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 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 investigate the prognosis and survival situation of the patients with high risk refractory lymphoma treated by autologous hematopoietic stem cell transplantation .Methods The follow up data in 110 patients with high risk refractory lymphoma treated by autologous hematopoietic stem cell transplantation in our hospital were retrospectively analyzed .The survival and prognosis factors of the patients after autologous hematopoietic stem cell transplantation were analyzed by using the Kaplan-Meier survival analysis and Cox proportional hazard regression analysis .Results The median survival time was 39 .4 months in 110 cases ,the 3‐year overall survival rate (OS) and progression free survival rate (PFS) were 80 .9% and 76 .4% respectively .The pa‐tients achieved CR status before transplantation(P=0 .016) and consolidation therapy after transplantation (P=0 .006) were the favorable prognostic factors of the patients undergoing transplantation .The prognosis in the patients with high LDH values ,IPI score>2 and bone marrow infiltration and HBV infection were poor(P<0 .05) .Conclusion Autologous hematopoietic stem cell transplantation can improve the long‐term survival rate in the patients with high risk refractory lymphoma .

Serum tumor biomarkers are significant for the early diagnosis and treatment,preoperative evaluation,prognosis prediction and relapse surveillance of endometrial carcinoma.Recently,serum CA125 and human epididymal secretory protein 4 are widely recognized as closely related with staging,metastasis and prognosis of endometrial cancer.In addition,the serum miRNAs are characterized by their features of high stability and specificity.Omics studies will be helpful for the general assessment of the initiation and progression of endometrial cancer.Insights into these two aspects will facilitate the identifications of new biomarkers with higher sensitivity and specificity for endometrial carcinoma.

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.

5-Fluorouracil(5-FU)has been widely used to treat gastrointestinal,head,neck,chest and ovarian malignant tu-mors since 1957. As an analogue of pyrimidine,5-FU plays anti-cancer roles by inhibiting thymioylate synthase and integrating its me-tabolites into DNA and RNA. Although 5-FU is one of the first-line therapeutic compounds for gastrointestinal malignant tumor as a sin-gle drug or in combination with other drugs,its effectiveness is hindered by its low efficiency,which may be due to chemotherapy re-sistance. 5-FU chemotherapy resistance may stem from enzyme abnormality,genetic abnormality and tumor microenvironment. In this paper,we make a review about 5-FU actions and the mechanisms underlying chemotherapy resistance.

Objective To explore the expression of caudal type homeobox transcription factor 2 (Cdx2) and liver intestinal cadherin (LI-CD) in intestinal metaplasia ( IM ) of gastric mucosa and gastric adenocarcinoma of the intestinal type (GAIT). Methods By using immunohistochemical method, the ex-pressions of Cdx2 and LI-CD were detected in biopsy sample including 30 cases of GAIT, 30 IM and 30 nor-mal controls. Results The positive rate of Cdx2 expression was 0, 93.3% and 46.7% in normal stomach mucosa, IM and GAIT, respectively. The positive rates of Cdx2 expression in IM and GAIT were significant-ly higher than that in normal stomach mucosa ( P < 0. 005 ), and the expression of Cdx2 in IM was signifi-cantly higher than that in GAIT (P<0. 005). Similarly, LI-CD was also negative in normal stomach muco-sa, and positive rates were 96. 7% and 73. 3% in IM and GAIT group, which were significantly higher than that in normal stomach mucasa (P < 0. 005 ), and LI-CD expression was also significantly higher in IM than in GAIT (P < 0. 05 ). In addition, the staining intensity of Cdx2 and LI-CD expressions in IM exhibited sig-nificant correlation (r=0. 827, P<0.01), but those in GAIT did not (r =0.438, P=0. 117). Conclu-sion Ectopic expression of Cdx2 and LI-CD can be found in IM and GAIT tissues, which could be an early marker in the disease progression. There is correlation between Cdx2 and LI-CD expression in IM tissue of human, and presumably, Cdx2 regulates LI-CD in IM development.
