Novel therapy for idiopathic pulmonary arterial hypertension： Can hepatocyte growth factor be beneficial？

Idiopathic pulmonary arterial hypertension （IPAH） is a progressive, nearly fatal condition that until recently has had very few treatment options. Median survival time for untreated IPAH was 2.8 years without effective drug intervention. IPAH is characterized by deregulated proliferation of pulmonary arterial endothelial and intimal smooth muscle cells resulting in progressive pulmonary vascular remodeling and an increase in pulmonary arterial pressure. In order to alleviate their symptoms, anticoagulants, diuretics, calcium channel blockers and inotropic agents have been used to treat patients with PAH. Moreover, specific targeted therapies using prostacyclins,

EGFR-TKI治疗后非小细胞肺癌中医证候研究

目的观察靶向药物治疗后非小细胞肺癌(NSCLC)患者的中医证候分布。方法采用临床流行病学调查方法观察506例表皮生长因子受体酪氨酸激酶阻滞剂(EGFR-TKI)治疗后的NSCLC患者症状、体征、舌脉四诊资料,运用聚类分析方法观察靶向药物治疗后NSCLC患者的中医证候特征规律,进行因子分析,观察各个证型辨证的主次症。结果患者中医证型主要为肺阴亏虚证(281例,55.53%)、气阴两虚证(145例,28.66%)、肺脾气虚证(80例,15.81%)。肺阴亏虚证主要证素为咳嗽、痰少、痰黏、皮疹瘙痒、皮肤干燥、口干渴、舌红、裂纹舌、脉细;次症为苔薄或苔白(P=0.001)。气阴两虚证主要证素为头晕、口干不欲饮、脉弱、少寐;次症为气促、干咳无痰、咽干、心烦(P=0.001)。肺脾气虚证主要证素为神疲乏力、恶心、纳差、大便不成形、舌淡红、苔腻、胖大齿痕舌、脉滑;次症为面萎黄或胸闷(P=0.001)。结论靶向药物治疗后NSCLC患者的证型主要为肺阴亏虚证、气阴两虚证和肺脾气虚证,其核心证型是肺阴亏虚证。
