Objective To investigate the correlation between the expression of redox factor-1 (Ref-1) and neuronal apoptosis around hematoma after experimental intracerebral hemorrhage (ICH) in rats.Methods ICH model of rat was induced using stereotactic infusion antilogous blood 50 ?l into the caudate nucleus. The male animals were randomly divided into sham operation group, normal control group and hemorrhage group. TUNEL and immunohistochemistry methods were used to detect apoptosis and the expression of Ref-1 in cerebral tissues at different time, respectively.Results The expression of Ref-1 was negatively correlated with neuronal apoptosis around hematoma after ICH (r=-0.745, P

Objective To evaluate the alteration of CD4+ regulatory T cells in peripheral blood from patients with ankylosing spondylitis(AS). Methods Seventy-eight AS patients and 50 healthy individuals were included in this study. The proportion of CD4+CD25+CD127lo/- T cell population in CD4+ T cells as well as that cytotoxic T lymphocytes(CTL) and NK cells in lymphocytes was evaluated by flow cytometry. Serum TGF-β and TNF-α were measured by ELISA. The inhibitory function of CD4+CD25+ regulatory T cells was measured by mixed lymphocyte culture. Results The population of CD4+CD25+CD127lo/- T cells in peripheral blood of AS patients accounted for (4.36±1.21)% of CD4+ T lymphocytes, which was significantly lower than that in healthy individuals (P<0.05). The CD4+CD25+CD127lo/- T cells population in AS patients was positively correlated with TGF-β level, but negatively with TNF-α. Compared with healthy individuals, the function of CD4+CD25+ regulatory T cells in the inhibition of alloreactive T cells was lower in AS patients, which was related to the decreased secretion of TGF-β. Conclusion The CD4+ regulatory T cells in peripheral blood of AS patients are significantly decreased and its function is defective, which leads to immune regulatory dysfunction in vivo. It may be one of immune pathogenesis mechanisms of AS.

Objective To evaluate the effect of alprostadil on acute lung injury in septic rats. Methods Thirty adult male Sprague?Dawley rats, weighing 200-250 g, were randomly divided into 3 groups (n=10 each) using a random number table: sham operation group (group S), acute lung injury group ( group ALI) , and alprostadil group ( group Q) . The animals were anesthetized with intraperitoneal 1% pentobarbital sodium 5 ml∕100 g. Sepsis was induced by cecal ligation and puncture. In group Q, al?prostadil ( 10 μg∕2 ml) 2 ml∕kg was injected via the tail vein at 30 min before cecal ligation and puncture. The equal volume of normal saline was given in S and ALI groups. At 24 h after operation, blood samples were taken for determination of serum tumor necrosis factor?alpha ( TNF?α) and interleukin?6 ( IL?6) con?centrations by enzyme?linked immunosorbent assay. The animals were then sacrificed. The left lungs were immediately removed for microscopic examination, and the right lungs were immediately removed for deter?mination of wet∕dry lung weight ratio ( W∕D ratio ) , and expression of TNF?α mRNA and high mobility group box?1 ( HMGB1) using real?time reverse transcriptase?polymerase chain reaction. Results Com?pared with group S, the concentrations of serum TNF?α and IL?6 were significantly increased, and the ex?pression of TNF?α mRNA and HMGB1 mRNA was up?regulated, and W∕D ratio was increased in ALI and Q groups ( P<0?05) . Compared with group ALI, the concentrations of serum TNF?αand IL?6 were signifi? cantly decreased, and the expression of TNF?α mRNA and HMGB1 mRNA was down?regulated, and W∕D ratio was decreased in group Q ( P<0?05) . The pathological changes of left lungs were significantly attenua?ted in group Q as compared with group ALI. Conclusion Alprostadil can reduce acute lung injury in septic rats, and the mechanism may be related to down?regulation of HMGB1 expression and inhibition of inflam?matory responses.

Objective:To study the molecular mechanism for momordin in inducing apoptosis of multidrug-resistant human chronic leukemia K562/A02 cells. Methods:The growth inhibition value of K562/A02 cells was detected by CCK-8 method. Cell apoptosis was analyzed by Annexin Ⅴ flow cytometry (FCM) and cell morphological examination. FCM was also used in determining expression of P-glycoprotein, p53 protein, bcl-2 protein and caspase activity. Results:Momordin inhibited the proliferation of K562/A02 cells in a dose-dependent manner. It also induced cell apoptosis, reduced the expression of P-glycoprotein, p53 protein and bcl-2 protein, and increased caspase-3 and caspase-8 activity.Conclusion:Momordin reversed the inhibition of apoptosis in multidrug-resistant K562/A02 cells. The molecular mechanism may be related with down-regulation of expression of p53 protein, P-glycoprotein, and bcl-2 protein and up-regulation of caspase-3 and caspase-8 activities.
