Objective To discuss the application of Mitomycin C under safe effective concentration in excision of pterygium with conjunctival flap autograft and observe the efficiency on the prevention of primary pterygium from relapse.Methods Incisions of 64 primary pterygia in 54 cases were performed with conjunctival flap autograft. MMC was used in operation or post-operation. After 5 to 12 months of follow-up, a comparison was made on the relapse of primary pterygium between the above-mentioned group and another 33 pterygia in 27 cases that only performed the similar operation without the application of MMC.

目的 在安全有效浓度下，将丝裂霉素C应用于翼状胬肉切除联合自体结膜瓣移植术中，观察对翼状胬肉复发的防治效果方法对54例64眼原发性翼状胬肉者施行显微镜下胬肉切除带蒂结膜瓣移植转位移植联合术中或术后丝裂霉素C的应用，经5～12 月的随访，以单纯手术组（27例33眼）原发性翼状胬肉术后复发情况作对比分析。

Results ①Of 82% OSAHS patients' sleep indices were normal after the oral appliance therapy;②Compared to the control group,the patients with OSAHS had narrower upper-posterior airway volume and shorter distance from tip of the uvula to the posterior pharyngeal wall and lower positioned hyoid bone and shorter tongue before treatment;③Compared to before treatment,the OSAHS patients after therapy had lower positioned and shorter and flatter tongue,the upper hyoid bone,more anterior and downward mandibular and wider upper-posterior airway volume.In comparison to control subjects,the indices were almost the same except for the lower positioned tongue.

结果 ①82%患者治疗后睡眠指标达正常标准；②与配对组相比OSAHS患者上气道后间隙及悬雍垂尖至咽后壁距较窄，舌骨至下颌平面距较大，舌较短；③戴入口腔矫治器后患者舌体下降，舌变短而平坦，舌骨上移，下颌骨前下方移位，上气道后间隙扩大，与配对组比较，除舌体下移外其它测量项目值差异无显著性。

Results According to the score criteria of IBS curve patterns,when IBS curve score were 1 or 2,the magnitude of VIB nd CVIB% were between controlled groups and infracted groups,and comparison to the two there were significant difference,it is ischemic myocardium or viable myocardium.The segments of IBS curve score≤2 were 43.6%（17/39）,there weren's statistical difference between its IBS% and onesof infracted group.

评为1分及2分的心肌节段即IBS曲线形态评分≤2分者，其IBS周期变异幅度、IBS周期变异率%界于对照组和梗死组之间，且与该二者比较差异有显著性，考虑其为缺血心肌即存活心肌，占43.6%（17/39），但其IBS%与梗死组之间比较无统计学差异。

The results showed that (1) COX-2 mRNA and protein existed in the mature male rat testis. COX-2 was localized in spermatocytes by immunohistochemistry.(2) COX-2 also existed in adult man testis. COX-2 protein was positively stained in spermatocytes and Leydig cells.(3) 2 weeks after administration of rofecoxib, the level of testosterone in the whole testis reached its lower values, being only 50% of control values. However, testosterone level recovered during 4 weeks. After such treatment, histologic examination of these testes showed atrophy of the seminiferous tubules and maturation arrest of spermatogenesis.(4) 2 weeks post-EDS, expression of COX-2 decreased significantly (P.005), in comparison with vehicle-treatment control. 4 weeks after treatment, a new generation of fetal like Leydig cells repopulated in the testicular interstitium resulting in COX-2 expression partially recovered. Although the expression of COX-2 mRNA and protein are enhanced at 8th week after using external testosterone, it wasn't significant higher than control group.

实验研究证明：(1)正常成年雄性大鼠睾丸组织中COX-2在mRNA和蛋白质水平均存在表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞；正常成年男性睾丸组织中同样存在COX-2表达，免疫组织化学结果显示COX-2定位于曲细精管内的生精细胞和Leydig细胞；(2)服用特异性COX-2酶抑制剂rofecoxib 2周后，实验组大鼠睾丸组织内睾酮的含量减少，为正常对照组的50％；持续用药4周后睾丸组织内睾酮浓度逐渐恢复至正常水平；COX-2酶活性降低后病理组织切片显示睾丸内曲细精管萎缩，生精紊乱，持续用药4周时影响最明显；(3)注射特异性Leydig细胞杀灭剂EDS 2周后，实验组大鼠睾丸组织内睾酮浓度降至极低水平时，COX-2的蛋白和基因表达水平也显著低于正常空白对照组（P.005）；使用EDS后第4周，睾丸组织中的睾酮浓度逐渐回升，同样组织中COX-2蛋白表达和mRNA表达水平也相应提高接近正常水平；使用EDS后4周开始给予外源性睾酮，6周和8周时COX-2表达水平的绝对值虽有提高，但与正常大鼠空白对照组比较并无显著性差异，说明外源性雄激素刺激睾丸合成COX-2的作用并不明显。
