OBJECTIVE: To elucidate the modulation mechanism of Suanzaoren Decoction (SZRD) on basolateral amygdala (BLA) neuronal activity to alleviate chronic restraint stress (CRS)-related behavioral deficits. METHODS: The male C57BL/6J mice were assigned to 4 groups using the complete randomization method, including control (CON, n=19), CRS (n=19), SZRD (n=21), and fluoxetine (Flu, n=22) groups. Mice were restrained for 6 h per day, over a 21-d period to establish CRS models. The CON group remained in their cages without food or water during the 6-h matching period. SZRD and Flu groups received intragastric administration of SZRD (4.68 g/kg) and Flu (20 mg/kg) daily, respectively, 30 min before restraint for 21 consecutive days. The therapeutic effects of SZRD were evaluated using behavioral tests including the tail suspension test, elevated plus maze test, and forced swimming test. The cellular Fletcher B. Judson murine osteosarcoma proto-oncogene (c-Fos) expression in the BLA was measured using immunofluorescence, while action potential (AP) firing and synaptic transmission in BLA pyramidal neurons were evaluated using whole-cell patch-clamp recordings. RESULTS: SZRD administration significantly increased time spent in the open arms and open-arm entries while reducing immobility time (P<0.05 or P<0.01). It downregulated CRS-induced c-Fos expression and AP firing of pyramidal neurons in the BLA (P<0.01). Additionally, SZRD selectively attenuated excitatory (P<0.01), but not inhibitory, synaptic transmission onto BLA pyramidal neurons. CONCLUSION SZRD alleviated CRS-induced anxiety- and depression-like behaviors in mice by modulating the excitability and synaptic transmission of BLA pyramidal neurons.

Objective To investigate the effects of transcutaneous auricular vagus nerve stimula-tion(taVNS)on preoperative anxiety and sleep quality in patients undergoing laparoscopic myomecto-my.Methods A total of 106 patients scheduled for elective laparoscopic myomectomy were randomly divided into active stimulation group(a-taVNS group,n=53)and sham stimulation group(s-taVNS group,n=53).Trait Anxiety Inventory(TAI)scores,State Anxiety Inventory(SAI)scores,Hos-pital Anxiety and Depression Scale-anxiety(HADS-A)scores,Amsterdam Preoperative Anxiety and Information Scale-anxiety(APAISa)scores,Athens Insomnia Scale(AIS)scores,hemodynamic parameters,and adverse reactions were evaluated before intervention(T0),30 min after interven-tion(T1),and the next morning(T2).The degrees of anxiety improvement(△SAI=SAIT0-SAIT1;△HADS-A=HADS-AT0-HADS-AT1;△APAISa=APAISaT0-APAISaT1)and sleep improvement(△AIS=AIST0-AIST2)were calculated,and their correlations were assessed.Results At T0,there were no significant differences in SAI,HADS-A,and APAISa scores between the two groups(P=0.376,0.682,0.144).At T1,there were significant differences in SAI and HADS-A scores between the two groups(adjusted P＜0.05),while there was no significant difference in APAISa scores(P=0.141).Compared with the s-taVNS group,the a-taVNS group had higher improvement values of △SAI,△HADS-A,and △APAISa(P＜0.001).Compared with T0,the AIS score de-creased and the incidence of sleep disorders decreased at T2 in the a-taVNS group(P＜0.05).Compared with the s-taVNS group,the AIS score and the proportion of patients with sleep disorders decreased at T2 in the a-taVNS group(P＜0.05).There was a positive correlation between the de-gree of anxiety improvement and the degree of sleep improvement in the a-taVNS group(P＜0.05),while there was no significant correlation in the s-taVNS group(P＞0.05).Compared with T0,sys-tolic blood pressure,diastolic blood pressure,and heart rate decreased at T1 in both groups,but there were no significant differences in these parameters between the two groups(P＞0.05).During the study period,no adverse events such as tinnitus,dizziness,headache,nausea,vomiting,or fa-cial flushing occurred in either group.Conclusion The method taVNS can improve preoperative anxiety and reduce the incidence of sleep disorders in patients undergoing laparoscopic myomectomy.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration. METHOD: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded. RESULTS: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations. CONCLUSION The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.

Objective:To explore the regulation of eight weeks aerobic exercise on brain spontaneous activity in individuals with subthreshold depression.Methods:Through subject recruitment, a total of 44 subjects with subthreshold depression (subthreshold depression group, StD) who scored≥5 according to Patient Health Questionnare-9 (PHQ-9) but did not meet the diagnostic criteria for clinical depression, and 34 healthy subjects (health control group, HC) were included. Two groups of participants were given 8-week moderate-intensity aerobic exercise intervention, and resting state functional magnetic resonance imaging (rs-fMRI) data were collected before and after the intervention to analyze the fractional amplitude of low frequency fluctuations (fALFF) in the two groups. Horizontal two-sample t-tests with years of education as a covariate and longitudinal paired-samples t-tests were performed for fALFF in both groups at baseline and after 8-week moderate-intensity aerobic exercise intervention. The relationship between the fALFF values in significant difference brain regions and psycho-psychological scales were examined by Spearman correlation. Results:After 8 weeks of moderate intensity aerobic exercise, the scores of PHQ-9 and Self-Rating Anxiety Scale (SAS) in StD were significantly lower than baseline ( t=7.08,5.99, both P<0.001). There was no significant difference in fALFF value between StD and HC at baseline. After aerobic exercise intervention, compared with the HC, the fALFF value of the left parahippocampal gyrus in the StD was significantly decreased, and the fALFF value of the left superior frontal gyrus and left precentral gyrus was significantly increased. After aerobic exercise intervention, compared with the baseline, the StD had significantly higher fALFF values in the left inferior parietal lobe (supramarginal gyrus and angular gyrus), right supramarginal gyrus and left anterior cingulate gyrus. In addition, compared with the baseline, the fALFF value of the right precentral gyrus in the HC was significantly decreased. After aerobic exercise intervention, the fALFF value of the left inferior parietal lobe was negatively correlated with the SAS scores ( r= -0.31, P=0.038), the fALFF value of the left anterior cingulate gyrus and the PHQ-9 item 2 (low mood) scores was negatively correlated ( r= -0.41, P=0.006), and the fALFF values of the left inferior parietal lobe, right supramarginal gyrus and the PHQ-9 item 6 (low self-evaluation) scores were negative correlated ( r=-0.39, P=0.010; r=-0.30, P=0.048). Conclusion:Eight weeks of moderate-intensity aerobic exercise can regulate the spontaneous activity pattern of local brain regions in individuals with subthreshold depression, and fALFF analysis can provide objective evidence for the antidepressant effect of aerobic exercise.

OBJECTIVE: To explore the effect of UVRAG on mitophagy in leukemia cells K562. METHODS: K562 cells were induced with different concentrations of mitophagy inducer carbonylcyanide-m-chlorophenylhydrazone (CCCP) for 6, 12 and 24 hours, and the cell viability was detected by the CCK-8 assay. K562 cells were divided into NC, UVRAG-siRNA, UVRAG-siRNA+CCCP, and CCCP group, while Western blot was used to detect the expression of UVRAG protein. Flow cytometry was used to detect the changes in reactive oxygen species (ROS) and mitochondrial structural integrity. The expressions of autophagy related proteins P62 and LC3-Ⅱ/LC3-Ⅰ were detected by Western blot. RESULTS: Compared with NC group, the expression of UVRAG protein in UVRAG -siRNA group significantly decreased (P<0.01). Compared with CCCP group, in UVRAG -siRNA+CCCP group ROS, mitochondrial structure damage, and the expression of LC3-Ⅱ/LC3-Ⅰ decreased significantly (P<0.05, P<0.05, P<0.01), while the expression of P62 protein increased (P<0.05). Compared with NC group, the differences in the expressions of P62 and LC3-Ⅱ/LC3-Ⅰ protein, ROS, and mitochondrial structural integrity in UVRAG -siRNA group were not obvious (P>0.05). CONCLUSION Under the treatment of CCCP, silencing UVRAG can inhibit mitophagy in K562 cells.
