Objective To explore the effective induction scheme for differentiation of adipose-derived mesenchymal stem cell (ADMSC) to insulin producing cell (IPC). Methods Different schemes of small molecule compound were used to induce the differentiation of ADMSC. The purity of cells was analyzed by flow cytometry and the morphological changes of cells were observed under the microscope. The quality, performance and insulin related indicators of cells were detected by hematoxylin-eosin and immunohistochemical staining. The maturity and activity of cells were detected by dithizone (DTZ) and diacetylfluorescein/propidium iodide staining. The induction effect of ADMSC differentiated into IPC was analyzed. Results The purity of ADMSC reached more than 99%, and the sphere forming properties of schemes Ⅰ, Ⅱ and Ⅲ were good. Cell induction mass, the expression effects of pancreatic and duodenal homeobox 1 (PDX1), musculoaponeurotic fibrosarcoma oncogene homolog A (MAFA) and insulin and C peptide of schemes Ⅰ were both better than those of other schemes. The DTZ staining depth may be related to IPC maturity, among which the number of apoptotic cells in scheme Ⅰ was significantly less than that of scheme Ⅱ and Ⅲ. Conclusions Induction scheme Ⅰ may improve the differentiation efficiency of ADMSC to IPC and lay a certain foundation for future clinical IPC transplantation applications.

Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.

This study, anchored in the traditional Chinese medicine (TCM) syndrome differentiation and treatment principles alongside the clinical characteristics of sepsis in Western medicine, extensively gathers and meticulously dissects the latest research findings on sepsis animal models from both Chinese and international sources. Adhering strictly to TCM syndrome diagnostic criteria for sepsis, the study conducts a thorough evaluation of various animal models across multiple dimensions, including clinical manifestations, pathological changes, and biomarker expressions, so as to reflect the degree of resemblance these models have to human sepsis TCM syndromes. The results reveal that the colon stent implantation model exhibits a higher degree of congruence with both TCM and Western medicine standards, particularly aligning with the diagnosis of the "Fu-Qi obstruction syndrome". Conversely, the extraperitoneal sepsis model shows a higher degree of congruence with TCM, fitting more closely with the diagnosis of "acute deficiency syndrome" and emphasizing the core pathogenesis of Qi deficiency in sepsis. These findings not only augment the diversity of sepsis animal models but also highlight the necessity and potential of integrated TCM and western medicine research. Current sepsis animal models predominantly focus on western pathophysiological mechanisms, with limited direct incorporation of TCM syndrome differentiation elements. This underscores the need, in future study designs, to actively explore integrating TCM syndrome classification and intervention principles into model development. This could be achieved by manipulating model-inducing factors and observing more TCM-specific symptoms and signs among other strategies, so as to establish sepsis models that more closely resemble clinical reality and incorporate both TCM and western medical perspectives.

Autophagy is the main degradation and recycling pathway for abnormal aggregates and damaged organelles in cells,and it maintains the normal metabolic balance and material renewal in cells.Autophagy has neuroprotective effects and can affect the functional state of the nervous system by regulating homeostasis,development,apoptosis,and other physiological processes of neurons and glial cells.In recent years,a large number of studies have shown that nervous system diseases are closely related to abnormal autophagy,and inhibition or overactivation of autophagy affects the occurrence and development of depression,neurodegenerative diseases,and schizophrenia.Understanding the mechanisms of autophagy in nervous system diseases is of great significance for their prevention and treatment.This paper mainly reviews the current progress of autophagy research and the above diseases of the nervous system,providing a reference for further research into these diseases.

Objective To compare the effects of ginsenosides Rg1 and Rb1 on depression-and anxiety-like behaviors in chronic unpredictable stress-induced rats.Methods Seventy male SPF grade SD rats were tested for sugar and water preference after 5 days of adaptation and divided into seven groups according to their preference index:a control group,model group,fluoxetine hydrochloride group,ginsenoside Rg1 24 mg/kg group,ginsenoside Rg1 48 mg/kg group,ginsenoside Rb1 33 mg/kg group,and ginsenoside Rb1 67 mg/kg group.All rats,except for the control group,were subjected randomly to one or two different stimulating factors every day for a total of 35 days.On the 36th day,behavioral experiments including sugar and water preference,open field,novel environment feeding inhibition,elevated cross maze,and forced swimming experiments were conducted to investigate the anti-depression and anti-anxiety effects of the treatments.Serum and hippocampal levels of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-α and serum corticosterone were measured by enzyme-linked immunosorbent assay.Results Compared with the model group,ginsenoside Rg1 and Rb1 significantly increased sucrose consumption in the sucrose preference test and decreased immobility in the forced swimming test.Ginsenoside Rg1(48 mg/kg)significantly reduced the latency to eat in the novelty-suppressed feeding test,and ginsenoside Rg1(24 and 48 mg/kg)significantly increased the percentage of open arm entries and time in the elevated cross maze test.Serum corticosterone levels were significantly decreased in the ginsenoside Rg1 and Rb1 groups,serum IL-1β and IL-6 levels were significantly decreased in the ginsenoside Rg1(48 mg/kg)group,serum TNF-α and IL-6 levels were significantly decreased in the ginsenoside Rb1(33 mg/kg)group,and IL-1β,IL-6,and TNF-α levels in the hippocampus were significantly decreased in the ginsenoside Rg1(48 mg/kg)and Rb1(67 mg/kg)groups.Conclusions Both ginsenosides can regulate the hypothalamic-pituitary-adrenal axis and inhibit neuroinflammation,improving depression-and anxiety-like behaviors in rats induced by chronic unpredictable stress.Ginsenoside Rg1 has a significantly better anti-anxiety effect than Rb1.
