1Effects of Fluoride on Lipid Peroxidation, DNA Damage and Apoptosis in Human Embryo Hepatocytes显示文摘Objective To investigate the effects of fluoride on lipid peroxidation, DNA damage and apoptosis in human embryo hepatocyte L-02 cells. Methods Lipid peroxide (LPO) level, reduced glutathione (GSH) content, DNA damage, apoptosis, and cell cycle analysis were measured after in vitro cultured L-02 cells were exposed to sodium fluoride at different doses (40 μg/mL, 80 μg/mL, and 160 μg/mL) for 24 hours. Results Fluoride caused an increase of LPO levels and a decrease of GSH content in L-02 cells. There appeared to be an obvious dose-effect relationship between the fluoride concentration and the observed changes. Fluoride also caused DNA damage and apoptosis and increased the cell number in S phase of cell cycle in the cells tested. There was a statistically significant difference in DNA damage and apoptosis when comparing the high dose of fluoride treated cells with the low dose of fluoride treated cells. Conclusion Fluoride can cause lipid peroxidation, DNA damage, and apoptosis in the L-02 cell experimental model and there is a significant positive correlation between fluoride concentration and these pathological changes.AI-GuoWANG TAOXIA QI-LONGCHU MINGZHANG FANGLIU XUE-MINCHEN KE-DIYANG 2004Biomedical and Environmental Sciences2004,17,2:18
2Multi-detector CT enterography with iso-osmotic mannitol as oral contrast for detecting small bowel disease显示文摘AIM: To assess the feasibility and usefulness of multi-detector CT enterography with orally administered iso-osmotic mannitol as negative contrast in demonstrating small bowel disease.METHODS: Thirteen volunteers and 38 patients with various kinds of small bowel disease were examined. We administered about 1 500 mL iso-osmotic mannitol as negative contrast agent and then proceeded with helical CT scanning on a Siemens Sensation 16 scanner. All volunteers and patients were interviewed about their tolerance of the procedure. Two radiologists postprocessed imaging data with MPR, thin MIP, VRT and INSPACE when necessary and then interpreted the scans,and adequacy of luminal distention was evaluated on a four-point scale. Demonstration of features of various kinds of small bowel disease was analyzed.RESULTS: The taste of iso-osmotic mannitol is good (slightly sweet) and acceptable by all. Small bowel distention was excellent and moderate in most volunteers and patients. CT features of many kinds of diseases such as tumors, Crohn's disease,and small bowel obstruction,etc. were clearly displayed.CONCLUSION: Multi-detector CT enterography with iso-osmotic mannitol as negative contrast to distend the small bowel is a simple, rapid, noninvasive and effective method of evaluating small bowel disease.Lian-HeZhang Shi-ZhengZhang Hong-JieHu MinGao MingZhang QianCao Qiao-weiZhang 2005World Journal of Gastroenterology2005,11,15:9
3China's New International Financial Strategy amid the Global Financial Crisis显示文摘中国政府促进了它的开车重建它在亚素数危机以后的国际金融策略在 2008 发展成一个全球金融危机。策略的主要目的是在外贸,跨边阶的大写的流动和外汇储备管理在美元上减少这个国家的依赖。策略能被划分成三级:国际钱的政体的人民币国际化,地区性的钱的合作和重建。到目前为止,中国政府在所有三级的应用程序做了很好。我们认为尽管有它面对的各种各样的挑战,中国政府应该以一种协调方式在一样的方向继续。MingZhang 2009China & World Economy2009,17,5:8
4Expert Recommendations for Tracheal Intubation in Critically Ill Patients with Noval Coronavirus Disease 2019显示文摘Coronavirus Disease 2019(COVID-19),caused by a novel coronavirus(SARS-Co V-2),is a highly contagious disease.It firstly appeared in Wuhan,Hubei province of China in December 2019.During the next two months,it moved rapidly throughout China.Most of the infected patients have mild symptoms including fever,fatigue and cough,but in severe cases,patients can progress rapidly and develop into acute respiratory distress syndrome,septic shock,metabolic acidosis and coagulopathy.The new coronavirus was reported to spread via droplets,contact and natural aerosols from human to human.Therefore,aerosol-producing procedures such as endotracheal intubation may put the anesthesiologists at high risk of nosocomial infections.In fact,SARSCo V-2 infection of anesthesiologists after endotracheal intubation for confirmed COVID-19 patients have been reported in hospitals in Wuhan.The expert panel of airway management in Chinese Society of Anaesthesiology has deliberated and drafted this recommendation,by which we hope to guide the performance of endotracheal intubation by frontline anesthesiologists and critical care physicians.During the airway management,enhanced droplet/airborne personal protective equitment(PPE)should be applied to the health care providers.A good airway assessment before airway intervention is of vital importance.For patients with normal airway,awake intubation should be avoided,and modified rapid sequence induction is strongly recommended.Sufficient muscle relaxant should be assured before intubation.For patients with difficult airway,good preparation of airway devices and detailed intubation plans should be made.Mingzhang Zuo Yuguang Huang Wuhua Ma Zhanggang Xue Jiaqiang Zhang Yahong Gong Lu Che 2020Chinese Medical Sciences Journal2020,35,2:7
5The insecticide resistance in stripped stem borer,Chilo suppressalis(Walker)显示文摘The stripped stem borer (SSB), Chilo suppressalis (Walker) is one of the major insect pests of rice in China. Chemical control has been a common practice in SSB management since 1950s. Insecticides used included BHC before 1983;organophosphorus insecticides (methyl-parathion, trichophon, methamidophos, and monocrotophos), and chlordimeform in mid-1970s-1980s; Shachongshuang (dimehypo) and Shachongdan (monousltap) since early 1980s. In recent years, SSB population and its damage to rice increased rapidly and failures on control has been reported. To find out the cause of failure and to put forward the suitable control methods, we studied the resistance of SSB to major insecticides used in China.CAO Mingzhang SHEN Jinliang LIU Xiaoyu Li Mei Dept of Pesticide Sci,College of Plant Protection,Nanjing Agri Univ,Nanjing 210095,China 2001Chinese Rice Research Newsletter2001,9,1:5

16DNA polymerase ξ:new insight into eukaryotic mutagenesis and mammalian embryonic development显示文摘Information about the mechanisms that generate mutationsin eukaryotes is likely to be useful for understanding humanhealth concerns, such as genotoxicity and cancer.Eukaryotic mutagenesis is largely the outcome of attacksby' endogenous and environmental agents. Except for DNArepair, cell cycle checkpoints and DNA damage avoidance,cells have also evolved DNA damage tolerance mechanism,by which lesion-targeted mutation might occur in thegenome during replication by specific DNA polymerases tobypass the lesions (translesion DNA synthesis, TLS), ormutation on undamaged DNA templates (untargetedmutation) might be induced. DNA polymerase ζ (poiζ),which was found firstly in budding yeast Saccharomycescerevisiae and consists of catalytic subunit scRev3 and stimulating subunit scRev7, has Received more attention in recent years. Poi ζ is a member of DNA polymerase δsubfamily, which belongs to DNA polymerase B family, and exists in almost all eukaryotes. Human homolog of the scRev3gene is located in chromosome region 6q21, and the mouse equivalent maps to chromosome 10, distal to the c-myb gene and close to the Macs gene. Alternative splicing, upstream out-of frame ATG can be found in yeast scRev3, mouse and human homologs. Furthermore, the sequence from 253-323 immediate upstream of the AUG initiator codon has the potential to form a stem-loop hairpin secondary structure in REV3 mRNA, suggesting that human REV3 protein may be expressed at low levels in human cells under normal growth conditions. The functional domain analysis showed that yeast Rev3-980 tyrosine in conserved region II is at the polymerase active site. Human REV3 amino acid residues 1 776-2 195 provide a REV7binding domain, and REV7 amino acid residues 1-211provide a bind domain for REV1, REV3 and REV7 itself.More interestingly, REV7 interacts with hMAD2 and therefore might function in the cell cycle control by affecting the activation of APC (anaphase promoting complex).Currently it has been known that poi ζ is involved in most spontaneous mutation, lesion-targeted mutation via TLS,chemical carcinogen induced untargeted mutation and somatic hypermutation of antibody genes in mammalian.In TLS pathway, polζ acts as a 'mismatch extender' with combination of other DNA polymerases, such as pol t. Unlike in yeast, it was found that pol ζ also functioned in mouse embryonic development more recently. It was hypothesized that the roles of pol ζ in TLS and cell cycle control might contribute to mouse embryonic lethality.FengZhu MingZhang 2003World Journal of Gastroenterology2003,9,6:1

20Observation of continental shelf wave propagating along the eastern Taiwan Strait during Typhoon Meranti 2016显示文摘This study is the fi rst to depict typhoon-induced continental shelf wave(CSW)propagation in the eastern Taiwan Strait(TWS)during the passage of Typhoon Meranti in 2016 using tidal gauge data and along-track satellite altimeter data.The strong amplitude response of sea level oscillations(within the range of 0.30–0.54 m)as a free,barotropic CSW after Meranti,which impacted the TWS,was clearly detected in time and frequency(in bands of 64–81 h)using wavelet and cross-wavelet analyses.The measured group and phase speeds were consistent with the dispersion curves for CSW with the fi rst-mode derived from the cross-shelf sections of the eastern TWS,with the mean speeds reaching 3 and 5.6±0.7 m/s,respectively.Coincidentally,the typhoon-induced sea level anomaly(SLA)was also captured by the satellite altimeter before this CSW entered into the TWS.Using the theoretical cross-shore CSW modes to fi t the SLA data,the results indicated that the fi rst three wave modes can interpret this CSW event appeared in the southern TWS very well,with the fi rst mode being the dominant one.Junqiang SHEN Shanwu ZHANG Junpeng ZHANG Mingzhang ZENG Wendong FANG 2021Journal of Oceanology and Limnology2021,39,1:1
