Chronic epididymitis (CE) is a long-standing inflammatory condition of the epididymis caused by unresolved acute infections, chronic infections, medication use, or other factors. Clinically, it is characterized by persistent dull pain or a dragging sensation in one or both sides of the scrotum. The disease course typically exceeds three months and is marked by insidious onset and recurrent episodes. Current studies suggest that CE may disrupt the epididymal microenvironment through multiple pathological processes, including local inflammatory responses, oxidative stress, fibrotic remodeling, and autophagy. These alterations impair sperm maturation, transport, and capacitation, thereby contributing to male reproductive dysfunction and infertility. This review summarizes the major etiologies and pathophysiological characteristics of CE and its impact on male reproductive function. It focuses on the roles of inflammatory cytokines and related signaling pathways, oxidative stress mechanisms, and fibrotic progression in the pathogenesis of CE. Moreover, it explores targeted therapeutic strategies based on these mechanisms, aiming to provide a theoretical basis for identifying key molecular targets and signaling pathways involved in CE-induced male reproductive impairment.

Objective The aim of this study is to systematically analyze the therapeutic mechanisms of Wuzi Yuye Decoction in diabetic oligoasthenozoospermia based on network pharmacology and animal experiments.Methods Active components and therapeutic targets of Wuzi Yuye Decoction were screened by integrating multiple databases,and their inter-section with diabetic oligoasthenozoospermia-related targets was obtained.Common targets were identified using the Venny platform,and protein-protein interaction(PPI)networks were constructed via the STRING database.And key targets were screened through topological analysis with Cytoscape.Gene Ontology(GO)functional enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses were performed using the DAVID platform.A mouse model of diabetic oligoasthenozoospermia was established by high-fat diet combined with streptozotocin induction,followed by intervention with Wuzi Yuye Decoction.Body weight,testicular index,and sperm quality were assessed,while histopathological changes were evaluated by HE staining and transmission electron microscopy(TEM).In addition,ELISA,oxidative stress assays and Western blot were used to verify the changes in key pathway-related proteins.Results A total of 36 common targets were identified,including key nodes such as TNF,IL6 and IL1B.Enrichment analysis indicated that these targets were sig-nificantly involved in inflammatory responses,oxidative stress,autophagy-apoptosis regulation and reproduction-related pathways.Animal experiments confirmed that Wuzi Yuye Decoction markedly improved testicular mass and sperm motility in diabetic mice,reduced the levels of AGE,TNF-α,IL-6 and IL-1β in testicular tissues,alleviated oxidative stress damage,and restored autophagic flux and blood-testis barrier function by inhibiting the RAGE/NF-κB/mTOR signaling axis.Conclusion Wuzi Yuye Decoction improves the pathological progression of diabetic oligoasthenozoospermia by synergistically modulating multiple targets,including inflammation inhibition,antioxidant effects,autophagy regulation,and related pathways.

As the most common phenotype of type 1 neurofibromatosis(NF1),plexiform neurofibromas(pNF)exhibit early asymptomatic presentation but multisite involvement,with a risk of progression.Imaging serves as vital tool for evaluation and management of NF1-associated pNF.The progresses of imaging for evaluating NF1-related pNF were reviewed in this article.

Objective To explore the risk factors of acute respiratory failure(ARF)in adult patients with community-acquired pneu-monia(CAP),and thereby construct and validate the efficacy of nomogram model.Methods The clinical and laboratory data of 172 adult CAP patients admitted to Taikang Xianlin Drum Tower Hospital affiliated to Nanjing University School of Medicine from January 2018 to December 2021 were retrospectively collected.The patients were divided into two groups based on whether they had concurrent ARF.After the comparison for the differences of single factor between the two groups,collinearity analysis was assessed.The risk fac-tors were then screened by binary logistic regression analysis with forward stepwise regression method.A nomogram model was subse-quently constructed and the discrimination and accuracy of the model were evaluated by ROC and colibration curves.Results Among the 172 CAP patients,53 cases(30.8％)developed ARF.The results of univariate analysis showed that the CAP patients with concur-rent ARF group had higher age,CURB-65 score and inflammatory markers than the non-concurrent ARF group,and the incidence of complex infection(culturing two or more pathogenic bacteria)was high.The values of CRP(C-reactive protein)and BUN/Alb(blood urea nitrogen/albumin)were significantly different between the two groups(53.910[25.900,101.200]vs.23.300[6.800,48.930],0.231[0.160,0.302]vs.0.123[0.089,0.171],P＜0.05).Multivariate analysis indicated:glucose(Glu)≥6.06 mmol/L(odds ra-tio(OR):2.737,95％confidence interval(CI):1.116-7.037),AST(aspartate aminotransferase)≥22.5 U/L(OR:4.291,95％CI:1.779-11.120),fibrinogen(Fib)≤3.83 g/L(OR:3.955,95％CI:1.631-10.237),uric acid(UA)188.07 μmol/L(OR:4.617,95％CI:1.859-12.489),BUN/Alb≥0.15 mmol/g(OR:6.381,95％CI:2.423-18.513),total number of multicomor-bidity≥3(OR:6.191,95％CI:2.088-21.905)were the risk factors(P＜0.05).All the screened indicators were incorporate into the nomogram model and its efficacy was verified.The results showed that the area under the curve of the model was 0.888[95％CI:0.840-0.935](P＜0.05),the sensitivity was 0.868,and the specificity was 0.790.The calibration curve showed that the predicted probability of adult CAP patients-associated with ARF was in good consistency with the observed probability(Briser Score:0.125;H-L test:x2=7.563,P=0.477).Conclusion The established model has a good ability to predict adult CAP associated with ARF,and can provide a reference basis for early clinical prediction and intervention treatment.

Objective To investigate the expression and role of T cell immunoglobulin and mucin domain-containing protein 3(Tim-3)in the pathogenesis of experimental autoimmune uveitis(EAU).Methods A total of 12 male C57BL/6J mice,aged 4 to 5 weeks,were selected and divided into the control group(n=3)and the experimental group(n=9)using a random number table.The control group(modeling time point:0 days after modeling)received no treatment,while the experimental group was induced to establish an EAU model(divided into three subgroups according to the modeling time points:7 days,14 days,and 21 days after modeling,with 3 mice in each subgroup).Firstly,the interphotoreceptor retinoid-binding protein 651-670 and complete Freund's adjuvant were fully mixed and emulsified.Then,the emulsion was subcutaneously injected into the two thighs,tail base,and neck of mice in the experimental group(each mouse received 200 μL of immune emulsion containing 500 pg of interphotoreceptor retinoid-binding protein 651-670).Subsequently,each mouse in the experimental group was also intraperitoneally injected with 1 μg of pertussis toxin.The anterior segment and fundus of mice in each group were observed and photographed under a slit-lamp microscope.The clinical and histopatho-logical scoring of these mice was conducted according to the Caspi grading scale based on the severity of inflammation.The serum levels of IFN-γ and IL-17 were measured using the enzyme-linked immunosorbent assay(ELISA),while the mRNA expression of Tim-3 in the spleen and ocular tissues was detected using the real-time quantitative polymerase chain reaction(RT-qPCR).Western blot was employed to detect the protein expression of Tim-3,and immunohistochemistry was used to examine the protein expression of Tim-3 in the spleen tissue.Statistical analysis was performed using GraphPad Prism 9.0.Results The clinical scores of the anterior segment,fundus,and histopathology of the mice increased over time after modeling,with statistically significant differences among these groups(P＜0.05).The serum levels of IFN-γ and IL-17 in the mice also increased over time after modeling,with statistically significant differences among these groups(P＜0.05).The relative mRNA expression of Tim-3 in the spleen and ocular tissues of the mice decreased over time after modeling,with statistically significant differences among these groups(P＜0.05).The protein expression of Tim-3 in the ocular and spleen tissues showed the same pattern as its mRNA expression.Conclusion The expression of Tim-3 decreases with the exacerbation of inflammation in the progression of EAU,suggesting that Tim-3 may play a negative immunoregulatory role in the development of uveitis.

Objective:To investigate the intervention effect of dance therapy on the psychological symptoms and psychological craving in methamphetamine-dependent women.Methods:A total of 60 methamphetamine de-pendents in a women's drug rehabilitation center were divided into intervention group and control group(1 person dropped out).The intervention group was trained for 8 dance movements,during which the control group did not in-tervene.The Zhang Tuoji and Chen Huichang's Temperament Scale,Symptom Self-Rating Scale(SCL-90)and Amphetamine Craving Scale(DSQ)were used to evaluate the temperament type,psychological symptoms and psy-chological craving.Results:The differences of SCL-90 depression and anxiety scores(post-intervention score-base-line score)and DSQ total scores were higher in the intervention group than in the control group(Ps＜0.05).The choleric temperament scores were negatively correlated with the differences of DSQ total scores(r=-0.45,P＜0.05),and the melancholic temperament scores were positively correlated with the differences of SCL-90 hostility dimension scores(r=0.41,P＜0.05).Conclusion:Dance therapy could improve the psychological symptoms and psychological craving of women dependent on methamphetamine,with varying effects across different temperament types.

Objective:To investigate the current situation of knowledge, attitude and practice of medical personnel in areas with high incidence of fever with thrombocytopenia syndrome (SFTS) in Anhui Province, in order to provide a scientific basis for conducting systematic training for medical personnel.Methods:From July to August 2024, a multi-stage random sampling method was used to select medical personnel from village, township, county, and city level medical institutions in high incidence areas of SFTS in Anhui Province (Hefei City, Liu'an City, Chuzhou City, Xuancheng City) for an online questionnaire survey on their knowledge, attitude, and practice status. The survey included demographic data, knowledge, attitude, and practice related to SFTS, and a binary logistic regression model was used to analyze the influencing factors of SFTS knowledge qualification rate.Results:A total of 2 718 valid questionnaires were collected, with an effective response rate of 99.60% (2 718/2 729). Among them, 1 384 were males, accounting for 50.92%. The majority were medical personnel aged 41 to 50 years old, with undergraduate degrees, junior professional titles, working in township health centers or community health service centers, as clinical physicians, and with a working experience of no more than 10 years. They accounted for 31.97% (869/2 718), 50.48% (1 372/2 718), 35.54% (966/2 718), 38.52% (1 047/2 718), 62.33% (1 694/2 718), and 30.61% (832/2 718), respectively. The overall correct rates of medical personnel's relevant knowledge, attitude and practice were 77.52% (31 605/40 770), 94.53% (12 847/13 590) and 89.73% (12 194/13 590), respectively. There were statistically significant differences in the knowledge qualification of medical personnel of different genders, ages, education levels, professional titles, hospital levels, job positions, and years of work experience ( P < 0.05). The results of binary logistic regression analysis showed that professional title, hospital level, work position, and work experience were the influencing factors of knowledge qualification rate ( P < 0.05). Conclusions:Medical personnel have a relatively positive attitude and high level of practice towards SFTS, but their knowledge level still needs to be improved. It is recommended to provide targeted knowledge training for medical personnel in different positions to promote early detection, diagnosis, and treatment of SFTS.
