    免疫调节通过减少哺乳动物宿主中炎症诱导的发病率来增强寄生虫的适应性,以及通过减弱针对寄生虫的免疫反应。使用全蛋白质组差异筛选方法,我们确定日本血吸虫蠕虫防御分子(SjHDM-1)作为抗日本血吸虫表达抗体的靶标,但不容易受到影响,个人。在菲律宾日本血吸虫流行地区进行的纵向队列研究(N=644)中,SjHDM-1抗体水平不能预测对再感染的抵抗,但与炎症指标增加相关.与具有低抗SjHDM-1的个体相比,具有高水平的抗SjHDM-1IgG的个体具有更高水平的C反应蛋白。高抗SjHDM-1IgG反应也与营养状况(白蛋白)的生物标志物减少有关。以及营养状况的人体测量学指标(WAZ和HAZ)下降和肝肿大的指标增加。我们的结果表明,抗SjHDM-1反应抑制SjHDM-1的免疫调节功能,导致发病率增加。
    Immunomodulation enhances parasite fitness by reducing inflammation-induced morbidity in the mammalian host, as well as by attenuating parasite-targeting immune responses. Using a whole proteome differential screening method, we identified Schistosoma japonicum Helminth Defense Molecule (SjHDM-1) as a target of antibodies expressed by S. japonicum resistant, but not susceptible, individuals. In a longitudinal cohort study (N=644) conducted in a S. japonicum endemic region of the Philippines, antibody levels to SjHDM-1 did not predict resistance to reinfection but were associated with increased measures of inflammation. Individuals with high levels of anti-SjHDM-1 IgG had higher levels of C-reactive protein compared to individuals with low anti-SjHDM-1. High anti-SjHDM-1 IgG responses were also associated with reduced biomarkers of nutritional status (albumin), as well as decreased anthropometric measures of nutritional status (WAZ and HAZ) and increased measures of hepatomegaly. Our results suggest that anti-SjHDM-1 responses inhibit the immunomodulatory function of SjHDM-1, resulting in increased morbidity.

    我们在这项研究中的目的是,符合研究标准的志愿者29天定期食用平菇水提取物对血液和细胞因子值有影响吗?
    根据研究目的,志愿者被要求每天早上服用100毫升提取物,共29天。在研究的第15天和第29天,从志愿者身上抽取了三管血液样本。进行血液样品的生化和血液学分析,并检查通过细胞因子的免疫调节作用。在使用蘑菇提取物之前从志愿者获得的3管血液中获得的值用作对照。还分析了100毫升蘑菇水提取物的化学组成和β-葡聚糖含量。
    无法检测到IL-4,IL-6,IL-10和IL-13,因为该值低于最低标准值。TNF-α,与第1天(对照)值相比,第15天和第29天的IFN-γ和IL-1β值降低(p<0.05)。然而,在第15天和第29天之间没有观察到显著差异.未观察到生化和血液学值异常。此外,提取物的β-葡聚糖含量为38.12mg/100ml。
    肾脏和肝脏功能检查结果的频率范围证实,骨肉假单胞菌是可靠的食物来源。考虑到细胞因子值,这些结果表明平菇水提取物具有抗炎作用。因为在29天的使用中没有观察到显著差异,据认为,15天的每日消耗提取物可能足以发生抗炎作用。然而,需要大量合格的临床试验来支持这一问题.
    UNASSIGNED: Our aim in this study is, does 29-day regular consumption of Pleurotus ostreatus water extract by volunteer individuals who meet the study criteria have an effect on blood and cytokine values?
    UNASSIGNED: In accordance with the purpose of the study, volunteers were asked to consume 100 ml of the extract every morning for 29 days. Three tubes of blood samples were taken from the volunteers on the 15th and 29th days of the study. Biochemical and hematological analysis of the blood samples were performed and immunomodulatory effects through cytokines were examined. The values obtained from 3 tubes of blood obtained from volunteers before the use of mushroom extract were used as control. The chemical composition and β-glucan content of 100 ml of mushroom water extract were also analyzed.
    UNASSIGNED: IL-4, IL-6, IL-10 and IL-13 could not be detected because the values were below the lowest standard value. TNF-α, IFN-γ and IL-1β 15th and 29th day values decreased compared to the 1st day (control) values (p < 0.05). However, there was no significant difference observed between the 15th and 29th day. No abnormalities were observed in biochemical and hematological values. Also, the β-glucan content of extract was found 38.12 mg/100 ml.
    UNASSIGNED: The frequency range of kidney and liver function test results confirmed that P. osreatus is a reliable food source. Considering the cytokine values these results indicate that P. ostreatus water extract has an anti-inflammatory effect. As no significant difference was observed in 29 days of use, it is thought that 15 days of daily consumption of the extract may be sufficient for the anti-inflammatory effect to occur. However, a large number of qualified clinical trials are needed to support the issue.

    这项研究的目的是研究灭活的痤疮丙酸杆菌和来自大肠杆菌细胞的脂多糖对受猫泛白细胞减少症病毒(FPV)影响的猫的治疗效果。对80只FPV阳性猫进行的回顾性研究分为两组:治疗组接受灭活的痤疮丙酸杆菌和来自大肠杆菌细胞的脂多糖以及支持治疗,而无治疗组仅接受支持治疗。两组白细胞总数无明显差别。然而,两组的白细胞总数在第0天都较低,在第3天和第6天显著增加.此外,与未治疗组相比,治疗组的白细胞计数在第3至6天明显增加(p<0.01)。两组之间的死亡率没有显着差异。在一项前瞻性研究中,检测两组血清和粪便免疫球蛋白A(IgA)水平.两组血清或粪便中的IgA水平没有显着差异。
    The objective of this study was to investigate the therapeutic effects of inactivated Propionibacterium acnes and lipopolysaccharide derived from Escherichia coli cells in cats affected by feline panleukopenia virus (FPV). A retrospective study of 80 FPV-positive cats was divided into two groups: a treatment group receiving inactivated Propionibacterium acnes and lipopolysaccharide derived from Escherichia coli cells along with supportive treatment and a no-treatment group receiving only supportive treatment. There was no significant difference in the total white blood cell counts between the two groups. However, the total white blood cell counts of both groups were low on day 0 and increased significantly on days 3 and 6 of treatment. Additionally, the white blood cell counts in the treatment group significantly increased during days 3 to 6 compared with those of the no-treatment group (p < 0.01). The mortality rate was not significantly different between the two groups. In a prospective study, the serum and fecal immunoglobulin A (IgA) levels were measured in both groups. There were no significant differences in IgA levels between the two groups in either the serum or feces.

    炎症性肠病患者的治疗选择不断发展;然而,药物难治性疾病仍然是一个问题。儿科病例系列显示西罗莫司治疗难治性克罗恩病(CD)的潜在益处;然而,成人患者的数据有限。因此,我们回顾性地确定并报告了4例服用西罗莫司治疗难治性CD的患者的临床结局.尽管西罗莫司治疗的中位持续时间为524天,并且有一些治疗益处,所有患者均因不良反应停止治疗.我们的研究结果表明,虽然西罗莫司可能具有临床效用,其作用可能受到治疗引起的不良反应的限制。
    Treatment options for patients with inflammatory bowel disease are constantly evolving; however, medication-refractory disease remains an issue. Pediatric case series show the potential benefit of sirolimus therapy in refractory Crohn\'s disease (CD); however, limited data exist in adult patients. As such, we retrospectively identified and report clinical outcomes for 4 patients prescribed sirolimus for treatment of refractory CD. Despite a median sirolimus therapy duration of 524 days and some therapeutic benefits, all patients discontinued therapy due to adverse effects. Our findings suggest that while sirolimus may have clinical utility, its role may be limited by treatment-derived adverse effects.

    目的:接受英夫利昔单抗(IFX)治疗的炎症性肠病(IBD)患者通常通过形成抗药物抗体(ADAs)而经历免疫原性反应丧失(LOR)。已知与初始IFX诱导组合使用的免疫调节剂(IMM)减少ADA发展并改善临床结果。我们旨在评估反应性添加IMM对IFX单一疗法患者的影响。
    方法:我们对IBD患者进行了回顾性队列研究和系统评价,并进行了荟萃分析,有或没有临床LOR,有IMM(硫唑嘌呤,6-巯基嘌呤,或甲氨蝶呤)反应性添加(反应性联合疗法;rCT)以对抗升高的ADA并提高IFX水平。使用随机效应模型提取数据用于合并效应大小估计,在IMM启动前后比较了ADA和IFX谷水平。
    结果:我们确定了6例因ADA滴度升高和IFX水平低而接受rCT的患者。中值ADA滴度从506ng/mL(四分位距(IQR)[416-750])降至76.5ng/mL(IQR[25.8-232]),减少85%(p=0.031)。中值IFX波谷从0.4µg/mL(IQR[0.4-0.48])增加到8.25µg/mL(IQR[3.7-9.6]),增加20.6倍(p=0.038)。包括89例患者的7项研究的荟萃分析汇总效应大小显示,ADA滴度降低了87%[95%置信区间(CI)=72-94%],IFX波谷增加6.7倍(95%CI=2.4-18.7),临床缓解抢救率为76%(95%CI=59-93%)。
    结论:这些结果表明,rCT是一种有效的挽救策略,适用于对IFX进行免疫原性LOR以降低ADA滴度的患者,恢复治疗性IFX水平,并重新获得IBD的临床缓解。
    OBJECTIVE: Patients with inflammatory bowel disease (IBD) receiving infliximab (IFX) commonly experience immunogenic loss of response (LOR) by formation of anti-drug antibodies (ADAs). An immunomodulator (IMM) used in combination with initial IFX induction is known to reduce ADA development and improve clinical outcomes. We aimed to assess the impact of reactively adding an IMM to patients on IFX monotherapy.
    METHODS: We conducted a retrospective cohort study and systematic review with meta-analysis of patients with IBD demonstrating immunologic LOR, with or without clinical LOR, that had an IMM (azathioprine, 6-mercaptopurine, or methotrexate) reactively added (reactive combination therapy; rCT) to combat elevated ADAs and raise IFX level. Data were extracted for pooled effect size estimation using random-effects models, and ADA and IFX trough levels were compared pre- and post-IMM initiation.
    RESULTS: We identified 6 patients who received rCT due to rising ADA titers and low IFX levels. Median ADA titer decreased from 506 ng/mL (interquartile range (IQR) [416-750]) to 76.5 ng/mL (IQR [25.8-232]), an 85% decrease (p = 0.031). Median IFX trough increased from 0.4 µg/mL (IQR [0.4-0.48]) to 8.25 µg/mL (IQR [3.7-9.6]), a 20.6-fold increase (p = 0.038). Meta-analysis pooled effect size of 7 studies with 89 patients showed an 87% ADA titer reduction [95% confidence interval (CI) = 72-94%], 6.7-fold increased IFX trough (95% CI = 2.4-18.7), and 76% clinical remission rescue rate (95% CI = 59-93%).
    CONCLUSIONS: These results suggest rCT is a valid rescue strategy in patients with immunogenic LOR to IFX to reduce ADA titers, restore therapeutic IFX levels, and recapture clinical remission of IBD.

    Keytruda(pembrolizumab)是一种免疫调节剂,可防止免疫细胞和肿瘤细胞上的程序性细胞死亡蛋白(PD-1)和程序性死亡配体(PD-L1/2)之间的相互作用,从而防止T细胞功能障碍。有时,对肿瘤细胞产生强烈的免疫反应可能不会放过正常细胞,导致多种多系统不良反应。有了这个,我们介绍了一例64岁男性,他在完成了8个周期的Keytruda治疗去势耐药转移性前列腺癌6个月后发展为急性胰腺炎,在排除所有其他胰腺炎原因后.
    Keytruda (pembrolizumab) is an immunomodulator that prevents the interaction between programmed cell death protein (PD-1) and programmed death ligand (PD-L1/2) on immune cells and tumour cells, thereby preventing T cell dysfunction. At times, mounting a strong immune response against tumour cells may not spare normal cells, leading to a variety of multisystemic adverse effects. With this, we present a case of a 64-year-old male who developed acute pancreatitis after completing eight cycles of Keytruda for castrate-resistant metastatic prostate cancer for six months, after all other causes of pancreatitis were excluded.

    米糠阿拉伯木聚糖化合物(RBAC)是一种具有抗癌特性的天然免疫调节剂。
    这项研究严格评估了有关RBAC生物学途径及其对癌症治疗的影响的现有证据。
    对范围审查的二次分析包括评估RBAC对健康或恶性细胞的机制的研究,动物模型,或人类用于癌症预防或治疗。对生存率和生活质量结局的随机对照试验数据进行荟萃分析。
    证据综合基于38篇文章。RBAC通过促进癌症患者的细胞凋亡和恢复免疫功能来增强炎症和细胞毒性反应以阻断肿瘤发生而表现出抗肿瘤特性。RBAC通过上调药物转运与化疗剂协同作用。在临床试验中,RBAC联合化疗栓塞治疗肝癌疗效改善,降低复发率,和延长生存期。RBAC还增强内源性抗氧化系统以防止氧化应激并防止辐射副作用。此外,RBAC具有化学保护作用。动物和人类已经表现出降低的化疗毒性和副作用。Meta分析表明,RBAC治疗在第一年增加了4.02倍(95%CI:1.67,9.69),在第二年增加了2.89倍(95%CI:1.56,5.35)。
    RBAC是一种天然产品,在癌症治疗中具有巨大潜力。需要额外的研究来表征,量化、并标准化RBAC中负责抗癌作用的活性成分。更精心设计,需要大规模的临床试验来进一步证实治疗效果。
    UNASSIGNED: Rice bran arabinoxylan compound (RBAC) is a natural immunomodulator with anticancer properties.
    UNASSIGNED: This study critically evaluates the available evidence on the biological pathways of RBAC and its effects on cancer treatment.
    UNASSIGNED: This secondary analysis of a scoping review includes studies evaluating the mechanisms of RBAC on healthy or malignant cells, animal models, or humans for cancer prevention or treatment. Data from randomized controlled trials on survival and quality of life outcomes were subjectd to meta analysis.
    UNASSIGNED: The evidence synthesis was based on 38 articles. RBAC exhibited antitumor properties by promoting apoptosis and restoring immune function in cancer patients to enhance inflammatory and cytotoxic responses to block tumorigenesis. RBAC works synergistically with chemotherapeutic agents by upregulating drug transport. In a clinical trial, combining RBAC with chemoembolization in treating liver cancer showed improved response, reduced recurrence rates, and prolonged survival. RBAC also augments the endogenous antioxidant system to prevent oxidative stress and protect against radiation side effects. In addition, RBAC has chemoprotective effects. Animals and humans have exhibited reduced toxicity and side effects from chemotherapy. Meta analysis indicates that RBAC treatment increases the survival odds by 4.02-times (95% CI: 1.67, 9.69) in the first year and 2.89-times (95% CI: 1.56, 5.35) in the second year.
    UNASSIGNED: RBAC is a natural product with immense potential in cancer treatment. Additional research is needed to characterize, quantify, and standardize the active ingredients in RBAC responsible for the anticancer effects. More well-designed, large-scale clinical trials are required to substantiate the treatment efficacies further.

    巨噬细胞,肺部主要的免疫细胞,在维持肺部免疫微环境的微妙平衡中起着关键作用。然而,在慢性炎症性肺病和肺癌中,巨噬细胞表型经历不同的转变,M1为主的巨噬细胞促进炎症损伤和M2为主的巨噬细胞促进癌症进展。外泌体,作为细胞间信号传导和物质交换的关键介质,在肺部炎性疾病和肺癌的发展过程中参与巨噬细胞的病理重塑。具体来说,在炎症性肺部疾病中,外泌体促进巨噬细胞的促炎表型,抑制抗炎表型,随后,重塑的巨噬细胞释放的外泌体进一步加剧了炎症损伤。在癌症中,外泌体促进促肿瘤肿瘤相关巨噬细胞(TAMs);抑制抗肿瘤TAMs;TAMs释放的外泌体进一步增强肿瘤增殖,转移,对化疗有抵抗力.同时,外泌体表现出双重作用,具有传递免疫调节分子和负载治疗剂的潜力,并为在慢性炎症性肺病和肺癌期间恢复巨噬细胞的免疫失调提供了前景。在慢性炎症性肺病中,这表现为外泌体重塑抗炎巨噬细胞,抑制促炎巨噬细胞,减轻重塑后的炎症损伤。在肺癌中,外泌体重塑抗肿瘤巨噬细胞,抑制促肿瘤巨噬细胞,重塑的巨噬细胞分泌外泌体,抑制肺癌的发展。展望未来,基于外泌体的有效和靶向治疗可能成为肺部疾病治疗的一个有希望的方向。
    Macrophages, the predominant immune cells in the lungs, play a pivotal role in maintaining the delicate balance of the pulmonary immune microenvironment. However, in chronic inflammatory lung diseases and lung cancer, macrophage phenotypes undergo distinct transitions, with M1-predominant macrophages promoting inflammatory damage and M2-predominant macrophages fostering cancer progression. Exosomes, as critical mediators of intercellular signaling and substance exchange, participate in pathological reshaping of macrophages during development of pulmonary inflammatory diseases and lung cancer. Specifically, in inflammatory lung diseases, exosomes promote the pro-inflammatory phenotype of macrophages, suppress the anti-inflammatory phenotype, and subsequently, exosomes released by reshaped macrophages further exacerbate inflammatory damage. In cancer, exosomes promote pro-tumor tumor-associated macrophages (TAMs); inhibit anti-tumor TAMs; and exosomes released by TAMs further enhance tumor proliferation, metastasis, and resistance to chemotherapy. Simultaneously, exosomes exhibit a dual role, holding the potential to transmit immune-modulating molecules and load therapeutic agents and offering prospects for restoring immune dysregulation in macrophages during chronic inflammatory lung diseases and lung cancer. In chronic inflammatory lung diseases, this is manifested by exosomes reshaping anti-inflammatory macrophages, inhibiting pro-inflammatory macrophages, and alleviating inflammatory damage post-reshaping. In lung cancer, exosomes reshape anti-tumor macrophages, inhibit pro-tumor macrophages, and reshaped macrophages secrete exosomes that suppress lung cancer development. Looking ahead, efficient and targeted exosome-based therapies may emerge as a promising direction for treatment of pulmonary diseases.
