Objective To investigate the efficacy and safety of anti CD25 Ab (Zenapax;Daclizumab) induction therapy in 62 patients following renal transplantation. Methods Sixty-two renal transplant recipients treated with Daclizumab induction therapy were analyzed retrospectively from Sep. 1999 to May 2004. Main immunosuppressive therapy regimen consisted of steroids cyclosporine and mycophenolate mofetil in all recipients after operation. According to Daclizumab dosage, these recipients were divided into 1-dose group, 2-dose group and over 2-dose group. All patients received Daclizumab 1 h before operation.Results The patients subject to Daclizumab were followed up from 3 months to 57 months. Seven of them had acute rejection ( 11.3 %) at intervals for 10.3 months, from 2 months to 14 months. Patient who had acute rejection at 10th month after operation lost his graft at 13th month after transplantation for graft dysfunction. The incidence of acute rejection was 15.6 % among 45 patients followed up over 12 months. Conclusions Induction therapy of Daclizumab could decrease the incidence of acure rejection, delay the time of acute rejection and relieve the severity of rejection. More graft can be long-survival. We can lower the dosage of CsA effectively and safely after induction of Daclizumab.

Objective To compare the graft function of 2 methods of kidney harvesting,the modified method of combined liver and kidney procurement and rapid en bloc kidney procurement. Methods The clinical data of 220 cadaveric renal transplantation recipients were collected(12 months follow-up),174 cases from en bloc kidney procurement and 46 from combined liver and kidney procurement.The average harvesting time,the incidence of renal vein injury,1 year kidney survival and incidence of acute rejection were compared between the two methods.Results In average harvesting time and incidence of renal vein injury,the en bloc kidney procurement were better than the method of combined liver and kidney procurement.However,the method of combined liver and kidney procurement was better than the en bloc kidney procurement in 1 year kidney survival,1 year incidence of acute rejection and average warm ischemia time.There was no difference in 1 year survival of patients and 24 h,1 week and 1 year graft function after transplantation. Conclusion Although the method of combined liver and kidney procurement is better than the en bloc kidney procurement in 1 year kidney survival and 1 year incidence of acute rejection,there is no difference between the 2 methods in 1 year survival of patients and graft function after transplantation.

In order to compare the characteristics of ethano l production, a serie s respiratory deficient mutants (rho -) of Saccharomyces cerevisiae and the ir wil d parent strain (rho +) were assayed for ethanol yield, ethanol fermentation ki netics, ethanol tolerance, and activities of ethanol-dehydrogenase. The data i nd icated that: Though the average amount of ethanol produced by mutants rho - a nd by wild rho + strains were similar, some mutants produced a little more amount of ethanol than wild type. The kinetics curve of ethanol fermentation suggested t h at rho - mutants had a little higher ethanol fermenting speeds than wild type . Th e activity of ethanol-dehydrogenase per unit weight of protein of rho - mutan ts c ells were higher than that of wild strain rho +; the activity of ethanol-dehyd rogenase per unit volume of fermentation medium of rho + were higher than that rho - mutants,mainly due to the higher biomass of rho + were higher than that of rho - mutan ts. Some rho - mutants could tolerate higher ethanol concentration than wild rh o + stra in, but some not. If higher ethanol tolerance and higher ethanol yield rho - mu tants were used in fermenting process,higher ethanol yield would be expected,but some problems such as that rho - mutants grew slowly should be considered.

G protein coupled receptors (GPCRs) are transmembrane receptor proteins, which allow signals to transfer across membrane. GPCRs include a large number of receptors, different receptors mediated different signaling pathways of GPCRs- adenylyl cyclase (AC)- cyclic adenosine 3' ,5'-monophosphate (cAMP), including β2 adrenergic receptors (β2- ARs)- AC- cAMP signaling pathways, E-prostanoid2/4 (EP2/4)-AC-cAMP signaling pathways. Regulatory proteins, such as G protein coupled receptor kinases (GRKs) and β-arrestins, play important modulatory roles in GPCRs signaling pathway. GPCRs signaling pathway and regulatory proteins implicate the pathogenesis process of inflammatory and immune response. Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis and accompanied with inflammatory and abnormal immune response. This article review the advances on GPCRs signaling pathway implicating in the inflammatory and immune response of RA.

3T3-L1 adipocytes transfected with TSH receptor (TSHR) shRNA were incubated with bovine TSH.The concentration of tumor necrosis factor (TNF)-α in culture medium was measured by enzyme linked immunosorbent asssy.Protein level of insulin receptor substrate 1 (IRS-1) was quantified by Western blotting.Tyrosine phosphorylation of IRS-1 was measured by immunoprecipitation.The results showed that 1 mIU/ml TSH significantly sitmulated TNF-α release in 3T3-L1 adipocytes [(341.85 ± 12.00 vs 522.67 ± 36.22) ng/L,P<0.01],along with the decreases in IRS-1 protein expression and its tyrosine phosphorylation (P< 0.01).These effects disappeared when TSHR expression was down-regulated with RNA interference in 3T3-L1 adipocytes.In addition,WP9QY,a TNF-α antagonist,blocked TSH-decreased IRS-1 expresssion.These results suggest that TSH downregulates IRS-1 protein expression and its tyrosine phosphorylation through stimulating production of TNF-α,and thus contributes to the development of insulin resistance.

[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P<0.01),as well as higher diabetic nephropathy incidence (P<0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 % CI 1.195-3.586).
