OBJECTIVE To investigate the effects and mechanism of the Yishen paidu formula on renal fibrosis in rats with chronic renal failure (CRF) through the reactive oxygen species (ROS)/thioredoxin-interacting protein (TXNIP)/NOD-like receptor thermal protein domain associated protein 3 (NLRP3) pathway. METHODS Rats were randomly divided into control group, model group, Yishen paidu formula low-dose (Yishen paidu formula-L) group, Yishen paidu formula high-dose (Yishen paidu formula- H) group, Yishen paidu formula-H+pcDNA-NC group, and Yishen paidu formula-H+ pcDNA-TXNIP group, with 10 rats in each group. Except for control group, all other rats were fed a diet containing 0.5% adenine to establish a CRF model; the rats were then administered corresponding drugs or normal saline intragastrically or via tail vein, once daily, for 8 consecutive weeks. After the last administration, the levels of serum creatinine (Scr), blood urea nitrogen (BUN), ROS, superoxide dismutase (SOD), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-1β were measured in each group. Pathological changes in renal tissue were observed, and the protein expression levels of Collagen Ⅲ, α-smooth muscle actin (α-SMA), transforming growth factor-β1 (TGF-β1), TXNIP and NLRP3 in renal tissue were detected. RESULTS Compared with model group, the renal histopathological damage and fibrosis of rats in Yishen paidu formula-L group and Yishen paidu formula-H group were significantly alleviated. The levels of Scr, BUN, ROS, MDA, TNF- α, IL-6 and IL-1β, and the protein expressions of Collagen Ⅲ, α-SMA, TGF-β1, TXNIP and NLRP3 were significantly decreased, while SOD levels were significantly increased (P<0.05). Moreover, the changes were more pronounced in the Yishen paidu formula-H group (P<0.05). Compared with Yishen paidu formula-H+pcDNA-NC group, above indexes of rats in Yishen paidu formula-H+pcDNA-TXNIP group were reversed significantly (P<0.05). CONCLUSIONS Yishen paidu formula can inhibit renal fibrosis in CRF rats by suppressing the ROS/TXNIP/NLRP3 pathway.

Objective:
To explore the relationship between snack consumption and depressive symptoms in first year junior high school students with different left behind experiences in Yunnan Province, so as to provide a basis for improving depressive symptoms among first year junior high school students with different left behind experiences.
Methods:
From October to December 2022,a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County) in Yunnan Province for a questionnaire survey. The Chinese version of Depression Anxiety Stress Scale-21 was applied to assess depressive symptoms in first year junior high school students, and snack consumption was collected by employing food frequency questionnaire. The generalized linear model was used to analyze the association between first year junior high school students snack consumption and depressive symptoms, and the analysis was stratified according to left behind experience.
Results:
The detection rates of depressive symptoms among firstyear junior high school students with and without left behind experience were 36.25% and 26.91%, respectively. After controlling for confounding variables, the generalized linear model analysis showed that sweet snacks ( β=0.16, 95%CI =0.07-0.25), fast food ( β=0.14, 95%CI =0.04-0.23) and carbonated drinks ( β=0.09, 95%CI =0.01-0.17) of first year junior high school students with left behind experience (all P <0.05). Compared with those without such behavior, the risk of depressive symptoms was higher in consumption of fast food ( β=0.13, 95%CI =0.07-0.18) and carbonated drinks ( β=0.10, 95%CI =0.06-0.15)among first year junior high school students without left behind experience (both P <0.05).
Conclusion
Snack consumption among first year junior high school students in Yunnan may increase the risk of developing depressive symptoms, while first year junior high school students with left behind experience may have a greater risk of developing depressive symptoms.

ObjectiveTo investigate the imaging features of calcium salt deposition and serological markers in patients with alveolar echinococcosis through a retrospective analysis, as well as independent risk factors for the degree of calcium salt deposition in lesions, and to provide a basis for assessing disease process. MethodsA retrospective analysis was performed for the imaging and clinical data of 107 patients with alveolar echinococcosis who were admitted to The First Affiliated Hospital of Shihezi University from December 2023 to June 2025, and according to the volume of calcium salt deposition, they were divided into non-deposition group with 16 patients, mild deposition group with 52 patients, moderate deposition group with 16 patients, and severe deposition group with 23 patients. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups, and the χ2 test or Fisher’s exact test was used for comparison of categorical data between groups. The four groups were further combined into the low deposition group (no/mild deposition) and the high deposition group (moderate/severe deposition). A binary logistic regression analysis was used to investigate the independent influencing factors for calcium salt deposition, and a predictive model was established. The receiver operating characteristic (ROC) curve was used to assess the predictive performance of the model, and the Bootstrap method was used for internal validation. ResultsThere were significant differences between the four groups in sex distribution, involvement of other sites, white blood cell count, lymphocyte percentage, fibrinogen, uric acid, sodium ion, chloride ion, and calcium ion (all P<0.05). The univariate analysis showed that there were significant differences between the four groups in sex, involvement of other sites, white blood cell count, lymphocyte percentage, fibrinogen, alanine aminotransferase, albumin, creatinine, uric acid, sodium ion, chloride ion, and calcium ion (all P<0.1). The multi-collinearity diagnosis showed that the VIF values for all continuous variables ranged from 1.104 to 1.760, suggesting that collinearity did not affect modeling. An ordinal logistic regression model was established based on sex, involvement of other sites, calcium ion, lymphocyte percentage, and uric acid. The multivariate analysis showed that lymphocyte percentage (odds ratio [OR]=1.106, 95% confidence interval [CI]: 1.041 — 1.174, P=0.001) and blood calcium level (OR=0.005, 95%CI: 0.000 —0.230, P=0.007) were independent influencing factors for the degree of calcium salt deposition. The regression equation was established as Logit(P)=8.231 + 0.100 × lymphocyte percentage -5.344 × calcium ion. The ROC curve analysis showed that the model had an area under the ROC curve of 0.716, with a Youden index of 0.353, a sensitivity of 1.000, and a specificity of 0.353. The Hosmer-Lemeshow test showed that the model had poor calibration (χ2=20.688, P=0.008). The Bootstrap method with 1000 repeated samples showed that the estimated values of lymphocyte percentage (OR=1.106, 95%CI: 1.049 — 1.186, P=0.002) and calcium ion (OR=0.005, 95%CI: 0.000 — 0.214, P=0.010) were consistent with the original model, and the confidence intervals did not include 1, which further supported the reliability of the model. ConclusionBoth lymphocyte percentage and blood calcium level are independent influencing factors for calcium salt deposition in alveolar echinococcosis, and the degree of calcium salt deposition in alveolar echinococcosis lesions increases with the reduction in blood calcium level and the increase in lymphocyte percentage.

ObjectiveTo investigate the anti-inflammatory and antioxidant effects of baicalin for treating chronic obstructive pulmonary disease (COPD) in rats and decipher the molecular mechanisms via the nuclear factor-kappa B (NF-κB)/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. MethodsSixty SPF-grade male Sprague-Dawley rats were randomly assigned into six groups: normal control, COPD model, low-dose baicalin, medium-dose baicalin, high-dose baicalin, and budesonide. The normal control group received no treatment, whereas COPD was modeled in other groups with a combined modeling approach involving intratracheal lipopolysaccharide instillation and passive cigarette smoke exposure. The model establishment was evaluated through behavioral observation combined with pathological examination. Hematoxylin-eosin (HE) staining was performed to assess histopathological changes in the lung. Serum levels of inflammatory cytokines [interleukin (IL)-6, IL-8, IL-17, IL-22, tumor necrosis factor (TNF)-α, and transforming growth factor (TGF)-β)], reactive oxygen species (ROS), and vascular endothelial growth factor (VEGF) were quantified by enzyme-linked immunosorbent assay (ELISA). Meanwhile, the levels of IL-6, IL-17, and IL-22 in the bronchoalveolar lavage fluid (BALF) and IL-10, IL-22, and TNF-α in the lung tissue were measured via ELISA. Immunohistochemistry (IHC) was employed to detect the expression of histone deacetylase 2 (HDAC2) and Nrf2. Western blot was performed to evaluate the expression of phosphoinositide 3-kinase (PI3K), protein kinase B (Akt), glucocorticoid receptor (GR), NF-κB, HDAC2, and Nrf2 in the lung tissue. Additionally, real-time PCR was conducted to assess the mRNA levels of PI3K, Akt, HDAC2, Nrf2, GR, and NF-κB in the lung tissue. ResultsHE staining revealed that the airway mucosal epithelium in the COPD model group appeared extensive shedding, structural disorganization, and diffuse infiltration of inflammatory cells within the lumen. And goblet cells showed compensatory proliferation with pathological hypertrophy of mucus glands. In contrast, inflammatory infiltration and alveolar overdistension were significantly alleviated in the medium- and high-dose baicalin groups. The COPD model group exhibited mucus plug formation within the terminal bronchioles, along with fibrotic narrowing of the bronchial wall. Moreover, the smooth muscle bundles of the bronchial wall were hypertrophic, with concomitant collagen deposition. Progressive dissolution and rupture of alveolar septa were observed, leading to the formation of abnormally enlarged air-filled cavities. However, the bronchial wall structure was largely restored with only mild thickening of the smooth muscle layer in the baicalin groups. Compared with the COPD model group, the medium- and high-dose baicalin groups showed declined ROS and VEGF levels (P<0.05), and all the baicalin groups presented lowered levels of IL-6, IL-8, IL-17, IL-22, TGF-β, and TNF-α and elevated level of IL-10 (P<0.05). Baicalin upregulated the protein levels of HDAC2, Nrf2, GR, PI3K, and Akt, while suppressing the protein level of NF-κB (P<0.05). Furthermore, baicalin increased the mRNA levels of Nrf2 and GR while down-regulating the mRNA level of NF-κB (P<0.05). ConclusionBaicalin exerts anti-inflammatory and antioxidant effects by inhibiting the pro-inflammatory factor NF-κB while enhancing the expression of the anti-inflammatory factor HDAC2 and activating the antioxidant factor Nrf2, thereby alleviating the lung tissue damage in COPD rats. The therapeutic effects of baicalin may be closely associated with its regulatory role in the NF-κB/Nrf2 signaling pathway.

OBJECTIVE To explore the in vitro and in vivo inhibitory effects and mechanism of metformin on the malignant biological behavior of esophageal squamous cell carcinoma (ESCC) cells by the hypoxia inducible factor-1α (HIF-1α)/interleukin-8 (IL-8) signaling pathway. METHODS Human ESCC TE1 cells were assigned into blank group, metformin low-, medium-, and high-dose groups (0.5, 1, 2 mmol/L), IDF-11774 (HIF-1α inhibitor) group (20 μmol/L), and high-dose metformin+HIF-1α activator dimethyloxalylglycine (DMOG) group. After 24 h treatment, cell proliferation [measured by the positive rate of 5-ethynyl- 2′-deoxyuridine (EdU) and optical density at 450 nm (OD450 value)], apoptosis, invasion and migration as well as mRNA expressions of proliferating cell nuclear antigen (PCNA), Bcl-2 interacting mediator of cell death (Bim), migration and invasion enhancer 1 (MIEN1), and matrix metalloproteinase-9 (MMP-9), and protein expressions of HIF-1α and IL-8 in the cells were detected. The xenograft tumor model of nude mice was established. Thirty nude mice were randomly divided into blank group, metformin low-, medium-, and high-dose groups (i.g. administration of metformin 62.5, 125, 250 mg/kg+i.p. administration of equal volume of normal saline), IDF-11774 group (i.g. administration of 50 mg/kg IDF-11774+i.p. administration of equal volume of normal saline) and high-dose metformin+DMOG group (i.g. administration of metformin 250 mg/kg+i.p. administration of DMOG 250 mg/kg), with 5 mice in each group. They were given relevant medicine, once a day, for 4 consecutive weeks; the mass and volume of the tumor and protein expressions of HIF-1α and IL-8 in the tumor tissue were determined. RESULTS The EdU positive rate, OD450 value, cell invasion number, scratch healing rate, mRNA expressions of PCNA, MIEN1 and MMP-9, protein expressions of HIF-1α and IL-8, as well as the mass and volume of transplanted tumors and protein expressions of HIF-1α and IL-8 in tumor tissues were decreased by metformin in concentration/dose-dependent manner (P<0.05). Additionally,metformin increased the apoptosis rate and mRNA expression of Bim in cells (P<0.05). The trend of changes in corresponding indicators in the IDF-11774 group was consistent with that in the metformin groups, whereas DMOG could significantly attenuate the aforementioned effects of high-concentration/high-dose metformin (P<0.05). CONCLUSIONS Metformin can inhibit the proliferation, invasion, migration of TE1 cells, and tumor growth of nude mice, and induce cell apoptosis, the mechanism of which may be related to the inhibition of HIF-1α/IL-8 signaling pathway.

ObjectiveTo deeply understand the lived experience and needs of patients with end-stage heart failure, and to provide references for better implementing hospice care for patients with heart failure. MethodsA qualitative phenomenological research method was adopted to conduct in-depth interviews with 15 patients with end-stage heart failure. The Colaizzi 7-step analysis method was used to code, analyze, and extract themes from the interview data. ResultsFour themes and 10 sub-themes were identified: first, experiencing physical and psychological distress (a desire for relief from physical pain and a need for psychological counseling); second, ambivalence towards family support (yearning for care but feeling guilty); third, actively seeking social support (expecting to be understood and valued, facilitating access to support from the medical system, and differing perceptions of doctor-patient shared decision-making); fourth, complex psychological experience regarding prognosis (experiencing fear and worry, feeling disappointed, living in the moment, and accepting death). ConclusionMedical staff, family caregivers, and society should jointly pay attention to the physical and mental feelings and needs of patients with end-stage heart failure and provide targeted care. It is recommended to implement multidisciplinary team management, promote doctor-patient shared decision-making, meet individualized needs, and provide appropriate education on life and death concepts, thereby establishing a palliative and hospice care service model for end-stage heart failure with characteristics.

OBJECTIVE:
To observe the effect of heat-sensitive moxibustion at "Feishu" (BL13) on immunoinflammatory response in rats with allergic rhinitis (AR) based on phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, so as to explore its underlying mechanism.
METHODS:
Thirty-two male SD rats were randomly divided into a blank group (6 rats) and a modeling group (26 rats). In the modeling group, AR model was prepared using systemic and local attack sensitization method with ovalbumin. The successfully-modeled rats were randomized into a model group (6 rats), a medication group (6 rats) and a moxibustion group (14 rats). In the moxibustion group, the suspending moxibustion was operated at bilateral "Feishu" (BL13), 40 min each time, once daily, for 21 consecutive days; during which, the temperature of the body and tail was recorded. During intervention, if the temperature of the body and tail increased by >1 ℃, the heat-sensitive reaction at the point was determined in the rats of the moxibustion group, and these rats were collected in a heat-sensitive moxibustion group (8 rats involved and 6 rats of them were randomly collected to ensure the sample-size consistency); and those without heat-sensitive moxibustion reaction were assigned to a traditional moxibustion group (6 rats). In the medication group, fluticasone propionate nasal spray was applied, 8 μL on each side, once daily and for 21 days. The behavioral score for AR symptoms after modeling and intervention, and the content of serum immunoglobulin E (IgE) after modeling were observed. After intervention, the histological morphology of the nasal mucosa was observed using HE staining, the positive expression of thymic stromal lymphopoietin (TSLP) in the nasal mucosa was detected using immunohistochemistry, the levels of IgE, interleukin (IL)-4, IL-5, IL-13 and interferon-γ (IFN-γ) were detected by ELISA, and the protein expression of the member 4 of tumor necrosis factor receptor superfamily (OX40), phosphorylated protein kinase B (p-AKT), phosphorylated phosphatidylinositol 3-kinase (p-PI3K) in nasal mucosa was detected by Western blotting.
RESULTS:
After modeling, the behavioral score of AR symptoms and serum IgE level in the modeling group were higher than those of the blank group (P<0.01), suggesting the success of AR modeling. After intervention, compared with the blank group, the behavioral score of AR symptoms was increased (P<0.01);the nasal mucosa structure was disordered, the inflammatory infiltration was severe; the positive expression of TSLP in the nasal mucosa increased (P<0.01), the levels of serum IgE, IL-4, IL-5, and IL-13 elevated (P<0.01), and the level of IFN-γ decreased (P<0.01); and the protein expression of OX40, p-AKT, and p-PI3K in the nasal mucosa increased (P<0.05) in the model group. Compared with the model group, the behavioral score of AR symptoms was reduced (P<0.01); the nasal mucosa structure, inflammatory infiltration, and vascular dilation were ameliorated to varying degrees; the positive expression of TSLP in the nasal mucosa decreased (P<0.01); the content of serum IgE, IL-4, IL-5, and IL-13 decreased (P<0.05), and that of IFN-γ increased (P<0.05) in the medication, traditional moxibustion, and heat-sensitive moxibustion groups. Compared with the model group, the protein expression of p-AKT was reduced in the medication and traditional moxibustion groups (P<0.05), the protein expression of OX40, p-AKT, and p-PI3K in the nasal mucosa decreased in the heat-sensitive moxibustion group (P<0.05). When compared with the medication group, the positive expression of TSLP in the nasal mucosa was reduced (P<0.05) in the heat-sensitive moxibustion group. In comparison with the traditional moxibustion group, the content of serum IL-13 was reduced and the content of IFN-γ elevated in the heat-sensitive moxibustion and the medication groups (P<0.05), the protein expression of p-PI3K reduced in the medication group (P<0.05), and the positive expression of TSLP and the protein expression of OX40 and p-PI3K in the nasal mucosa were reduced in the heat-sensitive moxibustion group (P<0.05).
CONCLUSION
Heat-sensitive moxibustion at "Feishu" (BL13) can alleviate the symptoms of AR rats, ameliorate the inflammatory infiltration and telangiectasia of nasal mucosa, and inhibit immunoinflammatory response, which may be obtained by regulating PI3K/AKT signal pathway.

Based on the interleukin-17(IL-17) signaling pathway, this study explores the effect and mechanism of Bufei Decoction on Klebsiella pneumoniae pneumonia in rats. SD rats were randomly divided into the control group, model group, Bufei Decoction low-dose group(6.68 g·kg~(-1)·d~(-1)), Bufei Decoction high-dose group(13.36 g·kg~(-1)·d~(-1)), and dexamethasone group(1.04 mg·kg~(-1)·d~(-1)), with 10 rats in each group. A pneumonia model was established by tracheal drip injection of K. pneumoniae. After successful model establishment, the improvement in lung tissue damage was observed following drug administration. Core targets and signaling pathways were screened using transcriptomics techniques. Real-time fluorescence quantitative polymerase chain reaction was used to detect the mRNA expression of core targets interleukin-6(IL-6), interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and chemokine CXC ligand 6(CXCL6). Western blot was used to assess key proteins in the IL-17 signaling pathway, including interleukin-17A(IL-17A), nuclear transcription factor-κB activator 1(Act1), tumor necrosis factor receptor-associated factor 6(TRAF6), and downstream phosphorylated p38 mitogen-activated protein kinase(p-p38 MAPK), and phosphorylated nuclear factor-κB p65(p-NF-κB p65). Apoptosis of lung tissue cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling(TUNEL). The results showed that, compared with the control group, the model group exhibited significant pathological damage in lung tissue. The mRNA expression of IL-6, IL-1β, TNF-α, and CXCL6, as well as the protein levels of IL-17A, Act1, TRAF6, p-p38 MAPK/p38 MAPK, and p-NF-κB p65/NF-κB p65, were significantly increased, and the number of apoptotic cells was notably higher, indicating successful model establishment. Compared with the model group, both low-and high-dose groups of Bufei Decoction showed reduced pathological damage in lung tissue. The mRNA expression levels of IL-6, IL-1β, TNF-α, and CXCL6, and the protein levels of IL-17A, Act1, TRAF6, p-p38 MAPK/p38 MAPK, and p-NF-κB p65/NF-κB p65, were significantly decreased, with a significant reduction in apoptotic cells in the high-dose group. In conclusion, Bufei Decoction can effectively improve lung tissue damage and reduce inflammation in rats with K. pneumoniae. The mechanism may involve the regulation of the IL-17 signaling pathway and the reduction of apoptosis.
