目的 观察秦绵祛风胶囊对鹌鹑高尿酸血症的影响。 方法 通过喂饲用酵母配制的造模饲料造成鹌鹑高尿酸血症模型,设秦绵祛风胶囊高、中、低3个剂量组并以苯溴马隆为阳性对照,在造模的同时连续灌胃药35 d,检测血中黄嘌呤氧化酶、尿酸、血尿素氮和三酰甘油及粪便中尿酸含量。 结果 模型动物血清中黄嘌呤氧化酶、尿酸和三酰甘油水平及粪便中尿酸含量较正常对照组明显升高。秦绵祛风胶囊各剂量组均可显著降低鹌鹑血清中的尿酸和三酰甘油水平,同时升高粪便中尿酸含量,对血清中黄嘌呤氧化酶活性影响不大。 结论 秦绵祛风胶囊具有降脂降尿酸的功能,其机制可能是通过提高动物排泄尿酸的能力,从而降低血中尿酸的含量。
Uric acid (UA) is the final product of human purine metabolism. As one of the main antioxidants in the body, it can scavenge oxidative radicals. Under the action of oxidative-antioxidant shuttle mechanism, the antioxidant activity of UA can be reversed, causing inflammation and oxidative stress of vascular endothelial cells. Hyperuricemia (HUA) is considered to be one of the major risk factors for diabetes and diabetic nephropathy. The study of HUA in diabetic retinopathy (DR) is also a hot topic. UA can cause retinal vascular sclerosis, and affect the occurrence and development of DR by promoting oxidative stress and inducing neovascularization.
摘要:目的: 系统评价非布索坦治疗痛风的疗效及安全性。 方法 :计算机检索PubMed、EMBASE、SCI、CBM、CNKI、VIP、万方数据库及Cochrane图书馆,手工补充检索;纳入非布索坦治疗痛风的随机对照试验(RCT);进行方法学质量评价和Meta分析。 结果 :共纳入3个RCT(受试者1985例),A级文献1篇,B级文献2篇。Meta分析结果显示:最后3月血清尿酸(SU)持续低于60 mg/dl患者数、随访结束时SU低于60 mg/dl患者数非布索坦组与对照组差异均有统计学意义;治疗相关不良事件发生数与安慰剂组差异无统计学意义,与别嘌呤组差异有统计学意义。 结论 :基于当前证据,非布索坦治疗痛风,能有效降低SU含量,减少治疗相关不良事件发生率。Abstract: Objective: Assessing the effectiveness and safety of febuxostat for the treatment of gout. Methods :Randomized controlled trails(RCT) of febuxostat for the treatment of gout were gathered from the Cochrane Library、PubMed、EMBASE、SCI、CBM、CNKI、VIP、Wangfang Database, other relative researches were handsearched, each RCT was methodological quality evaluated, then analyzed by software RevMan50 Results :A total of 3 RCTs were collected (involving 1985 subjects); 1 was graded A, 2 were B; according to the Metaanalysis: the differences of subjects with last 3 monthly serum urate(SU)<60mg/dl and subjects with SU<60mg/dl at final visits were significant; treatmentrelated adverse events between febuxostat and allopurinol was significant different, but not significant difference between febuxostat and placebo. Conclusion : According to the evidence currently, febuxostat could reduce SU and the episodes of treatmentrelated adverse events.
Objective To study the risk factors of hyperuricemia in patients with mild coronary artery stenosis. Methods The clinical data of 267 patients, who underwent coronary angiography, were collected and classified into the hyperuricemia group (58.5±8.0 years) and the normal control group (57.3±9.9 years). The coronary artery diameter stenosis of all the patients was lower than 50%. Results Elevated levels of body mass index (BMI), serum creatinine, triglyceride, low level of high-density lipoprotein, and history of hypertension or diabetes mellitus were significantly correlated with increased prevalence of hyperuricemia in patients with mild coronary artery stenosis. Multivariate logistic regression models found that the risk factors were diabetes mellitus (OR=1.999, 95%CI 1.087 to 3.678) , BMI (OR=1.110, 95%CI 1.009 to 1.221), hypertriglyceridemia (OR=1.237, 95%CI 1.023 to 1.496), and serum creatinine (OR=1.026, 95%CI 1.008 to 1.045). Conclusion Diabetes mellitus, BMI, hypertriglyceridemia and serum creatinine are independent risk factors of hyperuricemia in patients with mild coronary artery stenosis.
Objective To compare the efficacy and safety of benzbromarone vs. allopurinol for primary gout. Methods Searching PubMed, Cochrane Library, EMbase, CNKI, VIP and CBM, randomized controlled trials were collected and the quality of RCTs was evaluated using Cochrane systematic review. Meta-analysis was performed. Results 6 RCTs were included in this study,with a total of 350 patients. Meta-analysis showed that there was no statistical significance in total effective rate between two groups (Pgt;0.05). 4 RCTs were enrolled in comparison of ADR. There was statistical significance between two groups (Plt;0.05). Conclusion There is no significant difference in the efficacy between benzbromarone and allopurinol for the primary gout.But benzbromarone is safe than allopurinol for primary gout .
Objective To assess the efficacy and safety Losartan for essential hypertension associated withhyperuricemia. Methods Included randomized controlled trials of Losartan versus Valsartan. Electronic searchconducted in CENTRAL, the Cochrane Library (until 2008, Issue 4), PubMed, EMBASE, Chinese Biomedicine database,Chinese Scientific Journals Full-text Database, and China Journal Full-text Database (until 2008, Issue 10). Two reviewers extracted data independently. RevMan 5.0 software developed by the Cochrane Collaboration was used for Metaanalysis.Results Only 7 trials with 1 136 eligible patients were included in the systematic review. Meta-analysis showedno significant difference in reductions of systolic blood pressure, diastolic blood pressure, and adverse events betweenLosartan and Valsartan groups. However, a significant difference of serum uric acid reduction was observed betweenLosartan and Valsartan group. Losartan play a significant role of decreased serum uric acid levels. Conclusions Based on this systematic review, Losartan is effective and well tolerated in reducing BP and serum uric acid levels. Further large randomized, double blind, placebo controlled trials are needed in long-term safety and efficacy and different subgroups of Losartan.
目的 探讨成都地区高尿酸血症发生的危险因素。 方法 收集2009年10月-2010年4月在四川大学华西医院体检中心进行健康体检的36 639人的临床资料,对资料进行单因素分析和多因素logistic回归分析。 结果 进行健康体检的36 639人,其中男21 175人,女15 464人。高尿酸血症患者5 233例,患病率为14.3%。年龄>50岁、男性、饮酒、糖尿病、高血压病、甘油三酯增高、低密度脂蛋白增高和血清肌酐水平增高与高尿酸血症的发生有关。Logistic回归分析显示男性(OR=13.300,P=0.000)、饮酒(OR=4.219,P=0.009)、糖尿病(OR=3.609,P=0.024)是发生高尿酸血症独立危险因素。 结论 成都地区高尿酸血症的患病率略高于全国平均水平,临床治疗和护理高尿酸血症的患者时应积极控制与高尿酸血症发生密切相关的危险因素。
