Peripheral nerve injury therapy in the clinic remains less than satisfactory. The gold standard of treatment for long peripheral nerve defects is autologous nerve grafts; however, numerous clinical complications are associated with this treatment. As tissue engineering has developed, tissue-engineered nerve grafts (TENGs) have shown potential applications as alternatives to autologous nerve grafts. To verify the important role of the biomimetic pathway of fascicle design in TENGs, we designed an animal model to study the role of the precise matching of fascicles in the effectiveness of nerve function recovery...

PURPOSE OF REVIEW: With expanding experience and success of liver transplantation, increasing numbers of elderly candidates await and undergo liver transplantation. There is accumulating evidence that graft survival and mortality does not appear to differ significantly between the young and carefully selected elderly liver transplantation recipients. Although existing evidence suggests that psychosocial factors impact outcomes after liver transplantation in general, no such information is available specifically for elderly (age ≥65 years) liver transplantation recipients...

Background The incidence of knee ligament injury is increasing and represents a significant cost to healthcare providers. Current interventions include tissue grafts, suture repair and non-surgical management. These techniques have demonstrated good patient outcomes but have been associated graft rejection, infection, long term immobilization and reduced joint function. The limitations of traditional management strategies have prompted research into tissue engineering of knee ligaments. Objective This paper aims to evaluate whether tissue engineering of knee ligaments offers a viable alternative in the clinical management of knee ligament injuries...

Chronic expanding hematoma (CEH) after coronary artery bypass grafting (CABG) is extremely rare. We reported a case of successful surgical repair of CEH through lower partial sternotomy approach. The patient was a 73-year-old man who underwent CABG. Fifteen years after the operation, he was admitted to referral hospital because of dyspnea on exertion. Echocardiography and computed tomography revealed a giant intrapericardial mass, which was pressing on the inferior wall of the ventricle. To avoid injury of the aorta and the patent bypass graft in the reentry of the chest, we selected lower partial sternotomy approach...

We evaluated 71 patients treated with allogeneic hematopoietic cell transplantation (allo-HCT) for multiple myeloma (MM). Forty-three patients (61%) received allo-HCT after the first line of therapy. Fifty-eight patients (82%) had chemosensitive disease at the time of allo-HCT. A HLA-matched related or unrelated donor was available for 68 patients (96%). Non-myeloablative or reduced-intensity conditioning regimen and peripheral blood hematopoietic cells as a graft source were used in most patients. The cumulative incidence of grade II-IV acute GVHD at day +100 and chronic GVHD at 5 years was 13% (95% CI 7-23%) and 35% (95% CI 24-46), respectively...
