| 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 | Effect of Huangshukuihua(Flos Abelmoschi Manihot) on diabetic nephropathy:a Meta-analysis显示文摘OBJECTIVE: To assess the efficacy of Huangshukuihua(Flos Abelmoschi Manihot) on diabetic nephropathy(DN).METHODS: Articles were retrieved from Pub Med,EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure Database, Chinese Evidence-Based Medicine Database, and Wanfang Database. Two reviewers independently reviewed the article. Only randomized controlled trials were included and 27 were identified involving 2239 patients(1143 in the treatment group and 1096 in the control group).RESULTS: Huangshukuihua(Flos Abelmoschi Manihot) had a significant effect on renal function by improving blood urea nitrogen and serum creatinine,reducing urine protein(24-h urine protein, and urinary albumin excretion rate), and improving serum albumin level, compared with the control group.CONCLUSION: Our findings suggest that, although the bioactive ingredients and mechanism underlying renal protection are unknown, the role of Huangshukuihua(Flos Abelmoschi Manihot) in the treatment of DN deserves further investigation. | Sun Qin Yang Gangyi Zhang Min Zhang Min Chen Shu Chen Pin | 2015 | Journal of Traditional Chinese Medicine2015，35，1： | 9 |
| 3 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020，33，12： | 8 |

| 10 | Root-associated(rhizosphere and endosphere) microbiomes of the Miscanthus sinensis and their response to the heavy metal contamination显示文摘The plant root-associated microbiomes, including both the rhizosphere and the root endosphere microbial community, are considered as a critical extension of the plant genome. Comparing to the well-studied rhizosphere microbiome, the understanding of the root endophytic microbiome is still in its infancy. Miscanthus sinensis is a pioneering plant that could thrive on metal contaminated lands and holds the potential for phytoremediation applications. Characterizing its root-associated microbiome, especially the root endophytic microbiome, could provide pivotal knowledge for phytoremediation of mine tailings. In the current study, M. sinensis residing in two Pb/Zn tailings and one uncontaminated site were collected. The results demonstrated that the metal contaminant fractions exposed strong impacts on the microbial community structures. Their influences on the microbial community, however, gradually decreases from the bulk soil through the rhizosphere soil and finally to the endosphere, which resulting in distinct root endophytic microbial community structures compared to both the bulk and rhizosphere soil. Diverse members affiliated with the order Rhizobiales was identified as the core microbiome residing in the root of M. sinensis. In addition, enrichment of plant-growth promoting functions within the root endosphere were predicted, suggesting the root endophytes may provide critical services to the host plant. The current study provides new insights into taxonomy and potential functions of the root-associated microbiomes of the pioneer plant, M. sinensis, which may facilitate future phytoremediation practices. | Xiaoxu Sun Benru Song Rui Xu Miaomiao Zhang Pin Gao Hanzhi Lin Weimin Sun | 2021 | Journal of Environmental Sciences2021，33，6： | 3 |

| 13 | SARS-CoV-2 crosses the blood-brain barrier accompanied with basement membrane disruption without tight junctions alteration显示文摘SARS-CoV-2 has been reported to show a capacity for invading the brains of humans and model animals.However,it remains undear whether and how SARS-CoV-2 crosses the blood-brain barrier(BBB).Herein,SARS-CoV-2 RNA was occasionally detected in the vascular wall and perivascular space,as well as in brain microvascular endothelial cells(BMECs)in the infected K18-hACE2 transgenic mice.Moreover,the permeability of the infected vessel was in creased.Furthermore,disin tegrity of BBB was discovered in the infected hamsters by administration of Evans blue.Interestingly,the expression of claudin5,ZO-1,occludin and the ultrastructure of tight junctions(TJs)showed unchanged,whereas,the basement membrane was disrupted in the infected animals.Using an in vitro BBB model that comprises primary BMECs with astrocytes,SARS-CoV-2 was found to infect and cross through the BMECs.Consistent with in vivo experiments,the expression of MMP9 was increased and collagen IV was decreased while the markers for TJs were not altered in the SARS-CoV-2-infected BMECs.Besides,inflammatory responses including vasculitis,glial activation,and upregulated inflammatory factors occurred after SARS-CoV-2 infection.Overall,our results provide evidence supporting that SARS-CoV-2 can cross the BBB in a transcellular pathway accompanied with basement membrane disrupted without obvious alteration of TJs. | Ling Zhang Li Zhou Linlin Bao Jiangning Liu Hua Zhu Qi Lv Ruixue Liu Wei Chen Wei Tong Qiang Wei Yanfeng Xu Wei Deng-Hong Gao Jing Xue Zhiqi Song Pin Yu Yunlin Han Yu Zhang Xiuping Sun Xuan Yu Chuan Qin | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 2 |
| 14 | Occupational Health Risk Assessment of Benzene,Toluene,and Xylene in Shanghai显示文摘Objective This study was designed to conduct a retrospective and systematic occupational health risk assessment(OHRA)of enterprises that used benzene,toluene,and xylene(BTX)in Shanghai,China.Methods All data for the study were obtained from 1,705 occupational health examination and evaluation reports from 2013 to 2017,and a semiquantitative model following Chinese OHRA guidelines(GBZ/T 298-2017)was applied for the assessment.Results The selected enterprises using BTX were mainly involved in manufacturing of products.Using the exposure level method,health risk levels associated with exposure to BTX were classified as medium,negligible,or low.However,the risk levels associated with benzene and toluene were significantly different according to job types,with gluers and inkers exhibiting greater health risks.For the same job type,the health risk levels assessed using the comprehensive index method were higher than those using the exposure level method.Conclusion Our OHRA reveals that workers who are exposed to BTX still face excessive health risk.Additionally,the risk level varied depending on job categories and exposure to specific chemicals.Therefore,additional control measures recommended by OHRA guidelines are essential to reduce worker exposure levels. | WANG Tong Shuai SONG Bo SUN Qing Hua LIN Yong Xin SUN Yuan SUN Pin JIA Xiao Dong William W.Au MEI Can Hua XIA Zhao Lin | 2021 | Biomedical and Environmental Sciences2021，34，4： | 2 |

| 17 | An Efficient Second-Order Convergent Scheme for One-Side Space Fractional Diffusion Equations with Variable Coefficients显示文摘In this paper,a second-order fnite-diference scheme is investigated for time-dependent space fractional difusion equations with variable coefcients.In the presented scheme,the Crank-Nicolson temporal discretization and a second-order weighted-and-shifted Grünwald-Letnikov spatial discretization are employed.Theoretically,the unconditional stability and the second-order convergence in time and space of the proposed scheme are established under some conditions on the variable coefcients.Moreover,a Toeplitz preconditioner is proposed for linear systems arising from the proposed scheme.The condition number of the preconditioned matrix is proven to be bounded by a constant independent of the discretization step-sizes,so that the Krylov subspace solver for the preconditioned linear systems converges linearly.Numerical results are reported to show the convergence rate and the efciency of the proposed scheme. | Xue-lei Lin Pin Lyu Michael KNg Hai-Wei Sun Seakweng Vong | 2020 | Communications on Applied Mathematics and Computation2020，2，2： | 1 |

| 19 | 基于上皮–间质转化标志物的循环肿瘤细胞表型检测对HER2阴性转移性乳腺癌一线化疗的预后意义显示文摘背景与目的上皮–间质转化(epithelia-mesenchymal,EMT)参与肿瘤细胞的转移,并且对基于上皮细胞黏附分子的循环肿瘤细胞(circulating tumor cells,CTCs)检测技术提出了挑战,CTCs已被证实是转移性乳腺癌的预后指标。虽然有证据表明基于EMT标志物的CTCs异质性与疾病进展相关,但在临床应用方面尚无统一的参考标准。本研究旨在评估基于EMT的动态CTCs检测对转移性乳腺癌患者的预后意义。方法我们从CAMELLIA III期前瞻性研究中招募了108例人表皮生长因子受体2阴性转移性乳腺癌患者,并应用CanPatrol CTC富集技术检测外周血中不同亚型的CTCs(包括上皮型CTCs、混合型上皮/间质CTCs和间质型CTCs)。应用1年无进展生存(progression-free survival,PFS)率作为界值分别寻找CTC总数和间质CTCs比例的受试者工作曲线来确定最佳阈值,并采用Kaplan-Meier分析和Cox比例风险回归分析验证综合考虑CTC总数和间质型CTCs比例制定的诊断标准的预后价值。结果CTC总数的最佳阈值为9.5[曲线下面积(area under the curve,AUC)=0.538,95%置信区间(confidence interval,CI=0.418–0.657)]及间质CTCs比例为10.7%(AUC=0.581,95%CI:0.463–0.699)作为预测1年PFS率的界值。我们采用CTC总数≥10/5 mL且间质CTCs比例>10.7%的联合标准预测PFS。符合联合标准的患者的中位PFS显著短于不符合标准的患者(6.2个月vs.9.9个月,P=0.010)。根据该标准和显著的临床病理学特征绘制列线图,C指数为0.613(P=0.010)。结论CTC总数和间质CTCs比例的联合标准可用于监测转移性乳腺癌患者的治疗耐药性和预测患者预后。 | 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 | 癌症2019，38，9： | 1 |
| 20 | Association of the genetic polymorphism of EPHX1 and EPHX2 with the susceptibility to chronic benzene poisoning显示文摘The aim of this study was to explore the association of the genetic polymorphism of EPHX1 and EPHX2 with the susceptibility to chronic benzene poisoning(CBP).A case-control study of 268 patients with CBP and 268 healthy workers matched by age and sex,all of whom were occupationally exposed to benzene,was conducted.The single nucleotide polymorphisms(SNPs,rs2854451,rs3738047,rs2234922 and rs1051741)of EPHX1 gene and the SNP(rs751141)of EPHX2 gene were tested by the TaqMan PCR method.In the subjects carrying the genotype of EPHX1 rs3738047 GG,the risk of CBP was decreased in the individuals simultaneously carrying EPHX1 rs2234922 G(P=0.02).Alternatively,in the subjects carrying the genotype of EPHX1 rs2234922 AA,the risk of CBP was increased in the individuals simultaneously carrying the allele of EPHX2 rs751141A(P=0.03).It was also found that there were potential interactions between alcohol consumption and the polymorphism of EPHX1 rs1051741(x_(H)^(2)=5.28,P=0.02)or rs2234922(x_(H)^(2)=6.71,P=0.01).Compared to individuals with EPHX1 rs1051741 CC or rs2234922 AA genotype in the drinkers,the risk of CBP in those carrying genotypes of EPHX1 rs1051741 CT+TT or rs2234922 AG+GG was decreased,respectively(P=0.04,P<0.01).Haplotype analysis of polymorphisms in EPHX1 showed that the risk of CBP was increased in the subjects with haplotype 2(rs2854451-A,rs3738047-G,rs2234922-A,rs1051741-C)or haplotype 4(rs2854451-G,rs3738047-A,rs2234922-G,rs1051741-T),but decreased in those with haplotype 6(rs2854451-G,rs3738047-G,rs2234922-G,rs1051741-T)or haplotype 10(rs2854451-A,rs3738047-A,rs2234922-G,rs1051741-T),respectively.Logistic regression analysis revealed that smoking might play a role in modifying the risk of CBP(OR=0.313,95%CI:0.123–0.794,P=0.015).The genetic polymorphism in EPHX1 may be associated with the risk of CBP in the Chinese occupational population and further research is needed for the association between the genetic polymorphism in EPHX2 and the susceptibility to CBP. | SUN Pin ZHANG Zhongbin WU Fen WAN Junxiang JIN Xibeng XIA Zhaolin | 2007 | Frontiers of Medicine2007，1，3： | 1 |
