益气化瘀解毒方对MRP、GST-π和Topo Ⅱ基因在Sorafenib获得性耐药人肝癌QGY7702细胞表达的干预研究

目的探讨益气化瘀解毒方干预后对Sorafenib获得性耐药人肝癌QGY7702细胞(QGY7702/Sora)增殖及MRP、GST-π和Topo Ⅱ基因表达的影响。方法培养QGY7702/Sora细胞和QGY7702细胞,利用Cell Counting Kit-8(CCK-8)法检测Sorafenib对细胞的半数抑制率浓度(IC50值),计算耐药指数RI;观察益气化瘀解毒方对耐药细胞的增殖影响;采用荧光定量PCR检测药物干预前后2种细胞中MRP、GST-π和Topo Ⅱ基因表达水平。结果亲本细胞和耐药细胞Sorafenib的IC50值分别为(7.993±0.522)μmol/L和(19.651±1.216)μmol/L,RI约为2.5。益气化瘀解毒方可抑制耐药细胞的增殖活性。2种细胞的MRP、GST-π、Topo Ⅱ表达量无明显差异(P>0.05)。Sorafenib组可促进耐药细胞MRP 、GST-π基因的过表达(P<0.05),益气化瘀解毒方组可抑制GST-π基因的过表达(P<0.01),且联合Sorafenib可显著提高Topo Ⅱ基因的表达量(P<0.01)。结论 QGY7702/Sora细胞MRP、GST-π和Topo Ⅱ的表达水平与亲本细胞无显著差异。耐药细胞对Sorafenib敏感性降低与MRP、GST-π过表达相关,而益气化瘀解毒方拮抗Sorafenib耐药与抑制GST-π过表达相关。     

急诊抗菌药物的使用调查与分析

目的考察了解急诊抗菌药物的使用情况。方法随机抽取2008年7—12月的急诊处方2700张，对其中抗菌药物的应用情况进行统计分析。结果急诊抗菌药物使用率49．1％，药物应用形式以单用为主（占66．3％）；给药途径以口服和静脉注射为主。不合理用药处方占抗菌药物处方的10．8％，分别在选药方案、给药方案、溶媒使用、联合应用等方面存在问题。结论我院急诊抗菌药物的应用基本合理，但仍存在一定问题，需进一步加强管理。

Clonidine Use and Abuse Among Methadone Program Applicants and Patients

Forty-eight consecutive applicants and 30 known clonidine-abusing methadone patients at three methadone treatment programs were surveyed regarding their use of clonidine. Two distinct patterns of clonidine use emerged. Of 22 applicants who took clonidine illicitly, 15 used it primarily to decrease opioid withdrawal, as well as for its sedating effect. Applicants mostly obtained it from physicians, used an average dose of 0.37 mg at a time, and about one third believed clonidine to be addictive. In contrast, clonidine-using patients took clonidine primarily for its psychoactive effects, including the interaction with methadone, in addition to decreasing opioid withdrawal. Patients obtained clonidine frequently on the street and from family or friends, but less from physicians. The average reported dose for patients was 0.6 mg. The vast majority of these patients felt clonidine was addictive. Our findings, when coupled with the risk inherent in clonidine overdose, suggest that further research into the identification and treatment of clonidine abuse among methadone patients is warranted.     

白术茯苓汤及其配伍对脾虚大鼠胃肠激素的影响

目的：探讨益气健脾方剂治疗脾虚证的配伍规律。方法：采用苦寒泻下法复制大鼠脾虚模型，运用放射免疫分析法（RIA）检测白术茯苓汤及其与补气药。行气药及除湿药的不同配伍对脾虚大鼠胃泌素（GAS）、胃动素（MTL）及血管活性肠肽（VIP）的含量影响。结果：与正常对照组比较，脾虚模型大鼠GAS、MTL降低（P＜0．01），VIP升高（P＜0．01）；与自然恢复组比较，各治疗组以上部分或全部指标均有不同程度的改善，其中，以综合配伍组改善作用最优。结论：白术茯苓汤的脾虚大鼠胃肠激素的紊乱的某些指标，有一定的改善作用，综合配合组以上指标的改善，优于白术茯苓汤组及其余各配伍组，说明中医关于复方配伍的理论与实践，有其科学价值。

Lähmung des N. hypoglossus nach operativem Eingriff – Behandlung mit Akupunktur

Acupuncture is able to accelerate the process of healing significantly when employed in cases of nerve paresis as shown in the following analysis. The patient's constant condition of speech and swallowing impediment before treatment changed relatively fast after starting acupuncture treatment. It is self evident that we took into account the primary disease (AIDS) and its problems. The simplicity of a complementary treatment with acupuncture according to the possible results should make us consider the use of acupuncture as an important way to treat paresis in the early subacute phase and if possible during clinical stay.
