Remodelling the inguinal adipose sensory system to switch on the furnace: Electroacupuncture stimulation induces brown adipose thermogenesis.

Brown and white adipose tissue mediate thermogenesis through the thermogenetic centre of the brain, but safe methods for activating thermogensis and knowledge of the associated molecular mechanisms are lacking. We investigated body surface electroacupuncture stimulation (ES) at ST25 (targeted at the abdomen) induction of brown adipose thermogenesis and the neural mechanism of this process. Inguinal white adipose tissue (iWAT) and interscapular brown adipose tissue (iBAT) were collected and the thermogenic protein expression levels were measured to evaluate iBAT thermogenesis capacity. The thermogenic centre activating region and sympathetic outflow were evaluated based on neural electrical activity and c-fos expression levels. iWAT sensory axon plasticity was analysed with whole-mount adipose tissue imaging. ES activated the sympathetic nerves in iBAT and the c-fos-positive cells induced sympathetic outflow activation to the iBAT from the medial preoptic area (MPA), the dorsomedial hypothalamus (DM) and the raphe pallidus nucleus (RPA). iWAT denervation mice exhibited decreased c-fos-positive cells in the DM and RPA, and lower recombinant uncoupling orotein 1 peroxisome proliferator-activated receptor, ß3-adrenergic receptor, and tyrosine hydroxylase expression. Remodelling the iWAT sensory axons recovered the signal from the MPA to the RPA and induced iBAT thermogenesis. The sympathetic denervation attenuated sensory nerve density. ES induced sympathetic outflow from the thermogenetic centres to iBAT, which mediated thermogenesis. iWAT sensory axon remodelling induced the MPA-DM-RPA-iBAT thermogenesis pathway.

Neuregulin4-ErbB4 signalling pathway is driven by electroacupuncture stimulation to remodel brown adipose tissue innervation.

AIM: To show that electroacupuncture stimulation (ES) remodels sympathetic innervation in brown adipose tissue (BAT) via the bone morphogenic protein 8B (BMP8B)-neuregulin 4 (NRG4)-ErbB4 axis, with somatotopic dependence. MATERIALS AND METHODS: We established a high-fat diet (HFD) model with C57BL/6J mice to measure the thermogenesis and metabolism of BAT. In addition, the sympathetic nerve activity (SNA) was measured with the electrophysiological technique, and the immunostaining of c-Fos was used to detect the central nervous system sources of sympathetic outflows. Finally, the key role of the BMP8B-NRG4-ErbB4 axis was verified by peripheral specific antagonism of ErbB4. RESULTS: ES at the forelimb and abdomen regions significantly up-regulate SNA, whereas ES at the hindlimb region has a limited regulatory effect on SNA but still partially restores HFD-induced BAT dysfunction. Mechanistically, ES at the forelimb and abdomen regions driving catecholaminergic signals in brown adipocytes depends on neural activities projected from the ventromedial nucleus of the hypothalamus (VMH) to the spinal cord intermediolateral column (IML). Notably, the peripheral suppression of ErbB4 in BAT inhibits the thermogenesis and metabolic function of BAT, as well as significantly hindering the SNA activation and metabolic benefits induced by ES. CONCLUSION: These results suggest that ES appears to be an effective approach for remodeling sympathetic innervation in BAT, which is closely related to neuronal activity in the VMH and the NRG4-ErbB4 signaling pathway.

Electroacupuncture alleviates intrauterine adhesion through regulating autophagy in rats.

Autophagy is a well-conserved metabolic system that maintains homeostasis by relying on lysosomal breakdown. The endometrium of patients with intrauterine adhesion (IUA) and an animal model exhibits impaired autophagy. Autophagy is negatively correlated with inflammation. Activation of autophagy can inhibit the inflammatory response, while defects in autophagy will activate the inflammatory response. Here, we studied whether electroacupuncture (EA) inhibits inflammation and promotes endometrial injury repair by activating endometrial autophagy. The IUA animal model was established by mechanical injury plus lipopolysaccharide infection. EA stimulation was applied to the acupoints Guanyuan (CV4), bilateral Sanyinjiao (SP6), and Zusanli (ST36). The results indicated that EA could improve endometrial morphology, attenuate endometrial fibers, and enhance endometrial receptivity in the rat. EA could increase the autophagosomes of endometrial epithelial cells, increase the levels of LC3 and Beclin1, and decrease the level of p62. Additionally, EA may also suppress the nuclear factor kappa-B (NF-κB) signaling pathway and reduce the release of inflammatory factors. Additionally, the effect of EA was comparable to that of the autophagy agonist rapamycin, and the autophagy inhibitor 3-methyladenine reversed the therapeutic effect of EA. Therefore, we assume that EA may facilitate endometrial healing by activating autophagy and reducing NF-κB signal pathway-mediated inflammation.

Neuromechanical Dimorphism of Hypoglycemic Effect of Electroacupuncture.

INTRODUCTION: Electroacupuncture (EA) has a favorable impact on blood glucose stability. Blood glucose homeostasis is linked to sexual dimorphism. The majority of research has, however, focused on male participants, and sex differences have not been adequately taken into account. METHODS: Here, we investigated how EA intervention affected pancreatic metabolic stress and explored if there were any sex-related changes in the maintenance of pancreatic function following intraperitoneal injection of a 10 g/kg glucose solution. RESULTS: The transient receptor potential vanilloid 1 (TRPV1) calcitonin gene-related peptide (CGRP)-ß cell pathway of the male pancreas is vital to maintain glucose metabolism in mice. In contrast, there is a sex bias in TRPV1, which implies that female mice have additional routes for preserving glucose homeostasis. EA is ineffective on Trpv1-/- male mice. It also revealed that TRPV1 in male mice served as a crucial mediator for the EA control of blood glucose. Meanwhile, the sympathetic marker tyrosine hydroxylase showed higher expression in the male pancreas, while the cholinergic marker choline acetyltransferase is expressed predominantly in female mice. Injecting γ-aminobutyric acid into the paraventricular nucleus of male mice caused a disruption in blood glucose and a lack of response to EA. It verified that male mice had a more pronounced sympathetic innervation of the pancreas than female mice. CONCLUSION: Our research has demonstrated that the TRPV1 sensory afferent nerve and sympathetic efferent nerve are capable of maintaining glucose homeostasis, exhibiting a distinct sexual dimorphism. Furthermore, this regulation is contingent on the EA effect.

FAPbBr3@PbBr(OH) phosphor with high stability for anti-counterfeiting application via water induction.

Organic-inorganic hybrid perovskite nanocrystals have become a very widely used as semiconductor light-emitting materials. However, perovskite nanocrystals face stability challenges, which is a key factor hindering their application. In this paper, by introducing water into the synthesis of formamidinium lead bromide (FAPbBr3) perovskite, ultra-stable FAPbBr3@PbBr(OH) fluorescent material was prepared. The photoluminescence intensity of the material after the addition of water increased 2.9 times compared with that before the addition of water. The excellent green fluorescence emission was still maintained after four cycles of wash-dry treatment. Meanwhile, it also exhibits good ultraviolet and thermal stability. The above enhanced performance of FAPbBr3nanocrystals is attributed the protection of PbBr(OH). In addition, the prepared material can be used in anti-counterfeit patterns. The anti-counterfeit patterns have good color rendering and the luminous color has a high dependence on temperature. Both of these features make it very valuable for various fluorescent anti-counterfeiting labels.

Association of stent diameter and target vessel revascularization in patients undergoing percutaneous coronary intervention: a secondary retrospective analysis based on a Chinese cohort study.

BACKGROUND: In the treatment of coronary heart disease, target vessel revascularization (TVR) has attracted increasing attention as an efficient means of percutaneous coronary intervention (PCI). The purpose of this study was to explore the association between stent diameter and TVR in patients undergoing PCI. METHODS: This was a secondary retrospective analysis involving patients with PCI with at least one stent implanted. Information was obtained from the Dryad Digital Repository. Multivariable logistic regression models, interaction analyses, subgroup analyses and piecewise linear regression models were used to evaluate the association between stent diameter and TVR. RESULTS: A total of 2522 patients were eventually enrolled in this study, of which 122 (4.8%) had undergone TVR. Significant positive associations were observed between stent diameter and TVR (continuous: odds ratio [OR] 0.485, 95% confidence interval [CI] 0.305-0.773, P = 0.002; categorical variable: T2 vs. T1, OR 0.541, 95% CI 0.348-0.843; T3 vs. T1, OR 0.520, 95% CI 0.334-0.809; P for trend = 0.005). The association remained stable in the fully adjusted model (continuous: OR 0.526, 95% CI 0.306-0.902, P = 0.020; categorical variable: T2 vs. T1, OR 0.510, 95% CI 0.310-0.839; T3 vs. T1, OR 0.585, 95% CI 0.352-0.973; P for trend = 0.042). Among the subgroups of differing clinical presentations, stent diameter was a powerful protective factor for TVR, especially in the delayed PCI group (P for interaction = 0.002). The association was highly consistent across all the other subgroups studied (all P for interaction > 0.05). In the piecewise linear regression model, the need for TVR decreased with an increase in stent diameter when this ranged between 2.5 and 2.9 mm (OR 0.01, 95% CI: 0.01-0.13, P < 0.001). CONCLUSIONS: A large stent diameter is a powerful protective factor for TVR in PCI patients, especially in the delayed PCI group. This "bigger-is-better" protective effect is remarkable in stents with diameter 2.5-2.9 mm.

Targeting aerobic glycolysis by dichloroacetate improves Newcastle disease virus-mediated viro-immunotherapy in hepatocellular carcinoma.

BACKGROUND: Oncolytic viro-immunotherapy holds promise for cancer treatment. While immune activation can be robustly triggered by oncolytic viruses, negative feedback is often upregulated in the tumour microenvironment (TME). Lactate accumulation, signal transducer and activator of transcription 3 (STAT3) activation, indoleamine 2,3-dioxygenase 1 (IDO1) expression, and myeloid-derived suppressor cell (MDSC) infiltration coordinate to shape the immunosuppressive TME. METHODS: Representative hepatocellular carcinoma (HCC) cell lines and HCC-bearing mice were treated with oncolytic Newcastle disease virus (NDV), alone or in combination with dichloroacetate (DCA, a pyruvate dehydrogenase kinase (PDK) inhibitor). RESULTS: We found that infection with oncolytic NDV led to significant induction of the aforementioned suppressive factors. Interestingly, DCA significantly reduced lactate release, STAT3 activation, IDO1 upregulation, and MDSC infiltration in NDV-treated HCC. Consequently, DCA significantly enhanced the antitumour immune responses, leading to improved antitumour efficacy and prolonged survival in mouse models of ascitic and subcutaneous HCC. Furthermore, DCA increased NDV replication in a PDK-1-dependent manner in HCC. CONCLUSIONS: Targeting aerobic glycolysis by DCA improves NDV-mediated viro-immunotherapy in HCC by mitigating immune negative feedback and promoting viral replication. These findings provide a rationale for targeting reprogrammed metabolism together with oncolytic virus-mediated viro-immunotherapy for HCC treatment.

Electrophysiological characteristics and clinical values of left bundle branch current of injury in left bundle branch pacing.

BACKGROUND: Left bundle branch pacing (LBBP) is emerging as a novel option for physiological ventricular pacing. The impact of current of injury (COI) at left bundle branch (LBB) has not been previously evaluated. METHODS: Consecutive patients with QRS duration less than 120 milliseconds referred for LBBP in whom LBB potentials were recorded were included from August 2018 to March 2019. We recorded LBB COI during LBBP and assessed its impact on the pacing parameters and complications during implantation and at short term follow-up. RESULTS: A total of 115 patients with an identifiable LBB potential at implant were included. LBB COI was confirmed in 77 (67.0%) of these patients. Three types of LBB COI were observed. LBB was captured in all patients at a pacing threshold less than 1.5 V/0.5 ms in COI(+) patients, while present in only 29 patients without an LBB COI(-) (100% vs 76.3%; P < .001). There was no significant difference between COI(+) and COI(-) patients in LBB bundle capture threshold (0.64 ± 0.24 vs 0.74 ± 0.26 V/0.5 ms). Selective LBBP was more common in COI(+) group than COI(-) group (54.5% vs 0%; P < .001). Pacing parameters were stable and no lead perforation or dislodgements were observed during follow-up. CONCLUSIONS: LBB COI is commonly observed during LBBP in cases with an identifiable LBB potential and can be associated with a low LBB capture threshold and demonstrable selective capture of the LBB acutely and during follow-up. A COI does not preclude safe and stable LBBP pacing.

Long-term performance and risk factors analysis after permanent His-bundle pacing and atrioventricular node ablation in patients with atrial fibrillation and heart failure.

AIMS: His-bundle pacing (HBP) combined with atrioventricular node (AVN) ablation has been demonstrated to be effective in patients with atrial fibrillation (AF) and heart failure (HF) during medium-term follow-up and there are limited data on the risk analysis of adverse prognosis in this population. In this study, we aimed to evaluate the long-term performance of HBP following AVN ablation in AF and HF. METHODS AND RESULTS: From August 2012 to December 2017, consecutive AF patients with HF and narrow QRS who underwent AVN ablation and HBP were enrolled. The clinical and echocardiographic data, pacing parameters, all-cause mortality, and heart failure hospitalization (HFH) were tracked. A total of 94 patients were enrolled (age 70.1 ± 10.5 years; male 57.4%). Acute HBP were achieved in 89 (94.7%) patients with successful permanent HBP combined with AVN ablation in 81 (86.2%) patients. Left ventricular ejection fraction (LVEF) improved from 44.9 ± 14.9% at baseline to 57.6 ± 12.5% during a median follow-up of 3.0 (IQR: 2.0-4.4) years (P < 0.001). Heart failure hospitalization or all-cause mortality occurred in 21 (25.9%) patients. The LVEF ≤ 40%, pulmonary artery systolic pressure (PASP) ≥40 mmHg, or serum creatinine (Scr) ≥97 µmol/L at baseline was significantly associated with higher composite endpoint of HFH or death (P < 0.05). The His capture threshold was 1.0 ± 0.7 V/0.5 ms at implant and remained stable during follow-up. CONCLUSION: His-bundle pacing combined with AVN ablation was effective in patients with AF and drug-refectory HF. High PASP, high Scr, or low LVEF at baseline was independent predictors of composite endpoint of all-cause mortality or HFH.

Risk scores for predicting dysphagia in critically ill patients after cardiac surgery.

BACKGROUND: This study aimed at developing and validating a scoring model to stratify critically ill patients after cardiac surgery based on risk for dysphagia, a common but often neglected complication. METHODS: Data were prospectively collected and analyzed from January 2016 to June 2017 from 395 consecutive post cardiac surgery patients at the cardiac care unit (CCU) at a single center; 103 (26.1%) developed dysphagia. Univariate and multivariate logistic analyses were used to identify independent predictors for dysphagia. The survival nomogram was developed on the basis of a multivariable Cox model, which allowed us to obtain survival probability estimations. The predictive performance of the nomogram was verified for discrimination and calibration. Areas under receiver operating characteristic curve analysis were used to illustrate and evaluate the diagnostic performance of the novel model. RESULTS: The final novel scoring model, named SSG-OD, consists of three independent factors: gastric intubation (OR = 1.024, 95% CI 1.015-1.033), sedative drug use duration (OR = 1.031, 95% CI 1.001-1.063) and stroke or not (OR = 6.182, 95% CI 3.028-12.617). SSG-OD identified patients at risk for dysphagia with sensitivity of 68.5% and specificity of 89.0% (OR = 0.833, 95% CI: 0.782-0.884). The positive and negative likelihood ratios were 6.22 and 0.35. CONCLUSIONS: The novel SSG-OD scoring system to risk stratify CCU patients for dysphagia is an easy-to-use bedside prognostication aid with good predictive performance and the potential to reduce aspiration incidence and accelerate recovery.

[Quantitative study on the acupoint effects based on complex network analysis: with the examples of the textbook networks formed by Chinese Acupuncture and Moxibustion Therapy and Practical Acupuncture and Moxibustion].

By extracting the acupoint names and their main indications from cases in Chinese Acupuncture and Moxibustion Therapy and Practical Acupuncture and Moxibustion, the acupoints and their main indications are represented in a reduced dimension, establishing an "acupoint-indication" linkage. Using complex network detection results (node degree values), the specificity of acupoints was assessed. The small-world characteristics of the "acupoint-indication" network are utilized to analyze the consistency of acupoint selection in acupuncture prescriptions and strategies to avoid redundant acupoints. The results show that the "acupoint-indication" network formed by both texts exhibited an approximate "long-tail" distribution, with a large number of node degree values concentrated between 0 and 4 000, while a few nodes have degree values exceeding 10 000. There are significant differences in the number and distribution of nodes with degree values> 10 000 between the two texts. Chinese Acupuncture and Moxibustion Therapy includes 11 acupoints with multiple edges across the body, whereas Practical Acupuncture and Moxibustion contains only 2 such acupoints, located in the lower limbs. Clinically, some acupoints have a broad therapeutic effect and appear in numerous prescriptions. The division of acupoints based on node degree values can coarsely evaluate the body region specificity of acupoints' regulatory effects. The "acupoint-indication" network of Chinese Acupuncture and Moxibustion Therapy has a higher number of edges than that of Practical Acupuncture and Moxibustion, which might be related to the different historical contexts of the two texts. In the future, diagnostic and therapeutic patterns with historical continuity can be utilized to optimize acupuncture prescriptions.

Gut-targeted therapies for type 2 diabetes mellitus: A review.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by hyperglycemia and insulin resistance. The global prevalence of T2DM has reached epidemic proportions, affecting approximately 463 million adults worldwide in 2019. Current treatments for T2DM include lifestyle modifications, oral antidiabetic agents, and insulin therapy. However, these therapies may carry side effects and fail to achieve optimal glycemic control in some patients. Therefore, there is a growing interest in the role of gut microbiota and more gut-targeted therapies in the management of T2DM. The gut microbiota, which refers to the community of microorganisms that inhabit the human gut, has been shown to play a crucial role in the regulation of glucose metabolism and insulin sensitivity. Alterations in gut microbiota composition and diversity have been observed in T2DM patients, with a reduction in beneficial bacteria and an increase in pathogenic bacteria. This dysbiosis may contribute to the pathogenesis of the disease by promoting inflammation and impairing gut barrier function. Several gut-targeted therapies have been developed to modulate the gut microbiota and improve glycemic control in T2DM. One potential approach is the use of probiotics, which are live microorganisms that confer health benefits to the host when administered in adequate amounts. Several randomized controlled trials have demonstrated that certain probiotics, such as Lactobacillus and Bifidobacterium species, can improve glycemic control and insulin sensitivity in T2DM patients. Mechanisms may include the production of short-chain fatty acids, the improvement of gut barrier function, and the reduction of inflammation. Another gut-targeted therapy is fecal microbiota transplantation (FMT), which involves the transfer of fecal material from a healthy donor to a recipient. FMT has been used successfully in the treatment of Clostridioides difficile infection and is now being investigated as a potential therapy for T2DM. A recent randomized controlled trial showed that FMT from lean donors improved glucose metabolism and insulin sensitivity in T2DM patients with obesity. However, FMT carries potential risks, including transmission of infectious agents and alterations in the recipient's gut microbiota that may be undesirable. In addition to probiotics and FMT, other gut-targeted therapies are being investigated for the management of T2DM, such as prebiotics, synbiotics, and postbiotics. Prebiotics are dietary fibers that promote the growth of beneficial gut bacteria, while synbiotics combine probiotics and prebiotics. Postbiotics refer to the metabolic products of probiotics that may have beneficial effects on the host. The NIH SPARC program, or the Stimulating Peripheral Activity to Relieve Conditions, is a research initiative aimed at developing new therapies for a variety of health conditions, including T2DM. The SPARC program focuses on using electrical stimulation to activate peripheral nerves and organs, in order to regulate glucose levels in the body. The goal of this approach is to develop targeted, non-invasive therapies that can help patients better manage their diabetes. One promising area of research within the SPARC program is the use of electrical stimulation to activate the vagus nerve, which plays an important role in regulating glucose metabolism. Studies have shown that vagus nerve stimulation can improve insulin sensitivity and lower blood glucose levels in patients with T2DM. Gut-targeted therapies, such as probiotics and FMT, have shown potential for improving glycemic control and insulin sensitivity in T2DM patients. However, further research is needed to determine the optimal dose, duration, and safety of these therapies.

Immune metabolic mechanisms of acupuncture in improving glycolipid metabolic disorders explored through pancreatic adipose tissue. / ä»Žèƒ°è ºè„‚è‚ªç»„ç»‡æŽ¢è®¨é’ˆåˆºæ”¹å–„ç³–è„‚ä»£è°¢ç— çš„å ç–«ä»£è°¢æœºåˆ¶.

Pancreatic adipose tissue serves as a crucial structural basis for the development of glycolipid metabolic disorders. Understanding the mechanisms underlying pancreatic adipose tissue infiltration and regulatory strategies is essential for early intervention in glycolipid metabolic disorders. Pancreatic adipose tissue functions as a significant medium linking systemic immune metabolism, while the pancreatic vascular system emerges as a novel target for sensing pancreatic immune responses and maintaining the body's energy homeostasis, collectively participating in the development of glycolipid metabolic disorders. Acupuncture possesses potential effects in modulating the interaction between resident macrophages and adipocytes in the pancreas, leading to the reversible reduction of excessive pancreatic adipose accumulation, with its action being vascular-dependent.

Education and training of acupuncture-moxibustion professionals from the perspective of medicine-engineering interdiscipline: case analysis of China's higher education reform and transformation under the background of "emerging medical education". / åŒ»å·¥ç»“åˆè§†è§’ä¸‹é’ˆç¸ä¸“ä¸šäººæ‰çš„æ•™è‚²ä¸ŽåŸ¹å ».

A sustainable training system for acupuncture-moxibustion and tuina professionals, integrating "medicine, industry, education and research" is established, under the main framework of the medicine-engineering interdiscipline, and with the consideration of the issues of medicine, the application of engineering technology, the thinking approaches of sciences, and the collaboration of business studies. It is the potential power to support the development of traditional medicine. Through analyzing the difficulties of the medicine-engineering interdiscipline of acupuncture specialty, and in association with the experiences of the early-stage development of the collaboration between medicine and engineering, the paper presents the cases of China's higher education reform and transformation under the background of "emerging medical education" so as to explore a replicable personnel training mode.

Electroacupuncture stimulation ameliorates cognitive impairment induced by long-term high-fat diet by regulating microglial BDNF.

Long-term high-fat diet (HFD) in adolescents leads to impaired hippocampal function and increases the risk of cognitive impairment. Studies have shown that HFD activates hippocampal microglia and induces hippocampal inflammation, which is an important factor for cognitive impairment. Electroacupuncture stimulation (ES), a nerve stimulation therapy, is anti-inflammatory. This study explored its therapeutic potential and mechanism of action in obesity-related cognitive impairment. 4-week-old C57 mice were given either normal or HFD for 22 weeks. At 19 weeks, some of the HFD mice were treated with ES and nigericin sodium salt. The cognitive behavior was assessed through Morris water maze test at 23 weeks. Western blotting was used to detect the expression levels of pro-inflammatory molecules IL-1ß and IL-1R, synaptic plasticity related proteins synaptophysin and Postsynaptic Density-95 (PSD-95), and apoptotic molecules (Caspase-3 and Bcl-2), in the hippocampus. The number, morphology, and status of microglia, along with the brain-derived neurotrophic factor（BDNF） content, were analyzed using immunofluorescence. ES treatment improved cognitive deficits in HFD model mice, and decreased the expressions of microglial activation marker, CD68, and microglial BDNF. Inhibition of proinflammatory cytokine, IL-1ß, and IL-1R promoted PSD-95 and synaptophysin expressions. Peripheral NLRP3 inflammasome agonist injections exacerbated the cognitive deficits in HFD mice and promoted the expressions of IL-1ß and IL-1R in the hippocampus. The microglia showed obvious morphological damage and apoptosis. Collectively, our findings suggest that ES inhibits inflammation, regulates microglial BDNF, and causes remodeling of hippocampal function in mice to counteract obesity-like induced cognitive impairment. Overexcitation of peripheral inflammasome complexes induces hippocampal microglia apoptosis, which hinders the effects of ES.

Antioxidant Minerals Modified the Association between Iron and Type 2 Diabetes in a Chinese Population.

Inconsistent findings exist regarding the relationship between heme iron intake and type 2 diabetes (T2D) among Western and Eastern populations. Easterners tend to consume a plant-based diet which is abundant in antioxidant minerals. To examine the hypothesis that antioxidant mineral may modify the relationship between iron and T2D, we performed a case-control study by measuring the serum mineral levels in 2198 Chinese subjects. A total of 2113 T2D patients and 2458 controls were invited; 502 T2D patients and 1696 controls were finally analyzed. In the total population, high serum iron showed a positive association with T2D odds (odds ratio [OR] = 1.27 [1.04, 1.55]); high magnesium (OR = 0.18 [0.14, 0.22]), copper (OR = 0.27 [0.21, 0.33]), zinc (OR = 0.37 [0.30, 0.46]), chromium (OR = 0.61 [0.50, 0.74]), or selenium concentrations (OR = 0.39 [0.31, 0.48]) were inversely associated with T2D odds. In contrast, in individuals with higher magnesium (>2673.2 µg/dL), zinc (>136.7 µg/dL), copper (>132.1 µg/dL), chromium (>14.0 µg/dL), or selenium concentrations (>16.8 µg/dL), serum iron displayed no association with T2D (p > 0.05). Serum copper and magnesium were significant modifiers of the association between iron and T2D in individuals with different physiological status (p < 0.05). Our findings support the idea that consuming a diet rich in antioxidant minerals is an effective approach for preventing T2D.

In vitro comparative study of multimodal imaging nano-assembled microspheres with two clinical drug-eluting beads loaded with doxorubicin.

DC Beads and CalliSpheres are commonly used microspheres in clinical transcatheter arterial chemoembolization, but these microspheres cannot be visualized by themselves. Therefore, in our previous study, we developed multimodal imaging nano-assembled microspheres (NAMs), which are visualized under CT/MR and the location of embolic microspheres can be determined during postoperative review, facilitating the evaluation of embolic areas and guiding subsequent treatment. Moreover, the NAMs can be carried with positively and negatively charged drugs, increasing the choice of drugs. Systematic comparative analysis of the pharmacokinetics of NAMs with commercially available DC Bead and CalliSpheres microspheres is important for evaluating the clinical application of NAMs. In our study, we compared the similarities and differences between NAMs and two drug-eluting beads (DEBs) in respect to drug loading capacity, drug release profiles, diameter variation and morphological characteristics. The results indicate that NAMs had good drug delivery and release characteristics as well as DC Bead and CalliSpheres in vitro experimental stage. Therefore, NAMs have a good application prospect in transcatheter arterial chemoembolization treatment of hepatocellular carcinoma.

Biophilic Design as an Important Bridge for Sustainable Interaction between Humans and the Environment: Based on Practice in Chinese Healthcare Space.

Since the COVID-19 epidemic, there has been an increased need for well-being and sustainable development, making biophilic design in hospital environments even more significant. However, after investigation, it was found that in many countries including China, the biophilic design of some hospitals is seriously absent, while other parts have the integration of biophilic design, but the standardization and recognition are not high. By restoring the interaction between buildings and nature, biophilic design improves the quality of environments and the health of users. The basic theoretical framework of environmental psychology is followed in this research. The health promotion mechanism, applicable natural features, and relative health advantages of hospital space and environment biophilic design are first investigated. Furthermore, according to the current status of biophilic design applications in the 12 hospitals that have the closest interaction between people and the environment. Combined with the professional and functional requirements of the healthcare spaces and the users' special demands, we propose appropriate update design methods. The goal of this study was to present ideas for healthy and efficient space environment design and to inspire sustainable environmental design for future healthcare environments.
