Objective:To analysis the correlation of Wnt/β-catenin signaling pathway,OPN and MMP-13 in rabbit model with different degree of osteoarthritis (OA).Methods:Forty New Zealand white rabbits were randomly divided into four groups of 10 each,then we constructed the rabbit model with different degree of osteoarthritis (OA) by different concentrations of papain.The mRNA and protein levels of β-catenin,OPN,MMP-13,type Ⅱ collagen and proteoglycan were detected by Real-Time PCR and ELISA,respectively.Results:We have successfully established OA rabbit model by different concentrations of papain,and these OA rabbits model could be divided into mild,moderate and severe three level by Mankin scoring system,chondrocytes.Compared with the normal control group,the protein levels of β-catenin,OPN,and MMP-13 in the osteoarthritis were significantly increased,while the protein levels of type Ⅱ collagen and proteoglycan were significantly decreased (P＜0.05).With the increasing severity of OA,the results were consistent (P＜0.05).Conclusions:These results indicated that Wnt/β-catenin signaling pathway might regulate the expression of OPN,thereby affecting the expression of MMP-13,and ultimately have an impact on the occurrence ofosteoarthritis.

ObjectiveTo explore effect of family rehabilitation on motor function of stroke patients.MethodsTo provide family rehabilitation with community guide for 106 stroke patients, and observe therapeutic effect.ResultsFamily rehabilitation was effective on 106 cases, and the earlier therapy started, the better effect was.ConclusionFamily rehabilitation is playing an important role in treatment of stroke patients.

Objective: To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6-9 years old.Methods: A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method, with 95 cases in each group. The observation group was intervened by auricular point sticking plus guide on a healthy diet, while the control group was only provided with the guide on a healthy diet. The therapeutic efficacy was observed after intervention for three consecutive months, as well as the changes in body mass (BM), body mass index (BMI), waist circumference (WC), hip circumference (HC), and subcutaneous fat thickness. Results: After the 3-month intervention, the total effective rate was 91.6％ in the observation group, versus 74.7％ in the control group, and the between-group difference was statistically significant (P<0.01); in both groups, the BM, BMI, WC, HC, and subcutaneous fat thickness all decreased significantly (P<0.05), and were lower in the observation group than in the control group, showing statistical significance (P<0.05). Conclusion: Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children, producing more significant efficacy than healthy diet intervention alone.

This study sought to investigate the in vivo antiviral effect of amantadine (AM) and biphenyl dimethyl dicarboxylate (DDB) on hepatitis B virus (HBV) in HBV replication mice. HBV replication-competent plasmid was transferred into male BALB/c mice by using hydrodynamics-based in vivo transfection procedure to develop HBV replication mouse model. The model mice were matched by body weigh, age and serum levels of hepatitis B e antigen (HBeAg) and were divided into four groups: AM group, DDB group, AM+DDB group and NS group, with the last one as control, and the mice of each group were administered corresponding agent orally twice a day, in a medication course lasting 3 d. On the third day, the mice were sacrificed 4-6 h after the last oral intake. HBV DNA replication intermediates in liver were analyzed by Southern blot hybridization. The serum hepatitis B surface antigen (HBsAg) and HBeAg were detected by enzyme linked immunosorbent assay (ELISA). Compared to the animals in the control group, HBV DNA replication intermediates in liver and HBsAg and HBeAg in serum from the AM and AM plus DDB group of mice decreased, and there was no difference between these two groups of mice. The levels of HBV DNA intermediate from liver and the serum HBsAg and HBeAg between the control and DDB group, however, were not obviously different. In conclusion, the inhibition effect of AM on HBV was detected, but treatment with DDB for 3 days did not influence the viral replication and expression of HBV in the HBV replication mice.

Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

OBJECTIVE:To evaluate the curative effect and safety of reduced glutathione for injection(Atomolan) on the Alcoholic Liver Disease(ALD).METHODS:This was a randomized,placebo controlled study,in which the reduced glutathione for injection(Gluthion) was used as control substance.A total of 261 ALD patients were randomly divided into 2 groups in 1:1 ratio(trial group,n=135;control group,n=126).The dosage,route and course of treatment in two groups were the same.Clinical data including biochemical parameters,symptoms and signs in two groups were monitored.RESULTS:The excellent effective rate,effect rate and total effective rate in the trial group were 58.5%,23.7% and 82.2%,respectively,those in the control group were 57.9%,22.2% and 80.2%,respectively,showing no significant difference between the 2 groups(P=0.90).CONC-LUSION:The study showed that the domestic glutathione for injection had a sound efficacy in improving clinical symptoms and recovery of liver biochemical parameters,showing equivalent efficacy to the control preparation good safety.
