ObjectiveTo investigate the effects of jujuboside A (JuA) on the learning and memory abilities and histopathological changes in the rat model of vascular cognitive impairment (VCI) and explore the potential mechanisms by which JuA treats VCI. MethodsA total of 50 male SPF-grade SD rats were randomized into a sham operation group (n=10), a blank control group (n=10), and a modeling group (n=30). The rats in the modeling group underwent bilateral carotid artery ligation (2-VO) for the modeling of VCI. After stabilization, the VCI rats were randomized into model, JuA (20 mg·kg-¹), and donepezil (0.45 mg·kg-¹) groups. After 4 weeks of gavage, the novel object recognition and Morris water maze tests were conducted to evaluate the learning and memory abilities of rats. Nissl staining was employed to evaluate the morphology and number of hippocampal neurons. Real-time PCR was employed to measure the mRNA levels of glycogen synthase kinase-3β (GSK-3β), cAMP response element-binding protein (CREB), B cell lymphoma-2 (Bcl-2), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) in the hippocampal tissue. Western blot was employed to quantify the protein levels of GSK-3β, p-GSK-3β, p-CREB, Bcl-2, PI3K, p-PI3K, Akt, and p-Akt in the hippocampal tissue. ResultCompared with the sham operation group, the model group exhibited declines in the learning and memory abilities (P<0.01), neuronal damage and decreased neurons in the hippocampal CA1 region (P<0.01), up-regulation in the mRNA level of GSK-3β (P<0.01), and down-regulation in the mRNA levels of PI3K, Akt, CREB, and Bcl-2, as well as the protein levels of p-PI3K, p-Akt, p-GSK-3β, p-CREB, and Bcl-2 (P<0.01). In comparison to the model group, both the JuA and donepezil groups demonstrated improvements in the learning and memory abilities (P<0.05, P<0.01), with reduced neuronal damage and increased neurons (P<0.05, P<0.01). In addition, the two groups showed down-regulation in the mRNA level of GSK-3β (P<0.01) and up-regulation in the mRNA levels of PI3K, Akt, CREB, and Bcl-2 and the protein levels of p-PI3K, p-Akt, p-GSK-3β, p-CREB, and Bcl-2 (P<0.05, P<0.01). There were no statistically significant differences between the blank control and sham operation groups in terms of the learning and memory abilities, neuron count, and mRNA and protein levels of PI3K/Akt/GSK-3β pathway-related factors. ConclusionJuA can ameliorate the cognitive impairment in the rat model of VCI by activating the PI3K/Akt signaling pathway, reducing the apoptosis of hippocampal neurons, and alleviating the hippocampal neuronal damage.

Objective To investigate the effect and mechanism of the signal transducer and activator of transcription 3 (STAT3) inhibitor Stattic on the rejection of mouse heart allograft. Methods BALB/c mice (donors) were used to transplant skin onto C57BL/6 mice (recipients). Four weeks later, memory CD4+ T cells (CD4+Tm) were isolated from the recipient mice's spleens. Mixed lymphocyte reaction experiment was conducted with C57BL/6 mouse splenocytes and CD4+Tm, and the EdU method was used to detect the effect of Stattic on CD4+Tm cell proliferation. A C57BL/6 mouse heart transplant (HTx) model was constructed, and the experiment was divided into four groups: Non-HTx group, HTx group, Tm/HTx group, and Tm/HTx+Stattic group. The survival of heart allografts in mice was observed daily. Hematoxylin-eosin staining was used to observe the histopathology of the heart allografts. Real-time fluorescent quantitative polymerase chain reaction was used to detect the expression levels of interferon (IFN)-γ, interleukin (IL)-2, IL-10, and transforming growth factor-β1 (TGF-β1) messenger RNA (mRNA) in the heart allografts. Enzyme-linked immunosorbent assay was used to detect the levels of IFN-γ, IL-2, IL-10, and TGF-β1 in the serum. Flow cytometry was used to detect the levels of CD4+Tm (CD4+CD44+CD62L+) in splenic lymphocytes. And Western blotting was used to detect the expression levels of STAT3 and p-STAT3 proteins in the heart allografts. Results When the concentration of Stattic exceeded 2.5 μmol/L, it could inhibit the proliferation of CD4+Tm cells. Compared with the HTx group, the Tm/HTx group showed shorter survival time of heart grafts, more severe histopathological damage, increased serum IFN-γ and IL-2 levels, decreased IL-10 and TGF-β1 levels, increased relative expression of IFN-γ and IL-2 mRNA, decreased relative expression of IL-10 and TGF-β1 mRNA in the heart allografts, increased proportion of CD4+Tm in splenic lymphocytes, and increased p-STAT3/STAT3 ratio in the heart allografts (all P<0.05). Compared with the Tm/HTx group, the Tm/HTx+Stattic group showed longer survival time of heart grafts, less severe histopathological damage, decreased serum IFN-γ and IL-2 levels, increased IL-10 and TGF-β1 levels, decreased relative expression of IFN-γ and IL-2 mRNA, increased relative expression of IL-10 and TGF-β1 mRNA in the heart allografts, decreased proportion of CD4+Tm in splenic lymphocytes, and decreased p-STAT3/STAT3 ratio in the heart allografts (all P<0.05). Conclusions Stattic may prolong the survival time of mouse heart allografts, and its mechanism may be related to the inhibition of CD4+Tm- mediated acute rejection.

OBJECTIVE To investigate the effects of galangin (GLA) on autophagy and apoptosis of chondrocytes in knee osteoarthritis (KOA) rats by regulating the adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR)/UNC-51-like kinase 1 (ULK1) signaling pathway. METHODS KOA rat model was constructed and separated into model group, L-GLA, M-GLA, H-GLA groups [subcutaneous injection of 100, 200, 400 μg/kg GLA], GLA+Compound C group [subcutaneous injection of 400 μg/kg GLA+0.2 mg/kg AMPK inhibitor Compound C], with 10 rats in each group. Additionally, 10 normally fed rats were selected as the sham operation group. After the last medication, the degree of knee joint swelling of rats in each group was detected; the pathology of knee joints in KOA rats was observed. The serum expressions of matrix metalloproteinase 13 (MMP-13) and interleukin-1β (IL-1β) in KOA rats were detected; the autophagy of chondrocytes in KOA rats was observed; the chondrocyte apoptosis in KOA rats was detected; the phosphorylation of AMPK/mTOR/ULK1 pathway-related proteins in cartilage tissue of knee joint were detected in rats. RESULTS Compared with the sham operation group, the arrangement of articular chondrocytes in the model group was disordered, with nuclear pyknosis and severe fibrosis of the articular cartilage layer, accompanied by a large amount of inflammatory cell infiltration; the degree of joint swelling, the number of autophagic vacuoles and apoptosis rate of chondrocytes, serum levels of MMP-13 and IL-1β, and the phosphorylation of mTOR protein in cartilage tissue of knee joint were all increased significantly (P<0.05), while the phosphorylation of AMPK and ULK1 protein were all decreased significantly in cartilage tissue of knee joint (P<0.05). Compared with the model group, L- GLA, M-GLA, H-GLA groups showed significant improvement in joint cartilage injury and reduced infiltration of inflammatory cells in rats. The above quantitative indicators were significantly reversed in a dose-dependent manner,except the number of autophagic vacuoles increased significantly (P<0.05). Compared with the H-GLA group, the GLA+ Compound C group showed aggravated cartilage tissue of joint cartilage injury and inflammatory cell infiltration in rats, and the above quantitative indicators were reversed significantly (P<0.05). CONCLUSIONS GLA can promote autophagy and inhibit apoptosis of chondrocytes in KOA rats, the mechanism of which may be associated with activating AMPK/mTOR/ULK1 signaling pathway.

Objective:
To explore the relationship of family function with sleep and externalizing problem behaviors of preschool children, so as to provide a guidance for externalizing problem prevention and intervention among preschool children.
Methods:
From October 2023 to January 2024, a convenience sampling method was used to select 5 138 preschool children from kindergartens in 8 districts of Wuhan City, Hubei Province. Parents completed the survey for Family Adaptability and Cohesion Scale, children s sleep habits and Child Behavior Checklist (CBCL). Spearman correlation analysis was used to examine the correlation of family function with scores of sleep quality and externalizing problem behaviors among preschool children. A mediation model analysis and bootstrap test were conducted to further investigate the mediating role of sleep quality between family function and externalizing problem behaviors. Mplus 8.7 software was used for latent profile analysis of family function.
Results:
The reported rates of poor sleep quality and externalizing problem behaviors among preschool children were 11.8% ( n =607), 20.0% ( n =1 026). The relevant analysis results showed that family function was negatively correlated with sleep quality and externalizing problem behaviors ( r = -0.20, -0.23), and sleep quality was positively correlated with externalizing problem behaviors ( r =0.27) ( P <0.01). The mediation effect test showed that family function negatively predicted externalizing problem behaviors ( β =-0.079) and sleep quality ( β = -0.075), while sleep quality positively predicted externalizing problem behaviors ( β =0.215) ( P <0.01). The latent profile analysis results showed that family function could be classified into 4 categories: high family function group (23.01%), upper middle family function group (44.65%), moderate family function group (26.24%) and low family function group (6.11%). Compared to high family function, the other three categories significantly positively predicted externalizing problem behaviors, and the mediating effects of sleep quality on different categories of family function were statistically significant [upper middle family function: mediation effect value was 0.022 (95% CI =0.004-0.041) and direct effect value was 0.329 (95% CI =0.263-0.396); middle family function: mediation effect value was 0.087 (95% CI =0.063-0.115) and direct effect value was 0.491 (95% CI =0.416-0.565); low family function: mediation effect value was 0.144 (95% CI =0.107-0.185) and direct effect 0.621 (95% CI =0.503-0.740)] ( P < 0.05 ).
Conclusion
Family function negatively predicts the externalizing problem behaviors of preschool children, and sleep quality plays a partial mediating role.

ObjectiveUltra performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS) coupled with network pharmacology and molecular docking was utilized to explore the efficacy and mechanism of action of Ermiao Situ decoction on rats with damp-heat eczema. MethodsA rat model of damp-heat eczema was established by artificial climate chamber intervention combined with sensitization induction by dinitrochlorobenzene (DNCB), and it was randomly divided into the normal group, the model group, the medium- and high-dose groups of Ermiao Situ decoction (3.40 g·kg-1 and 6.80 g·kg-1), and the prednisone acetate group (2.51 mg·kg-1), with eight rats in each group, totalling 46 rats, of which six rats were tested with the drug-containing serum. The chemical analysis of drug-containing serum from rats was carried out by UPLC-Q-TOF-MS/MS, combined with network pharmacology for the prediction of key components, core targets, and signaling pathways, and molecular docking experiments were performed by CB-Dock2 online website. The pharmacological effects of Ermiao Situ decoction in the treatment of damp-heat eczema were investigated by epitaxial indexes combined with the pathologic tissue staining method. The serum levels of gastrin (GAS), interleukin-4 (IL-4), and interleukin-13 (IL-13) were measured by enzyme-linked immunosorbent assay (ELISA). Interleukin-6 (IL-6), Janus kinase 1 (JAK1), phosphorylated (p)-JAK1, signal transduction and activation of transcription factor 3 (STAT3), and p-STAT3 protein expression level was determined by Western bolt. ResultsA total of 19 active ingredients were detected in drug-containing serum samples of rats, which were predicted to act on 198 targets for the treatment of damp-heat eczema, among which the key ingredients included rhodopsin, huangpai alkaloids, and quercetin, and the main core targets included STAT3, tumor necrosis factor (TNF), and IL-6, which were mainly involved in the cancer signaling pathway, phosphatidylinositol 3-kinase (PI3K)/protein kinase (Akt) signaling pathway, T helper 17 (Th17) cell differentiation signaling pathway, and JAK/STAT signaling pathway. The molecular docking results suggested that the key components had strong binding activities with the core targets IL-6, JAK1, and STAT3 in the JAK/STAT signaling pathway. The results of animal experiments showed that compared with those in the normal group, rats in the model group were depressed. They had loose hair, loose stools, epidermal oozing, vesiculation, and generation of thick scabs in the form of scales, decreased body weight, increased anus temperature and water intake, and increased indexes of the spleen, thymus gland, and stomach (P<0.05, P<0.01), and the lesion tissue could be seen to be hyperkeratotic, with the aggregation of inflammatory cells and nonsignificant separation of epidermis and dermis. The gastric mucosa was thinned, deficient, and structurally disorganized, and obvious inflammatory cell aggregation was seen. The levels of GAS, IL-4, and IL-13 in serum were significantly reduced (P<0.05, P<0.01), and the protein expression levels of IL-6, JAK1, p-JAK1, and p-STAT3 in the lesion tissue were significantly increased (P<0.05, P<0.01). Compared with those in the model group, rats in each administration group had stable mental states, formed feces, a clean perianal area, and basically normal epidermis. Only a small amount of scaly scabs existed, and the rats had body weight increased, with decreased anal temperature and water intake, as well as decreased spleen, thymus, and gastric indexes (P<0.05, P<0.01). Epidermal thickness was decreased, and epidermal and dermal separation boundaries were obvious, but hyperkeratotic and accumulation of inflammatory cells could still be seen. The thickness of gastric mucosa increased, and the structure was restored to varying degrees. The levels of GAS, IL-4, and IL-13 content in the serum of rats were increased to varying degrees, and the protein expression levels of IL-6, JAK1, p-JAK1, and p-STAT3 in the dermal lesion tissue were significantly decreased (P<0.05, P<0.01). ConclusionErmiao Situ decoction may exert therapeutic effects on rats with damp-heat eczema by modulating the JAK/STAT signaling pathway.

Objective To explore the correlation between serum ferritin and the risk of metabolic syndrome, and to provide evidence for the prevention and control of metabolic syndrome. Methods Data was from the Jiang'an District survey data of the Chinese Resident Nutrition and Health Monitoring Project in 2022. A total of 399 adult residents were selected as the study subjects and the investigation was performed by questionnaire, physical examination and biochemical testing. Statistical analysis was conducted by SAS 9.4 software, and the association between serum ferritin and metabolic syndrome was analyzed by using multivariate logistic regression. Results The prevalence of metabolic syndrome in the study population was 43.61%, and 39.04% after standrdization. With the increase of serum ferritin levels, the prevalence of metabolic syndrome gradually increased (P<0.05). Serum ferritin was positively correlated with WC, DBP, TG, FPG, hsCRP, and HbA1c, while negatively correlated with HDL-C (P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, female serum ferritin was positively correlated with the prevalence of metabolic syndrome (OR=3.59,95% CI:1.72-7.46); however, male serum ferritin level was not correlated with the prevalence of metabolic syndrome (OR=2.02,95% CI:0.76-3.40). Conclusion The prevalence of metabolic syndrome among residents in Jiang'an District is relatively high. Serum ferritin is associated with various components of metabolic syndrome, and the high serum ferritin level in women is associated with a higher risk of metabolic syndrome.
8.Bioethics and dignity in the capability approach
Chinese Medical Ethics 2025;38(3):352-356
Dignity is a core concept in bioethics. With the development of emerging life science technologies, maintaining human dignity has become the main reason for restricting the use and development of these new technologies. In bioethics, this dignity-based conservatism manifests in two forms, namely religious conservatism and secular conservatism. However, they face some difficulties respectively. Compared with conservatism, the concept of dignity advocated by the capability approach can not only avoid these difficulties but also provide a reasonable justification for people’s rational utilization and development of emerging biotechnologies.

OBJECTIVE To investigate the effect and mechanism of bumetanide on lung injury in chronic obstructive pulmonary disease (COPD) model rats. METHODS COPD rat model was induced by lipopolysaccharide, and they were randomly divided into model group (COPD group), bumetanide low-dose and high-dose groups (Bumetanide-L group, Bumetanide-H group), bumetanide high-dose+Yes-associated protein/transcriptional coactivator containing PDZ-binding motif (YAP/TAZ) signaling pathway activator group (Bumetanide-H+PY-60 group), with 12 rats in each group. Another 12 normal rats were selected as normal control group (Control group). Thirty minutes before modeling, bumetanide/normal saline was inhaled or/and PY-60/ normal saline was injected into the tail vein. On the next day after the completion of modeling and drug administration, the pulmonary function index of the rats in each group was measured [forced expiratory volume in 0.3 seconds (FEV0.3), forced vital capacity (FVC), peak expiratory flow (PEF), FEV0.3/FVC]. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-1β in bronchoalveolar lavage fluid (BALF) were determined; the pathological morphology of lung tissue and degree of pulmonary fibrosis were observed. The expression levels of transforming growth factor- β (TGF- β), α -smooth muscle actin (α-SMA) and TAZ protein as well as the phosphorylation of YAP protein in lung tissues were detected. RESULTS Compared with COPD group, the pathological injury of lung tissue in Bumetanide-L and Bumetanide-H groups was alleviated; the exfoliation of lung epithelial cells, tube wall thickening and the degree of pulmonary fibrosis were alleviated; inflammatory cell infiltration was reduced, and blue collagen deposition was reduced; FEV0.3, FVC, FEV0.3/FVC and PEF were significantly increased, while the lung injury score, levels of TNF-α, IL-6, IL-1β, expression levels of TGF-β, α-SMA and TAZ protein and the phosphorylation of YAP protein were significantly decreased (P<0.05). PY-60 could significantly reverse the improvement effects of bumetanide on above indexes (P<0.05). CONCLUSIONS Bumetanide can alleviate lung injury, inflammatory response and pulmonary fibrosis in COPD rats, and its mechanism is related to inhibiting YAP/TAZ signaling pathway.
