ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke (AIS) patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method,the patients were assigned into a control group (32 cases) and an observation group (31 cases). The control group received conventional Western medical treatment,and the observation group took 200 mL Tongnaoyin after meals,twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment,the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans,rKep,and rVe values were obtained from the region of interest (ROI) of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment,the NIHSS and mRS scores declined in both groups,and the observation group had lower scores than the control group (P<0.05). After treatment,the rKtrans and rVe in the observation group were lower than those in the control group (P<0.01). ConclusionCompared with conventional Western medical treatment alone,conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients,thereby ameliorating neurological impairment after AIS to improve the prognosis.

BACKGROUND:
The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China.
METHODS:
This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences.
RESULTS:
Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n = 278] vs . 43.7% [ n = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses.
CONCLUSION
This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

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.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and memory loss, with few effective treatments currently available. The multifactorial nature of AD, shaped by genetic, environmental, and biological factors, complicates both research and clinical management. Recent advances in artificial intelligence (AI) and multi-omics technologies provide new opportunities to elucidate the molecular mechanisms of AD and identify early biomarkers for diagnosis and prognosis. AI-driven approaches such as machine learning, deep learning, and network-based models have enabled the integration of large-scale genomic, transcriptomic, proteomic, metabolomic, and microbiomic datasets. These efforts have facilitated the discovery of novel molecular signatures and therapeutic targets. Methods including deep belief networks and joint deep semi-non-negative matrix factorization have contributed to improvements in disease classification and patient stratification. However, ongoing challenges remain. These include data heterogeneity, limited interpretability of complex models, a lack of large and diverse datasets, and insufficient clinical validation. The absence of standardized multi-omics data processing methods further restricts progress. This review systematically summarizes recent advances in AI-driven multi-omics research in AD, highlighting achievements in early diagnosis and biomarker discovery while discussing limitations and future directions needed to advance these approaches toward clinical application.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [15N2]-cystine and [13C5]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Tic disorders in children refer to the neurodevelopmental disorders usually occurring in childhood and adolescence.Guided by the theory of five-zang-organ correlation,Professor Li Yirui approaches the treatment of tic disorders in children and comorbidities primarily from the perspective of liver-spleen disharmony,and points out that the pathogenesis is due to liver-spleen disharmony,wind-phlegm disturbance,and mutual involvement of the five zang organs.In clinical practice,Professor Li established the therapeutic principle of regulating the liver and spleen,extinguishing wind,and resolving phlegm,and adopted the four liver-regulating methods(calming liver,soothing liver,clearing liver,and softening liver)to extinguish wind and stop tics,as well as the four spleen-regulating methods(replenishing spleen,activating spleen,awakening spleen,and dredging spleen)to strengthen body resistance and support healthy qi.The self-formulated Fupi Xifeng Decoction(composed of Pseudostellariae Radix,Atractylodis Macrocephalae Rhizoma,Poria,Glycyrrhizae Radix et Rhizoma,Bupleuri Radix,Paeoniae Radix Alba,Uncariae Ramulus cum Uncis,Gastrodiae Rhizoma,Pinelliae Rhizoma Praeparatum,Citri Reticulatae Pericarpium,Os Draconis,etc.)serves as the basic formula,herbs directing to the affected regions were flexibly used,and insect drugs were occasionally adopted for refractory cases.The treatment for tic disorders in children focus on simultaneous regulation of the five zang-organs by modified use of herbs for dispersing wind and benefiting lung,tranquilizing heart and calming spirit,and supplementing liver and kidney to address comorbidities and secondary symptoms.Additionally,integrated internal-external treatment,relieving the discomforts physically and mentally,and family-centered comprehensive care are also taken into account to achieve optimal outcomes.

Objective:To investigate the clinical outcomes of total knee arthroplasty (TKA) combined with the modified “overlap” technique in the treatment of end-stage knee osteoarthritis with fixed patellar dislocation.Methods:This is a retrospective case series study. Clinical data of 19 patients (22 knees) who underwent TKA combined with the modified “overlap” technique for the treatment of end-stage knee osteoarthritis with permanent patellar dislocation from January 2011 to January 2022 in the Department of Orthopaedics, the First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed. The cohort included 5 males (6 knees) and 14 females (16 knees), with an age of (60.6±12.2) years (range:33 to 77 years) and a body mass index of (25.4±4.1) kg/m2 (range:20.0 to 33.0 kg/m2). Among them, 11 cases (12 knee) had valgus deformity, with Keblish classification showing mild in 2 cases (2 knees), moderate in 6 cases (6 knees), and severe in 4 cases (4 knees). All cases were treated using a medial parapatellar approach, with lateral retinaculum release combined with the “overlap” technique to restore the patellar trajectory. Knee function was evaluated using the American Knee Society (KSS) Score. Paired sample t tests were used for intergroup comparisons. Results:All patients successfully completed the surgery. Postoperatively, patellar dislocation, knee valgus deformity, flexion contracture deformity, and extensor lag were all corrected. All patients were followed up, with a follow-up duration of (63.8±35.2) months (range:24 to 136 months). One patient experienced periprosthetic infection 2 weeks postoperatively, 1 patient had recurrent patellar dislocation 2 months postoperatively, 1 patient developed knee stiffness 3 months postoperatively and underwent closed manipulation. No other patients exhibited signs of patellar dislocation or subluxation. At the last follow-up, the KSS clinical score improved from (36.4±12.7) points preoperatively to (83.4±6.3) points postoperatively ( t=-15.15, P<0.01), and the KSS functional score improved from (30.7±11.1) points preoperatively to (77.6±8.3) points postoperatively ( t=-14.37, P<0.01). The range of motion of the knee increased from 81.7°±19.6° preoperatively to 107.6°±12.5° postoperatively ( t=-4.85, P<0.01). Conclusion:TKA combined with the modified “overlap” technique is an effective surgical option for the treatment of end-stage knee osteoarthritis with permanent patellar dislocation, demonstrating satisfactory clinical outcomes.

ObjectiveTo investigate the effects of Jiaohong pills (JHP) and its prescription, Pericarpium Zanthoxyli (PZ) and Rehmanniae Radix (RR) cognitive dysfunction in scopolamine-induced Alzheimer's disease (AD) mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ, RG and JHP, respectively. The effects of JHP and its formulations were investigated by open field test, water maze test, object recognition test, avoidance test, cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry (UPLC Q-Exactive Orbitrap MS). ResultThe behavioral data showed that, compared with the model group, the discrimination indexes of the high dose of JHP, PZ and RR groups was significantly increased (P<0.05). The staging rate of Morris water maze test in the PZ, RR, high and low dose groups of JHP was significantly increased (P<0.05, P<0.01), the crossing numbers in the PZ, JHP high and low dose groups were significantly increased (P<0.05, P<0.01); the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups (P<0.01), and the error latencies were significantly increased in the JHP and its prescription drug groups (P<0.01). Compared with the model group, the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased (P<0.05, P<0.01), and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased (P<0.05), and the level of acetylcholine was significantly increased (P<0.01). At the same time, the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly (P<0.05, P<0.01). The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group, which were involved in neurotransmitter metabolism, energy metabolism, oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction, regulate cholinergic system, and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter, energy, amino acid metabolism, and improvement of oxidative stress.

ObjectiveTo study the plasma pharmacokinetics and tissue distribution of five representative components in Wujiwan, and to illustrate the difference of metabolism and tissue distribution before and after compatibility. MethodHealthy male SD rats were divided into four groups, including Wujiwan group(A group, 62.96 g·L-1), Coptidis Rhizoma group(B group, 38.4 g·L-1), processed Euodiae Fructus group(C group, 5.88 g·L-1) and fried Paeoniae Radix Alba group(D group, 18.68 g·L-1), with 65 rats in each group, and were administered the drugs according to the clinical dose of decoction pieces converted into the dose of the extracts. Then plasma, liver, small intestine and brain were taken at pharmacokinetic set time in each group after administration. Ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry was developed for the quantitative analysis of five representative components[berberine(Ber), palmatine(Pal), evodiamine(Evo), rutecarpine(Rut) and paeoniflorin(Pae)] in Wujiwan, their concentrations in plasma, liver, small intestine and brain were detected at different time, plasma samples were processed by protein precipitation, and tissue samples were pretreated by protein precipitation plus liquid-liquid extraction. Non-atrioventricular model was used to calculate the pharmacokinetic parameters of each component, and the parameters of each group were compared. ResultPharmacokinetic results of A group showed that area under the curve(AUC0-t) of the five representative components were ranked as follows:Ber and Pal were small intestine>liver>blood, Evo and Rut were liver>small intestine>plasma, Pae was small intestine>plasma, which was not detected in the liver, no other components were detected in brain except for Ber. In comparison with plasma and other tissues, peak concentration(Cmax) of Ber, Pal, Evo, and Rut were the highest and time to peak(tmax) were the lowest in the liver of A group. In plasma, the AUC0-t and Cmax of Evo and Rut were increased in A group compared with C group, tmax of Pea was elevated and its Cmax was decreased in A group compared with D group. In the liver, compared with B-D groups, Cmax values of 5 representative components except Pae were elevated, AUC0-t of Pae was decreased and AUC0-t of Evo and Rut were increased in the A group. In the small intestine, half-life(t1/2) of each representative components in A group was elevated and tmax was decreased, and Cmax of each representative ingredient except Pal was decreased, AUC0-t values of Ber and Pal were increased, whereas the AUC0-t values of Evo and Rut were decreased. ConclusionThe small intestine, as the effector organ, is the most distributed, followed by the liver. The pharmacokinetic parameters of the representative components in Wujiwan are changed before and after compatibility, which is more favorable to the exertion of its pharmacodynamic effects.
