ABSTRACT
Ginseng is a plant in the family Araliaceae and the genus Panax with the formal name of Panax ginseng C. A. Meyer and the treasure of traditional herbal medicine resources as the "king of herbs". Ginseng has been traditionally used for over 2,000 years in Asian countries, especially in China and Republic of Korea. During the ginseng industry chain, the cultivation in farmland and seed breeding are important for sustainable development of ginseng resources. Active components in ginseng including ginsenosides, polysaccharides, phenolic compound and their therapeutic benefits for multiple diseases are being studied. This paper aimed to review current research status and problem-solving strategies for each step of ginseng industry, including ginseng growing cultivation and seed resources, basic and clinical studies as well as comparison of ginseng industry between China and Republic of Korea, hoping to provide a reference for research direction and future development of ginseng industry.
ABSTRACT
Objective To analyze the distribution of main pathogens,antimicrobial susceptibility,and clinical characteristics of osteoarticular infection,and provide evidence for clinical treatment.Methods A retrospective sur-vey was conducted on clinical data and pathogenic results of hospitalized patients with osteoarticular infection diag-nosed by etiology and pathology in Peking University First Hospital from 2009 to 2016,surveyed data were analyzed statistically.Results A total of 99 cases of bacterial osteoarticular infection were enrolled,100 strains of pathogenic bacteria were isolated,gram-positive bacteria accounted for 67.00%,49.00% of which were Staphylococcus spp., Enterobacteriaceae bacteria accounted for 67.74% of 31 strains of gram-negative bacteria.Isolation rate of methicil-lin-resistant Staphylococcus aureus (MRSA)was 16.13%,resistance rates of Staphylococcus spp.to fluoroquino-lones and rifampicin were both lower than 30%.Complication with other site infection (urinary tract infection,in-testinal infection,bloodstream infection)was an independent risk factor for gram-negative bacterial steoarticular in-fection (P＝0.027,OR＝10.536,95% CI:1.300－85.417).Conclusion Staphylococcus spp.is still the main pathogen causing osteoarticular infection,proportion of MRSA is low.Patients with urinary tract infection and in-testinal infection as well as long duration of implant should be considered the possibility of gram-negative bacterial infection when they develop steoarticular infection.
ABSTRACT
Protein kinase C beta (PKCbeta) is a multifunctional serine/threonine protein kinase, which plays an important role in many cell signaling pathways. PKCbeta takes part in multiple physiological processes, including regulation of the cell cycle, differentiation, proliferation, apoptosis and angiogenesis. Increased PKCbeta activity has been observed in many human cancers, such as colon, breast and haematological malignancies. At present, Enzastaurin is mostly studied in preclinical and clinical studies, which is a selective PKCbeta inhibitor. This review focuses on the functional properties of PKCbeta, its role played in tumors and Enzastaurin.
