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。     

Aging attenuates the ovarian circadian rhythm

ObjectiveTo study the effect of aging on ovarian circadian rhythm.DesignHuman and animal study.SettingUniversity hospital and research laboratory.Patients/animalsHuman granulosa cells were obtained by follicular aspiration from women undergoing in vitro fertilization (IVF), and ovarian and liver tissues were obtained from female C57BL/6 mice.Intervention(s)None.Main outcome measure(s)Expression of circadian genes in young and older human granulosa cells and circadian rhythm in ovaries and livers of young and older mice.Result(s)All examined circadian clock genes in human granulosa cells showed a downward trend in expression with aging, and their mRNA expression levels were negatively correlated with age (P < 0.05). Older patients (≥ 40 years of age) had significantly reduced serum anti-Müllerian hormone (AMH) levels. Except for Rev-erbα, all other examined circadian clock genes were positively correlated with the level of AMH (P < 0.05). The circadian rhythm in the ovaries of older mice (8 months) was changed significantly relative to that in ovaries of young mice (12 weeks), although the circadian rhythm in the livers of older mice was basically consistent with that of young mice.Conclusion(s)Lower ovarian reserve in older women is partially due to ovarian circadian dysrhythmia as a result of aging.Electronic supplementary materialThe online version of this article (10.1007/s10815-020-01943-y) contains supplementary material, which is available to authorized users.     

Metastasis of oral squamous cell carcinoma to the parotid lymph nodes

Parotid lymph node (PLN) metastasis greatly worsens the prognosis of patients with oral squamous cell carcinoma (OSCC) and poses a great challenge for further treatment of OSCC. The clinicopathological characteristics and treatment strategies for PLN metastasis from OSCC need to be comprehensively elucidated. A retrospective review of OSCC patients who experienced postoperative PLN metastasis in our department between 2000 and 2018 was performed in this study. A total of 47 OSCC patients with postoperative PLN metastasis were identified. PLN with metastasis were divided into three groups based on the location: parotid tail (PLN-t), superficial lobe (PLN-sl), and deep lobe (PLN-dl). Most of the patients experienced PLN metastasis within less than 12 months after the primary surgery for OSCC. Comparatively, patients with PLN-sl metastasis were more prone to have infiltration of the facial nerve. The tongue and buccal mucosa were the most frequent primary sites associated with PLN metastasis from OSCC. PLNs in the parotid tail were most commonly affected by the metastasized OSCC. Consequently, we recommend a series of strategies for the prevention and treatment of PLN metastasis for OSCC patients. In conclusion, PLNs should not be overlooked during preoperative evaluation and postoperative follow-up examinations for OSCC patients.     

Thinned-out skin paddle versus collagen matrix as an optimized peri-implant soft tissue following fibula osteoseptocutaneous free flap: 3-year retrospective study

The objective of this study was to compare the implant longevity following two methods of peri-implant soft tissue optimization following free fibula flap (FFF): thinning of skin paddle (SP) and collagen matrix (CM). All patients who underwent rehabilitation with dental implants after mandibular reconstruction with FFF between June 2009 to May 2014 were retrospectively reviewed. Two methods of peri-implant soft tissue optimization were applied: (1) SP group, (2) CM group. Outcome measurements were: modified plaque index (mPI), modified sulcus bleeding index (mSBI), probing depth (PD), marginal bone loss (MBL), implant success rate and complication rates. A total of 24 patients with 69 implants were included in the study, with 8.7% (n = 6) of implants lost in 3 years. No statistically significant difference was found regarding the outcome measurements in both groups. Failed implants presented with statistically significant higher mPI, mSBI, PD and MBL scores during prosthesis delivery and subsequent follow-ups (P<0.03). In the SP group, one patient experienced SP necrosis which later underwent soft tissue optimization using CM. CM is an alternative peri-implant soft tissue, while thinning of SP is feasible if thickness is well controlled.     

芦山地震5年后雅安市高血压患者心理卫生问题检出率及其影响因素

目的 了解芦山地震5年后雅安市高血压患者心理卫生问题检出率及其影响因素，为促进地震灾区高血压患者心理健康提供参考。方法 采用分层整群随机抽样方法，于2018年12月选取雅安市高血压患者800例作为研究对象。采用自编居民基本信息调查表收集患者的基本资料，采用12项一般健康问卷（GHQ-12）评定患者近期是否存在心理卫生问题，采用Logistic回归分析其影响因素。结果 回收有效问卷744份（93.00%），检出存在心理卫生问题者79例（10.62%）。单因素分析结果显示，不同婚姻状况（P?0.01）、家庭人均月收入（P=0.012）、是否接受社会救助（χ²=25.194，P?0.01）的高血压患者心理卫生问题检出率差异均有统计学意义。Logistic回归分析显示，未婚/分居/离异/丧偶（OR=3.879，P=0.015）以及接受社会救助（OR=4.705，P?0.01）是高血压患者存在心理卫生问题的危险因素。结论 雅安市高血压患者心理卫生问题检出率较低，未婚/分居/离异/丧偶者以及接受社会救助的高血压患者心理卫生问题可能更突出。
