[Expert consensus on late stage of critical care management].

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

[Recommendations of diagnosis and treatment of Takayasu's arteritis in China].

Takayasu's arteritis (TAK) mainly involves the aorta and its major branches, which is characterized as a chronic, progressive and inflammatory disease. China belongs to one of the regions with a high prevalence of TAK referring to its global distribution. However, it is insufficient for the spread and update of standardized diagnosis and treatment of TAK. Based on the evidence and guidelines from China and other countries, Chinese Rheumatology Association developed the standardized diagnosis and treatment of TAK in China. The purpose is to standardize the methods for diagnosis of TAK, assessment of disease activity and disease severity, strategies of internal treatment and timing of surgical intervention, and further leading to protect the function of important organs and improve the disease prognosis.

[The analysis of clinical characteristics and disease activity in ankylosing spondylitis patients with hyperuircemia].

Objective: to investigate the clinical characteristics and disease activity in ankylosing spondylitis (AS) patients with hyperuricemia. Method: Laboratory tests, magnetic resonance imaging, disease activity and functional index of AS patients from Fudan University Zhongshan Hospital were collected. T test, square test were applied to investigate the difference between AS patients with hyperuricemia and AS patients with normal serum uric acid in clinical characteristics and disease activity in AS patients. Result: Among all the AS patients, 23.4% (22/94) patients accompanied with hyperuricemia. AS patients accompanied with hyperuricemia showed significant younger age (28.9±7.9 vs 35.8±11.1, P=0.002); higher serum alanine aminotransferase (33.6±23.6 vs 19.8±12.4, P=0.014), aspartate aminotransferase (23.8±8.7 vs 18.6±9.6, P=0.025) and creatinine (78.4±12.5 vs 69.8±13.3, P=0.009), lower Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) (11.2±8.8 vs 17.9±12.0, P=0.027) and Bath Ankylosing Spondylitis Functional Index (BASFI) (0.7±0.9 vs 1.8±2.2, P=0.002) compared with AS patients whose serum uric acid level is normal. Conclusion: AS Patients with younger age, impaired hepatic and renal funtion and lower scores in BASDAI and BASFI tend to accompany with hyperuricemia.

[A comparative study of diagnostic efficacy of different diagnostic/ classification criteria in Takayasu arteritis].

OBJECTIVE: This study aimed to analyze and evaluate the diagnostic efficacy of Ishikawa's, the modified Ishikawa's criteria, 1990 American College of Rheumatology (ACR ) classification criteria and the diagnostic model based on Chinese population in Chinese TA patients. METHODS: One hundred and forty-nine patients with Takayasu arteritis and 126 patients with other vascular disorders which involved aorta or its branches were recruited in this study.All the patients were admitted to the Department of rheumatism and Immunology clinic or inpatient department of Zhongshan Hospital affiliated to Fudan University from January 1(st), 2008 to June 31(st), 2015.General characteristics, clinical manifestations, laboratory results and imaging data of all the patients were collected.Sensitivity, specificity, accuracy and area under receiver operating characteristics (ROC) curve of different criteria were analyzed. RESULTS: Sensitivity, specificity, accuracy and area under ROC curve of Chinese diagnostic model were 90.60%, 80.95%, 86.18%, and 85.80%, respectively, while those of Ishikawa criteria were 34.23%, 99.21%, 64.00%, and 66.70%, respectively.These four indicators of the modified Ishikawa criteria were 84.13%, 79.87%, 81.82%, and 82.00%, respectively and that of ACR criteria were 83.89%, 83.33%, 83.64%, and 83.60%, respectively.No significant difference was found between any two of Chinese diagnostic model, the modified Ishikawa criteria and ACR criteria in all the indicators.Sensitivity of Chinese diagnostic model was highest, while specificity of Ishikawa criteria was the highest.Among these four criteria, the diagnostic efficacy of Chinese model was the best and that of Ishikawa criteria was the worst. CONCLUSION: Chinese diagnostic model, which is based on Chinese population and adopts advanced imaging modality, has better diagnostic efficacy.

Dopamine receptor DR2 expression in B cells is negatively correlated with disease activity in rheumatoid arthritis patients.

OBJECTIVE: Dopamine receptor (DR) signaling is involved in the pathogenesis of autoimmune diseases. We aimed to measure the expression levels of DR1-5 on B cells from patients with rheumatoid arthritis (RA) and to analyze the relationship between DRs and clinical manifestations, inflammatory biomarkers, functional status and disease activity. METHODS: A total of 29 patients with RA, 12 healthy donors and 12 patients with osteoarthritis (OA) were recruited in this study. Flow cytometry was used to measure the levels of DR1-5 expressed on B cells. The relationships between B cell DR expressions and clinical features in RA patients were analyzed using the Spearman correlation test. RESULTS: The expression levels of B cell DR1-5 in both the RA and OA groups were lower than those in healthy controls. After 3 months of medication, all five receptors were elevated in RA patients, with DR2 and DR3 being significantly increased from the baseline. DR2 expression on B cells was negatively correlated with inflammatory biomarkers and disease activity. CONCLUSION: RA patients had lower expression level of DR2 on B cells compared to the healthy controls, and the level of DR2 negatively correlated with the disease activity. DR2 and DR3 might be novel predictors of patient responses to disease modifying antirheumatic drug therapy.

[Effect of conventionally prepared rabbit serum on human umbilical vein endothelial cell-304].

OBJECTIVE: To study the effect of conventionally prepared rabbit serum, usually used in the field of serum pharmacology of TCM, in various concentration on cultured system of human umbilical vein endothelial cell (VEC)-304 cell line. METHODS: Prepared conventionally from healthy rabbit, the effect of uncontaminated and nonhemolytic serum of six concentrations (5%, 10%, 20%, 40%, 60% and 80%) on VEC-304 cells was observed using parameters such as cell morphologic examination, trypan blue exclusion test, methyl thiazolyl tetrazolium (MTT) test, lactate dehydrogenase (LDH) and angiotensin-converting release test. RESULTS: Serum of 5% and 10% concentration showed no effect in all the above-mentioned tests. Serum of 20% concentration also showed no effect in the tests except for LDH releasing (P < 0.01). But when the concentration of serum reached up to 40% or above, distinct cytotoxicity and serious injury appeared in a dose-dependent manner. CONCLUSION: High concentration of conventionally prepared rabbit serum could injure the incubated cell. Therefore, in order to lower the background effect of serum as far as possible in TCM serum pharmacological study, the cytotoxicity of rabbit serum should be tested first of all.
