2、龄与性别匹配的正常对照儿童作为研究对象。取空腹静脉血进行天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、谷氨酰转肽酶(GGT)、总胆固醇(CHOL)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)和LXR相对表达量检测。结果肥胖儿童LXR表达量为(9.14+1.15),高于正常对照儿童的(2.84+3.68),差异有统计学意义(=4.55,P=0.000);肥胖儿童中LXR>1比例为80.0%(64/80),高于正常对照儿童的45.1%(23/51),差异有统计学意义(=17.01,P=0.000)。肥胖
3、儿童的AST、AIJr、GGT、CHOL、TG、LDL—C较正常对照儿童高,而HDL—C较正常对照儿童低,差异均有统计学意义(P<0.05)。LXR表达与AST、ALT、CHOL、LDL-C和BMI水平均呈正相关(r=0.18~0.26,P均<0.05)。AST~>40IU/L(OR=I.076),ALTo>40IU/L(OR=1.036),CHOL~>5.20mmol/L(OR=2.038),LDL—c≥3.36mmol/L(OR=2.176)、BMI~18.9kg/m(OR=1.131)均为LXR>l的危险因素(P均4、可能促使体内LXR的表达量上调,导致肝损伤和血脂紊乱。关键词:肥胖;学龄期儿童;x受体;代谢异常CorrelationofliverXreceptorandabnormallipidmetabolisminschool-agechildrenwithobesityZHUQingling.YEginhua2,YANGShengpingi2LIUQian2.CHENHong2《1.TheFirstClinicalMedicineCollegeofLanzhouUniversity,"2.TheFirstHospitalofLanzhouUniversity5、,Lanzhou730000,Gansu,ChinAbstract:0bjeetivesToexploretherelevantfactorsofliverXreceptor(LXR)andlipidmetabolisminschool—agechil—drenwithobesity.MethodsAtotalof80obesechildrenwereselectedbyindexesofphysicalgrowthfrompupilsinGrades1-6,aged7—14yearsfromJune2011tOOctober2011.Fifty-on6、eageandsexmatchedchildrenwithnormalBM1werechosenasnor·malcontrols.Themetabolicindexesincludingaspartatetransaminase(AST),alanineaminotransferase(ALT),glutamyltranspep—tidase(GGT),totalcholesterol(CHOL),triacylglycerol(TG),highdensitylipoproteincholesterol(HDL—C),lowdensitylipopr7、o—teincholesterol(LDL—C)andexpressionofLXRweredetectedinfastingblood.ResultsTheexpressionlevelofLXRinobesechildrenf9.14+1.15)washigherthanthatincontrolchildrenf2.84+3.68)withsignificantdiference(I=-4.55,P-0.ooo).Eightypercent(80%)ofobesechildrenwereLXR>1(64/80)whichwashigherthan8、thatofcontrolchildren(23/51,45.1%),andsignifi—c
