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".     

钙离子通道蛋白TRPV6及其相关疾病的研究进展

瞬时受体电位亚家族V成员6 (Transient Receptor Potential Channel Subfamily V Member 6, TRPV6) 是一种钙离子高度选择性离子通道，在多种组织中均有表达，控制细胞顶端钙离子的进入，在维持钙稳态中发挥重要作用。TRPV6功能异常会影响体内钙稳态，进而引发新生儿骨骼发育异常、甲状旁腺功能亢进、骨与软骨代谢异常、肾结石和高尿钙症、 以及炎症性肠病和慢性胰腺炎等多种疾病。近年来研究也表明，TRPV6的上调与多种肿瘤的侵袭性增加有关，具有作为肿瘤检测的标志物以及治疗靶点的潜力。本综述将聚焦于TRPV6与其在相关疾病中发挥的作用，旨在为TRPV6作为药物靶点实现临床转化提供理论依据。

利用CNV-seq技术产前诊断Pallister-Killian综合征胎儿一例

应用拷贝数变异测序(copy number variation sequencing,CNV-seq)技术鉴别来源不明的胎儿标记染色体,明确其遗传物质的来源,并探讨此技术在产前诊断中的应用价值。讨论Pallister-Killian综合征(Pallister-Killian syndrome,PKS)的临床特征及遗传学特点,提高对此类罕见染色体疾病的认识。该病例因在妊娠中期超声发现胎儿异常而行羊水穿刺进行CNV-Seq检测,同时分析胎儿和父母的核型。羊水CNV-Seq结果示该样本12号染色体p13.33-p11.1处检测到拷贝数为3.5、片段大小为34.70 Mb的嵌合重复区域;羊水染色体核型结果为47,XY,+i(12)(p10)[58]/46,XX[42],综合上述结果考虑为PKS。通过结合超声结果,综合应用染色体G显带核型分析和CNV-seq技术能准确确认染色体异常片段来源,在产前有效诊断PKS患者。

清热解毒方辅助一次性根治术治疗小儿肛周脓肿临床研究

目的：观察清热解毒方辅助一次性根治术治疗小儿肛周脓肿的疗效及对肉芽组织生长的影响。方法：选取120 例肛周脓肿患儿，按随机数字表法分为对照组和观察组各60 例。对照组行一次性根治术治疗，观察组在对照组基础上术后加用清热解毒方坐浴治疗。比较2 组中医症状评分、渗液评分、视觉模拟评分法（VAS） 评分及肉芽组织生长评分，评价2 组临床疗效及不良反应发生情况。结果：观察组总有效率为91.67%，高于对照组73.33%，差异有统计学意义（P＜0.05）。治疗后，2 组肛门肿痛、夜寐不安、恶寒发热、溲赤便秘、舌红苔黄等中医症状评分较治疗前降低，且观察组各症状评分均低于对照组（P＜0.05）。治疗后，2 组渗液评分、VAS 评分均较治疗前降低，且观察组渗液评分、VAS 评分均低于对照组（P＜0.05）。治疗后，观察组创面愈合时间、腐肉脱落时间、肉芽组织生长评分均少于对照组，创面愈合度高于对照组（P＜0.05）。观察组不良反应发生率为6.67%，低于对照组20.00%，差异有统计学意义（P＜0.05）。结论：清热解毒方辅助一次性根治术治疗小儿肛周脓肿临床疗效显著，可有效改善患儿中医临床症状和肉芽组织生长情况，加快患儿伤口愈合，安全性较好。
