RESUMEN
Objective To investigate influence of mirtazapine on polysomnograpy (PSG) of depression dysphylaxia patient and treatment effect.Methods 22 dysphylaxia patients and 22 healthy contrast persons were detected by PSG.The group of dysphylaxia patients were re-detected PSG 6 weeks later after treatment by Mirtazapine.In order to evaluate the patient' symptoms of depression and early awakening,the scale of HAMD was utilized at the time before and after 2 weeks,6 weeks treatment by mirtazapine.To compare changes of PSG index,HAMD scores and dysphylaxia scores before and after treatment.Results Compared with healthy controls,there existed much deviation with dysphylaxia patients on PSG index.6 weeks after mirtazapine treatment,the PSG showed the sleeping latency had shortened to ( 16.9 ± 6.6) min,sleep efficiency had improved ( 85.4 ± 6.7 ) ％,awake time had shortened (27.7 ± 10.4)min,sleep maintenance rate had risen (87.9 ±5.3)％,decrease (9.7±4.1 )％ of the S1 sleeping stage percentage,S2 had increased ( 148.0 ±30.7)％,REM density had decreased (56.1 ±3.8)％.the difference was significant (P＜0.05).The scores of HAMD and early awakening after treatment were significantly lower than before treatment,the difference was significant (P＜0.01 ).Correlation analysis showed there was no significant correlation between the HAMD,dysphylaxia reduced rate and changes of PSG all indicators(P ＞ 0.05 ).Conclusion It may be one of the biological markers for dysphylaxi in shortened of REM sleep latency,prolonged of REM sleep time and increased of REM activity and density.There is no correlation between post-treatment changes of PSG.
RESUMEN
Objective Study the special value of the brainstem auditory evoked potential(BAEP)and Brain Geography Diagram(BEAM/EEG)for diagnosis of Newborn HypoxicIschemic Encephalopathy(HIE),the correlation between BAEP,BEAM/EEG and HIG,and the relation with HIE linger effect,so as to evaluate clinical curative effect,find out the best treatment time,lower the occurrence of linger effect.Methods the BEAM/EEG and BAEP were detected synehronously by adopting 16 traots of BEAM/EEG and BAEP instruments for HIE before treatment,at thirtieth day,the third Month,the sixth Month,the twelfth Month and the twenty-fourth Month respectively.Results The BAEP,BEAM/EEG have special diagnostic value on nerve cell function recovery,examination of recovery period in particalar.The research discovers the both are not synehronous in recovery period,the BAEP recovers is later than BEAM/EEG;for heavy degree HIE,BAEP recovering is slow with bad therapy effect,BAEP index sign is more sensitive to BEAM/EEG to assess linger effect.Conclusions Simple BEAM/EEG damaye indicates the brain cortex iniury only,so the prognosis is good;while BAEP damage suggestes the patiemts have brain stem nerve cell injury simultaneously,with bad prognosis for the heavy degree abnormality.in combination with BAEP and BEAM/EEG in clinical practiae,investigation of recovery degree of HIE herve cells by kinds of electric physiology angles it would have important value to perfect the treatment of HIE.
