According to the shape of head, the glandular hairs were divided into capitate and pehate glandular hairs.

根据腺毛头部形状可把腺毛分为盾状腺毛和头状腺毛，二者均发生得很早，它们的原始细胞都来源于原表皮，一般在茎尖第1和第2片叶原基的原表皮细胞以及茎的1～2节间原表皮细胞中开始发生。

The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

At present, regeneration system of cotyledons, hypocotyls, and stems, protoplasts and cotyledons codes have been established among Cucurbitaceae. There are several methods of transformation, such as agrobacteria -medidated genetic, particle gun, pollen tube passage, DNA soaking, ovary embryonary sac injection. Transgenic is tending to antivirotic and delayed maturity. Selection marker used often is NPT II.

目前，在葫芦科植物中已建立了子叶、茎尖、胚轴、茎段、原生质体和子叶节等的再生体系；用于遗传转化的方法有农杆菌介导法、基因枪法、花粉管通道法、DNA浸泡法等；用于转化的目的基因多为抗病毒病基因和延迟成熟的基因；NPTII基因为最常用的筛选标记基因。

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.
