| 1 | Toripalimab plus chemotherapy as second-line treatment in previously EGFR-TKI treated patients with EGFR-mutant-advanced NSCLC:a multicenter phase-II trial显示文摘This multicenter phase-II trial aimed to investigate the efficacy,safety,and predictive biomarkers of toripalimab plus chemotherapy as second-line treatment in patients with EGFR-mutant-advanced NSCLC.Patients who failed from first-line EGFR-TKIs and did not harbor T790M mutation were enrolled.Toripalimab plus carboplatin and pemetrexed were administrated every three weeks for up to six cycles,followed by the maintenance of toripalimab and pemetrexed.The primary endpoint was objective-response rate(ORR).Integrated biomarker analysis of PD-L1 expression,tumor mutational burden(TMB),CD8+tumor-infiltrating lymphocyte(TIL)density,whole-exome,and transcriptome sequencing on tumor biopsies were also conducted.Forty patients were enrolled with an overall ORR of 50.0%and disease-control rate(DCR)of 87.5%.The median progression free survival(PFS)and overall survival were 7.0 and 23.5 months,respectively.The most common treatment-related adverse effects were leukopenia,neutropenia,anemia,ALT/AST elevation,and nausea.Biomarker analysis showed that none of PD-L1 expression,TMB level,and CD8+TIL density could serve as a predictive biomarker.Integrated analysis of whole-exome and transcriptome sequencing data revealed that patients with DSPP mutation had a decreased M2 macrophage infiltration and associated with longer PFS than those of wild type.Toripalimab plus chemotherapy showed a promising anti-tumor activity with acceptable safety profiles as the second-line setting in patients with EGFR-mutant NSCLC.DSPP mutation might serve as a potential biomarker for this combination.A phase-III trial to compare toripalimab versus placebo in combination with chemotherapy in this setting is ongoing(NCT03924050). | Tao Jiang Pingyang Wang Jie Zhang Yanqiu Zhao Jianying Zhou Yun Fan Yongqian Shu Xiaoqing Liu Helong Zhang Jianxing He Guanghui Gao Xiaoqian Mu Zhang Bao Yanjun Xu Renhua Guo Hong Wang Lin Deng Ningqiang Ma Yalei Zhang Hui Feng Sheng Yao Jiarui Wu Luonan Chen Caicun Zhou Shengxiang Ren | 2021 | Signal Transduction and Targeted Therapy2021，6，11： | 8 |
| 2 | Phase I study of chimeric anti-CD20 monoclonal antibody in Chinese patients with CD20-positive non-Hodgkin's lymphoma显示文摘Objective: This study was designed to determine the safety, pharmacokinetics and biologic effects of a humanmouse chimeric anti-CD20 monoclonal antibody(SCT400) in Chinese patients with CD20-positive B-cell nonHodgkin's lymphoma(CD20+ B-cell NHL). SCT400 has an identical amino acid sequence as rituximab, with the exception of one amino acid in the CH1 domain of the heavy chain, which is common in Asians.Methods: Fifteen patients with CD20+ B-cell NHL received dose-escalating SCT400 infusions(250 mg/m^2: n=3; 375 mg/m^2: n=9; 500 mg/m^2: n=3) once weekly for 4 consecutive weeks with a 24-week follow-up period. The data of all patients were collected for pharmacokinetics and pharmacodynamics analyses.Results: No dose-limiting toxicities were observed. Most drug-related adverse events were grade 1 or 2. Two patients had grade 3 or 4 neutropenia. Under premedication, the drug-related infusion reaction was mild. A rapid, profound and durable depletion of circulating B cells was observed in all dose groups without significant effects on T cell count, natural killer(NK) cell count or immunoglobulin levels. No patient developed antiSCT400 antibodies during the course of the study. SCT400 serum half-life(T1/2), maximum concentration(Cmax) and area under the curve(AUC) generally increased between the first and fourth infusions(P<0.05). At the 375 mg/m^2 dose, the T1/2 was 122.5±46.7 h vs. 197.0±75.0 h, respectively, and the Cmax was 200.6±20.2 μg/m L vs. 339.1±71.0 μg/m L, respectively. From 250 mg/m^2 to 500 mg/m^2, the Cmax and AUC increased significantly in a dose-dependent manner(P<0.05). Patients with a high tumor burden had markedly lower serum SCT400 concentrations compared with those without or with a low tumor burden. Of the 9 assessable patients, 1 achieved complete response and 2 achieved partial responses.Conclusions: SCT400 is well-tolerated and has encouraging preliminary efficacy in Chinese patients with CD20+ B-cell NHL. | Lin Gui Xiaohong Han Xiaohui He Yuanyuan Song Jiarui Yao Jianliang Yang Peng Liu Yan Qin Shuxiang Zhang Weijing Zhang Wenlin Gai Liangzhi Xie Yuankai Shi | 2016 | Chinese Journal of Cancer Research2016，28，2： | 5 |
| 3 | Autologous 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 | 2015 | Chinese Journal of Cancer2015，34，11： | 4 |
| 4 | Laser-driven plasma collider for nuclear studies显示文摘A novel method of initiating nuclear fusion reactions in a full plasma environment was suggested, and a proof-of-concept experiment was carried out with the D t D ! n t3 He reaction. In this new approach, two plasma jets generated by high-intensity lasers collide headon-head. The center-of-mass energy of the nuclei increases accordingly, and therefore, reaction products can be significantly enhanced, especially in the sub-Coulomb barrier ranges. As a result of the fusion reaction, up to 7:6 105 neutrons had been observed. This new type of ‘‘plasma collider'' could provide an innovative tool to study nuclear reactions under astrophysical conditions. | Changbo Fu Jie Bao Liming Chen Jianjun He Long Hou Liang Li Yanfei Li Yutong Li Guoqian Liao Yongjoo Rhee Yang Sun Shiwei Xu Dawei Yuan Xiaopeng Zhang Gang Zhao Jiarui Zhao Baojun Zhu Jianqiang Zhu Jie Zhang | 2015 | Science Bulletin2015，60，13： | 2 |
| 5 | Processes and events in the centre:a dynamic data model for representing spatial change显示文摘Traditional geographic information system models for map representation use superposition of layers to model physical reality,neglecting the integrity of the environment and limiting the ability to express interactions between features in complex phenomenon.This results in limitations regarding dynamic simulation and geographic causality reasoning.In this paper,we extend the framework of the geographic scene by formalizing the relationship between geographic processes and events to construct a dynamic data model:the process-event-centred dynamic data model.The key element of this data model is relationships between processes,events,and states of the natural or man-made phenomenon of interest.The identified relationships can be translated into a network of hierarchical,developmental,and causal graphs and realized in the Neo4j graph database.The implementation in the graph database supports spatio-temporal reasoning in geographic scenes and achieves an organizational framework for simulating spatio-temporal dynamics and complex calculations.The example of a 2019 mega-typhoon process is used to demonstrate the introduced process-event-centred model and its implementation in the graph database.A series of queries to the graph database show the capabilities of the data model for spatial reasoning and dynamic modeling. | Yufeng He Yehua Sheng Barbara Hofer Yi Huang Jiarui Qin | 2022 | International Journal of Digital Earth2022，15，1： | 1 |
| 6 | Biomechanical evaluation of two fusion techniques based on finite element analysis:Percutaneous endoscopic and minimally invasive transforaminal lumbar interbody fusion显示文摘As a novel minimally invasive technique,percutaneous endoscopic transforaminal lumbar interbody fusion(PETLIF)has been widely used in the treatment of lumbar degenerative diseases.The purpose of this study was to analyze these two operation types’biomechanical performances of PE-TLIF and traditional minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)using the finite element(FE)method.The intact FE models of L4-L5 were established and validated based on the CT images.On this basis,the FE models of MIS-TLIF and PETLIF were established and analyzed.It is demonstrated that for lumbar interbody fusion with the oblique asymmetrically implanted cage under bilateral pedicle screws and rods fixation,such as MIS-TLIF and PE-TLIF,different degrees of articular process resection have no significant effect on the cage subsidence,and the surgical segment can achieve similar stability.In addition,the maximum stress of the L4 inferior endplate of MIS-TLIF and PE-TLIF is greater than that of the L5 superior endplate,which indicates that MIS-TLIF and PE-TLIF can cause cage subsidence in the L4 inferior endplate. | Yang Yan Jiarui Li Jianhao Yu Yan Wang Hao Dong Yuqin Sun Xiaogang Wu Liming He Weiyi Chen Haoyu Feng | 2022 | Medicine in Novel Technology and Devices2022，，4： | 1 |
| 7 | Promoted reactants activation and charge separation leading to efficient photocatalytic activity on phosphate/potassium co-functionalized carbon nitride显示文摘Photocatalytic technology has been widely adopted to address the issue of air pollution. The separation of photogenerated carriers and the activation of reactants on catalyst surface are the main factors that affect the photocatalytic efficiency. Here, the phosphate/potassium(PO_4/K) cofunctionalized carbon nitride(labeled as PO_4-CN-K) was synthesized via a one-step in situ copyrolysis of thiourea and potassium phosphate. The unique electronic structure of PO_4-CN-K could significantly improve the performance of photocatalytic NO purification. The enhanced activity of PO_4-CN-K can be attributed to the promoted activation capacity for O_2, NO and H_2O on the catalyst surface,the decreased of carriers recombination, benefiting from the co-functionalization of phosphate groups on the surface of CN and the construction of K channels between CN layers. The photocatalytic NO conversion pathway is disclosed through time-dependent in situ FT-IR, indicating that PO_4-CN-K can efficiently convert NO molecules into harmless nitrate via the NO→NO+→nitrate/nitrite routes. The research provides a novel strategy to impel the development of photocatalytic technology for efficient air purification. | Maoxi Ran Peng Chen Jiarui Li Wen Cui Jieyuan Li Ye He Jianping Sheng Yanjuan Sun Fan Dong | 2019 | Chinese Chemical Letters2019，30，4： | 1 |
| 8 | Pathobiology of ovarian carcinomas显示文摘Ovarian tumors comprise a heterogeneous group of lesions, displaying distinct tumor pathology and oncogenic potentiel. These tumors are subdivided into three main categories: epithelial, germ cell, and sex-cord stromal tumors. We report herein the newly described molecular abnormalities in epithelial ovarian cancers(carcinomas). Immunohistochemistry and molecular testing help pathologists to decipher the significant heterogeneity of this disease. Our better understanding of the molecular basis of ovarian carcinomas represents the first step in the development of targeted therapies in the near future. | 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 | 2015 | Chinese Journal of Cancer2015，34，1： | 1 |
| 9 | ON THE GOLD-DEPOSIT OF SHEARZONE-TYPE AND ITS CLASSIFICATION显示文摘The gold-deposit of shearzone-type(GST)resulting predominantly from shearing is controlled by ductile shearzones,and its general characteristics are discussed in this paper.GST can be classified differently according to its characteristics,and the the authors offer three ways,namely the classification based on the characterisics and genesis of ore-deposits,on the occurrence of shear zones,and on the formation conditions of shear zones. | He Shaoxun Duan Jiarui Zhou Chongzhi Peng Shaomei | 1992 | Transactions of Nonferrous Metals Society of China1992，2，2： | 0 |
| 10 | Tuning Surface Spin Polarization of CoFeB by Boron Diffusion Detected by Spin Resolved Photoemission显示文摘Research of spin polarization of magnetic CoFeB thin films is of practical importance in spintronic applications.Here,using a direct characterization technique of spin-resolved photoemission spectroscopy,we obtain the surface spin polarization of amorphous Co_(40)Fe_(40)B_(20)thin films with different annealing temperatures from 100℃to 500℃prepared by magnetron sputtering.After high annealing temperature,a quasi-semiconductor state is gradually formed at the CoFeB surface due to the boron diffusion.While the global magnetization remains almost constant,the secondary electrons’spin polarization,average valence band spin polarization and the spin polarization at Fermi level from spin-resolved photoemission spectroscopy show a general trend of decreasing with the increasing annealing temperature above 100℃.These distinct surface properties are attributed to the enhanced Fe-B bonding due to the boron segregation upon surface after annealing as confirmed by x-ray photoelectron spectroscopy and scanning transmission electron microscopy with energy dispersive spectroscopy.Our findings provide insight into the surface spin-resolved electronic structure of the CoFeB thin films,which should be important for development of high-performance magnetic random-access memories. | Qi Liu Xianyang Lu Chengrui Fu Jiarui Chen Zhe Zhang Yuting Gong Xinyue Wang Yu Yan Qinwu Gao Hui Li Xuezhong Ruan Yao Li Jun Du Jing Wu Liang He Bo Liu Rong Zhang Yongbing Xu | 2023 | Chinese Physics Letters2023，40，8： | 0 |
| 11 | Status of transjugular intrahepatic portosystemic shunt for portal hypertension in China:A national survey analysis显示文摘Aim:The transjugular intrahepatic portosystemic shunt(TIPS)procedure has been performed in China for 30 years,but our understanding of the status and difficulties associated with the use of TIPS for portal hypertension is incomplete.This study aims to investigate the current situation of the use of TIPS for portal hypertension,which should aid the development of TIPS in China.Methods:This study involved a questionnaire survey,initiated by the China Portal Hypertension Alliance(CHESS)to investigate the use of TIPS for portal hypertension in China.Questionnaires were released on the Internet between August 16,2022 and September 16,2022.Detailed information was collected from 545 hospitals contracted by the CHESS in China,which performed TIPS surgery in 2021.Results:The 545 hospitals covers the majority of hospitals in China that conduct TIPS intervention.In the survey,a total of 13,527 TIPS interventions were carried out with 94.1%(498/545)of them had a system of routine follow‐up after TIPS.The majority(42.6%[232/545])believed that the main indication of TIPS was the control of acute bleeding.Overall,48.1%(262/545)carried out early or pre‐emptive TIPS,53.0%(289/545)carried out TIPS for cavernous transformation of the portal vein,and 81.0%(441/545)chose routine embolization of collateral circulation during operation.Most used coils(97.0%[475/490])and biological glue(72.0%[353/490])as embolic materials,and 78.5%(428/545)routinely performed intraoperative portal pressure gradient measurements.When selecting TIPS stents,57.1%(311/545)chose viator‐specific stents,and 57.2%(312/545)chose conventional anticoagulation after TIPS.Conventional anticoagulation after TIPS is over a time interval of 3–6 months(55.4%[173/312]).The limitation of TIPS surgery is mainly its cost(72.3%[394/545])and insufficient understanding of the procedure by doctors in other related departments(77.4%[422/545]).Most of the hospital teams accept the use of domestic instruments in TIPS surgery(92.7%[505/545]).Conclusions:This survey shows that TIPS is an essential part of the treatment of portal hypertension in China.TIPS is widely used in Chinese patients with portal hypertension,and this survey presents a more comprehensive picture of the options and difficulties encountered in the implementation of TIPS.In the future,it is necessary to promote TIPS technology and further standardize surgical indications,routine operations,and instrument application. | Haibo Shao Xinwei Han Jianbo Zhao Junhui Sun Zhuting Fang Bin Xiong Xiaoli Zhu Weixin Ren Min Yuan Shiping Yu Meng Niu Weifu Lv Xueqiang Zhang Chunqing Zhang Lei Li Xuefeng Luo Yusheng Song Yilong Ma Tong Dang Hua Xiang Yun Jin Hui Xue Guiyun Jin Xiao Li Jiarui Li Shi Zhou Changlu Yu Song He Lei Yu Hongmei Zu Jun Ma Yanming Lei Ke Xu Xiaolong Qi | 2023 | Portal Hypertension & Cirrhosis2023，2，1： | 0 |

| 13 | Recombinant human thrombopoietin prior to mobilization chemotherapy facilitates platelet recovery in autologous transplantation in patients with lymphoma:Results of a prospective randomized study显示文摘Background:Chemotherapy plus granulocyte colony-stimulating factor (GCSF) regimen is one of the available approaches to mobilize peripheral blood progenitor cells (PBPCs).It causes thrombocytopenia and delays leukapheresis.This study aimed to evaluate the role of recombinant human thrombopoietin (rhTPO) before mobilization chemotherapy in facilitating leukapheresis in patients with lymphoma.Methods:In this randomized open-label phase 2 trial, patients were randomly assigned in a 1:2 ratio to receive mobilization with rhTPO plus GCSF in combination with chemotherapy (the rhTPO plus GCSF arm) or GCSF alone in combination with chemotherapy (the GCSF alone arm).The recovery of neutrophils and platelets and the amount of platelet transfusion were monitored.Results:Thirty patients were enrolled in this study between March 2016 and August 2018. Patients in the rhTPO plus GCSF arm (n = 10) had similar platelet nadir after mobilization chemotherapy (P=0.878) and similar amount of platelet transfusion (median 0 vs.1 unit,P=0.735) when compared with the GCSF alone arm (n = 20). On the day of leukapheresis, the median platelet count was 86 ×10^(9)/L (range 18-219) among patients who received rhTPO and 73 ×10^(9)/L (range 42-197) among those who received GCSF alone (P=0.982). After the use of rhTPO, the incidence of platelet count <75 ×10^(9)/L on the day of leukapheresis did not decrease significantly (30.0% vs. 50.0%,P=0.297).Platelet recovery after PBPC transfusion was more rapid in the rhTPO plus GCSF arm (median 8.0 days [95% confidence interval 2.9-13.1] to platelets ≥50 ×10^(9)/L vs. 11.0 days [95% confidence interval 8.6-13.4],P=0.011).The estimated total cost of the mobilization and reconstitution phases per patient was similar between the two treatmtent groups (P=0.362 andP=0.067,respectively).Conclusions:Our findings indicate that there was no significant clinical benefit of rhTPO use in facilitating mobilization of progenitor cells,but it may promote platelet recovery in the reconstitution phase after high-dose therapy.Trial registration:This trial has been registered in Clinicaltrials.gov as NCT03014102. | Hongnan Mo Peng Liu Yan Qin Xiaohui He Xiaohong Han Jiarui Yao Weicai Su Shuxiang Zhang Le Tang Fengyi Zhao Lin Gui Sheng Yang Jianliang Yang Shengyu Zhou Zhishang Zhang Yuankai Shi | 2021 | Chronic Diseases and Translational Medicine2021，7，3： | 0 |
| 14 | Anti-tumor Effect of Newcastle Disease Virus Expressing IL-2 in Lung Cancer Model显示文摘Recombinant Newcastle disease virus(rNDV)has shown an anti-cancer effect in preclinical studies,but has never been tested for lung cancer models.This study explored the anti-cancer activity of genetically modified NDV expressing IL-2(rNDV–IL-2)in lung cancer models.This study used Lewis lung carcinoma cell line(LLC)to create tumor models in C57 female mice,the tumor-bearing mice were treated with rNDV-IL-2,rNDV and phosphate-buffered saline(PBS),respectively.In vitro results revealed that rNDV effectively infected malignant cells and expressed IL-2,in vivo results revealed that rNDV expressing IL-2 was highly efficient in inhibiting lung cancer tumors,with an average tumor size of 291.255 mm^3 in rNDV-IL-2 group compared to 763.068 mm^3 in rNDV group and 1101.68 mm^3 in PBS group.For the survival studies,treatment with rNDV-IL-2 enhanced the survival rates of tumor-bearing mice by 36%compared to those of rNDV treated mice and by 80%compared to those of vehicle-treated mice(survival rate:12 out of 15 for rNDV-IL-2 group;seven out of 15 for rNDV group and zero out of 15 for vehicle group).These results demonstrated that rNDV-expressed IL-2 enhanced the intrinsic anti-tumor ability of Newcastle disease virus in lung cancer models by further restrain of lung tumor growth and improvement of the survival rates of the tumor-bearing mice.The genetically modified rNDV-IL-2 was a good candidate for lung cancer therapy. | Li De-shan Jiang Shan Liu Yun-ye Rasoul Lubna He Jin-jiao Mir Hassan Khoso Cao Hong-xue Yang Jiarui Yin He Yin Jie-chao | 2020 | Journal of Northeast Agricultural University(English Edition)2020，27，2： | 0 |
| 15 | A Critical Role for γCaMKII in Decoding NMDA Signaling to Regulate AMPA Receptors in Putative Inhibitory Interneurons显示文摘CaMKII is essential for long-term potentiation(LTP),a process in which synaptic strength is increased following the acquisition of information.Among the four CaMKII isoforms,γCaMKII is the one that mediates the LTP of excitatory synapses onto inhibitory interneurons(LTPE→I).However,the molecular mechanism underlying howγCaMKII mediates LTPE→I remains unclear.Here,we show thatγCaMKII is highly enriched in cultured hippocampal inhibitory interneurons and opts to be activated by higher stimulating frequencies in the 10–30 Hz range.Following stimulation,γCaMKII is translocated to the synapse and becomes co-localized with the postsynaptic protein PSD-95.Knocking downγCaMKII prevents the chemical LTP-induced phosphorylation and trafficking of AMPA receptors(AMPARs)in putative inhibitory interneurons,which are restored by overexpression ofγCaMKII but not its kinase-dead form.Taken together,these data suggest thatγCaMKII decodes NMDAR-mediated signaling and in turn regulates AMPARs for expressing LTP in inhibitory interneurons. | Xingzhi He Yang Wang Guangjun Zhou Jing Yang Jiarui Li Tao Li Hailan Hu Huan Ma | 2022 | Neuroscience Bulletin2022，38，8： | 0 |
| 16 | THEORETICAL STUDY ON ALEKSANDROWSKI′S METHOD OF THE GRAPHICAL DETERMINATION OF PRINCIPAL STRESS DIRECTIONS FROM THE FAULT SLIP DATA SETS显示文摘A graphical method for determining the principal stress distribution of a triaxial stress state from a fault slipstate was proposed by Aleksandrowski in 1985,based on Arthaud′s concept of plane movement,Alek-sandrowski′s method,however,is only valid for the cases in which the values of the stress ratios(C)are consid-ered 1o be ,10,2,1.1 and 1.Whether the method is applicable for general cases of all values of C has not yetbeen confirmed.In this paper.Aleksandrowskis′ method is tested using a numerical derivation from spatialgeometric analysis,and it is revealed that this method is correct for all values of stress ratios other than C=,10,2,1.1,and 1,i.c-<C<. | Zhang,Yinqi He,Shaoxun Duan,Jiarui Central South University of Technology,Changsha 410083,China | 1993 | 中国有色金属学会会刊:英文版1993，3，2： | 0 |
| 17 | Identification of Bulbocodin D and C as novel STAT3 inhibitors and their anticancer activities in lung cancer cells显示文摘Cancer stands as one of the predominant causes of mortality globally, necessitating ongoing efforts to develop innovative therapeutics. Historically, natural products have been foundational in the quest for anticancer agents. Bulbocodin D (BD) and Bulbocodin C (BC), two bibenzyls derived from Pleione bulbocodioides (Franch.) Rolfe, have demonstrated notable in vitro anticancer activity. In human lung cancer A549 cells, the IC50s for BD and BC were 11.63 and 11.71 μmol·L^(−1), respectively. BD triggered apoptosis, as evidenced by an upsurge in Annexin V-positive cells and elevated protein expression of cleaved-PARP in cancer cells. Furthermore, BD and BC markedly inhibited the migratory and invasive potentials of A549 cells. The altered genes identified through RNA-sequencing analysis were integrated into the CMap dataset, suggesting BD’s role as a potential signal transducer and activator of transcription 3 (STAT3) inhibitor. SwissDock and MOE analyses further revealed that both BD and BC exhibited a commendable binding affinity with STAT3. Additionally, a surface plasmon resonance assay confirmed the direct binding affinity between these compounds and STAT3. Notably, treatment with either BD or BC led to a significant reduction in p-STAT3 (Tyr 705) protein levels, regardless of interleukin-6 stimulation in A549 cells. In addition, the extracellular signal-regulated kinase (ERK) was activated after BD or BC treatment. An enhancement in cancer cell mortality was observed upon combined treatment of BD and U0126, the MEK1/2 inhibitor. In conclusion, BD and BC emerge as promising novel STAT3 inhibitors with potential implications in cancer therapy. | HE Xinyu FU Jiarui LYU Wenyu HUANG Muyang MO Jianshan CHENG Yaxin XU Yulian ZHENG Lijun ZHANG Xiaolei QI Lu ZHANG Lele ZHENG Ying HUANG Mingqing NI Lin LU Jinjian | 2023 | Chinese Journal of Natural Medicines2023，21，11： | 0 |
