TRIM59 通过结合 BCLAF1 调控人皮肤黑色素瘤 SK-MEL-2 细胞的恶 性生物学行为

目的：探究三结构域蛋白59（TRIM59）调控人皮肤黑色素瘤细胞SK-MEL-2增殖、细胞周期、凋亡及迁移侵袭的作用机制，及其与Bcl2相关转录因子1（BCLAF1)之间的关系。方法：qPCR和WB法检测人表皮黑色素细胞HEMn-LP、人皮肤黑色素瘤细胞SK-MEL-2、UACC903、A375及36例邢台市人民医院2019年2月至2021年7月收集的皮肤黑色素瘤组织中TRIM59的mRNA和蛋白表达，使用脂质体将si-con、si-TRIM59转染至SK-MEL-2细胞中，WB法检测干扰TRIM59表达对细胞中周期蛋白D1（CCND1）、细胞周期素依赖性激酶2（CDK2）、肿瘤抑制蛋白基因（TP53）和 BCLAF1 蛋白表达的影响，CCK-8法、流式细胞术、划痕愈合实验、Transwell实验检测对细胞的活性、凋亡、迁移和侵袭的影响，免疫共沉淀（Co-IP）实验检测对细胞中TRIM59蛋白与BCLAF1结合能力的影响。结果：与HEMn-LP细胞相比，SK-MEL-2、UACC903、A375细胞中TRIM59 mRNA和TRIM59、BCLAF1蛋白均呈高表达（均P<0.05），SK-MEL-2细胞中TRIM59表达水平最高。相较于si-con组和Normal组，沉默TRIM59后，SK-MEL-2细胞的活性显著降低，细胞周期阻滞于G2期，CCND1、CDK2的蛋白表达显著降低，TP53蛋白和细胞凋亡率均显著升高，划痕抑制率明显升高，迁移侵袭细胞数明显降低（均P<0.05）。免疫共沉淀实验结果显示，TRIM59与BCLAF1之间存在蛋白结合关系。TRIM59与 BCLAF1 在肿瘤组织中的表达呈显著的正相关（r=0.878，P<0.001）。结论：干扰TRIM59表达能够抑制人皮肤黑色素瘤SK-MEL-2细胞的增殖、迁移和侵袭而促进凋亡，抑制SK-MEL-2细胞的恶性生物学行为，其机制可能与TRIM59结合BCLAF1有关。     

A Lifestyle Intervention Program to Improve Knowledge and Health Behaviors in Women

ObjectiveTo improve health knowledge, facilitate healthy behaviors, and provide social support for a high-risk population of women by implementing a culturally tailored, gender-specific lifestyle intervention program.DesignEvidence-based practice project.Setting/Local ProblemA Chicago neighborhood in Cook County, Illinois, where there are increased rates of diabetes, heart disease, cancer, stroke, hypertension, obesity, preterm birth, and violent crime.ParticipantsFemale residents of the community, ages 19 to 45 years; 12 participants registered for the program, and 11 participants completed the entire 2-month program.Interventions/MeasurementsThe BE WISE Lifestyle Intervention, a culturally tailored, gender-specific behavior change curriculum, was used for this project. An interprofessional team was used to enhance participant experience, and neighborhood collaborations were established to create sustainability of efforts. Pre- and postintervention measures of diet, physical activity, social support, and knowledge acquisition were used to evaluate outcomes.ResultsImprovement was noted for knowledge in most of the content areas, as well as for dietary and physical activity behaviors. All participants rated the program highly and responded positively to the social support experienced in the group.ConclusionCulturally tailored lifestyle interventions can be effective in improving knowledge and encouraging behavior change, especially when delivered in group settings to enhance social support. Community-level collaborations enhance interventions by providing local support and resources for participants. Because behavior change takes time, follow-up at the 6-month and 1-year intervals is recommended to determine longer-term outcomes.

Food-grade titanium dioxide decreases hematocrit and hemoglobin and increases compulsive-like behavior in male mice

Food-grade titanium dioxide (E171) is widely used as a food additive, and it is known that after oral consumption, E171 is translocated into the bloodstream reaching the highest titanium level at 6 h. E171 is accumulated in some organs triggering toxicity, but the effects on the blood parameters after oral consumption have been less studied. Recently, evidence shows that oral exposure to E171 induces behavioral signs of anxiety and depression. The relation between blood alterations and psychiatric disorders has been previously demonstrated. However, the oral exposure to E171 effects on alterations in blood parameters and effects linked to alterations in animal behavior has not been explored. In this short communication, we aimed to investigate the effects of E171 on specific blood parameters (hematocrit, hemoglobin, number of erythrocytes, and leukocytes) and anxiety and compulsive-like behavior in males and females orally exposed to ~5 mg/kg for 4 weeks. The results showed that E171 decreased hematocrit and hemoglobin in male but not in female mice while leukocyte and erythrocyte count remained unaltered. Oral consumption of E171 decreased the levels of anxiety-like behavior in females but not in male mice, while compulsive-like behavior was increased in both male and female mice.     

Handcrafted firearm suicide: About the unusual use of a mole gun

The body of a man was found in a workshop at the back of his home, a metal pipe embedded in his chest. In the immediate vicinity of the body, among various tools, was a machine containing a holster hit of lead shot evoking a mole-trap-type “taupe gun” (mole gun).The findings at the scene and the presence of a metal tube, sinkers, and a flock in the chest are in favour of the use of a homemade firearm. The autopsy and CT scan revealed atypical ballistic thoracic trauma responsible for a dilaceration of both the heart and thoracic aorta that caused the death. The autopsy also found a contused wound at the back of the skull without intracranial lesion, which may be due to the fall of the victim after the thoracic trauma. There is no other traumatic lesion and in particular no lesion of seizure, constraint, or defense. Toxicological analyses revealed the presence of alcoholic impregnation at the time of death. These findings, confronted with the expertise of a balistician, made it possible to understand how the victim used a mole gun to cause these lesions. A metal tube was used as a cannon to aim more surely at the heart but also as a means of triggering the propulsion mechanism of the trap without having to stretch out the arm. The tube, thinner than the barrel, had disengaged from its tip to be embedded with the lead shot in the chest of the victim.     

综合提醒系统对脑卒中患者出院6个月知信行和临床结局的效果

目的 探讨健康信念综合提醒系统对脑卒中患者出院后6个月健康知识、信念、行为、卫生服务利用情况及临床结局的效果。方法 2015年2月至2016年3月,方便抽样广州市3家综合医院高血压并发缺血性脑卒中出院患者174例,分为对照组(n = 87)和干预组(n = 87)。对照组予常规健康教育;干预组在此基础上采用“基于健康信念模式的综合提醒系统”进行健康教育和延续护理。出院6个月后,采用脑卒中健康知识问卷(SKQ)、脑卒中患者健康信念简表(SF-HBMS-SP)和脑卒中健康行为量表(HBS-SP)进行调查,并记录临床结局(急诊就诊、再住院、复发和死亡)。结果 对照组75例、干预组76例完成调查。干预组SKQ (U = 903.000)、SF-HBMS-SP (t = -9.099)和HBS-SP (t = -7.786)总分均显著高于对照组(P < 0.001)。干预组门诊复诊率(97.37%)显著高于对照组(76.00%) ( P <0.001);两组急诊就诊数和再住院数无显著性差异(P > 0.05),死亡和复发率无显著性差异( P > 0.05)。 结论 健康信念综合提醒系统能提高脑卒中患者出院后健康知识、信念、行为和门诊复诊率,但尚未对临床结局产生明显效果。     

A benchmark dose study of prenatal exposure to di(2-ethylhexyl) phthalate and behavioral problems in children

IntroductionPrenatal exposure to di(2-ethylhexyl) phthalate (DEHP) has been reported to be associated with adverse effects on neurodevelopment that yield behavior syndromes in young children with an estimated median exposure lower than the currently recommended tolerable daily intake (TDI) and reference dose (RfD).ObjectivesOur aim was to derive the benchmark dose for prenatal exposure to DEHP for the neurodevelopmental health in children.MethodsA total of 122 mother-child pairs from the Taiwan Maternal and Infant Cohort Study were analyzed for the dose-response relationship between maternal exposure to DEHP and children's behavioral syndromes evaluated at 8 years (n = 122, 2009), 11 years (n = 96, 2012), and 14 years (n = 78, 2015) of age. We employed a multivariate regression model to assess the statistical associations between the estimated maternal average daily intake of DEHP and child's individual CBCL scores for boys and girls at each separate age, followed by a mixed model for all the children across three ages accounting for individual variations. We then employed structural equation models by combining the children's specific behavioral problem scores at different ages and obtained a simulated overall latent score in relation to maternal exposure. Based on the established dose-response relationship, we derived the benchmark dose (BMD) and the lower limit (BMDL).ResultsAssociations of maternal DEHP exposure (median 4.54$\mu g/kg\_bw/day$) with the Child Behavior Checklist (CBCL) scores were all significant, except for somatic complaints, adjusting for child's age, gender, IQ, and family income. The BMDL, given a benchmark response of 0.10 (0.05) and a background response of 0.05, was 6.01 (2.16) $\mu g/kg\_bw/day$for an integrated CBCL score.ConclusionsThe current TDI (RfD) of 50 (20) $\mu g/kg\_bw/day$ for DEHP might not protect pregnant women for their children from behavioral problems. There remains the lack of comparable toxicological data. Further investigations are needed.
