本论文研究了目前未见国内外文献报道的、水杨醛中苯环上含有取代基的水杨醛缩脱氢枞胺Schiff碱及其金属配合物的合成与表征，共计获得了21个新的化合物，从而为后期生物活性的测定及不对称催化提供研究基础和实验样品。

In this thesis, two synthetic routes for the incorporation of sugar moiety into C5(5") or C3(3") of salicylaldehyde part of Salen Mn complex were designed and several corresponding compounds were prepared, as carbohydrate derivatives are widely used in asymmetric catalytic reactions.

鉴于糖类衍生物在不对称催化反应中的广泛应用，设计了两条分别在Salen Mn配合物水杨醛部分C5(5′)、C3(3′)位并入糖基的路线并合成了相应的化合物。

The binding interaction of DNA with the di-iron complex 〓, designed as a model for the di-iron active site in mammalian purple acid phosphatase , are examined firstly and spectroscopically.

对所有研究的含有双核铁、双核锌及双核铜的配合物促进DNA双链水解断裂的反应性进行比较，我们发现要有效地水解断裂DNA双链，对DNA骨架的磷酸基氧原子有一定配位作用的双核金属离子是必要的，因为两个金属离子间存在协同作用，这与有关的天然酶类似。

笔者于临床上用甲硝唑（又名灭滴灵、甲硝哒唑、甲硝基羟乙唑）内服配合局部用20%硝酸银溶液点灼，治疗阿弗他性口炎128例进行跟踪观察，收到较理想的效果，而临床上未见有资料报道。

To determine whether a similar outcome would prevail in patients with supraspinatus tendinopathy, the investigators randomly assigned 53 subjects (57 shoulders) to rehabilitation combined with use of a transdermal nitric oxide patch (1.25 mg glyceryl trinitrate/24 hours), or rehabilitation alone.

为了确认这项治疗法是否对岗上肌肌腱炎患者具有同样的效果，研究人员随机召募了53位患者(57个肩部病变)，分为两组；一组给予复健治疗，并配合经皮吸收的一氧化氮贴片(1.25 mg 硝基甘油/24小时)；另一组为单纯的肌腱复健治疗。

The influence of binding of cisplatin adducts on tautomeric equilibrium of guanine was investigated using quantum chemical method. The monoaqua adduct [Pt(NH3)2Cl(H2O)]＋and the diaqua adduct [Pt(NH3)2(H2O)2]2＋were chosen for coordination to the N(7) site of guanine tautomers.

使用量子化学MPW1PW方法，优化了顺铂键连到DNA碱基-鸟嘌呤及互变异构体N7形成的配合物的构型，同时用MP2方法计算其能量，以研究顺铂对鸟嘌呤互变异构作用的影响。
