Objective To assess the efficacy of the laryngeal mask airway i-gel (LMA i-gel) in patients undergoing neuro-interventional surgery. Methods Forty ASA Ⅰ or Ⅱ patients of both sexes, aged 20-60 yr,body mass index ＜ 30 kg/m2, undergoing elective neuro-interventional surgery, were randomized into 2 groups (n = 20 each):LMA i-gel group (group I) and LMA ProSeal group (group P). After induction of anesthesia with TCI of propofol and remifentanil, LMA i-gel and LMA ProSeal were inserted in group I and P respectively. The patients were mechanically ventilated and PETCO2 was maintented at 35-40 mm Hg,SpO2 at 99%-100%. BP and HR were monitored and recorded before induction, immediately after induction, at 1, 3 and 5 min after insertion of LMA and immediately after removal of LMA. The success rate, LMA placement time, leak pressure, peak airway pressure and complications were recorded. Results There was no significant difference in the success rate, the LMA platcement time and peak airway pressure between the two groups (P ＞ 0.05). BP and HR were within the normal range during operation in both groups. The leak pressure and incidence of blood stain and sore throat were significantly lower in group I than in group P (P ＜ 0.05). Conclusion LMA i-gel can provide adequate ventilation during operation with less complications and can be used effectively for neuro-interventional surgery.

Objective To survey the status of the clinical competence and meta-cognitive ability of college nursing students, to explore the correlation between the two factors, and analyze the influencing factors of baccalaureate nursing students′ clinical skills, then explore the approach of improving the clinical competence of nursing students. Methods Totally 184 nursing students from Taishan Medical University were investigated by General Information Questionnaire, Clinical Competence Test Scale, University Students Meta Cognitive Ability Scale. Results Nursing students′ average score of meta cognition was 80.48 ± 11.97, the average score of clinical competence was 121.22 ± 22.74. The meta cognitive ability and clinical competence of nursing undergraduate students both maintained at the middle level. Meta cognitive ability was positively correlated with clinical competence. To some extent, enhancing the meta cognitive ability could help students improve the clinical competence. Conclusions To understand the status and correlation between meta cognitive ability and clinical competence can guide students to learn effectively, can help teachers play a good role in teaching effectively.

Objective To use three different methods-different nursing level,different ADL and nursing manhour to allocate nursing human resources,and find their difference.Methods Using observation method to record nursing time,and then using three different methods to allocate nursing human resources.Results 22 persons were needed using nursing level to allocate,20 persons were needed using ADL method and 15 persons were needed using nursing manhour to allocate nurses.The difference of direct nursing time between patients with primary care and secondary care had statistically significant difference.The difference of direct nursing time between patients with different ADL had statistically significant difference.Conclusions It is different using three methods to allocate nursing human resources.How to select a suitable method to accurately calculate nursing human resources and combine computer and the present methods is the problem which we should solve currently.

Objective To investigate the imaging findings of primary bone malignant fibrous histiocytoma (PBMFH) in long bone. Methods MRI and XV ray examinations were performed in 10 patients with PBMFH in long bone confirmed by histology. CT scans were performed in 6 cases. Results Nine cases had single and 1 case had multiple lesions of single bone. Seven cases showed osteolytic bone destruction, and 3 cases showed mixed bone destruction. Only 1 case showed periosteal reaction. Gross bony ridge was seen in 3 cases on CT scan. All the patients demonstrated isointensity or hypointensity on T1WI, and slight hyperintensity signal on T2WI. Necrosis was seen in the lesion of 10 cases. Four cases showed obvious but heterogeneous enhancement after contrast medium injection. Eight cases had soft tissue mass beyond the scope of bone destruction. Conclusions Some imaging features may suggest the diagnosis of PBMFH in long bone.

Objective To investigate the effects of moldavica total flavone on vascular endothelial growth factor (VEGF), intercellular adhesion molecule-1 (ICAM-1), nitric oxide (NO) and endothelin-1 (ET-1) in ovalbumin-induced bronchial asthmatic rats, and explore its mechanism. Methods A total of 60 SD rats was randomly divided into control group, model group, dexamethasone (1 mg/kg) group and moldavica total flavone low (90 mg/kg), medium (180 mg/kg) and high (360 mg/kg) dose group. Rats asthma model was established by ovalbumin challenge methods except the control group. After modeling, rats in control and model groups were intragastrically given distilled water, rats in medicine groups were intragastrically given moldavica total flavone and dexamethasone for 30 d. VEGF in lung tissue and ICAM-1 in bronchoalveolar lavage fluid (BALF) were detected respectively by ELISA. The content of ET-1 and NO in BALF were analyzed with radioimmunity method and nitric acid reductase method. Results The VEGF in lung tissue and ICAM-1, NO and ET-1 in BALF were decreased by moldavica total flavone at 180 and 360 mg/kg (P<0.05, P<0.01) in ovalbumin-induced bronchial asthmatic rats. Conclusion Moldavica total flavone is effective in adjusting abnormal increase of VEGF, ICAM-1, ET-1 and NO of bronchial asthma rats.
