新生儿期的免疫系统发育阶段对维持新生儿健康至关重要,具有独特的免疫调节机制。近年来,人们越来越关注髓源性抑制细胞（MDSCs）在新生儿免疫调节中的作用。MDSCs是一类免疫抑制功能强大的异质性细胞群体,它们能够通过多种机制调节免疫应答。MDSCs在新生儿中的调节作用对防止过度免疫反应和促进免疫耐受至关重要,有助于预防新生儿期炎症性疾病,并对其后续健康产生积极影响。近期研究文献分析展示了MDSCs在新生儿免疫调节中的多种作用机制,包括在特定病理条件下的保护作用、与新生儿期炎症反应的相互作用,以及对长期免疫发展的潜在影响。因此,深入理解MDSCs在新生儿免疫中的角色,不仅有助于揭示其复杂的调节机制,也为制定新的预防和治疗新生儿炎症性疾病的策略提供了新的思路。

The developmental stage of the immune system during the neonatal period is crucial for maintaining neonatal health,characterized by unique immunoregulatory mechanisms．In recent years,increasing attention has been drawn to the role of myeloid-derived suppressor cells（MDSCs）in neonatal immune regulation．MDSCs represents a heterogeneous population of cells with potent immunosuppressive functions,capable of modulating immune responses through various mechanisms．The regulatory role of MDSCs in neonates is vital for preventing excessive immune reactions and promoting immune tolerance,thereby aiding in the prevention of neonatal inflammatory diseases and positively influencing subsequent health outcomes．Analysis of recent research literature reveals multiple mechanisms through which MDSCs contribute to neonatal immune regulation,including protective effects under specific pathological conditions,interactions with neonatal inflammatory responses,and potential impacts on long-term immune development．Therefore,a comprehensive understanding of the role of MDSCs in neonatal immunity not only helps elucidate their intricate regulatory mechanisms but also provides novel insights for developing strategies for the prevention and treatment of neonatal inflammatory diseases．

Objective To explore the relationship between m6A methylated genes and prognosis of ovarian cancer, so as to provide scientific basis for targeted therapy and prognosis assessment of ovarian cancer. Methods The mRNA expression data of ovarian cancer tissues and normal tissues were downloaded from TCGA and GTEx databases for difference analysis between two groups. The genes related to ovarian cancer survival were screened by LASSO regression, and the risk score prediction model was further constructed by step Cox regression analysis. The patients were divided into high-risk group and low-risk group according to the median risk score, and the ROC was used for analysis. Correlation analysis was performed to construct an expression regulatory network with m6A genes, and GO function enrichment and KEGG pathway analysis were performed to preliminarily explore the potential biological mechanism. Results 20 m6A methylation genes were found in differential expression between cancer tissue and normal tissue, three genes (HNRNPA2B1, ZC3H13, WTAP) were used to construct the model through step Cox regression analysis. Patients' survivals of high-risk group were shortened than that of the low-risk group obviously (P=0.001 9), the risk of death significantly was increased (HR=2.643, P<0.01). After risk score model combined with patient age, clinical classification and stage, the AUC of 1, 3, 5 years was 0.74, 0.64 and 0.64. Bioinformatics analysis indicated that those m6A genes were involved in RNA splicing, localization, transport, metabolic regulation, proteolysis, cell cycle, ribosome synthesis and other biological processes. Conclusion The prognostic risk assessment model of m6A methylated genes for ovarian cancer was successfully constructed and the model had certain predictive efficacy.

Objective To detect the expression of SNCG in ovarian cancer tissue and its clinical significance, to clarify the relationship between the expression of SNCG in human ovarian cancer and the degree of malignancy, so as to provide theoretical basis for the diagnosis, treatment and prognosis of clinical ovarian cancer. Methods From January 2010 to January 2015 in First Affiliated Hospital of Medical College of Shihezi University,119 patients with ovarian cancer and 50 patients with normal ovarian which had complete clinical data and paraffin section were selected. Immunohistochemical method was used to detect ovarian SNCG expression, and the expression of SNCG relationship with clinical pathological characteristics and prognosis of patients with ovarian cancer was analyzed. Results The expression of SNCG in ovarian cancer tissue was significantly higher than that in normal ovarian tissue (χ²=73.575,P＜0.001). SNCG expression was correlated with tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 levels in ovarian cancer patients, and the differences were statistically significant (P＜0.05). It was not correlated with the tumor primary site, ascites, recurrence of ovarian tumor and chemotherapy resistance, and the differences were not statistically significant (P＞0.05).The overexpression of SNCG was correlated with PFS and OS in HGSOC patients, and the differences were statistically significant (P＜0.05). Analysis of multivariate Cox proportional risk model showed that SNCG was an independent prognostic factor in patients with HGSOC, related to PFS (HR=2.107,95%CI: 1.014-3.795,P=0.034) and OS (HR=1.238,95%CI: 0.716-1.928,P=0.047). Conclusion The high expression of SNCG in ovarian cancer is related to tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 expressions, but it is not related to the recurrence of ovarian cancer or chemotherapy resistance. The overexpression of SNCG protein can be used as an independent prognostic factor in patients with HGSOC for clinical diagnosis and treatment guidance.
