骨髓增生异常综合征中医证型与遗传学及预后的相关性研究

目的:探讨骨髓增生异常综合征(MDS)患者中医证型与分子生物学、细胞遗传学及预后的相关性。方法:采用非参数秩和检验或卡方检验的统计学方法,回顾性分析85例初诊MDS患者的中医证型、外周血指标、疾病分型、分子生物学情况、细胞遗传学情况、预后情况,并探讨中医证型与其后几项之间的相关性。结果:85例MDS患者的中医证型以气阴两虚、毒瘀阻滞证为主,其次为脾肾两虚、毒瘀阻滞证和邪热炽盛、毒瘀阻滞证。邪热炽盛、毒瘀阻滞证患者的中性粒细胞绝对值(ANC)水平显著低于脾肾两虚、毒瘀阻滞证患者(P<0.01),气阴两虚、毒瘀阻滞证患者的血红蛋白(HGB)水平显著低于脾肾两虚、毒瘀阻滞证患者(P<0.001)。3组证型间疾病分型分布比较,差异有统计学意义(P<0.05);邪热炽盛、毒瘀阻滞证患者的疾病分型全为原始细胞增多型(EB型)。3组证型间转录调节因子1(ASXL1)基因突变率、染色质重塑和转录调控基因功能组突变率、3种预后系统积分比较,差异有统计学意义(P<0.05),邪热炽盛、毒瘀阻滞证组转录调控基因功能组突变率和3种预后系统积分均高于其他两组(P<0.05)。在3个预后积分系统的较高危组中,邪热炽盛、毒瘀阻滞证患者占比均高于其他两种证型。结论:MDS病机以虚为本,临床患者以虚实夹杂证多见;邪热炽盛、毒瘀阻滞证预后较差,推测其机制可能与ASXL1基因突变、7号染色体的完全丢失和其长臂的部分缺失(-7/7q-)等遗传学情况相关。

从中医病机探析肺癌肿瘤微环境

肺癌是当今世界发病率和死亡率一直居高不下的恶性肿瘤,严重威胁着人民的生命健康。现代医学对肺癌的治疗基本经历了3场变革——传统的放化疗、精准靶向治疗、免疫治疗。其中免疫治疗主要通过适应性免疫系统来监视并杀伤肿瘤细胞,当下热门的嵌合抗原受体T细胞免疫疗法正是通过增强T细胞靶向杀伤肿瘤细胞的能力,达到抗癌的目的。而免疫细胞是肿瘤微环境(TME)的一部分,可见,干预TME已然成为攻克癌症的着眼点。根据中医取类比象思维推测肺癌TME,并将其病机归纳为:免疫逃逸类似营卫失和、肺卫不固;缺氧微环境类似肺脾肾气虚;酸性微环境类似痰湿阻肺;炎性微环境类似痰瘀癌毒积聚。提示以肺癌TME与中医病机契合点为指导,为中医药治疗肺癌提供遣方用药的参考依据。
