冠心病患者血清IGF-I浓度检测的临床意义

目的探讨血清IGF-I浓度检测对估价冠心病患者左室功能及冠脉侧支循环状况的临床意义。方法应用放射免疫分析法检测4l例冠心病患者和15例正常人的血清IGF-I浓度;冠心病患者均行选择性冠状动脉造影,按Ren-trop法对侧支循环分级;左室造影测左室射血分数(LVEF)。结果冠心病患者组血清IGF-I浓度与正常对照组比较无显著性差异[(107.92±44.74)n/mLvs(113.05±33.65)n/mL,P＞0.05]。冠心病组中,IGF-I水平≥120ng/mL的A亚组LVEF及Rentrop侧支循环分级均显著高于IGF-I水平＜ 120ng/mL的B亚组(LVEF0.62±0.13vs0.5l±0.12,P＜0.01;Rentrop1.56±0.96vs0.12±0.33,P＜0.001)。IGF-I水平与LVEF(r=0.45,P＜0.001)及Rentrop侧支循环分级(r=0.74,P＜0.001)均呈显著正相关。结论较高的IGF-I水平可能提示冠心病患者有较好的左室功能和冠脉侧支循环;血清IGF-I浓度检测可作为估价冠心病患者左室功能及冠脉侧支循环状况的指标。

Objective To compare the efficacy of high and low dose atorvastatin on preventing contrast induced nephropathy (CIN) in patients underwent diagnostic and therapeutic coronary intervention. Methods All patients received atorvastatin 10 mg/d on the basis of hydrated therapy (n =100) and high dose group received additional atorvastatin 80 nag at 12 to 24 hours before procedure (n =50). Scr, Ccr, blood β2-M, urine NAG/Cr, and urine osmolality before and after the procedure were compared between the groups. Results Baseline demographic characteristics and nephropathy risk factors were similar between groups. Cer was significantly reduced while blood β2-M and uric NAG/Cr were significantly increased in low dose group (all P ＜ 0.05) . Blood β2-M in the high dose group was significantly lower than that in the low dose group at day 1 [(2.35±0.52) mg/L vs. (2.67±0.64) mg/L, P =0.008], day 3[(2.49±0.55)mg/L vs. (2.80±0.64) mg/L,P =0.011] and day 5[(2.29±0.53) mg/L vs. (2.56±0.66) nag/L, P = 0.026] post-procedure respectively; urine NAG/Cr in the high dose group was also significantly lower than that in the low dose group at day 1 [(1.19±0.30) U/mmol vs. (1.46±0.34) U/mmol, P ＜ 0.001], day 3 [(1.30±0.30) U/mmol vs. (1.59±0.33) U/mmol, P ＜ 0.001], and day 5 [(1.10±0.30) U/mmol vs. (1.34±0.35) U/mmol, P = 0.001] post-procedure respectively;Cer in the high dose group was significantly higher than that in the low dose group at day 1 [(73.69±20.99) mL/min vs. (65.19±18.72) mL/min,P =0.035], day 3[(64.04±15.82) ml/min vs. (56.79±14.50)ml/min,P =0.019] post-procedure respectively.

目的探讨胃肠激素含量变化与十二指肠溃疡的发生、发展的关系.方法十二指肠溃疡活动期(DU)患者共280例,男229例,女51例,平均36.12岁;健康成年人316例为对照组,男198例,女118例,平均40.29岁.采用RIA方法测定空腹血浆促胃液素(GAS)、胃动素(MTL)、内皮素(ET)、肾上腺髓质素(AM)、甘丙素(GAL)和降钙素基因相关肽(CGRP)水平.结果 DU患者空腹血浆GAS,MTL,ET和AM水平(pg/mL)较对照组明显升高,分别为74.64±18.50(n=178)与63.33±38.09(n=147),P＜0.01;496.80±102.11(n=30)与314.60±53.50(n=50),P＜0.05;41.12±3.73(n=16)与6.35±0.44(n=38),P＜0.01;115.51±27.01(n=15),P＜0.02.然而,二组血浆GAL和CGRP含量比较则表现为DU患者显著低于健康人,分别为1.84±0.63(n=21)与9.36±0.94(n=29)和3.89±1.58(n=20)与32.99±7.29(n=27),二者皆P＜0.001结论本文检测六种胃肠激素的血浆浓度,其含量变化可能在人体正常生理稳态调节中以及DU的发病和愈合过程中起着重要作用.
