Coexistence of diffuse plane normolipaemic xanthoma and amyloidosis in a patient with monoclonal gammopathy

Diffuse plane normolipaemic xanthomatosis (DPNX) is a well-defined clinicopathological entity that characteristically presents with yellow–orange plaques in the periorbital areas, the neck, the upper trunk and the flexural folds. DPNX has been reported in association with lymphoproliferative disorders and, occasionally, with miscellaneous, probably coincidental disorders. A case of DPNX in a patient with an IgGλ monoclonal gammopathy and systemic amyloidosis is reported. Clinical and histopathological findings revealed typical features of DPNX and amyloidosis coexisting in the cutaneous lesions. To our knowledge this is the first reported case showing coexistence of xanthoma and amyloidosis in cutaneous lesions in a patient with a monoclonal gammopathy.     

Changes in causes of death among adults infected by HIV between 2000 and 2005: The "Mortalité 2000 and 2005" surveys (ANRS EN19 and Mortavic)

BACKGROUND: The multicenter national Mortalité 2005 survey aimed at describing the distribution of causes of death among HIV-infected adults in France in 2005 and its changes as compared with 2000. METHODS: Physicians involved in the management of HIV infection notified deaths and documented the causes using a standardized questionnaire similar to the previous survey performed in 2000. RESULTS: Overall, 1042 deaths were notified in 2005 (vs 964 in 2000): with median age, 46 years (vs 41 years); men, 76%; and median last CD4 cell count, 161/mm (vs 94). The proportion of underlying causes of death due to AIDS decreased (36% in 2005 vs 47% in 2000), and the proportion of cancer not related to AIDS or hepatitis (17% vs 11%), liver related disease (15% vs 13%: hepatitis C, 11%, and hepatitis B, 2%), cardiovascular disease (8% vs 7%), or suicide (5% vs 4%) increased. Among the 375 AIDS-related deaths, the most frequent event was non-Hodgkin lymphoma (28%). Among cancers not related to AIDS or hepatitis, the most frequent localizations were lung (31%) and digestive tract (14%). Among the 154 liver-related deaths, 24% were due to hepatocarcinoma. CONCLUSIONS: The heterogeneity of causes of death among HIV-infected adults was confirmed and intensified in 2005, with 3 causes following AIDS: cancers and liver-related and cardiovascular diseases.     

斩龙剑中新苯丙素甙的结构鉴定

从玄参科植物斩龙剑(Veronivastrum sibirica (L.)Pennell.)的根部分得九种化学成分,分别为斩龙剑甙A(sibiriosideA,Ⅰ)斩龙剑甙B(sibiriosideB,Ⅱ),异阿魏酸(isoferulicacid,Ⅲ),6-(4-methoxyferulpol)mioporoside(Ⅳ),scrophularioside(Ⅴ),6-O-阿魏酰梓醇(6-O-trans-feruloylcatalpol,Ⅵ),阿魏酸(ferulicacid,Ⅶ),胡萝卜甾醇(daucosterol,Ⅷ)和β-谷甾醇(Ⅸ)。其中斩龙剑甙A和斩龙剑甙B为新苯丙素甙化合物,应用波谱分析和理化数据测定,确定了它们的结构。     

中枢5—HT受体在电针对胃运动,胃电影响中的作用

目的：观察中枢５－ＨＴ２、５－ＨＴ３受体在电针对胃运动、胃电影响中的作用。方法实验采用霍耳效应原理慢性记录家兔胃运动的方法,同时记录胃电。观察家兔在自由进食和饮水后,清醒安静状态脑室注射赛庚啶、枢复宁条件下,电针“足三里”穴对胃运动和胃电慢波的影响。结果用赛庚啶阻断中枢５－ＨＴ２受体后,电针对胃运动及胃电的抑制效应大为减弱,而用枢复宁阻断中枢５－ＨＴ３受体后,对电针的抑制效应无明显影响。结论提示在
