AIM: To investigate the research status and hotspots in the field of ocular trauma over the past two decades using bibliometric software CiteSpace and VOSviewer.METHODS: A bibliometric study. Relevant literature on ocular trauma published in the past 20 a was retrieved from the CNKI database and Web of Science Core Collection in June 2025. EndNote X9 was used for literature management and verification. Microsoft Office Excel 2019 was employed for data management and statistics, with graphical representations created for frequency data. CiteSpace and VOSviewer were utilized to construct and analyze visual maps of authors, institutions, countries/regions, journals, and keywords.RESULTS: A total of 3 437 valid articles were included(911 in Chinese, 2 526 in English). English publications grew at an average annual rate of 12.7%(peak: 289 articles in 2021), while Chinese articles decreased from 31.2% in 2005(peak: 149 articles)to 6.3% in 2024. Chinese scholars showed an early surge in output but a subsequent declining trend, necessitating enhanced sustained research investment and translational outcomes. The United States(682 articles), China(272 articles), and India(206 articles)formed a core collaborative triangle, with a transnational collaboration rate of 68.2%. Six author clusters(e.g., Yan Hua/Zhang Maonian, et al.)demonstrated strong intra-group collaboration but minimal inter-group cooperation. Analysis of high-frequency keywords and burst terms revealed six global research hotspots: 1)ocular trauma score and minimally invasive vitrectomy; 2)optical coherence tomography(OCT)/ultrasound biomicroscopy(UBM)-guided diagnosis and management of intraocular foreign bodies; 3)amniotic membrane transplantation for chemical injury repair; 4)multimodal assessment of corneal perforation injuries; 5)inflammatory indicators for diagnosing endophthalmitis as a traumatic complication; 6)family-based interventions for preventing and controlling pediatric ocular trauma. Trends indicate a shift in research focus from emergency care toward artificial substitutes and full-cycle nursing rehabilitation.CONCLUSION: Differences in research outputs between China and other countries reflect imbalances in prevention policies and medical resource allocation. China should strengthen sustained investment and overcome collaboration barriers to jointly advance ocular trauma research toward full-cycle precision management.

OBJECTIVE To observe the effects of Panax quinquefolium-Acorus calamus on learning and memory abilities in diabetes mellitus(DM) mice and investigate the mechanism of Panax quinquefolium-Acorus calamus in treating diabetic cognitive impairment(DCI) through network pharmacology and animal experiments. METHODS Diabetic mouse model was established by intraperitoneal injection of streptozotocin(80 mg·kg−1), followed by 8 weeks of oral administration and assessment of drug efficacy using the Morris water maze. The active ingredients and targets of Panax quinquefolium-Acorus calamus were collected using TCMSP, Swiss Target Prediction, and Gene Cards. The protein-protein interaction network of "Traditional Chinese Medicine-Ingredient-Disease targets" was constructed using the String platform and Cytoscape, visualized, and subjected to enrichment analysis using the Metascape database. The anti-DCI mechanism of Panax quinquefolium-Acorus calamus was examined through ELISA and Western blotting, while changes in hippocampal neurons of diabetic mice were observed using HE staining. RESULTS Panax quinquefolium-Acorus calamus reduced the escape latency of diabetic mice(P<0.05), without significant impact on swimming speed. Network pharmacology results indicated that the main components of Panax quinquefolium-Acorus calamus in treating DCI were ginsenoside Re, ginsenoside Rh2, and shanjin phenol, which regulated the Nrf2-Keap1 signaling pathway to treat DCI. Animal experiments demonstrated that Panax quinquefolium-Acorus calamus increased SOD activity(P<0.05), decreased MDA levels(P<0.01), enhanced the expression of HO-1, Keap1, Nrf2 in mouse brain(P<0.01), and alleviated the loosening of granule cell arrangement and nuclear condensation in the hippocampal CA1, CA3, and DG regions. CONCLUSION Using animal experiments combined with network pharmacology, this study preliminarily elucidates the potential targets and mechanisms of Panax quinquefolium-Acorus calamus in intervening DCI, and predictes the molecular basis for its intervention in DCI through molecular docking, providing insights for further in-depth research on Panax quinquefolium-Acorus calamus.

The blood and fecal samples were collected before surgery and then subjected to biochemical tests for tumor markers and 16S rDNA tests, respectively. SPSS (27.0.1) was applied to perform the t-test, one-way ANOVA, Mann-Whitney U test, Kruskal-Wallis H test, and Chi-Squared Test. Also, the receiver operating characteristic curve (ROC) was plotted on tumor markers and/or f_Bacteroidaceae with SPSS software .Results:All groups had significant differences in the CA125 ( F=3.543, P<0.05), CA72-4 ( F=3.596, P<0.05), and serum tumor-associated materials (TAM) levels ( F=5.787, P<0.01). In PC group, the levels of CA125 [PC vs RC, (36.84±6.30) kU/L vs (12.73±4.21) kU/L, P<0.01] and CA72-4 [PC vs RC, (45.56±10.86) kU/L vs (3.30±7.63) kU/L, P<0.01] were significantly higher than that of the RC group, while the level of TAM was remarkably elevated in PC group than in RC group [PC vs RC, (124.84±5.19) U/ml vs (102.44±3.63) U/ml, P<0.001] and CRA group [PC vs CRA, (124.84±5.19) U/ml vs (95.39±8.42) U/ml, P<0.01]. The LEfSe analysis showed that the featured microbiota in the PC group included f_Bacteroidaceae, f_Neisseriaceae, f_Clostridiaceae_1, f_Spirochaetaceae, and so on. The largest area under the ROC belonged to the combination of TAM and f_Bacteroidaceae, which reached 0.845 (95% CI 0.747-0.944), with sensitivity being 0.857 and specificity being 0.815. Conclusions:There is heterogeneity in gut microbiota composition among PC, DC, RC, and CRA. The combination of gut microbiota and tumor biomarkers demonstrated good differentiating effects in proximal colon cancers.

Objective:To establish a scientific and comprehensive evaluation index system for teaching ability of dental specialist nurses, providing a basis for the selection and assessment of dental nursing instructors.Methods:Based on literature analysis, semi-structured interviews, and group discussions, preliminary evaluation indicators were formulated. From February to April 2023, the Delphi method was used to conduct two rounds of consultation with 27 experts from six provinces and municipalities in China to determine the evaluation index system for the teaching ability of dental specialist nurses. The analytic hierarchy process (AHP) was used to determine the weights of each indicator and its combined weight.Results:The authority coefficient of 27 experts was 0.895. In the two rounds of expert consultation, the effective response rates of the questionnaire were all 100% (27/27), and the Kendall harmony coefficients of various indicators were 0.179 to 0.240 and 0.200 to 0.261 respectively ( P<0.01). The final evaluation index system for teaching ability of dental specialist nurses was formed, including six primary indicators, 15 secondary indicators, and 71 tertiary indicators. Conclusions:The evaluation index system for teaching ability of dental specialist nurses has a reasonable structure, a scientific and rigorous construction process, and can provide a theoretical basis for the allocation of dental specialist human resources and nursing training assessment.

Objective:To comprehensively and systematically retrieve domestic and international research on nurse-initiated protocolized weaning in adult mechanically ventilated patients, clarify its outcome indicators and effectiveness in clinical practice, and identify influencing factors in its implementation.Methods:Employing the scoping review methodology of Arksey and O'Malley, databases in both English and Chinese were systematically searched. Literature was selected based on inclusion and exclusion criteria, with two researchers independently screening, organizing, and analyzing the articles.Results:Eighteen publications were included: seven interventional studies, four qualitative studies, two cross-sectional studies, two on instrument development, and three reviews. Nurse-initiated protocolized weaning was found to be safe and effective, with common clinical outcome indicators including mechanical ventilation duration, weaning time, and ICU length of stay. Significant barriers included the professional knowledge level of nurses, team cooperation, nurses' personal characteristics, and the healthcare providers' underestimation of patients' clinical symptoms. Continuous care, patient involvement, a supportive nursing culture, and recognition of the nurse's role were facilitators of this treatment.Conclusions:Future research efforts should standardize and refine the intervention measures of nurse-initiated protocolized weaning and conduct large-sample, high-quality studies to provide references for the implementation of nurse-initiated protocolized weaning in China.

Objective To construct a mouse model of psoriasis with spleen deficiency and dampness obstruction pattern and evaluate the model from multiple dimensions and directions,expects to provide research support for the study of traditional Chinese medicine (TCM) treatment of psoriasis with spleen deficiency and dampness obstruction pattern. Methods A mouse model of spleen deficiency and dampness obstruction pattern was established by feeding a high-fat diet,a mouse model of psoriasis vulgaris was established by externally applying imiquimod ointment,and a mouse model of psoriasis with spleen deficiency and dampness obstruction pattern was constructed by combining the above two models. Indications of spleen deficiency and dampness obstruction pattern were evaluated by comparing the body mass,food intake and water intake of mice in each group. The severity of psoriasis in mice was evaluated by comparing the area of skin lesions,PASI score,the value of transdermal water loss (TEWL),and histopathological morphological changes of skin under HE staining in each group. Flow cytometry was used to detect the expression in various cell types to evaluate the degree of inflammatory response of psoriasis in mice. Observation of adiposity index,changes in the histopathological morphology of liver tissue under HE staining,changes in the mRNA expression levels of related factors in liver tissue and adipose tissue of epididymis of mice detected by RT-qPCR,and changes of ABCA1 protein expression level of skin detected by Western Blot were used to evaluate the lipid metabolism disorders in mice. Results Compared with the mice in the psoriasis vulgaris model group,the mice in the model of psoriasis with pattern of spleen deficiency and dampness obstruction had significantly higher body mass (P<0.001),significantly lower food intake (P<0.005),and the symptoms of pattern of spleen deficiency and dampness obstruction such as greasy fur,mental fatigue,etc. appeared. The TWEL were significantly increased(P<0.001),and the PASI scores also significantly increased(P<0.001). HE results were found psoriasis-like manifestations including hypertrophy of the spinous layer and clubbed hyperplasia. The expression of CD11bhighLy6G+neutrophil subpopulation,CD11binLy6Chigh monocyte subpopulation,CD11binCD11chigh classical dendritic cell subpopulation,F4/80-CD11c+dendritic cell subpopulation was significantly increased (P<0.001). HE staining suggested that the cellular morphology of liver showed obvious vacuolated degeneration,and the index of subcutaneous white adiposity and epididymal adiposity index were both significantly increased (P<0.005). The mRNA levels of FABP4 and CD36 in liver tissue were significantly elevated(P<0.005,P<0.001),while the mRNA expression levels of ABCA1 and PPARγ in epididymal fat tissue were decreased (P<0.05,P<0.01). ABCA1 protein level in skin increased(P>0.05). Conclusion The mouse model of psoriasis with spleen deficiency and dampness obstruction pattern can be used as a reliable animal model for combining disease and pattern,which can provide a reference for further exploration of TCM in the treatment of psoriasis with spleen deficiency and dampness obstruction pattern.

OBJECTIVE: To review the research progress of rapid surgery for hip fracture in elderly patients. METHODS: The published studies, expert consensus, and guidelines at home and abroad were systematically summarized from the aspects of the characteristics of aging population, the benefits of rapid surgery, the disadvantages of delayed surgery, and the recommendations of current guidelines, so as to further guide clinical practice. RESULTS: Hip fracture is a common fracture type in the elderly population. As elderly patients generally have poor physique and often have a variety of underlying diseases, such as hypostatic pneumonia, bedsore, lower limb vein thrombosis, and other complications in conservative treatment, its disability rate and mortality are high, so surgical treatment is the first choice. At present, most relevant studies and expert consensus and guidelines at home and abroad support rapid surgery, that is, preoperative examination should be started immediately after admission, and adverse factors such as taking anticoagulant drugs, serious cardiovascular diseases, and severe anemia should be clearly and actively corrected, and surgery should be completed within 48 hours after admission as far as possible. Rapid surgery can not only significantly reduce the mortality of patients, but also reduce the length of hospital stay and the incidence of perioperative cognitive impairment, which is conducive to the recovery of patients with pain during hospitalization and postoperative function, and improve the prognosis of patients. CONCLUSION In order to avoid many problems caused by delayed surgery, the elderly patients with hip fracture should be operated as soon as possible under the condition of actively correcting the adverse factors. Comprehensive evaluation and preparation, the development of an individualized surgical plan, and the formation of a multidisciplinary medical team can reduce surgical risks and improve effectiveness.

Objective:To measure the crown conical degree of the remaining maxillary incisors in patients with congenital tooth agenesis, and to analyze the influence of different gene mutations on the crown conical degree of patients.Methods:Whole exome sequencing was performed on 85 patients with congenital tooth agenesis (50 males, 35 females, median age 19 years old) who visited the Department of Prosthodontics, Peking University School and Hospital of Stomatology from January 2019 to January 2023. The pathogenic gene was identified. The width of the crowns of the maxillary central and lateral incisors at the incisal 1/3 and gingival 1/3 were measured on the panoramic radiograph, and the ratio was defined as the crown conical degree. The smaller the ratio is, the more likely is the crown to be peg shaped teeth. The control group was matched by age and gender with 85 other patients with intact maxillary permanent incisors who were treated in the Department of Prosthodontics, Peking University School and Hospital of Stomatology from January 2019 to January 2023. The conical degree of the tooth agenesis group was compared with the control group by t-test, and the differences in the crown conical degree in different gene mutation groups were compared using one-way analysis of variance, and the multiple comparisons among gene groups were carried out using the LSD method.Results:Among the 85 tooth agenesis patients, the numbers of patients in each gene mutation group were 20 in ectodysplasin A (EDA) group, 8 in ectodysplasin A receptor (EDAR) group, 15 in wingless-type MMTV integration site family, member 10A (WNT10A) group, 16 in paired box 9 (PAX9) group, 10 in Msh homeobox 1 (MSX1) group, 10 in low-density lipoprotein receptor related protein 6 (LRP6) group, and 6 in bone morphogenetic protein4 (BMP4) group. The number of missing teeth were 1-27, median number 15 among the tooth agenesis patients. There was no significant difference in the conical degree between the left and right homonymous teeth in the congenital tooth agenesis group and the control group ( P>0.05). The crown conical degree of maxillary central incisor and lateral incisor in the congenital missing teeth group (0.95±0.24, 0.90±0.22) was significantly smaller than that in the control group (1.12±0.09, 1.13±0.09) ( t=-8.50, P<0.001; t=-11.47, P<0.001). In WNT10A mutants, the conical degree of lateral incisors (0.89±0.18) was less than that of central incisors (1.07±0.15)( t=3.68, P<0.001). The conical degree of central incisors and lateral incisors (0.70±0.23, 0.57±0.15) of EDA mutants was significantly lower than that in patients with other gene mutations ( P>0.05). Conclusions:Compared with the normal control group, the remaining maxillary central and lateral incisors of the seven gene mutation groups of patients with congenital tooth agenesis all had different degrees of conical crown. Among them, the crown conical degree of maxillary central and lateral incisors of the EDA mutation was the most severe, and the WNT10A mutation affected the maxillary lateral incisors more specifically.

Objective:To develop the Oral Health Protective Motivation Questionnaire for Adults and test its reliability and validity.Methods:This study is a cross-sectional study. The initial version of Oral Health Protective Motivation Questionnaire for Adults was constructed based on the protection motivation theory, referring to the Oral Health Guideline for Chinese Population, through literature review, semi-structured interviews and expert consultation. From March to April 2022, 610 adults from 6 communities in Qingdao were selected by convenient sampling to conduct a questionnaire survey. The questionnaire was initially evaluated by item analysis and reliability and validity testing. A total of 610 questionnaires were distributed, and 599 valid questionnaires were recovered, with a valid recovery rate of 98.20% (599/610) . Results:The Oral Health Protective Motivation Questionnaire for Adults included 35 items. Exploratory factor analysis extracted six common factors, namely severity, susceptibility, internal and external rewards, response cost, response efficacy, and self-efficacy, the explanatory variation of each factor was 60.28% to 74.23%. Confirmatory factor analysis showed that the six factors model fitted well. Cronbach's α coefficient of the total questionnaire was 0.946, and the Cronbach's α coefficient of each dimension was from 0.744 to 0.937. The half-reliability coefficient of the total questionnaire was 0.853.Conclusions:The Oral Health Protective Motivation Questionnaire for Adults has good reliability and validity, and can be used to evaluate the adult oral health protection motivation.
