中国健康志愿者单剂口服甲磺酸加替沙星片的药代动力学研究

目的研究中国健康成年志愿者单剂口服甲磺酸加替沙星片的药代动力学。方法按GCP指导原则设计试验方案,选择9名健康受试者分别依次单剂口服200、400、600mg三个剂量的甲磺酸加替沙星片后,应用HPLC测定血药浓度,采用3P97软件进行数据处理,求出药代动力学参数。结果受试者分别给药后,药-时曲线符合二房室模型,主要药代动力学参数Cmax分别为(2.028±0.362)mg/L、(3.749±0.446)mg/L、(4.876±0.569)mg/L;t1/2β分别为(7.489±0.806)h、(7.063±0.890)h、(7.735±0.8701)h;AUC0-t分别为(12.24±1.51)mg·h/L、(26.02±3.38)mg·h/L、(39.22±6.57)mg·h/L;原型药主要经肾排泄,48h尿药累积排泄率分别为(61.90±7.70)%、(60.90±5.70)%和(58.74±13.49)%。结论9名健康受试者分别口服给药后,药-时曲线符合二房室模型,甲磺酸加替沙星在200～600mg剂量范围内药物体内过程呈线性动力学特征而无饱和性,主要排泄途径为肾脏。

Telescopic Examination of the mastoid Cavity

Otoendoscopy enables viewing of different angles of the tympanomastoid area and approach to them for better prognosis. A comparative study of post-operative mastoid cavities has been done using the Hopkin’s rod telescope, Otoscope and microscope. Various procedures have also been done successfully on the mastoid cavity using the telescope on an outdoor basis.     

Tumours of the parapharyngeal space

A series of 14 parapharyngeal tumours has been studied with regard to their symptology, pre-operative evaluation and surgical management. High resolution computed tomography is now the best initial diagnostic study because it helps to determine the size and extent of the tumour, differentiate tumours of parotid and extraparotid origin, demonstrate degree of tumour vascularity, separate benign from malignant lesions, plan the surgical approach and predict prognosis.     

Synovial sarcoma of the larynx

A 23 years old male presented with a soft cystic mass in the left paralaryngeal space since 3 months. Indirect laryngoscopy revealed a bulging of the left lateral pharyngeal wall. Histopathologic al examination of the biopsy proved it to be a synovial sarcoma. The case is the seventh case reported in literature.     

河套大黄非蒽醌类成分研究

从河套大黄干燥根与根茎的甲醇提取物中分得8个非蒽醌类成分。经化学和波谱方法，确定它们的结构分别为：β-谷甾醇（β-sitosterol，Ⅰ）、土大黄苷元（rhapontigeni，Ⅱ）、没食子酸（gallicacid，Ⅲ）、3－（3’，5’-二羟基-反式-肉桂酰基）－5-羟基-△5－α-吡喃酮[3－（3’，5’－dihydroxyl－trans－cinnamoyl）－5－hydroxyl－△5’－α－pyranone，Ⅳ]、胡萝卜苷（daucosterol，Ⅴ）、piceatannol－3’－O-β-D-glucopyranoside（Ⅵ）、土大黄苷（rhaponticin，Ⅶ）和蔗糖（Ⅷ）。其中Ⅳ为一新化合物，命名为波叶素（rheumin）。Ⅰ、Ⅲ、Ⅴ、Ⅵ和Ⅷ系首次从该植物中获得。     

Effects of Electroacupuncture on the Number of NK-1R／IL-1β Double Labeled Immunofluorescent Positive Cells in th_e Epidermal and Subcutaneous Tissue Around the Ankle Joint of Adjuvant Monoarthritis in Rats

Adjuvant monoarthritis was induced by the injection of 50μl Complete Freund‘s Adjuvant（CFA) into ankle joint of adult SD rats. Electroacupuncture (EA)was performed on Huantiao (GB30)and Yanglingquan (GB 34) (0.5-1.5 v, 4-16 Hz, 30 min) after the injection.     

难治性癫痫的24小时脑电监测临床意义

目的探讨24h脑电(AEEG)监测对难治性癫痫的临床意义。方法对96例难治性癫痫患者进行连续24hAEEG监测。结果AEEG痫波阳性率为64.29%,与常规EEG的28.21%相比较,差异有极显著意义(P<0.001)。且痫样放电与睡眠密切相关。96例患者中捕获41例(42.71%)临床发作,其中31例确诊为癫痫发作;2例癫痫合并假性发作;3例假性发作;3例睡眠呼吸暂停综合征(SAS);2例癫痫合并SAS。结论24hAEEG携带方便,监测期间自然睡眠不受环境改变的影响,显著提高了临床癫痫发作和痫样放电阳性率,还可作为难治性原因之一SAS的筛查检测,有助于难治性癫痫的诊断和鉴别诊断。
