Influencing Factors of Prepulse Inhibition Deficit in Patients with Schizophrenia and Observations on the Efficacy of Traditional Chinese Medicine

This study aims to analyze the abnormal expression of lncRNAs in peripheral blood mononuclear cells (PBMCs) of patients with schizophrenia, investigate the influencing factors of prepulse inhibition deficit in patients and observe the efficacy of traditional Chinese medicine. A total of 106 patients with schizophrenia who underwent treatment at our hospital from January 2020 to December 2022 were included, along with 45 healthy individuals who received routine check-ups as control subjects. The significantly expressed lncRNAs were validated and analyzed using ROC curve analysis, and logistic regression analysis was used to identify the factors influencing prepulse inhibition deficit. Find 125 lncRNAs were found to be differentially expressed lncRNAs in the PBMCs of patients with schizophrenia, including 62 upregulated and 63 downregulated lncRNAs. And smoking amount, and relapse frequency were influencing factors for prepulse inhibition deficit in patients with schizophrenia. Animal experiments were conducted using hematoxylin eosin staining to observe the number and morphology of neurons in the hippocampal CA3 area and prefrontal cortex of rats, and the effects of natural Chinese medicine Poria cocos on the nervous system were analyzed. Find the acidic polysaccharides from Poria cocos, a natural traditional Chinese medicine, can promote the regeneration of neuronal cells, reduce excessive autophagy of neurons in the CA3 area of the hippocampus and prefrontal cortex of rats, promote neuronal cell proliferation, and improve neuronal cell morphology. Traditional Chinese medicine has good effects in psychopathology, positive and negative symptoms, and PANSS total score. Disruption of lncRNA expression may be one of the biological factors contributing to the pathogenesis of schizophrenia and is closely related to its mechanism. Prepulse inhibition, reflecting sensory gating function, is an important factor affecting perceptual and cognitive functions in patients with schizophrenia. Gender, smoking amount, and relapse frequency may influence prepulse inhibition deficit in these patients. Traditional Chinese medicine shows potential in improving prepulse inhibition deficit. The acidic polysaccharides from Poria cocos, a natural traditional Chinese medicine, can promote the regeneration of neuronal cells, effectively improve the damage to the structure and function of neurons in the hippocampal CA3 area and prefrontal cortex. When used in combination with other traditional Chinese medicines, it could offer new approaches for treating schizophrenia.
