Highly Efficient and Selective Light-Driven Dry Reforming of Methane by a Carbon Exchange Mechanism.

Dry reforming of methane (DRM) is a promising technique for converting greenhouse gases (namely, CH4 and CO2) into syngas. However, traditional thermocatalytic processes require high temperatures and suffer from low selectivity and coke-induced instability. Here, we report high-entropy alloys loaded on SrTiO3 as highly efficient and coke-resistant catalysts for light-driven DRM without a secondary source of heating. This process involves carbon exchange between reactants (i.e., CO2 and CH4) and oxygen exchange between CO2 and the lattice oxygen of supports, during which CO and H2 are gradually produced and released. Such a mechanism deeply suppresses the undesired side reactions such as reverse water-gas shift reaction and methane deep dissociation. Impressively, the optimized CoNiRuRhPd/SrTiO3 catalyst achieves ultrahigh activity (15.6/16.0 mol gmetal-1 h-1 for H2/CO production), long-term stability (∼150 h), and remarkable selectivity (∼0.96). This work opens a new avenue for future energy-efficient industrial applications.

Bridging molecular photosensitizer and catalyst on carbon nanotubes toward enhanced selectivity and durability for CO2 photoreduction.

Homogenous molecular photocatalysts for CO2 reduction, especially metal complex-based photosensitizer‒catalyst assemblages, have been attracting extensive research interests due to their efficiency and customizability. However, their low durability and recyclability limit practical applications. In this work, we immobilized the catalysts of metal terpyridyl complexes and the photosensitizer of [Ru(bpy)3]Cl2 onto the surface of carbon nanotubes through covalent bonds and electrostatic interactions, respectively, transforming the homogeneous system into a heterogeneous one. Our characterizations prove that these metal complexes are well dispersed on CNTs with a high loading (ca. 12 wt.%). Photocatalytic measurements reveal that catalytic activity is remarkably enhanced when the molecular catalysts are anchored, which is three times higher than that of homogeneous molecular catalysts. Moreover, when the photosensitizer of [Ru(bpy)3]Cl2 is immobilized, the side reaction of hydrogen evolution is completely suppressed and the selectivity for CO production reaches 100%, with its durability also significantly improved. This work provides an effective pathway for constructing heterogeneous photocatalysts based on rational assembly of efficient molecular photosensitizers and catalysts.

Tailoring Second Coordination Sphere for Tunable Solid-Liquid Interfacial Charge Transfer toward Enhanced Photoelectrochemical H2 Production.

The recombination of photogenerated charge carriers severely limits the performance of photoelectrochemical (PEC) H2 production. Here, we demonstrate that this limitation can be overcome by optimizing the charge transfer dynamics at the solid-liquid interface via molecular catalyst design. Specifically, the surface of a p-Si photocathode is modulated using molecular catalysts with different metal atoms and organic ligands to improve H2 production performance. Co(pda-SO3H)2 is identified as an efficient and durable catalyst for H2 production through the rational design of metal centers and first/second coordination spheres. The modulation with Co(pda-SO3H)2, which contains an electron-withdrawing -SO3H group in the second coordination sphere, elevates the flat-band potential of the polished p-Si photocathode and nanoporous p-Si photocathode by 81 mV and 124 mV, respectively, leading to the maximized energy band bending and the minimized interfacial carrier transport resistance. Consequently, both the two photocathodes achieve the Faradaic efficiency of more than 95 % for H2 production, which is well maintained during 18 h and 21 h reaction, respectively. This work highlights that the band-edge engineering by molecular catalysts could be an important design consideration for semiconductor-catalyst hybrids toward PEC H2 production.

Clinical impact of hepatic steatosis on chronic hepatitis B patients in Asia: A systematic review and meta-analysis.

Chronic hepatitis B (CHB) and hepatic steatosis (HS) are two prevalent chronic liver diseases in Asia. The incidence of CHB combined with HS is increasing due to the rising obesity rates. However, the impact of HS on CHB remains a topic of debate. Hereby, this meta-analysis aims to examine the effect of HS on Asian patients with CHB. Searches were conducted on four databases to identify articles published from 2005 to 2023. The random-effects or fixed-effects model was used to calculate pooled odds ratios (ORs), weighted mean difference (WMD), and confidence intervals (CIs) for the included articles. Of the 15,959 records screened, 88 studies were included in the analysis of HS prevalence in Asian CHB patients with a prevalence of 36.5% (95% CI: 33.7%-39.3%). In addition, age, sex, body mass index (BMI), waist circumference (WC), alanine aminotransferase (ALT) and combined metabolic diseases have varying degrees of impact on HS in CHB patients. Furthermore, the coexistence of HS was negatively associated with the response to antiviral therapy, including hepatitis B surface antigen (HBeAg) seroconversion (OR = 0.69, 95% CI: 0.53-0.89) and ALT normalization (OR = 0.75, 95% CI: 0.61-0.92) in CHB patients after 48 weeks of treatment. Regarding disease prognosis, HS was not significantly associated with fibrosis or cirrhosis in CHB patients, while an inverse association was observed between HS and hepatocellular carcinoma (HCC) (OR = 2.93, 95% CI: 1.23-6.99). This implies that the coexistence of HS in CHB patients may exacerbate the progression of HCC, which needs to be verified by further studies.

Association of nonalcoholic fatty liver disease and growth hormone deficiency: a systematic review and meta-analysis.

An association exists between nonalcoholic fatty liver disease (NAFLD) and growth hormone (GH). Patients with growth hormone deficiency (GHD) may be more susceptible to NAFLD. The prevalence of NAFLD and nonalcoholic steatohepatitis (NASH) in GHD patients is currently unknown. Multiple databases were searched for experiments related to NAFLD (or NASH) and GHD. Screening, quality evaluation and data extraction were carried out independently by two authors. Analyses used random or fixed effects models, including NAFLD prevalence, NASH prevalence, odds ratio (OR) and 95% confidence interval (CI). We included 10 studies with a total of 782 participants. The results showed that the prevalence of NAFLD in GHD patients was 51% (95% CI: 39-63). The risk of NAFLD in GHD patients was significantly higher than that in controls (age-, sex- or body mass index-matched, without GHD) (pooled OR = 4.27, 95% CI: 1.33-13.68%, p = 0.015). The prevalence of NASH in GHD patients was 18% (95% CI: 5-31). The prevalence of NAFLD in GHD patients is significantly higher than that in the general population, especially NASH. There is a need to develop targeted strategies for the early identification, prevention, or control of NAFLD/NASH in patients with GHD.

Barriers and enabling factors in weight management of patients with nonalcoholic fatty liver disease: A qualitative study using the COM-B model of behaviour.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a global public health problem. Lifestyle modifications aimed at promoting weight loss and weight maintenance remain the current first-line treatments for NAFLD. OBJECTIVE: We aim to identify barriers and enabling factors in weight management among patients with NAFLD using the capability, opportunity, motivation, behaviour (COM-B) model of behaviour. DESIGN: This study adopted a qualitative design using semistructured interviews analysed with content analysis and the COM-B framework. SETTING AND PARTICIPANTS: Interviews were conducted with 27 patients with NAFLD who experienced successful or unsuccessful weight reduction. RESULTS: Our study included 27 participants: 15 participants with successful weight loss (successful weight loss refers to a decrease in body weight ≥7% of the initial body weight for patients with NAFLD) and 12 participants with unsuccessful weight loss. Thirty-five themes (19 barriers and 16 facilitators) were mapped onto the COM-B model as barriers and facilitators to weight management among patients with NAFLD. The key barriers were lack of time and energy, lack of awareness of weight, lack of attention to NAFLD, treating food as a reward or compensation and social entertainment. The key facilitators were having basic weight loss knowledge and skills, strong motivation, attention to NAFLD, unsuccessful weight loss experiences and positive feedback from phased success. CONCLUSION: In addition to identifying factors consistent with existing studies, this study identified factors that influence weight management in NAFLD patients, such as basic weight loss skills and rational thinking before weight loss, which were not previously reported. This has clinical implications for clinical healthcare providers and health management services for the improvement of education and support regarding lifestyle improvement and weight management in patients with NAFLD. PATIENT OR PUBLIC CONTRIBUTION: We recruited potential participants from the Bariatric Clinic, Hepatology Clinic and Physical Examination Center of hospitals between March 2021 and October 2021. Twenty-seven patients with NAFLD who had successful or unsuccessful weight loss experiences participated in the study and responded to questions on weight management.

Boosting Interfacial Charge Transfer with a Giant Internal Electric Field in a TiO2 Hollow-Sphere-Based S-Scheme Heterojunction for Efficient CO2 Photoreduction.

The construction of an S-scheme charge transfer pathway is considered to be a powerful way to inhibit charge recombination and maintain photogenerated carriers with high redox capacity to meet the kinetic requirements of the carbon dioxide (CO2) photoreduction reaction. For an S-scheme heterojunction, an internal electric field (IEF) is regarded as the main driving force for accelerating the interfacial spatial transfer of photogenerated charges. Herein, we designed a TiO2 hollow-sphere (TH)-based S-scheme heterojunction for efficient CO2 photoreduction, in which WO3 nanoparticles (WP) were applied as an oxidation semiconductor to form an intimate interfacial contact with the TH. The S-scheme charge transfer mode driven by a strong IEF for the TH/WP composite was confirmed by in situ X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. As a result, abundant photogenerated electrons with strong reducing ability would take part in the CO2 reduction reaction. The combination of surface photovoltage spectra and transient photocurrent experiments disclosed that the IEF intensity and charge separation efficiency of the fabricated TH/WP composite were nearly 16.80- and 1.42-fold higher, respectively, than those of the pure TH. Furthermore, sufficient active sites provided by the hollow-sphere structure also enhanced the kinetics of the catalytic reaction. Consequently, the optimized TH/WP composite showed a peak level of CO production of 14.20 µmol g-1 in 3 h without the addition of any sacrificial agent. This work provides insights into the kinetic studies of the S-scheme charge transfer pathway for realizing high-performance CO2 photoreduction.

Heterogeneous Single-Atom Photocatalysts: Fundamentals and Applications.

Single-atom photocatalysts have shown their compelling potential and arguably become the most active research direction in photocatalysis due to their fascinating strengths in enhancing light-harvesting, charge transfer dynamics, and surface reactions of a photocatalytic system. While numerous comprehensions about the single-atom photocatalysts have recently been amassed, advanced characterization techniques and vital theoretical studies are strengthening our understanding on these fascinating materials, allowing us to forecast their working mechanisms and applications in photocatalysis. In this review, we begin by describing the general background and definition of the single-atom photocatalysts. A brief discussion of the metal-support interactions on the single-atom photocatalysts is then provided. Thereafter, the current available characterization techniques for single-atom photocatalysts are summarized. After having some fundamental understanding on the single-atom photocatalysts, their advantages and applications in photocatalysis are discussed. Finally, we end this review with a look into the remaining challenges and future perspectives of single-atom photocatalysts. We anticipate that this review will provide some inspiration for the future discovery of the single-atom photocatalysts, manifestly stimulating the development in this emerging research area.

Precisely Tailoring Heterometallic Polyoxotitanium Clusters for the Efficient and Selective Photocatalytic Oxidation of Hydrocarbons.

Photocatalysis is a promising yet challenging approach for the selective oxidation of hydrocarbons to valuable oxygenated chemicals with O2 under mild conditions. In this work, we report an atomically precise material model to address this challenge. The key to our solution is the rational incorporation of Fe species into polyoxotitanium cluster to form a heterometallic Ti4 Fe1 cocrystal. This newly designed cocrystal cluster, which well governs the energy and charge transfer as evidenced by spectroscopic characterizations and theoretical calculations, enables the synergistic process involving C(sp3 )-H bond activation by photogenerated holes and further reactions by singlet oxygen (1 O2 ). Remarkably, the cocrystal Ti4 Fe1 cluster achieves efficient and selective oxidation of hydrocarbons (C5 to C16 ) into aldehydes and ketones with a conversion rate up to 12 860 µmol g-1 h-1 , 5 times higher than that of Fe-doped Ti3 Fe1 cluster. This work provides insights into photocatalyst design at atomic level enabling synergistic catalysis.

Photocatalytic CO2 conversion: What can we learn from conventional COx hydrogenation?

Solar-driven reduction of CO2 into fuels/feedstocks is a promising strategy for addressing energy and CO2 emission issues. Despite great research efforts, it still remains a grand challenge to achieve efficient and highly selective reduction of CO2 owing to the large bond energy of CO2 and the diversity of reduction products. In addition to the control of light harvesting and charge transfer like photocatalytic water splitting, the design of catalytically active sites is highly important to promote CO2 reduction activity and selectivity (e.g., C-C coupling). In fact, we can learn a lot from conventional CO2 hydrogenation and syngas conversion in terms of active site design. In this article, we demonstrate how to design catalytically active sites for efficient and highly selective photocatalytic reduction of CO2 by sorting out the rules from the existing research on conventional COx hydrogenation, with a focus on enhancing C[double bond, length as m-dash]O activation and C-C coupling to form value-added products. This article aims to highlight the challenges in the field of photocatalytic CO2 conversion and the connection of photocatalysis with conventional catalytic systems, providing the readers the opportunities to join the research.

Ultrastable Cu Catalyst for CO2 Electroreduction to Multicarbon Liquid Fuels by Tuning C-C Coupling with CuTi Subsurface.

Production of multicarbon (C2+ ) liquid fuels is a challenging task for electrocatalytic CO2 reduction, mainly limited by the stabilization of reaction intermediates and their subsequent C-C couplings. In this work, we report a unique catalyst, the coordinatively unsaturated Cu sites on amorphous CuTi alloy (a-CuTi@Cu) toward electrocatalytic CO2 reduction to multicarbon (C2-4 ) liquid fuels. Remarkably, the electrocatalyst yields ethanol, acetone, and n-butanol as major products with a total C2-4 faradaic efficiency of about 49 % at -0.8 V vs. reversible hydrogen electrode (RHE), which can be maintained for at least 3 months. Theoretical simulations and in situ characterization reveals that subsurface Ti atoms can increase the electron density of surface Cu sites and enhance the adsorption of *CO intermediate, which in turn reduces the energy barriers required for *CO dimerization and trimerization.

Biogeographic origin prediction of three continental populations through 42 ancestry informative SNPs.

A biogeographic estimate of a certain population can not only discern population substructure in the whole genome association study, but also provide informative clues for forensic investigations when obtained DNA genotypes do not find a match in the available forensic DNA database. In this study, 100 ancestry informative single nucleotide polymorphisms (AISNPs) were first presented to differentiate three continental ancestries (African, East Asian and European). Ultimately, forty-two AISNPs were chosen from the 100 AISNPs. Distinguishing power of the 100 and 42 AISNPs for differentiating continental populations was further evaluated with population cluster analyses. Results indicated both of AISNP sets could efficiently differentiate 11 training populations from the three continents. Further validation of 42 AISNPs in testing population set indicated these 42 AISNPs performed well for ancestry inferences of these testing individuals. Ancestry components of Uyghur group were assessed by comparing with different continental populations based on these 42 AISNPs. Results revealed that East Asian populations contributed more ancestry components to the studied Uyghur group than European populations. In conclusion, our study is expected to provide more AISNP markers and enrich extant reference database.

Ancestry informative DIP loci for dissecting genetic structure and ancestry proportions of Qinghai Tibetan and Tibet Tibetan groups.

Tibetans living in the Qing-Tibet plateau show unique genetic features since they are exposed to the high altitude environment. Accordingly, it is necessary for us to analyze genetic components of the Tibetan groups. Here, genetic structure and ancestry proportions of Tibet Tibetan and Qinghai Tibetan groups are dissected by using a previously published ancestral deletion/insertion polymorphisms (DIPs) panel. Genetic distributions of the analyzed DIPs in both Tibetan groups reveal that some DIPs show relatively balanced frequency distributions with the values ranging from 0.4 to 0.6, implying that these DIPs could be used as individual identification loci for forensic applications in both groups. Besides, the cumulative power of discrimination of the panel also reflects that the panel could serve as a valuable tool for forensic individual identifications in Tibet Tibetan and Qinghai Tibetan groups. Population genetic analyses including principal component analysis, DA genetic distances, phylogenetic tree, and genetic structure reveal that two studied Tibetan groups have closer genetic affiliations with East Asian populations. Genetic differentiation analyses of two Han populations, Xinjiang Uyghur and two Tibetan groups reveal that some DIP loci might be informative for differentiating Uyghurs from the other populations.

Interface and surface engineering of hematite photoanode for efficient solar water oxidation.

Engineering the interface and surface structures of semiconductor-based photoelectrodes for improved charge transfer dynamics and promoted water redox reaction kinetics is essential to achieve efficient photoelectrochemical (PEC) water splitting. In this work, α-Fe2O3 nanorods, successively coated with TiO2 and CoOx thin layers, were reported as the photoanode for solar-driven water oxidation. The obtained α-Fe2O3/TiO2/CoOx photoanode exhibits superior PEC performance as compared to bare α-Fe2O3, with a 3.3-time improvement in photocurrent density at 1.23 V vs reversible hydrogen electrode. This significant enhancement results from the formed heterojunction between α-Fe2O3 and TiO2 for the accelerated photogenerated charge separation and transfer as well as the passivated surface defects by the TiO2 overlayer for reduced charge recombination. Additionally, the existence of CoOx as the oxygen evolution catalyst significantly facilitates the surface reaction kinetics and thus reduces the overpotential for water oxidation. This study demonstrates a collaborative strategy of interface and surface engineering to design novel structures of α-Fe2O3 based photoanodes for highly efficient solar water oxidation.

Artificial Photosynthesis with Polymeric Carbon Nitride: When Meeting Metal Nanoparticles, Single Atoms, and Molecular Complexes.

Artificial photosynthesis for solar water splitting and CO2 reduction to produce hydrogen and hydrocarbon fuels has been considered as one of the most promising ways to solve increasingly serious energy and environmental problems. As a well-documented metal-free semiconductor, polymeric carbon nitride (PCN) has been widely used and intensively investigated for photocatalytic water splitting and CO2 reduction, owing to its physicochemical stability, visible-light response, and facile synthesis. However, PCN as a photocatalyst still suffers from the fast recombination of electron-hole pairs and poor water redox reaction kinetics, greatly restricting its activity for artificial photosynthesis. Among the various modification approaches developed so far, decorating PCN with metals in different existences of nanoparticles, single atoms and molecular complexes, has been evidently very effective to overcome these limitations to improve photocatalytic performances. In this Review article, a systematic introduction to the state-of-the-art metal/PCN photocatalyst systems is given, with metals in versatility of nanoparticles, single atoms, and molecular complexes. Then, the recent processes of the metal/PCN photocatalyst systems in the applications of artificial photosynthesis, e.g., water splitting and CO2 reduction, are reviewed. Finally, the remaining challenges and opportunities for the development of high efficiency metal/PCN photocatalyst systems are presented and prospected.

Genetic characteristics of 19 STRs in Chinese Uzbek ethnic and its phylogenetic relationships with other 24 populations.

Allelic frequencies and genetic polymorphisms of 19 short tandem repeats loci were investigated so as to provide more genetic data for forensic applications in Chinese Uzbek group; besides, we evaluated phylogenetic relationships of Uzbek group with other populations. All loci were observed to conform to Hardy-Weinberg equilibrium after Bonferroni's correction. Two hundred and nine alleles were identified in 212 unrelated healthy Uzbek individuals and their allelic frequencies ranged from 0.0024 to 0.5259. The cumulative discrimination power and cumulative probability of exclusion were 0.999999999999999999999996501 and 0.999999998759, respectively. The results of population differentiation comparison, principal component analysis, and phylogenetic tree revealed that Uzbek group had close relationships with Uyghur and Kazakh groups.

Design, synthesis and tumor cell growth inhibitory activity of 3-nitro-2H-cheromene derivatives as histone deacetylaes inhibitors.

As a continuous research for the discovery of coumarin-based targeted anticancer agents, we designed and synthesized a series of novel histone deacetylases (HDAC) inhibitors using the 8-ethoxy-3-nitro-2H-chromene as the surface binding or cap group, linear dicarboxylic acid or ω-amino acid moiety with different length as the linking motif, ortho-aminoanilides, amides or α-aminoamides as the zinc binding group and the internal cavity motifs. Most of these 3-nitro-2H-chromene derivatives exhibited good growth inhibitory activity against K562, A549, MCF-7, PC3 and Hela cells and were more potent than the reference drug SAHA and MS-275. At the concentration of 10µM, the ortho-aminoanilide series and the d-Phe derived α-aminoamide derivatives 16a and 16b displayed more potent activity toward HADC1 over HADC2, and only moderate to weak activity over HADC6. In contrast, the amide ZBG analogues, 12a and 12b, 14 and 15, were only moderate HDAC6 inhibitors, but more selective over HDAC1 and HDAC2. The ortho-aminoanilides 9b, 9c, 10b, 10c, 11b, and the α-aminoamides 16a and 16b were potent HADC1 inhibitors with the IC50 values in the nanomolar ranges. The ortho-aminoanilides 10b and10c with a phenyl internal cavity motif were more potent than MS-275 as HADC1 inhibitors and more selective over HADC2.

Self-management behaviours in adults with non-alcoholic fatty liver disease: a cross-sectional survey from China.

OBJECTIVES: The prevalence of non-alcoholic fatty liver disease (NAFLD) in China has significantly increased due to changing lifestyles and rising obesity rates. Effective self-management behaviours are crucial for reversing NAFLD. This study aimed to assess the current self-management status and the influencing factors among the Chinese NAFLD population. DESIGN: A cross-sectional study. SETTING: This was a study conducted between 30 May 2022 and 30 May 2023 at a tertiary care hospital. PARTICIPANTS: A total of 380 patients diagnosed with NAFLD were included in this study. NAFLD patients included in this study were diagnosed by FibroScan and had a controlled attenuation parameter ≥248 dB/m. PRIMARY OUTCOMES AND MEASURES: The primary outcomes were self-management, demographic characteristics and clinical features of patients with NAFLD. Self-management-related domains were assessed using the self-management questionnaire of NAFLD. RESULTS: The study included 380 patients with an average age of 42.79±13.77 years, with 62.89% being male. The mean score on the self-management scale was 80.92±18.31, indicating a low level of self-management behaviours. Among the five dimensions of the self-management scale, lifestyle management received the highest score (10.68±2.53), while disease knowledge management received the lowest score (9.29±2.51). Furthermore, gender (ß=0.118, p=0.009), education level (ß=0.118, p=0.010), body mass index (BMI) (ß=-0.141, p=0.002) and sleep quality (ß=0.387, p<0.001) were found to influence the self-management behaviours of patients to some extent. CONCLUSIONS: This cross-sectional survey in China revealed impaired self-management behaviours among adults with NAFLD. The study identified significant associations between self-management behaviours and gender, education level, BMI and sleep quality. Healthcare providers should focus on optimising the care of NAFLD patients to enhance their self-management behaviours.

Preparation of S14161 and its analogues and the discovery of 6-bromo-8-ethoxy-3-nitro-2H-chromene as a more potent antitumor agent in vitro.

The small chemical compound 8-ethoxy-2-(4-fluorophenyl)-3-nitro-2H-chromene (S14161) was recently identified as an inhibitor of the phosphoinositide 3-kinase (PI3K). In the present study, we designed a novel synthesis of S14161 and prepared a series of its analogues via the oxa-Michael-Henry reaction in the presence of catalytic amounts of l-proline and triethylamine. Further structural simplification led to the identification of 6-bromo-8-ethoxy-3-nitro-2H-chromene (BENC-511) that exhibited potent antiproliferative activities against a panel of 12 tumor cell lines. Compared with S14161, BENC-511 was more potent in blocking the AKT phosphorylation and inducing cancer cell apoptosis. BENC-511 also displayed more potent effects on human umbilical vein epithelial cells (HUVEC) migration, suggesting its anti-angiogenesis activity.

Digital Therapeutics: Emerging New Therapy for Nonalcoholic Fatty Liver Disease.

The increased prevalence of nonalcoholic fatty liver disease (NAFLD) worldwide is particularly worrisome, as no medication has been approved to treat the disease. Lifestyle modifications aimed at promoting weight loss and weight maintenance remain the current first-line treatment for NAFLD. However, due to the lack of standard and scientific guidance and out-of-hospital supervision, long-term outcomes of lifestyle interventions for patients with NAFLD are often unsatisfactory. In addition, the COVID-19 pandemic aggravated this dilemma. At the same time, digital therapeutics (DTx) are expected to be a new method for the convenient management and treatment of patients with NAFLD and are attracting a great deal of attention. DTx, which provide evidence-based medicine through software programs for remote intervention in preventing, treating, or managing diseases, overcome the drawbacks of traditional treatment. The efficacy of the approach has already been demonstrated for some chronic diseases, but DTx have not been fully developed for NAFLD. This study reviews the concepts, clinical value, and practical applications related to DTx, with an emphasis on recommendations based on unmet needs for NAFLD. A better understanding of the current state will help clinicians and researchers develop high-quality, standardized, and efficient DTx products, with the aim of optimizing the prognosis of patients with NAFLD.
