Depression, a mental health disorder, has emerged as one of the significant challenges in the global public health domain. Investigating the pathogenesis of depression and accurately assessing the symptomatic changes are fundamental to formulating effective clinical diagnosis and treatment strategies. Utilizing non-invasive brain imaging technologies such as functional magnetic resonance imaging and scalp electroencephalography, existing studies have confirmed that the onset of depression is closely associated with abnormal neural activities and altered functional connectivity in multiple brain regions. Magnetoencephalography, unaffected by tissue conductivity and skull thickness, boasts high spatial resolution and signal-to-noise ratio, offering unique advantages and significant value in revealing the abnormal brain mechanisms and neural characteristics of depression. This review, starting from the rhythmic characteristics, nonlinear dynamic features, and connectivity characteristics of magnetoencephalography in depression patients, revisits the research progress on magnetoencephalography features related to depression, discusses current issues and future development trends, and provides insights for the study of pathophysiological mechanisms, as well as for clinical diagnosis and treatment of depression.

BACKGROUND:As a common disease in middle-aged and elderly,osteoarthritis is difficult to cure,and the pathogenesis is not clear.Long non-coding RNA participates in the pathogenesis of osteoarthritis through many ways,such as regulating translation,promoting or inhibiting mRNA,and adsorbing miRNAs. OBJECTIVE:To review the types of common long non-coding RNA in osteoarthritis,and the influence of multiple long non-coding RNAs on the pathological factors related to osteoarthritis,to analyze the future application of long non-coding RNAs in osteoarthritis. METHODS:Literature retrieval was conducted in CNKI,WanFang Data,VIP database,PubMed,Web of Science and Sciencedirect databases,using the search terms of"osteoarthritis,degenerative joint disease,degenerative arthritis,OA,LncRNA,long non-coding RNA,long noncoding RNA,long intergenic non-coding RNA"in Chinese and English.All relevant literature published from 1976 and May 2024 was retrieved.After literature screening,induction,analysis and summary,93 articles were finally included for review. RESULTS AND CONCLUSION:This review collected 25 long non-coding RNAs that are well studied with osteoarthritis.Long non-coding RNAs,as a molecular sponge for miRNA,are competing endogenous RNAs to competitively adsorb miRNAs and then affect downstream targets.Long non-coding RNAs can regulate physiopathological processes such as chondrocyte apoptosis and proliferation,cartilage extracellular matrix degradation,and inflammatory responses.Long non-coding RNAs are expected to become a biomarker and potential therapeutic target for the clinical diagnosis and therapeutic prognosis of osteoarthritis,and it may become a new strategy for the clinical treatment of osteoarthritis in the future.

Objectives:To summarize the characteristics of Fabry′s disease with cardiac involvement.Methods:This was a single-center, cross-sectional, retrospective study. Patients with Fabry disease who were admitted to Zhongda Hospital Affiliated to Southeast University from January 2022 to March 2023 were included. Clinical data, laboratory results, electrocardiogram, echocardiography and cardiac magnetic resonance findings of enrolled patients were collected. Clinical presentations and imaging features of patients with Fabry′s disease with cardiac involvement were summarized and analyzed.Results:A total of 17 patients from 8 families were included, with 9 males and diagnosis age of (44.35±13.72) years. Cardiac involvement and other organ involvement were presented in all patients and the heart was the most vulnerable organ (17/17). 24 h electrocardiogram showed frequent sinus arrhythmia in 3 patients. Echocardiography showed reduced left ventricular ejection fraction in 1 patient, myocardial hypertrophy in 13 patients, and left ventricular wall thickness ≥13 mm in 10 patients. Mitral regurgitation was observed in 11 patients and tricuspid regurgitation in 12 patients. Two patients underwent two-dimensional speckle tracking echocardiography, both revealing reduced regional longitudinal strain of the left ventricle, primarily in the basal segments. Cardiac magnetic resonance showed reduced left ventricular ejection fraction in 2 patients, myocardial hypertrophy in 16 patients, and left ventricular wall thickness≥13 mm in 14 patients. T1 value was reduced in 16 patients, with late gadolinium enhancement observed in 9 patients and “pseudo-normalization” of T1 values in 1 patient. The most susceptible target organ besides the heart was the kidneys (14/17), followed by the central nervous system (9/17). Additional findings inclucling cutaneous angiokeratoma in 4 patients, peripheral neuropathy with burning pain and hypohidrosis or hyperhidrosis in 6 patients, and corneal vortex opacities in 2 patients.Conclusion:The main manifestations of cardiac involvement in Fabry′s disease are decreased cardiac function, left ventricular hypertrophy and myocardial fibrosis. Advanced imaging techniques such as two-dimensional speckle tracking, T1 Mapping, and late gadolinium enhancement are useful in detecting myocardial pathological changes of Fabry′s disease.

OBJECTIVE To investigate the protective effects of hydroxytyrosol hydroxybutyrate(HTHB)against cognitive impairment induced by acute sleep deprivation in mice and to explore the underlying mechanisms.METHODS Male C57BL/6J mice were assigned to the following groups:normal control,normal groups administered with HTHB 30,60 and 120 mg·kg-1 or hydroxytyrosol(HT 19.25,38.5 and 77 mg·kg-1),a sleep deprivation(SD)model group,and SD groups co-administered with the same doses of HTHB or HT.Acute sleep deprivation was induced for 72-96 h using a rotarod apparatus in all groups except the normal control and normal drug-treated groups.Based on dose-response assess-ments in the Y-maze and novel object recognition tests,the effective doses(HTHB 60 mg·kg-1 and HT 38.5 mg·kg-1)were selected for subsequent evaluation in the two-choice visual discrimination task that was performed in a subset of groups:normal control,normal+HTHB 60 mg·kg-1,normal+HT 38.5 mg·kg1,SD model,SD+HTHB 60 mg·kg-1,and SD+HT 38.5 mg·kg-1.Cognitive functions that were assessed included spatial working memory(Y-maze spontaneous alternation),object recognition memory(novel object recognition)and visual discrimination ability(two-choice visual discrimination task).Biochemically,levels of hippocampal reactive oxygen species(ROS)were quantified by ELISA while the ATP content was determined using a firefly luciferase-based assay.RESULTS In non-sleep-deprived mice,neither HTHB nor HT administration significantly altered locomotor activity,spatial working memory,object recognition memory,or visual discrimination performance.Following sleep deprivation,the model group displayed significant cognitive deficits,including reduced spontaneous alternation rate,lower novel object recognition indexes,and decreased accuracy in the visual discrimination task at 48 and 96 h.These impairments were accompanied by elevated hippocampal ROS levels and reduced ATP contents com-pared to the control group.Treatment with HT 38.5 and 77 mg·kg-1 significantly attenuated the deficit in spontaneous alternation,but did not affect other parameters.In contrast,HTHB at 60 and 120 mg·kg-1 produced broader restorative effects and significantly reversed impairment in both spontaneous alterna-tion and novel object recognition.Furthermore,HTHB at 60 mg·kg-1 significantly improved visual discrimination accuracy at 48 and 96 h,while lowering hippocampal ROS levels and increasing ATP contents.CONCLUSION HTHB effectively mitigates acute sleep deprivation-induced impairment in spatial working memory,object recognition memory,and visual discrimination in mice.This protection is likely mediated by the enhancement of mitochondrial antioxidant capacity and the restoration of energy metabolism.

Objectives:To establish a comprehensive system of Cardiovascular Academic Performance Evaluation(CAPE)and rank global TOP100 medical institutions in the fields of cardiovascular diseases(CVD). Methods:CVD-related terms were extracted from Medical Subject Headings(MeSH),Embase thesaurus(EMtrees)and International Classification of Diseases(ICD)by CVD-related professionals,as well as by librarians and information professionals.Terminology databases(named as Fuwai Subject Headings)were established,and nine sub-disciplines were proposed,including ischemic heart diseases,hypertension,vascular diseases,arrhythmia,pulmonary vascular diseases,heart failure,congenital heart diseases,cardiomyopathy,and valvular heart diseases.The mapping patterns of sub-discipline,cardiovascular terminology and entry terms were pre-defined.The CVD-related research literature published from January 1,2016 to December 31,2022 were retrieved from Web of Science,PubMed and Scopus.Based on this,metadata were fused and duplicates were excluded.Fuwai Subject Headings were searched and matched into four respects for each literature,including subject words,titles,keywords,and abstracts,which was used to generate an information table of"Position—CVD terminology—Frequency",and to calculate CVD correlation scores and sub-discipline scores.We standardized the names of medical institutions and scholars,and make a ranking system for CAPE based on original articles with strong cardiovascular correlation(correlation score≥4).When evaluating the science and technological performance for Chinese hospitals in cardiovascular diseases,National Natural Science Foundation Projects,authorized invention patents,prize achievements,research platforms,and registered data of drug clinical trials in Center for Drug Evaluation(CDE)were considered besides research papers. Results:During 2016 and 2022,1 545 103 CVD research literatures were found worldwide.After excluding meeting abstracts,books,biographies,news,videos,audio texts,retracted publications,and corrections,1 178 019 CVD research literatures were further evaluated.518 058 literatures were indexed as"strongly correlated to CVD"using Fuwai Subject Headings.Besides papers,other data sources were also collected,including 11 143 CVD-related Natural Science Foundation Projects,19 382 CVD-related effective authorized invention patents,103 CVD-related national prize achievements,24 CVD-related national research platforms,and 2 084 CDE registered data of CVD-related drug clinical trials.Research teams from nine sub-disciplines reviewed and validated research literature in respective fields,and classification rules of corresponding sub-disciplines were created and improved based on their opinions.Finally,eleven individual indexes were chosen to construct CAPE system for ranking global TOP100 medical institutions in overall CVD field and TOP30 in nine sub-disciplines.From 2016 to 2022,the number of cardiovascular disease research papers published by Chinese institutes has increased by 123.5%,with a total of approximately 76.8 thousands papers published(about 30 papers per day on average),ranked the second under the United States(approximately 114.1 thousands papers).However,the proportion of papers published by the Chinese Journal Citation Reports(JCR)and the Chinese Academy of Sciences only ranked eighth in the world.In the comprehensive academic performance of original cardiovascular research papers in global hospitals from 2020 to 2022,only two Chinese medical institutions ranked in the TOP20 as evaluated by CAPE system. Conclusions:Based on multi-source data from 2016 to 2022,CAPE initiated to establish a cardiovascular academic performance evaluation system.

Objective: To explore the feasibility of remotely obtaining complex information on traditional Chinese medicine (TCM) pulse conditions through voice signals. Methods: We used multi-label pulse conditions as the entry point and modeled and analyzed TCM pulse diagnosis by combining voice analysis and machine learning. Audio features were extracted from voice recordings in the TCM pulse condition dataset. The obtained features were combined with information from tongue and facial diagnoses. A multi-label pulse condition voice classification DNN model was built using 10-fold cross-validation, and the modeling methods were validated using publicly available datasets. Results: The analysis showed that the proposed method achieved an accuracy of 92.59% on the public dataset. The accuracies of the three single-label pulse manifestation models in the test set were 94.27%, 96.35%, and 95.39%. The absolute accuracy of the multi-label model was 92.74%. Conclusion Voice data analysis may serve as a remote adjunct to the TCM diagnostic method for pulse condition assessment.

Objective To predict and analyze the potential suitable areas of the Guangxi characteristic medicinal plant Zanthoxylum nitidum(Roxb.)DC.in China under climate change;To provide reference for ecological conservation and artificial cultivation of Zanthoxylum nitidum(Roxb.)DC.Methods Based on the 49 pieces of geographical distribution information of Zanthoxylum nitidum(Roxb.)DC.in China,19 environmental factors,and the maximum entropy(MaxEnt)model,a species distribution model was constructed to predict and analyze the potential growth areas of Zanthoxylum nitidum(Roxb.)DC.under current and future climate change.Results Under the current climate change,the potential suitable areas of Zanthoxylum nitidum(Roxb.)DC.in China mainly depended on 4 environmental factors:precipitation in the coldest season(Bio19),precipitation in the warmest season(Bio18),precipitation in the driest season(Bio17),and average annual temperature(Bio1).Under the future climate change,the center of mass of the high suitable areas of Zanthoxylum nitidum(Roxb.)DC.will mainly migrate to the northeast and northwest,and the migration distance will range from 13.63 km to 153.95 km.Compared with the present,the stable and unchanged high suitable areas of Zanthoxylum nitidum(Roxb.)DC.under future climate change will be reduced to about 21.68%,and mainly distributed in southwest Guangxi,and these stable and unchanged areas will become the first choice for semi-artificial planting of Zanthoxylum nitidum(Roxb.)DC.Conclusion The results are helpful to provide scientific basis for formulating reasonable ecological conservation and artificial cultivation strategies to reduce the impact of climate change on the population spread of Zanthoxylum nitidum(Roxb.)DC.

OBJECTIVE: A prospective randomized controlled study was conducted to investigate the early postoperative analgesic effectiveness of using liposomal bupivacaine (LB) for local infiltration anesthesia (LIA) in unicompartmental knee arthroplasty (UKA). METHODS: Between January 2024 and July 2024, a total of 80 patients with knee osteoarthritis (KOA) who met the selection criteria were enrolled in the study. Patients were randomly assigned to either the LB group or the "cocktail" group in a 1∶1 ratio using a random number table, with 40 patients in each group. Baseline characteristics, including gender, age, body mass index, operated side, Kellgren-Lawrence grade, and preoperative American Society of Anesthesiologists (ASA) classification, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee joint range of motion, showed no significant difference between the two groups ( P>0.05). Both groups received LIA and comprehensive pain management. The surgical duration, incision length, pain-related indicators [resting and activity visual analogue scale (VAS) scores, total dosage of oral morphine, WOMAC scores], knee joint range of motion, first ambulation time after operation, length of hospital stay, and postoperative adverse events. RESULTS: There was no significant difference between the two groups in surgical duration, incision length, first ambulation time after operation, length of hospital stay, total dosage of oral morphine, and pre-discharge satisfaction with surgery and WOMAC scores ( P>0.05). At 4, 12, and 24 hours after operation, the resting and activity VAS scores in the "cocktail" group were lower than those in the LB group; at 60 and 72 hours postoperatively, the resting VAS scores in the LB group were lower than those in the "cocktail" group, with the activity VAS scores also being lower at 60 hours; all showing significant differences ( P<0.05). There was no significant difference in the above indicators between the two groups at other time points ( P>0.05). On the second postoperative day, the sleep scores of the LB group were significantly higher than those of the "cocktail" group ( P<0.05), while there was no significant difference in sleep scores on the day of surgery and the first postoperative day ( P>0.05). Additionally, the incidence of complications showed no significant difference between the two groups ( P>0.05). CONCLUSION The use of LB for LIA in UKA can provide prolonged postoperative pain relief; however, it does not demonstrate a significant advantage over the "cocktail" method in terms of short-term analgesic effects or reducing opioid consumption and early functional recovery after UKA. Nevertheless, LB may help reduce postoperative sleep disturbances, making it a recommended option for UKA patients with cardiovascular diseases and insomnia or other mental health issues.
