Pinellia ternata, belonging to the Pinellia genus within the Araceae family, is a medicinal plant due to its tubers. There are severe issues with unclear germplasm and mixed varieties in its cultivation, necessitating urgent new variety protection efforts. The distinctness, uniformity, and stability (DUS) testing of the plant variety is the basis for protecting new plant varieties, and the DUS test guidelines are the technical basis for DUS testing. To develop the DUS test guidelines for P. ternata, agronomic traits of 229 germplasm of P. ternata were observed and measured during its two growth stages over the years, and each character was graded and described. A total of 38 traits were selected as the test traits of the DUS test guideline for P. ternata. There were three plant traits, 19 leaf traits, six flower traits, two fruit traits, two tuber traits, five bulbil traits, and one ploidy trait. These traits could be divided into 22 quality characters, 12 quantitative characters, and four pseudo-quantitative characters, as well as seven groups, including plants, leaves, flowers, fruit, tubers, bulbils, and ploidy. By searching for standard traits, 10 standard varieties were ultimately determined. Preparing these guidelines will have great significance for reviewing and protecting P. ternata varieties, safeguarding breeders' rights, and promoting the development of the P. ternata industry.

AIM: To investigate the specific molecular mechanism of Yinqiao Powder in affecting macrophage polarization in herpes simplex keratitis(HSK)through the cyclic GMP-AMP synthetase(cGAS)-stimulator of interferon genes(STING)-interferon regulatory factor 3(IRF3)molecular pathway.METHODS:Human corneal epithelial cells(HCE-T)were divided into control, HSK, and HSK + Yinqiao Powder groups. M0 macrophages were grouped as Ctrl, HSV-1, HSV-1+oe-cGAS, HSV-1+Yinqiao Powder, and HSV-1+oe-cGAS+Yinqiao Powder. Conditional medium(CM)from each group of M0 macrophages was collected to intervene in HCE-T cells and divided into Ctrl-CM, HSV-1-CM, HSV-1+oe-cGAS-CM, and HSV-1+Yinqiao Powder-CM groups. Cell viability was detected by MTT assay, and apoptosis was detected by TUNEL assay. ELISA was used to detect the concentrations of Arg-1 and iNOS in cell supernatants, and Western blotting was used to detect the relative protein expressions of cGAS, STING, and IRF3. Balb/c mice were divided into control, model, and drug groups. The model and drug groups were inoculated with HSV-1 on the cornea of Balb/c mice using the corneal scratch method to construct an HSK mouse model, and the drug group was treated with Yinqiao Powder. The incidence and mortality of the three groups were compared on days 1, 3, 5, 7, and 14 after modeling.RESULTS:Compared with the control group, the HCE-T cell viability in the HSK group was decreased but apoptosis was increased, which was reversed by Yinqiao Powder intervention. Compared with the Ctrl group, the Arg-1 concentration in the cell supernatant of the HSV-1 group was decreased, the iNOS concentration was increased, and the protein expressions of cGAS, STING, and IRF3 were decreased. Compared with the HSV-1 group, the Arg-1 concentration was increased, the iNOS concentration was decreased, and the protein expressions of cGAS, STING, and IRF3 were enhanced in the HSV-1+oe-cGAS group and the HSV-1+Yinqiao Powder group, and the same results were obtained in the HSV-1+oe-cGAS+Yinqiao Powder group. Compared with the Ctrl-CM group, the HCE-T cell viability was decreased and apoptosis was increased in the HSV-1-CM group, which was reversed by overexpressing cGAS in macrophages or intervening with Yinqiao Powder. In vivo experiments found that Yinqiao Powder intervention could improve the pathological progression of keratitis.CONCLUSION:Yinqiao Powder inhibits M1 polarization of macrophages through the cGAS-STING-IRF3 molecular pathway, thereby delaying the progression of HSK.

Artemisia argyi (A. argyi), a plant with a longstanding history as a raw material for traditional medicine and functional diets in Asia, has been used traditionally to bathe and soak feet for its disinfectant and itch-relieving properties. Despite its widespread use, scientific evidence validating the antifungal efficacy of A. argyi water extract (AAWE) against dermatophytes, particularly Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum gypseum, remains limited. This study aimed to substantiate the scientific basis of the folkloric use of A. argyi by evaluating the antifungal effects and the underlying molecular mechanisms of its active subfraction against dermatophytes. The results indicated that AAWE exhibited excellent antifungal effects against the three aforementioned dermatophyte species. The subfraction AAWE6, isolated using D101 macroporous resin, emerged as the most potent subfraction. The minimum inhibitory concentrations (MICs) of AAWE6 against T. rubrum, M. gypseum, and T. mentagrophytes were 312.5, 312.5, and 625 μg·mL-1, respectively. Transmission electron microscopy (TEM) results and assays of enzymes linked to cell wall integrity and cell membrane function indicated that AAWE6 could penetrate the external protective barrier of T. rubrum, creating breaches ("small holes"), and disrupt the internal mitochondrial structure ("granary"). Furthermore, transcriptome data, quantitative real-time PCR (RT-qPCR), and biochemical assays corroborated the severe disruption of mitochondrial function, evidenced by inhibited tricarboxylic acid (TCA) cycle and energy metabolism. Additionally, chemical characterization and molecular docking analyses identified flavonoids, primarily eupatilin (131.16 ± 4.52 mg·g-1) and jaceosidin (4.17 ± 0.18 mg·g-1), as the active components of AAWE6. In conclusion, the subfraction AAWE6 from A. argyi exerts antifungal effects against dermatophytes by disrupting mitochondrial morphology and function. This research validates the traditional use of A. argyi and provides scientific support for its anti-dermatophytic applications, as recognized in the Chinese patent (No. ZL202111161301.9).

ObjectiveTo identify immunogenic cell death (ICD)-related genes in hepatocellular carcinoma (HCC), and to establish a scoring model based on these genes for predicting the prognosis and tumor microenvironment characteristics of HCC. MethodsThe Cancer Genome Atlas database was used to obtain HCC datasets, and heatmaps were used to display the expression of 57 ICD-related genes in HCC. A cluster analysis was conducted based on the expression of ICD-related genes, and two ICD subtypes (low and high ICD expression groups) were analyzed in terms of gene ontology enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, somatic mutation, and immune cell infiltration. The LASSO Cox regression risk model was constructed to evaluate its clinical application value, and a nomogram model was established to predict the 1-, 3-, and 5-year survival rates of patients. In addition, qRT-PCR was used to validate the expression levels of key genes in the model. The independent-samples t test was used for comparison between two groups, and the univariate and multivariate Cox regression analyses were used to determine prognostic factors among clinicopathological features. The Kaplan-Meier survival curve was used for prognostic analysis, and the Spearman rank correlation test was used for correlation analysis. ResultsThe low ICD expression group had a poorer prognosis, while the high ICD expression group had relatively favorable clinical outcomes (P=0.004). Further analysis showed that the high ICD expression group was associated with an immune-active microenvironment, and the genes were mainly enriched in immune-related pathways such as immunoglobulin receptor binding, hematopoietic cell lineage, and B cell receptor. The results of somatic mutation analysis showed that the high ICD expression group had higher expression levels of CD274, CTLA4, HAVCR2, TIGIT, PDCD1, and PDCD1LG2 (all P<0.05). A risk prediction model was established using 8 ICD-related genes, i.e., HSP90AA1, ATG5, BAX, PPIA, HSPA4, TLR2, TREM1, and LY96, and this model showed a good predictive value across different clinical characteristics. The univariate and multivariate Cox regression analyses showed that age and risk score were independent prognostic factors for overall survival in the training set (both P<0.05). The results of qRT-PCR showed that the relative expression levels of HSPA4 and REM1 in HCC tumor samples were significantly higher than those in adjacent tissue samples (both P<0.001). For the patients with an increase in ICD risk score, the ICD risk score was negatively correlated with γδT cells (r=-0.29, P<0.05), plasma cells (r=-0.3, P<0.05), and CD8+T lymphocytes (r=-0.37, P<0.05) and was positively correlated with memory B cells (r=0.38, P<0.05), resting dendritic cells (r=0.47, P<0.05), and M0 macrophages (r=0.49, P<0.05). ConclusionThis study identifies the ICD-related genes that are associated with the prognosis of HCC, which provides insights into the immune characteristics of different ICD expression profiles. The risk model and the nomogram model established in this study have a significant value for predicting the prognosis of HCC patients and guiding immunotherapy for HCC patients.

Objective:To investigate and analyze the employment status of college graduates majoring in health service and management in China.Methods:From April 2023 to June 2024, a cross-sectional survey was conducted on undergraduate graduates majoring in health service and management from 34 universities in China using convenient sampling method. General information was collected (such as gender, household registration at graduation, only child status, average monthly family income, previous experience as a student cadre, average grade point, part-time job experience, entrepreneurial experience, whether a first batch graduate of the university and the major, self-assessment of professional competence level) alongside employment status. Statistical descriptive analysis was employed to analyze the graduates′ basic employment situation, job competence and professional skill demand, types of certificates valued by employers, factors influencing job selection, evaluation of work and profession, and perceptions of professional employment prospects. A total of 1 417 questionnaires were collected in this study, with 1 315 valid responses (92.8%). Chi-square tests were used to compare employment differences among various factors, and binary logistic regression was used to analyze factors influencing employment outcomes.Results:Among 564 employed graduates in the Health Services and Management field, 98 (17.4%) work in health management companies and 97 (17.2%) in hospitals. Regarding important job competencies, 413 (73.2%), 409 (72.5%), and 364 (64.5%) respectively emphasized the importance of information collection and statistical analysis, organizational coordination, and communication skills. Key professional skills highly valued by employers included health risk assessment 175 (66.3%), health measurement 160 (60.6%), and health education and promotion 152 (57.6%). Additionally, 281 (49.8%) highlighted the importance of Health Management Professional Qualification Certificates. Factors influencing job choices included salary and benefits 454 (80.5%) and personal interests and hobbies 279 (49.5%). While 397 (70.4%) of the graduates provided positive feedback on their profession, only 274 (48.6%) were optimistic about their future job prospects. Binary logistic regression analysis indicated significant correlations (all P<0.05) between employment outcomes and factors such as part-time work experience ( OR=1.31) and average grade point ( OR=0.61, 0.68). Conclusions:The employment rate of undergraduate graduates majoring in health service and management in China is low in the health service market, with a low degree of job specialization matching. Graduates are not optimistic about the future employment prospects in their field, possibly due to unclear positioning in talent cultivation in universities and an imperfect job market.

BACKGROUND:
With the development of traditional Chinese medicine research, berberine has shown good efficacy and safety in the eradication of Helicobacter pylori (H. pylori). The present study aimed to evaluate the efficacy and safety of triple therapy containing berberine, amoxicillin, and vonoprazan for the initial treatment of H. pylori.
METHODS:
This study was a single-center, open-label, parallel, randomized controlled clinical trial. Patients with H. pylori infection were randomly (1:1:1) assigned to receive berberine triple therapy (berberine 500 mg, amoxicillin 1000 mg, vonoprazan 20 mg, A group), vonoprazan quadruple therapy (vonoprazan 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, B group), or rabeprazole quadruple therapy (rabeprazole 10 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, C group). The drugs were taken twice daily for 14 days. The main outcome was the H. pylori eradication rate. The secondary outcomes were symptom improvement rate, patient compliance, and incidence of adverse events. Furthermore, factors affecting the eradication rate of H. pylori were further analyzed.
RESULTS:
A total of 300 H. pylori-infected patients were included in this study, and 263 patients completed the study. An intention-to-treat (ITT) analysis showed that the eradication rates of H. pylori in berberine triple therapy, vonoprazan quadruple therapy, and rabeprazole quadruple therapy were 70.0% (70/100), 77.0% (77/100), and 69.0% (69/100), respectively. The per-protocol (PP) analysis showed that the eradication rates of H. pylori in these three groups were 81.4% (70/86), 86.5% (77/89), and 78.4% (69/88), respectively. Both ITT analysis and PP analysis showed that the H. pylori eradication rate did not significantly differ among the three groups (P >0.05). In addition, the symptom improvement rate, overall adverse reaction rate, and patient compliance were similar among the three groups (P >0.05).
CONCLUSIONS
The efficacy of berberine triple therapy for H. pylori initial treatment was comparable to that of vonoprazan quadruple therapy and rabeprazole quadruple therapy, and it was well tolerated. It could be used as one choice of H. pylori initial treatment.
