  • 低旋转点腓肠神经营养血管皮瓣修复前足软组织缺损

    目的 总结采用低旋转点腓肠神经营养血管皮瓣修复前足软组织缺损的疗效。 方法2007年3月-2011年10月,收治前足软组织缺损 13 例。男12例,女1例;年龄 19~45岁,平均30.7岁。左足 9例,右足 4例。致伤原因:交通事故伤3例,重物砸伤5例,穿刺伤5例。其中一期急诊修复2例,二期修复11例。软组织缺损范围9 cm × 8 cm~17 cm × 14 cm。采用大小为10 cm × 9 cm~19 cm × 16 cm的低旋转点腓肠神经营养血管皮瓣修复创面;供区直接拉拢缝合或游离植皮修复。 结果术后1例皮瓣出现局部张力性水疱,2例发生皮瓣肿胀,经对症处理后均成活;其余皮瓣均顺利成活,创面Ⅰ期愈合。供区植皮均顺利成活,切口Ⅰ期愈合。13例均获随访,随访时间8~24个月,平均14个月。皮瓣质地柔软,外形稍臃肿,不影响穿鞋及行走。皮瓣感觉均不同程度恢复,末次随访时皮瓣两点辨别觉为8~13 mm,平均11 mm。 结论低旋转点腓肠神经营养血管皮瓣手术切取简便,成活率高,是修复前足软组织缺损的有效方法之一。

  • Attaching importance and practicing integrated management of chronic kidney disease

    Chronic kidney diease has a high incidence. It is a major disease that seriously endangers human health. The integrated management of chronic kidney disease, through etiological treatment of chronic kidney disease, delaying the deterioration of renal function, and the combination of hemodialysis, peritoneal dialysis and kidney transplantation for end-stage kidney disease treatment, is a scientific and effective full-course management of chronic kidney disease. The integrated management of chronic kidney disease is the key to reduce the mortality and disability rates. At the same time, it is a more important and far-reaching task to emphasize early popularization of science, screening, prevention and intervention to reduce the incidence of kidney disease.

  • Effectiveness of mini locking plate combined with Kirschner wire in treatment of comminuted Jones fracture

    ObjectiveTo summarize the effectiveness of mini locking plate combined with Kirschner wire in treatment of comminuted Jones fracture.MethodsBetween January 2011 and October 2016, 25 cases with comminuted Jones fracture were treated with mini locking plate combined with Kirschner wire. There were 9 males and 16 females with an average age of 31.4 years (range, 16-66 years). The fractures located on the left side in 11 cases and on the right side in 14 cases. The causes of injury included spraining in 21 cases, falling down in 3 cases, and bruise in 1 case. The bone fragment of all cases was more than 3 pieces. The fracture line was mostly Y-shape or T-shape. Twelve of them were combined with other fractures. The time from injury to operation was 1-9 days (mean, 5 days). The mini locking plate and Kirschner wire were removed at 9-12 months postoperatively. At 12 months postoperatively, the pain was evaluated by the visual analogue scale (VAS) score, and the function by the American Orthopaedic Foot & Ankle Society (AOFAS) score.ResultsAll incisions healed by first intention. All cases were followed up 12-36 months with an average of 21.7 months. Fracture union was observed in all patients without complications such as nonunion, delayed union, and malunion. The fracture union time was 8-12 weeks (mean, 9.4 weeks). At 12 months postoperatively, the VAS score was 1.15±0.87; the AOFAS score was 89.45±6.24, and the results were excellent in 14 cases, good in 9 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 92%.ConclusionThe procedure of mini locking plate combined with Kirschner wire for comminuted Jones fracture has such advantages as convenient operation, more rigid fixation, high rate of fracture healing, and good functional recovery in foot.

  • Hemodynamic study of personalized Stanford type B aortic dissection based on computational fluid dynamics

    Objective To establish a personalized Stanford type B aortic dissection numerical simulation model, and using computational fluid dynamics (CFD) numerical simulation to obtain the hemodynamic behavior and law of the type B aortic dissection at different stages of development. Methods Based on the theory of three-dimensional model reconstruction, we used CT images of a patient with type B aortic dissection in the Xiamen Cardiovascular Hospital of Xiamen University, relevant medical image processing software to reconstruct a personalized aortic three-dimensional model, and CFD to reconstruct the model which was simulated in fluid mechanics. Results The three-dimensional reconstruction model could intuitively observe the changing trend of the false cavity at different stages of the dissection development. Through fluid mechanics simulation, the blood flow rate, pressure, wall shear stress, vascular wall Von Mises stress and other parameters at different stages of the dissection development were obtained. Conclusion The hemodynamic behavior and law of relevant parameters in the development stage of aortic dissection are analyzed. The combination of the values of relevant parameters and clinical medical detection and diagnosis can well predict the development of the disease, and finally provide more theories and methods for the scientific diagnosis of aortic dissection.
