The oversaturation of cholesterol in bile results in the formation of cholesterol stones. The liver is the organ which synthesizes cholesterol and secretes bile. Liver lipid metabolism research helps to explain the mechanism of cholelithiasis. Utilizing biochemical and biomolecular technology, we have done experimental work as follows: Analyse the ingredient changes of blood and bile samples from patients.

肝脏是合成胆固醇、分泌胆汁酸的器官，对肝脏胆固醇代谢的研究有助于阐明胆石症形成的原因，本文用生物化学和分子生物学的方法，分析了病人血液、胆汁中各种脂类成份的变化，以及肝脏胆固醇合成限速酶3-羟-3-甲戊二酸辅酶A还原酶（HMG-CoA Reductase）、胆汁酸合成限速酶7α-羟化酶（7α-hydrolase）的基因表达。

The UV absorption and photoluminescence properties of phenanthroline derivatives with triphenylamine and oxadiazole groups and their europium complexes were investigated. These europium complexes display intense UV absorption and photoluminescence properties. The PL results from emission of Eu3+ ion in their pure thin films. A maximum PL wavelength is 612 nm and a full width at half maximum is from 9 nm to 15 nm for the PL of these europium complexes, respectively.

2研究了三芳胺和噁二唑功能化的邻菲罗啉中性配体及其铕配合物的紫外吸收和光致发光性能，研究结果表明，这类新型的铕配合物具有强烈的紫外吸收和光致发光性能，铕配合物在固体薄膜状态下都能发射出强烈的铕离子特征峰，其最大发射波长为612 nm，半峰宽为9～15 nm。

In a DMF solution of CuCl〓-ethanolamine-acetic acid (1: 2: 2), 27 formed a highly oxidized heterocyclic compound 2-hydroxymethyl-naphtho [1, 2-a] oxazole (30) by the carbon-nitrogen coupling and carbon-oxygen coupling with the ligand of ethanolamine, which brings a chance to develop a novel approach to this heterocyclic compound via one-pot reaction of phenols under mild condition.

在氯化铜—乙醇胺—乙酸（1：2：2）的DMF溶液中，27与配体乙醇胺发生碳氮偶合与碳氧偶合，生成深度氧化的杂环化合物：2-羟甲基-萘并[1，2-a]〓唑（30）。这可望为酚类一锅化直接转化为30及其类似物提供一种简便的新合成路线。

Chronicity maybe result from many factors with complex mechanism.HCV may evade the host immune surveillance due to the hypermutation of HCV gene; HCV has the nature of pantropic,the tissues outside liver can provide virus for repeatedly infection of liver; The HCV receptors,such as CD81,LDL receptor,scavenger receptor B type I,L-SIGN,DC-SIGN and so on,may influence organism humoral immunity and the cellular immunity function in different degrees; HCV infection also may cause the reduction of quantity of organism immune cell or functional defect,low response of humoral immune response,tolerance of cellular immunity,then,the host finally transforms into chronic infection condition.

其慢性化的机制非常复杂，是由多个因素造成的，HCV因其基因高变性可以逃避宿主的免疫监视；HCV具有泛嗜性，肝外组织又可为肝组织的反复感染提供病毒来源；CD81、LDL受体、清道夫受体B类Ⅰ型及L-SIGN、DC-SIGN等HCV受体又可不同程度地影响机体的体液免疫和细胞免疫功能；HCV感染亦可直接导致机体免疫细胞数量减少或功能缺陷，体液免疫应答水平低下、细胞免疫耐受，宿主最终转变为慢性感染状态。

These clinical data suggest that any manifestations similiar to pulmonary interstitial fibrosis complicated with pleural effusion and paratracheal lymphadenopathy should be further differentiated from PLC by HRCT and pleural-lung tissue biopsy.

对双肺呈类间质纤维化改变，同时合并胸腔积液和纵隔淋巴结肿大的患者，应进一步行高分辨CT及胸膜肺组织病理活检，以期排除PLC之诊断。

Several types of ligand reactions observed under hydrothermal condition were summed up:(1) hydrolysis of pyridine nitrile, aldehyde and ester in mixed water and alcohol into pyridine-carboxylate;(2) replacement of carboxylate group with sulfonic group;(3) coupling of phenanthroline by dehydrogen;(4) oxidative coupling of methanol into oxalic acid;(5) hydroxylation of isophthalate.

总结了以往在水热条件下观察到的几类配体反应：（1）吡啶腈、醛和酯在醇和水混合溶液中水解成吡啶羧酸；（2）磺基取代羧基反应；（3）邻菲啰啉的脱氢的聚合：（4）甲醇被氧化偶合生成草酸：（5）间苯二甲酸的羟基化反应。
