1慢性肾脏病中的炎症和动脉硬化:慢性肾功能不全队列研究中的发现显示文摘慢性肾脏病(chronic kidney disease,CKD)和动脉硬化程度与心血管病发病率和死亡率增加相关。目前认为炎症在动脉硬化发展中发挥作用,而CKD被认为是一种促炎症反应的状态。CKD患者的动脉僵硬度增加,横断面数据提示CKD中增多的炎症标志物与较高动脉僵硬度值相关。Peyster E Chen J Feldman HI Go AS Gupta J Mitra N Pan Q Porter A Rahman M Raj D Reilly M Wing MR Yang W Townsend RR 陈云 叶鹏 2017中华高血压杂志2017,25,11:12
2Efficacy and safety of tenofovir in chronic hepatitis B: Australian real world experience显示文摘AIM To evaluate the long-term treatment outcomes of tenofovir therapy in patients in a real world Australian tertiary care setting.METHODS We performed a retrospective analysis of treatment outcomes among treatment-na?ve and treatment-experienced patients receiving a minimum 3 mo tenofovir therapy through St Vincent's Hospital Melbourne, Australia. We included patients receiving tenofovir [tenofovir disoproxil fumarate(TDF)] monotherapy, as well as patients treated with TDF in combination with a second antiviral agent. Patients were excluded if they demonstrated human immune-deficiency virus/hepatitis C virus/hepatitis delta virus coinfection or were less than 18 years of age. We considered virological and biochemicalresponse, as well as safety outcomes. Virological response was determined by measurement of hepatitis B virus(HBV) DNA using sensitive assays; biochemical response was determined via serum liver function tests; histological response was determined from liver biopsy and fibroscan; safety analysis focused on glomerular renal function and bone mineral density. The primary efficacy endpoint was complete virological suppression over time, defined by HBV DNA < 20 IU/m L. Secondary efficacy endpoints included rates of biochemical response, and HB e antigen(HBe Ag)/HB surface antigen loss and seroconversion over time.RESULTS Ninety-two patients were identified who fulfilled the enrolment criteria. Median follow-up was 26 mo(range 3-114). Mean age was 46(24-78) years, 64(70%) were male and 77(84%) were of Asian origin. 55(60%) patients were treatment-na?ve and 62 patients(67%) were HBe Ag-negative. Complete virological suppression was achieved by 45/65(71%) patients at 12 mo, 37/46(80%) at 24 mo and 25/28(89%) at 36 mo. Partial virological response(HBV DNA 20-2000 IU/m L) was achieved by 89/92(96.7%) of patients. Multivariate analysis showed a significant relationship between virological suppression at end of follow-up and baseline HBV DNA level(OR = 0.897, 95%CI: 0.833-0.967, P = 0.0046) and HBe Ag positive status(OR = 0.373, 95%CI: 0.183-0.762, P = 0.0069). There was no difference in response comparing treatment-na?ve and treatment-experienced patients. Three episodes of virological breakthrough occurred in the setting of noncompliance. Tenofovir therapy was well tolerated.CONCLUSION Tenofovir is an efficacious, safe and well-tolerated treatment in an Australian real-world tertiary care setting. Our data are similar to the reported experience from registration trials.Grace C Lovett Tin Nguyen David M Iser Jacinta A Holmes Robert Chen Barbara Demediuk Gideon Shaw Sally J Bell Paul V Desmond Alexander J Thompson 2017World Journal of Hepatology2017,9,1:7

4Source identification, contamination status and health risk assessment of heavy metals from road dusts in Dhaka, Bangladesh显示文摘In this study, concentrations of Cr, Mn, Ni, Cu, Zn, Cd and Pb were determined in road dusts collected from different locations in Dhaka to assess source, contamination status and health risk. Energy-dispersive X-ray fluorescence spectroscopy and energy-dispersive X-ray spectroscopy were used to determine Cr, Mn, Ni, Cu, Zn, Cd and Pb and their mean concentrations were 162.27 ± 29.46, 721.18 ± 180.14, 35.65 ± 12.55, 104.56 ± 128.33, 515.32 ± 321.90,BDL, and 342.82 ± 591.20 mg/kg, respectively. Among the heavy metals, highest concentrations of Cu, Zn and Pb were found at urban sites-7(municipal waste dumping) and 8(medical waste incineration). Highest concentration of Cr followed by Cu and Zn was found at site-5(Tejgaon, urban). Principal component analysis revealed that anthropogenic activities are the potential sources for Cr, Ni, Cu, Zn and Pb while earth crust for Mn. Pollution index and pollution load index results suggested that all the sites were contaminated and/or degraded by Cr, Cu, Zn and Pb except sites-9(urban), 10(sub-urban), 11(rural) while sites-7 and 8(urban) were extremely degraded. For noncarcinogenic health risk, hazard quotient values for dermal were higher compared to that of inhalation/ingestion. Though hazard index values were less than 1 at all the sites, these were at least one order of magnitude higher for children group than that of adult group, thus the children group may face more noncarcinogenic health risk at sites -7 and 8. Values of incremental lifetime cancer risk were from 10to 10showed no carcinogenic health risk by road dusts contaminated with the heavy metals.Aklima Nargis Ahsan Habib Md Nazrul Islam Kai Chen Md Shafiqul Islam Sarker A N M Al-Razee Wenbin Liu Guorui Liu Minggang Cai 2022Journal of Environmental Sciences2022,34,11:3
5Modeling contaminant transport in homogeneous porous media with fractional advection-dispersion equation显示文摘The newly developed Fractional Advection-Dispersion Equation (FADE), which is FADE was extended and used in this paper for modelling adsorbing contaminant transport by adding an adsorbing term. A parameter estimation method and its corresponding FORTRAN based program named FADEMain were developed on the basis of Nonlinear Least Square Algorithm and the analytical solution for one-dimensional FADE under the conditions of step input and steady state flow. Data sets of adsorbing contaminants Cd and NH4+-N transport in short homogeneous soil columns and conservative solute NaCI transport in a long homogeneous soil column, respectively were used to estimate the transport parameters both by FADEMain and the advection-dispersion equation (ADE) based program CXTFIT2.1. Results indicated that the concentration simulated by FADE agreed well with the measured data. Compared to the ADE model, FADE can provide better simulation for the concentration in the initial lower concentration part and the late higher concentration part of the breakthrough curves for both adsorbing contaminants. The dispersion coefficients for ADE were from 0.13 to 7.06 cm2/min, while the dispersion coefficients for FADE ranged from 0.119 to 3.05 cm1.856/min for NaCI transport in the long homogeneous soil column. We found that the dispersion coefficient of FADE increased with the transport distance, and the relationship between them can be quantified with an exponential function. Less scale-dependent was also found for the dispersion coefficient of FADE with respect to ADE.HUANG Guanhua, HUANG Quanzhong, ZHAN Hongbin , CHEN Jing, XIONG Yunwu & FENG Shaoyuan College of Hydraulic and Civil Engineering, China Agricultural University, Beijing 100083, China Chinese-Israeli International Center for Research and Training in Agriculture, Beijing 100083, China Department of Geology and Geophysics, Texas A& M University, TZ77843-3115, USA 2005Science China Earth Sciences2005,48,z2:3
6Discrete large eddy simulation显示文摘Despite the intense effort expended towards obtaining a model for describing the turbulent flows of fluid, there is no model at hand that can do an adequate job. This leads us to look for a non-traditional approach to turbulence modeling. In this work we conjoin the notion of large eddy simulation with those of fuzzy sets and neural networks to describe a class of turbulent flows. In previous works we had discussed several issues concerning large eddy simulation such as filtering and averaging. Here, we discuss the use of fuzzy sets to improve the filtering procedure.L.

8Prediction of mortality among patients with chronic kidney disease:A systematic review显示文摘BACKGROUND Chronic kidney disease(CKD)is a common medical condition that is increasing in prevalence.Existing published evidence has revealed through regression analyses that several clinical characteristics are associated with mortality in CKD patients.However,the predictive accuracies of these risk factors for mortality have not been clearly demonstrated.AIM To demonstrate the accuracy of mortality predictive factors in CKD patients by utilizing the area under the receiver operating characteristic(ROC)curve(AUC)analysis.METHODS We searched Ovid MEDLINE,EMBASE,and the Cochrane Library for eligible articles through January 2021.Studies were included based on the following criteria:(1)Study nature was observational or conference abstract;(2)Study populations involved patients with non-transplant CKD at any CKD stage severity;and(3)Predictive factors for mortality were presented with AUC analysis and its associated 95%confidence interval(CI).AUC of 0.70-0.79 is considered acceptable,0.80-0.89 is considered excellent,and more than 0.90 is considered outstanding.RESULTS Of 1759 citations,a total of 18 studies(n=14579)were included in this systematic review.Eight hundred thirty two patients had non-dialysis CKD,and 13747 patients had dialysis-dependent CKD(2160 patients on hemodialysis,370 patients on peritoneal dialysis,and 11217 patients on non-differentiated dialysis modality).Of 24 mortality predictive factors,none were deemed outstanding for mortality prediction.A total of seven predictive factors[N-terminal pro-brain natriuretic peptide(NT-proBNP),BNP,soluble urokinase plasminogen activator receptor(suPAR),augmentation index,left atrial reservoir strain,C-reactive protein,and systolic pulmonary artery pressure]were identified as excellent.Seventeen predictive factors were in the acceptable range,which we classified into the following subgroups:predictors for the non-dialysis population,echocardiographic factors,comorbidities,and miscellaneous.CONCLUSION Several factors were found to predict mortality in CKD patients.Echocardiography is an important tool for mortality prognostication in CKD patients by evaluating left atrial reservoir strain,systolic pulmonary artery pressure,diastolic function,and left ventricular mass index.Panupong Hansrivijit Yi-Ju Chen Kriti Lnu Angkawipa Trongtorsak Max M Puthenpura Charat Thongprayoon Tarun Bathini Michael A Mao Wisit Cheungpasitporn 2021World Journal of Nephrology2021,10,4:2
