Association between hip fracture fixation methods and bone mineral density T-value in middle-aged and elderly patients with hip fractures.

Objective: To examine the association of proximal femoral nail anti-rotation (PFNA) and dynamic hip screw (DHS) with bone mineral density T-value (BMDT) in middle-aged and elderly patients suffering from hip fractures.

Methods: Clinical data were collected from 110 patients with hip fractures who underwent internal fixation surgery between October 2020 and June 2021. Patients treated with DHS were included in the control group, and those treated with PFNA were classified into the observation group.

[Effect of spironolactone on left ventricular remodeling in patients with acute myocardial infarction].

Objective: To investigate the effect of spironolactone on left ventricular remodeling (LVRM) in patients with acute myocardial infarction.

Methods: In this multicentric, randomized, controlled study, spironolactone 40 mg/d was randomly administered in addition to the routine treatment for patients with AMI. During the 6 months the serum PIIINP, BNP and echocardiography were examined in all patients to assess myocardial fibrosis, LV function and volume.
