中专内科学教学艺术

中专生年龄小，自我约束力差，文化基础薄弱，理解能力有限，以自我为中心。这些特点决定知识点繁杂。且相对枯燥的内科学教学要讲究艺术，才能激发学生学习兴趣，提高教学质量。     

香菇多糖联合抗生素治疗恶性肿瘤围化疗期肺部感染120例临床观察

目的：本文观察香菇多糖对恶性肿瘤患者围化疗期肺部感染抗生素治疗的增效作用。方法：120例围化疗期发生肺部感染恶性肿瘤患者在接受抗生素治疗的同时，随机分成加用香菇多糖针和不加香菇多糖针静脉滴注两组。每组各60例。结果：接受抗生素及香菇多糖联合治疗的患者的有效率显著提高（P〈0．05）．临床症状、体征与X光胸部片改善时间大幅缩短。结论：香菇多糖对恶性肿瘤患者围化疗期肺部感染抗生素治疗有明显增效作用。     

螺旋CT轴位扫描及重建对隐匿性骨折的临床应用价值研究

目的 探讨螺旋CT轴位扫描及重建（MPR、3D）在隐匿性骨折诊断中的临床价值。方法 选择34例隐匿性骨折患者，将螺旋CT薄层（2-5mm）扫描的容积数据转输至工作站进行MPR和3D处理，并对轴位、MPR和3D图像进行比较。结果 轴位在二维平面内清晰显示隐匿性骨折的基本情况，但MPR和3D能更好显示隐匿性骨折。MPR可以从任意平面和曲面观察隐匿性骨折及周围结构，3D能通过旋转和切割技术充分曝露病变，直观、逼真的显示隐匿性骨折立体关系。结论 螺旋CT对隐匿性骨折的诊断具有很高应用价值。MPR、3D及轴位图像的联合应用，为临床医师提供立体、直观、多方位的影像信息，有利于临床治疗方案的选择。     

儿童血友病429例临床回顾分析

目的探讨血友病患儿确诊时间、症状及其关节畸形等情况。 方法天津血液学研究所血液病医院于1986年7月至2004年8月，对就诊的429例血友病患儿临床症状出现时间、诊断时间及关节畸形出现的时间进行分析。 结果429例血友病患儿，均为男性，血友病A共390例，占909%，其中亚临床型5例(13%),轻型43例(110%)，中型181例(464%)，重型161例(413%)；血友病B共39例，占91%，其中亚临床型2例(51%),轻型6例(154%)，中型26例(667%)，重型5例(128%)。患儿初次出现出血症状的中位年龄为16岁(0~12岁)；但初次诊断年龄03~120岁，中位年龄为52岁(03~120岁)，两者之间差异具有显著性意义(P<001)。 结论目前血友病患儿的诊断存在延迟，替代治疗疗程和因子剂量的不足是关节畸形高发生率的原因。     

Vascular endothelial growth factor expressing mesenchymal stem cells improves cardiac function in chronic myocardial infarction in pigs

Transplantation of mesenchymal stem cells （MSCs） for myocardial reconstruction has shown promise in both animal models and human phase 1 clinical studies. Vascular endothelial growth factor （VEGF） is a strong therapeutic agent for treating ischaemia by inducing angiogenesis. The feasibility of ex vivo MSCs mediated gene transfer is documented. Matsumoto and colleagues have recently reported genetically engineered MSCs carrying VEGF165 delivery for revascularization in a model of acute myocardial infarction （MI）. The promising data from our laboratory in both angiogenesis and MSCs transplantation in cunicular heart model of acute MI have prompted us to attempt the combined and simultaneous application of the two strategies.     

Association between TGF-Beta1 in allograft and chronic allograft nephropathy]

OBJECTIVE: To investigate the relation between TGF-beta1 in allograft and chronic allograft nephropathy (CAN). METHODS: The levels of urine TGF-beta1 were tested in 146 recipients whose renal function were normal from September 1, 2000 to January 31, 2001. Twenty recipients with the highest level of urine TGF-beta1 were classified in group A, while 20 other recipients with the lowest level of urine TGF-beta1 were classified in group B. In these two groups biopsies were carried out in 14 cases and 12 cases respectively, and TGF-beta1 mRNA in the biopsies was measured by RT-PCR. The levels of TGF-beta1 in the blood were also measured in the two groups. Three years later, the renal function was compared between the two groups. Biopsies were carried out in renal recipients whose creatinine is higher than normal. RESULTS: The level of TGF-beta1 in the blood showed no significant difference between the two groups; 3 years after transplantation, the loss of renal function in group A was severer than that in group B. The number levels of CAN cases in group A was larger than that in group B. The expression levels of TGF-beta1 and TGF-beta1 mRNA of the allografts were higher in group A than in group B; there were statistically significant differences between the two groups. CONCLUSION: The findings suggest that there is an association between TGF-beta1 in kidneys and CAN. The level of urine TGF-beta1 after renal transplantation may predict future renal function.

Androgen receptor mutants detected in recurrent prostate cancer exhibit diverse functional characteristics

OBJECTIVE：Alterations in the function of androgen receptor （AR） and its signaling pathway may be responsible for the progression of prostate cancer. The goal of the present study was to investigate the potential roles of AR structural and functional alterations in the progression of prostate cancer, and the relationship between the structure and function of the AR.
