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.

This study identified six novel azaphilones, isochromophilones G-L (1-6), and three novel biosynthetically related congeners (7-9) from Diaporthe sp. SCSIO 41011. The structures and absolute configurations were elucidated through comprehensive spectroscopic analyses combined with experimental and calculated electronic circular dichroism (ECD) spectra. Significantly, three highly oxygenated azaphilones contain an acetyl group at the terminal chain (4) or linear conjugated polyenoid moieties (5 and 6), which occur infrequently in the azaphilone family. Additionally, several compounds demonstrated inhibition of lipopolysaccharide (LPS)-induced nuclear factor kappa-B (NF-κB) activation in RAW 264.7 macrophages at 20 μmol·L^-1. The novel compound (1) effectively inhibited receptor activator of NF-κB ligand (RANKL)-induced osteoclast differentiation without exhibiting cytotoxicity in bone marrow and RAW 264.7 macrophages, indicating its potential as a promising lead compound for osteolytic disease treatment. This research presents the first documented evidence of azaphilone derivatives as inhibitors of RANKL-induced osteoclastogenesis.

Objective:To analyze the status of social support and the influencing factors of support utilization among general practitioners.Methods:An investigation on the status of social support and the influencing factors of support utilization was conducted among general practitioners (GPs) from 6 communities in Shanghai Minhang District selected by simple sampling method in February 2023. The investigation included a questionnaire survey containing basic information and intervention measures (emotional support, information support, tool support); and assessments of the Social Support Rate Scale (SSRS), Perceived Social Support Scale, General Self-Efficacy Scale, Quality of Work Life Scale, Trait Coping Style Scale, and Psychological Resilience Scale. The association of social support status with various characteristics of GPs and their perceived social support and trait coping style was analyzed, and the influencing factors of social support utilization were determined.Results:A total of 184 questionnaires were distributed and 184 valid questionnaires were collected, with an effective recovery rate of 100.00%. Among the 184 participants, 55 (29.89%) had a general level of social support, and 129 (70.11%) were satisfied with their social support. The total score of SSRS was (37.49±8.41), with the objective support dimension scoring (9.67±3.42), subjective support scoring (20.04±4.52), and support utilization scoring (7.77±2.09). Univariate analysis showed significant differences in social support levels among respondents with different marital status, number of children, emotional support, informational support, instrumental support, positive coping, negative coping, psychological resilience, compassion fatigue, general self-efficacy, and perceived social support status ( P<0.05). Multiple linear regression analysis indicated that marital status, family support, professional skills, positive coping, and negative coping were independent influencing factors of social support. Among these factors, being married, having family care support, professional titles and skills and positive coping had a positive impact on social support levels, while negative coping had a negative impact ( P<0.05). Further stepwise multiple linear regression analysis showed that friend support, positive coping and family care were positive influencing factors for support utilization, while negative coping was a negative influencing factor ( P<0.05). Conclusion:The levels of social support among GPs in Minghang district of Shanghai are relatively high. Marital status, family support, professional title and skills and positive coping are positive factors for social support; and friend support, positive coping and family support are positive factors for support utilization.

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.

Objective To explore the evaluation value of serum follistatin like protein 1(FSTL1)and glu-cose regulatory protein 78(GRP78)on disease severity and readmission in elderly patients with chronic ob-structive pulmonary disease(COPD).Methods A total of 100 elderly COPD patients(COPD group)treated in this hospital from March 2020 to May 2023 were selected as COPD group,and were divided into grade Ⅰ(35 cases),grade Ⅱ(46 cases)and grade Ⅲ(19 cases)according to the severity of the disease.Another 100 elderly volunteers who underwent physical examination during the same period were selected as the control group.Serum FSTL1 and GRP78 levels were detected by enzyme-linked immunosorbent assay(ELISA).Spearman and Pearson correlation were used to analyze the correlation between serum FSTL1 and GRP78 lev-els and general data.The evaluation value of serum FSTL1 and GRP78 levels in COPD patients on disease se-verity and readmission was analyzed by receiver operating characteristics(ROC)curve.Results Compared with the control group,serum levels of FSTL1 and GRP78 in COPD group were significantly increased(P＜0.05).Serum levels of FSTL1 and GRP78 in COPD patients increased with the severity of the disease(P＜0.05).Compared with non-readmission group,the serum levels of FSTL1 and GRP78 in readmission group were significantly increased(P＜0.05).Spearman correlation analysis showed that serum FSTL1 and GRP78 levels were positively correlated with smoking history,hypertension history and disease severity(P＜0.05).Pearson correlation analysis showed that serum FSTL1 and GRP78 levels were negatively correlated with arte-rial oxygen pressure(PaO2),the ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC),and the percentage of forced expiratory volume in the first second to expected value(FEV1％pred),with significance(P＜0.05),while it was positively correlated with the partial pressure of carbon diox-ide(PaCO2),with significance(P＜0.05).ROC curve analysis showed that serum FSTL1,GRP78 and their combined assessment of disease severity and readmitted area under the curve(AUC)were higher in COPD pa-tients,and the combination was significantly better than the single assessment(P＜0.05).Conclusion Serum levels of FSTL1 and GRP78 are significantly increased in COPD patients,which are correlated with the severi-ty of the disease and have a high value in evaluating the severity of the disease and readmission.

Objective:To summarize the clinical and electrophysiological characteristics of epilepsy patients with fixation-off sensitivity (FOS).Methods:Using "fixation-off sensitivity" and "epilepsy" as search terms, data were retrieved from the Electroencephalogram Monitoring Center Database of Xijing Hospital, Air Force Military Medical University. Information was collected on epilepsy patients with FOS who were seen at the Xijing Hospital Electroencephalogram Monitoring Center from March 2019 to May 2023. A retrospective analysis of video electroencephalograms and clinical information was conducted, along with follow-up. Single factor analysis and multi-factor Logistic regression analysis were used to analyze the risk factors affecting the prognosis of the patients.Results:A total of 78 patients met the inclusion criteria, including 43 females and 35 males; the age at first epilepsy onset was 12.00 (8.00, 15.25) years. Among these 78 patients, 46 were diagnosed with genetic generalized epilepsy, 11 with self-limited focal epilepy, 9 with familial cortical myoclonic tremor with epilepsy, 7 with developmental and epileptic encephalopathy, 3 with symptomatic epilepsy, and 2 with progressive myoclonic epilepsy. The fixation-off induction trial most commonly triggered seizures in epilepsy with eyelid myoclonia (EEM) patients, with eyelid myoclonia being the most common type of seizure. Twenty-five epilepsy patients with FOS showed a positive photoparoxysmal response, of whom 6 experienced photo-convulsive response. Sixty-eight patients completed follow-up with comprehensive clinical data. At the last follow-up, 45 patients had been free from tonic-clonic seizures for at least one year. A history of febrile seizures ( OR=20.559, 95% CI 2.179-193.997, P=0.008) and cognitive decline ( OR=3.752, 95% CI 1.118-12.588, P=0.032) were identified as risk factors for poor prognosis in epilepsy patients with FOS. The age of first epilepsy onset, the number of anti-seizure medications, and the intermittent photo stimulation trial results had no correlation with prognosis. Conclusions:FOS is more common in female epilepsy patients and can be observed in both generalized and focal epilepsy syndromes. EEM patients are prone to seizures during fixation-off induction trial, and the most common type of seizures is eyelid myoclonus seizure. Patients with epilepsy with FOS who have a history of febrile seizures and cognitive impairment tend to have poor prognosis.
