MicroRNA-26b-5p regulates cell proliferation, invasion and metastasis in human intrahepatic cholangiocarcinoma by targeting S100A7.

The present study aimed to investigate the effects of microRNA expression in intrahepatic cholangiocarcinoma (ICC). It was identified that the expression of microRNA-26b-5p (miR-26b-5p) was downregulated in ICC tissues compared with matched adjacent non-tumor tissues. Furthermore, miR-26b-5p expression was downregulated in metastatic ICC tumor tissues and invasive ICC cell line subpopulations compared with non-metastatic tumor tissue and the parental ICC cells. In vitro studies demonstrated that transfection with an miR-26b-5p mimic inhibited the proliferation, migration and invasion of RBE and HCCC-9810 cells, whereas an miR-26b-5p inhibitor promoted these abilities. S100 calcium-binding protein A7 (S100A7) was predicted as a direct target of miR-26b-5p. Transfection with an miR-26b-5p mimic decreased S100A7 expression, whereas an miR-26b-5p inhibitor increased S100A7 expression. The result of a dual luciferase reporter assay also indicated this interaction. S100A7 was therefore confirmed as a direct target of miR-26b-5p in ICC. The knockdown of S100A7 abrogated the effect of miR-26b-5p on cell migration in RBE and HCCC-9810 cells. In conclusion, the present study demonstrated that miR-26b-5p suppresses the proliferation, migration and invasion of ICC cells by suppressing S100A7.

[Effects of compound Centella asiatica enema on kidneys coefficient, electrolytes and blood in chronic renal failure rats].

OBJECTIVE: To study the pharmacological effects of compound Centella asiatica enema on chronic renal failure (CRF) rats. METHODS: Rats were divided into control group, CRF model group, Niaoduqing positive control group, compound Centella asiatica enema high, middle and low three groups kidney coefficient, electrolyte levels, hematocrit (HCT), red blood cell counts (RBC), hemoglobin (HGB) content were observed after 30 days's treatment. RESULTS: Compared with the model group, the level of the electrolyte, HCT, RBC, HGB of rats in compound Centella asiatica enema high-doses group and the Niaoduqing group were significantly improved. CONCLUSION: High-doses of compound Centella asiatica enema has significant therapeutic effect on CRF rats.
