1 The approach of LVB cannulated by passed retrograde across the aortic valve can be performed easily and reduce LV pre-load and LV work, as well as cardium oxygen consumption significally; 2 This LVB can improve coronary artery perfusion and cardiac function while AOMP can be maintained after LAD occlusion; 3 There has a potential impariment effect on the right ventricular function with excessive amount BFR (over 85%) during LVB, particularly in the present of myocardial ischemia; 4 Roller pump is not suited for a prolonged bypass because of significant damage to the blood system.

由此我们得出以下实验结论：经外周动脉逆行左室置管转流方法操作简便、迅速。能明显减少左室前负荷，减少左室作功，降低心肌耗氧量；能维持严重心脏缺血后的平均动脉压，改善冠脉循环灌注和左室功能，具有临床应用的可行性。85%以上转流率对缺血心脏的心功能有潜在的损害效应。以75%左右转流率较为合适。转子泵不适宜用作长时间转流。

Methods The Wistar rats were used as the experimental animal. On the back of each rat, a skin flap, measuring 1.5 cm×6 cm, caudally based, was elevated. Wound edges and the flap bed were separated from the flap itself by a silicone sheet. The VitC, bFGF, Magnesium sulfate and Papaverine were taken in the areas between flap and sheet. With 8 rats in each group, the drug-taken group was as trial group, while the physiological saline group was as control group. On the seventh day after the flap elevation, flap survival length was measured.

以鼠背部中线为中轴，以两侧髂嵴连线为蒂，形成一个1.5cm×6cm的单蒂皮瓣，其全长自皮肌层下与深筋膜游离，下垫置医用硅膜，硅膜以不露出切口，又起到阻隔真皮血运为宜，以小三角针用3-0丝线先缝合皮瓣两侧切口，然后将上述4种药物加入皮瓣与硅膜之间，再缝合皮瓣的头端将维生素C、bFGF、硫酸镁、罂粟碱分别作为实验组，以生理盐水作为空白对照组，每组8只动物，术后单笼喂养7d，取材并检测皮瓣存活的长度。

Plantlet regeneration from cotyledon of Citrullus lanatus cv. Zhangkang No. 4 was studied. The results showed that aseptic seedlings should be cultured in dark for 3d, then exposed to a photoperiod of 16/8h/d for 3d. The callus induction rate was higher in cotyledons placed facing downwards to the medium than in those facing upwards. The highest induction rate occurred in MS medium containing 6-BA (2.0mg/L), kinetin (1.0mg/L)and GA3 (1.0mg/L). The induction initiated in dark and took 7 days, while callus growth and differentiation proceeding for 7 days under 16/8h light-dark cycles. A highest rate of embryogenic callus was obtained after 3 successive subcultures.

以无子西瓜郑抗4号无菌苗子叶为外植体，进行了体细胞胚发生及植株再生的研究，结果表明，无菌苗应先进行3d暗培养，然后采取光照16h/d和黑暗8h/d培养3d；将子叶的叶面朝下放置于培养基上的愈伤组织诱导率高于叶面朝上的培养方式；子叶诱导胚性愈伤组织的最适培养基配方为MS+6-BA2.0mg/L+KT1.0mg/L+GA31.0mg/L；诱导需要在黑暗条件下启动，进行7d暗培养，而生长分化于光照16h/d和黑暗8h/d条件下培养7d；继代3次得到的胚性愈伤组织最多；最适生根培养基配方为1/2MS+IBA0.3mg/L。

Closer to the official opening ceremony, people were starting to gather in Plaza Consistorial, where the ceremony was held, and the adjoining Plaza Castillo. Plaza Consistorial was transformed into a big, open-air party. People were chanting, tossing large balloons and splashing each other with red wine or champagne. Those on the balconies around the square also joined the folly and treated those below them with buckets of water, one after one. It all sounded fun until the crowd became too close for comfort and some people had the clever idea of pushing the others in all directions, while ground was becoming ever more slippery. The whole scene was indeed on a slippery slope itself!

快11点时，人群已逐渐在举行开幕礼的市政广场及相连的城堡广场聚集，我到达市政广场时，看到的只是一个大型户外狂欢派对，在一片欢呼和高歌中，大家不是忙着把那些大气球抛来抛去，便是互相喷红酒、香滨，站在露台的，时而也会从高浇水助兴，爱玩的人当然觉得好玩，但当后来人多得插针不入，地下又湿滑，有时无端端又有人「推波助澜」时，实在是有点危险！

RESULTS Duodenal ulcer was the first cause of upper gastrointestinal hemorrhage. Gastric ulcer, cirrhosis, Mallory-Weiss syndrome or acute gastric mucous lesion was the second cause of the illness alternatively. The rate of endoscopy and emergent endoscopy has been going up year after year and got up to 80% in 1998. Bleeding and active hemorrhage, respectively were found in 24.3% and 14.9% of the patients underwent endoscopy before medication. Endoscopic hemostasis was performed in 108 patients by spraying hemostatics and a good response was achieved subsequently. Hemostatics were mainly cimetidine and yunnan baiyao before 1994. Reptilase, pPI, famotidine and ranitidine were used increasingly while cimetidine and yunnan baiyao were used decreasingly. Octreotide was used in patients with cirrhosis commonly. The length of hospital stay and the period from admission to bleeding cease tended to be shorter year by year, but the reduction rate was small. The uses of ranitidine, famotidine, pPI, reptilase, octreotide, early endoscopy and endoscopic therapy may play a role in improving the therapeutic effect of hemostasis, reducing the hospitalization and the mortality.

结果 十二指肠球部溃疡是历年上消化道出血的首要原因，胃溃疡、肝硬变、Mallory -Weiss综合征、急性胃粘膜病变则交替成为第2位出血原因；内镜诊断率和急诊内镜率逐年提高，1998年达到80%，内镜下见出血者占内镜检查的24.3%，而见到活动性出血者仅占内镜检查者的14.9%；内镜下止血108例次，成功率100%；1994年前治疗药物主要为云南白药和甲氰咪胍，之后，随着立止血、质子泵抑制剂、法莫替丁、雷尼替丁等药物使用的逐渐增多，前二者的使用逐渐减少，善得定多用于肝硬变出血；住院天数和止血天数呈逐年下降的趋势，但幅度微小；雷尼替丁、法莫替丁、PPI、立止血、善得定的使用以及及时的内镜检查和内镜下治疗在提高止血效果、缩短住院天数、降低死亡率方面可能起到了一定作用。

Chapter 4 includes an overall analysis of the scale and regional distribution of the backflow and it is found that although the scale has been expanding, yet it is distributed disproportionably among different regions, specifically the East China occupying a comparatively larger percentage while the middle and west areas only a small proportion, and the unbalanced distribution has not changed much even after the reform in the tuition system and the implementation of Enrollment Expansion Policy.

分析结果表明，我国高等教育人才对农村的回流规模是不断扩大的，但是高等教育人才回流在地区之间的分布是不均衡的。东部地区占有了相对较多的回流人才，中西部地区较少。高等教育收费改革和扩招以后，人才对农村的回流率不断提高，回流规模继续扩大，但回流人才在地区之间的分布特征基本没有改变。
