Objective To investigate the status quo of returning to the society of middle-aged and young patients undergoing peritoneal dialysis based on the health empowerment theory. Methods Using the purposive sampling method, 11 patients were interviewed. The interview results were analyzed using Colaizzi analysis and the keywords were extracted. Result A total of 9 keywords were extracted, including beliefs and attitudes ( the sense of responsibility, economic burden and social needs to be met);knowledge and ability ( ability to maintain normal peritoneal dialysis but lack of the ability to solve related complications and decreased work ability after returning to society);related to action and performanc ( limited occupational self-development after returning to society,related to social support and resources:more social support, guidance in chronic disease management and proper social welfare). Conclusions Returning to society can improve the living conditions of middle-aged and youth patients with peritoneal dialysis although they can run into troubles in economic conditions, fatigue, and lack of disease management knowledge and ability. Medical workers should provide them with instructions on disease management knowledge, strengthen social support system other than their families and help them out of the troubles so that they can return to society and enhance their life of quality.

Objective: To explore the Influence of ethics education on ethical beliefs of dual relationship of trainees who attend training of psychological consultation.Methods: Use of questionnaire,written and directed by "psychological counseling and treatment of ethical issues questionnaire(trainee attending psychological consultation training)" as a tool to evaluate,within the framework of Guangdong 368 trainees to investigate.Results: Compared with two groups of trainees,in refer to the ethical beliefs of dual relationship,the latter group who has a higher option of "not sure" shows varying degrees of decline in most of the items in the questionnaire.Two teams of trainees reach an identity of 80% or more(10 items in total) in the ethical judgment of dual relationship(choose "not").Two groups show significant differences in judging 5 items of the entries(p

According to the overview of historical development of ethical research in psycho-counseling and psycho-therapy in developed countries,this paper aims to summarize the research experience and outcome,in order to promote related Chinese ethical research based on China's realistic situation.

A model of vascular smooth muscle cell proliferation was estabolished by balloon angioplas-ty in rat's aorta. We found that treatment with batroxobin decreased plasma fibrinogen level after angio-plasty, and inhibited the increase in smooth muscle cell count of injured vascular wall and incorporation rate of H-TdR into vascular tissues effectively. The results suggest that batroxobin may have clinically prospective significance in prevention and therapy of angioplasty-induced restenosis.

To put forward spatial resolution detection requirements of 64-slice helical CT based on analyzing the present situation of CT spatial resolution detection. The requirements for spatial resolution in the existing industrial standards were analyzed, and some test data were used to prove the deficiency of the standards. Spatial resolu-tion detection requirements were proposed for 64-slice helical CT, and the factors affecting spatial resolution were ex-plored. The deficiencies in the original standards were eliminated. The proposed requirements may facilitate the spatial resolution detection of 64-slice CT, and thus can enhance image quality for clinical diagnosis and treatment.

Objective To analyze of the relationship between level of anxiety and depression before surgery and anus exhausting time for patients after gynecological abdominal surgery.Methods A descriptive study was conducted with a survey of 100 cases of patients with gynecological abdominal surgery where the level of anxiety and depression before surgery and post-anus exhausting time were analyzed to explore the correlation between them.Results In the 88 valid questionnaires,the incidences of stress and anxiety before surgery were respectively 38.64％(34/84) and 19.32％(17/88) and the average anus exhausting time after surgery was (44.55 ± 13.90) hours;the anus exhausting time of anxious patients was significantly longer than that of non-anxious patients [(48.35±12.84) hours vs.(42.50±14.13) hours,t=-2.12,P＜0.05] and bivariate Logistic regression analysis suggested that preoperative level of anxiety had a significant effect on anus exhausting time after surgery.Conclusions Stress,anxiety and other negative emotions can affect anus exhausting time after surgery and level of anxiety could be used as one predictor of the delay of anus exhausting time after surgery.

Objective:To analyze the expression of E-cadherin in the epithelial-mesenchymal transition (EMT) induced by transforming growth factor-β1 (TGF-β1) in neuroblastoma.Methods:TGF-β1(1 μg/L, 5 μg/L, 10 μg/L), was applied to SK-N-SH cells in vitro compared with the blank control group.EMT-related genes mRNA and protein expression were detected by carrying out real-time PCR assays and Western blot.A scratch test and migration assay were performed to verify the alteration of SK-N-SH cell migration capacity.Data collected from 18 cases of neuroblastoma patients were selected from the Department of Hematology Oncology, Shanghai Children′s Hospital from January 2008 to December 2012.The expression of E-cadherin in the tumor tissue of the neuroblastoma patients after operation was detected by immunohistochemistry.The clinical features and survival prognosis of these patients were analyzed. Results:Compared with the control group, after SK-N-SH cells were treated with TGF-β1(1 μg/L, 5 μg/L, 10 μg/L), real-time PCR assays and Western blot revealed that the mRNA(0.603±0.081, 0.606±0.008, 0.716±0.166 vs.1.000) and protein expression levels(0.855±0.026, 0.600±0.017, 0.495±0.011 vs.1.000) of E-cadherin were significantly decreased ( F=8.144, P=0.040; F=74.810, P<0.001), while the mRNA(2.132±0.167, 3.494±0.017, 4.184±0.021 vs.1.000) and protein expression levels (1.175±0.053, 1.189±0.058, 1.225±0.106 vs.1.000)of α - smooth muscle actin were significantly increased ( F=547.300, P<0.001; F=68.810, P=0.007), suggesting that EMT changes occur in cells.Scratch test and Transwell migration assay revealed that the number of migrating cells increased obvious with the treatment of TGF-β1 (5 μg/L) ( t=16.070, P=0.040). The 10-year overall survival(OS) rates of neuroblastoma patients with E-cadherin strong positive expression, positive expression, weak positive expression and negative expression in the pathology were (77.78±13.86)%, (75.00±21.66)%, (25.00±21.65)% and 0, respectively ( F=8.160, P=0.040). Conclusions:TGF-β1 can induce the EMT in SK-N-SH cells and increase cell migration.The decrease expression of E-cadherin in neuroblastoma patients is closely associated with clinical progress and recurrence or metastasis of the disease.

Objective To determine the characteristics of retinal vascularization in premature infants. Methods A prospective study was carried out which included all premature infants with birth weight<2 000 g, who were hospitalized in Guangdong Women and Children's Hospital from September 1, 2009 to August 31, 2010. Close retinal screening and follow-up were carried out in order to record retinal vascularization at different post-conceptional ages. Spearman correlation analysis was performed for statistical analysis. Results A total of 231 infants were enrolled, and follow-up was completed in 212 infants giving a follow-up rate of 91.8%. Twenty-eight infants developed retinopathy of prematurity (ROP) resulting in a ROP morbidity of 13.2%, and 184 cases had full retinal vascularization. The median birth weight was 1 600 g (1 000-1 900 g) and the median gestational age was 32.4 weeks (27.0-35.5 weeks). In the 32-week post-conceptional age group, the proportion with full vascularization in ZoneⅠ,ⅡandⅢwas 87.1%(81/93), 7.5%(7/93) and 0.0%(0/93), respectively. In the 36-week post-conceptional age group, full vascularization was observed in ZoneⅠ, and the proportion with full vascularization in ZoneⅡandⅢrose sharply at 38-week and 40-week post-conceptional age, respectively. The proportion with full vascularization in ZoneⅢwas 100.0%(24/24) at 43-week post-conceptional age. According to Spearman correlation analysis, there was a positive correlation between ZoneⅡand Zone Ⅲ retinal vascularization progression and post-conceptional age (r=0.690 and 0.720;P=0.000). In premature infants, full retinal vascularization in ZoneⅠoccurred at 36-week post-conceptional age. The median gestational age for ZoneⅡand ZoneⅢretinal vascularization was 38 weeks (32.2-40.4 weeks) and 41 weeks (36.0-42.6 weeks), respectively. Therefore, a further 2-3 weeks were required for full retinal vascularization in ZoneⅡand ZoneⅢ. The time differences for under-vascularization in ZoneⅡandⅢwere 8 to 10 weeks, and the time differences for full vascularization in ZoneⅡandⅢwere 8 weeks and 6 weeks, respectively. Conclusion Retinal vascularization varies in premature infants. Almost all premature infants complete vascularization by term gestational age and the majority of infants need to be followed up to 41 weeks. It is essential to focus on the different retinal regions during maturation.

Objective To identify predictors of prescription initiation and persistence of warfarin in non-valvular atrial fibrillation ( NVAF ) patients with high risk of stroke ( CHA2 DS2-VASc≥2 ) . Methods NVAF patients consulted in our hospital from Aug , 2011 to Apr, 2015 were enrolled.Patients who underwent radiofrequency catheter ablation were excluded . Patients were divided into two groups (warfarin group and non-warfarin group).Logistic regression was used to estimate the predictors of initiation warfarin prescription.Kaplan-Meier survival and Cox proportional hazards model was performed to determine rate of warfarin persistence and its associated factors .Results A total of 622 AF patients were enrolled and 490 patients with CHA2DS2-VASc≥2.Ten patients lost follow up and 480 patients were followed up with a mean follow-up period of ( 40.0 ±11.55 ) months.Of which 245 NVAF patients ( 51%) had a warfarin prescription.Patients with ischemic stroke ( OR 2.447 , 95%CI 1.435-4.171 , P=0.001 ) , heart failure ( OR 2.009 , 95%CI 1.084-3.724 , P=0.027 ) and persistent AF ( OR 2.231 , 95%CI 1.448-3.437 , P=0.0001 ) had a higher likelihood of warfarin prescription .Anemia ( OR 0.479 , 95%CI 0.238-0.964 , P=0.039), concommitant Traditional Chinese Medicine (TCM) use (OR 0.638, 95%CI 0.456-0.891, P=0.008 ) and longer distance to hospital ( OR 0.759 , 95%CI 0.610-0.945 , P=0.014 ) decreased the likelihood of warfarin prescription . One hundred and seventy-six ( 71.8%) warfarin users continued persistent therapy and the overall proportion of warfarin persistence was 78.3% for one year , 71.0% for 3 years.Seventy-six existing warfarin users continued the warfarin therapy (80%, 76/95),one hundred new users showed persistence to therapy ( 66.7%, 100/150 ) .Warfarin use before enrollment significantly increased warfarin persistence than new prescription ( P =0.008 ) .Variables associated with higher discontinuation were new prescription ( HR 1.786 , 95% CI 1.029-3.100 , P=0.039 ) , TCM use ( HR 1.687 , 95%CI 1.201-2.37 , P=0.003 ) and longer distance to hospital ( HR 1.446 , 95% CI 1.121-1.865, P=0.005).Conclusions In anticoagulation clinic, concommitant TCM use, distance to hospital and other factors were associated with warfarin initiation prescription and persistence .Identifying factors associated with warfarin treatment could help in developing adherence of patients .
