By using the method of eross-sectional anatomy, we examined human eerebral asymmetries in 31 Chinese adult brain.The left cortical language areas is larger than the right. The distribution of the hemispheric asymmetries is compatible with that reported by CT scan.The asymmetry of the posterior language areas mainly reflect the asymmetry of the occipital length and the asymmetries of the wide occipital lobe and the wide occipital horn might be in relation to the handedness. Though both the anterior and the posterior language area are mostly larger on the left hemisphere,there is no relationship between them

BACKGROUND: Reversion total hip arthroplasty for inflammatory pseudotumor is little reported.OBJECTIVE: To investigate the prognosis of the reversion total hip arthroplasty for inflammatory pseudotumor and the related factors.METHODS: Eighty-one patients failed metal-on-metal hip arthroplasty were recruited, the medical history, baseline data and information of primary arthroplasty were collected, and all preoperative examinations were completed prior to reversion. The postoperative joint function was evaluated by Hospital for Special Surgery score, and the morphology of prosthesis was observed by radiology. Additionally, the serum levels of cobalt and chromium ions were detected, as well as the incidence of complications and the related factors were analyzed.RESULTS AND CONCLUSION: (1) There was a significant increase in Hospital for Special Surgery hip score and significant decrease in serum levels of cobalt and chromium ions after reversion (P=0.000). (2) The postoperative incidence of complications and secondary reversion rate was 16% and 6%, respectively. (3) Preoperative prosthesis loosening (P=0.012), tissue cirrhosis revealed on MRI (P=0.000) and the injury degree of tissue (P=0.049) were found to be related to the incidence of complications. (4) Kaplan-Meier curve showed that the survival rate of prosthesis was 88% at 30 months postoperatively. (5) These results suggest that the prognosis of reversion total hip arthroplasty is poor,which is related to the preoperative aseptic loosening, tissue cirrhosis surrounding the joint and intraoperative tissue injury, thus providing guidance for surgeons to make an appropriate operative scheme.

Objective To explore which category of pictures could induce neutral emotion better for male and female respectively,and investigate the effects of inducing neutral emotion with eight categories of neutral pictures,including the nature,plants,animals,humans,culture,death-waste,food and computer graphics.Methods Using selected stimuli from the simple version (revised by Huang and Luo(2004)) of the International Affective Picture System (IAPS),the rating of calm-mood degree were collected for 135 neutral pictures based on 186 undergraduate students (78 male and 108 female).Results The pictures in the categories of plants(6.87 ±1.53),nature(7.00 ± 1.73) and culture(6.93 ± 1.37) induced neutral emotion significantly better than human (5.89 ± 1.49),computer graphics (5.94 ± 1.93) and food (5.87 ± 2.03) (P ＜ 0.05) which were better than animals (5.03 ± 1.70) and death-waste (4.71 ± 1.94) (P ＜ 0.05).In addition,gender difference was found in rating calm-mood degree for death-waste,people and animals categories.For these categories males showed higher rating for the calm-mood degree than females (P＜ 0.05),while for the other categories,there was no gender difference.Conclusion The ideal categories of neutral pictures that inducing neutral emotion are plants,nature and culture.This study provide empirical evidences for selecting and using pictures to induce relative calm mood in the emotional study,and the contribution of this study to the clinical research is discussed.

Objective:To evaluate the influence of sodium hypochlorite (NaOCl) solution used during root canal therapy on dentin bond strength.Methods:In the study,15 freshly extracted human third molars with complete dental crowns,caries and filling-free were selected.The occlusal enamel was removed perpendicular to the long axis of the tooth to expose middle flat surfaces of sound dentin.The occlusal dentin surfaces were then polished using 600-grit silicon papers for 1 min and rinsed with deionized water for 1 min.The teeth were randomly divided into three groups according to the treatment received:group A (negative control group),the samples were immersed in deionized water for 20 min;group B,the dentin surfaces were immersed in 2.50％ NaOCl solution for 20 min,with the solution being renewed every 5 min;group C,the dentin surfaces were immersed in 5.25％ NaOCl solution for 20 min,with the solution being renewed every 5 min.All the treated dentin surfaces were bonded using a self-etching adhesive system (SE bond) with a 5 mm in height resin composite (AP-X).After storage in deionized water at 37 ℃ for 24 h,the adhesive samples were sectioned longitudinally to produce 1.0 mm ± 1.0 mm stick specimens (n =45) for micro-tensile bond strength testing (MPa).Failure modes (adhesive failure,cohesive failure or mixed failure) at the dentin-resin interface were observed using a stereomicroscope.The micro-tensile bond strength data among the three groups were analyzed by a one-way ANOVA,then the Post-hoc test(LSD) was employed for pairwise comparison.The distribution of failure modes among the groups were analyzed by chi square test.Results:Significant decreased bond strength values were found for the 2.50％ NaOCl-treated group (26.04 ± 5.74) MPa and 5.25％ NaOCl-treated group (24.46 ± 3.77) MPa when compared with the strength of negative control group (48.71 ± 7.77) MPa,P =0.000.Compared with the negative control group,themicro-tensile bond strength of the 2.50％ NaOCl-treated group and 5.25％ NaOCl-treated grouphad dropped by 46.5％ and 50.2％.However,there was no significant difference of bond strength between the 2 NaOCl-treated groups (P =0.214).The distribution of failure modes showed significant difference in all the three groups (2 =56.324,P =0.000).The mixed failure (68.9％) was the most mode of fracture in the negative control group,followed by adhesive failure (24.4％),and the cohesive failure was leas t (6.7％).The proportion of adhesive failure mode was higher in NaOCl-treated groups than in negative control group (P =0.000).There was no significant difference of the distribution of failure modes between the 2.50％ NaOCl-treated group and 5.25％ NaOCl-treated group(P =0.197),and there was no cohesive failure mode detected in the two groups.Conclusion:The micro-tensile bond strength of dentin to composite resin was lower after exposure to NaOCl solution.
