The reporting rates of smoking status, smoking history and the number of cigarettes smoked daily were 95.5%, 98.6% and 98.6%, respectively. Compared to never smokers, the RR of ever smoking in males was 1.38 (95% CI 1.33-1.43) for all causes of smoking-related deaths and 3.07 (95% CI 2.91-3.24) for lung cancer, while in females the values were 1.46 (95% CI 1.39-1.54) for all causes of smoking-related deaths and 4.07 (95% CI 3.81-4.35) for lung cancer. The results in Tianjin are in accord with published results from previous studies. CONCLUSIONS Levels and trends in smoking attributed mortality can be measured at low cost by using the stable, complete and effective ACDS system in Tianjin. © 2020 Li W. et al.Background Sialolithiasis or salivary gland stones are associated with high clinical morbidity. The advances in the treatment of sialolithiasis has been limited, however, by our understanding of their composition. More specifically, there is little information regarding the formation and composition of the protein matrix, the role of mineralogical deposition, or the contributions of cell epithelium and secretions from the salivary glands. A better understanding of these stone characteristics could pave the way for future non-invasive treatment strategies. Methods Twenty-nine high-quality ductal stone samples were analyzed. The preparation included successive washings to avoid contamination from saliva and blood. The sialoliths were macerated in liquid nitrogen and the maceration was subjected to a sequential, four-step, protein extraction. The four fractions were pooled together, and a standardized aliquot was subjected to tandem liquid chromatography mass spectrometry (LCMS). The data output was subjected tohich suggests the possibility of a common origin. Further verification of a common origin could funda
