Objective To investigate the charge nurses' leadership style perceived by nurses and nurse's self-efficacy,and then analyze the relationship between them.Methods Totally 368 staff nurses from 3A hospitals in Sichuan were investigated with questionnaires.The results underwent analysis.Results The score of charge nurses' transformational leadership style was 58.06±12.10,from high to low in turn was intellectual stimulation (3.10±0.69),inspirational motivation (2.92±0.73),idealized influence (2.88±0.67) and individualized consideration (2.71±0.74).The score of charge nurses' transactional leadership style was 35.77±8.58,from high to low in turn was contingency reward (3.11±0.71),passive exemplary management (3.09±0.75) and active exemplary management (2.75±0.90).The score of nurses' self-efficacy was 83.51±11.62.The transformational leadership style had positively predictive impact on nurses' selfefficacy.Conclusions Nursing managers should apply transformational leadership to improve nurses selfefficacy,promote the physical and mental health of nurses and the long-term development of hospital.

Objective To study the etiology and clinics as well as CT diagnostic value of periventricular leukomalacia(PVL)in children.Methods Clinical and CT findings in 130 cases of PVL were retrospectively analyzed.Results 85 cases were premature newborn babies(65.4%) and 45 cases were fullmature newborn(34.6%) with hypoxic ischemic encephalopathy.CT showed the lateralventricle enlarge in different degrees and the white matter of periventricle decreased.Conclusion CT scan is of important value indiagnosis of PVL.

AIM To study the effects of recombinant human IL 1 receptor antagonist (IL 1ra) on isolated airway smooth muscle tissue. METHODS Changes of isolated organ's tension were monitored with force displacement transducer and MedLab recording system. RESULTS ①IL 1ra haddirect relaxant effect in normal and ovalbumin sensitized pulmonary as well as tracheal smooth muscle. The mean EC 50 values were 1 29?10 -8 mol?L -1 and 8 06?10 -8 mol?L -1 in normal pulmonary and tracheal smooth muscle, but the mean EC 50 values were 2 61?10 -7 mol?L -1 and 5 88?10 -7 mol?L -1 in ovalbumin sensitized pulmonary and tracheal smooth muscle. Therefore the relaxation responses of sensitized airway smooth muscle to IL 1ra were lower than those of normal pulmonary and tracheal smooth muscle.②IL 1ra(10 -9 ～10 -5 mol?L -1 ) concentration dependently inhibit contraction responses to histamine(10 -3 mol?L -1 ) in normal pulmonary and tracheal smooth muscle, compared with administrating solvent PBS group ( P

The mucosa associated lymphoid tissue(MALT) lymphoma represents a distinct subgroup of B cell non Hodgkin lymphomas (NHL) arising from extranodal sites. These neoplasms usually arise from the gastrointestinal tract,salivary gland,thyroid and ocular adnexal, which have been recognized from clinical,pathological and molecular genetics aspects.In this paper we reviewed the investigation progress of MALT lymphoma molecular biology.

300mg%). Conclusion: Acetylshikonin's content was high, radix arnebiae oil colour was very red, It was up to the mustard.

Objective To evaluate the effects of laparoscopic filling with pedicled greater retina for hepatic cysts. Methods Clinical data were reviewed on 36 patients with hepatic cysts undergoing laparoscopic filling with pedicled greater retina from January 2010 to May 2014.The diameters of cysts ranged from 10 to 26 cm, with a diameter smaller than 20 cm in 29 patients and bigger than 20 cm in 7 patients.Laparoscopic fenestration of hepatic cysts was performed to destroy cyst cells with iodine and absolute alcohol. Pedicled greater retina was used for filling the cavity of cysts. Results The procedures were completed smoothly.The operative time was 45-115 min, with an average of (80.4 ±13.1) min.No abdominal cavity infection happened.Primary healing of abdominal incision was achieved in all the patients.The postoperative hospital stay was 5-10 d, with an average of (6.4 ±1.2) d.All the 36 patients were followed up for 6-12 months with a mean of (9.3 ±1.5) months.None of the patients showed recurrence under liver B-ultrasonography or CT scanning. Conclusion Laparoscopic filling with pedicled greater retina for hepatic cysts has advantages of minimal invasion, quick postoperative recovery, short hospital stay, and good results.

Objective To analyze the trend of nursing information system(Nursing Information System,NIS) and contemporary situation,so as to provide a reference for the further development of NIS in China.Methods Based on China Academic Journal Network Publishing Database,Wanfang database and VIP Chinese academic periodical database,retrieval published NIS literature from 2009 to 2013 in China.Seven aspects were analyzed:time,areal distribution,cooperative rate,authors,institutions,periodicals and keywords.Results There were 438 articles from 128 published journals,47.9％ papers were in the statistical source journals.Research content mainly involved clinical nursing and nursing management.Conclusions NIS research has achieved great development in the past 5 years,but the researches should be strengthened in breadth and depth.

Objective To understand status quo of the domestic and foreign iceberg competency model application,and to provide basis for further study in the nursing iceberg competency model.Methods A literature review about the application of competency iceberg model at home and abroad since 2009 was carried out,the relevant data was listed,and the research situation of domestic and foreign nursing iceberg competency model was summarized.Results According to the 141 total literatures whose theme was the iceberg competency model,only 3 articles were related to the nursing field,while most of the iceberg competency model aimed at the study of enterprises in the high-level management personnel,sales personnel and so on.More researches on competency iceberg model were conducted abroad,involved in all walks of life,an research direction of nursing had turned from general iceberg competency model to the study of specific posts.Conclusions The iceberg competency model applied to the management of nursing human resources in China is developed lately and the studies lack breadth,depth and scientificalness.Compared with foreign countries,there is a big gap.A thorough iceberg competency model for human resource management is ought to be studied to provide a new perspective and a more useful tool for the early Chinese nursing theory and practice.

BACKGROUND: Trigeminal ganglion percutaneous puncture is one of the methods for the therapy of primary trigeminal neuralgia. The difficulties in percutaneous puncture technique and operation can lead accidental injury and some serious complications. The application of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia has the features of high accuracy in puncture and low complications, which can reduce the chances of accidental injury to surrounding vessels and nerves.OBJECTIVE: To evaluate the therapeutic effects of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia.DESIGN: A before-and-after experimental study based on patients.SETTING: Department of cerebral surgery of a municipal hospital of tradi tional Chinese medicine and a municipal hospital.PARTICIPANTS: Ninety patients including 39 male and 51 female patients with primary trigeminal neuralgia aged between 21 and 90 years old were selected from outpatient or inpatient department of Foshan Hospital of Traditional Chinese Medicine between 2001 and 2003.INTERVENTIONS: Glycerine was injected into trigerminal ganglion of each patient through percutaneous puncture under the guidance of DZY-C trigeminal nerve stereoguide. Therapeutic effects were evaluated by visual analogue scale(VAS) before and 30 minutes after the treatment.MAIN OUTCOME MEASURES: Results of therapeutic effects.RESULTS: Ninety patients with primary trigeminal neuralgia received trigeminal ganglion puncture with the application of DZY-C trigeminal nerve stereoguide. All punctures succeeded with one shot. After the injection of glycerine, the original trigeminal neuralgia disappeared in all 90 cases with the good and excellent rate of 100%.CONCLUSION: Trigeminal nerve stereoguide(DZY-C model) has the features of reasonable structural design, easy surgical operation, agile adjustment, less tissue injury, and safe manipulation, which can significantly eliminate trigeminal neuralgia.
