Objective To explore the relationship between the structure and function of galectin-3， lipid metabolism disorders， and investigate the expression of galectin-3 in the occurrence and progress of lower limb arteriosclerosis block disease. Methods Related articles were reviewed. Results Galectin-3 participates in inflammatory reaction and lipid metabolism disorders， regulates the cell growth， differentiation， adhesion， apoptosis， and angiogenesis， and palys a role in the occurrence and progress of arteriosclerosis obliterans. Conclusion Galectin-3 is correlation with the occurrence， progress， and the prognosis of arteriosclerosis obliterans.
【Abstract】ObjectiveTo detect the levels of homocysteine (Hcy) and anti-phospholipid antibodies (APLA) in the hematoplasma of the patients with deep venous thrombosis (DVT), discuss the reason of DVT recurrence and search for the predictors of it. MethodsSixty cases with DVT in our department from January 2001 to April 2003 were collected, which were divided equally into two groups as primary and recurrent, and first degree relative of the 30 DVT recurrent patients were also collected. The author established a control group using 30 cases of outpatient clinic without varicose veins of lower extremity or insufficient venae profundae. Hcy was detected with fluorescence polarization immunoassay (FPIA) and APLA 〔anticardiolipin antibody, ACLA (IgG, IgM); lupus antibody (LA)〕were detected with enzyme linked immunosorbent assay (ELISA). Odds ratios (OR) were also calculated to assess the relative risk of each study group. ResultsThe values of Hcy and ACLA （IgG， IgM） in the primary group and recurrent group were both significantly higher than those of control group and first degree relative group of DVT recurrent patients (Plt;0.01). The values of Hcy in first degree relative group of DVT recurrent patients was were also much higher than that of control group (Plt;0.05). The 90% quantity of Hcy in control group was 13.1 μmol/L and if taking it as the normal value, the number of cases exceeded this value in primary group, recurrent group and first degree relative group of DVT recurrent patients were 14, 21 and 13 and the OR of them were 2.31, 2.20 and 1.90, respectively. The positive rates of LA were not statistically significant in each group. Conclusion The values of Hcy and APLA both rise in the hematoplasma of DVT patients. There are close relationship between the levels of Hcy and APLA and DVT. The recurrence of DVT is related to high level of Hcy and Hcy is possibly a predictor of DVT.
【Abstract】ObjectiveTo investigate the causes of death in recipient rats after modified orthotopic liver transplantations and the countermeasure.MethodsTwo hundred and ten orthotopic liver transplantations were performed in Wistar and SD rats weighing 250～300 g through modified Kamada’s cuff technique, and to investigate the causes of death and preventive measures. ResultsIt took about (41±5) min, (13±2) min and (45±5) min for donor operation，donated liver trimming and recipient operation respectively. The anhepatic phase was (20±5) min. The 4week survival after transplantation was 90.5%. Nineteen rats died during and after transplantation. The causes of death included: bleeding of suprahepatic inferior vena cava (n=5 ), infrahepatic vena cava thrombosis (n=2), biliary obstruction (n=3 ), portal vein constriction and thrombosis (n=2 ), liver injury(n=1), bleeding of left subphrenic vein (n=2 ), infection (n=2 ), excessively deep anesthesia (n=1), and respiratory failure (n=1). ConclusionThe sophisticated microsurgical technique and the delicate surgical manipulation are very important in preventing operative complications, and the short anhepatic phase of recipient is the key to animal survival, and proper anesthesia is also important to the success of operations. Improving the condition of operation and reasonable use of antibiotics are necessary in preventing infections.
