| 1 | 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 |
| 2 | Phase Ⅱ study of apatinib in combination with oral vinorelbine in heavily pretreated HER2-negative metastatic breast cancer and clinical implications of monitoring ctDNA显示文摘Objective:Apatinib is an oral TKI targeting VEGFR-2.Single-agent apatinib treatment has been shown to produce an objective response in patients with pretreated m BC.Oral vinorelbine also holds promise as a treatment of choice in patients with m BC.This study aimed to investigate the efficacy and safety of the oral vinorelbine-apatinib combination in patients with pretreated m BC.In addition,we detected gene variants in ct DNA to explore the therapeutic implications.Methods:This study enrolled patients with HER2-negative m BC who were pretreated with anthracycline/taxanes.Patients were treated with apatinib at 500 mg/425 mg daily plus oral vinorelbine 60 mg/m2 on days 1,8,and 15 of every cycle(3 weeks).The primary endpoint was PFS.The secondary endpoints were ORR,CBR,OS,and safety.Patients eligible for ct DNA detection were evaluated before and during treatment.Results:Forty patients were enrolled.The median PFS was 5.2 months(95%CI,3.4–7.0 months),and the median OS was 17.4 months(95%CI,8.0–27.0 months).The ORR was 17.1%(6/35),and the CBR was 45.7%(16/35).The most common AEs included gastrointestinal reaction,myelosuppression,and hypertension.In 20 patients,ct DNA was detected at baseline and during treatment.A significant difference was found in PFS for undetected vs.detected baseline ct DNA(13.9 months vs.3.6 months,P=0.018).Conclusions:All-oral therapy with apatinib plus vinorelbine displayed objective efficacy in patients with heavily pretreated HER2-negative m BC,with acceptable and manageable toxicity profiles.Patients with no gene variant detected and lower variant allele frequencies in ct DNA at baseline showed longer PFS. | Anjie Zhu Peng Yuan Nanlin Hu Mingzhou Li Wenmiao Wang Xue Wang Jian Yue Jiayu Wang Yang Luo Fei Ma Pin Zhang Qing Li Binghe Xu Shanbo Cao Giuseppe Lippi Yoichi Naito Mohammed A.Osman Gustavo N.Marta Gianluca Franceschini Armando Orlandi | 2021 | Cancer Biology & Medicine2021，18，3： | 4 |
| 3 | 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 | Effects of Multiple Cleaning and Disinfection Interventions on Infectious Diseases in Children: A Group Randomized Trial in China显示文摘Objective To assess the effectiveness of multiple cleaning and disinfection interventions in the homes and kindergartens, in reducing gastrointestinal and respiratory illnesses of children. Methods From October 2010 to September 2011, we performed a prospective, controlled study in China. 408 children under 5 years old were recruited and group randomized into intervention and control groups. Families and kindergartens in the intervention group were provided with antibacterial products for hand hygiene and surface cleaning or disinfection for one year. Each child's illness symptoms and sick leave were recorded every day. Results A total of 393 children completed the study, with similar baseline demographics in each of the 2 groups. Except for abdominal pain, the odds of symptoms(fever, cough and expectoration, runny nose and nasal congestion, diarrhea), illness(acute respiratory illness and gastrointestinal illness), and sick leave per person each month were significantly reduced by interventions. The rates of fever, diarrhea, acute respiratory illness, gastrointestinal illness and sick leave per person per year were significantly decreased as well. Conclusion Not only the acute respiratory and gastrointestinal illness but the sick leave rate in children were significantly reduced by multiple interventions. | BAN Hai Qun LI Tao SHEN Jin LI Jin PENG Pin Zhang YE Heng Ping ZHANG Liu Bo | 2015 | Biomedical and Environmental Sciences2015，28，11： | 2 |
| 6 | 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 |

| 8 | Improving the efficiency of hybrid combination preparation in rice breeding by a modified flowering stimulant显示文摘The utilization of hybrid vigor is an important breakthrough in the history of rice breeding.To select the best hybrid combinations,breeders manually perform extensive testing of hybridizations between restorer and sterile lines,which is a laborious and time-consuming process.Here,we report that a modified flowering stimulant containing methyl jasmonate(MeJA),6-benzylamine adenine and kinetin effectively promotes the flowering and seed set of male-sterile rice lines.Different concentrations of the ingredients were tested to identify an optimal formulation.Seed quality evaluation indicated that hybrid seeds from plants sprayed with the flowering stimulant had a higher germination rate than seeds from plants prepared by glume-cutting.In summary,the modified flowering stimulant described in this study may help reduce the labor requirement associated with hybrid rice breeding and improve yield and efficiency. | Ling Zheng Shangxing Zhang Fengyin Xue Yifan Yun Pin Liu Hua Yuan Weilan Chen Peng Qin Yuping Wang Bingtian Ma Shigui Li Yong Chen Bin Tu | 2020 | International Journal of Agricultural and Biological Engineering2020，13，3： | 1 |

| 11 | Clinical practice guideline for body composition assessment based on upper abdominal magnetic resonance images annotated using artificial intelligence显示文摘Introduction Upper abdominal magnetic resonance(MR)imaging is appropriate for body composition analysis.111 Especially for individuals with obesity,it is of great value to quantify the hepatic proton density fat fraction(PDFF)and the amount of abdominal adipose tissue during clinical evaluation and for research on obesity-related risks.Analytical results may be used to determine the optimal choice of surgical procedure and evaluate treatment outcomes.Multiple artificial intelligence(Al)algorithms and systems have been developed for the automated measurement of body composition.The basis of Al development and application is to have uniform standards for clinical data acquisition and management.The uneven quality ofMR images is one ofthe major obstacles to Al system development and analytical results.A standardized process of MR scanning and clinical data management is urgently needed. | Han Lv Mengyi Li Zhenchang Wang Dawei Yang Hui Xu Juan Li Yang Liu Di Cao Yawen Liu Xinru Wu He Jin Peng Zhang Liqin Zhao Rixing Bai Yunlong Yue Bin Li Nengwei Zhang Mingzhu Zou Jinghai Song Weibin Yu Pin Zhang Weijun Tang Qiyuan Yao Liheng Liu Hui Yang Zhenghan Yang Zhongtao Zhang National Clinical Research Center for Digestive Diseases in Beijing Friendship Hospital,Capital Medical University Beijing Quality Control and Improvement Center of Medical Imaging National Health Commission Capacity Building and Continuing Education Center,Chinese College of Metabolic and Bariatric Surgeons Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery | 2022 | Chinese Medical Journal2022，，6： | 1 |
| 12 | 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 |
| 13 | Enhancing the cycling stability of Na-ion batteries by bonding MoS2 on assembled carbon-based materials显示文摘Room temperature Na-ion batteries(SIBs) show great potential for use as renewable energy storage systems.However, the large-scale application of SIBs has been hindered by the lack of an ideal SIBs anode material. We synthesized MoS2 on carbonized graphene-chitosan(G-C) using the hydrothermal method. The strong interaction between the MoS2 and the G-C greatly improved the electron transport rate and maintained the structural stability of the electrode, which lead to both an excellent rate capability and long cycle stability. The G-C monolith was proven to enhance the electrical conductivity of the composites and served as a matrix for uniformly dispersing active MoS2 nanosheets(NSs), as well as being a buffer material to adapt to changes in volume during the cycle.Serving as an anode material for SIBs, the MoS2-G-C electrode showed good cycling stability(527.3mAh g-1 at100 m A g-1 after 200 cycles), excellent rate capability, and a long cycle life(439.1 m Ah g-1 at 1 A g-1 after 200 cycles). | Pin Song Jun Di Lixing Kang Manzhang Xu Bijun Tang Jun Xiong Jiewu Cui Qingsheng Zeng Jiadong Zhou Yongmin He Qundong Fu Juan Peng Shasha Guo Bo Lin Jingyu Zhang Peng Meng Zheng Liu | 2019 | Nano Materials Science2019，1，4： | 0 |
| 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 | Combined chemo-endocrine therapy as a potential new option for HR+/HER2−advanced breast cancer:a prospective study of fulvestrant plus oral vinorelbine显示文摘Objective:Endocrine therapy with fulvestrant has shown synergistic antitumor effects with some chemotherapy drugs in vitro.This study evaluated the efficacy and safety of fulvestrant with vinorelbine in patients with hormone receptor positive(HR+)/human epidermal growth factor receptor-2-negative(HER2−)recurrent or metastatic breast cancer.Methods:Patients were intramuscularly administered fulvestrant 500 mg(day 1 per cycle for 28 days)and oral vinorelbine(60 mg/m2 on days 1,8,and 15 of each cycle).The primary endpoint was progression-free survival(PFS).Secondary endpoints included overall survival,objective response rate,disease control rate,duration of response,and safety.Results:A total of 38 patients with HR+/HER2−advanced breast cancer included in the study were followed up for a median time of 25.1 months.The overall median PFS was 9.86 months[95%confidence interval(CI)7.2-23.13],and the median PFS of the first-line and the second-line treatment population was 20.73 months(95%CI 9.82 to NR)and 4.27 months(95%CI 3.68 to NR),respectively.Most adverse events reported were of grade 1/2,and none were of grade 4/5.Conclusions:This is the first exploratory study of a fulvestrant and oral vinorelbine regimen in the treatment of HR+/HER2−recurrent and metastatic breast cancer.The combination chemo-endocrine therapy was efficacious,safe,and promising for patients with HR+/HER2−advanced breast cancer. | Xue Wang Jian Yue Yikun Kang Zhong Dai Jie Ju Jiayu Wang Pin Zhang Fei Ma Binghe Xu Peng Yuan | 2023 | Cancer Biology & Medicine2023，20，4： | 0 |
| 16 | Electrochemistry and In-situ Spectroelectrochemistry Studies of Carbazole and 9-Ethylcarbazole显示文摘Mechanisms of electron transfer of carbazole (CZ) and 9-ethylcarbazole (ECZ) were studied by electrochemistry and in-situ spectroelectrochemistry. The result indicated that the electrochemical reaction mechanism of ECZ was the same as that of CZ. Both of them undergo ECE process: the initial step is removal of one electron to generate very reactive cation radical, this species then proceeded by deprotonation-coupling reaction to form the corresponding dimer, which was oxidized continuously. | Zi Pin ZHANG Bao Kang JIN Yu Peng TIAN Shi Jun WANG | 2005 | Chinese Chemical Letters2005，16，12： | 0 |
