| 1 | Contrast-enhanced ultrasound in the diagnosis of nodules in liver cirrhosis显示文摘Contrast-enhanced ultrasound(CEUS)using microbubble contrast agents are useful for the diagnosis of the nodules in liver cirrhosis.CEUS can be used as a problem-solving method for indeterminate nodules on computed tomography(CT)or magnetic resonance imaging(MRI)or as an initial diagnostic test for small newly detected liver nodules.CEUS has unique advantages over CT and MRI including no renal excretion of contrast,real-time imaging capability,and purely intravascular contrast.Hepatocellular carcinoma(HCC)is characterized by arterial-phase hypervascularity and later washout(negative enhancement).Benign nodules such as regenerative nodules or dysplastic nodules are usually isoechoic or slightly hypoechoic in the arterial phase and isoechoic in the late phase.However,there are occasional HCC lesions with atypical enhancement including hypovascular HCC and hypervascular HCC without washout.Cholangiocarcinomas are infrequently detected during HCC surveillance and mostly show rimlike or diffuse hypervascularity followed by rapid washout.Hemangiomas are often found at HCC surveillance and are easily diagnosed by CEUS.CEUS can be effectively used in the diagnostic work-up of small nodules detected at HCC surveillance.CEUS is also useful to differentiate malignant and benign venous thrombosis and to guide and monitor the local ablation therapy for HCC. | Tae Kyoung Kim Hyun-Jung | 2014 | World Journal of Gastroenterology2014，20，13： | 36 |
| 2 | Real time shear wave elastography in chronic liver diseases:Accuracy for predicting liver fibrosis,in comparison with serum markers显示文摘AIM:To evaluate the correlation between liver stiffness measurement(LSM)by real-time shear wave elastography(SWE)and liver fibrosis stage and the accuracy of LSM for predicting significant and advanced fibrosis,in comparison with serum markers.METHODS:We consecutively analyzed 70 patients with various chronic liver diseases.Liver fibrosis was staged from F0 to F4 according to the Batts and Ludwig scoring system.Significant and advanced fibrosis was defined as stage F≥2 and F≥3,respectively.The accuracy of prediction for fibrosis was analyzed using receiver operating characteristic curves.RESULTS:Seventy patients,15 were belonged to F0-F1 stage,20 F2,13 F3 and 22 F4.LSM was increased with progression of fibrosis stage(F0-F1:6.77±1.72,F2:9.98±3.99,F3:15.80±7.73,and F4:22.09±10.09,P<0.001).Diagnostic accuracies of LSM for prediction of F≥2 and F≥3 were 0.915(95%CI:0.824-0.968,P<0.001)and 0.913(95%CI:0.821-0.967,P<0.001),respectively.The cut-off values of LSM for prediction of F≥2 and F≥3 were 8.6kPa with 78.2%sensitivity and 93.3%specificity and10.46 kPa with 88.6%sensitivity and 80.0%specificity,respectively.However,there were no significant differences between LSM and serum hyaluronic acid and typeⅣcollagen in diagnostic accuracy.CONCLUSION:SWE showed a significant correlation with the severity of liver fibrosis and was useful and accurate to predict significant and advanced fibrosis,comparable with serum markers. | Jae Yoon Jeong Tae Yeob Kim Joo Hyun Sohn Yongsoo Kim Woo Kyoung Jeong Young-Ha Oh Kyo-Sang Yoo | 2014 | World Journal of Gastroenterology2014，20，38： | 19 |

| 5 | Invasive and non-invasive diagnosis of cirrhosis and portal hypertension显示文摘With advances in the management and treatment of advanced liver disease,including the use of antiviral therapy,a simple,one stage description for advanced fibrotic liver disease has become inadequate.Although refining the diagnosis of cirrhosis to reflect disease heterogeneity is essential,current diagnostic tests have not kept pace with the progression of this new paradigm.Liver biopsy and hepatic venous pressure gradient measurement are the gold standards for the estimation of hepatic fibrosis and portal hypertension(PHT),respectively,and they have diagnostic and prognostic value.However,they are invasive and,as such,cannot be used repeatedly in clinical practice.The ideal noninvasive test should be safe,easy to perform,inexpensive,reproducible as well as to give numerical and accurate results in real time.It should be predictive of long term outcomes related with fibrosis and PHT to allow prognostic stratification.Recently,many types of noninvasive alternative tests have been developed and are under investigation.In particular,imaging and ultrasound based tests,such as transient elastography,have shown promising results.Although most of these noninvasive tests effectively identify severe fibrosis and PHT,the methods available for diagnosing moderate disease status are still insufficient,and further investigation is essential to predict outcomes and individualize therapy in this field. | Moon Young Kim Woo Kyoung Jeong Soon Koo Baik | 2014 | World Journal of Gastroenterology2014，20，15： | 13 |
| 6 | Anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium-induced colitis model显示文摘AIM To evaluate the anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium(DSS)-induced colitis model.METHODS An acute colitis mouse model was induced by oral administration of 5% DSS in the drinking water for 7 d. In the treated group, rosuvastatin(0.3 mg/kg per day) was administered orally before and after DSS administration for 21 d. On day 21, mice were sacrificed and the colons were removed for macroscopic examination, histology, and Western blot analysis. In the in vitro study, IEC-6 cells were stimulated with50 ng/m L tumor necrosis factor(TNF)-α and then treated with or without rosuvastatin(2 μmol/L). The levels of reactive oxygen species(ROS), inflammatory mediators, and apoptotic markers were measured. RESULTS In DSS-induced colitis mice, rosuvastatin treatment significantly reduced the disease activity index and histological damage score compared to untreated mice(P < 0.05). Rosuvastatin also attenuated the DSSinduced increase of 8-hydroxy-2'-deoxyguanosine and NADPH oxidase-1 expression in colon tissue. Multiplex ELISA analysis revealed that rosuvastatin treatment reduced the DSS-induced increase of serum IL-2, IL-4, IL-5, IL-6, IL-12 and IL-17, and G-CSF levels. The increased levels of cleaved caspase-3, caspase-7, and poly(ADP-ribose) polymerase in the DSS group were attenuated by rosuvastatin treatment. In vitro, rosuvastatin significantly reduced the production of ROS, inflammatory mediators and apoptotic markers in TNF-α-treated IEC-6 cells(P < 0.05).CONCLUSION Rosuvastatin had the antioxidant, anti-inflammatory and anti-apoptotic effects in DSS-induced colitis model. Therefore, it might be a candidate anti-inflammatory drug in patients with inflammatory bowel disease. | Seung Kak Shin Jae Hee Cho Eui Joo Kim Eun-Kyung Kim Dong Kyun Park Kwang An Kwon Jun-Won Chung Kyoung Oh Kim Yoon Jae Kim | 2017 | World Journal of Gastroenterology2017，23，25： | 11 |
| 7 | The Effect of Toxic Sulfide Exposure on Oxygen Consumption and Oxidation Products in Urechis unicinctus(Echiura:Urechidae)显示文摘To investigate sulfide detoxification in Urechis unicinctus,oxygen consumption rate and sulfide detoxification productswere analyzed during sulfide exposure under controlled laboratory conditions.The results showed that oxygen consumption rateswere elevated significantly during 3 h sulfide exposure compared to the control(P<0.05).The concentration of sulfite in body walland hindgut of experimental worms increased significantly(P<0.05)when exposed to 50μmolL-1sulfide,reached a maximum at24 h and then decreased.Similar result was observed in worms exposed to 150μmolL-1sulfide except that sulfite concentrationreached a maximum at 12 h.Contents of thiosulfate in body wall and hindgut of U.unicinctus exposed to sulfide were also significantly higher than that of the control without sulfide exposure.In conclusion,during short-time sulfide exposure U.unicinctus mayraise oxygen consumption to detoxify toxic sulfide into sulfite and thiosulfate.Sulfide detoxification was restrained when the expo-sure time was prolonged or sulfide concentration was increased,which was indicated by decrease of sulfite,the intermediate productof sulfide detoxification. | WANG Sifeng ZHANG Zhifeng CUI He KANG Kyoung Ho MA Zhuojun | 2010 | Journal of Ocean University of China2010，9，2： | 10 |
| 8 | Endoscopic features suggesting gastric cancer in biopsy-proven gastric adenoma with high-grade neoplasia显示文摘AIM:To elucidate the endoscopic features that predict the cancer following endoscopic submucosal dissection(ESD)in patients with high-grade neoplasia(HGN).METHODS:We retrospectively analyzed the medical records of patients who underwent ESD of gastric neoplasms from January 2007 to September 2010.ESD was performed in 555 cases involving 550 patients.A total of 112 lesions from 110 consecutive patients were initially diagnosed as HGN without cancer by forceps biopsy,and later underwent ESD.We classified lesions into two groups according to histologic discrepancies between the biopsy and ESD diagnosis.Gastric adenoma in the final diagnosis by ESD specimens were defined as adenoma group.Lesions with coexisting cancer after ESD were defined as cancer group.RESULTS:The mean age was 65.3 years,and 81 patients were male.There was no significant difference in the age or gender distribution between the adenoma(n=52)and cancer(n=60)groups.Thirty-six of these lesions(32.1%)showed histologic concordance between the forceps biopsy and ESD specimens,16(14.3%)showed a downgraded histology(low-grade neoplasia),and 60(53.6%)showed an upgraded histology(cancer).A red color change of the mucosal surface on endoscopy was found in 27/52(51.9%)of cases in the adenoma group and in 46/60(76.7%)of cases in the cancer group(P=0.006).Ulceration of the mucosal surface on endoscopy was found in 5(9.6%)of 52 lesions in the adenoma group and in 17(28.3%)of 60 lesions in the cancer group(P=0.013).In the multivariate analysis,a reddish surface color change and mucosal ulceration were significant predictive factors correlated with cancer after ESD of the HGN by forceps biopsy.CONCLUSION:HGN with a red color change or mucosal ulceration correlated with the presence of gastric cancer.These finding may help to guide the diagnosis and treatment. | Jung Ho Kim Yoon Jae Kim Jungsuk An Jong Joon Lee Jae Hee Cho Kyoung Oh Kim Jun-Won Chung Kwang An Kwon Dong Kyun Park Ju Hyun Kim | 2014 | World Journal of Gastroenterology2014，20，34： | 10 |
| 9 | Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy显示文摘Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically. | Youn Son Chung Yong Woo Chung Sun You Moon Su Mi Yoon Min-Jeong Kim Kyoung Oh Kim Cheol Hee Park Taeho Hahn Kyo-Sang Yoo Sang Hoon Park Jong Hyeok Kim Choong Kee Park | 2008 | World Journal of Gastroenterology2008，14，6： | 10 |
| 10 | Temperature Distribution and Thermal Stresses in Various Conditions of Moving Heating Source during Line Heating Process显示文摘Line heating method is widely used to manufacture curved surfaces in ship building. The main factors governing the quality of the manufactured products are the moving velocity of the heating source, heating strength, and heating ways. In this study, the temperature distributions of the heated plate were investigated with the condition that the line heating process was automatic. The temperature variations were also investigated with the changes of those three variables. The numerical results showed that the peak temperature decreased as the moving velocity of the heating source increased. It also revealed that the peak temperatures changed linearly with the changes of the heating source. | Yoon Hwan Choi Yeon Won Lee Kwang Choi Deog Hee Doh Kyoung Joon Kim | 2012 | Journal of Thermal Science2012，21，1： | 10 |
| 11 | Entransy and Exergy Analyses for Optimizations of Heat-Work Conversion with Carnot Cycle显示文摘The concept of entransy has been newly proposed in terms of the analogy between heat and electrical conduction and could be useful in analyzing and optimizing the heat-work conversion systems.This work presents comparative analyses of entransy and exergy for optimizations of heat-work conversion.The work production and heat transfer processes in Carnot cycle system are investigated with the formulations of exergy destruction,entransy loss,work entransy,entransy dissipation,and efficiencies for both cases of dumping and non-dumping of used source fluid.The effects of source and condensation temperatures on the system performance are systematically investigated for optimal condition of producing maximum work or work entransy. | Chul Ho Han Kyoung Hoon Kim | 2016 | Journal of Thermal Science2016，25，3： | 10 |
| 12 | Management of gastric subepithelial tumors:The role of endoscopy显示文摘With the wide use of esophagogastroduodenoscopy,the incidence of gastric subepithelial tumor(SET)diagnosis has increased.While the management of large orsymptomatic gastric SETs is obvious,treatment of small(≤3 cm)asymptomatic gastric SETs remains inconclusive.Moreover,the presence of gastrointestinal stromal tumors with malignant potential is of concern,and endoscopic treatment of gastric SETs remains a subject of debate.Recently,numerous studies have demonstrated the feasibility of endoscopic treatment of gastric SETs,and have proposed various endoscopic procedures including endoscopic submucosal dissection,endoscopic muscularis dissection,endoscopic enucleation,endoscopic submucosal tunnel dissection,endoscopic full-thickness resection,and a hybrid approach(the combination of endoscopy and laparoscopy).In this review article,we discuss current endoscopic treatments for gastric SETs as well as the advantages and limitations of this type of therapy.Finally,we predict the availability of newly developed endoscopic treatments for gastric SETs. | Su Young Kim Kyoung Oh Kim | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，11： | 10 |

| 14 | Clinical advantages of single port laparoscopic hepatectomy显示文摘AIM To evaluate the clinical advantages of single-port laparoscopic hepatectomy(SPLH) compare to multiport laparoscopic hepatectomy(MPLH).METHODS We retrospectively reviewed the medical records of 246 patients who underwent laparoscopic liver resection between January 2008 and December 2015 at our hospital. We divided the surgical technique into two groups; SPLH and MPLH. We performed laparoscopic liver resection for both benign and malignant disease. Major hepatectomy such as right and left hepatectomy was also done with sufficient disease-free margin. The operative time, the volume of blood loss, transfusion rate, and the conversion rate to MPLH or open surgery was evaluated. The post-operative parameters included the meal start date after operation, the number of postoperative days spent in the hospital, and surgical complications was also evaluated.RESULTS Of the 246 patients, 155 patients underwent SPLH and 91 patients underwent MPLH. Conversion rate was 22.6% in SPLH and 19.8% in MPLH(P = 0.358). We performed major hepatectomy, which was defined as resection of more than 2 sections, in 13.5% of patients in the SPLH group and in 13.3% of patients in the MPLH group(P = 0.962). Mean operative timewas 136.9 ± 89.2 min in the SPLH group and 231.2 ± 149.7 min in the MPLH group(P < 0.001). The amount of blood loss was 385.1 ± 409.3 m L in the SPLH group and 559.9 ± 624.9 m L in the MPLH group(P = 0.016). The safety resection margin did not show a significant difference(0.84 ± 0.84 cm in SPLH vs 1.04 ± 1.22 cm in MPLH, P = 0.704). Enteral feeding was started earlier in the SPLH group(1.06 ± 0.27 d after operation) than in the MPLH group(1.63 ± 1.27 d)(P < 0.001). The mean hospital stay after operation was non-significantly shorter in the SPLH group than in the MPLH group(7.82 ± 2.79 d vs 7.97 ± 3.69 d, P = 0.744). The complication rate was not significantly different(P = 0.397) and there was no major perioperative complication or mortality case in both groups. CONCLUSION Single-port laparoscopic liver surgery seems to be a feasible approach for various kinds of liver diseases. | Jae Hyun Han Young Kyoung You Ho Joong Choi Tae Ho Hong Dong Goo Kim | 2018 | World Journal of Gastroenterology2018，24，3： | 9 |
| 15 | Refractive errors in high myopic eyes after phacovitrectomy for macular hole显示文摘AIM: To examine the refractive prediction error in high myopic eyes after phacovitrectomy.METHODS: This retrospective comparative case series included 91 eyes(18 high myopic eyes and 73 non-high myopic eyes) of 91 patients who underwent successful phacovitrectomy(phacoemulsification, intraocular lens implantation, and pars plana vitrectomy). The high myopic eyes were defined as the eye with more than 26.0mm of axial length. The postoperative prediction error of mean error and mean absolute error were evaluated at4 mo postoperatively. Axial length and keratometry measurement were performed preoperatively and 4mo postoperatively using the IOL Master.RESULTS: The refractive outcome after phacovitrectomy showed significantly greater myopic shift in the high myopic eyes [-1.08 ±0.87 diopters(D)] than that in the non-high myopic eyes(-0.43 ±0.63 D, P =0.004). Axial length and keratometric value in the high myopic eyes were significantly increased(P =0.043, 0.037 respectively),whereas those in the non-high myopic group were not significantly increased(P =0.135, 0.347 respectively). The change of the axial length in the myopic eye(0.46±0.28 mm)was greater than that in the non- high myopic eye(0.11 ± 0.34 mm; P <0.001).CONCLUSION: High myopic eyes showed more myopic shift than non-high myopic eyes after phacovitrectomy.The cause of myopic shift in high myopic eyes seems tobe attributed to actual elongation of the axial length in high myopia. | Donghyun Jee Yi-Ryeung Park Kyoung In Jung Eunchul Kim Tae Yoon La | 2015 | International Journal of Ophthalmology(English edition)2015，8，2： | 9 |
| 16 | Evaluation of prognostic factors on recurrence after curative resections for hepatocellular carcinoma显示文摘AIM:To select appropriate patients before surgical resection for hepatocellular carcinoma(HCC),especially those with advanced tumors.METHODS:From January 2000 to December 2012,we retrospectively analyzed the medical records of 298 patients who had undergone surgical resections for HCC with curative intent at our hospital.We evaluated preoperative prognostic factors associated with histologic grade of tumor,recurrence and survival,especially the findings of pre-operative imaging studies such as positron emission tomography-computed tomography(PETCT)and magnetic resonance imaging(MRI).And then,we established a scoring system to predict recurrence and survival after surgery dividing the patients into two groups based on a tumor size of 5 cm.RESULTS:Of the 298 patients,129(43.3%)developed recurrence during the follow-up period.The 5 year disease free survival and overall survival were 47.0%and58.7%respectively.In multivariate analysis,a serum alpha-fetoprotein(AFP)level of>100 ng/m L and a standardized uptake value(SUV)of PET-CT of>3.5 were predictive factors for histologic grade of tumor,recurrence,and survival.Tumor size of>5 cm and a relative enhancement ratio(RER)calculated from preoperative MRI were also significantly associated with prognosis in univariate analysis.We established a scoring system to predict prognosis using AFP,SUV,and RER.In those with tumors of>5 cm,it showed predicted both recurrence(P=0.005)and survival(P=0.001).CONCLUSION:The AFP,tumor size,SUV and RER are useful for prognosis preoperatively.An accurate prediction of prognosis is possible using our scoring system in large size tumors. | Jae Hyun Han Dong Goo Kim Gun Hyung Na Eun Young Kim Soo Ho Lee Tae Ho Hong Young Kyoung You | 2014 | World Journal of Gastroenterology2014，20，45： | 8 |
| 17 | Comparison of postoperative optical quality according to the degree of decentering of V4c implantable collamer lens显示文摘AIM:To evaluate the clinical outcomes of V4 c implantable collamer lens(Hole ICL) implantation with regard to the optical quality assessed according to different degrees of decentering.METHODS:This included 49 eyes that received conventional ICL and 94 eyes that received Hole ICL.The eyes that received Hole ICL were divided into three groups according to the degree of decentering:group 1,central hole within 1 hole diameter(HD) from the pupil center;group 2,central hole within 1 HD to 2 HD;and group 3,central hole within 2 HD to 3 HD.Visual acuity(VA),intraocular pressure(IOP),and spherical equivalent(SE) values were assessed at 1wk,1 and 3mo after surgery.The ocular modulation transfer function,Strehl ratio,objective scattering index,and higher order aberrations(HOAs) were measured for 4-mm pupils at 3mo after surgery.RESULTS:There were no significant differences in VA,IOP,and SE among the conventional and Hole ICL groups.With regard to HOAs,values for coma and spherical aberrations showed no differences.The total HOA and trefoil values were significantly higher in group 2 than in group 1(P=0.02,0.03,respectively).There were no significant differences among groups with regard to other optical quality parameter at 3mo after surgery.CONCLUSION:Our results suggest that Hole ICL implantation provides satisfactory visual quality that is equivalent to that provided by conventional ICL,regardless of the presence of central hole and degree of decentering. | Min Ji Park Hye Min Jeon Kyoung Heon Lee Sang Youp Han | 2017 | International Journal of Ophthalmology(English edition)2017，10，4： | 7 |
| 18 | Outcome of transarterial chemoembolization-based multi-modal treatment in patients with unresectable hepatocellular carcinoma显示文摘AIM:To investigate the efficacy and safety of transarterial chemoembolization(TACE)-based multimodal treatment in patients with large hepatocellular carcinoma(HCC).METHODS:A total of 146 consecutive patients were included in the analysis,and their medical records and radiological data were reviewed retrospectively.RESULTS:In total,119 patients received TACE-based multi-modal treatments,and the remaining 27 received conservative management.Overall survival(P<0.001)and objective tumor response(P=0.003)were significantly better in the treatment group than in the conservative group.After subgroup analysis,survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group(P=0.002)but also in the surgical treatment group compared with the loco-regional treatment-only group(P<0.001).Multivariate analysis identified tumor stage(P<0.001)and tumor type(P=0.009)as two independent pre-treatment factors for survival.After adjusting for significant pre-treatment prognostic factors,objective response(P<0.001),surgical treatment(P=0.009),and multi-modal treatment(P=0.002)were identified as independent post-treatment prognostic factors.CONCLUSION:TACE-based multi-modal treatments were safe and more beneficial than conservative management.Salvage surgery after successful downstaging resultedin long-term survival in patients with large,unresectable HCC. | Do Seon Song Soon Woo Nam Si Hyun Bae Jin Dong Kim Jeong Won Jang Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Ho Jong Chun Young Kyoung You Jong Young Choi Seung Kew Yoon | 2015 | World Journal of Gastroenterology2015，21，8： | 7 |
| 19 | Predictors of poor outcomes in patients with wild mushroom-induced acute liver injury显示文摘AIM To identify early predictive markers of poor outcomes in patients with acute liver injury from wild mushroom intoxication.METHODS This observational, retrospective record review involved adults aged ≥ 18 years admitted to emergency department with mushroom intoxication from January 2005 to December 2015. The diagnosis of mushroom intoxication was based on the following:(1) a positive history of recent wild mushroom intake(either raw or cooked);(2) the onset of gastrointestinal symptoms, such as watery diarrhea, vomiting, and/or abdominal pain, after ingestion; and(3) the exclusion of other possible causes of acute liver injury. Acute liver injury was defined by a > 5-fold elevation of liver enzymes or moderate coagulopathy [international normalized ratio(INR) > 2.0]. Clinical and laboratory findings were compared in survivors and non-survivors.RESULTS Of 93 patients with mushroom intoxication, 23, 11 men(47.8%) and 12 women(52.2%), of median age 61 years, developed acute liver injury. The overall inhospital mortality rate was 43.5%(10/23). Among thelaboratory variables, mean serum alkaline phosphatase(73.38 ± 10.89 mg/dL vs 180.40 ± 65.39 mg/dL, P < 0.01), total bilirubin(2.312 ± 1.16 mg/dL vs 7.16 ± 2.94 mg/d L, P < 0.01) concentrations and indirect/direct bilirubin(2.45 ± 1.39 mg/dL vs 0.99 ± 0.45 mg/dL, P < 0.01) ratio as well as prothrombin time(1.88 ± 0.83 mg/dL vs 10.43 ± 4.81 mg/dL, P < 0.01), and activated partial thromboplastin time(a PTT; 32.48 ± 7.64 s vs 72.58 ± 41.29 s, P = 0.01), were significantly higher in non-survivors than in survivors. Logistic regression analysis showed that total bilirubin concentration(OR = 3.58, 95%CI: 1.25-10.22), indirect/direct bilirubin ratio(OR = 0.14, 95%CI: 0.02-0.94) and aP TT(OR = 1.30, 95%CI: 1.04-1.63) were significantly associated with mortality. All patients with total bilirubin > 5 mg/dL or aP TT > 50 s on day 3 died.CONCLUSION Monitoring of bilirubin concentrations and a PTT may help in predicting clinical outcomes in patients with acute liver injury from wild mushroom intoxication. | Taerim Kim Danbi Lee Jae Ho Lee Yoon-Seon Lee Bum Jin Oh Kyoung Soo Lim Won Young Kim | 2017 | World Journal of Gastroenterology2017，23，7： | 7 |
| 20 | Stretchable and colorless freestanding microwire arrays for transparent solar cells with flexibility显示文摘Transparent solar cells(TSCs)are emerging devices that combine the advantages of visible transparency and light-toelectricity conversion.Currently,existing TSCs are based predominantly on organics,dyes,and perovskites;however,the rigidity and color-tinted transparent nature of those devices strongly limit the utility of the resulting TSCs for realworld applications.Here,we demonstrate a flexible,color-neutral,and high-efficiency TSC based on a freestanding form of n-silicon microwires(SiMWs).Flat-tip SiMWs with controllable spacing are fabricated via deep-reactive ion etching and embedded in a freestanding transparent polymer matrix.The light transmittance can be tuned from ~10 to 55% by adjusting the spacing between the microwires.For TSCs,a heterojunction is formed with a p-type polymer in the top portion of the n-type flat-tip SiMWs.Ohmic contact with an indium-doped ZnO film occurs at the bottom,and the side surface has an Al2O3 passivation layer.Furthermore,slanted-tip SiMWs are developed by a novel solventassisted wet etching method to manipulate light absorption.Finite-difference time-domain simulation revealed that the reflected light from slanted-tip SiMWs helps light-matter interactions in adjacent microwires.The TSC based on the slanted-tip SiMWs demonstrates 8%efficiency at a visible transparency of 10% with flexibility.This efficiency is the highest among Si-based TSCs and comparable with that of state-of-the-art neutral-color TSCs based on organic–inorganic hybrid perovskite and organics.Moreover,unlike others,the stretchable and transparent platform in this study is promising for future TSCs. | Sung Bum Kang Ji-Hwan Kim Myeong Hoon Jeong Amit Sanger Chan Ul Kim Chil-Min Kim Kyoung Jin Choi | 2019 | Light(Science & Applications)2019，8，1： | 7 |
