目的 探讨康力欣胶囊联合甘露聚糖肽治疗肝癌的临床疗效。方法 选取2014年2月-2015年7月在玉溪市人民医院肿瘤科接受治疗的肝癌患者86例,分成对照组(43例)和治疗组(43例)。所有患者均给予必要的化疗和碘油栓塞治疗,1次/周,连续治疗2周。对照组在此基础上静脉滴注甘露聚糖肽注射液,10 mg加入250 mL生理盐水,1次/d。治疗组在对照组基础上口服康力欣胶囊,3粒/次,3次/d。两组患者均连续治疗4周。观察两组的临床疗效,同时比较两组生存质量、免疫功能和血清基质金属蛋白酶水平改善情况。结果 治疗后,对照组客观缓解率(ORR)为41.86%,临床获益率(CBR)为74.42%;治疗组ORR为65.12%,CBR为90.70%,两组ORR、CBR比较差异具有统计学意义(P<0.05)。治疗后,对照组与治疗组患者生存质量改善率分别为74.42%和93.02%,两组差异比较具有统计学意义(P<0.05)。治疗后,两组CD³⁺、CD⁴⁺和CD⁴⁺/CD⁸⁺上升,差异有统计学意义(P<0.05);且治疗组变化的更显著(P<0.05)。治疗后,两组血清基质金属蛋白酶-2(MMP-2)和基质金属蛋白酶-9(MMP-9)水平均较同组治疗前明显降低(P<0.05);与对照组相比,治疗组降低的更显著(P<0.05)。结论 康力欣胶囊联合甘露聚糖肽治疗肝细胞癌具有很好的临床疗效,可以提高患者免疫能力及改善生活质量,具有一定的临床应用推广价值。

Epigallocatechin gallate (EGCG) is the main catechin in green tea. A large number of researches have revealed that green tea demonstrates a wide range of positive biological activities against serious chronic diseases, such as cardiovascular disease, neurodegenerative disorders, cancer, metabolic syndrome, and type 2 diabetes. These protective properties can be traced back to the potent antioxidant activities of EGCG. Recent studies have suggested that EGCG may exert its anti-oxidant effects by scavenging free radicals, metal chelation, inhibition of transcription factor activation, and adjusting the oxidation and anti-oxidant enzyme system, etc. This paper summarizes the research progress on anti-oxidative mechanism of EGCG, in order to provide reference for exploiting drugs with same or similar mechanism of EGCG for clinical application.
