Seventy-one ASC patients were retrospectively evaluated. FC level within 3 days of colonoscopy was measured with ELISA. Demographic and clinical data, laboratory parameters, and medical therapy were documented, and the endoscopic severity of disease was rated by UCEIS. The end points were the rate of failed corticosteroid therapy, colectomy, and mortality. There was significant correlation between UCEIS and FC level (r=0.729, P1672 µg/g, sensitivity and specificity were 80.2 and 66.7%, respectively, in prediction for colectomy using receiver operating characteristics analysis. The results indicated that FC, as a non-invasive indicator, correlates positively with the UCEIS. Baseline FC level predicts clinical outcomes in ASC patients, which make a timely treatment strategy conversion possible after accurately forecasting the likelihood of failure of intravenous steroid therapy.A number of previous studies have demonstrated that inhibiting autophagy can increase the cellular cytotoxicity of chemotherapeutic agents in urothelial cancer cells. However, the mechanistic roles of autophagy in gemcitabine (GEM) resistant bladder cancer cells have not been thoroughly investigated. In the present study, immunohistochemistry staining of autophagy marker LC3 was performed in bladder cancer and healthy control tissues and demonstrated an essential role of autophagy in cancer development. A GEM-resistant cell line was established to assess the effects of autophagy on the acquisition of GEM resistance. Western blotting of autophagy markers in GEM-resistant bladder cancer cells suggested that GEM resistance was caused, at least partially, by GEM-induced autophagy. GEM resistance was demon
