血清脂蛋白(a)联合血脂指标检测对冠心病的诊断价值

目的：探讨脂蛋白ａ「ＬＰ（ａ）」与血清中脂质项目联合检测对冠心病（ＣＨＤ）诊断价值。方法：分别用ＥＬＬＳＡ法、免疫比浊法、酶法对ＬＰ（ａ）、ＬＤＬ－Ｃ、ａｐｏＢ１００和ＴＣ、ＴＧ进行检测。结果：实验组与对照组相比,除ＴＣ、ＴＧ外各指标均有明显差异（Ｐ〈０．０５）。单项指标对诊断ＣＨＤ的敏感性、特异性、阳性预测值、诊断效率仅分别为３６％、８５％、８０％、５３％。将ＬＰ（ａ）与ＬＤＬ－Ｃ、ａｐｏＢ１０     

Changes of erythrocyte membrane ATPase activities and plasma lipids in patients with coronary heart disease]

Fasting plasma triglyceride (TG), total cholesterol(TC), low density lipoprotein-cholesterol(LDL-C), high density lipoprotein-cholesterol(HDL-C), activities of erythrocyte membrane Na(+)-K(+)-ATPase, Ca(2+)-ATPase, Mg(2+)-ATPase, and intraerythrocytic calcium concentration were examined in 21 patients with coronary heart disease(CHD) and 21 normal controls. It was found that the plasma contents of TG, TC, LDL-C and intraerythrocytic [Ca2+] in patients with CHD were much higher while plasma contents of HDL-C, activities of erythrocyte membrane Na(+)-K(+)- and Ca(2+)-ATPase were much lower than those of normal controls. Mg(2+)-ATPase activity showed no significant difference between these two groups. The activities of erythrocyte membrane Na(+)-K(+)- and Ca(2+)-ATPase were negatively correlated with plasma TG, TC, LDL-C levels, respectively, and positively correlated with plasma HDL-C. The possible pathogenic mechanism is discussed on the basis of our results.     

肠三叶因子在大鼠肠道中表达的实验研究

目的 研究肠三叶因子（ＩＴＦ）及其ｍＲＮＡ大鼠肠道的分布规律。方法 采用原位杂交、免疫组化等手段观察了ＩＴＦ及ＩＴＦｍＲＮＡ在大鼠肠道的表达并使用高效液相色谱仪检测了不同肠段ＩＴＦ的含量。结果 从十二指肠至结肠均有ＩＴＦ及ＩＴＦｍＲＮＡ表达，主要分布于肠绒毛杯状细胞，其中ＩＴＦｍＲＮＡ仅在杯状细胞的基底和边缘表达，其它区域的杯状细胞则呈ＩＴＦｍＲＮＡ阴性反应，同时发现部分其它部位的肠上皮细胞中亦有     

薯蓣皂苷元无定形固体分散体制备及体内外评价

目的 制备薯蓣皂苷元无定形固体分散体（diosgenin amorphous solid dispersion,Dio-ASD），提高Dio溶出度和生物利用度。方法 应用分子模拟技术分析Dio与载体之间相互作用并通过抑晶实验验证，构建Dio与载体混溶性曲线相图，理论预测二者混溶性；以Soluplus为载体，应用共沉淀法制备Dio-ASD；通过溶出度测定、差示扫描量热分析（differential scanning calorimetry,DSC）、X-射线粉末衍射（X-ray powder diffraction,XRPD）、扫描电镜分析（scanning electron microscopy,SEM）、傅里叶红外光谱（Fourier transform infrared spectroscopy,FT-IR）对Dio-ASD进行体外评价；采用UPLC-MS/MS方法测定大鼠体内Dio血药浓度，计算药动学参数，对Dio-ASD进行体内评价。结果 分子模拟结果显示Soluplus与Dio之间能形成疏水键和氢键相互作用，结合能强于其他载体，且Soluplus对Dio的抑晶作用最强。构建了...     

Increased virulence using engineered protease-chitin binding domain hybrid expressed in the entomopathogenic fungus Beauveria bassiana

Insect cuticles consist mainly of interlinked networks of proteins and the highly insoluble polysaccharide, chitin. Entomopathogenic fungi, such as Beauveria bassiana, invade insects by direct penetration of host cuticles via the action of diverse hydrolases including proteases and chitinases coupled to mechanical pressure. In order to better target cuticle protein-chitin structures and accelerate penetration speed, a hybrid protease (CDEP-BmChBD) was constructed by fusion of a chitin binding domain BmChBD from Bombyx mori chitinase to the C-terminal of CDEP-1, a subtilisin-like protease from B. bassiana. Compared to the wild-type, the hybrid protease was able to bind chitin and released greater amounts of peptides/proteins from insect cuticles. The insecticidal activity of B. bassiana was enhanced by including proteases, CDEP-1 or CDEP:BmChBD produced in Pichia pastoris, as an additive, however, the augment effect of CDEP:BmChBD was significantly higher than that of CDEP-1. Expression of the hybrid protease in B. bassiana also significantly increased fungal virulence compared to wild-type and strains overexpressing the native protease. These results demonstrate that rational design virulence factor is a potential strategy for strain improvement by genetic engineering.
