1. Methods Human umbilical vein endothelial cells ( HUVECs ) were cultured in vitro.

2. Methods: Umbilical vein, ductus venosus and venous ligament and ligamentum teres hepatis anatomized, observed and measured.

3. Objective To explore the effect of umbilical vein catheterization on premature infants.

4. Methods: This study is based on human umbilical vein endothelial cell line ( ECV 304 ).

5. To study stress response in human umbilical vein endothelial cells ( HUVEC ) infected with Hantavirus ( HTV ).

6. Conclusion: Rescuing the newborn by the umbilical vein for the medicine primarily complex therapy to suffocate palely may enhance the cure rate effectively, and prevent the newborn complication.

7. AIM : To study stress response in human umbilical vein endothelial cells ( HUVEC ) infected with Hantavirus ( HTV ).

8. URPOSE To study whether or not the umbilical vein endothelial cell (HUVEC) can secrete thromboxane and the effect of sera from patients with pregnancy-induced hypertension (PIH) on its secretion.

9. Methods: Umbilical vein, ductus venosus and venous ligament and ligamentum teres hepatis were anatomized, observed and measured.

10. Objective: To know about the psychological state of gravida before undergoing prenatal diagnosis via umbilical vein puncture, so as to provide effective psychological nursing for them.

11. Objective To study the transfection effects of ultrasound microbubbles enhanced TDL compound mediated HGF gene in human umbilical vein endothelial cell(HUVEC).

12. Using flow chamber, we quantitatively studied the effects of pentoxifylline on normal leukocytes adhering to cultured human umbilical vein endothelial cells.

13. Objective: To study the effect of endothelial lipase on the bionomics of human umbilical vein endothelial cell.

14. A sensitive and quantitative in vitro analysis method was established to detect the nascent RNAs stimulated by angiogenin using the nuclei isolated from human umbilical vein endothelial cells (HUVE).

15. To investigate protective effect of total flavonoids of Hedysarum polybotry on human umbilical vein endothelial cells injury treated by high glucose.

16. At present, the diagnosis of DS mainly depends on cytogenetic analysis through amniocentesis,[sentencedict .com] chorionic villus sampling or puncture of umbilical vein to recovery fetal cell.

17. Objective:To Study the influence of Yangyin Recipe to the concentration of Endotheliolyisin(ET)and Nitrogenmonoxide(NO)by cultivating endotheliocyte of human umbilical vein.

18. Material and methods:A micropipette aspiration technique was adopted to investigate the adhesive force of rat PMN on human umbilical vein endothelial cells(HUVECs).
