异常黑胆质成熟剂对移植性宫颈癌(U27)肿瘤模型小鼠血清的代谢组学研究

目的 建立移植性宫颈癌(U27)肿瘤小鼠模型并探讨异常黑胆质成熟剂(Abnormal Savda Munziq,ASMq)对移植性宫颈癌(U27)肿瘤模型小鼠血清代谢的影响。方法 采用核磁共振氢谱(¹H-NMR)技术结合模式识别和正交偏最小二乘判别法(OPLS-DA)进行分析,寻求不同剂量的ASMq以及环磷酰胺(Cyclophosphamide,CY)给药干预后移植性宫颈癌(U27)肿瘤模型小鼠血清中代谢产物的变化以及发生改变的代谢网络途径。结果 与正常对照组比较,移植性宫颈癌(U27)肿瘤模型组小鼠血清中异亮氨酸、缬氨酸、丙氨酸、谷氨酰胺、甘氨酸等氨基酸及乳酸、柠檬酸、肌酸和1-甲基组氨酸等代谢物含量明显降低,而低密度脂蛋白(low density lipoprotein,LDL)含量升高,差异有统计学意义(P<0.05)。与移植性宫颈癌(U27)肿瘤模型组比较,环磷酰胺组中亮氨酸、丙氨酸等代谢物含量升高,差异有统计学意义(P<0.05)。与移植性宫颈癌(U27)肿瘤模型组比较,灌胃不同剂量ASMq之后小鼠血清中异亮氨酸、亮氨酸、缬氨酸、丙氨酸、谷氨酰胺等氨基酸含量升高及糖蛋白、柠檬酸、肌酸等代谢物含量也有升高趋势,差异有统计学意义(P<0.05)。结论 ASMq对移植性宫颈癌(U27)肿瘤模型小鼠有一定的抗肿瘤作用,其作用机制可能是不仅调节移植性宫颈癌(U27)肿瘤模型小鼠体内发生紊乱的氨基酸、能量代谢,也可以提高免疫功能,从而实现其预防与治疗肿瘤的作用。     

1996-2007年新疆阿图什市内脏利什曼病的流行概况

1996-2007年,阿图什市共报告内脏利什曼病102例,其中以阿湖乡(占37.3%)、阿扎克乡(27.5%)、松塔克乡(19.6%)和上阿图什乡(8.8%)为主,其余乡和市区呈散发状态。男女性别之比为1.04:1。0～5岁(占30.4%)和6～10岁(占29.4%)年龄组人群病例数最高,此后随年龄的增大病例数呈减少趋势。在近10年中,1998年发病数最高(占21.6%),2000年最低(1.0%)。阿图什市仍然是内脏利什曼病流行区,需采取有效控制措施。     

Immunological Marker Analysis of Mitogen-Induced Proliferating Lymphocytes Using Brd U Incorporation or Screening of Metaphases

The proliferative effects of the mitogens phytohaemagglutinin (PHA), concanavalin A (Con A), pokeweed mitogen (PWM), and staphylococcal protein A (SpA) were investigated using two different methods which enable immunological marker analysis of proliferating cells: either surface marker labelling followed by BrdU incorporation or screening of metaphases after surface marker labelling. Therefore peripheral blood mononuclear cells from six healthy volunteers were stimulated with these four mitogens. Both PHA and Con A gave rise to more CD8+ than CD4+ proliferating cells. PHA, but not Con A, induced B-cell proliferation as well. PWM mainly caused T-cell proliferation. SpA also appeared to be a potent T-cell mitogen in addition to its capacity to induce B-cell proliferation. However, in contrast to the other mitogens SpA predominantly stimulated CD4+ cells.     

PORTAL HYPERTENSION DUE TO ARTERIOVENOUS FISTULA OF THE GASTRODUODENAL ARTERY

The record is presented of a patient with severe recurrent bleeding due to portal hypertension. Surgical control of the feeding vessels of a fistulous communication between the gasHoduodenal artery and its companion vein arrested the haemorrhage and controlled the portal hypertension.
