RESULTS: FGFR1-positive chondrocytes were abundant in the maturative layer and hypertrophic layer, but only few FGFR1-positive chondrocytes were found in the proliferative layer. In the control group, the expression of FGFR1 increased from 6-week-old to 10-week-old rats, and then decreased and went stable. In both young and adult group, the expression of FGFR1 in the experimental group was significantly lower at 4, 6 weeks and higher at 8 weeks than that in the control group, especially in the young group (P.05). But no difference was found between the experimental group and the control group at 2 weeks in both groups. CONCLUSION: FGFR1 may play an important role in the remodling of condylar cartilage induced by occlusal disorders.

结果：FGFR1主要表达在大鼠髁突软骨过渡层和肥大层，增殖层很少；正常组大鼠髁突软骨从6周龄到10周龄FGFR1表达逐渐增强，10周龄后降低，并保持在一个稳定水平；成年组和幼年组实验4、6周时FGFR1的表达均显著低于对照组，实验8周时的表达高于对照组(P.05)，幼年组尤为明显，实验2周组与对照组无显著差异。

To study the lethal effect of high power near infrared diode laser on Locust Nymphae. Oedaleus asiaticus B. Bienko Nymphae that are the third age or before the third age and after the third age were irradiated aiming at the head in different time and power density by the power of 2W and the wavelength of 808nm diode laser. The death-ratio was observed especially after irradiation, five hours after irradiation and 20 o clock the next day after irradiation.
