Among various fruit-growing positions, compared with the abnormal lateral fruitlets, the normal central and lateral fmitlets had higher fresh weight, dry weight and total Ca, Mg, K content of single fruit, and bigger diameter, more vascular bundles, thicker xylem and bigger phloem vascular bundles area of pedicel, but lower content of Ca, Mg in pedicels.

结果表明，随幼果的发育，单个幼果重量和Ca、Mg、K含量呈增加趋势；与发育不正常的边果相比，发育正常的中心果和边果的鲜重、干重、果柄直径、维管束数目、木质部厚度、韧皮部维管束面积和单果Ca、Mg、K总含量较高，而以干重为单位的果柄Ca、Mg含量较低。

The vascular bundle ceils stemmed from ground meristem, belonging to ground tissue and differing from vascular bundle sheaths in origin.

而维管束鞘细胞则来源于基本分生组织，属于基本组织的范畴，与维管束不同源。

METHODS: Sixty two cases of specimens collected in operation were studied by in situ RT PCR, of which 50 cases were hemangioma: 26 cases proliferating hemangioma and 24 cases involuting hemangioma, and 12 cases were venous vascular malformation. The expression of Ang2 mRNA and Tie2 mRNA in hemangiomas and venous vascular malformation were detected by in situ RT PCR.

采用原位RT PCR方法，对临床收集的62例手术切除的先天性皮肤血管标本（其中增生期血管瘤26例，消退期血管瘤24例，静脉型血管畸形12例）进行Ang2 mRNA， Tie2 mRNA表达水平的检测。

Two cases of specimens collected in operation were studied by in situ RT????PCR, of which 50 cases were hemangioma: 26 cases proliferating hemangioma and 24 cases involuting hemangioma, and 12 cases were venous vascular malformation. The expression of Ang2 mRNA and Tie2 mRNA in hemangiomas and venous vascular malformation were detected by in situ RT????

PCR方法，对临床收集的62例手术切除的先天性皮肤血管标本（其中增生期血管瘤26例，消退期血管瘤24例，静脉型血管畸形12例）进行Ang2 mRNA， Tie2 mRNA表达水平的检测。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

PCR. RESULTS: The results showed that Ang2 mRNA and Tie2 mRNA were expressed in proliferating hemangioma, involuting hemangioma and venous vascular malformation, but the expression of Ang2 mRNA and Tie2 mRNA in venous vascular malformation was lower than that in proliferating and involuting hemangioma.

结果：增生期、消退期血管瘤及静脉型血管畸形均有Ang2 mRNA， Tie2 mRNA的阳性信号，但是三者阳性信号强弱有显著性差异

Firstly, the leaf vascular bundle turned to single vascular bundle, and becoming concrescence, the mid-part presented the pith-like parenchyma tissue, the concrescence of the different needle in one bundle formed the typical structure of the short shoot.

首先针叶中的维管束全部转变为单维管束，进而针叶基部逐渐愈合，中央部位逐渐出现类似髓部的薄壁组织，不同针叶的维管束逐渐愈合，最终形成完全具备枝条的典型结构。
