2A study of the efficacy of bacterial biofilm cleanout for gastrointestinal endoscopes显示文摘AIM:To compare the influence and clearance effect of enzymatic and non-enzymatic detergents against Escherichia coli (E. coli) biofilm on the inner surface of gastroscopes.METHODS:Teflon tubes were incubated in a mixture of different detergents and E. coli culture (106 CFU/mL) for 72 h at 15℃,and biofilms on the inner surface of the teflon tubes were analyzed by bacterial count and scanning electron microscopy. To evaluate the clear-ance effect of detergents,after biofilms were formed on the inner surface of Teflon tubes by 72 h lavage with E. coli culture,tubes were lavaged by enzymatic and non-enzymatic detergents at a speed of 250 mL/min,then biofilms on the inner surface were analyzed by bacterial count and scanning electron microscopy.RESULTS:Non-enzymatic detergent had a better inhi-bition function on biofilm formation than enzymatic de-tergent as it reduced bacterial burden by 2.4 log compared with the control samples (P = 0.00). Inhibition function of enzymatic detergent was not significantly different to that of control samples and reduced bac-terial burden by 0.2 log on average (P > 0.05). After lavaging at 250 mL/min for 3 min,no living bacteria were left in the tubes. Scanning electron microscopy observation showed biofi lms became very loose by the high shear force effect. CONCLUSION:Non-enzymatic detergent has a better inhibition effect on biofilm formation at room temperature. High speed pre-lavage and detergents are very important in temporal formed biofilm elimination.Fang, Ying Shen, Zhe Li, Lan Cao, Yong Gu, Li-Ying Gu, Qing Zhong, Xiao-Qi Yu, Chao-Hui Li, You-Ming 2010World Journal of Gastroenterology2010,16,8:28
3Sequencing of Cultivated Peanut, Arachis hypogaea, Yields Insights into Genome Evolution and Oil Improvement显示文摘Cultivated peanut (Arachis hypogaea) is an allotetraploid crop planted in Asia, Africa, and America for edible oil and protein. To explore the origins and consequences of tetraploidy, we sequenced the allotetraploid A. hypogaea genome and compared it with the related diploid Arachis duranensis and Arachis ipaensis genomes. We annotated 39 888 A-subgenome genes and 41 526 B-subgenome genes in allotetraploid peanut. The A. hypogaea subgenomes have evolved asymmetrically, with the B subgenome resembling the ancestral state and the A subgenome undergoing more gene disruption, loss, conversion, and transposable element proliferation, and having reduced gene expression during seed development despite lacking genome-wide expression dominance. Genomic and transcriptomic analyses identified more than 2 500 oil metabolism-related genes and revealed that most of them show altered expression early in seed development while their expression ceases during desiccation, presenting a comprehensive map of peanut lipid biosynthesis. The availability of these genomic resources will facilitate a better understanding of the complex genome architecture, agronomically and economically important genes, and genetic improvement of peanut.Xiaoping Chen Qing Lu Hao Liu Jianan Zhang Yanbin Hong Haofa Lan Haifen Li Jinpeng Wang Haiyan Liu Shaoxiong Li Manish K.Pandey Zhikang Zhang Guiyuan Zhou Jigao Yu Guoqiang Zhang Jiaqing Yuan Xingyu Li Shijie Wen Fanbo Meng Shanlin Yu Xiyin Wang Kadambot H.M.Siddique Zhong-Jian Liu Andrew H.Paterson Rajeev K.Varshney Xuanqiang Liang 2019Molecular Plant2019,12,7:23

6宣威肺癌分子流行病学研究:煤种、基因型与肺癌风险显示文摘背景与目的已有的研究证明:宣威是我国农村肺癌死亡率最高的地区,肺癌危险与室内燃烧烟煤产生的多环芳烃(polycyclic aromatic hydrocarbons,PAHs)有关,肺癌发病具有明显的地域性差别和家族聚集性。本研究从分子流行病学角度探索宣威肺癌风险的危险因素及与发病机理有关的基因型和燃煤类型。方法运用两个基于人群的病例对照研究,开展问卷调查,同时采集口腔细胞和痰等生物样品,提取DNA。应用PCR法检测GST超家族、AKR超家族和OGG1等基因型。通过Logistic回归分析煤种、基因型与肺癌风险的关联。结果与燃用无烟煤或木柴的研究对象相比,家用来宾烟煤的肺癌风险比数比(odds ratio,OR)值高达24.8,其次为龙潭(OR=11.6)、宝山(OR=6.0)、龙场(OR=4.1)、羊场(OR=3.8)等;燃用同种烟煤的男女肺癌风险相似。对于GSTM1缺失、AKR1C3(Ex1-70C>G)、OGG1(Ex6-315C>G)基因型,肺癌风险明显增高,且具统计学意义[OR(95%CI)分别为2.3(1.3-4.2)、1.8(1.0-3.5)和1.9(1.1-3.3)]。与家用烟煤量小且具GSTM1阳性的研究对象相比,用量大且GSTM1缺失的研究对象肺癌风险更高,女性OR为4.9(1.3-18.2),男性OR为2.7(1.0-7.4)。但对于AKR1C3(Ex1-70C>G)和OGG1(Ex6-315C>G),仅观察到女性肺癌风险的明显增高,OR分别为12.9(2.2-107.8)和5.7(1.1-34.2)。结论宣威不同煤种的肺癌风险有很大差异,但暴露于相同煤种的男性与女性肺癌风险相似。GSTM1缺失基因型与肺癌风险增高有关联。AKR1C3与OGG1这2种基因型与肺癌风险有关联,且在烟煤使用量高的女性中肺癌风险更高。李继华 何俊 唐锐 Wei HU Qing LAN 何兴舟 李云 张云生 2015中国肺癌杂志2015,18,1:19
7QTL editing confers opposing yield performance in different rice varieties显示文摘Grain yield is one of the most important and complex trait for genetic improvement in crops; it is known to be controlled by a number of genes known as quantitative trait loci(QTLs). In the past decade, many yield-contributing QTLs have been identified in crops.However, it remains unclear whether those QTLs confer the same yield performance in different genetic backgrounds. Here, we performed CRISPR/Cas_9-mediated QTL editing in five widely-cultivated rice varieties and revealed that the same QTL can have diverse, even opposing, effects on grain yield in different genetic backgrounds.Lan Shen Chun Wang Yaping Fu Junjie Wang Qing Liu Xiaoming Zhang Changjie Yan Qian Qian Kejian Wang 2018Journal of Integrative Plant Biology2018,60,2:18
8Contrast-enhanced ultrasound improved performance of breast imaging reporting and data system evaluation of critical breast lesions显示文摘AIM: To determine whether contrast-enhanced ultrasound(CEUS) can improve the precision of breast imaging reporting and data system(BI-RADS) categorization. METHODS: A total of 230 patients with 235 solid breast lesions classified as BI-RADS 4 on conventional ultrasound were evaluated. CEUS was performed within one week before core needle biopsy or surgical resection and a revised BI-RADS classification was assigned based on 10 CEUS imaging characteristics. Receiver operating characteristic curve analysis was then conducted to evaluate the diagnostic performance of CEUS-based BI-RADS assignment with pathological examination as reference criteria. RESULTS: The CEUS-based BI-RADS evaluation classified 116/235(49.36%) lesions into category 3, 20(8.51%), 13(5.53%) and 12(5.11%) lesions into categories 4A, 4B and 4C, respectively, and 74(31.49%) into category 5. Selecting CEUS-based BI-RADS category 4A as an appropriate cut-off gave sensitivity and specificity values of 85.4% and 87.8%, respectively, for the diagnosisof malignant disease. The cancer-to-biopsy yield was 73.11% with CEUS-based BI-RADS 4A selected as the biopsy threshold compared with 40.85% otherwise, while the biopsy rate was only 42.13% compared with 100% otherwise. Overall, only 4.68% of invasive cancers were misdiagnosed.CONCLUSION: This pilot study suggests that evaluation of BI-RADS 4 breast lesions with CEUS results in reduced biopsy rates and increased cancer-to-biopsy yields.Jun Luo Ji-Dong Chen Qing Chen Lin-Xian Yue Guo Zhou Cheng Lan Yi Li Chi-Hua Wu Jing-Qiao Lu 2016World Journal of Radiology2016,8,6:17

10Dihydromyricetin alleviates carbon tetrachloride-induced acute liver injury via JNK-dependent mechanism in mice显示文摘AIM: To assess the effects of dihydromyricetin(DHM) as a hepatoprotective candidate in reducing hepatic injury and accelerating hepatocyte proliferation after carbon tetrachloride(CCl4) treatment.METHODS: C57 BL/6 mice were used in this study. Mice were orally administered with DHM(150 mg/kg) for 4 d after CCl4 treatment. Serum and liver tissue samples were collected on days 1, 2, 3, 5 and 7 after CCl4 treatment. The anti-inflammatory effect of DHM was assessed directly by hepatic histology detection and indirectly by serum levels of aspartate aminotransferase(AST), alanine aminotransferase(ALT), albumin, and superoxide dismutase(SOD). Inflammatory cytokines, such as interleukin(IL)-1β, IL-6 and tumor necrosis factor-α(TNF-α), were detected using ELISA kits. Proliferating cell nuclear antigen(PCNA) staining was used to evaluate the role of DHM in promoting hepatocyte proliferation. Hepatocyte apoptosis wasmeasured by TUNEL assay.Furthermore,apoptosis proteins Caspases-3,6,8,and 9 were detected by Western blot.SP600125 were used to confirm whether DHM regulated liver regeneration through JNK/TNF-αpathways.RESULTS:DHM showed a strong anti-inflammatory effect on CCl4-induced liver injury in mice.DHM could significantly decrease serum ALT,AST,IL-1β,IL-6 and TNF-αand increase serum albumin,SOD and liver SOD compared to the control group after CCl4 treatment(P<0.05).PCNA results indicated that DHM could significantly increase the number of PCNA positive cells compared to the control(348.9±56.0 vs 107.1±31.4,P<0.01).TUNEL assay showed that DHM dramatically reduced the number of apoptotic cells after CCl4 treatment compared to the control(365.4±99.4 vs 90.5±13.8,P<0.01).Caspase activity detection showed that DHM could reduce the activities of Caspases-8,3,6 and 9 compared to the control(P<0.05).The results of Western blot showed that DHM increased the expression of JNK and decreased TNF-αexpression.However,DHM could not affect TNF-αexpression after SP600125 treatment.Furthermore,DHM could significantly improve the survival rate of acute liver failure(ALF)mice(73.3%vs 20.0%,P<0.0001),and SP600125 could inhibit the effect of DHM.CONCLUSION:These findings demonstrate that DHM alleviates CCl4-induced liver injury,suggesting that DHM is a promising candidate for reversing liver injury and ALF.Jun Xie Jie Liu Tu-Ming Chen Qing Lan Qing-Yu Zhang Bin Liu Dong Dai Wei-Dong Zhang Li-Ping Hu Run-Zhi Zhu 2015World Journal of Gastroenterology2015,21,18:17
11Household air pollution and lung cancer in China:a review of studies in Xuanwei显示文摘Over half of the world's population is exposed to household air pollution from the burning of solid fuels at home. Household air pollution from solid fuel use is a leading risk factor for global disease and remains a major public health problem, especially in low- and mid-income countries. This is a particularly serious problem in China, where many people in rural areas still use coal for household heating and cooking. This review focuses on several decades of research carried out in Xuanwei County, Yunnan Province, where household coal use is a major source of household air pollution and where studies have linked household air pollution exposure to high rates of lung cancer. We conducted a series of case-control and cohort studies in Xuanwei to characterize the lung cancer risk in this population and the factors associated with it. We found lung cancer risk to vary substantially between different coal types, with a higher risk associated with smoky(i.e., bituminous) coal use compared to smokeless(i.e., anthracite) coal use. The installation of a chimney in homes resulted in a substantial reduction in lung cancer incidence and mortality. Overall, our research underscores the need among existing coal users to improve ventilation, use the least toxic fuel, and eventually move toward the use of cleaner fuels, such as gas and electricity.Wei Jie Seow Wei Hu Roel Vermeulen H.Dean Hosgood III George S.Downward Robert S.Chapman Xingzhou He Bryan A.Bassig Christopher Kim Cuiju Wen Nathaniel Rothman Qing Lan 2014Chinese Journal of Cancer2014,33,10:15
12Toward a stepwise Kwangsian Orogeny显示文摘The Kwangsian Orogeny originated along the southeast coast of China and stepwise developed in a northwest direction.It includes two stages,a long locally varying uplift from the Late Ordovician to the early Silurian and a finally tectonic movement near the Silurian and Devonian transition.The Kwangsian uplift event shows a stepwise delay northwestwards from the southeastern coast area in Nemagraptus gracilis Biozone(Sa1)to the south side of the Xuefeng Mountains in or later than Cystograptus vesiculosus Biozone(R3)to Coronograptus cyphus Biozone(R4).In the southern of Yangtze Platform,the Yichang Uplift was droved by the Kwangsian Orogeny forming a diachronous stratigraphical break through Rhuddanian and Aeronian.The distribution of the early Telychian lower marine red beds indicates a northwestward increase of the Cathaysian Oldland.Stratigraphical evidence may explain why the Kwangsian movement was marked by an angular disconformity during the Pridoli to earliest Devonian interval.CHEN Xu FAN JunXuan CHEN Qing TANG Lan HOU XuDong 2014Science China Earth Sciences2014,57,3:13
13Influence of disodium hydrogen phosphate dodecahydrate on hydrothermal formation of hemihydrate calcium sulfate whiskers显示文摘The influence of Na_2HPO_4·12H_2O on the hydrothermal formation of hemihydrate calcium sulfate(CaSO_4·0.5H_2O) whiskers from dihydrate calcium sulfate(CaSO_4·2H_2O)at 135 ℃ was investigated.Experimental results indicate that the addition of phosphorus accelerates the hydrothermal conversion of CaSO_4·2H_2O to CaSO_4·0.5H_2O via the formation of Ca_3(PO_4)_2 and produces CaSO_4-0.5H_2O whiskers with thinner diameters and shorter lengths.Compared with the blank experiment without Na_2HPO_4·12H_2O,the existence of minor amounts(8.65 ×10^(-4)-4.36 × 10^(-3) mol/L) of Na_2HPO_4·12H_2O led to a decrease in the diameter of CaSO_4·0.5H_2O whiskers from 1.0-10.0 to 0.5-2.0 μm and lengths from 70-300 to50-200 μm.Qing Han Kangbi Luo Huping Li Lan Xiang 2014Particuology2014,12,6:13
14Risk Factors for Lung Cancer in Non-smokers in Xuanwei County of China显示文摘Tobacco smoking and some types of occupational exposures have consistently been considered as important etiologic factors of lung cancer in industrial countrie.At the First World Conference of Lung Cancer(Wyndwer,1983),it was stressed that more attention should be paid to finding out the causes of lung cancer in non-smokers. In Xuanwei County,Yunnan Province,annual lung cancer death rate was 27.7per 100,000 in males,among China's highest,and 25.3per 100,000 in females,the China's highest.The remale's lung cancer death rate in Xuanwei County was even much higher than that of the same period in USA white women(ECACM,1979;Mulvihill,1976),Marked district variation in cancer mortality exists within xuanwei County.The county can be ivided into high-,medium-and low-mortality areas.Over90% of the population are farmers.The local residents traditionally burned three major kinds of fuels:“smoky” coal,“smokeless”coal and “wood”,for heating and cooking.The three lung cancer high mortality areas,including “Chengguan”,“Rongcheng”and “Laibin”communes,mainly burned the “smoky”!coal from Laibin smoky-coal mine.The fuel was burned in a shallow,unventiated fire pit in the floor of the dwelling.Fuel burning in shallow unventialated pits has resulted in high indoor air pollution levels.The concentrations of airborne particles(pm10) inside houses during smoky coal and wood combustion were very high.Indoor concentration of suspended particulates and dichloromethane extractable organics were 244.4mg/m^3 and 17.6mg/m^3 in burning of “smoky”coal;22.2mg/m^3,12.3mg/m^3 for burning wood;and 1.8mg/m^3,0.5mg/m^3 for burning of smokeless coals.Levels of individual polycyclic aromatic hydrocarbons.including benzo(a)pyrene,were generally highest during burning of smoky coal,intermediate in burning wood,and least in smokeless coal.Women did most household chores.which include starting fire and cooking.Less than 0.2% of females smoked tobacco.The population-based casecontrol study presented here is to evaluate the influence of factors on the occurrence of lung cancer in non-smoking women in Xuanwei County and to supplement the etiologic factors of lung cancer in Xuanwei County.LAN QING, CHEN WEI, CHEN HONG, AND HE XING-ZHOUInstitute of Environmental Health and Engineering, Chinese Academy of Preventive Medicine 29 Nan Wei Road, Beijing 100050, China 1993Biomedical and Environmental Sciences1993,6,2:13

16Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13
17Trabecular-like Ti-6Al-4V scaffolds for orthopedic: fabrication by selective laser melting and in vitro biocompatibility显示文摘Porous metal scaffolds play an important role in the orthopedic field, due to their wide applications in prostheses implantation. Some previous studies showed that the scaffolds with trabecular bone structure reconstructed via computed tomography had satisfactory biocompatibility. However, the reverse modeling scaffolds were inflexible for customized design. Therefore, a top-down designing biomimetic bone scaffold with favorable mechanical performances and cytocompatibility is urgently demanded for orthopedic implants. An emerging additive manufacturing technique, selective laser melting, was employed to fabricate the trabecular-like porous Ti-6Al-4 V scaffolds with varying irregularities(0.05-0.5) and porosities(48.83%–74.28%) designed through a novel Voronoi-Tessellation based method. Micro-computed tomography and scanning electron microscopy were used to characterize the scaffolds’ morphology.Quasi-static compression tests were performed to evaluate the scaffolds’ mechanical properties. The MG63 cells culture in vitro experiments, including adhesion, proliferation, and differentiation, were conducted to study the cytocompatibility of scaffolds. Compressive tests of scaffolds revealed an apparent elastic modulus range of 1.93–5.24 GPa and an ultimate strength ranging within 44.9–237.5 MPa, which were influenced by irregularity and porosity, and improved by heat treatment. Furthermore, the in vitro assay suggested that the original surface of the SLM-fabricated scaffolds was favorable for osteoblasts adhesion and migration because of micro scale pores and ravines. The trabecular-like porous scaffolds with full irregularity and higher porosity exhibited enhanced cells proliferation and osteoblast differentiation at earlier time, due to their preferable combination of small and large pores with various shapes. This study suggested that selective laser melting-derived Ti-6Al-4 V scaffold with the trabecular-like porous structure designed through Voronoi-Tessellation method, favorable mechanical performance, and good cytocompatibility was a potential biomaterial for orthopedic implants.Huixin Liang Youwen Yang Deqiao Xie Lan Li Ning Mao Changjiang Wang Zongjun Tian Qing jiang Lida Shen 2019Journal of Materials Science & Technology2019,35,7:12
18Developing disease-resistant thermosensitive male sterile rice by multiplex gene editing显示文摘High-quality and disease-resistant male sterile lines have great potential for applications in hybrid rice breeding.We introduced specific mutations into the TMS5,Pi21,and Xa13 genes in Pinzhan intermediate breeding material using the CRISPR/Cas9 multiplex genome editing system.We found that the transgenefree homozygous triple tms5/pi21/xa13 mutants obtained in the T1 generation displayed characteristics of thermosensitive genic male sterility(TGMS)with enhancedresistance to rice blast and bacterial blight.Our study provides a convenient and effective way of converting breeding intermediate material into TGMS lines through multiplex gene editing,which could significantly accelerate the breeding of sterile lines.Sanfeng Li Lan Shen Ping Hu Qing Liu Xudong Zhu Qian Qian Kejian Wang Yuexing Wang 2019Journal of Integrative Plant Biology2019,61,12:11
19Rapid generation of genetic diversity by multiplex CRISPR/Cas9 genome editing in rice显示文摘The clustered regularly interspaced short palindromic repeats(CRISPR)-associated endonuclease 9(CRISPR/Cas9) system has emerged as a promising technology for specific genome editing in many species. Here we constructed one vector targeting eight agronomic genes in rice using the CRISPR/Cas9 multiplex genome editing system. By subsequent genetic transformation and DNA sequencing, we found that the eight target genes have high mutation efficiencies in the T_0 generation. Both heterozygous and homozygous mutations of all editing genes were obtained in T_0 plants. In addition, homozygous sextuple, septuple, and octuple mutants were identified. As the abundant genotypes in T_0 transgenic plants, various phenotypes related to the editing genes were observed. The findings demonstrate the potential of the CRISPR/Cas9 system for rapid introduction of genetic diversity during crop breeding.Lan Shen Yufeng Hua Yaping Fu Jian Li Qing Liu Xiaozhen Jiao Gaowei Xin Junjie Wang Xingchun Wang Changjie Yan Kejian Wang 2017Science China(Life Sciences)2017,60,5:11
20Predictive model for contrast-enhanced ultrasound of the breast: Is it feasible in malignant risk assessment of breast imaging reporting and data system 4 lesions?显示文摘AIM: To build and evaluate predictive models for contrast-enhanced ultrasound(CEUS) of the breast to distinguish between benign and malignant lesions. METHODS: A total of 235 breast imaging reporting and data system(BI-RADS) 4 solid breast lesions were imaged via CEUS before core needle biopsy or surgical resection. CEUS results were analyzed on 10 enhancing patterns to evaluate diagnostic performance of three benign and three malignant CEUS models, with pathological results used as the gold standard. A logistic regression model was developed basing on the CEUS results, and then evaluated with receiver operating curve(ROC). RESULTS: Except in cases of enhanced homogeneity, the rest of the 9 enhancement appearances were statistically significant(P < 0.05). These 9 enhancement patterns were selected in the final step of the logistic regression analysis, with diagnostic sensitivity and specificity of 84.4% and 82.7%, respectively, and the area under the ROC curve of 0.911. Diagnostic sensitivity, specificity, and accuracy of the malignant vs benign CEUS models were 84.38%, 87.77%, 86.38% and 86.46%, 81.29% and 83.40%, respectively. CONCLUSION: The breast CEUS models can predict risk of malignant breast lesions more accurately, decrease false-positive biopsy, and provide accurate BIRADS classification.Jun Luo Ji-Dong Chen Qing Chen Lin-Xian Yue Guo Zhou Cheng Lan Yi Li Chi-Hua Wu Jing-Qiao Lu 2016World Journal of Radiology2016,8,6:10
