Objective To explore the hemostatic effect of a novel mammalian-derived bioadhesive in partial liver resection in rats.Methods The model of the left lateral lobectomy in SD rats established earlier was used in this study.The rats were divided into model group,test group and positive control group,with 10 rats in each group.The novel mammalian-derived bioadhesive and porcine fibrin sealant were sprayed on the wound in the test group and positive control group,respectively.The hemostatic effect was evaluated by calculating the amount and time of bleeding.Results Compared with the model group[(504.6±190.0)s,(194.4±144.2)mg],the bleeding time[(96.1±26.4)s,(4.8±17.8)mg]and the amount of bleeding[(156.7±139.3)s,(47.8±121.3)mg]were significantly shortened in the test group and positive control group(P<0.01).There was no significant difference in the bleeding time and the amount of bleeding between the positive control group and test group(P>0.05).Conclusion The novel mammalian-derived bioadhesive can reduce bleeding and shorten bleeding time in rat models with partial liver resection.In clinical practice,it can reduce hemostatic procedures,thereby shortening the surgical time and achieving the goal of sealing and hemostasis

'Social beings' model of standardized training program for residents in Shanghai is one of the important measures in the health care reform. According to the requirements of the standardized training of residents in thoracic surgery, the article preliminarily explored the standardized training model for residents from four aspects such as individualized treatment of different professional backgrounds, focus-ing on the training needs of residents with different starting point of social beings, developing training programs for different training time and combining the master's degree graduate education. And based on the characteristics of thoracic surgery, it also summed up the past experience and explored the clinical practice teaching.
