Colonic mucosal healing is the ultimate goal of ulcerative colitis (UC) treatment, but it remains difficult to realize. Given the higher incidence of UC in males and the beneficial effect of estrogen on UC, we conducted this study to examine the therapeutic potential of estrogen receptor β (ERβ), the primary ER subtype in colon, on mucosal healing in UC. Our study is the first to report that ERβ activation degree was positively correlated with mucosal healing in patients with UC. Furthermore, ERβ activation enhanced mucosal healing in mice with dextran sulfate sodium-induced and biopsy-induced colonic injuries. Mechanistically, ERβ activation promoted autophagy of colonic epithelial cells by inhibiting branched-chain amino acid transport, leading to focal adhesion kinase (FAK) activation. Activated FAK promoted focal adhesion turnover and colonic epithelial cell migration, ultimately facilitating mucosal healing. ERβ ^-/- colitis mice exhibited impaired mucosal healing compared to wild-type littermates, highlighting the crucial effect of ERβ. Importantly, combination with ERβ-agonist diarylpropionitrile enhanced the amelioration of 5-aminosalicylic acid, a standard UC treatment agent, against mouse colitis. These findings attest to the crucial role of ERβ activation in colonic mucosal healing and may further inform the development of novel strategies for UC treatment.

Although clinical evidence suggests that nonalcoholic fatty liver disease is an established major risk factor for heart failure, it remains unexplored whether sleep disorder-caused hepatic damage contributes to the development of cardiovascular disease (CVD). Here, our findings revealed that sleep fragmentation (SF) displayed notable hepatic detrimental phenotypes, including steatosis and oxidative damage, along with significant abnormalities in cardiac structure and function. All these pathological changes persisted even after sleep recovery for 2 consecutive weeks or more, displaying memory properties. Mechanistically, persistent higher expression of nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) in the liver was the key initiator of SF-accelerated damage phenotypes. SF epigenetically controlled the acetylation of histone H3 lysine 27 (H3K27ac) enrichment at the Nox4 promoter and markedly increased Nox4 expression in liver even after sleep recovery. Moreover, fine coordination of the circadian clock and hepatic damage was strictly controlled by BMAL1-dependent Sirtuin 1 (Sirt1) transcription after circadian misalignment. Accordingly, genetic manipulation of liver-specific Nox4 or Sirt1, along with pharmacological intervention targeting NOX4 (GLX351322) or SIRT1 (Resveratrol), could effectively erase the epigenetic modification of Nox4 by reducing the H3K27ac level and ameliorate the progression of liver pathology, thereby counteracting SF-evoked sustained CVD. Collectively, our findings may pave the way for strategies to mitigate myocardial injury from persistent hepatic detrimental memory in diabetic patients.

A major obstacle in type 2 diabetes mellitus (T2DM) is sleep fragmentation (SF), which negatively affects testicular function. However, the underlying mechanisms remain to be elucidated. In this study, we demonstrate that SF induces testicular damage through a mechanism involving lipid metabolism, specifically mediated by melatonin (MEL) receptor 1a (MT1). T2DM mice with SF intervention displayed several deleterious phenotypes such as apoptosis, deregulated lipid metabolism, and impaired testicular function. Unexpectedly, sleep recovery (SR) for 2 consecutive weeks could not completely abrogate SF's detrimental effects on lipid deposition and testicular function. Interestingly, MEL and MT1 agonist 2-iodomelatonin (2IM) effectively improved lipid homeostasis, highlighting MEL/2IM as a promising therapeutic drug for SF-trigged testicular damage. Mechanistically, MEL and 2IM activated FGFR1 and sequentially restrained the crosstalk and physical interaction between TAB1 and TAK1, which ultimately suppressed the phosphorylation of TAK1 to block lipid deposition and cell apoptosis caused by SF. The ameliorating effect of MEL/2IM was overtly nullified in Fgfr1 knockout (Fgfr1-KO ^+/- ) diabetic mice. Meanwhile, testicular-specific overexpression of Tak1 abolished the protective effect of FGF1^mut on diabetic mouse testis. Our findings offer valuable insights into the molecular mechanisms underlying the testicular pathogenesis associated with SF and propose a novel therapeutic approach for addressing male infertility in T2DM.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

Mesenchymal stem cells are highly regarded for their potential in tissue repair and regenerative medicine due to their multipotency and self-renewal abilities. Recently, mesenchymal stem cells have been redefined as "medical signaling cells," with their primary biological effects mediated through exosome secretion. These exosomes, which contain lipids, proteins, RNA, and metabolites, are crucial in regulating various biological processes and enhancing regenerative therapies. Exosomes replicate the effects of their parent cells while offering benefits such as reduced side effects, low immunogenicity, excellent biocompatibility, and high drug-loading capacity. Dental stem cells, including those from apical papilla, gingiva, dental pulp, and other sources, are key contributors to exosome-mediated regenerative effects, such as tumor cell apoptosis, neuroprotection, angiogenesis, osteogenesis, and immune modulation. Despite their promise, clinical application of exosomes is limited by challenges in isolation techniques. Current methods face issues of complexity, inefficiency, and insufficient purity, hindering detailed analysis. Recent advancements, such as micro-electromechanical systems, alternating current electroosmosis, and serum-free three-dimensional cell cultures, have improved exosome isolation efficacy. This review synthesizes nearly 200 studies on dental stem cell-derived exosomes, highlighting their potential in treating a wide range of conditions, including periodontal diseases, cancer, neurodegenerative disorders, diabetes, and more. Optimized isolation methods offer a path forward for overcoming current limitations and advancing the clinical use of exosome-based therapies.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

BACKGROUND:Copper is an essential trace element and plays a key role in series of physiological activities in the body.Metabolic disturbance of copper is closely associated with multiple diseases.Copper metabolism is mainly involved in the absorption,transport,storage and excretion of copper ions,and all the above processes regulate copper homeostasis in the body.In recent years,many studies have confirmed that copper homeostasis disorder severely affects the metabolic activities of the body and cause diseases in various systems.Besides,the role of copper in oral diseases has been of great interest.OBJECTIVE:To explore the role of copper in occurrence,development,and treatment of oral diseases,and provide a comprehensive overview of research advances in this field.METHODS:The first author searched relevant studies on copper in oral diseases using a computer in PubMed,Web of Science,and CNKI.The key words were"Cu,copper,copper metabolism,oral diseases,oral squamous cell carcinoma,periodontitis,oral submucous fibrosis,oral lichen planus,recurrent oral ulceration,pultitis"in English and Chinese.After screening,78 articles were included for further review and analysis.RESULTS AND CONCLUSION:(1)Patients with oral squamous cell carcinoma have elevated concentrations of copper in serum and saliva,and elevated copper promotes cancer progression through oxidative stress and promoting angiogenesis.Excessive elevation or reduction of copper concentration in tumor cells can inhibit the growth of tumor cells.The combination of copper and anticancer drugs can significantly improve the efficacy of drugs.(2)The concentration of copper in the serum of patients with periodontitis is increased,and excessive copper can aggravate periodontitis through promoting oxidative stress.Combination of copper and drugs can promote periodontal bone regeneration and periodontal tissue healing.(3)The level of copper is positively correlated with degree of oral mucosa fibrosis.Copper that enters the oral mucosa promotes fibrosis of oral mucosa by enhancing activity of lysyloxidase to increase production of collagen.(4)Copper levels are elevated in patients with oral lichen planus,and elevated copper may promote the progression of oral lichen planus by modulating immune cell function.(5)In patients with recurrent oral ulcers,serum copper level is significantly increased,and utilization of copper becomes disordered,which could decrease copper-containing enzyme activity,thus affecting the healing of ulcers.Copper is closely associated with multiple oral diseases and therapies targeting at copper could obviously enhance the therapeutic effect of drugs.But further studies are still needed to uncover its mechanisms to lay foundation for the better treatment of oral diseases.

Objective:To observe the clinical efficacy of snake-like moxibustion combined with aconitum ointment based on routine Western medication in the treatment of ankylosing spondylitis(AS)of cold-dampness blockage pattern,and to evaluate its effects on traditional Chinese medicine(TCM)symptoms,serum Dickkopf-1 protein(DKK-1)level,and disease activity.Methods:A total of 120 AS patients were selected as research subjects and randomly divided into an observation group and a control group according to the random number table method,with 60 cases in each group.The control group was treated with oral sulfasalazine enteric-coated tablets as conventional therapy;the observation group was additionally treated with snake-like moxibustion combined with external application of aconitum ointment based on the intervention in the control group.After 4 weeks of consecutive treatment in both groups,the total effective rate was compared.Changes in TCM symptom scores,spinal pain visual analog scale(VAS)score,overall evaluation VAS score,Bath ankylosing spondylitis disease activity index(BASDAI)score,Bath ankylosing spondylitis functional index(BASFI)score,erythrocyte sedimentation rate(ESR),and serum levels of C-reactive protein(CRP),tumor necrosis factor(TNF)-α,and DKK-1 were observed.Results:The total effective rate in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).After treatment,the scores of TCM symptoms,spinal pain VAS,overall evaluation VAS,BASDAI,and BASFI,as well as ESR,serum levels of CRP,TNF-α,and DKK-1 in both groups were lower than those before treatment,with statistically significant differences within groups(P<0.05);all indicators in the observation group were lower than those in the control group,with statistically significant differences between groups(P<0.05).Conclusion:Based on routine Western medication treatment,the addition of snake-like moxibustion combined with external application of aconitum ointment yields better therapeutic efficacy than Western medication alone in the treatment of AS.It can significantly improve clinical symptoms,control inflammation,and down-regulate the serum DKK-1 level.
