简介:摘要 本文通过临床龙胆泻肝汤使用病例的阐述,揭示中医辩证施治的灵魂,增强对“异病同治”、“一方治百病”的理解,对临床所现的肝胆湿热郁结、阴不虚症的辩证治疗具有提示和指导意义。
简介:摘要:本文在常规L波段收发组件的基础上,通过增加开关矩阵及耦合器来设计新型收发组件,新型收发组件可以在不增加端口数量的前提下,实现多种定标工作模式。并对组件开展研制工作,最终的实测结果满足设计预期。
简介:摘要目的探讨血小板表面CD40L和血清可溶性CD40L(sCD40L)与急性冠脉综合征(ACS)的关系。方法选取ACS患者32例(心肌梗死14例、不稳定心绞痛18例),稳定性心绞痛患者13例,同时选取10例健康成人作对照。分别应用流式细胞术和ELISA法测定血小板表面CD40L及血清sCD40L水平。随访ACS患者1月,测定其血清sCD40L水平。结果FCM测定结果显示,AMI组和UA组血小板表面CD40L表达水平明显高于SA组及对照组(P<0.05),UA组CD40L水平显著高于AMI组(P<0.05),SA组与对照组比较无显著差别;ELISA测定血清sCD40L结果显示,AMI组和UA组血清sCD40L表达水平明显高于SA组及对照组(P<0.05)。AMI组sCD40L水平显著高于UA组(P<0.05),SA与对照组比较无显著差别。结论急性冠脉综合征患者血小板表面CD40L表达增加,血清sCD40L水平升高,因此CD40L可能成为预测斑块稳定状态的一个指标。
简介:目的探讨N(2)-L-丙胺酰-L-谷氨酰胺治疗重症患者肠功能障碍的效果.方法将96例重症并发肠功能障碍患者,随机分为观察组和对照组,每组48例,两组患者均在治疗原发病的基础上给予肠外营养治疗,观察组肠外营养液中加入N(2)-L-丙胺酰-L-谷氨酰胺0.4g/kg·d,对照组采用传统的肠外营养液,疗程均为10d.治疗前后采用LIFE评分及APACHE-Ⅱ评分对两组患者肠功能进行评估.结果治疗后,两组患者的LIFE评分及APACHE-Ⅱ评分均较治疗前降低,观察组患者降低较对照组明显,两组比较差异有统计学意义(P<0.05).结论重症患者肠功能障碍早期给予N(2)-L-丙胺酰-L-谷氨酰胺治疗,能有效地预防肠道黏膜萎缩,增强小肠和结肠黏膜细胞的活性,改善肠道的结构和吸收功能.
