Objective To study the effect of delayed cyclosporine(CsA) therapy combined with prophylactic use of antilympho-cyte globulin (ALG) (sequential quadruple immunosuppressive protocol) on early graft function in renal transplantation. Methods The experimental group included 90 renal recipients who were treated with posttransplant quadruple sequential therapy. Their short-term outcomes were compared with those of 215 recipients who were given CsA immediately after transplantation(control group). Results Not only was the recovery of renal allograft function faster in the experimental group ( P 0. 05). Conclusion Delayed CsA therapy in conjunction with prophylactic use of ALG is a desirable protocol for treating posltransplant renal recipients.

Objective To examine the levels of CD38+CD8+ T lymphocyte in kidney transplant recipients with cytomegalovirus infection and investigate the possibility in monitoring the cytomegalovirus active infection after kidney transplantation. Methods Before and after kidney transplantation, CD38+ CD8+T lymphocyte and cytomegalovirus leucocyte antigen were measured respectively by flow cytometry and immunohistochemistry method in 56 transplant recipients. The data of CD38+CD8+ T lymphocyte and the cylomegalovirus leucocyte antigen were analyzed. Results Before kidney transplantation, cytomegalovirus leucocyte antigen was negative among all the patients, while the mean ratio of (CD38+CD8+)/CD8+ was 0. 11?0. 05. In 14 recipients whose cytomegalovirus leucocyte antigen was positive, the appearing time of the positive antigen was(32. 7?16. 6) days of post-transplantation, meanwhile, the mean ratio of (CD38+ CD8+)/CD8+ was 0. 43?0. 21 (29. 6?8. 4) days of post-transplantation, which was significantly higher than that of pre-transplantation. After the treatment with ganciclovir intravenously, the cytomegalovirus leucocyte antigen became negative and the mean ratio of (CD38+CD8+)/CD8+ decreased to 0. 16?0.09 which was significantly lower than that of pre-treatmmt ( P

AIM　To discuss the intraspecific relationship in Magnolia officinalis and the genuineness of Cortex Magnoliae officinalis, and to find some DNA characters of certified “Houpo”. METHODS　Thirty-three samples from eleven locations, which can represent most of the distribution of M.officinalis, were selected. The total DNA was extracted. Severty-four random primers were tried to get good amplification. RESULTS One hundred and sixteen bands amplified from seventeen primers, were clustered by NTSYS-pc software. Three branches were obtained. Some distinctive primers and bands, which represent certified species or fine breed, were obtained also. CONCLUSION　1) M.officinalis should be divided into three geographic clans instead of two subspecies or varieties, they are, a) typical officinalis, b) typical biloba and c) Middle type. This conclusion agrees with the leaf form and other characters. 2) The genetic difference between “Chuanpo” and “Wenpo” is evident and the difference is in correspondence with the quantities of their chemical constituents. So, the genetic difference is the main reason of the genuineness of Cortex Magnoliae officinalis. 3) These results may be used to establish DNA database for identification of Cortex Magnoliae officinalis.

【Objective】To investigate the role of mycophenolate mofetil (MMF) in the prevention of acute rejection in renal transplantation.【Methods】A total of 106 patients were randomized into two groups.One group received MMF (n=56),the other received azathioprine (Aza) (n=50).The time of the following study was within the first 6 months after transplantation.【Results】The rate of acute rejection of group receiving MMF was 20%,it′s lower than that of the group receiving Aza 44% (P<0.01).The recovery rate of acute rejection treated by methylprednisolone (MP),in MMF group 82% was higher than Aza group 55%.(P<0.05).Meanwhile the hepatotoxicity as well as cytomegalovirus (CMV) infection were lower in MMF group than those in Aza group.【Conclusion】MMF as a new anti-rejection drug could more effectively prevent acute rejection than Aza after renal transplantation,and has lower toxicity and side effect.

Objective To test our hypothesis that sensitivity to avian influenza A(H5N1)virus varies among mouse strain backgrounds, we compared the pathogenicity of H5N1 viral infection in 5 mouse strains. Methods Onehundred-fifty mice from 2 inbred strains(BALB/c and C57BL/6), and 3 outbred stocks(ICR, NIH Swiss, and KM Swiss)were used. Thirty mice of each strain were subjected to an infected group(20 mice), in which mice were inoculated with 0. 1 mL(104.875 TCID50)of A/Goose/Guangdong/NH/2003(H5N1)virus intra-nasally; ten control mice received noninfectious allantoic fluid. Clinical signs were assessed daily for 14 days post-infection. Necropsy was performed on mice that died during the experiment and those euthanized at end of study. Tissue samples were collected for viral isolation and pathological analysis. Results H5N1 virus infection can cause respiratory illness in all 5 strains with severe or minor acute respiratory distress symptoms, but with different mortality rates: 70% in BALB/c; 50% in ICR; 40% in NIH Swiss; 25% in C57BL/6; and 10% in KM Swiss mice. Necrotizing interstitial pneumonia was found in all cases of death. The virus was isolated from the lungs of all infected dead mice. Conclusion A/Goose/Guangdong/NH/2003 (H5N1)virus can infect all mouse strains used in this study, and can cause clinical symptoms and pathological changes similar to those found in humans infected with HSN1 viruses. However, the pathogenicity of H5N1 viral infection varies significantly between the different mouse strains. Thus, in future study of H5N1 virus infections the mouse strain most relevant to their particular research purpose should be selected as animal model.

Objective:To retrospectively assess the relationship between immune disorder and acute gastrointestinal injury (AGI) in patients after severe polytrauma.Methods:Totally 205 patients with severe polytrauma admitted to Tongji Hospital from April 2018 to October 2019 were enrolled as the observation group, and 23 healthy volunteers were served as the control group. According to the diagnostic criteria of AGI, all patients were divided into the AGI group (with AGI) or N-AGI group (without AGI), AGI patients were divided into the S-AGI group or L-AGI group according to the severity. The levels of cytokines and lymphocyte subset were evaluated at day 1, 7, and 14 after severe polytrauma. The differences between groups were statistically analyzed. The independent risk factors of AGI were analyzed by Logistic regression analyzed.Results:Totally 79.5% (163/205) of patients with severe polytrauma were accompanied by AGI. There were significant differences in the ratio of Tc, Th at day 1 after trauma, the levels of IL-6, TNF-α, IL-8, IL-10, the ratio of Ts, Th/Ts, Treg at day 7 after trauma, and the levels of IL-8, IL-10,the ratio of Ts, Th/Ts, Treg at day 14 after trauma between the AGI group and N-AGI group ( P<0.05). There were significant differences in the ratio of Tc, Th, the levels of IL-6, TNF-α at day 1 after trauma and the ratio of Ts, Th/Ts, Treg, the levels of IL-8, IL-10 at day 7 and 14 after trauma between the S-AGI group and L-AGI group ( P<0.05). Logistic regression analysis showed that Ts 7 d ( OR=2.018, 95% CI: 1.105-5.364, P=0.013), Treg 14 d ( OR=3.612, 95% CI: 1.375-8.476, P=0.006), IL-6 7 d ( OR=1.824, 95% CI: 1.011-5.835, P=0.024), IL-10 14 d ( OR=2.847, 95% CI: 1.241-6.216, P=0.014), TNF-α 7 d ( OR=1.754, 95% CI: 1.215-5.441, P=0.018) were independent risk factors in patients with AGI after severe polytrauma. Conclusions:AGI is more easily occurred in patients with the heavier immune disorders after severe polytrauma. AGI can also aggravate pre-existing immune disorders in patients after severe polytrauma.

Objective To investigate the clinic significance of intracranial pressure (ICP)monitor for operation of hy-pertensive cerebral hemorrhage. Methods Fifty-eight patients suffering from hypertensive cerebral hemorrhage from Jan 2011 to Nov 2012 were included,and were divided into two groups,ICP-monitor group(A group) and non-ICP-moni-tor group(B group). The clinic data of all patients were statistically analyzed and the prognosis was evaluated with six-month follow up period after operation. Results Compared with patients who had ICP monitor post operation, the inci-dence of distance of water and electrolyte reduced significantly in A group; Moreover,the scores of GOS were signifi-cant higher in A group. Nevertheless,there was no significant difference on operative mortality between two groups af-ter operation 14 days. Conclusion The study demonstrates that ICP monitor can guide the clinical therapy,decrease the incidence of complication and improve the prognosis for patients suffered from operation of hypertensive cerebral hem-orrhage.
