OBJECTIVES: To explore the molecular mechanism by which lncRNA SNHG15 regulates proliferation, invasion and migration of lung adenocarcinoma cells. METHODS: The lncRNA microarray chip dataset GSE196584 and LncBase were used to predict the lncRNAs that interact with miR-30b-3p, and their association with patient prognosis were investigated using online databases, after which lncRNA nucleolar RNA host gene 15 (SNHG15) was selected for further analysis. The subcellular localization of lncRNA SNHG15 and its expression levels in normal human lung epithelial cells and lung adenocarcinoma cell lines were detected using fluorescence in situ hybridization and qRT-PCR. In cultured A549 cells, the changes in cell proliferation, migration, and invasion following transfection with a SNHG15 knockdown plasmid (sh-SNHG15), a miR-30b-3p inhibitor, or their co-transfection were assessed with EdU, wound healing, and Transwell assays. Bioinformatics analyses were used to predict the regulatory relationship between lncRNA SNHG15 and COX6B1, and the results were verified using Western blotting and rescue experiments in A549 cells transfected with sh-SNHG15, a COX6B1-overexpressing plasmid, or both. RESULTS: LncRNA SNHG15 was shown to target miR-30b-3p, and the former was highly expressed in lung adenocarcinoma, and associated with a poor patient prognosis. LncRNA SNHG15 was localized in the cytoplasm and expressed at higher levels in A549 and NCI-H1299 cells than in BEAS-2B cells. In A549 cells, lncRNA SNHG15 knockdown significantly inhibited cell migration, invasion and proliferation, and these changes were reversed by miR-30b-3p inhibitor. A regulatory relationship was found between lncRNA SNHG15 and COX6B1, and their expression levels were positively correlated (r=0.128, P=0.003). MiR-30b-3p knockdown obviously decreased COX6B1 expression in A549 cells, and COX6B1 overexpression rescued the cells from the inhibitory effects of lncRNA-SNHG15 knockdown. CONCLUSIONS LncRNA SNHG15 may compete with COX6B1 to bind miR-30b-3p through a ceRNA mechanism to affect proliferation, migration, and invasion of lung adenocarcinoma cells.

OBJECTIVES: To elucidate the anti-aging effect of β-sitosterol (BS), an important component in the fruits of Alpinia oxyphylla Miq., in C. elegans and its regulatory effect on ETS-5 gene to modulate ferroptosis. METHODS: C. elegans treated with 10 µg/mL BS were monitored for survival time and changes in body length, motility, and reproductive function. The effect of ETS-5 gene knockdown on survival time of C. elegans was observed, and the changes in fat accumulation and lipid redox homeostasis in the transfected C. elegans were assessed using Oil Red O staining and by detecting MDA levels and the GSH/GSSG ratio. The mRNA expression levels of ferroptosis-related genes (FTN-1, GPX-1 and AAT-9) were detected using qPCR. The effects of BS treatment and ETS-5 knockdown on AAT-9 enzyme activity in C. elegans were examined. The effect of BS on nuclear localization of FEV (the human homolog of ETS-5) was validated in cultured human umbilical venous endothelial cells (HUVECs). RESULTS: Both BS treatment and ETS-5 knockdown significantly prolonged the lifespan, promoted lipid accumulation and reduced lipid peroxidation in C. elegans. ETS-5 knockdown resulted in upregulated expressions of the ferroptosis repressors GPX-1, AAT-9 and FTN-1 and increased the GSH/GSSG ratio in C. elegans. CONCLUSIONS BS inhibits ferroptosis in C. elegans by suppressing the expression of ETS-5 transcription factor and hence the activity of AAT-9 enzyme, a key gene for ferroptosis, which in turn prolongs the lifespan of C. elegans.

Objective To investigate the longitudinal relationship between sleep duration(SD)and positive youth development(PYD)among primary and secondary school students in Chengdu city using a cross-lagged model,and to provide scientific evidence for enhancing sleep management practices for students.Methods A total of 4061 students of grades 3 through 9 from the Chengdu Child Positive Development Cohort were included in this three-wave longitudinal study.There was a one-year interval between one survey and the following round of survey,and the time points for the baseline,12-month follow-up,and 24-month follow-up surveys were designated T0,T1,and T2.The PYD of the participants was assessed using the Chinese version of the Positive Youth Development Scale.The demographic data and the average daily SD over the past month were collected.Spearman correlation analysis was performed to examine the associations between SD and PYD,and a cross-lagged model was used to investigate the longitudinal relationship between them.Results The average daily SD for the 3 rounds of surveys conducted at T0,T1,and T2 was 9.00(8.04,10.00)hours,10.44(9.67,11.11)hours,and 10.39(9.83,11.00)hours,respectively,while the PYD scores were 5.30(4.73,5.71),5.27(4.73,5.73),and 5.39(4.89,5.77),respectively.Statistical significance was found in the differences of SD and PYD scores across the 3 rounds(P＜0.05).Spearman correlation analysis revealed synchronous correlations between SD and PYD at all three time points(r=0.10 at T0,r=0.18 at T1,and r=0.21 at T2,P＜0.05)and significant lagged correlations(e.g.,r=0.10 for T1-PYD and T2-SD,and likewise,significant correlation was found for the 3 other cross-lagged paths).The cross-lagged model demonstrated that PYD at T0 and T1 positively predicted SD at T1 and T2,respectively(β0-1=0.116[95％CI,0.083-0.150],β1-2=0.097(95％CI,0.067-0.127),P＜0.05),and that SD at T0 and T1 also positively predicted PYD at T1 and T2(β0-1=0.028[95％CI,0-0.056],β1-2=0.042[95％CI,0.010-0.074],P＜0.05).According to these findings,a bidirectional predictive relationship between SD and PYD across different time points was observed in primary and secondary school students.Furthermore,PYD demonstrated better performance for predicting SD than SD did for PYD.Subgroup analysis by sex confirmed the robustness of the predictive power of PYD for SD.Conclusion This study reveals a positive bidirectional predictive relationship between SD and PYD among primary and secondary school students,suggesting that higher levels of PYD may contribute to adequate sleep.These findings provide critical scientific evidence for schools and families to strengthen sleep management and promote the holistic development and well-being of adolescents.

Objective:To investigate the efficacy of a domestically developed small esophageal cooling device in implementing targeted temperature management (TTM) after resuscitation and its impact on organ injury using a porcine model of cardiac arrest and resuscitation.Methods:Thirty healthy male domestic white pigs were randomly divided into four groups using a random number table: sham (S group, n=6), normothermia (NT group, n=8), surface cooling (SC group, n=8), and esophageal cooling (EC group, n=8). The S group underwent only surgical preparation, while the other groups were subjected to 12 minutes of ventricular fibrillation followed by 6 minutes of cardiopulmonary resuscitation to establish cardiac arrest. The S and NT groups maintained a core temperature of (37.5±0.5)°C using a surface blanket. In the SC and EC groups, therapeutic hypothermia was induced post-resuscitation via surface blanket or esophageal cooling catheter to achieve a target temperature of 34°C, maintained the target temperature (34±0.5)°C for 6 hours, followed by controlled rewarming at 0.5°C/h to 37°C. Core temperature was continuously monitored for 12 hours post-resuscitation. Hemodynamic parameters, including stroke volume (SV), global ejection fraction (GEF), extravascular lung water index (ELWI), and pulmonary vascular permeability index (PVPI), were assessed using pulse indicator continuous cardiac output (PiCCO) monitoring. Serum levels of cardiac troponin I (cTnI), neuron-specific enolase (NSE), creatinine (Cr), and intestinal fatty acid-binding protein (IFABP) were measured via ELISA at 2, 6, 12, and 24 hours post-resuscitation. Neurological outcomes were evaluated at 24 hours using the neurological deficit score (NDS) and cerebral performance category (CPC). Continuous variables were analyzed using one-way ANOVA. Results:During TTM, the EC group exhibited a faster cooling rate [(1.52±0.18)°C/h vs. (0.94±0.32)°C/h, P<0.05] and shorter time to target temperature [(2.32±0.43) h vs. (3.78±0.82) h, P<0.05] compared to the SC group, with comparable maintenance and rewarming ( P>0.05). Compared to the S group, the NT, SC, and EC groups demonstrated significant post-resuscitation multi-organ injury, characterized by reduced SV and GEF, elevated ELWI and PVPI, and increased serum cTnI, NSE, Cr, IFABP, NDS, and CPC scores (all P<0.05). Relative to the NT group, the SC and EC groups showed improved SV (at 1 h post-resuscitation), GEF (at 1, 2, 4, and 6 h), ELWI (at 12 h), and reduced cTnI and NSE (at 6 h), Cr and IFABP (at 2 h), and NDS and CPC (at 24 h) (all P<0.05). Compared to the SC group, the EC group exhibited lower PVPI (at 12 h), reduced cTnI, Cr, and IFABP (at 2 h), decreased NSE (at 2, 12, and 24 h), and improved NDS (at 24 h) (all P<0.05). Conclusions:In a porcine model of cardiac arrest and resuscitation, the domestic esophageal cooling device facilitated rapid induction, stable maintenance, and controlled rewarming during TTM, outperforming traditional surface cooling. This approach demonstrated superior organ protection, warranting further investigation.

Objective To investigate the mechanism of iron death induced by TRPC6/NF-κB in glomerular podiocytes mediated by high homocysteine(Hcy).Methods Mouse glomerulopocytes were cultured in vitro and divided into Control group(0 μmol/L Hcy)and Hcy group(80 μmol/L Hcy).After 48h of intervention,Western blot was used to detect the expression levels of iron death related proteins GPX4 and SLC7A11 and TRPC6 and NF-κ B.Real-time quantitative fluorescence PCR(qRT-PCR)and immunofluorescence were used to detect the expression of TRPC6.The level of podocyte apoptosis was detected by flow cytometry.Malondialdehyde(MDA)assay kit was used to determine intracellular MDA levels.After transfection of TRPC6 interference fragment and TRPC6 negative control(NC),qRT-PCR was divided into Control,si-NC and si-TRPC6(Si-TRPC6-1,Si-TRPC6-2,Si-TRPC6-3).Western Blot was divided into Control,Hcy,si-NC+Hcy,si-TRPC6+Hcy.The expression of TRPC6 mRNA was detected by qRT-PCR.The expression levels of GPX4,SLC7A11,NF-κB and TRPC6 were detected by Western Blot.The level of podocyte apoptosis after interference was detected by flow cytometry.Results(1)Compared with Control group,the expression levels of iron death related proteins GPX4 and SLC7A11 in Hcy group were decreased,and the apoptosis rate was increased(P<0.05).(2)Compared with Control group,TRPC6 protein,mRNA levels and immunofluorescence expression were increased in Hcy group.The level of MDA and the expression of NF-κB signaling pathway protein increased in Hcy group,and the comparison between the two groups had statistical significance(P<0.05).(3)Compared with the si-NC group,the mRNA expression level of TRPC6 in si-TRPC6(Si-TRPC6-1,Si-TRPC6-2,Si-TRPC6-3)group was decreased,and the interference effect of Si-TRPC6-3 was the best(P<0.05).After transfecting TRPC6 NC and TRPC6 interference fragment and administering Hcy,there was no difference in GPX4,SLC7A11,NF-κB and TRPC6 expression in si-NC+Hcy group compared with Hcy group.Compared with the si-NC+Hcy group,the si-TRPC6+Hcy group had higher expression of iron death related proteins,GPX4 and SLC7A11,lower expression of NF-κB and TRPC6,and decreased apoptosis rate(P<0.05).Conclusion This study confirmed that TRPC6/NF-κB can regulate iron death of renal podocytes under the induc-tion of Hcy,which is one of the mechanisms leading to kidney injury.

ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula （温肾益心方加减， MWYF） as an auxiliary treatment of coronary heart disease （CHD） complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group （67 cases） and experimental group （68 cases） according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine， while the treatment group was additionally given MWYF， 1 dose per day； both groups were treated for 8 weeks. The traditional Chinese medicine （TCM） syndrome scores， angina scores， SF-36 scores， thyroid function indicators including thyroid stimulating hormone （TSH）， thyroxine （T4） and triiodothyronine （T3）， as well as serum cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， monocyte chemoattractant ligand 2 （CCL2）， and tumor necrosis factor-related activator protein （CD40L） levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated， and the safety was assessed. ResultsBias was adjusted by matching on propensity score， and 102 cases were finally included in the statistical analysis， with 51 cases in each group. The total effective rate regarding TCM syndrome ［94.12% （48/51） versus 64.71% （33/51）］， the total effective rate regarding angina pectoris ［80.39% （41/51） versus 62.75% （32/51）］， and the reduction and discontinuation rate of thyroid hormone preparation ［39.21% （20/51） versus 5.88% （3/51）］ were significantly higher in the experimental group than those in the control group （P＜0.05 or P＜0.01）. After treatment， the total TCM syndrome score， individual scores of major symptoms ， the major symptoms score， the secondary symptoms score， angina pectoris score， and TSH level were significantly reduced （P＜0.01）， while all dimensions of SF-36 scores， T4， T3， and cAMP levels significantly increased in both groups （P＜0.05 or P＜0.01）. The dosage of thyroid hormone preparations and the levels of cGMP， CCL2， and CD40L in the experimental group significantly decreased after treatment （P＜0.01）. When compared between the two groups after treatment， the total TCM syndrome score， the major symptoms score， the scores of individual major symptom （chest tightness， chest pain， fear of cold， cold limbs， waist and kness soreness and weakness）， the secondary symptoms score， angina pectoris score， TSH， cGMP， CCL2， and CD40L levels of the experimental group were significantly lower than those of the control group （P＜0.05 or P＜0.01）， while all dimension scores of SF-36， T4， T3， and cAMP levels were significantly higher （P＜0.01）. A total of three adverse events occurred during treatment， none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome， angina pectoris， quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency， and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance， the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.

Background Obsessive-compulsive personality disorder and obsessive-compulsive disorder(OCD)are common psychological disorders with similar clinical symptoms,but the differences between the two need further clarification.Objective To explore the clinical features of and influencing factors of obsessive-compulsive personality disorder in patients with OCD,so as to provide references for further relevant clinical diagnosis and treatment.Methods A total of 195 patients with OCD were selected as the research subjects,who received treatment at the outpatient and inpatient departments of the Affiliated Brain Hospital of Nanjing Medical University from July 2022 to December 2023 and met the diagnostic criteria for OCD in the International Classification of Diseases,tenth edition(ICD-10).Evaluation was conducted by using the Yale-Brown Obsessive Compulsive Scale(Y-BOCS),Personality Diagnostic Questionnaire-4+(PDQ-4+),Obsessive-Compulsive Inventory-Revised(OCI-R),Beck Depression Inventory(BDI),Beck Anxiety Inventory(BAI)and Sheehan Disability Scale(SDS).In accordance with the score of Obsessive-Compulsive Personality Disorder Scale in PDQ-4+,patients were divided into the OCD group with obsessive-compulsive personality disorder(n=58)and the OCD group without obsessive-compulsive personality disorder(n=137).Pearson correlation analysis and Spearman correlation analysis were adopted to examine the correlation between clinical features and the score of the Obsessive-Compulsive Personality Disorder Scale.Multiple linear regression analysis was used to explore the influencing factors of OCD patients with obsessive-compulsive personality disorder.Results Statistically significant differences were observed between OCD patients with and without obsessive-compulsive personality disorder in the age,family history of mental illness,time without treatment,hoarding and ranking dimension scores in OCI-R,OCI-R total score,score of Obsessive-Compulsive Personality Disorder Scale in PDQ-4,and BDI score(P≤0.05).OCD patients with obsessive-compulsive personality disorder in the time without treatment,OCI-R total score,hoarding and ranking dimension scores in OCI-R and BDI score are all positively correlated with the score of the Obsessive-Compulsive Personality Disorder Scale(r=0.120,0.526,0.364,0.492,0.414,P<0.05).The results of multiple linear regression analysis showed that time without treatment(β=0.132,P<0.05),hoarding dimension score(β=0.283,P<0.05)and ranking dimension score in OCI-R(β=0.418,P<0.05)were the influencing factors of OCD patients with obsessive-compulsive personality disorder.Conclusion OCD patients with obsessive-compulsive personality disorder may have longer untreated periods,more pronounced functional impairments in hoarding and sorting and more severe depressive symptoms.Untreated time,hoarding symptoms and sorting symptoms may be influencing factors for OCD patients with obsessive-compulsive personality disorder.

Objective:This study aimed to compare the audiological characteristics between children with unilateral auditory neuropathy (UAN) and single-sided deafness (SSD) to establish a valid basis for the differential diagnosis of children with UAN.Methods:A retrospective analysis was conducted on audiological and imaging evaluations of children with UAN and SSD who were treated at Beijing Children′s Hospital of Capital Medical University between May 2015 and June 2023. There were 17 children with UAN, comprising 10 males and 7 females, with an average age of 4.7 years. Additionally, there were 43 children with SSD, consisting of 27 males and 16 females, with an average age of 6.5 years. Audiological assessments included Auditory brainstem response (ABR), Steady-state auditory evoked potential (ASSR), Behavioural audiometry, Cochlear microphonic potential (CM), Distortino-product otoacoustic emission (DPOAE), and acoustic immittance test. The results of the audiological assessment and imaging phenotypic between the two groups of children were compared and analyzed by applying SPSS 27.0 statistical software.Results:(1) The UAN group (77.8%) had a significantly higher rate of ABR wave III L than the SSD group (20.9%) ( P<0.01). The PA thresholds at 500 Hz and 1 000 Hz of children with SSD were higher than those of children with UAN, while the ASSR thresholds at 500 Hz, 1000 Hz, 2 000 Hz, and 4 000 Hz of children with SSD were significantly higher than those of children with UAN ( P<0.05). (2) The degree of hearing loss in both UAN and SSD children was predominantly complete hearing loss. The percentage of complete hearing loss was significantly higher (χ2=4.353, P=0.037) in the SSD group (93.0%, 40/43) than in the UAN group (63.6%, 7/11). However, the percentage of profound hearing loss was significantly higher in the UAN group (27.3%, 3/11) than in the SSD group (2.3%, 1/43) ( Fisher′s exact test, P=0.023). In terms of hearing curve configuration, the percentage of flat type was significantly higher in the SSD group (76.7%, 33/43) than in the UAN group (36.4%, 4/11). The proportion of the UAN group (27.3%, 3/11) was significantly higher than that in the SSD group (2.3%, 1/43) in ascending type ( P<0.05). There were no statistically significant differences in the hearing curves of the declining type and other types between the two groups ( P>0.05). (3) The proportion of imaging assessment without abnormality was significantly more common in the UAN group (81.8%) than in the SSD group (37.1%) (χ2=6.695, P=0.015). Conclusions:Compared to children with SSD, the occurrence of wave III L on the ABR test was significantly more common in children with UAN. The percentage of ascending hearing curves was significantly higher in children with UAN than in children with SSD. ASSR thresholds were significantly lower in children with UAN. The normal imaging phenotype was significantly more common in children with UAN than in children with SSD.

In recent years, studies have shown that transplanted neural stem cells (NSCs) help neural tissues regenerate and return to normal through paracrine action rather than just replacing cells. Exosomes are essential paracrine mediators that can participate in cell communication through substance transmission. This review focuses on NSCs regulated by exosomes and their application in treatment of nervous system diseases, in order to provide important references for further research and clinical application of NSCs exosomes..
