Objective To systematically review the value of rapid on-site evaluation (ROSE) for diagnosing pulmonary and mediastinal lesions with endobronchial ultrasound (EBUS). Methods PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang, and VIP databases were searched by computer to collect the studies of ROSE and EBUS in the diagnosis of pulmonary and mediastinal lesions from inception to August 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Meta-analysis was implemented by RevMan 5.4 and Stata 12.0 software. Results A total of 15 studies (9 retrospective studies and 6 prospective studies) with 3 577 patients were included. The meta-analysis results of main outcomes showed that the adequacy of the sample (RD=0.10, 95%CI 0.05 to 0.15, P<0.000 1), overall diagnosis rate (RD=0.07, 95%CI 0.04 to 0.10, P<0.000 1) and the diagnosis rate of the malignant lesion (RD=0.06, 95%CI 0.02 to 0.09, P=0.004) of the ROSE combined with EBUS group were significantly higher than those of the EBUS group. Subgroup analysis showed that the diagnosis rates of pulmonary lesions (RD=0.12, 95%CI 0.08 to 0.17, P<0.000 01) and mediastinal lesions (RD=0.06, 95%CI 0.01 to 0.12, P=0.02) in the ROSE group was significantly higher than those in the EBUS group. The overall diagnosis rate and malignant diagnosis rate of ROSE combined with EBUS were 90% and 92%. The meta-analysis results of secondary outcomes showed that the number of lesions punctures (MD=–1.16, 95%CI –1.89 to –0.43, P=0.002) in the ROSE combined with EBUS group were significantly less than that in the EBUS group; there was no statistical difference in operation time (MD=0.09, 95%CI –5.22 to 5.39, P=0.97) or incidence of complications (RD=–0.06, 95%CI –0.13 to 0.01, P=0.1) between the two groups. Conclusion ROSE can improve the diagnostic efficiency of EBUS in pulmonary and mediastinal lesions, and has the value of the clinical application.

Objective To explore the impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. Methods The Medline, EMbase, CENTRAL, CNKI, Wanfang Data, VIP and China Biology Medicine from inception to May 2023 were searched by computer for studies about impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. The data were extracted from all the relevant literatures, and the quality of the data was assessed using the Newcastle-Ottawa Scale (NOS). All statistical analyses were conducted by the Stata 11.0 software. Results A total of 10 studies (NOS score ranging from 5 to 9 points) involving 643 patients were enrolled. The pooled results demonstrated that the pooled mortality of heart transplant recipients from SARS-CoV-2-positive donors was 4% (95%CI 2% to 5%). And the incidence of composite outcome, regarding graft failure, rejection and death as poor prognosis, was 7% (95%CI 5% to 9%). Besides, compared with recipients from SARS-CoV-2-negative donors, the pooled odds ratio (OR) value of death of SARS-CoV-2-positive donors was 0.68 (95%CI 0.38 to 1.22, Z=1.28, P=0.200). The pooled OR value of rejection rate was 0.41 (95%CI 0.27 to 0.64, Z=3.97, P<0.005). For the composite outcome, the pooled OR value was 0.50 (95%CI 0.37 to 0.69, Z=4.30, P<0.005). In addition, there was no statistical difference in the length of hospital stay between heart transplant recipients from SARS-CoV-2-positive donors and negative donors (SMD=–0.03, 95%CI –0.22 to 0.15, Z=0.36, P=0.720). Conclusion The application of heart from SARS-CoV-2-positive donor for transplantation is safe and feasible. However, further prospective studies with longer follow-up are still needed to verify its impact on long-term outcomes.

Objective To investigate the ultrasonographic characteristics of acute Stanford type A aortic dissection (ATAAD) involving the renal arteries and their relationship with renal function. Methods Patients with ATAAD admitted to Deyang People's Hospital from February 2013 to May 2023 were selected for the study. Based on whether the renal arteries were involved in the dissection, the patients were divided into two groups: a renal artery involvement group and a renal artery non-involvement group. General data and ultrasound characteristics of the two groups were compared. Logistic regression analysis and model correction were performed to analyze the relationship between ultrasound characteristics and renal function involvement in ATAAD patients. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of ultrasound characteristics for renal artery involvement in ATAAD patients. Additionally, patients in the renal artery involvement group were divided into normal renal function and abnormal renal function subgroups based on serum blood urea nitrogen (BUN) and serum creatinine (Scr) levels. Clinical data of the two subgroups were compared, and a log-binomial model was used to analyze the risk effects of ultrasound characteristics for abnormal renal function. Pearson correlation analysis was performed to assess the correlation between ultrasound characteristics of renal artery involvement and renal function indicators. Results A total of 163 patients were included, consisting of 106 males and 57 females, with a mean age of (50.06±10.46) years (ranging from 20 to 85 years). Significant differences in gender, Scr, and BUN were observed between the renal artery involvement group and the renal artery non-involvement group (P<0.001). Compared to the renal artery non-involvement group, the renal artery involvement group had an increased ascending aorta diameter, a greater proportion of ascending aortic dilation and poor renal perfusion (P<0.05). Logistic regression analysis indicated that ascending aorta diameter, ascending aortic dilation, and poor renal perfusion were independent factors for renal artery involvement (P<0.05). Ultrasonographic characteristics showed good predictive ability for renal artery involvement in ATAAD patients. Furthermore, the combination of the three characteristics yielded a higher predictive value for renal artery involvement. Compared to the normal renal function group, the abnormal renal function group had higher BUN and Scr levels, increased ascending aortic diameter, a greater proportion of ascending aortic dilation and poor renal perfusion (P<0.05). The log-binomial model analysis revealed that the risk ratios for ascending aortic diameter, ascending aortic dilation, and poor renal perfusion were statistically significant both before and after adjustment (P<0.05). Pearson correlation analysis revealed that ascending aortic diameter, ascending aortic dilation, and poor renal perfusion were strongly correlated with renal function parameters (P<0.05). Conclusion Ultrasound characteristics of ATAAD involving the renal arteries are associated with renal function. Ascending aorta diameter, ascending aortic dilation, and poor renal perfusion are independent risk factors for abnormal renal function.

Objective To examine the safety, efficacy and durability of totally endoscopic minimally invasive (TEMI) mitral valve repair in Barlow’s disease (BD). Methods A retrospective study was performed on patients who underwent mitral valve repair for BD from January 2010 to June 2021 in the Guangdong Provincial People’s Hospital. The patients were divided into a MS group and a TEMI group according to the surgery approaches. A comparison of the clinical data between the two groups was conducted. Results A total of 196 patients were enrolled, including 133 males and 63 females aged (43.8±14.9) years. There were 103 patients in the MS group and 93 patients in the TEMI group. No hospital death was observed. There was a higher percentage of artificial chordae implantation in the TEMI group compared to the MS group (P=0.020), but there was no statistical difference between the two groups in the other repair techniques (P>0.05). Although the total operation time between the two groups was not statistically different (P=0.265), the TEMI group had longer cardiopulmonary bypass time (P<0.001) and aortic clamp time (P<0.001), and shorter mechanical ventilation time (P<0.001) and postoperative hospitalization time (P<0.001). No statistical difference between the two groups in the adverse perioperative complications (P>0.05). The follow-up rate was 94.2% (180/191) with a mean time of 0.2-12.4 (4.0±2.4) years. Two patients in the MS group died with non-cardiac reasons during the follow-up period. The 3-year, 5-year and 10-year overall survival rates of all patients were 100.0%, 99.2%, 99.2%, respectively. Compared with the MS group, there was no statistical difference in the survival rate, recurrence rate of mitral regurgitation, reoperation rate of mitral valve or adverse cardiovascular and cerebrovascular events in the TEMI group (P＞0.05). Conclusion TEMI approach is a safe, feasible and effective approach for BD with a satisfying long-term efficacy.

The human gut microbiota regulates many host pathophysiological processes including metabolic, inflammatory, immune and cellular responses. In recent years, the incidence and mortality of lung cancer have increased rapidly, which is one of the biggest challenges in the field of cancer treatment today, especially in non-small cell lung cancer. Animal models and clinical studies have found that the gut microbiota of non-small cell lung cancer patients is significantly changed compared with the healthy people. The gut microbiota and metabolites can not only play a pro-cancer or tumor suppressor role by regulating immune, inflammatory responses and so on, but also be related with radiotherapy and chemotherapy of non-small cell lung cancer and the resistance of immunotherapy. Therefore, gut microbiota and related metabolites can be both potential markers for early diagnosis and prognosis in patients with non-small cell lung cancer and novel therapeutic targets for targeted drugs. This study will review the latest research progress of effect of gut microbiota on non-small cell lung cancer, and provide a new diagnosis and treatment ideas for non-small cell lung cancer.

Objective     To investigate the accuracy of 18F-FDG positron emission tomography/computed tomography (PET/CT) combined with CT three-dimensional reconstruction (CT-3D) in the differential diagnosis of benign and malignant pulmonary nodules. Methods     The clinical data of patients who underwent pulmonary nodule surgery in the Department of Thoracic Surgery, Northern Jiangsu People's Hospital from July 2020 to August 2021 were retrospectively analyzed. The preoperative 18F-FDG PET/CT and chest enhanced CT-3D and other imaging data were extracted. The parameters with diagnostic significance were screened by the area under the receiver operating characteristic (ROC) curve (AUC). Three prediction models, including PET/CT prediction model (MOD PET), CT-3D prediction model (MOD CT-3D), and PET/CT combined CT-3D prediction model (MOD combination), were established through binary logistic regression, and the diagnostic performance of the models were validated by ROC curve. Results     A total of 125 patients were enrolled, including 57 males and 68 females, with an average age of 61.16±8.57 years. There were 46 patients with benign nodules, and 79 patients with malignant nodules. A total of 2 PET/CT parameters and 5 CT-3D parameters were extracted. Two PET/CT parameters, SUVmax≥1.5 (AUC=0.688) and abnormal uptake of hilar/mediastinal lymph node metabolism (AUC=0.671), were included in the regression model. Among the CT-3D parameters, CT value histogram peaks (AUC=0.694) and CT-3D morphology (AUC=0.652) were included in the regression model. Finally, the AUC of the MOD PET was verified to be 0.738 [95%CI (0.651, 0.824)], the sensitivity was 74.7%, and the specificity was 60.9%; the AUC of the MOD CT-3D was 0.762 [95%CI (0.677, 0.848)], the sensitivity was 51.9%, and the specificity was 87.0%; the AUC of the MOD combination was 0.857 [95%CI (0.789, 0.925)], the sensitivity was 77.2%, the specificity was 82.6%, and the differences were statistically significant (P<0.001). Conclusion     18F-FDG PET/CT combined with CT-3D can improve the diagnostic performance of pulmonary nodules, and its specificity and sensitivity are better than those of single imaging diagnosis method. The combined prediction model is of great significance for the selection of surgical timing and surgical methods for pulmonary nodules, and provides a theoretical basis for the application of artificial intelligence in the pulmonary nodule diagnosis.

Objective     To compare the early and mid-term results between Fontan operation and anatomic correction for congenitally corrected transposition of the great arteries (ccTGA). Methods     The clinical data of 53 patients with ccTGA who underwent anatomic correction and Fontan operation from January 2009 to September 2021 in our hospital were reviewed, including 41 males and 12 females with a mean age of 55.02 (3-168) months. They were divided into an anatomic correction group (16 patients) and a Fontan operation group (37 patients) according to the operation. The hospitalization mortality, survival rate, postoperative complications, and free rate from re-intervention between the two groups were compared. Another 180 healthy children were recruited as a control group, and 14 children were matched with the propensity score matching method as a Fontan control group. The results of cardiopulmonary exercise testing (CPET) between the Fontan operation group and the Fontan control group were compared. Results     There were 2 (12.5%) early deaths and 3 (18.8%) early re-intervention in the anatomic correction group, while 1 death and 2 re-intervention in the Fontan operation group. In addition, there were 9 patients (56.3%) in the anatomic correction group and 6 (16.2%) patients in the Fontan operation group suffering from arrhythmia after operation, respectively. Compared with the anatomic correction group, cardiopulmonary bypass time, aortic cross-clamping time, intubation time and ICU stay were significantly shortened in the Fontan operation group (P<0.05). CPET results showed that, percent predicted max VO2 in the Fontan operation group was lower than that in the Fontan control group (0.84±0.11 vs. 0.99±0.12, P<0.05). The patients were followed up for 0.5-126.0 months. Two patients were lost in the Fontan operation group. There was no death and 1 re-intervention in the anatomic correction group, while no death or re-intervention in the Fontan operation group. The 1-year, 5-year and 10-year transplant-free survival rate of the anatomic correction group and the Fontan operation group was 87.5%, 87.5%, 87.5% and 97.3%, 97.3%, 97.3%, respectively (P>0.05). The 48 patients were classified as grade Ⅰ-Ⅱ in cardiac function in the last follow-up. Conclusion     There is no statistical difference in the transplant-free survival rate between the anatomic correction and the Fontan operation group. The postoperative complications in the Fontan operation group are decreased than those in the anatomic correction group. The Fontan operation is also a good choice, even though the patients with ccTGA meet the condition of the procedure of anatomic correction.
