The official scientific journal of the Asian Society of Cardiovascular Imaging (ASCI), Cardiovascular Imaging Asia (CVIA), was successfully launched by the ASCI in 2015. Professor Tae-hoon Kim was the first Editor-in-Chief of this brand new journal. It has continued to be fostered by the current Editor-in-Chief, Professor Sang-Il Choi. Since 2017, the full text of the journal has been available on the CVIA’s website and its influence has further expanded. Ever since CVIA was founded six years ago, the journal has received and published many original scientific research papers, review articles, and expert consensus or guidelines by radiologists, cardiologists, and scientists who have been working in the field of cardiovascular imaging.

The behaviors of LNAPL migration and entrapment in a rough-walled vertical fracture

Bin Lu,Shiqiang Wu,Xinghua Xie,Yefei Tan 한국지질과학협의회 2017 Geosciences Journal Vol.21 No.3

The migration of light non-aqueous phase liquids (LNAPLs) and their entrapment in unsaturated vertical fractures exhibit complex behaviors, such as upward LNAPL migration that follows water level rise. In this study, behavior of LNAPL migration and entrapment in a vertical rough-walled fracture was investigated with optical measurement. A series of experiments were preformed, including fracture drainage, LNAPL infiltration and accumulation in an unsaturated fracture, and upward LNAPL migration with water level rise. Experimental results indicate that the fracture aperture significantly influences the LNAPL migration path and entrapped blobs distribution. The LNAPL-filled aperture follows a normal distribution, with the mean aperture ranging 0.253 mm to 0.287 mm, and the standard deviation around 0.13 mm. The characteristics of the entrapment blob morphology indicate that 80% of the individual blob areas are smaller than 20mm2. The irregular structures of discrete blobs increase the ‘LNAPL-water’ interface, which will exacerbate contamination.

Phosphorus removal and recovery from wastewater by highly efficient struvite crystallization in an improved fluidized bed reactor

Bin Lu,Jingcheng Xu,Ming Zhang,Weihai Pang,Li Xie 한국화학공학회 2017 Korean Journal of Chemical Engineering Vol.34 No.11

Phosphorus is the crucial factor causing eutrophication in the aquatic ecology. The high phosphorus loading in water bodies may result from the direct disposal of untreated wastewater. In this study, a fluidized bed reactor (FBR) was specially developed to remove and recover phosphorus effectively and efficiently via struvite crystallization. Different physiochemical and hydraulic conditions, including hydraulic retention time (HRT), pH, and molar ratios of Mg : P, N: P and Ca :Mg, were explored to optimize the performance of this improved FBR. For the continuous operating trials, promising removal and recovery efficiencies were achieved at the phosphorus concentration of 25.0mg/L: >90% of phosphorus could be removed under the optimum condition (pH=9, HRT=12 h, Mg : P=1.25 and N : P= 7.5). Increasing the recycle flow rate and prolonging the contact time could also enhance the FBR efficiency. The crystal products obtained in FBR were analyzed in terms of composition and structure. Results indicated that almost pure struvite (>99%) was achieved at low calcium concentrations, which could be considered as a high quality fertilizer.

Bin Lu,Changyu Liu,Cong Li 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.1

Informatization has always been one core competency for effective daily management. Although there are various types of management information systems available, few of them could take into account ever changing management requirements of higher vocational colleges. In this paper, we develop a J2EE based management information system for higher vocational colleges. Firstly, we perform an overview of the entire background and situation of the management informatization for higher vocational colleges. Secondly, according to requirement analysis and use case analysis, we divide the system, which requires three roles, i.e., college administrator, enterprise and graduate, into four functional modules, i.e., user login module, college administrator module, graduate module and enterprise module. Thirdly, for architecture design, we adopt a J2EE four-tier architecture, which are user presentation tier, control treatment tier, business logic tier and data persistence tier. Then, we introduce five entities, which are user information table, enterprise information table, graduate information table, recruitment information table and dynamic news table, for the database design. Furthermore, we also illustrate how we implement the final system.

Attenuation of Experimental Autoimmune Hepatitis in Mice with Bone Mesenchymal Stem Cell-Derived Exosomes Carrying MicroRNA-223-3p

Lu, Feng-Bin,Chen, Da-Zhi,Chen, Lu,Hu, En-De,Wu, Jin-Lu,Li, Hui,Gong, Yue-Wen,Lin, Zhuo,Wang, Xiao-Dong,Li, Ji,Jin, Xiao-Ya,Xu, Lan-Man,Chen, Yong-Ping Korean Society for Molecular and Cellular Biology 2019 Molecules and cells Vol.42 No.12

MicroRNA-223-3p (miR-223-3p) is one of the potential microRNAs that have been shown to alleviate inflammatory responses in pre-clinical investigations and is highly encased in exosomes derived from bone mesenchymal stem cells (MSC-exosomes). MSC-exosomes are able to function as carriers to deliver microRNAs into cells. Autoimmune hepatitis is one of the challenging liver diseases with no effective treatment other than steroid hormones. Here, we examined whether MSC-exosomes can transfer miR-223-3p to treat autoimmune hepatitis in an experimental model. We found that MSC-exosomes were successfully incorporated with miR-223-3p and delivered miR-223-3p into macrophages. Moreover, there was no toxic effect of exosomes on the macrophages. Furthermore, treatments of either exosomes or exosomes with miR-223-3p successfully attenuated inflammatory responses in the liver of autoimmune hepatitis and inflammatory cytokine release in both the liver and macrophages. The mechanism may be related to the regulation of miR-223-3p level and STAT3 expression in the liver and macrophages. These results suggest that MSC-exosomes can be used to deliver miR-223-3p for the treatment of autoimmune hepatitis.

( Yi Lu ),( Bin Xu ),( Lu Chen ),( Li Ke Bie ),( Biao Gong ) 대한간학회 2016 Gut and Liver Vol.10 No.3

Background/Aims: To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of symptomatic pancreas divisum (PD) and to discuss whether ERCP procedures and outcomes in younger patients differ from those of adults. Methods: Symptomatic patients with PD were included in the study and divided into underaged (age ≤17 years) and adult (age ≥18 years) group. The clinical information of each patient was reviewed, and then the patients were contacted by telephone or their medical records were reviewed to determine their long-term followup outcomes. Results: A total of 141 procedures were performed in 82 patients (17 underaged and 65 adult patients). The ERCP indications included abdominal pain (39.02%), pancreatitis (12.20%), recurrent pancreatitis (36.59%), and other discomfort (12.20%). The endoscopic interventions included endoscopic pancreatic sphincterotomy in 44.68% of the patients, bouginage in 26.95%, pancreatic ductal stone extraction in 19.15%, endoscopic nasopancreatic drainage in 21.99%, and endoscopic retrograde pancreatic drainage in 56.74%. After a median follow-up of 41 months, the overall response rate was 62.32%. Between the underaged group and the adult group, significant differences were not observed in the ERCP procedures, complications and longterm follow-up results. Conclusions: ERCP is a safe and effective treatment for symptomatic PD. Based on the details, complications, and follow-up results, the ERCP procedure did not present differences between the underaged and adult groups. (Gut Liver 2016;10:476-482)

Hui-bin Lu,Peng Xing,Lei Zhai,Dorji Phurbu,Qian Tang,Qing-long Wu 한국미생물학회 2018 The journal of microbiology Vol.56 No.7

Strains pyc13T and ZGT13 were isolated from Lake Pengyan and Lake Zigetang on Tibetan Plateau, respectively. Both strains were Gram-negative, catalase- and oxidase-positive, aerobic, rod-shaped, nonmotile, and nonflagellated bacteria. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains pyc13T and ZGT13 belong to the genus Halomonas, with Halomonas alkalicola 56-L4-10aEnT as their closest neighbor, showing 97.4% 16S rRNA gene sequence similarity. The predominant respiratory quinone of both strains was Q-9, with Q-8 as a minor component. The major fatty acids of both strains were C18:1 ω6c/C18:1 ω7c, C16:1 ω6c/C16:1 ω7c, C16:0, and C12:0 3OH. The polar lipids of both strains consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, glycolipid, phospholipids of unknown structure containing glucosamine, and unidentified phospholipids. The DNA G + C content of pyc13T and ZGT13 were 62.6 and 63.4 mol%, respectively. The DNA-DNA hybridization values of strain pyc13T were 34, 41, 61, 35, and 35% with the reference strains H. alkalicola 56-L4-10aEnT, H. sediminicola CPS11T, H. mongoliensis Z-7009T, H. ventosae Al12T, and H. fontilapidosi 5CRT, respectively. Phenotypic, biochemical, genotypic, and DNA-DNA hybridization data showed that strains pyc13T and ZGT13 represent a new species within the genus Halomonas, for which the name H. tibetensis sp. nov. is proposed. The type strain is pyc13T (= CGMCC 1.15949T = KCTC 52660T).
