ABSTRACT
Objective To analyze the characteristics of left ventricular systolic function in Kawasaki disease (KD) patients with intravenous immunoglobulin (IVIG) resistant during acute phase by two-dimensional speckle tracking imaging (2D STI).Methods IVIG resistant patients (n=40) as well as age and gender matched IVIG responder patients (n=40) were selected from KD patients in acute phase.Patients in IVIG resistant group were further divided into coronary artery dilation (CAD) subgroup and no coronary artery dilation (NCAD) subgroup.Then conventional echocardiography,2D STI and laboratory indexes were acquired and compared between IVIG resistant group and IVIG responder group,as well as between CAD and NCAD subgroup.ROC curve analysis was used to determine threshold values of 2D STI measurements associated with IVIG resistance.Results Compared with IVIG responder group,coronary artery dilation,left ventricular mass and left ventricular mass index increased,systolic global longitudinal strain (GLS) and systolic global circumferential strain (GCS) decreased,albumin,erythrocyte sedimentation rate,C-reactive protein and platelet increased in IVIG resistant group (all P＜0.05).Taking absolute GLS 16.8％ as a threshold,the area under curve (AUC) was 0.769 (P=0.021),sensitivity,specificity in diagnosis of IVIG resistant was 79.27％,68.36％.Taking absolute GCS 15.9％ as a threshold,AUC was 0.749 (P=0.038),sensitivity,specificity in diagnosis of IVIG resistant was 71.43％,57.28％.Conclusion IVIG resistant KD patients present significantly greater systolic dysfunction compared with responders in patients with KD,which may be the results of myocardium infection other than coronary artery lesions.2D STI may predict myocardial injury in IVIG resistant KD patients.
ABSTRACT
Objective To systematically analyze and assess the overall value of transrectal shear wave elastograpy in diagnosis of prostate cancer (PCa) using Meta-analysis.Methods Relevant Chinese and foreign papers diagnosing PCa with transrectal shear wave elastograpy published before December 2016 were searched.The references were evaluated and screened according to the criteria of diagnostic research.The selected references were analyzed by Meta-Disc 1.4 and Stata 12.0 statistical software.Results Eight articles were included in the present Meta-analysis.Five of these literatures were about transrectal shear wave elastograpy in diagnosis of PCa,the summarized sensitivity (SEN) and summarized specificity (SPE) in diagnosis of PCa were 0.80 (95％CI [0.75,0.84]) and 0.75 (95％CI [0.71,0.79]),respectively;the positive likelihood ratios (PLR) and negative likelihood ratios (NLR) were 3.60 (95 ％ CI [2.57,5.05]) and 0.17 (95 ％ CI[0.08,0.37]),respectively;the area under SROC curves was 0.895.Five of these literatures were about transrectal shear wave elastograpy supplemental prostatic biopsy in diagnosis of PCa,the summarized SEN and SPE were 0.86 (95％ CI [0.83,0.88]) and 0.84 (95％CI [0.82,0.85]) respectively;the PLR and NLR were 5.81 (95％CI [3.07,10.99]) and 0.14 (95％CI [0.04,0.49]) respectively;the area under SROC curves were 0.924.Conclusion Transrectal shear wave elastograpy has better clinical value in detection of PCa and can be used to supplemental prostatic biopsy.
