The experimental results are shown that the microstructure of QT600-3 by CO_2 laser quenching is Aphanitic Martensite+Graphite,and residual stresses are all compressive,which is above 120 MPa,they increase with laser power.

结果表明：经CO_2激光淬火后QT600-3的显微组织为隐晶马氏体+石墨，残余应力均为压应力，其值在120 MPa以上，且随着功率的增大而增加；相变层深度随着扫描速率和光斑直径的增加而减小，且随着功率的增大而增加；激光淬火后的材料组织结构比较均匀，有利于提高凸轮轴的使用寿命。

Results: The colporrhagia stopped within 3 days in the group treated with MPA and 83.33% abnormal echo with less than 1cm could not be seen by the ultrasonography after the withdrawal bleeding.

结果：应用安宫黄体酮后3d内阴道出血停止，撤退出血后B超示宫腔内1cm以下的异常回声消失率达83.33%，与对照组比较差异有显著意义。

The principles of the operative technique are to (1) restore coronoid stability throughfracture fixation (type-II or III fractures7) or through anterior capsular repair (a type-I fracture),(2) restore radial head stability through fracture fixation or replacement with a metal prosthesis,(3) restore lateral stability through repair of the lateral collateral ligament complex and associated so-called secondary constraints such as the common extensor origin and/or the posterolateral capsule,(4) repair the medial collateral ligament in patients with residual posterior instability, and (5) apply a hinged external fixator when conventional repair does not establish sufficient joint stability to allow early motion.

外科手术的原则是：①通过骨折固定(2型骨折或3型骨折)或者经前方关节囊修复(1型骨折)恢复冠状突的稳定。②通过骨折固定或假体置换恢复桡骨头的稳定性③通过修复侧副韧带以及相关的所谓的次要限制如伸肌群起点和后外侧关节囊。④残余的后侧不稳，修复内侧副韧带⑤当传统的修复方法不能建立有效的关节稳定以便允许早期活动时，可以应用外固定器。

Objective To observe the production and removal of photo-product, cyclobutane pyrimidine dimers, in HaCaT cells induced by UVB irradiation and intervention effect of ligustrazine, and to investigate its photo-protective mechanisms on HaCaT cells damaged from UVB irradiation.

目的观察中波紫外线辐射后永生化角质形成细胞株中光产物环丁烷嘧啶二聚体的产生和清除情况，观察川芎嗪对UVB辐射后细胞光产物的影响并探讨其保护作用机制。

Ephrin-A5 is expressed in high level in the body of neuron and cytodendrite during 4 weeks after cerebral infarction, suggesting that ephrin-A5 may be one of the primary factors responsible for the failure of axon projection after cerebral infarction.

脑梗死后ephrin-A5在梗死灶周神经元胞体、树突中持续高水平表达，它可能是造成成年哺乳动物中枢神经系统损伤后神经轴突再投射障碍的重要原因之一。

Based on physical sign and pathological change,GMC is divided into A,B,C three types.Twenty patients with 40 sides who were diagnosed as having GMC were treated with Ye' s detacher with microtrauma . The therapeutic effectiveness comparison was made between microtrauma treatment and the little wound treatment via posterior greater trochanter by the same standard of therapeutic evaluation.

根据体征及病理变化，将GMC分为A、B、C三型后，采用特制叶氏剥离刀对20例40侧各型GMC患者进行微创治疗，然后按同一疗效评价标准与大转子后小切口治疗GMC的效果相比较。

The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

After the fusion-treated protoplasts were cultured in BH3/EME medium for 2 days, pollen tube growing protoplasts were observed.
