Mechanism of Gardenia jasminoides against cholestasis based on network pharmacology / 中国中药杂志

To screen the active ingredients of Gardenia jasminoides and potential targets,and investigate the mechanisms against cholestasis based on network pharmacology technology. Twenty-one active components of G. jasminoides were retrieved and the target sites were screened by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform( TCMSP). Cytoscape3. 2. 1 was used to construct the component-target network. Two hundred and eight targets related to cholestasis were searched and screened through Dis Ge NET,KEGG and OMIM databases. The key targets of G. jasminoides components and cholestasis were integrated and screened,and the component-target-disease network was constructed with Cytoscape 3. 2. 1 software to screen out the core network whose freedom degree was greater than the average value. The Clue GO plug-in of Cytoscape 3. 2. 1 software was used to analyze the biological processes and pathway enrichment of G. jasminoides in regulation of cholestasis. GO biological process analysis revealed 17 biological processes,involving 3 signaling biological processes related to cholestasis,i.e. acute inflammatory response,positive regulation of reactive oxygen species metabolic process,and nitric oxide biosynthetic process. KEGG-KEEG-305 terms and REACTOME pathways analysis revealed 17 regulatory pathways,involving 4 signaling pathways related to cholestasis,i.e. metabolism of xenobiotics by cytochrome P450,nuclear receptor transcription pathway,GPVI-mediated activation cascade and platelet activation. It was found that aqueous extract of G. jasminoides could improve serum biochemical abnormalities in ANIT-induced cholestasis rats. Aqueous extract of G. jasminoides could decrease the protein and mRNA expression levels of ESR1 in liver tissues,and increase the protein and mRNA expression levels of PPARG,NOS2,F2 R,NOS3,and NR3 C1. To sum up,the possible mechanisms of G. jasminoides against cholestasis may be related with the above three processes and four pathways.

Alteration of renal hemodynamic in adriamycin-induced nephrosis rats administrated with Wulingsan / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the effect of traditional classical compound Wulingsan on renal hemodynamic in rats with adriamycin (ADR)-induced nephrosis.</p><p><b>METHOD</b>After establishing a model of rats with adriamycin-induced nephrosis, we administrated wulin-san to the ADR rats via oral gavage for four weeks and measured mean arterial blood preasure (MABP) with manometer. Renal clearance of paraaminohippuric acid (PAH) and inulin were detected, then renal plasma flow (RPF) and glomerular filtration rate (GFR) were calculated. Renal vascular resistance (RVR) was calculated as the division of MABP by RPF. Renal endothelin (ET) and angiotensin II (Ang II) were detected with radioimmunity assay kits, and nitrous oxide (NO) was detected with biochemical kits.</p><p><b>RESULT</b>There was no significant change of GFR in ARD rats, but RPF and NO were decreased, which accompanied by enhanced RVR, ET and Ang II. RPF was increased in the administrated rats, in company with RVR, ET and Ang II decreased, whereas NO was not influenced after the administration.</p><p><b>CONCLUSION</b>Wulingsan can improve the renal hemodynamic in ADR rats, at least in part by modulating the levels of vasoactive factor.</p>

Review and analysis of present status of the micronization of Chinese traditional medicine / 中国中药杂志

Micronization is one of the methods to improve the solubility and bioavailability of drug, the micronization of TCM is a new techonology of TCM mordenization. status in quo of TCM micronization was reviewed and analyzed. Effects of micronization on the dissolution of active ingredients and pharmacological action were widely studied, however some fundmental aspects, such as engineering factors of superfine powder preparation, stability of them and the optimal particle size, are urgently to be studied.

Effect of borneol on the intercellular tight junction and pinocytosis vesicles in vitro blood-brain barrier model / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the mechanism of borneol in opening the blood-brain barrier (BBB).</p><p><b>METHODS</b>Borneol contained serum was prepared and using Matin-Darby canine kidney epithelium (MDCKE) cell line as the in vitro BBB model to observe the effects of borneol on intercellular tight junction (ICTJ) and pinocytosis vesicles of BBB model.</p><p><b>RESULTS</b>Borneol reduced the ICTJ and caused increase of the number and enlarged the diameter of vesicles. The ICTJ was opened firstly 4 hrs after borneol treatment, then the pinocytosis was affected 24 hrs later. The effects disappeared 24 hrs after removal of the borneol contained serum, indicating that the above-mentioned effects were reversible.</p><p><b>CONCLUSION</b>Borneol could obviously loosen the ICTJ in BBB, accelerate the transportation of substance through the intercellular passage, it also could increase the number and volume of pinocytosis vesicles in BBB cells, thus to accelerate the transportation of substance by way of cell pinocytosis.</p>
