BACKGROUND:At present,the incidence of scoliosis is increasing year by year,especially in adolescent idiopathic scoliosis.Therefore,it is more and more important to strengthen the research on the treatment of adolescent scoliosis. OBJECTIVE:To summarize the current status,hotspots,emerging trends,and frontiers of global research on the treatment of adolescent idiopathic scoliosis to provide reference and guidance for future related research. METHODS:The literature related to the treatment of adolescent idiopathic scoliosis was retrieved on the Web of Science Core Collection(WOSCC)database from 2013 to 2023.CiteSpace 6.2.R1 software was used for visual analysis of countries,institutions,authors,and keywords. RESULTS AND CONCLUSION:(1)A total of 561 English articles were included in this study.Among countries,institutions,and authors,the United States has contributed the most.Nanjing University and Qiu,Yong(Affiliated Drum Tower Hospital,Nanjing University School of Medicine)are the most published institution and author.The academic journal with the largest number of articles is the European Spine Journal.(2)In the analysis of cited literature,the top 10 most cited articles mainly describe the effects of surgical treatment and conservative treatment on improving adolescent idiopathic scoliosis,especially improving the curvature of patients.(3)Through the summary of highly cited articles and the keyword clustering,keyword prominence in-depth mining,the research hotspots are currently the relationship between Cobb angle and treatment choice,the therapeutic effect of exercise therapy and the therapeutic effect of posterior vertebral fusion.(4)The prognosis of patients with different curvatures has not been studied in depth,and the etiology of adolescent idiopathic scoliosis has not been clarified,so the relationship between curvature and prognosis and the etiology of adolescent idiopathic scoliosis may be a new research trend in the future.

Occupational health technical service (OHTS) is one of the core contents in the technical support system of occupational disease prevention and control, and efficient management of OHTS institutions is necessary for improving the service ability. At present, OHTS institutions in China face several issues, such as uneven distribution in terms of quantity, function, unclear area coverage and roles and overlapping responsibilities among different types of institutions, and insufficient service capabilities with inconsistent service levels in some institutions. With the implementation of the national reform like the “separating permits from business license” and “delegate power, streamline administration and optimize government services"”policies, the management mode and operational approach of OHTS institutions have been profoundly changed. In light of this, five key recommendations are proposed to improve the management of OHTS institutions and enhance their management effectiveness, ensuring the sustainable development of national OHTS services. Firstly, it is necessary to clarify the relationship between national and provincial administrative levels in managing OHTS institutions to ensure their healthy and orderly development. Secondly, multiple measurements are taken to strengthen OHTS institutional capacity building to address regional disparities in technical capabilities and service quality. Thirdly, both technical capabilities and service quality should be focused on strengthening the supervision and management of OHTS institutions, preventing the decline of key conditions such as staffing, laboratories, equipment, and quality management after obtaining qualifications. Fourthly, “dual randomized- inspections and one open” and “internet+supervision” methods are used as basic tools for managing OHTS institutions operating across multiple provincial regions and enforcing cross-regional law. Fifthly, professional integrity of radiological health service institutions should be restored to effectively apply their technical advantages in their specialized fields.

Ankylosing spondylitis (AS) is linked to an increased prevalence of myocardial infarction (MI). However, research dedicated to elucidating the pathogenesis of AS-MI is lacking. In this study, we explored the biomarkers for enhancing the diagnostic and therapeutic efficiency of AS-MI. Datasets were obtained from the Gene Expression Omnibus database. We employed weighted gene co-expression network analysis and machine learning models to screen hub genes. A receiver operating characteristic curve and a nomogram were designed to assess diagnostic accuracy. Gene set enrichment analysis was conducted to reveal the potential function of hub genes. Immune infiltration analysis indicated the correlation between hub genes and the immune landscape. Subsequently, we performed single-cell analysis to identify the expression and subcellular localization of hub genes. We further constructed a transcription factor (TF)-microRNA (miRNA) regulatory network. Finally, drug prediction and molecular docking were performed. S100A12 and MCEMP1 were identified as hub genes, which were correlated with immune-related biological processes. They exhibited high diagnostic value and were predominantly expressed in myeloid cells. Furthermore, 24 TFs and 9 miRNA were associated with these hub genes. Enzastaurin, meglitinide, and nifedipine were predicted as potential therapeutic agents. Our study indicates that S100A12 and MCEMP1 exhibit significant potential as biomarkers and therapeutic targets for AS-MI, offering novel insights into the underlying etiology of this condition.

Objective:To explore the differences in bacterial community structure between proximal colon cancer (PC), distal colon cancer (DC), and rectal cancer (RC), and the values of featured microbiota in differentiating PC with tumor markers.Methods:This case-control study enrolled 85 newly diagnosed colorectal cancer patients, including 22 PC, 15 DC and 48 RC patients, and 8 colorectal adenoma patients from May 2019 to July 2022 at the Department of General Surgery, Anyang Oncology Hospital. 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.

Then, OUTs at a 97% similarity were included for taxonomic analyses, and the bacteria in Demodex mites belonged to 14 phyla, 20 classes, 51 orders, 72 families, and 94 genera. Proteobacteria was the dominant phylum, and Vibrio, Bradyrhizobium and Variovorax were dominant genera. A total of 56 362 valid sequences were obtained using ITS gene sequencing, and 147 OTUs were obtained, which belonged to 5 phyla, 17 classes, 34 orders, 68 families, and 93 genera and were annotated to Ascomycota, Basidiomycota and Chytridiomycota, with Ascomycota as the dominant phylum, and Alternaria alternata, Epicoccum, Penicillium, and Sarocladium as dominant genera. Conclusions There is a high diversity in the composition of bacterial communities in human Demodex mites, with multiple types of microorganisms and high species abundance.

Objective To investigate the activity of Acorus tatarinowii extracts against dust mites, and to isolate and characterize active ingredient of A. tatarinowii extracts. Methods The essential oil components were extracted from A. tatarinowii rhizome powder by rotary evaporation with methanol as solvents, followed by petroleum ether extraction and rotary evaporation. The essential oil was mixed with Tween-80 at a ratio of 1:1 and diluted into concentrations of 1.000 00%, 0.500 00%, 0.250 00%, 0.125 00%, 0.062 50% and 0.031 25%, while diluted Tween-80 served as controls. A. tatarinowii essential oil at each concentration (200 μL) was transferred evenly to filter papers containing 100 adult mites, with each test repeated in triplicate, and controls were assigned for each concentration. Following treatment at 25 °C and 75% relative humidity for 24 h, the mean corrected mortality of mites was calculated. The essential oil components were separated by silica gel column chromatography, and the essential oil was prepared in the positive column of medium pressure; and then, each component was collected. Silica gel column chromatography was run with the mobile phase that consisted of petroleum ether solution containing 10% ethyl acetate and pure ethyl acetate, detection wavelength of 254 nm, positive silica gel column as the chromatography column, and room temperature as the column temperature. Each component of the purified A. tatarinowii essential oil was diluted into 1.000 00% for acaricidal tests. The components with less than 100% acaricidal activity were discarded, and the remaining components were diluted into 50% of the previous-round tests for subsequent acaricidal tests. The components with acaricidal activity were subjected to high-performance liquid chromatography, liquid chromatography-mass spectrometry and pulsed-Fourier transform nuclear magnetic resonance spectroscopy. The structure of active monomer compounds was determined by standard spectral library retrieval and literature review. Results A. tatarinowii essential oil at concentrations of 1.000 00%, 0.500 00%, 0.250 00% and 0.125 00% killed all dust mites, and the corrected mortality was all 100%. Exposure to A. tatarinowii extracts at an effective concentration of 0.062 50% for 24 hours resulted in 94.33% mortality of dust mites. Six components (A to F) were separated using gel column chromatography, and components D and E both showed a 100% acaricidal activity against dust mites at a concentration of 0.50000%. In addition, Component D was identified as isoeugenol methyl ether, and Component E as β-asarinol. Conclusion The extract of A. tatarinowii essential oil has acaricidal activity, and the isoeugenol methyl ether shows a remarkable acaricidal activity against dust mites.

ObjectiveTo compare the air disinfection effects of different human-machine coexistence disinfection methods in the high-risk areas of airborne diseases in medical and healthcare institutions, and to provide a reference for the prevention and control of airborne diseases in medical and healthcare institutions. MethodsField trials were conducted in the fever clinic, the infection disease department, and dental clinics of a tertiary hospital in Shanghai, respectively. The existing air disinfection methods (plasma air disinfection machine, circulating air ultraviolet disinfection machine or negative pressure ventilation system), upper-room 222 nm ultraviolet germicidal system, and the combination of the existing air disinfection methods and upper-room 222 nm ultraviolet germicidal system were all used in each location in the experiment group. The control group did not adopt specific air disinfection methods. Air sampling was conducted by the six-level sieve hole microbial sampler or the flat slab exposure method. The daily air sampling time was from 8:00 a.m. to 16:00 p.m., with one sample per hour, and a total of 9 samples were taken. The disinfection effects were compared by calculating the total number of airborne bacteria colonies and the sterilization rate for each disinfection method. ResultsThe total numbers of airborne bacteria colonies in the fever outpatient infusion room, the ward and nurse station of infection disease department of 222 nm group were lower than that in the control group (P=0.005, P<0.001, P<0.001). The total numbers of airborne bacteria colonies in the fever outpatient infusion room and the dental examination room of 222 nm group were lower than that in the control group or plasma air disinfection machine group (P=0.022, P=0.014). The total numbers of airborne bacteria colonies in the nucleic acid sampling room of plasma air disinfection machine group combined with 222 nm group were lower than that in plasma air disinfection machine group (P=0.019). The total numbers of airborne bacteria colonies in the CT examination room of fever clinic of the 222 nm group were lower than that in the circulating air ultraviolet disinfection machine group (P=0.002). The total numbers of airborne bacteria colonies in the CT examination room of 222 nm group combined with circulating air ultraviolet disinfection machine were lower than that of circulating air ultraviolet disinfection machine group and the control group (P=0.008, P<0.001). The air sterilization rate of upper-room 222 nm ultraviolet germicidal system ranged from 48.04% to 73.74%. The air sterilization rate of plasma air/circulating air ultraviolet disinfection machine combined with the upper-room 222 nm ultraviolet germicidal system ranged from 6.86% to 73.77%. ConclusionUpper-room 222 nm ultraviolet germicidal system could effectively reduce airborne colonies in the air and improve air hygiene quality in both clinic and ward environments with high airborne transmission risks.

Photoreceptor cells are a special type of neuroepithelial cells, which play an important role in the generation and transmission of visual signals.They mainly meet the physiological needs by ingesting a large amount of glucose for glucose metabolism.Photoreceptor cell apoptosis is a common cause of blindness in patients with retinal diseases, which is accompanied by changes in oxidative stress and anabolism.Recent studies have found that pentose phosphate pathway, an important branch of glucose metabolism, plays an essential role in the development of the above-mentioned pathology.Its product, nicotinamide adenine dinucleotide phosphate (NADPH), as a crucial hydrogen donor in photoreceptor cells, participates in substance synthesis and metabolism, resists oxidative stress, and then inhibits apoptosis of photoreceptor cells.This review summarized the mechanism of pentose phosphate pathway in inhibiting photoreceptor cell apoptosis from the perspective of view of metabolic activity and molecular pathway to provide reference for clinical scientific research.
