基于因果模型的中医临床疗效评价方法探讨被引量:9
2008年
探索国际界认可的疗效评价方法是解决"中医药有效性"问题的关键之一,中医临床疗效评价实际上是中医辨证论治与临床结局之间是否具有因果关联的研究,而目前大多数的统计方法仅适用于相关性研究,统计得到的事物间的相关关系常常被错误地用于解释为原因与结果间的关系。因果模型是研究因果推断的一种非常重要的工具,近年来在统计学、流行病学和数据挖掘领域中,因果推断越来越受到重视。目前,有若干种因果模型,其中虚拟事实模型和贝叶斯网络模型在中医研究中应用较多。本文主要介绍、分析这两种模型的原理、构建方法,探讨其在中医临床疗效评价中的运用。

中药复方制剂防治肝癌的研究进展被引量:4
2011年
肝癌(hepatocellular carcinoma,HCC)是世界第6大肿瘤,近年来HCC发病率在欧洲和美国呈上升趋势,我国为高发区。中医药防治HCC是我国治疗HCC的特色和优势,近年来复方中药制剂对HCC细胞的直接抑制,对细胞凋亡的影响,以及在提高机体免疫力等方面的分子机制研究进展迅速;复方中药制剂预防和治疗HCC的临床疗效观察研究也取得了一定的进展,现将近5年中药复方制剂防治HCC的研究进展做一综述,为提高中医药防治肿瘤的疗效提供参考。

中药治疗方案对肝癌术后复发的影响因素初步分析被引量:8
2011年
目的:观察原发性肝癌患者术后可能影响肝癌复发的因素及中药序贯治疗、肝动脉化疗栓塞(TACE)治疗肝癌患者的效果。方法:采用回顾性研究,对127例原发性肝癌根治术后使用华蟾素注射液序贯治疗的患者与同期82例肝癌根治术后采用TACE术预防复发/转移的患者进行对比分析,观察其复发/转移时间后,对可能的影响因素,如年龄、性别、肿瘤大小和肝功能分级等情况进行分层分析。结果:华蟾素治疗组和西医治疗组患者年龄分布上差异有统计学意义,其他一般资料差异无统计学意义。性别、年龄等分层后发现,华蟾素治疗组和西医治疗组生存期有明显差异。按肿瘤大小分层后,小肝癌(肿瘤直径≤3 cm)时,患者复发/转移曲线在大约18个月存在交差,而后逐渐分离,华蟾素治疗组患者复发时间延长。结论:从回顾性分析来看,原发性肝癌根治术后序贯使用华蟾素注射液抗肿瘤治疗,与患者年龄、性别等因素关系不大。

三种抗肿瘤中药有效成分对人脐静脉内皮细胞生长的影响被引量:8
2011年
目的探讨蜂毒素、去甲斑蝥素、蟾毒灵3种抗肿瘤中药提取物的抗血管生成作用,并检测其量效关系,比较其抑制血管生成所需浓度与抑瘤浓度的关系。方法采用四甲基偶氮唑蓝(MTT)法测定3种药物在不同浓度、时间对人肝癌细胞ECV304生长的抑制作用,计算半数抑制浓度(IC50),观察量效、时效关系。结果 3种药物对ECV304细胞的生长有不同程度抑制作用(P<0.05或P<0.01),且呈浓度和时间的依赖性。蜂毒素在24、48和72h抑制ECV304细胞的IC50分别为7.64、4.25和2.64μg/ml,去甲斑蝥素为271.52、108.83和80.76μg/ml,蟾毒灵为1.104、0.355和0.0905μg/ml。结论蜂毒素、去甲斑蝥素、蟾毒灵有明确的抑制血管内皮细胞增殖、抗血管生成的作用。

Preventive Effects of Jiedu Granules(解毒颗粒) Combined with Cinobufacini Injection(华蟾素注射液) versus Transcatheter Arterial Chemoembolization in Post-Surgical Patients with Hepatocellular Carcinoma:A Case-Control Trial被引量:16
2012年
Objective:To investigate the therapeutic effects of Jiedu Granules(解毒颗粒),a Chinese medicine(CM) compound,plus Cinobufacini Injection(华蟾素注射液),which was extracted from skin of Bufo bufo gargarizans Cantor,to prevent the recurrence of hepatocellular carcinoma(HCC) after surgical resection. Methods:In this case-control trial,a total of 120 patients who stayed in Changhai Hospital were enrolled from December 2001 to December 2006.Sixty patients were treated with Jiedu Granules plus Cinobufacini Injection to prevent tumor recurrence after operation(CM group) and 60 patients were treated with transcatheter arterial chemoembolization(TACE) after operation(TACE group).Progression-free survival(PFS) and overall survival (OS) rates were determined to evaluate the therapeutic effects of post-operative management of patients with HCC.Results:PFS in the CM group was 18.07 months[95%confidence interval(CI):12.49-23.65]and the 1-,2-,3-,4-and 5-year PFS rates were 61%,39%,26%,22%and 12%,respectively.PFS in the TACE group was 8.03 months(95%CI:6.63-9.44) and the 1-,2-,3-,4-and 5-year PFS rates were 34%,11%,7%,2%and 0%,respectively.There was significant difference in survival rate between the two groups(P<0.01).The mean survival time(MST) of patients in the CM group was 49.53 months versus 39.90 months of the TACE group.The 1-,2-,3-,4-and 5-year survival rates were 90%,82%,80%,70%and 63%,respectively,in the CM group,and 79%,70%,60%,60%and 36%,respectively,in the TACE group.There was significant difference in survival time between the two groups(P=0.045).Conclusions:Jiedu Granules plus Cinobufacini Injection,a combination that is commonly used for post-operation management of HCC,can postpone tumor recurrence and metastasis, prolong the survival time and increase the survival rate of post-surgical patients with HCC.However,these findings need to be confirmed in a prospective,randomized controlled trial.

A traditional Chinese herbal medicine compound preparation versus interventional therapy after resection of small hepatocellular carcinoma:22-year follow-up被引量:8
2012年
OBJECTIVE:To compare the long-term effectiveness of compound Ruanjianhugan(RJH)tablets and interventional therapy(IT) in patients after resection of small hepatocellular carcinoma(HCC).METHODS:A retrospective study was conducted in 399 patients after resection of small HCC who were admitted between January 1987 and December 2008 in the Department of Hepatobiliary Surgery and Center of Minimlly Invasive Surgery,First Affiliated Hospital of Guangxi Medical University.Four groups were based on different therapy modes:a TCM-only(TCMO) group,a TCM combined with interventional therapy(TCM-IT) group,an interventional therapy-only(ITO) group,and a simple operation(SO) group.Prognostic factors were correlated with overall survival(OS) and OS rates were calculated with the Kaplan-Meier method,and multivariate analyses for factors affecting survival were evaluated by the Cox proportional hazard model.RESULTS:The median OS was 151.20 months in the TCM-IT group,43.87 months in the ITO group,and 20.77 months in the SO group.All survival rates of the TCMO group were higher than those of the other three groups(>50%).The 5-,10-,and 15-year OS in the TCMO and ITO patients were 83.94%,45.50%,and 71.22% and 33.34%,55.58%,and 9.26%,respectively(risk ratio,0.209;95% confidence interval,0.126-0.347;P=0.000).Multivariate analysis revealed that the independent risk factors were therapy mode(P=0.000),sex(P=0.005),family history(P=0.011),TNM Classification of Malignant Tumor staging(P=0.000),medical care-seeking behavior(P=0.021),and maximum diameter(P=0.030).CONCLUSION:Long-term oral use of compound RJH tablets may improve OS for small HCC after resection compared with IT.
