Abstract
AIM:  To observe the influence of acupuncture on event evoked potential
P3 latency aml wave aml)litude in autistic children with lan~:uage
disorders.
METHODS: Thirty autistic children, who were treated in the Department
of Pediatric Encephalopathy,  Haishu District Hospital of Traditional
Chinese Medicine of Ning;ho City between September 2000 and Septemher
2002, were divided into acupuncture ~:roup (n,=20) and control g:roup (n=10)
acx:ording; to their order of admission.  The patients in the acupuncture
groulr') were treated with acupuncture at .sishen,zhen.,  n,iescnzzhen.,
nnosanzhen., Umzhizhen., shesan,zhen., shousanzhen., shouzhizh,en., zusan,zhen,
zuzlzizhen., .fen,gclzi an,ci yamen. acpoints, once a day, 30 minutes for each
time, 10 minutes for each acupuncture; There was a 2-day rest every week,
and 4 weeks as a c:ourse for 4 courses;  The patients in the control group
were treated with Zhikang oral solution  (tuber fleeceflower root,  polygala
root, lon~;an aril, g;lossy privet fruit, dragon's bone and tuckahoe, containing
crude drug of 3 ~:/mL) and piracetam oral solution, 3 times a day, 10 mL
for each time,  they were treated for 4 continuous weeks.  The changes of
two kinds of event related potential P3 wave amplitude an latency were
detected with JaF)anese MEB-4 200 evoke potential meter before and after
treatment respectively; The event related potential P3 latenr,y could reflect
the r,odin~ sorting and identifying{ velocity of cerebrum to stimulation, and
P3 wave amplitude was associated with the numher of cerebral cortical
synapse aml attentive status to evaluated the electrocerebral changes
caused by psycholog<ical activities.
RESULTS:  According; to intention-to-treat analysis,  all the 30 patients
were im,nlved in the analysis of results.  O P3 latency:  It was ohviously
shortened after treatment in the acupuncture g;roup as compared with that
hefore treatment [(492.19+31.04), (525.64+39.26) ms, t=8.48, P < 0.01],
but there was no significant {lifference in the control ~:roup hefore and after
treatment [(510 38+23 29), (518.23+26.35) ms, t=1.97, P > 0.05]; The
difference before and after treatment in the acupuncture g;roul) was
sig;nificantly greater than that in the control grour) [(33.45 +8.22),
(7.85+3.06)  ms,  P < 0.01].  ③ P3 wave amplitude:  It w'as ohviously
im:reased after treatment in the acupuncture g;roup as c:ompared with that
before treatment [(5.98+1.63), (4.66+1.24)¨V, t=2.21, P < 0.05], but there
was no sig;nificant difference in the control g;roup hefore and after treatment
[(4.85+1.09), (4.72+1.05) yV, t=1.48, P > 0.05]; The differew.e before and
after treatment in the acupuncture grc)up was significantly greater than that
in the control group [(1.32+0.39), (0.13+0.04) L,V, P < 0.01].
CONCLUSION:  Acupuncture can effectively shorten the event related
I)otential P3 latency in autistu} children,  indicating that ac:u[)un",ture
treatment accelerates nervous impulse conduction,  the recognizing and
F)rocessin9: time of cerebrum to environmental information.  After
acupuncture treatment,  the P3 wave amplitude of autistic c:hildren is
increased,  it is indicated that acupuncture can promote the g:rowth and
development of' nerve fiber in children with developing; disorder,   im:rease
the numl)er and quality of cerebral cortical synapse;  It also improves the
level of attention in autistic {:hildren as much as possible,  and increases
the numher of neurcms that can be activated.

摘要
目的:观察针刺对孤独症语言障碍儿童事件相关电位P3潜伏期和波幅
的影响。
力法:选择2000-09/2002-09在宁波市海曙区中医医院儿堂脑病科治
疗的儿童孤独症30例,按就诊顺序分为针刺组20例和对照组10例。
针刺组取四神针、颞三针、脑三针、头智针、舌三针、手三针、手智针、足
三针、足智针、风池、哑门,针刺1次/【1,30 min/次,10 min行针1次,每
周休息2d,4周为1个疗程,共治疗4个疗程。对照组口服智康口服液
(由何首乌、远志、龙眼肉、女贞子、龙骨、袄苓等组成,含生药3 g/mL)、
吡拉西坦口服液,3次/d,每次各10 mL,连续治疗4个月。治疗前后使
用日本MEB-4 200诱发电位仪检测2组事件相关电位P3波幅和潜伏
期的变化,事件相关电位P3的潜伏期口J反映大脑对刺激进行编码、分
类和识别的速度,P3的波幅与大脑皮质突触数目及注意状态有关,评
估其由心理活动产生的脑电变化。
结果:按意向处理分析,30例患儿均进入结果分析。OP3潜伏期:针刺
组治疗后较治疗前明最缩短『( 492.19+31.04),(525.64+39.26)ms,t=8.48.
P< 0.01],对照组与治疗前比较无差异[(510.38-cl3.29),(518.73+'16.35)ms,
t=1.97,P>0.05],治疗前后差值针刺组显著高于对照组f(33.45+8.22),
( 7.85+3.06)ms,P<0.01]。②P3波幅:针刺组治疗后较治疗前明甚升高
『(5.98±1.63),( 4.66+1.24) pLV,t=2.21.P<0.05],对照组与治疗前比较无
差异『(4 85±1.09),( 4.72+1.05) pLV,t=1.48,P>0.05],治疗前后差值针刺
组碌著高于对照纽『(1.32±0_39),( 0.13+0.04) VV,P<0.01]。
结论:针刺能有效缩短孤独症儿童事件相关电位P3潜伏期,提示针刺
治疗使神经冲动传导加快,大脑对外界信息的认知加上时间缩短。孤独
症儿童针刺治疗后P3波幅升高,提示针刺町以促进发育受阻的患儿的
神经纤维的生长发育,增加大脑皮质突触的数目与质量,同时,尽口J能
提高了孤独症忠儿的注意水平,增加了能激活起来的神经元数量。
主题词:孤独性障碍/针灸疗法;事件相关电位,P300;针刺
O  引言
    P3是事件相关电位中潜伏期在300 ms以后出现
的一个止向成分,它是当人注意到某客体并进行认知
加工时,在头皮上记录到的电位,又称"P3认知诱发电
位”。关于P3的人量研究结果表明,它是与注意、辨认、
决策、记忆等认知功能有关的事件相关诱发电位成分,
现在己广泛应用于心理学、医学、测谎等领域。孤独症
儿童由于其社会交往障碍、智力低下、语言障碍等,理
解力差,很难按照要求完成任务P3的检测,凶此,作者
采用无任务P3探讨针刺对其认知发育的影响。

P3的提取、叠加、测量均在诱发电位含义上的编辑程
度及脑电图编辑程度上进行。每叠加20次后所获波
甲滑3次后,进行P3波幅、潜伏期测量。检测时,让受
试者听耳机中的声音,指导语是:“小朋友,请仔细听
这里面的声音,不要动,不要哭,不要说话。”
    P3波辨认方法与测量:在刺激300 ms以后出现
的第1个止向波,在其前面有一个较人的负向波N2。
P3有时是双峰波。测量时,以波幅高者为准;若波幅相
等,则以P3的上升度与下降度二者延长线的交点作
为测量P3潜伏期的起点。
    主要观察指标:两组患儿治疗前后事件桕关诱发
电何中P3潜伏期与波幅。
    统计学分析:由广州中医药人学第一作者采用
Excel.SPSS 10.0统计软件进行检验,£检验。
