1Clinical features and outcomes of diffuse large B-cell lymphoma based on nodal or extranodal primary sites of origin:Analysis of 1,085 WHO classified cases in a single institution in China显示文摘Objective: To explore the clinicobiologic features and outcomes of diffuse large B-cell lymphoma(DLBCL)patients in China according to the primary site.Methods: A total of 1,085 patients diagnosed with DLBCL in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during a 6-year period were enrolled. Their clinical characteristics and outcomes were analyzed according to the primary site.Results: In the 1,085 patients, 679(62.6%) cases were nodal DLBCL(N-DLBCL) and 406 cases(37.4%) were extranodal DLBCL(EN-DLBCL). The most common sites of N-DLBCL were lymphonodus(64.8%), Waldeyer's ring(19.7%), mediastinum(12.8%) and spleen(2.7%), while in EN-DLBCL, stomach(22.4%), intestine(16.0%),nose and sinuses(8.9%), testis(8.4%), skin(7.9%), thyroid(6.9%), central nervous system(CNS)(6.4%), breast(5.7%), bone(3.4%), and salivary gland(2.7%) were most common. N-DLBCL patients tend to present B symptoms, bulky disease, and elevated LDH more often, while age >60 years, extranodal sites >1, Ann Arbor stage I or II, bone marrow involvement, and Ki-67 index >90% were usually seen in EN-DLBCL. The 5-year overall survival(OS) rate and progression-free survival(PFS) rate for all patients were 62.5% and 54.2%. The 5-year OS rate for patients with N-DLBCL and EN-DLBCL were 65.5% and 56.9%(P=0.008), and the 5-year PFS were57.0% and 49.0%(P=0.020). Waldeyer's ring originated DLBCL possessed the highest 5-year OS rate(83.6%) and PFS rate(76.9%) in N-DLBCL. The top five EN-DLBCL subtypes with favorable prognosis were stomach,breast, nose and sinuses, lung, salivary gland, with 5-year OS rate: 70.3%, 69.6%, 69.4%, 66.7% and 63.6%,respectively. While CNS, testis, oral cavity and kidney originated EN-DLBCL faced miserable prognosis, with 5-year OS rate of 26.9%, 38.2%, and 42.9%.Conclusions: In our study, primary sites were associated with clinical characteristics and outcomes. Compared with EN-DLBCL, N-DLBCL had better prognosis.Yuankai Shi Ying Han Jianliang Yang Peng Liu Xiaohui He Changgong Zhang Shengyu Zhou Liqiang Zhou Yan Qin Yongwen Song Yueping Liu Shulian Wang Jing Jin Lin Gui Yan Sun 2019Chinese Journal of Cancer Research2019,31,1:19
2Application 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 2019Cancer Biology & Medicine2019,16,1:14

4PD-L1 is a direct target of cancer-FOXP3 in pancreatic ductal adenocarcinoma(PDAC),and combined immunotherapy with antibodies against PD-L1 and CCL5 is effective in the treatment of PDAC显示文摘High expression of PD-L1 marks the poor prognosis of pancreatic ductal adenocarcinomas(PDAC).However,the regulatory mechanism of PD-L1 remains elusive.We recently reported that cancer Forkhead box protein 3(Cancer-FOXP3 or C-FOXP3)promoted immune evasion of PDAC by recruiting Treg cells into PDAC via upregulation of CCL5.In this study,we confirmed that PD-L1 was overexpressed in PDAC samples from two independent cohorts of patients with radical resection.Moreover,C-FOXP3 was colocalized and correlated with the expression of PD-L1 in tumor cells at the mRNA and protein levels,and this finding was confirmed by the The Cancer Genome Atlas(TCGA)database.Chromatin immunoprecipitation(ChIP)revealed that C-FOXP3 directly bound to the promoter region of PD-L1 in pancreatic cancer cells.Furthermore,overexpression of C-FOXP3 activated the luciferase reporter gene under the control of the PD-L1 promoter.However,mutation of the binding motif-a completely reversed the luciferase activity.In addition,C-FOXP3-induced upregulation of PD-L1 effectively inhibited the activity of CD8+T cells.Based on our recent finding that the CCL-5 antibody achieved a better response to PDAC models with high C-FOXP3 levels,we further demonstrated that the PD-L1 antibody strengthened the antitumor effect of CCL-5 blockade in xenograft and orthotopic mouse models with high C-FOXP3 levels.In conclusion,C-FOXP3 directly activates PD-L1 and represents a core transcription factor that mediates the immune escape of PDAC.Combined blockade of PD-L1 and CCL-5 may provide an effective therapy for patients with PDAC that have high C-FOXP3 levels.Xiuchao Wang Xin Li Xunbin Wei Haiping Jiang Chungen Lan Shengyu Yang Han Wang Yanhui Yang Caijuan Tian Zanmei Xu Jiangyan Zhang Jihui Hao He Ren 2020Signal Transduction and Targeted Therapy2020,5,1:11
5Autologous hematopoietic stem cell transplantation in chemotherapy-sensitive lymphoblastic lymphoma: treatment outcome and prognostic factor analysis显示文摘Objective: The study evaluated the effectiveness of autologous hematopoietic stem cell transplantation(AHSCT) in the treatment of lymphoblastic lymphoma(LL).Methods: We retrospectively analyzed the data from 41 patients with chemotherapy-sensitive LL who underwent hematopoietic stem cell transplantation(HSCT) from December 1989 to December 2009 in a single institution.Results: HSCT was conducted as first-line consolidation therapy and salvage therapy in 36 and 5 patients, respectively. The median follow-up was 97.1 months(range, 24.6-173.1 months). The 5-year overall survival(OS) and event-free survival(EFS) rate were 64% and 47% for the initially treated patients, respectively, and were both 20% for the relapsed ones. Bone marrow(BM) involvement and chemotherapy cycles prior to transplantation were identified as significant prognostic factors for EFS in multivariate analysis.Conclusions: These results confirm that AHSCT is a reasonable option for chemotherapy-sensitive LL patients in first complete remission(CR1).Youwu Shi Shengyu Zhou Xiaohui He Xiaohong Han Shikai Wu Feng Pan Peng Liu Yinyu Liu Yingheng Lei Hongzhi Zhang Jianliang Yang Yan Qin Changgong Zhang Sheng Yang Liya Zhao Kehuan Luo Guanqing Wu Yan Sun Yuankai Shi 2015Chinese Journal of Cancer Research2015,27,1:9
6A wearable noncontact free-rotating hybrid nanogenerator for self-powered electronics显示文摘Self-powerability is a new trend in the development of portable devices.Harvesting biomechanical energy to power personal information electronics is of great significance.In this work,we report a wearable noncontact freerotating hybrid nanogenerator(WRG),which is constituted by a triboelectric nanogenerator and an electromagnetic generator.A continuous output over 2 seconds can be achieved during one instantaneous incentive by external force,which is improved by two orders of magnitude compared to other wearable nanogenerators due to its unique mechanical energy storage design.The WRG can be integrated into shoes to generate an output energy of 14.68 mJ in each stepping,which meets the power requirements of most personal information electronics.The wireless sensor,GPS,and smartphone can be powered by the WRG continuously.The WRG is expected to be applied in self-powered information electronics extensively in the future.Dongjie Jiang Han Ouyang Bojing Shi Yang Zou Puchuan Tan Xuecheng Qu Shengyu Chao Yuan Xi Chaochao Zhao Yubo Fan Zhou Li 2020InfoMat2020,2,6:8
7Clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma显示文摘Objective: To assess the clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma(DLBCL).Methods: A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed.Results: During a median follow-up period of 39.8 months(5.4-93.0 months), the median progression-free survival(PFS) was 26.2 months(95% CI: 0-65 months) and the 3-year overall survival(OS) rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage(stage I/II), lactate dehydrogenase(LDH) ≤245 U/L, international prognostic index(IPI) ≤1, primary tumor diameter <7.5 cm, and patients who had complete response(CR) and received doxorubicin-contained chemotherapy(P<0.05). There was a trend toward superior outcome for patients who received combined therapy(surgery/chemotherapy/radiotherapy)(P=0.055). Patients who had CR, primary tumor diameter <7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis.Conclusions: Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy(RT) seemed to improve survival.Bo Jia Yuankai Shi Mei Dong Fengyi Feng Sheng Yang Hua Lin Liqiang Zhou Shengyu Zhou Shanshan Chen Jianliang Yang Peng Liu Yan Qin Changgong Zhang Lin Gui Lin Wang Xue Wang Xiaohui He 2014Chinese Journal of Cancer Research2014,26,4:5
8Preparation of lignin/TiO2 nanocomposites and their application in aqueous polyurethane coatings显示文摘A simple method using a water soluble lignin quaternary ammonium salt (LQAS) and TiO2 has been developed for the preparation of lignin/TiO2 nanocomposites in an aqueous medium under mild conditions. The LQAS/TiO2 nanocomposites contain well-dispersed small particles with excellent ultraviolet (UV) shielding abilities and good compatibilities with waterborne polyurethane (WPU). When the LQAS/TiO2 nanocomposites were blended with WPU, the UV absorbance and the tensile ductility of the WPU increased significantly. The composite WPU hybrid film containing 6 wt-% LQAS/TiO2 nanocomposite had the highest visible light transmittance and had excellent ultraviolet aging properties. After 192 h of UV light irradiation, the tensile strength of the composite film was above 8 MPa and the elongation at break was 800%. This work highlights new possibilities for the utilization of alkali lignin.Dongjie Yang Shengyu Wang Ruisheng Zhong Weifeng Liu Xueqing Qiu 2019Frontiers of Chemical Science and Engineering2019,13,1:5
9Geospatial Service Web:towards integrated cyberinfrastructure for GIScience显示文摘A geospatial cyberinfrastructure is needed to support advanced GIScience research and education activities.However,the heterogeneous and distributed nature of geospatial resources creates enormous obstacles for building a unified and interoperable geospatial cyberinfrastructure.In this paper,we propose the Geospatial Service Web(GSW)to underpin the development of a future geospatial cyberinfrastructure.The GSW excels over the traditional spatial data infrastructure by providing a highly intelligent geospatial middleware to integrate various geospatial resources through the Internet based on interoperable Web service technologies.The development of the GSW focuses on the establishment of a platform where data,information,and knowledge can be shared and exchanged in an interoperable manner.Theoretically,we describe the conceptual framework and research challenges for GSW,and then introduce our recent research toward building a GSW.A research agenda for building a GSW is also presented in the paper.GONG Jianya WU Huayi ZHANG Tong GUI Zhipeng LI Zhenlong YOU Lan SHEN Shengyu ZHENG Jie GENG Jing QI Kunlun YANG Wenjing LI Zhenqiang YU Jingmin 2012Geo-Spatial Information Science2012,15,2:5
10Autologous peripheral blood stem cell mobilization following dose-adjusted cyclophosphamide, doxorubicin, vincristine and prednisolone chemotherapy alone or in combination with rituximab in treating high-risk non-Hodgkin's lymphoma显示文摘Background: The regimen of cyclophosphamide, doxorubicin, vincristine, and prednisolone(CHOP) is an eicient treatment of non-Hodgkin's lymphoma(NHL). This study aimed to assess the eicacy and toxicity of dose-adjusted CHOP alone or in combination with rituximab(R-CHOP) by examining the stem cell mobilization in NHL patients. Factors afecting the collection of CD34+ cells were also explored.Methods: Our retrospective study included 39 patients eligible for autologous stem cell transplantation: 14 patients who expressed CD20 and were inancially eligible received R-CHOP for autologous peripheral blood stem cell(APBSC) mobilization; the remaining 25 patients received CHOP.Results: The median CD34+ cell yield was 7.01 × 106 cells/kg body weight(range 1.49–28.39 × 106 cells/kg body weight), with only two patients failing to meet the target CD34+ cell harvest of ber of apheresis procedures per patient was 1(range 1–3). The≥2.0 APBS× 106 cells/kg body weight. The median numC mobilization yield of the CHOP group appeared to be higher than that of the R-CHOP group(P response(CR) rate in = 0.005), whereas the success rate was similar between groups. R-CHOP elevated the completeB cell lymphoma patients as compared with CHOP(P = 0.01). No signiicant diferences in toxicity or engraftment were observed between the two groups.Conclusion: The present study demonstrated that dose-adjusted CHOP chemotherapy efectively mobilized APBSCs in NHL patients and that the addition of rituximab to dose-adjusted CHOP chemotherapy elevated the CR rate for patients with B-cell lymphoma.Yuankai Shi Ping Zhou Xiaohong Han Xiaohui He Shengyu Zhou Peng Liu Jianliang Yang Changgong Zhang Lin Gui Yan Qin Sheng Yang Liya Zhao Jiarui Yao Shuxiang Zhang 2015Chinese Journal of Cancer2015,34,11:4
11Dietary energy intake affects fetal survival and development during early and middle pregnancy in Large White and Meishan gilts显示文摘This experiment was designed to determine the effects of variations in dietary energy intake on reproductive performance and gene expression of luteal and endometrium tissues in Large White(LW)and Meishan(MS) gilts during early and middle pregnancy. After insemination, 32 LW gilts were assigned to high and low(HE_Land LE_L, 14.23 and 12.56 MJ DE/kg, respectively) diet treatment groups,while 32 MS gilts were allocated to HE_M and LE_M(12.56 and 10.88 MJ DE/kg) groups. Gilts were slaughtered on days 35, 55 and 90 of gestation. The fetal survival and luteal progesterone(P_4) concentration in the HE_Lgroup were higher on day 35 but lower on day 90 of gestation compared with the LE_L group(P < 0.05) for LW gilts. However, fetal survival and luteal P_4 concentration on day 35 of gestation were greater(P < 0.05) in the LE_M group than in the HE_M group for MS gilts, but no significant difference in mid-gestation was showed. The fetal weights of both breeds were higher for the high energy diets compared with the respective control group on day 90 of gestation(P < 0.05). In addition,the m RNA levels of P_4 synthesis-related proteins had correlated with luteal P_4 concentration in both breeds. Further, endometrial levels of uteroferrin(ACP5), retinol-binding protein 4(RBP_4) and secreted phosphoprotein 1(SPP1) m RNA were upregulated in the HE_Lgroup on day 35 of gestation but ACP5 and SPP1 were downregulated on day 55 of gestation compared with the LE_Lgroup(P < 0.05) for LW gilts. In MS gilts, diet only affected the expression of SPP1(P < 0.05). Our results revealed the differential sensitivity of LW and MS breeds to variations in dietary energy intake. For LW gilts, the HE_Lgroup improved fetal survival on day 35 but a sustained high energy diet decreased fetal survival on day 90 of gestation. The differences in dietary energy intake did not influence fetal survival on day 90 of gestation but the higher energy diet did increase fetal weight in the MS breed compared with the lower energy intake diet. These results may be due to differential luteal secretion activity and endometrium gene expression in these two breeds.Long Che Zhenguo Yang Mengmeng Xu Ziyun Zhang Peilin Liu Shengyu Xu Lianqiang Che Yan Lin Zhengfeng Fang Bin Feng Jian Li De Wu 2015Animal Nutrition2015,,3:4
12Overcoming Resistance to Drugs Targeting KRAS^(G12C) Mutation显示文摘Activating KRAS mutations are present in 25%of human cancer.Although oncogenic Ras was deemed“undruggable”in the past,recent efforts led to the development of pharmacological inhibitors targeting the KRAS^(G12C) mutant,which have shown promise in early clinical trials.The development of allele-specific K-Ras^(G12C) inhibitors marked a new chapter in targeting oncogenic KRAS mutant in cancer.However,drug resistance against these new drugs will likely limit their efficacy in the clinic.Genome-wide approaches have been used to interrogate the mechanisms of resistance to K-Ras^(G12C ) inhibitors,which would facilitate the development of therapeutics overcoming drug resistance.This article reviews the latest progress in resistance to K-Ras^(G12C)-targeted therapies and aims to provide insight in future research targeting drug resistance in cancer.Delong Jiao Shengyu Yang 2020The Innovation2020,1,2:3
13Endoscopic characteristics in predicting prognosis of biopsy-diagnosed gastric low-grade intraepithelial neoplasia显示文摘Background: Endoscopic biopsy can underestimate gastric malignancies as low-grade intraepithelial neoplasia (LGIN). Definitively diagnosed LGIN would progress. This study aimed to evaluate predictive factors to identify malignancies misdiagnosed as LGIN by biopsy and LGIN at high risk of progression.Methods: The clinical records of patients diagnosed with gastric LGIN by endoscopic biopsy who underwent at least two endoscopies during the first year of follow-up between 2007 and 2017 were retrospectively collected. Three endoscopists reviewed photographs of the initial endoscopy, described lesion characteristics, and made endoscopic diagnoses. Logistic regression was used to analyze predictors to identify malignancies underestimated as LGIN. A receiver operating characteristic curve was used to evaluate the diagnostic accuracy of these predictors. Patient clinical outcomes of follow-up >1 year were collected. Kaplan-Meier estimates with log-rank tests and Cox proportional hazards regression were used to analyze predictors of progression.Results: Overall, 48 of 182 (26.4%) patients were proven to have malignancies. A single lesion, a large lesion size, and marked intestinal metaplasia (IM) were independent predictors of initially misdiagnosed malignancies. The area under the curve of these predictors was 0.871, with a sensitivity of 68.7% and specificity of 92.5%. Twelve of 98 patients (12.2%) progressed during the 33-month median follow-up period. A whitish appearance, irregular margins, marked IM, and histological diagnosis of LGIN more than twice within the first year were predictors for progression.Conclusions: Lesions diagnosed as LGIN by biopsy with marked IM and other predictors above should be prudently treated for high potential to be malignancies or progress. Endoscopic follow-up with repeated biopsies within the first year is recommended.Long Zou Qingwei Jiang Tao Guo Xi Wu Qiang Wang Yunlu Feng Shengyu Zhang Weigang Fang Weixun Zhou Aiming Yang 2022Chinese Medical Journal2022,,1:3
14A novel Cu-doped high entropy alloy with excellent comprehensive performances for marine application显示文摘High entropy alloy(HEA)has attracted great interests as one of the promising multifunctional materials in marine applications.However,Cu as an effective biocide tends to form segregation in HEA,which could deteriorate corrosion and induce brittle fracture.Herein,we report a strategy to tailor the existing form of Cu in HEA from undesired large-scale segregation to uniform distribution with dispersed nanoscale precipitation,while retaining the unique structure characteristics of HEA.Eliminating Cu segregation improves toughness and avoids serious corrosion in the grain boundary.Uniform distribution with dispersed nanoscale precipitation of Cu further enhances the antifouling and lubricating abilities of Cu-doped HEA.Tailored AlCoCrFeNiCu_(0.5)HEA in this work has excellent comprehensive properties combining good mechanical properties,outstanding antifouling abilities,superior resistance to corrosion and wear.Furthermore,the corresponded mechanisms are discussed in terms of Cu-segregation-eliminated,nanoscale-Cu-precipitate-forming and comprehensive properties.Yuan Yu Nannan Xu Shengyu Zhu Zhuhui Qjao Jianbin Zhang Jun Yang Weimin Liu 2021Journal of Materials Science & Technology2021,,10:3
15Addition of rituximab is not associated with survival benefit compared with CHOP alone for patients with stage I diffuse large B-cell lymphoma显示文摘Background:The role of rituximab in combination with CHOP regimen in patients with stage I diffuse large B-cell lymphoma(DLBCL) remains to be defined.We aimed to compare CHOP plus rituximab(R-CHOP) with CHOP alone and determine the value of radiotherapy in these patients.Methods:Between 2003 and 2009,140 untreated patients with stage I DLBCL were retrospectively analyzed in this study.Results:Seventy-eight patients were treated in R-CHOP group and 62 in CHOP group.Ninety-one patients received additional radiotherapy at the end of chemotherapy.The different treatment groups were well-balanced with respect to baseline characteristics.Complete response(CR) rate was 77% both in R-CHOP and CHOP groups(P=0.945).After a median follow-up period of 56 months,patients received R-CHOP regimen had similar 5-year progression-free survival(PFS)(76%vs.85%;log-rank P=0.215)and 5-year overall survival(OS)(90%vs.96%;log-rank P=0.175) compared with those with CHOP alone.Patients with radiotherapy had significantly increased 5-year PFS compared with those who had chemotherapy alone(86%vs.71%;log-rank P=0.005).At multivariate analysis,patients who had CR(P=0.008) and received radiotherapy(P=0.003) were significantly associated with superior PFS.Conclusions:CHOP alone could be as effective as R-CHOP regimen and additional radiotherapy would be necessary for stage I or stage I non-bulky DLBCL patients.Bo Jia Yuankai Shi Suyi Kang Sheng Yang Shaoxuan Hu Yexiong Li Mei Dong Weihu Wang Jianliang Yang Liqiang Zhou Peng Liu Shengyu Zhou Yan Qin Lin Gui Changgong Zhang Hua Lin Shanshan Chen Lin Wang Xiaohui He 2015Chinese Journal of Cancer Research2015,27,5:2
16Moderate sewage sludge biochar application on alkaline soil for corn growth:a field study显示文摘In view of the risks induced by the inhibitory effects of applying impracticably large amounts of sewage sludge biochar(SSB)to the alkaline soil,this field study investigated the influence of moderate biochar amendments(0,1500,4500,and 9000 kg/hm2)on corn growth,alkaline soil properties,and the uptake of potentially toxic elements(PTEs).The results showed that applying more SSB would decrease the ammonium nitrogen concentration and increase the available phosphorus and potassium concentrations,which inhibited corn plant growth because of high background nutrient levels of the alkaline soil.When the alkaline soil was amended with 1500 kg/hm2 SSB,the dry weight of 100 niblets increased from 32.11 g in the control to 35.07 g.There was no significant variation in the total concentration of PTEs in the soil.The concentrations of Mn,Ni,Cu,and Zn in niblets decreased from 5.54,0.83,2.26,and 27.15 mg/kg in the control to 4.47,0.62,1.30,and 23.45 mg/kg,respectively.Accordingly,the health risk from corn consumption was significantly reduced.Furthermore,the combination of SSB and fertilizer improved corn growth and reduced the risk of consumption of PTEs.Therefore,considering the increase in corn fruit yield and the decrease in consumption risk,applying 1500 kg/hm2 of biochar to alkaline soils is a realistically achievable rate,which can broaden the utilization of SSB for remediation of different types of soil.Shengyu Xie Guangwei Yu Ruqing Jiang Jianli Ma Xiaofu Shang Gang Wang Yin Wang Yongan Yang Chunxing Li 2021Biochar2021,3,2:2
17Investigation of tribological characteristics of nickel alloybased solid-lubricating composites at elevated temperatures under vacuum显示文摘The development of a high‐performance solid‐lubricating composite with excellent self‐lubricity over a broad temperature range in vacuum is significant to solve the frictional problems of spatial mechanisms.In this study,the vacuum tribological behaviors of nickel‐matrix/Ag/(Ca,Ba)F2/graphite(0–2 wt%)composites were studied from 25 to 800°C.The results show that the synergistic effects of solid lubricants can significantly improve the tribological properties of the composites in vacuum,with the graphite content contributing considerably.For 2 wt%graphite,a low friction coefficient(0.14–0.25)and the lowest wear rate((0.12–4.78)×10^(-5) mm^(3)∙N^(-1)∙m^(-1))were observed in vacuum over the entire testing temperature range.Moreover,the wear mechanisms were clarified via analysis of the chemical composition and morphologies of the sliding surfaces.Jinming ZHEN Jun CHENG Hui TAN Qichun SUN Shengyu ZHU Jun YANG Weimin LIU 2021Friction2021,9,5:2
18Prognostic value of BCL2 and TP53 genetic alterations for diffuse large B-cell lymphoma patients treated with R-CHOP显示文摘Objective:Limited data about the prognostic significance of BCL2 mutations and BCL2 copy number variations in diffuse large B-cell lymphoma(DLBCL)are available.This study aimed to comprehensively describe BCL2 genetic alterations in DLBCL patients,and examine correlation of BCL2,TP53 and other genetic alterations with outcomes in patients treated with R-CHOP.Methods:Probe capture-based high-resolution sequencing was performed on 191 patients diagnosed with de novo DLBCL.MYC,BCL2,and BCL6 protein expressions were detected by immunohistochemistry.Results:The presence of BCL2 alterations significantly correlated with poor progression-free survival(PFS)(5-year PFS:13.7%vs.40.8%;P=0.003)and overall survival(OS)(5-year OS:34.0%vs.70.9%;P=0.036).Importantly,patients who harbored BCL2 gain/amplifications(BCL2GA/AMP)also had a remarkably inferior 5-year PFS(11.1%vs.38.3%;P<0.001)and OS(22.1%vs.69.6%;P=0.009).In contrast,neither BCL2 mutations nor BCL2 translocations were significantly prognostic for survival.Multivariable analyses showed that the presence of BCL2 alterations,especially BCL2GA/AMP,TP53 mutations,and International Prognostic Index(IPI)were significantly associated with inferior PFS and OS.Novel prognostic models for OS were constructed based on 3 risk factors,including BCL2 alterations(Model 1)or BCL2GA/AMP(Model 2),TP53 mutations,and IPI,to stratify patients into 4 risk groups with different survival outcomes.Conclusions:This study showed that DLBCL patients treated with R-CHOP,BCL2 alterations,especially BCL2GA/AMP and TP53 mutations were significantly associated with inferior outcomes,which were independent of the IPI.The novel prognostic models we proposed predicted outcomes for DLBCL patients treated with R-CHOP,but further validation of the prognostic models is still warranted.Yan Qin Haizhu Chen Peng Liu Changgong Zhang Jianliang Yang Lin Gui Xiaohui He Liqiang Zhou Shengyu Zhou Shiyu Jiang Hongxin Jiang Yuankai Shi 2022Cancer Biology & Medicine2022,19,6:2
19Shale gas accumulation conditions and gas-bearing characteristics of the Lower Cambrian Niutitang Formation in Well Changye-1 in northwestern Hunan Province显示文摘To evaluate the accumulation conditions and gas-bearing properties of shale gas in the Lower Cambrian Niutitang Formation,northwestern Hunan Province,the first shale gas parameter well(Well Changye-1)that takes the Niutitang Formation as the target horizon in the Hunan Province was selected preferably and drilled,cumulatively revealing the thickest dark shale horizon of the Niutitang Formation among the single-well drillings in China,with a true vertical thickness of 674.5m.Through analyzing the core samples in terms of organic geochemistry,rock mineralogy and reservoir properties,the black shale horizons in the Niutitang Formation of Well Changye-1 have high organic carbon content(average 3.9%),moderate maturity(equivalent Ro average 2.6%),high brittle mineral content(quartz content average 50.1%),low clay mineral content(average 32.4%),low porosity(1.7%)and low permeability(1.32×10^(-3)mD),and well-developed meso to micro-pores and fractures,indicating good conditions for shale gas accumulation.Field desorption and laboratory isothermal adsorption measurements on core samples show that Well Changye-1 has good gas-bearing properties,and gas content generally increases with depth.The black shale horizons at the depth of 1100-1250m have an average organic carbon content up to 10.1%,total gas content of 0.5-2.1m^(3)/t and 3.7-6.4m^(3)/t,and this is the most favorable depth for shale gas development,indicating that the Niutitang Formation has good a prospect for shale gas exploration.Due to huge sedimentary thickness,the black shale in the middle-lower part of the Niutitang Formation should be given priority for exploration.Tuo Lin Shujing Bao Jinchuan Zhang Zhi Zhou Kun Yuan Bo Li Shengyu Yang 2016Petroleum Research2016,1,2:2
20Injectable self-healing hydrogel with siRNA delivery property for sustained STING silencing and enhanced therapy of intervertebral disc degeneration显示文摘Inflammatory responses of nucleus pulposus(NP)can induce imbalanced anabolism and catabolism of extracellular matrix,and the cytosolic dsDNA accumulation and STING-NF-κB pathway activation found in NP inflammation are considered as fairly important cause of intervertebral disc(IVD)degeneration.Herein,we constructed a siSTING delivery hydrogel of aldehyde hyaluronic acid(HA-CHO)and poly(amidoamine)PAMAM/siRNA complex to intervene the abnormal STING signal for IVD degeneration treatment,where the formation of dynamic Schiff base bonds in the system(siSTING@HPgel)was able to overcome the shortcomings such as low cellular uptake,short half-life,and rapid degradation of siRNA-based strategy.PAMAM not only formed complexes with siRNA to promote siRNA transfection,but also served as dynamic crosslinker to construct hydrogel,and the injectable and self-healing hydrogel efficiently and steadily silenced STING expression in NP cells.Finally,the siSTING@HPgel significantly eased IVD inflammation and slowed IVD degeneration by prolonging STING knockdown in puncture-induced IVD degeneration rat model,revealing that STING pathway was a therapeutic target for IVD degeneration and such novel hydrogel had great potential for being applied to many other diseases for gene delivery.Jiaxin Chen Haifeng Zhu Yutao Zhu Chenchen Zhao Shengyu Wang Yixin Zheng Ziang Xie Yang Jin Honghai Song Linjun Yang Jin Zhang Jiayong Dai Zhijun Hu Huaiyu Wang 2022Bioactive Materials2022,7,3:2
