[Abstract ] Objective To investigate the present situation and demand of nurses training in the different level hospitals of a suburb,so as to provide reference to the building of nursing team.Methods Stratified random sampling was taken in 764 nurses in 20 different level hospitals of a suburb of Beijing.Results In recent 3 years, 31.9% of nurses went out to short -term training and 15.58% of nurses went out to further study for a longer time. The continuous education scores came mainly from own hospital(88.22%),suburb training center(77.75%)and networks(42.54%).About training needs,over half of nurses chose training inside themselves areas,58.38% of nurses chose special short duration training,53.66% of nurses chose further study,48.04% of nurses chose WeChat network platform.About the training content,the first need of training for nursing administrators was nursing safety management (4.65 ±0.54)points,the first need of training for clinical nurses was emergency techniques training (4.41 ±0.69)points.89.14% of nurses would like to have two -way feedback.Conclusion The present situation of nurses training should be improved.Integrating resources and flexible and multiple training methods should be adopted to satisfy nurses training demand.

BACKGROUND: The survival rate of articular chondrocytes is low after traditional cryopreservation,and great differences existed in chondrocytes from surface layer and deep layer,which easily result in graft degeneration and lead to surgery failure.OBJECTIVE: To establish rabbit allograft models of graded frozen articular cartilages with holes made before cryopreservation and to observe the effect of holed cryopreservation on the rabbit articular cartilages.METHODS: Osteochondral plugs taken aseptically from 2 months old rabbits were randomly divided into 3 groups: the experimental group,making holes(3 mm× 3 mm)in articular cartilages and graded freezing; non-hole graded freezing group,non-making holes and graded freezing; cryopreservation group: non-making holes and rapid freezing.The grafts were thawed and transplanted into the relevant articular cartilage defects of recipient rabbits.The grafts differences were observed by gross observation,histochemistry and immunohistochemistry staining.RESULTS AND CONCLUSION: The gross observation,histochemistry and immunohistochemistry staining of the experimental group were superior to the cryopreservation group.Though there were no significant differences between the non-hole graded freezing group and the experimental group,however,the experimental group enhanced the protective effect on cartilage tissue in the middle layer.The graded cryopreservation of articular cartilage gets an advantage over rapid cryopreservation.And the articular cartilage with holes could be preserved successfully in graded cryopreservation,which assures the survival and function of chondrocytes and slows down degrading process of the articular cartilage tissue after thawed and transplanted.

Objective:To investigate the effects of Daidzein on behavior of chronic stress depression rats and the expression of hippocampal brain-derived neurotrophic factor ( BDNF ) , neuropeptide Y ( NPY ) and non-specific immune regulation.Methods: 40 healthy adult male SD rats with body weight(210±19)g,clean grade,were chosen and fed with 1%sucrose solution for 4 d to change drinking habits.On the fifth day rats were subjected to water deprivation for 24 h without fasting.On the sixth day rats were fed with 1%surcrose solution.4 h later, preference of 1% surcrose solution was examined.According to the 1% sucrose solution preference and weight rats were randomly divided into 4 groups,normal control group(CG),model control group,(MG),fluoxetine group(FG,10.0 mg/kg),daidzein group(DG,80.0 mg/kg).At the same time of establishing model,rats were administered orally once a day for 32 d.The depression model was established by chronic unpredictable mild stress model and separation.The behavioral changes of the rats were observed, and expression of BNDF in hippocampus and NPY was measured by Western blot technology and immunohistochemistry.It was observed the proliferation function of lymphocytes,spleen index,the number of peripheral blood leukocytes and antibody-secreting cell function.Results: Compared with the normal control group(CG),the weight of rats with chronic stress protocol was lower, 1%sucrose consumption decreased,scores of rats in the open field test dropped significantly,the immobility time in the forced swimming test prolonged,the level of expression of BNDF and NPY decreased,all the differences above were statistically sig-nificant(P<0.01).Compared with model group,weight of rats in fluoxetine treatment group(FG) and daidzein treatment group(DG)in-creased,sugar consumption,scores in the open field test and the levels of expression of BNDF and NPY significantly increased,the differences were statistically significant( P<0.05 or P<0.01 ).The number of peripheral blood leukocytes and antibody-secreting cell function and proliferation of lymphocytes force in daidzein treatment group was significantly higher than the model group,daidzein dose spleen index was significantly higher than the model group(P<0.01).Conclusion: The daidzein can antagonize depressive symptoms in chronic stress mice,daidzein may increased content of BDNF in hippocampus and NPY protein, and enhanced the role of humoral immune response and lymphocyte proliferation in rats with chronic stress model.The mechanisms of antidepressant effects of daidzein might be related to the increase of content of BDNF in hippocampus and NPY protein and non -specific immune regulation.

Aim To investigate the effects of CYP2C19 polymorphism on the pharmacokinetics and comparative bioavailability of omeprazole in Chinese population.Methods Eighteen healthy male volunteers were selected,of whom 6 were CYP2C19 wild type(w/w),6 were CYP2C19 heterozygous variant(w/m) and the rest were CYP2C19 homozygous variant(m/m).A randomized two-period crossover study was performed.Subjects were assigned to receive test or reference omeprazole as a single oral dose of 40 mg randomly.After a washout period of one week,subjects received the alternative omeprazole formulation.Multiple blood samples of 3 ml were obtained over 12 h after dosing and plasma concentrations of omeprazole were measured by LC/MS method.The modeling of individual pharmacokinetics and the pharmacokinetic parameters of omeprazole were estimated by 3P97.Results The AUC and Cmax of reference omeprazole formulation in w/w,w/m,m/m groups were 1178.44±340.24,2328.10±1011.83,5062.02±1097.29 μg·h·L~(-1) and 602.87±118.25,926.43±134.48,1406.29±233.58 μg·L~(-1),respectively,with significant differences among the three groups(P<0.05).Significant differences were also observed in other pharmacokinetic parameters such as k_e、CL/F、t_(1/2) and Vd/F among the three groups(P<0.05).With regard to test omeprazole formulation,the AUC and C_(max) in w/w,w/m,m/m groups were 1224.82±531.67,2723.34±519.29,5692.49±1575.35 μg·h·L~(-1) and 618.74±231.43,910.67±125.99,1303.31±152.01 μg·L~(-1),respectively,which,as well as k_e,CL/F,t_(1/2) and Vd/F were significant different among the three groups(P<0.05).No significant differences were observed in comparative bioavailability among groups with the values of 94.29%±14.06%,93.08%±11.22%,91.84%±13.03% in w/w,w/m,m/m groups respectively(P>0.05).Conclusions Different CYP2C19 genotypes,leading to functional heterogeneity of CYP2C19,may affect pharmacokinetic profile of omeprazole.Therefore,genotyping CYP2C19 gene before omeprazole therapy will be of great benefit for optimizing individual therapy regimen.There is no significant difference of omeprazole comparative bioavailability with regard to CYP2C19 genetic polymorphism.
