ABSTRACT
Objective To evaluate the diagnostic value of contrast-enhanced ultrasound in breast precancerous lesions . Methods Retrospectively analyzed the contrast-enhanced ultrasound model and angiographic predictive model of 465 cases of the A prospective multicenter study of breast nodules contrast-enhanced ultrasound" that led the Sichuan Provincial People′s Hospital from January 2016 to April 2017 ,which included 69 cases of breast precancerous lesions and 396 other types benign lesions ,and the sensitivity ,specificity and accuracy of the diagnosis of breast precancerous lesions were calculated . Results The sensitivity of ultrasound predictive model for the diagnosis of precancerous lesions was 60 .9％ and AUC was 0 .681 . Precancerous lesions mainly showed non-concentricity , increased homogeneity , and increased lesions;other types of benign lesions mainly showed non-centripetal ,high uniformity enhancement and lesion size unchanged . Conclusions Contrast-enhanced ultrasound shows a potential value in the differential diagnosis of precancerous lesions and other types of benign lesions ,that can help clinicians to take early intervention measures for breast precancerous lesions ,but there are still many problems to be solved .
ABSTRACT
Objective To evaluate the application value of time-intensity curve analysis of contrastenhanced ultrasonography (CEUS) in differential diagnosis of malignant and benign breast masses.Methods From January 2015 to September 2015,30 patients with one lesion confirmed by surgical pathology were examined by CEUS.Then time-intensity curve analysis was performed.Results 16 lesions were found in the benign group and 14 lesions were in the malignant group.Five parameters of benign and malignant group were statistically analyzed,including Perfusion slope rate (C),intensity of peak (A),Subsidence slope rate (K),time of peak value (T) and area under the curve (Area).The perfusion slope rate (C) of benign and malignant group is [(0.24 ± 0.41) vs (0.67 ± 0.39)].There was no statistical difference between the two groups in intensity of peak (A),Subsidence slope rate (K),time of peak value (T) and area under the curve (Area),except perfusion slope rate (P＜0.05).Conclusion Time-intensity curve analysis of CEUS has certain effect on differential diagnosis of malignant and benign breast masses.
ABSTRACT
ObjectiveTo investigate the clinical effect of EaLeSu on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with loop electrosurgical excision procedure(LEEP). Methods 165 cases of CIN Ⅱ~Ⅲpatients with HPV infection who underwent LEEP operation were randomly divided into observation group(n=83)and control group(n=82). In the observation group,patients were given a piece of EaLeSu in cervical wound at once in postoperative and two vaginal EaLeSu per day from the first postoperative day for eight consecutive days. The patients in the control group were treated with routine debridement and wound dressing with iodine. We observed the vaginal drainage times within 4 weeks after operative,bleeding rate,cervical wound repair,and cervical HPV DNA infection after 6 months. Results There were significant differences in the bleeding rate,vaginal drainage time,cervical wound repair and HPV DNA infection between the two groups(P < 0.05). Conclusion EaLeSu showed a definite effect on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with LEEP.
