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.

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.

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.

AIM　To investigate the effect of hydroxyl camptothecinum(HCPT) on pharmocokinetics of cyclosprine A(CsA) and the membrane lipid fluidity (LFU)of red cell in rabbits. METHODS　The whole blood concentration of CsA in rabbits was monitored using method of FPIA. The LFU of red cell was measured using method of DPH fluorescence polarization technique. RESULTS　The pharmocokinetic parameters of CsA in group CsA+HCPT such as a,V(c),K12 and CL(s) were significantly lower and T1/2(a) was significantly higher (P<0.05) than in group CsA. The concentration of CsA of group CsA+HCPT was higher after injection 0.25, 0.5 and 1.0 h, but have significantly high at 1.0 h point (P<0.05). After injection 0.5,1.0, 1.5 h the LFU of red cell in group CsA+HCPT was higher than in group CsA (P<0.05). The LFU in group CsA was lower that in control at 0.5,1.0 and 1.5 h point (P<0.05). CONCLUSION　HCPT can enhance the whole blood concentration of CsA in rabbits. CsA administrated with HCPT is feasible.

Objective To find out the risk factors of early pulmonary infections after renal transplantatioa Methods The data were collected from 96 patients receiving renal transplantation between Oct. 2006 and Oct 2010, including 48 cases of early lung infection after renal transplantation as infection group, and 48 patients receiving immunosuppressive regimen at the same period as-control group. Taking the factors of lung infecition as variables, t test or chi-square test was used in univariate analyses whereas logistic regression was used in multivariate analyses. Results Single factor analysis showed that induction therapy, albumin levels, dose of steroid in 1 month after operation,family income and prophylactic SMZ treatment were related to lung infectioa Analysis of multiple variables logistic regression revealed that induction therapy, albumin levels, dose of steroid in 1 month after operation and prophylactic SMZ treatment were related to lung infection. Conclusion The correlation analysis indicated that induction therapy and dose of steroid in 1 month after operation have positive correlations with pulmonary infection, while albumin levels and prophylactic SMZ treatment have negative correlations with pulmonary infection.

Objective To observe the effect and safety of treating senile abnormal lipid metabolism with LU Zhi-zheng's dampness-removing,turbid-resolving and heart-communicating formula.Methods 60 patients were randomly divided into a treatment,treated with LU's formula,one dosage per day,and a control group,treated with gypenosides,60mg/tablet,three times per day,with 30 patients in each group.Both groups were treated two therapeutic courses,which were 8 weeks.Results Except HDL-C,other indexes including TC,TG,LDL-C in the treatment group were all obviously improved after the treatment [the statistical values were (5.81 ± 1.70) mmol/L,(3.05±2.30) mmol/L,(3.39± 1.11 ) mmol/L respectively,P＜0.01 or 0.05],which were also better than the control group [the statistical values were ( 6.16 ± 1.91 ) mmol/L,( 3.03 ± 1.89 ) mmol/L,(3.81±0.63) mmol/L,P＜0.01 or 0.05].Symptoms improvement such as chest oppression,dizziness,heaviness of head,headache,sticky mouth without thirsty,constipation,nausea and vomiting,and heaviness of limbs in the treatment group were also better than the control group,with mean rank were 23.83、38.10、36.10、34.70、36.77、39.82、33.38、34.17 respectively.No abnormal changes were found in indexes of blood routine,urinary routine,stool routine,ECG,ALT,AST and Cr.Conclusion LU Zhi-zheng's dampness-removing,turbid-resolving and heart-communicating formula improved clinical symptoms and signs of abnormal lipid metabolism patients,its therapeutic effects were better than gypenosides.
