Results: The major findings are:(1) the public held strong belief in the preventability of AIDS/STDs and considered prevention was of greater importance than biomedical interventions,(2) of the possible prevention strategies proposed by the research participants, personal behavior control was deemed as the most ef fective; meanwhile a sense of powerlessness was expressed while mentioning the government's responsibility for keeping the quality of blood supply and managing the potential dangers posed by other people's behavior,(3) condoms were well accepted as an effective tool for AIDS/STDs prevention but were used mostly for the purposes of contraception than HIV/STDs prevention, and (4) people were unwilling to use condom mainly due to sensational and psychological discomforts.

结果：(1)民众多认为爱滋病的「可预防性」极高，且视预防比高科技的解决方式重要；(2)个人行为的控制乃最受民众重视的防治途径；但对政府的血液安全管制及他人行为所可能造成的危害较感无力；(3)民众对保险套之使用持相当肯定之态度，不过曾使用者绝大多数以避孕而非以预防性病为主要目的，男女性在这方面的行为差异极大；(4)身体及心理上的不适与不悦被一般民众指出是保险套使用率低的主要原因，(5)教育程度对民众在预防的认知及信念扮演极重要的角色。

In order to investigate the excitation mechanism and response characteristics of wind-rain induced vibration of stay cable,an instrumentation system of wind-rain induced vibration measurement,which consists of anemometer,rain gauge and accelerometer,was installed on the Dongting Lake Bridge,Yueyang,China.

为了研究斜拉桥拉索风雨振的机理及响应特征，在岳阳洞庭湖大桥建立了由风速仪、雨量计、加速度传感器组成的风雨振现场观测系统，观测到了多次拉索风雨振现象；得到了发生拉索风雨振时风速、风向及雨量的基本条件，分析了风雨振时拉索振动的幅值、主振频率、模态参与特性及空气动力负阻尼比等响应特征。

Methods:The levels of plasma ET,serum malondial dehyde and super-oxide dismutase were measured by the methods of nalysis of radioimmunoassay,thiobarbiturate and xanthin oxidasein the blood samples from 68 patients with APP,and 29 normal controls.

采用放射免疫分析法、硫代巴比妥酸法及黄嘌呤氧化酶法测定68例APP组、及29例正常对照组血浆ET、血清丙二醛及超氧化物歧化酶的含量。

Stenosis of internal caroid antery was found in 32 of 48 branches in 24 case. 5 branches were occlusive and 11 branches were normal. 22 cases with large or moderate cerebral infarction volume （＞5 cm3） confirmed by CT and MRI were smaller than those on MSCTPI as having abnormal perfusion lesions,which were moderate and obvious stenosis and occlusion on MSCTA. In 2 cases with small cerebral infarction volume（＜5 cm3）, MSCTPI and MSCTA revealed normal.

其中32支颈内动脉呈不同程度的狭窄，5支颈内动脉闭塞，11支血管无狭窄。22例在常规CT及MRI图像上为中及大体积梗死（＞5 cm3）的患者，MSCTPI发现与梗死灶相对应的异常灌注区，且均比常规CT及MRI图像上病灶体积大， MSCTA显示颈内动脉呈中重度狭窄或闭塞。2例未发现明显灌注异常的患者，为小体积梗死灶（＜5 cm3），MSCTA显示颈内动脉正常。
