核医学显像技术在帕金森病中的应用

近年来，帕金森病(PD)发病率逐年增高，但临床上CT和MRI对早期发现PD病变有一定限制，而SPECT和PET等核医学显像技术，特别是多巴胺神经递质及受体显像，对PD的早期诊断有重要价值．

Predicting disease genes for familial dilated cardiomyopathy based on the codon usage bias

Familial dilated cardiomyopathy （FDC） is a common monogenic disease mostly with autosomal dominant inheritance. Fifteen different loci for autosomal dominant FDC have been mapped; however, only eight FDC genes have been found, and it is still a big challenge to identify additional seven FDC genes in their chromosomal regions. We found that the codon usage frequencies in most of known FDC gene sequences are consistently biased, and significantly different from the average codon usage frequencies of human genes. This unique feature of codon usage was used to develop a novel approach to predicting FDC genes. Leave-oneout cross-validation results demonstrate that this approach can effectively detect FDC genes from numbers of genes in their chromosomal regions. Another advantage of this approach is that it is solely based on DNA sequences and therefore has the ability to identify potential FDC genes whose functions are completely unknown. Further, this approach has been used to analyze the seven FDC loci in which the FDC genes are still unknown. Both the detailed prediction results and the prediction program are available at http：// infosci.hust.edu.cn, which might provide help for relevant experimental researches to find new FDC genes.     

一例心理疾病患者的发病情况及探讨

心理疾病是一种与社会、心理因素密切相关的疾病。它的根源是心理素质的不健全。心理素质不仅关系到人的身体健康，也明显关系到人生的成败；有仅关系到个人，也明显关系到家庭和社会，而人性自身有扩展、丰富、发展和完整的自我潜能。因而从理论的高度说明了进行心理健康教育和心理咨询的重要性。

心肌致密化不全研究新进展

目的：了解心肌致密化不全研究进展。方法：复习近十年来的文献，从病因，病理生理，临床表现，诊断治疗和预后等方面进行回顾。结果：心肌致密化不全是一种与遗传因素有关的先天性心脏病，临床上以心功能不全，心律紊乱，血栓栓塞为主要表现。结论：心肌致密化不全临床表现无特异性，超声心动图检查是主要诊断方法，病因研究有待深入。     

亚硫酸氢钠对植物叶片气孔开度的调节作用

章主要研究了不同浓度的ＮａＨＳＯ３、ＡＢＡ对紫鸭趾草和冬青植物叶片气孔开闭运动的影响。结果发现：ＮａＨＳＯ３也能抑制气孔的开启，而且，对木本植物的抑制效果比对草本植物更为明显。这为寻找代替脱落酸等其它传统抗蒸剂的研究，提供了新的研究途径。
