OBJECTIVE To investigate the efficacy and safety of aerosol inhalation of polycolistin B in the treatment of severe pneumonia combined with mechanical ventilation， and to provide a reference of real-world data for clinical drug therapy. METHODS A retrospective cohort study was conducted to analyze the clinical data of 87 patients with severe pneumonia combined with mechanical ventilation at the First Affiliated Hospital of Shandong First Medical University from January 2021 to February 2023. According to route of administration， all patients were divided into combined group （24 cases， receiving aerosol YXH2021ZX013） inhibition of polycolistin B combined with intravenous dripping） and routine group （63 cases， intravenous dripping of polycolistin B alone）. The differences in efficacy （mortality，clinical response rate and bacterial clearance rate）and safety （elevated serum creatinine， bronchospasm and skin pigmentation） were compared between two groups； the influential factors of primary outcome index as mortality were analyzed through univariate analysis and multivariate Logistic regression analysis. RESULTS In terms of efficacy， there were no statistical differences in mortality（37.50% vs. 41.27%， P＝0.749）， clinical response rate （54.17% vs. 55.56%， P＝0.907） and bacterial clearance rate （45.83% vs. 44.44%， P＝0.907） between the two groups. In terms of safety， the incidence of bronchospasm in the combined group was significantly higher than that of the routine group （12.50% vs. 0， P＝0.028）， but the differences in incidence of elevated serum creatinine and skin pigmentation between two groups were not statistically significant （P＞0.05）. Univariate analysis showed that the moralities were higher in the case of infected with Acinetobacter baumannii， Klebsiella pneumoniae and combined use of quinolones （P＜0.05）； multivariate Logistic regression analysis showed that infection with A. baumannii （OR＝3.36， P＝0.014） and combined use of quinolones （OR＝3.54， P＝0.013） were independently associated with mortality （P＜0.05）. CONCLUSIONS For severe pneumonia patients with mechanical ventilation， intravenous dripping of polycolistin B combined with aerosol inhalation does not show superior efficacy compared with intravenous dipping of polycolistin B alone， but significantly increases the incidence of bronchospasm. Infection with A. baumannii and combined use of quinolones are independent risk factors for the increase of mortality.

Objective To analyze the dynamic changes and the influencing factors of T lymphocyte subsets in recipients with stable graft status within 1 year after lung transplantation. Methods Clinical data of 41 recipients with stable graft status after allogeneic lung transplantation were analyzed. The absolute value and ratio of T lymphocyte subsets in peripheral blood from recipients were measured by flow cytometry before operation, 2 weeks and each month (within 1 year) after operation, respectively. The effects of age, gender, body mass index (BMI), surgical method, incidence of primary graft dysfunction (PGD) after operation, and primary disease upon the absolute values of T lymphocytes were evaluated. Results Within 1 year after lung transplantation, the absolute values of CD3⁺, CD3⁺CD4⁺, CD3⁺CD8⁺T lymphocytes and CD4⁺/CD8⁺ ratio were changed over time (all P < 0.001). Compared with preoperative values, there was no statistical significance in the absolute values of CD3⁺ and CD3⁺CD4⁺T lymphocytes at 12 months after operation (P=0.659, 0.109), whereas the absolute value of CD3⁺CD8⁺T lymphocytes was increased (P=0.02) and the CD4⁺/CD8⁺ ratio was decreased (P < 0.001). Age, gender, BMI, surgical method and incidence of PGD after operation exerted no significant effect on the dynamic changes of absolute values of CD3⁺CD4⁺ and CD3⁺CD8⁺T lymphocytes (all P > 0.05). Primary disease before lung transplantation exerted no effect on the changes of CD3⁺CD4⁺T lymphocytes, whereas the postoperative absolute value of CD3⁺CD8⁺T lymphocytes was higher in recipients with infectious lung diseases (P < 0.05). Conclusions The absolute values of CD3⁺, CD3⁺CD4⁺, CD3⁺CD8⁺T lymphocytes in recipients with stable graft status after lung transplantation are relatively low in the early stage after lung transplantation, then gradually restore, and stabilize at 6 months after operation. Dynamic changes are not associated with age, gender, BMI, surgical method and incidence of PGD after operation of recipients.

Acute cellular rejection (ACR) is a common complication after lung transplantation, which is mainly caused by the immune response of T lymphocytes recognizing the major histocompatibility complex on the cellular surface of grafts. It is currently considered as the main pattern of acute rejection. ACR is not only a direct cause of death of recipients, but also a high-risk factor for chronic rejection after lung transplantation. Nevertheless, it is a challenging task to deliver the diagnosis and treatment of ACR following lung transplantation. In this article, new progresses on the risk factors, pathogenesis, diagnosis and treatment of ACR in lung transplant recipients were summarized, aiming to improve the diagnostic and treatment efficiency of ACR and prolong the survival of recipients.

Objective:To explore the clinical manifestations and imaging features of nocardia infection (NI) after lung transplantation and boost the diagnosis and treatment of NI.Methods:From January 2018 to December 2019, basic profiles, clinical manifestations, laboratory examinations, imaging features and treatment outcomes of 5 lung transplant recipients with a diagnosis of NF were retrospectively analyzed and summarized with the relevant literatures. There were 4 males and 1 female with a median age of 66(26-69) years. 3 patients were single-lung transplantation, 2 patients were bilateral-lung transplantation. The median time from an initial diagnosis of NI to lung transplant surgery was 6(5-19) months. Common symptoms included fever, cough with yellow phlegm and shortness of breath. Laboratory findings showed lymphopenia, significantly high C-reactive protein levels, a slight elevation of procalcitonin, hypoproteinemia and anemia. The major manifestations of high-resolution computed tomography (CT) included multiple nodules, consolidation, cavitation and pleural effusion.Results:Five strains of N. farcinica were identified from bloodstream infection ( n=2) and pulmonary infection ( n=3). After with a combined therapy of two sensitive agents, all patients improved and were discharged from hospital. During follow-ups, one patient died and the remainders were cured. Conclusions:Nocardia infection occurs in lung transplant recipients mostly within 1 year post-operation. There are non-specific symptoms and imaging features of multiple nodules and consolidation. Combination therapy of sensitive agents is indicated for lung transplant recipients with NI.
