      Future perspectives of Chinese medical formulae: chinmedomics as an effector.

      Traditional Chinese medicine (TCM) has been used for thousands of years to treat or prevent disease. The health care paradigm has shifted from a focus on disease to TCM therapy with a holistic approach. However, the actual value of TCM has not been fully recognized worldwide due to a lack of scientific approaches to its study. Today omics has become practically available, and resembles TCM in many aspects, and can serve as a key driving force for the translation of the traditional Chinese medical formulae (chinmediformulae) into practice, and will develop and advance the concept of the metabolomics of chinmediformulae (chinmedomics). Chinmedomics seeks to elucidate the therapeutic and synergistic properties and metabolism of chinmediformulae and the involved metabolic pathways using modern analytical techniques. It is an integral part of top-down systems biology, which aims to improve understanding of chinmediformulae. This approach of combining chinmedomics with chinmediformulae with modern health care systems may lead to a revolution in TCM therapy. Although the scientific study of chinmedomics is at an early stage and requires further scrutiny and validation, the approach has major implications to improve the efficacy of chinmediformulae. This article introduces and reviews the concept of chinmedomics, and highlights recent examples of the approach, which are presented for description and discussion.

        Shosaiko-to and other Kampo (Japanese herbal) medicines: a review of their immunomodulatory activities.

        The use of alternative medicine, including consumption of herbal products and dietary supplements, has been increasing substantially both in the United States and in Western Europe. One area that is garnering increased attention is the use of Oriental Medicine including Kampo, or Japanese herbal medicine. Herein, we review representative examples of research available on the most common use of Kampo medicinals, namely to improve the immune response. We also provide an extensive background on the history of Kampo. There are more than 210 different Kampo formulae used in Japan and most uses of Kampo are to modulate the immune response, i.e. to improve immunity. We have extracted data on seven common Kampo medicinals, and the data are reviewed with respect to in vitro and in vivo activities for both humans and experimental animals; the ingredients as well as the problems with classification of these materials are presented. Research suggests that Kampo herbals are biologically active and may have therapeutic potential. While it is believed that Kampo medicines have few side effects, there is a paucity of data on their toxicity as well as a relative lack of knowledge of the bioactive constituents and potential drug interactions of these agents.

          Diagnostic fragment-ion-based extension strategy for rapid screening and identification of serial components of homologous families contained in traditional Chinese medicine prescription using high-resolution LC-ESI- IT-TOF/MS: Shengmai injection as an example.

          The paper presents a modified and universally applicable diagnostic fragment-ion-based extension strategy (DFIBES) to efficiently process the information acquired by liquid chromatography-electrospray ionization source in combination with hybrid ion trap and high-resolution time-of-flight mass spectrometry [LC-(ESI)-IT-TOF/MS], facilitating the structural determination of serial components contained in traditional Chinese medicine prescription (TCMP). The key advantage of DFIBES is that it facilitates the rapid classification of the complicated peaks into well-known chemical families, which significantly simplifies the complicated procedures of structural characterization. Moreover, considering that a certain family of compounds usually produces identical fragment ions, the DFIBES would be widely applicable to many other families of compounds identification besides the presently validated ginsenosides and lignans. Shengmai injection, composed of Panax ginseng, Radix ophiopogonis, and Schisandra chinensis, was taken as a TCMP example to conduct and validate the proposed DFIBES. Diagnostic fragment ions (DFI) for each chemical family contained in Shengmai injection was firstly determined or proposed from the separated analysis of 15 authentic standards and the extract of S. chinensis. The ESI-MSn fragmentation patterns of ginsenosides and lignans were then systematically studied for developing the 'structure extension' approach. Upon LC-IT-TOF/MS analysis and DFIBES, more than 30 ginsenosides and 20 lignans have been rapidly detected and identified from Shengmai injection, supporting that the DFIBES is a very powerful strategy and would be widely applicable for the complicated components identification from TCMP and other complicated mixtures.
