Objective:To investigate the clinical efficacy of amoxicillin combined with metronidazole in the treatment of peri-implantitis and its effect on serum matrix metalloproteinase-8 (MMP-8), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) levels.Methods:Sixty-four patients with peri-implantitis who received treatment from January 2017 to December 2019 in Xiasha Hospital, SiR Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this study. They were randomly assigned to receive treatment with metronidazole (control group, n = 32) or amoxicillin combined with metronidazole (observation group, n = 32). Clinical efficacy, periodontal pocket depth (PD), clinical attachment level (CAL), sulcus bleeding index (SBI), plaque index (PLI), matrix metalloproteinase-8 (MMP-8), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) levels and the incidence of adverse reactions were compared between the control and observation groups. PD, CAL, SBI and PLI were correlated with MMP-8, TNF-α and IL-1β levels. Results:The clinical efficacy in the observation group was significantly higher than that in the control group [93.75% (30/32) vs. 75.00% (24/32), χ2 = 4.267, P < 0.05]. After treatment, PD [(3.02 ± 0.24) mm], CAL [(1.70 ± 0.14) mm], SBI [(11.54 ± 3.26)%], PLI (0.87 ± 0.11) in the observation group were significantly lower than those in the control group [(4.47 ± 1.37) mm, (3.77 ± 1.06) mm, (18.84 ± 5.11)%, (1.12 ± 0.15), t = 5.897, 10.952, 6.813, 7.603, all P < 0.01]. After treatment, serum MMP-8 [(0.78 ± 0.23) μg/L], TNF-α [(71.24 ± 10.33) μg/L], IL-1β [(1.20 ± 0.14) μg/L] levels in the observation group were significantly lower compared with the control group [(1.12 ± 0.35) μg/L, (113.28 ± 15.73) μg/L, (2.55 ± 1.02) μg/L, t = 4.592, 12.637, 7.417, all P < 0.01]. Spearman correlation coefficient analysis showed that PD, CAL, SBI and PLI were positively correlated with serum MMP-8, TNF-α and IL-1β levels (all P < 0.01). Conclusion:Amoxicillin combined with metronidazole is highly effective in the treatment of peri-implantitis because it can promote plaque regression, reduce inflammatory reaction, and has a certain clinical promotion value.

Objective To investigate the early nursing intervention on recovery of upper limb edema after radical mastectomy, and subjective comfort of patients and satisfaction degree with the service quality of nursing staff.
