恶性肿瘤患者甲床紫晕与舌下络脉变化的对比观察

Comparative Observation on Changes Between Petechiae of Nail Matrix and Sublingual Collateral Branches (Luomai) in Malignant Tumor,

甲床紫晕指甲半月远侧甲床上的紫色晕带,宽约2mm以上。伴指压反应延迟者,多见于肺癌、肺转移癌、肝癌、全身转移癌等重症肿瘤及肺心病、支气管哮喘及慢性支气管炎等阻塞性肺疾患,辨证均属血瘀证。铸型标本显示甲床有三级血管弓,第一级弓发出直行血管,血流为瀑布样直流,不易瘀滞;第二级弓发出的微血管互相交叉吻合形成网眼,血流变缓,其弓正当甲半月远侧,在气滞血瘀微循环障碍时易形成甲床紫晕。通过与吉下络脉同步观察,认为两者均可作血瘀证体征。

Matrix peteciae of the nail a distal semilunar purplish zone 2 mm width, with retarded reaction to pressing, is mostly seen in lung cancer, metastatic cancer in the lungs, liver, cancer, general metastasis of carcinoma and obstructive lung diseases such as corpulmonale, bronchialasthma, chronic bronchitis. In TCM diagnosis, all cases belong to blood stasis syndrome, the animal model of which revealed three - grade vesselarches. From the first grade, blood vessels run straight out, and the blood stream flows like waterfall, uneasy to become static. Network with crossing capillaries stemmed out from the second grade in which the blood flows slowly. Its arch was just located at the distal semilunarnail materix, tending to form petechiae due to circulatory disturbancein blood stasis type. By synchronous observation on sublingualcollaterals, both can be seen as signs for the diagnosis of blood stasis syndrome.
