ObjectiveThis study aims to explore the mechanism by which Yishen Huoxue Tongqiao Formula improves metabolism-neuroplasticity and treats unilateral vestibular labyrinth destruction by regulating the metabolic balance of glutamate (Glu)/γ-aminobutyric acid (GABA). Methods48 Sprague-Dawley (SD) adult rats were randomly divided into the sham operation group, model group, Yishen Huoxue Tongqiao Formula groups with low, medium, and high doses (9.20, 18.39, 36.78 g·kg-1), and betahistine group (1.62 mg·kg-1). A unilateral vestibular labyrinth destruction (vestibular dysfunction) model was established by intratympanic injection of chloroform into the right ear, while the control group received intratympanic injection of normal saline. Drugs were administered once daily for seven consecutive days. During the period, behavioral tests were performed to evaluate the behaviors of rats after unilateral vestibular labyrinth destruction. Hematoxylin-eosin (HE) staining and Nissl staining were used to observe the neuronal morphology in the medial vestibular nucleus. Golgi staining was employed to assess the number of dendritic spines of neurons in the medial vestibular nucleus. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-ESI-MS/MS) was utilized to detect Glu/GABA. Immunofluorescence and immunohistochemistry were used to detect the expressions of neuronal nuclei (NeuN), growth-associated protein 43 (GAP-43), and glial fibrillary acidic protein (GFAP). Western blot and real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) were applied to determine the expressions of glutamate-immunoreactive (Glu-IR), GABA, GFAP, postsynaptic density protein 95 (PSD-95), and GAP-43. ResultsCompared with the sham operation group, the model group presented with head deviation, balance disorder, increased tail suspension score, nuclear consolidation of medial vestibular nerve neurons, and decreased Nissl bodies (P<0.01). The number of dendritic spines in neurons and NeuN-positive cells decreased. The content of Glu decreased. The content of GABA increased (Glu/GABA decreased). The expression of GAP-43 was down-regulated, and GFAP was up-regulated (P<0.05, P<0.01). The expressions of Glu-IR, PSD-95, and GAP-43 proteins, as well as Glu-IR mRNA decreased, while the expressions of GABA and GFAP proteins and mRNA increased (P<0.05, P<0.01). Compared with those in the model group, the head deviation, imbalanced behavior, and tail suspension scores in each treatment group decreased, with alleviated neuronal injury and recovered Nissl bodies (P<0.01). The number of dendritic spines of neurons increased, and the number of NeuN-positive cells rebounded. The content of Glu increased, and the content of GABA decreased (Glu/GABA increased). GFAP was down-regulated, and GAP-43 was up-regulated (P<0.05, P<0.01). The expressions of Glu-IR, PMD-95, and GAP-43 proteins, as well as Glu-IR mRNA increased, while the expressions of GABA and GFAP proteins and mRNA decreased. The effect was more significant in the high-dose group (P<0.01). ConclusionThe Yishen Huoxue Tongqiao Formula can alleviate vestibular dysfunction, and its mechanism may be associated with regulating the metabolic balance of Glu/GABA, mitigating neural damage, improving synaptic plasticity (promoting GAP-43 expression and inhibiting GFAP expression), and facilitating vestibular compensation.

The pathogenesis of chronic wound healing is complex. It is often difficult to heal due to a long course of disease, difficulty in treatment, and it seriously affects the quality of life in patients. The active ingredients, couplet medicinals, and compound formulas of traditional Chinese medicine (TCM) possess unique advantages in the treatment of chronic wound healing. The phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway is extremely critical in the treatment of chronic wound healing by regulating a series of biological processes, including cell apoptosis, angiogenesis, and inflammatory responses. This article reviews the relevant research on the regulation of the PI3K/Akt signaling pathway by TCM to promote chronic wound healing. It has been found that the active ingredients of TCM (such as geniposide, astragaloside, and ginsenosides, etc.), and compound formulas (such as Chonghe ointment, Huanglian ointment, Shirun shaoshang ointment, etc.) mainly reduce inflammatory responses, promote angiogenesis, regulate cell autophagy, and accelerate wound healing by activating the PI3K/Akt signaling pathway; at the same time, there are also a few couplet medicinals( such as Huangqi-Honghua) and compound formulas (such as Xiangpi Shengji ointment) that exert anti-inflammatory effects by inhibiting this signaling pathway, to promote wound healing.

OBJECTIVE:
To explore the morphological characteristics of the postero-superior protuberance of the calcaneus and to explore its relationship with Haglund malformation.
METHODS:
Ankle lateral X-ray films of 391 hospitalized patients between May 2021 and June 2024 were retrospectively collected. The morphological parameters of the postero-superior protuberance of the calcaneus were measured, including the length of the base, the height of the base, and the tip angle of the postero-superior protuberance of the calcaneus, and the morphological types were classified according to the above parameters, including the peak type, the hill type, and the flat type. The related parameters of Haglund malformation were measured, including Fowler-Philipp angle (FPA), calcaneal pitch angle (CPA), parallel pitch line (PPL), Chauveaux-Liet angle (CLA), and X/Y ratio (total calcaneal length/length of greater tuberosity of calcaneus). The differences of the morphological parameters of the postero-superior protuberance of the calcaneus and the related indicators of Haglund deformity among the three types and between the males and the females were compared and analyzed, and the differences of the positive numbers of the related indicators of Haglund deformity among the three types were compared.
RESULTS:
According to the morphological parameters of the postero-superior protuberance of the calcaneus, there were 64 cases of peak type, 245 cases of hill type, and 82 cases of flat type. There was no significant difference in the length of the base of the postero-superior protuberance of the calcaneus, CPA, CLA, and X/Y ratio among the three types ( P>0.05). Among the three types, the peak type had the largest FPA and the flat type had the smallest ( P<0.05); the peak type had the smallest tip angle of the postero-superior protuberance of the calcaneus and the flat type had the largest ( P<0.05); the positive rate of PPL in the hill type was significantly higher than that in the peak type and flat type ( P<0.05); the height of the base of the postero-superior protuberance of the calcaneus in the flat type was the smallest ( P<0.05). FPA, CPA, CLA, PPL, and X/Y ratio were positive in 2, 42, 172, 142, and 77 patients, respectively. There was no significant difference in the number of positive Haglund deformity indicators among the three types ( P>0.05). There was no significant difference between male and female patients in the tip angle of the postero-superior protuberance of the calcaneus, FPA, the positive rate of PPL, and X/Y ratio ( P>0.05). The length and the height of the base of the postero-superior protuberance of the calcaneus, CPA, and CLA in male patients were significantly higher than those in female patients ( P<0.05).
CONCLUSION
The postero-superior protuberance of the calcaneus can be divided into three types: the peak type, the hill type, and the flat type. The peak type is more likely to suffer from Haglund deformity, and the males are more likely to suffer from Haglund deformity than the females.

Vasculature injury occurs rarely in traumatic brain injury but increases lifetime risk of ischemic or hemorrhage stroke. The diverse and nonspecific clinical manifestations make the diagnosis and treatment of these injuries highly challenging. With advancements in device design, endovascular treatments have become widely adopted, playing an increasingly vital role in the management of vascular diseases. The purpose of this review is to introduce and summarize endovascular treatments of traumatic cerebrovascular injury and other related pathological states after traumatic brain injury. Given the innovations of neuroendovascular devices and improvements in the techniques over the past decade, this review will outline several recent advancements in endovascular treatment strategies for cerebrovascular pathologies. Popularizing more treatment options to clinicians will benefit in dealing with a variety of clinical scenarios and reduce the overall morbidity of traumatic cerebrovascular injury.

ObjectiveTo investigate the mechanism of astragaloside-Ⅳ (AS-Ⅳ) in regulating pyroptosis to alleviate intestinal ischemia-reperfusion injury (IRI) by combining network pharmacology and in vivo experiments. MethodFirstly, the corresponding target genes of AS-Ⅳ were obtained from TraditionalChineseMedicineSystemsPharmacology(TCMSP) database and Swiss Target Prediction database, and the target genes related to intestinal IRI and Pyroptosis were obtained from GeneCards database, and the common target genes of the three were obtained by drawing Venn diagrams through unspiralized website. Protein-protein interaction (PPI) network was constructed by STRING database and Cytoscape software to screen common target genes and imported into Cytoscape software to obtain core target genes. Microbiotics platform was used for gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) enrichment analysis and prediction of the mechanism of action of AS-Ⅳ in regulating Pyroptosis to alleviate intestinal IRI. Then C57/BL6J mice were randomly divided into 5 groups normal group, model group(IR), drug administration group (IR+AS-Ⅳ), nucleotide-binding oligomerization structural domain-like receptor protein 3 (NLRP3) agonist NSS group (IR+AS-Ⅳ+NSS), and NLRP3 inhibitor MCC950 group (IR+AS-Ⅳ+MCC950) by using a randomized numerical table method. The intestinal IRI model was established by clamping the superior mesenteric artery for 45 min and resuming perfusion for 2 h in the model group, the drug administration group, the NLRP3 agonist NSS group, and the NLRP3 inhibitor MCC950 group, and the normal group was only separated from the vessels without clamping. The administration group, the NLRP3 agonist NSS group, and the NLRP3 inhibitor MCC950 group were gavaged with astragaloside dissolved in 0.1% dimethylsulfoxide (50 mg·kg-1) for 3 consecutive days before modeling, with the last gavage 2 h before modeling, and the remaining two groups were gavaged with equal amounts of saline. The NLRP3 agonist NSS group was injected intraperitoneally with 4 mg·kg-1 of NSS 1 h before modeling, and the NLRP3 inhibitor MCC950 group was injected intraperitoneally with 10 mg·kg-1 of MCC950 1 h before modeling.The mice were put to death by reperfusion for 2 h, and intestinal tissues were obtained. The levels of IL-18 and IL-1β were detected by enzyme linked immunosorbent assay(ELISA), and the protein expression of thioredoxin-binding protein (TXNIP), NLRP3, Caspase-1 and pyrocatechin D (GSDMD) were detected by Western blot, and the pathological changes of intestinal tissues were evaluated by Chiu's score. ResultNetwork pharmacological analysis showed that there were 1599 targets of intestinal IRI, 199 targets of AS-Ⅳ action, 197 targets of pyroptosis, and 20 targets common to all three. There were 10 core targets, including NLRP3, TXNIP, silencing information regulator 1 (SIRT1), high mobility group protein 1 (HMGB1), interleukin-18 (IL-18), GSDMD, and metallo matrix protease-9 (MMP-9),et al. The results of in vivo experiments showed that compared with the normal group, Chiu's score was elevated in the model group, the levels of IL-18,IL-1β inflammatory factors in mouse intestinal tissues were elevated (P<0.05), and the protein expression levels of TXNIP, NLRP3, Caspase-1, and GSDMD were elevated (P<0.05). Compared with the model group,Chiu's score was decreased in the administered group and NLRP3 inhibitor MCC950 group,the level of IL-18,IL-1β inflammatory factors in the intestinal tissue of mice was decreased(P<0.05), and the level of TXNIP,NLRP3,Caspase-1,GSDMD protein expression was decreased(P<0.05). Compared with the administered group, Chiu's score was elevated in the NLRP3 agonist NSS group, the levels of IL-18, IL-1β inflammatory factors in mouse intestinal tissues were elevated (P<0.05), and the protein expression levels of NLRP3, Caspase-1, and GSDMD were elevated (P<0.05). Compared with the NLRP3 inhibitor MCC950 group, the NLRP3 agonist NSS group had elevated Chiu's scores, elevated levels of IL-18,IL-1β inflammatory factors in mouse intestinal tissues (P<0.05), and elevated levels of TXNIP,NLRP3, Caspase-1, and GSDMD protein expression (P<0.05). ConclusionNetwork pharmacological predictions were consistent with the results of in vivo experiments, and astragaloside attenuated intestinal ischemia-reperfusion injury by inhibiting cellular pyroptosis through the TXNIP-NLRP3 signaling pathway.
