HLA—DQA1等位基因与急性脑梗塞多种中医体质类型的相关性研究

对急性脑梗塞多种中医体质进行HLA-DQA1等位基因分型,分析体质类型的遗传易感性及体质与“证”和治疗的密切关系。采用PCR-SSP技术对观察组急性脑梗塞阴虚质、阳虚质、气虚质、痰湿质、血瘀质共103例及正常质对照组99例进行HLA-DQA1等位基因的基因分型。结果表明,HLA-DQA10501基因型在阴虚质明显高于正常质对照组(P＜0.01),HLA-DQA10301基因型在气虚质、痰湿质、血瘀质均明显高于正常质对照组(P＜0.01)。提示急性脑梗塞患者,HLA-DQA10501基因与阴虚质相关联;HLA-DQA10301基因与气虚质、痰湿质及血瘀质相关联;从分子生物学水平阐明了体质与“证”,体质与“同病异治”的遗传学背景。

Study on Correlativity of HLA-DQA1 Allelic Gene with Varied TCM Constitution Types of Acute Cerebral Infarction

Varied TCM constitutions in the patient of acute cerebral infarction were classifyed by using HLA - DQAl allehc gene to analyze hereditary susceptibility of constitution types and relation among constitution, syndrome and treatment. PCR-SSP technique was used for classification of Yin - deficiency Yang - deficiency, Qi - deficiency, phlegm - dampness and blood stasis constitution in 103 cases of acute cerebral infarction and HLA - DQAl allelic gene was used for gent classification in 99 cases of nomal constituion. Results indicated that HLA -DQA * 0501 gene type in Yin -deficiency constitution was significant higher than that of normal constitution CP<0. 01) : HLA -DQAl * 0301 gene type in Qi - deficiency, phlegm - dampness and blood stasis constitution all was higher than normal constitution (P <-0. 01). It is suggested that HLA - DQAl * 0501 gene is correlated with Yin - deficiency in the patient of acute cerebral infarction. Thus, genetical background of relation of constitution with syndrome, and constitution with " treating the same disease with different methods" are explained from view of point of molecular biology.
