Department of唧hthalmology,the Second A.f ̄liated Hospital of Chongqing Medical University,Chongqing China,400010 [Abstract]0bjeetJve To explore the mechanism of quercetin, inhibiting on sear formation following slaueoma filtration surgery, and provided theory bases for clinical results.Methods Fifry—f0ur eyes of rabbits received standard trabeculectomy.The rabbits’eyes had been divided into three groups.Group A received blank oph— thalmie gel twice per day after operation;group B received quercetin ophthalmic gel twice per day after operation;group C re— ceived no special treatments.Clinical observations were performed by naked eyes and slit-lamp microscope every day.Meanwhile score of bleb Was recorded.Histopathologie changes in filter bleb were investigated at week 1,2,4 after operation.Results There Was no serious complication in each group.The group B’S scores of bleb were the highest.In group A,the filtrating pathway Was almost blocked with the newly generated collagen,Masson staining showed the collagen density Was high;and the immunohistochemieal staining showed significantly positive expressions of TGF一131 and TGF-[3R1. Comparied with group A,the opening time of filtrating pathway of group B was longer and collagen Was sparse; Masson Staining showed the collagen density of group B Was lower than that of group A at diferent time points.There Was weekly positive expres— sion of TGF-[31 and TGF—I3R1(P<0.O1).The situation in group C Was similar to group A.Conclusion Quereetin can inhibit the for— mation of the bleb searing after filtration surgery;one of the mech— anisms is decreasing the expression of TGF一13 1 and TGF—BR1.

[摘要] 目的 比较不同脂质体槲皮素对人食管癌Eta109和Eta9706细胞增殖的作用,并初步探讨其作用 机制。方法采用旋转蒸发法制备氯仿和甲醇溶解类脂物质的脂质体槲皮素LQ 和按同比例的氯仿和DMSO作 为溶剂的脂质体槲皮素LQ ,用DMSO直接溶解槲皮素制备非脂质体槲皮素nLQ,分别作用于Eeal09和Eea9706 细胞(分别作为LQ。、LQ:及nLQ组),同时设立对照组。M1Tr实验检测各组细胞抑制率,免疫组织化学染色和免疫 印迹法检测磷酸酶基因(PTEN)和细胞周期素Dl(Cyclin DI)蛋白表达。结果各组细胞增殖的抑制效应、上调 PTEN和下调Cychn D1蛋白表达的效应呈现同一趋势,即LQ 组>LQ。组>nLQ组>对照组,尸<0.05。结论 脂质体槲皮素对食管癌细胞增殖有抑制作用,LQ:的抑制率高于LQ ;上调PTEN表达、下调Cyclin D1表达可能为 其作用机制之一。 [关键词]磷酸酶基因;细胞周期素D1;脂质体槲皮素;Eca-109细胞系;Eca-9706细胞系 [中图分类号] R735.1 [文献标识码] A [文章编号] 1002-266X(2009)07-0019-04
Effects of liposomal quercetin on the proliferation and expression of human
esophageal cancer cells PEI Ying-xin,WANG Sha—sha。GAO Han—chang (College ofPublic Health,Zhengzhou Unive ̄ity,Zhengzhou 450001,P.R.China) Abstract:Objective To explore the efects and mechanisms of diferent liposomal quercefins(LQ)on the prolifera— tion of human esophageal cancer Eca1 09/9706 cells.Methods Two kinds of liposomal quercetins,Chloroform+Methanol (LQ1)and Chloroform+DMSO(LQ2)used as respective solvents were prepared through rotary evaporation and repeated lyophilizing-thawing.The cultured human esophageal cancer Eca一109/9706 cells were divided into 4 groups,tlu ̄e experi・ mental groups were treated with LQl,LQ2,non・liposomal quercefin(nLQ)respectively and control group(C)treated with no drag.MIT assay Was used to detect the suppressing rate(SR)of the cell survival,the immunohistochcmistry Was used to examine the expression of PTEN and Cyclin D1.Results Compared with the control group,the SR of the cell survival Was enhanced,the expression of PTEN Was up—regulated and the expression of Cyclin DI Was down・regulated in the expcri- mental groups.The above effects in the LQ2 group>LQ1 group>nLQ group,P<0.05.Conclusion Liposomal quereetin can inhibit the proliferation of human esophageal cancer Eca109/9706 cells,and the effect of LQ2 is more notable.31fis may be associated with the up—regulation of mN and down—regulation of Cyclin DI.
