Objectives To summarize the regulation of glucagon-like peptide-1（GLP-1） level by metabolism of gastrointestinal nutrients. Methods Domestic and international publications online involving regulation of GLP-1 level by metabolism of gastrointestinal nutrients in recent years were collected and reviewed. Results GLP-1 influenced insulin secretion and sensitivity， and played a leading role in recovery of glucose metabolism. Metabolism of gastrointestinal nutrients regulated GLP-1 level. Studies had shown that GLP-1 was a candidate mediator of the effects of gastric bypass （GBP） for type 2 diabetes mellitus（T2DM）. Conclusions It plays an important role in anti-T2DM effects of GBP that metabolism of gastrointestinal nutrients regulated GLP-1 level. The corresponding studies can provide a novel clinical field to treat T2DM.
In recent years, the field of transcatheter heart valve interventional therapy has developed rapidly. Valvular thrombosis is a rare postoperative complication, which can affect valvular function early or lead to clinical embolic events, and is gradually being valued by surgeons. The clinical manifestations of thrombosis after different types of interventional valve replacement are different. Although anticoagulant therapy is believed to be effective for valve thrombosis, the selection of anticoagulant drugs and the duration of anticoagulation are still controversial. This article reviews the definition, clinical features, prevention and treatment of valve thrombosis after several types of transcatheter heart valve replacement, mainly related to transcatheter aortic valve replacement and transcatheter mitral valve replacement, and aims to provide a reference for the diagnosis and treatment of valve thrombosis after transcatheter heart valve replacement.
Objective To investigate the management experience of type Ⅱ endoleak originating from inferior mesenteric artery (IMA) after endovascular abdominal aortic aneurysm repair (EVAR). Methods The clinical data of patients with type Ⅱ endoleak originating from IMA after EVAR were treated in the Department of Vascular Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University from October 2016 to November 2021 were collected and analyzed. Results There were 12 males and 3 females at age of 57-89 (68.00±7.84) years. Eleven patients received embolization of the abdominal aortic aneurysm lumen and initial segment of the IMA via the superior mesenteric artery-middle colic artery-Riolan arch-left colic artery-IMA route. Three patients received embolization of the initial segment of the IMA by the above route. One patient underwent open dissection of the abdominal aortic aneurysm, and orifice of IMA was sutured in the aneurysm cavity while stents were retained. All 15 patients were successfully treated by surgery. The symptoms of back pain, abdominal pain and abdominal distension disappeared in 6 patients after surgery. Neither perioperative deaths nor complications happened during the treatment and follow-up period. The median follow-up time was 11.00 (9.00, 18.00) months. Two patients with typeⅡendoleak recurred during the follow-up period and were admitted to hospital for secondary embolization. No recurrence was observed at 12 months postoperative follow-up. Conclusion Type Ⅱ endoleak is one of the most common complications after EVAR. IMA is the most common criminal origin of typeⅡendoleak. TypeⅡendoleak that lead to persistent expansion of the aneurysm cavity requires aggressive intervention.
摘要:目的:探讨创伤性感染性假性股动脉瘤的诊断和外科治疗的临床经验。方法:回顾性分析２１例创伤性感染性假性股动脉瘤的临床资料,均行瘤体摘除及彻底的清创后,分别采用了血管结扎术和血管修复重建术两种不同的手术治疗方法。结果:血管修复重建术组中３例术后出现血管破裂大出血,要再次手术,１５例行股动脉结扎术,全部保肢成功。结论:瘤体切除加血管移植术是一种理想的方法,但在无条件行血管移植时,股动脉结扎术可做为一种有效的方案,对伴有皮肤缺损者行对侧胸脐皮瓣转移术。Abstract: Objective: 〖WT5”BZ〗To explore the traumatic infected femoral pseudoaneurysm diagnosis and surgical treatment of clinical experience. Methods: Retrospective analysis of 21 cases of traumatic infected femoral pseudoaneurysm of the clinical data were performed and the tumor removed after thorough debridement, respectively vascular ligation and blood vessel repair and reconstruction surgery of two different surgical treatment. Results: The blood vessel repair and reconstruction surgery group, three cases of postoperative bleeding blood vessel ruptures occurred, we must resurgery, 15 routine femoral artery ligation, all of the success of limb salvage. Conclusion: The tumor resection plus vascular graft is an ideal way, but in an unconditional line of vascular grafts, the femoral artery ligation can be used as an effective program for skin defects associated with the contralateral breast underwent umbilical flap transfer of patients.
