Mortality and potential life lost of drowning in Zhoushan residents / 预防医学

Objective@#To learn the characteristics of drowning deaths and potential years of life lost（PYLL）among residents in Zhoushan，and to provide basis for formulating drowning prevention and control measures. @*Methods@#The death surveillance data in Zhoushan from 2009 to 2018 were collected from Zhejiang Chronic Disease Surveillance Information Management System. Demographic features，causes of drowning，life and labor lost due to drowning were analyzed through indicators such as mortality，standardized mortality，early death index，PYLL and working potential years of life lost（WPYLL）. @*Results@#The crude and standardized drowning mortality of Zhoushan residents were 7.97/100 000 and 4.68/100 000. The drowning mortality showed a decreasing trend from 2009 to 2018（P<0.05）. The mortality of drowning in males was 8.03/100 000，which was higher than 1.33/100 000 in females（P<0.05）. Totally 322 deaths from drowning were fishery workers，accounting for 41.44%. The main cause of drowning death in residents aged 0-14 years，15-29 years and 65 years or above was accidental fall，accounting for 36.11%（13 cases），23.91%（11 cases）and 14.40%（47 cases），respectively. The main cause of drowning death in residents aged 30-44 years and 45-64 years was ship accident，accounting for 33.33%（58 cases）and 36.01%（130 cases），respectively. PYLL and WPYLL caused by drowning death were 22 511 and 11 911 person-years，of which residents aged 30 to 64 years were accounted for 73.33% and 70.55%. The early death index was 28.97. @*Conclusion@#Drowning mortality in Zhoushan showed an downward trend from 2009 to 2018. Men and fishery workers are at higher risk of death from drowning. Drowning can lead to serious life loss，especially for population aged 30-64 years.

Value of endobronchial ultrasound-guided localization with combination of ultrathin bronchoscope and methylene blue for small pulmonary nodules before video-assisted thoracoscopic surgery / 中华胸心血管外科杂志

Objective To analyze the value of endobronchial ultrasound-guided ultrathin bronchoscope(EUGUB) and methylene blue positioning video-assisted thoracoscopic surgery(VATS) for small pulmonary nodules.Methods Sixty patients undergoing VATS, using pre-operative EUGUB combination with methylene blue was performed .The positioning accuracy, the complications and pathological classification were analyzed .Results EUGUB combination with methylene blue positioning ac-curacy was 91.7%, meanwhile, 2 patients with hemoptysis with no conservative treatment.The postoperative histological pa-thology results showed that benign lesions and malignant lesions accounted for 28.3% and 71.7%, respectively.Conclusion The method of EUGUB combination with methylene blue in positioning of the small pulmonary nodules increases the achieve-ment ratio of VATS with few complications, and may be widely used in treatment of small pulmonary nodules with VATS.

Correlation between atlE gene and biofilm formation of Staphylococcus epidermidis / 国际检验医学杂志

Objective To investigate the correlation between atlE gene and biofilm formation of Staphylococcus epidermidis . Methods 64 strains of clinically isolated Staphylococcus epidermidis in our hospital from June 2015 to June 2016 were collected . The biofilm formation test was used to detect bacterial biofilm .PCR was use to amplify atlE gene .Then the correlation between the atlE gene with biofilm formation was analyzed .Results 24 strains of biofilm positive bacterium were detected ,the detection rate was 37 .5% ;31 strains of atlE gene was detected ,the detection rate was 48 .4% ;atlE gene was significantly correlated to biofilm formation(P＜0 .05) .Conclusion Staphylococcus epidermidis has the ability to form biofilm ;atlE gene has a relation with biofilm formation of Staphylococcus epidermidis .
