Resistance to Ultraviolet Aging of Nano-SiO2 and Rubber Powder Compound Modified Asphalt

Ultraviolet (UV) aging degrades the life span of asphalt pavement, nanomaterials used as modifiers exhibit good shielding function on UV light, but generally degrade the low-temperature property of asphalt, a compound modification was found to be a solution. In this study, nano-SiO₂ and rubber powder were blended together with base asphalt to prepare compound modified asphalt. Compound modified asphalt with different blending dosages were subjected to UV light via a self-made UV aging simulation chamber. Basic performance tests and rheological tests were conducted including the UV aging influence. An optimum compound ratio was finally recommended based on the goal to remove the adverse effect of nano-SiO₂ on the thermal cracking. Results show that the anti-UV aging property of asphalt is improved obviously due to the blocking function of nano-SiO₂ and carbon black in rubber powder, and the enhancing effect of nano-SiO₂ is found to be the most significant.

Effect of Compound Laser Acupuncture-Moxibustion on Blood Glucose, Fasting Insulin and Blood Lipids Levels in Type 2 Diabetic Rats

Objective: To investigate the effect of compound laser acupuncture-moxibustion on blood glucose, fasting insulin and blood lipids levels in type 2 diabetes mellitus(T2DM) rats. Methods: Forty male Wistar rats were randomly divided into 4 groups, including the normal group, model control group, laser group and sham laser group(n=10 per group). The rats in the normal group were fed with a standard diet. Rats in other groups were fed with a high-sugar and high-fat diet for 4 weeks, then intraperitoneally injected with 1% streptozotocin to induce T2 DM model. The laser group was irradiated by 10.6 μm and 650 nm compound laser on bilateral Pishu(BL 20), Shenshu(BL 23) and Sanyinjiao(SP 6) for 5 min, 6 times a week for 5 weeks. The sham laser group received the same treatment as the laser group, but without laser output. The model control group and normal group were not treated. Blood glucose levels were measured before and after 1, 2, 3, 4 and 5 weeks of treatment. The serum levels of fasting insulin, total cholesterol(TC), triglyceride(TG), low-density lipoprotein(LDL), and high-density lipoprotein(HDL) were analyzed after the last treatment. Results: The blood glucose levels in the model control group increased during the 5 weeks of treatment compared with the normal group(P0.05), while those in the laser group were significantly lower than the model control group after weekly treatment(P0.01 or P0.05). After 1, 2 and 3 weeks of treatment, the blood glucose levels in the laser group decreased obviously compared with the sham laser group(P0.01 or P0.05). Compared with the normal group, the levels of fasting insulin, TC and LDL in the model control group notably increased(P0.01 or P0.05), while their levels in the laser group were significantly lower than the model control group after 5 weeks of treatment(P0.05 or P0.01). However, no statistically significant differences were observed in TG or HDL levels among the 4 groups(P0.05). Conclusion: The compound laser acupuncture-moxibustion of 10.6 μm and 650 nm had positive effects on the regulation of hyperglycemia and insulin resistance in T2 DM rats, which may be a potential treatment for T2 DM, and also provide an alternative to the traditional acupuncture and moxibustion therapy.     

两种脾气虚证模型大鼠临床证候特征的比较

目的对比研究复合因素法与利血平皮下注射法所致脾气虚证模型大鼠的临床证候特征。方法将30只雄性SD大鼠随机分为正常组、复合因素组及利血平组,分别采用两种方式造模后,通过一般体征指标及证候量化评分评价临床证候表现;旷场实验评价大鼠心理及自主活动;检测血清D-木糖含量判断消化吸收能力。结果与正常组相比,两模型组大鼠证候量化评分总积分及各单项均升高(P<0.05,P<0.001),且利血平组各个单项及总积分均高于复合因素组(P<0.05);两组大鼠自主活动均较正常组减少(P<0.05);与复合因素组相比,利血平组穿格次数、中央区停留时间、活动距离下降尤为明显(P<0.001);与正常组相比,两组大鼠血清D-木糖含量均下降(P<0.01),两模型组之间差异无统计学意义(P>0.05)。结论两种造模方式都可造成大鼠脾气虚证候,但其临床证候表现有所不同,实验时应结合需求进行选择。
