以氧化石墨烯(GO)为固定酶载体,在水溶液中通过静电吸附及氢键作用实现溶菌酶(Ly)的固定化得到GO-Ly。并将已固定化酶的GO为添加剂,以聚醚砜为膜材料,采用相转化法制备杂化超滤膜。考察了添加剂含量对膜形态、亲水性、分离性能、力学性能及抗菌性能的影响。结果表明,GO-Ly 的加入使杂化膜的亲水性及纯水通量得到明显提高,同时拉伸强度也得到一定改善;尤其当GO-Ly 添加量为1.5 %(质量分数)时,膜的纯水通量达到318 L/(m2 · h),并且对聚乙烯醇(PVA 30 000~70 000)的截留率维持在99 %以上,对大肠杆菌的抑菌率可达68 %。

聚丙烯(polypropylene, PP)支架是目前最常用的生物医用支架,在外科手术使用中存在黏连、感染、异物反应等缺点。本文报道了一种简易一步法,用于制备新型三氯生聚多巴胺聚丙烯(TPP)复合支架,从而有效地提高了PP支架的生物相容性和持续抗菌性。通过一步法绿色制造,具有广谱抗菌效果的三氯生在聚多巴胺形成过程中,在PP支架表面可以有效地与多巴胺发生相互作用。三氯生可从具有生物相容性的聚多巴胺表面涂层持续释放。利用三氯生(浓度为8 mg∙mL−1,即TPP-8)制备的5 mm × 5 mm的支架具备持续抗菌性,对最大菌液量为2 mL的大肠杆菌(E. coli)和5 mL的金黄色葡萄球菌(S. aureus)的持续抗菌时间超过15 d。本研究为长效抗菌医用生物材料的绿色制备提供了一个新的方向。

Self-etching adhesives: possible new pulp capping agents to vital pulp therapy

Pulp capping is one of the solving for keeping vital pulp in the case of dentin caries, reversible pulpitis or traumatic pulp exposure. The presence of bacteria on the cavity walls or in the pulp was the major factor that leads to the failure of pulp capping. Traditional pulp capping agent, calcium hydroxide, may not prevent microleakage. Self-etching system is a newly developed adhesive system, which could provide less microleakage and would not break down or dissolve, preventing the oral fluids and bacteria from the pulp along the cavity wall. This may reduce such clinical problems as postoperative sensitivity, secondary caries and marginal discoloration. Researches showed that some kinds of self-etching adhesives induced the mild to moderate inflammatory pulp response, with negative bacterial staining. Inclusion of antibacterial components into self-etching system, such as 12- methacryloyloxydodecylpyridinium bromide (MDPB) may inhibit bacteria and provide better clinical effects. It is speculated that using the self-etching adhesive system containing the antibacterial agent, such as MDPB, to the dental pulp directly or indirectly, may inhibit bacteria after the placement of restoration as well as residual bacteria in the cavity.

Pursh (PCP) is a popular traditional medicinal plant in China, widely used for the treatment of a variety of liver diseases. Although it has been long recognized that the main active elements of PCP are contained in ethyl acetate fraction (EAF), little is known so far in terms of the relative effectiveness of EAF derived from the stems versus leaves of this plant. In the current study, we prepared EAF by reflux extraction and sequential extraction from the stems (SEAF) and leaves (LEAF) of PCP and tested their hepatoprotective efficacies. The extract rates and flavonoid contents of LEAF were higher than those of SEAF. EAFs (>50 μg·mL ) prevented lipid accumulation in cells and protected against lipotoxicity injury when the concentration exceeded 25 μg·mL . More than 95% free radicals released by 2,2-diphenyl-1-picrylhydrazyl (DPPH) were eliminated by 25 μg·mL SEAF and 50 μg·mL LEAF, respectively. Further, EAFs (25 μg·mL ) also showed protective antioxidant effects, with the activity of LEAF being significantly higher than that of SEAF. EAFs (10 mg·mL ) also showed similar unspecific bacteriostatic activity. In comparison with SEAF, LEAF contained more flavonoids and had a higher anti-oxidation capability and for these reasons we suggest it should be better for clinical use.
