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.

Objective To understand the antibody levels of diphtheria and tetanus among healthy population in Shanghai Pudong New Area, and to provide a scientific basis for improving the vaccine immunization strategy. Methods Random sampling was used to select healthy people of all ages in 16 communities in Shanghai Pudong New Area from 2018 to 2024, and serum samples were collected and tested for serum anti-diphtheria and tetanus toxin IgG antibodies by enzyme-linked immunosorbent assay (ELISA) method to analyze the antibody positivity rate (≥0.1 IU/ml) and the geometric mean concentration (GMC) of antibodies. Results A total of 3 312 serum samples were included, with a male-to-female ratio of 0.76:1, and 53.77% were local residents. The seropositivity rates and geometric mean concentrations (GMC) of both diphtheria and tetanus antibodies generally declined with increasing age, but exhibited a transient rebound in the 7y-. A total of 1 175 individuals (35.48%) were seropositive for diphtheria, with a GMC of 0.054 IU/mL. For tetanus, 988 individuals (29.83%) were seropositive, with a GMC of 0.033 IU/mL. Significant differences in seropositivity rates (χ²_diphtheria=950.005,χ²_tetanus=1 324.393) and GMC (H_diphtheria=1027.160,H_tetanus=1 142.007) were observed among different age groups (P<0.001). Significant differences in seropositivity rates (χ²_diphtheria=950.005,χ²_tetanus=1324.393) and GMC (H_diphtheria=1027.160,H_tetanus=1142.007) were also found across different years (P<0.001). Conclusion The prevalence of diphtheria and tetanus antibodies in the healthy population of Pudong New Area is relatively low, particularly among adults over 20 years of age with inadequate immunization. This underscores the need to reinforce the National Immunization Program (NIP) vaccine specifications for children under 6 years of age and implement an immunization strategy for adolescents or adults against diphtheria and tetanus.

The contents of the female inguinal hernia include abdominal organs such as ovaries and fallopian tubes, and most of these are the result of sliding hernias. However, it is worth noting for surgeons specialized in hernia and abdominal wall surgery that there is a rare clinical diagnosis of hernia uterine inguinale, which is commonly seen in the Müllerian anomaly. Combined with relevant research progress at home and abroad, as well as the clinical experience in the diagnosis and treatment of patients with inguinal uterine hernia caused by Müllerian duct anomaly, the authors systematically introduce the clinical manifes-tations, key diagnosis and treatment points of female Müllerian duct anomaly in the inguinal region.

Objective:To analyze the clinical effect of XinjiaHuanglong Decoction add and subtract combined with auricular point sticking on delirium after hip fracture in elderly patients.Methods:Select 80 elderly patients with postoperative delirium after hip fracture admitted to our hospital from January 2022 to June 2024,and divide them into a matched group and an observation group,with 40 cases in each group.The matched group was treated with olanzapine,and the observation group was treated with XinjiaHuanglong Decoction add and subtract combined with auricular point sticking.Inflammatory response indexes(IL-6,TNF-α,hs-CRP)and stress response indexes(dopamine(DA),5-hydroxytryptamine(5-HT)were detected before and Post-treatment in both groups.Compare the Delirium Rating Scale 98(DRS-R-98)scores,Mini Mental State Examination(MMSE)scores,and duration of delirium between two groups before and Post-treatment,comprehensively evaluate the efficacy,and record the occurrence of adverse reactions.Results:Post-treatment,the DRS-R-98 score in the observation group was lower than that in the matched group,and the MMSE score was higher than that in the matched group(P＜0.05);The duration of delirium in the observation group was shorter than that in the matched group,and the overall effective rate was higher than that in the matched group(P＜0.05).The levels of inflammatory response indicators in the observation group were lower than those in the matched group Post-treatment(P＜0.05);The level of stress response indicators in the observation group was lower than that in the matched group Post-treatment(P＜0.05);There was no difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:XinjiaHuanglong Decoction add and subtract combined with auricular point sticking has a certain effect on improving delirium after hip fracture in the elderly,and can shorten the duration of delirium,which may be related to reducing inflammation and stress response,and it is safe and worthy of clinical application.

Objective To investigate the effect of Eriodictyol(ERI)on the development of metabolic dysfunction-associated steatotic liver disease by regulating the expression of ubiquitin A 52(UBA52)at both in vivo and in vitro levels.Methods A mouse metabolic dysfunction-associated steatotic liver disease model was established using a high-fat diet induction.The mice were randomly separated into the normal control group(normal group),the model group,the low-dose ERI group(ERI-L group,50 mg/kg ERI)and the high-dose ERI group(ERI-H group,100 mg/kg ERI),with 12 mice in each group.Oil red O staining was applied to observe lipid deposition in mouse liver tissue.HE staining was applied to observe pathological changes in mouse liver tissue.ELISA method was applied to detect serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC)and triglycerides(TG)in mice.The expression of UBA52 protein in liver was detected by Western blot assay.HepG2 cells were treated with 0.5 mmol/L oleic acid to induce an in vitro metabolic dysfunction-associated steatotic liver disease model.HepG2 cells were randomly divide into the control group,the oleic acid induced group,the low concentration ERI group(ERI low group,50 μmol/L ERI),the high concentration ERI group(ERI high group,100 μmol/L ERI),the high concentration ERI+si-NC group(ERI high+si-NC group,100 μmol/L ERI+transfected with si-NC)and the high concentration ERI+si-UBA52 group(ERI high+si-UBA52 group,100 μmol/L ERI+transfected with si-UBA52).Oil red O staining was applied to detect lipid deposition in HepG2 cells of each group.ELISA method was applied to detect the levels of TG,TC,SOD and MDA in HepG2 cells in each group.Immunoblotting was used to detect the expression levels of UBA52,p62 and autophagy related proteins in HepG2 cells.Results Compared with the normal group,serum levels of ALT,AST,LDL-C,TC,TG and the expression of UBA52 protein in liver tissue were increased in the model group(P＜0.05),and the lipid deposition in liver increased,pathological damage was severe,and the proportion of lipid deposition area and non-alcoholic fatty liver disease(NAFLD)activity score were also increased(P＜0.05).Changes in the corresponding indicators in the ERI-L group and the ERI-H group were opposite to those of the model group(P＜0.05),and the ERI-H group was even lower(P＜0.05).The lipid deposition in liver decreased and the pathological damage was alleviated.Compared with the control group,the levels of TG,TC,MDA,the proportion of lipid droplet area and the expression of UBA52 protein were increased in HepG2 cells of the oleic acid-induced group,while the levels of SOD,p62 and LC3Ⅱ/LC3Ⅰ decreased(P＜0.05).Changes in the corresponding indicators of the low-concentration ERI group and the high-concentration ERI group were opposite to those of the oleic acid-induced group(P＜0.05),and the therapeutic effect of ERI on metabolic dysfuntion-associated steatotic liver disease was enhanced after knocking down the expression of UBA52.Conclusion ERI may slow down the progression of metabolic dysfuntion-associated steatotic liver disease by down-regulating the expression of UBA52 at both in vivo and in vitro levels.

Objective To investigate the value of multimodal model integrating digital mammography(MG)and MRI radiomics features for preoperative prediction of lymphovascular invasion(LVI)status in breast cancer.Methods The clinical and imaging data from 336 patients with pathologically confirmed invasive breast cancer were retrospectively analyzed and randomly divided into a training group(235 cases)and a test group(101 cases)according to the ratio of 7∶3.Feature dimensionality reduction was carried out by Pearson correlation analysis followed by least absolute shrinkage and selection operator(LASSO)regression.Radiomics models were constructed based on MG craniocaudal(CC),dynamic contrast enhancement(DCE),T2 WI,and integrated MRI sequences;a multimodal model was further developed by incorporating clinical high-risk factors.The predictive efficiency of each model was evaluated by plotting receiver operating characteristic(ROC)curve.Results The ROC curve analysis showed that the multimodal model performed the best predictive efficiency,with area under the curve(AUC)of 0.989 and 0.861,accuracy of 0.949 and 0.782,sensitivity of 0.923 and 0.828,and specificity of 0.962 and 0.764 in the training group and test group respectively.Conclusion The multimodal model,integrating MG and MRI radiomics features,show optimal performance and can be served as a preoperative prediction of LVI status in breast cancer.

Objective:To investigate the predictive value of serum cholinesterase(CHE)and soluble growth stimula-tion gene 2 protein(sST2)for short-term death in patients with myocardial infarction and heart failure.Methods:A total of 100 patients with myocardial infarction and heart failure admitted in Nanjing Benq Hospital between March 2021 and March 2023 were screened.After 6-month follow-up,patients were grouped according to pres-ence of death.Multivariate Cox regression was used to analyze the factors associated with death during 6-month follow-up in patients with myocardial infarction and heart failure.The predictive value of CHE,sST2 and their combined detection for short-term death in patients with myocardial infarction and heart failure was analyzed by receiver operating characteristic(ROC)curve.Kaplan-Meier survival curve was used to compare short-term sur-vival rate between myocardial infarction and heart failure patients with different CHE and sST2 levels.Results:During 6-month follow-up,46 cases died.Compared to those in survival group,patients in death group had sig-nificant higher heart rate(HR)[(82.20±8.09)beats/min vs.(71.54±6.97)beats/min],mean arterial pressure(MAP)[(126.58±5.38)mmHg vs.(104.79±4.94)mmHg]and sST2[(76.48±4.82)ng/ml vs.(40.62±4.96)ng/ml],and significant lower CHE[(3.47±0.26)IU/L vs.(5.07±0.80)IU/L](P＜0.001 all).Multivariate Cox regression showed that HR(HR 1.046,95％CI 1.002～1.092,P=0.040),MAP(HR 1.988,95％CI 1.298～2.455,P＜0.001),and sST2(HR 1.068,95％CI 1.014～1.125,P=0.013)were independent risk factors for short-term death in patients with myocardial infarction and heart failure,while CHE was its independent protec-tive factor(HR=0.252,95％CI 0.145～0.561,P=0.023).ROC curve analysis indicated that the area under the curve(AUC)of CHE,sST2 and their combination for diagnosing short-term death in patients with myocardial in-farction and heart failure was 0.609(95％0.504～0.707),0.630(95％0.525～0.726)and 0.939(95％0.871～0.977)respectively,and the diagnostic efficacy of combined detection was significantly higher than CHE and sST2 alone(Z=5.814,5.524,P＜0.001 all).Kaplan-Meier survival curve showed that the survival rate of patients with low CHE level was significantly lower than that of patients with high CHE level,and the survival rate of pa-tients with high sST2 level was significantly lower than that of patients with low sST2 level(Log-rank x2=2.415,2.354,P＜0.001 all).Conclusion:CHE and sST2 were independent influencing factors for death during 6-month follow-up in patients with myocardial infarction and heart failure;their combined detection had good predictive value for short-term death in these patients.

Objectives:To investigate the predictive value of Murray's law-based quantitative flow ratio(μQFR)in side branches for long-term clinical prognosis in patients with non-left main bifurcation lesions who underwent simple main branch stenting,and to provide a potential functional assessment standard for intervention decision-making on coronary bifurcation lesions.Methods:A retrospective analysis was conducted in 408 patients with non-left main bifurcation lesions who underwent simple main branch stenting at Lianyungang First People's Hospital and Nanjing First Hospital between July 2018 and January 2021.The study utilized third-generation QFR software to analyze pre-and post-procedure anatomical and functional parameters of the target lesion's main branch and key branches.The primary endpoint was target vessel failure(TVF)events during the 3-year follow-up.Patients were stratified into TVF and non-TVF groups.Baseline characteristics,procedural data,and pre-/post-procedural parameters of target vessels were compared between groups.Multivariable Cox regression was performed to identify predictors of TVF.Diagnostic efficacy of predictors was evaluated using area under the receiver operating characteristic(ROC)curve(AUC)with DeLong's method for comparison.Patients were dichotomized based on the optimal cutoffof post-procedural side branch μQFR,with TVF incidence rates compared via Cox regression and Kaplan-Meier analysis.Results:During 3-year follow-up,54 patients(13.2%)experienced TVF(TVF group),data were compared with 354 patients(86.76%)without TVF(non-TVF group).The TVF group showed higher post-procedural side branch diameter stenosis([32.93±17.80]%vs.[22.62±11.96]%,P<0.001)and lower μQFR(0.80±0.10 vs.0.89±0.07,P<0.001).Multivariate Cox regression identified higher post-procedural side branch μQFR as an independent protective factor against 3-year TVF(per 0.01 increase:HR=0.903,95%CI:0.850-0.959,P<0.001).ROC curves indicated that post-procedural side branch μQFR had moderate diagnostic efficacy for predicting 3-year TVF(AUC=0.769,95%CI:0.678-0.861,P<0.001),with a significantly higher AUC value than post-operative side branch area stenosis and minimal lumen diameter(both P<0.001),the optimal cutoffvalue was 0.84.Multivariate Cox regression and Kaplan-Meier survival analysis revealed markedly higher 3-year TVF rates in patients with μQFR≤0.84 compared to patients with μQFR>0.84(HR=4.007,95%CI:2.342-6.855,P<0.001;28.3%vs.7.9%,log-rank P<0.001).Conclusions:For patients with bifurcation lesions not involving the left main,the immediate post-procedural side branch μQFR could better predict 3-year TVF than anatomical indices.Maintaining post-stenting side branch μQFR>0.84 may optimize clinical outcomes when using a single-stent strategy.

Objective To investigate the relationship between the expression levels of serum integrin αMβ2(ITG αMβ2)and gasdermin D(GSDMD)in patients with severe acute pancreatitis(SAP)complicated with acute respiratory distress syndrome(ARDS)and the severity of the disease and its value in predicting prognosis.Methods A total of 147 patients with SAP complicated with ARDS(ARDS group)admitted to the Department of Intensive Care Medicine of the Southwest Jiaotong University Affiliated Hospital(Chengdu Third People's Hospital)from August 2021 to October 2023 were selected.According to the oxygenation index(OI),they were divided into mild group(n=35),moderate group(n=46)and severe group(n=66).According to the 28-day prognosis,they were divided into death group(n=77)and survival group(n=70).Another 147 SAP patients without ARDS at the same time period were selected(non-ARDS group).The expression levels of serum ITG αMβ2 and GSDMD were detected by enzyme-linked immunosorbent assay.Spearman method was used to analyze the correlation between serum ITG αMβ2,GSDMD expression levels and OI in patients with SAP complicated with ARDS.Multivariate Logistic regression was used to analyze the factors of death in patients with SAP complicated with ARDS.Receiver operating characteristic(ROC)curve was used to analyze the value of serum ITG αMβ2,GSDMD expression levels in evaluating the death of patients with SAP complicated with ARDS.Results Compared with the non-ARDS group,the expression levels of serum ITG αMβ2(31.95±8.17 ng/L vs 53.33±12.22 ng/L)and GSDMD(2.25±0.55 ng/ml vs 4.39±1.18 ng/ml)in the ARDS group were increased,and the differences were statistically significant(t=17.637,19.899,all P<0.05).The expression levels of serum ITG αMβ2 and GSDMD in mild group,moderate group and severe group increased in turn,and the differences were statistically significant(F=163.069,194.028,all P<0.05).The expression levels of serum ITG αMβ2 and GSDMD were negatively correlated with OI in patients with SAP complicated with ARDS(r=-0.787,-0.778,all P<0.05).The 28-day mortality rate of 147 SAP patients with ARDS was 52.38%(77/147).Compared with the survival group,the expression levels of serum ITG αMβ2(46.96±10.28 ng/L vs 59.11±10.94 ng/L)and GSDMD(3.74±0.98 ng/ml vs 4.98±1.04 ng/ml)in the death group were increased,and the differences were statistically significant(t=6.920,7.415,all P<0.05).The number of extrapulmonary organ failure≥2,prolonged mechanical ventilation time,increased acute physiological and chronic health assessment II score,and increased ITG αMβ2.and GSDMD were independent risk factors for death in SAP patients complicated with ARDS(Wald χ2=4.297～13.536,all P<0.05),and increased OI was an independent protective factor(Wald χ2=8.346,P<0.05).The combined evaluation AUC of serum ITG αMβ2 and GSDMD expression levels results in a larger area under the curve(AUC)for mortality in SAP patients with ARDS compared to the individual evaluation of SAP complicated with ARDS,which was greater than serum ITG αMβ2 and GSDMD expression levels alone,and the differenes were statistically significant(Z=3.517,3.430,all P<0.05).Conclusion The increase of serum ITG αMβ2 and GSDMD expression levels is related to the progression and poor prognosis of patients with SAP complicated with ARDS.The combined monitoring of serum ITG αMβ2 and GSDMD expression levels has a high evaluation value for the risk of death in patients with SAP complicated with ARDS.
