| 1 | Kinematics and Dynamics Hessian Matrices of Manipulators Based on Screw Theory显示文摘The complexity of the kinematics and dynamics of a manipulator makes it necessary to simplify the modeling process.However,the traditional representations cannot achieve this because of the absence of coordinate invariance.Therefore,the coordinate invariant method is an important research issue.First,the rigid-body acceleration,the time derivative of the twist,is proved to be a screw,and its physical meaning is explained.Based on the twist and the rigid-body acceleration,the acceleration of the end-effector is expressed as a linear-bilinear form,and the kinematics Hessian matrix of the manipulator(represented by Lie bracket)is deduced.Further,Newton-Euler's equation is rewritten as a linear-bilinear form,from which the dynamics Hessian matrix of a rigid body is obtained.The formulae and the dynamics Hessian matrix are proved to be coordinate invariant.Referring to the principle of virtual work,the dynamics Hessian matrix of the parallel manipulator is gotten and the detailed dynamic model is derived.An index of dynamical coupling based on dynamics Hessian matrix is presented.In the end,a foldable parallel manipulator is taken as an example to validate the deduced kinematics and dynamics formulae.The screw theory based method can simplify the kinematics and dynamics of a manipulator,also the corresponding dynamics Hessian matrix can be used to evaluate the dynamical coupling of a manipulator. | ZHAO Tieshi GENG Mingchao CHEN Yuhang LI Erwei YANG Jiantao | 2015 | Chinese Journal of Mechanical Engineering2015，28，2： | 22 |

| 3 | Comparison of breast-conserving surgery and mastectomy in early breast cancer using observational data revisited:a propensity score-matched analysis显示文摘Recent observational studies showed that breast-conserving surgery(BCS) resulted in superior survival compared to mastectomy in breast cancer patients. This study compared the clinical outcomes of BCS and mastectomy using propensity score(PS)matching analysis, which had advantages over conventional methods in reducing bias. Nonmetastatic breast cancer patients who underwent BCS and mastectomy were matched 1:1 based on their PS. We used the Kaplan-Meier method and Cox-regression model to estimate the treatment effects. A total of 2,866 patients with a median follow-up time of 67 months were included in the original study population. Although the mastectomy cohort(N=1,219) had more advanced disease compared to the BCS cohort(N=1,647), LRFS was similar between the two groups(93.8% vs. 92.4%, P>0.05). BCS(vs. mastectomy) was associated with improved DFS(73.8% vs. 58.7%, P<0.01) and CSS(91% vs. 78.2%, P<0.01) in the original population. In the PS-matched population(N=1,668), clinicopathological features were equally distributed between the two cohorts. BCS(vs. mastectomy) was not associated with improved DFS(70.7% vs. 66.9%, P>0.05) or CSS(87.5% vs. 84.9%, P>0.05). We found that PS methods reduce bias when estimating treatment effects using observational data. BCS and mastectomy show equivalent outcomes in nonmetastatic breast cancer patients. | Kai Chen Zihao Pan Liling Zhu Tingting Hu Min Peng Weijuan Jia Fengxi Su Shunrong Li Erwei Song | 2018 | Science China(Life Sciences)2018，61，12： | 12 |

| 5 | Challenges and strategies for next-generation bispecific antibody-based antitumor therapeutics显示文摘Bispecific antibodies(bsAbs)refer to a large family of molecules that recognize two different epitopes or antigens.Although a series of challenges,especially immunogenicity and chain mispairing issues,once hindered the development of bsAbs,they have been gradually overcome with the help of rapidly developing technologies in the past 5 decades.In the meantime,an increasing number of bsAb platforms have been designed to satisfy different clinical demands.Currently,numerous preclinical and clinical trials are underway,portraying a promising future for bsAb-based cancer treatment.Nevertheless,bsAb drugs still face enormous challenges in their application as cancer therapeutics,including tumor heterogeneity and mutational burden,intractable tumor microenvironment(TME),insufficient costimulatory signals to activate T cells,the necessity for continuous injection,fatal systemic side effects,and off-target toxicities to adjacent normal cells.Therefore,we provide several strategies as solutions to these issues,which comprise generating multispecific bsAbs,discovering neoantigens,combining bsAbs with other anticancer therapies,exploiting natural killer(NK)-cell-based bsAbs and producing bsAbs in situ.In this review,we mainly discuss previous and current challenges in bsAb development and underscore corresponding strategies,with a brief introduction of several typical bsAb formats. | Heliang Li Phei Er Saw Erwei Song | 2020 | Cellular & Molecular Immunology2020，17，5： | 6 |

Therefore, the burden of breast cancer in China is gradually increasing. According to figures released by the Chinese Cancer Center in 2018, the number of newly diagnostic breast cancer is about 278,900 cases, accounting for 16.51%of all women who were diagnosed with the first primary malignant tumors;and 66,000 cases of breast cancer died in 2014 (Chen et al., 2016). | Yaping Yang Jieqiong Liu Min Peng Fengxi Su Xiaoming Xie Zhenzhen Liu Jundong Wu Wei Wei Dongxian Zhou Weiwen Li Ailing Zhang Guosen Su Weixiong Yang Jishang Chen Dekui Ma Yongguang Cai Kai Chen Liling Zhu Qiang Liu Erwei Song | 2020 | Science China(Life Sciences)2020，63，9： | 4 |
| 9 | Density functional theory(DFT) studies of vanadium-titanium based selective catalytic reduction(SCR) catalysts显示文摘Based on density functional theory(DFT)and basic structure models,the chemical reactions on the surface of vanadium-titanium based selective catalytic reduction(SCR)denitrification catalysts were summarized.Reasonable structural models(non-periodic and periodic structural models)are the basis of density functional calculations.A periodic structure model was more appropriate to represent the catalyst surface,and its theoretical calculation results were more comparable with the experimental results than a nonperiodic model.It is generally believed that the SCR mechanism where NH3 and NO react to produce N2 and H2 O follows an Eley-Rideal type mechanism.NH2 NO was found to be an important intermediate in the SCR reaction,with multiple production routes.Simultaneously,the effects of H2 O,SO2 and metal on SCR catalysts were also summarized. | Ziwei Zhao Erwei Li Yu Qin Xiaolong Liu Yang Zou Heng Wu Tingyu Zhu | 2020 | Journal of Environmental Sciences2020，32，4： | 4 |
| 10 | In pursuit of a flawless aphrodite:paving the way to scarless oncoplastic breast surgery显示文摘Introduction Breast cancer is the most commonly diagnosed malig-nancy in women worldwide[1,2]and in the twentieth century,mastectomy was the primary surgical treatment for breast cancer patients.Advances in breast-conserving surgery(BCS)propelled a change in treatment rational from“maximum tolerable”to“minimum effective”ther-apy.Oncoplastic breast surgery aims to restore the shape of the breast and has been widely adopted since the past decade.Although the cosmetic outcome has been sig-nificantly improved,the scar remaining on the surgeried breast skin is still a major pitfall that urges urgent consid-eration.In this editorial,we review a series of techniques that can be incorporated in oncoplastic breast surgery to minimize scarring,signifying the beginning of an era for scarless oncoplastic surgery. | Liling Zhu Shunrong Li Luyuan Tan Xiaolan Zhang Jiannan Wu Fengxi Su Kai Chen Erwei Song | 2019 | Cancer Communications2019，39，1： | 4 |

| 13 | Treatment of autosomal recessive hearing loss via in vivo CRISPR/Cas9-mediated optimized homology-directed repair in mice显示文摘Dear Editor,Hearing loss is the most common sensory disorder in the world.Among cases of non-syndromic hearing loss,which account for 70%of all cases of genetic hearing loss,around 80%of cases arise from autosomal recessive loss-of-function mutations that require repair,rather than disruption,of the mutant allele.1 CRISPR/Cas9-mediated homology-directed repair(HDR)-based therapies have the potential to cure many genetic diseases because this class of therapeutics can achieve arbitrary base changes as well as the insertion or deletion of DNA fragments/However. | Xi Gu Xinde Hu Daqi Wang Zhijiao Xu Fang Wang Di Li Geng-lin Li Hui Yang Huawei Li Erwei Zuo Yilai Shu | 2022 | Cell Research2022，32，7： | 3 |
| 14 | A 10-miRNA risk score-based prediction model for pathological complete response to neoadjuvant chemotherapy in hormone receptor-positive breast cancer显示文摘Patients with hormone receptor(HR)-positive tumors breast cancer usually experience a relatively low pathological complete response(p CR)to neoadjuvant chemotherapy(NAC).Here,we derived a 10-micro RNA risk score(10-mi RNA RS)-based model with better performance in the prediction of p CR and validated its relation with the disease-free survival(DFS)in 755 HRpositive breast cancer patients(273,265,and 217 in the training,internal,and external validation sets,respectively).This model,presented as a nomogram,included four parameters:the 10-mi RNA RS found in our previous study,progesterone receptor(PR),human epidermal growth factor receptor 2(HER2)status,and volume transfer constant(K).Favorable calibration and discrimination of 10-mi RNA RS-based model with areas under the curve(AUC)of 0.865,0.811,and 0.804 were shown in the training,internal,and external validation sets,respectively.Patients who have higher nomogram score(>92.2)with NAC treatment would have longer DFS(hazard ratio=0.57;95%CI:0.39–0.83;P=0.004).In summary,our data showed the 10-mi RNA RS-based model could precisely identify more patients who can attain p CR to NAC,which may help clinicians formulate the personalized initial treatment strategy and consequently achieves better clinical prognosis for patients with HRpositive breast cancer. | Chang Gong Ziliang Cheng Yaping Yang Jun Shen Yingying Zhu Li Ling Wanyi Lin Zhigang Yu Zhihua Li Weige Tan Chushan Zheng Wenbo Zheng Jiajie Zhong Xiang Zhang Yunjie Zeng Qiang Liu RStephanie Huang Andrzej LKomorowski Eddy SYang François Bertucci Francesco Ricci Armando Orlandi Gianluca Franceschini Kazuaki Takabe Suzanne Klimberg Naohiro Ishii Angela Toss Mona PTan Mathew A Cherian Erwei Song | 2022 | Science China(Life Sciences)2022，65，11： | 3 |

| 16 | A novel kind of multiple steady states characteristics in the dividing wall column显示文摘In this article, one kind of multiple steady states(MSS) phenomenon was investigated for a dividing wall column(DWC). The four-section model constructed in Aspen Plus was employed to simulate two DWC cases: mixture of n-hexane, n-heptane and n-octane;system of methanol, ethanol and n-propanol. It can be seen that there is a range of vapor split ratio in which multiple solutions of reflux ratio exist for fixed DWC configuration with the same feed and product streams. The width and the curve shapes of the MSS region, and the number of solutions change with the liquid split ratio. This MSS phenomenon was further explained using the component recovery around the prefractionator and the component recycling flow inside the DWC. This MSS phenomenon is helpful for DWC design by knowing the probable existence of multiple solutions in advance. | Erwei Song Zengxi Li Erqiang Wang | 2019 | Chinese Journal of Chemical Engineering2019，27，4： | 2 |
| 17 | Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups显示文摘Zedoary tumeric(Curcumae Rhizoma,Ezhu in Chinese)has a long history of application and has great potential in the treatment of liver cancer.The antiliver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances.In order to clarify the specific mechanism of zedoary tumeric against liver cancer,this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer,and then verifies the joint anti liver cancer mechanism of its“pharmacodynamic group”.By searching the research on the antihepatoma effect of active components of zedoary tumeric in recent years,we found that pharmacodynamic substances,including curcumol,zedoarondiol,curcumenol,curzerenone,curdione,curcumin,germacrone,β-elemene,can act on multi-target and multi-channel to play an antihepatoma role.For example,curcumin can regulate miR,GLO1,CD133,VEGF,YAP,LIN28B,GPR81,HCAR-1,P53 and PI3K/Akt/mTOR,HSP70/TLR4 and NF-κB.Wnt/TGF/EMT,Nrf2/Keap1,JAK/STAT and other pathways play an antihepatoma role.Network pharmacological analysis showed that the core targets of the“pharmacodynamic group”for anti-life cancer are AKT1,EGFR,MAPK8,etc,and the core pathways are neuroactive live receiver interaction,nitrogen metabolism,HIF-1 signaling pathway,etc.At the same time,by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and“pharmacodynamic group”,it is found that they have great reference significance in target,pathway,biological function,determination of core pharmacodynamic components,formation of core target protein interaction,in-depth research of single pharmacodynamic substance,increasing curative effect and so on.By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and“pharmacodynamic group”in the treatment of liver cancer,this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and“pharmacodynamic group”. | Zeyu Li Erwei Hao Rui Cao Si Lin Linghui Zou Tianyan Huang Zhengcai Du Xiaotao Hou Jiagang Deng | 2022 | Chinese Herbal Medicines2022，14，4： | 2 |
| 18 | Uncovering the mysterious identity of Taisui——an old Chinese folk legend显示文摘Dear Editor,Taisui(太岁) has attracted great attention in China because it has been described in ancient Chinese texts as an entity possessing mysterious properties. In Chinese mythology and folklore, Jupiter is the God of the 'Sui'(year) and is worshiped in Daoism. Jupiter appears at the same location in the sky approximately every 12 years(Jupiter’s orbit is11.86 years). However, since each cycle of Jupiter lasts for exactly 11.86 years and one Chinese year cycle comprises exactly 12 years, after approximately 84.7 years, Jupiter travels one cycle more than the number of cycles assumed by the ancient Chinese, which is called Taisui. According to the belief of the ancient Chinese, people are alerted when Taisui is digging in the ground, foretelling the destruction of houses or occurrence of natural disasters, such as floods and earthquakes(Zhao et al., 2018). | Erwei Li Jinwei Ren Qian Chen Hanxing Zhang Bin Lin Hui Zhang Shumin Zhang Xiaoling Zhang Lei Cai Xingzhong Liu | 2020 | Science China(Life Sciences)2020，63，12： | 2 |
