Triggering receptor expressed on myeloid cells 2 (TREM2)-mediated microglial phagocytosis is an energy-intensive process that plays a crucial role in amyloid beta (Aβ) clearance in Alzheimer's disease (AD). Energy metabolic reprogramming (EMR) in microglia induced by TREM2 presents therapeutic targets for cognitive impairment in AD. Jiawei Xionggui Decoction (JWXG) has demonstrated effectiveness in enhancing energy supply, protecting microglia, and mitigating cognitive impairment in APP/PS1 mice. However, the mechanism by which JWXG enhances Aβ phagocytosis through TREM2-mediated EMR in microglia remains unclear. This study investigates how JWXG facilitates microglial phagocytosis and alleviates cognitive deficits in AD through TREM2-mediated EMR. Microglial phagocytosis was evaluated through immunofluorescence staining in vitro and in vivo. The EMR level of microglia was assessed using high-performance liquid chromatography (HPLC) and enzyme-linked immunosorbent assay (ELISA) kits. The TREM2/protein kinase B (Akt)/mammalian target of rapamycin (mTOR)/hypoxia-inducible factor-1α (HIF-1α) signaling pathway was analyzed using Western blotting in BV₂ cells. TREM2^-/- BV₂ cells were utilized for reverse validation experiments. The Aβ burden, neuropathological features, and cognitive ability in APP/PS1 mice were evaluated using ELISA kits, immunohistochemistry (IHC), and the Morris water maze (MWM) test. JWXG enhanced both the phagocytosis of EMR disorder-BV₂ cells (EMRD-BV₂) and increased EMR levels. Notably, these effects were significantly reversed in TREM2^-/- BV₂ cells. JWXG elevated TREM2 expression, adenosine triphosphate (ATP) levels, and microglial phagocytosis in APP/PS1 mice. Additionally, JWXG reduced Aβ-burden, neuropathological lesions, and cognitive deficits in APP/PS1 mice. In conclusion, JWXG promoted TREM2-induced EMR and enhanced microglial phagocytosis, thereby reducing Aβ deposition, improving neuropathological lesions, and alleviating cognitive deficits.

An 82-year-old female patient with atrial fibrillation and heart failure was treated with dabigatran etexilate 110 mg twice daily for 6 years. Two months ago, the patient′s lower limb edema was aggravated and urine output was reduced. Considering the worsening of the patient′s heart failure, torasemide tablets and spironolactone tablets were given, but her symptoms were not improved. Two days ago, the patient had scattered petechiae on the whole skin, tarry stools, and reduced urine (200 ml daily). Laboratory tests showed hemoglobin (Hb) 63 g/l, prothrombin time (PT) 39.5 s, activated partial thromboplastin time (APTT) 117.2 s, thrombin time (TT) >300 s, and international normalized ratio (INR) 3.64; the fibrinogen (Fib) could not be measured. Coagulation dysfunction and gastrointestinal bleeding caused by dabigatran etexilate were considered. Dabigatran etexilate was discontinued, and intravenous infusion of idarucizumab injection (2.5 g) was given twice. Then gastrointestinal bleeding in the patient disappeared and laboratory tests showed PT 12.7 s, APTT 42.4 s, TT 18.8 s, INR 1.18, and Fib 2.67 g/L. After 8 days, the patient′s cardiac function was improved, the skin ecchymosis subsided, and laboratory tests showed Hb 84 g/L, PT 14 s, APTT 37.8 s, TT 41.2 s, INR 1.3, Fib 2.26 g/L, and negative fecal occult blood test.

Gastrointestinal motility disorder is an important cause of digestive system diseases. Patients often suffer from nausea， vomiting， gastric retention， gastroparesis， constipation， and many other symptoms， and their quality of life is seriously reduced. Prokinetic agents are routinely used in clinical practice， but their long-term use is prone to problems such as reduced efficacy and increased adverse reactions. Since the incidence of gastrointestinal diseases has continued to rise globally in recent years， there is an urgent need for clinical development of safe and effective treatment strategies. Aurantii Fructus， a traditional Chinese medicine， has the effect of smoothing Qi and eliminating distention， and it has been used to treat gastrointestinal diseases for thousands of years. In modern clinical practice， it is mainly used for the treatment and auxiliary treatment of various gastrointestinal diseases such as functional dyspepsia， functional constipation， and irritable bowel syndrome. The efficacy is remarkable， and no adverse reactions have been reported at conventional doses. Therefore， it can greatly improve the symptoms of patients with gastrointestinal diseases and improve their quality of life. Modern research has revealed that there are many active components in Aurantii Fructus， among which flavonoids have the highest content and the most types. Flavonoids are the main active components in Aurantii Fructus to regulate gastrointestinal motility. Aurantii Fructus and its active components can affect gastrointestinal hormones， neural pathways， Cajal mesenchymal cells， and other multiple mechanisms. They can adjust gastrointestinal motility and correct gastrointestinal motility disorders， showing potential application value in the treatment of gastrointestinal motility disorders. However， a comprehensive analysis of Aurantii Fructus in this aspect is still lacking. This study summarized the pharmacological activities of active components of Aurantii Fructus extract and its flavonoids， volatile oils， alkaloids， and coumarin on the regulation of gastrointestinal motility and explored the latest research progress on its mechanism. Finally， the adverse reactions of Aurantii Fructus were summarized. It aims to provide a scientific basis for the research and clinical application of Aurantii Fructus and its active components in the regulation of gastrointestinal motility.

Glioblastoma multiforme (GBM), a highly malignant and heterogeneous brain tumor, contains various types of tumor and non-tumor cells. Whether GBM cells can trans-differentiate into non-neural cell types, including mural cells or endothelial cells (ECs), to support tumor growth and invasion remains controversial. Here we generated two genetic GBM models de novo in immunocompetent mouse brains, mimicking essential pathological and molecular features of human GBMs. Lineage-tracing and transplantation studies demonstrated that, although blood vessels in GBM brains underwent drastic remodeling, evidence of trans-differentiation of GBM cells into vascular cells was barely detected. Intriguingly, GBM cells could promiscuously express markers for mural cells during gliomagenesis. Furthermore, single-cell RNA sequencing showed that patterns of copy number variations (CNVs) of mural cells and ECs were distinct from those of GBM cells, indicating discrete origins of GBM cells and vascular components. Importantly, single-cell CNV analysis of human GBM specimens also suggested that GBM cells and vascular cells are likely separate lineages. Rather than expansion owing to trans-differentiation, vascular cell expanded by proliferation during tumorigenesis. Therefore, cross-lineage trans-differentiation of GBM cells is very unlikely to occur during gliomagenesis. Our findings advance understanding of cell lineage dynamics during gliomagenesis, and have implications for targeted treatment of GBMs.

Long non-coding RNAs (lncRNAs) regulate transcription to control development and homeostasis in a variety of tissues and organs. However, their roles in the development of the cerebral cortex have not been well elucidated. Here, a bioinformatics pipeline was applied to delineate the dynamic expression and potential cis-regulating effects of mouse lncRNAs using transcriptome data from 8 embryonic time points and sub-regions of the developing cerebral cortex. We further characterized a sense lncRNA, SenZfp536, which is transcribed downstream of and partially overlaps with the protein-coding gene Zfp536. Both SenZfp536 and Zfp536 were predominantly expressed in the proliferative zone of the developing cortex. Zfp536 was cis-regulated by SenZfp536, which facilitates looping between the promoter of Zfp536 and the genomic region that transcribes SenZfp536. Surprisingly, knocking down or activating the expression of SenZfp536 increased or compromised the proliferation of cortical neural progenitor cells (NPCs), respectively. Finally, overexpressing Zfp536 in cortical NPCs reversed the enhanced proliferation of cortical NPCs caused by SenZfp536 knockdown. The study deepens our understanding of how lncRNAs regulate the propagation of cortical NPCs through cis-regulatory mechanisms.

Objective:To investigate the regulatory effects of endogenous nitric oxide (NO) on the activity of superoxide dismutase-1 (SOD1) and apoptosis of human umbilical vein endothelial cells (HUVECs).Methods:HUVECs were taken as the research object.The endothelial NO synthase (eNOS) short hairpin RNA(shRNA) lentivirus was employed to transfect HUVECs to knock down eNOS.HUVECs were divided in 4 groups: the scramble group, the eNOS shRNA group, the eNOS shRNA + sodium nitroprusside(SNP) group and the eNOS shRNA+ SNP+ tris (2-carboxyethyl) phosphine hydrochloride (TCEP) group.The protein expressions of eNOS and SOD1 dimer/monomer in cells were detected by western blot.The activity of SOD was detected by the enzyme-linked immunosorbent assay.The NO content in cells was detected with NO fluorescence probe.The level of superoxide anion in HUVECs was detected with dihydropyridine (DHE). The terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) assay was adopted to detect the apoptosis of HUVECs in situ.Results:Compared with the scramble group, the endogenous NO content (2.690±0.420 vs.15.029±2.193, P<0.01), eNOS protein expression (1.000±0.778 vs.3.141±0.199, P<0.01), SOD1 dimer/monomer ratio (4.6±1.0 vs.7.6±2.0, P<0.05) and SOD activity [(0.432±0.254) Carmen′s unit/10 4 cell vs.(1.000±0.116) Carmen′s unit/10 4 cell, P<0.01] were significantly decreased, while the level of intracellular superoxide anion (11.180±1.560 vs.6.146±1.007, P<0.01) and HUVECs apoptosis [75.0 (55.0, 100.0)% vs.0 (0, 0)%, P<0.01] were significantly increased in the eNOS shRNA group.Compared with the eNOS shRNA group, the content of endogenous NO (16.705±0.116 vs.2.690±0.420, P<0.01), the ratio of SOD1 dimer/monomer (7.3±2.0 vs.4.6±1.0, P<0.05) and the activity of SOD [(0.737±0.060) Carmen′s unit/10 4 cell vs.(0.432±0.254) Carmen′s unit/10 4 cell, P<0.05] were significantly increased, while the level of superoxide anion (6.897±1.648 vs.11.180±1.560, P<0.01) and the HUVECs apoptosis [0 (0, 0)% vs.75.0 (55.0, 100.0)%, P<0.01] were significantly decreased in the eNOS shRNA+ SNP group.Compared with the eNOS shRNA + SNP group, the ratio of SOD1 dimer/monomer (4.4±0.9 vs.7.3±2.0, P<0.05) and the activity of SOD [(0.214±0.084) Carmen′s unit/10 4 cell vs.(0.737±0.060) Carmen′s unit/10 4 cell, P<0.01] were significantly decreased, while the level of superoxide anion (10.917±1.552 vs.6.897±1.640, P<0.01) and the apoptosis level of HUVECs[63.6 (55.0, 90.0)% vs.0 (0, 0)%, P<0.01] were significantly increased in the eNOS shRNA+ SNP+ TCEP group.However, there was no significant difference in the NO content (16.112±0.926 vs.16.705±0.116, P>0.05). Conclusions:Endogenous NO could effectively antagonize the apoptosis of endothelial cells by increasing the cysteine-dependent SOD1 dimer/monomer ratio, enhancing SOD activity and inhibiting the accumulation of reactive oxygen species.
