Methods: Thrombin (50 U/mL) was incubated in human umbilical vein endothelia cells (HUVECs) with 50 and 100 μg/L (1:0, 0:1, 3:1, 2:1, 1:1, and 1:2) salvianolic acids and tanshinones or without the components of Danshen extract. Cell viability was confirmed in (4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium (MTT) assay and cell death was confirmed in lactate dehydrogenase (LDH) released into the cell culture supernatant.

A set of central composite design experiments were designed by using four factors which were ethanol amount, ethanol concentration, refrigeration temperature and refrigeration time. The relation between these factors with the target variables of the retention rate of schizandrol A, the soluble solids content, the removal rate of fructose and the removal rate of glucose were analyzed with Bayesian networks, and ethanol amount and ethanol concentration were found as the critical process parameters. Then a network model was built with 2 inputs and 4 outputs using back propagation artificial neural networks which was optimized by genetic algorithms.

A new risk analysis method based upon reliability theory was introduced in this paper for the quality risk management of Chinese medicine injection manufacturing plants. The risk events including both cause and effect ones were derived in the framework as nodes with a Bayesian network analysis approach. It thus transforms the risk analysis results from failure mode and effect analysis (FMEA) into a Bayesian network platform.

Despite many successful applications of Chinese herbal medicine (CHM) in the treatment and prevention of neurological diseases (ND), the fully scientific understanding of CHM's action mechanisms had been hampered for lack of appropriate methods to explore the combinatorial rules, the synergistic mechanisms, and the molecular basis of CHM. As an improved pharmacology approach, cerebrospinal fluid pharmacology (CSFP), based on the fact that cerebrospinal fluid plays an important role in the health maintenance of specific survival environment for neurons and glial cells, has been constructed and applied to CHM research for treating ND. In the present review, the concept and advantages of CSFP are briefly introduced.

Methods: The production of nitric oxide (NO), tumor necrosis factor α (TNF-α), and interleukin-1β (IL-1β) induced by lipopolysaccharide (LPS) treatment in rat primary cultured microglia were measured by Griess reaction or enzyme-linked immunosorbent assay. Cell viability of cortical neurons was measured using AlamarBlue reagent.
An increasing number of studies has indicated that hypoxic-ischemic-induced cerebral injury is partly mediated via oxidative stress. Recent researches have focused on searching for drug and herbal manipulations to protect against hypoxic-ischemic-induced oxidative cell damage. Scutellarin is a flavonoid derived from the Erigeron breviscapus (vant.
