Objective To improve the recognition of intrahepatic biliary cystadenoma.Methods The clinical manifestations,radiologic features,diagnosis and surgical treatment of 18 patients with intrahepatic biliary cystadenomaadmitted in our hospital during the recent 8 years were retrospectively analyzed.Results Four cases were discovered by general medical examination,while the other 14 patients had varying symptoms that included right upper abdominal discomfort or pain in 11 cases,abdominal mass in 3 cases,and jaundice accompaniedby fever in 2 cases.B ultrasound and CT scan showed intrahepatic cystic occupying lesions consistingof multilocular or single cyst,and usually with papillary structures in the cyst wall.All of 18 cases received surgical resection.The patholgic dingnosis was intrahepatic biliary cystadenoma in all the 18 cases,and 6 of them showed malignant change.The average survival time of maligmant patients was 35(27-58)months.Conclusions Preoperative diagnosis of intrahepatic biliary cystadenoma is difficult.Intrahepatic biliarycystadenoma is easy to develop into cystadenocarcinoma.Early surgical resection is necessary,and can effectively prevent recurrence or malignant transformation.

A new target in cancer treatment involves tumor-associated macrophages (TAMs) which are infiltrated in microenvi-ronment. By secreting a wide range of cancer-promoting cytokines, such as vascular endothelial growth factor, interleukins, and matrix metalloproteinase, TAMs can promote the proliferation, invasion, and metastasis of cancer cells. Cyclooxygenase-2 (COX-2), an inflam-matory factor that is significant for angiogenesis and immunoregulation within the local microenvironment, may also contribute to can-cer progression and act as a novel target for breast cancer therapy. Several COX-2 inhibitors, such as celecoxib, have shown potential as suppressors of TAMs and the microenvironment. Hence, the current study discusses the crosstalk between TAMs-delivered important cytokines and COX-2 in the breast cancer microenvironment, and then analyzes the value of homologous antagonists alone or in combi-nation with COX-2 inhibitors. This paper aims to provide the theoretical principle of multi-target selection in TAMs blockage, and offer a new direction for biological targeted therapy in breast cancer treatment.

Tumor markers can reflect tumor existence,and open an entrance to diagnose tumor at early stage.Recent researches reveal that gastric cancer related tumor markers such as microRNAs,enzymes,cytokines and antibodies-antigens are significant for the diagnosis,treatment,relapse surveillance,prognosis evaluation of gastric cancer.

Objective To investigate the effect of acute physiology and chronic health evaluationⅡ ( APACHEⅡ) scoring system on evaluating the severity and prognosis in severe acute pancreatitis(SAP). Methods The APACHEⅡ scores were analyzed in 52 patients with SAP. Results The mean APACHEⅡ score of SAP was 16.60?9.07(8～40), and there were significant differences between the scores not only in Grade SAPⅠand Grade SAPⅡ(?

OBJECTIVETo analyze the risk factors of liver metastasis in patients after radical resection of pancreatic cancer.

METHODSOne hundred and twenty-four patients with non-metastatic, resectable pancreatic cancer treated in our department between 2006 and 2012 were included in this study. All of these patients underwent resection of the primary tumor combined with extensive lymph node dissection. The development of postoperative liver metastases was carefully followed up, and the clinicopathological factors and molecular characteristics were evaluated by univariate analysis and multivariate logistic regression using SPSS 16.0 software.

RESULTSForty-eight cases of liver metastases were found among the 124 cases of pancreatic cancer after radical surgery (38.7%). The rate of liver metastasis of pancreatic cancer after radical surgery in the age groups < 40, 40-60, and > 60 were 68.8%, 33.3% and 35.1%, respectively. The rate of liver metastasis in the body mass index (BMI) group < 20 kg/m2, 20-25 kg/m2, and > 25 kg/m2 were 21.6%, 44.1% and 52.6%, and the rate of liver metastasis in the time between the onset and diagnosis groups ≥ 3 months and < 3 months were 59.4% and 31.5%, respectively. The rate of liver metastasis in patients with preoperative fatty liver was 14.3% and it was 43.7% in patients without preoperative fatty liver. The rate of liver metastasis in patients of histological high, medium and low grade was 10.0%, 35.4% and 49.0%, respectively. The rate of liver metastasis in patients with venous tumor thrombus was 68.8% and it was 34.3% in patients without venous tumor embolus. The rate of liver metastasis in patients with postoperative chemotherapy was 31.2% and it was 51.1% in patients without postoperative chemotherapy. All those differences had statistical significance (P < 0.05). Univariate analysis revealed that age, body mass index (BMI), time between the onset and diagnosis, preoperative fatty liver, histological grading, tumor invasion depth, venous tumor embolus, and postoperative chemotherapy were significantly related to postoperative liver metastasis. Multivariate analysis revealed five statistically independent risk factors for postoperative liver metastasis: BMI, time between onset and diagnosis, preoperative fatty liver, histological grading, and venous tumor embolus.

CONCLUSIONSOur data suggest that patient's BMI, time between onset and diagnosis, histological grade, and venous tumor embolus are significantly correlated with postoperative liver metastases in patients with pancreatic cancer. Pancreatic cancer patients with preoperative fatty liver have less postoperative liver metastasis.

Endothelial progenitor cells play a significant role in neovascularization of ischemic tissues and in reendothelialization of damaged blood vessels. Cytokines, an important components of micro-environment of angiogenesis,play an important role in regulation of endothelial progenitor cells. The effective application of cytokines can significantly argument the number, enhance the biological function and improve the therapeutic effect of endothelial progenitor cells, which play a positive role in regulation of endothelial progenitor cells.This article briefly reviewed the regulating mechanisms of the vascular endothelial growth factor and other cytokines in a total of 7 endothelial progenitor cells.
