Objective To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. Methods The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. ResultsAfter the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation (P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. ConclusionUlnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.
ObjectiveTo explore the adjuvant treatment options for elderly patients or those with low cardiopulmonary function who cannot tolerate lobectomy for peripheral solid pathological stage ⅠA (pⅠA) non-small cell lung cancer (NSCLC). MethodsA retrospective analysis was conducted on the clinical data of patients with peripheral solid pⅠA stage NSCLC treated with lobectomy and compromised sublobar resection (CSR) in our center from 2018 to 2019. The incidence of postoperative complications and independent predictors of postoperative recurrence were analyzed. Patients in the CSR group were divided into a targeted therapy group, a chemotherapy group, and an observation group based on postoperative treatment measures. The 3-year recurrence-free survival (RFS) rate and 5-year overall survival (OS) rate of the three subgroups before and after propensity score matching (PSM) were compared. ResultsA total of 586 patients were included, including 288 males (49.15%) and 298 females (50.85%), with a median age of 64.00 years. There were 335 patients of lobectomy and 251 patients of compromised sublobar resection. There was no statistically significant difference in the incidence of postoperative complications between the lobectomy group and CSR group [RR=0.987, 95%CI (0.898, 1.085), P=0.789). Multivariate analysis showed that gender, tumor location, and size were independent risk factors for recurrence after CSR. After PSM, 17 patients were enrolled in each of the three subgroups of CSR. Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the 3-year RFS rate (P=0.115) and 5-year OS rate (P=0.101) between the targeted therapy group and the chemotherapy group after PSM, but both were significantly better than those in the observation group (P=0.041, P=0.009). Compared with lobectomy, there was no statistically significant difference in the 3-year RFS rate (P=0.069) and 5-year OS rate (P=0.540) in the targeted therapy group, while the chemotherapy group and observation group were significantly inferior to the lobectomy group (P<0.05). ConclusionCSR for treating elderly patients or those with low cardiopulmonary function with peripheral solid pⅠA stage NSCLC does not increase the incidence of postoperative complications. Gender, tumor location, and size are independent risk factors for postoperative recurrence. In terms of 3-year RFS rate and 5-year OS rate, adjuvant targeted therapy after CSR is not only superior to chemotherapy or observation but is also not inferior to lobectomy.

This paper reviews the research progress of the application of artificial intelligence combined with omics data analysis in the diagnosis and treatment of non-small cell lung cancer (NSCLC), aiming to provide ideas for the development of a more effective artificial intelligence algorithm, and improve the diagnosis rate and prognosis of patients with early NSCLC through a non-invasive way.
ObjectiveTo explore the risk factors for lymph node metastasis in patients with T2 stage non-small cell lung cancer.MethodsThe clinical data of 271 patients with non-small cell lung cancer who underwent surgical treatment in our hospital from 2014 to 2017 were collected, including 179 males and 92 females, with an average age of 62.73±0.58 years. The patients were divided into N0, N1, and N2 groups according to the lymph node metastasis status. The clinical data of the patients in different groups were compared.ResultsThe body mass index (BMI, P=0.043), preoperative lymph node enlargement (P<0.001), and tumor diameter (P<0.001) were significantly different among groups. The BMI (OR=1.131, 95%CI 1.001-1.277, P=0.048) and preoperative lymph node enlargement (OR=3.498, 95%CI 1.666-7.342, P=0.001) were independent risk factors for N2 lymph node metastasis, and tumor diameter was an independent risk factor for both N1 (OR=1.538, 95%CI 1.067-2.218, P=0.021) and N2 (OR=1.814, 95%CI 1.196-2.752, P=0.005) lymph node metastasis.ConclusionPatients with high BMI or enlarged lymph nodes before surgery have a high risk for N2 lymph node metastasis, and those with large tumor diameter have a high risk for both N1 and N2 lymph node metastasis.
Objective To explore the association between the preoperative systemic immune-inflammation index (SII) and prognosis in non-small cell lung cancer (NSCLC) patients. Methods A comprehensive literature survey was performed on PubMed, Web of Science, EMbase, The Cochrane Library, Wanfang, and CNKI databases to search the related studies from inception to December 2021. The hazard ratio (HR) and 95% confidence interval (CI) were combined to evaluate the correlation of the preoperative SII with overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) in NSCLC patients. Results A total of 11 studies involving 9 180 patients were eventually included. The combined analysis showed that high SII levels were significantly associated with worse OS (HR=1.61, 95%CI 1.36-1.90, P<0.001), DFS (HR=1.50, 95%CI 1.34-1.68, P<0.001), and RFS (HR=1.17, 95%CI 1.04-1.33, P<0.001). Subgroup analyses also further verified the above results. Conclusion Preoperative SII is a powerful prognostic biomarker for predicting outcome in patients with operable NSCLC and contribute to prognosis evaluation and treatment strategy formulation. However, more well-designed and prospective studies are warranted to verify our findings.
ObjectiveTo explore the clinical value of three early predictive scale of lung injury (ALI) in patients with high risk of acute lung injury (ALI) after lung cancer surgery.MethodsA convenient sampling method was used in this study. A retrospective analysis was performed on patients with lung cancer underwent lung surgery. The patients were divided into an ALI group and a non-ALI group according to ALI diagnostic criteria. Three kinds of lung injury predictive scoring methods were used, including lung injury prediction score (LIPS), surgical lung injury prediction (SLIP) and SLIP-2. The differences in the scores of the two groups were compared. The correlation between the three scoring methods was also analyzed. The diagnostic value was analyzed by drawing receiver operating characteristic (ROC) curves.ResultsA total of 400 patients underwent lung cancer surgery, and 38 patients (9.5%) developed ALI after operation. Among them, 2 cases progressed to acute respiratory distress syndrome and were treated in intensive care unit. There were no deaths. The predictive scores of the patients in the ALI group were higher than those in the non-ALI group, and the difference was statistically significant (all P<0.001). There was a good correlation between the three scoring methods (allP<0.001). The three scoring methods had better diagnostic value for early prediction of high risk ALI patients after lung cancer surgery and their area under ROC curve (AUC) were larger than 0.8. LIPS score performed better than others, with an AUC of 0.833, 95%CI (0.79, 0.87).ConclusionThree predictive scoring methods may be applied to early prediction of high risk ALI patients after lung cancer surgery, in which LIPS performs better than others.
Objective To evaluate the efficacy and safety of whole lung lavage in the treatment of pulmonary alveolar proteinosis ( PAP) .Methods Twelve patients who were diagnosed as PAP from September 2008 to October 2011 in Hunan Occupational Disease Hospital were recruited in the study. The changes of dyspnea symptom, lung-function, arterial blood gas, and chest image were compared before and after whole lung lavage treatment. Meanwhile, the safety of lung lavage was evaluated. Results All patients were relieved from dyspnea. The lung function, hypoxia, hyperventilation, and chest image were all obviously improved. The vital signs in the process of lung lavage were stable without serious complications. Conclusion Whole lung lavage is an effective and safe treatment for PAP.
Objective To compare outcomes after single versus bilateral lung transplantation in patients with end-stage chronic obstructive pulmonary disease (COPD) with retrospective cohort study, and to provide a reference for surgical selection. Methods One hundred and two patients with end-stage COPD who received lung transplantation in Wuxi People's Hospital affiliated to Nanjing Medical University from January 2010 to May 2019 were evaluated, including 97 males and 5 females, aged from 42 to 82 years, with an average age of (59.8±8.0) years. Recipients were divided into single lung transplantation (SLT) group (31 cases) and bilateral lung transplantation (BLT) group (71 cases). Preoperative characteristics, postoperative outcomes, postoperative complications, functional improvement and survival between the two groups were analyzed retrospectively. Results The SLT group were significantly older than the BLT group [(62.6±8.8) years vs. (58.6±7.4) years, P<0.05], which was consistent with the practice mode of single lung transplantation in the elderly patients in this center. The FEV1% predicted and the six‐minute walk distance (6-MWD) in the BLT group were better than those in the SLT group (P<0.05). The cumulative survival rate in 1, 3 and 5 years after operation in the BLT group was higher than that in the SLT group (70.4%, 63.2%, 61.5%, respectively vs. 67.7%, 58.1%, 54.6%, respectively), but there was no statistical difference (P=0.388). The two groups were comparable in other preoperative clinical data (P>0.05). The cold ischemia time and total operation time were shorter in the SLT group than in the BLT group, and the intraoperative blood loss was less than that in the BLT group, but more patients required intraoperative extracorporeal membrane oxygenation support than the BLT group (P<0.05). There were no significant differences in postoperative ventilator support, reoperation, length of intensive care unit stay, postoperative hospital stay, and perioperative mortality (P>0.05). In terms of postoperative complications, the incidence of primary graft dysfunction grades 3 was higher in the SLT group than in the BLT group (35% vs. 8%, P=0.001). There were no significant differences between the two groups in chest complications, airway complications, acute rejection, infection, and bronchial occlusion syndrome (P>0.05). Nine patients (29%) developed acute native lung hyperinflation in the SLT group. ConclusionsBilateral lung transplantation is superior to single lung transplantation in the treatment of end-stage COPD. The advantage is mainly reflected in the simple perioperative management, better functional improvement after operation. Single lung transplantation as a beneficial supplement to double lung transplantation should still be considered in selected patients.
