ABSTRACT
Objective@#To explore the characteristics of blood lipid level and cognitive impairment in first-episode schizophrenic patients with positive and negative symptoms, and their correlation.@*Methods@#Seventy inpatients with first-episode schizophrenia were enrolled in the hospital.Their psychiatric symptoms were assessed by positive and negative syndrome scale (PANSS). They were divided into two groups positive symptoms group with 42 patients and negative symptoms group with 28 patients.All patients were assessed with the Chinese version of the measurement and treatment research to improve cognition in schizophrenia consensus cognitive battery (MCCB). The differences and characteristics of cognitive function between the two groups were compared.Body mass index (BMI), serum triglyceride, total cholesterol, low density lipoprotein and high density lipoprotein were recorded at admission, and the results were compared between the two groups.The correlation between cognitive assessment scores and metabolic indicators intra groups were analyzed using pearson correlation analysis.@*Results@#The scores of trail making test(TMT), brief assessment of cognition in schizophrenia-symbol encoding(BACS), Hopkins verbal learning test, maze and continuous performance test-identical pairs(CPT-IP) in positive group((27.13±6.89), (32.97±13.69), (35.70±7.52), (32.63±4.59), (33.35±11.10)) were higher than those in negative group ((12.90±14.72), (19.90±11.98), (25.80±5.44), (27.50±5.20), (19.89±11.29), all P<0.05). In terms of BMI and lipid metabolism indicators, the total cholesterol and low-density lipoprotein levels in the negative group ((5.03±1.42), (3.04±1.18)) were higher than those in the positive group ((4.18±0.78), (2.45±0.64)), and the difference was statistically significant (P<0.05). In negative group, total cholesterol and low density lipoprotein were negatively correlated with the scores of TMT(r=-0.469, -0.751), BACS(r=-0.517, -0.538) and CPT-IP(r=-0.495, -0.542) in cognitive function(all P<0.05).@*Conclusion@#First-episode schizophrenia patients with positive and negative symptoms have similar lesion dimensions in cognitive function, but patients with negative symptoms are more severely impaired.There are differences in lipid metabolism between first-episode schizophrenia patients with positive dominant symptoms and negative dominant symptoms, and the lipid metabolism of first-episode schizophrenia patients with negative dominant symptoms is related to cognitive function.
