Abstract
REM-sleep Behavior Disorder (RBD) is a parasomnia which is characterized by dream-enacting behavior due to loss of normalrnskeletal muscle atonia during sleep. RBD can lead to a neurodegenerative disorder such as Parkinson disease, MSA or DLB inrn81% after 16 years. Therefore, an early diagnosis of RBD is important. Video-Polysomnography (V-PSG) is required to confirmrnthe diagnosis of RBD, which is obviously unsuitable for screening purposes. Studies using the SLEEP-EVAL system and the MayornSleep Questionnaire suggested a prevalence of RBD between 0.5 to 8.9%. Both questionnaires have poor or unknown specificity.rnRecently the ‘REM Sleep Behavior Disorder Screening Questionnaire’ (RBDSQ) has been validated with a sensitivity of 0.96 andrna specificity of up to 0.92 underlining its potential usefulness as a screening instrument. The objective of this research project wasrnto investigate the prevalence of RBD by the RBDSQ in non-neurological patients. Between October 2008 and October 2010 thernRBDSQ was administered to 551 subjects in the out-patient setting of GP practices and the in-patient setting of non-neurologicalrnwards. This screening revealed a prevalence of 27%, clearly exceeding previously known data. Accordingly, after performing arnV-PSG in five participants we confirmed only one case of RBD and another case with possible RBD. The present work suggestsrnthat results of the RBDSQ and probably also other questionnaires have to be interpreted with caution. Its usefulness as a screeningrninstrument needs further investigation and refinement.

Abstract
Objective: To observe the changes of CD4+CD25+FoxP3 and IL-2, IL-6, IL-10, TNF-α inflammatory factors in the peripheralrnblood of the early PD patients and to further explore the correlations about CD4+CD25+FoxP3 and IL-2, IL-6, IL-10, TNF-αrninflammatory factors in peripheral blood of the early PD patients whether the level of CD4+CD25+FoxP3 and IL-2, IL-6, IL-10,rnTNF-αin different years, sex, grade and depression or not is different.rnMethods: CD4+CD25+FoxP3 were measured in 15 PD patients by the direct immunofluroscent staining technique and whichrnrelated inflammatory factors were measured by ELISA and compared with 30 normal controls.rnResults: The levels of CD4+CD25+FoxP3 in PD were depressed as compared with healthy controls (p<0.01). The levels of IL-2,rnIL-6, IL-10 and TNF-α in PD were higher than healthy controls (p<0.05). Different ages, different grade, presence or absencernof depression among PD patients, peripheral blood CD4+CD25+FoxP3 and which related inflammatory factors were notrnsignificantly different (p>0.05). IL-10 was significantly different between men and women in the PD group, the female level ofrnIL-10 was higher than the male (p<0.05), CD4+CD25+FoxP3 and the rest of the inflammatory factors were not different (p>0.05),rnthe changes of CD4+CD25+FoxP3, IL-2, IL-6, IL-10 and TNF-α in peripheral blood were in no significant correlation comparedrnwith age, sex, grade and depression.rnConclusion: CD4+CD25+FoxP3 immune functional decline and imbalance of IL-2, IL-6, IL-10 and TNF-α inflammatoryrnfactor were observed in early PD patients. The cellular immune function in patients was no significant among different ages,rndifferent classification and depressive symptoms or not but the level of IL-10 exists difference between male and female groups,rnCD4+CD25+FoxP3 and IL-2, IL-6, IL-10, TNF-α may be involved in the pathogenesis of early Parkinson’s disease in thernpathophysiology and pathogenesis of PD has played a certain role.
