Phytochemical interventions for post-traumatic stress disorder:A cluster co-occurrence network analysis using CiteSpace

Objective:This study investigated trends in the study of phytochemical treatment of post-traumatic stress disorder(PTSD).Methods:The Web of Science database(2007-2022)was searched using the search terms“phytochemicals”and“PTSD,”and relevant literature was compiled.Network clustering co-occurrence analysis and qualitative narrative review were conducted.Results:Three hundred and one articles were included in the analysis of published research,which has surged since 2015 with nearly half of all relevant articles coming from North America.The category is dominated by neuroscience and neurology,with two journals,Addictive Behaviors and Drug and Alcohol Dependence,publishing the greatest number of papers on these topics.Most studies focused on psychedelic intervention for PTSD.Three timelines show an“ebb and flow”phenomenon between“substance use/marijuana abuse”and“psychedelic medicine/medicinal cannabis.”Other phytochemicals account for a small proportion of the research and focus on topics like neurosteroid turnover,serotonin levels,and brain-derived neurotrophic factor expression.Conclusion:Research on phytochemicals and PTSD is unevenly distributed across countries/regions,disciplines,and journals.Since 2015,the research paradigm shifted to constitute the mainstream of psychedelic research thus far,leading to the exploration of botanical active ingredients and molecular mechanisms.Other studies focus on anti-oxidative stress and anti-inflammation.

The correlation of the quantitative ultrasonography parameters with the liver cancer cell proliferation activity and intralesional angiogenesis

Objective:To study the correlation of the quantitative ultrasonography parameters with liver cancer cell proliferation activity and intralesional angiogenesis.Methods: A total of 46 patients with liver cancer who received surgical resection in Hancheng People's Hospital between June 2014 and March 2017 as well as 28 patients who received partial hepatectomy for abdominal trauma during the same period were selected, the patients with liver cancer received ultrasonography, and the quantitative parameters were calculated;the liver cancer tissue and adjacent tissue of patients with liver cancer as well as the normal liver tissue of patients with abdominal trauma were collected to determine the expression of proliferation genes, tumor suppressor genes and angiogenesis genes.Results:The IMAX of liver cancer tissue was significantly higher than that of adjacent tissue while the TTP, WT and mTT were significantly shorter than those of adjacent tissue;RNF180, Merlin, PICK1 and PTEN protein expression in liver cancer tissue and adjacent tissue were significantly lower than those in normal liver tissue, negatively correlated with the IMAX of liver cancer tissue, and positively correlated with the TTP, WT and mTT of liver cancer tissue;EphB4, SALL4, Cripto-1, VEGF, PDGF, EGFR and Ang-2 protein expression in liver cancer tissue and adjacent tissue were significantly higher than those in normal liver tissue, positively correlated with the IMAX of liver cancer tissue, and negatively correlated with the TTP, WT and mTT of liver cancer tissue. Conclusion: The changes in the quantitative parameters of liver cancer ultrasonography are valuable for evaluating the cell proliferation and angiogenesis.

甲烷生理盐水通过抗氧化、抗炎症和抗凋亡发挥对哮喘小鼠的保护作用（英文）

目的:研究通过腹腔注射甲烷生理盐水对哮喘动物模型的保护作用及其可能的机制。创新点:通常我们认为甲烷生理盐水对人体并不发挥生理性的影响,但近年来涌现出的研究发现甲烷生理盐水可以发挥对多种脏器缺血再灌注损伤的保护作用。我们采用卵清蛋白刺激的小鼠哮喘模型,发现腹腔注射甲烷生理盐水的方式可以发挥对哮喘小鼠的保护作用,减轻哮喘小鼠氧化应激指标,缓解炎症和凋亡水平。方法:通过卵清蛋白刺激诱导小鼠气道高反应性的方式建立小鼠哮喘模型,治疗组小鼠给予甲烷生理盐水腹腔注射。通过测量小鼠气道阻力指数(RI)和动态肺顺应性(Cdyn)来检测小鼠气道高反应性;通过苏木精-伊红染色法(H&E)检测小鼠肺组织形态学;对小鼠肺泡灌洗液进行细胞测量;通过酶联免疫吸附试验(ELISA)测定灌洗液和采集的血清中白介素4(IL-4)、IL-5、IL-13和肿瘤坏死因子(TNF-α);通过生物化学的方式检测氧化应激指标(如丙二醛(MDA)、超氧歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽还原酶(GSH)、髓过氧化物酶(MPO)和8羟基脱氧鸟苷(8-OHdG));通过蛋白免疫印迹实验、实时定量聚合酶链式反应(qRT-PCR)和生化检测试剂盒检测凋亡相关蛋白。结论:甲烷生理盐水可以改善哮喘小鼠的气道功能,减少肺组织中浸润的炎性细胞。其保护作用有可能是通过甲烷抗氧化、抗炎和抗凋亡的生物学特性发挥的。

巨噬细胞参与反复潜水引起的肺损伤

目的:探索反复潜水引起肺损伤的炎症机制以及吸入高浓度氢气(HCH)对这种损伤的治疗作用。创新点:本研究首次在小鼠体内建立并评估减压诱导肺损伤(DILI)模型;首次探索巨噬细胞在DILI中的作用;首次探索呼吸HCH对于DILI的治疗作用。方法:将雄性C57小鼠随机分为对照组、DILI组和HCH组。DILI组于600 k Pa压力下暴露60 min,连续3d。HCH组在减压处理后吸入HCH(66.7%H2+33.3%O2)干预。减压操作6 h后检测小鼠肺功能和小鼠肺干湿比,取小鼠肺组织固定进行苏木精-伊红染色,并取小鼠全血进行血细胞计数实验。取小鼠肺组织提取蛋白并提取血清,采用酶联免疫吸附测定(ELISA)检测炎症因子与趋化因子,并使用蛋白质免疫印迹(western blotting)试验测定小鼠肺内小鼠含生长因子样模体粘液样激素样受体(F4/80)、巨噬细胞甘露糖受体(CD206)和诱导型一氧化氮合酶(i NOS)的表达量。使用免疫组化检测小鼠肺组织切片内F4/80、CD206和i NOS的阳性细胞的比例。提取小鼠肺组织内总信使核糖核酸(m RNA),使用荧光实时定量聚合酶链反应测定极化标记蛋白CD206和i NOS以及炎症因子TNF-α和IL-10的基因表达量。结论:多次减压可导致肺水肿、组织结构破坏和肺功能下降,病变程度和减压次数有关,证明模型建立成功。DILI可以诱导肺内和循环炎症反应的激活,巨噬细胞可能向肺内迁移趋化并向不同亚型极化,极化后的巨噬细胞M1与M2分别参与炎症激活与炎症抑制的过程。吸入HCH可以显著改善小鼠肺损伤,降低肺内炎症反应,抑制巨噬细胞向M1亚型极化并促进其向M2亚型极化,从而证明吸入HCH对于DILI具有治疗作用。
