Objective To assess the value of SureTouch tactile breast imaging (SureTouch) in early breast disease detection.Methods From April 2009 to March 2011,16 010 adults received health checkup in our center,5000 of whom took breast screening and were randonly selected to accept SureTouch.The results of the SureTouch were reviewed.Results In SureTouch,799 participants were normal,resulting in an abnormal rate of 84.02％.Four thousands and nineteen adults were found with breast hyperplasias (80.38％) and 150 with breast nodulars (3.00％),and another 32 women were suspected with malignant condition (0.64％).Breast hyperplasia was the most commonly seen disease in all age groups,although breast nodular and malignant changes were mainly found in 35-50 age group.The incidence of malignant disease showed a trend of affecting younger females.Pathological follow-up results of two controversial cases supported the diagnosis of SureTouch.Conclusions SureTouch shows high sensitivity in this study.The application of SureTouch in breast screening may play an important role in the early detection,diagnosis and treatment of breast diseases.

Objective To investigate the association between inflammatory biomarkers and survival in patients with stable chronic obstructive pulmonary disease(COPD).Methods A total of 1038 patients with stable COPD from January 2008 to December 2009 were included in a prospective cohort study.Clinical characteristics,pulmonary function tests,6 min walk test and a modified British Medical Research Council dyspnea scale (MMRC) were completed.Fasting blood was obtained to detect inflammatory biomarkers including neutrophils,C-reactive protein(CRP),fibrinogen,TNF-a,IL-6 and IL-8.Participants were evaluated every 3 months,all-cause mortality was used as the end event.Results 120 patients (9.2％) died in the period of follow-up.Kaplan-Meier analysis showed that 1 year,2-year-and 3-year survival rates were 94.4％,88.3％ and 84.0％,respectively.Compared with survivors,those who died had a higher level of inflammatory biomarkers.Cox multivariate regression analysis demonstrated that the independent risk factors for death were neutrophils (HR:1.262,95％CI:1.143-1.512,P=0.035),CRP (HR:1.234,95％CI:1.097-1.624,P=0.029),fibrinogen (HR:1.327,95％CI:1.141-1.619,P=0.026),TNF-α (HR:1.124,95％CI:1.043-1.659,P=0.045),IL-6 (HR:1,429,95％CI:1.237-1.816,P=0.014) and IL-8 (HR:1.188,95％CI:1.024-1.383,P=0.042).C statistical analysis showed that no single biomarker significantly improved the C statistic value on the base of clinical model,but it was further improved by the addition of all biomarkers (C =0.764,P =0.010).Conclusions The level of inflammatory biomarkers in the death with stable COPD is significantly increased.Age.BODE index,neutrophils,CRP,fibrinogen,TNF-α,IL-6 and IL-8 are independent risk factor for the prediction of mortality in patients with COPD.

Two hundred and thirty-five patients of both sexes (123 male,112 female) aged 18-54 yr,weighing 35-62 kg underwent repair of tetralogy of Fallot from January 1996 to July 2009 in Fuwai hospital.Direct BP, ECG,CVP,SpO2,naso-pharyngeal temperature and TEE were continuously monitored during operation.Anesthesia was induced with midazolam and/or etomidate, fentanyl and pipecuronium and maintained with isoflurane/sevoflurane inhalation and intermittent iv boluses of fentanyl and pipecuronium. The total amount of fentanyl administered ranged from 30-50 μg/kg. Cardiac function was supported and hemodynamic stability was maintained with vasoactive and inotropic drugs. Measures were taken to strengthen blood conservation and respiratory function support.Seven patients(2.9%) needed urgent CPB during operation because of serious cyanotic spells. Perfusion-induced lung injury occurred in 18 patients (7.6%). Circulation was assisted by ECMO in 2 patients (0.9%). Three patients (1.3%) died of serious low cardiac output and perfusion-induced lung injury.
