Conventional treatments for dry eye disease, such as artificial tears and anti-inflammatory drugs, can only alleviate symptoms, and it is difficult to achieve etiological repair with these treatments. In recent years, stem cell and exosome-based therapies have emerged as promising research hotspots for dry eye disease treatment, owing to their immunomodulatory, tissue-regenerative, and anti-inflammatory properties. Multiple basic and clinical studies have preliminarily confirmed the therapeutic potential of stem cells and exosomes in treating dry eye disease. This review summarizes recent advances in stem cell and exosome-based treatments for dry eye disease and analyzes their current regulatory landscapes, intending to serve as a reference for investigators within the field.
Objective To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.
