ObjectiveTo observe the effects of Danggui Shaoyaosan on macrophage polarization and renal inflammation in db/db mice with diabetic kidney disease (DKD), and to explore its renal protective effects and underlying mechanisms. MethodsEight db/m mice were assigned to the normal group, and forty db/db mice were randomly divided into a model group, low-, medium-, and high-dose Danggui Shaoyaosan groups (8.39, 16.77, 33.54 g·kg-1), and an irbesartan group (0.025 g·kg-1). All mice were administered treatment by gavage for 12 consecutive weeks. General conditions of the mice were observed during the intervention. At the end of the 12-week intervention, 24-h urine samples were collected using metabolic cages, after which the mice were anesthetized for sample collection. Blood was collected by enucleation and centrifuged to obtain serum for the determination of glycated serum protein (GSP), serum creatinine (SCr), blood urea nitrogen (BUN), total cholesterol (TC), and triglycerides (TG). The urinary albumin-to-creatinine ratio (UACR) was measured. Renal pathological changes were observed using hematoxylin-eosin (HE) staining, periodic acid-Schiff (PAS) staining, and Masson staining. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and monocyte chemoattractant protein-1 (MCP-1) levels. Immunofluorescence (IF) was performed to detect F4/80 expression in renal tissue, and immunohistochemistry (IHC) was used to assess CD206 expression. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to measure the mRNA expression of TNF-α, IL-10, inducible nitric oxide synthase (iNOS), and arginase-1 (Arg-1). Western blot analysis was used to detect the protein expression of iNOS, Arg-1, CD86, and CD206 in renal tissue. ResultsCompared with the normal group, the model group showed increased levels of GSP, UACR, SCr, BUN, TC, and TG, elevated levels of the inflammatory factor TNF-α and the chemokine MCP-1, and decreased IL-10 levels (P<0.01). Pathological examination revealed glomerular hypertrophy, mesangial cell proliferation with marked mesangial expansion, inflammatory cell infiltration, vacuolar degeneration of renal tubular epithelial cells, prominent glycogen deposition, and increased collagen fiber deposition. In addition, relative F4/80 fluorescence intensity was enhanced, CD206 expression in the glomeruli and renal interstitium was reduced, and TNF-α and iNOS mRNA expression was increased. IL-10 and Arg-1 mRNA expression was decreased, iNOS and CD86 protein expression was increased, and Arg-1 and CD206 protein expression was decreased (P<0.05, P<0.01). Compared with the model group, the Danggui Shaoyaosan groups and the irbesartan group showed decreased levels of GSP, UACR, SCr, BUN, TC, and TG, reduced serum TNF-α and MCP-1 levels, and increased IL-10 levels. Renal pathological damage was improved to varying degrees. Relative F4/80 fluorescence intensity was reduced, CD206 expression in the glomeruli and renal interstitium was increased, and TNF-α and iNOS mRNA expression was decreased. IL-10 and Arg-1 mRNA expression was increased, iNOS and CD86 protein expression was reduced, and Arg-1 and CD206 protein expression was increased (P<0.05, P<0.01). ConclusionDanggui Shaoyaosan can improve renal function and alleviate renal pathological damage in db/db mice. Its mechanism may be related to inhibiting M1 pro-inflammatory macrophage polarization, promoting M2 anti-inflammatory macrophage polarization, reducing inflammatory responses, delaying the progression of renal fibrosis, improving renal pathological injury, and thereby exerting renal protective effects.

With the rapid rise of large language models(LLM),the natural language generation capabilities of deep learning have demonstrated significant value in the medical field.However,the"closed nature"of model parameters makes them prone to generating"hallucinations",making it difficult to provide accurate answers to the latest knowledge,and the reasoning process lacks transparency and traceability.Retrieval-augmented generation(RAG)technology addresses these issues by actively connecting external information sources such as document databases and knowledge graphs during the generation process.This significantly reduces the dependence of LLM on outdated training data and introduces verifiable evidence and real-time knowledge updates into their responses.In the medical field,RAG technology effectively addresses the high-accuracy and traceability requirements of literature retrieval and clinical decision support.It is widely applied in areas such as drug discovery,pharmacovigilance,and the diagnosis and treatment of rare diseases.By integrating emerging technologies such as reinforcement learning,multimodal processing,and compliant privacy protection,RAG technology is evolving towards a more open and highly customizable direction,providing innovative intelligent solutions for medical information retrieval and decision-making support.

Shengjiangsan is a classic formula for treating warm diseases with wide clinical application and accurate efficacy. There are different opinions on the origin of this formula and lacks key information research on this formula. Therefore, in this study, we conducted systematic research into the historic origin, composition, and other key information of this Shengjiangsan. Results showed that Shengjiangsan has different versions, with "Neixian Fufang", "Jiawei Jianghuangwan", "Peizhensan", and "Taijiwan" being the same formula with different names. Shengjiangsan was first recorded as "Neixian Fufang" in Wanbing Huichun written by GONG Tingxian from the Ming dynasty, inherited and developed by YANG Lishan from Qing dynasty, and has been passed down to modern times. Pills and powder are two main forms of Shengjiangsan, and powder has become more popular nowadays. According to the measurement system of Ming and Qing dynasties, the recommended dosage and usage of Shengjiangsan are as follows. For the pill version of Shengjiangsan, Bombyx Batryticatus of 74.6 g, Curcumae Longae Rhizoma of 9.325 g, Cicadae Periostracum of 9.325 g, and Rhei Radix et Rhizoma of 149.2 g were processed into pills for preparation. Single dosage is Bombyx Batryticatus of 1.15 g, Curcumae Longae Rhizoma of 0.14 g, Cicadae Periostracum of 0.14 g, and Rhei Radix et Rhizoma of 2.3 g, with halved dosage applied for children. For the powder version of Shengjiangsan, the dosage varied in accordance with the severity of the disease. Bombyx Batryticatus of 1.84 g, Curcumae Longae Rhizoma of 0.28 g, Cicadae Periostracum of 0.92 g, and Rhei Radix et Rhizoma of 3.68 g were processed into powder for patients with mild symptoms. Bombyx Batryticatus of 2.48 g, Curcumae Longae Rhizoma of 0.37 g, Cicadae Periostracum of 1.23 g, and Rhei Radix et Rhizoma of 4.91 g were processed into powder for patients with severe symptoms. Bombyx Batryticatus of 3.68 g, Curcumae Longae Rhizoma of 1.84 g, Cicadae Periostracum of 0.55 g, and Rhei Radix et Rhizoma of 7.36 g were processed into powder for patients with critical conditions. In this formula, four herbs were ground to fine powder. For patients with mild symptoms, the whole formula was divided into four dosages, and each dosage weighed 6.71 g. The 200 mL yellow rice wine and 18.65 g honey were added, and the solution was stirred and taken cold till full recovery. For patients with severe symptoms, the whole formula was divided into three dosages, and each weighed 8.95 g. 300 mL yellow rice wine and 27.98 g honey were added, and the solution was stirred and taken cold. For patients with critical conditions, the whole formula was divided into two dosages, and each weighed 13.43 g. 400 mL yellow rice wine and 37.3 g honey were added, and the solution was stirred and taken cold. Shengjiangsan has the effect of ascending lucidity and descending turbidity, dissipating wind, and clearing heat. It is specialized in treating severe heat in exterior, interior, and triple energizers in warm diseases and has a wide modern clinical application. In this study, the historic evolution and key information of Shengjiangsan were reviewed and analyzed, and the key information table of Shengjiangsan was attached, serving as a reference for scholars' research and a theoretical basis for its market transformation.
