Objective:
To analyze the space time characteristics of poor vision among primary and secondary school students in Chengdu, in order to provide the reference for formulating myopia prevention and control policies for students.
Methods:
The data relating to poor vision among primary and secondary school students in Chengdu from 2021 to 2023 were sourced from the Sichuan Students Physical Health Big Data Center. The districts and counties of Chengdu were divided into three circles, including the main urban area, suburban districts and counties, and suburban districts and counties. The Chi square test was used for inter group comparison, and the Cochran-Armitage test was used to analyze the trend of changes. Global and local Moran s I were used to analyze spatial clustering.
Results:
The detection rates of poor vision among primary and secondary school students in Chengdu from 2021 to 2023 were 62.47%, 61.61% and 60.78%, respectively, showing a decreasing trend ( Z=-32.01, P <0.01). For each year, the higher detection rate of poor vision among students was detected in the higher level of education, and differences were statistically significant ( χ 2=161 549.47, 173 471.87, 233 459.09, P <0.01). The rate of poor vision among primary and secondary school students gradually decreased from the central districts and counties of Chengdu to the surrounding districts and counties for each year, and the differences were statistically significant ( χ 2=299.20, 776.22, 633.16, P <0.01). The spatial autocorrelation analysis showed that the first circle of Chengdu City was mainly characterized by high-high agglomeration ( P <0.01), with the rate of poor vision among primary school students in Wuhou District in 2023 exhibiting a low-high anomaly. The third circle was mainly characterized by low-low aggregation ( P <0.01), while the spatial clusterings of the second circle was not significant ( P >0.05).
Conclusions
The myopia prevention and control work in Chengdu has achieved preliminary results. It should continue to consolidate existing achievements and implement targeted myopia prevention and control measures based on regional characteristics.

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.

ObjectiveTo explore the genetic relationship and reveal the genetic variations of 45 germplasm accessions of Artemisia argyi. MethodGenotyping-by-sequencing (GBS) was employed to mine single nucleotide-polymorphisms (SNPs) from the 45 germplasm accessions. Principal component analysis, phylogenetic analysis, population genetic structure analysis, and genetic variation analysis were conducted based on the SNPs. ResultA total of 111.91 Gb of data were obtained, with the Q20, Q30, and average GC content of 96.39%, 90.33%, and 39.37%, respectively. The comparison rate between clean reads and the reference genome was 70.24%-98.97%. A total of 22 399 Indels and 170 539 SNPs were obtained, and the 10th pair of chromosomes had the most variation sites. The results of principal component analysis, cluster analysis, and genetic diversity analysis classified the 45 germplasm accessions into three groups. Group Ⅰ contained three germplasm accessions from Qichun County. The germplasm accessions in group Ⅱ were all wild. Group Ⅲ contained 31 germplasm accessions, with the most complex sources. Moreover, the 45 germplasm accessions can be classified into 3 subtypes, containing the genetic information from three ancestors. The results indicated rich genetic diversity of A. argyi from different sources, especially the germplasm accessions from Qichun County, Hubei province. ConclusionThis study provides theoretical support for breeding new varieties, developing specific SNP markers, and revealing the genetic relationship of A. argyi.

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).

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.

ObjectiveTo evaluate the clinical safety of Naoxintong (NXT) capsules after marketing, find out the potential risk factors of the drug as soon as possible, and reveal the incidence, nature, and clinical manifestations of the adverse events (ADE) and adverse reactions (ADR) of NXT capsules, so as to provide a basis for safe use of the drug in clinical practice. MethodA prospective, large-sample, multi-center observational cohort study was conducted to monitor all the 7 345 inpatients and outpatients orally taking NXT in 14 hospitals in China from January to December in 2018, with at least one follow-up. The demographic characteristics, disease type, NXT medication, ADR occurrence, characteristics, and prognosis of the patients were collected. SPSS 23.0 was used for single-factor and multivariate logistic regression to predict the influencing factors of ADR. ResultThe male and female patients accounted for similar proportions. There were 5 081 patients (79.40%) aged ≥60 years and 3 153 patients (49.27%) with body mass index (BMI) exceeding the normal standard. There were 344 (5.38%) patients with a history of allergy to medicines and food, 9 (0.14%) patients with a family history of allergy, and 52 (0.81%) patients with a history of allergic diseases. The ADRs associated with NXT occurred in 22 patients, with the incidence of 0.34%. The clinical manifestations of ADR appeared in 31 cases, involving 10 organs/systems, of which gastrointestinal system damage was the most common (17, 54.84%). All ADRs were mild or moderate. Most ADRs (19, 86.36%) occurred within 4 weeks after administration. The patients with alleviated NXT-associated ADRs accounted for 81.82%. No indicators related to significant increases in ADR risks were found. ConclusionNXT is well tolerated in the general population. The hospital centralized monitoring for the clinical safety of oral Chinese patent drugs based on HIS data and Web tracking and follow-up system is an essential means for the post-market research on the safety of drugs.
