OBJECTIVEA sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method has been developed and validated for the determination of brucine and strychnine in rat plasma.
METHODSamples were extracted by ethyl acetate-n-butanol (7: 3). Chromatographic separation was operated on ZORBAX XDB-C18 column with gradient elution of acetonitrile-methanol-water (0.05% acetic acid and 10 nmol x L(-1) ammonium formate contained), followed by LC-MS/MS in positive electrospray ionization. Quantification was carried out on multiple reaction monitoring (MRM) of the transition m/z 395.2/324.2, m/z 335.2/184.2 and m/z 199.1/171.1 for brucine, strychnine and tacrine (internal standard), respectively.
RESULTThe method was linear in the range of 0.195-100 and 0.07840 microg x L(-1) for brucine and strychnine, with coefficient correlation 0.994 and 0.996 respectively. The recoveries of extraction were 78.9% - 102.4% for brucine and 95.2% - 106.1% for strychnine. Precision, accuracy, stability and matrix effect of the analytes met the requirement. The method was applied to a pharmacokinetic study of brucine and strychnine after cutaneous administration of Semen Strychni niosome gel. The C(max) were (26.20 +/- 5.81) and (12.50 +/- 3.00) microg x L(-1) while the AUC(0-infinity), were (193.75 +/- 39.43) and (98.25 +/- 28.54) microg x h x L(-1) of the two components.
CONCLUSIONWe conclude that the niosomes may reduce the systemic exposures and prolong the local release of brucine and strychnine.

Fibrosis can occur in diverse tissue and organs and is the common outcome as multiple chronic diseases progress. It is characterized by over-activation of fibroblasts and excessive deposition of extracellular matrix. Targeting transforming growth factor-β (TGF-β), a classical signaling molecule in fibrosis, is currently a routine strategy for drug therapy of this disease. The use of traditional Chinese medicine (TCM) in the treatment of fibrotic diseases has been supported by mature theories. The theories emphasize that the internally-accumulated pathogens and mixed deficiency-excess underlie the shared pathology of fibrotic diseases. Qi stagnation, blood stasis, phlegm turbidity, and mass accumulation are key pathological factors. "Yin suppression by Yang" is the core thought for treatment with TCM of the disease. Pharmacological investigations reveal the scientific nature of TCM in treating fibrotic diseases, namely multilevelled and multitargeted. In other words, it refers to networked regulation of signaling activities of fibrosis-related molecules such as TGF-β/Drosophila protein homolog (Smad), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), Hedgehog, Wnt/β-catenin, and inflammatory cytokines, so as to inhibit fibroblast function and provide a promising insight into novel anti-fibrotic drug. This paper summarized the conventional understanding of fibrotic disease treatment with TCM and its mechanism of action by reviewing ancient literature and modern research reports, which offers an idea for follow-up research in this field.

OBJECTIVETo investigate clinicopathological features, immunophenotype and differential diagnosis of intravenous leiomyomatosis with intracardiac extension.
METHODSClinical manifestations, morphologic features, and immunohistochemical staining were retrospectively analyzed in 19 cases of intravenous leiomyomatosis with intracardiac extension.
RESULTSThe patients' age ranged from 33 to 59 years (mean 44 years). Clinical presentation included chest tightness, palpitation, dyspnea, edema of low extremity, abdominal distention or hypermenorrhea. However, a few patients were asymptomatic. Grossly, intravenous leiomyomatosis in most cases demonstrated coiled or nodular growth within the myometrium with worm-like involvement of the uterine vein in broad ligament or other pelvic veins with continued extension into the vena cava and the heart. The intravenous tumor surface was generally smooth and rubbery, with a greyish-white color. Microscopically, the tumors were composed of spindle cells with rare mitotic figures and the presence of abundant thick-walled vessels. Marked fibrosis, hyalinization, myxoid and edematous changes were common. The tumor cells were positive for SMA, ER, PR and desmin but negative for HMB45 and S-100. CD10 and CD34 were positive in 4 patients and negative in the remaining cases.
CONCLUSIONIntravenous leiomyomatosis with intracardiac extension is a rare disease among women of child-bearing age, with specific morphologic manifestations and immunohistochemical profiles.
