ABSTRACT
Objective To preliminarily develop a scale to measure the proactive socialization behavior of new nurses and test validity and reliability of the scale, to explore the impact of proactive socialization behavior on turnover intention. Methods Using a questionnaire survey method to investigate 696 new nurses who had worked within three years in nursing organization, structural equation model and hierarchical line regression methods were performed to analyze the data. Results Proactive socialization behavior scale included eight items under one dimension;the consistency coefficient of scale was 0.858;new scale had a good convergent and predictive validity;the proactive socialization behavior of new nurses was significantly negative related to turnover intention (β=-0.236,P<0.01). Conclusions The proactive socialization behavior scale has a good reliability, convergent and predictive validity. Meanwhile, new nurses with higher level of proactive socialization behavior have lower turnover intention. Because they can quickly fit the new environment, role definition and organizational culture, which in turn organization embeddedness is promoted.
ABSTRACT
Objective To build a multi‐level hierarchical structure model of the influencing factors for hierarchical medical system ,to identify the role relationship between all the factors and transmission pathways ,and to recommend on developing China′s hierarchical medical system . Methods Thirty influencing factors were identified in a screening based on literature review for the hierarchical medical system .On such basis ,16 influencing factors were identified by three health policy experts ,which affect operations of the current system .Interpretative structural modeling was called into play in the end to analyze the hierarchy relationship between various influencing factors and the conduction loops .Results There exist among the 16 factors a 3‐level hierarchical structureand two conduction loops .The factor directly limiting the hierarchical medical system is two‐way referral,and most internal core drivers arehuman resources development and governance mechanism.By means of self‐growth and external constraints ,they exert their influence on the operation of hierarchical medical system .Conclusions There are interactive hierarchical effects among the factors ,merging into three node elements of functional role,inter‐entity relationshipand patient participation.
ABSTRACT
Objective To study the influence of survivin targetedly inhibited with antisense oligonucleotide (ASODN)technique on the apoptosis of hepatoma carcinoma cells SMMC-7221,and to clarify the mechanism of promotion effect of survivin-ASODN on the apoptosis of SMMC-7721 cells.Methods The ASODN sequence of survivin marked by FAM fluorescein was designed and synthized. The SMMC-7721 cells were transfected by different concentrations (100,200,300,400,and 600 nmol· L-1 )of survivin-ASODN (ASODN transfection groups),at the same time blank control group and blank liposome control group and sense oligonucleotide (SODN) control group were set up.The apoptotic rates and the changes of cell cycle of the SMMC-7721 cells 24,48,and 72 h after transfected with different concentrations of survivin-ASODN were detected by FCM. The expression levels of survivin were measured by Western blotting method.Results Compared with each control group,24 h after transfection,the apoptotic rates of survivin-ASODN transfected SMMC-7221 cells were increased,the growth of cells was inhibited (P<0.05),and the effects had time-dose dependent tendency.48 h after transfection,the hypodiploid apoptotic peak appeared in ASODN transfection groups before G1 phase, the number of the cells at G0/G1 phase was decreased (P<0.05)and the number of the cells at G2/M phase wsa increased (P<0.05). Compared with each control group,the survivin expression levels in the SMMC-7721 cells in ASODN transfection groups were decreased (P<0.05 ), and the effects of survivin-ASODN was time-dose dependent (P<0.05 ). Conclusion Survivin-ASODN can block the expression of survivin in SMMC-7721 cells and inhibit the proliferation of SMMC-7721 cells by changing the cell cycle and increasing apoptosis in a time-dose dependent manner.
ABSTRACT
Objective To study the changes of CD4 +/CD8 +T cells ratio and TGF -β,IL-4,IL-6 levels in lung cancer patients during the perioperative period and to analyze the clinical significance .Methods Flow cytometer and Elisa were used to analyze the CD 4 +/CD8 +T cells ratio and TGF-β,IL-4,IL-6 levels in peripheral blood sapmles from 20 patients with lung cancer during the perioperative period and 10 healthy con-trolsR. esults Before operation ,the ratios of CD4 +T and CD8 +T cells from 20 patients with lung cancer were (46.26 ±4.26)%and(43.15 ±5.18)%, respectively.On the fifth day after operation ,the ratios of CD4 +T and CD8 +T cells were(44.30 ±4.25)%and(39.80 ±2.53)%.TGF-β,IL-4 and IL-6 levels in 20lung cancer patients were(240.51 ±46.37)pg/mL,(19.85 ±2.52)pg/mL,and(129.28 ±33.06)pg/mL,respectively.On the fifth day after operation,TGF-β,IL-4 and IL-6 levels were(210.79 ±36.94)pg/mL,(17.37 ±2.57) pg/mL,and(107.28 ±27.83) pg/mL.The differences of above parameters between the preoperative period and the fifth day after operation were statistically significant ( P<0.05) . Conclusion The immune suppression oc-curs before its recovery during perioperative period ,the changes of CD4 +/CD8 +T cells ratio and TGF-β,IL-4 and IL-6 levels have significance on monitoring the progress and prognosis of patients with tumor .

ABSTRACT
Objective To investigate the dynamic changes of Th 17 ,NK and IFN-γ,IL-17 in periop-erative patients with lung cancer .Methods Twenty cases of patients with lung cancer surgery were chosen ran-domly.Ten cases of healthy were used as control .We detected the express of Th17,NK,IFN-γand IL-17.Re-sults Compared with the control group , the levels of Th17 and IL -17 increased significantly in lung cancer group(P<0.05);Compared with the pre -operation,the levels of Th17 and IL-17 increased significantly after 1st day of lung cancer surgery .However,the levels of NK and IFN -γdecreased significantly .The expression of Th17 and IL-17 decreased obviously after 5 days of lung cancer surgery .However,the levels of IFN -γin-creased significantly(P<0.05).The correlation analysis showed that there was a positive correlation between Th17 and IL-17A,NK and IFN-γof peripheral blood with lung cancer patients (P<0.01),negative correla-tion between Th17 and NK,IFN-γof peripheral blood with lung cancer patients (P<0.05).Conclusion The immune suppress before activating at perioperative ,it is important for lung cancer patients to detect the levels of Th17,IL-17,NK,IFN-γin peripheral blood .
ABSTRACT
Medical education should combine clinical professional skills with humanities skills,integrate humanities knowledge into vocational education.Taking 2008 grade seven-year program clinical medicine students in the 2nd affiliated hospital of Harbin Medical University as fostering object,we made researches into students' understanding of doctor-patient relationship before practice and their mastering of skills.Through conducting questionnaire,we got to know the effect of humanities practice skill training for seven-year program clinical medicine students.Meanwhile,we compared students' self evaluation results before and after training,discussed on how to improve medical students' communication skills,cultural skills and the reform direction in an aim to guide students to transit from students to clinical doctor.
ABSTRACT
Analysis was conducted and rights concerning teachers,students and patients in practice teaching was defined from the perspectives of medicine,pedagogy,ethnics and law through investigating on reasons leading to problems and conflicts in medical universities' practice right.Effective solutions were proposed from the examination of doctor' s qualification,law and pedagogy.Standardization and legalization of clinical teaching was promoted from the perspective of ethnics.
ABSTRACT
AIM: To observe the influence of Ganoderma lucidum spores on the cytokine IL-1? and c-Fos in the brain tissue of epilepsy rats. METHODS: The IL-1? level was examined by radioimmunoassay and the c-Fos expression was measured by immunohistochemical assay. RESULTS: Comparing the Ganoderma lucidum spores group with the epilepsy model group: c-Fos positive cell count in brain cortex and hippocampus in treatment group was obviously reduced. IL-1? level in brain tissue was also reduced obviously. CONCLUSION: Ganoderma lucidum spores effectively reduces cytokine IL-1? in brain tissue of epilepsy rats, improves the immunity dysfunction and plays a role in anti-epilepsy through suppressing c-Fos expression in epilepsy rats brain tissue and blocking of LRG.
