ObjectiveBased on the network pharmacology system and quantitative spectroscopy of traditional Chinese medicine(TCM) compounds, a topological network analysis method with equilibrium constant as the core was established to further explore the interaction between allergenic components and their network targets in Shuanghuanglian injection(SHLI), in order to provide new ideas and experimental basis for identifying and screening potential allergens of SHLI. MethodAfter one week of adaptive feeding, 72 SPF-grade SD male rats were randomly divided into blank group, SHLI standard group, Lonicerae Japonicae Flos(LJF) group, Scutellariae Radix(SR) group, Forsythiae Fructus(FF) group, and 7 groups of SHLI matching groups(groups 1-7), with 6 rats in each group. Rats in each group were administered the drug intravenously and blood samples were taken after steady state, high performance liquid chromatography(HPLC) characterization profiles of the testing drugs and plasma components in each group were established, and the peak area changes of the drugs and plasma components in each group were calculated after the component groups were classified. Enzyme-linked immunosorbent assay(ELISA) was used to determine the changes of immunoglobulin E(IgE), histamine(HIS), tryptase(TPS), total complement(CH50) and terminal complement complex(C5b-9) in animal blood samples. MATLAB R2020b v9.9.0 software was used to calculate the network balance constants of the component groups with the targets, and the eigenvalues of the matrices composed of network equilibrium constants were calculated and ranked according to their values. ResultELISA results showed that, compared with the blank group, groups 1-3 could significantly increase the IgE level, groups 1-2, groups 4-6 and SHLI standard group could significantly increase the HIS level, group 4 could significantly increase the CH50 level, groups 1, 3-4, LJF group and FF group could significantly increase the TPS level, SR group could significantly increase the C5b-9 level, and the differences were all statistically significant(P<0.05). According to the retention time of chromatographic peaks, it was classified into 6 component groups from C1 to C6 by HPLC. The order of the network balance constants of each component group was C6>C4>C1>C5>C3>C2, indicating that C6 had the greatest effect on the allergic reaction, and was most likely to be the allergen. The sequence of eigenvalues was C2>C5b-9>C3>C1>CH50>C6>C5>IgE>TPS>C4>HIS, indicating that component group C2 had the greatest contribution to the whole network. ConclusionBased on the correlation analysis of SHLI component group and allergy-like target network, this study clarified that component group C6 may be a potential allergen in SHLI, and the component group C2 may be a key node in the mechanism of drug action, which can provide new strategies and methods for the screening of allergens in TCM injections.

MethodRelevant literature at home and abroad and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) were consulted to establish the chemical composition database of AFI and AF, and set up their fingerprints by ultra-high performance liquid chromatography(UPLC), and the total statistical moments and similarity parameters of the fingerprint were calculated. According to MCI, all components of AFI and AF were divided into different component groups, the average values of 0-8th order(0χ-8χ) MCI of the common component groups of AFI and AF were calculated. ResultThe values of total zero-order moment(AUCT) of AFI and AF were (10.57±2.45)×106, (5.09±0.89)×106 μV·s, the values of total first-order moment(MCRTT) were (11.57±1.58), (12.10±1.29) min, the values of total second-order moments(VCRTT) were(24.49±2.30), (26.49±2.54) min2, respectively. It showed that qualitative and quantitative parameters of AFI and AF were significantly different. The components with high similarity such as neohesperidin, hesperidin and narirutin were screened as the common potential pharmacodynamic components of AFI and AF. The non-common components of AFI, such as alysifolinone and imperatorin, and the non-common components of AF, such as neoeriocitrin and isosakuranin, with high similarity were screened out as potential heterogeneous components of AFI and AF. The composition groups of AFI and AF were classified into six categories, and the similarities between the composition groups of AFI and AF and the total constituents were 0.872-0.979 and 0.918-0.997, the average values of 0χ-8χ MCI of alkaloids in AFI and AF were 3.65 and 3.14, the average values of 0χ-8χ MCI of flavonoids were 8.47 and 8.47, the average values of 0χ-8χ MCI of volatile oils were 2.71 and 3.48, respectively. It showed that there were some differences in MCI of chemical constituents(groups) between AFI and AF. ConclusionThe chemical constituents(groups) of AFI and AF not only differ in content and species, but also in structural characteristics and structure-activity relationship, which can provide a basis for further explaining the scientific connotation of homologous and heterogeneous effect of AFI and AF.

ObjectiveTo compare the similarities and differences of material basis for improving insulin resistance (IR) in different parts of Morus alba based on liquid-mass combination combined with network pharmacology and molecular docking technology. MethodUltra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used to analyze the composition differences in different parts of M. alba. Sybyl-X2.1 was used to connect components with IR core targets, and the selection criterion was Total Score≥5. The "component-target-disease" network map was drawn. The total statistical moment standard similarity (TQSMSS) between the single target-component docking score data set and the total target-component docking score data set was calculated. The targets with higher TQSMSS were screened out, and the protein-protein interaction (PPI) network was constructed. The Gene Ontology (GO) functional analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed using R language. ResultForty-one active components were obtained by UPLC-Q-TOF-MS. According to the total statistical moment (similarity) method, there were 20, 23, 30, and 27 targets with TQSMSS≥0.75 in Mori Ramulus, Mori Cortex, Mori Fructus, and Mori Folium, respectively. In the four M. alba medicinal sources, the functional order of the targets by GO enrichment analysis was Mori Fructus>Mori Folium>Mori Cortex>Mori Ramulus, which were involved in biological processes such as blood glucose homeostasis, glucose metabolism, and glucose transmembrane transport. The order of the four M. alba medicinal sources by KEGG pathway enrichment analysis was Mori Fructus>Mori Ramulus>Mori Folium>Mori Cortex, which were involved in the adenosine monophosphate-activated protein kinase (AMPK) energy metabolism signaling pathway, the insulin regulation-related signaling pathway, the anti-inflammatory and anti-oxidative stress signaling pathway, and so on. ConclusionThis research demonstrates that there are differences in the material basis for improving IR by different parts of M. alba, which provides references for the development of different parts of M. alba.

Objective:To establish the clinical laboratory genetic diagnosis procedures for Marfan syndrome (MFS) and carry out clinical laboratory genetic diagnosis for MFS families.Methods:The second generation high-throughput sequencing was used to sequence and analyze the FBN1 gene of two MFS families who visited to Fuwai Central China Cardiovascular Hospital (Heart Center of Henan People′s Hospital) from January to December 2020, and then Sanger sequencing was used to verify the second generation high-throughput sequencing results. At the same time, the sanger sequencing of mutation sites was performed on normal family members and 100 healthy people to identify the pathogenic mutations of FBN1 gene in the MFS families. The pregnant women of two families were guided for prenatal diagnosis in the second trimester of pregnancy.Results:The clinical laboratory diagnosis of MFS showed that two MFS patients had the pathogenic mutation of c.2560T>C heterozygous mutation and c.6772T>C heterozygous mutation in FBN1 gene, respectively. The mutation was not observed in 100 healthy people and normal members in two families. The prenatal diagnosis showed that there was a heterozygous mutation of FBN1 gene c.2560T>C in the first fetus of the MFS family, which was MFS. There was no mutation in the FBN1 gene in the second fetus of the MFS family, so it was recommended to continue the pregnancy. The results of postpartum follow-up were consistent with the results of clinical laboratory diagnosis.Conclusion:The clinical laboratory genetic diagnosis procedures for MFS have been established successfully, which provides an important reference for clarifying the clinical diagnosis of MFS.

Ganjiang (Zingiberis Rhizoma, ZR) and Jiangtan (Carbonized Zingiberis Rhizoma, CZR) have
long been used in traditional Chinese medicine (TCM) with a rich history in the treatment of
various ailments. While ZR and CZR obviously stem from the same botanical source, their attributes, chemical compositions, pharmacological behaviors, and clinical applications are different owing to variations in the extent of drying and processing they undergo. In this paper,
data pertaining to ZR and CZR were retrieved from databases including China National
Knowledge Infrastructure (CNKI), PubMed, Web of Science, and Google Scholar. These
sources were scrutinized to elucidate the distinctions between ZR and CZR arising from carbonization processing in terms of their ethnopharmacology, quality control, chemical compositions, biological activities, pharmacological mechanisms, and clinical uses. In this study,
a total of 56 chemical constituents were identified and isolated from ZR and CZR, which primarily encompassed volatile oils, gingerols, and diphenylheptane compounds. CZR's pharmacological effects include hemostatic, anti-oxidant, analgesic, antibacterial, anti-cancer,
and other biological activities. ZR has pungent and warm properties. It is a Yang-supplementing herbal medicine for ailments exacerbated by cold or damp climatic influences. CZR is a
product of ZR after undergoing high temperature, with diminished intensity of its pungent
and warm attributes. This change leads to a more gradual treatment efficacy, renowned
hemostatic effects and its ability to gently invigorate the spleen and effectively alleviate diarrhea. Currently, research on the pharmacological mechanism of CZR is mainly focused on the
effects of CZR on coagulation and fibrinolysis. Although the healing effect of CZR has long
been known, and some correlation has been found between the changing composition and
the changing color of the decoctions, people still lack relatively clear processing mechanisms
to reflect the characteristics and specific quality standards of the ingredients of CZR's hemostatic effect. This review provides a systematic summary on quality control, chemical composition, ethnopharmacology, and pharmacology of CZR, offering novel perspectives for advancing the exploration of additional carbonized herbal medicine and fostering their application in clinical settings
