心肌纤维化是心力衰竭等心血管疾病演化过程中的关键性病理改变，该病的进展机制依赖巨噬细胞与成纤维细胞的相互调控。现有现代医学研究证实巨噬细胞可凭借M1、M2表型极化行为介导炎症反应与组织修复过程，成纤维细胞能够分化形成肌成纤维细胞并推动细胞外基质异常沉积，两类细胞可依托TGF-β/Smad、CSF-1/CSF-1R等信号通路构建相互调控的作用网络并介导心肌纤维化恶化。中医痰瘀互结病机理论指出痰浊与瘀血可相互滋生、交织阻滞，是各类慢性迁延性疾病的关键发病基础。本文以中医痰瘀互结理论为研究切入点，剖析该病机理论与巨噬细胞、成纤维细胞交互作用的内在关联，整合现代医学关于两种细胞交互作用的现有研究成果，深入分析细胞互作在心肌纤维化发病过程中的协同机制与病理关联，旨在为心肌纤维化的中西医协同防治提供理论依据，为相关动物实验及临床应用研究筑牢研究基础。

Myocardial fibrosis is a key pathological change in the progression of cardiovascular diseases such as heart failure. The progression mechanism of this disease relies on the reciprocal regulation between macrophages and fibroblasts. Current modern medical research has confirmed that macrophages can mediate inflammatory responses and tissue repair processes through M1 and M2 phenotypic polarization behaviors, and fibroblasts can differentiate into myofibroblasts and promote abnormal extracellular matrix deposition. The two types of cells can construct a reciprocal regulatory network through signaling pathways such as TGF-β/Smad and CSF-1/CSF-1R, thereby mediating the deterioration of myocardial fibrosis. The theory of phlegm and blood stasis intermingling in traditional Chinese medicine suggests that phlegm turbidity and blood stasis can mutually generate and interweave to cause obstruction, serving as a key pathological basis for various chronic and persistent diseases. This article takes the traditional Chinese medicine theory of phlegmblood stasis intermingling as a research entry point, analyzes the intrinsic relationship between this pathological theory and the interaction of macrophages and fibroblasts, integrates existing modern medical research findings on the interaction between the two cell types, and deeply analyzes the synergistic mechanisms and pathological correlations of cellcell interactions in the pathogenesis of myocardial fibrosis. The aim is to provide a theoretical basis for the integrated traditional Chinese and Western medicine prevention and treatment of myocardial fibrosis, and also to lay a solid research foundation for related animal experiments and clinical application studies.

Chronic kidney disease (CKD) is a series of chronic disease groups associated with high morbidity and mortality. Hemodialysis and kidney transplantation are the only choices for end-stage renal disease. According to the literature report, it is shown that small molecule and nucleic acid drugs have great potential in CKD treatments with an unsatisfied therapeutic efficacy because of the lack of specific targeting. Thus, it is necessary to develop a new strategy. Nanocarriers have been widely used in biomedical fields due to their excellent physical and chemical properties. In this review, we have summarized the recent advances in applying functional nanocarriers to deliver the small molecules and nucleic acid drugs in the treatment of CKD.

Objective To observe the expression of tight junction protein in hyperuricemia induced renal damage model in rats and the intervention effect of febuxostat. Methods SD rats were randomly divided into three groups: normal control group, model control group, febuxostat treatment group. Hyperuricemia was induced in rats with oxonic acid per time for three times per day, by gavage and combined with uric acid added in drinking water, while febuxostat were administered by gavage in febuxostat treatment group.The blood of rats were collected to analyse the differences of control, model and treatment group on changes of blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA). Immunohistochemistry was used to assay ZO-1 and occludin protein expression and quantitive real time PCR to detect the expression of ZO-1 and occludin in renal tissue of renal interstitial fibrosis model rats induced by hyperuricemia. Paraffin section of kidney was maked and then performed Masson staining to make sure the model is successful. Results At 6 weeks, the expressions of ZO-1 and occludin in the model group and treatment group were lower than those in the normal group (all P<0.05). The expressions of ZO-1 and occludin in the treatment group were higher than those in the model group (all P<0.05). Compared with the normal group, the RIF index in the model group and treatment group were higher (all P<0.05), and the RIF index in the treatment group was lower than that in the model group and higher than that in the normal group (all P<0.05). Conclusion The downregulated expression of ZO-1 and occludin plays a crucial role during the development of hyperuricemia in renal interstitial fibrosis, and are closely related to UA level and renal function impairment. Febuxostat may improve the expression of tight junction by downregurating UA, reduce renal fuction impairment and play a role in renal protection.
