Abstract:
Objective To analysis the effect of caffeine citrate on pulmonary function, vascular endothelial growth factor (VEGF)and insulin like growth factor -1 (IGF-1) in the apnea syndrome rats.Methods 80 male Wistar rats were selected, 20 were randomly selected to be the control group, the rest of the rats were replicated of apnea syndrome model.The rats were randomly divided into model group, experiment group and positive drug group, 20 of each group.The experimental group was given caffeine citrate injection of 5 mg/kg intraperitoneal injection, the positive drug group was given intraperitoneal injection of aminophylline 3 mg/kg, the model group was given intraperitoneal injection of normal saline, once a day, continuously for 1 week.Pulmonary function, serum VEGF, IGF-1 levels and sleep apnea were compared after the experiment.ResuIts Compared with the positive drug group, the related indexes of pulmonary function of the experimental group increased significantly ( P<0.05 ) .Serum VEGF levels decreased significantly (P<0.05).The serum IGF-1 level increased significantly (P<0.05).The sleep apnea index decreased significantly during the period of NREM and REM.(P<0.05).ConcIusion Caffeine citrate can improve apnea syndrome rats lung function, reduce the serum VEGF level, promote the formation of serum IGF-1, reduce the sleep apnea index.
