1Review on Stress Corrosion and Corrosion Fatigue Failure of Centrifugal Compressor Impeller显示文摘Corrosion failure,especially stress corrosion cracking and corrosion fatigue,is the main cause of centrifugal compressor impeller failure.And it is concealed and destructive.This paper summarizes the main theories of stress corrosion cracking and corrosion fatigue and its latest developments,and it also points out that existing stress corrosion cracking theories can be reduced to the anodic dissolution(AD),the hydrogen-induced cracking(HIC),and the combined AD and HIC mechanisms.The corrosion behavior and the mechanism of corrosion fatigue in the crack propagation stage are similar to stress corrosion cracking.The effects of stress ratio,loading frequency,and corrosive medium on the corrosion fatigue crack propagation rate are analyzed and summarized.The corrosion behavior and the mechanism of stress corrosion cracking and corrosion fatigue in corrosive environments,which contain sulfide,chlorides,and carbonate,are analyzed.The working environments of the centrifugal compressor impeller show the behavior and the mechanism of stress corrosion cracking and corrosion fatigue in different corrosive environments.The current research methods for centrifugal compressor impeller corrosion failure are analyzed.Physical analysis,numerical simulation,and the fluid-structure interaction method play an increasingly important role in the research on impeller deformation and stress distribution caused by the joint action of aerodynamic load and centrifugal load.SUN Jiao CHEN Songying QU Yanpeng LI Jianfeng 2015Chinese Journal of Mechanical Engineering2015,28,2:14
2Effects of Temperature and Pressure on Stress Corrosion Cracking Behavior of 310S Stainless Steel in Chloride Solution显示文摘310S is an austenitic stainless steel for high temperature applications, having strong resistance of oxidation, hydrogen embrittlement and corrosion. Stress corrosion cracking(SCC) is the main corrosion failure mode for 310 S stainless steel. Past researched about SCC of 310 S primarily focus on the corrosion mechanism and influence of temperature and corrosive media, but few studies concern the combined influence of temperature, pressure and chloride. For a better understanding of temperature and pressure's effects on SCC of 310 S stainless steel, prepared samples are investigated via slow strain rate tensile test(SSRT) in different temperature and pressure in NACE A solution. The result shows that the SCC sensibility indexes of 310 S stainless steel increase with the rise of temperature and reach maximum at 10 MPa and 160℃, increasing by 22.3% compared with that at 10 MPa and 80 ℃. Instead, the sensibility decreases with the pressure up. Besides, the fractures begin to transform from the ductile fracture to the brittle fracture with the increase of temperature. 310 S stainless steel has an obvious tendency of stress corrosion at 10 MPa and 160℃ and the fracture surface exists cleavage steps, river patterns and some local secondary cracks, having obvious brittle fracture characteristics. The SCC cracks initiate from inclusions and tiny pits in the matrix and propagate into the matrix along the cross section gradually until rupture. In particular, the oxygen and chloride play an important role on the SCC of 310 S stainless steel in NACE A solution. The chloride damages passivating film, causing pitting corrosion, concentrating in the cracks and accelerated SSC ultimately. The research reveals the combined influence of temperature, pressure and chloride on the SCC of 310 S, which can be a guide to the application of 310 S stainless steel in super-heater tube.ZHONG Yunpan ZHOU Cheng CHEN Songying WANG Ruiyan 2017Chinese Journal of Mechanical Engineering2017,30,1:9
3How do Chinese medicines that tonify the kidney inhibit dopaminergic neuron apoptosis?显示文摘Wistar rats were intragastrically perfused with Chinese medicines used for tonifying the kidney.These included 0.180 g/mL of Herba Epimedii(Epimedium), Semen Cuscutae(Dodder Seed), or Herba Cistanches(Desertliving Cistanche), 0.04 mg/mL monoamine oxidase-B inhibitor selegiline,or distilled water for 14 consecutive days to prepare drug-containing serum or blank serum.MES23.5 cells in the logarithmic phase were cultured in media supplemented with 15%drug-containing serum for 24 hours, followed by incubation in culture solution containing 100 μmol/L H2O2for 3 hours. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) and flow cytometry results showed that all drug-containing serums improved the survival rate of H2O2-injured MES23.5 cells, inhibited pro-apoptotic FasL and caspase-3 expression, promoted anti-apoptotic Bcl-2 expression. However, drug-containing serums had little influence on Fas expression in H2O2-injured MES23.5 cells. Enzyme-linked immunosorbent assay results showed that serum containing Herba Cistanches or Herba Epimedii increased the expression of nerve growth factor,brain-derived neurotrophic factor, and glial cell line-derived neurotrophic factor in injured MES23.5cells; serum containing Semen Cuscutae only increased brain-derived neurotrophic factor expression; while expression of the above neurotrophic factors remained the same in cells treated with serum containing selegiline. These findings indicate that Chinese medicines used to tonify the kidney can protect nerve cells by regulating the expression of apoptosis-related factors and neurotrophic factors in MES23.5 cells.Shaogang Lin Shuifen Ye Jinmu Huang Yun Tian Yihui Xu Mengqi Wu Jingxia Wang Songying Wu Jing Cai 2013Neural Regeneration Research2013,8,30:9
4Garlic-derived compound S-allylmercaptocysteine inhibits hepatocarcinogenesis through targeting LRP6/Wnt pathway显示文摘Whether and how garlic-derived S-allylmercaptocysteine(SAMC) inhibits hepatocellular carcinoma(HCC) is largely unknown. In the current study, the role of low-density lipoprotein receptor(LDLR)-related protein 6(LRP6) in HCC progression and the anti-HCC mechanism of SAMC was examined in clinical sample, cell model and xenograft/orthotopic mouse models. We demonstrated that SAMC inhibited cell proliferation and tumorigenesis, while induced apoptosis of human HCC cells without influencing normal hepatocytes. SAMC directly interacted with Wnt-pathway co-receptor LRP6 on the cell membrane. LRP6 was frequently over-expressed in the tumor tissue of human HCC patients(66.7% of 48 patients) and its overexpression only correlated with the over-expression of β-catenin, but not with age, gender, tumor size, stage and metastasis. Deficiency or over-expression of LRP6 in hepatoma cells could partly mimic or counteract the anti-tumor properties of SAMC, respectively. In vivo administration of SAMC significantly suppressed the growth of Huh-7 xenograft/orthotopic HCC tumor without causing undesirable side effects. In addition, stable down-regulation of LRP6 in Huh-7 facilitated the anti-HCC effects of SAMC. In conclusion, LRP6 can be a potential therapeutic target of HCC. SAMC is a promising specific anti-tumor agent for treating HCC subtypes with Wnt activation at the hepatoma cell surface.Jia Xiao Feiyue Xing Yingxia Liu Yi Lv Xiaogang Wang Ming-Tat Ling Hao Gao Songying Ouyang Min Yang Jiang Zhu Yu Xia Kwok-Fai So George L.Tipoe 2018Acta Pharmaceutica Sinica B2018,8,4:6

17Binding of bacterial secondary messenger molecule c di-GMP is a STING operation显示文摘Initial skirmishes between the host and pathogen result in spillage of the contents of the bacterial cell.Amongst the spillage,the secondary messenger molecule,cyclic dimeric guanosine monophosphate(c di-GMP),was recently shown to be bound by stimulator of interferon genes(STING).Binding of c di-GMP by STING activates the Tank Binding Kinase(TBK1)mediated signaling cascades that galvanize the body’s defenses for elimi-nation of the pathogen.In addition to c di-GMP,STING has also been shown to function in innate immune re-sponses against pathogen associated molecular pat-terns(PAMPs)originating from the DNA or RNA of pathogens.The pivotal role of STING in host defense is exemplified by the fact that STING-/-mice die upon infection by HSV-1.Thus,STING plays an essential role in innate immune responses against pathogens.This opens up an exciting possibility of targeting STING for development of adjuvant therapies to boost the im-mune defenses against invading microbes.Similarly,STING could be targeted for mitigating the inflamma-tory responses augmented by the innate immune sys-tem.This review summarizes and updates our current understanding of the role of STING in innate immune responses and discusses the future challenges in de-lineating the mechanism of STING-mediated responses.Neil Shaw Songying Ouyang Zhi-Jie Liu 2013Protein & Cell2013,4,2:1
