目的探讨0.05%阿托品控制儿童近视眼进展的效果。设计前瞻性病例系列。研究对象64例6～13岁患近视眼的学龄儿童。方法将64例临床诊断的近视眼学龄儿童按照随机数字表法随机分为两组:试验组30例,每晚睡前点用0.05%阿托品滴眼液;对照组34例,不做任何治疗。观察1年,每月1次,检查视力、屈光状态和眼轴,比较两组的差异。主要指标屈光度、眼轴。结果阿托品治疗组患者近视眼进展(-0.28±0.26)D/年,显著低于对照组(-0.75±0.35)D/年(P=0.008)。阿托品治疗组眼轴增长(0.30±0.28)mm也低于对照组(0.65±0.61)mm(P=0.004)。阿托品治疗组患者无畏光、视物不清,眼压、裂隙灯及眼底检查无异常。结论在至少1年规律应用的情况下,0.05%阿托品是控制多数学龄儿童近视眼进展的有效药物。

采用高温固相法制备一系列Sr_2SiO_4∶Eu0.01,Dy_x(x=0.000 1,0.002 5,0.005,0.01)应力发光材料,研究了不同掺杂浓度下,Sr_2SiO_4∶Eu,Dy的光致发光和应力发光性质。研究结果表明在掺杂Dy^(3+)浓度较低时,样品同时存在α和β两种相,当掺杂Dy^(3+)浓度增加时,则出现β到α的相转变。由于Eu^(2+)占据Sr^(2+)格位的不同,样品在蓝光区486nm(Sr1)和绿光区530nm(Sr2)有两个峰存在。而应力发光光谱与余辉光谱类似,均只呈现出530nm的发光,这说明二者的发光来源于占据Sr_2格位的Eu^(2+),都是通过改变陷阱的浓度实现发光性能的变化,但Sr_2SiO_4∶Eu,Dy的应力发光强度的变化还与其结构改变有关。同时,Sr_2SiO_4∶Eu,Dy应力发光强度与所施加的力之间呈良好的线性关系,并且可用眼睛观察到明显的黄色应力发光,这为应力发光传感器准确检测物体所受应力提供依据。结合余辉、热释以及应力发光性质,推测Sr_2SiO_4∶Eu,Dy的应力发光机制应是压电产生的电致发光。

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus Tanbo-plucking the trigger points for scapulohumeral periarthritis (SP). Methods:A total of 80 patients with SP were randomized into an observation group and an EA group by the random number table, with 40 cases in each group. The EA group was treated with EA therapy, and the observation group was treated with EA therapy plus Tanbo-plucking the trigger points. After treatment, the visual analog scale (VAS) and Melle scores of the two groups were compared to evaluate the improvement of shoulder pain and functional activity, and meanwhile the clinical efficacy was observed. Results: After treatment, the total effective rate of the observation group was 95.0% and the cure and markedly effective rate was 72.5%. The total effective rate of the EA group was 87.5% and the cure and markedly effective rate was 42.5%. There was no significant difference in the total effective rate between the two groups (P>0.05). The cure and markedly effective rate of the observation group was higher than that of the EA group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the intra-group differences in VAS and Melle scores of both groups were statistically significant (bothP<0.001). The inter-group differences in the changes of the VAS and Melle scores after treatment were statistically significant (bothP<0.001). Conclusion: EA plus Tanbo-plucking the trigger points has a better curative effect than EA therapy alone in the treatment of SP.

主体间性理论对城乡教育一体化具有重要的方法论意义,城乡教育之间是主体间性的关系。从主体间性理论来看,城乡教育共同体的价值取向应该"和而不同",既有教育公平与教育现代化的共同愿景,也尊重城乡教育的不同特质。城乡教育主体间性的实施策略为:理性分析城乡教育一体化的要素,重构城乡教育一体的文化机制,及时调控城乡学校互动的微观样态,合理协调共性与个性的关系。
