Objective:To investigate the immunological effect of Vernonia amygdalina(V.amygdalina) leaf extract and immunace on HIV infected patients taking highly active antiretrwiral therapy. Methods:Fresh V.amygdalina leaves were collected within Nsukka area in Enugu State.The leaves were rinsed with distilled water.Two handful of cleaned fresh leaves were soaked in 200 mL water and squeezed gently by hand to a mixture.Clients were divided into four groups and each group was given different combination.They took the medication for four weeks.The immune effect was tested against marketed immune booster in some retroviral clients.Results:The mean absolute CD4 count was increased in the client who took the extract or supplement.And the clients who took both the extract and supplement had a greater increase in the CD4 count.The increased CD4 was significant as compared with the control group(Pimmunological effect on HIV infected patients. Therefore,we suggest that the V.amygdalina extract or immunace or both could be used as adjuvant in the management of HIV/AIDS clients.

BACKGROUND Recently,there have been several findings that showed intestinal colonisation of Blastocystis hominis(Blastocystis)as a risk factor to the worsening of colorectal cancer(CRC).However,studies have shown controversial results in the pathogenicity of Blastocystis.AIM To review systematically the evidence available on the association between CRC and Blastocystis and the prevalence of Blastocystis in CRC patients and to investigate cytopathic and immunological effects of Blastocystis in in vitro and in vivo studies.METHODS PRISMA guidelines were utilised in conducting this systematic review.Original articles published before February 2,2020 were included.PubMed,Science Direct,Scopus and Google scholar databases were searched.Manual searching was carried out to find articles missed during the online search.RESULTS Out of 12 studies selected for this systematic review,seven studies confirmed the prevalence of Blastocystis and found it to be between 2%-28%in CRC patients,whereby subtype 1 and subtype 3 were predominantly seen.A total of four studies employing in vitro human colorectal carcinoma cell line study models showed significant cytopathic and immunological effects of Blastocystis.In addition,one in vivo experimental animal model study showed that there was a significant effect of infection with Blastocystis on exacerbation of colorectal carcinogenesis.CONCLUSION Blastocystis is a commonly identified microorganism in CRC patients.These studies have provided supportive data that Blastocystis could exacerbate existing CRC via alteration in host immune response and increased oxidative damage.Future studies of CRC and Blastocystis should attempt to determine the various stages of CRC that are most likely to be associated with Blastocystis and its relationship with other intestinal bacteria.

Novel insights for high mobility group box 1 proteinmediated cellular immune response in sepsis:A systemic review

引用

World Journal of Emergency Medicine 2012年第3期3卷 165-171页

作者： Li-feng Huang Yong-ming Yao Zhi-yong Sheng Department of Microbiology and Immunology Burns InstituteFirst Hospital Affiliated to the Chinese People's Liberation Army General Hospital

BACKGROUND:High mobility group box 1 protein(HMGB1) is a highly conserved,ubiquitous protein in the nuclei and cytoplasm of nearly all cell types.HMGB1 is secreted into the extracellular milieu and acts as a proinflammatory cytokine.In this article we reviewed briefly the cellular immune response mediated by HMGB1 in inflammation and sepsis.METHODS:This systemic review is mainly based on our own work and other related reports.RESULTS:HMGB1 can actively affect the immune functions of many types of cells including T lymphocytes,regulatory T cells(Tregs),dendritic cells(DCs),macrophages,and natural killer cells(NK cells).Various cellular responses can be mediated by HMGB1 which binds to cell-surface receptors[e.g.,the receptor for advanced glycation end products(RAGE),Toll-like receptor(TLR)2,and TLR4].Anti-HMGB1 treatment,such as anti-HMGB1 polyclonal or monoclonal antibodies,inhibitors(e.g.,ethyl pyruvate) and antagonists(e.g.,A box),can protect against sepsis lethality and give a wider window for the treatment opportunity.CONCLUSION:HMGB1 is an attractive target for the development of new therapeutic strategies in the treatment of patients with septic complications.
