Objective:Concentrated growth factors (CGF),a new generation of platelet concentrate products,appears to have more abundant growth factors because of its special centrifugation process.However,there are few studies supporting this.This study was designed to evaluate the effect of CGFs in the treatment of Ⅱ ° furcations of mandibular molars.Methods:In the present study,thirty-one Ⅱ ° furcation involvements in twenty mandiblular molars were included and randomly divided into two groups.The furcation involvements in the experimental group were treated with bone graft therapy combined with CGFs,and the furcation involvements in the control group were treated with bone graft therapy alone.The clinical examination and cone beam computed tomography (CBCT) were performed at baseline and 1 year post-surgery for the two groups.The changes of clinical and CBCT data at baseline and 1 year postsurgery were compared between the experimental group and the control group.Results:At baseline,there were no significant differences between the two groups in the probing depth (PD),vertical clinical attachment loss (CAL-V) and horizontal clinical attachment loss (CAL-H):PD (7.36 ± 2.32) mm (the experimental group) vs.(7.53 ±2.06) mm (the control group);CAL-V (8.69 ± 1.65) mm (the experimental group) vs.(8.81 ±1.53) mm (the control group);CAL-H (5.24 ±2.01) mm (the experimental group) vs.(5.35 ±2.14) mm (the control group).At the end of 1 year post-surgery,the clinical parameters of both groups were significantly improved (P ＜ 0.001).For the experimental group,the average vertical attachment gain was (2.78 ± 1.66) mm,and the vertical attachment loss was improved significantly compared with the baseline (P ＜ 0.001);the average horizontal attachment gain was (2.10 ± 1.89) mm,and the horizontal attachment loss were improved significantly compared with the baseline (P ＜ 0.001).Furthermore,the improvement degree of the experimental group was significantly higher than that of the control group (P ＜ 0.001).At baseline,there were no statistical differences in the vertical bone loss (BL-V) or horizontal bone loss (BL-H) between the two groups (P ＞ 0.05):BL-V (5.08 ± 2.17) mm (the experimental group) vs.(5.84 ± 2.65) mm (the control group);BL-H (5.85 ±2.13) mm (the experimental group) vs.(6.01 ±2.27) mm (the control group).At 1 year post-surgery,both groups showed significant radiographic bone gain at vertical and horizontal directions compared with baseline (P ＜ 0.001).For the experimental group,the average vertical radiographic bone gain was (2.20 ± 1.98) mm,the horizontal radiographic bone gain was (2.51 ±2.18) mm,the vertical and horizontal radiographic bone loss were both significantly reduced compared with the baseline (P ＜ 0.001).For the control group,the average vertical radiographic bone gain was (1.89 ± 2.15) mm,the horizontal radiographic bone gain was (1.30 ± 2.47) mm,the vertical and horizontal radiographic bone losses were both significantly reduced compared with the baseline (P ＜ 0.001).And the experimental group showed significantly higher bone gain at vertical and horizontal directions compared with the control group (P ＜ 0.001).Conclusion:Within the limitation of the present study,CGFs showed positive role in the treatment of Ⅱ° furcation involvements of mandibular molars.

Aquaporin4(AQP4),a member of the aquaporin family,is mainly expressed inastrocytes end-feet in the central nervous system. A large number of experimental studies have show n that AQP4 expression plays an important role in the occurrence, development, and regression of brain edema after different types of stroke. In addition, the AQP4 expression can affect the development process of cerebrovascular disease through the mechanisms such as affecting the integrity of the blood-brain barrier and promoting astrocyte migration, nerve regeneration, and neuroinflammatory response. Investigation of regulation mechanisms of AQP4 in transmembrane transport of substance in brain and intracel ular and extracel ular environmental balance and its expression in model of cerebrovascular disease have an important significance for understanding the occurrence, development, protection, and treatment of clinical cerebrovascular disease.
