Objective: Through the study on the expression and their clinical significance of co-stimulatory molecules CD40, PD-L1, B7-H3, CD3 and cytokine IL-6 in the skin lesions of neurodermatitis patients, in combination with the pathological changes in the skin lesions, the immunolopathological mechanism of neurodermatitis were investigated in order to find the new target molecule of immune intervention.

目的： 通过研究共刺激分子CD40，PD-L1，B7-H3及CD3分子、细胞因子IL-6在神经性皮炎皮损组织中的表达，结合皮损组织的病理形态改变，从而探讨神经性皮炎发生的免疫病理机制及其寻找新的免疫干预的靶分子。

It has the ability to neutralise harmful molecules produced in skin exposed to UV rays.

The metalloproteins which are widely distributed in vivo are very important target molecules of NO. A new Y/〓 reaction system which can form Y-NO bond has been established and has been used to measure the NO affinity of metalloporphyrins as metalloprotein models. Three kind of bond energies of the Co-NO bonds in series of cobalt nitrosyl tetraphenylporphyrins have been determined by thermodynamic cycles combined with calorimetric measurements and relevant electrochemical data.

本文以金属卟啉模拟体内重要的NO靶分子金属蛋白，通过确立新的适于量热和电化学测定的Y／〓成Y-NO键反应体系，利用合适的热力学循环，建立了新的适于金属卟啉体系的NO亲合势的测定方法，得到了苯腈中系列亚硝基四苯基钴卟啉Co-NO键的键能，即钴卟啉NO亲合势的定量标度，以表征钴卟啉的NO结合能力。

Abstract］ To investigate the mechanism of reception and transmission of immune molecules in vagus, the expression of IL-1 receptor type Ⅰ in nodose ganglion and vagal paraganglion was studied by using immunohistochemistry.

摘要］ 为研究迷走神经感受和传递免疫信息的机制，用免疫组织化学方法研究了IL-1Ⅰ型受体在正常和免疫激活的大鼠结状神经节和迷走旁节中的表达。

Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.
