抗凝血酶Ⅲ、蛋白C、蛋白S活性与脑梗死的相关性研究

Relation between antithrombin Ⅲ,protein C,protein S with cerebral infarction

目的研究血浆抗凝血酶Ⅲ(AT-Ⅲ)、蛋白C(PC)和蛋白S(PS)活性动态变化与脑梗死发病的关系。方法对126例脑梗死患者按年龄、发病时间和梗死范围分组,同时选择健康体检30例作为健康对照组,检测血浆中AT-Ⅲ、PC和PS的活性,并分析其活性变化与脑梗死年龄、发病时间及梗死范围之间的关系。结果急性期青年组的AT-Ⅲ、PC、PS活性低于急性期中老年组、差异有统计学意义(P<0.05);急性期AT-Ⅲ、PC、PS活性低于恢复期和对照组,差异有统计学意义(P<0.05);恢复期AT-Ⅲ和PS活性低于对照组,差异有统计学意义(P<0.05),而恢复期PC活性与对照组比较,差异无统计学意义(P>0.05);进一步研究发现,AT-Ⅲ、PC、PS活性在小梗死组、中梗死组、大梗死组间呈逐渐降低的趋势,差异均有统计学意义(P<0.05)。结论AT-Ⅲ、PC、PS活性降低是脑梗死发生的重要因素,特别与45岁以下青年人脑梗死的发生密切相关。观察其活性变化对判断脑梗死病情的发展有重要的临床意义。

Objective To study the relation between the levels of protein C（PC）,protein S（PS）,antithrombin Ⅲ（AT-Ⅲ）with cerebral infarction.Methods 126 patients with cerebral infarction were divided into the groups according to the age,onset time and infarction area and contemporaneous 30 individuals with healthy physical examination were selected as the control group.The levels of PC,PS and AT-Ⅲ were detected.The relation between the change of these indicator levels with the age,onset time and infarction area was analyzed Results The levels of AT-Ⅲ,PC and PS in the acute stage youth group were lower than those in the acute stage middle age and elderly group with statistical differences between them （P ＆lt;0.05）.The level of the AT-Ⅲ,PC and PS in the acute stage group were lower than those in the recovery stage group and the control group,difference had statistical significance（P ＆lt;0.05）.The levels of AT-Ⅲ and PS in the recovery stage group were lower than those in the control group with statistical difference （P ＆lt;0.05）,but the level of PC had no statistical difference between the recovery stage group and the control group.The further study found that the level of AT-Ⅲ,PC and PS in the small infarction group,middle infarction group and large infarction group showed the gradually decreasing trend,the differences had statistical significance （P ＆lt;0.05）.Conclusion The decrease of AT-Ⅲ, PC and PS levels is the importan factor of cerebral infarction occurrence and is closely correlated with cerebral infarction ocurrence especially in the patients less than 45 years old.Observing the change of PC,PS and AT-Ⅲ levels has the important significance for judging the cerebral infarction progression.
