PRDX6过表达增强肺癌细胞系A549的迁移和侵袭

目的探讨PRDX6过表达对肺癌细胞系A549迁移性及侵袭性的影响。方法 1)体外培养人肺癌细胞系A549,分为空白组、转染PRDX6组、转染空质粒组。2)Western blot检测细胞PRDX6蛋白表达;3)Transwell小室法检测细胞的迁移性及侵袭性。结果 1)转染PRDX6组PRDX6蛋白表达较空白组及转染空的质粒组明显增高(均P<0.05);2)转染PRDX6组迁移性及侵袭性较空白组及转染空质粒组显著增高(P<0.05)。结论 PRDX6的高表达增强肺癌细胞系A549的迁移性及侵袭性。

Jagged-1抑制小鼠胚胎干细胞分化为造血干/祖细胞

目的探讨Notch信号通路在小鼠胚胎干细胞(ESC)分化为造血干/祖细胞(HSC/HPC)中的作用。方法1)体外培养小鼠拟胚体细胞(EBs),使用Jagged-1蛋白活化Notch信号通路及DAPT(γ-分泌酶抑制剂)抑制Notch信号通路。实验分为拟胚体细胞复苏组(EB组)、对照组、Jagged-1组、DAPT组和Jagged-1-DAPT组。2)流式细胞计量术检测ESC特异性表型和HSC/HPC特异性表型的表达。3)实时定量PCR检测各组Notch信号通路基因、小鼠ESC表型基因和HSC/HPC表型基因的表达。结果1)Jagged-1组细胞胚胎干细胞数较对照组和Jagged-1-DAPT组明显增多(P<0.05),2)Jagged-1-DAPT组分化的HSC/HPC数较control组及Jagged-1组明显增多(P<0.05);3)Jagged-1组Notch1、Notch2、Notch4 mRNA表达量较对照组明显升高(P<0.05);4)DAPT组和Jagged-1-DAPT组中Notch1、Notch4 mRNA表达量较对照组降低(P<0.05)。结论Jagged-1激活Notch信号通路可抑制小鼠ESC向HSC/HPC的分化。

Policies on Chinese Medicine in China May Have Enlightenments to Complementary and Alternative Medicine in the World

From the event of TU You-you winning the Nobel Prize, this paper briefly reviewed the history of formation and development of policies on Chinese medicine （CM） in China. On the basis of analyzing the causes of policies on CM, it is believed that policies on CM in China may have 4 kinds of enlightenments to the development of complementary and alternative medicine （CAM） in the world. Forming the political advantages of policy-making by main leaders of the country attaching importance to CAM; implementing a diversified health care system policy for the goal of maximizing people＇s health interests; ensuring development of CAM by the coerciveness of law and the timeliness of policy adjustment; and promoting the protection and mining, sorting out and improving of CAM based on open and comprehensive policies.
