腹泻型肠易激综合征患者结肠黏膜组织异常表达蛋白质的筛选与鉴定

目的 筛选及鉴定腹泻型肠易激综合征(D-IBS)患者与正常人结肠黏膜组织中的差异表达蛋白.方法 D-IBS患者及健康志愿者各4例,分别为D-IBS组和正常对照组.通过结肠镜取回盲部及乙状结肠黏膜进行活检,用含0.1% PMSF的冰盐水将标本洗净后立即置于液氮中保存.提取蛋白质,采用双向凝胶电泳法筛选差异表达蛋白,并采用质谱法对变化最明显的蛋白点进行鉴定.结果 利用双向凝胶电泳技术成功得到人结肠黏膜组织的蛋白质组图谱.正常对照组图谱平均得到蛋白点336个,组内图像平均匹配率92%,D-IBS组图谱平均得到蛋白点426个,组内图像平均匹配率95%.D-IBS组与正常对照组之间进行平均胶图谱的比较,两组间匹配率为74%.Volume值变化大于2倍以上的点共24个,其中21个点表达上调,3个点表达下调.表达上调最明显的2个蛋白点经鉴定分别为免疫球蛋白J链(Ig-j)和热休克蛋白27(HSP27),表达下调最明显的2个蛋白点则分别为血红蛋白β亚基和果糖二磷酸醛缩酶A.结论 采用双向凝胶电泳法可以成功得到人结肠黏膜组织蛋白质组表达图谱,D-IBS患者与正常人结肠黏膜组织蛋白质表达存在差异,已经鉴定出来的4个蛋白可能在D-IBS的发病机制中起一定作用.     

Infection dynamics and virus-induced apoptosis in cell culture-based influenza vaccine production—Flow cytometry and mathematical modeling

Cell culture-based influenza vaccine manufacturing is of growing importance. Depending on virus strains, differences in infection dynamics, virus-induced apoptosis, cell lysis and virus yields are observed. Comparatively little is known concerning details of virus–host cell interaction on a cellular level and virus spreading in a population of cells in bioreactors. In this study, the infection of MDCK cells with different influenza A virus strains in lab-scale microcarrier culture was investigated by flow cytometry. Together with the infection status of cells, virus-induced apoptosis was monitored. A mathematical model has been formulated to describe changes in the concentration of uninfected and infected adherent cells, dynamics of virus particle release (infectious virions, hemagglutinin content), and the time course of the percentage composition of the cell population.     

Plasma Concentrations of Mycophenolic Acid Acyl Glucuronide Are Not Associated with Diarrhea in Renal Transplant Recipients

The aim of this study was to determine whether plasma concentrations of the acyl (AcMPAG) and phenolic (MPAG) glucuronide metabolites of mycophenolic acid (MPA) were related to diarrhoea in renal transplant patients on mycophenolate mofetil (MMF) with cyclosporine (CsA) or tacrolimus (TCL). Blood samples (0, 30, 120 min) were taken at days 3, 10, week 4, months 3, 6 and 12 for determination of MPA, MPAG and AcMPAG. MPA-AUC was estimated using validated algorithms. Two hour AUCs were calculated for MPAG and AcMPAG. Immunosuppressive therapy consisted of CsA/MMF (n= 110) and of TCL/MMF (n= 180). In 70/290 (24%) patients 86 episodes of diarrhoea were recorded during 12 months. Significantly more patients on TCL (31.1%) suffered from diarrhea compared to CsA (12.7%). MMF dose, MPA-AUC and the 2 h AUCs of MPAG and AcMPAG did not differ between patients with and without diarrhoea. Plasma AcMPAG and MPAG concentrations were substantially higher in patients on CsA compared with TCL, while MPA-AUC was lower in the former group. These data support the concept that CsA inhibits the biliary excretion of MPAG and AcMPAG, thereby potentially reducing the risk of intestinal injury through enterohepatic recycling of MPA and its metabolites.     

Weighted Markov chains for forecasting and analysis Incidence of infectious diseases in jiangsu Province,China

This paper first applies the sequential cluster method to set up the classification standard of infectious disease incidence state based on the fact that there are many uncertainty characteristics in the incidence course.Then the paper presents a weighted Markov chain,a method which is used to predict the future incidence state.This method assumes the standardized self-coefficients as weights based on the special characteristics of infectious disease incidence being a dependent stochastic variable.It also analyzes the characteristics of infectious diseases incidence via the Markov chain Monte Carlo method to make the long-term benefit of decision optimal.Our method is successfully validated using existing incidents data of infectious diseases in Jiangsu Province.In summation,this paper proposes ways to improve the accuracy of the weighted Markov chain,specifically in the field of infection epidemiology.     

胆源性感染性休克兔血栓素、前列环素与血小板聚集率的变化

动态观察胆总管急性完全性梗阻并感染、继发休克兔的血浆血栓素(TXA_2)和前列环素(PGI_2)的稳定代谢产物 TXB_2和6-keto-PGF_(1α)含量及血小板聚集率的变化。结果,血浆 TXB_2呈进行性升高,20h 后(休克时)呈下降趋势,血浆6-keto-PGF_(1α)6h 升高,随后回降;血小板聚集率呈进行性下降。提示血栓素和前列环素、血小板聚集率的变化在重症急性胆管炎、胆源性感染性休克发病过程中起重要病理生理作用,与病情和预后转归有重要联系。
