Objective To explore the effect of osteopontin(OPN) as marker in colon cancer tissue and analyze the relationship between osteopontin and recurrence.Methods ELISA method was used to determine the serum levels of osteopontin in 58 patients with colon cancer(observation group) and 22 cases of normal subjects(control group);semi-quantity RT-PCR was used to detect the expression of osteopontin in tissues.The expression level of OPN mRNA in colon cancer tissue and serum OPN level in 23 recurrence cases and 35 non-recurrence cases one year after operation were observed.Results The OPN mRNA expression in colon cancer tissue and the serum osteopontin level in patients in observation group were higher than those in control group(P

Objective To review the various imaging modalities and their appropriate applications in the preoperative evaluation of both donors and recipients in liver transplantation (LT). Methods All the relevant literatures were reviewed. Different kinds of imaging modalities have been used in potential LT donors and recipients to assess the volume, the parenchyma and the vasculature of the liver, the biliary system, and the extrahepatic region of the upper abdomen and beyond. The techniques, the imaging findings, and the merits and shortcomings of various imaging modalities were presented.Results Traditional imaging techniques are still of valuable, while CT can provide rich and accurate information. "One-stop" comprehensive MR examination is emerging as the method of choice for the preoperative evaluation LT recipients and donors. Conclusion Each imaging method has its merits and limitations. Those imaging methods which can provide accurate and comprehensive information are likely to have better application future.

Objective To approach rehabilitation nursing measures in using the allogeneic ten-don to re-establish the anterior cruciate ligament of knee through the tibia twin tunnel under arthroscopy.Methods Mental nursing and direct functional exercises was given to 30 patients who received this kind of operation from November,2006 to July,2007,and functional exercises of flection and extention of knee joint by steps,functional exercises of muscle force of quadficeps muscle and back muscle group of legs and the correct using of artificial brace of knee joint.Results Range of joint motion could reach 95°after 2 weeks and 125°after 4 weeks postoperation.Score of joint function(Lysholm)could reach(74.8±5.7)after 6 weeks,(80.0±2.3)after 9 weeks,(91.8±3.4)after 12 weeks, and(94.5±2.2)after 1 year.Conclusion Selective perioperative rehabilitation nursing instruction is the important guarantee of function recovery.

Objective To evaluate the effect of neuraxial and general anaesthesia for total joint arthroplasty by meta-analysis.Methods We searched online Pubmed,Web of science,Cochrane li-brary,CNKI,CBM and searched the literature of the Chinese series journals.All randomized controlled trials (RCT)that met their standards of neuraxial and general anaesthesia for total joint ar-throplasty were collected.The quality of trials was strictly assessed.RevMan 5.3 software was used for data analysis.Results Twenty-one RCTs involving 1 874 cases were included.Compared with general anaesthesia,the pooled data showed that the neuraxial anaesthesia significantly reduced blood loss (WMD=-97.52,95% CI = - 1 73.60-- 21.44,P = 0.01 ),associated with lower risk of deep vein thrombosis (RR=0.68,95%CI=0.48-0.95,P =0.02)and pulmonary embolism (RR=0.58, 95%CI=0.35-0.91,P =0.03),decreased the number of postoperative nausea and vomiting (RR=0.74,95%CI=0.60-0.92,P =0.008).Subgroup analysis showed that compared with general anaes-thesia,the neuraxial anaesthesia associated with lower risk of deep vein thrombosis (RR=0.5 1,95%CI=0.38-0.69,P < 0.000 01 )and pulmonary embolism (RR = 0.34,95% CI = 0.18-0.65,P =0.001)in patients who did not receive chemical antithrombotic prophylaxis.Conclusion Neuraxial anaesthesia seems to improve the outcome of patients undergoing total joint arthroplasty and reduce postoperative complications.

Objective By using multi detector row spiral CT (MDCT) to investigate the CT imaging findings of gallbladder abnormalities caused by hepatic parenchymal diseases and those of inflammatory cholecystitis. Methods CT and clinical data of 80 patients with gallbladder abnormalities were retrospectively reviewed. Fifty patients were in hepatic disease group, including 20 chronic hepatitis, 25 liver cirrhosis, and 5 cirrhosis with hepatocellular carcinoma. Thirty patients were in inflammatory group, including 19 chronic cholecystitis, 6 acute cholecystitis, 3 cholecystitis with acute pancreatitis, 1 gangrenous cholecystitis, and 1 xanthogranulomatous cholecystitis. All patients underwent MDCT plain scan and contrast enhanced dual phase scanning of upper abdomen. Results In hepatic disease group, 48 cases had evenly thickened gallbladder wall (96%) with mean thickness of (3.67?0.49) mm; 38 cases had clear gallbladder outlines (76%); 38 cases had gallbladder wall enhancement of various degree (76%); 14 cases had gallbladder bed edema and localized non dependant pericholecystic fluid collection (28%). In inflammatory cholecystitis group, 28 cases had obscuring gallbladder outlines (93%) ; 26 cases had gallbladder wall evenly thickened (87%), 4 cases showed unevenly thicked wall (13%), the mean thickness being (4.54?1.14) mm; 30 cases had inhomogenous enhancement of the gallbladder wall (100%); 9 cases had high attenuation bile (30%); 4 cases had dependant pericholecystic fluid collection (13%); 5 cases had transient enhancement of adjacent hepatic bed in arterial phase (17%); micro abscess and gas in the gallbladder wall was observed in 1 case respectively. Conclusion MDCT can offer imaging findings useful for differentiating abnormal gallbladder changes caused by hepatic parenchymal diseases from those due to inflammatory cholecystitis.

AIM: To investigate the effects of fluvastatin on the airway remodeling in a guinea pig model of asthma. METHODS: Asthmatic guinea pig model was established by intraabdominal injection of ovalbumin and aluminium hydroxide and challenged with ovalbumin once every other day for 60 days. 30 guinea pigs were randomly divided into three groups: control group ( n= 10), asthma group ( n= 10) and fluvastatin plus asthma group ( n= 10) in which fluvastatin was inhaled at concentration of 0.5 g/L 30 min before every challenging. The thickness of airway smooth muscle layers of every three groups were compared after Haematin-Eosin staining by image analysis system. The level of ras mRNA in airway were examined by Dot-blot molecular hybridization. The expression levels of ras p21 were also examined by immunohistochemical technique. RESULTS: The mean thickness of airway smooth muscle in asthma group was (74 27?3 30) micrometer, greater than that of control group [(38 57?3 37) micrometer ( P
