目的:探讨补肾健脾活血方对过表达分泌型卷曲相关蛋白1(secreted frizzled related protein 1,SFRP1)、沉默SFRP1的UMR106细胞成骨分化及雌激素受体α(estrogen receptorα,ERα)的影响。方法:通过构建SFRP1过表达及沉默重组腺病毒载体...目的:探讨补肾健脾活血方对过表达分泌型卷曲相关蛋白1(secreted frizzled related protein 1,SFRP1)、沉默SFRP1的UMR106细胞成骨分化及雌激素受体α(estrogen receptorα,ERα)的影响。方法:通过构建SFRP1过表达及沉默重组腺病毒载体,并转染大鼠类成骨细胞系UMR106细胞,初步分为空载腺病毒组、过表达SFRP1组、沉默SFRP1组,并根据含药血清和生理盐水(空白)血清干预的不同分为6组,观察6组细胞的碱性磷酸酶(alkaline phosphatase,ALP)活性及细胞ERα蛋白表达情况。结果:含药血清干预的空载腺病毒组、SFRP1沉默组及SFRP1过表达组72 h后UMR106细胞ALP活性和ERα蛋白表达均高于空白血清干预的空载腺病毒组、SFRP1沉默组及SFRP1过表达组(P<0.05);空白血清+SFRP1沉默组的UMR106细胞ALP活性及ERα蛋白表达高于空白血清+空载腺病毒组(P<0.05),而空白血清+SFRP1过表达组的UMR106细胞ALP活性及ERα蛋白表达低于空白血清+空载腺病毒组(P<0.05)。结论:过表达SFRP1可以抑制UMR106细胞成骨分化,并下调ERα蛋白表达;沉默SFRP1和补肾健脾活血方均可促进UMR106细胞成骨分化,并上调ERα蛋白表达,且两者共同干预时作用更显著,说明补肾健脾活血方能够抑制SFRP1表达,而SFRP1并不是补肾健脾活血方调节成骨细胞代谢,提高成骨分化活性和促进ERα蛋白表达的唯一靶点,可能存在其他靶点共同促进调节成骨细胞代谢。展开更多

Levels of serous creatinine (SCr), blood urea nitrogen (BUN), blood albumin (Alb), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and hemoglobin (Hb) were checked every two months and the rate of progression of CRF was estimated by slope of the creatinine reciprocal (1/SCr) with time (months).Results: Levels of SCr and BUn in group B were lower and HDL higher than those in group A significantly,P < 0.05. Mean slopes of the creatinine reciprocal with time in the two groups were markedly different,P < 0.01.Conclusion: Additional CD treatment based upon the low protein diet and controlling blood pressure could retard the rate of progression of CRF evidently.展开更多
