  • 人工髋关节置换术后股骨骨折原因分析与治疗

    目的 总结人工髋关节置换术后股骨骨折的原因及处理方法。 方法 2005 年3 月- 2010 年1 月,收治18 例人工髋关节置换术后股骨骨折患者。男8 例,女10 例;年龄45 ~ 70 岁,平均64 岁。关节置换术后5 ~ 48 个月发生股骨骨折。17 例有外伤史,1 例为自发性骨折。股骨骨折后1 ~ 32 d 入院。骨折采用Vancouver 分型标准:A型1 例,B1 型7 例,B2 型5 例,B3 型3 例,C 型2 例。术前Harris 评分为(50.4 ± 4.1)分。根据不同骨折分型,分别采用保守治疗、骨折固定、假体翻修、自体髂骨植骨等方法治疗。 结果 手术患者术后切口均Ⅰ期愈合。除1 例患者因合并慢性心功能不全及脑梗死,行皮牵引治疗后2 个月死亡外,余17 例均获随访,随访时间12 ~ 49 个月,平均23 个月。X 线片复查示骨折于术后12 ~ 32 周达临床愈合。术后6 个月Harris 评分为(87.5 ± 3.4)分,与术前比较差异有统计学意义(t=2.241,P=0.021)。 结论 人工髋关节置换术后股骨骨折成功治疗的关键是全面评估患者情况,根据Vancouver 分型标准确定治疗方案,可获得满意临床疗效。

  • Bibliometric analysis of studies on medical research integrity in China

    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.

  • Modified Total Arch Replacement for 38 Patients with Stanford A aortic dissection

    ObjectiveTo achieve a better early clinical result by modifying the total arch replacement and optimi-zing the procedure of operation. MethodWe retrospectively analyzed the clinical data of 38 patients patients with stanford a aortic dissection underwent the modifed total arch replacement in our hospital from September to December 2014. There were 26 males and 12 females with a mean age of 52.5 years ranging from 21-76 years. Three artery conduits were adopted during the surgical procedure. Right axillary artery and femoral artery cannulation were performed for cardiopulmonary bypass. The artificial graft and the left common carotid artery was anastomosed to provide simultaneous perfusion. Low rate bilateral brain perfusion began when circulation arrested at 26℃. Reperfusion restoration was obtained after the four-branch vascular graft anastomosed to the stent and aortic wall and completed the implantation of the elephant trunk. Then the aortic root and the vascular graft anastomosis were performed to reconstruct the ascending aorta. At last, the left subclavian artery and innominate artery were anastomosed to the branch of the vascular graft under the beating heart. ResultAll 38 operations were successful. The mean hypothermic circulatory time of the whole group was 18.8±4.2 min, the time of ascending aorta blocking was 86.1±14.2 min, the time of cardiopulmonary bypass was 178.4±71.4 min, the time of postoperative awakening was 4.7±2.0 h, the time of assisted mechanical ventilator was 38.7±19.9 h. One patient died because of multiple organ dysfunction syndrome (MODS), 3 patients accepted the hemodialysis, 6 patients suffered from transient neurological dysfunction, 1 patient suffered from paraparesis. There was no further complication during the follow-up of 1-3 months. ConclusionThe modified total aortic arch replacement can shorten the circulatory arrest time, cardiac arrest time and cardiopulmonary time, provide effective organ perfusion, and reduce the neurological complication and visceral damage.
