Background: Gestational diabetes mellitus (GDM) is a metabolic disorder posing significant risks to maternal and infant health, with a lack of effective early screening markers. Therefore, identifying early screening biomarkers for GDM with higher sensitivity and specificity is urgently needed. Methods: High-throughput sequencing was employed to screen for key circular RNAs (circRNAs), which were then evaluated using reverse transcription quantitative polymerase chain reaction. Logistic regression analysis was conducted to examine the relationship between clinical characteristics, circRNA expression, and adverse pregnancy outcomes. The diagnostic accuracy of circRNAs for early and mid-pregnancy GDM was assessed using receiver operating characteristic curves. Pearson correlation analysis was utilized to explore the relationship between circRNA levels and oral glucose tolerance test results. A predictive model for early GDM was established using logistic regression. Results: Significant alterations in circRNA expression profiles were detected in GDM patients, with hsa_circ_0031560 and hsa_ circ_0000793 notably upregulated during the first and second trimesters. These circRNAs were associated with adverse pregnancy outcomes and effectively differentiated GDM patients, with second trimester cohorts achieving an area under the curve (AUC) of 0.836. In first trimester cohorts, these circRNAs identified potential GDM patients with AUCs of 0.832 and 0.765, respectively. The early GDM prediction model achieved an AUC of 0.904, validated in two independent cohorts. Conclusion Hsa_circ_0031560, hsa_circ_0000793, and the developed model serve as biomarkers for early prediction or midterm diagnosis of GDM, offering clinical tools for early GDM screening.

In recent years, China has been facing the dual challenges of declining fertility rates and births, with male reproductive health issues, especially the decline in semen quality, identified as a pivotal contributor to this phenomenon. Meanwhile, accumulating evidence indicates that air pollutants, an increasingly severe environmental problem, can damage semen quality not only directly through their biological toxicity but also indirectly by disrupting the composition of microbial communities in the gut and semen, thereby dysregulating immune function, endocrine homeostasis, and oxidative stress responses. The gut microbiota and semen microbiota, as important components of the human microecosystem, play crucial roles in maintaining reproductive health. This article comprehensively reviewed the research progress on the potential effects of air pollutants (particulate matter and gaseous pollutants), gut microbiota, and semen microbiota on semen quality. Specifically, it elucidated the mechanisms of interaction between these factors and explored how they affect male fertility.

Objective To investigate the association between intraoperative hypotension and post-operative acute kidney injury(AKI)in patients undergoing brain tumor resections.Methods A total of 428 patients undergoing elective craniotomy for tumor resection were selected,276 males and 152 females,aged≥18 years,BMI 15-36 kg/m2,ASA physical statusⅡ orⅢ.Based on postoperative occurrence of AKI,the patients were divided into two groups:the AKI group and the control group.This study defined three thresholds for hypotension,including MAP during surgery below 65 mmHg,60 mmHg,and 55 mmHg.Multivariate logistic regression was used to analyze the correlation between intraoperative hypotension and postoperative AKI under three thresholds.Results A total of 107 patients had postoperative AKI.The re-sults of multivariable regression analysis indicated that intraoperative MAP＜65 mmHg(OR = 1.11,95%CI 1.03-1.20,P = 0.010)and intraoperative MAP＜60 mmHg(OR = 1.12,95%CI 1.02-1.23,P = 0.017)were associated with postoperative AKI.Conclusion Intraoperative MAP＜65 mmHg or 60 mmHg is associated with postoperative AKI in patients undergoing brain tumor resection.

Objective To investigate the expression of discoidin CUB and LCCL domain containing 2(DCBLD2)and mitogen activated protein kinase kinase kinase kinase 3(MAP4K3)in thyroid cancer and their relationship with clinico-pathological features and prognosis.Methods A total of 92 patients with thyroid cancer diagnosed and treated in Xinghua People's Hospital Affiliated to Yangzhou University from January 2016 to June 2020 were selected.Immunohistochemistry(IHC)was used to detect the expression of DCBLD2 and MAP4K3 in thyroid cancer tissues and adjacent tissues.The expression differences of DCBLD2 and MAP4K3 in thyroid cancer patients with different clinicopathological features were compared.Kaplan-Meier curve analysis was used to analyze differences in the progression-free survival prognosis of patients with different DCBLD2 and MAP4K3 expressions.Multivariate COX analysis was used to analyze the risk factors affecting the progression-free survival prognosis of thyroid cancer.Results The positive rates of DCBLD2(67.39%)and MAP4K3(65.22%)in thyroid cancer tissues were higher than those in adjacent tissues(5.43%,6.52%),and the differences were statistically significant(χ2=76.262,68.894,all P<0.05).The expression of DCBLD2 was positively correlated with MAP4K3(r=0.742,P<0.001).The positive rates of DCBLD2 and MAP4K3 in stage Ⅲ～Ⅳ(87.18%,84.62%)and lymph node metastatic cancer tissues(93.75%,90.63%)were higher than those in stage Ⅰ～Ⅱ(52.83%,50.94%)and non lymph node metastatic cancer tissues(53.33%,51.67%),with statistically significant differences(χ2=11.230～15.513,all P<0.05).The 3-year progression-free survival rates of DCBLD2-positive and DCBLD2-negative patients were 74.19%(46/62)and 93.33%(28/30),respectively.The 3-year progression-free survival rates of MAP4K3 positive and negative patients were 75.00%(45/60)and 90.63%(29/32),respectively.The 3-year cumulative progression-free survival rate of DCBLD2 positive group and MAP4K3 positive group was lower than that of DCBLD2 negative group and MAP4K3 negative group,and the differences were statistically significant(χ2=4.533,4.138,P=0.033,0.046).DCBLD2 positive(OR=1.659,P=0.001),MAP4K3 positive(OR=1.606,P=0.001),tumor TNM stage Ⅲ～Ⅳ(OR=1.766,P=0.001)and combined lymph node metastasis(OR=1.868,P=0.001)were independent risk factors for the progression-free survival prognosis of thyroid cancer patients.Conclusion The expressions of DCBLD2 and MAP4K3 were increased in thyroid cancer tissue.They are involved in the occurrence and development of thyroid cancer,which may help evaluate the progression-free survival prognosis of thyroid cancer patients.

Objective To compare and analyze the application value of domestic Octoparms and imported Celect inferior vena cava filter(IVCF)in the interventional treatment of venous thromboembolism(VTE).Methods Forty patients with VTE were randomly divided into Octoparms group(experimental group)and Celect group(control group)according to the double-blinded method of the central random system.All the patients underwent filter placement,catheter-directed thrombolysis and filter retrieval.The primary end point was the success of filter placement and retrieval,and the secondary end point included indwelling complications such as the occurrence of pulmonary embolism(PE)and filter tilt and migration.Results Forty patients were enrolled in this study,22 patients and 18 patients were divided into the experimental group and the control group,respectively.Among them,11 cases were identified with right lower extremity deep vein thrombosis,29 cases with left lower extremity deep vein thrombosis,17 cases with PE,and 6 cases with inferior vena cava thrombosis.The success rate of IVCF placement was 100%in all participants.Immediately after filter place-ment,the angle of filter tilt was(3.8±2.3)° in the experimental group and(4.9±2.8)° in the control group(t=1.44,P=0.16).Filter retrieval was successful in 21 cases(21/22,95.5%)of the experimental group and 17 cases(17/18,95.5%)of the control group.There was no significant difference between the two groups(t=0.14,P=0.89).The mean indwelling time of filter was(8.0±2.1)days in the experimental group and(9.7±3.1)days in the control group(t=0.73,P=0.47).The angle of filter tilt was(5.3±3.4)° in the experimental group and(5.7±7.7)° in the control group(t=0.19,P=0.85).There was no significant difference for filter placement and retrieval between the two groups(t=0.48 and 2.00,P=0.06 and 0.64,respectively).There were no complications of filter migration,strut penetration or new PE in both groups.Conclusion The application value of domestic Octoparms and impor-ted Celect IVCF is similar in interventional treatment of VTE.

Objective:To investigate the distribution characteristics of skeletal muscle mass and strength in the older adults over 65 years old in 18 longevity areas in China.Methods:The subjects were selected from the Healthy Aging and Biomarkers Cohort Study conducted in 18 longevity areas of China. A total of 4 662 older adults over 65 years old from a cross- sectional survey in 2021 were included in the study. The information about their sociodemographic characteristics, lifestyle, nutrient intake and other factors were collected through questionnaire surveys and physical examinations. Grip strength was measured by using professional electronic grip dynamometer. Total skeletal muscle mass (TSM) was measured using bioelectrical impedance analysis, and TSM was adjusted by height squared and BMI to obtain TSM Ht2 and TSM BMI. The proportion of individuals with low muscle mass and strength was determined according to the recommended method by the Asian Working Group for Sarcopenia (AWGS). Descriptive analysis was conducted on the population and regional distribution characteristics of people with different muscle mass and grip strength. A generalized additive model was used to analyze the age-related trends of muscle mass and grip strength. Results:The age of 4 662 study subjects was (82.69±10.54) years, men accounted for 46.85% (2 184 cases) and Han Chinese accounted for 96.27% (4 488 cases). The M( Q1, Q3) of TSM, TSM Ht2 and TSM BMI in men were 23.30 (20.50, 26.20) kg, 9.02 (8.13, 9.89) kg/m 2, and 1.01 (0.90, 1.13) kg·(kg/m 2) -1, respectively, which were all higher than those in women [TSM: 18.20 (15.70, 20.70) kg, TSM Ht2: 8.18 (7.42, 9.07) kg/m 2 and TSM BMI: 0.79 (0.69, 0.90) kg·(kg/m 2) -1], the differences were significant (all P<0.001). The grip strength of men [ M( Q1, Q3): 24.50 (17.80, 30.80) kg] was higher than that of women [ M( Q1, Q3): 15.60 (11.10, 19.90) kg], the difference was significant ( P<0.001). Southern elderly men had lower TSM and TSM Ht2 compared with northern elderly men (all P<0.001), while there was no significant regional difference in TSM BMI ( P>0.05). Southern elderly women had higher TSM Ht2 and TSM BMI compared with northern elderly women (all P<0.001), while there was no significant regional difference in TSM ( P>0.05). Furthermore, according to the method recommended by AWGS, the elderly with low muscle mass and grip strength were characterized by older age, illiteracy, being unmarried/divorced/widowed, poor chewing ability, impaired activity of daily living and living in southern region. Conclusion:There were population and regional differences in muscle mass and grip strength in the older adults over 65 years in 18 longevity areas of China, and these differences showed decreasing trends with age.

Objective:To summarize the incidence of cerebral venous reflux (CVR) in patients with recent small subcortical infarct (RSSI) and explore its correlation with enlarged perivascular spaces (EPVS).Methods:Patients with RSSI in the lenticulostriate artery admitted to the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January 2019 to December 2022 were included. The baseline demographic data, medical history, and laboratory results of the patients were collected. CVR was assessed by time-of-flight magnetic resonance angiography. Patients were stratified into 2 groups based on the presence (CVR group) or absence of CVR (non-CVR group), and baseline characteristics as well as laboratory test results were compared between the 2 groups. The location and number of EPVS were evaluated using a visual grading scale, with EPVS with higher scores defined as high-grade EPVS (HEPVS). Simultaneous evaluation of cerebral white matter hyperintensities and lacunar infarctions was conducted, followed by intergroup comparisons. The relationship between EPVS and CVR was studied using multiple Logistic regression analysis.Results:A total of 571 patients with RSSI in the lentiform artery area were ultimately included, including 180 females (31.5%). Their age was (59.37±12.87) years. Among them, 73 patients (12.8%) exhibited CVR based on imaging findings, so the incidence of CVR was 12.8%. In comparison between the CVR group ( n=73) and the non-CVR group ( n=498), the proportion of females [21.9% (16/73) vs 32.9% (164/498), χ 2=3.578, P=0.059] was lower and the proportion of history of smoking [38.4% (28/73) vs 27.7% (138/498), χ 2=3.499, P=0.061] was higher in the CVR group, but without statistical significance. Additionally, the history of alcohol consumption [34.2% (25/73) vs 21.7% (108/498), χ 2=5.621, P=0.018] and the proportion of patients with concomitant HEPVS in the basal ganglia area [41.1% (30/73) vs 25.3% (126/498), χ 2=7.999, P=0.005] was higher in the CVR group with statistical significance. Multiple Logistic regression analysis showed that HEPVS in the basal ganglia region remained independently associated with CVR ( OR=1.988, 95% CI 1.190-3.320, P=0.009). Conclusion:EPVS in the basal ganglia region is significantly associated with CVR in the RSSI population, suggesting that venous dysfunction may be closely related to the formation of EPVS.
