大承气汤对大鼠胃大部切除术后胃瘫及相关胃肠激素的影响

目的:观察大承气汤对大鼠胃大部切除术后胃肠动力及相关胃肠激素的影响。方法:SD大鼠30只,随机分为三组,即:空白组、模型组、治疗组。除空白组外,其余大鼠给予胃大部切除手术,造模后8d,治疗组给予大承气汤灌胃(100%大承气汤煎剂10mL/kg,2次/d),连续灌胃7d。之后所有动物给予酚红灌胃,观察各组动物的胃排空率和小肠推进率变化。同时采血,ELISA法检测血清胃泌素、胃动素的变化。结果:模型组大鼠胃排空率、小肠推进率、血清胃动素水平明显低于空白组(P<0.01),而血清胃泌素较空白组高(P<0.01);大承气汤治疗组胃排空率、小肠推进率、血清胃动素水平均明显高于模型组(P<0.01),血清胃泌素较模型组低,具有明显差异(P<0.01)。结论:大承气汤能够明显改善胃大部切除术后胃肠功能的恢复,其机制与促进胃动素、胃泌素的分泌有关,具有防治胃大部切除术后胃瘫的功效。

Deep venous thrombosis after gastrectomy for gastric carcinoma:A case report

The treatment of gastric carcinoma consists of neoadjuvant chemoradiation,partial gastrectomy,subtotal gastrectomy,total gastrectomy,extended resection,and postoperative chemotherapy.Currently,gastrectomy and extended lymphadenectomy is the optimal choice for late gastric carcinoma.Postoperative complications are common after total gastrectomy including hemorrhage,anastomotic leakage,f istula,and obstruction.However,deep venous thrombosis(DVT) is an uncommon complication after gastrectomy for gastric carcinoma.We describe a case of a 68-year-old female patient with DVT after gastrectomy for gastric carcinoma.The patient was treated with anticoagulants and thrombolytics and subjected to necessary laboratory monitoring.The patient recovered well after treatment and was symptom-free during a 3-mo follow-up.We conclude that correct diagnosis and treatment of DVT are crucial.
