ObjectiveTo investigate the changes in chemical components of Gardeniae Fructus(GF) before and after being charred, providing data support for research on the material basis of GF Carbonisata(GFC). MethodsUltra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Orbitrap MS/MS) was used to conduct a comprehensive analysis of the chemical components in GF and GFC under positive and negative ion modes with Compound Discoverer 3.3 software and online database. Then, principal component analysis and partial least squares-discriminant analysis in SIMCA14.1 software were used to analyze the MS data of each sample. Based on the principle of variable importance in the projection(VIP) value>1, differential secondary and primary metabolites before and after carbonization were screened. In addition, MetaboAnalyst website was used for pathway enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG), so as to provide a reference for clarifying the processing mechanism. ResultsA total of 185 components were identified, including 96 secondary metabolites and 89 primary metabolites. These components were classified into nine categories, primarily including iridoid glycosides, flavonoids, and terpenoids, their fragmentation pathways were also analyzed. Simultaneously, multivariate statistical analysis was performed on the secondary and primary metabolites, identifying 70 and 59 differential metabolites, respectively. The secondary metabolites were enriched in two metabolic pathways, including C5-branched dibasic acid metabolism and flavonoid and flavonol biosynthesis, while the primary differential metabolites were enriched in seven pathways such as linoleic acid metabolism and tyrosine metabolism. ConclusionThe chemical components of GF change significantly after carbonization, with a significant decrease in the contents of iridoid glycosides and terpenoids such as hydroxyisogeniposide, crocin Ⅱ, crocetin, and jasminoside B. while the contents of 4-hydroxycoumarin, geniposidic acid, gentiopicroside, and gardenoside methyl ester increase significantly. This change is presumed to be associated with the enhanced cooling and hemostatic effects of the processed products. The identified key components provide a basis for elucidating the material basis underlying the efficacy changes before and after carbonization.

Objective To investigate whether miR-15b-5p can alleviate airway inflammation in asthma by negatively regulating ubiquitin specific peptidase 9X (USP9X) to down-regulate the expression of phosphatidylinositol 4, 5-diphosphate 3-kinase catalytic subunit α/AKT serine/threonine kinase 1 (PIK3CA/AKT1) pathway. Methods USP9X was predicted to be a direct target of miR-15b-5p by using an online database (miRWalk), and the luciferase reporter gene assay was performed to verify it. Co-immunoprecipitation (CO-IP) was used to verify the direct binding between USP9X and PIK3CA and the role of USP9X and its small molecule inhibitor WP1130 in the deubiquitination of PIK3CA. C57 mice were randomly divided into Control group, OVA group, OVA combined with NC group and miR-15b-5p agomir group, with 10 mice in each group. BEAS-2B cells were induced with interleukin 13 (IL-13) and treated with miR-15b-5p mimic. HE, Masson, PAS, immunohistochemistry, immunofluorescence staining, flow cytometry, Western blot and quantitative real-time PCR(qRT-PCR) were performed. Results It was found that the administration of miR-15b-5p agomir and mimic could reduce peribronchial inflammatory cells and improve airway inflammation, and miR-15b-5p could target negative regulation of USP9X. USP9X could directly bind to PIK3CA and regulate PIK3CA level in a proteasome-dependent manner, and USP9X could deubiquitinate K29-linked PIK3CA protein. Down-regulation of USP9X could increase PIK3CA ubiquitination level. WP1130, a small molecule inhibitor of USP9X, has the same effect as knockdown of USP9X, both of which could increase the ubiquitination level of PIK3CA and reduce the protein level of PIK3CA. Conclusion The miR-15b-5p/USP9X/PIK3CA/AKT1 signaling pathway may provide potential therapeutic targets for asthma.

Nucleotide analogues (NAs) and interferon are still the first-line drugs for the treatment of chronic hepatitis B (CHB), but they still cannot completely eliminate covalently closed circular DNA (cccDNA) within hepatocytes. The clinical cure, or the disappearance of HBsAg, is the ideal goal of antiviral therapy. Although interferon therapy has a significantly greater HBsAg clearance rate and seroconversion rate than NAs, combination or sequential treatment can improve the HBsAg clearance rate and seroconversion rate to a certain extent, and only a small proportion of CHB patients can achieve clinical cure. Therefore, finding indications that predict clinical cure before and during antiviral treatment is crucial for identifying patients who are more likely to achieve HBsAg clearance at an early stage, improving clinical cure rates, and reducing treatment costs. This article reviews the research progress on predictive indicators of clinical cure of chronic hepatitis B in the past five years, explores the value of each indicator in predicting clinical cure, and provides a reference for optimizing CHB treatment strategies.

ObjectiveTo explore the current situation and influencing factors of humanistic care experience among patients visiting traditional Chinese medicine (TCM) outpatient clinics in China, and to provide a basis for optimizing TCM-characterized services in both TCM and Western medicine hospitals. MethodsA multi-center cross-sectional study was conducted using convenience sampling to select 35 hospitals across 13 provinces in China (including 3 TCM hospitals and 32 TCM outpatient clinics in general hospitals). A total of 3,430 patients were surveyed using the general information questionnaire and the Outpatient Humanistic Care Experience Questionnaire, with data collected via Questionnaire Star. Univariate analysis and multiple linear regression were employed to examine the impacts of patient characteristics, visit characteristics, hospital type (TCM hospital/general hospital), and geographic region (eastern/central/western) on humanistic care experience. ResultsThe total score of humanistic care experience was 194 (188, 233). Univariate analysis showed that gender, educational level, current residence, per capita monthly household income, location attribute of medical institutions, number of previous visits to this hospital, payment method of medical expenses, previous hospitalization history in this hospital, frequency of outpatient visits within the past 12 months, self-rated disease severity, familiarity with the outpatient procedures, implementation of the follow-up service provided by the hospital, satisfaction with follow-up services, the grade of the hospital visited, geographical region of the hospital visited, and the department visited had an impact on the humanistic care experience during outpatient visits (P<0.05). Multivariate analysis demonstrated that educational level (β=0.609, P=0.011), self-rated disease severity (β=-0.646, P=0.047), familiarity with outpatient procedures (β=4.784, P<0.001), satisfaction with follow-up services (β=6.365, P<0.001), and the grade of the hospital visited (β=-5.487, P<0.001) affected the humanistic care experience in outpatient medical treatment, explaining 24.4% of the total variation. ConclusionHumanistic care experience in TCM outpatient clinics is influenced by multiple factors. It is recommended to optimize the medical treatment process, strengthen doctor-patient communication training, and establish a precise follow-up mechanism, with a focus on improving care perceptions among patients with lower education levels and those attending primary-level hospitals, to refine the TCM-characterized service system.

Objective:To investigate the supervisor-student relationship experience of nursing postgraduates from the perspective of humanistic care, identify the influencing factors for students' care experience, and provide a reference for building a good supervisor-student relationship pattern with humanistic care.Methods:Objective sampling was used to enroll 15 nursing postgraduates from colleges and universities in Wuhan, Hubei Province, Beijing, and Guangzhou, Guangdong Province. A semi-structured interview was then conducted in the students. Nvivo 12 software and the Colaizzi seven-step analysis method were used for sorting and analysis of the interview data.Results:Five themes and 15 sub-themes (namely, daily interpersonal interaction, academic interaction, emotional communication, internal growth, and professional literacy) were extracted. Among these themes, equal communication and mental health care were of particular concern to the students. The nursing postgraduates also expected their tutors to provide care in their daily life and help them develop three essential values.Conclusions:The supervisor-student relationship from the perspective of humanistic care is becoming more individualized and diversified. The tutors should provide multidimensional care to nursing postgraduates based on the students' personal characteristics. Meanwhile, they should focus on developing students' humanistic care abilities to cultivate high-level nursing professionals with a high humanistic care foundation.
