Chinese Journal of Perinatal Medicine 1998;0(03):-
Objective To evaluate the association of fetal total bile acid (TBA) concentration with fetal adrenocortical dysfunction in intrahepatic cholestasis of pregnancy(ICP). Methods The concentration of TBA, cortisol and DHEA-S in the cord blood were measured in 20 fetuses with maternal ICP (ICP group) and 22 fetuses of normogravidas (control group) after elective cesarean section. The cord blood TBA concentration was investigated by enzyme method and the cord concentration of cortisol and DHEA-S by radioimmunoassay. Results The cord TBA concentration in ICP group was significantly higher than that of controls [(8.93?3.16)mmol/L vs (4.33?1.51)mmol/L, P0.05)]. The cord blood level of cortisol,DHEA-S and the ratio of DHEA-S over cortisol were correlated with the cord blood TBA concentration (r 1= 0.87,r 2=-0.88,r 3=-0.84,P

Objective To summarize the experience of liver retransplantation, as well as the factors i nfluencing the surgical effects. Methods The clinical data of 8 patients who received liver retransplantation in our cent er were analyzed retrospectively. Results Among 8 cases, complications of biliary tract occurred in 5 cases, chronic rejec tions in 2 cases, embolism in hepatic artery in one case. Infections occurred in 7 cases before engraftment. Case 1 had develope d renal function failure before the surgery, and he died of severe infections an d multi-organ failure after transplantation. Case 4 had massive hemorrhage duri ng the operation and also died of multi-organ failure after transplantation. Case 7 developed in tracanial hemorrhage and abdominal infection and died early after transplantatio n. Other 5 cases has recovered and left hospital. Conclusions Liver retransplantation is the only measure that can be taken to save the lives of patients whose liver allograft fails to function. It's very important that the indications and time of retransplantation should be carefully selected. Factors that may lead to harmful effects on liver retranspl antation include bad preoperative condition of the recipient, tough and long ope ration, massive hemorrhage during the operation, and severe complications after the surgery.

Acute and chronic graft rejection are the major factors leading to graft non-function.There is an active expression of chemokines early after transplantation.They recruit T cells and antigen presenting cells selectively to the graft, leading to inflammatory reaction and finally to graft non-function.Accordingly,monitoring the expression status of chemokines and their receptors regularly may help to the diagnose rejection.To determine one or more chemokines or their receptors as the new targets for anti-rejection therapy will be of great clinical significance.This review focuses on the research progression in the above areas.

Objective: To study the role of mechanical stress on osteoblast-like characteristics expressed by human periodontal ligament cells in vitro. Methods: Human periodontal ligament cells (hPDLC) were cultured by explant method. We investigated the gene expression for osteoblast-like marker proteins in periodontal ligament stimulated by cyclical mechanical force in vitro by in situ hybridization with non-radioisotopic oligonucleotide probe for alkline phosphatase (ALP) and osteocalcin (OCN). Results: Human periodontal ligament cells exhibited a stronger signal for ALP mRNA stimulated by cyclical mechanical force, and exhibited a moderately intense positive signal for OCN mRNA—OCN was a marker of differentiated osteoblast-like cells. Conclusion: These findings suggest that mechanical force plays role in differentiation from hPDLC to osteoblast-like cells.
