Sleep is an instinctive behavior alternating awakening state, sleep entails many active processes occurring at the cellular, circuit and organismal levels. The function of sleep is to restore cellular energy, enhance immunity, promote growth and development, consolidate learning and memory to ensure normal life activities. However, with the increasing of social pressure involved in work and life, the incidence of sleep disorders (SD) is increasing year by year. In the short term, sleep disorders lead to impaired memory and attention; in the longer term, it produces neurological dysfunction or even death. There are many ways to directly or indirectly contribute to sleep disorder and keep the hormones, including pharmacological alternative treatments, light therapy and stimulus control therapy. Exercise is also an effective and healthy therapeutic strategy for improving sleep. The intensities, time periods, and different types of exercise have different health benefits for sleep, which can be found through indicators such as sleep quality, sleep efficiency and total sleep time. So it is more and more important to analyze the mechanism and find effective regulation targets during sleep disorder through exercise. Dopamine (DA) is an important neurotransmitter in the nervous system, which not only participates in action initiation, movement regulation and emotion regulation, but also plays a key role in the steady-state remodeling of sleep-awakening state transition. Appreciable evidence shows that sleep disorder on humans and rodents evokes anomalies in the dopaminergic signaling, which are also implicated in the development of psychiatric illnesses such as schizophrenia or substance abuse. Experiments have shown that DA in different neural pathways plays different regulatory roles in sleep behavior, we found that increasing evidence from rodent studies revealed a role for ventral tegmental area DA neurons in regulating sleep-wake patterns. DA signal transduction and neurotransmitter release patterns have complex interactions with behavioral regulation. In addition, experiments have shown that exercise causes changes in DA homeostasis in the brain, which may regulate sleep through different mechanisms, including cAMP response element binding protein signal transduction, changes in the circadian rhythm of biological clock genes, and interactions with endogenous substances such as adenosine, which affect neuronal structure and play a neuroprotective role. This review aims to introduce the regulatory effects of exercise on sleep disorder, especially the regulatory mechanism of DA in this process. The analysis of intracerebral DA signals also requires support from neurophysiological and chemical techniques. Our laboratory has established and developed an in vivo brain neurochemical analysis platform, which provides support for future research on the regulation of sleep-wake cycles by movement. We hope it can provide theoretical reference for the formulation of exercise prescription for clinical sleep disorder and give some advice to the combined intervention of drugs and exercise.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

【Objective】 To explore the feasibility of using autologous platelet-rich plasma (PRP) in the treatment of deep second-degree burns complicated with wound infection. 【Methods】 A retrospective analysis was conducted on the treatment process of a patient with deep second-degree burns and bacterial infection on the wound using autologous PRP. Clinical treatment highlights and outpatient follow-up were combined to discuss the feasibility and clinical effects of using autologous PRP in the treatment of burn wounds complicated with infection. 【Results】 The patient had a deep second-degree burn with a coagulase-negative Staphylococcus infection on the left lower limb. After one week of conventional wound dressing and antibiotic treatment, the patient's body temperature returned to normal. However, wound healing was slow and yellow secretion persisted. Subsequently, the burn wound was treated combined with topical autologous PRP. The wound pain score gradually decreased from 8 to 1. After 2 weeks, the bacterial culture of the wound secretion was negative, and the wound healed completely after 18 days. The wound scar score decreased from 5 to 2 at 1, 3 and 6 months after PRP treatment, and no obvious scar formation was observed. In the course of PRP treatment, there were no adverse reactions such as increased wound inflammation, abnormal blood routine and liver and kidney function test results. 【Conclusion】 For deep second-degree burn patients with localized wound bacterial infections who either refuse surgery or are not suitable for surgery, autologous PRP is a safer alternative that can effectively promote tissue regeneration and wound healing. The patient in this case achieved a curative effect in a short period of time.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

Objective:To understand the loss to follow-up of children born to pregnant women with HIV infection (HIV-exposed children) and analyze its influencing factors in China in 2019.Methods:The data were collected from the follow-up records of pregnant women with HIV infection and their children reported by the national "Management Information System for the Prevention of HIV, syphilis and Hepatitis B Mother-to-Child Transmission" in 2019. HIV-exposed children were defined as those who were not followed up after birth or who were not followed up at 18 months of age and who were not followed up at 21 months of age. The univariate and multivariate influencing factors of loss to follow-up of children born to HIV-infected pregnant women were analyzed by χ2 test and logistic regression model. SPSS 25.0 software was used for statistical analysis. Results:The number of HIV-infected pregnant women was 5 039, the number of live-born children was 5 035, the number of loss to follow-up children within 18 months of age was 283, and the loss to follow-up rate children was 5.62%(283/5 035). The results of multivariate logistic regression analysis showed that the rate of loss to follow-up of exposed children born to pregnant women who worked as farmers (animal husbandry and fishery) (a OR=0.34, 95% CI: 0.22-0.53), unmarried (a OR=0.47, 95% CI: 0.24-0.93), first marriage (a OR=0.38, 95% CI: 0.22-0.67), remarriage (a OR=0.36, 95% CI: 0.20-0.67) and cohabiting (a OR=0.47, 95% CI: 0.23-0.97), and knew they had HIV infection before this pregnancy (a OR=0.53, 95% CI: 0.40-0.70) was lower. Han nationality (a OR=1.52, 95% CI: 1.09-2.13), primary school (a OR=2.06, 95% CI: 1.10-3.89) and junior middle school (a OR=1.81, 95% CI: 1.03-3.17) educational level, non-use of antiviral drugs (a OR=6.21, 95% CI: 4.32-8.93) and delivery in township (street) level midwifery institutions (a OR=5.72, 95% CI: 1.61-20.27) had higher rates of loss to follow-up among infants born to HIV-infected pregnant women. Conclusions:HIV-exposed children still have a specific rate of loss to follow-up in China in 2019. In order to further reduce the rate of loss to follow-up, it is of great significance to improve the detection rate of HIV before pregnancy and the rate of antiviral drugs used in pregnant women with HIV infection, which is of great significance for the effective implementation of comprehensive intervention measures of prevention of mother-to-child transmission of HIV.
