基于文献计量学探讨合谷穴的敏化现象与规律

The sensitization phenomena and regularity of Hegu(LI 4) based on bibliometrics

初步探索合谷穴的敏化现象与规律。通过计算机检索Cochrane Library、PubMed、Embase(OvidSP)、中国期刊全文数据库(CNKI)、中国生物医学文献数据库(CBM)、维普(VIP)和万方(WF)数据库,并结合手工检索,收集合谷穴敏化相关文献,建立合谷穴敏化现代文献数据库,采集疾病种类、敏化类型、检测方法、检测指标等相关信息,应用频次统计进行分析。最终纳入文献47篇,其中热敏最多,疾病类型以肝胆、肢体经络、肺系、脾胃病证多见。各敏化现象检测方式多样,其中痛敏多用钾离子导入法、热水甩尾测痛法等,电敏多用腧穴电阻测定仪,热敏多用红外热像仪,光敏用红外光谱分析仪,压敏用压痛测试仪。检测指标亦不同,痛敏检测痛阈,电敏多检测穴位电阻,热敏多检测温度,光敏检测红外辐射平均尖锐程度、平均能量,压敏检测压痛阈。合谷穴敏化涉及热敏、电敏、痛敏、压敏、光敏5种敏化类型。其中合谷穴敏化现象常见于面瘫、支气管哮喘、变应性鼻炎、耳鸣、溃疡性结肠炎等疾病。疾病状态下,合谷穴位温度、痛阈值、压痛阈值及红外辐射平均尖锐程度、平均能量均低于健康受试对象;电阻值高于健康受试对象。

The sensitization phenomena and regularities of Hegu(LI 4) were preliminarily explored. The relevant literature regarding Hegu(LI 4) sensitization were collected by computer retrieval at Cochrane Library, Pubmed, Embase(OvidSP), China Journal Full Text Database(CNKI), China Biomedical Literature Database(CBM), VIP and Wanfang(WF) databases as well as manual searching, and a modern literature database of Hegu(LI 4) sensitization was established. The information of disease type,sensitization type, detection method and index were collected. Frequency statistics method was used for analysis. As a result, 47 literatures were included, of which heat sensitivity was the most common type of sensitization, and diseases of liver and gallbladder, limb meridians, lung system, and spleen-stomach system were the most common types of diseases. The detection method of sensitization was various, among them, potassium ion introduction method and hot-water tail-flick method were mainly used for pain sensitivity, while acupoint resistance measuring instrument was mainly used for electric sensitivity, while thermal infrared imager was mainly used for heat sensitivity, while infrared spectrometric analyzer was mainly used for light sensitivity,while pressing pain measuring instrument was used for pressing sensitivity. Detection index was different, pain sensitivity detected pain threshold, electric sensitivity mainly detected acupoint resistance, heat sensitivity mainly detected temperature,light sensitivity detected average sharpness and average energy of infrared radiation, pressing sensitivity detected pressing-pain threshold. In conclusion, the regularities of sensitization of Hegu(LI 4) were preliminarily summarized, which involved five sensitization types: heat sensitivity, electric sensitivity, pain sensitivity, pressing sensitivity and light sensitivity. The sensitization of Hegu(LI 4) was commonly seen in facial paralysis, bronchial asthma, allergic rhinitis, tinnitus, ulcerative colitis. The temperature, pain threshold, pressing-pain threshold, average sharpness and average energy of infrared radiation of Hegu(LI 4) in pathological condition were lower than those in healthy subjects, and the resistance value was higher than that of healthy subjects.
