Objective To investigate the effects of new compound traditional Chinese medicine prepatations Banxiao capsule on the mobilization of endothelial progenitor cells ( EPCs) .Methods After EPCs from mouse bone marrow treated with variable dose of Banxiao capsule, we detected the proliferation by CCK-8 assay, quantified the number of CD34/Flk-1 double positive cells by flow cytometric analysis, evaluated the migratory function of EPCs by transwell chamber assay, and studied the protein level of Bcl-2/Bax by Western blot analysis.Results Compared with untreated group, the proliferation potential of EPCs in Banxiao low dose (20μg/ml) and high dose (200μg/ml) group was increased(P<0.05), the number of CD34/Flk-1 double positive cells were increased (P<0.05), migrative activity of EPCs was increased (P<0.05),the level of Bcl-2 protein were increased, and the level of Bax protein were decreased.Con-clusion Banxiao capsule can enhance proliferation of EPCs through up-regulating of expression of Bcl-2/Bax.

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.

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

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 effects of hyaluronidase (HAase) and hyaluronan (HA) on proliferation of vascular endothelial cells and its mechanism. Methods: The cultured bovine aortic endothelial cells (BAEC) were treated with HAase or HA. Cell proliferation rate was detected by MTT assay. The expression of CD44 and DNA content of the cells were measured by flow cytometry (FCM). Results: HAase (50 ?g/ml) stimulated cell proliferation [(50.10? 1.23)% vs control, P

Objective: To investigate the influence of mental stress on platelet function in patients received coronary angiography(CAG). Methods: With flow cytometry the expressions of platelet membrane glycoproteinⅡb Ⅲa complex ? subunit(CD41) and P selectin(CD62p) were measured in 24 CAG patients before,immediately after and 10 min after mental stress, respectively. Results: Compared with that before mental stress, the positive rate of CD41 [from(74.15?22.24)% to (87.41? 9.24)%, P

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.

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 OX-LDL on the formation and progression of atherosclerosis. Methods: (1) The thoracic aorta smooth muscle cells(VSMC) of male Sprague-Dawley rat were primarily cultured in vitro. Different concentrations of OX-LDL(50,100,150,200 ?g/ml) were co-incubated with the cells respectively. MTT method was used to detect the cell proliferation after 24, 48 and 72 h. (2) pCOLH22. 4 and pCOLH2l. 6, recombinants of human a2( I ) procol-lagen gene 5' flank sequence ( - 2. 4 kb and -1. 6 kb in size) and CAT reporter gene, were used to transiently transfect smooth muscle cells with FuGENE Transfectant Reagent. The effect of OX-LDL (150 ?g/ml) on the plasmid were determined by CAT-EL1SA. Results: (1)OX-LDL accelerated the proliferation of VSMC in dose-dependent manner. (2)OX-LDL enhanced the promoter activities of human a2( I ) procollagen gene significantly. Conclusion: OX-LDL can accelerate the proliferation of VSMC and the formation of type I collagen,which facilitates the formation and progression of atherosclerosis.
