The liver in the traditional Chinese medicine (TCM) theory of visceral manifestation has rich connotations. Thestructure and function of liver differed from that of liver in modern recognition. Research on TCM theory has partiallyexplained the liver theory. The function of controlling dispersion of liver was associated with neuro-endocrine-immunesystem, liver sinus endothelial function, and metallothionein, etc. While the activity of storing blood of liver related withblood coagulation factors, anticoagulant and so on. The functional interaction between Zang-organ and Fu-organ maycorrelate with the lung-liver axis and liver-intestine axis. The review summarized the modern explanation on liverfunction in TCM and its relationship with Fu-organs to help the development of TCM basic theory in liver function.

Objective:
To investigate the association of sugar sweetened beverage (SSB) consumption with insomnia and depressive symptoms among first grade middle school students from Yunnan Province, so as to provide evidence to guide interventions for the treatment of these symptoms in this population.
Methods:
From October to December 2022, 8 500 firstgrade middle school students from 11 counties in Yunnan Province were selected by cluster random sampling. Depressive symptoms, SSB consumption, and insomnia symptoms among students were evaluated by the Child Depression Scale (CDI), dietary frequency questionnaire, and Insomnia Severity Index (ISI). A Logistic regression model was employed to analyze the relationship between SSB consumption, insomnia, depressive symptoms, and their interaction effects among students.
Results:
The detection rate of depressive symptoms was 28.3%, and having insomnia symptoms ( OR=6.07, 95%CI =5.46-6.75), consuming carbonated beverages ( OR=1.20, 95%CI =1.08-1.34), tea ( OR=1.13, 95%CI =1.02-1.25), energy drinks ( OR=1.36, 95%CI =1.23-1.50), and other beverages ( OR=1.32, 95%CI =1.19-1.45) were positively correlated with depressive symptoms among first grade middle school students ( P < 0.05). Carbonated beverages (additive effect: OR=2.96, 95%CI =2.72-3.22, multiplicative effect: OR=4.75, 95%CI =4.25- 5.32 ), fruit drinks (additive effect: OR=2.61, 95%CI =2.40-2.82; multiplicative effect: OR=4.43, 95%CI =3.94-4.97), tea (additive effect: OR=2.70, 95%CI =2.47-2.89; multiplicative effect: OR=4.34, 95%CI =3.86-4.89), energy drinks (additive effect: OR=2.82, 95%CI =2.61-3.05; multiplicative effect: OR=4.48, 95%CI =3.92-5.12), sweetened milk (additive effect: OR= 2.73, 95%CI =2.06-2.96; multiplicative effect: OR=4.61, 95%CI =4.12-5.17) and other beverages (additive effect: OR= 2.73 , 95%CI =2.53-2.95; multiplicative effect: OR=4.56, 95%CI =4.00-5.20) had both additive and multiplicative effects with insomnia, and increased the risk of depressive symptoms in first grade middle school students ( P <0.01).
Conclusions
The interaction between the consumption of SSB and insomnia symptoms may increase the risk of depressive symptoms among first grade middle school students in Yunnan Province. It is necessary to advocate middle school students to reduce SSB intake, in order to decrease the occurrence of depressive symptoms among this population.

Alpha-particles, which have strong cytotoxicity, could reduce radiation damage to surrounding tissues, and stimulate anti-tumor immune response, so they have good development prospect in cancer treatment. The current researches show that α-emitting radionuclides increase the presentation of major histocompatibility complex-I (MHC-Ⅰ) on tumor cells and induce immunogenic cell death (ICD) to activate immune response mediated by CD8 + T cells. As two methods of α-therapy, α radioimmunotherapy and diffusing α-emitters radiation therapy (DART) further enhance the anti-cancer effect when combined with immunotherapy. The methods of immunotherapy include adoptive cell therapy (ACT), immune checkpoint blockade, neutralization of immunosuppressive cells and immunoadjuvant. This article reviews the characteristics of α-particles for cancer treatment, the mechanism of immune response induced by ionizing radiation (including α-radionuclides) and the related research of α-therapy combined with immunotherapy.
