Methods CNHRMBDS was developed according to refereces and related standard, and then compared with related data set of nursing management. Results There were 179 data elements in the CNHRMBDS. It included all data elements related to human resources for health in China Hospital Basic Data Set Standard 1.0Version, China Public Health Information Classification and Basic Data Set Standard1.0 Version, and Community Health Information Basic Data Set Standard. Twenty-four data elements in the World Health Organization Human Resources for Health Minimum Data Set and 155 data elements in the American Nursing Management Minimum Data Set were found comparable to those in the CNHRMBDS. Conclusions The CNHRMBDS was found complete and able to meet relevant national and in-ternational standards. It should be further developed to be a national standard for health profession.

Objective The purpose of this study was to compare the differences of job satisfaction degree between contract nurses and formal nurses. Methods 350 incumbency clinical nurses were ob-tained from 3 provincial and grade three A hospitals(including nurses in internal medicine, surgical,gyne-cologic,pediatric,emergency departments and ICU). Research instruments used in this study included the self-designed demographic questionnaire and the nurses' job satisfaction scale. Results The level of the overall job satisfaction degree among contract nurses was lower than that of the formal nurses. Of all job satisfaction subscales, the scores of professional opportunities, performance and responsibility,salary and welfare, administration and hospital policy, interpersonal relationships among contract nurses were lower than those of formal nurses. But the scores of scheduling and work conditions, professional traits were higher than those of formal nurses. Conclusions It is advocated to adopt different management and incentive mechanisms to improve the job satisfaction degree for contract nurses according to the differ- ences between contract nurses and formal nurses, so that the nursing staff can be stabilized.

Objective To explore the impact of concentrated teaching, self-help training, intensive training, scenario simulation and other systemic training methods on the health teaching level of community health education staff,and the impact of community health education on cultivation of residents' health behavior before and after training. Methods 60 community doctors and nurses involved in systematic training. Taught concentrated 8 hours every week, and continuous for 4 weeks with medicine, psychology, sociology, pedagogy, aesthetics and production of courseware. Trainees who awarded 80 points or more in examination took part in simulated scene training, which completed a 30-minute design of concentrated health lesson and a 15-minute design of one to one health lesson in written form and multimedia teaching. Teaching effect-site was evaluated by the residents of the community lectures. The impact on cultivation of residents' behaviors was evaluated with ruler evaluation method.Results The community health care workers' teaching ability had significant change after training: plan design (2.32 ± 1.41 vs 4.26 ±0.61 ), lectures (2.63 ±0.89 vs 4.09 ±0.93), teaching skills ( 1.97 ± 1.32 vs 3.89 ±1. 13 ), teaching aids configuration ( 1.68 ± 1. 43 vs 3.97 ± 1. 26 ), educational methods ( 2.01 ± 0. 96 vs 4.03 ±0.82), time control (2.83 ±0.26 vs 4.67 ±0.25), the classroom atmosphere (2.78 ± 1. 13 vs 4.12 ±0.67),courseware ( 2.48 ± 1. 08 vs 3.89 ± 1.02 ) , teaching the image ( 2.15 ± 1.15 vs 4.06 ± 0.78 ), overall evaluation (2.36 ± 1.21 vs 4. 16 ± 0.65 )(P ＜ 0. 0 1 ).

BACKGROUND: Studies are very few regarding the specific reaction of bone marrow mesenchymal stem cells (BMSCs) to activated microglia. Moreover, it remains unclear how MSCs maintain dopaminergic neuronal survival under specific microenvironment.OBJECTIVE: To explore the effect of BMSCs stimulated by activated microglia on dopaminergic neuron survival.METHODS: BMSCs were isolated from Wistar rats by attachment method, and in vitro cultured; microglia was activated, and dopaminergic neurons were cultured by enzyme digestion method. The experiment included 5 groups: BMSCs, microglia, lipopolysaccharide (LPS)+microglia; BMSCs+LPS+microglia groups, in which the dopaminergic neurons were cultured with corresponding culture medium; the dopaminergic neurons alone group was cultured with 10% fetal bovine serum+ DMEM/F12. The effect of different microenvironment on dopaminergic neuron survival and gliocyte-derived neurotrophic factor released from BMSCs were detected by immunofluorescence technique.RESULTS AND CONCLUSION: The release of gliocyte-derived neurotrophic factor in groups involving BMSCs was greater than corresponding control group. Tyrosine hydroxylase immunofluorescence showed that neuronal survival of dopaminergic neurons alone group was 15%, microglia group was 10%, LPS+microglia was 5%, but BMSCs+LPS+microglia group was 28%, significantly greater than the other groups (P < 0.05). In addition, survival of in vitro cultured dopaminergic neurons was decreased with increasing culture duration, but the survival of dopaminergic neurons in group involving BMSCs was significantly greater than corresponding control group. This indicates that microglia activation stimulated BMSCs to upregulate gliocyte-derived neurotrophic factor to prevent dopaminergic neurons from toxic injury, and inhibit delayed death of dopaminergic neurons.

BACKGROUND:Transplantation of mesenchymal stem cells (MSCs) to multiple sclerosis (MS) is a new developed treatment to be given more and more attention.However,whether the MSCs function by cell replacement after going cross the blood-brain barricr or immune suppression needs further confirmation.OBJECTIVE:To establish a steady and effective method of Y chromosome in situ hybridization (ISH) and to detect the distribution of MSCs in a mouse model with MS.DESIGN,TIME AND SETTING:The observational study was performed at the Laboratory of Molecular Immunology,Institute of Healthy Science from September 2007 to February 2009.MATERIALS:A total of 30 C57BL/6 mice,aged 6-8 weeks and weighing 15-20 g,were selected.Female mice were used to establish experimental autoimmune encephalomyelitis (EAE).METHODS:Y chromosme specific DNA probe labled with digoxine (DIG) was designed and ISH was performed to confirm that the designed probe was Y chromosome specific and biologically sensitive.We transplanted the MSCs from male mice into the female EAE mice,and tracked the MSCs by Y chromosome ISH.MAIN OUTCOME MEASRUES:Distribution of MSCs in mice with EAE was observed under the optical and fluorescence microscope.RESULTS:The probe was confirmed to be Y chromosome specific and biologically sensitive.What's more,a steady and effective method of ISH was established.Some MSCs were detected in the periphery organs-spleen and lymph node of mice with EAE;seldom in spinal cord which indicated that MSCs might play its roles by immune suppression.CONCLUSION:Some MSCs were detected in the periphery organs-spleen and lymph node of mice with EAE,but seldom in spinal cord in the central nervous system.

OBJECTIVE:To observe the antiviral effects of Qingre jiedu soft capsule(ADSC)against influenza A H1N1 virus in vivo,and to provide a experimental support for clinical therapy of influenza A H1N1 virus. METHODS:BALB/c mice were ran-domly divided into normal control group,model control group,positive drug high-dose,medium-dose and low-dose groups [oselta-mivir phosphate capsule,0.04,0.02,0.01 g/(kg·d)] and ADSC high-dose,medium-dose and low-dose groups [1.5,0.75,0.375 g/(kg·d)].Except for normal control group,others groups were given influenza A H1N1 virus with titer 1.6×10-5.2 via nasal cavity to induce poisoned mice model;6-8 h after modeling,they were given relevant medicine intragastrically,once a day,for 5 days. After medication,the change of body weight within 7 d were observed in mice;the mortality and death prevention rate within 15 d,mean survival days(MSDs)were calculated in mice.Other mice were selected and grouped,and they were given same drugs as above. 8 h after last medication,lung index and inhibition rate of lung index were determined in mice.RESULTS:In model control group,the body weight of mice decreased significantly since 5th day,and mice death was beginning to occur since 8th day(mortal-ity of 85.7% within 15 d);the lung index was increased significantly compared to normal control group (P<0.01). Both ADSC and oseltamivir phosphate capsule could slow down the decrease of body weight in mice,decreased the mortality and lung index of mice,and prolonged MSDs;the MSDs of mice in ADSC high-dose,positive drug high-dose and medium-dose groups were signifi-cantly higher than model control group(P<0.05),and lung index was significantly lower than model control group except that of ADSC low-dose group(P<0.05). CONCLUSIONS:ADSC has certain antiviral effect against influenza A H1N1 virus in vivo.

Objective To explore the change of serum Apelin level and its relationship with insulin resistance (IR) in infertility patients with polycystic ovarian syndrome (PCOS). Methods Ninety-eight infertility patients with PCOS (PCOS group) and 72 infertility patients without PCOS (non-PCOS group) visiting our hospital for the first time from January 2011 to June 2012 were selected. The BMI , serum Apelin level (detected by ELISA), fasting blood glucose (FPG, detected by glucose oxidase method), fasting insulin (Fins, detected by chemiluminescence), and homeostasis model assessment of insulin resistance index (HOMA-IR) of the two groups were detected. Results The serum Apelin level and HOMA-IR in PCOS patients were higher than those in non-PCOS patients (3.28 ± 1.24 vs. 1.94 ± 0.78, P < 0.05; 3.84 ± 1.23 vs. 2.14 ± 0.77,P < 0.05). Pearson correlation analysis showed that serum Apelin level was positively correlated with HOMA-IR in PCOS patients (r=0.65, P<0.01). Conclusions The serum Apelin level in infertility patients with PCOS increased evidently, and was positively correlated with HOMA-IR; which indicated that Apelin may involve in the development of IR in infertility patients with PCOS.
