| 1 | REE geochemistry of suspended sediments from the rivers around the Yellow Sea and provenance indicators显示文摘Rare earth element (REE) compositions of the suspended sediments from the rivers around the Yellow Sea were different in that Korean river sediments (Han, Keum and Yeongsan Rivers) yield stronger fractionations than Chinese river sediments (Changjiang, Huanghe and Yalujiang), shown by obvious enrichments of LREE (light rare earth element) relative to UCC (upper continental crust). Variations of source rock compositions in the drainage basins are responsible for the differences of REE compositions between the river sediments. REE fractionation parameters including (La/Yb)UCC and (Gd/Yb)UCC as well as the ratios of La/Sc and Th/Sc can be treated as proper proxies for identifying the Chinese river sediments from those Korean river matters, and furthermore, for studying the provenances and paleoenvironmental changes of the marginal seas of China. | YANG Shouye LI Congxian C.

| 2 | Early expressions of hypoxia-inducible factor 1alpha and vascular endothelial growth factor increase the neuronal plasticity of activated endogenous neural stem cells after focal cerebral ischemia显示文摘Endogenous neural stem cells become 'activated' after neuronal injury, but the activation sequence and fate of endogenous neural stem cells in focal cerebral ischemia model are little known. We evaluated the relationships between neural stem cells and hypoxia-inducible factor-1α and vascular endothelial growth factor expression in a photothromobotic rat stroke model using immunohistochemistry and western blot analysis. We also evaluated the chronological changes of neural stem cells by 5-bromo-2′-deoxyuridine(BrdU) incorporation. Hypoxia-inducible factor-1α expression was initially increased from 1 hour after ischemic injury, followed by vascular endothelial growth factor expression. Hypoxia-inducible factor-1α immunoreactivity was detected in the ipsilateral cortical neurons of the infarct core and peri-infarct area. Vascular endothelial growth factor immunoreactivity was detected in bilateral cortex, but ipsilateral cortex staining intensity and numbers were greater than the contralateral cortex. Vascular endothelial growth factor immunoreactive cells were easily found along the peri-infarct area 12 hours after focal cerebral ischemia. The expression of nestin increased throughout the microvasculature in the ischemic core and the peri-infarct area in all experimental rats after 24 hours of ischemic injury. Nestin immunoreactivity increased in the subventricular zone during 12 hours to 3 days, and prominently increased in the ipsilateral cortex between 3–7 days. Nestin-labeled cells showed dual differentiation with microvessels near the infarct core and reactive astrocytes in the peri-infarct area. BrdU-labeled cells were increased gradually from day 1 in the ipsilateral subventricular zone and cortex, and numerous BrdU-labeled cells were observed in the peri-infarct area and non-lesioned cortex at 3 days. BrdU-labeled cells rather than neurons, were mainly co-labeled with nestin and GFAP. Early expressions of hypoxia-inducible factor-1α and vascular endothelial growth factor after ischemia made up the microenvironment to increase the neuronal plasticity of activated endogenous neural stem cells. Moreover, neural precursor cells after large-scale cortical injury could be recruited from the cortex nearby infarct core and subventricular zone. | Seung Song Jong-Tae Park Joo Young Na Man-Seok Park Jeong-Kil Lee Min-Cheol Lee Hyung-Seok Kim | 2014 | Neural Regeneration Research2014，9，9： | 17 |
| 3 | The dynamics of the piglet gut microbiome during the weaning transition in association with health and nutrition显示文摘Background: Understanding the composition of the microbial community and its functional capacity during weaning is important for pig production as bacteria play important roles in the pig's health and growth performance. However,limited information is available regarding the composition and function of the gut microbiome of piglets in early-life.Therefore, we performed 16 S rRNA gene and whole metagenome shotgun sequencing of DNA from fecal samples from healthy piglets during weaning to measure microbiome shifts, and to identify the potential contribution of the early-life microbiota in shaping piglet health with a focus on microbial stress responses, carbohydrate and amino acid metabolism.Results: The analysis of 16 S rR NA genes and whole metagenome shotgun sequencing revealed significant compositional and functional differences between the fecal microbiome in nursing and weaned piglets. The fecal microbiome of the nursing piglets showed higher relative abundance of bacteria in the genus Bacteroides with abundant gene families related to the utilization of lactose and galactose. Prevotel a and Lactobacil us were enriched in weaned piglets with an enrichment for the gene families associated with carbohydrate and amino acid metabolism. In addition, an analysis of the functional capacity of the fecal microbiome showed higher abundances of genes associated with heat shock and oxidative stress in the metagenome of weaned piglets compared to nursing piglets.Conclusions: Overal, our data show that microbial shifts and changes in functional capacities of the piglet fecal microbiome resulted in potential reductions in the effects of stress, including dietary changes that occur during weaning.These results provide us with new insights into the piglet gut microbiome that contributes to the growth of the animal. | Robin B.Guevarra Sang Hyun Hong Jin Ho Cho Bo-Ra Kim Jiwon Shin Jun Hyung Lee Bit Na Kang Young Hwa Kim Suphot Wattanaphansak Richard E.Isaacson Minho Song Hyeun Bum Kim | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 16 |
| 4 | The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence. | Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，8： | 14 |
| 5 | Piglet gut microbial shifts early in life:causes and effects显示文摘The gut microbiome has long been known to play fundamentally important roles in the animal health and the well-being of its host. As such, the establishment and maintenance of a beneficial gut microbiota early in life is crucial in pigs, since early gut colonizers are pivotal in the establishment of permanent microbial community structures affecting the health and growth performance of pigs later in life. Emphasizing this importance of early gut colonizers, it is critical to understand the factors impacting the establishment of the piglet gut microbiome at weaning. Factors include, among others, diet, in-feed antibiotics, probiotics and prebiotic administration. The impact of these factors on establishment of the gut microbiome of piglets at weaning includes effects on piglet gut microbial diversity, structure, and succession. In this review, we thoroughly reviewed the most recent findings on the piglet gut microbiome shifts as influenced by weaning, and how these microbiome changes brought about by various factors that have been shown to affect the development of microbiota in piglets. This review will provide a general overview of recent studies that can help to facilitate the design of new strategies to modulate the gut microbiome in order to enhance gastrointestinal health, growth performance and well-being of piglets. | Robin B.Guevarra Jun Hyung Lee Sun Hee Lee Min-Jae Seok Doo Wan Kim Bit Na Kang Timothy J.Johnson Richard E.Isaacson Hyeun Bum Kim | 2019 | Journal of Animal Science and Biotechnology2019，10，3： | 13 |
| 6 | Pretreated quercetin protects gerbil hippocampal CA1 pyramidal neurons from transient cerebral ischemic injury by increasing the expression of antioxidant enzymes显示文摘Quercetin(QE; 3,5,7,3′,4′-pentahydroxyflavone), a well-known flavonoid, has been shown to prevent against neurodegenerative disorders and ischemic insults. However, few studies are reported regarding the neuroprotective mechanisms of QE after ischemic insults. Therefore, in this study, we investigated the effects of QE on ischemic injury and the expression of antioxidant enzymes in the hippocampal CA1 region of gerbils subjected to 5 minutes of transient cerebral ischemia. QE was pre-treated once daily for 15 days before ischemia. Pretreatment with QE protected hippocampal CA1 pyramidal neurons from ischemic injury, which was confirmed by neuronal nuclear antigen immunohistochemistry and Fluoro-Jade B histofluorescence staining. In addition, pretreatment with QE significantly increased the expression levels of endogenous antioxidant enzymes Cu/Zn superoxide dismutase, Mn superoxide dismutase, catalase and glutathione peroxidase in the hippocampal CA1 pyramidal neurons of animals with ischemic injury. These findings demonstrate that pretreated QE displayed strong neuroprotective effects against transient cerebral ischemia by increasing the expression of antioxidant enzymes. | Bai Hui Chen Joon Ha Park Ji Hyeon Ahn Jeong Hwi Cho In Hye Kim Jae Chul Lee Moo-Ho Won Choong-Hyun Lee In Koo Hwang Jong-Dai Kim Il Jun Kang Jun Hwi Cho Bich Na Shin Yang Hee Kim Yun Lyul Lee Seung Min Park | 2017 | Neural Regeneration Research2017，12，2： | 9 |
| 7 | 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 |

| 9 | Thin films as an emerging platform for drug delivery显示文摘Pharmaceutical scientists throughout the world are trying to explore thin films as a novel drug delivery tool. Thin films have been identified as an alternative approach to conventional dosage forms. The thin films are considered to be convenient to swallow, selfadministrable, and fast dissolving dosage form, all of which make it as a versatile platform for drug delivery. This delivery system has been used for both systemic and local action via several routes such as oral, buccal, sublingual, ocular, and transdermal routes. The design of efficient thin films requires a comprehensive knowledge of the pharmacological and pharmaceutical properties of drugs and polymers along with an appropriate selection of manufacturing processes. Therefore, the aim of this review is to provide an overview of the critical factors affecting the formulation of thin films, including the physico-chemical properties of polymers and drugs, anatomical and physiological constraints, as well as the characterization methods and quality specifications to circumvent the difficulties associated with formulation design. It also highlights the recent trends and perspectives to develop thin film products by various companies. | Sandeep Karki Hyeongmin Kim Seon-Jeong Na Dohyun Shin Kanghee Joa Jaehwi Lee | 2016 | Asian Journal of Pharmaceutical Sciences2016，11，5： | 6 |
| 10 | Streptococcus mutans activates the AIM2, NLRP3 and NLRC4 inflammasomes in human THP-1 macrophages显示文摘Streptococcus mutans(S. mutans), a major aetiologic agent of dental caries, is involved in systemic diseases, such as bacterial endocarditis, if it enters the bloodstream through temporary bacteraemia. Interleukin(IL)-1β, a proinflammatory cytokine, is related to the host defences against pathogens, and its synthesis, maturation, and secretion are tightly regulated by the activation of the inflammasome, an inflammatory signalling complex. This study examined the signalling mechanism of IL-1β secretion and the inflammasome pathway induced by S. mutans to explain the molecular mechanism through which systemic infection by oral streptococci can occur. After infection of THP-1 cells with S. mutans, the expression of inflammasome components was detected using various methods. S. mutans induced IL-1β secretion via caspase-1 activation, and S. mutans-induced IL-1β secretion required absent in melanoma(AIM2), NLR family pyrin domain-containing 3(NLRP3) and NLR family CARD domain-containing 4(NLRC4)inflammasome activation. In particular, the S. mutans-induced NLRP3 inflammasome was mediated by adenosine triphosphate(ATP) release, potassium depletion and lysosomal damage. Our study provides novel insight into the innate immune response against S. mutans infection. | Yuri Song Hee Sam Na Eunjoo Park Mi Hee Park Hyun Ah Lee Jin Chung | 2018 | International Journal of Oral Science2018，10，3： | 6 |

| 12 | Inflammatory markers as selection criteria of hepatocellular carcinoma in living-donor liver transplantation显示文摘AIM:To investigate that inflammatory markers can predict accurately the prognosis of hepatocelluar carcinoma(HCC)patients in living-donor liver transplantation(LDLT).METHODS:From October 2000 to November 2011,224 patients who underwent living donor liver transplantation for HCC at our institution were enrolled in this study.We analyzed disease-free survival(DFS)and overall survival(OS)after LT in patients with HCC and designed a new score model using pretransplant neutrophil-lymphocyte ratio(NLR)and C-reactive protein(CRP).RESULTS:The DFS and OS in patients with an NLR level≥6.0 or CRP level≥1.0 were significantly worse than those of patients with an NLR level<6.0 or CRP level<1.0(P=0.049,P=0.003 for NLR and P=0.010,P<0.001 for CRP,respectively).Using a new score model using the pretransplant NLR and CRP,we can differentiate HCC patients beyond the Milan criteria with agood prognosis from those with a poor prognosis.CONCLUSION:Combined with the Milan criteria,new score model using NLR and CRP represent new selection criteria for LDLT candidates with HCC,especially beyond the Milan criteria. | Gun Hyung Na Dong Goo Kim Jae hyun Han Eun Young Kim Soo Ho Lee Tae Ho Hong Young Kyoung You | 2014 | World Journal of Gastroenterology2014，20，21： | 6 |
| 13 | Association between hepatocellular carcinoma and tumor necrosis factor alpha polymorphisms in South Korea显示文摘AIM: To investigate associations between the tumor necrosis factor alpha(TNF-α)-1031 T>C,-863 C>A,-857 C>T,-308 G>A,and-238 G>A polymorphisms and HCC in Korea.METHODS: Hepatocellular carcinoma(HCC) cases were diagnosed at CHA Bundang Medical Center from June 1996 to August 2008. The association between TNF-α polymorphisms and HCC was analyzed in 157HCC patients and 201 controls using a polymerase chain reaction-restriction fragment length polymorphism assay. We investigated five TNF-α polymorphisms,which are TNF-α-1031 T>C,-863 C>A,-857 C>T,-308 G>A,and-238 G>A. The TNF-α genotype frequencies,genotype combinations and haplotypes were analyzed to disclose the association with HCC.RESULTS: None of the TNF-α polymorphisms was significantly associated with HCC. However,nine genotype combinations had associations with increased likelihood of HCC. Among them,TNF-α-1031/-857/-238 TT/CC/GA(AOR = 18.849,95%CI: 2.203-161.246,P = 0.007),TNF-α-1031/-308/-238 TT/GG/GA(AOR = 26.956,95%CI: 3.071-236.584,P = 0.003),and TNF-α-1031/-238 TT/GA(AOR = 21.576,95%CI: 2.581-180.394,P = 0.005) showed marked association with HCC. There were five haplotypes of TNF-α polymorphisms which were significantly associated with HCC. They are TNF-α-1031/-863/-857/-308/-238 T-C-C-G-A(OR = 25.824,95%CI: 1.491-447.223,P = 0.0005),TNF-α-1031/-857/-308/-238 T-C-G-A(OR = 12.059,95%CI: 2.747-52.950,P < 0.0001),TNF-α-1031/-857/-238 T-C-A(OR = 10.696,95%CI: 2.428-47.110,P = 0.0001),TNF-α-1031/-308/-238 T-G-A(OR = 7.556,95%CI: 2.173-26.280,P = 0.0002) and TNF-α-1031/-238 T-A(OR = 10.865,95%CI: 2.473-47.740,P = 0.0001). Moreover,HCC Okuda stage Ⅲ cases with the TNF-α-1031 CC genotype had better survival than those with the TT genotype(AOR = 5.795,95%CI: 1.145-29.323). CONCLUSION: Although no single TNF-α polymorphism is associated with HCC in this study,some TNF-α genotype combinations and haplotypes are associated with HCC. In addition,HCC Okuda stage Ⅲ cases with the TNF-α-1031 TT genotype may have a better prognosis than those with the CC genotype. | Suk Pyo Shin Nam Keun Kim Ju Hwan Kim Ju Ho Lee Jung Oh Kim Sung Hwan Cho Hana Park Mi Na Kim Kyu Sung Rim Seong Gyu Hwang | 2015 | World Journal of Gastroenterology2015，21，46： | 5 |
| 14 | Temporal pattern of resolution/recurrence of choroidal neovascularization during bevacizumab therapy for wet age-related macular degeneration显示文摘AIM:To characterize temporal pattern of resolution and recurrence of naive choroidal neovascularization(CNV) secondary to wet age-related macular degeneration(AMD) treated with intravitreal bevacizumab on as needed regimen,and to analyze baseline risk factors for CNV resolution or recurrence.METHODS:Ninety-one eyes of 80 patients with newly diagnosed wet AMD were retrospectively studied.All eyes were treated with a round of three monthly intravitreal bevacizumab injections,followed by one additional 'bonus' injection after resolution of CNV activity.During follow-up,eyes were monitored with fluorescein angiography,optical coherence tomography,and best-corrected visual acuity(BCVA).In case of recurrences of CNV activity,eyes were retreated with other rounds of bevacizumab injections following the same treatment protocol.RESULTS:Over a median follow-up of 532d,the median resolution time of CNV activity in the first,second,and third treatment round was 98d,126d,and 111d,respectively.The median recurrence time for the three rounds was 154d,126d,and 151d,respectively.No significant difference in resolution time(P=0.09) or in recurrence time(P=0.11) was detected among treatment rounds.Age(P=0.0082) and lens status(P=0.035) were found to be associated with CNV resolution;for every 1-year increase in age there was 4% greater chance of CNV resolution;Phakic eyes demonstrated a 33% better chance to experience CNV resolution than pseudophakic eyes.For CNV recurrence,lens status(P=0.0009) and gender(P=0.0446) were found to be predictive;pseudophakic eyes had a 3.69-fold greater risk to experience recurrence of CNV activity compared to phakic eyes;males had a 2.19-fold greater risk to experience recurrence of CNV activity than females.No significant BCVA changes among three treatment rounds were noted(P=0.56).CONCLUSION:Resolution time and recurrence time of CNV activity were not significantly different among treatment rounds,suggesting absence of tachyphylaxis to bevacizumab.A cautious decision should be made upon discontinuing treatment in wet AMD eyes of younger or pseudophakic patients,which showed slower response to bevacizumab.In addition,wet AMD eyes of male or pseudophakic patients should be evaluated more carefully after stopping the treatment,because they may have early reactivation of the CNV.BCVA was preserved by bevacizumab treatment despite multiple recurrences. | Haiyan Wang Giulio Barteselli William R.Freeman Su Na Lee Jay Chhablani Sharif El-Emam Lingyun Cheng | 2013 | International Journal of Ophthalmology(English edition)2013，6，5： | 5 |

| 17 | Clinical implications of neutrophil-to-lymphocyte ratio and MDSC kinetics in gastric cancer patients treated with ramucirumab plus paclitaxel显示文摘Objective: We aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio(NLR) and myeloidderived suppressor cells(MDSCs) in gastric cancer patients treated with second-line ramucirumab plus paclitaxel.Methods: A total of 116 patients with advanced or metastatic gastric cancer who receive ramucirumab plus paclitaxel were prospectively enrolled. Fresh blood samples were collected before and after treatment, and flow cytometry was performed to assess the proportions of monocytic(m MDSCs) and granulocytic MDSCs(g MDSCs).Results: Median age was 58 years and 71(61.2%) patients were male. A baseline NLR≥2.94 was associated with significantly poorer progression-free survival(PFS) and overall survival(OS) vs. an NLR<2.94(P=0.011 and P=0.002, respectively). In multivariate analysis, an NLR≥2.94 was independently associated with poorer PFS[hazard ratio(HR)=1.58;95% confidence interval(95% CI): 1.01-2.49, P=0.046] and OS(HR=1.77;95% CI:1.04-3.04, P=0.036). While m MDSC counts did not significantly change following two cycles of therapy(P=0.530),g MDSC counts decreased significantly after two treatment cycles(P=0.025) but tended to increase in patients with progressive disease after two treatment cycles(P=0.098). A progressive increase in g MDSC counts(≥44%) was associated with a significantly shorter PFS and OS vs. a g MDSC count increase <44%(P=0.001 and P=0.003,respectively).Conclusions: The baseline NLR may help guide clinical decisions during ramucirumab plus paclitaxel therapy for gastric cancer. Our g MDSC kinetics data warrant further clinical validation and mechanistic investigation. | Hyung-Don Kim Min-Hee Ryu Sangsoon Yoon Young-Soon Na Meesun Moon Hyungeun Lee Hyung Geun Song Yoon-Koo Kang | 2020 | Chinese Journal of Cancer Research2020，32，5： | 4 |
| 18 | Differential diagnoses of magnetic resonance imaging for suspected acute appendicitis in pregnant patients显示文摘BACKGROUND: Accurate and timely diagnosis of acute surgical disease in pregnant patient is chal enging. Although magnetic resonance imaging(MRI) is the most accurate modality to diagnose acute appendicitis in pregnant patients, it is often used as a last resort because of high cost and long scan time. We performed this study to analyze differential diagnoses of appendix MRI and to investigate if there are any blood tests that can predict surgical condition in pregnant patients.METHODS: A retrospective, cross-sectional study was conducted on 46 pregnant patients who underwent non-enhanced appendix MRI in suspicion of acute appendicitis from 2010 to 2016. Differential diagnoses of appendix MRI were analyzed and blood tests were compared between those who had surgical and non-surgical disease.RESULTS: Appendix MRI differentiated two surgical disease; acute appendicitis and ovarian torsion; and various non-surgical conditions such as uterine myoma, hydronephrosis, ureterolithiasis and diverticulitis among clinically suspected acute appendicitis in pregnancy. The diagnostic accuracy of MRI for acute appendicitis in this study was 93.5%. Patients who had surgical disease showed significantly higher WBC count(≥11,000/mm^3), proportion of neutrophils in the WBC(≥79.9%), neutrophil-to-lymphocyte ratio(NLR≥6.4), levels of C-reactive protein(CRP≥1.82 mg/dL) and bilirubin(≥0.66 mg/dL) than those who had non-surgical disease.CONCLUSION: MRI can reliably differentiate surgical conditions and several blood tests(WBC, proportion of neutrophils in the WBC, NLR, CRP, bilirubin) can help anticipate acute surgical condition among pregnant patients suspected to have acute appendicitis. | Ji Yong Jung Ji Ung Na Sang Kuk Han Pil Cho Choi Jang Hee LEE Dong Hyuk Shin | 2018 | World Journal of Emergency Medicine2018，9，1： | 4 |

| 20 | Searching for the Nano-Hertz Stochastic Gravitational Wave Background with the Chinese Pulsar Timing Array Data ReleaseⅠ显示文摘Observing and timing a group of millisecond pulsars with high rotational stability enables the direct detection of gravitational waves(GWs).The GW signals can be identified from the spatial correlations encoded in the times-of-arrival of widely spaced pulsar-pairs.The Chinese Pulsar Timing Array(CPTA)is a collaboration aiming at the direct GW detection with observations carried out using Chinese radio telescopes.This short article serves as a“table of contents”for a forthcoming series of papers related to the CPTA Data Release 1(CPTA DR1)which uses observations from the Five-hundred-meter Aperture Spherical radio Telescope.Here,after summarizing the time span and accuracy of CPTA DR1,we report the key results of our statistical inference finding a correlated signal with amplitude logA_(c)=-14.4_(-2.8)^(+1.0)for spectral index in the range ofα∈[-1.8,1.5]assuming a GW background(GWB)induced quadrupolar correlation.The search for the Hellings–Downs(HD)correlation curve is also presented,where some evidence for the HD correlation has been found that a 4.6σstatistical significance is achieved using the discrete frequency method around the frequency of 14 n Hz.We expect that the future International Pulsar Timing Array data analysis and the next CPTA data release will be more sensitive to the n Hz GWB,which could verify the current results. | Heng Xu Siyuan Chen Yanjun Guo Jinchen Jiang Bojun Wang Jiangwei Xu Zihan Xue RNicolas Caballero Jianping Yuan Yonghua Xu Jingbo Wang Longfei Hao Jingtao Luo Kejia Lee Jinlin Han Peng Jiang Zhiqiang Shen Min Wang Na Wang Renxin Xu Xiangping Wu Richard Manchester Lei Qian Xin Guan Menglin Huang Chun Sun Yan Zhu | 2023 | Research in Astronomy and Astrophysics2023，23，7： | 3 |
