The results showed that (1) the intervention of preoperative pain education resulted in statistically significant reductions of worst pain intensity after surgery in experimental group compared to control group,(2) subjects in the experimental group experienced statistically significant reductions of pain interference in general activity, mood, and sleep, compared to control subjects,(3) the misbeliefs about pain management were significantly improved after surgery in experimental group compared to control group,(4) no statistically significant differences were found in the score of satisfaction with pain management, or amount of analgesics between the two groups.

研究结果显示：（1）实验组接受手术前疼痛卫教介入措施后，手术后最剧烈疼痛强度低於控制组达统计上显著差异。（2）实验组手术后疼痛对日常生活、情绪及睡眠的干扰程度低於控制组，达统计上显著差异。（3）手术后实验组错误疼痛处置信念的改善程度，与控制组达统计上显著差异。（4）手术后的疼痛处置满意度及止痛药使用剂量，两组间无统计上显著差异。

Thiry-four medical-surgical wards were randomly separated into an experimental group and a control group in a medical center in central Taiwan by quasi-experimental design, and new staff nurses in experimental group were trained by the preceptors for three months, while the new straff nurses received without preceptors in a control group.

本研究目的在探讨临床护理辅导员制度对新进护理人员工作压力与离职意向之影响。以类实验设计法，将中部某医学中心的内外科病房以随机的方式分为实验组与对照组，实验组为有接受临床护理辅导员辅导之新进护理人员，对照组则无。

Results The experimental eyes quickly changed from pre-experimental hypermetropin to high myopia during the experimental period, and the severity of myopia and axial length increased relative to the period of form deprivation. The expression of VIPR2 mRNA and the levels decreased over time for both groups.

结果 实验组由实验前远视眼快速演变为高度近视眼，并随遮盖时间的延长、近视度数的加深，眼轴延长；两组眼球后壁均有VIPB2 mRNA的阳性表达；随着出生时间的延长，两组VIPR2 mRNA的表达均逐渐下降。

Seventy-seven male big rats of four to five months old with the weight of two hundred and eighty to three hundred and twenty grams were divided randomly into contrast group of zero week,contrast group of three weeks,contrast group of seven weeks,contrast group of eleven weeks,experimental group of three weeks,experimental group of seven weeks and experimental group of eleven w...

选用280～320g 4～5月龄wistar雄性大鼠44只，随机分为0周空白对照组11只，3周实验组11只，7周实验组11只，11周实验组11只，0周空白组于0周处死，解剖取大鼠股骨，以生理盐水浸湿的纱布包裹，置-20℃冰箱内保存备用。

Plackett-Burman experimental design and the uniform experimental design were used to select the main factors of the ball milling pretreatment of corn stalk. The experimental results were analyzed by data processing software and well-fitted regression equation was established. Effects of ball milling parameters, such as raw material diameter, speed, ratio of raw materials, grinding media and alternating time, on the enzymolysis were analyzed. The optimal parameters of ball milling pretreatment of the corn stalk were as follows: particle size of raw material of 0.5 mm, speed of 340 r/min, the raw material content of 3.4 g, the number of ball of 15 (Ф= 10.0 mm), alternating running time of 5 min.
