This experiment aims to study the taste-masking effects of different kinds of corrigent used individually and in combination on ibuprofen oral solution, in order to optimize the taste-masking formulation. Firstly, a wide range of corrigent and the mass fractions were extensively screened using electronic tongue technology. Subsequently, a combination of sensory evaluation, analytic hierarchy process (AHP)-fuzzy mathematics evaluation, and Box-Behnken experimental design were employed to comprehensively assess the taste-masking effects of different combinations of corrigent on ibuprofen oral solution, optimize the taste-masking formulation, and validate the results. The study received ethical approval from the Review Committee of the Beijing University of Chinese Medicine (ethical code: 2024BZYLL0102). The results showed that corrigent fractions and types were screened separately through single-factor experiments. Subsequently, a Box-Behnken response surface design combined with AHP and fuzzy mathematics evaluation was used to fit a functional model: Z = 688.310 11 - 3 023.722 22X₁ - 11.477 00X₂ + 62.721 67X₃ + 14.600 00X₁X₂ - 179.666 67X₁X₃ - 3.152 00X₂X₃ + 4 031.111 11X₁² + 0.525 28X₂² + 9.772 00X₃². This model is stable and reliable, determining the optimal taste-masking formulation to be 3.9 g·L^-1 of stevioside, 100 g L^-1 of xylitol, and 30 g L^-1 of methyl-β-cyclodextrin. The comprehensive score of the verification test is 88.14, with a relative RSD of 0.39%, indicating the feasibility of this model. This study achieved the improvement of the taste of ibuprofen oral solution through a combination of objective and subjective methods. Three types of corrigent were identified for enhancing drug taste, leading to the selection of the optimal taste-masking formulation for ibuprofen oral solution. This significantly enhanced the taste of the original formulation, improved patient compliance, and offered a new approach to mitigating the undesirable taste of formulations.

Inductively coupled plasma mass spectrometry (ICP-MS) was applied to determine the concentrations of lead (Pb), cadmium (Cd) and arsenic (As) in Lindera aggregata (Sims) Kosterm. The physiologically based extraction test (PBET) digestion in vitro/Caco-2 cell model was established to investigate the bioaccessible contents of Pb, Cd and As in decoction of Lindera aggregata (Sims) Kosterm. The target-organ toxicity dose modification of HI method (TTD) was used to evaluate the cumulative risk caused by the combined exposure of the total levels of Pb, Cd and As in Lindera aggregata (Sims) Kosterm. and the bioaccessible contents in the decoction. The results showed that the total contents of Pb, Cd and As in 4 batches of samples were in the range of 2.901-3.872, 1.299-1.800 and 0.062-0.216 mg·kg^-1, respectively. After transportation by Cacco-2 cells, the bioaccessible contents of Pb, Cd, and As in the decoction were in the range of 0.045-0.080, 0.070-0.112 and 0.004-0.018 mg·kg^-1. The results of risk assessment showed that calculated by the total amounts of heavy metals in the Lindera aggregata (Sims) Kosterm., for the end points of nervous system, the cumulative risks of co-exposure of heavy metals in 3 batches of samples were of concern. After decoction and transportation by Caco-2 cells, for the end points of cardiovascular system, blood, nervous system, kidney and testis, the TTD modification of HI values of all batches of samples were less than 1, and the health risks were acceptable. The study provided methodology basis for a more objective assessment of the health risks of heavy metals and harmful elements in traditional Chinese medicine and for a more scientific limit standard of heavy metals and harmful elements.

Objective To analyze the distribution and type characteristics of human papillomavirus (HPV) infection in women in Shiyan, Hubei region, so as to provide a basis for the prevention and treatment of HPV infection. Methods From January 2019 to December 2020, a sample of 3,180 women in XX region who had sexual intercourse experience were randomly selected, and their HPV genotypes were tested using flow-through hybridization, then the distribution characteristics and types of HPV infection in women of different ages were observed. Results Among of 3 180 patients, HPV infection was predominant in women aged 31-50 years , with 25.85% (822/3 180) aged 31-40 years and 22.08% (702/3,180) aged 41-50 years. HPV infection was the least prevalent in the ≤25 and >60 years age groups, with 428 cases and 289 cases respectively. HPV infection occurred in 1 310 out of 3 180 women , with a positive infection rate of 41.19% (1 310/3 180). HPV infection was most prevalent in the ≤25 years and ≥60 years age groups, accounting for 56.78% and 67.13% respectively. Single infection was the main infection type in all age groups, accounting for 76.03%. Twenty-one HPV genetic subtypes were detected in the subjects, out of a total of 1 918 strains of the virus. The main high-risk subtypes for single infection were HPV16, HPV52 and HPV58, accounting for 13.92%, 13.87% and 12.57% respectively, followed by HPV53 and HPV33, accounting for 7.61% and 5.58% respectively. The predominant low-risk subtypes for single infection were HPV11, HPV8 and HPV6, with accounting for 7.51%, 5.47% and 5.01% respectively. Conclusion HPV infection in women in Shiyan, Hubei region is predominantly in the ≤25 and ≥60 years age groups, and early clinical screening and preventive measures such as vaccination for high-risk HPV typing are of vital importance.

Tanshinones are one of the main effective components of Salvia miltiorrhiza, which play important roles in the treatment of cardiovascular diseases. Microbial heterogony production of tanshinones can provide a large number of raw materials for the production of traditional Chinese medicine(TCM) preparations containing S. miltiorrhiza, reduce the extraction cost, and relieve the pressure of clinical medication. The biosynthetic pathway of tanshinones contains multiple P450 enzymes, and the catalytic element with high efficiency is the basis of microbial production of tanshinones. In this study, the protein modification of CYP76AK1, a key P450-C20 hydroxylase in tanshinone pathway, was researched. The protein modeling methods SWISS-MODEL, Robetta, and AlphaFold2 were used, and the protein model was analyzed to obtain the reliable protein structure. The semi-rational design of mutant protein was carried out by molecular docking and homologous alignment. The key amino acid sites affecting the oxidation activity of CYP76AK1 were identified by molecular docking. The function of the obtained mutations was studied with yeast expression system, and the CYP76AK1 mutations with continuous oxidation function to 11-hydroxysugiol were obtained. Four key amino acid sites that affected the oxidation acti-vity were analyzed, and the reliability of three protein modeling methods was analyzed according to the mutation results. The effective protein modification sites of CYP76AK1 were reported for the first time in this study, which provides a catalytic element for different oxidation activities at C20 site for the study of the synthetic biology of tanshinones and lays a foundation for the analysis of the conti-nuous oxidation mechanism of P450-C20 modification.

Although herbal medicines(HMs)are widely used in the prevention and treatment of obesity and obesity-associated disorders,the key constituents exhibiting anti-obesity activity and their molecular mechanisms are poorly understood.Recently,we assessed the inhibitory potentials of several HMs against human pancreatic lipase(hPL,a key therapeutic target for human obesity),among which the root-extract of Rhodiola crenulata(ERC)showed the most potent anti-hPL activity.In this study,we adopted an integrated strategy,involving bioactivity-guided fractionation techniques,chemical profiling,and biochemical assays,to identify the key anti-hPL constituents in ERC.Nine ERC fractions(retention time=12.5-35 min),obtained using reverse-phase liquid chromatography,showed strong anti-hPL activity,while the major constituents in these bioactive fractions were subsequently identified using liquid chromatography-quadrupole time-of-flight mass spectrometry(LC-Q-TOF-MS/MS).Among the identified ERC constituents,1,2,3,4,6-penta-O-galloyl-β-D-glucopyranose(PGG)and catechin gallate(CG)showed the most potent anti-hPL activity,with pIC50 values of 7.59±0.03 and 7.68±0.23,respectively.Further investigations revealed that PGG and CG potently inhibited hPL in a non-competitive manner,with inhibition constant(Ki)values of 0.012 and 0.082 μM,respectively.Collectively,our integrative analyses enabled us to efficiently identify and characterize the key anti-obesity constituents in ERC,as well as to elucidate their anti-hPL mechanisms.These findings provide convincing evidence in support of the anti-obesity and lipid-lowering properties of ERC.

ObjectiveTo explore the material basis and mechanism of Nardostachyos Radix et Rhizoma （NRER）-Agrimoniae Herba （AH）， the herbal pair effective in regulating the liver， invigorating Qi， and calming palpitations， in the treatment of premature ventricular contractions （PVCs） by network pharmacology and molecular docking. MethodThe chemical components and targets of NRER and AH were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） combined with relevant literature. GeneCards，Online Mendelian Inheritance in Man（OMIM），and DrugBank were used to predict the potential targets against PVCs. STRING platform was used for protein-protein interaction （PPI） analysis. Metascape platform was used for Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analysis. Cytoscape 3.8.0 was used to construct the NRER-AH component-potential target-signaling pathway network. The main target proteins underwent molecular docking to the active components of NRER-AH by AutoDock 4.2.6. ResultThe targets of nine active components in NRER-AH （such as quercetin，kaempferol，and acacetin） against PVCs mainly involved tumor necrosis factor （TNF），mitogen-activated protein kinase 1（MAPK1），and protein kinase B1（Akt1）. The potential targets were mainly enriched in 26 signaling pathways，such as pathways in cancer and the advanced glycosylation end product （AGE）-receptor of advanced glycosylation end product（RAGE） signaling pathway. The results of molecular docking showed that the majority of the active components （92.59%） of NRER-AH had good binding activities with the main target proteins TNF，MAPK1，and Akt1. ConclusionThe active components of NRER-AH can regulate cardiac ion channels，resist inflammation， and combat oxidative stress to treat PVCs through multi-target and multi-pathway interventions. They can also improve symptoms related to depression and anxiety by inhibiting monoamine oxidase activity and protecting nerves from damage. This study is expected to provide research ideas and the theoretical basis for further exploring the material basis and mechanism of NRER-AH in the treatment of PVCs.

High-throughput transcriptome sequencing was used to study the mechanism of Shenling Baizhu Powder(SLBZP) in the alleviation of the dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) in mice. The mouse model of DDS-induced UC was treated with SLBZP by gavage. The changes in general state, disease activity index(DAI), and colon length were observed. The hematoxylin-eosin(HE) staining was used to observe the pathological changes in the colon tissues of mice. Enzyme-linked immunosorbent assay(ELISA) was used to determine the expression levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, IL-6, IL-4, and IL-10 in the serum and tissues of mice. The differentially expressed genes in the control group, the model group, and the SLBZP group were analyzed by high-throughput transcriptome sequencing, and the Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were conducted on the differentially expressed genes. The results showed that after intragastric administration of SLBZP, the symptoms of diarrhea and bloody stool were improved, and the disease active index(DAI) score was reduced. SLBZP effectively reduced the inflammatory cell infiltration and goblet cell loss in the colonic mucosal tissue, reduced the levels of TNF-α, IL-1β, IL-6 in the serum and colon tissue, and increased the levels of IL-4 and IL-10 in the serum and colon tissue. There were 25 differential genes in SLBZP vs the model group, which were significantly enriched in immune response, immune system process, immunoglobulin production, and other biological processes. KEGG pathway analysis showed that the differential genes were enriched in signaling pathways such as neomycin, kanamycin, and gentamicin biosynthesis, cytokine-cytokine receptor interaction, primary immunodeficiency, and IgA synthesis of the intestinal immune network. This study shows that SLBZP may alleviate UC through immune regulation.

OBJECTIVES: To investigate the current status of sleep initiation patterns, influencing factors for sleep initiation patterns, and the influence of sleep initiation patterns on sleep quality in infants and young children. METHODS: A total of 521 infants and young children, aged 0-35 months, who underwent physical examination at the outpatient service of the Department of Growth and Development in Shenzhen Bao'an Women's and Children's Hospital Affiliated to Jinan University were enrolled as subjects. A self-designed questionnaire and Brief Infant Sleep Questionnaire were used to collect the information on family background, parenting behaviors, and sleep quality in the past one week. A multivariate logistic regression analysis was used to evaluate the influencing factors for sleep initiation patterns. A multiple linear regression analysis was used to evaluate the influence of sleep initiation patterns on the number of nighttime awakenings. RESULTS: Among the 521 infants and young children, 258 (49.5%) were breastfed/bottle fed to initiate sleep, 62 (11.9%) were rocked/held to initiate sleep, 39 (7.5%) slept independently, and 162 (31.1%) initiated sleep accompanied by parents. The multivariate logistic regression analysis showed that the children with breastfeeding and a younger age were more likely to be breastfed/bottle fed to initiate sleep (P<0.05) and that the children with a younger age were also more likely to be rocked/held to initiate sleep (P<0.05). The multiple linear regression analysis showed that sleep initiation with breastfeeding/bottle feeding significantly increased the number of nighttime awakenings (P<0.05). CONCLUSIONS Most infants and young children initiate sleep by being breastfed/bottle fed, rocked/held, or accompanied. The sleep initiation pattern is associated with the age of children and whether they are still breastfeeding. Sleep initiation with breastfeeding/bottle feeding can increase the number of nighttime awakenings. io.
