Objective Differentially expressed genes in oral squamous cell carcinoma (OSCC) were subjected to bioinformatic and Mendelian randomization analyses to elucidate their prognostic significance in OSCC. Methods The TCGA database and dataset GSE138206 were used to screen the common differential genes of OSCC, and their relationship was analyzed by using Mendelian randomization. The prognostic value of differential genes was further analyzed by Cox risk regression. The biological function of genes with high prognostic value was further evaluated by single gene differential analysis. Results A total of 147 common differential genes were screened from the two databases. Results of two-sample Mendelian randomization showed that GREM2 was associated with the increased risk of OSCC. In addition, SH3BGRL2 was associated with a decreased risk of OSCC, and DKK1, CCL11, and HOXC6 were considered as independent prognostic markers of OSCC. The predicted results of DKK1 were consistent with the actual results. KEGG enrichment analysis indicated the potential involvement of DKK1 in arachidonic acid and linoleic acid metabolism. Furthermore, DKK1 showed positive correlations with Tgd and Th2 cells, while displaying negative associations with PDC, Cytotoxic cells, Mast cells, CD8 T cells, TFH cells, B cells, T cells, and Th17 cells. Conclusion GREM2 is associated with an increased risk of OSCC. DKK1 is highly expressed in OSCC and associated with poor prognosis, which may be involved in regulating the metabolism of arachidonic acid and linoleic acid and immune cell invasion in OSCC.

ObjectiveTo investigate the antidepressant effects and mechanisms of total flavonoids from Cuscutae Semen (TFCC) in the mouse model of chronic unpredictable mild stress (CUMS). MethodsFifty male 4-week-old ICR mice were randomized into five groups (n=10 per group): blank control, model, Cuscutae Semen decoction (10.2 g·kg-1·d-1), paroxetine (2.6 mg·kg-1·d-1), and TFCC (173.2 mg·kg-1·d-1). The other groups except the blank control group underwent chronic unpredictable mild stress (CUMS) for 4 weeks. Behavioral assessments were conducted post-modeling. Then, the model group received distilled water (10 mL·kg-1·d-1), while treatment groups were administrated with respective agents via oral gavage (10 mL·kg-1) for 4 weeks. Depression-like behaviors were evaluated by the sucrose preference test (SPT), forced swimming test (FST), and tail suspension test (TST). Hippocampal neuronal morphology was observed via hematoxylin-eosin staining, and apoptosis in the brain tissue was assessed via terminal- deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL). Enzyme-linked immunosorbent assay (ELISA) was employed to measure the hippocampal levels of inflammatory cytokines [interleukin (IL)-1β, IL-6, and TNF-α)] and neurotransmitters [5-hydroxytryptamine (5-HT), dopamine (DA), and brain-derived neurotrophic factor (BDNF)], while the reactive oxygen species (ROS) levels were quantified via the DCFH-DA probe. Real-time PCR was performed to measure the mRNA levels of NOD-like receptor protein 3 (NLRP3), apoptosis-associated Speck-like protein containing a CARD (ASC), cysteinyl aspartate-specific proteinase-1 (Caspase-1), IL-1β, and inducible nitric oxide synthase (iNOS). Western blot was employed to evaluate the protein levels of NLRP3, ASC, Caspase-1, uncoupling protein 2 (UCP2), and thioredoxin-interacting protein (TXNIP). ResultsCompared with the blank control group, the model group exhibited weight loss (P<0.01), reduced sucrose preference (P<0.01), prolonged immobility time in FST and TST (P<0.01), neuron disarrangement with nuclear pyknosis in hippocampal CA3 region, increased apoptosis in the brain tissue, elevated levels of IL-1β, IL-6, and TNF-α (P<0.01), declined levels of 5-HT, DA, and BDNF (P<0.01), increased ROS accumulation (P<0.01), upregulated mRNA levels of NLRP3, ASC, Caspase-1, IL-1β, and iNOS (P<0.01), down-regulated protein level of UCP2 (P<0.01), and up-regulated protein levels of NLRP3, ASC, Caspase-1, and TXNIP (P<0.01). Compared with the model group, the interventions restored sucrose preference (P<0.01), shortened immobility time (P<0.01), repaired hippocampal neuronal structure, reduced apoptosis, lowered the levels of inflammatory cytokines (P<0.01), restored the levels of neurotransmitters (P<0.01), alleviated ROS accumulation (P<0.01), downregulated the mRNA levels of NLRP3, ASC, Caspase-1, IL-1β, and iNOS (P<0.01), upregulated the protein level of UCP2 (P<0.01), and reduced the protein levels of NLRP3, ASC, Caspase-1, and TXNIP (P<0.01). Moreover, TFCC outperformed Cuscutae Semen decoction in ameliorating depressive behaviors. TFCC excelled in neuronal repair, neurotransmitter regulation, anti-inflammatory effects, and modulation of the UCP2/TXNIP/NLRP3 pathway (P<0.05). ConclusionTFCC modulates the hippocampal UCP2/TXNIP/NLRP3 pathway to inhibit inflammasome activation, reduce oxidative stress, restore neurotransmitters, thus suppressing neuronal apoptosis and promoting the rearrangement and morphology recovery of hippocampal cells. It outperforms Cuscutae Semen decoction in the antidepressant efficacy.

ObjectiveTo investigate the protective effects and mechanisms of Bushen Zhuyun prescription (BSZY) on abortion rats with kidney deficiency-corpus luteum inhibition syndrome. MethodsAn abortion rat model with kidney deficiency-corpus luteum inhibition syndrome was constructed. Pregnant mice aged 8-10 weeks were randomly divided into a control group (Control), a model group (Model), low-dose BSZY (BSZY-L), medium-dose BSZY (BSZY-M), and high-dose BSZY (BSZY-H) groups (2.57, 5.14, 10.28 g·kg-¹), and a Zishen Yutai Pill (ZSYT) group (1.575 g·kg-¹). Hematoxylin-eosin (HE) staining was used to evaluate histopathological changes in ovarian and decidual tissue of rats in each group. Enzyme-linked immunosorbent assay (ELISA) was employed to measure levels of estrogen (E₂), progesterone (P), luteinizing hormone (LH), prolactin (PRL), and follicle-stimulating hormone (FSH) in serum. The candidate targets of BSZY were obtained from the Traditional Chinese Medicine System Pharmacology Platform (TCMSP) and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0 databases, while disease targets for recurrent spontaneous abortion (RSA) were retrieved from GeneCards, DrugBank, Online Mendelian Inheritance in Man (OMIM), and Therapeutic Target Database (TTD). The intersection targets were identified by the Venny 2.1.0 platform. Pathway enrichment analysis was conducted based on the Metascape database to predict the potential mechanisms of BSZY. Additionally. Western blot was used to verify the effects of BSZY on the expression of estrogen receptor (ERα), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) and explore its protective mechanism on RSA rats. ResultsCompared with the control group, the model group exhibited significantly decreased uterine, ovarian, and embryonic wet weights (P<0.05, P<0.01), with an abortion rate of 57.18%. The ovarian tissue showed varying degrees of reduction in primordial follicles, primary follicles, mature follicles, and corpora lutea, along with a large number of atretic follicles. The endometrium was thinner, and decidual tissue exhibited cellular edema and disorganized arrangement. In contrast, compared with the model group, the BSZY groups at all doses and the ZSYT group demonstrated increased uterine, ovarian, and embryonic wet weights, along with a reduced abortion rate. The number of primordial follicles, primary follicles, mature follicles, and corpora lutea increased, while atretic follicles decreased. The endometrium thickened, and decidual tissue displayed normal cellular structure with tight arrangement. Additionally, the model group showed significantly decreased levels of E₂, P, PRL, and FSH in serum (P<0.05, P<0.01), along with a decreasing trend in LH level. In contrast, the BSZY groups at all doses exhibited significantly elevated levels of E₂, P, LH, PRL, and FSH in serum (P<0.05, P<0.01). Network pharmacology predictions suggested that BSZY may exert protective effects against abortion in rats by activating the ERα/PI3K/Akt signaling pathway. Western blot results confirmed that BSZY significantly upregulated the expression of ERα, PI3K, and p-Akt proteins (P<0.05, P<0.01). ConclusionBSZY has a protective effect on the abortion rats with kidney deficiency-corpus luteum inhibition syndrome, possibly by activating the ERα/PI3K/Akt signaling pathway to reduce ovarian apoptosis and regulate endocrine function, thereby lowering the abortion rate.

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.

Objective To investigate the role of hydrogen therapy in reducing radiation-induced lung injury and the specific mechanism. Methods Forty C57BL/6 mice were randomly divided into four groups: normal control group, model group, hydrogen therapy group I, and hydrogen therapy group II. A mouse model of radiation-induced lung injury was established. The pathological changes in the lung tissue of the mice were examined with HE staining. Immunofluorescence staining was used to detect the expression of surface markers of M1 and M2 macrophages to observe macrophage polarization. The expression of interleukin (IL)-6, tumor necrosis factor-α (TNF-α), and IL-10 in the lung tissue was measured by immunohistochemistry. The expression of nuclear factor-kappa B (NF-κB) p65 and phosphorylated NF-κB (P-NF-κB) p65 was measured by Western blot. Results HE staining showed that compared with the control group, the model group exhibited alveolar septal swelling and thickening, vascular dilatation and congestion, and inflammatory cell infiltration in the lung tissue; the hydrogen groups had significantly reduced pathological damage and inflammatory response than the model group, with more improvements in hydrogen group II than in hydrogen group I. Immunohistochemical results showed that compared with those in the control group, the levels of the inflammatory cytokines IL-6 and TNF-α were significantly increased in the model group; the hydrogen groups showed significantly decreased IL-6 and TNF-α levels and a significantly increased level of the anti-inflammatory factor IL-10 than the model group, which were more marked in hydrogen group II than in hydrogen group I. Immunofluorescence results showed that compared with the control group, the expression of the surface marker of M1 macrophages in the model group was significantly upregulated; the hydrogen groups showed significantly downregulated M1 marker and significantly upregulated M2 marker, and hydrogen group II showed significantly increased M2 marker compared with hydrogen group I. Western blot results showed that compared with that in the control group, the ratio of P-NF-κB p65/NF-κB p65 in the model group was significantly increased; the P-NF-κB p65/NF-κB p65 ratio was significantly reduced in the hydrogen groups than in the model group, and was significantly lower in hydrogen group II than in hydrogen group I. Conclusion Hydrogen inhalation therapy may reduce the inflammatory response of radiation-induced lung injury by inhibiting the NF-κB signaling pathway to promote the polarization of the macrophage M1 subtype to the M2 subtype.
