Objective To identify the common Tibetan herb Dong-Na Duan-Chi by molecular pharmacognosy. Methods Ethnopharmacology investigation was carried out and local herbalists were visited to observe which plants were being used as Dong-Na Duan-Chi. Then, nuclear ribosomal DNA ITS sequences were amplified and sequenced for molecular identification. Results The botanic origins of Dong-Na Duan-Chi in Tibet Autonomous Region were authenticated as two species, i.e. Veronica eriogyne H.Winkl. and Veronica ciliata Fisch.. The sequences of ITS for Veronica eriogyne and Veronica ciliata are 551 bp and 552 bp in size. The results showed that nrDNA ITS sequences could be used to discriminate V.eriogyne and V.ciliata from closely related species. Conclusion nrDNA ITS sequences can be used as the molecular markers to identify the Tibetan herb Dong-Na Duan-Chi from other species of the same genus Veronica L.

The grass-root level health workers play a decisive role in health services, the researches on human re-sources in primary healthcare, therefore, in many countries of the world have been widely concerned. This article re-flected on 20 research papers related to recent aspects of primary healthcare human resources; described the amount, quality, structure and distribution of workforce for health; analyzed the factors of health workforce development in eco-nomic, social, policy and other aspects and elaborated the strategy to develop primary health professionals, namely through strengthen the training of talent personnel in rural areas, adjust the professional structure of medical education, and implementation of preferential policies to attract and stabilize the health personnel.
