Current epilepsy prediction methods are not effective in characterizing the multi-domain features of complex long-term electroencephalogram (EEG) data, leading to suboptimal prediction performance. Therefore, this paper proposes a novel multi-scale sparse adaptive convolutional network based on multi-head attention mechanism (MS-SACN-MM) model to effectively characterize the multi-domain features. The model first preprocesses the EEG data, constructs multiple convolutional layers to effectively avoid information overload, and uses a multi-layer perceptron and multi-head attention mechanism to focus the network on critical pre-seizure features. Then, it adopts a focal loss training strategy to alleviate class imbalance and enhance the model's robustness. Experimental results show that on the publicly created dataset (CHB-MIT) by MIT and Boston Children's Hospital, the MS-SACN-MM model achieves a maximum accuracy of 0.999 for seizure prediction 10 ~ 15 minutes in advance. This demonstrates good predictive performance and holds significant importance for early intervention and intelligent clinical management of epilepsy patients.

Huntington's disease (HD) is an inherited neurodegenerative disorder caused by the abnormal expansion of CAG trinucleotide repeats in the Huntingtin gene (HTT) located on chromosome 4. It is transmitted in an autosomal dominant manner and is characterized by motor dysfunction, cognitive decline, and emotional disturbances. To date, there are no curative treatments for HD have been developed; current therapeutic approaches focus on symptom relief and comprehensive care through coordinated pharmacological and nonpharmacological methods to manage the diverse phenotypes of the disease. International clinical guidelines for the treatment of HD are continually being revised in an effort to enhance care within a multidisciplinary framework. Additionally, innovative gene and cell therapy strategies are being actively researched and developed to address the complexities of the disorder and improve treatment outcomes. This review endeavours to elucidate the current and emerging gene and cell therapy strategies for HD, offering a detailed insight into the complexities of the disorder and looking forward to future treatment paradigms. Considering the complexity of the underlying mechanisms driving HD, a synergistic treatment strategy that integrates various factors-such as distinct cell types, epigenetic patterns, genetic components, and methods to improve the cerebral microenvironment-may significantly enhance therapeutic outcomes. In the future, we eagerly anticipate ongoing innovations in interdisciplinary research that will bring profound advancements and refinements in the treatment of HD.

OBJECTIVE: This study aimed to reexplore minimum iodine excretion and to build a dietary iodine recommendation for Chinese adults using the obligatory iodine loss hypothesis. METHODS: Data from 171 Chinese adults (19-21 years old) were collected and analyzed based on three balance studies in Shenzhen, Yinchuan, and Changzhi. The single exponential equation was accordingly used to simulate the trajectory of 24 h urinary iodine excretion as the low iodine experimental diets offered (iodine intake: 11-26 μg/day) and to further deduce the dietary reference intakes (DRIs) for iodine, including estimated average requirement (EAR) and recommended nutrient intake (RNI). RESULTS: The minimum iodine excretion was estimated as 57, 58, and 51 μg/day in three balance studies, respectively. Moreover, it was further suggested as 57, 58, and 51 μg/day for iodine EAR, and 80, 81, and 71 μg/day for iodine RNI or expressed as 1.42, 1.41, and 1.20 μg/(day·kg) of body weight. CONCLUSION The iodine DRIs for Chinese adults were established based on the obligatory iodine loss hypothesis, which provides scientific support for the amendment of nutrient requirements.

Objective To explore the correlation between the pathogenesis of toxins damaging liver collateral and the incidence of type 2 diabetes mellitus(T2DM)based on the theory of five circuits and six qi.Methods A total of 986 patients with T2DM treated in the Department of Endocrinology and Metabolism at the Affiliated Hospital of Changchun University of Chinese Medicine from February 2019 to October 2023 were selected as the study subjects.The influences of circuit and qi indicators in the theory of five circuits and six qi on the constitutional characteristics of T2DM patients and the role of pathogenesis of toxins damaging liver collateral in the incidence of T2DM were investigated.Results(1)The five-circuit and six-qi analysis showed that the yearly circuit and sitian/zaiquan conditions had no significant effect on the constitutional characteristics of patients with T2DM(P＞0.05).However,dominant circuit,guest circuit,dominant qi and guest qi significantly influenced the constitutional characteristics of patients with T2DM(P＜0.05).For the distribution of circuit-qi indicators at birth among the 986 patients,dominant circuit was predominated by the terminal circuit of taiyang cold-water,guest circuit was characterized by deficient wood circuit or excessive water circuit,dominant qi was predominated by yangming dry-metal,and guest qi was characterized by taiyin damp-earth.(2)The correlation between the pathogenesis of toxins damaging liver collateral and the incidence of T2DM through comparative analysis revealed that the conveying and dispersing function of the liver plays a leading role in maintaining the body's yin-yang balance and ensuring free movement of qi,indicating that the critical role of toxins damaging liver collateral is the key to the incidence of diabetes.Conclusion Circuit-qi indicators have a certain influence on the constitutional characteristics of T2DM patients.The circuit-qi features at birth of the individuals prone to T2DM are as follows:dominant circuit predominated by the terminal circuit of taiyang cold-water,guest circuit characterized by deficient wood circuit or excessive water circuit,dominant qi being yangming dry-metal,and guest qi being taiyin damp-earth.Pathogenesis of toxins damaging liver collateral is closely related to the incidence of T2DM.Therefore,in treatment,the regulatory role of the liver should be emphasized,and liver-soothing herbs should be used based on syndrome differentiation,aiming for holistic treatment of the physique and the spirit and enhancing the therapeutic efficacy.The exploration will provide a new perspective and approach for the treatment of T2DM.
