Objective The purpose of this study was to investigate the differences of cognitive impairment and neuropsychiatric behavior disturbances between Alzheimer's disease (AD) and frontotemporal dementia (FTD) patients,as well as their relationships with dementia severity.Methods A total of 38 FTD patients and 46 AD patients were recruited in this study.The Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) were used to evaluate the degree of cognitive impairments.The Neuropsychiatric Inventory Brief Questionnaire Form (NPI) and Frontal Behavioral Inventory (FBI) were used to measure behavioral disturbances.The 21-items Hamilton Depression Rating Scale (HAMD-21) was used to evaluate the mental or emotional state of patients.Clinical dementia rating scale (CDR) was used to divide the dementia severity.Results FTD patients were younger ((70.13 ± 8.36) years vs (66.46 ± 7.04) years,t =2.124,P =0.037),earlier at age of onset ((68.58 ± 8.51) years vs (64.43 ± 6.82) years,t =2.396,P =0.019),with lower MoCA scores (12.50 (8.00,16.25) vs 17.00(10.75,21.00),Z=-2.428,P=0.015),higher NPI (15.00(7.00,25.50)vs 9.50(4.00,17.75),Z=-2.251,P=0.024),FBI (21.00(13.00,27.00)vs 16.00(10.75,23.00),Z=-2.159,P=0.031),FBI-A (13.00 (8.00,16.00)vs 9.00(6.00,12.00) Z=-2.159,P=0.041),FBI-B (9.00(7.00,14.00) vs 7.00(3.00,11.00),Z=-2.051,P=0.040) and HAMD-21 scores (7.00(2.75,14.00) vs 5.00 (3.00,8.00),Z =-2.061,P =0.039).A detail analysis of different cognitive domains showed the executive functions (Z =-2.140,P =0.032),language (Z =-3.357,P =0.001),abstraction (Z =-2.498,P =0.012) and delayed recall (Z =-4.317,P =0.000) of the MoCA scale were lower in FTD patients than that in AD patients,while AD patients had lower scores in memory (Z =-1.999,P =0.046) and orientation (Z =-2.941,P =0.003) of the MMSE scale.Within the subscale scores of the NPI,the agitation (Z =-3.255,P =0.001),disinhibition (Z =-3.093,P =0.002) and irritability (Z =-2.214,P =0.027) scores were higher in FTD patients than in AD patients.The total scores of NPI (r=0.279,P=0.010),FBI (r =0.353,P=0.001),FBI-A (r=0.386,P=0.000) and FBI-B (r =0.273,P =0.012) were positively correlated with the CDR scores,whereas MoCA scores were negatively correlated with the CDR scores (r =-0.760,P =0.000).The subscale scores on MoCA and NPI areas changed corresponding with dementia severity in both groups.Conclusions The cognitive function,behavioral and psychological symptoms between FTD and AD patients are different.FTD patients have poorer executive function,language,abstraction and delayed recall ability,whereas AD patients perform worse in memory and orientation.With the progression of the disease,FTD patients gradually emerged disorientation,while the cognitive impairment in AD patients almost affected all the areas.FTD patients are more likely to have agitation,disinhibition and irritability behavior,and AD patients are more likely to have depression in the late stage.Dynamic evaluation of the cognitive function,behavioral and psychological symptoms in clinical practice can help to distinguish FTD and AD.

Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.

Objective To investigate the changes of electrode impedance,threshold(THR),maximum comfortable level(MCL),and dynamic range(DR),providing the basis for debugging after operation in congenital deaf children. Methods A respective study was carried out on 20 cases of congenital deaf children who were implanted with cochlear Med?EL SONATAti100. The measurements and changing ranges of electrode imped?ances,THR,MCL and dynamic range during the operation and at postoperative one month,three months,and six months were statistically analyzed. Results Electrode impedances were the lowest during the operation and the highest at one month after operation(P<0.01). The electrode imped?ance for the apical cochlear group was statistically different from that for other groups at one month(P<0.05). After three and six months,there were statistically significant differences between groups(P<0.01). THR at six months was lower than that at three months(P<0.05). MCL at three months was higher than that at one month(P<0.01). DR showed an increasing trend(P<0.05). There was no correlation of perioperative and post?operative electrode impedance with THR,MCL,and DR(P>0.05). Conclusion The electrode impedances varied due to different electrode posi?tion. The vales of THR,MCL and DR were unrelated with electrode impedance. DR was gradually increasing,MCL reached steady state earlier than THR. It is important that THR should be debugged at three months after operation and MCL should be debugged at six months.

Objective:To explore the application of speckle tracking imaging (STI) stratification strain technique in the assessment of circumferential myocardial function and the myocardial protection of ATP-postconditioning (ATP-PostC) in a rabbit model of acute myocardial infarction.Methods:A total of 40 rabbits were randomly divided into 2 groups: pure ischemia reperfusion group (IR group)and ATP-PostC group. STI images were recorded before and 45 min after occlusion of coronary artery, post low-dose dobutamine stress echocardiography, 60 and 120 min after reperfusion, respectively. The following parameters were obtained: left ventricular ejection fraction(LVEF), heart rate (HR), endocardial circumferential systolic strain (CSsys-endo), mid-myocardial circumferential systolic strain (CSsys-mid) and epicardial circumferential systolic strain (CSsys-epi) at left ventricular short-axis level. At different time points after occlusion and reperfusion, 5 experimental rabbits were killed in each group for pathological examination.Results:①Forty-five min after coronary artery occlusion in both groups, the values of LVEF and HR were decreased( P<0.05), and the absolute values of CSsys-endo, CSsys-mid and CSsys-epi were significantly reduced( P<0.01). After LDDSE, the absolute values of CSsys-endo, CSsys-mid and CSsys-epi were increased, which were different from those after blockade( P<0.05). ②After reperfusion, the circumferential strains were not significantly different from those after blockade in IR group ( P>0.05). After blockade, the absolute values of circumferential strains were increased significantly in the ATP-PostC group compared with IR group( P<0.05). In the ATP-PostC group, the absolute values of CSsys-endo at different time points after reperfusion increased significantly compared with that after blockade ( P<0.05). The absolute values of CSsys-endo and CSsys-mid 120 min after reperfusion continued to increase significantly compared with those 60 min after reperfusion( P<0.05). ③Pathological examination: After 60 min of blockade, there was no significant difference in myocardial infarction area between the IR group and the ATP-PostC group( P>0.05). The percentage of infarct areas at each time point of reperfusion in the ATP-PostC group was decreased compared with that after blockade( P<0.05). Compared with the IR group, the percentage of infarct area in the ATP-PostC group was smaller after 120 minutes of reperfusion and the difference was statistically significant ( P<0.05). Conclusions:The applications of STI stratification strain technique and LDDSE can assess left ventricular circumferential strains at each of myocardial layers before and after reperfusion in rabbit myocardial ischemia ATP-PostC model, identify and evaluate the function of viable myocardium, and exhibit the significant protective effects of ATP-PostC on myocardial reperfusion injury.

OBJECTIVE: To evaluate the instructional effect of Multi-slice (MSCT) in the cochlear implantation pre- and post-operatively, and to contrast the image feature between the X-ray and the MSCT three-dimensional reconstruction of inner ear with implanted electrode. METHOD: Twenty-four cochlear implant (MEDEL Combi 40+) recipients,in No. 1 Hospital of China Medical University from January to October 2014, were involved in this study. Among them, 18 were male and 6 female,with an average age of 4 years. MSCT and three dimensional reconstruction of inner ear were performed in all of the 24 implanted inner ears pre- and post-operatively. And X-ray plain film were examined by using 60° lateral oblique position postoperatively. All data of the spiral CT scan with axial 1 mm image slices were transferred to workstation for three-dimensional reconstruction (direct volume rendering) of the inner ear. RESULT: In 1 of the 24 cases, preoperative three-dimensional reconstruction CT scan reveal that the length of the cochlear was shorter than the electrode. And this was confirmed by MSCT postoperatively that the electrode couldn't be inserted by full length. The insertion depth of the electrode can be evaluated directly by MSCT. Moreover, each of the electrode pairs can be identified clearly. CONCLUSION MSCT plays an indispensable role in the preoperative evaluation of cochlear implantation. Postoperative evaluation by three-dimensional reconstruction of inner ear provide more accurate image to show the electrode insertion depth in the cochlea. MSCT combined with curved planar reformation to measure cochlear length could provide guidance in choosing the more adaptive electrode. And MSCT is superior to DR in demonstration of electrode postoperatively.
