ObjectiveTo summarize the research progress of early allograft dysfunction (EAD) predictors after liver transplantation. MethodThe literatures about the studies of predictive predictors of EAD after liver transplantation in recent years were reviewed. ResultsThe EAD was closely related to the prognosis and long-term survival of patients. In recent years, there were some reports of serum uric acid, neutrophil and lymphocyte ratio, von Willebrand factor to protein C ratio, serum brain natriuretic peptide, cytokine, hyaluronic acid, soluble CD163, serum lipid, lactic acid, coagulation factor Ⅴ, serum phosphorus etc. new serum biomarkers for early detection and recognition the occurrence and development of the EAD after liver transplantation. It was possible to intervene EAD early and effectively after liver transplantation. Conclusions Early recognition and prevention of EAD after liver transplantation is particularly important. Although some new predictive indicators have been proposed to predict occurrence of EAD after liver transplantation, relevant studies are lesser and there are still many problems to be solved. Further studies will be conducted to verify clinical application value of these new indicators.
Objective To investigate the effects of cimetidine on the red cell immune function and interleukin-2(IL-2) in rats with obstructive jaundice. Methods Sixty SD rats were divided into bile duct ligation(BDL) group, cimetidine therapy (BDLC) group and sham operation(SO) group respectively. The red cell immue function and serum IL-2 level were determined with the red cell yeast-rosttes test and radioimmunoassay respectively. Results The red blood cell C3b receptor rosette rate(RBC-C3bRR), the red blood cell immune complex rosette rate(RICR), the red blood cell C3b receptor rosette-forming excited rate(RFER) and serum IL-2 level were significantly lower in BDL group as compared with SO group, the red blood cell C3b receptor rosette-forming inhibitory rate(RFIR) in BDL group was higher than that of SO group. After 7 days’ cimetidine therapy RBCC3bRR, RICR, RFER and IL-2 became higher than those of BDL group, but RFIR was lower than that of BDL group. Conclusion Supplemental cimetidine can significantly enhance the impaired red cell immune function and IL-2 production in rats with obstructive jaundice.
Objective To review the mechanisms of cholesterol gallstones caused by female hormone so as to explore new treatments to prevent gallstones associated with estrogen and progesterone. Methods The literatures on gallstones related with female hormone were reviewed and the mechanisms of cholesterol gallstones were summarized. Results The cholesterol gallstones mechanisms was affected by estrogen through genomic effects，and the nucleation of cholesterol was promoted by estrogen through nongenomic，which resulted in the formation of cholesterol gallstones. And the bile empty dysfunction associated with estrogen through nongenomic effects was also the reason of cholesterol gallstone formation. The G proteins α subunit responsible for the motility of gallbladder were disrupted by progesterone through genomic effects，and the ionic channels and signal transduction were also interfered through nongenomic pathway，which impaired the contraction of gallbladder. However，the nongenomic effects might not play an important role in the gallstones formation caused by progesterone. Conclusions The mechanisms of cholesterol gallstones formation associated with female hormone are complicated，the understanding of chelesterol gallstones formation mechanisms might be helpful to prevent gallstones associated with estrogen and progesterone.
