前人总结的用药禁忌十八反未必是绝对禁忌,笔者从广东省名中医陈国成主任独创星夏止痛膏外治中得到反药“乌头-半夏”的配伍启示。本文简要叙述反药配伍的源流及应用,重点对陈国成使用乌头配半夏外用的经验及思路进行论述,认为乌头与半夏配伍可通过多种方式减毒增效,为临床安全使用该配伍药物提供新的思路。
The eighteen antagonisms summarized by predecessors may not be absolute contraindications.The author obtained the inspiration of the antagonism medicinals “aconite-pinellia” from the external treatment of Xingxia painkiller ointment created by Chen Guocheng.The present paper provides a concise overview of the origin and application of anti-drug compatibility,with a specific focus on Chen Guocheng's expertise and insights regarding the external use of aconite combined with pinellia.It is postulated that diverse approaches can be employed to modulate the compatibility between aconite and pinellia,thereby offering novel perspectives for ensuring the safe utilization of this drug combination in clinical practice.

目的 探讨制何首乌、巴戟天及二者配伍,对氧化型低密度脂蛋白(ox-LDL)诱导的人脐静脉内皮细胞(HUVEC)损伤的影响,以示临床。方法 建立ox-LDL诱导的HUVEC损伤模型,分别用制何首乌、巴戟天、二者配伍的水煮物干预,检测HUVEC的细胞增殖、相对活率、细胞凋亡率、细胞周期、NFκB mRNA的表达。结果 ①制何首乌、巴戟天均能抑制ox-LDL诱导的HUVEC凋亡,二者配伍的抑制作用强于单味中药制何首乌。②制何首乌、巴戟天均能延长ox-LDL诱导的HUVEC的细胞周期(S+G2)%,制何首乌、巴戟天的延长作用相似,二者配伍的延长作用强于单味中药制何首乌、巴戟天。③制何首乌组、巴戟天组的NFκB mRNA的表达量下降,制何首乌组的抑制作用强于巴戟天组,二者配伍的抑制作用强于单味中药制何首乌、巴戟天。结果 制何首乌、巴戟天均能抑制ox-LDL诱导的HUVEC损伤,二者配伍的作用强于单味中药制何首乌、巴戟天。
Objective To investigate the effects of Polygonum multiflorum praeparata, Morinda officinalis and their compatibility on ox-LDL-induced injury of human umbilical vein endothelial cells(HUVEC). Methods We established an ox-LDL-induced HUVEC injury model, made intervention with Polygonum multiflorumpraeparata, Morinda officinalis and their compatibility, the HUVEC cell proliferation, relative viability, apoptosis, cell cycle, NFκB mRNA were detected. Results ①Both Polygonum multiflorumpraeparata, Morinda officinalis reduced the apoptosis rate of HUVEC, and their compatibility had a stronger effect on reducing the apoptosis rate of HUVEC than single Polygonum multiflorumpraeparata. ②Both Polygonum multiflorumpraeparata, Morinda officinalis increased the HUVEC cell cycle (S+G2)%, the extension between Polygonum multiflorumpraeparata and Morinda officinalis was similar, and their compatibility increased HUVEC cell cycle (S+G2)%, it was stronger than single Polygonum multiflorumpraeparata and single Morinda officinalis. ③Both Polygonum multiflorumpraeparata and Morinda officinalis down-regulated the expression of NFκB mRNA in HUVEC, their compatibility down-regulated HUVEC NFκB mRNA expression,it was stronger than Polygonum multiflorumpraeparata, Morinda officinalis. Conclusion Polygonum multiflorumpraeparata, Morinda officinalis and their compatibility can inhibit ox-LDL-induced HUVEC injury, and their compatibility inhibition is stronger than single Polygonum multiflorumpraeparata, and Morinda officinalis.

目的 体外构建胶原—壳聚糖复合支架材料,分析其物理化学性质及生物相容性,探讨其应用于组织工程支架材料的可行性。方法 利用冷冻干燥的方法构建三维多孔的胶原支架材料,通过甲醛交联以及添加壳聚糖的方法改善其物理化学性能。通过体外降解实验以及电镜扫描的方法检测材料的各项物理化学指标;通过细胞接种的方法研究材料的生物相容性。结果 胶原—壳聚糖复合材料通过冷冻干燥的方法,能够获得稳定的三维多孔结构,电镜显示孔隙贯通,体外降解速度降低,并且能够支持细胞生长。理化性质分析显示该结构适合细胞生长,具有良好的生物相容性。结论 本课题体外构建胶原—壳聚糖复合支架材料,满足组织工程生物材料的理化以及生物相容性要求,为其应用于组织工程支架材料提供重要的依据。
Objective We build up the Collagen-Chitosan compound scaffold in vitro,and study the physical,chemical and biological properties,to analyze the feasibility in tissue engineering. Methods The three-dimensional porous scaffold was obtained by freezing-drying method,and optimized by using formaldehyde and Chitosan.We used hydrolysis in vitro and SEM scanning to investigate its physical and chemical properties.The biocompatibility of scaffold was analyzed in MEF cells. Results Collagen-Chitosan compound scaffold we obtained by freezing-drying method was a kind of stable 3D vesicular structure.The scaffold degenerated in decreased velocity in vitro.The physical and chemical properties showed that it was suitable for the cells grow in it,which suggested that it has a good biocompatibility. Conclusion This kind of Collagen-Chitosan compound scaffold is constructed.It's qualified by the physical and chemical properties,and biocompatibility which the biomaterials require.The evidence are important for its application in tissue engineering.
