Objective: To analyze the developmental trajectories of clustered health risk behaviors and their association with self-esteem and lonelinesss among junior high school students, so as to provide a reference for formulating comprehensive prevention and control measures of health risk behaviors among adolescents. Methods: In October 2023, 1 165 first year junior high school students from two schools of Jishou City in Hunan Province were selected by convenient sampling method for three follow up surveys (T1:October 2023; T2:April 2024; T3:October 2024). The Adolescent Health Risk Behavior Questionnaire, Rosenberg Self esteem Scale and Loneliness Scale were used to assess health risk behaviors, self esteem and loneliness, respectively. Latent growth curve modeling and latent growth mixture modeling were applied to analyze the developmental trajectories of clustered health risk behaviors among junior high school students. Logistic regression was used to analyze the association of the developmental trajectories of clustered health risk behaviors with self esteem and loneliness among junior high school students. Results: The overall developmental trajectories among junior high school students showed a declining trend (intercept=0.15, slope=-1.65, both P <0.05), with three heterogeneous categories:low risk improvement group ( n =862, 74.0%), moderate risk stable group ( n =260, 22.3%), and high risk deterioration group ( n =43, 3.7%). After adjusting the status of the left behind individuals，using the low risk improvement group as the reference category in multinomial Logistic regression analysis, results indicated that higher loneliness scores among junior high school students increased the risks of belonging to the moderate risk stable group ( OR=1.02, 95%CI =1.00- 1.04 ) and the high risk deterioration group ( OR=1.04, 95%CI =1.00-1.08), while higher self esteem scores reduced the risks of belonging to the moderate risk stable group ( OR=0.93, 95%CI =0.91-0.96) and the high risk deterioration group ( OR=0.88, 95%CI =0.83-0.94) (all P <0.05). Conclusions The overall trend of clustered health risk behaviors among junior high school students gradually improves, and the self esteem and loneliness are significant correlative factors. Targeted intervention measures should be developed for the junior high school students, with a focus on enhancing their self esteem and alleviating loneliness.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Objective:To investigate the effects of the Epley and Semont procedures with varying lateral angles of the head on posterior semicircular canal benign paroxysmal positional vertigo （PC-BPPV）. Methods:A total of 115 patients with unilateral PC-BPPV were randomly divided into five groups: Epley group, Semont group, Semont+10° group, Semont+20° group, and Semont+30° group, with 23 patients in each group. Corresponding reduction treatments were performed. Results:The total effective rates for the Epley group, Semont group, Semont+10° group, Semont+20° group, and Semont+30° group were 95.7% （22/23）, 4.3% （1/23）, 30.4% （7/23）, 52.2% （12/23）, and 87.0% （20/23） respectively. The inefficiencies were 4.3% （1/23）, 95.7% （22/23）, 69.6% （16/23）, 47.8% （11/23）, and 13.0% （3/23）. Statistically significant differences were observed in the total effective rates among the five groups （χ²=54.11, P<0.01）. The total effective rates in the Semont group, Semont+10° group, and Semont+20° group were significantly different from that of the Epley group （P<0.01）, while no statistically significant difference was found between the Semont+30° group and the Epley group （P= 0.608>0.012 5）. Conclusion:Among the four Semont methods with different lateral lying angles, the total effective rate of reduction treatment increased with the elevation of the lateral lying angle on the affected side. The efficacy of the Semont+30° group in treating PC-BPPV was not significantly different from the Epley group's reduction effect, which was markedly superior to that of the other four Semont methods at different angles. Therefore, the Semont+30° reduction technique is recommended for the treatment of PC-BPPV.

eIF3a is a N ⁶-methyladenosine (m⁶A) reader that regulates mRNA translation by recognizing m⁶A modifications of these mRNAs. It has been suggested that eIF3a may play an important role in regulating translation initiation via m⁶A during infection when canonical cap-dependent initiation is inhibited. However, the death of animal model studies impedes our understanding of the functional significance of eIF3a in immunity and regulation in vivo. In this study, we investigated the in vivo function of eIF3a using eIF3a knockout and knockdown mouse models and found that eIF3a deficiency resulted in splenic tissue structural disruption and multi-organ damage, which contributed to severe sepsis induced by Lipopolysaccharide (LPS). Ectopic eIF3a overexpression in the eIF3a knockdown mice rescued mice from LPS-induced severe sepsis. We further showed that eIF3a maintains a functional and healthy immune system by regulating B cell function and quantity through m⁶A modification of mRNAs. These findings unveil a novel mechanism underlying sepsis, implicating the pivotal role of B cells in this complex disease process regulated by eIF3a. Furthermore, eIF3a may be used to develop a potential strategy for treating sepsis.

Dendritic cells (DCs) serve as the primary antigen-presenting cells in autoimmune diseases, like rheumatoid arthritis (RA), and exhibit distinct signaling profiles due to antigenic diversity. Type II collagen (CII) has been recognized as an RA-specific antigen; however, little is known about CII-stimulated DCs, limiting the development of RA-specific therapeutic interventions. In this study, we show that CII-stimulated DCs display a preferential gene expression profile associated with migration, offering a new perspective for targeting DC migration in RA treatment. Then, saikosaponin D (SSD) was identified as a compound capable of blocking CII-induced DC migration and effectively ameliorating arthritis. Optineurin (OPTN) is further revealed as a potential SSD target, with Optn deletion impairing CII-pulsed DC migration without affecting maturation. Function analyses uncover that OPTN prevents the proteasomal transport and ubiquitin-dependent degradation of C-C chemokine receptor 7 (CCR7), a pivotal chemokine receptor in DC migration. Optn-deficient DCs exhibit reduced CCR7 expression, leading to slower migration in CII-surrounded environment, thus alleviating arthritis progression. Our findings underscore the significance of antigen-specific DC activation in RA and suggest OPTN is a crucial regulator of CII-specific DC migration. OPTN emerges as a promising drug target for RA, potentially offering significant value for the therapeutic management of RA.

Transcranial temporal interference stimulation (tTIS) is a novel non-invasive neuromodulation technique with the potential to precisely target deep brain structures. This study explores the neural and behavioral effects of tTIS on the superior colliculus (SC), a region involved in eye movement control, in mice. Computational modeling revealed that tTIS delivers more focused stimulation to the SC than traditional transcranial alternating current stimulation. In vivo experiments, including Ca²⁺ signal recordings and eye movement tracking, showed that tTIS effectively modulates SC neural activity and induces eye movements. A significant correlation was found between stimulation frequency and saccade frequency, suggesting direct tTIS-induced modulation of SC activity. These results demonstrate the precision of tTIS in targeting deep brain regions and regulating eye movements, highlighting its potential for neuroscientific research and therapeutic applications.

AIM:To investigate the effect of fenofibrate(FF)on the heart of rats with high-altitude heart dis-ease-induced right ventricular hypertrophy(H-RVH),and to explore the mechanisms and associated signaling pathways.METHODS:A total of 36 six-week-old male SD rats were randomly divided into control,model(H-RVH),and FF inter-vention(H-RVH+FF)groups with 12 rats each.A rat model of H-RVH was established by single subcutaneous injection of Sugen 5416(20 mg/kg)and exposure to a hypoxic condition(5 000 m above sea level)for 21 d in all groups except the control group.The rats in H-RVH+FF group were given FF(60 mg·kg-1·d-1)through gavage,while those in control and model groups received equal volume of saline once daily for 21 d.Rat heart gross morphology was observed,and the heart volume and weight,right ventricular weight and other hypertrophy indexes were measured in each group at the end of the experiment.A right heart floating catheter was used for measuring pulmonary artery and right ventricular pressure.Cardi-ac function was checked through cardiac ultrasonography.The serum levels of atrial natriuretic peptide(ANP),N-termi-nal pro-brain natriuretic peptide(NT-proBNP),free fatty acids(FFA),and myocardial tissue glucose(Glu)in all groups of rats were detected.The protein expression of peroxisome proliferator-activated receptor α(PPARα),fatty acid binding protein 1(FABP1),carnitine palmitoyl transferase 1a(CPT1a),pyruvate dehydrogenase kinase(PDK),and pyruvate dehydrogenase(PDH)were detected through Western blot.RESULTS:(1)Compared with the control group,the H-RVH group showed a significant increase in heart morphology and weight and increases in heart weight/body weight(HW/BW),heart volume,right ventricular weight/heart weight(RVW/HW),and Fulton index(FI)(P<0.05).Cardiac mor-phology,volume,heart weight,and HW/BW significantly decreased in the fenofibrate intervention group compared with the H-RVH group(P<0.05).RVW/HW and FI also decreased.(2)The right heart float catheter test showed that the mean right ventricular pressure(mRVP)and mean pulmonary artery pressure(mPAP)significantly increased in the H-RVH group compared with the control group(P<0.01).The increases in mRVP and mPAP were reversed in rats in the fe-nofibrate intervention group compared with the H-RVH group.(3)Cardiac ultrasonography showed that compared with the control group,the H-RVH group had significantly increased right ventricular anterior wall(RVAW)and right ventricular posterior wall(RVPW)thickness(P<0.01),significantly decreased right ventricular end-diastolic diameter(RVEDD),and right ventricular end-diastolic length(RVEDL)(P<0.01).In addition,pulmonary artery acceleration time(PAAT)was reduced,ejection time(PAET)was prolonged,and PAAT/PAET ratio decreased(P<0.01).Compared with the H-RVH group,the fenofibrate intervention group showed significant decreases in RVAW and RVPW(P<0.05),increases in RVEDD and RVEDL,and an increase in PAAT/PAET ratio.(4)The kit assay showed that the levels of ANP and NT-Pro BNP in serum were significantly higher in the H-RVH group than in the control group(P<0.05),while the levels of both were lower in the fenofibrate intervention group.The levels of serum FFA and myocardial tissue Glu levels(P<0.05)were significantly higher in the H-RVH group than in the control group.The levels of serum FFA and myocardial tissue Glu level were significantly lower in the fenofibrate intervention group than in the H-RVH group(P<0.05).(5)Western blot results showed that the expression levels of PPARα,FABP1,CPT1a,and PDH in the myocardial tissues of rats in the H-RVH group were significantly reduced(P<0.01),whereas the expression level of PDK significantly increased relative to those of the control group(P<0.01).All the effects on the above indices in the H-RVH group can be significantly re-versed by fenofibrate intervention(P<0.05).CONCLUSION:Fenofibrate exerts a protective effect on the hearts of rats with right ventricular hypertrophy associated with high-altitude heart disease by activating PPARα/FABP1/CPT1a,en-hancing fatty acid oxidation,inhibiting PDK,and activating PDH to promote the aerobic oxidation of glucose.Hence,the medication can ameliorate glucose-lipid metabolism disorders.
