BACKGROUND:Among the factors causing vascular endothelial cell injury,angiotensin Ⅱ(Ang Ⅱ) caused by renin-angiotensin system (RAS), especially by local RAS, plays an important patho-physiological role.OBJECTIVE: To observe the effect of tanshinone ⅡA on the vascular endothelial cells secreting nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) gene expression as well as intracellular Ca2+ level induced by Ang Ⅱ, and investigate the protective effect of tanshinone ⅡA on vascular endothelial cells.DESIGN: Controlled observation experiment.SETTING: Department of Emergency, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: This experiment was carried out in the Experimental Center for Basic Medicine, Tongji Medical College,Huazhong University of Science and Technology from March 2006 to October 2006. Porcine aorta used in this experiment was provided by the Department of Pathophysiology of Tongji Medical College.METHODS: Nitric acid deoxidization method and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the effects of Ang Ⅱ of different concentrations (10-8 to 10-6 mol/L) on endothelial cells secreting NO and eNOS mRNA expression in cultured porcine aortic endothelial cells at different time points (1,6 and 24 hours) separately, then 50 mg/L tanshinone Ⅱ A was respectively added at different time point (0, 6 hours) when Ang Ⅱ was at 10-6 mol/L, and changes in NO production and eNOS gene expression were detected respectively at 1, 6 and 24 hours. Intracellular Ca2+ level was also detected with laser scanning confocal microscopy.MAIN OUTCOME MEASURES: ① NO content. ②eNOS mRNA expression. ③Intracellular Ca2+ level.RESULTS: ① NO production and eNOS mRNA expression were decreased with increase of Ang Ⅱ concentration and prolongation of time (P < 0.01). ② NO production and eNOS mRNA expression in each tanshinone ⅡA-treated group were significantly higher than those in the Ang Ⅱ group. At 1 and 6 hours of tanshinone ⅡA treatment, production of NO and eNOS mRNA expression in the Ang Ⅱ + tanshinone ⅡA group were significantly higher than those in the Ang Ⅱ 6 hours + tanshinone ⅡA group (P < 0.05); There were no significant differences in NO production and eNOS mRNA expression between two groups at 24 hours (P > 0.05). ③Intracellular Ca2+ level in the Ang Ⅱ group was significantly higher than that of control group (P < 0.01), and intracellular Ca2+ level in the tanshinone ⅡA + Ang Ⅱ was significantly lower than that in the Ang Ⅱ group (P < 0.05).CONCLUSION: Tanshinone Ⅱ A has a protective effect on vascular endothelial cells and their functions by suppressing the inhibition of Ang Ⅱ on NO level and eNOS gene expression in cultured porcine aortic endothelial cells.

Objective To study the MTHFR gene (677 gene loci and 1298 gene loci) mutations in Chinese patients with keloid. Methods The tissue DNA was extracted from 20 samples of keloids. and peripheral blood samples from the same patients were employed as the control. Polymerase chain reaction(PCR) was used to amplify the Mthfr 677 gene loci and Mthfr 1298 gene loci from the keloid tissue DNA and peripheral blood DNA. and the PCR products were sequenced directly and then compared with the GenBank data. Results Mutations were detected in 17 out of 20 keloids on Mthfr 677 gene loci, the mutation incidence was 85.0 %. Mutations were detected in 13 out of 20 keloids on Mthfr 1298 gene loci, and the mutation incidence was 65.0 %. The mutation involved point mutation, deletion and insetion as well as multisite and multitype. No MTHFR gene mutation was detected in all peripheral blood samples . Conclusion There is a strong correlation between the MTHFR gene (677 gene loci and 1298 gene loci) mutation and keloid.
