| 3 | Disease profile and plasma neutralizing activity of postvaccination Omicron BA.1 infection in Tianjin,China:a retrospective study显示文摘Dear Editor,SARS-CoV-2 Omicron variant BA.1 first emerged on the Chinese mainland on January 8,2022,in Tianjin and caused a large wave of infections.1 Four rounds of mass testing of its~14 million residents were launched on January 9,12,15,and 20,respectively.As of February 7,2022,a total of 430 individuals were tested positive for Omicron BA.1,with no new infections detected for the following 16 days.In the Chinese mainland,the most delivered vaccines are inactivated vaccines.As of January 8,2022,up to 93.2%of Tianjin’s residents had been vaccinated with at least one dose.2 We investigated the protection conferred by vaccination against Omicron BA.1 by examining the breakthrough infections among vaccinees as compared with unvaccinated cases.Our study population comprised all 430 cases during the outbreak of Omicron BA.1 in Tianjin. | Hong Zheng Yunlong Cao Xiaosu Chen Fengmei Wang Ye Hu Weiliang Song Yangyang Chai Qingqing Gu Yansong Shi Yingmei Feng Shuxun Liu Yan Xie Xiaoliang Sunney Xie Wentao Jiang Zhongyang Shen | 2022 | Cell Research2022，32，8： | 12 |
| 4 | Authentic compound-free strategy for simultaneous determination of primary coumarins in Peucedani Radix using offline high performance liquid chromatography–nuclear magnetic resonance spectroscopy–tandem mass spectrometry显示文摘Herein, a strategy is proposed for the simultaneous determination of primary coumarins in Peucedani Radix(Chinese name: Qianhu). The methodology consists of three consecutive steps: 1) Semi-preparative LC in combination with a home-made automated fraction collection module to fragment the universal metabolome standard into ten fractions(Frs. I–X); 2) LC–accurate MS/MS and quantitative1 H NMR spectroscopy conducted in parallel to acquire the qualitative and quantitative data of each fraction; 3) Robust identification and quantification of components by use of LC coupled to multiple reaction monitoring. In this final step, the most significant fractions(Frs. III–X) were pooled to serve as the pseudo-mixed standard solution. Meticulous online parameter optimization was performed to obtain the optimal parameters, including ion transitions and collision energies. Concerns were particularly paid onto pursuing the parameters being capable of monitoring regiospecific isomers, notably praeruptorin E vs. 3′-isovaleryl-4′-angeloylkhellactone. The quantitative performance of the method was validated according to diverse assays. Eleven primary coumarins(1–11) were unambiguously identified and absolutely quantified, even though no external reference compound was used. Above all, the integrated strategy not only provides a feasible pipeline for the quality assessment of Peucedani Radix, but more importantly, shows the potential for authentic compound-free quantitative evaluation of traditional Chinese medicines. | Yao Liu Qingqing Song Wenjing Liu Peng Li Jun Li Yunfang Zhao Liang Zhang Pengfei Tu Yitao Wang Yuelin Song | 2018 | Acta Pharmaceutica Sinica B2018，8，4： | 6 |
| 5 | Deciphering primate retinal aging at single-cell resolution显示文摘Dear Editor, The retina is a light-sensitive highly-organized tissue,which is vulnerable to aging and age-related retinal diseases.Specifically,progressive retinal degeneration leads to visual function deterioration and vision impairment in the elderly(Lin et al.,2016).In diseases such as age-related macular degeneration(AMD),retinitis pigmentosa(RP)and diabetic retinopathy(DR),pathological process lacking effective treatments profoundly and negatively impact on the quality of life in the elderly(Lin et al.,2016;Chen et al.,2019).Thus,an in-depth molecular assessment of the mechanisms driv-ing retinal aging is of urgent scientific and medical importance. | Si Wang Yuxuan Zheng Qingqing Li Xiaojuan He Ruotong Ren Weiqi Zhang Moshi Song Huifang Hu Feifei Liu Guoqiang Sun Shuhui Sun Zunpeng Liu Yang Yu Piu Chan Guo-Guang Zhao Qi Zhou Guang-Hui Liu Fuchou Tang Jing Qu | 2021 | Protein & Cell2021，12，11： | 4 |
| 6 | Dual activated NIR-Ⅱ fluorescence and photoacoustic imaging-guided cancer chemo-radiotherapy using hybrid plasmonic-fluorescent assemblies显示文摘Multimodal imaging in the second near-infrared window(NIR-II)guided cancer therapy is a highly precise and efficient cancer theranostic strategy.However,it is still a challenge to develop activated NIR-II optical imaging and therapy agents.In this study,we develop a pH-responsive hybrid plasmonic-fluorescent vesicle by self-assembly of amphiphilic plasmonic nanogapped gold nanorod(AuNNR)and fluorescent down-conversion nanoparticles(DCNP)(AuNNR-DCNP Ve),showing remarkable and activated NIR-II fluorescence(FL)/NIR-II photoacoustic(PA)imaging performances.The hybrid vesicle also exhibited superior loading capacity of doxorubicin as a superior drug carrier and efficient radiosensitizer for X-ray-induced radiotherapy.Interestingly,the accumulated hybrid AuNNR-DCNP Ve in the tumor resulted in a recovery of NIR-II FL imaging signal and a variation in NIR-II PA imaging signal.Dual activated NIR-II PA and FL imaging of the hybrid vesicle could trace drug release and precisely guided cancer radiotherapy to ultimately reduce the side effects to healthy tissue. | Tao Chen Lichao Su Xiaoguang Ge Wenmin Zhang Qingqing Li Xuan Zhang Jiamin Ye Lisen Lin Jibin Song Huanghao Yang | 2020 | Nano Research2020，13，12： | 4 |
| 7 | A New Indicator for Global Food Security Assessment: Harvested Area Rather Than Cropland Area显示文摘Cropland area has long been used as a key indicator of food security.However,grain yield is not solely controlled by the area of the cropland.Therefore,we proposed a new indicator to assess food security.Results show that from 1992 to 2004,the global cropland area increased by 840200 km^(2)(99.4%),but the grain yield increased only by 310 million t(29.1%);and from 2004 to 2015,the cropland area decreased by 39000 km^(2)(4.64%),but the grain yield increased by 370 million t(70.84%).This result showed that grain yield was not linearly correlated with cropland area,and delimiting the threshold of cropland protection may not guarantee food security.Combined with further correlation analysis,we found that the increase in the global grain yield was more closely related to the harvested area(R^(2)=0.94),which indicated that the harvested area is a more scientific and accurate indicator than cropland area in terms of guaranteeing food security.Therefore,if governments want to ensure the food security,they should choose a new and more accurate indicator:harvested area rather than cropland area. | SONG Fengjiao WANG Shijie BAI Xiaoyong WU Luhua WANG Jinfeng LI Chaojun CHEN Huan LUO Xuling XI Huipeng ZHANG Sirui LUO Guofeng YAN Mengqi ZHEN Qingqing | 2022 | Chinese Geographical Science2022，32，2： | 2 |
| 8 | Preferentially released miR-122 from cyclodextrin-based star copolymer nanoparticle enhances hepatoma chemotherapy by apoptosis induction and cytotoxics efflux inhibition显示文摘Chemotherapy,as one of the most commonly used treatment modalities for cancer therapy,provides limited benefits to hepatoma patients,owing to its inefficient delivery as well as the intrinsic chemo-resistance of hepatoma.Bioinformatic analysis identified the therapeutic role of a liver-specific microRNA-miR-122 for enhancing chemo-therapeutic efficacy in hepatoma.Herein,a cyclodextrin-cored star copolymer nanoparticle system(sCDP/DOX/miR-122)is constructed to co-deliver miR-122 with doxorubicin(DOX)for hepatoma therapy.In this nanosystem,miR-122 is condensed by the outer cationic poly(2-(dimethylamino)ethyl methacrylate)chains of sCDP while DOX is accommodated in the inner hydrophobic cyclodextrin cavities,endowing a sequential release manner of miR-122 and DOX.The preferentially released miR-122 not only directly induces cell apoptosis by down regulation of Bcl-w and enhanced p53 activity,but also increases DOX accumulation through inhibiting cytotoxic efflux transporter expression,which realizes synergistic performance on cell inhibition.Moreover,sCDP/DOX/miR-122 displays remarkably increased anti-tumor efficacy in vivo compared to free DOX and sCDP/DOX alone,indicating its great promising in hepatoma therapy. | Qingqing Xiong Yang Bai Run Shi Jian Wang Weiguo Xu Mingming Zhang Tianqiang Song | 2021 | Bioactive Materials2021，6，11： | 2 |
| 9 | Ultrasound-propelled Janus Au NR-mSiO_(2) nanomotor for NIR-II photoacoustic imaging guided sonodynamic-gas therapy of large tumors显示文摘Varieties of contrast agents have been developed for photoacoustic(PA)and ultrasound(US)imaging of cancers in vivo.However,access of traditional contrast agents into the sites of tumors has been principally through passive infiltration without any external force,preventing their deep penetration into the tissues of the tumors,and hindering the use of PA and US for deep tumor imaging.The concept of micro/nanomotors has been the focus of increasing attention as active theranostic agents due to their active movement in particular fluids,thereby conducting assigned tasks.Herein,US-propelled Janus mesoporous SiO_(2)partially coated gold nanorods(Au NR-mSiO_(2))were fabricated for deep tumor NIR-II PA imaging and synergistic sonodynamic-gas therapy.Following US irradiation,2,2-azobis[2-(2-imidazolin-2-yl)propane]dihydrochloride(AIPH)loaded in mSiO_(2)(Au NR-mSiO_(2)/AIPH)generated N_(2)microbubbles with high efficiency to achieve nanomotor drive.Due to the deep penetration of US,the nanomotors exhibited a capability to travel deep within sites of tumors,providing enhanced PA/US imaging inside the tumors.Furthermore,the nanomotor based cancer therapy was demonstrated through synergistic N_(2)gas and sonodynamic therapy.The US-propelled nanomotors demonstrated a novel strategy for the simultaneous PA/US dual imaging deep within tumor tissues and precise therapy of large tumors. | Jiamin Ye Qinrui Fu Luntao Liu Lanlan Chen Xuan Zhang Qingqing Li Zhi Li Lichao Su Rong Zhu Jibin Song Huanghao Yang | 2021 | Science China Chemistry2021，64，12： | 2 |
| 10 | Fast screening compositions of PM2.5 by ATR-FTIR: Comparison with results from IC and OC/EC analyzers显示文摘Chemical speciation of fine particles or PM_(2.5) collected on filters is still a costly and timeconsuming task. In this study, filter-based PM_(2.5) samples were collected during November–December 2013 at four sites in Guangzhou, and the major components were fast screened(~7 min per filter sample) by Attenuated Total Reflectance(ATR)-Fourier Transform Infrared Spectroscopic(FTIR) in comparison with that measured by Organic carbon/Element carbon(OC/EC) analyzer and Ion Chromatography(IC). The concentrations of nitrate, ammonium, sulfate,primary organic carbon(POC) and secondary organic carbon(SOC) measured by OC/EC and IC analyzers were better correlated with their infrared absorption peak heights at 1320 cm^(-1) for nitrate, 1435, 3045 and 3215 cm^(-1) for ammonium, 615 cm^(-1) for sulfate, 690, 760 and 890 cm^(-1) for POC and 1640 and 1660 cm^(-1) for SOC respectively, during polluted days(PM_(2.5)> 75 μg/m^3) than during clean days(PM_(2.5)≤ 75 μg/m^3). With the evolution of a haze episode during our field campaign, the concentrations of the major PM_(2.5) components displayed consistent variations with their infrared absorption peak heights, suggesting ATR-FTIR could be a fast and useful technique to characterize filter-based PM_(2.5) compositions particularly during pollution events although cautions should be taken when PM_(2.5) levels are low. Notably, elevated PM_(2.5) mass concentrations occurred with enhanced ratios of [NO_(-3)]/[SO_4^(2-)] and [NH^(+4)]/[SO_4^(2-)], implying that nitrogenous components play vital roles in the PM_(2.5) pollution events in the study region. | Xu Yu Wei Song Qingqing Yu Sheng Li Ming Zhu Yanli Zhang Wei Deng Weiqiang Yang Zhonghui Huang Xinhui Bi Xinming Wang | 2018 | Journal of Environmental Sciences2018，30，9： | 2 |
| 11 | Synthesis and characterization of caprolactone based polyurethane with degradable and antifouling performance显示文摘In this work,a degradable polyurethane composed of caprolactone(CL)and L-Lactide(LLA)as soft segments,and 4,40-methylenebis(cyclohexyl isocyanate)(H12 MDI)and polytetramethylene ether glycol(PTMEG)as hard segments,was prepared.Hydrolytic degradation experiment revealed that the degradable polyurethane(PU)could be degraded in artificial seawater.It also showed that caprolactone-copolyurethane(CL-PU)copolymer with higher crystallinity degraded much slower in artificial seawater.However,the introduction of LLA resulted in an increase in the hydrophilicity and reduction in the crystallinity of degradable PU,as demonstrated by the contact angle analysis.The result of the scanning electron microscope showed that the surface of degradable PU renewed under static condition.Moreover,degradable PU was able to be used as a carrier,and it controlled the release rate of 4,5-dichloro-2-octyl-isothiazolone(DCOIT).The anti-diatom(Navicula incerta)test demonstrated that the(caprolactone-co-L-lactide)-co-polyurethane 4(CL/LAx-PU4)with DCOIT contents prevented the adhesion of diatom Navicula incerta(88.37%reduction)due to their self-polishing and the release of antifoulants.Therefore,the degradable PU consisted of CL,LLA,and DCOIT could be a durable resin with good antifouling activity for the application in the marine anti-biofouling field. | Abid Ali Lina Song Jiankun Hu Jingxian Jiang Qingqing Rao Muhammad Shoaib Shah Fahad Yongjie Cai Xiaoli Zhan Fengqiu Chen Qinghua Zhang | 2021 | Chinese Journal of Chemical Engineering2021，34，6： | 2 |

| 13 | E3 ligase FBXW7 aggravates TMPD-induced systemic lupus erythematosus by promoting cell apoptosis显示文摘Systemic lupus erythematosus(SLE)is a systemic autoimmune disease,and the pathogenesis of SLE has not been fully elucidated.The E3 ubiquitin ligase FBXW7 has been well characterized in cancer as a tumor suppressor that can promote the ubiquitination and subsequent degradation of various oncoproteins;however,the potential role of FBXW7 in autoimmune diseases is unclear.In the present study,we identified that FBXW7 is a crucial exacerbating factor for SLE development and progression in a mouse model induced by 2,6,10,14-tetramethylpentadecane(TMPD).Myeloid cell-specific FBXW7-deficient(Lysm+FBXW7f/f)C57BL/6 mice showed decreased immune complex accumulation,glomerulonephritis,glomerular mesangial cell proliferation,and basemembrane thickness in the kidney.Lysm+FBXW7f/f mice produced fewer anti-Sm/RNP and anti-ANA autoantibodies and showed a decreased MHC II expression in B cells.In Lysm+FBXW7f/f mice,we observed that cell apoptosis was reduced and that fewer CD11b+Ly6Chi inflammatory monocytes were recruited to the peritoneal cavity.Consistently,diffuse pulmonary hemorrhage(DPH)was also decreased in Lysm+FBXW7f/f mice.Mechanistically,we clarified that FBXW7 promoted TMPD-induced cell apoptosis by catalyzing MCL1 degradation through K48-linked ubiquitination.Our work revealed that FBXW7 expression in myeloid cells played a crucial role in TMPD-induced SLE progression in mice,which may provide novel ideas and theoretical support for understanding the pathogenesis of SLE. | Zhenlu Chong Chunjing Bao Jia He Tianxiao Chen Lijia Zhong Gaopeng Li Huanle Li Lutong Fang Yinjing Song Guoxiang Fu Xuyan Yang Lihua Lai Yang Liu Qingqing Wang | 2018 | Cellular & Molecular Immunology2018，15，12： | 2 |
| 14 | Experimental investigation of the full coverage film cooling effectiveness of a turbine blade with shaped holes显示文摘The film cooling effectiveness of two turbine blades at different turbulence intensities(0.62%and 16.00%)and mass flux ratios(2.91%,5.82%,8.73%and 11.63%)is studied by using the Pressure-Sensitive Paint(PSP)measurement technique.There are a baseline and an improved turbine blade in current work,and their film cooling hole position distribution is the same.But the hole shape on suction surface and pressure surface is changed from cylindrical hole(baseline)to laid-back fan-shaped hole(improved blade).Both blades have 5 rows of cylindrical holes at the leading edge and 4 rows of cooling-holes on the suction surface and the pressure surface.The experimental results show that the film cooling effectiveness of the improved blade is much better than the baseline.The increase in turbulence intensity will reduce the cooling effectiveness on the surface of turbine blade,but the effect of turbulence intensity becomes weaker with an increase in the mass flux ratio.Compared with the multiple rows of cylindrical holes,the cooling effectiveness of shaped holes is more influenced by the turbulence intensity at low mass flux ratio. | Cunliang LIU Fan ZHANG Shuaiqi ZHANG Qingqing SHI Hui SONG | 2022 | Chinese Journal of Aeronautics2022，35，3： | 2 |
| 15 | Effect of Jianpi Bushen formula on aromatase-inhibitor-associated bone loss after menopause显示文摘OBJECTIVE: To investigate the effect of Jianpi Bushen(JPBS) formula on aromatase inhibitor(AI)-associated bone loss after menopause.METHODS: Six-month-old female rats were randomly divided into 6 groups: a sham group, an ovariectomized(OVX) group, an OVX treated with exemestane and 3 OVX groups each treated with a different dose of JPBS formula. Bone mineral density(BMD) at the lumbar vertebrae, histology, bone markers and serum levels of estrogen were assessed. Furthermore, a cohort study was conducted in 130 postmenopausal women with breast cancer that had undergone treatment with AIs. The subjects were given JPBS + caltrate D or caltrate D only, administered orally. BMD at the lumbar vertebrae and femoral neck and bone markers were evaluated in both control and herbal treatment groups at baseline and 12 months.RESULTS: Experimental results indicated that a high dose of JPBS significantly increased the trabecular bone area percentage(Tb.Ar %) and broadened the trabecular thickness(Tb.Th). The JPBS formula enriched the carboxyterrninal propeptide of type ipmcollagen and increased serum estrogen level significantly. The clinical investigation revealed that bone loss was decreased in the group treated with JPBS vs control(BMD T score at lumbar vertebrae, 3.9% increased vs 14.58% decreased, respectively, P = 0.004 and BMD T score on femoral neck, 1.8% decreased vs 22.45% decreased, respectively, P = 0.008). Besides, JPBS formula elevated Nmiddle osteocalcin and decreased type Ⅰ collagen cross-linked C-terminal telopeptide.CONCLUSION: JPBS formula prevented aromatase-inhibitor-associated bone loss after menopause by inhibiting bone resorption and promoting bone formation. | Dai Yan Chen Qingqing Guan Ruodan Xu Rui Qiu Chang Song Xue Guo Qianqian Wang Zhiyu Chen Qianjun | 2018 | Journal of Traditional Chinese Medicine2018，38，6： | 2 |

| 18 | Construction of high-efficient visible photoelectrocatalytic system for carbamazepine degradation:Kinetics,degradation pathway and mechanism显示文摘This study aimed to construct a photoelectrocatalytic(PEC)reaction system based on the self-made reduced TiO_(2) NTAs(r-TNAs)photoanode and activated carbon/Polytetrafluoroethylene(AC/PTFE)cathode.It would be observed clearly that the degradation rate constant of carbamazepine(CBZ)over r-TNAs(photoanode)-AC/PTFE(cathode)PEC system(0.04961 min^(-1))was even higher than that of r-TNAs(photoanode)-Pt(cathode)PEC system(0.04602 min^(-1))with the assistance of visible light irradiation and+0.4 V external potential.Besides,in order to obtain optimized conditions,the influence of key parameters such as pH value,electric current density and electrolyte concentration were studied.Most impo rtantly,photoelectrochemical(PECH)properties,reactive oxide species contribution.OH formation rate and CBZ degradation pathway were determined.The results illustrated that the excellent PEC degradation performance depended on the excellent photocatalytic property of r-TNAs photoanode and electron transfer prope rty of photoelectrodes in r-TNAs(photoanode)-AC/PTFE(cathode)PEC system.Therefo re,the study demonstrated that the r-TNAs(photoanode)-AC/PTFE(cathode)PEC system could be expected to replace metal-catalyzed cathodes depending on its excellent PEC performance activity and low cost as well as the reaction system possessed objective and practical application prospect. | Ruonan Guo Li-Chao Nengzi Ying Chen Qingqing Song Jianfeng Gou Xiuwen Cheng | 2020 | Chinese Chemical Letters2020，31，10： | 1 |
