Objective:To implore the effect of continuous positive airway pressure (CPAP) therapy on dizziness patients and its mechanism. Method:Seventy-five dizziness patients were enrolled. All patients accepted polysomnographic test, dizziness handicap inventory, Pitsburgh sleep quality index and Epworth sleepiness scale before and after CPAP therapy. Patients were divided into two groups according to a polysomnographic test: OSAHS group (AHI≥15) and without OSAHS group (AHI<15); divided into three groups according to dizziness handicap inventory score: mild dizziness group (0P<0.01). ②The effectiveness of CPAP therapy between OSAHS group and without OSAHS group has no difference (P>0.05), but CPAP therapy could ameliorate sleep disorder of the OSAHS group. ③Different levels of dizziness had no impact on improving DHI during CPAP therapy. However, the effect on sleep improvement decreased when patients had heavier dizziness. ④Treating by CPAP after three months could significantly improve patients dizziness (P<0.01). ⑤The dizziness of the patients in younger old group and old group have significant improvement after CPAP therapy (P<0.01). However, only younger old group has better sleep. Conclusion:CPAP therapy could dramatically improve dizziness in patients with sleep disorders.

Colorectal cancer is a kind of malignancies with high incidence in the worldwide, that is seriously harmed human health. So far the pathogenesis of the disease is not fully understood, this causing many difficulties to the diagnosis and treatment of the disease, and resulting in the cure rates of disease is not ideal. With the development of molecular genetics and molecular biology, many oncogenes and tumor suppressor genes have been found to be associated with the disease, and this made it is possible to reveal the pathogenesis of colorectal cancer at the molecular level. However, it is a complex and multi-step process from normal colorectal epithelial cells transformed to colorectal cancer cells, and it is the results of polygenic and multifactorial interactions. Now it is thought that the Wnt, TGF-beta, PI3K/Akt, MAPK and p53 signaling pathways are closely associated with pathogenesis of colorectal cancer. Based on the five kinds of signaling pathways as the main line, this article reviewed the roles of different signaling pathways and their related genes in the pathogenesis of colorectal cancer.
