BackgroundCompared with adult-onset schizophrenia， patients with adolescent-onset schizophrenia experience a high genetic susceptibility， severe negative symptoms， high recurrence rate， poor prognosis and social function recovery. And clarifying the brain functional alterations in adolescent-onset schizophrenia is of great significance for further elucidating the pathogenesis of the disease and exploring personalized and precise treatment. ObjectiveTo investigate the altered functional and effective connectivity of bilateral precuneus in first-episode patients with adolescent-onset schizophrenia based on resting-state functional magnetic resonance imaging （rs-fMRI）， thus providing reliable imaging evidence in guiding the study on mechanism involved in adolescent-onset schizophrenia. MethodsTwenty-one drugnaïve first-episode patients with adolescent-onset schizophrenia who met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） criteria for schizophrenia were enrolled， and another 21 psychiatrially healthy controls matched on age， educational background and gender were concurrently selected. The schizophrenic subjects were evaluated using the Psychotic Symptom Rating Scales （PSYRATS） and Positive and Negative Symptom Scale （PANSS）. All participants underwent rs-fMRI scans， and the whole-brain seed-based functional and effective connectivity analyses were conducted in bilateral cuneus region. Then the correlation between functional connectivity strength and clinical symptoms of patients was discussed. ResultsIn terms of functional connectivity， the functional connectivity of bilateral precuneus and left middle temporal gyrus was increased in patient group compared with healthy control group ［P<0.01， family-wise error （FWE） correction at cluster level， P<0.05］. In terms of effective connectivity， patient group responded to negative feedback with greater activation of seed region and left middle frontal gyrus than healthy control group. Correlation analysis within patient group denoted that the decreased effective connectivity of bilateral precuneus and left middle frontal gyrus was positively correlated with the total PANSS score （r=0.450， P<0.05）. ConclusionThe resting-state functional and effective connectivity of bilateral precuneus is abnormally alerted in drugnaïve first-episode patients with adolescent-onset schizophrenia， and the decreased effective connectivity of bilateral precuneus and left middle frontal gyrus may be related to the development of clinical symptoms. ［Funded by National Key Research and Development Program of China （number， 2022YFC2009901， 2022YFC2009900）］

MORPHOLOGICAL CHANGES OF RABBIT BLASTOCYSTS AT PREIMPLANTATION STAGE / 解剖学报

Ultrastructural changes of the inner cell mass (ICM) in rabbit blastocysts from 4 to 7 days post coitum (p.c.) were observed with transmission electron microscope. It revealed that ICM of blastocyst on day 5 p.c. began to differentiate after they were arranged into a single layer, and under which the primitive endoderm appeared. It is suggested that the primitive endodermal cells in rabbit blastocysts are derived from the scattered ICM-like cells at the inner surface of the mural trophoblast rather than delaminated from ICM proper. In this paper, disruption and disappearance of polar trophoblast are described and discussed.
