37 cases of skin pruritus were treated by acupuncture and cupping method. After two courses of the treatments, the total effective rate was 94.6%.

Objective To study the effect of paeonol (PAE) and PNS on the expression of transforming growth factor (TGF)- beta 1/ Smad2/3 pathway in rats with acute myocardial infarction (AMI), and the possible molecular mechanism thereof. Methods Model of AMI was made using left anterior descending coronary branch ligation. According to the inter?vention methods rats were divided into model group, PAE group (8 mg·kg-1), PNS group (40 mg·kg-1), PAE (4 mg·kg-1)+PNS (20 mg·kg-1) low dose group, PAE (8 mg·kg-1)+PNS (40 mg·kg-1) high dose group and captopril positive control group (10 mg · kg-1). Rats without ligation were used as Sham operation group. Left ventricular systolic blood pressure (LVSP), left ventricular diastolic pressure (LVEDP) and the maximum rise and fall rate (/dtmax DP) were detected after 28-day treat?ment. HE staining was used to observe changes of myocardial tissue. The protein expression levels of TGF-β1 and Smad2/3 were detected by Western blot assay. Results There were significant differences in parameters used for detecting treatment group and model group, formula group and single drug group, formula high dose group and formula low dose group (P <0.01). The model group showed pathological changes. All treatment groups showed different degrees of pathological improve?ment. There was the most significant improvement in formulae group and captopril group. Compared with the model group, TGF-β1 and Smad2/3 protein expressions were decreased in treatment group. The expression levels of TGF-β1 and Smad2/3 were significantly decreased in formula group than those of PAE group and PNS group, and lower levels in formula high dose group than those of formula low dose group (P<0.05). Conclusion Paeonol and PNS can inhibit the expressions of TGF-β/Smad 2/3 protein in rats with AMI, by blocking TGF-β/Smad pathway.

Objective To study the effect of paeonol (PAE) and panax notoginseny saponins (PNS) on the expressions of collagenⅠandⅢprotein and mRNA in rats with acute myocardial infarction (AMI), and to explore the molecular mecha?nism of improving myocardial fibrosis. Methods The rat model of AMI was made using the left anterior descending coro?nary branch ligation.According to the intervention rats were divided into model group, PAE (8 mg/kg) group, PNS (40 mg/kg) group, PAE (4 mg/kg)+PNS (20 mg/kg) group, PAE (8 mg/kg)+PNS (40 mg/kg) group and captopril positive control group (10 mg/kg). Sham operation group, only wear line without ligation. The left ventricular mass index (LVMI) was detected after treatment for 28 d. Masson staining was used to observe changes of myocardial fibrosis. Western blot assay and RT-PCR technique were used to detect protein and mRNA expression levels of collagenⅠandⅢ. Results The values of LVMI were increased in model group compared with those of sham operation group and treatment groups. Compared with PAE group and PNS group, values of LVMI were significantly decreased in PAE (4 mg/kg)+PNS (20 mg/kg) group and PAE (8 mg/kg)+PNS (40 mg/kg) group. There was a more significant decrease in formula high dose group (P < 0.01). The model group showed pathological change. There were different degrees of improvement in pathological structure in all treatment groups, more sig?nificant improvement was found in formula low dose group, formula high dose group and captopril positive control group. There were different degrees of increase in expressions of collagenⅠandⅢprotein and mRNA in model group compared with those of sham operation group and treatment groups. Compared with PAE group and PNS group, the protein and mRNA expression levels of collagenⅠandⅢwere significantly decreased in formula low dose group and formula high dose group,more significant decreased was found in formula high dose group (P<0.05). Conclusion Compound of paeonol and PNS can improve myocardial fibrosis in myocardial infarction rats, which may be related with reduced expressions of collagenⅠandⅢprotein and mRNA.

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.
