[Abstract ] Objective The spleen plays an important role in brain ischemia-induced cerebral injury.This study aimed to ex-plore the correlation of the spleen mass index with the neurological function scores and infarction volume following permanent occlusion of the middle cerebral artery ( pMCAO) in rats. Methods Thirty male SD rats were equally randomized into a sham operation, a 3-day brain ischemia, and a 7-day brain ischemia group.The pMCAO model was established by ligation in the right brain of the rats. Neurological function scores were obtained with the Longa 5-Point Scale at 0, 3, and 7 days after modeling, and at 3 and 7 days, the spleen mass index was calculated, the infarction volume measured by TTC, and brain histopathological changes evaluated by HE stai-ning. Results Compared with the 7-day ischemia group, the 3-day ischemia rats showed significantly reduced spleen mass index ([1.62 ±0.58] vs [0.87 ±0.59] mg/g) and increased neurological function score (1.00 [1.00, 1.25] vs 2.00 [1.75, 2.25]) and infarct volume ([18.67 ±7.92] vs [36.20 ±14.92]%) (all P<0.05).An extremely significant decrease was found in the spleen mass index of the 3-day ischemia rats in comparison with that of the animals in the sham operation group ([1.90 ±0.22] mg/g) (P<0.01).HE staining revealed more obvious pathological injury of the cerebral cortex in the 3-day than in the 7-day group.The spleen mass index was negatively correlated with the neurological dys-function score (r=-0.851, P=0.019) and infarction volume (r=-0.717, P =0.013). Conclusion In pMCAO rats, measure-ment of the spleen mass index contributes significantly to the preven-tion and improvement of ischemia-induced cerebral injury.

Objective Through the research on relationship between achievement motive and personality traits,to provide the basis theory of personality attributes for selecting outstanding medical professional scientifically and effectively,and give some advice for improving medical education mode.Method The 310 medical staffs in sample hospital were treated as the research object in October 2015,who were randomly investigated with the big five personality questionnaire and achievement motivation scale,among of which,valid questionnaires were 290 copies leading to 93.5％ effective rate.SPSS 17.0 software was used to make t test,Chi-square analysis and correlation analysis for the data of the recover valid questionnaires.Result ①Personality traits of friendliness and rigor of the medical staffs of different gender exist statistically significant difference (t=-7.39,P=0.00;t=-8.28,P=0.00) and there were significant differences in the openness and rigor of medical staffs of different gender (P＜0.05).②The achievement motivation level of male medical staffs was higher than that of female (P=0.00),and there was no significant difference in achievement motivation among medical staffs.③The personality trait of neuroticism was negatively correlated with the pursuit of success and achievement motivation (correlation coefficient was-1.24),while the achievement motivation was positively related to extraversion and openness and the pursuit of success (the correlation coefficients were 1.51 and 1.53).Conclusion There is a significant correlation between personality traits and achievement motivation.The more extroverted personality medical staffs have,the more easy-going they are,and the more the pursuit of success oriented achievement motivation they have;and the higher the neurotic tendency individuals have,the more they incline to avoid failure of achievement motivation.

Objective To study the expression of 2 bone morphogenetic protein (BMP) related microRNA (miR-21,miR-155) in SLE patients,and to analyze their correlation with clinical features.Methods Peripheral blood was obtained from 59 SLE patients and 25 healthy controls,and total RNA was extracted and reverse transcribed into complementary DNA (cDNA).Real-time PCR technique was used to detect gene expression at transcrptional level.Disease activity was determined by SLEDAI score.Patients were divided into different groups based on their manifestations or antibody profiles,then comparison of miRNA expression was carried out using Mann-Whitney test.Results The expression levels of miR-21 and miR-155 were increased in active SLE patients (SLEDAI≥8) as compared to those with mild disease (SLEDAI≤7) or healthy controls (both P＜0.05).Patients with positive anti-dsDNA or lupus nephritis had higher expression levels of miR-21 and miR-155 than those without (P＜0.05).Conclusion The miR-21 and miR-155 expressions are elevated in active SLE patients and are associated with anti-dsDNA and renal involvement.The results suggest that these two miRNAs might play a role in the pathogenesis of SLE disease.
