Objective To observe the efficacy of scalp acupuncture combined with oral administration of ènì Tāng(呃逆汤, Hiccup Decoction) for treatment of intractable hiccup. Methods One hundred patients with intractable hiccup were divided into treatment group(acupuncture combined with herb decoction group) and control group(western medicine group) according to the random number table method with 50 patients in each group. In treatment group, scalp acupuncture was conducted in the gastric area and thoracic area of patients, and Hiccup Decoction was taken orally. In control group, anisodamine(654-2) was injected intramuscularly in the dosage of l0 mg. The treatment was conducted for once a day in each group, and treatment for three consecutive times was needed. The number of times and the frequency of hiccup were observed after each treatment, and the results were compared. The standard of therapeutic effectiveness was evaluated by the number of hiccups decreased. Results In treatment group, the total cure rate was 54%, and the total effective rate was 84%, in control group, the total cure rate was 32%, and the total effective rate was 66%. According to the comparison between the two groups in the cure rate and total effective rate, the differences were statistically significant(both P〈0.05). After the first treatment, there was no statistical difference according to the comparison between the two groups in the cure rate and total effective rate(both P〈0.05), after the second treatment, the differences were statistically significant according to the comparison between the two groups in the cure rate and total effective rate(both P〈0.05), and the efficacy in treatment group was obviously superior to that in control group, after the third treatment, there was no statistical difference according to the comparison between the two groups in the cure rate and total effective rate(both P〈0.05). Conclusion In the one course of treatment, the efficacy of acupuncture combined with herb decoction for treatment of intractable hiccup was obviously superior to that of intramuscular injection with anisodamine. The therapeutic effect of intramuscular injection with anisodamine for treatment of intractable hiccup was the best at the first treatment, and the therapeutic effect of acupuncture combined with herb decoction was the best at the second treatment. 展开更多

Objective:To observe the differences of clinical efficacy of intractable lumbodynia after lumbar disc herniation surgery treated by pestle needling at Yāoyángguān Bāzhèn points,electroacupuncture and western medication.Methods:A total of 210 patients with intractable lumbodynia after lumbar disc herniation were randomly divided into pestle needle group,electroacupuncture group and western medication group,with 70 cases in each group.The pestle needle group was treated with pestle needle poking Yāoyángguān-Bāzhèn(GV3-Bāzhèn)points.The electroacupuncture group was treated with conventional electroacupuncture,and the western medication group was treated with oral diclofenac sodium dual release enteric-coated capsules(Difene).The pestle needle group and the electroacupuncture group were treated once a day,and there was 1 day of rest after 6 days of treatment,and a course of treatment included 7 days,and a total of 3 courses of treatment were performed.The western medication group took 1 Difene capsule(75 mg)at a time,with once a day continuing for 21 days.Visual Analog Scale(VAS),Pain Rating Index(PRI)and Present Pain Intensity(PPI)were used to observe the improvement of pain before and after treatment,and the waist muscle tone was examined and the clinical efficacy was observed.Results:The post-treatment VAS,PRI,and PPI scores of the three groups were all lower than pretreatment,and the differences were statistically significant(all P<0.05).There were no statistically significant differences in VAS,PRI and PPI scores between pestle needle group and western medication group(all P>0.05).Meanwhile,they were all lower than the electroacupuncture group,and the differences were statistically significant(both P<0.05).After treatment,the waist muscle tone of the three groups was higher than that pre-treatment,and the differences were statistically significant(all P<0.05).After treatment,the waist muscle tone of the pestle needle group was higher than the electroacupuncture group,and the electroacupuncture group was higher than the western medication group,and the differences were statistically significant(both P<0.05).The total effective rate was 88.57%in the pestle needle group,80%in the electroacupuncture group,and 77.14%in the western medication group,and there were no statistically significant differences among the groups(P>0.05).Conclusions:Pestle needle poking GV3-Bāzhèn points can effectively relieve intractable lumbodynia after lumbar disc herniation surgery,decrease VAS,PRI,PPI scores and relieve waist muscle tone,and the effect was remarkable. 展开更多
