青岛地区高尿酸血症患者的肠道菌群分析

Analysis of intestinal flora in patients with hyperuricemia in Qindao District

目的 观察青岛地区高尿酸血症患者肠道菌群的变化及菌群对尿酸处理能力的相关性分析.方法 收集2013年1月至2013年6月在本院内分泌门诊就诊的高尿酸血症患者30例（男28例,女2例）及同期在健康查体中心查体的健康对照组粪便标本20例（男16例,女4例）.应用细菌培养方法进行粪便菌群分析,运用酶比色法检测不同组粪便中细菌分解前后尿酸含量变化,磷钨酸法检测血尿酸水平.结果 高尿酸血症患者肠道菌群发生变化,表现为总需氧菌（7.76 ±0.67,P＜0.05）、大肠杆菌（7.58 ±0.34,P＜0.05）及拟杆菌（2.75 ±0.31,P＜0.05）增加,乳酸杆菌（2.69±1.48,P＜0.05）及双歧杆菌（5.38 ±0.34,P＜0.05）数目减少.血及粪便中尿酸含量升高（P＜0.05）,粪便菌群尿酸处理能力与健康对照组比较差异无统计学意义（P＞0.05）.粪便菌群尿酸分解活性主要与乳酸杆菌及双歧杆菌含量呈正相关（r =0.565,0.328,P＜0.05）.结论 青岛地区高尿酸血症患者肠道菌群存在失调现象,粪便菌群尿酸处理能力与乳酸杆菌及双歧杆菌含量有关.菌群失调可能参与高尿酸血症的发病过程.

Objective To investigate the variations of intestinal flora of common carp in patients with hyperuricemia in Qingdao District.Methods The fecal flora was analyzed by gradient dilution method.The levels of uric acid in blood and feces were detected by enzyme colorimetry method and phosphortungstic acid method,respectively.Results E.coli （7.58 ± 0.34,P ＜ 0.05）,the total count of aerobian （7.76 ± 0.67,P ＜ 0.05）,and bacteroides （2.75 ± 0.31,P ＜ 0.05） were significantly increased in hyperuricemia patients compared to controls.Bifidobacterium （5.38 ± 0.34,P ＜ 0.05） and lactobacillus （2.69 ± 1.48,P ＜ 0.05） were sig-nificantly decreased compared to controls.Concentrations of uric acid in blood and feces were both significantly higher in the patients relative to healthy controls.Decomposition capability was similar to healthy controls.Decomposition capability of uric acid revealed a close correlation with bifidobacterium and lactobacillus,respectively （r =0.565,0.328,P ＜ 0.05）.Conclusions Intestinal dysbacteriosis was found by the analysis of fecal flora in patient with hyperuricemia in Qingdao district.Dysbacteriosis might participate in the process of hyperuricemia onset.
