| 1 | Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted. | Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao | 2021 | Cancer Communications2021，41，12： | 3 |

| 3 | 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 |

| 5 | NGD Analysis of Defected Ground and SIW-Matched Structure显示文摘A bandpass negative group delay(NGD)passive circuit based on defect ground structure(DGS)and substrate integrated waveguide(SIW)-matched is developed in the paper.The NGD DGS topology is originally built with notched cells associated with self-matched substrate waveguide elements.The DGS design method is introduced as a function of the geometrical notched and SIW via elements.Then,parametric analyses based on full wave 3-D electromagnetic S-parameter simulations were considered to investigate the influence of DGS physical size effects.The design method feasibility study is validated with fully distributed microstrip circuit prototype.Significant bandpass NGD function performances were validated with 3-D simulations and measurements with−1.69 ns negative group delay value around 2 GHz center frequency over 33.7 MHz NGD bandwidth.Insertion loss is 4.37 dB,and reflection loss reaches 41.5 dB. | GU Taochen WAN Fayu GE Junxiang Lalléchère Sébastien Rahajandraibe Wenceslas Ravelo Blaise | 2023 | Chinese Journal of Electronics2023，32，2： | 0 |
