BACKGROUND:Ossification of the ligamentum flavum was previously considered to be rare in the population.As research has progressed,its incidence rate is increasing gradually,which has aroused the interest of a large number of researchers. OBJECTIVE:To visualize and analyze the research results on ossification of the ligamentum flavum from the Web of Science Core Collection since 1999 using bibliometric methods,and to review the research history of ossification of the ligamentum flavum,highlighting important literature,summarizing research hotspots,and providing ideas for researchers to find research directions. METHODS:Using the Web of Science Core Collection as the data source,relevant papers on ossification of the ligamentum flavum were searched and screened.VOSviewer 1.6.19 and CiteSpace 6.2.R6 were used to conduct the visual analysis of annual publication volume,research countries,institutions,citations,journals,authors,and keywords. RESULTS AND CONCLUSION:(1)A total of 347 papers were included.Since 1999,the number of published papers has increased in a spiral pattern.China's research started later than Japan's,but the number of publications has come up later,with Peking University being the institution with the most publications,and Prof.Chen Zhongqiang from Peking University being the scholar with the most publications.(2)Five of the 10 most frequently cited publications were related to the surgical treatment of the disease.(3)Excluding keywords directly related to the research topic and synthetically analyzing frequencies and betweenness centralities of key words,terms such as"thoracic myelopathy,""dural ossification,""minimally invasive surgery,"and"ossification of the posterior longitudinal ligament"occupied a central position in this field.(4)Keywords clustering analysis showed that clinical manifestations and surgical treatment of ossification of the ligamentum flavum accounted for a large proportion of study.(5)The timeline and burst analysis of keywords revealed that"minimally invasive surgery"appeared as a keyword around 2015,with the highest burst strength and the latest burst start time,and began to receive extensive attention from researchers in 2019.The burst of the keyword"dural ossification"has not yet ended.(6)Surgical treatment for ossification of the ligamentum flavum has been at the forefront of research.Development and research of minimally invasive surgery and research on dural ossification secondary to ossification of the ligamentum flavum are both current research hotspots and possible future research trends.

ObjectiveTo analyze the data structure and standards of rehabilitation outpatient medical records, to provide data support for improving the quality of rehabilitation outpatient care and developing medical insurance payment policies. MethodsBased on the normative documents issued by the National Health Commission, Basic Standards for Medical Record Writing and Standards for Electronic Medical Record Sharing Documents, in accordance with the Quality Management Regulations for Outpatient (Emergency) Diagnosis and Treatment Information Pages (Trial), reference to the framework of the World Health Organization Family of International Classifications (WHO-FICs), the data framework and content of rehabilitation outpatient medical records were determined, and the data standards were discussed. ResultsThis study constructed a data framework for rehabilitation outpatient medical records, including four main components: patient basic information, visit process information, diagnosis and treatment information, and cost information. Three major reference classifications of WHO-FICs, International Classification of Diseases, International Classification of Functioning, Disability and Health, and International Classification of Health Interventions,were used to establish diagnostic standards and standardized terminology, as well as coding disease diagnosis, functional description, functional assessment, and rehabilitation interventions, to improve the quality of data reporting, and level of quality control in rehabilitation. ConclusionThe structuring and standardization of rehabilitation outpatient medical records are the foundation for sharing of rehabilitation data. The using of the three major classifications of WHO-FICs is valuable for the terminology and coding of disease diagnosis, functional description and assessment, and intervention in rehabilitation outpatient medical records, which is significant for sharing and interconnectivity of rehabilitation outpatient data, as well as for optimizing the quality and safety of rehabilitation medical services.

ObjectiveTo explore the standardization of inpatient rehabilitation medical record summary sheet, encompassing its structure, content and data standards, to enhance the standardization level of inpatient rehabilitation medical record summary sheet, improve data reporting quality, and provide accurate data support for medical insurance payment, hospital performance evaluation, and rehabilitation discipline evaluation. MethodsBased on the relevant specifications of the National Health Commission's Basic Norms for Medical Record Writing, Specifications for Sharing Documents of Electronic Medical Records, and Quality Management and Control Indicators for Inpatient Medical Record Summary Sheet (2016 Edition), this study analyzed the structure and content of the inpatient rehabilitation medical record summary sheet. The study systematically applied the three major reference classifications of the World Health Organization Family of International Classifications, International Classification of Diseases (ICD-10/ICD-11, ICD-9-CM-3), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), for disease diagnosis, functional description and assessment, and rehabilitation intervention, forming a standardized terminology system and coding methods. ResultsThe inpatient rehabilitation medical record summary sheet covered four major sections: inpatient information, hospitalization information, diagnosis and treatment information, and cost information. ICD-10/ICD-11 were the standards and coding tools for admission and discharge diagnoses in the inpatient rehabilitation medical record summary sheet. The three functional assessment tools recommended by ICD-11, the 36-item version of World Health Organization Disability Assessment Schedule 2.0, Brief Model Disability Survey and Generic Functioning domains, as well as ICF, were used for rehabilitation functioning assessment and the coding of outcomes. ICHI Beta-3 and ICD-9-CM-3 were used for coding surgical procedures and operations in the medical record summary sheet, and also for coding rehabilitation intervention items. ConclusionThe inpatient rehabilitation medical record summary sheet is a summary of the relevant content of the rehabilitation medical record and a tool for reporting inpatient rehabilitation data. It needs to be refined and optimized according to the characteristics of rehabilitation, with necessary data supplemented. The application of ICD-11/ICD-10, ICF and ICHI Beta-3/ICD-9-CM-3 classification standards would comprehensively promote the accuracy of inpatient diagnosis of diseases and functions. Based on ICD-11 and ICF, relevant functional assessment result data would be added, and ICHI Beta-3/ICD-9-CM-3 should be used to code rehabilitation interventions. Improving the quality of rehabilitation medical records and inpatient rehabilitation medical record summary sheet is an important part of rehabilitation quality control, and also lays an evidence-based data foundation for the analysis and application of inpatient rehabilitation medical record summary sheet.

Objective: To investigate the impact of disposable plastic food container usage on the executive function among primary school students, so as to provide the evidence for the formulation of relevant health policies. Methods: From November 2023 to May 2024, a convenience sampling method was employed to select 1 118 grade 1-3 students from three primary schools in a central district of Chongqing. A self developed questionnaire was used to collect demographic characteristics and data on disposable plastic food container usage. Executive function of primary school students was assessed using the Childhood Executive Functioning Inventory (CHEXI). Multivariate linear regression analysis was conducted to explore the associations between disposable plastic food container usage and heating with executive function among primary school students. Results: Median scores for working memory, inhibition and total executive function among primary school students were 32 (26, 39), 33 (28, 38), and 66 (54, 75), respectively. Multivariate linear regression analysis showed that among girls, higher frequencies of eating meals from plastic lunchboxes were associated with higher CHEXI working memory scores ( β =1.29), inhibition scores ( β =1.57), and total executive function scores ( β =2.85) ( P <0.05). Compared to girls who did not use plastic cups or drank bottled water, those who used plastic cups for drinking or drank bottled water had higher scores in working memory ( β =2.63), inhibition ( β =2.10), and total executive function ( β =4.73); compared to girls who did not eat canned food from metal cans, those who ate such food had higher scores in working memory ( β =3.62), inhibition ( β =1.89), and total executive function ( β =5.50) ( P <0.05).Among boys, higher frequencies of eating meals from plastic lunchboxes were associated with higher inhibition scores ( β =1.13) ( P <0.05). Compared to girls who ate with a plastic lunch box and did not heat it when they ate,girls who more frequent heating plastic lunchboxes with food inside had higher working memory scores ( β = 5.39), inhibition scores ( β =4.29), and total executive function scores ( β = 9.68) ( P <0.05). Conclusions The use of disposable plastic food containers may adversely affect executive function of primary school students, with a more pronounced effect observed in girls. Strengthened regulation of disposable plastic products and health education are urgently needed.

Objective: To explore whether infected granulation tissue in tooth extraction sockets and maxillary sinus pus share a common microbial profile at the subspecies-strain level in patients with odontogenic maxillary sinusitis (OMS), providing evidence for infection origin tracing and precise antimicrobial therapy in OMS. Methods: This study was reviewed and approved by the institutional ethics committee. Nine consecutive OMS patients who underwent synchronous endoscopic sinus surgery and tooth extraction from October 2020 to August 2022 were prospectively enrolled. Under general anesthesia, paired specimens were collected from infected extraction-socket granulation tissue and maxillary sinus pus. Bacterial DNA was extracted, and the full-length 16S rRNA gene was sequenced on the Illumina MiSeq platform. Amplicon sequence variants (ASVs) were generated using the DADA2 algorithm and taxonomically annotated to the subspecies level against the Human Oral Microbiome Database. The detection rate of shared ASVs between the two sites and their relative abundance in sinus pus were compared. Functional profiles were predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2 (PICRUSt2). Results: Shared ASVs were identified in seven of the nine patients. Fusobacterium, Parvimonas, Porphyromonas, and Prevotella were the most prevalent genera. Porphyromonas gingivalis and Fusobacterium nucleatum were co-detected in multiple patients, with relative abundances exceeding 5% in sinus pus of several cases. Identical ASVs of F. nucleatum or Porphyromonas spp. were detected in six patients; the ASVs corresponding to F. nucleatum subsp. nucleatum and Porphyromonas endodontalis were significantly more abundant in sinus pus than in extraction-socket granulation tissue. PICRUSt2 functional profiling revealed that the proportion of socket-derived microbes in sinus pus was strongly correlated with 10 pathways, including ferroptosis, adipocytokine signaling, and apoptosis, et al. Except for biotin metabolism, the remaining pathways showed weak correlation with the proportion of extraction socket-derived ASVs in the extraction-socket granulation tissue and maxillary sinus pus. Removing F. nucleatum ASVs markedly attenuated these associations Conclusion At the subspecies-strain level, this study confirmed the presence of a shared microbial profile between infected extraction-socket granulation tissue and maxillary sinus pus in patients with odontogenic maxillary sinusitis. The co-detected subspecies-strains with high relative abundance in maxillary sinus pus included Fusobacterium nucleatum subsp. nucleatum and Porphyromonas endodontalis, thus providing strain-level microbiological evidence for infection source tracing in OMS.

This study aims to investigate the action mechanism of Shenzhuo Decoction(SZT, i.e., Ganjiang Lingzhu Decoction) in treating knee osteoarthritis(KOA). Network pharmacology was used to analyze the key targets of SZT in the treatment of KOA. At the cellular experimental level, primary chondrocytes extracted from rats were used for in vitro validation. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL) staining was employed to detect chondrocyte apoptosis in the knee joint. Western blot was performed to analyze the expression of the anti-apoptotic factor(Bcl2), the apoptosis marker gene Bax, and key proteins in the phosphoinositide 3-kinase(PI3K)-protein kinase B(Akt) signaling pathway. In animal experiments, 60 7-week-old male SD rats were used to establish a KOA model and randomly divided into a control group, a KOA model group, high-, medium-, and low-dose SZT groups, and a celecoxib group, with 10 rats in each group. Micro-CT was used to observe changes in bone mineral density and osteophytes at the articular cartilage surface. Hematoxylin-eosin(HE) staining and safranin O-fast green(SFO) staining were used to observe pathological changes in cartilage tissue. Immunohistochemistry was used to detect the expression of inflammatory factor matrix metalloproteinase 13(MMP13) and cartilage marker collagen Ⅱ. Quantitative reverse transcription-polymerase chain reaction(qRT-PCR) was used to detect the expression of chondrocyte marker SRY-box transcription factor 9(SOX9) and inflammatory markers matrix metalloproteinase 9(MMP9), interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α). Cell experiments revealed that SZT effectively improved KOA, and the results of micro-CT and HE and SFO staining showed that compared with the control group, the model group had obvious formation of osteophytes on the joint surface, which became rough, with significant decreases in the trabecular bone volume fraction(BV/TV), trabecular number(Tb.N), and trabecular thickness(Tb.Th) and a significant increase in trabecular spacing(Tb.Sp). The SZT groups had few osteophytes and a smoother joint surface than the model group. Additionally, BV/TV, Tb.N, and Tb.Th were significantly increased, while Tb.Sp was gradually decreased. A SZT-component-KOA target network was constructed to locate the core targets in KOA treatment, which was further validated through in vivo and in vitro animal experiments. The immunohistochemistry results of the pathological section of rat joint tissue showed that compared with the control group, the model group had a significant increase in MMP13 and a decrease in collagen Ⅱ, while SZT could inhibit inflammation and strengthen the protection of collagen Ⅱ in articular cartilage. The qRT-PCR results showed that SZT could significantly inhibit the mRNA expression of IL-6, IL-1β, TNF-α, and MMP9 and upregulate the mRNA level of SOX9. The TUNEL detection results showed that in the lipopolysaccharide(LPS)-induced KOA model group, chondrocyte apoptosis was significantly increased, and the fluorescence intensity was significantly enhanced. SZT, however, significantly reduced the trend of chondrocyte apoptosis and decreased the fluorescence intensity. The Western blot results showed that SZT could effectively inhibit the phosphorylation level of proteins in the PI3K-Akt pathway, reduce the expression of Bax, increase the expression of Bcl2, and inhibit the degradation of SOX9. In conclusion, SZT may alleviate the degenerative damage of KOA by inhibiting the phosphorylated expression of key proteins in the PI3K-Akt signaling pathway, reducing the release of inflammatory factors, and inhibiting chondrocyte apoptosis.

The efficacy mechanism of the alcoholic extract of Gnaphalium affine was investigated by observing its influence on oxidative stress and intestinal flora in rats modeled for chronic obstructive pulmonary disease(COPD). UPLC-MS was used to evaluate the quality of the alcoholic extract of G. affine, and 72 rats were randomly divided into six groups, with COPD models established in five groups by cigarette smoke combined with airway drip lipopolysaccharide, and the rats were given the positive drug of Danlong Oral Solution, as well as low-, medium-, and high-doses alcoholic extract of G. affine, respectively. After two weeks of continuous gastric gavage, the body weights and general morphology observations were performed; HE staining and Masson staining were used to verify the effects of the alcoholic extract of G. affine on alveolar inflammation and collagen deposition area in COPD rats; the oxidative stress indexes CAT and GSH in serum and SOD and MDA in lung tissue of the rats were measured, and the mRNA expression of HO-1, Nrf2, and NQO1 were determined by qRT-PCR. The protein expressions of HO-1, Nrf2, and NQO1 were determined by the Western blot method, and the mechanism by which the alcoholic extract of G. affine affected oxidative stress in COPD rats was explored. Finally, the influence of G. affine on the changes in intestinal flora caused by COPD was studied by 16S rRNA sequencing. The results showed that a total of 121 chemical components were identified by UPLC-MS, including 70 positive and 51 negative ion modes. In animal experiments, it was found that the alcoholic extracts of G. affine were able to reduce the percentage of collagen deposition, affect the oxidative stress indexes such as CAT, GSH, SOD, MDA, as well as the mRNA and protein expression of Nrf2, HO-1, and NQO1. The 16S rRNA sequencing results showed an increase in the level of Lactobacillales and a decrease in the level of Desulfovibrio and Desulfovibrionales, suggesting that the alcoholic extracts of G. affine could reverse the changes in intestinal flora caused by COPD. In conclusion, the alcoholic extracts of G. affine may exert anti-COPD effects by affecting the oxidative stress pathway and modulating the changes in intestinal flora.

Osteoporotic fractures(OPF) refer to the fractures caused by minor violence in the state of osteoporosis, seriously threatening the life and health of elderly patients. Drug and surgical therapies have limitations such as single targets, diverse adverse reactions, and poor prognosis. Kidney-tonifying traditional Chinese medicine(TCM) has good potential in the treatment of OPF. TCM can promote the healing of OPF by promoting angiogenesis in the early stage of bone healing, promoting osteogenic differentiation of bone marrow mesenchymal stem cells in the stage of bone repair, maintaining the balance of osteogenic and osteoclastic system in the stage of bone remodeling, and regulating the oxidative stress responses throughout the process of OPF healing. TCM can alleviate the pathological state of osteoporosis and promote fracture healing in OPF patients via multiple pathways and targets, demonstrating the advantages and potential of biphasic regulation.

OBJECTIVE: To explore the efficacy of predictive nursing on the recovery of patients after endoscopic surgery for prostate under the concept of enhanced recovery after surgery（ERAS）. METHODS A total of 82 patients with benign prostatic hyperplasia who underwent surgery from February 2022 to February 2023 were divided into control group (n=41) with traditional care and the observation group (n=41) with predictive care based on the difference in nursing methods. And the clinical data of the two groups were compared. Results： The observation group showed lower incidence rates than the control group for all individual complications (urinary tract infection ［2.44% vs 4.88%］, hemorrhage ［2.44% vs 7.32%］, bladder spasm ［0% vs 4.88%］, and hypostatic pneumonia ［0% vs 2.44%］), though none reached statistical significance (P>0.05). However, the total complication rate was significantly lower in the observation group (4.88% vs 19.51%, P < 0.05). Notably，the observation group demonstrated significantly lower IPSS scores (5.49±1.53 vs 10.35±1.77, P<0.05) and shorter hospital stays (［5.26±0.38］ d vs ［9.95±0.84］ d, P<0.05). Additionally, nursing satisfaction was markedly higher in the observation group (92.68% vs 78.95%, P<0.05).Conclusion： The application of ERAS -guided anticipatory nursing in postoperative rehabilitation for patients with benign prostatic hyperplasia can significantly improve quality of life, reduce complication rates, shorten hospital stays, and enhance patient satisfaction.
