1Review of gallium-oxide-based solar-blind ultraviolet photodetectors显示文摘Solar-blind photodetectors are of great interest to a wide range of industrial, civil, environmental, and biological applications. As one of the emerging ultrawide-bandgap semiconductors, gallium oxide(Ga_2O_3) exhibits unique advantages over other wide-bandgap semiconductors, especially in developing high-performance solar-blind photodetectors. This paper comprehensively reviews the latest progresses of solar-blind photodetectors based on Ga_2O_3 materials in various forms of bulk single crystal, epitaxial films, nanostructures, and their ternary alloys.The basic working principles of photodetectors and the fundamental properties and synthesis of Ga_2O_3, as well as device processing developments, have been briefly summarized. A special focus is to address the physical mechanism for commonly observed huge photoconductive gains. Benefitting from the rapid development in material epitaxy and device processes, Ga_2O_3-based solar-blind detectors represent to date one of the most prospective solutions for UV detection technology towards versatile applications.XUANHU CHEN FANGFANG REN SHULIN GU JIANDONG YE 2019Photonics Research2019,7,4:22

3Early Serum HBsAg Kinetics as Predictor of HBsAg Loss in Patients with HBeAg-Negative Chronic Hepatitis B after Treatment with Pegylated Interferonα-2a显示文摘Hepatitis B surface antigen(HBsAg)loss is an ideal treatment endpoint for patients with chronic hepatitis B(CHB).We investigated the predictive value of on-treatment HBsAg levels for HBsAg loss in hepatitis B e antigen(HBe Ag)-negative CHB patients who received 120-week PEG-IFNα-2a treatment.Serum HBV DNA,HBsAg,and anti-HBs levels were assayed at baseline and every 3 months during the treatment.Of 81 patients,12 achieved HBsAg loss,20 achieved HBsAg\100 IU/mL,and 49 maintained HBs Ag C 100 IU/mL.HBsAg loss rate was only 3.7%at 48 weeks,while it reached to 11.1%and 14.8%after treatment of 96 weeks and 120 weeks.The cutoff HBs Ag levels at 12 weeks predicting HBsAg loss at 96 weeks and 120 weeks of treatment were 400 IU/mL and 750 IU/mL,with AUC 0.725 and 0.722,positive predictive value(PPV)29.41%and 30.56%,and negative predictive value(NPV)93.75%and 97.78%,respectively.The cutoff HBsAg levels at 24 weeks predicting HBsAg loss at 96 weeks and 120 weeks of treatment were 174 IU/m L and 236 IU/mL respectively,with AUC 0.925 and 0.922,PPV 40.0%and 46.15%,and both NPV 100%.The predictive ability of the cutoff HBsAg levels at 24 weeks was better than that at 12 weeks for HBs Ag loss at either 96 or 120 weeks(χ~2=3.880,P=0.049 andχ~2=4.412,P=0.036).These results indicate that extended therapy is critical to HBsAg loss in HBe Ag-negative CHB patients during PEG-IFN treatment,and the HBsAg level at 24 weeks can be used to predict HBsAg loss during tailoring PEG-IFN therapy.Minghui Li Lu Zhang Yao Lu Qiqi Chen Huihui Lu Fangfang Sun Zhan Zeng Gang Wan Linqing Zhao Yao Xie 2021Virologica Sinica2021,36,2:15
4Epidemic Update and Risk Assessment of 2019 Novel Coronavirus--China, January 28, 2020显示文摘On December 29,2019,the health authorities in Hubei Province and Wuhan City received a report of a cluster of pneumonia cases of unknown etiology from a local hospital,and all four patients were employees of the Wuhan Huanan Seafood Wholesale Market(HN market for short)(1).By January 8,2020,Chinese authorities had identified a new virus 2019 novel coronavirus(2019-nCoV)linked with the outbreak of disease,which has been named novel coronavirusinfected pneumonia(NCIP)(2).On 15 January,the National Health Commission(NHC)issued guidelines for the diagnosis,treatment,prevention,and control of NCIP.These guidelines directed case monitoring,reporting,diagnosis,treatment,management,close contact management,and laboratory testing.Wenxiao Tu Houlin Tang Fangfang Chen Yinong Wei Tingling Xu Kaiju Liao Nijian Xiang Guoqing Shi Qun Li Zijian Feng 2020China CDC weekly2020,2,6:15
5Crop 3D a LiDAR based platform for 3D high-throughput crop phenotyping显示文摘With the growing population and the reducing arable land, breeding has been considered as an effective way to solve the food crisis.As an important part in breeding, high-throughput phenotyping can accelerate the breeding process effectively. Light detection and ranging(LiDAR) is an active remote sensing technology that is capable of acquiring three-dimensional(3 D) data accurately,and has a great potential in crop phenotyping. Given that crop phenotyping based on LiDAR technology is not common in China,we developed a high-throughput crop phenotyping platform, named Crop 3 D, which integrated LiDAR sensor, high-resolution camera, thermal camera and hyperspectral imager. Compared with traditional crop phenotyping techniques, Crop 3 D can acquire multi-source phenotypic data in the whole crop growing period and extract plant height, plant width, leaf length, leaf width, leaf area, leaf inclination angle and other parameters for plant biology and genomics analysis. In this paper, we described the designs,functions and testing results of the Crop 3 D platform, and briefly discussed the potential applications and future development of the platform in phenotyping. We concluded that platforms integrating LiDAR and traditional remote sensing techniques might be the future trend of crop high-throughput phenotyping.Qinghua Guo Fangfang Wu Shuxin Pang Xiaoqian Zhao Linhai Chen Jin Liu Baolin Xue Guangcai Xu Le Li Haichun Jing Chengcai Chu 2018Science China(Life Sciences)2018,61,3:14
6Ferroptosis in cancer and cancer immunotherapy显示文摘The hallmark of tumorigenesis is the successful circumvention of cell death regulation for achieving unlimited replication and immortality.Ferroptosis is a newly identified type of cell death dependent on lipid peroxidation which differs from classical programmed cell death in terms of morphology,physiology and biochemistry.The broad spectrum of injury and tumor tolerance are the main reasons for radiotherapy and chemotherapy failure.The effective rate of tumor immunotherapy as a new treatment method is less than 30%.Ferroptosis can be seen in radiotherapy,chemotherapy,and tumor immunotherapy;therefore,fer-roptosis activation may be a potential strategy to overcome the drug resistance mechanism of traditional cancer treatments.In this review,the characteristics and causes of cell death by lipid peroxidation in ferroptosis are briefly described.In addition,the three metabolic regulations of ferroptosis and its crosstalk with classical signaling pathways are summarized.Collectively,these findings sug-gest the vital role of ferroptosis in immunotherapy based on the interaction of ferroptosis with tumor immunotherapy,chemotherapy and radiotherapy,thus,indicating the remarkable potential of ferroptosis in cancer treatment.Lei Zhao Xiaoxue Zhou Feng Xie Lei Zhang Haiyan Yan Jun Huang Chong Zhang Fangfang Zhou Jun Chen Long Zhang 2022Cancer Communications2022,42,2:10
7Expression Analysis of miRNAs and Highly-expressed Small RNAs in Two Rice Subspecies and their Reciprocal Hybrids显示文摘Heterosis,or hybrid vigor,is the phenomenon whereby progeny of two inbred lines exhibit superior agronomic performance compared with either parent.We analyzed the expression of miRNAs and highly expressed small RNAs (defined according to Solexa sequencing results) in two rice (Oryza sativa) subspecies (japonica cv.Nipponbare and indica cv.93-11) and their reciprocal hybrids using microarrays.We found that of all the 1141 small RNAs tested,140 (12%,140 of 1141) and 157 (13%,157 of 1141) were identified being significantly differentially expressed in two reciprocal hybrids,respectively.All possible modes of action,including additive,high-and low-parent,above high-and below low-parent modes were exhibited.Both F1 hybrids showed non-additive expression patterns,with downregulation predominating.Interestingly,15 miRNAs displayed stark opposite expression trends relative to midparent in reciprocal hybrids.Computational prediction of targets of differentially expressed miRNAs showed that they participated in multifaceted developmental pathways,and were not distinguishable from the targets of non-differentially expressed miRNAs.Together,our findings reveal that small RNAs play roles in heterosis and add a new layer in the understanding and exploitation of molecular mechanisms of heterosis.Fangfang Chen Guangming He Hang He Wei Chen Xiaopeng Zhu Manzhong Liang Liangbi Chen Xing Wang Deng 2010Journal of Integrative Plant Biology2010,52,11:10
8Variation in cis-regulation of a NAC transcription factor contributes to drought tolerance in wheat显示文摘Drought is a major environmental factor limiting wheat production worldwide,and developing drought-tolerant cultivars is a central challenge for wheat breeders globally.Therefore,it is important to identify genetic components determining drought tolerance in wheat.In this study,we identified a wheat NAC gene(TaNAC071-A)that is tightly associated with drought tolerance by a genome-wide association study.Knockdown of TaNAC071-A in wheat attenuated plant drought tolerance,whereas its overexpression significantly enhanced drought tolerance through improved water-use efficiency and increased expression of stress-responsive genes.This heightened water-saving mechanism mitigated the yield loss caused by water deficit.Further candidate gene association analysis showed that a 108-bp insertion in the promoter of TaNAC071-A alters its expression level and contributes to variation in drought tolerance among wheat accessions.This insertion contains two MYB cis-regulatory elements(CREs)that can be directly bound by the MYB transcription activator,TaMYBL1,thereby leading to increased TaNAC071-A expression and plant drought tolerance.Importantly,introgression of this 108-bp insertion allele,TaNAC071-AIn-693,into drought-sensitive cultivars could improve their drought tolerance,demonstrating that it is a valuable genetic resource for wheat breeding.Taken together,our findings highlight a major breakthrough in determining the genetic basis underlying phenotypic variation in wheat drought tolerance and showcase the potential of exploiting CRE-containing indels for improving important agronomical traits.Hude Mao Shumin Li Bin Chen Chao Jian Fangming Mei Yifang Zhang Fangfang Li Nan Chen Tian Li Linying Du Li Ding Zhongxue Wang Xinxiu Cheng Xiaojing Wang Zhensheng Kang 2022Molecular Plant2022,15,2:9
9A Filtering Approach Based on MMAE for a SINS/CNS Integrated Navigation System显示文摘This paper explores multiple model adaptive estimation(MMAE) method, and with it, proposes a novel filtering algorithm. The proposed algorithm is an improved Kalman filter— multiple model adaptive estimation unscented Kalman filter(MMAE-UKF) rather than conventional Kalman filter methods,like the extended Kalman filter(EKF) and the unscented Kalman filter(UKF). UKF is used as a subfilter to obtain the system state estimate in the MMAE method. Single model filter has poor adaptability with uncertain or unknown system parameters,which the improved filtering method can overcome. Meanwhile,this algorithm is used for integrated navigation system of strapdown inertial navigation system(SINS) and celestial navigation system(CNS) by a ballistic missile's motion. The simulation results indicate that the proposed filtering algorithm has better navigation precision, can achieve optimal estimation of system state, and can be more flexible at the cost of increased computational burden.Fangfang Zhao Cuiqiao Chen Wei He Shuzhi Sam Ge 2018IEEE/CAA Journal of Automatica Sinica2018,5,6:8
10Circulating tumor cells:biology and clinical significance显示文摘Circulating tumor cells(CTCs)are tumor cells that have sloughed off the primary tumor and extravasate into and circulate in the blood.Understanding of the metastatic cascade of CTCs has tremendous potential for the identification of targets against cancer metastasis.Detecting these very rare CTCs among the massive blood cells is challenging.However,emerging technologies for CTCs detection have profoundly contributed to deepening investigation into the biology of CTCs and have facilitated their clinical application.Current technologies for the detection of CTCs are summarized herein,together with their advantages and disadvantages.The detection of CTCs is usually dependent on molecular markers,with the epithelial cell adhesion molecule being the most widely used,although molecular markers vary between different types of cancer.Properties associated with epithelial-tomesenchymal transition and stemness have been identified in CTCs,indicating their increased metastatic capacity.Only a small proportion of CTCs can survive and eventually initiate metastases,suggesting that an interaction and modulation between CTCs and the hostile blood microenvironment is essential for CTC metastasis.Single-cell sequencing of CTCs has been extensively investigated,and has enabled researchers to reveal the genome and transcriptome of CTCs.Herein,we also review the clinical applications of CTCs,especially for monitoring response to cancer treatment and in evaluating prognosis.Hence,CTCs have and will continue to contribute to providing significant insights into metastatic processes and will open new avenues for useful clinical applications.Danfeng Lin Lesang Shen Meng Luo Kun Zhang Jinfan Li Qi Yang Fangfang Zhu Dan Zhou Shu Zheng Yiding Chen Jiaojiao Zhou 2021Signal Transduction and Targeted Therapy2021,6,12:8

12sLe^(x) expression in invasive micropapillary breast carcinoma is associated with poor prognosis and can be combined with MUC1/EMA as a supplementary diagnostic indicator显示文摘Objective: Mucin 1(MUC1/EMA) and sialyl Lewis X(sLe^(x)) indicate polarity reversal in invasive micropapillary carcinoma(IMPC). The purpose of this study was to evaluate the expression of MUC1/EMA and sLe^(x) and to assess their diagnostic and prognostic value in patients with IMPC.Methods: The expression of sLe^(x) and MUC1/EMA in 100 patients with IMPC and a control group of 89 patients with invasive ductal carcinoma not otherwise specified(IDC-NOS) were analyzed with IHC. Fresh tumor tissues were collected from patients with IMPC or IDC-NOS for primary culture and immunofluorescence analysis.Results: The rate of nodal metastasis was higher in patients with IMPC than those with IDC-NOS, and IMPC cells tended to express more sLe^(x) and MUC1/EMA in the cytomembranes(the stroma-facing surfaces of the micropapillary clusters) than IDC-NOS cells. In IMPC, high cytomembrane expression of sLe^(x), but not MUC1/EMA, indicated poor prognosis. In addition, among the 100 patients with IMPC, 10 patients had sLe^(x)+/EMA-expression patterns, and 8 patients had sLe^(x)-/EMA+ expression patterns. The primary IMPC cells were suspended, non-adherent tumor cell clusters, whereas the primary IDC cells were adherent tumor cells. Immunofluorescence analysis showed that MUC1/EMA and sLe^(x) were co-expressed on the cytomembranes in IMPC cell clusters and in the cytoplasm in IDC-NOS cells.Conclusions: sLe^(x) can be used as a prognostic indicator and can be combined with MUC1/EMA as a complementary diagnostic indicator to avoid missed IMPC diagnosis.Yawen Song Hui Sun Kailiang Wu Jianke Lyu Jingyue Zhang Feng Gu Yongjie Ma Beibei Shen Chijuan Wang Xiaojiao Chen Jing Xu Weidong Li Fangfang Liu Li Fu 2021Cancer Biology & Medicine2021,18,2:7
13Phase-transfer synthesis of α-Co(OH)_2 and its conversion to CoO for efficient electrocatalytic water oxidation显示文摘Water splitting is an attractive way to produce recyclable hydrogen energy resource. The oxygen evolution reaction(OER) is the rate-determine step of water electrolysis. The exploring of low-cost, highly efficient and durable electrocatalysts for OER is thus extremely important. In this work, we developed a facile two-phase protocol to fabricate an α-Co(OH)_2 using sodium oleate as the phase-transfer surfactant.The crystallinity and structure of the α-Co(OH)_2 was regulated by heat treatments toward enhanced electrocatalytic OER activity. With the calcination of the as-prepared α-Co(OH)_2 at 200 °C, a networked and well-dispersed CoO nanoparticles were formed. The CoO sample afforded an OER current density of 10 mA cm^(-2) under a low overpotential of 312 mV in a 1 mol L^(-1) KOH aqueous solution. The high activity of the CoO material is believed to be associated with its ultra-small particle size and plentiful open spaces in the material, both of which can provide abundant surface catalytic sites.Dingyi Guo Fangfang Chen Wei Zhang Rui Cao 2017Science Bulletin2017,62,9:6
14Redox processes in subduction zones:Progress and prospect显示文摘Oxygen fugacity(fO_(2))is an intensive variable that describes the redox state of a system.By controlling the valence state of multivalent elements,fO_(2)affects the stability of iron-bearing minerals,dominants the species of volatile elements(e.g.,carbon and sulfur),and controls the partitioning behaviors of multivalent elements(e.g.,iron,vanadium,cerium,europium).Thus,fO_(2)plays a key role in understanding the generation and differentiation of arc magmas,the formation of magmatic-hydrothermal deposits,and the nature of magmatic volatiles.Subduction zones are an important site for arc magmatism and fluid action,and the study of redox processes is indispensable in subduction zone geochemistry.In this paper,we first introduce the concept,expression,and estimation methods of fO_(2).Then we retrospect the history and progress about the oxidation state of the metasomatized mantle wedge,summarize the redox property of slab-derived fluids,and review the latest progress on redox evolution of arc magmas during magma generation and differentiation.The main conclusions include:(1)despite its wide variation range,fO_(2)of the mantle wedge is generally higher than that of the oceanic mantle;(2)the redox property of the subducting slab-derived fluids is still controversial and the mechanism for the oxidization of the mantle wedge remains unclear;(3)how the fO_(2)varies during the generation and differentiation of the arc magmas is debated.We propose that the crux in deciphering the oxidization mechanism of the mantle wedge is to determine the mobility of iron,carbon and sulfur in subducting slab-derived fluids(especially solute-rich fluid or supercritical fluid);the key in understanding the redox evolution during arc magma generation and differentiation is to determine the partition coefficients of Fe^(3+)and Fe^(2+)between ferromagnesian minerals and silicate melts.Jintuan Wang Xiaolin Xiong Yixiang Chen Fangfang Huang 2020Science China Earth Sciences2020,63,12:6
15Aberrant translation regulated by METTL1/WDR4-mediated tRNA N7-methylguanosine modification drives head and neck squamous cell carcinoma progression显示文摘Background:Cancer cells selectively promote the translation of oncogenic tran-scripts to stimulate cancer progression.Although growing evidence has revealed that tRNA modifications and related genes participate in this process,their roles in head and neck squamous cell carcinoma(HNSCC)remain largely unchar-acterized.Here,we sought to investigate the function and mechanisms of the transfer RNA(tRNA)N7-methylguanosine(m'G)modification in regulating the occurrence and development of HNSCC.Methods:Cell lost of-function and gain-of function assays,xenograft models,conditional knockout and knockin mouse models were used to study the physi-ological functions of tRNA m'G modification in HNSCC tumorigenesis.tRNA modification and expression profiling,mRNA translation profiling and res-cue assays were performed to uncover the underlying molecular mechanisms.Single-cell RNA sequencing(scRNA seq)was conducted to explore the tumor microenvironment changes.Results:The tRNA.m7G methyltransferase complex components Methyltransferase-like 1(METTL1)/WD repeat domain 4(WDR4)were upregulated in HNSCC and associated with a poor prognosis.Functionally,METTL1/WDR4 promoted HNSCC progression and metastasis in cell-based and transgenic mouse models.Mechanistically,ablation of METTL1 reduced the m'G levels of 16 tRNAS,inhibiting the translation of a subset of oncogenic transcripts,including genes related to the phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/AKT/mTOR)signaling pathway.In addition,chemical modulators of the PI3K/Akt/mTOR signaling pathway reversed the effects of Mettll in mouse HNSCC.Furthermore,scRNA-seq results revealed that Mettll knockout in mouse tumor cells altered the immune landscape and cell-cell interaction between the tumor and stromal compartment.Conclusions:The tRNA m?G methyltransferase METTLI was found to promote the development and malignancy of HNSCC through regulating global mRNA translation,including the PI3K/AKT/mTOR signaling pathway,and found to alter immune landscape.METTLI could be a promising treatment target for HNSCC patients.Jie Chen Kang Li Jianwen Chen Xiaochen Wang Rongsong Ling Maosheng Cheng Zhi Chen Fangfang Chen Qianting He Shuai Li Caihua Zhang Yizhou Jiang Qianming Chen Anxun Wang Demeng Chen 2022Cancer Communications2022,42,3:6
16MODIS observations of water color of the largest 10 lakes in China between 2000 and 2012显示文摘Forel-Ule(FU)index of water color is an important parameter in traditional water quality investigations.We retrieved the FU index of the largest 10 lakes in China during 2000-2012 from MODerate-resolution Imaging Spectroradiometer surface reflectance product(MOD09)images.Since FU index is an optical parameter,it can be derived from optical remote sensing data by direct formulas,which is invariant with region and season.Based on validation by in situ measured reflectance data,the FU index products are reliable,with average relative error of 7.7%.FU index can be used to roughly assess water clarity:the clearer a water body is,and the bluer it is in color,the smaller its FU index is.FU index can also be used to roughly classify trophic state into three classes:oligotrophic,mesotrophic,and eutrophic.We analyzed the spatial,interannual,and seasonal variations of the FU index and its implications for water clarity and trophic state,and the findings are mostly consistent with the results from related literature.All in all,it might be a feasible way to roughly assess inland water quality by FU index in large region and over long time period.Junsheng Li Shenglei Wang Yanhong Wu Bing Zhang Xiaoling Chen Fangfang Zhang Qian Shen Dailiang Peng Liqiao Tian 2016International Journal of Digital Earth2016,9,8:5
17Activin A maintains cerebral cortex neuronal survival and increases voltage-gated Na^+ neuronal current显示文摘Activin A,which was first described in 1986,has been shown to maintain hippocampal neuronal survival.Activin A increases intracellular free Ca2+ via L-type Ca2+ channels.Our previous study showed that activin A promotes neurite growth of dorsal root ganglia in embryonic chickens and inhibits nitric oxide secretion.The present study demonstrated for the first time that activin A could maintain cerebral cortex neuronal survival in vitro for a long period,and that activin A was shown to increase voltage-gated Na+ current(INa) in Neuro-2a cells,which was recorded by patch clamp technique.The present study revealed a novel mechanism for activin A,as well as the influence of activin A on neurons by regulating expressions of vasoactive intestine peptide and inducible nitric oxide synthase.Jingyan Ge Yinan Wang Haiyan Liu Fangfang Chen Xueling Cui Zhonghui Liu 2010Neural Regeneration Research2010,5,19:4
18Rolling up MXene sheets into scrolls to promote their anode performance in lithium-ion batteries显示文摘Although Ti3 C2 MXene sheets have attracted extensive attention in lithium-ion storage techniques,their restacking makes against and even hinders the Li ions diffusion within them,thereby decreasing the capacity as well as rate performance of conventional MXene anode.Here,for the first time,we roll up the Ti3 C2 Tx sheets into scrolls with unclosed topological structure and the interlayer galleries to alleviate the restacking problem.Thus,Ti3 C2 Tx scrolls as anode materials in lithium-ion batteries(LIBs)have higher capacity and better rate performance than Ti3 C2 Tx sheets.On the bases of these,high-capacity silicon nanoparticles are added during the rolling process to in-situ produce Ti3 C2 Tx/Si composite scrolls.The addition of 10%silicon nanoparticles shows the best overall improvement among capacity,rate capability and cyclic stability for Ti3 C2 Tx scrolls.Jianing Meng Fangfang Zhang Li Zhang Lingyang Liu Jiangtao Chen Bingjun Yang Xingbin Yan 2020Journal of Energy Chemistry2020,29,7:4
19Efficacy of Shoushen granule on adenosine triphosphate binding cassette transporter A1, proprotein convertase subtilisin/kexin type 9 and toll-like receptor 4/nuclear factor kappa-B signaling pathway in ApoE-knockout mice显示文摘OBJECTIVE: To evaluate the efficacy of Shoushen granule, prepared with four Chinese medicinals, on the targeted regulation of adenosine triphosphate binding cassette transporter A1(ABCA1) through proprotein convertase subtilisin/kexin type 9(PCSK9) and toll-like receptor 4(TLR4)/nuclear factor kappa-B(NF-κB) signaling pathway to affect atherosclerosis(AS) in ApoE-knockout(ApoE-/-) mice.METHODS: ApoE-/-mice fed with a high-fat diet were used for AS modeling and divided into Model,Shoushen, and Atorvastatin groups. C57 BL/6 J mice at the same age and background strain were included in the Control group. Western blot and immunohistochemistry were used to measure ABCA1, PCSK9, TLR4, and NF-κB protein expression in mouse aortas. Enzyme-linked immuno sorbent assay was used to measure mouse serum tumor necrosis factor-α(TNF-α), interleukin-10(IL-10), monocyte chemoattractant protein 1(MCP-1), and intercellular cell adhesion molecule-1(ICAM-1) expression. Serum lipid profiles and histopathology were also assessed. Shoushen granule were composed of Heshouwu(Radix Polygoni Multiflori) 15 g, Gouqizi(Fructus Lycii) 15 g, Sheng shanzha(Raw Fructus Crataegus Pinnatifidae) 10 g, and Sanqi(Radix Notoginseng) 3 g.RESULTS: ApoE-/-mice fed with a high-fat diet had notable AS lesions, with reduced ABCA1 and IL-10 levels, elevated PCSK9, TLR4, NF-κB, TNF-α, MCP-1,and ICAM-1 expression, and increased total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) contents. With drug interventions, the areas of AS plaques were significantly reduced,the ABCA1 and IL-10 levels were increase, while the PCSK9, TLR4, NF-κB, TC, and LDL-C contents,and the TNF-α, MCP-1, and ICAM-1 expression were reduced.CONCLUSION: Shoushen granule effectively interfered with AS development by antagonizing the expression of key factors of the PCSK9 and TLR4/NF-κB signaling pathway to upregulate ABCA1 expression.Li Shanshan Cao Hui Shen Dingzhu Chen Chuan Xing Sanli Dou Fangfang Jia Qingling 2019Journal of Traditional Chinese Medicine2019,39,4:4
20Bushen Jiangzhi formula reduces atherosclerosis in apoE-/-mice through autophagy显示文摘OBJECTIVE:To study the effect of Bushen Jiangzhi formula(BSJZF)on atherosclerosis(AS)in apolipoprotein E knockout(apoE^-/-)mice and the underlying mechanism.METHODS:We used a high fat diet to induce AS in apoE^-/- mice.The mice were randomly divided into four groups:model,BSJZF,atorvastatin,and 3-methyladenine groups.Syngeneic C57BL/6 mice of the same age were used for the control group.Autophagosomes in the aorta were examined by transmission electron microscopy.Morphology,lipid accumulation,and collagen deposition in the aorta were examined by hematoxylin and eosin,Oil Red O,and Masson's staining,respectively.Serum levels of tumor necrosis factor alpha(TNF-α),interferon gamma(IFN-γ),and interleukin 10(IL-10)were measured by enzyme-linked immunoassays.Protein expression of microtubule-associated protein light chain 3(LC3),Beclin 1,and p62 in the aorta were examined by Western blot analyses.RESULTS:ApoE^-/- mice fed a high fat diet exhibited AS symptoms including less autophagosomes in the aorta,higher serum levels of TNF-α,IFN-γ,and p62,and lower serum levels of IL-10,LC3,and Beclin 1.Treatment with BSJZF significantly reduced the area of the aortic plaque,decreased expression of TNF-α,IFN-γ,and p62,and increased expression of IL-10,LC3,and Beclin 1.CONCLUSION:Our findings suggest that BSJZF promotes autophagy and reduces inflammation by regulating the expression of autophagy-related proteins LC3,Beclin 1,and p62,thereby effectively treating AS.Cao Hui Jia Qingling Shen Dingzhu Yan Li Chen Chuan Xing Sanli Dou Fangfang 2020Journal of Traditional Chinese Medicine2020,40,4:3
