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.

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.

Objectives To evaluate the effects of“the Seven Acupoints of the Cranial Base”(SACB) in improving quality of life(QOL)of patients with PD. Methods The study Subjects were seventy(70)patients with a diagnosis of Parkinson's disease. The Subjects were divided into two groups, i.e. acupuncture group and drug group.The former was treated by SACB every two days,while the latter took Levodopa and Benserazide Tablet250mg tid. The subjects all received treatment for 6 months. PDQ-39,UPDRSⅡand PDSS were adopted to measure quality of life at 4 time points. Results The total effective rate of the treatment group was 85.71%, the control group was 71.43%. And there was a statistical difference of level distribution between the two groups(P<0.01). The total score of PDQ-39, UPDRSⅡ and PDSS of patients in the treatment group [(20.41± 11.64), (9.09±5.02), (126.31±8.37)]were significantly improved compared with the control group[(27.48± 8.69), (10.29±4.93), (109.94±8.11), P<0.01]. The 5 dimension score of PDQ-39, and the 4 single item score of UPDRSⅡ in the treatment group[(8.60±5.07), (3.20±2.08), (2.34±1.73), (1.20±1.68), (1.63±1.96),(1.31±0.68), (0.77±0.94), (0.91±0.74), (0.77±0.65)]were significantly improved compared with the control group[(11.69±4.11), (5.09±3.72), (5.37±1.99), (2.86±2.33), (2.74±2.08), (1.74±0.98), (1.31±0.93), (1.43±0.78), (1.20±0.68), P<0.01 or 0.05]. Conclusion SACB can markedly and multi-dimensionally improve the QOL of patients with PD and has a higher efficacy than Levodopa and Benserazide Tablet.

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.

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.
