[Spatial and temporal variation in normalized difference vegetation index of vegetation in Liaoning Province from the perspective of ecogeographic zoning].

Normalized difference vegetation index (NDVI) is an important indicator reflecting vegetation cover and growth status. It is of significance for regional ecological conservation and natural resource management to investigate its spatial and temporal variation trends and response to ecological factors. We divided Liaoning Province into three ecological geographical regions, including northwest agro-pastoral zone, central agricultural zone, and eastern agroforestry zone.

FOXO6 promotes gastric cancer cell tumorigenicity via upregulation of C-myc.

The aberrant regulation of many related genes is involved in the development and progression of gastric carcinoma. In the present study, we show that mRNA and protein levels of FOXO6 are upregulated in gastric cancer tissues. Forced overexpression of FOXO6 promotes gastric cancer cell proliferation, while knockdown of FOXO6 expression inhibits proliferation.

Decreased NPC1L1 expression in the liver from Chinese female gallstone patients.

Background: Cholesterol gallstone disease is a very common disease in both industrialized and developing countries. Many studies have found that cholesterol gallstones are more common in women than men. The molecular mechanisms underlying the relationship between female gallstone disease and hepatic sterol transporters are still undergoing definition and have not been evaluated in humans.

[The characteristic of severe acute pancreatitis and the selection of the therapeutic strategy].

Objective: To investigate the relationship between the clinical character and therapeutic strategy and prognosis in severe acute pancreatitis.

Methods: From January 2001 to December 2005, 783 patients with SAP were treated. Therapeutic strategy was selected based on the preliminary scheme for diagnosis and treatment of severe acute pancreatitis by pancreatic surgery society of CMA.

[Comparison of efficacy between ceftriaxone and cefoperazone plus sulbactam in peri-operative treatment of acute suppurative cholangitis].

Objective: To compare the efficacy of ceftriaxone and that of cefoperazone plus sulbactam (sulperazon) in controlling infection, in scavenging bacteria from bile, and in their costs when treating acute suppurative cholangitis with choledochostomy.

Methods: Patients were randomly assigned to two groups: the ceftriaxone group (R-group, n=95) and sulperazon group (S-group, n=95). Before choledochostomy, both groups received one intravenous dose of the corresponding antibiotics: and 2 g ceftriaxnoe for the R-group, 2 g sulperazon, containing 1 g cefoperazone and 1 g sulbactam, for the S-group.

The role of endoscopic retrograde cholangiopancreatography in perioperative period of laparoscopic cholecystectomy.

Objective: To explore the indications and the value of endoscopic retrograde cholangiopancreatography (ERCP) in perioperative phase of laparoscopic cholecystectomy.

Methods: From January 1998 to April 1999, a total of 1500 consecutive laparoscopic cholecystectomies were analyzed. The indications for preoperative group (n=33) included elevated bilirubin level and alkaline phosphatase level, jaundice, pancreatitis, abnormal liver function, dilated bile duct and/or stones on ultrasound or CT.
