Objective To preliminarily analyze the credibility and validity of Chinese Medical Constitution Questionnaire(CMCQ).Methods CMCQ was used to investigate the distribution of Chinese medical constitution types of 450 women inpatients with postoperative nausea and vomiting (PONV) after gynecologic laparoscopic surgery from March to October of 2013.Credibility and validity were analyzed by Cronbach's α coefficient and factor analysis.Results Mixed constitution was identified in 184 (40.9％) patients.Cronbach's α coefficient of two dimensions (yang deficiency and qi stagnation) of CMCQ was proper,being 0.815 and 0.803 respectirely,while that of the dimension of harmony type was the lowest (0.514).The total variance explained by 9 common factors extracted from the results of factor analysis was only 48.5％.Conclusion CMCQ may need further revision based on the results of clinical application.

Objective To evaluate the Montreal cognitive assessment (MoCA) for detecting the mild cognitive impairment (MCI) in brain trauma patients with normal mini-mental state examination (MMSE) scores.Methods Fifty brain trauma patients with normal MMSE scores hospitalized from January 2013 to June 2014 were subjected to the MoCA test.The patients were classified as cognitive impairment group scored less than 26 on the MoCA and cognitive normal group scored 26 or above on the MoCA.Differences in MMSE and MoCA scores of the two groups were compared.Receiver operative characteristic (ROC) curve was used to determine the optimal cut-off scores in screening for MCI.Results Overall MMSE and MoCA scores were (27.84 ± 0.89) points and (23.24 ± 2.90) points.There was a positive correlation between MoCA and MMSE total scores (r =0.355 2,P ＜ 0.05).MCI was found in 79％ of the brain trauma patients using the MoCA.MMSE total score and subscores were all similar between the two groups.MoCA total score and subscores of attention,language,abstraction and delayed recall were much higher in cognitive normal group than in cognitive impairment group (P ＜0.05),but there were no significant differences in visuospatial,naming and oritention domains.Area under the ROC curve for MoCA(0.871 ± 0.038) was larger compared with MMSE (0.796 ± 0.054) (Z =3.592,P ＜ 0.05).The optimal cut-off scores of MoCA and MMSE for the identification of MCI were 25.5 and 28.5 respectively.Conclusions MoCA and MMSE total scores are positively correlated.MoCA is a better detector for the identification of MCI in brain trauma patients than the MMSE.

Delirium and cognitive impairment are common in the intensive care units (ICU). The Confusion Assessment Method Inten-sive Care Unit (CAM-ICU), Intensive Care Delirium Screening Checklist (ICDSC), Cognitive Test for Delirium (CTD), Nursing Delirium Scale (Nu-DESC) and Delirium Rating Scale (DRS) are recommended to assess delirium. CAM-ICU and ICDSC are the best in the reliabili-ty, validity, sensitivity and specification. Mini-Mental State Examination (MMSE), Abbreviated Mental Status Examination (AMSE), the Johns Hopkins Adapted Cognitive Exam are used commonly for cognitive impairment, and Johns Hopkins Adapted Cognitive Exam is one of the suitable scales for ICU as it is simple, comprehensive, and with higher reliability and validity.

Objective To investigate the clinical efficacy of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery for patients at the early stage of traumatic brain injury (TBI). Methods 72 patients with TBI hospitalized from January, 2013 to October, 2014 and 30 healthy controls matched gender, age and educational background were assessed with the Chinese version of LOTCA battery and Mini-Mental State Examination (MMSE) respectively. Results The score of MMSE and LOTCA were correlated (r=0.56, P<0.01). Compared with the controls, the scores of all the subtests of LOTCA decreased (P<0.01) in the patients, especially the orientation, visuomo-tor organization and thinking operation;with the more incidence of medium and serious dysfunction of all the subtests of LOTCA except perception (P<0.01), in which thinking operation was the most and attention was the least. The area under the receiver operating curve (ROC) was (0.84±0.04) in LOTCA, less than that of (0.91±0.03) in MMSE (P<0.05). Conclusion Cognition is widely impaired in patients after TBI, most involved thinking operation. LOTCA is less effective to identify cognitive dysfunction than MMSE, and can be used as an al-ternation or a supplement.

Objective To test the reliability and validity of the Chinese version of the John Hopkins Adapted Cognitive Exam ( ACE) in NICU patients. Methods The English ACE was translated and adapted into the Chinese version . Cognitive functions of 40 critically ill patients in NICU were assessed with the Chi?nese version of ACE and MMSE battery.The scores of ACE and MMSE were analyzed to test the content va?lidity,construct validity,concurrent validity,internal consistency,inter?rater reliability and test?retest reliabil?ity.Result The correlation coefficient between each factor and the total score ranged from 0.617 to 0.938, and the content validity was good.The ACE was significantly correlated with MMSE( r=0.822, P<0.05). Five factors were extracted by main principle analysis, the cumulative contribution was 85. 90%, the factor loading of each item was all over 0.5,the scale had good construct validity.There existed a good internal con?sistency ( Cronbach’ α=0.756 ) as well as a good inter?rater reliability ( ICC>0.95) and test?retest reliabil?ity (ICC=0.652?0.979) of the Chinese version of ACE.Conclusions The Chinese version of ACE has been proved to be a reliable and valid screening tool for cognitive impairment in NICU patients.

Objective To investigate the clinical validity of the Chinese version of John Hopkins Adapted Cognitive Exam (ACE) for in-patients in neurological intensive care unit (NICU). Methods From May, 2014 to June, 2015, 94 inpatients in NICU and 52 healthy persons were assessed with the Chinese version of ACE and Mini-Mental State Examination (MMSE). Results The total score of ACE correlated with the total score of MMSE (r=0.805, P<0.001). There was a significant difference in the total score and the scores of the subtests of both the ACE and MMSE between the patients and the controls (t>2.458, P<0.05). The area under the receiver operating curve was not different between ACE and MMSE (Z=0.707, P=0.480). Conclusion The Chinese version of ACE can be the tool for assessment of cognition for pa-tients in NICU.

Objective To investigate the clinical features of Parkinson disease (PD)with constipation.Methods From October 2013 to August 2015,a total of 204 PD patients were consecutively recruited from the Departments of Geriatrics and Neurology,Beijing Tiantan Hospital,Capital Medical University,and were evaluated by Rome Ⅲ diagnostic criteria for functional constipation and other related scales of motor symptoms(MS)and non-motor symptoms(NMS),the activity of daily living(ADL)and quality of life.Results Overall,131 of 204(64.2％)PD patients with constipation were assigned to the PD-C group and 73 of 204 (35.8％)PD patients without constipation were assigned to the PD-NC group.In the PD-C group,38 of 131(29％)PD patients had constipation before motor symptoms occurred.The mean age and age of onset in the PD-C group were significantly older than those in the PD-NC group (64.13 ± 9.67 vs.58.35 ± 11.37;60.07 ± 10.46 vs.55.10±12.97;F=2.287,4.948;t=3.827,-2.788;P＜0.01 for both).Meanwhile,compared with the PD-NC group,the PD-C group was associated with dramatically longer disease duration (2.25,range:1.00-5.00 vs.2.00,range:1.00-3.13;Z =-2.254;P ＜ 0.05),increased scores of the Unified Parkinson Disease Rating Scale (UPDRS) Ⅲ (26.00 scores,range:18.00 37.50 vs.19.00,range:12.50-31.00;Z =-2.349,P ＜ 0.05),more advanced stages on the Hoehn-Yahr (H-Y) scale (2.00 stage,range:1.50-2.50 vs.1.50,range:1.00-2.50;Z=-2.334,P＜0.05),higher total numbers of NMS(11.00,range:6.00-15.00 vs.6.00,range:3.00-11.00;Z=-3.715,P＜0.05),and higher numbers of NMS occurring before and after MS(before,2.00,range:0.00-4.00 vs.1.00,range:0.00-2.00;after,8.00,range:3.00-14.00 vs.5.00,range:2.00-9.50;Z =-2.612,-2.630,respectively;P＜0.05 for both).Additionally,there were significant differences between the groups in the scores of the Hamilton depression scale (HAMD),the Hamilton anxiety scale (HAMA),the Pittsburgh sleep quality index (PSQI),the scales for outcomes in Parkinson disease-autonomic (SCOPA-AUT),the Fatigue severity scale (FSS),the Apathy scale,the Montreal Cognitive Assessment(MoCA)scale,the UPDRS Ⅱ and ADL Scale,and the PDQL-39 (all P＜0.05).Binary Logistic regression analysis showed that age,SCOPA-AUT,HAMA and HAMD were risk factors for PD-C(OR=1.091,1.107,1.10 and 1.080;P＜0.05 for all).Conclusions PD patients have a high incidence of constipation,and more than a quarter of patients have constipation before MS occurs.Meanwhile,PD patients with constipation are usually associated with old age and late age of onset,long disease duration,severe MS,frequent and severe NMS,bad cognition,emotional state and sleep,severe fatigue,and apathy.Moreover,advanced age,autonomic dysfunction,anxiety and depression increase the risk of PD with constipation.Constipation has a serious negative impact on the activity of daily living and quality of life in PD patients.

Objective: To investigate the clinical characteristics of sleep disorders(SD)in patients with Alzheimer's disease(AD), and the relationship between SD and cognitive impairment. Methods: According to the inclusion and exclusion criteria of AD, 89 consecutive AD patients admitted to Beijing Tiantan Hospital from January 2016 to January 2017 were included.The Pittsburgh sleep quality index(PSQI)scale was used to evaluate the overall sleep status.The patients were randomized into the AD with SD(AD-SD)group(PSQI>7)and the AD without SD(AD-NSD)group(PSQI<7). The cognitive function of AD patients was evaluated by the Montreal cognitive assessment(MoCA)scale, and the overall cognitive function and cognitive domains were compared between the AD-SD and AD-NSD groups. Results: Of the 89 AD patients, 71 cases(79.78%)had SD.There was no significant difference in gender, age, age of onset, education level and disease duration between the AD-SD and AD-NSD groups(P>0.05). The factors in the PSQI scale had significant differences between AD-SD和AD-NSD groups, including sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, administration of sleeping medication and daytime dysfunction(P<0.05). Compared with the AD-NSD group, the AD-SD group showed that the total score of MoCA scale was significantly reduced(P<0.05), and the scores of delayed recall and language were significantly decreased(P<0.05). There was a negative correlation of the sleep time with the total score of MoCA scale and the score of delayed recall in the AD-SD group(r=-0.245 and -0.249, P=0.041 and 0.039). Night SD was negative correlated with the total score of MoCA scale and the score of delayed recall(r=-0.248 and -0.283, P=0.038 and 0.018). Conclusions The incidence of AD-SD is up to 79.78%.AD-SD patients have a worse subjective sleep quality, longer time to fall asleep, shorter sleep time, lower sleep efficiency, higher night SD, more use of sleep drugs and more daytime dysfunction.General cognitive dysfunction, delayed recall and language impairment are more obvious in AD-SD patients.In AD-SD group, longer time to fall asleep and night SD are related to the general cognitive function and delayed recall.
