No Ⅲ° atrioventricular conduction block happened, 9 patients developed right bundle branch block, and 2 patients showed junctional rhythm. Two patients with perimembranous extending outlet were repaired because of residual shunt(0.4cm,0.3cm) on the anterosuperior rim of defect. One patient with trivial residual shunt(0.15cm) on the posteroinferior rim of defect was found closed spontaneously six months later. Tricuspid valve was incised in 10 patients of VSD sextending outlet,8 patients vertical to the valve ring,2 patients parallel to the valve ring. Moderate tricuspid valve regurgitation was found in 1 patient, mild in 5 patients, trivial in 4 patients. No one aggravated. One patient complicated with pericardial effusion.

无Ⅲ°房室传导阻滞发生，9例发生右束支传导阻滞，2例结性心律。2例膜周偏流出道型VSD患者因前上缘残余分流分别为0.4cm和0.3cm，再次手术修补；1例后下缘残留细束样分流，直径0.15cm，随访6个月后自愈；10例膜周偏流出道型VSD患者剪开三尖瓣，8例垂直瓣环，2例平行瓣环；1例三尖瓣中度反流，随访无加重；5例轻度反流，4例轻微反流，随访均无加重；1例心包积液；1例再次进入手术室止血。

Background— Mild commissural mitral regurgitation is associated with significantly higher restenosis-free surial after percutaneous mitral aluloplasty, which suggests that different mechanisms of significant MR after PM may hae different clinical courses.

背景 经皮二尖瓣成形术后轻度的联和部二尖瓣返流患者术后无再狭窄生存率明显较高，提示着成形术后不同机制的显著二尖瓣返流有不同的临床进程，因此对成形术后显著二尖瓣返流患者的长期预后因素进行了分析

Background— Mild commissural mitral regurgitation is associated with significantly higher restenosis-free surial after percutaneous mitral aluloplasty, which suggests that different mechanisms of significant MR after PM may hae different clinical courses.

背景：经皮二尖瓣成形术后严重高度非再狭窄存活率与轻度交界处损伤的二尖瓣关闭不全相关，表明经皮二尖瓣成形术后严重二尖瓣关闭不全的不同机制可能有不同的临床过程。

Methods The mitral (M1) and tricuspid (T1) valves componented of the first heart sound (S1), the aortic (A2) and pulmonary (P2) valves componented of the second heart sound (S2) were detected by short-time Fourier transformation spectrogram and Shannon engergy, in the high frequency resolution circumstance.

在频率分辨率较高的情况下，利用短时傅立叶变换声谱图和香农能量，提取出第1心音(S1)的主要成分二尖瓣关闭音(M1)、三尖瓣关闭音(T1)及第2心音(S2)的主要成分主动脉瓣关闭音(A2)、肺动脉瓣关闭音(P2)。

Results In standard large trauma craniectomy group,21 cases got good recovery(65.6%) and 5 were dead(15.6%).

结果标准外伤大骨瓣减压手术治疗组32例中，恢复良好21例(占65.6%)，死亡5例(占15.6%)；常规骨瓣开颅手术组24例中，恢复良好9例(占37.5%)，死亡10例(占41.7%)。2组对比，恢复良好率和死亡率差异有统计学意义(P.05)，标准外伤大骨瓣减压手术治疗组预后明显优于常规骨瓣开颅手术组。

The prevalences of tricuspid and pulmonic regurgitation increased with age, reached the peak values at the age of 8-9 years of age, and decreased gradually afterwards.

三尖瓣、肺动脉瓣返流的发生率随年龄增长而增加，8～9岁时达高峰，随后渐下降；二尖瓣及主动脉瓣返流发生率随年龄改变不明显。

They are associated with stenosis of either the aortic or the pulmonic valve, with hypertension or dilatation of either the aorta or the pulmonary artery or both.

喷射性喀喇音喷射性喀喇音音调高，出现于收缩早期，与主动脉瓣或肺动脉瓣狭窄有关，也与主动脉瓣或肺动脉瓣或两者的高血压或膨胀有关。

Tricuspid regurgitation was most commonly found and was detected in417(45.8%) children, pulmonic regurgitation in225(24.7%), mitral regurgitation in12(1.3%), and aortic regurgitatioin in5(0.5%).

结果495名有一组或一组以上的心脏瓣膜返流，发生率为54.4%三尖瓣返流最常见，有417名5.8%；肺动脉瓣返流次之，有225名(4.7%；二尖瓣、动脉瓣返流少见，分别有12名。3%和5名

The aortic diameter change rates were (-0.2±1.4) mm/year and (-0.18±0.98) mm/year in aortic diameter0 mm group and≥40 mm group, respectively. There was no significant difference between the two groups. The ascending aortic diameter change rates were (0.8±1.6) mm/year in BAV group, and (-0.3±1.5) mm/year in TAV group. The ascending aortic diameter of patients in BAV group enlarged continuously following AVR.

在升主动脉直径0mm组和≥40mm组中，升主动脉直径的变化率分别为(-0.2±1.4)mm/年和(-0.18±0.98)mm/年，两组之间无显著性差异；二叶主动脉瓣组和三叶主动脉瓣组升主动脉直径的变化率分别为(0.8±1.6)mm/年和(-0.3±1.5)mm/年，二叶主动脉瓣组病人的升主动脉直径在主动脉瓣置换术后仍继续扩大。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
