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".     

重组人促红细胞生成素在肝癌根治术患者异体输血中的应用观察

目的:观察肝癌根治术患者异体输血中应用重组人促红细胞生成素的临床疗效.方法:回顾性分析2020年1月至2021年12月期间我院收治的83例肝癌患者,根据治疗药物的不同将其分为对照组(n=38)和研究组(n=45),对照组采取常规治疗(琥珀酸亚铁),研究组患者在对照组基础上联合重组人促红细胞生成素治疗.比较两组术中失血量、输血量、血常规指标[红细胞(Red Blood Cell,RBC)、红细胞比容(hematocrit,Hct)、血红蛋白(Hemoglobin,HgB)]以及不良反应.结果:两组术中失血量无显著差异,但研究组术中输血量低于对照组(P＜0.05);治疗后两组患者RBC、Het、HgB均明显上升,其中研究组上升程度更为显著(P＜0.05);两组不良反应发生率无显著差异.结论:重组人促红细胞生成素可改善血常规指标,降低肝癌根治术患者术中异体输血量,值得临床应用推广.     

宣白承气汤联合西医常规治疗慢性阻塞性肺疾病急性加重期系统评价

目的系统评价宣白承气汤联合西医常规治疗慢性阻塞性肺疾病急性加重期(AECOPD)的临床疗效及安全性。方法计算机检索中国生物医学文献数据库(CBM)、中国知识资源总库(CNKI)、中国学术期刊数据库(万方数据)、中文科技期刊数据库(维普网)、Pub Med,纳入宣白承气汤及其加减联合西医常规治疗与单纯西医常规治疗比较治疗AECOPD的随机对照试验,采用Cochrane系统评价手册进行文献质量评价和数据提取,采用RevMan5.3对临床疗效指标进行Meta分析。结果纳入文献12篇,Meta分析结果显示:试验组总有效率高于对照组,差异有统计学意义[OR=4.83,95%CI(3.09,7.54),P0.000 01];试验组较对照组可显著降低中性粒细胞百分比、C反应蛋白等炎性指标和动脉血二氧化碳分压,显著提高第一秒用力呼气容积占预计值的百分比、用力肺活量占预计值的百分比、第1秒用力呼气容积/用力肺活量等肺功能指标和动脉血p H值、动脉血氧分压,差异均有统计学意义。纳入文献均未报道严重不良反应。结论宣白承气汤联合西医常规加减治疗AECOPD疗效显著,但由于纳入文献量和样本量较少,研究质量较低,其临床疗效与安全性仍需高质量的多中心、大样本、随机对照试验进一步验证。     

Transplantation of an eight-organ multivisceraI graft in a patient with frozen abdomen after complicated Crohn's disease

To report an extended multivisceral transplantation (MVTx) including right kidney and ascending colon in a patient with complicated Crohn's disease (CD). A 36-year old female suffering from short bowel syndrome and frozen abdomen due to fistulizing CD after multiple abdominal operations underwent MVTx of eight organs including stomach, pancreatoduodenal complex, liver, intestine, ascending colon, right kidney, right adrenal gland, and greater omentum in November 2003. Immunosuppression consisted of alemtuzumab, tacrolimus and steroids. The patient was off parenteral nutrition by postoperative wk 3. She experienced one episode of pneumonia. The patient recovered completely and discharged 2.5 mo and was doing well 30 mo after MVTx. This is one of the very rare cases in which a complete mulitivisceral graft of eight abdominal organs was transplanted orthotopically.     

Ligustrazine inhibits high voltage-gated Ca~(2+) and TTX-resistant Na~+ channels of primary sensory neuron and thermal nociception in the rat:a study on peripheral mechanism

Objective Ligustrazine, also named as tetramethylpyrazine, is a compound purified from Ligusticum chuanxiong hort and has ever been testified to be a calcium antagonist. The present investigation was to determine the antinoci-ceptive effect of ligustrazine and, if any, the peripheral ionic mechanism involved. Methods Paw withdrawal Latency ( PWL) to noxious heating was measured in vivo and whole-cell patch recording was performed on small dorsal root ganglion (DRG) neurons. Results Intraplantar injection of ligustrazine (0.5 mg in 25μl) significantly prolonged the withdrawal latency of ipsilateral hindpaw to noxious heating in the rat. Ligustrazine not only reversibly inhibited high-voltage gated calcium current of dorsal root ganglion (DRG) neuron in dose-dependent manner with IC50 of 1.89 mmol/L, but also decreased tetrodotoxin (TTX) -resistant sodium current in relatively selective and dose-dependent manner with IC50 of 2.49 mmol/L. Conclusion The results suggested that ligustrazine could elevate the threshold of thermal nociception through inhibiting the high-voltage gated calcium current and TTX-resistant sodium current of DRG neuron in the rat.
