以羊水中粒细胞集落刺激因子预测绒毛膜羊膜炎的价值

目的：通过检测分娩时羊水中GCSF和IL-6的含量及其与病理诊断为绒毛膜羊膜炎（CAM）的关系，研究测定羊水中G-CSF和IL-6的含量用以预测CAM的价值。方法：将研究对象按是否胎膜早破分为两组，均排除产科并发症及内外科合并症。两组产妇于分娩时抽取羊水5ml,用ELISA法检测羊水中G-CSF和IL-6的含量，同时两组产妇均于产后留取胎膜，用HE染色法检测是否存在CAM。结果：胎膜早破（PROM）组与对照组在年龄、孕周间差异无显著性的条件下，PROM组羊水中G-CSF和IL-6的含量高于对照组，差异有显著性，并且随着破膜时间延长而增高，各组间差异有显著性；CAM组羊水中G-CSF和IL-6的含量高于非CAM组，并且随着病理级别的增加，羊水中G-CSF和IL-6的的含量增加，其水平高低和胎盘炎症的组织学分级有明显的线性关系，组间差异有显著性；G-CSF与IL-6相比有较高的敏感性和特异性。结论：羊水中C-CSF、IL-6可作为CAM的早期诊断指标，且G-CSF优于IL-6。羊水中G-CSF、IL-6可作为反映绒毛膜羊膜炎严重程度的指标。

Association between interleukin-10 genetic polymorphisms and risk of primary open angle glaucoma in a Chinese Han population: a case-control study

AIM: To investigate the association between interleukin-10 (IL-10) genetic polymorphisms and risk of POAG through a case-control study in a Han population of China. METHODS: A total of 210 patients with POAG and 420 normal subjects were recruited during the period from Dec. 2013 to Dec. 2016. The IL-10 -1082A>G (rs1800870), -819T>C (rs1800871) and -592C>A (rs1800872) polymorphisms were determined using iPlex GOLD SNP genotyping analysis (the SequenomMassARRAY® System, Sequenom, San Diego, USA). The association between IL-10 -1082A>G (rs1800870), -819T>C (rs1800871), and -592C>A (rs1800872) polymorphisms and risk of POAG was assessed by singlelogistic regression analysis. RESULTS: We observed that those carrying the CC genotype of rs1800871 was associated with an increased risk of POAG when compared with those harboring the TT genotype (OR=1.84, 95%CI=1.01-3.38). Those with AA genotype of rs1800872 had a 10.62 fold risk of POAG in comparison to the CC genotype (OR=10.62, 95%CI, 3.41-33.09). A completely linkage disequilibrium was found between IL-10 rs1800871-rs1800872 (D’=1.00, r2=0.16). The A-C-A (OR=2.60, 95%CI, 1.48-4.58) and G-T-A (OR=2.34, 95%CI, 1.42-3.86) haplotypes were associated with an increased risk of POAG, while the A-T-C haplotype showed a decreased risk of POAG (OR=0.63, 95%CI, 0.49-0.81). CONCLUSION: Our data suggest that IL-10 rs1800871 and rs1800872 can be predictive factors for the pathogenesis of POAG in the Chinese population.     

早产儿支气管肺发育不良出院后随访管理专家共识

支气管肺发育不良（bronchopulmonary dysplasia，BPD）是早产儿常见的慢性肺部疾病，严重影响其生存质量。BPD不仅威胁早产儿生命，还可能留有严重后遗症，比如喂养困难、反复下呼吸道感染、气道高反应性疾病、生长发育迟缓及神经发育迟缓等。为了进一步规范BPD早产儿出院后的随访管理，海峡两岸医药卫生交流协会新生儿学专业委员会新生儿循证医学学组基于国内外临床证据，结合临床实践经验，主要从BPD早产儿出院后呼吸系统疾病、生长发育、肺动脉高压、神经发育不良、代谢性骨病及疫苗接种的随访与管理等方面制定了该专家共识。 用格式：引用格式:中国当代儿科杂志，2022，24（5）：455-465

IL-1 receptor-associated kinase 1 participates in the modulation of the NLRP3 inflammasome by tumor-associated macrophages in hepatocellular carcinoma

BackgroundHepatocellular carcinomas (HCCs) occur frequently in the digestive system and are associated with high mortality. This current study examined the regulatory relationship between interleukin (IL)-1 receptor-associated kinase 1 (IRAK1), NLR family pyrin domain-containing 3 (NLRP3) inflammasomes, and tumor-associated macrophages (TAMs) in the growth and metastasis of HCC.MethodsThe expression of IRAK1 and NLRP3 was assessed in tissues and cells via quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analysis. Immunohistology was performed to detect the macrophage markers CD68, CD163, and CD168 in tumor tissues. Small interfering (si)RNA targeting IRAK1 (si-IRAK1) was designed to silence IRAK1 expression. Following si-IRAK1 transfection and/or co-culture with TAMs, HCC cell viability, proliferation, migration, and invasion, as well as the expression of NLRP3 and pro-inflammatory cytokines IL-1 β, IL-18, and monocyte chemotactic protein 1 (MCP-1) were assessed.ResultsHCC tissues showed elevated expression of IRAK1 and NLRP3, as well as increased expression of the macrophage markers CD68, CD163, and CD168, compared to adjacent healthy tissues. Silencing of IRAK1 expression in HepG2 and Huh7 cells resulted in suppression of cell proliferation, migration, and invasion, and also reduced expression of NLRP3 and the pro-inflammatory cytokines IL-1β, IL-18, and MCP-1. Moreover, TAMs promoted HepG2 and Huh7 cell proliferation, migration, and invasion, and elevated the expression of NLRP3, IL-1β, IL-18, and MCP-1. Furthermore, IRAK1 silencing reversed the effects of TAMs on HepG2 and Huh7 cells.ConclusionsThe expression of IRAK1 was associated with HCC growth and metastasis, as well as NLRP3 inflammasome activation. The ability of TAMs to promote HCC growth and metastasis may be activated by NLRP3 inflammasomes and regulated by IRAK1.
