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 investigate the preemptive analgesic effect of flurbiprofen on inflammatory cytokine in patients undergoing cerebral operation.Methods:Forty ASA Ⅰ-Ⅱpatients undergoing cerebral surgery were randomly divided into control group(group C,n=20)and flurbiprofen group(group F,n=20).Flurbipmfen of 10 mL was given intravenously 15 min before skin incision.The values of VAS scores were recorded at 2 h,24 h and 48 h after operation.Blood samples were taken for determination of serum levels of TNF-α,IL-6 and IL-10 immediately before induction of anesthesia(T1,baseline),at 2 h of operation (T2),immediately after the end of operation (T3) and 24 h after operation (T4).The parameters of anaesthesia time,hemorrhage volume,urine volume,transfusion volume and the dosage of remifentanil and propofol were recorded during the period of anaesthesia.Results:The VAS score was lower in group F than that in group C at 2 h and 24 h after operation (P＜0.05),but there was no difference at 48 h after operation between the two groups(P＞0.05).The dosages of remifentanil and propofol were lower during anaesthesia in group F than that in group C(P＜0.05).Compared with T1,TNF-α was significantly increased at T2 and T3 in both groups,and the peak value at T2 (P＜0.05).TNF-α was decreased at T2-T4 in group F than that in group C(P＜0.05).Compared with T1,the levels of IL-6 and IL-10 were significantly increased at T2-T4 in both groups,and the peak value at T3(P＜O.05).The value of IL-6 was decreased and the value of IL-10 was increased at T2-T4 in group F than those in group C (P＜0.05).Conclusion:Flurbiprofen was suitable as a preemptive analgesia and could suppress stress reaction of inflammatory in neurosurgery.

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.

Objective To investigate the effect of percutaneous transforaminal endoscopic surgery for lumbar prolapse upwards type disc herniation.Methods According to the digital table,90 patients with lumbar prolapse upwards type disc herniation were randomly divide into the observation group and the control group,45 cases in each group.The observation group was treated with percutaneous transforaminal endoscopic surgery,the control group was treated with conventional open surgery.The curative effect,operation and adverse reactions were compared between the two groups.Results All patients were satisfied with the location,and they were completely removed from the nucleus.Compared with the control group,the operation time[(75.3±23.1)min vs.(103.4±35.4)min]and hospitalization time[(6.8±1.2)d vs.(8.7±1.8)d]of the observation group were shorter,the bleeding volume[(24.5±8.5)mL vs.(51.6±12.7)mL]was lower,the differences were statistically significant(t=4.453,5.632,4.269,all P<0.05).After one month and three months,the VAS score[(2.53±0.65)pints and(1.33±0.48)points]and ODI[(21.40±5.04)% and(12.93±3.50)%]of the observation group were significantly lower,there were statistically differences between the two groups compared with those before treatment(t=6.755,8.765,all P<0.05).And after one month,the VAS score and ODI of the observation group were significantly lower than those of the control group,the differences were statistically significant(t=4.342,3.985,all P<0.05).There was no significant difference between the two groups in the excellent and good rate(86.7% vs.82.2%,X2=1.011,P>0.05).ConclusionPercutaneous endoscopic discectomy surgery in the treatment of lumbar prolapse upwards type disc herniation is reliable,and it has less trauma and shorter hospital stay.

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.

Mutations in isocitrate dehydrogenase are among the most common genetic alterations in intrahepatic cholangiocarcinoma (ICC).Mutant IDH proteins in ICC and other malignancies acquire an abnormal enzymatic activity, allowing the conversion of alpha-ketoglutarate (alphaKG) to 2-hydroxyglutarate (2HG), which inhibits the activity of multiple alphaKG-dependent dioxygenases, and results in alterations in cell differentiation and tumorigenesis.This review will focus on recent advances, which may help understand the function of IDH mutation in intrahepatic cholangiocarcinoma.

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3～5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.
