分别于照光5min后即刻、照光10min后即刻、照光20min后即刻、照光20min后第1天、照光20min后第3天分别取6只鸡冠行肉眼、活体显微镜、激光多普勒血流图、光镜和电镜检查，观察鸡冠激光照射处皮肤微循环结构和血流状态的动态变化。

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。

In our study, we also observed the different influence between TTB-USA and RFCA on blood coagulable states (by examining the change ofα-granule membrane protein、Tissue type plasminogen activatior、Plasmingen activator inhibitor-1)、 endothelium function (by examining the change of endothelin、nitric oxide) and myocardial injury (by examining the change of creatine kinase、MB isoenzy of creatine kinase and cardiac troponin T).

为观察超声消融与射频消融对血凝状态、内皮功能及心肌损伤的影响，进一步对超声消融的安全性进行评价，我们在插管前、插管后、消融后即刻、消融后30min及48小时5次抽静脉血，分别测定血小板α-颗粒糖蛋白(GMP-140)阳性表达活化血小板百分率、内皮素、一氧化氮、组织型纤溶酶原激活剂及纤溶酶原激活剂抑制物-1(PAI-1)的变化；于消融前、消融后即刻、2hr、8hr、24hr、48hr、72hr抽取静脉血，检测肌酸激酶、肌酸激酶MB同工酶及心肌肌钙蛋白T的变化。

Clinical results showed that posterior screw fixation on atlas could relieve spinal and neural oppression immediately,improve clinical symptoms,have good immediate postoperative stability,keep the movement of occipitocervical region,and showed its advantages in very high successful fusion rate,and very few instrument failure,morbidity and complications.

临床结果显示：后路寰椎螺钉固定技术能即刻解除脊髓神经压迫、缓解症状，有较好的即刻稳定性，保留枕颈间的运动功能，并且有融合率极高，断钉率、疾病复发以及术后并发症极少等优越性。

The RF electricity of ice adopts radio frequency technique of the RF dual pole. The frequency can make the water element of the cell which at the certain depth shake at a high speed, it can produce the quantity of heat at 45-60℃ through the quick circumvolved friction. Because the collagen fibre is shrinked, the wrinkle can be tighted. Then the light pyrolysis stimulates collagen and elasticity fibre to become more and arrange once again so as to reach the function of dispelling wrinkle and shrinking pore.

冰电除皱系统采用RF双极射频技术，发射的频率可以在皮下的特定深度内使细胞内的水分子产生高速震动，通过这种高速的旋转摩擦从而产生热量45-60℃，胶原纤维收缩，即刻松弛的皮肤、皱纹被拉紧，随后，真皮层中产生的热效应使胶原增生、重新排列、数量增加，同时修复老化受损的胶原，达到即刻紧肤、长效除皱抗衰老的效果。
