High mobility group box-1(HMGB1)distributed widely.It exists in many organs.HMGB1 locates in nuclei and cytoplasm in normal condition.It involves in many activity of life(i.e.,duplication of DNA,cellular differentiation,gene expression).The immunocytes(i.e.,mononuclear macrophage and dendritic cells)secrete HMGB1 into the extracellular milieu when stimulated with LPS and cytokines.It acts as proinflammatory cytokines,activates inflammatory and immunological responses.As a late mediators of inflammation and last long,HMGB1 plays an important role in sepsis,so it may be a convenient and practical index in evaluating severity of sepsis and may be an important and new therapeutic target in sepsis.It has been initially proved in experimental and clinical study.

Objective To study effects ofDanlong Xingnao Formula (DLXNF) on proliferation of neural stem cells (NSCs) and the expressions of Hes1 and Hes5 in sub ventricular zone (SVZ) in cerebral ischemia-reperfusion injury model rats; To explore the mechanism of promoting the proliferation of NSCsMethods Eighty male SD rats were randomly divided into sham-operation group, model group, edaravone group andDLXNF group. The focal cerebral ischemia reperfusion injury models were prepared by suture method, and 7 d after reperfusion, the SVZ brain tissue of ischemia side was taken. The proliferation of cells was detected by Brdu labeling fluorescence immunocytochemistry; Hes1, Hes5 mRNA and protein expressions were detected by fluorescence real-time quantitative PCR and Western blot method in each group.Results Compared with the sham-operation group, Brdu positive cell rate in other groups increased more obviously, and the expressions of Hes1, Hes5 mRNA and protein also increased significantly (P<0.01). Compared with the model group, Brdu positive cell rate increased significantly in edaravone group and DLXNF group, and the expressions of Hes1, Hes5 mRNA and protein increased significantly (P<0.01). The expression of Hes1 mRNA in DLXNF group was superior to that in edaravone group (P<0.01), and other indexes had no significant difference.Conclusion DLXNF can promote the proliferation of NSCs in SVZ in cerebral ischemia-reperfusion injury model rats, and up-regulate the expressions of Hes1 and Hes5, whose mechanism may be related to the activation of Notch signaling pathway.

Objective To study the relationship of proliferation of neural stem cells (NSCs) in SVZ and the expressions of c-jun and c-myc in rats with middle cerebral artery occlusion/reperfusion (MCAO/R) injury model administrated byDanlong XingnaoFormula.Methods The focal cerebral ischemia reperfusion injury models were prepared by longa method. Totally 150 male SD rats were randomly divided into sham-operation group, cerebral model group,Danlong XingnaoFormula low-, medium-, and high-dose groups. The treatment groups were given corresponding dose ofDanlong XingnaoFormula, while the sham-operation group and model group were given the same amount of distilled water 24 h after modeling by gavage, once a day, 7 days in a row. 1 d, 3 d and 7 d after reperfusion, modified Neurological Severity Scores (m-NSS) was used to grade neurologic impairment. 7 d after reperfusion taken to the SVZ brain tissue of ischemia side, Brdu immunohistochemical method was used to record the BrdU positive cells number. The hippocampal c-jun, c-myc mRNA and protein expressions were determined respectively by RT-qPCR method and Western blot method.Results Grades of neurologic impairment in others groups were improved obviously than sham-operation group (P<0.01); 3 d, and 7 d after reperfusion, grades of neurologic impairment inDanlong XingnaoFormula groups were obviously lower compared with model group (P<0.05,P<0.01). Brdu positive cell rates in others groups increased obviously compared with sham-operation group; Compared with model group, Brdu positive cell rates inDanlong XingnaoFormula groups increased obviously (P<0.01). The expressions of c-jun and c-myc protein and mRNA inDanlong XingnaoFormula groups improved obviously than sham-operation group and model group (P<0.01).ConclusionDanlong Xingnao Formula can improve the neural function after cerebral ischemia and stimulate the proliferation of NSCs, and the mechanism may be related to activating the expression of c-jun and c-myc and extending the duration.
