目的 分析总结严重挤压伤导致四肢创伤性截肢各种生化指标的动态变化及对临床中治疗的指导意义。 方法 2000年3月－2011年3月对23例由于严重挤压导致创伤性截肢的患者各项生化指标检测结果进行实时监控，根据监控结果及时调整治疗方案。 结果 伤后患者电解质，血、尿肌红蛋白，尿比重，尿pH值，血肌酸激酶、肌酸激酶同工酶、羟丁酸脱氢酶、白蛋白、血红蛋白、血小板等指标均有明显改变，据此作为救治的依据进行精细化治疗。术后随访7个月～10年，23例患者均得到康复，肾功能良好。 结论 对于严重挤压伤导致四肢创伤性截肢的各种生化指标实时监控并同步制定精细化治疗，才能确保患者成功救治并得以康复。
目的探讨复杂胆管疾病胆囊切除术的处理方法，减少医源性胆管损伤的发生率。方法回顾性分析2000年1月至2005年1月收治的160例困难胆囊切除术患者的资料，对其处理方法进行总结。结果结合术中B超和胆管造影检查，顺逆结合，解剖、明确三管关系后切除胆囊132例，取出结石行胆囊部分切除术26例，行肝叶楔形切除2例，其中行胆总管修补、T管引流7例，胆肠RouxenY吻合5例，结扎副肝管4例。结论仔细解剖、辨清三管关系是预防困难胆囊切除术并发症的主要措施。
Objective To evaluate the coronary artery ostium obstruction caused by the commissure of transcatheter heart valve (THV) with the markers on THV under X-ray, which was identified by observing the position relationship between the commissure of THV and the coronary artery ostium from analyzing aortic root computed tomographic angiography (CTA) images after transcatheter aortic valve replacement (TAVR). Methods A retrospective analysis was performed on 25 patients undergoing TAVR who were checked with electrocardiographically gated CTA for the aortic root after the TAVR procedure between January 2020 and December 2021 in General Hospital of Northern Theater Command. The images of THV with the lowest position of non-coronary sinus and the right anterior oblique and caudal in most cases were observed when the THVs were deployed. The position relationships of the three markers on the THV after valve release were recorded, which were divided into three conditions, namely the three markers being averagely distributed, the middle marker being close to left, and the middle marker being close to right. Postoperative CTA images of the patients were analyzed. The angle between the commissure of THV and the coronary artery ostium was measured, and the angles in each group were presented as medium (lower quartile, upper quartile). Results A total of 17 patients were finally included. The angles between the commissure of THV and the left coronary artery ostium were 19.0 (16.0, 31.0)°, 36.0 (15.0, 44.0)°, and 3.0 (3.0, 5.0)° in the markers averagely distributed group (n=7), the middle marker close to left group (n=6), and the middle marker close to right group (n=4), respectively, which were significantly different (P=0.033). The angles between the commissure of THV and the right coronary artery ostium were 43.0 (25.0, 51.0)°, 47.0 (41.0, 57.0)°, and 13.0 (7.5, 21.0)° in the markers averagely distributed group, the middle marker close to left group, and the middle marker close to right group, respectively, which were significantly different (P=0.017). There was significant difference in the obstruction degrees of left coronary artery ostium by the commissure of THV (P=0.008), and no significant difference in the obstruction degrees of right coronary artery ostium (P=0.062). When the middle marker was close to right, there was no more than moderately obstruction on the right coronary artery ostium and no any obstruction on the left coronary artery ostium. When the middle marker was close to left, the obstruction rate of the left coronary artery ostium with more than moderate degree was 4/6 (66.7%) and it was 6/6 (100.0%) for the right coronary artery ostium. Conclusions The degree of coronary artery ostium obstruction by the commissure of THV can be accurately evaluated by using markers on THV. Among them, when the middle marker is close to right, the commissures of THV are least likely to block the coronary artery ostium.
Lumbar disc herniation (LDH) is one of the most important causes of back and leg pain, which seriously affects the quality of life of patients. As the first-line treatment for LDH, non-operative treatment can relieve 80% to 90% of symptoms among the patients with LDH. This guideline followed Guidelines for the Formulation/Revision of Clinical Treatment Guidelines in China (2022 edition) and WHO handbook for guideline development (2014 edition) to set up guideline working group. This guideline identified fourteen clinical questions through the literature review and clinical experts’ consensus. We drafted the recommendations after systematically searching and evaluating the evidence; delphi method was adopted for expert consensus on the preliminary recommendations, finally, 19 recommendations were made to guide non-operative treatments for LDH. This guideline can provide guidance for the clinical practice of Chinese and western orthopedics practitioners.
