Objective:To explore the correlation between attempted suicide and childhood trauma as well as inflammatory cytokines levels in adolescents with depressive disorder.Methods:From January to December 2021, a total of 164 adolescents with depressive disorder were included and categorized into attempted suicide group ( n=108) and non-attempted suicide group ( n=56) according to whether they accompanied attempted suicide or not. The Chinese version of the suicide module of MINI 5.0, the childhood trauma questionnaire(CTQ), and the center for epidemiological studies depression scale (CES-D) were used to assess suicidal behavior, childhood trauma and depressive symptoms, while the plasma inflammatory cytokines levels were measured by electrochemiluminescence technology. The data were statistically analyzed by SPSS 23.0 software. Logistic regression was applied to analyze the independent influencing factors of attempted suicide and the predictive value of each independent risk factor for attempted suicide was assessed by receiver operating characteristic curve(ROC) curves. Results:The prevalence of attempted suicide was 65.9%(108/164) in adolescents with depressive disorder.The univariate analyses showed that the total CTQ score ((55.19±12.44), (45.50±12.11)) ( t=-4.771, P<0.001), CES-D total score ((40.75±10.26), (32.98±13.39)) ( t=-4.131, P<0.001), IL-6 level(1.87 (1.32, 2.69) pg/mL, 1.56 (1.05, 1.87) pg/mL)( Z=-3.102, P=0.002), IL-10 level (0.53 (0.38, 0.83) pg/mL, 0.47 (0.31, 0.69) pg/mL) ( Z=-2.100, P=0.036) and IL-17A level (2.20 (1.52, 3.65) pg/mL, 1.67 (1.25, 2.97) pg/mL) ( Z=-2.254, P=0.024) in plasma of patients in the attempted suicide group were significantly higher than those in non-attempted suicide group. Logistic stepwise regression analyses showed that CTQ total score, IL-6, IL-10, and IL-17A were risk factors for attempted suicide in adolescents with depressive disorder.The ROC showed that the total score of CTQ combined with IL-6 (AUC=0.782, 95% CI=0.709-0.855, P<0.001), the total score of CTQ combined with IL-10 (AUC=0.765, 95% CI=0.688-0.841, P<0.001), and the total score of CTQ combined with IL-17A (AUC=0.762, 95% CI=0.684-0.840, P<0.001) had a larger area under the curve, indicating better recognition and prediction ability for attempted suicide, with high sensitivity and specificity. Conclusion:The incidence of attempted suicide in adolescents with depressive disorder is high, and which is closely related to childhood trauma and the levels of inflammatory cytokines.

As a first-line classical drug, glucocorticoids are used in most combination treatment regimens of keloid. However, there are issues such as poor treatment efficacy and recurrence of keloid after keloid was treated with glucocorticoids, which seriously affect the therapeutic effect. In recent years, many studies have explored the factors influencing the efficacy of glucocorticoids in treating keloid and the action mechanism of glucocorticoids from different perspectives. Based on this, this paper reviews the mechanism and the factors influencing the efficacy of glucocorticoids in treating keloid, and explores ways to improve the treatment efficacy of glucocorticoids, aiming to provide thoughts for improving glucocorticoid-related diagnostic and therapeutic strategies.

Objective: To explore the relationship between insulin resistance and plasma hypersensitive reactive protein (hs-CRP) in patients with chronic schizophrenia. Methods: A total of 247 inpatients with chronic schizophrenia (patient group) and 166 cases of normal individuals(control group) were enrolled.Their general demographic and clinical data were collected, fasting blood glucose, hs-CRP, c-peptide and insulin indexes were tested, and insulin resistance index (HOMA-IR) was calculated.The insulin resistance level of the patients group and the control group was compared by Mann-Whitney U test, and the relationship between insulin-resistance and hs-CRP in patients group was analyzed using Spearman correlation analysis. Results: (1)The levels of C-peptide (2.53(2.06, 3.23)ng/ml vs 2.24(1.89, 2.87)ng/ml), insulin (7.68(4.66, 11.97)μIU/ml vs 7.02(4.31, 9.59)μIU/ml) and HOMA-IR (1.75(1.09, 3.07) vs 1.57(0.97, 2.22)) in the patient group were significantly higher than those in the control group(all P<0.05). (2) The levels of HOMA-IR( 1.91(1.21, 3.74) vs 1.70(1.02, 2.72)) in patients with high hs-CRP(≥3 mg/L) was higher than those in the patients with low hs-CRP(<3 mg/L)(P<0.05). (3)Spearman correlation analysis showed that HOMA-IR was positively correlated with plasma hs-CRP level in the patient group (r=0.139, P<0.05). (4)After logarithmic transformation of related variables, multivariate linear regression analysis showed that HOMA-IR was linearly correlated with hs-CRP level and boy weight index. Conclusion The hs-CRP level in chronic schizophrenia has a positive predictive effect on insulin resistance.Detection of hs-CRP level in schizophrenic patients is helpful to assess metabolic risk of insulin.
