Objective: To explore the associations between caregivers nutrition literacy and pediatric nonalcoholic fatty liver disease (NAFLD), so as to provide scientific evidence for the key contents of family intervention measures. Methods: In September 2022, a study involving 1 609 thirdgrade students and their caregivers from six schools in Yinzhou, Haishu, and Zhenhai Districts of Ningbo City, Zhejiang Province, was conducted. Venous blood samples were collected to measure lipid profiles and investigate the prevalence of nonalcoholic fatty liver disease (NAFLD) among the children. Family Food Environment Questionnaire was used to assess the nutrition literacy levels of the caregivers. Generalized linear regression analysis was employed to explore the correlation between caregivers nutrition literacy levels and the prevalence of NAFLD in children. Results: Among the surveyed students, 191 were in the NAFLD group, whereas 1 418 were in the nonNAFLD group. The median nutrition literacy score of caregivers in the NAFLD group and nonNAFLD group all were 11.00 (9.00,12.00), which was not significantly different (Z=-0.40, P=0.71). The generalized linear regression results revealed that the level of nutrition literacy of caregivers had no significant effect on childrens Triglyceride-glucose (TyG) index and Triglyceride-glucose-Waisttoheight ratio (TyG-WHtR) [β(95%CI) were 0.001(-0.005-0.006) and 0.000(-0.014-0.014), P>0.05]. Conclusions The nutrition literacy level of caregivers has no significant correlation with the direct incidence of NAFLD in children. As for family intervention measures, it is necessary not only to improve the nutrition literacy level of caregivers but also to effectively apply nutritional knowledge in practice to optimize health management.

Objective: To evaluates the association between maternal overweight/obesity during pregnancy and offspring risk of metabolic dysfunction associated steatotic liver disease (MASLD), providing theoretical evidence for early life MASLD prevention. Methods: An online search was conducted across ten databases (CNKI, Wanfang, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, PQDT Global, ScienceDirect) for research literature on the association between maternal overweight/obesity during pregnancy and the development of MASLD in offspring, with the search period spanning from January 2014 to December 2024. Two researchers independently screened literature, extracted data, and assessed study quality. Statistical analysis was performed using R 4.3.3. Results: Ten studies involving 10 229 participants were included, comprising 4 cohort studies and 6 case control studies. Cohort studies showed that maternal overweight and obesity significantly increased offspring MASLD risk ( RR=1.59, 95%CI=1.06-2.39, P <0.05), with moderate heterogeneity ( I 2=56.9%, P =0.07). Case control studies indicated a positive association between maternal overweight/obesity during pregnancy and offspring risk of MASLD( OR=2.00, 95%CI=1.68-2.39, P < 0.05), with low heterogeneity ( I 2=48.8%, P =0.08). Conclusions Maternal overweight/obesity during pregnancy positively correlates with offspring MASLD risk. Gestational weight management may reduce the risk.

Thymocyte selection-associated high mobility group box (TOX), a member of the high mobility group protein super-family, plays an important role in T cell development, functional maintenance, and exhaustion. It has been recently found that TOX exerts critical immunoregulatory functions during pathogen infections, and TOX expression is strongly associated with the intensity and tolerance of host immune responses. This review systematically summarizes the structural and functional features of TOX and focuses on its expression dynamics, mechanisms of action, and immunomodulatory effects during viral, bacterial, and parasitic infections, which provides a theoretical support to better understanding of the role of TOX in infectious diseases and provides new insights into development of potential immunotherapeutic strategies targeting TOX.

Repetitive transcranial magnetic stimulation (rTMS) is a rapid and effective therapy for major depressive disorder; however, there is significant variability in therapeutic outcomes both within and across individuals, with approximately 50% of patients showing no response to rTMS treatment. Many studies have personalized the stimulation parameters of rTMS (e.g., location and intensity of stimulation) according to the anatomical and functional structure of the brain. In addition to these parameters, the internal states of the individual, such as circadian rhythm, behavior/cognition, neural oscillation, and neuroplasticity, also contribute to the variation in rTMS effects. In this review, we summarize the current literature on the interaction between rTMS and internal states. We propose two possible methods, multimodal treatment, and adaptive closed-loop treatment, to integrate patients' internal states to achieve better rTMS treatment for depression.

Objective·To investigate the evolution of sarcoma antigen 1(SAGE1),a member of the cancer-testis antigen(CTA)family,in three representative primate species—Macaca mulatta(Rhesus),Callithrix jacchus(Marmoset),and Microcebus murinus(Mouse Lemur),as well as the conservation of its interaction with INTS3,a subunit of the integrator complex.Methods·The interaction between INTS3 and SAGE1 in these primates and the interaction between INTS3 and human SAGE1 mutants were first validated in HEK293T cells by using co-immunoprecipitation(Co-IP).Truncated proteins were then tagged with His-SUMO and GST,respectively,and expressed in Escherichia coli,followed by a series of purification steps to obtain the target proteins.Surface plasmon resonance(SPR)was used to measure the binding affinity of the target proteins,and size exclusion chromatography with multi-angle light scattering(SEC-MALS)was used to determine the stoichiometry of the complex.Additionally,molecular docking was employed to predict the binding model of the truncated SAGE1 and INTS3.Mutations were performed on human SAGE1 key interface residues to analyze their binding to INTS3 by Co-IP.Results·The interaction between the full-length human-derived INTS3 and the full-length SAGE1 from the three primate species was confirmed by Co-IP.Truncated proteins were purified through multiple steps of tandom chromatography.The dissociation constants of the three pairs of truncated INTS3-SAGE1 were measured via SPR,and the SEC-MALS results demonstrated that the binding ratio of INTS3-SAGE1 was 2∶1.Furthermore,molecular docking predicted a structural model of the truncated INTS3-SAGE1 complex and the binding interface was extensively constituted with hydrophobic contacts assisted by some hydrophilic interactions.The interaction between the mutant SAGE1 and INTS3 full-length protein was significantly weakened.Conclusion·There is a conserved interaction between INTS3 and SAGE1 across Rhesus,Marmoset,and Mouse lemur.

Objective To observe the value of multi-slice spiral CT(MSCT)post-processing technologies for diagnosing otosclerosis.Methods Clinical data and original axial plain MSCT of 47 patients with otosclerosis(92 ears)and 65 patients with non-otosclerosis hearing impairment(79 ears)were retrospectively enrolled.MSCT post-processing images,including multi-planar reformation(MPR)of stapes and cochleas and curved planar reformation(CPR)of ossicular chains were obtained.The diagnostic value of original MSCT images alone and raw data of MSCT combing with post-processing images for diagnosing otosclerosis were compared.Results Otosclerosis was correctly diagnosed in 66 ears according to original MSCT images alone,but in 89 ears combined with MSCT post-processing images.The sensitivity of original MSCT images alone and combined with MSCT post-processing images was 71.74％and 96.74％,respectively,and the diagnostic accuracy was 81.29％and 96.49％,respectively,those of the latter were both higher than of the former(both P＜0.05),which had specificities being not significantly different(92.41％vs.96.20％,P＞0.05).Conclusion Combining with post-processing technologies could increase the sensitivity and accuracy of MSCT for diagnosing otosclerosis.

Osteoarthritis （OA） is characterized by articular cartilage degeneration， synovial hyperplasia， hyperosteogeny， and narrowing of joint space， which can be caused by trauma， inflammation， and other factors. With the increasing global population aging， the incidence of OA is rising year by year， making it a major public health problem that urgently needs to be addressed. Exploring effective treatment schemes is particularly important. The pathogenesis of OA is complex， including oxidative stress， autophagy， and apoptosis. Recent studies have found that ferroptosis， a new type of cell death， is also an important pathogenic factor in OA， characterized by a series of complex changes such as iron ion accumulation， glutathione （GSH） depletion， and mitochondrial dysfunction. Research shows that inhibiting ferroptosis in chondrocytes can promote chondrocyte proliferation， delay extracellular matrix （ECM） degradation， and reduce synovial hyperplasia and inflammation. Targeting ferroptosis is a new direction in the treatment of OA. OA treatment includes intra-articular injections of steroids or hyaluronic acid and artificial joint replacement， but there are limitations. Traditional Chinese medicine （TCM） has been widely used in the treatment of various diseases because of its low cost， low drug resistance， and few side effects. Cell and animal experiments have further confirmed that TCM can intervene in the treatment of OA with ferroptosis from multiple targets， multiple levels， and aspects， but the mechanism of its treatment of OA based on ferroptosis has not been clarified. This paper discussed iron metabolism， lipid peroxidation， cysteine/glutamate transporter system Xc^- （system Xc^-）/GSH/glutathione peroxidase 4 （GPX4） pathway， nicotinamide adenine dinucleotide phosphate（NADPH）/ferroptosis suppressor protein 1 （FSP1）/coenzyme Q₁₀ （CoQ₁₀） pathway， tumor protein p53 in OA， and related molecular targets of Chinese medicine monomers and compounds on ferroptosis inhibition. Their potential therapeutic mechanisms were further analyzed to provide theoretical guidance for the treatment of OA by TCM and useful reference for the research and development of related drugs.
