目的：探討超聲診斷對異位妊娠的診斷及臨床價值。方法：回顧性總結分析85例經臨床確診的異位妊娠。結果：輸卵管壺腹部、峽部及傘部妊娠75例，符合率95.8%；間質部妊娠2例，符合率100%；卵巢妊娠1例，為誤診；宮角妊娠2例，符合率100%；宮頸妊娠5例，符合率100%；未破裂型異位妊娠51例，不典型34例。結論：超聲檢查對異位妊娠能作出較準確的定位診斷，對臨床治療提供了有力證據，具有較高的臨床診斷價值。
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.
【摘要】 目的 了解老年門診患者癡呆癥的發生率及其相關危險因素。方法 對2007年7月—2009年5月,年齡≥60歲644例門診患者進行簡易智能表(MMSE簡易評分)評價,并收集患者文化程度、吸煙、基礎疾病、用藥史進行危險因素相關分析。結果 樣本人群老年癡呆癥的發病率為16.0%。與老年性癡呆密切相齡、高血壓、腦卒中史、聽力受損和視力受損。結論 高齡、高血壓、腦卒中是老年性癡呆主要的危險因素,當前的醫療衛生機構應該積極有效地采取措施,控制可變因素,減少老年性癡呆的發生。
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.
