ObjectiveTo explore the therapeutic mechanism of Buchong Tiaojing prescription for rats with diminished ovarian reserve (DOR) from the perspectives of nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) inflammasome and ferroptosis. MethodsA total of 48 female SD rats were randomly divided into a normal group, a model group, low, medium, and high dose groups of Buchong Tiaojing prescription, and an MCC950 group, with eight rats in each group. Except the normal group, all the other groups were injected subcutaneously on the back of the neck with D-galactose to prepare the DOR rat model. From the 15th day of modeling, the rats in the low, medium, and high dose groups of Buchong Tiaojing prescription were subjected to gavage daily at doses of 14.4, 28.8, 57.6 g·kg-1, respectively. Rats in the MCC950 group were injected intraperitoneally with MCC950 at a dose of 10 mg·kg-1, once every other day. The interventions of all the groups lasted for 4 weeks. The estrous cycle of the rats was observed with vaginal exfoliated cell smear. Hematoxylin-eosin (HE) staining was performed to observe the development of follicles and corpus luteum in the ovary. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the levels of serum sex hormones and interleukin-1β (IL-1β). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot assay were performed to detect the mRNA and protein expression of NLRP3 inflammasome, acyl-CoA synthetase long-chain family member 4 (ACSL4), transferrin receptor 1 (TFR1), and glutathione peroxidase 4 (GPX4), and oxidative stress kits were used to detect ovarian superoxide dismutase (SOD) and malondialdehyde (MDA) levels. ResultsDuring the experiment, one rat died in the high dose group of Buchong Tiaojing prescription, and a total of 47 rats were finally included in the index tests and statistics. Compared with those in the normal group, rats in the model group had significantly disturbed estrous cycles, increased number of atretic follicles, and significant disorder of serum sex hormones. The mRNA and protein expression of NLRP3 inflammasome, ACSL4, and TFR1 in ovarian tissue was up-regulated (P<0.01), while that of GPX4 was significantly down-regulated (P<0.01). The SOD content in the ovary was decreased significantly, while the MDA level was increased (P<0.01). After drug intervention, the estrous cycle of rats was basically resumed, and the follicles at all levels were more structurally intact and significantly increased in number. Additionally, the levels of serum sex hormones and IL-1β were significantly improved. The mRNA and protein expression of NLRP3 inflammasome, ACSL4, and TFR1 were down-regulated, while that of GPX4 was significantly up-regulated, and the ovarian oxidative stress was alleviated (P<0.05, P<0.01), especially in the high dose group of Buchong Tiaojing prescription and the MCC950 group. ConclusionInflammatory injury and ferroptosis occur in the ovaries of DOR rats, and the Buchong Tiaojing prescription is able to inhibit ovarian NLRP3 inflammasome, alleviate the degree of ovarian ferroptosis, and improve ovarian reserve.

Depression is a high-incidence mental disorder with complex causes and multifaceted pathogenic mechanisms. Its pathogenesis has not yet been fully elucidated, which has hindered the development of novel and highly effective antidepressant drugs. This condition severely affects human physical and mental health while imposing a significant socio-economic burden. At present, several hypotheses exist regarding the pathogenesis of depression, including monoamine neurotransmitter imbalances, neurotrophic factor deficiencies, neural plasticity impairments, glutamate dysregulation, neuroinflammatory disorders, gut microbiota imbalances, and mitochondrial autophagy dysfunction. Currently, most clinical antidepressants are monoamine neurotransmitter reuptake inhibitors. Although they exhibit certain therapeutic effects, they are associated with significant drawbacks, such as severe adverse reactions and poor patient compliance. In contrast, traditional Chinese medicine (TCM), characterized by its multi-targeted effects, mild efficacy, and minimal side effects, has demonstrated significant advantages in the treatment of depression. Chinese medicine Polygalae Radix possesses the functions of calming the mind, enhancing cognitive functions, harmonizing the heart and kidneys, and dispelling phlegm to open orifices. It is often included in compound prescriptions for the clinical treatment of depression. Based on current hypotheses regarding the pathogenesis of depression, this paper systematically reviews research progress on the antidepressant mechanisms of Polygalae Radix from multiple perspectives, including its active components, its use in herbal pairings, and its inclusion in TCM compound prescriptions. This review aims to provide a scientific basis for the clinical application of Polygalae Radix in antidepressant therapy and to serve as a reference for the modernization of its antidepressant research.

ObjectiveTo decipher the mechanism of Wenxiao powder in alleviating corticosterone-induced depression-like behaviors in mice. MethodMale ICR mice were randomized into normal, model, paroxetine (20 mg·kg-1), and low- and high-dose (3.27, 6.54 g·kg-1, respectively) Wenxiao powder groups. The mice in normal and model groups received equal volume of saline. Other groups except the normal group were injected with corticosterone subcutaneously 0.5 h after gavage to induce depression. Mice were tested for depression-like behaviors after drug administration. Enzyme-linked immunosorbent assay (ELISA) was performed to measure the corticosterone content in the serum. Nissl staining was performed to observe the damage of hippocampal neurons. Immunofluorescence staining was employed to observe the expression of double cortin (DCX) in the dentate gyrus (DG) of the hippocampus. Western blot was employed to determine the expression of proteins in the brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB)/extracellular signal-regulated kinase (ERK)/cAMP-response element-binding protein (CREB) pathway in the hippocampus. ResultCompared with the normal group, the model group showed decreased sucrose preference rate, increased immobility time in the tail suspension test (P<0.01), and reduced residence time in the central area of the open field and the total movement distance (P<0.05, P<0.01). In addition, the modeling elevated the corticosterone level in the serum (P<0.01), decreased the volume and intensified the nuclear staining of hippocampal neurons in the DG area, reduced the expression of DCX in the DG area, and down-regulated the protein levels of BDNF, phosphorylated (p)-TrkB, p-ERK, and p-CREB in the hippocampus (P<0.05, P<0.01). Compared with the model group, low-dose Wenxiao powder improved the mouse behavivors in the sucrose preference, open field, and tail suspension tests (P<0.05, P<0.01), and high-dose Wenxiao powder improved the behaviors in the sucrose preference and open field tests (P<0.05, P<0.01). In addition, Wenxiao powder lowered the serum corticosterone level (P<0.01) and recovered the structure and morphology of neurons with obvious nuclei and presence of Nissl bodies in the DG area of the hippocampus. Moreover, Wenxiao powder at both doses promoted the expression of DCX in the DG area, and high-dose Wenxiao powder up-regulated the protein levels of BDNF, p-TrkB, p-ERK, and p-CREB in the hippocampus (P<0.05, P<0.01). ConclusionWenxiao powder can alleviate corticosterone-induced depression-like behaviors and promote neurogenesis in mice possibly by activating the BDNF/TrkB/ERK/CREB signaling pathway.

Objective:To explore the operational accuracy and operative time of oral surgery robot-assisted endodontic microsurgery on a head-simulator for clinical reference.Methods:Three pairs of surgical simulation models were set up on head-simulator. Each model included 10 positions anteriorly and posteriorly, 20 teeth for each technique, for a total of 60 teeth. An attending physician with more than 3 years clinical experience in endodontic microsurgery completed fixed-point osteotomy and apicoectomy in three groups of endodontic microsurgery under freehand (FH), static navigation (SN), and surgery robot (SR). The duration of each operation was recorded. Cone-beam CT was taken before the operation and the surgical path was planned in the software; after surgery, a plug gauge (precision gauge for measuring hole dimensions) was inserted into the surgical path for intraoral scanning. Surgical accuracy (starting point, end point, and angular deviation) was assessed in all 3 groups, and surgery time was compared.Results:The deviation at the starting point and the end point, and angular deviation was (0.37±0.11), (0.37±0.10) mm, and 0.71°±0.17°in the SR group. The deviations in the SR group were significantly lower than those in the SN group [(0.59±0.14), (0.65±0.18) mm, and 2.64°±0.75°] ( P<0.05), and both groups were significantly lower than the FH group [(1.37±0.31), (1.10±0.21) mm, and 9.84°±3.15°] ( P<0.05). The operative time in the SN group [(1.20±0.03) min] was significantly less than that in the SR group [(2.18±0.03) min] ( P<0.05), and both groups were significantly less than that in the FH group [(8.70±3.15) min] ( P<0.05). Starting point deviation, end point deviation, and angular deviation [(1.09±0.10), (0.90±0.07) mm, 7.22°±1.13°] in anterior teeth using the FH was significantly lower than the starting deviation, endpoint deviation, and angular deviation [(1.65±0.14), (1.30±0.06) mm, 12.46°±2.10°] in the posterior teeth using FH ( P<0.05), and the operative time in the anterior teeth using the FH [(5.75±0.57) min] was significantly less than that in the posterior teeth using [(11.65±1.14) min] ( P<0.05). The difference in accuracy and operative time between using SN and SR on anterior and posterior teeth was not statistically significant ( P>0.05). Conclusions:Oral surgery robot-assisted endodontic microsurgery helps improving the accuracy of clinicians′ operations and shorten the operation time.

Objective:To investigate the immune cell differentiation-induced alveolar-capillary barrier damage in septic ARDS via cell communication.Methods:Construct septic ARDS-related WGCNA network based on transcriptomic data and identify ARDS-related genes (ARGs). Constructed septic ARDS differentiation trajectories, predicted cellular communication, and screened immunodifferentiation-related genes (IDRGs) based on single-cell sequencing data. Lasso regression analysis establish immune-related RS of ARDS. ESTIMATE, CIBERSORT, and ssGSEA assessed the immune microenvironment. Metascape, GSVA and GO enrichment analyses demonstrated RS-related signaling pathways and biological processes.Results:Cell communication between immune cells and fibroblasts/endothelial cells involves 22 signaling pathways. RS containing DSTN, SNRPA, and FGL2 were differentially expressed in healthy, sepsis, and septic ARDS patients, affecting the differentiation of immune cells, endothelial cells, and fibroblasts, and regulating the infiltration of the immune cells and immune functions. The characteristic immune cells in septic ARDS included memory B cells, plasma cells, CD8 +T, and M0; DSTN was negatively correlated with M0 ( r=-0.29, P<0.05), SNRPA was positively correlated with CD8 +T ( r=0.28, P<0.05), and FGL2 was positively correlated with memory B cells ( r=0.32, P<0.05).The immune cells that were differentially expressed between RS groups, including CD4 na?ve T cells, CD4 memory-activated T cells, regulatory T cells, γ-δ T cells, M0, and activated dendritic cells. Enrichment analysis indicated the differential expression of DSTN, SNRPA, and FGL2 affected the differentiation of immune cells, the activation of immune functions, the presentation of antigens, and the depolymerization/cutting of actin filaments. Conclusions:DSTN, SNRPA, and FGL2 affect immune-related alveolar-capillary barrier damage in septic ARDS by regulating the differentiation of immune cells, fibroblasts, and endothelial cells, and are potential biomarkers for predicting the progression of septic ARDS.
