ABSTRACT
Objective To investigate the effects of ultra-filtration extract from the mixture of Angelicae Sinensis Radix and Hedysarum Polybotrys (UFE-AH) on the expressions of HSP70 and eNOS in H2O2-induced endothelial cell apoptosis. Methods H2O2 induced ECV-304 cell apoptosis to prepare models. The experiment was divided into normal control group, model group, simple medicine group, medicine intervention group, and all treatment groups received relevant medicine for intervention. Flow cytometry (FCM) was used to detect apoptosis and concentration of intracellular Ca2+;RT-PCR was used to detect the mRNA expression of HSP70 and eNOS;Western blot was used to detect the expression of HSP70 protein;Nitrale reduetase and spectrophotometric method were employed to detect the content of NO. Results Compared with normal control group, cell apoptosis rate, concentration of intracellular Ca2+, and expression of HSP70 increased significantly in model group (P<0.05);gene expression of eNOS mRNA and content of NO decreased (P<0.05). Compared with model group, cell apoptosis rate and concentration of intracellular Ca2+dropped in medicine intervention group (P<0.05);expressions of HSP70, eNOS mRNA and content of NO increased (P<0.05). Conclusion UFE-AH can confront H2O2-induced cell apoptosis H2O2 of ECV-304 human umbilical vein endothelial by increasing the expressions of HSP70 and eNOS and content of NO, and reducing the intracellular calcium overload.
ABSTRACT
Objective To observe the therapeutic effect of Chinese medicine in treating elderly herpes zoster, and study the clinical evaluation of the treatment with Chinese medicine from evidence-based medicine (EBM) view. Methods All the 156 elderly patients diagnosed with herpes zoster were randomly divided into treatment group (78) and control group (78). The former group was administered with Chinese medicine by oral administration and topical application, while the latter took aciclovir alone. All the case were treated for 10 days. Results The overall response rates of Chinese medicine and aciclovir in treatment herpes zoster were respectively 98.70% and 84.62% (P
