Objective To improve the influence on physical and mental health of nurses caused by frequent night shifts in order to stabilize the nursing care ranks and sublimate comprehensively the quality of nursing. Methods We selected night shift nurses working at clinical departments at random, divided into the experimental group and the control group.The experimental group was provided coffee and milk at the fixed period of night time, however, the control group was not supplied during the night shift.We designed questionnaire according to the Comell Medical Index (CMI), the Trait Coping Style Questionnaire (TCSQ) and the needing of the research. In addition, we determined the concentrations of adrenal eortisol and blood glucose in the experimental group and the control group. Results The experimental group compared with the control group had stronger excitability, more active enthusiasm. Coffee and milk eliminated sleepiness during work without affecting sleep after work, and increased significantly the concentrations of adrenal cortisol and blood glucose, the difference had statistical significance. Conclusions With the supply of specific nutrients to night shift nurses can interfere and eliminate anthropogenicly night shift nurses sleepiness and fatigue, reduce nursing accident rate, and improve quality of care.

Objective To simulate the hemodynamic feature in cerebral bridging veins (BVs), in order to provide a morphologic basis for the pathogenesis explanation and imaging diagnosis of cerebral venous thrombosis (CVT). MethodsTotally 6 human cadavers (12 sides) were examined in this study. Each head of the cadavers was injected with blue-coloured latex via the superior sagittal sinus (SSS) and internal jugular veins. The diamter and the angle of BVs entering SSS were measured. Based on the data of cadavers and computational fluid dynamics software pack, the hemodynamic models were established. The wall shear stress (WSS) was carefully studied and compared between different models. Results The total of 137 BVs formed two clusters along the SSS: anterior group and posterior group. Compared with anterior group BVs, the diameter of posterior group BVs was large, and the angle was smaller. In 137 models,when the diameter of a BV was more than 1.2mm, and the angle was between 65 and 105 degree, the local WSS decreased in the downstream wall of SSS. When the diameter of a BV was more than 1.2mm, and the angle was less than 65 degree, the local WSS decreased in the downstream wall of SSS and the upstream wall of BVs. The minimum WSS in BVs was 63% of the minimum WSS in SSS. Compared with the anterior group BVs, the minimum WSS in the wall of posterior group BVs was samller, and the distance from the minimum WSS to the dural entrance was longer. Conclusion CVT occurs easily when the diamter of a BV is more than 1.2mm and the angle is less than 65 degree. The embolus forms early in the upstream wall of BVs entering the posterior part of SSS.

Objective To detect the PML-RARα fusion gene expression of APL patients with FISH and fluorescent quantitative PCR and discuss the sensitivity and specificity of two techniques. Methods The detection of the PML-RARα fusion gene expression of 75 APL patients with FISH and fluorescent quantitative PCR were carried out simultaneously. Results Eighty eight patients of primary and relapse or remission phases were examinated and total conformity rate was 96.59 %. Fourteen primary patients were detected and conformity rate was 100 %. Seventy four relapse or remission patients were detected and conformity rate was 95.95 %. Stem cell essays were detected for six times and conformity rate was 100 %. Conclusion The sensitivity of FISH and fluorescent quantitative PCR is identical for primary APL patients and FISH is more sensitive. But the sensitivity of FISH is weaker than that of fluorescent quantitative PCR for detection of residue disease.

Objective To discuss the efficacy of intravesical instillation of sodium hyaluronate for the treatment of cystitis glandularis after transurethral resection.Methods 85 patients (9 male and 76 female,age range 37-70 years,mean age 51) who were diagnosed as CG in China-Japan Union Hospital of Jilin University underwent transurethral resection.After the operation they were divided into three groups randomly according to different intravescal instillation:sodium hyaluronate for group A,epirubicin for group B and no medicine for group C.The group A started to instill with sodium hyaluronate 40mg once a week for four weeks,and then once a month for four months.The group B did the same way of intravesical instillation of epirubicin.All the patients were followed-up for 12 months.The cystoscopy was done every three months to detect recurrence and the clinical symptom score was evaluated at 1,3,6 and 12 months.Results No patients in group A treated by sodium hyaluronate relapsed but 6 cases and 9 cases in group B and group C respectively.Recurrence rate of group A is significant low compared with group B and C (P ＜ 0.05).The scores of clinical symptom score appendix after 1,3,6 and 12 months for group A were (3.18 ± 1.44),(1.29 ±0.66),(1.25 ±0.65) and (1.21 ±0.63),respectively.It was (3.37 ±1.62),(3.33 ±1.59),(1.37±0.74) and (1.30±0.61) for group B,and (3.47±1.81),(3.40±1.52),(3.27±1.41) and (3.23 ± 1.19) for group C.Compare the score of clinical symptom in the same group,there were significant differences for the score after 3 months compare with the score after 1 month in group A (P ＜ 0.05).But in group B,the significant differences showed after 6 months (P ＜ 0.05).There was no significant difference in group C (P ＞ 0.05) in the whole year.Conclusions Intravesical sodium hyaluronate therapy can effectively decline the recurrence rate of cystitis glandularis after transurethral resection.It could also significantly improve the urinary tract symptoms.
