OBJECTIVES: To explore the association between Chinese visceral adiposity index (CVAI) and the risk of nephrolithiasis. METHODS: This cross-sectional study analyzed data from 78 438 Chinese adults who underwent ultrasound examinations during health screening at the Health Examination Center of Affiliated Hospital of Yangzhou University. Participants were divided into quartiles (Q1-Q4 groups) based on CVAI. Multivariate logistic regression models were utilized to evaluate the association between CVAI and nephrolithiasis risk, followed by subgroup analyses to further explore potential relationships. The performance of CVAI in predicting the risk of nephrolithiasis was evaluated using receiver operating characteristic (ROC) curves. RESULTS: Increased CVAI was significantly associated with a higher risk of nephrolithiasis, with prevalence rising from 3.36% in the Q1 group to 10.67% in the Q4 group (P<0.01). In adjusted models, CVAI was positively correlated with the prevalence rate of nephrolithiasis (OR=1.002, 95%CI: 1.001-1.004, P<0.01). The risks of nephrolithiasis in the Q2, Q3, and Q4 groups were 1.196-fold (95%CI: 1.069-1.338, P<0.01), 1.260-fold (95%CI: 1.109-1.433, P<0.01), and 1.316-fold (95%CI: 1.125-1.539, P<0.01) higher than in the Q1 group, respectively. Subgroup analysis revealed that CVAI was positively associated with the risk of nephrolithiasis in male participants, individuals aged <60 years, the hypertension group, populations with or without diabetes mellitus, and the normal body mass index subgroup. Genders and age had an interaction effect on the correlation between CVAI and the risk of nephrolithiasis development (both P<0.05). The ROC curve analysis demonstrated that CVAI exhibited superior predictive efficacy compared to waist circumference, body mass index, visceral adiposity index, weight-adjusted waist index, cardiometabolic index and body shape index, with an area under the curve of 0.622. CONCLUSIONS In Chinese adults, CVAI is positively associated with the risk of nephrolithiasis development, which may serve as a potential predictive marker for nephrolithiasis.

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.

Objective This study aims to observe the clinical effect of bone plate reduction in combination with a re-sorbable plate on large mandibular cysts.Methods Between October 2017 and September 2022,patients with large mandibular cysts in the presence of labial and buccal cortical bone were involved in the study.Intraoral approach was performed for bone plate reduction.Cone beam computed tomography(CBCT)scan was reviewed at 3,6,and 9 months postoperatively to observe postoperative complications.Osteogenic results were assessed at these times to determine the clinical outcomes of this procedure.Results Eleven cases with large mandibular cysts in the presence of cortical bone were evaluated.The average thickness of the cortical bone on the labial and buccal sides was measured to be about(1.98±0.37)mm before surgery,with a mean value of(0.73±0.17)mm at the thinnest part of the plate and up to 0.51 mm at the thinnest part of the plate.The cystic cavities were well re-vealed during the surgeries,which were completed suc-cessfully.Postoperatively,the wounds healed in one stage without infection.The percentages of cyst shrinkage were 20.01%,41.76%,and 73.41%at 3,6,and 9 months after surgery,respectively.Quantitative measurement of bone mineral density in the jaws by CBCT with MIMICS software.The bone mineral densities of the adult bone were 313.78,555.85,and 657.45 HU at the 3,6,and 9 month time intervals,respectively.No significant change in the patient's maxillofacial appearance were observed from the preoperative period as assessed by the patient's and observer's visual analog scale.Conclusion Bone plate reduction is an effective treatment for large mandibular cysts of the oral and maxillofacial re-gion with the presence of cortical bone.

Objective:To analyze the association between the triglyceride-glucose(TyG)index and the risk of nephrolithiasis across various demographic and clinical subgroups,aiming to enhance early di-agnosis and treatment of nephrolithiasis and promote personalized care in diverse populations.Methods:This cross-sectional study analyzed the medical records of 84 968 adults,stratified into three categories(low,middle,high)according to their TyG index scores.To evaluate the association between the TyG index and nephrolithiasis risk,multivariable Logistic regression models were employed,adjusting for po-tential confounders.Additionally,piecewise linear regression models were used to investigate the non-linear dynamics of the TyG index's relationship with nephrolithiasis risk.Subgroup analyses were per-formed to explore variations in the effects of the TyG index across different demographic and clinical populations.Results:Increasing TyG index was associated with a higher risk of nephrolithiasis,rising from 4.36％in the low group to 8.96％in the high group(P＜0.001).In adjusted models,males in the middle and high TyG index categories demonstrated significantly elevated risks of nephrolithiasis,with odds ratios of 1.18(95％CI:1.07-1.31,P=0.002)and 1.29(95％CI:1.15-1.45,P＜0.001),respectively.Conversely,in females,the association was not statistically significant post-adjustment(OR=0.98,95％CI:0.82-1.16,P=0.778).Among males,for each unit increment in the TyG index be-low the critical threshold of 8.98,there was a notable 40％escalation in the risk of developing nephroli-thiasis(OR=1.40,95％CI:1.24-1.58,P＜0.001).Surpassing this threshold,the TyG index no longer conferred a significant increase in risk(OR=0.91,95％CI:0.78-1.06,P=0.24).Subgroup analyses indicated that this association remained stable regardless of age,BMI,or hypertension status.Conclusion:The TyG index is positively associated with the risk of nephrolithiasis in males,demonstra-ting a nonlinear dose-response relationship that becomes especially pronounced at certain index levels.This biomarker could potentially serve as a valuable clinical tool for identifying males who are at a high risk of developing nephrolithiasis,thereby enabling targeted preventive strategies.Further research is urgently needed to explore the underlying mechanisms and to verify the applicability of these results across different populations.

Objective:To screen key genes that co-regulate immune and mitochondrial energy metabolism through bioinformatics methods and to investigate the relationship between the key genes and immune infiltration.Methods:A total of 671 glioma samples (the tumor group) and 5 non-tumor brain tissue samples (the control group) were collected from the Cancer Genome Atlas (TCGA) database on November 13, 2023. Through a comprehensive search of the GeneCards database and immune-related genes (IRG) and mitochondrial energy metabolism-related genes (MEMRG) in previous published literatures, 76 IRG and MEMRG (IR & MEMRG) were obtained by taking the intersection of IRG and MEMRG after merging and deduplicating. The limma package in R software was used to screen the differentially expressed genes (DEG) between the tumor group and the control group. Then, immune-related & mitochondrial energy metabolism-related differentially expressed genes (IR&MEMRDEG) were obtained by intersecting with IR & MEMRG. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted on the IR&MEMRDEG through the clusterProfiler package in R software. The STRINGv12.0 online database (https://cn.string-db.org/) was employed to construct a protein interaction network based on IR&MEMRDEG and to identify the top 5 key core genes. Single-sample gene-set enrichment analysis (ssGSEA) was used to determine the relative abundance of immune cell infiltration in all samples, and the immune cell infiltration matrices for both the tumor and the control groups were acquired. The expression differences in infiltration abundance of the immune cells in the tumor group and the control group were analyzing by using the ggplot2 package in R software. The heat map was drawn by utilizing the R software pheatmap package to show self-correlation of immune cells. The correlation between the top 5 key genes in the protein interaction network and immune cells was calculated by using the Spearman algorithm and the R software ggplot2 package.Results:A total of 3 623 DEGs were identified from the TCGA database in both groups, including 1 711 up-regulated genes and 1 912 down-regulated genes. After taking the intersection of DEG and IR&MEMRG, 11 IR&MEMRDEG were obtained including EIF4EBP1, TP53, IDH1, PRCKZ, CD200, GPI, PGM2, PKLR, AK2, ATP4A, and ALDH3B1. GO enrichment analysis results showed that 11 IR&MEMRDEG were mainly enriched in ADP metabolic process, ATP metabolic process, purine nucleoside diphosphate metabolic process, purine ribonucleoside diphosphate metabolic process, and ribonucleoside diphosphate metabolic process at the biological level; in the fibronectin-1 rich granule, secretory granule lumen, cytoplasmic vesiclelumen, vesiclelumen, and nuclear matrix at the cellular component level; in magnesium ion binding, potassium ion binding, and alkali metal ion binding at the molecular functional level. The KEGG enrichment analysis results showed that 11 IR&MEMRDEGs were mainly enriched in glycolysis/gluconeogenesis, carbon metabolism, insulin signaling pathway, pentose phosphate pathway, starch and sucrose metabolism signaling pathways. The protein interaction network analysis from the STRING database revealed that 5 highest scoring core proteins were identified, namely EIF4EBP1, TP53, IDH1, PRKCZ, and AK2.The immune infiltration abundances of 28 immune cells were calculated by using the ssGSEA algorithm. The infiltration abundance of 15 immune cells in the tumor group was higher than that in the control group, and the differences were statistically significant (all P < 0.05). The findings from the immune infiltration analysis indicated a positive correlation among 15 types of immune cells, in which there was a strongest correlation between effector memory CD8 + T cell and myeloid derived suppressor cells. EIF4EBP1, TP53, IDH1, and AK2 exhibited a positive correlation with a large number of immune cells (all P < 0.05), whereas PRKCZ demonstrated a negative correlation with more immune cells (all P < 0.05). Conclusions:PRKCZ, AK2, and EIF4EBP1 have the potential to be the new targets of immunotherapy for gliomas.

Objective: The aim of this study was to determine the poly (ADP-ribose) polymerase inhibitors (PARPis) response and outcome of ovarian cancer (OC) patients with BRCA1/2 germline mutation and a history of breast cancer (BC). Methods: Thirty-nine OC patients with BRCA1/2 germline mutation and a history of BC were included. The clinicopathological characteristics, PARPis response and prognosis were analyzed. Results: The median interval from BC to OC diagnosis was 115.3 months (range=6.4–310.1).A total of 38 patients (38/39, 97.4%) received platinum-based chemotherapy after surgical removal. The majority of these patients were reported to be platinum sensitive (92.1%, 35/38).21 patients (53.8%) received PARPis treatment with 16 patients (76.2%) for maintenance treatment and 5 patients (5/21, 23.8%) for salvage treatment. The median duration for PARPis maintenance and salvage treatment was 14.9 months (range=2.0–56.9) and 8.2 months (range=5.2–20.7), respectively. In the entire cohort, 5-year progression-free survival (PFS) and overall survival (OS) rate was 33.1% and 78.9%, respectively. Patients with BRCA1 mutation had a non-significantly worse 5-year PFS (28.6% vs. 45.8%, p=0.346) and 5-year OS (76.9% vs.83.3%, p=0.426) than those with BRCA2 mutation. In patients with stage III–IV (n=31), first line PARPis maintenance treatment associated with a non-significantly better PFS (median PFS: NR vs. 22.4 months; 5-year PFS: 64.3% vs. 21.9%, p=0.096). Conclusion The current study shows that these patients may have a good response to platinum-based chemotherapy and a favorable survival. And these patients can benefit from PARPis treatment and will likely be suitable candidates for PARPis.

Objective    To identify the risk factors for hospital mortality in patients with acute myocardial infarction (AMI) after emergency coronary artery bypass grafting (CABG). Methods    We retrospectively analyzed the clinical data of 145 AMI patients undergoing emergency CABG surgery in Qingdao Municipal Hospital from 2009 to 2019. There were 108 (74.5%) males and 37 (25.5%) females with a mean age of 67.7±11.5 years. According to whether there was in-hospital death after surgery, the patients were divided into a survival group (132 patients) and a death group (13 patients). Preoperative and operative data were analyzed by univariate analysis, followed by multivariate logistic regression analysis, to identify the risk factors for hospital mortality. Results    Over all, 13 patients died in the hospital after operation, with a mortality rate of 9.0%. In univariate analysis, significant risk factors for hospital mortality were age≥70 years, recent myocardial infarction, left ventricular ejection fraction (LVEF)<30%, left main stenosis/dissection, operation time and simultaneous surgeries (P<0.05). Multivariate logistic regression analysis showed that LVEF<30%(OR=2.235, 95%CI 1.024-9.411, P=0.014), recent myocardial infarction (OR=4.027, 95%CI 1.934-14.268, P=0.032), operation time (OR=1.039, 95%CI 1.014-1.064, P=0.002) were independent risk factors for hospital mortality after emergency CABG. Conclusion    Emergency CABG in patients with AMI has good benefits, but patients with LVEF<30%and recent myocardial infarction have high in-hospital mortality, so the operation time should be shortened as much as possible.
