However 20(39%) patients appeared obvious T wave change among th e 52 patients with non-conceal assessory pathway after RFCA,including the 19 pa tients they passed through cmplete accessory pathway (QRS duration≥140 ms) and only one patient is incomplete accessory pathway (QRS duration ＜140 ms).

结果：80例隐匿性旁路在射频消融术后无1例出现心脏复极改变，52例显性旁路中有20例(占39 %)术后出现女性明显 T波变化，其中完全性旁路(QRS≥0.14 s)占19例，而不完全性旁路(QRS＜0.14 s)仅占1例。

RESULTS:Amo ng the 80 patients with conceal accessory pathway,no one had episodes of T wave change by RFCA. However 20(39%) patients appeared obvious T wave change among th e 52 patients with non-conceal assessory pathway after RFCA,including the 19 pa tients they passed through cmplete accessory pathway (QRS duration≥140 ms) and only one patient is incomplete accessory pathway (QRS duration ＜140 ms).

The fEPSP response evoked in one pathway was small, usually 20–30% of the maximu, whereas a large response, usually 80–90% of the maximum, was evoked in the strong pathway. After recording of the baseline fEPSP evoked at 0.033 Hz, LTP of the weak pathway could be associatively induced by paired stimulation of the weak and strong pathways 100 times at 6 sec intervals, with stimulation of the weak pathway preceded 3–10 msec.

在记录以0.033Hz所引发基础的兴奋性突触后电位之后，在弱的路径上可以因配合弱与强的刺激路径而引发出相关性长期增益（每六秒一次共100次，弱的刺激路径在强的刺激路径之前 3-10 ms），然而当在两个路径之间的配合时间差大於10 ms时即无法形成相关性长期增益，此类型长期增益的引发是需要依赖活化NMDA接受器的，因为给予50 mM的D，L-AP5可以阻断相关性长期增益的引发（兴奋性突触后电位为原来的105±6﹪；n=6）。

We found that wogonoside and 7- O -glucuronide chrysin were the metabolites presenting in the rat urine samples after oral administration of baicalin by LC-MS-MS,which had never been reported.
