| 1 | Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants. | Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He | 2021 | National Science Review2021，8，2： | 47 |
| 2 | Circular RNA PIP5K1A promotes colon cancer development through inhibiting mi R-1273a显示文摘BACKGROUND Circular RNAs (circRNAs) are considered to be highly stable due to the closed structure, which are predominately correlated with the development and progression of a wide variety of cancers. Colon cancer is one of the most common malignancies worldwide. A recent study demonstrated the upregulated expression of circPIP5K1A in non-small cell lung cancer. However, few studies have investigated the relationship between circ_0014130 level and colon cancer. Therefore, elucidating the underlying mechanisms of circPIP5K1A’s role may help with the identification of novel diagnostic and therapeutic targets for colon cancer. AIM To investigate the status of circPIP5K1A in colon cancers and its effects on the modulation of cancer development. METHODS The expression level of circPIP5K1A in tissue and serum samples from colon cancer patients, as well as human colonic cancer cell lines was detected by realtime quantitative reverse transcription-polymerase chain reaction. Following the transfection of specifically synthesized small interfering RNA (siRNA) into colon cell lines, we used Hoechst staining assay to measure the ratio of cell death in the absence of circPIP5K1A. Moreover, we also used the Transwell assay to assess the migratory function of colon cells overexpressing circPIP5K1A. Additionally, we employed a series of bioinformatics prediction programs to predict the potential of circPIP5K1A-targeted miRNAs and mRNAs. The miR-1273a vector was constructed, and then transfected with or without circPIP5K1A vector into colon cancer cells. Afterwards, the expression of activator protein 1 (AP-1), interferon regulating factor 4 (IRF-4), caudal type homeobox 2 (CDX-2), and zinc finger of the cerebellum 1 (Zic-1) was detected by western blotting. RESULTS CircPIP5K1A was significantly upregulated in colon cancer tissue relative to their adjacent normal tissues. Knockdown of circPIP5K1A in colon cancer cells impaired cell viability and suppressed cell invasion and migration, while enforced expression of circPIP5K1A exhibited the opposite effects on cell migration. Bioinformatics prediction program predicted that the association of circPIP5K1A with miR-1273a, as well as AP-1, IRF-4, CDX-2, and Zic-1. Subsequent studies showed that overexpression of circPIP5K1A augmented the expression of AP-1 but attenuated the expression of IRF-4, CDX-2, and Zic-1. Reciprocally, overexpression of miR-1273a abrogated the oncogenic function of circPIP5K1A in colon cancers. CONCLUSION Overall, our data demonstrate the oncogenic role of circPIP5K1A-miR-1273a axis in regulation of colon cancer development, which provides a novel insights into colon cancer pathogenesis. | Qu Zhang Chi Zhang Jian-Xin Ma Hui Ren Yu Sun Jiao-Zhen Xu | 2019 | World Journal of Gastroenterology2019，25，35： | 18 |
| 3 | Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers. | Rui Chen Shancheng Ren 无 Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun | 2014 | Asian Journal of Urology2014，1，1： | 13 |
| 4 | Reduced graphene oxide-nano zero value iron(rGO-nZVI) micro-electrolysis accelerating Cr(Ⅵ) removal in aquifer显示文摘Nanoscale zero-valent iron(nZVI) assembled on graphene oxide(GO)(rGO-nZVI) composites were synthesized by reduction of GO and ferrous ions with potassium borohydride,for use in Cr(VI) removal from aqueous solution.The results showed that the two-dimensional structure of GO could provide a skeleton support for Fe^0,thus overcoming the bottleneck of aggregation for nZVI.Also,rGO-nZVI would form a ferric-carbon micro-electrolysis system in Cr(VI)-contaminated aquifers,enhancing and accelerating electron transfer,exhibiting high rate and capacity for Cr(VI) removal.The optimum dosage of the applied r GO-nZVI was linearly correlated with the initial Cr(VI) concentration.Characterization of rGO-nZVI before and after reaction with Cr(VI) revealed the process of Cr(VI) removal:r GO-nZVI firstly transferred electrons from Fe^0 cores via their Fe(II)/Fe(III) shells to the GO sheet;there,negatively charged Cr(VI) received electrons and changed into positively charged Cr(III),which was adsorbed by the negatively charged GO sheet,avoiding the capping and passivating of nZVI.rGO-nZVI formed a good electrically conductive network,and thus had long-term electron releasing properties,which was important for groundwater remediation. | Liming Ren Jun Dong Zifang Chi Huazheng Huang | 2018 | Journal of Environmental Sciences2018，30，11： | 12 |

| 6 | Indirectly extruded biodegradable Zn-0.05wt%Mg alloy with improved strength and ductility: In vitro and in vivo studies显示文摘As compared to permanent orthopedic implants for load-bearing applications, biodegradable orthopedic implants have the advantage of no need for removing after healing, but they suffer from the 'trilemma' problem of compromising among sufficiently high mechanical properties, good biocompatibility and proper degradation rate conforming to the growth rate of new bones. In the present work, in vitro and in vivo studies of a Zn-0.05 wt%Mg alloy(namely, Zn-0.05 Mg alloy) were conducted with pure Zn as a control. The Zn-0.05 Mg alloy is composed of a small amount of Mg_2 Zn11 phase embedded in the refined Zn matrix with an average grain size of ~20 μm. The addition of 0.05 wt% Mg into Zn significantly increases the ultimate tensile strength up to 225 MPa and the elongation to fracture to 26%, but has little influence on the in vitro degradation rate. Both Zn and Zn-0.05 Mg alloy exhibit homogeneous in vitro degradation with a rate of about 0.15 mm/year. Based on the cytotoxicity evaluation, Zn and Zn-0.05 Mg alloy do not induce toxicity to L-929 cells, indicating that they have little toxicity to the general functions of the animal. An in vivo biocompatibility study of Zn and Zn-0.05 Mg alloy samples by placing them in a rabbit model for 4.12 and 24 weeks, respectively did not show any inflammatory cells, and demonstrated that new bone tissue formed at the bone/implant interface, suggesting that Zn and Zn-0.05 Mg alloy promote the formation of new bone tissue. The in vivo degradation of Zn and Zn-0.05 Mg alloy does not bring harm to the important organs and their cell structures. More interestingly, Zn and Zn-0.05 Mg alloy exhibit strong antibacterial activity against Escherichia coli and Staphylococcus aureus. The above results clearly demonstrate that the Zn-0.05 Mg alloy could be a potential biodegradable orthopedic implant material. | Chi Xiao Liqing Wang Yuping Ren Shineng Sun Erlin Zhang Chongnan Yan Qi Liu Xiaogang Sun Fenyong Shou Jingzhu Duan Huang Wang Gaowu Qin | 2018 | Journal of Materials Science & Technology2018，34，9： | 11 |

| 8 | Kindlin-2 expression in adult tissues correlates with their embryonic origins显示文摘Kindlin-2 functions in the maintenance of homeostasis and in human diseases.This study investigated the interrelationship between Kindlin-2 expression in tissues and the corresponding germ layers from which these tissues originated.Kindlin-2 expression was examined in normal adult human organs and human cancer tissues by immunohistochemical analyses.Analysis of Kindlin-2 mRNA levels in adult human organs in the Oncomine dataset revealed Kindlin-2 is highly expressed in mesoderm-derived organs.However,Kindlin-2 was negative or weakly expressed in endoderm/ectoderm-derived organs.Interestingly,the abnormal expression of Kindlin-2 was observed in a variety of human cancers.In agreement with its expression profile in humans,Kindlin-2 was also highly expressed in mesoderm-derived organs in mouse embryos with the exception of strong Kindlin-2 expression in ectoderm-derived spinal cord and ganglia,tissues that are highly mobile during embryonic development.Importantly,we demonstrated the expression level of Kindlin-2 in adult organs correlated with their embryonic dermal origins and deregulation of Kindlin-2 in tissues is associated with tumor progression.This finding will help us understand the dual role of Kindlin-2 in the regulation of tumor progression and embryonic development. | ZHAN Jun YANG Mei CHI XiaoChun ZHANG Jing PEI XueLian REN CaiXia GUO YongQing LIU Wei ZHANG HongQuan | 2014 | Science China(Life Sciences)2014，57，7： | 8 |
| 9 | An-Luo-Hua-Xian Pill Improves the Regression of Liver Fibrosis in Chronic Hepatitis B Patients Treated with Entecavir显示文摘Background and Aims:Chronic hepatitis B(CHB)can cause liver fibrosis and lead to cirrhosis and cancer.As the effectiveness of antiviral therapy to reverse liver fibrosis is limited,We aimed to evaluate the effect of An-Luo-Hua-Xian pill(ALHX)on fibrosis regression in CHB patients treated with entecavir(ETV).Methods:Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX(ETV+ALHX)between October 1,2013 and December 31,2020.Demographic,laboratory,and liver histology data before and after 78 weeks of treatment were collected.The Ishak fibrosis score(F)was used and fibrosis regression required a decrease in F of≥1 after treatment.Results:A total of 780 patients were enrolled,and 394 with a second liver biopsy after treatment were included in the per-protocol population,132 in ETV group and 262 in ETV+ALHX group.After 78 weeks of treatment,the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients:124/211(58.8%)vs.45/98(45.9%),p=0.035.The percentage of patients with a decreased liver stiffness measurement(LSM)was higher in the ETV+ALHX group:156/211(73.9%)vs.62/98(63.%),p=0.056.Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression[odds ratio(OR)=1.94,p=0.018],and a family history of hepatocellular carcinoma was on the contrary.(OR=0.41,p=0.031).Conclusions:ETV combined with ALHX increased liver fibrosis regression in CHB patients. | Yi-Qi Liu Chi Zhang Jia-Wen Li Li-Hua Cao Zhan-Qing Zhang Wei-Feng Zhao Qing-Hua Shang Da-Zhi Zhang An-Lin Ma Qing Xie Hong-Lian Gui Guo Zhang Ying-Xia Liu Jia Shang Shi-Bin Xie Jun Li Xu-Qing Zhang Zhi-Qiang Zou Yu-Ping Chen Zong Zhang Ming-Xiang Zhang Jun Cheng Fu-Chun Zhang Li-Hua Huang Jia-Bin Li Qing-Hua Meng Hai-Bin Yu Yu-Qiang Mi Yan-Zhong Peng Zhi-Jin Wang Li-Ming Chen Fan-Ping Meng Wan-Hua Ren Lang Bai Yi-Lan Zeng Rong Fan Xian-Zhi Lou Wei-Feng Liang Hui Liu Hui Zhuang Hong Zhao Gui-Qiang Wang | 2023 | Journal of Clinical and Translational Hepatology2023，11，2： | 7 |
| 10 | Global methane and nitrous oxide emissions from terrestrial ecosystems due to multiple environmental changes显示文摘Greenhouse gas(GHG)-induced climate change is among the most pressing sustainability challenges facing humanity today,posing serious risks for ecosystem health.Methane(CH_(4))and nitrous oxide(N_(2)O)are the two most important GHGs after carbon dioxide(CO_(2)),but their regional and global budgets are not well known.In this study,we applied a process-based coupled biogeochemical model to concurrently estimate the magnitude and spatial and temporal patterns of CH_(4)and N_(2)O fluxes as driven by multiple environmental changes,including climate variability,rising atmospheric CO_(2),increasing nitrogen deposition,tropospheric ozone pollution,land use change,and nitrogen fertilizer use.The estimated CH_(4)and N_(2)O emissions from global land ecosystems during 1981-2010 were 144.39±12.90 Tg C/yr(mean 62 SE;1 Tg=1012 g)and 12.52±0.74 Tg N/yr,respectively.Our simulations indicated a significant(P,0.01)annually increasing trend for CH_(4)(0.43±0.06 Tg C/yr)and N_(2)O(0.14±0.02 Tg N/yr)in the study period.CH_(4)and N_(2)O emissions increased significantly in most climatic zones and continents,especially in the tropical regions and Asia.The most rapid increase in CH_(4)emission was found in natural wetlands and rice fields due to increased rice cultivation area and climate warming.N_(2)O emission increased substantially in all the biome types and the largest increase occurred in upland crops due to increasing air temperature and nitrogen fertilizer use.Clearly,the three major GHGs(CH_(4),N_(2)O,and CO_(2))should be simultaneously considered when evaluating if a policy is effective to mitigate climate change. | Hanqin Tian Guangsheng Chen Chaoqun Lu Xiaofeng Xu Wei Ren Bowen Zhang Kamaljit Banger Bo Tao Shufen Pan Mingliang Liu Chi Zhang Lori Bruhwiler Steven Wofsy | 2015 | Ecosystem Health and Sustainability2015，1，1： | 7 |

Here we describe ethynyl deoxyuridine (EdU) as a biomarker for the assessment of cell proliferation and clearly demonstrate the feasibility of the EdU-labelling method for use in HCS assays. EdU detection is highly robust, reproducible, technically simple, and well suited for automated segmentation, which provides an excellent al- ternative for setting up multiplexed HCS assays of siRNA, miRNA and small-molecule libraries. | CHEN MiaoJuan QU DeZhong CHI WeiLin WANG Wei REN XiaoShuai CONG ShuJie LIANG PeiZhou FENG ShiPeng ZHANG BiLiang | 2011 | Science China Chemistry2011，54，11： | 6 |

| 13 | Notch pathway inhibitor DAPT enhances Atoh1 activity to generate new hair cells in situ in rat cochleae显示文摘Atoh1 overexpression in cochlear epithelium induces new hair cell formation. Use of adenovirus-mediated Atoh1 overexpression has mainly focused on the rat lesser epithelial ridge and induces ectopic hair cell regeneration. The sensory region of rat cochlea is difficult to transfect, thus new hair cells are rarely produced in situ in rat cochlear explants. After culturing rat cochleae in medium containing 10% fetal bovine serum, adenovirus successfully infected the sensory region as the width of the supporting cell area was significantly increased. Adenovirus encoding Atoh1 infected the sensory region and induced hair cell formation in situ. Combined application of the Notch inhibitor DAPT and Atoh1 increased the Atoh1 expression level and decreased hes1 and hes5 levels, further promoting hair cell generation. Our results demonstrate that DAPT enhances Atoh1 activity to promote hair cell regeneration in rat cochlear sensory epithelium in vitro. | Wen-wei Luo Zhao Han Dong-dong Ren Xin-wei Wang Fang-lu Chi Juan-mei Yang | 2017 | Neural Regeneration Research2017，12，12： | 6 |
| 14 | Severe human infection with a novel avian-origin influenza A(H7N4) virus显示文摘Human infections with influenza H7 subtypes, such as H7N9, have raised concerns worldwide. Here, we report a human infection with a novel influenza A(H7N4) virus. A 68 years-old woman with cardiovascular and cholecystic comorbidities developed rapidly progressed pneumonia with influenza-like-illness as initial symptom, recovered after 23 days-hospitalization including 8 days in ICU. Laboratory indicators for liver and blood coagulation dysfunction were observed. Oseltamivir phosphate, glucocorticoids and antibiotics were jointly implemented, with nasal catheterization of oxygen inhalation for this patient.We obtained the medical records and collected serial respiratory and blood specimens from her. We collected throat, cloacal and/or feces samples of poultry and wild birds from the patient's backyard, neighborhood, local live poultry markets(LPMs) and the nearest lake. All close contacts of the patient were followed up and sampled with throat swabs and sera. Influenza viruses and other respiratory pathogens were tested by real-time RT-PCR, viral culturing and/or sequencing for human respiratory and bird samples. Micro-neutralizing assay was performed for sera. A novel reassortant wild bird-origin H7N4 virus is identified from the patient and her backyard poultry(chickens and ducks) by sequencing, which is distinct from previously-reported avian H7N4 and H7N9 viruses. At least four folds increase of neutralizing antibodies to H7N4 was detected in her convalescent sera. No samples from close contacts, wild birds or other poultry were tested positive for H7N4 by real-time RT-PCR. | Xiang Huo Lun-biao Cui Cong Chen Dayan Wang Xian Qi Ming-hao Zhou Xiling Guo Fengming Wang William J.

| 16 | Comparative analysis of four essential Gracilariaceae species in China based on whole transcriptomic sequencing显示文摘Three Gracilaria species,G.chouae,G.blodgettii,G.vermiculophylla and a close relative species,Gracilariopsis lemaneiformis which is now nominated as Gracilaria lemaneiformis,are the typically indigenous species which are important resources for the production of special proteins,phycobilisomes,special carbohydrates,and agar in China.In this study,de novo transcriptome sequencing on these four species using the next generation sequencing technology was performed for the first time.Functional annotations on assembled sequencing reads showed that the transcriptomic profiles were quite different between G.lemaneiformis and other three Gracilaria species.Comparative analysis of differential gene expression related to carbohydrate and phycobiliprotein metabolisms also showed that the expression profiles of these essential genes were different in four species.The genes encoding allophycocyanin,phycocyanin and phycoerythrin were further examined in four species and their deduced amino acid sequences were used for phylogenetic analysis to confirm that G.lemaneiformis had close relationship to genus Gracilaria,as well as that within genus Gracilaria,G.chouae had closer relationship to G.vermiculophylla rather than to G.blodgettii.The de novo transcriptome study on four species provided a valuable genomic resource for further understanding and analysis on biological and evolutionary study among marine algae. | XU Jiayue SUN Jing YIN Jinlong WANG Liang WANG Xumin LIU Tao CHI Shan LIU Cui REN Lufeng WU Shuangxiu YU Jun | 2014 | Acta Oceanologica Sinica2014，33，2： | 3 |
| 17 | ATP regulates the phosphorylation and degradation of myofibrillar proteins in ground ovine muscle显示文摘Phosphorylation post-translational modification plays an important role in postmortem muscle quality traits. Adenosine triphosphate(ATP) is an energy source and a key substrate of phosphorylation which provides the phosphatase groups to proteins in the presence of protein kinases. However, in postmortem muscle, the effects of ATP content on phosphorylation are poorly studied. The study investigated the effect of ATP on protein phosphorylation and degradation in postmortem ovine muscle. The ground muscle with/without additional ATP were treated/control groups and stored at 25 and 4℃, respectively. The ATP content led to different changes of p H value between the ATP-treated and control groups. The phosphorylation level of myofibrillar proteins was higher(P<0.05) in ATP-treated group compared to the control group at both temperatures, which suggested that ATP played a vital role in postmortem protein phosphorylation. A slower degradation rate of μ-calpain, desmin and troponin T was observed in the ATP-treated group which showed that there was a negative relationship between ATP level and the degradation of proteins. These observations clearly highlighted the role of ATP on the development of meat quality by regulating the phosphorylation and degradation of myofibrillar proteins in postmortem ovine muscle. | REN Chi HOU Cheng-li ZHANG De-quan LI Xin XIAO Xiong BAI Yu-qiang | 2021 | Journal of Integrative Agriculture2021，20，1： | 2 |

| 19 | Transcriptome-wide evolutionary analysis on essential brown algae(Phaeophyceae)in China显示文摘Brown algae(Chromista,Ochrophyta,Phaeophyceae) are a large group of multicellular algae that play important roles in the ocean's ecosystem and biodiversity.However,poor molecular bases for studying their phylogenetic evolutions and novel metabolic characteristics have hampered progress in the field.In this study,we sequenced the de novo transcriptome of 18 major species of brown algae in China,covering six orders and seven families,using the high-throughput sequencing platform Illumina HiSeq 2000.From the transcriptome data of these 18 species and publicly available genome data of Ectocarpus siliculosus and Phaeodactylum tricornutum,we identified 108 nuclear-generated orthologous genes and clarified the phylogenetic relationships among these brown algae based on a multigene method.These brown algae could be separated into two clades: Clade Ishigeales-Dictyotales and Clade Ectocarpales-Laminariales-Desmarestiale-Fucales.The former was at the base of the phylogenetic tree,indicating its early divergence,while the latter was divided into two branches,with Order Fucales diverging from Orders Ectocarpales,Laminariales,and Desmarestiale.In our analysis of taxonomy-contentious species,Sargassum fusiforme and Saccharina sculpera were found to be closely related to genera Sargassum and Saccharina,respectively,while Petalonia fascia showed possible relation to genus Scytosiphon.The study provided molecular evidence for the phylogenetic taxonomy of brown algae. | SUN Jing WANG Liang WU Shuangxiu WANG Xumin XIAO Jingfa CHI Shan LIU Cui REN Lufeng ZHAO Yuhui LIU Tao YU Jun | 2014 | Acta Oceanologica Sinica2014，33，2： | 2 |
| 20 | Shrinkage of ipsilateral taste buds and hyperplasia of contralateral taste buds following chorda tympani nerve transection显示文摘The morphological changes that occur in the taste buds after denervation are not well understood in rats, especially in the contralateral tongue epithelium. In this study, we investigated the time course of morphological changes in the taste buds following unilateral nerve transection. The role of the trigeminal component of the lingual nerve in maintaining the structural integrity of the taste buds was also examined. Twenty-four Sprague-Dawley rats were randomly divided into three groups: control, unilateral chorda tympani nerve transection and unilateral chorda tympani nerve transection + lingual nerve transection. Rats were allowed up to 42 days of recovery before being euthanized. The taste buds were visualized using a cytokeratin 8 antibody. Taste bud counts, volumes and taste receptor cell numbers were quantified and compared among groups. No significant difference was detected between the chorda tympani nerve transection and chorda tympani nerve transection + lingual nerve transection groups. Taste bud counts, volumes and taste receptor cell numbers on the ipsilateral side all decreased significantly compared with control. On the contralateral side, the number of taste buds remained unchanged over time, but they were larger, and taste receptor cells were more numerous postoperatively. There was no evidence for a role of the trigeminal branch of the lingual nerve in maintaining the structural integrity of the anterior taste buds. | Yi-ke Li Juan-mei Yang Yi-bo Huang Dong-dong Ren Fang-lu Chi | 2015 | Neural Regeneration Research2015，10，6： | 2 |
