| 1 | Human parvovirus B19-associated early postoperative acquired pure red cell aplasia in simultaneous pancreas-kidney transplantation:A case report显示文摘BACKGROUND Acquired pure red cell aplasia(aPRCA)related to human parvovirus B19(HPV B19)is rarely reported in simultaneous pancreas-kidney transplantation(SPKT)recipients;there has yet to be a case report of early postoperative infection.In this current study,we report the case of a Chinese patient who experienced the disease in the early postoperative period.CASE SUMMARY A 63-year-old man,with type 2 diabetes and end-stage renal disease,received a brain dead donor-derived SPKT.Immunosuppression treatment consisted of tacrolimus,prednisone,enteric-coated mycophenolate sodium(EC-MPS),and thymoglobulin combined with methylprednisolone as induction.The hemoglobin(Hb)level declined due to melena at postoperative day(POD)3,erythropoietinresistant anemia persisted,and reticulocytopenia was diagnosed at POD 20.The bone marrow aspirate showed decreased erythropoiesis and the presence of giant pronormoblasts at POD 43.Metagenomic next-generation sequencing(mNGS)of a blood sample identified HPV B19 infection at POD 66.EC-MPS was withdrawn;three cycles of intravenous immunoglobulin(IVIG)infusion therapy were administered;and tacrolimus was switched to cyclosporine.The HPV B19-associated aPRCA resolved completely and did not relapse within the 1-year follow-up period.The diminution in mNGS reads was correlated with Hb and reticulocyte count improvements.CONCLUSION HPV B19-associated aPRCA can occur at an early period after SPKT.An effective therapy regimen includes IVIG infusion and adjustment of the immunosuppressive regimen.Moreover,mNGS can be used for the diagnosis and to reflect disease progression. | Hui Wang Ying-Xin Fu Wen-Li Song Zhen Wang Gang Feng Jie Zhao Ye-Qi Nian Yu Cao | 2021 | World Journal of Clinical Cases2021，9，8： | 2 |

| 3 | Predicting impact forces on pipelines from deep-sea fluidized slides:A comprehensive review of key factors显示文摘Deep-sea pipelines play a pivotal role in seabed mineral resource development,global energy and resource supply provision,network communication,and environmental protection.However,the placement of these pipelines on the seabed surface exposes them to potential risks arising from the complex deep-sea hydrodynamic and geological environment,particularly submarine slides.Historical incidents have highlighted the substantial damage to pipelines due to slides.Specifically,deep-sea fluidized slides(in a debris/mud flow or turbidity current physical state),characterized by high speed,pose a significant threat.Accurately assessing the impact forces exerted on pipelines by fluidized submarine slides is crucial for ensuring pipeline safety.This study aimed to provide a comprehensive overview of recent advancements in understanding pipeline impact forces caused by fluidized deep-sea slides,thereby identifying key factors and corresponding mechanisms that influence pipeline impact forces.These factors include the velocity,density,and shear behavior of deep-sea fluidized slides,as well as the geometry,stiffness,self-weight,and mechanical model of pipelines.Additionally,the interface contact conditions and spatial relations were examined within the context of deep-sea slides and their interactions with pipelines.Building upon a thorough review of these achievements,future directions were proposed for assessing and characterizing the key factors affecting slide impact loading on pipelines.A comprehensive understanding of these results is essential for the sustainable development of deep-sea pipeline projects associated with seabed resource development and the implementation of disaster prevention measures. | Xingsen Guo Ning Fan Defeng Zheng Cuiwei Fu Hao Wu Yanjun Zhang Xiaolong Song Tingkai Nian | 2024 | International Journal of Mining Science and Technology2024，34，2： | 0 |
| 4 | Suture ligation for submucosal hemostasis during hand-sewn sideto-side duodeno-ileostomy in simultaneous pancreas and kidney transplantation显示文摘BACKGROUND Enteric anastomotic(EA)bleeding is a potentially life-threatening surgical complication associated with enteric anastomosis during simultaneous pancreas and kidney transplantation(SPKT).AIM To investigate whether suture ligation(SL)for submucosal hemostasis during hand-sewn enteric anastomosis could decrease the morbidity of early EA bleeding in SPKT.METHODS We compared the outcomes of 134 patients classified into SL(n=44)and no SL(NSL)groups(n=90).This study adheres to the declarations of Istanbul and Helsinki and all donors were neither paid nor coerced.RESULTS During the first postoperative week,the EA bleeding rate in the SL group was lower than that in the NSL group(2.27%vs 15.56%;P=0.021);no relationship was found between EA bleeding and donor age,mean pancreatic cold ischemia time,platelet count,prothrombin time international normalized rate,activated partial thromboplastin time,and thrombin time.Anastomotic leakage was observed in one case in the SL group at postoperative day(POD)14 and in one case at POD 16 in the NSL group(P=0.754).No significant difference was found between the two groups in the patient survival,pancreas graft survival,or kidney graft survival.CONCLUSION SL for submucosal hemostasis during hand-sewn enteric anastomosis in SPKT can decrease the morbidity of early EA bleeding without increasing the anastomotic leakage rate. | Hui Wang Ying-Xin Fu Wen-Li Song Chun-Bai Mo Gang Feng Jie Zhao Guang-Hui Pei Xiao-Feng Shi Zhen Wang Yu Cao Ye-Qi Nian Zhong-Yang Shen | 2021 | World Journal of Gastrointestinal Surgery2021，13，9： | 0 |
| 5 | STUDY ON THE STABILITY AND STACKING INTERACTION EFFECT OF THE TERNARY M(Ⅱ)(ATP)AND PYRIDINE-LIKE LIGANDS显示文摘The stabilities of the complexes of three pyridine-like ligandswith M(II)(ATP)2- and M(II)(M=Ni,Co)were studied by spectrophotometryand by comparing the stability constants of the ternary complexes withthese of the binary complexes.A stacking interaction between the pyridinering and the purine ring of ATP is indicated.The general existence of thestacking interaction encourages us to interpret the antitumor mechanism ofa new class of antitumor drugs. | Bin SONG Jie ZHANG Fu Hai WU Liang Nian JI Biotechnology Research Center,Chemistry Department Zhongshan University,Guangzhou 510275 | 1993 | Chinese Chemical Letters1993，4，12： | 0 |
| 6 | TERNARY COMPLEXES OF Cu(ATP)AND HETEROAROMATIC N BASE-ISOQUINOLINE AND BENZIMIDAZOLE:STABILITY CONSTANT AND STACKING EFFECT显示文摘The stability constants of the binary complexes ofCu2+ with isoquinoline and benzimidazole as well as the ternarycomplexes of Cu(ATP)with the same ligands have been measuredin aqueous solution spectrophotometrically and a strongstacking interaction between the heteroaromatic ring of theligands and the purine moiety of ATP has been found.The factof this stacking interaction is much stronger than that in thesystems of Cu(ATP)with pyridine and imidazole shows thatthe stacking interaction increases with the size of theheteroaromatic ring of the ligands. | Fu Hai WU Bin SONG Liang Nian JI Biotechnology Research Center,Zhongshan University Guangzhou 510275 | 1993 | Chinese Chemical Letters1993，4，9： | 0 |
