Objective:To compare the effects of 5 prone ventilation positions in patients with acute respiratory distress syndrome (ARDS) with network Meta-analysis.Methods:The randomized controlled trials on various prone ventilation positions in patients with ARDS were retrieved from Cochrane Library, EMbase, CINAHL, PubMed, Web of Science, SinoMed, CNKI, Chinese Medical Association Guideline Database, Wanfang Data, China Biology Medicine disc, VIP Information and Chinese Clinical Trial Registry from their inception to December 31, 2023. Literature screening, quality assessment and data extraction were done following the inclusion and exclusion criteria. Network Meta-analysis of outcome indicators was done using Stata 18.0.Results:A total of 19 articles, covering 1 284 patients and 5 prone ventilation positions (0°, 10°, 30°, 25° and 45°) were included. Cochrane risk assessment results showed that 15 articles were grade B and 4 articles were grade C. In direct comparisons, heterogeneity was acceptable ( I2≤50% and P≥0.1). In network analysis, the global and local consistency test result showed good consistency ( P>0.05). Network Meta-analysis result showed that the incidences of pressure injury in patients with 10°, 25°, 30° and 45° prone ventilation were significantly lower than that in patients with 0° prone ventilation, the incidence of pressure injury in patients with 25° prone ventilation was significantly lower than that in patients with 10° prone ventilation, and there were statistical differences ( P<0.05); the oxygenation index in patients with 25° prone ventilation was significantly better than that in patients with 0°, 30° and 45° prone ventilation, and there was statistical difference ( P<0.05). Conclusions:The 25° prone ventilation can both effectively improve oxygenation and maximally reduce the incidence of pressure injury in patients with ARDS.

Objective To analyze the correlation between the lung allocation score (LAS) and the risk of early death and complications in patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 275 patients with IPF were retrospectively analyzed. The correlation between LAS and the risk of early death in IPF patients after lung transplantation and the correlation between LAS and complications at postoperative 1 year was assessed by univariate and multivariate Cox regression analyses. Results Among 275 recipients, 62, 83, 95 and 108 cases died within postoperative 30, 90, 180 and 365 d, respectively. LAS was correlated with 30-, 90-, 180- and 365-d fatality of IPF patients (all P<0.05), whereas it was not correlated with the incidence of primary graft dysfunction (PGD) and acute kidney injury (AKI) at 365 d after lung transplantation (both P>0.05). Conclusions LAS is correlated with the risk of early death of IPF patients after lung transplantation. While, it is not correlated the incidence of PGD and AKI early after lung transplantation. Special attention should be paid to the effect of comprehensive factors upon PGD and AKI.

Objective To explore the establishment of a prognostic model based on machine learning algorithm to predict primary graft dysfunction(PGD)in patients with idiopathic pulmonary fibrosis(IPF)after lung transplantation.Methods Clinical data of 226 IPF patients who underwent lung transplantation were retrospectively analyzed.All patients were randomly divided into the training and test sets at a ratio of 7∶3.Using regularized logistic regression,random forest,support vector machine and artificial neural network,the prognostic model was established through variable screening,model establishment and model optimization.The performance of this prognostic model was assessed by the area under the receiver operating characteristic curve(AUC),positive predictive value,negative predictive value and accuracy.Results Sixteen key features were selected for model establishment.The AUC of the four prognostic models all exceeded 0.7.DeLong and McNemar tests found no significant difference in the performance among different models(both P＞0.05).Conclusions Based on four machine learning algorithms,the prognostic model for grade 3 PGD after lung transplantation is preliminarily established.The overall prediction performance of each model is similar,which may predict the risk of grade 3 PGD in IPF patients after lung transplantation.

Objective:To compare the effect of extracorporeal membrane oxygenation(ECMO)on pulmonary transplantation(LTx)in patients with idiopathic pulmonary fibrosis(IPF)complicated with pulmonary hypertension(PH).Methods:From January 2017 to December 2020, clinical data were retrospectively reviewed for 112 IPF patients complicated with PH undergoing LTx assisted by venous ECMO(VV-ECMO group, n=68)or venous arterial ECMO(VA-ECMO group, n=44). Gender, age, mechanical ventilation time, oxygenation index, cold ischemic time, preoperative gender, age, smoking history, PO 2, PCO 2, PH degree, NYHA cardiac function grade, right cardiac function, ejection fraction(EF)and complications(hypertension & diabetes)of two groups were compared. Intraoperative approach, operative duration, ECMO transfer time, blood loss, blood transfusion, urine volume, postoperative blood transfusion, mechanical ventilation time, ICU stay time, re-thoracotomy, pulmonary infection, primary graft dysfunction(PGD)and renal insufficiency were recorded. And the effects of two different diversion modes on early postoperative complications and short-term outcomes of LTx were further analyzed by multiple factors. Cox proportional risk model was employed for comparing VV-ECMO and VA-ECMO flow patterns with factors related to recipient survival after transplantation. Results:The preoperative PO 2 of 58.3(51.3, 72.0)mmHg was significantly lower in VV-ECMO bypass group than that of 73.2(63.3, 96.8)mmHg in VA-ECMO group and the difference was statistically significant( P<0.006). Compared with VV-ECMO group, 24(54.5%), 15(34.1%)and 22(50.0%)had NYHA class Ⅲ, severe PH and preoperative right heart enlargement in VA-ECMO group respectively and the differences were statistically significant compared with 17(25.0%), 6(8.8%)and 16(23.5%)in VV-ECMO group( P<0.05 for all). No significant inter-group differences existed in postoperative PGD, postoperative mechanical ventilation time(≥3 d), pulmonary infection, postoperative thoracotomy ratio, postoperative renal insufficiency, ICU stay, hospital stay and other aspects( P>0.05). And 6-month postoperative survival rates of VV-ECMO and VA-ECMO groups were 80.9% and 61.4%, respectively and no significant inter-group difference existed in short-term survival rate(6 months)after adjustment by multivariate Cox regression model( P>0.05). Multivariate statistics indicated that the risk of delayed postoperative withdrawal was 14.452-fold higher in VV-ECMO group than in VA-ECMO group and the inter-group difference was statistically significant(95% CI: 2.448-85.323, P=0.03). Conclusions:No differences exist in postoperative complications or short-term survival rate between IPF recipients with mild PH on VV-ECMO mode and IPF recipients with severe PH on VA-ECMO mode. VV-ECMO flow reversal can delay the transplant back-off time.

Objective:To explore the early prognosis on patient of idiopathic pulmonary fibrosis (IPF) combined with different degrees of pulmonary arterial hypertension (PAH) undertake lung transplantation (LTx).Methods:From January 2017 to December 2020, the clinical data of 134 patients with IPF who underwent LTx in Wuxi People's Hospital were analyzed retrospectively. According to the average pulmonary artery pressure detected by right cardiac catheter before operation, the patients were divided into mild PAH group (63 cases), moderate PAH group (47 cases) and severe PAH group (24 cases). The donor data and the recipient's preoperative, intraoperative and postoperative data were collected; the postoperative survival curve to analyze early survival among the three patient groups.Results:With the increase of pulmonary artery pressure, the rate of abnormal right ventricular function increased, the end diastolic diameter of left ventricle decreased before operation, and the rate of using veno-arterial extracorporeal membrane oxygenation (V-A ECMO) increased during the surgery ( P<0.05). Multivariate analysis found that combined severe PAH had significant effects on primary graft dysfunction (Primary graft dysfunction, PGD), retracheal intubation or tracheotomy, hypovolemic shock within 72 h, and 6-month survival after LTx. The survival surve showed that 30-day survival rates of patients with IPF complicated with mild, moderate and severe PAH were 85.7%, 80.8% and 66.7% respectively, and the 6-month survival rates were 80.9%, 74.0% and 62.2%, respectively. Conclusion:Patient of IPF combined with different degrees of PAH had a significant impact on cardiac function and intraoperative ECMO selection of LTx, and severe PAH could significantly reduce the early survival rate after LTx.

Hippo signaling pathway plays a significant role in the development of colorectal cancer,and acts as an important regulatory pathway which regulates cell proliferation and cell differentiation.Multiple proteins and genes in Hippo signaling pathway,especially the downstream YAP protein,play important roles in the occurrence,metastasis,drug resistance and recurrence of colorectal cancer.YAP and other related genes can be used as targeted markers for predicting drug resistance to colorectal cancer.Hippo signaling pathway gene network can be used as targeted therapy or combination therapy,thus providing new ideas for the treatment of colorectal cancer.
