Objective To investigate the effects of respiratory training on motor function in patients with acute stroke. Methods From 2012 to 2014, 80 patients with acute stroke were randomly assigned into treatment group and control group equally. The control group re-ceived routine rehabilitation training, while the treatment group received respiratory training in addition. All the patients were assessed with Fugl-Meyer Assessment (FMA) and modified Bathel Index (MBI) before and eight weeks after treatment. Results The scores of FMA and MBI improved more in the treatment group than in the control group (t>3.938, P<0.001) after treatment. Conclusion Respiratory training may promote the recovery of motor function in acute stroke patients.

Objective To explore the correlation between serum brain natriuretlc peptide(BNP) and cardiac function in children with pneumonia.Methods Fifty-two children with pneumonia were seleated.Among them 20 were complicated with congestive heart failure(CHF),including 9 boys and 11 girls,their ages ranging from 4 months to 4 years old;and 32 cases non-complicated with CHF,including 17 boys and 15 girls,their ages ranging from 5 months to 6 years old.Besides,there were 30 healthy children as control group,including 16 boys and 14 girls,their ages ranging from 6 months to 5 years old.For all the children,their serum BNP was measured by using ELISA met-hod,and CK-MB was measured by automatic biochemistry analyzer.In the sametime,their cardial function was measured by echocardiography.Results In the children with pneumonina complicated with CHF,the levels of serum BNP[(182.45?57.32) ng/L] and CK-MB [(48.19?16.08) IU/L] were higher than those of healthy control group[(35.12?13.84) ng/L,(11.48?4.29) IU/L Pa0.05).The levels of left ventricular ejection fraction(LVEF),left ventricle shortening fraction(FS),peak flow velocity of arteriae arota(PFVA),peak flow velocity of pulmonary artery(PFVP) in the children with pneumonia complicated with CHF were lower than those of healthy control group(Pa0.05).There was a positive correlation between the levels of serum BNP and CK-MB(r=0.28 P0.05).Conclusion The levels of serum BNP may be an important index in diagnosis of infant pneumonia complicated with CHF.

Aim To ascertain whether defibrase has the protective effect against reperfusion injury after cerebral ischemia.Methods 70 renovascular hypertensive rats(RHR) were randomly divided into defibrase group, control group and sham-operated group.Reversible middle cerebral artery occlusion(MCAO) models were produced by the modified. Longa's method,and reperfusion was begun 2 hours after occlusion.Rats in the defibrase group were given defibrase 10 U?kg-1 body weight via femonal intraveneous injection, and in the control group with the same amount of saline. The brain pieces were processed by TTC and HE staining and the infarct size,brain microvessels damage and secondary bleeding were compared between the two groups. Results The volume of infarction in the defibrase group was obviously smaller than in the control group, the damage of brain microvessels was less severe, and the bleeding lesions under optical microscope were less than in the control group. Conclusion Defibrase has protective effect against reperfusion injury post cerebral ischemia.

Objective To assess the prevalence and risk of coronary artery disease (CAD) in Chinese adults with type 2 diabetes mellitus (T2DM) using electron beam computed tomography (EBCT) and EBCT angiography (EBCTA). Methods: Ninety-four cases were enrolled in this study including diabetes (n=28), impaired glucose tolerance (IGT, n=30), coronary heart disease (CHD, n=11), and control (n=25). Cardiac EBCT plain scanning and EBCTA were performed on all of these subjects to evaluate coronary artery calcification (CAC) scores, and number of segments of stenosed coronary arteries. Both CAC and/or coronary artery stenosis were defined as patients with coronary artery lesions (CAL). Results CAC scores were not different with the control, diabetes, IGT, or CHD (P＞0.05)groups. Compared to control (0.520±1.295), more stenosed coronary arteries segments (P＜0.05) were detected in diabetes (2.964±1.915), IGT (2.200±2.024), and CHD (2.273±1.679). Number of stenosed artery segments were correlated with age (r=0.215, P=0.019),postprandial glucose (r=0.224, P=0.015), total cholesterol (r=0.323, P=0.000), and duration of diabetes (r=0.208, P=0.004). The incidences of CAL in diabetes (96.43%), IGT (93.33%), and CHD (90.91%) was substantially higher than that in normal control (56.00%, P＜0.01).The odds ratio of CAL associated with having diabetes was estimated to be 7.514 (95% CI: 1.885-63.778). Conclusions Coronary artery lesions are prevalent in Chinese adults with type 2 diabetes, implying a high CAD risk. EBCTA holds potential in depicting the details of CAL and can be used to track the progression of CAD in diabetes patients.

The result showed that TAT-haFGF(14-154) could be detected in the brain by ELISA and immunohistochemistry, the elimination of TAT-haFGF(14-154) in rat was swift, and TAT-haFGF(14-154) could penetrate across the blood-brain barrier, distribute in pallium and hippocampus and locate in the nucleus.

Objective To explore the effect of the gene silencing of phosphatidic acid-preferring phospholipase A1 (PA-PLA1) on insulin secretion in mouse insulin-secreting cell line MIN6. Methods The siRNA expression vector of mouse PA-PLA1 gene targeting was constructed using mouse PA-PLA1 mRNA sequence available in GenBank, and MIN6 cells were transfected with the vector. Fluorescence quantitative PCR and Western-blotwere applied to screen efficient RNAi-vector. After transfection with obtained efficient RNAi-vectors for 48 hours, glucose-stimulated insulin secretion experiments were conducted, and the changes of insulin secretion were examined. Results Four siRNA expression vectors of mouse PA-PLA1 gene targeting were confirmed to be successfully constructed by the analyses of enzyme cleavage and sequencing. The results of fluorescence quantitative PCR and Western blot analyses indicated that the siRNA expression vectorpGPU6-PA-PLA1-1885was the most effective RNAi-vector in the four vectors. The expression levels of the PA-PLA1 mRNA and protein of the MIN6 cells transfectedwith pGPU6-PA-PLA1-1885 decreased to 46.3% and 33.9% of that of the control, respectively, and meanwhile the insulin secretion levels of the cells decreased to 65.0% of that of the control (P < 0.05). Conclusion The gene silencing of phosphatidic acid-preferring phospholipase A1 might decrease insulin secretion in MIN6 cells.
