AIM:To investigate the effect of apoptosis stimulation protein 2(ASPP2)on the development of traumatic proliferative vitreoretinopathy(PVR)in a rabbit model.METHODS:A total of 30 New Zealand white rabbits were selected, and the right eyes of all rabbits were inflicted with a scleral penetrating wound of approximately 6 mm. Then rabbits were randomly and evenly divided into experimental and control group. The experimental group received an intravitreal injection of 0.1 mL of ARPE-19 cell suspension transfected with lentivirus-ASPP2, while the control group received an intravitreal injection of 0.1 mL of ARPE-19 cell suspension transfected with negative control lentivirus. At 1, 2, 3, and 4 wk after PVR modeling, a handheld tonometer was used to measure the intraocular pressure. Moreover, fundus photography and ocular ultrasound examination were performed to detect the retinal proliferation. At 4 wk after modeling, hematoxylin-eosin staining was used to observe the morphological retinal changes, and Western blot was used to determine the protein expressions of ASPP2 and the epithelial-mesenchymal transition(EMT)marker Vimentin in the rabbit retinas.RESULTS:At 1, 2, 3, and 4 wk after modeling, there were no significant changes in intraocular pressure within the experimental and control group of rabbit eyes, either before or after PVR modeling, the success rate of PVR modeling in the experimental group was lower than that in the control group(P<0.05), and the retinal proliferation and structural disorder was less severe in the experimental group. At 4 wk after modeling, the retinal protein expression level of ASPP2 in the experimental group was significantly higher than that in the control group(t=3.193, P=0.033), while the Vimentin protein expression level was significantly lower in the experimental group(t=-3.599, P=0.023).CONCLUSION:ASPP2 may be involved in regulating the process of EMT in retinal pigment epithelial cells, thereby delaying the development and progression of traumatic PVR in rabbit eyes.

Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity, and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity, this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine (TCM) herbs that strengthen the spleen, regulate qi, and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation, promoting water-damp metabolism, and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness, internal accumulation of phlegm dampness" and immune dysregulation in obesity, this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

In recent years, traditional Chinese medicine (TCM) has achieved significant progress in the treatment of inflammatory bowel disease (IBD). A comprehensive literature search was conducted covering the period from January 1, 2010, to December 30, 2024, across Chinese databases including China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP China Science and Technology Journal Database, and the Chinese Biomedical Literature Service System, as well as international databases such as PubMed, Web of Science, and Embase. The clinical applications and mechanistic studies of TCM in IBD were systematically reviewed. The current status of TCM research on the etiology and pathogenesis of IBD, innovative clinical practices, and multimodal therapeutic approaches, including Chinese herbal formulas, single herbs or active compounds, acupuncture, herbal retention enema, and acupoint application, were summarized, together with their synergistic effects when combined with western medical treatments. The development and application of Chinese patent medicines for IBD are undergoing a profound transition from efficacy validation to mechanistic exploration. Mechanistic studies on the effects of TCM in IBD mainly focus on regulating gut microbiota homeostasis, repairing the intestinal mucosal barrier, and modulating intestinal immune balance. Furthermore, future research directions for TCM-based IBD management are proposed, including the establishment of TCM diagnostic and treatment models, expanding integrated applications of external and internal TCM therapies, innovating personalized treatment strategies, and advancing drug development. These efforts aim to provide insights for the standardized and precision-oriented development of TCM in the diagnosis and treatment of IBD.

To systematically review randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) intervention in ulcerative colitis (UC), and analyze the characteristics of these studies and their outcome indicators, thereby providing references for the design of future RCTs of TCM intervention in UC and offering evidence supporting the clinical application of TCM in UC. A computerized search was conducted in the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science databases for RCTs of TCM intervention in UC published from January 2021 to August 2024. The risk of bias was assessed, and outcome indicators were qualitatively analyzed. A total of 555 RCTs were included, with a sample size of 44 853 participants. The largest sample size was 218 cases, and the smallest was 28 cases, with most studies focusing on 60-100 participants. Of the 386 RCTs that explicitly reported TCM syndrome types, the top three were large intestine dampness-heat syndrome (31.05%), spleen and kidney yang deficiency syndrome (12.47%), and spleen deficiency with dampness syndrome (9.17%). The interventions, ranked by frequency of use, included internal Chinese medicine compounds/preparations (64.5%), Chinese medicine compounds/preparations with retained enema (18.2%), internal Chinese medicine compounds/preparations + external TCM treatment (5.95%), and external TCM treatment alone (4.86%). The treatment duration was mainly 4-8 weeks (64.86%), with 61 studies (10.99%) reporting follow-up time. A total of 157 outcome indicators were used, with a frequency of 3 460 occurrences, classified into six domains: TCM syndromes and symptoms (346 occurrences, 10%), symptoms/signs (541 occurrences, 15.64%), physical and chemical examinations (2 119 occurrences, 61.24%), quality of life (107 occurrences, 3.09%), long-term prognosis (61 occurrences, 1.76%), and safety events (284 occurrences, 8.21%). The analysis reveals several limitations in the outcome indicators of TCM intervention in UC, including the lack of a basis for sample size calculation, non-standardized TCM syndrome classification, absence of trial design and registration, inadequate blinding and allocation concealment, adherence issues with interventions, imbalanced selection of surrogate and endpoint indicators, inconsistency in the timing of outcome measurements, design issues that require standardization, and ethical and safety concerns. It is recommended that future studies actively construct a set of core indicators for UC that include standardized TCM syndrome classification, clear efficacy evaluation indicators, key endpoint indicators, and reasonable measurement time points. Long-term prognostic impacts, comprehensive assessments of patients' quality of life, and consideration of economic benefits should be emphasized, providing a basis for the clinical practice of TCM in the treatment of UC.

OBJECTIVE To optimize the processing technology of Epimedium koreanum roasted with suet oil and analyze its characteristic chromatogram before and after processing. METHODS The optimal processing technology was optimized by orthogonal experiments with frying power, frying time and medicinal temperature as factors using the comprehensive score of appearance traits (color+odor), alcohol-soluble extract, the contents of icariin and baohuoside Ⅰ as evaluation index, then proceed with verification. The E. koreanum roasted with suet oil was prepared with the optimal technology. The characteristic chromatograms of 15 batches of E. koreanum were established with the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition), and then similarity analysis was also conducted. Clustering analysis, principal component analysis, and orthogonal partial least squares discriminant analysis were used to evaluate the differences in E. koreanum before and after processing. RESULTS The optimal processing technique for E. koreanum roasted with suet oil was as follows: first, heat 4 g of suet oil at a power of 600 W until it melts; next, when the temperature at the bottom of the pan reaches 140 ℃, add 20 g of E. koreanum silk and stir-fry for 6 minutes; finally, remove it and let it cool. Comprehensive score of 3 validation tests was 98.94 points (RSD<3%). The established characteristic chromatogram of E. koreanum and E. koreanum roasted with suet oil were calibrated with 16 and 15 common peaks, respectively. Chromatographic peak 2 was determined to be chlorogenic acid, peak 5 to be chaohuoding A, peak 6 to be chaohuoding B, peak 7 to be chaohuoding C, peak 8 to be icariin, and peak 14 to be baohuoside Ⅰ. The similarities were all greater than 0.9. Results of cluster analysis and principal component analysis showed that E. koreanum and E. koreanum roasted with suet oil were clustered into distinct groups. The results of orthogonal partial least squares discriminant analysis showed that the variable importance projection values for peak 13, peak 15, peak 9, peak 1, peak 8, peak 12, peak 7, and peak 10 were all greater than 1. CONCLUSIONS The study successfully optimized the processing technology of suet oil-roasted E. koreanum. There are significant differences in the characteristic chromatograms of E. koreanum before and after processing. Among them, the chemical components corresponding to peak 13, peak 15, peak 9, peak 1, peak 8, peak 12, peak 7, and peak 10 may be the differential components of E. koreanum before and after processing.

Chronic heart failure (CHF) is the final stage of cardiovascular diseases. It is a complex syndrome, with dyspnea and edema as the main clinical manifestations, and it is characterized by complex disease conditions, difficult cure, and high mortality. Ferroptosis, a new type of programmed cell death, is different from other types of programmed cell death. Ferroptosis is iron-dependent, accompanied by lipid peroxide accumulation and mitochondrial shrinkage, becoming a hot research topic. Studies have confirmed that ferroptosis plays a key role in the occurrence and development of CHF. The regulation of ferroptosis may become a potential target for the treatment of CHF in the future. The theory of Qi deficiency and stagnation refers to the pathological state of original Qi deficiency and abnormal transportation and distribution of Qi, blood, and body fluid, which has guiding significance for revealing the pathogenesis evolution of some chronic diseases. We believe that Qi deficiency and stagnation is a summary of the pathogenesis of ferroptosis in CHF. Deficiency of Qi (heart Qi) is the root cause of CHF, and stagnation (phlegm turbidity and blood stasis) is the branch of this disease. The two influence each other in a vicious circle to promote the development of this disease. Traditional Chinese medicine (TCM) plays an important role in the treatment of CHF, improving the prognosis and quality of life of CHF patients. This paper explores the correlation between the theory of Qi deficiency and stagnation and the mechanism of ferroptosis in CHF. Furthermore, this paper reviews the mechanism of Chinese medicines and compound prescriptions in preventing and treating CHF by regulating ferroptosis according to the principles of replenishing Qi and dredging to remove stagnation, aiming to provide new ideas and methods for the treatment of CHF with TCM.

Sleep is an instinctive behavior alternating awakening state, sleep entails many active processes occurring at the cellular, circuit and organismal levels. The function of sleep is to restore cellular energy, enhance immunity, promote growth and development, consolidate learning and memory to ensure normal life activities. However, with the increasing of social pressure involved in work and life, the incidence of sleep disorders (SD) is increasing year by year. In the short term, sleep disorders lead to impaired memory and attention; in the longer term, it produces neurological dysfunction or even death. There are many ways to directly or indirectly contribute to sleep disorder and keep the hormones, including pharmacological alternative treatments, light therapy and stimulus control therapy. Exercise is also an effective and healthy therapeutic strategy for improving sleep. The intensities, time periods, and different types of exercise have different health benefits for sleep, which can be found through indicators such as sleep quality, sleep efficiency and total sleep time. So it is more and more important to analyze the mechanism and find effective regulation targets during sleep disorder through exercise. Dopamine (DA) is an important neurotransmitter in the nervous system, which not only participates in action initiation, movement regulation and emotion regulation, but also plays a key role in the steady-state remodeling of sleep-awakening state transition. Appreciable evidence shows that sleep disorder on humans and rodents evokes anomalies in the dopaminergic signaling, which are also implicated in the development of psychiatric illnesses such as schizophrenia or substance abuse. Experiments have shown that DA in different neural pathways plays different regulatory roles in sleep behavior, we found that increasing evidence from rodent studies revealed a role for ventral tegmental area DA neurons in regulating sleep-wake patterns. DA signal transduction and neurotransmitter release patterns have complex interactions with behavioral regulation. In addition, experiments have shown that exercise causes changes in DA homeostasis in the brain, which may regulate sleep through different mechanisms, including cAMP response element binding protein signal transduction, changes in the circadian rhythm of biological clock genes, and interactions with endogenous substances such as adenosine, which affect neuronal structure and play a neuroprotective role. This review aims to introduce the regulatory effects of exercise on sleep disorder, especially the regulatory mechanism of DA in this process. The analysis of intracerebral DA signals also requires support from neurophysiological and chemical techniques. Our laboratory has established and developed an in vivo brain neurochemical analysis platform, which provides support for future research on the regulation of sleep-wake cycles by movement. We hope it can provide theoretical reference for the formulation of exercise prescription for clinical sleep disorder and give some advice to the combined intervention of drugs and exercise.
