Objective To explore risk factors of neurosurgical patients in bed with deep vein thrombosis (DVT) and to compare the Autar Scale with the Caprini Scale for predicting DVT formation. Methods Retrospective analysis of DVT risk factors was conducted on sixty-eight cases neurosurgical patients in bed of three hospitals. In addition, used two kinds of risk assessment scales to assess patient′s level of DVT risk. Results Coma (OR=9.410,95%CI=1.689-52.423), paralysis (OR=4.950,95%CI=1.432-17.105) , infection (OR=2.927,95%CI=1.162-7.373), lower limb central venous catheterization (OR=6.072,95%CI=2.187-16.858) may be risk factors for DVT in neurosurgical patients in bed. The two risk assessment tools were used within 24 hours after admission (χ2=34.861) and within 24 hours after surgery (χ2=52.869) to predict differences in neurosurgical patients with thrombosis risk level, with statistical significance (P < 0.01). Conclusions Nurses should identify risk factors of DVT every day and take preventive measures early to reduce the risks. The Caprini Scale is better than the Autar Scale for predicting DVT formation.

Objective To investigate the effect of Artesunate (Art) on experimental immune myositis (EIM) animal model. Methods Guinea pigs were immunized with rabbit muscle homogenate in Freund′s adjuvant, and a generalized myositis fundamentally similar to human polymyositis was established. These animals were divided into two groups: the control group (injected intraperitoneally with normal saline everyday) and the treatment group (injected intraperitoneally with Art everyday). Results The serum levels of CPK, AST and LDH were significantly lower in the treatment group than those in the control group. EMG demonstrated that the treatment group kept improving along with the elapse of time. Histological findings revealed that the damage of muscle in the treatment group was less severe than that of the control group. Conclusion Art is effective in therapy of EIM guinea pigs. The result of this study provides a reliable evidence that Art might be used for the treatment of PM/DM and other immune diseases.

Objective To explore the risk factors of lower extremity deep venous thrombosis (LEDVT) of neurosurgical patients, and to provide references for identifying the most susceptible population and taking preventive measures. Methods A total of 68 cases of neurosurgical patients with LEDVT in three general hospitals from August 2010 to August 2013 were collected. The design method of one to one matching case-control study was used controlling age, sex and neurosurgical disease. Univariate and multivariate analyses were performed to determine the probable risk factors among two groups. Results The univariate analysis showed that coma, paralysis and limb immobilization, infection, trauma and fracture, lower limbs central venous catheterization, trachea cannula or tracheotomy, mechanical ventilation, surgical operation, dehydration and blood transfusion were significantly related to the incidence of LEDVT ( Χ2=4.50-33.23, P<0.05 or 0.01). The Logistic multivariate regression analysis showed that coma (OR=9.410, 95%CI 1.689-52.423), paralysis and limb immobilization (OR=4.950, 95%CI 1.432-17.105), infection (OR=2.927, 95%CI 1.162-7.373) and lower limbs central venous catheterization (OR=6.072, 95%CI 2.187-16.858) were independent risk factors for the development of LEDVT. Conclusions We should pay attention to patients with high risk factors of LEDVT and take preventive measures early to avert the formation of LEDVT.
