Chinese Journal of Orthopaedics 2000;0(11):-
Objective To investigate the clinical value of spiral computerized tomographic shaded surface display (SSD) and multiplanar(MPR) imaging of complex shoulder fractures. Methods Twenty four cases of complex shoulder fractures including 16 cases with displaced proximal humeral fractures and 8 cases with displaced fractures of glenoid fossa were examined preoperatively with X ray, 15 cases of them were examined with SSD and MPR. On the basis of X ray or SSD and MPR of SCT all fractures were classified with Neer and modified Ideberg system; the true rate of fracture classification by use of two methods was compared with each other. Results Evidenced by intraperative observation, 10 of 16 displaced proximal humeral fractures cases were Neer three part fractures, 6 were four part fractures cases. Among the 8 cases of glenoid fossa fractures, there were 2 cases of type Ⅲ, 3 cases of type Ⅳ and 3 cases of type Ⅴ. The true rate of SSD and MPR of SCT is 93.3%(14/15) while X rays is 41.7%(10/24); there was significant difference between two methods (Fishers exact test, P=0.02). All SSD and MPR of SCT play an important role in the treatment of complex shoulder fractures. Conclusion SSD and MPR of SCT is able to clearly display complex shoulder fractures three dimensionally. It is helpful to correctly classify the fractures, select appropriate surgical approach, prepare surgical instruments and understand the complexity of the fractures.

Objective To discuss the feasibility of the lung transplantation as an effective treatment for end-stage pulmonary diseases domestically and to compare the major issues involving the practice of lung transplantation domestically and overseas.Methods After the foundation of group of lung transplantation in May 2002, lung transplantation models of porcine were set up. From September 2002 to April 2005, in the 18 cases undergoing lung transplantation, there were subjected to single-lung transplantion (SLT, 83.3%) and 3 bilateral sequential single lung transplants without CPB (DSSLT, 16.7%). Indications for SLT (n=15) included emphysema (n=9), pulmonary fibrosis (n=3), pneumosilicosis (n=1), lymphangioleiomyomatosis (n=1) and ventricular septal defect (VSD) induced Eisenmenger's syndrome (n=1); for DSSLT (n=3) bronchiectasis (n=1) and pulmonary emphysema (n=2). Among the 15 SLTs, there were 9 cases of left SLT and 6 right SLT. Among them, 2 cases shared one same donor's lung block, one case received contralateral lung transplantation―a left donor lung implanted in the recipient’s right thorax, and one case simultaneous right SLT and VSD repair. Results In hospital mortality (HM) was 3/18 ( 16.7%). Among SLTs, early death was due to severe rejection on the 30th postoperative day in one patient and acute rejection on the 15th postoperative day in other patients, and another patient died due to pulmonary vein embolism on the 36th day. There were 3 and 2 patients with the survival time longer than 1 and 2 years respectively. The median overall survival was 10 (2 to 32) months. Conclusions Our LT program shows similar results to those reported by the International Society for Heart and Lung Transplantation for developed countries. The key of successful operation depends on the establishment of group of lung transplantation and cooperation of multi-department. Ischemic-reperfusion injury, acute-rejection and infection are the major reasons of deaths shortly after the operations.

Objective To investigate the effect of hypoxia-inducible factor-1α expression (HIF-1α) on toll-like receptor 4 (TLR4) signaling pathway-mediated rat lung ischemia-reperfusion injury (LIRI).Method Forty-five S-D rats were randomly divided into Sham group,LIRI group,LIRI+ TLR4-activated group,LIRI+ TLR4-inhibited group,LIRI + ASK1-inhibited group,LIRI + p38-inhibited group,and LIRI + HIF-1α-inhibited group.The interaction between TLR4 signaling pathway [including TLR4,myeloid differentiation factor 88 (MyD88),TIR-domain-containing adapter-inducing interferon-βTIR-domain-containing adapter-inducing interferon-β (TRIF),Apoptosis signal-regulating kinase 1 (ASK1) and p38] and HIF-1α and the role of TLR4-dependent HIF-1α in LIRI in vivo were analyzed.Result In LIRI,HIF-1α accumulation was induced in a TLR4-dependent fashion,and MyD88,but not TRIF,and activation of ASK1 and P38 were found to be critical for TLR4-mediated HIF-1α accumulation.HIF-1α protein played a critical role in TLR4-mediated lung injury of LIRI.HIF-1α up-regulated TLR4 expression in LIRI in a positive feedback manner.Conclusion We identify that HIF-1α has a damaging effect on TLR4 signaling pathway-mediated LIRI and TLR4-HIF-1 may synergistically involved in the development of LIRI.Therefore we suggest that the interaction between them may represent a novel therapeutic target for the development of novel target-based therapies of LIRI.

Objective To evaluate the operative technique, perioperative management and outcomes of bilateral lung transplantation for idiopathic pulmonary artery hypertension. Methods There were 2 cases of idiopathic pulmonary hypertension subject to bilateral sequential lung transplantation with ECMO support (16, 17 years old, respectively). The pulmonary artery pressure was 10/70 and 148/72 mm Hg respectively. The heart function was NYHA Ⅳ, the operative procedure was right lung first, then left lung, and the cold ischemia time was 230 min/430 min and 185 min/300 min respectively. The ECMO support time was 550 min and 450 min respectively. The blood loss during the operation was 3000 and 1200 ml, respectively. Resuits The ECMO was withdrawn 16 and 13 h postoperation respectively. There was unstable hemadynamics and acute left heart failure on the 3rd and 4th day after the operation. The patients were treated with ventilate support and tracheotomy on 3rd and 6th day respectively. Additionally, the patients were given cardiotonic, dieresis and the ventilation was withdrawn on 33rd and 12th day after the operation respectively. They were discharged from the hospital on 93rd and 32nd day after the operation. The heart function both reached NYHA I, two cases were followed up for 25 and 10 months respectively.Both of them had an excellent quality life. Conclusion Bilateral lung transplantation is effective for end-stage idiopathic pulmonary artery hypertension even with slight right ventricular dysfunction with satisfactory short-term outcome. A limited operative time, an ECMO support for heart and lung during the peri-operative period and a perfect management for the left ventricular dysfunction after surgery are key roles for the success. Closed follow-up and surveillance are needed for long-term outcomes.
