RESUMO
[ ABSTRACT] AIM:To investigate the effects of microRNA145 ( miRNA145 ) on the viability, apoptosis, inva-sion and metastasis of hepatoma HepG2 cells.METHODS: HepG2 cells were randomly allocated into 3 groups: blank control group, empty mimic transfected group and miRNA145 mimic transfected group.Under the induction of Lipofectami-neTM 2000, the recombinant was transfected into HepG2 cells.After transfection, the expression level of miRNA145 was detected by real-time PCR.The protein level of N-cadherin and the mRNA expression levels of miRNA145 and N-cadherin were detected by Western blot and real-time PCR.The cell viability was detected by MTS assay.The cell cycle and apopto-sis were analyzed by flow cytometry.Invasion and metastasis were detected by Transwell assay.RESULTS:Compared with negative control, miRNA145 expression was up-regulated significantly, while the expression of N-cadherin was down-regu-lated significantly.Meanwhile, the cell viability, cell cycle, apoptosis, invasion and metastasis of hepatoma HepG2 cells were all significantly inhibited (P<0.05).CONCLUSION:miRNA145 dramatically inhibits viability, apoptosis, inva-sion and metastasis of hepatoma cells.
RESUMO
Objective To evaluate the application effect of evidence-based care model in hemostasis by compression in patients after renal biopsy.Methods 80 patients undergoing renal biopey from December 2006 to December 2009 in our hospital were chosen as the research object.They were randomly divided into the control group and the observation group with 40 patients in each group.The control group was given routine nursing,and the observation group was treated with evidence-based care model for nusing.The re-bleeding rates,satisfaction degree and the SAS,SDS score,mastering degree of related knowledge,treatment compliance for the two groups before and after nursing were compared.Results The ineidence rate of bleeding in the observation group was higher than the control group,satisfaction degree was higher,and the SAS,SDS score,related knowledge,treatment compliance were all better than the control group,there were significant differences.Conclusions The effect of evidence-based care model in hemostasis by compression after renal biopsy is better.It can significantly reduce the incidence of adverse circumstances and improve the negative emotional state of patients.
RESUMO
Objective To observe differences between repeat and written response in speech recognition tests of short Mandarin monosyllable lists. Methods 12 normal-hearing subjects were tested by 6 short monosyllabic lists. The subjects should repeat and write down.the contents of the tests at the same time, the tester monitors au-rally and records the subjects' reactions. The speech recognition scoring error under different responses at different presentation levels could be obtained by comparing the records of the subjects with the tester. Results The speech recognition scoring of repeat and written response were highly correlated with each other (P<0.01). However, 19(26.4%) out of 72 pairs of test records were inconsistent. The error range of them was from -5% to 10%. When the presentation level was 5 dB HL, the difference among the speech recognition scoring was significant statistically, but not significant when the presentation level at 20, 15, 10 and 0 dB HL. Conclusion The test results of speech audiometry are impacted by different respond methods. In the open-set test, it's supposed that the subjects should make notes while repeating the contents of the tests, then compare with the aural monitoring records of the tester to keep the reliability of the test.
