维生素D在结核病防治中的作用

维生素D与结核病关系密切，经临床实验约有50％以上的结核病人血清中维生素D的水平低下。其原因主要有二点：（1）病人饮食中维生素D含量不足，接受日光照射少而体内合成不足；（2）抗结核药物利福平、异烟肼也可引起血清中维生素D的含量下降。因此结核病人就有维生素D缺乏的危险性，甚至造成软骨病。为防止结核病人因维生素D缺乏引起更多的并发症，专家建议将维生素D做为抗结核病的辅助治疗药物应用。据国外有关资料报道，将维生素D做为抗结核辅助治疗，除可以直接纠正血清维生素D含量不足，避免软骨病等危害外，还可以从以下三个方面对病人有益处。

Clearance of beta- amyloid from the CSF by the choroid plexus： implications in drug development for treatment of Alzheimer＇s disease

The formation of insoluble aggregates of beta - amyloid peptide （ A ） within the brain extracellular fluid is a critical event in the etiology of Alzheimer＇s disease （AD）. In theory, an unbalanced A kinetics can be due to its over production, inadequate metabolic cleaning, or an improper balance of import or export of A or related molecules at brain barriers. We investigated the role of the choroid plexus, which forms a barrier between blood and brain cerebrospinal fluid （ CSF）, in regulating A in the CSF. A uptake from CSF was determined as its volume of distribution （ VD ） into isola- ted rat choroid plexus tissue by using [^125I] A 1-40 and along with a extracellular space marker [^14C ] sucrose. The choroid plexus exhibited a definite capacity in sequestering [^125I] A 1-40 from the surrounding CSF. Uptake of [^125I] A by the choroid plexus was saturable, time - and temperature - dependent, and not ttffected by addition of transthyretin or apolipoprotein E3. Studies with cultured monolayers of primary choroid epithelial cells indicated that A permeability across cells, corrected by [ ^14C] sucrose, was greater from the CSF -facing membrane than from the blood -facing membrane. Similarly, cellular accumulation of [ ^125 I ] A was concentrative from both directions and was greater from the CSF -facing membrane. Quantitative real- time RT- PCR, immunodetection and enzyme activity assays further revealed the presence of several key enzymes involved in A production, e. g. , amyloid precursor protein and beta - secretase, and in A metabolism and alternate processing, e. g. , insulin degrading enzyme, endothelin - converting enzyme - 1, neprilysin and alpha - secretase. Overall, these results suggest the choroid plexus selectively cleanses A from the CSF by an undetermined mechanism （s） ; moreover, it has the capacity to degrade A , suggesting a vital role of this tissue in maintaining A homeostasis. The perspectives of drug development for treatment of AD by reducing A from brain extracellular fluid as a new strategy will be discussed.

无创正压通气联合激素治疗急性氯气中毒致ARDS 1例

氯气为高水溶性刺激性气体，在水中溶解度大，在眼和呼吸道的潮湿组织表面很快溶解形成酸类物质和新生态氧，产生强烈的刺激和氧化作用。氯气中毒临床症状可为：眼和上呼吸道的刺激症状、急性气管支气管炎、中毒性肺炎、急性呼吸窘迫综合征以及迟发性阻塞性细支气管炎等。现将我科收治的急性氯气中毒致ARDS使用无创正压通气抢救成功1例报告如下。     

顽固性下颌磨牙根尖周炎患者的治疗和护理讨论

目的治疗顽固性下颌磨牙根尖周炎。并尽量减少对牙周膜的机械性损伤。方法采用下牙槽神经阻滞麻醉,并配合局部麻醉。拔牙钳的尖置放于釉牙骨质界以上,采用颊舌向摆动的方式将患牙拔下。在不断滴有生理盐水的条件下,立即用高速车针磨除患牙根尖2￣3mm的牙体组织,根管内3￣5mm深的充填物要用圆钻将其清除,再用牙胶尖和氢氧化钙糊剂充填。将患牙再植入牙槽窝之前,务必用生理盐水将牙槽窝冲洗干净,要求严格控制在15分钟内完成再植,并尽量减少对牙周膜的机械性损伤。再植牙齿一般不需要夹板固定,必要时可采用缝线缝合固定。结果我们选择的5例患者,术后随访1￣2年,1例患者再植失败,4例患者再植成功。结论特异性再植术治疗顽固性下颌磨牙根尖周炎疗效理想,而且较易掌握。
