3.Progress in Vav3 and breast cancer research
Journal of International Oncology 2010;37(9):686-688
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.

Journal of Chongqing Medical University 2007;0(10):-
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.
5.Diagnosis and managements in neck injury syndrome associate with craniocerebral injury
Chinese Journal of Postgraduates of Medicine 2006;0(05):-
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.

8.Clinical significance of changes in peripheral lymphocyte count after surgery in early cervical cancer
Chinese Journal of Obstetrics and Gynecology 2014;49(3):208-212
Objective To evaluate the clinical significance of changes in peripheral lymphocyte count after surgery in early cervical cancer.Methods The 123 patients with stage Ⅰ bl and Ⅱ al treated by abdominal type Ⅲ radical hysterectomy from May 2008 to December 2012 were reviewed.The median age of patients was 43 years old (range:30 to 66 years).The median follow-up was 25 months with a range of 5-61 months.Peripheral blood samples were obtained on pre-operative,post-operation day 3 and 7.The log-rank test was used to compare the homogeneity of progression-free survival functions across strata defined by categories of prognostic variables.The Cox proportional hazard model was used to assess the significance of potential prognostic factors for progression-free survival.Results Univariate analyses preoperative lymphocyte count (P =0.012) and lymph nodes metastases status (P =0.001) and parametrial invasion (P =0.013) were significant risk factors for progression-free survival rate.On multivariate analyses,preoperative lymphocyte count [hazard ratio (HR) =6.087,95% CI:1.743-21.251,P =0.005] and lymph nodes metastases status (HR =5.984,95% CI:1.803-19.802,P =0.003) were independent risk factor of progression-free survival rate.Conclusion Peripheral lymphocyte counts after cervical cancer surgery may be a important prognostic factor.
9.CELL-SELEX and its applications in leukemia
Chinese Journal of Laboratory Medicine 2013;(4):377-379
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)
10.Modified posteromedial and posterolateral approaches for the treatment of posterior tibial plateau fractures
Chinese Journal of Orthopaedic Trauma 2012;14(11):945-949
Objective To observe the clinical outcomes of modified posteromedial and posterolateral approaches for the treatment of posterior tibial plateau fractures.Methods Between January 2006 and October 2011,25 patients with posterior tibial plateau fracture were identified.They were 17 men and 8 women,aged from 22 to 76 years (average,46.4 years).According to the AO/OTA classification,there were 4 cases of type 41-B1,6 cases of type 41-B2 and 15 cases of type 41-B3.According to Luo's three-column classification,they were all posterior column fractures.Ten patients with posterolateral tibial plateau fracture were treated by the modified posterolateral approach and the other 15 patients with posteromedial tibial plateau fracture by the modified posteromedial approach.The posterior fractures were fixated with a buttress plate.The knee function was evaluated at the last follow-up by the The Hospital for Special Surgery (HSS) Score.Results All the 25 cases were followed up for a mean time of 13.2 months (from 10 to 24 months).By the radiological Rasmussen criteria for fracture reduction,the mean score immediately after surgery was 16.5 points (from 13 to 18 points),with 20 excellent cases,4 good cases and one fair case.All patients were pain-free with full range of motion.Radiologically,bone union was achieved in all cases after a mean time of 13.9 weeks (from 12 to 18 weeks).No surgery-related complications were found.The mean HSS score was 91 points(range,74 to 97 points) and the good to excellent rate was 100% (17 excellent and 8 good cases) at the last follow-up.The average range of knee motion ranged from 0° to 125°.Conclusion In the treatment of posterior tibial plateau fractures,because the modified posteromedial and posterolateral approaches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating,soft tissues can be well preserved and good functional results can be expected.
