关于Reed－Frost模型的研究和改进

笔者提出了对Ｒｅｅｄ－Ｆｒｏｓｔ模型的学术评论，并新建了一种Ｒｅｅｄ－Ｆｒｏｓｔ模型的改进模型。该改进模型全面考虑了隐性感染者的产生、传染作用及向免疫者的转化。应用这个模型，模拟了ＮｅｗＥｎｇｌａｎｄ的麻疹流行和中国上海市某保育院的水痘流行，结果颇为理想。该模型包括了基本的流行要因，故能用以解释流行过程，并可帮助流行病学工作者理解隐性感染在传染病流行过程中的作用。     

Serotonergic projections from the midbrain periaqueductal gray and nucleus raphe dorsalis to the nucleus parafasccicularis of the thalamus

By a double-labeling method combining the retrograde tracing of horseradish peroxidase and the immunocytochemical technique, serotonin-like immunoreactive neurons in the midbrain periaqueductal gray (PAG) and nucleus raphe dorsalis (DR) of the rat were observed to send projection fibers to the nucleus parafascicularis of the thalamus bilaterally with an ipsilateral dominance. These serotonin-containing projecting neurons were observed mainly at the middle-caudal levels of the ventrolateral subdivision of the PAG and less at the middle-rostral levels of the DR.     

心肌肌凝蛋白轻链—1的免疫组化研究

为了研究心肌肌凝蛋白轻链－１（ＣＭＬＣ－１）组织特异性的特点，并对其构型在心肌发育过程中的表达规律以及不同哺乳动物ＣＭＬＣ－１构型的生化规律进行探讨，应用抗人心室肌ＣＭＬＣ－１，单克隆抗体（ＭｃＡＢ）对成人和不同胎龄胎儿的心肌和其它组织，不同种属哺乳动物的心肌进行了免疫组织化学研究。结果发现：成人心室肌，慢性骨骼肌均发生强烈反应，成人心房，胎儿心室肌发生交叉反应，而其它组织加快骨骼肌，平滑肌以及肌     

The use of 6-flavor Rehmannia decoction with additives in the prevention of ototoxic deafness induced by gentamicin in guinea pigs]

The purpose of this study is to discuss the effects of the Chinese medicine six-flavor Rehmannia Decoction with additives on preventing deafness induced by gentamicin (GM) in guinea pig by means of testing the thresholds of Preyer's reflex (PR) cochlear microphonic potential (CM), action potential of the auditory nerve (N1) and scanning electron microscope of inner ear (SEM). The results showed that the medicine is effective in reducing the ototoxic effect of GM on inner ear.     

Teriparatide increases bone formation in modeling and remodeling osteons and enhances IGF-II immunoreactivity in postmenopausal women with osteoporosis.

Transiliac bone biopsies were obtained from 55 women treated with teriparatide or placebo for 12-24 months. We report direct evidence that modeling bone formation at quiescent surfaces was present only in teriparatide-treated patients and bone formation at remodeling sites was higher with teriparatide than placebo. INTRODUCTION: Recombinant teriparatide [human PTH(1-34)], a bone formation agent for the treatment of osteoporosis when given once daily subcutaneously, increases biochemical markers of bone turnover and activation frequency in histomorphometry studies. MATERIALS AND METHODS: We studied the mechanisms underlying this bone-forming action of teriparatide at the basic multicellular unit by the appearance of cement lines, a method used to directly classify surfaces as modeling or remodeling osteons, and by the immunolocalization of IGF-I and IGF-II. Transiliac bone biopsies were obtained from 55 postmenopausal women treated with teriparatide 20 or 40 microg or placebo for 12-24 months (median, 19.8 months) in the Fracture Prevention Trial. RESULTS: A dose-dependent relationship was observed in modeling and mixed remodeling/modeling trabecular hemiosteons. Trabecular and endosteal hemiosteon mean wall thicknesses were significantly higher in both teriparatide groups than in placebo. There was a dose-dependent relationship in IGF-II immunoreactive staining at all bone envelopes studied. The greater local IGF-II presence after treatment with teriparatide may play a key role in stimulating bone formation. CONCLUSIONS: Direct evidence is presented that 12-24 months of teriparatide treatment induced modeling bone formation at quiescent surfaces and resulted in greater bone formation at remodeling sites, relative to placebo.

Cervifix内固定系统在枕颈融合术中的应用

目的 介绍Cervifix枕颈内固定系统在枕颈融合术中的应用并评价其疗效。方法 对6例由新鲜创伤和25例由陈旧性创伤、先天畸形、类风湿引起的枕颈失稳病例，采用Cervifix系统进行枕颈融合术；随访手术效果。结果 全部病例得到随访，随访时间9～37个月。3l例均获得骨性融合。内固定无松动，移位和断裂等并发症。脊髓神经功能有不同程度恢复。l例在术中发现有椎动脉损伤，术后无相关症状出现。所有病例未出现与内固定有关的神经脊髓损伤和脑脊液漏等并发症。结论 Cervifix系统固定可靠，器械安装方便，手术操作虽有一定难度，但仍是目前枕颈融合内固定的较好方法：     

葡萄球菌的原生质体融合及遗传转移

本文报道在金黄色葡萄球菌多剂抗生素耐药菌株(22)及白色葡萄球菌(Rif~r,Nal~r)间进行的原生质体融合试验。在高渗缓冲培养基中,将对数生长期中、后期的培养物,以溶菌酶及溶葡萄球菌素处理,DM_3培养基再生得原生质体。将二亲本葡萄球菌的原生质体混合,以CaCl_2及PEG(6000)处理使发生融合及种间遗传转移。根据重组子的色素、耐药性及在琼脂糖凝胶电泳中显示的质粒带进行遗传分析,证明在金黄色葡萄球菌及白色葡萄球菌中,质粒和染色体的遗传标记均可相互转移,再次证实在金黄色葡萄球菌(22)中存在分子量为2.0Mdal的pcr质粒。
