ObjectiveTo determine the possibility of r eal-time perfusion imaging in the quantitative evaluation of myocardial perfusion in various segments of left ventricle. MethodsImages of ten anesthetized dogs were obtained at the mid-papillary muscle short-axis view with a real-time imaging system. Mechanical index (MI) was adjusted to 0.1 , 0.2 and 0.4 respectively, and frame rate was set at 20 Hz. Optison was infused intravenously at a rate of 0.1 , 0.2 and 0.5 ml/min, respectively. Images were recorded for 150 real-time frames commencing immediately after a couple of Doppler bursts. Myocardial opacification was assessed both visually and quantitatively for six segments of left ventricle (antero- and infero-septum, inferior, posterior, lateral and anterior wall). Myocardial signal intensity versus real-time frame curves were made and fitted to an exponential function: Y=A(1-e -?t ). ResultsUsing low MI (MI= 0.1 or 0.2 ) and with continuously infusion of Optison at a rate of 0.2 or 0.5 ml/min, real-time imaging resulted in sufficient myocardial opacification and left ventricular endocardial border definition, and displayed myocardial thickening and wall motion simultaneously. ConclusionsReal-time imaging has a potential in the quantitative assessment of myocardial perfusion, and allows simultaneous assessment of perfusion and myocardial function.

BACKGROUND:5-Fluorouracil occupies an important position in the treatment of gastric cancer, but its long-term use can easily induce adverse reactions such as myelosuppression and leukopenia. Polylactic acid and its copolymers have a higher biocompatibility, and their decomposer cannot gather in the body.
OBJECTIVE:To investigate the in vitro cytotoxicity mechanism of 5-fluorouracil-loaded polylactic acid nanoparticles on gastric cancer cel lines.
METHODS:Ten mice were selected in this study. 5-fluorouracil-loaded polylactic acid nanoparticles (1×10-7, 1×10-6, 1×10-5, 1×10-4 mol/L) were prepared using ultrasonic emulsification method. Kiling effect of polylactic acid nanoparticles on gastric cancer cel lines in vitrowere detected. Then, the inhibition rate was calculated at different concentrations.
RESULTS AND CONCLUSIONS: Under the transmission electron microscope, 5-fluorouracil-loaded polylactic acid nanoparticles had good shape and relatively evenly distributed with no adhesions. After drug administration, the drug concentration was 50% at 24 hours and 62.9% at 72 hours. After 48 hours co-culture with single 5-fluorouracil or 5-fluorouracil-loaded polylactic acid nanoparticles, the viability of gastric cancer cels showed a decrease trend with the increase of drug concentrations, and moreover, 5-fluorouracil-loaded polylactic acid nanoparticles had a better cel inhibition ability than the single 5-fluorouracil (P < 0.05). The IC50value of 5-fluorouracil-loaded polylactic acid nanoparticles was significantly lower than that of 5-fluorouracil (P < 0.05). These findings indicate that polylactic acid nanoparticles as good drug carriers have a strong drug loading capacity and increase drug concentration in the body, but cannot reduce the biological activity of 5-fluorouracil, which provide new ideas for the treatment of gastric cancer.

AIM: To detect the changes of inducible nitric oxide synthase (iNOS) expression in kidney following ischemia-reperfusion(I-R)of hindlimbs and to elucidate their significance. METHODS: I-R was established using the occlusion of the femoral arteries for 4 h and re-opening for 2-24 h in rats. The expression of iNOS mRNA,and iNOS protein and the nitrotyrosine (NT),a marker of peroxynitrite (ONOO -),in renal tissue were detected with reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical technique,respectively. The superoxide dismutase (SOD) activity and malondialdehyde (MDA) contents in renal tissue were spectraphotometrically measured. The observation of pathologic changes of renal tissue was made following the inhibition of iNOS by aminoguanidine (AG). RESULTS: Compared with control group,the relative expression level of iNOS mRNA significantly increased in I-R group. There were more iNOS and more NT positive product in the epithelial cells of renal proximal convoluted tubules and thick segments of Henle′ loops in I-R group than control group. The contents of MDA markedly increased,while the activity of SOD significantly decreased in I-R group,compared to those in the control groups. The pathologic changes of kidney became milder in I-R group following the inhibition of iNOS by AG. CONCLUSION: The expression of iNOS mRNA and protein in renal tissue were significantly upregulated,excess induction of NO contributed to the kidney injury during the I-R of hindlimbs.
