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.

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.

Identifying drug-drug interactions (DDIs) is essential to prevent adverse effects from polypharmacy. Although deep learning has advanced DDI identification, the gap between powerful models and their lack of clinical application and evaluation has hindered clinical benefits. Here, we developed a Multi-Dimensional Feature Fusion model named MDFF, which integrates one-dimensional simplified molecular input line entry system sequence features, two-dimensional molecular graph features, and three-dimensional geometric features to enhance drug representations for predicting DDIs. MDFF was trained and validated on two DDI datasets, evaluated across three distinct scenarios, and compared with advanced DDI prediction models using accuracy, precision, recall, area under the curve, and F1 score metrics. MDFF achieved state-of-the-art performance across all metrics. Ablation experiments showed that integrating multi-dimensional drug features yielded the best results. More importantly, we obtained adverse drug reaction reports uploaded by Xiangya Hospital of Central South University from 2021 to 2023 and used MDFF to identify potential adverse DDIs. Among 12 real-world adverse drug reaction reports, the predictions of 9 reports were supported by relevant evidence. Additionally, MDFF demonstrated the ability to explain adverse DDI mechanisms, providing insights into the mechanisms behind one specific report and highlighting its potential to assist practitioners in improving medical practice.

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.

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.

ObjectiveTo compare the therapeutic effects of carvedilol alone and carvedilol combined with endoscopic variceal ligation (EVL) in the prevention of re-bleeding from gastroesophageal varices, and to provide strategies for clinical treatment. MethodsWe retrospectively included 178 patients who had received carvedilol alone or carvedilol plus EVL to prevent gastroesophageal variceal re-hemorrhage from October 2010 to June 2023. They were divided into carvedilol alone group (47 cases) and carvedilol+EVL group (131 cases). Between-group comparisons were conducted using the paired t test for normally distributed continuous data, the Mann-Whitney U test for non-normally distributed continuous data, and the chi-square test for categorical data. A Cox proportional hazards model was employed for univariable and multi-variable analyses. The cumulative incidence rates of re-bleeding and mortality were estimated using the Kaplan-Meier method. The baseline characteristics of the two groups were matched through propensity score matching (PSM) to reduce selection bias and enhance the credibility of causal inference. ResultsThe re-bleeding rate of the carvedilol+EVL group was significantly lower than that of the carvedilol alone group (10-year cumulative incidence: 29.8% vs 36.2%, hazard ratio [HR]=0.505, 95% confidence interval [CI]: 0.292 — 0.847, P=0.015). There was no significant difference in liver-related mortality (10-year cumulative incidence: 21.3% vs 21.4%, HR=0.799, 95%CI: 0.406 — 1.578, P=0.518). The results were stable with PSM analysis. The Cox regression analysis revealed that creatinine was an independent risk factor affecting re-bleeding (HR=1.004, 95%CI: 1.001 — 1.008, P=0.011) and liver-related mortality (HR=1.004, 95%CI: 1.001 — 1.007, P=0.019). ConclusionCarvedilol combined with EVL is better than carvedilol alone in the prevention of gastroesophageal variceal re-bleeding.
