Results The curative effect was 94.3% in the treatment group while 76.8% in the control one (P < 0.05), which had statistical meaning. Conclusion Interventional therapy by CT localization combined TCM on prolapse of lumbar intervertebral disc had better effect and shorter treatment course.

Objective To observe the effects of peritoneal ventilation with pure oxygen in the rabbits with hypoxaemia and hypercapnia induced by mechanical controlled hypoventilation.Methods Sixteen rabbits were invasive|y ventilated after trachea incision.Hypoxaemia and hypercapnia were induced by hypoventilation which was implemented both by degrading ventilation parameters and respiratory depression induced by intravenous infusion of muscle relaxant.Then pure oxygen was insufflated into the peritoneal cavity and arterial blood gases were measured every 30 minutes for two hours.Results The PaO2 was (52.50±3.46)mm Hg at baseline and increased to (76.46±7.79) mm Hg, (79.62±9.53) mm Hg, (78.54±7.18) mm Hg, and (81.1±8.3) mm Hg, respectively at 30,60,90, and 120 minutes after the peritoneal ventilation with pure oxgen (all P < 0.05).Meanwhile PaCO2 was (63.84±9.09)mm Hg at baseline and (59.84±14.22) mm Hg, (59.16±15.5) mm Hg, (60.02±7.07) mm Hg, and (61.38± 6.56)mm Hg, respectively at 30,60,90, and 120 minutes after the peritoneal ventilation with pure oxgen with no significant change (P > 0.05).Conclusion Peritoneal ventilation can obviously improve hypoxaemia induced by mechanical controlled hypoventilation, whereas hypercapnia remains unchanged.

Exercise of walking which is regarded as a popular aerobic exercise,is receiving increasing attention in recent years,especially for primary and secondary prevention of cardiovascular diseases.But the guidelines and recommendations are based on low evidence levels,lack enough evidence-based support,and cannot provide individual exercise prescription for more specific populations and specific indications.Thus we put forward the concept of quantitative walking exercise,and hope further studies on relationship between walking exercise and chronic diseases so as to develop appropriate exercise prescriptions for prevention and rehabilitation of chronic diseases.

ObjectiveTo evaluate the Fuji intelligent chromo endoscopy (FICE) in the diagnosis of Barrett esophagus (BE).MethodsFrom September 2010 to March 2011,a total of 180 patients with suspected reflux esophagitis were examined successively by FICE,magnifying FICE,acetic dyeing endoscopy and magnifying acetic dyeing endoscopy.The diagnosis was made out under the observation of lesion extensions,superficial mucosa contrast ratio,pit patterns and capillary forms of BE.The endoscopic diagnosis was made and compared with the pathologic diagnosis,and the consistency of the diagnosis was evaluated by Kappa value.ResultsBE was confirmed in 35 patients ( 19.4％ ) pathologically.The consistency rates of diagnosis under FICE and acetic dyeing endoscopy were 81.7％ and 72.8％ ( P ＜ 0.05 ).The consistency rates of diagnosis under magnifying FICE and magnifying acetic dyeing endoscopy were 97.8％ and 85.6％,respectively (P ＜ 0.05).FICE magnifying endoscopy revealed better mucosal structures of capillaries than magnifying acetic dyeing endoscopy did ( P ＜ 0.05 ),but there was no significant difference in revealing of duct openings (P ＞ 0.05).The specificity,sensitivity,positive predictive value,negative predictive value and Kappa value of FICE in diagnosis of BE were 82.1％,80.0％,51.9％,94.4％ and 0.52,respectively,which were 73.2％,71.4％,39.1％,91.4％ and 0.34 of acetic dyeing endoscopy,98.6％,94.3％,94.3％,98.6％ and 0.93 of magnifying FICE,and 88.3％,74.3％,60.5％,93.4％ and 0.58 for magnifying acetic dyeing endoscopy.ConclusionAs a neotypical endoscopic system,magnifying FICE could exhibit clearly the pit patterns and microvascular structures of esophagus mucosa,and it can capture the optimal images of Barrett's epithelium.FICE could improve the diagnosis of BE in vivo.

ObjectiveTo evaluate Fuji intelligent color enhancement (FICE) chromoendoscopy for diagnosis of early gastric cancer. MethodsFrom February 2010 to March 2011 ,a total of 67 patients with suspected gastric mucosal lesions were enrolled in this study. The lesions were observed with magnifying endoscopy, FICE, magnifying chromoendoscopy and indigo-carmine-magnifying-chromoendoscopy.Suspected gastric mucosal pit patterns and microvascular morphology were compared. Targeted biopsy was performed on suspected locations. Sensitivity, specificity and pathological consistency were compared between the 3 procedures. ResultsOut of 67 patients, 17 were diagnosed as having early gastric cancer.There was no difference among magnifying endoscopy, FICE magnifying chromoendoscopy and indigo-carmine-magnifying-chromoendoscopy in pit pattern findings,however, FICE magnifying chromoendoscopy was superior to other 2 procedures in displaying capillary loop. The sensibility, specificity and pathological accordance rate of FICE magnifying chromoendoscopy were 94. 1％ ( 16/17 ), 98. 0％ (49/50) and 97.0％(65/67), which were higher than those of the magnifying endoscopy [58.8％ ( 10/17), 84％ (42/50)and 77.6％ ( 52/67 )] ( P ＜ 0. 05 ), and were not different from those of indigo-carmine-magnifying-chromoendoscopy [88.2％ (15/17), 96％ (48/50) and 94.0％ (63/67)] (P ＞0.05). Conclusion FICE magnifying chromoendoscopy provides rather clear images of gastric mucosa and intrapapillary capillary, thereby improving the accuracy of endoscopic biopsy and then imporving the diagnosis rate of early gastric cancer.
