?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.

Objective To explore the impact of burden,positive feelings,coping style and social support on caregivers' fatigue of dementia patients.Methods 190 caregivers of dementia patients were investigated by using the questionnaires of Caregivers Burden Inventory(CBI),Positive Aspects of Caregiving(PAC),Simplified Coping Style Questionnaire (SCSQ),Social Support Rating Scale (SSRS) and Fatigue Scale-14 (FS-14).Results The caregivers' fatigue of dementia patients was positively correlated with burden(r=0.56,P＜0.01),negative coping style(r=0.31,P ＜0.01),and negatively associated with positive feelings(r=-0.33,P ＜0.01),social support (r =-0.36,P ＜ 0.01) and positive coping style (r---0.55,P ＜ 0.01),respectively.Path analysis showed coping style and social support had direct impacts on fatigue; burden had a direct impact on fatigue,and also had an indirect influence on it through coping style or social support; fatigue might be decreased by positive feelings and increased by negative coping style.Conclusion To prevent and relieve the caregivers'fatigue of dementia patients,caregivers should be encouraged to take positive coping style and increase social support so as to reduce burden and increase positive feelings.

Objective To investigate the effects of tirofiban combined with nitroprusside injection through the rapid exchange balloon catheter with self-made side holes on no-reflow (NR)phenomenon during elective percutaneous coronary intervention (PCI).Methods A total of 49 patients with NR phenomenon were randomly divided into the balloon catheter group (n=25)and the guiding catheter group (n=24).Tirofiban combined with nitroprusside were used in both groups.Thrombolysis in myocardial infarction (TIMI)grade and corrected TIMI frame count (CTFC)of target coronary artery at 10 minutes after administration were assessed.Results At 10 minutes after drugs injection,there were 21 (84.0%)patients with target of coronary TIMI 3 grade in the balloon catheter group,and 13 (54.2%)patients in the guiding catheter group.The CTFC was (33.5±12.5)frame in the balloon catheter group,and (41.9±1 5.3)frame in the guiding catheter group.The difference in TIMI and CTFC between the two groups was significantly (P <0.05).Conclusion Injection tirofiban combined with nitroprusside through the rapid exchange balloon cathe-ter with self-made side holes in NR patients during elective PCI might be feasible and effective.

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

The strategy for relocation of computer center room in hospital is expatiated.A set of measures are adopted such as careful planning,detailed design,aborative preparation,reasonable technique strategies,etc.The corresponding management system is established and.Finally,the computer center room is successfully relocated in one time without interruption of hospital information system.

Objective To assess the agreement of different endoscopy grading or scoring systems for inflammatory bowel diseases(IBD)including ulcerative colitis(UC)and Crohn's disease(CD).Methods A standardized table was prepared based on the searches for endoscopic grading or scoring systems on Medline and Chinese Biomedical Database,the data of 80 patients with UC and 31 with CD.who underwent colonoscopy in Shanghai Renji hospital from June 2006 to February 2007,were evaluated with each system by two physicians independently.Data were analyzed with SPSS 13.0.Results Six endoscopic grading and scoring systems of UC and three of CD were included for evaluation.For the systems of UC and CD,Kendall's coefficients of concordance were 0.71(P<0.01)and 0.34(P<0.01),respectively.There was no significant differenee between every two systems for UC.Nonetheless.Spearman's correlation coefficient between Chinese Grading System of Crohn's Disease(CGSCD)and Crohn's Disease Endoscopic Index of Severity(CDEIS)was 0.32(P=0.08).Significant differences in frequencies were detected in endoscopic systems for UC by Kruskal Wallis test(P<0.01).Conclusion There is satisfactory concordance among the endoscopic grading and scoring systems of UC,while CGSCD needs further improvement.Furthermore,Jeroen elassifieation inclines to severe category,while modified Baron scale tends to be a mild one.

Objective: To study the relativity between color and chemical composition in fruits of Schisandra chinensis by fruits' surface color value (L*, a*, and b*) and contents of active ingredients of fructus core S. chinensis). Methods: The surface chromatic value (multivariate linear regression equation of L*, a*, b* values and deoxyschizandrin, schizandrin B, schizandrol A, schinsantherin A) was established by SPSS 20.0 with mathematical statistics method, then the influence degree of the active ingredients of. S. chinensis was detected by F test. Results: The value of L* were significant negative with deoxyschizandrin (r ≥ 0.5), and other chromaticity values were very low or low-grade correlated with lignans Conclusion: The effective ingredient content of fruit of S. chinensis can be estimated by its chromatic values, and also can be used in the hierarchies of the fruit of S. chinensis, in order to provide better scientific basis of the quality of S. chinensis.
