RESUMO
Objective:It was a part of an overall study of the clinical research literature about ischemic cerebrovascular disease treated by various acupuncture techniques,namely "restoring consciousness and inducing resuscitation technique","needling Baihui(DU20) through Qubin(GB7)","Jiao’s three-needle technique" and "temporal three-needle technique".The papers collection for analysis were designed on the random,control and blind methods.Methods: A data bank was set up with Access 2003.A statistical analysis was made for the method of employing ratio and constituent ratio about the research literature mamaged with the ramdom,control and blind methods.Results: The ratio of those that were designed randomly is as follows: the "restoring consciousness and inducing resuscitation technique"(50%),"needling Baihui(DU20) through Qubin(GB7)"(100%)(Only two articles meet the request and futher exploration is needed),and the "temporal three-needle technique"(50%).And the "Jiao’s three-needle technique"(40%).The ratio of those that were designed with the control method is as follows: the "restoring consciousness and inducing resuscitation technique"(60%),"needling Baihui(DU20) through Qubin(GB7)"(100%)(Only two articles meet the request and further exploration is needed,the "temporal three-needle technique"(75%),and "Jiao’s three-needle technique"(70%).The blind method was not used.Conclusion: It is suggested that the three methods should be stressed in the study of acupuncture in the treatment of ischemic cerebrocvascular disease.Only in this way,can there be a maximum comparability and the sampling error is decreased.The bias due to subjective factors of the researchers and subjects can be overcome.
