ObjectiveTo explore the efficacy and mechanisms of Sini San in the treatment of depression and liver injury based on gut microbiota. MethodsThirty-two male Sprague-Dawley (SD) rats were randomly divided into a normal group, model group (M), Sini San group (MS, 2.5 g·kg-1), and fluoxetine group (MF, 2 mg·kg-1). Except for the normal group, rats in the other three groups were subjected to chronic unpredictable mild stress (CUMS). After 8 weeks, the open-field test and sucrose preference test were conducted. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum corticosterone (CORT), adrenocorticotropic hormone (ACTH), corticotropin-releasing factor (CRF), lipopolysaccharide (LPS), Zonulin, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), γ-aminobutyric acid (GABA) levels in the hippocampus and prefrontal cortex, and brain-derived neurotrophic factor (BDNF) levels in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect hippocampal BDNF mRNA expression. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured using the ultraviolet lactate dehydrogenase method. The ultrastructure of the intestinal epithelium was observed by electron microscopy, and gut microbiota in rat feces were analyzed using 16S rDNA high-throughput sequencing. ResultsCompared with the normal group, the sucrose preference of rats in the model group was significantly reduced (P<0.01), whereas it was significantly increased in the Sini San group compared with the model group (P<0.05). Compared with the normal group, hippocampal GABA protein levels and BDNF mRNA expression in the model group were significantly decreased (P<0.05), and compared with the model group, both were significantly increased in the Sini San group (P<0.05, P<0.01). Compared with the normal group, serum LPS and Zonulin levels in the model group were significantly increased (P<0.05, P<0.01), and compared with the model group, Zonulin levels in the Sini San group were significantly decreased (P<0.05). No obvious changes were observed in the ultrastructure of the jejunal mucosa among groups. Compared with the normal group, widened and blurred tight junctions, sparse and shortened microvilli, and mitochondrial swelling with cristae disruption in epithelial cells were observed in the ileal and colonic mucosa of the model group, which were markedly improved in the Sini San and fluoxetine groups. The results of 16S rDNA high-throughput sequencing showed that Sini San improved CUMS-induced dysbiosis of Bacteroidetes and Proteobacteria. Correlation analysis indicated that Bacteroidetes and Proteobacteria were significantly correlated with depression-related indicators, liver function, and intestinal mucosal permeability. ConclusionSini San exerts antidepressant and hepatoprotective effects by improving Bacteroidetes and Proteobacteria and inhibiting the increase in intestinal mucosal permeability in CUMS rats.

ObjectiveTo investigate the effects of the classical Chinese medicine compound prescription Erjingwan on the inflammatory response and apoptosis of skeletal muscle cells in a mouse model of sarcopenia and decipher the mechanism based on the silent information regulator 1 (SIRT1)/nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway. MethodsForty C57/BL6 male mice were randomized into a control group, a model group, and groups with different doses of Erjingwan (8,16,32 g·kg-1). The mouse model of sarcopenia was established by D-gal-induced skeletal muscle senescence. The body weight and grip strength of mice treated with different doses of Erjingwan were examined to evaluate their physiological functions. Hematoxylin-eosin (HE) staining and Masson staining were used to observe the pathological changes and fibrosis in the skeletal muscle of mice. Enzyme-linked immunosorbent assay (ELISA) was adopted to determine the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the serum samples of mice, and biochemical tests were conducted to quantify the levels of superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione (GSH) in the serum. The protein and mRNA levels of SIRT1, Nrf2, B-cell lymphoma (Bcl-2), and Bcl-2-associated X protein (Bax) were determined by Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), respectively. ResultsAfter 4 weeks of drug intervention, the model group exhibited significant reductions in body weight and grip strength (P0.01) compared with the control group. Compared with the model group, all doses of Erjingwan increased the body weight in mice at week 8 (P0.01) and grip strength from week 6 (P0.01). HE staining revealed clear muscle fiber structure in the control group, muscle fiber rupture and atrophy in the model group, and dose-dependent repair of muscle fiber structure in the Erjingwan groups. Masson staining showed minimal collagen fibers and mild fibrosis in the control group, collagen fiber proliferation and severe fibrosis in the model group, and collagen proliferation with dose-dependent inhibition of fibrosis in the Erjingwan groups. ELISA results showed that serum levels of TNF-α and IL-6 were elevated in the model group compared with those in the control group (P0.01). After intervention, the low-dose Erjingwan group exhibited a decreased TNF-α level (P0.05), while the medium and high-dose groups showed decreases in both TNF-α and IL-6 levels (P0.01). Biochemical assays revealed that the model group had decreased SOD and GSH levels (P0.01) and an increased MDA level (P0.01) compared with the control group. The medium and high-dose Erjingwan groups exhibited increases in SOD and GSH levels (P0.01) and decreases in MDA level (P0.01), compared with the model group. WB and Real-time PCR results showed that compared with the control group, the model group presented down-regulated protein and mRNA levels of SIRT1, Nrf2, HO-1, and Bcl-2 in the muscle tissue (P0.01) and up-regulated protein and mRNA levels of Bax (P0.01). Compared with the model group, Erjingwan at different doses up-regulated the protein levels of SIRT1, Nrf2, HO-1, and Bcl-2 (P0.01) and down-regulated the protein and mRNA levels of Bax (P0.01) in the muscle tissue. Low-dose Erjingwan elevated the mRNA levels of Nrf2 and HO-1 (P0.05, P0.01), and medium and high-dose Erjingwan up-regulated the mRNA levels of SIRT1, Nrf2, HO-1, and Bcl-2 (P0.01). ConclusionErjingwan reduced the content of inflammatory factors in skeletal muscle cells, improved the antioxidant capacity, and attenuated pathological changes and fibrosis in the muscle of the mouse model of sarcopenia by regulating the SIRT1/Nrf2/HO-1 pathway, inflammatory response, and apoptosis network.

OBJECTIVE To investigate the effects and potential mechanism of curcumin on neurological injury in neonatal rats with bacterial meningitis based on the signal transducer and activator of transcription 1( STAT1)/ nucleotide-binding domain leucine- rich repeat and pyrin domain-containing receptor 3 (NLRP3) signaling pathway. METHODS Neonatal rats, with an equal number of males and females, were randomly divided into control group, model group, curcumin low-dose (Cur-L), medium-dose (Cur- M) and high-dose (Cur-H) groups, and Cur-H+STAT1 transcription enhancer [2-(1,8-naphthyridin-2-yl)phenol] group (Cur-H+2- NP group), with 15 rats in each group. Except for the control group, rats in other groups were injected with a suspension of group B Streptococcus (1×104 cfu/mL, 10 μL) into the cerebellomedullary cistern to establish a bacterial meningitis model. After successful model establishment, rats in Cur-L, Cur-M and Cur-H groups were intraperitoneally injected with 1.25, 2.5 and 5 mg/kg curcumin, respectively, and those in the Cur-H+2-NP group were intraperitoneally injected with 5 mg/kg curcumin and 0.5 mg/kg 2- NP, once a day, for 3 consecutive weeks. After the last administration, modified Loeffler score was conducted, white blood cells (WBC) count in cerebrospinal fluid as well as the contents of inflammatory factors [tumor necrosis factor-α, interleukin-6 (IL-6), IL-1β and IL-18], brain water content and blood-brain barrier permeability were detected; the histopathological changes of hippocampus and cortex tissues were observed. The percentage of apoptosis in hippocampal/cortical tissue cells, the positive expression of ionized calcium-binding adapter molecule-1 (Iba-1), the co-localization of Iba-1 and NLRP3, as well as the expressions of proteins related to the STAT1/NLRP3 signaling pathway (phosphorylated STAT1, NLRP3, apoptosis-associated speck-like protein containing a CARD, gasdermin D, caspase-1, IL-1β and IL-18) were examined. RESULTS Compared with the control group, the neurons in the hippocampal/cortical tissues of rats in the model group exhibited significant morphological abnormalities, accompanied by neuronal edema and necrosis, as well as infiltration of inflammatory cells. The modified Loeffler score and the number of Nissl bodies were significantly decreased/reduced in the model group, while the WBC count, levels of inflammatory factors, brain water content, blood-brain barrier permeability, HE staining score, number of degenerated neurons, percentage of apoptotic cells, positive expression of Iba-1, percentage of Iba-1 and NLRP3 co-localization- positive cells, and expressions of pathway-related proteins were all significantly rose/increased/upregulated (P<0.05). Compared with the model group, the histopathological changes in the hippocampal/cortical tissues of rats in all curcumin dosage groups were alleviated to varying degrees, with significant improvements in all quantitative indicators (P<0.05); conversely, 2-NP significantly reversed the ameliorative effects of curcumin on these quantitative indicators (P<0.05). CONCLUSIONS Curcumin can alleviate cerebral edema and blood-brain barrier damage, reduce neuroinflammation, inhibit cell apoptosis and pyroptosis, and thereby alleviate neuronal injury in neonatal rats with bacterial meningitis. The underlying mechanism may be related to the inhibition of the STAT1/NLRP3 signaling pathway.

Breast cancer (BC), a common malignant tumor in women, is characterized by high incidence and mortality rates, posing a serious threat to women's life and health. Currently, the commonly used treatments for BC include surgery, radiotherapy, chemotherapy, molecular targeted therapy, and endocrine therapy. Although radiotherapy and chemotherapy can effectively kill tumor cells and inhibit the proliferation and differentiation of tumor cells, they can induce adverse reactions such as hematopoietic dysfunction and impaired immune function. The other treatment methods also have problems such as drug resistance, high recurrence rates, reduced quality of life, and poor clinical efficacy. Therefore, it is urgent to explore new drugs with better efficacy and lower toxicity. Ferroptosis is a form of iron-dependent, non-apoptotic programmed cell death triggered by lipid peroxidation. In recent years, ferroptosis has become a hot topic in the field of cancer treatment and has been gradually proven to effectively inhibit the proliferation and metastasis of BC cells, reduce the drug resistance of BC to chemotherapy drugs, and enhance the sensitivity of BC to radiotherapy. Traditional Chinese medicine (TCM), with multiple components, multiple targets, and mild side effects, is widely used in the treatment of BC. A large number of studies have shown that active ingredients of TCM, such as saponins, flavonoids, terpenoids, phenols, and polysaccharides, can inhibit the proliferation and metastasis of BC cells by modulating ferroptosis-related pathways. These include iron metabolism, lipid metabolism, cystine/glutamate antiporter system Xc-/glutathione/glutathione peroxidase 4, Specifically, these ingredients elevate the levels of lipid peroxidation, reactive oxygen species, malondialdehyde, and Fe2+ in BC cells, thereby inducing ferroptosis-mediated suppression of tumor progression. This article reviews the relevant literature at home and abroad in recent years, summarizes the mechanisms of ferroptosis in regulating BC and the research progress in the active components of TCM targeting ferroptosis in the intervention of BC, aiming to provide ideas for the development of new drugs for the treatment of BC.

To investigate the changes in peripheral blood immune cells before and after the onset of septic shock in patients with malignant tumors, and to analyze the relationship between these immune cells and patient prognosis. A retrospective study was conducted, enrolling perioperative tumor patients who were transferred to the intensive care unit (ICU) due to septic shock at Shanxi Provincial Cancer Hospital between October 2018 and December 2019.Changes in lymphocyte counts and subsets were compared before and after septic shock (measured prior to septic shock onset and within 72 hours after onset).A multivariate Logistic regression model was used to analyze the relationship between these immune indicators and the 28-day mortality risk in tumor patients following septic shock. A total of 47 tumor patients transferred to the ICU due to septic shock were included.There were 32 males and 15 females, with a mean age of (63.9±11.2) years.Gastrointestinal tumors were the most common tumor type (76.60%, 36/47), and abdominal/pelvic infection (65.96%, 31/47) was the primary source of infection.Within 28 days after ICU transfer, 12 patients died and 35 survived. Compared to pre-septic shock levels, lymphocyte counts significantly decreased after septic shock[530(300, 830) cells/μL Perioperative tumor patients experience acute depletion of peripheral blood lymphocyte subsets following septic shock.Among various immune indicators, regulatory T cell count serves as an independent predictor of short-term mortality risk.Evaluating baseline immune function in such patients may help optimize treatment strategies and improve overall prognosis.

To develop and validate a model for predicting intensive care unit (ICU) mortality risk in patients with malignant tumors complicated by acute respiratory failure (ARF) based on an explainable machine learning framework. Clinical data of patients with malignant tumors and ARF were extracted from the eICU Collaborative Research Database in the United States, including demographic characteristics, comorbidities, vital signs, laboratory test indicators, and major interventions within the first 24 hours after ICU admission.The study outcome was ICU death.Enrolled patients were randomly divided into a training set and a validation set at a ratio of 7:3.Predictor variables were selected using least absolute shrinkage and selection operator (LASSO) regression.Five machine learning algorithms-extreme gradient boosting (XGBoost), support vector machine (SVM), Logistic regression, multilayer perceptron (MLP), and C5.0 Decision Tree-were employed to construct predictive models.Model performance was evaluated based on the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, and other metrics.The optimal model was further interpreted using the Shapley additive explanations (SHAP) algorithm. A total of 3196 patients with malignant tumors complicated by ARF were included.The training set comprised 2, 261 patients and the validation set 935 patients; 683 patients died during ICU stay, while 2513 survived.LASSO regression ultimately selected 12 variables closely associated with patient ICU outcomes, including sepsis comorbidity, use of vasoactive drugs, and within the first 24 hours after ICU admission: minimum mean arterial pressure, maximum heart rate, maximum respiratory rate, minimum oxygen saturation, minimum serum bicarbonate, minimum blood urea nitrogen, maximum white blood cell count, maximum mean corpuscular volume, maximum serum potassium, and maximum blood glucose.After model evaluation, the XGBoost model demonstrated the best performance.The AUCs for predicting ICU mortality risk in the training and validation sets were 0.940 and 0.763, respectively; accuracy was 88.3% and 81.2%;sensitivity was 98.5% and 95.9%.Its predictive performance also remained optimal in sensitivity analyses.SHAP analysis indicated that the top five variables contributing to the model's predictions were minimum oxygen saturation, minimum serum bicarbonate, minimum mean arterial pressure, use of vasoactive drugs, and maximum white blood cell count. This study successfully developed a mortality risk prediction model for ICU patients with malignant tumors complicated by ARF based on a large-scale dataset and performed explainability analysis.The model aids clinicians in early identification of high-risk patients and implementing individualized interventions.

This paper summarizes Professor DING Ying's clinical experience in the treatment of systemic lupus erythematosus (SLE) through differentiation of three states, yin fire, latent fire, and fire toxin. It is proposed that fire pathogenic factors constitute a key pathological element running throughout the entire disease course of SLE. The evolution of its pathogenesis centers on these three states, spleen-kidney deficiency with the initial emergence of yin fire as the onset of disease, damage to yin by medicinal toxicity with internal blazing of latent fire as the driver of disease progression, and the interlocking of blood stasis and heat with intense scorching by fire toxin as the critical factor leading to severe and life-threatening conditions. Corresponding to these three stages, targeted prescriptions are formulated, Jiuwei Yishen Formulation (九味益肾方) to tonify the spleen and kidney, raise yang, and disperse fire; Ziyin Xiehuo Decoction (滋阴泄火汤) to nourish yin and fluids while clearing latent fire; and Santeng Changluo Jiedu Decoction (三藤畅络解毒汤) to dispel blood stasis, unblock the collaterals, detoxify, and restrain fire. This staged and integrated therapeutic strategy aims to address both root and branch and to achieve overall regulation, providing valuable guidance for the clinical differentiation and treatment of SLE.

Objective To study the five-year survival status and influencing factors of elderly patients with lung cancer complicated with chronic obstructive pulmonary disease (COPD). Methods A cohort study was conducted to follow up 450 patients with lung cancer and chronic obstructive pulmonary disease who were hospitalized in our hospital from January 2018 to December 2023. The endpoint of the follow-up was the end of a five-year period or death. The Life Tables method was used to calculate survival rates and plot survival curves. The Cox proportional hazards model was used to analyze the influencing factors of five-year survival. Results The results indicated that the overall five-year survival rate of patients was 4.89%, and it decreased year by year. Cox regression analysis showed that age, gender, family functioning, and psychological status significantly influenced patient survival rate (all P<0.05). Stratified analysis found that the smoking status, family functioning, and psychological status of male patients all had an impact on survival rate (all P<0.05), while the psychological status of female patients had a more significant impact on survival (P=0.008). Conclusion This study provides a scientific basis for comprehensive intervention of elderly lung cancer patients with COPD. It is recommended that clinical attention should be paid to psychological and family factors to improve patient prognosis.

Objective To understand the status of body image disturbance and its influencing factors in patients with ankylosing spondylitis (AS), so as to provide a scientific basis for the clinical management of AS. Methods A total of 353 AS patients admitted from January 2022 to December 2024 were selected as research subjects. Chinese version of Body Image Disturbance Questionnaire (BIDQ) was used to investigate the body image disturbance in AS patients. Single factor analysis was performed by t test and analysis of variance, and multiple factors were analyzed by multivariate linear regression. Results The total score of BIDQ in 342 AS patients was (25.01±4.22). Multivariate linear regression analysis results showed that self-paid medical expense, nighttime VAS score and negative emotion PANAS score could positively predict body image disturbance in AS patients (standardized regression coefficient=0.413, 0.413, 0.460, P<0.05), and PSSS score, positive emotion PANAS score and exercise management CDSSM score could negatively predict body image disturbance (standardized regression coefficient=-0.245, -0.134, -0.247, P<0.05). Conclusion The body image disturbance in AS patients is worthy of clinical attention. Nighttime pain, negative emotion and self-paid medical treatment can increase the risk of body image disturbance. Positive emotion, social support and high self-management level of exercise behavior can reduce the formation of body image disturbance, which can provide new ideas for clinical management of AS patients.
