| 1 | 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 |
| 2 | Trastuzumab plus adjuvant chemotherapy for human epidermal growth factor receptor 2(HER2)-positive early-stage breast cancer: A real-world retrospective study in Chinese patients显示文摘Objective: To assess the long-term effectiveness and safety of trastuzumab in adjuvant therapy for Chinese patients with early-stage human epidermal growth factor 2(HER2)-positive breast cancer in a real-world setting.Methods: This retrospective observational study analyzed the medical records of HER2-positive breast cancer patients between 2000 and 2012 at the Chinese Academy of Medical Sciences. Patients who received adjuvant chemotherapy alone or adjuvant chemotherapy followed by/combined with trastuzumab were included. The Kaplan-Meier method was used to estimate disease-free survival(DFS) and overall survival(OS). Hazard ratios(HR) and 95% confidence intervals(95% CI) were calculated using the Cox regression model.Results: Of the 1,348 patients analyzed, 909 received chemotherapy alone and 439 received chemotherapy plus trastuzumab. The 3-year, 5-year and 10-year DFS rates were 83.70%, 76.38% and 68.94%, respectively, in the chemotherapy-alone cohort, and 90.21%, 86.19% and 83.45% in the chemotherapy plus trastuzumab cohort. The3-year, 5-year and 10-year OS rates were 96.10%, 91.40% and 81.88% in the chemotherapy-alone cohort, and98.17%, 94.91% and 90.01% in the chemotherapy plus trastuzumab cohort. The chemotherapy plus trastuzumab group had a significantly lower risk of disease recurrence and death than the chemotherapy-alone group(DFS:HR=0.50, 95% CI, 0.37-0.68;P<0.001;OS: HR=0.53, 95% CI, 0.34-0.81;P=0.004) after adjusting for covariates.In the 439 patients treated with trastuzumab, multivariate analysis suggested that lymph node positivity, higher T stages, and hormone receptor-negative status were significantly associated with higher risks of disease recurrence,and lymph node positivity and hormone receptor-negative status were significantly associated with higher risks of death. Grade 3/4 adverse events(incidence ≥1%) were more common in patients receiving trastuzumab(54.44% vs.15.73%).Conclusions: Early-stage HER2-positive breast cancer patients treated with trastuzumab plus adjuvant chemotherapy have a significant survival benefit compared with chemotherapy-alone in real-world settings. Lymph node positivity, hormone receptor-negative status, and higher T stages may be associated with higher risks of recurrence, and effective therapy for patients with these factors is required. | Jihong Guo Qing Li Pin Zhang Peng Yuan Jiayu Wang Fei Ma Ying Fan Ruigang Cai Yang Luo Qiao Li Binghe Xu | 2019 | Chinese Journal of Cancer Research2019，31，5： | 6 |
| 3 | Challenges and strategies in high-accuracy manufacturing of the world’s largest SiC aspheric mirror显示文摘In the process of manufacturing the world’s largest silicon carbide(SiC)aspheric mirror,the primary difficulties are mirror blank preparation,asphere fabrication,and testing,as well as cladding and coating.Specifically,the challenges include the homogeneity of the complicated structure casting,accuracy and efficiency of the fabrication process,print-through effect,fidelity and precision of test procedure,stress and denseness of cladding process,the dynamic range of interferometric measurement,and air turbulence error due to the long optical path.To break through such a barrier of difficulties,we proposed the water-soluble room temperature vanishing mold and gel casting technology,homogeneous microstructure reaction-formed joint technology,nano-accuracy efficient compound fabrication,gravity unloading technology,high-denseness low-defect physical vapor deposition(PVD)Si-cladding technology,test data fusion method,and time-domain averaging method,etc.Based on the proposed technologies and methods,we have accomplished the world’s largest SiC aspheric mirror with a size of φ4.03 m.The impressive performance of the SiC aspheric mirror is validated by the characteristics of the fabricated SiC aspheric mirror.The aerial density of the SiC blank is less than 120 kg/m^(2),surface shape test accuracy is better than 6 nm RMS,thickness inhomogeneity of the cladding layer is less than 5%,and the final surface figure error and roughness are 15.2 nm RMS and 0.8 nm RMS,respectively. | Xuejun Zhang Haixiang Hu Xiaokun Wang Xiao Luo Ge Zhang Wenxing Zhao Xiaoyi Wang Zhenyu Liu Ling Xiong Erhui Qi Congcong Cui Yanchao Wang Yingjie Li Xu Wang Longxiang Li Yang Bai Qiang Cheng Zhiyu Zhang Ruigang Li Wa Tang Xuefeng Zeng Weijie Deng Feng Zhang | 2022 | Light(Science & Applications)2022，11，12： | 3 |
| 4 | 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 |
| 5 | Genetic polymorphisms of autophagy-related gene 5 (ATG5) rs473543 predict different disease-free survivals of triple-negative breast cancer patients receiving anthracycline- and/or taxane-based adjuvant chemotherapy显示文摘Background:Autophagy plays a crucial role in chemotherapy resistance of triple-negative breast cancer(TNBC).Hence,autophagy-related gene 5(ATG5),an essential molecule involved in autophagy regulation,is presumably associated with recurrence of TNBC.This study was aimed to investigate the potential influence of single-nucleotide polymorphisms in ATG5 on the disease-free survival(DFS)of early-stage TNBC patients treated with anthracycline-and/or taxane-based chemotherapy.Methods:We genotyped ATG5 SNP rs473543 in a cohort of 316 TNBC patients treated with anthracycline-and/or taxane-based chemotherapy using the sequenom’s MassARRAY system.Kaplan-Meier survival analysis and Cox proportional hazard regression analysis were used to analyze the association between ATG5 rs473543 genotypes and the clinical outcome of TNBC patients.Results:Three genotypes,AA,GA,and GG,were detected in the rs473543 of ATG5 gene.The distribution of ATG5 rs473543 genotypes was significantly different between patients with and without recurrence(P=0.024).Kaplan-Meier survival analysis showed that patients carrying A allele of ATG5 rs473543 had an increased risk of recurrence and shorter DFS compared with those carrying the variant genotype GG in rs473543(P=0.034).In addition,after adjust-ing for clinical factors,multivariate Cox regression analyses revealed that the AA/GA genotype of rs473543 was an independent predictor for DFS(hazard risk[HR],1.73;95%confidence interval[CI],1.04-2.87;P=0.034).In addition,DFS was shorter in node-negative patients with the presence of A allele(AA/GA)than in those with the absence of A allele(P=0.027).Conclusion:ATG5 rs473543 genotypes may serve as a potential marker for predicting recurrence of early-stage TNBC patients who received anthracycline-and/or taxane-based regimens as adjuvant chemotherapy. | Meiying Li Fei Ma Jiayu Wang Qing Li Pin Zhang Peng Yuan Yang Luo Ruigang Cai Ying Fan Shanshan Chen Qiao Li Binghe Xu | 2018 | Cancer Communications2018，38，1： | 2 |

| 13 | MTHFR和TYMS的多态性预测转移性乳腺癌患者因卡培他滨诱发的手足综合征显示文摘背景与目的乳腺癌是一个全球性问题,每年都会诊断出大量的新发病例。卡培他滨对转移性乳腺癌(metastatic breast cancer,MBC)患者有效。手足综合征(hand-foot syndrome,HFS)是卡培他滨的常见不良反应。在本文中,我们研究了卡培他滨代谢通路相关基因中的单核苷酸多态性(single nucleotide polymorphisms,SNPs)与卡培他滨诱导的中国MBC患者HFS之间的相关性,以确定一些具有预测性的生物标志物基因。方法我们选择了3个参与卡培他滨代谢的基因,并筛选了这些靶基因的遗传变体。我们对342例接受卡培他滨化疗的MBC患者的胸苷酸合酶基因(thymidylate synthase gene,TYMS)、亚甲基四氢叶酸还原酶基因(methylene tetrahydrofolate reductase gene,MTHFR)和核糖核苷酸还原酶M1基因(ribonucleotide reductaseM1gene,RRM1)中的22个SNPs进行了基因分型。使用Pearson’sχ2检验评估患有和不患有HFS的患者中每个SNP的基因型分布,并使用logistic回归分析确定HFS与SNP的基因型之间的相关性。使用血液表达数量定量性状基因座(expression quantitative trait loci,e QTL)Browser在线工具分析了SNP及其对应基因表达之间的相关性。结果我们在TYMS和MTHFR基因中发现了4个HFS阳性位点:TYMS rs2606241(P=0.022)、TYMS rs2853741(P=0.019)、MTHFR rs3737964(P=0.029)和MTHFR rs4846048(P=0.030)。Logistic回归分析显示,MTHFR rs3737964[比值比(odds ratio,OR)=0.54,95%置信区间(confidence interval,CI):0.3–0.97,P=0.038]和MTHFRrs4846048(OR=0.54,95%CI:0.30–0.98,P=0.042)的基因型AG是HFS的保护因素,而TYMS rs2853741的基因型CT(OR=2.25,95%CI:1.31–3.87,P=0.012)增加了HFS的风险。TYMSrs2606241的基因型GT(OR=1.27,95%CI:0.73–2.23,P=0.012)与HFS之间的相关性尚不确定。进一步的e QTL分析证实,rs3737964和rs4846048的等位基因影响顺式MTHFR的基因表达水平。结论我们已经确定了4个潜在有效的药物遗传学标记,TYMS rs2606241、TYMS rs2853741、MTHFR rs3737964和MTHFR rs4846048可以预测卡培他滨诱导的MBC患者的HFS。 | 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 | 癌症2019，38，11： | 1 |
| 14 | Treatment patterns and clinical outcomes in patients with metastatic breast cancer treated with palbociclib-based therapies:real-world data in the Han population显示文摘Background:This study aimed to reveal the treatment patterns and clinical outcomes of diverse palbociclib-based regimens in Han patients with estrogen receptor-positive(ER+)metastatic breast cancer in routine clinical practice.Methods:The clinical data of patients with ER+metastatic breast cancer treated with palbociclib were collected from the National Cancer Center database.The efficacy profile of palbociclib in this Han population was evaluated,especially for various combination regimens.The efficacy of palbociclib-based therapy in patients with prior everolimus treatment was also assessed.Results:A total of 186 patients from 89 cities in 18 provinces in China were enrolled.The median progression-free survival(PFS)was similar among different palbociclib-combined groups(P=0.566):10.0 months(95%confidence interval[CI]3.8-16.1)in the+exemestane group,9.7 months(95%CI 6.3-13.1)in the+letrozole group,7.8 months(95%CI 5.5-10.2)in the+fulvestrant group,7.2 months(95%CI 3.2-11.3)in the+toremifene group,and 6.1 months(95%CI 1.2-11.0)in the+anastrozole group.Thirty-four patients(18.3%)had received everolimus for their metastatic disease before the prescription of palbociclib.The disease control rate was significantly lower in patients who had received previous everolimus than in the everolimus-naïve group(50.0%vs.82.2%,P<0.001).Patients pre-treated with everolimus had significantly worse PFS than those in the everolimus-naïve group(3.4 months vs.8.8 months,P=0.001).After propensity score matching,patients pre-treated with everolimus had similar PFS(4.4 months,95%CI 0.5-8.2)compared with everolimus-naïve patients(6.1 months,95%CI 4.7-7.5,P=0.439).Conclusions:Various palbociclib-based regimens have promising efficacy in ER+metastatic breast cancer in real-world settings,even in patients who had been pre-treated with everolimus. | Hongnan Mo Fei Ma Qing Li Pin Zhang Peng Yuan Jiayu Wang Yang Luo Ruigang Cai Qiao Li Binghe Xu | 2022 | Chinese Medical Journal2022，，14： | 0 |
| 15 | Study on Fly Ash Based Porous Ceramsite as Biological Filter Media显示文摘Using fly ash as a raw material,porous ceramic particles with an apparent density of 1.21 g/cm^(3),a visible porosity of 51.03%,and a specific surface area of 4.26 m^(2)/g were prepared and used as biofilter materials for wastewater treatment.Through SEM,XRD analysis,and heavy metal leaching analysis,it was found that porous ceramsite were porous materials with rough surfaces.After calcination,the newly formed mineral was silicate calcium feldspar.The heavy metal concentration in the leaching solution of porous ceramsite met the national surface water quality requirements.The treatment of domestic sewage showed that the volumetric loads of COD Cr,NH_(4)^(+)-N,and TN removed by the aerated biofilter were 5.23,0.98,and 0.35 kg/(m^(3)·d),respectively,with removal rates of 85.46%,96.13%,and 32.31%. | Ruigang WANG Shuo WANG Weijie LI Hailong LIU | 2024 | Agricultural Biotechnology2024，13，1： | 0 |

| 17 | MtROP8 is involved in root hair development and the establishment of symbiotic interaction between Medicago truncatula and Sinorhizobium meliloti显示文摘Emerging evidence has demonstrated that ROP GTPases play important roles in symbiosis,but the molecular mechanisms on their regulation in symbiosis are largely unknown.In this study,we showed that MtROP8 is involved in the symbiotic interaction between Medicago truncatula and Sinorhizobium meliloti.Expression analyses showed that MtROP8 was down-regulated in the early infected roots,but significantly up-regulated in nodules compared to the roots.Phenotypic analysis of RNA interference(RNAi)-mediated silencing of MtROP8 revealed that knock-down of MtROP8 expression resulted in various developmental defects of root hairs,including branched hairs,short bulbous root hairs,and even root hairs with apparent swollen bases,which were caused by the modification of the distribution and the levels of reactive oxygen species(ROS).Moreover,infection events were increased in transgenic roots harboring the MtROP8 RNAi construct in response to S.meliloti inoculation,concomitant with enhanced nodulation.These results indicate that MtROP8participates in root hair development and the establishmentof the symbiotic interaction by regulating ROS production and distribution. | Qi Wang Mingjuan Lei Aimin Chen Ruigang Wang Guojing Li Yanzhang Wang | 2014 | Chinese Science Bulletin2014，59，32： | 0 |
