| 1 | Entinostat,a classⅠselective histone deacetylase inhibitor,plus exemestane for Chinese patients with hormone receptor-positive advanced breast cancer:A multicenter,randomized,double-blind,placebo-controlled,phase 3 trial显示文摘Entinostat plus exemestane in hormone receptor-positive(HR+)advanced breast cancer(ABC)previously showed encouraging outcomes.This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR+ABC that relapsed/progressed after≥1 endocrine therapy.Patients were randomized(2:1)to oral exemestane 25 mg/day plus entinostat(n=235)or placebo(n=119)5 mg/week in 28-day cycles.The primary endpoint was the independent radiographic committee(IRC)-assessed progression-free survival(PFS).The median age was 52(range,28—75)years and 222(62.7%)patients were postmenopausal.CDK4/6 inhibitors and fulvestrant were previously used in 23(6.5%)and 92(26.0%)patients,respectively.The baseline characteristics were comparable between the entinostat and placebo groups.The median PFS was 6.32(95%CI,5.30—9.11)and 3.72(95%CI,1.91—5.49)months in the entinostat and placebo groups(HR,0.76;95%CI,0.58—0.98;P=0.046),respectively.Grade≥3 adverse events(AEs)occurred in 154(65.5%)patients in the entinostat group versus 23(19.3%)in the placebo group,and the most common grade≥3 treatment-related AEs were neutropenia[103(43.8%)],thrombocytopenia[20(8.5%)],and leucopenia[15(6.4%)].Entinostat plus exemestane significantly improved PFS compared with exemestane,with generally manageable toxicities in HR+ABC(ClinicalTrials.gov#NCT03538171). | Binghe Xu Qingyuan Zhang Xichun Hu Qing Li Tao Sun Wei Li Quchang Ouyang Jingfen Wang Zhongsheng Tong Min Yan Huiping Li Xiaohua Zeng Changping Shan Xian Wang Xi Yan Jian Zhang Yue Zhang Jiani Wang Liang Zhang Ying Lin Jifeng Feng Qianjun Chen Jian Huang Lu Zhang Lisong Yang Ying Tian Hongyan Shang | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 3 |
| 2 | Light-triggered nitric oxide release and structure transformation of peptide for enhanced intratumoral retention and sensitized photodynamic therapy显示文摘Tumor-targeted delivery of nanomedicine is of great importance to improve therapeutic efficacy of cancer and minimize systemic side effects.Unfortunately,nowadays the targeting efficiency of nanomedicine toward tumor is still quite limited and far from clinical requirements.In this work,we develop an innovative peptide-based nanoparticle to realize light-triggered nitric oxide(NO)release and structural transformation for enhanced intratumoral retention and simultaneously sensitizing photodynamic therapy(PDT).The designed nanoparticle is self-assembled from a chimeric peptide monomer,TPP-RRRKLVFFK-Ce6,which contains a photosensitive moiety(chlorin e6,Ce6),aβ-sheet-forming peptide domain(Lys-Leu-Val-Phe-Phe,KLVFF),an oligoarginine domain(RRR)as NO donor and a triphenylphosphonium(TPP)moiety for targeting mitochondria.When irradiated by light,the constructed nanoparticles undergo rapid structural transformation from nanosphere to nanorod,enabling to achieve a significantly higher intratumoral accumulation by 3.26 times compared to that without light irradiation.More importantly,the conversion of generated NO and reactive oxygen species(ROS)in a light-responsive way to peroxynitrite anions(ONOO)with higher cytotoxicity enables NO to sensitize PDT in cancer treatment.Both in vitro and in vivo studies demonstrate that NO sensitized PDT based on the well-designed transformable nanoparticles enables to eradicate tumors efficiently.The light-triggered transformable nanoplatform developed in this work provides a new strategy for enhanced intratumoral retention and improved therapeutic outcome. | Lingdong Jiang Danyang Chen Zhaokui Jin Chao Xia Qingqing Xu Mingjian Fan Yunlu Dai Jia Liu Yuanpei Li Qianjun He | 2022 | Bioactive Materials2022，7，6： | 3 |

| 4 | Determination of water content in corn stover silage using near-infrared spectroscopy显示文摘The aim of this study was to evaluate the feasibility of utilizing near-infrared spectroscopy to determine the water content of corn stover silage across a wide range.The water contents of 208 samples were measured,and their corresponding near-infrared spectra were simultaneously collected.The effects of different preprocessing methods,such as derivation,standard normal variety(SNV),multiplicative scatter correction(MSC),and non-preprocessing methods for the obtained near-infrared spectra on the performance of calibration models were compared.The calibration models were established by modified partial least squares(MPLS)regression.The results showed that the calibration model developed from the successive preprocessing of MSC and first-order derivation(1-D)achieved the optimal performance.The correlation coefficients of the calibration and validation subset were 0.974 and 0.949,respectively,and the standard errors of the calibration and cross validation were 4.249% and 4.256%,respectively.External validation was performed on 60 samples.The correlation coefficient between the measured and predicted values of the calibration model was 0.973 and the prediction model’s relative percent deviation was 4.317.This indicated that the mathematical model of near-infrared spectroscopy predicted the water content in corn stover silage with high accuracy.The study showed that the near-infrared spectroscopy technology can be used for rapid and non-destructive testing across a wide range of water contents in the corn stover silage. | Maoqun Zhang Chao Zhao Qianjun Shao Zidong Yang Xuefen Zhang Xiaofeng Xu Muhammad Hassan | 2019 | International Journal of Agricultural and Biological Engineering2019，12，6： | 2 |
| 5 | 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 |
| 6 | Sonocatalytic hydrogen/hole-combined therapy for anti-biofilm and infected diabetic wound healing显示文摘It is a great challenge to effectively eradicate biofilm and cure biofilm-infected diseases because dense extracellular polymeric substance matrix prevents routine antibacterial agents from penetrating into biofilm.H_(2)is an emerging energy-regulating molecule possessing both high biosafety and high tissue permeability.In this work,we propose a concept of sonocatalytic hydrogen/hole-combined’inside/outside-cooperation’anti-biofilm for promoting bacteria-infected diabetic wound healing based on two-dimensional piezoelectric nanomaterials.Proof-of-concept experiments using C_(3)N_(4)nanosheets as a representative piezoelectric catalyst with wide band gap and high biosafety have verified that sonocatalytically generated H_(2)and holes rapidly penetrate into biofilm to inhibit bacterial energy metabolism and oxidatively deprive polysaccharides/NADH in biofilm to destroy the bacterial membrane/electron transport chain,respectively,inside/outside-cooperatively eradicating biofilm.A bacteria-infected diabetic wound model is used to confirm the excellent in vivo antibacterial performance of sonocatalytic hydrogen/hole-combined therapy,remarkably improving bacteria-infe cted diabetic wound healing.The proposed strategy of sonocatalytic hole/hydrogen-combined’inside/outside-cooperation’will make a highway for treatment of deep-seated biofilm infection. | Qingqing Xu Shengqiang Chen Lingdong Jiang Chao Xia Lingting Zeng Xiaoqing Cai Zhaokui Jin Shucun Qin Wenjiang Ding Qianjun He | 2023 | National Science Review2023，10，5： | 2 |

| 15 | Engineering biocompatible TeSex nano-alloys as a versatile theranostic nanoplatform显示文摘Photothermal nanotheranostics, especially in the near infrared II(NIR-II) region, exhibits a great potential in precision and personalized medicine, owing to high tissue penetration of NIR-II light.NIR-II-photothermal nanoplatforms with high biocompatibility as well as high photothermal effect are urgently needed but rarely reported so far. Te nanomaterials possess high absorbance to NIR-II light but also exhibit high cytotoxicity, impeding their biomedical applications. In this work, the controllable incorporation of biocompatible Se into the lattice of Te nanostructures is proposed to intrinsically tune their inherent cytotoxicity and enhance their biocompatibility, developing TeSe_(x) nano-alloys as a new kind of theranostic nanoplatform. We have uncovered that the cytotoxicity of Te nanomaterials primarily derives from irreversible oxidation stress and intracellular imbalance of organization and energy, and can be eliminated by incorporating a moderate proportion of Se(x = 0.43). We have also discovered that the as-prepared TeSe_(x) nano-alloys have extraordinarily high NIR-II-photothermal conversion efficiency(77.2%),^(64)Cu coordination and computed tomography contrast capabilities, enabling high-efficacy multimodal photothermal/photoacoustic/positron emission tomography/computed tomography imaging-guided NIR-II-photothermal therapy of cancer. The proposed nano-alloying strategy provides a new route to improve the biocompatibility of biomedical nanoplatforms and endow them with versatile theranostic functions. | Xiang Ling Zhaokui Jin Qi Jiang Xiaotao Wang Bin Wei Zhongchang Wang Yangsen Xu Tianye Cao Jonathan W.Engle Weibo Cai Chenliang Su Qianjun He | 2021 | National Science Review2021，8，6： | 0 |

Results show that the thermal stresses concentration has been effectively reduced, and the distribution of the thermal deformations and thermal strains have also been relaxed and improved by transition layer of FGM. | Yilan Kang Qianjun Xu Shouwen Yu | 1998 | Chinese Science Bulletin1998，43，10： | 0 |
| 17 | Safety and Current Status of the COVID-19 Vaccine among Patients with Breast cancer: A Cross-Sectional Study from China显示文摘In this study,we aimed to explore the safety and vaccination coverage data of Chinese patients with breast cancer receiving coronavirus disease 2019(COVID-19)vaccination.The patients were recruited from 41 hospitals across 20 Chinese provinces.The vaccination coverage was approximately 22.4%,and the frequency of total adverse events was 13.3%after the first dose and 9.9%after the second dose.The most frequent adverse reaction within 14 days of the first dose was local pain(5.7%).Unvaccinated patients were very likely to reject the vaccine rather than be hesitant in patients with old age(odds ratio[OR],1.238;95%confidence interval[CI],1.101-1.391),chronic disease history(OR,1.189;95%CI,1.057-1.337),and cancer relapse(OR,1.398;95%CI,1.233-1.585).Of the unvaccinated patients with breast cancer,54.1%opted to receive COVID-19 vaccines if more data were available.Considering the safety but low vaccination coverage for breast cancer,increased positive attitudes and acceptance toward COVID-19 vaccines are important. | Shaohua Zhang Jianbin Li Ruonan Xu Qianjun Chen Gang Sun Ying Lin Feng Jin Xinlan Liu Zhimin Fan Yiding Chen Yali Cao Xinzheng Li Jianyun Nie Guiying Xu Xiaojia Wang Yuee Teng Tao Sun Hong Liu Jing Luo Cuizhi Geng Man Li Ting Luo Yinhua Liu Fu-Sheng Wang Zefei Jiang | 2023 | Infectious Diseases & Immunity2023，3，3： | 0 |
