Coriolis加速度刺激对心理品质特殊飞行能力检查的影响（摘要）

目的观察Coriolis加速度刺激后对心理品质特殊飞行能力检查的影响。方法采用转椅方法对实验对象进行Coriolis加速度刺激。采用空军招飞系统统一配发的心理品质特殊飞行能力检测平台（二平台）进行心品特殊飞行能力检测,将系统仪器自动评出的分数为结果。将参加招收飞行学员体检的546名学生随机分为实验组和对照组,实验组转椅检查后立即进行心理品质特殊飞行能力检查;对照组转椅检查后24h以上进行心理品质特殊飞行能力检查。

Panniculitis–an unusual cutaneous manifestation of systemic sclerosis

Systemic sclerosis (SSc) is an autoimmune systemic disease characterized by small vessel involvement that leads to tissue ischemia and fibroblast stimulation resulting in accumulation of collagen (fibrosis) in the skin and internal organs. Lipomembranous panniculitis is a peculiar type of fat necrosis and has been reported with clinical conditions, commonly with peripheral vascular diseases. We describe a case of a 43‐year‐old woman with SSc manifestations, who presented with black scaly skin plaques, associated with thickening of the subcutaneous fat tissue, on the lateral surface of her thighs, her calves, gluteal area and lower abdomen. Biopsy revealed lipomembranous panniculitis. Lipomembranous changes have been seen in connective tissue disorders such as lupus profundus, morphea, systemic sclerosis and panniculitis associated with dermatomyositis, but rarely in thighs, calves, gluteal area and lower abdomen.

Transfusions to group O subjects of 2 units of red cells enzymatically converted from group B to group O

BACKGROUND: It has previously been shown that full-unit (200 mL) transfusions of red cells (RBCs) enzymatically converted from group B to group O by treatment with alpha-galactosidase (ECO RBCs) are both safe and efficacious for normal group O or A subjects. STUDY DESIGN AND METHODS: The present study describes the results of a comprehensive clinical and serologic assessment of 2-unit (400 mL) ECO RBC transfusions to each of four normal group O subjects (after each had donated 1 unit of whole blood). RESULTS: Clinical (hematologic tests, chemistry analysis, urinalysis) and serologic analyses revealed no evidence of immediate or delayed transfusion reaction, despite a threefold to fivefold elevation in pre-existing anti-B antiglobulin titer. 51Cr-labeled ECO RBCs were administered to one of the four subjects to allow direct measurement of ECO RBC survival in the circulation, which indicated that it was normal (24-hour survival, 95%; t1/2, 29.5 days). The observed increases in hemoglobin (by 1.3 +/− 0.4 g/dL [13 +/− 4 g/L]) and hematocrit (by 3.2 +/− 0.8% [0.032 +/− 0.008]) in transfused subjects provide further evidence of the efficacy of these cells in vivo. CONCLUSION: These results extend those observed in our earlier 1-unit transfusion studies and suggest that ECO RBCs pose little risk and will be useful in transfusion medicine.
