Mitochondrial dysfunction in the pathogenesis of acute pancreatitis

引用

Hepatobiliary & Pancreatic Diseases International 2025年第1期24卷 76-83页

作者： Xia Chen Rui Zhong Bing Hu Department of Gastroenterology and Hepatology West China HospitalSichuan UniversityChengdu 610041China Department of Gastroenterology Clinical Medical College and The First Affiliated Hospital of Chengdu Medical CollegeChengdu 610500China

The mechanism of cell damage during acute pancreatitis (AP) has not been fully elucidated, and there is still a lack of specific or effective treatments. Increasing evidence has implicated mitochondrial dysfunction as a key event in the pathophysiology of AP. Mitochondrial dysfunction is closely related to calcium (Ca^(2+)) overload, intracellular adenosine triphosphate depletion, mitochondrial permeability transition pore openings, loss of mitochondrial membrane potential, mitophagy damage and inflammatory responses. Mitochondrial dysfunction is an early triggering event in the initiation and development of AP,and this organelle damage may precede the release of inflammatory cytokines, intracellular trypsin activation and vacuole formation of pancreatic acinar cells. This review provides further insight into the role of mitochondria in both physiological and pathophysiological aspects of AP, aiming to improve our understanding of the underlying mechanism which may lead to the development of therapeutic and preventive strategies for AP.

Protective effect of lappaconitine on Freund's complete adjuvant-induced arthritis exerted through P2X7 receptor-mediated regulation of M1/M2 balance in rats

引用

Journal of Traditional Chinese Medicine 2025年第1期45卷 39-48页

作者： ZHANG Pengqiang FENG Qi HUANG Weiyan OU Shan School of Medical and Life Sciences Chengdu University of Traditional Chinese Medicine Department of Anesthesiology Chengdu First People's Hospital

OBJECTIVE: to investigate the anti-arthritic effects of lappaconitine（LA） on adjuvant-induced arthritis in Sprague-Dawley rats and its possible involvement in the regulation of M1/M2 macrophage balance through the P2X7 receptor（P2X7r）. METHODS: Rats were immunized with complete Freund's adjuvant and then intraperitoneally administered LA(2, 4, or 8 mg·kg-1·d-1) or methotrexate（0.5 mg/kg per 3 d） for 14 d. The anti-arthritic effects of LA were evaluated through arthritis index（AI） assessment, ankle diameter measurement, and histopathological staining analysis. The analgesic effect of LA on arthritis was measured using mechanical withdrawal threshold testing and gait scoring. The impacts of LA on macrophage polarization, the expression of pro-/anti-inflammatory cytokines and P2X7r were analyzed using quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay, and Western blotting. RESULTS: LA treatment significantly reduced AI scores, paw swelling, joint destruction, and inflammatory cell infiltration, and alleviated arthritis pain. Additionally, LA promoted a balanced M1/M2 ratio by increasing the m RNA expression level of M2 marker arginase 1 and decreasing those of M1 markers inducible nitric oxide synthase and interleukin（IL）-1β in synovial tissues. Furthermore, LA lowered the levels of three M1-related cytokines, namely tumor necrosis factor-α, IL-1β and IL-18, and raised the level of the M2-related cytokine IL-10. Further research showed that treatment with LA inhibited the expression of P2X7r. CONCLUSION: Our findings indicate that the notable therapeutic and analgesic effects of LA on AIA rats are exerted through balancing the M1/M2 ratio, probably via P2X7r.

Chinese Journal of Integrative Medicine 2025年第1期31卷 3-10页

作者： LI Ting LIU Xue-mei YANG Mei WU Yan-qing LIU Wei MAO Bing JIANG Hong-li Division of Pulmonary Medicine Department of Internal MedicineInstitute of Integrated Traditional Chinese and Western MedicineWest China HospitalSichuan UniversityChengdu610041China Department of Pulmonary Diseases State Key Laboratory of Biotherapy of ChinaWest China HospitalSichuan UniversityChengdu610041China

Objective: To evaluate the efficacy and safety of Chinese medicine(CM) Zihua Wenfei Zhisou Granule(ZWZG) in postinfectious cough(PIC) patients with CM syndrome of wind-cold invading Fei(Lung,WCIF). Methods: This is a multicenter, randomized, double-blind, parallel-group, placebo-controlled phase Ⅱclinical trial. PIC patients with WCIF syndrome were recruited from the Respiratory Departments in 6 hospitals across China between March 2019 and December 2020. Eligible patients were randomly assigned to group A(ZWZG-matched placebo 15 g), group B(active ZWZG 15 g), and group C(active ZWZG 10 g plus ZWZGmatched placebo 5 g) in a 1:1:1 ratio. All medications were taken orally 3 times daily for 14 consecutive days. The primary outcomes were cough relief rate and cough disappearance rate. The secondary outcomes included time to cough relief, time to cough disappearance, and changes in cough symptom score(CSS), cough Visual Analog Scale(VAS) value, Cough-Specific Quality of Life Questionnaire(CQLQ) score, and CM syndrome score from baseline(day 0) to post-treatment(day 14). Adverse events(AEs) in each group were recorded. Results: A total of 198 patients were included in the full analysis set(FAS) and safety analysis set(SS), while 183 were enrolled in the per-protocol analysis set(PPS). In the FAS population, the cough relief rate was 47.76%, 90.77% and 84.85%in groups A, B, and C, respectively;while the cough disappearance rate was 31.34%, 72.31% and 68.18%,respectively. The cough relief rates and cough disappearance rates in groups B and C were significantly higher than group A(P<0.0001). Both the median time to cough relief and cough disappearance in groups B and C were shorter than group A(P<0.0001). Compared with group A, groups B and C showed significantly greater improvements from baseline to post-treatment in CSS during daytime and nighttime as well as VAS(P<0.05).There were no significant differences in changes from baseline to post-treatment in CQLQ and CM syndrome
