Objective:The relative expression of miR-4698 in liver cancer tissues and cell lines was detected, and its effect on the proliferation and migration of liver cancer cells and its molecular mechanism were analyzed.Methods:Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to analyze the relative expression of miR-4698 in liver cancer tissues and liver cancer cell lines. Among the lowest-expressing hepatocellular carcinoma cell lines, miR-4698 mimic and control mimic were transfected with liposome transfection method, and named as experimental group and control group. qRT-PCR was used to detect transfection efficiency. Cell counting kit-8 (CCK-8) and transwell migration experiments were used to detect the effects of overexpressing miR-4698 on the proliferation and migration ability of liver cancer cells. Bioinformatics and dual luciferase reporter gene experiments were used to predict and verify the binding of miR-4698 to target gene. qRT-PCR and Western blot were used to detect the relative expression of target gene at mRNA and protein levels, respectively.Results:Compared with the adjacent tissues, miR-4698 was significantly lower in the liver cancer ( P<0.01). Compared with normal hepatocytes, miR-4698 was significantly lower in hepatoma cell lines ( P<0.05), and the lowest in Huh7 cells ( P<0.01). After transfection, the expression of miR-4698 in Huh7 cells in experimental group was significantly increased compared with that in the control group ( P<0.01). Overexpression of the miR-4698 can inhibit the proliferation and migration of Huh7 cells ( P<0.05). Bioinformatics showed that the target gene of miR-4698 was polypeptide-n-acetylgalactosamine transferase 4 (GALNT4), and the double luciferase reporter gene confirmed that miR-4698 could bind to GALNT4 ( P<0.01). qRT-PCR showed that overexpression of miR-4698 could inhibit the expression of GALNT4 gene ( P<0.01). Western blot results showed that overexpression of miR-4698 decreased the protein expression of GALNT4, cyclin B and CDK1, and increased the protein expression of N-cadherin and ZEB-2. Conclusions:The expression of miR-4698 in liver cancer tissues and cell lines is significantly reduced. Overexpression of miR-4698 can inhibit the expression of GALNT4 gene and reduce the proliferation and migration ability of liver cancer Huh7 cells.

There were no obvious adverse reactions in both two groups, observation group had one light nausea,and control group had one light nausea and one case with alanine aminotransferase (ALT)slightly increased phenomenon,those patients were all back to normal on their own without treatment,the difference of adverse reaction rate between two groups was not significant. Conclusions Methotrexate and mifepristone has good efficacy and are safe and reliable in,treatment of ectopic pregnancy.

Background and purpose:Although cisplatin-based chemotherapies are used as the first-line treatment for ovarian cancers, the majority of patients eventually progress with platinum-resistant disease. miR-483-5p is overexpressed in lung cancer. However, the research on miR-483-5p in epithelial ovarian cancer (EOC) is still unclear. This study aimed to investigate the expression of miR-483-5p in EOC and its effects on cisplatin resistance in EOC cells.Methods:This study analyzed the expression of the miR-483-5p by real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) in EOC tissues, normal ovarian tissues, and EOC cells. The role of miR-483-5p in EOC was evaluatedin vitro by lentivirus-mediated knockdown of miR-483-5p or overexpression of miR-483-5p in EOC cell lines. Drug sensitivity assay was carried out by CCK-8 kit.Results:miR-483-5p was upregulated in EOC tissues as compared with normal tissues (P<0.01). Furthermore, miR-483-5p expression in advanced stage (Ⅲ–Ⅳ) EOC was significantly higher than that in early stage (Ⅰ–Ⅱ) EOC (P<0.05). Interestingly, miR-483-5p expression was higher in cisplatin-resistant A2780/CP cells than other cells. Increased miR-483-5p expression caused EOC cell resistance to cisplatin and downregulated the expression of p21 and Bcl-2, whereas reduced miR-483-5p expression induced its sensitivity and upregulated the expression of p21 and Bcl-2.Conclusion:The results suggest that miR-483-5p is highly expressed in EOC and contributes to cisplatin resistance. Thus, miR-483-5p is a potential therapeutic target for ovarian cancer.

The definition of rehabilitation should reflect the connotation and extension of rehabilitation medicine system,moreover,special attention should be paid to the process of translation,applications and promotion due to its derivation from Latin.The fourth edition of rehabilitation medicine textbook which published by People's Medical Publishing House described the definition of rehabilitation inaccurately,although integrated the foreign authority definitions.The definition of ‘ re-learning’has been described by the textbook without considering logical sequence,which caused difficulty in explaining and comprehending between teachers and students in class.Besides,application of another term of rehabilitation medicine in the textbook is imprudence.
