Hydatidosis is the largest parasific disase in human being. The patients often contract hydatidosis in the childhood. The slow growth of hydatid cysts in the organ involved may lead to a protracted course of disease. In the early stage of the diseases, there are no distinct subjecive symptoms. Early diagnosis is difficult by routine examination. The complications of hydatidosis causing serious damage to the organs may often lead to sudden death. It is essential to make an early and correct diagnosis and give treatment. B-mode ultrasonography not only detects the location, dimension and chracteristics of hydatid cysts but also shows the pathological changes of the various complications caused by hydatidosis and faciliates to select the best program of operation. B-mode ulttasonography is the method of choice in the diagnosis of hydatidosis. In this series of 931 patients with hepatic hydatid disease, the diagnostic accuracy rate of B-mode ultrasonography reached 98. 8%.

Objective To study the risk factors for pathological upgrading after diagnosis of esophageal low?grade intra?epithelial neoplasia with ESD preoperative biopsy. Methods The endoscopic and pathological data of 85 lesions with ESD preoperative biopsy were analyzed, and grouped based on pathological upgrading after ESD. The risk factors for pathological upgrading after ESD was studied through single and multiple factor analysis. Results Pathological upgrading occurred in 45(52?94%) lesions after ESD, among whom 38 lesions developed up to high?grade intra?epithelial neoplasia and 7 lesions developed to esophageal early cancer. NBI?ME was performed on 37 patients and the accuracy of detecting the pathological invasion was 83?8%(31/37).Multi?factor analysis showed that reddish surface(OR=9?478, 95%CI:2?775?32?368, P = 0?000 3 ) and nodular lesion ( OR = 15?628, 95%CI:1?475?165?617, P =0?022 5) were independent factors for pathological upgrading after ESD. Conclusion Pathological upgrading of low?grade intra?epithelial neoplasia was common, especially esophageal mucosa with red surface and nodular lesion.Biopsy combined with NBI?ME is of significant importance to improve diagnostic accuracy.

Objective:To investigate the correlation between amide proton transfer-weighted (APTw) values and Ki-67 labeling index of cervical squamous cell carcinoma.Methods:From October 2017 to December 2018, 24 patients with cervical squamous cell carcinoma [International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ-Ⅲ] were prospectively enrolled in Peking Union Medical College Hospital and underwent pelvic morphological MRI on a 3.0 T MR scanner, including three-dimensional turbo-spin-echo APTw imaging and DWI. The maximum diameters of the lesions, APTw values and ADC values on the slice with the maximum diameter of the lesion were independently measured by two radiologists. The ICC was computed to evaluate the inter-observer consistency. Ki-67 immunohistochemical expression status was assessed by one pathologist. The Pearson correlation analysis was performed between the APTw values, maximum diameters, ADC values and Ki-67 labeling index.Results:The APTw values of cervical squamous cell carcinoma were (2.9±0.5)%. Inter-observer ICC was 0.972 (95%CI 0.937-0.988). The APTw values were positively moderately correlated with Ki-67 labeling index [(61.9±18.7)%, r=0.532, P=0.008]. The maximum diameters of the lesions were (28.7±10.6) mm. The mean ADC values were (0.998±0.217)×10 -3 mm 2/s. No correlations were found between maximum diameters, ADC values and Ki-67 labeling index ( r=0.038, P=0.859; r=0.238, P=0.263). Conclusion:APTw values can partially reveal the proliferation status of cervical squamous cell carcinoma.
