After murine fetal liver cells (FLC) were transfected with granulocyte-macrophage colony-stimulating factor (GM-CSF) gene by recombinant adenovirus and intrasplenically transplanted into allogeneic mice, the effects of GM-CSF gene-transfected FLC on the recovery of immune response inhibited by chemotherapy were observed. The number of CD4 + cells and the ratio of CD4 + /CDS + cells from peripheral blood lymphocytes increased significantly. The cytotoxicity of the NK cells and the proliferation response of splenocytes to ConA, LPS elevated markedly, but the same results were not from bone marrow. These data demonstrated that intrasplenic transplantation of GM-CSF gene-transfected FLC could effectively accelerate the recovery of immune response after high-dose chemotherapy.

Psoriasis is a non-infectious chronic inflammatory skin disease. It′s acknowledged that interleukin (IL)-17 signaling pathway dominantly drives the development of psoriasis. Recently, the role of neuro-immune axis in psoriasis has attracted widespread attention. Lidocaine, a local anesthetic, has ability to block the conduction of nerve impulses, while its therapeutic efficacy on psoriasis remains to be confirmed. Here, we evaluated the therapeutic efficacy of topical application of compound lidocaine cream (LIDO) on imiquimod (IMQ)-induced mouse psoriasis model. Animal welfare and experimental procedures follow the regulations of the Ethics Committee of China Pharmaceutical University. The psoriasis area and severity index (PASI) scoring was used to evaluate the severity of psoriasis-like symptoms. Hematoxylin-eosin staining was used to examine histopathological changes and epidermal thickness was measured. Ki67 immunofluorescence staining was used to evaluate the proliferation of keratinocytes. The relative mRNA expression of inflammatory cytokines (including

OBJECTIVETo compare the difference of Euphorbia Pekinensis Radix before and after being processed with vinegar in the toxicity on rat small intestinal crypt epithelial cells IEC-6, and make a preliminary study on the mechanism of detoxication of Euphorbia Pekinensis Radix processed with vinegar.
METHODWith rat small intestinal crypt epithelial cells IEC-6 as the study object, the MTT method was adopted to detect the effect of Euphorbia Pekinensis Radix before and after being processed with vinegar on IEC-6 cell activity. The morphology of cells were observed by the inverted microscope. The down-regulated mitochondrial apoptosis pathway of enterocytes caused by the vinegar processing was analyzed by using the high content screening.
RESULTCompared with the negative control group, the proliferation inhibition experiment showed that Euphorbia Pekinensis Radix showed a relatively high intestinal cell toxicity (P < 0.01). The results of HCS analysis showed that Euphorbia Pekinensis Radix could significantly reduce the cell nucleus Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.01), and increase Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.01). After being processed with vinegar, compared with Euphorbia Pekinensis Radix groups with different doses, Euphorbia Pekinensis Radix processed with vinegar could significantly decrease the cell proliferation inhibition effect on enterocytes, increase the cell nuclear Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.05), and decrease Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.05), and showed a certain dose-effect relationship.
CONCLUSIONThe vinegar processing can further reduce the toxicity of Euphorbia Pekinensis Radix on enterocytes. Its possible mechanism can decrease the effect of Euphorbia Pekinensis Radix on the permeability of IEC-6 cell membrane, so as to provide a basis for further explanation of the detoxication mechanism of Euphorbia Pekinensis Radix processed with vinegar.
