The paper summarizes the imaging evaluation methods for assessing the degree of carotid artery stenosis and analyzes the unique advantages and limitations of various imaging techniques in vascular imaging based on existing guidelines and consensus.The paper focuses on reviewing the clinical applications of several novel ultrasound technologies,including the use of advanced hemodynamic parameters such as blood flow dispersion(Tur index)and wall shear stress(WSS).Carotid artery stenosis is closely associated with cardiovascular disease.Although non-invasive and radiation-free ultrasound technology has certain limitations in diagnostic accuracy to a certain extent,with the continuous emergence of advanced functions such as ultrasound hemodynamics and vascular elasticity,the combination of multi-modality and multi-parameter ultrasound is expected to become an important method for efficient diagnosis of arterial stenosis in the future.

Objective To construct an integrated pharmaceutical care model for chronic respiratory system disease patients,and to provide policy recommendations.Methods A field survey,a semi-structured interview,and a questionnaire survey were comprehensively used to investigate the effect of the reform and the status quo of pharmaceutical care for chronic respiratory diseases after the medicine consistency reform in the medical alliance of Chongqing.Subsequently,the rainbow model was used to assess the challenges in the macro,meso,micro,and supporting element's dimensions,and the integrated pharmaceutical care model was established as a consequence.Results The primary issues involved in the medical alliance were as followed:insufficient joint reformation for public health services,medical insurance,and medical production and circulation(JRPMM);deficient supporting policies;a dearth of information support;an inadequately list of medications;insufficient collaboration among chronic disease specialties;and unstandardized pharmaceutical care.Consequently,the following recommendations were:in the macro dimension,to strengthen the JRPMM to enhance the service capacity of primary hospitals and to develop suitable human resource coordination mechanisms.In the meso dimension,to intensify the reform of pharmaceutical care in the medical alliance and enhance specialty collaboration horizontally.In the micro dimension,to establish a pharmaceutical management committee in the medical alliance,to formulate pharmaceutical technical specifications for the hierarchical medical system,and to combine"talent and technology"training innovatively.In the supporting elements dimension,to bolster information support in the area and to develop suitable incentives and assessment institutions.Conclusion This paper reported an integrated pharmaceutical care model for chronic respiratory diseases,which could serve as a reference for standardizing the hierarchical medical system for chronic diseases.

Objective:To explore the diagnostic value of contrast-enhanced mammography (CEM) and MRI in differentiating benign and malignant breast lesions based on the 2013 breast imaging reporting and data system (BI-RADS) lexicon and the supplement on CEM.Methods:The clinical and imaging data of 83 patients with breast lesions from March 2019 to April 2022 in the Third Affiliated Hospital of Soochow University were retrospectively analyzed. Totally 100 breast lesions from 83 female patients aged 28 to 78 (49±14) years, were divided into benign lesions (50 lesions) and malignant lesions (50 lesions) according to the pathological results. The t-test, χ 2 test and Fisher′s exact test were used to compare the differences of clinical and imaging features between benign and malignant lesions, and these imaging features which had statistical differences were established CEM and MRI models by multivariate logistic regression analysis respectively. The receiver operating characteristic curves and the area under the curve (AUC) were used to assess the diagnostic efficacy of two models in differentiating benign and malignant breast lesions. Using the DeLong test compared the AUC. Results:Multivariate logistic regression analysis showed that associated features (OR=9.075,95%CI 1.430-57.570, P=0.019), lesion conspicuity (OR=6.180,95%CI 2.608-14.646, P<0.001), mass margin (OR=2.193,95%CI 1.405-3.422, P=0.001) and calcification distribution (OR=2.147,95%CI 1.157-3.986, P=0.015) were independent predictors of differentiating benign and malignant breast lesions in CEM, and then the predictive model of CEM was constructed. Time-signal intensity curve (OR=9.230, 95%CI 3.178-26.805, P<0.001), associated features (OR=5.289,95%CI 1.343-20.831, P=0.017) and mass margin (OR=2.192,95%CI 1.336-3.597, P=0.002) were independent predictors of differentiating benign and malignant breast lesions in MRI, and the predictive model of MRI was constructed. The AUC of CEM and MRI models for differentiating benign and malignant breast lesions were 0.947 and 0.930 respectively, and two models were no significant difference ( Z=0.68, P=0.494). Conclusion:The diagnostic efficacy of CEM and MRI in differentiating benign and malignant breast lesions is comparable based on the 2013 BI-RADS lexicon and the supplement on CEM.

Objective:To discuss the diagnosis and treatment of ectopic ureter company with the bladder neck and urethral maldevelopment in children.Methods:The clinical data of the 6 patients admitted to Children’s Hospital affiliated to Chongqing Medical University from September 1993 to April 2019 diagnosed as ectopic ureter company with the bladder neck and urethral maldevelopment were retrospectively reviewed. The 6 children were girls and the median age was 7 years old , ranged from 2 to 15 years old. All children had ectopic ureter, including 3 in left-sided, 1 in right-sided, and 2 in bilateral-sided. Five children presented the intermittent dribbling incontinence and one child presented the continuously incontinence without normal voiding. Through ultrasound, IVP, MRI, cystoscopy and retrograde urography, seven ureters were found ectopic position, including bladder neck in 4 cases, two ureters inserted in the vagina in 2 cases. There were two cases with duplex kidney and 4 cases with renal dysplasia. Preoperative cystoscopy revealed wide and short urethra in 1 case, wide bladder neck combined with wide and short urethra in 4 cases. The surgery type included nephrectomy in cases 1-3, bilateral ureter reimplantation in case 4 who had the bilateral ectopic ureter , bilateral ureter reimplantation and bladder neck reconstruction at the same time in case 5. Nephrectomy associated with bladder neck and urethral reconstruction in case 6.Results:Five patients were followed-up and one patient was lost to follow-up after the first operation. Mean follow-up was 41.2 months (ranging 2 to 84 months). Four patients with bladder neck and maldevelopment that were not solved intraoperatively got reoperations due to incontinence without remission. Case 1, who underwent urethral reconstruction and extension, and urinary incontinence was partially relieved. Case 2 was found to have wide bladder neck deformity, and then retrospectively got bladder neck reconstruction and urethrovaginal fistula repair in 3 years and 5 years later. The urinary incontinence was completely relieved. The ureteral stump of case 3 was resected 2 years after operation due to recurrent urinary tract infection, and then got twice bladder neck and urethral reconstruction in 3 years and 6 years later of nephrectomy. His incontinence was partially relieved. The case 4 got bladder neck and urethral reconstruction in one year after bilateral ureter reimplantation, and incontinence was partially relieved too. Among the two patients underwent combined surgery, the case 5, who got bilateral ureteral bladder replantation combined with bladder neck reconstruction, were lost to follow-up after surgery. The case 6 got dysplasia nephrectomy combined with bladder neck reconstruction and urethroplasty were completely relieved of urinary incontinence.Conclusions:Bladder neck and urethra maldevelopment is one of the main causes of urinary incontinence after surgery in children with ectopic ureter. The diagnosis mainly relies on cystoscopy. The treatment mainly relies on surgery. Bladder neck and urethral reconstruction is expected to be available. If the operative conditions permit, synchronous surgical treatment of ectopic ureter and bladder neck and urethral maldevelopment will get a better prognosis than staging surgery.
