2Networked Control Systems:A Survey of Trends and Techniques显示文摘Networked control systems are spatially distributed systems in which the communication between sensors, actuators,and controllers occurs through a shared band-limited digital communication network. Several advantages of the network architectures include reduced system wiring, plug and play devices,increased system agility, and ease of system diagnosis and maintenance. Consequently, networked control is the current trend for industrial automation and has ever-increasing applications in a wide range of areas, such as smart grids, manufacturing systems,process control, automobiles, automated highway systems, and unmanned aerial vehicles. The modelling, analysis, and control of networked control systems have received considerable attention in the last two decades. The ‘control over networks’ is one of the key research directions for networked control systems. This paper aims at presenting a survey of trends and techniques in networked control systems from the perspective of ‘control over networks’, providing a snapshot of five control issues: sampled-data control, quantization control, networked control, event-triggered control, and security control. Some challenging issues are suggested to direct the future research.Xian-Ming Zhang Qing-Long Han Xiaohua Ge Derui Ding Lei Ding Dong Yue Chen Peng 2020IEEE/CAA Journal of Automatica Sinica2020,7,1:25
3Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas.Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu 2019National Science Review2019,6,3:24
4Relationship between hs-CRP, proMMP-1, TIMP-1 and coronary plaque morphology: intravascular ultrasound study显示文摘Background Rupture of unstable plaque with subsequent thrombus formation is the common pathophy- siological substrate of the acute coronary syndrome (ACS). It is of potential significance to explore the blood indexes predicting plaque characteristics. Little studies have focused on this field. Therefore we investigated the relationship between hypersensitive C-reactive protein (hs-CRP), pro-matrix metalloproteinase-1 (proMMP-1), tissue inhibitors of matrix metalloproteinase-1 (TIMP-1) and coronary plaque morphology. Methods Intravascular ultrasound (IVUS) examination was done in 152 patients with confirmed coronary heart disease before percutaneous coronary intervention from February 2003 to July 2005. Plasma samples of arterial blood were collected prior to the procedure. The level of hs-CRP, proMMP-1 and TIMP-1 were respectively measured by enzyme-linked immunosorbent assay (ELISA). Results Unstable and ruptured plaque were found more frequently in patients with acute myocardial infarction and unstable angina. External elastic membrane cross-sectional area (EEM CSA), plaque area, lipid pool area and plaque burden were significantly larger in ruptured and unstable plaque group. Positive remolding, thinner fabric-cap, smaller minimal lumen cross-sectional area (MLA), dissection and thrombus were significantly more frequent in ruptured and unstable plaque group. The levels of plasma hs-CRP, proMMP-1 and TIMP-1 were higher in ruptured plaque group. hs-CRP>8.94 mg/L was used to predict ruptured plaque with a ROC curve area of 0.76 [95% confidence interval (CI), 67.0%-85.8%], sensitivity of 71.8%, specificity of 77.0% and accuracy of 69.2% (P<0.01), similarly for proMMP-1>0.12 ng/ml with a ROC curve area of 0.69 [95% CI, 58.2%-80.2%], sensitivity of 69.2%, specificity of 75.2% and accuracy of 66.2% (P<0.01), and TIMP-1>83.45 ng/ml with a ROC curve area of 0.67 [95% CI, 56.2%-78.3%], sensitivity of 66.7%, specificity of 61.9% and accuracy of 66.2% (P<0.01). Conclusion The plaque characteristics correlate with the clinical presentation. The elevation of hs-CRP, proMMP-1 and TIMP-1 are related to the plaque instability and rupture.ZHANG Xing-wei GE Jun-bo YANG Jian-min GE Lei WANG Ning-fu GAO Yan LI Pei-zhang PAN Hao TONG Guo-xin ZHOU Liang YE Xian-hua XU Jian 2006Chinese Medical Journal2006,,20:23

6Flow-induced vibrations of long circular cylinders modeled by coupled nonlinear oscillators显示文摘The dynamics of long slender cylinders undergoing vortex-induced vibrations (VIV) is studied in this work. Long slender cylinders such as risers or tension legs are widely used in the field of ocean engineering. When the sea current flows past a cylinder, it will be excited due to vortex shedding. A three-dimensional time domain model is formulated to describe the response of the cylinder, in which the in-line (IL) and cross-flow (CF) deflections are coupled. The wake dynamics, including in-line and cross-flow vibrations, is represented using a pair of non-linear oscillators distributed along the cylinder. The wake oscillators are coupled to the dynamics of the long cylinder with the acceleration coupling term. A non-linear fluid force model is accounted for to reflect the relative motion of cylinder to current. The model is validated against the published data from a tank experiment with the free span riser. The comparisons show that some aspects due to VIV of long flexible cylinders can be reproduced by the proposed model, such as vibrating frequency, dominant mode number, occurrence and transition of the standing or traveling waves. In the case study, the simulations show that the IL curvature is not smaller than CF curvature, which indicates that both IL and CF vibrations are important for the structural fatigue damage.GE Fei LONG Xu WANG Lei HONG YouShi 2009Science China(Physics,Mechanics & Astronomy)2009,52,7:20
7Effectiveness of 5-flurouracil-based neoadjuvant chemotherapy in locally-advanced gastric/gastroesophageal cancer:A meta-analysis显示文摘AIM:To investigate the effectiveness of 5-flurouracilbased neoadjuvant chemotherapy(NAC) for gastroesophageal and gastric cancer by meta-analysis.METHODS:MEDLINE and manual searches were performed to identify all published randomized controlled trials(RCTs) investigating the efficacy of the flurouracilbased NAC for gastroesophageal and gastric cancer,and RCTs of NAC for advanced gastroesophageal and gastric cancer vs no therapy before surgery.Studies that included patients with metastases at enrollment were excluded.Primary endpoint was the odds ratio(OR) for improving overall survival rate of patients with gastroesophageal and gastric cancer.Secondary endpoints were the OR of efficiency for down-staging tumor and increasing R0 resection in patients with gas-troesophageal and gastric cancer.Safety analyses were also performed.The OR was the principal measurement of effect,which was calculated as the treatment group(NAC plus surgery) vs control group(surgery alone) and was presented as a point estimate with 95% confidence intervals(CI).All calculations and statistical tests were performed using RevMan 5.1 software.RESULTS:Seven RCTs were included for the analysis.A total of 1249 patients with advanced gastroesophageal and gastric cancer enrolled in the seven trials were divided into treatment group(n = 620) and control group(n = 629).The quality scores of the RCTs were assessed according to the method of Jadad.The RCT quality scores ranged from 2 to 7(5-point scale),with a mean of 3.75.The median follow-up time in these studies was over 3 years.The meta-analysis showed that NAC improved the overall survival rate(OR 1.40,95%CI 1.11-1.76;P = 0.005),which was statistically significant.The 3-year progression-free survival rate was significantly higher in treatment group than in control group(37.7% vs 27.3%)(OR 1.62,95%CI 1.21-2.15;P = 0.001).The tumor down-stage rate was higher in treatment group than in control group(55.76% vs 41.38%)(OR 1.77,95%CI 1.27-2.49;P = 0.0009) and the R0 resection rate of the gastroesophageal and gastric cancer was higher in treatment group than in control group(75.11% vs 68.56%)(OR 1.38,95%CI 1.03-1.85;P = 0.03),with significant differences.No obvious safety concerns about mortality and complications were raised in these trials.There were no statistically significant differences in perioperative mortality(5.08% vs 4.86%)(OR 1.05,95%CI 0.57-1.94;P = 0.87 fixed-effect model) and in the complication rate between the two groups(13.25% vs 9.66%)(OR 1.40,95%CI 0.91-2.14;P = 0.12 fixed-effect model).Trials showed that patients from Western countries favored NAC compared with those from Asian countries(OR 1.40,95%CI 1.07-1.83).Monotherapy was inferior tomultiple chemotherapy(OR 1.40,95%CI 1.07-1.83).Intravenous administration of NAC was more advantageous than oral route(OR 1.41,95%CI 1.09-1.81).CONCLUSION:Flurouracil-based NAC can safely improve overall survival rate of patients with gastroesophageal/gastric cancer.Additionally,NAC can down the tumor stage and improve R0 resection.Lei Ge Hai-Jiang Wang Dong Yin Cheng Lei Jin-Feng Zhu Xiao-Hui Cai Guo-Qing Zhang 2012World Journal of Gastroenterology2012,18,48:19

9Effects of Xinfeng capsule on pulmonary function based on treg-mediated notch pathway in a rat model of adjuvant arthritis显示文摘OBJECTIVE:To observe the impact of xinfeng xapsule(XFC) on pulmonary function in a rat model of adjuvant arthritis(AA) and to investigate the mechanism of action.METHODS:Forty rats were randomly divided into four groups of ten:normal control(NC);model control(MC);tripterygium glycosides tablet(TPT);and xinfeng capsule(XFC).Except for the NC group,AA was induced in all rats by intracutaneous injection of 0.1 mL Freund's complete adjuvant in the right paw on the 19th day.NC and MC groups were given(0.9%) physiological saline.The TPT and XFC groups were given TPT(10 mg/kg) and XFC(1.2 g/kg),respectively.Thirty days after administration,changes in paw edema(E),the arthritis index(AI),pulmonary function,levels of regulatory T-cells(Treg),ultrastructure of lung tissue,and expression of Notch receptors and ligands in lung tissue were observed.RESULTS:In the MC group,E and the AI were increased and pulmonary function significantly decreased;the structure of alveolar type-II cells was damaged;ratios of Treg in peripheral blood were reduced;and expression of Notch receptors such as Notch3 and Notch4 and ligands such as Delta1 in lung tissue were significantly increased whereas expression of Notch1,Jagged1 and Jagged2 were significantly decreased.After intervention with XFC,E and the AI were decreased;pulmonary function was enhanced;the structure of alveolar type-II cells was improved;and expression of Treg,Notch1,Jagged1,Jagged2 was elevated,whereas that of Notch3,Notch4 and Delta1 was reduced.CONCLUSION:XFC can not only inhibit E and the AI and improve joint symptoms,it can also improve pulmonary function and reduce inflammation in lung tissue.These actions could be carried out through increases in the expression of Treg,Notch receptors(Notch1) and ligands(Jagged1,Jagged2),and reductions in the expression of Notch3,Notch4 and Delta1.These phenomena would reduce the deposition of immune complexes and the inflammatory response in lung tissue,thereby improving joint symptoms and pulmonary function.Lei Wan Jian Liu Chuanbing Huang Yuan Wang Xi Shen Wandong Zhang Guizheng Wang Haixia Fan Yao Ge Ruilian Chen Yunxiang Cao Ruikai Zong Li Lei 2012Journal of Traditional Chinese Medicine2012,32,3:17

11Ubiquitination of Rheb governs growth factor-induced mTORC1 activation显示文摘Mechanistic target of rapamycin mTOR complex 1 (mTORC1)plays a key role in the integration of various environmental signals to regulate cell growth and metabolism,mTORC1 is recruited to the lysosome where it is activated by its interaction with GTP-bound Rheb GTPase.However,the regulatory mechanism of Rheb activity remains largely unknown.Here,we show that ubiquitination governs the nucleotide-bound status of Rheb.Lysosome-anchored E3 ligase RNF152 catalyzes Rheb ubiquitination and promotes its binding to the TSC complex.EGF enhances the deubiquitination of Rheb through AKT-dependent USP4 phosphorylation,leading to the release of Rheb from the TSC complex.Functionally,ubiquitination of Rheb is linked to mTORC1-mediated signaling and consequently regulates tumor growth.Thus,we propose a mechanistic model whereby Rheb-mediated mTORC1 activation is dictated by a dynamic opposing act between Rheb ubiquitination and deubiquitination that are catalyzed by RNF152 and USP4 respectively.Lu Deng Lei Chen Linlin Zhao Yan Xu Xiaoping Peng Xinbo Wang Lin Ding Jiali Jin Hongqi Teng Yanming Wang Weijuan Pan Fei Yu Lujian Liao Li Li Xin Ge Ping Wang 2019Cell Research2019,29,2:16
12Effects of continuously regenerating diesel particulate filters on regulated emissions and number-size distribution of particles emitted from a diesel engine显示文摘The effects of continuously regenerating diesel particulate filter (CRDPF) systems on regulated gaseous emissions, and number-size distribution and mass of particles emanated from a diesel engine have been investigated in this study. Two CRDPF units (CRDPF-1 and CRDPF-2) with different specifications were separately retrofitted to the engine running with European steady-state cycle (ESC). An electrical low pressure impactor (ELPI) was used for particle number-size distribution measurement and mass estimation. The conversion/reduction rate (R CR ) of hydrocarbons (HC) and carbon monoxide (CO) across CRDPF-1 was 83% and 96.3%, respectively. Similarly, the R CR of HC and CO and across CRDPF-2 was 91.8% and 99.1%, respectively. The number concentration of particles and their concentration peaks; nuclei mode, accumulation mode and total particles; and particle mass were highly reduced with the CRDPF units. The nuclei mode particles at downstream of CRDPF-1 and CRDPF-2 decreased by 99.9% to 100% and 97.8% to 99.8% respectively; and the particle mass reduced by 73% to 92.2% and 35.3% to 72.4%, respectively, depending on the engine conditions. In addition, nuclei mode particles increased with the increasing of engine speed due to the heterogeneous nucleation initiated by the higher exhaust temperature, while accumulation mode particles were higher at higher loads due to the decrease in the air-to-fuel ratio (A/F) at higher loads.Zhihua Liu Asad Naeem Shah Yunshan Ge Yan Ding, Jianwei Tan Lei Jiang Linxiao Yu Wei Zhao Chu Wang Tao Zeng 2011Journal of Environmental Sciences2011,23,5:15
13The Predictive Value of Baseline HBs Ag Level and Early Response for HBs Ag Loss in Patients with HBe Ag-positive Chronic Hepatitis B during Pegylated Interferon Alpha-2a Treatment显示文摘Objective To explore the predictive value of baseline HBsAg level and early response for HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment. Methods A total of 121 patients with HBeAg-positive chronic hepatitis B who achieved HBsAg loss were enrolled; all patients were treated with PEG-IFNα-2a 180 μg/week. Serum HBV DNA and serological indicators(HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during treatment. Results The median treatment time for HBsAg loss was 84 weeks(7-273 weeks), and 74.38%(90 cases) of the patients needed extended treatment(> 48 weeks). The correlation between baseline HBsAg levels and the treatment time of HBsAg loss was significant(B = 14.465, t = 2.342, P = 0.021). Baseline HBsAg levels together with the decline range of HBsAg at 24 weeks significantly correlated with the treatment time of HBsAg loss(B = 29.862, t = 4.890, P = 0.000 and B = 27.993, t = 27.993, P = 0.005). Conclusion Baseline HBsAg levels and extended therapy are critical steps toward HBsAg loss. Baseline HBsAg levels together with early response determined the treatment time of HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment.LI Ming Hui ZHANG Lu QU Xiao Jing LU Yao SHEN Ge LI Zhen Zhen WU Shu Ling LIU Ru Yu CHANG Min HU Lei Ping HUA Wen Hao SONG Shu Jing WAN Gang XIE Yao 2017Biomedical and Environmental Sciences2017,30,3:14
14Microwave-assisted extraction of Shenfu coal and its macromolecule structure显示文摘Coals consist of some molecules trapped within an organic matrix from which some organic compounds can be extracted by solvents. The Soxhlet technique has been widely used for extracting organic compounds. Microwave heating methods may be successfully applied in the field of coal science. Acetone extraction yields and the chemical composition of the extract were investigated using a typical Chinese coal, Shenfu coal, with microwave-assisted extraction. The acetone extract and residue were analyzed by GC/MS and carbon-13 nuclear magnetic resonance spectroscopy respectively. The carbon spectra were converted into several numerical parameters, fa, Ha, Xb, which indicate the difference in macromolecular structure between Shenfu coal and its residue. Furthermore, a hybrid genetic algorithm was employed using these parameters to approximate a coal macromolecule by assembling the structural fragments or functional groups into a large and complicated structure.CHEN Hong LI Jian,wei LEI Zhao GE Ling-mei 2009Mining Science and Technology2009,19,1:13
15Impact of Traffic Emissions on Local Air Quality and the Potential Toxicity of Traffic-related Particulates in Beijing, China显示文摘Objective Air-borne particulates from different sources could have different physicochemical properties and inflammatory potentials. This study aims to characterize the chemical compositions and the toxicity of ambient particulate matter (PM) associated with traffic emissions. Methods The concentrations of trace elements, organic carbon (OC), elemental carbon (EC) and polycyclic aromatic hydrocarbons (PAHs) in PM 2.5 and PM 10 were measured in samples collected at sites in Beijing, China. Their toxic effects on the pulmonary system of rats were investigated. Biochemical parameters (LDH, T-AOC, TP) and inflammatory cytokine(IL-6, IL-1, TNF-α) levels were measured in the lungs of rats exposed to traffic-related PM. Oxidative damage was observed. PM samples were taken from a near road site and an off road site in summer time in 2006. Results The concentrations of the USEPA priority pollutant PAHs in both PM 10 and PM 2.5 were higher (299.658 and 348.412) at the near road site than those (237.728 and 268.472) at the off road site. The similar trend was observed for the concentrations of trace elements in PM. Compared to coarse particles (PM 10 ), fine particles (PM 2.5 ) have a greater adsorption capacity to enrich toxic elements than inhalable particles. Decrease in antioxidant capacity and an increase in the amount of lipid peroxidation products in rat lung tissues was observed. Conclusion The findings of the present study suggest that the differing inflammatory responses of PM collected from the two road sites might have been mediated by the differing physicochemical characteristics.TIAN Lei ZHANG Wei LIN Zhi Qing ZHANG Hua Shan XI Zhu Ge CHEN Jian Hua WANG Wei 2012Biomedical and Environmental Sciences2012,25,6:13

17Toripalimab combined with lenvatinib and GEMOX is a promising regimen as first-line treatment for advanced intrahepatic cholangiocarcinoma:a single-center,single-arm,phase 2 study显示文摘Advanced intrahepatic cholangiocarcinoma(ICC)has a dismal prognosis.Here,we report the efficacy and safety of combining toripalimab,lenvatinib,and gemcitabine plus oxaliplatin(GEMOX)as first-line therapy for advanced ICC.Thirty patients with pathologically confirmed advanced ICC received intravenous gemcitabine(1 g/m2)on Days 1 and 8 and oxaliplatin(85 mg/m2)Q3W for six cycles along with intravenous toripalimab(240 mg)Q3W and oral lenvatinib(8 mg)once daily for one year.The expression of programmed death-ligand 1(PD-L1)and genetic status was investigated in paraffin-embedded tissues using immunohistochemistry and whole-exome sequencing(WES)analysis.The primary endpoint was the objective response rate(ORR).Secondary outcomes included safety,overall survival(OS),progression-free survival(PFS),disease control rate(DCR)and duration of response(DoR).As of July 1,2022,the median follow-up time was 23.5 months,and the ORR was 80%.Twenty-three patients achieved partial response,and one achieved complete response.Patients(21/30)with DNA damage response(DDR)-related gene mutations showed a higher ORR,while patients(14/30)with tumor area positivity≥1(PD-L1 staining)showed a trend of high ORR,but without significant difference.The median OS,PFS,and DoR were 22.5,10.2,and 11.0 months,respectively.The DCR was 93.3%.Further,56.7%of patients experienced manageable grade≥3 adverse events(AEs),commonly neutropenia(40.0%)and leukocytopenia(23.3%).In conclusion,toripalimab plus lenvatinib and GEMOX are promising first-line regimens for the treatment of advanced ICC.A phase-III,multicenter,double-blinded,randomized study to validate our findings was approved by the National Medical Products Administration(NMPA,No.2021LP01825).Guo-Ming Shi Xiao-Yong Huang Dong Wu Hui-Chuan Sun Fei Liang Yuan Ji Yi Chen Guo-Huan Yang Jia-Cheng Lu Xian-Long Meng Xin-Ying Wang Lei Sun Ning-Ling Ge Xiao-Wu Huang Shuang-Jian Qiu Xin-Rong Yang Qiang Gao Yi-Feng He Yang Xu Jian Sun Zheng-Gang Ren Jia Fan Jian Zhou 2023Signal Transduction and Targeted Therapy2023,8,4:12
18Effect of high-strength ammonia nitrogen acclimation on sludge activity in sequencing batch reactor显示文摘The effect of high-strength ammonia nitrogen acclimation on sludge activity in sequencing batch reactor (SBR) was investigated. Two batch experiments, RUN1 and RUN2, were conducted with the influent ammonia nitrogen concentrations 60 and 500 mg/L, respectively. The sludges inoculated from RUN1 and RUN2 were used to treat a series of influent with ammonia nitrogen concentrations of 59, 232, 368, 604 and 1152 mg/L. It is found that the activated sludge acclimated to higher ammonia nitrogen concentrations revealed higher COD and NH 4 + -N removal efficiencies, and slower DHA decrease. The results confirmed that the activities of the bacteria in activated sludge in SBR were inhibited by high-strength ammonia nitrogen, whereas the activated sludge acclimated to high-strength ammonia nitrogen showed substantial resistance to inhibition by influents containing high levels of ammonia nitrogen.Feifei Wang, Yuanhong Ding, Lei Ge, Hongqiang Ren, Lili Ding State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing 210093, China. 2010Journal of Environmental Sciences2010,22,11:12
19Bioactive biodegradable polycitrate nanoclusters enhances the myoblast differentiation and in vivo skeletal muscle regeneration via p38 MAPK signaling pathway显示文摘Complete skeletal muscle repair and regeneration due to severe large injury or disease is still a challenge.Biochemical cues are critical to control myoblast cell function and can be utilized to develop smart biomaterials for skeletal muscle engineering.Citric acid-based biodegradable polymers have received much attention on tissue engineering,however,their regulation on myoblast cell differentiation and mechanism was few investigated.Here,we find that citrate-based polycitrate-polyethylene glycol-polyethylenimine(POCG-PEI600)nanoclusters can significantly enhance the in vitro myoblast proliferation by probably reinforcing the mitochondrial number,promote the myotube formation and full-thickness skeletal muscle regeneration in vivo by activating the myogenic biomarker genes expression of Myod and Mhc.POCG-PEI600 nanoclusters could also promote the phosphorylation of p38 in MAP kinases(MAPK)signaling pathway,which led to the promotion of the myoblast differentiation.The in vivo skeletal muscle loss rat model also confirmed that POCG-PEI600 nanoclusters could significantly improve the angiogenesis,myofibers formation and complete skeletal muscle regeneration.POCG-PEI600 nanocluster could be also biodegraded into small molecules and eliminated in vivo,suggesting their high biocompatibility and biosafety.This study could provide a bioactive biomaterial-based strategy to repair and regenerate skeletal muscle tissue.Yi Guo Min Wang Juan Ge Wen Niu Mi Chen Wei Cheng Bo Lei 2020Bioactive Materials2020,5,3:12
20Hydrogen sulfide suppresses transforming growth factor-β1-induced differentiation of human cardiac fibroblasts into myofibroblasts显示文摘In heart disease, transforming growth factor-β1(TGF-β1) converts fibroblasts into myofibroblasts, which synthesize and secrete fibrillar type I and III collagens. The purpose of the present study was to investigate how hydrogen sulfide(H2S) suppresses TGF-β1-induced differentiation of human cardiac fibroblasts to myofibroblasts. Human cardiac fibroblasts were serum-starved in fibroblast medium for 16 h before exposure to TGF-β1(10 ng m L-1) for 24 h with or without sodium hydrosulfide(Na HS, 100 μmol L-1, 30 min pretreatment) treatment. Na HS, an exogenous H2 S donor, potently inhibited the proliferation and migration of TGF-β1-induced human cardiac fibroblasts and regulated their cell cycle progression. Furthermore, Na HS treatment led to suppression of fibroblast differentiation into myofibroblasts, and reduced the levels of collagen, TGF-β1, and activated Smad3 in TGF-β1-induced human cardiac fibroblasts in vitro. We therefore conclude that H2 S suppresses TGF-β1-stimulated conversion of fibroblasts to myofibroblasts by inhibiting the TGF-β1/Smad3 signaling pathway, as well as by inhibiting the proliferation, migration, and cell cycle progression of human cardiac myofibroblasts. These effects of H2 S may play significant roles in cardiac remodeling associated with heart failure.ZHANG YouEn WANG JiaNing LI Hua YUAN LiangJun WANG Lei WU Bing GE JunBo 2015Science China(Life Sciences)2015,58,11:11
