Journal of Chongqing Medical University 1986;0(04):-
Objective:To investigate the effect of simvastatin on cardiomyocyte apoptosis and cardiac dysfuction after myocardial infarction.Method:Simvastatin was administrated to the rats with myocardial infarction which was modeled by left anterior descending coronary artery ligation. After 7days, the apoptotic myocyte cells were quantified by TUNEL staining;left ventricular function index was measured by echocardiography and the level of serum lipid was measured by biochemical method.Results:Compared with infarction group, apoptotic myocyte cells in simvastatin group significantly decreased in infarction zone,border zone and non-infarction zone(P0.05).Conclusion:Simvastatin inhibits cardiomyocyte apoptosis and improves cardiac function after myocardial infarction.

Journal of Interventional Radiology 2001;0(05):-
Arterioportal shunt often occurs in hepatocellular carcinoma of advanced stage, with obvious decrease of the survival rate. The proper management of arterioportal shunt correlates directly with patient's prognosis. This comprehansive article reviews the interventional management of arterioportal shunt for hepatic carcinoma from literatures during recent years. (J Intervent Radiol, 2006, 15: 312-314)

Injection Stauntoniae (IS ) was applied ou a part of the saphenous nerve of rat 4mm in length. With 50% IS, amplitudes of A??, A? and C components of the compound action polential were reduced and their latencics were delayed. In particular, the amplitudcs of A? and C components reduced to 47.0% ? 23.o% and 44.0?20.0% (MEAN?SD, n = 8, P

To investigate the prevalence and the antibiotic resistance of bacteria isolated from 25 miniature pigs. 45 bacterial strains were isolated, which were identified by biochemical assays, amplification of 16S rRNA genes by PCR and sequence analysis, and were evaluated for resistance to 30 antibiotics. The identification results showed that these bacteria belonged to Campylobacter (Campylobacter jejuni), Helicobacterium (Helicobacter pylori), Klebsiella (Klebsiella pneumoniae), Escherichia (Escherichia coli, Escherichia fergusonii), Pseudomonas (Pseudomonas aeruginosa), Stenotrophomonas (Stenotrophomonas maltophilia), Staphylococcus (Staphylococcus aureus, Staphylococcus haemolyticus, Staphylococcus simulans), Streptococcus (Streptococcus pneumoniae, Streptococcus suis, Streptococcus vestibularis, Streptococcus mitis, Gemella measles, Aerococcus viridans) and Bacillus (Bacillus subtilis, Bacillus licheniformis, Bacillus alvei, Bacterium megaterium). These bacteria were all susceptible to aztreonam and cephalothin. However, the resistence to furazolidone was found. Microbial population carried by miniature pigs in China had characters of diversity. Results of this study provided scientifical accordance for the microorganism monitoring of miniature pigs in China.

Objective: To study the application of CT and MRI fusion technique in the diagnosis and treatment of intraocular and orbital tumors. Methods: 2D-images of 13 patients with intraocular and orbital tumors were fused by special-point registration and Iterative Local Closest Point(ILCP) method; 3D-fusion images were reconstructed by Ray Tracing method. Results: A 3D-CT-MRI fusion images of intraocular and orbital tumors were reconstructed and displayed. The CT and MRI data of intraocular and orbital tumors were displayed on the same image as a comprehensive whole,which provided a stereogram of 3D-structure of the normal and abnormal orbital tissues. Anatomical structure of the orbit was clearly visualized by 3D-CT-MRI image. Conclusion: The multi-modality fusion technique can provide more accurate and comprehensive information for clinical diagnosis of intraocular and orbital tumors, which is helpful for doctors' planning of surgical operations,clinical education and doctor-patient communication.

Objective The questionaires of the ONFH aegers who were hospitalized in Kanggu hospital,during 2005-2008 ,were collect-ed to evaluate the therapeutic effects of acupotomy by proper statistical methods. Methods Four indexes according to the criteria of Therapeutic effect of adult ONFH recovery and reconstruction (ZHAO Dewei, 1996) were measured to evaluate the effect of the treatment. Results Monofac-torial analysis showed that the treatrnent was effective,but some phenomena could not be correctly explined in specialized field. This problem was re-solved appropriately by structural equation model(SEM). Conclusion By the method of SEM, the confounding factors could be better controlled and the evaluation was more reliable.

AIM To test the hypothesis that intravenous liposomal prostaglandin E 1 (Lipo PGE 1) would attenuate reperfusion injury in a rabbit ischemia reperfusion model. METHODS Twenty four open chest rabbits were randomized to receive a 10 minute intravenous infusion of either liposome diluent (placebo), free PGE 1 (2 ?g?kg -1 ), or Lipo PGE 1(2 ?g?kg -1 PGE 1) after 60 minutes of left anterior desending (LAD) ligation just before reperfusion. Carotid arterial pressure and electrocardiogram were monitored and recorded continously throughout the whole experiment. After 2 hours reperfusion, infarct size and region at risk were measured by postmortem dual dyes with triphenyl tetrazolium chloride (TTC) and Evans blue. Myocardial leukocyte infiltration by myeloperoxidase (MPO) assay was performed. RESULTS Infarct size as a ratio of weight of infarcted tissue to weight of region at risk (MI/RISK) was significantly reduced with Lipo PGE 1 32.20%?4.70% compared with PGE 1 42.09%?6.93% or placebo 44.57%?5.46% ( P

Objective To Investigate the factors affecting the post treatment fever in patients with primary liver cancer (PLC) undergone transcatheter arterial chemo embolization(TACE).Methods Seventeen clinical parameters of 102 TACE procedures were determined as independent variables, while the numbers of days running a fever after the procedure of the patients were determined as dependent variables. A multivariate stepwise regression analysis was performed to determine the factors that had affected the duration of fever. Results The factors that affected the fever after TACE were the dose of lipiodol used, ascites, using gelatin sponge(GS), serum albumin level, a history of fever, pre operative leukocyte counts and age. The volume of lipiodol used had played the most important role in affecting febrile time. Conclusions The amount of lipiodol used is the most important factor affecting the post treatment fever in patients with PLC undergone TACE with a tendency of intensification by using GS. The systemic state and the regional state of the liver before the treatments also play some parts in affecting the fever. Some frbrile cases are probably associated with potential infection. The lasting time of fever can be predicted approximately by building up a multivariate regresion equation.
