| 1 | Key residues of the receptor binding motif in the spike protein of SARS-CoV-2 that interact with ACE2 and neutralizing antibodies显示文摘Coronavirus disease 2019(COVID-19),caused by the novel human coronavirus SARS-CoV-2,is currently a major threat to public health worldwide.The viral spike protein binds the host receptor angiotensin-converting enzyme 2(ACE2)via the receptor-binding domain(RBD),and thus is believed to be a major target to block viral entry.Both SARS-CoV-2 and SARS-CoV share this mechanism.Here we functionally analyzed the key amino acid residues located within receptor binding motif of RBD that may interact with human ACE2 and available neutralizing antibodies.The in vivo experiments showed that immunization with either the SARS-CoV RBD or SARS-CoV-2 RBD was able to induce strong clade-specific neutralizing antibodies in mice;however,the cross-neutralizing activity was much weaker,indicating that there are distinct antigenic features in the RBDs of the two viruses.This finding was confirmed with the available neutralizing monoclonal antibodies against SARS-CoV or SARS-CoV-2.It is worth noting that a newly developed SARS-CoV-2 human antibody,HA001,was able to neutralize SARS-CoV-2,but failed to recognize SARS-CoV.Moreover,the potential epitope residues of HA001 were identified as A475 and F486 in the SARS-CoV-2 RBD,representing new binding sites for neutralizing antibodies.Overall,our study has revealed the presence of different key epitopes between SARS-CoV and SARSCoV-2,which indicates the necessity to develop new prophylactic vaccine and antibody drugs for specific control of the COVID-19 pandemic although the available agents obtained from the SARS-CoV study are unneglectable. | Chunyan Yi Xiaoyu Sun Jing Ye Longfei Ding Meiqin Liu Zhuo Yang Xiao Lu Yaguang Zhang Liyang Ma Wangpeng Gu Aidong Qu Jianqing Xu Zhengli Shi Zhiyang Ling Bing Sun | 2020 | Cellular & Molecular Immunology2020，17，6： | 13 |
| 2 | Heat Transfer and Flow Resistance Characteristics of Helical Baffle Heat Exchangers with Twisted Oval Tube显示文摘To overcome the defect of the significant increase in pressure drop when the heat transfer performance of helical baffle heat exchanger is improved,a novel helical baffle heat exchanger with twisted oval tube is proposed.Numerical simulation was done to exhibit the shell side heat transfer and flow characteristics with CFD software Fluent.The field synergy principle was used to evaluate the shell side performance.The results show that the flow velocity distribution on the shell side of the spiral baffle heat exchanger is more uniform and the velocity near the tube wall increases in the range of research parameters,as the circular tube is replaced by a twisted elliptical tube with the same perimeter length.Moreover,the helical baffle heat exchanger with twisted oval tube has better field synergy of velocity and temperature gradient,velocity and pressure gradient.The helical baffle heat exchanger with helix angle of 15°has better performance than that of circular tube,and its heat transfer coefficient is improved about 3.3%and pressure drop is reduced by 17.1%–19.1%.Hence,the comprehensive heat transfer performance is improved by 21.5%–22.5%.When the helix angle is 20°,the comprehensive heat transfer performance is increased by 16.1%–18.0%with heat transfer coefficient improvement of 3.6%and pressure drop reduction of 13.9%–16.5%. | GU Xin ZHENG Zhiyang XIONG Xiaochao JIANG Erhui WANG Tongtong ZHANG Dongwei | 2022 | Journal of Thermal Science2022，31，2： | 2 |
| 3 | Characteristics of Fluid Flow and Heat Transfer in the Shell Side of the Trapezoidal-like Tilted Baffles Heat Exchanger显示文摘Periodic whole cross-section computation models are established for segmental baffle heat exchanger, shutter baffle heat exchanger, and trapezoid-like tilted baffle heat exchanger. The reliability of models is verified by comparing the simulated results to the results obtained from the Bell-Delaware method. Due to the orthogonal assembly of the baffles, the shell side fluid shows the twisty flow of trapezoid-like tilted baffle heat exchanger. The essential mechanism on disturbing flow and heat transfer enhancement is revealed by defining the non-dimensional factor η of the shell side fluid flow direction of heat exchanger and the field synergy principle. The results show that at the same Reynolds number, the shell side fluid convection heat transfer coefficient of trapezoid-like tilted baffle heat exchanger is 12.43%-24.33% and 6.71%-11.51% higher than those of segmental baffle heat exchanger and shutter baffle heat exchanger, respectively. The shell side fluid flow velocity field and the pressure gradient field of trapezoid-like tilted baffle heat exchanger and shutter baffle heat exchanger decreases compared with that of segmental baffle heat exchanger, so the shell side fluid flow resistance and pressure drop is increased; the shell side comprehensive performance of trapezoid-like tilted baffle heat exchanger is 5.85%-9.06% higher than that of segmental baffle heat exchanger, and 15.27%-23.28% higher than that of shutter baffle heat exchanger. In this study, a baffle structure with higher efficiency of the energy utilization for the heat exchanger is provided. | GU Xin ZHENG Zhiyang XIONG Xiaochao WANG Tongtong LUO Yuankun WANG Ke | 2018 | Journal of Thermal Science2018，27，6： | 2 |
| 4 | Protective humoral immunity in SARS-CoV-2 infected pediatric patients显示文摘After the rapid spread of SARS-CoV-2 in Wuhan,China,at the beginning of 2020,about 1.5 million confirmed cases and over 80,000 deaths have been reported around 200 countries and territories all over the world and the number continues to increase.However,we still have limited knowledge of this new coronavirus,especially the interaction between SARS-CoV-2 and our immune system. | Yaguang Zhang Jin Xu Ran Jia Chunyan Yi Wangpeng Gu Pengcheng Liu Xinran Dong Hao Zhou Bo Shang Shipeng Cheng Xiaoyu Sun Jing Ye Xuezhen Li Jia Zhang Zhiyang Ling Liyan Ma Bingbing Wu Mei Zeng Wenhao Zhou Bing Sun | 2020 | Cellular & Molecular Immunology2020，17，7： | 2 |
| 5 | Efficient drug delivery and anticancer effect of micelles based on vitamin E succinate and chitosan derivatives显示文摘Nanocarriers have emerged as a promising cancer drug delivery strategy.Multi-drug resistance caused by overexpression of multiple-drug excretion transporters in tumor cells is the major obstacle to successful chemotherapy.Vitamin E derivatives have many essential functions for drug delivery applications,such as biological components that are hydrophobic,stable,water-soluble enhancing compounds,and anticancer activity.In addition,vitamin E derivatives are also effective mitocan which can overcome multi-drug resistance by binding to P glycoproteins.Here,we developed a carboxymethyl chitosan/vitamin E succinate nano-micellar system(O-CMCTS-VES).The synthesized polymers were characterized by Fourier Transform IR,and 1H NMR spectra.The mean sizes of O-CMCTS-VES and DOX-loaded nanoparticles were around 177 nm and 208 nm.The drug loading contents were 6.1%,13.0%and 10.6%with the weight ratio of DOX to O-CMCTS-VES corresponding 1:10,2:10 and 3:10,and the corresponding EEs were 64.3%,74.5%and 39.7%.Cytotoxicity test,hemolysis test and histocompatibility test showed that it had good biocompatibility in vitro and in vivo.Drug release experiments implied good pH sensitivity and sustained-release effect.The DOX/O-CMCTS-VES nanoparticles can be efficiently taken up by HepG2 cancer cells and the tumor inhibition rate is up to 62.57%.In the in vivo study by using H22 cells implanted Balb/C mice,DOX/O-CMCTS-VES reduced the tumor volume and weight efficiently with a TIR of 35.58%.The newly developed polymeric micelles could successfully be utilized as a nanocarrier system for hydrophobic chemotherapeutic agents for the treatment of solid tumors. | Xiaotong Chen Junxiang Gu Le Sun Wenya Li Lili Guo Zhiyang Gu Litong Wang Yan Zhang Wangwang Zhang Baoqin Han Jing Chang | 2021 | Bioactive Materials2021，6，10： | 1 |
| 6 | HTR2A agonists play a therapeutic role by restricting ILC2 activation in papain-induced lung inflammation显示文摘Group 2 innate lymphoid cells(ILC2s)are a category of heterogeneous cells that produce the cytokines IL-5 and IL-13,which mediate the type 2 immune response.However,specific drug targets on lung ILC2s have rarely been reported.Previous studies have shown that type 2 cytokines,such as IL-5 and IL-13,are related to depression.Here,we demonstrated the negative correlation between the depression-associated monoamine neurotransmitter serotonin and secretion of the cytokines IL-5 and IL-13 by ILC2s in individuals with depression.Interestingly,serotonin ameliorates papain-induced lung inflammation by suppressing ILC2 activation.Our data showed that the serotonin receptor HTR2A was highly expressed on ILC2s from mouse lungs and human PBMCs.Furthermore,an HTR2A selective agonist(DOI)impaired ILC2 activation and alleviated the type 2 immune response in vivo and in vitro.Mice with ILC2-specific depletion of HTR2A(Il5^(cre/+)·Htr2a^(flox/flox)mice)abolished the DOI-mediated inhibition of ILC2s in a papain-induced mouse model of inflammation.In conclusion,serotonin and DOI could restrict the type 2 lung immune response,indicating a potential treatment strategy for type 2 lung inflammation by targeting HTR2A on ST2+ILC2s. | Zhishuo Wang Chenghua Yan Qizhen Du Yuying Huang Xuezhen Li Dan Zeng Ruizhi Mao Rama Krishna Gurram Shipeng Cheng Wangpeng Gu Lin Zhu Weiguo Fan Liyan Ma Zhiyang Ling Ju Qiu Dangsheng Li Enmei Liu Yaguang Zhang Yiru Fang Jinfang Zhu Bing Sun | 2023 | Cellular & Molecular Immunology2023，20，4： | 1 |
| 7 | Vitamin B6 regulates IL-33 homeostasis to alleviate type 2 inflammation显示文摘Interleukin-33(IL-33)is a crucial nuclear cytokine that induces the type 2 immune response and maintains immune homeostasis.The fine-tuned regulation of IL-33 in tissue cells is critical to control of the type 2 immune response in airway inflammation,but the mechanism is still unclear.Here,we found that healthy individuals had higher phosphate-pyridoxal(PLP,an active form of vitamin B6)concentrations in the serum than asthma patients.Lower serum PLP concentrations in asthma patients were strongly associated with worse lung function and inflammation.In a mouse model of lung inflammation,we revealed that PLP alleviated the type 2 immune response and that this inhibitory effect relied on the activity of IL-33.A mechanistic study showed that in vivo,pyridoxal(PL)needed to be converted into PLP,which inhibited the type 2 response by regulating IL-33 stability.In mice heterozygous for pyridoxal kinase(PDXK),the conversion of PL to PLP was limited,and IL-33 levels were increased in the lungs,aggravating type 2 inflammation.Furthermore,we found that the mouse double minute 2 homolog(MDM2)protein,an E3 ubiquitin-protein ligase,could ubiquitinate the N-terminus of IL-33 and sustain IL-33 stability in epithelial cells.PLP reduced MDM2-mediated IL-33 polyubiquitination and decreased the level of IL-33 through the proteasome pathway.In addition,inhalation of PLP alleviated asthma-related effects in mouse models.In summary,our data indicate that vitamin B6 regulates MDM2-mediated IL-33 stability to constrain the type 2 response,which might help develop a potential preventive and therapeutic agent for allergy-related diseases. | Songling Zhu Shufen Zhong Kebin Cheng Li-Sha Zhang Jiu-wu Bai Zu Cao Su Wang Wen Chen Shipeng Cheng Liyan Ma Zhiyang Ling Yuying Huang Wangpeng Gu Xiaoyu Sun Chunyan Yi Meng Zhao Shuo Liang Jin-Fu Xu Bing Sun Yaguang Zhang | 2023 | Cellular & Molecular Immunology2023，20，7： | 1 |
| 8 | A SARS-CoV-2 antibody retains potent neutralization against Omicron by targeting conserved RBM residues显示文摘The newly emerged Omicron(B.1.1.529)variant of SARS-CoV-2 is quickly overtaking the Delta variant and becoming the dominant strain around the world due to its enhanced transmissibility and high immune escape potential[1,2].Compared to the Wuhan strain,the Omicron variant carries 37 spike mutations,of which 15 are within the receptor-binding domain(RBD)(Fig.1A).A high mutation rate is associated with remarkable resistance to current vaccines and RBD-specific antibody therapeutics[2,3,4]. | Chunyan Yi Zhiyang Ling Xiao Lu Yadong Fu Zhuo Yang Sonam Wangmo Shuangfeng Chen Yaguang Zhang Liyan Ma Wangpeng Gu Hongzhou Lu Xiaoyu Sun Bing Sun | 2022 | Cellular & Molecular Immunology2022，19，5： | 1 |
| 9 | N-carboxymethyl chitosan/sodium alginate composite hydrogel loading plasmid DNA as a promising gene activated matrix for in-situ burn wound treatment显示文摘Improving the degree of vascularization through the regulation of wound microenvironment is crucial for wound repair.Gene activated matrix(GAM)technology provides a new approach for skin regeneration.It is a local gene delivery system that can not only maintain a moist environment,but also increase the concentration of local active factors.For this purpose,we fabricated the mVEGF165/TGF-β1 gene-loaded N-carboxymethyl chitosan/sodium alginate hydrogel and studied its effect on promoting deep second degree burn wound repair.The average diameter of the hydrogel pores was 100μm and the porosity was calculated as 50.9%.SEM and CLSM images showed that the hydrogel was suitable for cell adhesion and growth.The NS-GAM could maintain continuous expression for at least 9 days in vitro,showing long-term gene release and expression effect.Deep second-degree burn wound model was made on the backs of Wistar rats to evaluate the healing effect.The wounds were healed by day 22 in NS-GAM group with the prolonged high expression of VEGF and TGF-β1 protein.A high degree of neovascularization and high expression level of CD34 were observed in NS-GAM group in 21 days.The histological results showed that NS-GAM had good tissue safety and could effectively promote epithelialization and collagen regeneration.These results indicated that the NS-GAM could be applied as a promising local gene delivery system for the repair of deep second-degree burn wounds. | Litong Wang Le Sun Zhiyang Gu Wenya Li Lili Guo Saibo Ma Lan Guo Wangwang Zhang Baoqin Han Jing Chang | 2022 | Bioactive Materials2022，7，9： | 1 |

| 11 | Deep learning enhanced lithium-ion battery nonlinear fading prognosis显示文摘With the assistance of artificial intelligence,advanced health prognosis technique plays a critical role in the lithium-ion(Li-ion) batteries management system.However,conventional data-driven early aging prediction exhibited dramatic drawbacks,i.e.,volatile capacity nonlinear fading trajectories create obstacles to the accurate multistep ahead prediction due to the complex working conditions of batteries.Herein,a novel deep learning model is proposed to achieve a universal and accurate Li-ion battery aging prognosis.Two battery datasets with various electrode types and cycling conditions are developed to validate the proposed approaches.Knee-point probability(KPP),extracted from the capacity loss curve,is first proposed to detect knee points and improve state-of-health(SOH) predictive accuracy,especially during periods of rapid capacity decline.Using one-cycle data of partial raw voltage as the model input,the SOH and KPP can be simultaneously predicted at multistep ahead,whereas the conventional method showed worse accuracy.Furthermore,to explore the underlying characteristics among various degradation tendencies,an online model update strategy is developed by leveraging the adversarial adaptationinduced transfer learning technique.This work gains new sights into the comprehensive Li-ion battery management and prognosis framework through decomposing capacity degradation trajectories and adversarial learning on the unlabeled samples. | Shanling Ji Jianxiong Zhu Zhiyang Lyu Heze You Yifan Zhou Liudong Gu Jinqing Qu Zhijie Xia Zhisheng Zhang Haifeng Dai | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 12 | Tuning the exciton binding energy of covalent organic frameworks for efficient photocatalysis显示文摘Owing to the large exciton binding energy(>100 meV)of most organic materials,the process of exciton dissociation into free electrons and holes is seriously hindered,which plays a key role in the photocatalytic system.In this study,a series of chalcogen(S,Se)-substituted mesoporous covalent organic frameworks(COFs)have been synthesized for enhanced photocatalytic organic transformations.Photoelectrochemical measurements indicate that the introduction of semi-metallic Se atom and the enlargement of conjugation degree can not only reduce the exciton binding energy accelerating the charge separation,but also reduce the band gap of COFs.As a result,the COF-NUST-36 with the lowest exciton binding energy(39.5 meV)shows the highest photocatalytic performance for selective oxidation of amines(up to 98%Conv.and 97.5%Sel.).This work provides a feasible method for designing COFs with high photocatalytic activity by adjusting exciton binding energy. | Zhangjie Gu Zhen Shan Yulan Wang Jinjian Wang Tongtong Liu Xiaoming Li Zhiyang Yu Jian Su Gen Zhang | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 13 | Adaptive Barebones Salp Swarm Algorithm with Quasi-oppositional Learning for Medical Diagnosis Systems: A Comprehensive Analysis显示文摘The Salp Swarm Algorithm(SSA)may have trouble in dropping into stagnation as a kind of swarm intelligence method.This paper developed an adaptive barebones salp swarm algorithm with quasi-oppositional-based learning to compensate for the above weakness called QBSSA.In the proposed QBSSA,an adaptive barebones strategy can help to reach both accurate convergence speed and high solution quality;quasi-oppositional-based learning can make the population away from traping into local optimal and expand the search space.To estimate the performance of the presented method,a series of tests are performed.Firstly,CEC 2017 benchmark test suit is used to test the ability to solve the high dimensional and multimodal problems;then,based on QBSSA,an improved Kernel Extreme Learning Machine(KELM)model,named QBSSA–KELM,is built to handle medical disease diagnosis problems.All the test results and discussions state clearly that the QBSSA is superior to and very competitive to all the compared algorithms on both convergence speed and solutions accuracy. | Jianfu Xia Hongliang Zhang Rizeng Li Zhiyan Wang Zhennao Cai Zhiyang Gu Huiling Chen Zhifang Pan | 2022 | Journal of Bionic Engineering2022，19，1： | 0 |
| 14 | Effects on the STAT3-shRNA in Non-Small-Cell Lung Cancer Therapy: Design, Induction of Apoptosis, and Conjugation with Chitosan-Based Gene Vectors显示文摘STAT3 plays a particularly important role in several cancer-related signal transduction pathways.Silencing STAT3 via RNA interference or small molecule inhibitors induces the apoptosis of tumor cells,thereby inhibiting the growth of the tumors.In this study,short-hairpin RNA sequences targeting the STAT3 genes were designed,synthesized,and then connected to pGPU6/GFP/Neo plasmids as the shRNA-expression vectors.The expression of STAT3-shRNA was analyzed by real-time PCR,western blotting,and cell apoptosis assay to study the growth and apoptosis of the cells.Then,the effect of STAT3 knockdown on the NCI-H1650 cells was studied in a tumor mouse model.The results revealed that,after an in vitro transfection,the proliferation of NCI-H1650 cells was inhibited,and the cells were induced to apoptosis.The mRNA and protein expression levels of STAT3 were downregulated in the STAT3-shRNA group.In vivo,the tumor mass and volume in the STAT3-shRNA group were significantly lower than in the other two groups.Both the in vivo and in vitro results demonstrated a long-period inhibiting effect on NSCLC,especially in vivo,when the tumor inhibition rate could reach 50%in the STAT3-shRNA group,which is an exciting outcome.Moreover,the study of the conjugation of STAT3-shRNA and chitosan-based vectors revealed that they could be combined steadily with good cytocompati-bility and transfection efficiency.These results together provide convincing evidence for the application of STAT3-shRNA used in the treatment of non-small lung cancer,which could be a promoting prospect for the development of gene therapy. | ZHANG Wangwang ZHANG Yan JIANG Zhiwen SUN Le WANG Litong GU Zhiyang LI Wenya GUO Lili CHEN Xiaotong ZHANG Haibin HAN Baoqin CHANG Jing | 2021 | Journal of Ocean University of China2021，20，5： | 0 |
| 15 | TRIM34 attenuates colon inflammation and tumorigenesis by sustaining barrier integrity显示文摘Loss of the colonic inner mucus layer leads to spontaneously severe colitis and colorectal cancer.However,key host factors that may control the generation of the inner mucus layer are rarely reported.Here,we identify a novel function of TRIM34 in goblet cells(GCs)in controlling inner mucus layer generation.Upon DSS treatment,TRIM34 deficiency led to a reduction in Muc2 secretion by GCs and subsequent defects in the inner mucus layer.This outcome rendered TRIM34-deficient mice more susceptible to DSS-induced colitis and colitis-associated colorectal cancer.Mechanistic experiments demonstrated that TRIM34 controlled TLR signaling-induced Nox/Duox-dependent ROS synthesis,thereby promoting the compound exocytosis of Muc2 by colonic GCs that were exposed to bacterial TLR ligands.Clinical analysis revealed that TRIM34 levels in patient samples were correlated with the outcome of ulcerative colitis(UC)and the prognosis of rectal adenocarcinoma.This study indicates that TRIM34 expression in GCs plays an essential role in generating the inner mucus layer and preventing excessive colon inflammation and tumorigenesis. | Qiaoshi Lian Shanshan Yan Qi Yin Chenghua Yan Wanwei Zheng Wangpeng Gu Xinhao Zhao Weiguo Fan Xuezhen Li Liyan Ma Zhiyang Ling Yaguang Zhang Jie Liu Jinsong Li Bing Sun | 2021 | Cellular & Molecular Immunology2021，18，2： | 0 |
| 16 | Visual acuity is correlated with ischemia and neurodegeneration in patients with early stages of diabetic retinopathy显示文摘Purpose:We investigated the effects of retinal ischemia,neurodegeneration,and subclinical edema on best-corrected visual acuity(BCVA)in the early stages of diabetic retinopathy(DR).Methods:Ischemia was evaluated by the microvascular parameters measured by optical coherence tomography angiography.Neurodegeneration and subclinical edema were identified by the intraretinal layer thickness obtained by optical coherence tomography.Eyes with nonproliferative diabetic retinopathy(n=132)from 89 patients were analyzed.Eyes were classified as having normal BCVA(n=88[66.7%],Snellen equivalent≥20/20)or decreased BCVA(n=44[33.3%],Snellen equivalent<20/20).The prevalence of ischemia,neurodegeneration,and subclinical edema was explored in patients with and without decreased BCVA,and correlations between BCVA and these pathological pathways were determined.Results:Vessel density in the deep retinal capillary plexus(DRCP)and thickness of ganglion cell layer plus inner plexiform layer(GCL-IPL)were significantly lower in eyes with decreased BCVA compared with eyes with normal BCVA(both P<0.05).In the final multiple regression predictive model,age,DRCP vessel density,and GCL-IPL thickness(all P≤0.044)were predictors of BCVA.DRCP vessel density and GCL-IPL thickness have an interactive effect on visual acuity.The proportions of ischemia and neurodegeneration were significantly higher in eyes with decreased BCVA than in eyes with normal BCVA(P=0.001 and P=0.004,respectively).Conclusion:During the natural course of the early stages of DR,ischemia and neurodegeneration were the main disease pathways associated with visual acuity,and the mechanisms varied among patients. | Jin Li Yue Zhou Feng Chen Yingzi Li Rong Zhou Chaoming Wu Huankai Yu Zhiyang Lin Ce Shi Gu Zheng Yilei Shao Qi Chen Fan Lu Meixiao Shen | 2021 | Eye and Vision2021，8，1： | 0 |
| 17 | Balloon-occluded retrograde transvenous obliteration with lauromacrogol sclerosant foam for gastric varices显示文摘Objectives:To evaluate the safety and efficacy of balloon-occluded retrograde transvenous obliteration(BRTO)using lauromacrogol sclerosant foam for gastric varices(GVs)with gastrorenal venous shunts.Methods:Data of GV patients treated with BRTO using lauromacrogol sclerosant foam in 2016–2020 were retrospectively analyzed along with procedural success rate,complications,and follow-up efficacy.Results:A total of 31 patients were treated with BRTO.The sclerosant foam was prepared by mixing iodinated oil,lauromacrogol,and air at a 1:2:3 ratio.The BRTO procedure was successfully completed in 93.5%of patients.One patient was allergic to the lauromacrogol injection.A mild postoperative fever occurred in three patients.One patient experienced grand mal seizures after the procedure.There was no significant difference in the median Child-Turcotte-Pugh scores before versus after BRTO.Complete GV resolution was observed in 93.1%of patients.One patient underwent endoscopic treatment for the development of high-risk esophageal varices.Another patient underwent transjugular intrahepatic portosystemic shunt placement for the aggravation of ascites.Conclusions:Lauromacrogol sclerosant foam is safe and effective in patients undergoing BRTO for GV. | Zhiyang Wu Wei Wu Cheng Tao Qin Liu Wenchang Li Qinbing Wang Wei Huang Junwei Gu Xiaoyan Fei Zhongmin Wang Xiaoyi Ding | 2022 | Journal of Interventional Medicine2022，5，3： | 0 |
