| 1 | Real-time State Monitoring During Switching Mode Transitions in High Power Three-level Inverters显示文摘大功率多电平逆变器近年来在实际工业生产中得到越来越广泛的应用。多电平逆变器由于结构复杂,采用元器件较多,因此在设计和实验中,实现各个工作状态下运行参数的同步监测和分析较为困难。本文针对大功率三电平逆变器,实现开关动态特性的在线测试,在此基础上,进一步研究三电平逆变器在开关状态变化时理论与实际负载运行工况下电路拓扑的转换变化规律。通过全电路电气参数和元器件状态的实时监测,发现在三电平逆变器非正常运行状态下开关转换时额外电应力,同时,深入研究在实际工况运行条件非正常状态下该额外电应力出现的机理和原因,为三电平逆变器的故障诊断提供了参考,对于设计高可靠性的多电平逆变器系统有一定的理论和现实意义。 | HE Xiangning WU Yansong YANG Bingjian WANG Jun DENG Yan | 2012 | 中国电机工程学报2012,32,30: | 8 |
| 2 | Galectin-3-centered paracrine network mediates cardiac inflammation and fibrosis upon β-adrenergic insult显示文摘Rapid over-activation of β-adrenergic receptors (β-AR) following acute stress initiates cardiac inflammation and injury by activating interleukin-18 (IL-18),however,the process of inflammation cascades has not been fully illustrated.The present study aimed to determine the mechanisms of cardiac inflammatory amplification following acute sympathetic activation.With bioinformatics analysis,galectin-3 was identified as a potential key downstream effector of β-AR and IL-18 activation.The serum level of galectin-3 was positively correlated with norepinephrine or IL-18 in patients with chest pain.In the heart of mice treated with β-AR agonist isoproterenol (ISO,5 mg kg^(-1)),galectin-3 expression was upregulated markedly later than IL-18 activation,and Nlrp3^(-/-)and Il18^(-/-)mice did not show ISO-induced galectin-3 upregulation.It was further revealed that cardiomyocyte-derived IL-18 induced galectin-3 expression in macrophages following ISO treatment.Moreover,galectin-3deficiency suppressed ISO-induced cardiac inflammation and fibrosis without blocking ISO-induced IL-18 increase.Treatment with a galectin-3 inhibitor,but not a β-blocker,one day after ISO treatment effectively attenuated cardiac inflammation and injury.In conclusion,galectin-3 is upregulated to exaggerate cardiac inflammation and injury following acute β-AR activation,a galectin-3 inhibitor effectively blocks cardiac injury one day after β-AR insult. | Guomin Hu Jimin Wu Huijun Gu Xiangning Deng Wenli Xu Shan Feng Shuaixing Wang Yao Song Zhengda Pang Xiuling Deng Aleksandr E.Vendrov Nageswara R.Madamanchi Marschall S.Runge Xinyu Wang Youyi Zhang Han Xiao Erdan Dong | 2023 | Science China(Life Sciences)2023,66,5: | 3 |
| 3 | Autophagy mediates the secretion of macrophage migration inhibitory factor from cardiomyocytes upon serum-starvation显示文摘Macrophage migration inhibitory factor(MIF) is an inflammatory cytokine. It is elevated early in the blood of acute myocardial infarction patients. However, it is unclear whether and how MIF is released. This study investigated the cellular source and mechanism of MIF release from hearts. An ischemia-mimic treatment induced the secretion of MIF from neonatal rat cardiomyocytes but not from fibroblasts. The treatment did not cause significant leakage of lactate dehydrogenase, suggesting that ischemia induced the MIF secretion without causing severe cell damage. Plasma samples from patients with acute chest pain at the emergency department were collected for the detection of MIF. MIF levels in patients with acute coronary syndrome(ACS)increased early, when cardiac injury markers were not yet elevated, suggesting that ischemia can induce MIF secretion before the occurrence of severe myocardial damage. Serum-starvation caused MIF secretion from rat cardiomyocytes and Langendorffperfused rat hearts. The secretion was suppressed by the inhibition of autophagy by inhibitors or by silencing of Atg5. In conclusion, serum-starvation induces the secretion of MIF from cardiomyocytes via autophagy dependent pathway. Clarifying the mechanism of MIF secretion will be helpful for its application in the early diagnosis and treatment of ACS. | Jimin Wu Xiangning Deng Juan Gao Wei Gao Han Xiao Xinyu Wang Youyi Zhang | 2019 | Science China(Life Sciences)2019,62,8: | 2 |
| 4 | Differential expression of bone morphogenetic protein 5 in human lung squamous cell carcinoma and adenocarcinoma显示文摘骨头形态基因的蛋白质(BMP ) 在肿瘤房间增长,转移,和侵略起重要作用。然而,在有 non-small-cell 肺癌症(NSCLC ) 和他们与 NSCLC 致病的关联的病人的 BMP 的表示模式还没被检验。在这研究,在 NSCLC 纸巾的 BMP 家庭成员的 mRNA 层次被分析,结果证明分别地, BMP5 和 BMP7 的 mRNA 层次与在相应 noncancerous 纸巾的那些相比在肿瘤纸巾显著地下面调整、起来调整。有趣地, BMP5 的 mRNA 水平在肺比那在肺腺癌纸巾是显著地更高的有鳞的房间癌纸巾。而且,从 immunohistochemistry 分析的结果比在肺在肺腺癌证实了 BMP5 蛋白质的更强壮的表示有鳞的房间癌。我们的调查结果建议 BMP5 可能为有 NSCLC 的病人是潜在的预示的 biomarker 或治疗学的目标。 | Taoran Deng Dandan Lin Man Zhang Qingchuan Zhao Weina Li Bo Zhong Yu Deng Xiangning Fu | 2015 | Acta Biochimica et Biophysica Sinica2015,47,7: | 2 |

| 7 | 用于全麻食管重建术患者新的胃管置入法(英文)显示文摘Objective: We are describing a novel technique to insert nasogastric tube(NGT) in the anesthetized patients during cervical esophageal reconstruction. Methods: Forty patients with mid and upper esophageal tumor enrolled into this study were randomly allocated into two groups(the control group, group C and the novel method group, group N). All the patients were applied mechanical anastomosis to finish the cervical esophageal reconstruction. The procedure of NGT insertion for group C use the conventional method; well, the group N use the novel technique. Results: All the patients in group N had been finished the NGT insertion in the first attempt, and the total time for insertion was(5.05 ± 1.15) mins; on the contrary, for the group C, duration of insertion(min) was(24.45 ± 5.23) mins, and the successful rate of NGT insertion in the first attempt was 40%(P < 0.05); no one in group N had coiling/kinking, and 6/20(30%) in group C had it(P = 0.020). The complication rate of bleeding between the two group had no significant difference. Conclusion: For the patient with mid and upper esophageal tumor who need cervical esophageal reconstruction, this novel method can save the NGT insertion time, and make it easier with higher successful rate. | Ruijie Zhang Yu Deng Shengling Fu Yixin Cai Ni Zhang Xiangning Fu | 2014 | The Chinese-German Journal of Clinical Oncology2014,13,11: | 0 |
