| 1 | From concept to reality-A review to the primary test stand and its preliminary application in high energy density physics显示文摘Pulsed power technology,whereas the electrical energy stored in a relative long period is released in much shorter timescale,is an efficient method to create high energy density physics(HEDP)conditions in laboratory.Around the beginning of this century,China Academy of Engineering Physics(CAEP)began to build some experimental facilities for HEDP investigations,among which the Primary Test Stand(PTS),a multi-module pulsed power facility with a nominal current of 10 MA and a current rising time~90 ns,is an important achievement on the roadmap of the electro-magnetically driven inertial confinement fusion(ICF)researches.PTS is the first pulsed power facility beyond 10 TW in China.Therefore,all the technologies have to be demonstrated,and all the engineering issues have to be overcome.In this article,the research outline,key technologies and the preliminary HEDP experiments are reviewed.Prospects on HEDP research on PTS and pulsed power development for the next step are also discussed. | Jianjun Deng Weiping Xie Shuping Feng Meng Wang Hongtao Li Shengyi Song Minghe Xia Ji Ce An He Qing Tian Yuanchao Gu Yongchao Guan Bin Wei Xianbin Huang Xiaodong Ren Jiakun Dan Jing Li Shaotong Zhou Hongchun Cai Siqun Zhang Kunlun Wang Qiang Xu Yujuan Wang Zhaohui Zhang Guilin Wang Shuai Guo Yi He Yiwei Zhou Zhanji Zhang Libing Yang Wenkang Zou | 2016 | Matter and Radiation at Extremes2016，1，1： | 19 |
| 2 | Wnt/β-catenin signaling is involved in the Icariin induced proliferation of bone marrow mesenchymal stem cells显示文摘OBJECTIVE: To investigate the effect of icariin on proliferation of bone marrow mesenchymal stem cells(BMSCs) in Sprague-Dawley(SD) rats.METHODS: BMSCs were obtained from SD rat bone marrow with differential time adherent method. Its characteristic was identified through differentiation cell surface antigens and the multi-lineage(osteo/adipo/chondo) differentiation potential. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) method and 5-Bromo-2-Deoxyuridine(Brd U) incorporation were applied to detect the effect of icariin on BMSCs proliferation.Flow cytometry was used to detect proliferation in-dex of BMSCs. The m RNA level and the distribution of β-catenin were evaluated by Real-time Polymerase Chain Reaction(PCR) and Immunofluorescent staining respectively. Western blot was used to detect protein expression levels of β-catenin, glycogen synthase kinase-3 beta(GSK-3β), phospho-glycogen synthase kinase-3 beta(p GSK-3β)and cyclin D1.RESULTS: Icariin promoted BMSCs proliferation at the concentration of 0.05-2.0 mg/L. The percentage of Brd U positive cells of BMSCs was increased from40.98% to 70.42%, and the proliferation index value was increased from 8.9% to 17.5% with the treatment of 0.05 mg/L icariin, which significance values were both less than 0.05. Compared with the control group, total and nuclear β-catenin proteins, as well as β-catenin m RNA expression, were all increased with icariin treatment. Meanwhile, the phosphorylation level of GSK-3β and cyclin D1 protein expressions were also increased in BMSCs with icariin treatment.CONCLUSION: The findings of the present study demonstrated that low dosage of icariin could promote BMSCs proliferation. The activation of Wnt/β-catenin pathways was involved in this process. | Fu Shuping Yang Li Hong Hao Zhang Ronghua | 2016 | Journal of Traditional Chinese Medicine2016，36，3： | 18 |
| 3 | Polysaccharides from Tricholoma matsutake and Lentinus edodes enhance 5-fluorouracil-mediated H22 cell growth inhibition显示文摘OBJECTIVE: Few studies have investigated the effects produced by combinations of polysaccharides and chemotherapeutic drugs in cancer treatment.We hypothesized that a combinationo fpolysaccha rides(COP) from Lentinus edodes and Tricholoma matsutake would improve the efficacy of 5-fluorouracil(5-FU)-mediated inhibition of H22 cell growth.METHODS: Mice were injected H22 cells and then treated with either 5-FU, polysaccharides from Tricholoma matsutake(PTM), polysaccharides from Lentinus edodes(PL), PTM+PL, 5-FU+PTM, 5-FU+PL, or 5-FU+COP. The tumor weight and volume,and splenic CD4 + and CD8 + T cell frequencies,were determined. Additionally, splenic natural killer(NK) cell and cytotoxic Tlymphocyte (CTL) activities were assessed and the serum levels of tumor necrosis factor-α(TNF-α),Interleukin-2(IL-2),and Interferon-γ (IFN-γ) were measured. 5-FU, PL, PTM, PTM+PL, 5-FU+PL, and 5-FU+PTM groups, mice treated with 5-FU+COP showed:(a)significantly reduced tumor weight and volume(P<0.05);(b) significantly higher serum levels ofTNF-α,IL-2, and IFN-γ(P<0.05);(c) significantly increased CD4+andCD8+Tcell frequencies in the spleen(P<0.05); and(d) significantly increased splenic NK cell and CTL activities(P<0.05). The tumor weight and volume in mice treated with 5-FU+PL or 5-FU+PTM were significantly reduced compared with mice treated with 5-FU alone(P<0.05). Serum levels of TNF-α, IL-2, and IFN-γ, frequencies of CD4 + and CD8+T cells in the spleen, and splenic NK and CTL activities were also significantly increased in mice treated with 5-FU+PL or 5-FU+PTM compared with mice treated with 5-FU alone (P<0.05).CONCLUSION: Polysaccharides from Lentinus edodes and Tricholoma matsutake could enhance the efficacy of 5-FU-mediated H22 cell growth inhibition. | Ming Ren Lingyan Ye Xiaoshi Hao Zhixing Ren Shuping Ren Kun Xu Juan Li | 2014 | Journal of Traditional Chinese Medicine2014，34，3： | 15 |
| 4 | Polygenetic Mineralization of the Early ProterozoicTongkuangyu Metaporphyry Copper Deposit inthe Zhongtiao Mountains,Shanxi Province显示文摘The Tongkuangyu metaporphyry copper deposit formed in the Early Proterozoic is tectonically located in the northern part of the Zhongtiao X -type palaeorift depression, on the southern margin of the North China platform. The genesis of the deposit has long been a hot subject of research of geologists working on mineral deposits. By means of the protolith reconstruction and fluid inclusion and isotope studies of host rocks of the deposits, the authors hold that this deposit is the product of combined exogenic, endogenic and metamorphic processes. Its formation mainly involved the following four stages: (1) the stage of formation of Mg- and Fe-rich tuffaceous variegated cupriferous sand-shale and K-rich biomodal volcanic rocks; (2) the early stage of formation of the metaporphyry copper deposit; (3) the stage of formation of the metaporphyry copper deposit; and (4) the stage of reworking of the metaporphyry copper deposit. | CHEN Wenming ZHANG Chengxin LU Jiren DANG Zefa LI Shuping CUI Wenbin NING Yuan | 1998 | Acta Geologica Sinica(English Edition)1998，72，2： | 7 |
| 5 | Preparation and activity evaluation of NiMoB/-Al_2O_3 catalyst by liquid-phase furfural hydrogenation显示文摘Amorphous MoNiB/ -Al 2 O 3 alloy catalysts were prepared by reducing NiCl 2 ·6H 2 O and (NH 4 ) 6 Mo 7 O 24 ·4H 2 O supported on -Al 2 O 3 with NaBH 4 as reducing agent. Using liquid-phase hydro-genation of furfural (FFR) as a probe reaction, the activity of MoNiB/ -Al 2 O 3 was examined. Compared to NiB and NiMoB, NiMoB/ -Al 2 O 3 exhibited excellent activity and selectivity towards furfuryl alcohol (FFA). After reaction for 3.0 h at 80 ℃ and 5.0 MPa in methanol, FFR conversion reached 99% with FFA yield of 91%. The effects of doping amount of Mo and calcination temperature before NaBH 4 reduction on hydrogenation activity were also investigated. The optimum Mo/Ni atom ratio and calcination temperature were found to be 1:7 and 300 ℃, respectively. XRD patterns and SEM images indicated that NiMoB over the surface of -Al 2 O 3 was amorphous and highly dispersed, which was responsible for the high thermal stability of the title catalyst. | Shuqin Wei Hongyou Cui Jinghua Wang Shuping Zhuo Weiming Yi Lihong Wang Zhihe Li | 2011 | Particuology2011，9，1： | 7 |
| 6 | Sedimentation Rate Rhythms:Evidence from Filling of the Tarim Basin,Northwest China显示文摘Variations of sedimentation rate within a basin over geologic time are a time series that can be filtered into several cyclic wave curves. Based on back-stripping and the empirical mode decomposition method, the cores from 14 wells in the Tarim Basin were selected to do filtering analysis. Four cycles or quasi-cycles(33 Ma, 64.4 Ma, 103.6 Ma, and 224 Ma) were obtained. Among these, the 33 Ma period, which was related to the internal earth activity, an external force, or a combination of the two, was the most obvious. The 64.4 Ma period corresponded to the solar system crossing the galaxy plane or the periodic melting of inner-earth material. The 103.6 Ma period was related with plate collisional tectonism around the Tarim Plate. The 224 Ma period was related to one galaxy year and may also be related to the aesthenospherical convection cycle. | CHEN Shuping JIN Zhijun WANG Yi ZHOU Ziyong LI Jingchang YANG Weili | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 6 |
| 7 | Text Detection in Natural Scene Images Using Morphological Component Analysis and Laplacian Dictionary显示文摘Text in natural scene images usually carries abundant semantic information. However, due to variations of text and complexity of background, detecting text in scene images becomes a critical and challenging task. In this paper, we present a novel method to detect text from scene images. Firstly, we decompose scene images into background and text components using morphological component analysis(MCA), which will reduce the adverse effects of complex backgrounds on the detection results.In order to improve the performance of image decomposition,two discriminative dictionaries of background and text are learned from the training samples. Moreover, Laplacian sparse regularization is introduced into our proposed dictionary learning method which improves discrimination of dictionary. Based on the text dictionary and the sparse-representation coefficients of text, we can construct the text component. After that, the text in the query image can be detected by applying certain heuristic rules. The results of experiments show the effectiveness of the proposed method. | Shuping Liu Yantuan Xian Huafeng Li Zhengtao Yu | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，1： | 6 |
| 8 | Epidemiology of urticaria in China:a population-based study显示文摘Background:Urticaria is a common skin disease characterized by episodes of wheals,and it has a negative effect on patients’quality of life.Large-scale population-based epidemiological studies of urticaria are scarce in China.The aim of this survey was to determine the prevalence,clinical forms,and risk factors of urticaria in the Chinese population.Methods:This survey was conducted in 35 cities from 31 provinces,autonomous regions,and municipalities of China.Two to three communities in each city were selected in this investigation.Participants completed questionnaires and received dermatological examinations.We analyzed the prevalence,clinical forms,and risk factors of urticaria.Results:In total,44,875 questionnaires were distributed and 41,041 valid questionnaires were collected(17,563 male and 23,478 female participants).The lifetime prevalence of urticaria was 7.30%,with 8.26%in female and 6.34%in male individuals(P<0.05).The point prevalence of urticaria was 0.75%,with 0.79%in female and 0.71%in male individuals(P<0.05).Concomitant angioedema was found in 6.16%of patients.Adults had a higher prevalence of urticaria than adolescents and children.Living in urban areas,exposure to pollutants,an anxious or depressed psychological status,a personal and family history of allergy,thyroid diseases,and Helicobacter pylori infection were associated with a higher prevalence of urticaria.Smoking was correlated with a reduced risk of urticaria.Conclusion:This study demonstrated that the lifetime prevalence of urticaria was 7.30%and the point prevalence was 0.75%in the Chinese population;women had a higher prevalence of urticaria than men.Various factors were correlated with urticaria. | Jiaqing Li Dandan Mao Shuoshuo Liu Ping Liu Jing Tian Chenhong Xue Xiaojing Liu Ruiqun Qi Bingxue Bai Jianjun Nie Siqi Ye Yu Wang Yuye Li Qing Sun Juan Tao Shuping Guo Hong Fang Jianqin Wang Qiri Mu Quanzhong Liu Yan Ding Jianzhong Zhang | 2022 | Chinese Medical Journal2022，，11： | 6 |
| 9 | Denitrification Rate and Controlling Factors for Accumulated Nitrate in the Deep Subsoil of Intensive Farmlands: A Case Study in the North China Plain显示文摘Denitrification in subsoil(to a depth of 12 m) is an important mechanism to reduce nitrate(NO3^-) leaching into groundwater.However, regulating mechanisms of subsoil denitrification, especially those in the deep subsoil beneath the crop root zone, have not been well documented. In this study, soil columns of 0–12 m depth were collected from intensively farmed fields in the North China Plain. The fields had received long-term nitrogen(N) fertilizer inputs at 0(N0), 200(N200) and 600(N600) kg N ha^-1 year^-1. Main soil properties related to denitrification, i.e., soil water content, NO3^-, dissolved organic carbon(DOC), soil organic carbon(SOC),pH, denitrifying enzyme activity(DEA), and anaerobic denitrification rate(ADR), were determined. Statistical comparisons among the treatments were performed. The results showed that NO3^- was more heavily accumulated in the entire soil profile of the N600 treatment, compared to the N0 and N200 treatments. The SOC, DOC, and ADR decreased with increasing soil depth in all treatments,whereas considerable DEA was observed throughout the subsoil. The long-term fertilizer rates affected ADR only in the upper 4 m soil layers. The ADRs in the N200 and N600 treatments were significantly correlated with DOC. Multiple regression analysis indicated that DOC rather than DEA was the key factor regulating denitrification beneath the root zone. Additional research is required to determine if carbon addition into subsoil can be a promising approach to enhance NO3^- denitrification in the subsoil and consequently to mitigate groundwater NO3^- contamination in the intensive farmlands. | YUAN Haijing QIN Shuping DONG Wenxu HU Chunsheng Kiril MANEVSKI LI Xiaoxin | 2019 | Pedosphere2019，29，4： | 5 |
| 10 | Atomic force microscopic observation on substructure of pollen exine in Cedrus deodara and Metasequoia glyptostroboides显示文摘The substructure of pollen exine in Cedrus deodara (Roxb.) Loud, and Metasequoia glyptostroboides Hu et Cheng has been examined with an atomic force microscope (AFM). The results indicate that the exine substructure units containing sporopollenin in two species are similar in shape, which are granular, but slightly different in size. In Cedrus the substructure unit of pollen exine appears to be 56-99 nm long and 42-74 nm wide, while in Metasequoia it appears to be 81-118 nm long and 43-98 nm wide. It has been observed that the subunits of pollen exine in Cedrus arranged tightly to form short-rod-like or spheroidal pollen exine units, several or more than ten of which formed an island-like structure. There are various spaces among these island-like structures which are interconnected to occupy the entire pollen exine. In Metasequoia, the subunits of pollen exine also arranged tightly with a distribution tendency of cluster of 3-10, however, no obvious boundary exists among these clusters.

| 11 | Multiple fields manipulation on nitride material structures in ultraviolet light-emitting diodes显示文摘As demonstrated during the COVID-19 pandemic,advanced deep ultraviolet(DUV)light sources(200–280 nm),such as AlGaN-based light-emitting diodes(LEDs)show excellence in preventing virus transmission,which further reveals their wide applications from biological,environmental,industrial to medical.However,the relatively low external quantum efficiencies(mostly lower than 10%)strongly restrict their wider or even potential applications,which have been known related to the intrinsic properties of high Al-content AlGaN semiconductor materials and especially their quantum structures.Here,we review recent progress in the development of novel concepts and techniques in AlGaNbased LEDs and summarize the multiple physical fields as a toolkit for effectively controlling and tailoring the crucial properties of nitride quantum structures.In addition,we describe the key challenges for further increasing the efficiency of DUV LEDs and provide an outlook for future developments. | Jinchai Li Na Gao Duanjun Cai Wei Lin Kai Huang Shuping Li Junyong Kang | 2021 | Light(Science & Applications)2021，10，7： | 4 |
| 12 | The investigation for the relationship among serum leptin, erythrocyte membrane Ca^(2+)-ATPase activity and hypertensive disorder complicating pregnancy显示文摘Objective: To study the significance of Leptin and the activity of erythrocyte membrane Ca2+-ATPase(EMCA) in the development of hypertensive disorder complicating pregnancy. Methods: Radioimmunoassay was used to test the level of serum Leptin,and the activity of EMCA was determined chemically in 38 pregnant women with hypertensive disorder complicating pregnancy and 36 normotensive pregnant women. Results: The level of serum Leptin in hypertensive disorder complicating pregnancy(gestational hypertension: 13.76 ± 3.46 ng/ml; preeclampsia:15.76 ± 5.47 ng/ml; eclampsia: 18.32 ± 6.38 ng/ml)was significantly higher than that in normotensive pregnant women(11.33 ± 2.93 ng/ml),respectively. The average EMCA activity of patients with hypertensive disorder complicating pregnancy(gestational hypertension:1.65 ± 0.24 μmol·pi/mg·h ; preeclampsia:1.37 ± 0.19 μ mol·pi/mg·h; eclampsia:1.12 ± 0.14 μ mol·pi/mg·h) was significantly lower than that of normotensive pregnant women(1.83 ± 0.38 μ mol·pi/mg·h),respectively. There was a negative correlation between the level of serum Leptin and the activity of RMCA in hypertensive disorder complicating pregnancy(r = -0.63). Conclusion: Inhibition of EMCA activity of erythrocyte in hypertensive disorder complicating pregnancy may increase cytoplasmic free calcium, which contributes to the development of hypertensive disorder complicating pregnancy. The negative correlation between the level of serum Leptin and the activity of EMCA, also suggested that serum Leptin and the activity of EMCA may play a role in the development of hypertensive disorder complicating pregnancy. | Chunfang Li Wenli Gou Xuelian Chen Shuping Zhang | 2007 | Journal of Nanjing Medical University2007，21，3： | 4 |
| 13 | Optical properties and chemical composition of PM_(2.5) in Shanghai in the spring of 2012显示文摘The semi-diurnal mean aerosol mass concentration, chemical composition, and optical properties of PM2.5were investigated in Shanghai during the spring of 2012. Slight pollution was observed during the study period. The average PM2.5 concentration was 64.11 土 22.83(xg/m3. The mean coefficients of extinction,scattering, and absorption at 532 nm were 125.9 士 78.5,91.1 士 56.3,and 34.9 士 23.6 Mm-1, respectively. A relatively low mean single scattering albedo at 532 nm(0.73 士 0.04) and low level of elemental carbon(EC,2.67 士 1.96 |xg/m3) suggested that the light absorption was enhanced due to the internal mixing of the EC.Sulfate contributed the most to aerosol light scattering in Shanghai. The chemical composition of PM2.5was dominated by particulate organic matter, sulfate, nitrate, ammonium, and EC. Anthropogenic sources made a significant contribution to the emission and loading of the particulate pollutants. A relatively good correlation between the aerosol chemical composition and the cloud condensation nuclei(CCN) activation indicated that aerosol chemistry is an important factor that influences the saturated hygroscopicity and growth of the aerosol. | Guanghan Huang Tiantao Cheng Renjian Zhang Jun Tao Chunpeng Leng Yunwei Zhang Shuping Zha Deqin Zhang Xiang Li Chunyang Xu | 2014 | Particuology2014，12，2： | 4 |
| 14 | Ln3+(Ln=Eu,Dy)-doped Sr2CeO4 fine phosphor particles:Wet chemical preparation,energy transfer and tunable luminescence显示文摘The Sr2 CeO4:Ln3+(Ln=Eu,Dy)fine phosphor particles were prepared by a facile wet chemical approach,in which the consecutive hydrothermal-combustion reaction was performed.The doping of Ln3+into Sr2 CeO4 has little influence on the structure of host,and the as-prepared samples display wellcrystallized spherical or elliptical shape with an average particle size at about 100-200 nm.For Eu3+ions-doped Sr2 CeO4,with the increase of Eu3+-doping concentration,the blue light emission band with the maximum at 468 nm originating from a Ce4+→O2-charge transfer of the host decreases obviously and the characteristic red light emission of Eu3+(5 D0→7 F2 transition at 618 nm)is enhanced gradually.Simultaneously,the fluorescent lifetime of the broadband emission of Sr2 CeO4 decreases with the doping of Eu3+,indicating an efficient energy transfer from the host to the doping Eu3+ions.The ene rgy transfer efficiency from the host to Eu3+was investigated in detail,and the emitting color of Sr2 CeO4:Eu3+can be easily tuned from blue to red by varying the doping concentration of Eu3+ions.Moreover,the luminescence of Dy3+-doped Sr2 CeO4 was also studied.Similar energy transfer pheno menon can be observed,and the incorporation of Dy3+into Sr2 CeO4 host leads to the characteristic emission of 4 F9/2→6 H15/2(488 nm,blue light)and 4 F9/2→6 H13/2(574 nm,yellow light)of Dy3+.The Sr2 CeO4:Ln3+fine particles with tunable luminescence are quite beneficial for its potential applications in the optoelectronic fields. | Na Gao Yanfei Yang Shikao Shi Jiye Wang Shuping Wang Jibiao Li Lianshe Fu | 2020 | Journal of Rare Earths2020，38，12： | 4 |
| 15 | Type-Ⅱ Core/Shell Nanowire Heterostructures and Their Photovoltaic Applications显示文摘Nanowire-based photovoltaic devices have the advantages over planar devices in light absorption and charge transport and collection.Recently,a new strategy relying on type-Ⅱ band alignment has been proposed to facilitate efficient charge separation in core/shell nanowire solar cells.This paper reviews the type-Ⅱ heterojunction solar cells based on core/shell nanowire arrays,and specifically focuses on the progress of theoretical design and fabrication of type-Ⅱ Zn O/Zn Se core/shell nanowire-based solar cells.A strong photoresponse associated with the type-Ⅱ interfacial transition exhibits a threshold of 1.6 e V,which demonstrates the feasibility and great potential for exploring all-inorganic versions of type-Ⅱ heterojunction solar cells using wide bandgap semiconductors.Future prospects in this area are also outlooked. | Yiyan Cao Zhiming Wu Jianchao Ni Waseem.A.Bhutto Jing Li Shuping Li Kai Huang Junyong Kang | 2012 | Nano-Micro Letters2012，4，3： | 3 |

| 17 | Dual alloying improves the corrosion resistance of biodegradable Mg alloys prepared by selective laser melting显示文摘Mg alloys have been regarded as revolutionary metallic biomaterials for biodegradable bone implants,but their applications are mainly blocked by the too rapid degradation in physiological environment.This study explores the dual alloying effects of Mn and/or Sn on the performance of Mg alloys prepared by selective laser melting.The observed microstructure indicated remarkable refinement of both the grains and intermetallic phases in the Mn-and/or Sn-containing alloys during the rapid solidification process.Moreover,approximately a half decrease in corrosion rate was observed for AZ61-0.4Mn-0.8Sn alloy with respect to AZ61 alloy.The improved corrosion behavior was primarily due to the enhanced protective effects of surface layers,in which Mn-and/or Sn-rich phases acted as a helpful barrier against medium penetration and thereby alleviated the current exchange with the matrix.In addition,the solute Mn and/or Sn positively shifted the corrosion potential,which also brought about a better corrosion resistance.Furthermore,the strength and hardness of the alloys were also effectively improved and comparable to those of cortical bone.This could be ascribed to the dissolved Mn and/or Sn atoms and the finely dispersed intermetallic phases,which might cause lattice distortion and precipitation hardening.Besides,the Mn-and/or Sn-containing alloys showed good cytocompatibility as indicated by the normal morphology and increased viability of MG-63 cells.These findings suggest that the developed AZ61-Mn-Sn alloy is a promising candidate for biodegradable bone implants. | Chengde Gao Sheng Li Long Liu Shizhen Bin Youwen Yang Shuping Peng Cijun Shuai | 2021 | Journal of Magnesium and Alloys2021，9，1： | 3 |

| 19 | Clear mortality gap caused by graft macrosteatosis in Chinese patients after cadaveric liver transplantation显示文摘Background:Liver transplantation(LT)is one of the most effective surgical treatment for patients with end-stage liver disease.Steatosis is a contributor for inferior graft quality.But its impact and safety on transplantation was less assessed in Chinese patients.Methods:Graft steatosis and related information involved in recipients,donors and surgical procedures were retrospectively collected from 239 patients.Results:Donor macrosteatosis(MaS)caused about 2.14 and 2.80 folds of increment on patient and graft mortality.Dose-response analysis revealed prominent risk of grafts on overall patient/organ mortality when MaS content exceeded 10%(P<0.05).Noteworthy,deaths were only observed in MaS group when concurrent with extremely higher post-transplant alanine aminotransferase(ALT,64%).However,microsteatosis(MiS)grafts didn’t affect outcomes after LT.In a cohort of Chinese patients,MaS had comprehensive effects on post-transplant outcomes with relatively lower safety threshold at 10%.Mortality gap caused by MaS grafts was observed in patients with severer ischemia reperfusion injury.Conclusions:Our study revealled the graft MaS affected the post-transplant outcomes in lower risk cutoff in Chinese patients.Further study is worthy to validate these results and investigate inner mechanism under the phenomenon. | Zhengtao Liu Wenchao Wang Li Zhuang Jingfeng Liu Shuping Que Dan Zhu Linfang Dong Jian Yu Lin Zhou Shusen Zheng | 2020 | Hepatobiliary Surgery and Nutrition2020，9，6： | 2 |
