To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine. For each research direction，key focus areas，expected objectives，and clinical value were further refined，along with the establishment of a scientifically sound priority funding level evaluation system. Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Objective To compare the effectiveness between ultrasound-guided paravertebral block(PVB)and general anesthesia in percutaneous nephrolithotomy(PCNL).Methods Clinical data of 284 patients who underwent PCNL in our hospital from January 2023 to March 2024 were collected.These were 78 cases of PVB(PVB group)and 206 cases of general anesthesia(general anesthesia group).A total of 61 cases in each of the two groups were matched with propensity score,and the operative time,intraoperative fluid infusion volume,postoperative haemoglobin changes,postoperative visual analogue scale(VAS),hospital stay,hospital costs,and incidence of postoperative complications were compared.Results The operations were completed in both groups of patients successfully,with stable vital signs during the operation and no intraoperative anesthetic complications such as bradycardia,respiratory depression,or hypotension.There were significant differences between the two groups in heart rate(HR)before the start of surgery[(66.5±10.4)beats/min vs.(77.5±11.7)beats/min,t=-5.471,P=0.000],HR at the end of surgery[(60.5±8.4)beats/min vs.(71.0±12.3)beats/min,t=-5.472,P=0.000],mean arterial pressure(MAP)before the start of surgery[(97.2±11.9)mm Hg vs.(103.1±12.3)mm Hg,t=-2.694,P=0.008],MAP at the end of surgery[(85.2±8.8)mm Hg vs.(94.3±11.6)mm Hg,t=-4.892,P=0.000],pulse oxygen saturation(SpO2)before the start of surgery[(99.0±1.1)％vs.(99.6±0.6)％,t=-3.347,P=0.001]and SpO2 at the end of surgery[(99.2±1.1)％vs.(99.8±0.4)％,t=-4.122,P=0.000].The operative time was significantly shorter in the PVB group than that in the general anesthesia group[55.0(41.5,75.5)min vs.95.0(65.0,130.0)min,Z=-5.173,P=0.000].The postoperative haemoglobin changes[5(2,11)g/L vs.8(4,11)g/L,Z=-2.099,P=0.036],postoperative VAS score[1(1,1)points vs.1(1,2)points,Z=-3.342,P=0.001],postoperative hospital stay[3(2,3)dvs.4(3,6)d,Z=-6.016,P=0.000]and hospital costs[(14 499.4±2141.0)yuan vs.(19 634.2±3846.8)yuan,t=-9.109,P=0.000]were statistically lower in the PVB group than those in the general anesthesia group.Comparison of intraoperative fluid infusion volume[600(600,600)ml vs.600(600,1100)ml,Z=-1.800,P=0.072],postoperative venting time[1(1,1)d vs.1(1,1)d,Z=-1.045,P=0.296],and phase Ⅰ stone removal rate[88.5％(54/61)vs.82.0％(50/61),x2=1.043,P=0.307]showed no significant differences between the two groups.The incidence of postoperative complications in the PVB group was significantly lower than that in the general anesthesia group[6.6％(4/61)vs.19.7％(12/61),x2=4.604,P=0.032].Conclusion Ultrasound-guided PVB in PCNL maintains stable intraoperative vital signs,reduces operative time and bleeding,alleviates postoperative pain,reduces postoperative complications and postoperative hospital stay,and saves medical costs,having a good safety and efficacy.

Objective:This study aims to investigate the alterations in m 6A methylation associated with age-related idiopathic pulmonary fibrosis(IPF). Methods:By collecting peripheral blood samples from IPF patients, we investigated the changes in m6A modification levels of total RNA and key regulatory factors in elderly IPF patients.Then, the pulmonary fibrosis models of young and old mice were constructed for verification.A total of 10 IPF patients and 10 healthy controls were selected for this study.The m 6A methylation quantitative kit was employed to assess the m 6A modification levels of total RNA.The expression levels of key m 6A methylation regulators, METTL3, METTL14, and FTO, were quantified using qRT-PCR.Additionally, thirty-two healthy male C57BL/6 mice, comprising 16 mice aged 10-12 weeks and 16 mice aged 6-7 months, were divided into four groups: young control(A), young pulmonary fibrosis(B), aged control(C), and aged pulmonary fibrosis(D), with 8 mice in each group.Mice in groups B and D were intratracheally administered bleomycin to establish a pulmonary fibrosis model, while those in groups A and C received normal saline.Twenty-eight days post-model establishment, the mice were euthanized, and lung tissues were collected for analysis.Histological evaluations were performed using hematoxylin and eosin(HE)staining, Masson staining, hydroxyproline content determination, and immunohistochemistry to assess the extent of pulmonary fibrosis.The m 6A methylation quantification kit was also utilized to measure the m 6A modification levels of total RNA in lung tissue.Furthermore, the mRNA and protein expression levels of the methyltransferase METTL3 were assessed by qRT-PCR and Western blot experiments. Results:The level of m 6A modification was significantly elevated in the aged IPF patient group(0.36±0.03)compared to the control group t=4.882( P<0.05).Furthermore, the expression of METTL3 was markedly higher in the aged IPF patients( t=6.082), while the expression of METTL14 was significantly lower t=17.58( P<0.05).In contrast, the expression level of FTO did not exhibit a significant difference.It is hypothesized that the increased m 6A modification of total RNA in aged IPF patients is closely associated with METTL3.Furthermore, the degree of lung fibrosis in aged mice was more severe than that in young mice.Immunohistochemistry results indicated that TGF-β1 expression was elevated in the lung fibrosis group, with higher levels observed in group D compared to group B( t=5.891, P<0.05), and in group C compared to group A t=4.135( P<0.05).The percentage of positive area for α-SMA was significantly greater in the lung fibrosis mouse model than in the control group t=20.08( P<0.05).The level of m 6A modification was increased in both lung fibrosis groups relative to the normal control group( P<0.05), although no significant difference was found between group D and group B. Overall, METTL3 mRNA and protein expression were upregulated in the lung fibrosis group, with expression in group D being lower than in group B( P<0.05). Conclusions:The level of m 6A modification is elevated in pulmonary fibrosis, and the expression of METTL3 is upregulated in this condition.The downregulation of METTL3 may be associated with the extent of aging, which subsequently exacerbates the progression of pulmonary fibrosis.

Objective:To analyze the pathogen spectrum and epidemiological characteristics of acute respiratory infections in Yantai from 2024 to 2025.Methods:Influenza-like illness（ILI）and severe acute respiratory infection（SARI）patients were enrolled from the national sentinel hospitals for acute respiratory infectious diseases in Yantai between January 2024 and April 2025. Oropharyngeal swab samples were collected and 16 common respiratory pathogens were tested using real-time quantitative PCR. Descriptive epidemiological methods were used to analyze the detection results.Results:A total of 1 499 cases were included in the study，including 1 070 ILI cases and 429 SARI cases. The overall positive rate of respiratory pathogens was 52.57%（788/1 499）. All of the 16 targeted respiratory pathogens were detected，with influenza virus A（FluA），SARS-CoV-2， Haemophilus influenzae（ Hi），and human adenovirus（HAdV）being the predominant pathogens. The co-infection rate was 6.27%（94/1 499），with FluA combined with Hi infection being the predominant type. Statistically significant differences in the positive rates of influenza B virus and SARS-CoV-2 were observed between male and female patients（both P<0.05）. The overall positive rates varied significantly across different age groups（ P<0.001），with the highest rate（64.62%，84/130）observed in the 4-14 year age group. The overall positive rates also varied significantly among different months（ P<0.001），with the highest rate in December（69.93%，107/153）. The overall positive rate was 57.48%（615/1 070）in ILI cases and 40.33%（173/429）in SARI cases，with statistically significant difference between the two groups（ P<0.001）. Influenza viruses and SARS-CoV-2 were the predominant pathogens in ILI cases，whereas HAdV and Mycoplasma pneumoniae were more common in SARI cases. Conclusions:FluA，SARS-CoV-2， Hi，and HAdV are the predominant pathogens causing acute respiratory infections in Yantai from January 2024 to April 2025. The positive rates of respiratory pathogens varies across different gender and age groups，and shows distinct seasonal patterns. There are significant differences in pathogen spectra between ILI and SARI cases.

Objective:To investigate the correlation between plasma Dickkopf-1 (DKK1) and post-stroke cognitive impairment (PSCI) in patients with acute ischemic stroke.Methods:Consecutive patients with first-ever acute ischemic stroke admitted to the Department of Neurology, Nanjing Jiangbei Hospital from March 2023 to February 2024 were included prospectively. Enzyme-linked immunosorbent assay was used to detect plasma DKK1 within 24 hours of onset. The Montreal Cognitive Assessment Scale was used to evaluate cognitive function at 3 months after onset. A score ≤22 was defined as PSCI. Multivariate logistic regression analysis was used to determine the correlation between DKK1 and PSCI. The relationship between DKK1 and PSCI risks was evaluated through restrictive cubic spline analysis. Results:A total of 205 patients with acute ischemic stroke were enrolled, including 106 males (51.7%), aged 67.0±9.4 years; 61 patients (29.8%) experienced PSCI. Multivariate logistic regression analysis showed that after adjusting for age, gender, education level, and other confounding factors, there was a significant independent correlation between higher plasma DKK1 and PSCI (odds ratio 1.778, 95% confidence interval 1.313-2.408; P=0.001). Subgroup analysis showed that age, gender, etiological classification of stroke, and education level had no significant effect on the above correlation. Restrictive cubic spline analysis showed plasma DKK1 had a linear relationship with the risk of PSCI ( P=0.003). Conclusion:Higher plasma DKK1 level is significantly correlated with PSCI in patients with acute ischemic stroke at 90 days after onset.

Objectives:To investigate the predictive factors of stroke associated-pneumonia (SAP) in patients with acute stroke, develop nomogram and neural network prediction models and verify their predictive performance.Methods:Patients with acute stroke admitted to the First Affiliated Hospital of Kunming Medical University and Zhenxiong County People's Hospital were included retrospectively. Multivariate logistic regression analysis was used to determine the independent predictive factors of SAP, and develop nomogram and neural network prediction models. Receiver operating characteristic curve (ROC) curves were used to validate and compare the predictive performances. Results:A total of 450 patients with acute stroke were enrolled, including 286 males (63.6%), aged 64.28±13.24 years; 344 patientss (76.4%) had ischemic stroke and 106 (23.6%) had hemorrhagic stroke; 128 patients (28.4%) experienced SAP. According to the random number method, they were divided into a modeling cohort ( n=300) and a validation cohort ( n=150). Multivariate logistic regression analysis in the modeling cohort showed that a higher baseline National Institutes of Health Stroke Scale (NIHSS) score, gastric tube placement, use of proton pump inhibitors, heart failure, and higher neutrophil/lymphocyte ratio (NLR) were the independent predictive factors of SAP. ROC curve analysis showed that the area under the ROC curve of the nomogram model for predicting SAP in the modeling cohort and validation cohort was 0.841 (95% confidence interval [ CI] 0.795-0.880) and 0.863 (95% CI 0.798-0.914), respectively. The sensitivity for predicting SAP were 75.00% and 70.45%, respectively, and the specificity was 81.94% and 92.45%, respectively. The area under the ROC curve of the neural network model for predicting SAP in the modeling cohort and validation cohort was 0.847 (95% CI 0.802-0.866) and 0.862 (95% CI 0.796-0.913), respectively. The sensitivity for predicting SAP were 76.19% and 72.73%, and the specificity was 79.17% and 89.62%, respectively. Conclusions:Higher NIHSS score, gastric tube placement, use of proton pump inhibitors, heart failure, and higher NLR are the independent risk factors for SAP in patients with acute stroke. The nomogram and neural network prediction model developed using the above risk factors have higher predictive value for SAP.
