中药生物效价研究现状及开发思路探讨

中药质量控制一直是中药现代化的重点和难点,如何证明产品的质量一致性和临床疗效一致性,是中药创新与发展探索的重要方向。由于中药天然存在的异质性,有必要在现有检测方法的基础上结合生物效价方法,以更全面地保证药品质量。拟从中药生物效价研究现状出发,系统总结和分析现行国内外法规对植物药/中药生物效价建立过程的要求与建议、现阶段研发的难点及探索,并对基于中药药动学-药效动力学(pharmacokinetic-pharmacodynamic,PK-PD)特点的适宜效价方法的开发思路进行探讨,为中药质量评价体系的构建提供思路,促进国际药政管理部门对中药质量标准的认可。     

川芎药材、饮片及其中成药抗血小板聚集活性的生物检定方法学研究

目的建立以抗血小板聚集活性为指标的生物检定法,评价川芎药材、饮片及含川芎中成药的质量。方法川芎加水回流定量提取,以提取物为供试品体外测定抗血小板聚集活性。家兔心脏取血,制备富血小板血浆(PRP),用腺苷-5′-二磷酸钠盐诱导血小板聚集,以血小板抑制率为抗血小板聚集活性指标,用阿魏酸钠标定川芎提取物的抗血小板聚集活性。根据量反应平行线法(2.2)法计算川芎提取物的抗血小板聚集活性;结合川芎水提物的提取率,计算川芎样品抗血小板聚集活性。并测定了8份川芎药材、饮片及中成药样品的抗血小板聚集活性,验证方法的可行性。结果阿魏酸钠和川芎提取物均具有显著抗血小板聚集活性(P0.01),并且可靠性检验结果成立。阿魏酸钠在给药质量浓度15~60 mg/m L内与其血小板聚集抑制率呈良好的线性关系(r=0.993 4,n=4)。供试品重复测定抗血小板聚集活性的RSD值为3.43%(n=6),可信限率为23.90%(n=6)。不同川芎样品抗血小板聚集活性不同,4份川芎药材抗血小板聚集活性的生物效价分别为3.183、2.068、1.957和1.931 U/g,川芎饮片及川芎酒炙饮片抗血小板聚集活性的生物效价分别为1.304、1.021 U/g,速效救心丸和乐脉颗粒抗血小板聚集活性的生物效价分别为0.506、0.919 U/g。结论建立的方法可准确测定川芎药材、饮片及含川芎中成药的抗血小板聚集活性,可用来评价川芎产品的质量。     

Efficacy of Maitland joint mobilization technique on pain intensity,mouth opening,functional limitation,kinesiophobia, sleep quality and quality of life in temporomandibular joint dysfunction following bilateral cervicofacial burns

BackgroundBilateral cervicofacial burn contracture initially affects facial expressions and later affects tempero mandibular joint (TMJ) function of the patient. It further tightens the ligaments and capsules around the TMJ and leads to tempero mandibular dysfunction. The consequences of temporomandibular joint dysfunction will be pain, limitation of mouth opening, functional disability and poor quality of life (Qol). However, studies examining the efficacy of Maitland joint mobilization technique in this population are lacking.ObjectivesTo find the short term effects of Maitland joint mobilization technique on pain, mouth opening, functional limitation, kinesiophobia, sleep quality and Quality of life in tempero mandibular joint dysfunction following bilateral cervicofacial burns.MethodsThirty subjects with temporomandibular joint dysfunction following cervicofacial burn (N = 30) were allocated to Maitland joint mobilization group (n = 15) and home based training group (n = 15) randomly to receive Maitland joint mobilization technique and home based training for 4 weeks. All the participants received ultrasound therapy as common treatment. Primary (Numeric Pain Rating Scale – NPRS, maximal mouth opening – MMO & Tempero mandibular disability index – TDI) and secondary (Tampa Scale of Kinesiophobia – TSK-17, Sleep quality questionnaire – SSQ & Global Rating of Change – GRC) outcome measures were measured at baseline, after four weeks and three months follow up. Repeated measures of ANOVA and independent t test were performed for analyzing the dependent variables in both groups.ResultsBaseline demographic characters and study variables show homogenous distribution between the groups (p > 0.05). Four weeks following different training protocols Maitland joint mobilization group shows more significant changes in pain intensity, mouth opening, functional limitation, kinesiophobia, sleep quality and Qol than home based training group (p ≤ 0.05). Also Maitland joint mobilization group show significant improvement in study variables than home based training group (p ≤ 0.05) at three months follow up.ConclusionBoth groups improved over time, however, differences between the groups were noticed small. However, physiotherapy management which includes Maitland joint mobilization technique and therapeutic exercise program has an effective strategy in the treatment of tempero mandibular joint dysfunction following cervicofacial burns.
