The Potential Roles of Dietary Anthocyanins in Inhibiting Vascular Endothelial Cell Senescence and Preventing Cardiovascular Diseases

Cardiovascular disease (CVD) is a group of diseases affecting the heart and blood vessels and is the leading cause of morbidity and mortality worldwide. Increasingly more evidence has shown that the senescence of vascular endothelial cells is the key to endothelial dysfunction and cardiovascular diseases. Anthocyanin is a type of water-soluble polyphenol pigment and secondary metabolite of plant-based food widely existing in fruits and vegetables. The gut microbiome is involved in the metabolism of anthocyanins and mediates the biological activities of anthocyanins and their metabolites, while anthocyanins also regulate the growth of specific bacteria in the microbiota and promote the proliferation of healthy anaerobic flora. Accumulating studies have shown that anthocyanins have antioxidant, anti-inflammatory, and anti-aging effects. Many animal and in vitro experiments have also proven that anthocyanins have protective effects on cardiovascular-disease-related dysfunction. However, the molecular mechanism of anthocyanin in eliminating aging endothelial cells and preventing cardiovascular diseases is very complex and is not fully understood. In this systematic review, we summarize the metabolism and activities of anthocyanins, as well as their effects on scavenging senescent cells and cardioprotection.     

头颈部肿瘤患者自然杀伤细胞活性及计数分析

本文对25例头颈部肿瘤患者的外周血NK细胞杀伤活性及NK细胞计数进行测定，其中有15例患者手术治疗切除肿瘤，于术后三周复查NK活性及NK计数，并与正常人组对照。实验结果显示：头颈部肿瘤患者NK活性及NK计数均低于正常人，两组比较均有极显著性差异（P＜0．01）；术后患者的NK活性比术前有明显提高，配对t检验P＜0．01，NK计数比术前也有所提高，配对t检验P＜0．05，有显著性差异；NK活性的水平与肿瘤的分期有相关性，晚期（T4期）癌症患者NK活性明显低于早期（T1、T2）患者，可以看出NK活性随着肿瘤的发展而降低，肿瘤对宿主有免疫抑制作用；NK活性与NK数量之间无显著的相关性，二者之间的相关系数r＝0．344。     

聚焦超声治疗外阴上皮内非瘤样病变的近远期疗效及其影响因素

目的 探讨聚焦超声治疗外阴上皮内非瘤样病变的近远期疗效及并发症,并初步分析其预后影响因素。方法 选择经病理检查证实为外阴上皮内非瘤样病变患者共76例,采用聚焦超声进行治疗。术后定期随访局部瘙痒症状的改善情况,采用阴道镜检查方法观察体征的变化。结果 聚焦超声治疗后平均随访28．3个月（24～60个月）,有39例患者治愈（27例为鳞状上皮增生型,12例为硬化性苔癣型）,总治愈率为51％（39／76）,总有效率达95％（72／76）,累计复发率为36％（26／72）。对复发病例在间隔一段时间后进行再次聚焦超声治疗,同样可以获得显著的临床治疗效果,18例复发后再治疗患者中,6例完全恢复正常,12例症状明显减轻或缓解。76例患者中,4例（2例鳞状上皮增生型,2例硬化性苔癣型）于治疗后2～4h出现治疗区皮肤少量水疱,经抗炎、对症治疗后均痊愈。另有2例（1例鳞状上皮增生型,1例硬化性苔癣型）在治疗后2周出现治疗区局部皮肤浅表溃疡,经抗炎、对症及促表皮生长等治疗3周后痊愈。76例患者经24～60个月的临床观察未发现有远期并发症。不同的麻醉方式及不同的病理类型对聚焦超声治疗效果的影响比较,差异无统计学意义（P〉0．05）,但病程越短、年龄越小,聚焦超声治疗的临床效果越好。结论 聚焦超声用于治疗外阴上皮内非瘤样病变安全有效,无远期并发症发生。

Th17 cell‐derived miR‐155‐5p modulates interleukin‐17 and suppressor of cytokines signaling 1 expression during the progression of systemic sclerosis

Background miR‐155‐5p is associated with autoimmune diseases. T helper 17 (Th17) cells, interleukin (IL)‐17, and suppressor of cytokines signaling 1 (SOCS1) have important roles in the pathogenesis of systemic sclerosis (SSc). The purpose of this study was to explore the role of miR‐155‐5p in the regulation of IL‐17 and SOCS1 expression in Th17 cells and the subsequent effect on SSc disease progression.MethodsTh17 cells were isolated from peripheral blood mononuclear cells of SSc patients and healthy controls (HCs). RT‐qPCR and western blotting were used to examine the expression patterns of miR‐155‐5p, IL‐17, and SOCS1. Luciferase reporter assays were performed to confirm SOCS1 as a target of miR‐155‐5p. RNA pull‐down assays were performed to detect the interaction of IL‐17 and SOCS1 with miR‐155‐5p. In situ hybridization was performed to analyze the co‐expression pattern of miR‐155‐5p and IL17A in Th17 cells.ResultsThe levels of Th17 cell‐derived miR‐155‐5p were significantly up‐regulated in SSc patients compared with HCs, and its levels were negatively correlated with SOCS1 levels. Meanwhile, miR‐155‐5p positively regulated IL‐17 expression levels in Th17 cells isolated from SSc patients as the disease progressed. Using pmirGLO vectors, SOCS1 was confirmed as a target of miR‐155‐5p. The binding status of IL‐17 and SOCS1 to miR‐155‐5p was related to SSc progression. An increase in the co‐localization of miR‐155‐5p and IL‐17 was associated with greater SSc progression.ConclusionsIL‐17 and SOCS1 expression modulated by Th17 cell‐derived miR‐155‐5p are critical for SSc progression, which may provide novel insights into the pathogenesis of SSc.     

Comparative study on the gastrointestinal- and immune- regulation functions of Hedysari Radix Paeparata Cum Melle and Astragali Radix Praeparata cum Melle in rats with spleen-qi deficiency,based on fuzzy matter-element analysis

ContextHedysari Radix Praeparata Cum Melle (HRPCM) and Astragali Radix Praeparata Cum Melle (ARPCM) are used interchangeably in clinics to treat spleen-qi deficiency (SQD) symptom mainly including gastrointestinal dysfunction and decreased immunity, which has unknown differences in efficacy.ObjectiveTo investigate the differences between HRPCM and ARPCM on intervening gastrointestinal- and immune-function with SQD syndrome.Materials and methodsAfter the SQD model was established, the Sprague–Dawley (SD) rats were randomly divided into nine groups (n = 10): normal; model; Bu-Zhong-Yi-Qi Pills; 18.9, 12.6 and 6.3 g/kg dose groups of HRPCM and ARPCM. Gastrointestinal function including d-xylose, gastrin, amylase vasoactive intestinal peptide, motilin, pepsin, H⁺/K⁺-ATPase, Na⁺/K⁺-ATPase, sodium-glucose cotransporter 1 (SGLT1), glucose transporter 2 (GLUT2) and immune function including spleen and thymus index, blood routine, interleukin (IL)-2, IL-6, interferon-γ (IFN-γ), tumour necrosis factor-α (TNF-α), immunoglobulin (Ig) M, IgA, IgG and delayed-type hypersensitivity (DTH) were detected. Finally, the efficacy differences were analysed comprehensively by the fuzzy matter-element method.ResultsIn regulating immune, the doses differences in efficacy between HRPCM and ARPCM showed in the high-dose (18.9 g/kg), but there were no differences in the middle- and low- dose (12.6 and 6.3 g/kg); the efficacy differences were primarily reflected in levels of IL-6, IFN-γ, TNF-α and IgM in serum, and the mRNA expression of IL-6 and IFN-γ in the spleen. In regulating gastrointestinal, the efficacy differences were primarily reflected in the levels of D-xylose, MTL, and GAS in serum, and the mRNA and protein expression of SGLT1 and GLUT2 in jejunum and ileum.Discussion and conclusionsHRPCM is more effective than ARPCM on regulating gastrointestinal function and immune function with SQD syndrome. Therefore, we propose that HRPCM should be mainly used to treat SQD syndrome in the future.
