In this paper, the domestic varieties and quality standard of Leguminosae medicinal plants used in Tibetan medicine were analyzed. The results showed that there were 36 genera and 142 species (including varieties), as well as 64 medicinal materials varieties of Leguminosae plants were recorded in relevant literatures. In relevant Tibetan standards and literatures, there are great differences in varieties, sources, used parts, and efficacy of medicinal plants. Among them, about 38.0% (including 54 species) of the endemic plants, about 25.4% (including 36 species) of the original plants have medicinal standard legal records, except 9 kinds of traditional Chinese medicine general quality standard more fairly completed, the most varieties have only description about characters, identification, etc. Therefore it is necessary to reinforce study for the herbal textual, resources and the use present situation, chemical components and biological activity, quality standard, medicinal terms specification, to promote establishment of quality standard system for variety-terminologies-sources of Tibetan medicinal plants.

Quantity is the key factor to ensure the safety and effectiveness of medicines. It is very important to study and determine the traditional measuring units and their quantity values of Tibetan medicine. Based on the literature records of Tibetan medicine and combined with modern experimental verification and investigation research, this study determined the reference, name, and conversion rate of traditional measuring units of Tibetan medicine. Meanwhile, through large sample sampling and repeated quantification of refe-rence of basic units, its weight and volume were clarified. The modern SI volume and weight unit values corresponding to the traditional volume and weight units of Tibetan medicine were deduced, and the correctness, reliability, and practicability of these determination results were demonstrated. This study also put forward some specific suggestions and reference values for formulating the standards of measuring units of weight and volume of Tibetan medicine. It is of great significance in guiding the processing, production, and clinical treatment of Tibetan medicine, and promoting the standardization and standardized development of Tibetan medicine.

Due to the profound theoretical rationale, perfect diagnosis and treatment system, and characteristic medicinal resources, Tibetan medicine has been passed down to the present day as one of the four traditional medicine systems all over the world. With the development of modern society and the change in people's concept of seeking medical services, Tibetan medicine has gradually attracted wide attention by virtue of its natural, green and safe diagnosis and treatment characteristics, which enables it to be vigo-rously developed and inherited. There are numerous ancient books on Tibetan medicine, covering a large number of ancient prescriptions, which has laid a solid foundation for later scholars to thoroughly investigate the diagnosis and treatment rules in Tibetan medicine and apply them to modern clinical practice. Screening the classic prescriptions that meet modern clinical needs from those numerous ancient books is a new direction in the inheritance and development of Tibetan medicine. On the basis of historical origin and current application status of ancient prescriptions in Tibetan medicine, this paper preliminarily elaborated the definition of classic prescriptions of Tibetan medicine and their general screening principles and precautions, and also discussed the modern inheritance paths of classic prescriptions in Tibetan medicine from basic research, post-marketing evaluation, and the development of novel preparations. Considering the shortcomings in the present study, the key technical issues mentioned need to be more deeply explored and analyzed in future studies.

By tracing to the origin of Tibetan medicine, it is known that Tibetan medicine absorbs a variety of medical ideas such as traditional Chinese medicine, Vedic medicine, Persian medicine and Byzantine medicine, and forms a unique theoretical system. The meridian-acupoint system and the characteristics and application of external therapies such as bloodletting and moxibustion in Tibetan medicine are analyzed by elaborating the relevant aspects of acupuncture and moxibustion involved in treatment of diseases listed in Medical Canon in Four Sections. The paper emphasizes the introduction of ironing moxibustion and huo'er moxibustion of fire moxibustion and the application of separation-action decoction and ghee therapy in bloodletting, as well as alternative therapy. Besides, by taking the external treatment of cirrhotic ascites and head trauma as an example, the idea of acupuncture and moxibustion therapy in Tibetan medicine embodied in the Medical Canon in Four Sections is explained so as to benefit the development of acupuncture and moxibustion therapy in Tibetan medicine.

The 1H-NMR fingerprints of three different species tibetan medicine sea buckthorn were established by 1H-HMR metabolomics to find out different motablism which could provide a new method for the quality evaluation of sea buckthorn. The obtained free induction decay (FID) signal will be imported into MestReNova software and into divide segments. The data will be normalized and processed by principal component analysis and.partial least squares discriminant analysis to perform pattern recognition. The results showed that 25 metabolites belonging to different chemical types were detected from sea buckthorn,including flavonoids, triterpenoids, amino acids, carbohydrates, fatty acids, etc. PCA and PLS-DA analysis showed three different varietiest of sea buckthorn that can be clearly separated by the content of L-quebrachitol, malic acid and some unidentified sugars, which can be used as the differences metabolites of three species of sea buckthorn. 1H-NMR-based metabonomies method had a holistic characteristic with sample preparation and handling. The results of this study can offer an important reference for the species identification and quality control of sea buckthorn.

The CO I gene sequences of Qianghuoyu, Pachytriton labiatus and Gehyra mutilata were achieved by PCR amplification and bi-directional sequencing. Furthermore, a pair of specific primers SJYW1 and SJYW2 in the non-conservative district were designed through sequence alignment. The PCR reaction condition was established by changing the annealing temperature and cycle numbers. The results showed that 350 bp DNA fragment was amplified from Qianghuoyu in PCR with annealed temperature at 54 °C and the cycle number was 25 cycles, whereas not any DNA fragment was amplified from P. labiatus and G. mutilata under the same reaction condition. This method is well-performed in the identification of Qianghuoyu for its excellent specificity and repeatability.
