Randomized Controlled Trial[Effects of intranasal dexmedetomidine for children undergoing dental rehabilitation under general anesthesia: a double-blinded randomized controlled trial].
To observe the preoperative sedation, the status of separation from parents, compliance with the mask, hemodynamic parameters and postoperative agitation of intranasal dexmedetomidine (DEX) premedication on children undergoing dental rehabilitation under general anesthesia. ⋯ Premedication with intranasal DEX 2 μg/kg for children undergoing dental rehabilitation under general anesthesia produces good preoperative sedation. The levels of sedation, scores of parental separation and compliance with the mask were satisfied. The children have good recovery conditions, and no obvious postoperative agitation and respiratory depression after DEX administration. Intranasal DEX 2 μg/kg is an effective and safe alternative for premedication in children.

[Comparison of disease activities and extent measurements for anti-neutrophil cytoplasmic autoantibody-associated vasculitis].
To investigate the significance of a set of seven disease activities and extension measurements and their correlations between one and another for anti-neutrophil cytoplasmic autoantibody associated vasculitis (AAV). ⋯ All of those seven AAV assessment indicators above can be used as indicators of disease activity and prognosis in AAV patients, most of which were relevant within one and another. There were high correlations among BVAS-2003, BVAS-1994 and BVAS/GPA, and besides, there were also high correlations between FFS-1996 and FFS-2009.

Systemic lupus erythematosus (SLE) is a highly heterogeneous autoimmune disease, characterized by production of pathogenic autoantibodies and wide involvement of multiple systems. Damageofimmune tolerance and imbalance of immune homeostasis lead to the production of autoantibodies and the injuries of multiple organs and systems. In recent years, plenty of studies have identified that immunometabolism affects survival status of certain cells, also cell activation, differentiation and effector functions. ⋯ Aggregated lipids rafts and increased synthesis of glycosphingolipid and cholesterol also have been observed in the CD4+ T cells from patients with SLE, leading to the abnormally elevated TCR signaling. Moreover, mechanistic target of rapamycin (mTOR) signaling is activated in the CD4+ T cells from both patients with SLE or mouse models of lupus and participate in the metabolic abnormalities of pathological CD4+ T cells. Progressive understanding of immunometabolism give us new insights of the pathogenesis of SLE and provide us with more therapeutic targets in the treatment of SLE.

Case Reports[Case series and clinical analysis of 14 cases of catastrophic antiphospholipid syndrome].
Catastrophic antiphospholipid syndrome (CAPS), also known as Asherson's syndrome, is a special subtype of antiphospholipid syndrome (APS) characterized by multiple intravascular thrombosis involving multiple organs systems or tissues simultaneously or continuously, high titer antiphospholipid antibodies and high mortality rate. This article's aims was to analyze the clinical manifestation, laboratory examination and treatment therapy of CAPS for the purpose of improving the understanding, diagnosis and treatment of the disease in clinical practice. ⋯ CAPS patients suffer from life-threatening acute multiple small vessel thrombosis with high titer of antiphospholipid antibody, potentially leading to multiple organ failure and a poor prognosis, thus early diagnosis and sufficient treatment are critical to prevent the progression of disease and improve the prognosis.

[Analysis of risk factors for acute lung injury/acute respiratory distress syndrome after esophagectomy].
To explore the incidence and risk factors for the acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) after resection of esophageal carcinoma. ⋯ ALI/ARDS was a serious complication in patients undergoing esophagectomy associated with increment in length of hospital stay and in-hospital mortality. Multivariate Logistic regression analysis indicated that preoperative FEV1/FVC, ASA classification and one lung ventilation duration were the independent risk factors for ALI/ARDS after esophagectomy. Carefully assessing the patient before operation, shortening one lung ventilation duration were the key points in preventing ALI/ARDS after esophagectomy.
