Insulin-like growth factor 2 (IGF2) is a critical endocrine mediator implicated in male reproductive physiology. To investigate the correlation between IGF2 protein levels and various aspects of male infertility, specifically focusing on sperm quality, inflammation, and DNA damage, a cohort of 320 male participants was recruited from the Women's Hospital, Zhejiang University School of Medicine (Hangzhou, China) between 1 st January 2024 and 1 st March 2024. The relationship between IGF2 protein concentrations and sperm parameters was assessed, and Spearman correlation and linear regression analysis were employed to evaluate the independent associations between IGF2 protein levels and risk factors for infertility. Enzyme-linked immunosorbent assay (ELISA) was used to measure IGF2 protein levels in seminal plasma, alongside markers of inflammation (tumor necrosis factor-alpha [TNF-α] and interleukin-1β [IL-1β]). The relationship between seminal plasma IGF2 protein levels and DNA damage marker phosphorylated histone H2AX (γ-H2AX) was also explored. Our findings reveal that IGF2 protein expression decreased notably in patients with asthenospermia and teratospermia. Correlation analysis revealed nuanced associations between IGF2 protein levels and specific sperm parameters, and low IGF2 protein concentrations correlated with increased inflammation and DNA damage in sperm. The observed correlations between IGF2 protein levels and specific sperm parameters, along with its connection to inflammation and DNA damage, underscore the importance of IGF2 in the broader context of male reproductive health. These findings lay the groundwork for future research and potential therapeutic interventions targeting IGF2-related pathways to enhance male fertility.

The aim of this investigation was to determine the optimal storage medium for testicular hypothermic transportation and identify the ideal concentration for the application of the protective agent 5-aminolevulinic acid (5-ALA). Furthermore, this study aimed to explore the underlying mechanism of the protective effects of 5-ALA. First, we collected and stored mouse testicular fragments in different media, including Hank's balanced salt solution (HBSS; n = 5), Dulbecco's Modified Eagle Medium/Nutrient Mixture F-12 (DMEM/F12; n = 5), and alpha-minimum essential medium (αMEM; n = 5). Storage of testicular tissue in HBSS preserved the integrity of testicular morphology better than that in the DMEM/F12 group ( P < 0.05) and the αMEM group ( P < 0.01). Testicular fragments were subsequently placed in HBSS with various concentrations of 5-ALA (0 [control], 1 mmol l -1 , 2 mmol l -1 , and 5 mmol l -1 ) to determine the most effective concentration of 5-ALA. The 2 mmol l -1 5-ALA group ( n = 3) presented the highest positive rate of spermatogonial stem cells compared with those in the control, 1 mmol l -1 , and 5 mmol l -1 5-ALA groups. Finally, the tissue fragments were preserved in HBSS with control ( n = 3) and 2 mmol l -1 5-ALA ( n = 3) under low-temperature conditions. A comparative analysis was performed against fresh testes ( n = 3) to elucidate the underlying mechanism of 5-ALA. Gene set enrichment analysis (GSEA) for WikiPathways revealed that the p38 mitogen-activated protein kinase (MAPK) signaling pathway was downregulated in the 2 mmol l -1 5-ALA group compared with that in the control group (normalized enrichment score [NES] = -1.57, false discovery rate [FDR] = 0.229, and P = 0.019). In conclusion, these data suggest that using 2 mmol l -1 5-ALA in HBSS effectively protected the viability of spermatogonial stem cells upon hypothermic transportation.

The patient, a 20-day-old male, was admitted due to respiratory distress that had persisted for 20 days after birth. The main clinical manifestations included gradually worsening respiratory distress and edema. The patient received treatment including mechanical ventilation and diuretics. Echocardiography indicated cardiomegaly, pulmonary hypertension, and heart failure. A comprehensive systemic examination revealed a significant blowing vascular murmur upon auscultation over the anterior fontanelle and bilateral temporal regions. Further imaging studies including cranial magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography showed marked dilation of the superior sagittal sinus, transverse sinus, and sigmoid sinus, leading to a definitive diagnosis of dural arteriovenous fistula. After a multidisciplinary consultation, the patient underwent cerebral angiography and partial embolization of the left parietal arteriovenous fistula. Postoperatively, the patient was treated with positive inotropes, diuretics, and fluid restriction. Ultimately, the patient was weaned off the ventilator and discharged in improved condition. This article reports a case of neonatal dural arteriovenous fistula presenting with respiratory distress and discusses the multidisciplinary approach to managing this condition, which aids in early disease recognition and guides clinical decision-making.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

To evaluate the accuracy of contrast-enhanced ultrasound diagnostic reports for pancreatic lesions. In this retrospective study, we included patients who underwent contrast-enhanced ultrasound examination of pancreatic lesions at Peking Union Medical College Hospital from January 2017 to December 2022 and received a confirmed pathological diagnosis. Using pathological diagnosis as the gold standard, the study evaluated the accuracy of contrast-enhanced diagnostic ultrasound. It also analyzed the misdiagnosis of contrast-enhanced ultrasound in diagnosing various pathological types of pancreatic lesions. Of the 859 patients who met inclusion and exclusion criteria, 489 were male(56.9%) and 370 were female(43.1%).Their age ranged from 16 to 85 years, with a median age of 60(53, 66) years. Except for 47 pancreatic space-occupying lesions that were difficult to categorize as either benign or malignant, a total of 812 cases were included in the diagnostic efficacy analysis of benign and malignant lesions. The results suggested that the diagnostic sensitivity and specificity of contrast-enhanced ultrasound for pancreatic malignant lesions were 98.3%(95% CI: 97.1%-99.1%) and 79.0%(95% CI: 70.1%-86.4%), AUC was 0.887(95% CI: 0.863-0.908), positive and negative predictive value were 96.9%(95% CI: 95.6%-97.9%) and 87.4%(95% CI: 79.6%-92.4%), positive and negative likelihood ratio were 4.69(95% CI: 3.24-6.80) and 0.02(95% CI: 0.01-0.04). The diagnostic accuracy rate of contrast-enhanced ultrasound for diagnosing benign and malignant pancreatic lesions was 95.8%. Of the 859 lesions examined, 48 cases were misdiagnosed by contrast-enhanced ultrasound, with a misdiagnosis rate of 5.6%(48/859), including 7 cases(0.8%) of undetermined diagnosis, while the diagnostic accuracy of pancreatic ductal adenocarcinoma was as high as 98.8%. No complications occurred in any of the patients. Contrast-enhanced ultrasound is a safe and effective imaging method for evaluating microvascular perfusion in various pancreatic lesions. It has significant clinical value in diagnosing both benign and malignant pancreatic lesions, particularly in diagnosing pancreatic ductal adenocarcinoma.

Through a compound induction method, combined with neurobehavioral, macroscopic characterization and objective pathological evaluation indicators, a murine depression model of liver depression transforming into fire syndrome was constructed and confirmed. The model was constructed using a combination of sleep deprivation, light exposure, and alternate-day food deprivation. Evaluation was conducted at three levels: face validity, constructs validity, and predictive validity. The establishment of the liver depression transforming into fire syndrome depression model was further validated through the counterproof of traditional Chinese medicine formulas. In terms of face validity, compared to the control group, mice in the model group exhibited typical depressive symptoms in neurobehavioral assessments; the general observation of the model group mice reveals disheveled and lackluster fur, along with delayed and easily agitated responses. Additionally, there is a substantial increase in water consumption. In the sleep phase detection of mouse, the model group showed a significant increase in the proportion of time spent in the wake phase during sleep, accompanied by a significant decrease in the proportions of time spent in both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep phases. There are significant differences in physiological indicators such as average blood flow velocity, blood flow rate, tongue, urine, and claw color (r values) in the internal carotid artery. Structural validity demonstrated that levels of 5-hydroxytryptamine (5-HT), dopamine (DA), and

The aim of this study was to investigate the impact of overexpressing 70-kD heat shock pro-teins(Hsp70)on glycolysis in C2C12 cells during myogenesis and adipogenesis.Using C2C12 cells as the research material,adenovirus was used to overexpress the Hsp70 gene,and changes in the expression of glycolytic genes were detected using fluorescence quantitative PCR and Western blotting techniques.The study indicated that during C2C12 cell myogenic differentiation,the expression trend of the Hsp70 gene was consistent with that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,suggesting a relationship between Hsp70 and the glycolytic pathway during myogenic differentiation.Overexpression of Hsp70 in the later stages of myogenic differentiation significantly upregulated the expression of Gsk3β,Pkm,Prk-ag3,and Pfkm genes(P<0.05),with no significant impact on Hk-2 gene expression(P>0.05).Dur-ing C2C12 cell adipogenic induction,the expression trend of the Hsp70 gene was similar to that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,indicating a relationship between Hsp70 and the glycolytic path-way during adipogenic induction.Following Hsp70 overexpression,in the later stages of adipogenic in-duction,the number of lipid droplets was significantly higher compared to the control group,with a sig-nificant upregulation of Gsk3β,Pkm,Prkag3,and Pfkm gene expression(P<0.05),while Hk-2 gene expression was not significantly affected(P>0.05).In conclusion,Hsp70 in C2C12 cells in myogenic and adipogenic states promoted the breakdown of glycogen into 6-phospho-glucose,thereby enhancing the glycolytic pathway,providing insights into the functional role of the Hsp70 gene in glycolysis in C2C12 cells.
