绿巨人继代培养与快繁的培养基筛选

在不同的生长调节剂组合的培养基上 ,取绿巨人的诱导芽进行继代培养 ,以产生大量的丛生芽 ,同时探讨了不同生长激素和浓度对丛生芽和不定根分化的影响 .结果表明MS +BA 0 5～ 1 +IBA/NAA 0 1 (mg/L)有较高的繁殖系数和成苗率以及成本低等优点 ;而BA 1～ 2 +NAA 0 2～ 0 5有利丛生芽分化 ,繁殖系数高 .     

小学骨干教师反思意识的调查与分析

反思对教师职业发展能起到推动和促进的作用。了解教师自己对反思的认识是培养教师反思能力的工作前提。本研究采用访谈法对北京市7所小学的28名骨干教师的反思意识进行了调查，发现当前小学骨干教师对反思的认识处于经验阶段，缺乏系统的理论认识。教师教育研究和培训应当为广大教师提供足够的反思理论知识，帮助教师澄清关于教学研究的观念，使反思能够在教育教学中充分发挥作用。

山羊抗小鹅瘟血清应用及制备

小鹅瘟在国内已广泛流行,雏鹅的预防和治疗以鹅抗小鹅瘟血清较为理想,但若用山羊抗小鹅瘟血清,则可获得大量的血清及长时间采血且降低成本,经笔者研制的山羊抗血清具琼扩试验效价达1:16;保护试验保护率达80—100%小范围区域试验保护率达95%。     

范梅南的教育机智思想对教师专业发展的启发

根据范梅南的教育学思想,教师的专业发展需要反思性教学,但更需要教育机智.教育机智是教师教育观念的生动体现,通过教育机智可以折射出教师的教育观.教师专业发展需要贯穿于整个教学过程的教育机智.     

Surgical management of gastric stump cancer： a report of 37 cases

Objective: To observe the clinicopathological characteristics of gastric stump cancer (GSC) and evaluate the benefits of radical surgery of GSC. Methods: The clinicopathological characteristics and postoperative survival time of 37 GSC patients who underwent surgery were investigated retrospectively. The survival time was compared according to the type of surgical pTMN stage. Survival curves were traced by using Kaplan-Meier methods. Results: Most GSC (32/37) was detected in patients who had received Billroth Ⅱ reconstruction after partial gastrectomy for benign gastric disease. The lesser curvature side and the suture line of anastomosis were the most frequent sites where GSC occurred (27/37). Differentiated adenocarcinoma was the dominant histopathological type (24/37). The postoperative 5-year survival rate of early stage GSC patients (n=9) was significantly higher than advanced stage GSC (n=12) (55.6% vs 16.5%, xL2=1 1.48, P＜0.01). Five-year survival rate of 21 GSC patients with radical resection were 75% (3/4) for stage Ⅰ, 60% (3/5) for stage Ⅱ, 14.2% (1/7) for stage Ⅲ, and 0% (0/5) for stage Ⅳ respectively.The median survival time of 21 GSC patients who underwent radical resection was longer than those undergoing palliative operation (43.0m vs 13.0m, xL2=36.31, P＜0.01), the median survival time of stage Ⅳ patients with radical resection was 23.8months. Conclusions: Without remote metastasis, radical resection for GSC is possible, and is an effective way to improve the prognosis of GSC. Even in stage Ⅳ GSC, radical resection can still prolong the survival time. It is necessary for the patients with benign gastric diseases who received partial gastrectomy to carry out the endoscopy follow-up, especially in patients with Billroth Ⅱ reconstruction procedure at 15-20 years.     

SiO2和聚乙烯醇双负载纳米ZnS对CO2的光催化还原反应

Nanosized photocatalyst ZnS particles supported on silica and polyvinyl alcohol was successfully prepared by complex transformation method. The photocatalytic reduction of CO2 was carried out in the presence of nanosized ZnS catalyst irradiated by a high-pressure mercury-vapor lamp to give the main products of formaldehyde and ethanol. The catalytic ability of ZnS characterized by the uptaken rate of CO2P volume in the reaction system depended upon the preparing conditions of nanosized ZnS catalysts. Decreasing the concentration of Na2S and increasing the molar ratio of oxygen in the PVA to Zn2 could result in the decreasing of the size of ZnS parti-
