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 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.

To ensure the meridian can be measured and displayed correctly on the human body surface, a visualization method based on impedance and binocular vision is proposed. First of all, using alternating constant current source to inject current signal into the human skin surface, then according to the low impedance characteristics of meridian, the multi-channel detecting instrument detects voltage of each pair of electrodes, thereby obtaining the channel of the meridian location, through the serial port communication, data is transmitted to the host computer. Secondly, intrinsic and extrinsic parameters of cameras are obtained by Zhang's camera calibration method, and 3D information of meridian location is got by corner selection and matching of the optical target, and then transform coordinate of 3D information according to the binocular vision principle. Finally, using curve fitting and image fusion technology realizes the meridian visualization. The test results show that the system can realize real-time detection and accurate display of meridian.

A multi-channel meridian impedance detector used to the 3D meridian visualization positioning is presented. The detector is designed with the four-electrode method based on current driving according to low impedance of the meridian. The detector consists of power-supply module, sinusoidal signal generator, voltage-controlled current source, isolation amplifiers, filter circuit, amplitude detectors and so on.

Objective To investigate the clinical effect of vitapex paste in the treatment of deciduous teeth with periapical inflammation.Methods 112 children with chronic apicitis of deciduous teeth were divided into two groups randomly and averagely.The research group used vitapex paste,while the control group used zinc oxide eugenol paste.The clinical effects of the 2 groups were compared.Results Compared to the control group,the response to root canal filling of the research group was much weaker ( 10.7％ to 25.0％ ),which had statistical difference ( x2 =3.02,P =0.0 1 1 ).There wasalso significant difference betweenthe success rateofthetwogroups after 1 year followed up( x2 =5.16,P =0.004).Conclusion sing vitapex paste for root canal filling had a higher success rate and a weaker respose to root canal filling.
