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.

ObjectiveTo investigate the trends in diabetes mortality and potential years of life lost (PYLL) among residents of Huangpu District, Shanghai from 1993 to 2021, to analyze the long-term trends of diabetic patients with different characteristics and to provide a reference for scientific prevention and control of diabetes in aging urban areas. MethodsDiabetes mortality data were obtained from the Huangpu District cause of death registration records in the Shanghai death cause registration system. Indicators such as crude mortality rate, standardized mortality rate, potential years of life lost (PYLL), average years of life lost (AYLL), annual percentage change (APC), and average annual percentage change (AAPC) were used to analyze diabetes-related mortality and life loss. Statistical analyses were performed using software SPSS 21.0 and Joinpoint 5.0.2. ResultsFrom 1993 to 2021, the average annual crude mortality rate of diabetes in Huangpu District was 46.56/100 000, and the average annual standardized mortality rate was 20.44/100 000. The crude mortality rate and standardized mortality rate of diabetes for female residents were higher than those for males. The crude mortality rate showed an overall increasing trend [AAPC=2.81% (95%CI: 0.20%‒5.49%), P<0.05], while the increase in standardized mortality rate significantly slowed [AAPC=0.15% (95%CI: -2.27%‒2.63%)], P<0.05]. The mortality rate rose rapidly in the 70‒74 years age group and peaked in the 85‒ years age group (607.69/100 000). Diabetes accounted for a cumulative PYLL of22 741 person-years, with an average annual AYLL of 1.88 years and an average annual potential years of life lost rate (PYLLR) of 0.82‰. Male residents had higher PYLL, AYLL, and PYLLR than females. ConclusionDiabetes mortality rates in Huangpu District have increased year by year, resulting in significant life loss. However, the age-standardized mortality rate increase has markedly slowed. Efforts should focus on elderly diabetic patients aged ≥70 years, by leveraging platforms such as community-based chronic disease health support centers, efforts should be made to enhance diabetes screening service for middle-aged and elderly residents. Consequently, elderly diabetic patients’ awareness of diabetes and responce to related complications is improved, which would be conducive to controling the progression of complications and reducing the mortolity risk of diabetes.

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.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Objective:To explore the effect of staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair.Methods:From January 2021 to December 2022, convenience sampling was used to select 73 patients who underwent arthroscopic rotator cuff repair in the Department of Hand Surgery at Affiliated Hospital of Nantong University as participants. According to the random number table method, patients were divided into a control group ( n=36) and an observation group ( n=37). Control group received routine rehabilitation nursing, while observation group received staged rehabilitation nursing. The University of California, Los Angeles (UCLA) Shoulder Rating Scale score, American Shoulder and Elbow Surgeons (ASES) Rating Scale score, Constant-Murley Shoulder Scale score, and complications during rehabilitation were compared between two groups of patients before and six months after intervention. Results:Six months after surgery, both groups showed an increase in UCLA scores and ASES scores compared to before the intervention ( P<0.05), and the scores of observation group were higher than those of control group, with statistical differences ( P<0.05). Six months after surgery, the Constant-Murley Shoulder Scale scores for daily life and shoulder range of motion in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05). During the rehabilitation period, the incidence of complications in observation group was lower than that in control group with a statistical difference ( P<0.05) . Conclusions:Staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair shows significant effects and can effectively promote patient recovery.

Objective To determine the effect of thrombus aspiration combined with intracoronary injection of recombinant human TNK tissue type plasminogen activator(rhTNK-tPA)on micro-circulation and cardiac function during primary PCI in elderly patients with acute myocardial in-farction(AMI).Methods A retrospective study was conducted on 90 elderly patients with STEMI undergoing primary PCI in Tianjin Third Central Hospital from January 2021 to October 2023.According to their treatment strategies,they were divided into simple suction group(n=46)and combination group(n=44).The suction group received a suction catheter for thrombus aspiration within the coronary artery,while the combined group got a suction catheter for thrombus aspira-tion within the infarct related blood vessels,and then received a local injection of rhTNK-tPA into the lesion through the suction catheter.Their general data,proportion of ST segment resolution(STR)≥70％at 90 min after surgery,postoperative TIMI blood flow grade,postoperative TIMI myocardial perfusion grade(TMPG),corrected TIMI frame count(CTFC)and cardiac ultrasound indicators as well as the incidence of adverse cardiac events during hospitalization were compared between the two groups.Results Larger proportions of postoperative STR ≥70％,postoperative TIMI blood flow grade 3 and TMPG grade 3,and lower CTFC were observed in the combination group than the suction group(P＜0.05).In 1 week after surgery,the simple suction group had lower left ventricular ejection fraction[LVEF,(52.5±6.2)％vs(58.3±6.4)％,P＜0.05],but larger left ventricular diameter(LVD,44.1±3.9 mm vs 51.9±2.5 mm,P＜0.05)than the com-bined group.The incidence of MACE during hospitalization was obviously lower in the combined group than the suction group(20.5％vs 37.0％,P＜0.05).Conclusion Combined intracoronary injection of rhTNK-tPA based on thrombotic aspiration can effectively reduce the coronary thrombus burden,improve myocardial microcirculation perfusion,reduce the incidence of MACE during hospitalization,and not increase the risk of bleeding in elderly STEMI patients.

Objective:To evaluate the effectiveness of correcting breast ptosis using the rotational filling of an inferolaterally pedicled tongue-shaped parenchymal flap via a double periareolar incision.Methods:A retrospective study was conducted on 34 female patients (68 breasts) with breast ptosis treated at the Department of Plastic Surgery at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from January 2016 to June 2023. The patients＇ ages ranged from 23 to 53 years, with an average of (37.4±7.9) years. All patients underwent correction of breast ptosis using an inferolaterally pedicled tongue-shaped parenchymal flap via a double periareolar incision. Pre-operative and post-operative measurements were taken to assess the corrective outcomes, including mammary base width (MBW), areola diameter (AD), nipple-to-nipple distance (NN), suprasternal notch-to-nipple distance (SSN-N), nipple-to-inframammary fold distance (N-IMF), and thoracic circumference at the nipple level (TN). Patients＇ satisfaction was assessed using the BREAST-questionnaire (BREAST-Q) module.Results:Postoperative first-stage wound healing was achieved in all 34 patients without complications such as hematoma, infection, or nipple necrosis. The follow-up period ranged from 6 to 60 months, with a median of 12 months. Early postoperative observations showed periareolar folds, which disappeared within 3 to 6 months in 31 cases, while mild periareolar folds, persisted for up to 12 months in 3 cases. Four patients reported reduced nipple sensation postoperatively. Measurements showed a statistically significant increase in TN and a reduction in NN, SSN-N, AD, N-IMF, and MBW compared to preoperative values (all P<0.001). BREAST-Q scores indicated significant improvements in satisfaction with breasts, psychosocial well-being and physical well-being, with preoperative scores of (21.6±8.9), (42.4±11.9) and (49.7±12.9) scores increasing to (82.3±8.5), (81.9±8.1) and (81.2±8.3) scores, respectively (all P<0.001). Conclusions:The double periareolar incision technique with rotational filling of an inferolaterally pedicled tongue-shaped glandular flap is a safe and effective method for correcting breast ptosis.
