No structural change was found in the 4th group. Conclusion The test prove that cholestasis would occure during TPN and become serious with time prolonging. Integrity and function of gallbladder-wall tissue cell could be defended and sustained by applying GLN, but there is no direct preventing action. There is apparent cholecy stokinetic and cholagogic fundations by applying CCK. But CCK would lose its function if gallbladder-wall was damaged. The test prove that TPN+GLN+CCK is the best way to prevent cholestasis during TPN.

TPN时间越长，胆汁淤积越重； GLN虽无直接收缩胆囊作用，但它可保护胆囊壁组织结构完整，而CCK虽有收缩胆囊、减轻胆汁瘀积作用，但晚期当胆囊壁组织结构破坏时，其作用减弱；联合应用GLN和CCK可能是预防TPN期间胆汁瘀积的一种方法。

Results Pores were detected both on electrified erythrocytes and leukocytes with round or ellipse shapes. The erythrocytes often have one or more pores while the leukocytes often have more pores looked like cribble.

As the density of Al and Cu was quite difference,it was apt to delaminate and restrain the process of alloy by wet milling.The case was improved when dry milling,though it would be some reunite with the time of ball-milling prolonging.(2)The best technique parameters of high energy ball milling to prepare metastable powders of Cu-Al alloy were;the addition of Al powders was 1% in quality,the powders of Cu-Al were completely alloyed after high energy ball milling for 20 h.

1提出采用高能球磨制备Cu-Al合金粉的有效方法，认为由于Cu和Al的密度相差比较大，采用以液态酒精为过程控制剂的湿磨时，容易发生分层，抑制了合金化，采用干磨时，以硬脂酸为过程控制剂，虽然随球磨时间的延长会发生轻微的团聚，但能达到良好的合金化效果。

延长反应时间和提高反应温度有利于二硝化产物的形成，缩短反应时间和降低反应温度有利于单硝化产物的形成。

The experiment that aPplication of Put shows that Put can inhibit chlorophyll discomposing and lower POD activity; Lower concentration (about 5mmol/L) can decrease respiration rate; ethylene's synthesis result in prolonging the storage time; Higher concentration (about l0,20mmol/L) Put can activate the respiration in some degree and disadvantage to storage.

外源腐胺处理香蕉果实的实验表明，腐胺可以减缓叶绿素的降解，另外，低浓度的（5mmol/L左右）腐胺可以较好的抑制乙烯的生成和呼吸作用，延缓果实衰老，而高浓度（10、20mmol/L）则在一定程度上刺激了呼吸作用，对贮藏不利。

At the BCL of 500ms, 1000ms and 2000ms,the VWtimes increased markedly with the BCL prolonging, and the degree of increasing was even obviously when heart rate was slow (BCL=2000ms or 1000ms). The enlargement of VWs was a most important reason to increase the incidence of ventricular arrhythmias; 2）At the BCL of 500ms, 1000ms or 2000ms,the VWtimes of the premature stimulates S2 was at endomembrane were wider than at the outermembrane. We supposed that premature stimulates come from endomembrane was easier inducing VF compared with outermembrane;3The VWtime of unidirectional block was wider than reentry's, we can see that reporlarization dispersion changed dynamicly. 4The QRS polar of the premature stimulates was opposite the primary beats ,which suggesting that excitation of inducing premature beats was coming from epicardial. That is to say electrotonic potential take part in the creation of reentry;5With the ratio of the Tp-e/QT increasing the occurrence of VF was upgrading. So the ratio was an effective method to estimate the event of SCD.6 The VWtimes of S3 were broaden than S2's. But we can not study penetratingly, which is the contents of our future studies.

在BCL为500ms、 1000ms和2000ms刺激条件下，随着刺激周长的增加单向传导阻滞时间易损窗呈增大趋势；并且在心率较慢时(BCL为2000ms和1000ms)增大最明显，是LQTS患者室性心律失常发生率增加的原因之一；2）在BCL为500ms、 1000ms和2000ms刺激条件下，S2位于内膜侧时时间易损窗大于在外膜侧时的，推测来自于内膜侧的期前刺激易于诱发室性心律失常；3）折返激动时间易损窗小于在单向传导阻滞时间易损窗，折返易发生于S2刚进入单向传导阻滞区间时，这说明复极梯度的不均一是动态变化的；4心电图上倒置QRS波与正常S1刺激所引起QRS波极性相反，提示不同位置S2刺激引发的室性早搏的兴奋均来自于外膜侧，说明了电紧张电位扩布参与了折返的产生；5）Tp－e/QT可以反应跨膜复极离散度，随着Tp－e/QT比值的增加PVT的发生增多，其可以用来预测室性心律失常的发生。6）随着期前刺激数目的增加时间易损窗增大。
