Objective:To investigate the clinicopathological features and genevariation of sporadic arteriovenous malformation (AVM) in soft tissue.Methods:Eighty cases of soft tissue sporadic AVM diagnosed in Henan Provincial People′s Hospital from January 2017 to March 2022, were retrospectively collected. The relevant indicators were detected by immunohistochemistry and fluorescent quantitative PCR, and the relevant literature was reviewed.Results:There were 42 males and 38 females patients, aged from 4 to 71 years, with a mean age of 26 years.The sites of the disease included head and neck (34 cases), limbs (24 upper limbs, 17 lower limbs) and trunk (5 cases). The main clinical manifestations were characteristic pulsation, tremor, temperature rise, local pain, ulcer or repeated bleeding, and heart failure in severe cases due to long-term hemodynamic abnormalities.Color Doppler ultrasound (CDFI) can detect the high flow characteristics of AVM.Multiple cavitary vascular shadows were seen on MRI. Microscopically, the pathological tissue involved the skin appendages, deep fat and muscle tissue, in which abnormal vascular proliferation was seen, mostly scattered, the lumen was irregularly expanded, the wall thickness was different, but most of them were thick, the vascular wall was glassy and myxoid, inflammatory cell infiltration, bleeding, thrombosis and organization were visible, and calcification was rare.Clustered proliferative muscular small vessels were found around the abnormal blood vessels.No vascular endothelial cell proliferation was found in the blood vessels of the lesion. Immunohistochemistry showed that vascular endothelial cells expressed CD31, CD34 and ERG, and muscle fibers and smooth muscle tissues in the wall expressed SMA.Elastic fiber staining showed incomplete elastic layer in the wall of the malformed artery.PIK3CA gene was detected in 15 cases, and 1 case (1/15) had mutation (mutation rate 6.7%). All cases underwent surgical resection, 73 cases were followed up for 3 months to 5 years, and 15 cases recurred.Conclusions:Sporadic AVM in soft tissue is a typical lesion of vascular malformation with high flow velocity. There are abnormal arteries and clusters of proliferating small vessels.Because of the significant difference in clinical manifestation, treatment and prognosis, pathological diagnosis should be distinguished from congenital hemangioma, intramuscular hemangioma capillary type, PTEN soft tissue hamartoma and common venous malformation.Very few cases may involve PIK3CA gene mutation, suggesting that there may be abnormal PI3K signal pathway in AVM and may participate in the occurrence and development of the disease. AVM has a high recurrence rate and needs long-term follow-up.

ObjectiveTo investigate common dyadic coping (CDC) in linking with marital satisfaction and quality of life (QOL) in patients with brain injury and their spouses in a rehabilitation facility by using common fate model (CFM). MethodsFrom October, 2022 to June, 2023, 101 brain injury inpatients and their spouses in Beijing Bo'ai Hospital completed the questionnaire of Dyadic Coping Inventory, Kansas Marital Satisfaction Scale and World Health Organization Quality of Life. ResultsThe level of CDC between patients and their spouses significantly positively correlated with their marital satisfaction for both partners (β = 0.814, P < 0.001), as well as correlated with their quality of life (β = 0.271, P = 0.038; β = 0.481, P < 0.001). For the dimensions of QOL, the physical, psychological, social relationship and environmental dimensions significantly positive correlated with the CDC for the spouses, and only psychological and social relationship dimensions for the patients. ConclusionFacing the stress of brain injury, the level of CDC within couples can positively predict their marital satisfaction and QOL, and effect seems stronger for the spouses. It is advisable to consider both brain injured patients and their spouses as a whole to promote psychological adaptation and improve rehabilitation outcomes.

Drug-induced hyperglycemia/diabetes is a global issue. Some drugs induce hyperglycemia by activating the pregnane X receptor (PXR), but the mechanism is unclear. Here, we report that PXR activation induces hyperglycemia by impairing hepatic glucose metabolism due to inhibition of the hepatocyte nuclear factor 4-alpha (HNF4α)‒glucose transporter 2 (GLUT2) pathway. The PXR agonists atorvastatin and rifampicin significantly downregulated GLUT2 and HNF4α expression, and impaired glucose uptake and utilization in HepG2 cells. Overexpression of PXR downregulated GLUT2 and HNF4α expression, while silencing PXR upregulated HNF4α and GLUT2 expression. Silencing HNF4α decreased GLUT2 expression, while overexpressing HNF4α increased GLUT2 expression and glucose uptake. Silencing PXR or overexpressing HNF4α reversed the atorvastatin-induced decrease in GLUT2 expression and glucose uptake. In human primary hepatocytes, atorvastatin downregulated GLUT2 and HNF4α mRNA expression, which could be attenuated by silencing PXR. Silencing HNF4α downregulated GLUT2 mRNA expression. These findings were reproduced with mouse primary hepatocytes. Hnf4α plasmid increased Slc2a2 promoter activity. Hnf4α silencing or pregnenolone-16α-carbonitrile (PCN) suppressed the Slc2a2 promoter activity by decreasing HNF4α recruitment to the Slc2a2 promoter. Liver-specific Hnf4α deletion and PCN impaired glucose tolerance and hepatic glucose uptake, and decreased the expression of hepatic HNF4α and GLUT2. In conclusion, PXR activation impaired hepatic glucose metabolism partly by inhibiting the HNF4α‒GLUT2 pathway. These results highlight the molecular mechanisms by which PXR activators induce hyperglycemia/diabetes.

Objective To investigate the underlying drug enhancement mechanisms of the Chuanwu (Aconiti Radix) and Huangqi (Astragali Radix) combination and toxicity reduction of Chuanwu combined with Gancao (Glycyrrhizae Radix et Rhizoma) in Wutou Decoction (乌头汤, WTD), and to elucidate the compatibility principle. Methods The active compounds and potential effective targets of the selected combinations were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Traditional Chinese Medicines Integrated Database (TCMID). The toxicity of Chuanwu (Aconiti Radix) was investigated by selecting all five toxic compounds from the literature and the TCMSP database, and obtaining their targets through SwissTargetPrediction. Targets related to rheumatoid arthritis (RA) were searched using DisGeNET, GenCards, and Online Mendelian Inheritance in Man (OMIM). Mutual targets between the drug pairs and RA were selected as potential RA therapy targets. The medicinally active compound-target network was constructed using Cytoscape 3.9.0. Gene ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed using the Database for Annotation, Visualization, and Integrated Discovery (DAVID) platform. Results We obtained 191 active compound targets for Gancao (Glycyrrhizae Radix et Rhizoma), 171 for Huangqi (Astragali Radix), and 103 for Chuanwu (Radix Aconiti) (hypoaconitine’s target was obtained through literature and SwissTargetPrediction). A total of 5872 genes were obtained for RA. A drug-active compound-target network involving 13 effect-enhancing and nine toxicity reduction targets was constructed. PGR was the main effect enhancement target, and KCNH2 was the main toxicity reduction target. The effect-enhancing targets were related to 23 GO terms (such as positive regulation of transcription from RNA polymerase II promoter, steroid hormone-mediated signaling pathway, plasma membrane, and protein binding) (P < 0.01), and 13 KEGG pathways related to synergism [such as estrogen signaling pathway, cholinergic synapse, and phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway]. The toxicity reduction targets were related to 28 GO terms (mainly involes G-protein coupled receptor signaling pathway, plasma membrane, and drug binding) (P < 0.01), and five KEGG pathways related to toxicity reduction (cholinergic synapse, calcium signaling pathway, regulation of actin cytoskeleton, neuroactive ligand-receptor interaction, and serotonergic synapse). Conclusion The combination of Chuanwu (Aconiti Radix) and Huangqi (Astragali Radix) plays an important effect-enhancing role in WTD and involves the estrogen and PI3K/Akt signaling pathways, with PGR as the core. The Chuanwu (Aconiti Radix) and Gancao (Glycyrrhizae Radix et Rhizoma) combination decreases toxicity in WTD and is associated with the cholinergic synapse and calcium signaling pathways, with KCNH2 as the core.
