Objective To determine the role of valproate in the expression of SCN3A and provide new evidence for the clinical treatment of epilepsy. Methods We treated the N1E-115 cells with sodium valproate and examine the expression of SCN3A mRNA. We also constructed the expression vector of the SCN3A gene promoter then transfected the vector into N1E-115 cells ,respectively detected the level of SCN3A mRNA and the expression level of firefly luciferase of N1E-115 cells with valproate treated and untreated. Results Valproate inhibited the expression of SCN3A significantly including the level of SCN3A mRNA and luciferase protein. Conclusion Valproate inhibits the seizures by reducing the expression of the SCN3A, which provides a new understanding of the treatment of epilepsy.

OBJECTIVE:To discuss the effects of Kangshuling gel on wound treatment and infection prevention inⅡdegree burns. METHODS:60 patients with Ⅱ degree burns were randomized intro observation group and control group,with 30 cases in each group. Based on routine treatment (cleaning,disinfection,necrotic tissue removal,antibiotics use),observation group was given Kangshuling gel,and control group was treated with sulfadiazine. The average healing rate,healing time,surgical dressing exudate,inflammatory reaction around wound,the times of dressing change and inner layer gauze change,and wound infection rate were observed in 2 groups,and satisfaction survey was conducted in 2 groups. RESULTS:On 14th and 18th day after treat-ment,average rate of wound healing in observation group was significantly higher than in control group;the time of wound heal-ing was significantly shorter than control group,with statistical significance(P<0.05). Within 2 weeks after treatment,the number of gauze layer wetted by surgical dressing in observation group was significantly less than in control group,and case number of in-flammatory reaction around wound was significantly less than control,with statistical significance(P<0.05). The times of dressing change and inner layer gauze change in observation group was significantly less than in control group,and the rate of wound infec-tion was significantly less than control group,with statistical significance(P<0.05);the satisfaction of observation group was bet-ter than that of control group,with statistical significance(P<0.05). CONCLUSIONS:Kangshuling gel in the treatment of Ⅱ de-gree burns can effectively prevent and treat wound infection,reduce the rate of wound infection and the times of dressing change, shorten the time of wound healing and improve the rate of wound healing so,high satisfaction degree is obtained.

Objectives The purpose of this study is to observe the effects of valsartan on hepapetic fibrosis. Methods Thirty male Sprague-Dawley rats were randomly divided into three groups: valsartan -prevetive group (A), modle group of hepatic fibrosis (B)and valsar-tan-treating group (C). The model of hepatic fibrosis in rats was induced by intraperitoneai injection of dimethylnitrosamine (DMN) for 4 weeks(2ml/kg everyday, three times a week). Valsartan (10mg/kg everyday) was given together with injection of DMN per intrngastric (Ig) in group A for 8 weeks. After stop injection of DMN, the S valsartan(10mg/kg, everyday)was given per Ig in group C for 4 weeks. After modeling, normal saline were given per Ig everyday in group B. At the end of eighth week, the histomorphylogic structure of the liver was ob-served with light microscope. Immunohistoebemical staining was used to evaluate the expression of a-SMA. Results In group B, there was a large necrotic area and a number of pesudolobes appeared in the liver tissue. In group A, there were normal hepatic cords. In the group C, there was fibrosis interval formation and portal area expansion and fibrotie intervals extending to the lobule. The quantitative analysis of Mas-son staining showed that the collagen quantities in group B was higher than that of other group(P<0.01). The collagen quantities in group A was lower than that of group C(P<0.05). The results of immanohistochemical staining showed that the expression of a-SMA in group B was strong positive, middle positive in group C, and weak positive in group A (P<0.05). Conclusion The valsartan has preventive and treatment effects on hepatic fibrosis in rats of hepatic fibrosis model induced by DMN, and the preventive effect of valsartan is better than its treatment effect. The valsartan can ameliorate the hver cirrhosis by partly suppressing the activation of HSC.
