In comparison with no screening program, the ICER for the vision screening program for preschool children aged 4-6, was found to be less than the threshold proposed from the World Health Organization and therefore vision screening program for preschool children aged 4-6 could be considered cost-effective.

本研究结果显示，若执行4-6岁弱视筛检计画，每多得到一单位品质校正人年所需要多花的成本均低於世界卫生组织所建议之标准阈值。本研究结果显示执行4-6岁学龄前儿童弱视筛检是具有成本效之策。

Ninety seven spores or sporocarps of VAMF were wet sieved from the rhizosphere soil of mycorrhized pteridophytes, from which 25 VAMF species which belonged to the genera of Acaulospora, Gigaspora, Glomus, Sclerocystis and Scutellospora respectively were identified, and the taxonomic characters of the 25 species were described. The Glomus fungi were the dominant VAMF in the rhizosphere soil of pteridophytes, they took up 44% in the identified 25 VAMF (11 species belong to Glomus); the fungi in Acaulospora and Sclerocystis in the next place, they took up 24% and 16% respectively in the identified VAMF; the fungi in the other genera took up 16%. In terms of the relationships of pteridophytes and the VAMF isolated from their rhizosphere soil, there was no specifity between the VAMF and their host.

从具有VA菌根的蕨类植物对应的根际土壤中用湿筛法筛取了97份VA菌根真菌的孢子或孢子果，从中鉴定出了分属于无醒囊霉属、巨孢囊霉属、球囊霉属、硬囊霉属和盾孢囊霉属的VA菌根真菌25种，并对这25种真菌的分类学特征进行了描述；球囊霉属真菌是蕨类植物根际土壤中的优势类群，已鉴定的25种真菌中，有11种属球囊霉属真菌，占44%，其次是无梗囊霉属和硬囊霉属真菌，分别占24%和16%，其他属的VA菌根真菌占16%，从分离鉴定的蕨类植物根际土壤中的VA菌根真菌与蕨类植物的关系看，VA菌根真菌与蕨类植物之间无明显的专一性。

Maternal and perinatal risk factors of occurrence of R OP were analyzed. Results In the 639 infants who had been scre ened in the 6 ho spitals, ROP was detected in 69 (10.8%), in whom 23 infants (39 eyes)(3.6%) had type 1 ROP and underwent photocoagulation.

结果 六家医院NICU符合筛查标准并完成ROP筛查的患儿639例中，发现ROP患儿69例，占10.8％。69例ROP患儿中，达到阈值或阈值前病变1型需要进行眼底激光光凝治疗者23例39只眼，占3.6％。
