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: The main objective of this research paper is to analyze the research focus and trend in the health policy and services between 2010 and 2016, with a view to providing a reference for the research on health policy and service in China to tackle a number of challenges and opportunities for future studies.Methods: This article retrieved English literature about the Health Policy & Services from the Web of Science (2010-2016), and analyzed the records with Citespace by general analysis, word frequency and centrality.Results: A total of 22,716 articles were obtained.The three keywords with the highest frequency of word frequency were: care, quality of life and healthcare, and Quality of life had the highest centrality.Keywords could be divided into five clusters: health measurement;health factor;health intervention;medical insurance;health intervention evaluation.Conclusions: Foreign health policy research focused on health and health care;focusing on measuring the impact of health outcomes;and committed to improving the health and quality of life of the population.

Objective To investigate the efficacy of acupoint selection at distant places and local tenderness points in treating migraine without aura.Method Sixty patients were randomly allocated, using a random number table, to two groups, 30 cases each. The treatment group received acupuncture at distant points selected along meridians and local tenderness points and the control group, acupuncture at conventionally selected points. The therapeutic effects were evaluated using the visual analogue scale (VAS) and the short-form McGill Pain Questionnaire (SF-MPQ).Result After treatment, the VAS pain score was lower in the treatment group than in the control group; there was a statistically significant difference (P<0.05). The total efficacy rate was 93.3% in the treatment group and 73.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Both acupuncture at distant points selected along meridians and local tenderness points and acupuncture at conventionally selected points have a certain therapeutic effect on migraine, but the former produces a better effect than the later and can markedly relieve the pain and improve the quality of life in the patients. The outcome of this study provides a certain reference value for clinical treatment of this disease.

Objective To study expression differences of the ataxia telangiectasia mutated (ATM ) protein in early esophageal squamous cell carcinoma tissues and adjacent normal tissues in order to explore its diagnostic significance for early esophageal squa-mous cell carcinoma .Methods ATM protein expression was detected in early esophageal squamous cell carcinoma tissues and adja-cent normal tissues by immunohistochemical SP method and the differential expression was calculated by using statistical methods . Results The positive positive expression rate of ATM protein in the early esophageal squamous cell carcinoma tissue and adjacent normal tissue were 65% and 95% respectively ,which were statistically different (P= 0 .044) .Conclusion The ATM protein ex-pression in esophageal squamous cell carcinoma tissue declined .The detection of ATM protein in esophageal squamous cell carcino-ma tissue could become a reliable method for early diagnose of esophageal squamous cell carcinoma .

Objective To investigate the feasibility of using a new type carina type tracheal prosthesis made of complex material to replace trachea and carina defects. Methods According to biomechanics index, a new carina type tracheal prosthesis was designed and constituted with carbon fiber and silicon. 19 dogs were divided into two groups randomly: group A(n=11), the carina type tracheal prosthesis anastomosed directly to dog′s trachea and bronchus;group B(n=8), based on group A, meanwhile the diaphragm was incised and the pedicel caul was transplanted from abdominal cavity to thorax to enwrap the carina type tracheal prosthesis and anastomotic site. Results The average survival period post operation in group A and group B were (3.462?1.849)d and (6.475?1.062)d ,respectively. There was significant difference of the survival period between two groups(P

Nonalcoholic fatty liver disease (NAFLD) is a clinicopathological syndrome caused by liver damage factors except alcohol and has the major feature of diffuse macrovesicular hepatocyte steatosis.Thetwo-hit hypothesis can partly explain the pathogenesis of NAFLD.Recent studies have found that ceramide is a key molecular messenger involved in the development and progression of NAFLD,and as a sphingolipid,it is closely associated with the two-hit hypothesis.This article reviews the role of ceramide in NAFLD.
