The NF-kappaB pathway regulates the expression of over 150 target genes, e.g., cytokines, chemokines, leukocyte adhesion molecules and inducible effector enzymes. Consequently, it plays a crucial role in innate and adaptive immune responses, inflammatory response, stress responses, apoptosis and so on. IkappaB kinase (IKK) is the key of this pathway, and it owns a special structure which consists of catalytic subunit and regulatory subunit. Naturally, the activation of IKK needs the interaction of the two subunits and phosphorylation by its upstream kinases. Actually, there are two methods of activation of the NF-kappaB pathway, and both of the methods need the IKK complex. Given to the crucial role of IKK, researchers have isolated and synthesized amounts of IKK inhibitors, and these provide a great convenience to develop novel anti-inflammatory and anti-tumor drugs.

Objective To observe the effect of early non-invasive positive pressure ventilation(NIPPV)on the treatment of serious hypoxemia induced by acute left heart failure. Methods Forty patients with acute left heart failure( Grade Ⅳ heart function)were randomly divided into two groups. Patients in both groups accepted supportive treatment included cardiotonics, diuretics, vasodilators, in additional to these high concentrations of oxygen were given in conventional group, and non-invasive positive pressure ventilation were given in NIPPV group by biphasic positive airway pressure(BiPAP). Systolic blood pressure, heart rate, respiratory rate, blood-gas analysis( pH, PaO2, PaCO2, SaO2 )and clinical signs were observed at 2 hours after treatments. Results Compared to control,RR( [ 19.55 ± 1.88] vs [21.85 ±3.51 ] ) BPM] ,HR ( [96.40 ±2.80] vs[ 103.20 ±6.78 ] BPM), SBP ( [ 116.30 ± 8.95 ] mm Hg vs [ 122.50 ± 6.13 ] mm Hg), pH (7.404 ± 0.027 vs 7.358 ±0.05) ,SaO2 ( [93.57 ± 1.18]% vs [91.97 ± 1.85]% ) ,PaO2 ( [75.58 ±4.61 ]mm Hg vs [68.38 ±7.95]mm Hg), PaCO2 ( [ 38.69 ± 3.06 ] mm Hg vs [ 43.61 ± 2.65 ] mmHg) were significantly different in NIPPV group( t = 2.582,4.146,2.558,3.534,3.256,3.505,5.428, Ps ＜ 0.05 ). We found no significant differences in the comparisons before treatments. Hypoxia improved in NIPPV group,and the total effective rate was 95% in NIPPV group and 70% in control group,which showed significant difference( x2 =4.329 ,P ＜0.05 ) Conclusion BiPAP non-invasive positive pressure ventilation combined with routine treatment in treating heart failure, could promptly correct hypoxia, improve heart function and shortening disease course.
