| 2 | Significance of ultrasound evaluation of carotid atherosclerotic plaque for diagnosing ischemic cerebrovascular disease显示文摘BACKGROUND: Carotid artery is the main source for craniocerebral blood supply. Its intimal plaque formation and arterial stenosis degree both are the risk factors for ischemic cerebrovascular disease. Therefore, the close relationship of carotid atherosclerotic plaque and ischemic cerebrovascular disease, and ultrasound evaluation of carotid atherosclerotic plaque have become the hot spot in studying ischemic cerebrovascular disease. OBJECTIVE: This study was to detect the degree of carotid atherosclerosis of ischemic cerebrovascular disease patients by ultrasonography, and to analyze the situation of carotid atherosclerosis and its relationship with clinic. DESIGN: Clinical randomized concurrent control experiment. SETTING: Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA. PARTICIPANTS: Totally 60 outpatients and inpatients with ischemic cerebrovascular disease, 42 males and 18 females, admitted to Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA between January 2006 and December 2006 were involved in the patient group. They met the diagnosis criteria of ischemic cerebrovascular disease constituted by the 4th Cerebrovascular Disease Conference in 1996, and were confirmed to suffer from ischemic cerebrovascular disease by skull CT and MRI. Another 20 subjects who received healthy examination concurrently in the same hospital, 12 males and 8 females, were involved in the control group. Informed consents of detected items were obtained from involved subjects. METHODS: The plaque thickness of mid portion, distal end and crotch of common carotid artery (CCA), internal carotid artery (ICA), external carotid artery (ECA) and vertebral artery (VA) of involved subjects, who received health examination was separately detected with color Doppler ultrasonograph (HDI-5000). Then, total integral of plaque was calculated. The intima-media thickness (IMT) was measured with two-dimensional ultrasonography. The inner diameter stenosis degree of subjects who had plaque was measured. Blood flow parameters were recorded, and stenosis degree and plaque area were calculated. Blood flow volume of bilateral carotid artery and VA was separately measured with ultrasound equipment software, and brain blood flow volume was calculated. MAIN OUTCOME MEASURES: Atherosclerotic degree and blood flow volume of patients of two groups. RESULTS: Sixty patients with ischemic cerebrovascular disease and twenty subjects who received health examination participated in the final analysis. ①The IMT thickness, total plaque score, and total plaque area of patient group was significantly superior to that of control group, respectively(t=5.216–10.158,P < 0.05). ② There were significant differences in the stenosis degree of CCA, ICA and VA between patient group and control group (t=6.720–12.816,P < 0.05). ③ The blood flow volume of CCA, ICA, VA and brain of patient group was significantly lower than that of control group, respectively (t=2.872–10.860, P < 0.05). CONCLUSION: Ischemic cerebrovascular disease patients have different degrees of changes in atherosclerosis and arterial blood flow. | Li Gu Yaqin Feng Liwen Liu Liping Yang Lili He | 2007 | Neural Regeneration Research2007，2，7： | 7 |
| 3 | The R2R3-MYB transcription factor GhMYB1a regulates flavonol and anthocyanin accumulation in Gerbera hybrida显示文摘Anthocyanins and flavonols have vital roles in flower coloration,plant development,and defense.Because anthocyanins and flavonols share the same subcellular localization and common biosynthetic substrates,these pathways may compete for substrates.However,the mechanism regulating this potential competition remains unclear.Here,we identified GhMYB1a,an R2R3-MYB transcription factor involved in the regulation of anthocyanin and flavonol accumulation in gerbera(Gerbera hybrida).GhMYB1a shares high sequence similarity with that of other characterized regulators of flavonol biosynthesis.In addition,GhMYB1a is also phylogenetically grouped with these proteins.The overexpression of GhMYB1a in gerbera and tobacco(Nicotiana tabacum)resulted in decreased anthocyanin accumulation and increased accumulation of flavonols by upregulating the structural genes involved in flavonol biosynthesis.We further found that GhMYB1a functions as a homodimer instead of interacting with basic helix-loop-helix cofactors.These results suggest that GhMYB1a is involved in regulating the anthocyanin and flavonol metabolic pathways through precise regulation of gene expression.The functional characterization of GhMYB1a provides insight into the biosynthesis and regulation of flavonols and anthocyanins. | Chunmei Zhong Yi Tang Bin Pang Xukun Li Yuping Yang Jing Deng Chengyong Feng Lingfei Li Guiping Ren Yaqin Wang Jianzong Peng Shulan Sun Shan Liang Xiaojing Wang | 2020 | Horticulture Research2020，7，1： | 7 |
| 4 | Analyses of oligodontia phenotypes and genetic etiologies显示文摘Oligodontia is the congenital absence of six or more teeth and comprises the more severe forms of tooth agenesis.Many genes have been implicated in the etiology of tooth agenesis,which is highly variable in its clinical presentation.The purpose of this study was to identify associations between genetic mutations and clinical features of oligodontia patients.An online systematic search of papers published from January 1992 to June 2021 identified 381 oligodontia cases meeting the eligibility criteria of causative gene mutation,phenotype description,and radiographic records.Additionally,ten families with oligodontia were recruited and their genetic etiologies were determined by whole-exome sequence analyses.We identified a novel mutation in WNT10A(c.99_105dup)and eight previously reported mutations in WNT10A(c.433 G>A;c.682 T>A;c.318 C>G;c.511.C>T;c.321 C>A),EDAR(c.581 C>T),and LRP6(c.1003 C>T,c.2747 G>T).Collectively,20 different causative genes were implicated among those 393 cases with oligodontia.For each causative gene,the mean number of missing teeth per case and the frequency of teeth missing at each position were calculated.Genotype–phenotype correlation analysis indicated that molars agenesis is more likely linked to PAX9 mutations,mandibular first premolar agenesis is least associated with PAX9 mutations. | Mengqi Zhou Hong Zhang Heather Camhi Figen Seymen Mine Koruyucu Yelda Kasimoglu Jung-Wook Kim Hera Kim-Berman Ninna M.R.Yuson Paul J.Benke Yiqun Wu Feng Wang Yaqin Zhu James P.Simmer Jan C-C.Hu | 2021 | International Journal of Oral Science2021，13，3： | 5 |
| 5 | Protic vs aprotic ionic liquid for CO2 fixation:A simulation study显示文摘The cycloaddition of CO2 with epoxides catalyzed by ionic liquids(ILs)has been a widely ongoing studied hot topic over the years.Recent experimental research has shown that the protic ionic liquids(PILs)behave stronger hydrogen proton donating ability than aprotic ionic liquids(APILs),and can effectively catalyze the cycloaddition of CO2.Unfortunately,the mechanistic explanation remains primarily unraveled.Herein,a detailed simulation study on the cycloaddition reaction catalyzed by PIL([HDBU][Mim])in comparison with APIL([MeDBU][Mim])re-action catalysts was conducted,including the three-step route(ring-opening of PO(propylene oxide),insertion of CO2 and ring-closure of propylene carbonate(PC))and two-step route(simultaneously ring-opening of PO and addition of CO2,and then ring-closure of PC).Based on the activation energy barrier of the rate-determining step,PIL preferentially activates PO as the optimal route for the reaction with the energy barrier of 23.2 kcal mol-1,while that of APIL is 31.2 kcal mol-1.The role of[HDBU]+in the reaction was also explored and found that the direct formation of intermolecular hydrogen bond(H-bond)between[HDBU]+and the reactants(PO+CO2)was unfavorable for the reaction,while the cooperation with the anion[Mim]-to assist indirectly was more conducive.To fully consider the reaction microenvironment of ILs,ONIOM calculation was used to study the solvent effect.At last,the above conclusions were further verified by the analysis of intermediates with charge,non-covalent interaction(NCI),and atoms in molecules(AIM)methods.The computational findings show that ILs studied in this work have dual functions of catalyst and solvent,enabling a microscopic understanding of the ILs catalyst for CO2 utilization as well as providing guidance for the rational design of more efficient ILs-based catalysts. | Wenzhong Sun Meichen Wang Yaqin Zhang Weilu Ding Feng Huo Li Wei Hongyan He | 2020 | Green Energy & Environment2020，5，2： | 4 |

| 7 | Structures and Electrochemical Performances of As-spun RE-Mg-Ni-Mn-based Alloys Applied to Ni-MH Battery显示文摘The La-Mg-Ni-Mn-based AB_2-type La_(1-x)Ce_xMgNi_(3.5)Mn_(0.5)(x = 0, 0.1, 0.2, 0.3, and 0.4) alloys were fabricated by melt spinning technology. The effects of Ce content on the structures and electrochemical hydrogen storage performances of the alloys were studied systematically. The XRD and SEM analyses proved that the experimental alloys consist of a major phase LaMgNi_4 and a secondary phase LaNi_5. The variation of Ce content causes an obvious change in the phase abundance of the alloys without changing the phase composition. Namely, with the increase of Ce content, the LaMgNi_4 phase augments and the LaNi_5 phase declines. The lattice constants and cell volumes of the alloys clearly shrink with increasing Ce content. Moreover, the Ce substitution for La results in the grains of the alloys clearly refined. The electrochemical tests showed that the substitution of Ce for La obviously improves the cycle stability of the as-spun alloys. The analyses on the capacity degradation mechanism demonstrate that the improvement can be attributed to the ameliorated anti-corrosion and antioxidation ability originating from substituting partial La with Ce. The as-spun alloys exhibit excellent activation capability, reaching the maximum discharge capacities just at the first cycling without any activation treatment. The substitution of Ce for La evidently improves the discharge potential characteristics of the as-spun alloys. The discharge capacity of the alloys first increases and then decreases with growing Ce content. Furthermore, a similar trend also exists in the electrochemical kinetics of the alloys, including the high rate discharge ability(HRD), hydrogen diffusion coefficient(D), limiting current density(IL) and charge transfer rate. | 张羊换 SHANG Hongwei LI Yaqin YUAN Zeming HU Feng QI Yan ZHAO Dongliang | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，4： | 2 |

| 14 | Binding of Euplotes octocarinatus centrin with target peptide melittin显示文摘Interactions between model target peptide melittin (ME) and Euplotes octocarinatus centrin (EoCen) were investigated by fluorescence spectra, circular dichroism (CD) spectra and native polyacrylamide gel electrophoresis (PAGE). In 0.1 mol/L N-2-hydroxyethylpiperazine-N-2-ethanesulfonic acid (Hepes) and 150 mmol/L NaCl at pH 7.4, EoCen and isolated short C-terminal domain of EoCen (SC-EoCen) form 1:1 peptide:protein complexes. However, no detectable signal changes can be observed while isolated N-terminal domain of EoCen (N-EoCen) or isolated long C-terminal domain of EoCen (LC-EoCen) was added into solution of ME. The interaction between EoCen and ME is specified exclusively for the short C-terminal domain of EoCen. On the basis of fluorescence titration curves, the conditional binding constants of ME with EoCen and SC-EoCen were calculated to be logKME-EoCen = 6.81±0.33 and log- KME-SC-EoCen = 6.51±0.45, respectively. | ZHAO YaQin FENG JiuYing LIANG AiHua YANG BinSheng | 2007 | Chinese Science Bulletin2007，52，23： | 1 |

| 18 | Variants of the Mitochondrial Displacement Loop in Patients with Myelodysplastic Syndromes显示文摘OBJECTIVE Some mtDNA mutations have been detected in patients with myelodysplastic syndromes(MDSs).As the non-coding region of mitochondria,the displacement loop(D-loop) region of mtDNA contains important elements for mtDNA replication and transcription.Variants of the D-loop region were found to be related to the cause of many diseases.The aim of our study was to investigate mutations and single nucleotide polymorphisms in the D-loop region of MDS patients.METHODS The mutations and SNPs in the hypervariable regions of the D-loop were detected by direct sequencing in MDS patients and normal controls.RESULTS Sixty-four SNPs were found in the D-loop region in MDS cases and control group.Among the SNPs,the 16,189 variant(T > C transition) was found to have an increased frequency in the MDS group(P = 0.044).However,no mutations were detected in neither group.CONCLUSION Our data provide evidence for a highly polymorphic D-loop region in patients with MDS,but do not support the presence of mutations in the mitochondrial D-loop region in MDS cases.The mtDNA T16,189C variant,which may be a functional variant,is associated with increased susceptibility to a MDS. | Xiaojing Hu Yaqin Cong Conggao Xu Jinbo Feng Yujie Jiang Hong Jin | 2008 | Chinese Journal of Clinical Oncology2008，5，5： | 0 |
| 19 | Subsoil tillage enhances wheat productivity,soil organic carbon and available nutrient status in dryland fields显示文摘Tillage practices during the fallow period benefit water storage and yield in dryland wheat crops.However,there is currently no clarity on the responses of soil organic carbon(SOC),total nitrogen(TN),and available nutrients to tillage practices within the growing season.This study evaluated the effects of three tillage practices(NT,no tillage;SS,subsoil tillage;DT,deep tillage)over five years on soil physicochemical properties.Soil samples at harvest stage from the fifth year were analyzed to determine the soil aggregate and aggregate-associated C and N fractions.The results indicated that SS and DT improved grain yield,straw biomass and straw carbon return of wheat compared with NT.In contrast to DT and NT,SS favored SOC and TN concentrations and stocks by increasing the soil organic carbon sequestration rate(SOCSR)and soil nitrogen sequestration rate(TNSR)in the 0-40 cm layer.Higher SOC levels under SS and NT were associated with greater aggregate-associated C fractions,while TN was positively associated with soluble organic nitrogen(SON).Compared with DT,the NT and SS treatments improved soil available nutrients in the 0-20 cm layer.These findings suggest that SS is an excellent practice for increasing soil carbon,nitrogen and nutrient availability in dryland wheat fields in North China. | Qiuyan Yan Linjia Wu Fei Dong Shuangdui Yan Feng Li Yaqin Jia Jiancheng Zhang Ruifu Zhang Xiao Huang | 2024 | Journal of Integrative Agriculture2024，23，1： | 0 |
