Objective To explore the effects of various dosage and multiple course of Dexamethasone(DEX) on the expressions of WNTs,?-catenin and glycogen synthase kmase-3?(GSK-3?) genes in the lung of premature rats on the 19th day of embryo.Methods Twelve pregnant SD rats were divided into 3 groups randomly:small dose DEX group,large dose DEX group and control group with 4 rats in each group.The rats in control group were injected with saline 9 g/L;rats in small dose DEX group were injected with DEX 0.4 mg/(kg?d),and the rats in large dose DEX group were injected with DEX 0.8 mg/(kg?d) after DEX was diluted to 0.5 mL with saline.On the 19th day of gestation,fetuses were surgically taken out.The reverse transcription polymerase chain reaction PCR method was used to detect expressions of WNT7b,WNT5a,WNT2,GSK-3? and ?-catenin genes mRNA.Results The expressions of WNT7b(0.55?0.19,0.64?0.54)and ?-catenin(2.03?0.58,2.40?0.89)genes mRNA in small dose DEX group and large dose DEX group were significantly higher than those of control group(WNT7b:0.18?0.10,?-catenin:1.77?0.54)(Pa

The occurrence of iliac vein compression syndrome(IVCS) has the anatomic factor.IVCS has no specific symptoms and signs.The diagnosis of IVCS is mainly made by venography, intravascular pressure measurement, intravascular ultrasound, Doppler ultrasound,magnetic resonance venography, and CT.Before the occurrence of acute iliofemoral thrombosis,the treatment of IVCS is conservative therapy.The purpose of surgical intervention is to resolve the obstruction and keep the blood flow. The surgery of occluded iliac veins secondary to IVCS is now to be replaced by endovascular reconstruction. IVCS can be treated correctly before the occurrence of iliofemoral thrombosis and its sequelae can be reduced greatly, if the diagnosis of IVCS can be made as early as possible,and the degree of the stenosis of the iliac vein,the characteristics of its hemorheology and hemodynamics can be understood in time.

Although the relationship between tumor and venous thromboembolism has been demonstrated, the clinical implications of this association still have to be thoroughly elucidated. The aim of this paper is to review the pathogenetic mechanisms accounting for the development of venous thrombosis, the relationship between tumor and venous thromboembolism, the prophylaxis and treatment of venous thrombosis in tumor patients.

Objective To determine the collagen deposition in adventitia of venous wall and the influence of removal venous thrombus by Fogarty balloon catheter on venous wall at different time.Methods The collagen deposition in adventitia of venous wall in inferior vena caval thrombosis in rats, and the injury of venous wall caused by Fogarty balloon catheter removal of thrombus at different time were observed. Results Collagen deposition in adventitia of venous wall increased with time. The peak of collagen deposition was 10 days after thrombus formation, which was significantly different from the control group (P
