AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To analyze the clinical characteristics of eosinophilic lung diseases(ELD) in children to enhance pediatricians′ understanding of ELD.Methods:In this retrospective cross-sectional study, a total of 149 children with ELD were recruited from Beijing Children′s Hospital, Capital Medical University between April 1, 2007 and March 31, 2022.Chi-square test, Fisher′s exact test, Mann-Whitney U test and Kruskal-Wallis test were used to analyze data and conclude clinical characteristics.Spearman correlation was used to analyze the correlation between eosinophils in peripheral blood and bronchoalveolar lavage fluid.Chi-square test and Kappa consistency test were used to compare the differences and consistency in diagnostic results between bronchoalveolar lavage fluid or lung biopsy and eosinophil elevation with chest imaging abnormalities. Results:(1)The isolated lung involvement was mostly caused by allergic bronchopulmonary aspergillosis(9 patients), and other system involvement by idiopathic hypereosinophilic syndrome(89 patients).(2)The main respiratory manifestations included coughing(90 cases, 60.4%) and expectoration(41 cases, 27.5%), while 23.5%(35 cases) of patients had no respiratory symptoms; 50.3% had digestive system involvement, and 40.9% had skin involvement.These were the two most commonly affected organs.(3)Spearman correlation was performed between eosinophils in peripheral blood and bronchoalveolar lavage fluid( r=0.3, P<0.05).Chi-square test was performed to compare ELD diagnosed by bronchoalveolar lavage fluid or lung biopsy with peripheral blood eosinophilia accompanied by abnormal chest imaging( P<0.05).Kappa consistency test(Kappa<0.2) showed poor consistency between the two diagnostic methods. Conclusions:ELD are present in children, and multiple etiologies may be pathogenic.Among children with ELD, the isolated lung involvement is mainly caused by allergic bronchopulmonary aspergillosis.The digestive system and skin are the most commonly affected organs, except for lungs.The correlation between eosinophil levels in peripheral blood and bronchoalveolar lavage fluid is poor.

Objective:To explore the composition and trajectory of symptom clusters during perioperative period in middle-aged and elderly patients with gynecological malignant tumors, so as to provide reference for formulating symptom management programs.Methods:From December 2022 to September 2023, convenience sampling was used to select 145 middle-aged and elderly patients with gynecological malignant tumors who underwent surgical treatment at the Affiliated Cancer Hospital of Xinjiang Medical University as the study subject. A longitudinal survey was conducted on patients at four time points [1 day before surgery (T1), 1 day after surgery (T2), 3 days after surgery (T3), and 7 days after surgery (T4, before discharge) ] using the General Information Questionnaire and the Chinese version of the Anderson Symptom Inventory-Perioperative Module in Patients with Gynecological Cancer.Results:A total of 145 questionnaires were distributed, and 130 valid questionnaires were collected, with an effective response rate of 89.66% (130/145). Exploratory factor analysis extracted six symptom clusters, namely perimenopausal symptom cluster, psychological symptom cluster, fatigue-pain symptom cluster, gastrointestinal symptom cluster, energy deficiency symptom cluster, and surgery related symptom cluster. Perimenopausal symptom group was a specific symptom cluster of gynecological malignant tumor patients, existing at T1. Psychological symptom cluster persisted during the patient's perioperative period. Fatigue-pain symptom cluster and surgery related symptom cluster existed at T2 to T4. Gastrointestinal symptom cluster and energy deficiency symptom cluster existed at T2 and T3.Conclusions:Middle aged and elderly patients with gynecological malignant tumors have various symptoms during the perioperative period, and the symptoms can cluster at different time points. The number of symptom clusters increases with the progress of surgical treatment, while the core symptoms within the cluster remain relatively stable over time. Clinical nursing staff should pay attention to the dynamic changes in the patient's perioperative symptom cluster, adopt efficient and targeted management measures based on the trajectory of symptom clusters, and reduce the burden of perioperative symptoms on patients.

To improve the understanding of clinicians on the diagnostic criteria and treatment principlis of pulmonary alveolar proteinosis(PAP),which is a rare respiratory disease.European Respiratory Society published the first edition guidelines for PAP,including a systematic review of the literature and the application of the grading of recommendations,assessment,development and evaluation(GRADE)approach to assess the certainty of evidence and the strength of recommendations.Five questions of patient,intervention,comparison,outcome(PICO)and two narrative questions were developed.Recommendations and evidence-based evidence were given,including management of PAP,whole lung lavage,granulocyte-macrophage colony-stimulating factor(GM-CSF)therapy,rituximab,plasma exchange,and lung transplantation.In addition,recommendations were given for the use of GM-CSF antibody testing,bronchoalveolar lavage,and lung biopsy.This study is to interpret the main content of the guideline.

Ameloblastoma is a benign tumor characterized by locally invasive phenotypes,leading to facial bone destruction and a high recurrence rate.However,the mechanisms governing tumor initiation and recurrence are poorly understood.Here,we uncovered cellular landscapes and mechanisms that underlie tumor recurrence in ameloblastoma at single-cell resolution.Our results revealed that ameloblastoma exhibits five tumor subpopulations varying with respect to immune response(IR),bone remodeling(BR),tooth development(TD),epithelial development(ED),and cell cycle(CC)signatures.Of note,we found that CC ameloblastoma cells were endowed with stemness and contributed to tumor recurrence,which was dominated by the EZH2-mediated program.Targeting EZH2 effectively eliminated CC ameloblastoma cells and inhibited tumor growth in ameloblastoma patient-derived organoids.These data described the tumor subpopulation and clarified the identity,function,and regulatory mechanism of CC ameloblastoma cells,providing a potential therapeutic target for ameloblastoma.

Objective:To explore the relationship between perceived stigma and self-transcendence meaning of life among male college students who have sex with men with HIV,and the role of fear of negation evaluation,seeking for meaning,perspective change in it.Methods:A total of 474 male college students who had sex with men with HIV were selected and tested with the simplified Berger HIV Stigma Scale(BHSS),Fear of Negative Evalua-tion Rating Scale(FNE),Chinese Meaning in Life Questionnaire(C-MLQ),Meaning-focused Coping Questionnaire(MFCQ),and Self-transcendence Meaning of Life Scale(SMLS).Results:The BHSS total scores were negatively correlated with the SMLS total scores(r=0.69,P＜0.001).The FNE scores and the seeking for meaning scores were mediating variables between the BHSS total scores and the SMLS total scores,with estimated effects of-0.13 and-0.11,respectively.The FNE score and seeking for meaning score played a chain mediating role in the total scores of BHSS and SMLS,with estimated effects of-0.16,the perspective change score played a moderating role in the score of the seeking for meaning and the SMLS total score(β=0.07,P＜0.05).Conclusion:Fear of negation evaluation and seeking for meaning play a mediating role between perceived stigma and self-transcendence meaning of life,as well as the moderating effect of perspective change between the search for meaning and self-transcendence meaning of life.

Ferroptosis is a newly discovered method of programmed cell death. Current studies have shown that activation of ferroptosis-related pathways can inhibit the growth and proliferation of tumor cells and reverse their drug resistance. Oral cancer is a common malignant tumor with a high recurrence rate and high drug resistance. Inducing ferroptosis is a potential treatment strategy. There are still many uncertainties in the application of ferroptosis in the treatment of oral cancer, which need to be further explored. This article systematically introduces the mechanism of ferroptosis and its recent progress in oral cancer treatment to provide new mechanisms and methods for the clinical treatment of oral cancer. Current research shows that the mechanism of ferroptosis is mainly related to amino acid metabolism, Fe2+ metabolism, and lipid metabolism. Ferroptosis in oral cancer cells can reverse drug resistance in cancer cells and improve the activity of immune cells. New drugs, such as curcumin analogs and triptolide, can induce ferroptosis in oral cancer, and the development of nanomaterials has improved the utilization rate of drugs. Inhibiting the expression of the ferroptosis-related factors SLC7A11, NF-E2-related factor 2 (Nrf2), and ferritin heavy chain 1 (FTH1) can promote ferroptosis in oral cancer cells. It is a potential target for the clinical treatment of oral cancer, but its translation into clinical practice still needs further research.

Objective:To analyze the clinical characteristics, treatment course and prognosis of children with intermediate-high risk pulmonary embolism.Methods:The clinical data of 48 children with pulmonary embolism treated in Beijing Children′s Hospital, Capital Medical University from January 2017 to December 2021 were analyzed retrospectively.Including 12 intermediate-high risk cases and 36 low-risk cases.The clinical manifestations, laboratory results, treatment and prognosis were compared between groups by the t-test, rank sum test and Chi- square test with the yates continuity correlation or Fisher′ s exact test. Results:There were no significant differences in the sex and age between the intermediate-high risk group and the low-risk group.The proportions of patients with shortness of breath, dyspnea, cyanosis or hypoxemia were higher in the intermediate-high risk group than those of in low-risk group.Twelve children in the low-risk group did not have specific symptoms of pulmonary embolism.There were no significant differences in the D-dimer level, and the distribution of pulmonary embolism between the two groups (all P>0.05). However, the proportion of children with other thromboembolism in the intermediate-high risk group was significantly higher than that of the low-risk group, among which heart thrombosis was the most common (7 cases). There were no significant differences in the underlying diseases and thrombophilia between the two groups (all P>0.05). The treatment of the intermediate-high risk group was more active: 6/12(50.00%) patients in the intermediate-high risk group received reperfusion treatment, including 3 cases of systemic thrombolysis, 1 case of catheter thrombolysis, and 2 cases of thrombectomy.In the low-risk group, only 1 case was treated with systematic thrombolysis.Unfavorable outcomes were reported in 3/48 (6.25%) patients, including 1 death of massive bleeding after catheter-directed thrombolysis in the acute phase, 1 case of recurrent pulmonary embolism after self-decided withdrawal and 1 case of progression of pulmonary embolism that was managed by surgical thrombectomy, all of whom were in the intermediate-high risk group. Conclusions:Shortness of breath, dyspnea, cyanosis or hypoxemia and co-existed venous thromboembolism were more common in intermediate-high risk cases.The treatment regimen of was more aggressive, but the incidence of unfavorable outcomes was higher in intermediate-high risk group; further research is needed to determine the risk factors for intermediate-high risk pulmonary embolism in children.
