  • Safety Assessment of Low Molecular Heparin Instead of Anticoagulant in Patients with Inguinal Hernia during Perioperative Period

    ObjectiveTo evaluate the safety and efficiency of perioperative low molecular heparin (LMH) as the replacement of anticoagulant for patients with inguinal hernia. MethodsSixty-three patients with oblique inguinal hernia from April 2009 to April 2012 in this hospital were analyzed retrospectively.Seventeen cases because of other diseases were long-term oral aspirin anticoagulant therapy (aspirin group), 11 cases because of other diseases were long-term oral warfarin anticoagulant therapy (warfarin group), anticoagulant therapy was replaced by continuing LMH 7 d before operation in the aspirin group and the warfarin group.The other 35 cases did not take any anticoagulant therapy (control group). Results①The demography and preoperative international normalized ratio were similar among three groups (P > 0.05).②All the patients were followed-up.The duration of follow-up ranged from 12 months to 18 months.There were no statistical differences of the scrotal hematoma or subcutaneous hematoma, operation time, postoperative hospital stay, and VAS scoring among these three groups (P > 0.05).There was no recurrence in all the patients. ConclusionFor a long term application of anticoagulant in patients with oblique inguinal hernia, perioperative application of LMH instead of anticoagulant does not increase the risk of bleeding, and could prevent thrombosis.

  • The Expression of Transthyretin and Its Nucleating Role in Tissues of Human Gallbladder with Cholesterol Stones

    ObjectiveTo explore the expressions of transthyretin(TTR) mRNA and its protein in tissues of human gallbladder with cholesterol gallstones, and to explore its role in the formation of cholesterol gallstones. MethodsGallbladder were got from cases of cholesterol gallstones(cholesterol gallstones group, n=25) and cases underwent liver transplantation with normal gallbladder(normal control group, n=9) respectively, who were treated in Ren Ji Hospital and Huashan Hospital. Real time PCR(RT-PCR) and Western blot method were used to determine the expressions of TTR mRNA and its protein respectively. In addition, 2 kinds of artificial model bile system were established to test nucleation time(NT) and nucleation activity, which added TTR and albumin(ALB). ResultsThe expression levels of TTR mRNA and protein in cholesterol gallstones group were 1.51±0.78 and 3.95±0.09 respectively, which were both higher than those of normal control group(P<0.05). The NT were(14.5±1.3)d and(18.0±0.8)d in TTR group and ALB group in small model bile system(P<0.01), which was similar with comprehensive model bile system[(13.5±0.6)d vs. (18.5±1.3)d]. The nucleation activity were 0.81 and 0.73 in small model bile system and comprehensive model bile system respectively. ConclusionsExpression of TTR up-regulates in human gallbladder tissues of patients with cholesterol gallstones, and TTR plays role of nucleation in model bile system, which is related to the formation of cholesterol gallstones.
