Methods Professional self-concept of nurses instrument (PSCNI) scale was used to investigate the self evaluation of nursing students and nursing staff in the aspects of nursing skills, leadership, flexibility,satisfaction degree and communication skills. SPSS 19.0 was used to analyze the total scores and scores of each aspects; F test and t test were used to analyze the difference between two groups. Results Total score for nursing students and nursing staff were (81.27±7.40) points (67.7%) and (85.00±7.96) points (70.0%), with significant differences between the two groups (P=0.003). Scores in as-pects of nurturing skills, communication, flexibility were higher in nursing staff than in nursing students, with significant differences between the two groups (P<0.05). Conclusion The cognition and feeling of nursing staff is better than nursing students in aspects of nurturing skills, communication, flexibility. Nursing teaching can correspondingly improved based on the differences between the two groups.

Objective To explore the role of neutrophil extracellular traps (NETs)-induced endothelial cell damage in the pathogenesis of dermatomyositis (DM)-associated interstitial lung disease (ILD).Methods Serum free DNA and krebs von den lungen-6 (KL-6) level were tested in healthy controls,dermatomyositis patients with or without interstitial lung disease (DM-ILD and DM-NILD).Subjects' peripheral blood neutrophils were stimulated with phorbol 12-myristate 13-acetate (PMA),then human umbilical vein endothelial cells (HUVECs) were co-cultured with NETs.The cell morphology was observed by the inverted phase contrast microscope.Cell viability was detected by cell counting kit-8 (CCK8).Results The concentration of serum free DNA in DM patients [(271.27 ± 76.53) μg/L] was significantly higher than that in health control (HC) [(152.89 ± 37.34) μg/L,P ＜ 0.001].Moreover,free DNA level in DM-ILD patients [(302.67 ± 74.15) μg/L] was higher than that in DM-NILD patients [(235.59 ±63.55) μg/L,P ＜0.005].The concentration of KL-6in DM patients [(3.08 ±2.07) μg/L] was higher than that in HC [(0.87 ± 0.51) μg/L,P ＜ 0.001].Similarly,KL-6 in DM-ILD patients [(4.00 ± 2.44) μg/L] was higher than that of DM-NILD patients [(2.03 ± 0.61) μg/L,P ＜ 0.005].Free DNA and KL-6 were positively correlated (r =0.251,P ＜ 0.05).The survival of endothelial cells in DM group (53 ± 11) ％ was lower than that of HC group [(70 ± 5) ％,P ＜ 0.001].Not surprisingly,the survival of endothelial cells in DM-ILD group (44 ±4) ％ was lower than that in DM-NILD group [(61 ± 8) ％,P ＜ 0.01].Conclusion NETs could play an important role in the pathogenesis of dermatomyositis associated interstitial lung disease,suggesting that NETs may be the potential therapeutic target.

Posterior capsular opacification (PCO) is one of the major complications of modern cataract surgery.Multiple studies had demonstrated that the extracellular matrix (ECM) plays an important role in the generation and development of PCO.A variety of ECM components,including fibronectin (FN),laminin (LN),collagen,lumican,osteoponin (OPN),decorin,hyaluronic acid and vimentin,affect the biological properties of lens epithelial cells (LECs) through different mechanisms,such as regulating cell migration,adhesion and proliferation.This review focuses on the role of ECM in PCO formation in order to explore the pathogenesis of PCO and provide a potential therapeutic approach for the prevention and management of PCO.

Objective To investigate the clinical manifestations, endoscopic manifestations, histological characteristics, diagnosis and treatment of the primary gastrointestinal melanoma in China. Methods The gender, age, position, endoscopic manifestations, histological characteristics, treatment, prognosis of the primary gastrointestinal melanoma were gathered and analyzed by reviewing retrospectively the data of 2 cases seen at our hospital and 449 cases searched in CNKI from 1983 to 2015. Results The primary gastrointestinal melanoma was mostly seen in the rectum and anus, and secondly in the esophagus. A typical endoscopic finding was a protuberant or nodular tumor, with erosion or dirty surface on it. Most lesions were friable and easily hemorrhagic. The maximum diameters of most lesions, accounted for 83.3 %, were larger than 2.0 cm. The average value of the maximum diameters was (4.79 ± 2.67) cm. Most cases presented brown or black, followed by hoar. However, some lesions presented various colors, such as blue, red, even co-exited color or achromatic color. Preoperative misdiagnosed rate was 73.64 % and 1-year mortality was 54.19 %. Negative correlation was observed between survival time and lesion size, infiltration depth. Positive correlation was observed between lesion size and metastasis infiltration depth. Survival time had nothing to do with metastasis and age. Conclusion The primary gastrointestinal melanoma was highly aggressive, and usually found in the terminal age, usually together with extensive metastasis, misdiagnosed and poor prognosis. Knowing the clinical features, endoscopic manifestations, histological and immunohistochemical characteristics is the key to early diagnosis.
