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.

Objective:To construct a quality indicator system for pain nursing process in adult inpatients and to provide a scientific, objective and practical basis for the evaluation and management of pain nursing quality in clinical nursing.Methods:Based on the guidance framework of nursing procedures, a quality index system for pain nursing process in adult inpatients was preliminarily developed. Two rounds of expert questionnaires were conducted using the Delphi method, the analytic hierarchy process was used to analyze the weight of the indicators, and the semantic analysis of the indicator system was carried out with the nurses, and finally the quality indicator system for the pain nursing process in adult inpatients was constructed.Results:Both Delphi rounds attained 100% response rates, and the expert authority coefficients were 0.96 and 0.98 respectively, the familiarity coefficients were 0.95 and 0.98 respectively, both judgment basis coefficients were 0.98, and the Kendall′s coefficient of concordance were 0.187 and 0.451 respectively.

Objective: To explore the role and molecular mechanism of parthenolide(PTL) in regulating tumor-associated macrophage(TAM) polarization to inhibit the malignant progression of gallbladder cancer cells. Methods: M0 macrophages were co-cultured with human gallbladder cancer cell line GBC-SD and treated with PTL, and the cells were divided into control group, TAM group, TAM+PTL group. Flow cytometry was used to determine the levels of CD86 and CD206 in macrophages. RT-qPCR and Western blot were used to determine the expressions of CD163, interleukin-10(IL-10) and arginase-1(Arg-1). ELISA and Western blot were used to determine the secretion of CC chemokine ligand 2(CCL2) in the supernatant of GBC-SD cells and the expression of CCL2 in the cells. GBC-SD cells were transfected with a CCL2 overexpression vector and divided into TAM, TAM+PTL, TAM+PTL+OE-NC, TAM+PTL+OE-CCL2 groups. Flow cytometry was used to assess CD86 and CD206 levels in macrophages, RT-qPCR and Western blot were used to assess CD163, IL-10 and Arg-1 expression. CCK-8 assay, plate-based colony formation assay and Transwell chamber assay were used to assess GBC-SD cell proliferation, migration and invasion, respectively. Results: Compared with the TAM group, the TAM+PTL group showed increased CD86 expression and decreased CD206 expression in macrophages, the mRNA and protein expressions of CD163, IL-10 and Arg-1 were downregulated, the CCL2 content and protein expression in GBC-SD cells decreased, cell proliferation activity, colony formation, migration and invasion were all reduced (P < 0. 05) . Compared with the TAM + PTL group , the TAM + PTL + OE-CCL2 group showed decreased CD86 expression and increased CD206 expression in macrophages , the mRNA and protein expressions of CD163 , IL-10 and Arg-1 were upregulated. Cell proliferation activity was enhanced , and colony formation , migration , and invasion all increased (P < 0. 05) . Conclusion Parthenolide inhibits the polarization of macrophages in TAM to M2 type by downregulating CCL2 expression in gallbladder cancer cells , thereby preventing the proliferation , migration and invasion of gallbladder cancer cells.

Complement C3 plays a critical role in periodontitis. However, its source, role and underlying mechanisms remain unclear. In our study, by analyzing single-cell sequencing data from mouse model of periodontitis, we identified that C3 is primarily derived from periodontal fibroblasts. Subsequently, we demonstrated that C3a has a detrimental effect in ligature-induced periodontitis. C3ar^-/- mice exhibited significantly less destruction of periodontal support tissues compared to wild-type mice, characterized by mild gingival tissue damage and reduced alveolar bone loss. This reduction was associated with decreased production of pro-inflammatory mediators and reduced osteoclast infiltration in the periodontal tissues. Mechanistic studies suggested that C3a could promote macrophage polarization and osteoclast differentiation. Finally, by analyzing single-cell sequencing data from the periodontal tissues of patients with periodontitis, we found that the results observed in mice were consistent with human data. Therefore, our findings clearly demonstrate the destructive role of fibroblast-derived C3 in ligature-induced periodontitis, driven by macrophage M1 polarization and osteoclast differentiation. These data strongly support the feasibility of C3a-targeted interventions for the treatment of human periodontitis.

OBJECTIVES: This study aims to analyze the clinical symptoms and imaging manifestations in patients with temporomandibular disorder syndrome (TMD), who are sensitive to sudden temperature drop. METHODS: One hundred and nineteen patients with TMD who attended the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital from December 2022 to December 2023 were included, including 44 males and 75 females, with a mean age of 32.4±13.7 years.The questionnaire was used to determine whether they were sensitive to temperature drop, and the TMD patients were divided into a temperature plunge-sensitive group and a temperature drop insensitive group. The clinical symptoms and imaging manifestations of patients in the two groups were observed. SPSS 25.0 was used for statistical analysis. RESULTS: There was no statistically significant difference between the gender and age of patients in the temperature plunge-sensitive group (50 patients) and the insensitivity group (69 patients) (P>0.05). The percentage of patients with pain was slightly higher in the temperature plunge-sensitive group [86.0% (43/50)] than in the insensitive group [68.1% (47/69)], and the difference was statistically significant (χ²=5.031, P=0.025), while the differences in joint murmur and mouth opening limitation between the two groups were not statistically significant. A total of 238 lateral joints were detected in both groups, the percentage of osteoarthropathic imaging changes was significantly higher in the temperature plunge-sensitive group [82.0% (82/100)] than in the insensitive group [53.6% (74/138)] (χ²=20.675, P<0.001). Magnetic imaging showed that the percentage of joint effusion was higher in patients in the temperature plunge-sensitive group [66.0% (33/50)] than in the insensitive group [42.0% (29/69)], and the difference was statistically significant (χ²=5.602, P=0.018). CONCLUSIONS TMD patients with maxillofacial pain symptoms, joint effusions, and abnormal imaging of osteoarticular structures are more likely to be sensitive to sudden temperature drops.

OBJECTIVES: This study aimed to investigate the correlation between clinical symptoms and unilateral chewing habits in patients with temporomandibular disorder (TMD) accompanied by tinnitus. METHODS: A total of 285 patients diagnosed with TMD at the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital between December 2020 and May 2024 were included and divided into two groups: tinnitus group and non-tinnitus group. Analysis was conducted on the proportion of patients with unilateral chewing habits in both groups, the correlation between the side of tinnitus and the side of unilateral chewing, and the correlation of tinnitus with TMD clinical symptoms (joint clicking, joint pain, and limited mouth opening) and unilateral chewing habits. The correlation of the type of disc displacement with unilateral chewing and tinnitus was also examined. RESULTS: In the tinnitus group, the proportions of patients with and without unilateral chewing habits were 90.70% (39/43) and 9.30% (4/43), respectively. In the non-tinnitus group, the proportions of patients with and without unilateral chewing habits were 76.03% (184/242) and 23.97% (58/242), respectively. The proportion of patients with unilateral chewing habits in the tinnitus group was significantly higher than in the non-tinnitus group (χ²=4.613, P<0.05). Correlation analysis showed a positive correlation between tinnitus and unilateral chewing habits (P<0.05). In the left-sided tinnitus group, the proportion of left-sided unilateral chewers [54.55% (12/22)] was higher than that of right-sided unilateral chewers [45.45% (10/22)]. In the right-sided tinnitus group, the proportion of right-sided unilateral chewers [81.82% (9/11)] was higher than that of left-sided unilateral chewers [18.18% (2/11)]. The difference was statistically significant (χ²=7.282, P<0.05). A positive correlation was also found between the side of tinnitus and the side of unilateral chewing habits (P<0.05). The proportion of patients with pain was significantly higher in the tinnitus group than in the non-tinnitus group (P<0.05). No significant difference in the proportion of joint clicking or limited mouth opening and disc displacement (no disc displacement, unilateral disc displacement, bilateral disc displacement, reducible disc displacement, or irreducible disc displacement) was found between the tinnitus and non-tinnitus groups (P>0.05). CONCLUSIONS TMD with unilateral chewing habits may be a contributing factor to unexplained tinnitus. Unexplained tinnitus is correlated with joint pain in patients with TMD.

Bladder cancer is one of the most common malignancy in the urinary system over the world. Urine cytology and cystoscopy are important tools for bladder cancer diagnosis and recurrence monitoring. However, due to the limited sensitivity and invasive procedure, there is an urgent need to develop new non-invasive and highly sensitive liquid biopsy approaches. Urine biopsy is a research focus in the field and has great potential. This review focused on protein-based urine markers (including NMP22, BTA and UroVysion etc.) and DNA or RNA-based urine markers (including cfDNA, AssureMDx and Xpert BC Monitor etc.), which were used for bladder cancer diagnosis and recurrence monitoring, and summarized the sensitivity and specificity of each biomarker as well as their characteristics in the diagnosis and recurrence surveillance of bladder cancer. This study provides theoretical and empirical support for further optimization and application of these biomarkers in clinical practice.

Background::Clinical opportunistic screening is a cost-effective cancer screening modality. This study aimed to establish an easy-to-use diagnostic model serving as a risk stratification tool for identification of individuals with malignant gastric lesions for opportunistic screening.Methods::We developed a questionnaire-based diagnostic model using a joint dataset including two clinical cohorts from northern and southern China. The cohorts consisted of 17,360 outpatients who had undergone upper gastrointestinal endoscopic examination in endoscopic clinics. The final model was derived based on unconditional logistic regression, and predictors were selected according to the Akaike information criterion. External validation was carried out with 32,614 participants from a community-based randomized controlled trial.Results::This questionnaire-based diagnostic model for malignant gastric lesions had eight predictors, including advanced age, male gender, family history of gastric cancer, low body mass index, unexplained weight loss, consumption of leftover food, consumption of preserved food, and epigastric pain. This model showed high discriminative power in the development set with an area under the receiver operating characteristic curve (AUC) of 0.791 (95% confidence interval [CI]: 0.750–0.831). External validation of the model in the general population generated an AUC of 0.696 (95% CI: 0.570–0.822). This model showed an ideal ability for enriching prevalent malignant gastric lesions when applied to various scenarios.Conclusion::This easy-to-use questionnaire-based model for diagnosis of prevalent malignant gastric lesions may serve as an effective prescreening tool in clinical opportunistic screening for gastric cancer.
