可治愈医源性腹泻的新型抗生素

在难辨梭状芽孢杆菌引起的腹泻患者（CDAD）中进行的Ⅱ期临床试验证明：新型抗生素PAR-101效果显著。难辨梭状芽孢杆菌引起的腹泻危害到越来越多使用抗生素治疗，而且这种疾病对现有的抗生素有耐药性。比如目前最常用的甲硝唑，感染CDAD致病株后，死亡率相当高并且当前的治疗收效甚微。     

抗病毒药物研究

在1981年，获得性免疫缺陷综合症（AIDS，又称艾滋病）作为一种新型疾病首次被报道；1984年，人们终于查明引起这种疾病的病毒是人类免疫缺陷病毒（HIV）；从此，艾滋病（AIDS）就被确定成为威胁世界健康的主要疾病。全世界感染HIV病毒的患者预计有4．000万人，其中儿童患者超过200万，在许多国家，艾滋病（AIDS）引发了严重的经济困难。去年，仅撒哈拉沙漠以南的中部非洲地区死于艾滋病（AIDS）的人就有240万，而死于疟疾的人也只不过100万。     

The clinical analysis of secondary hypertension patients

Objective To analyze the situation of secondary hypertension caused by different etiology and its treatment status so as to improve its treatment. Methods Totally 580 patients with secondary hypertension selected with strict criteria were divided into 4 groups in accordance with the etiology. The data were dealt with SPSS 13.0. We analyzed the sex, age, systolic pressure, diastolic pressure and positive incidence of family history of all the secondary hypertension patients in each group, and compared their usage of every unilateral preparation. Results The average age of renal parenchymal disease was more advanced than that of adrenal disease and other diseases. The administration of diuretics and angiotensin-converting enzyme inhibitor (ACEI) in renal parenchymal disease group, αβ receptor blocking agents and calcium antagonists in kidney-artery disease group, a antagonists in adrenal disease and compound antihyportensive agents in other diseases groups all affected advantage of the ratio. Conclusion Diuretics and ACEI are suitable for hypertension caused by renal parenchymal disease, αβ receptor blocking agents and calcium antagonists are suitable for that caused by kidney artery disease, but a receptor blocking agents are suitable for that caused by adrenal disease.
