1Diagnostic value of FIB-4, aspartate aminotransferaseto-platelet ratio index and liver stiffness measurement in hepatitis B virus-infected patients with persistently normal alanine aminotransferase显示文摘AIM To assess the diagnostic value of FIB-4, aspartate aminotransferase-to-platelet ratio index(APRI), and liver stiffness measurement(LSM) in patients with hepatitis B virus infection who have persistently normal alanine transaminase(PNALT).METHODS We enrolled 245 patients with chronic hepatitis B: 95 in PNALT group, 86 in intermittently elevated alanine transaminase(PIALT1) group [alanine transaminase(ALT) within 1-2 × upper limit of normal value(ULN)], and 64 in PIALT2 group(ALT > 2 × ULN). All the patients received a percutaneous liver biopsy guided by ultrasonography. LSM, biochemical tests, and complete blood cell counts were performed.RESULTS The pathological examination revealed moderate inflammatory necrosis ratios of 16.81%(16/95), 32.56%(28/86), and 45.31%(28/64), and moderate liverfibrosis of 24.2%(23/95), 33.72%(29/86), and 43.75%(28/64) in the PNALT, PIALT1, and PIALT2 groups, respectively. The degrees of inflammation and liver fibrosis were significantly higher in the PIALT groups than in the PNALT group(P < 0.05). No significant difference was found in the areas under the curve(AUCs) between APRI and FIB-4 in the PNALT group; however, significant differences were found between APRI and LSM, and between FIB-4 and LSM in the PNALT group(P < 0.05 for both). In the PIALT1 and PIALT2 groups, no significant difference(P > 0.05) was found in AUCs for all comparisons(P > 0.05 for all). In the overall patients, a significant difference in the AUCs was found only between LSM and APRI(P < 0.05).CONCLUSION APRI and FIB-4 are not the ideal noninvasive hepatic fibrosis markers for PNALT patients. LSM is superior to APRI and FIB-4 in PNALT patients because of the influence of liver inflammation and necrosis.You-Wen Tan Xing-Bei Zhou Yun Ye Cong He Guo-Hong Ge 2017World Journal of Gastroenterology2017,23,31:18
2Efficacy and safety of Firebird sirolimus-eluting stent in treatment of complex coronary lesions in Chinese patients: one-year clinical and eight-month angiographic outcomes from the FIREMAN registry显示文摘LI Yan LI Cheng-xiang WANG Hai-chang XU Bo FANG Wei-yi GE Jun-bo WANG Wei-min CHEN Jack-P SHEN Wen-kuang JIANG Hong CONG Hong-liang PU Xiao-qun QIN Yong-wen JIN Hui-gen CAO Yu FIREMAN Investigators 2011Chinese Medical Journal2011,,6:17
3Chemical characteristics of haze particles in Xi'an during Chinese Spring Festival: Impact of fireworks burning显示文摘Fireworks burning releases massive fine particles and gaseous pollutants, significantly deteriorating air quality during Chinese Lunar New Year(LNY) period. To investigate the impact of the fireworks burning on the atmospheric aerosol chemistry, 1-hr time resolution of PM_(2.5) samples in Xi'an during the winter of 2016 including the LNY were collected and detected for inorganic ions, acidity and liquid water content(LWC) of the fine aerosols. PM_(2.5) during the LNY was 167 ± 87 μg/m^3, two times higher than the China National Ambient Air Quality Standard(75 μg/m^3). K^+(28 wt.% of the total ion mass) was the most abundant ion in the LNY period, followed by SO_4^(2-)(25 wt.%) and Cl-(18 wt.%). In contrast, NO_3^-(34 wt.%) was the most abundant species in the haze periods(hourly PM32-2.5> 75 μg/m), followed by SO_4(29.2 wt.%) and NH_4^+(16.3 wt.%), while SO_4^(2-)(35 wt.%) was the most abundant species in the clean periods(hourly PM_(2.5)< 75 μg/m^3), followed by NO_3^-(23.1 wt.%) and NH_4^+(11 wt.%). Being different from the acidic nature in the non-LNY periods, aerosol in the LNY period presented an alkaline nature with a pH value of 7.8 ± 1.3. LWC during the LNY period showed a robust linear correlation with K_2SO_4 and KCl, suggesting that aerosol hygroscopicity was dominated by inorganic salts derived from fireworks burning. Analysis of correlations between the ratios of NO--3/SO_4^(2-) and NH_4^+/SO_4^(2-) indicated that heterogeneous reaction of HNO_3 with NH_3 was an important formation pathway of particulate nitrate and ammonium during the LNY period.Can Wu Gehui Wang Jiayuan Wang Jianjun Li Yanqin Ren Lu Zhang Cong Cao Jin Li Shuagshuang Ge Yuning Xie Xinpei Wang Guoyan Xue 2018Journal of Environmental Sciences2018,30,9:10
4Special AT-rich sequence-binding protein 1 promotes cell growth and metastasis in colorectal cancer显示文摘AIM: To evaluate the expression of special AT-rich sequence-binding protein 1 (SATB1 ) gene in colorectal cancer and its role in colorectal cancer cell proliferation and invasion.METHODS: Immunohistochemistry was used to detect the protein expression of SATB1 in 30 colorectal cancer (CRC) tissue samples and pair-matched adjacent nontumor samples. Cell growth was investigated after enhancing expression of SATB1. Wound-healing assay and Transwell assay were used to investigate the impact of SATB1 on migratory and invasive abilities of SW480 cells in vitro . Nude mice that received subcutaneous implantation or lateral tail vein were used to study the effects of SATB1 on tumor growth or metastasis in vivo . RESULTS: SATB1 was over-expressed in CRC tissues and CRC cell lines. SATB1 promotes cell proliferation and cell cycle progression in CRC SW480 cells. SATB1 over-expression could promote cell growth in vivo . In addition, SATB1 could significantly raise the ability of cell migration and invasion in vitro and promote the ability of tumor metastasis in vivo . SATB1 could up-regulate matrix metalloproteases 2, 9, cyclin D1 and vimentin, meanwhile SATB1 could down-regulate E-cadherin in CRC. CONCLUSION: SATB1 acts as a potential growth and metastasis promoter in CRC. SATB1 may be useful as a therapeutic target for CRC.Xue-Feng Fang Zhi-Bo Hou Xin-Zheng Dai Cong Chen Jing Ge Hong Shen Xiao-Feng Li Li-Ke Yu Ying Yuan 2013World Journal of Gastroenterology2013,19,15:9
5Laparoscopic distal pancreatectomy with or without splenectomy: spleen-preservation does not increase morbidity显示文摘BACKGROUND: The indications for laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and its morbidity compared with laparoscopic distal pancreatectomy with splenectomy (LDPS) are ill-defined. This study aimed to share the indications for spleen-preservation and investigate the safety and outcome of LSPDP at our institution. METHODS: A retrospective review of patients who were scheduled to receive laparoscopic surgery for distal pancreatic lesions was conducted. The indications, surgical procedures, intra-operative data, and outcomes of the two procedures were collected and compared by statistical analysis. RESULTS: LDPS and LSPDP were successfully performed in 16 and 21 patients respectively, whereas they were converted to open surgery in 9 patients. There were no significant differences in age, gender, operation time, blood loss, and conversion rate between the LDPS and LSPDP groups. The mean tumor size showed an inter-group difference (5.05 vs 2.53 cm, P<0.001). There were no significant differences in complication and morbidity rates between the two groups. All patients remained alive without recurrence during a follow-up of 9 to 67 months (median 35).CONCLUSION: LSPDP has a morbidity and outcome comparable to LDPS.Yu-Pei Zhao, Xiao Du, Meng-Hua Dai, Tai-Ping Zhang, Quan Liao, Jun-Chao Guo, Lin Cong ,Ge Chen Department of General Surgery, Peking Union Medical College Hospital,Chinese Academy of Medical Sciences and Peking Union Medical College,Beijing 100730, China 2012Hepatobiliary & Pancreatic Diseases International2012,11,5:8
6Microwave ablation of primary breast cancer inhibits metastatic progression in model mice via activation of natural killer cells显示文摘Surgery is essential for controlling the symptoms and complications of stage IV breast cancer.However,locoregional treatment of primary tumors often results in distant progression,including lung metastasis,the most common type of visceral metastasis.As a minimally invasive thermal therapy,microwave ablation(MWA)has been attempted in the treatment of breast cancer,but the innate immune response after MWA has not yet been reported.Using two murine models of stage IV breast cancer,we found that MWA of primary breast cancer inhibited the progression of lung metastasis and improved survival.NK cells were activated after MWA of the primary tumor and exhibited enhanced cytotoxic functions,and the cytotoxic pathways of NK cells were activated.Depletion experiments showed that NK cells but not CD4+or CD8+T cells played a pivotal role in prolonging survival.Then,we found that compared with surgery or control treatment,MWA of the primary tumor induced completely different NK-cell-related cytokine profiles.Macrophages were activated after MWA of the primary tumor and produced IL-15 that activated NK cells to inhibit the progression of metastasis.In addition,MWA of human breast cancer stimulated an autologous NK-cell response.These results demonstrate that MWA of the primary tumor in metastatic breast cancer inhibits metastatic progression via the macrophage/IL-15/NK-cell axis.MWA of the primary tumor may be a promising treatment strategy for de novo stage IV breast cancer,although further substantiation is essential for clinical testing.Muxin Yu Hong Pan Nan Che Li Li Cong Wang Yue Wang Ge Ma Mengjia Qian Jiawei Liu Mingjie Zheng Hui Xie Lijun Ling Yi Zhao Xiaoxiang Guan Qiang Ding Wenbin Zhou Shui Wang 2021Cellular & Molecular Immunology2021,18,9:5
7Enhanced CO catalytic oxidation by Sr reconstruction on the surface of LaxSr1-xCoO3-δ显示文摘Surface electronic structure of solid materials plays a critical role in heterogeneous catalysis. However,surface chemical composition of the perovskite oxides is usually dominated by segregated A-site cations and the amount of oxygen vacancies is relatively low, which seriously restricts their catalytic oxidation property. Here, we prepare perovskite La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7) with different Sr doping amount and experiment results show that perovskite LSCO with higher content of surface Sr possesses more oxygen vacancies and better catalytic activity. On this basis, we develop a new experimental strategy to create more surface oxygen vacancies to promote their CO catalytic activity. In this method, we use high active hydrogen atoms(BH^(4-)) as reductant to realize surface in-situ chemical composite modification of La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7), which causes their surface reconstruction(surface Sr enrichment).The regulation mainly focuses on the atomic layer level without damaging their bulk phase structure.Different from traditional high temperature annealing under reducing atmosphere, this method is high-efficiency, green and controllable. Furthermore, we study the surface reconstruction process and demonstrated that it is atomic layer engineering on the surface of La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7) by X-ray photoelectron spectroscopy(XPS) and X-ray absorption fine structure(XAFS). Our experiment results also show that these samples treated by this method exhibit superior activity for CO oxidation compared with original samples.Xiyang Wang Keke Huang Jingyu Qian Yingge Cong Chengda Ge Shouhua Feng 2017Science Bulletin2017,62,9:5
8Effectiveness of Integrative Medicine Therapy on Coronary Artery Disease Prognosis: A Real-World Study显示文摘Objective: To evaluate the effectiveness of integrative medicine(IM) on patients with coronary artery disease(CAD) and investigate the prognostic factors of CAD in a real-world setting. Methods: A total of 1,087 hospitalized patients with CAD from four hospitals in Beijing, China were consecutively selected between August 2011 and February 2012. The patients were assigned to two groups based on the treatment: Chinese medicine(CM) plus conventional treatment, i.e., IM therapy(IM group); or conventional treatment alone(CT group). The endpoint was major adverse cardiac events [MACE; including cardiac death, myocardial infarction(MI), and revascularization]. Results: A total of 1,040 patients finished the 2-year follow-up. Of them, 49.4%(514/1,040) received IM therapy. During the 2-year follow-up, the total incidence of MACE was 11.3%. Most of the events involved revascularization(9.3%). Cardiac death/MI occurred in 3.0% of cases. For revascularization, logistic stepwise regression analysis revealed that age 65 years [odds ratio(OR), 2.224], MI(OR, 2.561), diabetes mellitus(OR, 1.650), multi-vessel lesions(OR, 2.554), baseline high sensitivity C-reactive protein level 3 mg/L(OR, 1.678), and moderate or severe anxiety/depression(OR, 1.849) were negative predictors(P<0.05); while anti-platelet agents(OR, 0.422), β-blockers(OR, 0.626), statins(OR, 0.318), and IM therapy(OR, 0.583) were protective predictors(P<0.05). For cardiac death/MI, age 65 years(OR, 6.389) and heart failure(OR, 7.969) were negative predictors(P<0.05), while statin use(OR, 0.323) was a protective predictor(P<0.05) and IM therapy showed a beneficial tendency(OR, 0.587), although the difference was not statistically significant(P=0.218). Conclusion: In a real-world setting, for patients with CAD, IM therapy was associated with a decreased incidence of revascularization and showed a potential benefit in reducing the incidence of cardiac death or MI.ZHAO Kang TIAN Jin-fan ZHAO Cong YUAN Fei GAO Zhu-ye LI Li-zhi LIU Hong-xu WANG Xian GE Chang-jiang LU Shu-zheng 2019Chinese Journal of Integrative Medicine2019,25,1:5

10Broadband, sensitive and spectrally distinctive SnS_(2) nanosheet/PbS colloidal quantum dot hybrid photodetector显示文摘Photodetectors convert photons into current or voltage outputs and are thus widely used for spectroscopy,imaging and sensing.Traditional photodetectors generally show a consistent-polarity response to incident photons within their broadband responsive spectrum.Here we introduced a new type of photodetector employing SnS_(2) nanosheets sensitized with PbS colloidal quantum dots(CQDs)that are not only sensitive(~105AW−1)and broadband(300–1000 nm)but also spectrally distinctive,that is,show distinctive(positive or negative)photoresponse toward incident photons of different wavelengths.A careful mechanism study revealed illumination-modulated Schottky contacts between SnS_(2) nanosheets and Au electrodes,altering the photoresponse polarity toward incident photons of different wavelengths.Finally,we applied our SnS_(2) nanosheet/PbS CQDs hybrid photodetector to differentiate the color temperature of emission from a series of white light-emitting diodes(LEDs),showcasing the unique application of our novel photodetectors.Liang Gao Chao Chen Kai Zeng Cong Ge Dun Yang Haisheng Song Jiang Tang 2016Light(Science & Applications)2016,5,1:4
11Severe human infection with a novel avian-origin influenza A(H7N4) virus显示文摘Human infections with influenza H7 subtypes, such as H7N9, have raised concerns worldwide. Here, we report a human infection with a novel influenza A(H7N4) virus. A 68 years-old woman with cardiovascular and cholecystic comorbidities developed rapidly progressed pneumonia with influenza-like-illness as initial symptom, recovered after 23 days-hospitalization including 8 days in ICU. Laboratory indicators for liver and blood coagulation dysfunction were observed. Oseltamivir phosphate, glucocorticoids and antibiotics were jointly implemented, with nasal catheterization of oxygen inhalation for this patient.We obtained the medical records and collected serial respiratory and blood specimens from her. We collected throat, cloacal and/or feces samples of poultry and wild birds from the patient's backyard, neighborhood, local live poultry markets(LPMs) and the nearest lake. All close contacts of the patient were followed up and sampled with throat swabs and sera. Influenza viruses and other respiratory pathogens were tested by real-time RT-PCR, viral culturing and/or sequencing for human respiratory and bird samples. Micro-neutralizing assay was performed for sera. A novel reassortant wild bird-origin H7N4 virus is identified from the patient and her backyard poultry(chickens and ducks) by sequencing, which is distinct from previously-reported avian H7N4 and H7N9 viruses. At least four folds increase of neutralizing antibodies to H7N4 was detected in her convalescent sera. No samples from close contacts, wild birds or other poultry were tested positive for H7N4 by real-time RT-PCR.Xiang Huo Lun-biao Cui Cong Chen Dayan Wang Xian Qi Ming-hao Zhou Xiling Guo Fengming Wang William J.

12Risk factors for the occurrence of insulinoma: a case-control study显示文摘BACKGROUND: The etiology of insulinoma is poorly understood. Few studies investigated the possible roles of environmental factors and lifestyle in the pathogenesis of insulinoma. The aim of this study is to identify risk factors associated with occurrence of insulinoma in the Chinese population. METHODS: This study consisted of 196 patients with insulinoma and 233 controls. Demographic information of the patients and controls and risk factors of the disease were analyzed. Univariate and unconditional multivariable logistic regression analyses were made to estimate odds ratios (ORs) and possible risk factors. RESULTS: Approximately 68.88% (135/196) of the patients were from rural areas in contrast to 10.30% (24/233) of the controls (P<0.0001). This difference was confirmed by the multivariate analysis (OR=4.950; 95% CI: 2.928-8.370). Family history of pancreatic endocrine tumor (OR=16.754; 95% CI: 2.125-132.057) and other cancers (OR=2.360; 95% CI: 1.052-5.291) was also related to a high-risk population of insulinoma. CONCLUSION: Rural residents or people who have a family history of pancreatic endocrine tumor and other cancers are a high-risk population of insulinoma.Han-Xiang Zhan Lin Cong Yu-Pei Zhao Tai-Ping Zhang Ge Chen 2013Hepatobiliary & Pancreatic Diseases International2013,12,3:3

14Extracellular matrix-derived mechanical force governs breast cancer cell stemness and quiescence transition through integrin-DDR signaling显示文摘The extracellular matrix(ECM)serves as signals that regulate specific cell states in tumor tissues.Increasing evidence suggests that extracellular biomechanical force signals are critical in tumor progression.In this study,we aimed to explore the influence of ECM-derived biomechanical force on breast cancer cell status.Experiments were conducted using 3D collagen,fibrinogen.Cong Li Shi Qiu Xiaohan Liu Fengzhu Guo Jingtong Zhai Zhijun Li Linghui Deng Liming Ge Haili Qian Lu Yang Binghe Xu 2023Signal Transduction and Targeted Therapy2023,8,7:2
15Genome assembly of the maize inbred line A188 provides a new reference genome for functional genomics显示文摘The current assembled maize genomes cannot represent the broad genetic diversity of maize germplasms.Acquiring more genome sequences is critical for constructing a pan-genome and elucidating the linkage between genotype and phenotype in maize.Here we describe the genome sequence and annotation of A188,a maize inbred line with high phenotypic variation relative to other lines,acquired by single-molecule sequencing and optical genome mapping.We assembled a 2210-Mb genome with a scaffold N50 size of 11.61 million bases(Mb),compared to 9.73 Mb for B73 and 10.2 Mb for Mo17.Based on the B73_Ref Gen_V4 genome,295 scaffolds(2084.35 Mb,94.30%of the final genome assembly)were anchored and oriented on ten chromosomes.Comparative analysis revealed that~30%of the predicted A188 genes showed large structural divergence from B73,Mo17,and W22 genomes,which causes high protein divergence and may lead to phenotypic variation among the four inbred lines.As a line with high embryonic callus(EC)induction capacity,A188 provides a convenient tool for elucidating the molecular mechanism underlying the formation of EC in maize.Combining our new A188 genome with previously reported QTL and RNA sequencing data revealed eight genes with large structural variation and two differentially expressed genes playing potential roles in maize EC induction.Fei Ge Jingtao Qu Peng Liu Lang Pan Chaoying Zou Guangsheng Yuan Cong Yang Guangtang Pan Jianwei Huang Langlang Ma Yaou Shen 2022The Crop Journal2022,10,1:2
16Human umbilical cord mesenchymal stem cells for psoriasis:a phase 1/2a,single-arm study显示文摘Psoriasis is a common,chronic immune-mediated systemic disease that had no effective and durable treatment.Mesenchymal stem cells(MSCs)have immunomodulatory properties.Therefore,we performed a phase 1/2a,single-arm clinical trial to evaluate the safety and efficacy of human umbilical cord-derived MSCs(UMSCs)in the treatment of psoriasis and to preliminarily explore the possible mechanisms.Seventeen patients with psoriasis were enrolled and received UMsC infusions.Adverse events,laboratory parameters,PASl,and PGA were analyzed.We did not observe obvious side effects during the treatment and 6-month follow-up.A total of 47.1%(8/17)of the psoriasis patients had at least 40%improvement in the PASl score,and 17.6%(3/17)had no sign of disease or minimal disease based on the PGA score.And the efficiency was 25%(2/8)for males and 66.7%(6/9)for females.After UMSC transplantation(UMSCT),the frequencies of Tregs and CD4^(+)memory T cells were significantly increased,and the frequencies of T helper(Th)17 and CD4^(+)naive T cells were significantly decreased in peripheral blood(PB)of psoriasis patients.And all responders showed significant increases in Tregs and CD4^(+)memory T cells,and significant decreases in Th17 cells and serum IL-17 level after UMsCT.And baseline level of Tregs in responders were significantly lower than those in nonresponders.In conclusion,allogeneic UMSCT is safe and partially effective in psoriasis patients,and level of Tregs may be used as a potent biomarker to predict the clinical efficacy of UMSCT.Trial registration Clinical Trials NCT03765957.Lamei Cheng Siqi Wang Cong Peng Xiao Zou Chao Yang Hua Mei Chuang Li Xian Su Na Xiao Qi Ouyang Mi Zhang Qiaolin Wang Yan Luo Minxue Shen Qun Qin Honglin Wang Wu Zhu Guangxiu Lu Ge Lin Yehong Kuang Xiang Chen 2022Signal Transduction and Targeted Therapy2022,7,9:2
17Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population:Findings from the China Cardiometabolic Disease and Cancer Cohort(4C)Study显示文摘Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.ZHU Yuan Yue ZHENG Rui Zhi WANG Gui Xia CHEN Li SHI Li Xin SU Qing XU Min XU Yu CHEN Yu Hong YU Xue Feng YAN Li WANG Tian Ge ZHAO Zhi Yun QIN Gui Jun WAN Qin CHEN Gang GAO Zheng Nan SHEN Fei Xia LUO Zuo Jie QIN Ying Fen HUO Ya Nan LI Qiang YE Zhen ZHANG Yin Fei LIU Chao WANG You Min WU Sheng Li YANG Tao DENG Hua Cong ZHAO Jia Jun CHEN Lu Lu MU Yi Ming TANG Xu Lei HU Ru Ying WANG Wei Qing NING Guang LI Mian LU Jie Li BI Yu Fang 2021Biomedical and Environmental Sciences2021,34,1:2
18Crotalaria ferruginea extract attenuates lipopolysaccharide-induced acute lung injury in mice by inhibiting MAPK/NF-κB signaling pathways显示文摘Objective:To evaluate the anti-inflammatory activity of Crotalaria ferruginea extract(CFE)and its mechanism.Methods:An intratracheal lipopolysaccharide(LPS)instillationinduced acute lung injury(ALI)model was used to study the antiinflammatory activity of CFE in vivo.The LPS-induced shock model was used to analyze the effect of CFE on survival.LPS-stimulated RAW264.7 cell model was used to investigate the anti-inflammatory activity of CFE in vitro and the effects on mitogen-activated protein kinase(MAPK)or nuclear factor-κB(NF-κB)signaling pathways.Results:CFE administration decreased the number of inflammatory cells,reduced the levels of tumor necrosis factor-α(TNF-α),monocyte chemotactic protein-1(MCP-1),interleukin-6(IL-6),and interferon-γ,and diminished protein content in the bronchoalveolar lavage fluid of mice.CFE also reduced lung wet-to-dry weight ratio,myeloperoxidase,and lung tissue pathological injury.CFE preadministration improved the survival rate of mice challenged with a lethal dose of LPS.CFE reduced LPS-activated RAW264.7 cells to produce nitric oxide,TNF-α,MCP-1,and IL-6.Furthermore,CFE inhibited nuclear translocation and phosphorylation of NF-κB P65,extracellular signal-regulated kinase,c-Jun N-terminal kinases,and P38 MAPKs.Conclusions:CFE exhibits potent anti-inflammatory activity in LPS-induced ALI mice,LPS-shock mice,and RAW264.7 cells,and its mechanism may be associated with the inhibition of NF-κB and MAPK signaling pathways.Crotalaria ferruginea may be a useful therapeutic drug for the treatment of ALI and other respiratory inflammations.Wei Pan Li-Ping Meng Jie Su Zheng-Biao Yang Wei-Feng Du Zhi-Wei Xu Yun-Xiang Chen Sheng Zhang Feng Xie Cong Xu Hong-Zhong Yang Wei-Hong Ge 2021Asian Pacific Journal of Tropical Biomedicine2021,11,11:2
19DTHMM based delay modeling and prediction for networked control systems显示文摘In the forward channel of a networked control system (NCS), by defining the network states as a hidden Markov chain and quantizing the network-induced delays to a discrete sequence distributing over a finite time interval, the relation between the network states and the network-induced delays is modelled as a discrete-time hidden Markov model (DTHMM). The expectation maximization (EM) algorithm is introduced to derive the maximumlikelihood estimation (MLE) of the parameters of the DTHMM. Based on the derived DTHMM, the Viterbi algorithm is introduced to predict the controller-to-actuator (C-A) delay during the current sampling period. The simulation experiments demonstrate the effectiveness of the modelling and predicting methods proposed.Shuang Cong Yuan Ge Qigong Chen Ming Jiang Weiwei Shang 2010Journal of Systems Engineering and Electronics2010,21,6:2
