RESUMEN
I-scan technology is the newly developed image enhanced endoscopy technology from PENTAX,Japan,which can visualize the capillary and the gap of glandular duct of gastrointestinal mucosa.i-scan images are as bright as conventional white-light images.Therefore,i-scan is able to observe much larger areas in a distant view compared with NBI.It has a broad application prospects.However,due to the lack of a unified diagnostic standard,the application of i-scan technology needs further study.This review summarizes the applications of high-resolution electron-staining endoscopy in the diagnosis of gastrointestinal diseases.
RESUMEN
ObjectiveTo observe the clinical effect of warm needling based on conventional rehabilitation in treating cerebral palsy.MethodSixty patients with cerebral palsy were randomized into an observation group and a control group, 30 in each group. The control group was intervened by physiotherapy (PT), occupational therapy (OT), speech therapy (ST), conductive education (CE), etc.; the observation group was by mild moxibustion at Baihui (GV20), Zusanli (ST36), and Guanyuan (CV4) in addition tothe above rehabilitation therapies.ResultThe rehabilitation result in the observation group was superior to that inthe control group (P<0.05).ConclusionMild moxibustion can significantly enhance the rehabilitation result in patients with cerebral palsy.
RESUMEN
Objective To evaluate the value of i-Scan in the diagnosis of Barrett′s esophagus.Methods 52 patients diagnosed with Barrett′s esophagus by gastroscopies and pathological examinations were observed under the ordinary edoscopy and i-Scan respectively.Besides,the Barrett's esophageal mucosa were classified by Endo with i-scan mode, the target lesions was taken to be biopsied and pathologically examined.Results ( 1 ) In the 52 patients,mucosal lesions were found in 46 cases (88.5%) under i-Scan and 35 cases (67.3%) under ordinary edoscopy respectively,mucosal lesion detection rate in i-Scan was significantly higher than normal white mode( P<0.01).In the 33 patients which found mucosal lesions in the two modes,the definition of lesion margins,morphology of lesion cryptaeand mucosa capillaries revealed by i-Scan were superior to that by white lighted endoscopy ( P<0.05);(2) Under i-scan mode,the detection of specific intestinal metaplasia ( SIM) of typeⅣ,type V in sensitivi-ty,accuracy,specificity were respectively 90.0%,93.5%,94.4%.Conclusion i-Scan is very easy to operate and has a clear lesion of Barrett′s esophagus,which helps to target the lesion at pathological biopsy.
