| 1 | Blood Pressure Associated with Arsenic Methylation and Arsenic Metabolism Caused by Chronic Exposure to Arsenic in Tube Well Water显示文摘Objective The effects of arsenic exposure from drinking water, arsenic metabolism, and arsenic methylation on blood pressure(BP) were observed in this study. Methods The BP and arsenic species of 560 participants were determined. Logistic regression analysis was applied to estimate the odds ratios of BP associated with arsenic metabolites and arsenic methylation capability. Results BP was positively associated with cumulative arsenic exposure(CAE). Subjects with abnormal diastolic blood pressure(DBP), systolic blood pressure(SBP), and pulse pressure(PP) usually had higher urinary i As(inorganic arsenic), MMA(monomethylated arsenic), DMA(dimethylated arsenic), and TAs(total arsenic) than subjects with normal DBP, SBP, and PP. The i As%, MMA%, and DMA% differed slightly between subjects with abnormal BP and those with normal BP. The PMI and SMI were slightly higher in subjects with abnormal PP than in those with normal PP. Conclusion Our findings suggest that higher CAE may elevate BP. Males may have a higher risk of abnormal DBP, whereas females have a higher risk of abnormal SBP and PP. Higher urinary i As may increase the risk of abnormal BP. Lower PMI may elevate the BP. However, higher SMI may increase the DBP and SBP, and lower SMI may elevate the PP. | WEI Bing Gan YE Bi Xiong YU Jiang Ping YANG Lin Sheng LI Hai Rong XIA Ya Juan WU Ke Gong | 2017 | Biomedical and Environmental Sciences2017，30，5： | 9 |
| 2 | Induction of Endoplasmic Reticulum Stress by Cadmium and Its Regulation on Nrf2 Signaling Pathway in Kidneys of Rats显示文摘Objective This study was conducted to investigate the regulation of endoplasmic reticulum stress on Nrf2 signaling pathway in the kidneys of rats. Methods Rats were divided into twelve groups of six animals each. Some groups were pre-administered with bacitracin or tauroursodeoxycholic acid(TUDCA), and all of them were treated with 5-20 μmol/kg cadmium(Cd) for 48 h. The oxidative stress levels were analyzed using kits. The mRNA and protein expression levels of endoplasmic reticulum stress-related factors and Nrf2 signaling pathway-related factors were determined using RT-PCR and western blot. Results Cd exposure resulted in oxidative stress in the kidneys of rats and upregulated the expression of endoplasmic reticulum stress(ERS)-related factors and Nrf2 signaling pathway-related factors, especially at doses of 10 and 20 μmol/kg Cd, and the expression changes were particularly obvious. Moreover, after pretreatment with bacitracin, Cd upregulated the expression of ERS-related factors to a certain extent and, at higher doses, increased the mRNA expression of Nrf2. After pretreatment with TUDCA, Cd reduced the level of ERS to a certain extent; however, at these doses, there were no significant changes in the expression of Nrf2. Conclusion Cadmium can result in ERS and oxidative stress in the kidneys of rats, activate Nrf2, and upregulate the transcriptional expression of phase II detoxification enzymes under these experimental conditions. ERS has a positive regulation effect on Nrf2 signaling pathway but has little effect on the negative regulation of Nrf2 signaling pathway in cadmium toxicity. | CHEN Zhi Jian CHEN Jia Xing WU Li Kang LI Bi Yun TIAN Ya Feng XIAN Min HUANG Zi Pei YU Ri An | 2019 | Biomedical and Environmental Sciences2019，32，1： | 6 |
| 3 | Detailed resume of RNA m^(6)A demethylases显示文摘N6-Methyladenosine(m^(6)A) is the most abundant internal modification in eukaryotic mRNA,playing critical role in various bioprocesses. Like other epigenetic modifications, m^(6)A modification can be catalyzed by the methyltransferase complex and erased dynamically to maintain cells homeostasis. Up to now, only two m^(6)A demethylases have been reported, fat mass and obesity-associated protein(FTO)and alkylation protein AlkB homolog 5(ALKBH5), involving in a wide range of mRNA biological progress, including mRNA shearing, export, metabolism and stability. Furthermore, they participate in many significantly biological signaling pathway, and contribute to the progress and development of cancer along with other diseases. In this review, we focus on the studies about structure, inhibitors development and biological function of FTO and ALKBH5. | Dandan Shen Bo Wang Ya Gao Lijuan Zhao Yaping Bi Jinge Zhang Ning Wang Huiqin Kang Jingru Pang Ying Liu Luping Pang Zhe-Sheng Chen Yi-Chao Zheng Hong-Min Liu | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 3 |
| 4 | Association between Coronary Atherosclerotic Plaque Composition and Cardiovascular Disease Risk显示文摘Objective The objective of this study is to determine whether coronary atherosclerotic plaque composition is associated with cardiovascular disease(CVD) risk in Chinese adults. Methods We performed a cross-sectional analysis in 549 subjects without previous diagnosis or clinical symptoms of CVD in a community cohort of middle-aged Chinese adults. The participants underwent coronary computed tomography(CT) angiography for the evaluation of the presence and composition of coronary plaques. CVD risk was evaluated by the Framingham risk score(FRS) and the 10-year atherosclerotic cardiovascular disease(ASCVD) risk score. Results Among the 549 participants, 267(48.6%) had no coronary plaques, 201(36.6%) had noncalcified coronary plaques, and 81(14.8%) had calcified or mixed coronary plaques. The measures of CVD risk including FRS and ASCVD risk score and the likelihood of having elevated FRS significantly increased across the groups of participants without coronary plaques, with noncalcified coronary plaques, and with calcified or mixed coronary plaques. However, only calcified or mixed coronary plaques were significantly associated with an elevated ASCVD risk score [odds ratio(OR) 2.41; 95% confidence interval(CI) 1.09-5.32] compared with no coronary plaques, whereas no significant association was found for noncalcified coronary plaques and elevated ASCVD risk score(OR 1.25; 95% CI 0.71-2.21) after multivariable adjustment. Conclusion Calcified or mixed coronary plaques might be more associated with an elevated likelihood of having CVD than noncalcified coronary plaques. | LI Lin WANG Long LIU Shan Shan ZHAO Zhi Yun LI Mian WANG Tian Ge XU Min LU Jie Li CHEN Yu Hong WANG Shuang Yuan DAI Meng HOU Ya Nan WU Xue Yan MA Li Na WANG Wei Qing XU Yu BI Yu Fang | 2019 | Biomedical and Environmental Sciences2019，32，2： | 3 |
| 5 | Inverted 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 | 2021 | Biomedical and Environmental Sciences2021，34，1： | 2 |

| 9 | A deeper exploration of the relation between sulfonation degree and retanning performance of aromatic syntans显示文摘It is well‑known that the sulfonation degree(DS)of aromatic syntan is an important factor affecting its retanning performances.But the quantitative relation between DS and syntan property and the influencing mechanism of DS on syntan property are not clarified.In this work,five phenolic formaldehyde syntans(PFSs)with the same polym‑erization degree but varying DS were prepared to investigate the effect of DS on the properties of syntan and crust leather.It was found that the absolute value of zeta potential and the particle size of PFS decreased with increasing DS in aqueous solution.Molecular dynamic simulation results proved that the DS of PFS was a major contributor to electrostatic interaction and hydrogen bonding in the PFS–water system and greatly affected the aggregation and dispersion of PFS in aqueous solution.The PFS with a low DS was prone to aggregate to large particles in aqueous solution because of low intermolecular electrostatic repulsion and less hydrogen bonds and therefore can be used to increase the thickness and tightness of leather.The PFS with a high DS presented a small particle size with more anionic groups in aqueous solution,thereby sharply decreasing the positive charge of leather surface and facilitat‑ing the penetration of the post‑tanning agents into the leather.These results might be scientifically valid for rational molecular design of syntans and more productive use of syntans in leather making. | Qingyong Sun Yunhang Zeng Ya‑nan Wang Yue Yu Bi Shi | 2021 | Journal of Leather Science and Engineering2021，3，1： | 1 |

| 11 | Cellular Fatty Acids as Chemical Markers for Differentiation of Acinetobacter baumannii and Acinetobacter calcoaceticus显示文摘Objective Gas chromatography (GC) was used to investigate the cellular fatty acid (CFA) composition of 141 Acinetobacter baumannii and 32 A. calcoaceticus isolates from different locations in China and to find chemical markers to differentiate these two closely related bacteria. Methods Whole cell fatty acid methyl esters (FAMEs) were obtained by saponification, methylation, and extraction for GC analysis, followed by a standardized Microbial Identification System (MIS) analysis. Results All A. baumannii and A. calcoaceticus strains contained some major fatty acids, namely, 18:1 ω9c, 16:0, Sum In Feature 3, 12:0, 17:1ω8c, 3-OH-12:0, 17:0, Sum In Feature 2, 2-OH-12:0, and 18:0 compounds. Although most of the total CFAs are similar between A. baumannii and A. calcoaceticus strains, the ratios of two pairs of CFAs, i.e., Sum In Feature 3/18:1 ω9c versus 16:0/18:1 ω9c and Sum In Feature 3/18:1 ω9c versus unknown 12.484/18:1 ω9c fatty acids, could differentiate these two closely related bacteria. A. baumannii could be easily classified into two subgroups by plotting some ratios such as Sum In Feature 3/16:0 versus 17:0 and Sum In Feature 3/2-OH-12:0 versus17:0 fatty acids. Conclusion The ratios of some CFAs could be used as chemical markers to distinguish A. baumannii from A. calcoaceticus. | YANG Chao GUO Zhao Biao DU Zong Min YANG Hui Ying BI Yu Jing WANG Gui Qin TAN Ya Fang | 2012 | Biomedical and Environmental Sciences2012，25，6： | 1 |
| 12 | Ideal Cardiovascular Health is Inversely Associated with Subclinical Atherosclerosis: A Prospective Analysis显示文摘Objective Ideal cardiovascular health(CVH) could predict a lower risk of developing cardiovascular diseases. This study was conducted to investigate the association between ideal CVH and subclinical atherosclerosis in a population cohort of Chinese adults aged ≥ 40 years. Methods This study was designed as a cross-sectional analysis of 8,395 participants who had complete data at baseline and a prospective analysis of 4,879 participants who had complete data at 4.3 years of follow-up. Ideal CVH metrics were defined according to the American Heart Association. Subclinical atherosclerosis was evaluated by plaques in carotid arteries, carotid intima-media thickness(CIMT), brachial-ankle pulse wave velocity(baPWV), and urinary albumin-to-creatinine ratio(UACR). Results Both the prevalence and incidence of atherosclerosis measures were found to be decreased with increasing numbers of ideal CVH metrics at baseline(all P values for trend < 0.01). The levels of CIMT and UACR at follow-up showed an inverse and significant association with the numbers of ideal CVH metrics at baseline(both P values for trend < 0.05) but a borderline significant association with baPWV(P for trend = 0.0505). Taking participants with 0-1 ideal metric as reference, we found that participants with 5-6 ideal metrics had significantly lower risks of developing carotid plaques(odds ratio, OR = 0.46; 95% confidence interval, CI 0.27-0.79), increased CIMT(OR = 0.60; 95% CI 0.42-0.84), and increased baPWV(OR = 0.57; 95% CI 0.34-0.97) after full adjustments. A significant interactive effect of age and CVH was detected on CIMT and baPWV progression(both P values for interaction < 0.05). Conclusion The numbers of ideal CVH metrics showed a significant and inverse association with the risk of developing subclinical atherosclerosis in middle-aged and elderly Chinese adults, whereas its dose-response effect was attenuated in individuals aged ≥ 60 years and partially weakened in male participants. | WANG Long NIU Jing Ya ZHAO Zhi Yun LI Mian XU Min LU Jie Li WANG Tian Ge CHEN Yu Hong WANG Shuang Yuan DAI Meng LI Lin LIU Shan Shan WANG Wei Qing XU Yu BI Yu Fang | 2019 | Biomedical and Environmental Sciences2019，32，4： | 1 |

| 19 | FMR1NB Involved in Glioma Tumorigenesis Is a Promising Target for Prognosis and Therapy显示文摘Objective:Cancer/testis antigen FMR1NB is aberrantly expressed in various types of cancer,but not in normal tissues except for testis.This study aimed to investigate the expression and functional role of FMR1NB in glioma.Methods:The expression of FMR1NB mRNA and protein was determined using RT-PCR and immunohistochemistry,respectively,in glioma specimens from 83 patients at follow-up.The effects of siRNA-mediated FMR1NB silencing on malignant biological behaviors were evaluated in glioma cell lines Al 72 and U251.Results:FMR1NB mRNA and protein expression was detected in 58.8%(77/131)and 46.34%(57/123)of glioma tissues,respectively.FMR1NB protein was positively correlated with World Health Organization grade and found to be an independent prognostic marker for poor outcome.Knockdown of FMR1NB induced apoptosis and suppressed proliferation,adhesion,migration,and invasion by modulating the expression of cyclin A,CDK2,caspase-3,E-cadherin,and N-cadherin in A172 and U251 cells.Conclusion:Our findings suggest that FMR1NB contributes to the tumorigenesis of glioma cells and may represent a potential prognostic biomarker and an attractive therapeutic target in glioma. | Shui-qing BI Ya PENG Zong-dang WEI Sheng-zhong YAO Bin LUO Ying-ying GE Xiao-xun XIE Wei-xia NONG Chang LIU Shao-wen XIAO Qing-mei ZHANG | 2022 | Current Medical Science2022，42，4： | 0 |
| 20 | Simulation of a soft-gamma-ray polarimeter on board a microsatellite显示文摘Gamma-ray polarimetry is a new and prospective tool for studying extremely high-energy celestial objects and is of great significance for the field of astrophysics.With the rapid development of microsatellite technology,the advantages of space exploration have become increasingly apparent.Therefore,we simulated a soft-gamma-ray polarimeter for a microsatellite based on the Compton scattering principle.We performed detailed Monte Carlo simulations using monoenergetic gamma-ray linear-polarization sources and Crab-like sources in the energy range of 0.1-10 MeV considering the orbital background.The polarimeter exhibited excellent polarization detection performance.The modulation factor was 0.80±0.01,and the polarization angles were accurate within an error of 0.2°at 200 keV for on-axis incidence.For the Crab-like sources for on-axis incidence,the polarization degrees were consistent with the set values within the error tolerance,the modulation factor was 0.76±0.01,and the minimum detectable polarization reached 2.4%at 3σfor an observation time of10^(6) s.Additionally,the polarimeter exhibited recoil electron tracking,imaging,and powerful background suppression in a large field of view(FoV;∼2πsr).The proposed polarimeter meets the requirements of a space soft-gamma-ray polarization detector and has promising research prospects. | Xiang‑Man Liu Shu‑Wen Tang Wei Wang Yu‑Hong Yu Zhi‑Yu Sun Yong‑Jie Zhang Fang Fang Duo Yan Shi‑Tao Wang Xue‑Heng Zhang Shu‑Ya Jin Bi‑Tao Hu | 2023 | Nuclear Science and Techniques2023，34，11： | 0 |
