坎离颗粒加载对慢性心力衰竭患者骨骼肌受损的影响

Effects of added therapy with Chinese herbal medicine Kanli Granule on skeletal muscle dysfunction in patients with chronic heart failure

背景:慢性心力衰竭(chronic heart failure,CHF)时骨骼肌功能受损的病理改变已被广泛关注,但临床该如何评价,用何种药物干预能改善这种病理变化已成为临床医生普遍关注的问题。目的:研究CHF患者骨骼肌功能受损的情况,以CHF西药基础治疗作为对照,观察中药坎离颗粒加载干预对CHF患者骨骼肌功能受损的影响。设计、场所、对象和干预措施:所有纳入的病例均为2005年12月~2007年12月在上海中医药大学附属曙光医院门诊就诊或住院治疗的CHF患者,分为西药组(CHF西药基础治疗)和中药加载组(CHF西药基础治疗加坎离颗粒);疗程为12周。主要结局指标:观测治疗前后患者握力、手握次数、主观体力感觉等级(rating of perceivedexertion,RPE)积分、估算心率、末梢血乳酸水平、血乳酸脱氢酶(lactate dehydrogenase,LDH)同工酶活性等指标变化。结果:共纳入92例患者,试验中程西药组退出12例,共80例患者进入后续研究,其中中药加载组46例,西药组34例。治疗后,两用药组握力及握次均较治疗前明显增加,RPE积分及估算心率均较治疗前显著下降,中药加载组较西药组变化更明显(P<0.01)。治疗后CHF患者静息状态下末梢血乳酸水平均有所下降,中药加载组下降更为显著(P<0.05);两组运动3 min后乳酸水平治疗后有下降趋势,但与治疗前比较差异无统计学意义;两组患者LDH1均有不同程度的降低,但与治疗前相比差异无统计学意义;两组LDH5治疗后均有升高,中药加载组升高更为显著(P<0.01)。结论:中药坎离颗粒加载治疗能显著减轻CHF患者骨骼肌功能受损,改善骨骼肌能量代谢可能为其药效机制之一。

BACKGROUND： The pathological changes of skeletal muscle dysfunction in chronic heart failure （CHF） have caused widespread concern, and evaluating the functional properties of medication to improve these pathological changes has become a common area of study for clinicians. OBJECTIVE： To investigate the characteristics of skeletal muscle dysfunction in patients with CHF and the effects of Kanli Granule, a compound traditional Chinese herbal medicine, on the skeletal muscle dysfunction based on Western medical treatment in patients with CHF. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： All patients with CHF enrolled in this study were outpatients or inpatients in Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine from December 2005 to December 2007. The patients were divided into Western medicine group （treatment with Western medicine） and Chinese herbs group （treatment with Kanli Granule based on Western medicine） based on their preference. The treatment course lasted for 12 weeks. MAIN OUTCOME MEASURES： The grip strength, grasp times, rate of perceived exertion （RPE）, estimated heart rate, peripheral blood lactate levels and lactate dehydrogenase （LDH） isoenzyme activity in patients were measured. RESULTS： A total of 92 patients were recruited and 12 patients withdrew from the Western medicine group, therefore a total of 80 patients were included in the follow-up study. There were 46 cases in the Chinese herbs group and 34 cases in the Western medicine group. After treatment, grip strength and grasp times increased significantly compared with before treatment. RPE score and estimated heart rate significantly decreased in the two groups, showing greater changes in the Chinese herbs group than the Western medicine group （P~ 0.01）. Peripheral blood lactate levels of the CHF patients in a resting state decreased, and the Chinese herbs group displayed a greater decrease than the Western medicine group （P^0.05）; lactate levels 3 min after exercise decreased after treatment in both treatment groups, but no significant difference was found compared with before treatment; LDH1 levels in the two treatment groups were decreased compared with before treatment but showed no statistically significant changes; LDH5 levels in the two treatment groups increased after treatment, and an obvious difference was found in the Chinese herbs group （P〈0.01）. CONCLUSION： Treatment with the addition of Kanli Granule can significantly improve the function of skeletal muscle in patients with CHF by improving skeletal muscle energy metabolism.
