ABSTRACT
OBJECTIVE:To study the inhibition effects of tranilast on hypertrophic scar tissue of rabbits and its mechanism. METHODS:Rabbits were selected to induce hypertrophic scar(HS)model,the HS model rats were randomly divided into model control group (normal saline),tranilast low-dose,medium-dose,high-dose groups (0.3,0.5,0.7 mg/kg),6 rabbits in each group,local intradermaly injected corresponding drugs. Scar thickness 1 h before injection and the first,third,fifth week after in-jection in each group were measured,pathological changes of scar(fifth week after injection)were observed,transforming growth factor β1 (TGF-β1),α-smooth muscle actin(α-SMA)mRNA and protein expression were detected. RESULTS:Compared with 1 h before injection,scar thickness of rabbits in other groups were decreased after injection except for model control group. In fifth week after injection,compared with model control group,scar thickness of rabbits in other groups were decreased,pathological changes were improved;TGF-β1,α-SMA mRNA and protein expression were decreased (P<0.05),showing positive correlation with tranilast dose. CONCLUSIONS:Tranilast can inhibit the formation of hypertrophic scar,and the mechanism may be related to inhibiting the TGF-β1,α-SMA mRNA and protein expression.
ABSTRACT
Professor HE Tianyou's unique understanding and treatment characteristics for intractahle facial paralysis are introduced. In clinical practice professor HE highly values acupoint selection and manipulation application, and integrates Chinese and western medicine to flexibly choose acupoints and formulate prescriptions according to syndrome differentiation and location differentiation, besides, he creates several specialized manipulation methods including "tug-of war opposite acupuncture method" and "tractive flash cupping". Based on strengthening body and dredging collaterals. more attention is given on stimulation to local paralyzed facial nerves; meanwhile acupuncture and medication are combined to improve clinical efficacy. During the treatment, the important role of psychological counseling on patient's anxiety is emphasized, and comprehensive treatment is given physically and psychologically in order to achieve the purpose of total rehabilitation.

Objective The aim of this study was to assess the relationship between the oral health habit and halitosis. It can provide an advisory basis for nurse giving individualized oral health instruction to patients of halitosis and can improve the result of prevention and treatment for halitosis accordingly. Methods 202 patients with periodontal disease were chosen to participate in this study. The study included the questionnaire of oral health habit and the halitosis diagnosis by organoleptic assessment.Comparisons of difference in the knowledge of oral health habit between the subjects with and without halitosis were conducted. Results Brushing times in subjects without halitosis were significantly more than that in subjects with halitosis. Brushing teeth in evening and interproximal brush usage were much better in subjects without halitosis than that in subjects with halitosis,respectively. Conclusions Good oral health habits could decrease the incidence of halitosis.
ABSTRACT
Objective To determine the effect of individualized oral hygiene instruction (OHI) on volatile sulfur compounds (VSCs) level in mouth air of patients with chronic periodontitis.Methods The individualized oral hygiene instruction was provided for 31 patients with chronic periedontitis (Organoleptic score was over two points).The VSCs and plaque index (PLI) were evaluated pre-OHI and post-OHI.Results The score of PLI decreased from 3.09±0.44 to 2.63±0.46 significandy (P<0.05).The organoleptic score (OS) decreased from 2.68±0.70 to 2.35±0.75 significandy (P<0.05).While there was no significant difference on the VSCs level pre-OHI and post-OHI (P<0.05).Conclusions Individualized oral hygiene instruction is helpful to remove plaque and improve oral hygiene.But the effect of OHI on VSCs level in mouth air is limited.
