ObjectiveTo study the protective effects of Qiqiong(QQJN) on focal cerebral ischemia/reperfusion injury and its mechanism. MethodsMiddle cerebral artery occlusion(MCAO) was used to make focal cerebral ischemia/reperfusion model by intravascular nylon filament occlusion. The protective effects of QQJN were evaluated by investigating neurological function score, percentage of cerebral infarction, pathomorphology of brain, the activity of SOD and the content of MDA in hrain tissue,thrombogenesis and platelet aggregation in vitro. ResultsCompared with model group, QQJN(4.4、8.8g/kg)could decrease the neurological score in 8 and 22h after reperfusion, reduce the percentage of cerebral infauction,improve pathomorphology of brain, decrease the length, wet weight and dry weight of thromb and inhibit platelet aggregation. ConclusionQQJN had protective effects on focal cerebral ischemia/reperfusion injury. The role of anti-injury of free radicals,inhibit thrombogenesis and platelet aggregation should contribute to its neuroprotective effects.

Objective To explore the method for differentiation induction of leukemia cells into dendritic cells(DC) by A23187 in vitro. Methods Chronic myeloid leukemia K562 cells were cultured with A23187 or cytokine to induce differentiation and form DC. The morphologic features of cells were observed under inverted microscope, the changes of DC surface marks were determined by flow cytometry and RT-PCR, the ability to stimulate lymphocyte proliferation was tested by MTT colorimetry. Results Under the condition of the does (385 ng/ml) of A23187 for four days, some of K562 cells were found in typical dendritic appearance.The expression of DC markers CD1a,CD83 ,HLA-DR,CD86 and CD80 was 6.65 ±2.70,7.37 ±2.40,6.24 ±4.29, 21.60 ± 3.84, 18.52 ± 4.48 repectively, and increased obviously compared with the negative control group(2.80 ±0.52,1.85 ±0.56,2.25 ±0.47,6.69 ±0.83,9.96 ±3.53). The differences had statistical significance (P < 0.05). K562 cells derived from DC acquired the ability to stimulate lymphocyte proliferation.Conclusion A23187 can induce the leukemia cells differenntiation into activated DC-like cells rapidly.
