| 1 | Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only. | Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao | 2019 | Cell Research2019，29，2： | 16 |
| 2 | Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers. | Rui Chen Shancheng Ren 无 Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun | 2014 | Asian Journal of Urology2014，1，1： | 13 |

| 4 | Clinical characteristics and effectiveness of antiviral agents in hospitalized children with infectious mononucleosis in China:A multicenter retrospective study显示文摘Importance:The clinical characteristics of infectious mononucleosis(IM)in Chinese children have not been evaluated in multicenter studies,and the effectiveness of antiviral treatment are controversial.Objective:To investigate the clinical characteristics of Chinese children with IM and current status of antiviral therapy for affected patients.Methods:Hospitalized patients with IM were enrolled between 2018 and 2020 in five children’s hospitals in China.The clinical characteristics were compared among four age groups:<3 years,3-<6 years,6-<10 years,and≥10 years.The clinical characteristics of IM and effectiveness of antiviral therapy were compared among patients receiving acyclovir(ACV),ganciclovir(GCV),and no antiviral therapy(i.e.,non-antiviral group).Results:In total,499 patients were analyzed;most patients were 3-<6 years of age.The most common symptoms and signs included fever(100%),lymphadenopathy(98.6%),pharyngitis(86.4%),eyelid edema(76.8%),and snoring(72.9%).There were significant differences in rash,hepatomegaly,and liver dysfunction among the four age groups.Patients aged<3 years had a lower incidence of liver dysfunction and a higher incidence of rash.Among the 499 patients,50.1%were treated with GCV,26.3%were treated with ACV,and 23.6%received no antiviral therapy.Compared with the non-antiviral group,patients in the ACV and GCV groups had longer durations of fever(P<0.001).There were no significant differences in the incidences of complications among the three treatment groups.Interpretation:The incidence of IM in Chinese children peaked at 3-<6 years of age.Clinical features of IM varied according to age.Patients receiving antiviral therapy exhibited more serious clinical manifestations than did patients without antiviral therapy.The effectiveness of antiviral therapy for IM requires further analysis. | Huili Hu Huiling Deng Jing Bi Yi Xu Shuangjie Li Yue Xie Xinrong Sun Dongmeng Wang Xufang Li Wenxian Ouyang Bing Hu Yufeng Zhang He Tang Chunxiao Fang Hui Zhang Lingyun Guo Chen Wang Tianyi Wang Fengxia Yang Tao Jiang Zhengde Xie Gang Liu | 2021 | Pediatric Investigation2021，5，3： | 12 |
| 5 | Percent free prostate-specific antigen for prostate cancer diagnosis in Chinese men with a PSA of 4.0-10.0 ng/mL:Results from the Chinese Prostate Cancer Consortium显示文摘Objective:To test the diagnostic performance of percent free prostate-specific antigen(%fPSA)in predicting any prostate cancer(PCa)and high-grade prostate cancer(HGPCa)in a retrospective multi-center biopsy cohort with a PSA level of 4.0e10.0 ng/mL in China.Methods:Consecutive patients with a PSA of 4.0-10.0 ng/mL who underwent transrectal ultrasound-guided biopsy were enrolled at 16 Chinese medical centers from January 1st,2010 to December 31st,2013.Total and free serum PSA determinations were performed using three types of electro-chemiluminescence immunoassays recalibrated to the World Health Organization(WHO)standard.The diagnostic accuracy of PSA,%fPSA,and %fPSA in combination with PSA(%fPSA t PSA)was determined using the area under the receiver operating characteristic(ROC)curve(AUC).Results:A total of 2310 consecutive men with PSA levels between 4.0 and 10.0 ng/mL were included,and the detection rate of PCa was 25.1%.The AUC of%fPSA and %fPSA t PSA in predicting any PCa was superior to PSA alone in men aged≥60 years(0.623 vs.0.534,p<0.0001)but not in men aged 40e59 years(0.517 vs.0.518,p=0.939).Similar result was yield in predicting HGPCa.Conclusion:In a clinical setting of Chinese men with 4.0e10.0 ng/mL PSA undergoing initial prostate biopsy,adding %fPSA to PSA can moderately improve the diagnostic accuracy for any PCa and HGPCa compared with PSA alone in patients≥60 but not in patients aged 40-59 years. | Rui Chen Liping Xie Xiaobing Cai Yiran Huang Liqun Zhou Lulin Ma Xu Gao Chuanliang Xu Shancheng Ren Pengfei Shao Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Li Lu Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tie Zhou Fubo Wang Biming He Yinghao Sun | 2015 | Asian Journal of Urology2015，2，2： | 8 |
| 6 | Gene diagnosis and targeted breeding for blast-resistant Kongyu 131without changing regional adaptability显示文摘The fungus Magnaporthe oryzae threatens the rice production of Kongyu 131 (KY131),a leading japonica variety in Northeast China.In this study,two rice lines,KP1 and KP2-Hd1,were obtained by introgressing the blast resistance genes Pi1 and Pi2 into KY131,respectively.However,both lines headed later than KY131.RICE60K SNP array analysis showed that Hd1 closely linked to Pi2 was introgressed into KP2-Hd1,and the linkage drag of Hd1 was broken by recombination.On the other hand,no known flowering genes were introgressed into KP1.Gene diagnosis by resequencing six flowering genes showed that KP1 carried functional Hd16 and Ghd8 alleles.Due to its suppression role in heading under long-day conditions,Ghd8 was chosen as the target for gene editing to disrupt its function.Four sgRNAs targeting different sites within Ghd8 were utilized to induce large-deletion mutations,which were easy to detect via agarose gel electrophoresis.All the ghd8-mutated KP1 lines were resistant to rice blast disease and headed earlier than the control KP1,even than KY131,under natural long-day conditions,which ensures its growth in Northeast China.This study confirmed that a combination of gene diagnosis and targeted gene editing is a highly efficient way to quickly eliminate undesired traits in a breeding line. | Xiangchun Zhou Gonghao Jiang Longwei Yang Lei Qiu Ping He Chunxiao Nong Yunyue Wang Yuqing He Yongzhong Xing | 2018 | Journal of Genetics and Genomics2018，45，10： | 7 |
| 7 | Structure and property of metal melt Ⅳ——Evolution of titanium melt residual bond structure and its effect on dynamic viscosity显示文摘Based on the concept of melt residual bonds, a calculating model quantitatively describing the evolution of the residual bond structure of titanium melt at the melting point or in a certain range above the melting point was established; i.e., both the size dS and the bond number n of the residual bond structure decrease monotonously with the increase of temperature. By mathematical deduction, a linear relationship between the residual bond structure size dS and the dynamic viscosity of Titanium melt was revealed, i.e., = 0.876 + 0.471·dS, which is of great significance to the investigation of the relationship between the melt microstructure and the macroscopic properties of metals with high melting temperature. | MI GuangBao CAO JingXia HUANG Xu CAO ChunXiao LIPeiJie HE LiangJu | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，8： | 3 |
| 8 | Overexpression of rice OsLOL2 gene confers disease resistance in tobacco to Pseudomonas syringae pv. tabaci显示文摘LSD1-related proteins of Arabidopsis with LSD1-like zinc finger domains regulate disease resistance and programmed cell death (PCD). We cloned a rice OsLOL2 gene, orthologous to LSD1 of Arabidopsis and expressed it in a tobacco plant. Transgenic tobacco lines displayed enhanced disease resistance to a virulent bacterium Pseudomonas syringae pv. tabaci (Pst). RT-PCR analysis showed that overexpression of OsLOL2 in transgenic tobacco lines resulted in upregulation of two pathogenesis-related (PR) protein genes, PR2 and PR5. Our results suggest that overexpression of OsLOL2 in transgenic tobacco enhances the resistance through the induction of PR pro- teins and hypersensitive response-like reaction. | Khizar Hayat Bhatti Chunxiao Xu Jiahe Wu Chaozu He | 2008 | Progress in Natural Science:Materials International2008，18，7： | 2 |

| 10 | MXene and MXene-based materials for lithium-sulfur batteries显示文摘Lithium-sulfur(Li–S)batteries are regarded as potential alternatives to lithium-ion batteries due to their extremely high theoretical energy density.Nevertheless,Li–S batteries still suffer from low coulombic efficiency,low sulfur utilization,and poor cycling life,which hinder their further applications.To obtain ideal Li–S cells,intensive work has been dedicated to improve the conductivity of the electrode,inhibiting the shuttle of lithium polysulfides,and promoting the redox of sulfur.Two-dimensional transition metal carbides,nitrides or carbonitrides,also known as MXenes,attracting significant research interest in Li–S batteries due to their high conductivity,abundant active sites,layered structure and adjustable surface chemistry.In this review,we summarize the partial etching methods of MXenes with different surface terminations,the role of MXenes in Li–S batteries and MXene-based composites designed for Li–S batteries based on interfacial chemistry and interlayer structure.In the end,we also propose the perspectives of MXenes for Li–S batteries. | Youquan Zhang Cheng Ma Weitao He Chunxiao Zhang Liangjun Zhou Gao Wang Weifeng Wei | 2021 | Progress in Natural Science:Materials International2021，31，4： | 1 |
| 11 | Effect of defects and remediation measures on the internal forces caused by a local thickness reduction in the tunnel lining显示文摘This study presents a case history of a tunnel lining with an insufficient thickness.The effect of the defects resulting from the insuf-ficient thickness of the secondary lining and their locations on the internal forces are discussed based on numerical analysis.The results show that defects increase the number of inflection points in the defect region.The increased maximum bending moment is located on the air side of the secondary lining around the defect region.The defects near the crown of the secondary lining have the most significant influence on the internal forces of the primary and secondary linings,while the defects near the sidewall of the secondary lining have a limited influence on the internal forces of the lining.A remediation measure consisting of the installation of a tertiary lining is proposed and its efficiency is analyzed.The tertiary lining significantly reduces the bending moment of the secondary lining and the axial force of the primary lining.The effect of the thickness and location of the tertiary lining on the tunnel performance is discussed. | Ping Lu Dongwang Qiao Chunxiao Wu Shun Wang Xiaopei He Wenjun Zhang Haizuo Zhou | 2022 | Underground Space2022，7，1： | 1 |
| 12 | p38α has an important role in antigen cross-presentation by dendritic cells显示文摘The role of the p38 signaling pathway in the innate and adaptive immune responses has been well documented,especially in inflammatory cytokine production by dendritic cells(DCs).However,whether the p38 signaling pathway affects the important antigen(Ag)presentation function of DCs remains largely unknown.In this study,we reported that the deletion of p38αresulted in an impaired cross-presentation ability of CD8^(+) conventional DCs(cDCs)and a reduction in the direct presentation ability of CD8−cDCs ex vivo.Further study revealed that p38αhad a crucial role in Ag processing by CD8^(+) cDCs but did not affect the Ag uptake or co-stimulation of T cells.Moreover,p38αdeficiency led to reduced cross-priming of T cells in vivo.The production of the IL-12p40 and IL-12p70 cytokines by p38α-deficient cDCs was also significantly reduced.Our study identified a new role for p38αin modulating the important antigen cross-presentation function of DCs. | Yifan Zhou Jianfeng Wu Chunxiao Liu Xueheng Guo Xinyi Zhu Yuan Yao Yuhao Jiao Peng He Jiahuai Han Li Wu | 2018 | Cellular & Molecular Immunology2018，15，3： | 1 |
| 13 | Effects of interlayer coupling on the excitons and electronic structures of WS_(2)/hBN/MoS_(2) van der Waals heterostructures显示文摘Inserting hexagonal boron nitride(hBN)as barrier layers into bilayer transition metal dichalcogenides heterointerface has been proved an efficient method to improve two dimensional tunneling optoelectronic device performance.Nevertheless,the physical picture of interlayer coupling effect during incorporation of monolayer(1L-)hBN is not explicit yet.In this article,spectroscopic ellipsometry was used to experimentally obtain the broadband excitonic and critical point properties of WS_(2)/MoS_(2)and WS_(2)/hBN/MoS_(2)van der Waals heterostructures.We find that 1L-hBN can only slightly block the interlayer electron transfer from WS_(2)layer to MoS_(2)layer.Moreover,insertion of 1L-hBN weakens the interlayer coupling effect by releasing quantum confinement and reducing efficient dielectric screening.Consequently,the exciton binding energies in WS_(2)/hBN/MoS_(2)heterostructures blueshift comparing to those in WS_(2)/MoS_(2)heterostructures.In this exciton binding energies tuning process,the reducing dielectric screening effect plays a leading role.In the meantime,the quasi-particle(QP)bandgap remains unchanged before and after 1L-hBN insertion,which is attributed to released quantum confinement and decreased dielectric screening effects canceling each other.Unchanged QP bandgap as along with blueshift exciton binding energies lead to the redshift exciton transition energies in WS_(2)/hBN/MoS_(2)heterostructures. | Xudan Zhu Junbo He Rongjun Zhang Chunxiao Cong Yuxiang Zheng Hao Zhang Songyou Wang Haibin Zhao Meiping Zhu Shanwen Zhang Shaojuan Li Liangyao Chen | 2022 | Nano Research2022，15，3： | 1 |
| 14 | Survival after radical cystectomy for bladder cancer:Multicenter comparison between minimally invasive and open approaches显示文摘Objective:To investigate oncological outcomes in patients with bladder cancer who underwent minimally invasive radical cystectomy(MIRC)or open radical cystectomy(ORC).Methods:We identified patients with bladder cancer who underwent radical cystectomy(RC)in 13 centers of the Chinese Bladder Cancer Consortium(CBCC).Perioperative outcomes were compared between MIRC and ORC.The influence of surgical approaches on overall survival(OS)and cancer-specific survival(CSS)in the entire study group and subgroups classified according to pathologic stage or lymph node(LN)status was assessed with the log-rank test.Multivariable Cox proportional hazard models were used to evaluate the association among OS,CSS and risk factors of interest.Results:Of 2098 patients who underwent RC,1243 patients underwent MIRC(1087 laparoscopic RC and 156 robotic-assisted RC,respectively),while 855 patients underwent ORC.No significant differences were noted in positive surgical margin rate and 90-day postoperative mortality rate.MIRC was associated with less estimated blood loss,more LN yield,higher rate of neobladder diversion,longer operative time,and longer length of hospital stay.There was no significant difference in OS and CSS according to surgical approaches(pZ0.653,and 0.816,respectively).Subgroup analysis revealed that OS and CSS were not significantly different regardless of the status of extravesical involvement or LN involvement.Multivariable Cox regression analyses showed that the surgical approach was not a significant predictor of OS and CSS.Conclusions:Our study showed that MIRC was comparable to conventional ORC in terms of OS and CSS. | Weibin Xie Junming Bi Qiang Wei Ping Han Dongkui Song Lei Shi Dingwei Ye Yijun Shen Xin Gou Weiyang He Shaogang Wang Zheng Liu Jinhai Fan Kaijie Wu Zhiwen Chen Xiaozhou Zhou Chuize Kong Yang Liu Chunxiao Liu Abai Xu Baiye Jin Guanghou Fu Wei Xue Haige Chen Tiejun Pan Zhong Tu Tianxin Lin Jian Huang | 2020 | Asian Journal of Urology2020，7，3： | 1 |

| 16 | Relationship between the types of binary alloy phase diagrams of Ⅷ and IB group elements and the Mendeleev numbers显示文摘The relationship between the types of binary alloy phase diagrams of VIII and IB group elements and the Mendeleev numbers was discussed for the first time using the VIII and IB group elements as solvent metals (A) and the other elements as solute metals (B), basesd on their alloy phase diagram types. The Mendeleev numbers of the solvent metals and the solute metals were expressed as MA, and MB, respectively. A two-dimension map of MA/MB was drawn. It is indicated that there is an oblique line in the map, which divides the binary alloy phase diagram types of solvent metals into two symmetry parts, the phase diagram types of the other elements with solvent metals located at the above or down of the line respectively, while on the line, △M=0. The phase diagrams between the solvent metals basically are simple systems, mainly belong to the types of continues solid solution and the peritectic (about 40% for each type). The solvent metals can be divided into three groups: Co, Jr, Rh, Ni, Pt, and Pd as the first group; Ag, Au, and Cu as the second group; and Fe, Os, and Ru as the third group. The characteristics of the phase diagrams formed between the elements in each group were discussed. About 80% phase diagrams belong to complex systems and less than 20% belong to the simple systems. The regular variation of the chemical scale, the metallic radii of the atoms, the number of valence electrons, and the first ionization energy with the Mendeleev numbers and the crystal structure were introduced as well. | HE Chunxiao, LI Guanfang, LUO Yanbo, and LI Yanan Kunming Institute of Precious Metals, Kunming 650221, China | 2002 | Rare Metals2002，21，1： | 0 |
| 17 | uSensing:a Universal Platform to Support Smartphones Accessing Wireless Sensor Networks显示文摘This paper presents a universal platform 'uSensing' to support smartphones to communicate with sensor nodes in Wireless Sensor Networks (WSNs).Since phones have different CPU processers and operating systems,it is a challenge to merge these heterogeneities and develop such a universal platform.In this paper,we design both hardware and software to support the 'universal' feature of uSensing:1) 'uSD' card:an IEEE 802.15.4 physical communication card with SD interface;2) 'uSinkWare':a WSNs middleware running on smartphones.Integrated with uSD card and uSinkWare,phones become mobile data sinks to access into WSNs and parse messages from sensor nodes.We demonstrate the proposed uSensing platform in a commercial smartphone to connect with our WSNs testbed,and validate that the smartphone has the same WSNs functions as commercial fixed sink.Additionally,we evaluate the performance of uSensing platform through measuring phone's CPU load and power consumption,and analyze the performance of these metrics theoretically.The results suggest that the phone-based mobile sink has enough capability to serve as a mobile sink of WSNs and can work up to twenty hours due to low power consumption. | He Nengqiang Jiang Chunxiao Dong Yuhan Ren Yong Chen Canfeng | 2012 | China Communications2012，9，4： | 0 |

| 19 | Characterization of Flame Retardancy and Oil-Water Separation Capacity of Superhydrophobic Silylated Melamine Sponges显示文摘A silylated melamine sponge(SMS)was prepared by two simple steps,namely,immersion and dehydration of a melamine sponge coated with methyltrichlorosilane.The silylated structure of SMS was characterized by FT-IR(Fourier-transform infrared)spectroscopy,SEM(Scanning electron microscopy)and in terms of water contact angles.Its oil-water absorption and separation capacities were measured by FT-IR and UV-visible spectrophoto-metry.The experimental results have shown that oligomeric silanol covalently bonds by Si-N onto the surface of melamine sponge skeletons.SMS has shown superhydrophobicity with a water contact angle exceeding 150°±1°,a better separation efficiency with regard to diesel oil(by 99.31%(wt/wt%)in oil-water mixture and even up to 99.99%(wt/wt%)for diesel oil in its saturated aqueous solution.Moreover,SMS inherited the intrinsicflame retardancy of the melamine sponge.In general,SMS has shown superhydrophobicity,high porosity,excellent selectivity,remarkable recyclability,and better absorption capacity for various oils and organic solvents,and a high separation efficiency for oil in saturated aqueous solutions. | Yongchun Liu Ni Qiao Yanli Yang Yanchun Li Chunxiao He Siyang Wang Chengcheng Liu Ruixia Lei Wang Li Wenwen Gao | 2024 | Fluid Dynamics & Materials Processing2024，20，2： | 0 |
| 20 | Prognostic value of the 21-gene recurrence score in ER-positive,HER2-negative,node-positive breast cancer was similar in nodenegative diseases:a single-center study of 800 patients显示文摘Multi-gene assays have emerged as crucial tools for risk stratification in early-stage breast cancer.This study aimed to evaluate the prognostic significance of the 21-gene recurrence score(RS)in Chinese patients with pN0-l,estrogen receptor-positive(ER+),human epidermal growth factor receptor 2-negative(HER2)breast cancer.Among 800 patients recruited between 2009 and 2016,the median RS was 24(0-69),with 27.4%,46.8%,and 25.9%patients classified into low-,intermediate-,and high-risk groups.Cox regression analysis demonstrated that the high-risk category was associated with significantly higher odds of invasive disease-free survival(IDFS)and distant disease-free survival(DDFS)events compared with the low-risk category(IDFS:HR=2.450,95%Cl 1.017-5.902,P=0.046;DDFS:HR=2.829,95%Cl 1.013-7.901,P=0.047).No significant association between RS category and overall survival(OS)was found(intermediate vs.low:HR=1.244,95%Cl 0.292-5.297,P=0.768;high vs.low:HR=2.933,95%Cl 0.759-11.327,P=0.119).RS,as a continuous variable,was a highly significant predictor for IDFS(HR=1.028,95%Cl 1.010-1.047,P=0.002),DDFS(HR=1.030,95%Cl 1.010-1.051,P=0.003),and OS(HR=1.034,95%Cl 1.007-1.063,P=0.014).Our findings suggested that RS may predict IDFS in Chinese patients with ER+/HER2 breast cancer with NO or N1 disease. | Jiayi Wu Weiqi Gao Xiaosong Chen Chunxiao Fei Lin Lin Weiguo Chen Ou Huang Siji Zhu Jianrong He Yafen Li Li Zhu Kunwei Shen | 2021 | Frontiers of Medicine2021，15，4： | 0 |
