OBJECTIVE To clarify the weight index and optimize the technology of compound Mingmu Yijing pills. METHODS Water content, dissolution time limit and bolus-forming pass rate were included as evaluation indexes. The analytic hierarchy process(AHP) and the criterion importance through inter-criteria correlation(CRITIC) method based on the objectivity of indicators were adopted, AHP-CRITIC mixed weighting method. In this way, the relative coefficients of each index were calculated for weight distribution and comprehensive score, and the molding process was optimized and verified by Box-Behnken response surface test. RESULTS Compared with the single weighting method, the AHP-CRITIC mixed weighting method was more reasonable and stable. This method finally optimized the forming process conditions of Mingmu Yijing pills as follows: adding water amount of 0.8 times, the damp mass infiltration for 0.5 h, drying temperature of 60 ℃, drying time of 8 h. The mean comprehensive score of validation experiment was 88.21, RSD was 0.29%. CONCLUSION AHP-CRITIC method scientifically determines the weight of multiple indicators, and the verification test confirms that the optimized molding process is stable and feasible, which can be used in practical large-scale production.

High altitude polycythemia (HAPC) had become one of the main common chronic diseases, which had seriously threatened the health of Plateau people. In the Tibetan medicine classic bookSi-Bu Yi-Dian, there were recordings on HAPC treatment methods and medications, which had the unique advantages of identified therapeutic effect with little side effect. This article analyzed Tibetan medicine in the prevention and treatment of HAPC from aspects such as etiology and pathogenesis, clinical treatment advantages and modern innovation study. Questions were also raised on lacking of standardization on HAPC clinical effectiveness, as well as Tibetan medicine compound material basis and action mechanisms were unclear. It was proposed that based on the inheritance of Tibetan medicine theoretical basis and clinical therapeutic effect, the Tibetan medicine original thinking should be combined with modern science and technology, in order to strengthen the analysis of ancient literature collection in HAPC treatment and data mining in medication experiences. The clinical treatment standards and medication plan should be standardized. Methods of systems biology, such as metabolomics, can be used in the further study of the scientific connotation of HAPC treatment by Tibetan medicine.

This article was aimed to survey the use of Chinese minority medicine, in order to provide differences and similarities among different Chinese minority medicine, and to analyze the relations among species resources, using range, functions and indications. It provided a basic scientific platform for the development, research and use of minority medicine. The books and journals published since the late 1970s (the country after the reform and opening up) had been collected, classified. And reference books on current Chinese minority medicine had been compiled. The results showed that the first draft of the book had been completed and delivered to the press. The dictionary had cited 53 traditional medicine used by minority groups. The total number of minority medicine was 7 734. The total characters amount in the book was 1 700 000 words. It was concluded that the species of minority medicine were various. There was rich information on their harvest, medicinal parts, functions and indications with prominent features. The existing major problems were to clarify the standard of the species as well as their major functions and indications.

Chinese medicine and Tibetan medicine both belong to the traditional medicine, and have their unique background and theoretical systems. There are similar features and differences in diagnosis of disease, syndrome and treatment between Chinese medicine and Tibetan medicine. Tibetan Zhenbu disease is common and frequently-occurring in plateau area with high morbidity, which is corresponding to rheumatoid arthritis in modern medicine and the category of Bi syndrome in Chinese medicine. During a long period of clinical efficacy verification, Tibetan treatment of Zhenbu disease presents to be little side effects, good curative effect, safe and economic etc. In the review, according to the introduction of Tibetan medicine and Chinese medicine, Zhenbu disease of Tibetan medicine and Chinese Bi syndrome will be compared in their pathogeneses and treatments to understand advantages and peculiarities of Tibetan medicine. The development of Tibentan medicine in the future will also be pointed out.

Ethnic medicine is an important component of traditional Chinese medicine and excellent traditional culture. New products of ethnic medicine are important application form to play therapeutic advantages of ethnic medicine, whose research and development should focus on the maintenance of characteristics of ethnic medicine. From the perspective of the research and development of ethnic medicine, this article discussed research ideas in the development of new products of ethnic medicine and put forward that attention should be paid to the experience on using the ethnic medicine, related literature studies, and ethnic medicine resource protection and utilization as well. In addition, this article put forward the research tactics in new products of ethnic medicine, such as medicinal materials, effective parts, active ingredients, the secondary development research and so on, with a purpose of improving the level of researching and developing new products of ethnic medicine.
