    Abstract Complex diseases always involve some strait episode, such as myocardial hypertrophy and fibrosis caused by hypertension, microcirculation dysfunction and injury in heart, brain, lever, and intestine following ischemia and reperfusion, endotoxin induced multiorgan injury, and recovery after intestinal mucosa damage, for which intervention by a single medicine remains unsatisfied in clinic.Chinese medicine has been applied in clinic for more than two thousand years, which presents as a healthcare system using compound formula preparation, treatment based on syndrome differentiation and individualization thus has advantage in dealing with strait episode of complex diseases. However, the mechanism underlying Chinese medicine is not fully understood up till now.This report will explain the mechanisms underlying the beneficial role of Chinese medicine in therapy of strait episode of complex diseases based on the resent outcomes in study of aforementioned complex diseases. The speaker, using the theory of blood stasis and activating blood to remove stasis in Chinese medicine, classified microcirculation dysfunction induced by different causes, such as ischemia and reperfusion, stress, LPS, common cold, investigated the pathogenesis and progressing of each of which. Furthermore, the report explored the material basis and mechanism for compound formula of Chinese medicine with potential of tonifying Qi and activating blood, removing heat to cool blood, identified the ingredient in the compound formula responsible for respective effect.(Presented at the 1920th Meeting, June 3, 2016).

    Abstract Sorafenib, a multi-targeted tyrosine kinase inhibitor, is a first-line treatment for advanced solid tumors, but it induces many adverse cardiovascular events, including myocardial infarction and heart failure. These cardiac defects can be mediated by alternative splicing of genes critical for heart function. Whether alternative splicing plays a role in sorafenib-induced cardiotoxicity remains unclear. Transcriptome of rat hearts or human cardiomyocytes treated with sorafenib was analyzed and validated to define alternatively spliced genes and their impact on cardiotoxicity. In rats, sorafenib caused severe cardiotoxicity with decreased left ventricular systolic pressure, elongated sarcomere, enlarged mitochondria and decreased ATP. This was associated with alternative splicing of hundreds of genes in the hearts, many of which were targets of a cardiac specific splicing factor, RBM20. Sorafenib inhibited RBM20 expression in both rat hearts and human cardiomyocytes. The splicing of RBM20's targets, SLC25A3 and FHOD3, was altered into fetal isoforms with decreased function. Upregulation of RBM20 during sorafenib treatment reversed the pathogenic splicing of SLC25A3 and FHOD3, and enhanced the phosphate transport into mitochondria by SLC25A3, ATP synthesis and cell survival.We envision this regulation may happen in many drug-induced cardiotoxicity, and represent a potential druggable pathway for mitigating sorafenib-induced cardiotoxicity.

    Abstract Ethnopharmacological relevant: YangXueQingNaoWan (YXQNW), a compound Chinese medicine, has been widely used for dizziness, irritability, insomnia, and dreaminess caused by blood deficiency and liver hyperactivity in China. However, whether YXQNW can inhibit cerebral microvascular exudation and cerebral hemorrhage (CH) caused by blood brain barrier (BBB) damage after tissue plasminogen activator (tPA) still unknown.
    Aim of the research: To observe the effect of YXQNW on cerebral microvascular exudation and CH after tPA and investigate its mechanism in protecting BBB.
    Materials and methods: Male C57BL/6 N mice suffered from ischemia stroke by mechanical detachment of carotid artery thrombi with the stimulation of ferric chloride. Then mice were treated with tPA (10 mg/kg) and/or YXQNW (0.72 g/kg) at 4.5 h. Cerebral blood flow (CBF), infarct size, survival rate, neurological scores, gait analysis, Evans blue extravasation, cerebral water content, fluorescein isothiocyanate-labeled albumin leakage, hemorrhage, junction and basement membrane proteins expression, leukocyte adhesion and matrix metalloproteinases (MMPs) expression were evaluated 24 h after tPA. Proteomics was used to identify target proteins.
    Results: YXQNW inhibited cerebral infarction, neurobehavioral deficits, decreased survival, Evans blue leakage, albumin leakage, cerebral water content and CH after tPA thrombolysis; improved CBF, low-expression and degradation of junction proteins, basement membrane proteins, Arhgap21 and its downstream α-catenin and β-catenin proteins expression; and suppressed the increase of adherent leukocytes and the release of MMP-9 derived from macrophage.
    Conclusion: YXQNW relieved BBB damage and attenuated cerebral microvascular exudation and CH after tPA thrombolysis. The effect of YXQNW on cerebral microvascular exudation was associated with the inhibition of the low-expression of junction proteins, especially AJs mediated by Rho GTPase-activating protein 21 (Arhgap21), while the effect on CH was associated with the inhibition of leukocyte adhesion, the release of MMP-9 derived from macrophage, and low-expression and degradation of collagen IV and laminin in the vascular basement membrane.

    Abstract The Chinese medicine formula Chanling Gao (CLG) exhibits significant tumor inhibitory effects in colorectal cancer (CRC) nude mice. However, the detailed mechanisms remain elusive. CRC in situ nude mouse models were treated with CLG. Small animal magnetic resonance imaging (MRI) tracked tumor progression, and overall health metrics such as food and water intake, body weight, and survival were monitored. Posttreatment, tissues and blood were analyzed for indicators of tumor inhibition and systemic effects. Changes in vital organs were observed via stereoscope and hematoxylin-eosin staining. Immunohistochemistry quantified HIF-1α and P70S6K1 protein expression in xenografts. Double labeling was used to statistically analyze vascular endothelial growth factor (VEGF) and CD31 neovascularization. Enzyme-linked immunosorbent assay was used to determine the levels of VEGF, MMP-2, MMP-9, IL-6, and IL-10 in serum, tumors, and liver. Western blotting was used to assess the expression of the PI3K/Akt/mTOR signaling pathway-related factors TGF-β1 and smad4 in liver tissues. CLG inhibited tumor growth, improved overall health metrics, and ameliorated abnormal blood cell counts in CRC nude mice. CLG significantly reduced tumor neovascularization and VEGF expression in tumors and blood. It also suppressed HIF-1α, EGFR, p-PI3K, Akt, p-Akt, and p-mTOR expression in tumors while enhancing PTEN oncogene expression. Systemic improvements were noted, with CLG limiting liver metastasis, reducing pro-inflammatory cytokines IL-6 and IL-10 in liver tissues, decreasing MMP-2 in blood and MMP-2 and MMP-9 in tumors, and inhibiting TGF-β1 expression in liver tissues. CLG can enhance survival quality and inhibit tumor growth in CRC nude mice, likely through the regulation of the PI3K/Akt/mTOR signaling pathway.

    Abstract Objective: To investigate the effect of Yiqifumai injection (YQFM), a compound Chinese medicine, and its main active ingredients on lipopolysaccharide (LPS)-induced microvascular disturbance in mesentery and ileum.
    Methods: Rats were infused with LPS (5 mg/kg/h) for 90 min. Thirty minutes after initiation of LPS administration, YQFM (160 mg/kg/h), Rb1 (5 mg/kg/h), Sch (2.5 mg/kg/h), or Rb1+Sch (5 mg/kg/h + 2.5 mg/kg/h) was infused until 90 min. Human umbilical vein endothelial cells (HUVECs) were incubated with LPS (100 ng/ml) for 90 min. YQFM (1 mg/ml), Rb1 (100 µM), Sch (100 µM), or Rb1+Sch (200 µM) was added 30 min after initiation of LPS stimulation.
    Results: Yiqifumai injection and Rb1+Sch inhibited mesenteric venule hyperpermeability, suppressed microvillar erosion and submucosal edema, and protected claudin-5 from downregulation and interleukin-1β from upregulation in ileal tissues after LPS. Study in HUVECs confirmed the effect of YQFM and Rb1+Sch on JAM-1 after LPS and revealed a similar effect on other junction proteins. Moreover, YQFM and Rb1+Sch attenuated the dysfunctional energy metabolism and the activation of TLR-4/Src/NF-κB signaling with Rb1 and Sch being partially effective.
    Conclusion: These results demonstrated the beneficial effect of post-treatment with YQFM, which is attributable to its main ingredient Rb1 and Sch, and likely mediated by targeting TLR-4/Src/NF-κB signaling pathway.

    Abstract Coronary heart disease remains a major threaten for public health worldwide, and pharmacological or mechanical coronary reperfusion are currently used for treatment of acute coronary syndrome. However, restoration of blood flow to ischemic myocardium leads to ischemia/reperfusion (I/R) injury. Microcirculatory disturbance and cardiac injury after I/R occur via a complex pathologic process including metabolism impairment in the ischemia phase and oxidative stress in the reperfusion phase. Obviously, any treatment targeting a single link is insufficient to cope with I/R injury. Investigation in the past decade in our laboratory as well as in other's demonstrated the cardioprotection potential of QiShenYiQi Pills (QSYQ) and ingredients in experimental animal models of I/R injury. These results have offered insight into the mechanism thereby QSYQ prevents against cardiac I/R injury in clinic. This review will outline the results with respect to the effect of QSYQ and major bioactive ingredients on I/R-induced microcirculatory disturbance, cardiac injury and fibrosis, with emphasis on the underlying mechanisms.

    Abstract This study investigated the roles of bone morphogenetic protein-4 (BMP4) and ROS in diabetic endothelial dysfunction and explored whether Salvianolic acid B (Sal B) improved endothelial function by affecting BMP4-ROS in diabetic mice.db/db mice were orally administrated with Sal B (10 mg/kg/day) for one week while db/m + mice were injected with adenoviral vectors delivering BMP4 (3 × 10⁸ pfu) and then received one week-Sal B treatment. ROS levels were assayed by DHE staining. Protein expression and phosphorylation were evaluated by Western blot. Aortic rings were suspended in myograph for force measurement. Flow-mediated dilatations in the second-order mesenteric arteries were determined by pressure myograph.We first revealed the existence of a BMP4-ROS cycle in db/db mice, which stimulated p38 MAPK/JNK/caspase 3 and thus participated in endothelial dysfunction. One week-treatment or 24 h-incubation with Sal B disrupted the cycle, suppressed p38 MAPK/JNK/caspase 3 cascade, and improved endothelium-dependent relaxations (EDRs) in db/db mouse aortas. Importantly, in vivo Sal B treatment also improved flow-mediated dilatation in db/db mouse second order mesenteric arteries. Furthermore, in vivo BMP4 overexpression induced oxidative stress, stimulated p38 MAPK/JNK/caspase 3, and impaired EDRs in db/m + mouse aortas, which were all reversed by Sal B.The present study demonstrates that Sal B ameliorates endothelial dysfunction through breaking the BMP4-ROS cycle and subsequently inhibiting p38 MAPK/JNK/caspase 3 in diabetic mice and provides evidence for the additional new mechanism underlying the benefit of Sal B against diabetic vasculopathy.
