Objective To observe the effect of electromyographic biofeedback combined with swallowing training on dysphagia after stroke.Methods Ninety-five patients with difficulty in swallowing after stroke were randomly divided into a treatment group (48 eases) and a control group (47 cases).The patients in the treatment group were provided electromyographic biofeedback and swallowing training; the patients in the control group received swallowing training only.The therapeutic effect was assessed with Kubota's drinking water test before treatment and 30d after treatment.Results Swallowing in both groups improved after treatment.The total recovery rate in the treatment group was 87.5％,and in the control group it was 68.0％,a significant difference.Conclusion Electromyographic biofeedback can improve the effectiveness of swallowing training after stroke.

AIM: To evaluate the effect of carbon monoxide(CO) on the permeability of brain blood barrier(BBB) in cerebral ischemic rats. METHODS: SD rats were divided into three groups. Saline, hemin or ZnPP were injected intraperitoneally 12 h before middle cerebral artery occlusion (MCAO), respectively. The concentration of blood CO and the permeability of BBB at 24 h after MCAO were measured. RESULTS: The CO concentration in blood in hemin group was higher than that in saline group( P 0.05). CONCLUSION: CO reduced the permeability of BBB as a messenger gas molecular when its intrinsic concentration was elevated.

ObjectiveTo observe the effect of transcutaneous electric nerve stimulation (TENS) and physical therapy on shoulder pain after stroke. Methods60 patients of shoulder pain after stroke were randomly divided into treatment group (30 cases) and control group(30 cases). The patients in the treatment group were treated with TENS and physical therapy. The cases in the control group were treated with TENS only. All patients were evaluated with visual analogous score of pain (VAS) and Fugl-Meyer measure (FM) before and after treatment. ResultsThe scores of VAS and FM improved more significantly in treatment group than in control group(P<0.01).ConclusionTranscutaneous electric nerve stimulation combined with physical therapy showed more effective on shoulder pain after stroke.

Objective To determine the effectiveness and medical cost-effectiveness of clinical rehabilitation for promoting the functional recovery of sub-acute cerebral infarction patients.Methods Totally 247 sub-acute patients with cerebral infarction were randomly divided into a clinical rehabilitation group of 129 and a routine rehabilitation group of 118.The clinical group received a standardized rehabilitation intervention and drug treatment,while the routine rehabilitation group received routine rehabilitation therapy and drug treatment.The Fugl-Meyer assessment (FMA) and the modified Barthel index (MBI) were used to compare the two groups after the treatment and 3 and 6 weeks later.The hospital cost for six weeks was also compared between the 2 groups.Results At 3 and 6 weeks,improvement in the average FMA and MBI scores was observed in both groups but the inter-group differences were not significant.The total hospital cost of the clinical group was,however,significantly less than that of the others.Conclusion Clinical rehabilitation can improve the motor function and ability in the activities of daily living of stroke patients.It also has economic benefits.

Objective To observe effect of scalp acupuncture combined with cognitive rehabilitation training in ameliorating cognitive dysfunction in stroke patients. Methods Eighty-four stroke patients with cognitive dysfunction were randomly divided into a treatment group ( n = 42) and a control group (n = 42 ) . All of the patients in both groups received routine therapy including cognitive rehabilitation training by professional therapists aimed at improving their orientation, perception, attention and thinking. The patients in the treatment group also received prolonged scalp acupuncture, in which the acupuncture needle remained in the scalp for 6 hours. All cases were evaluated using Loewenstein's occupational therapy cognition assessment (LOTCA) before and 10 weeks after treatment. Results The LOTCA scores were significantly different before and after treatment in both groups. The effect in the treatment group was significantly better than in the control group. Conclusions Prolonged scalp acupuncture combined with cognitive rehabilitation training can significantly improve the cognitive ability of stroke patients.

Objectives To investigate the ability of T1 mapping and intravoxel incoherent motion imaging (IVIM) parameters for evaluating renal allografts at the early stage after renal transplantation. Methods This prospective study protocol was approved by the local ethics committee, and written informed consent was obtained from all subjects. Sixty two recipients 2 to 4 weeks after kidney transplantation and 20 healthy volunteers (control group) underwent routine MRI, T1 mapping, and IVIM imaging (11 b values, 0 to 700 s/mm2). Recipients were divided into two groups base on their estimated glomerular filtration rate (eGFR):37 recipients with good allograft function (eGFR≥60 ml·min-1·1.73 m-2) and 25 recipients with impaired allograft function (eGFR<60 ml·min-1·1.73 m-2). The ADC, true diffusion coefficient (ADCslow), pseudo-diffusion coefficient (ADCfast), perfusion fraction (f) and T1 values were measured on both cortex and medulla. Differences among groups were compared using the one-way analysis of variance. Correlations between eGFR and the parameters in renal allografts were assessed by using Pearson correlation analysis. ROC was performed to assess the diagnostic utilities of using these parameters to discriminate allografts with impaired function from good function. Results Excepting for cortical T1, ADCfast and medullary T1, f values, allografts with good function showed no differences in other parameters compared with healthy control. Excepting for medullary T1 and ADCfast,the other values showed significantly differences in allografts with impaired function compared to allografts with good function (all P<0.05). Excepting for medullary f and ADCfast values, allografts with impaired function showed significantly differences in the parameters compared with good function group(all P<0.05). In renal allografts, excepting for medullary T1, ADCfast, and f values, cortical T1 exhibited a negative correlation with renal function, and there was a significant positive correlation between eGFR and other parameters. Cortical T1 value showed high sensitivity(91.9%) to discriminate renal allografts with different function, with the threshold of 17.36 × 102 ms, and ADC value showed high specificity(96.0%)with the threshold of 1.98 × 10-3 mm2/s. Conclusion T1 mapping and IVIM technique may be useful for detecting renal allograft dysfunction, and be a reliable imaging for evaluating and monitoring allograft function.

AIM To speculate the hypoglycemic mechanism for rats with type 2 diabetes by exploring the therapeutic effects of leaf aqueous extract from Cyclocarya paliurus on liver insulin receptor (InsR) and insulin receptor substrate 2 (IRS-2).METHODS The diabetic rat model was established through intraperitoneal injection of streptozotocin and fed with high-fat diet.The moleled rats were equally assigned into the control group and leaf aqueous extract from Cyclocarya paliurus group (extract group).After the test extract was orally administrated for four weeks,body weight,urine output,food intake,water intake and fasting blood-glucose (FBG) were measured,and the levels of serum insulin,InsR and IRS-2 mRNA in liver tissue were investigated in rats.RESULTS Compared with the control group,the extract group showed a reduction in urine output,food intake,water intake,FBG and insulin levels.Meanwhile,the rats' body weights in extract group were presented a trend to increase.The gene expressions of InsR and IRS-2 in liver tissue were up-regulated.Moreover,the insulin sensitivity was improved.CONCLUSION The leaf aqueous extract from Cyclocarya paliurus can reduce FBS,improve insulin sensitivity,which may be associated with the increase of InsR and IRS-2 gene expression in liver tissue.

Objective:To characterize the clinical and epidemiological changes, treatments, and prognoses of primary esophageal small cell carcinoma (PESC). Methods:A retrospective analysis was conducted using the clinical epidemiology data of 529 PESC patients se-lected from the clinical databases of 500,000 esophageal and gastric cardiac carcinomas of the Henan Key Laboratory for Esophageal Cancer Research (1992-2015). Among these patients, 241 cases were included in the survival analysis. The five-year survival rate was calculated using Kaplan-Meier analysis, and the differences in survival rates were compared using the Log-rank analysis model. Re-sults:All 529 PESC cases were analyzed, which accounted for 0.2%of esophageal cancers diagnosed in the same period. The incidence of PESC increased annually (R2=0.574). The survival rates for 1-, 2-, 3-, and 5-year of 241 PESC patients were 55%, 40%, 29%, and 9%, respectively, and the median survival time was 21.9 months. On the basis of the VALSG criteria of lung small cell carcinoma, a statisti-cal difference was observed in the overall survival rates for limited and extensive diseases (P=0.003), with the median survival time of 24.3 and 17.5 months, respectively. Furthermore, significant differences were observed on survival with various treatment modalities (P=0.004). The median survival time of PESC patients treated with combined surgery and radiochemotherapies (28.8 months) was lon-ger than those with either chemotherapy (17.8 months, P=0.015) or chemoradiotherapy (14.5 months, P=0.004). In limited disease pa-tients, the median survival time was longer in patients treated with surgery (27.7 months) than in those without surgery (16.2 months, P=0.007). Notably, the biopsy diagnosis before surgery for PESC was only 40.8%. Conclusion:PESC is a rare malignant carcinoma with increasing incidence. PESC presents poor prognosis, and the survival rate can be improved through combined therapies based on sur-gery. A high misdiagnosis rate for PESC is observed before surgery with biopsy.

Objective：To investigate the mechanism of increased glucose uptake, the expression of myoc ardial glucose transporter1 (GLUT1) was determined after low-flow myocardial is chemia. Methods： An in vivo open-chest canine model of low -flow myocardial ischemia was used to correlate myocardial glucose uptake with the number of GLUT1. The expression of myocardial GLUT1 glucose transporter was determined by semiquantitative Northern blotting and immunoblotting. Res ults： GLUT1 mRNA and GLUT1 polypeptide expression was substantially inc reased in ischemic region from the experimental hearts when compared to normal h earts. There was no significant regional difference in GLUT1 expression in eith er normal or ischemic hearts.Conclusion：Myocardial ischemia ind uces a factor or factors which stimulate GLUT1 expression in ischemic myocardial regions. Enhanced GLUT1 expression may be an important protective mechanism by which myocardial cells enhance glucose uptake and metabolism during low-flow my ocardial ischemia.
