Objective To investigate the neurosurgery nurses turnover intention and the psychological contract status to analyze the relationship between them. Methods The Departure Will Scale and Questionnaire of Psychological Contract were used to survey 128 neurosurgery nurses from seven general hospitals in Lishui city. Results Of neurosurgery nurses turnover intention scale was (2.24±0.71) points, whose leaving intend was stronger;Psychological contract items was (4.17±0.67) points, which organization responsibility score wasbelow employees responsibility; Hierarchical regression analysis showed that the psychological contract in the organization responsibility (organization specification responsibility, organization, personal responsibility and organizational development responsibility) could predict neurosurgery nurses′ willingness to leave, which could be able to explain their willingness to leave 13.5%of the variation. Conclusions Neurosurgery nurses′willingness to leave is strong, and psychological contract is an important factors affecting the will of their departure.

BACKGROUND: The incidence of mental problems in adolescents is increasingly higher and has gradually become an important factor affecting their health and growth.OBJECTIVE: To probe into the mental health status and its influencing factors in adolescents in some cities and rural areas in Hubei Province.DESIGN: Clustering stratified random sampling, cross-sectional survey.SETTING: Department of Maternal, Child and Adolescent Health, Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: According to the selected investigation spots of National Surveillance of Constitution and Health of Students, we selected representative urban areas (Wuhan City and Huangshi City) and rural areas (Yun County, Xiantao City, and Xiaogan City) in Hubei Province as sample spots. Totally 1 498 adolescents, aged 16-18 years, were surveyed by clustering stratified random sampling. There were 605 adolescents in urban group and 893 in rural group.METHODS: The self-made survey scale was used to investigate general conditions, such as age, parents' occupation and educational level, family type, social atmosphere, school type and atmosphere, and interpersonal relationship. Symptom Checklist-90 (SCL-90) was used to determine the adolescents' mentalhealth status; 9 subscales (somatization, obsessivecompulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychosis) were set as the observation indexes. SCL-90 is an inventory which is rated on a 5-point scale. Factor score of SCL-90 ≥ 3 or total score ≥ 160 was considered mental disorders. The family educational pattern was investigated through Egma Minnen av Bardndosnaupporstran(EMBU) by questionnaires. It contained positive rearing pattern and negative rearing pattern. Positive rearing pattern (namely, affectional warmth and understanding) contributes to mental health, while negative rearing pattern (e.g. punishment, firm control, excessive interference, partialism or rejection, denial and excessive protection) is adverse to mental health. The family environment was investigated with Family Environment Scale(FES). Four subscales (intimacy, conflict, intellectual-cultural orientation, and positive-recreational orientation) with high reliability and validity were set as indexes. All participants were given unified instructions and required to fill in anonymous questionnaires. The questionnaires were then collected by the teacher in charge of the class.Some indexes of adolescents in the urban and rural areas were observed including the score of SCL-90 and its relation with general conditions,parental rearing pattern and family environment quality. The total scores of symptom checklist 90 were set as dependent variables for stepwise regression analysis of related factors.MAIN OUTCOME MEASURES:①The incidence of mental health ,gender and regional difference of adolescents in some cities and rural areas in Hubei province; ②The score of SCL-90 and its comparison with national norm;③Correlation analysis of the total scores of SCL-90 with general condition and parents' educational type.RESULTS: ① The general incidence of mental disorders was 18.13 ％ in the 1 498 adolescents in Hubei province. It was 18.20% in boys and 18.04% in girls with no significant difference (P ＞ 0.05). Regional differences: The incidence in rural areas [23.74% (212/893)] was significantly higher than that in urban areas [16.69% (101/605), P ＜ 0.05]. Among all kinds of mental disorders, compulsion, interpersonal sensitivity, hostility,paranoid ideation, and depression were more common. ② Comparison with the national norm: The factor scores of SCL-90 and family environmentalquality were significantly lower that those of the national norm.③ Single factor analysis: The total score of SCL-90 was obviously correlated with age, gender, parents' educational level and expectation, and school atmosphere (P ＞ 0.01). It was negatively correlated with positive rearing pattern (affectional warm, understanding) (P ＞ 0.01), but positively correlated with negative rearing pattern (punishment, firm control, excessive interference,partialism or rejection, and denial). It had significant positive correlation with conflict and significant negative correlation with intimacy, intellectualcultural orientation and positive-recreational orientation(P ＞ 0.01).④Multiple factor analysis: The mental health status of the students was closely related to age, gender, parents' educational level and expectation, interpersonal sensitivity as well as school atmosphere, parental rearing pattern,and quality of family environment.CONCLUSION: The incidence of mental problems in adolescents in some urban and rural areas in Hubei Province is relatively high. Score factors of SCL-90 are all higher than those of the national norm and the mental health level is poor. This has obvious correlation with family factors including age, gender, parents' educational level and expectation, and school atmosphere. Moreover, the quality of family environment and parental rearing pattern are the major factors affecting their mental health.

Mortality is a key index for assessing technical level and treatment quality of hospital. We filtered and analyzed the literatures about the influence of nurse factors on patient mortality out of China in recent years to guide the study within China. We found the nurse factors impacting mortality included workload, configuration of nursing staff, education status and working environment. Those findings point out the direction of the research on relationship between nurse factors and patient mortality in China, which has great significance.

BACKGROUND:Although bone marrow mesenchymal stem cels from multiple myeloma patients present a variety of abnormalities, it is unclear how these abnormal mesenchymal stem cels influence the chemotactic function of myeloma cel lines.
OBJECTIVE:To investigate thein vitro effects of bone marrow mesenchymal stem cels from normal donors versus multiple myeloma patients on the chemotactic capacity of myeloma cel lines.
METHODS:In vitro cultured bone marrow mesenchymal stem cels derived from either normal donors (N-MSCs group) or newly-diagnosed multiple myeloma patients (MN-MSCs group) were directly co-cultured with U266 cels, in the presence or absence of bortezomib; and then harvested U266 cels were assayed for Transwel migration and mRAN expression of chemotaxis-related genes. U266 Transwel migration to conditioned medium derived from either N-MSCs or MN-MSCs was also tested.
RESULTS AND CONCLUSION:After co-cultured with N-MSCs or MN-MSCs, U266 cels harvested from MN-MSCs group showed increased spontaneous Transwel migration and up-regulated CCR1 mRNA level than those from N-MSCs group (P < 0.05), whatever bortezomib was present or not. However, there was no evident difference between U266 cel Transwel migration to conditioned medium derived from either MM-MSCs group or N-MSCs group. Our study implies that there may be some intrinsic aberrance in bone marrow mesenchymal stem cels derived from multiple myeloma patients, which can modulate the chemotactic migration of myeloma cel lines when they directly interact with each other.

Aim The present study was designed to investigate the growth inhibition and anti-angiogenesis of arsenic trioxide (As 2O 3) on B16 cells xenografts in C57BL/6J mice and observe the effects of As 2O 3 on cell proliferation, cell morphology, cell cycle and apoptosis in vitro. Methods Mice melanoma cell line B16 was transplanted into C57BL/6J mice. The weight of tumor and percent of tumor development were examined after As 2O 3 intraperitoneal administration. HE staining and immunohistochemistry for Ⅷ-R Ag were performed to detect the microvessel density in tumor tissues. CellTiter 96 Aqueous One was used to determine the cell proliferation. Giemsa and Feulgen staining were used to observe the morphological changes of the cells. Cell cycle and apoptosis were analyzed by flow cytometry (FCM). Results As 2O 3 significantly inhibited the tumor growth in vivo, with an inhibitory rate of 81.61%. The microvessel density in tumor tissues was obviously reduced after treated with As 2O 3. There was obviously a concentration-dependent relationship between As 2O 3 and the inhibition of B16 cells proliferation (P

Objective To investigate the change of the distribution of peripheral blood lymphocyte subsets,before and after treated by infliximab (IFX) in patients with inflammatory bowel disease (IBD).Methods From September 2008 to January 2013,a total of 20 patients with IBD accepted more than three times of IFX treatment and on time follow-up were collected,11 cases of ulcerative colitis (UC) and nine of Crohn's disease (CD).At same time,20 healthy individuals were enrolled as healthy control group.The efficacy of IFX on patients with UC or CD was evaluated according to Mayo score and simplified Crohn's disease active index (CDAI) before and after treatment.Fasting blood of healthy control group,one day before IFX treatment and in 24 to 72 hours after the third time of IFX injection of IBD patients was collected.The percentage of total T lymphocyte,total B lymphocyte,CD4+ T lymphocyte,CD8+ T lymphocyte and natural killer (NK) cell in lymphocyte was determined by fluorescent labeled monoclonal antibodies and flow cytometry.Independent sample t-test was performed for comparison between two groups.Analysis of variance was for comparison among three groups.Results Three of 11 patients with UC achieved clinical remission,three cases were clinical improved and five cases were ineffectiveness.Among nine CD patients,one achieved clinical remission,six cases were clinical improved and two cases were ineffectiveness.Of UC patients,the percentage of total T lymphocyte before and after treatment ((84.2±8.1) ％ and (82.1±6.2)％),the percentage of CD8+ T lymphocyte before treatment ((40.0± 13.2)％) were all higher than that of healthy control group ((74.7±10.7)％ and (30.5±11.9) ％),while the percentage of NK cell before and after treatment ((5.1±2.8)％ and (7.8±4.3)％) were all lower than that of healthy control group ((13.7 ±7.8)％) and the differences were statistically significant (t=2.540,2.074,2.251,3.464 and 2.063,all P＜0.05).Compared with healthy controls,there were no significant differences in the percentage of total B lymphocyte and CD4+ T lymphocyte of UC patients before and after treatment,the percentage of total T lymphocyte,total B lymphocyte,CD4+ T lymphocyte,CD8+T lymphocyte and NK cell of CD patients before and after treatment (all P＞0.05).Before treatment,there were significant differences among effective treatment group,ineffective treatment group and healthy control group in the percentage of total T lymphocyte,CD8+ T lymphocyte and NK cell (F=4.095,4.571 and 7.432,all P＜0.05),of those there were significant differences between ineffective treatment group ((88.3 ± 8.2) ％,(44.4 ± 11.5) ％ and (4.6 ± 3.2) ％) and healthy control group (t=2.902,2.105 and 3.647,all P＜0.05).Conclusion The percentage of peripheral blood total T lymphocyte and CD8+T lymphocyte increase in active IBD patients with ineffective IFX treatment,however the percentage of NK cell decreases.

In order to identify family factors obviously relevant to aggression, and offer a theoretical foundation for the prevention of aggression, 4010 students from primary and secondary schools in 5 different areas in Hubei province were surveyed. The Child Behavior Checklist " parents' form" (Chinese version) and the four scales of Family Environment Scale were used. A multiple logistic regression was used to identify risk factors of children's and adolescents' aggressive behavior. The results showed that maternal education, paternal occupation, family type, parental child-rearing attitude and patterns, students' interpersonal relationship were significantly associated with the children's and adolescents' aggression. The risk factors of aggression were parental child-rearing patterns, peer relationship, teacher-student relationship, and family conflicts.

Objective To observe the role of intermediate conductance calcium?activated potassium channels (KCa3.1) in alkalinization and β?glycerophosphate induced vascular calcification. Methods Vascular smooth muscle cells (VSMCs) and aortic rings were obtained from rat thoracic aorta, and then randomly divided into control group (pH was provided into 7.4, 8.0), high phosphorus groups (pH was provided into 7.4, 7.7 and 8.0, VSMCs in three groups were treated with 10 mmol/L β?glycerophosphate; HCl and NaHCO3 were used to adjust the pH) and TRAM?34 group (20 nmol/L was added into pH8.0 high phosphorus dulbecco's modified eagle's medium). Calcium deposition and alkaline phosphatase (ALP) activity were measured by Alizarin red staining, calcium content and enzyme linked immunosorbent assay after cells were simulated for 12 days. Intracellular free Ca2 + was measured by ELISA. The expression of KCa3.1, runt?related transcription factor 2 (Runx2) were detected by RT?PCR and Western blotting 4 days after cells were stimulated. Calcium deposition was measured by von Kossa staining and calcium content after aortic rings were cultured for 12 days. The expressions of KCa3.1 and Runx2 were detected by immunohistochemistry after aortic rings were cultured for 4 days. Results Compared with control group, calcification in VSMCs and aortic rings were significantly increased in high phosphorus group (P<0.05) while decreased in TRAM?34 group (P<0.05). Compared with control group, the expressions of KCa3.1, Runx2 and the activity of ALP in high phosphorus groups were increased (P<0.05) while decreased in TRAM?34 group (P<0.05). Besides, expressions of Runx2 and KCa3.1 were augmented as the pH was higher (P<0.05). The expression of Runx2 in aortic rings was the same situation. Besides, the Ca2+ influx was blocked by TRAM?34 (P<0.05). Conclusions Alkalinization contributes to β?glycerophosphate induced VSMCs calcification through increase of Ca2 + influx, up?regulation of KCa3.1 and promotion of osteogenic/chondrogenic differentiation.

Objective To investigate proliferation and apoptosis of colonic epithelial cells from ulcerative colitis (UC)patients with active new-onset,remission and active recurrent stages,and to study the effects of 5-aminosalicylic acid (5-ASA)on proliferation and apoptosis of colonic epithelial cells during the treatment of inducing remission and maintanence remission. Methods From January 2002 to December 2012,twelve patients with mild-to-moderate UC who received treatment and long-term follow-up and achieved remission with 5-ASA and received long-term maintanence treatment with it were assigned to UC group.At the same period,10 healthy individuals with negative endoscopy results or solitary colonic polyp were assigned to control group.The biopsy tissues from colonoscopy for pathological examination of patients in UC group at new-onset active stage,remission stage and recurrence stage were obtained.Levels of proliferation marker Ki-67 and apoptosis of colonic epithelial cells were determined by immunohistochemistry and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL)assay,respectively.Data were expressed by median(lower quartile,upper quartile).Kruskal-Wallis test and Mann-Whitney test were performed to compare the differences between groups and Bonferroni method was used for correction.Results The median proliferation indexes (PI)of colonic epithelial cells of UC patients at new-onset active period,remission period and recurrent active period were 31 .65 % (19.14%,39.66%), 12.30% (11 .11 %,14.10%) and 44.15 % (33.65 %,52.45 %), respectively,which were all higher than those of control group (7.89% (6.54%,8.86%))there were statistically significant differentes among four groups (H =30.033,P <0.01 );those of new onset active period and recurrent active period were both higher than remission period,and the differences were statistically significant (all P <0.05/6).The median apoptosis indexes (AI)of colonic epithelial cells in UC patients at new-onset active period,remission period and recurrent active period were 24.18%(17.81 %,27.16%),44.19% (43.41 %,50.55 %),41 .24% (33.78%,46.24%),respectively,which were all higher than those of control group (2.65 %(2.48%,2.98%)),there were statistically significant differences among four groups (H =31 .563,P <0.01);and those of remission and recurrent active period were both higher than new-onset active period (all P <0.05/6).The median apoptosis/proliferation ratios of control group,new onset active period,remission period and recurrent active period were 0.320 0 (0.275 5 ,0.425 0),0.749 9 (0.634 9,1 .115 8 ),3.282 8 (3.133 1 ,4.406 8 )and 1 .008 2 (0.801 9, 1 .099 2),respectively,there were statically significant differences among four groups (H =29.441 ,P <0.01);those of new onset active period and recurrent active period were both lower than that of remission period and the differnces were statistically significant (both P <0.05/6 ).Conclusions Proliferation and apoptosis imbalance in colonic epithelial cells of UC patients is one of the important mechanisms for the pathgensis of UC.5-ASA does not promote the proliferation of epithelial cells during UC remission period.

Objective To investigate whether paclitaxel can efficiently induce the apoptosis of ovarian cell HO-8910,and to study the relationship between the apoptosis of cells and the cell cycle.Methods With the treatment of paclitaxel with different concentrations and different time,the morphologic change of HO-8910 ovarian cells was observed using fluorescence microscopy and transmission electron microscopy(TEM),and the apoptosis of cells and the changes of cell cycle were determined by flow cytometry(FCM). Results The typical changes of HO-8910 cell apoptosis were observed by TEM and Fluorescence microscopy.With the treatment of paclitaxel,the HO-8910 ovarian cells were firstly arrested in G_2/M phase,and the typical ultrastructural changes of apoptosis were appeared only after the cells were apparently arrested in G_2/M phase.Conclusion Paclitaxel can induce the apoptosis of HO-8910 cells and the apoptosis is associated with the blockage of G_2/M phase in cell cycle.
