前屈

Each of eight adult fresh cadaver specimen of lumbarsacral segmcnts was analyzed in four states: intact, L5S1 ALIF, L5S1 ALIF fixed with pedicle screw or fixed with translaminar facets screw, test and compare its range of motion in flexion, extension, lateral bending and axial rotation.

方法］ 采用新鲜腰椎标本8具，分别于完整状态、L5S1，前路植以Cage、L5S1，前路Cage分别行椎弓根钉固定及经椎板关节突螺钉固定下，测定前屈、后伸、侧弯及扭转运动下运动范围并进行比较。

Results: After the experiment female college student BMI,WHR,the peaceful heart rate,the vital capacity have the remarkable change;Physical quality targets and so on seat body anteflexion have the remarkable enhancement.

结果：实验后女大学生BMI、WHR、安静心率、肺活量有显著变化；坐位体前屈等身体素质指标有显著提高。

Methods Seven cadaveric spinal specimens were measured of neutrol zoneand range of motionin 6 movements including anteflexion,retroflexion,left and right lateral flexion,left and right axial rotation.

测试前屈、后伸、左侧弯、右侧弯、左旋转、右旋转的中性区(neutral zone，NZ)和运动范围(range of motion，ROM)。程序：完整状态；②骨折后状态；③椎体成形后；④3000次循环疲劳后。结果骨折后中性区和运动范围均明显增大。椎体成形后屈伸、侧弯、旋转在NZ及ROM均明显减少。

After initial strength and stiffness were determined, vertebral bodies were stabilized by bipedicular injection of 2, 4, 6, or 8ml ACPC and recompressed ibidem.

自8具尸体脊柱标本上截取24节胸腰段椎体，在前屈压缩载荷下造成骨折后，随机分成4组，分别经双侧椎弓根注入椎体2、4、6和8ml ACPC，再行前屈压缩。

The simple forward extensions– such as Adho MukhaVirasana, Adho Mukha Svastikasana, Janu Sirsasana, TriangMukhaikapada in Paschimottatanasana, Ardha Baddha Padma inPaschimottanasana, Marichyasana, Parsva Upavisthakonasana, AdhoMukha Upavisthakonasana done restfully checks the over bleeding,soothes the abdomen and makes the throbbing brain-cells rest.

和缓地练习简单的前屈动作-如下犬式， AdhoMukha Svastikasana，单腿背部伸式，单腿跪伸展式，半莲花单腿背部伸展式，圣哲玛里琪式，屈肘支撑的和上半身完全伸展的坐角式可以缓解流量过大，缓和下腹部不适及安抚大脑细胞。

ROM of the following construct fixation with Codman plates, Window plates with grafts and 1 mm shortened grafts were measured respectively, and the graft height were determined for each specimens by physical measurement of discectomy site.

将12例小牛颈椎标本随机分成两组，用生物力学测定仪测定正常颈椎C(下标 4/5)节段在前屈、后伸、左右侧屈、左右旋转时的三维运动范围，然后切除C(下标 4/5)椎间盘，制成损伤模型，测定植骨加钢板，植骨块缩短1mm加钢板固定后C(下标 4/5)节段的ROM，植骨块的长度根据测量椎间隙的高度而定。

The most dislodgement of cages were in rotation and the least were in flexion and extention.

Expended组在前屈、后伸、侧屈和旋转各种状态下ROM值均小于Interfix组和Telamon组，扩张式融合器最大拔出力分别比Telamon和Interfix高98.1%和32.4%。

The long-term outcomes of highly myopic patients with borderline corneal thickness after LASIK were less stable and predictable. The regression was probably related to the preoperative refraction, age, corneal thickness and keratometry readings.

高度近视薄角膜患者LASIK术后的远期稳定性较低，可预测性较差，术后屈光回退可能与术前屈光、年龄、角膜厚度和曲率的改变有关。

METHODS: The stability of intact specimens in flexion, extension, lateral bending and torsion was examined. A fracture model was created using dropping technique. The fracture model was instrumented with short-segment pedicular screw fixation (4-screw construct) or the intermediate screws structure (6-screw construct).

测量完整标本前屈-后伸、侧屈及旋转的稳定性后，通过重物撞击技术制造伤椎骨折模型，然后对每个标本行传统短节段椎弓根螺钉固定（4枚螺钉固定）及增加骨折椎椎弓根螺钉固定（6螺钉固定）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
