Objective To observe the early rehabilitation effect of mild hypothermia on patients with herpes simplex viral encephalitis (HSE). Methods A total of 58 patients with HSE were randomized into two groups, a mild hypothermia therapy group (30 cases) and a normothermia control group (28 cases). Their rectal temperatures were controlled to (34±1)℃ and (37.0±0.5)℃ respectively. Serum levels of neuron specific enolase (NSE) were determined through radio-immunoassay (RIA). Soluble intercellular adhesion molecule-1 (sICAM-1) was measured with ELISA before and 1, 3, 5, and 7 d after treatment. The outcome was evaluated using the Glasgow Outcome Scale (GOS) 30 days after treatment. Results Compared with the normothermia control group, the mild hypothermia group's serum levels of NSE and sICAM-1 decreased quickly and significantly during the early stage of treatment and remained better 30 d later. Conclusion Mild hypothermia therapy can dramatically reduce inflamma-tion and facilitate the rehabilitation of damaged neurons, provide protective effects and improve the outcome for pa-tients with SHE.

OBJECTIVE:To provide reference for better improving the risk perception of Omeprazole sodium for injection in nurses in a third-grade class-A hospital,strengthening risk management of ward drugs and ensuring safety of patients. METHODS:Nurses in the clinical departments in a third-grade class-A hospital where usage frequency of Omeprazole sodium for injection was relatively more were adopted as study subjects and a self-designed questionnaire was used to investigate on related knowledge on medication risk in nurses in emergency department,gastroenterology department,ICU and CCU in 2012 and 2014. RESULTS:51 and 81 questionnaires were distributed in 2012 and 2014,and 51 and 81 were effectively received with effective recovery of 100%and 100%,respectively. In both surveys,100% surveyed nurses could correctly choose one solvent at least,1.96% and 3.70%nurses could correctly choose 2 solvents;correct answering rates of intravenous administration time were 94.12% and 96.30%,re-spectively;correct answering rates of stable duration after preparation were both lower than 9%;correct answering rates of adverse reaction of this drug were 3.92% and 1.23%,respectively;correct answering rates of interaction of this drug were 1.96% and 6.17%,respectively;correct answering rates of stable formulation of this drug were 17.65%and 22.22%,respectively;the propor-tion of nurses observing ADRs were 25.49% and 13.58%,respectively;the proportion of nurses finding inappropriate compatibility were 15.69% and 22.22%,respectively,Ornidazole and sodium chloride injection was the most used incompatible drug;45% or more nurses hoping to strengthen the continuing education of nursing personnel. CONCLUSIONS:Nurses in this third-grade class-A hospital lack certain knowledge on the medication risk of Omeprazole sodium for injection,the drug risk management is not sufficient,and awareness prevention of drug risk is relative weak. It is suggested that the hospital should strengthen drug risk management system,nurses should strengthen the learning about drug risk and play the role of clinical pharmacists in the drug risk management to reduce the related drug risk and incidence of adverse reactions.

Objective To determine the relationship between cigarette smoking and the incidence of systemic lupus erythematosus.Methods Database including Cochrane Library,Pubmed,OVID and Elsevier were electronically searched to collect case-control and cohort studies on the relationship between cigarette smoking and incidence of systemic lupus erythematosus.The literatures were screened and the data were extracted independently according to the inclusion and exclusion criteria.The quantitative analysis were performed by using Stata 12.0 software.Results The pooled OR values (95％ confidence interval)of current smoking and ever smoking were 1.82 (95％CI 1.42～2.34) and 1.22 (95％CI 0.96～1.56) respectively.Conclusions Our Meta-analysis revealed a moderate but statistically significant association between current smoking and development of systemic lupus erythematosus.However,it is still not confirmed whether the past smoking is one of the risk factors of systemic lupus erythematosus.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Objective To investigate appropriate diagnosis and treatment of solitary fibrous tumor of the pleura (SFTP).Methods Clinical and pathological data of ten patients treated in our hospital from 2002 to 2007 were reviewed. Results Our series consisted of three men and seven women. In two patients correct diagnosis was made before operation through ultrasonography-gnided core needle biopsy. All the patients were treated surgically including three resected by video-assisted thoracic surgery (VATS). Histopathologically, five tumors were malignant and the other five were benign. Immunohistochemical staining showed malignant SFTP (3/5) were less frequently positive for CD34 than benign group (5/5). Nestin was only detected in malignancies (2/5), which were negative for CD34. Except for one, all patients were followed-up for 6 to 35 months (mean 17.3 months). One patient experienced a recurrence and one died of brain metastasis. Conclusion Ultrasonography-guided core needle biopsy combined with immunohistochemical analysis is a safe and rapid method to provide a confirmatory diagnosis before surgery. For smaller, pedunculated tumors, VATS may be a bettor approach. Besides, we speculated CD34-negative and nestin-posifive might be a malignant marker for SFTP.
