Objective: To study the mechanism and effects of different scraping techniques on body surface blood perfusion volume and local skin temperature of healthy subjects and to provide a baseline for microcirculation and energy metabolism for the evaluation of the therapeutic effects of scraping. Methods: Changes of the local blood perfusion volume and skin temperature of healthy subjects before and after applying different scraping techniques were observed with a laser Doppler imager combined with an infrared thermographic device and the resulting data was analyzed with imaging and processing software for statistical analysis. Results: Local blood perfusion volume and skin temperature all increased after both reinforcing and reducing scraping techniques. The value of blood flow 60 and 90 min after the reducing technique was significantly higher than that after the reinforcing technique (P<0.01), while the skin temperature increased after both techniques but was not significantly different between the two (P>0.05). Conclusion: Scraping can significantly improve the local blood perfusion volume, increase skin temperature and promote local blood circulation and metabolism of tissues.
OBJECTIVE:To explore factors influencing the curative effect of scraping therapies (at acupoints or along channels) and to determine the relationship of scraping site and strength to curative effect. METHODS: Two hundred and ten patients with lumbar muscle strain were divided into five groups with 42 patients each.The "scraping therapy at acupoint until appearance of skin eruptions" and "scraping therapy along channel until appearance of skin eruptions" groups were treated with a 4-daycourse. The "scraping therapy at acupoint without appearance of skin eruptions", "scraping therapy along channel without appearance of skin eruptions", and acupuncture groups were treated with a 2-day course.The five groups were treated with seven courses. The visual analog scale (VAS), oswestry disability index (ODI), and lumbago scores were recorded in the five groups before treatment, after each treatment, and in follow-up visits one month and three months after treatment. RESULTS: VAS, ODI, and lumbago scores after treatment improved in the five groups (P<0.01). There was a statistical difference (P<0.01) in the change of VAS scores by appearance of skin eruptions and scraping site. CONCLUSION: Scraping therapy can effectively alleviate lumbago symptoms. The appearance of skin eruptions and scraping therapy along channels can enhance the curative effect of scraping therapy.

Objective To observe the antihypertensive efficacy of guasha for essential hypertension.Methods Thirty-four cases of essential hypertension were treated with guasha along the following route of the governor vessel,the bladder meridian and the gallbladder meridian and the hand yangming large intestine meridian and the foot yangming stomach meridian on the head,neck and back.The gentle stimulation and supplementation method was applied for deficiency syndrome and the heavy stimulation and drainage method was applied for excess syndrome.Two times a week,total 8 treatments were given Blood pressure was measured at different time points from2：00PM to 8：00PM（2：00PM,2：30PM,3：00PM,3：30PM,4：00PM,5：00PM,6：00PM,8：00PM） before the first application of guasha and after the eighth treatment,respectively.Results Compared with each time point before the first application of guasha,there were statistically significant differences of blood pressure at each corresponding time point after the eighth guasha（all P〈0.01）.Blood pressure reduced from（147.42 ± 13.04） /（86.27 ± 11.91） mmHg to（129.35 ± 9.16） /（80.15 ± 9.41） mmHg;the score of grading and quantifying of TCM pattern significantly decreased（P〈0.01）.The score of quality of life scale of Duchenne hypertension significantly increased（P〈0.01）.Conclusion Blood pressure can be effectively reduced by adopting guasha,and the clinical symptoms and quality of life of patients with essential hypertension can be improved.
目的:观察"出痧"刮痧、"不出痧"刮痧与针刺治疗慢性非特异性下腰痛(NLBP)的临床疗效差异。方法:通过中央网络随机分组系统,将150例符合纳入标准的NLBP患者随机分为出痧组、不出痧组和针刺组,每组50例。出痧组在受试者腰部(肾俞、志室到次髎、秩边)、下肢(从承扶过委中至承山)进行刮痧,每个部位刮8-10次,并且要求"刮致出痧",每次刮痧治疗间隔4d,总共治疗7次。不出痧组操作方法与出痧组相同,但要求"不出痧",每次刮痧治疗间隔2d,总共治疗7次。针刺组针刺患者肾俞和委中,直刺进针,施平补平泻手法至局部出现酸麻肿重感,每次治疗30min,每次针刺间隔2d,总共治疗7次。比较3组受试者治疗前、治疗结束后及1个月与3个月的随访时视觉模拟量表(VAS)、自拟临床症状积分和Oswetery功能障碍指数(ODI)。根据M5P决策树算法,使用Weka Explorer 3.6软件计算刮痧治疗NLBP疗效预测方程。结果:1治疗结束时,出痧组脱落7例,不出痧组脱落6例,针刺组脱落8例,最终完成129例。3组受试者在治疗过程中未发生不良反应。2治疗结束后,3组NLBP患者VAS、临床症状积分、ODI指数均明显降低(P<0.05),且随访1个月、3个月随访疗效稳定;出痧组3个指标的改善均优于不出痧组和针刺组,针刺组3个指标的改善亦优于不出痧组(均P<0.05)。3根据M5P决策树算法,提出刮痧治疗NLBP疗效预测方程,且使用ODI作为因变量方程拟合度较高。结论:刮痧治疗NLBP疗效明显,安全性高,且中短期疗效优于"不出痧"刮痧和针刺治疗,表明刮痧"出痧"是临床疗效的重要影响因素;同时ODI可以作为刮痧治疗腰痛的敏感指标之一。
