With the development of coronary artery recanalization technology,more and more attention are paid to myocardial ischemia-reperfusion injury.PPAR-? is distributed in rat myocardium.Besides insulin sensitizing effect,the ligands of PPAR-? can also exert its protective effects by inhibiting cell inflammatory response and apoptosis.In this review,the author summarized the research advances of the protective effects of the ligands PPAR-? on myocardial ischemia-reperfusion injury.

Objective To investigate the effect of different anesthesia methods on perioperative body temperature. Methods Eighty patients undergoing esophagus cancer resection were randomized into two groups of combined general and epidural anesthesia(GEA, group A,42 cases) and general anesthesia(GA, group B, 38 cases). Epipharynx and peripheral temperatures were recorded at the same time every 30 minutes for 3 hours after induction. Epipharynx temperature was recorded than after when circulating water mattresses and fluid warming were used to rewarming. The incidence of postoperative shivering was recorded. Results The peripheral temperature was gradually decreased after induction in both groups. The core temperature was decreased quickly within the first 1 hour in both groups, which was reduced slowly within the next two hours with a greater magnitude of temperature reduction in group A than that in group B(P<0.05). The incidence of shivering was higher in group A than that in group B during warming up. Conclusion The patients undergoing long procedures such as esophagus cancer recection under GEA is at more risk for hypothermia than those under GA.

Objective: To observe the effect of home-made blenderized diet on nutritional support in old comatose patients.Methods: Sixty-three old comatose patients were fed with home-made blenderized diet by nosal gastric feeding.Triceps skinfolds were measured every month.The serum levels of albumin,pre-albumin,total number of lymph cells and hemoglobin were analysed every month.Results: No side effects of abdominal pain,dearrhea,nausea and vomiting were observed in the fed patients.The states of nutrition(such as triceps skinfolds,albumin,pre-albumin,total number of lymph cells and hemoglobin) were improved significantly after home-made blenderized diet.Conclusion: The home-made blenderized diet can support the old comatose patients effectively.

With the review of medical video network transmission technology,this paper mainly analyzes the characteristics of medical video transmission,the distinctiveness of network transmission environment in hospitals and the clinical request coming from the doctor's working in the operating room.A medical video communication technology is proposed that can really meet the clinical request.

Objective To develop an ELISA for detection of anti-dsDNA antibody by using plasmid DNA as antigen.Methods DNA in plasmid pBV220 for prokaryotic expression vector was purified by base-cleavage. The microtiterplates were pretreated by poly-L-lysine and coated by the plasmid DNA in a dilution of 1∶50 as antigen. An ELISA method for detection of serum anti-dsDNA antibodies was developed with HRP-SPA as enzyme-labeled marker.The IIF using crithidia lucilia as substrate was performed simultaneously for comparison. The serum samples from 64 patients with SLE, 8 with MCTD and 17 with RA were detected. Results The concentration of DNA was 1 54 g/L by UV spectrophotometer at wavelength of 260 nm. The positive percentage of ELISA for anti-dsDNA was higher than that of IIF. By comparison with IIF the positive percentages in SLE, MCTD and RA groups were 23 4% vs 17 2%, 12 5% vs 12 5% and 11 8% vs 5 9%, respectively, and the coincident rates between the 2 methods were 93 8%, 100% and 94 1% respectively. The sensitivity and specificity of the developed ELISA for detection of anti-dsDNA were 100% and 93 4% when IIF was as gold standard.Conclusion The ELISA by using plasmid DNA as antigen to detect anti-dsDNA has fine precision, sensitivity and specificity. Its positive rate is higher than that of IIF thus it will contribute to monitor the activities for SLE patients′ condition.

Traditional tele-consultation platform adopts point-point communication.With the development of internet communication and dynamic service page technology,the data transmission of medical images through internet becomes possible.This paper discusses the system structure of remote medical images consultation platform based on internet communication and analyzes the data management and communication mode adopting international ACR-INDEX medical image code.

XML dynamic swapper of network data applied, a network management platform for medial equipment maintenance is developed, which is based on hospital LAN communication. J2EE-based multiplayer B/S structure is adopted. With the platform, routine management, malfunction declaration, maintenance service and data totaling can be carried out effectively.

Objective To explore the role of case based learning (CBL)on Otolaryngology-Head and Neck Surgery teaching. Methods First, correct and high-quailty teaching case was selected. Then, reasonable and precise question was edited. All students needed to prepare their lessons before class and were encouraged to ask question or answer question. And some warnings should be noticed. Result After CBL being implemented, the students received higher clinical grades and more clinical skills. They were more likely to retain their initial interest in or switch their preference to careers in otolaryngology. The supervisor highly appreciated our teaching. Conclusion CBL is feasible in Otolaryngology-Head and Neck Surgery teaching and it should be applied more in future.

nclude positive vascular remodeling,low plaque density,spotty calcification,and eccentric stenosis.

Objective To explore time difference attack therapy in Acinetobacter bauamnnii infection. Methods 67 patients with Acinetobacter bauamnnii were divided into two groups. The experimental group were first given Fosfomycin 4 g 5% GS 100 ml iv girt to finish within 60 min and then given Cefperazone/Sulbactam 4 g 0.9% NS 250 ml iv gitt immediately bid. The control group were given: Ampicillin/Sulbactam 3 g 0.9% NS 250 ml iv gitt (tid) + Ciprofloxacin 0.2 g iv girt (bid). The treatment course all was 11 days. Results The overall effective rate of experimental group methods was superior to that of control group(X2 =9.56 ,P =0. 023). Conclusion The Fos-fomycin Cefperazone/Sulbactam time difference attack therapy for the treatment of Acinetobacter the bauamnnii in-fection is a new way.
