[Comparison of the stability of dual INFIX and INFIX combined with sacroiliac screw fixation for C1 type pelvic fractures].

Objective: To evaluate the biomechanical stability of dual anterior subcutaneous internal fixation (INFIX) in pelvic C1 fractures by finite element analysis, and to compare it with INFIX combined with sacroiliac screws to determine whether it is sufficient to replace the combined fixation of anterior and posterior rings.

Methods: The pelvic CT data of a 43-year-old female volunteer were imported into the computer and the normal pelvic model and pelvic C1 fractures model were constructed using Mimics, Workbench and other software. The latter was fixed with dual INFIX and INFIX combined with sacroiliac screws, respectively.

[Clinical Features and Prognosis of Patients with Diffuse Large B-Cell Lymphoma of the Breast].

Objective: To explore the clinical characteristics and prognosis of patients with diffuse large B-cell lymphoma (DLBCL) of the breast.

Methods: The clinical data of 28 DLBCL patients admitted to Shanxi Provincial Cancer Hospital from January 2013 to January 2023 were retrospectively analysed, including 13 cases of primary breast DLBCL (PB-DLBCL) and 15 cases of secondary breast DLBCL (SB-DLBCL), and the data of their clinical manifestations, laboratory tests, pathological examinations, treatment protocols, and follow-up were statistically analyzed.

Results: There were significant differences in IPI score, LDH level and β- microglobulin between PB-DLBCL and SB-DLBCL patients ( < 0.
