OBJECTIVE To prepare an intelligent responsive liposome-hydrogel nanopreparation co-loaded with gambogic acid (GA), and characterize its antitumor activity in vitro . METHODS GA-ICG-Lip-gel was prepared by ethanol injection and cold dissolution, incorporating GA and the photosensitizer indocyanine green (ICG). The appearance and microscopic morphology of GA-ICG-Lip-gel were observed, its encapsulation efficiency and drug loading capacity were measured, and its photothermal conversion performance, photothermal stability, and infrared imaging properties were investigated, along with the determination of its in vitro release profile. Human breast cancer MCF-7 cells were used as objects to investigate the effects of GA-ICG-Lip-gel (or with near-infrared light irradiation) on cell viability, migration ability, and the cellular uptake capacity of GA-ICG-Lip-gel. RESULTS GA-ICG-Lip-gel existed in a solution state at room temperature and transformed into a gel state at 37 ℃. Its microstructure was dense with small pores, and its encapsulation efficiency and drug loading were (96.07±0.86) % and (6.28±1.16) %, respectively. After exposure to near-infrared light, the temperature of GA-ICG-Lip-gel rose above 42 ℃, with no significant attenuation observed in the heating curve. The heating efficiency was dependent on both the irradiation time and drug concentration. Compared to media without gelatinase, the cumulative release rate of GA-ICG-Lip-gel increased in media containing gelatinase. In vitro studies showed that GA-ICG-Lip-gel could be efficiently taken up by MCF-7 cells; GA-ICG-Lip-gel significantly inhibited the viability and migration ability of MCF-7 cells ( P <0.05), and this inhibitory effect was further enhanced under near-infrared light irradiation. CONCLUSIONS This study successfully prepares GA-ICG-Lip-gel, which exhibits favorable photothermal conversion properties and temperature/enzyme dual-responsive drug release characteristics, and demonstrates significant inhibitory effects on the proliferation and migration of breast cancer cells.

Objective:
To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents.
Methods:
A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models.
Results:
The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05).
Conclusions
Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

ObjectiveTo investigate the association of hepatic steatosis with the level of viral replication and the progression of hepatic fibrosis in patients with chronic hepatitis B (CHB) through a real-world study, and to determine the independent influencing factors for hepatic fibrosis. MethodsA total of 887 CHB patients who attended the outpatient service and inpatient ward of Hepatology in The First Affiliated Hospital of Dalian Medical University from July 2021 to March 2025 were enrolled as subjects, and according to the presence or absence of metabolic dysfunction-associated steatotic liver disease (MASLD), they were divided into CHB group with 560 patients and CHB+MASLD group with 327 patients. The association between hepatic steatosis and HBV load in CHB patients was analyzed, as well as the impact of varying degrees of hepatic steatosis on hepatic fibrosis. The t-test or the Mann-Whitney U test was used for comparison of continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups; a Spearman correlation analysis was performed; a Logistic regression analysis was used to investigate influencing factors. ResultsThe patients enrolled received antiviral therapy according to viral load; of all patients, 275 (31%) received nucleos(t)ide analogue combined with pegylated interferon-α, 532 (60%) received nucleos(t)ide analogue monotherapy, and 80 (9%) did not receive antiviral therapy. A total of 44 patients (5.0%) who were receiving PEG-IFN-α therapy and had marked thrombocytopenia were excluded, and finally 843 patients were included for comparison of aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 index (FIB-4). Compared with the CHB group, the CHB+MASLD group had a significantly higher proportion of male patients (χ2=5.917, P<0.05) and a significant increase in CAP value (t=21.646, P<0.05). The median values of liver function parameters for the population enrolled were within the normal range, and no significant inflammatory activity was observed. The virological analysis showed that compared with the CHB group, the CHB+MASLD group had significantly lower serum level of pregenomic RNA (Z=-2.894, P<0.05) and HBeAg positivity rate (χ2=8.725, P<0.05), and CAP was significantly negatively correlated with pgRNA (r=-0.117, P<0.05). In the HBeAg-negative subgroup, compared with the CHB group, the CHB+MASLD group had a significantly lower level of hepatitis B surface antigen (Z=-0.765, P<0.05); in the HBeAg-positive subgroup, the CHB+MASLD group had a significantly higher level of HBV DNA than the CHB group (Z=-2.509, P<0.05). The analysis of hepatic fibrosis showed that the CHB+MASLD group had significantly lower values of APRI (Z=-3.418, P<0.05) and FIB-4 (Z=-6.237, P<0.05). Compared with the CHB group, the CHB+MASLD S1 group had a significantly higher proportion of patients without fibrosis and a significantly lower proportion patients with liver cirrhosis (χ2=7.935, P<0.05); in the CHB+MASLD S2 group, there was no significant difference in the proportion of patients with different fibrosis stages; the CHB+MASLD S3 group had a significantly lower proportion of patients without fibrosis and a significantly higher proportion of patients with early-stage fibrosis (χ2=9.101, P<0.05). The Logistic regression analysis showed that an increase in CAP (odds ratio [OR]=1.08, 95% confidence interval [CI]: 1.03 — 1.13, P<0.05), an increase in age (OR=1.02, 95%CI: 1.01 — 1.04, P<0.05), male sex (OR=1.77, 95%CI: 1.19 — 2.64, P<0.05), an increase in HBV DNA (OR=1.35, 95%CI: 1.15 — 1.57, P<0.001), an increase in aspartate aminotransferase (OR=1.02, 95%CI: 1.01 — 1.03, P<0.001), and an increase in gamma-glutamyl transpeptidase (OR=1.00, 95%CI: 1.00 — 1.01, P=0.028) were independent influencing factors for hepatic fibrosis. The risk of hepatic fibrosis in S3 patients was higher than that in patients without steatosis (OR=5.05, 95%CI: 2.48 — 10.29, P<0.001). ConclusionThere is a lower level of HBV replication in CHB patients comorbid with MASLD. Hepatic steatosis is associated with HBV-related virological markers and the progression of hepatic fibrosis, and severe fatty liver disease may promote the progression of hepatic fibrosis in CHB patients.

BackgroundNegative emotions are core predictors of adolescent mental health. While existing research has predominantly focused on the impact of risk factors such as negative life events and rumination on adolescents' emotions, the protective role of the family, particularly parental involvement, has received less attention. Consequently, the integrated mechanism connecting negative life events, rumination, parental involvement and negative emotions remains insufficiently clarified. ObjectiveTo elucidate the mechanisms linking negative life events to negative emotions in adolescents, and to verify the mediating role of rumination and the moderating role of parental involvement, so as to provide a theoretical basis for relevant prevention and intervention. MethodsA cross-sectional study was conducted in June 2025. A total of 600 adolescents from a middle school in Liangshan Yi Autonomous Prefecture, Sichuan Province, were recruited through cluster random sampling. Participants completed the Adolescent Self-rating Life Events Checklist (ASLEC), the Rumination Response Scale (RRS), parental involvement subscale of the Perception of Parents Scales (POPS), and the Chinese short version of Depression Anxiety and Stress Scale (DASS-21). Pearson correlation analysis was performed to examine the correlations among all variables. Model 4 and model 7 embedded in Process macro 4.1 were employed to separately test the mediating effect of rumination between negative life events and negative emotions of adolescents, as well as the moderating effect of parental involvement. ResultsUltimately, 534 valid questionnaires were obtained, yielding a valid response rate of 89.00%. ASLEC score and RRS score were positively correlated with DASS-21 scores (r=0.580, 0.706, P<0.01), and ASLEC score was also positively correlated with RRS score (r=0.583, P<0.01). Rumination acted as a partial mediator between negative life events and negative emotions, with an indirect effect of 0.531 (95% CI: 0.438–0.630), accounting for 55.60% of the total effect. Parental involvement significantly moderated the first stage of the mediating pathway (β=-0.109, P<0.05). ConclusionIn adolescents, rumination serves as a partial mediator in the relationship between negative life events and negative emotions, and parental involvement further moderates the predictive relationship from negative life events to rumination.

Puerariae Lobatae Radix and Puerariae Thomsonii Radix are the dried roots of Pueraria lobata and Pueraria thomsonii of the Leguminosae family, respectively. Since their separate inclusion in the 2005 edition of Pharmacopoeia of the People's Republic of China, the two herbs have been individually recorded. Although they share the same functions and indications, the required content of puerarin differs by a factor of up to eightfold between them. The current quality standard relies solely on a single indicator, puerarin, which fails to reflect the correlation between chemical constituents and core therapeutic effects. This has resulted in prominent issues of mixed use in clinical practice and production, thereby constraining the high-quality development of the industry. Modern research has demonstrated that Puerariae Lobatae Radix contains a comprehensive range and higher content of isoflavonoid constituents, while Puerariae Thomsonii Radix is rich in starch and polysaccharides. Puerariae Lobatae Radix exhibits stronger effects in antipyresis, cardiovascular and cerebrovascular protection, and central analgesia, while Puerariae Thomsonii Radix demonstrates greater advantages in anti-inflammation, hypoglycemia, and peripheral analgesia. Based on this, the chemical material bases of Puerariae Lobatae Radix and Puerariae Thomsonii Radix at both the macromolecule and micromolecule levels were systematically reviewed and compared. The pharmacodynamic material bases and mechanisms of action underlying their three core therapeutic effects, namely "relieving exterior syndrome and clearing heat", "promoting fluid production to quench thirst", and "dredging channels and activating collaterals", were summarized. The most highly correlated common metabolic pathway shared by both herbs for these three therapeutic effects is the arachidonic acid metabolic pathway, and their common core target is prostaglandin-endoperoxide synthase 2 (PTGS2). This review provided clinical application recommendations based on the therapeutic differences between the two herbs, elucidated the scientific connotation of their "same origin but different effects", and, grounded in the quality marker (Q-Marker), proposed the concept of efficacy-related Q-Marker based on "substance-efficacy-syndrome" association, as well as a novel strategy for efficacy-oriented quality evaluation. Preliminary screening of quality markers associated with different therapeutic effects was also conducted. This study aims to provide critical scientific evidence for the precise clinical application of Puerariae Lobatae Radix and Puerariae Thomsonii Radix, the improvement of quality standards, and the high-quality development of the industry.

Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Background:
and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT.
Methods:
Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery.
Results:
A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24).
Conclusion
Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective:To compare the clinical outcomes of reconstruction of oral and maxillofacial soft tissue defects using superficial circumflex iliac artery perforator flap (SCIA PF) and radial forearm free flap (RFF). Methods:A retrospective analysis was conducted on 90 patients with head, neck, and maxillofacial tumors who were treated in our department from June 2019 to January 2024. Patients were divided into two groups based on the surgical method used: the SCIA group(n=45), who underwent reconstruction with SCIA PF, and the RFF group(n=45), who received RFF reconstruction. Six months postoperatively, clinical efficacy was evaluated by comparing flap swelling, flap survival rate, and patient satisfaction. Oral function was assessed using standardized scoring systems before surgery, at 1 week, 3 months, and 6 months post-surgery. Hemorheological parameters, including high-shear viscosity(shear rate 200/s), low-shear viscosity(shear rate 30/s), plasma viscosity, erythrocyte aggregation index, and erythrocyte sedimentation rate(ESR), were also measured at each time point. Results:Compared with the RFF group, the SCIA group showed significantly larger flap size, longer flap harvesting and reconstruction times, earlier nasogastric tube removal and oral intake initiation, higher scores in all aspects of oral function, reduced flap edema and faster resolution, higher flap survival rates, and greater overall satisfaction (all P<0.05). During the follow-up period (preoperative, 1 week, 3 months, and 6 months post-surgery), hemorheological indices including high-and low-shear viscosity, plasma viscosity, erythrocyte aggregation index, and ESR progressively decreased in the SCIA group (P<0.05). In the RFF group, these parameters improved significantly by 6 months postoperatively compared with preoperatively and 1-week postoperatively, with a notable decrease in erythrocyte aggregation index at 6 months (P<0.05). Conclusion:Compared with RFF, SCIA PF provides larger flaps, better functional recovery, higher patient satisfaction, improved flap survival, fewer complications, and more favorable hemorheological profiles following reconstructive surgery for oral and maxillofacial defects.

Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe3O4 loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4+/CD8+ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

OBJECTIVES:
To investigate the therapeutic mechanism of Thesium chinense Turcz. (TCT) for antibiotic-associated diarrhea (AAD).
METHODS:
Network pharmacology, KEGG pathway enrichment analysis and molecular docking were used to identify the shared targets and genes of TCT and AAD, the key signaling pathways and the binding between the active components in TCT and the core protein targets. In a Kunming mouse model of AAD established by intragastric administration of lincomycin hydrochloride, the effects of daily gavage of 1% carboxymethyl cellulose sodium or TCT gel solutions at 1.5 g/kg and 3 g/kg (n=10) on body weight and diarrhea were observed. HE staining, ELISA, 16S rRNA sequencing, and Western blotting were used to examine pathologies, expression levels of IL-6 and TNF-α, changes in gut microbiota, and protein expressions of EGFR, p-EGFR, PI3K, p-PI3K, Akt, and p-Akt in the colon tissues of the mice.
RESULTS:
We identified a total of 66 active components of TCT and 68 core targets including EGFR, STAT3 and PIK3CA. KEGG pathway enrichment analysis suggested that the therapeutic effects of TCT was mediated primarily through the PI3K/Akt signaling pathway. Molecular docking showed that EGFR had the highest binding affinity with coniferin, and the EGFR-coniferin complex maintained a stable conformation at 10 ns, whose stability was also confirmed by Gibbs free energy analysis. In the mouse models of AAD, treatment with TCT significantly improved colonic tissue morphology, decreased colonic levels of TNF-α and IL-6, increased gut microbiota diversity, and modulated the relative abundances of the key genera including Lactobacillus and Bacteroides. TCT treatment also markedly reduced protein expressions of p-EGFR, p-PI3K and p-Akt in the colon tissues of the mice.
CONCLUSIONS
TCT can alleviate AAD in mice by modulating gut microbiota composition, regulating the EGFR/PI3K/Akt signaling pathway, and reducing TNF‑α and IL-6 expressions.
