ObjectiveThis paper aims to observe the protective effect of Huamoyan granules on knee osteoarthritis (KOA) and explore whether its protective effect is oriented toward an anti-inflammatory direction by regulation of macrophage polarization, which can effectively inhibit the progression of pathological inflammatory response, reduce the release of inflammatory pain mediators, and downregulate the protein expression level of transient receptor potential vanilloid 1 (TRPV1), so as to provide experimental evidence for its clinical application and investigate its action mechanism. MethodsAfter adaptive feeding, Sprague-Dawley (SD) rats were randomly divided into six groups: sham group, model group, celecoxib group, and high, medium, and low-dose synovitis granule groups (9.6, 4.8, 2.4 g·kg-1). The administration dose of celecoxib capsules was 20 mg·kg-1. There were 10 rats in the sham group and 12 rats in the model group and each administration group. A KOA animal model was established by means of intra-articular injection of sodium iodoacetate into the knee joint. From the 10th day of the experiment, each administration group was given intragastric administration at a dose of 10 mL·kg-1 for 4 weeks. General conditions of rats in each group were assessed daily. The pressure pain threshold (PPT) to mechanical stimulation and joint diameter were recorded. X-ray examination was performed on the right knee joints of rats for imaging analysis. Enzyme linked immunosorbent assay (ELISA) was performed to detect the tumor necrosis factor-α (TNF-α), serum interleukin-1β (IL-1β), and other pro-inflammatory cytokines in rat serum samples, as well as the expression levels of neurogenic inflammatory mediators such as nerve growth factor (NGF) and calcitonin gene-related peptide (CGRP). Histopathological changes in the knee joint synovial tissues were examined by hematoxylineosin (HE) staining. Safranin O-fast green staining was performed to observe and evaluate the degree of knee cartilage lesions. Western blot was employed to quantitatively analyze TRPV1, p38 mitogen-activated protein kinase (p38 MAPK), and phosphorylated (p)-p38 MAPK in rat knee synovial tissues. Immunofluorescence (IF) was used to measure and assess M1/M2 macrophage polarization. ResultsCompared with those in the sham group, the circumference and joint diameter of the right knee were markedly enlarged in the model group (P<0.01), while PPTs of rats showed a significant reduction (P<0.01). The contents of IL-1β, TNF-α, CGRP, and NGF in rats' serum were significantly elevated (P<0.01), and the synovial Krenn score was increased (P<0.01). The Mankin score of cartilage tissue was increased (P<0.01), and the protein expressions of TRPV1 and p-p38 MAPK/p38 MAPK were significantly upregulated (P<0.01). The experimental intervention significantly reduced the proportion of pro-inflammatory M1 macrophages in the total macrophage population (P<0.01), and the percentage of M2 macrophages was decreased (P<0.01). The M1/M2 macrophage ratio was significantly elevated (P<0.01). Knee joint diameters of all dose groups of Huamoyan granules and the celecoxib group were reduced (P<0.01) compared with those of the model group, and the PPT recovery speeds in the high and medium-dose groups of Huamoyan granules were more obvious (P<0.05). The contents of IL-1β, CGRP, and NGF in the rats' serum in all administration groups were significantly reduced (P<0.05, P<0.01), and the content of TNF-α in rats' serum was significantly reduced (P<0.01). All dose groups of Huamoyan granules demonstrated significant reductions in both synovial Krenn score (P<0.05, P<0.01) and protein expression of TRPV1 and p-p38 MAPK/p38 MAPK in rats' synovial tissues (P<0.01). The percentage of M1 macrophages in the synovial tissues of the celecoxib group and all dose groups of Huamoyan granules was decreased (P<0.01). The percentage of M2 macrophages was increased (P<0.05), and the M1/M2 ratio was decreased (P<0.01). ConclusionHuamoyan granules can alleviate the inflammatory response of KOA, reduce the release of inflammatory pain mediators, and downregulate TRPV1 protein expression by regulating macrophage polarization. Its mechanism may be related to the TRPV1/p38 MAPK signaling pathway, thereby achieving the effect of improving peripheral pain hypersensitivity in KOA.

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage (Shang Han Lun). This prescription is composed of Bupleuri Radix, Scutellariae Radix, Cinnamomi Ramulus, Zingiberis Rhizoma, Trichosanthis Radix, Ostreae Concha, and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang, warming the spleen, and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis (CC), irritable bowel syndrome, and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain, poor appetite, postprandial fullness, aversion to greasy food, soft stool, and bitter mouth, being a type of biliary dyspepsia. In modern medicine, dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation, promoting the function of gallbladder, resolving stones, alleviating spasms, and relieving the pain for CC, demonstrating definite short-term efficacy but suffering from single effects, high recurrence rate, and poor compliance. Although surgical treatment can cure cholecystitis, it is accompanied by the increased incidence of adverse events such as abdominal pain, diarrhea, and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins, baicalin, cinnamaldehyde, gingerol, Trichosanthis Radix polysaccharide, Ostreae Concha polysaccharide, and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses, improving gallbladder contraction and gastrointestinal motility, regulating the bile acid-intestinal flora axis and the brain-gut axis, and modulating blood lipids through multiple targets. By reviewing the previous literature, this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

OBJECTIVE To investigate a dynamic monitoring of drug consumption (DMDC) model based on the seasonal Mann-Kendall trend test, aiming to provide scientific evidence for the efficient and macroscopic monitoring of drug use. METHODS A monitoring list of key outpatient drugs was established based on the top 20% of drugs ranked by sales volume in the outpatient pharmacy in October 2024. A DMDC model based on the Mann-Kendall trend test was constructed using the monthly usage data of key outpatient drugs from November 2021 to October 2024, aiming to eliminate the impact of seasonal fluctuations and analyze the temporal trends in drug consumption. Taking mucolytic expectorants, triazole derivatives for dermatophytosis, and single-agent hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors as examples, the monitoring effectiveness of the DMDC model was demonstrated, and its performance was compared with that achieved by the traditional sequential growth rate ranking method. RESULTS A total of 215 drug varieties were included in the monitoring list, and DMDC models were successfully established for all of them. Among these, 119 showed a significant increasing trend (P<0.05, S′>0). The model successfully monitored the monthly consumption of mucolytic expectorants, triazole derivatives for dermatophytosis, and single- agent HMG-CoA reductase inhibitors. The precision and recall rates of the DMDC model for identifying abnormal drug use were 60.7% and 85.0%, respectively, both significantly higher than those of the sequential growth rate ranking method (8.3% and 15.0%, respectively) (χ2=20.114, P<0.001; χ2=19.600, P<0.001). CONCLUSIONS DMDC model based on the seasonal Mann-Kendall trend test can effectively identify long-term trends in drug consumption, eliminate seasonal interference, enhance monitoring accuracy and management efficiency, and is suitable for the dynamic monitoring of drug consumption.

As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

Stroke is the leading cause of death and disability among adults in China, and its common complications include digestive system abnormalities, cognitive impairment, depression, stroke-associated pneumonia, and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang (XLCQT) is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically, XLCQT is often used to treat stroke and its complications. However, the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally, since the basic research is weak, the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis, medicinal properties, safety evaluation, and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients, resveratrol, kaempferol, luteolin, chrysoeriol, apigenin, (+)-catechin, and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex, including inflammatory response, brain-gut axis, hypothalamic-pituitary-adrenal (HPA) axis, intestinal flora, neurotrophic factors, autophagy, oxidative stress, and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective: To investigate the identification process of a case with anti-Fy
combined with Rh blood group system antibodies and to review the transfusion strategy and epidemiological characteristics of Duffy blood group system antibodies. Methods: The antibody specificity of a patient diagnosed with liver cirrhosis, who exhibited unexpected antibodies, was determined using the microcolumn gel method, enzyme method, and elution test. A retrospective analysis was performed to assess the incidence and clinical characteristics of antibodies associated with the Duffy blood group system among a cohort of 652 003 patients treated at our hospital from 2014 to 2024. Results: The patient's serum contained anti-Fy
, anti-c, and anti-E antibodies. Through the targeted recruitment of African international students, the patient successfully received four units of Fy
-negative blood that matched the ABO and Rh phenotypes. Between 2014 and 2024, the incidence of Duffy blood group system antibodies was 0.005 7% (37 out of 652 003), with 9 cases (24.3%) combined with Rh antibodies. Conclusion: Patients with anti-Fy
combined with Rh antibodies require Fy
-negative blood with matched Rh phenotypes. Targeted recruitment based on racial antigen differences can effectively resolve rare blood type transfusion challenges.

ObjectiveTo evaluate the therapeutic effect of Huazhuo SanJie Chubi presciption (HSCD) on chronic gouty arthritis (CGA) rats with low-grade inflammation and to explore the underlying mechanism with a focus on macrophage polarization. MethodsThe 41 male 6-week-old SD rats were randomly allocated, using the random number table, to a normal group (n=8) and a model group (n =33). CGA with low-grade inflammation was induced in the model group by daily gavage of potassium oxonate (250 mg·kg-1·d-1) and hypoxanthine (300 mg·kg-1·d-1), combined with intra-articular injection of a monosodium urate (MSU) crystal suspension (50 μL, 25 g·L-¹) into the left ankle twice weekly. After 4 weeks of modeling, 3 rats were randomly selected from each group for model validation. The remaining successfully modeled rats were randomly divided into a model group, an HSCD group (10.35 g·kg-1·d-1, gavage once daily), an M1 polarization agonist group (L-methionine sulfoximine, 300 mg·kg-1, subcutaneous injection every other day), an M1 polarization agonist + HSCD group, an M2 polarization inhibitor group (PD0325901, 10 mg·kg-1·d-1, gavage once daily), and M2 polarization inhibitor + HSCD group. The corresponding drug or drug combination was administered according to group assignment, whereas rats in the normal and model groups received 0.5% carboxymethyl cellulose sodium (CMC-Na) vehicle (10.35 g·kg-1·d-1, gavage once daily). All interventions were continued for four weeks. During the intervention period, except for the normal group, potassium oxonate (250 mg·kg⁻¹) and hypoxanthine (300 mg·kg-1) were co-administered by gavage every other day to maintain the model. At the end of treatment, serum uric acid (SUA), ankle joint diameter and joint swelling index were measured. The levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), chemokine C-C motif ligand 2 (CCL2), S100 calcium-binding protein A8/A9 (S100A8/A9), interleukin-10 (IL-10) and arginase-1 (Arg-1) in serum and joint fluid were determined by enzyme-linked immunosorbent assay (ELISA). High-frequency ultrasound was used to assess MSU deposition in the ankle joint. Hematoxylin-eosin (HE) staining was performed to evaluate synovial histopathological changes. Quantitative Real-time PCR and immunofluorescence were used to detect the mRNA and protein expression of the M1 macrophage polarization markers inducible nitric oxide synthase (iNOS) and the M2 macrophage polarization marker scavenger receptor cysteine-rich type 1 protein M130 (CD163) in synovial tissue. ResultsCompared with the normal group, the model group showed significantly elevated SUA level and joint swelling index, and increased levels of pro-inflammatory cytokines, CCL2, and S100A8/A9 in both serum and joint fluid (P<0.05), accompanied by MSU deposition and synovial inflammation in the ankle joint. The mRNA and protein expression levels of macrophage polarization M1/M2 markers iNOS and CD163 in synovial tissues were also significantly up-regulated (P<0.05). Compared with model group, rats in HSCD group had significantly lower SUA levels, attenuated joint swelling, reduced serum levels of pro-inflammatory cytokines, and decreased levels of CCL2 and S100A8/A9 in both serum and joint fluid, accompanied with alleviated MSU deposition and synovial inflammation (P<0.05). HSCD markedly downregulated the mRNA and protein expression of M1 marker iNOS (P<0.05), whereas it had no significant effect on the expression of M2 marker CD163. Compared with the M1 polarization agonist group, the M1 polarization agonist + HSCD group showed significantly reduced joint swelling, lower serum levels of pro-inflammatory cytokines, and decreased levels of CCL2 and S100A8/A9 in joint fluid (P<0.05). In addition, synovial inflammatory cell infiltration and angiogenesis were attenuated, and iNOS mRNA and protein expression levels were significantly reduced (P<0.05). Compared with the M2 polarization inhibitor group, the M2 polarization inhibitor + HSCD group exhibited reduced joint swelling, decreased levels of CCL2 and S100A8/A9 in joint fluid and ameliorated synovial inflammation (P<0.05), whereas the levels of anti-inflammatory mediators (IL-10, Arg-1) and CD163 mRNA and protein expression were not significantly increased. ConclusionHSCD alleviates low-grade inflammation in CGA rats, at least in part, by inhibiting macrophage polarization toward the M1 phenotype.

ObjectiveThis paper aims to observe the effect of Huazhuo Sanjie Chubi prescription (HSCD) on the gouty bone erosion model rats and investigate its action mechanism. MethodsThirty-six two-month-old male SD rats were randomly divided into the blank group with nine rats and the modeling group with 27 rats. The rats in the modeling group were administered hypoxanthine solution at 300 mg·kg-1·d-1 and potassium oxonate solution at 250 mg·kg-1·d-1, combined with intra-articular injection of 200 μL monosodium urate (MSU) crystal suspension at 25 g·L-1 into the right ankle joint (joint injection once every three days), so as to induce the gouty bone erosion model. After four weeks of modeling, three rats were selected from these two groups to validate the model. The modeled 24 rats were randomly divided into the model group, HSCD group (10.35 g·kg-1·d-1), allopurinol group (20 mg·kg-1·d-1), and inhibitor group (LY294002, 10 mg·kg-1·d-1), with six rats per group. Except for the blank group, rats in all other groups continued to receive hypoxanthine solution at 300 mg·kg-1 and potassium oxonate solution at 250 mg·kg-1 via gavage concurrently with administration to maintain modeling intervention. The rats in the HSCD group and allopurinol group received administration by gavage at the above doses. The rats in the inhibitor group received an intraperitoneal injection at the above dose. The rats in the blank group and model group received saline (10.35 g·kg-1·d-1) by gavage for four consecutive weeks. After administration, ankle joint swelling of the rats in all groups was observed, and the diameters were measured. Bone volume fraction (BV/TV) and bone surface area to bone volume (BS/BV) were observed and quantitatively analyzed by Micro-CT. Histopathological changes in the ankle joint were observed by hematoxylin-eosin (HE) staining and safranin O-fast green staining. The uric acid in the rats' serum was determined by enzyme colorimetry. The levels of inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6 were measured by enzyme-linked immunosorbent assay (ELISA). The protein expressions of receptor activator of nuclear factor-κB ligand (RANKL) and phosphorylated (p)-phosphatidylinositol-3-kinase (PI3K) in ankle joint tissues of rats were detected by immunofluorescence staining. The mRNA levels of the proteins related to the bone erosion, including RANKL, tartrate-resistant acid phosphatase
