ObjectiveTo study on the different therapeutic effects and potential mechanisms of Rhei Radix et Rhizoma(RH) before and after steaming with wine on constipation model mice. MethodsFifty-four male ICR mice were randomly divided into control group, model group, lactulose group(1.5 mg·kg-1), high, medium and low dose groups of RH and RH steaming with wine(PRH)(8, 4, 1 g·kg-1). Except for the control group, the constipation model was replicated by gavage of loperamide hydrochloride(6 mg·kg-1) in the other groups. After 2 weeks of modeling, each administration group was gavaged with the corresponding dose of drug solution, and the control and model groups were given an equal volume of normal saline, 1 time/d for 2 consecutive weeks. After administration, the feces were collected for 16S rRNA sequencing, the levels of gastrin(GAS), motilin(MTL), interleukin-6(IL-6), γ-interferon(IFN-γ) in the colonic tissue were detected by enzyme-linked immunosorbent assay(ELISA), the histopathological changes of colon were observed by hematoxylin-eosin(HE) staining, flow cytometry was used to detect the proportion changes of CD4+, CD8+ and regulatory T cell(Treg) in peripheral blood. ResultsCompared with the control group, the model group showed significantly decrease in fecal number in 24 h, fecal quality and fecal water rate(P<0.01), the colon was seen to have necrotic shedding of mucosal epithelium, localized intestinal glands in the lamina propria were degenerated, necrotic and atrophied, a few lymphocytes were seen to infiltrate in the necrotic area in a scattered manner, the contents of GAS and MTL, the proportions of CD4+, CD8+ and Treg were significantly reduced(P<0.01), the contents of IL-6 and IFN-γ were significantly elevated(P<0.05, P<0.01). Compared with the model group, the fecal number in 24 h, fecal quality and fecal water rate of high-dose groups of RH and PRH were significantly increased(P<0.05, P<0.01), the pathological damage of the colon was alleviated to varying degrees, the contents of GAS, MTL, IL-6 and IFN-γ were significantly regressed(P<0.05, P<0.01), and the proportions of CD4+ and CD8+ were significantly increased(P<0.01), although the proportion of Treg showed an upward trend, there was no significant difference. In addition, the results of intestinal flora showed that the number of amplicon sequence variant(ASV) and Alpha diversity were decreased in the model group compared with the control group, and there was a significant difference in Beta diversity, with a decrease in the relative abundance of Lactobacillus and an increase in the relative abundances of Bacillus and Helicobacter. Compared with the model group, the ASV number and Alpha diversity were increased in the high-dose groups of RH and PRH, and there was a trend of regression of Beta diversity to the control group, the relative abundance of Lactobacillus increased, and the relative abundances of Bacillus and Helicobacter decreased. ConclusionRH and PRH can improve dysbacteriosis, promote immune system activation, inhibit the release of inflammatory factors for enhancing the gastrointestinal function, which may be one of the potential mechanisms of their therapeutic effect on constipation.

Purpose:
Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms.
Materials and Methods:
Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A.
Results:
TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer.
Conclusion
TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

ObjectiveTo investigate the protective effect and mechanism of verbenalin on mouse mononuclear macrophage leukemia cells (RAW264.7) damaged by human coronavirus (HCoV)-229E infection, thereby providing experimental evidence for its development and application. MethodsRAW264.7 macrophages were infected with different concentrations of HCoV-229E to establish a coronavirus-induced macrophage injury model using the cell counting kit-8 (CCK-8) assay for assessing cell proliferation and viability. Cells were randomly divided into four groups: normal control, verbenalin group (125 μmol·L-1), model group (HCoV-229E), and HCoV-229E + verbenalin group (HCoV-229E + 125 μmol·L-1 verbenalin). Cell viability was measured using the CCK-8 assay, and the maximum non-toxic concentration (CC0), half-maximal cytotoxic concentration (CC50), half-maximal effective concentration (EC50), and selectivity index (SI) of verbenalin were calculated. Calcein/PI double staining was used to assess cell viability and cytotoxicity, and JC-1 staining was applied to evaluate changes in mitochondrial membrane potential (MMP). mito-Keima adenovirus labeling was used to assess mitophagy levels in each group. ResultsA macrophage infection model was successfully established by infecting RAW264.7 cells with the original concentration of HCoV-229E for 36 h. The CC0 of verbenalin was 125 μmol·L-1. The CC50 was 448.25 μmol·L-1. The EC50 against HCoV-229E-infected cells was 46.28 μmol·L-1, and the SI was 9.68. Compared with the normal group, the model group showed significantly reduced cell survival rate (P<0.01), increased cell death rate (P<0.01), decreased MMP (P<0.01), and suppressed mitophagy (P<0.01). In contrast, verbenalin treatment significantly improved cell survival rate (P<0.01), reduced cell death rate (P<0.01), alleviated MMP loss (P<0.01), and enhanced mitophagy levels (P<0.01) compared with the model group. ConclusionVerbenalin can enhance the survival rate of macrophages following HCoV-229E infection. The underlying mechanism may be associated with the activation of mitophagy, maintenance of MMP stability, and alleviation of mitochondrial damage.

ObjectiveThis paper aims to investigate the therapeutic effects of Jidesheng Sheyao tablets on varicella-zoster virus (VZV) and its associated postherpetic neuralgia (PHN) to provide experimental evidence for the clinical application and secondary development of Jidesheng Sheyao tablets. MethodsFifty-six guinea pigs were randomly divided into seven groups according to their body weight, namely the normal group, the model group, the positive control group, the high-dose group, medium-dose group, and low-dose group of Jidesheng Sheyao tablets (1.92, 0.96, 0.48 g·d-1), and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets (0.96 g·d-1 + 1.2 g·kg-1·d-1). The skin on the back of the guinea pigs in each group was depilated and then abraded with sandpaper. Except for the normal group, 200 μL of VZV solution was dropped on the damaged parts of the back of the guinea pigs in the other groups, and the infection lasted for 2 consecutive days. The drug administration started 2 hours after the infection on the first day and lasted for 7 days. The pathological changes of the back of the guinea pigs in each group were observed every day starting from the second day after the infection. On the 7th day, the guinea pigs were sacrificed by CO2 anesthesia. The locally infected skin was taken, and the viral DNA nucleic acid load was detected by real-time polymerase chain reaction (Real-time PCR). The pathological histology examination was carried out after hematoxylin-eosin (HE) staining. Seventy rats were randomly divided into seven groups according to their body weight, namely the normal group, the model group, the positive control group, the high-dose group, medium-dose group, and low-dose group of Jidesheng Sheyao tablets (1.08, 0.54, 0.27 g·d-1), and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets (0.54 g·d-1 + 1.2 g·kg-1·d-1). The rats in each group (except the normal group) were subcutaneously inoculated with 50 μL of VZV suspension between the web of the first and second fingers of the left forelimb. The skin on the back of the rats was depilated, and the drug administration started 2 hours after the infection and lasted for 10 days. The mechanical withdrawal threshold of the paws of the rats was detected by a Von Frey filament algometer before inoculation and on the 1st, 3rd, 6th, 8th, and 10th days after inoculation, and the thermal withdrawal reflex latency of the paws of the rats was detected by a hot and cold plate algometer. On the 10th day after the virus inoculation, the rats were anesthetized after the behavioral examination, and the dorsal root ganglia of the spinal cord and spinal cord segments were taken. The contents of substance P (SP), neurokinin (NK), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in the dorsal root ganglia of the spinal cord and spinal cord were detected by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with those in the normal group, the guinea pigs in the model group had obvious skin herpes lesions (P<0.01). The viral nucleic acid load was high (P<0.01), and there were disorganized subcutaneous cellular structures and obvious infiltration of inflammatory cells and cell necrosis (P<0.01). The mechanical withdrawal threshold of the paws and the thermal withdrawal reflex latency of the paws of the rats were significantly decreased (P<0.05), and the contents of NK, SP, TNF-α, and IL-1β in the dorsal root ganglia of the spinal cord and spinal cord of the rats were significantly increased (P<0.01). Compared with the model group, the high-dose and medium-dose groups of topical administration of Jidesheng Sheyao tablets and the group of oral administration combined with topical application could significantly improve the lesions such as skin redness and herpes of the guinea pigs caused by VZV infection (P<0.01), reduce the VZV viral nucleic acid load in the skin tissues of the guinea pigs (P<0.01), alleviate the degree of inflammatory cell infiltration and skin cell necrosis in the skin tissue (P<0.05), significantly increase the mechanical withdrawal threshold of the paws and the thermal withdrawal reflex latency of the paws of the rats (P<0.05), and decrease the contents of NK, SP, TNF-α, and IL-1β in the dorsal root ganglia of the spinal cord and spinal cord of the rats (P<0.01). ConclusionJidesheng Sheyao tablets demonstrated significant therapeutic effects on VZV-induced skin infections and postherpetic neuralgia (PHN), providing a promising candidate for the prevention and treatment of VZV infections.

ObjectiveTo evaluate the pharmacological effects of verbenalin on both in vitro and in vivo infection models of human coronavirus 229E (HCoV-229E) and to preliminarily explore the antiviral mechanism of verbenalin through proteomic analysis. MethodsIn vitro, the cell counting kit-8 (CCK-8) for cell proliferation and viability assessment was used to establish a model of HCoV-229E-induced injury in human lung adenocarcinoma cells(A549). A549 cells were divided into five groups: normal group, model group, and three verbenalin treatment groups (125, 62.5, and 31.25 μmol·L-1). The cell protective activity of verbenalin was evaluated through cell viability assay and immunofluorescence staining. In vivo, 30 BALB/c mice were randomly divided into normal group, model group, chloroquine group, and high-dose, low-dose verbenalin groups (40 and 20 mg·kg-1), with six mice per group. An HCoV-229E-induced mouse lung injury model was established to evaluate the therapeutic effects of verbenalin. Lung injury was assessed by detecting the lung index and lung inhibition rate. The severity of pulmonary inflammation cytokines was measured by enzyme-linked immunosorbent assay (ELISA), while the lung morphology and structure were analyzed by micro-computed tomography (Micro-CT). Hematoxylin and eosin (HE) staining was used to assess histopathological changes in lung tissue. Additionally, four-dimensional data-independent acquisition (4D-DIA) proteomics was employed to preliminarily explore the potential mechanisms of verbenalin in treating HCoV-229E-induced lung injury in mice, through differential protein expression screening, functional annotation, enrichment analysis, and protein-protein interaction network analysis. ResultsThe A549 cells were infected with HCoV-229E at the original viral titer for 36 hours to establish an in vitro infection model. The maximum non-toxic concentration of verbenalin was 125 μmol·L-1, and the half-maximal cytotoxic concentration (CC50) was 288.8 μmol·L-1. Compared with the normal group, the model group showed a significant decrease in cell viability (P<0.01), a significant increase in the proportion of dead cells (P<0.01), mitochondrial damage, and a significant reduction in mitochondrial membrane potential (P<0.01). After treatment with different concentrations of verbenalin (125, 62.5, and 31.25 μmol·L-1), cell viability was significantly increased (P<0.01), and the proportion of dead cells was reduced (P<0.01), with mitochondrial membrane potential restored (P<0.01). In vivo experiments further confirmed the therapeutic effect of verbenalin on HCoV-229E-infected mice. Compared to the normal group, the model group showed a significant increase in the lung index (P<0.01), severe lung tissue injury, lung volume enlargement, and a significant increase in the expression of inflammatory cytokines, including interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) (P<0.01). In contrast, in the verbenalin treatment groups, these pathological changes were significantly improved, with a reduction in the lung index (P<0.01), alleviation of lung tissue injury, reduced lung volume enlargement, and a significant decrease in inflammatory cytokine expression (P<0.01). Proteomics analysis revealed that, compared to the normal group, the model group showed enrichment in several antiviral immune-related signaling pathways, including the nuclear factor-κB (NF-κB) signaling pathway (P<0.05). Compared to the model group, the verbenalin treatment group showed enrichment in several signaling pathways related to inflammatory response and autophagy (P<0.05), suggesting that verbenalin may exert its antiviral and anti-inflammatory effects by regulating these pathways. ConclusionVerbenalin demonstrates significant therapeutic effects in both in vitro and in vivo HCoV-229E infection models, with its mechanism likely related to the NOD-like receptor protein 3 (NLRP3) inflammasome pathway and mitochondrial autophagy.
