Objective:To analyze CT characteristics of pancreatic carcinoma coexisting with chronic pancreatitis versus chronic pancreatitis in order to improve its CT differential diagnostic accuracy.Methods:CT findings in 14 cases of pancreatic carcinoma coexisting with chronic pancreatitis and 15 cases of chronic pancreatitis were retrospectively analyzed.Both plain and enhanced CT scans were performed in all cases.Thin-layer scan was practiced when required.Observation was focused on the size,shape,density of pancreas,its relationship with Peripancreatic tissues,the images of enhancement,and the location,size,density of pancreatic carcinoma.Moreover,observation was focused on the dilation of common bile duct,main pancreatic duct and hepatic bile duct Then,CT characteristics of pancreatic carcinoma coexisting with chronic pancreatitis and chronic pancreatitis were analyzed and compared.Results:In the pancreatic carcinoma coexisting with chronic pancreatitis group,all cases have mass,and noenhancement in the arterial phrase.Peripancreatic blood vessels were invaded or surrounded(5 cases and 4 cases respectively).Peripancreatic adipose were not seen enough(5 cases).Lymph node enlargement(4 cases),Liver metastasis(5 cases).Dilation of common bile duc(t8 cases,9.67 mm?2.64 mm),6 of which showed broke off abruptly.Pancreas atrophy(6 cases),Calcification(4 cases),Dilation of main pancreatic duc(t7 cases),Pseudocys(t2 cases).In chronic pancreatitis group,pancreatic mass(2 cases),one of which showed no enhancement in the arterial phrase;Peripancreatic blood vessels was surrounded by Peripancreatic mass and the boundary between blood vessels and adipose was not clear(1 case);None of the cases was seen Peripancreatic blood vessels invasion;no liver metastasis or Lymph node metastasis.Dilation of common bile duc(t3 cases,7.53 mm?1.45 mm),one of which showed broke off abruptly.Pancreas atrophy(7 cases),Calcification(5 cases),Dilation of main pancreatic duct(7 cases,4.73 mm?3.04 mm),Pseudocyst(4 cases).Conclusion:Style of mass dynamic enhancement of pancreatic carcinoma coexisting with chronic pancreatitis,Peripancreatic blood vessels invasion,liver metastasis,and lymph node metastasis are important basis of CT differentiation of pancreatic carcinoma coexisting with chronic pancreatitis from chronic pancreatitis.

Vav3 oncogene is a member of the Vav family. Vav3 protein contains multiple functional motifs and is involved in cancer development and progression through its role in various cellular signaling processes, including cytoskeleton organization, calcium influx, genetic transcription, cell transformation, proliferation and apoptosis. In addition, Vav3 interacts with estrogen receptor and enhances ERα-mediated signaling axis, therefore plays an important role in breast cancer.

Objective To analyze the clinical behavior and correlative mechanism of the patients with the syndrome of neck injury associate with craniocerebral injury,to investigate its incidence for contributing to the diagnosis and therapy of the patients with the craniocerebral injury and improving the postoperative result. Methods Two hundred and eighty-three patients with craniocerebral injury treated from June 2000 to July 2003 were studied retrospectively. Results In 283 patients, 42( 14.8%) patients presented the syndrome of neck injury clearly in symptom or sign, of whom 39 ( 13.7% ) patients were diagnosed neck injury finally, 3 (1.1%) patients were clinically conclude neck injury. The syndrome mainly presents with noncerebral and nonaural vertigo incorresponding with the recovery of brain injury. Noncerebral, nonaural and nondigestive vomit. Intractable nuchal rigidity incorresponding with the recovery of brain injury. Motion and position limited, stubborn neck malaise, transient spinal cord injury. The symptoms were easy to be improved by neck motion control, neck traction,block therapy, massage and physiotherapy lamp. Conclusion The syndrome of brain-neck injury is a common injury. To learn the syndrome and take the regular therapy can improve the therapeutic efficacy of the craniocerebral injury.

Objective To develop an informatized continuous education system for theater nurse based on PDCA theory.Methods The system was gifted with the functions of learning planning, learning execution, learning checking, data management and system management based on PDCA theory, informatized technology and other learning systems.Results The system behaved well in overall flow and configuration, man-machine interaction and application, which facilitated the nurses to learn with fragmented time.Conclusion The nursing continuous education is enhanced greatly with the system.

Objective To study the effect of different draining way in the surgical treatment of chronic subdural haematoma (CSDH). Methods 126 patients with CSDH diagnosed by CT scanning or MRI were enrolled. The burr-hole was made at the site of the maximal hematoma thickness. A drainage tube was placed towards either the occipital (group A) or frontal ( group B) region as far as possible respectively, and for the latter, a lateral aperture was made about 2 cm far from the burr-hole on the side of the tube. The surgical complication (such as pneumocephalus, brain injury and recurrent hematoma et al.) and therapeutic efficacy of the two treatments were compared and analyzed to evaluate an optimal surgical technique. Results After treatment, complication rate in group A is 30%, the occurrence of complications in group B rate is 2% (P <0.05); operation time and hospitalization time in group B was significantly shorter than that in group A (P <0.05). Conclusion In the surgical treatment of CSDH, improved drainage pathway is safe and effective, which could improve the treatment efficacy and is worthy of clinical promotion.

Lipoprotein lipase (LPL) is the rate-limiting enzyme for the hydrolysis of the triglyceride core of circulating triglyceride-rich lipoproteins.LPL can not only affect the lipoprotein level,but also play an important role in the development of atherosclerosis.LPL gene polymorphisms may affect LPL activity,and therefore have both pro-and anti-atherogenic effects.This article reviews the relationship between LPL gene polymorphism and atherosclerosis.

Healthcare-associated pneumonia(HCAP)is a new concept defined by the 2005 American Thoracic Society/Infectious Diseases Society of America(ATS/IDSA)guidelines for the management of adults with hospital-acquired,ventilator-associated,and healthcare-associated pneumonia.In order to provide helpful advice for clinicians,this review recommends how to choose the site of treatment,general management strategies and initial empirical antibiotic therapy in patients with HCAP,and introduces some new antibiotics may be useful in treatment of HCAP.

Due to the complicated and changeable clinical symptoms,and inexact pathogenesis,leukemia was facing huge challenges in diagnosis and therapy.Aptamer could be selected through CELL-SELEX.The aptamer not only display high affinity and specificity to target cell,but also it could discriminate the specific stage of cell,such as different classification,normal and tumor cells.So CELL-SELEX has great potention in the researches of leukemia.This paper systematically summarized the advantages of CELL-SELEX,the application in specific leukemia diagnosis,targeted therapy and the discovery of cancer biomarkers.(Chin J Lab Med,2013,36:377-379)
