| 1 | Functional analysis of the larval serum protein gene promoter from silkworm,Bombyx mori.显示文摘The regulation region of larval serum protein gene, Bombyx mori. (BmLSP), consisting of the first intron, the first exon, the central promoter region and 5′-upstream region, is cloned from genomic DNA from the silkworm va-riety of Suju譓inghu. Using PCR and restriction endonu-clease methods, a series of luciferase reporter plasmids, driven by different length of BmLSP promoters, are con-structed. Via the transient expression system in BmN cells, the effects of the regulation elements and foreign insect hor-mones on the BmLSP promoter activity are investigated. The results demonstrate that the promoter activity of BmLSP is 5.8- or 4.4-fold higher than that of BmLSPs whose first in-tron or the element in 5′-upstream region harboring the homologous sequence with the first intron of light-chain fib-roin gene (EHIF) is deleted, respectively, suggesting that both the first intron and EHIF contain the main positive cis-acting elements. However, the inactive mariner transposable ele-ment (MTE) in 5′-upstream region presents a negative effect. Furthermore, the effects of juvenile hormone analogue (JHA) on the BmLSP promoter activity show a typical dose-dependent manner, that is, low concentration treat-ments increase the BmLSP promoter activity and high con-centration treatments decrease it. Meanwhile, insect ecdy-sone (MH) treatments present no significant effect. | TANG Shunming, YI Yongzhu, SHEN Xingjia, ZHANG Zhifang, LI Yiren & HE Jialu Key Laboratory of Silkworm Biotechnology, Ministry of Agriculture, Sericultural Research Institute, Chinese Academy of Agricultural Sci-ences, Zhenjiang 212018, China Correspondence should be addressed to Zhang Zhifang (e-mail: zjsbsri@ public.zj.js.cn) | 2003 | Chinese Science Bulletin2003，48，23： | 13 |

| 3 | IFN-γ,establishes interferon-stimulated gene-mediated antiviral state against Newcastle disease virus in chicken fibroblasts显示文摘Newcastle disease virus(NDV)causes severe economic losses through severe morbidity and mortality and poses a significant threat to the global poultry industry.Significant efforts have been made to develop novel vaccines and therapeutics;however,the interaction of NDV with the host is not yet fully understood.Interferons(IFNs),an integral component of innate immune signaling,act as the first line of defense against invading viruses.Compared with the mammalian repertoire of IFNs,limited information is available on the antiviral potential of IFNs in chickens.Here,we expressed chicken IFN-γ(chlFN-γ)using a baculovirus expression vector system,characterized its antiviral potential against NDV,and determined its antiviral potential.Priming of chicken embryo fibroblasts with chlFN-γelicited an antiviral environment in primary cells,which was mainly due to interferon-stimulated genes(ISGs).A genome-wide transcriptomics approach was used to elucidate the possible signaling pathways associated with IFN-γ-induced immune responses.RNA-sequencing(RNA-seq)data revealed significant induction of ISG-associated pathways,activated temporal expression of ISGs,antiviral mediators,and transcriptional regulators in a cascade of antiviral responses.Collectiv(e)ly,we found that IFN-γsignificantly elicited an antiviral response against NDV infection.These data provide a foundation for chlFN-γ-mediated antiviral responses and underpin functional annotation of these important chlFN-γ,-induced antiviral influencers. | Xin Yang Mehboob Arslan Xingjian Liu Haozhi Song Mengtan Du YinüLi Zhifang Zhang | 2020 | Acta Biochimica et Biophysica Sinica2020，52，3： | 9 |

| 6 | Determination of rare earth elements in plant protoplasts by MAA显示文摘A preliminary study on the speciation of rare earth elements in plant cells has been carried out by molecular activation analysis (MAA). Mesophyll protoplasts of Brassica napus were isolated by enzymatic digestion. After being washed with isosmotic solution containing EDTA for several times, the protoplasts were purified by gradient centrifugation. Then the concentration of rare earth elements (REEs) in the protoplasts was determined by neutron activation analysis. The result shows that REEs can enter the cells of the plant. | ZHANG Zhiyong WANG Yuqi SUN Jingxin LI Fuliang CHAI Zhifang XU Lei LI Xin CAO Guoyin | 2000 | Chinese Science Bulletin2000，45，16： | 8 |
| 7 | Dynamic changes in proteins during apple(Malus x domestica)fruit ripening and storage显示文摘A proteomic study,using two-dimensional polyacrylamide gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight,was conducted in apple fruit(cv.‘Golden Delicious’)starting at 10 days prior to harvest through 50 days in storage.Total protein was extracted using a phenol/sodium dodecyl sulfate protocol.More than 400 protein spots were detected in each gel and 55 differentially expressed proteins(p,0.05)were subjected to matrix-assisted laser desorption/ionization time-of-flight/time-of-flight analysis.Fifty-three of these proteins were finally identified using an apple expressed sequence tag database downloaded from Genome Database for Rosaceae and placed into six categories.The categories and the percentage of proteins placed in each category were stress response and defense(49.0%),energy and metabolism(34.0%),fruit ripening and senescence(5.6%),signal transduction(3.8%),cell structure(3.8%)and protein synthesis(3.8%).Proteins involved in several multiple metabolic pathways,including glycolysis,pentose–phosphate pathway,anti-oxidative systems,photosynthesis and cell wall synthesis,were downregulated,especially during the climacteric burst in respiration and during the senescent stages of fruit development.Proteins classified as allergens or involved in cell wall degradation were upregulated during the ripening process.Some protein spots exhibited a mixed pattern(increasing to maximal abundance followed by a decrease),such as 1-aminocyclopropane-1-carboxylate oxidase,L-ascorbate peroxidase and abscisic acid response proteins.The identification of differentially expressed proteins associated with physiological processes identified in the current study provides a baseline of information for understanding the metabolic processes and regulatory mechanisms that occur in climacteric apple fruit during ripening and senescence. | Yun Shi Li Jiang Li Zhang Ruoyi Kang Zhifang Yu | 2014 | Horticulture Research2014，1，1： | 8 |
| 8 | QTL analysis of ear leaf traits in maize(Zea mays L.)under different planting densities显示文摘Modem maize varieties have become more productive than ever, owing largely to increased tolerance of high plant density. However, the genetics of ear leaf traits under different densities remains poorly understood. In this study, Zhongdan 909 recombinant inbred lines(RILs) derived from a cross between Z58 and HD568 were genotyped for 3072 single-nucleotide polymorphisms(SNPs), and phenotyped for leaf length(LL), leaf width(LW), and leaf angle(LA) of the uppermost ear leaf under three planting densities(52,500,67,500, and 82,500 plants ha-1, respectively). A genetic map was then constructed using1358 high-quality SNPs. The total length of the linkage map was 1985.2 cM and the average interval between adjacent markers 1.46 cM. With increasing density, LL and LW decreased from 63.68 to 63.02 cm and from 8.56 to 8.21 cm, respectively, while LA increased from19.42° to 19.66°. All three traits had high heritabilities, of 0.75, 0.78, and 0.84, respectively.Using inclusive composite interval mapping, 23, 25, and 17 quantitative trait loci(QTL) were detected for LL, LW, and LA, respectively. Of these, 35 were simultaneously detected under two or three plant densities, while 30 were detected under only one. Sixty-five individual QTL explained 2.41% to 16.53% of phenotypic variation, while eight accounted for >10%.These findings will help us understand the genetic basis of leaf traits in maize as well as the response of maize to increased plant density. | Hongwu Wang Qianjin Liang Kun Li Xiaojiao Hu Yujin Wu Hui Wang Zhifang Liu Changling Huang | 2017 | The Crop Journal2017，5，5： | 7 |
| 9 | Recent progress of fully synthetic carbohydrate-based vaccine using TLR agonist as build-in adjuvant显示文摘Fully synthetic vaccine, in which one or multi-molecular antigens are conjugated to a synthetic carrier with well-defined chemical structure, is a new direction to develop carbohydrate-based vaccine against cancer and pathogens. Toll like receptor(TLR) agonists with the ability to stimulate immune response have been widely investigated and been applied as build-in adjuvants to construct fully synthetic vaccines. In particular, remarkable progress has been achieved in recent years in the development of vaccines constructed with the agonists of TLR1/2, TLR2/6 and TLR4 and tumor-associated carbohydrate antigens(TACAs). These di-, tri-or multi-component vaccine candidates showed attractive immunological properties. This review highlights recent advances in developing full synthetic carbohydrate antigen based vaccines, with an emphasis on the structure-activity relationships that provide a primary basis for future vaccine design and immunotherapy developing. | Zhifang Zhou Hart Lin Chen Li Zhimeng Wu | 2018 | Chinese Chemical Letters2018，29，1： | 6 |
| 10 | Rational design of novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructures for all-solid-state asymmetric supercapacitors显示文摘Constructing graphene-based heterostructures with large interfacial area is an efficient approach to enhance the electrochemical performance of supercapacitors but remains great challenges in their synthesis.Herein,a novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructure(a-Fe_(2)O_(3)NDs/RGO)aerogel was facilely synthesized via excessive metal-ion-induced self-assembly and subsequent calcination route using Prussian blue/graphene oxide(PB/GO)composite aerogel as precursors.The deliberately designed a-Fe_(2)O_(3)NDs/RGO heterostructure offers a highly interconnected porous conductive network,large heterostructure interfacial area,and plenty of accessible active sites,greatly facilitating the electron transfer,electrolyte diffusion,and pseudocapacitive reactions.The obtained a-Fe_(2)O_(3)NDs/RGO aerogel could be used as flexible free-standing electrodes after mechanical compression,which exhibited a significantly enhanced specific capacitance of 347.4 F·g^(-1)at 1 A·g^(-1),extraordinary rate capability of 184 F·g^(-1)at 10 A·g^(-1),and decent cycling stability.With the as-prepared a-Fe_(2)O_(3)NDs/RGO as negative electrodes and the Co_(3)O_(4)NDs/RGO as positive electrodes,an all-solid-state asymmetric supercapacitor(a-Fe_(2)O_(3)NDs/RGO//Co_(3)O_(4)NDs/RGO asymmetric supercapacitor(ASC))was assembled,which delivered a high specific capacitance of 69.1 F·g^(-1)at 1 A·g^(-1)and an impressive energy density of 21.6 W·h·k·g^(-1)at 750 W·k·g^(-1),as well as good cycling stability with a capacity retention of 94.3%after 5,000 cycles.This work provides a promising avenue to design high-performance graphene-based composite electrodes and profound inspiration for developing advanced flexible energy-storage devices. | Chenxiao Wu Zhifang Zhang Zhonghui Chen Zuimin Jiang Huiyu Li Haijing Cao Yongsheng Liu Yanyan Zhu Zebo Fang Xiangrong Yu | 2021 | Nano Research2021，14，4： | 6 |
| 11 | Mesoporous silica SBA-15 functionalized with phosphonate and amino groups for uranium uptake显示文摘Mesoporous silicas have a very attractive ability of sorption and enrichment of metal ions due to their huge surface area and facile functionalization by organic ligands.In this work,phosphonate-amino bifunctionalized mesoporous silica SBA-15(PA-SBA-15) as U(VI) sorbent was fabricated through post-grafting method.The obtained mesoporous silica was characterized by SEM,XRD,NMR and nitrogen sorption/desorption experiments,which revealed the existence of ordered mesoporous structure with uniform pore diameter and large surface area.The adsorptivity of PA-SBA-15 for U(VI) from aqueous solution was investigated using batch sorption technique under different experimental conditions.The preliminary results show that the U(VI) sorption by PA-SBA-15 is very quick with equilibrium time of less than 1 h,and the U(VI) uptake is as large as 373 mg/g at pH 5.5 under 95 ℃.The sorption isotherm has been successfully modeled by the Langmuir isotherm,suggesting a monolayer homogeneous sorption of U(VI) in PA-SBA-15.The sorption is pH-dependent due to the pH-dependent charge of sorbent in the aqueous solution.The thermodynamics research shows that the sorption is a feasible and endothermic process.Based on these results,PA-SBA-15 could be a promising solid phase sorbent for highly-efficient removal of U(VI) ions from waste water and enrichment of U(VI) from a solution at a very low level. | WANG XiaoLiang YUANLiYong WANG YanFei LI ZiJie LIU YaLan FENG YiXiao ZHAO YuLiang CHAI ZhiFang SHI WeiQun | 2012 | Science China Chemistry2012，55，9： | 6 |
| 12 | Effect of lit-moxa stimulation of Guanyuan(CV 4) acupoint on levels of lactic acid and super-oxide dismutase in skeletal muscle of rats显示文摘OBJECTIVE:To observe the effect of lit-moxa stimulating acupoint Guanyuan(CV 4) on lactic acid and super-oxide dismutase(SOD) in skeletal muscle after exercise exhaustion.METHODS:Twenty-eight adult male Sprague-Dawley rats were randomly divided into normal control group,exhausted control group,exercise group and moxibustion group using exercise training and mild heating with lit-moxa stick as treatment methods.The exhausted control group,moxibustion group and exercise group received an exhaustive swimming after 20 days of intervention.Swimming exhausted times were recorded.Lactic acid and SOD concentration in soleus muscle were detected and compared between every two groups.RESULTS:The swimming exhausted times of the moxibustion group and the exercise group were significantly increased compare to the exhausted control group(P < 0.05).The lactic acid of the exhausted control group was significantly increased comparing with the normal control group(P <0.05),and the lactic acid of the moxibustion group and the exercise group were significantly lower than that of the exhausted control group(P < 0.05).The SOD level of the exhausted control group was significantly decreased comparing with the normal control group(P < 0.05),and the SOD level of the moxibustion group and the exercise group were significantly higher than that of the exhausted control group(both,P < 0.05).There was no statistical difference between the moxibustion group and the exercise group.CONCLUSION:With lit moxa stick,heat stimulating acupoint of Guanyuan(CV 4) decreased the levels of lactic acid and SOD in rat's skeletal muscle. | Mo Jie Wu Lili Sun Zhifang Wang Hongbin Ding Na He Long Zhang Lufen Liu Tonghua Li Xiaohong | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 6 |
| 13 | Spatiotemporal variations of nitrate sources and dynamics in a typical agricultural riverine system under monsoon climate显示文摘Nitrogen pollution is a serious environmental issue in the Danjiangkou Reservoir region(DRR),the water source of the South-to-North Water Diversion Project of China.In this research,seasonal surveys and a bi-weekly time series survey were conducted in the Qihe River Basin,one of the most densely populated agricultural basins in the DRR.Hydrochemical compositions(NO3^-Cl^-),dual isotopes(δD-H2O,δ^18O-H2O,δ^15N-NO3^-,andδ^18O-NO3^-),and a Markov Chain Monte Carlo isotope mixing model were jointly applied to unravel the sources,migrations,and transformations of the nitrate(NO3^-)in the basin.It was revealed that the mixing between different sources was the main process controlling the isotopic compositions of the riverine NO3the upper-middle reaches.In contrast,denitrification occurred in the lower reaches.For the first time,the sources of NO3^-quantified at a basin scale in the DRR.Overall,the river transported 484.2 tons/year of NO3^-N to the reservoir,of which 32.6%,36.4%,28.0%,and 3.0%was from soil organic nitrogen,chemical fertilizer,residential sewage and atmospheric precipitation,respectively.The NO3^-N fluxes of the different sources were regulated by the monsoon climate and anthropogenic activities.For example,high precipitation and intense fertilization resulted in severe nonpoint source pollution.Denitrification thrived in soils and reservoirs in wet seasons.Temperature could regulate the migration,nitrification and denitrification processes.Based on the results,we suggest that the management strategies dealing with nitrogen pollution issue in the DRR should follow the specific spatiotemporal characteristics of NO3migration and transformation mechanisms. | Hao Jiang Wenjing Liu Jiangyi Zhang Li Zhou Xiaode Zhou Ke Pan Tong Zhao Yuchen Wang Zhifang Xu | 2020 | Journal of Environmental Sciences2020，32，7： | 5 |
| 14 | Response of the northwestern Pacific upper water δ^(13)C to the last deglacial ventilation of the deep Southern Ocean显示文摘The deglacial δ~13C minimum events that originated from the ventilation of the deep Southern Ocean around Antarctica, have been recorded in a range of marine sediments from the southern to tropical oceans in late Pleistocene. However, the broad δ~13C minimum event was also reported as far as to the northern middle latitudes, in northwestern Pacific marginal sea areas, during the last deglaciation. In the northwestern Pacific, forcing from the northern high latitudes is strongly expressed, while the records of in- fluence from the southern high latitudes are few. The Kuroshio Source Region (KSR) forms a boundary between the northwestern Pacific and the southern, tropical Pacific. So, high-resolution planktonic foraminiferal records in core MD06-3054 from the KSR are well positioned to identify signals from the southern hemisphere in the northwestern Pacific. Planktonic foraminiferal tests from the upper 1030 cm of the core were subject to AMS14C, carbon and oxygen isotopic measurements. A negative excursion was found to occur from about 20.0-6.0 ka BP in δ~13C records of both surface (Globigerinoides ruber) and subsurface (Pulleni- atina obliquiloculata) dwellers, but the overall trends of the two curves have reversed since 26.5 ka BP. Moreover, the δ~13C rec- ord of G. ruber (the surface dweller) shows a robust link to the record of atmospheric CO2, and its changes precede the records of P. obliquiloculata (the subsurface dweller). According to the hydrologic conditions, the broad δ~13C minimum event recorded in the KSR is also a response to the increasing ventilation of the deep Southern Ocean around Antarctica during the last deglaciation. The inconsistency between the records of the surface and subsurface dwellers was possibly caused by the ways that the low δ~13C signal was transmitted. Subsurface water primarily received the low δ~13C signal from the Antarctic Intermediate Water (AAIW), whereas the surface water was probably mainly impacted by atmospheric CO2 in the KSR. The records from the KSR confirm the deduction that the broad δ~13C minimum event in the Okinawa Trough was due to the impact of tropical Pacific surface water dur- ing the last deglaciation, and suggest that signals from the southern high latitudes also can be delivered to the northern middle latitudes. | CHEN ShuangXi LI TieGang TANG Zheng QIU XiaoHua XIONG ZhiFang NAN QingYun XU ZhaoKai CHANG FengMing | 2011 | Chinese Science Bulletin2011，56，24： | 5 |
| 15 | In situ observation of C_(60)(C(COOH)_(2))_(2) interacting with living cells using fluorescence microscopy显示文摘The interactions between nanoparticles and living cells were investigated by an imaging technique of fluorescence microscopy. For this pur- pose, the C60 derivative C60(C(COOH)2)2, a thera- peutic agent for degeneration diseases of central nervous system, was synthesized, purified and characterized. Its interaction with the living cell and penetration of the cellular membrane were in situ studied using the real time imaging technique, and its potential cytotoxicity was also examined by flow cy- tometry. The results indicate that C60(C(COOH)2)2 can easily enter cells, and is mainly located in cytoplasm by fluorescein labeling. Furthermore, C60(C(COOH)2)2 can carry the molecule that cannot cross cellular membranes into cells, because fluo- rescein compound itself cannot enter the cell or ad- here to membrane. At concentrations ranging from 1×10?2 to 1×102 mg/L, C60(C(COOH)2)2 does not show any detectable cytotoxicity. | YE Chang CHEN Chunying CHEN Zhen MENG Huan XING Li JIANG Yaxin YUAN Hui XING Gengmei ZHAO Feng ZHAO Yuliang CHAI Zhifang FANG Xiaohong HAN Dong CHEN Long WANG Chen WEI Taotao | 2006 | Chinese Science Bulletin2006，51，9： | 4 |
| 16 | Carbon performance evaluation model from the perspective of circular economy~The case of Chinese thermal power enterprise显示文摘Carbon emission reduction is the only way to alleviate environmental problems,such as global warming.Effective evaluation of carbon performance can help enterprises to carry out energy saving and emission reduction activities to a certain extent and promote sustainable development.This paper constructs a carbon performance evaluation index system that includes the four dimensions of carbon resource(energy)input,cycle,output,and carbon management by incorporating the principles of circular economy and the theory of resource value circulation from the perspective of the flow trajectory of carbon-containing resources in the circulation of enterprises combined with the production characteristics of thermoelectric enterprises.Subsequently,combined with the case study,this paper discusses the scientific and practical nature of the system and provides another way of thinking for carbon performance evaluation of micro-enterprises in other industries.This paper expands the application boundary of matter-element model and supplements the literature of carbon performance,which has certain theoretical and practical significance. | Zhifang ZHOU Jinhao LIU Huixiang ZENG Mengmeng XU Shihui LI | 2022 | Frontiers of Engineering Management2022，9，2： | 4 |
| 17 | Expression of human soluble TRAIL in Chlamydomonas reinhardtii chloroplast显示文摘Tumor necrosis factor-related apop-tosis-inducing ligand (TRAIL) induces selectively apoptosis in various tumor cells and virus-infected cells, but rarely in normal cells. A chloroplast expres-sion vector, p64TRAIL, containing the cDNA coding for the soluble TRAIL (sTRAIL), was constructed with clpP-trnL-petB-chlL-rpl23-rpl2 as Chlamydomonas reinhardtii plastid homologous recombinant frag-ments and spectinomycin-resistant aadA gene as a select marker. The plasmid p64TRAIL was trans-ferred into the chloroplast genome of C. reinhardtii by the biolistic method. Three independently trans-formed lines were obtained by 100 mg/L spectino-mycin selection. PCR amplification, Southern blot analysis of the sTRAIL coding region DNA and culti-vation cells in the dark all showed that the exogenous DNA had been integrated into chloroplast genome of C. reinhardtii. Western blot analysis showed that human soluble TRAIL was expressed in C. reinhardtii chloroplast. The densitometric analysis of Western blot indicated that the expressed human sTRAIL protein in the chloroplasts of C. reinhardtii accounted for about 0.43%―0.67% of the total soluble proteins. These experimental results demonstrated the possi-bility of using transgenic chloroplasts of green alga as bioreactors for production of biopharmaceuticals. | YANG Zongqi LI yinü CHEN Feng LI Dong ZHANG Zhifang LIU Yanxin ZHENG Dexian WANG Yong SHEN Guifang | 2006 | Chinese Science Bulletin2006，51，14： | 4 |
| 18 | Clemastine rescues behavioral changes and enhances remyelination in the cuprizone mouse model of demyelination显示文摘Increasing evidence suggests that white matter disorders based on myelin sheath impairment may underlie the neuropathological changes in schizophrenia.But it is unknown whether enhancing remyelination is a beneficial approach to schizophrenia.To investigate this hypothesis,we used clemastine,an FDA-approved drug with high potency in promoting oligodendroglial differentiation and myelination,on a cuprizone-induced mouse model of demyelination.The mice exposed to cuprizone(0.2%in chow) for 6 weeks displayed schizophrenia-like behavioral changes,including decreased exploration of the center in the open field test and increased entries into the arms of the Y-maze,as well as evident demyelination in the cortex and corpus callosum.Clemastine treatment was initiated upon cuprizone withdrawal at 10 mg/kg per day for3 weeks.As expected,myelin repair was greatly enhanced in the demyelinated regions with increased mature oligodendrocytes(APC-positive) and myelin basic protein.More importantly,the clemastine treatment rescued the schizophrenia-like behavioral changes in the open field test and the Y-maze compared to vehicle,suggesting a beneficial effect via promoting myelin repair.Our findings indicate that enhancing remyelination may be a potential therapy for schizophrenia. | Zhifang Li Yangtao He Shuangyi Fan Binbin Sun | 2015 | Neuroscience Bulletin2015，31，5： | 4 |
| 19 | Association oftransforming growth factor-β1 gene variants with risk of coal workers'pneumoconiosis显示文摘Objective:The aim of this case-control study was to explore whether five tagging single nucleotide polymorphisms(tSNPs)within the transforming growth factor-β1(TGF-β1)gene were involved in manifestation of inflammatory and fibrotic processes associated with coal workers'pneumoconiosis(CWP).Methods:The study included 508 CWP patients and 526 controls who were underground coal miners from Xuzhou Mining Business Group.Five tSNPs were selected from the HapMap and detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method.Results:The single SNP analysis showed that the genotype frequencies of SNP2(rs1800470,+869T/C,extron 1)and SNP5(rs11466345,intron 5)in CWP cases were sig- nificantly different from those in controls.Multivariate logistic regression analysis revealed that SNP2(rs1800470) CC genotype was associated with decreased risk of CWP(OR=0.50,95%CI=0.32-0.78),which was evident among subgroups of those never smoke(OR=0.40,95%CI=0.24-0.66),cases with stageⅡ(OR=0.41,95%CI =0.22-0.76)and exposure period(<28 y:OR=0.54,95%CI=0.31-0.95;≥28 y:OR=0.52,95%CI=0.32-0.96). However,the SNP5(rs11466345)GG genotype was associated with an increased risk of CWP(OR=2.5,95%CI =1.36-4.57),and further stratification analysis showed that the risk of CWP was increased in both smoking and nonsmoking groups,shorter and longer exposure groups,while the risk of CWP was only increased in patients with stageⅠandⅡ.Conclusion:This study suggests that TGF-β1 polymorphisms may contribute to susceptibility of CWP. | Haiyang Qian Zhifang Song Meilin Wang Xiaomin Jia Aiping Li Ye Yang Lianlian Shen Shasha Wang Chunhui Ni Jianwei Zhou | 2010 | The Journal of Biomedical Research2010，24，4： | 3 |
| 20 | Clinical study of transcatheter occlusion in treating ventricular septal defect combined with right coronary cusp bulge显示文摘Background: Perimembranous ventricular septal defect combined with right coronary cusp bulge generally should be treated with surgical thoracotomy, owing to the potential aortic regurgitation. However, the minimally invasive method of transcatheter closure has always attracted the attention of cardiologists and patients. The present study aimed to apply transcatheter occlusion in treating ventricular septal defect with right coronary cusp bulge and further evaluate the clinical effect through follow-up. Materials and methods: A total of 40 children diagnosed as having a ventricular septal defect with right coronary cusp bulge, examined using transthoracic echocardiography and cardiovascular angiography, were enrolled in this study. The ventricular septal defects were closed by placing occluders through transcatheter occlusion treatment. During the operation process, the children underwent angiography and transthoracic echocardiography examinations to check the position of the occlude and the extent of aortic regurgitation. The influence of occlusion on the conduction system was evaluated using a surface electrocardiogram. The children were followed up after their procedures. Results: All 40 patients were immediately and successfully occluded. Three patients with filament residual shunts were observed during the operations. No major surgical complications occurred during the perioperative period. During the follow-up period, the positions of all the occluders were good, the residual shunts in the three patients disappeared, and no new or aggravated aortic regurgitation occurred. Electrocardiogram did not reveal any atrioventricular blocks. Only one patient suffered from an incomplete right bundle branch block. Conclusions: Children diagnosed with ventricular septal defect combined with right coronary cusp bulge could be considered for transcatheter occlusion. With appropriate indications and methods, the effect may be favorable. | Wei Ji Zhifang Zhang Wenchuo Zhao Jie Shen Lijun Fu Lin Shi Yiwei Chen Fen Li | 2018 | Journal of Interventional Medicine2018，1，4： | 3 |
