Electroacupuncture alleviates zymosan-induced colorectal hypersensitivity

Journal of Traditional Chinese Medicine 2025年第1期45卷 32-38页

OBJECTIVE: this study to investigate the mechanism underlying the electroacupuncture(EA) alleviates colorectal hypersensitivity, a feature of irritable bowel syndrome(IBS). METHODS: The colorectal hypersensitivity model was established by treating mice with zymosan. Electrophysiological techniques, Western blotting and immunofluorescence staining were used to detect the changes of the sensitive state of the colorectum and the response in spinal ganglion and spinal cord after acupuncture intervention. RESULTS: colorectal distension studies revealed that repetitive applied electroacupuncture treatment on mice could significant alleviates colorectal intensity. Western blotting studies with nerve growth factor(NGF) in the colorectum, substance P(SP) in the spinal ganglion, protein kinase C gamma(PKCγ) in the spinal cord, and transient receptor potential vanilloid 1(TRPV1) showed that electroacupuncture suppressed zymosan-induced expression of TRPV1, NGF and SP in multiple tissues. Immunofluorescence labeling results showed that EA attenuated the expression of NGF in the colorectum, SP in the spinal ganglion, PKCγ in the spinal cord, and TRPV1 in all three tissues in zymosan-treated mice. Moreover, the number of neurons double-positive for TRPV1/Isolectin B4(IB4) and TRPV1/Neurofilament(NF) 200 was increased in the spinal ganglion. CONCLUSION: these results provide molecular-level evidence that EA alleviates zymosan-induced colorectal hypersensitivity by altering the expression of pain-associated proteins in the colorectum and spinal cord. EA has a potential to be therapeutic intervention option for IBS treatment.

A nitrogen-rich halogen-bonded organic framework (XOF) for efficient iodine capture and security printing

The escalating utilization of nuclear energy and nuclear medicine raises concerns about the environmental impact of radioactive iodine, necessitating the development of effective iodine adsorbents, especially under a real-world scenario with extremely low iodine concentration and elevated temperature. Herein, we have presented the construction of a nitrogen-abundant two-dimensional (2D) halogen-bonded organic framework, XOF-TNP, characterized by exceptional crystallinity, thermal stability, and nitrogen-rich structures. XOF-TNP exhibits strong binding to iodine, thanks to the fact that iodine can be pre-enriched into the framework through N & ctdot;I interactions. The nitrogen-rich framework and I+ synergistically have extremely high binding force to iodine, enabling the rapid and efficient capture of iodine in both vapor and solution phases, with significant recyclability. Further flow-through adsorption experiments using an XOF-TNP-packed column achieve 99% iodine removal from hexane and aqueous solutions, surpassing traditional activated carbon. This highlights its potential for environmental remediation. XOF-TNP enables the development of a novel rewritable security paper, utilizing its iodine adsorption properties to encrypt and decrypt QR codes. This research expands the application scope of halogen-bonded organic frameworks, providing insights into the design of materials for environmental remediation and security applications.

Enhanced Tube-Based Event-Triggered Stochastic Model Predictive Control With Additive Uncertainties

IEEE/CAA Journal of Automatica Sinica 2025年第3期12卷 596-605页

This paper proposes an event-triggered stochastic model predictive control for discrete-time linear time-invariant(LTI) systems under additive stochastic disturbances. It first constructs a probabilistic invariant set and a probabilistic reachable set based on the priori knowledge of system *** with enhanced robust tubes, the chance constraints are then formulated into a deterministic form. To alleviate the online computational burden, a novel event-triggered stochastic model predictive control is developed, where the triggering condition is designed based on the past and future optimal trajectory tracking errors in order to achieve a good trade-off between system resource utilization and control performance. Two triggering parameters σ and γ are used to adjust the frequency of solving the optimization problem. The probabilistic feasibility and stability of the system under the event-triggered mechanism are also examined. Finally, numerical studies on the control of a heating, ventilation, and air conditioning(HVAC) system confirm the efficacy of the proposed control.
