Résumé
Objective:To investigate the relationship between white blood cells, neutrophil-lymphocyte ratio(NLR), platelet-lymphocyte ratio(PLR) and monocyte-lymphocyte ratio(MLR) with patients suffering from first episode depression.Methods:This retrospective study was conducted among inpatients of Hebei General Hospital from January 2021 to December 2021.Ultimately, 193 patients with first-episode depression were enrolled.According to the score of Hamilton depression scale-24 (HAMD-24), the patients were divided into mild-moderate depression group(20≤HAMD-24<35 score, n=98) and severe depression group (HAMD-24 score ≥35, n=95). White blood cells and the counts of each cell subtype were detected and the NLR, MLR and PLR were calculated.SPSS 25.0 statistical software was used to analyze the data.Mann-Whitney U test was used to compare differences in the two groups and Binary Logistic regression analyses were performed to recognize the predictive factors of the severity of first episode depression. Results:(1) The white blood cells and NLR in the severe depression group were significantly higher than those in the mild-moderate depression group (white blood cells: 5.77(2.05)×10 9/L vs 5.11(1.31)×10 9/L; NLR: 1.86 (1.04) vs 1.57(0.55), P<0.05). There were no significant differences in PLR and MLR between the two groups ( P>0.05). (2)Multiple regression analysis of NLR, white blood cells and HAMD-24 score showed that there were significant differences in the effect of different white blood cells and NLR levels on HAMD-24 score( B=1.398, P=0.003; B=2.624, P=0.001). (3)Binary Logistic regression revealed that white blood cell count and NLR were risk factors for the severity of depression patients( OR were 1.612 and 2.336, respectively, P<0.05). Conclusion:The results suggest that white blood cells and NLR may be relate with the severity of first episode depression.

@# Objective To explore the effects of cognitive behavioral therapy and citalopram on regional cerebral blood flow(rCBF)in the patients with depression disorder.Methods 38 patients with depression disorder were divided into the cognitive behavioral therapy group(n=18),and citalopram group(n=20).The rCBF changes and scores of Hanmilton Depression Scale(HAMD)of all patients in two groups were evaluated with 99Tcm-ECD single photon emission computed tomography(SPECT)and HAMD before and after treatment.Results After treatment,the symptoms of all patients in two groups improved,but the cases of the citalopram group got a rapid improvement compared with those of the cognitive behavioral therapy group.Both of two methods could increase blood flow in right basal ganglion;while,the blood flow also increased in right limbic system in the cognitive behavioral therapy group,and in right temporol lobule in the citalopram group.Conclusion Both cognitive behavioral therapy and citalopram are effect on symptoms of depression disorder,but affect blood flow in different parts.

@#ObjectiveTo investigate the related functional orientation of the visual cognition antijamming ability in brain.MethodsThe number of recognizing errors of reaction to visual stimulations in 8 patients with brain lesions in conjunctions of occipital and parietal lobes was tested by three different kinds of noises from visual materials as stimulations, and error numbers as index, and result was compared with that of 10 normal persons.ResultsThe number of recognizing errors in the patients was higher than that in normal person ( P<0.01), and the signal-to-noise (SNR) lower, the number of recognizing errors was higher in the patients ( P<0.01).ConclusionThe conjunction of occipital and parietal lobes maybe play an important role in the visual cognition antijamming ability.
