It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal individuals, but the relationship between lower limb amputation and the episodes of cardiovascular disease has not been studied from the perspective of hemodynamics. In this paper, numerical simulation was used to study the effects of amputation on aortic hemodynamics by changing peripheral impedance and capacitance. The final results showed that after amputation, the aortic blood pressure increased, the time averaged wall shear stress of the infrarenal abdominal aorta decreased and the oscillatory shear index of the left and right sides was asymmetrically distributed, while the time averaged wall shear stress of the iliac artery decreased and the oscillatory shear index increased. The changes above were more significant with the increase of amputation level, which will result in a higher incidence of atherosclerosis and abdominal aortic aneurysm. These findings preliminarily revealed the influence of lower limb amputation on the occurrence of cardiovascular diseases, and provided theoretical guidance for the design of rehabilitation training and the optimization of cardiovascular diseases treatment.

Objective To investigate the amputation-related pain and quality of life (QoL) between the amputees with transfemoral amputation (TFA) and transtibial amputation (TTA) 10 years after the Wenchuan earthquake, and compare the effects of two different amputation level on the long-term functional rehabilitation of amputees. Methods A total of 305 amputees from Center of Comprehensive Service of Disabled of Deyang for the disabled 10 years after the Wenchuan earthquake were selected for cross-sectional study from February to June 2018. Through face-to-face interview, the basic information of amputees was collected and the evaluation of Prosthetic Evaluation Questionnaire (PEQ) was completed. The amputees were divided into TFA group and TTA group according to the amputation level. Results A total of 53 amputees were included, including 27 in the TFA group and 26 in the TTA group. The PEQ scores showed that the prevalences of phantom limb sensation (96.3% vs. 65.4%; χ2=6.372, P=0.012) and phantom limb pain (92.6% vs. 69.2%; P=0.039) in the TFA group were significantly higher than those in the TTA group. There was no significant difference with regard to the intensity of amputation-related pain between the victims with TFA and TTA (P>0.05). However, the TFA group were more bothered by phantom limb sensation than the TTA group (52.9±24.1 vs. 35.9±26.7; t=2.108, P=0.042), there was no significant difference in other indexes (P>0.05). There was no significant difference in QoL between the TFA and TTA groups (P>0.05). Conclusions The phantom limb sensation, phantom limb pain, residual limb pain, non-amputated limb pain and back pain are still prevalent among the victims with TFA and TTA 10 years after the Wenchuan earthquake. The higher amputation level is associated with increased prevalence of phantom limb sensation and phantom limb pain, as well as more bothersomeness of phantom limb sensation. The amputation level appeares to have no impact on the long-term QoL.
Since October 1975, 35 patients with congenital constriction bands were treated. Follow-up for 10 months to 14 years showed that the results of correction were satisfactory except 1 patient died from other disease. The etiolology, the concurrent deformities and the method of treatment were discussed.
目的:探讨5·12汶川地震中因外伤而截肢的患者产生各种心理反应的原因和护理对策,以采用有效的护理措施。方法:以我院收治的地震伤致截肢患者23例为研究对象,采用面对面与患者及家属交谈、观察患者的心理行为、转院后随访等形式,用应对方式量表对心理护理进行评分及分析,并针对性采取心理护理。结果:截肢患者在治疗前后出现自我概念改变、不确定感、社会适应力改变等正性和负性心理效应;经过心理护理,能消除心理障碍,均获得较好的治疗效果。结论:正确的心理分析和针对性心理护理有利于患者的心理调适,产生正性心理效应,积极应对疾病。
Objective To investigate the characteristics of patients with crush injury in Wenchuan earthquake and the corresponding operational methods. Methods From May 12th 2008 to June 18th 2008, 202 patients with crush injury of soft tissue were treated, including 110 males and 92 females. Twenty-five patients aged 19 months to 16 years, 129 patients aged 17-60 years and 48 patients aged above 61 years. The crushed time was 30 minutes to 154 hours. Sixty cases of openinjuries were treated by debridement and dressing or suture; 16 cases of damaged extremities (18 l imbs) and 6 cases of acute renal failure due to crush syndrome (8 l imbs) received amputation; 32 cases of interfascial space syndrome crisis (42 l imbs) were treated by fascia cavity decompression; 15 cases received the resection of necrotic muscle for 31 times; and 9 cases received continuous renal replacement therapy (CRRT). Results All the wounds healed except 2 cases which died from intestinal bleeding and intracranial hemorrhage during the treatment of CRRT. Two cases were discharged 8 months after treatment, while the other 198 cases recovered and were discharged 15-120 days after treatment. The average hospital ization time was 53 days. Twenty-two cases (26 l imbs) were fixed with artificial l imbs 3-6 months after amputation and achieved good functional outcome. Conclusion The treatment principle of crush injury is “be active to decompress and be prudent to amputate”, the hardening muscle and the increasing level of creatine kinase and blood potassium are the golden indicators of fascia cavity decompression. Decompression at an earl ier period is preferred when there is a dilemma to choose, and open amputation should be performed when the necrotic muscle is hard to clear or the necrosis boundary is not distinct.
