Objective:To further investigate the safety and efficacy of Belimumab in the treatment of patients with systemic lupus erythematosus (SLE).Methods:All SLE patients treated with Belimumab from May 1, 2020 to February 1, 2022 in Peking Union Medical College Hospital were retrospectively collected and analyzed. The clinical manifestations, the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2000) score, and laboratory test such as levels of anti-dsDNA antibody, the medication before and after Belimumab treatment, adverse events were collected. Normally distributed data were tested using the t-test, otherwise the Wilcoxon paired signed rank test was used. Results:A total of 81 patients were enrolled in this study. The use of belimumab could significantly decrease the SLEDAI-2000 score [10.00(7.75, 12.00) vs. 4.00(3.75, 6.00), Z=-5.38, P<0.001], ESR of SLE patients [19.50(12.75, 32.25) mm/1 h vs. 14.00(7.75, 20.25) mm/1 h, Z=-3.71, P=0.003], anti-dsDNA titer detected by CLIFT [300.00 (117.00, 864.00) vs. 183.00(100.00, 471.00), Z=-4.15, P=0.001], meanwhile, increase the complement C3 [0.78 (0.62, 0.97)g/L vs. 0.69 (0.55, 0.84)g/L, Z=-4.68, P<0.001], and the complement C4 [0.12 (0.08, 0.19)g/L vs. 0.10 (0.05, 0.14)g/L, Z=-4.78, P<0.001]. We also observed that with the use of Belimumab, the dosage of Glucocorticoids decreased significantly, which were [10.00(7.50, 22.50) mg vs. 7.50(5.00, 10.00) mg, Z=-4.90, P<0.001]. In addition, the antibody of IgG, IgA and IgM decreased significantly. Only one patient stopped the administration of Belimumab due to the low level of immunoglobulin. Conclusion:Belimumab can alleviate disease activity of patients with SLE and help in safely tapering the daily dose of glucocorticoid with good safety.

Objective:To investigate the neurobiochemical metabolites of caudate nucleus and thalamus in patients with obsessive-compulsive disorder and their relationship with obsessive-compulsive symptoms.Methods:From April 2019 to January 2022 in Beijing Anding Hospital, totally 25 untreated patients with obsessive-compulsive disorder were recruited, and 20 healthy controls matched with gender, age and educational background were recruited for the study.The maps of neurobiochemical metabolites of patients and normal controls were collected by hydrogen proton magnetic resonance spectroscopy.With bilateral caudate nucleus and thalamus as brain regions of interest.The relative concentrations of N-acetylaspartic acid (NAA), glutamic acid (Glu) and γ-aminobutyric acid (GABA) were fitted by LCModel software.At the same time, the clinical symptoms of patients were evaluated with Yale-Brown obsessive-compulsive scale (Y-BOCS) and Hamilton anxiety scale (HAMA). SPSS 20.0 software was used for statistical analysis.Independent double sample t-test was used to compare the differences of different nerve biochemical metabolite concentrations between patients with obsessive-compulsive disorders and healthy controls.Pearson correlation analysis was used to explore the correlation between biochemical metabolite concentrations and clinical symptoms. Results:The Glu concentration in the left thalamus of patients with obsessive-compulsive disorder (3.97±0.41) was higher than that of the control group (3.66±0.55)( t=-2.11, P<0.05), while the NAA concentration was (4.87±0.47)lower than that of the control group (5.15±0.44)( t=2.05, P<0.05). The GABA concentrations in the right caudate nucleus (0.50±0.18) and thalamus (0.80±0.19) were lower than those in the control group ((0.63±0.23), (0.96±0.24))( t=2.08, 2.36, both P<0.05). Pearson correlation analysis showed that the Glu concentration in the left caudate nucleus of patients with obsessive-compulsive disorder was positively correlated with the total score of Y-BOCS( r=0.46, P<0.05). Spearman correlation analysis showed that Glu concentration in the right caudate nucleus was positively correlated with the total score of HAMA in patients with obsessive-compulsive disorder ( r=0.46, P<0.05). Conclusion:NAA, Glu and GABA metabolism in caudate nucleus and thalamus are abnormal in patients with obsessive-compulsive disorder, and Glu concentration is positively correlated with the severity of obsessive-compulsive and anxiety symptoms.

Objective To develop a simple,multi-dimensional self-screening questionnaire for som-atoform symptoms(SQSS). Methods Based on theoretical framework,the study developed the items of the questionnaire. The first draft of the questionnaire was screened through the expert evaluation method. Four groups of 359 subjects were selected to test the reliability and validity of questionnaire. Results The explor-atory factor analysis showed that the four factors(somatic symptoms,negative perception,illness behavior and social function) were extracted and the interpretable percentage of variance was 61. 165%. The correlation between the subscales and the total scales was 0. 740-0. 887,and the correlation coefficient between the sub-scales was 0. 503-0. 625. The Crobanch's α coefficient of the questionnaire was 0. 926,and the Spearman-Brown score of the questionnaire was 0. 868. The retest correlation coefficient of the total scale was 0. 876. A cutoff of 23 points in the SQSS was identified for screening somatoform disorders, and the sensitivity was 0. 880 and the specificity was 0. 606. Conclusion SQSS has good reliability and validity,and can be prelim-inarily used as a self-screening tool for patients with somatoform symptoms or disorders in clinical settings.

Objective To explore the detection rate and clinical characteristics of multiple somatic symptoms among adult outpatients in cardiology,neurology and GI clinics.Methods The general demographic data and disease-related information of 1 497 patients in Beijing Chaoyang Hospital,Beijing Anzhen Hospital and Beijing Tongren Hospital were collected through continuous inquiry and screening.Physical symptoms and depressive symptoms were assessed by Patient Health Questionnaire-15 (PHQ-15) and Patient Health Questionnaire-9 (PHQ-9).The patients were divided into multiple somatic symptoms group (SOM+group,PHQ-15≥10) and non-multiple somatic symptoms group (SOM-group,PHQ-15＜10).The detection rate of multiple somatic symptoms was calculated.Partial correlation analysis was used to analyze the correlation of PHQ-15 with the demographic,course of disease,cumulative number of visits,and the total score of PHQ-9.Results The overall detection rate of multiple somatic symptoms was 32.67％ (489/1 497)in the three hospitals,and the highest was found in the department of digestive medicine (37.74％,191/506).There were significant differences in gender (x2=36.85,P＜0.01),working status (x2=19.78,P＜0.01),visiting department (x2=9.64,P＜0.01),first visiting/repeated visiting (x2=6.67,P＜0.01),and the total score of PHQ-9 (x2=231.52,P＜0.01).The detection rate of female patients was higher than that of male patients.The detection rates of retired patients and patients who had no daily stable work were higher than patients who had daily stable work.The detection rate of re-visited patients was higher than that of first-visited patients.The illness duration (r=0.07,P＜0.05,Bonferroni correction) and the total score of PHQ-9 (r=0.66,P＜0.05,Bonferroni correction) were positively correlated with the severity of somatic symptoms measured by PHQ-15.Conclusions The detection rate of multiple somatic symptoms was high in general hospitals,especially highest in digestive outpatient clinics,and significantly higher in female,retired,unemployed,re-visited and patients who have depressive symptoms.Depressive symptoms and the illness duration were positively correlated with the severity of somatic symptoms.
