1Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota.Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng 2019Cell Research2019,29,10:192
2Trends in Lipids Level and Dyslipidemia among Chinese Adults, 2002-2015显示文摘Objective To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015.Methods Data were collected from three nationally representative cross-sectional surveys.Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination.Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender.Results The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively;by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period.Similar trends in mean non-HDL-c and lipid-related ratios were observed.The weighted dyslipidemia prevalence linearly increased;in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2%(P for trend <0.001).Conclusion Dyslipidemia increased among Chinese adults from 2002 to 2015.Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.SONG Peng Kun MAN Qing Qing LI Hong PANG Shao Jie JIA Shan Shan LI Yu Qian HE Li ZHAO Wen Hua ZHANG Jian 2019Biomedical and Environmental Sciences2019,32,8:45
3An Investigation of Oxidative DNA Damage in Pharmacy Technicians Exposed to Antineoplastic Drugs in Two Chinese Hospitals Using The Urinary 8-OHdG Assay显示文摘Objective To investigate oxidative DNA damage in pharmacy technicians preparing antineoplastic drugs at the PIVAS (Pharmacy Intravenous Admixture Service) in two Chinese hospitals.Methods Urinary 8-OHdG served as a biomarker.5-Fluorouracil (5-FU) concentrations in air,masks and gloves were determined.The spill exposure of each PIVAS technician to antineoplastic drugs was investigated.Eighty subjects were divided into exposed group I,II,and control group I,II.Results 5-FU concentration ratios for gloves and masks in exposed group I were significantly higher than those in exposed group II (P<0.05 or P<0.01).The average urinary 8-OHdG concentrations in exposed group I,control group I,exposed group II,and control group II were 14.69±0.93,10.68±1.07,10.57±0.55,and 11.96±0.73 ng/mg Cr,respectively.Urinary 8-OHdG concentration in exposed group I was significantly higher than that in control group I or that in exposed group II (P<0.01).There was a significant correlation between urinary 8-OHdG concentrations and spill frequencies per technician (P<0.01).Conclusion There was detectable oxidative DNA damage in PIVAS technicians exposed to antineoplastic drugs.This oxidative DNA damage may be associated with their spill exposure experience and contamination of their personal protective equipment.HUANG Yu Wen JIAN Le ZHANG Mei Bian ZHOU Quan YAN Xiao Feng HUA Xu Dong ZHOU Ying HE Ji Liang 2012Biomedical and Environmental Sciences2012,25,1:30

7BMI, WC, WHtR, VFI and BFI: Which Indictor is the Most Efficient Screening Index on Type 2 Diabetes in Chinese Community Population显示文摘Objective Obesity is a major risk factor for type 2 diabetes, many indexes can be used to describes obesity and predict diabetes. This research attempts to identify the best indicator of obesity to screening diabetes in Chinese population. Methods A cross-sectional data of 8121 subjects aged 35-60 years were included in this research belongs to the Diabetes Appropriate Technology Intervention Study. Anthropometric indicators including body weight, height, waist circumferences (WC), body fat index (BFI) and visceral fat index (VFI) and blood biochemical indicators after an overnight fast [fasting blood glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triacylglycerol] were measured. BMI (body mass index) and Weight to Height Ratio was calculated. Results Subjects with obesity had a higher risk of physician diagnosed diabetes (OR=2.50, 95% CI 1.83-3.43), new diagnosed diabetes (OR=4.23, 95% CI 2.91-6.15) and pre-diabetes (OR=1.75, 95% CI 1.31-2.34) compared to those with normal Body mass index (BMI). There was a significant trend of increased risk of all diabetes status with increased waist circumference (WC). The waist-to-height ratio (WHtR) yielded the most significant association with new diagnosed diabetes and physician diagnosed diabetes than other indices. Conclusion Central obesity is significantly correlated with diabetes. VFI was most correlated with pre-diabetes while WHtR is an efficient screening index than BMI and WC in Chinese community diabetes screening.MI Sheng Quan YIN Peng HU Nan LI Jian Hong CHEN Xiao Rong CHEN Bo YAN Liu Xia ZHAO Wen Hua 2013Biomedical and Environmental Sciences2013,26,6:20

9Constructed wetlands for wastewater treatment in cold climate--A review显示文摘Constructed wetlands(CWs) have been successfully used for treating various wastewaters for decades and have been identified as a sustainable wastewater management option worldwide.However,the application of CW for wastewater treatment in frigid climate presents special challenges.Wetland treatment of wastewater relies largely on biological processes,and reliable treatment is often a function of climate conditions.To date,the rate of adoption of wetland technology for wastewater treatment in cold regions has been slow and there are relatively few published reports on CW applications in cold climate.This paper therefore highlights the practice and applications of treatment wetlands in cold climate.A comprehensive review of the effectiveness of contaminant removal in different wetland systems including:(1) free water surface(FWS) CWs;(2) subsurface flow(SSF) CWs;and(3) hybrid wetland systems,is presented.The emphasis of this review is also placed on the influence of cold weather conditions on the removal efficacies of different contaminants.The strategies of wetland design and operation for performance intensification,such as the presence of plant,operational mode,effluent recirculation,artificial aeration and in-series design,which are crucial to achieve the sustainable treatment performance in cold climate,are also discussed.This study is conducive to further research for the understanding of CW design and treatment performance in cold climate.Mo Wang Dong Qing Zhang Jian Wen Dong Soon Keat Tan 2017Journal of Environmental Sciences2017,29,7:19
10Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang 2014Biomedical and Environmental Sciences2014,27,5:17

12Fine mapping and marker-assisted selection (MAS) of a low glutelin content gene in rice显示文摘Rice with low glutelin content is suitable as functional food for patients affected with diabetes and kidney failure. The fine mapping of the gene(s) responsible for low glutelin content will provide information regarding the distribution of glutelin related genes in rice genome and will generate markers for the selection of low glutelin rice varieties. Following an SDS-PAGE screen of rice germplasm from Taihu Valley of China, Japonica selection W3660 is identified to be a novel mutant characterized with low glutelin content. For fine mapping the mutant gene for low glutelin content, F2 and F3 populations were derived from a cross between W3660 and Jingrennuo. SDS-PAGE analysis of the total endosperm protein showed that the low glutelin content trait was controlled by a single dominant nuclear gene. Genetic mapping, using SSRs, located this gene to chromosome 2, in the region between SSR2-001/SSR2-004 and RM1358. The dis- tances of the two markers to the target gene were 1.1 cM and 3.8 cM respectively. By semi-quantitative RT-PCR analysis, the transcripts of GluB4/GluB5 genes located within the region do not change. However, GluB5 gene located proximal to SSR2-001/SSR2-004 was specifically reduced. SSR profiles of seven Japonica varieties were compared with that of W3660 for loci in the relevant genetic region. The markers SSR2-004 and RM1358 were used for marker- assisted selection. The selection efficiencies of SSR2-004 and RM1358 were 96.8% and 92.7% respectively. This provides a standard starting point for the breeding of low glutelin content rice varieties in China.Yi Hua WANG Shi Jia LIU Su Lan JI Wen Wei ZHANG Chun Ming WANG Ling JIANG Jian Min WAN 2005Cell Research2005,15,8:16

15A New RFID Anti-collision Algorithm Based on the Q-Ary Search Scheme显示文摘Deterministic tree-based algorithms are mostly used to guarantee that all the tags in the reader field are successfully identified, and to achieve the best performance. Through an analysis of the deficiencies of existing tree-based algorithms, a Q-ary search algorithm was proposed. The Q-ary search(QAS) algorithm introduced a bit encoding mechanism of tag ID by which the multibit collision arbitration was implemented. According to the encoding mechanism, the collision cycle was reduced. The theoretical analysis and simulation results showed that the proposed MS algorithm overcame the shortcoming of existing tree-based algorithms and exhibited good performance during identification.SU Jian WEN Guangjun HONG Danfeng 2015Chinese Journal of Electronics2015,24,4:13
16Evaluation and prediction of ecological suitability of medicinal plant American ginseng (panax quinquefolius)显示文摘Objective: American ginseng is a medicinal plant with large market demands,however,its producing areas are shrinking because of the continuous cropping obstacles in China.Therefore,it is urgent to establish a suitable model to determine the new producing areas.Here we evaluated and predicted the suitable areas of American ginseng using the maximum entropy model(Max Ent).Methods: Based on the 37 environmental variables over thirty years from 1970 to 20 0 0 and 226 global distribution points of American ginseng,Max Ent was used to determine the global ecological suitable areas for American ginseng.The Receiver Operating Curve(ROC)was used to evaluate the model prediction accuracy.Meanwhile,an innovative ecological variable,the precipitation–temperature ratio,was established to indicate the climate characteristic in the American ginseng suitable areas based on the monthly precipitation and temperature.Results: The potential ecological suitable areas of American ginseng were primarily in Appalachian Mountain in America and Changbai Mountain in China,about in the range of 35 °N–50 °N,60 °W–120 °W and 35 °N–50 °N,110 °E–145 °E,respectively,including the United States,Canada,China,North Korea,South Korea,Russia and Japan.South Korea and Japan were the potential producing regions.The precipitation–temperature ratios were stable at(0.22,0.56)of the vigorous growth period(April–October)in the best suitable areas of American ginseng,serving as characteristic parameters to optimize the prediction model.The model showed that the common soil parameters were pH 4.5–7.2,Base Saturation(BS)above 80%,Cation Exchange Capacity(CEC)10–20 cmol/kg,organic carbon(OC)< 1.4%,and the soil types were sandy loam or loam.Conclusion: An optimized Max Ent model was established to predict the producing area for American ginseng that needed to be validated by a field test.Qin Zhang Jian Wen Zi-Qian Chang Cai-Xiang Xie Jing-Yuan Song 2018Chinese Herbal Medicines2018,10,1:12
173-D shear wave velocity structure in the shallow crust of the Tan-Lu fault zone in Lujiang,Anhui,and adjacent areas,and its tectonic implications显示文摘The Tan-Lu fault zone is a large NNE-trending fault zone in eastern China.Investigations of the structures of the fault zone and its surrounding areas have attracted much attention.In this study,we used dense-array ambient noise tomography to construct a threedimensional shear wave velocity model of shallow crust in an area about 80km×70km in Lujiang,Anhui Province,eastern China.For approximately one month we collected continuous ambient noise signals recorded by 90 short-period seismographs in the region,and obtained the short-period Rayleigh wave empirical Green's functions between stations by the cross-correlation method;we also extracted 0.5–8 s fundamental mode Rayleigh wave group velocity and phase velocity dispersion curves.Based on the direct surface wave tomography method,we jointly inverted the group velocity and phase velocity dispersion data of all paths and obtained the 3-D shear wave velocity structure in the depth range of 0–5 km.The results revealed important geological structural features of the study area.In the north region,the sedimentary center of the Hefei Basin—the southwestern part of the Chaohu Lake—shows a significant low-velocity anomaly to a depth of at least 5 km.The southwestern and southeastern regions of the array are the eastern margin of the Dabie orogenic belt and the intrusion area of Luzong volcanic rocks,respectively,and both show obvious high-speed anomalies;the sedimentary area within the Tan-Lu fault zone(about 10 km wide)shows low-velocity anomalies.However,the volcanic rock intrusion area in the fault zone is shown as high velocity.Our shallow crustal imaging results reflect the characteristics of different structures in the study area,especially the high-speed intrusive rocks in the Tan-Lu fault zone,which were probably partially derived from the magmatic activity of Luzong volcanic basin.From the Late Cretaceous to Early Tertiary,the Tan-Lu fault zone was in a period of extensional activity;the special stress environment and the fractured fault zone morphology provided conditions for magma in the Luzong volcanic basin to intrude into the Tan-Lu fault zone in the west.Our 3-D model can also provide important information for deep resource exploration and earthquake strong ground motion simulation.Cheng Li HuaJian Yao Yuan Yang Song Luo KangDong Wang KeSong Wan Jian Wen Bin Liu 2020Earth and Planetary Physics2020,4,3:12
18Minimizing tacrolimus decreases the risk of new-onset diabetes mellitus after liver transplantation显示文摘AbstractAIM: To investigate the impact of minimum tacrolimus(TAC) on new-onset diabetes mellitus (NODM) afterliver transplantation (LT).METHODS: We retrospectively analyzed the data of973 liver transplant recipients between March 1999and September 2014 in West China Hospital LiverTransplantation Center. Following the exclusion ofineligible recipients, 528 recipients with a TAC-dominantregimen were included in our study. We calculatedand determined the mean trough concentration ofTAC (cTAC) in the year of diabetes diagnosis in NODMrecipients or in the last year of the follow-up in non-NODM recipients. A cutoff of mean cTAC value forpredicting NODM 6 mo after LT was identified usinga receptor operating characteristic curve. TAC-relatedcomplications after LT was evaluated by χ^2 test, andthe overall and allograft survival was evaluated usingthe Kaplan-Meier method. Risk factors for NODM afterLT were examined by univariate and multivariate Cox regression.RESULTS: Of the 528 transplant recipients, 131(24.8%) developed NODM after 6 mo after LT, andthe cumulative incidence of NODM progressivelyincreased. The mean cTAC of NODM group recipientswas significantly higher than that of recipients in thenon-NODM group (7.66 ± 3.41 ng/mL vs 4.47 ± 2.22ng/mL, P 〈 0.05). Furthermore, NODM group recipientshad lower 1-, 5-, 10-year overall survival rates (86.7%,71.3%, and 61.1% vs 94.7%, 86.1%, and 83.7%, P 〈0.05) and allograft survival rates (92.8%, 84.6%, and75.7% vs 96.1%, 91%, and 86.1%, P 〈 0.05) thanthe others. The best cutoff of mean cTAC for predictingNODM was 5.89 ng/mL after 6 mo after LT. Multivariateanalysis showed that old age at the time of LT (〉 50years), hypertension pre-LT, and high mean cTAC (≥5.89 ng/mL) after 6 mo after LT were independent riskfactors for developing NODM. Concurrently, recipientswith a low cTAC (〈 5.89 ng/mL) were less likely tobecome obese (21.3% vs 30.2%, P 〈 0.05) or todevelop dyslipidemia (27.5% vs 44.8%, P 〈0.05),chronic kidney dysfunction (14.6% vs 22.7%, P 〈 0.05),and moderate to severe infection (24.7% vs 33.1%, P〈 0.05) after LT than recipients in the high mean cTACgroup. However, the two groups showed no significantdifference in the incidence of acute and chronicrejection, hypertension, cardiovascular events and newonsetmalignancy.CONCLUSION: A minimal TAC regimen can decreasethe risk of long-term NODM after LT. Maintaining a cTACvalue below 5.89 ng/mL after LT is safe and beneficial.Jiu-Lin Song Wei Gao Yan Zhong Lu-Nan Yan Jia-Yin Yang Tian-Fu Wen Bo Li Wen-Tao Wang Hong Wu Ming-Qing Xu Zhe-Yu Chen Yong-Gang Wei Li Jiang Jian Yang 2016World Journal of Gastroenterology2016,22,6:12
