Objective To understand the feelings and experiences of nurses in family medical team in the process of implementing contracted services,in order to provide a reference for effectively exerting the function of nursing in contracted services,and promoting and optimizing the contracted services in China.Methods Using phenomenological research methods,14 team nurses from 3 community health service centers in Beijing were interviewed with semi-structured interviews.The content analysis method was used to analyze the data.Results 3 themes were extracted in the nurses'experiences and feelings during the implementation of the contracted services,personal growth and benefit,and the need to optimize the work.3 sub-themes were extracted in work experiences and feelings,namely sense of optimization of nursing philosophy,sense of changing focus of nursing,improvement of nurse and patient bond.4 sub-themes were extracted in personal growth and benefits,namely increasing job responsibility and accomplishment,forming a sense of teamwork,greater understanding and respecting for patients.5 sub-themes were extracted in the optimization of contracted service needs,namely clarifying the position of team nurses,improving the bidirectional referrals,improving the contracted team management and assessment mechanisms,strengthening the support of the policy on home care,and providing opportunities for continuing education and training.Conclusion In practicing contracted services,team nurses have gained recognition of their profession and continuous self-growth.The government should continue to improve the support of contracting-related policies to meet the needs of team nurses'career development,optimize contracted services,and attract more nurses into the practice of contracted services.

Objective To measure the level of platelet derived growth factor-BB (PDGF-BB) in maintenance hemodialysis patients and investigate the significance of carotid atherosclerosis.Methods Thirty-six maintenance hemodialysis patients (test group) and 20 healthy controls (normal control group) were enrolled in this study.The level of PDGF-BB was measured by enzyme-linked immunosorbent assay in two groups.Intima-media thickness (IMT) and atherosclerotic plaques of the extracranial common carotid artery were measured by echocardiography.Results The level of IMT and the positive rate of carotid atherosclerosis in test group were significantly higher than those in normal control group [(1991.8 ± 228.6) μ mol/L vs.(71.2± 15.9) μmol/L,(36.78 ±3.40) g/Lvs.(41.96±2.07) g/L,(4.97 ±0.57) mmol/Lvs.(4.48 ±0.84) mmol/L][(1.01 ±0.23) mm vs.(0.72 ±0.15) mm,69.4％(25/36) vs.10.0％(2/20)](P＜ 0.01).The level of plasma creatinine,albumin and total cholesterol in test group were significantly higher than those in normal control group (P ＜ 0.01 or ＜ 0.05).The level of PDGF-BB in test group was significantly higher than that in normal control group[(93.27 ± 31.58) ng/L vs.(31.71 ± 15.78) ng/L,P ＜ 0.01].In test group,age and the level of PDGF-BB and triacylglycerol in carotid atherosclerosis patients were significantly higher than those in non-carotid atherosclerosis patients [(48.04 ± 9.97) years vs.(34.54 ± 10.35) years,(102.60 ± 32.87) ng/L vs.(72.06 ± 13.67) ng/L,(1.51 ± 0.59) mmol/L vs.(1.01 ± 0.27) mmol/L] (P ＜ 0.01).Regression analysis showed that age (β =0.346,P ＜ 0.01) and PDGF-BB (β =0.594,P＜ 0.01) were the important impacting factors for IMT.Conclusion The level of PDGF-BB is increased in maintenance hemodialysis patients,and it may play an important role in carotid atherosclerosis.
