OBJECTIVE: To probe into the status quo and future tendency of utilization of cardiovascular drugs in hospital of high altitude area. METHODS: Consumption sum and DDDs of cardiovascular drugs used in our hospital were analyzed statistically during 2006~2008. RESULTS: Consumption sum of cardiovascular drugs was increased year by year as well as its percentages in the total consumption sum. Top 10 cardiovascular drugs in terms of consumption sum mainly included antianginal drugs, antihypertensive drugs, blood fat harmimegathy drugs and antithrombotics drugs. Consumption sum of antianginal drugs which had occupied 44% in that of cardiovascular drugs took the dominate place in three years. Consumption sum of antihypertensive drugs was increased fast as well as its percentage in cardiovascular drugs about more than 20%. Consumption sum of antithrombotics drugs had occupied about 22%. CONCLUSION: Requirement of cardiovascular drugs was increased year by year. Cardiovascular drugs from foreign countries and joint stock take main place. It is necessary to explore domestic substitute drugs to decrease the cost of cardiovascular drugs.

AIM To study antitumor activity of the extract denominated as UAP(Uric Antitumor Peptides isolated and purified from normal human urine). MOTHODS Proliferation inhibition assay was examined by cell counting and MTT method. Experiments in vivo were tested by treatment on tumor mice and acute toxicity on healthy mice. RESULTS UAP exerted strong dose dependent inhibition on the proliferation of three tumor cell lines, but not human normal leucocytes. Treatments on tumor mice show that UAP effectively inhibited tumor growth of mice HAC hepatoma, mice Lewis lung carcinoma and mice S 180 sarcoma with apparently dose dependent effect. Acute toxicity proved that UAP had very low acute toxicity in mice with LD 50 = 2 137 13 mg?kg -1 . CONCLUSION UAP has strong antitumor activity in vitro and in vivo. This provides a promising alternative antitumor treatment.

BACKGROUND:Core decompression can delay early osteonecrosis of the femoral head, but cannot completely repair the necrotic femoral head. Eventualy, femoral head colapse, even bone necrosis, wil occur. OBJECTIVE:To explore the curative effect of implantation of gelatin sponge carrying Foxc2-transfected bone marrow mesenchymal stem cels on the repair of experimental femoral head necrosis in rabbits. METHODS:Forty New Zealand white rabbits were selected, and femoral head necrosis models were prepared successfuly in 24 of 40 rabbits. Then, model rabbits were randomized into four groups: blank control group (n=4) with no treatment, core decompression group (n=4), GFP group (n=8) subjected to core decompression and implantation of gelatin sponge carrying GFP-transfected bone marrow mesenchymal stem cels, and Foxc2 group (n=8) subjected to core decompression and implantation of gelatin sponge carrying Foxc2-transfected bone marrow mesenchymal stem cels. At 1, 2, 4 weeks after implantation, ELISA was used to detect Foxc2 protein levels in the transplanted region. At 4, 8, 12 weeks after implantation, MRI scan of the hip was performed, and femoral head tissues were taken and sliced into sections for hematoxylin-eosin staining to observe bone growth. At 12 weeks after implantation, histomorphometry measurement and transmission electron microscope observation were carried out. RESULTS AND CONCLUSION:At 1, 2, 4 weeks after implantation, Foxc2 was highly expressed in the femoral head in the Foxc2 group, which was significantly higher than that in the GFP group. At 4, 8, 12 weeks, only a few of new bone formed in the core decompression group and GFP group; at 12 weeks, fibrous tissues formed in the decompression channel. New bone formation was evident in the Foxc2 group, and at 12 weeks, the necrotic region was repaired completely. MRI findings showed normal femoral head morphology and signals in the Foxc2 group at 12 weeks, but there were decreased signals of the femoral head in the core decompression group and GFP group. These findings indicate that Foxc2-transfected bone marrow mesenchymal stem cel transplantationvia core decompression has good curative effects on experimental femoral head necrosis in animals.
