Résumé
Background/Aims@#Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. @*Methods@#A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. @*Results@#Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. @*Conclusions@#In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Post-stroke cognitive impairment(PSCI),refers to a range of clinical syndromes of cognitive impairment caused by stroke.Although its specific pathogenesis is still unclear,many studies have confirmed that endoplasmic reticulum-mitochondria interaction has become a key hub for intracellular signal transduction and substance metabolism,and its regulation of various biological processes,such as Ca2+ balance,lipid metabolism,mitochondrial dynamics,autophagy,and neuroinflammation,is closely related to the development of PSCI.There-fore,in this paper,we will review the various functions of endoplasmic reticulum-mitochondrial interactions and explore their specific roles in PSCI,in order to discover new therapeutic targets and provide new theoretical basis and references for the development of PSCI-targeted drugs in the future.
Résumé
Gastric cancer （GC） is one of the most common cancers in the world， with hidden symptoms， complex pathogenesis， high morbidity， high mortality， and poor prognosis. As one of the classical apoptosis pathways， mitochondrial apoptosis has been widely described in the apoptosis escape by GC cells. Mitochondrial apoptosis can regulate the proliferation， invasion， and metastasis of GC cells via oxidative stress， cell cycle， mitochondrial membrane potential， mitochondrial translocation and other mechanisms， and it is one of the potential targets of traditional Chinese medicine （TCM） intervention to restore the mitochondrial function in GC. The theory of spleen-mitochondria in correlation explains that spleen deficiency and cancer toxin are the root causes of mitochondrial apoptosis. Accordingly， the TCM treatment should follow the basic principle of invigorating spleen to restore healthy Qi and removing cancer toxin to eliminate the root cause. Mitochondrial apoptosis can be promoted by inhibiting oxidative stress， promoting cell cycle arrest， and reducing mitochondrial membrane potential. This therapy can improve the energy metabolism， restore the mitochondrial structure and function， and prevent the occurrence and development of GC， with mild side effects and low drug resistance. However， the mechanism of mitochondrial apoptosis in GC and the target of TCM intervention in GC have not been systematically reviewed. Therefore， this paper systematically summarized the effects of mitochondrial apoptosis on the occurrence and development of GC and the role of TCM in the treatment of GC by intervening in mitochondrial apoptosis， aiming to provide a theoretical reference for the treatment and further research of GC.
Résumé
Approximately 50% of patients with non-small-cell lung cancer (NSCLC) are diagnosed at advanced stages and face a challenging prognosis despite the integration of targeted therapies, immunotherapy, and systemic chemotherapy into current standard care. A key factor in this context is trophoblast cell-surface antigen 2 (TROP2), which is widely expressed in NSCLC and strongly associated with poor patient outcomes. This article examines the latest developments in the application of datopotamab deruxtecan (Dato-DXd, DS-1062), a novel antibody-drug conjugate targeting TROP2, in the treatment of NSCLC. It provides a detailed assessment of Dato-DXd’s technical design, evaluates its efficacy by using recent clinical trial data, and discusses its safety profile.
Résumé
BACKGROUND:The application of orthodontic force triggers autophagy in the periodontal tissue via diverse signaling pathways,augmenting or attenuating the activity of relevant cell types such as periodontal ligament cells,osteocytes,osteoclasts,and osteoblasts,thus facilitating the process of periodontal remodeling. OBJECTIVE:To review the research progress in orthodontic force mediated autophagy in periodontal tissue and its impact on orthodontic tooth movement. METHODS:The PubMed,Web of Science,China Biology Medicine disc and CNKI were searched for literature published from 2010 to 2023 to summarize the progress in orthodontics-related autophagy.And 76 papers were finally included in the analysis and discussion. RESULTS AND CONCLUSION:Orthodontic force can trigger a series of biochemical signal changes through periodontal mechanical receptors and aseptic inflammation they cause,leading to autophagy in periodontal tissue.Subsequently,autophagy generates corresponding feedback through cascaded amplified signaling pathways such as Phosphoinositide 3-kinase/protein kinase B,Hippo,and mitogen-activated protein kinase pathways,promoting periodontal tissue remodeling and ultimately achieving tooth movement and stability.Orthodontic force-induced autophagy can differentially regulate bone resorption on the tooth pressure side and bone formation on the tension side.Related targets have good prospects in the clinical application of orthodontic treatment.Orthodontics and autophagy have complex mechanisms.However,existing research has only focused on exploring the role of autophagy in orthodontic tooth movement.Further exploration is needed to investigate the mutual regulatory effects between autophagy and orthodontic tooth movement,as well as the interactions between upstream mechanical receptors and signaling pathways involved in related pathways.

Objective To explore the relationship between different smoking status and hypothyroidism in six iodine-suitable areas of China. Methods A total of 8187 residents were investigated by cluster sampling in six cities, and 7448 residents were included in the survey. The height, weight, waist circumference, and blood pressure were measured by filling out epidemiological questionnaire. Blood samples were collected to detect thyroid stimulating hormone ( TSH) , thyroid peroxidase antibody ( TPOAb) , and thyroglobulin antibody ( TgAb) . Results The mean TSH, TPOAb, and TgAb positive rates in passive smoking and active smoking groups were all lower than those in non-smoking group ( all P<0.01) . In the active smoking group, the TSH value decreased by 0.023 units for every unit increase in smoking index. The positive rates of TgAb and TPOAb in both passive smoking and active smoking groups were lower than those in non-smoking group (all P<0.01). Active and passive smoking reduced the prevalence of hypothyroidism (both P<0.01). Among women, the risks of clinical hypothyroidism and subclinical hypothyroidism were reduced in both active and passive smoking groups. Besides, the risk of subclinical hypothyroidism decreased significantly when the smoking index was more than 70. In male population, the risk of subclinical hypothyroidism in active and passive smoking group decreased. Besides, the risk of clinical hypothyroidism and subclinical hypothyroidism decreased significantly when the smoking index was more than 70. Conclusion Smoking in iodine-suitable areas may reduce TSH level and the positive rates of TPOAb and TgAb.
Résumé
Retinal vein occlusion (RVO) is a vascular disease characterized by intraretinal hemorrhage,edema and hard exudation,which is caused by increased retinal vein pressure.OCT angiography (OCTA) has been widely used in the diagnosis of retinal vascular diseases including RVO by virtue of non-invasive,high resolution and stratified display of superficial,deep retinal vessels and quantification of retinal vessel density and non-perfusion area size.OCTA can provide information of retinal microvascular structure and blood perfusion under the condition of disease,it also can be used to evaluate the effect of treatment and changes of retinal circulation during the course of disease follow-up.Although OCTA cannot replace fundus angiography completely,it has brought us more information about the pathogenesis,disease progression and prognostic factors of RVO.It is believed that with the progress of technology,OCTA will bring us a new chapter in the study of retinal vascular diseases including RVO.
Résumé
Sonic Hedgehog (SHH) signaling pathway participates in the regulation of various organs and growth of tissue cells, maintains normal function and structure in the development of embryogenesis, however, SHH signaling pathway is in a state of inhibition. Meanwhile, the abnormal regulation of SHH signaling pathway plays an important role in the occurrence, development and drug resistance of leukemia. The mechanism of SHH signaling pathway in leukemia is similar to the solid tumor. With the further understanding of SHH signaling pathway, there are many antitumor drugs targeting SHH signaling pathway. The targeting inhibitors targeted SHH signaling pathway will become a new method for the treatment of leukemia. This paper reviews the application of the inhibitors targeting SHH signaling pathway in leukemia.
