To study the alkaloids of Voacanga africana. The alkaloids were isolated by normal phase silica gel and Sephadex LH-20 column chromatography. Their structures were elucidated by analysis of spectroscopic data. Eight alkaloids were isolated and their structures were elucidated as voacangine(1), voacangine hydroxyindolenine(2), 19R-epi-voacristine(3), epi-ibogaine(4), vobasine(5), 19-epi-heyneanine(6), vobtusine(7) and voacamine(8). Compounds 2-4 and 6 are isolated from this plant for the first time. Source

Despite substantial progress that has been made in understanding many aspects regarding biology and pathogenesis of human immunodeficiency virus type 1 (HIV-1), there is currently no vaccine or curative treatment available. HIV-1 continues to be a major global health problem. In this regard, new strategies are required for promoting a complete immune reconstitution and eradicating the virus from the body. The rationale for the use of hematopoietic stem cell (HSC)-based gene therapy against HIV infection is that, after transplantation, genetically modified HSCs carrying anti-HIV transgenes would engraft, divide and differentiate into large numbers of mature myeloid and lymphoid cells that express antiviral genes and thus are protected from HIV invasion or productive replication. HIV-1 attachment to susceptible cells involves binding of gp120 to CD4 receptor and subsequently to a HIV co-receptor, either CCR5 or CXCR4. The pivotal role of CCR5 in HIV-1 acquisition and disease progression has been established by the discovery of a naturally occurring 32-bp deletion in CCR5 (CCR5Δ32) which generates a nonfunctional gene product. Homozygosity for CCR5 Δ32 confers profound resistance against HIV infection, and heterozygous mutation that induces a decrease in CCR5 surface expression is associated with lower plasma viral load and delayed progression to acquired immune deficiency syndrome (AIDS). This, together with the fact of R5 dominance during the acute and asymptomatic phase, suggests that CCR5 is an attractive target for HIV gene therapeutics. The present review addresses recent advances of CCR5-targeted HSC gene approaches to treat HIV infection, discusses the future prospects and postulates potential strategies in the field. © 2012 Bentham Science Publishers.

To study the influences of warming kidney prescription on antiviral therapeutic efficacy and creatine kinase (CK) level in telbivudine-treated HBeAg-positive chronic hepatitis B patients with kidney yang deficiency syndrome. Ninety-six cases were enrolled and randomly divided into two groups (n=48 each): warming kidney prescription treatment or control. Both groups were treated for 52 weeks with telbivudine monotherapy, but the treatment group received additional treatment with the warming kidney prescription. Traditional Chinese medicine (TCM) syndrome score, biochemical response, virological response, serological response, CK level, and adverse reactions were recorded for each group in order to perform comparative analysis of the warming kidney prescription's effects. A total of 84 patients, including 43 cases in the treatment group, completed the study. The warming kidney prescription led to significantly improved total clinical syndrome efficacy, TCM syndrome score, biochemical response, virological response, and HBeAg serological responses, as evidenced by changes for each parameter observed in the treatment group versus the control group (respectively, 88.37% vs. 63.41%, 4.97+/-1.88 vs. 10.13+/-3.72, 95.35% vs. 75.61%, 81.40% vs. 56.10%, 48.84% vs. 26.83% (all, P less than 0.05)). No patient in either group experienced primary treatment failure. Seven cases, all from the control group, experienced virological breakthrough. Elevated CK was observed in both the treatment and control groups, but significantly more patients in the control group experienced this adverse reaction (respectively, 73.17% vs. 44.19%; P less than 0.01). The warming kidney prescription can increase telbivudine antiviral therapeutic efficacy and decrease the telbivudine-induced increase in creatine kinase in HbeAg-positive chronic hepatitis B patients with kidney yang deficiency syndrome.

Ethnopharmacological relevance Rheum rhabarbarum (rhubarb) has long been used for the treatment of inflammation in China and other Asian countries. However, the mechanism underlying the anti-inflammatory activity of this medicinal plant is not fully understood. The present study was designed to investigate the anti-inflammatory effects of anthraquinones, the major constituents in rhubarb, and the molecular mechanism involved in their anti-inflammatory effects. Materials and methods RAW264.7 cells were stimulated by lipopolysaccharide (LPS) in the presence or absence of the compounds examined. The proliferation of RAW264.7 cells was assayed by the Alamar-Blue method. The quantity of nitric oxide (NO) was determined by Griess assay. The expression of pro-inflammatory cytokines was determined by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time PCR. Inducible nitric oxide synthase (iNOS), inhibitor of nuclear factor κBα (IκBα), extracellular signal-regulated kinase (ERK), p38 mitogen-activated protein kinase (MAPK), c-Jun NH2-terminal kinase (JNK), and Akt/phosphoinositide 3-kinase (PI3K) protein expression levels were determined by Western blotting. Results Aloe-emodin markedly suppressed the production of NO, interleukin-6 (IL-6), and interleukin-1β (IL-1β) in LPS-stimulated RAW264.7 cells with no apparent cytotoxicity. The mRNA expression levels of iNOS, IL-6, and IL-1β genes were also significantly inhibited by aloe-emodin. Western blot analysis showed that aloe-emodin suppressed LPS-induced iNOS protein expression, IκBα degradation, and the phosphorylation of ERK, p38, JNK, and Akt. Conclusions These results demonstrate that aloe-emodin is the bioactive component of rhubarb that confers an anti-inflammatory effect through a likely mechanism involving a decrease in pro-inflammatory cytokine production in LPS-induced RAW264.7 macrophages via inhibition of NF-κB, MAPK, and PI3K pathways. © 2014 Elsevier Ireland Ltd.

Our research is motivated by 2 methodological problems in assessing diagnostic accuracy of traditional Chinese medicine (TCM) doctors in detecting a particular symptom whose true status has an ordinal scale and is unknown-imperfect gold standard bias and ordinal scale symptom status. In this paper, we proposed a nonparametric maximum likelihood method for estimating and comparing the accuracy of different doctors in detecting a particular symptom without a gold standard when the true symptom status had an ordered multiple class. In addition, we extended the concept of the area under the receiver operating characteristic curve to a hyper-dimensional overall accuracy for diagnostic accuracy and alternative graphs for displaying a visual result. The simulation studies showed that the proposed method had good performance in terms of bias and mean squared error. Finally, we applied our method to our motivating example on assessing the diagnostic abilities of 5 TCM doctors in detecting symptoms related to Chills disease. © The Author 2011.
