1Oxidative stress, nutritional antioxidants and beyond显示文摘Free radical-induced oxidative stress contributes to the development of metabolic syndromes(Mets), including overweight,hyperglycemia, insulin resistance and pro-inflammatory state. Most free radicals are generated from the mitochondrial electron transport chain;under physiological conditions, their levels are maintained by efficient antioxidant systems. A variety of transcription factors have been identified and characterized that control gene expression in response to oxidative stress status.Natural antioxidant compounds have been largely studied for their strong antioxidant capacities. This review discusses the recent progress in oxidative stress and mitochondrial dysfunction in Mets and highlights the anti-Mets, anti-oxidative, and antiinflammatory effect of polyphenols as potential nutritional therapy.Qiuping Guo Fengna Li Yehui Duan Chaoyue Wen Wenlong Wang Lingyu Zhang Ruilin Huang Yulong Yin 2020Science China(Life Sciences)2020,63,6:10
2Diurnal variations of the planetary boundary layer height estimated from intensive radiosonde observations over Yichang, China显示文摘By using the eight-times-daily sampling data from an intensive radiosonde observation campaign at Yichang(111°18′E,30°42′N),China in August 2006 and January 2007,the diurnal variation of the planetary boundary layer height determined by using a bulk Richardson(Ri)number approach,was studied in this paper.It was found that the boundary layer heights in both summer and winter months showed diurnal changes and the daily cycle was deeper in summer,which agreed well with the previous studies;the monthly averaged height was 103–1112 m and 89–450 m in summer and winter,respectively;the morning rise began at 0700 LT/1000 LT in summer/winter and the evening transition occurred at 1900 LT in both seasons;the maximum height occurred in the afternoon for most cases,except some peaks found in the winter night;the surface temperature and relative humidity dominated the variations of summer height,while the diurnal variation shown in January 2007 might have some connections with the dynamical processes in the lower troposphere,besides the surface effects.ZHANG YeHui ZHANG ShaoDong HUANG ChunMing HUANG KaiMing GONG Yun GAN Quan 2014Science China(Technological Sciences)2014,57,11:7
3Heat Treatment Effect on Microstructure, Hardness and Wear Resistance of Cr26 White Cast Iron显示文摘High chromium cast iron(HCCI) is taken as material of coal water slurry pump impeller, but it is susceptible to produce serious abrasive wear and erosion wear because of souring of hard coal particles. The research on optimization of heat treatments to improve abrasive wear properties of HCCI is insufficient, so effect of heat treatments on the microstructure, hardness, toughness, and wear resistance of Cr26 HCCI is investigated to determine the optimal heat treatment process for HCCI. A series of heat treatments are employed. The microstructures of HCCI specimens are examined by using optical microscopy and scanning electron microscopy. The hardness and impact fracture toughness of as-cast and heat treated specimens are measured. The wear tests are assessed by a Type M200 ring-on block wear tester. The results show the following: With increase of the quenching temperature from 950 ℃ to 1050 ℃, the hardness of Cr26 HCCI increased to a certain value, kept for a time and then decreased. The optimal heat treatment process is 2 h quenching treatment at 1000 ℃, followed by a subsequent 2 h tempering at 400 ℃. The hardness of HCCI is related to the precipitation and redissolution of secondary carbides in the process of heat treatment. The subsequent tempering treatment would result in a slight decrease of hardness but increase of toughness. The wear resistance is much related to the 'supporting' effect of the matrix and the 'protective' effect of the hard carbide embedded in the matrix, and the wear resistance is further dependent on the hardness and the toughness of the matrix. This research can provide an important insight on developing an optimized heat treatment method to improve the wear resistance of HCCI.ZHOU Shaoping SHEN Yehui ZHANG Hao CHEN Dequan 2015Chinese Journal of Mechanical Engineering2015,28,1:7
4Benefit of everolimus as a monotherapy for a refractory breast cancer patient bearing multiple genetic mutations in the PI3K/AKT/mTOR signaling pathway显示文摘A postmenopausal patient with a diagnosis of estrogen receptor(ER)(+), progesterone receptor(PR)(+), and human epidermal growth factor receptor-2(HER2)(-) breast cancer was reported. The patient refused surgery and was resistant to conventional chemotherapy regimens. Computed tomography and the circulating tumor cell test indicated that the patient's tumor burden increased rapidly even after several chemotherapy sessions. Multiple genetic aberrances in the phosphatidylinositol3-kinases(PI3 K) signaling pathway were detected via next-generation sequencing(NGS)-based liquid biopsy, including a p. G1007 R missense mutation in exon 21 of PIK3 CA(33.61%), a p.L70 fs frameshift mutation in exon 3 of phosphatase and tension homolog deleted on chromosome ten(PTEN)(49.14%), and a p. D1542 Y missense mutation in exon 32 of mammalian target of rapamycin(m TOR)(1.66%). Therefore, only the m TOR inhibitor everolimus was administered to the patient. Partial remission(PR) was observed after 2 months, and sustained stable disease(SD) was observed after a year and a half. Subsequent sequencing showed that the mutation ratio of PIK3 CA decreased to 4.17%, and that the PTEN and m TOR mutations disappeared, which revealed the significant curative effect of everolimus. We report the first case of successful monotherapy treatment using everolimus in a patient with advanced breast cancer bearing mutations in genes involved in the PI3 K/ARK/m TOR signaling pathway. The success of this case highlights the invaluable clinical contribution of NGS-based liquid biopsy, as it successfully provided an optimal therapeutic target for the patient with advanced breast cancer.Yehui Shi Wenwen Zhang Yingnan Ye Yanan Cheng Lei Han Pengpeng Liu Weipeng Zhao Zhongsheng Tong Jinpu Yu 2018Cancer Biology & Medicine2018,15,3:6

6Protective effects of taurine against muscle damage induced by diquat in 35 days weaned piglets显示文摘Background: Oxidative stress is a key factor that influences piglets' health. Taurine plays an imperative role in keeping the biological system from damage. This study was conducted to investigate the protective effect of taurine against muscle injury due to the secondary effect of diquat toxicity.Results: Our study found that taurine effectively and dose-dependently alleviated the diquat toxicity induced rise of feed/gain, with a concurrent improvement of carcass lean percentage. The plasma content of taurine was considerably increased in a dose-dependent manner. Consequently, dietary taurine efficiently improved the activity of plasma antioxidant enzymes. Furthermore, taurine attenuated muscle damage by restoring mitochondrial micromorphology, suppressing protein degradation and reducing the percentage of apoptotic cells in the skeletal muscle. Taurine supplementation also suppressed the genes expression levels of the antioxidant-, mitochondrial biogenesis-, and muscle atrophy-related genes in the skeletal muscle of piglets with oxidative stress.Conclusions: These results showed that the dose of 0.60% taurine supplementation in the diet could attenuate skeletal muscle injury induced by diquat toxicity. It is suggested that taurine could be a potential nutritional intervention strategy to improve growth performance.Chaoyue Wen Fengna Li Qiuping Guo Lingyu Zhang Yehui Duan Wenlong Wang Jianzhong Li Shanping He Wen Chen Yulong Yin 2020Journal of Animal Science and Biotechnology2020,11,4:5
7Chemometric study of spatial variations of environmental and ecological characteristics in the Zhujiang River (Pearl River) Estuary and adjacent waters显示文摘Chemometric approach based on principal component analysis(PCA) was utilized to examine the spatial variances of environmental and ecological characteristics in the Zhujiang River(Pearl River) Estuary and adjacent waters(ZREAW) in the South China Sea. The PCA result shows that the ZREAW can be divided into different zones according to the principal components and geographical locations of the study stations,and indicates that there are distinct regional variances on environmental features and the corresponding phytoplankton biomass and community structures among different areas. The spatial distribution of ecological features was implied to be influenced by various degrees of the different water resources,such as the Pearl River discharges,the coastal current and the oceanic water from the South China Sea. The variation of the biomass maximum zone and the complex impacts on the spatial distributions of phytoplankton biomass and production were also evaluated.SONG Xingyu HUANG Liangmin ZHANG Jianlin YIN Kedong LIU Sheng TAN Yehui YIN Jianqiang 2011Acta Oceanologica Sinica2011,30,4:5
8PhaseⅠdose-escalation and expansion study of PARP inhibitor,fluzoparib(SHR3162),in patients with advanced solid tumors显示文摘Objective:Fluzoparib(SHR3162)is a novel,potent poly(ADP-ribose)polymerases(PARP)1,2 inhibitor that showed anti-tumor activity in xenograft models.We conducted a phaseⅠ,first-in-human,dose-escalation and expansion(D-Esc and D-Ex)trial in patients with advanced solid cancer.Methods:This was a 3+3 phaseⅠD-Esc trial with a 3-level D-Ex at 5 hospitals in China.Eligible patients for DEsc had advanced solid tumors refractory to standard therapies,and D-Ex enrolled patients with ovarian cancer(OC).Fluzoparib was administered orally once or twice daily(bid)at 11 dose levels from 10 to 400 mg/d.Endpoints included dose-finding,safety,pharmacokinetics,and antitumor activity.Results:Seventy-nine patients were enrolled from March,2015 to January,2018[OC(47,59.5%);breast cancer(BC)(16,20.3%);colorectal cancer(8,10.1%),other tumors(8,10.1%)];48 patients were treated in the D-Esc arm and 31 in the D-Ex arm.The maximum tolerated dose(MTD)was 150 mg bid,with a half-life of 9.14 h.Grade 3/4 adverse events included anemia(7.6%)and neutropenia(5.1%).The objective response rate(ORR)was 30%(3/10)in patients with platinum-sensitive OC and 7.7%(1/13)in patients with BC.Among patients treated with fluzoparib≥120 mg/d,median progression-free survival(m PFS)was 7.2[95%confidence interval(95%CI),1.8-9.3]months in OC,9.3(95%CI,7.2-9.3)months in platinum-sensitive OC,and 3.5(range,2.0-28.0)months in BC.In patients with germline BC susceptibility gene mutation(g BRCAMut)(11/43 OC;2/16 BC),m PFS was 8.9 months for OC(range,1.0-23.2;95%CI,1.0-16.8)and 14 and 28 months for BC(those two patients both also had somatic BRCAMut).Conclusions:The MTD of fluzoparib was 150 mg bid in advanced solid malignancies.Fluzoparib demonstrated single-agent antitumor activity in BC and OC,particularly in BRCAMut and platinum-sensitive OC.Huiping Li Rongrui Liu Bin Shao Ran Ran Guohong Song Ke Wang Yehui Shi Jihong Liu Wenjing Hu Fu Chen Xiaoran Liu Gairong Zhang Chuanhua Zhao Ru Jia Quanren Wang Hope S.Rugo Yifan Zhang Guangze Li Jianming Xu 2020Chinese Journal of Cancer Research2020,32,3:4
9Relationship between phytoplankton composition and environmental factors in the surface waters of southern South China Sea in early summer of 2009显示文摘Horizontal distributions of phytoplankton abundance,species composition as well as environmental factors were investigated in the surface waters of southern South China Sea(SCS) in early summer(May 16 to June 7) of 2009.In most areas of southern SCS,the concentrations of nitrogen and phosphorus were very low and DIN/DIP ratios usually were lower than the Redfield N/P Ratio of 16:1.Nitrogen nutrients were significant lower in the upwelling region off Vietnam.A total of 144 taxa of phytoplankton were identified in the study area.The dominant genera were Prorocentrum,Gonyaulax,Gyrodinium,Scrippsiella and Chaetoceros,respectively.Spatial patterns of early-summer phytoplankton abundance and species composition should be mainly controlled by the upwelling off Vietnam and the discharge of Mekong River in the southern SCS.Diatoms dominated in the nutritious Mekong River Estuary or upwelling region off Vietnam;while dinoflagellates dominated in the oligotrophic pelagic region.The canonical correspondence analysis(CCA) indicates that most of diatoms favor higher levels of silicate and phosphorus,as well as lower temperature;while most of dinoflagellates favor the lower silicate and phosphorous and higher temperature.Correlation and CCA results indicate that silicate,nitrate and temperature were the most relevant environmental factors to regulate the horizontal pattern of early-summer phytoplankton in the surface waters of southern SCS.KE Zhixin TAN Yehui HUANG Liangmin ZHANG Jianlin LIAN Shumin 2012Acta Oceanologica Sinica2012,31,3:3
10Comparisons of carcass traits,meat quality,and serum metabolome between Shaziling and Yorkshire pigs显示文摘This study aims to compare the meat quality of Shaziling and Yorkshire pigs and to find the potential indicator in serum for superior meat quality.Six Shaziling and Yorkshire pigs at 30,60,90,150,210,and 300 d of age were selected to examine carcass traits,meat quality,and serum metabolome.The results showed that the body weight,carcass length,and loin eye area of Shaziling pigs at 150,210,and 300 d of age were significantly lower than those of Yorkshire pigs(P<0.05).Shaziling pigs at 150 and 300 d of age had significantly lower backfat thickness than Yorkshire pigs(P<0.05).Compared with Yorkshire pigs,Shaziling pigs at all 6 ages had a lower lean percentage and a higher fat percentage(P<0.05).At 60,90,and 150 d of age,the post-mortem pH-decline,b*value(yellowness),and drip loss of Shaziling pigs were significantly lower than those of Yorkshire pigs(P<0.05).Moreover,at 150 d of age,Shaziling pigs had significantly higher a^(*)value(redness)and intramuscular fat(IMF)content than Yorkshire pigs(P<0.05).Correlation analysis between the top 40 metabolites and phenotypes indicated that L-carnitine had positive correlations with fat percentage,pH24h,and IMF content,but had negative correlations with lean percentage,L^(*)value(lightness),and b^(*)value(P<0.05).Serum L-carnitine content,fat percentage,pH24h,and IMF content all decreased first and then increased as the pigs grew,which verified the positive correlations between L-carnitine and these phenotypes.In conclusion,Shaziling pigs have a slower growth rate but a better meat quality than Yorkshire pigs.The meat quality of Shaziling pigs is the best from 150 to 210 d of age.This study suggests that a higher serum L-carnitine content is a promising indicator for better meat quality.Bo Song Changbing Zheng Jie Zheng Shiyu Zhang Yinzhao Zhong Qiuping Guo Fengna Li Cimin Long Kang Xu Yehui Duan Yulong Yin 2022Animal Nutrition2022,,1:3
11The ANIP1-OsWRKY62 module regulates both basal defense and Pi9-mediated immunity against Magnaporthe oryzae in rice显示文摘During effector-triggered immunity(ETI)against the devastating rice blast pathogen Magnaporthe oryzae,Pi9 functions as an intracellular resistance protein sensing the pathogen-secreted effector AvrPi9 in rice.Importantly,the underlying recognition mechanism(s)between Pi9 and AvrPi9 remains elusive.In this study,We identified a rice ubiquitin-like domain-containing protein(UDP),AVRPI9-INTERACTING PROTEIN 1(ANP1),which is directly targeted by AvrPi9 and also binds to Pi9 in plants.Phenotypic analysis of anip1 mu-tants and plants overexpressing ANIP1 revealed that ANIP1 negatively modulates rice basal defense against M.oryzae.ANiP1 undergoes 26S proteasome-mediated degradation,which can be blocked by both AvrPi9 and Pi9.Moreover,ANIP1 physically associates with the rice WRKY transcription factor OsWRKY62,which also interacts with AvrPi9 and Pi9 in plants.In the absence of Pi9,ANIP1 negatively regulates OsWRKY62 abundance,which can be promoted by AvrPi9.Accordingly,knocking out of OsWRKY62 in a non-Pi9 back-ground decreased immunity against M.oryzae.However,we also observed that OsWRKY62 plays negative roles in defense against a compatible M.oryzae strain in Pi9-harboring rice.Pi9 binds to ANiP1 and OsWRKY62 to form a complex,which may help to keep Pi9 in an inactive state and weaken rice immunity.Furthermore,using competitive binding assays,we showed that AvrPi9 promotes Pi9 dissociation from ANiP1,which could be an important step toward ETI activation.Taken together,our results reveal an immune strategy whereby a UDP-WRKY module,targeted by a fungal effector,modulates rice immunity in distinct ways in the presence or absence of the corresponding resistance protein.Xuetao Shi Yehui Xiong Kai Zhang Yinshan Zhang Junqi Zhang Lili Zhang Yutao Xiao Guo-Liang Wang Wende Liu 2023Molecular Plant2023,16,4:3
12Diurnal variability of the planetary boundary layer height estimated from radiosonde data显示文摘Diurnal variations in the planetary boundary layer height(PBLH)at different latitudes over different surface characteristics are described,based on 45 years(1973−2017)of radiosonde observations.The PBLH is determined from the radiosonde data by the bulk Richardson number(BRN)method and verified by the parcel method and the potential temperature gradient method.In general,the BRN method is able to represent the height of the convective boundary layer(BL)and neutral residual layer cases but has relatively large uncertainty in the stable BL cases.The diurnal cycle of the PBLH over land is quite different from the cycle over ocean,as are their seasonal variations.For stations over land,the PBLH shows an apparent diurnal cycle,with a distinct maximum around 15:00 LT,and seasonal variation,with higher values in summer.Compared with the PBLH over land,over oceans the PBLH diurnal cycles are quite mild,the PBLHs are much lower,and the seasonal changes are less pronounced.The seasonal variations in the median PBLH diurnal cycle are positively correlated with the near-surface temperature and negatively correlated with the near-surface relative humidity.Finally,although at most latitudes the daytime PBLH exhibits,over these 45 years,a statistically significant increasing trend at most hours between 12:00 LT and 18:00 LT over both land and ocean,there is no significant trend over either land or ocean in the nighttime PBLH for almost all the studied latitudes.Jie Gu YeHui Zhang Na Yang Rui Wang 2020Earth and Planetary Physics2020,4,5:2

14Dynamic structure change of Cu nanoparticles on carbon supports for CO_(2) electro-reduction toward multicarbon products显示文摘Cu nanoparticles with different sizes,morphology,and surface structures exhibit distinct activity and selectivity toward CO_(2) reduction reaction,while the reactive sites and reaction mechanisms are very controversial in experiments.In this study,we demonstrate the dynamic structure change of Cu clusters on graphite-like carbon supports plays an important role in the multicarbon production by combining static calculations and ab-initio molecular dynamic simulations.The mobility of Cu clusters on graphite is attributed to the near-degenerate energies of various adsorption configurations,as the interaction between Cu atoms and surface C atoms is weaker than that of Cu-Cu bonds in the tight cluster form.Such structure change of Cu clusters leads to step-like irregular surface structures and appropriate interparticle distances,increasing the selectivity of multicarbon products by reducing the energy barriers of C-C coupling effectively.In contrast,the large ratio of edge and corner sites on Cu clusters is responsible for the increased catalytic activity and selectivity for CO and H_(2) compared with Cu(100)surface,instead of hydrocarbon products like methane and ethylene.The detailed study reveals that the dynamic structure change of the catalysts results in roughened surface morphologies during catalytic reactions and plays an essential role in the selectivity of CO_(2) electro-reduction,which should be paid more attention for studies on the reaction mechanisms.Qiang Li Yehui Zhang Li Shi Mingliang Wu Yixin Ouyang Jinlan Wang 2021InfoMat2021,3,11:1
15Helical Poly(α,β-unsaturated ketone)with Bulky Pendant of Binaphthyl from Anionic Polymerization of(−)-Menthyl(S)-6'-Acrylyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate显示文摘(−)-Menthyl(S)-6'-acrylyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate(3)was synthesized and anionically polymerized using n-BuLi as an initiator in toluene.The monomer 3 was levorotatory and had an[α]_(D)^(25)value of−72.4,but its corresponding polymer poly-3 was dextrorotatory and showed an[α]_(D)^(25)value of+162.0.Poly-3 was confirmed to exist in the form of one-handed helical structure in solution by means of comparing the specific optical rotation and the CD spectra with that of 3 and the model compounds such as(−)-menthyl(S)-6'-propionyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate 2b and(−)-menthyl(S)-6'-heptanoyl-2'-methyloxy-1,1'-binaphthalene-2-carboxylate 2c.This conclusion was also confirmed by the fact that the g-value of poly-3 is about 11 times of that of monomer 3.Yehui Chen Liwen Yang Nianfa Yang Zhusheng Yang Jin Zhang 2014Chinese Journal of Chemistry2014,32,3:1
16Shen Qi Wan attenuates renal interstitial fibrosis through upregulating AQP1显示文摘Renal interstitial fibrosis(RIF)is the crucial pathway in chronic kidney disease(CKD)leading to the end-stage renal failure.However,the underlying mechanism of Shen Qi Wan(SQW)on RIF is not fully understood.In the current study,we investigated the role of Aquaporin 1(AQP1)in SQW on tubular epithelial-to-mesenchymal transition(EMT).A RIF mouse model induced by adenine and a TGF-β1-stimulated HK-2 cell model were etablished to explore the involvement of AQP 1 in the protective effect of SQW on EMT in vitro and in vivo.Subsequently,the molecular mechanism of SQW on EMT was explored in HK-2 cells with AQP1 knockdown.The results indicated that SQW alleviated kidney injury and renal collagen deposition in the kidneys of mice induced by adenine,increased the protein expression of E-cadherin and AQP1 expression,and decreased the expression of vimentin andα-smooth muscle actin(α-SMA).Similarly,treatmement with SQW-containing serum significantly halted EMT process in TGF-β1 stimulated HK-2 cells.The expression of snail and slug was significantly upregulated in HK-2 cells after knockdown of AQP1.AQP1 knockdown also increased the mRNA expression of vimentin andα-SMA,and decreased the expression of E-cadherin.The protein expression of vimentin increased,while the expression of E-cadherin and CK-18 significantly decreased after AQP1 knockdown in HK-2 cells.These results revealed that AQP1 knockdown promoted EMT.Furthermore,AQP1 knockdown abolished the protective effect of SQW-containing serum on EMT in HK-2 cells.In sum,SQW attentuates EMT process in RIF through upregulation of the expression of AQP1.LIN Yiyou WEI Jiale ZHANG Yehui HUANG Junhao WANG Sichen LUO Qihan YU Hongxia JI Liting ZHOU Xiaojie LI Changyu 2023Chinese Journal of Natural Medicines2023,21,5:1
17基于无线电掩星数据,探空资料以及再分析资料估算大气边界层高度的比较显示文摘用11年的全球无线电掩星数据(COSMIC),无线电探空数据(IGRA)以及欧洲中心再分析资料(ERA-Interim)对全球大气边界层高度(PBLH)进行估算比较.结果表明:(1)在1200 UTC和0000 UTC,由ERA-Interim和IGRA数据估算得到的全球PBLH空间分布较为一致,相关性较好,在白天正午时候太阳辐射能力较强,对流活动频繁,估算得到的大气边界层高度较高.(2)由COSMIC掩星数据估算得到的边界层高度比探空数据和再分析数据估算结果整体偏大.(3)COSMIC掩星数据,IGRA探空数据以及ERA-Interim再分析资料估算结果都表明边界层高度在低纬度地区偏大,高纬度地区偏小.(4)分析不同数据估算边界层高度纬向季节性差异表明,IGRA探空数据和COSMIC数据间差异为-1700m至-500m,IGRA与ERA-Interim之间的差异为-500m至250m.此外,对于大多数纬度而言,三个数据集之间的差异在冬季较大,在夏季较小.Jie Gu Yehui Zhang Na Yang Rui Wang 2021Atmospheric and Oceanic Science Letters2021,14,2:1
18Shen-Qi-Wan Protects the Renal Peritubular Capillary Injury from Adenine-mediated Damage by Upregulating Aquaporin 1显示文摘Background:Shen-Qi-Wan(SQW),a commonly used prescription against chronic kidney disease(CKD)in Tradi-tional Chinese Medicine(TCM),has a nephroprotective action in adenine-induced kidney injury.However,the mechanism of SQW in renal injury remains unclear.Objective:This study was undertaken to measure the effect of SQW on peritubular capillary injury both in vivo and in vitro assays.Methods:The effect of SQW on the peritubular capillary injury was evaluated according to measuring hypothalamic-pituitary-adrenal(HPA)function,inflammatory cytokines,VEGF(vascular endothelial growth fac-tor),CD34(Cluster of differentiation 34),and AQP1(Aquaporin 1)levels in the kidney,cell migration,and lumen forming capacity.Results:SQW supplementation could ameliorate dysfunction of the HPA and renal function loss induced by adenine.SQW also significantly inhibited the inflammatory cytokines including MCP-1(monocyte chemotactic protein-1)and VCAM-1(vascular cell adhesion molecule-1)level.Alternatively,SQW administration showed an ameliorating effect from the toxicity and alleviated the injury of capillaries around renal tubules instigated by adenine through increasing AQP1 mRNA and protein level.SQW medicated the serum enhanced the migration and lumen formation ability of HMEC-1 cells,and significantly increased AQP1 protein level.Moreover,AQP1 knockdown efficiently inhibited the migration and lumen formation ability in HMEC-1 cells,and weakened the effect of SQW medicated serum.Conclusion:These results suggested that SQW attenuated peritubular capillary injury in adenine-induced CKD model rats through boosting angiogenesis in endothelial cell,and AQP1 may be a potential target of SQW for treating the renal injury.Yuting Bao Yehui Zhang Yuanxiao Yang Xueming Chen Luning Lin Yunbo Fu Liting Ji Changyu Li 2022Clinical Complementary Medicine and Pharmacology2022,2,1:1
