    这一贡献旨在设计和验证一种新的绿色,便宜,以及快速测定不同基质中抗GERD药物泮托拉唑的方法。新型S和N掺杂碳纳米材料(S,N-CNM)是通过微波辐射广泛使用的家庭来源的混合物制备的。值得注意的是,利用尿素和硫脲与食糖的混合物产生S,N-CNM表现出最大的量子产率(54%),亲水性,以及稳定,同质,和小粒度分布。傅里叶变换红外光谱,透射电子显微镜,分光光度法,和荧光光谱法用于表征S,N-CNM。S,N-CNMs已被用作关闭荧光探针,通过内部过滤效应和静态猝灭机制的协同作用来确定泮托拉唑。在1.0-25.0µg/mL的范围内,荧光猝灭与泮托拉唑浓度线性相关,检出限为0.16µg/mL。在存在物质可变性的情况下,开发的探针对泮托拉唑表现出良好的选择性。因此,用于片剂和小瓶中泮托拉唑的质量控制,平均回收率为100.10±0.77%和100.33±0.92%,分别。此外,成功实施了泮托拉唑片剂含量均匀度的检测。此外,准备好的S,在简单的蛋白沉淀步骤后,N-CNM已成功用于分析人血浆中的泮托拉唑,回收率为97.88±5.72%。最近的工具对所开发方法的绿色和蓝色进行了积极评估,表明所开发方法的生态友好性和适用性。
    This contribution aims to design and validate a new green, cheap, and fast approach for determining the anti-GERD drug pantoprazole in different matrices. New S and N-doped carbon nanomaterials (S,N-CNMs) have been prepared via microwave irradiation of a mixture of widely available household sources. Remarkably, the utilization of a blend of carbamide and thiocarbamide with table sugar yields S,N-CNMs exhibiting the utmost quantum yield (54 %), hydrophilicity, as well as stable, homogeneous, and diminutive particle size distribution. Fourier transform infrared spectroscopy, transmission electron microscopy, spectrophotometry, and fluorescence spectroscopy were applied to characterize the S,N-CNMs. The S,N-CNMs have been used as a turn-off fluorescence probe to determine pantoprazole via a synergism of the inner filter effect and static quenching mechanisms. The fluorescence quenching is linearly correlated to pantoprazole concentration over the range of 1.0-25.0 µg/mL with a detection limit of 0.16 µg/mL. The developed probe exhibited good selectivity for pantoprazole in the presence of variability of substances. Therefore, it was applied for quality control of pantoprazole in pharmaceutical tablets and vials with an average recovery % of 100.10 ± 0.77 % and 100.33 ± 0.92 %, respectively. Moreover, it was successfully implemented to examine the content uniformity of pantoprazole in tablets. Furthermore, the prepared S,N-CNMs have been successfully used for the analysis of pantoprazole in human plasma after a simple protein precipitation step with a recovery % of 97.88 ± 5.72 %. The greenness and blueness of the developed method have been positively assessed by recent tools showing the eco-friendliness and applicability of the developed method.

    由于它们容易退化,食品配方中的维生素水平可能与成品中的维生素水平不同。维生素水平会受到加工和储存的影响。在这项工作中,使用简单有效的稳定性指示HPLC方法同时估计StrongB50®薄膜包衣片剂的成分。StrongB50®薄膜包衣片剂含有硫胺素(VB1),核黄素(VB2),泛酸钙(VB5),吡哆醇(VB6),维生素C(VC),叶酸(FA),生物素(BT),肌醇(IS),烟酸(NC),对氨基苯甲酸(PB),氰钴胺(B12),酒石酸胆碱,和葡萄糖酸铁.HypersilBDSC18柱用于实现合理的分离。利用流动相(A)和(B),流动相(A)由0.015M己烷磺酸钠盐+0.1%三乙胺组成,使用正磷酸将pH调节至(2.9),而(B)系统由乙腈组成。使用国际协调会议(ICH)参数评估方法的验证,其中线性,准确度,选择性,并对该方法的鲁棒性进行了研究。相关性高于0.99,准确性结果范围为97.6至102.8%,并且以μg/mL为单位确定每种维生素的检测和定量限(LOD和LOQ)值,FA和BT除外,以ng/mL为单位。LOD值在0.006至15.08μg/mL之间,而LOQ值在0.031至49.77μg/mL的范围内。在应激条件下进行稳定性研究并计算降解百分比。Where,VB5,VB6,FA和PB,VC,和NC是最可降解的维生素。使用现代RGB12算法进行的白度评估比较了我们的方法和Sasaki等人报道的旧方法。,2020年。在分析性能方面,比较有利于我们新开发的方法,实用性和绿色性。此外,使用AGREE和GAPI软件来评估该方法的绿色性。很明显,彩色象形图的结果证实了低危险影响,并且新方法更绿色,AGREE评分为0.66。此外,通过蓝色适用性等级指数(BAGI)工具得出新型HPLC方法的功能性和适用性,最终得分为82.5.
    Due to their susceptibility to degradation, vitamin levels in food formulations may differ from those found in the finished product. Vitamin levels can be impacted by processing and storage. In this work, the ingredients of Strong B50 ® film-coated tablets were estimated simultaneously using simple efficient stability indicating HPLC method. Strong B50 ® film-coated tablets contain thiamine (VB1), riboflavin (VB2), calcium pantothenate (VB5), pyridoxine (VB6), vitamin C (VC), folic acid (FA), biotin (BT), inositol (IS), niacin (NC), para-aminobenzoic acid (PB), cyanocobalamine (B12), choline bitartarate, and iron gluconate. Hypersil BDS C18 column was used for achieving reasonable separation. Mobile phases (A) and (B) were utilized, the mobile phase (A) consisted of 0.015 M Hexane sulfonic acid sodium salt + 0.1 % Triethylamine and orthophosphoric acid was used to adjust the pH to (2.9) while (B) system consisted of acetonitrile. Validation of the method was assessed using International Conference of Harmonization (ICH) parameters, where linearity, accuracy, selectivity, and robustness of the method were investigated. Correlations were above 0.99, accuracy results ranged from 97.6 to 102.8 % and limits for detection and quantitation (LOD and LOQ) values were determined for each vitamin in μg/mL except for FA and BT in ng/mL. LOD values were between 0.006 and 15.08 μg/mL while LOQ values ranged from 0.031 to 49.77 μg/mL. Stability studies were conducted under stressed conditions and degradation percentages were computed. Where, VB5, VB6, FA and PB, VC, and NC were the most degradable vitamins. Whiteness evaluation using the modern RGB 12 algorithm compared our method and the old reported one by Sasaki et al., 2020. The comparison favored our newly developed method in terms of analytical performance, practical applicability and greenness. Besides, AGREE and GAPI soft wares were used to assess the greenness of the method. It was clear that the results of colored pictograms confirm low hazardous impact and that the new method is greener with AGREE score of 0.66. Furthermore, the functionality and applicability of the novel HPLC approach were concluded via the Blue Applicability Grade Index (BAGI) tool with a final score of 82.5.

    全球非传染性疾病(NCDs)的增加是一个严重的公共卫生问题。新出现的证据表明,暴露于自然环境可能通过多种途径降低发展非传染性疾病的风险。本系统评价旨在综合和评估有关绿色和蓝色空间暴露与非传染性疾病相关的入院之间的关联的观察证据。在Embase(Ovid)进行了全面的文献检索策略,PubMed,和WebofScience。使用导航指南方法评估偏倚风险和证据质量,专门为环境健康研究设计的方法。在3060个搜索结果中,共包括17篇文章。值得注意的是,大多数研究(n=14;82.4%)从2020年开始发表。大多数研究在美国(n=6;35.3%)和中国(n=4;23.5%)进行。通过所有研究评估了对绿色空间的暴露,而只有三个包含蓝色空间。在研究设计方面,近一半的研究采用队列设计(n=8;47.1%),其次是病例交叉设计(n=3,17.6%)。超过75%的纳入研究(n=13)在偏倚风险评估中具有较高或可能较高的评级。这些研究涵盖了不同的非传染性疾病结局领域;心血管疾病(CVD)(n=10),呼吸系统疾病(RSD)(n=2),与热有关的疾病(n=1),代谢性疾病(n=2),癌症(n=1),神经退行性疾病(NDDs)(n=2),和精神健康障碍(n=2)。本审查表明,蓝色空间暴露与NCD住院之间的明确联系并不明显。然而,暴露于绿色空间似乎主要具有保护作用,尽管关联的方向在不同的结果领域有所不同。结果领域之间的异质性以及有限的研究数量,强调需要更有力的证据。
    The global increase in non-communicable diseases (NCDs) presents a critical public health concern. Emerging evidence suggests that exposure to natural environments may reduce the risk of developing NCDs through multiple pathways. The present systematic review aims to synthesize and evaluate the observational evidence regarding associations between exposure to green and blue spaces and hospital admissions related to NCDs. A comprehensive literature search strategy was conducted in Embase (Ovid), PubMed, and Web of Science. The risk of bias and quality of the evidence were assessed using The Navigation Guide methodology, an approach specifically designed for environmental health research. Of 3060 search results, 17 articles were included. Notably, the majority of the studies (n = 14; 82.4%) were published from 2020 onwards. Most studies were conducted in the United States (n = 6; 35.3%) and China (n = 4; 23.5%). Exposure to green spaces was assessed through all studies, while only three included blue spaces. In terms of study design, cohort design was employed in nearly half of the studies (n = 8; 47.1%), followed by case-crossover design (n = 3, 17.6%). Over 75% of the included studies (n = 13) had a high or probably high rating in the risk of bias assessment. The studies encompassed diverse NCD outcome domains; cardiovascular diseases (CVDs) (n = 10), respiratory diseases (RSDs) (n = 2), heat-related diseases (n = 1), metabolic diseases (n = 2), cancer (n = 1), neurodegenerative diseases (NDDs) (n = 2), and mental health disorders (n = 2). The present review suggests that a clear link between blue space exposure and NCD hospital admissions is not evident. However, exposure to green spaces appears to predominantly have a protective effect, although the direction of the association varies across different outcome domains. The heterogeneity among the outcome domains together with the limited number of studies, emphasizes the need for more robust evidence.
