Objective:To investigate the predictive value of color Doppler ultrasound combined with electrocardio-gram for right heart dys function in patients with pulmonary heart disease(PHD).Methods:A total of 100 PHD patients admitted in Dongcheng Branch of First Affiliated Hospital of Anhui Medical University between January 2020 and December 2023 were retrospectively analyzed.According to results of 6min walking test(6MWT),pa-tients were divided into good right heart function group(n=64,≥350m)and right heart dysfunction group(n=36,＜350m).The indexes of cardiac color ultrasound[isovolumic relaxation time(IVRT),isovolumetric contraction time(IVCT)and right ventricular Tei index],ECG[24h mean R-R interval standard deviation(SDNN),normal R-R interval standard deviation per 5min(SDANN)and the ratio of low frequency components to high frequency components(LF/HF)]were compared between two groups.Receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of color Doppler ultrasound,ECG and their combination for right heart dys-function in PHD patients.Spearman correlation coefficient was used to analyze the association of color Doppler ul-trasound,ECG and their combination with right heart dysfunction in PHD patients.Results:Compared with those in good right heart function group,patients in right heart dysfunction group had significant higher IVRT[(120.64±14.08)ms vs.(97.87±10.93)ms],IVCT[(84.28±12.33)ms vs.(71.92±10.61)ms]and Tei index[(0.85±0.11)vs.(0.63±0.07)](P＜0.001 all),and significant lower SDNN[(75.52±12.58)ms vs.(85.58±11.75)ms],SDANN[(63.86±10.92)ms vs.(76.75±11.71)ms]and LF/HF[(1.33±0.19)vs.(1.84±0.27)](P＜0.001 all).ROC curve indicated that the AUC of color Doppler ultrasound combined ECG in diagnosing right heart dysfunction in PHD patients was 0.911(95％CI 0.838～0.959),which was significantly higher than those of color Doppler ultrasound[0.775(95％CI 0.681～0.853),Z=2.404,P=0.016]and ECG[0.688(95％CI 0.588～0.777),Z=3.968,P=0.001]alone.Spearman correlation analysis indicated that there was a significant positive correlation of color Doppler ultrasound(r=0.547),ECG(r=0.375)and their combination(r=0.810)with right heart dysfunction in PHD patients(P＜0.001 all),and the correlation between combined detection and right heart dysfunction in PHD patients was significantly higher.Conclusion:Color Doppler ultrasound combined with ECG possesses high diagnostic performance for right heart dysfunction in PHD patients.

Objective To investigate the improvement effect of microsurgical varicocelectomy with vein ligation on scrotal pain and the related factors affecting the improvement of postoperative pain.Methods A retrospective analysis was conducted on the clinical data of 110 patients who underwent microsurgical inguinal varicocelectomy in Central Theater Command General Hospital from November 2021 to June 2023.The degree of pain before and after the operation was evaluated by Numerical Rating Scale(NRS).The pain relief rate,the occurrence of postoperative complications and the overall satisfaction of patients were evaluated.The semen and hormone levels of the patients before and after the operation were analyzed.Univariate and multivariate linear regression analyses were performed to investigate the relationship between clinical variables and postoperative 7-day NRS score.Results The average number of ligated veins during the operation was(6.60±3.76);postoperative satisfaction of patients was(4.23±1.08)points;complications occurred in 7 patients after the operation;after 3 months of follow-up,the overall pain relief rate was 92.73%(102/110).Compared with those before the operation,the NRS score of the patients significantly decreased 7 days after the operation,and the levels of total sperm motility,prolactin and testosterone increased 3 months after the operation,while the levels of serum follicle-stimulating hormone(FSH)and luteinizing hormone(LH)decreased,the differences were statistically significant(P<0.05).The univariate and multivariate linear regression analyses showed that the Dubin-Amelar classification of varicocele(P=0.045),operation time(P=0.049),and number of ligated veins(P=0.024)were significantly correlated with the change of postoperative 7-day NRS score.Patients with 1 to 4,5 to 10,and>10 intraoperative ligation veins were analyzed,and pain relief rates 3 months after the operation were 77.78%(28/36),100%(58/58),and 100%(16/16),respectively,with statistically significant difference(χ2=17.732,P<0.001).Conclusion Microsurgical varicocelectomy can effectively relieve scrotal pain and improve semen quality.Moreover,the relief of postoperative pain is related to the Dubin-Amelar classification of varicocele,the sufficient number of ligated spermatic veins,and the surgical experience of the surgeon.

Objective:To investigate the epidemiological dynamics and spatiotemporal diffusion trend of brucellosis in China from 2010 to 2024.Methods:Data on reported human brucellosis cases in mainland China from January 1, 2010, to December 31, 2024, were collected via the"China Information System for Disease Control and Prevention", including detailed information on the date of onset, gender, age, occupation, and residential address of the cases. The Joinpoint regression and spatial interpolation techniques were used to investigate the spatiotemporal dynamics and population distribution characteristics of human brucellosis in pastoral/semi-pastoral areas and other regions, as well as urban and rural areas, and explore the epidemic trends of the disease.Results:From 2010 to 2024, pastoral/semi-pastoral regions reported 252 094 brucellosis cases, with a mean annual incidence rate of 36.57±7.28 per 100 000. In contrast, other regions cumulatively recorded 519 748 cases during the same period, demonstrating a significantly lower mean annual incidence rate of 2.54±0.74 per 100 000. The incidence rate of human brucellosis in pastoral/semi-pastoral regions exhibited a declining-rebounding-declining trend. Specifically, the incidence rate decreased significantly from 2010 to 2017 (APC=-7.20; P<0.001) and increased notably from 2017 to 2021 (APC=18.00; P=0.015) with a decline again from 2021 to 2024 (APC=-7.53; P=0.027). In other regions, the incidence rate showed a fluctuating upward trend. Specifically, the incidence rate increased significantly from 2010 to 2015 (APC=20.37; P<0.001) and decreased notably from 2015 to 2018 (APC=-21.78; P<0.001), followed by an increase again from 2018 to 2024, a significant upward trend in incidence rate from 2018 to 2021 (APC=26.73; P<0.001) and a non-significant decline from 2021 to 2024 (APC=-0.99; P=0.735), resulting in the maintenance of a relatively high incidence level. Rural areas demonstrated significantly higher brucellosis incidence rates than urban settings (all P<0.001). Brucellosis exhibited a diffusion trend from the northern epidemic areas of China to neighboring regions, along with sporadic diffusion in southern regions between 2010 and 2024. The age structure of patients in pastoral/semi-pastoral areas differed significantly from that in other regions. Specifically, in pastoral/semi-pastoral areas, the incidence rate was higher among the 35-49 age groups, while in other regions, the incidence rate was higher among those aged 55-64. Conclusion:There are notable disparities in the incidence of human brucellosis between pastoral/semi-pastoral areas and other regions in China. Human brucellosis exhibits a diffusion trend from the northern epidemic areas of China to neighboring regions, along with sporadic diffusion in southern regions.

Purpose: To investigate the therapeutic potential of eliminating insulin-like growth factor-binding protein 5 (IGFBP5) expression in improving erectile function in mice with cavernous nerve injury (CNI)-induced erectile dysfunction (ED). Materials and Methods: Eight-week-old male C57BL/6 mice were divided into four groups: a sham-operated group and three CNI-induced ED groups. The CNI-induced ED groups were treated with intracavernous injections 3 days before the CNI procedure.These injections included phosphate-buffered saline, scrambled control short hairpin RNA (shRNA), or shRNA targeting mouse IGFBP5 lentiviral particles. One week after CNI, erectile function was evaluated and the penile tissue was then harvested for histological examination and western blot analysis. Additionally, the major pelvic ganglia (MPG) and dorsal root ganglia (DRG) were cultured for ex vivo neurite outgrowth assays. Results: Following CNI, IGFBP5 expression in the cavernous tissues significantly increased, reaching its peak at day 7. First, ablation of IGFBP5 expression promotes neurite sprouting in MPG and DRG when exposed to lipopolysaccharide. Second, ablating IGFBP5 expression in CNI-induced ED mice improved erectile function, likely owing to increased neurovascular contents, including endothelial cells, pericytes, and neuronal processes. Third, ablating IGFBP5 expression in CNI-induced ED mice promoted neurovascular regeneration by increasing cell proliferation, reducing apoptosis, and decreasing Reactive oxygen species production. Finally, western blot analysis demonstrated that IGFBP5 ablation attenuated the JNK/c-Jun signaling pathway, activated the PI3K/AKT signaling pathway, and increased vascular endothelial growth factor and neurotrophic factor expression. Conclusions Ablating IGFBP5 expression enhanced neurovascular regeneration and ultimately improved erectile function in CNI-induced ED mice.

Objective:To utilize single-nucleus RNA sequencing(snRNA-seq) technology to investigate the primary cell subpopulations in human limb venous malformations (VMs) tissue and the role of the key gene RhoJ.Methods:Surgical resection specimens of VMs tissues and surrounding normal vein tissues were collected from 100 clinically diagnosed and screened patients with limb VMs at the Department of Hemangioma Surgery of the Third Affiliated Hospital of Zhengzhou University from January 2021 to December 2023. (1) Transcriptome analysis: Three patient samples were randomly selected for snRNA-seq studies, with the surgically removed VMs tissue serving as the experimental group and the surrounding normal vein tissue as the control group. A gene expression matrix for cell nuclei was established, followed by data quality control, dimensionality reduction, clustering, and cell type annotation. Cell-to-cell communication analysis was performed using the R language CellChat package to identify dominant cell subpopulations. The FindMarkers function was utilized to screen for differentially expressed genes (DEGs) between the dominant cell subpopulations of the experimental and control groups, and functional enrichment analysis was conducted. (2) Tissue experiments: An additional 35 patient samples from both the experimental and control groups were randomly selected. The mRNA and protein expression levels of the RhoJ gene were measured using real-time quantitative PCR (RT-qPCR) and Western blotting, respectively. (3) Validation experiments with human umbilical vein endothelial cells (HUVECs): HUVECs were transfected with pcDNA3.1-NC (blank control) and pcDNA3.1-RhoJ (plasmid expression vector carrying the RhoJ gene), respectively. The biological behavior differences between the two groups of cells were examined using the CCK-8 cell proliferation assay, Transwell invasion assay, and Matrigel angiogenesis assay. Measurement data conforming to a normal distribution were expressed as Mean±SD, and comparisons between the two groups were performed using an independent samples t-test. Results:Through CellChat intercellular communication analysis, it was discovered that endothelial cells were the predominant cell subpopulation in both the experimental and control groups, exhibiting strong communication links with other cell subpopulations. In the analysis of DEGs, it was found that the RhoJ gene in endothelial cells was significantly involved in the biological processes of angiogenesis and regulation. In tissue experiments, RT-qPCR and Western bloting results indicated that the relative expression levels of RhoJ mRNA (4.48±1.29 vs. 1.01±0.17) and protein (1.22±0.03 vs. 0.51±0.20) in the experimental group were significantly higher than those in the control group, with statistically significant differences ( P<0.01 for both). The results of the HUVECs validation experiment showed that the cell proliferation, invasion, and angiogenesis abilities of the pcDNA3.1-RhoJ group were significantly enhanced compared to the pcDNA3.1-NC group. Conclusion:Endothelial cells represent the dominant cell subpopulation during the occurrence and locally invasive progression of VMs, playing a crucial role in this process. The RhoJ gene is significant in regulating the biological behavior of VMs endothelial cells.

OBJECTIVE: To investigate the potential mechanism by which electroacupuncture (EA) induces macrophage polarization to promote muscle satellite cell proliferation and differentiation, accelerating the repair of acute skeletal muscle injury. METHODS: Forty-two SPF-grade SD rats were randomly divided into three groups: a blank group (n=6), a model group (n=18), and an EA group (n=18). The model and EA groups established acute blunt contusion model of the right gastrocnemius muscle using a self-made striking device. From day 1 after modeling, rats in the EA group received EA at "Chengshan" (BL57) and "Yanglingquan" (GB34) on the right side, using disperse-dense wave with a frequency of 2 Hz/100 Hz and a current of approximately 2 mA. The EA treatment was administered once daily for 30 minutes for 3, 7, or 14 days based on the designated sampling time points. Gait analysis was performed using the Cat Walk XT^TM system. Hematoxylin-eosin (HE) staining was used to observe the morphological changes in the gastrocnemius muscle. Masson staining was applied to evaluate collagen fiber content. Immunofluorescence was used to detect the expression of proliferating cell nuclear antigen (PCNA) in muscle satellite cells. Immunohistochemistry was used to assess the expression levels of CD68 and CD206, markers of macrophages. Serum levels of pro-inflammatory cytokines (TNF-α, IL-1β) and anti-inflammatory cytokines (IL-10, IL-13) were detected using ELISA. RESULTS: Compared with the blank group, the model group showed a significant reduction in average movement speed on days 3 and 7 after modeling (P<0.05), and a decrease in the right hind limb stride length on day 3 (P<0.05). Compared with the model group, the EA group showed increased average movement speed and right hind limb stride length on day 7 (P<0.05). In the blank group, the gastrocnemius muscle on the right side showed uniform and consistent inter-fiber spacing, with neatly and regularly arranged muscle cells. In contrast, the model group exhibited enlarged inter-fiber spacing, edema, and significant infiltration of red blood cells and inflammatory cells, with progressively increasing fibrosis over time. By day 14 after modeling, the EA group showed a return to baseline levels of inflammatory cell infiltration, and the degree of fibrosis was significantly lower than that observed in the model group. Compared with the blank group, the ratio of collagen fibers in the gastrocnemius muscle of the model group increased significantly on days 3, 7, and 14 after modeling (P<0.05). Compared with the model group, the EA group exhibited a lower collagen fiber ratio on days 3, 7, and 14 (P<0.05). Compared with the blank group, PCNA positive expression in the gastrocnemius muscle of the model group was significantly increased on days 3, 7, and 14 after modeling (P<0.05). Compared with the model group, the EA group exhibited significantly higher PCNA positive expression on days 3 and 7 (P<0.05). Compared with the blank group, the model group showed a significant increase in CD68-positive macrophage expression in the gastrocnemius muscle on day 3 after modeling (P<0.05), while CD206-positive macrophage expression increased on days 3, 7, and 14 (P<0.05). Compared with the model group, CD68 expression was significantly lower in the EA group on day 3 (P<0.05), whereas CD206 expression was significantly higher on days 3 and 7 (P<0.05), peaking on day 7 with CD206 expression. Compared with the blank group, serum TNF-α levels were significantly elevated in the model group on days 3 and 7 after modeling (P<0.05), while serum IL-1β levels were increased on days 3, 7, and 14 (P<0.05). Serum IL-10 and IL-13 levels were significantly higher on day 7 after modeling (P<0.05). Compared with the model group, the EA group exhibited lower serum TNF-α level on day 3 (P<0.05) and reduced serum IL-1β levels on days 3 and 7 (P<0.05), while serum IL-10 and IL-13 levels were significantly increased on day 7 (P<0.05). CONCLUSION EA could promote the repair of acute blunt contusion-induced gastrocnemius muscle injury by regulating the proliferation and differentiation of muscle satellite cells. This process is closely related to macrophage polarization.
