Results The total aberrantion rate of chromosome is 26.7%(23/86);Compared the normal controls,in azoospermic patients,Serum FSH、LH levels increased,The rate of T/LH decreased.and there is a very significant difference(P%26lt;0.05);The resemble results is detected in different outcome in PESA.

结果摘要：86例无精子症患者中异常核型23例，占总例数26.7%；和正常对照组相比较，无精子症组血清FSH、LH升高，T/LH比值下降，差异有显著性(P%26lt；0.05)；PESA能抽吸到精子组比不能抽吸到精子组的FSH、LH偏高，T/LH下降(P%26lt；0.05)。

The results show that overpressure bench mark is well suited for describing anomaly distribution, and momentum bench mark can provide better measure for shockwave damage. Along with increasing of the branch deflexion angle, the primary tunnel momentum increases and the branch tunnel momentum decreases, and plane shockwave recover distance also increase but will not exceed six times equivalent diameter.

研究结果表明：超压准则适用于描述分布的不均性，而冲量准则能更好地衡量分叉巷道中冲击波的破坏作用；分叉角度的影响较大，随着分叉偏转角的增大，主巷道内冲量将增大而分巷道内冲量将减小，恢复"平面波"的距离也增大，但不超过6倍巷道等效直径。

the authors performed 3d photographic measurement on the technical moves of zhang wen-xiu as an excellent female hammer thrower in china to get relatively comprehensive body movement data by using two jvc3000 high-speed cameras, screened and analyzed the data by using spss software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sustainable accelerating power was not high.

BACKGROUND: Intermaxillary asymmetrical traction, a method routinely used in orthodontics to correct mandibular position and to adjust occluding relation, is conventionally employed as compensation treatment for adult jaw deformity.

背景：颌间不对称牵引是正畸中调整下颌位置和咬合关系的常规手段，常用于成人偏颌畸形的代偿性矫治。

Several sufficient conditions for judgement of the invariant set and the attraction for the equations are obtained by using the properties of nonnegative matrices and some analytical methods.

Nuclear DNA content analysis revealed that hybrid plants had different nuclear DNA content:higher,lower than the parental sum or equal to it.Contrast to the lower and equal hybrids,bigger amount of hybrids with higher DNA content had abnormal leaf,bad growth vigour and poor fertility.

结果表明：杂种形态变异广泛，多数呈中间类型，少数呈偏亲性状；杂种细胞DNA含量不一致，呈现大于、等于、小于双亲细胞DNA含量之和的类型；DNA含量大于双亲之和的杂种与DNA含量等于或小于双亲之和的杂种相比，有较高比例的材料叶型出现畸形和植株生长势弱，育性也更差。

The results above showed:(1) The cultivars of large-flowered chrysanthemum are widely distributed in Beijing area with plentiful floral types and floral colors;(2) The cultivars with the rare types and colors are urgent for protection;(3) Most of the quantitative characters obeys to the normal distribution,some important traits agreed with skewed distribution.The probability grading can assist quantitative character in establishing new grading standards;(4) Most of qualitative characters is asymmetrical in cultivars,which might be caused by unbalanced differentiation of characters or linkages coming from emphasis characters selection;(5) The floral characters are relatively stable and have comparably large influence on classification,the characters of stipule also have a certain degree of stability and can act as an reasonable supplement for cultivars classification,but the foliar characters have worse stability and can only be recognized as lower level criterion.(6) The genetic relationship among the Flat-petaled group,the Quilled-petal group and the Spoon-petaled group are closest,which followed by the Filiform-petal group because of long-term selection pressure for the specialization of the petal tip loved by most people.The Anemone-petal group has further genetic relationship with these four groups.(7) ISSR molecular marker detection indicates that the proportion of polymorphic loci of lardge-flowered chrysanthemum is higher,in which the Flat-petaled group has the highest genetic diversity level.

综合以上的研究结果表明：(1)北京地区现有大量大菊品种，且花型与花色较为丰富；(2)珍稀花型、花色品种亟需保护；(3)大部分数量性状是符合正态分布的，少数重点观赏性状迫于选择压力呈现偏态分布，概率分级法能够辅助大菊的数量性状建立新的分级标准；(4)大部分质量性状在品种群内的分布是不均匀的，可能是由菊花性状遗传分化的不均衡性或受到选育重点性状的连锁作用而造成的；(5)大菊花部性状相对稳定，对品种分类影响较大，其托叶部分也具有一定程度的稳定性，可以作为品种分类的合理补充，而叶部性状稳定性较差，在品种分类中应作为更次一级的分类依据；(6)平瓣类、管瓣类和匙瓣类的亲缘关系最近，畸瓣类品种花瓣先端特化受到人们的喜爱，长期的选择压力使其区别于3种基本瓣型，而这四种瓣型与桂瓣类在亲缘关系上较远；(7)ISSR分子标记检测表明：大菊品种多态性位点百分率较高，平瓣类品种的遗传分化最为丰富。

Results: Neonatal rats in hypoxic-ischemicgroup behaved restlessness, cyanosis, deep and rapid breath, astasia, lethargy, irritation and spasm; There were local pyknosis, fragmentation, dissymmetry, blur or disappearance of nucleoli, raritas of ground substance in left cerebral cortex; but there was no statistic significance in chinese traditional medicine group and sham group. The expression of HIF-1α mRNA in brain tissue of experimental group and chinese traditional medicine group were higher than that in sham group, especially chinese traditional medicine group at 3d; HIF-1α positive cells were found in cerebral cortex and hippocampus. There were more HIF-1α positive cells in experimental group and chinese traditional medicine group and mainly in vascular endothelial cells.
