| 1 | Machine learning aided design of perovskite oxide materials for photocatalytic water splitting显示文摘Suffering from the inefficient traditional trial-and-error methods and the huge searching space filled by millions of candidates, discovering new perovskite visible photocatalysts with higher hydrogen production rate(RH_(2)) still remains a challenge in the field of photocatalytic water splitting(PWS). Herein, we established structural-property models targeted to RH_(2) and the proper bandgap(Eg) via machine learning(ML) technology to accelerate the discovery of efficient perovskite photocatalysts for PWS. The Pearson correlation coefficients(R) of leave-one-out cross validation(LOOCV) were adopted to compare the performances of different algorithms including gradient boosting regression(GBR), support vector regression(SVR), backpropagation artificial neural network(BPANN), and random forest(RF). It was found that the BPANN model showed the highest R values from LOOCV and testing data of 0.9897 and 0.9740 for RH_(2),while the GBR model had the best values of 0.9290 and 0.9207 for Eg. Furtherly, 14 potential PWS perovskite candidates were screened out from 30,000 ABO3-type perovskite structures under the criteria of structural stability, Eg, conduction band energy, valence band energy and RH_(2). The average RH_(2) of these14 perovskites is 6.4% higher than the highest value in the training data set. Moreover, the online web servers were developed to share our prediction models, which could be accessible in http://gffzz63fbdfd3a8d8472dh5p0ofppbukqk66oo.ffgz.tsg.suse.edu.cn/ocpmdm/material_api/ahfga3d9puqlknig(E_g prediction) and http://gffzzb41aaebde6114c49h5p0ofppbukqk66oo.ffgz.tsg.suse.edu.cn/ocpmdm/material_api/i0 ucuyn3 wsd14940(RH_(2) prediction). | Qiuling Tao Tian Lu Ye Sheng Long Li Wencong Lu Minjie Li | 2021 | Journal of Energy Chemistry2021，30，9： | 5 |
| 2 | Protocatechuic aldehyde protects cardiomycoytes against ischemic injury via regulation of nuclear pyruvate kinase M2显示文摘Rescuing cells from stress damage emerges a potential therapeutic strategy to combat myocardial infarction.Protocatechuic aldehyde(PCA)is a major phenolic acid in Chinese herb Danshen(Salvia miltiorrhiza root).This study investigated whether PCA regulated nuclear pyruvate kinase isoform M2(PKM2)function to protect cardiomyocytes.In rats subjected to isoprenaline,PCA attenuated heart injury and protected cardiomyocytes from apoptosis.Through DARTS and CETSA assays,we identified that PCA bound and promoted PKM2 nuclear translocation in cardiomyocytes exposed to oxygen/glucose deprivation(OGD).In the nucleus,PCA increased the binding of PKM2 to β-Catenin via preserving PKM2 acetylation,and the complex,in cooperation with T-cell factor 4(TCF4),was required for transcriptional induction of genes encoding anti-apoptotic proteins,contributing to rescuing cardiomyocyte survival.In addition,PCA ameliorated mitochondrial dysfunction and prevented mitochondrial apoptosis dependent on PKM2.Consistently,PCA increased the binding of PKM2 to β-Catenin,improved heart contractive function,normalized heart structure and attenuated oxidative damage in mice subjected to artery ligation,but the protective effects were lost in Pkm2-deficient heart.Together,we showed that PCA regulated nuclear PKM2 function to rescue cardiomyocyte survival via β-Catenin/TCF4 signaling cascade,suggesting the potential of pharmacological intervention of PKM2 shuttle to protect the heart. | Xunxun Wu Lian Liu Qiuling Zheng Haiping Hao Hui Ye Ping Li Hua Yang | 2021 | Acta Pharmaceutica Sinica B2021，11，11： | 4 |

| 5 | Dihydrotanshinone I preconditions myocardium against ischemic injury via PKM2 glutathionylation sensitive to ROS显示文摘Ischemic preconditioning(IPC)is a potential intervention known to protect the heart against ischemia/reperfusion injury,but its role in the no-reflow phenomenon that follows reperfusion is unclear.Dihydrotanshinone I(DT)is a natural compound and this study illustrates its role in cardiac ischemic injury from the aspect of IPC.Pretreatment with DT induced modest ROS production and protected cardiomyocytes against oxygen and glucose deprivation(OGD),but the protection was prevented by a ROS scavenger.In addition,DT administration protected the heart against isoprenaline challenge.Mechanistically,PKM2 reacted to transient ROS via oxidization at Cys423/Cys424,leading to glutathionylation and nuclear translocation in dimer form.In the nucleus,PKM2 served as a co-factor to promote HIF-1a-dependent gene induction,contributing to adaptive responses.In mice subjected to permanent coronary ligation,cardiac-specific knockdown of Pkm2 blocked DT-mediated preconditioning protection,which was rescued by overexpression of wild-type Pkm2,rather than Cys423/424-mutated Pkm2.In conclusion,PKM2 is sensitive to oxidation,and subsequent glutathionylation promotes its nuclear translocation.Although IPC has been viewed as a protective means against reperfusion injury,our study reveals its potential role in protection of the heart from no-reflow ischemia. | Xunxun Wu Lian Liu Qiuling Zheng Hui Ye Hua Yang Haiping Hao Ping Li | 2023 | Acta Pharmaceutica Sinica B2023，13，1： | 1 |

| 7 | Microfluidic magnetic detection system combined with a DNA framework-mediated immune-sandwich assay for rapid and sensitive detection of tumor-derived exosomes显示文摘Tumor-derived circulating exosomes(TDEs)are being pursued as informative and noninvasive biomarkers.However,quantitatively detecting TDEs is still challenging.Herein,we constructed a DNA tetrahedral-structured probe(TSP)-mediated microfluidic magnetic detection system(μFMS)to provide a rapid and sensitive platform for analyzing TDEs.CD63 aptamer-modified Fe_(3)O_(4)magnetic nanoparticles(MNPs)were constructed to form magnetic nano-report probes(MNRs).The microfluidic chips were fabricated from glass functionalized with DNA TSP-modified aldehyde groups and a PDMS layer designed with serpentine microchannels.An induction coil-based magnetic detector was used to measure the magnetic signal.The linear dynamic range of theμFMS system for TDE assays was 1.98×10^(3)-1.98×10^(7)particles/mL with a limit of detection of 1.98×10^(3)particles/mL in PBS.There was no significant difference in TDE detection between the simulated serum and PBS,which indicated the feasibility of the constructedμFMS system for TDE analysis in complex biological systems.In terms of cost,reaction time and operation procedure,thisμFMS has the potential to be developed as a clinical point-of-care testing tool for cancer diagnosis and therapeutics. | Qiuling Qian Yutong Wei Yi Xu Mengmeng Zheng Chenguang Wang Shulin Zhang Xiaoming Xie Chaofeng Ye Xianqiang Mi | 2023 | Microsystems & Nanoengineering2023，9，6： | 0 |
| 8 | A New Edge Perturbation Mechanism for Privacy-Preserving Data Collection in IOT显示文摘A growing amount of data containing the sensitive information of users is being collected by emerging smart connected devices to the center server in Internet of things(IoT)era,which raises serious privacy concerns for millions of users.However,existing perturbation methods are not effective because of increased disclosure risk and reduced data utility,especially for small data sets.To overcome this issue,we propose a new edge perturbation mechanism based on the concept of global sensitivity to protect the sensitive information in IoT data collection.The edge server is used to mask users’sensitive data,which can not only avoid the data leakage caused by centralized perturbation,but also achieve better data utility than local perturbation.In addition,we present a global noise generation algorithm based on edge perturbation.Each edge server utilizes the global noise generated by the center server to perturb users’sensitive data.It can minimize the disclosure risk while ensuring that the results of commonly performed statistical analyses are identical and equal for both the raw and the perturbed data.Finally,theoretical and experimental evaluations indicate that the proposed mechanism is private and accurate for small data sets. | CHEN Qiuling YE Ayong ZHANG Qiang HUANG Chuan | 2023 | Chinese Journal of Electronics2023，32，3： | 0 |
