政治教学中启发式教学的运用

叶圣陶先生说过：“教师之为教，不在全盘授予，而在相机诱导”，“所谓教师之主导作用，在于引导启迪，使学生自奋其力，自致其知，非谓教师滔滔讲说，学生默默聆受”。意思就要求教师发挥主导作用（启），充分调动学生的学习主动性、积极性（发），使学生通过自己的学习和思考来提高分析问题的能力和认识水平，这种教学方法就是启发式教学。启发式教学，是一种积傲的双向的教学方法。

Implanting hydroxyapatite-coated porous titanium with bone morphogenetic protein-2 and hyaluronic acid into distal femoral metaphysis of rabbits

Objective： To assess the osseointegration capability of hydroxyapatite-coated porous titanium with bone morphogenetic protein-2 （BMP-2） and hyaluronic acid to repair defects in the distal femur metaphysis in rabbits.
Methods： Porous titanium implants were made by sintering titanium powder at high temperature, which were coated with hydroxyapatite by alkali and heat treatment and with BMP-2 combined with bone regeneration materials. And hyaluronic acid was further used as delivery system to prolong the effect of BMP-2. The implants were inserted into the metaphysis of the distal femur of rabbits. The animals were killed at 6, 12 and 24 weeks to accomplish histological and biomechanical analyses.
Results： According to the result of histological analysis, the osseointegration in BMP-2 group was better than that of the HA-coated porous titanium group. In push-out test, all the samples had bigger shear stress as time passed by. There was statistical difference between the two groups in 6 and 12 weeks but not in 24 weeks.
Conclusion： Hydroxyapatite-coated porous titanium with BMP-2 and hyaluronic acid has a good effect in repairing defects of distal fumur in rabbits, which is a fine biotechnology for future clinical application.     

1例假性球麻痹患者误咽窒息的教训

球麻痹即延髓麻痹，是常见的咽喉肌和舌肌麻痹综合征，表现为声音嘶哑、饮水呛咳、吞咽困难和构青障碍等一组症状．有真性和假性之分。若足延髓运动神经核或吞咽神经、迷走神经和舌下神经等下运动神经元损害所致为真性球麻痹，如果是双侧大脑皮质上运动神经元或皮质延髓束损害所致则为假性球麻痹。二者最主要的区别是假性球麻痹患者咽部感觉和咽反射存在，无舌肌萎缩。此类患者因有吞咽困难、饮水呛咳，稍不注意就会出现误咽导致窒息，后果非常严重。为了保证患者的营养，常规上鼻胃管行鼻饲喂养，
