A case-control study on family environment related factors in attention deficit hyperactivity disorder with anxiety disorder / 中华流行病学杂志

Objective To study the family rearing pattern of attention deficit hyperactivity disorder(ADHD)with or without anxiety disorder and to explore its risk factors.Methods 9495 children and their parents were sampled at random in Hunan province,using two-stage investigation.Those who were diagnosed ADHD and the normal control filled out Egna Minnen av Barndoms Uppfostran and family adaptability and cohesion scale bv themselves.Results The comparison of factors as:actual family cohesion,parents' punishments,reiection,mother's excessive protection,intervention and father's excessive protection were significantly difierent between ADHD with or without anxiety disorder and normal children(P＜0.05).The comparison of parents' punishments,reiection,excessive protection and intervention were obviously different between ADHD with anxiety disorder and simple ADHD(P＜0.05).Mother's reiection was the influencing factor of simple ADHD,with OR as 1.122.Ideal family cohesion,mother's rejection and father's punishments were the influencing factors of ADHD with anxiety disorder,with OR as 0.966.1.215 and 1.089 respectively.Conclusion There were some problems in the parental rearing pattern of ADHD with or without anxiety disorder.Mother's rejection,father's punishments and ideal family cohesion were suggested to be correlated with ADHD and anxiety disorder.

Effects of testosterone and cortisol in sports fatigued organism by Chinese material medica of shixiang yaofa / 中国中药杂志

<p><b>OBJECTIVE</b>To study the endogenous hormone of testosterone and cortisol that secretes volume and rhythm in sports fatigued human bodies and animals. To determine secretory volume and rhythm in sports fatigued human bodies and animals when Shixiang yaofa's drug are used.</p><p><b>METHOD</b>Radio-immunity method was used to determine secretory volume and rhythm in sports fatigued human bodies and animals and to analyze secretory volume and rhythm. According to the secretory volume and rhythm of testosterone and cortisol, the Shixiang Yaofa's drugs were used. Doses: wenyang jihuo bead 10 g/sack 2 sack, ziyin xiuyang capsule 0.5 g/pill 8 pill pd in human bodies for 28 days. Wenyang jihuo bead 10 g x kg(-1) of crude drug, ziyin xiuyang capsule 4 g x kg(-1) of crude drug pd for hight doses in animals. Other groups for low doses 5 g x kg(-1) and 2 g x kg(-1) of crude drug pd for 15 days. The blood samples were collected for determination.</p><p><b>RESULT</b>(1) In human bodies the peak value of testosterone was appeared in 8:00 and valley value was appeared in 18:00, ranges: 176.93-281.73 x 10(-5) mg x L(-1). The peak value of cortisol was appeared in 8:00 and valley value was appeared in 22:00, ranges: 1.31-16.13 x 10(-3) mg x L(-1). In the same condition, the mouse peak value of testosterone was appeared in 20:00 and valley value was appeared in 0:00, ranges: (0.56 x 10(-5) - 124.0 x 10(-5)) mg x L(-1). The rhythm in animals was compatible with human bodies, howerer, the peak value was delayed for 12 hours. (2) The testosterone was step up and the cortisol was cut down in sports fatigued human bodies and animals when shixiang yaofa's drug were used (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>The secretion of testosterone and cortisol in sports fatigued human bodies and animals are existed conclusive biologic rhythm. The secretory volume can be available accommodation by shixiang yaofa's drugs.</p>
