Methods The global cerebral ischemia/reperfusion injury model was established by the four-vessel occlusion (4VO) method, and then the model animals sere given high-middle-and low-dose muscone. Meanwhile, sham-operation group, model group, and positive control group were also set up. The rats neuroethology behavior, and the contents of superoxide dismutase, malondialdehyde and excitatory amino acid in is-chemic brain tissue were examined.

Methods Estradiol-randomly methylated β-cyclodextrin (E2-RAMEB) solution, and 70% ethanol solution of estradiol and estradiol nasal spray in 3 different doses 0.16、0.48、1.60 mgkg^(-1 were nasally administrated to rats, respectively. Non-compartment statistical moment method was used in pharmacokinetics study.

In order to study the factors related to Enterobius infection among per-schoolchildren, a structural questionnaire with multi-stages and a random sampling was designed to interview parents of 702 pre-schoolchildren. The questionnaire included personal information of the children: their educational background and parents' occupation; the status of their housing; their handwashing habits, and their frequency and habits of bathing, etc. In addition, the children's pinworm infections were examined using two-consecutive-day adhesive cellophance paper perianal swabs. Variables causing the pinworm infection among infected and noninfected children were analyzed by x2-test and multi-variable tests including discriminant analysis and stepwise multiple regression.

为了解学龄前儿童蛲虫感染之因素，以结构型问卷多步骤随机抽样访视702名学龄前儿童的家长，问卷的内容包括：儿童个人资料、儿童父母亲教育程度、职业、住屋情形、卧室分配情形、手部卫生习惯、洗澡习惯等，并以连续两天玻璃胶纸肛围擦拭法〈two-consecutive-day adhesive cellophane paper perianal swabs〉检查儿童的蛲虫感染情形，儿童蛲虫感染与各单变项的相关，以卡方检定〈x2-test〉分析，而多变项的分析则以判定分析〈discriminant analysis〉及逐步复回归〈stepwise multiple regression〉进行分析。

Methods Volunteers of medical staff responsible for respiratory infection from 7 hospitals in Hubei province were enrolled. A self-report standard questionnaire was used to assess the general state of well-being and the frequency of airway infection during recent two years. Sera from the medical staffs and from the age-matched healthy subjects of nonmedical occupation were tested by ELISA for SCPIgG.

Based on chapter two, In chapter three, the method of multiple scales is introduced to the study of the multiple-dimensional nonlinear stochastic systems under random external excitation. Using method of multiple scales, we strictly deduce the equation of modulation of amplitude and phase. The effects of random excitations are analyzed; numerical simulations verify the results. Theoretical and numerical simulations show that when the intensity of the random excitation increases, the nontrivial steady state solution may be changed from a limit cycle to a diffused limit cycle.

在第二章基础上，第三章将多尺度法引入到相应的随机系统的研究中；严格推导了系统的约简方程，用矩方法求出稳态解应满足的方程，获得一些结果；并且数值模拟结果与理论推导的结果是一致的；并注意到，与其对应的确定性系统相比较，系统响应从周期解变为近似周期解，系统的相轨线从极限环变为扩大的近似极限环；随着激励带宽的增大，此扩大的近似极限环的宽度将增大。
