Mitomycin C induces apoptosis in human epidural scar fibroblasts after surgical decompression for spinal cord injury

引用

Neural Regeneration Research 2017年第4期12卷 644-653页

Numerous studies have shown that topical application of mitomycin C after surgical decompression effectively reduces scar adhesion. However, the underlying mechanisms remain unclear. In this study, we investigated the effect of mitomycin C on the proliferation and apoptosis of human epidural scar fibroblasts. Human epidural scar fibroblasts were treated with various concentrations of mitomycin C （1, 5, 10, 20, 40 μg/mL） for 12, 24 and 48 hours. Mitomycin C suppressed the growth of these cells in a dose- and time-dependent manner. Mitomycin C upregulated the expression levels of Fas, DR4, DR5, cleaved caspase-8/9, Bax, Bim and cleaved caspase-3 proteins, and it downregulated Bcl-2 and Bcl-xL expression. In addition, inhibitors of caspase-8 and caspase-9 （Z-IETD-FMK and Z-LEHD-FMK, respectively） did not fully inhibit mitomycin C-induced apoptosis. Furthermore, mitomycin C induced endoplasmic reticulum stress by increasing the expression of glucose-regulated protein 78, CAAT/enhancer-binding protein homologous protein （CHOP） and caspase 4 in a dose-dependent manner. Salubrinal significantly inhibited the mitomycin C-induced cell viability loss and apoptosis, and these effects were accompanied by a reduction in CHOP expression. Our results support the hypothesis that mitomycin C induces human epidural scar fibroblast apoptosis, at least in part, via the endoplasmic reticulum stress pathway.

Factors influencing outcomes of intra-aortic balloon counterpulsation in elderly patients

引用

Chinese Medical Journal 2013年第14期126卷 2632-2635页

作者： WU Xue-ping LIU Hong-wei ZHAO xiao-ning cao jian ZHU Ping First Division of Geriatric Cardiology General Hospital of Chinese People's Liberation Army Medical School of Chinese People's Liberation Army Beijing 100853 China

Background Intra-aortic balloon counterpulsation （IABP） is a mechanical cardiac-assist device that is used for cardiac support. There are no published reports about the use of IABP in elderly Chinese patients, especially for those over 80 years old. The aim of this study was to describe the clinical outcomes, influencing factors, and complications in patients 〉80 years old and requiring IABP. Methods We performed a retrospective study of 134 consecutive patients who received IABP therapy. Based on age, we defined two groups; those 〉80 years old and those 〈80 years old. Results The overall mortality was 41.8%. Patients -〉80 years old had higher mortality rates than those 〈80 years old （47.9% vs. 30.2%）. Patients 〉80 years old had fewer successful revascularizations （45.8%） and more pulmonary infections （47.9%） than patients 〈80 years old （60.3% and 30.2%, respectively）; these differences were statistically significant. The most common non-cardiac complication was pulmonary infection. Cardiogenic shock and pulmonary infection were risk factors for all-cause, in-hospital mortality, whereas revascularization success was a negative risk factor for the -〉80 years old patients. Conclusions IABP may be successfully and safely employed in patients 〉80 years old, having severe heart disease, with few complications. Patients 〉80 years old who need IABP therapy are less likely to have a successful revascularization and are more likely to develop pulmonary infections than patients 〈80 years old.

Observation of topological charge transformations in acoustic vortex using passive periodic systems

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 140-147页

Vortex transmutation utilizes a periodic system, which not only enables the alteration of the topological charge(TC) of unstable input vortices but also facilitates their transformation into stable structures. This approach is crucial for investigating the characteristics of vortices in various wave systems. Here, we achieve acoustic vortex TC transmutation by employing a welldesigned dual-structured plate external system(DPES). The interactions between the acoustic vortex and the finite-order discrete rotational symmetry lead to the transformation of its topological charge when complete rotational symmetry is broken to Nthorder discrete symmetry. Our results experimentally demonstrate the acoustic vortex TC transmutation based on passive artificial structures, enabling numerous applications in particle manipulation and information multiplexing as well as advancing our understanding and control over free-space acoustic vortices.

Enhancement of motor functional recovery in thoracic spinal cord injury: voluntary wheel running versus forced treadmill exercise

Neural Regeneration Research 2025年第3期20卷 836-844页

Spinal cord injury necessitates effective rehabilitation strategies, with exercise therapies showing promise in promoting recovery. This study investigated the impact of rehabilitation exercise on functional recovery and morphological changes following thoracic contusive spinal cord injury. After a 7-day recovery period after spinal cord injury, mice were assigned to either a trained group(10 weeks of voluntary running wheel or forced treadmill exercise) or an untrained group. Bi-weekly assessments revealed that the exercise-trained group, particularly the voluntary wheel exercise subgroup, displayed significantly improved locomotor recovery, more plasticity of dopaminergic and serotonin modulation compared with the untrained group. Additionally, exercise interventions led to gait pattern restoration and enhanced transcranial magnetic motor-evoked potentials. Despite consistent injury areas across groups, exercise training promoted terminal innervation of descending axons. In summary, voluntary wheel exercise shows promise for enhancing outcomes after thoracic contusive spinal cord injury, emphasizing the role of exercise modality in promoting recovery and morphological changes in spinal cord injuries. Our findings will influence future strategies for rehabilitation exercises, restoring functional movement after spinal cord injury.

Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

引用

Journal of Energy Chemistry 2025年第1期100卷 770-778页

作者： xiaoqin Li jian Xiang Lu Qiu xiaohan Chen Yinkun Zhao Yujue Wang Qu Yue Taotao Gao Wenlong Liu Dan xiao Zhaoyu Jin Panpan Li Institute for Advanced Study Chengdu University School of Mechanical Engineering Chengdu University College of Food and Biological Engineering Chengdu University Institute of Fundamental and Frontier Sciences University of Electronic Science and Technology of China College of Materials Science and Engineering Sichuan University

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.
