ObjectiveTo investigate the protective effect and mechanism of Wendan Ningxin granules (WNG) on susceptibility to atrial fibrillation (AF) in mice with inflammatory injury. Methods100 C57BL/6 mice were divided into a blank control group, a model group, a low-dose WNG group (2.34 g·kg-1·d-1), a high-dose WNG group (4.68 g·kg-1·d-1), and an amiodarone positive control group (0.091 g·kg-1·d-1), with 20 mice in each group. Except for the blank control group, mice in other groups received intraperitoneal injections of lipopolysaccharide (LPS) to establish an inflammatory injury model. Treatment groups received continuous intragastric administration of their respective interventions for four weeks. During the fourth week, the treatment groups received LPS injections concurrently with their treatments. The blank control and model groups received distilled water (10 mL·kg-1·d-1) by gavage, with a gavage volume of 10 mL·kg-1 for all groups, once daily. Hematoxylin-eosin (HE) staining and Sirius red staining were used to observe atrial tissue morphology and fibrosis degree. Immunohistochemistry was used to assess the expression of α-smooth muscle actin (α-SMA) in mouse atrial tissue. Electrophysiological detection was performed using a multi-channel electrophysiology mapping system to measure AF inducibility, AF duration, and atrial effective refractory period (AERP). High-resolution optical mapping was used to measure action potential duration (APD) dispersion, conduction heterogeneity index, and calcium transient (CaT) dispersion. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression of proteins related to diastolic calcium leakage in mouse atria: Ca2+/calmodulin-dependent protein kinase Ⅱ(CaMKⅡ), ryanodine receptor 2(RyR2), sarco/endoplasmic reticulum Ca²⁺-ATPase (SERCA), and sodium-calcium exchanger (NCX). Western blot analysis was performed to detect the expression of CaMKII, RyR2, SERCA, and NCX proteins in myocardial tissue from each group. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). ResultsPathological staining results showed that compared with the blank control group, the model group exhibited disrupted atrial tissue structure, inflammatory cell infiltration, atrial fibrosis, and diffuse infiltration of numerous brown α-SMA positive cells in the atrial interstitium (P<0.01). AF could be induced by electrical stimulation with a longer duration. AERP was shortened, while APD dispersion, conduction heterogeneity index, and CaT dispersion were increased (P<0.01). The expression of proteins associated with diastolic calcium leakage, including CaMKⅡ, RyR2, and NCX1, showed elevated mRNA and protein levels, whereas SERCA2a mRNA and protein expression decreased (P<0.05). Serum levels of inflammatory factors IL-1β and TNF-α were elevated (P<0.01). Compared with the model group, intervention with WNG alleviated cardiac structural damage, reduced inflammatory cell infiltration, improved atrial fibrosis, and reduced the diffuse infiltration of α-SMA positive cells (P<0.01). AF inducibility and AF duration upon electrical stimulation were significantly reduced (P<0.05), AERP was prolonged (P<0.05), mRNA and protein expression of CaMKⅡ, RyR2, and NCX1-proteins associated with diastolic calcium leakage-were reduced, whilst mRNA and protein expression of SERCA2a increased (P<0.05), and serum levels of IL-1β and TNF-α were decreased (P<0.01). ConclusionBoth low‑ and high‑dose WNG can effectively reduce susceptibility to inflammation-related AF. The mechanism by which WNG reduce AF susceptibility may be related to regulating proteins involved in sarcoplasmic reticulum diastolic calcium leak, thereby improving cardiac electrical remodeling, and alleviating inflammation-induced myocardial fibrosis, thus improving cardiac structural remodeling.

Abstract
The issue of multimorbidity in children and adolescents is becoming increasingly prominent, but there is no consensus on the definition of multimorbidity. As research deepens, issues related to the comparability and standardization of relevant findings are gradually emerging. As a solution, a systematic review of both domestic and international research on multimorbidity is conducted, and a classification system for defining the concept of multimorbidity is proposed, offering more convenient conditions for the advancement of future research and cross study exchange.

ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine (TCM) syndrome elements in different risk populations of heart failure complicated with type 2 diabetes. MethodsClinical data of 675 type 2 diabetes patients were retrospectively collected. Lasso-multivariate Logistic regression was used to construct a clinical prediction nomogram model. Based on this, 441 non-heart failure patients were divided into a low-risk group (325 cases) and a high-risk group (116 cases) according to the median risk score of heart failure complicated with type 2 diabetes. TCM diagnostic information (four diagnostic methods) was collected for both groups, and factor analysis was applied to summarize the distribution of TCM syndrome elements in different risk populations. ResultsLasso-multivariate Logistic regression analysis identified age, disease duration, coronary heart disease, old myocardial infarction, arrhythmia, absolute neutrophil count, activated partial thromboplastin time, and α-hydroxybutyrate dehydrogenase as independent risk factors for heart failure complicated with type 2 diabetes. These were used as final predictive factors to construct the nomogram model. Model validation results showed that the area under the curve (AUC) of the receiver operating characteristic (ROC) curve for the modeling group and validation group were 0.934 and 0.935, respectively. The Hosmer-Lemeshow test (modeling group P = 0.996, validation group P = 0.121) indicated good model discrimination. Decision curve analysis showed that the curves for All and None crossed in the upper right corner, indicating high clinical utility. The low-risk and high-risk groups each obtained 14 common factors. Preliminary analysis revealed that the main disease elements in the low-risk group were qi deficiency (175 cases, 53.85%), dampness (118 cases, 36.31%), and heat (118 cases, 36.31%), with the primary locations in the spleen (125 cases, 38.46%) and lungs (99 cases, 30.46%). In the high-risk group, the main disease elements were yang deficiency (73 cases, 62.93%), blood stasis (68 cases, 58.62%), and heat (49 cases, 42.24%), with the primary locations in the kidney (84 cases, 72.41%) and heart (70 cases, 60.34%). ConclusionThe overall disease characteristics in different risk populations of type 2 diabetes patients with heart failure are a combination of deficiency and excess, with deficiency being predominant. Deficiency and heat are present throughout. The low-risk population mainly shows qi deficiency with dampness and heat, related to the spleen and lungs. The high-risk population shows yang deficiency with blood stasis and heat, related to the kidneys and heart.

Polycystic ovary syndrome (PCOS) is a reproductive endocrine disorder characterized by coexisting reproductive dysfunction and glucolipid metabolic disturbance, affecting 8%-13% of women of reproductive age and 3%-11% of adolescent females. Due to the highly heterogeneous clinical features, symptom-oriented individualized strategies are commonly adopted for the treatment of PCOS. Chronic low-grade inflammation is one of the core mechanisms for the occurrence of PCOS. Macrophages, as foundational cells of innate immunity, play an indispensable role in modulating systemic inflammatory responses. The imbalance of macrophage M1/M2 polarization is involved in chronic low-grade inflammation in PCOS via pathways such as activating pro-inflammatory responses, disrupting ovarian tissue repair, stimulating excessive synthesis of androgens, and promoting the occurrence of insulin resistance. Reshaping the phenotype of macrophages might serve as a potential therapeutic strategy for PCOS. Traditional Chinese medicine (TCM) holds that spleen deficiency and phlegm dampness is a crucial pathogenesis of PCOS. The spleen, being in charge of defensive function, plays a key role in ensuring normal physiological functions such as transportation and defense against external pathogen during the occurrence and development of PCOS. The imbalance of macrophage polarization resembles the transition from spleen being in charge of defensive function to spleen losing its defensive role in TCM. Therefore, this paper, for the first time, explores the deep connection between macrophage polarization and the pathogenesis of chronic low-grade inflammation in PCOS from the TCM theory of spleen being in charge of defensive function, providing theoretical support and new research directions for the treatment and drug research of PCOS.

Objective To explore the effect and mechanism of berberine combined with curcumin on ath-erosclerosis(AS)by mediating M1 macrophages polarization.Methods M1-type macrophages were obtained from mouse mononuclear macrophages(RAW264.7)induced by lipopolysaccharide(LPS,100 ng/mL)and interferon(IFN)-γ(20 ng/mL).A cell model was established.The cells were divided into a control group,model group,berberine group,curcumin group and berberine plus curcumin group.Concentrations of berberine and curcumin were detected by CCK-8 assay.The expression levels of M1-type macrophage markers iNOS,TNF-α,CXCL9 and p-STAT6/STAT6 in macrophage supernatant were detected by ELISA.Levels of iNOS,TNF-α and CXCL9 mRNA were detected by RT-PCR.Levels of iNOS,STAT6 and p-STAT6 proteins in each group were detected by Western blot.After down-regulation of STAT6 level by siRNA technology,expression of p-STAT6 protein was detected by Western blot.Expression levels of iNOS,TNF-α,CXCL9 and p-STAT6 were detected by ELISA.Results In the polarization of M1 macrophages induced by LPS and IFN-γ,berberine(25 μmol/L)and curcumin(20 μmol/L)were the best concentrations as compared with other drug concentration groups,and neither alone nor combined use could significantly inhibit the viability of RAW264.7 cells(P<0.05).As compared with the normal group,iNOS,TNF-α and CXCL9 mRNA and protein levels were increased in the model group,while P-STAT6/STAT6 levels were decreased,with statistical differences(P<0.05).As compared with the model group,iNOS,TNF-α and CXCL9 mRNA and protein levels in the berberine group,curcumin group,and berberine plus curcumin group were decreased,while P-STAT6/STAT6 levels were increased,and the changes were more obvious in berberine plus curcumin group,with statistical difference(P<0.05).After transfection of STAT6 siRNA in M1 macrophages in the berberine plus curcumin group,P-STAT6 levels were down-regulated,while expressions of iNOS,TNF-α and CXCL9 were up-regulated,with statistical differences(P<0.05).Conclusions Both berberine and curcumin can inhibit the activity of M1-type macrophages and reduce inflammatory response.The action of berberine combined with curcumin is more advantageous than that of either drug alone,which may be the main mechanism of action through activation of STAT6.
