0.05 ). CONCLUSION: Liduofen is an effective and safty drug inthe treatment of patients with osteoarthritis of the knee joint. There is no significant difference on efficacy and safety between the two groups using liduofen and Olfen 75.

AIM: To investigate the efficacy and safety of liduofen in the treatment of patients with osteoarthritis of the knee joint. METHODS: A randomized, double-blind, parallel-controlled, multi-centre study was adapted to compare the efficacy and safety between liduofen and Olfen-75 in 136 patients. Patients were randomly assigned into two groups: liduofen group which was received 75 mg (diclofenac) Liduofen injection (n=69) once a day for seven days and Olfen group which was received 75 mg (diclofenac) Olfen-75 injection (n=67) once a day for seven days. RESULTS: After the treatment, similar improvements for rest pain, pain on exercise, swelling of joint, pressing pain of joint, knee joint bend extend function measured using a 10 cm visual analogue scale was performed in two groups. In Olfen-75 group, the rate of efficacy was 62.69% in the 3rd day, 95.76% in the 5th day and 97.88% in the 7th day. While in liduofen group, the rate of efficacy was 57.97% in the 3rd day, 93.87% in the 5th day and 96.94% in the 7th day. In liduofen and Olfen-75 groups, the progressive rates were 56.72% and 55.07%, respectively. The total improvement rates were 89.85% and 92.54% respectively (P＞0.05), and the rates of side effects were 0% and 1.49%, respectively (P＞0.05). CONCLUSION: Liduofen is an effective and safty drug inthe treatment of patients with osteoarthritis of the knee joint. There is no significant difference on efficacy and safety between the two groups using liduofen and Olfen-75.

Medication is still the main means for treating liver cirrhosis. However, micro-circulation obstacle in the liver and dynamic abnormality of portal vein flow suggest that liver protecting drugs via peripheral veins can hardly give full requirement for their effect. The authors reviewed a new method of percutaneous transhepatic portal vein implantation of port-catheter system for infusion of drugs in the treatment of liver cirrhosis, with theoretical basis and the outlook of application.

Objective To investigate the change of anxiety in patients undergoing coronary angiography. Methods The Spielberger State-Trait Anxiety Inventory was carried out in hundred and forty five patients, 104 men, 41 women, mean age (63?9) years, before and after the coronary angiography procedure respectively. Results The state anxiety score after the procedure was significantly decreased from 35.8?10.2 to 31.7?9.9(P

BACKGROUND:Recent studies have found that long non-coding RNAs (lncRNAs) can regulate stem cel proliferation and differentiation. But it is unclear that how lncRNA NR_033474 regulate stem cel proliferation and cel cycle. OBJECTIVE:To investigate the effect of lncRNA NR_033474 on the proliferation and cel cycle regulation in C3H10T1/2 mesenchymal stem cel s after the NR_033474 overexpressed by lentivirus, and to study the possible regulation mechanism of NR_033474 on mesenchymal stem cel s. METHODS:LncRNA NR_033474 was cloned into a lentivirus vector. Lentivirus particles were infected into C3H10T1/2 cel s to upregulate the expression of NR_033474. The NR_033474 expression level was detected by real-time PCR. Compared with the empty lentivirus vector, the proliferation of C3H10T1/2 cel s which overexpressed NR_033474 was detected by cel counting assay and cel cycle was detected using flow cytometry. The expression of cel cycle-associated proteins such as CDK1, Cyclin B1, Cyclin D1 and P53 were detected by western blot assay. RESULTS AND CONCLUSION:Compared with the control group, lncRNA NR_033474 in C3H10T1/2 cel s which overexpressed NR_033474 was increased by about 100 times (P<0.01), and the proliferation of C3H10T1/2 cel s was significantly inhibited after NR_033474 overexpression by lentivirus (P<0.05). In addition, flow cytometry showed that C3H10T1/2 cel s overexpressing NR_033474 were arrested in G2/M phase compared to the control group. Western blot showed that the expression levels of CDK1 and Cyclin B1 were downregulated, while there were no changes in Cyclin D1 and P53 expression. To conclude, these findings suggest that the NR_033474 overexpression significantly inhibits the cel growth of C3H10T1/2 cel s, at least in part, through induction of cel cycle arrest at G2/M phase.

Objective: To explore the regulative role of extracellular regulated protein kinase-5 (ERK5)/Bcl-2 interacting mediator of cell death (Bim) pathway in hypothermal stimulation induced neonatal rat’s cardiomyocytes (CMs) damage and apoptosis.
Methods: CMs were cultured for hypothermal stimulation and the speciifc siRNA was used to down-regulate the ERK5 or Bim in CMs. The cell apoptosis was detected by lfow cytometry, protein expression was examined by Western blot analysis, the intracellular Ca2+, reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm) were evaluated by lfuorescent labeling and lfow cytometry.
Results: In hypothermal stimulated CMs, ERK5 siRNA could promote Bim protein expression, but Bim siRNA could not inlfuence ERK5, while attenuated p-ERK5 expression. ERK5 siRNA induced higher apoptosis rate, while Bim siRNA could decrease such effect. ERK5 siRNA increased the intracellular Ca2+overloading, ROS activation andΔΨm damage, while Bim siRNA played the role to against those effects in hypothermal stimulated CMs.
Conclusion: Our study revealed that ERK5/Bim pathway played the important regulative roll in hypothermal stimulation induced neonatal rat’s CMs damage and apoptosis.

Objective: To investigate the effects of hyaluroni dase (HAase) and hyaluronan (HA) on proliferation of vascular endothelial cells and its mechanism. Methods: The cultured bovine aortic endothel ial cells (BAEC) were treated with HAase or HA. Cell proliferation rate was dete cted by MTT assay. The expression of CD44 and DNA content of the cells were meas ured by flow cytometry (FCM). Results: HAase (50 μg/ml) stimula ted cell proliferation ［(50.10±1.23）% vs control, P<0.01］, incre ased S phase cell rate and induced the expression of CD44, but HA (100 μg/ml) i nhibited cell proliferation and the expression of CD44. Conclusion: HAase may degrade antiangiogenic HA of extracellular matrix, which may stim ulate proliferation of endothelial cells and enhance the curative effect of grow th factors to myocardial ischemia.
