medical genetics is the newest cutting-edge discipline that focuses on solving medical problems using genetics knowledge and methods. In China, medical genetics research activities initiated from a poor inner basis but a prosperous outer environment. During the 40 years of reform and opening-up policy,Chinese scientists contributed significantly in the field of medical genetics, garnering considerable attention worldwide. In this review, we highlight the significant findings and/or results discovered by Chinese scientists in monogenic diseases, complex diseases, cancer, genetic diagnosis, as well as gene manipulation and gene therapy. Due to these achievements, China is widely recognized to be at the forefront of medical genetics research and development. However, the significant progress and development that has been achieved could not have been accomplished without sufficient funding and a wellconstructed logistics network. The successful implementation of translational and precise medicine sourced from medical genetics will depend on an open ethics policy and intellectual property protection,along with strong support at the national industry level.

Objective To draw a conclusion from the experience on the integrated curriculum of medical genetics and embryonic development set up for the eight-year clinical medicine,and to lay the foundation for its application to the five-year clinical medicine. Methods The advantages and disadvantages of the integrated curriculumof medical genetics and embryonic development were analyzed with the comparative analysis method. And opinions of students of the eight-year clinical medicine on the teaching of the current integrated curriculum were learnt about with questionnaires. Results The current integrated curriculum of medical genetics and embryonic development has basically achieved the goal of simplifying the original teaching contents and the crossing and integration of the related discipline contents,the overall student satisfaction is high. Conclusion The integrated curriculum of medical genetics and embryonic development is helpful for the integral optimization of the medical curriculum framework,which can be expanded to the five-year clinical medicine in the future.

Irisin is a myokine that is generated by cleavage of the membrane protein fibronectin type Ⅲ domain-containing protein 5(FNDC5) in response to physical exercise. Studies reveal that irisin/FNDC5 has neuroprotective functions against Alzheimer's disease, the most common form of dementia in the elderly, by improving cognitive function and reducing amyloid-β and tau pathologies as well as neuroinflammation in cell culture or animal models of Alzheimer's disease. Although current and ongoing studies on irisin/FNDC5 show promising results, further mechanistic studies are required to clarify its potential as a meaningful therapeutic target for alleviating Alzheimer's disease. We recently found that irisin treatment reduces amyloid-β pathology by increasing the activity/levels of amyloid-β-degrading enzyme neprilysin secreted from astrocytes. Herein, we present an overview of irisin/FNDC5's protective roles and mechanisms against Alzheimer's disease.

Introduction:Alzheimer 's disease(AD) is a common neurodegenerative disorder and the primary cause of dementia. Considerable evidence supports the “amyloid hypothesis,” stating that the pathogenesis of AD is primarily caused by the deposition of amyloid-β(Aβ), which drives tau phosphorylation, neuroinflammation, and neurodegeneration in the brain. The amyloid hypothesis is strengthened by the significant and moderate benefit of lecanemab, a humanized antibody through an anti-amyloid mechanism,showing slowed clinical decline(van Dyck et al.,2023). The recent positive results of anti-amyloid trials have brought back focus on the amyloid hypothesis through biochemical, genetic, and pharmacological approaches(Zhang, 2023).

Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders.
