ObjectiveTo investigate the contamination status and drug resistance of diarrheagenic Escherichia coli (DEC) in commercially available frozen poultry and livestock meat and their products in Zhangzhou City, and to provide a reference basis for the prevention and control of foodborne diseases caused by DEC. MethodsIn 2024, a total of 240 samples of frozen poultry and livestock meat and their products were collected from supermarkets, farmers’ markets, and online stores. Isolation, identification, and drug resistance analyses of DEC were conducted. ResultsAmong the 240 samples, 42 samples tested positive for DEC, with a detection rate of 17.50%. Specifically, the DEC detection rate in frozen poultry meat and its products （21.15%） was significantly higher than that in frozen livestock meat and its products （10.71%） (χ²=4.122, P=0.042); the detection rate in the first and fourth quarters （26.67%） was higher than that in the second and third quarters （8.33%） (χ²=13.968, P=0.003). A total of 44 DEC strains were isolated, among which enteroaggregative Escherichia coli (EAEC) was the dominant pathotype, accounting for 90.91%, and mainly carried the astA gene, followed by the pic gene. At a distance level of 10 000 in matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) cluster analysis, the 44 DEC strains were divided into 2 major clusters, with 29 strains in Cluster Ⅰ and 15 strains in Cluster Ⅱ； at a distance level of 200, the strains could be classified into 12 types, with type c being the dominant one (27.27%). Among the 44 DEC strains, 37 DEC strains showed different degrees of resistance to 11 categories of antibiotics, 36 strains were resistant to 3 or more classes of antibiotics, with multidrug-resistant strains accounting for 81.82%, and 21 strains were resistant to more than 7 types of antibiotics. ConclusionThe detection rate of DEC in commercially available frozen poultry and livestock meat and their products in Zhangzhou City is relatively high, and the prevalence of multidrug resistance is severe. These findings should warrant the attention of relevant authorities, to strengthen food safety supervision and the management of antibiotic use, and enhance public health education to reduce the risk of foodborne diseases caused by DEC contamination.

In this study, RAW264.7 cells were employed to investigate the effects of honey-processed Astragalus on their energy metabolism and polarization, and explore the scientific connotation of the enhanced efficacy of honey-processed Astragalus on invigorating spleen-stomach and replenishing Qi. The medicated sera were prepared by intragastric administration of rats with water extracts of crude and honey-processed Astragalus, and the composition changes of medicated sera of crude and honey-processed Astragalus were analyzed by using LC-MS technology. The cell survival rates were detected and the concentrations of medicated sera were screened through CCK-8 assay. The differences of cell phagocytic rates, ATP energy metabolism, and NO secretion between crude and honey-processed Astragalus were evaluated by using neutral red phagocytosis assay, ATP detection kit, and NO detection kit. The effects of crude and honey-processed Astragalus on TNF-α secretion of RAW264.7 cells were detected by employing ELISA kit. The effects of crude and honey-processed Astragalus on polarization of RAW264.7 cells were evaluated by utilizing flow cytometry. The differential metabolites related to glycolysis in cell lysates and culture media were screened by using LC-MS technology. The experiment was approved by the experimental animal ethics committee from Shanxi University of Chinese Medicine (No. AWE202407352). The results showed that the contents of betaine, amino acids, and ononin in the prepared medicated sera of rats treated by intragastric administration with water extracts of honey-processed Astragalus increased compared to those in crude one. The results of CCK-8 experiment showed that there were no cytotoxic effects on RAW264.7 cells in the medicated sera of crude and honey-processd Astragalus at different concentration. The phagocytic index and ATP yield both increased to varying degrees after administration of the medicated sera to cells. The secretion of NO in normal and inflammatory cells increased and decreased respectively, and the effect of honey-processed Astragalus was better than that of crude one. The results of ELISA kit showed that the medicated sera of both crude and honey-processed Astragalus could promote the secretion of TNF-α in a concentration-dependent manner, and the promoting effect of honey-processed Astragalus was stronger than that of crude one. The results of flow cytometry showed that the medicated sera of both crude and honey-processed Astragalus could promote M1-type polarization and inhibit M2-type polarization of RAW264.7 cells, and the effect of honey-processed Astragalus was better than that of crude one. Compared to crude Astragalus, the metabolites related to glycolysis in the cell lysates and culture media of the medicated sera of honey-processed Astragalus were generally on the rise, indicating that the effect on promoting glycolysis of honey-processed Astragalus was better than that of crude one. In summary, honey-processed Astragalus can promote the polarization and energy metabolism of RAW264.7 cells, and participate in positive immune regulation, which is correlated with its enhanced effect of invigorating spleen-stomach and replenishing Qi.

Medicinal plant germplasm resources are the foundation of the modern development of traditional Chinese medicine. In-depth study of medicinal plant germplasm resources is a prerequisite for cultivating fine varieties and ensuring the output and standard quality of traditional Chinese medicine（TCM）. Traditional identification methods start with appearance and are greatly affected by natural environment and human factors，with a low efficiency and accuracy of identification are generally low molecularin general. Due to such advantages as easy operation，high sensitivity，accurate results， molecular biology technology has been widely used in the related research of relevant studies for medicinal plant germplasm resources due to its advantages of easy operation，high sensitivity，accurate results，etc. It mainly involving the distinction between wild and cultivated products，researchstudy on substitutes of TCM，identification of Chinese patent medicine，good variety marker breeding，genetic diversity researchstudy，genetic map establishment and omics research，etcstudy. Among them，omics researchstudy is divided into genomics，transcriptomics，metabolomics，and proteomics due toby different analysis purposes. Genomics is divided into three sub-fields namely structural genomics，functional genomics， and comparative genomics. Eukaryotes Because eukaryotes have nuclei and organelles，so omics researchstudy also includes chloroplast genomics，mitochondrial genomics，nuclear genomics，and plastid genomics. Among them，the chloroplast genome has a simple structure，small molecular weight，and good conservation，while the mitochondrial genome has a strong variability and complex structure，the nuclear genome data isfeatures complex， data and the nucleus contains no ribosomes in nucleus，resulting in spatiotemporal differences in the translation process，even if repeated repeatedly test， the result of and the test is alsoresults remained uncertain， even after repeated tests. The molecular biology technology and omics researchstudy involved in theby current medicinal plant researchstudy still hashave shortcomings，and there iswith a large room for development，which needs and need further improvement and supplementation. This articlepaper successively introduces the characteristics and applications of cytology，molecular markers，and omics researchstudy techniques in the identification of medicinal germplasm resources，providingin order to provide a reference for subsequent identification，development and utilization of medicinal plant germplasm resources.

To effectively identify the Astragalus and its adulterants based on ITS2 sequence and secondary structure, in this study, 32 portions of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Beg.) Hsiao and Astragalus membranaceus (Fisch.) Bge. collected were conducted ITS2 sequence amplification and bidirectional sequencing, whose results were then spliced by CExpress software remove the 5.8S and 28S sequences at both ends to obtain a complete ITS2 sequence. In addition, 3 ITS2 sequences for each of the adulterants of Astragalus, respectively, Oxytropis coerulea, Caragana sinica, Hedysarum polybotrys, Althaea rosea were downloaded from GenBank. The intra-specific and inter-specific genetic distances were calculated by the software MEGA7 to analyze the difference of each sequence; the Neighbor-joining (NJ) method was used to construct the phylogenetic tree based on ITS2 sequence (primary structure) as well as joint ITS2 sequence and its secondary structure. The results showed that the average ITS2 sequence length of both A. mongolicus and A. membranaceus was 216 bp, and their average GC content was 50.00% and 50.46%, respectively. The similarity of ITS2 sequence length and GC content between the two kind of Astragalus and Oxytropis coerulea was the highest, while the ITS2 sequence length and GC content of Althaea rosea showed great differences with those of Astragalus. The inter-specific distance between Astragalus and Oxytropis coerulea was the smallest, while that between the medicinal Astragalus and Hedysarum polybotrys, Caragana sinica as well as Althaea rosea was great. The phylogenetic trees constructed based on the ITS2 sequence (primary structure) and joint ITS2 sequence and its secondary structure showed that the topological relations of the two phylogenetic trees were basically the same, and both could effectively identify the Astragalus and its adulterants. What’s more, the addition of secondary structure information made end branch of the phylogenetic tree become more in its construction, and the distinguish ability and approval rating were also improved, which further reflected the genetic relationship of Astragalus and its adulterants. This provides some scientific basis for classification and accurate identification of Astragalus and its adulterants.

NSCL/P is a common congenital defect and gene-environmental factors involve in this disorder. Periconceptional intake of folate may reduce the risk of NSCL/P. The present study investigated three SNPs (rs1801198, rs955516, and rs3733890) in three folate pathway genes, including TCN2, MTR, and BHMT among 481 patients and 558 healthy subjects. Rs955516 showed allelic association with NSCL/P. More patients carry rs955516 AA and rs3733890 AA genotypes. The gene-gene interaction test showed trans-phase combination effects for MTR and BHMT genes. Our study suggests that the interaction of MTR and BHMT genes play a vital role in the pathogenesis of NSCL/P in Chinese population.
