Objective To study the effect and toxicity ofgefitinib combined with selected radiotherapy in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). Methods From March 2006 to February 2009,10 of 13 advanced NSCLC patients who got benefit from gefitinib were enrolled to treatment group (gefitinib concurrent selected radiotherapy) and control group (gefitinib only), with 5 cases in each group. The response was evaluated as progression free survival (PFS) and overall survival (OS).Results No patient got complete remission (CR). Ten of 13 patients got partial remission (PR) and stable disease (SD). The 1 year and 2 years survival rate was 53.8%(7/13) and 46.2%(6/13) respectively. The median PFS in treatment group and control group was 24 months and 8 months respectively(P= 0.0019). The median OS was 32 months and 10 months respectively (P= 0.0062). The main toxicities were reversible skin rash and diarrhea,and 3 patients developed asymptomatic radiation pulmonary fibrosis. Conclusions Gefitinib combining with selected radiotherapy is effective and tolerated in patients with advanced NSCLC. It may prolong PFS and OS. It may be a rational choice for the standard and individualized treatment of NSCLC.

Background To understand the distribution and development of corneal nerve in animal or human has an important significance for clinical and basic research of corneal diseases.At present,some studies on cornea nerve development and location have been performed.However,the quantified study on innervation and distribution of corneal nerve fibers as embryonic development has not been reported.Objective This study attempted to understand the distribution of corneal nerve fibers in the development of chick embryo,and to evaluate the changes of the length and density of corneal nerve fibers with aging of chick embryo.Methods Whole chick corneas with limbus were obtained from chick embryo aged 6-20 days (E6-E20),and corneal nerve fiber was labeled using immunofluorescence technique by anti-neuron-specific β-Ⅲ tubulin antibody.The corneas were radially cut into 4 parts,and the integrate corneal flat mounts were prepared with the upward epithelium and mounting with anti-fade fluorescent quenching buffer glycerin containing DAPI.Fluorescence microscope was used to capture the nerve fiber images in cornea,and cornea area and the number of nerve fiber bundles were exhibited by using Photoshop CS4.Cornea nerve fiber density and total length were measured by Imaris x64 7.4.2 software.Results Total cornea flat mounts showed that the nerve bundles grew from temporal scleral forward cornea limbus at E6-E8,and the nerve fibers formed the ring surrounding by limbus during E9-E10.Then the fibers extended forward the central cornea in E11 to E15 and developed into nerve fiber plexus on the whole cornea in E16 to E20.During the period of E6-E20,the corneal surface area,the length and density of corneal nerve fibers were gradually increased with the aging of chick embryo,showing statistically significant differences among different time points (F =127.007,227.051,67.748,all at P＜0.01).The increase of the corneal area of the chick embryo presented a strong positive correlation with the extending of length of the corneal nerve fiber (r =0.863,P＜0.01).Chick corneal nerve fiber bundle appeared at E13,with a number of (59.00 ± 1.14)/mm2 and then increased to a peak of (576.75 ±29.16)/mm2 at E 18 and reduced to (299.67± 25.46)/mm2 at E20,with a significant difference among them (F =13.759,P=0.000).Conclusions Corneal nerve starts to develop in E9 of chick embryo,and the corneal surface area,the total length of the corneal nerve fibers and the density rapidly increase concurrently with the development of chick embryo.

Objective To analyze the incidence and clinical features of urothelial tumors in renal allograft recipients.Methods A retrospective analysis of 1042 patients received renal allografts who had taken immunosuppression for at least six months between 2006 and 2011 in The First Centre Hospital of Tianjin was performed.Results Eleven cases of uroepithelial tumors were diagnosed in the 1042 cases of renal transplantation ( 1.06％ ),of whom 9 cases were noticed by hematuria ( 81.8 ％ ),2 cases ( 18.2％ ) by medical examination.Six patients were diagnosed with multifocal urothelial carcinomas.Surgery was performed on all the patients with renal tumors and followed by chemotherapy or radiotherapy.Conclusion Malignancies in urinary tract after renal transplantation should be bore in mind.Early diagnosis is very important.The treatment options include reducing immunosuppressive agents and removing tumor lesions completely.

Objective To evaluate the safety,feasibility and results of the hand-assisted retroperitoneal laparoscopic living donor nephrectomy ( HRPLDN ) with a modified technique. Methods Living donors (n =32) were divided into HRPLDN group (n =16) and open group (n =16) according to surgical technique.Operative data and postoperative outcomes including operative time,estimated blood loss,warm ischemia time,length of hospital stay and complication rate,were collected. Results All procedures were completed successfully.In HRPLDN group,the mean operative time was 101.3 ± 21.2 min (range from 70 to 150 min),with an estimated blood loss of 53.8 ±25.5 ml (range from 20 to 100 ml) and warm ischemia time of 2.4 ± 0.6 min ( range from 1.5 to 3.5 min).No living donor needed conversion to open surgery and the urine volume of transplanted kidney after first 24 hours was 5036 ml (range from 3500 -6500 ml).The mean postoperative on bed time were (2.8 ± 0.7 ) d (ranging from 2 -4 d).All parameters of HRPLDN were significantly better than that of open groups. Conclusion Living donor nephrectomy with HRPLDN is a safe and reliable surgical technique.
