摘要
目的研究肝硬变门静脉高压症患者行门腔静脉分流术后血浆胰高血糖素（ｇｌｕｃａｇｏｎ，Ｇｌｃ）水平的变化。方法应用放射免疫分析法测定了１６例肝硬变门静脉高压症行门腔静脉分流术和１６例对照组患者血浆Ｇｌｃ水平。结果肝硬变组Ｇｌｃ水平（ｐｇ／ｍｌ）术前、术中比术后３天、术后７天，门静脉血：（１８９２±５８７）ｐｇ／ｍｌ、（１９６１±５４２）ｐｇ／ｍｌｖｓ．（１０１９±４４８）ｐｇ／ｍｌ、（９８２±３４１）ｐｇ／ｍｌｖｓ．（Ｐ＜００１）；周围静脉血：（１８４１±４８２）ｐｇ／ｍｌ、（１８７５±４２８）ｐｇ／ｍｌｖｓ．（１０２４±３４７）ｐｇ／ｍｌ、（９５２±２４９）ｐｇ／ｍｌ，（Ｐ＜００１）；动脉血为：（１８６３±５１３）ｐｇ／ｍｌ、（１８３５±５４２）ｐｇ／ｍｌｖｓ．（１０３４±３６３）ｐｇ／ｍｌ、（９３９±３０６）ｐｇ／ｍｌ（Ｐ＜００１）；肝硬变组门静脉血中Ｇｌｃ水平与门静脉压力呈明显正相关（ｒ＝０５７，Ｐ＜００１）。结论肝硬变门静脉高压症患者的Ｇｌｃ血症与胰腺及胃肠道产生Ｇｌｃ增加和肝脏代谢Ｇｌｃ降低有关；门腔静脉分流术有助于改善肝硬变门静脉高压症患者Ｇ?
Objective To investigate the plasma level of glucagon in cirrhotic patients with portal hypertension during operation of portalcaval shunts. Methods Plasma level of glucagon in the portal venous, peripherial venous and arterial blood in cirrhotic patients( n =16) and control patients( n =16) was measured by radioimmunoassay respectively. Results The glucagon ratio (pg/ml) of the hepatic cirrhosis group before, during after operation 3 days after operation, 7 days after operation was observed portal venous blood:(189 2±58 7) pg/ml,(196 1±54 2) pg/ml vs. (101 9±44 8) pg/ml,(98 2±34 1) pg/ml ( P <0 01); peripherial venous blood (184 1±48 2) pg/ml,(187 5±42 8) pg/ml vs. (102 4±34 7) pg/ml,(95 2±24 9) pg/ml ( P <0 01); arterial blood:(186 3±51 3) pg/ml,(183 5±54 2) pg/ml vs. (103 4±36 3) pg/ml,(93 9±30 6) pg/ml( P <0 01). The portal vein pressure was positively correlated to the plasma level of glucagon in portal venous blood of cirrhosis ( r =0 57, P <0 01). Conclusions Hyperglucagonemia may be caused by the decreased glucagon metabolism in cirrhotic liver and hypersecretion of pancreas and the gastrointestinal tract. Hyperglucagonemia may be amended after portalcaval shunts.
