Background The severity of difficulty in falling asleep and the insufficiency of the sleeping time in the primary insomniacs always were overestimated, even after medication and improving the objective sleep quality. Moreover, remarkable psychosomatic symptoms were found in patients and the symptoms were significantly linked to the self-reported sleep quality. So in this study, it was designed to explore the differences between objective and subjective sleep quality and its correlative factors in chronic insomniacs.Methods A total of 55 chronic primary insomniac cases diagnosed by DSM-Ⅳ diagnostic criteria for primary insomnia and 15 normal controls were rated with Pittsburgh sleep quality index (PSQI),State-Trait Anxiety Inventory (STAI), and the Subjective General Condition Form. All cases and the controls were then examined by the whole-night polysomnography (PSG) records.Results Compared with the objective parameters of PSG, the subjective parametersiu chronic insomniacs had significantly longer sleep latency and lower total sleep time and sleep efficiency [ (80. 3± 73.7)min v.s. (23.2 ± 25.4) min, (157.8±141.7)min v.s. (332.2±154.7)min , (0.52 ±0. 27) min v.s. (0. 67 ± 0. 28) min, respectively, P ＜0. 001 ]. The difference between subjective and objective sleep latency was related to the total scores of STAI, TAI and SAI ( r = 0. 402,0. 374 and 0. 397, respectively, P ＜ 0. 05).Conclusions There were significant differences between objective and subjective estimations of sleep quality in chronic insomniacs,and they might result in the overestimation of the severity of insomnia. The differences between subjective and objective sleep quality in the chronic insomniacs were significantly correlated with the levels of anxiety.

Objective To investigate nasomaxlllary complex facial soft tissue changes after the treatment with maxillary protraction appliance with skeletal Class Ⅲ malocclusion with a retruded maxilla.Methods Thirty growing subjects with skeletal Class Ⅲ malocclusions with maxillary retrognathism were selected and treated by facial mask(male 15,female 15,with an average age of 10.5).They were given a maxillary protraction treatment with face mask for 6-8 months.Cephalometric measurements about nasomaxillary complex soft tissue changes were analyzed to draw the statistic conclusion.Results After maxillary protraction treatment,PraY,nasofrontal angle,As-Y,UL-Y,UL-E,S-Ns-Sn increased (P ＜ 0.01) ; M-Y increased (P ＜ 0.05) ; LL-E,PosY,nasolabial angle decreased (P ＜ 0.05).There were no significant differences in the Ns-Y and columella-tip angle.Conclusion After maxillary protraction treatment,nasomaxillary complex area becomes more marked.Both the nasomaxillary complex soft tissue and lower facial profile are dramatically improved.The combining effect of these two changes results in a more harmony profile.
