Objective To analyze the volatile constituents of Linglingxiang (Lysimachia foenumgraecum,Hance,Holy Basil) by applying solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC/MS).Methods The heads of solid phase microextraction (SPME) with 4 kinds of different coating,75 μm CAR/PDMS,65 μm DVB/PDMS,85 μm PA and 100 μm PDMS,were used to extract the under the best extraction condition,and then these volatile constituents were detected by using gas chromatography-mass spectrometry (GC-MS).Results The key parameters of SPME for extracting volatile constituents from Linglingxiang were as follows:temperature was 85℃C and extracting time was for 50 min.A total of 10 types including 103 kinds of volatile constituents were identified by 4 different SPME extraction heads,and phenols,esters and hydrocarbons were main chemical types of volatile compounds in Linglingxiang.There were totally 6 volatile constituents detected by 4 different SPME extraction heads,and they were Sugarlactone,Dihydroactinidiolide,(+)-cedrol,phytone,phenanthrene,and 3-Amino-4,5-dimethyl-2 (5h)-furanone.Among all extraction heads,the head of 75 μm CAR/PDMS detected the largest number of volatile constituents reached to 43.Conclusion SPME-GC/MS was used for the first time form determining the volatile constituents in Linglingxiang.The method is simple,rapid and accurate,which can offer reference to further studies on the material base of Linglingxiang.

Objective To predict the quality marker(Q-marker)of Wuwei disinfection decoction based on HPLC fingerprints and network pharmacology.Methods Using the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System(2012 version)software,the fingerprints of 15 batches of Wuwei disinfection decoction were established,and the peaks were found and assigned to each batch.Wuwei disinfection decoction's primary targets and routes were screened using network pharmacology,and a"component-target-pathway"network diagram was established.The five principles of the Q-marker were used to predict the quality marker in Wuwei disinfection decoction.Results The similarity of the fingerprints of 15 batches of Wuwei disinfection decoction was＞0.95,13 peaks were identified,and 11 peaks were recognized as neochlorogenic acid,chlorogenic acid,esculetin,cryptochlorogenic acid,loganin,secoxyloganin,chicoric acid,isochlorogenic acid B,isochlorogenic acid A,isochlorogenic acid C and linarin.Through the pharmacological analysis of the network,it was speculated that chlorogenic acid,esculetin,secoxyloganin,chicory acid,and linarin might be potential Q-marker of Wuwei disinfection decoction,which may regulate multiple genes,such as tumou suppressor p53/oncoprotein Mdm2,tyrosine-protein kinase SRC,as well as multiple cancer pathways such as pancreatic cancer and prostate cancer,to produce anti-tumor and anti-cancer effects.At the same time,Wuwei disinfection decoction was also predicted to be used for the treatment of COVID-19.Conclusion The established HPLC fingerprinting method of Wuwei disinfection decoction was sensitive,rapid,and stable.Based on the network pharmacology results,potential Q-marker with traceability,predictability,and close relevance to the clinical application of Wuwei disinfection decoction was screened,which can provide a reference for further research on Wuwei disinfection decoction in the future.

This paper summarized the clinical experience of AI Rudi in the treatment facial hormone-dependent dermatitis with the method of clearing heat and protecting yin. It is believed that the key pathogenesis is the heat toxin accumulation， yin depletion and collaterals obstruction. The clinical treatment should focus on “heat exuberance” and “yin depletion”. It is advocated that “half treatment is from heat and half from yin” is the general principle， and the treatment is staged. In the acute phase， the treatment is half from cooling blood and dispersing wind to dispel heat pathogen， and half from protecting fluid and moisturizing skin to strengthen yin； and the modified Liangxue Xiaofeng Powder （凉血消风散） could be used. In the chronic phase， half treatment is from clearing residual toxin to eliminate heat pathogen， and half from nourishing yin and unblocking collaterals to strengthen yin， for which Xuanmai Ganju Decoction and Erzhi Pills （玄麦甘桔汤合二至丸） can be used and modified according to the symptoms. At the same time， we should pay attention to the simultaneous internal and external treatment， and emphasize the importance of daily protection in the treatment of the disease.

To summarize Professor AI Rudi's experience in the staged external treatment of eczema by traditional Chinese medicine （TCM）. It is believed that dampness is the key pathological factor of eczema， and the treatment for dampness should be carried out throughout the whole process， with the leading idea of “three-stage treatment， dampness as the root， and treatment according to the symptoms”. The preparation and formulas of the external treatment can be applied according to the pathogenesis and lesion characteristics of each stage. In acute stage with wind-dampness and heat in the skin as the main mechanism， the treatment is to clear heat and astringe， resolve toxins and relieve itching， and the preparation is mostly solution and lotion， and the formula could be Yangzheng Xi Formula （痒症洗方）， Jingfang Kushen Decoction （荆防苦参汤）， Kuding Erhuang Decoction （苦丁二黄汤）， and Xianglian Jinhuang Powder （香连金黄散）. In subacute stage with phlegm-dampness and heat as the main mechanism， the treatment is to remove dampness and turbidity， clean up the residual heat； the preparation is mostly ointment， and the formula include Shehuang Ointment （蛇黄软膏）， Huanglian Ointment （黄连膏）， and Zihuan Diding Ointment （紫花地丁软膏）. In chronic stage with phlegm-dampness stagnation as the main mechanism， the treatment is to remove dampness and eliminate phlegm， remove blood stasis and stop itching， and the formula could be Zhiyang soft Ointment （止痒软膏）， Runji Ointment （润肌膏）， Yufu Ointment （愈肤膏）； jojoba oil and olive oil are often used as external moisturiser for daily care.

This paper summarizes Professor AI Rudi's experience in the diagnosis and treatment of skin pruritus based on the "unity of restoring form， regulating qi， and harmonizing spirit"， employing internal herbal medicine combined with external treatments. It is believed that the core pathogenesis of pruritus is the "imbalance of form， qi， and spirit"， with disturbed spirit as the onset， disordered qi as the key pathogenic factor， and physical changes as the manifestation of the disease. The treatment principle follows "restoring form-regulating qi-harmonizing spirit"， with a combination of internal and external therapies， and differentiation based on deficiency and excess. For excess conditions caused by pathogenic disturbances to the heart spirit， treatment is based on different patterns of wind-heat， damp-heat， and blood-heat， using Sangye （Morus alba）-Sangbaipi （Morus alba cortex）-Longchi （Draconis os） to disperse wind and clear heat， calm the spirit； Difuzi （Kochia scoparia）-Qinghao （Artemisia annua）-Tanxiang （Santalum album） to clear damp-heat and aromatically open the spirit； Mudanpi （Paeonia suffruticosa）-Chuanxiong （Ligusticum chuanxiong）-Shuiniujiao （Bubalus bubalis cornua） to cool the blood， activate circulation， and calm the spirit. For deficiency conditions caused by insufficient nourishment of the heart spirit， treatment is based on patterns of qi deficiency or blood deficiency， using Huangqi （Astragalus membranaceus）-Fuping （Lemna minor）-Wuweizi （Schisandra chinensis） to tonify the qi and stabilize the exterior； Heshouwu （Polygonum multiflorum）-Jili （Tribulus terrestris）-Shouwuteng （Polygonum multiflorum vine） to nourish the blood， moisten dryness， and calm the spirit. External treatments integrate traditional Chinese medicine therapies such as medicinal baths， gua sha， and ear acupuncture， with custom herbal wash formulas for restoring form， jojoba oil gua sha for regulating qi， and ear seed therapy using Wangbuliuxing （Vaccaria segetalis） for harmonizing the spirit， achieving a holistic treatment effect for form， qi， and spirit.
