Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

Objective:To investigate the correlation between the levels of CC chemokine ligand 2 (CCL2) and periostin (POSTN) in serum and alveolar lavage fluid of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) complicated with respiratory virus infection and lung function.Methods:From March 2020 to March 2023, 96 patients with acute exacerbation of COPD admitted to our hospital were collected. Among them, 34 patients with concurrent respiratory virus infection were included in the infected group, and 62 patients without respiratory virus infection were included in the uninfected group. Enzyme linked immunosorbent assay (ELISA) was applied to detect the expression levels of CCL2 and POSTN in serum and alveolar lavage fluid. Pearson method was applied to analyze the correlation between CCL2 and POSTN levels in serum and alveolar lavage fluid of infected patients and lung function indicators.Results:The levels of CCL 2 ( t=12.633, 9.253 2, 2) and POSTN ( t=12.370, 7.383) were significantly increased in the infected group compared with the uninfected group ( P<0.05). Compared with the uninfected group, the 6-minute walking test (6 MWT), peak expiratory flow rate (peak expiratory flow, PEF), forced expiratory volume at the first second (forced expiratory volume in one second, FEV 1), and the forced lung capacity (forced vital capacity, FVC), FEV 1/FVC, and maximum middle breath mean flow rate (maximal mid-expiratory flow curve, MMEF) were significantly lower ( t=14.141, 24.165, 22.421, 21.223, 5.278, 29.456, P<0.05). Correlation analysis showed that the levels of CCL2 and POSTN in the serum and alveolar lavage fluid of the infected group were negatively correlated with the levels of 6MWT, PEF, FEV1, FVC, FEV1/FVC, and MMEF ( P<0.05). Conclusions:CCL2 and POSTN levels were highly expressed in serum and alveolar lavage fluid of patients with respiratory virus infection during acute exacerbation of COPD, which were closely related to lung function.

Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.
