It is essential to employ efficient measures to prevent the transmission of pathogenic agents during a pandemic. One such method involves using hypochlorous acid (HClO) solution. The oxidative properties of HClO water (HAW) can contribute to its ability to eliminate viral particles. Here, we examined a highly purified slightly acidic hypochlorous acid water (Hp-SA-HAW) obtained from the reverse osmosis membrane treatment of an electrolytically-generated SA-HAW for its anti-viral activity and mode of action on viral proteins. Hp-SA-HAW exhibited broad-spectrum antiviral effects against various viruses, including adenovirus, hepatitis B virus, Japanese encephalitis virus (JEV), and rotavirus. Additionally, Hp-SA-HAW treatment dose-dependently resulted in irreversibly aggregated multimers of the JEV envelope and capsid proteins. However, Hp-SA-HAW treatment had no discernible effect on viral RNA, indicating that Hp-SA HAW acts against amino acids rather than nucleic acids. Furthermore, Hp-SA-HAW substantially reduced the infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including the ancestral variant and other multiple variants. Hp-SA-HAW treatment induced the aggregation of the SARS-CoV-2 spike and nuclear proteins and disrupted the binding of the purified spike protein of SARS-CoV-2 to human ACE2. This study demonstrates that the broad-spectrum virucidal activity of highly purified HClO is attributed to viral protein aggregation of virion via protein oxidation.

Summary

Background: It has been reported that topical hypochlorous acid (HOCl) formulations lead to relief of itch in human patients with atopic dermatitis; however, the specific antipruritic mechanism of action remains unclear.

Objective: To confirm itch relief and reduction of lesions in a mouse model of atopic dermatitis and to elucidate possible HOCl’s mode of action.

Methods: In this study, the effects of topical administration of HOCl hydrogel (0.05%) on atopic dermatitis-like lesions in NC/Nga mice model as well as in vitro effects of HOCl on dorsal root ganglia neurons and mouse bone marrow-derived dendritic cells (mBMDCs) were investigated. NC/Nga mice were sensitized with house dust mite allergen and treated topically with HOCl hydrogel both preventively and therapeutically against established lesions. Allergen challenge was continued during HOCl hydrogel application.

Results: Treatment with HOCl hydrogel prevented the development of lesions and scratching bouts during the whole observation period. When administered after full development of lesions, HOCl reduced lesions and scratching behaviour to a similar extent as a positive control 0.1% betamethasone dipropionate ointment. The reduced inflammatory response by HOCl treatment was demonstrated by reduced secretion of inflammatory cytokines in affected skin tissue from NC/Nga mice. In addition, HOCl significantly reduced IL-12 production in mBMDC. The diminished scratching behaviour was confirmed by impaired response to several pruritogens in dorsal root ganglia neurons excised from NC/Nga mice after termination of the studies. The response to the stimuli was also reduced by pre-incubation of sensory neurons from untreated BALB/c mice with 0.0001% HOCl. Conclusions and Clinical Relevance: These data indicate a direct reduction in sensory response by HOCl, leading to significantly reduced itch and inflammation in vivo.

【摘要】经动脉介入治疗（TAI）应用于肝细胞癌（HCC），主要包括经动脉化疗栓塞（TACE）、经动脉栓塞（TAE）、肝动脉灌注化疗（HAIC）和选择性内放射治疗（SIRT）。TACE是治疗不可切除HCC的首选方法，中国医师协会介入医师分会（CCI）分别于2018、2021和2023年制订并更新了《中国肝细胞癌经动脉化疗栓塞（TACE）治疗临床实践指南》，为规范我国 TACE 临床实践发挥了重要作用。近年来，HAIC、SIRT在国内的应用日趋广泛并不断规范。随着TAI技术的进步、治疗理念的更新以及近年来高级别循证医学证据的出现，CCI在既往指南内容基础上，整合TACE、HAIC、SIRT内容并更新颁布《中国肝细胞癌经动脉介入治疗临床实践指南（2026版）》。本指南以最新循证医学证据为基础，结合我国临床实践，涵盖了TAI应用于HCC治疗的新进展，从临床诊断标准与分期、患者适应证与禁忌证、操作流程及要求、围手术期处理、常见并发症及处理、随访及疗效评价、联合治疗、质量控制及热点和展望等方面阐述，旨在进一步规范TAI在HCC治疗中的应用。

【Abstract】 Transarterial interventions (TAI) for hepatocellular carcinoma (HCC) include transarterial chemoembolization (TACE), transarterial embolization (TAE), hepatic arterial infusion chemotherapy (HAIC), and selective internal radiation therapy (SIRT). TACE remains the first‑line treatment for unresectable HCC. Chinese College of Interventionalists (CCI) previously issued and updated the Chinese Clinical Practice Guidelines of TACE for HCC in 2018, 2021, and 2023, which have played a pivotal role in standardizing TACE procedures in China. In recent years, the application of HAIC and SIRT has become increasingly widespread and standardized in China. With the continuous advancement of TAI techniques, the evolution of therapeutic concepts, and the emergence of high‑level evidence, CCI has comprehensively revised and expanded its previous guidelines. The updated Chinese clinical practice guidelines for transarterial interventions of hepatocellular carcinoma (2026 edition) now formally incorporates TACE, HAIC, and SIRT as standard treatment modalities. With the aims to further standardize the use of TAI in the management of HCC, this guideline is developed based on the most current evidence‑based medical research, integrates China‑specific clinical practices, and incorporates the latest advancements in TAI for HCC. It elaborates on clinical diagnostic criteria and staging, patient indications and contraindications, operational procedures and requirements, perioperative management, common complications management, follow‑up and efficacy evaluation, combination therapy, quality control, as well as hot topics and prospects.
