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。

弯刀综合征14例外科治疗结果分析

目的 探讨小儿弯刀综合征的诊断、外科治疗方法及治疗后的近、中期结果。方法 回顾性分析2010年1月到2017年12月手术治疗的14例弯刀综合征的临床资料。其中,男7例,女7例;年龄(18.23±28.55)个月,范围在23 d至9岁。合并其他心血管畸形10例,中位心8例,右肺发育不良7例,有侧支循环8例,合并肺动脉高压10例。用SPSS 16.0软件的寿命表(Life Table)做出本组患儿术后生存曲线,评估其近、中期生存状况。结果 9例异常肺静脉(scimitar vein,SV)从下腔静脉切下,端-侧吻合于左心房;SV分成2支2例,1例采用2支SV连同部分下腔静脉壁切下,另1例2支SV从下腔静脉从根部切下侧-侧吻合形成单根SV,均吻合于左心房;SV离左心房距离过大3例,2例将SV吻合在右心房右侧壁,再重建心房间隔,1例SV与自体心包卷管道连接再吻合于左心房。其他心血管畸形同期手术矫治。8例有侧支循环,3例心导管检查时被封堵,5例手术时切断缝合。本组14例手术死亡2例(14.29%),另有1例于术后1年2个月因肺炎、呼吸衰竭死亡。本组术后1、3、5年累积生存率分别为86%、73%和73%。术后出院时有1例移植的SV开口狭窄,血流速度为1.9 m/s;有3例随访期间发现移植SV狭窄,血流速度超过1.6 m/s。结论 弯刀综合征可合并其他心血管畸形、中位心、右肺发育不良等。一般将SV与左心房吻合;SV离左心房距离大或多条SV时,可采用个性化办法将SV吻合于左心房。侧支循环心导管检查时可封堵,或术中切断缝合。

Association of PD-L1 gene rs4143815 C>G polymorphism and human cancer susceptibility: A systematic review and meta-analysis

Programmed death ligand 1(PD-L1) mediated immune escape play important roles in the development of cancer. The gene polymorphism of PD-L1, in particular rs4143815 C?>?G, has been associated with the cancer risks, but with conflicting results. Therefore, this meta-analysis was aimed to assess the association between rs4143815 C?>?G and cancer susceptibility. A systematic literature search was performed to select the studies and the pooled odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the strength of association. Eleven eligible studies containing 3711 cases and 3704 controls were enrolled in the meta-analysis. The results suggested that there is a strong association between rs4143815 C?>?G and the cancer risks (G vs. C: OR?=?1.386, 95% CI: 1.132–1.696, p?=?0.002; GG vs. CG?+?CC: OR?=?1.843 95% CI: 1.300–2.613, p?=?0.002; GG?+?CG vs. CC: OR?=?1.280, 95% CI: 1.040–1.576, p?=?0.020). Subgroup analysis based on cancer type suggested that PD-L1 rs4143815 C?>?G might increase the susceptibility to gastric cancer (G vs. C: OR?=?1.842, 95% CI: 1.403–2.418, p?<?0.001) and bladder cancer (G vs. C: OR?=?2.015, 95% CI: 1.556–2.608, p?<?0.001), and genotype GG carriers of PD-L1 rs4143815 C?>?G might have higher risks of HCC (GG vs. CG?+?CC: OR?=?2.226 95% CI: 1.562–3.172, p?<?0.001). PD-L1 rs4143815 C?>?G might confer an increased cancer risk, indicating this SNP may contribute to the pathogenesis of cancer and might be used as a potential biomarker to predict the susceptibility to cancer.
