The urinary N-acetyl-13-D-glucosaminidase （UNAG） was chosen as an effect biomarker. The UCd BMDLs for UNAG ranged from 2.18μg/g creatinine （cr） to 4.26μg/g cr in the populations of different provinces. The selection of the sample population and area affect the evaluation of the BMDL. The reference level of UCd for renal effects was further evaluated based on the data of all 6103 subjects. With benchmark responses （BMR） of 10%/5%, the overall UCd BMDLs for males in the total population were 3.73/2.08 μg/g cr. The BMD was slightly lower in females, thereby indicating that females may be relatively more sensitive to Cd exposure than are males.展开更多

The results suggest that GFR and ERPF are sensitive and efficient renal function indicators in monitoring the change of the disease and assessing therapeutic effect.

In the control group, patients were given routine care: informing the precautions before and after operation, observing the changes of vital signs and bleeding after operation, etc. In the observation group, patients were given bundle care intervention, including preoperative, intraoperative and postoperative routine care, ankle pump exercise, Intermittent Pneumatic Compression (IPC) treatment and psychological care. The incidence of lower-limb venous thrombosis was compared between the two groups. <strong>Results:</strong> The incidence of deep venous thrombosis in the observation group was lower than that in the control group (P < 0.05), 1 case (0.6%) in the observation group and 8 cases (5.3%) in the control group;the peak velocity and mean velocity of lower-limb venous blood flow in the observation group were higher than those in the control group;the average length of stay in the observation group was less than that in the control group, and the satisfaction degree in the observation group was higher than that in the control group. The differences were statistically significant (P < 0.05). <strong>Conclusion:</strong> For patients who received renal biopsy, bundle care can help improve the peak velocity and mean velocity of venous blood flow, reduce the incidence of VTE, the average length of stay, and social costs, relieve their pain, and improve satisfaction degree of care;moreover, it plays an important role in reducing the incidence of deep venous thrombosis.展开更多

Study Design: A cohort study. Settings & Participants: Patients over 15 years of age who had been diagnosed with CKD according to the KDOQI (Kidney Disease Outcomes Quality Initiative) guidelines and who had undergone conventional treatment (CT) or a renal protection program (RPP). These were patients of two Colombian health insurance companies. Predictors: Age, sex, marital status, comorbidities, CKD stage, and clinical indicators. Outcomes: First CKD progression, and need for renal replacement therapy (RRT). Measures: Clinical marker. Results: The RPP is structurally and functionally different from the CT. It offers the interdisciplinary management of patients, a greater number of medical appointments, and patients start to receive treatment at younger ages and at earlier stages of their condition. The clinical markers of the patients following the RPP are within adequate ranges, and their renal function is less impaired, despite the differences in basal conditions. Upon finishing the study, we found that patients who received CT had a higher risk of receiving nephrotoxic drugs and not receiving nephroprotective drugs. The explanatory variables for the first progression were age, stage, history of dyslipidemia, and hemoglobin, potassium, and albumin levels. These variables, together with glycemia levels were also valid for RRT, except for history of dyslipidemia, as it was not significant. Upon adjusting for the explanatory variables, it was found that belonging to the RPP and attending more appointments had a protective effect in the process of controlling renal damage. Limitations: A possible selection bias. Conclusions: Belonging to a structured renal protection program is an effective way to keeping the clinical markers associated with renal impairment within normal ranges.展开更多

In chronic kidney failure, glyphosate-induced pancreatitis results in the release of trypsin, causing a leaky vasculature. The albumin-bound glyphosate escapes into the tissues, protecting the circulatory system and kidneys but resulting in multiple symptoms related to skin, gut, brain, bones, lungs, etc. The rare and poorly understood acute kidney failure response reported for protamine sulfate and Trasylol? is strikingly similar to that associated with glyphosate poisoning. Both drugs are derived from biological tissues that are plausibly contaminated with glyphosate. These drugs protect from haemorrhage, which leads to retention of glyphosate in the vasculature, are followed by circulatory collapse and a high likelihood of death as an outcome. We support our argument by comparing symptom profiles of selected subsets of FAERS with those related to glyphosate poisoning, anomalous reactions to protamine sulfate, and conditions showing strong statistical time-trend correlations with glyphosate.展开更多

文摘目的探讨肾小管及肾小球相关标志物在2型糖尿病(type 2 diabetes mellitus,T2DM)患者不同肾损伤阶段的诊断价值。方法选取于2018年4月1日至2019年10月31日入住首都医科大学附属北京同仁医院内分泌科的T2DM患者272例,完善临床生化指标及尿蛋白四项:尿微量白蛋白/肌酐(urinary albumin to creatinine ratio,ACR)、α1-微球蛋白/肌酐(urinary α1-microglobulin to creatinine ratio,UA1CR)、免疫球蛋白G/肌酐(urinary immunoglobulin G to creatinine ratio,UIGG)、转铁蛋白/肌酐(urinary transferrin to creatinine ratio,UTRF);进行眼底照相、核医学99mTc-EC检测肾有效血浆流量(effective renal plasma flow,ERPF)和99mTc-DTPA检测肾小球滤过率(glomerular filtration rate,GFR)。根据ACR和眼底检查结果分为4组:正常蛋白尿无糖尿病视网膜病变(diabetic retinopathy,DR)132例,即对照组(ACR≤30 mg/g);正常蛋白尿合并DR 32例,为糖尿病肾病(diabetic kidney disease,DKD)前期组;微量蛋白尿组78例(30<ACR≤300 mg/g)和大量蛋白尿组30例(ACR>300 mg/g)。比较四组间尿蛋白四项和ERPF、GFR的水平,通过受试者工作特征(receiver operating characteristic,ROC)曲线评价上述各指标在不同肾损伤阶段的诊断价值。结果尿蛋白四项和ERPF、GFR的水平在不同组间差异有统计学意义(P<0.05)。在尿蛋白正常组中,DR组中肾小管功能标志物UA1CR较对照组明显升高(P<0.01);肾小球功能标志物ACR、UTRF和GFR在两组间差异无统计学意义(P>0.05),DR组UIGG较对照组升高(P<0.01)。在微量蛋白尿组和大量蛋白尿组,尿蛋白四项随肾损伤程度增加而增加,而ERPF和GFR随肾损伤程度增加而降低。ROC曲线分析显示,在尿蛋白排出正常的T2DM患者中合并DR组中肾小管功能标志物UA1CR和ERPF的曲线下面积(area under the curve,AUC)分别为68.2%(P<0.01)和60.5%(P<0.05),而肾小球功能标志物ACR和GFR的AUC均小于60%,差异无统计学意义(P>0.05)。尿蛋白四项及GFR在微量和大量蛋白尿组的AUC均大于60%(P<0.05),ERPF在大量蛋白尿组AUC为67.2%(P<0.05)。结论T2DM极早期微血管改变即ACR正常仅有DR时,肾小管标志物UA1CR先于肾小球标志物ACR和GFR发生变化。肾损伤早期,肾小管标志物诊断效能优于肾小球;肾损伤后期,肾小球标志物诊断效能优于肾小管。提示DKD肾小管功能的改变可能早于肾小球。
