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.

Sacroiliac complex injuries are commonly seen in high-energy pelvic fractures. The injuries make a big difference in treatment patterns due to the diverse injury types, posing considerable challenges in formulating optimal treatment strategies, and hence are persistent clinical difficulties in orthopedic trauma. The clinical management of sacroiliac complex injuries presents several key challenges such as a non-negligible rate of missed diagnoses in associated vascular and visceral injuries, absence of standardized protocols for surgical approaches and reduction-fixation strategies across different injury patterns, and ongoing controversies regarding surgical indications and optimal timing for patients combined with concomitant lumbosacral plexus injuries. Currently, no systematic clinical guidelines are available for the diagnosis and treatment of sacroiliac complex injuries both domestically and internationally. To this end, the Pelvic and Acetabular Surgery Group, Orthopedic Branch, China International Exchange and Promotive Association for Medical and Health Care and Orthopedic Physician Branch, Chinese Medical Doctor Association organized a panel of domestic experts in the field to develop the Clinical guideline for the diagnosis and treatment of sacroiliac complex injuries ( version 2025), based on evidence-based medicine and adhering to the principles of scientific rigor, clinical applicability, and innovation. These guidelines provided 11 recommendations covering diagnosis, therapeutic principles and techniques, management protocols for lumbosacral plexus injuries, outcome evaluation, and postoperative rehabilitation pathways, etc., aiming to standardize the clinical management of sacroiliac complex injuries.

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.

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).

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.

Objective:To investigate the clinical efficacy of robot-assisted minimally invasive sacroiliac screw fixation combined with LC-II external fixation in the treatment of pelvic fracture.Methods:A retrospective analysis was conducted on 28 cases with pelvic fractures treated with robot-assisted minimally invasive sacroiliac screw fixation combined with LC-II external fixation from May 2018 to November 2022. There were 19 males and 9 females, with an average age of 43.4±16.9 years (range, 14-74 years). There was 1 case of B1 type, 1 case of B2 type, 4 cases of B3 type, 10 cases of C1 type, 9 cases of C2 type and 3 cases of C3 type by Tile classification. All the cases were treated with closed reduction, LC-II external fixation for the anterior lesions and robot-assisted minimally invasive sacroiliac screw fixation for the posterior lesions. The operation time, fluoroscopy time and excellent rate of screw placement were recorded. The quality of fracture reduction was evaluated by Matta's criteria, and the clinical effect was evaluated by Majeed score.Results:All the 28 cases successfully underwent the surgery. In 11 cases the fractures were reduced by the pelvic unlocking closed reduction device while in the other 17 cases manual reduction was applied. In this cohort, 43 screws were implanted. All the screw positions reached level I by Gras grading. The average fluoroscopy time was 16.3±5.2 s (range, 9-31 s) per screw. The average operation time was 154.9±54.7 min (range, 55-226 min). According to the Matta's criteria, the reduction was rated as excellent in 19 cases, good in 7 cases, fair in 2 cases, yielding an excellent or good rate of 93% (26/28). No iatrogenic neurovascular injury was found in all the 28 patients. The average follow-up was 18.3±7.3 months (range, 4-31 months). The fractures healed at 3.6±1.1 months (range, 2-6 months) after the surgeries. At the final follow-up, the results of the Majeed scores were rated as excellent in 13 cases, good in 11 cases, fair in 3 cases and poor in 1 case, with an excellent or good rate of 86% (24/28).Conclusion:The technique of robot-assisted minimally invasive sacroiliac screw fixation combined with LC-II external fixation used in the treatment of pelvic fracture showed good clinical results.
