Objective To study the effects of lentiviral vector of microRNA targeting IGF1R gene on growth of liver cancer cells.Methods The complementary DNA containing both sense and antisense Oligo DNA of the targeting sequence was designed,synthesized and cloned into the pPRIME vector,named pPRIME-IGFIR-miR30-shRNA.The viruses were propagated on 293T cells.Viruses were purified by CsCI gradient according to standard techniques,and functional PFU titers were determined by plaque assay on 293 cells.The effect of pPRIME-IGFIR-miR30-shRNA on IGFIR expression of Hep3B、SMMC7721 cells was detected by RT-PCR and Western blot.The antitumor potential of PRIME-IGFIR-miR30-shRNA to Hep3B、SMMC7721 cells was evaluated by CCK-8 assay and Tunel.Results PRIME-IGFIR-miR30-shRNA was constructed successfully.Functional PFU titers of pPRIME-IGFIR-miR30-shRNA were 4.58?109PFU/ml.PRIME-IGFIR-miR30-shRNA inhibited IGFIR expression and the proliferation of Hep3B、SMMC7721 cells.Conclusions PRIME-IGFIR-miR30-shRNA expressing IGFIR-siRNA can inhibit IGFIR expression and may be used for further investigation of gene therapy of liver cancer.

Objective To investigate the value of neutrophil to lymphocyte ratio (NLR) in predicting in-stent restenosis (ISR) in patients with coronary heart disease. Methods We collected the data of 618 patients with coronary heart disease hospitalized in the Department of Cardiology in the First Affiliated Hospital of Kunming Medical University from January 2011 to June 2012. All selected patients underwent coronary angiography and stent implantation, and were divided into two groups according to the average size of NLR. The relationship between the neutrophil to lymphocyte ratio and coronary heart disease in-stent restenosis was investigated. Results There were statistically significant differences in the presence of diabetes, high density lipoprotein, low density lipoprotein, the percentage of neutrophils and lymphocytes in patients between two groups (P<0.05) . We found 13 patients (4.2%) and 32 patients (10.4%) with in-stent restenosis in the first group and the second group, respectively, and there was a statistically significant difference between two groups (P<0.01) . Conclusion Neutrophil to lymphocyte ratio is correlated with ISR,and has clinical value in predicting ISR.

The problems in traditional imaging film and its reporting process were described.A virtual printing server network and a self-service printing service model of image film and its reporting model,established by improving the traditional imaging film and reporting process,could shorten the waiting time of patients after examinations,reduce the errors in imaging film reports,and improve the working efficiency of staff.
