Atherosclerosis is a complex pathological condition resulting from lipid deposition, chronic inflammatory responses, and fibrosis, with a prolonged disease course and multifactorial etiology. Based on the traditional Chinese medicine (TCM) theory of accumulation syndrome, atherosclerosis can be classified under this category, with its pathogenesis involving phlegm, blood stasis, deficiency, and accumulation. This paper proposed a stage-based intervention strategy using the four therapeutic principles of "attacking, supplementing, dispersing, dissipating", and divided into six stages based on the pathological progression, including the stage of accumulation before formation, the stage of accumulation already formed, the stage of nucleus accumulation, the stage of nucleus accumulation decay, the stage of nucleus accumulation consolidation, and the stage of severe stenosis of nucleus. At different stages, the intervention focuses on reinforcing healthy qi and consolidating the root, tonifying the kidneys and spleen, dispersing and removing turbidity, removing phlegm stagnation, promoting qi circulation, dispersing accumulations and removing stasis, attacking accumulation and expelling stasis, directing the turbid downward and dispersing accumulation, and treatment would be adjusted based on specific symptoms, which provides a theoretical framework for the prevention and treatment of atherosclerosis with TCM.

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.

Journal of Pathology and Translational Medicine 2025;59(1):68-83
Background:
Nasopharyngeal carcinoma (NPC) is characterized by high programmed death-ligand 1 (PD-L1) expression and abundant infiltration of non-malignant lymphocytes, which renders patients potentially suitable candidates for immune checkpoint blockade therapies. Palate, lung, and nasal epithelium clone (PLUNC) inhibit the growth of NPC cells and enhance cellular apoptosis and differentiation. Currently, the relationship between PLUNC (as a tumor-suppressor) and PD-L1 in NPC is unclear.
Methods:
We collected clinical samples of NPC to verify the relationship between PLUNC and PD-L1. PLUNC plasmid was transfected into NPC cells, and the variation of PD-L1 was verified by western blot and immunofluorescence. In NPC cells, we verified the relationship of PD-L1, activating transcription factor 3 (ATF3), and β-catenin by western blot and immunofluorescence. Later, we further verified that PLUNC regulates PD-L1 through β-catenin. Finally, the effect of PLUNC on β-catenin was verified by co-immunoprecipitation (Co-IP).
Results:
We found that PLUNC expression was lower in NPC tissues than in paracancer tissues. PD-L1 expression was opposite to that of PLUNC. Western blot and immunofluorescence showed that β-catenin could upregulate ATF3 and PD-L1, while PLUNC could downregulate ATF3/PD-L1 by inhibiting the expression of β-catenin. PLUNC inhibits the entry of β-catenin into the nucleus. Co-IP experiments demonstrated that PLUNC inhibited the interaction of DEAD-box helicase 17 (DDX17) and β-catenin.
Conclusions
PLUNC downregulates the expression of PD-L1 by inhibiting the interaction of DDX17/β-catenin in NPC.

In the era of big data, neuroimaging and algorithmic analyses have propelled brain science research and brain mapping. Acupuncture, widely recognized as an effective surface stimulation therapy, has demonstrated therapeutic efficacy for various brain conditions such as stroke and depression. However, the mechanisms linking acupuncture to brain function and its modulatory effects on brain activity require systematic exploration. Additionally, there is an urgent need to scientifically reinterpret traditional meridian theory and enhance its clinical applicability. Therefore, we propose the initiative of constructing a "brain mapping atlas of meridian, collateral and body surface stimulation" to explore the patterns linking the therapeutic effects of stimulating the twelve meridians, eight extraordinary vessels, divergent channels, collateral channels, sinew channels, and skin regions to brain function. This initiative aims to provide a scientific interpretation of traditional Chinese medicine meridian theory and enhance its practical applicability. This paper begins by reviewing the current state of brain mapping. It then summarizes existing research on the relationship between acupuncture and the brain, highlighting the necessity of constructing this atlas. The paper further analyzes the methodologies and technical challenges involved. Finally, the potential applications of the brain mapping atlas of meridian, collateral and body surface stimulation, and its main significance in advancing traditional meridian theory to keep pace with the times are prospected.

In recent years, hybrid brain-computer interfaces (BCIs) have gained significant attention due to their demonstrated advantages in increasing the number of targets and enhancing robustness of the systems. However, Existing studies usually construct BCI systems using intense auditory stimulation and strong central visual stimulation, which lead to poor user experience and indicate a need for improving system comfort. Studies have proved that the use of peripheral visual stimulation and lower intensity of auditory stimulation can effectively boost the user's comfort. Therefore, this study used high-frequency peripheral visual stimulation and 40-dB weak auditory stimulation to elicit steady-state visual evoked potential (SSVEP) and auditory steady-state response (ASSR) signals, building a high-comfort hybrid BCI based on weak audio-visual evoked responses. This system coded 40 targets via 20 high-frequency visual stimulation frequencies and two auditory stimulation frequencies, improving the coding efficiency of BCI systems. Results showed that the hybrid system's averaged classification accuracy was (78.00 ± 12.18) %, and the information transfer rate (ITR) could reached 27.47 bits/min. This study offers new ideas for the design of hybrid BCI paradigm based on imperceptible stimulation.

PURPOSE:
To compare the effects of empirical and modified hemostatic resuscitation for liver blast injury combined with seawater immersion.
METHODS:
Thirty rabbits were subjected to liver blast injury combined with seawater immersion, and were then divided into 3 groups randomly (n = 10 each): group A (no treatment after immersion), group B (empirical resuscitation with 20 mL hydroxyethyl starch, 50 mg tranexamic acid, 25 IU prothrombin complex concentrate and 50 mg/kg body weight fibrinogen concentrate), and group C (modified resuscitation with additional 10 IU prothrombin complex concentrate and 20 mg/kg body weight fibrinogen concentrate based on group B). Blood samples were gathered at specified moments for assessment of thromboelastography, routine coagulation test, and biochemistry. Mean arterial pressure, heart rate, and survival rate were also documented at each time point. The Kolmogorov-Smirnov test was used to examine the normality of data distribution. Multigroup comparisons were conducted with one-way ANOVA.
RESULTS:
Liver blast injury combined with seawater immersion resulted in severe coagulo-fibrinolytic derangement as indicated by prolonged prothrombin time (s) (11.53 ± 0.98 vs. 7.61 ± 0.28, p<0.001), activated partial thromboplastin time (APTT) (s) (33.48 ± 6.66 vs. 18.23 ± 0.89, p<0.001), reaction time (R) (min) (5.85 ± 0.96 vs. 2.47 ± 0.53, p<0.001), decreased maximum amplitude (MA) (mm) (53.20 ± 5.99 vs. 74.92 ± 5.76, p<0.001) and fibrinogen concentration (g/L) (1.19 ± 0.29 vs. 1.89 ± 0.32, p = 0.003), and increased D-dimer concentration (mg/L) (0.38 ± 0.32 vs. 0.05 ± 0.03, p = 0.005). Both empirical and modified hemostatic resuscitation could improve the coagulo-fibrinolytic states and organ function, as indicated by shortened APTT and R values, decreased D-dimer concentration, increased fibrinogen concentration and MA values, lower concentration of blood urea nitrogen and creatine kinase-MB in group B and group C rabbits in comparison to that observed in group A. Further analysis found that the R values (min) (4.67 ± 0.84 vs. 3.66 ± 0.98, p = 0.038), APTT (s) (23.16 ± 2.75 vs. 18.94 ± 1.05, p = 0.001), MA (mm) (60.10 ± 4.74 vs. 70.21 ± 3.01, p < 0.001), and fibrinogen concentration (g/L) (1.68 ± 0.21 vs. 1.94 ± 0.16, p = 0.013) were remarkably improved in group C than in group B at 2 h and 4 h after injury. In addition, the concentration of blood urea nitrogen (mmol/L) (24.11 ± 1.96 vs. 21.00 ± 3.78, p = 0.047) and creatine kinase-MB (U/L) (85.50 ± 13.60 vs. 69.74 ± 8.56, p = 0.013) were lower in group C than in group B at 6 h after injury. The survival rates in group B and group C were significantly higher than those in group A at 4 h and 6 h after injury (p < 0.001), however, there were no statistical differences in survival rates between group B and group C at each time point.
CONCLUSIONS
Modified hemostatic resuscitation could improve the coagulation parameters and organ function better than empirical hemostatic resuscitation.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.
