[Effect of moxibustion combined with Guifu Yuhe decoction on the conversion score of idiopathic constitution, serum total lgE and blood EOS in the patients with allergic acne].

OBJECTIVE: To observe the therapeutic effect of moxibustion combined with Guifu Yuhe decoction on allergic acne and the influence on immunologic function in the patients. METHODS: A total of 60 patients with allergic acne were rando-mized into an observation group (30 cases) and a control group (30 cases).Thirty healthy employees were in the healthy group. In the control group, Guifu Yuhe decoction was prescribed for oral administration, while in the observation group, on the base of the treatment as the control group, moxibustion was exerted at Dazhui (GV14) and Shenque (GV8). The treatment duration was 8 weeks. Before and after treatment, serum IgE, blood EOS, CD4+T cell, CD8+ T cell and CD4+T/CD8+T, as well as the conversion score of idiopathic constitution and the symptom score were compared in the patients of two groups. The clinical therapeutic effect was observed in the two groups. RESULTS: Before treatment, compared with the healthy group, IgE and EOS, CD4+T cell and CD8+T cell all increased (P<0.05), and CD4+T/CD8+T decreased in the two groups (P<0.05). After treatment, IgE, EOS and CD4+T cell and CD8+T cell decreased (P<0.05), and CD4+T/CD8+T increased (P<0.05) in the intra-group comparison in the patients. The changes of IgE, EOS, CD4+T cell and CD8+T cell in the observation group were more larger than those in the control group (P<0.05). After treatment, the conversion score of body constitution and symptom score all decreased in either group (P<0.05) and the scores in the observation group were lower than those of the control group (P< 0.05). The total effective rate of the observation group (29/30, 96.7%) was higher than that of the control group (22/30, 73.3%, P<0.05). CONCLUSION: Moxibustion combined with Guifu Yuhe decoction can significantly improve immune function and body constitution of the patients with allergic acne, which may be related to rectifying idiopathic constitution, improving in lymphocyte subsets dysfunction and inhibiting allergic reaction.

Properties of Rigid Polyurethane Foam Modified by Tung Oil-Based Polyol and Flame-Retardant Particles.

Although tung oil is renewable, with an abundant production and low price in China, and it is used to synthesize different polyols for rigid polyurethane foam (RPUF), it remains a challenge to improve the properties of RPUF by redesigning the formula. Therefore, we propose four novel compounds to strengthen the properties of RPUF, such as the catalyst-free synthesis of tung oil-based polyol (PTOK), aluminum phosphate micro-capsule (AM), silica micro-capsule (SiM), and grafted epoxidized monoglyceride of tung oil on the surface of SiO2 (SiE), which were designed and introduced into the RPUF. Because of the PTOK with a catalytic function, the foaming process of some RPUF samples was catalyst-free. The results show that the incorporation of AM, SiM, and SiE, respectively, endow RPUF with a better thermal stability at a high temperature, and the T5%, Tmax1, and Tmax2 of RPUF appeared to be reduced, however, the Tmax3 and residue rate at 800 °C were improved, which may have a positive effect on the extension of the rescue time in case of fire, and the limiting oxygen index (LOI) value was increased to 22.6%. The formula, containing 25% PTOK made the RPUF environment-friendly. The results were obtained by comparing the pore size and mechanical properties of the RPUF-the AM had a better dispersion in the foam, and the foam obtained a better mechanical, thermal, and flame retardancy.
