Pyrethroid esters are widely used as insecticides worldwide. In this study, we aimed to evaluate the harmful effect of deltamethrin on the male reproductive system through the assessment of reproductive hormones, inflammatorymarkers, and testicular function. To achieve our aim, eighty male 7-9-week-old, Wistar rats were taken, weighed, and divided into four experimental groups. The first group was kept as a control group, and the other three groups were given deltamethrin orally at different concentrations (0.87, 8.7, and 17.4 mg/kg body weight) for nine weeks. The resultsindicated that deltamethrin administration associated with a significant decrease in reproductive hormones, especially FSH, LH, and significant elevation in the interleukin 2 (IL2), interleukin 6 (IL6), histamine, and cortisol levels. Also, thesignificance of inhibition of sperm motility and viability, decreased testis weights, sperm count, and fructose in semen were noted. These findings clarify the harmful effect of deltamethrin on the male reproductive system by producing a significant alteration in reproductive hormones, inflammatory markers as well as testicular function.

目的:采用食管癌患者外周血来源的外泌体干预食管癌ECA109细胞,检测肿瘤细胞的增殖、凋亡、迁移及Wnt/β-catenin和PI3K-AKT信号通路蛋白的表达变化,探讨食管癌外泌体在肿瘤细胞发展进程中的作用。方法:超高速离心法提取食管癌患者外周血血清中的外泌体,与食管癌ECA109细胞共培养,检测细胞增殖、凋亡、迁移等生物学行为的变化;Western-blot检测AKT、β-catenin蛋白的表达。结果:透射电镜、粒径测定、标志蛋白结果证实提取的食管癌患者血清外泌体符合其鉴定标准;与空白细胞组相比,食管癌外泌体干预后食管癌ECA109细胞增殖、迁移能力显著提高,G 2+S期细胞比例升高,细胞凋亡比例降低,统计学差异显著;食管癌外泌体组AKT蛋白磷酸化表达水平较空白细胞组明显升高,β-catenin蛋白表达显著降低。结论:食管癌来源的外泌体具有促进肿瘤细胞增殖与迁移、抑制细胞凋亡的作用,其机制可能与PI3K-AKT信号通路关键激酶AKT的激活有关,提示在肿瘤发展进程中肿瘤来源外泌体的作用不容忽视。

AIM： To assess whether CCL2 or interactions between this chemokine and its receptor （CCR2） are associated with outcomes of chronic hepatitis C and with responses to antiviral therapy. METHODS： Two hundred and eighty-four patients with chronic hepatitis C and 193 non-infected matched controls were included in this study. Patients were categorized according to their Scheuer score of hepatic fibrosis as F0-F2 （/7 = 202） or F3-F4 （/7 = 82） and according to their response to anti-Hepatitis C virus （HCV） therapy as sustained response （SR, n = 201） or non-sustained response （NSR, n = 98）. Genotyping of the -2518 （A/G） CCL2 was performed using PCR-RFLP, genotyping of the 190 （A/G） CCR2 using a PCR-ARMS system, and genotyping of the rs3138042 （G/A） CCR2 using Taqman probes. RESULTS： Univariate analyses identified 4 parameters （infection duration time, viral genotype, gender and AST levels） that tended to influence fibrosis and 7 parameters （CCL2G, CCL2ACCR2A, viremia levels, fibrosis stage, viral genotype, infection duration time and AST levels） that significantly influenced or tended to influence response to treatment. Multivariate analysis identified gender and AST levels as parameters that independently influenced fibrosis stage and viral genotype and infection duration time were the two parameters that independently influenced response to treatment. CONCLUSION： Our results indicate that the mutations studied in the gene pair CCL2/CCR2 do not play a major role in the outcome and response to treatment for HCV infection in the Spanish population.

坚持总体国家安全观,是维护国家安全的新要求。刑法与总体国家安全具有密切关系。在总体国家安全中,刑法安全观须臾不可缺失。维护总体国家安全是刑法的核心任务,高度重视总体国家安全,这是时代的呼唤。总体国家安全中的“总体”要求和刑法惩治犯罪行为的广泛性具有对应关系。刑法内容的细致性、手段的多样性和执行的强制性,为总体国家安全中的“安全”提供坚实有力的法治保障。我国总体国家安全的基本法律体系,以宪法为总纲,以国家安全法为主线,以刑法为保障手段。如何维护总体国家安全,刑法总则和分则有细致规定,在体例、行为性质判定、罪名确定、刑罚以及发展变化上呈现出相应特点。但也存在问题,主要表现在立法理念、协调机制、执法效果、秩序构建、环境营造等方面,应当通过确立宪法原则、总体国家安全刑法观原则、刑事政策同步跟进原则等完善指导体系,通过健全刑法和国家安全法衔接机制,充实总体国家安全刑事政策等完善机制体系,通过保障要素安全、一体化维护等完善措施体系。

为解决桥梁健康监测系统中传感器优化布置问题,提出一种基于自适应鲸鱼优化算法的传感器布置方法。通过Fisher信息阵二范数变化率和模态有效参与质量提取模态,有效避免模态冗余。引入Kent映射生成初始测点,以模态置信准则为适应度函数。针对鲸鱼算法中参数既控制算法的全局和局部搜索又控制算法的搜索步长,且其开发能力不足等问题,将鲸鱼算法中的参数A分解为决策因子A1和衰减因子A2。通过决策因子A1控制鲸鱼算法的全局和局部搜索,增强算法跳出局部最优的能力;通过衰减因子A2动态调整算法的搜索步长,提升鲸鱼算法搜索效率和精度。通过哈齐大桥进行实例验证,结果表明,改进后鲸鱼算法的模态置信矩阵精度相比粒子群算法提升82.29%。
