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.

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.

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 observe the effects of epileptiform discharge and its influence on humpwave sleep spindles after sleep deprivation(SD)in children with epilepsy.Methods Monitoring the wakefulness and sleep EEG of samples of 160 children who were diagnosed epilepsy after SD.Results The detection rate of epileptiform discharge(59.3%)in sleep EEG was higher than that in wakefulness EEG after SD(16.3%)(P

Objective To study the expression site and the role of low-affinity nerve growth factor receptor(P75) in hepatic stellate cells(HSCs) of fibrotic human and rat liver.Methods Left lobe of liver was removed from CCl-4-induced rats fibrosis model and human fibrotic tissue sample was taken from liver puncture.The tissue specimen was routinely paraffin embedded and expression of P75 was detected by histochemical staining using polyclonal antibody against P75.Additionally,HSCs was cultivated and P75 was immunochemically assayed for P75 binding activity. Results P75 was seen abundantly on cell membrane of the cultured HSCs.In the fibrotic tissue of rat liver as well as human fibrotic liver P75 was also positively expressed.Similarly,P75 was found mainly a hepatocye surface in histochemical staining.P75 was not seen by histochemical staining in the normal tissue of human and rat liver.Conclusion P75 used as a new target for the treatment of hepatic fibrosis.

Antiplatelet therapy is a major strategy with a growing body of evidence in management of ischemic cerebrovascular diseases.This article introduces the mechanism of currently available antiplatelet drugs as well as their practice guidelines and evidence from clinical trials.There is currently no robust evidence to support the use of venous antiplatelet agents.Aspirin is the sole evidence-based antiplatelet drug for treatment of acute ischemic stroke.Aspirin,dipyridamole and clopidogrel are effective in secondary stroke prevention.Combination therapy using aspirin plus extended-release dipyridamole is the only combination approach to demonstrate additive benefit.

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.

OBJECTIVE: To investigate the growth inhibition and apoptosis of BGC-823 gastric cancer cells induced by Oridonin and its mechanism. METHODS: The Oridonin-treated BGC-823 cells were detected using MTT, transmission electron microscopy (TEM), TUNEL and flow cytometry (FCM) etc. RESULTS: Oridonin(16, 32, and 64 ?g?mL-1) significantly inhibited the proliferation of BGC-823 cells in dose and time dependent manner, with the inhibition rates at 68.5%, 90.8%, and 94.7%, respectively within 24, 48, and 72 h after treatment with 64 ?g?mL-1 Oridnin. When treated with 32 ?g?mL-1 Oridonin for 2 h,mitochondria and endoplasmic reticulum were proliferated and swelled under TEM; At 8 h,vacuolization of mitochondria and endoplasmic reticulum were noted, the internal structure disappeared, and the nuclear chromatin margination vacuolization were in typical apoptosis change; At 24 h, BGC-823 cells were arrested at G2/M phase, and the apoptosis rate was 37.8% under FCM. CONCLUSION: Oridonin inhibiting proliferation and apoptosis of BGC-823 cells maybe related to G2/M phase arresting, and Oridonin induce apoptosis of BGC-823 cells may through mitochondria or endoplasmic reticulum apoptosis pathway.
