Objective To analyze the characteristics of published radiology original articles in China,and compare radiology research inboard and abroad.Methods According to the Contents of Chinese Science Core Periodicals in 2012,there were 15 comprehensive radiological core periodicals in China.All of them were retrospectively surveyed,and original articles published between October 2011 and October 2012were evaluated.The following information was abstracted from each article:radiologic technique used,radiologic subspeciahy,type of research,sample size and study design.At the same time,all the original articles from two top radiology journals,Radiology and European Radiology (ER) at the same period were evaluated.Chi-square test was used to compare the composition percentage inboard and abroad.Results There were 2784 original articles published in the 15 Chinese top radiological periodicals in total The most commonly used radiologic techniques were CT (1093 of 2784,39.3％),MRI (824 of 2784,29.6％) and intervention (402 of 2784,14.4％).Radiology and ER totally published 560 original articles.MRI (265 of 560,47.3％),CT (170 of 560,30.4％) and mixed techniques (63 of 560,11.3％) were most used.In China,as much as 2572 (92.4％) articles were clinical research,115 (4.1％) was basic research,9 (0.3％) was clinical and basic research,and 83 (3.2％) was non-basic non-clinical research.The sample size of less than 10,between 10 to 50,and more than 50 was 374 (13.4％),1448 (52.0％) and 847 (30.4％) respectively.339 (12.2％) Chinese articles belonged to perspective research,and 1211 (43.5％) were retrospective.For Radiology and ER,515 (92.0％) articles were clinical research,39 (7.0％) was basic research,3(0.5％) was clinical and basic research,and 3(0.5％) was non-basic non-clinical.The sample size of less than I0,between 10 to 50,and more than 50 was 30 (5.4％),225 (40.2％) and 252 (45.0％) respectively.230 (41.1％) articles belonged to perspective research,and 202 (36.1％) ones were retrospective.Radiology and ER articles used MRI more than that published in Chinese radiology journals (x2 =666.690,P ＜ 0.01).Clinical research was the most commonly used research type both inboard and abroad (x2 =0.116,P ＞0.05).Articles of sample size more than 50 abroad were more than that of China (x2 =44.895,P ＜0.01).Perspective research was used more abroad (x2 =275.667,P ＜ 0.01),and the main research type in China was retrospective.Conclusion Chinese radiology workers might need to do more perspective and larger sample size clinical researches.

Objective To explore the clinical and aesthetic results of single axillary approach reverse sequence endoscopic nipple-sparing mastectomy of breast cancer combined with subpectoral implant-based breast reconstruction (IBBR) for breast cancer patients. Methods The clinical data of consecutive female patients who underwent single axillary approach reverse sequence endoscopic nipple-sparing mastectomy of breast cancer combined with subpectoral IBBR from May 2020 to December 2022 were retrospectively analyzed. The patient demographics, perioperative parameters, complications and aesthetic results were collected. Results A total of 62 patients (74 breasts) were included. The mean age of patients was (39.0±7.8) years. The total mean operation time was (185.2±45.5) minutes. Five (8.1%) patients suffered from surgical complications. Two (3.2%) patients experienced major complications, and 3 (4.8%) suffered from minor complications. No patient experienced partial nipple-areola complex necrosis. Seventeen (27.4%) patients experienced implant related complications, of which 11 (17.7%) experienced capsular contracture. During a median follow-up time of 30 months ranging from 11 to 42 months, no patient experienced locoregional recurrence, distant metastasis or death. Thirty-seven (88.1%) patients evaluated their breasts as good or excellent. In the surgeon-reported cosmetic results, 40 (95.2%) patients achieved excellent or good results. Conclusion This surgical technique is characterized by minimal trauma, short operation time, high safety, and excellent cosmetic outcomes for patients with small breasts and mild ptosis, making it worthy of further promotion.
