    这项研究的工作假设的基本思想是,今天唯一通过生化机制与牙周病明显相关的全身性疾病是糖尿病,以及临床发现糖尿病会导致许多特定的牙周变化。该研究的主要目的是强调诊断为2型糖尿病的患者牙周病期间炎症的生化标志物。为了实现这一目标,我们使用了Boster生物技术公司的人ELISA试剂盒,有限公司(普莱森顿,CA,美国),用于检测IL-1β,IL-4、IL-8和TNF-α。数据分析显示这些细胞因子的血浆水平与牙周炎的进展有关。总之,我们可以说,免疫标志物的参与在牙周病的发病机制中是很明显的。
    The basic idea from which the working hypothesis for this study started is the fact that the only systemic disease today that is clearly linked to periodontal disease by biochemical mechanisms is diabetes mellitus, as well as the clinical finding that diabetes causes a number of specific periodontal changes. Highlighting the biochemical markers of inflammation during periodontal disease in patients diagnosed with type 2 diabetes is the main aim of the study. To achieve this objective, we used the human ELISA kit from Boster Biological Technology Co., Ltd. (Pleasanton, CA, USA), for the detection of IL-1β, IL-4, IL-8 and TNF-α. The data analysis shows that plasma levels of these cytokines are associated with the progression of periodontitis. In conclusion, we can state that the involvement of immunological markers is evident in the pathogenesis of periodontal disease.

    目的:免疫功能紊乱是非霍奇金淋巴瘤(NHL)发生发展的危险因素之一,炎症可能与它的病因有关。在开始化疗之前,关于细胞因子水平对淋巴瘤神经行为功能的影响的数据很少。因此,我们旨在通过评估细胞因子和脂肪因子水平及其与神经行为改变的相关性来探讨NHL的风险.
    方法:本病例对照研究纳入62名受试者(年龄性别匹配:31例和31名对照)。使用蒙特利尔认知评估问卷(MoCA)和患者健康问卷(PHQ-9)进行神经行为评估。使用EORTC核心生活质量问卷(EORTCQLQ-C30)评估生活质量。在患者入组后和第一周期化疗前进行问卷评估和样本收集。
    结果:NHL患者和健康对照组的平均年龄分别为51.9±11.8和50±10.9岁,分别。NHL患者的IL-6(0.77±0.11)和TNF-α(1.47±1.31)水平明显高于对照组(分别为0.55±0.4和0.66±0.89),p值<0.005。此外,NHL患者的脂联素(0.31±0.24)和网膜素(0.46±0.1)水平明显低于对照组(分别为0.42±0.13和0.53±0.11),p值<0.005。与健康对照相比,在NHL患者中观察到较低的MoCA和EORTCQLQC-30评分和较高的PHQ-9评分。
    结论:我们的结果表明脂联素,网膜素IL-6和TNF-α可用作NHL风险的预诊断标志物。在NHL患者中观察到的神经行为变化可能会改变生活质量。
    OBJECTIVE: Immune dysfunction is one of the risk factors which plays an important role in the development of non-Hodgkin lymphoma (NHL), and inflammation may be involved in its etiology. Minimal data is available on the effect of cytokine levels on neurobehavioral function in lymphoma before the initiation of chemotherapy. Therefore, we aimed to explore the risk of NHL by assessment of cytokine and adipokine levels and their correlation with neurobehavioral changes.
    METHODS: This case-control study enrolled 62 subjects (age-sex matched: 31 cases and 31 controls). Neurobehavioral assessment was done using Montreal Cognitive Assessment questionnaire (MoCA) and Patient Health Questionnaire (PHQ-9). EORTC Core Quality of Life questionnaire (EORTC QLQ-C30) was used to assess quality of life. Questionnaire assessment and sample collection were done after the patient enrolment and before first cycle of chemotherapy.
    RESULTS: Mean age of NHL patients and healthy controls was 51.9 ± 11.8 and 50 ± 10.9 years, respectively. NHL patients showed significantly higher levels of IL-6 (0.77 ± 0.11) and TNF- α (1.47 ± 1.31) than controls (0.55 ± 0.4 and 0.66 ± 0.89, respectively) with p-value<0.005. Also, NHL patients showed significantly lower levels of adiponectin (0.31 ± 0.24) and omentin (0.46 ± 0.1) than controls (0.42 ± 0.13 and 0.53 ± 0.11, respectively) with p-value<0.005. Lower MoCA and EORTC QLQ C-30 scores and higher PHQ-9 scores were observed in NHL patients in comparison to healthy control.
    CONCLUSIONS: Our results showed that adiponectin, omentin IL-6 and TNF-α may be used as pre-diagnostic markers of NHL risk. Neurobehavioral changes observed in NHL patients may alter the quality of life.

    Introduction Clinically, the early prediction of the severity of COVID-19 is often challenging, as a dramatic change in severity can occur without warning. The severity of COVID-19 disease is associated with an increased level of inflammatory mediators, including cytokines. This study aimed to evaluate the association of the levels of cytokines interleukin (IL)-2, IL-6, tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), and IL-10 with the severity of COVID-19 in Bangladesh. Materials and methods This cross-sectional study included a total of 60 confirmed cases of COVID-19, comprising 30 severe cases (Group A) and 30 non-severe cases (Group B), and 10 healthy individuals (Group C) attending Bangabandhu Sheikh Mujib Medical University (BSMMU) from March 2021 to February 2022. The cytokine assay was performed using the human Th1/Th2/Th17 cytokine kit BD cytometric bead array (CBA) on the BD Accuri C6 Plus flow cytometer. Statistical analysis was conducted using IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York). Results The mean ages of the patients in Groups A, B, and C were 60.73±5.97, 57.13±7.68, and 48.10±9.13 years, respectively, with a male predominance in all groups. The mean IL-2, IL-6, IL-10, and TNF-α levels had a positive correlation with the increased age group and male gender, although it was not statistically significant. The mean IL-6 and IFN-γ levels were significantly higher among severe cases (216.95±147.78 and 0.98±0.95 pg/mL, respectively) compared to non-severe cases (94.29±128.79 and 0.41±0.61 pg/mL, respectively) and healthy individuals (1.08±1.97 and 0.15±0.28 pg/mL, respectively). Furthermore, the anti-inflammatory cytokine IL-10 was also significantly higher among severe cases (17.92±21.87 pg/mL) compared to non-severe cases (5.38±6.73 pg/mL) and healthy individuals (1.62±1.65 pg/mL). Conclusion IL-6, IFN-γ, and IL-10 have a significant association with the severity of COVID-19 disease. Clinicians treating patients with COVID-19 can consider the level of these cytokines as biomarkers of severity.

    背景:这项回顾性研究调查了血清炎症标志物在鼻咽癌(NPC)患者中的预后价值,重点关注它们与总生存期(OS)和无肝转移生存期(LMFS)的关系。
    方法:该研究包括2010年至2020年期间接受治疗的314例NPC患者。临床特征,治疗方法,和血清炎症标志物进行评估。患者分为有肝转移和无肝转移两组。进行单因素和多因素Cox回归和Kaplan-Meier生存分析,以研究血清炎症标志物在有和没有肝转移的NPC患者中的预后价值。
    结果:在整个队列中,单因素Cox回归分析挑出肿瘤坏死因子-α(TNF-α)(HR=1.57,95%CI1.44-4.90,p=0.004)和中性粒细胞与淋巴细胞比率(NLR)(HR=2.13,95%CI1.33-3.99,p=0.009),这与OS较差显著相关。在肝转移患者中,TNF-α和NLR不能独立预测OS。然而,在无肝转移的患者中,高TNF-α水平与OS恶化独立相关(HR(95%CI)=2.75(1.67-8.68),p<0.001)。高NLR水平可以独立预测两组的不良OS(HR(95%CI)=1.94(1.77-6.38),p=0.010)且无肝转移(HR(95%CI)=1.58(1.19-7.54),p=0.009)。最终,TNF-α和NLR不能显著预测LMFS。
    结论:这项研究强调了TNF-α和NLR在鼻咽癌患者中的预后意义。尤其是肝转移患者.这些炎症标志物可以作为评估NPC患者预后的有价值的指标。有必要进行进一步的研究以验证其临床实用性并探索潜在的治疗意义。
    BACKGROUND: This retrospective study investigated the prognostic value of serum inflammatory markers in nasopharyngeal carcinoma (NPC) patients, focusing on their association with overall survival (OS) and liver metastasis-free survival (LMFS).
    METHODS: The study included 314 NPC patients treated between 2010 and 2020. Clinical characteristics, treatment methods, and serum inflammatory markers were assessed. Patients were categorized into two groups of with and without liver metastasis. Univariate and multivariate Cox regression and Kaplan-Meier survival analyses were performed to investigate the prognostic value of serum inflammatory markers in NPC patients with and without liver metastasis.
    RESULTS: In the whole cohort, univariate Cox regression analysis singled out tumor necrosis factor-α (TNF-α) (HR = 1.57, 95% CI 1.44-4.90, p = 0.004) and neutrophil-to-lymphocyte ratio (NLR) (HR = 2.13, 95% CI 1.33-3.99, p = 0.009), which were significantly associated with poorer OS. In patients with liver metastasis, TNF-α and NLR could not independently predict OS. However, high TNF-α levels were independently associated with worse OS in patients without liver metastasis (HR (95% CI) = 2.75 (1.67-8.68), p < 0.001). High NLR levels could independently predict poor OS in both groups with (HR (95% CI) = 1.94 (1.77-6.38), p = 0.010) and without liver metastasis (HR (95% CI) = 1.58 (1.19-7.54), p = 0.009). Ultimately, TNF-α and NLR could not significantly predict LMFS.
    CONCLUSIONS: This study highlights the prognostic significance of TNF-α and NLR in NPC patients, especially in those with liver metastasis. These inflammatory markers could serve as valuable indicators for assessing the prognosis of NPC patients. Further research is warranted to validate their clinical utility and explore potential therapeutic implications.

    已知肿瘤坏死因子α(TNF-α)与慢性炎症有关,其表达在晚期癌症中增加。慢性炎症是口腔粘膜下纤维化(OSMF)的特征,这是一种潜在的恶性疾病(PMD)。鳞状细胞癌(SCC)与相当大的死亡率和发病率相关,早期发现或监测将极大地有助于实现有效的治愈。因此,根据口腔和口咽中的OSMF阶段和SCC的组织学分级,评估了TNF-α在本研究中用作生物标志物。
    这项研究包括45名患者,分为3组-OSMF组,SCC组和对照组-每组包括15名参与者。收集每位患者的唾液样本,使用ELISA试剂盒估计唾液TNF-α水平。
    统计分析显示,OSMF之间的TNF-α水平没有显着差异,SCC和对照组;然而,根据OSMF的临床分期,3期患者的唾液TNF-α水平升高,p值为0.027。
    随着临床分期的增加,TNF-α浓度的增加表明TNF-α在OSMF参与口腔和口咽解剖结构的传播中起作用。OSMF中唾液TNF-α水平无显著差异,SCC和对照组。
    该研究显示TNF-α与OSMF的增加阶段呈正相关,但在相同的分类中不是可靠的生物标志物。
    UNASSIGNED: Tumor necrosis factor α (TNF-α) is known to be associated with chronic inflammation, and its expression has been shown to increase in advanced cancers. Chronic inflammation is a characteristic feature of oral submucous fibrosis (OSMF), which is a potentially malignant disorder (PMD). Squamous cell carcinoma (SCC) is associated with considerable mortality and morbidity and an early detection or monitoring would greatly help in achieving an effective cure. TNF-α was thus evaluated for use as a biomarker in the present study according to the stage of OSMF and histological grade of SCC in the oral cavity and oropharynx.
    UNASSIGNED: This study included 45 patients divided into 3 groups-OSMF group, SCC group and control group-each comprising 15 participants. Saliva samples were collected from each patient, and salivary TNF-α levels were estimated using an ELISA kit.
    UNASSIGNED: Statistical analysis revealed no significant differences in TNF-α levels among the OSMF, SCC and control groups; however, there was an increase in the salivary TNF-α level in patients with stage 3 disease according to the clinical stage of OSMF, for which the p value was 0.027.
    UNASSIGNED: An increase in the TNF-α concentration with increasing clinical stage suggested a role for TNF-α in the spread of OSMF involvement in anatomical structures of the oral cavity and oropharynx. No significant difference in salivary TNF-α levels was noted among the OSMF, SCC and control groups.
    UNASSIGNED: The study showed a positive correlation of TNF-α with increasing stages of OSMF but was not a reliable biomarker in the categorization of the same.

    慢性鼻窦炎(CRS)是一种以鼻腔和鼻旁腔炎症为特征的疾病。这是一种广泛的疾病,对患者具有相当高的发病率。慢性鼻窦炎的当前治疗包括适当的药物治疗,然后对药物耐药的患者进行手术。虽然口服类固醇是有效的,它们与显著的发病率有关,停药后疾病复发很常见。因此需要开发额外的类固醇保留疗法。美沙拉嗪是一种常用的治疗炎症性肠病,与慢性鼻窦炎有着相似的疾病特征。这项探索性体外研究旨在调查美沙拉嗪是否可以重新用于鼻腔冲洗,对人类鼻上皮细胞是安全的,并保留其抗炎作用。收集CRS患者的人鼻上皮细胞(HNEC)。HNEC在气液界面(ALIs)和单层中生长,并用美沙拉嗪或非药物对照进行攻击。跨上皮电阻,细胞旁通透性,测量和毒性以评估上皮的完整性和安全性。使用人白血病单核细胞系(THP-1)分析了美沙拉嗪对白细胞介素(IL)-6和肿瘤坏死因子α(TNF-α)释放的抗炎作用。美沙拉嗪不影响HNEC-ALI的屏障功能,并且在浓度高达20mM的情况下应用于HNEC或THP-1细胞时无毒。0.5和1mM浓度的美沙拉嗪可显着抑制THP-1细胞释放TNF-α。美沙拉嗪可有效减少THP-1细胞分泌的TNF-α,表明其抗炎特性的可能性。剂量高达20mM的美沙拉嗪的安全性特征表明,当局部应用于HNEC时,它是安全的。
    Chronic rhinosinusitis (CRS) is a disease characterised by the inflammation of the nasal and paranasal cavities. It is a widespread condition with considerable morbidity for patients. Current treatment for chronic rhinosinusitis consists of appropriate medical therapy followed by surgery in medically resistant patients. Although oral steroids are effective, they are associated with significant morbidity, and disease recurrence is common when discontinued. The development of additional steroid sparing therapies is therefore needed. Mesalazine is a commonly used therapeutic in inflammatory bowel disease, which shares a similar disease profile with chronic rhinosinusitis. This exploratory in vitro study aims to investigate whether mesalazine could be repurposed to a nasal wash, which is safe on human nasoepithelial cells, and retains its anti-inflammatory effects. CRS patients\' human nasal epithelial cells (HNECs) were collected. HNECs were grown at an air-liquid interface (ALIs) and in a monolayer and challenged with mesalazine or a non-medicated control. Transepithelial electrical resistance, paracellular permeability, and toxicity were measured to assess epithelial integrity and safety. The anti-inflammatory effects of mesalazine on the release of interleukin (IL)-6 and tumour necrosis factor alpha (TNF-α) were analysed using human leukemia monocytic cell line (THP-1). mesalazine did not impact the barrier function of HNEC-ALIs and was not toxic when applied to HNECs or THP-1 cells at concentrations up to 20 mM. mesalazine at 0.5 and 1 mM concentrations significantly inhibited TNF-α release by THP-1 cells. mesalazine effectively decreases TNF-α secretion from THP-1 cells, indicating the possibility of its anti-inflammatory properties. The safety profile of mesalazine at doses up to 20 mM suggests that it is safe when applied topically on HNECs.

    背景:肌肉减少症是老年人常见的一种有害疾病,目前尚无治疗方法。已知肿瘤坏死因子(TNF)样弱凋亡诱导剂(TWEAK)及其受体成纤维细胞生长因子诱导型14(FN14)在肌肉减少症的发病机理中起重要作用。这项研究调查了TWEAK和Fn14中甲基化的改变,以确定管理肌肉减少症的潜在靶标。
    方法:通过流行病学调查,我们通过亚硫酸氢盐测序检测了新疆社区居住的老年人TWEAK和Fn14中CpG岛(CpG)的甲基化。通过焦磷酸测序在152名老年个体中选择与肌肉减少症相关的显著CpG进行检测。CpG甲基化之间的关联,血浆炎症标志物水平,和肌少症进行了分析。
    结果:在60个人中检测到TWEAK中的38个CpG和Fn14中的30个CpG,与对照个体相比,6个CpG在少肌症患者中显示出较低的甲基化。在152名老年人中,带有年龄调整的协方差分析,性别,甘油三酯水平,肥胖,糖尿病,和高血压显示6个CpGs的甲基化水平(TWEAK的CpG8,CpG12,CpG13,CpG20和CpG21,肌肉减少症患者的Fn14)和CpG24显着低于对照组。随着对其他混杂因素的调整,协变量方差分析显示,血浆TWEAK,肌肉减少组TNF-α和IL-10水平明显高于对照组(P=0.007,P<0.001,P=0.003)。多因素logistic回归分析显示,CpG8、CpG13、CpG21和TWEAK的总甲基化(OR=0.767,95%CI=0.622-0.947;OR=0.740,95%CI=0.583-0.941;OR=0.734,95%CI=0.561-0.958;OR=0.883,95%CI=0.795-0.980;CpG22和总甲基化分别与0.0.0.0.从偏相关分析来看,血浆TWEAK与血浆TNF-α相关(r=0.172,P=0.042)。
    结论:新疆社区老年人群肌肉减少症与TWEAK低甲基化和TWEAK及其下游炎症因子TNF-α血浆水平升高有关。
    BACKGROUND: Sarcopenia is a harmful condition common among older adults for which no treatment is available. Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) and its receptor fibroblast growth factor inducible 14 (FN14) are known to play important roles in the pathogenesis of sarcopenia. This study investigated alterations in methylation in TWEAK and Fn14 to identify potential targets for the managing sarcopenia.
    METHODS: Through an epidemiological investigation, we detected methylation of CpG islands (CpGs) in TWEAK and Fn14 in community-dwelling older adult of Xinjiang by bisulfite sequencing. Significant CpGs associated with sarcopenia were selected for detection in 152 older individuals by pyrosequencing. Associations between CpG methylation, plasma inflammatory marker levels, and sarcopenia were analyzed.
    RESULTS: Of 38 CpGs in TWEAK and 30 CpGs in Fn14 detected in 60 individuals, 6 CpGs showed lower methylation in sarcopenia patients compared with control individuals. In 152 older adults, covariance analysis with adjustment for age, gender, triglyceride level, obesity, diabetes, and hypertension showed that the methylation levels of 6 CpGs (CpG8, CpG12, CpG13, CpG20 and CpG21of TWEAK, and CpG24 of Fn14) were significantly lower in sarcopenia patients than in control individuals. With adjustment for additional confounding factors, covariate variance analysis showed that plasma TWEAK, TNF-α and IL-10 levels in the sarcopenia group were significant higher than those in the control group (P = 0.007, P < 0.001, P = 0.003). Multivariate logistic regression analysis showed that CpG8, CpG13, CpG21, and total methylation of TWEAK (OR = 0.767, 95 % CI = 0.622-0.947; OR = 0.740, 95 % CI = 0.583-0.941; OR = 0.734, 95 % CI = 0.561-0.958; OR = 0.883, 95 % CI = 0.795-0.980) as well as CpG22 and total methylation of Fn14 were significantly associated with sarcopenia (OR = 826, 95 % CI = 0.704-0.968; OR = 0.918, 95 % CI = 0.852-0.989). From partial correlation analysis, plasma TWEAK was correlated with plasma TNF-α (r = 0.172, P = 0.042).
    CONCLUSIONS: Sarcopenia is associated with hypomethylation of TWEAK and increased plasma levels of TWEAK and its downstream inflammatory factor TNF-α in a community-dwelling population of older adults in Xinjiang.

    背景:白癜风是一种常见的色素脱失障碍,其特征是皮肤上有明确的白色斑块,影响约0.5%至2%的普通人群。遗传关联研究已经确定了几种易感基因和单核苷酸多态性(SNP)与白癜风发病机理有关;尽管如此,报告经常相互矛盾,很少有结论。考虑到迄今为止发表的所有研究,这项综合荟萃分析研究旨在评估亚洲人群中白癜风风险变异对白癜风病因和协变量分层风险的影响。
    方法:我们进行了系统而全面的搜索,以使用特定的关键词在PubMed中确定相关的白癜风相关候选基因关联研究。数据提取后,我们计算过,对于所涉及的变体,研究水平未调整比值比(OR),标准误差(SE),和95%置信区间(95%CI),通过使用加性逻辑回归,使用R软件包的显性效应和隐性模型(R,3.4.2)\'metafor\'。使用对亚组特异性基因型计数的疾病状态的逻辑回归(广义线性模型;\'glm\')进行亚组分析。为了更好地理解通过荟萃分析获得的白癜风相关变异的可能生物学功能,在计算机功能分析中,通过标准的公开可用的网络工具,也进行了。
    结果:在我们的研究中分析了关于11个SNP的31个白癜风相关病例对照研究。在固定效应荟萃分析中,TNF-α基因上游的一个变异:rs1800629被发现与白癜风风险相关(p=.4.26E-06),显性模型(p=1.65E-7)和隐性模型(p=.000453)。在Benjamini-Hochberg错误发现率(FDR)校正后,在显性(padj=1.82E-6)和隐性模型(padj=.0049)中,rs1800629/TNFα在5%FDR下显着。计算机表征显示,优先变体本质上是调节性的,因此有可能有助于白癜风的发病机理。
    结论:我们的研究构成了对整个亚洲人群报道的基于候选基因的关联研究的首次综合荟萃分析,然后进行白癜风相关变异的计算机模拟分析。根据我们的研究结果,TNF-α单核苷酸变异体,rs1800629G>A有风险关联,亚洲人群可能导致白癜风发病。
    BACKGROUND: Vitiligo is a common depigmentation disorder characterized by defined white patches on the skin and affecting around 0.5% to 2% of the general population. Genetic association studies have identified several pre-disposing genes and single nucleotide polymorphisms (SNPs) for vitiligo pathogenesis; nonetheless, the reports are often conflicting and rarely conclusive. This comprehensive meta-analysis study was designed to evaluate the effect of the risk variants on vitiligo aetiology and covariate stratified vitiligo risk in the Asian population, considering all the studies published so far.
    METHODS: We followed a systematic and comprehensive search to identify the relevant vitiligo-related candidate gene association studies in PubMed using specific keywords. After data extraction, we calculated, for the variants involved, the study-level unadjusted odds ratio, standard errors, and 95% confidence intervals by using logistic regression with additive, dominant effect, and recessive models using R software package (R, 3.4.2) \"metafor.\" Subgroup analysis was performed using logistic regression (generalized linear model; \"glm\") of disease status on subgroup-specific genotype counts. For a better understanding of the likely biological function of vitiligo-associated variant obtained through the meta-analysis, in silico functional analyses, through standard publicly available web tools, were also conducted.
    RESULTS: Thirty-one vitiligo-associated case-control studies on eleven SNPs were analysed in our study. In the fixed-effect meta-analysis, one variant upstream of TNF-α gene: rs1800629 was found to be associated with vitiligo risk in the additive (p = 4.26E-06), dominant (p = 1.65E-7), and recessive (p = 0.000453) models. After Benjamini-Hochberg false discovery rate (FDR) correction, rs1800629/TNF-α was found to be significant at 5% FDR in the dominant (padj = 1.82E-6) and recessive models (padj = 0.0049). In silico characterization revealed the prioritized variant to be regulatory in nature and thus having potential to contribute towards vitiligo pathogenesis.
    CONCLUSIONS: Our study constitutes the first comprehensive meta-analysis of candidate gene-based association studies reported in the whole of the Asian population, followed by an in silico analysis of the vitiligo-associated variant. According to the findings of our study, TNF-α single nucleotide variant rs1800629G>A has a risk association, potentially contributing to vitiligo pathogenesis in the Asian population.

    除IL-5外,其他11种炎性细胞因子的表达水平在偏头痛亚组之间没有显着差异。比较有头痛症状的脑炎组和无头痛症状的肺炎组血清IL-4、TNF-α水平,IL-17A,偏头痛组IL-12p70高于肺炎组,IL-12p70水平高于脑炎组(p<0.05)。血清IL-12p70(OR=1.267,95CI1.054-1.523,p=0.012)和IL-17A(OR=1.066,95CI1.016-1.119,p=0.010)水平升高对偏头痛有显著影响。
    血清IL-12p70和IL-17A水平升高可能会增加儿童偏头痛的风险,具有一定的诊断和预测价值。
    UNASSIGNED: To compare the serum levels of 12 cytokines in migraine group, encephalitis with headache symptoms group, pneumonia without headache symptoms group and migraine subgroups to explore the cytokines associated with migraine in children and their levels.
    UNASSIGNED: A total of 44 children with migraine, 27 children in the encephalitis group with headache symptoms and 44 children in the pneumonia group without headache symptoms were selected from January 2022 to August 2023 in Hebei Children\'s Hospital. They were all tested for serum cytokines by immunofluorescence assay. The migraine group was further divided into subgroups according to different age, gender, course of disease, and presence of coinfection. The differences of serum cytokine levels among the above groups were compared, and the correlation analysis was carried out.
    UNASSIGNED: Except IL-5, there were no significant differences in the expression levels of other 11 inflammatory cytokines between migraine subgroups. Compared with encephalitis with headache symptoms group and pneumonia without headache symptoms group the serum levels of IL-4, TNF-α, IL-17A, and IL-12p70 were higher in migraine group than in pneumonia group, and the levels of IL-12p70 were higher than those in encephalitis group (p < 0.05). An increase in serum IL-12p70 (OR = 1.267, 95%CI 1.054-1.523, p = 0.012) and IL-17A (OR = 1.066, 95%CI 1.016-1.119, p = 0.010) levels had a significant effect on migraine.
    UNASSIGNED: Elevated serum levels of IL-12p70 and IL-17A may increase the risk of migraine in children, which has certain diagnostic and predictive value.

    背景:改善胎儿炎症反应综合征(FIRS)的无创性产前诊断可以帮助评估产前风险并降低围产期结局。这项研究旨在确定阴道收集的羊水中的可溶性尿激酶型纤溶酶原激活物受体(suPAR)对于在妊娠34周前早产胎膜早破后鉴定FIRS是否具有重要意义。
    方法:这是一项前瞻性队列研究,对妊娠22-34+6周早产胎膜早破后的114名孕妇及其新生儿进行了研究。在阴道收集的羊水中使用酶联免疫吸附测定法评估SuPAR。根据FIRS的存在或不存在对患者进行分类。FIRS定义为脐带血白细胞介素-6水平>11pg/mL或组织学心肌炎。使用R包(R-4.0.5)分析数据。
    结果:在所有羊水样本中均检测到SuPAR,中位数为26.23ng/mL(四分位距(IQR),15.19-51.14)。FIRS组suPAR的中位数水平高于非FIRS组,32.36ng/mL(IQR,17.27-84.16)vs.20.46ng/mL(IQR,11.49-36.63)(P=0.01),分别。组织学绒毛膜羊膜炎的存在显着增加了FIRS组的suPAR浓度(P<0.001)。FIRS和FIRS伴组织学绒毛膜羊膜炎的曲线下面积分别为0.65和0.74,最佳截断值为27.60ng/mL。控制胎龄,suPAR的截止值超过27.60ng/mL,预测FIRS的几率高3倍,FIRS伴组织学绒毛膜羊膜炎的几率高6倍.
    结论:阴道羊水中的可溶性尿激酶型纤溶酶原激活剂受体可能有助于评估妊娠34周前早产胎膜早破后患者的产前FIRS风险。
    BACKGROUND: Improving noninvasive antenatal diagnosis of fetal inflammatory response syndrome (FIRS) can assist in the evaluation of prenatal risk and reduce perinatal outcomes. This study aimed to determine whether soluble urokinase-type plasminogen activator receptor (suPAR) in vaginally collected amniotic fluid is significant in identifying FIRS after preterm premature rupture of membranes before 34 weeks of gestation.
    METHODS: This was a prospective cohort study of 114 pregnant women and their newborns after preterm premature rupture of membranes at 22-34+6 weeks of gestation. SuPAR was evaluated using an enzyme-linked immunosorbent assay in vaginally collected amniotic fluid. Patients were classified according to the presence or absence of FIRS. FIRS was defined by umbilical cord blood interleukin-6 level > 11 pg/mL or histological funisitis. The data were analyzed using the R package (R-4.0.5).
    RESULTS: SuPAR was detected in all amniotic fluid samples with a median of 26.23 ng/mL (interquartile range (IQR), 15.19-51.14). The median level of suPAR was higher in the FIRS group than in the non-FIRS group, 32.36 ng/mL (IQR, 17.27-84.16) vs. 20.46 ng/mL (IQR, 11.49-36.63) (P = 0.01), respectively. The presence of histological chorioamnionitis significantly increased the suPAR concentration in the FIRS group (P < 0.001). The areas under the curve for FIRS and FIRS with histological chorioamnionitis were 0.65 and 0.74, respectively, with an optimum cutoff value of 27.60 ng/mL. Controlling for gestational age, the cutoff of suPAR more than 27.60 ng/mL predicted threefold higher odds for FIRS and sixfold higher odds for FIRS with histologic chorioamnionitis.
    CONCLUSIONS: Soluble urokinase-type plasminogen activator receptor in vaginally obtained amniotic fluid may assist in evaluating prenatal risk of FIRS in patients after preterm premature rupture of membranes before 34 weeks of gestation.
