Objective To investigate the protective effects and mechanisms of NF-KB inhibitor pyrrolidine dithiocarbamate (PDTC) on infant rabbits with lung injury caused by mechanical ventilation. Methods Twenty healthy infant rabbits were randomly divided into four groups. (1) Mechanical ventilation (MV, with VT = 24 ml/kg);(2) Mechanical ventilation plus PDTC pre-treatment (MVP, VT = 24 ml/kg with PDTC 100 mg/kg injection via ear vein half an hour prior to MV) ; (3) Mechanical ventilation combined with endotoxin (EMV, 0.1 ml/kg of endotoxin dripping into trachea then on MV, VT = 24 ml/kg) ; (4) EMV plus PDTC pretreatment (EMVP, PDTC 100 mg/kg injection via ear vein followed by 0.1 mg/kg of endotoxin dripping into trachea in half an hour then on MV with VT = 24 ml/kg for 4 h continuously. MPO and the activation of NF-κB in lung tissues and the genetic expression and protein quantity of TNF-α and IL-8 in homogenate were measured. The pathological changes in lung tissues were examined. Results Pre-treatment with PDTC had significant minor pathological changes caused by MV and MV plus endotoxin, which were indicated by the fact that MPO, activation of NF-KB and the genetic expression and protein quantity of TNF-α and IL-8 were significantly suppressed. Conclusions PDTC could decrease the expression, synthesis and release of pro-inflammatory cytokines. This may be through suppressing the activation of NF-κB resulting in less infiltration with inflammatory cells and protective effects on lung injury caused by MV and MV plus endotoxin.

Objective To expore the mechanism of low-dose interfone-γ(IFN-γ) influences on differentiation of oligodendrocyte precursor cell. Methods The cerebral cortex samples were obtained from one day old SD rats to form mixed single cell suspensions. After culturing in full medium for 7 to 10 days, succession and differential velocity adherent technique were performed to acquire oligodendrocyte precursor cell and cultured in serum-free medium. IFN-γ, AG490 and Fludarabine were added during the culture of oligodendrocyte precursor cell and reverse transcription-polymerase chain reaction, Western blot and flow cytometry were performed to evaluate the expression of intracellular P27kip1 and its influence on the differentiation of oligodendrocyte precursor cell. Results (1)The expression of P27kip1 mRNA and protein was lower in IFN-γ group than in control group (t=85. 535, P<0. 05;t= 12. 481, P<0. 05), while the expression of P27kip1 mRNA and protein in IFN-γ+AG490 group and IFN-γ+Fludarabine group were both higher than those in IFN-γ group (P<0. 05). (2) The phosphorylation levels of JAK2/STAT1 in INF-γ group were higher than that in the other three groups (P<0. 05). (3) The percentage of myelin basic protein positive cells was (68. 42 ± 2. 53)% in IFN-γ group, lower than that in control group [(88.21 ± 1.97)%](t=10.682, P < 0.05). Myelin basic protein positive cells in IFN-γ + AG490 group were (57. 63 ±2. 75) %, lower than those in the IFN-γ group. The same figure in IFN-γ+Fludarabine group were (79. 53±4. 15)% , higher than those in IFN-γ group (t = 3.957, P<0.05). Conclusions Low-dose IFN-γ can regulate the expression of intracellular P27kip1 through JAK2/STAT1 signal transduction pathway and Fludarabine may participate in this process and improve the differentiation and maturation of oligodendrocyte precursor cell.

Objective To investigate the Toxoplasma gondii infection status in pregnant women with history of adverse preg?nancy and risk factors in Bazhou area,Hebei Province. Methods A total of 302 pregnant women with the history of adverse pregnancy were chosen as respondents(an experimental group)in the hospital from March 2012 to December 2015,and 197 pregnant women without the history of adverse pregnancy as a control group. TOX?IgG and TOX?IgM were detected by using ELI?SA in two groups. The risk factors of Toxoplasma infection were surveyed by questionnaires. Results The total positive rate of Toxoplasma antibodies was 28.15%(85/302)in the experimental group,which was significantly higher than that[9.64%(19/197)]in the control group,and the difference was statistically significant(χ2=24.76,P<0.05). The positive rates of TOX?IgM,TOX?IgG and TOX?IgM+TOX?IgG were 6.95%(21/302),18.54%(56/302),and 2.65%(8/302)respectively in the ex?perimental group,which were higher than 2.03%(4/197),7.61%(15/197),and 0%(0/197)respectively in the control group (χ2=6.07,11.67,3.76,all P<0.05). The questionnaire survey showed that the proportions of keeping pets,cutting board re?gardless,liking to eat hot pot or barbecue,eating raw meat,often eating in the restaurant in the pregnant women with Toxoplas?ma infection were higher than those in the pregnant women without Toxoplasma infection,and the differences were statistically significant(χ2=22.57,3.96,5.87,7.40,4.86,all P<0.05),and therefore,the above unhealthy habits may be important risk factors. Conclusions Toxoplasma infection could lead to adverse pregnancy outcomes. Therefore,the above?mentioned unhealthy habits should be avoided,especially during pregnancy period.
