Objective To investigate the effects of Tongmai Tang on the production of nitric oxide(NO) and the balance of fibrinolysis system in human umbilical vein endothelial cells(HUVEC) injured by oxidized low density lipoprotein(oxLDL). Methods The herbage-contained serum of Tongmai Tang and oxLDL were prepared, then the human HUVEC-304 cells were divided into 4 groups: ⑴control group; ⑵bovine serum control group; ⑶oxLDL group: 100mg/L oxLDL, and ⑷Tongmai Tang group: 5% herbage-contained serum of Tongmai Tang and 100mg/L oxLDL. After 24h incubation, the morphology of the endothelial cells was observed under the inversion microscope, while the concentrations of NO, t-PA and PAI-1 in the culture medium were measured. Results ⑴The endothelial cells in oxLDL group were seriously injured, while those in Tongmai Tang group got better; ⑵the concentrations of NO and t-PA in the oxLDL group were significantly lower than those in the control group(P

Objective To determine the effects of curcumin microemulsion on proliferation and apoptosis of the human leukemia cell line K562 cells.Methods The curcumin microemulsion was prepared with the routine procedure.MTT assay was used to determine cell proliferation in cultured K562 cells,flow cytometry analysis was applied to examine cell apoptosis,and WT1 mRNA was determined with RT-PCR.The results about curcumin microemulsion were compared with these on curcumin.Results The prepared curcumin microemulsion was a stable clear solution with diameter of 10-100 nm.Curcumin microemulsion inhibited K562 cell proliferation by 24%,46%,68%with a 24 h incubation at dose of 2.5 μg/ml,5.0 μg/ml,and 10.0 μg/ml respectively,whereas curcumin reduced the proliferation by 6%,14%,25%at equal concentrations.WT1 mRNA level of curcumin microemulsion group(0.190±0.036)was reduced stronger than that of curcusin group(0.456±0.047).Conclusions Microemulsion is a great carrier for curcumin.Curcumin microemulsion is more effective in inhibiting proliferation,pro-apoptosis,and reducing WT1 gene expression than curcumin.A strong basis of medical value for the use of curcumin microemulsion to treat tumors is provided.

ObjectiveTo investigate the prevalence and distributing feature of atrial fibrillation (AF) in Xinjiang Kazaks adult population.MethodsFour-stage selected random samples aged 30-89 years from Tacheng,Yili and Aletai were analyzed.An epidemical study of AF was performed including inquiring medical history,recording electrocardiogram and auscultation. ResultsA total of 22 514 adults were surveyed.The prevalence of AF in Xinjiang Kazaks adult population was 0.37%,which was increasing with aging.The prevalence was higher in men than in women (0.5% vs 0.2%,P <0.01 ).In AF patients,23 was valvular AF.Ischemic stroke was the most frequent type and the stroke rate in the patients with AF was significantly higher than that without AF (6.0% vs 1.2%,P < 0.01 ).ConclusionsThe prevalence of AF in Xinjiang Kazaks adult population is lower than the reported national prevalence but patients with AF in this population would not like to take the necessary medicine. Therefore,the control of AF need to be reinforced.
