三项尿蛋白相关检测在肾小球疾病中的诊断价值

目的探讨24小时尿蛋白、肾病指数及尿蛋白肌酐比对肾小球疾病的诊断价值。方法选取四川大学华西医院收治的疑似肾小球疾病患者71例(观察组),同期健康体检者71例(对照组),检测24小时尿蛋白、肾病指数及尿蛋白肌酐比情况。结果观察组三项尿蛋白相关测定诊断的准确度、灵敏度、特异度比较,差异无统计学意义(P>0.05);观察组三项尿蛋白检测水平均高于对照组(P<0.05)。观察组24小时尿蛋白与尿蛋白肌酐比、肾病指数呈正相关(P<0.05)。结论三项尿蛋白相关测定均可完成对肾小球疾病患者病情的掌握程度,可根据患者实际情况选择适宜的检测方法,提升检测效率。     

Comparison of Neoadjuvant and Adjuvant Chemotherapy in Muscle-invasive Bladder Cancer

BackgroundWe use observational methods to compare impact of perioperative chemotherapy timing (ie, neoadjuvant and adjuvant) on overall survival (OS) in muscle-invasive bladder cancer because there is no head-to-head randomized trial, and patient factors may influence decision-making.Patients and MethodsUsing Surveillance, Epidemiology, and End Results-Medicare data, we identified patients receiving cystectomy for muscle-invasive bladder cancer diagnosed between 2004 and 2013. Patients were classified as receiving neoadjuvant or adjuvant chemotherapy. Propensity of receiving neoadjuvant chemotherapy was determined using gradient boosted models. Inverse probability of treatment weighted survival curves were adjusted for 13 demographic, socioeconomic, temporal, and oncologic covariates.ResultsWe identified 1342 patients who received neoadjuvant (n = 676) or adjuvant chemotherapy (n = 666) with a median follow-up of 23 months (interquartile range, 9-55 months). Inverse probability of treatment weighted adjustment allows comparison of the groups head-to-head as well as counterfactual scenarios (eg, effect if those getting one treatment were to receive the other). The average treatment effect (ie, “head-to-head” comparison) of adjuvant compared with neoadjuvant on OS was not significant (hazard ratio, 1.14; 95% confidence interval, 0.99-1.31). However, the average treatment effect of the treated (ie, the effect if the neoadjuvant patients were to receive adjuvant instead) was associated with a 33% increase in risk of mortality if they were given adjuvant therapy instead (hazard ratio, 1.33; 95% confidence interval, 1.12-1.57).ConclusionSignificant treatment selection bias was noted in peri-cystectomy timing, which limits the ability to discriminate differential efficacy of these 2 approaches with observational data. However, patients with higher propensity to receive neoadjuvant therapy were predicted to have increased OS with approach, in keeping with existing paradigms from trial data.     

Comparison of urinary amino acid excretory pattern in patients with type 2 diabetes mellitus and non-diabetic healthy controls at a tertiary referral hospital in India

AimSpecific amino acids have been linked to regulation of insulin secretion from pancreatic β-cells; on the contrary, increased concentration of certain amino acids is associated with insulin resistance (IR) and development of type 2 diabetes mellitus (T2DM). Nowadays, urine as a biological sample has attracted more attention for diagnosis of disease for its special superiority; insufficient research in the study of urinary amino acid (UAA) pattern in patients with T2DM has led to the present study with the aim to determine the levels of UAAs, their excretory patterns and the association of UAA to plasma glucose and IR in patients with T2DM.MethodsQuantification of total urinary amino acids was done spectrophotometrically and the patterns of amino acid excretion was elucidated by thin layer chromatography technique. Fasting blood samples were used for plasma glucose and insulin estimation by fully automated analyzer.ResultThe levels of UAA in patients with T2DM in comparison to healthy controls were higher (p < 0.0001). The frequency of urinary phenylalanine, arginine, tryptophan, tyrosine and cysteine were significantly higher in patients with T2DM than controls. There was also a strong positive correlation of UAA levels with blood glucose levels and HOMA–IR in patients with T2DM.ConclusionOur study has shown subtle abnormalities in UAA patterns in patients with T2DM. The measurement of UAA levels and excretory pattern can be used as an index of hyperglycemia and IR which could serve as an inexpensive and non-invasive marker for T2DM. More studies are required to confirm this association.
