Objective To estimate the effects of risk factors on early survuval (90 days) after lung transplantation for idiopathic pulmonary fibrosis (IPF).Method We reviewed 49 cases of lung tansplant male patients which suffered from IPF.Two groups were set up according to the early survival.The early outcomes (90 days) were compared between two groups by multiple logistic regression analysis.Result The early survival rate was 81.6%.Multivariate analysis confirmed that mean pulmonary artery pressure and bilateral lung transplantation (BLTx) were risk factors after adjustment for potential confounders.Recipients' age,lung volume reduction on donors,and use of extracorporeal membrane oxygenation (ECMO) were not risk factors for early mortality.Conclusion The increased pulmonary artery pressure and BLTx are risk factors for death after lung transplantation in IPF.Preoperative evaluation of mean pulmonary artery pressure and choosing suitable operative method could improve the surgical outcomes of lung transplantation.

Objective:To evaluate the arthroscopy-assisted reduction and internal fixation (ARIF) via the traditional anterolateral approach for the treatment of posterolateral tibial plateau fractures (PTPF).Methods:A retrospective study was conducted of the 79 patients with PTPF who had been treated from March 2014 to February 2020 at Department of Articular Surgery, Linyi Central Hospital. They were 37 males and 42 females, aged from 17 to 71 years (average, 46.0 years). According to treatment methods, they were assigned into an ARIF group (37 cases) and a control group (42 cases). The ARIF group was treated by ARIF via the traditional anterolateral approach and the ARIF varied according to the extents of articular collapse and split and displacement of fracture fragments. The control group was treated by traditional reduction and internal plate fixation of the proximal tibia. The 2 groups were compared in terms of operation time, blood loss, iliac bone grafting, hospitalization time, follow-up time, Hospital for Special Surgery (HSS) score, maximum flexion and extension, fracture healing time, Rassmussen functional and anatomical scores, visual analogue scale (VAS) pain score and complications.Results:There was no statistically significant difference in the general data between the 2 groups, showing comparability ( P>0.05). All patients were followed up for 6 to 18 months (average, 11.4 months). The operation time [(48.9±8.2) min], blood loss [(73.1±20.8) mL], hospitalization time [(9.3±2.5) d], and fracture healing time [(12.5±1.8) weeks] in the ARIF group were all significantly less than those in the control group [(55.2±9.9) min, (100.8±30.3) mL, (11.8±2.8) d and (15.1±2.1) weeks] while the HSS score [(93.5±4.6) points], maximum flexion angle (107.8°±10.4°) and Rassmussen functional score [(27.1±1.8) points] in the ARIF group were significantly higher than those in the control group [(88.4±7.4) points, 100.4°±10.0° and (26.1±2.4) points] (all P<0.05). There was no significant difference between the 2 groups in iliac bone grafting, follow-up time, maximum extension angle, Rassmussen anatomical score, VAS score, or rate of complications (all P>0.05). Conclusions:Compared with traditional surgery, ARIF which varies with the extents of articular collapse and split and displacement of fracture fragments may lead to shorter operation time, reduced surgical trauma and more accurate reduction of the articular surface. Therefore, it can be an additional choice in the treatment of PTPF.

Objective To explore the efficacy and prognosis of lung transplantation from donors combined with pulmonary contusion on the treatment of patients with end-stage lung disease. Methods Clinical data of 73 cases of donors and recipients were collected. The donors and recipients were divided into contusion group (23 cases of donors and recipients, with a maximum diameter of contusion in 5-8 cm) and standard group (50 cases of donors and recipients) depending on combined pulmonary contusion. Major clinical indicators [postoperative oxygenation index, duration of mechanical ventilation and chest tube drainage and incidence of primary graft dysfunction (PGD)] and prognosis of the recipients in both groups were compared. Results The recipients in both groups presented no significant difference in postoperative oxygenation index, duration of mechanical ventilation and chest tube drainage and incidence of PGD (all P>0.05). The postoperative 1-year survival of the recipients in standard group and contusion group was 74% and 83%, which presented no statistically significant difference (P>0.05). Conclusions The efficacy and prognosis of lung transplantation from donors combined with pulmonary contusion (with a maximum diameter of 5-8 cm) are comparable to those of lung transplantation from standard donors.
