The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

ObjectiveTo clarify the associations between plasma fibrinogen (Fbg) and volumetric bone mineral density (vBMD) as well as osteoporosis measured by quantitative computed tomography (QCT), and to explore the role of plasma Fbg in early screening and diagnosis of osteoporosis. MethodsPatients with hypertension who were hospitalized in the Department of Endocrinology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to June 2022 and underwent QCT examinations were included for cross-sectional analysis. The study analyzed the correlation between plasma Fbg and osteoporosis in patients. The diagnostic efficacy of plasma Fbg for osteoporosis was evaluated by the area under the receiver operating characteristic (ROC) curve (AUC). ResultsTotally 441 subjects were included in the analysis, with an average age of 46.0±14.5 years and a prevalence of osteoporosis of 6.4% (28/441). As the level of plasma fibrinogen increased, the incidence of osteoporosis significantly increased (P<0.000 1)while the average bone mineral density of L1 and L2 were significantly decreased (P<0.05). Compared with the first quartile of plasma Fbg(1.99g/L -2.37g/L), the risk of osteoporosis in the fourth quartile of plasma Fbg (3.67g/L-4.46g/L) increased by 8.85 times after adjusting for related confounding factors. ConclusionThis study found a negative correlation between plasma fibrinogen levels and bone density in patients with hypertension. Plasma fibrinogen levels may serve as a potential screening indicator for osteoporosis, aiding in early diagnosis and therapeutic monitoring. This discovery offers a new perspective for the study of bone metabolic diseases and warrants further investigation.

As a common malignant tumor of the respiratory system, the incidence and mortality of lung cancer are still rising year by year. Its pathogenesis is complex, the prognosis is poor, and it seriously affects human physical and mental health. Although existing Western medical treatments can inhibit tumor growth to a certain extent and relieve patients' painful symptoms, problems such as postoperative recurrence and metastasis, numerous adverse reactions, and the tendency to develop drug resistance make the overall therapeutic effect unsatisfactory. Therefore, it is urgent to seek more efficient and safer treatments. Adenosine monophosphate-activated protein kinase (AMPK) signaling pathway can regulate the growth, differentiation, apoptosis, and autophagy of lung cancer cells, and is extensively involved in the occurrence and development of lung cancer, thus being regarded as an important target for anti-lung cancer therapy. Traditional Chinese medicine (TCM) exerts anti-lung cancer effects through multiple pathways, mechanisms, and targets, with advantages such as preventing postoperative recurrence and metastasis, alleviating the adverse reactions of radiotherapy and chemotherapy, and improving quality of life. TCM has therefore become a key approach in current anti-lung cancer treatment. Studies have found that active components of Chinese medicine, including flavonoids, saponins, polyphenols, and terpenes, as well as Chinese medicine compound prescriptions such as Guiqi Yiyuan extract, Qingzao Jiufei decoction, and Yiqi Fuzheng formula, have significant regulatory effects on AMPK and its interacting signaling pathways. These effects include inducing autophagy and apoptosis of lung cancer cells, modulating macrophage polarization, inhibiting epithelial-mesenchymal transition, reversing drug resistance, and blocking the cell cycle, thereby exerting anti-lung cancer activity. This article reviews and summarizes recent studies on the anti-lung cancer effects of TCM, and discusses the mechanisms by which TCM regulates the AMPK signaling pathway in the treatment of lung cancer, with the aim of providing ideas and references for the development of new clinical anti-lung cancer drugs.

ObjectiveEndothelial cell dysfunction being the core link. This study explores the molecular mechanism of Danshen Tongluo formula in treating coronary artery disease-dominated panvascular disease with endothelial cell changes as the core through animal experiments and single-cell transcriptome sequencing. MethodsA rat model of coronary artery disease-dominated panvascular disease was established by ligating the left anterior coronary artery. Rats were randomized into a blank group, a model group, and a Danshen Tongluo formula (28 mg·kg-1·d-1) group. The efficacy was evaluated by examining the cardiac ultrasound, determination of the plasma level of N-terminal pro-brain natriuretic peptide, and pathological staining. After single-cell sequencing, SingleR package, public datasets, and related literature were used for annotation of the cells. Cell chat was used for intercellular communication and ligand-receptor analysis, and scmetabolism was used for metabolic analysis of endothelial cells. ResultsAnimal experiments showed that Danshen Tongluo formula reduced the N-terminal pro-brain natriuretic peptide ( NT-proBNP ) level (P<0.05), ameliorated myocardial cell damage and fibrosis, and increase left ventricular ejection fractions (LVEF) in the rat model of heart failure after myocardial infarction(P<0.05). Single-cell sequencing results showed that Danshen Tongluo formula increased the proportion of arterial endothelial cells, venous endothelial cells, and capillary-arterial endothelial cells, while reducing the proportion of capillary-venous endothelial cells. In addition, this formula increased the interaction intensity of endothelial cells with cardiomyocytes and M1 macrophages and reduced the interaction intensity of endothelial cells with fibroblasts and T cells. Danshen Tongluo formula upregulated CXCL12-CXCR4 signaling in endothelium-B cells and Ptprm-Ptprm signaling in endothelial endothelial cells, while downregulating Mif-(CD74+CXCR44) signaling in endothelium-M1 macrophages and Mif-(CD74+CD44) signaling in endothelium-M2 macrophages. It reduced the citric acid cycle, oxidative phosphorylation, and glycolysis and increased the glycolysis/oxidative phosphorylation ratio in endothelial cells. GO and KEGG enrichment analysis showed that arterial endothelial cells, venous endothelial cells, and venous capillary endothelial cells can all regulate oxidative phosphorylation, cell adhesion molecules, and tyrosine metabolism. Lymphatic endothelial cells regulate immunity and vascular constriction to participate in the metabolism of various amino acids and fatty acids. ConclusionDanshen Tongluo Formula can ameliorate coronary artery disease-dominated panvascular disease by changing the composition of endothelial cells and regulating the communication between myocardial endothelial cells and non-endothelial cells.

Gastrointestinal tumors (GTs), including colorectal cancer, gastric cancer, liver cancer, pancreatic cancer, and esophageal cancer, are increasing in incidence worldwide and have become one of the major diseases threatening human health. Tumor stem cells (TSCs), an undifferentiated subpopulation within tumor tissues, possess biological characteristics such as self-renewal, multidirectional differentiation, high tumorigenicity, and resistance to radiochemotherapy. They play an important role in the occurrence, progression, recurrence, and metastasis of GTs and have increasingly become a research hotspot in GT treatment. Although modern medicine has made remarkable progress, there remain many problems in therapeutic approaches targeting TSCs. In this context, traditional Chinese medicine (TCM), with its favorable safety profile and multi-target mechanisms, has shown potential advantages and value in regulating TSCs. It can reduce TSC drug resistance, enhance the sensitivity of tumor cells to chemotherapeutic agents, inhibit tumor growth and metastasis, and has shown unique advantages in improving the quality of life and prolonging the survival of GT patients. Studies have found that active components of Chinese medicine, such as terpenoids, polyphenols, flavonoids, glycosides, and quinones, and Chinese medicine compound formulas, including Zuojin pills, Sijunzi decoction, Biejiajian pills, and Xuanfu Daizhe decoction, can inhibit TSCs-related signaling pathways such as the Notch signaling pathway, the Wnt/β-catenin signaling pathway, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway, and the Hippo signaling pathway. They also reduce the expression of TSC surface markers, including sex-determining region Y-box 2 (SOX2), sex-determining region Y-box 9 (SOX9), octamer-binding transcription factor 4 (OCT4), prominin-1 (CD133), cluster of differentiation 44 (CD44), cluster of differentiation 24 (CD24), and thyroid transmembrane protein 1 (CD90), thereby hindering TSC differentiation, accelerating their metabolic processes, improving the tumor microenvironment, and consequently inhibiting GT growth. This study collects and analyzes recent research on the regulation of TSCs by TCM in the treatment of GT, aiming to provide a new theoretical basis for tumor therapy with TCM, expand its application in the comprehensive treatment of GT, and offer new therapeutic ideas and methods for clinical practice.
