| 1 | Heat-sensitive moxibustion for lumbar disc herniation:a meta-analysis of randomized controlled trials显示文摘OBJECTIVE:To assess the efficacy and safety of heat-sensitive moxibustion in the treatment of lumbar disc herniation(LDH).METHODS:Randomized controlled trials(RCTs) involving heat-sensitive moxibustion in the treatment of LDH were retrieved from the Chinese Biological Medical Literature database(1978-20011),Weipu database(1989-2011),Wanfang digital journal(1998-2011),China National Knowledge Internet(1979-2011),PubMed(1966-2011),EMBASE(1980-2011),and Cochrane Library(Issue 1,2011).Hand-search of the relevant journals from the Library of Jiangxi University of Traditional Chinese Medicine was also adopted for the collection of data.Data were extracted and evaluated by two reviewers independently with a specially designed extraction form.The Cochrane Collaboration's RevMan 5.0.20 software was used for data analyses.RESULTS:A total of 6 trials involving 580 patients were included.Meta-analysis showed that the total effectiveness rate in the heat-sensitive moxibustion group was significantly different when compared with conventional moxibustion [RR=1.19,95% CI [1.06,1.33)] and diclofenac sodium [RR=1.47,95% CI [1.17,1.85)],but similar to that of acupuncture.The cure rate in the heat-sensitive moxibustion group was significantly different when compared with conventional moxibustion [RR=1.58,95% CI(1.04,2.40)] and diclofenac sodium [RR=1.91,95% CI(1.01,3.60)],but similar with that of acupuncture.In terms of the Japanese Orthopaedic Association scores,significant differences were noted in subjective indices,objective indices,and daily life subscales.Two trials reported that there were no adverse events over the duration of treatment.CONCLUSION:Compared with conventional moxibustion,acupuncture,and diclofenac sodium,heat-sensitive moxibustion in the treatment of LDH is superior in efficacy.Further large-scale trials are required to define the role of heat-sensitive moxibustion in the treatment of this disease. | Rixin Chen Jun Xiong Zhenhai Chi Bo Zhang | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 33 |
| 2 | Curative effect of heat-sensitive moxibustion on chronic persistent asthma: a multicenter randomized controlled trial显示文摘OBJECTIVE:To compare the curative effects of heat-sensitive moxibustion with conventional drugs on chronic persistent asthma and seek a valuable therapy to replaceWestern Medicine.METHODS:The participants in this multi-center,randomized,and controlled study were randomly divided into two groups:group A(n=144),treated with heat-sensitive moxibustion(50 sessions)and group B(n=144),treated with Seretide(salmeterol50μg/fluticasone 250μg,twice a day).The scores of asthma control test(ACT),forced expiratory volume in 1 second(FEV1),peak expiratory flow(PEF),and attack frequency were measured after 15,30,60,and 90 days of treatment.Patients followed up3 and 6 months after treatment.RESULTS:There was a significant difference(P=0.0002)in the ACT score and lung function between the two groups after 3 months of treatment and(P=0.000 03)during the follow-up visits.In addition,heat-sensitive moxibustion reduced attack frequency in the period from inclusion to the6-month follow-up visit.CONCLUSION:This study shows that heat-sensitive moxibustion may have a comparable curative effect toSeretide(salmeterol/fluticasone)on asthma. | Rixin Chen Mingren Chen Jun Xiong Zhenhai Chi B0 Zhang Ning Tian Zhenhua Xu Tangfa Zhang Wanyao Li Wei Zhang Xiaofeng Rong Zhen Wang Gang Sun Baohe Ge Guoxiong Yu Nanchang Song | 2013 | Journal of Traditional Chinese Medicine2013，33，5： | 20 |
| 3 | 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 |
| 4 | Potentiating CD8^(+) T cell antitumor activity by inhibiting PCSK9 to promote LDLR-mediated TCR recycling and signaling显示文摘Metabolic regulation has been proven to play a critical role in T cell antitumor immunity.However,cholesterol metabolism as a key component of this regulation remains largely unexplored.Herein,we found that the low-density lipoprotein receptor(LDLR),which has been previously identified as a transporter for cholesterol,plays a pivotal role in regulating CD8+T cell antitumor activity.Besides the involvement of cholesterol uptake which is mediated by LDLR in T cell priming and clonal expansion,we also found a non-canonical function of LDLR in CD8+T cells:LDLR interacts with the T-cell receptor(TCR)complex and regulates TCR recycling and signaling,thus facilitating the effector function of cytotoxic T-lymphocytes(CTLs).Furthermore,we found that the tumor microenvironment(TME)downregulates CD8+T cell LDLR level and TCR signaling via tumor cell-derived proprotein convertase subtilisin/kexin type 9(PCSK9)which binds to LDLR and prevents the recycling of LDLR and TCR to the plasma membrane thus inhibits the effector function of CTLs.Moreover,genetic deletion or pharmacological inhibition of PCSK9 in tumor cells can enhance the antitumor activity of CD8+T cells by alleviating the suppressive effect on CD8+T cells and consequently inhibit tumor progression.While previously established as a hypercholesterolemia target,this study highlights PCSK9/LDLR as a potential target for cancer immunotherapy as well. | Juanjuan Yuan Ting Cai Xiaojun Zheng Yangzi Ren Jingwen Qi Xiaofei Lu Huihui Chen Huizhen Lin Zijie Chen Mengnan Liu Shangwen He Qijun Chen Siyang Feng Yingjun Wu Zhenhai Zhang Yanqing Ding Wei Yang | 2021 | Protein & Cell2021，12，4： | 12 |
| 5 | Prognostic value of preoperative prognostic nutritional index and its associations with systemic inflammatory response markers in patients with stage Ⅲ colon cancer显示文摘Background: The prognostic nutritional index(PNI) has been widely applied for predicting survival outcomes of patients with various malignant tumors. Although a low PNI predicts poor prognosis in patients with colorectal cancer after tumor resection, the prognostic value remains unknown in patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy. This study aimed to investigate the prognostic value of PNI in patients with stage III colon cancer.Methods: Medical records of 274 consecutive patients with stage Ⅲ colon cancer undergoing curative tumor resection followed by adjuvant chemotherapy with oxaliplatin and capecitabine between December 2007 and December2013 were reviewed. The optimal PNI cutoff value was determined using receiver operating characteristic(ROC) curve analysis. The associations of PNI with systemic inflammatory response markers, including lymphocyte-to-monocyte ratio(LMR), neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), and C-reactive protein(CRP)level, and clinicopathologic characteristics were assessed using the Chi square or Fisher's exact test. Correlation analysis was performed using Spearman's correlation coefficient. Disease-free survival(DFS) and overall survival(OS)stratified by PNI were analyzed using Kaplan-Meier method and log-rank test, and prognostic factors were identified by Cox regression analyses.Results: The preoperative PNI was positively correlated with LMR(r= 0.483, P < 0.001) and negatively correlated with NLR(r =-0.441, P < 0.001), PLR(r =-0.607, P < 0.001), and CRP level(r =-0.333, P < 0.001). A low PNI(≤49.22)was significantly associated with short OS and DFS in patients with stage ⅢC colon cancer but not in patients with stage ⅢA/ⅢB colon cancer.In addition, patients with a low PNI achieved a longer OS and DFS after being treated with6-8 cycles of adjuvant chemotherapy than did those with < 6 cycles. Multivariate analyses revealed that PNI was independently associated with DFS(hazard ratios 2.001; 95% confidence interval 1.157-3.462; P = 0.013).Conclusion: The present study identified preoperative PNI as a valuable predictor for survival outcomes in patients with stage Ⅲ colon cancer receiving curative tumor resection followed by adjuvant chemotherapy. | Jianhong Peng Rongxin Zhang Yixin Zhao Xiaojun Wu Gong Chen Desen Wan Zhenhai Lu Zhizhong Pan | 2017 | Chinese Journal of Cancer2017，36，11： | 11 |
| 6 | Effectiveness and safety of heat-sensitive moxibustion on bronchial asthma:a Meta-analysis of randomized control trials显示文摘OBJECTIVE: To systematically evaluate the effectiveness and safety of heat-sensitive moxibustion(HSM)onasthma.METHODS: Large databases in China and overseas were searched by electronic and manual means to collect information on randomized controlled trials(RCTs).Two evaluators independently extracted data and evaluated the quality of RCTs according to Cochrane Review Handbook v5.0. RevMan v5.0.20 was used for statisticalanalyses.RESULTS: Fourteen RCTs involving 637 patients were collected.Thirteen RCTs compared the effects of HSM and Western Medicine. After 3-month treatment and after 6-month follow-up, there was no significant difference in effective rate [relative risk(RR)=1.01, 95% CI(0.92, 1.12), and 1.12,(0.93, 1.36),respectively], in the asthma control test score of asthma symptoms [weighted mean difference(WMD)=﹣1.54, 95% CI(﹣3.54, 0.47), and 1.41,(﹣0.48, 3.29), respectively] and in the forced expiratory volumein 1 second(FEV1)and peak expiratory flow(PEF). One RCT compared the effect of HSM with warm-suspended moxibustion. After 6-month follow-up, there was a significant difference in FEV1 and PEF [WMD=0.51, 95% CI(0.10, 0.92), and 1.78,(1.06, 2.50), respectively]. After 3-month treatment,there was no significant difference between the two groups. One RCT compared the effect of HSM with acupoint application. After 3-month treatment, there was no significant difference in the effectiverate[RR=0.68,95%CI(0.42,1.12)].CONCLUSION: HSM did not show superiority to conventional Western Medicine and acupoint application in terms of curative effects, and may be superior to warm-suspended moxibustion with regard to long-term curative effects. Because of low quality of the included RCTs, this conclusion must be bolstered with higher-quality RCTs. | Jun Xiong Zhongyong Liu Rixin Chen Dingyi Xie Zhenhai Chi Bo Zhang | 2014 | Journal of Traditional Chinese Medicine2014，34，4： | 11 |
| 7 | Ⅲ期结肠癌患者术前预后营养指数的预后价值及其与全身炎症反应标志物的相关性显示文摘背景与目的预后营养指数(prognostic nutritional index,PNI)已广泛应用于预测各种恶性肿瘤患者的生存结局。虽然低PNI预测肿瘤切除后的结直肠癌患者的预后不良,但对接受根治性肿瘤切除术后辅助化疗的Ⅲ期结肠癌患者的预后价值仍未知。本研究旨在探讨PNI对Ⅲ期结肠癌患者的预后价值。方法本文回顾了2007年12月至2013年12月期间,274例接受根治性肿瘤切除术后接受奥沙利铂和卡培他滨辅助化疗的Ⅲ期结肠癌的连续患者的医疗记录。采用受试者工作特征(receiver operating characteristic,ROC)曲线分析确定最佳PNI临界值。采用卡方检验或Fisher’s精确检验评估PNI与全身炎症反应标志物[包括淋巴细胞与单核细胞比值(lymphocyte-to-monocyte ratio,LMR)、中性粒细胞与淋巴细胞比值(neutrophil-to-lymphocyte ratio,NLR)、血小板与淋巴细胞比值(platelet-to-lymphocyte ratio,PLR)、C反应蛋白(C-reactive protein,CRP)水平]和临床病理特征的相关性。采用Spearman’s相关系数进行相关分析。采用Kaplan-Meier法和log-rank检验分析PNI分层的无病生存期(disease-free survival,DFS)和总生存期(overall survival,OS),并通过Cox回归分析确定预后因子。结果术前PNI与LMR呈正相关(r=0.483,P <0.001),与NLR(r=-0.441,P <0.001)、PLR(r=-0.607,P <0.001)和CRP水平(r=-0.333,P <0.001)呈负相关。在ⅢC期结肠癌患者中,低PNI(≤49.22)与短OS和DFS显著相关,而在ⅢA/ⅢB期结肠癌患者中则不相关。此外,在PNI低的患者中,接受6–8个疗程辅助化疗的患者比接受<6个疗程治疗的患者获得了更长的OS和DFS。多变量分析显示PNI与DFS独立相关(风险比=2.001;95%置信区间:1.157–3.462;P=0.013)。结论术前PNI是接受根治性肿瘤切除术后辅助化疗的Ⅲ期结肠癌患者生存结局的重要预测指标。 | Jianhong Peng Rongxin Zhang Yixin Zhao Xiaojun Wu Gong Chen Desen Wan Zhenhai Lu Zhizhong Pan | 2019 | 癌症2019，38，1： | 10 |
| 8 | Total mesorectal excision with or without preoperative chemoradiotherapy for resectable mid/low rectal cancer: a long-term analysis of a prospective, single-center, randomized trial显示文摘Background:The preliminary results of our phase II randomized trial reported comparable functional sphincter pres-ervation rates and short-term survival outcomes between patients undergoing total mesorectal excision(TME)with or without preoperative concurrent chemoradiotherapy(CCRT).We now report the long-term results after a median follow-up of 71 months.Methods:Between March 23,2008 and August 2,2012,192 patients with T3-T4 or node-positive,resectable,mid/low rectal adenocarcinoma were randomly assigned to receive TME with or without preoperative CCRT.The following endpoints were assessed:cumulative rates of local recurrence and distant metastasis,disease-free survival(DFS),and overall survival(OS).Results:The data of 184 eligible patients were analyzed:94 patients in the TME group and 90 patients in the CCRT+TME group.In the whole cohort,the 5-year DFS and OS rates were 84.8%and 85.1%,respectively.The 5-year DFS rates were 85.2%in the CCRT+TME group and 84.3%in the TME group(P=0.969),and the 5-year OS rates were 83.5%in the CCRT+TME group and 86.5%in the TME group(P=0.719).The 5-year cumulative rates of local recur-rence were 6.3%and 5.0%(P=0.681),and the 5-year cumulative rates of distant metastasis were 15.0%and 15.7%(P=0.881)in the CCRT+TME and TME groups,respectively.No significant improvements in 5-year DFS and OS were observed with CCRT by subgroup analyses.Conclusions:Both treatment strategies yielded similar long-term outcomes.A selective policy towards preoperative CCRT is thus recommended for rectal cancer patients if high-quality TME surgery and enhanced chemotherapy can be performed. | Fulong Wang Wenhua Fan Jianhong Peng Zhenhai Lu Zhizhong Pan Liren Li Yuanhong Gao Hui Li Gong Chen Xiaojun Wu Peirong Ding Zhifan Zeng Desen Wan | 2018 | Cancer Communications2018，38，1： | 6 |
| 9 | Research progress in electrospinning engineering for all-solid-state electrolytes of lithium metal batteries显示文摘Owing to safety issue and low energy density of liquid lithium-ion batteries(LIBs),all-solid-state lithium metal batteries(ASLMBs)with unique all-solid-state electrolytes(SEs)have attracted wide attentions.This arises mainly from the advantages of the SEs in the suppression of lithium dendrite growth,long cycle life,and broad working temperature range,showing huge potential applications in electronic devices,electric vehicles,smart grids,and biomedical devices.However,SEs suffer from low lithiumion conductivity and low mechanical integrity,slowing down the development of practical ASLMBs.Nanostructure engineering is of great efficiency in tuning the structure and composition of the SEs with improved lithium-ion conductivity and mechanical integrity.Among various available technologies for nanostructure engineering,electrospinning is a promising technique because of its simple operation,cost-effectiveness,and efficient integration with different components.In this review,we will first give a simple description of the electrospinning process.Then,the use of electrospinning technique in the synthesis of various SEs is summarized,for example,organic nanofibrous matrix,organic/inorganic nanofibrous matrix,and inorganic nanofibrous matrix combined with other components.The current development of the advanced architectures of SEs through electrospinning technology is also presented to provide references and ideas for designing high-performance ASLMBs.Finally,an outlook and further challenges in the preparation of advanced SEs for ASLMBs through electrospinning engineering are given. | Manxi Wang Yaling Wu Min Qiu Xuan Li Chuanping Li Ruiling Li Jiabo He Ganggang Lin Qingrong Qian Zhenhai Wen Xiaoyan Li Ziqiang Wang Qi Chen Qinghua Chen Jinhyuk Lee Yiu-Wing Mai Yuming Chen | 2021 | Journal of Energy Chemistry2021，30，10： | 4 |
| 10 | Determining the optimal time for bortezomib-based induction chemotherapy followed by autologous hematopoietic stem cell transplant in the treatment of multiple myeloma显示文摘In our study, we determined the efficacy of bortezomib-based induction therapy followed by autologous stem cell transplant (ASCT) in newly diagnosed and relapsed/refractory (R/R) multiple myeloma (MM) patients and compared the advantages of early versus late transplant. We used a retrospective analysis to examine 62 patients, including 46 cases of newly diagnosed MM (early transplant group) and 16 cases of relapsed/refractory MM (late transplant group). All of these patients received bortezomib-based induction therapy followed by ASCT. The efficacy and side effects of the treatment regimen were analyzed. Patients' overall survival (OS) and progression-free survival (PFS) times were determined. The ratio of complete remission to near-complete remission (CR/nCR) was 69.5% versus 56.2% (P=0.361), respectively, for the early transplant group versus the late transplant group, respectively, after receiving bortezomib-based induction therapy; the overall response rates of the two group were 91.3% and 81.2%, respectively (P=0.369). After receiving ASCT, the CR/nCR of the two groups increased to 84.8% and 81.3%, respectively. The median time required for neutrophil engraftment of the early transplant group and the late transplant group was 11 and 14.5 days, respectively (P=0.003); the median time required for platelet engraftment was 13 and 21.5 days (P=0.031), respectively. There were no significant differences in the toxic side effects observed during induction therapy and ASCT between the two groups. The OS of the two groups was not statistically different (P=0.058). The PFS of the early transplant group and the late transplant group was 41.6 and 26.5 months, respectively (P=0.008). Multivariate analysis demonstrated that the time of receiving ASCT, the types of M protein, and the International Staging System (ISS) stage were all independent factors that influenced PFS. In conclusion, patients in a suitable condition for ASCT should be recommended to have an early ASCT immediately after diagnosis. | Junru Liu Juan Li Beihui Huang Dong Zheng Mei Chen Zhenhai Zhou Duorong Xu Waiyi Zou | 2013 | Chinese Journal of Cancer Research2013，25，2： | 4 |
| 11 | Is there a survival benefit from adjuvant chemotherapy for patients with liver oligometastases from colorectal cancer after curative resection?显示文摘Background:Although colorectal oligometastases to the liver can potentially be cured with aggressive local abla-tion,the efficacy of adjuvant chemotherapy(ACT)for such metastasis remains unclear.The present study explored the effects of ACT on patients with colorectal liver oligometastases(CLO)after curative resections and aimed to iden-tify patients who could benefit from ACT.Methods:We retrospectively analyzed 264 eligible patients with CLO who underwent curative resection between September 1999 and June 2015.Recurrence-free survival(RFS)and overall survival(OS)were analyzed using the Kaplan-Meier method and log-rank test;prognostic factors were a by Cox regression modeling.Results:Among 264 patients,200(75.8%)patients received ACT and 64(24.2%)did not receive ACT.These two groups did not significantly differ in clinicopathologic characteristics,and had comparable 3-year OS and RFS rates(RFS:42.1%vs.45.7%,P=0.588;OS:69.7%vs.62.7%,P=0.446)over a median follow-up duration of 35.5 months,irrespective of preoperative chemotherapy.ACT markedly improved 3-year OS in high-risk patients with Memorial Sloan-Kettering Cancer Center clinical risk scores(MSKCC-CRS)of 3-5(68.2%vs.33.8%,P=0.015),but presented no additional benefit in patients with MSKCC-CRS of 0-2(72.2%vs.78.6%,P=0.834).In multivariate analysis,ACT was independently associated with improved OS in patients with MSKCC-CRS of 3-5.Conclusions:ACT might offer a prognostic benefit in high-risk patients with CLOs after curative liver resection,but not in low-risk patients.Therefore,patients’risk status should be determined before ACT administration to optimize postoperative therapeutic strategies. | Zhizhong Pan Jianhong Peng Junzhong Lin Gong Chen Xiaojun Wu Zhenhai Lu Yuxiang Deng Yujie Zhao Qiaoqi Sui Desen Wan | 2018 | Cancer Communications2018，38，1： | 4 |

| 14 | 对可切除的中/低位直肠癌是/否进行术前放化疗的全直肠系膜切除术研究:一项前瞻性、单中心、随机试验的长期分析显示文摘背景与目的我们的Ⅱ期随机试验的初步研究结果显示,对进行全直肠系膜切除术(total mesorectal excision,TME)的患者是/否进行术前同步放化疗(concurrent chemoradiotherapy,CCRT),二者的功能性括约肌保留率和短期生存结局相近。在经过中位71个月的随访后,现报告这一长期试验的结果。方法在2008年3月23日至2012年8月2日期间,192例患有T3–T4或淋巴结阳性、可切除的中/低直肠腺癌患者被随机分为接受或不接受术前CCRT组,之后均进行TME。评估以下终点:局部复发和远处转移的累积率、无病生存(disease?free survival,DFS)和总生存(overall survival,OS)。结果对入组的184例患者资料进行分析,其中TME组有94例,CCRT+TME组有90例。在整个队列中,5年DFS和OS率分别为84.8%和85.1%。CCRT+TME组的5年DFS率为85.2%,TME组为84.3%(P=0.969);CCRT+TME组的5年OS率为83.5%,TME组为86.5%(P=0.719)。在CCRT+TME和TME组中,局部复发的5年累积率分别为6.3%和5.0%(P=0.681),远处转移的5年累积率分别为15.0%和15.7%(P=0.881)。通过亚组分析,接受CCRT未观察到5年DFS和OS的显著改善。结论两种治疗方案的长期结局相近。因此,如果可以进行高质量的TME手术和强化化疗,建议选择性地对直肠癌患者进行术前CCRT。 | Fulong Wang Wenhua Fan Jianhong Peng Zhenhai Lu Zhizhong Pan Liren Li Yuanhong Gao Hui Li Gong Chen Xiaojun Wu Peirong Ding Zhifan Zeng Desen Wan | 2019 | 癌症2019，38，5： | 2 |
| 15 | Mechanical activation of spike fosters SARS-CoV-2 viral infection显示文摘The outbreak of SARS-CoV-2(SARS2)has caused a global COVID-19 pandemic.The spike protein of SARS2(SARS2-S)recognizes host receptors,including ACE2,to initiate viral entry in a complex biomechanical environment.Here,we reveal that tensile force,generated by bending of the host cell membrane,strengthens spike recognition of ACE2 and accelerates the detachment of spike’s S1 subunit from the S2 subunit to rapidly prime the viral fusion machinery.Mechanistically,such mechano-activation is fulfilled by force-induced opening and rotation of spike’s receptor-binding domain to prolong the bond lifetime of spike/ACE2 binding,up to 4 times longer than that of SARS-S binding with ACE2 under 10 pN force application,and subsequently by force-accelerated S1/S2 detachment which is up to~103 times faster than that in the no-force condition.Interestingly,the SARS2-S D614G mutant,a more infectious variant,shows 3-time stronger force-dependent ACE2 binding and 35-time faster force-induced S1/S2 detachment.We also reveal that an anti-S1/S2 non-RBD-blocking antibody that was derived from convalescent COVID-19 patients with potent neutralizing capability can reduce S1/S2 detachment by 3×106 times under force.Our study sheds light on the mechano-chemistry of spike activation and on developing a non-RBD-blocking but S1/S2-locking therapeutic strategy to prevent SARS2 invasion. | Wei Hu Yong Zhang Panyu Fei Tongtong Zhang Danmei Yao Yufei Gao Jia Liu Hui Chen Qiao Lu Tenny Mudianto Xinrui Zhang Chuxuan Xiao Yang Ye Qiming Sun Jing Zhang Qi Xie Pei-Hui Wang Jun Wang Zhenhai Li Jizhong Lou Wei Chen | 2021 | Cell Research2021，31，10： | 2 |
| 16 | Tailoring nanoprecipitates for ultra-strong high-entropy alloys via machine learning and prestrain aging显示文摘The multi-principal-component concept of high-entropy alloys(HEAs) generates numerous new alloys.Among them,nanoscale precipitated HEAs have achieved superior mechanical properties and shown the potentials for structural applications.However,it is still a great challe nge to find the optimal alloy within the numerous candidates.Up to now,the reported nanoprecipitated HEAs are mainly designed by a trialand-error approach with the aid of phase diagram calculations,limiting the development of structural HEAs.In the current work,a novel method is proposed to accelerate the development of ultra-strong nanoprecipitated HEAs.With the guidance of physical metallurgy,the volume fraction of the required nanoprecipitates is designed from a machine learning of big data with thermodynamic foundation while the morphology of precipitates is kinetically tailored by prestrain aging.As a proof-of-principle study,an HEA with superior strength and ductility has been designed and systematically investigated.The newly developed γ’-strengthened HEA exhibits 1.31 GPa yield strength,1.65 GPa ultimate tensile strength,and 15% tensile elongation.Atom probe tomography and transmission electron microscope characterizations reveal the well-controlled high γ’ volume fraction(52%) and refined precipitate size(19 nm).The refinement of nanoprecipitates originates from the accelerated nucleation of the γ’ phase by prestrain aging.A deeper understanding of the excellent mechanical properties is illustrated from the aspect of strengthening mecha nisms.Finally,the versatility of the current design strategy to other precipitation-hardened alloys is discussed. | Tao Zheng Xiaobing Hu Feng He Qjngfeng Wu Bin Han Chen Da Junjie Li Zhijun Wang Jincheng Wang Ji-jung Kai Zhenhai Xia C.T.Liu | 2021 | Journal of Materials Science & Technology2021，，10： | 2 |

| 18 | A 12-bit 250-MS/s Charge-Domain Pipelined Analog-to-Digital Converter with Feed-Forward Common-Mode Charge Control显示文摘A feed-forward Common-Mode(CM) charge control circuit for a high-speed Charge-Domain(CD)pipelined Analog-to-Digital Converter(ADC) is presented herein.This study aims at solving the problem whereby the precision of CD pipelined ADCs is restricted by the variation in input CM charge,which can compensate for CM charge errors caused by a variation in CM charge input in real time.Based on the feed-forward CM charge control circuit,a 12-bit 250-MS/s CD pipelined ADC is designed and realized using a 1 P6 M 0.18-μm CMOS process.The ADC achieved a Spurious Free Dynamic Range(SFDR) of 78.1 d B and a Signal-to-Noise-and-Distortion Ratio(SNDR) of 64.6 d B for a 20.1-MHz input:a SFDR of 74.9 d B and SNDR of 62.0 d B were achieved for a 239.9-MHz input at full sampling rate.The variation in signal-to-noise ratio was less than 3 d B over a 0–1.2 V input CM voltage range.The power consumption of the prototype ADC is only 85 m W at 1.8 V supply,and it occupies an active die area of 2.24 mm^2. | Zongguang Yu Xiaobo Su Zhenhai Chen Jiaxuan Zou Jinghe Wei Hong Zhang Yan Xue | 2018 | Tsinghua Science and Technology2018，23，1： | 2 |
| 19 | A large-scale outdoor atmospheric simulation smog chamber for studying atmospheric photochemical processes:Characterization and preliminary application显示文摘Understanding the formation mechanisms of secondary air pollution is very important for the formulation of air pollution control countermeasures in China.Thus,a large-scale outdoor atmospheric simulation smog chamber was constructed at Chinese Research Academy of Environmental Sciences(the CRAES Chamber),which was designed for simulating the atmospheric photochemical processes under the conditions close to the real atmospheric environment.The chamber consisted of a 56-m^(3) fluorinated ethylene propylene(FEP) Teflon film reactor,an electrically-driven stainless steel alloy shield,an auxiliary system,and multiple detection instrumentations.By performing a series of characterization experiments,we obtained basic parameters of the CRAES chamber,such as the mixing ability,the background reactivity,and the wall loss rates of gaseous compounds(propene,NO,NO_(2),ozone) and aerosols(ammonium sulfate).Oxidation experiments were also performed to study the formation of ozone and secondary organic aerosol(SOA),including α-pinene ozonolysis,propene and 1,3,5-trimethylbenzene photooxidation.Temperature and seed effects on the vapor wall loss and SOA yields were obtained in this work:higher temperature and the presence of seed could reduce the vapor wall loss;SOA yield was found to depend inversely on temperature,and the presence of seed could increase SOA yield.The seed was suggested to be used in the chamber to reduce the interaction between the gas phase and chamber walls.The results above showed that the CRAES chamber was reliable and could meet the demands for investigating tropospheric chemistry. | Junling Li Hong Li Xuezhong Wang Weigang Wang Maofa Ge Hao Zhang Xin Zhang Kun Li Yan Chen Zhenhai Wu Fahe Chai Fan Meng Yujing Mu Abdelwahid Mellouki Fang Bi Yujie Zhang Lingyan Wu Yongchun Liu | 2021 | Journal of Environmental Sciences2021，33，4： | 2 |
| 20 | A fast synthetic strategy for high-quality atomically thin antimonene with ultrahigh sonication power显示文摘Recent theoretical studies revealed that two-dimensional (2D) antimonene hasattractive characteristics, such as superior photothermal conductivity, absorptionover a wide range, high mobility, and good spintronic properties. Herein, we reporta reliable liquid phase exfoliation (LPE) route for the preparation of high-qualityhigh-stability atomically thin (AT) antimonene via high ultrasonic power. TheAT antimonene delivers a high specific capacity of up to 860 mA.h.g-1, with highrate capability and good cycling stability as an anode of a sodium ion battery(SIB). The good conductivity and 2D structure endow AT antimonene with moreactive sites for sodium storage, a facilitated pathway for electron transfer andmass transport, and the capability to reduce the volume expansion during thedischarge-charge process. | Wanzhen Lin Yaping Lian Guang Zeng Yanyan Chen Zhenhai Wen Huanghao Yang | 2018 | Nano Research2018，11，11： | 2 |
