| 3 | Artificial intelligence in medical imaging of the liver显示文摘Artificial intelligence(AI), particularly deep learning algorithms, is gaining extensive attention for its excellent performance in image-recognition tasks. They can automatically make a quantitative assessment of complex medical image characteristics and achieve an increased accuracy for diagnosis with higher efficiency. AI is widely used and getting increasingly popular in the medical imaging of the liver, including radiology, ultrasound, and nuclear medicine. AI can assist physicians to make more accurate and reproductive imaging diagnosis and also reduce the physicians' workload. This article illustrates basic technical knowledge about AI, including traditional machine learning and deep learning algorithms, especially convolutional neural networks, and their clinical application in the medical imaging of liver diseases, such as detecting and evaluating focal liver lesions, facilitating treatment, and predicting liver treatment response. We conclude that machine-assisted medical services will be a promising solution for future liver medical care. Lastly, we discuss the challenges and future directions of clinical application of deep learning techniques. | Li-Qiang Zhou Jia-Yu Wang Song-Yuan Yu Ge-Ge Wu Qi Wei You-Bin Deng Xing-Long Wu Xin-Wu Cui Christoph F Dietrich | 2019 | World Journal of Gastroenterology2019,25,6: | 21 |
| 4 | Dynamic and ultrastructural study of sphincter of Oddi in early-stage cholelithiasis in rabbits with hypercholesterolemia显示文摘AIM To study the relationship between pre-formation of gallstone and the kinetics and ultra-structure of sphincter of Oddi.METHODS Adult female rabbits were used anddivided into 3 groups,and fed with either normalor high cholesterol diet for four or eight weeks.Each group contained eight rabbits.Themanometry of sphincter of Oddi,biliarycineradiography,gallbladder volumemeasurement and ultrastructure observationunder electron microscope were performed.RESULTS In groups Ⅰ and Ⅱ,the basalpressure in low-pressure ampulla or highpressure zone of sphincter of Oddi waselevated,the amplitude of phasic contractionwas decreased and the volume of gallbladderwere increased,with a significant difference(P<0.01)from those of control.Gallstones werefound in group Ⅱ rabbits(7/8).Undercineradiography,low-pressure ampulla showeda spasmodic status without apparent peristalticcontraction.Under electron microscope,insidethe muscular cells of sphincter of Oddi,loosening of microfilament and swelling ofplasmosomes which congregated at the top wereobserved.The amount showed no obviouschange under nitric oxide synthase(NOS)stain.CONCLUSION Twisting of the microfilamentand disarrangement of kink macula densa insidethe muscular ceils suggested that the sphincterof Oddi was under spasmodic status.Theimpaired diastolic function caused andaggravated the stasis of cystic bile.Theswelling plasmosome could be one of theimportant factors in elevating the tonic pressureof sphincter of Oddi. | Wei JG Wang YC Du F Yu HJ | 2000 | World Journal of Gastroenterology2000,6,1: | 19 |

| 6 | Artificial intelligence in breast ultrasound显示文摘Artificial intelligence(AI) is gaining extensive attention for its excellent performance in image-recognition tasks and increasingly applied in breast ultrasound. AI can conduct a quantitative assessment by recognizing imaging information automatically and make more accurate and reproductive imaging diagnosis. Breast cancer is the most commonly diagnosed cancer in women,severely threatening women's health, the early screening of which is closely related to the prognosis of patients. Therefore, utilization of AI in breast cancer screening and detection is of great significance, which can not only save time for radiologists, but also make up for experience and skill deficiency on some beginners. This article illustrates the basic technical knowledge regarding AI in breast ultrasound, including early machine learning algorithms and deep learning algorithms, and their application in the differential diagnosis of benign and malignant masses. At last, we talk about the future perspectives of AI in breast ultrasound. | Ge-Ge Wu Li-Qiang Zhou Jian-Wei Xu Jia-Yu Wang Qi Wei You-Bin Deng Xin-Wu Cui Christoph F Dietrich | 2019 | World Journal of Radiology2019,11,2: | 12 |
| 7 | Structure and receptor-binding properties of an airborne transmissible avian infl uenza A virus hemagglutinin H5(VN1203mut)显示文摘Avian infl uenza A virus continues to pose a global threat with occasional H5N1 human infections,which is em-phasized by a recent severe human infection caused by avian-origin H7N9 in China.Luckily these viruses do not transmit effi ciently in human populations.With a few ami-no acid substitutions of the hemagglutinin H5 protein in the laboratory,two H5 mutants have been shown to obtain an air-borne transmission in a mammalian ferret model.Here in this study one of the mutant H5 proteins devel-oped by Kawaoka’s group(VN1203mut)was expressed in a baculovirus system and its receptor-binding properties were assessed.We herein show that the VN1203mut had a dramatically reduced binding affi nity for the avianα2,3-linkage receptor compared to wild type but showed no detectable increase in affi nity for the humanα2,6-linkage receptor,using Surface Plasmon Resonance techonology.Further,the crystal structures of the VN1203mut and its complexes with either human or avian receptors demon-strate that the VN1203mut binds the human receptor in the same binding manner(cis conformation)as seen for the HAs of previously reported 1957 and 1968 pandemic influenza viruses.Our receptor binding and crystallo-graphic data shown here further confi rm that the ability to bind the avian receptor has to decrease for a higher hu-man receptor binding affi nity.As the Q226L substitution is shown important for obtaining human receptor binding,we suspect that the newly emerged H7N9 binds human receptor as H7 has a Q226L substitution. | Xishan Lu Yi Shi Wei Zhang Yanfang Zhang Jianxun Qi George F Gao | 2013 | Protein & Cell2013,4,7: | 9 |
| 8 | Evaluation of Glycosaminoglycan in the Lumbar Disc Using Chemical Exchange Saturation Transfer MR at 3.0 Tesla:Reproducibility and Correlation with Disc Degeneration显示文摘Objective This study aims to explore the clinical applicability and relevance of glycosaminoglycan Chemical Exchange Saturation Transfer(gag CEST) for intervertebral disc. Methods 25 subjects ranging in age from 24 yrs to 74 yrs were enrolled. gag CEST was acquired using a single-slice TSE sequence on a 3T. Saturation used a continuous rectangular RF pulse with B1=0.8 μT and a fixed duration time =1100 ms. Sagittal image was obtained firstly without saturation pulse, and then saturated images were acquired at 52 offsets ranging from ±0.125 to ±7 parts per million(ppm). MR T2 relaxivity map was acquired at the identical location. Six subjects were scanned twice to assess scan-rescan reproducibility. Results Gag CEST intraclass correlation coefficient(ICC) of six subjects was 0.759 for nucleus pulposus(NP) and 0.508 for annulus fibrosus(AF). Bland-Altman plots showed NP had a mean difference of 0.10%(95% limits of agreement:-3.02% to 3.22%); while that of AF was 0.34%(95% limits of agreement:-2.28% to 2.95%). For the 25 subjects, gag CEST in NP decreased as disc degeneration increased, with a similar trend to T2 relaxivity. Gag CEST of AF showed a better correlation with disc degeneration than T2 relaxivity. Conclusion Gag CEST in NP and AF decreased as disc degeneration increased, while gag CEST in AF showed a better correlation than T2 relaxivity. | Deng Min Yuan Jing Chen Wei Tian Queenie Chan James F Griffith Wang Yi Xiang | 2016 | Biomedical and Environmental Sciences2016,29,1: | 8 |
| 9 | Occurrence of perfluoroalkyl acids in precipitation from Shenyang,China显示文摘Perfluorosulfonates (PFSAs) and perfluorocarboxylates (PFCAs) in precipitation collected from Shenyang, China were determined. Snow samples were collected in the snow event on March 4, 2007 from 34 sites involving both the urban and suburban areas in Shenyang. The snowmelt was preconcentrated by solid phase extraction and analyzed using LC-MS method. Measurable amounts of perfluoroalkyl acids (PFAS) were found in precipitation samples from Shenyang, demonstrating that wet deposition is one possible pathway for the removing of the selected PFAS chemicals from atmosphere. Major PFAS detected were PFOS (<0.38―51 ng/L), PFOA (0.82―13 ng/L) and PFHpA (0.76―11 ng/L), with their mean concentration of 5.4, 3.3 and 2.9 ng/L, respectively. Other PFSAs and PFCAs were detected at much lower frequency or below the limit of detection in all the samples. The work presented here offers some basis for the investigation on the environmental behavior and the evaluation of human exposure to PFAS. | LIU Wei DONG GuangHui JIN YiHe SASAKI Kazuaki SAITO Norimitsu SATO Itaru TSUDA Shuji NAKAYAMA Shoji F | 2009 | Chinese Science Bulletin2009,54,14: | 6 |

| 11 | Interleukin-10 gene polymorphisms and hepatocellular carcinoma susceptibility:A meta-analysis显示文摘AIM: To assess the association between Interleu-kin-10 (IL-10) gene IL-10-1082 (G/A), IL-10-592(C/A), IL-10-819 (T/C) polymorphisms and hepatocellular carcinoma (HCC) susceptibility.METHODS: Two investigators independently searched the Medline, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine Database. Summary odds ratios (ORs) and 95% conf idence intervals (95% CIs) for IL-10 polymorphisms and HCC were cal-culated in a fixed-effects model (the Mantel-Haenszel method) and a random-effects model (the DerSimonian and Laird method) when appropriate. RESULTS: This meta analysis included seven eligiblestudies, which included 1012 HCC cases and 2308 controls. Overall, IL-10-1082 G/A polymorphism was not associated with the risk of HCC (AA vs AG + GG, OR = 1.11, 95% CI = 0.90-1.37). When stratifying for ethnicity, the results were similar (Asian, OR = 1.12, 95% CI = 0.87-1.44; non-Asian, OR = 1.10, 95% CI = 0.75-1.60). In the overall analysis, the IL-10 polymorphism at position -592 (C/A) was identified as a genetic risk factor for HCC among Asians; patients carrying the IL-10-592*C allele had an increased risk of HCC (OR = 1.29, 95% CI = 1.12-1.49). No association was observed between the IL-10-819 T/C polymorphism and HCC susceptibility (TT vs TC + CC, OR = 1.02, 95% CI = 0.79-1.32).CONCLUSION: This meta-analysis suggests that IL-10-592 A/C polymorphism may be associated with HCC among Asians. IL-10-1082 G/A and IL-10-819 T/C polymorphisms were not detected to be related to the risk for HCC. | Yong-Gang Wei, Fei Liu, Bo Li, Xi Chen, Yu Ma, Lv-Nan Yan, Tian-Fu Wen, Ming-Qing Xu, Wen-Tao Wang, Jia-Yin YangYong-Gang Wei, Fei Liu, Bo Li, Xi Chen, Yu Ma, Lv-Nan Yan, Tian-Fu Wen, Ming-Qing Xu, Wen-Tao Wang, Jia-Yin Yang, Department of Liver and Vascular Surgery, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Prov- ince, China Author contributions: Wei YG and Liu F designed the study, collected and analyzed the data and wrote the manuscript Li B collected and analyzed the data and wrote the manuscript Chen X and Ma Y collected and analyzed the data Yan LN analyzed the data and contributed to the discussion Wen TF and Xu MQ revised the manuscript Wang WT and Yang JY contributed to the discussion Wei YG and Liu F contributed equally to this work. | 2011 | World Journal of Gastroenterology2011,17,34: | 3 |

| 15 | Common non-synonymous polymorphisms in the BRCA1 Associated RING Domain (BARD1) gene are associated with breast cancer susceptibility:a case-control analysis显示文摘The BRCA1 Associated RING Domain(BARD1) gene has been identified as a high penetrance gene for breast cancer, whose germline and somatic mutations were reported in both non-BRCA1/2 hereditary site-specific and sporadic breast cancer cases. BARD1 plays a crucial role in tumor repression, along with its heterodimeric partner BRCA1. In the current study, we tested the hypothesis that common non-synonymous polymorphisms in BARD1 are associated with breast cancer susceptibility in a case-control study of 507 patients with incident breast cancer and 539 frequency-matched cancer-free controls in Chinese women. We genotyped all three common(minor allele frequency (MAF) > 0.10) non-synonymous polymorphisms(Pro24Ser, Arg378Ser, and Val507Met) in BARD1. We found that the BARD1 Pro24Ser variant genotypes(24Pro/Ser and 24Ser/Ser) and Arg378Ser variant homozygote 378Ser/Ser were associated with a significantly decreased breast cancer risk, compared with their wild-type homozygotes, respectively. Furthermore, a significant locus-locus interaction was evident between Pro24Ser and Arg378Ser (P-int = 0.032). Among the 378Ser variant allele carriers, the 24Pro/Pro wild-type homozygote was associated with a significantly increased breast cancer risk (adjusted OR = 1.81, 95% CI = 1.11-2.95), but the subjects having 24Pro/Ser or Ser/Ser variant genotypes had a significantly decreased risk(adjusted OR = 0.74, 95% CI = 0.56-0.99). In stratified analysis, this locus-locus interaction was more evident among subjects without family cancer history, those with positive estrogen receptor (ER) and individuals with negative progesterone receptor(PR). These findings indicate that the potentially functional polymorphisms Pro24Ser and Arg378Ser in BARD1 may jointly contribute to the susceptibility of breast cancer. | Huo, X Hu, Z. B Zhai, X.
