Objective To probe into the social support, coping styles, and mental health status of medical staff in a tertiary hospital in Beijing, for identifying potential mental problems. Methods Such means as the Social Support Rating Sheet (SSRS), Simple Coping Style Questionnaire (SCSQ), Symptom Checklist (SCL-90), and demographic characteristics questionnaire were called into play, to study 2460 medical staff in five tertiary hospitals in Beijing. Results Differences were identified among medical staff of different demographic characteristics, in terms of positive coping style and support dimensions. Analysis of the survey data indicates that the total SCL scores, total symptom problem index, positive symptom pain level, total average score of the factors, are positively related to passive coping style, as P<0. 01; and are negatively related to subjective/objective support, support utilization, and total support scores, as P<0. 01. Conclusions Hospital administration is expected to implement focused intervention to such medical staff as those under 40 years old, women, widows or divorcees, those with education lower than university degree, those with junior academic title or lower, those without titles, those in emergency departments and emergency intensive care units, doctors and nurses, frequent night-shift workers, those of excessively low self evaluation, and medical staff with chronic diseases. The purpose of this practice is to alleviate their mental stress.

Objective To explore the normal range of cingulate cortex volumes of Chinese adults of the Han nationality and its relationship with age, which provide morphological data for the construction of database for Chinese Standard Brain.Methods This is a clinical multi-center study.One thousand Chinese healthy volunteers ( age range = 18 to 70) recruited from 15 hospitals were divided into 5 groups, i.e.,Group A (age range = 18 to 30), B (age range=31 to 40), C (age range =41 to 50), D (age range =51 to 60), and E (age range =61 to 70).Each group contained 100 males and 100 females.All of the volunteers were scanned by MR using T1 weighted three-dimensional magnetization prepared rapid acquisition gradient echo sequence.Cingulate cortex volume (including bulk volume and the left/right volume) was measured semi-manually using 3D volume analysis software.Cingulate cortex volumes among age groups were compared by one-way ANOVA.Right and left cingnlate cortex volumes between sexualities were analyzed by paired samples t test.The relationship between cingulate cortex volume and age was analyzed by Pearson correlations and regression analysis.Results Cingulate cortex volumes of male and female were (20 347 ± 2504) and ( 19 432 ± 2184) mm3 respectively, and the male's was significantly larger than that of female's (two sample t'-test for independent samples, t'= 6.156, P < 0.05 ).Right and left cingnlate cortex volumes of male were ( 10 717 ± 1629) and (9630 ± 1498) mm3 respectively, and those of female's were ( 10 064 ± 1407 ) and ( 9368 ± 1441 )mm3 respectively.The volumes of cingulate cortex were significantly different between right and left in male or female ( t = - 12.960, - 8.511, P < 0.05 ),and right was larger than left.Bilateral cingulate cortex volume in male among group A, B, C, D and E[left: ( 10 132 ± 1291 ), ( 10 113 ± 1638), (9599 ± 1576), (9594 ± 1288), (8710 ± 1212) mm3 ; right:(11 212±1442), (11 096±1602), (11 040±1403), (10 633±1638), (9604±1522) mm3] had statistical differences (F = 16.738, 18.707, P < 0.01 ) ; and those in female among five age groups[left:(9689 ± 1426), (9652 ± 1676), (9347 ± 1500), (9098 ± 1225), (9053 ± 1233) mm3 ; fight: ( 10 558 ±1325), ( 10 266 ± 1463), ( 10 100 ± 1497), (9779 ± 1304), (9617 ± 1254) mm3] also had significant differences (F = 16.859,7.528,P <0.01 ).Bilateral cingnlate cortex volume in both male and female were negatively correlated with age ( r = - 0.330, - 0.324, - 0.169, - 0.243, P < 0.05 ), though the correlation coefficient is not high.Conclusions Cingnlate cortex volume could be accurately measured on the high-resolution MRI with 3D volume analysis software, which can provide morphological data for the construction of database for Chinese Standard Brain.The results may provide normal range for the diagnosis of the volumetric deficits of cingulate cortex.

Objective To explore the normal range of the volume of frontal lobe in Chinese adults of the Han nationality and provide morphological data for the construction of database for Chinese Standard Brain. Methods This is a clinical multi-center study. Two hundred Chinese healthy volunteers (age range= 18 to 70) recruited from 16 hospitals were divided into 5 groups, i. e. , age range from 18 to 30, age range from 31 to 40, age range from 41 to 50, age range from 51 to 60, and age range from 61 to 70. Each group contained 20 males and 20 females. All of the volunteers were scanned by MR using T1 weighted threedimensional magnetization prepared rapid acquisition gradient echo sequence. We used the manual method to trace the region of interest and measured the left and right frontal lobe volumes separately. All the data were analyzed with SPSS (version 13.0). The sex differences in the frontal lobe volumes were analyzed by independent-samples t test, and the side differences were analyzed by paired-samples t test. Correlation and regression analysis was used between the age and the frontal lobe volumes. Results In 200 healthy Chinese Han volunteers, the total frontal lobe volumes was (563 ± 73) cm3. For male, the volumes of the left and the right frontal lobe were (288±42) cm3 and (292 ±41 ) cm3 ,respectively. The volumes of the left and right frontal lobe in 100 women were (273 ±30) cm3 and (274 ± 30) cm3 respectively. The differences of sex (t = 3. 334, P < 0. 05 ) and side ( t = - 3.09, P < 0. 05 ) in the total frontal lobe volumes reach significant. There was no significant differences in women ( t = - 1. 304, P > 0. 05 ). There were negative correlations between the frontal lobe volumes and age in men and women ( r = - 0. 586, - 0. 498, P <0. 01 ). Conclusions The total frontal lobe volume of men was larger than that of women. The volume of the right frontal lobe was larger than the left frontal lobe in men, and the asymmetries didn't exist in women.The total frontal lobe volumes were both shrinking with age in men and women, which was more rapid in men than in women.

Methods This is a clinical multi-center study. One thousand Chinese healthy volunteers (age range = 18 to 70) recruited from 15 hospitals were divided into 5 groups, i. e. , Group A (age range = 18 to 30), B (age range =31 to40), C (age range =41 to 50), D (age range=51 to 60),and E (age range =61 to 70). Each group contained 100 males and 100 females. All of the volunteers were scanned by MR using T1 weighted three-dimensional magnetization prepared rapid acquisition gradient echo sequence. The margin of HPF were outlined manually for each side. Using multiple linear regression,relationships between hippocampal volume and sex, age, weight and height were analyzed respectively.Independent two sample t test was used to study the differences between male and female and between lcft and right. The differences of hippoeampal volume among age groups were analyzed by ANOVA. Results Hippocampal volume for left and right side were (4752 ± 659) and (5032 ± 660) mm3 respectively. The volume of HPF is significant correlated with gender and age, but without relevance to height and weight ( left and right r = 0. 283,0. 311, F = 30. 127,37. 050 ,P < 0. 01 ). The volumes of left and right hippocampus were (4897 ± 670), (5192 ± 667)mm3 respectively for men, and (4647 ± 624) and (4904 ± 630) mm3 for women. The right hippocampal volume was larger than the left ( t = 7. 030,6. 696, P < 0. 05 ). On both sides, men have larger hippocampus than that of women ( t = 6. 586,7. 326, P < 0. 01 ). The volumes of the left hippocampus among the five age groups in the male were (4981 ± 684), ( 5003 ± 609 ), (4976 ± 657 ),(4841 ± 631 ), (4631 ± 681 ) mm3 respectively, while the volumes of the right hippoeampus were (5340 ±647) ,(5276 ±582), (5264 ±620), (5133 ±661 ), (4894 ±699) mm3 respectively. Among age groups,the differences were statistically significant ( left and right F = 5. 737,7. 607, P < 0. 01 ). For male, there was significant difference of bilateral hippoeampus between the 18-30, 31-40, 41-50 years group and 61-70 years group ( P < 0. 05 ) and there was no significant difference among the other groups ( P > 0. 05 ).There was no significant difference of hippocampal among different groups in women (P > 0. 05 ).Conclusions With high-resolution MRI, the volume of the HPF was accurately measured, so as to provide the basic data for research of the hippocampus-related disease.
