ObjectiveTo explore the mechanism by which Yizhi Qingxin prescription improves mitochondrial dysfunction in Alzheimer's disease (AD) through regulating mitochondrial Ca2+ homeostasis and kinetic balance based on the protein kinase A (PKA)/calcineurin (CaN) signaling pathway. MethodsSixty three-month-old amyloid precursor protein (APP)/presenilin 1 (PS1) double transgenic mice were randomly divided into a model group, a donepezil group(0.65 mg·kg-1), a low-dose Yizhi Qingxin prescription group (YQF-L,2.6 g·kg-1), a medium-dose Yizhi Qingxin prescription group (YQF-M,5.2 g·kg-1), and a high-dose Yizhi Qingxin prescription group (YQF-H,10.4 g·kg-1), with 12 mice in each group. Twelve C57BL/6J mice with the same genetic background served as a normal group. Each treatment group received gavage administration daily, with the model and normal groups receiving equal volume of physiological saline. Intervention continued for 12 consecutive weeks. The learning and memory abilities of the mice were assessed using the novel object recognition (NOR) and Morris water maze (MWM) tests. Hematoxylin-eosin (HE)/Nissl staining was used to observe histopathological changes in the hippocampus. Transmission electron microscopy (TEM) was used to observe mitochondrial ultrastructure. Fluo-4 acetoxymethyl ester (Fluo-4 AM) Ca2+ probe was used to measure intracellular Ca2+ concentration in brain tissue. Western blot was used to determine the protein expression of PKA, CaN, sodium/calcium/lithium exchanger (NCLX), mitochondrial calcium uniporter (MCU), calmodulin (CaM), dynamin-related protein 1 (Drp1), and phosphorylated dynamin-related protein 1 (serine 637 site) [p-Drp1(S637)] in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to measure the expression of PKA, CaN, CaM, NCLX, MCU, and Drp1 mRNAs. ResultsCompared with those in the normal group, the recognition index (RI) of the model group decreased (P0.01), and the number of crossings through the original platform area, the duration of stay in the target quadrant, and the distance were reduced (P0.01). The protein expression of PKA, NCLX, and p-DRP1 (ser637) significantly decreased (P0.05), and the mRNA expression of PKA and NCLX significantly decreased (P0.05). The escape latency (EL) was prolonged (P0.05), and the intracellular Ca2+ level significantly increased (P0.01). The protein expression of CaN, CaM, MCU, and Drp1, as well as the mRNA expression of CaN, MCU, and Drp1, significantly increased (P0.05). After intervention with Donepezil and Yizhi Qingxin prescription, compared with that in the model group, the RI of the treatment group significantly increased (P0.05), and the number of crossings through the platform and the duration of stay in the target quadrant significantly increased (P0.05). The protein expression of PKA, NCLX, and p-Drp1 (ser637) and the mRNA expression of PKA and NCLX significantly increased (P0.05). On the 4th and 5th days, the EL was shortened (P0.05), and the intracellular Ca2+ level decreased (P0.05). The protein expression of CaN, CaM, MCU, and Drp1 and the mRNA expression of CaN, MCU, and Drp1 significantly decreased (P0.05). ConclusionYizhi Qingxin prescription regulates the PKA/CaN pathway, upregulates the expression of PKA, NCLX, and p-Drp1 (ser637) proteins, reduces the expression of CaN, CaM, MCU, and Drp1 proteins, and regulates Ca2+ homeostasis and mitochondrial dynamic balance, thereby enhancing the spatial learning and memory abilities of AD mice.

In the context of the modernization of traditional Chinese medicine (TCM), the inheritance of the experiences of famous doctors faces significant challenges due to its complex nonlinear characteristics and dynamic evolution. There are still issues in the current inheritance system, such as the homogenization of talent cultivation models, lack of standardized mentoring practices, and monotonous evaluation method, which hinder the systematic inheritance and innovative development of famous doctors' experiences. Based on a systematic review of the current state of artificial intelligence (AI)-assisted inheritance of famous doctors' experiences, this study explores innovative pathways for deep integration of modern information technologies with famous doctors' experiences from key dimensions, including data authenticity assurance, interdisciplinary collaboration mechanisms, and the establishment of dynamic inheritance standards. It proposes a paradigm shift in the inheritance of TCM famous doctors' experiences in the AI era, aiming to build a new TCM inheritance system of "digital intelligence empowerment and cross-disciplinary innovation", providing theoretical support and practical pathways for the inheritance of famous doctors' experiences in TCM.

ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

Colorectal cancer (CRC) is one of the most common cancers, with its incidence ranking high among cancers. It stands as the second leading cause of cancer-related death worldwide. In the early stages, CRC lacks specific symptoms, and most patients are diagnosed at advanced stages, making it a major research focus in the field of gastrointestinal tumors. Currently, clinical CRC treatments face several common challenges, including high surgical risks, frequent metastasis and recurrence, drug resistance, and significant side effects from chemotherapy and radiation therapy. With the development and application of traditional Chinese medicine (TCM), it has been found that TCM and its active ingredients can effectively inhibit CRC cell proliferation, invasion, migration, and angiogenesis, and promote apoptosis and autophagy, thereby slowing the progression of CRC. This has become a key focus of CRC treatment research. Salvia Miltiorrhiza has multiple pharmacological effects, including activating blood circulation to dispel blood stasis, unlocking meridians to relieve pain, clearing heat to calm irritability, and cooling blood to reduce abscesses. It contains a variety of chemical components, including diterpenoids, phenolic acids, flavonoids, polysaccharides, nitrogen-containing compounds, steroids, and lactone compounds. This review summarized the molecular mechanisms of Salvia miltiorrhiza and its active ingredients in the treatment of CRC. It is found that these ingredients exert anti-CRC effects through various molecular mechanisms, including cell cycle arrest, promotion of apoptosis, inhibition of cell invasion and migration, induction of autophagy, suppression of tumor angiogenesis, and remodeling of the tumor microenvironment. The review aims to provide new insights for the drug development and clinical application of Salvia miltiorrhiza in CRC treatment.

The abnormal accumulation of neutrophil extracellular traps (NETs) can promote the initiation and progression of pancreatic cancer, which is considered a potential therapeutic target for this disease. The Miraculous Pivot·Inquiry About Statement (《灵枢·口问》) have recorded the concept of "defensive qi stagnation". Based on the recognition that the function of defensive qi is similar to the immune function of neutrophils, and combining traditional Chinese medicine theory with clinical practice, it is proposed that the abnormal accumulation of NETs may be a pathological product of "defensive qi stagnation", with the spleen being the critical site of pathology. Further exploring the application strategy of cleaning spleen and restoring defensive qi method in pancreatic cancer treatment, it is proposed to employ three approaches such as dredging method to eliminate spleen stagnation and inhibit pancreatic cancer proliferation, cleaning method to remove spleen dampness and suppress the inflammatory micro-environment, and tonifying method to strengthen Weiqi and to improve the immune microenvironment, which aims to provide new insights for the clinical treatment of pancreatic cancer with traditional Chinese medicine.

AIM: To examine how three distinct central positioning techniques for anterior capsulotomy-pupil center, limbus center, and lens apex-affect intraocular lens(IOL)placement and visual quality following femtosecond laser-assisted cataract surgery(FLACS).METHODS: A total of 36 patients(72 eyes)with age-related cataracts who underwent FLACS and ZCB00 aspherical IOL implantation at Aier Eye Hospital Medical Center, Anhui Medical University between January and December 2023 were included in this prospective study. Patients were divided into three groups based on the central positioning mode for anterior capsulotomy: pupil center, limbus center, and lens apex center groups. IOL alignment and displacement were evaluated using the Casia2 device, and the postoperative visual quality was assessed.RESULTS: At 1 d postoperatively, the IOL tilt for the pupil, limbus, and apex groups were 3.96°±1.51°, 4.63°±1.87°, and 3.90°±2.24°, respectively(F=1.07, P=0.35); IOL decentration values were 0.21±0.10 mm, 0.23±0.16 mm, and 0.21±0.12 mm, respectively(F=0.14, P=0.87); total higher-order aberrations were 0.32±0.40 μm, 0.56±0.61 μm, and 0.53±0.60 μm, respectively(F=1.38, P=0.26); and coma aberrations values were 0.13±0.10 μm, 0.16±0.15 μm, and 0.14±0.15 μm, respectively(F=0.3, P=0.74). All results obtained postoperative day 1 did not differ significantly. At 3 mo postoperatively, IOL tilt values were 5.42°±2.00°, 3.96°±1.44°, and 3.20°±1.19°, respectively(F=12.40, P<0.001); IOL decentration values were 0.33±0.07 mm, 0.23±0.11 mm, and 0.21±0.11 mm, respectively(F=4.99, P=0.008); total higher-order aberrations were 0.67±0.29 μm, 0.44±0.37 μm, and 0.42±0.19 μm, respectively(F=5.50, P=0.006); and coma aberrations values were 0.21±0.12 μm, 0.19±0.12 μm, and 0.12±0.11 μm, respectively(F=3.87, P=0.03). All results obtained 3 mo postoperatively were statistically significant.CONCLUSION: Using the lens apex as the central positioning mode for anterior capsulotomy in FLACS improves postoperative IOL stability and reduces postoperative IOL tilt and decentration. If the lens apex cannot be determined intraoperatively, the limbus center-positioning mode is recommended.

Objective:To develop an artificial intelligence(AI)-based sequential ultrasound-magnetic resonance imaging(US-MRI)diagnostic strategy to optimize the imaging workflow for ovarian masses.Methods:A total of 1 120 patients with pathologically confirmed ovarian masses who underwent both preoperative pelvic ultrasound and MRI between January 2021 and December 2023 at Women's Hospital,Zhejiang University School of Medicine were retrospectively included. Patients were randomly divided into the training( n=672)and internal test set( n=448)at a ratio of 6∶4. An external test set( n=128)was established at the Forth Affiliated Hospital of School of Medicine. Deep learning was used for automated segmentation of MRI lesions,followed by radiomic feature extraction and machine learning classification to construct both a US-MRI multimodal model and sequential US-MRI strategy. Diagnostic performance and potential healthcare cost-saving effects were evaluated across strategies. Results:In the internal test set( n=448),the AI-based sequential US-MRI strategy achieved a F1 score of 0.863 and a diagnostic accuracy of 82.14%,with no significant difference compared to the US-MRI multi-modal model( P>0.05). The sequential strategy identified 82 cases(18.30%,82/448)of patients as low-risk true negatives during initial ultrasound screening,suggesting a potential to reduce the need for MRI examinations in future clinical practice. In the external test set( n=128),the strategy achieved an F1 score of 0.800 and a confirmed diagnosis rate of 85.94%,with a theoretical reduction of 26.56%(34 cases)in MRI utilization while maintaining a diagnostic accuracy rate higher than that of the multi-modal model(82.18%). Conclusions:The AI-based US-MRI sequential diagnostic strategy demonstrates favorable diagnostic accuracy while offering the potential to optimize MRI utilization. This approach may enhance the efficiency of imaging resource allocation and reduce healthcare burden in the management of ovarian masses.
