Objective To prepare and identify monoclonal antibody against LRR-WSC domain of polycystin-1 and to investigate the distribution of polycystin-1 in kidney tissues and kidney cell lines. Methods BALB/c mice were immunized with fusion protein PC1-e of polycystin-1 LRR-WSC domain. The splenocytes were fused with myeloma cells by PEG 4000 and the hybridomas were selected in HAT medium. The hybridoma clones secreting antibodies against polycystin-1 LRR-WSC domain were detected by enzyme-linked immunosorbent assay ( ELISA) and cloned by limiting dilution. The specificity of anti-polycystin-1 LRR-WSC domain monoclonal antibody from hybridoma was verified by ELISA and Western blot. The distribution of polycystin-1 in tissues and cells was detected by immunohistochemical method. Results One cell line of hybridoma secreting monoclonal antibody against polycystin-1 was established. Western blot analysis showed that the monoclonal antibody reacted strongly and specifically to polycystin-1 LRR-WSC domain. Distribution of polycystin-1 in fetal kidney was localized in tubular epithelium. In normal adult kidney tissues, our study showed that polycystin-1 was mainly expressed in the medullary collecting ducts and distal convoluted tubules. Positive staining was also found in the majority of cyst-lining epithelial ceEs of cystic tissue from autosomal dominant polycystic kidney disease ( ADPKD) patients. Expressions of polycystin-1 were found in either ADPKD cyst-lining epithelia cell line and LLC-PK1, clearly plasma membrane and intracytoplasmic staining of polycystin-1 were observed. Conclusion Specific monoclonal antibody against polycystin-1 LRR-WSC domain were obtained. The antibody is important to researching the mechanism of ADPKD. The distribution of polycystin-1 in kidney tissues and cells show that polycystin-1 was important in tubular elongation and the maintenance of tubular architecture.

The practice of general practice emphasizes that the general practitioner is the backbone, and the primary health institution is the main body, which solves the main health problems of the commu-nity and meets the basic health service needs of the residents. Rehabilitation medicine occupies a prominent position in the community health service, and its related knowledge and skills are the important part of the whole medical education. However, rehabilitation medicine has more teaching contents, less training time and out-of-date teaching model, which have made the effect of rehabilitation medicine teaching not good. In the rehabilitation medicine teaching for training general practitioners, by strengthening the concept of reha-bilitation, elaborating teaching content, optimizing teaching ward-round, and outstanding ability as well as reforming evaluation way, we try to exercise the students' clinical thinking and improve clinical skills, to cultivate outstanding qualified general medical practitioners for community rehabilitation ultimately.

Objective To investigate the current status of psychological capital, career plateau and turnover intention in ICU nurses and to analyze the influence of psychological capital and career on turnover intention. Methods A total of 233 ICU nurses from the 2nd Affiliated Hospital of Wenzhou Medical University who met the criteria were selected by convenient sampling from February to April 2017. The nurses were investigated with the Psychological Capital Questionnaire-Chinese (PCQC), Career Plateau Questionnaire (CPQ) and Turnover Intention Scule (TIS). Totally 233 questionnaires were handed out and 224 valid questionnaires were collected. Results The total score of psychological capital in the 224 ICU nurses was (88.53±13.16), and the highest score was found in the dimension of self-efficacy, while the lowest score was in the dimension of hope; the total average score of career plateau was (3.83±0.92); and the score of turnover intention was (16.82±5.01). According to the hierarchical stepwise regression analysis, contractual employment, hope, hierarchical plateau and content plateau were the main influencing factors of ICU nurses' turnover intention, which could account for 39.8% of the total variation. Conclusions ICU nurses show a strong turnover intention, and contractual employment, hope, hierarchical plateau and content plateau may affect their turnover intention. ICU nursing managers should formulate proper and effective improvement strategies for psychological capital and alleviation strategies for career plateau based on the current status of psychological capital and career plateau in nurses and take proper measures to enhance their enthusiasm and job satisfaction of contractually employed nurses, and reinforce the stability of ICU nursing team.
