| 1 | Downregulation of electroacupuncture at ST36 on TNF-α in rats with ulcerative colitis显示文摘AIM: To investigate the regulatory effect of electroacupuncture (EA) at Zusanli (ST36) on tumor necrosis factor-alpha (TNFα) in rats with ulcerative colitis (UC), and further elucidate the therapeutic mechanism of EA on UC.METHODS: Thirty-two male Sprague-Dawley (SD) rats were randomly divided into four groups (n=-8): normal control group, UC control group, UC+ST36 group and UC+nonacupoint group. A solution containing ethanol and 2,4,6-trinitrobenzenesulfonic acid (TNBS) was instilled into the distal colon in the rat (at a dose of 100 mg/kg) to set up UC rat model. Rats in wakefulness state of UC+ST36 group were stimulated at ST36 by EA once a day, while those of UC+nonacupoint group were done at 0.5 cm beside ST36. After 10d treatment, all rats were sacrificed simultaneously. Colon musocal inflammation and damage were assessed by measuring colon mass, morphologic damage score, colonic myeloperoxidase enzyme (MPO) activity, serum TNF-α and colonic TNF-α mRNA level. Morphologic damage score was examined under stereomicroscope. Colonic MPO activity was measured by spectrophotometer method. Serum TNF-αconcentration was determined by radioimmunoassay (RIA).Colonic TNF-α mRNA expression level was analyzed by semiquantitative reverse transcription polymerase chain reaction (RT-PCR).RESULTS: Ratio of colonic mass/body mass (mC/mB) and activity of colonic MPO (μkat/g tissue) markedly increased (8.5±2.6 vs 2.5±0.4; 145±25 vs 24±8, P<0.01 vs normal control group). Compared with normal control rats, serum TNF-α and colonic TNF-α mRNA level in UC control group were increased 2.5 fold (2 278±170 vs 894±248, P<0.01)and 4.3 fold (0.98±0.11 vs 0.23±0.11, P<0.01)respectively. After EA at ST36, mc/mB and MPO activity were reduced significantly (5.3±2.0 vs 8.5±2.6; 104±36 vs145±25, P<0.01, 0.05) compared with those of UC control group. Serum TNF-α and colonic TNF-α mRNA level were inhibited by EA stimulation at ST36 (P<0.01). The inhibitory rate was 16 % and 44 % respectively.Morphologic damage score was also increased markedly in rat with UC (P<0.01), whereas it was decreased by EA at ST36 (P<0.05). There was no significant difference between UC control group and UC+EA at non-acupoint (P>0.05). Furthermore, these parameters were highly correlated with each other (P<0.01).CONCLUSION: Serum TNF-α concentration and colonic TNF-α mRNA expression level are increased significantly in UC rats in correlation with the severity of disease. It indicates that TNF-α is closely involved in the immune abnormalities and inflammatory responses in UC. EA at ST36 has therapeutic effect on UC by downregulating serum TNF-r and colonic TNF-r mRNA expression. High levels of TNF-αand its corresponding mRNA expression seem to be implicated in the pathogenesis of UC. | LiTian Yu-XinHuang MinTian WeiGao QingChang | 2003 | World Journal of Gastroenterology2003，9，5： | 25 |
| 2 | Antiangiogenic effect of somatostatin receptor subtype 2 on pancreatic cancer cell line:Inhibition of vascular endothelial growth factor and matrix metalloproteinase-2 expression in vitro显示文摘AIM:To investigate the anti-angiogenic effect of somatostatin receptor subtype 2 (SSTR2) gene transfer into pancreatic cancer cell line PC-3, and the mechanisms involved in this effect.METHODS: The full length human SSTR2 cDNA was introduced into pancreatic cancer cell line PC-3 by lipofectamine-mediated transfection. Positive clones were screened by G418 and stable expression of SSTR2 was detected by immunohistochemistry SABC methods and RT-PCR. Enzyme-linked immunosorbent assay (ELISA) was used to detect vascular endothelial growth factor (VEGF) levels in the cell culture supernatants of SSTR2-expressing cells, vector control and mock control cells. Furthermore, the expressions of VEGF and matrix metalloproteinase-2 (MMP-2) were detected by immunohistochemistry SABC methods and RT-PCR in these cells.RESULTS: VEGF levels in the cell culture supernatants were significantly reduced in the SSTR2-expressing cells (first week,172.63±21.2ng/L and after two months, 198.85±26.44ng/L)compared with the vector control (first week, 790.39±86.52ng/L and after two months, 795.69±72.35ng/L) and mock control (first week, 786.42±90.62ng/L and after two months,805.32±84.36ng/L) (P<0.05).The immunohistochemical assay showed a significant reduction of the integral optical density of VEGF and MMP-2 in the SSTR2-expressing cells (42.25±8.6 and 70.5±6.25, respectively) compared with the vector control (85.75±12.9 and 110.52±13.5, respectively) and mock control (82.6±9.28 and 113.56±9.62,respectively) (P<0.05).Conversely, the average gray value of VEGF and MMP-2 was significantly increased in the SSTR2-expressing cells (121.56±8.43 and 134.46±19.95, respectively) compared with the vector control (55.72±5.6 and 62.26±12.68,respectively) and mock control cells (58.48±6.2 and 65.49±9.16, respectively) (P<0.05). Moreover, the expressions of VEGF mRNA and MMP-2 mRNA were significantly reduced in the SSTR2-expressing cells (0.1384±0.017 and 0.2343±0.070, respectively) compared with the vector control (1.024±0.117 and 0.806±0.119,respectively) and mock control (1.085±0.105 and 0.714±0.079,respectively) (P<0.05).CONCLUSION: The expression of reintroduced human SSTR2 gene exerts its antiangiogenic effects by downregulating the expressions of the factors involved in tumor angiogenesis and metastasis, suggesting SSTR2 gene transfer as a new strategy of gene therapy for pancreatic cancer. | ManojKumar Zheng-RenLiu LaxmiThapa QingChang Da-YuWang Ren-YiQin | 2004 | World Journal of Gastroenterology2004，10，3： | 23 |
| 3 | Subaquatic volcanic eruptions in continental facies and their influence on high quality source rocks shown by the volcanic rocks of a faulted depression in Northeast China显示文摘This paper reports the analysis on cores and rock slices,data on seismic and logging activities,characteristics of core samples,and the paleogeographic background of the Yingcheng Formation of the Xujiaweizi faulted depression in the Songliao Basin.The results show that some of the volcanic rocks were formed during subaquatic eruptions.These subaqueous volcanic rocks are further characterized by the interbedded black mudstone and tuffite,the presence of double-layer perlite enclosing aphyric or sparsely phyric rhyolite,the presence of a bentonite layer,and the coefficient of oxidation(Fe2O3/FeO).The types of rocks are volcanic breccia,lava breccias,perlite,rhyolite,tuff and sedimentary tuff.The subaquatic eruptions are distributed mainly in Wangjiatun,Shengping,Xuxi,Xuzhong,and Xudong.The XS-1 area is the most typical.The organic abundance of overburden mud rocks within the volcanic rocks of the Yingcheng Formation indicates that these rocks represent high-quality source rocks.The analysis also shows that continental subaquatic volcanic eruptions provide a rich supply of minerals and energies for the lake basin and increase the organic matter content in the water.Moreover,the water differentiation provides a good reducing environment for the conservation of organic matter,and is beneficial for the formation of high-quality source rocks.Finally,we propose a hypothesis to describe the mode of subaquatic eruptions and the formation of high-quality source rocks. | SHAN XuanLong LI JiYan CHEN ShuMin RAN QingChang CHEN GuiBiao LIU Chao | 2013 | Science China Earth Sciences2013，56，11： | 6 |
| 4 | A Comparative Study on Hydrodynamic Performance of Double Deflector Rectangular Cambered Otter Board显示文摘In the present work,the hydrodynamic performance of the double deflector rectangular cambered otter board was studied using wind tunnel experiment,flume tank experiment and numerical simulation.Results showed that the otter board had a good hydrodynamic performance with the maximum lift-to-drag ratio(K_(MAX) = 3.70).The flow separation occurred when the angle of attack(AOA) was at 45?,which revealed that the double deflector structure of the otter board can delay the flow separation.Numerical simulation results showed a good agreement with experiment ones,and could predict the critical AOA,which showed that it can be used to study the hydrodynamic performance of the otter board with the advantage of flow visualization.However,the drag coefficient in flume tank was much higher than that in wind tunnel,which resulted in a lower lift-to-drag ratio.These may be due to different fluid media between flume tank and wind tunnel,which result in the big difference of the vortexes around the otter board.Given the otter boards are operated in water,it was suggested to apply both flume tank experiment and numerical simulation to study the hydrodynamic performance of otter board. | XU Qingchang FENG Chunlei HUANG Liuyi XU Jiqiang WANG Lei ZHANG Xun LIANG Zhenlin TANG Yanli ZHAO Fenfang WANG Xinxin | 2018 | Journal of Ocean University of China2018，17，5： | 5 |
| 5 | A novel aldo-keto reductase gene, IbAKR, from sweet potato confers higher tolerance to cadmium stress in tobacco显示文摘High concentrations of Cd can inhibit growth and reduce the activity of the photosynthetic apparatus in plants. In several plant species, aldo-keto reductases(AKRs) have been shown to enhance tolerance to various abiotic stresses by scavenging cytotoxic aldehydes;however, few AKRs have been reported to enhance Cd stress tolerance. In this study, the gene Ib AKR was isolated from sweet potato. The relative expression levels of Ib AKR increased significantly(approximately 3-fold) after exposure to 200 mmol$L–1 Cd Cl2 or 10 mmol$L–1 H2 O2. A subcellular localization assay showed that Ib AKR is predominantly located in the nucleus and cytoplasm.Ib AKR-overexpressing tobacco plants showed higher tolerance to Cd stress than wild-type(WT). Transgenic lines showed a significant ability to scavenge malondialdehyde(MDA) and methylglyoxal(MG). In addition,proline content and superoxide dismutase activity were significantly higher and H2 O2 levels were significantly lower in the transgenic plants than in the WT. Quantitative real-time PCR analysis showed that the reactive oxygen species(ROS) scavenging genes encoding guaiacol peroxidase(GPX), ascorbate peroxidase(APX), monodehydroascorbate reductase(MDHAR) and peroxidase(POD) were significantly upregulated in transgenic plants compared to WT under Cd stress. These findings suggest that overexpressing Ib AKR enhances tolerance to Cd stress via the scavenging of cytotoxic aldehydes and the activation of the ROS scavenging system. | Jinxi HUO Bing DU Sifan SUN Shaozhen HE Ning ZHAO Qingchang LIU Hong ZHAI | 2018 | Frontiers of Agricultural Science and Engineering2018，5，2： | 4 |
| 6 | Potential inhibition of cytochrome P450 3A4 by propofol in human primary hepatocytes显示文摘AIM: Hepatic cytochrome P450 isoenzymes constitute a superfamily of hemoproteins that play a major role in the metabolism of endogenous compounds and in the detoxification of xenobiotic molecules. P450 3A4 is one of the most important forms in human being, and mediates the metabolism of around 70% of therapeutic drugs and endogenous compounds. Propofol, a widely used intravenous anesthetic drug, is known to inhibit cytochrome P450activities in isolated rat hepatocytes. The goal of this study was to evaluate the potential efficacy of propofol on P4503A4 in a dose-dependent manner to understand its drugdrug interaction.METHODS: Hepatocytes were isolated from liver specimens from hepatic angioma patients undergone hepatic surgery.Primary incubated hepatocytes were treated with 0, 0.01,0.05, 0.1, 0.5, and 1.0 mM propofol for 24 hours. P450 3A4activity was measured with Nash′s colorimetry. The protein expression was assessed by Western blot analysis.RESULTS: A dose-dependent inhibitory effect of propofol was observed in cytochrome P450 3A4 activity. A minimal dosage of propofol (0.01 mM) induced a significant inhibition of P450 3A4 activity, although its regular dosages (0.01-0.1mM) showed no inhibitory effect on the cellular protein expression of P450 3A4.CONCLUSION: Propofol may be a potential CYP3A4 inhibitor as this anesthetic can inhibit isoenzyme activity significantly and reduce the metabolic rate of CYP3A4 substrates. This inhibition occurs at post-expression level, and concentration of propofol used clinically does not affect CYP3A4 protein expression. propofol may thus induce drug interaction of cytochrome P450 3A4 activity at the dosage used clinically. | Li-QunYang Wei-FengYu Yun-FeiCao BinGong QingChang Guang-ShunYang | 2003 | World Journal of Gastroenterology2003，9，9： | 4 |

| 8 | TEM observation of precipitation phase produced during tempering of steel AerMet100 and first principles calculations of phase evolution显示文摘The microstructure evolution law and the structure of precipitates produced during the tempering of steel AerMet100 based on TEM observation and the calibration of diffraction spot were revealed.The electronic structure and the stability of the MoxCr2-xC phase were calculated using the plane-wave pseudo-potential method on basis of density functional theory.TEM observations show that the precipitation phases Fe3C and Fe2-xCx(x=0.05~0.14) between martensite lath are produced at 425 and 480 ℃,respectively.The increase of tempering temperature or time can lead to the redissolution of both phases Fe3C and Fe2-xCx,and also lead to the precipitation of the phase Cr2C in martensite lath.The calculation results of formation energies and the density of state(DOS) demonstrate that in point of MoxCr2-xC structures formed during tempering,the early precipitation phase is Cr2C and finally later evolves into Mo2C phase with diffusing of incorporation of Mo atom into the Cr2C crystal cell,lattice,which can results in a energy decreases of the structure MoxCr2-xC phase with the increase of | WANG Xiangrong,YAN Mufu,and MENG Qingchang School of Materials Science and Engineering,Harbin Institute of Technology,Harbin 150001,China | 2007 | Rare Metals2007，26，S1： | 3 |
| 9 | Effect of octreotide on human pancreatic cancer cells after transfected with somatostatin receptor type 2 gene显示文摘AIM: To observe the effect of octreotide on apoptosis rate of human pancreatic cancer cells PC-3 after transfected with somatostatin receptor type 2 (SST2) gene.METHODS: SST2 plasmid was transfected into PC-3 cells by liposome. Result of transfection was detected by immunocytochemical staining and Western blotting.Apoptosis rates of PC-3 cells under different dosages of octreotide were measured by MTT assay and flow cytometry (FCM).RESULTS: Apoptosis rate caused by octreotide of transfected PC-3 cells was 7.56+2.06% at the dosage of 0.20 μg/mL, 9.25+1.73% at the dosage of 0.40 μg/mL and 14.28±2.72% at the dosage of 0.80 μg/mL. Apoptosis rate caused by octreotide of non-transfected PC-3 cells was 5.76+0.75% at the dosage of 0.20 μg/mL, 6.69±0.80% at the dosage of 0.d0 μg/mL and 7.26±1.28% at the dosage of 0.80 μg/mL. Transfected PC-3 cells growth inhibition rate caused by octreotide was 9.36+1.34% at the dosage of 0.20 μg/mL, 12.03+1.44% at the dosage of 0.40 μg/mL and 20.23+4.21% at the dosage of 0.80 μg/mL. Non-transfected PC-3 cells growth inhibition rate caused by octreotide was 6.44+0.66% at the dosage of 0.20 μg/mL,7.65+0.88% at the dosage of 0.40 μg/mL and 9.29+1.32% at the dosage of 0.80 μg/mL. We found that octreotidecaused higher apoptosis rate and inhibition rate in transfected groups than in non-transfected groups (P<0.05)at the tested dosages (0.20, 0.40 and 0.80 μg/mL).CONCLUSION: Deficiency of SST2 was probably the major reason why octreotide had little effect on PC-3 cells.Transfecting SST2 gene could strengthen the ability of octreotide of killing PC-3 cells. It provided an experimental evidence for using both octreotide and transfection with SST2 gene on clinical treatment of pancreatic cancer. | Zheng-RenLiu Ren-YiQin Gao-SongWu QingChang Da-YuWang Sheng-QuanZou Fa-ZuQiu | 2004 | World Journal of Gastroenterology2004，10，15： | 3 |

| 13 | Comparative transcriptome analysis of purple-fleshed sweet potato provides insights into the molecular mechanism of anthocyanin biosynthesis显示文摘Sweet potato, Ipomoea batatas, is a globally important food crop. The purple-fleshed sweet potato, rich in anthocyanins, has great potential for both nutritional and pharmaceutical uses. In this study, we characterized the root transcriptomes of the purple-fleshed sweet potato cv.Jingshu 6 and its mutant JS6-5 with high anthocyanin content by high-throughput RNA sequencing. A total of22873364 and 27955097 high quality reads were obtained from Jingshu 6 and JS6-5, respectively, and assembled into35592 unigenes. In all, we obtained 1566 differentially expressed genes(DEGs). Among them, 994 were upregulated and 572 were downregulated in JS6-5 compared to the expression in Jingshu 6. A total of 1436 DEGs were annotated, in which 847 DEGs had gene ontology(GO) terms and 329 DEGs were assigned to 84 Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways. Most importantly, 23 differentially expressed genes and 24 transcription factors were identified as candidate genes involved in anthocyanin biosynthesis. In addition, 2349 SSRs were detected. This study not only provides the candidate genes but also provides insights into the molecular mechanism of anthocyanin biosynthesis in sweet potato. | Hongyuan ZHAO Shanshan ZHANG Feibing WANG Ning ZHAO Shaozhen HE Qingchang LIU Hong ZHAI | 2018 | Frontiers of Agricultural Science and Engineering2018，5，2： | 2 |
| 14 | Development of a high-density SSR genetic linkage map in sweet potato显示文摘Simple sequence repeat(SSR) markers have been proved to be a very powerful tool for quantitative trait locus(QTL) mapping, marker-assisted selection and comparative genomics research in many crop species. However, a high-density SSR genetic linkage map is still lacking because there are only a few SSR markers available in sweet potato. In this study, a total of 2545 simple sequence repeat(SSR) primer pairs, including 1215 genomic SSR(gSSR) primer pairs and 1330 BES-SSR(bSSR) primer pairs designed from the genome sequence and BAC-end sequence of sweet potato, respectively, were screened with sweet potato cultivars Luoxushu 8 and Zhengshu 20 and their randomly sampled two F1 individuals and 571 of them generated polymorphic bands. The selected 571 polymorphic SSR primer pairs and 35 EST-based SSR(eSSR) primer pairs developed at our laboratory were used to genotype 240 F1 individuals derived from a cross between Luoxushu 8 and Zhengshu 20. A double pseudo-test-cross strategy was applied for linkage analysis. The Luoxushu 8 map included 90 linkage groups with 5057 SSR markers and covered 13,299.9 cM with a marker density of 2.6 cM, and the Zhengshu 20 map contained 90 linkage groups with 3009 SSR markers and covered 11,122.9 cM with a marker density of 3.7 cM. Fifteen homologous groups were identified in both parent maps. These are the first SSR linkage maps consisting of the complete 90 linkage groups and 15 homologous groups, which are consistent with the autohexaploid nature of sweetpotato, and are also the linkage maps with the highest SSR marker density reported to date.These results provide a basis for QTL mapping, marker-assisted breeding and comparative genomics research of sweet potato. | Yusha Meng Chenxing Zheng Hui Li Aixian Li Hong Zhai Qingmei Wang Shaozhen He Ning Zhao Huan Zhang Shaopei Gao Qingchang Liu | 2021 | The Crop Journal2021，9，6： | 2 |

| 16 | Modeling and Control of a V2G Charging Station Based on Synchronverter Technology显示文摘This paper proposes an idea for modeling and con-trol of a V2G charging station(CS)for electric vehicles(EVs)by using synchronverter technology.First,the architecture of the CS is introduced.Then,a T-S fuzzy controller is designed to decide the reference real power of the synchronverter by considering the grid frequency.Due to the inner frequency-and voltage-drooping mechanisms of the synchronverter,the input and output real and reactive power of the CS will be automatically adjusted on the basis of the reference value according to the degree of deviation from the nominal value of the grid frequency and voltage.To ensure the safety of this operation,an adaptive frequency droop coefficient mechanism is designed to adapt the change of the total energy storage of a CS unit by changing the slope of the P-f control characteristic of the synchronverter.The performance of the CS with the proposed control strategy is investigated with EVs of different battery states,different users’sets and under different grid status.Simulation results demonstrate that the proposed strategy can not only effectively perform controlled charging/discharging of each single electric vehicle inside the CS,but also improve the performance of the electricity grid in terms of efficiency,stability and reliability. | Dongqi Liu Qingchang Zhong Yaonan Wang Guorong Liu | 2018 | CSEE Journal of Power and Energy Systems2018，4，3： | 2 |
