| 1 | Hydrogen peroxide-induced changes in intracellular pH of guard cells precede stomatal closure显示文摘Epidermal bioassay demonstrated that benzylamine, a membrane-permeable weak base, can mimick hydrogen peroxide (H2O2) to induce stomatal closure, and butyric acid, a membrane-permeable weak acid, can partly abolish the H2O2-induced stomatal closure. Confocal pH mapping with the probe 5-(and-6)- carboxy seminaphthorhodafluor- 1 - acetoxymethylester (SNARF-1-AM) revealed that H2O2 leads to rapid changes in cytoplasmic and vacuolar pH in guard cells of Viola faba L, i. e. alkalinization of cytoplasmic areas occur red in parallel with a decrease of the vacuolar pH, and that butyric acid pretreatment can abolish alkalinization of cytoplasmic areas and acidification of vacuolar areas of guard cells challenged with H2O2. These results imply that the alkalinization of cytoplasm via efflux of cytosol protons into the vacuole in guard cells challenged with H2O2 is important at an early stage in the signal cascade leading to stomatal closure. | ZHANG XIAO, FA CAI DONG, JUN FENG GAO, CHUN PENG SONG (Department of Biology, Henan University, Kaifeng 475001, China) (College of Life Sciences, Northwest Sci-Tech University of Agriculture and Forestry, Yangling 712100, China) | 2001 | Cell Research2001,11,1: | 24 |

| 3 | Biodegradable chitosan scaffolds containing microspheres as carriers for controlled transforming growth factor-β_1 delivery for cartilage tissue engineering显示文摘Background Natural articular cartilage has a limited capacity for spontaneous regeneration.Controlled release oftransforming growth factor-β_1(TGF-β_1)to cartilage defects can enhance chondrogenesis.In this study,we assessed thefeasibility of using biodegradable chitosan microspheres as carriers for controlled TGF-β_1 delivery and the effect ofreleased TGF-β_1 on the chondrogenic potential of chondrocytes.Methods Chitosan scaffolds and chitosan microspheres loaded with TGF-β_1 were prepared by the freeze-drying andthe emulsion-crosslinking method respectively.In vitro drug release kinetics,as measured by enzyme-linkedimmunosorbent assay,was monitored for 7 days.Lysozyme degradation was performed for 4 weeks to detect in vitrodegradability of the scaffolds and the microspheres.Rabbit chondrocytes were seeded on the scaffolds containingTGF-β_1 microspheres and incubated in vitro for 3 weeks.Histological examination and type Ⅱcollagenimmunohistochemical staining was performed to evaluate the effects of released TGF-β_1 on cell adhesivity,proliferationand synthesis of the extracellular matrix.Results TGF-β_1 was encapsulated into chitosan microspheres and the encapsulation efficiency of TGF-β_1 was high(90.1%).During 4 weeks of incubation in lysozyme solution for in vitro degradation,the mass of both the scaffolds andthe microspheres decreased continuously and significant morphological changes was noticed.From the releaseexperiments,it was found that TGF-β_1 could be released from the microspheres in a multiphasic fashion including aninitial burst phase,a slow linear release phase and a plateau phase.The release amount of TGF-β_1 was 37.4%,50.7%,61.3%,and 63.5% for 1,3,5,and 7 days respectively.At 21 days after cultivation,type Ⅱ collagen immunohistochemicalstaining was performed.The mean percentage of positive cells for collagen type II in control group(32.7%±10.4%)wassignificantly lower than that in the controlled TGF-β_1 release group(92.4%±4.8%,P<0.05).Both the proliferation rateand production of collagen type Ⅱ in the transforming growth factor-β_1 microsphere incorporated scaffolds weresignificantly higher than those in the scaffolds without microspheres,indicating that the activity of TGF-β_1 was retainedduring microsphere fabrication and after growth factor release.Conclusion Chitosan microspheres can serve as delivery vehicles for controlled release of TGF-β_1,and the releasedgrowth factor can augment chondrocytes proliferation and synthesis of extracellular matrix.Chitosan scaffoldsincorporated with chitosan microspheres loaded with TGF-β_1 possess a promising potential to be applied for controlledcytokine delivery and cartilage tissue engineering. | CAI Dao-zhang ZENG Chun QUAN Da-ping BU Li-si WANG Kun LU Hua-ding LI Xiao-feng | 2007 | Chinese Medical Journal2007,,3: | 20 |
| 4 | Ultrasound enhanced heterogeneous activation of peroxydisulfate by bimetallic Fe-Co/GAC catalyst for the degradation of Acid Orange 7 in water显示文摘Bimetallic Fe-Co/GAC(granular activated carbon) was prepared and used as heterogeneous catalyst in the ultrasound enhanced heterogeneous activation of peroxydisulfate(PS, S2O2-8) process. The effect of initial pH, PS concentration, catalyst addition and stirring rate on the decolorization of Acid Orange 7(AO7) was investigated. The results showed that the decolorization efficiency increased with an increase in PS concentration from 0.3 to 0.5 g/L and an increase in catalyst amount from 0.5 to 0.8g/L. But further increase in PS concentration and catalyst addition would result in an unpronounced increase in decolorization efficiency. In the range of 300 to 900 r/min, stirring rate had little effect on AO7 decolorization. The catalyst stability was evaluated by measuring decolorization efficiency for four successive cycles. | Chun Cai Liguo Wang Hong Gao Liwei Hou Hui Zhang | 2014 | Journal of Environmental Sciences2014,26,6: | 16 |

| 6 | Research on power electronic transformer applied in AC/DC hybrid distribution networks显示文摘The AC/DC hybrid distribution network is one of the trends in distribution network development, which poses great challenges to the traditional distribution transformer. In this paper, a new topology suitable for AC/DC hybrid distribution network is put forward according to the demands of power grid, with advantages of accepting DG and DC loads, while clearing DC fault by blocking the clamping double sub-module(CDSM) of input stage. Then, this paper shows the typical structure of AC/DC distribution network that is hand in hand. Based on the new topology, this paper designs the control and modulation strategies of each stage, where the outer loop controller of input stage is emphasized for its twocontrol mode. At last, the rationality of new topology and the validity of control strategies are verified by the steady and dynamic state simulation. At the same time, the simulation results highlight the role of PET in energy regulation. | Yiqun Miao Jieying Song Haijun Liu Zhengang Lu Shufan Chen Chun Ding Tianzhi Cao Linhai Cai Yuzhong Gong | 2018 | Global Energy Interconnection2018,1,3: | 14 |
| 7 | Activation of mTORC1 in subchondral bone preosteoblasts promotes osteoarthritis by stimulating bone sclerosis and secretion of CXCL12显示文摘Increasing evidences show that aberrant subchondral bone remodeling plays an important role in the development of osteoarthritis(OA).However,how subchondral bone formation is activated and the mechanism by which increased subchondral bone turnover promotes cartilage degeneration during OA remains unclear.Here,we show that the mechanistic target of rapamycin complex 1(mTORC1)pathway is activated in subchondral bone preosteoblasts(Osterix+)from OA patients and mice.Constitutive activation of mTORC1 in preosteoblasts by deletion of the mTORC1 upstream inhibitor,tuberous sclerosis 1,induced aberrant subchondral bone formation,and sclerosis with little-to-no effects on articular cartilage integrity,but accelerated posttraumatic OA development in mice.In contrast,inhibition of mTORC1 in preosteoblasts by disruption of Raptor(mTORC1-specific component)reduced subchondral bone formation and cartilage degeneration,and attenuated post-traumatic OA in mice.Mechanistically,mTORC1 activation promoted preosteoblast expansion and Cxcl12 secretion,which induced subchondral bone remodeling and cartilage degeneration during OA.A Cxcl12-neutralizing antibody reduced cartilage degeneration and alleviated OA in mice.Altogether,these findings demonstrate that mTORC1 activation in subchondral preosteoblasts is not sufficient to induce OA,but can induce aberrant subchondral bone formation and secrete of Cxcl12 to accelerate disease progression following surgical destabilization of the joint.Pharmaceutical inhibition of the pathway presents a promising therapeutic approach for OA treatment. | Chuangxin Lin Liangliang Liu Chun Zeng Zhong-Kai Cui Yuhui Chen Pinling Lai Hong Wang Yan Shao Haiyan Zhang Rongkai Zhang Chang Zhao Hang Fang Daozhang Cai Xiaochun Bai | 2019 | Bone Research2019,7,1: | 12 |

| 10 | Overview of multiplex immunohistochemistry/immunofluorescence techniques in the era of cancer immunotherapy显示文摘Conventional immunohistochemistry(IHC)is a widely used diagnostic technique in tissue pathology.However,this technique is associated with a number of limitations,including high inter-observer variability and the capacity to label only one marker per tissue section.This review details various highly multiplexed techniques that have emerged to circumvent these constraints,allowing simultaneous detection of multiple markers on a single tissue section and the comprehensive study of cell composition,cellular functional and cell-cell interactions.Among these techniques,multiplex Immunohistochemistry/Immunofluorescence(mIHC/IF)has emerged to be particularly promising.mIHC/IF provides high-throughput multiplex staining and standardized quantitative analysis for highly reproducible,efficient and cost-effective tissue studies.This technique has immediate potential for translational research and clinical practice,particularly in the era of cancer immunotherapy. | Wei Chang Colin Tan Sanjna Nilesh Nerurkar Hai Yun Cai Harry Ho Man Ng Duoduo Wu Yu Ting Felicia Wee Jeffrey Chun Tatt Lim Joe Yeong Tony Kiat Hon Lim | 2020 | Cancer Communications2020,40,4: | 11 |

| 12 | Abnormal Audit Fees and Audit Opinion–Further Evidence from China's Capital Market显示文摘The existing literature on audit opinion shopping provides inconsistent evidence on whether such shopping has any association with abnormal audit fees. In this paper, we hypothesize that firms engage in audit opinion shopping and pay an abnormal audit fee only when their degree of accounting quality is low. To examine the issue, we group firms on the basis of their change in return on assets(ROA), and show that abnormal audit fees improve audit opinions only among firms that engage local auditors and have a low degree of ROA, but report a large increase in ROA, especially when the ROA change is the result of abnormal accruals. We find no association between abnormal audit fees and audit opinion improvement for other firms. | Zanchun Xie Chun Cai Jianming Ye | 2010 | China Journal of Accounting Research2010,,Z1: | 9 |

| 14 | Decreased Average Albumin-to-Globulin Ratio During Radiotherapy Worsens the Prognosis of Esophageal Squamous Cell Carcinoma:Implications for Nutritional Management显示文摘Objective Malnutrition and cachexia are common in esophageal squamous cell carcinoma(ESCC)patients undergoing radiotherapy.This study evaluated how malnutrition-and cachexia-related indicators,including the albumin-to-globulin ratio(AGR),and their changes during radiotherapy predict the treatment outcomes.Methods We reviewed a total of 172 ESCC patients receiving radiotherapy(as a primary cohort)and performed a Cox regression analysis on potential prognostic factors,including the AGR,as well as the TNM stage and concomitant chemotherapy.A subsequent receiver operating characteristics(ROC)curve and Kaplan Meier survival analysis was performed for ESCC patients stratified by the average AGR cut-off point.Results In addition to the well-documented factors(i.e.TNM stage and concomitant chemotherapy),the average AGR was a significant prognostic factor for ESCC patients receiving radiotherapy.By plotting the ROC curve of the average AGR with regard to the ESCC prognosis,we obtained cut-off points for the overall patients(cut-off point:1.5,AUC:0.636),for patients with stageⅡ/Ⅲdisease(cut-off point:1.5,AUC:0.611),and for patients with stageⅣdisease(cut-off point:1.84,AUC:0.900).The ESCC patients with higher average AGR had a significantly more favorable OS compared with those with a lower average AGR.Notably,ESCC patients who had an increasingΔAGR during radiotherapy had a considerably more favorable OS compared with those with a decreasingΔAGR.All of these findings were reproducible in the validation cohort.Conclusion A lower average AGR is indicative of a poorer prognosis for ESCC patients following radiotherapy.Improving the nutritional status and preventing or ameliorating cachexia might contribute to improving the prognosis of ESCC patients. | Fen Cai Xiu Lian Zhang Xiao Ling Wu Ting Ting Zhuang Lei Huang Yi Fei Tu Yuan Yuan Lu Min Xia Jiang Qing Ying Zhang Yan Lin Chang Chun Ma | 2021 | Journal of Nutritional Oncology2021,6,2: | 8 |

| 16 | Vehicle height and leveling control of electronically controlled air suspension using mixed logical dynamical approach显示文摘Vehicle height and leveling control of electronically controlled air suspension(ECAS) still poses theoretical challenges for researchers that have not been adequately addressed in prior research. This paper investigates the design and verification of a new controller to adjust the vehicle height and to regulate the roll and pitch angles of the vehicle body(leveling control) during the height adjustment procedures. A nonlinear mechanism model of the vehicle height adjustment system is formulated to describe the dynamic behaviors of the system. By using mixed logical dynamical(MLD) approach, a novel control strategy is proposed to adjust the vehicle height by controlling the on-off statuses of the solenoid valves directly. On this basis, a correction algorithm is also designed to regulate the durations of the on-off statuses of the solenoid valves based on pulse width modulated(PWM) technology, thus the effective leveling control of the vehicle body can be guaranteed. Finally, simulations and vehicle tests results are presented to demonstrate the effectiveness and applicability of the proposed control methodology. | SUN Xiao Qiang CAI Ying Feng YUAN Chao Chun WANG Shao Hua CHEN Long | 2016 | Science China(Technological Sciences)2016,59,12: | 6 |

| 18 | FABP4 secreted by M1-polarized macrophages promotes synovitis and angiogenesis to exacerbate rheumatoid arthritis显示文摘Increasing evidence shows that adipokines play a vital role in the development of rheumatoid arthritis(RA).Fatty acid-binding protein 4(FABP4),a novel adipokine that regulates inflammation and angiogenesis,has been extensively studied in a variety of organs and diseases.However,the effect of FABP4 on RA remains unclear.Here,we found that FABP4 expression was upregulated in synovial M1-polarized macrophages in RA.The increase in FABP4 promoted synovitis,angiogenesis,and cartilage degradation to exacerbate RA progression in vivo and in vitro,whereas BMS309403(a FABP4 inhibitor)and anagliptin(dipeptidyl peptidase 4 inhibitor)inhibited FABP4 expression in serum and synovial M1-polarized macrophages in mice to alleviate RA progression.Further studies showed that constitutive activation of mammalian target of rapamycin complex 1(mTORC1)by TSC1 deletion specifically in the myeloid lineage regulated FABP4 expression in macrophages to exacerbate RA progression in mice.In contrast,inhibition of mTORC1 by ras homolog enriched in brain(Rheb1)disruption specifically in the myeloid lineage reduced FABP4 expression in macrophages to attenuate RA development in mice.Our findings established an essential role of FABP4 that is secreted by M1-polarized macrophages in synovitis,angiogenesis,and cartilage degradation in RA.BMS309403 and anagliptin inhibited FABP4 expression in synovial M1-polarized macrophages to alleviate RA development.Hence,FABP4 may represent a potential target for RA therapy. | Dong Guo Chuangxin Lin Yuheng Lu Hong Guan Weizhong Qi Hongbo Zhang Yan Shao Chun Zeng Rongkai Zhang Haiyan Zhang Xiaochun Bai Daozhang Cai | 2022 | Bone Research2022,10,4: | 5 |

| 20 | The Changing Trends of HIV/AIDS in An Ethnic Minority Region of China: Modeling the Epidemic in Liangshan Prefecture, Sichuan Province显示文摘Objective This study was to investigate the HIV current situation in Liangshan prefecture, in order to predict prevalence and transmission trends. Methods Region-specific population, behavior, serosurveillence, and policy/program data (from 1995 to 2010) were gathered from various local and national organizations and applied to the Asian Epidemic Model (AEM) and used to derive estimates of future HIV prevalence, epidemic trends, and outcomes of intervention strategies. Results The AEM projections for 2020 included increased number of people living with HIV (PLHIV; to 136 617), increased HIV prevalence (2.51%), and 8037 deaths from acquired immunodeficiency syndrome (AIDS) in this region. However, the overall HIV incidence rate (per 10 000) was projected to decline from 27 in 2015 to 22 in 2020, largely due to a predicted decrease in HIV infection rate (per 10 000) from 658 in 2013 to 621 in 2020 among intravenous drug users. In contrast, the cases of HIV infection per 10 000 was projected to increase from 420 in 2010 to 503 in 2020 among men who have sex with men, and from 8 in 2010 to 15 in 2020 among the general population. The predominant risk factor for HIV transmission over the next decade in Liangshan was casual sex. Community-based outreach strategies to reduce injected drug use and casual sex, and to promote condom use, were predicted as effective interventions to decrease HIV transmission. Conclusion Implementation of a comprehensive public health program, with targeting to the region-specific at-risk populations, will help tomitigate HIV/AIDS spread in Liangshan. | LIU Shou WANG Qi Xing NAN Lei WU Chun Lin WANG Zhao Fen BAI Zhen Zhong LIU Li CAI Peng QIN Si LUAN Rong Sheng | 2013 | Biomedical and Environmental Sciences2013,26,7: | 5 |
