Objective To explore the diffusion-weighted magnetic resonance imaging (DWI) and apparent dispersion coefficient(ADC) value in cerebral infarction diagnosis and judgment of cerebral infarction outcome and staging of the value.Methods According to different stages,26 patients were divided into 3 phases,phase Ⅰ (6 ～72 h) had 11 cases,phase Ⅱ (4 ～ 10 d) had 12 cases,phase Ⅲ (10 d later) had 9 cases,of which 3 cases were reviewed,3 cases were recurrence of cerebral infarction.Each patient's MRI included T1 weighted imaging,T2 weighted imaging,DWI and ADC sequence scan image reconstruction,the ADC map obtained one regions of interest (ROI),and the mean ADC value of ROI were calculated,the average ADC value of the corresponding contralateral area were also calculated by the same method,and then the mean relative ADC value were calculated.Results DWI image of all cases showed high signal,11 cases showed high signal and 1 case showed low signal in phase Ⅱ.In phase Ⅲ,1 case showed normal signal and 1 case showed high signal,2 cases showed mixed signal,1 case were reduced,and the rest were all low signal.Compared with the contralateral corresponding region,the average ADC values were reduced in phase Ⅰ.The infarction average ADC values were 0.434 × 10 3mm2/s,0.653 × 10-3mm2/s,1.600 × 10-3mm2/s in phase Ⅰ,Ⅱ,Ⅲ respectively,and the average ADC values of contralateral corresponding region were 0.938 × 10-3 mm2/s,0.814 × 10-3 mm2/s,0.757 × 10-3 mm2/s respectively; the mean relative ADC values were (51.5 ±16.8)％,(79.2 ±30.0)％,(210.9 ±45.1)％ in phase Ⅰ,Ⅱ,Ⅲ respectively (P ＜ 0.05).Conclusion ADC value of cerebral lesions area and relative ADC value of the variation in time provides an objective basis for the diagnosis of DWI,contributes to timely and accurately determine the age of cerebral lesions and pathophysiology of the changes.

Objective: To observe influence of aerobic exercise on blood pressure in patients with white coat hypertension (WCH). Methods: A total of 51 newly diagnostic WCH patients were randomly divided into exercise group (n=26) and WCH control group (n=25). Patients in exercise group received aerobic exercise training (walking on flat ground by constant speed, twice a day, 50~80 min each time for three months); The WCH control group did not exercise. Office blood pressure (OBP) and 24h ambulatory blood pressure monitoring (ABPM) were measured in both groups before and three months after treatment. Results: There were no significant difference in indexes of OBP and ABPM between two groups before treatment (P>0.05). After three months, compared with before treatment, indexes of OBP and ABPM significantly decreased in exercise group and they were significantly lower than those of WCH control group in OBP [OSBP: (132.54±17.60) mmHg vs. (143.68±20.35) mmHg, ODBP: (89.12±18.39) mmHg vs. (92.75±17.24) mmHg] and ABPM [ mSBP：(121.57±20.86) mmHg vs. (128.06±19.45) mmHg, mDBP：(76.24±15.28) mmHg vs. (84.55±17.31) mmHg; dSBP：(124.27±22.50) mmHg vs. (130.85±24.61) mmHg, dDBP：(77.95±18.42) mmHg vs. (82.36±17.59) mmHg], P<0.05~0.01. Conclusions: Aerobic exercise can significantly improve blood pressure in patients with white coat hypertension.

Objective: This research carried out the native assessment to the Montreal Battery of Musical Evaluation, including MBEA and Musical emotion test. Methods: 60 normals were tested by MBEA (including 30 university students). Also 40 students were tested by musical emotion recognition battery. The correct rates were recorded and compared with western normals’data. Results: There were significant differences in pitch judgments and musical emotion recognition be- tween Chinese and Westerners, while rhythm perception and memory of music did not have significant difference between the two groups. Conclusion: Culture difference mainly influences the musical pitch perception in brain but rhythm. Chinese have its own understanding of western musical excerpts. Although MBEA is wildly accepted abroad, native analogy testing tool is acquired.
