Objective To reconstruct anatomical structures and establish visible model of the hand and evaluate some key techniques of digitized virtual hand. Methods Three hands were scan and then perfused by self-curing denture acylic and cinnabar. With the datum from CT-scan of the specimen of perfused hand (cryopreserved 4-24 h), such anatomical structures as contour, bone, artery, extensor tendon, flexor tendon and nerve of hand were constructed by software of Mimics 10.01 and measured. Results The visible hand model based on anatomical structures was established and main anatomical structures were exactly showed. Each structure was displayed by the multiform solitude or combination. Vessel lumens was displayed hollow and fidelity. The hand nerve can the part demonstrate that can earnest reflect the normal human body nerve contour anatomy characteristic. Conclusion The visible hand model can provide 3D morphological data for clinical practice and research, as well as provide digitized model for virtual reality.

Objective This study aims to conduct an evidence-based analysis of the research progress and management status of the competence of clinical department heads and nurse managers in China,providing reliable references for further devel-oping their management research and improving the human resource management in Chinese hospitals.Methods The VIP,CNKI,WANFANG Chinese databases,online resources,and relevant official websites were searched to retrieve literature related to the competence of clinical department directors and nurse managers in China.Descriptive analysis was conducted using biblio-metrics and evidence-based principles and methods.Results A total of 82 articles were included,mainly focusing on the con-ceptual theories of clinical department directors and nurse managers,the construction of competence models,and application re-search.The research on the competence of clinical department directors and nurse managers in China started relatively late and showed a trend of initial growth followed by decline.The distribution of journals was relatively scattered,and the literature mainly came from higher education institutions and medical institutions.The research development has stagnated at the stage of empirical research and has not progressed to the stage of evaluative research.Conclusion The research on the competence of clinical de-partment directors and nurse managers in China is still in the stage of application and practice,lacking systematic research.It is mainly led by higher education institutions and medical institutions,and the attention from the national government in terms of competence of clinical department directors and nurse managers in hospitals needs to be strengthened.

Objective To analyze the impact of feedforward control nursing intervention on emergence agitation and recovery quality in general anesthesia surgery patients. Methods A total of 118 patients undergoing general anesthesia surgery were selected by convenient sampling, and randomly divided into control group and observation group, with 59 patients in each group. The control group received routine nursing intervention during emergence anesthesia, while the observation group received feedforward control nursing intervention. The incidence of emergence agitation, recovery quality, pain condition, and nursing quality were compared between the two groups. Results The incidence of emergence agitation during emergence in the observation group was significantly lower than that in the control group (42.37% versus 69.49%, P < 0.05). The Richmond Agitation-Sedation Scale (RASS) scores, duration and frequency of agitation were lower or shorter in the observation group than those in the control group (P < 0.05). The observation group exhibited shorter time for spontaneous respiration recovery, eye opening, extubation, full consciousness, and stay in the postanesthesia care unit compared to the control group(P < 0.05). The Steward emergence score was higher in the observation group (P < 0.05). The postoperative pain score was lower, while nursing quality score was higher in the observation group than those in the control group(P < 0.05). Conclusion Feedforward control nursing intervention can reduce the incidence of emergence agitation in general anesthesia surgery patients, improve recovery quality, alleviate postoperative pain, and enhance nursing quality.

Objective To study the cytomorphologic features of anaplastic lymphoma kinase ( ALK )-rearranged pulmonary adenocarcinoma.Methods The morphologic features in 153 pulmonary adenocarcinoma cytology specimens encountered during the period from September, 2011 to April, 2015 in Shanghai Cancer Hospital were retrospectively reviewed.Fluorescence in-situ hybridization ( FISH) and/or immunohistochemistry ( Ventana D5F3) for ALK gene rearrangement were carried out.The samples studied included 34 pleural effusion specimens, 40 endobronchial ultrasound-guided transbronchial needle aspirates ( EBUS-TBNA) and 79 fine needle aspirates of palpable masses on body surface.Results Thirty-nine cases (25.5%) of ALK-rearranged samples were identified by FISH and/or immunohistochemistry, including 3 cases diagnosed by FISH and 36 cases by both technologies.The median age of the ALK-positive group was 50 years, significantly younger than that of the ALK-negative group (60 years old,P=0.002) .Only 4 of the ALK-positive patients were smokers, which was significantly less than that of the ALK-negative group (P<0.01).In ALK-positive group, 3 cases showed cribriform pattern with prominent nucleoli, 3 cases showed cribriform pattern with mucin-rich cells and 8 cases showed extracellular mucus with mucin-rich cells.The above cytomorphologic patterns were significantly less common in ALK-negative tumors ( P <0.01 ) . Conclusions ALK-rearranged lung adenocarcinoma is associated with certain distinctive morphologic patterns, including cribriform architecture, presence of prominent nucleoli, mucin-rich cells and extracellular mucus, which can be observed in cytology specimens ( including conventional smears and cell block sections) .These findings, when combined with clinical features, may give clues to detection of ALK-positive cases.
