Objective To investigate the causes of the complications occurred after repeated embolization therapy for huge cerebral arteriovenous malformations and to discuss their nursing interventions. Methods A total of 54 embolization procedures were performed in 17 patients with huge cerebral arteriovenous malformations. The clinical data were retrospectively analyzed. The causes of complications were carefully examined and the preventive measures were discussed. The prompt and necessary nursing interventions were formulated in order to prevent the complications or serious consequences. Results Among the total 17 patients, one patient gave up the treatment because of the cerebral hemorrhage which occurred two months after receiving 3 times of embolization therapy. One patient experienced cerebral vascular spasm during the procedure, which was relieved after antispasmodic medication and no neurological deficit was left behind. Two patients developed transient dizziness and headache, which were alleviated spontaneously. One patient presented with nervousness, fear and irritability, which made him hard to cooperate with the operation and the basis intravenous anesthesia was employed. No complications occurred in the remaining cases. Conclusion The predictive nursing interventions for the prevention of complications are very important for obtaining a successful repeated embolization therapy for huge cerebral arteriovenous malformations, which will ensure that the patients can get the best treatment and the complications can be avoided.

Objective To stndy the clinical efficacy of bicyclol treatment for chronic hepatitis B.Methods 70 cases of chronic hepatitis B patients were randomly divided into 2 groups;35 cases in test group,with bicyclol 75mg daily,and 35 cases control group,in with SNMC 150mg daily patients in the 2 groups got continuous medication for 12 weeks.levels of serum aminotransferase changes before and after treatment were observed.Results Serum aminotransferase decreased more significantly in test group(P

AIM: Agricultural and industrial wastes, such as deteriorated corns and oil foots, were used as slow-release materials to prepare biodegradable puffed fertilizers, with urea was encapsulated in fertilizer particles with three-dimensional (3D) skeleton construction.METHODS: Slow-release materials formed 3D skeleton construction through modified treatments, swelling, comminution,extrusion and pelleting. Also 3D skeleton construction and its scales were modified by alternating technical conditions,species and ratio of materials in order to realize the controlled-release of fertilizers.RESULTS: Puffed slow-release fertilizers were prepared. And 3D skeleton construction formed as a compact protective layer on surface of fertilizer particles, whose coating fraction of urea was larger than 85%, the number of pin hole (larger than 20 nm) was lower than 20%, and thickness of membrane was larger than 30 nm. The protective layers of samples in soil were biodegraded and pulled out by microbes. Therefore fertilizer particles emerged gradually and dissolved into soil. Slow release of puffed fertilizers was a continuous process containing degradation, abscission and dissolution. And the whole procedure did not yield any polluting residuals. Release experiments in water showed that pure urea (100%) dissolved absolutely in 10 minutes, whereas only 8.2% urea was released from samples with urea content 85.50% after 120 minutes.And similar experiments in soil illuminated that 85% urea was dissolved from pure urea (100%) in 20 hours, whereas 1.3% and 0.8% urea was released from puffed slow-release fertilizers with urea content 81.5% and 40.9% respectively. Therefore,the release rate of slow-release puffed fertilizers was only 1/65.38 and 1/106.25 to that of pure urea.CONCLUSION: Compared with pure urea, the release rates of puffed slow-release fertilizers in both water and soil are apparently low. Furthermore, puffed slow-release fertilizers have good biodegradability (＞95%), which can improve the construction of soil and increase the content of organic fertilizers.

Objective To evaluate the efficacy of deanxit in treatment of post-stroke depression (PSD).Methods60 patients with PSD were randomly divided into treatment group ( plus with deanxit) and control group (plus with estazolam necessarily). At the baseline and at 2 weeks,4 weeks, 8 weeks after the treatment, the efficacy was assessed with HAMD, SSS, and ADL rating scale respectively. Results After 2,4,8 weeks treatment, HAMD and SSS scores of the treatment group significantly decreased compared with the control group ( all P ＜ 0. 01 ), and ADL scores of the treatment group increased significantly compared with the control group ( P ＜ 0. 01 ). Conclusion Deanxit could effectively relieve depressing symptoms and neurological impairment of PSD, and clinical side effects of deanxit were less. Deanxit was suitable for acute phase and long-term maintenance therapy in PSD.

Objective To observe the value of detection of pulmonary arterial hypertension(PAH) with curvature ratio measured at cardiac MR.Methods We performed a retrospective study of 48 patients with cardiac MR,systemic systolic blood pressure and right heart catheterization(RHC) data.The parameter curvature ratio (Rc) was measured at cardiac MR and transseptal/transmural pressure ratio (RP) was calculated.By using the regression analysis between Rc and RP,the SPAP was calculated.Bland-Altman analysis was used to compare the SPAP calculated with SPAP obtained by RHC.The accuracy of the SPAP calculated in detecting PAH was analyzed by using receiver operating characteristic (ROC) curves (SPAP higher than 40 mmHg as cutoff).The normality of parameter is tested by K-S test.Bivariate correlation Pearson test was used to test the consistency of parameters obtained by different measurers.Linear regression analysis was performed to find the relationship between Rc and RP.Results Parameter RP =0.28 ± 0.37 (-0.50-0.83) and RC =0.31 ± 0.57 (-0.78-0.97).Linear relationship was found between Rc and RP (r =0.94,P ＜ 0.01) and regression equation:Rc =1.44 × RP-0.09.Bland-Altman analysis showed satisfactory limits of agreement with the SPAP calculated and obtained by RHC.ROC analysis of the diagnostic value in PAH revealed 94.4％ (34/36) of sensitivity and 100.0％ of specificity (12/12,area under ROC curve =0.942,P ＜ 0.01).Conclusions Our study suggests that with curvature ratio measured at cardiac MR,the SPAP estimated have considerable sensitivity and specificity for detecting PAH.It may be a useful non-invasive assessment in patients that suspected of PAH.

The silver doped poly ( L-lysine ) modified glassy carbon electrode was fabricated by cyclic voltammetry, the surface of the electrode was characterized by scanning electron microscopy and electrochemical impedance spectroscopy. The electrochemical behaviors and the simultaneous detection of xanthine and uric acid were studied by cyclic voltammetry and differential pulse voltammetry. The results indicated that this modified electrode exhibited excellent electrocatalytic activity towards the oxidation of xanthine and uric acid. The stable oxidation peaks of xanthine and uric acid appeared with the peak potential of 0. 980V and 0. 600V respectively at the modified electrode in pH 3. 0 phosphate buffer solution. The oxidation peaks of xanthine and uric acid were separated at 380 mV. Under the optimum conditions, the linear ranges for the determination of xanthine and uric acid were 1 . 00 × 10-6-2 . 50 × 10-4 mol/L respectively by differential pulse voltammetry. The detection limits were 5. 0×10-7mol/L. The method has been applied to the simultaneous detection of xanthine and uric acid in healthy human urine with satisfactory results.
