| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | Lp-PLA2 inhibition prevents Ang Ⅱ-induced cardiac inflammation and fibrosis by blocking macrophage NLRP3 inflammasome activation显示文摘Macrophage-mediated inflammation plays an important role in hypertensive cardiac remodeling,whereas effective pharmacological treatments targeting cardiac inflammation remain unclear.Lipoprotein-associated phospholipase A2(Lp-PLA2)contributes to vascular inflammation-related diseases by mediating macrophage migration and activation.Darapladib,the most advanced Lp-PLA2 inhibitor,has been evaluated in phase Ⅲ trials in atherosclerosis patients.However,the role of darapladib in inhibiting hypertensive cardiac fibrosis remains unknown.Using a murine angiotensin Ⅱ(Ang Ⅱ)infusion-induced hypertension model,we found that Pla2g7(the gene of Lp-PLA2)was the only upregulated PLA2 gene detected in hypertensive cardiac tissue,and it was primarily localized in heart-infiltrating macrophages.As expected,darapladib significantly prevented Ang Ⅱ-induced cardiac fibrosis,ventricular hypertrophy,and cardiac dysfunction,with potent abatement of macrophage infiltration and inflammatory response.RNA sequencing revealed that darapladib strongly downregulated the expression of genes and signaling pathways related to inflammation,extracellular matrix,and proliferation.Moreover,darapladib substantially reduced the Ang Ⅱ infusion-induced expression of nucleotide-binding oligomerization domain-like receptor with pyrin domain 3(NLRP3)and interleukin(IL)-1β and markedly attenuated caspase-1 activation in cardiac tissues.Furthermore,darapladib ameliorated Ang Ⅱ-stimulated macrophage migration and IL-1β secretion in macrophages by blocking NLRP3 inflammasome activation.Darapladib also effectively blocked macrophage-mediated transformation of fibroblasts into myofibroblasts by inhibiting the activation of the NLRP3 inflammasome in macrophages.Overall,our study identifies a novel anti-inflammatory and anti-cardiac fibrosis role of darapladib in Lp-PLA2 inhibition,elucidating the protective effects of suppressing NLRP3 inflammasome activation.Lp-PLA2 inhibition by darapladib represents a novel therapeutic strategy for hypertensive cardiac damage treatment. | Si-lin Lv Zi-fan Zeng Wen-qiang Gan Wei-qi Wang Tie-gang Li Yu-fang Hou Zheng Yan Ri-xin Zhang Min Yang | 2021 | Acta Pharmacologica Sinica2021，42，12： | 21 |
| 3 | Daclatasvir plus asunaprevir in treatment-na?ve patients with hepatitis C virus genotype 1b infection显示文摘AIM To assess daclatasvir plus asunaprevir(d UAL) in treatment-na?ve patients from China's Mainland, Russia and South Korea with hepatitis C virus(HCV) genotype 1 b infection. METHODS Patients were randomly assigned(3:1) to receive 24 wk of treatment with d UAL(daclatasvir 60 mg once daily and asunaprevir 100 mg twice daily) beginning on day 1 of the treatment period(immediate treatment arm) or following 12 wk of matching placebo(placebodeferred treatment arm). The primary endpoint was a comparison of sustained virologic response at posttreatment week 12(SVR12) compared with the historical SVR rate for peg-interferon plus ribavirin(70%) among patients in the immediate treatment arm. The first 12 wk of the study were blinded. Safety was assessed in d UAL-treated patients compared with placebo patients during the first 12 wk(doubleblind phase), and during 24 wk of d UAL in both arms combined.RESULTS In total, 207 patients were randomly assigned to immediate(n = 155) or placebo-deferred(n = 52) treatment. Most patients were Asian(86%), female(59%) and aged < 65 years(90%). Among them, 13% had cirrhosis, 32% had IL28 B non-CC genotypes and 53% had baseline HCV RNA levels of ≥ 6 million IU/m L. Among patients in the immediate treatment arm, SVR12 was achieved by 92%(95% confidence interval: 87.2-96.0), which was significantly higher than the historical comparator rate(70%). SVR12 was largely unaffected by cirrhosis(89%), age ≥ 65 years(92%), male sex(90%), baseline HCV RNA ≥ 6 million(89%) or IL28 B non-CC genotypes(96%), although SVR12 was higher among patients without(96%) than among those with(53%) baseline NS5 A resistanceassociated polymorphisms(at L31 or Y93 H). during the double-blind phase, aminotransferase elevations were more common among placebo recipients than among patients receiving d UAL. during 24 wk of d UAL therapy(combined arms), the most common adverse events(≥ 10%) were elevated alanine aminotransferase and upper respiratory tract infection; emergent grade 3-4 laboratory abnormalities were infrequently observed, and all grade 3-4 aminotransferase abnormalities(alanine aminotransferase, n = 9; aspartate transaminase, n = 6) reversed within 8-11 d. Two patients discontinued d UAL treatment; one due to aminotransferase elevations, nausea, and jaundice and the other due to a fatal adverse event unrelated to treatment. There were no treatment-related deaths.CONCLUSION d UAL was well-tolerated during this phase 3 study, and SVR12 with d UAL treatment(92%) exceeded thehistorical SVR rate for peg-interferon plus ribavirin of 70%. | Lai Wei Fu-Sheng Wang Ming-Xiang Zhang Ji-Dong Jia Alexey A Yakovlev Wen Xie Eduard Burnevich Jun-Qi Niu Yong Jin Jung Xiang-Jun Jiang Min Xu Xin-Yue Chen Qing Xie Jun Li Jin-Lin Hou Hong Tang Xiao-guang Dou Yash Gandhi Wen-Hua Hu Fiona McPhee Stephanie Noviello Michelle Treitel Ling Mo Jun Deng | 2018 | World Journal of Gastroenterology2018，24，12： | 17 |
| 4 | Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only. | Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao | 2019 | Cell Research2019，29，2： | 16 |

| 6 | Advanced oxidation protein products decrease expression of nephrin and podocin in podocytes via ROS-dependent activation of p38 MAPK显示文摘Accumulation of plasma advanced oxidation protein products(AOPPs) promotes progression of proteinuria and glomerulo-sclerosis.To investigate the molecular basis of AOPPs-induced proteinuria,normal Sprague-Dawley rats were treated with AOPPs-modified rat serum albumin.The expression of glomerular podocyte slit diaphragm(PSD)-associated proteins,nephrin and podocin,was significantly decreased coincident with the onset of albuminuria in rats treated with AOPPs.Chronic inhibi-tion of NADPH oxidase by apocynin prevented down-regulation of nephrin and podocin and decreased albuminuria in AOPPs-challenged rats.This suggested that accumulation of AOPPs promotes proteinuria,possibly via down-regulating the expression of PSD-associated proteins. | YANG Li,LIANG Min,ZHOU QiuGen,XIE Di,LOU AiJu,ZHANG Xun & HOU FanFan Key Laboratory for Organ Failure Research,Division of Nephrology,Nanfang Hospital,Southern Medical University,Guangzhou 510515,China. | 2010 | Science China(Life Sciences)2010，53，1： | 14 |
| 7 | Effect of Morinda officinalis capsule on osteoporosis in ovariectomized rats显示文摘AIM:To explore the therapeutic effects of Morinda officinalis capsules(MOP) on osteoporosis in ovariectomized rats.METHOD:Six-month-old female Sprague–Dawley rats were induced for postmenopausal osteoporosis(PMOP) by bilateral ovariectomy and divided into seven groups as follows:sham-operated group,ovariectomized(OVX) control group,OVX treated with xianlinggubao(XLGB)(270 mg·kg-1·d-1),OVX treated with alendronate sodium(ALN)(3 mg·kg-1·d-1),and OVX treated with Morinda officinalis capsule(MOP) of graded doses(90,270 and 810 mg·kg-1·d-1) groups.Oral treatments were administered daily on the 4th week after ovariectomy and lasted for 12 weeks.The bone mineral density was evaluated by dual-energy X-ray absorptiometry.The tartrate-resistant acid phosphatase(TRAP),alkaline phosphatase(AKP),and osteocalcin(OC) levels in the serum and plasma were determined by standard colorimetric and enzyme immunoassays methods.Bone biomechanical properties and morphological parameters were analyzed by three-point bending test and histomorphometry respectively.RESULTS:Morinda officinalis capsules at all doses were able to significantly prevent the OVX-induced loss of bone mass due to diminishing serum AKP and TRAP levels while elevating OC level in the plasma.Morinda officinalis capsules also enhanced the bone strength and prevented the deterioration of trabecular microarchitecture.CONCLUSION:Morinda officinalis capsules possess potent anti-osteoporotic activity in OVX rats which could be an effective treatment for postmenopausal osteoporosis. | LI Ye Lü Shan-Shan TANG Gui-Ying HOU Min TANG Qing ZHANG Xiao-Na CHEN Wei-Hai CHEN Gang XUE Qiang ZHANG Cong-Cong ZHANG Ji-Fen CHEN Yi XU Xiao-Yu | 2014 | Chinese Journal of Natural Medicines2014，12，3： | 10 |
| 8 | Peginterferon alfa-2a for the treatment of chronic hepatitis C in the era of direct-acting antivirals显示文摘BACKGROUND: The availability of novel direct-acting antivirals(DAAs) represents a new era of curative hepatitis C virus(HCV) treatment, with over 95% of patients infected with HCV genotype 1 achieving sustained virological response(SVR). Nevertheless, the majority of patients globally are unable to access these treatments because of cost and infrastructure constraints and, thus, remain untreated and uncured.DATA SOURCE: Relevant articles of peginterferon(Peg IFN)-based treatments in HCV and sofosbuvir-based treatments, simeprevir, daclatasvir/asunaprevir, ritonavir-boosted paritaprevir/ombitasvir/dasabuvir, and grazoprevir/elbasvir, were searched in Pub Med database, including general population and special population.RESULTS: Peg IFN in combination with ribavirin remains an important and relevant option for some patients, achieving SVR rates of up to 79% in genotype 1 and 89% in genotype 2 or 3 infections, which increases for patients with favorable IL28 B genotypes. Triple therapy of DAA plus Peg IFN/ribavirin is effective in treating difficult-to-cure patients infected with HCV genotype 3 or with resistance-associated variants. Owing to its long history in HCV management, the efficacy, tolerability and long-term outcomes associated with Peg IFN alfa-2a are well established and have been validated in largescale studies and in clinical practice for many populations. Furthermore, emerging data show that IFN-induced SVR is associated with lower incidences of hepatocellular carcinoma compared with DAAs. On the contrary, novel DAAs have yet to be studied in special populations, and long-term outcomes, particularly tumor development and recurrence in patients with cirrhosis and/or hepatocellular carcinoma, and reactivation of HBV in dually infected patients, are still unclear.CONCLUSION: In this interferon-free era, Peg IFN-based regimens remain a safe and effective option for selected HCV patients. | Yan Huang Ming-Hui Li Min Hou Yao Xie | 2017 | Hepatobiliary & Pancreatic Diseases International2017，16，5： | 10 |
| 9 | Chemical characteristics of size-resolved aerosols in winter in Beijing显示文摘Size-resolved aerosols were continuously collected by a Nano Sampler for 13 days at an urban site in Beijing during winter 2012 to measure the chemical composition of ambient aerosol particles. Data collected by the Nano Sampler and an ACSM(Aerodyne Aerosol Chemical Speciation Monitor) were compared. Between the data sets,similar trends and strong correlations were observed,demonstrating the validity of the Nano Sampler. PM10 and PM2.5concentrations during the measurement were 150.5 ± 96.0 μg/m3(mean ± standard variation)and 106.9 ± 71.6 μg/m3,respectively. The PM2.5/PM10 ratio was 0.70 ± 0.10,indicating that PM2.5dominated PM10. The aerosol size distributions showed that three size bins of 0.5–1,1–2.5 and 2.5–10 μm contributed 21.8%,23.3% and 26.0% to the total mass concentration(TMC),respectively. OM(organic matter) and SIA(secondary ionic aerosol,mainly SO42-,NO3-and NH4+) were major components of PM2.5. Secondary compounds(SIA and secondary organic carbon) accounted for half of TMC(about 49.8%) in PM2.5,and suggested that secondary aerosols significantly contributed to the serious particulate matter pollution observed in winter. Coal burning,biomass combustion,vehicle emissions and SIA were found to be the main sources of PM2.5. Mass concentrations of water-soluble ions and undetected materials,as well as their fractions in TMC,strikingly increased with deteriorating particle pollution conditions,while OM and EC(elemental carbon) exhibited different variations,with mass concentrations slightly increasing but fractions in TMC decreasing. | Kang Sun Yu Qu Qiong Wu Tingting Han Jianwei Gu Jingjing Zhao Yele Sun Qi Jiang Ziqi Gao Min Hu Yuanhang Zhang Keding Lu Stephan Nordmann Yafang Cheng Li Hou Hui Ge Masami Furuuchi Mitsuhiko Hata Xingang Liu | 2014 | Journal of Environmental Sciences2014，26，8： | 9 |
| 10 | A Confocal Endoscope for Cellular Imaging显示文摘Since its inception, endoscopy has aimed to establish an immediate diagnosis that is virtually consistent with a histologic diagnosis. In the past decade, confocal laser scanning microscopy has been brought into endoscopy, thus enabling in vivo microscopic tissue visualization with a magnification and resolution comparable to that obtained with the ex vivo microscopy of histological specimens. The major challenge in the development of instrumentation lies in the miniaturization of a fiber-optic probe for microscopic imaging with micron-scale resolution. Here, we present the design and construction of a confocal endoscope based on a fiber bundle with 1.4-μm lateral resolution and 8-frames per second(fps) imaging speed. The fiber-optic probe has a diameter of 2.6 mm that is compatible with the biopsy channel of a conventional endoscope. The prototype of a confocal endoscope has been used to observe epithelial cells of the gastrointestinal tracts of mice and will be further demonstrated in clinical trials. In addition, the confocal endoscope can be used for translational studies of epithelial function in order to monitor how molecules work and how cells interact in their natural environment. | Jiafu Wang Min Yang Li Yang Yun Zhang Jing Yuan Qian Liu Xiaohua Hou Ling Fu | 2015 | Engineering2015，1，3： | 9 |
| 11 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020，33，12： | 8 |
| 12 | Estrogenic activity of osthole and imperatorin in MCF-7 cells and their osteoblastic effects in Saos-2 cells显示文摘There is an increasing interest in phytoestrogens due to their potential medical usage in hormone replacement therapy(HRT). The present study was designed to investigate the in vitro effects of estrogen-like activities of two widespread coumarins, osthole and imperatorin, using the MCF-7 cell proliferation assay and their alkaline phosphatase(ALP) activities in osteoblasts Saos-2 cells. The two compounds were found to strongly stimulate the proliferation of MCF-7 cells. The estrogen receptor-regulated ERα, progesterone receptor(PR) and PS2 m RNA levels were increased by treatment with osthole and imperatorin. All these effects were significantly inhibited by the specific estrogen receptor antagonist ICI182, 780. Cell cycle analysis revealed that their proliferation stimulatory effect was associated with a marked increase in the number of MCF-7 cells in S phase, which was similar to that observed with estradiol. It was also observed that they significantly increased ALP activity, which was reversed by ICI182,780. These results suggested that osthole and imperatorin could stimulate osteoblastic activity by displaying estrogenic properties or through the ER pathway. In conclusion, osthole and imperatorin may represent new pharmacological tools for the treatment of osteoporosis. | JIA Min LI Yuan XIN Hai-Liang HOU Ting-Ting ZHANG Nai-Dai XU Hong-Tao ZHANG Qiao-Yan QIN Lu-Ping | 2016 | Chinese Journal of Natural Medicines2016，14，6： | 7 |
| 13 | Chemoprophylaxis, diagnosis, treatments, and discharge management of COVID-19: An evidence-based clinical practice guideline(updated version)显示文摘The novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is the cause of a rapidly spreading illness,coronavirus disease 2019(COVID-19),affecting more than seventeen million people around the world.Diagnosis and treatment guidelines for clinicians caring for patients are needed.In the early stage,we have issued'A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV)infected pneumonia(standard version)';now there are many direct evidences emerged and may change some of previous recommendations and it is ripe for develop an evidence-based guideline.We formed a working group of clinical experts and methodologists.The steering group members proposed 29 questions that are relevant to the management of COVID-19 covering the following areas:chemoprophylaxis,diagnosis,treatments,and discharge management.We searched the literature for direct evidence on the management of COVID-19,and assessed its certainty generated recommendations using the Grading of Recommendations,Assessment,Development and Evaluation(GRADE)approach.Recommendations were either strong or weak,or in the form of ungraded consensus-based statement.Finally,we issued 34 statements.Among them,6 were strong recommendations for,14 were weak recommendations for,3 were weak recommendations against and 11 were ungraded consensus-based statement.They covered topics of chemoprophylaxis(including agents and Traditional Chinese Medicine(TCM)agents),diagnosis(including clinical manifestations,reverse transcription-polymerase chain reaction(RT-PCR),respiratory tract specimens,IgM and IgG antibody tests,chest computed tomography,chest X-ray,and CT features of asymptomatic infections),treatments(including lopinavirritonavir,umifenovir,favipiravir,interferon,remdesivir,combination of antiviral drugs,hydroxychloroquine/chloroquine,interleukin-6 inhibitors,interleukin-1 inhibitors,glucocorticoid,qingfei paidu decoction,lianhua qingwen granules/capsules,convalescent plasma,lung transplantation,invasive or noninvasive ventilation,and extracorporeal membrane oxygenation(ECMO)),and discharge management(including discharge criteria and management plan in patients whose RT-PCR retesting shows SARS-CoV-2 positive after discharge).We also created two figures of these recommendations for the implementation purpose.We hope these recommendations can help support healthcare workers caring for COVID-19 patients. | Ying-Hui Jin Qing-Yuan Zhan Zhi-Yong Peng Xue-Qun Ren Xun-Tao Yin Lin Cai Yu-Feng Yuan Ji-Rong Yue Xiao-Chun Zhang Qi-Wen Yang Jianguang Ji Jian Xia Yi-Rong Li Fu-Xiang Zhou Ya-Dong Gao Zhui Yu Feng Xu Ming-Li Tu Li-Ming Tan Min Yang Fang Chen Xiao-Ju Zhang Mei Zeng Yu Zhu Xin-Can Liu Jian Yang Dong-Chi Zhao Yu-Feng Ding Ning Hou Fu-Bing Wang Hao Chen Yong-Gang Zhang Wei Li Wen Chen Yue-Xian Shi Xiu-Zhi Yang Xue-Jun Wang Yan-Jun Zhong Ming-Juan Zhao Bing-Hui Li Lin-Lu Ma Hao Zi Na Wang Yun-Yun Wang Shao-Fu Yu Lu-Yao Li Qiao Huang Hong Weng Xiang-Ying Ren Li-Sha Luo Man-Ru Fan Di Huang Hong-Yang Xue Lin-Xin Yu Jin-Ping Gao Tong Deng Xian-Tao Zeng Hong-Jun Li Zhen-Shun Cheng Xiao-Mei Yao Xing-Huan Wang | 2020 | Military Medical Research2020，7，3： | 6 |
| 14 | Three-dimensional physical simulation and optimization of water injection of a multi-well fractured-vuggy unit显示文摘With complex fraclured-vuggy heterogeneous structures,water has to be injected to facilitate oil production.However,the effect of different water injection modes on oil recovery varies.The limitation of existing numerical simulation methods in representing fracturedvuggy carbonate reservoirs makes numerical simulation difficult to characterize the fluid flow in these reservoirs.In this paper,based on a geological example unit in the Tahe Oilfield,a three-dimensional physical model was designed and constructed to simulate fluid flow in a fractured-vuggy reservoir according to similarity criteria.The model was validated by simulating a bottom water drive reservoir,and then subsequent water injection modes were optimized.These were continuous(constant rate),intermittent,and pulsed injection of water.Experimental results reveal that due to the unbalanced formation pressure caused by pulsed water injection,the swept volume was expanded and consequently the highest oil recovery increment was achieved.Similar to continuous water injection,intermittent injection was influenced by factors including the connectivity of the fractured-vuggy reservoir,well depth,and the injection-production relationship,which led to a relative low oil recovery.This study may provide a constructive guide to field production and for the development of the commercial numerical models specialized for fractured-vuggy carbonate reservoirs. | Ji-Rui HOU Ze-Yu Zheng Zhao-Jie Song Min LUO Hai-Bo Li Li Zhang Deng-Yu Yuan | 2016 | Petroleum Science2016，13，2： | 6 |
| 15 | Ultra-sensitive Nanoprobe Modified with Tumor Cell Membrane for UCL/MRI/PET Multimodality Precise Imaging of Triple-Negative Breast Cancer显示文摘Triple-negative breast cancer(TNBC)is a subtype of breast cancer in which the estrogen receptor and progesterone receptor are not expressed,and human epidermal growth factor receptor 2 is not amplified or overexpressed either,which make the clinical diagnosis and treatment very challenging.Molecular imaging can provide an effective way to diagnose TNBC.Upconversion nanoparticles(UCNPs),are a promising new generation of molecular imaging probes.However,UCNPs still need to be improved for tumor-targeting ability and biocompatibility.This study describes a novel probe based on cancer cell membrane-coated upconversion nanoparticles(CCm-UCNPs),owing to the low immunogenicity and homologous-targeting ability of cancer cell membranes,and modified multifunctional UCNPs.This probe exhibits excellent performance in breast cancer molecular classification and TNBC diagnosis through UCL/MRI/PET tri-modality imaging in vivo.By using this probe,MDA-MB-231 was successfully differentiated between MCF-7 tumor models in vivo.Based on the tumor imaging and molecular classification results,the probe is also expected to be modified for drug delivery in the future,contributing to the treatment of TNBC.The combination of nanoparticles with biomimetic cell membranes has the potential for multiple clinical applications. | Hanyi Fang Mengting Li Qingyao Liu Yongkang Gai Lujie Yuan Sheng Wang Xiao Zhang Min Ye Yongxue Zhang Mingyuan Gao Yi Hou Xiaoli Lan | 2020 | Nano-Micro Letters2020，12，5： | 5 |
| 16 | Environmental and Psycho-social Factors Related to Prostate Cancer Risk in the Chinese Population:a Case-control Study显示文摘Objective To study the risk environmental and psycho-social factors associated to prostate cancer(PCa) in Chinese population. Methods 250 PCa patients and 500 controls were enrolled in this case-control study. Information was collected and logistic regression analysis was used to estimate the odds ratios(OR) and 95% confidence intervals(95% CI) for relationship between lifestyle, eating habits and psycho-social factors with PCa risk. Results Green vegetables and green tea were associated with a decreased risk of PCa(OR=0.39, 95% CI: 0.28-0.53; OR=0.59, 95% CI: 0.40-0.87, respectively). Family history of PCa(OR=7.16, 95% CI: 2.01-25.49), history of prostate diseases(OR=2.28, 95% CI: 1.53-3.41), alcohol consumption(OR=1.97, 95% CI: 1.33-2.90), red meat consumption(OR=1.74, 95% CI: 1.20-2.52), barbecued(OR=2.29, 95% CI: 1.11-4.73) or fried(OR=2.35, 95% CI: 1.24-4.43) foods were related with increased PCa risk. Negative psycho-social factors including occupational setbacks(OR=1.61, 95% CI: 1.00-2.59), marital separation(OR=1.94, 95% CI: 1.29-2.91), self-contained suffering(OR=2.37, 95% CI: 1.58-3.55), and high sensitivity to the personal comments(OR=1.73, 95% CI: 1.18-2.54) were related to PCa. Conclusion Regular consumption of green vegetables and green tea may suggest protective effects on PCa. Alcohol consumption, red meat consumption and barbecued or fried foods were associated with PCa. Negative psycho-social factors may also play a role in the incidence of PCa in Chinese population. | LI Mei Ling LIN Ji HOU Jian Guo XU Lei CUI Xin Gang XU Xing Xing YU Yong Wei HAN Xue WANG Guo Min GUO Jian Ming XU Dan Feng THOMPSON Timothy C CAO Guang Wen ZHANG Hong Wei | 2014 | Biomedical and Environmental Sciences2014，27，9： | 5 |
| 17 | Mesenchymal stem cell treatment improves outcome of COVID-19 patients via multiple immunomodulatory mechanisms显示文摘The infusion of coronavirus disease 2019(COVID-19)patients with mesenchymal stem cells(MSCs)potentially improves clinical symptoms,but the underlying mechanism remains unclear.We conducted a randomized,single-blind,placebo-controlled(29 patients/group)phase II clinical trial to validate previous findings and explore the potential mechanisms.Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay(P=0.0198)and less time required for symptoms remission(P=0.0194)than those who received placebo.Based on chest images,both severe and critical patients treated with MSCs showed improvement by day 7(P=0.0099)and day 21(P=0.0084).MSC-treated patients had fewer adverse events.MSC infusion reduced the levels of C-reactive protein,proinflammatory cytokines,and neutrophil extracellular traps(NETs)and promoted the maintenance of SARS-CoV-2-specific antibodies.To explore how MSCs modulate the immune system,we employed single-cell RNA sequencing analysis on peripheral blood.Our analysis identified a novel subpopulation of VNN2+hematopoietic stem/progenitorlike(HSPC-like)cells expressing CSF3R and PTPRE that were mobilized following MSC infusion.Genes encoding chemotaxis factors—CX3CR1 and L-selectin—were upregulated in various immune cells.MSC treatment also regulated B cell subsets and increased the expression of costimulatory CD28 in T cells in vivo and in vitro.In addition,an in vivo mouse study confirmed that MSCs suppressed NET release and reduced venous thrombosis by upregulating kindlin-3 signaling.Together,our results underscore the role of MSCs in improving COVID-19 patient outcomes via maintenance of immune homeostasis. | Rongjia Zhu Tingdong Yan Yingmei Feng Yan Liu Hongcui Cao Gongxin Peng Yanlei Yang Zhen Xu Jingqi Liu Wei Hou Xiaoyue Wang Zhe Li Luchan Deng Shihua Wang Jing Li Qin Han Hongling Li Guangliang Shan Yinghao Cao Xingyan An Jianshe Yan Zhonghui Zhang Huafei Li Xuebin Qu Jiaqi Zhu Shumin Zhou Jiao Wang Fengchun Zhang Jinming Gao Ronghua Jin Dayong Xu Yan-Qing Ma Tao Huang Shuang Peng Zhi Zheng Ilia Stambler Eric Gilson Lee Wei Lim Alexey Moskalev Antonio Cano Sasanka Chakrabarti Brun Ulfhake Huanxing Su Haoying Xu Sihuan Xu Feng Wei Holly MBrown-Borg Kyung-Jin Min Georgina Ellison-Hughes Calogero Caruso Kunlin Jin Robert Chunhua Zhao | 2021 | Cell Research2021，31，12： | 5 |

| 19 | The cytotoxicity and protective effects of Astragalus membranaceus extracts and butylated hydroxyanisole on hydroxyl radical-induced apoptosis in fish erythrocytes显示文摘Erythrocytes play an essential role in transporting O_2 and CO_2 for respiration in fish. However,erythrocytes continuously suffer from reactive oxygen species(ROS)-induced oxidative stress and apoptosis. Thus, it is essential to expand our knowledge of how to protect erythrocytes against ROS-induced oxidative stress and apoptosis in fish. In this study, we explored the cytotoxicity and the effects of butylated hydroxyanisole(BHA), ethyl ether extracts, ethyl acetate extracts, acetone extracts(AE), ethanol extracts, and aqueous extracts of Astragalus membranaceus(EAm) on hydroxyl radical(·OH)-induced apoptosis in carp erythrocytes. The rat hepatocytes and carp erythrocytes were incubated with different concentrations of BHA or EAm(0.125 to 1 mg/mL). The toxicity in rat hepatocytes and carp erythrocytes was then measured using a 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide(MTT) assay and a haemolysis assay,respectively. The carp erythrocytes were treated with BHA or EAm in the presence of 40 μmol/L FeSO4 and20 μmol/L H_2 O_2 at 37℃, except for the control group. Oxidative stress and apoptosis parameters in the carp erythrocytes were then evaluated using the commercial kit. The results indicated that at high concentrations, BHA and EAm could induce toxicity in rat hepatocytes and fish erythrocytes. However, BHA was more toxic than EAm at the same concentrations. Moreover, the toxicity order of BHA and EAm in the fish erythrocytes approximately agreed with that for the rat hepatocytes. Butylated hydroxyanisole and EAm suppressed the ·OH-induced phosphatidylserine exposure and DNA fragmentation(the biomarkers of apoptosis) by decreasing the generation of ROS, inhibiting the oxidation of cellular components, and restoring the activities of antioxidants in carp erythrocytes. Of all of the examined EAm, the AE showed the strongest effects. The effects of AE on superoxide anion, H_2 O_2, met-haemoglobin and reduced glutathione levels, as well as glutathione reductase activity and apoptosis were equivalent to or stronger than those of BHA. These results revealed that the AE of Astragalus membranaceus could be used as a potential natural antioxidant or apoptosis inhibitor in fish erythrocytes. | Huatao Li Xiaoqiu Zhou Min Wu Mengling Deng Chao Wang Jingjing Hou Pengju Mou | 2016 | Animal Nutrition2016，，4： | 5 |
| 20 | Resource flow:Autonomous cognitive resource management framework for future networks显示文摘From an end-to-end performance perspective,a multi-agent-based cognitive resource management(MA-CRM) framework is proposed in this article.More importantly,we introduce a novel concept of resource flow(RF) as integrated CRM in a multi-dimensional environment scenario.We concentrate on the autonomous CRM framework in cognitive radio(CR) networks.Specifically,we first summarize the necessity of the novel concept for implementing intelligent and autonomous resource management considering both the requirements of various types of resource and the unified framework of the CRM scheme.Then,we introduce the concept of RF,including the technical aspects,purpose,classification,and description.Finally,we give a use case of RF for autonomous CRM,where the optimal RF is achieved to guarantee the resource-imbalanced requests of different service traffic flows. | YANG ChunGang LI JianDong SHENG Min LIU Qin HOU RongHui LI HongYan | 2012 | Chinese Science Bulletin2012，57，28： | 4 |
