At 2years after OPBPV,right ventricular end-diastolic volume and end-systolic volume were still significantly bigger than control group (P ＜0.01) in all patients but right ventricular ejection fraction was normal,RVEDV dilatant rate correlated very well with DB/Dp ratio significantly.

RVEDV较未手术组的扩大率与球/瓣比间有非常显著相关(P＜0.01)，RVESD扩大率与球/瓣比间有相关趋势，但球/瓣比与术后即时、3月、＞2年的ΔP↓率间无显著相关(P＞0.05)。

In Gastrochilus the lip is semiglobose-saccate with indistinct side-lobes and a much larger mid-lobe, the column is footless and the pollinia are porate, while in Saccolabium the lip is cylindrical-spurred with indistinct side-lobes and a small mid-lobe, the column has a short foot and the pollinia are solid.

Methods Adult New Zealand white rabbits (n=10) as recipients were divided into 5 groups and one-month age New Zealand white rabbits (n=20) served as donors. The homograft valved conduits harvested from the donors were transplanted into the bilateral aorto-carotid in 10 recipients. The homografts were harvested from one group at 7, 14, 28, 60, 120 days after transplantation to examine blood flow and thrombus of homografts.

成年新西兰兔10只作为受体分5组。1个月龄的新西兰白兔20只作为供体，取其主动脉带瓣血管，移植于受体的两侧颈动脉，术后7、14、28、60、120 d分别取出每组受体所移植的同种瓣并观察血流通常情况及有无血栓形成。

objectiveto evaluate the result of using rectangular advacement flaps for repairing the eyelid defects at the edges of palpebra.methodswe have used rectangular or double rectangular advacement flaps to repair the defects of theantieror margin of eyelid in 36 cases.to repair the posterior margin defects ,when the defects of thetarsal plates were shorter than 5mm,the tarsal plates were closed directly , longer than 5mm ,sliding tarsal palpebral conjunctive flaps were to be used.resultsin 36 cases all of the flaps were survived with primary healing, slight scar, no absence of eyelashes, no notch deformity at the edge of palpebra, no trichiasis.

目的：探讨应用矩形推进皮瓣修复睑缘眼睑缺损的效果。方法：对36例睑缘肿物切除的眼睑缺损患者，采用矩形或双矩形推进皮瓣修复眼睑前层缺损。眼睑后层睑板缺损小于5mm者，采用直接缝合法；睑板缺损大于5mm者，采用睑板睑结膜瓣移行法。结果：36例患者皮瓣全部成活，切口ⅰ期愈合，手术瘢痕轻微﹑睫毛无缺失﹑无倒睫﹑睑缘圆滑无切迹畸形。

Results:No significant difference was found between the stiffness of intact left and right clavicles.

结果：完整锁骨左右两侧的扭转刚度无显著性差异(P＞0.05)，切取半片骨瓣后其扭转刚度显著下降(P＜0.01)，锁骨在切取短骨瓣与切取长骨瓣后两者相比较其刚度、强度变化不大。

Results In univariate analysis, atrial fibrillation, huge left atrium, long course of left-sided valve diease, degradation of left heart function （LVEF 〈0.50）, tricuspid rheumatic pathological change, enlarged right atrium and single mitral valvar disease were significant risk factors of TR devdopment.

结果单因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长、左心功能低下（LVEF〈0.50）、右房增大（≥50mm）、三尖瓣风湿性病变及单纯二尖瓣病变是继发性TR进行性加重的危险因素；多因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长及三尖瓣风湿性病变是继发性TR进行性加重的危险因素；远期随访显示，B组心功能改善明显优于A组，TR程度明显低于A组，C组术后无1例发生TR。
