后颈

The second set of scenarios: Journal wear parts of liner with the first scenario, the first correction series water roll excircle and journal excircle parts machining rounding, trimming good necks confecting tight fit of steel casing.

第二套方案：轴颈磨损部位镶套同第一种方案，不后订正串火辊外方，并不兵轴颈外方部位加工方整，再在整理好的轴颈上配制不松打扰的钢套。

In order to reduce the axle journal of mechanical strength loss, grinding the shaft seating surface wear uneven Department just to Polish it, and then to the journal after Polish excircle size, choose a higher wear resistance ZQAl7-1.5-1.5 bronze, confecting a plain bearings again, replacing the original linear ball bearing.

为了减多轴颈的板滞强度吃亏，磨削的尺寸以轴颈表背磨损不服处恰好磨平为好，再以磨平后的轴颈外方尺寸为基准，采取耐磨性能较矮的ZQAl7-1.5-1.5青铜合金，从头配制一只滑动轴承，替代本来的曲线滚珠轴承。

RESULTS:①There was higher tensile stress at the ingual side of symphysis, inside of molar and outside of condyle under the impact of chin.②There was higher tensile stress at the lingual side of symphysis, inside of contralateral molar, outside of contralateral angle, outside of homolateral angle and inside of homolateral body under the impact of body.③There was higher tensile stress at the inside of angle, inside of homolateral condyle, lingual side of symphysis, outside of contralateral condyle and inside of homolateral molar under the impact of angle.

结果：①撞击颏部，其舌侧区，磨牙后区内侧面、髁状突颈外表面以及下颌角外表面具有较高的张应力；②撞击下颌体部，颏部舌侧区，对侧磨牙后区内侧面、对侧下颌角外表面、撞击侧下颌角外侧面、撞击侧体部内侧面具有较高的张应力；③撞击下颌角，其内侧面、撞击侧髁状突颈内侧面、颏部舌侧面、对侧髁状突颈外表面以及撞击侧磨牙后区内侧面具有较高的张应力。

To pay attention to carry out effective cardiopulmonary resuscitation, hemostasis by compression and deep vein intubation rapidly in the initial stage of emergency. The carotid shunt tube plays an important role in severe carotid injury and re-establishment process. We use external jugular vein to transplant and re-establish,which are rung with artificial blood vessels for the long distance carotid injury and achieved the best result. We expose as fully as possible for the hepatic venae and the posthepatic post caval injury,and adopt effective methods to stop bleeding and repair. The application of blood shunt pump could raise the success rate for those severe patients. The self-double vastransplantation with both ends being all trousers-style one opening solve some problems such as there are no suitable caliber self-transplantation blood vessels and the artificial blood vessels are easy to occur obliteration for long-term and so on for the great or middle blood vessels.We use improved Fogarty duct and anterograde intubation to eliminate thrombus could eliminate thrombus effectively and avoid accessory injury for the deep vein injury and extensive thrombosis.

抢救初期要注意进行有效的心肺复苏、压迫止血和快速进行深静脉插管；颈动脉转流管在严重颈动脉损伤重建过程中有重要作用；对长距离颈动脉损伤用颈外静脉移植外环包人造血管重建，可取得最佳效果；对肝静脉及肝后下腔静脉损伤，要充分暴露，采用有效方法止血和修复，对病情极危重的凶险性出血者，血液转流泵的应用可提高成功率；对大、中血管损伤，两端均为裤式单开口自体双血管移植，解决了无适宜口径自体移植血管和应用人造血管远期易闭塞等问题；对深静脉损伤并广泛血栓形成者，应用改进的Fogarty导管和顺行插管取栓法，可有效取栓并避免了副损伤。

The expression of AT2R gene can be regulated efficiently in vivo by local delivery of MSC with dual-stable expression of AT2R gene, thus reduces the formation of intimal hyperplasia.④AT2R gene can influence the expression of ECM and significantly promote the cellular apoptosis in the injury rat carotid artery.⑤These data demonstrate the clinical potential of AT2R regulatable expression to prevent restenosis after PCI.

研究结论：(1)与VSMC直接接触可以诱导MSC向血管成分细胞分化；(2)构建的Dox-on可调控的MSC细胞株诱导活性可靠，使外源AT2R基因的表达处于有效的主动控制下；(3)局部导入MSC不影响球囊损伤后大鼠颈动脉新生内膜增生；(4)由MSC介导的AT2R可调控表达受到Dox的良好调控，可有效抑制球囊损伤后大鼠颈动脉新生内膜增生；(5)AT2R影响血管损伤后修复时ECM成分的表达，并促进细胞凋亡的发生，可能是AT2R介导抑制新生内膜形成的机制。

Methods There were 12 cases, 10 of them were corpse specimens, the other 2 were clinic cases. Firstly we dissociate the contralateral C7 root from the intervertebral foramen to its divisions, secondly we set up a tunnel between the cone and the anterior scalenus, thirdly we moved the C7 root to the gap between the thyroid and the opposite carotid theca through the mentioned tunnel, then we dissociate the injured brachial plexus extensively, lastly we anastomose the contralateral C7 and the injured inferior trunk.

1.Preliminary studys on the carotid artery parameters Detected by Intracavitary Convex Array ProbePurpose and SignificanceFinal results of The North American Symptomatic Carotid Endarterectomy Trial and the MRC European Carotid Surgery Trial displayed that carotid artery must be observed intimately when stegnosis degree is higher than 50%and it must have an operation or interventional therapy in time when stegnosis degree is higher than 70%.

1、腔内凸阵超声探头检测颈动脉参数的初步研究目的和意义北美有症状颈动脉内膜剥脱试验(The North American Symptomatic CarotidEndarterectomy Trial NASCET)和欧洲颈动脉手术试验(European Carotid SurgeryTrial，ECST)研究结果显示，当颈动脉狭窄程度超过50%时要密切观察病情变化，当狭窄程度超过70%时要及时手术或介入治疗，治疗后可大幅降低脑梗死的发生率。

The left common carotid artery to external jugular vein shunt operations were performed on experimental rats to establish left to right shunt animal models. The common carotid artery and external carotid artery of the control group rats were isolated without connection.

将实验组(n=9)大鼠的左侧颈总动脉与颈外静脉用套管进行连接，对照组大鼠仅切开颈部皮肤分别分离颈总动脉和颈外静脉后缝合皮肤，不进行血管连接术。

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。
