Objective To explore the effectiveness of treating postoperative pain of mixed hemorrhoid by embedding needles in Erbai (二白EX-UE 2) and find possible ways for relieving postoperative pain of mixed hemorrhoids. Methods press needle (SEIRIN pyonexes) were embedded in EX-UE 2 of patients with postoperative pain of mixed hemorrhoid, once a day and totally 7 treatments. Visual analogue scale (VAS) values were adopted for evaluation. Results Complete remission of clinical pain was observed in 34 cases, accounting for 50.00%; significantly effective in 19 cases, accounting for 27.94%; effective in 13 cases, accounting for 19.12%; and ineffective in 2 cases, accounting for 2.94%; the total effective rate was 97.06%. Conclusion The therapy of treating postoperative pain of mixed hemorrhoid by embedding press needle in EX-UE2 is effectively satisfactory. 展开更多

Objective: To discuss the pathological characteristics of cervical spinal fracture complicating ankylosing spondylitis (AS) and the effect of combined anterior and posterior operation. Methods: Eighteen AS patients with traumatic cervical fracture-dislocation were treated operatively from January 2000 to January 2006. The symptom duration of AS was 14.5 years on average. Three cases had undergone osteotomy in lumbar spine. There were 4 cases of Grade A, 3 cases of Grade B, 9 cases of Grade C and 2 cases of Grade D according to Frankel's score. There were 15 cases of Grade III dislocation and 3 cases of Grade II. All patients underwent surgical procedures by combined anterior and posterior approach. Results: There were 4 anterior-posterior procedures, 8 anterior-posterior-anterior procedures and 6 posterior-anterior procedures. Seven patients had one stage operation and 11 cases underwent two stage surgeries. There was certain extent of neurological improvement in 14 incomplete paraplegic patients, but no improvement in 4 complete paraplegic patients. The follow-up period was 21.2 months on average and the time for bone fusion was 3.6 months. There were 4 complications during operation and a longterm complication in follow-up. Conclusions: The study suggests that anterior combined with posterior approach makes the spine stable and relieves the pressure immediately. It is a reasonable surgical strategy for treatment of cervical spinal fracture-dislocation with AS. 展开更多

This paper introduces a new concept of 4PL, which is a contractor of the closed-loop supply chain coordination based on the division of community and the outsourcing development. The concept enriches the connotation of 4PL and broadens the thought for 4PL development. Secondly, according to the characteristics of the closed-loop supply chain in the different duration of the collaborative relationship and the dynamic characteristics of the closed-loop supply chaini we apply the fractal theory to establish a fractal system of 4PL coordinating closed-loop supply chain and propose different strategies for 4PL coordinating with different types of closed-loop supply chains in the various links of the system. Moreover, some strategic and proactive thinking are provided for 4PL's practices. Then based on the exergoeconomics theory, the closed-loop supply chain is regarded as a huge energy system with the new view, and the sustainability of the closed-loop supply chain system is discussed under the circumstance of exergoeconomics, and then the metric about “system negative environment effect” is introduced to measure the closed-loop supply chain system performance in the point of energy, a case study illustrates our conclusions. 展开更多
