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 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 explore the risk factors of dysphagia in the patients with traumatic brain injuries (TBI). Methods 141 TBI patients were assessed with Gugging Swallowing Screen, and divided into the dysphagia (n=36) and normal (n=105) groups. The related factors were compared between 2 groups. Results The frequency increased in severe brain injury, brain stem injury, bilateral brain injury, tracheotomy, nasal-gastric tube insertion and cognitive defect in the dysphagia group compared with those in the normal group (P<0.05). Conclusion The severe brain injury, brain stem injury, bilateral brain injury, tracheotomy, nasal-gastric tube insertion and cognitive defect may be related with the dysphagia post TBI.

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 assess the prevalence of depressive symptoms,trends on its longitudinal development and related influencing factors among primary and middle school students in Changfeng county of Anhui province. Methods Through cluster sampling methods,all students from 3 to 9 grades in 5 primary schools and 3 middle schools in Changfeng county of Anhui province were investigated through questionnaire as subjects of baseline survey in December 2009. Subjects of this longitudinal study were students in grades 3,4 and 7 at the time of the baseline survey and were contacted once a year for two years. At last,a total of 816 students participated in all the three surveys. A structured questionnaire including Children’s Depression Inventory,socio-demographic characteristics and some potential influential factors was employed for this study. A Generalized Estimating Equation (GEE) was used to evaluate the related influencing factors of children’s depressive symptoms in the longitudinal study. Results Prevalence rates of depressive symptoms were 11.3%,10.4% and 8.5%,respectively,at the baseline,1-year and 2-year follow-up studies, among primary and middle school students. Scores on depressive symptoms of total subjects and children who had always been left at home in the follow-up process showed significant differences at the three surveys (F=13.423,P<0.001;F=5.761,P=0.003). 25 percent of the 92 students who showed depressive symptoms at the baseline survey remained those depressive symptoms at the 1-year follow-up study and 87 percent of the 23 students who had depressive symptoms at the baseline and 1-year follow-up surveys still showing depressive symptoms at the 2-year follow-up study. Results from the GEE program indicated that grade 3 students,having syblings,family with dysfunction or at low level of self-esteem etc.,were prone to development while sex and parents’ educational level were not correlated with depressive symptoms. Conclusion Prevalence of depressive symptoms among primary and middle school students in Changfeng county of Anhui province appeared a decreasing tendency during the follow-up process in our study. Through the longitudinal development,we noticed that the prevalence of depressive symptoms seemed to be related to the personal characteristics,education and family environment of the subjects under our study. Improving the level of family function as well as individual’s self-esteem might positively contribute to mental health of those primary and middle school students.
