ABSTRACT
【Objective】 To investigate the risk factors and predictive effectiveness of prostate imaging reporting and data system (PI-RADS) score for patients with clinically significant prostate cancer (CsPCa) whose PI-RADS score was 3, so as to provide evidence for the diagnosis and treatment. 【Methods】 The clinical and multi-parameter magnetic resonance imaging (mpMRI) data of 153 CsPCa patients treated during Jan.2017 and Dec.2021 whose PI-RADS score was 3 were retrospectively analyzed. With PI-RADS score of 3 as the independent risk factor for CsPCa, the other relevant independent risk factors in predicting CsPCa were evaluated. 【Results】 Univariate and multivariate analyses showed that prostate-specific antigen (PSA) density and apparent dispersion coefficient (ADC) were independent risk factors for the diagnosis of CsPCa (P<0.05). Analysis of receiver operating characteristic (ROC) curve showed that combined PSA density and ADC were more effective than PSA density and ADC alone (P<0.05). 【Conclusion】 The combination of PSA density and ADC can guide clinicians to identify high-risk CsPCa patients from patients with PI-RADS score of 3 points.
ABSTRACT
Objective@#To evaluate the sensitivity and specificity of exhaled nitric oxide in the diagnosis and therapy of bronchial asthma.@*Methods@#From January 2016 to December 2017, 87 patients diagnosed with bronchial asthma in Luoyang Central Hospital Affiliated to Zhengzhou University were selected as asthma group , and 40 healthy people were selected as healthy control group at the same term.The levels of FeNO, FEV1/pred, peripheral blood EOS count, ACT score, percentage of sputum EOS were measured.@*Results@#The positive rate of FeNO was 56.3%(49/87) in the asthma group, which in the healthy control group was 5.0%(2/47). The fractional exhaled nitric oxide level of reexamined patients before treatment [(70.9±53.6)ppb] was higher than that after treatment[(12.2±8.7)ppb], and the difference was statistically significant(t=4.323, P=0.001). The fractional exhaled nitric oxide level in the asthma group [(42.4±42.5)ppb] was higher than that in the healthy control group [(9.4±5.8)ppb], and the difference between the two groups was statistically significant(t=2.871, P=0.001). The fractional exhaled nitric oxide level was positively correlated with peripheral blood EOS count (r=0.376, P=0.000) and ACT score (r=0.361, P=0.001), but had no correlation with FEV1/pred (r=-0.111, P=0.306) and sputum EOS (r=-0.036, P=0.805).@*Conclusion@#The measurement of fractional exhaled nitric oxide levels has an important clinical significance in the diagnosis of bronchial asthma.And it has a guiding significance for the evaluation of the therapeutic effect of bronchial asthma.
