Objective To compare the diagnostic value of digital breast tomosynthesis (DBT), digital mammography(DM),and ultrasonography(US)for the non-calcified ductal carcinoma in situ(DCIS) of the breast.Methods To retrospectively analyze the imaging and clinical data of ductal carcinoma in situ which was confirmed by surgical pathology and displayed as non-calcified lesions in mammography in 110 patients.DBT,DM and US were performed in all the 110 cases.The breast imaging report and data system (BI-RADS)classification and breast density classification were evaluated using the 5th edition of BI-RADS. In our study, BI-RADS 4B, 4C, and 5 were regarded to be in agreement with the pathologic findings, BI-RADS 1,2,3,and 4A were considered to be negative.BI-RADS c and d were classified as dense breasts, BI-RADS a and b were classified as fatty breasts.The imaging findings of the non-calcified ductal carcinoma in situ were evaluated.The differences in the detection rate and the diagnostic accuracy among the DBT,DM and US in all cases and in different breast density were compared using χ2 test. Results The detection rates of DBT,DM,and US for non-calcified DCIS in all cases were 84.5%(93/110),70.9%(78/110),95.5% (105/110).Pairwise comparisons among the three techniques showed statistically significant difference(P<0.05). The diagnostic accuracy of DBT, DM, and US were 70.0% (77/110), 44.5% (49/110), and 69.1% (76/110),respectively.The diagnostic accuracy of DBT and US were significantly higher than that of DM(P<0.01). Of the 110 patients, 89 patients were classified as dense breasts and non-dense breasts in the remaining 21 patients.The detection rates of DBT,DM,and US for non-calcified DCIS in dense breasts were 82.0%(73/89),65.2%(58/89),and 96.6%(86/89).Pairwise comparisons among the three techniques showed statistically significant difference(P<0.01).The diagnostic accuracy of DBT,DM,and US for non-calcified DCIS in dense breast were 65.2% (58/89), 38.2% (34/89) and 66.3% (59/89), respectively.The diagnostic accuracy of DBT and US were significantly higher than that of DM in dense breast(P<0.01).The detection rate and diagnostic accuracy for DBT,DM,and US in non-dense breasts were not statistically different(P>0.05).By DBT and DM,most cases of non-calcified DCIS presented as a mass lesion with an irregular shape, indistinct margin,and isodense composition.Conclusion US is more advantageous to the detection of the non-calcified DCIS and the non-calcified DCIS in the dense breast.

Objective:To analyze the clinical characteristics and management strategies of the patients who were injured in winter snow sports in parts of Qingdao in order to provide useful information for "300 million people participating in ice and snow sports" .Methods:A retrospective study was conducted to analyze the data of 128 patients who had been admitted to Department of Orthopaedics, Qingdao Central Hospital for skiing injuries from November 2019 to March 2021. The gender, type, location and cause of injury, and treatment method of the patients were statistically analyzed.Results:Of the 128 patients, 72 were males and 56 females with an age of (32.0±12.1) years. Single injury accounted for 97.66% (125/128) while multiple injuries 2.34% (3/128). 46 injuries (35.11%, 46/131) due to single board skiing occurred in 44 patients (34.38%, 44/128); 85 injuries (64.89%, 85/131) due to double board skiing occurred in 84 cases (65.62%, 84/128). As for injury types, there were 44 cases (34.38%, 44/128) of soft tissue injury and 84 fractures (65.62%, 84/128). The top 3 injured locations were the lower leg (24.43%, 32/131), the peri-wrist part (18.32%, 24/131), and the peri-knee part (15.27%, 20/131). The most vulnerable location was, respectively, the wrist joint (26.09%, 12/46) in single board skiing and the calf (31.76%, 27/85) in double board skiing. The top three causes of injury were accidental fall (39.06%, 50/128), being struck by someone or emergency evacuation (14.84%, 19/128), and mismatched equipment models (12.50%, 16/128). The proportion of skiing beginners was as high as 76.56% (98/128). Surgical treatment was performed in 49 cases (38.28%, 49/128), and conservative treatment in 79 cases (61.72%, 79/128).Conclusions:The clinical characteristics of the patients who were injured in winter snow sports in parts of Qingdao are high proportions of skiing beginners, falls and fractures. Special attention needs to be paid to wrist protection in single board skiing and checking the ski disengagement device before double board skiing. Most patients may need only conservative treatment because although a number of patients required surgical treatment, severe multiple injuries were rare.

Objective To analyze the clinical value of digital breast tomosynthesis (DBT) compared with digital mammography (DM) and ultrasound for diagnosing non-calcified masses in dense breasts.Methods Images taken with DBT,DM and ultrasound of 1144 patients with non-calcified masses in dense breasts were retrospectively analyzed using breast imaging reporting and data system (BI-RADS).Taking histopathologic results as golden standards,the detection rate and diagnostic accuracy,sensitivity,specificity,false negative and BI-RADS category were evaluated and compared statistically.Results The detection rate of DBT,DM and ultrasound for non-calcified massed in dense breasts was 86.62％ (991/1 144),77.80％ (890/1 144) and 99.65％ (1 140/1 144),respectively (P＜0.05),while the diagnostic accuracy was 83.92％ (960/1 144),75.00％ (858/1 144) and 94.67％ (1 083/1 144),respectively (P＜0.01).The sensitivity of DBT,DM and ultrasound was 89.39％ (312/349),79.93％ (231/289) and 92.70％ (432/466),the specificity was 81.51％ (648/795),73.33％ (627/855) and 96.02％ (651/678),while the false negative rate was 10.60％(37/349),20.07％ (58/289) and 7.30％ (34/466),respectively.No significant difference was found for benign lesions among three examination methods (P=0.75),while there was significant difference for malignant lesions among three examination methods (P＜0.01),and the differences of ultrasonography with DM and DBT,DBT and DM in the for BI-RADS category of malignant lesions were statistically significant (all P＜0.016 7).Conclusion For suspected masses in dense breasts,DBT shows significant advantage than DM,while DBT has the similar advantage compared with ultrasound for the detection and diagnosis of non-calcified masses in dense breasts.

Objective:To construct a prediction model for the prognosis of breast cancer patients with long non-coding RNA expression characteristics.Methods:To construct a long non-coding RNA(LncRNA) model for predicting the prognosis of breast cancer patients.Methods Analyzing LncRNA expression profiles and clinical characteristics of 1 081 breast cancer patients in the cancer genome atlas (TCGA) database.Performing differential expression analysis and univariate analysis on 112 paired breast cancer and normal breast tissues′ transcriptome sequencing data in the TCGA database, and screened for differentially expressed (DELncRNAs) that significantly correlated with the prognosis of BRCA (To reduce batch effects, sequencing data has been normalized using the DESeq function). One thousand eighty-one breast cancer patients were randomly divided into two groups: training set (541) and validation set (540). Performing Cox proportional hazard regression using DELncRNAs and establishing a multi-LncRNA prognosis model in the training set, followed by proportional hazards assumption test(PH assumption test). Patients were divided into high-risk and low-risk groups based on calculated risk score.Kaplan-Meier method was used for survival analysis, and 540 patients′ data were used for validation.To evaluate the prognostic value of the model in patients with squamous cell carcinoma of the lung and hepatocarcinoma in TCGA database.Gene Set Enrichment Analysis (GSEA) was used to analyze the specific mechanism of lncrna affecting the survival of patients.Results:There were 2815 differentially expressed genes screened by transcriptome sequencing, 91 of which were significantly related to the prognosis of breast cancer patients ( P<0.05). Based on the Cox regression analysis of 91 delncrna expression data from 541 breast cancer patients in training set, a Cox proportional risk regression model was constructed based on 5 LncRNA (training set AUC=0.746, validation set AUC=0.650): AC004551.1, MTOR-AS1, KCNAB1-AS2, FAM230G and LINC01283, and PH assumption test( P=0.388). K-M survival analysis showed that the survival time of high-risk group was significantly worse than that of low-risk group (median survival time: 7.049 and 12.21 years, HR 0.367, 95% CI0.228-0.597, P<0.001), and the survival time of high-risk group was significantly shorter than that of low-risk group (median survival time: 7.57 and 10.85 years, HR 0.412, 95% CI0.214-0.793, P<0.001). Similar prediction results were also obtained in other cancer species of TCGA: lung squamous cell carcinoma ( HR 0.604, 95% CI0.383-0.951, P=0.007) and liver cell carcinoma ( HR 0.551, 95% CI0.307-0.987, P=0.011). GSEA results suggested that the expression patterns of the above five LncRNA were related to the cell cycle regulation of tumor cells. Conclusion:The prognostic model constructed based on expression profile of AC004551.1, MTOR-AS1, KCNAB1-AS2, FAM230G and LINC01283 can be used to predict the prognosis of breast cancer patients, which is helpful to further guide clinical treatment.
