Competing endogenous RNAs (ceRNAs) transcripts can communicate with microRNAs (miRNAs) through competitively binding the common miRNA response elements (MREs),which remove or decrease the repression of target genes of miRNAs.The present studies indicate that a large amount of genes,serving as ceRNAs,can promote or inhibit the occurrence of liver cancer by competing the binding site of same genes that can promote or suppress tumorigenesis.

Objectives To observe the effect of Jianpi-Huayu decoction for preventing the patients from the recurrence of colonic adenoma after endoscopic mucosal resection. Methods A total of 60 patients with colonic adenoma who received endoscopic mucosal resection were divided randomly into the experimental group (taking Jianpi-Huayu decoction) and the controlled group (taking nothing as treatment), 30 patients in each group. Both groups were treated for 1 year. After 1 year, colonscopy was taken, and the number and size of colonic adenoma were recorded. The expression of COX-2, Ki67 in the colonic mucosa were detected the immunohistochemistry, and the negative rate of COX-2, Ki67 were also detected. Results After the treatment, the number (0.20 ± 0.48 vs. 1.67 ± 1.54, t=4.980) and size (0.23 ± 0.57 vs. 2.73 ± 2.80, t=4.788) of colonic adenoma in the experimental group were statistically lower than those in the ontrolled group (P<0.01);the expression of COX-2 (1.96 ± 1.27 vs. 3.64 ± 1.95, t=3.673) and Ki67 (2.04 ± 1.46 vs. 4.50 ± 1.73, t=5.558) in the the experimental group were statistically lower than those in the ontrolled group (P<0.01). The number of the paitents whose COX-2, Ki67 negative rates in the experimental group were 21 and 22, and the control group were 12(P=0.004) and 14 (P<0.001), which showed the significant difference between two groups. Conclusions The Jianpi-Huayu decoction could reduce recurrence of colonic adenoma after endoscopic mucosal resection, the mechanism was decreasing the expression of COX-2, Ki67 in colonic mucosa.

Objective To investigate the protective effects of daidzein (DD) on myocardial hypertrophy and fibrosis induced by pressure overload in rats and to study its mechanism. MethodsMyocardial hypertrophy and fibrosis model of rats induced by pressure overload was prepared by constricting abdominal aorta. The operated rats were randomly divided into sham operated control group, aorta-constricted model group, and three DD groups (30, 60, and 120 mg/kg). Four weeks later, the heart-weight (HW), left ventricular weight (LVW), the ratio of HW/BW and LVW/BW (LVI), and the cardio-myocyte diameters (MD) after dying by HE color were measured. The content of collagen and nitric oxide (NO), the activity of calcineurin (CaN) and Na+, K+-ATPase, Ca2+-ATPase in the left ventricle were quantified with spectrophotometry. The angiotension Ⅱ (AngⅡ) in the left ventricle was messured with radioimmunoassay. Results In aorta-constricted model group, the ratio of HW/BW, LVI, and MD as well as the content of collagen and AngⅡ, the activity of CaN in the left ventricle was significantly increased, and Na+, K+-ATPase, Ca2+-ATPase activity and NO content in the left ventricle were obviously decreased. After treatment of the left ventricular with DD, NO content, Na+, K+-ATPase, Ca2+-ATPase activity were significantly increased, the content of collagen and of AngⅡ and the activity of CaN in the left ventricle and the ratio of HW/BW, LVI, and MD were significantly reduced. ConclusionDD has protective effects on ventricular remodeling in rats with myocardial hypertrophy and fibrosis induced by pressure overload and its mechanism may be related to raising NO content and reducing the level of AngⅡ and the activity of CaN.
