To study the etiology and treatment of relapsing polychondritis, especially tracheostenosis, 3 patients with severe relapsing polychondritis complicated with severe tracheostenosis were presented. The clinical features, criteria of diagnosis, etiology, therapy and prognosis were discussed. All the 3 cases were female. They were misdiagnosed as laryngopharyngeal inflammation with severe tracheostenosis, so that their correct diagnosis and treatment were delayed. The report and discussion of such cases are helpful to its early diagnosis and improve ment of their prognosis.

Objective To analyze the risk factors of refractory postoperative stenosis after large-scale endoscopic submucosal dissection (ESD) for patients with early esophageal cancer.Methods The data of 35 postoperative stenosis patients previously treated by ESD (dissection ≥3/4 circumferential) for early esophageal cancer from January 2011 to September 2016 in Digestive Endoscopy Center, Changhai Hospital were reviewed.According to the number of endoscopic dilation, 35 patients were divided into two groups: refractory stenosis (≥6 endoscopic dilations, n=21) and non-refractory stenosis (≤5 endoscopic dilations, n=14), comparison between the two groups was performed using t test or Fisher exact probability method.Results Muscle layer damage (P=0.018), longitudinal mucosal defect length (P=0.013), tumor infiltrating depth (P=0.031), and the number of hemostatic clips (P=0.031) were significantly different between the two groups.The history of chemotherapy and radiotherapy, the location of tumor, the macroscopic type, and the postoperative administration of oral prednisolone were not significant differences between the two groups (P>0.05).Conclusion Refractory esophageal stenosis commonly occurs in patients undergoing large-scale ESD with tumor depth >M2, muscle layer damage, longitudinal mucosal defect length ≥50 mm and the number of hemostatic clips ≥6.

Objective To explore the effects of inducible co-stimulator (ICOS) gene on the cytotoxic activity of cytokine-induced killer (CIK) cells against cholangiocarcinoma cells. Methods CIK-ICOS cells were obtained by stable transfecting ICOS genes into CIK cells through the adenovirus vector whereas untransfected and EGFP-transfected CIK cells were treated as controls. The proliferation and apoptosis of different CIK cells, as well as their cytotoxicity against cholangiocarcinoma cells in the three groups were detected. The expressions of IFN-T, IL-2 and TNF-α in the supernatant of different CIK cells were measured by ELISA. SCID mice with cholangiocarcinoma were randomly divided into CIK group, CIK-EGFP group, CIK-ICOS group and normal saline group. The cytotoxic activity of CIK-ICOS cells against cholangiocarcinoma cells in vivo was observed. Results CIK-ICOS cells displayed better proliferation than CIK cells and CIK-EGFP cells. At day 20 and 23 of culture, the apoptosis rate of CIK-ICOS cells was 0.69% and 0.89%, respectively, while that of the CIK cells was 2.90% and 4.92%. The cytotoxic effect of CIK-ICOS cells at different E: T ratio against cholangiocarcinoma cells was significantly stronger than that of CIK cells and CIK-EGFP cells (F=13.37, 6.46, 25.51, P<0.05). The concentration of IFN-γ in CIK-ICOS cultured supernatant was (49.50±4.73)μg/L, which was significantly higher than that in the cultured supernatant of CIK cells [(30.53±3.73)μg/L] and CIK-EGFP cells [(30.12±2.64)μg/L](F=38.89, P<0.05). The growth of cholangiocarcinoma was significantly slower in CIK-ICOS group than that in CIK group and CIK-EGFP group, whereas the necrosis area of tumor was larger and the CIK cells in CIK-ICOS group was more than those in the other two groups. Conclusions CIK cells had the function of killing cholangiocarcinoma cells in vitro and in vivo. After ICOS genes were transfected into CIK cells, the survival time of CIK cells in vitro was prolonged and the proliferation of CIK cells was enhanced, as well as the secretion of IFN-γ was increased so that the cytotoxicity of CIK cells against cholangiocarcinoma cells in vitro and in vivo was enhanced.

Objective To investigate the value of functional MRI in the diagnosis and differential diagnosis of breast diseases.Methods Sixty-five patients with 68 lesions were enrolled in this study. Conventional T_1 WI and T_2 WI scan,dynamic contrast enhanced MRI,diffusion weighted imaging and ~1H single voxel MR spectroscopy were performed consequently.All lesions were verified by pathology,including 4 cases of breast adenosis,22 fibroadenomas,2 chronic inflammations,3 cysts,33 infitrating ductal carcinomas,1 intraductal carcinoma and 3 cystosarcoma phyllodes tumors.Morphological features,maximum enhancement ratio,time-intensity curve,apparent diffusion coefficient and Choline peak were analyzed. Results The detection rates of T_1 WI and T_2 WI were 14.7%(n=10)and 51.5%(n=35).The sensitivity,specificity,accuracy of dynamic contrast.enhanced MRI for the malignant tumor were 94.6%, 71.4% and 76.5% respectively.Retrospective study showed that diffusion weighted imaging,with the b value from 800 s/mm~2 to 1000 s/mm~2,could be used to differentiate various types of breast lesions.~1H signal voxel spectroscopy had a sensitivity of 51.4%,specificity of 82.6%,and accuracy of 67.6% for the malignent.The sensitivity,specificity and accuracy could reach 97.3%,90.0% and 92.6% respectively by combining conventional scan,dynamic contrast enhanced MRI and MR spectroscopy.Conclusion Functional MRI,with high sensitivity,specificity and accuracy,can be used widely in the diagnosis of malignant breast lesions.

Aim To investigate the anti-tumor effects of FS-108 an Hsp90 inhibitor, on oncogene addicted EBC-1 and A375 cells. Methods SRB assay was performed to investigate cell proliferation. Immunoblot was conducted to investigate the specific proteins. FACS was conducted to test cell cycle distribution and apoptosis. Transwell assay was conducted to investigate cell motility. Results FS-108 significantly suppressed cell proliferation of EBC-1 and A375 cancer cells with IC50 at 25. 53 nmol · L-1 and 30. 02 nmol · L-1 re-spectively. FS-108 treatment triggered the degradation of key client proteins such as c-Met and B-Raf and thereby reduced their downstream AKT and ERK signa-ling pathways. The FACS analysis results demonstrated that FS-108 treatment induced G2/M phase arrest and apoptosis significantly. Furthermore, FS-108 inhibited the migration of EBC-1 and A375 cells. Conclusion As a potent Hsp90 inhibitor, FS-108 can inhibit onco-gene addicted cancer cells proliferation through induc-tion of G2/M phase arrest and apoptosis.

Myopia is one of the most popular eye diseases all over the world. The development of the current understanding of its mechanism is still limited. Many studies indicated that the growth factors closely related to eye development and myopia. Some growth factors with biological activity, such as transforming growth factor ( TGF ), fibroblast growth factor ( FGF ) and epidermal growth factor ( EGF ), have an impact on scleral thickness variation, the regulation of the development of myopia and so on, which plays a non-negligible role in the pathogenesis of myopia. In this paper, the function of various growth factors in myopia will be reviewed.
