Objective To study the protective effect of resveratrol on lung tissue of respiratory syncytial virus(RSV) bronchiolitis mice by regulating TLR4/NF-κB pathway. Methods Thirty mice were randomly divided into control group, RSV group and resveratrol group. The mice models of RSV bronchiolitis were established, and the changes of TLR4 and NF-κB levels in lung tissues of mice were detected. HE staining and ELISA were used to detect airway inflammation, IL-6 and TNF-α levels before and after resveratrol administration. TLR4 and NF-κB protein and gene expressions were detected by Western Blot and real-time quantitative PCR. Results Compared with the control group, the levels of TLR4 and NF-κB in the lung tissues of mice with bronchiolitis were significantly increased. Airway inflammatory cell infiltration was aggravated in HE staining of lung tissue sections, and inflammatory factors IL-6 and TNF-α were significantly increased showing by ELISA. The expressions of TLR4 and NF-κB in resveratrol group were down-regulated after treatment. Conclusions Resveratrol can inhibit the release of inflammatory factors by inhibiting the TLR4/NF-κB pathway, play a protective role in mice with bronchiolitis.

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.

Objective To summarize the diagnostic experiences of blastic plasmacytoid dendritic cell neoplasm (BPDCN) based on the study of its clinicopathological features and immunophenotypes. Methods The clinical data of 2 patients with BPDCN were collected, the structure alteration and cell morphology were observed by HE staining, the immunophenotype of tumor cells were studied by immunohistochemistry staining and flow cytometry was adopted to confirm the bone marrow involvement. Results Two patients, one of whom was a 97 year-old female, presented with cutaneous ecchymosis nodules as the first symptom. The epidermis, but not the dermal, was diffusedly infiltrated by tumor cells, which were medium-sized with irregular nuclei without prominent nucleoli. The other case was a 69 year-old male with lymph node enlargement as the first symptom. The skin was normal, but the lymph nodes were invasively destroyed by tumor cells, which were medium-sized blast-like with prominent nucleoli. The immunophenotypes of the two patients were both positive for CD123, CD4, CD56 and TDT, but negative for B, T lymphocyte derived and myeloid origin markers, both of which involved bone marrow. Conclusions BPDCN is a rare form of hematological neoplasm, skin symptoms or lymph node enlargement may be presented as the initial symptom, the clinical course were highly aggressive with high frequency of bone marrow involvement. The blastic-like lymphoma and leukemia entities should be considered into account for differential diagnose. The precise diagnosis of BPDCN should be established by integrating histomorphology, immunophenotype and clinical presentation information comprehensively.

目的 探讨血沉(ESR)对川崎病(KD)冠状动脉病变(CAL)的预测价值。方法 收集 2017 年 5 月— 2021 年 6 月收治入院的KD患儿的临床资料,分析ESR对KD患儿CAL发生的预测作用。结果 纳入272例KD患儿,70例KD患儿合并CAL,202例KD患儿无CAL。KD患儿的ESR升高。单因素分析提示CAL组的ESR低于非CAL组,差异有统计学意义(P＜0.05)。ROC曲线下的面积为0.586,提示ESR可作为CAL的预测因子(P＜0.05)。ESR预测川崎病冠脉病变发生的临界值为76.5 mm/h。二分类Logistic回归分析显示,ESR是KD患儿发生CAL的独立危险因素(P＜0.05),当ESR＜76.5 mm·h^-1时,KD患儿CAL发生风险增加 (OR=2.38,95% CI: 1.25~4.53)。结论 KD急性期的ESR水平可用于预测KD患儿CAL的发生,ESR＜76.5 mm·h^-1时,提示KD患儿可能会出现CAL。

Objective To investigate the predictive value of erythrocyte sedimentation rate (ESR) on coronary artery lesions (CAL) in Kawasaki disease (KD). Methods Clinical data of children with KD admitted to the hospital from May 2017 to June 2021 were collected to analyze the predictive value of ESR on the occurrence of CAL in children with KD. Results Of the 272 enrolled children with KD, 70 children with CAL and 202 children without CAL. ESR was significantly higher in children with KD. Univariate analysis suggested that ESR was lower in the CAL group than in the non-CAL group, and the difference was statistically significant (P<0.05). The area under the ROC curve was 0.586, suggesting that ESR could be a predictor of CAL (P<0.05). The critical value of ESR for predicting the occurrence of CAL in KD was 76.5 mm/h. Dichotomous Logistic regression analysis showed that ESR was an independent risk factor for the development of CAL in children with KD (P<0.05), and the risk of CAL in children with KD was significantly increased when ESR was<76.5 mm/h. (OR = 2.38, 95% CI: 1.25-4.53). Conclusions ESR levels in the acute phase of KD can be used to predict the development of CAL in children with KD, and ESR <76.5 mm/h suggests that children with KD may develop CAL.
