The efficiency of treating citric acid effluent by green algae Chlorella was investigated. With the highest growth rate, Chlorella vulgaris C9-JN2010 that could efficiently remove nutrients in the citric acid effluent was selected for scale-up batch experiments under the optimal conditions, where its maximum biomass was 1.04 g l(-1) and removal efficiencies(More)
BACKGROUND To discuss the advantage of central pancreatectomy in the patients with benign tumors of the neck and body of the pancreas. METHODS Eight patients from January 1990 to December 2007 were retrospectively analyzed in our hospital. The operation is carried out by exposition of the pancreatic neck and body involved by the lesion. Thereafter, the(More)
The aim of this study was to study the effects of carbonic anhydrase IX (CA IX) towards the invasion and metastasis of pancreatic cancer. The expressions of CA IX in 58 cases of pancreatic cancer and paired paracancerous normal tissues, obtained from 2005 to 2012 in the first Affiliated Hospital of China Medical University, were detected, as well as its(More)
Colorectal cancer (CRC) is one of the most common cancer types worldwide. Octamer transcription factor 1 (OCT1) is associated with tumor progression and a poor patient survival rate. However, little is known regarding the effect of OCT1 in CRC. Moreover, because the epithelial-to-mesenchymal transition (EMT) is a key player in metastasis, whether OCT1(More)
Batch, modified semi-continuous and continuous cultivations of Chlorella vulgaris C9-JN 2010 cells in municipal effluent were performed and analyzed. The experiments were carried out in 7.5-L photo-bioreactors, to which 2% of CO2 was supplied. Biomass and specific growth rate of C. vulgaris were 0.528-0.760gl(-1) and 0.200-0.374d(-1), respectively.(More)
Pancreatic cancer is usually diagnosed in the advanced stages and is sensitive to only few therapies. The forkhead box L1 (FOXL1) and protein phosphatase 2A (PP2A) have been recognized to be tumor suppressive in human pancreatic cancers. In the present study, we co-expressed the two tumor suppressive molecules with a '2A peptide' linker, which guaranteed(More)
Our earlier work showed that Musashi (MSI)-2 promoted the development of pancreatic cancer (PC) by down-regulating Numb, which prevented murine double-minute (MDM)-2-mediated p53 ubiquitin degradation. Thus, we investigate the relationship among MSI2, Numb, MDM2, and p53 in PC in vitro and invivo, an association that has not been reported to our knowledge.(More)
A retrospective analysis of prognosis of GIST was used to assess the prognostic effects of hemorrhage of digestive tract induced by mucosal invasion of primary gastrointestinal stromal tumors and related mechanisms. The conclusion is that GISTs with gastrointestinal hemorrhage are more likely to recur, which indicates poor prognosis. Therefore,(More)
Intrahepatic biliary cystadenoma (IHBCA) is a rare type of liver tumor. There are no specific diagnostic methods for IHBCA, so its preoperative diagnostic rate is still fairly low. The aims of this study were to evaluate the clinical manifestations, diagnosis, and treatment of IHBCA. We retrospectively analyzed data from 14 patients treated in our hospital(More)
OBJECTIVES To increase the diagnosis and treatment of ectopic ACTH syndrome. METHODS The data of 12 ectopic ACTH syndrome patients treated from 1985 to 1999 were retrospectively analyzed. RESULTS Twelve patients were diagnosed as having ACTH syndrome by endocrinary test and primary tumors were ascertained by imaging examination. Follow-up from 7 months(More)
