The expression of autophagy-related proteins in peripheral blood mononuclear cells of patients with lupus nephritis is upregulated and related to kidney damage / 细胞与分子免疫学杂志

Objective To identify the relationship between nephritis activity, autophagy and inflammation in patients with SLE. Methods Western blot analysis was used to detect the expression of microtubule-associated protein 1 light chain 3 (LC3) and P62 in peripheral blood mononuclear cells (PBMCs) of SLE patients with lupus nephritis and non-lupus nephritis patients. Tumor necrosis factor α (TNF-α) and interferon γ (IFN-γ) in the serum of SLE patients were determined by ELISA. The correlation between LC3II/LC3I ratio and SLE disease activity score (SLEDAI), urinary protein, TNF-α and IFN-γ levels was analyzed by Pearson method. Results The expression of LC3 was increased and P62 was decreased in SLE patients. TNF-α and IFN-γ were increased in the serum of SLE patients. LC3II/LC3I ratio was positively correlated with SLEDAI (r=0.4560), 24 hour urine protein (r=0.3753), IFN-γ (r=0.5685), but had no correlation with TNF-α (r=0.04 683). Conclusion Autophagy is found in PBMCs of SLE, and the autophagy is correlated with renal damage and inflammation in patients with lupus nephritis.

Analysis on the use of antidepressants in inpatients with depression from 2015 to 2019 / 四川精神卫生

ObjectiveTo investigate the use of antidepressants in hospitalized patients with depression disorder from 2015 to 2019， and to analyze the changes of these antidepressants and medication regimens， so as to provide references for clinical drug use. MethodsUsing the Beijing-Tianjin-Hebei big data platform， the data of patients with depression in Beijing Anding Hospital， Capital Medical University from 2015 to 2019 were retrospectively analyzed. The changes of different types of drugs and medication regimens were described. ResultsFrom 2015 to 2019， a total of 6 043 cases of eligible patients were enrolled in analysis. Among selective serotonin reuptake inhibitors （SSRIs）， the prescription proportion of sertraline， citalopram and fluoxetine showed a trend of decline （P<0.05 or 0.01）， while the prescription proportion of escitalopram showed a trend of fluctuations （P=0.031）. In serotonin noradrenaline reuptake inhibitors （SNRIs）， the prescription proportion of duloxetine and milnacipran were rising （P<0.01）. The newer antidepressants agomelatine （P=0.001） and voltioxetine （P<0.01） also showed an upward trend. In terms of medication regimen， the proportion of single antidepressants and combined use of two antidepressants showed a downward trend （P<0.01）， while the proportion of antidepressants combined with mood stabilizers， antidepressants combined with mood stabilizers or antipsychotics showed an upward trend （P<0.05 or 0.01）. ConclusionIn the 5 years， the proportion of SSRIs decreased， and the proportion of SNRIs and newer antidepressants increased in hospitalized patients with depression. The proportion of antidepressants combined with mood stabilizers and antipsychotics in treatment regimens showed an increasing trend.

Research of exogenous HMGB1 regulate autophagy in peripheral blood monon-uclear cells of systemic lupus erythematosus / 中国免疫学杂志

Objective:To stimulate the PBMCs of systemic lupus erythematosus patients with recombinant human high mobility group box1 (HMGB1) protein,observe the effect of HMGB1 on the expression of LC3Ⅱ/Ⅰ protein in active lupus nephritis and inactive lupus nephritis patients.Evaluate the effect of recombinant human high mobility group box 1 ( HMGB1 ) on the proliferation of PBMCs in patients with SLE.Methods:Western blot was used to detect the expression of LC 3II/I protein in PBMCs of active lupus ne-phritis and inactive lupus nephritis patients after stimulated by 1 μg/ml HMGB1 for 0,6,24 and 48 h.CCK-8 assay was used to detect the effects of PBMCs proliferation in patients with SLE after 1 μg/ml HMGB1 stimulation 72 hours.The statistical software SPSS17.0 was used to analyzed the results.Results: Western bolt showed an increasing expression of LC 3Ⅱ/Ⅰ protein in SLE patients after stimulated by HMGB1 ( P<0.05 ) , and this effect was time dependent.Compared with inactive lupus nephritis group , the increasing level of autophagy in active lupus nephritis group was more obviously.1 μg/ml HMGB1 could inhibit the proliferation of PBMCs in patients of SLE significantly ( P<0.001 ).Conclusion: HMGB1 may promote autophagy in SLE especially patients with active lupus nephritis and involved in the pathogenesis of SLE and lupus nephritis.Monoclonal antibodies targeting to HMGB 1 or modulators of mam-malian autophagy may provide new way for the treatment of SLE especially LN.
