Purpose: In this study, the neural communication patterns between hypothalamic structures and cortical areas in girls diagnosed with central precocious puberty (CPP) were explored. Endocrine profiles were incorporated to clarify the pathophysiological interactions between cerebral networks and hormonal regulation. The hypothalamus was designated as the key focus area for connectivity analysis. Methods: Fifty-seven girls (37 CPP, 20 non-CPP) were recruited from the Pediatric Development Clinic at the Second Affiliated Hospital of Anhui Medical University. The collected data included demographic information, gonadotropin-releasing hormone stimulation tests, and magnetic resonance imaging scans. Hypothalamic functional connectivity (FC) was analyzed using predefined region of interest coordinates, and correlations between hormone levels and FC values were assessed. Results: Compared to the non-CPP group, the CPP group exhibited elevated baseline follicle-stimulating hormone (FSH), baseline luteinizing hormone (LH), peak FSH, peak LH, and peak LH/FSH ratios. Patients with CPP exhibited enhanced neural synchronization linking the right lateral hypothalamic effector zone to the right superior frontal gyrus (displaying a borderline significant correlation with peak LH concentrations), concurrent with diminished functional coupling of the right lateral hypothalamic efferent to the right fusiform/supramarginal gyri. The left lateral hypothalamic projections demonstrated amplified connectivity with the right cuneus. No FC differences were observed in the medial hypothalamus. Conclusion Abnormal lateral hypothalamus FC patterns were identified in CPP girls and were particularly linked to peak LH levels. The findings offer novel insights into the neuroendocrine mechanisms underlying CPP.

ObjectiveTo compare the differences in thyroid hormone levels between adolescents with and without suicidal ideation， and to explore the association between thyroid hormone/suicidal ideation and the antidepressant treatment. MethodsA total of 100 patients were divided into non-suicidal ideation group and suicidal ideation group according to the SIOSS. The levels of thyroid-stimulating hormone （TSH）， triiodothyronine （T3）， thyroxine （T4）， free triiodothyronine （FT3） and free thyroxine （FT4） were compared between the two groups as well as their changes after 6 weeks of antidepressant treatment. ResultsThe levels of FT3， FT4 and T4 in the non-suicidal ideation group were higher than those in the suicidal ideation group. After 6 weeks of antidepressant treatment， the levels of FT3， FT4 and T4 in the suicide ideation group were higher than those before the treatment. The FT3 level in the male non-suicidal ideation group was higher than that in the suicidal ideation group. The levels of FT4 and T4 in the female non-suicidal ideation group were higher than those in the suicidal ideation group （all P<0.05） ConclusionThere are differences in thyroid hormone levels between adolescents with and without suicidal ideation （both with first-episode depression）， and patients with suicidal ideation have significant changes after treatment with antidepressants.

Objective:To explore the chain mediating effect of emotion dysregulation and trait anger between childhood trauma and aggressive behavior in adolescents.Methods:A sample of 1 333 undergraduates were recruited to complete the questionnaires about childhood trauma, aggressive behavior, emotion dysregulation, trait anger.The SPSS 23. 0 and Mplus 8.3 software were used to analysis data and test intermediate effect.Results:The scores of childhood trauma, aggressive behavior, difficulties in emotion regulation and trait anger were (33.624±8.211), (53.995±12.307), (91.781±17.518), (23.352±5.477), respectively. Correlation analysis showed that childhood trauma, aggressive behavior, emotion dysregulation and trait anger were positively correlated with each other( r=0.209-0.614; all P<0.01). Mediation modeling analysis showed that childhood trauma had a significant direct effect on aggressive behavior. The direct effect value was 0.121, accounting for 35.8% of the total effect. The total indirect effect of childhood trauma on aggressive behavior was 0.217, accounting for 64.2% of the total effect. The mediating effect of emotion dysregulation as mediator between childhood trauma and aggressive behavior was 0.035, accounting for 10.4% of the total effect. The mediating effect of trait anger as mediator between childhood trauma and aggressive behavior was 0.108, accounting for 31.9% of the total effect. The chain mediating effect of emotion dysregulation and trait anger was 0.074, accounting for 21.9% of the total effect. Conclusion:Emotion dysregulation and trait anger exert a multiple mediating effect on the relationship between childhood trauma and aggressive behavior.

Objective:To observe the effect of different concentration of Qianggubao decoction extract on proliferation of osteoblastic cells cultured by high glucose in vitro. Methods: osteoblastic cells was isolated from the skull of 1-2 day newly born SD rats by means of Trypsin-collagenase digestion and identified by image analysis,V-G collagen staining,ALP staining, calcification nod staining etc. Different concentrations of Qianggubao decoction extract were added to the osteoblastic cells cultured by high glucose in vitro(final concentration:300mg/dl)and incubuted.The effects of Qianggubao decoction extract on the proliferation of osteoblasts was monitored by MTT analysis. Results:Qianggubao extract of 100, 50, 10?g/ml all promoted for osteoblastic cell proliferation, the 100?g/ml and 50?g/ml had the better effects (P
