目的 研究SOCS6/STAT6通路在前列腺细胞炎性增殖作用中的调控作用。方法 使用人前列腺细胞株RWPE-1建立炎症模型,将细胞分为对照(CON)组和炎症刺激(INF)组,后者通过添加脂多糖(LPS)模拟炎症环境。采用ELISA检测白细胞介素-1β(IL-1β)-1β、白细胞介素-6(IL-6)和白细胞介素-8(IL-8)表达水平,蛋白免疫印迹法检测细胞因子信号抑制物-6(SOCS6)、信号转导和转录激活因子-6(STAT6)及磷酸化STAT6蛋白的表达水平。结果 经过LPS处理后,RWPE-1细胞中的SOCS6蛋白表达水平显著下降(P<0.01),而磷酸化STAT6表达水平上升(P<0.01)。结论 SOCS6/STAT6通路可能通过调节炎症环境下STAT6的磷酸化水平,参与调节前列腺细胞的炎性增殖作用。
Objective To explore the regulatory role of SOCS6/STAT6 pathway in the inflammatory proliferation of prostate cells.Methods The human prostate cell line RWPE-1 was used to establish an inflammation model.Cells were divided into a control(CON)group and an inflammation-stimulated(INF)group,with the latter subjected to lipopolysaccharide(LPS)treatment to simulate an inflammatory environment.The expression levels of interleukin(IL)-1β、IL-6 and IL-8 were detected by ELISA,and the expression levels of suppressor of cytokine signaling 6(SOCS6),signal transducer and activator oftranscription-6,(STAT6),and phosphorylated STAT6 proteins were detected by Western blot.Results The results showed that after LPS treatment,the expression of SOCS6 protein in RWPE-1 cells significantly decreased,while the expression of phosphorylated STAT6 increased.Conclusions The SOCS6/STAT6 pathway may be involved in regulating the inflammatory proliferation of prostate cells by modulating the phosphorylation level of STAT6 under inflammatory conditions.

Objective Exploring the significance of immunohistochemical staining with streptavidin-perosidase(SP)to detect the expression of insulin-like growth factor-1(IGF-1)and tissue P53 in colorectal adenocarcinoma.Methods A total of 169 patients with colorectal adenocarcinoma admitted to a hospital from January 2020 to December 2023 were selected and divided into the malignant group.Other 169 patients with benign colorectal tumors admitted to a hospital during the same period were selected and divided into the benign group.SP immunohistochemistry staining was used to detect and compare the expression levels of IGF-1 and P53 proteins in two groups of tumor tissues obtained in surgery or biopsy.And the IGF-1 levels,IGF-1 mRNA,and P53 positivity rates in patients with different clinical stages,lymph node metastasis,and tissue differentiation levels were compared.Results There was a significant difference in the positive rates of IGF-1mRNA and P53 detected by SP immunohistochemistry staining,and malignant group(72.78%,47.93%)were higher than the benign group(14.79%,6.51%),which were statistically significant(χ2=115.440,73.180,P<0.05).The positive rates of IGF-1 and P53 were 96.77% and 77.42% in stage IV,which were higher than those in Stage III(85.11%,63.83%),II(62.69%,31.34%)and I(45.83%,25.00%),the differences were statistically significant(χ2=24.860,28.000,P<0.05).The expression levels of IGF-1 and P53 in colorectal adenocarcinoma patients with different lymph node metastases showed significant differences,the positive rates of IGF-1(85.71%)and P53(71.43%)in patients with lymph node metastasis were higher than those without lymph node metastasis(14.79%,40.94%),and the differences were statistically significant(χ2=4.720,11.740,P<0.05).There were significant differences in the expression levels of IGF-1 and P53 among patients with colorectal adenocarcinoma of different degrees of differentiation,the positive rates of IGF-1(93.48%)and P53(71.74%)were significantly higher than those of moderately differentiated(81.18%,54.12%)and well differentiated(52.63%,31.58%),and the differences were statistically significant(χ2=21.250,13.510,P<0.05).Conclusion sThrough SP immunohistochemical staining,it was found that the positivity rates of IGF-1 and P53 in colorectal adenocarcinoma patients were higher than those in benign tumor patients,and those with high the clinical stage,lymph node metastasis,and low differentiation of tumor tissue,had higher the positivity rates of IGF-1 and P53.Therefore,IGF-1 and P53 are expected to become important monitoring indicators for the diagnosis and treatment of colorectal adenocarcinoma.

N6-甲基腺苷(N6-methyladenosine, m6A)修饰是真核生物信使 RNA中最丰富的表观遗传修饰,其失调会导致mRNA异常生物学行为如翻译和降解紊乱,从而调控肿瘤发生发展。近期研究表明m6A在免疫调控过程中可发挥重要作用,其不仅可调节免疫细胞的活化,还在肿瘤微环境中免疫应答发挥重要调控作用,从而影响免疫治疗效果。越来越多的证据表明m6A修饰可能是肿瘤免疫治疗的重要潜在干预靶点。本文阐述了免疫细胞中m6A修饰调控及其在肿瘤免疫微环境中相关调节作用,并进一步探讨了靶向m6A调控蛋白在肿瘤免疫治疗中的干预策略及潜在治疗价值。
N6-methyladenosine (m6A) modification is the most abundant epigenetic modification in eukaryotic messenger RNA (messenger RNA). Its dysregulation drives abnormal transcription and translation processes, which promotes the occurrence and development of tumors. Studies have shown that m6A modification can regulate the activation of immune cells and their infiltration into the tumor microenvironment (TME), which may affect the efficiency of immunotherapy. Therefore, m6A modification may be a potential target for tumor immunotherapy. This paper describes the modification of m6A in immune cells and the antitumor immune response associated with TME, and explores the potential therapeutic value of targeting m6A regulators in tumor immunotherapy.

自身免疫性肝炎(AIH)是由不明原因免疫异常引起的急性或慢性肝脏炎症性疾病,不分年龄或性别,影响所有种族群体。AIH如果没有得到及时的治疗,可能会发展为肝硬化、肝衰竭,甚至导致死亡。目前一些诊断评分系统和肝活组织病理检查已成为诊断的标准,然而由于疾病表现的高度异质性,AIH诊断仍很有挑战性。大多数患者最初对一线治疗(糖皮质激素与硫唑嘌呤的联合治疗)有应答,然而,应答欠佳和因不良反应引起的不耐受也不少见,需要二线和(或)三线治疗。本文总结阐述诊断困难、一线药物治疗应答欠佳或不耐受的疑难AIH诊断和管理的最新进展,并归纳了目前国内外关于AIH治疗的新方法,为AIH的临床诊疗提供参考。
Autoimmune hepatitis(AIH)is an acute or chronic inflammatory disease of liver caused by unclear immune response that affects people from all ethnic groups irrespective of age or sex.If left untreated,AIH will lead to cirrhosis,liver failure,or death.A number of diagnostic scoring systems and histopathological examination of liver biopsies are now the standard for diagnosis.However,due to the high heterogeneity of the disease presentation,AIH diagnosing remains challenging.Most patients initially respond to first-line treatment,which is corticosteroids combined with azathioprine.However,insufficient response and intolerance due to side effects are also common,so some patients requires second-and/or third-line therapies.Here we summarized the latest progress in diagnosis and management of AIH with difficult diagnosis,poor response to first-line drug treatment or intolerance,as well as the new methods of AIH treatment worldwide,to provide reference for the clinical diagnosis and treatment of AIH.

严重烧伤后患者免疫功能的失调,易导致创面感染、全身炎症反应综合征、脓毒症、感染性休克等并发症,增加患者病死率。免疫细胞功能适度的活化将有助于烧伤患者抵御外界病原体的侵袭、促进创面的愈合,但功能过度激活或者功能低下,则会引发一系列严重的后果。本文旨在归纳严重烧伤后中性粒细胞、单核/巨噬细胞、肥大细胞、NK细胞及T淋巴细胞等免疫细胞的功能变化与炎症反应之间的关系,为完善烧伤患者诊疗、减少并发症、改善预后提供新的思路。
The imbalance of immune function in severely burned patients can easily lead to wound infection,systemic inflammatory response syndrome,sepsis,septic shock and other complications,which increase the mortality of patients. Moderate activation of immune cell function will help burned patients to resist the invasion of external pathogens and promote wound healing,but excessive activation or low function can lead to a series of serious consequences. The purpose of this paper is to summarize the relationship between the functional changes of immune cells such as neutrophils,monocytes/macrophages,mast cells,NK cells,T lymphocytes and inflammatory reaction after severe burns,and to provide new ideas for improving the diagnosis and treatment of burned patients,reducing complications and improving the prognosis.
