Objective To investigate the effect of interleukin-10 （IL-10） gene transfer on expression of CD44, selectin-E, lymphocyte function associated antigen-1 （LFA-1）, vascular cell adhesion molecule-1 （VCAM-1） in mice heart transplantation rejection. Methods Model of mice cervical heterotopic heart transplantation was set up, 96 mice were divided into three groups with random number table, control group： heart transplantation between C57 mice; transplant group： heart from BALB/C mice transplant to C57 mice; IL-10 group： IL-10 was transfected on BALB/C mice isolated heart for 1 hour, then transplanted to C57 mice. The messenger ribonucleic acid （mRNA） level expression of CD44 ,selectin-E ,LFA-1 ,VCAM-1 and IL-10 were measured by reverse transcription-polymerase chain reaction （RT-PCR） at the 5th day after transplantation. Results The mRNA level expression of CD44, selectin-E ,LFA-1 ,VCAM-1 in transplant group were significantly increased than those in control group （P〈0.01）. The mRNA level expression of CD44, selectin-E, LFA-1 ,VCAM-1 in IL-10 group were significantly decreased than those in transplant group （P〈0.01）. Conclusion IL-10 gene transfer is able to decrease the expression of CD44, selectin-E,LFA-1 ,VCAM-1 and suppress the heart transplantation rejection in mice.
Objective To investigate the optimal surgical approach for bilateral inguinal hernias and complex (recurrent and compound) inguinal hernia. Methods Data of eighty patients with bilateral inguinal hernias and (or) complex inguinal hernias treated by tension less hernia repair between Feb. 2007 and Jun. 2010 in Sichuan Provincial People’s Hospital were analyzed. Preperitoneal approach through inferior abdominal median incision was applied in the repair with local, lumbar or epidural anesthesia. Results Operation time was （30±10.2） min in unilateral hernia, （50±17.5） min in bilateral hernia. There was no ischemic orchitis or pain case after operation. Within 3 months following up, no recurrence occurred. Conclusion The preperitoneal approach through inferior abdominal median incision for inguinal hernia repair is proved to be effective, safe, and convenient, and especially fit for bilateral hernias and complex hernia.
目的 通过非小细胞肺癌（NSCLC）图像引导放射治疗（IGRT）过程中，每次治疗前获取的锥形束CT图像，动态观察肿瘤体积的变化。 方法 2009年2月－2010年8月18例周围型NSCLC患者接受IGRT。每次治疗前进行千伏级锥形束CT（KV-CBCT）图像的采集。每周在KV-CBCT图像上勾画肿瘤靶区并计算靶区体积，经统计后分析肿瘤治疗过程中体积的变化。 结果 治疗开始时平均体积为28.5 cm3（2.5～109.1 cm3），治疗结束时平均体积为17.1 cm3 （1.4～73.4 cm3）。平均退缩率为35.9%（3.9%～68.9%），平均每天的退缩率为1.5% （0.1%～5.4%）。治疗结束时，0例病灶完全消退，1例部分消退，10例微小消退，7例稳定。 结论 治疗过程中，NSCLC肿瘤的退缩可以通过KV-CBCT进行观察。当病灶为周围型时，能对肿瘤体积的变化进行客观有效的评价。放射治疗过程中肿瘤的体积改变具有很大的异质性，肿瘤在治疗过程中体积均有一定的退缩，但治疗结束时大多数病灶仅为微小消退或稳定。
