Objective To propose A brain computer interface paradigm based on the combination of the motion-onset visual evoked potential(mVEP) and the steady state visual evoked potential(SSVEP).Methods By designing a 3 ×3 character spelling matrix,a vertical white bar in the column of matrix which flicks at a pre-set frequency induced the corresponding SSVEP.The vertical white bar also randomly moved horizontally so as to induce mVEP.Then the two types of features were extracted by time frequency analysis.Finally the support vector machine was applied to compare the target character identification rate between the proposed paradigm and the single mVEP paradigm.Results The target character identification accuracy of subject S1 and S6 was improved by about 2% comparing the proposed paradigm to the single paradigm.Other subjects achieved the improvement of 6% for the same performance comparison.The averaged identification accuracy of the proposed paradigm could reach 91.4% if the same stimulus repeated for more than 3 times,while the accuracy of single paradigm achieved 85.6%.Conclusions The proposed brain computer interface paradigm could effectively induce many kinds of brain feature signals.The identification accuracy by the proposed paradigm is higher than that by the single paradigm for various numbers of repeated trials.The proposed paradigm of combined visual stimulus merges the motion induction and the flash frequency modulation together and hence reduces the stimulation time and increases the efficiency of the feature extraction.

BACKGROUND:In recent years, there are many animal studies and osteoblast studies on the anti-osteoporotic effects of puerarin, a kind of phytoestrogen. But few of them are reported on the effects of puerarin on osteoblasts in older patients with osteoporosis. OBJECTIVE: To observe the influence of puerarin on the proliferation ofin vitro cultured osteoblasts from older female patients with osteoporosis. METHODS:The older female patients with osteoporotic femoral neck fractures who underwent artificial femoral head replacement were included in this study. The femoral neck cancelous bone removed during the operation was colected. Primary cancelous bone osteoblasts were cultured using explant culture method. The cels were sub-cultured to the required amounts. Osteoblasts from the control group were cultured with culture medium without puerarin. Osteoblasts from the 0.01, 0.1, and 1 μmol/L puerarin groups were cultured with culture medium containing the corresponding concentrations of puerarin. After in vitro co-culture with different concentrations of puerarin for 1, 3, 5 days, the proliferation of osteoblasts was observed. RESULTS AND CONCLUSION:With the increase in the concentration of puerarin, the proliferative activity of
osteoblasts constantly increased at different time points (P < 0.05). At 3 days of culture, cel absorbance value in each group reached the peak level. These results suggest that 0.01, 0.1, 1μmol/L puerarin promotes the proliferation of osteoblasts in older patients with osteoporosis in a concentration-dependent manner.

OBJECTIVE:To investigate the effects and safety of erythropoietin on nerve function and brainstem auditory evoked potential in the preterm children with brain damage. METHODS:46 preterm children with brain damage were randomly di-vided into treatment group and control group,with 23 cases in each group. Control group received conventional symptomatic treat-ment as respiratory support,nutritional support,vitamin K supplement and ganglioside. Treatment group was additionally given rhE-PO for injection (CHO cell) 500 IU/kg hypodermically,3 times a week,on the basis of control group. Both group received 3-4 weeks of treatment continuously. MDI,PDI,the content of serum nerve injury factor(NSE,S-100β),latent period and peak inter-val of brainstem auditory evoked potential were compared between 2 groups before and after treatment,and the occurrence of ADR was observed in 2 groups. RESULTS:There was no statistical significance in MDI,PDI,the content of serum nerve injury mole-cule,latent period and peak interval of brainstem auditory evoked potential between 2 groups before treatment (P>0.05). After treatment,MDI and PDI of 2 groups increased significantly,while the content of serum nerve injury factor,latent period and peak interval of brainstem auditory evoked potential decreased significantly;the treatment group was better than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Erythropoietin can significantly im-prove intelligence development,protect the damaged nerve cells and auditory nerve pathways with good safety.
