ObjectiveTo explore the mechanism of Xianfang Huomingyin （XFHMY） in the treatment of type Ⅲ prostatitis （CP/CPPS） through network pharmacology， molecular docking， and animal experiments. MethodsThe traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the Swiss Target Prediction database were used to screen and sort out the active ingredients and corresponding targets of XFHMY. The potential therapeutic targets of CP/CPPS were collected from online databases， such as the Online Mendelian Inheritance in Man （OMIM）， GeneCards， and DisGeNET. The potential core targets of XFHMY for treating CP/CPPS were further screened by constructing a protein-protein interaction （PPI） network and performing topological analysis. Meanwhile， the DAVID database was chosen to perform enrichment analysis on the intersection targets. On this basis， the AutoDock software was used for molecular docking， and the data was subsequently imported into the GraphPad Prism 8 software to generate a heat map. SD rats were divided into seven groups： A blank group， a sham operation group， a model group， low-， medium-， and high-dose XFHMY groups （3.645， 7.29， 14.58 g·kg^-1）， and a tamsulosin hydrochloride group （0.018 mg·kg^-1）. Hematoxylin-eosin （HE） staining was used to evaluate the pathological changes in prostate tissue. The inflammatory factor indicators of rats in each group were detected via enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （Real-time PCR） and Western blot were used to evaluate the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， and nuclear transcription factor-κB （NF-κB） p65 in prostate tissue. ResultsThe HE staining showed no significant signs of inflammatory cell infiltration in the prostate of the sham operation group compared to the blank group， while the model group had significantly inflammatory cell infiltration. The ELISA results showed that compared to the blank group， TNF-α， IL-1β， and COX-2 in the sham operation group had no significant differences. However， they were significantly higher in the model group （P<0.01）， indicating successful CP/CPPS modeling in rats. Compared with the model group， the low-，medium-and high-dose XFHMY group and the tamsulosin hydrochloride group showed significant decreases in TNF-α， IL-1β， and COX-2 （P<0.05，P<0.01）. The Real-time PCR analysis revealed that compared to the model group， the low-dose XFHMY group had reduced Akt and NF-κB p65 mRNA expression（P<0.05，P<0.01）. In the medium-and high-dose XFHMY group and tamsulosin hydrochloride group， PI3K， Akt， and NF-κB p65 mRNA levels decreased significantly（P<0.05，P<0.01）. Western blot analysis showed that compared to the model group， the low-dose XFHMY group had lower p-NF-κB p65/NF-κB p65 （P<0.05）. The medium- and high-dose XFHMY group and the tamsulosin hydrochloride group showed significant decreases in p-PI3K/PI3K， p-Akt-ser473/Akt， p-Akt-thr308/Akt， and p-NF-κB p65/NF-κB p65 （P<0.01）. ConclusionXFHMY may exert therapeutic efficacy on CP/CPPS by inhibiting the PI3K/Akt/NF-κB signaling pathway and reducing inflammatory responses. Additionally， NF-κB activation may be related to the activation of ser473 and thr308 sites.

Objective To analyze the clinical and imaging features of primary anorectal malignant melanoma (ARMM) and to improve the level of its early diagnosis and clinical management. Methods A retrospective analysis was performed on the clinical data, multimodal imaging features, treatment methods, pathological results, and follow-up information of 31 patients with pathologically diagnosed ARMM at Zhongshan Hospital, Fudan University from December 2016 to October 2025. Results Among the 31 patients, there were 11 males and 20 females, with age of 65 (55, 71) years. Twenty-one patients presented with hematochezia as the initial symptom (67.7%), and four asymptomatic patients were detected incidentally by physical examination. All the patients showed negative alpha-fetoprotein, carcinoembryonic antigen, and carbohydrate antigen 19-9. All 31 cases were solitary ARMM, of which 14 (45.2%) were located in the anorectal region. CT was characterized by polypoid or fungating masses, absence of intestinal obstruction, moderate to marked enhancement; MRI was characterized by specific T₁WI hyperintensity and restricted diffusion; PET/CT is characterized by high metabolism. According to Ballantyne staging, 10 cases of stage Ⅰ, 11 cases of stage Ⅱ and 10 cases of stage Ⅲ were found. Endoscopic resection was performed in 1 patient, transanal resection in 2 patients, and abdominoperineal resection (Miles operation) with routine lymph node dissection in 17 patients. The positive rates of S-100, HMB-45 and Melan-A in 20 surgical patients were 100%, 95% and 100%, respectively, with a median Ki-67 proliferation index of 65%. Median postoperative follow-up duration of surgical patients was 34.5 (2−90) months. During follow-up, 8 patients (40%) developed recurrence and/or metastasis (median time was 11 months after surgery), with the liver and lungs being the most common metastatic sites. Conclusions Primary ARMM predominantly occurs in middle-aged and elderly women, hematochezia is the most common initial symptom. Diagnostic efficacy can be improved by combining characteristic imaging manifestations and immunohistochemical findings. ARMM is a highly malignant tumor with an overall poor prognosis, surgery remains the main therapeutic approach.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective: To analyze the serotypes and drug resistance of Salmonella isolated from food-borne disease surveillance samples in Longwan District, Wenzhou City, Zhejiang Province, so as to provide evidence for the prevention and treatment of Salmonella infection. Methods: Salmonella strains isolated from feces or anal swabs of patients with foodborne diarrhea in Longwan District People's Hospital from 2018 to 2024 were collected. After re-identification, slide agglutination test was used to identify serotypes. The drug susceptibility test of live Salmonella strains was performed using the broth microdilution method, and the resistance patterns were analyzed. Results: A total of 2 293 samples were collected, and 186 strains of Salmonella were isolated, with a detection rate of 8.11%. The detection rate was higher from May to October. A total of 28 Salmonella serotypes were identified, with S. typhimurium (72 isolates, 38.71%), S. enteritidis (31 isolates, 16.67%), and S. London (30 isolates, 16.13%) being dominant. Among the 121 Salmonella live strains, 20 strains were susceptible to 14 antibacterial drugs. A total of 101 strains were resistant to antibacterial drugs, and the drug resistance rate was 1.65%-67.77%, with the drug resistance rate of ampicillin being the highest, and the drug resistance rate of imipenem was the lowest. S. typhimurium had the highest resistance rate to tetracycline (78.26%). S. enteritidis had the highest resistance rate to ampicillin (100.00%). S. London had the highest resistance rate to tetracycline (66.67%). Fifty-five types of drug resistance patterns were detected, showing a number of drug resistance of 1-10, of which 76 strains were multi-drug resistant, accounting for 75.25%. The predominant multidrug resistance patterns were ampicillin/sulbactam-cefazolin-ampicillin-nalidixic acid (10.53%), tetracycline-ampicillin-nalidixic acid (9.21%), and ampicillin/sulbactam-ampicillin-nalidixic acid (7.89%). Conclusions Salmonella strains isolated from foodborne diseases in Longwan District were mainly detected in summer and autumn. S. typhimurium, S. enteritidis, and S. London were the predominant serotypes. The drug resistance of Salmonella to different antibacterial drugs was different, and the drug resistance spectrum showed diversity.

Objective:To investigate the influencing factors for dysphagia in the elderly,to construct a predictive model for dysphagia,and to provide a theoretical basis for clinical practice.Methods:In this case-control study,the patients with dysphagia who attended Department of Geriatrics in the first affiliated hospital of Chongqing Medical University from March 2016 to June 2023 were enrolled as case group,and the patients without dysphagia who attended the same department during the same period of time were enrolled as con-trol group.The correlation analysis,least absolute shrinkage and selection operator(LASSO)regression,and multivariate logistic re-gression analysis were used to investigate the influencing factors for dysphagia;the 10-fold cross-validation Extreme Gradient Boosting(XGBoost)model was used to predict dysphagia,and the SHapley additive exPlanations(SHAP)method was used for model visualiza-tion.Results:There were 1009 cases in the case group and 2125 cases in the control group.The correlation analysis and LASSO re-gression analysis identified 12 factors for the multivariate logistic re-gression analysis,and the results showed that sarcopenia,increasing age,children or caretakers as caregivers,frail health,poor oral health,poor self-care ability,depression,and cognitive impairment were risk factors for dysphagia(odds ratio[OR]>1,P<0.05),and fe-male sex and participation in community activities were protective factors against dysphagia(OR<1,P<0.05).The XGBoost model had a good predictive efficacy,with an accuracy rate of 0.795,a preci-sion rate of 0.711,a sensitivity of 0.613,a specificity of 0.881,an F1 value of 0.661,and an area under the ROC curve of 0.855.The SHAP plot showed that the top five important characteristics were caregiver,oral score,frail health condition,activities of daily living,and cognitive function.Conclusion:There are various influencing factors for dysphagia in the elderly,and the elderly patients with poor oral health,frailty,dependence on others for daily life,and cognitive impairment should be taken seriously in clinical practice.The XGBoost model has a good performance in predicting dysphagia in the elderly,which can provide a reference for clinical practice.

Objective To stratify the estrogen receptor(ER)positive while human epidermal growth factor receptor 2(HER2)negative breast cancer patients by the expression level of ER,providing new evidence for prognostic prediction and guiding precision endocrine therapy(ET)for those with different ER expression levels.Methods A retrospective cohort study was conducted on 1 962 ER-positive/HER2-negative breast cancer patients treated in our department from January 1,2013 to December 31,2018.X-tile was used to calculate the optimal cutoff point of ER expression level,and then based on the results,they were divided into low(1%～10%),moderate(11%～30%),and high expression(31%～100%)groups.After propensity score matching(PSM)was performed to balance baseline characteristics,their prognostic outcomes were compared and the responses to ET were analyzed in the groups.Cox proportional risk regression model was applied to analyze the prognostic factors,and subgroup analysis was further performed.Results After PAM,129(11.5%)were assigned into a low ER expression group,151(13.5%)and 840(75%)into moderate and high ER expression groups,respectively.Statistical differences were observed in disease-free survival(DFS)and overall survival(OS)among the 3 groups(P=8e-6,P=8e-14).In the low ER expression group,the patients treated with selective estrogen receptor modulators(SERMs)showed no significant differences in DFS and OS than those treated with aromatase inhibitors(AIs)(P>0.05).However,the patients from the moderate and high ER expression groups demonstrated significantly better DFS when treated with AI than with SERM(P=0.02,P=0.03).Multivariate analysis showed that compared with the moderate ER expression group,the high ER expression group exhibited significantly lower risk of disease recurrence/metastasis(HR=0.62,95%CI:0.43～0.88,P=0.009)and risk of death(HR=0.49,95%CI:0.26～0.93,P=0.03).Subgroup analysis revealed that when compared with the high ER expression group,the moderate ER expression group exhibited notably worse DFS in the following subgroups:oral SERM,non-breast-conserving surgery,lymph node metastasis,TNM stage Ⅱ,and chemotherapy,and shorter OS in the subgroups of oral SERM,non-breast-conserving surgery,lymph node metastasis,TNM stage Ⅱ subgroup,and chemotherapy.Conclusion Taking ER expression of 11%～30%as an independent stratification criterion can guide more accurate prognostic assessment and more rational ET selection in ER-positive/HER2-negative breast cancer patients.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Background and objective Lung cancer is the malignant tumor with the highest incidence rate and the heaviest disease burden in China.In recent years,lung cancer has shown a high incidence trend,seriously affecting the health of the population.In this paper,we analyze the characteristics of lung cancer incidence in 2019 and the trend of incidence rate from 2010-2019 in the tumor registration area of Gansu province,in order to provide a reference basis for the development of lung cancer prevention and control strategies in Gansu province.Methods By analyzing the cases of lung cancer incidence in the tumor registration area of Gansu province in 2019,we calculated the incidence rate,medium incidence rate,world in-cidence rate and other related indexes;we used Joinpoint to calculate the annual percentage change(APC)for trend analysis.Results In 2019,a total of 3757 new cases of lung cancer were reported in Gansu province,accounting for 14.96%of all new malignant tumors.The incidence rate,medium incidence rate and world incidence rate and world rate of lung cancer were 40.52/105,25.78/105,25.86/105;and the cumulative rate of 0-74 years old,and the truncation rate of 35-64 years old were 3.23%,40.03/105,respectively.The incidence of lung cancer rises with age,and is high in the age group of 40 years and above,and the incidence peaks in the male and female populations in the group of 75 years and above,and the group of 80 years and above,respectively.The crude incidence rate of lung cancer in the tumor registration area of Gansu province from 2010-2019 showed an overall increasing trend,and the rate of increase was relatively fast,with an APC 5.39%(P<0.05);Separately,accord-ing to gender,urban and rural areas,the incidence of lung cancer in all populations showed an increasing trend,and the APC of male,female,urban and rural populations were 4.98%,6.39%,6.26%,and 4.64%,respectively(all P<0.05).According to the trend analysis of lung cancer incidence rate by age group,only lung cancer incidence in the age group of 65 years and above increased at an annual average rate of 4.15%(P<0.05).Conclusion The incidence rate of lung cancer in the tumor registration area of Gansu province from 2010 to 2019 shows a rising trend year by year,and there are differences in the incidence of lung cancer in people of different genders,regions and age groups,so comprehensive prevention and control work should be carried out for the key populations of lung cancer incidence.

Objectives To investigate the relationship between self-reported occupational noise exposure and levels of plasma inflammatory cytokines in asthmatic patients. Methods A total of 910 adult asthmatic patients were selected as the study subjects, and their occupational noise exposure history and other related information were collected. The peripheral blood samples were collected from the patients, and the expression levels of plasma soluble CD14 (sCD14), complement factor D (CFD), Eotaxin-11 (CCL11), and IL-9 were determined. The relationship between self-reported occupational noise exposure and the expression levels of the four inflammatory cytokines in patients’ plasma were analyzed using multiple linear regression models. The interactions between confounding factors and self-reported occupational noise exposure were further analyzed by interaction analysis. Results The plasma CCL11, sCD14 and CFD expressions in asthmatic patients with self-reported occupational noise exposure were significantly higher than those in patients without the exposure (P<0.05). After adjusting for confounding factors, compared with patients reporting no occupational noise exposure, the plasma CFD expression was increased by 0.17 (95% CI: 0.02, 0.31) natural logarithm units in patients with self-reported occupational noise exposure. During remission, the levels of plasma CCL11 and sCD14 in asthmatic patients with self-reported occupational noise exposure were increased by 0.27 (95% CI: 0.05, 0.49) and 0.22 (95% CI: 0.02, 0.41) natural logarithm units, respectively, when compared with patients without the exposure. Interaction analysis showed that self-reported occupational noise exposure had significant multiplicative interaction with smoking or pet ownership on plasma CCL11 or CFD expressions in asthmatic patients (all P<0.05). Conclusion Self-reported occupational noise exposure is significantly associated with increased expression levels of plasma CFD, CCL11, and sCD14 in adult asthmatic patients.
