    Cenchrusfugigitalinus是一个新物种,主要用作饲料和蘑菇基质。然而,由于当地的农业用地政策,它通常不能种植在农田上。每年(短期)与其他作物套种Cenchrusfuggitrainus是促进中国南方草业可持续发展的创新策略。为了进一步调查,C.真菌单种植(MC),进行了枯萎病菌-马铃薯套种(CIP)和枯萎病菌-蚕豆套种(CIB)。与MC相比,土壤微生物生物量碳(SMBC),土壤有机质(SOM),氨态氮(AMN),pH和土壤氨基糖对CIP和CIB的根际土壤有积极影响,以及增强土壤固氮酶,亚硝酸还原酶,和过氧化物酶活性(p<0.05)。此外,CIP进步了根系活气(2.08倍)和粗卵白(1.11倍)。此外,CIB增强了枯草杆菌幼苗的粗纤维。这两种套种模式也改善了微生物组成和多样性(放线菌,Firmicutes,和拟杆菌,等。)在枯草杆菌幼苗的根际土壤中。在所有样本中,189个和59个基因参与甲烷循环和氮循环,分别,改善了丝氨酸循环的存在,单磷酸核酮糖,同化硝酸盐还原,甲烷吸收,和谷氨酸合成并抑制反硝化。通过相关性分析和Mantel检验,推定的功能基因,氮和甲烷循环中的编码功能,被证明对pH有显著的积极影响,水分,AMN,SOM,SMBC,和土壤过氧化物酶活性,而对土壤固氮酶活性和总氨基糖没有显着影响(p<0.05)。套种模式的短期影响被证明可以提高土地利用效率和单位土地面积的经济盈利能力,这些模式可以为乡村振兴提供可持续的农业生产。
    Cenchrus fungigraminus is a new species and is largely used as forage and mushroom substrate. However, it can usually not be planted on farmland on account of local agricultural land policy. Interplanting Cenchrus fungigraminus with other crops annually (short-term) is an innovative strategy to promote the sustainable development of the grass industry in southern China. To further investigate this, C. fungigraminus mono-planting (MC), C. fungigraminus-potato interplanting (CIP) and C. fungigraminus-broad bean interplanting (CIB) were performed. Compared to MC, soil microbial biomass carbon (SMBC), soil organic matter (SOM), ammoniacal nitrogen (AMN), pH and soil amino sugars had a positive effect on the rhizosphere soil of CIP and CIB, as well as enhancing soil nitrogenase, nitrite reductase, and peroxidase activities (p < 0.05). Moreover, CIP improved the root vitality (2.08 times) and crude protein (1.11 times). In addition, CIB enhanced the crude fiber of C. fungigraminus seedlings. These two interplanting models also improved the microbial composition and diversity (Actinobacteria, Firmicutes, and Bacteroidota, etc.) in the rhizosphere soil of C. fungigraminus seedlings. Among all the samples, 189 and 59 genes were involved in methane cycling and nitrogen cycling, respectively, which improved the presence of the serine cycle, ribulose monophosphate, assimilatory nitrate reduction, methane absorption, and glutamate synthesis and inhibited denitrification. Through correlation analysis and the Mantel test, the putative functional genes, encoding functions in both nitrogen and methane cycling, were shown to have a significant positive effect on pH, moisture, AMN, SOM, SMBC, and soil peroxidase activity, while not displaying a significant effect on soil nitrogenase activity and total amino sugar (p < 0.05). The short-term influence of the interplanting model was shown to improve land use efficiency and economic profitability per unit land area, and the models could provide sustainable agricultural production for rural revitalization.

    传统塑料作为海洋塑料垃圾广泛存在于海洋中。这项原位研究调查了七种常见常规塑料(PET,PVC,PS,EPS,PP,HDPE,和LDPE)在40天的时间内处于自然海洋环境中。所有塑料都显示出显著的化学变化和振荡的塑料氧化水平,表明氧化和去除氧化产物的协同过程。聚苯乙烯和具有杂原子的聚合物显示出最大的降解潜力,而纯聚烯烃表现出最高的碎裂风险。SEM图像表明EPS和纯聚烯烃在产生微塑料碎片方面的潜力,和具有杂原子的聚合物产生纳米塑料碎片。PS没有表现出任何表面降解迹象,可能是由于通过氧化增强的结晶度。研究结果强调需要减少EPS和纯聚烯烃的使用,这些聚烯烃通常用作一次性餐具和食品包装,并优先清理这些聚合物,以减少环境中的微塑料污染。
    Conventional plastics are widely present in the ocean as marine plastic debris. This in-situ study investigates the degradability and fragmentation of seven common conventional plastics (PET, PVC, PS, EPS, PP, HDPE, and LDPE) in natural marine environments over a 40-day period. All plastics showed significant chemical changes and oscillating plastic oxidation levels, indicating the synergistic processes of oxidation and removal of oxidation products. Polystyrenes and polymers with heteroatoms showed the largest degradation potentials, while pure polyolefins exhibited the highest fragmentation risks. SEM images suggest potentials of EPS and pure polyolefins in generating microplastic fragments, and polymers with heteroatoms in generating nanoplastic fragments. PS did not exhibit any surface degradation signs, potentially due to enhanced crystallinity through oxidation. The findings highlight the need for reduced usage of EPS and pure polyolefins which are commonly applied as disposable utensils and food packaging, and prioritized cleanup of these polymers to reduce microplastic pollution in the environment.

    本研究的目的是确定奥昔布宁的剂量与脊髓损伤(SCI)继发神经源性膀胱(NGB)患者逼尿肌压力降低之间的关系。在1999年1月至2016年12月期间接受泌尿外科评估的所有NGB和SCI患者的医院数据进行了检查。患者特征,在治疗前和治疗后收集尿动力学和膀胱管理细节.用于评估奥昔布宁治疗的主要结果是逼尿肌压(Pdet)的变化。使用协方差分析(ANCOVA)来研究奥昔布宁的剂量与Pdet减少之间的关系。总共包括245名参与者(112名没有接受药物治疗,133名接受奥昔布宁治疗)。在控制了混杂因素后,奥昔布宁每增加1mg,Pdet中平均减少0.9cmH2O(95%CI,-1.4~-0.3).通过留置导尿管对膀胱进行分层管理,奥昔布宁1mg与留置导尿管患者的Pdet平均下降0.5cmH2O(95%CI,-1.4~0.4)相关,清洁间歇导尿管和平衡膀胱患者的Pdet平均下降1.0cmH2O(95%CI,-1.7~-0.3)相关.这项研究为设定与SCI患者NGB反应变异性相关的药物起始剂量提供了指导。奥昔布宁被认为对SCI患者的NGB管理是临床有效的。
    The aim of the present study was to determine the relationship between dose of oxybutynin and reduction in detrusor pressure in individuals with neurogenic bladder (NGB) secondary to spinal cord injury (SCI). The hospital-based data were examined for all individuals with NGB and SCI who were admitted for urological evaluation between January 1999 and December 2016. Patient characteristics, urodynamics and bladder management details were collected at pre-treatment and post-treatment. The primary outcome used to assess oxybutynin treatment was the change in detrusor pressure (Pdet). Analysis of covariance (ANCOVA) was used to investigate the relationship between dosage of oxybutynin and decrease in Pdet. A total of 245 participants (112 who received no medication and 133 treated with oxybutynin) were included. After controlling for confounding factors, each 1 mg increase in oxybutynin was associated with a mean decrease of 0.9 cmH2O in Pdet (95% CI, -1.4 to -0.3). Stratifying bladder management by indwelling catheter, oxybutynin at a dose of 1 mg was associated with a mean decrease in Pdet of 0.5 cmH2O (95% CI, -1.4 to 0.4) in patients with indwelling catheters and 1.0 cmH2O (95% CI, -1.7 to -0.3) in patients with clean intermittent catheterization and balanced bladder. This study provided guidance for setting the starting dose of drugs associated with response variability in NGB with SCI. Oxybutynin is deemed to be clinically effective for managing NGB in patients with SCI.

    目的:急性肺栓塞(PE)是一种潜在的危及生命的疾病,其特征是肺动脉突然阻塞。尽管MAGGIC风险评分已成为预测慢性心力衰竭患者预后的有价值的工具,它也已被证明并确定为心力衰竭以外的各种心脏疾病的预后模型.在这项研究中,我们旨在探讨MAGGIC评分与PE患者不良结局之间的关系.
    方法:本研究回顾性纳入了302例诊断为急性PE的连续患者。对于每个病人来说,计算MAAGGIC评分.根据MAGGIC评分的中位数将研究人群分为两组。
    结果:MAGGIC评分高的患者在老年人和女性中的比例明显更高,较低的BMI,CAD的存在更高,DM,AFib,HF,HT,CKD,COPD,以及ACEI/ARB和NOAC的使用。使用单变量和多变量分析进行Logistic回归分析,以预测纳入的PE患者的院内和30天死亡率预测因子。对于住院死亡率,舒张压,心率,RV扩张,MAGGIC评分(HR:1.166,95%CI1.077-1.263,p<0.001)和短期死亡率,sPESI和MAGGIC评分(HR:1.925,95%CI1.243-2.983,p:0.003)是急性PE患者不良结局的独立预测因子。
    结论:我们的研究表明,MAGGIC评分可以作为急性肺栓塞的一个有价值的预后工具。
    OBJECTIVE: Acute pulmonary embolism (PE) is a potentially life-threatening condition characterized by the sudden blockage of the pulmonary arteries. Although the MAGGIC risk score has emerged as a valuable tool in predicting outcomes in patients with chronic heart failure, it has also been demonstrated and identified as a prognostic model in various cardiac diseases other than heart failure. In this study, we aimed to investigate the relationship between MAGGIC score and adverse outcomes in patients with PE.
    METHODS: A total of 302 consecutive patients diagnosed with acute PE were retrospectively included in the present study. For each patient, the MAGGIC score was calculated. The study population was divided into two groups according to the median value of MAGGIC score.
    RESULTS: Patients with high MAGGIC score had a significantly higher proportion of elderly and female individuals, lower BMI, higher presence of CAD, DM, AFib, HF, HT, CKD, COPD, and ACEI/ARB and NOAC usage. Logistic regression analyses was carried out using univariate and multivariate analysis to predict the in-hospital and 30-day mortality predictors in the included PE patients. For in-hospital mortality, diastolic blood pressure, heart rate, RV dilatation, and the MAGGIC score (HR: 1.166, 95 % CI 1.077-1.263, p < 0.001) and for short-term mortality, sPESI and the MAGGIC score (HR: 1.925, 95 % CI 1.243-2.983, p:0.003) were found to be independent predictors for adverse outcomes in patients with acute PE.
    CONCLUSIONS: Our study demonstrates that the MAGGIC score can be applied as a valuable prognostic tool for acute pulmonary embolism.

    意识障碍(DoC)代表了一系列神经系统疾病,这些疾病带来了重大的治疗挑战。经皮短期脊髓刺激(SCS)已成为评估和潜在改善意识水平的有前途的实验性诊断治疗方法。然而,这种干预的有效性经常受到电极移位的影响,特别是在宫颈区域,这可能会对治疗结果产生负面影响。
    这项回顾性研究旨在研究DoC患者经皮短期SCS的电极移位是否会影响结果。我们分析了电极移位长度与患者预后之间的关系,以及与各种解剖参数的相关性,包括颈椎的实际长度,线性长度,椎管横径,椎管直径,和C2锥体高度,在接受手术的患者队列中。
    我们的研究结果表明,在预后较好的患者中,电极移位的患者明显减少(p=0.019)。Further,发现电极移位长度与患者预后之间存在线性相关(Rho=0.583,p=0.002),较长的轮班长度与较差的结果相关。与我们的期望相反,测得的解剖参数与电极移位程度之间没有显著关联.然而,在颈椎的实际长度和电极的移位之间发现了趋势(p=0.098)。值得注意的是,在接受经皮短期SCS的DoC患者中,较短的椎管横径与较好的预后显著相关(p=0.033).
    这些结果突出了在对DoC患者进行SCS治疗期间宫颈区域电极稳定性的临床重要性。确保电极的安全放置可能在提高患者预后和减少术后并发症方面发挥关键作用。鉴于与预期的解剖参数缺乏关联,未来的研究应该调查可能影响电极稳定性的其他因素,以优化这种治疗干预.
    UNASSIGNED: Disorders of consciousness (DoC) represent a spectrum of neurological conditions that pose significant treatment challenges. Percutaneous short-term spinal cord stimulation (SCS) has emerged as a promising experimental diagnostic treatment to assess and potentially improve consciousness levels. However, the effectiveness of this intervention is frequently compromised by the shift of electrodes, particularly in the cervical region, which can negatively affect therapeutic outcomes.
    UNASSIGNED: This retrospective study aimed to study if electrodes shift in percutaneous short-term SCS in patients with DoC would affect the outcome. We analyzed the relationship between electrode shift length and patient outcome, as well as the correlation with various anatomical parameters, including the actual length of the cervical spine, linear length, spinal canal transverse diameter, spinal canal diameter, and C2 cone height, in a cohort of patients undergoing the procedure.
    UNASSIGNED: Our findings revealed that in patients with better outcome, there are significant less patient with electrode shift (p = 0.019). Further, a linear correlation was found between the length of electrode shift and patients\' outcome (Rho = 0.583, p = 0.002), with longer shift lengths associated with poorer outcomes. Contrary to our expectations, there was no significant association between the measured anatomical parameters and the extent of electrode shift. However, a trend was found between the actual length of the cervical spine and the shift of the electrode (p = 0.098). Notably, the shorter spinal canal transverse diameter was found to be significantly associated with better outcome in patients with DoC receiving percutaneous short-term SCS (p = 0.033).
    UNASSIGNED: These results highlight the clinical importance of electrode stability in the cervical region during SCS treatment for patients with DoC. Ensuring secure placement of electrodes may play a crucial role in enhancing patients\' outcome and minimize postoperative complications. Given the lack of association with expected anatomical parameters, future research should investigate other factors that could impact electrode stability to optimize this therapeutic intervention.

    这项研究的目的是探索短期的可行性和初步有效性,在初级保健中,手动模式治疗组治疗了77例CBT抵抗情绪和/或焦虑和/或人格障碍(PDs)患者。主要关注的是这种治疗对早期适应不良模式(EMS)的影响,模式,和心理健康。使用YoungSchemaQuestionnaire(YSQ)评估治疗前和治疗后的这些方面,架构模式清单版本1.1(SMI),和症状问卷-48(SQ-48)。治疗包括16个疗程,结合认知,行为,和经验技术。EMS从预处理到后处理显著下降,以及自适应不良的模式。自适应模式增加,心理健康也是如此。关于上述措施的变化,DSM-5分类之间没有显着差异,除了适应不良模式,其中校正后的受试者内效应值表明存在显著的相互作用。因此进行了事后比较,结果表明,与焦虑症和PD患者相比,情绪障碍患者的适应不良模式发生了更多的积极变化(p<0.001)。PDs患者和焦虑症患者之间没有显着差异。我们的研究结果提供了初步证据,在初级保健中,对于CBT抵抗的情绪和/或焦虑和/或PD患者,手动模式疗法可能是一种有效的治疗方法.
    The aim of this study was to explore the feasibility and preliminary effectiveness of a short-term, manualized schema therapy group for 77 patients with CBT-resistant mood and/or anxiety and/or personality disorders (PDs) in primary care. The primary focus was on the effects of this treatment on Early Maladaptive Schemas (EMS), schema modes, and psychological well-being. These aspects were assessed pre-and post-treatment treatment using the Young Schema Questionnaire (YSQ), the Schema Mode Inventory version 1.1 (SMI), and the Symptom Questionnaire-48 (SQ-48). The treatment consisted of 16 sessions, incorporating cognitive, behavioral, and experiential techniques. EMS significantly decreased from pre-treatment to post-treatment, as along with maladaptive schema modes. Adaptive modes increased, as did psychological wellbeing. There were no significant differences between the DSM-5 classifications regarding changes in the aforementioned measures, except for the maladaptive modes, where the value of the corrected within-subject effect indicated a significant interaction. Post hoc comparisons were therefore conducted which showed that patients with a mood disorder experienced more positive changes in maladaptive modes compared to patients with anxiety disorders and PDs (p < 0.001). There was no significant difference between those with PDs and those with Anxiety Disorders. Our findings provide preliminary evidence that short-term, manualized schema therapy might be an effective treatment for patients with CBT-resistant mood and/or anxiety and/or PDs in primary care.

    主要的气态空气污染物与多种原因导致的死亡有关,然而,尚不清楚它们是否在艾滋病毒/艾滋病感染者的过早死亡中起作用。有关HIV/AIDS患者的数据从湖北省疾病预防控制中心收集,在2013年至2020年期间,共有1,467例艾滋病相关死亡(ARD)。日平均二氧化硫(SO2),二氧化氮(NO2),和一氧化碳(CO)通过人工智能算法结合大数据产生。我们采用了时间分层的病例交叉方法和条件逻辑回归模型来研究主要气态空气污染物对ARD的急性影响。每四分位数之间SO2浓度的增加与ARD显着相关,在滞后4天时,相应的比值比(OR)为1.17[95%置信区间(CI):1.01,1.35]。此外,我们的研究结果表明,男性表现出更容易受到SO2和NO2的不利影响,例如,OR分别为1.24(95%CIs:1.05,1.47)和1.16(95%CIs:1.01,1.34),分别。此外,65岁以上的个体更容易受到SO2和CO的影响。此外,我们确定温暖季节是与SO2和NO2相关的死亡率的敏感期。我们的研究提供了有关主要气态空气污染物对ARD的有害影响的新证据。
    Primary gaseous air pollutants have been associated with death from multiple causes, however, it remains unknown if they play a role in premature mortality among individuals living with HIV/AIDS. Data on HIV/AIDS patients were collected from the Hubei Provincial Center for Disease Control and Prevention, with a total of 1,467 AIDS-related deaths (ARD) between 2013 and 2020. Daily mean sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO) were generated by artificial intelligence algorithms combined with big data. We employed a time-stratified case-crossover approach and conditional logistical regression models to investigate the acute effects of primary gaseous air pollutants on ARD. Per interquartile range increase in the concentrations of SO2 was significantly linked with ARD, with a corresponding odds ratio (OR) of 1.17 [95% confidence intervals (CIs): 1.01, 1.35] at lag 4 day. Furthermore, our findings indicated that males exhibited a heightened vulnerability to the adverse effects of SO2 and NO2, for example, the ORs were 1.24 (95% CIs: 1.05, 1.47) and 1.16 (95% CIs: 1.01, 1.34), respectively. Moreover, individuals aged over 65 years were more susceptible to SO2 and CO. Additionally, we identified the warm season as a sensitive period for mortality associated with SO2 and NO2. Our study furnished fresh evidence regarding the detrimental effects of primary gaseous air pollutants on ARD.

    背景:先前研究孤独与抑郁症状之间的关系的研究通常将这些结构视为静态特征而不是动态状态。目前的研究集中在短期,孤独和抑郁症状之间的潜在联系,同时分析潜在的性别差异。
    方法:我们对来自FRequent晚年健康评估(FRAIL70+)研究中收集的七个双周评估的面板数据进行了建模。在基线,在奥地利,样本量为N=426名70岁或以上的社区居住老年人。使用潜在变化评分建模框架分析了孤独与抑郁症状之间的关系。
    结果:关于抑郁症状,与男性相比,女性在三个月内表现出更高的初始水平和更多的变化。男女的孤独感随时间变化不大。此外,在某一特定时间点更高的孤独感与女性两周后抑郁症状加速增加有关,而男性则没有。
    结论:孤独似乎是未来抑郁症状增加的潜在决定因素。男性和女性之间观察到的不同影响表明,在抑郁症状的短期波动及其潜在机制方面存在潜在的性别差异。
    BACKGROUND: Previous research examining the relationship between loneliness and depressive symptoms often treated these constructs as static traits rather than dynamic states. The current study focused on the short-term, prospective link between loneliness and depressive symptoms, while also analyzing potential gender differences.
    METHODS: We modeled panel data from seven bi-weekly assessments gathered in the FRequent health Assessment In Later life (FRAIL70+) study. At baseline, the sample size amounted to N = 426 community-dwelling older adults aged 70 years or older in Austria. The relationship between loneliness and depressive symptoms was analyzed using a latent change score modeling framework.
    RESULTS: As regards depressive symptoms, women showed higher initial levels and more change across the three months than men. Loneliness did not considerably change across time for both sexes. Moreover, greater levels of loneliness at a given point in time were associated with an accelerated increase in depressive symptoms two weeks later in women but not in men.
    CONCLUSIONS: Loneliness appeared to be a potential determinant of future increases in depressive symptoms. The varying effects observed between men and women suggest potential gender differences in short-term fluctuations of depressive symptoms and their underlying mechanisms.

    由于天气条件的不确定性和高维数据的非线性,以及需要为电力系统提供持续稳定的电力供应,传统的回归分析和时间序列预测方法已不能满足当今光伏发电预测的高精度要求。为了显著提高短期光伏输出功率的预测精度,本文以澳大利亚某光伏电站生成数据为研究对象,提出了一种基于时间卷积网络和门控循环单元混合模型的短期光伏功率预测方法。首先,时间卷积网络(TCN)用作空间特征提取层,并嵌入了高效的信道注意网络(ECANET),以增强卷积网络的特征捕获能力。然后,GRU用于提取用于最终预测的定时信息。最后,基于实验验证,根据三个性能评估指标,TCN-ECANet-GRU方法在一年中的所有四个季节中通常优于其他基线模型:归一化均方根误差(RMSE),归一化平均绝对误差(MAE)和决定系数(R2)。最好的RMSE,MAE和R2分别达到0.0195、0.0128和99.72%,分别,最大改进11.32%,8.57%和0.38%,分别,超过那些次优模型。因此,该模型有效地提高了预测精度。使用所提出的方法,本文以3、6和9步的多步预测作为结尾,这也表明该方法显著优于其他模型。
    Due to the uncertainty of weather conditions and the nonlinearity of high-dimensional data, as well as the need for a continuous and stable power supply to the power system, traditional regression analysis and time series forecasting methods are no longer able to meet the high accuracy requirements of today\'s PV power forecasting. To significantly improve the prediction accuracy of short-term PV output power, this paper proposes a short-term PV power forecasting method based on a hybrid model of temporal convolutional networks and gated recurrent units with an efficient channel attention network (TCN-ECANet-GRU) using the generated data of an Australian PV power station as the research object. First, temporal convolutional networks (TCNs) are used as spatial feature extraction layers, and an efficient channel attention network (ECANet) is embedded to enhance the feature capture capability of the convolutional network. Then, the GRU is used to extract the timing information for the final prediction. Finally, based on the experimental validation, the TCN-ECANet-GRU method generally outperformed the other baseline models in all four seasons of the year according to three performance assessment metrics: the normalized root mean square error (RMSE), normalized mean absolute error (MAE) and coefficient of determination (R2). The best RMSE, MAE and R2 reached 0.0195, 0.0128 and 99.72%, respectively, with maximum improvements of 11.32%, 8.57% and 0.38%, respectively, over those of the suboptimal model. Therefore, the model proposed in this paper is effective at improving prediction accuracy. Using the proposed method, this paper concludes with multistep predictions of 3, 6, and 9 steps, which also indicates that the proposed method significantly outperforms the other models.

    随着技术和工业的发展,全球空气污染问题已经变得难以忽视。我们调查了空气污染物浓度与每日全因死亡率之间的关系,并按性别进行了分层分析。年龄,和季节。六种空气污染物的数据[细颗粒物(PM2.5),可吸入颗粒物(PM10),二氧化氮(NO2),二氧化硫(SO2),臭氧(O3)和一氧化碳(CO)]和2015年至2019年广州的每日死亡率,中国。使用准泊松广义加性模型进行时间序列研究,以检查环境污染物浓度与死亡率之间的关系。分析中包括296,939名个体的死亡率数据。结果表明,PM2.5,PM10,SO2,O3,NO2和CO的浓度增加10μg/m3对应于0.84%[95%置信区间(CI):0.47,1.21%],0.70%(0.44,0.96%),3.59%(1.77、5.43%),0.21%(0.05,0.36%),1.06%(0.70,1.41%),和0.05%(0.02,0.09%),分别。六种空气污染物对男性个体的影响比女性个体更显著,凉爽的季节比温暖的季节,和75岁或75岁以上的人。PM2.5,PM10,SO2和NO2均与肿瘤,循环和呼吸系统疾病有关。双污染物模型发现,PM2.5,PM10和NO2可能独立影响死亡风险。结果表明,PM2.5、PM10和NO2暴露可能会增加广州地区每日全因死亡率过高的风险。
    With the development of technology and industry, the problem of global air pollution has become difficult to ignore. We investigated the association between air pollutant concentrations and daily all-cause mortality and stratified the analysis by sex, age, and season. Data for six air pollutants [fine particulate matter (PM2.5), inhalable particles (PM10), nitric dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and carbon monoxide (CO)] and daily mortality rates were collected from 2015 to 2019 in Guangzhou, China. A time-series study using a quasi-Poisson generalized additive model was used to examine the relationships between environmental pollutant concentrations and mortality. Mortality data for 296,939 individuals were included in the analysis. The results showed that an increase of 10 μg/m3 in the concentrations of PM2.5, PM10, SO2, O3, NO2, and CO corresponded to 0.84% [95% confidence interval (CI): 0.47, 1.21%], 0.70% (0.44, 0.96%), 3.59% (1.77, 5.43%), 0.21% (0.05, 0.36%), 1.06% (0.70, 1.41%), and 0.05% (0.02, 0.09%), respectively. The effects of the six air pollutants were more significant for male individuals than female individuals, the cool season than the warm season, and people 75 years or older than those younger than 75 years. PM2.5, PM10, SO2, and NO2 were all associated with neoplasms and circulatory and respiratory diseases. The two-pollutant models found that PM2.5, PM10, and NO2 may independently affect the risk of mortality. The results showed that exposure to PM2.5, PM10 and NO2 may increase the risk of daily all-cause excessive mortality in Guangzhou.
