ObjectiveTo observe the effect of transcutaneous electric nerve stimulation(TENS)on function recovery in patients with stroke. Methods60 patients who suffered from stroke within 14 days were divided into treatment group (30 cases) and control group (30 cases). All the patients accepted Motor Relearning Programme (MRP),otherwise patients in treatment group were treated with TENS.Before and after treatment, two groups were assessed with Fugl-Meyer Assessment (FMA) and Barthel Index. ResultsThere was significant difference in FMA and Barthel Index after treatment between two groups (P<0.05,P<0.01).Conclusions Early using TENS can improve function of motion and ADL in patients with stroke.

Objective To assess the diagnostic value of confoeal laser endomicroscopy(CLE) in histological gastritis.Methods A total of 149 patients underwent CLE.Standard locations and focal lesions were examined by confocal imaging, and specimens were taken by targeted biopsy.The relationship between confocal images and histological findings were studied systemically.Results The sensitivity,specificity and accuracy of CLE in diagnosis of atrophy were 83.6%,99.6%and 97.5%,respectively;and those in moderate to severe neutrophil infiltration were 81.9%,99.3%,and 95.8%,respectively.The mean kappa values for inter-and intra-observer agreement on the classification of confocal images in groups were 0.749 and 0.811 respectively.Conclusion The validity and reproducibility of CLE in diagnosis of histologic gastritis are promising,which might warrant its further application in clinical practice.

Objective To evaluate the efficacy of confocal laser endomicroscopy(CLE)for the assessment of the grading of gastric intestinal metaplasia(GIM)in vivo.Methods Patients with known GIM underwent CLE(Pentax EC-3870K).The presence of GIM was indentified immediately by the endoscopist during the procedure.The updated Sydney Classifycation System as reference,GIM was subdivided as mild,moderate and severe according to the area of intestinal metaplasia glands and the number of goblet cells.The histological evaluation remained the gold standard for the final diagnosis of GIM.The presence of the dysplasia and the expression of the Ki67 were examined.Results A total of 151 GIM positive areas were found in 58 patients with mild in 92,moderate in 34.and severe in 25 by CLE. One hundred and forty-six GIM areas were examined histopathologically with positive rate of 96.7%(mild in 82,moderate in 36 and severe in 28).The sensitivity and specificity of CLE were 90.2%and 73.9%in diagnosis of mild GIM,69.4 oA and 92.2%in moderate GIM,71.4% and 95.9%in severe GIM.The kappa coefficient of CLE criteria and the histopathological grading for mild,moderate and severe GIM were 0.65,0.63 and 0.70,respectively.The more severe the GIM,the higher the ratio of incomplete GIM,the ratio of dysplasia and the stronger expression of Ki67.Conclusions CLE may offer an instant and reliable diagnosis for GIM with high accuracy.It is helpful in grading of GIM.
