RESUMEN
Objective To explore MRI features in diagnosis of placenta accrete(PA).Methods MRI images of 19 patients with PA and 14 normal subjects were reviewed retrospectively.MRI features of the placenta and adjacent structures were analyzed and compared.Results Compared to the MRI findings of the normal subjects,abnormal uterine bulging,heterogeneous signal intensity of the placenta,and hypo-intensity intraplacental bands on T2WI were significantly higher in the patients with placenta accrete (P= 0.000,P=0.003 and P=0.015,respectively).The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of the three features diagnosing placenta accrete were 78.95%,85.71%,88.24%,75.00%,81.82%;84.21%,71.43%,80.00%, 76.92%,78.79%;73.68%,71.43%,77.78%,66.67% and 72.73%,respectively.Conclusion MRI has important value in diagnosing PA.The MRI features of abnormal uterine bulging,heterogeneous signal intensity within the placenta,and hypo-intensity intraplacental bands on T2WI are useful for diagnosis.
RESUMEN
Objective To observe the clinical efficacy of herbs by internal and external administration combined with semiconductor laser irradiation in the treatment of chronic eczema.Methods Eighty-six patients with chronic eczema were divided into the herb group and the laser group by the randomized digital table,43 patients in each group.The patients in the herb group received oral administration with Chinese herbs together with application of herbs on the affected foci.The patients in the laser group received the same treatment as in the herb group and meanwhile treated with additional semiconductor laser therapy.The clinical effects were evaluated according to their itch degree and skin lesions.Result The cure rate and total effective rate were both significantly higher in the laser group than those in the herb group(P<0.05).Conclusion Compared with herbal internal and external administration only,the clinical efficacy of herbal internal and external administration combined with semiconductor laser irradiation is more effective in the treatment of chronic eczema.
