Objective To investigate the mastery of the management knowledge of patients with atrial fibrillation after coronary artery bypass grafting by cardiac surgeons in Beijing tertiary hospitals, and the practice status and obstacles of following the guidelines for postoperative atrial fibrillation. Methods A convenient sampling method was used to select cardiac surgeons from four tertiary hospitals in Beijing, and a self-designed questionnaire on the management of postoperative atrial fibrillation patients was used. Results A total of 227 valid questionnaires were collected. Only 47.9% of doctors and 12.8% of nurses passed in knowledge, and 31.3% of doctors and 28.5% of nurses passed in behavior. Among them, risk factor assessment, preventive medication, stroke and bleeding risk assessment were the weakest. "Lack of departmental requirements" was identified as a common barrier to healthcare workers' adherence to guidelines. Job title and participation in training were common influencing factors that affected the knowledge and behavior of healthcare workers, and knowledge level was an important factor affecting healthcare worker behavior. Conclusion In order to improve the effect of CABG surgery and improve the quality of postoperative patient management, hospitals should further strengthen the knowledge and skills training of medical staff on the management guidelines of postoperative atrial fibrillation with CABG, formulate relevant systems to ensure the clinical implementation of guidelines.

Osteoporosis (OP) is a systemic metabolic disease with a strong correlation with age. The prevalence of osteoporosis is rising annually as a consequence of the growing issue of population ageing. The current treatments for OP have numerous shortcomings. In contrast, traditional Chinese medicine has a long history and a rich species diversity. Furthermore, recent years have seen an increase in the number of studies examining the anti-OP properties of traditional Chinese medicine. This may provide a safe and effective alternative strategy for the treatment of OP. The zebrafish, due to its favourable optical transparency and high homology with human genes, has been extensively employed as an animal research model in the investigation of human skeletal-related disease mechanisms and drug screening. This paper presents a review of anti-osteoporosis studies of traditional Chinese medicine using zebrafish as a model for osteoporosis. It also provides a summary of the experimental evaluation methods involved in such studies, an analysis of the current status of traditional Chinese medicine in the treatment of osteoporosis using zebrafish as a model, and a summary of the mechanism of action and the signalling pathways involved in traditional Chinese medicine in the anti-osteoporosis treatment of zebrafish. The current research status of Chinese medicine in the treatment of OP was analysed, as well as the mechanism of action of Chinese medicine against OP and the signalling pathways involved. Furthermore, the advantages and disadvantages of various zebrafish modelling methods of OP were compared with those of traditional animal models. The objective of this study is to provide a reference for the evaluation method of the zebrafish model in the study of bone-related diseases, as well as for the study of the mechanism of action of traditional Chinese medicine against OP and for the reference of the research and development of new drugs.

ObjectiveTo explore the main mechanism of self-precipitation formed during the decoction of Sinitang(SNT), and to provide a research basis for exploring the differences in the toxic and effective components of this compound. MethodsThe average precipitation yields of SNT, Glycyrrhizae Radix et Rhizoma(GRR)-Aconiti Lateralis Radix Praeparata(ALRP) decoction(GF), ALRP-Zingiberis Rhizoma(ZR) decoction(FJ), GRR-ZR decoction(GJD), ALRP decoction(FZ), ZR decoction(GJ) and GRR decoction(GC) were determined. The four main self-precipitation samples of SNT, GF, FZ and GC were physically characterized by particle size, scanning electron microscopy(SEM), pH, total dissolved solids(TDS), conductivity, and Fourier transform infrared spectroscopy(FT-IR) analysis. The chemical compositions of SNT decoction and its different phases was identified by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) for SNT, SNT self-precipitation and SNT supernatant, and the contents of its main toxic and effective components were determined by high performance liquid chromatography(HPLC). ResultsPrecipitation yield results of the 7 samples of SNT decoction and single decoction showed that SNT had the highest self-precipitation yield. The formation of SNT self-precipitation was mainly related to the reaction between ALRP and GRR components to form complexes, and FT-IR showed that GRR had the greatest influence on the formation of self-precipitation. A total of 110 components were identified in the SNT decoction, including 100 components in the SNT self-precipitation and 106 components in the SNT supernatant. And quantitative results of the main toxic and effective components revealed that the reaction between ALRP and GRR components formed complexes, resulting in the following content hierarchy for free components:SNT decoctionsupernatantself-precipitation, these components included free liquiritin, benzoylmesaconine, benzoylaconitine, benzoylhypacoitine, liquiritigenin, aconitine, hypoaconitine, isoliquiritigenin and ammonium glycyrrhizinate. ConclusionSNT exhibits spontaneous precipitation during compound decoction, with GRR exerting the greatest influence on its formation. This suggests GRR plays a significant role in the detoxification of SNT. The differences in the self-precipitated toxic-effective components of SNT compound decoction primarily manifest as changes in component content, reflecting the characteristics of SNT "deposition in vitro and sustained release in vivo" and the importance of "administered at draught" in the clinical application of SNT.

Tubal ciliary movement is one of the essential transport mechanisms for female fertility, playing a key role in facilitating oocyte pickup and transporting the fertilized ovum. This movement is mediated by multiciliated cells and regulated by specific proteins and hormones that modulate ciliary number, length, polarity, beat frequency, and amplitude to ensure proper function. Genetic mutations, inflammatory stimuli, and hormonal fluctuations can impair ciliary activity or induce ciliary apoptosis, leading to ciliary dysfunction. Disorders of tubal ciliary movement are frequently observed in primary ciliary dyskinesia, pelvic inflammatory disease, polycystic ovary syndrome, and endometriosis, conditions commonly associated with female infertility. These disorders manifest as structural abnormalities of cilia, disrupted polarity, shortened ciliary length, reduced ciliary count, and decreased beat frequency and amplitude. Understanding the role of tubal ciliary movement in female infertility-related diseases, through immunohistochemistry and ultrastructural analysis, helps clarify underlying infertility mechanisms. Identifying abnormal inflammatory factors, hormonal environments, and gene expression, combined with advanced techniques for measuring ciliary protein and beat frequency, may offer novel clinical targets for early prevention and treatment of female infertility.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

The prefrontal cortex (PFC) plays a pivotal role in orchestrating higher-order emotional and cognitive processes, a function that depends on the precise modulation of synaptic activity. Although pharmacological studies have demonstrated that dopamine signaling through dopamine D1 receptor (DRD1) in the PFC is essential for these functions, the cell-type-specific and molecular mechanisms underlying the neuromodulatory effects remain elusive. Using cell-type-specific knockout mice and patch-clamp recordings, we investigated the regulatory role of DRD1 on neurons and astrocytes in synaptic transmission and plasticity. Furthermore, we explored the mechanisms by which DRD1 on astrocytes regulate synaptic transmission and plasticity at the cellular level, as well as emotional and cognitive functions at the behavioral level, through two-photon imaging, microdialysis, high-performance liquid chromatography, transcriptome sequencing, and behavioral testing. We found that conditional knockout of the Drd1 in astrocytes (CKOAST) increased glutamatergic synaptic transmission and long-term potentiation (LTP) in the medial prefrontal cortex (mPFC), whereas Drd1 deletion in pyramidal neurons did not affect synaptic transmission. The elevated level of d-serine in the mPFC of CKOAST mice increased glutamatergic transmission and LTP through NMDA receptors. In addition, CKOAST mice exhibited abnormal emotional and cognitive function. Notably, these behavioral changes in CKOAST mice could be reversed through the administration of d-serine degrease to the mPFC. These results highlight the critical role of the astrocytic DRD1 in modulating mPFC synaptic transmission and plasticity, as well as higher brain functions through d-serine, and may shed light on the treatment of mental disorders.

Myocardial fibrosis (MF) is a common pathological manifestation of various heart diseases. Due to the non-renewable nature of myocardial cells, the occurrence of MF represents irreversible damage to the myocardium. Previous studies have suggested that fibroblast-mediated collagen deposition is the main mechanism of MF. Recent studies have found that there is an immune regulation mechanism in the heart itself, and macrophage activation/polarization plays an important role in MF. With the deepening of traditional Chinese medicine research, scholars have found that traditional Chinese medicine can interfere with MF by regulating the renin-angiotensin-aldosterone system (RAAS) system and the inflammatory process, repairing the extracellular matrix, managing oxidative stress, and maintaining the balance of autophagy. This process is closely related to the activation and M1/M2 polarization of macrophages. Throughout the MF process, macrophage activation is beneficial, but excessive activation will be harmful. In the early stage of MF, appropriate M1 macrophage polarization is conducive to activating immunity and removing harmful substances. In the middle and late stages of MF, appropriate M2 macrophage polarization is conducive to remodeling the damaged myocardium. If macrophage activation is excessive/insufficient, or the balance of M1/M2 macrophage polarization is broken, the effect changes from improvement to destruction. Traditional Chinese medicines that regulate the activation/polarization of macrophages have the effects of replenishing Qi and nourishing Yin, as well as regulating Qi and activating blood, but there are also some heat-clearing, dampness-drying, and detoxification products. Therefore, the occurrence of MF may be caused by Qi and Yin deficiency, damp heat accumulation, and Qi stagnation and blood stasis. By summarizing the biological processes involved in macrophage activation/polarization in MF, this paper expounded on the research progress of traditional Chinese medicine in regulating macrophage activation and M1/M2 polarization from different angles to improve MF, so as to provide a reference for the treatment of MF with traditional Chinese medicine.

Objective To investigate the prevalence and molecular characteristics of Anaplasma infections in sheep and goats in Anhui Province in 2020, so as to provide insights into ovine anaplasmosis prevention and control. Methods A total of 355 fresh blood samples were collected from 7 sheep and goat farms in Linquan County of Fuyang City, Lixin County of Bozhou City, Yu'an District of Lu'an City, Wangjiang County of Anqing City, Nanling County of Wuhu City, and Tianchang City and Fengyang County of Chuzhou City in Anhui Province from June to December 2020. A. bovis and A. phagocytophilum 16S ribosomal RNA (16S rRNA) gene, A. ovis major surface protein 4 (MSP4) gene and A. capra citric acid synthase (gltA) gene were amplified using PCR assay in all blood samples, and the prevalence of A. bovis, A. phagocytophilum, A. ovis and A. capra infections was calculated in sheep and goats. In addition, the positive amplification products were sequenced and subjected to genetic evolutionary analysis. Results The overall prevalence of Anaplasma infections was 17.5% (62/355) in sheep and goats in Anhui Province, and the prevalence of A. bovis, A. phagocytophilum, A. ovis and A. capra infections was 2.8% (10/355), 2.5% (9/355), 2.5% (9/355), and 7.0% (25/355), while the prevalence of A. bovis and A. phagocytophilum, A. phagocytophilum and A. ovis, A. phagocytophilum and A. capra and A. bovis, A. phagocytophilum and A. ovis co-infections was 0.8% (3/355), 1.1% (4/355), 0.3% (1/355) and 0.3% (1/355), respectively. No Anaplasma was detected in the sheep and goat farms in Fengyang County, while at least three Anaplasma species were detected in other sheep and goat farms, with co-infections of multiple Anaplasma species identified. The prevalence of Anaplasma infections was 14.7% (24/163) in goats and 19.8% (38/192) in sheep, and the prevalence of Anaplasma infections was 31.0% (31/100) in goats and sheep under 6 months of age, and 12.2% (31/255) in goats and sheep at ages of 6 months and older, respectively. A. bovis, A. phagocytophilum, A. ovis and A. capra were identified in sheep and goats of different breeds and ages. Conclusions Multiple Anaplasma species infections were commonly prevalent in goats and sheep in Anhui Province in 2020, notably A. phagocytophilum, A. ovis and A. capra, which have zoonotic risks. Improved surveillance and prevention and control of Anaplasma infections are required in sheep and goats in Anhui Province.
