Objective To survey the function and relation of cytokine interleukin-6 (IL-6) between depression,anxiety and rheumatoid arthritis (RA).Methods One hundred and twenty-one patients with RA were investigated.All of them were assessed by Hamihon Depression Rating Scale and Hamihon Anxiety Rating Scale.Results ① The rate of depression in RA patients was 44.6％,and the rate of anxiety was 32.2％,the rate of depression combined anxiety in RA patients was 30.6％.② Social factors:Unemployment [14 cases (26.4％) vs8 cases (11.9％),x2=4.14] and education [41 cases (83.7％) vs 37 cases (58.7％),x2=8.11]was significantly different between depression and non-depression patients (P＜0.05).Age,unemployment and education was significantly different between anxiety patients and non-anxiety patients (P＜0.05).③ Clinical factors:tender joint count,swollen joint count,disease activity score (DAS)28,health assessment questionnaire (HAQ),VAS,function of joint and C-reactive protein (CRP) was significantly different between depression patients and non-depression patients [6(2,21) vs 1(0,14);4(1,11) vs 2(0,8);24.0(2.5,36.25) vs 2.5(0,19.5);5(3,9) vs 4(0,7);89.8％ vs 9.7％;37.63(13.25,70.75) vs 11.29(2.05,36.78)] (P＜0.05).And anxiety patients and non-anxiety patients had the same results [6(3,25) vs 2(0,14);6(1.5,12) vs 2(0,7.25);25(5,36) vs 3(0,25);8(5,10) vs 5(1.75,7);91.4％ vs 64.5％;33.4(11.0,63.0) vs 16.8(2.5,54.3)](P＜0.05).④ Cytokine:IL-6 was significantly different between depression patients and non-depression patients (P＜0.05).JAK-2,JAK-3,Signal transducer and activator of transcription (STAT)-3,matrix Metalloproteinases (MMP)-3,MMP-13 were not different between depression patients and non-depression patients (P＞0.05).IL-6,JAK-2,JAK-3,STAT-3,MMP-3,MMP-13 were not different between anxiety patients and non-anxiety patients (P＞0.05).⑤ Correlation analysis:Education level was negatively related with the severity of depression (r=0.288,P＜0.05).Tender joint count,swollen joint count,DAS28,HAQ,VAS,function of joint,erythrocyte sedimentation rate (ESR),CRP,IL-6 was positively related with the severity of depression (r=0.348,0.268,0.481,0.318,0.381,0.417,0.397,0.311,0.249;P＜0.05).Education level was negatively related with the severity of anxiety.Tender joint count,swollen joint count (r=-0.244,P＜0.05),DAS28,HAQ,VAS,function of joint,ESR,CRP was positively related with the severity of depression (r=0.282,0.261,0.381,0.284,0.284,0.299,0.263,0.178;all P＜0.05).⑥ Risk factors:IL-6 was the only risk factor in RA patients with depression.Conclusion The rate of depression and anxiety in RA is 44.6％.Depression and anxiety is related with disease activity,pain and HAQ.IL-6 is a high risk factor that makes patients prone to develop depression in RA patients.

Amyotrophic lateral sclerosis (ALS) is a relentless, progressive, and presently incurable neurodegenerative disease. Its drug development has been hampered by the lack of effective biomarkers for early diagnosis, progression and prognosis. Recently, significant progress has been made for the identification of body fluid biomarkers for ALS, which conferred both theoretical and practical feasibility for the early diagnosis and progression monitoring. Meanwhile, it also facilitated identification of genes and/or pathways for the pathogenesis of ALS. This review summarized biomarkers identified from cerebrospinal fluid, blood and urine of ALS patients and their clinical implications.

The incidence of augmented renal clearance (ARC) in intensive care patients (ICU) is exceptionally high, and these patients are often co-morbid with infection. The occurrence of ARC will significantly increase the clearance rate of antibiotics, making it difficult for conventional doses to reach effective therapeutic concentrations and affect the patient's anti-infective treatment effect and prognosis. It can be seen that it is crucial to formulate a reasonable dosing regimen for ICU patients with ARC. Regrettably, few reports in China about the adjustment strategy of antibiotic dosing regimens for ARC patients. Therefore, this article reviews the domestic and foreign literature for reference to provide evidence for medical personnel to adjust the dose of antibacterial drugs for such patients.
