| 1 | Minimal invasive microscopic tooth preparation in esthetic restoration: a specialist consensus显示文摘By removing a part of the structure,the tooth preparation provides restorative space,bonding surface,and finish line for various restorations on abutment.Preparation technique plays critical role in achieving the optimal result of tooth preparation.With successful application of microscope in endodontics for>30 years,there is a full expectation of microscopic dentistry.However,as relatively little progress has been made in the application of microscopic dentistry in prosthodontics,the following assumptions have been proposed:Is it suitable to choose the tooth preparation technique under the naked eye in the microscopic vision?Is there a more accurate preparation technology intended for the microscope?To obtain long-term stable therapeutic effects,is it much easier to achieve maximum tooth preservation and retinal protection and maintain periodontal tissue and oral function health under microscopic vision?Whether the microscopic prosthodontics is a gimmick or a breakthrough in obtaining an ideal tooth preparation should be resolved in microscopic tooth preparation.This article attempts to illustrate the concept,core elements,and indications of microscopic minimally invasive tooth preparation,physiological basis of dental pulp,periodontium and functions involved in tool preparation,position ergonomics and visual basis for dentists,comparison of tooth preparation by naked eyes and a microscope,and comparison of different designs of microscopic minimally invasive tooth preparation techniques.Furthermore,a clinical protocol for microscopic minimally invasive tooth preparation based on target restorative space guide plate has been put forward and new insights on the quantity and shape of microscopic minimally invasive tooth preparation has been provided. | Haiyang Yu Yuwei Zhao Junying Li Tian Luo Jing Gao Hongchen Liu Weicai Liu Feng Liu Ke Zhao Fei Liu Chufan Ma Juergen MSetz Shanshan Liang Lin Fan Shanshan Gao Zhuoli Zhu Jiefei Shen Jian Wang Zhimin Zhu Xuedong Zhou | 2019 | International Journal of Oral Science2019，11，4： | 25 |
| 2 | Healthy function and high valued utilization of edible fungi显示文摘Edible fungi are large fungi with high added value that can be utilized as resources.They are rich in high-quality protein,carbohydrate,various vitamins,mineral elements and other nutrients,and are characterized by high protein,low sugar,low fat and low cholesterol.In addition,edible fungi contain a variety of bioactive substances,such as polysaccharides,dietary fiber,steroids,polyphenols,and most of these compounds have antioxidant,anti-tumor and other physiological functions.This review comprehensively discusses the bioactive components and functional characteristics of edible fungi(such as antioxidant,anti-aging,hypolipidemic activities,etc.).Then the recent developments and prospect in the high-valued utilization of edible fungi are discussed and summarized.The objective of this review is to improve the understanding of health-promoting properties of edible fungi,and provide reference for the industrial production of edible fungi-based health products. | Yanrong Zhang Dawei Wang Yuetong Chen Tingting Liu Shanshan Zhang Hongxiu Fan Hongcheng Liu Yu Li | 2021 | Food Science and Human Wellness2021，10，4： | 20 |
| 3 | Polysaccharides from Angelica sinensis alleviate neuronal cell injury caused by oxidative stress显示文摘Angelica sinensis has antioxidative and neuroprotective effects. In the present study, we aimed to determine the neuroprotective effect of polysaccharides isolated from Angelica sinensis. In a preliminary experiment, Angelica sinensis polysaccharides not only protected PC12 neuronal cells from H 2 O 2-induced cytotoxicity, but also reduced apoptosis and intracellular reactive oxygen species levels, and increased the mitochondrial membrane potential induced by H 2 O 2 treatment. In a rat model of local cerebral ischemia, we further demonstrated that Angelica sinensis polysaccharides enhanced the antioxidant activity in cerebral cortical neurons, increased the number of microvessels, and improved blood flow after ischemia. Our findings highlight the protective role of polysaccharides isolated from Angelica sinensis against nerve cell injury and impairment caused by oxidative stress. | Tao Lei Haifeng Li Zhen Fang Junbin Lin Shanshan Wang Lingyun Xiao Fan Yang Xin Liu Junjian Zhang Zebo Huang Weijing Liao | 2014 | Neural Regeneration Research2014，9，3： | 17 |
| 4 | Evaluation of contrast-enhanced ultrasound for diagnosis of dysplastic nodules with a focus of hepatocellular carcinoma in liver cirrhosis patients显示文摘Objective: To compare the enhancement features of dysplastic nodules with a focus of hepatocellular carcinoma(DN-HCC) versus HCC and regenerative nodules(RN) in cirrhotic patients.Methods: One hundred and ninety-three cirrhotic patients were enrolled in this study; they had 215 focal liver lesions, 1.0-3.5 cm in size, which were examined using contrast-enhanced ultrasound(CEUS) with Sono Vue?and diagnosed as HCC, RN or DN-HCC by biopsy. Samples were obtained using 18-gauge needles in the different enhanced areas. The enhancement features of DN-HCC, HCC and RN were evaluated.Results: There were 86 HCC lesions, 102 RN lesions, and 27 DN-HCC lesions diagnosed by biopsy. Of 86 HCC lesions, 87.2%(75/86) showed complete enhancement during the arterial phase, and 12.8%(11/86) had inhomogeneous enhancement, with no enhancement in the central area during the arterial phase; 100%(86/86) exhibited washout during the late phase. Of 102 RN lesions, 95.1%(97/102) had delayed or simultaneous enhancement during the arterial phase, and 4.9%(5/102) displayed slight enhancement during the arterial phase; 26.5%(27/102) exhibited washout and 73.5%(75/102) exhibited no washout during the late phase. In 27 DN-HCC lesions, only part of the lesions enhanced during the arterial phase and washed out during the late phase; the other areas had delayed or simultaneous enhancement during the arterial phase, and 29.6%(8/27) exhibited slight washout in the late phase. In 86 HCCs, the pathological feature was HCC in the enhanced area of 75 lesions, hepatocellular fatty degeneration in the slightly enhanced area of 7 lesions, and hepatocellular necrosis in the unenhanced area and HCC in the enhanced area of 4 lesions. In 102 RNs, the pathological diagnosis was hepatocyte proliferation with or without fatty degeneration. In 27 DN-HCCs, the pathological feature was HCC in the enhanced area and hepatocyte regeneration in the unenhanced area.Conclusions: CEUS is useful for the diagnosis of focal liver lesions in cirrhotic patients. CEUS can help determine the progression from RN to DN-HCC to HCC by analyzing the hemodynamics. CEUS can promote the diagnostic accuracy of a biopsy by providing more accurate information on the site of the biopsy. | Wei Wu Minhua Chen Kun Yan Yin Dai Shanshan Yin Wei Yang Zhihui Fan | 2015 | Chinese Journal of Cancer Research2015，27，1： | 15 |
| 5 | The prognostic and therapeutic implications of circulating tumor cell phenotype detection based on epithelial-mesenchymal transition markers in the first-line chemotherapy of HER2-negative metastatic breast cancer显示文摘Background:Epithelial-mesenchymal transition(EMT)is implicated in the metastatic process and presents a chal-lenge to epithelial cell adhesion molecule-based detection of circulating tumor cells(CTCs),which have been demon-strated to be a prognostic indicator in metastatic breast cancer.Although evidence has indicated that heterogeneity of CTCs based on EMT markers is associated with disease progression,no standard recommendations have been established for clinical practice.This study aimed to evaluate the prognostic significance of dynamic CTC detection based on EMT for metastatic breast cancer patients.Methods:We enrolled 108 human epidermal growth factor receptor 2-negative metastatic breast cancer patients from the prospective phase III CAMELLIA study and applied the CanPatrol CTC enrichment technique to identify CTC phenotypes(including epithelial CTCs,biphenotypic epithelial/mesenchymal CTCs,and mesenchymal CTCs)in peripheral blood samples.Receiver operating characteristic curve analyses of total CTC count and the proportion of mesenchymal CTCs for predicting the 1-year progression-free survival(PFS)rate were conducted to determine the optimal cut-off values,and Kaplan-Meier analysis and Cox proportional hazards regression analysis were performed to investigate the prognostic value of the cut-off values of both total CTC count and the proportion of mesenchymal CTCs in combination.Results:For predicting the 1-year PFS rate,the optimal cut-off value of total CTC count was 9.5(Area under the curve[AUC]=0.538,95%confidence interval[CI]=0.418-0.657),and that of the proportion of mesenchymal CTCs was 10.7%(AUC=0.581,95%CI=0.463-0.699).We used the two cut-off values in combination to forecast PFS in which the total CTC count was equaled to or exceeded 10/5 mL with the proportion of mesenchymal CTCs surpassed 10.7%.Patients who met the combined criteria had significantly shorter median PFS than did those who did not meet the criteria(6.2 vs.9.9 months,P=0.010).A nomogram was constructed based on the criteria and significant clinicopatho-logical characteristics with a C-index of 0.613(P=0.010).Conclusions: The criteria, which combine the total CTC count and the proportion of mesenchymal CTCs, may be used to monitor therapeutic resistance and predict prognosis in patients with metastatic breast cancer. | Xiuwen Guan Fei Ma Chunxiao Li Shiyang Wu Shangying Hu Jiefen Huang Xiaoying Sun Jiayu Wang Yang Luo Ruigang Cai Ying Fan Qiao Li Shanshan Chen Pin Zhang Qing Li Binghe Xu | 2019 | Cancer Communications2019，39，1： | 15 |
| 6 | A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice. | Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan | 2019 | Cell Research2019，29，10： | 13 |
| 7 | Single-cell transcriptomic atlas of primate cardiopulmonary aging显示文摘Aging is a major risk factor for many diseases,especially in highly prevalent cardiopulmonary comorbidities and infectious diseases including Coronavirus Disease 2019(COVID-19).Resolving cellular and molecular mechanisms associated with aging in higher mammals is therefore urgently needed.Here,we created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung,heart and artery,the top tissues targeted by SARS-CoV-2.Analysis of cell type-specific aging-associated transcriptional changes revealed increased systemic inflammation and compromised virus defense as a hallmark of cardiopulmonary aging.With age,expression of the SARS-CoV-2 receptor angiotensin-converting enzyme 2(ACE2)was increased in the pulmonary alveolar epithelial barrier,cardiomyocytes,and vascular endothelial cells.We found that interleukin 7(IL7)accumulated in aged cardiopulmonary tissues and induced ACE2 expression in human vascular endothelial cells in an NF-κB-dependent manner.Furthermore,treatment with vitamin C blocked IL7-induced ACE2 expression.Altogether,our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2,suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly. | Shuai Ma Shuhui Sun Jiaming Li Yanling Fan Jing Qu Liang Sun Si Wang Yiyuan Zhang Shanshan Yang Zunpeng Liu Zeming Wu Sheng Zhang Qiaoran Wang Aihua Zheng Shuguang Duo Yang Yu Juan Carlos Izpisua Belmonte Piu Chan Qi Zhou Moshi Song Weiqi Zhang Guang-Hui Liu | 2021 | Cell Research2021，31，4： | 10 |
| 8 | Isolation,purification,structural characteristic and antioxidative property of polysaccharides from A.cepa L.var.agrogatum Don显示文摘Allium cepa L.var.agrogatum Don(ALAP)is commonly consumed in China as well as other regions and has various beneficial health effects.A novel acidic polysaccharide(named ALAP-21)was obtained from ALAP by ultrasonic and microwave-assisted extraction and purification using DEAE-52 anion exchange and Sephadex G-100 columns.The monosaccharide composition,structural and antioxidative properties of ALAP-21 were investigated by GC–MS chromatography,FT-IR and NMR spectroscopies and three antioxidative activity tests in vitro.The results showed that ALAP-21 was a heteropolysaccharide composed of glucose,galacturonic acid,mannose,galactose,arabinose,rhamnose,xylose,fructose and glucuronic acid with a relative molar ratio of 26.282:27.546:11.400:4.781:2.467:2.445:3.622:1.106:1.753,owning(1→4)-β-d-Glcp,(1→4)-β-d-GalAp6Me3OA,(1→4)-β-d-Galp6OMe,(1→2)-β-l-Rhap,(1→4)-β-d-Manp glycosidic linkages.(1→4)-β-d-Glcp and(1→4)-β-d-GalAp6Me3OA residues might be the main components of the sugar chain backbone of ALAP-21.Furthermore,ALAP-21 exhibited high potential for DPPH radicals(82.02%),hydroxyl radicals(53.33%)and superoxide anion radicals(50.28%).These results provide a reference for further research and rational development of ALAP polysaccharides. | Hongcheng Liu Hongxiu Fan Jing Zhang Shanshan Zhang Wenting Zhao Tingting Liu Dawei Wang | 2020 | Food Science and Human Wellness2020，9，1： | 10 |
| 9 | Occurrence of mycotoxins in feed ingredients and complete feeds obtained from the Beijing region of China显示文摘Background:The current study was carried out to provide a reference for the control of mycotoxin contamination in feed ingredients and complete feeds for swine.Methods:A total of 55 feed ingredients,including 14 corn,13 wheat bran,11 soybean meal and 17 dried distillers grains with solubles(DDGS) as well as 76 complete swine feeds including 7 creep feeds,14 starter feeds,14 grower feeds,18 grower-finisher feeds,10 gestating sow feeds,and 13 lactating sow feeds were randomly collected from15 swine farms located in the Beijing region of China from July to August 2011.Immunoaffinity clean-up,using High-Performance Liquid Chromatography(HPLC) in combination with UV or Fluorescence Detection,was used for quantitative analysis of aflatoxin B,(AFB,),deoxynivalenol(DON),zearalenone(ZEA) and ochratoxin A(OTA) in the ingredients and complete feeds.Results:DON and ZEA were the most prevalent mycotoxins found.DON was detected at percentages of 93,92,54,100 and 97%with a mean level of 1.01,0.44,0.05,1.36 and 0.65 ppm in the samples of corn,wheat bran,soybean meal,DDGS and complete feeds,respectively.The detected percentages of ZEA were 100,100,54,100 and 100 with mean levels of 109.1,14.9,9.2,882.7 and 58.9 ppb in the same samples.In the wheat bran and soybean meal samples,the content of all four mycotoxins were below the maximum limits set by Chinese regulations while the percentage of samples that exceeded regulatory limits were 7,57 and 7%for corn,and 7,14 and 3%for the complete feeds for AFB,,DON and OTA respectively.DDGS showed the most serious mycotoxin contamination and the percentage of samples that exceeded regulatory limits were 6,88 and 41%,for AFB,,DON and ZEA,respectively.Conclusions:This paper is the first to present data on the natural occurrence of AFB,,DON,ZEA and OTA in ingredients and complete feeds obtained from swine farms in China's Beijing region.The data shows that feed ingredients and complete swine feeds obtained from these farms are most often contaminated with DON followed by contamination with AFB,and ZEA. | Xiaoying Li Lihong Zhao Yu Fan Yaxiong Jia Lei Sun Shanshan Ma Cheng Ji Qiugang Ma Jianyun Zhang | 2014 | Journal of Animal Science and Biotechnology2014，5，4： | 7 |
| 10 | Effects of surfactants on graphene oxide nanoparticles transport in saturated porous media显示文摘Transport behaviors of graphene oxide nanoparticles(GONPs) in saturated porous media were examined as a function of the presence and concentration of anionic surfactant(SDBS)and non-ionic surfactant(Triton X-100) under different ionic strength(IS). The results showed that the GONPs were retained obviously in the sand columns at both IS of 50 and200 mmol/L, and they were more mobile at lower IS. The presence and concentration of surfactants could enhance the GONP transport, particularly as observed at higher IS. It was interesting to see that the GONP transport was surfactant type dependent, and SDBS was more effective to facilitate GONP transport than Triton X-100 in our experimental conditions. The advection–dispersion–retention numerical modeling followed this trend and depicted the difference quantitatively. Derjaguin–Landau–Verwey–Overbeek(DLVO)interaction calculations also were performed to interpret these effects, indicating that secondary minimum deposition was critical in this study. | Wei Fan Xuehui Jiang Ying Lu Mingxin Huo Shanshan Lin Zhi Geng | 2015 | Journal of Environmental Sciences2015，27，9： | 6 |
| 11 | Bathymetric Prediction from Multi-source Satellite Altimetry Gravity Data显示文摘According to the 'theoretical admittance ' and the 'observation admittance' of the actual data,the theoretical value of effective elastic thickness in the study area was 10 km.Combining the gravity anomalies and vertical gravity gradient anomalies,the admittance function is used to construct the 1′×1′ bathymetry model over the Philippine Sea by using the adaptive weighting technique.It is found that the accuracy of the bathymetry model constructed is the highest when the ratio of inversion result of vertical gravity gradient anomalies and inversion result of gravity anomalies is 2∶3.At the same time,using multi-source gravity data to predict bathymetry could synthesize the superiority of gravity anomalies and vertical gravity gradient anomalies on the different seafloor topography,and the accuracy is better than bathymetry model that only used gravity anomalies or vertical gravity gradient anomalies.Taking the ship test data as the checking condition,the accuracy of predicting model is slightly lower than that of V18.1 model and improved by 27.17% and 39.02% respectively compared with the ETOPO1 model and the DTU10 model.Check points which the absolute value of the relative error of the predicting model is in the range of 5% accounted for 94.25% of the total. | Diao FAN Shanshan LI Shuyu MENG Chi ZHANG Jinkai FENG Yan HUANG Jiawei DU Zhibin XING | 2019 | Journal of Geodesy and Geoinformation Science2019，2，1： | 6 |

| 13 | Joint Occurrence Period of Wind Speed and Wave Height Based on Both Service Term and Risk Probability显示文摘Return periods calculated for different environmental conditions are key parameters for ocean platform design.Many codes for offshore structure design give no consideration about the correlativity among multi-loads and over-estimate design values.This frequently leads to not only higher investment but also distortion of structural reliability analysis.The definition of design return period in existing codes and industry criteria in China are summarized.Then joint return periods of different ocean environmental parameters are determined from the view of service term and danger risk.Based on a bivariate equivalent maximum entropy distribution,joint design parameters are estimated for the concomitant wave height and wind speed at a site in the Bohai Sea.The calculated results show that even if the return period of each environmental factor,such as wave height or wind speed,is small,their combinations can lead to larger joint return periods.Proper design criteria for joint return period associated with concomitant environmental conditions will reduce structural size and lead to lower investment of ocean platforms for the exploitation of marginal oil field. | DONG Sheng FAN Dunqiu TAO Shanshan | 2012 | Journal of Ocean University of China2012，11，4： | 5 |

| 15 | Impervious surface extraction based on different methods from multiple spatial resolution images:a comprehensive comparison显示文摘Many efforts have been devoted to extracting impervious surfaces based on different methods from multiple spatial resolution images.Differences in extraction methods and spatial resolutions are significant and have led to discrepant performances in terms of the impervious surface extraction accuracy.However,which extraction method is more suitable for which kind of spatial resolution image in practice is poorly understood.This study systematically compared the performances of 12 methods of impervious surface extraction for four spatial resolution images(i.e.Landsat 8[30 m],Sentinel-2A[20 m],Sentinel-2A[10 m],and Gaofen-2[4 m])in three testing areas.The results indicated that for the mediumspatial resolutions of 30 and 20 m,the support vector machine(SVM)method was considered as the optimal classification method with the highest accuracy of impervious surface extraction.For the high-spatial resolutions of 10 and 4 m,the object based image analysis(OBIA)method obtained the highest accuracy of the impervious surface distribution.Furthermore,the perpendicular impervious surface index(PISI)outperformed the other indices in obtaining the impervious surface distribution,with the highest accuracy for four spatial resolution images.These comprehensive assessments can provide a valuable guidance for future impervious surface extraction from different spatial resolutions. | Shanshan Feng Fenglei Fan | 2021 | International Journal of Digital Earth2021，14，9： | 4 |
| 16 | Fluxing Agents on Ceramification of Composites of MgO-Al2O3-SiO2/Boron Phenolic Resin显示文摘Fluxing agents of zinc borate, antimony oxide, galss frit A and glass frit B, with different melting or softening point temperatures, were added into MgO-Al_2O_3-SiO_2/boron phenol formaldehyde resin(MAS/BPF) composites to lower the formation temperature of eutectic liquid phase and promote the ceramification of ceramifiable composites. The effects of fluxing agents on the thermogravimetric properties, phase evolution, and microstructure evolution of MAS/BPF composites were characterized by TG-DSC, XRD and SEM analyses. The results reveal that the addition of a fluxing agent highly reduces the decomposition rate of MAS/BPF composites. Fluxing agents lower the formation temperatures of liquid phases of ceramifiable MAS/BPF composites obviously, and then promote the ceramification and densification process. The final residues of composites are ceramic surrounded by large amount of glass phases. | 石敏先 CHEN Xia FAN Shanshan SHEN Shirley LIU Tianxiang 黄志雄 | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，2： | 4 |
| 17 | Emerging role of metabolic reprogramming in tumor immune evasion and immunotherapy显示文摘Mounting evidence has revealed that the therapeutic efficacy of immunotherapies is restricted to a small portion of cancer patients.A deeper understanding of how metabolic reprogramming in the tumor microenvironment(TME)regulates immunity remains a major challenge to tumor eradication.It has been suggested that metabolic reprogramming in the TME may affect metabolism in immune cells and subsequently suppress immune function.Tumor cells compete with infiltrating immune cells for nutrients and metabolites.Notably,the immunosuppressive TME is characterized by catabolic and anabolic processes that are critical for immune cell function,and elevated inhibitory signals may favor cancer immune evasion.The major energy sources that supply different immune cell subtypes also undergo reprogramming.We herein summarize the metabolic remodeling in tumor cells and different immune cell subtypes and the latest advances underlying the use of metabolic checkpoints in antitumor immunotherapies.In this context,targeting both tumor and immune cell metabolic reprogramming may enhance therapeutic efficacy. | Chunmei Fan Shanshan Zhang Zhaojian Gong Xiayu Li Bo Xiang Hao Deng Ming Zhou Guiyuan Li Yong Li Wei Xiong Zhaoyang Zeng Xiaoling Li | 2021 | Science China(Life Sciences)2021，64，4： | 4 |
| 18 | Dynamic cell transition and immune response landscapes of axolotl limb regeneration revealed by single-cell analysis显示文摘Dear Editor,The axolotl,Ambystoma mexicanum,has extraordinary capability to fully recover multiple tissues after lost,whereas such capability has disappeared in mammals.Thus,deci-phering detailed mechanisms underlying axolotl regenera-tion could provide valuable lessons for regenerative medicine.However,many questions,such as the origin of essential progenitor cells and key responses of individual types of cells for regeneration remain elusive(Haas and Whited,2017).Newly developed single-cell RNA sequenc-ing(scRNA-seq)method enables researchers to observe cellular and molecular dynamics in axolotl regeneration at the single-cell resolution(Gerber et al.,2018;Leigh et al.,2018),but the reported transcriptome landscapes are only for certain cell types or in certain regenerative stages.A complete overview of the regeneration process for all cell types is still lacking. | Hanbo Li Xiaoyu Wei Li Zhou Weiqi Zhang Chen Wang Yang Guo Denghui Li Jjianyang Chen Tianbin Liu Yingying Zhang Shuai Ma Congyan Wang Fujian Tan Jiangshan Xu Yang Liu Yue Yuan Liang Chen Qiaoran Wang Jing Qu Yue Shen Shanshan Liu Guangyi Fan Longqi Liu Xin Liu Yong Hou Guang-Hui Liu Ying Gu Xun Xu | 2021 | Protein & Cell2021，12，1： | 3 |

| 20 | Polymorphisms of MTHFR and TYMS predict capecitabine-induced hand-foot syndrome in patients with metastatic breast cancer显示文摘Background:Breast cancer is a global problem,and a large number of new cases are diagnosed every year.Capecit-abine is effective in patients with metastatic breast cancer(MBC).Hand-foot syndrome(HFS)is a common adverse effect of capecitabine.In this study,we investigated the association between single nucleotide polymorphisms(SNPs)in genes involved in capecitabine metabolism pathways and capecitabine-induced HFS in Chinese patients with MBC to identify some predictive genetic biomarkers.Methods:We selected 3 genes involved in capecitabine metabolism and screened genetic variants in these target genes.We genotyped a total of 22 SNPs in the thymidylate synthase gene(TYMS),the methylene tetrahydrofolate reductase gene(MTHFR),and the ribonucleotide reductase M1 gene(RRM1)in 342 MBC patients treated with capecit-abine-based chemotherapy.The genotype distributions of each SNP in patients with and without HFS were assessed using Pearson’sχ^(2)test,and the relationship between HFS and genotypes of SNPs was determined using logistic regression analysis.The association between SNPs and their corresponding gene expression was analyzed using the Blood expression quantitative trait loci(eQTL)browser online tools.Results:We found 4 positive sites for HFS in the TYMS and MTHFR genes:TYMS rs2606241(P=0.022),TYMS rs2853741(P=0.019),MTHFR rs3737964(P=0.029),and MTHFR rs4846048(P=0.030).Logistic regression analyses showed that the genotype AG of MTHFR rs3737964[odds ratio(OR)=0.54,95%confidence interval(CI)0.31-0.97,P=0.038]and MTHFR rs4846048(OR=0.54,95%CI 0.30-0.98,P=0.042)were protective factors of HFS,whereas the genotype CT of TYMS rs2853741(OR=2.25,95%CI 1.31-3.87,P=0.012)increased the risk of HFS.The association between the genotype GT of TYMS rs2606241(OR=1.27,95%CI 0.73-2.23,P=0.012)and HFS was uncertain.Further eQTL analyses confirmed that the alleles of rs3737964 and rs4846048 affected the gene expression levels of MTHFR in cis.Conclusions:We have identified four potentially useful pharmacogenetic markers,TYMS rs2606241,TYMS rs2853741,MTHFR rs3737964,and MTHFR rs4846048 to predict capecitabine-induced HFS in MBC patients. | Shaoyan Lin Jian Yue Xiuwen Guan Peng Yuan Jiayu Wang Yang Luo Ying Fan Ruigang Cai Qiao Li Shanshan Chen Pin Zhang Qing Li Fei Ma Binghe Xu | 2019 | Cancer Communications2019，39，1： | 3 |
