Based on the data from the 5^th National Physical Fitness Surveillance in China, this study aimed to explore the relationship between abnormal body weight and physical fitness levels in older adults.

“Deficiency cause， cold accumulation， and qi stagnation” originates from Essentials from the Golden Cabinet （《金匮要略》）， which is a guiding principle for the pathogenesis of women's diseases， pioneering the differentiation and treatment of women's diseases based on patterns， and having a profound influence on future generations. Following the classical principles and simplifying the complexities， this paper explored the pathogenesis and mechanism of polycystic ovary syndrome （PCOS） from the perspective of “deficiency cause， cold accumulation， and qi stagnation”， and believed that depletion of essence and blood， long-term accumulation of internal cold， and qi constraint and blood stasis are the causes of PCOS， with depletion of essence and blood， and lack of nourishment of zang-fu （脏腑） organs as the root， and cold pathogen invasion， qi constraint and blood stasis as the branch. The main treatment principle is “treating deficiency with supplementation”， and dispelling pathogen while reinforcing healthy qi， along with “treatment of cold by warming” and “treatment of stagnation by dispersing”. This is of great significance for the treatment of polycystic ovary syndrome. Clinically， these methods can be used flexibly to guide treatment and formula selection for PCOS， with the goal of harmonizing qi and blood and regulating menstruation.

Objective:To explore the effects of type D personality on mild cognitive dysfunction (MCI) in patients with coronary heart disease and the multiple mediating roles of dietary inflammation index (DII) and systemic immune inflammation index (SII) between type D personality and MCI.Methods:A cross-sectional study was used. A total of 321 patients diagnosed with coronary heart disease by coronary angiography in the Second Affiliated Hospital of Harbin Medical University from May 2022 to March 2023 were selected as the study objects by convenient sampling method. General Information Questionnaire, Type-D Personality Scale-14, Montreal Cognitive Assessment, and Semi-Quantitative Food Frequency Questionnaire were employed for data collection. DII and SII were used to evaluate dietary inflammatory potential and systemic inflammatory status, respectively. Structural equation modeling was utilized to analyze the mediating effectsamong type D personality, DII, SII and MCI.Results:A total of 306 valid questionnaires were collected. Among the 306 patients, there were 215 males (70.3%) and 91 females (29.7%), aged 27-70 (59.24 ± 9.16) years old. The structural equation model showed that type D personality could directly influence MCI (effect size = - 1.098, 95% CI - 1.869 - - 0.327), and could also mediate the occurrence of MCI in coronary heart disease patients through the single mediation of DII (effect size = - 0.374, 95% CI - 0.644 - - 0.128) and SII (effect size = - 0.450, 95% CI - 0.806 - - 0.132), as well as the chain mediation of DII and SII (effect size = - 0.146, 95% CI - 0.293 - - 0.027). Conclusions:Type D personality, DII and SII can affect the occurrence of MCI in CHD patients, and DII and SII play multiple mediating roles between type D personality and MCI in patients with coronary heart disease. Clinical and community nurses can improve the unhealthy dietary behavior, reduce the level of inflammation and delay the occurrence and development of MCI by early screening of type D personality in patients with coronary heart disease.

Hemophagocytic syndrome (HPS), which is currently named as hemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory syndrome characterized by persistent fever, hepatosplenomegaly, pancytopenia and hemophagocytosis found in bone marrow, liver, spleen and lymph nodes due to excessive activation of macrophages and cytotoxic T cells. Macrophage activation syndrome (MAS) is a specific form of HLH induced by autoinflammatory/autoimmune disorders which can be life-threatening and requires multiple disciplines. In order to improve clinicians′ understanding of MAS and standardize the clinical diagnosis and treatment practice of MAS, the rheumatology branch of Chinese Rheumatology Association organized domestic experts to formulate the diagnosis and treatment standard, in order to improve the diagnosis and treatment level of MAS and improve the prognosis of patients.

METTL3 and METTL14 are two components that form the core heterodimer of the main RNA m6A methyltransferase complex (MTC) that installs m6A. Surprisingly, depletion of METTL3 or METTL14 displayed distinct effects on stemness maintenance of mouse embryonic stem cell (mESC). While comparable global hypo-methylation in RNA m6A was observed in Mettl3 or Mettl14 knockout mESCs, respectively. Mettl14 knockout led to a globally decreased nascent RNA synthesis, whereas Mettl3 depletion resulted in transcription upregulation, suggesting that METTL14 might possess an m6A-independent role in gene regulation. We found that METTL14 colocalizes with the repressive H3K27me3 modification. Mechanistically, METTL14, but not METTL3, binds H3K27me3 and recruits KDM6B to induce H3K27me3 demethylation independent of METTL3. Depletion of METTL14 thus led to a global increase in H3K27me3 level along with a global gene suppression. The effects of METTL14 on regulation of H3K27me3 is essential for the transition from self-renewal to differentiation of mESCs. This work reveals a regulatory mechanism on heterochromatin by METTL14 in a manner distinct from METTL3 and independently of m6A, and critically impacts transcriptional regulation, stemness maintenance, and differentiation of mESCs.

As a co-stimulatory blocker against CD28 receptor, belatacept has been approved and applied to the treatment of rejection in organ transplantation in Europe and America. Belatacept has been proven to outperform calcineurin inhibitor (CNI) in improving the long-term survival rate of recipients and grafts, and enhancing graft function. Nevertheless, it might cause a high incidence of rejection. To resolve this issue, transplant workers have attempted to optimize belatacept immunosuppressive regimen and achieved good clinical efficacy. Although belatacept has been proven to exert poor effect on memory T cells, it has potential value in exploring new co-stimulatory molecular targets to optimize immunosuppressive regimes due to its specificity for immune cells and mild adverse effects. In this article, the advent of co-stimulatory blocker, clinical efficacy and application of belatacept, and the causes of belatacept-resistant rejection were reviewed.

Objective To explore whether Rho kinase inhibitor protects endotoxemia mice from kidney injury,and to investigate the mechanism underlying this effect. Methods Adult male C57BL/6 mice were randomly divided into three groups (n = 8 for each group): control,lipopolysaccharide (LPS),and LPS+ Y-27632 (Rho kinase inhibitor). For induction of acute kidney injury,mice were administered 30 mg/kg LPS intraperitoneally. Y-27632 (10 mg/kg body weight) was injected intraperitoneally 18 h and 1 h before injection of LPS,and an equal volume of sterile saline was administered at the corresponding time point in each group. The mice were killed 8 h after LPS administration. Blood samples and kidney tissues were taken and preserved for subsequent analysis. Results Pretreatment with Y-27632 significantly attenuated LPS-induced kidney injury;pretreatment with Y-27632 markedly reduced renal expression of inflammatory cytokines (TNF-α and IL-1β) in endotoxemia mouse,and also significantly inhibited LPS-induced caspase-3 expression in the kidney; and Y-27632 pretreatment dramatically reduced TLR4 protein expression and NF-κBp65 phosphorylation in kidney tissues of endotoxemia mouse. Conclusion Rho kinase inhibitor may inhibit TLR4 and NF-κB signaling pathway to reduce the inflammatory response in the kidneys of endotoxemia mice and alleviate acute renal injury induced by LPS.
