Content-based medical image retrieval has become a hot research topic due to the rapid increase of image database. In this paper, we present a method of medical images retrieval, based on texture analysis with Haar wavelet transform. Meanwhile, its effectiveness is compared with the method of retrieval based on co-occurrence matrix. A prototype system is implemented and the experiments show that the method has a much better effect.

Based on chest images' features, this paper presents a retrieval method with domination color of partition, gray level co-occurrence matrix and gradient image shape invariant moments, as well as the fusion of them and the technique of relevance feedback. In Windows Vista environment with Visual C + +, a chest image retrieval prototype is implemented and the experiments have proved that this method has a better retrieval effect.

Mongolian folk medicine, the important part of Mongolian medicine, is the main means, method and weapon of disease prevention, treatment and health care. Mongolian materia medicas are the important literatures of guiding the healthy development of the modern Mongolian medicine with a long and dazzling history. Since the founding of new China, a new history chapter of Mongolian folk medicine was opened under the attention and support from all levels of party and government. This paper intends to provide comprehensive insight into the rapid development of Mongolian folk medicine. The resources, phytochemistry, quality standard, pharmacology, dosage forms reform and production were reviewed to expound the process that Mongolian folk medicine was developed from traditional practices to scientific development
