ABSTRACT

Objective To explore the effects of BSA on hypoxia inducible factor/hypoxia response element (HIF/HRE) transcription activity in rat tubular epithelial cells (NRK-52E) with HRE-Luc reporter plasmid.Methods Luciferin activity of NRK-52E cells incubated by a medium contained BSA in varying concentration (0,5,10,20 mg/ml) and stimulus duration (24,48,72 h) was detected by dual luciferase detecting system based on HRE-Luc reporter plasmid and HIF-1 α expression was detected by Western blotting.Results HIF/HRE transcription activity of NRK-52E cells was increased in BSA incubation group (10 mg/ml,48 h) compared with blank control (BSA 0 mg/ml,48 h) [(2.59±0.35)vs (1.03±0.09),P=0.000].HIF-1α expression of NRK-52E cells was increased in BSA incubation group (20 mg/ml,48 h) compared with blank control (BSA 0 mg/ml,24 h) [(0.052±0.010) vs (0.014±0.003),P=0.000].Conclusion Albumin can increase HIF/HRE transcription activity of TEC.

ABSTRACT

Objective To explore the effect of applying problem-based learning (PBL) combined with ' pre-resident physician' teaching model in clinical practice in the nephrology department.Methods Sixty students in clinical practice were divided into two groups:experimental group and control group.The students in experimental group were received PBL in combination with 'pre-resident physician' teaching model while those in control group were received traditional teaching model.The effect was evaluated according to the results of theoretic examination and investigation.The results were analyzed by x2 test and P < 0.05 signified statistically significant.Results The average score of theoretic examination in experimental group was 80.22 while that in control group was 76.53.The students in experimental group had significant higher score than those in control group (P < 0.05 ).The overall satisfaction degree was 93.00% in experimental group concerning the 8 indicators in PBL combined 'pre-resident physician' teaching model,while that was 73.75 % in control group concerning the 8 indicators in traditional teaching mode.Concerning the aspects of teaching flexibility,arousing learning interest,training literature capacity and improving ability of independent problem solving,the satisfaction degree was higher in experimental group than in control group (P < 0.05 ).Conclusion PBL in combination with ' pre-resident physician' teaching model has evident advantages in clinical practice in nephrology department.
