| 1 | Autophagy: a double-edged sword for neuronal survival after cerebral ischemia显示文摘Evidence suggests that autophagy may be a new therapeutic target for stroke, but whether activation of autophagy increases or decreases the rate of neuronal death is still under debate. This review summarizes the potential role and possible signaling pathway of autophagy in neuronal survival after cerebral ischemia and proposes that autophagy has dual effects. | Wenqi Chen Yinyi Sun Kangyong Liu Xiaojiang Sun | 2014 | Neural Regeneration Research2014，9，12： | 57 |
| 2 | Level of circulating PD-L1 expression in patients with advanced gastric cancer and its clinical implications显示文摘Objective:The programmed cell death-1 receptor/programmed cell death-1 ligand(PD-1/PD-L1) pathway plays a crucial role in tumor evasion from host immunity.This study was designed to evaluate the association between circulating PD-L1 expression and prognosis in patients with advanced gastric cancer.Methods:Totally 80 advanced gastric cancer patients and 40 health controls from Beijing Cancer Hospital were enrolled in the present study.Circulating PD-L1 expression was tested by enzymelinked immunosorbent assay(ELISA).The associations between the expression level of PD-L1 and clinicopathological features and prognosis were analyzed statistically.Results:Expression of PD-L1 in advanced gastric cancer patients was significantly up-regulated compared with health people(P=0.006).The expression of PD-L1 was significantly correlated with differentiation and lymph node metastasis(P=0.026 and P=0.041,respectively).Although we didn't find significant difference in all advanced gastric cancer patients with different PD-L1 expression,the adenocarcinoma patients with higher up-regulated PD-L1 expression had much better prognosis than low expression patients(65.6% vs.44.7%,P=0.028).Conclusions:PD-L1 was elevated in advance gastric cancer patients and may play an important role in tumor immune evasion and patients prognosis. | Zhixue Zheng Zhaode Bu Xijuan Liu Lianhai Zhang Ziyu Li Aiwen Wu Xiaojiang Wu Xiaojing Cheng Xiaofang Xing Hong Du Xiaohong Wang Ying Hu Jiafu Ji | 2014 | Chinese Journal of Cancer Research2014，26，1： | 37 |

| 5 | Construction and external validation of a nomogram that predicts lymph node metastasis in early gastric cancer patients using preoperative parameters显示文摘Objective: To create a nomogram to predict the incidence of lymph node metastasis(LNM) in early gastric cancer(EGC) patients and to externally validate the nomogram.Methods: To construct the nomogram,we retrospectively analyzed a primary cohort of 272 EGC patients.Univariate analysis and a binary logistic regression were performed.A nomogram predicting the incidence of LNM in EGC patients was created.The discrimination ability of the nomogram was measured using the concordance index(c-index),and the nomogram was also calibrated.Then,another prospective cohort of 81 patients was analyzed to validate the nomogram.Results: In the primary cohort,LNM was pathologically confirmed in 37(13.6%) patients.In multivariate analysis,the presence of an ulcer,the maximum lesion diameter observed via gastroscopy,the thickness of the lesion observed via endoscopic ultrasonography,and the presence of enlarged lymph nodes on computed tomography(CT) were independent risk factors for LNM.A nomogram was then created based on the regression model with the c-index of 0.905,and the calibration curve of the nomogram fell approximately on the ideal 45-degree line.The cut-off score of the nomogram was 110,and the sensitivity,specificity,positive predictive and negative predictive values of the nomogram in the primary cohort were 81.1%,86.0%,47.6% and 96.7%,respectively,and in the prospective validation cohort were 75.0%,91.0%,60.0% and 95.5%,respectively.The calibration curve of the external validation cohort was almost on the 45-degree line.Conclusions: We developed an effective nomogram predicting the incidence of LNM for EGC patients. | Yinan Zhang Yiqiang Liu Ji Zhang Xiaojiang Wu Xin Ji Tao Fu Ziyu Li Qi Wu Zhaode Bu Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，6： | 12 |
| 6 | Study on stabilities and electrochemical behavior of V(V) electrolyte with acid additives for vanadium redox flow battery显示文摘Several acid compounds have been employed as additives of the V(V) electrolyte for vanadium redox flow battery(VRB) to improve its stability and electrochemical activity. Stability of the V(V) electrolyte with and without additives was investigated with ex-situ heating/cooling treatment at a wide temperature range of-5 ?C to 60 ?C. It was observed that methanesulfonic acid, boric acid, hydrochloric acid, trifluoroacetic acid,polyacrylic acid, oxalic acid, methacrylic acid and phosphotungstic acid could improve the stability of the V(V) electrolyte at a certain range of temperature. Their electrochemical behaviors in the V(V) electrolyte were further studied by cyclic voltammetry(CV), steady state polarization and electrochemical impedance spectroscopy(EIS). The results showed that the electrochemical activity, including the reversibility of electrode reaction, the diffusivity of V(V) species, the polarization resistance and the flexibility of charge transfer for the V(V) electrolyte with these additives were all improved compared with the pristine solution. | Gang Wang Jinwei Chen Xueqin Wang Jing Tian Hong Kang Xuejing Zhu Yu Zhang Xiaojiang Liu Ruilin Wang | 2014 | Journal of Energy Chemistry2014，23，1： | 10 |
| 7 | COVID-19 in cancer patients:risk,clinical features,and management显示文摘A novel coronavirus known as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has spread across the world,prompting the World Health Organization to declare the coronavirus disease of 2019(COVID-19)a public health emergency of international concern.Cancer patients are regarded as a highly vulnerable population to SARS-CoV-2 infection and development of more severe COVID-19 symptoms,which is possibly due to the systemic immunosuppressive state caused directly by tumor growth and indirectly by effects of anticancer treatment.Currently,much effort has been directed toward studying the pathogenesis and treatment of COVID-19,but the risk profiles,prognoses,and treatment outcomes in cancer patients remain unclear.Based on the current literature,we summarize the risk profiles,clinical and biochemical characteristics,and therapy outcomes of COVID-19 infections in cancer patients.The challenges in the clinical care of cancer patients with COVID-19 are discussed.The goal of this review is to stimulate research to better understand the biological impact and prognoses of COVID-19 infections in cancer patients,thus facilitating improvement of the clinical management of these patients. | Cuiwei Liu Yanxia Zhao Derick Okwan-Duodu Reva Basho Xiaojiang Cui | 2020 | Cancer Biology & Medicine2020，17，3： | 8 |
| 8 | Face Detection Detection, Alignment Alignment, Quality Assessment and Attribute Analysis with Multi-Task Hybrid Convolutional Neural Networks显示文摘This paper proposes a universal framework,termed as Multi-Task Hybrid Convolutional Neural Network(MHCNN),for joint face detection,facial landmark detection,facial quality,and facial attribute analysis.MHCNN consists of a high-accuracy single stage detector(SSD)and an efficient tiny convolutional neural network(T-CNN)for joint face detection refinement,alignment and attribute analysis.Though the SSD face detectors achieve promising results,we find that applying a tiny CNN on detections further boosts the detected face scores and bounding boxes.By multi-task training,our T-CNN aims to provide five facial landmarks,facial quality scores,and facial attributes like wearing sunglasses and wearing masks.Since there is no public facial quality data and facial attribute data as we need,we contribute two datasets,namely FaceQ and FaceA,which are collected from the Internet.Experiments show that our MHCNN achieves face detection performance comparable to the state of the art in face detection data set and benchmark(FDDB),and gets reasonable results on AFLW,FaceQ and FaceA. | GUO Da ZHENG Qingfang PENG Xiaojiang LIU Ming | 2019 | ZTE Communications2019，17，3： | 5 |
| 9 | Pharmacological Modulation of Vagal Nerve Activity in Cardiovascular Diseases显示文摘Cardiovascular diseases are life-threatening illnesses with high morbidity and mortality. Suppressed vagal(parasympathetic) activity and increased sympathetic activity are involved in these diseases. Currently, pharmacological interventions primarily aim to inhibit overexcitation of sympathetic nerves, while vagal modulation has been largely neglected. Many studies have demonstrated that increased vagal activity reduces cardiovascular risk factors in both animal models and human patients.Therefore, the improvement of vagal activity may be an alternate approach for the treatment of cardiovascular diseases. However, drugs used for vagus nerve activation in cardiovascular diseases are limited in the clinic. In this review, we provide an overview of the potential drug targets for modulating vagal nerve activation, including muscarinic, and b-adrenergic receptors. In addition,vagomimetic drugs(such as choline, acetylcholine, and pyridostigmine) and the mechanism underlying their cardiovascular protective effects are also discussed. | Longzhu Liu Ming Zhao Xiaojiang Yu Weijin Zang | 2019 | Neuroscience Bulletin2019，35，1： | 5 |

| 11 | C.elegans-based screen identifies lysosome-damaging alkaloids that induce STAT3-dependent lysosomal cell death显示文摘Lysosomes are degradation and signaling centers within the cell,and their dysfunction impairs a wide variety of cellular processes.To understand the cellular effect of lysosome damage,we screened natural smallmolecule compounds that induce iysosomal abnormality using Caenorhabditis elegans (C.elegans)as a model system.A group of vobasinyl-ibogan type bisindole alkaloids (ervachinines A-D)were identified that caused lysosome enlargement in C.elegans macrophage-like cells.Intriguingly,these compounds triggered cell death in the germ line independently of the canonical apoptosis pathway.In mammalian cells, ervachinines A-D induced lysosomal enlargement and damage,leading to leakage of cathepsin proteases, inhibition of autophagosome degradation and necrotic cell death.Further analysis revealed that this ervachinine-induced lysosome damage and lysosomal cell death depended on STAT3 signaling,but not RIP1 or RIP3 signaling.These findings suggest that lysosomedamaging compounds are promising reagents for dissecting signaling mechanisms underlying lysosome homeostasis and lysosome-related human disorders. | Yang Li Yu Zhang Qiwen Gan Meng Xu Xiao Ding Guihua Tang Jingjing Liang Kai Liu Xuezhao Liu Xin Wang Lingli Guo Zhiyang Gao Xiaojiang Hao Chonglin Yang | 2018 | Protein & Cell2018，9，12： | 2 |
| 12 | The role of autophagic and lysosomal pathways in ischemic brain injury显示文摘Autophagy is involved in neural cell death after cerebral ischemia. Our previous studies showed that rapamycin-induced autophagy decreased the rate of apoptosis, but the rate of apoptosis was in-creased after the autophagy inhibitor, 3-methyladenine, was used. In this study, a suture-occluded method was performed to generate a rat model of brain ischemia. Under a transmission electron microscope, autophagic bodies and autophagy lysosomes were markedly accumulated in neurons at 4 hours post brain ischemic injury, with their numbers gradually reducing over time. Western blotting demonstrated that protein levels of light chain 3-II and cathepsin B were significantly in-creased within 4 hours of ischemic injury, but these levels were not persistently upregulated over time. Confocal microscopy showed that autophagy was mainly found in neurons with positive light chain 3 signal. Injection of rapamycin via tail vein promoted the occurrence of autophagy in rat brain tissue after cerebral ischemia and elevated light chain 3 and cathepsin B expression. However, in-jection of 3-methyladenine significantly diminished light chain 3-II and cathepsin B expression. Results verified that autophagic and lysosomal activity is increased in ischemic neurons. Abnormal components in cells can be eliminated through upregulating cell autophagy or inhibiting autophagy after ischemic brain injury, resulting in a dynamic balance of substances in cells. Moreover, drugs that interfere with autophagy may be potential therapies for the treatment of brain injury. | Zhaohua Gu Yinyi Sun Kangyong Liu Fen Wang Ting Zhang Qiang Li Liwei Shen Ling Zhou Liang Dong Nan Shi Qian Zhang Wei Zhang Meizhen Zhao Xiaojiang Sun | 2013 | Neural Regeneration Research2013，8，23： | 2 |
| 13 | Nomogram for predicting lymph node metastasis rate of submucosal gastric cancer by analyzing clinicopathological characteristics associated with lymph node metastasis显示文摘Background:To combine clinicopathological characteristics associated with lymph node metastasis for submucosal gastric cancer into a nomogram.Methods:We retrospectively analyzed 262 patients with submucosal gastric cancer who underwent D2 gastrectomy between 1996 and 2012.The relationship between lymph node metastasis and clinicopathological features was statistically analyzed.With multivariate logistic regression analysis,we made a nomogram to predict the possibility of lymph node metastasis.Receiver operating characteristic(ROC) analysis was also performed to assess the predictive value of the model.Discrimination and calibration were performed using internal validation.Results:A total number of 48(18.3%) patients with submucosal gastric cancer have pathologically lymph node metastasis.For submucosal gastric carcinoma,lymph node metastasis was associated with age,tumor location,macroscopic type,size,differentiation,histology,the existence of ulcer and lymphovascular invasion in univariate analysis(all P<0.05).The multivariate logistic regression analysis identified that age ≤50 years old,macroscopic type III or mixed,undifferentiated type,and presence of lymphovascular invasion were independent risk factors of lymph node metastasis in submucosal gastric cancer(all P<0.05).We constructed a predicting nomogram with all these factors for lymph node metastasis in submucosal gastric cancer with good discrimination [area under the curve(AUC)=0.844].Internal validation demonstrated a good discrimination power that the actual probability corresponds closely with the predicted probability.Conclusions:We developed a nomogram to predict the rate of lymph node metastasis for submucosal gastric cancer.With good discrimination and internal validation,the nomogram improved individualized predictions for assisting clinicians to make appropriated treatment decision for submucosal gastric cancer patients. | Zhixue Zheng Yinan Zhang Lianhai Zhang Ziyu Li Aiwen Wu Xiaojiang Wu Yiqiang Liu Zhaode Bu Jiafu Ji | 2015 | Chinese Journal of Cancer Research2015，27，6： | 2 |
| 14 | Endovascular stent-grafts for acute and chronic type B aortic dissection: comparison of clinical outcomes显示文摘Objective To evaluate the early and mid-term results of endovascular repair for acute and chronic type B aortic dissection, and to compare the clinical outcomes between the 2 groups. Methods From May 2002 to December 2006, 50 patients with type B aortic dissection were treated by endovascular stent-graft. There were 23 patients in the acute aortic dissection (AAD) group and 27 patients in the chronic aortic dissection (CAD) group. All patients were followed up from 1 to 54 months (average, 17±16 months).The immediate and follow-up clinical outcomes were documented and compared between the 2 groups. Results Placement of endovascular stent-grafts across the primary entry tears was technically successful in all 50 patients. Compared to the CAD group, the AAD group had a higher percentage of pleural effusion (17.4% vs. 0%, P=0.04) and visceral /leg ischemia (26.1% vs 3.7%, P=0.04). Procedure related complications, including endoleak and post-implantation syndrome, occurred more frequently in the AAD group than in the CAD group (21.7% vs 3.7% and 30.4% vs 11.1%, respectively; P=0.08 and P=0.04). Kaplan–Meier analysis showed no difference in the survival rate at 4 years between the 2 groups (86.4% vs 92.3%, P=0.42 by log-rank test). However, the event-free survival rate was higher in patients with chronic dissection than in patients with acute aortic dissection(96.2% vs 73.9%; P=0.02 by log-rank test). Conclu- sions Endovascular repair with stent-graft was safe and effective for the treatment of both acute and chronic type B aortic dissection. However, both immediate and long term major complications occurred more frequently in patients with acute dissection than in those with chronic dissection. | Quanming Jing Yaling Han Xiaozheng Wang Jie Deng Bo Luan Hongxu Jin Xiaojiang Liu Fei Li Ying Liu | 2007 | Journal of Geriatric Cardiology2007，4，2： | 2 |
| 15 | Typhoon storm surge ensemble forecast based on GPU technique显示文摘The accuracy of typhoon forecasts plays an important role in the prediction of storm surges.The uncertainty of a typhoon’s intensity and track means it is necessary to use an ensemble model to predict typhoon storm surges.A hydrodynamic model,which is operational at the National Marine Environmental Forecasting Center,is applied to conduct surge simulations for South China coastal areas using the best track data with parametric wind and pressure models.The results agree well with tidal gauge observations.To improve the calculation efficiency,the hydrodynamic model is modified using CUDA Fortran.The calculation results are almost the same as those from the original model,but the calculation time is reduced by more than 99%.A total of 150 typhoon cases are generated by combining 50 typhoon tracks from the European Centre for Medium-Range Weather Forecasts with three possible typhoon intensity forecasts.The surge ensembles are computed by the improved hydrodynamic model.Based on the simulated storm surges for the different typhoon cases,ensemble and probability forecast products can be provided.The mean ensemble results and probability forecast products are shown to agree well with the observed storm surge caused by Typhoon Mangkhut.The improved model is highly suitable for ensemble numerical forecasts,providing better forecast products for decision-making,and can be easily implemented to run on regular workstations. | Qiuxing Liu Jinrong Jiang Fujiang Yu Changkuan Zhang Jianxi Dong Xiaojiang Song Yuzhu Wang | 2020 | Acta Oceanologica Sinica2020，39，5： | 1 |
