阿德福韦酯治疗慢性乙型肝炎疗效观察

目的评价阿德福韦酯（ADV）治疗成人慢性乙型肝炎患者72周的疗效和安全性。方法采用多中心、随机、双盲、安慰剂平行对照的研究设计。分ADV组（A组）和安慰剂组（B组）两组进行两个阶段：第一阶段128例患者随机进入ADV组（A组，61倒）或安慰剂组（B组，67例）双盲阶段12周，分别口服ADVIOmg或安慰剂1粒，1次／d；第二阶段患者均接受开放的ADV治疗36周。主要疗效评估指标为血清HBV DNA的变化情况，次要疗效评估指标为丙氨酸氨基转移酶的复常率与HBEAG转阴率、HBEA6妁血清转换率。结果治疗12周时，A组的HBV DNA水平较B组明显下降（p=0.000）。治疗48周时，A组和B组的HBV DNA水平接近（p〉0.05）,安全性方面，与药物相关的不良事件的发生率为5．65％。     

芳香族聚酯的相转移催化合成及其介晶态行为的研究——Ⅰ.聚酯的合成及介晶态行为

本文用相转移催化方法合成了四种新颖的芳香族聚酯。对所得聚合物进行了红外光谱、热重分析、偏光显微镜、示差扫描量热仪和解偏振光强等测试,以研究它们的结构和性能。它们的热分解温度都在330℃以上。其中的聚对,对′-1,4,7-三氧杂庚撐基二苯甲酸对苯二酚酯和聚对苯二甲酸对,对′-1,8-二氧杂辛撐基二苯酚酯,呈现向列型相转变,它们的清晰点分别为237℃和327℃。其它两种含双酚A或酚酞基团的聚酯则不存在液晶行为。对实验结果进行了讨论。

Changes in T .lymphocyte subsets after severe traumatic brain inJury

BACKGROUND： Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE： To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN： A comparative observation. SETTINGS： Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS： All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score （GCS） was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16 - 62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group （GCS ranged 14- 15 points）, including 18 males and 12 females, aging 15 -58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury Informed consents were obtained from all the patients or their relatives. METHODS： （1） The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at l, 3, 7 and 14 days after injury in both groups. （2） The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES： Changes of T lymphocytes subsets at 1 - 14 days after severe and mild or moderate traumatic injury. RESULTS： Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. （1） Changes of T lymphocyte subsets： At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group （t =2.77 - 3.26, P 〈 0.01）, and began to recover at 7 days, which were significantly different from those in the control group （t = 2.06 - 2.24, P 〈 0.05）, and generally recovered to the normal levels at 14 days （P 〉 0.05）. （2） Conditions of pulmonary infections： At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% （22/30）, 0, x2=37.29, P 〈 0.01]. CONCLUSION： Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period （within 7 days）, and they are easily to be accompanied by pulmonary infections.     

青蒿琥酯皮肤擦剂在小鼠和兔体内的药代动力学研究

将青蒿琥酯溶于苯二甲酸二甲酯,加适量氨酮制成皮肤擦剂。给兔脱毛后,皮肤涂抹此擦剂25mg/kg后,血药浓度达峰时间平均为2 h,峰浓度平均为1.80μg/ml。药物在兔体内平均驻留时间为3.54 h,清除半衰期约为2.46 h。给小鼠脱毛皮肤涂抹擦剂6.7,31.3和71.4 mg/kg,血药浓度在给药后0.5～4 h达高峰,峰浓度分别为0.82,2.05和7.11μg/ml,体内药物平均驻留时间为3.39,2.79及3.54 h,清除半衰期为2.35,1.93及2.45 h。可见,给兔及小鼠皮肤擦剂后,青蒿琥酯吸收良好,血药浓度维持时间较长。     

胆碱酯酶抑制剂-激素-大剂量血浆置换联合治疗重症肌无力的评价

重症肌无力（MG）是一组以病态疲劳为主要临床表现的自身免疫性疾病，其发病机制为横纹肌终板受乙酰胆碱受体抗体（AchRab）损害，从而造成终板AchR数量下降，功能降低。因此，AchRab在MG发病中占主要地位，血浆置换（PE）是以健康人血浆及血浆代用品替换患者血浆，快速去除患者血浆中AchRab及免疫复合物，从而使乙酰胆碱能正常与AchR结合，达到治疗目的。本研究通过观察接受及未接受PE治疗的MG患者病情转归，评价PE在MG治疗中的价值。     

乳剂依托咪酯对心脏手术病人麻醉诱导期循环功能的影响

目的　本文应用乳剂依托咪酯,观察其对心脏手术病人麻醉诱导期的循环影响。方法　选择心脏手术病人80例,心功能Ⅲ～Ⅳ级,随机分为两组,每组2 0例:Ⅰ组(水剂组) :水剂依托咪酯0 2 5mg kg-1;Ⅱ组(乳剂组) :乳剂依托咪酯0 2 5mg kg-1。记录麻醉前、注射依托咪酯前、后,气管插管后1min和3min时段的各监测参数。观察不自主肌肉颤动,注射疼痛感及过敏反应等不良反应。结果　显示两种剂型的依托咪酯各时间点的SBP、DBP、MAP、HR各组间无显著差异(P >0 0 5 )。两组在注射依托咪酯后SBP、DBP、MAP、HR轻度下降,但与注射前均无统计学差异(P >0 0 5 )。不自主肌肉运动Ⅰ组8例、Ⅱ组6例:两组间无显著差异(P >0 0 5 )。静脉注射处疼痛Ⅰ组14例、Ⅱ组1例,两组间显著差异(P >0 0 5 )。结论　乳剂依托咪酯具有麻醉诱导平稳,心血管影响轻微,副作用少在应用上优于水剂依托咪酯,可用于高龄及心脏功能受损害患者的麻醉诱导。     

西洋参茎叶皂苷与胸腺肽对CPHD病人细胞免疫功能的比较研究

随着临床免疫分子学的深入研究，细胞免疫越来越倍受重视，尤其在呼吸系统疾病中，如CPHD患者细胞免疫功能常常低于正常人，其T淋巴细胞亚群及淋巴细胞转化率有明显异常，呈下降的趋势。T细胞的改变与细菌感染、病毒感染密切相关。CPHD为慢性炎症性疾病，中性粒细胞释放蛋白酶及氧化物引起肺部损伤和肺气肿是疾病持续进展的主要原因之一。
