Results Critical stenosis or occlusion of contralateral arteries were found in the siphonic part of internal carotid artery in 6 patients, terminal ICA or proximal middle cerebral artery in 6 patients, and distal MCA in 1 patient. Seven patients had proximal ICA occlusion. The brain MRI showed typical watershed cerebral infarctions in 8 patients.

结果 所有患者均存在对侧颅内外血管严重狭窄或闭塞，其责任血管分布：颈内动脉虹吸段6例；颈内动脉末端或大脑中动脉起始部6例；大脑中动脉的M2段1例；颈内动脉起始部7例。8例头颅磁共振显示典型的分水岭脑梗死。6例行血管重建治疗，临床未再发作。

Methods: The expression of apoptosis and the positive expression of p53, bcl－ 2 proteins were observed in 31 cases of breast cancer in situs, 20 breast dysplasia and 20 breast hyperplasia by using DNA nick end labeling technique and immunohistochemical staining . Eight normal breast tissues were used as control.

利用DNA缺口末端标记技术和免疫组织化学染色，原位观察31例乳腺癌，20例乳腺不典型增生和20例乳腺单纯性增生中细胞凋亡和p53、bcl－2蛋白的表达，以 8例正常乳腺组织作为对照。

The key steps involved Friedel-Crafts reaction of o-cresol and the Wittig reaction for construction the skeleton of amine moiety,at the same time, using the synthesis of E,(7S)-7-methoxytetradec-4-enoic acid in chapter 2,and Johnson-Clainsen rearrangement as a key step for construction the fatty acid part,the corresponding acid was prepared in 23%and 50%overall yield,respectively.

随后将手性不饱和脂肪酸和氨片段进行酰胺化反应构筑了malyngamide M的基本骨架，再将Z-烯氯转化为E-烯氯完成了目标分子的全合成，高立体选择性地构筑了末端烯氯结构，为制备其它含有类似烯氯结构的malyngamides探索出行之有效的合成路线。

The Chitinase of Saccharomyces cerevisiae(CTS1-2) is an Endochitinase which is endogenous in Saccharomyces cerevisiae. Its recognition and slipt site lies in the β-1,4 glucosidic linkage of homopolymer. Included in the amino acid sequence from N-terminal to C-terminal of the Saccharomyces cerevisiae chitinase are signal peptide sequence, catalytic domain, binding domain and a C-terminal shorten region.

酿酒酵母几丁质酶(Chitinase，CTS1-2)是一种来自酿酒酵母的内切几丁质酶，它的酶切位点位于其同聚物内的β-1，4连接的糖苷键，酶蛋白分子结构从N端到C端依次为信号肽、几丁质催化区、几丁质结合区以及一个短的C末端区。

To all project practicality, the introduction is given to the operational characteristics, the methods for calculation and the researching actuality of the tail tunnels with sloping ceiling underground hydropower stations the Three Gorges. This paper has discussed in detail the characteristic method being the same with the compressive flow and the Priessmann solution being the same with the free-surface-pressure flow. And how to deal with boundary conditions has been expatiated. Also hydraulic transient process of tremendous load fluctuation in the tail tunnels with sloping ceiling has been numerical simulated and the Fortran program for numerical simulation has been given. The paper gain the maximal press for tail end of the shell, the maximal rising rate of rotational speed of generating set, the maximal vacuum degree for inlet of the tail tunnels and so on under 11 kinds conditions of tremendous load fluctuation. These conditions include the design conditions, the check conditions and the superposition conditions. Finally, the computing results have been analyzed and summarized. The end chapter is the general comment of the whole-length content and the describing of the intending view of researching.
