    最近的研究表明,单核细胞淋巴细胞比率(MLR),中性粒细胞淋巴细胞比率(NLR),血小板淋巴细胞比率(PLR),C反应蛋白(CRP),和全身免疫炎症指数(SII)可作为老年髋部骨折患者术后早期死亡率的有价值的预测因子.该研究的主要目的是检查术前MLR,NLR,PLR,CRP,髋部骨折手术后老年患者的SII水平和3年死亡率风险。
    该研究包括在2018年11月至2019年11月期间接受髋部骨折手术的65岁或以上患者。MLR的入学水平,NLR,PLR,CRP,和SII被测量。中位随访期为3.1年。Cox比例风险模型用于计算死亡率的风险比(HR),并调整潜在的协变量。时间依赖性受试者工作特征(ROC)曲线用于评估炎症指标对死亡率的预测能力。
    共有760名患者完成了随访(79.4±7.8年,71.1%女性)。术前MLR较高与术后3年死亡风险增加显著相关(HR1.811,95%CI1.047-3.132,P=0.034)。然而,术前NLR,PLR,CRP,SII和3年死亡率。用于预测30天的MLR的ROC曲线下面积(AUC),120天,1年,3年死亡率为0.74(95%CI0.53-0.95),0.70(95%CI0.57-0.83),0.67(95%CI0.60-0.74),和0.61(95%CI0.56-0.66),分别。
    术前MLR是预测老年髋部骨折患者3年死亡率的一个有用的炎症指标,但是它的预测能力随着时间的推移而减弱。
    UNASSIGNED: Recent research indicates that the monocyte lymphocyte ratio (MLR), neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), C-reactive protein (CRP), and systemic immune-inflammation index (SII) may serve as valuable predictors of early postoperative mortality in elderly individuals with hip fractures. The primary objective of the study was to examine the association between preoperative MLR, NLR, PLR, CRP, and SII levels and 3-year mortality risk in geriatric patients after hip fracture surgery.
    UNASSIGNED: The study included patients aged 65 years or older who underwent hip fracture surgery between November 2018 and November 2019. Admission levels of MLR, NLR, PLR, CRP, and SII were measured. The median follow-up period was 3.1 years. Cox proportional hazards models were used to calculate the hazard ratio (HR) for mortality with adjusting for potential covariates. Time-dependent receiver operating characteristic (ROC) curves were employed to assess the predictive capability of inflammatory indicators for mortality.
    UNASSIGNED: A total of 760 patients completed the follow-up (79.4 ± 7.8 years, 71.1% female). A higher preoperative MLR was found to be significantly associated with an increased 3-year postoperative mortality risk (HR 1.811, 95% CI 1.047-3.132, P = 0.034). However, no significant correlations were observed between preoperative NLR, PLR, CRP, SII and 3-year mortality. The areas under the ROC curve (AUCs) of MLR for predicting 30-day, 120-day, 1-year, and 3-year mortality were 0.74 (95% CI 0.53-0.95), 0.70 (95% CI 0.57-0.83), 0.67 (95% CI 0.60-0.74), and 0.61 (95% CI 0.56-0.66), respectively.
    UNASSIGNED: Preoperative MLR is a useful inflammatory marker for predicting 3-year mortality in elderly hip fracture patients, but its predictive ability diminishes over time.

    乙酰胆碱酯酶(AChE)是治疗阿尔茨海默病的主要药物靶点之一。目前的这项研究依赖于多种分子建模方法来开发新的有效的AChE抑制剂。我们基于一组取代的5-苯基-1,3,4-恶二唑和N-苄基哌啶类似物,使用多元线性回归的统计方法探索了2DQSAR研究,它们是最近合成的,并证明了它们对乙酰胆碱酯酶(AChE)的抑制活性。分子描述符,极性表面积,偶极矩,和分子量是控制AChE抑制活性的关键结构特性。根据统计参数选择MLR模型:R2=0.701,R2检验=0.76,Q2CV=0.638,RMSE=0.336,证明了其预测可靠性。随机化试验,VIF测试,采用适用性领域试验验证了模型的稳健性。因此,设计了11种新分子,具有比模型分子更高的抗阿尔茨海默病活性。我们通过计算机模拟ADMET研究证明了它们改善的药代动力学特性。进行了分子对接研究以探索它们的AChE抑制机制和活性位点中的结合亲和力。化合物M1、M2和M6的结合评分为(-12.6kcal/mol),(-13千卡/摩尔),和(-12.4千卡/摩尔),分别,其高于标准抑制剂多奈哌齐,结合评分为(-10.8kcal/mol)。使用超过100ns的分子动力学模拟来验证分子对接结果,表明化合物M1和M2在活性位点保持稳定,证实了它们作为有前途的抗AChE抑制剂的潜力。
    Acetylcholinesterase (AChE) is one of the main drug targets for treating Alzheimer\'s disease. This current study relies on multiple molecular modeling approaches to develop new potent inhibitors of AChE. We explored a 2D QSAR study using the statistical method of multiple linear regression based on a set of substituted 5-phenyl-1,3,4-oxadiazole and N-benzylpiperidine analogs, which were recently synthesized and proved their inhibitory activities against acetylcholinesterase (AChE). The molecular descriptors, polar surface area, dipole moment, and molecular weight are the key structural properties governing AChE inhibition activity. The MLR model was selected based on its statistical parameters: R2 = 0.701, R2test = 0.76, Q2CV = 0.638, and RMSE = 0.336, demonstrating its predictive reliability. Randomization tests, VIF tests, and applicability domain tests were adopted to verify the model\'s robustness. As a result, 11 new molecules were designed with higher anti-Alzheimer\'s activities than the model molecule. We demonstrated their improved pharmacokinetic properties through an in silico ADMET study. A molecular docking study was conducted to explore their AChE inhibition mechanisms and binding affinities in the active site. The binding scores of compounds M1, M2, and M6 were (-12.6 kcal/mol), (-13 kcal/mol), and (-12.4 kcal/mol), respectively, which are higher than the standard inhibitor Donepezil with a binding score of (-10.8 kcal/mol). Molecular dynamics simulations over 100 ns were used to validate the molecular docking results, indicating that compounds M1 and M2 remain stable in the active site, confirming their potential as promising anti-AChE inhibitors.

    中国提倡分级管理,以有效管理慢性阻塞性肺疾病(COPD)患者,降低COPD急性加重(AE-COPD)的发生率和死亡率。然而,基层医院和社区医院通常无法获得先进的设备和技术。全血细胞计数(CBC),通常在这些医院中使用,提供了具有成本效益和易于访问的优势。本研究旨在评估血常规指标在辅助诊断AE-COPD中的意义。
    在这项研究中,我们共纳入112例诊断为AE-COPD的患者,92例稳定期COPD患者,和一个由60名健康个体组成的对照组。临床特征,CBC参数,并在2小时内收集血清CRP水平。采用Spearman相关检验评价NLR/PLR/MLR与CRP的相关性。NLR的诊断准确性,使用受试者工作特征曲线(ROC)和曲线下面积(AUC)评估AE-COPD中的PLR和MLR。对NLR指标进行二元Logistic回归分析,PLR和MLR。
    我们发现AE-COPD患者的NLR水平明显较高,PLR和MLR与稳定期COPD患者形成对比。此外,研究显示CRP与NLR之间存在显著的相关性(rs=0.5319,P<0.001),PLR(rs=0.4424,P<0.001),和MLR(rs=0.4628,P<0.001)。通过利用特定的截止值,NLR的合并,PLR和MLR增强了诊断灵敏度。二元logistic回归分析显示NLR和MLR升高是AE-COPD进展的危险因素。
    随着NLR水平的提高,PLR和MLR可以作为生物标志物,类似于CRP,用于COPD患者急性加重的诊断和评估。需要进一步的研究来验证这一概念。
    UNASSIGNED: Hierarchical management is advocated in China to effectively manage chronic obstructive pulmonary disease (COPD) patients and reduce the incidence and mortality of acute exacerbation of COPD (AE-COPD). However, primary and community hospitals often have limited access to advanced equipment and technology. Complete blood count (CBC), which is commonly used in these hospitals, offers the advantages of being cost-effective and easily accessible. This study aims to evaluate the significance of routine blood indicators in aiding of diagnosing AE-COPD.
    UNASSIGNED: In this research, we enrolled a total of 112 patients diagnosed with AE-COPD, 92 patients with stable COPD, and a control group comprising 60 healthy individuals. Clinical characteristics, CBC parameters, and serum CRP levels were collected within two hours. To assess the associations between NLR/PLR/MLR and CRP by Spearman correlation test. The diagnostic accuracy of NLR, PLR and MLR in AE-COPD was assessed using Receiver Operating Characteristic Curve (ROC) and the area under the curve (AUC). Binary Logistic Regression analysis was conducted for the indicators of NLR, PLR and MLR.
    UNASSIGNED: We found that patients with AE-COPD had significantly higher levels of NLR, PLR and MLR in contrast to patients with stable COPD. Additionally, the study revealed a noteworthy correlation between CRP and NLR (rs=0.5319, P<0.001), PLR (rs=0.4424, P<0.001), and MLR (rs=0.4628, P<0.001). By utilizing specific cut-off values, the amalgamation of NLR, PLR and MLR augmented diagnostic sensitivity. Binary logistic regression analysis demonstrated that heightened NLR and MLR act as risk factors for the progression of AE-COPD.
    UNASSIGNED: The increasing levels of NLR, PLR and MLR could function as biomarkers, akin to CRP, for diagnosis and assessment of acute exacerbations among COPD patients. Further research is required to validate this concept.

    背景:蛛网膜下腔出血是一种毁灭性疾病。即使经过最先进的治疗,患者也会出现并发症,包括脑血管痉挛(CVS),迟发性脑缺血(DCI),动脉瘤性蛛网膜下腔出血(aSAH)后的慢性脑积水(CH)。我们研究的目的是确定C反应蛋白与淋巴细胞比率(CLR)对aSAH后神经功能结局和并发症的预测价值。方法:我们回顾性分析了166例符合纳入标准的aSAH患者。采用多因素logistic回归分析评价独立危险因素。通过计算受试者工作特征(ROC)曲线下的面积,比较了不同模型的预测值。结果:不良预后患者的CLR入院水平(6个月mRS3-6),CVS,DCI和CH明显高于预后良好的患者(6个月mRS0-2),非CVS,非DCI和非CH。多因素logistic回归分析显示,入院时CLR与CVS独立相关(OR[95%CI]2.116[1.507-2.971];p<0.001),和DCI(OR[95%CI]1.594[1.220-2.084];p=0.001)。在ROC分析中,不良结局(6个月mRS3-6)的CLR曲线下面积(AUC),CVS,DCI和CH预测为(AUC[95%CI]0.639[0.555-0.724];p=0.002),(AUC[95%CI]0.834[0.767-0.901];p<0.001),(AUC[95%CI]0.679[0.581-0.777];p<0.001),和(AUC[95%CI]0.628[0.343-0.713];p=0.005)显示入院CLR对aSAH后CVS具有良好的预测价值。入院CLR预测CVS的敏感性和特异性分别为77.1%和75.4%。入院时CLR为0.757mg×10-6被确定为区分CVS和非CVS的最佳截止阈值(CVS:CLR<0.757mg×10-611/100[11.0%]与CLR≥0.757mg×10-637/66[56.1%];p<0.001)。结论:入院时高水平的CLR是aSAH后CVS和DCI的独立危险因素。入院CLR是一个易于量化的实验室参数,可以有效地预测aSAH后的CVS,这可以为临床医生评估aSAH患者的可能进展和治疗策略提供一些指导。
    Background: Subarachnoid hemorrhage is a devastating disease. Even after state-of-the-art treatment patients suffer from complications, including cerebral vasospasm (CVS), delayed cerebral ischemia (DCI), and chronic hydrocephalus (CH) following aneurysmal subarachnoid hemorrhage (aSAH). The aim of our study is to identify the predictive value of the C-reactive protein to lymphocyte ratio (CLR) for neurological functional outcome and complications after aSAH. Methods: We retrospectively analyzed a total of 166 aSAH patients who met the inclusion criteria enrolled in our study. Multivariate logistic regression analyses were performed to evaluate the independent risk factors. The predictive value of different models was compared by calculating the areas under the receiver operating characteristic (ROC) curve. Results: On-admission levels of CLR in patients with poor outcomes (6 months mRS 3-6), CVS, DCI, and CH were significantly higher than those in patients with good outcomes (6 months mRS 0-2), non-CVS, non-DCI, and non-CH. Multivariate logistic regression analysis revealed that admission CLR was independently associated with CVS (OR [95% CI] 2.116 [1.507-2.971]; p < 0.001), and DCI (OR [95% CI] 1.594 [1.220-2.084]; p = 0.001). In ROC analysis, the area under the curve (AUC) of CLR for poor outcomes (6 months mRS 3-6), CVS, DCI, and CH prediction were (AUC [95% CI] 0.639 [0.555-0.724]; p = 0.002), (AUC [95% CI] 0.834 [0.767-0.901]; p < 0.001), (AUC [95% CI] 0.679 [0.581-0.777]; p < 0.001), and (AUC [95% CI] 0.628 [0.543-0.713]; p = 0.005) revealing that admission CLR had a favorable predictive value for CVS after aSAH. The sensitivity and specificity of admission CLR for CVS prediction were 77.1% and 75.4%. On-admission CLR of 0.757 mg × 10-6 was identified as the best cutoff threshold to discriminate between CVS and non-CVS (CVS: CLR < 0.757 mg × 10-6 11/100 [11.0%] vs. CLR ≥ 0.757 mg × 10-6 37/66 [56.1%]; p < 0.001). Conclusions: High levels of on-admission CLR serve as an independent risk factor for CVS and DCI after aSAH. Admission CLR is an easy-to-quantify laboratory parameter that efficiently predicts the CVS after aSAH, which can provide some guidance for clinicians to evaluate for possible progression and treatment strategies in patients with aSAH.

    背景:中性粒细胞与淋巴细胞比率(NLR),淋巴细胞与单核细胞比率(LMR),和托盘淋巴细胞比率(PLR)目前被验证为廉价和可获得的生物标志物在不同类型的实体瘤,包括头颈癌(HNC)。
    目的:为了评估NLR的可能目的和生物标志物价值,PLR,和MLR记录HNC的治疗前(放疗/化疗)。
    方法:来自Craiova县急诊医院肿瘤科门诊(2002年1月至2022年12月)的肿瘤记录中纳入的190例HNC患者,39例符合纳入标准(鳞状细胞癌和计算治疗前(化疗/放疗)NLR值的可能性,PLR,还有MLR.总生存期(OS)值与NLR相关,PLR,还有MLR.
    结果:NLR的中值,PLR,MLR为6.15(1.24-69),200.79(61.3-1775.0),和0.53(0.12-5.5),分别。在研究中,NLR的平均值,PLR,和MLR分别为2.88、142.97和0.36,已获得。研究组的中位OS为11个月(1-120)。尽管存在Pearson的负相关,变量之间的关系很弱,值R=0.07,p=0.67,R=0.02,p=0.31和R=0.07,p=0.62与NLR相关,PLR,还有MLR,分别,与OS相关。NLR的中值,PLR,对于治疗前NLR值<2的HNC病例和NLR值≥6的HNC病例(分别为23.5、232.78和0.79),计算MLR(分别为1.53、90.32和0.18).NLR<2和NLR≥6的病例的中位OS分别为17.4个月和13个月,分别。
    结论:数据的比较分析突出了NLR值低的情况对OS的益处。不仅在HNSCC中作为预后标志物的临界NLR值(在2和6之间)的作用,而且在预后评分中包括PLR和MLR也必须在将来定义。选择更统一的纳入标准的前瞻性研究可以证明治疗前NLR的价值,PLR,和MLR通过加强或降低HNSCC的非手术治疗来进行治疗分层。
    BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and pallets-to-lymphocyte ratio (PLR) are currently validated as cheap and accessible biomarkers in different types of solid tumors, including head and neck cancers (HNC).
    OBJECTIVE: To evaluate the possible purposes and biomarker value of NLR, PLR, and MLR recorded pre-treatment (radiotherapy/chemotherapy) in HNC.
    METHODS: From 190 patients with HNC included in the oncology records in the oncology outpatient clinic of the Craiova County Emergency Hospital (from January 2002 to December 2022), 39 cases met the inclusion criteria (squamous cell carcinoma and the possibility to calculate the pre-treatment (chemotherapy/radiotherapy) value of NLR, PLR, and MLR. Overall survival (OS) values were correlated with NLR, PLR, and MLR.
    RESULTS: The median values for NLR, PLR, and MLR were 6.15 (1.24-69), 200.79 (61.3-1775.0), and 0.53 (0.12-5.5), respectively. In the study, the mean values for NLR, PLR, and MLR of 2.88, 142.97, and 0.36, respectively, were obtained. The median OS in the study group was 11 months (1-120). Although a negative Pearson\'s correlation was present, the relationship between the variables was only weak, with values of R = 0.07, p = 0.67, R = 0.02, p = 0.31, and R = 0.07, p = 0.62 being related to NLR, PLR, and MLR, respectively, in correlation with OS. The median values of NLR, PLR, and MLR were calculated (1.53, 90.32, and 0.18, respectively) for the HNC cases with pre-treatment values of NLR < 2 and for the HNC cases with NLR values ≥ 6 (23.5, 232.78, and 0.79, respectively). The median OS for cases with NLR < 2 and NLR ≥ 6 were 17.4 and 13 months, respectively.
    CONCLUSIONS: The comparative analysis of the data highlights a benefit to OS for cases low values of NLR. The role of not only borderline NLR values (between 2 and 6) as a prognostic marker in HNSCC but also the inclusion of PLR and MLR in a prognostic score must also be defined in the future. Prospective studies with more uniformly selected inclusion criteria could demonstrate the value of pre-treatment NLR, PLR, and MLR for treatment stratification through the intensification or de-escalation of non-surgical curative treatment in HNSCC.

    脊髓性肌萎缩是一种遗传性神经肌肉疾病,可导致肌肉无力和萎缩,其特征是脊髓前角细胞中α运动神经元的丢失。该疾病的出现是由于运动神经元存活蛋白水平低。脊髓性肌萎缩症的治疗正在进行临床试验。基于喹唑啉的化合物是有希望的,因为它们在源自患者的成纤维细胞上进行了测试,并且发现它们增加存活运动神经元蛋白水平。在这项研究中,使用多元线性回归,我们使用2,4-二氨基喹唑啉衍生物的实验性存活运动神经元-2启动子活性值,生成了稳健有效的定量结构-活性关系模型来预测新候选化合物的存活运动神经元-2启动子活性。预测通过将已知药物Risdiplam的吡啶并[1,2-α]嘧啶-4-酮部分与2,4-二氨基喹唑啉支架结合而设计的新型化合物表现出强的启动子活性。
    Spinal Muscular Atrophy is a genetic neuromuscular disease that leads to muscle weakness and atrophy and it is characterized by the loss of α-motor neurons in the spinal cord\'s anterior horn cells. The disease appears due to low levels of the survival motor neuron protein. There are continuing clinical trials for the treatment of Spinal Muscular Atrophy. Quinazoline-based compounds are promising since they were tested on fibroblasts derived from the patients and found to increase the survival motor neuron protein levels. In this study, using multiple linear regression, we generated robust and valid quantitative structure- activity relationship models to predict the survival motor neuron-2 promoter activity of the new candidate compounds using the experimental survival motor neuron-2 promoter activity values of 2,4-diaminoquinazoline derivatives taken from the literature. The novel compounds designed by combining the pyrido[1,2-α]pyrimidin-4-one moeity of the known drug Risdiplam with that of 2,4 - diaminoquinazoline scaffold were predicted to exhibit strong promoter activities.

    BACKGROUND: We aimed to investigate the relationship between monocyte/lymphocyte ratio (MLR) and monocyte/high-density lipoprotein ratio (MHR) with abdominal aortic calcification (AAC) in patients on peritoneal dialysis (PD).
    METHODS: The time-averaged (TA) of relevant indexes and AAC scores (AACs) of 160 eligible patients were measured.
    RESULTS: Patients divided into the new AAC (n = 57) and the other without (n = 82). High TA-MLR (OR = 110.537, p = 0.018) and long duration of dialysis (OR = 1.045, p < 0.001) were independent risk factors of the new AAC. Patients divided into the no AAC (n = 82), the moderate-to-severe AAC (n = 26), and the mild AAC (n = 52). High TA-MLR (OR = 42.649, p = 0.032), high age at starting PD (OR = 1.055, p < 0.001), and long duration of PD (OR = 1.036, p < 0.001) were independent risk factors of AAC severity.
    CONCLUSIONS: MLR is an independent risk factor for the occurrence and severity of AAC and its value for the assessment of AAC is better than MHR.

    Objective: To explore the influence factors of poor prognosis of esophageal squamous cell carcinoma (ESCC) and the predictive value of inflammatory reaction indexes including neutrophils and lymphocytes ratio (NLR), platelet and lymphocyte ratio (PLR), monocyte and lymphocyte ratio (MLR) provision and differentiation degree, infiltration depth, lymph node metastasis number on the postoperative recurrence of ESCC. Methods: A total of 130 patients with ESCC who underwent radical resection from February 2017 to February 2019 in Nanyang Central Hospital were selected and divided into good prognosis group (66 cases) and poor prognosis group (64 cases) according to the prognostic effect. The clinical data and follow-up data were collected. Multivariate logistic regression analysis was used to determine the independent influencing factors of poor prognosis. Spearman correlation analysis was used to determine the correlation between preoperative NLR, PLR and MLR with the degree of differentiation, depth of invasion and number of lymph node metastases. Receiver operating characteristic (ROC) curve analysis was used to evaluate the efficacy of NLR, PLR and MLR in predicting poor prognosis of ESCC. Results: Univariate analysis showed that the degree of differentiation, the degree of invasion and the number of lymph node metastasis were related to the prognoses of patients with ESCC (P<0.05). Multivariate logistic regression analysis showed that the degree of differentiation, depth of invasion and number of lymph node metastases were independent influencing factors for poor prognosis of patients with ESCC, moderate differentiation (OR=2.603, 95% CI: 1.009-6.715) or low differentiation (OR=9.909, 95% CI: 3.097-31.706), infiltrating into fibrous membrane (OR=14.331, 95% CI: 1.333-154.104) or surrounding tissue (OR=23.368, 95% CI: 1.466-372.578), the number of lymph node metastases ≥ 3 (OR=9.225, 95% CI: 1.693-50.263) indicated poor prognosis. Spearman correlation analysis showed that NLR was negatively correlated with the degree of differentiation and the number of lymph node metastases (r=-0.281, P=0.001; r=-0.257, P=0.003), PLR was negatively correlated with the degree of differentiation, depth of invasion and number of lymph node metastasis (r=-0.250, P=0.004; r=0.197, P=0.025; r=-0.194, P=0.027), MLR was positively correlated with the degree of differentiation and the number of lymph node metastasis (r=0.248, P=0.004; r=0.196, P=0.025). ROC curve analysis showed that the areas under the curve of NLR, PLR and MLR in predicting poor prognosis of ESCC were 0.971, 0.925 and 0.834, respectively. The best cut-off value of NLR was 2.87. The sensitivity and specificity of NLR in predicting poor prognosis of ESCC were 90.6% and 87.9%, respectively. The optimal cut-off value of PLR was 141.75. The sensitivity and specificity for predicting poor prognosis of ESCC were 92.2% and 87.9%, respectively. The best cut-off value of MLR was 0.40. The sensitivity and specificity of MLR in predicting poor prognosis of esophageal squamous cell carcinoma were 54.7% and 100.0%, respectively. Conclusions: The degree of differentiation, the degree of invasion and the number of lymph node metastases are closely related to the poor prognosis of patients with esophageal squamous cell carcinoma. NLR, PLR and MLR can provide important information for predicting the poor prognosis of esophageal squamous cell carcinoma.
    目的: 探讨食管鳞状细胞癌预后不良的影响因素及中性粒细胞与淋巴细胞比值(NLR)、血小板与淋巴细胞比值(PLR)、单核细胞与淋巴细胞比值(MLR)与分化程度、浸润深度、淋巴结转移数目等炎性反应指标对食管鳞状细胞癌术后复发的预测价值。 方法: 选取2017年2月至2019年2月在南阳市中心医院行根治术治疗的130例食管鳞状细胞癌患者,按照预后效果分为预后良好组(66例)和预后不良组(64例)。收集其临床资料和随访资料。采用多因素logistic回归分析确定患者预后不良的独立影响因素,采用Spearman相关分析明确术前NLR、PLR和MLR与分化程度、浸润深度、淋巴结转移数目的相关性,采用受试者工作特征(ROC)曲线分析评价NLR、PLR和MLR预测食管鳞状细胞癌预后不良的效能。 结果: 单因素分析显示,分化程度、浸润程度、淋巴结转移数目与食管鳞状细胞癌患者的预后有关(均P<0.05)。多因素logistic回归分析显示,分化程度、浸润深度和淋巴结转移数目均为食管鳞状细胞癌患者预后不良的独立影响因素,中分化(OR=2.603,95% CI:1.009~6.715)或低分化(OR=9.909,95% CI:3.097~31.706)、浸润到纤维膜(OR=14.331,95% CI:1.333~154.104)或周围组织(OR=23.368,95% CI:1.466~372.578)、淋巴结转移数目≥3枚(OR=9.225,95% CI:1.693~50.263)的患者患者预后不良。Spearman相关分析显示,NLR与分化程度、淋巴结转移数目呈负相关(r=-0.281,P=0.001;r=-0.257,P=0.003),PLR与分化程度、浸润深度、淋巴结转移数目呈负相关(r=-0.250,P=0.004;r=-0.197,P=0.025;r=-0.194,P=0.027),MLR与分化程度、淋巴结转移数目呈正相关(r=0.248,P=0.004;r=0.196,P=0.025)。ROC曲线分析显示,NLR、PLR和MLR预测食管鳞状细胞癌预后不良的曲线下面积分别为0.971、0.925和0.834。NLR的最佳界值为2.87,预测食管鳞状细胞癌预后不良的灵敏度为90.6%,特异度为87.9%。PLR的最佳界值为141.75,预测食管鳞状细胞癌预后不良的灵敏度为92.2%,特异度为87.9%。MLR的最佳界值为0.40,预测食管鳞状细胞癌预后不良的灵敏度为54.7%,特异度为100.0%。 结论: 分化程度、浸润程度、淋巴结转移数目与食管鳞状细胞癌预后不良密切相关,NLR、PLR和MLR能为食管鳞状细胞癌预后不良预测提供重要信息。.

    在这项研究中,我们研究了PFAS(全氟烷基和多氟烷基物质)与核激素受体(NHRs)的结合效力:过氧化物酶体增殖物激活受体(PPARs)α,β,以及γ和甲状腺激素受体(TRs)α和β。我们已经模拟了43种全氟烷基化合物的对接分数,并基于这些数据开发了QSAR(定量结构-活性关系)模型,用于预测与五种受体的结合概率。下一步,我们实施了开发的QSAR模型,用于筛选来自NORMAN数据库的一大组化合物(4464).计算机模拟分析表明,PFAS与受体结合的概率取决于链长,氟原子的数量,以及分子中分支的数量。根据调查结果,考虑的PFAS基团与PPARα结合,β,和γ只有低或中等概率,而在TRα和β的情况下,它是相似的,只是那些具有较长链的化学物质显示出中等高的结合概率。
    In this study, we investigated PFAS (per- and polyfluoroalkyl substances) binding potencies to nuclear hormone receptors (NHRs): peroxisome proliferator-activated receptors (PPARs) α, β, and γ and thyroid hormone receptors (TRs) α and β. We have simulated the docking scores of 43 perfluoroalkyl compounds and based on these data developed QSAR (Quantitative Structure-Activity Relationship) models for predicting the binding probability to five receptors. In the next step, we implemented the developed QSAR models for the screening approach of a large group of compounds (4464) from the NORMAN Database. The in silico analyses indicated that the probability of PFAS binding to the receptors depends on the chain length, the number of fluorine atoms, and the number of branches in the molecule. According to the findings, the considered PFAS group bind to the PPARα, β, and γ only with low or moderate probability, while in the case of TR α and β it is similar except that those chemicals with longer chains show a moderately high probability of binding.

    背景:新数据表明,与性别相关的免疫系统组成会影响癌症患者(pts)的免疫反应和免疫疗法的功效。本研究旨在探讨MLR在转移性结直肠癌(mCRC)患者中与性别相关的预后作用。
    方法:我们分析了2009年至2018年在Aviano和Pordenone(训练集)和Udine(验证集)肿瘤科治疗的490名mCRC患者的回顾性连续队列。意大利。使用单变量和多变量Cox回归模型评估MLR对总生存期(OS)的预后影响。通过ROC分析确定预测存活的最佳临界值。
    结果:总体而言,我们确定了288名男性(59%)和202名女性(41%);161名患者(33%)患有右侧,202(42%)左侧主色,和122(25%)直肠肿瘤。有趣的是,性别与MLR(p=0.004)和侧方(p=0.006)相关.获得的女性和男性MLR的截止值分别为0.27和0.49。根据对训练集的单变量分析,MLR(HR9.07,p≤0.001),女性MLR>0.27(HR1.95,p=0.003),男性MLR>0.49(HR2.65,p=0.010)与较差的OS相关,这也在验证集中得到证实。在多变量分析中,女性MLR>0.27(HR2.77,p=0.002),男性MLR&gt;0.49(HR5.39,p≤0.001),BRAF突变(HR3.38,p≤0.001),腹膜转移(HR2.50,p=0.003)仍然与OS恶化独立相关。
    结论:雄性和雌性具有不同的免疫应答。我们的研究表明,高MLR,无论是男性还是女性,是一个不利的独立预后因素。需要进一步的前瞻性研究来证实这些数据。
    Background: Emerging data suggest that gender-related immune system composition affects both immune response and efficacy of immunotherapy in cancer patients (pts). This study aimed to investigate the sex-related prognostic role of MLR in metastatic colorectal cancer (mCRC) pts. Methods: We analyzed a retrospective consecutive cohort of 490 mCRC patients treated from 2009 to 2018 at the Oncology Departments of Aviano and Pordenone (training set) and Udine (validation set), Italy. The prognostic impact of MLR on overall survival (OS) was evaluated with uni- and multivariable Cox regression models. The best cut-off value to predict survival was defined through ROC analyses. Results: Overall, we identified 288 males (59%) and 202 females (41%); 161 patients (33%) had a right-sided, 202 (42%) a left-sided primary, and 122 (25%) a rectal tumor. Interestingly, gender was associated with MLR (p = 0.004) and sidedness (p = 0.006). The obtained cut-off value for MLR in females and males was 0.27 and 0.49, respectively. According to univariate analysis of the training set, MLR (HR 9.07, p ≤ 0.001), MLR > 0.27 in females (HR 1.95, p = 0.003), and MLR > 0.49 in males (HR 2.65, p = 0.010) were associated with poorer OS, which was also confirmed in the validation set. In multivariate analysis, MLR > 0.27 in females (HR 2.77, p = 0.002), MLR > 0.49 in males (HR 5.39, p ≤ 0.001), BRAF mutation (HR 3.38, p ≤ 0.001), and peritoneal metastases (HR 2.50, p = 0.003) were still independently associated with worse OS. Conclusions: Males and females have a different immune response. Our study showed that high MLR, both in males and females, is an unfavorable Independent prognostic factor. Further prospective studies are needed to confirm these data.
