妊娠滑脉和病理滑脉的脉图和血液流变学对比研究

Comparative research on pulse graph and hemorheology of pregnant and pathological slippery pulse

目的:观察妊娠滑脉和病理滑脉脉图参数和血液流变学指标间的关系。方法:采用最适取法提取左关部脉图有关参数:升支最大斜率(MSAB)、降支最大斜率(MSBC)、降中波波幅(HFF’)、降中峡高/主波高(HE/HB)、主波宽(TW);同时检测血液流变学相关指标:全血比黏度之低切比黏度(ηb低切)、高切比黏度(ηb高切)、血浆比黏度(ηp)、红细胞聚集指数(Lb)、红细胞压积(Hct)。结果:两滑脉组MSAB、MSBC和HFF’较正常对照组增大,HE/HB和TW较正常对照组减小(P<0.001);与妊娠滑脉组比较,病理滑脉组MSAB、MS-BC和HFF’减低,而HE/HB和TW增大(P<0.01)。两滑脉组ηb低切、ηb高切、ηp、Lb和Hct较正常对照组均减低(P<0.001);与妊娠滑脉组比较,病理滑脉组ηb低切、ηb高切和ηp增高(P<0.01)。结论:妊娠滑脉组血液黏滞性较病理滑脉组低。

Objective： To observe the relations between the parameters of pulse graph of pregnant and pathological slippery pulse and the indexes of hemorbeology. Methods： The pusle diagram parameters （ MSAB, MSBC, HFF＇, HE/HB and TW） of left guan pulse were extracted by the best extraction method, and the indexes of hemorbeology（low shear ηb, high shear ηb, ηp, Lb and Hct） were tested. Results： Compared with the control group , MSBC and HFF＇of the two slippery pulse groups increased, but HE/HB and TW decreased significantly（ P 〈 0.01 ）. Compared with the pregnant slippery pulse group , M SBC and HFF＇ of pathological slippery pulse group reduced, but HE/HB and T W increased obviously（ P 〈 0.01 ）. ηb of low shear, ηb of high shear, ηp, Lb and Hct of the two groups became lower than those of control group （ P 〈 0.01 ）. ηb of low shear, ηb high of shear and ηp of pathological slippery pulse group increased compared with pregnant slippery pulse group sibnificantly（ P 〈 0.01 ）. Conclusion： Blood viscosity is lower in pregnant slippery pulse group than in pathological slippery pulse group.
