摘要:
<jats:title>ABSTRACT</jats:title><jats:p>During a long‐duration manned spaceflight mission, such as flying to Mars and beyond, all crew members will spend a long period in an independent spacecraft with closed‐loop bioregenerative life‐support systems. Saving resources and reducing medical risks, particularly in mental heath, are key technology gaps hampering human expedition into deep space. In the 1960s, several scientists proposed that an induced state of suppressed metabolism in humans, which mimics ‘hibernation’, could be an ideal solution to cope with many issues during spaceflight. In recent years, with the introduction of specific methods, it is becoming more feasible to induce an artificial hibernation‐like state (synthetic torpor) in non‐hibernating species. Natural torpor is a fascinating, yet enigmatic, physiological process in which metabolic rate (MR), body core temperature (<jats:italic>T</jats:italic><jats:sub>b</jats:sub>) and behavioural activity are reduced to save energy during harsh seasonal conditions. It employs a complex central neural network to orchestrate a homeostatic state of hypometabolism, hypothermia and hypoactivity in response to environmental challenges. The anatomical and functional connections within the central nervous system (CNS) lie at the heart of controlling synthetic torpor. Although progress has been made, the precise mechanisms underlying the active regulation of the torpor–arousal transition, and their profound influence on neural function and behaviour, which are critical concerns for safe and reversible human torpor, remain poorly understood. In this review, we place particular emphasis on elaborating the central nervous mechanism orchestrating the torpor–arousal transition in both non‐flying hibernating mammals and non‐hibernating species, and aim to provide translational insights into long‐duration manned spaceflight. In addition, identifying difficulties and challenges ahead will underscore important concerns in engineering synthetic torpor in humans. We believe that synthetic torpor may not be the only option for manned long‐duration spaceflight, but it is the most achievable solution in the foreseeable future. Translating the available knowledge from natural torpor research will not only benefit manned spaceflight, but also many clinical settings attempting to manipulate energy metabolism and neurobehavioural functions.</jats:p>
摘要:
Chronic infection is considered a risk factor for atherosclerosis. The link between infectious agents and atherosclerosis is manifested by the presence of infection-induced pyroptotic cells in atherosclerotic lesions. Pyroptosis is an inflammatory form of programmed cell death that occurs most frequently upon infection. However, inflammation is not the only cause by which pyroptosis involved in atherosclerosis. During pyroptosis, a large amount of microparticles are released from pyroptotic cells, which not only transfer inflammatory mediators to arterial vessel, but also mediate the interaction between a variety of cells, leading to endothelial injury, macrophage infiltration, vascular smooth muscle cell migration and proliferation, thereby accelerating atherosclerosis. Thus, we proposed hypothesis that pyroptotic cell-derived microparticle is an atherogenic factor in infectious diseases.

摘要:
<jats:p>Cardiovascular disease is one of the main human health risks, and the incidence is increasing. Salidroside is an important bioactive component of <jats:italic>Rhodiola rosea</jats:italic> L., which is used to treat Alzheimer’s disease, tumor, depression, and other diseases. Recent studies have shown that salidroside has therapeutic effects, to some degree, in cardiovascular diseases via an antioxidative mechanism. However, evidence-based clinical data supporting the effectiveness of salidroside in the treatment of cardiovascular diseases are limited. In this review, we discuss the effects of salidroside on cardiovascular risk factors and cardiovascular diseases and highlight potential antioxidant therapeutic strategies.</jats:p>

KIF16B;Kinesin;Endocytic trafficking;Cholesterol transport
摘要:
As a member of the kinesin-3 family, kinesin family member 16B (KIF16B) has a characteristic PhoX homology (PX) domain that binds to membranes containing phosphatidylinositol-3-phosphate (PI(3)P) and moves along microtubule filaments to the plus end via a process regulated by coiled coils in the stalk region in various cell types. The physiological function of KIF16B supports the transport of intracellular cargo and the formation of endosomal tubules. Ras-related protein (Rab) coordinates many steps of membrane transport and are involved in the regulation of KIF16B-mediated vesicle trafficking. Data obtained from clinical research suggest that KIF16B has a potential effect on the disease processes in intellectual disability, abnormal lipid metabolism, and tumor brain metastasis. In this review, we summarize recent advances in the structural and physiological characteristics of KIF16B as well as diseases associated with KIF16B disorders, and speculating its role as a potential adaptor for intracellular cholesterol trafficking.

摘要:
In the past, hydrogen sulfide (H2S) was considered as a poisonous gas or waste of the body. Later, researchers found that H2S-producing enzymes exist in mammals. Moreover, their findings indicated that endogenous H2S was associated with the occurrence of many diseases. Therefore, endogenous H2S is able to participate in the regulation of physiological and pathological functions of the body as a gas signaling molecule. In this review, we summarize the regulation mechanism of endogenous H2S on the body, such as proliferation, apoptosis, migration, angiogenesis, as well as vasodilation/vasoconstriction. Furthermore, we also analyze the relationship between H2S and some chronic diseases, including hypoxic pulmonary hypertension, myocardial infarction, ischemic perfusion kidney injury, diabetes, and chronic intestinal diseases. Finally, we discuss dietary restriction and drugs that target for H2S. Hence, H2S is expected to become a potential target for treatment of these chronic diseases.

摘要:
The SREBP2/LDLR pathway is sensitive to cholesterol content in the endoplasmic reticulum (ER), while membrane low-density lipoprotein receptor (LDLR) is influenced by sterol response element binding protein 2 (SREBP2), pro-protein convertase subtilisin/kexin type 9 (PCSK9) and inducible degrader of LDLR (IDOL). LDL-C, one of the risk factors in cardiovascular disease, is cleared through endocytosis recycling of LDLR. Therefore, we propose that a balance between LDLR endocytosis recycling and PCSK9-mediated and IDOL-mediated lysosomal LDLR degradation is responsible for cholesterol homeostasis in the ER. For statins that decrease serum LDL-C levels via cholesterol synthesis inhibition, the mechanism by which the statins increase the membrane LDLR may be regulated by cholesterol homeostasis in the ER.

摘要:
Apelin and its G protein-coupled receptor APJ are specifically expressed in endocrine organs. As well known, the hypothalamus is the regulatory center of endocrine activity, which combined with the pituitary and other gonads form regulatory axes involved in endocrine function. Evidence to date has shown that the apelin/APJ system plays an important role in mediating these axes, such as food intake, acute stress, steroid release, as well as, an anti-depressant-like activity. Here we review the effect of the apelin/APJ system on hypothalamic-pituitary-thyroid, hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes. Although the apelinergic system exerts a positive effect on these axes, there are contradictory reports on the role of apelin in endocrine disease caused by hypothalamic-pituitary disorders. Thus, as research continues to evolve we expect that apelin-related drugs can be used as a treatment for clinical diseases resulting from hypothalamic-pituitary dysfunction.

摘要:
Purpose: To investigate the underlying mechanisms by which Astragalus polysaccharide (APS) relieves the reproductive toxicity induced by phenobarbital (PB) treatment in epileptic rats. Methods: Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay kits were used to quantify cell apoptosis in an epileptic rat model. The weight of sex organs and levels of three reproductive hormones, viz, follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone, were measured in order to evaluate the effect of APS administration on reproductive ability. Concentration, motility, morphology as well as fertilization rate of sperms were analyzed as well. Results: Increase in sex organ weight and decrease in apoptosis were both associated with oral APS treatment. In APS-treated group, FSH, LH, and testosterone levels were raised while concentration, motility and normal morphology of sperm also increased. This was consistent with the observed increase in fertilization rate. In addition, hematoxylin and eosin (HE) staining of the testis was performed in the epileptic rat model showed that the size of cell lumen increased in APS-treated group. All APS-associated phenotypes occurred in a concentration-dependent manner. Conclusion: These data suggest that APS lowers reproductive toxicity in PB-treated epileptic rats by regulating the reproductive hormones, FSH, LH and testosterone, and also by altering the concentration, motility, and morphology of sperm. Thus, APS has a potential treatment for minimizing the side effects of antiepileptic drugs.
