Comparison analysis in synchronous and metachronous metastatic colorectal cancer based on microarray expression profile.

Background/aims: Colorectal cancer (CRC) is one of the most common malignancies, and liver metastasis is one of the major causes of death of CRC. This study aimed to compare the genetic difference between metachronous lesions (MC) and synchronous lesions (SC) and explore the molecular pathology of CRC metastasis.

Methodology: Microarray expression profile data (GSE10961) including 8 MC and 10 SC was downloaded from Gene Expression Omnibus.

Effects of intensive insulin therapy combined with low molecular weight heparin anticoagulant therapy on severe pancreatitis.

The current study explored the effects of intensive insulin therapy (IIT) combined with low molecular weight heparin (LMWH) anticoagulant therapy on severe acute pancreatitis (SAP). A total of 134 patients with SAP that received treatment between June 2008 and June 2012 were divided randomly into groups A (control; n=33), B (IIT; n=33), C (LMWH; n=34) and D (IIT + LMWH; n=34). Group A were treated routinely.

[Comparison of different methods for the isolation of human umbilical cord mesenchymal stem cells].

Objective: To explore the most appropriate method for the isolation of human umbilical cord mesenchymal stem cells (MSCs) through a comparison of different methods.

Methods: Fifteen umbilical cord specimens from full-term healthy fetus with caesarean birth were completely rinsed with phosphate buffer saline (PBS) and sliced into 1 mm(3) tissue blocks after removal of umbilical vessels and external membrane. These tissue blocks were averagely divided into 4 groups after washing and centrifuge.

Prognostic significance of microRNA-141 expression and its tumor suppressor function in human pancreatic ductal adenocarcinoma.

Increasing evidence shows that dysregulation of microRNAs is correlated with tumor development. This study was performed to determine the expression of miR-141 and investigate its clinical significance in pancreatic ductal adenocarcinoma (PDAC). Taqman quantitative RT-PCR was used to detect miR-141 expressions in 94 PDAC tissues and 16 nontumorous pancreatic tissues.

Basic fibroblast growth factor/vascular endothelial growth factor in the serum from severe burn patients stimulates the proliferation of cultured human umbilical cord mesenchymal stem cells via activation of Notch signaling pathways.

Background: Mesenchymal stem cells (MSCs) are the leading cellular constituents used in regenerative medicine. MSCs repair and reconstruct wounds of acute traumata and radiation-induced burns through proliferation, differentiation, and trophic activity. However, repair effect of MSCs on severe burn wounds remain to be clarified because severe burns are much more complex traumata than radiation-induced burns.

[The clinical study of percutaneous transhepatic radiofrequency ablation combined with tumor edge of percutaneous absolute ethanol injection on liver cancer adjacent to major blood vessels].

Objective: To explore the effects of percutaneous transhepatic radiofrequency ablation (PRFA) combined with tumor edge of percutaneous absolute ethanol injection (PEI) on liver cancer adjacent to major blood vessels.

Methods: Seventy five patients with liver cancer adjacent to major blood vessels were randomly divided into two groups: PRFA+PEI therapy group (38 cases) and PRFA control group (37 cases). Tumor necrosis rate, AFP levels, local recurrence rate, median for survival time and cum survival were used as the evaluation index to evaluate the efficacies of the two methods.

[Effects of intensive insulin therapy on serum immunoglobulin, complement levels and phagocytosis of monocytes in patients with severe trauma].

Objective: To investigate the influence of intensive insulin therapy on serum immunoglobulin (Ig), complement levels and phagocytosis of monocytes in patients with severe trauma.

Methods: Severe injured patients with injury severity score (ISS)>20 in surgical intensive care unit (ICU) were randomly divided into two groups, intensive insulin therapy and conventional therapy. Blood glucose levels in intensive insulin therapy and conventional therapy groups were maintained at 4-6 mmol/L and <11.

[Effects of anticoagulation therapy with low molecular weight heparin in acute pancreatitis].

Objective: To evaluate the effects of anticoagulation therapy with low molecular weight heparin in acute pancreatitis.

Methods: Low molecular weight heparin, in a dose of 40 mg or 0.01 ml/kg, by subcutaneous injection, every 12 hours, was administered to 17 acute pancreatitis patients combined with conventional therapy.
