| 2 | Coding metamaterials, digital metamaterials and programmable metamaterials显示文摘Metamaterials are artificial structures that are usually described by effective medium parameters on the macroscopic scale,and these metamaterials are referred to as‘analog metamaterials’.Here,we propose‘digital metamaterials’through two steps.First,we present‘coding metamaterials’that are composed of only two types of unit cells,with 0 and p phase responses,which we name‘0’and‘1’elements,respectively.By coding‘0’and‘1’elements with controlled sequences(i.e.,1-bit coding),we can manipulate electromagnetic(EM)waves and realize different functionalities.The concept of coding metamaterials can be extended from 1-bit coding to 2-bit coding or higher.In 2-bit coding,four types of unit cells,with phase responses of 0,p/2,p,and 3p/2,are required to mimic the‘00’,‘01’,‘10’and‘11’elements,respectively.The 2-bit coding has greater freedom than 1-bit coding for controlling EM waves.Second,we propose a unique metamaterial particle that has either a‘0’or‘1’response controlled by a biased diode.Based on this particle,we present‘digital metamaterials’with unit cells that possess either a‘0’or‘1’state.Using a field-programmable gate array,we realize digital control over the digital metamaterial.By programming different coding sequences,a single digital metamaterial has the ability to manipulate EM waves in different manners,thereby realizing‘programmable metamaterials’.The above concepts and physical phenomena are confirmed through numerical simulations and experiments using metasurfaces. | Tie Jun Cui Mei Qing Qi Xiang Wan Jie Zhao Qiang Cheng | 2014 | Light(Science & Applications)2014，3，1： | 130 |

| 6 | Efficacy and safety of bevacizumab plus chemotherapy in Chinese patients with metastatic colorectal cancer:a randomized phase Ⅲ ARTIST trial显示文摘The efficacy and safety of bevacizumab with modified irinotecan,leucovorin bolus,and 5-fluorouracil intravenous infusion(mIFL) in the first-line treatment of metastatic colorectal cancer(mCRC) has not been well evaluated in randomized clinical trials in Chinese patients.We conducted a phrase Ⅲ trial in which patients with previously untreated mCRC were randomized 2:1 to the mIFL [irinotecan(125 mg/m2),leucovorin(20 mg/m2) bolus,and 5-fluorouracil intravenous infusion(500 mg/m2) weekly for four weeks every six weeks] plus bevacizumab(5 mg/kg every two weeks) group and the mIFL group,respectively.Co-primary objectives were progression-free survival(PFS) and 6-month PFS rate.In total,214 patients were enrolled.Our results showed that addition of bevacizumab to mIFL significantly improved median PFS(4.2 months in the mIFL group vs.8.3 months in the bevacizumab plus mIFL group,P < 0.001),6-month PFS rate(25.0% vs.62.6%,P < 0.001),median overall survival(13.4 months vs.18.7 months,P = 0.014),and response rate(17% vs.35%,P = 0.013).Grades 3 and 4 adverse events included diarrhea(21% in the mIFL group and 26% in the bevacizumab plus mIFL group) and neutropenia(19% in the mIFL group and 33% in the bevacizumab plus mIFL group).No wound-healing complications or congestive heart failure occurred.Our results suggested that bevacizumab plus mIFL is effective and well tolerated as first-line treatment for Chinese patients with mCRC.Clinical benefit and safety profiles were consistent with those observed in pivotal phase Ⅲ trials with mainly Caucasian patients. | Zhong-Zhen Guan Jian-Ming Xu Rong-Cheng Luo Feng-Yi Feng Li-Wei Wang Lin Shen Shi-Ying Yu Yi Ba Jun Liang Dong Wang Shu-Kui Qin Jie-Jun Wang Jing He Chuan Qi Rui-Hua Xu | 2011 | Chinese Journal of Cancer2011，30，10： | 48 |
| 7 | Programmable time-domain digital-coding metasurface for non-linear harmonic manipulation and new wireless communication systems显示文摘Optical non-linear phenomena are typically observed in natural materials interacting with light at high intensities, and they benefit a diverse range of applications from communication to sensing. However,controlling harmonic conversion with high efficiency and flexibility remains a major issue in modern optical and radio-frequency systems. Here, we introduce a dynamic time-domain digital-coding metasurface that enables efficient manipulation of spectral harmonic distribution. By dynamically modulating the local phase of the surface reflectivity, we achieve accurate control of different harmonics in a highly programmable and dynamic fashion, enabling unusual responses, such as velocity illusion. As a relevant application, we propose and realize a novel architecture for wireless communication systems based on the time-domain digital-coding metasurface, which largely simplifies the architecture of modern communication systems, at the same time yielding excellent performance for real-time signal transmission. The presented work, from new concept to new system, opens new pathways in the application of metamaterials to practical technology. | Jie Zhao Xi Yang Jun Yan Dai Qiang Cheng Xiang Li Ning Hua Qi Jun Chen Ke Guo Dong Bai Shuo Liu Shi Jin Andrea Alù Tie Jun Cui | 2019 | National Science Review2019，6，2： | 46 |
| 8 | Molecular Cytogenetic Characterization of Wheat-Thinopyrum elongatum Addition,Substitution and Translocation Lines with a Novel Source of Resistance to Wheat Fusarium Head Blight显示文摘Thinopyrum elongatum(2n = 2x = 14,EE),a wild relative of wheat,has been suggested as a potentially novel source of resistance to several major wheat diseases including Fusarium Head Blight(FHB).In this study,a series of wheat(cv.Chinese Spring,CS) substitution and ditelosomic lines,including Th.elongatum additions,were assessed for TypeⅡresistance to FHB.Results indicated that the lines containing chromosome 7E of Th.elongatum gave a high level of resistance to FHB,wherein the infection did not spread beyond the inoculated floret.Furthermore,it was determined that the novel resistance gene(s) of 7E was located on the short-arm(7ES) based on sharp difference in FHB resistance between the two 7E ditelosomic lines for each arm.On the other hand,Th.elongatum chromosomes 5E and 6E likely contain gene(s) for susceptibility to FHB because the disease spreads rapidly within the inoculated spikes of these lines. Genomic in situ hybridization(GISH) analysis revealed that the alien chromosomes in the addition and substitution lines were intact,and the lines did not contain discernible genomic aberrations.GISH and multicolor-GISH analyses were further performed on three translocation lines that also showed high levels of resistance to FHB.Lines TA3499 and TA3695 were shown to contain one pair of wheat-Th. elongatum translocated chromosomes involving fragments of 7D plus a segment of the 7E,while line TA3493 was found to contain one pair of wheat-Th.elongatum translocated chromosomes involving the D- and A-genome chromosomes of wheat.Thus,this study has established that the short-arm of chromosome 7E of Th.elongatum harbors gene(s) highly resistant to the spreading of FHB,and chromatin of 7E introgressed into wheat chromosomes largely retained the resistance,implicating the feasibility of using these lines as novel material for breeding FHB-resistant wheat cultivars. | Shulan Fu Zhenling Lv Bao Qi Xiang Guo Jun Li Bao Liu Fangpu Han | 2012 | Journal of Genetics and Genomics2012，39，2： | 35 |
| 9 | Prognostic factors and failure patterns in non-metastatic nasopharyngeal carcinoma after intensity-modulated radiotherapy显示文摘Background: The prognostic values of staging parameters require continual re?assessment amid changes in diag?nostic and therapeutic methods. This study aimed to identify the prognostic factors and failure patterns of non?meta?static nasopharyngeal carcinoma(NPC) in the intensity?modulated radiotherapy(IMRT) era.Methods: We reviewed the data from 749 patients with newly diagnosed, biopsy?proven, non?metastatic NPC in our cancer center(South China, an NPC endemic area) between January 2003 and December 2007. All patients under?went magnetic resonance imaging(MRI) before receiving IMRT. The actuarial survival rates were estimated using the Kaplan–Meier method, and survival curves were compared using the log?rank test. Multivariate analyses with the Cox proportional hazards model were used to test for the independent prognostic factors by backward eliminating insigniicant explanatory variables.Results: The 5?year occurrence rates of local failure, regional failure, locoregional failure, and distant failure were 5.4, 3.0, 7.4, and 17.4%, respectively. The 5?year survival rates were as follows: local relapse?free survival, 94.6%; nodal relapse?free survival, 97.0%; distant metastasis?free survival, 82.6%; disease?free survival, 75.1%; and overall survival, 82.0%. Multivariate Cox regression analysis revealed that orbit involvement was the only signiicant prognostic fac?tor for local failure(P = 0.011). Parapharyngeal tumor extension, retropharyngeal lymph node involvement, and the laterality, longest diameter, and Ho's location of the cervical lymph nodes were signiicant prognostic factors for both distant failure and disease failure(all P < 0.05). Intracranial extension had signiicant prognostic value for distant failure(P = 0.040).Conclusions: The key failure pattern for NPC was distant metastasis in the IMRT era. With changes in diagnostic and therapeutic technologies as well as treatment modalities, the signiicant prognostic parameters for local control have also been altered substantially. | Yan-Ping Mao Ling-Long Tang Lei Chen Ying Sun Zhen-Yu Qi Guan-Qun Zhou Li-Zhi Liu Li Li Ai-Hua Lin Jun Ma | 2016 | Chinese Journal of Cancer2016，35，12： | 39 |
| 10 | Hypermethylation and expression regulation of secreted frizzled-related protein genes in colorectal tumor显示文摘AIM: To investigate the functions of promoter hyper- methylation of secreted frizzled-related proteins (sFRPs) genes in colorectal tumorigenesis and progression. METHODS: The promoter hypermethylation and expression of sFRP genes in 72 sporadic colorectal carcinomas, 33 adenomas, 18 aberrant crypt foci (ACF) and colorectal cancer cell lines RKO, HCT116 and SW480 were detected by methylation-specific PCR and reverse transcription PCR, respectively. RESULTS: None of the normal colorectal mucosa tissues showed methylated bands of any of four sFRP genes. sFRP1, 2, 4 and 5 were frequently methylated in colorectal carcinoma, adenoma and ACF (sFRP1 > 85%, sFRP2 >75%, sFRP5 > 50%), and the differences between three colorectal tissues were not significant (P > 0.05). Methylation in colorectal tumors was more frequent than in normal mucosa and adjacent normal mucosa. The mRNA of sFRP1-5 genes was expressed in all normal colorectal mucosa samples. Expression of sFRP1, 2, 4 and 5 and sFRP1 , 2 and 5 was downregulated in carcinoma and adenoma, respectively. The downregulation of sFRP2, 4 and 5 was more frequent in carcinoma than in adenoma. Expression of sFRP3 which promoter has no CpG island was downregulated in only a few of colorectal tumor samples (7/105). The downregulation of sFRP1, 2, 4 and 5 expression was significantly associated with promoter hypermethylation in colorectal tumor. After cells were treated by DAC/TSA combination, the silenced sFRP mRNA expression could be effectively re-expressed in colorectal cancer cell lines.CONCLUSION: Hypermethylation of sFRP genes is acommon early event in the evolution of colorectal tumor, occurring frequently in ACF, which is regarded as the earliest lesion of multistage colorectal carcinogenesis. It appears to functionally silence sFRP genes expression. Methylation of sFRP1, 2 and 5 genes might serve as indicators for colorectal tumor. | Jian Qi You-Qing Zhu Jun Luo Wen-Hui Tao | 2006 | World Journal of Gastroenterology2006，12，44： | 34 |
| 11 | A novel m6A reader Prrc2a controls oligodendroglial specification and myelination显示文摘While N6-methyladenosine (m6A), the most abundant internal modification in eukaryotic mRNA, is linked to cell differentiation and tissue development, the biological significance of m6A modification in mammalian glial development remains unknown. Here, we identify a novel m6A reader, Prrc2a (Proline rich coiled-coil 2A), which controls oligodendrocyte specification and myelination. Nestin-Cre-mediated knockout of Prrc2a induces significant hypomyelination, decreased lifespan, as well as locomotive and cognitive defects in a mouse model. Further analyses reveal that Prrc2a is involved in oligodendrocyte progenitor cells (OPCs) proliferation and oligodendrocyte fate determination. Accordingly, oligodendroglial-lineage specific deletion of Prrc2a causes a similar phenotype of Nestin-Cre-mediated deletion. Combining transcriptome-wide RNA-seq, m6A-RIP-seq and Prrc2a RIP-seq analysis, we find that Olig2 is a critical downstream target gene of Prrc2a in oligodendrocyte development. Furthermore, Prrc2a stabilizes Olig2 mRNA through binding to a consensus GGACU motif in the Olig2 CDS (coding sequence) in an m6A-dependent manner. Interestingly, we also find that the m6A demethylase, Fto, erases the m6A modification of Olig2 mRNA and promotes its degradation. Together, our results indicate that Prrc2a plays an important role in oligodendrocyte specification through functioning as a novel m6A reader. These findings suggest a new avenue for the development of therapeutic strategies for hypomyelination-related neurological diseases. | Rong Wu Ang Li Baofa Sun Jian-Guang Sun Jinhua Zhang Ting Zhang Yusheng Chen Yujie Xiao Yuhao Gao Qingyang Zhang Jun Ma Xin Yang Yajin Liao Wei-Yi Lai Xiaolong Qi Shukun Wang Yousheng Shu Hai-Lin Wang Fengchao Wang Yun-Gui Yang Zengqiang Yuan | 2019 | Cell Research2019，29，1： | 32 |
| 12 | Clinical short-term results of radiofrequency ablation in liver cancers显示文摘AIM: To study local therapeutic efficacy, side effects, andcomplications of radiofrequency ablation (RFA), whichis emerging as a new method for the treatment ofpatients with hepatocellular carcinoma (HCC) withcirrhosis or chronic hepatitis and metastatic liver cancer.METHODS: Thirty-six patients with primary andsecondary liver cancers (21 with primaryhepatocellular carcinoma, 12 with colorectal cancerliver metastases and 3 with other malignant livermetastases), which were considered not suitable forcurative resection, were include in this study. Theywere treated either with RFA (RITA2000, MountainView, California, USA) percutaneously (n=20)orintraoperatively (n=16).The procedures wereperformed using the ultrasound guidance. The qualityof RFA were based on monitoring of equipments andsubject feeling of the practitioners. Patients treatedwith RFA was followed according to clinical findings,radiographic images, and tumor markers.RESULTS: Thirty-six patients underwent RFA for 48nodules. RFA was used to treat an average 1.3 lesionsper patient, and the median size of treated lesions was2.5 cm (range, 0.5-9 cm). The average hospital staywas 5.6 days overall (2.8 days for percutaneous casesand 7.9 days for open operations). Seven patientsunderwent a second RFA procedure (sequentialablations). Sixteen HCC patients with a high level ofalpha fetoprotein (AFP) and 9 colorectal cancer livermetastases patients with a high level of serumcarcinoembryonic antigen (CEA) have a great reductionbenefited from RFA. Four (11.1 %) patients hadcomplications: one skin burn; one postoperativehemorrhage; one cholecystitis and one hepatic abscessassociated with percutaneous ablations of a largelesion. There were 4 deaths: 3 patients died from localand system diseases (1 at 7 month, 1 at 9 month, and 1at 12 month), 1 patients died from cardiovascular shock,but no RFA-related death. At a median follow-up of 10months (range, 1-24 months), 6 patients (16.7 %) hadrecurrences at an RFA site, and 20 patients (56.7 %)remained clinically free of disease.CONCLUSION: RF ablation appears to be an effective,safe, and relatively simple procedure for the treatmentof unresectable liver cancers. The rate and severity ofcomplications appear acceptable. However, furtherstudy is necessary to assess combination with othertherapies, long-term recurrence rates and effect onoverall survival. | Hong-Chi Jiang Lian-Xin Liu Da-Xun Piao Jun Xu An-Long Zhu Wei-Hui Zhang Lin-Feng Wu Department of Surgery,the First Clinical College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Min Zheng Department of Ultrasound Diagnosis,the First Clinical College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Shu-Yi Qi Second Inpatient Department,the First Clinical College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China | 2002 | World Journal of Gastroenterology2002，8，4： | 33 |

| 14 | Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design. | SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 23 |
| 15 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 16 | The first all-season sample set for mapping global land cover with Landsat-8 data显示文摘We report the world's first all-season training and validation sample sets for global land cover classification with Landsat-8 data.Prior to this,such samples were only available at a single date primarily from the growing season.It is unknown how much limitation such a single-date sample has to mapping global land cover in other seasons of the year.To answer this question,we selected available Landsat-8 images from four seasons and collected training and validation samples from them.We compared the performances of training samples in different seasons using Random Forest algorithm.We found that the use of training samples from any individual season would result in the best overall classification accuracy when validated by samples in the same season.The global overall accuracy from combined best seasonal results was 67.2% when classifying the 11 Level-1 classes in the Finer Resolution Observation and Monitoring of Global Land Cover(FROM-GLC) classification system.The use of training samples from all seasons(named all-season training sample set hereafter) produced an overall accuracy of 67.0%.We also tested classification within 10° latitude 60° longitude zones using all-season training subsample within each zone and obtained an overall accuracy of 70.2%.This indicates that properly grouped subsamples in space can help improve classification accuracies.All the results in this study seem to suggest that it is possible to use an all-season training sample set to reach global optimality with universal applicability in classifying images acquired at any time of a year for global land cover mapping. | Congcong Li Peng Gong Jie Wang Zhiliang Zhu Gregory S.

| 17 | Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure显示文摘AIM:To study the clinical efficacy of traditional Chinese medicine(TCM)intervention'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')for treating liver failure due to chronic hepatitis B.METHODS:We designed the study as a randomized controlled clinical trial.Registration number of Chinese Clinical Trial Registry is Chi CTR-TRC-12002961.A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study.Participants were randomly assigned to the following three groups:(1)a modern medicine control group(MMC group,36patients);(2)a'tonifying qi and detoxification'('TQD')group(72 patients);and(3)a'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')group(36patients).Patients in the MMC group received general internal medicine treatment;patients in the'TQD'group were given a TCM formula'tonifying qi and detoxification'and general internal medicine treatment;patients in the'TTK'group were given a TCM formula of'TTK'and general internal medicine treatment.All participants were treated for 8 wk and then followed at 48 wk following their final treatment.The primaryefficacy end point was the patient fatality rate in each group.Measurements of various virological and biochemical indicators served as secondary endpoints.The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups.RESULTS:At the 48-wk post-treatment time point,the patient fatality rates in the MMC,'TQD',and'TTK'groups were 51.61%,35.38%,and 16.67%,respectively,and the differences between groups were statistically significant(P<0.05).However,there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups(P>0.05).Patients in the'TTK'group had significantly higher levels of serum total bilirubin compared to MMC subjects(339.40μmol/L±270.09μmol/L vs 176.13μmol/L±185.70μmol/L,P=0.014).Serum albumin levels were significantly increased in both the'TQD'group and'TTK'group as compared with the MMC group(31.30 g/L±4.77g/L,30.72 g/L±2.89 g/L vs 28.57 g/L±4.56 g/L,P<0.05).There were no significant differences in levels of alanine transaminase among the three groups(P>0.05).Safety data showed that there was one case of stomachache in the'TQD'group and one case of gastrointestinal side effect in the'TTK'group.CONCLUSION:Treatment with'TTK'improved the survival rates of patients with liver failure due to chronic hepatitis B.Additionally,liver tissue was regenerated and liver function was restored. | Han-Min Li Zhi-Hua Ye Jun Zhang Xiang Gao Yan-Ming Chen Xin Yao Jian-Xun Gu Lei Zhan Yang Ji Jian-Liang Xu Ying-He Zeng Fan Yang Lin Xiao Guo-Guang Sheng Wei Xin Qi Long Qing-Jing Zhu Zhao-Hong Shi Lian-Guo Ruan Jia-Yao Yang Chang-Chun Li Hong-Bin Wu Sheng-Duo Chen Xin-La Luo | 2014 | World Journal of Gastroenterology2014，20，48： | 20 |
| 18 | Effect of moxibustion on mTOR-mediated autophagy in rotenone-induced Parkinson's disease model rats显示文摘Defects in autophagy-mediated clearance of α-synuclein may be one of the key factors leading to progressive loss of dopaminergic neurons in the substantia nigra. Moxibustion therapy for Parkinson's disease has been shown to have a positive effect, but the underlying mechanism remains unknown. Based on this, we explored whether moxibustion could protect dopaminergic neurons by promoting autophagy mediated by mammalian target of rapamycin(m TOR), with subsequent elimination of α-syn. A Parkinson's disease model was induced in rats by subcutaneous injection of rotenone at the back of their necks, and they received moxibustion at Zusanli(ST36), Guanyuan(CV4) and Fengfu(GV16), for 10 minutes at every point, once per day, for 14 consecutive days. Model rats without any treatment were used as a sham control. Compared with the Parkinson's disease group, the moxibustion group showed significantly greater tyrosine hydroxylase immunoreactivity and expression of light chain 3-Ⅱ protein in the substantia nigra, and their behavioral score, α-synuclein immunoreactivity, the expression of phosphorylated m TOR and phosphorylated ribosomal protein S6 kinase(p-p70S6K) in the substantia nigra were significantly lower. These results suggest that moxibustion can promote the autophagic clearance of α-syn and improve behavioral performance in Parkinson's disease model rats. The protective mechanism may be associated with suppression of the m TOR/p70S6K pathway. | Shu-ju Wang Qi Wang Jun Ma Pei-hao Yu Zhong-ming Wang Bin Wang | 2018 | Neural Regeneration Research2018，13，1： | 18 |
| 19 | Characteristics of elemental carbon and organic carbon in PM_(10) during spring and autumn in Chongqing,China显示文摘PM10 (particulate matter with aerodynamic diameter less than 10 m) samples were collected simultaneously at nine urban sites and one urbanbackground site during two intensive observation campaigns in 2006. Concentrations of elemental carbon (EC) and organic carbon (OC) in PM10were analyzed using an element analyzer. The characteristics regarding spatial and seasonal distribution patterns of OC and EC concentrations andtheir contributions to PM10 mass, as well as correlation between OC and EC, were investigated in detail. The average OC and EC concentrationsfor urban sites were 57.5 ± 20.8 and 8.3 ± 3.9 g/m3, respectively, both being around three times higher than those for urban background site. As awhole, EC concentrations did not show distinct seasonal variations, though OC concentrations were generally higher in autumn than in spring. Forurban sites, total carbonaceous aerosol (TCA) accounted for 33.2% in spring and 35.0% in autumn of PM10 mass. The OC and EC concentrationswere found significantly correlated to each other both in spring and in autumn, implying the existence of similar emission sources such as coalcombustion. The OC/EC ratios generally exceeded 2.0, indicating the presence of secondary organic carbon (SOC), whose estimated concentrationfor urban Chongqing was 26.7 and 39.4 g/m3, accounting for 48.9 and 61.9% of the total OC observed in the samples, in spring and in autumn,respectively. | Di Ye Qi Zhao Changtan Jiang Jun Chen Xiaoxing Meng | 2007 | China Particuology2007，5，4： | 17 |
| 20 | Deletion of TLR4 attenuates lipopolysaccharide-induced acute liver injury by inhibiting inflammation and apoptosis显示文摘Septic acute liver injury is one of the leading causes of fatalities in patients with sepsis.Toll-like receptor 4(TLR4)plays a vital role in response to lipopolysaccharide(LPS)challenge,but the mechanisms underlying TLR4 function in septic injury remains unclear.In this study,we investigated the role of TLR4 in LPS-induced acute liver injury(ALI)in mice with a focus on inflammation and apoptosis.Wild-type(WT)and TLR4-knockout(TLR4^(−/−))mice were challenged with LPS(4 mg/kg)for 6 h.TLR4 signaling cascade markers(TLR4,MyD88,and NF-κB),inflammatory markers(TNFα,IL-1β,and IL-6),and apoptotic markers(Bax,Bcl-2,and caspase 3)were evaluated.We showed that LPS challenge markedly increased the levels of serum alanine aminotransferase(ALT)/aspartate aminotransferase(AST)and other liver pathological changes in WT mice.In addition,LPS challenge elevated the levels of liver carbonyl proteins and serum inflammatory cytokines,upregulated the expression of TLR4,MyD88,and phosphorylated NF-κB in liver tissues.Moreover,LPS challenge significantly increased hepatocyte apoptosis,caspase 3 activity,and Bax level while suppressing Bcl-2 expression in liver tissues.These pathological changes were greatly attenuated in TLR4^(−/−)mice.Similar pathological responses were provoked in primary hepatic Kupffer cells isolated from WT and TLR4^(−/−)mice following LPS(1μg/mL,6 h)challenge.In summary,these results demonstrate that silencing of TLR4 attenuates LPS-induced liver injury through inhibition of inflammation and apoptosis via TLR4/MyD88/NF-κB signaling pathway.TLR4 deletion confers hepatoprotection against ALI induced by LPS,possibly by repressing macrophage inflammation and apoptosis. | Sai-nan Chen Ying Tan Xiao-chan Xiao Qian Li Qi Wu You-you Peng Jun Ren Mao-long Dong | 2021 | Acta Pharmacologica Sinica2021，42，10： | 17 |
