Inducing animal viruses to adapt to chicken embryos or chicken embryo fibroblasts(CEF)is a common method to develop attenuated live vaccines with full security.Canine distemper virus(CDV)also does this,but the mechanisms and particular receptors remain unclear.Virus overlay protein blot assays were carried out on CEF membrane proteins,which were extracted respectively with a Mem-PERTM kit,a radioimmunoprecipitation assay buffer or a modified co-immunoprecipitation method,and revealed a common 57 kDa positive band that differed from the 42-kDa positive band in Vero cells and also from those receptors reported in lymphocytes and293 cells,indicating a receptor diversity of CDV and the possibility of the 57-kDa protein acting as a receptor that is involved in adaptive infection of CDV Kunming strain to CEF.

Objective To study 3D imaging and pelvic angiography for multiple pelvic fracture. Methods 30 cases suspected with multiple pelvic fracture with vascular injury were performed with 3D imaging and pelvic angiography, whose dada were analyzed retrospectively. Results 30 cases had multiple pelvic fracture to different extents, of which 25 ones had no abnormality at lower part of abdominal aorta, left & right common iliac artery, left & right iliac artery, external iliac artery and upper part of left & right femoral artery, and 1 case, complicated with local hematoma, had a raptured left external iliac artery at the middle piece of the ilium, and another two cases, also complicated with local hematoma, had a raptured left iliac artery due to the comminuted fracture of the sacrum and a raptured right anterior femoral artery due to the fracture of light femur respectively. Conclusion 16-slice CT has to be involved in when the patient with multiple pelvic fracture is suspected with vasculaer injury.

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

Objective To evaluate the feasibility of histogram analysis of susceptible signal intensity in differentiating papillary (pRCC) from chromophobe renal cell carcinoma(ChRCC). Methods Thirteen cases with pRCC and 9 cases with ChRCC, who underwent susceptible-weighted imaging(SWI), MR common scanning and enhancement, were assessed retrospectively. The histogram parameters of susceptible signal intensity were measured, including maximum, minimum, mean, median, skewness and kurtosis. The independent samples t test(normal distribution) and Mann-Whitney rank sum test(skewed distribution) were used to compare the differences in SWI parameters between pRCCs and ChRCCs. Receiver operating characteristic curve was used to evaluate the efficiency of the whole-tumor SWI parameters in differentiating pRCCs from ChRCCs. Results The significant differences of the minimum, mean, median and skewness between pRCCs and ChRCCs were present(P<0.05), and there was no significant differences in maximum and kurtosis between between pRCCs and ChRCCs(P>0.05). In all the histogram parameters, the area of ROC curve of mean value was largest(0.80). The sensitivity of minimum value (84.62%) was the highest and and the specificity of skewness(100.00%) was the highest. Conclusion Histogram analysis of susceptible signal intensity can help differentiate pRCCs from ChRCCs.
