ABSTRACT
Objective To explore the expression and clinical significance of miR-150-5P in patients with hepatocellular carcinoma (HCC).Methods Expressions of miR-150-5P were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) and in situ hybridization (ISH) in cancerous and adjacent tissues of 91 HCC patients.Statistical analysis was conducted by SPSS 22.0 software.Results qRT-PCR revealed that the mRNA expression level of miR-150-5P was significantly lower in HCC tissues than adjacent tissues.ISH revealed that the positive rate of miR-150-5P was downregulated in HCC tissues compared to adjacent tissues(x2 =4.958,P =0.046).Chi-square analysis revealed that high miR-150-5P expression was inversely associated with lymph node status of HCC patients,which was statistically significant (x2 =8.617,P =0.006).Kaplan-Meier curves revealed that high miR-150-5P expression was positively correlated with 5-year overall survival rates of HCC patients after surgery,which was also statistically significant(x2 =6.184,P=0.013).Conclusions miR-150-5P expression is downregnlated in HCC,and is negatively correlated with lymph node metastasis and positively correlated with cumulative survival of HCC patients.
ABSTRACT
Objective To introduce a new method performing umbilicus abdominal access during laparoscopy. Methods In a prospec-tive,362 patients received laparoscopic appendectomy in October 2012 to October 2014 were oberserved in this study. The clinical data,the time of the progress of making umbilicus abdominal access,complications and the state of the wound were recorded. Results The performing time of the trocar in umbilicus was (42. 3 ± 27. 1)s. Conclusion The method Cut-open,is simple,fast and save,which is worth to promoting in laparoscopic surgery.
