RESUMO
[Objective]To summarize Professor YANG Danhong's clinical experience in the treatment of pain.[Methods]Through learning from teacher,reviewing ancient books and modern literature research,based on the pathogenesis of pain,the theoretical basis of Professor YANG's meridian acupuncture method and its application prospect for the treatment of pain were discussed.Two clinical medical cases were cited to support.[Results]The mechanism of pain is"obstruction leads to pain"and"malnutrition leads to pain",mainly because the Qi mechanism does not run smoothly.Professor YANG believes that the treatment should be aimed at smoothing the Qi mechanism.Based on the theory of"Gen-Jie"and"Genliu Zhuru"in Huangdi Neijing,the meridian acupuncture method named"the meridian acupuncture method"are proposed for pain.It is also treated according to Professor YANG's own clinical experience and combining with the piercing method.The acupuncture method,which emphasizes the theory of the treatment based on the channel's differentiation of pain,takes the head and tail points of the meridians passed by the disease position.After quickly twisting and getting Qi,and the well points are blooded.The two medical cases attached were caused by obstruction of Qi mechanism.The treatment took the first and last points of the meridians through the meridian acupuncture method,so that Qi and blood could be carried out and the pain was cured.[Conclusion]Professor YANG pays attention to the theory of the treatment based on the channel's differentiation of pain,and emphasizes the combination of the first and last points and the well points.Cooperated with the pricking collaterals therapy to strengthen the circulation of Qi and regulating Qi and blood,the effect was quite good,which was worthy of clinical promotion.
RESUMO
BACKGROUND: Long-term use of flexible denture prosthesis will increase the incidence of caries and periodontal disease, and partial denture stomatitis. The addition of fluoride in the prosthesis material can prevent and reduce the incidence of these diseases. Currently, increasing research addresses the addition of fluoride into dental materials at home and abroad, but little is reported on the addition of sodium monofluorophosphate (Na2(PO3)F into flexible denture materials and on the relevant mechanical performance.OBJECTIVE: To evaluate the mechanical properties of flexible denture materials containing different fluoride concentrations.METHODS: Totally 180 elastic denture samples were made at the three different sizes of 80 mm×51 mm×1 mm (n=60), 20 mm×5 mm×5 mm (n=60), 25 mm×2 mm×2 mm (n=60). Then, elastic denture samples containing Na2(PO3)F 0 (control), 3%, 5%, 10%, 15%, 20% were prepared in each size groups. The tensile strength, flexural strength and Shore A hardness of the samples were tested.RESULTS AND CONCLUSION: When the mass ratio of fluoride was up to 10%, the tensile strength and flexural strength reduced a little (P > 0.05). When the mass ratio of fluoride was up to 15%, the tensile strength and flexural strength were significantly lower than those of non-fluoride samples (P < 0.05). When the mass ratio of fluoride was up to 20%, the tensile strength, flexural strength and Shore A hardness were significantly lower than those of non-fluoride samples (P < 0.05). To conclude, Na2(PO3)F content has a significant effect on the tensile strength, flexural strength and Shore A hardness, and 10% is the best proportion of Na2(PO3)F. The mechanical properties of fluoride-containing flexible denture materials will be changed if the mass ratio of fluoride is higher than 10%.
