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。

The clinical data of 15 cases with chronic dacryocystisis accepted dacryocystorhinostomy through nasal cavity and lacrimal sac were analyzed retrospectively.

回顾分析经鼻内窥镜下鼻腔泪囊吻合术治疗慢性泪囊炎15例的临床资料。

The dacryocystorhinostomy was operated by the same experienced doctor.During the operation putting methylcellulose into the lacrimal sac before cut.

其中手术的关键在于泪囊鼻黏膜瓣的制作及吻合，形成新的黏膜通道，而达到治愈的目的，这样泪囊黏膜瓣的制作亦较为重要。

Abstract］ Objective To operate the dacryocystorhinostomy for the chronic dacryocystitis,during the operation putting methylcellulose into the lacrimal sac that has been cut before.

摘要］ 目的通过对慢性泪囊炎患者施行泪囊鼻腔吻合术，手术中在制作泪囊鼻黏膜瓣前应用甲基纤维素，评价其在提高泪囊鼻腔吻合术成功率的作用。

Making a valve on the lacrimal sac will be more accurate,perfect and raise the successful rate on the dacryocystorhinostomy.

甲基纤维素黏度高、弹性好，在泪囊鼻腔吻合术中制作泪囊黏膜瓣前，将甲基纤维素注入泪囊内，泪囊充盈，使泪囊黏膜瓣的制作更准确、完善，提高了手术成功率。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
