Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is the primary cause of mortality in sepsis, with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response. Due to the systemically convergent yet clinically heterogeneous nature of the host response, current understanding and management strategies for hemodynamics remain inconsistent, often leading to inadequate resuscitation or overtreatment. To improve the quality of care, based on a systematic review of the "blood flow-oxygen flow" theory, an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow, and has formulated the

As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

ObjectiveTo elucidate the efficacy connotation of Shudi Qiangjin pills (SQP) against liver and kidney deficiency in steroid-induced osteonecrosis of femoral head (SONFH) from the perspective of the "disease-syndrome-formula" association and to clarify the underlying mechanisms based on in vivo and in vitro experiment validation. MethodsThe chemical components and the corresponding putative targets of SQP were collected from the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0, the Encyclopedia of Traditional Chinese Medicine (ETCM) v2.0, and HERB databases. The SONFH-related genes were identified based on the differential expression profiles of peripheral blood of patients with SONFH compared to the healthy volunteers, and the disease phenotype-related targets were collected from the TCMIP v2.0 database. Then, the interaction network of "SONFH-related genes and candidate targets of SQP" was constructed based on "gene-gene interaction information", and the major network targets were screened by calculating the topological characteristic values of the network followed by the functional mining according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and the SoFDA database. After that, the SONFH rat model was prepared by lipopolysaccharide combined with methylprednisolone injection, and 2.5, 5, 7.5 g·kg-1 SQP (once per day, equivalent to 1, 2, and 3 times the clinical equivalent dose, respectively) or 7.3×10-3 g·kg-1 of alendronate sodium (ALS, once per week, equivalent to the clinical equivalent dose) was given for 8 weeks. The effect characteristics of SQP and ALS in the treatment of SONFH were evaluated by micro-computed tomography scanning, hematoxylin and eosin staining, alkaline phosphatase (ALP) staining, immunohistochemical staining, enzyme-linked immunosorbent assay, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)staining, and a comparative efficacy analysis was conducted with ALS. In addition, SONFH cell models were prepared by dexamethasone stimulation of osteoblasts, and the intervention was carried out with the medicated serum of SQP at the aforementioned three doses. Cell counting kit-8, ALP staining, ALP activity assay, alizarin red staining, and flow cytometry were employed to investigate the regulatory effect of SQP on osteoblasts. The expression levels of osteogenesis-related proteins and key factors of the target signaling axis were detected by quantitative real-time polymerase chain reaction and Western blot. ResultsThe network analysis results demonstrated that the candidate targets of SQP primarily exerted their therapeutic effects through key signaling pathways, including phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt), lipid metabolism and atherosclerosis, prolactin, chemokines, and neurotrophic factors pathways. These pathways were significantly involved in critical biological processes such as muscle and bone metabolism and the regulation of the "neuro-endocrine-immune" network, thereby addressing both modern medical symptoms (e.g., delayed skeletal maturation and recurrent fractures) and traditional Chinese medicine (TCM) symptoms (e.g., fatigue, aversion to cold, cold limbs, and pain in the limbs and joints in patients with SONFH characterized by liver and kidney deficiency syndrome. Among these pathways, the PI3K/Akt signaling pathway exhibited the highest degree of enrichment. The in vivo experimental results demonstrated that starting from the 4th week after modeling, the modeling group exhibited a significant reduction in body weight compared to the control group (P<0.05). After six weeks of treatment, all dosage groups of SQP showed significantly higher body weights compared to the model group (P<0.01). Compared with the normal group, the model group exhibited significant decreases in bone mineral density (BMD), bone volume fraction (BV/TV), trabecular number (Tb.N), osteocalcin (OCN), alkaline phosphatase (ALP) levels in femoral head tissue, and serum bone-specific alkaline phosphatase (BALP) (P<0.01), along with significant increases in trabecular separation (Tb.Sp), empty lacunae rate in tissue, and apoptosis rate (P<0.01). In comparison to the model group, the SQP intervention groups showed significant improvements in BMD, BV/TV and Tb.N (P<0.01), significant reductions in Tb.Sp, empty lacunae rate and apoptosis rate (P<0.05), and significant increases in protein levels of OCN and ALP as well as BALP content (P<0.05). The in vitro experimental results revealed that all dosage groups of SQP medicated serum showed no toxic effects on osteoblast. Compared with the normal group, the model group displayed significant suppression of osteoblast proliferation activity, ALP activity, and calcified nodule formation rate (P<0.01), significant decreases in mRNA transcription levels of OCN and Runt-related transcription factor 2 (RUNX2) (P<0.01), significant reductions in protein content of osteopontin (OPN), typeⅠ collagen (ColⅠ)A1, B-cell lymphoma-2 (Bcl-2), PI3K, and phosphorylated (p)-Akt (P<0.01), and a significant increase in apoptosis rate (P<0.01). Compared with the model group, the SQP medicated serum intervention groups exhibited significant increases in proliferation activity, ALP activity, calcified nodule formation rate, mRNA transcription levels of OCN and RUNX2, and protein content of OPN, ColⅠA1, Bcl-2, PI3K, and p-Akt (P<0.05), along with a significant decrease in apoptosis rate (P<0.01). ConclusionSQP can effectively reduce the disease severity of SONFH with liver and kidney deficiency syndrome and improve bone microstructure, with the therapeutic effects exhibiting a dose-dependent manner. The mechanism may be related to its regulation of key processes such as muscle and bone metabolism and the correction of imbalances in the "neuro-endocrine-immune" network, thereby promoting osteoblast differentiation and inhibiting osteoblast apoptosis. The PI3K/Akt signaling axis is likely one of the key pathways through which this formula exerts its effects.

The homeostasis of the oral microbiome is essential for maintaining host health, and its disruption can contribute to the development of both oral and systemic diseases. The oral microbiome influences the initiation and progression of oral squamous cell carcinoma (OSCC) through multiple mechanisms. ① Oral microbes can directly act on epithelial cells, inducing cell-cycle dysregulation, DNA damage, and epigenetic reprogramming, thereby promoting cell proliferation and epithelial-mesenchymal transition (EMT). For example, Fusobacterium nucleatum binds to E-cadherin via its adhesin FadA, activating the β-catenin pathway and directly driving tumor-cell proliferation and EMT, while Porphyromonas gingivalis reprograms lipid synthesis to enhance the stemness of OSCC cells. ② Oral microbes and their metabolites reshape the tumor immune-suppressive microenvironment by altering the density, composition, and function of infiltrating immune cells. Periodontal pathogens induce a chronic inflammatory state in the oral cavity and activate signaling cascades such as MAPK/ERK and NF-κB, thereby indirectly accelerating OSCC progression. ③ Bacteria and viruses in the oral cavity exhibit synergistic interactions. Bacterial biofilms and proteases facilitate viral activation and infection, and microbial metabolites such as butyrate can enhance histone acetylation to promote the lytic reactivation of latent viruses. ④ At the ecological level, the depletion of commensals and expansion of anaerobic pathogens disrupt the metabolic network of the community, and complex interspecies interactions collectively shape a pro-carcinogenic niche that drives OSCC progression on multiple fronts. Future studies should integrate multi-omics analyses with longitudinal clinical cohorts to explore functional causal networks of key microbial communities and develop individualized targeted intervention strategies for microecology.

A 42-year-old male with chest tightness and dyspnea was admitted to the hospital. Chest CT indicated diffuse interstitial lung infiltration. Despite receiving anti-infective therapy, glucocorticoid therapy, and immunosuppressive agents, the patient developed refractory hypoxaemia. Endotracheal intubation and invasive mechanical ventilation failed to improve oxygenation. Therefore the patient was diagnosed with rapidly progressive interstitial lung disease (RP-ILD) accompanied by type Ⅰ respiratory failure. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated, and oxygenation improved in this patient. The patient subsequently underwent bilateral lung transplantation with veno-arterio-venous (VAV) ECMO support. ECMO machine was withdrawn on day 1, and extubation was achieved on day 9 after surgery. Histopathology revealed fibrotic nonspecific interstitial pneumonia (NSIP) with hyaline membrane formation. The patient developed ICU-acquired myasthenia and received early rehabilitation, with gradual recovery of muscle strength. During follow-up, graft lung function remained stable. This case demonstrates that ECMO can serve as a bridge to lung transplantation in RP-ILD patients.

ObjectiveTo investigate the mechanism by which Shaoyaotang regulates the miRNA-155-mediated suppressor of cytokine signaling 1 (SOCS1)/Janus kinase 1 (JAK1)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and thereby affects macrophage polarization. MethodsThe cell-counting kit-8 (CCK-8) assay was used to detect the effect of drug-containing serum of Shaoyaotang at different concentrations on the viability of RAW 264.7 cells. A cell model of inflammation was established by stimulating RAW264.7 cells with lipopolysaccharide (LPS) at a concentration of 10 mg·L-1 The modeled cells were assigned by the random number table method into seven groups: LPS-induced M1 polarization (model), M1+miRNA-155 mimics, M1+miRNA-155 inhibitor, M1+Shaoyaotang-containing serum, M1+miRNA-155 mimics+Shaoyaotang-containing serum, M1+miRNA-155 inhibitor+Shaoyaotang-containing serum, and M1+blank serum. Enzyme-linked immunosorbent assay was employed to measure the levels of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β)]. Immunofluorescence assay was used to detect the expression of macrophage polarization markers [inducible nitric oxide synthase (iNOS) and macrophage mannose receptor 1 (CD206)]. Real-time PCR was employed to measure the expression of miRNA-155 in cells. Western blot was performed to determine the protein levels of SOCS1, STAT1, and JAK1. ResultsCompared with the LPS-induced M1 polarization (model) group, the M1+miRNA-155 mimics group showed up-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and down-regulated expression of CD206 (P<0.05). In both the M1+miRNA-155 inhibitor group and the M1+Shaoyaotang-containing serum group, the expression levels of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS were down-regulated (P<0.05), while those of SOCS1 and CD206 were up-regulated (P<0.05). Compared with the M1+miRNA-155 mimics group, the M1+miRNA-155 mimics+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). Compared with the M1+miRNA-155 inhibitor group, the M1+miRNA-155 inhibitor+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). ConclusionShaoyaotang regulates macrophage polarization by modulating miRNA-155 expression and interfering with the SOCS1/JAK1/STAT1 signaling pathway. The findings provide new experimental evidence for the treatment of ulcerative colitis with Shaoyaotang.

ObjectiveTo investigate the potential role and underlying mechanisms of Shaoyaotang in intervening macrophage glycolytic reprogramming in ulcerative colitis (UC). MethodsForty-eight C57BL/6 mice were randomly divided into six groups: Normal control group, model group, mesalazine group (0.39 g·kg-1), Shaoyaotang group (15.54 g·kg-1), 2-deoxy-D-glucose (2-DG) group (glycolysis inhibitor, 100 mg·kg-1), and 2-DG + Shaoyaotang combined group (100 mg·kg-1+15.54 g·kg-1). Except for the normal control group, mice in the other five groups were induced to establish UC models using dextran sulfate sodium (DSS). The normal control group was administered pure water via intragastric gavage, while the other groups received intragastric gavage of mesalazine solution, intragastric gavage of Shaoyaotang, and the 2-DG group was treated with 2-DG via intraperitoneal injection. After 7 consecutive days of treatment, colonic tissues were extracted. Hematoxylin and eosin (HE) staining was performed to evaluate histopathological changes and tissue injury in the colon. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in colonic tissues. Western blot analysis was employed to determine the expression levels of hypoxia-inducible factor-1α (HIF-1α), glucose transporter (GLUT1), lactate dehydrogenase A (LDHA), pyruvate kinase M2 (PKM2), and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) in colonic tissues. Immunofluorescence was conducted to detect the expression of CD206 and inducible nitric oxide synthase (iNOS) in colonic tissues. Liquid chromatography-mass spectrometry (LC-MS) was utilized to measure lactate and citrate levels in colonic tissues. ResultsCompared with the normal control group, mice in the model group exhibited a significant increase in disease activity index (DAI) scores, accompanied by colonic mucosal congestion, edema, and inflammatory cell infiltration, significantly elevated expression of the inflammatory cytokine TNF-α (P<0.05), significantly decreased IL-10 expression (P<0.05), significantly increased levels of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 in colonic tissues (P<0.05), markedly elevated iNOS expression (P<0.05), significantly decreased CD206 expression (P<0.05), and significantly elevated lactate and citrate levels in colonic tissues (P<0.05). In contrast to the model group, the Shaoyaotang group, inhibitor group, and Shaoyaotang combined with inhibitor group demonstrated amelioration of mucosal injury in colonic tissues, markely decreased expression levels of the inflammatory cytokine TNF-α (P<0.05), elevated IL-10 expression levels, significantly decreased expression of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 (P<0.05), markedly reduced iNOS expression levels (P<0.05), significantly increased CD206 expression (P<0.05) and significantly decreased lactate and citrate levels (P<0.05). ConclusionShaoyaotang ameliorates symptoms of DSS-induced UC in mice, and its therapeutic mechanism may be associated with regulating macrophage glycolytic reprogramming via modulation of the HIF-1α signaling pathway.

ObjectiveTo investigate the role of microRNA-155-5p (miR-155-5p) in ulcerative colitis (UC) and study the molecular mechanism of Shaoyaotang in the treatment of UC by regulating miR-155-5p. MethodsForty-eight SPF-grade male C57BL/6 mice were selected and assigned via the random number table method into 6 groups (n=8): A blank control group, a model group, a mesalazine (0.39 g·kg-1) group, a Shaoyaotang (31.08 g·kg-1) group, a Janus kinase 1 (JAK1) inhibitor (baricitinib, 10 mg·kg-1) group, and a Shaoyaotang combined with inhibitor (baricitinib 10 mg·kg-1 + Shaoyaotang 31.08 g·kg-1) group. After successful modeling of UC by gavage of 3% dextran sulphate sodium solution, each group received corresponding drug intervention for 7 days. Shaoyaotang and mesalazine were administered by gavage, and baricitinib by intraperitoneal injection. Twenty-four hours after the last administration, mice were anesthetized by intraperitoneal injection of pentobarbital sodium, and blood was collected for determination of white blood cell count and erythrocyte sedimentation rate (ESR). Mice were then sacrificed for measurement of colon length. Hematoxylin-eosin staining was used to observe colonic pathological changes and perform pathological scoring. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the relative expression of miR-155-5p in the colonic tissue, and Western blot was used to determine the protein levels of JAK1, phosphorylated JAK1 (p-JAK1), suppressor of cytokine signaling 1 (SOCS1), signal transducer and activator of transcription 1 (STAT1), and phosphorylated STAT1 (p-STAT1). ResultsCompared with the blank control group, the model group showed increased disease activity index (DAI) score and pathological score, shortened colon, upregulated relative expression of miR-155-5p and protein levels of p-JAK1 and p-STAT1, downregulated protein level of SOCS1 in the colonic tissue, prolonged time of erythrocyte sedimentation, and increased white blood cell count (P<0.01). Compared with the model group, all drug-treated groups exhibited improvements in the above indicators (P<0.01). Moreover, the Shaoyaotang group showed better therapeutic effects than the mesalazine group in regulating miR-155-5p expression, related protein levels, DAI score, and colonic pathological score (P<0.01). ConclusionShaoyaotang may downregulate miR-155-5p to relieve its inhibition on SOCS1, thereby suppressing the excessive activation of the JAK1/STAT1 signaling pathway and ultimately alleviating intestinal inflammatory damage.

ObjectiveTo investigate the role of the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway in intestinal mucosal barrier damage in ulcerative colitis, as well as the intervention mechanism of Shaoyaotang. MethodsSixty SD rats were allocated into a blank group, a model group, a mesalazine (0.42 g·kg-1) group, and low-, medium-, and high-dose (11.1, 22.2, 44.4 g·kg-1, respectively) Shaoyaotang groups. A model of ulcerative colitis was induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS). After successful modeling, rats were administrated with corresponding agents via gavage for 7 days. Changes in colon length and colon weight were observed. Hematoxylin-eosin staining was performed to examine the pathological changes of the colon, and immunohistochemistry was employed to detect the expression of the inflammatory cytokine interleukin-8 (IL-8), cyclooxygenase-2 (COX-2), junction adhesion molecule-1 (JAM-1), and claudin-1 in the colon. Western blot analysis was performed to determine the protein levels of TLR4, MyD88, and NF-κB in the colon. ResultsCompared with the blank group, the model group showed elevated DAI score (P<0.01), reduced colon length and colon weight (P<0.01), down-regulated protein levels of JAM-1 and claudin-1 (P<0.01), and up-regulated protein levels of IL-8, COX-2, TLR4, MyD88, and NF-κB p65 (P<0.01) in the colon tissue. Compared with the model group, each treatment group showed decreased DAI score (P<0.05, P<0.01), increased colon length and colon weight (P<0.05, P<0.01), up-regulated protein levels of JAM-1 and claudin-1 (P<0.01), and down-regulated protein levels of IL-8, COX-2, TLR4, MyD88, and NF-κB p65 (P<0.01) in the colon tissue. ConclusionShaoyaotang alleviates intestinal inflammation and intestinal mucosal damage to protect intestinal barrier integrity by regulating the TLR4/MyD88/NF-κB signaling pathway.
