Brain-computer interface (BCI) has high application value in the field of healthcare. However, in practical clinical applications, convenience and system performance should be considered in the use of BCI. Wearable BCIs are generally with high convenience, but their performance in real-life scenario needs to be evaluated. This study proposed a wearable steady-state visual evoked potential (SSVEP)-based BCI system equipped with a small-sized electroencephalogram (EEG) collector and a high-performance training-free decoding algorithm. Ten healthy subjects participated in the test of BCI system under simplified experimental preparation. The results showed that the average classification accuracy of this BCI was 94.10% for 40 targets, and there was no significant difference compared to the dataset collected under the laboratory condition. The system achieved a maximum information transfer rate (ITR) of 115.25 bit/min with 8-channel signal and 98.49 bit/min with 4-channel signal, indicating that the 4-channel solution can be used as an option for the few-channel BCI. Overall, this wearable SSVEP-BCI can achieve good performance in real-life scenario, which helps to promote BCI technology in clinical practice.

OBJECTIVE:
The investigation of the correlation between ecological factors and the genetic characteristics or metabolites of plants offers valuable insights into the regional causes of genetic and metabolic diversity. Here, Gastrodia elata, a medicinal plant, is employed as a model to explore the environmental factors that influence its genetic characteristics and metabolic accumulations.
METHODS:
A total of 23 G. elata populations from six cultispecies and 11 cultivated regions were selected based on the predictions of the global geographic information system. The genetic characteristics of these populations were evaluated using highly polymorphic simple sequence repeat markers. Additionally, the metabolic accumulations and antioxidant capacity of mature tubers were measured employing colorimetry and high performance liquid chromatography (HPLC). Ecological data of each region were obtained from the WorldClim-global climate database and harmonized world soil database. To assess the influence of ecological factors on the genetic characteristics and metabolic profiles of G. elata, Pearson's correlation analysis was conducted.
RESULTS:
Genetic variation among G. elata populations exceeded that within populations. Genetic diverisity, distance and structure manifested regional and species-specific patterns. Metabolic profiling and antioxidant capacity exhibited regional variations. Notably, the Lueyang region demonstrated that a content range of total polysaccharide, total protein, and phenolic glycosides was 9.34%-189.67% higher than the average. Similarly, in the Hubei region, total phenolic content, p-hydroxybenzyl alcohol content, and antioxidant indicators were observed to be higher than the average levels, by 106.57%, 136.47% and 12.50%-91.14%, respectively. Furthermore, ecological factors had a significant comprehensive impact on G. elata genetic characteristics (r > 0.256 and P < 0.05). Multivariate metabolite accumulations in G. elata were influenced by dominant ecological factors. Temperature notably impacted the accumulation of total protein (|r| > 0.528 and P < 0.05). Moisture, encompassing precipitation and soil content, significantly affected the production of phenolic glycosides (|r| > 0.503 and P < 0.05).
CONCLUSION
The genetic characteristics of G. elata manifested regional and species-specific patterns, with the metabolic accumulations and antioxidant capacity of mature tubers exhibited regional variations. Specifically, multivariate ecological factors comprehensively influenced genetic characteristics. Temperature and moisture played pivotal roles in regulating the accumulations of proteins and phenolic glycosides, respectively. These findings underscore the significant impact of ecological factors on the shaping of G. elata, highlighting their crucial role in enhancing the quality of Chinese medicinal materials.

G protein-coupled receptors (GPCRs) are the largest family of membrane proteins in eukaryotes, with nearly 800 genes coding for these proteins. They are involved in many physiological processes, such as light perception, taste and smell, neurotransmitter, metabolism, endocrine and exocrine, cell growth and migration. Importantly, GPCRs and their ligands are the targets of approximately one third of all marketed drugs. GPCRs are traditionally known for their role in transmitting signals from the extracellular environment to the cell's interior via the plasma membrane. However, emerging evidence suggests that GPCRs are also localized on mitochondria, where they play critical roles in modulating mitochondrial functions. These mitochondrial GPCRs (mGPCRs) can influence processes such as mitochondrial respiration, apoptosis, and reactive oxygen species (ROS) production. By interacting with mitochondrial signaling pathways, mGPCRs contribute to the regulation of energy metabolism and cell survival. Their presence on mitochondria adds a new layer of complexity to the understanding of cellular signaling, highlighting the organelle's role as not just an energy powerhouse but also a crucial hub for signal transduction. This expanding understanding of mGPCR function on mitochondria opens new avenues for research, particularly in the context of diseases where mitochondrial dysfunction plays a key role. Abnormalities in the phase conductance pathway of GPCRs located on mitochondria are closely associated with the development of systemic diseases such as cardiovascular disease, diabetes, obesity and Alzheimer's disease. In this review, we examined the various types of GPCRs identified on mitochondrial membranes and analyzed the complex relationships between mGPCRs and the pathogenesis of various diseases. We aim to provide a clearer understanding of the emerging significance of mGPCRs in health and disease, and to underscore their potential as therapeutic targets in the treatment of these conditions.

Diabetic kidney disease (DKD) is one of the more common chronic kidney diseases,and its causes are complex. DKD is very easy to progress to end-stage renal disease,and the current therapeutic effect still needs to be improved. As an important excretive organ of the human body, the kidney has physiological functions such as discharging metabolic waste, regulating fluid balance, and maintaining the stability of the body's internal environment. These highly complex biochemical processes all depend on the energy support provided by mitochondria. Mitochondrial dysfunction is a key factor causing kidney injury, and the imbalance of mitochondrial homeostasis is an important link leading to mitochondrial dysfunction. The occurrence and development of DKD are often accompanied by the imbalance of mitochondrial homeostasis in renal cells. Mitochondrial autophagy, as a means of regulating mitochondrial homeostasis, is very important for the prevention and treatment of DKD. The PTEN-induced putative kinase 1 (PINK1)/Parkin pathway is one of the most classical pathways to regulate mitochondrial autophagy. Recent studies have found that some drugs can regulate the PINK1/Parkin signaling pathway to target mitochondrial homeostasis and exert renoprotective effects. In particular, traditional Chinese medicine has a significant effect on early and middle stage DKD by regulating PINK1/Parkin pathway-mediated mitochondrial autophagy. This article discussed the mechanism of PINK1/Parkin pathway in mitochondrial autophagy and DKD and reviewed the effect of PINK1/Parkin pathway-mediated mitochondrial autophagy on DKD. At the same time, it explored the therapeutic effect of traditional Chinese and western medicine on DKD mediated by PINK1/Parkin-mediated mitochondrial autophagy, aiming to broaden the ideas of traditional Chinese and western medicine for the prevention and treatment of DKD from the perspective of PINK1/Parkin regulating mitochondrial autophagy.

Redox imbalances, which result from excessive production of reactive oxygen species (ROS) or malfunctioning of the antioxidant system, are the source of oxidative stress.ROS affects all structural and functional components of cells, either directly or indirectly. In addition to causing genetic abnormalities, excessive ROS also oxidatively modifies proteins by protein oxidation and peroxidation and alters lipid structure via advanced lipoxidation, decreasing function and promoting damage or cell death. On the other hand, low levels of ROS constitute important redox-signaling molecules in various pathways that maintain cellular homeostasis and regulate key transcription factors. As a result, ROS can affect various cellular processes, such as apoptosis, migration, differentiation, and proliferation. ROS can act as signaling molecules, controlling various normal physiological activities at the cellular level. Furthermore, there is an increasing body of evidence indicating the role of ROS in various clinical conditions.In this review, we will summarize the role of ROS in physiological and pathological processes and antioxidant action during oxidative stress.
