生脉姜黄散对鼻咽癌放射抗拒株细胞移植瘤裸鼠肠道菌群的影响

Effects of Shengmai Jianghuang San on intestinal flora in nude mice with radio resistant cells of nasopharyngeal carcinoma

现代药理研究表明,生脉散具有增强免疫力、改善血液循环等功效;姜黄具有抗炎、抗癌、抗氧化等多种作用。生脉散联合姜黄在中药抗肿瘤的研究中是一种崭新的研究方向。目前鼻咽癌的主要治疗手段是放射治疗,但众所周知放射治疗会引起多种副作用,同时也会改变肠道菌群的构成。研究表明,鼻咽癌放疗后机体的病机主要为正虚血瘀,生脉姜黄散体现了中医益气活血养阴的重要治法。该研究用鼻咽癌抗照射细胞株对裸鼠种植移植瘤,然后利用16s rDNA测序平台对服用生脉姜黄散或照射治疗裸鼠的肠道粪便样本进行宏基因测序,之后对肠道菌群数据结果进行分析,探讨生脉姜黄散对肿瘤移植裸鼠肠道菌群结构产生的影响。结果表明,生脉姜黄散联合照射治疗可增强肿瘤治疗的疗效,放射治疗会降低裸鼠肠道菌群的总数与多样性,同时也会改变菌群结构组成。生脉姜黄散可保护菌落的多样性,也能部分恢复因照射引起的菌落失调。该研究为生脉姜黄散作为鼻咽癌放射治疗的增敏辅助用药提供了研究思路。

Modern pharmacological studies have shown that Shengmai San has the effects of enhancing immunity and improving blood circulation, and Curcumae Longae Rhizoma(Jianghuang) has anti-inflammatory, anti-cancer, anti-oxidation and other functions. Shengmai San combined with Jianghuang is a new research direction in the study of anti-tumor of traditional Chinese medicines. The main treatment for nasopharyngeal carcinoma is radiation therapy, but radiation therapy can cause a variety of side effects, and it also changes the composition of the intestinal flora. In this study, the 16 s rDNA sequencing platform was used to perform macro-sequence sequencing of the intestinal flora samples of nude mice bearing the veins of Shengmai Jianghuang San, and then the results of intestinal flora data were analyzed to investigate the effect of Shengmai Jianghuang San on tumors. The results showed that Shengmai Jianghuang San combined with irradiation could enhance the therapeutic effect of tumor treatment. Radiation therapy would reduce the total number and diversity of intestinal flora in nude mice, and also change the structure of the flora. Shengmai Jianghuang San could protect the diversity of colonies, and also partially restore the colony imbalance caused by irradiation. This study provides a research idea for Shengmai Jianghuang San as a sensitizing adjuvant for radiotherapy of nasopharyngeal carcinoma.
