1Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang 2020Chinese Medical Journal2020,,9:99
2Long-term follow-up of the effects of fecal microbiota transplantation in combination with soluble dietary fiber as a therapeutic regimen in slow transit constipation显示文摘As some studies have reported that strategies targeting the gut microbiota such as fecal microbiota transplantation(FMT) with or without other microecological therapy might have efficacy in treating slow transit constipation(STC), we conducted a singlecenter, open-label trial to study the long-term effect of FMT combined with soluble dietary fiber(pectin) on STC. Thirty-one adult patients with STC were enrolled into the trial. Patients received 6-day FMT procedures repeatedly for the first 3 months and soluble dietary fiber(pectin) daily during the follow-up. The rate of clinical remission and improvement, stool consistency, the Wexner constipation scale, and assessment of constipation-related symptoms were evaluated at week 4 and 1 year later. The clinical remission and improvement rates at week 4 were 69.0%(20/29) and 75.9%(22/29), respectively. At the end of the study,48.3%(14/29) of patients continued to have at least three complete spontaneous bowel movements per week and 58.6%(17/29)of patients showed clinical improvements. Stool consistency, the Wexner constipation scale, and constipation symptoms improved both at short-term and long-term follow-up. The results indicated that FMT in combination with soluble dietary fiber(pectin) had both short-term and long-term efficacy in treating STC.Xueying Zhang Hongliang Tian Lili Gu Yongzhan Nie Chao Ding Xiaolong Ge Bo Yang Jianfeng Gong Ning Li 2018Science China(Life Sciences)2018,61,7:33

4Management of cytokine release syndrome related to CAR-T cell therapy显示文摘Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer.Hongli Chen Fangxia Wang Pengyu Zhang Yilin Zhang Yinxia Chen Xiaohu Fan Xingmei Cao Jie Liu Yun Yang Baiyan Wang Bo Lei Liufang Gu Ju Bai Lili Wei Ruili Zhang Qiuchuan Zhuang Wanggang Zhang Wanhong Zhao Aili He 2019Frontiers of Medicine2019,13,5:21

6A Pilot Study of the Therapeutic Efficacy and Mechanism of Artesunate in the MRL/lpr Murine Model of Systemic Lupus Erythematosus显示文摘Recent evidence indicates that artesunate has immunomodulatory properties that might be useful for treating autoimmune disease.In this study,we conducted a pilot study and explored the effect and mechanism of artesunate on the treatment of systemic lupus erythematosus using an MRL/lpr murine model.MRL/lpr mice were divided into control,cyclophosphamide(CTX)and artesunate treatment groups.Blood was collected to measure serum levels of creatinine,antinuclear antibody(ANA)and anti-double-stranded DNA(anti-dsDNA)antibody.Twenty-four-hour urine was collected to measure levels of proteinuria.The concentration of monocyte chemotactic protein-1(MCP-1)in serum and urine was measured.The expression of MCP-1 in kidney was detected by Western blot and immunohistochemistry assay,respectively.The expression of B cell activating factor(BAFF)in spleen was determined by real time-PCR and immunoblotting.We found that artesunate significantly increased the survival rate,body weight and blood leukocyte counts,and reduced the serum levels of ANA and anti-dsDNA antibody titer,24 h urinary protein,and serum creatinine.Our results indicated that artesunate could decrease MCP-1,major pro-inflammation cytokine,in serum,urine and kidney.We also found that the level of BAFF,the major B cell activation factor,was decreased in artesunate treated MRL/lpr mice.Its efficacy was comparable with that of CTX in this study.Taken together,we have demonstrated that artesunate can inhibit the progression of disease and reverse the pathologic lesion of lupus nephritis.Ouyang Jin Huayong Zhang Zhifeng Gu Shengnan Zhao Ting Xu Kangxing Zhou Bo Jiang Jie Wang Xiaofeng Zeng Lingyun Sun 2009Cellular & Molecular Immunology2009,6,6:20
7Outcomes and possible risk factors associated with axis alignment and rotational stability after implantation of the Toric implantable collamer lens for high myopic astigmatism显示文摘·AIM:To assess the visual outcomes and possible risk factors associated with axis alignment and rotational stability after implantation of Toric implantable collamer lens (TICL) for the correction of high myopic astigmatism. ·METHODS:In this prospective, nonrandomized clinical study, 54 consecutive eyes of 29 patients with high myopic astigmatism received TICL implantation. To evaluate postoperative axis deviation from the intended axis, a digital anterior segment photograph was taken. The ultrasound biomicroscopy(UBM) was used to observe footplate-position. ·RESULTS:After mean follow-up of 8.6 months, mean manifest refractive cylinder (MRC) decreased 79.3% from (-1.88±1.49)D preoperatively to (0.39±0.61)D postoperatively. MRC within 1.00D occurred in 68.5% (37/54) of eyes, whereas 48.1% (26/54) had MRC within 0.50D. Mean manifest refraction spherical equivalent (MRSE) changed from (-12.08±4.22)D preoperatively to (-0.41±0.61)D postoperatively. Uncorrected binocular vision of 20/20 or better occurred in 72.2%(39/54) of patients compared with binocular best-corrected visual acuity (BCVA) of 20/20 or better in 44.4% (24/54) preoperatively. The mean difference between intended and achieved TICL axes was (6.96±8.37)°. Footplates of TICLs were in the ciliary sulcus in 22 eyes (46.3%), below the ciliary sulcus in 32 eyes (53.7%). The angle of TICL rotation had significant correlation with the footplates-position (t =2.127; P =0.045) and the postoperative TICL vaulting (r =-0.516; P =0.000). ·CONCLUSION:The results of our study further support the safety, efficacy and predictability of TICL for the correct high myopic astigmatism. The footplate-position of TICL and vault value should be taken into consideration as two possible risks factors for TICL rotation.Xun-Lun Sheng, De-Jun Zhu 2012International Journal of Ophthalmology(English edition)2012,5,4:19
8Abnormality diagnosis of cracks in the concrete dam based on dynamical structure mutation显示文摘A method of the fuzzy cross-correlation factor exponent in dynamics is researched and proposed to diagnose abnormality of cracks in the concrete dam. Moreover, the Logistic time series changing from period-doubling bifurcation to chaos is tested first using this method. Results indicate that it can distinguish inherent dynamics of time series and can detect mutations. Considering that cracks in the concrete dam constitute an open, dissipative and complex nonlinear dynamical system, a typical crack on the downstream face of a concrete gravity arch dam is analyzed with the proposed method. Two distinct mutations are discovered to indicate that the abnormality diagnosis of cracks in the concrete dam is achieved dynamically through this method. Furthermore, because it can be directly utilized in the measured crack opening displacement series to complete abnormality diagnosis, it has a good prospect for practical applications.GU ChongShi LI ZhanChao XU Bo 2011Science China(Technological Sciences)2011,54,7:18
9Immediate Effects of Hegu Needling on Adhesive Scapulohumeral Periarthritis显示文摘Objective:To observe the immediate effects of Hegu needling at Ashi points in patients with adhesive scapulohumeral periarthritis (SP). Methods:A total of 60 SP cases were randomized into a treatment group and a control group, 30 in each group. Cases in the treatment group were treated with Hegu needling at Ashi points and normal needling at other local points. Cases in the control group were treated with normal needling at local points alone. The therapeutic efficacy was then evaluated and analyzed using short-form of McGill pain questionnaire (SF-MPQ) and Japanese Orthopaedic Association (JOA) shoulder scoring system. Results:Hegu needling at Ashi points can substantially alleviate pain in patients with adhesive SP, showing a statistically significant difference when compared with the control group (P<0.01 or P<0.05). In addition, cases in the treatment group obtained better effects in abductor muscle strength, endurance, arm raising, internal rotation, external rotation, activities of daily living (ADL) and joint stability than those in the control group (P<0.01 or P<0.05). Conclusion:Hegu needling at Ashi points is effective for adhesive SP.Fan Xiao-peng Cheng Bo Huang Yin Gu Kan Zong Lei Han Chou-ping 2013Journal of Acupuncture and Tuina Science2013,11,4:17
10Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C.Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang 2019Research in Astronomy and Astrophysics2019,19,11:17
11Effect of Nb on Mechanical Properties of HAZ for High-Nb X80 Pipeline Steels显示文摘The mechanical properties of heat affected zone(HAZ)of two commercial high-Nb X80grade pipeline steels with different alloy elements were investigated using thermal simulation performed on a Gleeble-3500thermal simulator.The results showed that the high-Nb steels have excellent weldability.Embrittlement regions appear in coarse grain heat affected zone(CGHAZ)and intercritically heat affected zone(ICHAZ);Softening region appears in fine-grain heat affected zone(FGHAZ),and the strength here was even lower than 555 MPa as required in the standard.Meanwhile,with the increase of heat input,the strength and the toughness of HAZ of steel with high Nb,C and lower alloy decrease notably.Therefore,take into account the welding procedure during manufacture of weld pipe,suitable amount of alloy elements,such as Cr,Ni,Cu,Mo and so on,is necessary for high Nb X80heavythick steel plate.CHEN Xiao-wei LIAO Bo QIAO Gui-ying GU Yu WANG Xu XIAO Fu-ren 2013Journal of Iron and Steel Research(International)2013,20,12:15
12Comprehensive eco-environmental effects of the shelter-forest ecological engineering along the Tarim Desert Highway显示文摘In this work, we report a comprehensive study about the eco-environmental effects of the shelter forest along the Tarim Desert Highway, including the effects on aeolian environment, soil, micro-climate, biodiversity, and groundwater. The results show that: (1) The movement of windblown sand near the ground surface was affected by the shelter forest. The wind speed and sediment transport rate in the shelter forest decreased by 64%―80% and 87.45%―99.02%, respectively. In addition, there were also significant changes in the sand flux structure, the sand grain size, and the deflation and deposition on the ground surface. (2) Compared to the natural mobile sand, the soil bulk density in the forest area decreased while the total salt content, the total porosity, and the water content increased. In addition, the soil fertility was significantly improved in the forest area, and showed the 'first rapid, then slow' variation pattern. (3) The shelter forest showed positive effects on the micro-climate. Within the 6 m height above the ground, the air temperature in the shelter forest at different heights was lower than that in the mobile sand, while the air humidity was higher, while, the soil temperature was also lower in the shelter forest than mobile sand. (4) The number of soil microbial species increased significantly with the improvement of habitat in the shelterbelt. However, the population of different species was not distributed evenly across the surveyed area. (5) Currently, no significant effects of groundwater-pumping and forest-irrigation water have been found on the groundwater level and its salinity. The variation amplitude of both groundwater level and salinity was at the level of centimeters and 1g/L, respectively. No obvious variation trend has been observed.LEI JiaQiang LI ShengYu JIN ZhengZhong FAN JingLong WANG HaiFeng FAN DongDong ZHOU HongWei GU Feng QIU YongZhi XU Bo 2008Chinese Science Bulletin2008,53,S2:14
13A novel compound AB38b attenuates oxidative stress and ECM protein accumulation in kidneys of diabetic mice through modulation of Keap1/Nrf2 signaling显示文摘Extracellular matrix(ECM)deposition following reactive oxygen species(ROS)overproduction has a key role in diabetic nephropathy(DN),thus,antioxidant therapy is considered as a promising strategy for treating DN.Here,we investigated the therapeutic effects of AB38b,a novel syntheticα,β-unsaturated ketone compound,on the oxidative stress(OS)and ECM accumulation in type 2 diabetes mice,and tried to clarify the mechanisms underlying the effects in high glucose(HG,30 mM)-treated mouse glomerular mesangial cells(GMCs).Type 2 diabetes model was established in mice with high-fat diet feeding combined with streptozocin intraperitoneal administration.The diabetic mice were then treated with AB38b(10,20,40 mg·kg^?1·d^?1,ig)or a positive control drug resveratrol(40 mg·kg^?1·d^?1,ig)for 8 weeks.We showed that administration of AB38b or resveratrol prevented the increases in malondialdehyde level,lactate dehydrogenase release,and laminin and type IV collagen deposition in the diabetic kidney.Simultaneously,AB38b or resveratrol markedly lowered the level of Keap1,accompanied by evident activation of Nrf2 signaling in the diabetic kidney.The underlying mechanisms of antioxidant effect of AB38b were explored in HG-treated mouse GMCs.AB38b(2.5?10μM)or resveratrol(10μM)significantly alleviated OS and ECM accumulation in HG-treated GMCs.Furthermore,AB38b or resveratrol treatment effectively activated Nrf2 signaling by inhibiting Keap1 expression without affecting the interaction between Keap1 and Nrf2.Besides,AB38b treatment effectively suppressed the ubiquitination of Nrf2.Taken together,this study demonstrates that AB38b ameliorates experimental DN through antioxidation and modulation of Keap1/Nrf2 signaling pathway.Lei Du Lei Wang Bo Wang Jin Wang Meng Hao Yi-bing Chen Xi-zhi Li Yuan Li Yan-fei Jiang Cheng-cheng Li Hao Yang Xiao-ke Gu Xiao-xing Yin Qian Lu 2020Acta Pharmacologica Sinica2020,41,3:13

15Production of a newly isolated Paenibacillus polymyxa biocontrol agent using monosodium glutamate wastewater and potato wastewater显示文摘A phyllosphere bacterial strain EBL-06 was isolated from wheat leaves. The morphology, cultural characteristics, phospholipid fatty acids, physiological and antagonistic fungus activities of this strain were investigated. A phylogenetic tree was constructed by comparing with the published 16S rDNA sequences of the relevant bacteria. The results showed that the isolate EBL-06 was a strain of Paenibacillus polymyxa; this strain performed a high level of antagonistic fungus activity toward a broad spectrum of phytopathogens, such as Botrytis cinerea, Cladosporium cucumerinum, Fusarium spp. The isolate EBL-06 can grow well using monosodium glutamate wastewater (MGW) and potato wastewater (PW) as culture medium. The maximum yield of 6.5 × 10 9 CFU/mL of the isolate EBL-06 anti-fungus biocontrol agent was reached in 15 hr cultivation at 28°C, pH 6.0–7.5 using the mixture of MGW and PW (1:9).Likun Gu Zhihui Bai Bo Jin Jianyun Zhang Wenying Li Guoqiang Zhuang Hongxun Zhang 2010Journal of Environmental Sciences2010,22,9:12
16Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12

19Classification and regionalization of the forming environment of windblown sand disasters along the Tarim Desert Highway显示文摘Through the systematic field survey and observations, the factor quantification as well as setting the criteria, the sand disaster-forming environment along the Tarim Desert Highway can be divided into four grades by the classification and regionalization based on fuzzy mathematics. The length of the regions with significant sand disaster accounted for 37.1% of the total highway length. Particularly, the area along the Tarim Desert Highway, based on the sand disaster-forming environment classification as well as the difference in the five basic landform units along the highway, combined with the difference of wind regime, can be divided into five regions, in which the length of the regions suffering severe sand damage occupied 64.3% of the total highway length. In addition, the index of disaster formation grade along the highway decreased from north to south, showing a repeated spatial pattern in small length scales.LEI JiaQiang LI ShengYu FAN DongDong ZHOU HongWei GU Feng QIU YongZhi XU Bo LIU Shang DU WenYi YAN ZengHui WANG YongChang 2008Chinese Science Bulletin2008,53,S2:11
20Double-balloon enteroscopy for mesenchymal tumors of small bowel:Nine years' experience显示文摘AIM:To assess the value of double-balloon enteroscopy(DBE) for the diagnosis of gastrointestinal mesenchymal tumors(GIMTs) in the small bowel and clarify their clinical and endoscopic characteristics.METHODS:A retrospective review in a total of 783 patients who underwent a DBE procedure from January 2003 to December 2011 was conducted.Data from patients with pathologically confirmed GIMTs were analyzed at a single tertiary center with nine years' experience.The primary outcomes assessed included characteristics of patients with GIMTs,indications for DBE,overall diagnostic yield of GIMTs,endoscopic morphology,positive biopsy,comparison of diagnosis with capsule endoscopy,and subsequent interventional management.RESULTS:GIMTs were identified and analyzed in 77 patients.The mean age was 47.74 ± 14.14 years(range:20-77 years),with 63.6% being males.The majority of individuals presented with gastrointestinal bleeding,accounting for 81.8%,followed by abdominal pain,accounting for 10.4%.Small bowel pathologies were found in 71 patients,the detection rate was 92.2%.The diagnostic yield of DBE for GIMTs was 88.3%.DBE was superior to capsule endoscopy in the diagnosis of GIMTs(P = 0.006;McNemar's χ2 test).Gastrointestinal stromal tumor was the most frequent and leiomyoma was the second frequent GIMT.Single and focal lesions were typical of GIMTs,and masses with smooth or unsmooth surface were the most common in the small bowel.GIMTs were removed from all the patients surgically except one patient treated with endoscopic resection.CONCLUSION:DBE is a safe and valuable procedure for patients with suspected GIMTs,and it provides an accurate position for subsequent surgical intervention.Qiong He Yang Bai Fa-Chao Zhi Wei Gong Hong-Xiang Gu Zhi-Min Xu Jian-Qun Cai De-Shou Pan Bo Jiang 2013World Journal of Gastroenterology2013,19,11:11
