Objective To investigate the relationship between high DNA stainability(HDS)and routine semen parameters.Methods Semen samples were collected from 396 men of childbearing age who were admitted to our department.Correlations of HDS with routine semen parameters and age were analyzed.Multiple linear regression analysis was performed to identify the routine semen parameters that had the greatest influence on HDS.The correlation of HDS and DNA fragmentation index(DFI)with routine semen parameters and age in 244 patients with teratozoospermia was analyzed.The 244 patients were divided into extremely severe,severe,moderate,and mild teratozoospermia groups,and differences in HDS,DFI,and routine semen parameters were compared among the four groups.Results HDS was negatively correlated with total sperm count,sperm concentration,sperm progressive motility,and normal sperm morphology rate(NSMR)(P<0.01).After adjusting for potential confounders,including total sperm count,sperm concentration,sperm progressive motility,NSMR,and DFI,NSMR had the most significant negative effect on HDS(P<0.05).In the 244 patients with teratozoospermia,HDS was negatively correlated with NSMR(P<0.01)and positively correlated with the percentage of sperm head and tail abnormalities(P<0.05),while DFI was positively correlated with the percentage of sperm tail abnormalities(P<0.01).There was a significant difference in the percentage of sperm head abnormalities among the four teratozoospermia groups.The more severe the malfor-mation,the higher the percentage of sperm head abnormalities was(P<0.001).HDS in the extremely severe teratozoospermia group was significantly higher than that in the mild and moderate teratozoospermia groups(P<0.05).No significant differences in DFI were found among the four groups(P>0.05).Conclusion HDS was closely correlated with routine semen parameters and was a crucial biomarker for assessing sperm quality,particularly the extent of sperm head abnormalities.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Objective To investigate the correlation between seminal plasma oxidation-reduction potential(ORP)and normalized ORP(nORP)with sperm DNA fragmentation index(DFI),high DNA staining(HDS),and motility parameters,and to explore whether these parameters can be used as biomarkers for evaluating male fertility potential.Methods A total of 309 men who attended the andrology clinic at the Department of Reproductive Medicine,General Hospital of Northern Theater Command,between October 2023 and December 2023,were selected in this study.We analyzed the correlation between seminal plasma ORP and nORP and parameters such as DFI using the electrode method,HDS,age,days of abstinence,semen volume,total sperm count,sperm concentration,sperm motility(forward motile sperm count,forward motile sperm percentage,non-forward sperm count,non-forward sperm percentage,immotile sperm count,immotile sperm percentage,and sperm motility rate),and motility indices(curvilinear velocity[VCL],straight-line velocity[VSL],average velocity[VAP],linear index[LIN],straightness index[STR],and wobble coefficient[WOB]).The nORP results were divided into three groups and analyzed in relation to each of the parameters mentioned above.A generalized linear regression model was used to assess the relationship between nORP and HDS,with smooth curve fitting performed to visualize this relationship.Results Pearson and Spearman correlation analyses revealed that both ORP and nORP were positively correlated with semen volume,percentage of immotile sperm,and DFI,but negatively correlated with forward motile sperm count,percentage of forward motile sperm,sperm motility rate,VSL,and VAP(P<0.05).Additionally,ORP was positively correlated with abstinence days and immotile sperm count(P<0.05)and negatively correlated with LIN,STR,and WOB(P<0.05).However,nORP was positively correlated with HDS(P<0.05),and negatively correlated with total sperm count,sperm concentration,non-forward sperm count,non-forward sperm percentage,immotile sperm count,and VCL(P<0.05).The nORP group showed significant differences in semen volume,total sperm count,sperm concentration,forward motile sperm count,forward motile sperm percentage,non-forward sperm count,non-forward sperm percentage,immotile sperm count,immotile sperm percentage,sperm motility rate,VCL,VSL,VAP,DFI,and HDS(P<0.05).A smooth curve fitting of nORP and HDS,adjusted for age and abstinence days,demonstrated a linear upward trend in nORP as HDS increased.Conclusion Both ORP and nORP are associated with sperm DFI and key motility parameters.Moreover,nORP is closely related to HDS,which reflects sperm maturity,offering a more comprehensive indicator of semen quality.Thus,nORP can be utilized as a biomarker for assessing male fertility potential.

Objective:To analyze the research trends and hotspots of anti-Müllerian hormones (AMH) from 2006 to 2020, and to provide reference for future research in related fields.Methods:Based on the PubMed database, the literatures related to AMH collected from January 1st, 2006 to December 31st, 2020 were retrieved, and the bibliometric method was used to analyze the relationship between each stage and AMH with every 5 years as the time node. The publication trends, high-frequency main MeSH/subheadings co-occurrence and research hotspots related to AMH were discussed and forecasted.Results:A total of 4 276 related literatures were retrieved in this paper, and the total number of published papers showed an increasing trend. Relevant research hotspots were gradually increasing. The core research from 2005 to 2010 was the biomarker effect of AMH; from 2011 to 2015 and 2016 to 2020, the core research hotspots were all AMH and polycystic ovary syndrome.Conclusion:While the research hotspots related to AMH have been continuously expanded and enriched, there are also certain changes and alternations, and some emerging hotspots still have the value and significance of further research. AMH type Ⅱ receptor and fertility preservation may become an emerging hotspot in this field in the future.
