Mitochondrial quality control (MQC) homeostasis serves as a fundamental mechanism in maintaining the mitochondrial structure and function. Dysregulation of MQC contributes to the progression of acute ischemic stroke (AIS) through multiple pathways including disturbances in energy metabolism, increased oxidative stress, and imbalances in mitochondrial fusion and fission. Drawing upon the traditional Chinese medicine (TCM) theory of the kidney governing Yin and Yang, this study innovatively proposes an integrative model of "Yin-Yang dynamic balance-MQC homeostasis" to elucidate the underlying pathophysiological mechanisms. Specifically, kidney Yang deficiency and decline result in reduced driving force, thereby inhibiting mitochondrial fusion. This leads to decreased efficiency of oxidative phosphorylation and impaired adenosine triphosphate (ATP) production. Conversely, when kidney Yin is dysfunctional and excessive phlegm-blood stasis accumulates, mitochondrial fission becomes hyperactive, causing rapid accumulation of reactive oxygen species (ROS) and intensified oxidative stress. The interplay between these two pathological states culminates in the central TCM pathogenesis—Yin-Yang imbalance and disordered Qi and blood-of AIS. To address this pathogenesis, a therapeutic strategy is proposed: tonifying the kidney as the primary intervention to restore MQC homeostasis, supplemented by resolving phlegm and removing blood stasis to interrupt the deleterious cycle of cerebral vascular damage. This work integrates the holistic perspective of TCM with contemporary molecular insights, offering precise intervention targets along the "kidney-mitochondria axis" for the prevention and treatment of AIS, while establishing a novel integrative paradigm for stroke management that bridges traditional and modern medicine. Future research should focus on elucidating the molecular mechanisms through which TCM regulates MQC in AIS and integrating classical TCM theories with evidence-based medicine to facilitate the translation of theoretical insights into clinical applications.

Objective:To investigate the effectiveness and safety of lacosamide (LCM) in pregnant women with epilepsy.Methods:A retrospective study was conducted involving 6 pregnant women with epilepsy who were treated with LCM at the Electroencephalogram Monitoring Center of the Department of Neurology, Xijing Hospital of Air Force Military Medical University from January 2022 to June 2023. Their electroclinical characteristics, seizures during pregnancy, breastfeeding, and follow-up were summarized.Results:The 6 patients were aged 22 to 30 years at the time of pregnancy. Three patients were treated with monotherapy, with a daily dose of LCM ranging from 150 mg to 200 mg, while the other 3 patients were treated with combination therapy, with a daily dose of 150 mg. The seizures of 5 patients decreased during pregnancy compared with progestation except for the case 2 without adherence to Medication. No malformations were observed in the newborns, with the Apgar scores of 9-10 at 1 minute and 5 minutes after birth. The infants showed normal growth, development, intelligence, and motor skills in subsequent assessments. Two patients breastfed their infants, 1 for 6 months and the other for 14 months by the last follow-up, with a daily LCM dose of 150 mg to 300 mg during the breastfeeding. No adverse reactions were observed in the infants.Conclusion:The addition of LCM during pregnancy and lactation showed good effectiveness and safety, with no observed birth malformations.

Objective:To explore the feasibility of using a simplified multiple sleep latency test (MSLT) for the diagnosis of narcolepsy type 1.Methods:Data from 158 patients with narcolepsy type 1 and 58 patients with non-type 1 narcolepsy who underwent overnight video-polysomnography (V-PSG) and MSLT in the Sleep Center, Department of Neurology, Xijing Hospital, Air Force Military Medical University from March 2019 to April 2024 were retrospectively collected. By reducing the number of naps in the MSLT, the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT was evaluated using the receiver operating characteristic (ROC) curve. The DeLong test was used to compare whether there was a statistically significant difference between the simplified MSLT and the standard 5-nap MSLT. Cohen′s Kappa statistical analysis was performed to compare the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT.Results:The age of the 216 patients who were ultimately enrolled was 17 (13, 30) years, including 152 male patients (70.4%). The Cohen′s Kappa between the simplified 3-nap MSLT and the standard 5-nap MSLT was 0.875, which was 0.903 between the simplified 4-nap MSLT and the standard 5-nap MSLT (Bonferroni-corrected, both P0.001), indicating high and statistically significant agreement for both simplified protocols with the standard test. However, the DeLong test revealed that the area under the curve of the standard 5-nap MSLT (0.900, 95% CI 0.863-0.938) differed significantly from that of the simplified 3-nap MSLT (0.860, 95% CI 0.817-0.904; P0.05), whereas no significant difference was observed between the standard 5-nap MSLT and the simplified 4-nap MSLT (0.876, 95% CI 0.834-0.918; P0.05). Consequently, performing only the first 4 naps was sufficient for diagnosing narcolepsy type 1. Conclusion:The simplified 4-nap MSLT, specifically the first to fourth naps, may be used for the diagnosis of narcolepsy type 1.

Epileptic seizure classification serves as an essential tool for evaluating seizures in clinical practice. In 2025, the International League Against Epilepsy updated the classification framework for epileptic seizures. An interpretation of the key updates is provided, with detailed content presented below: "onset" is removed from the names of the main seizure classes; consciousness is used as a classifier instead of awareness; the dichotomy of motor and non-motor is replaced by observable vs nonobservable manifestations; epileptic negative myocionus is recognized as a seizure type, to clarify the key updates to facilitate better application of the consensus in clinical practice.
