健脾养胃方联合新辅助化疗对胃癌患者临床疗效的影响及机制研究

Study on Clinical Efficacy and Mechanism of Jianpi Yangwei Formula Combined with Neoadjuvant Chemotherapy for Patients with Gastric Cancer

目的观察健脾养胃方配合新辅助化疗对胃癌患者临床疗效的影响及机制研究。方法按照随机数字表法将56例胃癌患者随机分为对照组(29例)和治疗组(27例)。对照组给予以奥沙利铂和替吉奥为主的SOX术前新辅助化疗方案,治疗组在新辅助化疗基础上配合健脾养胃方治疗。观察2组患者术前辅助化疗疗效(TRG分级)、中医证候积分的变化;免疫组化检测胃癌组织中叉头状转录因子P3(FoxP3)、T细胞免疫球蛋白黏蛋白分子3(Tim3)蛋白的表达;实时定量PCR检测胃癌组织白细胞介素-10(IL-10)、白细胞介素-2(IL-2)、白细胞介素-8(IL-8)、肿瘤坏死因子-α(TNF-α)mRNA的水平。结果治疗后,与对照组相比,治疗组TRG分级评分降低(P<0.05);治疗组中医证候积分显著低于治疗前(P<0.05~0.01),且低于对照组(P<0.05);与对照组相比,治疗组胃癌组织Tim3、FoxP3蛋白水平降低(P<0.05),IL-8、IL-10 mRNA水平降低(P<0.05)。结论健脾养胃方配合新辅助化疗方案,可有效提高胃癌新辅助化疗的临床疗效,机制可能与该方调节患者肿瘤微环境中Tim3、FoxP3及IL-8、IL-10有关。

OBJECTIVE To observe the clinical efficacy and mechanism of Jianpi Yangwei Formula combined with neoadjuvant chemotherapy(NACT)on patients with gastric cancer.METHODS According to the random number table method,56 patients with gastric cancer were randomly divided into the control group(29 cases)and the treatment group(27 cases).The control group was given preoperative NACT consisting of oxaliplatin and tegafur-gimeracil-oteracil potassium capsule,and the treatment group was treated with Jianpi Yangwei formula besides NACT.The tumor regression grade(TRG)and TCM syndrome scores were observed in the two groups.The expressions of forkhead box protein 3(FoxP3)and T cell immunoglobulin domain and mucin domain 3(Tim3)protein in gastric cancer tissues were detected with immunohistochemistry.Real-time PCR was applied to detect the levels of interleukin-10(IL-10),interleukin-2(IL-2),interleukin-8(IL-8),and tumor necrosis factor-α(TNF-α).RESULTS After treatment,the TRG score of the treatment group was lower than that of the control group(P<0.05).The TCM syndrome score in the treatment group was decreased significantly after treatment(P<0.05,P<0.01),and less than that in the control group(P<0.05).Compared with the control group,the protein expressions of Tim3 and FoxP3 in gastric cancer tissue of the treatment group decreased(P<0.05),and the levels of IL-8 and IL-10 also decreased(P<0.05).CONCLUSION Jianpi Yangwei formula combined with neoadjuvant chemotherapy can effectively improve the clinical efficacy of NACT for gastric cancer.The mechanism may be related to the regulation of Tim3,FoxP3 and IL-8,IL-10 in the tumor microenvironment.
