Objective Early clinical symptoms of esophageal cancer are often not obvious , so a deeper insight into tumor markers is very important for the early diagnosis of esophageal cancer .This study was to investigate the expressions of Rock 2 and Wnt11 in the specific esophageal cancer cell lines Eca-109 and HEEC and the relationship of the signal transduction pathway of proteins with the development of esophageal cancer . Methods Esophageal cancer cell lines Eca-109 and HEEC were cultured and the expression levels of Rock2 and Wnt11 in the cell lines were determined by real-time quantitative PCR and Western blot . Results The mRNA expressions of Rock2 and Wnt11 were significantly increased in the Eca-109 as compared with those in the HEEC cell line (4.955± 0.539 vs 1.000±0.000, P<0.01;2.925±0.230 vs 1.000±0.000, P<0.01), and so were the protein expressions of Rock 2 and Wnt11 (955.000±21.628 vs 778.844±102.193, P<0.05;2175.316±145.623 vs 1312.233±50.734, P<0.05). Conclusion The up-regula-ted expressions of Rock 2 and Wint11 may be the markers of the metastasis of esophageal squamous cancer .

Objective:To determine the value of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) scans in identify-ing the residual retroperitoneal tumor after chemotherapy of testis germ cell tumors. Methods:Sixteen testis germ cell tumor patients with metastasis of retroperitoneal lymph nodes who were treated in our hospital from February 2014 to December 2016 were select-ed for the study from February 2014 to December 2016. After 4-6 cycles of chemotherapy, their CT scans showed residual masses with diameters greater than 2 cm. The retroperitoneal lymph nodes were dissected after the 18F-FDG PET exam. The post-surgery pathology results were compared with the results of the 18F-FDG PET exam. Results:Residual tumors were found in 5 of 10 patients with 18F-FDG PET positive. Residual tumor was absent in 4 of 6 patients with 18F-FDG PET negative, while residual mature teratoma tumors were found in two patients. The accuracy rate, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the 18F-FDG PET exam were 56.25%(9/16), 71.42%(5/7), 44.44%(4/9), 50.00%(5/10), and 66.67%(4/6), respectively. Conclusion: 18F-FDG PET is highly sensitive. However, many factors influence the result of 18F-FDG PET. Mature teratoma leads to a false negative re-sult, whereas massive tissue inflammation leads to a false positive result. Therefore, more clinical examinations should be made.

OBJECTIVETo explore the role of autophagy in quercetin (Que)-induced apoptosis in human bladder carcinoma BIU-87 cells in vitro.
METHODSTo determine the proliferative inhibition by MTT colorimetric assay after treating BIU-87 cells with quercetin at various concentrations. To identify autophagy and apoptosis in the BIU-87 cells after Que treatment by monodansylcadaverin (MDC) and Hoechst 33258 fluorescent staining, respectively. To examine the cytotoxic effect of Que and influence of autophagy on apoptosis by studying LDH leakage rate and flow cytometry, after blocking the autophagy with 3-methlyadenine (3-MA), a specific autophagy inhibitor.
RESULTSThere was an obvious inhibitory effect of Que on the proliferation of BIU-87 cells in a time- and dose-dependent manner. The inhibition rate of BIU-87 cells after 200 µmol/L Que treatment for 72 hours was 89.2%. Autophagy and apoptosis were induced and detected in Que-treated BIU-87 cells and autophagy occurred earlier than apoptosis. The apoptosis peak became much higher after the autophagy was blocked. Whenever the autophagy was blocked before or after Que treatment, the Que-induced cytotoxicity in BIU-87 cells was enhanced.
CONCLUSIONSQuercetin significantly inhibits the proliferation of BIU-87 cells, and the autophagy is induced earlier than apoptosis. In the process of Que-induced apoptosis of BIU-87 cells, autophagy may play a protective role at the initiation phase, delay apoptosis and reduce the Que-induced death of BIU-87 cells.
