[Abstract] Objective: To investigate the expression of galectin-3 in bladder cancer tissues and its correlation with clinicopathological characteristics of bladder cancer patients, as well as to explore its effect on the proliferation, invasion and apoptosis of bladder cancer T24 cells. Methods:Atotal of 104 cases of pathologically confirmed bladder cancer tissues and the corresponding adjacent tissues were collected from the patients treated at the Affiliated Hospital of North Sichuan Medical College from May 2014 to June 2016. Immunohistochemistry staining was used to determine the galectin-3 protein expression in both cancer and adjacent tissues, and the correlations between galectin-3 expression and clinical pathological features were analyzed. siRNA-Gal3 and siRNA-Control were transfected into T24 cell, respectively. The expression of galectin-3 protein was detected by Western blotting, the proliferation of cells was detected by MTT assay; the invasion of cells was detected by Transwell assay; and the cell apoptosis was determined by Flow cytometry. Results: The positive rate of galectin-3 in bladder cancer tissues was significantly higher than that in adjacent tissues (73.1% vs 9.6%, P<0.05). The expression of galectin-3 in bladder cancer was correlated with histological grade, depth of invasion, lymph node metastasis and TNM stage (all P <0.05), but not with sex and age (P>0.05). The expression of galectin-3 was down-regulated significantly by siRNAGal3 (P<0.05). After interference with galectin-3, the proliferation and invasion of T24 cells was significantly decreased (all P<0.05) but the apoptosis was significantly increased (P<0.05). Conclusion: Galectin-3 is over-expressed in bladder cancer and is closely related to the clinicopathological features of bladder cancer patients. Interference of galectin-3 protein expression can inhibit proliferation and invasion and promote cell apoptosis of bladder cancer T24 cells. ··

Objective    To investigate the short-term quality of life in patients after single-direction video-assisted thoracic surgery (VATS) for lung cancer, and explore the related influencing factors. Methods    Patients who underwent single-direction VATS for lung cancer in the Department of Thoracic Surgery, West China Hospital, Sichuan University from July 2020 to August 2021 were continuously selected. The QLQ-C30 and QLQ-LC13 were used to evaluate the quality of life of the patients after the surgery, and the influencing factors were analyzed. Results    A total of 193 patients were collected. There were 73 males aged 59.44±11.40 years, and 120 females aged 53.73±11.15 years. The QLQ-C30 score of the patients after single-direction VATS for lung cancer was 69.09±20.21 points. Univariate analysis and Pearson correlation analysis showed that age, occupation, anesthesia time, postoperative complications, postoperative antibiotic use time, postoperative hospital stay, insomnia, economic stress, hemoptysis, chest pain, dysphagia, arm or shoulder pain were associated with the quality of life (P≤0.05). The results of multiple regression analysis showed that anesthesia time, economic pressure, insomnia and chest pain had a significant impact on the overall quality of life 30 days after the surgery (P≤0.05). Conclusion    The anesthesia time, economic pressure, insomnia and chest pain are independent influencing factors for the quality of life after the VATS lung cancer surgery.
