Exploration on medication patterns of “External Treatment” in the ancient Chinese medical book Liu Juanzi Guiyi Fang

Background:To obtain the medication patterns of“External Treatment”by analyzing the prescriptions for the“External Treatment”in a Chinese ancient book called Liu Juanzi Guiyi Fang(Liu Juanzi’Ghost-Bequeathed Prescriptions,written by Liu Juanzi in 499 C.E.).Methods:The prescriptions for“External Treatment”and primary traditional Chinese medicines in Liu Juanzi’Ghost-Bequeathed Prescriptions were analyzed using data mining methods,such as frequency analysis and cluster analysis,after screening for prescriptions related to“External Treatment”in Liu Juanzi’Ghost-Bequeathed Prescriptions.The Database of Prescriptions for External Treatment in Liu Juanzi Guiyi Fang was then established.Results:The earliest Chinese characters for“Yin”and“Yang”were found on“oracle bones”.These bones were the skeletal remains of different animals,and were used in ancient Chinese divination practices going all the way back to the 14th century B.C.Simply put,“Yin”is the cold and“Yang”is the warm.In traditional Chinese medicine,this concept of dualism and its fundamental principle underlie physiology,pathology,and the treatment of illnesses.The“External Treatment”discussed in Liu Juanzi’Ghost-Bequeathed Prescriptions primarily adopts the methods of“Warming Yang”,“Cooling Heat(Yang)”,and“Qu Xie(dispelling pathogenic factors of epidemic diseases)”,as well as“Huo Xue(promoting blood circulation)and promoting tissue regeneration.In Chinese medicine,“Si Qi(cold as winter,cool as autumn,warm as spring,hot as summer)”,“Wu Wei(five flavors:sweet,pungent,salty,sour,and bitter)”used to describe the properties of herbs.In Liu Juanzi’Ghost-Bequeathed Prescriptions,most of the medicines used were more“Sweet”,“Pungent”,“Warm”,and the“Channel Tropism”were primarily distribute to the“Liver”,“Heart”,“Stomach”,and“Large intestine meridian”.Conclusion:The data mining method systematically summarized the medication characteristics of the prescriptions for“External Treatment”in Liu Juanzi’Ghost-Bequeathed Prescriptions.The characteristics of the“External Treatment”in this book include“supporting healthy Qi”and“promoting Qi and Blood circulation”which as the top priority,applying both“Attacking and Supplementing methods”as the focus,and combining“Supplementing methods”with“Elimination methods”.It has provided theoretical guidance in“External Treatment”for surgery of traditional Chinese medicine.

Study on Yan-Xin Wang’s medication experience and regularity in treating Insomnia from the liver based on data mining

Background:Professor Yan-Xin Wang has been committed to the use of traditional Chinese medicine formulas to treat insomnia from the liver for many years,and has achieved excellent clinical results.In order to better inherit Yan-Xin Wang’s academic thoughts.The purpose of this study is to use clinical data to explore the clinical experience of Prof.Yan-Xin Wang in the application of Chinese medicine to treat insomnia patients from the liver,explore the compatibility and medication rules of traditional Chinese medicine,and give more clinical treatment ideas for insomnia.Methods:The general data and prescription information of insomnia patients treated with Chinese herbal medicine by Prof.Yan-Xin Wang from January 1,2021,to December 31,2021,were summarized according to the inclusion and exclusion criteria,and the data were subjected to frequency statistics and drug association rules,complex network diagram analysis and cluster analysis.Results:A total of 159 patients and prescriptions were included in the study,of which 81.1%were women and 18.9%were men,containing 128 herbs;the highest frequency of use was 91.8%for Bupleuri Radix.Six Chinese herbs were used more than 70%of the time,namely Bupleuri Radix,Scutellariae Radix,oyster shell,Glycyrrhizae Radix,Os Draconis,and Ziziphi Spinosae Semen.The top 20 herbs in terms of frequency of use were analyzed in terms of the four Qi,five flavours,and their attributions.The four Qi were mainly calm and warm,the five flavours were mainly bitter and acrid,followed by sweet,and the attributions were mainly to the liver,spleen,and heart meridians.The Chinese medicine association rules set the confidence level>80%and the support level>10%,resulting in 10 two-herb and three-herb associations with the highest confidence level,such as Os Draconis is associated with oyster shell,Platycodonis Radix is associated with Achyranthis Bidentatae Radix,Scutellariae Radix is associated with Bupleuri Radix,Os Draconis,Bupleuri Radix is associated with oyster shell,Os Draconis,Scutellariae Radix is associated with oyster shell,etc.Cluster analysis yielded 3 classes of drug formulas.The complex network diagram shows that the core prescription drugs are composed of Bupleuri Radix,Chuanxiong Rhizoma,Pseudostellariae Radix,Jujubae Fructus,Os Draconis,Coptidis Rhizoma,Scutellariae Radix,Ziziphi Spinosae Semen,Smilacis Glabrae Rhizoma,Cinnamomi Cortex,White Moutan Cortex,Atractylodis Rhizoma,Glycyrrhizae Radix,oyster shell,Rehmanniae Radix Praeparata,Tritici Levis Fructus,Pinelliae Rhizoma Praeparatum,and Cinnamomi Ramulus.Conclusion:Prof.Yan-Xin Wang believes that the main treatment for patients with insomnia is based on the liver,by tonifying the deficiency and supporting the righteousness,mutually regulating the liver and spleen,and calming the mind and nourishing the heart,while adding and subtracting appropriate herbs according to the patient’s co-morbidities,which can significantly improve the patient’s insomnia symptoms.

新型冠状病毒肺炎患者中医药用药规律分析

目的:描述中医药(traditional Chinese medicine,TCM)用于新型冠状病毒肺炎(COVID-19)患者治疗的临床用药规律。方法:将接受中医药治疗的成年COVID-19患者根据入院时临床分型合并为非严重型组(轻型和普通型)和严重型组(重型和危重型)。通过调查患者的病历和用药记录,描述其中医药使用情况和用药模式。结果:共纳入3872例新冠肺炎患者。总体患者中,口服中成药(CPM)是最常用的中药种类,其次是方剂汤药;联合用药比例高于药物单用(55.0%vs.45.0%),方剂汤药联用口服CPM为最常见的联用模式(39.1%,1514/3872)。两组不同入院病情患者中,严重型组患者口服、注射、外用CPM使用较非重症组多见,非严重型组以方剂汤药、非药物中医药治疗较严重型组多见;两组患者均以多药联用为主,均以方剂汤药联用口服CPM最常见。将严重型患者按预后及结局分为三组,注射CPM在病情不断进展最终死亡患者组中使用比例较高(35.0%,36/103);两组最终出院患者最常见的两种用药模式分别为汤剂联用口服CPM和单用口服CPM,最终死亡患者中则为口服CPM及其与注射CPM联用;三组患者在中医药使用比例及用药模式上存在显著差异。结论:本研究发现的COVID-19患者常用的中医药治疗措施及用药模式有待进一步探索,以期为COVID-19治疗提供更完整的参考。
