Objective To describe the status of nurses′professional identity and the self-concept and to explore the relationship between nurses′professional identity and the self-concept. This will be the base for intervening nurses′professional identity. Methods A convenience sample of 250 nurses from one major hospital in Beijing was recruited. The Macleod Clark Professional Identity Scale and the Professional Self-Concept Instrument were introduced. A standard translation procedure was carried out. Results A total of 250 questionnaires were sent out, 241 questionnaires were withdrawed with an effective rate of 96.4%. The mean score of nurses′professional identity was 42.54±8.70, which was at moderate level. The mean score of nurses′professional self-concept was 86.28 ±22.86, also at moderate level, among which,knowledgescores highest (25.91±6.00), leadership scored 20.84±8.02, inter-personal relationship scored (20.28±4.18), caring scored the lowest (19.25±4.67). There was significant difference among the professional identity in the different departments (P<0.05) , while the same results were not seen in professional self-concept. Nurses′professional identity was positively correlated with professional self-concept′s four dimensions (P<0.05). Conclusions The nurse managers should pay attention to the cultivation of professional self-concept in the training of nurses in order to improve the professional identity of nurses and the whole nurses′development.

Objective To investigate the efficacy and safety of endoscopic submucosal dissection (ESD) for removal of gastrointestinal stromal tumors (GISTs). Methods Data of 22 patients with GISTs,who underwent ESD, were reviewed in terms of personal situation, location and size of lesions, clinical manifestation, managements, pathology, complications and follow-up findings. Results The procedure was successfully performed in all patients and all lesions were removed by one procedure. The lesion size ranged from 0. 8 to 4. 0 cm and the operation time was 35-150 min ( mean 64. 5 min). Mild bleeding occurred in all cases, which was successfully managed by argon plasma coagulation, hot biopsy probe or endoclip. Perforation occurred in 4 patients (18. 1%), which were closed with endoclip. Abdominal distension was relieved with decompression, acid suppression with proton pump inhibitors and antibiotics in 3 cases, additional trans-abdominal puncture was needed in the other case. No severe hemorrhage occurred. The average length of hospitalization was 4. 5 days (3-10 d). The patients were followed up for 3 to 18 months, and no tumor residue or recurrence was observed. Conclusion ESD is an effective and safe endoscopic procedure to remove GISTs. The main complications are bleeding and perforation, which, however, can be cured.
