目的考察槲皮素、虎杖苷、染料木素的抗氧化能力及对中波紫外线( UVB)致永生化人角质形成细胞( HaCaT )损伤的保护作用。方法以维生素C为阳性对照药,通过DPPH自由基清除实验,羟基(· OH)自由基清除实验,测定槲皮素、虎杖苷、染料木素不同浓度的抗氧化能力。体外培养HaCaT细胞,与槲皮素、虎杖苷、染料木素100μmol/L共抚育30 mim后,以30 mJ/cm2 UVB直接照射细胞,12 h后收集细胞, MTT法检测细胞增殖活性,ELISA法和硫代巴比妥酸( TBA)法分别检测TNF-α、MDA含量,黄嘌呤氧化酶法测定超氧化物歧化酶( SOD)活性。结果槲皮素、虎杖苷、染料木素对DPPH和· OH自由基都具有一定的清除力,其清除能力的大小为染料木素<虎杖苷<槲皮素。 UVB辐射对HaCaT细胞造成明显损伤,三种药物作用于HaCaT细胞,与单纯UVB辐射对照组相比,经UVB辐射后各给药组的细胞活性明显增高( P<0.05),TNF-α分泌减少(P<0.05),MDA含量降低(P<0.05),SOD活力增强(P<0.05)。结论三种药物能抑制UVB辐射诱导的HaCaT细胞损伤,促进细胞存活增殖,对UVB辐射损伤的HaCaT细胞具有保护作用,其清除体内自由基,增强细胞的抗氧化能力可能是这些药物抑制UVB辐射诱导HaCaT细胞损伤的作用机制之一。

Objective To investigate the antioxygenation and protective effect of quercetin polydatin and genistein on HaCaT cells injured by UVB irradiation .Methods The antioxygenation of quercetin polydatin and genistein compared on the base of the elimination tests of DPPH free radical and hydreoxide ( · OH) free radical with vitamin C as positive control ,and HaCaT cells were incubated in the medium supplemented with quercetin polydatin and genistein 100 μmol/L for 30 min before irradiating HaCaT cells with UVB(30 mJ/cm2).Irradiated by UVB for 12 h,the cells were collected ,and the viability of cell proliferation was detected by MTT method .The level of TNF-αwas detected by ELISA method, the content of MDA and the activity of SOD were detected by reagent kit. Results Both of them above could scavenge DPPH and · OH free radical.The scavenging ability was genistein <polydatin<quercetin.UVB irradiation caused significant damage to HaCaT cells .However,when the three drugs acted on HaCaT cells ,compared with those treated by UVB irradiation only, the viability and the activity of SOD of HaCaT cells increased(P<0.05),accompanied by a decrease of TNF-αand MDA level(P<0.05).Conclusion Those three drugs can inhibit UVB irradiation-induced HaCaT cells damage ,promote cell survival proliferation ,and have a protection effect on HaCaT cells injured by UVB irradiation .Maybe one of mechanisms related to its inhibition to the damage effect of UVB irradiation on HaCaT cells is clearing free radicals and enhancing the antioxidant capacity of cells.
