Objective To investigate the ability of social cognition in patients with right temporal lobe infarction.Methods Fifteen patients with temporal lobe infarction (TLI) and 20 healthy controls (HC) were examined with the recognition of faux pas and reading the mind in the eyes tasks for assessing the ability of social cognition.Results The TLI group performed significantly worse when compared with the HC group (28.6 ± 6.1,36.4 ± 4.3 respectively) as revealed in the total faux pas-related scores (U =41.00,P <0.01).For the control question,there was no significant difference between the TLI group and the HC group (9.86 ±0.35,10.00 ± 0.00 ; U =130.00,P =0.097).In the reading the mind in the eyes task,patients with TLI performed worse than the HC group(17.13 ±6.41,29.75 ±2.07 respectively),and the difference had statistical significance (U =0.00,P < 0.01).But there was no significant difference in gender recognition judgment (30.37 ± 1.16,31.35 ± 1.08 respectively; U =106.00,P =0.129).Conclusions The right temporal lobe involves in social cognition.Moreover,the right temporal lobe not only involves in the verbal related social cognitive processing,but also involves in the no-verbal related social cognitive processing.

To explore the effect of icariside ? on osteoprotegerin(OPG) expression in osteoblasts, primary osteoblasts were cultured with different concentration of icariside ? and 17?estradiol. As a major metabolite of icarrin in vivo, icariside ? exerted a better effect on OPG expression which plays a key role in osteoporosis. 20 ng/dl icariside ? also exerted better effect on OPG secretion than that of positive control group. Consequently, icariside ?could be a candidate for osteoporosis treatment.
