| 1 | Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation. | Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu | 2019 | Cancer Biology & Medicine2019，16，1： | 14 |

| 3 | Development of a machine learning model to predict early recurrence for hepatocellular carcinoma after curative resection显示文摘Background:Early recurrence is common for hepatocellular carcinoma(HCC)after surgical resection,being the leading cause of death.Traditionally,the COX proportional hazard(CPH)models based on linearity assumption have been used to predict early recurrence,but predictive performance is limited.Machine learning models offer a novel methodology and have several advantages over CPH models.Hence,the purpose of this study was to compare random survival forests(RSF)model with CPH models in prediction of early recurrence for HCC patients after curative resection.Methods:A total of 4,758 patients undergoing curative resection from two medical centers were included.Fifteen features including age,gender,etiology,platelet count,albumin,total bilirubin,AFP,tumor size,tumor number,microvascular invasion,macrovascular invasion,Edmondson-Steiner grade,tumor capsular,satellite nodules and liver cirrhosis were used to construct the RSF model in training cohort.Discrimination,calibration,clinical usefulness and overall performance were assessed and compared with other models.Results:Five hundred survival trees were used to generate the RFS model.The five highest Variable Importance(VIMP)were tumor size,macrovascular invasion,microvascular invasion,tumor number and AFP.In training,internal and external validation cohort,the C-index of RSF model were 0.725[standard errors(SE)=0.005],0.762(SE=0.011)and 0.747(SE=0.016),respectively;the Gönen&Heller’s K of RSF model were 0.684(SE=0.005),0.711(SE=0.008)and 0.697(SE=0.014),respectively;the time-dependent AUC(2 years)of RSF model were 0.818(SE=0.008),0.823(SE=0.014)and 0.785(SE=0.025),respectively.The RSF model outperformed early recurrence after surgery for liver tumor(ERASL)model,Korean model,American Joint Committee on Cancer tumor-node-metastasis(AJCC TNM)stage,Barcelona Clinic Liver Cancer(BCLC)stage and Chinese stage.The RSF model is capable of stratifying patients into three different risk groups(low-risk,intermediate-risk,high-risk groups)in the training and two validation cohorts(all P<0.0001).A web-based prediction tool was built to facilitate clinical application(http://gffzz8caf4f582aa3478esf5qkfuqqb9kq66kk.ffgz.tsg.suse.edu.cn/surgery_predict/).Conclusions:The RSF model is a reliable tool to predict early recurrence for patients with HCC after curative resection because it exhibited superior performance compared with other models.This novel model will be helpful to guide postoperative follow-up and adjuvant therapy. | Jianxing Zeng Jinhua Zeng Kongying Lin Haitao Lin Qionglan Wu Pengfei Guo Weiping Zhou Jingfeng Liu | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 6 |
| 4 | IMF production and symmetry energy in heavy ion collisions near Fermi energy显示文摘The symmetry energy at the time of the production of intermediate mass fragments(IMFs) is studied using experimentally observed IMF multiplicities combined with quantum statistical model calculations(QSM of Hahn and St cker).The ratios of difference in chemical potentials between neutrons and protons relative to the temperature,(μn-μp)/T,and the double ratio temperature,T,were extracted experimentally in the reactions of64,70Zn,64Ni+58,64Ni,112,124Sn,197Au,232Th at 40A MeV.The extracted(μn-μp)/TTscales linearly with δNN,where δNN is the asymmetry parameter,(N-Z)/A,of the emitting source and(μn-μp)/T=(11.1 1.4)δNN0.21 was derived.The experimentally extracted(μn-μp)/T and the double ratio temperatures are compared with those from the QSM calculations.The temperatures-,T,and densities,ρ,extracted from the(μn-μp)/T values agreed with those from the double ratio thermometer which used the yield ratios of d,t,h and α particles.However the two analyses of the differential chemical potential analysis and the initial temperature analysis end up almost identical relation between T and ρ.T=5.25±0.75 MeV is evaluated from the(μn-μp)/Tanalysis,but no density determination was possible.From the extracted T value,the symmetry energy coefficient Esym =14.6±3.5 MeV is determined for the emitting source of T=5.25±0.75 MeV. | WADA Roy HUANG Meirong LIN Weiping LIU Xingquan ZHAO Minghui CHEN Zhiqiang | 2013 | Nuclear Science and Techniques2013，24，5： | 5 |
| 5 | SCStore: Managing Scientific Computing Packages for Hybrid System with Containers显示文摘Managing software packages in a scientific computing environment is a challenging task, especially in the case of heterogeneous systems. It is error prone when installing and updating software packages in a sophisticated computing environment. Testing and performance evaluation in an on-the-fly manner is also a troublesome task for a production system. In this paper, we discuss a package management scheme based on containers. The newly developed method can ease the maintenance complexity and reduce human mistakes. We can benefit from the self-containing and isolation features of container technologies for maintaining the software packages among intricately connected clusters. By deploying the Super Computing application Strore(SCStore) over the WAN connected world-largest clusters, it proved that it can greatly reduce the effort for maintaining the consistency of software environment and bring benefit to achieve automation. | Wusheng Zhang Jiao Lin Weiping Xu Haohuan Fu Guangwen Yang | 2017 | Tsinghua Science and Technology2017，22，6： | 5 |

| 7 | Prognostic value of interim ^(18)F-FDG PET/CT in diffuse large B-cell lymphoma显示文摘Objective: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease. The prognostic factor currently used is not accurate enough to predict the outcomes of patients with DLBCL. The prognostic significance of interim PET/CT in DLBCL remains controversial. The aim of this study is to determine the predictive value of interim 18F-FDG PET/CT after first-line treatment in patients with DLBCL. Methods: Thirty-two patients with DLBCL underwent baseline, interim and post-treatment 18F-FDG PET/CT scans. Imaging results were analyzed for the survival of patients via software SPSS 13.0, retrospectively. Results: Thirty-one of the 32 patients were treated with R-CHOP regimen, and interim 18F-FDG PET/CT of 24 patients was performed after 2 cycles of treatment. After a median follow-up period of 16.7 months, the 2-year progression-free survival (PFS) rates were significantly different between the groups above and below SUV max cut-off value of 2.5 (P=0.039). No significant differences were found in the 2-year PFS rates if SUV max cut-off values were set as 2.0 and 3.0, respectively (P=0.360; P=0.113). Conclusions: Interim PET/CT could predict the prognosis of DLBCL patients with the SUV max cut-off value of 2.5, but more clinical data should be concluded to confirm this conclusion. | Zhitao Ying Xuejuan Wang Yuqin Song Wen Zheng Xiaopei Wang Yan Xie Ningjing Lin Meifeng Tu Lingyan Ping Weiping Liu Lijuan Deng Chen Zhang Zhi Yang Jun Zhu | 2013 | Chinese Journal of Cancer Research2013，25，1： | 4 |
| 8 | Prognostic value of pre-and post-transplantation 18F-fluorodeoxyglucose positron emission tomography results in non-Hodgkin lymphoma patients receiving autologous stem cell transplantation显示文摘Objective: High-dose chemotherapy(HDC) followed by autologous stem cell transplantation(ASCT) is the standard of care in the upfront or relapsed/refractory setting in some patients with non-Hodgkin lymphoma(NHL).However,a proportion of patients do not respond to ASCT.^(18)F-fluorodeoxyglucose(FDG) positron emission tomography(PET)/computed tomography(CT) has been widely used for staging,response evaluation,and prognosis prediction.Here,we investigated the prognostic role of PET/CT in NHL patients before and after ASCT.Methods: A retrospective study was conducted at Peking University Cancer Hospital.All NHL patients who underwent ASCT between March 2010 and July 2016 were identified.Patients who had PET/CT scan before and after ASCT were included.Deauville criteria(5-point scale) were used to interpret PET scans.Univariate and multivariate survival analyses were performed using Cox regression.The predictive value of PET scanning was estimated by comparing the area under the receiver operating characteristic(ROC) curve.Results: In total,79 patients were enrolled in this study.In univariate analysis,pre-and post-ASCT PET result was identified as prognostic factors for 3-year progression-free survival(PFS) and overall survival(OS).Patients with negative pre-ASCT PET result demonstrated significantly better PFS(84.2% vs.54.2%) and OS(89.2% vs.63.6%) than patients with positive pre-ASCT PET result.PFS(91.6% vs.25.3%) and OS(96.5% vs.36.8%) were also significantly different between patients with negative and positive post-ASCT PET result.Multivariate analysis also showed a significant association between survival and post-ASCT PET result.ROC analysis revealed that the predictive value of post-ASCT PET result was superior to that of pre-ASCT PET result alone.Combined pre-and post-ASCT PET result is better for predicting outcomes in patients with NHL receiving transplantation.Deauville criteria score >3 was identified as the best cutoff value for post-ASCT PET.Conclusions: Post-ASCT PET result was more important than pre-ASCT PET result in predicting outcomes for NHL patients who underwent ASCT.The prognostic significance can be improved when combining preASCT PET result with post-ASCT PET result.Deauville criteria can be used for interpreting PET scans in this scenario. | Zhitao Ying Lan Mi Xuejuan Wang Yuewei Zhang Zhi Yang Yuqin Song Xiaopei Wang WenZheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Chen Zhang Weiping Liu LijuanDeng Jun Zhu | 2017 | Chinese Journal of Cancer Research2017，29，6： | 3 |

| 10 | Bone marrow and the control of immunity显示文摘Bone marrow is thought to be a primary hematopoietic organ. However, accumulated evidences demonstrate that active function and trafficking of immune cells, including regulatory T cells, conventional T cells, B cells, dendritic cells, natural killer T (NKT) cells, neutrophils, myeloid-derived suppressor cells and mesenchymal stem cells, are observed in the bone marrow. Furthermore, bone marrow is a predetermined metastatic location for multiple human tumors. In this review, we discuss the immune network in the bone marrow. We suggest that bone marrow is an immune regulatory organ capable of fine tuning immunity and may be a potential therapeutic target for immunotherapy and immune vaccination. | Ende Zhao Huanbin Xu Lin Wang Ilona Kryczek Ke Wu Yu Hu Guobin Wang Weiping Zou | 2012 | Cellular & Molecular Immunology2012，9，1： | 3 |

| 12 | Parametrization of woods-saxon potential for heavy-ion systems显示文摘Several elastic scattering angular distributions of ^(12)C from target nuclei of A ≥39 are analyzed to extract the Woods-Saxon potential parameters with the fixed imaginary potential and Coulomb radius parameters.Using the best fitted diffuseness parameters,the correlations of the real part parameters with A_1^(1/3)+ A_2^(1/3) and incident energy are revealed, and the systematic Woods-Saxon potential parameters are presented for nucleus-nucleus interaction.The proposed potential parameters can reproduce not only the elastic scattering angular distributions induced by ^(12)C,but also many elastic scattering angular distributions induced by the projectiles other than ^(12)C,thus providing important inputs for the study of nuclear reactions of heavy-ion systems. | Lin Gan ZhiHong Li HuiBin Sun DanYang Pang Bing Guo YunJu Li Jun Su ShengQuan Yan ErTao Li YouBao Wang Gang Lian ZhiYu Han XinYue Li DongHui Li TianLi Ma ChangJin Pei YangPing Shen Yi Su Sheng Zeng Yong Zhou WeiPing Liu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，8： | 2 |

| 14 | Tet2 Regulates Osteoclast Differentiation by Interacting with Runx1 and Maintaining Genomic 5-Hydroxymethylcytosine(5hmC)显示文摘As a dioxygenase, Ten-Eleven Translocation 2(TET2) catalyzes subsequent steps of 5-methylcytosine(5 mC) oxidation. TET2 plays a critical role in the self-renewal, proliferation,and differentiation of hematopoietic stem cells, but its impact on mature hematopoietic cells is not well-characterized. Here we show that Tet2 plays an essential role in osteoclastogenesis. Deletion of Tet2 impairs the differentiation of osteoclast precursor cells(macrophages) and their maturation into bone-resorbing osteoclasts in vitro. Furthermore, Tet2^(-/-) mice exhibit mild osteopetrosis, accompanied by decreased number of osteoclasts in vivo. Tet2 loss in macrophages results in the altered expression of a set of genes implicated in osteoclast differentiation, such as Cebpa, Mafb, and Nfkbiz. Tet2 deletion also leads to a genome-wide alteration in the level of 5-hydroxymethylcytosine(5 hmC) and altered expression of a specific subset of macrophage genes associated with osteoclast differentiation. Furthermore, Tet2 interacts with Runx1 and negatively modulates its transcriptional activity. Our studies demonstrate a novel molecular mechanism controlling osteoclast differentiation and function by Tet2, that is, through interactions with Runx1 and the maintenance of genomic 5 hmC. Targeting Tet2 and its pathway could be a potential therapeutic strategy for the prevention and treatment of abnormal bone mass caused by the deregulation of osteoclast activities. | Yajing Chu Zhigang Zhao David Wayne Sant Ganqian Zhu Sarah M.

| 15 | PEG-asparaginase in BFM-90 regimen improves outcomes in adults with newly diagnosed lymphoblastic lymphoma显示文摘Objective: Although L-asparaginase(L-ASP) is a standard treatment for lymphoblastic lymphoma(LBL),hypersensitivity reactions by some patients limit its application. Polyethylene glycol-conjugated asparaginase(PEGASP) has a lower immunogenicity and is a standard treatment in all pediatric acute lymphoblastic leukemia(ALL).In this study, we investigated the efficacy and toxicity of PEG-ASP instead of L-ASP as used in the BFM-90regimen(PEG-ASP-BFM-90) for adult LBL.Methods: Between June 2012 and July 2015, we treated 30 adult patients with newly diagnosed LBL, using PEGASP-BFM-90 in a prospective, multicenter and single-arm clinical study at 5 participating institutions in China.Results: All the 30 patients, including 19 males and 11 females with a median age of 30(range: 18–62) years,completed 128 times of the PEG-ASP, with the median of 4(range: 2–6) times. Patients did not receive radiotherapy at this time. The overall response rate was 86.7%(26/30), with 50.0%(15/30) complete response and36.7%(11/30) partial response. The 3-year overall survival was 46.0% [95% confidence interval(95% CI),28.2%–64.8%], and the 3-year progression-free survival was 43.0%(95% CI, 25.7%–62.0%). Major adverse events were myelosuppression, reduced fibrinogen, liver dysfunction and digestive tract toxicities. No allergic reaction and no treatment-related mortality or severe complications were recorded.Conclusions: Our clinical data and observed outcomes indicate that 1 dose of PEG-ASP can replace multiple doses of native L-ASP in BFM-90, with predominantly grade 3–4 neutropenia for adult LBL, and no therapyrelated deaths. The effect is similar to previous reports of PEG-ASP-containing regimens for adult ALL. Major advantages include less serious allergic reactions, 2–3 weeks of action duration, and convenience for patients and physicians. | Wen Zheng Hanyun Ren Xiaoyan Ke Mei Xue Yongqing Zhang Yan Xie Ningjing Lin Meifeng Tu Weiping Liu Lingyan Ping Zhitao Ying Chen Zhang Lijuan Deng Xiaopei Wang Yuqin Song Jun Zhu | 2017 | Chinese Journal of Cancer Research2017，29，1： | 2 |
| 16 | Impact of pathological response after preoperative transcatheter arterial chemoembolization(TACE)on incidences of microvascular invasion and early tumor recurrence in hepatocellular carcinoma:a multicenter propensity score matching analysis显示文摘Background:To study the influence of pathological responses(PR)after transcatheter arterial chemoembolization(TACE)on incidences of microvascular invasion(MVI)and early recurrence in hepatocellular carcinoma(HCC)patients.Methods:Between 2013 to 2015,consecutive HCC patients who underwent liver resection with“curative”intent at three hospitals were enrolled in this study.Patients with different areas of PR after preoperative TACE were compared with those without preoperative TACE on the incidences of MVI,early recurrence rates and patterns of recurrence before and after propensity score matching(PSM).Results:Of 1,970 patients,737 patients who received preoperative TACE were divided into three groups according to the areas of PR:≥90%(n=226),60-90%(n=447),and<60%(n=64).PR≥90%was an independent protective factor of incidences of MVI[odds ratio(OR),0.144;95%confidence interval(CI),0.082-0.245,P<0.001)and early recurrence(HR,0.742;95%CI,0.561-0.963,P=0.032);while PR<60%was an independent risk factor of incidences of MVI(OR,6.076;95%CI,3.004-11.728,P<0.001)and early recurrence(HR,1.428;95%CI,1.095-1.929;P=0.009).Furthermore,patients with PR<60%were significantly more likely to develop multiple intrahepatic recurrences involving multiple hepatic segments when compared with patients without preoperative TACE.Conclusions:This study indicated the area of PR after TACE was closely associated with the incidences of MVI and early tumor recurrence.Patients with PR<60%were at significantly higher risks of having more MVI,early and multiple tumor recurrences. | Yun Yang Zheng Dang Peng Lu Youwen Qian Kongying Lin Zeya Pan Wan Yee Lau Weiping Zhou | 2022 | Hepatobiliary Surgery and Nutrition2022，11，3： | 2 |
| 17 | Nonlinear Prediction with Deep Recurrent Neural Networks for Non-Blind Audio Bandwidth Extension显示文摘Non-blind audio bandwidth extension is a standard technique within contemporary audio codecs to efficiently code audio signals at low bitrates. In existing methods, in most cases high frequencies signal is usually generated by a duplication of the corresponding low frequencies and some parameters of high frequencies. However, the perception quality of coding will significantly degrade if the correlation between high frequencies and low frequencies becomes weak. In this paper, we quantitatively analyse the correlation via computing mutual information value. The analysis results show the correlation also exists in low frequency signal of the context dependent frames besides the current frame. In order to improve the perception quality of coding, we propose a novel method of high frequency coarse spectrum generation to improve the conventional replication method. In the proposed method, the coarse high frequency spectrums are generated by a nonlinear mapping model using deep recurrent neural network. The experiments confirm that the proposed method shows better performance than the reference methods. | Lin Jiang Ruimin Hu Xiaochen Wang Weiping Tu Maosheng Zhang | 2018 | China Communications2018，15，1： | 2 |
| 18 | A durable 4-1BB-based CD19 CAR-T cell for treatment of relapsed or refractory non-Hodgkin lymphoma显示文摘Objective:Previous studies reported that 4-1BB-based CD19 chimeric antigen receptor(CAR)-T cells were more beneficial for the clinical outcomes than CD28-based CAR-T cells,especially the lower incidence rate of severe adverse events.However,the median progression-free survival(mPFS)of 4-1BB-based product Kymriah was shorter than that of CD28-based Yescarta(2.9 months vs.5.9 months),suggesting that Kymriah was limited in the long-term efficacy.Thus,a safe and durable 4-1BB-based CD19 CAR-T needs to be developed.Methods:We designed a CD19-targeted CAR-T(named as IM19)which consisted of an FMC63 scFv,4-1BB and CD3ζintracellular domain and was manufactured into a memory T-enriched formulation.A phase I/II clinical trial was launched to evaluate the clinical outcomes of IM19 in relapsed or refractory(r/r)B cell non-Hodgkin lymphoma(B-NHL).Dose-escalation investigation(at a dose of 5×10^(5)/kg,1×10^(6)/kg and 3×106/kg)was performed in 22 r/r B-NHL patients.All patients received a single infusion of IM19 after 3-day conditional regimen.Results:At month 3,the overall response rate(ORR)was 59.1%,the complete response rate(CRR)was 50.0%.The mPFS was 6 months and the 1-year overall survival rate was 77.8%.Cytokine release syndrome(CRS)occurred in 13 patients(59.1%),with 54.5%of grade 1−2 CRS.Only one patient(4.5%)experienced grade 3 CRS and grade 3 neurotoxicity.Conclusions:These results demonstrated the safety and durable efficacy of a 4-1BB-based CD19 CAR-T,IM19,which is promising for further development and clinical investigation. | Zhitao Ying Ting He Shanzhao Jin Xiaopei Wang Wen Zheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Weiping Liu Lijuan Deng Yanping Ding Xuelian Hu Bing Bu Xin’an Lu Yuqin Song Jun Zhu | 2022 | Chinese Journal of Cancer Research2022，34，1： | 2 |
