Management. Treatment of manifestations: Early diagnosis and treatment of RB and RB-related tumors can reduce morbidity and increase longevity; care is best provided by specialists from ophthalmology, pediatric ophthalmology, radiation oncology, oncology; treatment options depend on tumor stage, number of tumor foci (unifocal, unilateral multifocal, or bilateral), localization and size of the tumor within the eye, presence of vitreous seeding, and age of the child; treatment options may include enucleation, cryotherapy, photocoagulation, photochemistry, external beam radiation therapy, and radiation therapy using episcleral plaques; newer options include systemic chemotherapy combined with or followed by local therapy.

处理。 表征的治疗： RB 和 RB 相关肿瘤的早期诊断和治疗能减轻病状、延长存活时间；护理最好由眼科学、小儿眼科学、肿瘤学和放射肿瘤学等方面的专业医师来提供；治疗方案的选择取决于肿瘤阶段、病灶数量（单病灶、单侧多病灶或双侧病灶）、眼内肿瘤的位置和大小、玻璃体散布的存在与否以及患儿的年龄；治疗选项可能包括摘出术、冷冻疗法、光凝固术、光化学法、外照射放疗和用巩膜外斑块进行的放射治疗；新的治疗选项包括与局部治疗结合的或先行的系统化学疗法。

ABSTRACT: Silicoaluminophosphate molecular sieves are microporous crystals with the structure of SiO2、AlO2－、PO2+ tetrahedral units.The physical—chemical properties of SAPO are not only similar to silicoalumino zeolites but also similar to some aluminophosphate zeolites.SAPO is a novel class of catalytic materials which exhibit excellent shape—selectivity、thermal and hydrothermal stability.

摘 要：磷酸硅铝分子筛是由SiO2、AlO2－、PO2＋三种四面体单元构成的微孔型晶体，它的物化性质不仅类似于硅铝沸石，同时具有某些铝磷酸盐分子筛的特性，是一种具有优异的择形选择性以及热稳定性和湿热稳定性的新催化材料。

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.
