Analysis on internal mechanism of zedoary turmeric in treatment of liver cancer based on pharmacodynamic substances and pharmacodynamic groups

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The anti liver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its "pharmacodynamic group". By searching the research on the anti hepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an anti hepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an anti hepatoma role. Network pharmacological analysis showed that the core targets of the "pharmacodynamic group" for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and "pharmacodynamic group", it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and "pharmacodynamic group" in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and "pharmacodynamic group".     

五味子根茎叶果多糖对D-半乳糖致小鼠学习记忆障碍的影响

目的观察五味子根、茎、叶及果多糖对D-半乳糖所致小鼠学习记忆障碍的影响。方法将雄性ICR小鼠随机分为6组,即空白组、模型组、五味子根多糖组、茎多糖组、叶多糖组及果多糖组,分别给予蒸馏水及总糖含量为35mg/kg的根、茎、叶及果粗多糖灌胃,30min后除空白组皮下注射生理盐水外,其他组均皮下注射300mg/kg剂量D-半乳糖,每日1次,持续6周。通过避暗实验和Morris水迷宫实验评价改善学习记忆能力。结果在避暗穿梭实验中,与空白组比较,模型组小鼠避暗潜伏期显著缩短,避暗穿梭次数显著增加(P<0.01);与模型组比较,五味子根、茎和果多糖组小鼠避暗潜伏期显著延长,避暗穿梭次数显著减少(P<0.01)。Morris水迷宫实验中,与空白组比较,模型组小鼠空间探索潜伏期显著延长,目标象限停留时间显著缩短,穿越平台次数显著减少(P<0.01);与模型组比较,五味子根、茎及果多糖组小鼠空间探索潜伏期显著缩短(P<0.05,P<0.01);五味子茎及果多糖组小鼠目标象限停留时间显著延长(P<0.01),根及叶多糖组目标象限停留时间无统计学差异(P>0.05);五味子茎及果多糖组小鼠穿越平台次数显著增加(P<0.01)。结论五味子根、茎及果多糖对D-半乳糖所致鼠学习记忆障碍具有改善作用。

基于唾液SIgA免疫防御探讨开雍刺血法治疗喉源性咳嗽疗效机制

目的:基于唾液SIgA免疫防御功能观察开雍刺血法治疗喉源性咳嗽的临床疗效,探讨其免疫机制。为开雍刺血法治疗喉源性咳嗽提供依据。方法:采用随机数字表法分组,将符合条件的70例患者分为开雍刺血法组(治疗组)和苏黄止咳胶囊组(对照组),各35例。治疗组给予开雍刺血法治疗,7 d行1次治疗,2～3次为1个疗程。对照组给予苏黄止咳胶囊治疗,每日3次,每次3粒口服,疗程为21 d。观察并记录治疗前后临床症状和体征情况以及唾液SIgA的变化情况,并记录不良反应。结果:经统计学分析,治疗组和对照组治疗喉源性咳嗽均有效,且两组治疗后唾液SIgA高于治疗前,差异有统计学意义(P0.05),治疗组治疗前后唾液SIgA差值以及总有效率均优于对照组,差异有统计学意义(P0.05);治疗组治疗后症状体征总分以及各因子评分均低于治疗前,且明显优于对照组,差异有统计学意义(P0.05)。结论:开雍刺血法能快速显著缓解或消除喉源性咳嗽的症状,同时可以通过提高唾液SIgA的水平,提升患者免疫力,该方法治疗喉源性咳嗽安全有效。
