Résumé
Objective To investigate the effect of up-regulating miR-34c-5p on cloning formation and migration of nasopharyngeal carcinoma cell line HONE-1 in vitro. Methods Expression levels of miR-34c-5p in nasopharyngeal cell line NP69 and nasopharyngeal carcinoma cell line HONE-1 were investigated by real time quantitative PCR;Cloning Forma?tion Test and Transwell Migration Assay were used to explore the effect of up-regulating miR-34c-5p on proliferation and migration of nasopharyngeal carcinoma cell line HONE-1. Results The expression of miR-34c-5p in nasopharyngeal car?cinoma cell line HONE-1 was lower than that in normal nasopharyngeal cell line NP69. Up-regulating miR-34c-5p signifi?cantly suppressed the cloning formation and migration capacity, compared to those of NP69 cell line and HONE-1 with nor?mal level of miR-34c-5p(P<0.05). Conclusion Down-regulating miR-34c-5p involve in proliferation and migration of nasopharyngeal carcinoma and may be a used as a new therapeutic target for nasopharyngeal carcinoma.
Résumé
Objective To investigate the correlation between hepatitis B virus(HBV)markers and AFU,ALT,GGT.Methods 570 eases of HBV-infected people were divided into 4 groups according to the different performance modes.150 healthy people were considered as control group.rate method was used to detect AFU,ALT and GGT.Estimate the differences between the groups were compared.Results The comparison between the AFU,ALT,GGT in different performance mode of HBV and the control group showed:the differences of group 1,group 2 and group 3 were statistically significant(P＜0.01),the difference of group 4 was not significant(P＞0.01).The correlation between AFU,ALT,GGT of different performance mode showed:the changes of AFU and ALT,GGT in group 1,group 2 and group 3 were positively change-related.But the changes of AFU,ALT and GGT were not clearly related.The distribution of the rise of serum enzyme activity in different performance mode showed:the AFU,ALT and GGT rised in different proportion in group 1,group 2 and group 3.Conclusions The AFU,ALT and GGT activity of HBVinfected persons should be detected at the same time,and evaluate the damage of liver cells.This will do help to predict the progression of hepatitis.
