Objective To explore the impact of psychological alignment and coping style on nurse′s job satisfaction. Methods A total of 389 clinical nurses were investigated by the Sense of Coherence Scale, the simplified Coping Style Questionnaire and Minnesota Satisfaction Scale. Results The scores of job satisfaction, psychological alignment, positive coping and pessimistic coping of clinical nurses was (72.91 ± 11.10), (56.97 ± 10.29), (23.16 ± 5.40) and (9.80 ± 4.03) points respectively. The predictors of job satisfaction were sense of control, sense of meaning and positive coping style. Conclusions It is suggested that nursing managers should pay close attention to nurses′psychological alignment and guide clinical nurses adopt positive coping style, and thereby to improve nurses′job satisfaction.

Objective:To investigate the relationship between surface hydrogen form and the bioactivity of titanium.Methods:Sandblast titanium was etched with the combination of sulfuric and hydrochloric acids(SLA group,n=3 ).Then etched titanium was heat at 450 ℃in air(SLA+HT group,n=3).Surface topography,roughness,hydrophility,surface chemical texture were observed. Finally,the titanium samples were soaked in body simulate fluid for 3 days,the mineral deposition properties were observed by X-ray diffraction.Results:Titanium hydride was formed on the titanium surface after etching.After heat treatment,surface texture and roughness were not changed,titanium hydride decomposed and hydrophility increased.More hydroxyapatite was found on the surface of the samples treated by SLA+HT and followed by SBF.Conclusion:Titanium hydride can not improve the bioactivity of titanium, heat treatment may increase the mineralization.

Objective:To explore correlation between RoSCo score and postoperative absolute bed rest time in patients undergoing laparoscopic partial nephrectomy (LPN) .Methods:The imaging data and clinical data of patients undergoing LPN from January 2018 to July 2019 in a Class ⅢGrade A hospital in Suzhou were retrospectively analyzed. RoSCo score was calculated by RENAL score, body mass index (BMI) and Charlson comorbidity index. According to the score, patients were divided into low-risk group (RoSCo score≤4 points) , medium-risk group (RoSCo score of 5 to 6 points) , high-risk group (RoSCo score≥7 points) , and postoperative absolute bed rest time of patients in three groups were collected. The kruskal-Wallis H test of non-parametric test was used to compare the absolute bed rest time of patients in the three groups, and Spearman correlation method was used to analyze the correlation between RoSCo score and postoperative absolute bed rest time. Results:A total of 164 LPN patients were included in the study, including 82 cases in the low-risk group, 65 cases in the medium-risk group and 17 cases in the high-risk group. The median and quartile of absolute bed rest time of all patients was 7 (6, 8) d, including 6 (5, 6) d in the low-risk group, 8 (7, 8) d in the medium-risk group and 11 (11, 12) d in the high-risk group. Postoperative absolute bed rest time of low-risk group, medium-risk group and high-risk group classified by RoSCo score were different, and the differences were statistically significant ( H=112.9, P<0.001) . The pairwise test after using Bonferroni method to correct the significance level found that pairwise comparison of the three groups showed statistically significant differences (all adjusted P<0.001) . RoSCo score was positively correlated with postoperative absolute bed rest time ( r=0.815, P<0.001) . Conclusions:RoSCo score of patients undergoing LPN has a significant positive correlation with postoperative absolute bed rest time. The higher the RoSCo score is, the longer the absolute bed rest time is. Therefore, nursing staff can predict the postoperative absolute bed rest time of LPN patients based on RoSCo score so as to provide a basis for clinical nursing decision.

Background:Inflammatory bowel disease (IBD)is a group of chronic gastrointestinal inflammatory disease and its diagnosis depends on analysis of clinical,endoscopic and pathological characteristics. Aims:To analyze the clinical, endoscopic and pathological characteristics of IBD. Methods:Clinical,endoscopic and pathological characteristics of 99 patients with IBD [including 61 ulcerative colitis (UC)and 38 Crohn's disease (CD)]from January 2010 to April 2017 at Yijishan Hospital were retrospectively analyzed. Results:Compared with CD patients,age in UC patients was significantly increased,incidences of diarrhea,bloody stool were significantly increased while incidence of abdominal mass was significantly decreased (P < 0. 05). Extensive type UC and ileocolonic type CD were common. Proportion of patients received 5-aminosalicylic acid (5-ASA)was significantly higher in UC than in CD (90. 2% vs. 71. 1%,P = 0. 014). Two UC patients achieved remission shown by endoscopy,and endoscopic remission achieved in 3 CD patients. The main pathological features of UC were cryptic branching (57. 1%),cryptic twisting (76. 2%),cryptic atrophy (54. 8%)and cryptic irregularity (28. 6%). Ulcer was seen in 78. 9% of CD patients with active chronic inflammation (mainly lymphocyte and plasmocyte infiltration),and the detection rate of non-caseating granuloma was 15. 8% . Conclusions:UC patients are characterized with older age,diarrhea,bloody stool and higher administration rate of 5-ASA,and the endoscopic features were mucosal bleeding and ulcers. Pathological characteristics of UC were mainly cryptic architectural change and inflammatory infiltration,while those of CD were mainly segmental lesions and chronic inflammation with lymphocyte and plasmocyte infiltration and some with non-caseating granuloma.
