RESUMO
Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.
RESUMO
Objective@#To explore the correlation between serum high density lipoprotein (HDL) levels and cognitive function in patients with bipolar disorder.@*Methods@#A total of 99 patients with bipolar disorder were enrolled from the inpatient of Suzhou Guangji Hospital.Serum HDL levels were measured by enzymatic colourimetry.Cognitive function was assessed by the repeatable battery for the assessment of neuropsychological status (RBANS). The relationship between serum high density lipoprotein and cognitive function was analyzed by correlation analysis and stepwise multiple regression analysis.@*Results@#Serum HDL levels ((1.39±0.55)mmol/L)were positively correlated with the RBANS total score (68.92±12.48)(r=0.238, P=0.034) and language score(80.59±15.97) (r=0.239, P=0.033) in patients with bipolar disorder.Stepwise multiple regression analysis showed that serum HDL level was the influencing factor of total score of RBANS(β=4.791, t=2.151, P=0.035)and speech function(β=7.363, t=2.247, P=0.027).@*Conclusion@#Serum HDL levels can influence cognitive function, especially speech function in patients with bipolar disorder.
RESUMO
Objective To explore the correlation between serum high density lipoprotein ( HDL) levels and cognitive function in patients with bipolar disorder. Methods A total of 99 patients with bipolar disorder were enrolled from the inpatient of Suzhou Guangji Hospital. Serum HDL levels were measured by enzymatic colourimetry. Cognitive function was assessed by the repeatable battery for the assessment of neuro-psychological status (RBANS). The relationship between serum high density lipoprotein and cognitive func-tion was analyzed by correlation analysis and stepwise multiple regression analysis. Results Serum HDL lev-els ((1. 39±0. 55) mmol/L) were positively correlated with the RBANS total score (68. 92 ± 12. 48) ( r=0. 238,P=0. 034) and language score(80. 59±15. 97) (r=0. 239,P=0. 033) in patients with bipolar disor-der. Stepwise multiple regression analysis showed that serum HDL level was the influencing factor of total score of RBANS(β=4. 791,t=2. 151,P=0. 035) and speech function(β=7. 363,t=2. 247,P=0. 027). Conclusion Serum HDL levels can influence cognitive function,especially speech function in patients with bipolar disorder.
