Article Synopsis
- The study investigated how macrophages and PD-1 expression influence tumor-infiltrating lymphocytes (TILs) and treatment outcomes in advanced cholangiocarcinoma (CCA) patients, exploring their relationship with clinical features.
- Twenty-five metastatic CCA patients and 19 healthy controls were analyzed for immune cell levels using flow cytometry, revealing significant differences in CD4, CD8, and macrophage levels between groups.
- Findings indicated that higher CD4 levels correlate with better progression-free survival (PFS), while increased PD-1 expression and certain macrophage profiles are linked to poorer outcomes, suggesting that immune factors could help predict treatment responses in CCA.
No correlation exists between coracoid tunnel widening and loss of reduction after arthroscopic acromioclavicular fixation using tightrope system.

Purpose: To detect the widening of the tunnel of the coracoid process after arthroscopic fixation of acute acromioclavicular joint (ACJ) dislocation using the TightRope system and its correlation with loss of reduction and functional scores.
Methods: From 2016 to 2018, a prospective study was performed on twenty-three patients with acute grade III-V ACJ dislocation. Arthroscopic TightRope repair of the ACJ was performed.
