Objective To investigate the relationship between gene polymorphism of interleukin (IL) -1 and peri-implantitis. Methods A case-control experimental design was used in this study. Moreover, using a bioinformatics analysis, we selected three tagged single nucleotide polymorphisms (SNP) suitable for the Chinese population. Patients with peri-implantitis (n = 116) and 87 patients without peri-implantitis were included. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to tag SNP of IL-1α, IL-1β, and IL-1γn. Results The rs2856838 locus of the AA genotype of IL-1α was associated with a higher risk of implant periodontitis than the GG genotype. There was no statistical difference between the two groups with regard to the other SNP. Conclusion The AA genotype of rs2856838 is associated with periprosthetic inflammation.

Objective    To compare the in-hospital and midterm outcomes after simultaneous hybrid coronary revascularization (HCR) with off-pump coronary artery bypass grafting (OPCAB) in diabetic patients with multivessel coronary artery disease. Methods    One hundred thirty-two diabetic patients with multivessel coronary artery disease underwent one-stop HCR at Fuwai Hospital from January 2010 to January 2015. These patients were 1∶2 matched with those who underwent OPCAB using propensity score matching. Results    Simultaneous HCR had less chest tube drainage (618 (420, 811) ml vs. 969 (711, 1 213)ml, P<0.001), lower transfusion rate (19.7% vs. 34.1%, P=0.026), shorter mechanical ventilation time (11.6 (8.2, 14.8) h vs. 16.0 (12.1, 18.7) h, P<0.001), and shorter stay in intensive care unit (21.5 (18.8, 42.0)   h vs. 44.6 (23.7, 70.1) h, P<0.001) than OPCAB. During over median 40 months follow-up, simultaneous HCR offered similar major adverse cardiac or cerebrovascular events (MACCE) rate (6.8% vs 9.0%, P=0.826), but lower stroke rate (0%vs 3.0%, P=0.029), compared with OPCAB. Conclusion    For selected patients with diabetes, simultaneous HCR provides a safe and effective revascularization alternative. It decreases perioperative invasiveness and incurred similar and favorable midterm outcomes with OPCAB.
