研究了肿瘤热疗中实施组织温度场预示、优化加热及功率调节一体化的问题。基于新近建立的生物传热热波方程，采用双倒易边界元方法，对在一定加热方式下生物组织内的热量传递规律进行了考察。对传统Ｐｅｎｎｅｓ方程和生物传热热波方程的对比研究发现，在针对真实热疗过程中由于调节加热功率而导致的温度场演化进行模拟时，两类方程的预示结果存在明显差别，这提示了在预测和控制生物体内微小温度时所采用的精细模型应是理论基础更为严密的生物传热热波方程，且在瞬变加热作用下尤为关键。文章还研究了血液灌注率在组织温度场发生改变中的作用及其生理学意义。这些研究为建立实用的肿瘤热疗仪器打下了一定的基础。

The non-integral dimensions ultrasonic phased arrays and their scanning and testing methods in a borehole are studied. First, the focusing acoustic fields excited by the 1.2.D, 1.5D, and 1.75D phased arrays are analyzed, and then the imaging resolution in the elevation direction and the influence of the dynamic elements are investigated. Second, the focusing and deflexion characteristics of the acoustic fields excited by the annular and segmented annular phased arrays are studied, and they are compared with those excited by the 2. surface array. The application method of the 1.2.D, 1.5D, and 1.75D, annular and segmented annular phased arrays in acoustic logging are analyzed and discussed. It provides a theoretical foundation for the application of the ultrasonic phased arrays in acoustic logging.

Objective:Ophthalmologists, patients, and its family can select intraocular lenses, if they can observe the images constructed by intraocular lenses (IOL) before operation. Methods: According to this request, the eye model that consists of a photographic lens with 3.mm focal length, an IOL put in a water cell and a charge coupled device (CCD) camera is constructed. The images constructed by the lenses are observed on a monitor of personal computer and the contrast of the images are analyzed by using a commercial image processing software. Results: The MTF of the eye model is analyzed and it is found that the MTF resembles the total MTF of human eyes including the response of retina to brain. And also, we are able to observe the images constructed by changing the diameter of a pupil and by putting glasses in front of the camera lens. The observed images and analyzed results using some intraocular lenses, a resolution chart and a contrast chart are shown here. Conclusion: The proposed eye model is useful for many cases especially for the informed consent. [FK(WB80011。5]

Ecological balanced fertilization what we have proposed based on the general fertilization model, optimum technology and ecological fertilizer. The system of ecological balanced fertilization include: service object, aim of fertilization, theory basis, technology system, fertilizer using, and service system. Original innovations of the general model are as follow:(1) the interrelation of crop, soil, fertilizer and environment were considered ecologically;(2. the parameters of the model were derived from raw data( laboratory data, empirical data or survey data);(3. raw data was easy to acquire;(4) parameters could be connected by model quantificationally;(5) method of acquiring model parameters was provided;(6) relative simpleness, convenience and stabilization were what the model possesses, and yield improving and soil fertility, environment protection could be achieved after fertilizing by this model. The specialist system we proposed based on general fertilization model, regional fertilization model and block fertilization model. After ten years study, experiment and popularization, now, there are a series of softwares include network version, uniprocessor version, touch screen fertilization machinery and PDA fertilization machinery, and they have been popularized above 2. provinces .

To determine whether there is sudden contaminant in the closed-cabin,we can judge on a basis that whether the corresponding concentration of contaminants in the cabin higher than a certain threshold ***,as noise impact of contaminants measurement instruments,it is difficult to determine accuratelywhether the sudden change of concentration is due to strong noise of monitoring instruments or caused by a sudden contaminant source,which results in the delay and inaccuracy of contaminant source identification and concentration *** order to solve this problem,a new method to detect sudden contaminant based on χ2.distribution is presented in this *** detection method could overcome the impact of sensor noise,and get the information of sudden contaminant starting time accurately,which could ensure the reliability of the contaminant concentration prediction and hazard *** results show the effectiveness of the algorithm.

World Journal of Gastroenterology 2002年第2期8卷 213-216页

作者： Yong Li You-Yong Lu,beijing Institute for Cancer Research,beijing Laboratory of Molecular Oncology,{2. of Oncology,Peking University,beijing 10003.,china beijing Institute for Cancer Research Beijing Laboratory of Molecular Oncology School of Oncology Peking University 1 Da-Hong-Luo-Chang Street Western District Beijing 100034 China.

AIM: To develop and optimize cDNA representational difference analysis (cDNA RDA) method and to identify and clone garlic up-regulated genes in human gastric cancer (HGC) cells. METHODS: We performed cDNA RDA method by using abundant double-stranded cDNA messages provided by two self-constructed cDNA libraries (Allitridi-treated and paternal HGC cell line BGC82. cells cDNA libraries respectively). Bam H I and Xho I restriction sites harbored in the library vector were used to select representations. Northern and Slot blots analyses were employed to identify the obtained difference products. RESULTS: Fragments released from the cDNA library vector after restriction endonuclease digestion acted as good marker indicating the appropriate digestion degree for library DNA. Two novel expressed sequence tags (ESTs) and a recombinant gene were obtained. Slot blots result showed a 8-fold increase of glia-derived nexin/protease nexin 1 (GDN/PN1) gene expression level and 4-fold increase of hepatitis B virus x-interacting protein (XIP) mRNA level in BGC82. cells after Allitridi treatment for 72.. CONCLUSION: Elevated levels of GDN/PN1 and XIP mRNAs induced by Allitridi provide valuable molecular evidence for elucidating the garlic's efficacies against neurodegenerative and inflammatory diseases. Isolation of a recombinant gene and two novel ESTs further show cDNA RDA based on cDNA libraries to be a powerful method with high specificity and reproducibility in cloning differentially expressed genes.
