Methods The subjects were divided into two groups: PIH group (n= 15) and normotensive control group (n=15). Peripheral lymphocytes of the subjucts were separated by Ficoll-Hypaque density centrifugation. The lymphocytes were cultured in RPMI-1640 medium with or without pokeweed mitogen for ten days.Then the supernatant was collected and the IgG and IgM were measured by enzyme linked immunosorbent assay.

采用密度梯度离心法分离妊高征组(15例)和正常妊娠组(15例)的外周血B淋巴细胞，并在有或无美洲商陆有丝分裂原存在的情况下培养10天后，收集上清液，采用酶联免疫吸附试验测定每1×106个B淋巴细胞所分泌的IgG和IgM的量。

These results indicate that GDM can influence lipid and lipoprotein metabolism and lipid metabolism abnormalities can not be improved by diet restriction.Our data suggest that altered lipid profiles in women with GDM may result from unadapted proportion of carbohydrate and fat in the diet intake.We should monitor blood lipid and lipoprotein level while maintaining maternal blood glucose level.

GDM虽然病程短，仍然对血脂代谢存在一定影响，而且血糖控制后血脂并无改善，今后应注意对GDM患者限制碳水化合物的同时进行脂代谢的监测，合理调整饮食中脂肪含量可能将减少脂代谢异常，以减少GDM时妊高征的发生。

However the exact patho- physiological process of PIH still remains to be unrevealed so it is very important to study the etiology in order to prevent and cure PIH.
