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.

Bacterial infection is frequently seen in patients with liver cirrhosis,and the most common type of bacterial infection is spontaneous bacterial peritonitis (SBP).In clinical practice,antibacterial agents are widely used in the treatment of SBP.In addition,antibacterial agents can reduce rebleeding and mortality rates in patients with upper gastrointestinal bleeding.However,in order to avoid bacterial resistance,the appropriate use of antibacterial agents is very important.This article reviews the indications and resistance of antibacterial agents in patients with liver cirrhosis.

Glucose-6-Phosphatase (G6Pase) was regarded as a marker enzyme of the endoplasmic reticulum in a number of different cells. The purpose of this report is to study the localization of G6Pase activity in the rat left ventricular myocardial cells. G6Pase activity was found in the lumen of the nuclear envelope, the sarcoplasmic reticulum(SR) and the subsarcolemmal cisterns. The SR tubules between the adjacent myofibrils displayed characteristic distribution on their longitudinal profiles, as a curtain-like network, the tubules appeared to be tight network facing A-band, whereas tubules formed large polygonal meshes facing I-band. It is thought that the SR tubules facing A- and I-bands, respectively, represented an adaptation of SR to the selective shortening of the myofibrils at the I-band during contraction.

Left ventricular myocardial hypertrophy was produced in the rats by ligation of the abdominal aorta below the diaphragm for seven weeks.Ultrastructurally, it was observed that the nucleus and nucleolus were enlarged, and the density of the chromatin of the hypertrophied myocardial cells was decreased. Free ribosomes and endoplasmic reticulum were increased. Golgi apparatus was well developed and was increased in number.Cytochemically, G6Pase activity was localized in the lumen of the sarcoplasmic reticulum, nuclear envelope and subsarcolemmal cisterns, and it was also positive in the regenerative rough endoplasmic reticulum. TPPase activity appeared in the Golgi apparatus, and it was especially prominent in the Golgi apparatus of the hypertrophied cells.These findings suggest that the protein synthetic activity was increased in the hypertrophied myocardial cells.
