Objective To study the role of chromoendoscopy with toluidine blue to diagnose gastric cancer and precancerous change.Methods572 cases were randomized into two groups.288 cases in testing group took gastroscopy with 0.1% toluidine blue sprinkles,while ordinary gastroscopy was applied in 284 cases of control group.We took biopsy in all of those cases for pathology examination.The biopsy was taken from heterochrome area if heterochrome area appeared in testing group,otherwise from suspected affection.ResultsDetection rate of gastric cancer of test groups(9.72%)was higher than that of control groups(5.28%).Both of the methods were significantly different(P

The addition of long-term noninvasive positive pressure ventilation (NPPV) to a pulmonary rehabilitation (PR) program in stable patients with advanced chronic obstructive pulmonary disease (COPD) can enhance the effects of PR, continuely improve exercise tolerance and dyspnea, stabilize pulmonary function, enhance health-related quality of life. Moreover, it maybe improve the prognosis of the patients with COPD. This article introduced the implement of the combination of PR and NPPV in stable patients with advanced COPD.

Objective: To optimize the allocation scheme of military medical equipments based on the characteristics of modern war and the progression of the military medical equipment of People's Liberation Army (PLA). Methods: Aiming to optimize the allocation of military medical equipment, we designed the integrated framework of the allocation system and analyzed the need of optimized allocation. Using the linear programming and queuing theory, we established the optimized allocation models for both medical treatment equipments and evacuation equipments. Results: Based on the health service characteristics of military medical equipments, the optimized allocation models for medical treatment equipments and evacuation equipments were successfully established. The application of the established models was studied in the medical service station of the division level. Conclusion: The optimized allocation scheme of military medical equipment has been proposed in the present study, which provides evidence for decision-making on the future development of military medical equipments of PLA.

Objective To establish the quality standard of Fufang-Shiwu-Zhixue powder. Methods The microscopical identification was adopted to analyze charred typha pollen and cuttlebone. TLC was used to identity rhubarb and radix notoginseng. UV-HPLC was used to determine the contents of notoginsenosides R1, ginsenosides Rg 1, ginsenosides Rb1. Results Microscopic identifications shower the characteristics of harred typha pollen and cuttlebone. The identified characteristics of rhubarb and radix notoginseng by TLC were distinct and the spots were clear. Notoginsenosides R1, ginsenosides Rg 1, ginsenosides Rb1 showed good linearity in the range of 0.16-1.58 μg (r=0.9998), 0.58-5.81 μg (r=0.9999), 0.33-3.29 μg (r=1.0000), respervtively.The average recoveries were 98.51% (RSD=1.81%), 97.80% (RSD=2.04%), 98.22%(RSD=1.45%). Conclusions The method is accurate, simple and repeatable, which could be used for the quality control of Fufang-Shiwu-Zhixue powder.

Objective To establish the quality control ofBaiduyin syrup.Methods The TLC was used to identity Radix paeoniae rubra, Radix Scutellariae. The quantitative determination of baicalin and buddleoside was completed by HPLC.Results The spots on TLC plates were distinct and high resolution. Compared with the negative samples, the contrast medicinal materials or control products showed that there were no spots of the same color in the corresponding position. The linear ranges of baicalin and buddleoside were 0.2179-2.1790 μg (r2=0.999 9), 0.1319-1.3190 μg (r2=0.999 7). TheRSD were 1.51% and 2.01%. Conclusions The established quality control method is simple, accurate and reproducible, which can be used for the quality control ofBaiduyin syrup.

Objective To compare the safety and efficacy of ibutilide and amiodarone in converting post-coronary artery bypass grafting (CABG) new-onset atrial fibrillation (AF) to sinus rhythm. Methods This study was a prospective, singleblinded, randomized clinical trial. Totally 100 patients who met the inclusion criteria were enrolled and were intravenously treated with ibutilide (group A) or amiodarone (group B). In group A, Ibutilide was administered at a dose of 1 mg in 10 min, which was repeated after an interval of another 10 min if the arrhythmia was not converted; ibutilide was not given anymore no matter the conversion was achieved or not. In group B, amiodarone was administered at a dose of 5 mg/kg for the first 30 min, followed by 1 200 mg in the next 24 h; amiodarone was not given anymore no matter the conversion was achieved or not. Immediate conversion rate, conversion time and post-operative recurrence rate within 30 days were compared between the two groups. Results No severe adverse reactions were observed in both groups. The immediate conversion rate of group A was significantly higher than that of group B (82% vs 58% , P<0.01) , and the conversion time was significantly shorter than that of group B (66 min vs 660 min, P<0.01). The post-operative recurrence rates were not significantly different between the two groups within 30 days after operation (7.3% vs 6.9%, P>0.05). Conclusion Ibutilide and amiodarone are both safe in converting post-CABG new-onset AF to sinus rhythm, and ibutilide is more effective, more rapid in functioning and with a higher efficacy.

Objective: To develop a novel regulable sutureless aortic arch prosthesis and to apply it in an animal experimental study. Methods: The arch skeleton of the prosthesis was made of tandem Z-shape NiTiNOL wire; the branch skeleton was made of laser-cut NiTiNOL tube; and the whole skeleton was coated with thin ePTFE film. The blood vessel was anastomosed by direct ligature, needing no manual suturing. The prosthesis was applied in swine aortic arch operations under the bypass condition. The practicality for surgery and the feasibility of anastomosis of the prosthesis were assessed. Results: Aortic arch operations were successfully performed in 6 of the 8 experimental animals. The prostheses were easy to use, and the mean bypass time was only 10 min. The blood loss of the anastomoses was less than 100 ml within 8 h postoperatively in 5 animals; one had more blood loss due to prosthesis mismatch. Conclusion: The novel regulable sutureless aortic arch prosthesis has satisfactory practicality for surgery and reliable anastomosis, making it promising in future clinical application.
