Objective To study the effect of Nurrl gene on the differentiation of rats' marrow stromal cells(MSCs) into neurous under the co-inducement of total panax notoginserg saponins(tPNS) and all-trans-retineic acid(ATRA) by coloning the Nurrl gene and transfecting it into MSCs. Methods Expressing plasmids pcDNA3.1-hygro-Nurrl were cloned,then transfected into MSCs with lipofectamine 2000.To begin with,MSCs were subcultured into 6-wells cultured plate at about 5?10~5 cells/well density and the wells were divided into four groups randomly which were Nurrl+tPNS/ATRA group,tPNS/ATRA group,Nurrl group and control group.Secondly,the plasmids were introduced to the MSCs in Nurrl+tPNS/ATRA group and Nurrl group,then protein expression of Nurrl was identified with immunocytochemistry.Thirdly,after the MSCs and plasmids had been co-cultured for 48 hours,cells in Nurrl+tPNS/ATRA group and tPNS/ATRA group were induced with BME in advance then with tPNS/ATRA in due form.For cells in Nurrl and control group,the only difference was that tPNS/ATRA was replaced with the culture.Finally we compared the different percentage of positive cells in four groups with TH,AChE and GABA antibodies by immunocytochemistry method. Results The immunocytochemical test showed that the MSCs transfected with Nurrl gene expressed Nurrl protein.The percentage of positive cells of TH antibody in Nurrl+tPNS/ATRA group was(38.4?4.6)% distinctly higher than that of tPNS/ATRA group,which was(5.9?3.4)%.Conclusion With tPNS/ATRA induced and immunocytochemistry of TH,positive cells percentage in Nurrl+tPNS/ATRA group was higher than that in tPNS/ATRA group,which showed a statistic difference.And the inducing function of tPNS and ATRA in MSCs differentiating into neurons was definite.

OBJECTIVE:To observe clinical efficacy and safety of intraarticular injection of betamethasone and hyaluronate in the treatment of elderly knee osteoarthritis. METHODS:A total of 76 elderly patients with knee osteoarthritis were selected from our hospital during Jul. 2012 to Jul. 2015,and then divided into control group and observation group according to random number table,with 38 cases in each group. Control group was given intraarticular injection of Sodium hyaluronate injection 2 mL,once a week,for consecutive 3 weeks. Observation group was given Compound betamethasone injection 1 mL in the first week,and given sodium hyaluronate 2 mL,every week,in the following 2 weeks. Clinical efficacies and the occurrence of ADR as well as VAS score,WOMAC score,GQOLI-74 score and MMP levels before and after treatment were compared between 2 groups. RESULTS:Total response rate of observation group was 92.11％,which was significantly higher than 73.68％ of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in VAS score,WOMAC score,GQOLI-74 score, MMP-1 level or MMP-3 level between 2 groups(P>0.05). After treatment,VAS,joint stiffness,joint pain and daily activity re-striction score as well as MMP-1,MMP-3 were decreased significantly in 2 groups,compared to before treatment;physical pain, physiological function,physiological limitations,vitality,social function,emotional function,mental health and GQOLI-74 total score were increased significantly,and the each index of observation group was significantly better than that of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:The intraarticular in-jection of betamethasone and sodium hyaluronate in the treatment of elderly knee osteoarthritis can effectively reduce pain degree, improve knee function and quality of life,have good therapeutic efficacy and safety,the mechanism of which may be associated with the reduction of MMP level.

MicroRNAs (miRNAs) are small endogenous non-coding RNA molecules.They regulate negatively the expression of target genes at post-transcriptional stages by means of affecting the stability of target mRNA or interfering with the transcriptional process.Recently,there is evidence demonstrating that miRNAs play important roles in the gene expressions of thyrotoxic heart diseases.Elevated levels of thyroid hormones profoundly influence the cardiovascular system through the renin-angiotensin system (RAS).As a principal active component of RAS,angiotensin Ⅱ receptor 1 (AT1 R) interacts with miRNAs in promoting or extenuating the progress of thyrotoxic heart disease.In this article,the roles of AT1R-associated miRNAs,miR-21,miR-155,miR-208a/b,and miR-499 in thyrotoxic heart disease were reviewed.

Objective To observe the effects of exercise training on the expression of glycogen synthase ki-nase-3 (GSK-3) in the skeletal muscles of rats with insulin resistance induced by a high-fat and high sucrose diet. Methods Thirty Wistar rats were randomly divided into three groups: a control group, a model group and an exercise group. Rats in the model and exercise groups were fed with a high-fat and sucrose diet (20% sucrose, 10% lard, 2.5% cholesterol, 1% cholic acid) for 4 weeks, and then the rats in the exercise group were trained by swimming 5 d every week for 6 weeks. After treatment, the concentration of GSK-3 protein in their muscles was detected by Western blot analysis, while their weights, serum triglyceride and total cholesterol, and their concentrations of fasting plasma glucose and fasting plasma insulin were measured periodically and their insulin sensitivity index was calculated. Results Compared with the controls, the expression of GSK-3 in the skeletal muscles of the rats in the model group increased by 70. 20% (P
