Objective: To prepare the erythrocyte-liposome drug delivery system to enhance the therapeutic effect of drugs on tumors and inhibit tumor metastasis. Methods: This study prepared and characterized paclitaxel (PTX)-plerixafor (AMD3100) liposomes (Lips), developed the erythrocyte-liposome drug delivery system, and evaluated its targeting efficiency and therapeutic efficacy through a series of in vitro cellular and in vivo animal experiments. Results: The particle size of PTX-AMD-Lips was (186.4±0.83) nm. Drug encapsulation efficiency of PTX-AMD-Lips was (75.50±5.27)% for PTX and (88.31±2.45)% for AMD. The Binding efficiency between RBC and liposomes in the drug delivery system was (69.93±2.55)%. Vitro cellular experiments revealed that PTX-AMD-Lips significantly inhibited tumor cell migration. In vivo animal experiments, the erythrocyte-liposome drug delivery system significantly increased drug accumulation in the lungs. At the experimental endpoint, the quantitative fluorescence signal of tumor size measured (4.04±0.44)×10
for the PTX-Lips group, and (5.14±3.40)×10
for the RBC-PTX-AMD-Lips group. Conclusion: The erythrocyte-liposome drug delivery system could enhance the lung-specific targeting capability of liposomes, kill tumor cells and suppress further metastasis effectively.

In the period of digital transformation of the medical service model, maintaining algorithm justice for medical artificial intelligence possesses multiple value implications. However, practical dilemmas exist at different stages of achieving this value goal. At the initial stage of diagnosis and treatment decision-making, there is a risk of imbalance in patients’ rights and interests, such as weakened effectiveness of patients’ right to informed consent, as well as low synergy between rights and interests protection and technological innovation. In the process of diagnosis and treatment decision-making, the algorithmic model is constrained by the technological bottleneck in the underlying application, deviating from the legal track of technological neutrality. After the diagnosis and treatment decision-making is generated, it triggers a crisis in the remedy of patients’ rights and interests and breeds the phenomenon of an ambiguous definition of subject qualification and attribution principle. In this regard, it is essential to establish a preemptive safeguard system focusing on the protection of patients’ rights and interests, set technological fairness standards, and shape review norms of technological neutrality. The aim is to ensure the equalization of remedy channels for patients’ rights and interests, promote the fairness in the proportion of responsibilities among multiple subjects, and thereby safeguard the digital justice in the field of intelligent diagnosis and treatments.

ObjectiveTo investigate the mechanism by which modified Shengjiangsan (MSJS) improves diabetic kidney disease (DKD) by activating mitochondrial autophagy. MethodsSixty SPF-grade male Sprague-Dawley rats aged 7-8 weeks were selected. A DKD model was established using a high-sugar, high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). After successful modeling, the rats were randomly divided into six groups: a normal control group, a model group, low-, medium-, and high-dose MSJS groups (7.7, 15.4, 30.8 g·kg-1, respectively), and an irbesartan group (0.384 g·kg-1). Each group received either normal saline or the corresponding drug by gavage once daily for 28 consecutive days. Blood glucose, body weight, and kidney weight were recorded. Serum creatinine (SCr) and blood urea nitrogen (BUN) levels were detected using an automatic blood analyzer. Enzyme-linked immunosorbent assay (ELISA) was used to determine urinary microalbumin (mALB), and serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). Histopathological changes in renal tissues were observed using hematoxylin-eosin (HE) staining, periodic acid-Schiff (PAS) staining, and transmission electron microscopy (TEM). The expression levels of mitochondrial autophagy-related proteins in renal tissues were analyzed by Western blot. Immunofluorescence co-localization was employed to detect the co-expression of microtubule-associated protein 1 light chain 3 beta (LC3B) and cytochrome c oxidase subunit Ⅳ (COX Ⅳ). ResultsCompared with the normal control group, the model group exhibited significant increases in renal index, blood glucose, and 24-hour urinary microalbumin (24 h mALB) (P<0.05, P<0.01). The levels of serum SCr and BUN were significantly elevated (P<0.01), and the serum levels of TNF-α, IL-1β, and IL-6 were markedly upregulated (P<0.01). Histopathological examination revealed glomerular hypertrophy, mesangial expansion and increased deposition, podocyte foot process flattening and fusion, a decreased number of autophagosomes accompanied by mitochondrial swelling, vacuolar degeneration of renal tubular epithelial cells, and inflammatory cell infiltration in the renal interstitium. The expression levels of autophagy-related proteins LC3B, PTEN-induced putative kinase 1 (PINK1), and E3 ubiquitin-protein ligase (Parkin) were significantly decreased (P<0.05, P<0.01), while expression of the selective autophagy adaptor protein p62 was significantly increased (P<0.01). Immunofluorescence signal intensity and LC3B-COX Ⅳ co-expression were both diminished. Compared with the model group, the MSJS treatment groups and the irbesartan group showed significant reductions in renal index, blood glucose, and 24 h mALB (P<0.05, P<0.01). The serum SCr and BUN levels decreased significantly (P<0.05) and TNF-α, IL-1β, and IL-6 levels were significantly downregulated (P<0.05, P<0.01). Histopathological damage was alleviated, including reduced glomerular hypertrophy, decreased mesangial deposition, and attenuated podocyte foot process fusion. The number of autophagosomes increased, and mitochondrial swelling was improved. The expression levels of LC3B, PINK1, and Parkin in renal tissues were significantly upregulated, whereas p62 expression was significantly downregulated (P<0.05, P<0.01) in MSJS groups. Immunofluorescence signal intensity was enhanced, and LC3B-COX Ⅳ co-expression was increased. ConclusionMSJS alleviates the inflammatory response in DKD rats and exerts renal protective effects by regulating the PINK1/Parkin signaling pathway and activating mitochondrial autophagy.

Adoptive cell transfer (ACT) shows significant efficacy against hema-tological malignancies but is limited in solid tumors due to poor homing, immunosuppre-ssion, and potential toxicity. Biomaterials spanning from nano- to macroscales-including nanoparticles, microspheres/micropatches, and hydrogels-offer unique advantages for ex vivo cell engineering, in vivo delivery, and modulation of the tumor microenvironment. Specifically, nanoparticles enable gene delivery, artificial antigen-presenting cell engi-neering, and immune microenvironment remodeling. Microspheres/micropatches improve immune cell expansion, targeted activation, and localized retention. Hydrogels enhance ACT via in situ genetic engineering, 3D culture support, and cytokine co-delivery. This review summarizes advances in biomaterial-enhanced ACT, highlighting their potential to improve delivery efficiency, amplify antitumor responses, and reduce toxicity. These insights may accelerate the clinical translation of ACT for solid tumors.

Objective:To investigate the potential characteristic manifestations and application value of the Dynamic Visual Acuity Test(DVAT) in vestibular migraine(VM). Methods:A total of 50 VM patients(case group) and 50 healthy subjects(control group) diagnosed at the Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Shanxi Medical University between November 1, 2023, and December 31, 2024, were enrolled. The case group underwent DVAT, video head impulse test(vHIT), caloric test, and Dizziness Handicap Inventory(DHI) assessment, whereas the control group only received DVAT. Group-based analyses were conducted to examine the effect of age on Dynamic Visual Acuity Loss(DVALoss), as well as the correlations of DVALoss with vestibular function tests and DHI scores. Results:DVALoss in the case group was significantly higher than that in the control group(P<0.001). In both groups, age was significantly and positively correlated with DVALoss(P<0.001). Within the case group, DVALoss was strongly and positively correlated with DHI scores(r=0.807, P<0.001); it was negatively correlated with the vestibulo-ocular reflex(VOR) gain in vHIT, though without clinical significance, and showed no significant association with the caloric test. Age and DVALoss collectively accounted for 71.3% of the variance in DHI scores(R²=0.713), with age exerting a relatively minor actual impact. Conclusion:DVAT can sensitively identify the core functional impairments of VM. DVALoss, as a direct functional reflection of the pathological mechanism of VM, is strongly correlated with DHI scores. Incorporating DVALoss into standardized assessments may provide an objective basis for the diagnosis and management of VM.
