三峡建坝对长江中下游江滩地区血吸虫病流行的可能影响

因兴建水库改变自然环境而加剧血吸虫病流行,国内外屡有报道。热带地区建设用于灌溉或其它目的的水库,已使水源性疾病流行区的感染程度大幅度上升,并形成了新的流行区。灌溉系统建设为钉螺孳生刨造了有利的环境条件。农业的发展使人口增加(包括移民迁入),从而使血吸虫病流行加剧。埃及的阿斯

原发型肝细胞癌动脉化疗栓塞术和全身静脉化疗的疗效比较及毒副反应观察

目的比较原发型肝细胞癌动脉化疗栓塞术和全身静脉化疗的疗效及毒副反应。方法58例中晚期原发型肝细胞癌患者根据接受治疗情况分为两组:动脉化疗栓塞组(动脉组)30例和全身静脉化疗组(静脉组)28例,两组所用的化疗药物相同。结果动脉组肿瘤缩小率、血清AFP下降率、生存率均优于静脉组(P<0.001,P<0.01)。不良反应发生率动脉组肝痛及发热均明显高于静脉组(P均<0.001),动脉组恶心呕吐、白细胞下降、ALT升高与静脉组比较均无显著性差异(P均>0.05)。结论动脉化疗栓塞术是中晚期肝癌安全、有效的治疗方法。     

抑郁发作自杀未遂患者脑源性神经营养因子水平及其相关因素研究

Objective To investigate the possible role of brain-derived neurotrophic factor(BDNF)in the pathophysiology of attempted suicide in depressive episode patients.Methods The subjects were 23 depressive episode patients who had recently attempted suicide.24 depressive episode patients without suicide attempt.and 30 sex-age-and education matched healthy controls.The Hamihon Depression Rating Scale-24 items(HAMD24),Beck Helpless Rating Scale(BHS)and Self-rating Idea of Suicide Scale (SIOSS)was used to evaluate the severitv of symptoms.The seruln level of BDNF was detected with sandwich ELISA.Pearson correlation coefficients wag used to measure the correlations between serum BDNF and the related illness variables.Results There were significant difierences in the serum level of BDNF between patients with attempted suicide,pailents without suicide attempt and normal controls(F=21.927,P＜0.05).Post hoc analysis showed the serum BDNF levels in patients with attempted suicide [(57 ±16)ng/L]were lower than that in patients without[(75±28)ns/L;P＜0.05],and were lower in patients without suicide attempt[(75 ±28)ng/L]than that in normal controls[(111 ±39)ng/L;P＜0.01].In patients with attempted suicide,the serum BDNF was negatively correlated to the duration of depressive episode(r=-0.541,P=0.008),the mean BHS score(r=-0.494,P=0.017)and the mean SIOSSscore(r=-0.754.P=0.000).Conclusion The results suggest that the decreased serum brain-derived neurotrophic factor is related to the pathophysiology of attempted suicide in depressive episode patients.     

创伤性肉毒中毒(颅脑损伤并发肉毒中毒的首例报告)

报告1例由于头皮撕裂伤感染肉毒杆菌引起的创伤性肉毒中毒,伤后11天出现全身无力、视物模糊、上睑下垂、咽下困难、呼吸肌麻痹等肉毒中毒的临床症状。伤口分泌物检出A型肉毒毒素和肉毒杆菌,血清中也检出A型肉毒毒素。经用肉毒抗毒素、人工呼吸机和创口局部积极治疗,挽救了病人的生命。结合复习文献,讨论本病的诊断要点、治疗原则和预防措施,并指出本例可能系颅脑损伤并发肉毒中毒的首例报告。     

新生儿尿表皮生长因子在判断胎儿成熟度中的价值

临床对胎儿成熟度的评估主要依靠病史、孕妇体检和超声波检查来判断，结果均无准确性，而采用羊膜腔穿刺，检测羊水中各种反映胎儿组织器官成熟的生化指标孕妇往往难以接受。为寻找简便可靠的判断胎儿成熟度的方法，我们对28～41周新生儿血清、尿液、羊水中表皮生长因子(EGF)等进行了检测，现将结果报告如下。
