急性脑梗死患者血浆同型半胱氨酸水平及其干预治疗探讨

目的 探讨急性脑梗死患者给予维生素B_(12)制剂(甲钴胺)和叶酸(Fa)治疗前后血浆同型半胱氨酸(Hcy)、叶酸和维生素B_(12)水平变化及其对预后的影响.方法 检测152例急性脑梗死患者和132例正常人血浆同型半胱氨酸(Hcy)、叶酸、维生素B_(12)水平,并对急性脑梗死患者进行神经功能缺损评分(NIHSS);将急性脑梗死组随机分为干预组和非干预组,干预组给予维生素B_(12)制剂(甲钻胺)联合叶酸治疗,治疗4周后复测血浆同型半胱氨酸(Hcy)、叶酸和维生素B_(12)水平,并再次进行神经功能缺损评分(NIHSS).结果 急性脑梗死组和正常健康对照组之间血浆Hcy水平、叶酸和维生素B_(12)水平存在明显差异(P<0.01),予以补充叶酸和维生素B_(12)(甲钴胺)治疗后,干预组血浆Hcy水平明显下降,神经功能缺损评分显著升高,与非干预组相比有显著性差异(P<0.05).结论 急性脑梗死患者血浆Hcy水平升高,补充叶酸、维生素B_(12)制剂有助于降低血浆Hcy水平,有利于脑梗死疾病的转归.

Abstract：

Objective To explore the changes of the levels of plasma homocysteine ( Hcy), folate and vitamin B_(12) and the relationship between the changes and the prognosis in patients with acute cerebral infarction who were treated with vitamin B_(12) preparation (methylcobalamin) and folate. Methods The plasma level of Hcy, folate and vitamin B_(12) ( VitB_(12)) of 152 patients with cerebral infarction and 132 healthy people were measured, and the patients with acute cerebral infarction were given a mark with the evaluation of neurological impairments (NIHSS). The patients with acute cerebral infarction were randomly divided into intervention group and non-intervention group. The intervention group was treated with vitamin B_(12) preparations (methylcobalamin) and folate. After 4 weeks, retested the plasma homocysteine (Hcy), folate and vitamin B_(12) levels, and carried out NIHSS score once again. Results In the plasma level of Hcy, folate and vitamin B_(12), there were significant differences between the acute cerebral infarction group and the healthy control group (P < 0.01 ). In intervention group, the plasma homocysteine levels decreased significantly, and the evaluation scores increased significantly after intervention treatment, and there was significant differences between intervention group and non-intervention group (P <0.05). Conclusion The levels of plasma Hcy increased in the patients with acute cerebral infarction. Being added with folate and vitamin B_(12) preparations was well to reduce the levels of plasma Hcy, and it was also conducived to the prognosis of acute cerebral infarction.
