OBJECTIVETo explore the surgical methods and advantages of single rib-cartilage recombination transplantation in Binder syndrome treatment.
METHODSFive patients were treated with single rib-cartilage recombination transplantation. We harvested only the seventh costal cartilage including partial costal bone of the same rib to correct all the deformities. The rib was divided into 3 parts: 1 I-shaped cartilage, 1 inverted-T-shaped cartilage, and 1 C-shaped implant (later divided into a C and a reversed-C implant) composed of rib bone and cartilage. The first 2 parts were constructed to an L-shaped implant for nasal dorsum augmentation, collumella support, and nasal base elevation. The C-shaped and reversed-C-shaped implants were placed on both sides of the pyriform aperture.
RESULTSAll patients were followed up for eighteen to thirty months. No apparent deviation on the nasal support was found.
CONCLUSIONSingle rib-cartilage recombination transplantation in Binder syndrome treatment has lots of advantages, such as less morbidity, rapid recovery, and good results.

Objective To evaluate the prognostic significance of 3 clinical stage system in 3-dimensional conformal radiotherapy (3DCRT) for esophageal squamous cell carcinoma. Methods From January 2004 to August 2007, 179 cases of esophageal squamous cell carcinoma were treated with 3DCRT.Before radiation, each patient was staged with UICC 2003 TNM stage, stage of Chinese esophageal cancer cooperation group (cooperation group' stage), and Zhu's clinical stage respectively. Concordance of each clinical stage and prognosis was analyzed with SPSS 11.5. Results In 179 cases of esophageal cancer,Concordance was better in T stage ( Kappa = 0. 271 ) than in TNM stage ( Kappa = 0. 167 ) between cooperation group' stage and Zhu's stage. Among them, 98 cases was staged with UICC stage, concordance of T stage was better between UICC-T and cooperation group' T stage (Kappa =0. 261 ) than between UICCT and Zhu's T stage (Kappa = 0. 045 ) ;concordance of TNM stage was better between UICC-TNM and Zhu's TNM stage ( Kappa = 0. 597 ) than between UICC-TNM and cooperation group' TNM stage ( Kappa =0. 299 ). With multivariate analysis, T ( χ2 value is 11.58, 26. 00 and 51.05, all P < 0. 01 ), N ( χ2 value is 15.28, 16. 10 and 16. 10,all P<0. 01), M (χ2 value is 5.59, 27.78 and 27.78,all P<0. 01), and TNM (χ2 value is 15.77, 34,35 and 51. 10,all P<0. 01 ) stage in 3 kinds of clinical stage were independent prognostic factors. In UICC stage, T1-T3 was difficult to definite and the prognosis was not significantly different in T1 -T3 stage.

Objective To apply RNA interference technique for reducing the expression of MDC1 gene in esophageal carcinoma cell line ECA109, observe the changes in cell cycle and radiosensitivity after radiation, and discuss related mechanisms. Methods Three pairs of effective interference sequences and negative control sequences were synthesized for MDC1 mRNA sequence, and a recombinant plasmid was constructed with the vector pSIH1?H1?copGFP. RT?PCR and Western blot were used to determine the expression levels of MDC1 mRNA and protein. Colony?forming assay was applied to measure radiosensitivity, flow cytometry to determine cell cycle, Western blot to determine the expression of CHK1 and CHK2 proteins, and laser scanning confocal microscope to observe the number of MDC1 blotches inside the nucleus. One?way analysis of variance was used to analyze the differences between groups. Results The pSIH1?H1?copGFP plasmid was constructed successfully and ECA109 cells were infected to obtain ECA109M cells with stable transfection. The expression levels of MDC1 mRNA and protein in ECA109M cells were lower than those in ECA109N and ECA109 cells ( P= 0. 032 and 0. 041, respectively ) . After 5?Gy radiation, ECA109M cells had a lower proportion of G2+M cells than ECA109N and ECA109 cells ( P=0. 026) . After 5?Gy radiation, ECA109, ECA109N, and ECA109M cells had similar expression levels of CHK1 and CHK2 proteins ( P= 0. 345 and 0. 451, respectively ) , and ECA109M cells had a lower expression level of CHK2 T68 protein than ECA109 and ECA109N cells ( P=0. 012) . ECA109 cells had a D0 value of 3. 06 Gy and an SF2 value of 0. 91;the D0 values for ECA109N and ECA109M cells were 2. 90 Gy and 1. 88 Gy, respectively, and the SF2 values for them were 0. 89 and 0. 84, respectively ( P=0. 021 and 0. 037, respectively ) . Conclusions RNA interference can reduce the expression levels of MDC1 protein and cell cycle?related proteins, release cell cycle arrest, and enhance radiosensitivity in esophageal carcinoma ECA109 cells.

Objective: To identify the relationship between the expression of protein tyrosine phosphatase non-receptor type 12 (PTPN12) and radiotherapy effect in non-small cell lung cancer (NSCLC) tissues and to determine whether PTPN12 deficiency can sensi-tize lung cancer cells to irradiation. Methods: From September 2013 to October 2014, 92 NSCLC patients undergoing radiotherapy with or without platinum-based combination chemotherapy were analyzed retrospectively. Before the treatment, PTPN12 expression was detected through immunohistochemistry. After the completion of radiotherapy, the patients' responses were assessed and radio-therapeutic efficacy analyzed. The human NSCLC cell line H1299 was infected with shPTPN12 knockdown, and colony survival assay was analyzed after irradiation. Chi-square test was used to examine the correlation between PTPN12 expression and clinicopathologi-cal characteristics. Univariate analyses and Logistic regression test were used to analyze the relationship between clinicopathological characteristics and radiotherapeutic response. Results: Patients with low PTPN12 expression were more sensitive to radiotherapy than those with high PTPN12 expression (80.0%vs. 57.1%, P=0.018). Multivariate analysis showed that PTPN12 expression was the on-ly independent predictor of radiotherapeutic response in NSCLC. The H1299-shPTPN12-knockdown cells were sensitive to irradiation. Conclusions:The results of the study indicated that downregulation of PTPN12 improved the radiosensitivity of NSCLC cells.
