RESULTS: The relative levels of COX2 mRNA as well as the contents of PGE2 and cAMP were elevated after fracture, and were significantly higher in study group than those in control group at 3 and 4 weeks postoperatively. Histological observation revealed that the mineralization of cartilage matrix, the endochondral bone formation and the callus remodelling took place earlier in study group.

结果：环氧化酶2(COX2) mRNA的表达量以及PGE2和cAMP的含量均较骨折前显著上升，且实验组在术后3~4 wk时以上指标明显高于对照组，组织学结果则显示实验组骨折间隙内软骨内成骨和编织骨向板层骨的改建均领先于对照组。

活血化瘀汤能通过促进骨折大鼠Ⅰ型胶原、骨钙素、TGF-β1 mRNA及蛋白的表达，促进软骨内成骨。

Suitable operation combination, bone shaft lengthening nearing bone end, keeping endosteal cortical bone osteotomy, and a continual lengthening of 1.0 mm.d- for adults and 1.5～2.0 mm.d-1 for children can get ideal limb length, quality and fast callus development and satisfactory joint function.

实施靠近骨端的骨干延长，保留内骨膜的皮质骨截骨，成人每天1.0 mm、儿童每天1.5～2.0 mm的连续延长，可获得理想的肢体长度、良好的骨痂生长速度和质量以及满意的关节功能。

Spikelets with 1 floret, small, often gaping, without rachilla extension; rachilla disarticulating above glumes; glumes persistent, longer than floret, subequal or lower a little longer, membranous, 1-veined, apex subacute to acuminate; floret callus glabrous or shortly pilose; lemma oblong to elliptic, thinner than glumes, often hyaline, 5-veined, rounded on back, glabrous or hairy, lateral veins sometimes excurrent, awnless or awned from back, apex truncate or toothed; awn usually geniculate, sometimes weakly so or straight when short; palea shorter than lemma, sometimes very small.

小穗具1小花，小，张口的通常，没有小穗轴扩展；高于颖片脱节的小穗轴；宿存的颖片，长于小花，下部的近等长的或稍长些，膜质，1脉，先端近尖的到渐尖；无毛的小花结茧或者具短柔毛；外稃长方形到椭圆形，比颖片瘦，经常透明，5脉，通常膝曲，有时身体虚弱的芒或者直接，缺乏；内稃短于外稃，有时很小。

The frequency of callus induction was different when the same kind of Festuca arundinacea seeds was cultivated in MS medium supplemented w ith different types of and different concentrations of hormones.

通过愈伤组织的继代和分化培养，诱导出丛生芽，分化培养基以MS + 4mg L 2 ，4 D + 0 。2mg LKT为最佳，初步建立起高羊茅的植株再生体系

A modified Galanthus nivalis agglutinin gene was introduced into the genome of main cultivar 'Ningqi No.1' of Lycium bararum in vitro with explants of leaf disks mediated by Agrobacterium tumefaciens. Several factors affecting transformation efficiencies were studied based on induction rate of resistant callus. An effective system for genetic transformation of Lycium bararum was set up, and 70 kanamycinresistant transformants were obtained.

为了解决枸杞蚜虫侵害的难题，以宁夏枸杞主栽品种&宁杞1号&叶片为外植体，通过农杆菌介导的转化方法，将改造后的雪花莲凝集素GNA基因转入枸杞，以抗性愈伤组织诱导率作为转化效率的指标，对影响转化效率的因素进行了研究，初步建立了转化频率较高的转化系统。

The best explant in the culture was brown leaf,and the explant sterilized in 0.1% aqueous mercuric chloride for 5min has the best effect;At the initial stage in induction,3% glucosan have the best effect following with 1% glucosan+2%sucrose are optimum in the process of culturing;the optimum culture medium is 1/2MS; the preferable medium of callus is 1/2MS+ KT(0.1mg/L)+6-BA(0.05mg/L)+2.4-D(0.4mg/l);differentiation1/2MS+6-BA(0.3mg/l)+NAA0.2+KT(0.05mg/l);and the preferable medium of rooting is :1/2MS+NAA(0.05mg/L).
