Several signaling pathways are involved in clonal proliferation of lymphoma cells and disease progression. It has been shown that cyclic adenosine monophosphate (cAMP) signaling pathway, as an important intra-cellular messenger delivery system, is related to modulation of multiple physiological processes including cell prolifer-ation, secretion, metabolism and apoptosis. Manipulating the cAMP signaling pathway can induce cell cycle arrest and apoptosis of various malignant lymphoid cells, which involves mitochondria-dependent apoptosis and cAMP-modulated protein kinases as well as changes of intracellular mediators. In-depth research and analysis of cAMP-induced apoptosis in lymphoma cells would provide potential targets and possible therapeutic means for the treatment of lymphoma.

Objective: To explore and discuss the clinical curative effect on intermittent positive pressure breathing therapy of non - invasive ventilator in the treatment for chronic obstructive pulmonary disease (COPD) of elderly patients with complication of acute respiratory failure. Methods: 112 elderly patients who were COPD (all of patients were acute exacerbation period) with complication of acute respiratory failure were divided into control group (60 cases) and observation group (52 cases) as the random number table. A series of basic therapy including routine anti-inflammatory, relieving asthma and expectorant therapy were implemented for all of patient. And the non-invasive ventilator was used to implement non-invasive mechanical breathing therapy. In this therapy, patients of control group were implemented sustaining positive pressure breathing therapy, while patients of observation group were implement intermittent non-invasive positive pressure breathing therapy (1:1). The curative effect, pH value (at 6,24 and 72h), PaO2 (at 6,24 and 72h), PaCO2 (at 6,24 and 72h) and complications between the two methods were compared. Results: There was no significant difference in the general demographic characteristics between the two groups. For patients at 6, 24 and 72 h, the differences of the pH value, PaO2and PaCO2 between pre and post-treatment were significant in observation group (F=5.669, F=6.985, F=7.628, P<0.05) and control group (F=5.311, F=6.892, F=7.958, P<0.05) , respectively. The differences of the pH value, PaO2 and PaCO2 at 6h, 24h and 72h were significant (at 24h, F=6.776, F=7.098, F=7.673. at 72 h, F=7.883, F=6.983, F=7.335, P<0.05),respectively. For two groups, the differences of pH value, PaO2 and PaCO2 at pre-weaning, post-weaning 6h and post-weaning 12h were not significant. While the mechanical ventilation time and mechanical ventilation rate of observation group were significant lower than that of control group (t=3.591, x2=3.052, P<0.05). Besides, the incidences of complications including flatulence, trachea intubation, respiratory and relative pneumonia of observation group were significant lower than that of control group (x2=4.997, P<0.05). Conclusion: The new method can significantly shorten duration of breathing and duration of hospital stays. And its incidence of complication is lower while safety of treatment is relatively higher than that of traditional method.
