Abstract:
Objective To study the microRNA-related mechanism of acupuncture in promoting postoperative gastrointestinal motility of patients with colorectal cancer. Methods Thirty cases of postoperative gastrointestinal motility disorder patients with colorectal cancer were randomly divided into acupuncture group and control group, 15 cases in each group. The control group received conventional symptomatic and supportive therapy, and acupuncture group received acupuncture at bilateral foot triple points of Zusanli,Sanyinjiao,Taichong daily on postoperative day 1-5 on the basis of conventional therapy for the control group. Time for the first anal exsufflation and time for the first defecation after operation were observed for the evaluation of clinical efficacy. Meanwhile, miR-19a expression level in serum and miR-222 expression level in the cancer tissue were detected by polymerase chain reaction (PCR). Results (1)The total effective rate of acupuncture group was 80.0％,and that of the control group was 46.7％,the difference being significant (P<0.05). (2)Time for the first anal exsufflation and time for the first defecation after operation in acupuncture group were shorter than those in the control group, the difference being significant (P < 0.05). (3) Serum miR-19a expression level in acupuncture group was decreased obviously on postoperative day 5 compared to day 1 (P < 0.05), and the decrease in acupuncture group was superior to that in the control group (P<0.05). (4)The expression of miR-222 in the cancer tissue was positively relevant to time for postoperative first anal exsufflation in both groups (P<0.05),and the expression level in ineffective patients was higher than that in effective patients (P < 0.05). Conclusion Acupuncture can regulate serum miR-19a expression level and promote the recovery in postoperative gastrointestinal motility of patients with colorectal cancer. The recovery of postoperative gastrointestinal motility in patients with colorectal cancer and the acupuncture effect are affected by miR-222 expression in the cancer tissue.
