Objective:To analyze the appearances of multiple MRI sequences and the accuracy of the assessment of resectability in caput pancreatic carcinoma.Methods:MRI appearances were analyzed retrospectively in nineteen patients with histopathology or clinical examination proved carcinoma in the head of pancreas,and the assessment of resectability was compared with the findings of surgical and histopathology.Plain MRI sequences included:coronal scanning with T2-weighted 2D true-fast imaging with steady-state free precession,axial scanning using T1-weighted fast low angle single shot with fat suppression,T2-weighted half-Fourier single shot turbo spin-echo with fat suppression,and MRI cholangiopancreatography.The contrast-enhanced scanning procedures were axial scanning using T1-weighted 3D volume interpolated breathhold examination with fat suppression,the imaging were obtained during arterial phase,portal vein and delayed phase scanning.Results:Of 19 lesions in these patients,17 lesions showed hypo-intensity on T1WI of plain sequences,and normal pancreats showed hyper-intensity.15 lesions showed hyper-intensity or immingled-intensity on T2WI,one appended with cyst.During pancreatic arterial phase,18 lesions did not show enhancement,contrasting with the normal pancreas showing evidently enhancement,so the borderline of carcinoma was clear.During portal vein and delayed phase,17 lesions showed inhomogeneous slight enhancement,peripheral vas of pancreas in 17 cases were contacted or involved by tumor.3 transfer lesions in hepar showed slight enhancement.13 cases showed dilatation at both common bile duct and pancreatic duct as a typical double duct sign on MRCP.According to the assessment of MRI,7 cases could be resected,and 12 cases could not be resected.The assessment of 14 cases agreed with the surgical and histopathological findings.Conclusion:Carcinoma of pancreatic head is shown with many features on multiple MRI sequences.MRI examination has a high accuracy for the diagnosis and the assessment of resectability in carcinoma of pancreatic head,which is helpful in choosing project of therapy.

Sphingolipids are essential components of cellular membrane , regulating important physiologic function of cells .Al-terations of sphingolipid metabolism are closely related to the pathogenesis of several chronic diseases .Ceramide biogenesis , the center of sphingolipid metabolism , includes de novo ceramide synthesis , ceramide formation via breakdown of complicated sphingolipids and so on . Recent studies found that aberrant sphingolipid metabolism is strongly linked to insulin resistance associated with obesity .The review fo-cuses on recent advances about aberrant sphingolipid metabolism in the pathogenesis of insulin resistance associated with obesity .

Ostial lesions present many challenges for percutaneous coronary intervention (PCI). Coronary anomaly will further increase difficulties in performing PCI for the patient. We present such a case as ostial occlusion of an right coronary artery with high takeoff. A 77-year-old male was referred to our institution with a diagnosis of non-ST elevated acute myocardial infarction. Selective coronary angiography and nonselective ascending aortography could not identify the origin of the right coronary artery. Multi-slices computed tomography showed RCA ostial totally occluded. A successful PCI was performed and a perfect final result was achieved utilized with many tips and tricks, including buddy wire technique and focused-force angioplasty.

Eukaryotic cells maintain cellular homeostasis by regulating the process of protein degradation and organelle turnover.Autophagy is a ubiquitin-like degradation process,and plays an essential role in cellular development,differentiation,and elimination of damaged organelles and protein.Previous studies mostly focused autophagy on tumor and neurodegenerative diseases,whereas studies about autophagy and energy remain not clear.Since 2009,an increasing number of studies have showed light on the importance of autophagy in regulating lipid metabolism.The review focuses on the relationship between autophagy and differentiation of adipocytes,lipogenesis,and lipolysis.

Post-resuscitation multiple organ dysfunction syndrome(PR-MODS) is a major cause of low survival rate in patients with cardiac arrest.To fully understand the concept of PR-MODS is beneficial for estimating the state of illness,adjusting the therapy and eventually increasing the survival rate.This article reviews the development of PR-MODS concept and compares it with MODS of other causes,including their pathogeny,pathology,mechanism,diagnosis and therapy.

Object To study the effects of GANPISHU INSTANT GRANULE * on experimental hyperlipemia model of rats Methods: Hyperlipemia models were prepared by special feeding method and their biochemical parameters determined Results GANPISHU INSTANT GRANULE can obviously lower serum total cholesterol (TC), triglyceride (TG), LDL C and apolipoprotein B while increase the high density lipoprotein total cholesterol ration Conclusion GANPISHU INSTANT GRANULE showed significant blood lipid regulation effects on hyperlipedemicrats These results provided an important basis for exploiting and utilizing GANPISHU INSTANT GRANULE

According to the needs of maintenances a detection kit for ECG cable is developed to detect the onoff condition of the wire, which can form a loop, and to indicate the result on a LED. The kit proves to be simple and practical and thus can significantly increase the maintenance efficiency of ECG cable.

Objective To compare the changes in the management of severe preeclampsia during a ten-year period, and the maternal and perinatal outcome. Methods Totally, 305 cases of severe preeclampsia were collected in our hospital from January 1999 to December 2003. The management, mode of delivery, frequency of complications and maternal and fetal outcomes were compared with the 349 cases from January 1994 to December 1998. Results The incidence of severe preeclampsia, that being diagnosed at 0. 05], but the perinatal mortality rate of those cases
