 58 C57BL/6J male mice were randomly (random number) divided into the experimental group and control group. Pulmonary fibrosis was induced by intra-peritoneal injection of PQ in dose of 10 mg/kg into the mice of experimental group (n = 48), while physiological saline was used instead in mice of control group (n = 10). The mice of experimental group were sacrificed 2, 5, 7 and 14 days after PQ poisoning and the mice of control group were sacrificed on the 7th day after saline administration. Lungs of mice were taken and histological changes in lungs were evaluated by haematoxylin-eosin stain, and TGF-β1 was determined with immunohistochemistry method. The integrated optical density (iOD) value of TGF-β1 was measured and analyzed. ResultsThe TGF-β1 was markedly increased in macrophages during the genesis of pulmonary fibrosis induced by PQ. As the course of fibrosis progressed, the positive staining of TGF-B1 was mainly seen in macrophages and neutrophil's cytoplasm. On the 14th day after PQ poisoning, TGF-β1-positive cells were also detected in the fibroblast and myo-fibroblast inside the fibroblastic foci. Compared with the control group, the iOD value of TGF-β1 increased in experimental group (P ＜ 0. 01 ) and it gradually upgraded during the course of fibrosis. Conclusions The TGF-β1 significantly increased during the course of pulmonary fibrosis induced by PQ and played an important role in the pathogenesis of the disease.

A rapid resolution liquid chromatography coupled with quadrupole-time-of-flight mass spectrometric (RRLC-Q-TOF-MS) method was established and optimized for the analysis of pharmacokinetic behavior of ginsenoside Rb2 in rats by intravenous injection administration.The metabolism of ginsenosides Rb2 in vivo rat was also explored.In the experiment,Agilent SB C18 column was selected for the sample separation with 0.1％ aqueous formic acid solution as mobile phase (A) and acetonitrile as mobile phase (B) at a flow rate of 0.2 mL/min,and the injection volume was set to 5 μL.Q-TOF-MS was carried out in electron pray ionization (ESI) negative ion mode.The limit of quantification (LOQ,S/N =10) and limit of detection (LOD,S/N=3) were 0.10 and 0.08 μg/mL,respectively,and the linear range was 0.1-1.26 μg/mL.The experiment results showed that the concentration-time profile of ginsenoside Rb2 conformed to a two-compartment pharmacokinetic model after intravenous administration for rats.The mean plasma elimination half-lives were (23.58±1.10) min (t1/2α),(1306.55±147.23) min (t1/2β) for Rb2.By analyzing the urine of rats after intravenous administration and the fecal samples after oral administration of ginsenoside Rb2,it was found that the metabolites were M6,M2 (CY),F2,and C-K.
