CO2跨临界循环系统润滑油分析

为保证CO2跨临界循环系统的稳定运行，选择与之相适应的润滑油，在分析摩擦润滑特性的基础上，采用实验数据对比的方法，对POE、PAG、PAO和烷基芳香烃4类合成润滑油在CO2跨临界循环系统中的混合性、流动性、可溶性、黏度、长期稳定性及润滑性等性能进行了分析，结果表明POE类润滑油是CO2跨临界循环系统的一种相对较好的选择。     

乙酰胆碱对人胃粘膜上皮细胞和胃腺癌细胞内Ca2+、Mg2+浓度的影响

目的:探讨乙酰胆碱对人胃粘膜上皮细胞和胃腺癌细胞内Ca2 、Mg2 浓度的影响。方法:利用大型生化分析仪,检测了乙酰胆碱作用后培养的人胃粘膜上皮细胞和胃腺癌细胞内Ca2 、Mg2 的浓度。结果:与正常胃粘膜上皮细胞比较,胃腺癌细胞内Ca2 、Mg2 浓度偏低(P>0 01)。在乙酰胆碱作用下,胃粘膜上皮细胞内Ca2 浓度升高(P<0 01),Mg2 浓度降低(P<0 01);胃腺癌细胞仅有Ca2 浓度升高(P<0 05),Mg2 浓度无变化。阿托品能阻断乙酰胆碱的作用(P<0 05)。结论:乙酰胆碱对胃粘膜上皮细胞和胃腺癌细胞的作用是通过毒蕈碱受体实现的。     

不饱和烃同系物凝聚型物理性质递变规律的数学描述

以H-(CH2)n-CH=CH2和H-(CH2)n-C≡CH型同系物结构重复单元数值连续变化为模型,获得了描述该同系物凝聚型物理性质递变规律的数学表达式:P=(a0+a1n+a2n2)/(1+b2n2),式中a0、a1、a2、b2均为常数,n为结构重复单元数值,P为同系物的凝聚型物理性质。通过非线性回归分析,得到回归方程,结果表明同系物的凝聚型物理性质与重复结构单元数值之间满足上述关系式,并显示优良的相关性。

DEGREE CONDITIONS FOR GRAPHS TO BE FRACTIONAL （a, b, n）-CRITICAL GRAPHS

Let G be a graph, and a and b be integers with a ≤ b. A graph G is called a fraetional （a, b, n）-critical graph if after any n vertices of G are deleted the remaining subgraph has a fractional [a, b]-factor. In this paper two degree conditions for graphs to be fractional （a, b, n）-eritical graphs are presented, and the degree conditions are sharp in some sense.

Science Letters： A synthetic Toll-like receptor 2 ligand decreases allergic immune responses in a mouse rhinitis model sensitized to mite allergen

It has been proposed that activation of Toll-like receptors （TLRs） plays crucial roles in the polarization of adaptive immune responses. A synthetic Toll-like receptor 2 （TLR2） ligand, Pam3CSK4, has been reported to modulate the balance of Th1/Th2 responses. We evaluated the modulation effect of Pam3CSK4 on allergic immune response in a mouse rhinitis model sensitized to house dust mite allergen （HDM）. Mice were sensitized and challenged with Dermatophagoidesfarinae allergen （Der f）, and then the allergic mice were treated by Pam3CSK4. Nasal allergic symptoms and eosinophils were scored. Der f-specific cytokine responses were examined in the splenocytes and bronchoalveolar lavage fluid （BALF）. Serum level of total IgE was also detected. After establishing a mouse allergic rhinitis model with HDM, we have showed that Pam3CSK4 treatment not only ameliorated the nasal allergic symptoms remarkably but also decreased the eosinophils and total inflammation cells in BALF significantly. Analysis of cytokine profile found that IFN-7 released from either BALF or stimulated splenocytes increased markedly in Pam3CSK4-treated mice, while IL-13 decreased significantly. Moreover, serum level of total IgE was significantly lower in Pam3CSK4-treated mice than in the untreated. Thus, in an allergic rhinitis mouse model developed with HDM, Pam3CSK4 was shown to exhibit an antiallergic effect, indicating its potential application in allergic diseases.
