Danhong injection is a compound preparation of traditional Chinese medicine Salvia miltiorrhiza and Carthamus tinctorius, and has been widely applied in treating coronary heart diseases and ischemic encephalopathy in clinic. Despite the complexity of its chemical compounds and the diversity of targets, especially in system biology, there have not a report for its action mechanism as a whole regulatory biological network. In this study, protein data of S. miltiorrhiza and C. tinctorius were searched in TCMGeneDIT database and agilent literature search (ALS) system to establish the multi-component protein network of S. miltiorrhiza, C. tinctorius and Danhong injection. Besides, the protein interaction network was built based on the protein-protein interaction in Genecards, BIND, BioGRID, IntAct, MINT and other databases. According to the findings, 10 compounds of S. miltiorrhiza and 14 compounds of C. tinctorius were correlated with proteins. The 24 common compounds had interactions with 81 proteins, and formed a protein interaction network with 60 none-isolated nodes. The Cluster ONE module was applied to make an enrichment analysis on the protein interaction network and extract one sub-network with significant difference P <0.05. The sub-network contains 23 key proteins, which involved five signaling pathways, namely Nod-like receptor signaling pathway, epithelial cell signaling in helicobacter pylori infection, Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway and neurotrophin signaling pathway through KEGG signaling pathway mapping. In this study, the computational system biology approach was adopted to preliminarily explain the molecular mechanism of main compounds of Danhong injection in preventing and treating diseases and provide reference for systematic studies on traditional Chinese medicine compounds.

Journal of Experimental Hematology 2008;16(2):231-239
Multiple myeloma is a neoplasm of mature and immature plasma cells, it remains an incurable disease using conventional chemotherapy and increasing aggressive approaches. In recent years, due to the better understanding of myeloma biology, genetics and tumor formation, there are lots of new active drugs or combinational chemotherapy regimens having been developed, such as proteasome inhibitors, immunomodulatory agents etc, they are more effective than conventional chemotherapy. This article summarizes the recent advances with the new options for the treatment of multiple myeloma.

Objective To investigate the correlation between vertical infection of hepatitis B virus(HBV) and Hofbauer cell in placenta.Methods Placental structural change,the correlation between HBV infection and Hofbauer cell in 14 vertical transmission cases(HBsAg and HBV-DNA seropositive in both mothers and their neonates),62 non-vertical transmission cases(HBsAg and HBV-DNA seropositive in mothers,but HBsAg and HBV-DNA seronegative in their neonates) and 10 controls(HBsAg and HBV-DNA seronegative in both mothers and their neonates) were determined by inmumohistochemical techniques and photomicroscopy.Results 1.necrosis,edema,villi capillary sclerosis,intravillifibrosis,fibrinoial sendimentation,morphokarrioleukocyet,lymphacyte,granulocyte were observed in placentas both vertical transmission cases and non-vertical transmission cases.2.Placental HBsAg postive rate in vertical transmission cases was 100%,but 58% in non-vertical transmission cases.There was significant difference in two groups(P=(0.013)).The positive sign was observed in trophoblast cell,Hofbauer cell and endothelial cell.3.Total Hobauer cell and ones combined with HBV in placentas of vertical transmission cases obviously increased(P

OBJECTIVE:
To establish the method to analyze γ-hydroxybutyric acid (GHB) and its precursors 1,4-butanediol (1,4-BD) and gamma-butyrolactone (GBL) in urine through LC-MS/MS and provide evidence for related cases.
METHODS:
GHB-d6 and MOR-d3 were used as the internal standard. The urine sample was separated by LC after protein precipitation with methanol. The electrospray ion source was for ionization. Each compound was detected through multiple-reaction monitoring (MRM) mode.
RESULTS:
The limits of detection of GHB and its precursors 1,4-BD and GBL were 0.1, 0.1 and 2 μg/mL. The accuracy was 87.6%-98.1%. The intra-day and inter-day precisions were less than 15% and matrix effects were higher than 80%.
CONCLUSION
The method is high sensitive, simple, rapid, specific and with high reliability. This study has provided technical support and basic data for forensic cases involving GHB.

ObjectiveTo observe the effect of rat cerebral hemorrhage model via autologous blood injection.MethodsBlood extracted from rats' cardiac ventricles was injected into the right caudate nucleus via stereotactic method. Pathological examination,ultrastructural visualization and motor functional test were applied to validate the feasibility of this method.ResultsRats showed paralysis of left extremities rapidly after surgery. Pathological examination confirmed the formation of hematoma in caudate nucleus. The deviation of hematoma volume and location among individuals was significantly lower than that of rats made by collagenase injection. Transmission electron microscopy showed wide mylin degeneration in right caudate nucleus. Motor functional test revealed the dysfunction of left extremities with marked lower deviation among individuals compared with that of collagenase injection (P<0.05).ConclusionAutologous blood injection can result in significantly lower deviation of hematoma volume and location as well as dysfunctional degree compared with that of collagenase injection.
