Objective To examine the effect of endotoxin on myocardial lipid metabolism and determine it′s possible mechanism Methods Sixty nine male Wistar rats (350 450g) were randomly divided into 2 groups: in vivo group and in vitro group In in vivo group endotoxin 0 1?g?kg -1 (small dose)or 1mg?kg -1 (large dose) was injected intrabdominally 3h after endotoxin administration the animals were anesthetized Heart was excised and passively perfused in a Laugendorff apparatus with oxygenated Krebs Heuseleit buffer at 37℃ Non esterified fatty acids (NEFA)and triacylglycerols(TAG) were used as energy supplying substance when the isolated heart had been stabilized for 15min NEFA or TAG was slowly added to the perfusate circuit 1 ml of perfusate was drawn every 10 min until the end of experiment (80 min ) for determination of the effects of endotoxin on NEFA or TAG oxidation and utilization by isolated heart At the end of experiment heart was harvested and frozen for measurement of myocardial lipids and lipoprotein lipase activity In in vitro group endotoxin was added to perfusate (1mg/ml) after the heart was excised and passively perfused In control group endotoxin was replaced by normal saline Results Large dose of endotoxin administered in vivo decreased NEFA oxidation rate by 30% in perfused isolated heart and caused increased accumulation of lipid in myocardial tissue By contrast endotoxin administered in vitro increased oxidation rate of TAG accompanied by an increase in myocardial lipoprotein lipase activity Administration of endotoxin in vivo and in vitro also caused accumulation of various exogenous lipids in myocardium in both NEFA and TAG perfused heart Conclusions This study shows that endotoxin has a significant effect on myocardial lipid metabolism The effect of endotoxin could be either direct or indirect according to the different lipids available

Objective To investigate the clinical significance of PET-CT to diagnose breast cancer and the axiUary lymph nodes metastasis. Methods 40 patients with breast cancer performed PET-CT were enrolled in the research. Qualitation the primary tumor and accuracy of PET-CT were evaluated on pathological results and compared with axillary lymph nodes dissection. To analyzed the concordance of the size of primary tumor on pathological result with B-mode ultrasonic and PET-CT and the correlation with the SUV. Results The accuracy, sensitivity and specificity of PET-CT in identifying breast cancer were 95%, 94%, 100%. The accuracy, sensitivity and specificity of PET-CT based on the situation of the axillary lymph node dissection were 88.2% 89.2% 83.3%. A significant association was found between tumor weiweihong and PET-CT, furthermore it had not association with SUV. Conclusion The diagnosis of PET-CT in identifying breast cancer and the axillary lymph node metastasis basically conforms to pathology. It possesses high sensitivity and specificity especially in identifying the size of the primary lesion. It offers a beneficial method to determine the axillary lymph node dissection and reasonable therapeutic regimen.

Objective To investigate the value of integrated PET-CT with 18F-FDG in the diagnosis of non-small cell lung cancer.Methods 91 patients with non-small-cell lung cancer(NSCLC)and 10patients with benign disease underwent integrated PET-CT from February 2004 to May 2005.Other diagnostic procedures were analysed. Results 91 patients with lung cancer were found by positive SUV and pathologically confirmed.Of the 10 patients with benign disease.positive SUV were found in 3 cases.2 cases with tuberculosis and 1 case with inflammatory pseudotumor were confirmed.Negative SUV were found in 7cases.1 case was incorrectly diagnosed by integrated PET-CT.The sensitivity,specificity and accuracy of integrated PET-CT in the diagnosis of NSCLC were 100%,90%,99%,respectively.Forty-eight of 91patients with lung cancer underwent operation.There were 30 cases with and 18 cases without mediastinal nodal metastases.There were two false negative cases and one false positive case.The sensitivity,specificity and accuracy of integrated PET-CT in the diagnosis mediastinal nodal metastases were 93.3%,94.4%,93.8%.respectively.Metastases were identified in 33 cases.Conclusion Functional metabolism and anatomy imaging are fused in integrated PET-CT.The primary site and metastases lesion are correctly diagnosed by integrated PET-CT.The accuracy of integrated PET-CT in the diagnosis of NSCLC is over 90%.

ObJective To locate the cysteine-rich domains(CRD) of murine 4-1BB binding to its natural ligand. Methods A serial soluble extracellular CRDs of routine 4-1BB and 4-1BBL fusion proteins was constructed and prepared. The binding of purified 4-1BB-Igs to 4-1BBL and 4-1BB monoclonal antibody were tested using ELISA assay and Western blot analysis. Blocking experiment with 4-1BBL and 4-1BB mon-oclonal antibody was performed by ELISA assay. Results All truncated overlapped proteins containing ex-tracellular CRD Ⅱ of murine 4-1BB were able to bind to 4-1BBL by ELISA assay, excepting the CRD Ⅰ do-main alone. A 4-1BB monoclonal antibody proved to block the interaction of 4-1BB and 4-1BBI, was also able to bind to CRD Ⅱ. Conclusion Murine 4-1BBL whose specificity was mapped to CRD Ⅱ of 4-1BB ex-tracellular region with a possible conformational structure.

We investigate the different expression of toxin gene mazF3,6,9 and antitoxin gene mazE3,6,9 in the drug-resistance Mycobacterium tuberculosis,we used quantitative real-time polymerase chin reaction method to detect the expression level of toxin gene mazF3,6,9 and antitoxin gene mazE3,6,9 in M.tuberculosis (20 mono-resistance strains,20 multidrug resistance strains and standard strain H37Rv).The differences of gene expression levels between groups were analyzed by oneway ANOVA.Contrasting with control group,toxin genes mazF6,9 were up-regulated expression levels both in mono-resistance (11.1519±22.31721;8.4306±17.97897) and multidrug resistance (4.6016±1.29018;6.9627±6.92948),had statistical significance (P＜0.01),mazF3 expression levels had statistical significance neither in mono-resistance nor in multidrug resistance (P＞0.05);antitoxin genes mazE3 was in down-expression level,and had statistical significance both in mono-resistance (0.3606±0.12527) and multidrug resistance (0.2016±0.16542) (P＜0.01),mazE6 had no statistical significance (P＞0.05)either in mono-resistance or multi drug resistance,mazE9 only in multidrug resistance(0.3989±0.37679) was in downexpression level,and has statistical significance (P＜0.001).The toxin gene mazF6,9 and antitoxin gene mazE3,9 may participate in the drug-resistance formation of M.tuberculosis.

AIM: To investigate the influence of GM-CSF on human vascular endothelial cells induced to form new blood vessels and the role of VEGF.METHODS: HUVECs were cultured by Matrigel to set up a stable angiogenesis system with the stimulating factors.The rhGM-CSF concentration-dependent and time-dependent effects and the role of VEGF165 were detected.CD34 was measured by immunochemical staining and numbers of vessel formation was calculated under microscopic observation.RESULTS: After treatment with rhGM-CSF at various concentrations and at different time points,the numbers of vessel formation increased in a dose-dependent and time-dependent manner.In the presence of VEGF165,the numbers of vessel formation increased evidently.CONCLUSION: HUVECs were induced to develop tubular structure in vitro cultured with Matrigel.GM-CSF promotes human vascular endothelial cells to form vessel-like structure in vitro in a dose-dependent and time-dependent manner.VEGF also in vitro promotes human vascular endothelial cells to form new vessel-like structure.
