医科院校师生对考试现状看法的调查与分析

医科院校的考试主要是学科考试。调查显示，教师和学生对目前的学科考试模式评价均不高，存在的最主要弊端是考试方法单一，考试管理不够科学、严谨，考风不好；认为作弊的主要原因在于学生自己学习不努力、社会风气影响以及学校对教师和学生要求不够严格。因此，要搞好考试改革，提高考试质量，必须着重从改革考试方法、加强考试管理的改革与研究、整顿考风、制定科学的成绩评定方法、加强能力考核、实施教考分离等方面进行探索与实践。     

医科院校学科考试方法的调查与思考

学科考试方法的改革是当前医科院校教学改革的一项重要内容.调查表明,教师和学生双方对考试方法的意见是比较客观的.考试方法的改革必须根据考试目的、内容、规模、对象以及课程教学特点等多方面因素,科学选择,灵活运用.

MDS患者P15基因高度甲基化的研究

目的 :研究P15基因通过甲基化失活在骨髓增生异常综合征 (MDS)发病中的作用。方法 :用甲基化敏感的限制性核酸内切酶消化 ,结合聚合酶链反应 (PCR)技术。结果 :2 0例MDS患者中发现有 9例 (45 % )存在P15基因高度甲基化 ,且多为高危MDS (RAEB、RAEB_t) (P <0 .0 5 )。结论 :P15基因可通过甲基化而失活 ,可能与部分MDS的发生及发展有关。     

泪道内镜下治疗泪道阻塞性疾病的初步观察

Objective To evaluate the therapeutic efficacy of lacrimal endoscope treatment for lacrimal passage obstruction, and to compare the effectiveness of endoscopically controlled laser surgery and micro-drill surgery for lacrimal passage obstruction. Methods It was a prospective random controlled trial. Eighty nine patients (104 eyes) with lacrimal passage obstruction, including presaccal canalicular obstruction (PSCO) and nasolacrimal duct obstruction (NLDO), were collected from September 2006 to December 2006 in Department of Ophthalmology, Union Hospital of Tongji Medical College, Huazhong University of Science and Technology. Patients were examined by endoscopy of the lacrimal drainage system under local anesthesia to detect the obstruction and changes of lacrimal mucous membrane. The obstructions were treated with laser or microdrill. Irrigation was performed to prove the recanalization of the lacrimal passage followed by injected ointment with 0.3% tobramycin and 0.1% dexamethasone into the lacrimal passage. All patients were followed up after the operation for 9-12 months. The difference between the laser and the microdrill treatment was observed. Chi-square test was used to evaluate the curative effect and complications differences between these two groups. Results The obstruction scene in the lacrimal passage of 89 patients could be observed effectively. All obstructions (104/104 eyes) were eliminated after the operation. Through the follow-up, the cure rate reached 78.85% (82/104 eyes). The cure rate of PSCO group and NLDO group, reached 77.78% (42/54 eyes) and 80.00% (40/50 eyes), respectively (χ2=0.077,P=0.782). The cure rate of laser group and micro-drill group, was 80.43% (37/46 eyes) and 77.59% (45/58 eyes), respectively (χ2=0.125,P=0.724). The cure rate of laser treatment was 89.66% (26/29 eyes) in the PSCO group and 64.71% (11/17 eyes) in the NLDO group (P=0.040). The cure rate of micro-drill treatment was 64.00% (16/25 eyes) in the PSCO group and 87.88% (29/33 eyes) in the NLDO group (χ2=4.664,P=0.031). Hemorrhage and palpebral edema occurred in 10.87% (5/46 eyes) and 4.35% (2/46 eyes) after laser treatment, respectively. Percentage of hemorrhage and palpebral edema after the micro-drill treatment was 55.17% (32/58 eyes) (compared to the laser group, χ2=21.969,P=0.000) and 6.90% (4/58 eyes) (compared to the laser group, χ2=0.017 ,P=0.896). Conclusions Lacrimal passage obstruction can be observed and treated directly through the endoscopy of lacrimal drainage system. Choosing an appropriate surgical procedure according to the locations of the obstruction can be helpful for improving the effectiveness of the operation.
