ObjectiveTo explore the effects and mechanism of the modified Danggui Yinzi on "itch-anxiety" model rats of chronic urticaria (CU). MethodsThe 36 SPF-grade 6-8-week-old female SD rats were randomly divided into a blank control group,a model group,a positive control group,a low-dose modified Danggui Yinzi group,a medium-dose modified Danggui Yinzi group,and a high-dose modified Danggui Yinzi group. A "itch-anxiety" model was established by intraperitoneal injection of a suspension of sodium chloride and aluminum hydroxide and ovalbumin,combined with chronic unpredictable emotional stress stimulation. After successful modeling,rats in each group were administered drugs by gavage. The positive control group was given intragastric administration of the drug solutions of cetirizine and fluoxetine (2.08 mg·kg-1·d-1 fluoxetine, 2 mg·kg-1·d-1 cetirizine), the low-,medium-,and high-dose modified Danggui Yinzi groups were administered traditional Chinese medicine at 1.44,2.88, 5.76 g·kg-1, respectively,while the blank control group and model group were given an equal volume of normal saline. All interventions lasted for 15 days. Behavioral changes were evaluated by the elevated plus-maze test (detecting the percentage of entries into the open arms (OE%),the percentage of time spent in the open arms (OT%),and the total number of entries into the open and closed arms (TNE)),the open-field test (detecting total activity,average movement speed,and latency to enter the central area),and scratching behavior observation. Pathological changes of skin tissues were observed by hematoxylin-eosin (HE) staining and toluidine blue staining,while those of amygdala tissues were observed by HE staining,Nissl staining,and immunofluorescence detection of ionized calcium-binding adapter molecule-1 (Iba-1). The content of immunoglobulin E (IgE),interleukin-33 (IL-33),histamine in serum and glutamate in the amygdala was detected by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the protein expression of striatal-enriched protein tyrosine phosphatase (STEP),N-methyl-D-aspartate receptor subunit 2B (NR2B), calmodulin-dependent protein kinase Ⅱ (CaMKⅡ),phosphorylated CaMKⅡ (p-CaMKⅡ),mitogen-activated protein kinase (MAPK),phosphorylated MAPK (p-MAPK),nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB),phosphorylated NF-κB (p-NF-κB),and postsynaptic density protein-95 (PSD-95) in the amygdala. ResultsCompared with the blank control group,the model group rats showed obvious anxiety-like behaviors (decreased OE%,OT%,and TNE,reduced total activity,slower average movement speed,and prolonged latency to enter the central area),increased scratching times,obvious skin inflammation and mast cell degranulation,severe amygdala tissue damage,increased glutamate content in the amygdala,and elevated levels of IgE and IL-33 in serum. The expression of STEP,NF-κB,p-NF-κB,NR2B,MAPK,p-MAPK,CaMKⅡ,and p-CaMKⅡ proteins in the amygdala increased,while the expression of PSD-95 protein decreased (P<0.05). Compared with the model group,the modified Danggui Yinzi group of each dose had increased OE%,OT%,TNE,total activity,and average movement speed,shortened latency to enter the central area, reduced scratching times,alleviated skin inflammation and mast cell degranulation,relieved amygdala tissue damage,decreased glutamate content in the amygdala,and reduced levels of IgE and IL-33 in serum. Moreover,compared with the model group,the low -,medium-,and high-dose modified Danggui Yinzi groups showed decreased expression levels of STEP,NF-κB,p-NF-κB,NR2B,MAPK,p-MAPK,CaMKⅡ,and p-CaMKⅡ proteins in the amygdala,and increased expression of PSD-95 protein. There was a significant dose-effect relationship,with the high-dose group showing the most significant regulatory effect (P<0.05). ConclusionThe modified Danggui Yinzi has a therapeutic effect on "itch-anxiety" model rats of CU. Its mechanism may be related to regulating glutamate metabolism in the amygdala,modulating the STEP/NR2B/CaMKⅡ/MAPK/NF-κB pathway,and regulating the expression of PSD-95.

This paper has summarized current studies on retinitis pigmentosa (RP) from two perspectives, which were disease mechanism insights from western medicine, and etiology, pathogenesis and therapeutic principles in traditional Chinese medicine (TCM). From the perspective of western medicine, the understanding of RP has evolved from an early single-factor explanation focusing on pathogenic gene mutations to a more comprehensive, multifactorial model involving genetic abnormalities, photoreceptor cell degeneration, retinal pigment epithelium dysfunction, oxidative stress, inflammatory responses, microenvironmental imbalance, and vascular insufficiency. In TCM, RP is considered to be a disorder manifested in the eyes but rooted in dysfunction of the zang-fu (脏腑) organs. Its pathogenesis is primarily associated with congenital insufficiency, liver-kidney depletion, impaired spleen function of transportation and transformation, and stasis obstructing the meridians. The core pathological mechanism can be summarized as "deficiency complicated by stasis", emphasizing holistic imbalance, dynamic disease progression, and syndrome differentiation and treatment. The differences and complementarities between the two medical systems in understanding disease progression are further discussed. RP is proposed to be more appropriately regarded as a complex disease characterized by long-term progression, stage-dependent evolution, and persistent decompensation. Western medicine contributes to elucidating the molecular mechanisms underlying RP and provides the foundation for targeted therapeutic interventions, whereas TCM offers a holistic perspective for understanding disease evolution through the assessment of overall functional status, disease-stage stratification, and long-term syndrome-based regulation.

Objective To investigate the status and predictive factors of future acute exacerbation of asthma in adults. Methods Adult patients with asthma who were admitted to the hospital from March 2023 to July 2025 were selected. Based on the acute exacerbation status after follow-up, the patients were categorized into acute exacerbation group (n=107) and control group (n=245). The clinical data, pulmonary function [peak expiratory flow (PEF) and forced expiratory volume in the 1st second/forced vital capacity (FEV1/FVC)] and health status [asthma control questionnaire (ACQ), Morisky medication adherence scale (MMAS-8), short form 36-item health survey (SF-36)] of the study subjects were collected. The correlation between the indicators and acute exacerbation was explored by logistic regression analysis, and the predictive efficiency was evaluated by ROC curve. Results The age, smoking history, asthma course, allergen exposure and ACQ in the acute exacerbation group were higher than those in the control group, while the average monthly family income, glucocorticoid treatment, PEF, FEV1/FVC, MMAS-8 and SF-36 were lower (P<0.05). Multivariate logistic regression suggested that ACQ score, glucocorticoid treatment, MMAS-8 score, FEV1/FVC, PEF and smoking history were the influencing factors of acute asthma exacerbation (P<0.05). ROC analysis revealed that the diagnostic efficiency of combined prediction was the highest (AUC=0.965), with sensitivity of 0.944 and specificity of 0.857 (P<0.05). Conclusion It is necessary to pay more attention to the medication compliance and asthma control level of patients, and integrate multi-dimensional information such as smoking history, pulmonary function and treatment conditions to accurately identify patients with high-risk acute exacerbation and implement targeted intervention measures.
