ObjectiveTo investigate the ameliorative effects and related mechanisms of the Zuogui Jiangtang Shuxin prescription (ZJSP) on glucose and lipid metabolism disorders in MKR mice with diabetic cardiomyopathy (DCM), with a focus on elucidating its regulatory role on the adenosine monophosphate-activated protein kinase (AMPK)/forkhead box protein O1 (FoxO1)/cluster of differentiation 36 (CD36) signaling pathway and lipid deposition. MethodsFifty 8-week-old male MKR mice were fed a high-fat diet for four weeks and then intraperitoneally injected with streptozotocin (STZ) while maintaining a high-fat diet to establish a DCM model. The mice were randomly divided into the model group, the low-dose(14.43 g·kg-1)and high-dose(28.86 g·kg-1) ZJSP groups, and the metformin group (0.25 g·kg-1), with age-matched FVB mice as a normal control group. Each group received intragastric administration of normal saline or corresponding concentrations of ZJSP at equal volumes. After four weeks, fasting blood glucose (FBG) and cardiac function were measured. Blood was collected from the eyeballs under anesthesia to detect fasting insulin (FINS) and blood lipid levels. Myocardial tissue morphology was observed by hematoxylin-eosin (HE) staining, and lipid deposition in the heart was assessed using oil red O staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression levels of AMPK, FoxO1, and CD36 in myocardial tissues. Western blot was employed to detect the protein expression levels of AMPK, p-AMPK, FoxO1, p-FoxO1, and CD36. ResultsCompared with the control group, the model group showed significantly increased levels of FBG and FINS (P<0.01), elevated levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (P<0.01), and significantly decreased left ventricular ejection fraction (EF) and fractional shortening (FS) values (P<0.01). HE staining revealed marked cardiomyocyte hypertrophy, disarray, and widened intercellular spaces in myocardial tissues. Oil Red O staining showed extensive red deposition areas and fine lipid droplet accumulation in the myocardial tissue. AMPK mRNA expression was decreased, while FoxO1 and CD36 mRNA expressions were significantly increased (P<0.01). The p-AMPK/AMPK protein expression ratio in myocardial tissues was significantly reduced, while the p-FoxO1/FoxO1 protein expression ratio and CD36 protein expression levels were significantly increased (P<0.01). Compared with the model group, all treatment groups exhibited significantly reduced FBG (P<0.01), decreased FINS and blood lipid levels (TG, TC, LDL-C) (P<0.05, P<0.01), improved cardiac function (P<0.05), noticeable amelioration of myocardial histopathological morphology and lipid deposition, increased AMPK mRNA expression (P<0.01), with significantly downregulated FoxO1 and CD36 mRNA expressions (P<0.01), elevated p-AMPK/AMPK protein expression levels in myocardial tissue (P<0.05), significantly decreased p-FoxO1/FoxO1 ratios (P<0.01), and downregulated CD36 protein expression levels (P<0.05, P<0.01). ConclusionZJSP exerts a protective effect on the heart in type 2 DCM of MKR mice, and its mechanism may be associated with the regulation of the AMPK/FoxO1/CD36 signaling pathway.

Cancer remains a leading cause of global mortality, necessitating the development of advanced therapeutic strategies with enhanced efficacy and reduced systemic toxicity. Among promising bioactive agents, lactoferrin (LF)—a multifunctional iron-binding glycoprotein abundantly found in mammalian milk and exocrine secretions—has garnered significant interest for its potent and multifaceted anti-cancer properties. This review provides a comprehensive analysis of the current understanding of LF’s role in oncology, encompassing its structural biology, diverse mechanisms of action, and groundbreaking advancements in its application through nano-engineering. LF exerts anti-tumor effects through multiple pathways, including extracellular action, intracellular action, and immune regulation. It demonstrates a remarkable affinity for cancer cell membranes, binding to overexpressed anionic components such as glycosaminoglycans and sialic acids, as well as to specific receptors including the low-density lipoprotein receptor-related protein-1 (LRP-1). This selective binding facilitates targeted uptake. Upon internalization, LF orchestrates a direct assault by inducing cell-cycle arrest in phases such as G0/G1 or S phase through the modulation of key regulators including cyclins, CDKs, and p53. Furthermore, it promotes programmed cell death via apoptotic pathways, involving caspase activation and downregulation of anti-apoptotic proteins such as survivin. A more recently elucidated mechanism is the induction of ferroptosis, an iron-dependent form of cell death characterized by overwhelming lipid peroxidation. Beyond direct cytotoxicity, LF acts as a potent immunomodulator. It enhances natural killer (NK) cell activity, modulates T-lymphocyte populations, and crucially reprograms tumor-associated macrophages (TAMs) from a pro-tumor M2 state to an anti-tumor M1 state, thereby reversing the immunosuppressive tumor microenvironment (TME). The translation of LF’s potential has been significantly accelerated by nanotechnology. The inherent biocompatibility and natural tumor-targeting capabilities of LF make it an ideal platform for sophisticated drug-delivery systems. This review details various fabrication strategies for LF-based nanoparticles (NPs), including self-assembly, sol-in-oil emulsion, and electrostatic nanocomplexes, among others. Research demonstrates that nano-formulations not only protect LF from degradation but also enhance its bioactivity and anti-cancer potency. More importantly, LF NPs serve as versatile carriers for a wide array of therapeutic agents, including conventional chemotherapeutics, natural compounds, and imaging agents. These engineered systems enable synergistic therapy and facilitate site-specific delivery. Notably, the ability of LF to bind to receptors on the blood-brain barrier (BBB) has been leveraged to develop nano-systems for glioblastoma treatment. Other innovative designs utilize LF to modulate the TME—for instance, by alleviating tumor hypoxia to sensitize cells to radiotherapy and chemotherapy. Despite compelling pre-clinical evidence, the clinical translation of LF and its nano-formulations remains nascent. While early-phase trials have established a favorable safety profile for recombinant human LF, larger Phase III studies have yielded mixed results, underscoring the complexity of its action in humans. Key challenges include enhancing drug targeting, optimizing loading efficiency, ensuring batch-to-batch reproducibility, and achieving deep tumor penetration. Future research must focus on the rational design of next-generation LF-NPs. This entails developing standardized manufacturing protocols, engineering “smart” stimuli-responsive systems for targeted drug release in the TME, and constructing multi-targeting platforms. A concerted interdisciplinary effort is paramount to bridge the gap between bench and bedside. In conclusion, LF, particularly in its nano-engineered forms, represents a highly promising and versatile agent in the oncological arsenal, holding immense potential for precise and effective cancer therapy.

Objective To explore the clinical application value of dual-source CT (DSCT) in imaging evaluation after anterior cruciate ligament (ACL) injury and reconstruction. Methods A total of 93 patients with ACL injury confirmed in our hospital between December 2023 and December 2024 were enrolled as the research subjects. All patients underwent arthroscopic single-bundle anatomical reconstruction of ACL, as well as DSCT and multi-slice spiral CT (MSCT) examinations at 1 month after surgery. ACL scan parameters, bone tunnel aperture center, and radiation dose parameters (CT dose index volume, dose-length product, effective dose) under DSCT and MSCT were compared. At 3 months after surgery, according to postoperative curative effect by International Knee Documentation Committee (IKDC) scoring method, patients were divided into favorable outcome group (IKDC ≥ 70 points, n = 69) and unfavorable outcome group (IKDC < 70 points, n = 24). The two groups were compared for bone tunnel angles [angle between femoral tunnel and joint line (γ angle), angle between femoral tunnel and femoral shaft (θ angle), angle between tibial tunnel and tibial shaft (α angle), angle between tibial tunnel and joint line (β angle)]. The predictive value of bone tunnel angles under DSCT in poor prognosis of patients after ACL reconstruction was analyzed by receiver operating characteristic curves. Results The intraclass correlation coefficients for image quality of ACL length, ACL angle, long diameter of femoral attachment point, long diameter of tibial attachment point, Fx, Fy, Tx, Ty, γ angle, θ angle, α angle, and β angle were 0.812, 0.835, 0.823, 0.834, 0.836, 0.847, 0.841, 0.834, 0.835, and 0.864, respectively. The long diameters of femoral attachment point and tibial attachment point under DSCT were shorter than those under MSCT (P < 0.05), Tx and Ty were lower than those under MSCT (P < 0.05), CT dose index volume, dose-length product, and effective dose were lower than those under MSCT (P < 0.05). The γ angle and θ angle in the favorable outcome group were lower than those in the unfavorable outcome group (P < 0.05). Receiver operating characteristic curve analysis showed that after ACL reconstruction, the areas under the receiver operating characteristic curves of γ angle, θ angle, and their combination under DSCT for predicting poor prognosis were 0.711, 0.712, and 0.783, respectively, with sensitivities of 76.81%, 79.71%, and 92.75% as well as specificities of 70.83%, 75.00%, and 62.50%, respectively (P < 0.05). Conclusion DSCT can evaluate the poor prognosis of patients after ACL reconstruction through ACL scan parameters, bone tunnel aperture center, γ angle, and θ angle, which also can effectively reduce radiation dose.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

ObjectiveTo explore the regulatory effect and mechanism of Danggui Shaoyaosan combined with Yinchenhaotang on lipid metabolism in the mouse model of type 2 diabetes mellitus (T2DM) complicated with metabolic dysfunction-associated steatotic liver disease (MASLD) based on network pharmacology and animal experiments. MethodsTwenty-four MKR transgenic diabetic mice were randomly allocated into 4 groups: Model, low-dose (12.6 g·kg-1) Chinese medicine (concentrated decoction of Danggui Shaoyaosan combined with Yinchenhaotang), high-dose (25.2 g·kg-1) Chinese medicine, and Western medicine (metformin, 0.065 g·kg-1). Six FVB mice were used as the normal group. All groups were treated for 6 consecutive weeks. The mice in the drug treatment groups were administrated with corresponding agents by gavage, and those in the normal group and model group received the same volume of distilled water. Fasting blood glucose, body weight, liver weight, glucose tolerance, liver function indicators, blood lipid levels, and pathological changes in the liver were evaluated for each group. Network pharmacology was employed to analyze the targets and pathways of Danggui Shaoyaosan combined with Yinchenhaotang in the treatment of T2DM complicated with MASLD. Molecular biological techniques were used to verify the enriched key targets. ResultsCompared with the model group, each treatment group showed reduced fasting blood glucose, body weight, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and liver weight (P<0.01). The high-dose Chinese medicine group was superior to the low-dose group in reducing low-density lipoprotein (LDL), increasing high-density lipoprotein (HDL), and recovering glucose tolerance (AUC) and ALT (P<0.05), with the effect similar to that of the Western medicine group. Morphologically, Chinese medicine groups showed reduced lipid accumulation and alleviated pathological damage in the liver tissue, with the high-dose group demonstrating more significant changes. Network pharmacology results showed that Danggui Shaoyaosan combined with Yinchenhaotang may exert therapeutic effects through multiple targets such as fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), B-cell lymphoma-2 (Bcl-2), MYC oncogene (MYC), and interleukin-1β (IL-1β). Western blot showed that compared with the model group, the treatment groups demonstrated down-regulated protein levels of FAS and ACC (P<0.01) and up-regulated protein levels of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) and UCP1 (P<0.01). Compared with the low-dose Chinese medicine group, the high-dose Chinese medicine group exhibited down-regulated protein levels of FAS and ACC and up-regulated protein levels of PGC-1α and UCP1 (P<0.05). ConclusionDanggui Shaoyaosan combined with Yinchenhaotang has the effect of ameliorating T2DM complicated with MASLD and can improve the liver lipid metabolism by up-regulating the protein levels of Fas and ACC and down-regulating the protein levels of PGC-1α and UCP1.

In most types of erectile dysfunction, particularly in advanced stages, typical pathological features observed are reduced parenchymal cells coupled with increased tissue fibrosis. However, the current treatment methods have shown limited success in reversing these pathologic changes. Recent research has revealed that changes in autophagy levels, along with alterations in apoptosis and fibrosis-related proteins, are linked to the progression of erectile dysfunction, suggesting a significant association. Autophagy, known to significantly affect cell fate and tissue fibrosis, is currently being explored as a potential treatment modality for erectile dysfunction. However, these present studies are still in their nascent stage, and there are limited experimental data available. This review analyzes erectile dysfunction from a pathological perspective. It provides an in-depth overview of how autophagy is involved in the apoptotic processes of smooth muscle and endothelial cells and its role in the fibrotic processes occurring in the cavernosum. This study aimed to develop a theoretical framework for the potential effectiveness of autophagy in preventing and treating erectile dysfunction, thus encouraging further investigation among researchers in this area.

OBJECTIVE:
To investigate the expression levels of EZH2 and KMT2D in patients with diffuse large B-cell lymphoma (DLBCL) and their relationship with pathological features.
METHODS:
84 patients with DLBCL treated in our hospital from January 2021 to June 2022 were selected as the study subjects, and clinical characteristics such as sex, age and pathological classification of the patients were collected. Immunohistochemistry was used to detecet the expression of KMT2D and EZH2 proteins in tumor tissue cells of the DLBCL patients. The differential expression of KMT2D and EZH2 in subgroups of different sexes, ages, primary sites, clinical stages, Hans subtypes, etc. were compared. The correlation between the expression of KMT2D and EZH2 protein and BCL-6, CD79A was analyzed and validated through the interaction of protein molecular structures. We followed up and recorded the survival status of the patients for 12 months, and analyzed the factors that affect the mortality of DLBCL patients.
RESULTS:
The positive rate of KMT2D and EZH2 was high (over 95%) in DLBCL patients. There was no significant difference in the expression of EZH2 and KMT2D among subgroups of different sexes, ages and stages (P >0.05). However, patients with different levels of BCL-6 and CD79A expression showed differences in EZH2 and KMT2D expression (P < 0.05). EZH2 and KMT2D were positively correlated with BCL-6 (r =0.391, r =0.332) and CD79A (r =0.309, r =0.258), respectively, and there were interactions in the protein molecular structures. The risk factors for mortality in DLBCL patients include male sex (OR =1.106, 95%CI : 1.082-1.130, P < 0.001), stage II (OR =1.778, 95%CI : 1.567-2.016, P < 0.001), stage IV (OR =2.233, 95%CI : 2.021-2.467, P < 0.001), EZH2 positive (OR =2.762, 95%CI : 1.304-5.850, P =0.008), BCL-6 positive (OR =7.309, 95%CI : 1.340-39.859, P =0.022), age≥74 years (OR =3.080, 95%CI : 1.658-5.723, P < 0.001), and 63-73 years old (OR =2.400, 95%CI : 1.564-3.682, P < 0.001), while KMT2D positive (OR =0.180, 95%CI : 0.054-0.608, P =0.006) and 41-51 years old (OR =0.406, 95%CI : 0.274-0.603, P < 0.001) were factors which could reduce the risk of mortality.
CONCLUSION
EZH2 and KMT2D are highly expressed in patients with DLBCL, and they are positively correlated with BCL-6 and CD79A, and affect the prognosis of DLBCL patients.
