目的:探讨学龄期肥胖儿童肝X受体(LXR)与血脂代谢异常的相关因素。方法自2011年6月至10月,在1~6年级学生(7~14岁)中,通过体格发育指标检测,筛选出80例肥胖儿童和51例年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(t=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(χ2=17.01,P=0.000)。肥胖儿童的AST、ALT、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≥40 IU/L(OR=1.076),ALT≥40 IU/L(OR=1.036),CHOL≥5.20 mmol/L(OR=2.038),LDL-C≥3.36 mmol/L(OR=2.176)、BMI≥18.9 kg/m2(OR=1.131)均为LXR>1的危险因素(P均<0.05)。结论学龄期儿童肥胖可能促使体内LXR的表达量上调,导致肝损伤和血脂紊乱。
目的:探討學齡期肥胖兒童肝X受體(LXR)與血脂代謝異常的相關因素。方法自2011年6月至10月,在1~6年級學生(7~14歲)中,通過體格髮育指標檢測,篩選齣80例肥胖兒童和51例年齡與性彆匹配的正常對照兒童作為研究對象。取空腹靜脈血進行天鼕氨痠氨基轉移酶(AST)、丙氨痠氨基轉移酶(ALT)、穀氨酰轉肽酶(GGT)、總膽固醇(CHOL)、三酰甘油(TG)、高密度脂蛋白膽固醇(HDL-C)、低密度脂蛋白膽固醇(LDL-C)和LXR相對錶達量檢測。結果肥胖兒童LXR錶達量為(9.14±1.15),高于正常對照兒童的(2.84±3.68),差異有統計學意義(t=4.55,P=0.000);肥胖兒童中LXR>1比例為80.0%(64/80),高于正常對照兒童的45.1%(23/51),差異有統計學意義(χ2=17.01,P=0.000)。肥胖兒童的AST、ALT、GGT、CHOL、TG、LDL-C較正常對照兒童高,而HDL-C較正常對照兒童低,差異均有統計學意義(P<0.05)。LXR錶達與AST、ALT、CHOL、LDL-C和BMI水平均呈正相關(r=0.18~0.26,P均<0.05)。AST≥40 IU/L(OR=1.076),ALT≥40 IU/L(OR=1.036),CHOL≥5.20 mmol/L(OR=2.038),LDL-C≥3.36 mmol/L(OR=2.176)、BMI≥18.9 kg/m2(OR=1.131)均為LXR>1的危險因素(P均<0.05)。結論學齡期兒童肥胖可能促使體內LXR的錶達量上調,導緻肝損傷和血脂紊亂。

Objectives To explore the relevant factors of liver X receptor (LXR) and lipid metabolism in school-age chil-dren with obesity. Methods A total of 80 obese children were selected by indexes of physical growth from pupils in Grades 1-6, aged 7-14 years from June 2011 to October 2011. Fifty-one age and sex matched children with normal BMI were chosen as nor-mal controls. The metabolic indexes including aspartate transaminase (AST), alanine aminotransferase (ALT), glutamyl transpep-tidase (GGT), total cholesterol (CHOL), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipopro-tein cholesterol (LDL-C) and expression of LXR were detected in fasting blood. Results The expression level of LXR in obese children (9.14 ± 1.15) was higher than that in control children (2.84 ± 3.68) with significant difference (t=4.55,P=0.000). Eighty percent (80%) of obese children were LXR>1 (64/80) which was higher than that of control children (23/51, 45.1%), and signifi-cant difference was found between the two groups (χ2=17.01, P=0.000). Compared to controls, the levels of AST, ALT, GGT, CHOL, TG and LDL-C were higher while the level of HDL-C was lower in obese children (P<0.05). The correlation analysis found that AST, ALT, CHOL, LDL-C and BMI were positively correlated with LXR (r=0.18~0.26,P<0.05). Logistic regression ana-lysis showed that AST≥40IU/L (OR=1.076), ALT≥40IU/L (OR=1.036), CHOL≥5.20 mmol/L (OR=2.038), LDL-C≥3.36 mmol/L (OR=2.176) and BMI≥18.9 kg/m2 (OR=1.131) were risk factors for LXR>1 (P<0.05). Conclusions Obesity in school-age chil-dren can up-regulate the expression of liver X receptor and cause liver damage and abnormal lipids metabolism.
