Surgical treatment of post—traumatic pseudoaneurysms and arteriovenous fistulas

Objective:To report the experience in the diagnosis and treatment of post-traumatic pseudoaneurysms and arteriovenous fistulas.Methods:A series of 30 patients(11 women and 19 men) with posttraumatic pseudoaneurysms were reviewed retrospectively.Among them 7 patients (5 women and 2 men) were associated with arteriovenous fistula.Results:The causes included sharp penetration trauma(18 cases),blunt trauma (6 cases) and iatrogenic arterial injury (6 cases).The main clinical manifestations consisted of local pulsatile mass (26 cases),vascular bruits (19 cases),thrill (13 cases),ischemia of distal limb (9 cases),neuropathy (5 cases) and pseudoaneurysm rupture (2 cases).All patients underwent surgery.The operations included:ligation of the vessels (12 cases),surgical resection and primary suture repain of the vascular defect or anastomosis (11 cases),vascular reconstruction with autogenous saphenous vein (3 cases) and synthetic vascular graft (4 cases).Conclusions:Because of the imminent clinical course,early operation is usually indicated.The operative treatment is effective and safe for most of the patients with post-traumatic pseudoaneurysms and arteriovenous fistulas.     

Ki-67抗原在胆囊良恶性肿瘤中的表达

目的 观察Ｋｉ－６７抗原在胆囊良恶性肿瘤中的表达强度与肿瘤的分级分期、治疗效果和预后的关系。方法 采用免疫组织化学（ＡＰＡＡＰ）方法,用抗人Ｋｉ－６７抗原的等８效抗体ＭＩＢ－１比较研究Ｋｉ６７蛋白在良恶性胆囊肿瘤和正常胆囊组织中的表达情况,对比较不同胆囊组织中细胞增殖的情况。结果 Ｋｉ－６７蛋白在胆囊癌组织中表达的阳性指数率显著高于胆囊良性肿瘤及正常胆囊组织（Ｐ〈０．０５）。但Ｋｉ－６７蛋白的表达     

新冠肺炎疫情下黑龙江省一线防疫人员心理健康状况及影响因素研究

目的：了解新冠肺炎疫情下黑龙江省一线防疫人员心理健康状况,为开展心理干预服务提供理论依据。方法：于2021年1月16—31日采用广泛性焦虑量表和抑郁症筛查量表对黑龙江省一线防疫人员心理健康状况进行评估。结果：共收集有效问卷369份,广泛性焦虑量表评估得分为（5.31±4.72）分,抑郁症筛查量表评估得分为（5.22±4.97）分。女性、较低年龄组、大专及以下学历、初级职称、无传染病防控经验人员、已婚人员、于一线工作时间较长者、每日工作时间较长者更易出现焦虑状态,差异有统计学意义（Z值分别为16.674、80.938、8.485、172.958、14.858、178.954、-6.388和208.508,P值均<0.01）;女性、较低年龄组、大专及以下学历、初级职称、无传染病防控经验人员、已婚人员、于一线工作时间较长者、每日工作时间较长者、从事核酸检测人员更易产生抑郁情绪,差异有统计学意义（Z值分别为-4.939、69.228、9.350、170.530、188.984、-12.289、-6.336、173.314和8.779,P值均<0.01）。结论：新冠肺炎疫情期间一线防...
