| 1 | Simvastatin inhibits apoptosis of endothelial cells induced by sepsis through upregulating the expression of Bcl-2 and downregulating Bax显示文摘BACKGROUND: Many studies have showed that apoptosis of endothelial cells plays a curial role in the progress of sepsis. But the role of simvastatin in apoptosis of endothelial cells induced by sepsis is not clear. The present study aimed to investigate the role of simvastatin in apoptosis of endothelial cells induced by sepsis and its mechanism.METHODS: Human umbilical vein endothelial cells(HUVECs) were randomly divided into three groups: control group, sepsis serum intervention group(sepsis group) and simvastatin+sepsis serum intervention group(simvastatin group). After 24-hour incubation with corresponding culture medium, the relative growth rate of HUVECS in different groups was detected by MTT assay; the apoptosis of HUVECs was detected by Hoechst33258 assay and fl ow cytometry; and the expression of the Bcl-2 and Bax genes of HUVECs was detected by PCR.RESULTS: Compared with the sepsis group, HUVECs in the simvastatin group had a higher relative growth rate. Apoptotic HUVECs decreased significantly in the simvastatin group in comparison with the sepsis group. Expression of the Bcl-2 gene in HUVECs decreased obviously, but the expression of the Bax gene increased obviously after 24-hour incubation with sepsis serum; however, the expression of the Bcl-2 and Bax genes was just the opposite in the simvastatin group.CONCLUSIONS: Our study suggests that simvastatin can inhibit apoptosis of endothelial cells induced by sepsis through upregulating the expression of Bcl-2 and downregulating Bax. It may be one of the mechanisms for simvastatin to treat sepsis. | Hui Fu Qiao-sheng Wang Qiong Luo Si Tan Hua Su Shi-lin Tang Zheng-liang Zhao Li-ping Huang | 2014 | World Journal of Emergency Medicine2014,5,4: | 18 |
| 2 | A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis. | Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao | 2016 | Chinese Journal of Cancer2016,35,6: | 10 |
| 3 | Generation of GGTA1 biallelic knockout pigs via zinc-finger nucleases and somatic cell nuclear transfer显示文摘Genetically modified pigs are valuable models of human disease and donors of xenotransplanted organs.Conventional gene targeting in pig somatic cells is extremely inefficient.Zinc-finger nuclease(ZFN)technology has been shown to be a powerful tool for efficiently inducing mutations in the genome.However,ZFN-mediated targeting in pigs has rarely been achieved.Here,we used ZFNs to knock out the porcineα-1,3-galactosyl-transferase(GGTA1)gene,which generates Gal epitopes that trigger hyperacute immune rejection in pig-to-human transplantation.Primary pig fibroblasts were transfected with ZFNs targeting the coding region of GGTA1.Eighteen mono-allelic and four biallelic knockout cell clones were obtained after drug selection with efficiencies of 23.4%and 5.2%,respectively.The biallelic cells were used to produce cloned pigs via somatic cell nuclear transfer(SCNT).Three GGTA1 null piglets were born,and one knockout primary fibroblast cell line was established from a cloned fetus.Gal epitopes on GGTA1 null pig cells were completely eliminated from the cell membrane.Functionally,GGTA1 knockout cells were protected from complement-mediated immune attacks when incubated with human serum.This study demonstrated that ZFN is an efficient tool in creating gene-modified pigs.GGTA1 null pigs and GGTA1 null fetal fibroblasts would benefit research and pig-to-human transplantation. | BAO Lei CHEN HaiDe JONG UiMyong RIM CholHo LI WenLing LIN XiJuan ZHANG Dan LUO Qiong CUI Chun HUANG HeFeng ZHANG Yan XIAO Lei FU ZhiXin | 2014 | Science China(Life Sciences)2014,57,2: | 9 |
| 4 | Type I interferons promote the survival and proinflammatory properties of transitional B cells in systemic lupus erythematosus patients显示文摘A hallmark of systemic lupus erythematosus(SLE)is the breaking of B-cell tolerance with the generation of high-affinity autoantibodies;however,the antibody-independent features of the B-cell compartment in SLE are less understood.In this study,we performed an extensive examination of B-cell subsets and their proinflammatory properties in a Chinese cohort of new-onset SLE patients.We observed that SLE patients exhibited an increased frequency of transitional B cells compared with healthy donors and rheumatoid arthritis patients.Plasma from SLE patients potently promoted the survival of transitional B cells in a type I IFN-dependent manner,which can be recapitulated by direct IFN-αtreatment.Furthermore,the effect of IFN-αon enhanced survival of transitional B cells was associated with NF-κB pathway activation and reduced expression of the pro-apoptotic molecule Bax.Transitional B cells from SLE patients harbored a higher capacity to produce proinflammatory cytokine IL-6,which was also linked to the overactivated type I IFN pathway.In addition,the frequency of IL-6-producing transitional B cells was positively correlated with disease activity in SLE patients,and these cells were significantly reduced after short-term standard therapies.Thus,the current study provides a direct link between type I IFN pathway overactivation and the abnormally high frequency and proinflammatory properties of transitional B cells in active SLE patients,which contributes to the understanding of the roles of type I IFNs and B cells in the pathogenesis of SLE. | Mei Liu Qiang Guo Chunmei Wu Delphine Sterlin Shyamal Goswami Ying Zhang Teng Li Chunde Bao Nan Shen Qiong Fu Xiaoming Zhang | 2019 | Cellular & Molecular Immunology2019,16,4: | 9 |
| 5 | Total flavonoids of hawthorn leaves promote motor function recovery via inhibition of apoptosis after spinal cord injury显示文摘Flavonoids have been reported to have therapeutic potential for spinal cord injury.Hawthorn leaves have abundant content and species of total flavonoids,and studies of the effects of the total flavonoids of hawthorn leaves on spinal cord injury have not been published in or outside China.Therefore,Sprague-Dawley rats were used to establish a spinal cord injury model by Allen's method.Rats were intraperitoneally injected with 0.2 m L of different concentrations of total flavonoids of hawthorn leaves(5,10,and 20 mg/kg)after spinal cord injury.Injections were administered once every 6 hours,three times a day,for 14 days.After treatment with various concentrations of total flavonoids of hawthorn leaves,the Basso,Beattie,and Bresnahan scores and histological staining indicated decreases in the lesion cavity and number of apoptotic cells of the injured spinal cord tissue;the morphological arrangement of the myelin sheath and nerve cells tended to be regular;and the Nissl bodies in neurons increased.The Basso,Beattie,and Bresnahan scores of treated spinal cord injury rats were increased.Western blot assays showed that the expression levels of pro-apoptotic Bax and cleaved caspase-3 were decreased,but the expression level of the anti-apoptotic Bcl-2 protein was increased.The improvement of the above physiological indicators showed a dose-dependent relationship with the concentration of total flavonoids of hawthorn leaves.The above findings confirm that total flavonoids of hawthorn leaves can reduce apoptosis and exert neuroprotective effects to promote the recovery of the motor function of rats with spinal cord injury.This study was approved by the Ethics Committee of the Guangxi Medical University of China(approval No.201810042)in October 2018. | Qiong Zhang Yin Xiong Bo Li Gui-Ying Deng Wen-Wen Fu Bai-Chuan Cao Shao-Hui Zong Gao-Feng Zeng | 2021 | Neural Regeneration Research2021,16,2: | 8 |
| 6 | Climate controls on dust storm occurrence in Maowusu Desert, Inner Mongolia, North China显示文摘Dust storms occurring in arid and semi arid regions play a main role in the evolution of landscapes. Climate is generally regarded to be important factors influencing the occurrence of dust storm, however, the way of climate controlling dust storms had been poorly understood. In this paper, we present the Ew Index model to describe the relationship between climate variables and dust storm frequency using the available meteorological data from three meteorological stations in Maowusu Desert. This index model explains 83.6%, 69.5% and 65.09% of the variance of dust storm frequency in three regions from the north to the south, respectively and this difference is probably caused by the difference of the human disturbance. The Ew Index model is an effective predictor of dust storm frequency and provides us a quite good understanding on the occurrence of dust storms in Maowusu Desert. | HUANG Fu xiang, GAO Qiong (Laboratory of Quantitative Vegetation Ecology, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China.

| 7 | Safety and Efficacy of Physical Thermal Ablation Combined Sorafenib for Hepatocellular Carcinoma:A Meta-analysis显示文摘Background and Aims:To compare the efficacy and safety of physical thermal ablation(PTA),including radiofrequency ablation(RFA)and microwave ablation(MWA),combined with sorafenib and physical thermal ablation alone for the control and treatment of hepatocellular carcinoma(HCC)according to the available literature.Methods:Comprehensive searches were performed on PubMed,Embase,CNKI,the Cochrane Library,China Biomedical Literature Database(known as CBM),Weipu Journal,and Wanfang Database.Meta-analysis was performed using Revman 5.3 software.Results:A total of 15 studies,consisting of 2,227 HCC patients,were selected and included in this meta-analysis.Compared with the RFA-alone group,the patients in the RFA+sorafenib group had longer 1-,2-,and 3-year overall survival(all p<0.05),better overall efficacy(p<0.0001),longer radiofrequency interval(p<0.001),and lower 2-year recurrence rate(p=0.02).The 1-year overall survival(p=0.003)and overall efficacy(p=0.002)of the MWA+sorafenib group were also higher than those of the MWA-alone group.The incidences of adverse reactions in the RFA+sorafenib group,such as hand-foot skin reactions(p<0.001),diarrhea and constipation(p=0.0001),hypertension(p=0.009),and alopecia(p<0.001),were significantly higher than those in the RFA-alone group.Conclusions:RFA or MWA combined with sorafenib has produced a better therapeutic effect on HCC than physical thermal ablation alone;however,adverse reactions have been obvious.It is necessary to evaluate the safety of combination therapy,and pay close attention to the adverse reactions that develop in patients. | Mengdi Jin Qiong Yu Yahui Liu Weiling Xu Xueqi Fu Bai Ji | 2021 | Journal of Clinical and Translational Hepatology2021,9,2: | 6 |
| 8 | A double-blind, double-dummy, randomized controlled, multicenter trial of ^(99)Tc-methylene diphosphonate in patients with moderate to severe rheumatoid arthritis显示文摘Background:Clinical observational studies revealed that ^(99)Tc-methylene diphosphonate(^(99)Tc-MDP)could reduce joint pain and swollenness in rheumatoid arthritis(RA)patients.This multicenter,randomized,double-blind,double-dummy study aimed to evaluate the effects of ^(99)Tc-MDP plus methotrexate(MTX)vs.MTX alone or ^(99)Tc-MDP alone on disease activity and structural damage in MTX-naïve Chinese patients with moderate to severe RA.Methods:Eligible patients with moderate to severely active RA were randomized to receive ^(99)Tc-MDP plus MTX(n=59)vs.MTX(n=59)alone or ^(99)Tc-MDP(n=59)alone for 48 weeks from six study sites across four provinces in China.The primary outcomes were the American College of Rheumatology 20%improvement(ACR20)response rates at week 24 and changes in modified total Sharp score at week 48.Results:At week 24,the proportion of participants achieving ACR20 was significantly higher in the MTX+^(99)Tc-MDP combination group(69.5%)than that in the MTX group(50.8%)or ^(99)Tc-MDP group(47.5%)(P=0.03 for MTX+^(99)Tc-MDP vs.MTX,and MTX+^(99)Tc-MDP vs.^(99)Tc-MDP,respectively).The participants in the MTX+^(99)Tc-MDP group and the ^(99)Tc-MDP group had significantly less important radiographic progression than the participants in the MTX group over the 48 weeks(MTX+^(99)Tc-MDP vs.MTX:P=0.03,^(99)Tc-MDP vs.MTX:P=0.03,respectively).There was no significant difference in terms of adverse events(AEs)among the groups.No serious AEs were observed.Conclusions:This study demonstrated that the combination of ^(99)Tc-MDP with MTX inhibited structural damage and improved disease activity in RA patients compared with MTX and ^(99)Tc-MDP monotherapies,without increasing the rate of AEs.Additional clinical studies of ^(99)Tc-MDP therapy in patients with RA are warranted.Trial Registration:Chictr.org,ChiCTR-IPR-14005684;http://gffzz62a03ee25e6f4a77hfkuv5pqvn6vx6b5w.ffgz.tsg.suse.edu.cn/showproj.aspx?proj=10088. | Qiong Fu Ping Feng Ling-Yun Sun Xiao-Xia Zuo Dong-Bao Zhao Dong-Yi He Hua-Xiang Wu Wei Zhang Wei Zhang Fang Du Chun-De Bao | 2021 | Chinese Medical Journal2021,,12: | 5 |
| 9 | Variation in glomalin in soil profiles and its association with climatic conditions,shelterbelt characteristics,and soil properties in poplar shelterbelts of Northeast China显示文摘Glomalin-related soil protein(GRSP)sequesters large amounts of carbon and plays important roles in maintaining terrestrial soil ecosystem functions and ecological restoration;however,little is known about GRSP variation in 1-m soil profiles and its association with stand characteristics,soil properties,and climatic conditions,hindering GRSP-related degraded soil improvement and GRSP evaluation.In this study,we sampled soils from 1-m profiles from poplar(Populus spp.)shelterbelts in Northeast China.GRSP contents were 1.8–2.0 times higher in the upper 40 cm soil layers than at 40–100 cm.GRSP-related soil organic carbon(SOC)sequestration in deeper soil layers was*1.2 times higher than in surface layers.The amounts of GRSP-related nutrients were similar throughout the soil profile.A redundancy analysis showed that in both surface and deeper layers,soil properties(pH,electrical conductivity,water,SOC,and soil nutrients)explained the majority of the GRSP variation(59.5–84.2%);the second-most-important factor in GRSP regulation was climatic conditions(temperature,precipitation,and altitude),while specific shelterbelt characteristics had negligible effects(<5%).Soil depth and climate indirectly affected GRSP features via soil properties,as manifested by structural equation model analysis.Our findings demonstrate that GRSP is important for carbon storage in deep soils,regardless of shelterbelt characteristics.Future glomalin assessments should consider these vertical patterns and possible regulating mechanisms that are related to soil properties and climatic changes. | Qiong Wang Wenjie Wang Zhaoliang Zhong Huimei Wang Yujie Fu | 2020 | Journal of Forestry Research2020,31,1: | 5 |
| 10 | Mitochondrial localization of ORF346 causes pollen abortion in alloplasmic male sterility显示文摘The Nsa cytoplasmic male sterility(CMS) system confers stable male sterility and offers great potential for production of hybrid seeds in oilseed rape. However, genes responsible for male sterility in Nsa CMS have not been identified. By mitochondrial genome sequencing of Nsa CMS and its maintainer line,we identified in an Nsa CMS line several chimeric genes encoding hypothetical proteins harboring transmembrane domains. One novel chimeric gene orf346 showed high identity with cox1 at the 50 terminal region and was co-transcribed with nad3 and rps12 genes. Transgenic plants of orf346 fused with or without mitochondrial targeting peptide conferred complete male sterility in Arabidopsis. ORF346 was mitochondrion-localized. Expression of orf346 in Escherichia coli inhibited bacterial growth, with excessive accumulation of reactive oxygen species and decreased ATP content. These results reveal a link between the newly identified mitochondrial gene orf346 and the abortion of Nsa CMS. Inadequate energy supply and excessive accumulation of reactive oxygen species may account for pollen abortion in Nsa CMS plants. | Shifei Sang Hongtao Cheng Mengyu Hao Bingli Ding Desheng Mei Hui Wang Wenxiang Wang Jia Liu Li Fu Kede Liu Qiong Hu | 2021 | The Crop Journal2021,9,6: | 5 |
| 11 | Combining Ability and Breeding Potential of Rapeseed Elite Lines for Pod Shatter Resistance显示文摘Pod shatter resistance of rapeseed is of great importance for modern farming practice. In order to determine the combining ability of elite inbred lines and the breeding potential of rapeseed hybrids in terms of pod shatter resistance, analysis of a 6×6 incomplete diallel cross was conducted at two locations. Results showed that a significant variation existed among breeding lines and their F1 hybrids for pod shatter resistant index (SRI), pod length and width. Pod shatter resistance was significantly positively correlated with pod length. The general combining ability (GCA) effects (GCA=1.58) played a more important role than specific combining ability (SCA) effects (SCA=0.20) for pod shatter trait. The elite lines R1, 1019B and 1055B displayed significant positive GCA effects for pod shatter resistance. Four crosses (1019B×R1, 1015B×R1, 6098B×R1, and 8908B×R1) with high mean performance and positive SCA effects were recommended for developing new hybrids for mechanical harvest in the middle reaches of the Yangtze River. | LIU Jia MEI De-sheng LI Yun-chang CUI Jia-cheng WANG Hui PENG Peng-fei FU Li HU Qiong | 2013 | Journal of Integrative Agriculture2013,12,3: | 4 |

| 13 | Iso-structural phase transition in tetramethylammonium nickel(Ⅱ)nitrite[(CH_3)_4N][Ni(NO_2)_3]显示文摘The title compound,tetramethylammonium nickel nitrite[(CH_3)_4Nl[Ni(NO_2)_3],has a hexagonal perovskite-type structure with formula ABX_3.It undergoes two reversible phase transitions occurring at about 409.1 and 428.4 K,associated with dielectric transitions.DSC measurement and dielectric measurement confirm the transition.The variable-temperature X-ray structural determinations and the powder X-ray diffraction(PXRD) experiments reveal that this compound has the same space group P3 m 1(No.164) at 293 K,413 K and 438 K.The phase transitions are caused by the rotation of the[(CH_3)_4N]^+cation. | Li-Hui Kong Da-Wei Fu Qiong Ye Heng-Yun Ye Yi Zhang Ren-Gen Xiong | 2014 | Chinese Chemical Letters2014,25,6: | 3 |
| 14 | Epidemiological and clinical characteristics of COVID-19 patients in Hengyang,Hunan Province,China显示文摘BACKGROUND In December 2019,an ongoing outbreak of coronavirus disease 2019(COVID-19)was first identified in Wuhan,China.The characteristics of COVID-19 patients treated in local hospitals in Wuhan are not fully representative of patients outside Wuhan.Therefore,it is highly essential to analyze the epidemiological and clinical characteristics of COVID-19 in areas outside Wuhan or Hubei Province.To date,a limited number of studies have concentrated on the epidemiological and clinical characteristics of COVID-19 patients with different genders,clinical classification,and with or without basic diseases.AIM To study the epidemiological and clinical characteristics of COVID-19 patients in Hengyang(China)and provide a reliable reference for the prevention and control of COVID-19.METHODS From January 16 to March 2,2020,a total of 48 confirmed cases of COVID-19 were reported in Hengyang,and those cases were included in this study.The diagnostic criteria,clinical classification,and discharge standard related to COVID-19 were in line with the Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia(Trial Version 7)released by National Health Commission and National Administration of Traditional Chinese Medicine.The presence of SARS-CoV-2 in pharyngeal swab specimens was detected by quantitative reverse transcription polymerase chain reaction.All the data were imported into the excel worksheet and statistically analyzed by using SPSS 25.0 software.RESULTS A total of 48 cases of COVID-19 were collected,of which 1 was mild,38 were moderate,and 9 were severe.It was unveiled that there were 31(64.6%)male patients and 17(35.4%)female patients,with a female-to-male ratio of 1.82:1.The range of age of patients with COVID-19 was dominantly 30-49 years old[25(52.1%)of 48],followed by those aged over 60 years old[11(22.9%)].Besides,29.2%(14 of 48)of patients had basic diseases,and 57.2%(8 of 14)of patients with basic diseases were aged over 60 years old.The occupations of 48 COVID-19 patients were mainly farmers working in agricultural production[15(31.5%)of 48],rural migrant workers from Hengyang to Wuhan[15(31.5%)],and service workers operating in the service sector[8(16.7%)].The mean latent period was 6.86±3.57 d,and the median was 7[interquartile range(IQR):4-9]d.The mean time from onset of symptoms to the first physician visit was 3.38±2.98(95%CI:2.58-9.18)d,with a median of 2(IQR:1-5)d,and the mean time from hospital admission to confirmed diagnosis was 2.29±2.11(95%CI:1.18-6.42)d,with a median of 2(IQR:1-3)d.The main symptoms were fever[43(89.6%)of 48],cough and expectoration[41(85.4%)],fatigue[22(45.8%)],and chills[22(45.8%)].Other symptoms included poor appetite[13(27.1%)],sore throat[9(18.8%)],dyspnea[9(18.8%)],diarrhea[7(14.6%)],dizziness[5(10.4%)],headache[5(10.4%)],muscle pain[5(10.4%)],nausea and vomiting[4(8.3%)],hemoptysis[4(8.3%)],and runny nose[1(2.1%)].The numbers of peripheral blood leukocytes,lymphocytes,and eosinophils were significantly reduced in the majority of the patients.The levels of C-reactive protein,fibrinogen,blood glucose,lactate dehydrogenase,Ddimer,alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl transferase(γ-GT),myoglobin(MB),and creatine kinase(CK)were increased in 64.6%,44.7%,43.2%,37.0%,29.5%,22.9%,20.8%,21.6%,13.6%,and 12.8%of patients,respectively.The incidence of ALT elevation in male patients was remarkably higher than that in females(P<0.01),while the incidences of AST,CK,and blood glucose elevations in severe patients were remarkably higher than those in moderate patients(P<0.05,respectively).Except for the mild patients,chest computed tomography showed characteristic pulmonary lesions.All the patients received antiviral drugs,38(79.2%)accepted traditional Chinese medicine,and 2(4.2%)received treatment of human umbilical-cord mesenchymal stem cells.On March 2,2020,48 patients with COVID-19 were all cured and discharged.CONCLUSION Based on our results,patients with COVID-19 often have multiple organ dysfunction or damage.The incidences of ALT elevation in males,and AST,CK,and blood glucose elevations in severe patients are remarkably higher. | Zhe-Feng Zhong Jia Huang Xia Yang Jin-Ling Peng Xiao-Yan Zhang Yang Hu Nian Fu Hai-Lian Lin Bo Jiang Ya-Ying Tian Hong-Yi Yao Li-Pu Deng Xiao-Qing Tang Jie-Can Zhou Jian Tang Xia Xie Qiong Liu Jing Liu Cheng-Yun Dou Rong-Juan Dai Bo Yan Xue-Feng Yang | 2020 | World Journal of Clinical Cases2020,8,12: | 3 |
| 15 | Facile fabrication of CeF_(3)/g-C_(3)N_(4) heterojunction photocatalysts with upconversion properties for enhanced photocatalytic desulfurization performance显示文摘Cerium fluoride(CeF_(3))semiconductor with upconversion property was constructed on graphite carbonitride(g-C_(3) N_(4))nanosheets by microwave hydrothermal method.The X-ray diffraction,transmission election microscopy,Fourier transform infrared,and X-ray photoelectron spectra techniques were used to characterize the CeF_(3)/g-C_(3)N_(4) nanocomposite.The study shows that CeF_(3) has upconversion property and can convert visible light(Vis)and near-infrared light(NIR)into ultraviolet light(UV).Mo reover,CeF3 and g-C_(3) N_(4) can form well-defined heterojunction and promote the effective separation of photogenerated electrons and holes.The synergistic effect of the CeF_(3)/g-C_(3)N_(4) nanocomposite was evaluated by photocatalytic degradation of dibenzothiophene(DBT).The optimum photocatalyst of CeF_(3)/g-C_(3)N_(4)(40 wt%)composites exhibit the highest photocatalytic desulfurization rate of the model oil under visible light radiation. | Xiaowang Lu Feng Chen Junchao Qian Meng Fu Qiong Jiang Qinfang Zhang | 2021 | Journal of Rare Earths2021,39,10: | 3 |
| 16 | Characterization and Proteomic Analysis of Novel Rice Lesion Mimic Mutant with Enhanced Disease Resistance显示文摘Lesion mmic mutants(LMMs)are plants that spontaneously form lesions without pathogeninfection or external stimulus and exhibit resistance to pathogens.Here,a rice LMM was created by ethylmethane sulfonate mutagenesis,named as hpil(hydrogen peroxide induced lesion).Diaminobenzidineand trypan blue staining showed that large amounts of H_(2)O_(2) were produced and cell death was occurredat and around the parts of lesion mimic in the rice leaves.The phenotype of hpil is controlled by a singlerecessive gene,localized at a 2 Mb interval on chromosome 2.The data suggested that hpil is a novelLMM with enhanced bacterial and fungal disease resistance,and multiple pathogenesis-related proteins(PRs)were up-regulated.The proteomes of leaves at three positions(different degrees of lesion mimicseverity)were characterized in hpil compared with its wild type plant.Differentially expressed proteinswere detected by two dimensional difference gel electrophoresis and 274 proteins were identified byMALDITOF/TOFTM.These proteins were related to metabolic process,cellular process and response tostimulus,with mostly down-regulated in hpil leaves.Many of these proteins were related to the Calvincycle,photosynthetic electron transport chain,glycolysis/gluconeogenesis and phosphonates pathways.Some resistance-related proteins including 14-3-3 proteins,OsPR10 and antioxidases such asperoxidase,superoxide dismutase and ascorbate peroxidase were up-regulated in leaves with lesionmimic.These results provide the foundation for cloning of the target gene and shed light on themechanism involved in autaimmunity of rice. | Yang Yong Lin Qiujun Chen Xinyu Liang Weifang Fu Yuwen Xu Zhengjin Wu Yuanhua Wang Xuming Zhou Jie Yu Chulang Yan Chengqi Mei Qiong Chen Jianping | 2021 | Rice science2021,28,5: | 2 |
| 17 | Facile preparation of hydrophilic glutathione modified magnetic nanomaterials for specific enrichment of glycopeptides显示文摘Investigations of glycosylated proteins or peptides and their related biological pathways provide new possibilities for illuminating the physiological and pathological mechanisms of glycosylation modification.However,open-ended and in-depth analysis of glycoproteomics is usually subjected to the low-abundance of glycopeptides,heterogeneous glycans,and a variety of interference molecules.In order to alleviate the influence of these obstacles,effective preconcentration of glycopeptides are indispensable.Here,we employed a hydrophilic interaction liquid chromatography(HILIC)-based method to universally capture glycopeptides.Glutathione modified magnetic nanoparticles(Fe304@AuGSH) were synthesized through a simple process and exploited to enrich glycopeptides from complex samples.The prepared materials showed excellent ability to trap glycopeptides from standard glycoproteins digests,low detection limit(10 fmol/p L),and good selectivity(HRP:BSA=1:100).These results indicated that glutathione-based magnetic nanoparticles synthesized in this work had great potential for glycopeptides enrichment. | He Qi Zheng Li Haijiao Zheng Li Fu Qiong Jia | 2019 | Chinese Chemical Letters2019,30,12: | 2 |
| 18 | Ecdysone receptor isoforms play distinct roles in larval–pupal–adult transition in Leptinotarsa decemlineata显示文摘A heterodimer of two nuclear receptors,ecdysone receptor(EcR)and ultraspiracle,mediates 20‐hydroxyecdysone(20E)signaling to modulate many aspects in insect life,such as molting and metamorphosis,reproduction,diapause and innate immunity.In the present paper,we intended to determine the isoform‐specific roles of EcR during larval–pupal–adult transition in the Colorado potato beetle.Double‐stranded RNAs(dsRNAs)were prepared using the common(dsEcR)or isoform‐specific(dsEcRA,dsEcRB1)regions of EcR as templates.Ingestion of either dsEcR or dsEcRA,rather than dsEcRB1,by the penultimate(3rd)and final(4th)instar larvae caused failure of larval–pupal and pupal–adult ecdysis.The RNA interference(RNAi)larvae remained as prepupae,or became deformed pupae and adults.Determination of messenger RNA(mRNA)levels of EcR isoforms found that LdEcRA regulates the expression of LdEcRB1.Moreover,silencing the two EcR transcripts,LdEcRA or LdEcRB1 reduced the mRNA levels of Ldspo and Ldsad,and lowered 20E titer.In contrast,the expression levels of HR3,HR4,E74 and E75 were significantly decreased in the LdEcR or LdEcRA RNAi larvae,but not in LdEcRB1 depleted specimens.Dietary supplement with 20E did not restore the expression of five 20E signaling genes(USP,HR3,HR4,E74 and E75),and only partially alleviated the pupation defects in dsEcR‐or dsEcRA‐fed beetles.These data suggest that EcR plays isoform‐specific roles in the regulation of ecdysteroidogenesis and the transduction of 20E signal in L.decemlineata. | Qing-Yu Xu Pan Deng Qiong Zhang Ang Li Kai-Yun Fu Wen-Chao Guo Guo-Qing Li | 2020 | Insect Science2020,27,3: | 2 |
| 19 | Design of Self‑Reconfigurable Multiarm Robot Mechanism Based on Deployable Kinematic Chains显示文摘As the structures of multiarm robots are serially arranged,the packaging and transportation of these robots are often inconvenient.The ability of these robots to operate objects must also be improved.Addressing this issue,this paper presents a type of multiarm robot that can be adequately folded into a designed area.The robot can achieve different operation modes by combining different arms and objects.First,deployable kinematic chains(DKCs)are designed,which can be folded into a designated area and be used as an arm structure in the multiarm robot mechanism.The strategy of a platform for storing DKCs is proposed.Based on the restrictions in the storage area and the characteristics of parallel mechanisms,a class of DKCs,called base assembly library,is obtained.Subsequently,an assembly method for the synthesis of the multiarm robot mechanism is proposed,which can be formed by the connection of a multiarm robot mechanism with an operation object based on a parallel mechanism structure.The formed parallel mechanism can achieve a reconfigurable characteristic when different DKCs connect to the operation object.Using this method,two types of multiarm robot mechanisms with four DKCs that can switch operation modes to perform different tasks through autonomous combination and release operation is proposed.The obtained mechanisms have observable advantages when compared with the traditional mechanisms,including optimizing the occupied volume during transportation and using parallel mechanism theory to analyze the switching of operation modes. | Fu‑Qun Zhao Sheng Guo Hai‑Jun Su Hai‑Bo Qu Ya‑Qiong Chen | 2020 | Chinese Journal of Mechanical Engineering2020,33,5: | 2 |
| 20 | Mesencephalic astrocyte-derived neurotrophic factor reduces cell apoptosis via upregulating HSP70 in SHSY-5Y cells显示文摘Background:Mesencephalic astrocyte-derived neurotrophic factor(MANF)is a new candidate growth factor for dopaminergic neurons against endoplasmic reticulum stress(ER stress).HSP70 family,a chaperon like heat shock protein family,was proved to be involved in the MANF induced survival pathway in 6-OHDA treated SHSY-5Y cells.However,the ER stress relative transcriptome,in MANF signaling cascades is still investigated.The involvement of HSP70,a 70kd member of HSP70 family,need further to be verified.Methods:The cell apoptosis was assayed by MTT,TUNEL staining and western blot of cleaved Caspase-3.The differentially expressed genes in SHSY-5Y cells under different conditions(control,6-OHDA,6-OHDA+MANF)were investigated by RNA-seq.Expression of HSP70 was further confirmed by real-time PCR.RNAi knockdown for HSP70 was performed to investigate the role of HSP70 in the MANF signaling pathway.Results:MANF inhibits 6-OHDA-induced apoptosis in SHSY-5Y cells.Six ER stress relative genes(HSP70,GRP78,xbp-1,ATF-4,ATF-6,MAPK)were found enriched in 6-OHDA+MANF treatment group.HSP70 was the most significantly up-regulated gene under 6-OHDA+MANF treatment in SHSY-5Y cells.RNAi knockdown for HSP70 inhibits the protective effects of MANF against 6-OHDA toxicity in SHSY-5Y cells.Conclusion:MANF exerts a protective role against 6-OHDA induced apoptosis in SHSY-5Y cells via up-regulating some ER stress genes,including HSP70 family members.The HSP70 expression level plays a key role in MANFmediated survival pathway. | Hui Sun Ming Jiang Xing Fu Qiong Cai Jingxing Zhang Yanxin Yin Jia Guo Lihua Yu Yun Jiang Yigang Liu Liang Feng Zhiyu Nie Jianmin Fang Lingjing Jin | 2017 | Translational Neurodegeneration2017,6,1: | 2 |
