RESUMO

<p><b>OBJECTIVE</b>This study aimed to establish a SD rat model of chronic periodontitis (CP) merged with hyperlipidemia (HL), perform periodontal treatment, detect the expression of partial C-reactive protein (CRP) and Porphyromonas gingivalis (P. gingivalis) in the rat carotid artery, and explore the relationship between periodontitis and atherosclerosis.</p><p><b>METHODS</b>SD rats were randomly divided into three groups: control group (A), HL group (B), and CP+HL group (C). Group C rats were divided into natural process group (C1), scaling and root planning group (C2), and tooth extraction group (C3). Group C2 rats were randomly divided into C2-1 (scaling and root planning group) and C2-2 (scaling and root planning+minocyline+systemic antibiotics group). Group C3 rats were randomly divided into C3-1 (tooth extraction group) and C3-2 (tooth extraction+systemic antibiotic group). One rat from group B was randomly selected and sacrificed after 15 weeks. Subsequently, the carotid vascular tissue was collected for oil red O staining. Modeling was successful when foam cell formation was observed. Periodontal treatments were conducted twice, and euthanasia was performed after the experiment. Moreover, double-carotid artery bifurcation was carried out to detect the expression of CRP and P. gingivalis. Immunohistochemical and 16sRNA semiquantitative methods were used to detect the CRP expression and the relative contents of P. gingivalis, respectively.</p><p><b>RESULTS</b>Immunohistochemical results showed that the CRP-positive expression in groups B and C was significantly higher than that in group A (P<0.05). The CRP-positive expression in other group C rats were significantly lower than that in group C1 (P<0.05). The CRP-positive expression in group C2-2 was the lowest among the groups (P<0.05). The relative quantity of P. gingivalis in group C1 was the highest and significantly higher than that in groups A and B (P<0.05). The relative quantities of P. gingivalis in groups C2-1, C2-2, C3-1, and C3-2 were significantly lower than that in group C1 (P<0.05), and the quantity in group C3-2 was the lowest (P<0.05).</p><p><b>CONCLUSIONS</b>Rats with CP associated with HL will increase the CRP expression and oral bacteria quantity on carotid artery, and lesions will gradually aggravate. Interventions, such as periodontal basic treatment and tooth extraction, could improve carotid artery lesions. The basic treatment with local and systemic anti-inflammatory drugs exerts the most satisfactory effect on local CRP expression. Tooth extraction with antibiotics is an effective method on reducing oral bacteria in carotid artery. Periodontal basic treatment associated with local and systemic antiflammatory drugs can obviously improve the effect.

RESUMO

OBJECTIVE:To observe the efficacy and safety of Huanglian shangqing soft capsule in the adjuvant treatment of in-flammation around the implant. METHODS:40 patients(72 implants)with inflammation around the implant were randomly divid-ed into control group (20 cases) and observation group (20 cases). Control group received full mouth supragingival scaling tech-nique,subgingival curettage,root planing,occlusal adjustment,loose teeth fixation or removal can not be reserved teeth using ul-trasonic scaler row scaling postoperative with 3% hydrogen peroxide,0.9% Sodium chloride injection alternately flushing periodon-tal pocket,removing residue until the inflammation control after the break-adjusted+appropriate amount of Minocycline hydrochlo-ride ointment,along with fine needles inserted into the periodontal pocket wall slowly until bag after pushed into the bottom of Mi-nocycline hydrochloride ointment,slow retreated the drug overflow until the gingival margin,no gargle and drinking water within half an hour,once a week. Observation group additionally received 1.2 g Huanglian shangqing soft capsules,twice a day. 4-week was regarded as 1 course,and it last 2 courses. Clinical efficacy,PLI,PD,SBI,IL-1β,IL-6,IL-2 and IL-17 levels before and af-ter treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant (P<0.05). After treatment,the PLI, PD,SBI,IL-1β,IL-6,IL-2 and IL-17 levels in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). The incidence of adverse reactions in observation group was significantly higher than control group,the difference was statistically significant (P<0.05),but the symptoms were mild. CONCLUSIONS:Based on conventional treatment,Huanglian shangqing soft capsule shows significant efficacy in the adjuvant treatment of inflammation around the implant,it can reduce inflammatory cytokine levels in gingival sulcus fluid,but with more ad-verse reactions.
