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.

Chemotherapy induced thrombocytopenia( CIT) is a major dose-limiting hematologic toxicity with cancer patients.Aside from bleeding risk, thrombocytopenia limits chemotherapy doses and frequencies. While platelet transfusion is remain the elementary method for CIT,administration of platelet growth factors,such as recombinant human interleukin-11(rhIL-11),recombinant human thrombopoietin(rhTPO)and thrombopoie-tin receptor agonist(TPO-RA),are convenient and effective platelet-support strategies for patients receiving myelosuppressive chemotherapy.In addition,other cytokines and proximal splenic artery embolization( PSAE) are expected to be new clinical therapies.In this review,we summarize the existing data and approaches in the treat-ment progress of CIT.

Objective:To examine the expression of integrin ?V?3 in periodontium during experimental tooth movement, and then to propose the possible role of ?V?3 in bone remodeling during tooth movement. Methods:Thirty-five rabbits were divided into 7 groups (5 rabbits per group):untreated(control), 1,3, 5, 7, 14 and 21 d groups. A elastic coil spring was ligated between the incisors and the first molar and exert a force of approximately 0.78 N to pull the first molar mesially. The animals were sacrificed at each time intervals(1,3,5,7,14 and 21 d) respectively and specimens were made to observe the expression of integrin ?V?3 in periodontium through in situ hybridization. Results:Different extent expression of integrin ?V?3 were seen in osteoclasts, osteoblast precursors, osteoblasts,odontoclasts and odontoblast except bone cells. Conclusions: Integrin ?V?3 may play an important role in bone modeling, cementum resorption and its reparation during experimental tooth movement.

Arsenic exposure can cause health problems to our body but arsenic can also be used to treat some diseases through induction of cell apoptosis.These effects are due to arsenic toxicity,but the mechanism is still unclear.Recent studies have showed that cell apoptosis induced by endoplasmic reticulum stress is associated with the mechanism.Therefore,in this paper,the role of endoplasmic reticulum stress in arsenic toxicity has been reviewed and some problems in current studies are pointed out,so as to provide clues and basis for further scientific research.

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.
