Integrative Analyses of Transcriptomics and Metabolomics in Immune Response of Mats to Infection.

This study utilized to infect , analyzed the effects on the transcriptome and metabolome, and further investigated the antibacterial function of . We performed transcriptome and metabolome sequencing on the infected with and its control groups, and performed a joint analysis of transcriptome and metabolome results. Upon screening, 4560 differentially expressed genes were obtained in the transcriptome and 71 differentially expressed metabolites were obtained in the metabolome.

Potential lipase inhibitors from Chinese medicinal herbs.

Context: Obesity has become a major health concern, and it places both personal and economic burdens on the world's population. Traditional Chinese medicinal herbs are rich source of lead compounds and are possible drug candidates, which may be used to treat this condition.

Objective: This study screened potent pancreatic lipase inhibitors found in traditional Chinese medicinal herbs for ability to treat obesity.

[Research on Chinese medicine pairs effects of Panax notoginseng and Bletilla striata before and after compatibility on contents of notoginsenosides].

To discuss the synergistic mechanism of compatible use of two medicinal herbs,Panax notoginseng and Bletilla striata, an HPLC was established to determine two ginseng saponins (20S)-ginseng saponin Rg₃ and ginseng saponin Rh₄ contained in single decoction of Panax notoginseng as well as in compound decoction of Panax notoginseng and Bletillastriata in different compatibility ratio (1∶0.5, 1∶1, 1∶2), followed by analyzing the impact of amount of notoginsenosides after compatibility. As a result, compared with the single decoction of Panax notoginseng, the contents of ginseng saponin Rg₃ and ginseng saponin Rh₄ in the compound decoction of Panax notoginseng and Bletillastriata were on the rise as the increasement of the amount of Bletillastriata.

[HTRF-based high-throughput PGE2 release prohibition model and application in discovering traditional Chinese medicine active ingredients].

Prostaglandin (PG) E2 is an active substance in pathological and physiological mechanisms, such as inflammation and pain. The in vitro high-throughput assay for screening the inhibitors of reducing PEG2 production is a useful method for finding out antiphlogistic and analgesic candidates. The assay was based on LPS-induced PGE2 production model using a homogeneous time-resolved fluorescence(HTRF) PGE2 testing kit combined with liquid handling automation and detection instruments.

Requirements of calcium fluxes and ERK kinase activation for glucose- and interleukin-1beta-induced beta-cell apoptosis.

Increasing evidence indicates that beta-cell apoptosis and impaired secretory function were partly mediated by interleukin (IL)-1beta and/or high-glucose-induced beta-cell production of IL-1beta. However, the specific signal transduction pathways and molecular events involved in beta-cell dysfunction remain largely unresolved. In this study, we investigated whether Ca(2+) and extracellular signal-regulated kinase (ERK) activation plays a role for IL-1beta action in rat islets.
