Age-related ocular diseases, including diabetic retinopathy (DR), age-related macular degeneration (AMD), cataract and glaucoma may lead to visual impairment and even to blindness. Metabolic diseases, such as obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) have emerged as potential risk factors of age-related ocular diseases, especially DR. Visceral adiposity has been associated with increased risk of DR and AMD in most clinical studies, although body mass index has to-date provided conflicting association with DR and AMD. In addition, obesity is recognized as a risk factor of cataract and glaucoma. Similarly to obesity, MASLD appears to be associated with DR in patients with type 1 diabetes mellitus, but probably not in those with type 2 diabetes mellitus. A potential positive association between MASLD and AMD, glaucoma and cataract is supported by limited evidence to-date, thus needing further investigation. Altered secretion patterns of adipokines (adiponectin, leptin, lipocalin-2, resistin) and hepatokines [adropin, fetuin-A, fibroblast growth factor (FGF)-21, retinol binding protein (RBP)-4] seem to disrupt ocular homeostasis and contribute to the development of age-related ocular diseases in the context of obesity and MASLD. In this regard, novel adipokine-based and hepatokine-based therapies may be added to the treatment options for ocular diseases in the future. This narrative review aimed to summarize evidence on the interconnection of obesity and MASLD with age-related ocular diseases, with a specific focus on the roles of adipokines and hepatokines as mediators of these potential associations.
与年龄相关的眼部疾病,包括糖尿病视网膜病变(DR)、年龄相关性黄斑变性(AMD)、白内障和青光眼,都可能导致视力受损,甚至失明。代谢性疾病,如肥胖和代谢功能障碍相关的脂肪变性肝病(MASLD)已成为与年龄相关的眼部疾病,尤其是DR的潜在危险因素。在大多数临床研究中,内脏脂肪与DR和AMD的风险增加有关,尽管迄今为止,体重指数与DR和AMD的关联并不一致。此外,肥胖被认为是白内障和青光眼的危险因素。与肥胖类似,MASLD似乎与1型糖尿病患者的DR有关,但可能与2型糖尿病患者无关。MASLD与黄斑变性、青光眼和白内障之间的潜在正相关目前证据有限,因此需要进一步研究。脂肪因子(脂联素、瘦素、脂钙素-2、抵抗素)和肝因子(adropin、胎儿素- a、成纤维细胞生长因子(FGF)-21、视黄醇结合蛋白(RBP)-4)分泌模式的改变似乎会破坏眼部稳态,并在肥胖和MASLD的背景下促进与年龄相关的眼部疾病的发展。在这方面,新的基于脂肪因子和基于肝因子的治疗方法可能会在未来增加到眼部疾病的治疗选择中。这篇叙述性综述旨在总结肥胖和MASLD与年龄相关眼部疾病之间相互联系的证据,并特别关注脂肪因子和肝因子作为这些潜在关联的介质的作用。

Background

The incidence of metabolic dysfunction-associated steatohepatitis (MASH) is increasing, with an incompletely understood pathophysiology involving multiple factors, particularly innate and adaptive immune responses. Given the limited pharmacological treatments available, identification of novel immune metabolic targets is urgently needed. In this study, we aimed to identify hub immune-related genes and potential biomarkers with diagnostic and predictive value for MASH patients.

Methods

The GSE164760 dataset from the Gene Expression Omnibus was utilized for analysis, and the R package was used to identify differentially expressed genes. Immune-related differentially expressed genes (IR-DEGs) were identified by comparing the overlap of differentially expressed genes with well-known immune-related genes. Furthermore, the biological processes and molecular functions of the IR-DEGs were analyzed. To characterize the hub IR-DEGs, we employed a protein-protein interaction network. The diagnostic and predictive values of these hub IR-DEGs in MASH were confirmed using GSE48452 and GSE63067 datasets. Finally, the significance of the hub IR-DEGs was validated using a mouse model of MASH.

Results

A total of 91 IR-DEGs were identified, with 61 upregulated and 30 downregulated genes. Based on the protein-protein interaction network, FN1, RHOA, FOS, PDGFRα, CCND1, PIK3R1, CSF1, and FGF3 were identified as the hub IR-DEGs. Moreover, we found that these hub genes are closely correlated with immune cells. Notably, the validation across two independent cohorts as well as a murine MASH model confirmed their high diagnostic potential.

Conclusion

The hub IR-DEGs, such as FN1, RHOA, FOS, PDGFRα, CCND1, PIK3R1, CSF1, and FGF3, may enhance the diagnosis and prognosis of MASH by modulating immune homeostasis.
代谢功能障碍相关脂肪性肝炎(MASH)的发病率正在增加,涉及多种因素的病理生理学尚不完全清楚,特别是先天和适应性免疫反应。鉴于现有的药物治疗有限,迫切需要鉴定新的免疫代谢靶点。在这项研究中,我们的目的是确定中心免疫相关基因和潜在的生物标志物,对MASH患者具有诊断和预测价值。方法利用基因表达图谱(Gene Expression Omnibus)中的GSE164760数据集进行分析,并利用R包进行差异表达基因的鉴定。通过比较差异表达基因与已知免疫相关基因的重叠,鉴定免疫相关差异表达基因(IR-DEGs)。并对IR-DEGs的生物学过程和分子功能进行了分析。为了表征枢纽IR-DEGs,我们采用了蛋白质-蛋白质相互作用网络。使用GSE48452和GSE63067数据集证实了这些枢纽IR-DEGs在MASH中的诊断和预测价值。最后,利用小鼠MASH模型验证了枢纽IR-DEGs的意义。结果共鉴定出91个ir - deg,其中61个基因上调,30个基因下调。基于蛋白相互作用网络,FN1、RHOA、FOS、PDGFRα、CCND1、PIK3R1、CSF1和FGF3被鉴定为枢纽IR-DEGs。此外,我们发现这些中心基因与免疫细胞密切相关。值得注意的是,通过两个独立队列以及小鼠MASH模型的验证证实了它们的高诊断潜力。结论FN1、RHOA、FOS、PDGFRα、CCND1、PIK3R1、CSF1、FGF3等中枢ir - deg可能通过调节免疫稳态,提高MASH的诊断和预后。

Background

Dry fasting (DF) presents three primary risks: hypovolemia, hypertonicity, and hypoglycemia. The first two have been shown to be effectively compensated, and the respective mechanisms have been studied. The behavior of glucose has only been roughly described, while the hypoglycemia compensation mechanisms remain unexplored.

Objectives

Studying the glucose behavior, the hypoglycemia compensation mechanisms, and the insulin resistance during DF.

Methods

Following parameters were daily monitored in ten participants undergoing a 5-day DF: Weight, body circumferences, glucose, creatinine clearance (GFR), insulin, HOMA-IR, acetoacetate in 24-h urine, glucagon, growth hormone (GH), IGF-1, TSH, T4, T3, leptin, cholesterol, LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C), triglycerides, and the enzymes LDH, CPK, SGPT, SGOT, and γGT.

Results

Weight, body circumferences, TSH, T3, and T4 decreased to minima on Day 5; insulin and HOMA-IR decreased, reaching minima on Day 4; GH, cholesterol, LDL-C, and acetoacetate increased to maxima on Day 5; Glucagon, IGF-1, and GFR increased, presenting maxima on Day 4; Glucose, leptin, and triglycerides exhibited biphasic profiles with minima on Days 3, 3, and 2, respectively; HDL-C, LDH, CPK, SGPT, SGOT, and γGT showed minimal or non-significant changes.

Conclusion

A comprehensive description of glucose behavior and the hypoglycemia compensation mechanisms in DF were presented. DF decreased insulin resistance, likely by improving the blood – cell interphase, and enhanced GFR. The increase in LDL-C, tissue-protecting IGF-1, and late increase in leptin and triglycerides were unexpected. The results may inform the development of novel therapeutic approaches for obesity, metabolic syndrome, type-2-diabetes, non-alcoholic fatty liver disease, adiposity, and atheromatous diseases.
干禁食(DF)有三个主要风险:低血容量、高渗和低血糖。前两者已被证明是有效补偿的,并对各自的机制进行了研究。葡萄糖的行为仅被粗略描述,而低血糖补偿机制仍未探索。目的研究糖尿病患者的血糖行为、低血糖代偿机制及胰岛素抵抗。方法对10名参与者进行为期5天的DF,每天监测以下参数:体重、体围、血糖、肌酐清除率(GFR)、胰岛素、HOMA-IR、24小时尿乙酰乙酸、胰高血糖素、生长激素(GH)、IGF-1、TSH、T4、T3、瘦素、胆固醇、ldl -胆固醇(LDL-C)、hdl -胆固醇(HDL-C)、甘油三酯、LDH、CPK、SGPT、SGOT和γGT。结果体重、体围、TSH、T3、T4在第5天降至最低;胰岛素和HOMA-IR下降,在第4天达到最低;生长激素、胆固醇、LDL-C和乙酰乙酸在第5天达到最大值;胰高血糖素、IGF-1和GFR升高,在第4天达到最大值;葡萄糖、瘦素和甘油三酯分别在第3天、第3天和第2天表现出最小的双相特征;HDL-C、LDH、CPK、SGPT、SGOT和γGT的变化最小或不显著。结论对糖尿病患者的葡萄糖行为和低血糖代偿机制有较全面的描述。DF降低胰岛素抵抗,可能是通过改善血细胞间期和提高GFR。LDL-C、保护组织的IGF-1的升高以及瘦素和甘油三酯的晚期升高都是出乎意料的。该结果可能为肥胖症、代谢综合征、2型糖尿病、非酒精性脂肪性肝病、肥胖和动脉粥样硬化疾病的新治疗方法的发展提供信息。

This study investigates the association of allelic and genotypic variations of rs121912717 and rs373056577 within APOA1 and APOA2 genes, respectively with the risk of type 2 diabetes (T2D). In this cross-sectional study, real-time quantitative PCR with specific Taqman probes was used to determine the genotypic and allelic frequencies of rs121912717 and rs373056577 in 300 unrelated Bangladeshi individuals (Healthy = 144, T2D patients = 156). Logistic regression analysis was performed to investigate the association of genotypic and allelic frequencies of these SNPs with respect to T2D under different inheritance models. Neither allelic nor genotypic frequencies of rs121912717 within APOA1 showed any significant association with T2D. Genotypes with respect to rs373056577 within APOA2 showed significant association with the risk of T2D under co-dominant heterozygous model (GG vs GA) [OR (95 %CI): 2.64 (1.32–5.59), p = 0.008], dominant [OR (95 %CI): 2.31 (1.24–4.49), p = 0.01] and over-dominant [OR (95 %CI): 2.62 (1.31–5.53), p = 0.008] models without adjusting for age, gender and BMI. After adjusting for age, gender and BMI, the A allele of rs373056577 showed significant association with T2D only in the dominant model [OR (95 %CI): 3.20 (1.12–10.51), p = 0.04]. Also, A allele of rs373056577 demonstrated significant association with the risk of T2D compared to allele G with [OR (95 %CI): 2.90 (1.15–8.14), p = 0.03] and without adjusting for confounders [OR (95 %CI): 1.97 (1.14–3.52), p = 0.02]. The genotypic frequency was significantly associated with T2D in codominant, dominant, and overdominant models in male participants when a gender-stratified analysis was conducted for rs373056577. However, when the logistic regression analysis was adjusted for age and BMI, the association was not significant in any of the models with respect to rs373056577 for male participants. On the other hand, gender-stratified regression analyses revealed no significant association with T2D before and after adjusting for age and BMI with respect to both allelic and genotypic frequencies of rs121912717. Individuals with CT genotype of rs121912717 had significantly higher triglyceride levels (322.2 mg/dL) compared to those harboring CC genotype (202.8 mg/dL) with or without adjusting for age, gender, BMI and disease status of the study participants. In conclusion, this study revealed that individuals harboring the allele A of rs373056577 possessed an increased risk of developing T2D and individuals having CT genotype of rs121912717 had increased triglyceride levels. The result of this study needs to be validated in a larger cohort for a more robust assessment.
本研究探讨了APOA1和APOA2基因中rs121912717和rs373056577等位基因和基因型变异与2型糖尿病(T2D)风险的关系。在本横断面研究中,采用特异性Taqman探针的实时定量PCR测定了300名孟加拉国无亲缘关系个体(健康= 144,T2D患者= 156)rs121912717和rs373056577的基因型和等位基因频率。采用Logistic回归分析研究不同遗传模式下这些snp的基因型和等位基因频率与T2D的关系。APOA1内rs121912717的等位基因频率和基因型频率均未显示与T2D有显著关联。APOA2中rs373056577基因型在共显性杂合模型(GG vs GA) [OR (95% CI): 2.64 (1.32-5.59), p = 0.008]、显性模型[OR (95% CI): 2.31 (1.24-4.49), p = 0.01]和过显性模型[OR (95% CI): 2.62 (1.31-5.53), p = 0.008]下与T2D风险显著相关,不考虑年龄、性别和BMI。在调整年龄、性别和BMI后,rs373056577等位基因A与T2D仅在优势模型中显示显著相关[OR (95% CI): 3.20 (1.12-10.51), p = 0.04]。此外,与等位基因G相比,rs373056577等位基因A与T2D风险显著相关[OR (95% CI): 2.90 (1.15-8.14), p = 0.03],且未调整混杂因素[OR (95% CI): 1.97 (1.14-3.52), p = 0.02]。在对rs373056577进行性别分层分析时,基因型频率与男性参与者共显性、显性和过显性模型中的T2D显著相关。然而,当对年龄和BMI进行调整的逻辑回归分析时,在任何模型中,关于男性参与者的rs373056577的关联都不显著。另一方面,性别分层回归分析显示,rs121912717的等位基因和基因型频率在调整年龄和BMI前后与T2D无显著相关性。无论是否调整研究参与者的年龄、性别、BMI和疾病状态,rs121912717 CT基因型个体的甘油三酯水平(322.2 mg/dL)明显高于CC基因型个体(202.8 mg/dL)。综上所述,本研究显示携带rs373056577等位基因A的个体发生T2D的风险增加,携带rs121912717 CT基因型的个体甘油三酯水平升高。这项研究的结果需要在更大的队列中进行验证,以获得更可靠的评估。

Background

Diabetic ketoacidosis is a severe complication of diabetes that can threaten life and has a considerable effect on healthcare systems, especially in developing nations such as Ethiopia. Although it is clinically significant, comprehensive data on the factors that lead to unsatisfactory treatment outcomes in diabetic ketoacidosis patients in Ethiopia are lacking. This review aims to investigate and evaluate unsatisfactory treatment outcomes and multiple contributing factors related to diabetic ketoacidosis among patients with diabetes in Ethiopia. This review seeks to identify these factors to provide insights that can guide improvements in the management and treatment of diabetic patients.

Methods

Articles documenting unfavorable treatment outcomes and related aspects of diabetic ketoacidosis among Ethiopian diabetes patients were meticulously sought from various databases, including PubMed/MEDLINE, the Cochrane Library, Science Direct, HINARI, Google Scholar, and gray literature. After the data were extracted, they were imported into Stata software version 17 for analysis. The Cochrane Q test and I2 statistic were used to evaluate heterogeneity.

Results

A total of 580 duplicates were eliminated from the initial set of 1578 papers obtained from PubMed (3), Google Scholar (1,550), HINARI (11), Science Direct (13), and the Cochrane Library (1). The pooled prevalence of poor treatment outcomes for diabetic ketoacidosis was 8 %. Key risk factors for poor treatment outcomes included a Glasgow Coma Scale (GCS) score of less than 15 (POR = 3.16; 95 % CI: 1.52–4.80), sepsis (POR = 2.92; 95 % CI: 1.12–4.72), and comorbidities (POR = 3.66; 95 % CI: 1.64–5.68).

Conclusion

The pooled prevalence of poor treatment outcomes of diabetic ketoacidosis in Ethiopia was high. A GCS score of less than 15, sepsis, and comorbidities were identified as significant risk factors for poor treatment outcomes in diabetic ketoacidosis patients. Addressing and minimizing these factors could help reduce the incidence of poor treatment outcomes in diabetic ketoacidosis patients in Ethiopia.
糖尿病酮症酸中毒是糖尿病的一种严重并发症,可威胁生命,对医疗保健系统有相当大的影响,特别是在埃塞俄比亚等发展中国家。虽然具有临床意义,但埃塞俄比亚缺乏导致糖尿病酮症酸中毒患者治疗结果不满意的因素的综合数据。本综述旨在调查和评价埃塞俄比亚糖尿病患者不满意的治疗结果和与糖尿病酮症酸中毒相关的多种因素。本综述旨在确定这些因素,为指导糖尿病患者管理和治疗的改进提供见解。方法从PubMed/MEDLINE、Cochrane图书馆、Science Direct、HINARI、谷歌Scholar和灰色文献等数据库中仔细检索记录埃塞俄比亚糖尿病患者不良治疗结果和糖尿病酮症酸中毒相关方面的文章。数据提取后,导入Stata软件版本17进行分析。采用Cochrane Q检验和I2统计量评价异质性。结果从PubMed(3)、谷歌Scholar(1550)、HINARI(11)、Science Direct(13)和Cochrane图书馆(1)获得的1578篇论文中,共剔除了580个重复。糖尿病酮症酸中毒治疗不良的总发生率为8%。不良治疗结果的关键危险因素包括格拉斯哥昏迷评分(GCS)低于15分(POR = 3.16;95% CI: 1.52-4.80),脓毒症(POR = 2.92;95% CI: 1.12-4.72),合并症(POR = 3.66;95% ci: 1.64-5.68)。结论埃塞俄比亚糖尿病酮症酸中毒治疗不良的总发生率较高。GCS评分小于15、脓毒症和合并症被认为是糖尿病酮症酸中毒患者治疗结果不佳的重要危险因素。解决和尽量减少这些因素可能有助于减少埃塞俄比亚糖尿病酮症酸中毒患者治疗结果不佳的发生率。

Background

Holocarboxylase Synthetase Deficiency (HCSD) is an uncommon autosomal recessive genetic disorder that manifests with symptoms such as metabolic acidosis, lethargy, hypotonia, seizures, and persistent rashes, typically emerging during infancy. The HLCS gene has been identified as the source of pathogenic mutations associated with this condition. Cobalamin C (cblC) deficiency is another rare autosomal recessive disorder resulting from defects in cobalamin metabolism, attributable to mutations in the MMACHC gene. This disorder often leads to methylmalonic aciduria and homocystinuria and is classified into early-onset and late-onset types. The late-onset type is characterized by acute or chronic progressive neurological symptoms and behavioral disturbances. To date, there have been no documented cases worldwide of individuals diagnosed with both HCSD and cobalamin C deficiency.

Case presentation

This report details the case of an 11-year-and-9-month-old female patient from China who presented with symptoms including vomiting, altered consciousness, and a rash. Laboratory evaluations indicated the presence of metabolic acidosis, methylmalonic aciduria, and homocystinuria. Genetic analysis revealed mutations in the MMACHC gene: c.482G > A (p.R161Q) and c.567dup (p.I190Yfs∗13). Additionally, two previously unreported mutations in the HLCS gene, c.1922G > T (p.G641V) and c.1754C > T (p.P585L), were identified. She was diagnosed with Holocarboxylase Synthetase Deficiency and Cobalamin C deficiency. The child showed significant improvement following treatment with hydroxocobalamin, betaine, and biotin.

Conclusion

This article reports a case of adolescent onset HCSD and cobalamin C deficiency. Treatment with hydroxocobalamin, betaine, and biotin is effective. Two novel mutations in the HLCS gene causative for HCSD have been reported, providing a broader foundation for mutational screening and offering insights into the diagnosis and treatment of similar disorders.
背景:全新羧化酶合成酶缺乏症(HCSD)是一种罕见的常染色体隐性遗传疾病,其症状表现为代谢性酸中毒、嗜睡、低血压、癫痫发作和持续性皮疹,通常出现在婴儿期。HLCS基因已被确定为与此病相关的致病性突变的来源。钴胺素C (cblC)缺乏是另一种罕见的常染色体隐性遗传病,由钴胺素代谢缺陷引起,可归因于MMACHC基因突变。这种疾病常导致甲基丙二酸尿和同型半胱氨酸尿,分为早发型和晚发型。迟发型的特点是急性或慢性进行性神经症状和行为障碍。迄今为止,世界范围内还没有同时诊断为HCSD和钴胺素C缺乏症的病例。本报告详细介绍了一名11岁零9个月大的中国女性患者,其症状包括呕吐、意识改变和皮疹。实验室评估显示存在代谢性酸中毒、甲基丙二酸尿和同型半胱氨酸尿。遗传分析显示MMACHC基因突变:c.482G和gt;A (p.R161Q)和c.567dup (p.r 190yfs * 13)。此外,两种先前未报道的HLCS基因突变,c.1922G >;T (p.G641V)和c.1754C >;T (p.P585L),鉴定。她被诊断为全羧化酶合成酶缺乏和钴胺素C缺乏。儿童在接受羟钴胺素、甜菜碱和生物素治疗后表现出明显的改善。结论报告1例青少年发病HCSD合并钴胺素C缺乏症。用羟钴胺素、甜菜碱和生物素治疗是有效的。据报道,导致HCSD的HLCS基因中有两个新的突变,为突变筛查提供了更广泛的基础,并为类似疾病的诊断和治疗提供了见解。

Objective

This study investigates the link between blood manganese (Mn) levels and non-alcoholic fatty liver disease (NAFLD) in a U.S. adult population.

Background

The role of manganese in NAFLD remains poorly understood. However, the NHANES database offers valuable data on blood manganese levels and metabolic status for 6278 subjects in the United States, facilitating the study of this relationship.

Methods

To investigate the relationship between blood manganese (Mn) levels and NAFLD, we conducted a t-test to compare Mn levels between participants with and without NAFLD. Participants were categorized into quartiles based on their blood Mn levels. We then employed multiple logistic regression analysis and sensitivity analyses to further examine the Mn-NAFLD relationship.

Results

The NAFLD group had a significantly higher blood manganese level (10.0 ± 3.7 μg/L, P < 0.05) than the control group. Stratifying 6278 subjects by blood manganese quartiles showed increased NAFLD odds in higher quartiles (Q2-Q4) vs. Q1 (ORs: 1.49, 1.37, 1.49). The Mn-NAFLD relationship followed an inverted L-shaped curve, peaking at 8.52 μg/L.

Conclusions

Elevated levels of manganese in the blood have been shown to be associated with an increase in the risk of NAFLD, and blood manganese values can be utilized as a marker for assessing NAFLD.
目的:本研究探讨美国成年人血锰(Mn)水平与非酒精性脂肪肝(NAFLD)之间的关系。锰在NAFLD中的作用仍然知之甚少。然而,NHANES数据库提供了美国6278名受试者的血锰水平和代谢状态的宝贵数据,促进了这种关系的研究。方法为了研究血锰(Mn)水平与NAFLD之间的关系,我们进行了t检验,比较了NAFLD患者和非NAFLD患者的Mn水平。参与者根据他们的血锰水平被分为四分位数。然后,我们采用多元逻辑回归分析和敏感性分析来进一步检验Mn-NAFLD的关系。结果NAFLD组血锰水平显著高于对照组(10.0±3.7 μg/L, P <;0.05)。按血锰四分位数对6278名受试者分层显示,高四分位数NAFLD的几率(Q2-Q4)比Q1增加(or: 1.49, 1.37, 1.49)。Mn-NAFLD呈倒L型关系,峰值为8.52 μg/L。结论血液中锰含量升高与NAFLD风险增加有关,血锰值可作为NAFLD评估指标。

Celastrol is widely recognized as one of the most potent anti-obesity agents, and its ability to promote adipocyte thermogenesis is thought to be a key mechanism. However, the precise molecular targets through which celastrol modulates thermogenesis in human adipocytes remain unclear. In this study, we synthesized a celastrol-based small molecular probe and employed a combination of photoaffinity labeling (PAL), click chemistry, and Surface Plasmon Resonance (SPR) to identify its direct binding targets. Our results reveal that celastrol directly interacts with creatine kinase B-type (CKB), leading to an increase in CKB protein stability. This suggests that celastrol modulates the futile creatine cycle within human brown adipocytes, thereby contributing to thermogenesis. Collectively, our findings provide new insights into the molecular mechanisms by which celastrol promotes thermogenesis in human brown adipocytes. Notably, we demonstrated that celastrol targets CKB-mediated futile creatine cycle for the first time. These findings not only deepen our understanding of celastrol's role in weight loss but also provides a potential strategy for obesity treatment.
Celastrol被广泛认为是最有效的抗肥胖药物之一,其促进脂肪细胞产热的能力被认为是一个关键的机制。然而,celastrol调节人体脂肪细胞产热的精确分子靶点尚不清楚。在本研究中,我们合成了一种基于celastrol的小分子探针,并结合光亲和标记(PAL)、点击化学和表面等离子体共振(SPR)来鉴定其直接结合靶点。我们的研究结果表明,雷公藤红素直接与肌酸激酶b型(CKB)相互作用,导致CKB蛋白稳定性增加。这表明,celastrol调节人体棕色脂肪细胞内无用的肌酸循环,从而促进产热。总的来说,我们的发现为雷公藤红素促进人类棕色脂肪细胞产热的分子机制提供了新的见解。值得注意的是,我们首次证明了celastrol靶向ckb介导的无效肌酸循环。这些发现不仅加深了我们对celastrol在减肥中的作用的理解,而且为肥胖治疗提供了潜在的策略。

Aims

To compare the performance of newer insulin resistance (IR) indices, triglyceride glucose index (TyG) and metabolic score for IR (METS-IR), with previous markers HOMA-IR and McAuley-IR, and assess the impact of one-year of vitamin D supplementation, at two doses, on these indices in overweight, elderly individuals.

Methods

Exploratory analyses from a double-blind, multicenter randomized controlled trial involved overweight elderly participants with baseline serum 25-hydroxyvitamin D [25(OH)D] levels of 10–30 ng/ml (clinicaltrial.gov: NCT01315366). Participants received 1000 mg calcium citrate/day and vitamin D supplementation at a low-dose of 600 IU/day, or high-dose of 3750 IU/day.

Results

221 participants received low or high-dose vitamin D supplementation. Mean age was 71 ± 5 years, BMI 30 ± 4 kg/m2, 25(OH)D 20 ± 7 ng/ml, with 55 % female and 69 % with prediabetes. There were no significant baseline differences except for HDL levels (p = 0.04). TyG was notably increased in the high-dose group (p = 0.02). Mixed linear model analysis showed a greater increase in serum 25(OH)D in the high-dose group compared to the low-dose, with decreases in PTH, cholesterol, and LDL independent of dose. TyG and METS-IR did not differ by dose, time, or dose∗time interaction. Subgroup analyses by sex, baseline 25(OH)D cut-off, and glucose tolerance status were null. FokI polymorphism showed a significantly greater METS-IR in the high-dose arm, disappeared after adjusting for fat mass. McAuley-IR was the best IR index compared to TyG and METS-IR, both at baseline and 12 months.

Conclusions

Vitamin D supplementation at 3750 IU/d over one-year did not improve IR markers, including TyG and METS-IR.
目的比较较新的胰岛素抵抗(IR)指数、甘油三酯葡萄糖指数(TyG)和IR代谢评分(METS-IR)与先前的HOMA-IR和McAuley-IR指标的表现,并评估1年两剂量维生素D补充对超重老年人这些指标的影响。方法:一项双盲、多中心随机对照试验纳入了基线血清25-羟基维生素D [25(OH)D]水平为10-30 ng/ml的超重老年人(clinicaltrial.gov: NCT01315366)。参与者每天服用1000毫克柠檬酸钙和维生素D补充剂,低剂量为600 IU/天,高剂量为3750 IU/天。结果221名参与者接受了低剂量或高剂量的维生素D补充。平均年龄71±5岁,BMI 30±4 kg/m2, 25(OH)D 20±7 ng/ml,女性55%,糖尿病前期69%。除HDL水平外,两组间无显著基线差异(p = 0.04)。高剂量组TyG明显升高(p = 0.02)。混合线性模型分析显示,与低剂量组相比,高剂量组血清25(OH)D的增加更大,PTH、胆固醇和LDL的降低与剂量无关。TyG和METS-IR在剂量、时间或剂量*时间相互作用方面没有差异。按性别、基线25(OH)D临界值和葡萄糖耐量状态进行的亚组分析无效。FokI多态性在高剂量组显示met - ir显著增加,在调整脂肪量后消失。在基线和12个月时,与TyG和METS-IR相比,McAuley-IR是最好的IR指数。结论补充3750 IU/ D超过一年的维生素D并没有改善IR标志物,包括TyG和METS-IR。

Aims

Remote monitoring can support patients with Type II diabetes. Still, evidence for improved glucose outcomes in broad community practice patients is extremely limited. We examined remote glucose monitoring in newly diagnosed patients with diabetes to identify its impact on diabetes outcomes.

Methods

In a retrospective cohort study of all adults (age 18–75) with newly diagnosed Type II diabetes February 2020–December 2021 in a large integrated health system, we compared HbA1c (units: percentage, %) outcomes in remote monitoring users to non-users in their first year with diabetes, using propensity-weighted analyses.

Results

Among 35,958 patients, patients age 45+ (vs. age 18–34), who were Asian/Pacific Islander or Hispanic (compared to White), living in more deprived neighborhoods, not using the patient portal, or with baseline HbA1c ≤ 8 were significantly (p < 0.001) less likely to use remote glucose monitoring. After adjustment, remote monitoring use was associated with a 23 % (95 % CI: 17–29 %) higher rate of reaching the HbA1c ≤ 8 % (vs. non-users). In patients starting with HbA1c > 8, remote glucose monitoring use was associated with 0.93 % greater absolute improvement in HbA1c value (vs. non-users, p < 0.05).

Conclusions

Remote glucose monitoring was associated with improved HbA1c among newly diagnosed patients with Type II diabetes.
目的远程监测可以为II型糖尿病患者提供支持。然而,在广泛的社区实践患者中改善血糖结果的证据非常有限。我们检查了新诊断的糖尿病患者的远程血糖监测,以确定其对糖尿病结局的影响。方法在一项回顾性队列研究中,研究人员对2020年2月至2021年12月在一个大型综合卫生系统中新诊断为II型糖尿病的所有成年人(18-75岁)进行了研究,使用倾向加权分析,比较了远程监测用户与非用户在糖尿病第一年的HbA1c(单位:百分比,%)结果。结果在35,958例患者中,年龄45岁以上(vs.年龄18-34岁)、亚裔/太平洋岛民或西班牙裔(与白人相比)、生活在更贫困的社区、未使用患者门户网站或基线HbA1c≤8的患者显著(p <;0.001)不太可能使用远程血糖监测。调整后,远程监测的使用与达到HbA1c≤8%的高23% (95% CI: 17 - 29%)相关(与非用户相比)。从HbA1c开始的患者;8、使用远程血糖监测与HbA1c值的绝对改善相关(与未使用者相比,p <;0.05)。结论远程血糖监测与新诊断II型糖尿病患者HbA1c改善相关。
