目的：探讨超声诊断对异位妊娠的诊断及临床价值。方法：回顾性总结分析85例经临床确诊的异位妊娠。结果：输卵管壶腹部、峡部及伞部妊娠75例，符合率95.8%；间质部妊娠2例，符合率100%；卵巢妊娠1例，为误诊；宫角妊娠2例，符合率100%；宫颈妊娠5例，符合率100%；未破裂型异位妊娠51例，不典型34例。结论：超声检查对异位妊娠能作出较准确的定位诊断，对临床治疗提供了有力证据，具有较高的临床诊断价值。
【摘要】 目的 了解老年门诊患者痴呆症的发生率及其相关危险因素。方法 对2007年7月—2009年5月,年龄≥60岁644例门诊患者进行简易智能表(MMSE简易评分)评价,并收集患者文化程度、吸烟、基础疾病、用药史进行危险因素相关分析。结果 样本人群老年痴呆症的发病率为16.0%。与老年性痴呆密切相龄、高血压、脑卒中史、听力受损和视力受损。结论 高龄、高血压、脑卒中是老年性痴呆主要的危险因素,当前的医疗卫生机构应该积极有效地采取措施,控制可变因素,减少老年性痴呆的发生。
Objective To analyze the hot topics and trends of medical research integrity in China and to provide references for future studies. Methods The CNKI, WanFang Data and VIP databases were searched from inception to December 2021. Data on the number of publications, journals, institutions, authors, keywords, and emergent themes were analyzed using bibliometric methods and CiteSpace software. Results A total of 324 studies were included. The results showed that the number of publications increased annually, and "Chinese Journal of Medical Science Research Management" and Peking University were the journal and institution with the most publications, respectively. The three most prolific authors published five studies each, and the publications were mainly concerned with identifying and preventing issues, in addition to education regarding medical research integrity. Conclusion Medical research integrity in China has attracted significant attention. Several leading journals in this research field have emerged; however, there is no clearly dominant research team. The depth and breadth of the research remain to be improved. It is suggested that researchers focus on the effectiveness of strategies for preventing issues, promoting the establishment of the lifelong education system and improving related rules and regulations to advance the development of medical research integrity in China.
ObjectiveTo explore the surgical treatment of deep chest wall infection, improve the cure rate and reduce the recurrence rate.MethodsThe clinical data of 655 patients with deep chest wall infection treated in Yanda Hospital and Beijing Royal Integrative Medicine Hospital from June 2015 to June 2020 were retrospectively analyzed. There were 450 males and 205 females, aged 55.6±12.8 years. There were 8 patients with chest wall infection after tumor necrosis, 15 patients after radiotherapy and 632 patients after thoracotomy (612 patients after cardiovascular surgery and 20 patients after general thoracic surgery). Among them, 649 patients underwent debridement and reconstruction of chest wall defect with muscle flap.ResultsThe average operation time was 95±65 min, the average intraoperative blood loss was 180±100 mL, and the average postoperative hospital stay was 13±6 d. Of the 649 patients who underwent muscle flap reconstruction after debridement, 597 patients recovered within 2 weeks, and the primary wound healing rate was 94.4%. Twenty-three (3.5%) patients died. The median follow-up time was 25 (2-40) months. Among the remaining 632 patients, 20 recurred, with a recurrence rate of 3.1% (20/632).ConclusionPedicled muscle flap after thorough debridement of deep chest wall infection is one of the best methods to repair chest wall defect with pedicled muscle flap.
