Result:the incidence of AP went up year by year;(2)bile tract disease is the major reason,but hyperlipdemic AP should be attach importance to for its higher and higher incidence;(3)mean age of biliary AP is higher than alcohlolic and hyperlipdemic AP;(4)the difference of sex is significant in biliary AP and alcohlolic AP;(5)the incidence of local omplications is lower than alcohlolic and hyperlipdemic AP,but the difference is of no significance in view of systemic complications;(6)lungis of the most liability for dysfunction,and renal dysfunction is most closely related to death ;(7)ESS is associated with AP and related to the severity and prognosis .

会阴切开阴道助产术在第二产程中为避免会阴及盆底严重裂伤，减轻盆底组织对胎头的压迫、缩短第二产程、加速分娩、降低新生儿窒息率具有很大的意义，只有合理掌握手术的指征以及避免过多干预和进行手术助产，会阴切开阴道助产术就可取得良好的效果，侧切率就能得到很好的控制，否则将会产生一系列并发症，对母婴带来很大的危害。

A few abnormal ECG such as sinus tachycardia, sinus arrhythmia, sick sinus syndrome decreased with age. The incidence of sinus bradycardia and preexcitation syndrome were bail shape with age. Half of abnormal ECG adults had at least two abnormal ECG, such as STT changes combined with ventricular premature beats or bundle branch block.
