Objective To explore whether dexmedetomidine(Dex)could mitigate acute lung in-jury induced by hind limb ischemia reperfusion(I/R).Methods One hundred and twenty SD rat weigh-ting 250-300 g were allocated to receive hind limb I/R,I/R plus Dex (25 μg/kg Dex was intraperitoneal in-jection 30 min before ischemia)and norm control group,and each group was further divided into five sub-groups:before operation and 4 h ischemia followed by 0,1,3 and 6 h reperfusion.After euthanization,lung W/D weight ratio,PaO2 ,SOD,MDA and TNF-α were determined.Results Compared with group C, hind limb I/R injury significantly increased serum TNF-α concentration and W/D ratio,with significantly decreasing PaO2 level at any time of reperfusion in the group I/R,the concentration of MDA increased and the SOD activity decresed at 1,3,6 h of reperfusion.Conversely,W/D ratio as well as the concentration of TNF-αin the serum of the I/R plus group Dex were significantly lower than those of the I/R at 6 h of reperfusion,PaO2 level increased respectively;the concentration of MDA decresed at 1,3,6 h of reperfusion and the SOD activity increased at 3,6 h of reperfusion in I/R plus group Dex.Conclusion Dex mitigates a-cute lung injury induced by unilateral hind limb I/R in rats.The mechanisms may involve attenuating oxida-tive stress and inhibiting inflammatory response.

Objective To observe the effectiveness of Chinese herbal medicine plus movement therapy in treating upper limb spasticity in hemiplegic patients. Methods Sixty-six patients were divided randomly into two groups. Thirty-five patients in the therapy group were treated with Chinese herbal medicine and movement therapy, and 31 patients in the control group were treated with movement therapy alone. The modified Ashworth scale and sur- face electromyography were applied to evaluate spasticity. Results The total effectiveness rates were 94.3% in the therapy group and 64.5% in the control group. After treatment, the average integrated electromyogram (IEMG) val- ue in the therapy group was lower than that in the control group. The difference in IEMG values before and after treat- ment in the therapy group was significantly larger than in the control group. Conclusion Chinese herbal medicine plus movement therapy is more effective than movement therapy alone in relieving spasticity.

Budd-Chiari syndrome (BCS) is a rare disease. Because of lack of clear characteristic symptoms in the early stage, many patients are misdiagnosed or never diagnosed. Early diagnosis and prompt treatment play a key role in improving survival rates and quality of life for BCS patients. With the progress in imaging techniques, the radiological examination is playing more and more important role in the diagnosis and assessment of BCS. Ultrasound, computed tomography, magnetic resonance imaging and digital subtraction angiography are all helpful in evaluating the obstruction of hepatic vein and inferior vena cava. Thus, these imaging tests should be used rationally according to their features. On the other hand, the interventional therapy is the preferred method for the treatment of BCS. This paper intends to get a deeper understanding of BCS for clinicians, which is essential for patients to be diagnosed in time.

Objective To investigate the influencing factors of hemorrhagic transformation in non-thrombolysis patients after acute cerebral infarction. Methods According to Chengdu Stroke Registry Project,2598 consecutive patients with acute cerebral infarction admitted to the Department of Neurology,West China Hospital within 1 week of attack from January 2010 to December 2013 were enrolled prospectively. The patients were divided into a hemorrhagic transformation group and a non-hemorrhagic transformation group according to whether they had hemorrhagic transformation or not. As for patients with hemorrhagic transformation,they were divided into a symptomatic hemorrhagic transformation (SHT)group and an asymptomatic hemorrhagic transformation (ASHT)group according to whether they had aggravation of symptom and sign. The baseline data of all patients were collected and compared between the groups. The P<0. 1 variables of the univariate analysis result were enrolled in multivariate logistic regression analysis in order to identify the independent influencing factor of hemorrhagic transformation. Results In 2598 patients,249 (9. 6%)had hemorrhagic transformation,28 of them (1. 1%)were SHT and 221 (8. 5%)were ASHT. There were significant differences in male,hypertension,dyslipidemia,atrial fibrillation,drinking and smoking ratio,blood glucose,cholesterol,low density lipoprotein cholesterol, National Institutes of Health Stroke Scale (NHISS)scores,and the trial of Org 1072 in acute stroke treatment (TOAST)classification between the HT group and the non-HT group (all P<0. 05). There were no significant difference in the related influencing factors between the SHT group and the ASHT group (all P>0. 05). The results of multivariate logistic regression analysis showed that dyslipidemia (OR,0. 588, 95%CI 0. 374-0. 924,P=0. 021)was negatively correlated with hemorrhagic transformation. Atrial fibrillation (OR,3. 188,95%CI 2. 159-4. 707,P<0. 001),blood glucose (OR,1. 081,95%CI 1. 044-1. 119,P<0.001),and NHISS score (OR,1. 305,95%CI 1. 170-1. 455,P<0. 001)were positively correlated with hemorrhagic transformation. In TOAST classification,relative to the large atherosclerotic stroke,the small artery occlusive cerebral infarction was negatively correlated with hemorrhagic transformation (OR,0. 315, 95%CI 0. 167-0. 596,P<0. 001). After removing the influencing factor of atrial fibrillation,compared with the large artery atherosclerotic stroke,cardioembolism stroke was positively correlated with hemorrhagic transformation (OR,2. 823,95%CI 1. 946-4. 095,P<0. 001). Conclusion Dyslipidemia,atrial fibrillation,blood glucose,NHISS score and TOAST classification were independently associated with hemorrhagic transformation in non-thrombolysis patients after acute cerebral infarction.
