当前部队医院正处于发展转型期，如何引导科技干部适应转型发展新形势，经受住各种考验，始终保持理性平和、协调平衡、积极向上的心理状态，是一个不容忽视的现实问题，也是事关医院内部和谐和医院建设发展又好又快的大事，更是我们思想政治工作者必须着力认真研究、加以解决的重要课题。     

Reproductive health knowledge and implications: A study in Nigeria

Forty-five percent of Nigeria's population is under age 15. This study employed a questionnaire to learn the level of reproductive health knowledge of 416 male and female Nigerian students ages 10 through 16.

The Chi-square statistical procedure was used as demographic characteristics were related to reproductive health knowledge among the pre-teen and teenage youth. Statistically significant (p #lt 0.05) relationships were found between variables such as knowledge of reproduction, family planning, and AIDS when each was compared separately to age, gender, living situation while at school, school club memberships, and so on. With respect to reproduction and related topics, older teenagers indicated more knowledge than pre-teenagers, girls more than boys, and those living in dormitories more than those living at home or in other housing while attending school.

Television ranked first in terms of students' sources of information on reproduction, pregnancy, birth control, and AIDS. Newspapers ranked second, radio third, teachers fourth, and parents fifth. Perhaps the most striking data are the “I don't know” responses with respect to AIDS. Thirteen percent had not heard of AIDS, 27 percent did not know how AIDS is transmitted, 29 percent did not know the seriousness of AIDS, 37 percent did not know how to avoid AIDS, and 14 percent did not know that a mother with AIDS might infect her baby. Recommendations are made for increasing health services and education concerning reproductive health for pre-teen and teenage students.     

广东省结核病流行菌株研究

目的：从分子流行病学的角度探讨广东省结核分支杆菌菌株流行的分布。方法：构建广东省74株临床分离的以RFLP为基础的结核分支杆菌的IS6110 DNA指纹图谱技术，确诊结核分支杆菌菌株的流行分布。结果：24．3％（18／74）的结核菌株的IS6110 DNA指纹相似值在1－0．65之间，鉴定结果为它们均是“北京家族”结核分支杆菌菌株。结论：广东省结核菌株流行主要存在着遗传关系接近，在基因水平上相关程度较高的“北京家族”结核分支杆菌菌株，且该家族菌株正以一定的比例在我省流行。     

以临床技术流程功能定位需求为基础的生理监测仪功能配置

Evaluation of stroke rehabilitation by randomized controlled studies: a review

In all, 22 reports of 20 randomized, controlled rehabilitation studies were evaluated. In 18 of these, the design of the trial was parallel, with a cross-over format being employed in the remaining 2 instances. Seven studies related to intensive rehabilitation during the early post-acute period. In six others, specific techniques--sometimes associated with traditional physiotherapy procedures--were compared: biofeedback, perceptual retraining, and amphetamine treatment. Eight experiments evaluated speech therapy in aphasia. Frequently, methodological considerations limited the interpretation of the results. The review showed that: 1) as regards activities of daily life and motor function, differences as between rehabilitation in stroke units on the one hand and non-rehabilitation or rehabilitation in medical wards on the other, were detected in relatively few quality studies and remained particularly inconclusive insofar as life in the home environment was concerned; 2) rehabilitation for aphasia and perceptual dysfunction proved effective for at least several months after acute stroke; 3) in general, examination of the reports cited revealed no differences in the effects of biofeedback and perceptual retraining vs conventional physiotherapy; 4) rehabilitation, whether administered by specialists or amateur caregivers purpose-trained by specialists, proved equally effective for aphasia. These conclusions constitute a valuable basis for the development and evaluation of modern rehabilitation programs for stroke patients.

A case-control study of breast cancer among Japanese women: with special reference to family history and reproductive and dietary factors

Summary To study the effects of family history and reproductive, anthropometric, and dietary factors on the risk of breast cancer among low risk populations, we conducted a hospital-based case-control study involving 908 patients with breast cancer and their matched controls, in Japan. A positive family history of breast cancer significantly increased the risk of breast cancer (odds ratio = 1.52, 95% confidence interval: 1.14–2.03). The risk further increased with increasing number of family members affected. Obesity, single marital status, fewer births, a late childbirth, and less consumption of green-yellow vegetables and dairy products were also associated with an increased risk of breast cancer. These associations were independent in multivariate analyses. There was no increase in risk associated with consumption of high fat foods. When analyzed by menopausal status, the association with family history of breast cancer, especially in the first degree of relatives, was more evident for premenopausal breast cancer. The associations with obesity and lower consumption of dairy products were more pronounced for postmenopausal breast cancer, while those with lower parity and single marital status were stronger for premenopausal breast cancer.
