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.

Oxygen uptake-heart rate relationship in élite wheelchair racers

The American College of Sports Medicine (ACSM) recommends that, as a general rule for health purposes, individuals should exercise at 40%–85% of their maximal oxygen uptakes. Moreover, it has been suggested that 55%–90% of the maximal heart rate may be used as an alternative estimate of these percentage maximal oxygen uptake values. The present study examined the relationship between percentage peak heart rate (% HR_peak) and percentage peak oxygen uptake (% ) during steady-state incremental intensity wheelchair propulsion of 16 élite, male wheelchair racers (WR). Oxygen uptake was determined during each submaximal exercise stage and heart rate (HR) was continuously monitored. The was subsequently determined using a separate protocol. Linear regression equations of % HR_peak versus % for each participant included % HR_peak values corresponding to 40%, 60%, 80% and 85% . The linear regression equation, derived as the group mean of the slope and intercept terms determined for each individual, was: . The group mean of the individual correlation coefficients for the relationship was 0.99. The values of % HR_peak for each of the % values below 85% were significantly greater (P<0.01) than those suggested by the ACSM. This suggests that the ACSM guidelines below 85% , based on % HR_peak, may underestimate the relative exercise intensity (i.e. % ) in the WR population. However, in élite level WR, % HR_peak can be recommended as an alternative estimate of % at wheelchair propulsion intensities of 85% or more. Electronic Publication     

基于古今文献对经典名方中细辛毒性的有效避减探析

目的：通过研究细辛的相关文献,对影响细辛毒性的关键信息进行梳理,为经典名方中细辛的合理应用提供依据。方法：通过文献计量学的方式,搜集细辛的古今相关文献,分析细辛毒性与药物基原、用药部位、炮制方式、药物剂型、方药配伍、服药方法及患者体质因素之间的关系。结果：在经典名方的研发过程中,细辛在当归四逆汤、厚朴麻黄汤中的用量分别为9、6 g,煎煮时间应>120 min;细辛在辛夷散、三痹汤、大秦艽汤、清上蠲痛汤种的单次用量分别为0.8、1.2、0.9、1.1 g;当归四逆汤、厚朴麻黄汤、清上蠲痛汤等应选用辽细辛的根茎,辛夷散可选择汉城细辛的根茎。在药物的炮制上,当归四逆汤、厚朴麻黄汤、三痹汤、大秦艽汤四方中的细辛可选用酒制;辛夷散、清上蠲痛汤中的细辛可选用炒制;另外,细辛的毒性与药物的配伍和患者的体质等因素均有着密切的关系。结论：该研究通过梳理有关细辛毒性的文献资料,得出了影响细辛毒性的关键信息,探析了细辛毒性的有效避减方式,为包含细辛的经典名方的合理开发和安全应用提供了更为充分的依据。     

经典名方当归补血汤的古代文献分析与考证

当归补血汤出自金元时期李东垣《内外伤辨惑论卷中·暑伤胃气论》,是一首被历代医家传承发扬的补气生血经典名方,已被收录于2018年国家中医药管理局公布《古代经典名方目录（第一批）》。通过系统梳理古籍文献及现代文献,并结合古代经典名方关键信息考证原则,对经典名方当归补血汤的历史源流、组成、剂量、炮制、制法与煎服法、功效与应用进行考证分析。共收集相关古籍文献信息604条,其中涉及中医古籍186部,其中40部（金元5部,明19部,清16部）中医古籍详细记载了组成、炮制、剂量等内容。有关当归补血汤组成,主要为当归和黄芪;根据古今剂量折算,黄芪37.3~38.1 g,当归7.5~7.6 g;黄芪宜采用蜜炙,当归为酒当归;加入水600 mL,煎至300 mL,饭前温服。该方古籍主要记载功效为血虚发热,证见肌热、燥热,烦渴引饮,目赤面红,昼夜不息,脉洪大而虚,重按无力,是补气生血名方。现代研究表明,当归补血汤常用于治疗各种贫血、糖尿病肾病、肿瘤、心脑血管疾病。上述研究结果为经典名方当归补血汤后期开发研究提供了参考依据。
