OBJECTIVE: Therapeutic angiogenesis has become a promising approach for treating ischemic heart disease (IHD). The present study aims to investigate the effects of Qishen Granule (QSG) on angiogenesis in myocardial ischemia (MI) and the potential mechanism. METHODS: In vivo study was conducted on rat model of myocardial infarction. QSG was performed daily at a dose of 2.352 g/kg for four weeks. Cardiac function was assessed by echocardiogram and pro-angiogenic effects were evaluated by Laser Doppler and CD31 expression. Oxygen-glucose deprivation (OGD) was applied in cultured human umbilical vein endothelial cells (HUVECs). Cell viability, wound healing and tube formation assay were used to test functions of HUVECs. ELISA and Western blots were used to assess protein expressions of bone morphogenetic protein 2-delta-like 4-notch homolog 1 (BMP2-Dll4-Notch1) signaling pathway. RESULTS: The results showed that QSG improved heart function, cardiac blood flow and microvessel density in myocardial ischemic rats. In vitro, QSG protected HUVECs by promoting the cell viability and tube formation. QSG upregulated bone morphogenetic protein-2 (BMP2) and downregulated delta-like 4 (Dll4) and notch homolog 1 (Notch1) expressions both in rats and HUVECs. CONCLUSION QSG protected against MI by promoting angiogenesis through BMP2-Dll4-Notch1 pathway. BMP2 might be a promising therapeutic target for IHD.

Risk assessment models for periodontal disease provide dentists with a precise and consolidated evalua-tion of the prognosis of periodontitis,enabling the formulation of personalized treatment plans.Periodontal risk assess-ment systems have been widely applied in clinical practice and research.The application fields of periodontal risk assessment systems vary based on the distinctions between clinical periodontal parameters and risk factors.The assess-ment models listed below are commonly used in clinical practice,including the periodontal risk calculator(PRC),which is an individual-based periodontal risk assessment tool that collects both periodontal and systemic information for pre-diction;the periodontal assessment tool(PAT),which allows for quantitative differentiation of stages of periodontal dis-ease;the periodontal risk assessment(PRA)and modified periodontal risk assessment(mPRA),which are easy to use;and the classification and regression trees(CART),which assess the periodontal prognosis based on a single affected tooth.Additionally,there are orthodontic-periodontal combined risk assessment systems and implant periapical risk as-sessment systems tailored for patients needing multidisciplinary treatment.This review focuses on the current applica-tion status of periodontal risk assessment systems.

Periodontal risk assessment systems have been widely applied in clinical practice and research. The application fields of periodontal risk assessment systems vary based on the distinctions between clinical periodontal parameters and risk factors. The assessment models listed below are commonly used in clinical practice, including the periodontal risk calculator (PRC), which is an individual-based periodontal risk assessment tool that collects both periodontal and systemic information for prediction; the periodontal assessment tool (PAT), which allows for quantitative differentiation of stages of periodontal disease; the periodontal risk assessment (PRA) and modified periodontal risk assessment (mPRA), which are easy to use; and the classification and regression trees (CART), which assess the periodontal prognosis based on a single affected tooth.
