In order to study the effects of pre-heating on the sensitivity of cells to tumor necrosis factor-α, the K562 cells were pre-heated at 40℃ for different times to induce heat shock protein 70(HSP70). To observe the effects of TNF-α concentration on the sensitivity of pre-heated cells, cells were pre-heated for 60 min and treated with TNF-α(50,100,200 and 400U/ml) for 16 hours, and the cells vitalities were detected by MTT.

为探讨预热对肿瘤细胞肿瘤坏死因子α敏感性的影响及其机理，将白血病患者胸腔渗出细胞系(K562细胞)在40℃预热不同时间(0、30、60、90、120、150和180min)，使细胞热应激蛋白70(HSP70)高表达；然后将预热60min细胞和未预热细胞分别暴露于50、100、200和400U/ml的TNF-α16小时，用MTT比色法检测细胞活力。

We also use rank sum test to analyse the differe- nce between the light pre-eclampsia group and the severe pre-eclampsia group (P=0.000),the early onset pre-eclampsia group and the late onset pre-eclampsia group (P=0.003). All of the results give the same conclude that the differences within the three groups are significant (P.05). Conclusion: We conclude that HLA-G proteins are normally expressed in invasive trophoblasts and HLA-G proteins expression is defective in most pre-eclamptic placenta.We propose that trophoblasts lacking HLA-G proteins are vulnerable to attack by the maternal immune system.

结论HLA-G分子特异性分布于胎盘EVCT的胞膜及胞浆中，生理妊娠组、子痫前期组间差异性存在表明其表达量的下降与子痫前期的发病相关；轻、重度子痫前期组间显著差异表明HLA-G分子表达量的下降与子痫前期病情严重程度相关，早发型重度子痫前期患者胎盘组织中HLA-G分子的表达明显低于迟发型组，提示我们HLA-G分子表达的降低程度还与发病早晚有关。

Based on a great deal of thesis, this survey takes current study result of education and pre-education fairness as the theoretical support and refers to the representative domestic research examples.
