Research Progress on the Relationship between Folate Deficiency and Commonmentaldisorders / 中国药学杂志

Folate is a water-soluble vitamin. Deficiency of folate may not only lead to abnormal neural tube development in the embryo, but also affect brain function. This paper reviews the association of folate deficiency with depression, anxiety, obsessional disorder, schizophrenia and other psychiatric disorders, as well as the effect of folate supplementation on adjuvant therapy for psychiatric disorders.

Dynamic Posturography of Injured Lower Limb in Postural Evoked Response / 法医学杂志

OBJECTIVE@#To analyze the balance function of injured lower limb by dynamic posturography.@*METHODS@#Using the dynamic posturography instrument, the postural evoked responses of sixty-two normal people and two hundred and fifty-eight people with injured lower limb bones and joints were detected. The test was included sensory organization test (SOT) and adaption test (ADT). The results of two groups were compared by t test.@*RESULTS@#Compared with the normal people, the impaired people had significant statistical differences in balance scores of SOT3-SOT6 and proportion score of dynamic proprioception (P < 0.05). There was no obvious decrease in ADT.@*CONCLUSION@#The balance function of injured lower limb significantly decreases.

Posture evoked response detecting in normal lower limb muscle and its influencing factors / 法医学杂志

OBJECTIVE@#To analyze the latency of posture evoked response of normal lower limb muscle in different stimulations and explore its influencing factors.@*METHODS@#The normal lower limb was induced to produce postural evoked response by the dynamic posturography through two kinds of perturbations, the supporting surface rotation stimulation (Toes-up and Toes-down) and the horizontal perturbation stimulation (Forward and Backward). The latencies of tibialis anterior muscle and gastrocnemius muscle were recorded by surface electromyography acquisition system. The differences of the left and right limb, gender and height on the latency of postural evoked response were analyzed.@*RESULTS@#(1) Under the Toes-up and Backward perturbation, the latency of tibialis anterior muscle was longer than gastrocnemius muscle; under the Toes-down and Forward perturbation, the latency of gastrocnemius muscle was longer than tibialis anterior muscle. (2) The latencies of left limb and right limb had no significant difference. (3) The latency in male was longer than that in female. (4) The latency gradually increased with the increase of height.@*CONCLUSION@#In the postural evoked response, different perturbations, gender and height have significant impacts on the latency of posture evoked response of lower limb muscle. However, the effect of height and gender should be not considered referring to the same individual.
