头面部望诊积分与脑梗死患病率的相关性研究

目的探索头面部望诊在预测及诊断脑梗死中的价值。方法。。200例头面部望诊有异常的患者，根据其异常的轻重程度制定相应量化积分值，并行头颅磁共振成像（MRI）检查。发现有脑梗死者视为观察终点，记录为阳性。头颅MRI检查结果阴性者，追踪其6个月～18个月的病情变化和MRI检查结果，再次计算其量化积分值，进行统计分析，探讨不同积分值与脑梗死患病率的相关性，观察不同观察期脑梗死患病率的变化。结果积分阶梯I级～V级不同积分值与脑梗死患病率之间相关系数r=0．971，P=0．006，P〈0．01，二者显著正相关。随着望诊积分值的增加，脑梗死患病率显著增加。0～18个月不同观察期脑梗死例数与脑梗死患病率之间相关系数r=1．000，P=0．000，P〈0．001，二者显著正相关。随着时间的延长，脑梗死患病率显著增加。结论头面部望诊积分与脑梗死患病率呈显著正相关。

Correlation of Cerebral Infarction with the Scoring of Visual Inspection on the Head and Face Yin Jianming, Luo Luyi, Zhang Weibin, et al

Objective To explore the value of prediction and diagnosis of cerebral infarction by visual inspection of the head and face. Methods Two hundreds patients with abnormal finding by visual inspection of the head and face were selected. The value was quantified based the severity of abnormal findings. Examination of the head was performed by magnetic resonance imaging （MRI）. The cerebral infarction was the observation endpoint,and recorded as positive result. If MRI examination showed negative result, the patient will observed for 6 to 18 months and MRI examination was performed. The score will be revaluated for the purpose of statisti cal analysis. The relation between scoring, different observation period, and the cerebral infarction prevalence were discussed. Results The correlation coefficient,from scoring level I to V with the percentage of cerebral infarction prevalence,was r=0. 971 （P= 0. 006 ,P（0.01）. This was a significant positive correlation. With the increase of scoring in visual inspection, the cerebral infarction prevalence was increased obviously. At the 0 to 18 months of different observation period, the correlation coefficient of cerebral in farction cases was r=1. 000 （P=0. 000,P（0. 001）. This was also a significant positive correlation. With a longer time span, the cerebral infarction prevalence was increased significantly. Conclusion There was a significant positive correlation of the scoring by visual inspection on the head and face with the cerebral infarction prevalence.
