APN/CD13 inhibitor Ubenimex: A molecular chaperone of antineoplastic chemotherapeutic drugs / 中国药理学通报

Cytotoxic anti-neoplastic drugs are a kind of chemotherapeutic drugs that directly kill or inhibit the growth and proliferation of tumor cells, and it is one of the main drugs for the treatment of malignant tumors. These drugs may have toxic side effects on normal cells of human body (especially those with strong division and proliferation) when they are used to kill tumor cells. And patients may usually have adverse reactions even at a normal dose when using this kind of drugs. Due to the strong toxic side effects of cytotoxic chemotherapeutic drugs, their clinical application is limited. In recent years it has been found that aminopeptidase N inhibitor Ubenimex has a significant synergistic effect with anti-neoplastic chemotherapeutic drugs, which has the advantages of enhancing the therapeutic effect of drugs and reducing the toxic side effects of chemotherapeutic drugs. This review enumerates that the combination of Ubenimex and a variety of cytotoxic drugs can enhance the anti-tumor effect of cytotoxic drugs and reduce the occurrence of adverse reactions. In addition, the mechanism of combined use of Ubenimex in reversing drug resistance is also introduced. At the same time, is is further confirmed the clinical value of Ubenimex as an effective adjuvant in the treatment of malignant tumors, so as to provide a basis for clinical application.

Content comparison of main chemical compositions in Gardenia jasminoids roasted with ginger juice / 中国中药杂志

<p><b>OBJECTIVE</b>To compare the contents of the main chemical compositions in Gardenia jasminoids before and after being roasted with ginger juice.</p><p><b>METHOD</b>Four diterpenoid pigments constituents (C-1, C-2, C-3, crocetin) were determined simultaneously by UPLC on an Agilent Poroshell 120 EC-C18 column at 35 degrees C with the methanol-0.5% formic acid anhydrous in gradient elution as the mobile phrase. The detection wavelength was set at 440 nm and the flow rate was 0.4 mL x min(-1). Two iridoids constituents (G-1, G-2) were determined simultaneously by HPLC on an Agilent TC-C18(2) column at 35 degrees C with acetonitrile-0.5% formic acid anhydrous (18:82) as the mobile phrase. The detection wavelength was set at 238 nm and the flow rate was 1.0 mL x min(-1).</p><p><b>RESULT</b>After being processed with ginger juice, the contents of the diterpenoid pigments constituents decreased slightly and the contents of the iridoids constituents increased slightly.</p><p><b>CONCLUSION</b>The contents of the main chemical compositions in G. jasminoids roasted with ginger juice increased slightly with some regularity, but there were no significant differences.</p>

Effect of fuzheng yiliu granule on nuclear transcriptional factor-kappa B and cell cycle in patients with breast carcinoma / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the effect and clinical significance of Fuzheng Yiliu Granule (FYG) on nuclear transcriptional factor-kappa B (NF-kappa B) and cell cycle in breast tumor.</p><p><b>METHODS</b>Fifty-five patients of breast carcinoma were randomly divided into the treated group and the control group, both were treated with conventional chemotherapy, but to the treated group, FYG was given additionally by oral taking. Operation was performed one month later to take out the tumor tissue for detecting NF-kappa B expression and ration of cells in different phases of cell cycle.</p><p><b>RESULTS</b>Compared with the control group, NF-kappa B expression was significantly increased in the treated group, accompanied with increased G0/1 phase cell proportion and decreased S phase cell proportion as well as significantly reduced cell proliferation index (all P < 0.01).</p><p><b>CONCLUSION</b>FYG could enhance the expression of NF-kappa B in breast tumor tissue, raise the proportion of G0/1 phase cells, decrease proportion S phase cells and reduce the cell proliferation index, showing an active action on the patients prognosis.</p>
