龙虎交战针法对非特异性下背痛患者血浆P物质的影响

目的 观察龙虎交战针法对非特异性下背痛患者血浆P物质的影响,初步探讨其镇痛机制.方法 将90例入选患者随机分为3组,分别为龙虎交战针法组(A组)、平补平泻针法组(B组)和中频理疗组(C组),每日治疗1次,6次为1个疗程,2个疗程后统计临床疗效；检测3组治疗前后外周血浆P物质的含量.结果 治疗后临床疗效A组与B、C组比较(P＜0.05),差异有统计学意义.3组血浆P物质含量治疗前后比较,差异有统计学意义(P＜0.01),其中治疗后A组与B、C组比较,差异有统计学意义(P＜0.01),B组与C组比较,差异有统计学意义(P＜0.01),对血浆P物质含量的影响,A组优于B组,B组优于C组.结论 龙虎交战针法是治疗非特异性下背痛有效的镇痛针法之一,其镇痛机制可能与降低血浆中P物质有关.

Effects of long-hu-jiao-zhan manipulation on plasma substance P in the nonspecific low back pain patients

Objective To observe the effects of long-hu-jiao-zhan acupuncture manipulation on plasma substance P(SP) in the nonspecific low back pain patients and to study its analgesic mechanisms.Methods 90 nonspecific low back pain patients were randomly divided into 3 groups as long-hu-jiao-zhan manipulation group(Group A),reinforcing-reducing technique group(Group B) and intermediate frequency physical therapy group(Group C).Each group was treated once a day;a treatment course was 6 days.Peripheral plasma SP content was examed before and after 2 courses.Results After treatment,clinical effects of Group A had significant differences compared with the controls(P<0.01).The differences of peripheral plasma SP content among 3 groups were statistically significant before and after treatment(P<0.01);Group A had more significant changes than Group B and Group C(P<0.01);the difference between Group B and C had statistic differences(P<0.01);the changes of Group A was greater than Group B,and the changes of Group B was greater than Group C.Conclusion Long-hu-jiao-zhan manipulation is effective.Its analgesia technique may be relevant to the reduce of peripheral plasma SP.
