The high mortality of paraquat (PQ) poisonings is mainly due to the lack of effective treatments. The optimal method of extracorporeal removal of paraquat is often a matter of debate. Due to the lack of well-designed studies, we are often left with circumstantial evidence, and we must exercise our best clinical judgment as to whether extracorporeal paraquat removal is beneficial and if so, by what method. It is clear, however, that rapidity in paraquat removal is beneficial. Due to the urgent nature of treatment for paraquat poisoning, there may never be well-designed evidence-based studies to help guide us. In the meantime, we must continue to use less than ideal evidence and our own experience to guide our decision-making process. Most toxicologists recommend rapid initiation of charcoal haemoperfusion (CHP) to lower plasma PQ levels and to limit pulmonary and other organs uptake of PQ.

Aim To study the effect of (S) -1, 8-(2-methyl phosphate ethoxy )-6-fluorine-7-( 4-methyl- pi-perazine-1-base )-3-[ S-benzyls-based-4-( for nitroben-zene methylene group amino )-1 , 2 , 4-all triazole-3 base]-quinoline ( 1-H )-4-ketone ( M18 ) on apoptosis of hepatocarcinoma SMMC-7721 cells in vitro. Meth-ods With different concentrations of M18 at different time used to treat SMMC-7721 cells, human breast cancer MB-231cells, human colon cancer HCT-116 cells, human hepatocarcinoma HEPG-2 cells, mouse bone marrow mesenchymal stem cells ( BMSCs ) in vitro,the inhibition effects of M18 on cell proliferation were examined by MTT assay. Cell apoptosis was de-termined using Hoechst 33258 fluorescence staining and TUNEL method. Mitochondrial membrane poten-tial (△ψm ) was measured using a high content screening image system. Protein expression of caspase-3 , p53 and cytochrome C was detected with Western blot analysis. Results Treatment with M18 ( 4 ~32μmol·L-1 ) potently inhibited the proliferation of the cancer cells in time-and dose-dependent manners ( the IC50 value at 24 h in SMMC-7721 cells, MB-231cells,
HCT-116 cells and HEPG-2 cells was 8. 65 μmol · L-1 , 9. 37 μmol · L-1 , 12. 74 μmol · L-1 and 9. 40μmol · L-1 , respectively ) . In contrast, M18 had weak cytotoxicity against BMSCs with IC50 value of 38. 96 μmol·L-1 . Levofloxacin had weak cytotoxicity against SMMC-7721 cells with IC50 value of 735. 10μmol·L-1 . Treatment of SMMC-7721cells with differ-ent concentrations of M18 for 24 h increased the per-centage of the apoptosis cells ( P <0. 05 ) and de-creased the mitochondrial membrane potential. In ad-dition, M18 increased protein expression of p53, caspase-3 and the cleaved activated forms of caspase-3 in SMMC-7721 cells. Treatment of SMMC-7721 cells with M18 significantly increased cytochrome C in the cytosol, and decreased cytochrome C in the mitochon-drial compartment. Conclusion The mitochondrial-dependent pathways are involved in M18 induction of apoptosis of SMMC-7721 cells.

BACKGROUND:Clinical infusion of hematopoietic stem cells and mesenchymal stem cells for treatment of aplastic anemia has been reported. OBJECTIVE:To investigate the effect of human adipose-derived mesenchymal stems cells on the secretion function of T lymphocytes of aplastic anemia patients. METHODS:Human adipose-derived mesenchymal stems cells were extracted from healthy human adipose tissues. T-lymphocytes were harvested from peripheral blood of patients with aplastic anemia by density gradient centrifugation. Human adipose-derived mesenchymal stems cells were co-cultured with T-lymphocytes. The levels of interleukin-2, interleukin-4, interleukin-10 and interferon-γwere detected by enzyme linked immunosorbent assay. T-bet and GATA-3 levels were examined by real-time PCR and western blot. RESULTS AND CONCLUSION:The levels of Th1 type cytokines interferon-γand interleukin-2 in the co-culture group were significantly lower than those in the T-lymphocyte group (P<0.05). But the levels of Th2 type cytokines interleukin-4 and interleukin-10 in the co-culture group were significantly higher than those in the T-lymphocyte group (P<0.05). The T-bet mRNA and protein levels in the co-culture group were significantly lower than those in the T-lymphocyte group, while the GATA-3 mRNA and protein levels were significantly higher in the co-culture group. Human adipose-derived mesenchymal stems cells can mediate an immunoregulation effect on T-lymphocytes of aplastic anemia patients in vitro, which is possibly related with the inhibition of Th1-dominant response due to the disorder of T-bet and GATA-3 gene expression.
