| 1 | Liver histology in ICU patients dying from sepsis:A clinico-pathological study显示文摘AIM:To determine end-stage pathologic changes in the liver of septic patients dying in the intensive care unit. METHODS: Needle liver biopsies obtained immediately after death from 15 consecutive patients with sepsis and no underlying liver disease were subjected to routine histological examination. Liver function tests and clinical monitoring measurements were also recorded. RESULTS: Liver biochemistries were increased in the majority of patients before death. Histology of liver bi- opsy specimens showed portal inflammation in 73.3%, centrilobular necrosis in 80%, lobular inflammation in 66.7%, hepatocellular apoptosis in 66.6% and cholan- gitis/cholangiolitis in 20% of patients. Mixed hepatitic/ cholestatic type of liver injury was observed in 6/15 (40%) patients and hepatitc in 9/15 (60%). Steatosis was ob- served in 11/15 (73.3%) patients affecting 5%-80% of liver parenchyma. Among the histological features, the presence of portal inflammation in liver biopsy was as- sociated with increased hospitalization in the ICU prior death (P = 0.026). CONCLUSION: Features of hepatitis and steatosis arethe main histological findings in the liver in the majority of patients dying from sepsis. | John Koskinas Ilias P Gomatos Dina G Tiniakos Nikolaos Memos Maria Boutsikou Aspasia Garatzioti Athanasios Archimandritis Alexander Betrosian | 2008 | World Journal of Gastroenterology2008，14，9： | 8 |
| 2 | Machine-learned multi-system surrogate models for materials prediction显示文摘Surrogate machine-learning models are transforming computational materials science by predicting properties of materials with the accuracy of ab initio methods at a fraction of the computational cost.We demonstrate surrogate models that simultaneously interpolate energies of different materials on a dataset of 10 binary alloys(AgCu,AlFe,AlMg,AlNi,AlTi,CoNi,CuFe,CuNi,FeV,and NbNi)with 10 different species and all possible fcc,bcc,and hcp structures up to eight atoms in the unit cell,15,950 structures in total.We find that the deviation of prediction errors when increasing the number of simultaneously modeled alloys is<1 meV/atom.Several state-of-the-art materials representations and learning algorithms were found to qualitatively agree on the prediction errors of formation enthalpy with relative errors of<2.5% for all systems. | Chandramouli Nyshadham Matthias Rupp Brayden Bekker Alexander V.Shapeev Tim Mueller Conrad W.Rosenbrock Gábor Csányi David W.Wingate Gus L.W.Hart | 2019 | npj Computational Materials2019，，1： | 8 |
| 3 | Current concepts on spinal arthrodesis in degenerative disorders of the lumbar spine显示文摘Back pain is a common chronic disorder that represents a large burden for the health care system. There is a broad spectrum of available treatment options for patients suffering from chronic lower back pain in the setting of degenerative disorders of the lumbar spine, including both conservative and operative approaches. Lumbar arthrodesis techniques can be divided into subcategories based on the part of the vertebral column that is addressed(anterior vs posterior). Furthermore, one has to differentiate between approaches aiming at a solid fusion in contrast to motion-sparing techniques with the proposed advantage of a reduced risk of developing adjacent disc disease. However, the field of application and long-term outcomes of these novel motion-preserving surgical techniques, including facet arthroplasty, nucleus replacement, and lumbar disc arthroplasty, need to be more precisely evaluated in long-term prospective studies. Innovative surgical treatment strategies involving minimally invasive techniques, such as lateral lumbar interbody fusion or transforaminal lumbar interbody fusion, as well as percutaneous implantation of transpedicular or trans-facet screws, have been established with the reported advantages of reduced tissue invasiveness, decreased collateral damage, reduced blood loss, and decreased risk of infection. The aim of this study was to review well-established procedures for lumbar spinal fusion with the main focus on current concepts on spinal arthrodesis and motion-sparing techniques in degenerative disorders of the lumbar spine. | Marios G Lykissas Alexander Aichmair | 2013 | World Journal of Clinical Cases2013，1，1： | 7 |
| 4 | 纤维母细胞生长因子对复合皮肤移植成活和收缩的影响显示文摘我们曾报道应用同基因表层皮片(IE)和同种异基因真皮(AD)组成复合皮肤移植物(CSG)可一次完成全层皮肤缺损的永久性修复。但由于IE不能及时获得足够血运,IE常有部分坏死,CSG后期收缩仍较明显。在本研究中我们进一步用纤维母细胞生长因子(FGF)预先处理AD获得较好效果。经观察17周表明,FGF组皮片坏死率和坏死面积较对照组明显下降(P<0.05);FGF组CSG收缩较对照组明显减轻(P<0.001);皮片坏死面积与皮片最终面积呈负相关(r=-0.450,P<0.05)。实验预示,完全成活的CSG后期收缩较移植同等厚度的IE为轻。观察2年,AD未被排斥。 | 方承辉 Robb E C 于光曙 Alexander J W Warden G D | 1993 | 中华整形烧伤外科杂志1993，9，1： | 6 |
| 5 | Primary squamous cell carcinoma of the rectum: An update and implications for treatment显示文摘AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma(SCC).METHODS: A systematic review was conducted according to the preferred reporting items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in concert.RESULTS: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal SCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal SCC's are in fact an extension of an anal SCC, and cytokeratin markers are a useful adjunct in this distinction. Staging is most accurately reflected by the tumour-nodemetastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external siteof primary SCC with metastasis to the rectum. While the optimal treatment remains as yet undefined, recent studies have demonstrated a global shift away from surgery towards definitive chemoradiotherapy as primary treatment. Pooled overall survival was calculated to be 86% in patients managed with chemoradiation compared with 48% for those treated traditionally with surgery. Furthermore, local recurrence and metastatic rates were 25% vs 10% and 30% vs 13% for the chemoradiation vs conventional treatment cohorts.CONCLUSION: The changing paradigm in the treatment of rectal SCC holds great promise for improved outcomes in this rare disease. | Glen R Guerra Cherng H Kong Satish K Warrier Andrew C Lynch Alexander G Heriot Samuel Y Ngan | 2016 | World Journal of Gastrointestinal Surgery2016，8，3： | 5 |
| 6 | Curcumin induces differentiation of embryonic stem cells through possible modulation of nitric oxide-cyclic GMP pathway显示文摘Curcumin,an active ingredient of dietary spice used in curry,has been shown to exhibit anti-oxidant,anti-inflammatory and anti-proliferative properties.Using EB directed differentiation protocol of H-9 human em-bryonic stem(ES)cells;we evaluated the effect of cur-cumin(0-20μmol/L)in enhancing such differentiation.Our results using real time PCR,western blotting and immunostaining demonstrated that curcumin signifi-cantly increased the gene expression and protein levels of cardiac specific transcription factor NKx2.5,cardiac troponin I,myosin heavy chain,and endothelial nitric oxide synthase during ES cell differentiation.Further-more,an NO donor enhanced the curcumin-mediated induction of NKx2.5 and other cardiac specific proteins.Incubation of cells with curcumin led to a dose depend-ent increase in intracellular nitrite to the same extent as giving an authentic NO donor.Functional assay for second messenger(s)cyclic AMP(cAMP)and cyclic GMP(cGMP)revealed that continuous presence of cur-cumin in differentiated cells induced a decrease in the baseline levels of cAMP but it significantly elevated baseline contents of cGMP.Curcumin addition to a cell free assay significantly suppressed cAMP and cGMP degradation in the extracts while long term treatment of intact cells with curcumin increased the rates of cAMP and cGMP degradation suggesting that this might be due to direct suppression of some cyclic nucleo-tide-degrading enzyme(phosphodiesterase)by curcu-min.These studies demonstrate that polyphenol curcu-min may be involved in differentiation of ES cells partly due to manipulation of nitric oxide signaling. | Kalpana Mujoo Lubov ENikonoff Vladislav G Sharin Nathan SBryan Alexander YKots Ferid Murad | 2012 | Protein & Cell2012，3，7： | 5 |
| 7 | Machine-learned interatomic potentials for alloys and alloy phase diagrams显示文摘We introduce machine-learned potentials for Ag-Pd to describe the energy of alloy configurations over a wide range of compositions.We compare two different approaches.Moment tensor potentials(MTPs)are polynomial-like functions of interatomic distances and angles.The Gaussian approximation potential(GAP)framework uses kernel regression,and we use the smooth overlap of atomic position(SOAP)representation of atomic neighborhoods that consist of a complete set of rotational and permutational invariants provided by the power spectrum of the spherical Fourier transform of the neighbor density.Both types of potentials give excellent accuracy for a wide range of compositions,competitive with the accuracy of cluster expansion,a benchmark for this system.While both models are able to describe small deformations away from the lattice positions,SOAP-GAP excels at transferability as shown by sensible transformation paths between configurations,and MTP allows,due to its lower computational cost,the calculation of compositional phase diagrams.Given the fact that both methods perform nearly as well as cluster expansion but yield off-lattice models,we expect them to open new avenues in computational materials modeling for alloys. | Conrad W.Rosenbrock Konstantin Gubaev Alexander VShapeev Livia B.Pártay Noam Bernstein Gábor Csányi Gus L.W.Hart | 2021 | npj Computational Materials2021，，1： | 5 |
| 8 | Engineering osteoarthritic cartilage model through differentiating senescent human mesenchymal stem cells for testing disease-modifying drugs显示文摘Significant cellular senescence has been observed in cartilage harvested from patients with osteoarthritis(OA).In this study,we aim to develop a senescence-relevant OA-like cartilage model for developing disease-modifying OA drugs(DMOADs).Spe-cifically,human bone marrow-derived mesenchymal stromal cells(MSCs)were expanded in vitro up to passage 10(P10-MSCs).Following their senescent phenotype formation,P10-MSCs were subjected to pellet culture in chondrogenic medium.Results from qRT-PCR,histology,and immunostaining indicated that cartilage generated from P10-MSCs displayed both senescent and OA-like phenotypes without using other OA-inducing agents,when compared to that from normal passage 4(P4)-MSCs.Interestingly,the same gene expression differences observed between P4-MSCs and P10-MSC-derived cartilage tissues were also observed between the preserved and damaged OA cartilage regions taken from human samples,as demonstrated by RNA sequencing data and other analysis methods.Lastly,the utility of this senescence-initiated OA-like cartilage model in drug development was assessed by testing several potential DMOADs and senolytics.The results suggest that pre-existing cellular senescence can induce the generation of OA-like changes in cartilage.The P4-and P10-MSCs derived cartilage models also represent a novel platform for predicting the efficacy and toxicity of potential DMOADs on both preserved and damaged cartilage in humans. | Ning Wang Yuchen He Silvia Liu Meagan J.Makarcyzk Guanghua Lei Alexander Chang Peter G Alexander Tingjun Hao Anne-Marie Padget Nuria de Pedro Tsapekos Menelaos Hang Lin | 2022 | Science China(Life Sciences)2022，65，2： | 5 |
| 9 | Antioxidant enriched enteral nutrition and oxidative stress after major gastrointestinal tract surgery显示文摘AIM: To investigate the effects of an enteral supple-ment containing antioxidants on circulating levels of antioxidants and indicators of oxidative stress after major gastrointestinal surgery.METHODS: Twenty-one patients undergoing major upper gastrointestinal tract surgery were randomised in a single centre, open label study on the effect of postoperative enteral nutrition supplementedwith antioxidants. The effect on circulating levels of antioxidants and indicators of oxidative stress, such as F2-isoprostane, was studied. RESULTS: The antioxidant enteral supplement showed no adverse effects and was well tolerated. After surgery a decrease in the circulating levels of antioxidant parameters was observed. Only selenium and glutamine levels were restored to pre-operative values one week after surgery. F2-isoprostane increased in the first three postoperative days only in the antioxidant supplemented group. Lipopolysaccharide binding protein (LBP) levels decreased faster in the antioxidant group after surgery.CONCLUSION: Despite lower antioxidant levels there was no increase in the circulating markers of oxidative stress on the first day after major abdominal surgery. The rise in F2-isoprostane in patients receiving the antioxidant supplement may be related to the conversion of antioxidants to oxidants which raises questions on antioxidant supplementation. Module AOX restored the postoperative decrease in selenium levels. The rapid decrease in LBP levels in the antioxidant group suggests a possible protective effect on gut wall integrity. Further studies are needed on the role of oxidative stress on outcome and the use of antioxidants in patients undergoing major abdominal surgery. | Mireille FM van Stijn Gerdien C Ligthart-Melis Petra G Boelens Peter G Scheffer Tom Teerlink Jos WR Twisk Alexander PJ Houdijk Paul AM van Leeuwen | 2008 | World Journal of Gastroenterology2008，14，45： | 4 |

| 18 | Nitrogen and Carbon Isotope Data of Olenekian to Anisian Deposits from Kamenushka/South Primorye, Far-Eastern Russia and Their Palaeoenvironmental Significance显示文摘The Kamenushka Formation, exposed in the northern part of South Primorye(Kamenushka-1 and Kamenushka-2 sections), is one of the few localities in the world with richly fossiliferous Lower–Upper Olenekian sedimentary successions. Lower to Middle Triassic ammonoid-, brachiopod-and conodont-bearing silty-clayey deposits of the Kamenushka-1 and Kamenushka-2 sections have been isotope-geochemically investigated in detail. As a result, these sections, together with the previously investigated Abrek Section, exposed in the southern part of South Primorye, provide almost complete 15 Norg-and 13 Corg-records for the Lower Triassic of this region. Nine Nisotope intervals and the five negative C-isotope excursions, reflecting, apparently, unstable climatic and hydrological conditions, have been distinguished in the Lower Triassic of South Primorye. On the basis of the new C-isotope data the Mesohedenstroemia bosphorensis Zone(upper part), Shimanskyites shimanskyi and Neocolumbites insignis zones of South Primorye are correlated now with the Lower Smithian part of the Yinkeng Formation, the Upper Smithian part of the Helongshan Formation and the Middle Spathian part of the Nanlinghu Formation in South China, respectively, as has been observed in the Abrek, Kamenushka-2, West Pingdingshan and Majiashan sections. | Yuri D Zakharov Micha Horacek Alexander M Popov Liana G Bondarenko | 2018 | Journal of Earth Science2018，29，4： | 2 |
| 19 | Donor-specific cell-free DNA as a biomarker in liver transplantation:A review显示文摘Due to advances in modern medicine,liver transplantation has revolutionised the prognosis of many previously incurable liver diseases.This progress has largely been due to advances in immunosuppressant therapy.However,despite the judicious use of immunosuppression,many liver transplant recipients still experience complications such as rejection,which necessitates diagnosis via invasive liver biopsy.There is a clear need for novel,minimally-invasive tests to optimise immunosuppression and improve patient outcomes.An emerging biomarker in this‘‘precision medicine’‘liver transplantation field is that of donorspecific cell free DNA.In this review,we detail the background and methods of detecting this biomarker,examine its utility in liver transplantation and discuss future research directions that may be most impactful. | Tess McClure Su Kah Goh Daniel Cox Vijayaragavan Muralidharan Alexander Dobrovic Adam G Testro | 2020 | World Journal of Transplantation2020，10，11： | 2 |
