| 1 | Constructions: A new theoretical approach to language显示文摘A new theoretical approach to language has emerged in the past 10-15 years that allows linguistic observations about form-meaning pairings constructions — to be stated directly. Constructionist approaches aim to account for the full range of facts about language, without assuming that a particular subset of the data is part of a privileged 揷ore? Researchers argue that unusual constructions shed light on more general issues, and serve to illuminate what is required for a complete account of language. | Adele E.

| 3 | Ten-year survival of hepatocellular carcinoma patients undergoing radiofrequency ablation as a first-line treatment显示文摘AIM: To investigate the long-term survival and prognostic factors in hepatocellular carcinoma(HCC) patients undergoing radiofrequency ablation(RFA) as a first-line treatment.METHODS: From 2000 to 2013, 316 consecutivepatients with 404 HCC(1.0-5.0 cm; mean: 3.2 ± 1.1 cm) underwent ultrasonography-guided percutaneous RFA as a first-line treatment. There were 250 males and 66 females with an average age of 60.1 ± 10.8 years(24-87 years). Patients were followed for 1 year to > 10 years after RFA(234, 181, 136, and 71 for 3, 5, 7, and 10 years, respectively). Overall local response rates and long-term survival rates were assessed. Survival results were generated using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression model. RESULTS: In total, 548 RFA sessions were performed and major complications occurred in 10 sessions(1.8%). Local tumor progression and/or new tumor development were observed in 43.3%(132/305) of the patients during the follow-up period. Overall 5-and 10-year survival rates were 49.7% and 28.4%, respectively. Based on multivariate analysis, three factors were identified as independent prognostic factors for overall survival: Child-Pugh classification(HR = 4.054, P < 0.001), portal vein hypertension(HR = 2.743, P = 0.002), and tumor number(HR = 2.693, P = 0.003). The local progression-free 5- and 10-year survival rates were 42.7% and 19.5%. In addition to the Child-Pugh classification and the number of tumors, the number of RFA sessions(HR = 1.550, P = 0.002) was associated with local progression-free survival.CONCLUSION: RFA can achieve acceptable outcomes for HCC patients as a first-line treatment, especially for patients with Child-Pugh class A, patients with a single tumor and patients without portal vein hypertension. | Wei Yang Kun Yan S Nahum Goldberg Muneeb Ahmed Jung-Chieh Lee Wei Wu Zhong-Yi Zhang Song Wang Min-Hua Chen | 2016 | World Journal of Gastroenterology2016，22，10： | 20 |
| 4 | Label-free detection of single nanoparticles and biological molecules using microtoroid optical resonators显示文摘Single-molecule detection is one of the fundamental challenges of modern biology.Such experiments often use labels that can be expensive,difficult to produce,and for small analytes,might perturb the molecular events being studied.Analyte size plays an important role in determining detectability.Here we use laser-frequency locking in the context of sensing to improve the signal-to-noise ratio of microtoroid optical resonators to the extent that single nanoparticles 2.5 nm in radius,and 15.5 kDa molecules are detected in aqueous solution,thereby bringing these detectors to the size limits needed for detecting the key macromolecules of the cell.Our results,covering several orders of magnitude of particle radius(100 nm to 2 nm),agree with the‘reactive’model prediction for the frequency shift of the resonator upon particle binding.This confirms that the main contribution of the frequency shift for the resonator upon particle binding is an increase in the effective path length due to part of the evanescent field coupling into the adsorbed particle.We anticipate that our results will enable many applications,including more sensitive medical diagnostics and fundamental studies of single receptor–ligand and protein–protein interactions in real time. | Judith Su Alexander FG Goldberg Brian M Stoltz | 2016 | Light(Science & Applications)2016，5，1： | 20 |

| 6 | Passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts and assessment of clinical outcomes显示文摘AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts(TIPS) and compare outcomes with maximally dilated TIPS.METHODS Polytetrafluoroethylene covered TIPS(Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm(m TIPS), while 43 patients who were at increased risk for hepatic encephalopathy(HE), based on clinical evaluation or low pre-TIPS portosystemic gradient(PSG), had 10 mm TIPS sub-maximally dilated to 8 mm(sm TIPS). Group characteristics(age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success(ascites or varices), primary patency,primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with sm TIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging(< 6 mo and > 6 mo). Change in diameter and crosssectional area were measured with 3D imaging software to evaluate for passive expansion.RESULTS Patient characteristics were similar between the sm TIPS and m TIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the sm TIPS group(19.4 mm Hg ± 6.8 vs 22.4 mm Hg ± 7.1, P = 0.01). Primary patency and primary assisted patency between sm TIPS and m TIPS was not significantly different(P = 0.64 and 0.55, respectively). Four of the 55 patients(7%) with sm TIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients(3%) with m TIPS(P = 0.12). For the 14 patients with follow-up computed tomography(CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo(8.45 mm, 5.58%, 56.04 mm^2, and 11.48%, respectively, P = 0.01).CONCLUSION Passive expansion of sm TIPS does occur but clinical outcomes of sm TIPS and m TIPS were similar. Sub-maximal dilation can prevent complications related to overshunting in select patients. | Michael C Hsu Charles N Weber S William Stavropoulos Timothy W Clark Scott O Trerotola Richard D Shlansky Goldberg Michael C Soulen Gregory J Nadolski | 2017 | World Journal of Hepatology2017，9，12： | 11 |

| 9 | National trends in resection of the distal pancreas显示文摘AIM:To investigate national trends in distal pancreatectomy(DP) through query of three national patient care databases.METHODS:From the Nationwide Inpatient Sample(NIS,2003-2009),the National Surgical Quality Improvement Project(NSQIP,2005-2010),and the Surveillance Epidemiology and End Results(SEER,2003-2009) databases using appropriate diagnostic and procedural codes we identified all patients with a diagnosis of a benign or malignant lesion of the body and/or tail of the pancreas that had undergone a partial or distal pancreatectomy.Utilization of laparoscopy was defined in NIS by the International Classification of Diseases,Ninth Revision correspondent procedure code;and in NSQIP by the exploratory laparoscopy or unlisted procedure current procedural terminology codes.In SEER,patients were identified by the International Classification of Diseases for Oncology,Third Edition diagnosis codes and the SEER Program Code Manual,third edition procedure codes.We analyzed the databases with respect to trends of inpatient outcome metrics,oncologic outcomes,and hospital volumes in patients with lesions of the neck and body of the pancreas that underwent operative resection.RESULTS:NIS,NSQIP and SEER identified 4242,2681 and 11 082 DP resections,respectively.Overall,laparoscopy was utilized in 15%(NIS) and 27%(NSQIP).No significant increase was seen over the course of the study.Resection was performed for malignancy in 59%(NIS) and 66%(NSQIP).Neither patient Body mass index nor comorbidities were associated with operative approach(P = 0.95 and P = 0.96,respectively).Mortality(3% vs 2%,P = 0.05) and reoperation(4% vs 4%,P = 1.0) was not different between laparoscopy and open groups.Overall complications(10% vs 15%,P < 0.001),hospital costs [44 741 dollars,interquartile range(IQR) 28 347-74 114 dollars vs 49 792 dollars,IQR 13 299-73 463,P = 0.02] and hospital length of stay(7 d,IQR 4-11 d vs 7 d,IQR 6-10,P < 0.001) were less when laparoscopy was utilized.One and two year survival after resection for malignancy were unchanged over the course of the study(ductal adenocarinoma 1-year 63.6% and 2-year 35.1%,P = 0.53;intraductal papillary mucinous neoplasm and nueroendocrine 1-year 90% and 2-year 84%,P = 0.25).The majority of resections were performed in teaching hospitals(77% NIS and 85% NSQIP),but minimally invasive surgery(MIS) was not more likely to be used in teaching hospitals(15% vs 14%,P = 0.26).Hospitals in the top decile for volume were more likely to be teaching hospitals than lower volume deciles(88% vs 43%,P < 0.001),but were no more likely to utilize MIS at resection.Complication rate in teaching and the top decile hospitals was not significantly decreased when compared to non-teaching(15% vs 14%,P = 0.72) and lower volume hospitals(14% vs 15%,P = 0.99).No difference was seen in the median number of lymph nodes and lymph node ratio in N1 disease when compared by year(P = 0.17 and P = 0.96,respectively).CONCLUSION:There appears to be an overall underutilization of laparoscopy for DP.Centralization does not appear to be occurring.Survival and lymph node harvest have not changed. | Armando Rosales-Velderrain Steven P Bowers Ross F Goldberg Tatyan M Clarke Mauricia A Buchanan John A Stauffer Horacio J Asbun | 2012 | World Journal of Gastroenterology2012，18，32： | 8 |
| 10 | Assessing keloid recurrence following surgical excision and radiation显示文摘Keloids are a fibroproliferative disorder that can result from a cutaneous injury to the reticular dermis.Recurrence rates as high as 100%have been reported following surgical excision alone.Consequently,a variety of post-surgical techniques have been employed to prevent keloid recurrence,including the use of radiation.Although numerous studies have shown post-excisional X-rays,electron beam,lasers and brachytherapy can reduce the rate of keloid recurrence,numerous inconsistencies,including a wide range of definitions for keloid recurrence,make it difficult to compare study outcomes.The review aims to examine the various means for defining keloid recurrence in clinical trials involving the use of radiation therapy.Searches of the Cochrane Library and PubMed were performed to identify the available information for post-surgical keloid recurrence following radiation therapy.Each identified study was reviewed for patient followup and criteria used to define keloid recurrence.The search results included clinical studies with external beam radiation,brachytherapy and superficial radiation therapy.Many studies did not include a definition of keloid recurrence,or defined recurrence only as the return of scar tissue.Other studies defined keloid recurrence based on patient self-assessment questionnaires,symptoms and scar elevation and changes in Kyoto Scar Scale,Japan Scar Workshop Scale and Vancouver Scar Scale scores.The results of this review indicate keloidectomy followed by radiation therapy provide satisfactory recurrence rates;however,clinical studies evaluating these treatments do not describe treatment outcomes or use different definitions of keloid recurrence.Consequently,recurrence rates vary widely,making comparisons across studies difficult.Keloid recurrence should be clearly defined using both objective and subjective measures. | Michael H.Gold Mark S.Nestor Brian Berman David Goldberg | 2020 | Burns & Trauma2020，8，1： | 8 |
| 11 | Ozone Profile Retrieval from Satellite Observation Using High Spectral Resolution Infrared Sounding Instrument显示文摘This paper presents a preliminary result on the retrieval of atmospheric ozone profiles using an im- proved regression technique and utilizing the data from the Atmospheric InfraRed Sounder (AIRS), a hyper-spectral Instrument expected to be flown on the EOS-AQUA platform in 20D2. Simulated AIRS spectra were used to study the sensitivity of AIRS radiance on the tropospheric and stratospheric ozone changes, and to study the impact of various channel combinations on the ozone profile retrieval. Sensitivity study results indicate that the AIRS high resolution spectral channels between the wavenumber 650- 800 cm-1 provide very useful information to accurately retrieve tropospheric and stratospheric ozone pro- files Eigenvector decomposition of AIRS spectra indicate that no more than 100 eigenvectors are needed to retrieve very accurate ozone profiles. The accuracy of the retrieved atmospheric ozone profile from the pres- ent technique and utilizing the AIRS data was compared with the accuracy obtained from current Advanced TIROS Operational Vertical Sounder (ATOVS) data aboard National Oceanic and Atmospheric Admini- stration (NOAA) satellites As expected, a comparison of retrieval results confirms that the ozone profile re- trieved with the AIRS data is superior to that of | Yanni Qu, Mitchell D.

| 17 | Electrical stimulation and denervated muscles after spinal cord injury显示文摘Spinal cord injury(SCI)population with injury below T10 or injury to the cauda equina region is characterized by denervated muscles,extensive muscle atrophy,infiltration of intramuscular fat and formation of fibrous tissue.These morphological changes may put individuals with SCI at higher risk for developing other diseases such as various cardiovascular diseases,diabetes,obesity and osteoporosis.Currently,there is no available rehabilitation intervention to rescue the muscles or restore muscle size in SCI individuals with lower motor neuron denervation.We,hereby,performed a review of the available evidence that supports the use of electrical stimulation in restoration of denervated muscle following SCI.Long pulse width stimulation(LPWS)technique is an upcoming method of stimulating denervated muscles.Our primary objective is to explore the best stimulation paradigms(stimulation parameters,stimulation technique and stimulation wave)to achieve restoration of the denervated muscle.Stimulation parameters,such as the pulse duration,need to be 100–1000 times longer than in innervated muscles to achieve desirable excitability and contraction.The use of electrical stimulation in animal and human models induces muscle hypertrophy.Findings in animal models indicate that electrical stimulation,with a combination of exercise and pharmacological interventions,have proven to be effective in improving various aspects like relative muscle weight,muscle cross sectional area,number of myelinated regenerated fibers,and restoring some level of muscle function.Human studies have shown similar outcomes,identifying the use of LPWS as an effective strategy in increasing muscle cross sectional area,the size of muscle fibers,and improving muscle function.Therefore,displaying promise is an effective future stimulation intervention.In summary,LPWS is a novel stimulation technique for denervated muscles in humans with SCI.Successful studies on LPWS of denervated muscles will help in translating this stimulation technique to the clinical level as a rehabilitation intervention after SCI. | Subhalakshmi Chandrasekaran John Davis Ines Bersch Gary Goldberg Ashraf S.Gorgey | 2020 | Neural Regeneration Research2020，15，8： | 3 |

| 19 | Organic Carbon Isotope Geochemistry of the Neoproterozoic Doushantuo Formation,South China显示文摘The Neoproterozoic Doushantuo Formation on the Yangtze Platform,South China,documents a sedimentary succession with different sedimentary facies from carbonate platform to slope and to deep sea basin,and hosts one of the world-class phosphorite deposits.In these strata,exquisitely preserved fossils have been discovered:the Weng’an biota.This study presents carbon isotope geochemistry which is associated paired carbonate and organic matter from the Weng’an section of a carbonate platform(shelf of the Yangtze Platform,Guizhou Province)from the Songtao section and Nanming section of a transition belt(slope of the Yangtze Platform,Guizhou Province)and from the Yanwutan section(basin area of the Yangtze Platform,Hunan Province).Environmental variations and bio-events on the Yangtze Platform during the Late Neoproterozoic and their causal relationship are discussed.Negative carbon isotope values for carbonate and organic carbon(mean δ13Corg = ?35.0‰)from the uppermost Nantuo Formation are followed by an overall increase in δ13C up-section.Carbon isotope values vary between ?9.9‰ and 3.6‰ for carbonate and between ?35.6‰ and ?21.5‰ for organic carbon,respectively.Heavier δ13Ccarb values suggest an increase in organic carbon burial,possibly related to increasing productivity(such as the Weng’an biota).The δ13C values of the sediments from the Doushantuo Formation decreased from the platform via the slope to basin,reflecting a reduced environment with minor dissolved inorganic carbon possibly due to a lower primary productivity.It is deduced that the classical upwelling process,the stratification structure and the hydrothermal eruption are principally important mechanisms to interpret the carbon isotopic compositions of the sediments from the Doushantuo Formation. | GUO Qingjun LIU Congqiang Harald STRAUSS Tatiana GOLDBERG ZHU Maoyan PI Daohui WANG Jian | 2006 | Acta Geologica Sinica(English Edition)2006，80，5： | 3 |
