1The Relationship between Glucose Excursion and Cognitive Function in Aged Type 2 Diabetes Patients显示文摘Objective Evidence suggests that type 2 diabetes (T2DM) is associated with an increased risk of dementia and that glucose variability is an independent risk factor for diabetic complications.This study investigated the relationship between glucose excursion and cognitive function in aged T2DM patients.Methods A total of 248 aged T2DM patients wore a continuous glucose monitoring system (CGMS) for 3 days in order to evaluate glucose excursion,including mean amplitude of glycemic excursions (MAGE) and mean of daily difference (MODD).All subjects were evaluated with a number of accepted cognitive function tests,including themini‐mental status examination (MMSE).The relationship between MAGE and MODD and performance on these cognitive tests was assessed.Results The MAGE and MMSE score were negatively correlated,likewise with the correlation between MODD and MMSE.Liner multivariate regression analysis showed that MAGE and MODD were also negatively related to MMSE independent of age,sex,glycemic control,hypertension,smoking,or coronary heart disease history.Conclusion Glucose excursion is related to cognitive function in aged T2DM patients.Elevated glucose excursion decreased the MMSE score,which reflects general cognitive function.Thus,therapy aimed at controlling glucose excursion may be beneficial for maintaining cognitive function in aged T2DM patients.ZHONG Yuan ZHANG Xiao Yan MIAO Ya ZHU Jie Hua YAN Hong WANG Bei Yun JIN Jun HU Ting Jun JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:34
2Comparison of parathyroid hormone (1-34) and elcatonin in postmenopausal women with osteoporosis: an 18-month randomized, multicenter controlled trial in China显示文摘LI Ying XUAN Miao WANG Bo YANG Jun ZHANG Hong ZHANG Xiu-zhen GUO Xiao-hui Lü Xiao-feng XUE Qing-yun YANG Gang-yi JI Qiu-he LIU Zhi-min LI Cheng-jiang WU Tian-feng SHENG Zheng-yan LI Peng-qiu TONG Jiu-cui 2013Chinese Medical Journal2013,,3:24
3Ambient air quality trends and driving factor analysis in Beijing, 1983–2007显示文摘The rapid development in Beijing, the capital of China, has resulted in serious air pollution problems. Meanwhile great efforts have been made to improve the air quality, especially since 1998. The variation in air quality under the interaction of pollution and control in this mega city has attracted much attention. We analyzed the changes in ambient air quality in Beijing since the 1980's using the Daniel trend test based on data from long-term monitoring stations. The results showed that different pollutants displayed three trends: a decreasing trend, an increasing trend and a flat trend. SO2, dustfall, B[a]P, NO2 and PM10 fit decreasing trend pattern, while NOx showed an increasing trend, and CO, ozone pollution, total suspended particulate (TSP), as well as Pb fit the flat trend. The cause of the general air pollution in Beijing has changed from being predominantly related to coal burning to mixed traffic exhaust and coal burning related pollution. Seasonally, the pollution level is typically higher during the heating season from November to the following March. The interaction between pollution sources change and implementation of air pollution control measures was the main driving factor that caused the variation in air quality. Changes of industrial structure and improved energy effciency, the use of clean energy and preferred use of clean coal, reduction in pollution sources, and implementation of advanced environmental standards have all contributed to the reduction in air pollution, particularly since 1998.Ju Zhang Zhiyun Ouyang Hong Miao Xiaoke Wang 2011Journal of Environmental Sciences2011,23,12:22
4Simultaneous Determination of Melamine, Ammelide, Ammeline, and Cyanuric Acid in Milk and Milk Products by Gas Chromatography-tandem Mass Spectrometry显示文摘Objective To develop an analytical method for simultaneously qualitative and quantitative determination of melamine and triazine-related by-products including ammelide, ammeline, and cyanuric acid in milk and milk products by gas chromatography- tandem mass spectrometry (GC-MS/MS). Methods Melamine and triazine-related by-products namely ammelide, ammeline and cyanuric acid in the samples were extracted in a solvent mixture of diethylamine, water, and acetonitrile (10:40:50, V/V/V). After centrifugation, an aliquot of the supernatant was evaporated to dryness under a gentle stream of nitrogen gas, and then melamine and triazine-related by-products were derivatized using BSTFA with 1% TMCS. The derivatives of melamine and its analogues were determined by gas chromatography/ tandem mass spectrometry using multiple reactional monitoring (MRM) with 2, 6-Diamino-4-chloropyrimidine (DACP) being used as an internal standard. Results The linear detectable ranges were from 0.004 mg/kg to 1.6 mg/kg for melamine, ammelide, ammeline, and cyanuric acid with a correlation coefficient no less than 0.999. The recovery rates of the four compounds in spiked blank milk powder at concentrations 0.5, 1, 2 mg/kg were between 61.4%-117.2%, and the relative standard deviation was no more than 11.5% (n=6). The detection limits of melamine, ammelide, ammeline and cyanuric acid in milk powder were 0.002 mg/kg with a ratio of signal to noise of 3. Conclusion This GC-MS/MS method for simultaneous determination of melamine, ammelide, ammeline, and cyanuric acid in milk and milk products is sensitive and specific.HONG MIAO SAI FAN YONG-NING WU LEI ZHANG PING-PING ZHOU JING-GUANG LI HUI-JING CHEN AND YUN-FENG ZHAO 2009Biomedical and Environmental Sciences2009,22,2:21

7Numerical Calculation and Experimental Research on Residual Stresses in Precipitation-hardening Layer of NAK80 Steel for Shot Peening显示文摘Shot peening can improve fatigue strength of materials by creating compressive residual stress field in their surface layers,and offers a protection against crack initiation and propagation,corrosion,etc.And fatigue fracture and stress corrosion cracking of NAK80 steel parts are improved effectively.Currently there lacks in-depth research in which the beneficial effect of the residual stress may be offset by the surface damage associated with shot peening,especially in terms of the research on the effective control of shot peening intensity.In order to obtain the surface residual stress field of NAK80 steel after shot peening,the samples are shot peened by pneumatic shot peening machine with different rules.The residual stress in the precipitation-hardening layer of NAK80 steel is measured before and after a shot peening treatment by X-ray diffraction method.In order to obtain true residual stress field,integral compensation method is used to correct results.By setting up analytical model of the residual stress in the process of shot peening,the surface residual stress is calculated after shot peening,and mentioning the reason of errors occurred between calculated and experimental residual stresses,which is mainly caused by the measurement error of the shoot arc height.At the same time,micro hardness,microstructure and roughness in the precipitation-hardening layer of NAK80 steel before and after shot peening were measured and surveyed in order to obtain the relation between shot peening strength and surface quality in the precipitation-hardening layer.The results show that the surface quality of NAK80 steel is significantly improved by shot peening process.The over peening effect is produced when the shot peening intensity is too high,it is disadvantageous to improve sample's surface integrity,and leading to reduce the fatigue life.When arc high value of optimal shot peening is 0.40 mm,the surface quality is the best,and the depth of residual stress in the precipitation-hardening layer reaches to about 450 μm.Numerical calculation is very useful to define the process parameters when a specific residual stress profile is intended,either to quantify the benefits on a specific property like fatigue life or to help on modeling a forming process like shot peen forming.In particular,the proposed parameter optimization in the progress of shot peening and effective control of the surface texture provide new rules for the quantitative evaluations of shot peening surface modification of NAK80 steel.MIAO Hong ZUO Dunwen WANG Min ZHANG Ruihong WANG Hongfeng 2011Chinese Journal of Mechanical Engineering2011,24,3:17
8Effects of acid deposition on terrestrial ecosystems and their rehabilitation strategies in China显示文摘South China has become the third largest region associated with acid deposition following Europe and North America, the area subject to damage by acid deposition increased from 1.75 million km 2 in 1985 to 2.8 million km 2 in 1993. Acid deposition has caused serious damage to ecosystem. Combined pollution of acid rain and SO 2 showed the obvious multiple effects on crops. Vegetable was more sensitive to acid deposition than foodstuff crops. Annual economic loss of crops due to acid deposition damage in eleven provinces of south China was 4.26 billion RMB Yuan. Acid deposition caused serious damage to forest. Annual economic loss of wood volume was about 1.8 billion RMB Yuan and forest ecological benefit loss 16.2 billion in eleven provinces of south China. Acid deposition in south China was typical “sulfuric acid type”. According to the thoughts of sustainable development, some strategies were brought forward as follows: (1) enhancing environmental management, specifying acid\|controlling region, controlling and abating the total emission amount of SO 2; (2) selecting practical energy technologies of clean coal, for example, cleansing and selecting coal, sulfur\|fixed\|type industrial briqutting, abating sulfur from waste gas and so on; (3) developing other energy sources to replace coal, including water electricity, atomic energy and the new energy such as solar energy, wind energy and so on; (4) in acid deposition region of south China, selecting acid\|resistant type of crop and tree to decrease agricultural losses, planting more green fertilizer crops, using organic fertilizers and liming, in order to improve buffer capacities of soil.FENG Zong\|wei, MIAO Hong, ZHANG Fu\|zhu, HUANG Yi\|zong (Research Center for Eco\|Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China.

9The Intervention Effect of Rosiglitozone in Ovarian Fibrosis of PCOS Rats显示文摘Objective To explore the Intervention effect of Rosiglitozone in ovarian fibrosis of PCOS rats.Methods 60 female SD rats were randomly divided into 3 groups:control group,model group and treatment group.The model and treatment groups were established by subcutaneous injection of DHEA,while the treatment group was given RGZ.The serum hormone values,pathohistology of ovarian structure of rats,ovarian ultrastructure and the expressions of TGF-β 1 and CTGF were detected.Results The PCOS model was established successfully.The expression intensity of TGF-β 1 and CTGF in Oocytes of the PCOS groups was 9.545±2.954 and 9.665±2.400,respectively and was significantly higher than that of the control group 6.636±2.264 and 7.036±2.133;after treatment with rosiglitazone,the expression was significantly decreased 6.980±2.421 and 6.642±2.721 as compared with that of the model group (P<0.05,P<0.001).The values in serum of the PCOS groups were 3.749±2.054 and 0.265±0.129,and 1.914±1.801 and 0.096±0.088 in the control group which had statistically significant difference (P<0.05,P<0.001).After treatment with rosiglitazone,the values were 2.3100±1.825 and 0.112±0.187 and were significantly different with those of the model group (P<0.05,P<0.001).Conclusion TGF-β 1 and CTGF play an important role in the development of ovary fibrosis in PCOS.However,RGZ may postpone the development of fibrosis by decreasing the levels of TGF-β 1 and CTGF.MIAO Zhu Lin GUO Liang WANG Yong Xia CUI Rong YANG Ning HUANG Mi Qiong QIN Wei Bing CHEN Jin LI Hong Mei WANG Zi Neng WEI Xiang Cai 2012Biomedical and Environmental Sciences2012,25,1:14
10Endoscopic transpancreatic septotomy as a precutting technique for difficult bile duct cannulation显示文摘AIM: To evaluate the technique of transpancreatic septotomy(TS) for cannulating inaccessible common bile ducts in endoscopic retrograde cholangiopancreatography(ERCP).METHODS: Between May 2012 and April 2013, 1074 patients were referred to our department for ERCP. We excluded 15 patients with previous Billroth Ⅱ gastrectomy, Roux-en-Y anastomosis, duodenal stenosis, or duodenal papilla tumor. Among 1059 patients who underwent ERCP, there were 163 patients with difficult bile duct cannulation. Pancreatic guidewire or pancreatic duct plastic stent assistance allowed for successful ERCP completion in 94 patients. We retrospectively analyzed clinical data from 69 failed patients(36 transpancreatic septotomies and 33 needle-knife sphincterotomies). RESULTS: Of the 69 patients who underwent precut papillotomy, common bile duct cannulation was successfully achieved in 67. The success rates in the TS and needle knife sphincterotomy(NKS) groups were 97.2%(35/36) and 96.9%(32/33), respectively, which were not significantly different(P > 0.05). Complications occurred in 11 cases, including acute pancreatitis(n = 6), bleeding(n = 2), and cholangitis(n = 3). The total frequency of complications in the TS group was lower than that in the NKS group(8.3% vs 24.2%, P < 0.05).CONCLUSION: Pancreatic guidewire or pancreatic duct plastic stent assistance improves the success rate of selective bile duct cannulation in ERCP. TS and NKS markedly improve the success rate of selective bile duct cannulation in ERCP. TS precut is safer as compared with NKS.Lin Miao Quan-Peng Li Ming-Hui Zhu Xian-Xiu Ge Hong Yu Fei Wang Guo-Zhong Ji 2015World Journal of Gastroenterology2015,21,13:13

13Hyperinsulinemia,Insulin Resistance and Cognitive Decline in Older Cohort显示文摘Objective Type 2 diabetes has been recently recognized as an important risk factor for cognitive decline of patients with Alzheimer's disease (AD).But the roles of hyperinsulinemia (HI) and insulin resistance (IR) in the development of AD are still controversial.This study was designed to evaluate whether HI or IR influenced the cognitive functions of older cohort.Methods The cognitive functions of 328 consecutive elderly patients were evaluated with a battery of cognitive rating scales.Their fasting blood glucose (FBG) and fasting insulin (FINS) were analyzed and IR was calculated with modified‐Homa.The cognitive scores in different groups and the correlation of cognitive functions with HI or IR were analyzed.Results In our study,there were 180 participants with HI and 148 without HI,and 192 with IR and 136 without IR.The participants with HI showed worse cognitive functions than those without HI in MMSE,MOCA,CDR,orientation,delayed memory,and attention/calculation domains.Similarly,the elderly with IR had lower cognitive scores than those without IR in MMSE,MOCA,CDR,GDS,orientation,delayed memory,and attention/calculation domains.The insulin levels and Homa IR had negative correlation with the scores of MMSE and delayed memory,not only in the model 1 adjusted for FBG and diabetes history,but also in the model 2 adjusted for all nine demographic characteristics.Conclusion HI and IR are important risk factors for cognitive decline of the elderly,especially for the dysfunctions in delayed memory domains.ZHONG Yuan MIAO Ya JIA Wei Ping YAN Hong WANG Bei Yun JIN Jun 2012Biomedical and Environmental Sciences2012,25,1:11
14Covalently closed-circular hepatitis B virus DNA reduction with entecavir or lamivudine显示文摘AIM: To investigate the reduction in hepatitis B virus(HBV) covalently closed-circular DNA(ccc DNA) with entecavir(ETV) or lamivudine(LAM). METHODS: This analysis included patients who had participated in the randomized Phase Ⅲ study ETV-022 comparing ETV vs LAM in nucleos(t)ide-naive, HBe Agpositive patients. Patients received ETV(0.5 mg daily) or LAM(100 mg daily) for a minimum of 52 wk. Patients were eligible to participate in this sub-study if they had paired biopsies at baseline and week 48 with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA. The main objective was to compare changes in hepatic HBV ccc DNA and total hepatic HBV DNA at week 48 of ETV or LAM treatment, which was a secondary endpoint of study ETV-022. Additional post hoc analyses included linear regression analyses to assess associations of baseline levels and on-treatment changes of ccc DNA with other baseline factors [sex,age, serum HBV DNA, alanine aminotransferase(ALT), Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBV genotype], or ontreatment factors(changes from baseline at week 48 in serum HBV DNA, ALT, Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBe Ag loss at week 48).RESULTS: Overall, 305 patients(ETV = 159; LAM = 146) of ETV-022 had paired baseline and week 48 liver biopsies with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA, and were included in this analysis. Baseline demographics and disease characteristics were comparable between the two arms. After 48 wk, ETV resulted in significantly greater reductions in hepatic HBV ccc DNA [-0.9 log10 copies/human genome equivalent(HGEq) vs-0.7 log10 copies/HGEq; P = 0.0033] and total hepatic DNA levels(-2.1 log10 copies/HGEq vs-1.6 log10 copies/HGEq; P < 0.0001) than LAM. Virologic, biochemical, and histologic response rates at week 48 were also greater with ETV than with LAM. Baseline HBV ccc DNA levels were positively associated with baseline levels of serum HBV DNA and total hepatic HBV DNA, and negatively associated with HBV genotype F. On-treatment changes in HBV ccc DNA levels were negatively associated with baseline levels of serum HBV DNA and baseline ALT, and were positively associated with on-treatment changes in the levels of serum HBV DNA, total hepatic HBV DNA levels, and ALT, change in Knodell necroinflammatory score, and HBe Ag loss.CONCLUSION: Forty-eight weeks of ETV resulted in greater reductions in ccc DNA and total hepatic HBV DNA than LAM, but long-term therapy may be needed for ccc DNA elimination.Scott Bowden Stephen Locarnini Ting-Tsung Chang You-Chen Chao Kwang-Hyub Han Robert G Gish Robert A de Man Miao Yu Cyril Llamoso Hong Tang 2015World Journal of Gastroenterology2015,21,15:11

16Essential roles of exosome and circRNA_101093 on ferroptosis desensitization in lung adenocarcinoma显示文摘Background:Resistance to ferroptosis,a regulated cell death caused by irondependent excessive accumulation of lipid peroxides,has recently been linked to lung adenocarcinoma(LUAD).Intracellular antioxidant systems are required for protection against ferroptosis.The purpose of the present studywas to investigate whether and how extracellular system desensitizes LUAD cells to ferroptosis.Methods:Established human lung fibroblasts MRC-5,WI38,and human LUAD H1650,PC9,H1975,H358,A549,and H1299 cell lines,tumor and matched normal adjacent tissues of LUAD,and plasma from healthy individuals and LUAD patients were used in this study.Immunohistochemistry and immunoblotting were used to analyze protein expression,and quantitative reverse transcription-PCR was used to analyze mRNA expression.Cell viability,cell death,and the lipid reactive oxygen species generationwere measured to evaluate the responses to ferroptosis.Exosomes were observed using transmission electron microscope.The localization of arachidonic acid(AA)was detected using click chemistry labeling followed by confocal microscopy.Interactions between RNAs and proteins were detected using RNA pull-down,RNA immunoprecipitation and photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation methods.Proteomic analysis was used to investigate RNA-regulated proteins,and metabolomic analysis was performed to analyze metabolites.Cellderived xenograft,patient-derived xenograft,cell-implanted intrapulmonary LUAD mouse models and plasma/tissue specimens from LUAD patients were used to validate the molecular mechanism.Results:Plasma exosome from LUAD patients specifically reduced lipid peroxidation and desensitized LUAD cells to ferroptosis.A potential explanation is that exosomal circRNA_101093(cir93)maintained an elevation in intracellular cir93 in LUAD to modulate AA,a poly-unsaturated fatty acid critical for ferroptosisassociated increased peroxidation in the plasma membrane.Mechanistically,cir93 interacted with and increased fatty acid-binding protein 3(FABP3),which transported AA and facilitated its reaction with taurine.Thus,global AA was reduced,whereas N-arachidonoyl taurine(NAT,the product of AA and taurine)was induced.Notably,the role of NAT in suppressing AA incorporation into the plasma membrane was also revealed.In pre-clinical in vivo models,reducing exosome improved ferroptosis-based treatment.Conclusion:Exosome and cir93 are essential for desensitizing LUAD cells to ferroptosis,and blocking exosome may be helpful for future LUAD treatment.Xiao Zhang Yunhua Xu Lifang Ma Keke Yu Yongjie Niu Xin Xu Yi Shi Susu Guo Xiangfei Xue Yikun Wang Shiyu Qiu Jiangtao Cui Hong Wang Xiaoting Tian Yayou Miao Fanyu Meng Yongxia Qiao Yongchun Yu Jiayi Wang 2022Cancer Communications2022,42,4:10
