ObjectiveTo explore the mechanism of Shouhui Tongbian capsules in treating constipation based on the research foundation of its active components combined with network pharmacology and animal experiments. MethodsThe drug components were imported into SwissTargetPrediction to predict the targets of Shouhui Tongbian capsules， and constipation-related targets were collected from disease databases. A protein-protein interaction （PPI） network was constructed for the common targets shared by Shouhui Tongbian capsules and constipation to screen key targets， which was followed by gene ontology （GO） function and Kyoto encyclopedia of genes and genomes （KEGG） pathway enrichment analyses. A "bioactive component-target-pathway" network was constructed， and the core components of Shouhui Tongbian capsules in treating constipation were screened based on the topological parameters of this network. Molecular docking was employed to predict the binding affinity of core components to key targets. A mouse model of constipation was constructed to screen the key pathways and targets of the drug intervention in constipation. ResultsThe PPI network revealed six key constipation-related targets： protein kinase B （Akt1）， B-cell lymphoma-2 （Bcl-2）， glycogen synthase kinase-3β （GSK-3β）， cyclooxygenase-2 （PTGS2）， estrogen receptor 1 （ESR1）， and epidermal growth factor receptor （EGFR）. The KEGG pathway analysis showed that the phosphatidylinositol 3-kinase （PI3K）/Akt signaling pathway was the most enriched. The topological parameter analysis of the "bioactive component-target-pathway" network screened out the top 10 core components： auranetin， isosinensetin， naringin， diosmetin， quercetin， apigenin， luteolin， hesperidin， isorhapontigenin， and chrysophanol. Molecular docking results showed that the 10 core components had strong binding affinity with the 6 key targets. Animal experiments showed that after intervention with different doses of Shouhui Tongbian capsules， the time to the first black stool excretion was reduced and the fecal water content and small intestine charcoal propulsion rate of mice were improved. After treatment with Shouhui Tongbian capsules， the colonic mucosal injury and glandular arrangement were alleviated， and the muscle layer thickness was increased. Western blot results showed that Shouhui Tongbian capsules recovered the expression of apoptosis-related molecules mediated by the PI3K/Akt pathway in the colonic tissue of constipated mice. Terminal-deoxynucleotidyl transferase-mediated nick end labeling （TUNEL） results showed that the cell apoptosis rate of the colon significantly reduced after intervention with Shouhui Tongbian capsules. ConclusionThe results of network pharmacology and animal experiments confirmed that Shouhui Tongbian capsules can treat constipation through multiple targets and pathways. The capsules can effectively intervene in loperamide-induced constipation in mice by regulating the constipation indicators and reducing cell apoptosis in the colon tissue via activating the PI3K/Akt signaling pathway.

Postoperative pathological results showed minimal residual tumor cells, indicating that ⁹⁰Y-SIRT has good efficacy and safety in downstaging and conversion of HCC, thereby facilitating subsequent surgical resection.

Chronic constipation （CC） is one of the common and frequent functional gastrointestinal diseases in clinic. At present， the overall therapeutic effect of CC is still not satisfactory in China and abroad， which seriously affects the quality of life of patients. The pathophysiological mechanism of constipation has not been fully elucidated， and studies have mainly focused on the dysfunction of the enteric nervous system （ENS）， abnormalities of Cajal interstitial cells （ICCs）， alterations in mucosal immune function （low-grade intestinal inflammation， intestinal barrier damage， and immune activation）， abnormalities of gastrointestinal hormones， dysregulation of intestinal flora， and dysfunctions of intestinal dynamics. Traditional Chinese medicine （TCM） is a unique and precious resource in China with good efficacy and safety. TCM and its active ingredients can effectively treat constipation， and its mechanism of action needs to be further investigated. Signaling pathways are involved in the development of constipation， which is one of the main targets in the study of pathological mechanisms of constipation and the pharmacological study of therapeutic drugs. Therefore， the authors searched PubMed， China National Knowledge Infrastructure （CNKI）， and other literature databases with the keywords of ''constipation''， ''signaling pathway''， and ''traditional Chinese medicine'' to systematically summarize the signaling pathways related to constipation regulated by TCM. The comprehensive analysis shows that TCM mainly plays a role in regulating autophagy， apoptosis， and proliferation and ensuring anti-oxidative stress， anti-inflammation， and protection of intestinal barrier of ICCs by modulating signaling pathways such as stem cell factor/tyrosine kinase receptor （SCF/c-kit）， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， 5-hydroxytryptophan （5-HT）， mitogen-activated protein kinases （MAPK）， and Toll-like receptors （TLRs）. TCM regulates neurotransmitter secretion and intestinal water metabolism to improve constipation. This demonstrates the advantages of multi-level， multi-target， and multi-level effects of TCM， and in-depth research can provide new ideas for exploring the pathogenesis of constipation and developing new drugs.

The synthesis and regulatory mechanism of tanshinones, the key active constituents of Salvia miltiorrhiza, have been a hot topic of research. The paper summarized the research findings on the regulation of tanshinone biosynthesis by transcription factors such as AP2/ERF, bHLH, MYB, bZIP, and WRKY in recent years. The review identifies the existing issues in the transcriptional regulation studies of Salvia miltiorrhiza and discusses the research direction of transcription factors in the regulation of tanshinone biosynthesis, providing a theoretical basis for the further discovery and utilization of functional genes involved in the regulation of tanshinone bioactive constituents.

Based on the long bud stage phenotype of a new Lonicera japonica Flos variety "Huajin 6", using "Huajin 6" and "Da Mao Hua" as materials, probing the mechanism of its phenotype formation. Detection of endogenous Jasmonic acid hormones (JAs) content; the genes related to jasmonic acid (JA) synthesis were identified by transcriptome analysis of Lonicera japonica; flower buds and flowers of "Huajin 6" and "Da Mao Hua" were collected at different periods, and the qRT-PCR (quantitative real-time PCR) technique was used to analyze the trend of the expression of synthesis-related enzyme genes in Lonicera japonica Flos during the bud stage. The study found that the content of JAs in "Huajin 6" Lonicera japonica Flos was significantly lower than that in "Da Mao Hua"; applying exogenous methyl-jasmonate (MeJA) to "Huajin 6" can restore its flowering phenotype, making it close to wild type Lonicera japonica Flos; there are significant differences in the expression of two allene oxide synthase genes (AOS), three lipoxygenase genes (LOX), and two allene oxide cyclase genes (AOC) in the flowers and buds of "Huajin 6" and "Da Mao Hua" at different periods. It is hypothesized that the low expression of JA synthesis-related enzyme genes in " Huajin 6" leads to the blockage of JA synthesis, which causes the formation of the long bud phenotype. This study laid a certain foundation for the genetic breeding of Lonicera japonica, provided a new idea for the improvement of Lonicera japonica varieties, and provided a reference for the study of JAs in plant flower organs.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Chronic constipation （CC） is one of the most common functional gastrointestinal diseases. At present， the overall therapeutic effect of CC is still not satisfactory worldwide， which seriously affects the quality of life and social function of patients. The etiology and pathophysiological mechanism of constipation are still unclear. It involves comprehensive factors such as heredity， social psychology， diet， intestinal flora imbalance， intestinal motility disorder， visceral sensitivity change， pelvic floor muscle group dysfunction and enteric nervous system （ENS） disorder. Among them， the abnormal factors of the brain-gut-microbiome axis are particularly significant. The brain-gut-microbiome axis is a complex network of interactions between the intestine and the brain， integrating and coordinating the physiological functions and pathological processes of the gastrointestinal tract. Microorganisms in the intestinal lumen play an important role in it， and can communicate with the intestinal tract and the central nervous system through nerve， endocrine and immune pathways. As a key brain-gut peptide in the regulation pathway of the brain-gut-microbiome axis， 5-hydroxytryptamine （5-HT） is involved in the regulation of gastrointestinal motility， sensation and secretion. The abnormal conduction of the 5-HT signaling pathway is closely related to the occurrence and development of constipation. Traditional Chinese medicine（TCM） is a unique precious resource in China， which has good curative effects and safety. In recent years， it has received extensive attention in the treatment of constipation. TCM and active ingredients， acupuncture and massage specifically regulate 5-HT signal transmission， so that the expressions of related molecules tend to be suitable for individual disease state levels to effectively improve constipation symptoms， with unique advantages. Therefore， this study used ''constipation''， ''intestinal flora''， ''5-HT''， and ''traditional Chinese medicine'' as the keywords to search PubMed， China National Knowledge Infrastructure （CNKI） and other literature databases. The correlation between 5-HT and constipation as well as brain-gut-microbiome axis and the research progress of TCM intervention in the 5-HT signaling pathway in the treatment of constipation were reviewed in order to explore the potential therapeutic value of 5-HT system in this disease and provide references for subsequent research.
