ABSTRACT
Alpha-particles, which have strong cytotoxicity, could reduce radiation damage to surrounding tissues, and stimulate anti-tumor immune response, so they have good development prospect in cancer treatment. The current researches show that α-emitting radionuclides increase the presentation of major histocompatibility complex-I (MHC-Ⅰ) on tumor cells and induce immunogenic cell death (ICD) to activate immune response mediated by CD8 + T cells. As two methods of α-therapy, α radioimmunotherapy and diffusing α-emitters radiation therapy (DART) further enhance the anti-cancer effect when combined with immunotherapy. The methods of immunotherapy include adoptive cell therapy (ACT), immune checkpoint blockade, neutralization of immunosuppressive cells and immunoadjuvant. This article reviews the characteristics of α-particles for cancer treatment, the mechanism of immune response induced by ionizing radiation (including α-radionuclides) and the related research of α-therapy combined with immunotherapy.
ABSTRACT
With high linear energy transfer (LET) and short transmission distance, targeted α-therapy (TAT), as a specific targeted tumor treatment, can improve the killing effect on microscopic lesions or diffuse micrometastases. It can reduce bone marrow toxicity and overcome the problem of radiotherapy tolerance in hypoxic tumors. α-emitters and their labeled drugs are constantly being studied, and further research is needed to promote the development of clinical applications.
ABSTRACT
The liver in the traditional Chinese medicine (TCM) theory of visceral manifestation has rich connotations. Thestructure and function of liver differed from that of liver in modern recognition. Research on TCM theory has partiallyexplained the liver theory. The function of controlling dispersion of liver was associated with neuro-endocrine-immunesystem, liver sinus endothelial function, and metallothionein, etc. While the activity of storing blood of liver related withblood coagulation factors, anticoagulant and so on. The functional interaction between Zang-organ and Fu-organ maycorrelate with the lung-liver axis and liver-intestine axis. The review summarized the modern explanation on liverfunction in TCM and its relationship with Fu-organs to help the development of TCM basic theory in liver function.
ABSTRACT
In the long course of traditional Chinese medicine (TCM) development history,generations of physicians in their long-term medical practice,have paid attention to assimilate and apply new technology and new theory,constantly enrich and perfect the medical technologies,methods and theory systems.It is particularly important to promote the innovation of TCM theory and guide the clinical application of TCM through the learning and absorption of advantages from modern technologies and biomedicine to transform as part of TCM,and then,to expatiate with TCM language.It is especially important in the promotion of TCM theory innovation and clinical guidance of TCM practice.This paper overviewed the common points between TCM and modern medicine from the aspects of balance and steady state of organism,zangfu-organ relationship,etiology and pathogenesis,syndrome differentiation methods,compatibility of Chinese herbal medicine and formula,medicinal properties and pharmacology,etc.The feasibility of applying modern medicine in the interpretation of TCM and its development prospects was expatiated.It provided new ideas and new methods in TCM development.
ABSTRACT
This study was aimed to predict active compounds,drug targets and potential diseases of Yi-Guan decoction (YGD) by network pharmacological technology,and to clarify molecular mechanisms of YGD efficiency on different diseases with liver and kidney yin deficiency syndrome (LKYDS).Chemistry compounds,targets and related diseases from YGD were collected from TCMSP,TCM Database@Taiwan,TCMID,HIT,Drugbank,PubChem and TTD databases.The YGD compounds-targets-diseases network was constructed.The network topology was analyzed by Cytoscape software.The analysis of GO biological processes and KEGG pathways enrichment were performed by DAVID website.The results showed that 849 chemical compounds were identified from Beishashen,Maidong,Danggui,Shengdihuang,Chuanlianzi and Gouqizi.There were 49 active CHM compounds that were both oral bioavailability (OB) ≥ 30％ and drug-likeness (DL) ≥ 0.18,corresponding to 200 target proteins and 264 diseases.The top three GO biological processes were response to organic substance,regulation of cell proliferation,and response to endogenous stimulus,respectively.The top three KEGG pathways were pathways in cancer,hepatitis B,and prostate cancer,respectively.It was concluded that the analysis on YGD was conducted based on network pharmacology,and the compound-target-disease network was built,which may help to clarify the mechanisms of YGD efficiency on different diseases with LKYDS.It can provide clues to find new potential clinical adaptation of disease and new drugs.
