0.05);the persons with hypersexuality from 25 to 31 age had the highest infection percentage and it taken 75% of all the NGU.The minocycline and doxycycline were sensitive and ciprofloxacin was a resistant drug.CONCLUSIONS In our hospital,the Uu is still a main pathogen,and the minocycline and doxycycline are the fist choice to treat it.At the same time,the NGU survey and the antibacterial susceptibility tests are very important.

Objective To explore the diagnostic value of full-field digital mammography (FFDM) combined with digital breast tomosynthesis (DBT) in breast diseases.Methods 506 patients receiving mammary gland molybdenum target inspection from January 1, 2014 to December 31, 2014 were selected.The images from FFDM and DBT were analyzed, respectively.The breast imaging reports and pathological results were compared to investigate the sensitivity, specificity and accuracy of FFDM, DBT alone and combined use of DBT and FFDM.Results The results of preoperative mammography in the 506 women (bilateral breast) were as follows: FFDM combined with DBT detected 202 benign cases (39.9%) and 304 malignant cases (60.1%);FFDM alone detected 194 benign cases (38.3%) and 312 malignant cases (61.7%);DBT alone detected 187 benign cases (37.0%) and 319 malignant cases (63.0%).Pathologically, 214 benign cases (42.3%) were detected and 292 malignant cases (57.7%).In terms of the sensitivity, specificity and accuracy, The combined use of DBT combined with FFDM was the best, followed by FFDM alone and DBT alone.Conclusion The sensitivity, specificity and accuracy of FFDM combined with DBT for diagnosis are better than those of FFDM alone or DBT alone.

Background and purpose:Anticancer mechanism of epigallocatechin-3-gallate(EGCG)remains unclear.This study investigated the role of reactive oxygen species(ROS)in epigallocatechin-3-gallate(EGCG)-induced apoptosis in human gastric cancer MGC803 cells.Methods:The inhibition of MGC803 cells growth was measured by MTT assay.Apoptosis of MGC803 cells was studied by using the AO/EB fluorescence stain.Flow cytometry was used to detect the intracellular ROS level and the rate of apoptosis.Results:EGCG could induce apoptosis of MGC803 cells and increased in the intracellular ROS level.However,after treatment with N-acetyl-L-cystein and an athiol-containing antioxidant,the inhibitory effect of EGCG on MGC803 cells was significantly weakened.The apoptotic rate of the cells and the activity of the intracellular ROS level also decreased dramatically.Conclusion:EGCG can induce apoptosis of MGC803 cells.In turn,the ROS inhibitor can significantly inhibit the apoptosis induced by EGCG in MGC803 cells.These results suggest that the cellular generation of ROS plays a role in initiating EGCG-mediated apoptosis of MGC803 cells.
