Compared with the Epoxy resorcinol-formaldehyde resin pretreatment system and Maleic anhydride pretreatment system developed by Xusigui, the 40% carbolated styrene-butadiene latex system can keep the composite"s properties and reduce the cost of pretreatment and simplify the pretreatment technology; especially to the HST 2073 latex system, the composite"s mechanics properties are improved greatly. Secondly, the composite"s comprehensive properties and interface performance are improved by reinforced with short fiber grafted with rubber in the surface. Thirdly, to simplify the production technology of composite, we add TKM-M and RF-90 as adhesive agent to the composite blended in an internal mixer, so as to the composite can be used to industry widely, then the effect of the amount adhesive agent on the composite"s properties and interface adhesive performance was studied, from the experiments the optimum amount of adhesive agent was deduced.

其中采用特软羧基丁苯胶乳预处理短纤维的方案，降低了预处理成本，相对许泗贵的低分子环氧和马来酸酐体系来说，预处理工艺大大简化了，而材料的力学性能保持良好，尤其是 HST 2073A 胶乳预处理体系，力学性能有较大幅度的提高；第二，通过对尼龙短纤维表面进行接枝橡胶分子链预处理，改善了复合材料的界面粘合性能，复合材料的综合性能也得到了相应的提高；第三，为了简化复合材料的生产工艺，使复合材料的应用得到工业化推广，我们选用TKM—M和RF—90长效增粘剂，直接加入短纤维橡胶复合材料中，采用密炼工艺，探讨了增粘剂的用量对复合材料界面粘合以及性能的影响，得出了增粘剂在复合材料中的最佳用量。

Objective: To study the curative effect and influence of serum IL-2 using riboflavine laurate on patients with recurrent oral ulcers.

目的：观察长效核黄素治疗复发性口腔溃疡的效果及对血清白细胞介素-2(IL-2)水平的影响。

Methods: 408 cases of mild recurrent oral ulcers were randomly divided into two groups: The patients in experiment group were treated with riboflavine laurate 150 mg one time a week, last three period and routine treatment, while the patients in contorl group received only routine treatment. Total effective rate and the level of IL-2 before and after treatment in two groups were contrasted.

408例轻型复发性口腔溃疡患者随机分为两组，对照组采用常规治疗，核黄素治疗组在常规治疗基础上一次性肌肉注射长效核黄素150mg，每周1次，共用3个周期，比较两组总有效率及治疗前、后IL-2水平。

Riboflavine laurate has definitely curative effect on treating recurrent oral ulcers and lower recurrence rate, which is worth spreading.

长效核黄素治疗复发性口腔溃疡，疗效确切，复发率降低，未见明显毒副作用，值得临床推广。

Levobupivacaine is a new , long-acting amide local anesthetic . The physicochemical properties and anaesthesia potence of LEVO and Bupivacaine appear similar . The central nervous system toxicity and cardiotoxicity of LEVO is less than that of BUPI. LEVO can be used extensively in clinic .
