Observation on Clinical Efficacy and Safety of Xiaoyu Ointment for External Use Combined with Hydro-acupoint Manipulations for Relieving Swelling in the Treatment of Acute Soft Tissue Injury
Objective To explore the clinical efficacy of focal external application of Xiaoyu Ointment(mainly composed of wine-processed Rhei Radix et Rhizoma,Taraxaci Herba,Lonicerae Japonicae Flos,Paeoniae Radix Rubra,Curcumae Longae Rhizoma,vinegar-processed Cyperi Rhizoma,Gardeniae Fructus,Angelicae Dahuricae Radix,Angelicae Sinensis Radix,Menthae Haplocalycis Herba,and Notopterygii Rhizoma et Radix)combined with manipulations for relieving swelling on hydro-acupoints of Yinlingquan(SP9),Chize(LU5),Quchi(LI11)and Ashi points around the injury site for the treatment of acute soft tissue injury.Methods A total of 136 patients with acute soft tissue injury were randomly divided into treatment group and control group,with 68 cases in each group.The control group was treated with topical application of Loxoprofen Sodium Gel,and the treatment group was treated with topical application of Xiaoyu Ointment combined with manipulations for relieving swelling on hydro-acupoints.Five days constituted a course of treatment,and the treatment lasted for 2 courses.The changes of visual analogue scale(VAS)score of pain degree,scores of primary symptoms of degree of swelling,degree of activity limitation and pain duration,and the overall scores of traditional Chinese medicine(TCM)syndromes in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 2 courses of treatment,the total effective rate of the treatment group was 94.12%(64/68)and that of the control group was 91.18%(62/68).There was no significant difference of the total effective rate(by chi-square test)between the two groups(P>0.05),but the overall efficacy of the treatment group(tested by rank sum test)was significantly superior to that of the control group(P<0.05).(2)After treatment,the VAS scores of pain degree in the two groups were significantly lower than those before treatment(P<0.01),and the decrease in the treatment group was significantly superior to that in the control group,the difference being significant(P<0.01).(3)After treatment,the scores of degree of swelling,degree of activity limitation and pain duration in the two groups were significantly decreased when compared with those before treatment(P<0.01),and the decrease in the treatment group was superior to that in the control group,the differences being significant(P<0.05 or P<0.01).(4)After treatment,the overall scores of TCM syndromes in the two groups were significantly decreased when compared with those before treatment(P<0.01),but there was no significant difference between the two groups after treatment(P>0.05).(5)During the treatment period,there was no obvious adverse reaction occurring in the treatment group.In the control group,2 patients had skin flushing and itching in the medicated region,which disappeared after drug withdrawal.Conclusion Topical application of Xiaoyu Ointment combined with manipulations for relieving swelling on hydro-acupoints is effective on alleviating swelling,relieving pain and improving joint motion of range during the treatment of acute soft tissue injury.
