    黄曲霉是最常见的黄曲霉毒素生产者。黄曲霉L菌株的非黄曲霉毒素成员在各个大洲用作生物保护剂的活性成分,旨在通过竞争性取代黄曲霉毒素生产者来防止黄曲霉毒素污染。当前的研究检查了整个南欧的A.flavusL菌株的遗传多样性,以了解该物种的种群结构和进化,并评估与AF-X1的活性成分MUCL54911密切相关的基因型的患病率。从整个希腊收集的玉米中回收的总共2173L菌株分离株,西班牙,和塞尔维亚在2020年和2021年进行了简单序列重复(SSR)基因分型。分析显示,国家内部和国家之间存在高度多样性,共有数十种单倍型。连锁不平衡分析表明,居住在欧洲的黄曲霉的无性繁殖和克隆进化。此外,发现与MUCL54911密切相关的单倍型属于相同的植物相容性组(VCG)IT006,并且在所有三个国家中相对常见。结果表明,IT006是南欧特有的,可以用作该地区玉米的黄曲霉毒素缓解工具,而不必担心与引入外来微生物相关的潜在不利影响。
    Aspergillus flavus is the most frequently identified producer of aflatoxins. Non-aflatoxigenic members of the A. flavus L strains are used in various continents as active ingredients of bioprotectants directed at preventing aflatoxin contamination by competitive displacement of aflatoxin producers. The current research examined the genetic diversity of A. flavus L strain across southern Europe to gain insights into the population structure and evolution of this species and to evaluate the prevalence of genotypes closely related to MUCL54911, the active ingredient of AF-X1. A total of 2173L strain isolates recovered from maize collected across Greece, Spain, and Serbia in 2020 and 2021 were subjected to simple sequence repeat (SSR) genotyping. The analysis revealed high diversity within and among countries and dozens of haplotypes shared. Linkage disequilibrium analysis indicated asexual reproduction and clonal evolution of A. flavus L strain resident in Europe. Moreover, haplotypes closely related to MUCL54911 were found to belong to the same vegetative compatibility group (VCG) IT006 and were relatively common in all three countries. The results indicate that IT006 is endemic to southern Europe and may be utilized as an aflatoxin mitigation tool for maize across the region without concern for potential adverse impacts associated with the introduction of an exotic microorganism.

    新生儿疾病正面临严重的公共卫生挑战。以前的研究基于有限的数据源,地理范围狭窄。我们的目标是了解从1990年到2019年,204个国家和地区新生儿疾病负担的变化趋势。
    数据来自2019年全球疾病负担研究。首先,我们使用病例数和年龄标准化发病率(ASIR)可视化新生儿疾病的负担,死亡率(ASDR),和1990年至2019年的残疾调整寿命年(ASR-DALYs)。第二,估计的年度百分比变化(EAPC)用于评估不同时期疾病负担的时间趋势。最后,社会人口指数(SDI)和人类发展指数(HDI)用于确定社会经济发展水平之间是否存在相关性,人类发展水平,和潜在的负担后果。
    总的来说,在过去的30年里,ASIR趋势保持相对稳定,而ASDR和ASR-DALYs有所下降。然而,新生儿疾病的负担在不同地区和国家差异很大。在21个地区中,ASIR趋势在拉丁美洲中部增加最大(EAPC=0.42,95CI=0.33-0.50).相反,ASDR和ASR-DALYs在中欧(EAPC=-5.10,95CI=-5.28至4.93)和东亚(EAPC=-4.07,95CI=-4.41至3.73)下降幅度最大,分别。在204个国家中,希腊的ASIR(EAPC=3.35,95CI=3.13-3.56)趋势显示出最显著的增长,而多米尼加的ASDR(EAPC=1.26,95CI=1.01-1.50)和ASR-DALYs(EAPC=1.26,95CI=1.03-1.49)趋势增长最为显著.此外,ASIR中的EAPC之间有很强的相关性,ASDR,ASR-DALYs,以及2019年的SDI或HDI,但有一些例外。此外,HDI水平升高的国家,新生儿疾病的ASDR和ASR-DALYs增加较快.
    尽管从1990年到2019年,新生儿疾病的负担呈下降趋势,但仍然不容乐观。有必要采取多管齐下的方法来减轻新生儿疾病日益增加的负担。
    Neonatal disorders are facing serious public health challenges. Previous studies were based on limited data sources and had a narrow geographical scope. We aim to understand the trends of alteration in the burden of neonatal disorders from 1990 to 2019 in 204 countries and territories.
    Data were investigated from the Global Burden of Disease Study 2019. First, we visualized the burden of neonatal disorders using the number of cases and the age-standardized incidence rate (ASIR), death rate (ASDR), and disability-adjusted life years (ASR-DALYs) from 1990 to 2019. Second, estimated annual percentage changes (EAPCs) were used to evaluate the temporal trends of disease burden during different periods. Finally, the sociodemographic index (SDI) and human development index (HDI) were used to determine whether there exists a correlation between socioeconomic development level, human development level, and potential burden consequences.
    Overall, in the past 30 years, the ASIR trends have remained relatively steady, whereas the ASDR and ASR-DALYs have declined. However, the burden of neonatal disorders varied greatly in various regions and countries. Among 21 regions, the ASIR trend had the largest increase in Central Latin America (EAPC = 0.42, 95%CI = 0.33-0.50). Conversely, the ASDR and ASR-DALYs experienced the largest decrease in Central Europe (EAPC = -5.10, 95%CI = -5.28 to 4.93) and East Asia (EAPC = -4.07, 95%CI = -4.41 to 3.73), respectively. Among 204 countries, the ASIR (EAPC = 3.35, 95%CI = 3.13-3.56) trend in Greece displayed the most significant increase, while the ASDR (EAPC = 1.26, 95%CI = 1.01-1.50) and ASR-DALYs (EAPC = 1.26, 95%CI = 1.03-1.49) trends in Dominica experienced the most substantial increase. Furthermore, there was a strong correlation between the EAPCs in ASIR, ASDR, ASR-DALYs, and SDI or HDI in 2019, with some exceptions. In addition, countries with elevated levels of HDI experienced a faster increase in ASDR and ASR-DALYs for neonatal disorders.
    Although the burden of neonatal disorders shows a downward trend from 1990 to 2019, it is still not optimistic. It is necessary to implement a multi-pronged approach to reduce the increasing burden of neonatal disorders.

    新兴的营养精神病学领域提供了证据,证明可以改变饮食质量以降低患精神疾病的风险。你吃什么对青少年的心理健康有很大的影响,以及早餐的质量和频率,以及不同的食物组,会影响青少年的心理健康。在这项研究中,采用回归模型分析了四个指标(自评健康状况,身体满意度,生活满意度,和八个症状)的心理健康问题以及人口因素(性别,年龄,身体质量指数,富裕阶层,身体活动),显示回归连接的林图。这项研究,一项针对3480名11至15岁青少年的描述性横断面调查,从2018年希腊学龄儿童健康行为(HBSC)国际研究中选择的数据进行二次分析。数据显示,心理健康的四个指标(自我评估健康,身体满意度,生活满意度,和八个症状)与早餐质量显着相关,总膳食模式。学生报告整体食品质量差,例如,在不健康时,自我评估更具预测性(2.28695%CI1.851-2.824),当八种精神状态症状最差时,发现与吃“坏”早餐的最大联系(-0.86995%CI:-1.300,-0.439);体育锻炼可能会增强饮食质量对心理健康的正关系,肥胖削弱了这种积极的关系;年龄模式因性别而异,女孩和老年人表现出更高的饮食质量和心理健康风险。结论:研究结果表明,一般心理健康的四个指标中的每个指标都与青少年早餐和整体饮食质量相关。体力活动和体重被证明是调节因素,肥胖对心理风险的影响最大。性别,年龄,家庭经济不平等是心理症状上升的潜在原因。敦促研究人员更多地关注营养精神病学研究,并研究未来的心理感知差异。什么是已知的:•青少年饮食模式或质量与心理健康之间存在潜在的相关性。•年龄等因素,性别,社会经济地位,体重和身体活动都会对饮食和心理健康产生影响。新增内容:•目前还没有研究同时预测早餐质量和总体饮食质量的能力,以广泛定义的心理健康投诉[积极(生活满意度),中性(身体满意度,自我评估的健康)和负面(八个症状:情绪低落,烦躁,紧张,睡眠困难,头晕,头痛,胃痛和背痛)]。•人口统计学亚组之间的总体饮食质量趋势差异仍不清楚。
    The emerging field of nutritional psychiatry offers proof that diet quality can be changed to reduce one\'s risk of developing mental illness. What you eat has a big impact on teenage mental health, and the quality and frequency of breakfast, as well as the different food groups, can affect adolescent mental health. In this study, regression models were employed to analyze four indicators (self-rated health, body satisfaction, life satisfaction, and eight symptoms) of mental health problems as well as demographic factors (gender, age, body mass index, affluence class, physical activity), with forest plots displaying the regression connections. This study, a descriptive cross-sectional survey of 3480 adolescents aged 11 to 15 years, chosen data from the 2018 Greek Health Behaviour in School-aged Children (HBSC) International Study for secondary analysis. The data revealed that high levels of four indicators of mental health (self-rated health, body satisfaction, life satisfaction, and eight symptoms) were significantly related to breakfast quality, total dietary patterns. Students reporting poor total food quality, for example, were more predictive of self-assessment when unhealthy (2.286 95% CI 1.851-2.824), and the largest connections with eating a \"bad\" breakfast were discovered when the eight symptoms of mental status were the worst (- 0.869 95% CI: - 1.300, - 0.439); physical activity may enhance the positive relationship of diet quality on mental health, while obesity weakens this positive relationship; and age patterns varied by gender, with girls and older individuals showing a higher risk of diet quality and mental health.   Conclusions: The findings revealed that each of the four indices of general mental health was correlated with teenage breakfast and overall diet quality. Physical activity and weight were shown to be moderating factors, and obesity had the biggest impact on psychological risk. Gender, age, and family economic inequality were potential explanations for the rise in psychological symptoms. Researchers are urged to focus more on nutritional psychiatry research and look into psychological perception disparities in the future. What is Known: • There is a potential correlation between adolescent dietary patterns or quality and mental health. • Factors such as age, gender, socio-economic status, body weight and physical activity all have an impact on diet and mental health outcomes. What is New: • There have been no studies of the ability to simultaneously predict breakfast quality and overall diet quality for broadly defined mental health complaints [positive (life satisfaction), neutral (body satisfaction, self-rated health) and negative (eight symptoms: depressed mood, irritability, nervousness, difficulty sleeping, dizziness, headache, stomachache and backache)]. • Differences in overall diet quality trends between demographic subgroups remain unclear.

    扁桃体门。Dorchin&Fazan被描述为新发现的gall虫物种(双翅目:Cecidoymiidae)在Zelkovaabelicea(Ulmaceae)的花朵中形成gall虫,地中海克里特岛(希腊)特有的树种。幼虫在雄花的修饰细丝内发育,与许多在花朵或简单的花朵中自由发育的Contarinia物种相反。该物种每年有一代,有时在单个树上发现大量的gall,从而影响水果的数量和重量。这是Zelkova的gall虫的第一份报告,也是Ulmaceae的Contarinia的第一份记录。基于其寄主植物关联和mtCOI基因的条形码部分,该物种在Contarinia内没有明显的亲戚。
    Contarinia ampelitsiae n. sp. Dorchin & Fazan is described as a newly discovered gall-midge species (Diptera: Cecidoymiidae) forming galls in flowers of Zelkova abelicea (Ulmaceae), a tree species endemic to the Mediterranean island of Crete (Greece). Larvae develop within modified filaments of male flowers, contrary to many Contarinia species that develop freely in flowers or in simple flower galls. The species has one generation per year, and its galls are sometimes found in great numbers on individual trees, thus affecting both fruit quantity and weight. This is the first report of a gall midge from Zelkova and the first record of Contarinia from Ulmaceae. Based on its host-plant association and on the barcoding section of the mtCOI gene, this species has no obvious relatives within Contarinia.

    抑郁症患病率在青春期/成年早期显着增加。青年时期的抑郁症可能会产生自杀意念,而自杀是这个年龄段死亡的主要原因。此外,青少年/年轻人经常报告可能部分是由于抑郁症状引起的睡眠问题.抑郁症之间的关联研究,该年龄组的睡眠投诉和自杀倾向有限。我们的目的是研究抑郁症状之间的关联,睡眠投诉和自杀意念大(n=2771),青少年代表性样本(年龄:15-17岁,n=512)和年轻人(年龄:18-24岁,n=2259)来自希腊的普通人群。进行了电话结构化问卷。使用改良的患者健康-7问卷评分评估抑郁症状,虽然使用患者健康-9问卷的第九和第三个问题评估了自杀意念和睡眠投诉的存在,分别。中介逻辑回归分析显示,从抑郁症状到睡眠主诉(比值比[OR]1.22,95%置信区间[CI]1.19-1.24;OR1.21,95%CI1.18-1.24)和自杀意念(OR1.18,95%CI1.14-1.22;OR1.18,95%CI1.14-1.22)。以及睡眠投诉和自杀意念(OR1.82,95%CI1.32-2.50;OR1.91,95%CI1.33-2.76),分别,但不是在青少年中。此外,在年轻人中,我们发现抑郁症状对睡眠主诉介导的自杀意念有显著的间接影响(18.8%).这些发现支持以下假设:在患有抑郁症的年轻人中治疗睡眠障碍可以独立地进一步降低自杀风险。
    Depression prevalence increases significantly during adolescence/early adulthood. Depression in youth may present suicidal ideation, while suicide represents the leading cause of death in this age group. Moreover, adolescents/young adults frequently report sleep complaints that may partially be due to depressive symptoms. Studies on the associations between depression, sleep complaints and suicidality in this age group are limited. We aimed to examine associations between depressive symptoms, sleep complaints and suicidal ideation in a large (n = 2771), representative sample of adolescents (age: 15-17 years, n = 512) and young adults (age: 18-24 years, n = 2259) from the general population in Greece. A telephone structured questionnaire was administered. Depressive symptoms were assessed using the modified Patient Health-7 questionnaire score, while presence of suicidal ideation and sleep complaints were assessed using the ninth and third question of Patient Health-9 questionnaire, respectively. Mediation logistic regression analysis revealed significant direct paths from depressive symptoms to sleep complaints (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.19-1.24; OR 1.21, 95% CI 1.18-1.24) and suicidal ideation (OR 1.18, 95% CI 1.14-1.22; OR 1.18, 95% CI 1.14-1.22), as well as sleep complaints and suicidal ideation (OR 1.82, 95% CI 1.32-2.50; OR 1.91, 95% CI 1.33-2.76) in the total group and in young adults, respectively, but not among adolescents. Moreover, we detected a significant indirect effect of depressive symptoms on suicidal ideation mediated by sleep complaints (18.8%) in young adults. These findings support the hypothesis that treatment of sleep disturbances among youth with depression may independently further reduce suicidal risk.

    环境服务贸易的发展对于实现气候目标和绿色经济转型至关重要。基于2001-2019年的环境服务贸易数据,运用社会网络分析(SNA)方法刻画全球环境服务贸易网络的结构特征,基于二次分配过程(QAP)模型对网络演化的影响机制进行了实证检验。结果表明,全球环境服务贸易目前处于反弹稳定期。环境服务贸易的市场日趋多元化,贸易的可达性和便利性不断提高,网络中存在明显的核心边缘结构。比利时,意大利,荷兰是全球环境服务贸易网络的中心;希腊,作为最突出的贸易追赶国,已逐渐成为重要的“桥梁”和“枢纽”。“气候变化,地理距离,和人口规模是影响全球环境服务贸易网络的关键因素;环境规制,经济距离,和绿色技术距离对全球环境服务贸易的发展没有显著影响,语言差异不再是这种贸易增长的障碍。结果表明,各国应以更加开放的态度,在环境服务领域深入开展跨国贸易合作。政府要对环境服务进出口给予足够的政策支持,保障环境服务贸易的发展。
    The development of the environmental services trade is crucial to achieving climate goals and a green economic transition. Based on environmental services trade data from 2001 to 2019, this work uses the social network analysis (SNA) method to depict the structural features of global environmental services trade networks, empirically testing the influencing mechanism of network evolution based on the quadratic assignment procedure (QAP) model. The results indicate that the global environmental services trade is now in a rebound stable period. The market of the environmental services trade is becoming increasingly diversified, the accessibility and convenience of trade are constantly being enhanced, and there is an obvious core-edge structure in the network. Belgium, Italy, and the Netherlands are at the center of the global environmental services trade network; Greece, as the most prominent trade catch-up country, has gradually become an important \"bridge\" and \"hub.\" Climate change, geographical distance, and population size are the key factors affecting the global trade network of environmental services; environmental regulation, economic distance, and green technology distance have no significant impact on the development of the global environmental services trade, and language difference is no longer an obstacle to the growth of this trade. The results indicate that countries should develop in-depth transnational trade cooperation in the field of environmental services and do so with a more open attitude. The government should give sufficient policy support to the import and export of environmental services, guaranteeing the development of the environmental services trade.

    成年个体在吸引和保持伴侣方面经常遇到困难,这是单身的重要驱动力。在目前的研究中,我们调查了交配性能(即,在14个不同的国家,人们在吸引和留住亲密伴侣)和单身身份方面做得有多好,即奥地利,巴西,中国,希腊,匈牙利,意大利,Japan,秘鲁,波兰,俄罗斯,西班牙,土耳其,英国,和乌克兰(N=7,181)。我们发现不良的交配性能很高,大约四分之一的参与者在这个维度上得分较低,超过57%的人在开始和/或保持一段关系时面临困难。男性和女性的交配表现得分没有差异,但是年龄的影响很小但很大,年龄较大的参与者表现出更高的交配性能。此外,近13%的参与者表示他们不由自主地单身,约占样本中单身人士的三分之一。此外,超过15%的参与者表示他们自愿单身,10%是单身关系。我们还发现,不良的交配表现与自愿的可能性增加有关,非自愿,和单身之间的关系。所有类型的单身在年轻参与者中的发生率都较高。虽然有一些跨文化的差异,样本间的结果基本一致.
    Adult individuals frequently face difficulties in attracting and keeping mates, which is an important driver of singlehood. In the current research, we investigated the mating performance (i.e., how well people do in attracting and retaining intimate partners) and singlehood status in 14 different countries, namely Austria, Brazil, China, Greece, Hungary, Italy, Japan, Peru, Poland, Russia, Spain, Turkey, the UK, and Ukraine (N = 7,181). We found that poor mating performance was in high occurrence, with about one in four participants scoring low in this dimension, and more than 57% facing difficulties in starting and/or keeping a relationship. Men and women did not differ in their mating performance scores, but there was a small yet significant effect of age, with older participants indicating higher mating performance. Moreover, nearly 13% of the participants indicated that they were involuntarily single, which accounted for about one-third of the singles in the sample. In addition, more than 15% of the participants indicated that they were voluntarily single, and 10% were between-relationships single. We also found that poor mating performance was associated with an increased likelihood of voluntary, involuntary, and between-relationships singlehood. All types of singlehood were in higher occurrence in younger participants. Although there was some cross-cultural variation, the results were generally consistent across samples.

    体育素养(PL)的概念已被提倡为提高运动和体育活动(PA)的质量和数量的关键决定因素。儿童的PL很少在各个国家进行比较,尽管它在许多国家表现出低水平。本研究旨在探讨和比较中国和希腊儿童的PL。
    共有327名中国人(47.1%的男孩)和295名希腊儿童(48.1%的男孩)参加了这项研究,年龄在8至12岁之间。中国和希腊版的加拿大体育素养评估客观地评估了儿童的PL,第二版,它由四个领域组成:日常行为,身体能力,动机和信心,和知识。和理解。在这两个国家对总PL和领域得分进行了单变量协方差分析(ANCOVA)和多变量协方差分析(MANCOVA)。分别。
    MANOVA揭示了两个国家之间总PL和分布得分的显着差异(Pillais\'trace=0.260,F=53.855,p<0.001,η2=0.260),希腊孩子的得分比中国好。然而,大多数儿童未能表现出足够的PL水平,因为他们大多处于“进步”阶段。卡方表示,中国和希腊参与者在CAPL-2解释类别中的分布在总PL中具有统计学差异(χ2[3]=18.726,p<0.001,Cramer\sV=0.174),更多的希腊儿童被归类为“成就”和“优秀”。
    中国和希腊儿童之间的差异可能归因于PA背景下的文化差异,例如PE策略和设置。这两个国家的PL水平相对较低,这与全球儿童PA下降的趋势相呼应。随着他们久坐不动的生活方式的时间越来越多。这些发现强调了在发展儿童的PL方面需要考虑儿童的文化因素和教学策略。未来的研究需要探索文化背景对儿童PL发展的影响以及适当的策略来迁移他们的影响。
    The concept of physical literacy (PL) has been advocated as a crucial determinant for increasing the quality and quantity of movement and physical activity (PA). Children\'s PL has been rarely compared across countries, although it has shown low levels in many countries. This study aimed to explore and compare children\'s PL from China and Greece.
    A total of 327 Chinese (47.1% boys) and 295 Greek children (48.1% boys) aged 8 to 12 years participated in this study. Children\'s PL was objectively assessed by the Chinese and Greek version of the Canadian Assessment of Physical Literacy, 2nd edition, which consists of four domains: Daily Behavior, Physical Competence, Motivation and Confidence, and Knowledge. and Understanding. Univariate analysis of covariance (ANCOVA) and multivariate analysis of covariance (MANCOVA) on total PL and domain scores were conducted in both countries, respectively.
    MANOVA revealed significant differences in total PL and distribution scores between two countries (Pillais\' trace = 0.260, F = 53.855, p < 0.001, η2 = 0.260), with Greek children scoring better than Chinese. Nevertheless, most children failed to present an adequate PL level as they were mostly in the \"progressing\" stage. The chi-square denoted that the distribution of Chinese and Greek participants across the CAPL-2 interpretive categories was statistically different for total PL (χ2 [3] = 18.726, p < 0.001, Cramer\'s V = 0.174), with more Greek children being classified as \"achieving\" and \"excelling\".
    The variance between Chinese and Greek children may be attributed to cultural differences in the context of PA, such as PE policies and settings. The relatively low level of PL shown in both countries echoes the global trend of the declining PA among children, with an increasing amount of their time spent in a sedentary lifestyle. These findings highlight the need to consider children\'s cultural factors and pedagogical strategies in terms of developing their PL. Future research is required to explore the impact of cultural background on PL development among children and appropriate strategies to migrate their influence.

    丹参在古埃及被认为是一种有益的治疗草药,罗马和希腊,并在世界许多国家的药典中被列为官方药物。目前,丹参广泛用于调味和保存食物。这里,两种未描述的降氮烷型二萜,sadigitaloidesA和B,两种未描述的germacrane型倍半萜,SadigitaloidesC和D,五种未描述的愈创木酯型倍半萜内酯,SadigitaloidesE-I,两种未描述的Noreudesmane型倍半萜,sadigitaloidesJ和K,一种已知的二萜,三种已知的倍半萜,从丹参全植物的95%乙醇提取物中分离出其他三种类型的已知化合物。使用1D和2DNMR光谱技术表征了它们的结构和绝对构型,电子圆二色性(ECD)计算,HRESIMS实验,和单晶X射线衍射分析。评估了一些化合物对脂多糖(LPS)诱导的大鼠巨噬细胞NR8383细胞中TNF-α产生的抗炎活性。SadigitaloideA在100.0μM的浓度下显示出明显的抗炎活性。浓度为60μM时,在由6-OHDA损伤的秀丽隐杆线虫模型中,与阳性对照正丁二苯酞相比,sadigitaloideB对多巴胺能神经元的保护作用更好。某些化合物的植物毒性活性归因于对RaphanussativusL幼苗的根和下胚轴生长的相当大的抑制作用,尤其是顺式,反式脱落酸,在50至400ppm的浓度范围内,其抑制率远高于草甘膦。这些结果表明,松香烷型二萜具有优异的抗炎和神经保护活性,并进一步表明低分子量化合物具有出色的植物毒性活性。
    Salvia has been regarded as a beneficial healing herb in ancient Egypt, Rome and Greece, and is listed as an official medicine in the pharmacopoeias of many countries worldwide. Currently, Salvia is widely used to flavor and preserve food. Here, two undescribed norabietane-type diterpenoids, sadigitaloides A and B, two undescribed germacrane-type sesquiterpenoids, sadigitaloides C and D, five undescribed guaiane-type sesquiterpenoid lactones, sadigitaloides E-I, two undescribed noreudesmane-type sesquiterpenoids, sadigitaloides J and K, one known diterpenoid, three known sesquiterpenoids, and three other types of known compounds were isolated from the 95% ethanol extract of the whole plants of Salvia digitaloides. Their structures and absolute configurations were characterized using 1D and 2D NMR spectroscopic techniques, electronic circular dichroism (ECD) calculations, HRESIMS experiments, and single-crystal X-ray diffraction analysis. Some compounds were evaluated for their anti-inflammatory activities against lipopolysaccharide (LPS)-induced TNF-α production in rat macrophage NR8383 cells. Sadigitaloide A showed noticeable anti-inflammatory activity at a concentration of 100.0 μM. At a concentration of 60 μM, sadigitaloide B exhibited better protection of dopaminergic neurons than the positive control n-butylidenephthalide in the Caenorhabditis elegans model injured by 6-OHDA. The phytotoxic activities of some compounds were attributed to considerable inhibitory effects on the growth of the roots and hypocotyls of Raphanus sativus L seedlings, especially cis, trans-abscisic acid, whose inhibition rates were much higher than those of glyphosate at concentrations ranging from 50 to 400 ppm. These results indicated that abietane-type diterpenoids possessed excellent anti-inflammatory and neuroprotective activities and further suggested that the low-molecular-weight compounds exhibited outstanding phytotoxic activities.

    Using the philological method, the comparison was conducted between the internal canals of human body, meaning the four pairs of \"phleps\" in the ancient Greek medicine, and the eleven \"mai\" (meridians, vessels, channels) of Mawangdui silk manuscripts. It is believed that they refer to the initial understanding on the connecting passages of the human body in Western medicine and Chinese medicine respectively. Although they have their own unique characteristics, there are many similarities in running courses, related indications, diagnosis and treatment, as well as theoretic foundation. Both of them represent the duality of tangible blood vessels and intangible pathways, reflecting the common cognitive mode of human body and diseases in early human medicine, with the similar characteristics, e.g.analogy, examining the exterior to deduce the conditions in the interior, holistic connection and natural balance. The four pairs of \"phleps\" of ancient Greek medicine, with the preliminary features of meridians, were substituted by the blood circulation theory afterwards; whereas, the eleven \"mai\" of Mawangdui silk manuscripts were developed into a twelve-meridian system. These different evolution paths and outcomes may be associated with the distinct medical philosophies and cultural backgrounds between ancient Greek medicine and Chinese medicine. This summary provides a new approach and new perspectives for the study on the regularity of the early human medical origin, especially the origin of meridians.
    本文通过文献学方法将古希腊医学中人体内管道——4对“phleps”与马王堆帛书十一脉进行比较, 认为二者分别是西医学和中医学在起源阶段对人体内联络通道的认识, 虽各有特点, 但在循行、相关病候、诊治和理论等方面有诸多相似性;二者都具有实体血管与抽象通道的二重性, 反映了人类早期医学对人体和疾病共同的认知模式, 都有取象比类、司外揣内、整体联系和自然平衡等特点;古希腊医学中具有经络萌芽特点的4对“phleps”后来被血液循环理论代替, 而马王堆帛书十一脉发展成为十二脉体系。二者不同变迁道路和结局可能与其不同的医学哲学和文化背景有关。本研究为人类早期医学起源的规律性认识尤其是经络起源研究提供了新思路和新视角。.
