Background
Acute myocardial infarction (AMI) causes irreversible myocardial damage and release of inflammatory mediators, including cytokines, chemokines and miRNAs. We aimed to investigate changes in the levels of cytokines (IL-6, TNF-α and IL-10), miRNAs profiles (miR-146 and miR-155) and distribution of different monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) in the acute and post-healing phases of AMI.Methods
In eighteen consecutive AMI patients (mean age 56.78?±?12.4 years, mean left ventricle ejection fraction – LVEF: 41.9?±?9.8%), treated invasively, monocyte subsets frequencies were evaluated (flow cytometry), cytokine concentrations were analyzed (ELISA) as well as plasma miRNAs were isolated twice – on admission and after 19.2?±?5.9 weeks of follow-up. Measurements were also performed among healthy volunteers.Results
AMI patients presented significantly decreased frequencies of classical cells in comparison to healthy controls (median 71.22% [IQR: 64.4–79.04] vs. 84.35% [IQR: 81.2–86.7], p?=?0.001) and higher percent of both intermediate and non-classical cells, yet without statistical significance (median 6.54% [IQR: 5.14–16.64] vs. 5.87% [IQR: 4.48–8.6], p?=?0.37 and median 5.99% [IQR: 3.39–11.5] vs. 5.26% [IQR: 3.62–6.2], p?=?0.42, respectively). In AMI patients both, analyzed plasma miRNA concentrations were higher than in healthy subjects (miR-146: median 5.48 [IQR: 2.4–11.27] vs. 1.84 [IQR: 0.87–2.53], p?=?0.003; miR-155: median 25.35 [IQR: 8.17–43.15] vs. 8.4 [IQR: 0.08–16.9], p?=?0.027, respectively), and returned back to the values found in the control group in follow-up. miR-155/miR-146 ratio correlated with the frequencies of classical monocytes (r=0.6, p?=?0.01) and miR-155 correlated positively with the concentration of inflammatory cytokines ? IL-6 and TNF-α.Conclusions
These results may suggest cooperation of both pro-inflammatory and anti-inflammatory signals in AMI in order to promote appropriate healing of the infarcted myocardium. 相似文献32.

ObjectiveProgrammed death ligand 1 (PD-L1) has been reported to be connected to prognosis in individuals with malignant pleural mesothelioma (MPM), although there is no consensus based on data from previous studies. Accordingly, this quantitative meta-analysis investigated prognostic and clinicopathological utility of PD-L1 in patients with MPM.MethodsA comprehensive search of the PubMed, Web of Science, Embase, and Cochrane Library databases for articles published up to October 4, 2019 was performed. Studies using immunohistochemical techniques to detect/quantify the expression of PD-L1 in MPM tissue were enrolled in the analysis. The combined hazard ratio (HR) and corresponding 95% confidence interval (CI) was applied to assess the association between PD-L1 expression and overall survival (OS).ResultsA total of 11 studies comprising 1606 patients was included in the present meta-analysis. For OS, pooled data revealed an HR of 1.50 (95% CI 1.32–1.70; p < 0.001), suggesting that patients with PD-L1 overexpression experience inferior OS. Subgroup analysis revealed that elevated PD-L1 remained a significant prognostic indicator for worse OS, irrespective of sample size, cut-off value, ethnicity, and Newcastle-Ottawa Scale score. Moreover, PD-L1 overexpression was associated with non-epithelioid histology (odds ratio 4.30 [95% CI 1.89–9.74]; p < 0.001).ConclusionsResults of this meta-analysis show that elevated expression of PD-L1 could be a factor predicting poorer survival in patients with MPM. 相似文献

ObjectiveMethamphetamine is used extensively around the world as a psychostimulant. The complications related to methamphetamine include methamphetamine-induced neurotoxicity, mainly involving intraneuronal processes, such as oxidative stress and excitotoxicity. Curcumin is effective against neuronal injury due to its antioxidant, anti-inflammatory effects. In this study, we examined the protective effects of curcumin against methamphetamine neurotoxicity.MethodsSixty male Wistar rats were divided into the following groups: control (n = 12), DMSO (n = 12), methamphetamine (n = 12), and methamphetamine + curcumin (100 and 200 mg/kg, respectively, intraperitoneal [IP]; n = 12). Neurotoxicity was induced by 40 mg/kg of methamphetamine administrated through 4 injections (4 × 10 mg/kg, q2h, IP). Curcumin (100 and 200 mg/kg) was administered at 7 days after the last methamphetamine injection. By using a Morris water maze task, the hippocampus-dependent memory and spatial learning were evaluated 1 day after the last curcumin injection. Then, the animal brains were isolated for biochemical measurements, as well as glial fibrillary acidic protein (GFAP), ionized calcium-binding adaptor protein-1(Iba-1) and caspase-3 immunohistochemical staining.ResultsThe current study demonstrated that administration of curcumin significantly attenuates spatial memory impairment (P < 0.01) following methamphetamine neurotoxicity. Curcumin caused a significant increase in the levels of superoxide dismutase and glutathione peroxidase (P < 0.05). However, it decreased tumor necrosis factor (TNF-α) (P < 0.05) and malondialdehyde (P < 0.01) levels as compared to the methamphetamine group. Also, curcumin significantly reduced Iba-1 (P < 0. 01), GFAP and caspase-3 positive cells in the hippocampus (P < 0.001).ConclusionCurcumin exerted neuroprotective effects on methamphetamine neurotoxicity because of its antioxidant and anti-inflammatory effect. 相似文献

Pulmonary immune-related adverse events represent rare but potentially severe side effects of immunotherapies. Diagnosis is often challenging, as symptoms and imaging features are not specific and may mimic other lung diseases, thus potentially delaying appropriate patient management. In this setting, an accurate imaging evaluation is essential for a prompt detection and correct management of these drug-induced lung diseases. The purpose of this article is to review the different types of pulmonary immune-related adverse events, describe their imaging characteristics on both high-resolution computed tomography and positron emission tomography/computed tomography and stress their underlying diagnostic challenge by presenting the mimickers. 相似文献

重症心源性肺水肿伴休克患者的机械通气治疗 总被引:3,自引:0,他引:3
目的研究重症心源性肺水肿伴休克患者机械通气(MV)治疗时通气压力的选择对预后的影响。方法将符合标准的22例患者分为两组对照组9例,常规给予较低通气压力和加强药物治疗;治疗组13例,适当增加通气压力。观察血压、临床症状和动脉血气的变化。结果调整MV后30分钟时,治疗组收缩压迅速由(95±12)mmHg升至(130±15)mmHg(P<0.001),呼吸频率(RR)由(38±11)次/min降至(27±6)次/min(P<0.005),心率(HR)由(126±15)次/min降至(105±12)次/min(P<0.001);对照组上述指标变化不明显。2小时后治疗组的升压药用量减少(70±15)%,对照组则增加(20±5)%;同时在吸氧浓度不变的情况下,治疗组的PaO2由(81±12)mmHg升至(140±15)mmHg(P<0.001),明显高于对照组PaO2的改善。24~48小时内治疗组11例患者(85%)停用升压药,对照组2例(22%)停用。最终治疗组100%的患者好转出院,对照组为45%(P<0.05)。结论与低压力通气相比,适当增加MV通气压力不仅可迅速改善重症心源性水肺肿伴休克患者的低氧血症,也可迅速升高血压,改善心功能,降低病死率。 相似文献

冠心病合并其他器质性心脏病的外科治疗 总被引:1,自引:0,他引:1
目的分析冠心病合并其他器质性心脏病的临床特点,探讨一期外科治疗的方法和临床疗效。方法分析2004年4月至2006年4月冠心病合并其他器质性心脏病患者13例,其中风湿性心脏病联合瓣膜病1例,二尖瓣病变4例,二尖瓣退行性病变3例,主动脉瓣关闭不全3例,升主动脉瘤1例,继发孔房缺1例。因冠心病首诊入院5例,以其他器质性心脏病首诊入院8例。术前有心绞痛症状者8例,无心绞痛5例。体外循环下一期外科治疗。结果无死亡病例,13例均顺利出院。冠脉搭桥+瓣膜置换8例,冠脉搭桥+瓣膜成形3例,冠脉搭桥+Bentall+室壁瘤切除1例,冠脉搭桥+房缺修补1例。手术中搭桥1~3支,平均(1.92±0.73)支。术后1周,左心室舒张末内径(LVDD)为(51.77±2.64)mm,较术前[(58.92±3.81)mm]明显缩小(P<0.05)。随访3个月,心绞痛症状完全消失,心功能(NYHA)明显提高(P<0.05)。结论冠心病合并其他器质性心脏病临床症状无特异性,容易漏诊。虽然手术风险性和难度增加,但未得到血液重建,对患者更将是致命性的灾难,应争取一期手术。 相似文献

自体血预充技术对血液保护作用的研究 总被引:2,自引:1,他引:1
目的研究采用自体血预充技术对体外循环下心脏手术的血液保护作用。方法40例非急诊手术的首次接受体外循环下心脏冠脉搭桥的患者,依性别(男女比例)、年龄、体重、身高、体表面积(BSA)和射血分数(EF)进行配对后分为两组:自体血预充组(n=20)和经典预充组(n=20)。自体血预充组:用1250ml晶体液和8000IU肝素预充,体外循环开始前先采用自体血预充技术置换出大部分最初预充液,维持平均动脉压(MAP)在50mmHg以上。经典预充组:1250ml晶体液和8000IU肝素预充。心肌保护均采用Calafiore温血停跳液灌注。体外循环中保持温度35.0℃~35.5℃,流量2.5~2.8L·min-·1m-2。所有患者按标准手术步骤进行手术。手术结束前将体外循环系统中余血全部回输给患者。结果自体血预充组平均置换出(894±171)ml的最初预充液,患者体外循环中,手术结束时,术后6h、1d、2d的HCT水平均明显高于经典预充组(P<0.05)。自体血预充组围术期人均输血量明显低于经典预充组[(0.16±1.09)U/人和(0.97±2.18)U/人,P<0.05]。自体血预充组患者术后胸腔引流量较经典预充组明显减少(303±89ml和495±112ml,P<0.05)。结论自体血预充技术的应用能减少血液稀释,减少围术期输血量,保护血液。 相似文献
