OBJECTIVE To study the genetic relationship and diversity of 3 species which belong to Tripterygium. METHOD Samples were collected and divided into 4 types: typical T. wilfordii, typical T. hypoglaucum and their middle type according to morphological characters, and T. regelii. RAPD markers were used to measure the genetic relationship and diversity of(More)
In this paper, the production and marketing of medicinal materials of plant origin are sorted and analyzed. The total annual yield and total output value are presented. The resources sustainable development is discussed by three aspects, i.e., the yield Top 60 items, rare and endangered species and several wild drugs should be deeply concerned. Relevant(More)
A Gram-stain-positive, rod-shaped actinobacterium, designated strain I10A-01402(T), was isolated from surface-sterilized roots of a medicinal plant, Perilla frutescens, collected in a suburb of Beijing, China. Chemotaxonomically, the strain contained ll-diaminopimelic acid as the diagnostic diamino acid and MK-8(H4) as the predominant menaquinone. The(More)
An endophytic actinomycete, designated strain I10A-01259(T), was isolated from a surface-sterilized fruit of Lonicera maackii (Rupr.) Maxim., a medicinal plant, which was collected from a suburb of Beijing, China. Whole-cell hydrolysates of the isolate contained galactose and meso-diaminopimelic acid. The predominant phospholipids were phosphatidylglycerol(More)
Mitochondria play an important role in pathophysiology of inflammatory and neuropathic pain but the mechanism is unclear. So far no comprehensive study exists that evaluates the changes of mitochondrial dynamics following the pain. In this study, we detected the mitochondrial distribution and subcellular morphology by using intrathecal injection of(More)
AIM To discuss the intraspecific relationship in Magnolia officinalis and the genuineness of Cortex Magnoliae officinalis, and to find some DNA characters of certified "Houpo". METHODS Thirty-three samples from eleven locations, which can represent most of the distribution of M. officinalis, were selected. The total DNA was extracted. Severty-four random(More)
In our previous study, we demonstrated that fibroblast growth factor 2 (FGF2) administration alleviated posttraumatic stress disorder (PTSD) symptoms via an "astrocyte-related" mechanism. We further investigated the changes in the astrocytic glutamate transporters GLAST and GLT-1 and in JAK/STAT3 signaling (which is involved in astrocyte activation and(More)
Research development of germplasm resources of Salvia miltiorrhiza was reviewed in the aspects of species resource, geographic distribution and varieties, biological characters and culture varieties, and cell and tissue culture. It was suggested that more attention be paid to waters-soluble constituents when evaluating the quality of the medicine, and much(More)
Thermo- and pH-responsive semi-IPN polyampholyte hydrogels were prepared by using carboxymethylchitosan and poly(N-isopropylacrylamide) with N,N'-methylenebisacrylamide (BIS) as the crosslinking agent. The swelling characteristics of these hydrogels at distinct compositions as a function of pH and temperature were investigated. It was found that the(More)
Tissue engineering scaffolds play a vital role in regenerative medicine. It not only provides a temporary 3-dimensional support during tissue repair, but also regulates the cell behavior, such as cell adhesion, proliferation and differentiation. In this review, we summarize the development and trends of functional scaffolding biomaterials including(More)
