在过去，常常将腹部正中线耻骨与肚脐中间定为穿刺点，现在，由于腹腔穿刺引流大量液体以及腹中部脂肪厚度增加，左下腹成为腹腔穿刺部位（表1），在左下腹部中线至髂前上棘连线上2指宽（3cm）与距髂前上棘2指宽，已经显示较中部脂肪少及腹水较多是治疗性腹腔穿刺好的首选部位27，在盲肠有扩张或阑尾切除术后瘢痕时右下腹是次选的穿刺部位，应避开腹壁下动脉，这些血管走行在耻骨与髂前上棘之间的中线然后在腹直肌中向上行走，，腹壁可见的侧支循环亦应该避开，腹腔镜检查发现侧支循环可出现在中线并且在腹腔穿刺时有导致血管破裂的风险28。

At the root canal therapy process, hidden in the root canal isthmus, bifurcation area, triangle, shape and irregular dentinal tubules within the Enterococcus faecalis prepared by mechanical means it is difficult to remove, it can be biofilm, proton pump tolerance mechanisms such as root canals harsh ecological environment, to avoid conventional drugs, the role of disinfection, resulting in the failure of root canal therapy.

在根管治疗过程中，隐藏在根管峡部、分叉区、三角区、形态不规则区及牙本质小管内的粪肠球菌难以用机械预备的方法去除，它可通过生物膜、质子泵等机制耐受根管内苛刻的生态环境，躲避常规消毒药物的作用，从而导致根管治疗的失败。

Unlike standard chemotherapy,treatment with the molecular targeted anti-tumor agents is associated with an increased incidence of dermatological toxicities.

分子靶向抗癌药物的毒副作用迥然不同于传统的细胞毒药物，尤其是其最为常见的皮肤毒性，可引发身体和心理的明显异常，导致药物的减量或中断从而影响治疗的效果。

by analyzing internal and exterior factors working on the validity of professional sports service production institution, the paper concludes that on the one hand, with ectogenic, compellent, defective structure low maneuverability and human degree in the chinese professional sports production institutions, which result in low validity of professional sports production institution in china; on the other hand, for the whole nation systems and common property right dominated by china government, china economy systems' transition, confucian culture that pays more attention to academic knowledge, whereas despise on physical force, which greatly influence the efficiency of professional sports service production institution.

摘 要：通过分析影响竞技体育生产制度有效性的内在因素和外部因素，得出：一方面，中国竞技体育生产制度由于其外生与强制性、制度结构欠缺、可执行性程度低、人性化程度差等原因导致其制度有效性低，另一方面，中国政府主导的&举国体制&和竞技体育的公共产权、中国经济体制转轨、&重文轻体&的儒家文化极大地影响竞技体育生产制度效率的发挥。

EV71 brainstem encephalitis is a complication clinically characterized by fever, hand-foot-and-mouth disease, and myoclonus jerk after the infection.

肠病毒感染是全身性的，多器官系统性的，但其临床表现可自轻微无症状的表现到严重的并发症包脑膜炎、脑炎、心肌炎、肝炎等甚至会导致死亡的病例。

Results:pedunculated omentum majus-cirded trachea transplantation ensured an early re-establishment of blood circulation of transplanted trachea and maintenance of its normal animate states; allogeneoilc transplantation of trachea activated bodys immune mechanism. resulting in a chronic process of rejection and finally leading to progressive necrosis of transplanted trachea tissues: chondroregeneration occurred at every period under perichondrium after transplantation. and the degree of regeneration was related with favorable blood circulation; the emplogyment of a supporting tube in trachea,under the condition of favorable re-establishment of early blood circulation, could preventgranulation tissue hyperplasia and keep trachea cavity unobstructed.Postgraduate Ding XiaoQuan Directed by-Lin LeShen

结果 带蒂大网膜包绕移植段气管行腹腔移植，早期重建了移植段气管的血液循环，保证了移植气管的早期成活及维持其正常生机状态；同种异体气管移植所激发机体的免疫机制，引起一个慢性排斥反应过程，导致移植段气管组织进行性坏死；软骨再生存在于移植后各个时间段，其再生程度与良好的血液循环有关；气管内支撑管的应用可防止肉芽组织增生堵塞管腔，从而保证气管管腔通畅。

However, the reason that LCD can't fully take the place of the tube is mainly on the performance of color and motion image. Though LCD can greatly improve the Color Saturation up to NTSC 105%, LCD is limited on reaction time and continue LCD light source, which create image shape shadows while the image moves due to photogene.

而液晶显示器目前无法完全取代映像管的地方就在於色彩及动态影像的表现，虽然发光二极体已可大大改善色彩饱和度到达NTSC 105%，但液晶显示器受限於液晶的反应时间及液晶显示光源表现为持续方式，使在动态影像表现上因人眼的视觉停留的因素导致影像移动的边界上产生阴影。

Because the temperature of coal volatile pyrogenation differs from the temperature of reduction of iron oxide by H2, H2 releases at the initial stages of reduction, and the reduction efficiency of hydrogen is very low.

由于煤中挥发分的热解析出温度与氢还原铁氧化物的还原温度不一致，氢在还原初期迅速放出，导致氢的还原作用率低；提高温度和加热速度可提高煤中氢的还原作用率和挥发分的利用率。

As the leader of a family group that can be as large as 30 individuals, they will lead their underlings to food, settle disputes within the clan, and fight to repel outside threats, particularly from other male gorillas, who will kill babies when seeking to usurp a silverback's group.
