Objective To explore the relationship between the emotional labor and personality of the health care workers. Methods 168 health care workers in 6 hospitals of Shandong province were surveyed to complete the Emotional Labor Scale and the revised NEO personality inventory(NEO-PI-R). Results The first strategy of emotional labor that workers usually used was natural acting (5.17±1.15),the next one was deep act-ing (4.74±0.78) and the last was surface acting(3.88±1.21). The correlation analysis showed that the extro-version had a negative correlation (r=-0.20, P < 0.05) with the surface acting and a positive correlation (r=0. 31, P<0.01) with the deep acting. The agreeableness had a positive correlation (r=0.22, P < 0.05) with the nat-ural acting. The conscientiousness had a positive correlation (r=0.25, P<0.05) with the deep acting. The extro-version had significant negative influence on surface acting and significant positive influence on deep acting. The a-greeableness had positive significant effect on natural acting and the conscientiousness had positive significant effect on deep acting. Conclusion Personality influenced the emotional labor and gender,age,work tenure and ed-ucational had significant effect on emotional labor.

[Method]From March 2000 to March 2007, thirty hips in 25 adult patients with osteoarthritis secondary to acetabular dysplasia undergoing total hip replacement with cementless joint components were included in this study. Of the patients, 5 were male and 20 were female.Their ages ranged from 35 to 55 years with an average age of 55 years. The patients mainly complained of pain and claudication. According to the Hartofilakidis classification , Semi-dislocation occurred in 21 hips and high-dislocation in 9 hips.Five patients underwent bilateral total hip replacements and twenty patients had unilateral total hip replacement.[Result]The duration of follow-up ranged from 8 months to 7 years ( average 3 years and 9 months ) . The average Harris score was increased from 36.09 to 88.21 points, They could take care of themselves and returned to their previous job. All the patients were pain-free and there was no sign of aseptic looseing or subsidence.[Conclusion]Total hip replacement with cementless joint components is an effective method for the treatment of osteoarthritis secondray to acetabular dysplasia in adults.The key point to the success for operation are appropriate cementless joint components, deepened medial wall of the acetabulum and improved the techniques of bone graft in the true acetabulum.

[Objective]To investigate the therapeutic results of grafting with bioactive glass and autologous bone marrow for simple bone cyst in teenagers. [Method]From April 2005 to October 2007,16 teenagers with simple bone cyst were reported.There were ten males and six females with a mean age of 18.5 years(range 12 to 30 years).Eight cysts were in the proximal humerus,five in the proximal femur,two in the proximal tibial and one in the distal end of radius.Lining of cavity was removed thoroughly with a curet.The cyst cavity was filled with the mixtures of 45s bioactive glass and autogenous red bone marrow.Five cases of pathologic fracture were fixed with steel plate or intramedullary nail.[Result]All 16 cases of cysts were ossified radiolo gically within six months,with an average time to syst healing of 18 week.A follow-up of 6 to 32 months(mean 18 months) showed satisfactory healing without complications.[Conclusion]The combined grafting with bioactive glass and autologous bone marrow appears to be an effective and simple treatment for simple bone cyst in teenagers.

Objective The function of regional myocardium of patients with myocardial infarction(MI) treated by intra-coronary stenting was determined with quantitative tissue velocity imaging(QTVI).Methods Twenty healthy controls and 24 patients with acute anterior myocardial infarction underwent QTVI with high-frame rates. The myocardial tissue velocity imaging in the apical 4-chamber view and apical 2-chamber view and apical longitude view were digitized and stored. Off-line ventricular walls regional velocity profiles along long axis were obtained, and systolic peak velocities (Vs) and early and late diastolic peak velocities (V E and V A) of 12 regional segments were measured.Results Under normal and ischemic conditions, 6 ventricular walls showed significant basal-apical myocardial velocity in the long-axis reduction in V S and V E and V A were significantly reduced in the abnormal segments in patients with MI. Conclusion QTVI can be used to analyze regional myocardial motion in the long-axis quantitatively and synchronously;intra-coronary stenting can obviously improve regional myocardial function of left ventricle,especially the diastolic function.

Objective To investigate the expression of Skp2 and Cx43 in cervical carcinoma and to study their relationships and clinical significance. Methods The expression of Skp2 and Cx43 was examined by immunohistochemical method in 48 cases of cervical carcinoma tissue, 84 cases of cervical intraepithelial neoplasia (CINⅠ - Ⅱ 45 cases, CINⅢ 39 cases), 28 cases of chronic cervicitis. Results Skp2 expression in cervical carcinoma was higher than that in the CINⅠ - Ⅱ and chronic cervicitis (P <0.05), Cx43 expression was lower in cervical carcinoma than that in the CINⅢ, CINⅠ - Ⅱ and chronic cervicitis (P <0.05). The expression of Skp2 was correlated with histological differentiation and lymph node metastasis (P <0.05). The expression of Cx43 was correlated with the lymph node metastasis (P <0.05). Besides, the expression of Skp2had a negative correlation with that of Cx43. Conclusion Skp2 and Cx43 may play an important role in the genesis and development of cervical carcinoma.

ObjectiveTo screen for proteins related to invasive and metastatic potential of ovarian cancer.MethodsThe nude mice were intraperitoneally injected with the human ovarian cancer 3AO cell line.The metastatic tumors were isolated and cultured in vitro.The cell lines were established from tumors and transplanted intraperitoneally for several passages.Invasive potential of cell lines was evaluated by cell adhesion and matrigel invasion assays.Lysates from different cell lines with high or low invasive potential were analyzed by surface enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS)and protein-chip array technology.The proteomic fingerprint patterns were compared. ResultsThe subclones 3AOF3 and 3AOF4 were isolated from repeated passaging in vivo and vitro,and showed higher invasive capacity than 3AO cells.By comparing their proteomic fingerprints,9 distinct proteins (3494,3831,8121,8293,9123,9332,10 184,15 436 and 17 134 at m/z value) were found,which were expressed only in 3AO cells.On the contrary,1 distinct protein (4360 at m/z value) was expressed only in 3AO F3-4 cells,and 2 distinct proteins (1842 and 3145 at m/z value) were expressed only in 3AO F2-4 cells.Additionally,6 distinct proteins (1236,5476,5649,6575,6897 and 7016 at m/z value) and a mass cluster (13 794 and 14 027 at m/z value)were expressed in all 3AO and 3AOF1-4 cells,while the amount of protein was different.ConclusionBy comparing the proteomic fingerprints of isogenic ovarian cancer cells with different invasive potential,a group of proteins are identified which are correlated with high invasive and metastatic potential.

Objective To study the role of coping styles in the relationship between coping resources and psychosomatic health in patients with asthma. Methods 184 adult patients with asthma were investigated with General Serf-Efficacy Scale (GSES), Internality, Powerful Others, and Chance Scale (IPC), Social Support Rat-ing Scale (SSRS), Defensive Style Questionnaire (DSQ), Trait Coping Style Questionnaire (TCSQ) and Short Form 36 Health Survey Questionnaire (SF-36). Results Significant correlation between self-efficacy (r=0.356),locus of control(Ir=0.208, Pr=0.341, Cr=-0.349) ,subjective(r=0.201) and objective(r=0.189)social support, immature and middle ( r = - 0. 257 ) defensive styles and coping styles ( PCr = 0.231, NCr =-0.505 ) with Mental Component Summary (MCS) was found (all P <0.05), but Physical Component Summary (PCS) was only related to self-efficacy( r=0. 175) ,chance(r=0.150),immature(r=-0.256) and middle de-fensive Styles and negtive coping styles (all P < 0.05). PCS (t = - 5.189) and MCS (t = - 6. 758) could be predic-ted effectively by negative coping style (all P<0.01). Moreover, self-efficacy, powerful others and the use of so-cial support could had an effect on the health of patients through negative coping style. Conclusion Negative coping style could not only have a direct effect on the health of asthma patients but also be a mediator between self-efficacy, locus of control, social support and the health of patients.
