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(η)p)、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、MSBC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,病理滑脉组曲低切、加高切和仰增高(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.
