OBJECTIVE:To establish UPLC fin gerprint of 32 compatible herb pairs with Polygonum multiflorum as the core , and to conduct multivariate statistical analysis. METHODS :UPLC method was adopted. Using P. multiflorum and single decoction pieces of compatible herb as reference ,UPLC fingerprints of 32 compatible herb pairs of P. multiflorum were drawn. Common peaks were confirmed by relative retention time and UV absorption spectrum. Non-supervised PCA and supervised OPLS-DA were conducted by using SPSS 19.0 software and SIMCA 13.0 software. RESULTS :There were totally 12 common peaks in UPLC fingerprints of 32 compatible herb pairs of P. multiflorum . The results of non-supervised PCA showed that the accumulative variance contribution rate of primary 6 principal components was 84.633%. The results of cluster analysis of PCA comprehensive score showed that single decoction piece of P. multiflorum ,compatible herb pairs of P. multiflorum with Lycium barbarum ,Rehmannia glutinosa,Paeonia lactiflora ,Codonopsis pilosula ,Eclipta prostrate ,Angelica sinensis ,Glycyrrhiza uralensis ,Astragalus membranaceus and Ophiopogon japonicus were clustered into one category ;others were clustered into one category. Results of supervised OPLS-DA analysis showed that eigen values of 4 principal components were 2.32,2.61,1.58 and 0.90,respectively. There were differences in the contents of 12 common components in the compatibility of P. multiflorum with tonic medicine and non-tonic medicine. The changes of the content of the components after compatibility with tonic medicine were similar. Common peak 7,4,6,3 were main reasons for the differences (variable importance projection value were all higher than 1). CONCLUSIONS:Established fingerprint is simple in operation ,and can be combined with multivariate statistical analysis to evaluate the content changes of common components of 32 compatible herb pairs with P. multiflorum as the core.

Objective:To investigate the characteristics of allergen component in dust mite(DM) -induced allergic rhinitis(AR) patients, and provide reference for the diagnosis and treatment of AR. Methods:DM-induced AR patients with or without allergic asthma(AA) who visited the Allergy Department of Tongji Hospital, Huazhong University of Science and Technology between 2021 and 2022 were enrolled. Patients'age, gender, and visual analog scale(VAS) for symptoms were recorded. sIgE and sIgG4 levels of allergen components such as Der f1, Der f2, Der p1, Der p2, Der p7, Der p10, Der p21, and Der p23 were detected using a protein chip method. The sensitization characteristics of the allergen components in the patients were observed, and the correlation between sIgE, sIgG of each component and VAS as well as the component differences between AR and AR with AA(AR&AA) were evaluated. Results:A total of 87 DM-induced AR patients were enrolled, with 42.5% of them were AR&AA, their VAS scores were significantly higher than those of AR patients(6.38±1.95 vs 5.25±1.85, P=0.009 8). The order of sensitization rates for DM components was as follows: Der p2(82.8%), Der f2(81.6%), Der p1(74.7%), Der f1(70.1%), and Der p23(35.6%). The order of positive rates for sIgG4 was: Der p2(21.8%), Der f2(13.8%), Der p21(8.0%), and Der p7(6.9%). There were no correlation between the sIgE, sIgG4 levels or positive numbers of components and VAS scores, but there were positive correlations between sIgE, sIgG4 concentrations of components. Compared with AR patients, AR&AA patients had higher levels of sIgE for Der p(60.5[7.2-91.1]vs 14.0[4.8-45.1], P=0.02), Der f(49.8[15.7-81.6]vs 21.3[7.0-50.2], P=0.04), Der p1(27.2[0.7-51.5]vs 2.6[0.2-24.9], P=0.02), Der p2(20.0[1.4-60.6]vs 5.5[0.6-19.1], P=0.004), and Der f2(58.9[16.0-89.2]vs 23.4[0.9-56.8], P=0.009), and a higher proportion of AR with AA patients had sIgE levels of Der p1(70.3% vs 48.0%, P=0.038) and Der p23(27.0% vs 14.0%, P=0.039) that were ≥3 grades. Conclusion:Der p1/f1, Der p2/f3, and Der p23 are the major components of DM sensitized AR patients. Multiple component sensitization and sIgE, sIgG4 levels of each component are not correlated with the severity of AR. The sIgE levels of the Der p1/f1, Der p2/f3, and Der p23 components in AR&AA patients are higher than AR.
