Background Portacaval shunt （PCS） prevent hepatotrophic factors from flowing into the liver, but they enter directly the systemic circulation and worsen liver injury. This study was designed to investigate the effects of hepatotrophic factors through the portal vein on the liver in rats with portal hypertension after portacaval shunt. Methods Intrahepatic portal hypertension （IHPH） was induced by intragastric administration of carbon tetrachloride, and end-to-side PCS was performed. Eight normal rats served as controls, and eight rats with IHPH served as IHPH model （IHPH group）. Another 32 rats with IHPH-PCS were randomly subdivided into 4 groups： normal saline （NS） given to 8 rats, hepatocyte growth factor （HGF） 8, insulin （INS） 8, hepatocyte growth factor and insulin （HGF＋INS） 8. Hepatotrophic factors were infused into the portal vein through an intravenous catheter. Portal venous pressure （PVP） was measured. The levels of serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were tested biochemically and those of hyaluronic acid （HA） and laminin （LN） were measured by radioimmunoassay. Hepatic fibrosis was assessed histologically and the expression of collagens type I and In were detected immunohistochemically. Ultrastructural change of hepatocytes and the number of mitochondria were observed under an electron microscope. The data were compared between groups and subgroups by Student-Newman-Keuls procedure with SPSS 10.0.Results PVP was significantly higher in the IHPH rats than in the control rats （P〈0.05）. The levels of serum ALT, AST, HA, and LN, hepatic fibrosis score, the amount of collagen deposition, collagens type I and III increased more significantly in the IHPH group than in the control rats （P〈0.05）. The number of mitochondria decreased more significantly in the IHPH rats than in the control rats （P〈0.05）. The levels of serum ALT, AST, HA and LN as well as hepatic fibrosis score, the amount of collagen deposition, and the amount

Background Diabetic lower limb ischemia is a serious complication of diabetes mellitus. This study was conducted to investigate the effectiveness of distal arterial bypass treatment in diabetic patients with lower limb ischemia. Methods From July 2000 to July 2004, 96 lower limbs of 82 diabetic patients （type 2） with severe lower limb ischemia were treated in Xuan Wu Hospital. Arterial bypass with femoro-popliteal polytetrafluoroethylene （PTFE） and graft-tibial autologous grafts was performed on 31 limbs （32.3%）. Popliteal-tibial artery bypass alone was performed on 22 limbs （22.9%）. Combined lilac artery stenting, femoro-popliteal artery PTFE graft bypass, and graft-tibial artery autologous graft bypass was performed on 12 limbs （12.5%）, and femoro-tibial artery graft bypass was performed on 10 limbs （10.4%）. Popliteal-tibial-pedal artery graft bypass was performed on 7 limbs （7.3%）. Results Arterial grafts in 92 limbs of 79 patients were patent on discharge. Three patients with 4 ischemic limbs （3.7%） died of respiratory failure 12 hours, 3 days and 7 days after operation respectively. Early operation success rate was 96.3% （79/82）. Graft patency rate of patients on discharge was 95.8% （92/96）. The short-term total effectiveness rate was 83.3% （80/96）. Foot ulcer healing rate was 35.7% （10/28）. 97.4% （75/77） patients were followed up for a mean of 13.5 months. The long-term total effective rate was 80.7% （71/88）. The total amputation rate was 4.5% （4/88）. Mortality was 4.5%. The total graft patency rate was 90.9% （80/88）.Conclusion In the treatment of diabetic foot, distal lower limb arterial bypass can help to avoid amputation or lower the amputation level, and may promote foot ulcer healing and improve patient＇s quality of life.
