Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective To investigate the clinical relevance and diagnostic or prognostic value of ST3β-galactoside α-2, 3-sialyltransferase 1 (ST3GAL1) in glioma and to confirm its role in promoting malignant phenotypes. Methods Using data from The Cancer Genome Atlas (TCGA) database, we analyzed the correlation between ST3GAL1 expression levels in glioma and clinical parameters to evaluate its diagnostic and prognostic value. The impact of ST3GAL1 on malignant phenotypes of glioma cells-including proliferation, cell cycle progression, apoptosis, and invasion was further validated through ST3GAL1 knockdown experiments. Results The expression level of ST3GAL1 was significantly higher in glioma tissues compared to healthy brain tissues and showed a strong correlation with clinical characteristics of glioma patients. Survival analysis and receiver operating characteristic (ROC) curve demonstrated that ST3GAL1 could serve as a potential diagnostic and prognostic biomarker for glioma. Knockdown of ST3GAL1 suppressed proliferation, invasion, and migration capabilities of glioma cell lines, and induced G1-phase cell cycle arrest. Conclusion ST3GAL1 promotes malignant phenotypes in glioma and plays a critical role in its malignant progression, suggesting its potential as a biomarker for glioma diagnosis and prognosis.

OBJECTIVES: To develop a heterogeneous graph prediction method based on the fusion of multi-layer semantics and topological information for addressing the challenges in drug-target interaction prediction, including insufficient modeling of high-order semantic dependencies, lack of adaptive fusion of semantic paths, and over-smoothing of node features. METHODS: A heterogeneous graph network with multiple types of entities such as drugs, proteins, side effects, and diseases was constructed, and graph embedding techniques were used to obtain low-dimensional feature representations. An adaptive metapath search module was introduced to automatically discover semantic path combinations for guiding the propagation of high-order semantic information. A semantic aggregation mechanism integrating multi-head attention was designed to automatically learn the importance of each semantic path based on contextual information and achieve differentiated aggregation and dynamic fusion among paths. A structure-aware gated graph convolutional module was then incorporated to regulate the feature propagation intensity for suppressing redundant information and redcuing over-smoothing. Finally, the potential interactions between drugs and targets were predicted through an inner product operation. RESULTS: Compared with existing drug-target interaction prediction methods, the proposed method achieved an average improvement of 3.4% and 2.4%, 3.0% and 3.8% in terms of the area under the receiver operating characteristic curve (AUC) and the area under the precision-recall curve (AUPRC) on public datasets, respectively. CONCLUSIONS The drug-target interaction prediction method developed in this study can effectively extract complex high-order semantic and topological information from heterogeneous biological networks, thereby improving the accuracy and stability of drug-target interaction prediction. This method provides technical support and theoretical foundation for precise drug target discovery and targeted treatment of complex diseases.

Zebrafish larvae are useful for identifying chemicals against lateral line (LL) hair cell (HC) damage and this type of chemical screen mainly focuses on searching for protectors against cell death. To expand the candidate pool of HC protectors, a self-built acoustic escape response (AER)-detecting system was developed to apply both low-frequency near-field sound transmission and AER image acquisition/processing modules. The device quickly confirmed the changed LL HC functions caused by most known ototoxins, protectors, and neural transmission modifiers, or knockdown of LL HC-expressing genes. With ten devices wired in tandem, five 'hit' chemicals were identified from 124 cyclin-dependent kinase inhibitors to partially restore cisplatin-damaged AER in less than a day. AS2863619, ribociclib, and SU9516 among the hits, protected the HCs in the mouse cochlea. Therefore, using free-swimming larval zebrafish, the self-made AER-detecting device can efficiently identify compounds that are protective against HC damage, including cell death and loss-of-function.

Microglial functions are linked to Ca²⁺ signaling, with endoplasmic reticulum (ER) calcium stores playing a crucial role. Microglial abnormality is a hallmark of Alzheimer's disease (AD), but how ER Ca²⁺ receptors regulate microglial functions under physiological and AD conditions remains unclear. We found reduced ryanodine receptor 2 (Ryr2) expression in microglia from an AD mouse model. Modulation of RyR2 using S107, a RyR-Calstabin stabilizer, blunted spontaneous Ca²⁺ transients in controls and normalized Ca²⁺ transients in AD mice. S107 enhanced ATP-induced migration and phagocytosis while reducing ramification in control microglia; however, these effects were absent in AD microglia. Our findings indicate that RyR2 stabilization promotes an activation state shift in control microglia, a mechanism impaired in AD. These results highlight the role of ER Ca²⁺ receptors in both homeostatic and AD microglia, providing insights into microglial Ca²⁺ malfunctions in AD.

Objective To investigate whether adjuvant therapy can bring survival benefits to patients with esophageal squamous cell carcinoma (ESCC) who have received neoadjuvant therapy plus esophagectomy. Methods Studies were identified by searching databases including PubMed, EMbase, Web of Science, The Cochrane Library and CNKI from inception to November 2022 to collect studies which conformed to the objective of this study. Clinical outcomes including overall survival (OS) and recurrence-free survival (RFS) were extracted from eligible studies after screening. RevMan 5.4 and Stata 14.0 were used to perform the meta-analysis. Results A total of 9 studies were selected including 1 340 patients. Compared with the neoadjuvant therapy plus surgery (NS) group, the neoadjuvant therapy plus surgery+adjuvant therapy (NS+A) group had no significant benefit in the OS [HR=0.88, 95%CI (0.75, 1.02), P=0.09], but had remarkable benefit in the RFS [HR=0.75, 95%CI (0.58, 0.97), P=0.03]. Subgroup analysis by nodal status showed that adjuvant therapy could improve the RFS of patients with node-positive disease. Prolonged OS was observed in the patients with both positive and negative nodes but not in the patients with only positive nodes. In terms of the subgroup analysis by prescription, it revealed that triple agents exhibited advantages in improving RFS but not OS. However, dual agents did not bring additional survival benefits to the NS+A group compared with the NS group. Subgroup analysis by adjuvant therapy indicated that neither postoperative chemoradiotherapy nor chemotherapy improved OS, whereas postoperative chemoradiation elongated RFS. Conclusion Adjuvant therapy can improve the prognosis of patients with ESCC after neoadjuvant therapy followed by esophagectomy.

Objective: To analyze the effectiveness of body image education curriculum on grade 4-6 students of early adolescence in primary schools, so as to provide teaching pructice research eridence for promoting positive body image during adolescence. Methods: A primary school in Chengdu was selected as an experimental school, who offered 6 projects, each project 1 class hour, each chass hour 40 minutes, an average of 1.5 weeks body image education curriculum (body changes during adolescent, values, physical appearance, gender diverity expression and aesthetic diversity). The other school had the same school district conditions, school size and nature, teachers and teaching environment, and had no body image education courses. A pre-test and post-test survey was conducted in April and May 2023 on students in grades 4 to 6 in both schools through the Body Image State Scale adopting cluster sampling. Results: The pre-test scores of body image in experimental school and control school were (34.99±8.72) and (35.74±8.57) respectively, with no significantly statistical difference ( t=-1.29, P >0.05). The post-test scores of body image in experimental school and control school were (37.09±10.40) and (35.70±8.78) respectivily. There was a significant difference in body image between pre-test and post-test scores in experimental school ( t=-5.70, P <0.01), while no significant difference in control school ( t=0.13, P >0.05). There were significant differences in body image between pre-test and post-test scores among students of different BMI groups in experimental and control schools ( F =16.01, 7.19, 9.64, 5.30, P <0.01). Conclusions Body image education curriculum in early adolescence is beneficial for improving students body satisfaction. To help students develop a positive body image in early adolescence, it is necessary to implement relevant curriculum education in schools as early as possible.
