Objective To evaluate the strictness and self-consistency of the charge nurses in the nurses examination using venipunctnre trocar operation as research object.Methods FACETS,the polyhedral Rasch software was used in the examination.Results The strictness and self-consistency of charge nurses were evidently different.Conclusions The variable strictness and self-consistency of the charge nurses in the examination leads to unreliability of the results.Developing a scientific and reliable evaluation system is essential to improve the ability of the teaching nurses and the student nurses as well as the hospital nursing quality.

Objective To study the inhibition of AP-1 transcription factor activity by Hint1 gene over expression in HepG2 cell lines. Methods The Hintl gene was amplified, and then was inserted into the pcDNA3/HA eukaryotic expression plasmid. The constructed pHA-Hint1 plasmid was confirmed by DNA sequencing. The pHA-Hint1 was transfected into the HepG2 human hepatoma cells. Semi-quantitative RT-PCR and Western-blot were used to detecte the expression of HA-Hint1. The HepG2 cells were co-transfected with pHA-Hint1 and pAP-1/Luc luciferase reporter. At 36 h after transfection, luciferase assay system was used to detect the AP-1 transcription factor activity. Results The constructed pHA-Hint1 was confirmed by DNA sequencing, pHA-Hint1 gene transduction through lipofectine induced over-expression in HA-Hint1 mRNA (t =3.89, P<0.05) and HA-Hintl protein (t=3. 12, P<0.05). Co-transfection of Hint1 gene inhibits AP-1 luciferase activity. Cotransfection with increased concentration of a pHA-Hint1 plasmid (0 μg/ml, 0. 5 μg/ml, 1.0 μg/ml, 1.5 μg/ml, 2. 0 μg/ml) produced a concentration-dependent inhibition of AP-1 transcription factor activity. At the concentration of 1.5 μg/ml, and 2.0 μg/ml, the activity inhibition reaches significant difference ( F = 72. 009, P < 0. 05 ). Conclusion Over-expression of Hintl can, at least in part, inhibit the AP-1 transcription factor activity in HepG2 cells.

AIM:To evaluate the efficacy and safety of gabapentin in the treatment of migraine.METHODS:A randomized,double-blind,placebo-controlled study was taken.104 patients(aged 18 to 60 year)with migraine were randomly assigned to receive placebo(control group,49 patients)or gabapentin(experimental group,55 patients)for 4 weeks.The efficacy,side effects,TCD and EEG were assessed at the beginning of trials,and 4th,8th weeks.RESULTS:Comparing with the placebo group,the frequency,duration and intensity of migraine were markedly decreased in gabapentin group,there was significant difference between groups(P0.05).CONCLUSION:Gabapentin is an effective and safe agent from migraine.

Objective:To explore the influence factors on amplification of single cell duplex-nested PCR.Methods:The mutational loci region CD41-42 and IVS-Ⅱ654 of ?-globin gene were amplified by duplex-nested PCR with different combination of primers concentration, different Taq DNA polymerases, different neutralization buffers and with or without predenaturation at 98 ℃ before the PCR amplification in single lymphocyte or single blastomere, thus, to investigate the influence of these factors on the amplification efficiency of PCR.Results:TaKaRa EX Taq was the most efficient Taq DNA ploymerase among different Taq DNA ploymerases; primer pair R1+F1 at final concertration of 0.25 ?mol/L and R2+F2 at 0.3 ?mol/L were the most efficient ones in amplification among different combinations of primers concentrations; the amplification efficiency in neutralization buffer-1 (200 mmol/L Tricine) was obviously higher than that of neutralization buffer-2 (900 mmol/L Tris-HCl, pH 8.3/300 mmol/L KCl/200 mmol/L HCl)(P0.05). Conclusion:There were remarkable differences of the amplification efficiency of single cell duplex-nested PCR while using different combination of primers concentrations, different Taq DNA polymerases, different neutralization buffers. However, predenaturation at 98 ℃ before the single cell PCR amplification could not improve the PCR amplification efficiency

Objective To explore the relationship between galactose-induced apoptosis of lens epithelial cells and cataractogenesis.Methods Galactose was injected retrobulbarly into Wistar rats.The opacity of lens was examined by slit lamp.The expression of C-MYC was measured by flow cytometer.The apoptosis of lens epithelial cells was observed by TUNEL techniques.Results More than 50 percent of lenses were in the Ⅱ stage of cataractogenesis on the(7 d) after galactose induction;Eighty-seven percent of lenses were in the Ⅳ-Ⅴ stage on the(14 d),and 100 percent of lenses were in the Ⅳ-Ⅴ stage on the(24 d).The rate of apoptotic cell on the(7 d) and on the(14 d) after galactose induction was respectively 5.6%～8.4% and 30.2%～41.8%,and 60% apoptotic cells were observed on the(24 d).The levels of C-MYC expression in lens epithelial cells induced by galactose on the(7 d) and(14 d) were higher than that of normal lenses,but the level of C-MYC expression backed to normal level on the(24 d).Conclusion It was suggested that there are some apoptosis of the lens epithelial cells during galactose-induced cataractogenesis and that the apoptosis of the lens epithelial cells might be caused by higher expression of C-MYC.
