| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Roux-en-Y choledochojejunostomy using novel magnetic compressive anastomats in canine model of obstructive jaundice显示文摘BACKGROUND:The traditional hand-sewn Roux-en-Y choledochojejunostomy is technically complicated,and the incidence of postoperative complications has remained high.A set of novel magnetic compressive anastomats was introduced to facilitate choledochojejunostomy and improve the prognosis of patients.METHODS:After ligating the common bile duct for 7 days,16 dogs were randomly divided into two groups (n=8 per group).Anastomats were used in the study group,and the traditional hand-sewn method was used in the control group for standard Roux-en-Y choledochojejunostomy.We compared the operation time,incidence of complications,gross appearance,and pathological disparity in stoma between the two groups in 1-month and 3-month follow-up examinations.RESULTS:The time spent on constructing the anastomosis for the study group was significantly shortened.Although no anastomotic stenosis occurred in the two groups,the narrowing rate of biliary-enteric anastomosis was much higher in the control group.There was one case of bile leakage in the control group,whereas no bile leakage occurred in the study group.A smoother surface,an improved layer apposition,and a lower local inflammatory response were identified in the anastomosis of the study group.CONCLUSION:The structures of the novel magnetic compressive anastomats are simple,and they are time-saving,safe and efficient for performing Roux-en-Y choledocho- jejunostomy procedures in a canine model of obstructive jaundice. | Chao Fan,Xiao-Peng Yan,Shi-Qi Liu,Chun-Bao Wang,Jian-Hui Li,Liang Yu,Zheng Wu and Yi Lv Department of Hepatobiliary Surgery and Department of Pathology,First Affiliated Hospital,School of Medicine,Xi’an Jiaotong University,Xi’an 710061,China Department of Surgical Oncology,Third Affiliated Hospital,School of Medicine,Xi’an Jiaotong University,Xi’an 710068,China | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，1： | 49 |

| 5 | Soluble intercellular adhesion molecule-1,D-lactate and diamine oxidase in patients with inflammatory bowel disease显示文摘AIM:To study the levels of serum soluble intercellular adhesion molecule-1 (sICAM-1), plasma D-lactate and diamine oxidase (DAO) in patients with inflammatory bowel disease (IBD), and the potential clinical signif icance.METHODS: Sixty-nine patients with IBD and 30 healthy controls were included in this study. The concentration of sICAM-1 was detected with enzyme-linked immu-nosorbent assay, the level of D-lactate and DAO was measured by spectroscopic analysis, and the number of white blood cells (WBC) was determined by routine procedure.RESULTS:The levels of sICAM-l, DAO, and WBC in IBD patients were significantly higher than those in the control group (P<0.01). sICAM-l in IBD patients was found to be closely related to the levels of DAO and D-lactate (212.94±69.89 vs 6.35±2.35, P=0.000), DAO 212.94±69.89 vs 8.65±3.54, P=0.000) and WBC (212.94±69.89 vs 7.40±2.61, P=0.000), but no signif icant difference was observed between patients with ulcerative colitis and patients with Crohn's disease. The post-treatment levels of sICAM-l, D-lactate and WBC were significantly lower than before treatment (sICAM-l 206.57±79.21 vs 146.21±64.43, P=0.000), (D-lactate 1.46±0.94 vs 0.52±0.32, P=0.000) and (WBC 7.24±0.2.33 vs 5.21±3.21, P=0.000).CONCLUSION: sICAM-1, D-lactate and DAO are closely related to the specific conditions of IBD, and thus could be used as a major diagnostic index. | Wei-Bing Song Yong-Hui Lv Zhen-Shu Zhang Ya-Nan Li Li-Ping Xiao Xin-Pei Yu Yuan-Yuan Wang Hong-Li Ji Li Ma | 2009 | World Journal of Gastroenterology2009，15，31： | 23 |

| 8 | Sutureless Intestinal Anastomosis with a Novel Device of Magnetic Compression Anastomosis显示文摘Objective To explore the feasibility and efficiency of a novel magnetic compression anastomats(MCAs) in intestinal anastomosis.Methods A total of 36 male mongrel canines underwent intestinal anastomosis using traditional hand-sewn(n=18) or a novel MCAs(n=18).We compared the anastomosis time,postoperative complications,bursting strength of anastomoses,gross appearance,and pathology between two groups at each time-point of follow-up.Results The mean anastomosis time with MCAs was significantly less than that with hand-sewn(8.50±1.95 vs.31.1±4.32 minutes,P<0.001).The blood stools and intussusceptions occurred in both groups during follow-up period.Only 1 mongrel canine receiving intestinal anastomosis by MCAs experienced anastomotic leakage.The average bursting pressure of anastomoses obtained from mongrel canines undergoing intestinal anastomosis by MCAs was significantly higher than that by traditional hand-sewn at 1 week's follow-up time(P<0.05).Gross appearance of the anastomoses constructed by MCAs was relatively smoother and flatter.Pathological evalution of anastomoses revealed that general inflammation was greater in hand-sewn anastomoses than magnetic anastomosis.Conclusion The magnetic compression anastomat is a safe and effective device of sutureless intestinal anastomosis in canine models. | Chao Fan Jia Ma Hong-ke Zhang Rui Gao Jian-hui Li Liang Yu Zheng Wu Yi Lv | 2011 | Chinese Medical Sciences Journal2011，26，3： | 20 |
| 9 | Comparison of 5-hydroxytryptophan signaling pathway characteristics in diarrhea-predominant irritable bowel syndrome and ulcerative colitis显示文摘AIM: To study differences in the visceral sensitivity of the colonic mucosa between patients with diarrheapredominant irritable bowel syndrome(IBS-D) and those with ulcerative colitis(UC) in remission and to relate these differences with changes in the 5-hydroxytryptophan(5-HT) signaling pathway. METHODS: Gastrointestinal symptoms were used to determine the clinical symptom scores and rectal visceral sensitivity of patients with IBS-D and patients with UC in remission. Blood levels of 5-HT and5-hydroxyindoleacetic acid(5-HIAA) were measured using an HPLC-electrochemical detection system. The levels of 5-HT 3 receptor(3R), 4R, and 7R m RNAs in colonic biopsy samples were detected using reverse transcription-polymerase chain reaction. The protein expression of TPH1 was analyzed by Western blot and immunohistochemistry.RESULTS: Abdominal pain or discomfort, stool frequency, and the scores of these symptoms in combination with gastrointestinal symptoms were higher in the IBS-D and UC groups than in the control groups. However, no significant differences were observed between the IBS-D and UC remission groups. With respect to rectal visceral sensitivity, the UC remission and IBS-D groups showed a decrease in the initial perception threshold, defecating threshold and pain threshold. However, these groups exhibited significantly increased anorectal relaxation pressure. Tests examining the main indicators of the 5-HT signaling pathway showed that the plasma 5-HT levels, 5-HIAA concentrations, TPH1 expression in the colonic mucosa, and 5-HT3 R and 5-HT5 R expression were increased in both the IBS-D and the UC remission groups; no increases were observed with respect to 5-HT7 R expression.CONCLUSION: The IBS-D and UC groups showed similar clinical symptom scores, visceral sensitivity, and levels of serotonin signaling pathway indicators in the plasma and colonic mucosa. However, the pain threshold and 5-HT7 R expression in the colonic mucosa were significantly different between these groups. The results reveal that(1) IBS-D and UC are related to visceral sensitivity pathogenesis and the clinical manifestations of these conditions and(2) the observed differences in visceral hypersensitivity are possibly due to differences in levels of the 5-HT7 receptor, a component of the 5-HT signaling pathway. | Feng-Yan Yu Shao-Gang Huang Hai-Yan Zhang Hua Ye Hong-Gang Chi Ying Zou Ru-Xi Lv Xue-Bao Zheng | 2016 | World Journal of Gastroenterology2016，22，12： | 19 |
| 10 | Therapeutic efficacy of baclofen in refractory gastroesophageal reflux-induced chronic cough显示文摘AIM:To evaluate the efficacy and safety of baclofen for treatment of refractory gastroesophageal reflux-induced chronic cough (GERC) unresponsive to standard anti-reflux therapy. METHODS:Sixteen patients with refractory GERC were given an 8-wk course of baclofen 20 mg three times a day as an add-on therapy to omeprazole. Changes in the cough symptom score, cough threshold to capsaicin, reflux symptom score and possible adverse effects were determined after treatment. The variables of multi-channel intraluminal impedance combined with pH monitoring were compared between responders and non-responders to baclofen. RESULTS:Twelve of 16 patients completed treatment. Cough disappeared or improved in 56.3% (9/16)of patients, including 6 patients with acid refluxinduced cough (66.7%) and 3 patients with non-acid reflux-induced cough (33.3%). With baclofen treatment, the cough symptom score began to decrease at week 2, was clearly decreased at week 6 and reached a minimum at week 8. At the end of therapy, the lowest concentration of capsaicin required for induction of ≥ 2 and ≥ 5 coughs increased from 0.98 (1.46) to 1.95 (6.82) μmol/L (Z = -2.281, P = 0.024) and from 1.95 (7.31) to 7.8 (13.65) μmol/L (Z = -2.433, P = 0.014), respectively, and the reflux symptom score decreased from 8.0 ± 1.6 to 6.8 ± 0.8 (t = 2.454, P = 0.023). The number of acid reflux episodes was significantly lower in responders than in non-responders. The main adverse effects were somnolence, dizziness and fatigue. CONCLUSION:Baclofen is a useful, but suboptimal treatment option for refractory GERC. | Xiang-Huai Xu Zhong-Min Yang Qiang Chen Li Yu Si-Wei Liang Han-Jing Lv Zhong-Min Qiu | 2013 | World Journal of Gastroenterology2013，19，27： | 18 |
| 11 | Construction and Identification of a Human Liver Specific MicroRNA Eukaryotic Expression Vector显示文摘MiR-122 is one of the non-coding RNAs which showed its effects on the lipo-metablism,virus infection and HCC forming through regulation of liver gene expression.Its eukaryotic expression vector was constructed by using pSuper which was widely applied in the siRNA expression.The precursor of human miR-122 gene was amplified by polymerase chain reaction(PCR)from the human genomic DNA.The positive clones were screened by PCR and restriction enzyme digestion.The new expression vector of miR-122 was named pHsa-m122.PHsa-m122 and its controls were transfected to HepG2 cells.The miR-122 expression activity was evaluated by GFP122i sensor reporter plasmid through fluorescence detection and Western blot.It was shown that the fluorescence intensity of GFP122si and pHsa-m122 co-transfection group was weaker than that of the controls,so the functional activity of expressed miR-122 was detected.When HepG2 cells were co-transfected with HBV1.3 and pHsa-m122 plasmids, the results showed miR-122 may down-regulate the gene expression of HBV.The human liver specific microRNA eukaryotic expression vector of miR-122 was constructed successfully,which may facilitate further study of its function in the development of liver virus infection diseases and HCC. | Shanshan Chen Ming Ni Bing Yu Tingting Lv Mengji Lu Feili Gong | 2007 | Cellular & Molecular Immunology2007，4，6： | 18 |

| 13 | Effects of baicalin in CD4 + CD29 + T cell subsets of ulcerative colitis patients显示文摘AIM:To evaluate the role of baicalin in ulcerative colitis(UC) with regard to the CD4+CD29+ T helper cell,its surface markers and serum inflammatory cytokines.METHODS:Flow cytometry was used to detect the percentage of CD4+CD29+ cells in patients with UC.Real time polymerase chain reaction was used to detect expression of GATA-3,forkhead box P3,T-box expressed in T cells(T-bet),and retinoic acid-related orphan nuclear hormone receptor C(RORC).Western blotting was used to analyze expression of nuclear factor-κB(NF-κB) p65,phosphorylation of NF-κB(p-NF-κB) p65,STAT4,p-STAT4,STAT6 and p-STAT6.The concentrations of interferon-γ(IFN-γ),interleukin(IL)-4,IL-5,IL-6,IL-10 and TGF-β in serum were determined by ELISA assay.RESULTS:The percentages of CD4+CD29+ T cells were lower in treatment with 40 and 20 μmol/L baicalin than in the treatment of no baicalin.Treatment with 40 or 20 μmol/L baicalin significantly upregulated expression of IL-4,TGF-β1 and IL-10,increased p-STAT6/STAT6 ratio,but downregulated expression of IFN-γ,IL-5,IL-6,RORC,Foxp3 and T-bet,and decreased ratios of T-bet/GATA-3,p-STAT4/STAT4 and p-NF-κB/NF-κB compared to the treatment of no baicalin.CONCLUSION:The results indicate that baicalin regulates immune balance and relieves the ulcerative colitis-induced inflammation reaction by promoting proliferation of CD4+CD29+ cells and modulating immunosuppressive pathways. | Feng-Yan Yu Shao-Gang Huang Hai-Yan Zhang Hua Ye Hong-Gang Chi Ying Zou Ru-Xi Lv Xue-Bao Zheng | 2014 | World Journal of Gastroenterology2014，20，41： | 18 |
| 14 | Effect of ulinastatin combined rivaroxaban on deep vein thrombosis in major orthopedic surgery显示文摘Objective:To explore the effect of ulinastatin(UTI) continuous infusion combined Rivaroxaban on the deep vein thrombosis in patients undergoing major orthopedic surgery.Methods:Forty-five patients undergoing major orthopedic surgery were randomly divided into three groups:ulinastatin continuous infusion(Uc) group,ulinastatin single injection(Us) group and control(C) group.All patients received patient-controlled intravenous analgesia(PCIA) after operation,and took Rivaroxaban 10 mg orally 12 hours after operation.Ulinastatin(5 000 U/kg)was given intravenously to both Uc and Us groups preoperatively.Group C was given isometric normal saline,group Uc was pumped UTI continuous intravenously at the end of surgery(10 000U/kg) to 48 hours through PCIA pump.The values of hematocrit(HCT),thrombomodulin(TM),Interleukin(IL-6),thrombin-antithrombin complex(TAT),D-Dimer(D-D) were normally tested before surgery(T1),at the end of the surgery(T2),12 hours(T3).24 hours(T4) and 48 hours(T5)after surgery.Results:Compared with T1,there was an upward tendency in TM,IL-6,TAT,and D-D after operation in group C group(P <0.05).The values of them were significandy increased from nearly 24-hour after surgery in Us group(P<0.05).In group Uc.there were no significant changes in these indices after operation(P>0.05).Conclusions:During the perioperative period,ulinastatin continuous infusion combined Rivaroxaban can correct blood hypercoagulability through different approaches in patients undergoing major orthopedic surgery. | Xi Yu Yi Tian Ka Wang Ying-Lin Wang Guo-Yi Lv Guo-Gang Tian | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，11： | 17 |
| 15 | Preoperative assessment of hilar cholangiocarcinoma:combination of cholangiography and CT angiography显示文摘BACKGROUND:Hilar cholangiocarcinoma is one of the most difficult carcinomas to manage because of the location of the main tumor at the hepatic hilus and the complex anatomy of the biliary,arterial,and portal systems.To plan an operation,it is important to acquire accurate information about the relationship between hilar cholangiocarcinoma and adjacent vessels.This study aimed to evaluate the clinical value of cholangiography combined with spiral CT three-dimensional (3D)angiography for a preoperative assessment of hilar cholangiocarcinoma. METHODS:From March 2007 to August 2009,cholangiography was performed in 13 patients with hilar cholangiocarcinoma. Meanwhile,contrast-enhanced abdominal scanning was performed using 16-slice spiral CT,and the 3D images of the hepatic artery and portal vein were acquired.The level and range of invasion of the hepatic artery,the portal vein,and the bile duct,the preoperative Bismuth classification,and T-staging were recorded and compared with those after surgical exploration. RESULTS:The hepatic artery and portal vein were recon- structed successfully in all these patients.Percutaneous transhepatic cholangiography was performed in 9 patients,endoscopic retrograde cholangiopancreatography in 1,and magnetic resonance cholangiopancreatography in 3.The CT angiography records of invasion of the hepatic artery were consistent with the results of explorations in these patients. The data from 5 of the 13 patients were consistent with those on invasion of the portal vein.The results of the Bismuth classification and the T-staging system were consistent with those of surgical exploration in 12 of the 13 patients.Seven of 8 patients who were estimated to be suitable for operation based on images were curatively treated and 5 who were judged to be unsuitable for curative operation by cholangiography and CT angiography were confirmed intraoperatively and underwent palliative procedures. CONCLUSIONS:Cholangiography combined with multi-slice spiral 3D CT angiography can satisfactorily delineate the local invasion of hilar cholangiocarcinoma and accurately evaluate the resectability.This approach,therefore,contributes to the planning of safe operation. | Yu, Shi-An Zhang, Cheng Zhang, Jia-Min Mao, Gen-Jun Xu, Long-Tang Wu, Xiao-Kang Shu, Jin-Er Lv, Guang-Hong Zheng, Zhang-Dong | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，2： | 15 |
| 16 | Chromosomal level assembly and population sequencing of the Chinese tree shrew genome显示文摘Chinese tree shrews (Tupaia belangeri chinensis) have become an increasingly important experimental animal in biomedical research due to their close relationship to primates. An accurately sequenced and assembled genome is essential for understanding the genetic features and biology of this animal. In this study, we used long-read single-molecule sequencing and high-throughput chromosome conformation capture (Hi-C) technology to obtain a high-qualitychromosome-scale scaffolding of the Chinese tree shrew genome. The new reference genome (KIZ version 2: TS_2.0) resolved problems in presently available tree shrew genomes and enabled accurate identification of large and complex repeat regions, gene structures, and species-specific genomic structural variants. In addition, by sequencing the genomes of six Chinese tree shrew individuals, we produced a comprehensive map of 12.8 M single nucleotide polymorphisms and confirmed that the major histocompatibility complex (MHC) loci and immunoglobulin gene family exhibited high nucleotide diversity in the tree shrew genome. We updated the tree shrew genome database (TreeshrewDB v2.0: http://gffzzb70c77447da74c53h5wuuc96ff6xc6wkk.ffgz.tsg.suse.edu.cn) to include the genome annotation information and genetic variations. The new high-quality reference genome of the Chinese tree shrew and the updated TreeshrewDB will facilitate the use of this animal in many different fields of research. | Yu Fan Mao-Sen Ye Jin-Yan Zhang Ling Xu Dan-Dan Yu Tian-Le Gu Yu-Lin Yao Jia-Qi Chen Long-Bao Lv Ping Zheng Dong-Dong Wu Guo-Jie Zhang Yong-Gang Yao | 2019 | Zoological Research2019，40，6： | 15 |

| 18 | The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production. | Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao | 2020 | Molecular Plant2020，13，2： | 15 |
| 19 | Chinese progress in geomorphometry显示文摘Geomorphometry,the science of digital terrain analysis(DTA),is an important focus of research in both geomorphology and geographical information science(GIS).Given that 70% of China is mountainous,geomorphological research is popular among Chinese scholars,and the development of GIS over the last 30 years has led to significant advances in geomorphometric research.In this paper,we review Chinese progress in geomorphometry based on the published literature.There are three major areas of progress:digital terrain modelling methods,DTA methods,and applications of digital terrain models(DTMs).First,traditional vector-and raster-based terrain modelling methods,including the assessment of uncertainty,have received widespread attention.New terrain modelling methods such as unified raster and vector,high-fidelity,and real-time dynamic geographical scene modelling have also attracted research attention and are now a major focus of digital terrain modelling research.Second,in addition to the popular DTA methods based on topographical derivatives,geomorphological features,and hydrological factors extracted from DTMs,DTA methods have been extended to include analyses of the structure of underlying strata,ocean surface features and even socioeconomic spatial structures.Third,DTMs have been applied to fields including global climate change,analysis of various typical regions,lunar surface and other related fields.Clearly,Chinese scholars have made significant progress in geomorphometry.Chinese scholars have had the greatest international impact in areas including high-fidelity digital terrain modelling and DTM-based regional geomorphological analysis,particularly in the Loess Plateau and the Tibetan Plateau regions. | LV Guonian XIONG Liyang CHEN Min TANG Guoan SHENG Yehua LIU Xuejun SONG Zhiyao LU Yuqi YU Zhaoyuan ZHANG Ka WANG Meizhen | 2017 | Journal of Geographical Sciences2017，27，11： | 14 |
| 20 | Roux-en-Y gastric bypass promotes expression of PDX-1 and regeneration of β-cells in Goto-Kakizaki rats显示文摘AIM:To study the effects of Roux-en-Y gastric bypass(RYGB) on the expression of pancreatic duodenal homeobox-1(PDX-1) and pancreatic β-cell regeneration/neogenesis,and their possible mechanisms in diabetics.METHODS:Three groups of randomly selected nonobese diabetic Goto-Kakizaki(GK) rats were subjected to RYGB,sham-RYGB and sham-operation(sham-op) surgery,respectively.The rats were euthanized at postoperative 1,2,4 and 12 wk.Their pancreases were resected and analyzed using reverse transcription polymerase chain reaction to detect the mRNA of PDX-1.Anti-PDX-1 immunohistochemical(IHC) staining and Western blotting were used to detect the protein of PDX-1.Double IHC staining of anti-Brdu and-insulin was performed to detect regenerated β-cells.The index of double Brdu and insulin positive cells was calculated.RESULTS:In comparison with sham-RYGB and sham-op groups,a significant increase in the expressions of PDX-1 mRNA in RYGB group was observed at all experimental time points(1 wk:0.378 ± 0.013 vs 0.120 ± 0.010,0.100 ± 0.010,F = 727.717,P < 0.001;2 wk:0.318 ± 0.013 vs 0.110 ± 0.010,0.143 ± 0.015,F = 301.509,P < 0.001;4 wk:0.172 ± 0.011 vs 0.107 ± 0.012,0.090 ± 0.010,F = 64.297,P < 0.001;12 wk:0.140 ± 0.007 vs 0.120 ± 0.010,0.097 ± 0.015,F = 16.392,P < 0.001);PDX-1 protein in RYGB group was also increased significantly(1 wk:0.61 ± 0.01 vs 0.21 ± 0.01,0.15 ± 0.01,F = 3031.127,P < 0.001;2 wk:0.55 ± 0.00 vs 0.15 ± 0.01,0.17 ± 0.01,F = 3426.455,P < 0.001;4 wk:0.39 ± 0.01 vs 0.18 ± 0.01,0.22 ± 0.01,F = 882.909,P < 0.001;12 wk:0.41 ± 0.01 vs 0.20 ± 0.01,0.18 ± 0.01,F = 515.833,P < 0.001).PDX-1 mRNA and PDX-1 protein production showed no statistical significance between the two sham groups.Many PDX-1 positive cells could be found in the pancreatic islets of the rats in RYGB group at all time points.In addition,the percentage of Brdu-insulin double staining positive cells was higher in RYGB group than in the other two groups(1 wk:0.22 ± 0.13 vs 0.03 ± 0.06,0.03 ± 0.06,P < 0.05;2 wk:0.28 ± 0.08 vs 0.00 ± 0.00,0.03 ± 0.06,P < 0.05;4 wk:0.24 ± 0.11 vs 0.07 ± 0.06,0.00 ± 0.00,P < 0.001;12 wk:0.20 ± 0.07 vs 0.03 ± 0.06,0.00 ± 0.00,P < 0.05).CONCLUSION:RYGB can increase the expression of pancreatic PDX-1 and induce the regeneration of β-cells in GK rats.The associated regeneration of islet cells may be a possible mechanism that how RYGB could improve type 2 diabetes mellitus. | Zhen Li,Dong-Fei Li,Jing-Xing Dai,Yu Bai,Lin Yuan,Southern Medical University,Institute of Basic Medical Anatomy National Key Disciplines,Guangzhou 510515,Guangdong Province,China Hong-Ya Zhang,Lu-Xian Lv,Wen-Qiang Li,Second Affiliated Hospital,Xinxiang Medical College,Henan Province Key Laboratory of Biological Psychiatry,Xinxiang 453002,Henan Province,China Ou Sha,Department of Anatomy,Faculty of Medicine,Shenzhen University,Shenzhen 518060,Guangdong Province,China | 2010 | World Journal of Gastroenterology2010，16，18： | 14 |
