Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as 131I,177Lu, or 18F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, 18F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Activation of nuclear factor erythroid 2-related factor 2(Nrf2)by Kelch-like ECH-associated protein 1(Keap1)alkylation plays a central role in anti-inflammatory therapy.However,activators of Nrf2 through alkylation of Keap1-Kelch domain have not been identified.Deoxynyboquinone(DNQ)is a natural small molecule discovered from marine actinomycetes.The current study was designed to investigate the anti-inflammatory effects and molecular mechanisms of DNQ via alkylation of Keap1.DNQ exhibited signif-icant anti-inflammatory properties both in vitro and in vivo.The pharmacophore responsible for the anti-inflammatory properties of DNQ was determined to be the α,β-unsaturated amides moieties by a chemical reaction between DNQ and N-acetylcysteine.DNQ exerted anti-inflammatory effects through activation of Nrf2/ARE pathway.Keap1 was demonstrated to be the direct target of DNQ and bound with DNQ through conjugate addition reaction involving alkylation.The specific alkylation site of DNQ on Keap1 for Nrf2 activation was elucidated with a synthesized probe in conjunction with liquid chromatography-tandem mass spectrometry.DNQ triggered the ubiquitination and subsequent degra-dation of Keap1 by alkylation of the cysteine residue 489(Cys489)on Keap1-Kelch domain,ultimately enabling the activation of Nrf2.Our findings revealed that DNQ exhibited potent anti-inflammatory capacity through α,β-unsaturated amides moieties active group which specifically activated Nrf2 signal pathway via alkylation/ubiquitination of Keap1-Kelch domain,suggesting the potential values of targeting Cys489 on Keap1-Kelch domain by DNQ-like small molecules in inflammatory therapies.

Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

OBJECTIVES:
To observe the changes of skin blood flow perfusion at Waiguan (TE 5) caused by mild moxibustion with moxa stick and infrared mild moxibustion using laser speckle contrast imaging technology, and to compare the microcirculatory effect during and after both moxibustion methods and explore the dose-response relationship of moxibustion.
METHODS:
Twenty-four healthy participants were treated with mild moxibustion with moxa stick and infrared mild moxibustion at left Waiguan (TE 5). The record started when the skin temperature reached (44±1) °C, and both moxibustion methods were provided within this temperature range. The 20-minute moxibustion process was divided into four stages (5, 10, 15, and 20 min) using interpolation method, and each participant completed eight interventions with a minimum 24-hour interval between different interventions. The skin surface temperature of the left Waiguan (TE 5) was monitored when both moxibustion interventions were given for 10 min using a TES1306 thermocouple thermometer. The skin microcirculatory blood perfusion units (MBPU) of left Waiguan (TE 5) was measured using a PSIN-01087 laser speckle blood flow imager 1 min before moxibustion, at 5, 10, 15, 20 min during moxibustion and continuously for 20 min after moxibustion in each intervention.
RESULTS:
The skin surface temperature of the left Waiguan (TE 5) remained within the range of (44±1) °C during both moxibustion methods, with no statistically significant difference (P>0.05). Compared with that before moxibustion, the MBPU of the left Waiguan (TE 5) was increased significantly at 5, 10, 15, and 20 min of both moxibustion methods (P<0.05, P<0.01). Compared with moxibustion for 10, 15 and 20 min, the MBPU of the left Waiguan (TE 5) of moxibustion for 5 min was lower in both moxibustion methods (P<0.01). For both moxibustion methods with the same moxibustion course, the MBPU of the left Waiguan (TE 5) 20 min after intervention was significantly higher than that at 1 min before moxibustion (P<0.001), and there was no significant difference in MBPU between 1 min before moxibustion and 20 min after moxibustion among different groups (P>0.05). Within the same moxibustion method, the MBPU of the left Waiguan (TE 5) 20 min after moxibustion with the intervention of 5 min was lower compared to that of 10, 15, and 20 min of moxibustion (P<0.001), with no significant differences between 10, 15, and 20 min of moxibustion (P>0.05).
CONCLUSIONS
When controlling the skin temperature at Waiguan (TE 5) within (44±1) °C, infrared mild moxibustion has similar effects on skin microcirculatory blood perfusion as traditional mild moxibustion with moxa sticks. From a dose-response perspective, microcirculation reached a stable state after 10 min of moxibustion, and moxibustion interventions lasting for more than 10 min shows better therapeutic effects.
