Objective To explore the relationship of glucagon in many phases with insulin and blood glucose in patients with insulin resistance syndrome,and to provide theory and practice support for the treatment of insulin resistance syndrome.Methods Totally 93 patients with insulin resistance syndrome (observation group),107 patients with type 2 diabetes (diabetes group) and 80 patients without diabetes (non-diabetes group) in our hospital from July 2008 to October 2011 were selected.The general information were collected.Patients with stable blood glucose stopped taking anti-diabetic drug for 10 hours.The fasting blood glucose,fasting insulin,and fasting glucagon were tested.Then patients took 75 g glucose,blood glucose,insulin and glucagon were respectively tested after 30 and 120 minutes.Data were processed by SPSS 17.0 software,and P＜0.05 was considered as being statistically significant.Results The levels of fasting glucose,early phase glucose and late phase glucose were lower in observation group than in diabetes group,but higher than in non-diabetic group,and the differences were statistically significant (all P＜0.05).The levels of fasting insulin,the early phase insulin,and late phase insulin were higher in observation group than in diabetes group and non-diabetic group,and the differences were statistically significant (both P＜0.05).The insulin levels in observation group and diabetes group were lowest after fasting and were highest at 120 minutes after the oral glucose load,but the insulin levels were highest at 30 minutes and decreased at 120 minutes after the oral glucose load in non diabetic group.The differences in fasting glucagon,early phase glucagon and late phase glucagon among three groups were statistically significant (all P＜0.05).The glucagon levels in observation group and diabetes group were lowest after fasting and highest at 120 minutes after the oral glucose load,but the glucagon levels in non-diabetic group were highest after fasting and were lowest at 120 minutes after the oral glucose load.There were positive correlations between glucagon and glucose in 3 phases in observation group (r=0.65,0.63,0.67,respectively,all P＜0.05).Conclusions Glucagon and glucose in different phases are positively correlated in patients with insulin resistance syndrome,and blood glucose can be controlled by improving glucagon secretion.%目的 探究B型胰岛素抵抗综合征患者多时相胰高血糖素与胰岛素、血糖的关系,为治疗极度胰岛素抵抗综合征患者提供理论和实践的支持. 方法 选取2008年7月至2011年10月在我院住院的B型胰岛素抵抗综合征患者(胰岛素抵抗组)93例,另选取2型糖尿病患者(糖尿病组)107例和非糖尿病者(非糖尿病组)80例进行比较.收集患者的一般临床资料,患者血糖平稳后停用降糖药物10 h,第2天空腹采血检测血糖、胰岛素、胰高血糖素,采血后即口服葡萄糖75 g,30 min、120 min后检测血糖、胰岛素、胰高血糖素. 结果 (1)胰岛素抵抗组与糖尿病组比较,空腹血糖、早时相血糖、晚时相血糖均降低,但均高于非糖尿病组,差异有统计学意义(P＜0.05)；(2)胰岛素抵抗组空腹胰岛素、早时相胰岛素、晚时相胰岛素与糖尿病组和非糖尿病组比较均升高,差异有统计学意义(P＜0.05)；胰岛素抵抗组和糖尿病组空腹胰岛素最低,120 min最高,而非糖尿组在30 min最高,120 min胰岛素分泌下降；(3)三组空腹胰高血糖素、早时相胰高血糖素、晚时相胰高血糖素之间比较,差异有统计学意义(P＜0.05),胰岛素抵抗组和糖尿病组空腹胰高血糖素最低,糖负荷120min最高；而非糖尿病组胰高血糖素的在空腹最高,而在30 min最低；(4)胰岛素抵抗组空腹、早时相和晚时相胰高血糖素与血糖呈正相关(r值分别为0.65、0.63、0.67,P＜0.05). 结论 B胰岛素抵抗综合征患者多时相胰高血糖素与血糖密切相关,改善胰高血糖素可有助于控制血糖.
