The electrical characteristics of meridians and acupoints have been being one of the hot topics discussed by scholars, because of many influencing factors and inconsistent research results. In the present article, we collected papers published in Chinese or English in recent 10 years from PubMed, CNKI, and VIP databases by using key words of"acupuncture""meridian""resistance""capacitance""electrodermal"and"impedance". Then, we make an analysis about its development from three aspects, 1) manifestations of electrical properties of acupoints (low dermal resistance under pathological state, imbalance between left and right sides of the synonym acupoints), 2) clinical application of acupoint electrical characteristics for diagnosis of clinical disorders and evaluation of therapeutic effect, and 3) current situations of development of meridian detection instruments based on electrical characteristics (improving stability of instruments，expansion of the detected regions and measuring time, realization of visualization, and operational automation). In the process of coming studies, we highly recommend that more attention should be paid to the acupoints' "dynamic changes"， and forming a standardized research plan, strengthening domestic and international academic exchanges and cooperation are definitely necessary in order to validate the objectivity and specificity of electrical characteristics of meridians and acupoints, further expanding its clinical application.

新型冠状病毒肺炎简称"新冠肺炎",达到出院标准的患者逐渐增多,恢复期患者的康复治疗应受到重视.通过查阅古今中外文献发现,刮痧疗法治疗瘟疫历史悠久,疗效确切.近年来的临床研究也表明刮痧治疗感染后咳嗽、失眠、乏力等疾病疗效显著.现代研究表明,刮痧能通过调节肌体免疫及抗氧化来达到防治疾病的目的.笔者对刮痧干预新冠肺炎恢复期的理论基础进行了分析并对下一时期的工作提出了建议,以期能进一步推广刮痧疗法,作为中医抗疫的有效补充手段.

Objective:to evaluate the clinical efficacy ofGua Sha (scraping) in the treatment of cough after a cold.Methods:According to the clinical randomized control principle,72 patients with cough after a cold were randomly divided into guasha group and sham guasha group,36 cases in each group.Both groups were scraped on DU meridian on the back,the first lateral line of the bladder meridian of foot-taiyang on the back,the inside of upper limbs of the lung meridian of hand-taiyin,LU 2 (yún mén),LU 1 (zhōng fǔ),RN 17 (dàn zhōng),and LI 4 (hé gǔ).Guasha group scraped sha (rash-like spots) while sham guasha group scraped until the skin got red without sha.The treatment was performed two times,once a week.Compare the coughing integral changes and total effective rates of two times before and after treatment respectively.Results:The coughing integrals of both groups of two times decreased after treatment,P ＜ 0.05 of intra group comparison,and P ＜ 0.05 of comparison between groups;after the 2nd treatment,the total effective rate ofguasha group was 94.4％,sham group 66.7％;the difference was significant (P ＜0.05).Conclusion:Gua Sha can obviously reduce the integral of cough after a cold and the curative effect is remarkable.

Tian Shuxiao was one of the 12 Famous Chinese medicine experts of Hebei province and the mentor of the third and fourth batch of the old Chinese medicine expert academic experience of inheritance.She was good at treating gynecological diseases in clinical practice,and in the treatment,she has developed unique treatment and drug characteristics.Endometrial hyperplasia of about 50％ occur in the menopausal transition.Simple endometrial hyperplasia clinical manifestation for perimenopausal menstrual blood volume increases or continuing after menstruation,from the clinical manifestations of the disease belongs to the category of TCM metrorrhagia and metrostaxis.According to the occurrence of the disease is due to endometrial hyperplasia,hyperplasia in accumulation or zhengjia of traditional Chinese medicine,so tian thought that besides belong metrorrhagia and metrostaxis,should also be in the category of zhengjia.Tian thinks treatment should treating metrorrhagia and metrostaxis,at the same time give consideration to resolving hard masso In order to provide a reference for the clinical treatment of the disease and medication,we were summing up the unique experience of Tian Shuxiao,combination to organize the methods of softening and resolving hard mass,upraise yuanq to treat metrorrhagia and metrostaxisi and adjust the habitus of Yin and Yang

Objective: to observe the functional status of partial mast cells before and after scraping so as to reveal the functional mechanism of Guasha therapy.Methods: The normal Wistar rats were randomly divided into pre-scraping group, instant group after scraping, 30 min group, 60 min group, and 90 min group, 10 rats each group.Except pre-scraping group, all the others were intervened with Guasha, scraping Du meridian and Bladder meridians, 60 times /min, for 30 seconds each time.The rats of each group were killed off before scraping, and instantly, 30 min, 60min and 90 min after scraping respectively, materials taken from the most obvious part of one Bladder meridian.Toluidine blue staining and Immunohistochemical tests were used to observe the number of mast cells, degranulations and tryptase expression.Results: there was no significant difference between the numbers of mast cells, P>0.05;degranulation rates of each group had no significant difference, P>0.05;there was no significant difference between numbers of positive tryptase, P>0.05.Conclusion: the functional status of mast cells has no obvious changes instantly after scraping and 90 min after scraping, that is, Guasha does not affect the partial mast cells in normal rats instantly after scraping.It therefore can be predicted that the instant effect of Guasha therapy is irrelative to mast cells.

目的：通过对近30年针灸治疗感冒后咳嗽临床研究文献计量学分析，从临床研究方法、治疗方法选择、穴位选择等方面为针灸治疗感冒后咳嗽临床研究提供借鉴。方法：采用相关主题词，严格按照纳入标准和排除标准，从中国期刊全文数据库（ CNKI）、维普中文科技期刊数据库（ VIP）检索1987年至2016年针灸治疗感冒后咳嗽相关文献，并用文献计量学方法对其进行定量分析。结果：符合纳入标准的文献共57篇，从研究方法看，23篇运用对照研究，其中18篇为随机对照研究，5篇描述了随机方法，未见运用盲法的文献；从疗效来看，57篇文献报道的平均有效率为94．5％；从刺灸方法来看，使用频次最高的为针刺、拔罐；从腧穴选用来看，使用频次较高的为背部膀胱经腧穴，其中肺俞穴使用最多。结论：针灸治疗感冒后咳嗽多采用膀胱经腧穴，主要方法为针刺和拔罐，有效率较高，但临床研究设计不够规范，需进一步扩大样本量，规范设计，提高临床研究水平，为针灸治疗感冒后咳嗽提供确凿证据。
