OBJECTIVE

To analyze the effects of sodium hyaluronate administration on the serum levels of antioxidase, substance P (SP), and neuropeptide Y (NPY) in patients undergoing locking plate fixation (LPF) for tibial plateau fractures (TPF).

METHODS

We retrospectively analyzed the records of 66 patients with TPF who received treatment in the Beijing Chao-yang Hospital[PJMS1][2] from February 2017 to August 2020. According to the treatment records, 33 patients underwent LPF surgery (control-group), and 33 patients underwent LPF plus sodium hyaluronate treatment (observation-group). The levels of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT) and total antioxidant capacity (TAC)), SP and NPY.

RESULTS

Seven days after LPF operations, both groups showed lower levels of SOD, CAT, and TAC compared to pre-surgery levels, while levels of SP and NPY were higher. However, the observation group showed higher levels of SOD, CAT, and TAC compared to the control group, and lower levels of SP and NPY in the control group (<0.05).

CONCLUSION

The treatment of TPF with LPF plus sodium hyaluronate administration has been shown to effectively reduce oxidative stress reactions, improve SP and NPY levels.[PJMS3][4].
