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.

Cardiac arrest is a major health event that poses a major threat to human life and health.Post-cardiac arrest brain injury is the main adverse prognostic factor and cause of death in patients who experience cardiac arrest.Currently,the therapeutic methods and effects are limited.In recent years,with the in-depth research on microbiota-gut-brain communication,it has been found that intestinal microbiota and their metabolites may play a role in the regulation of neuroinflammation in post-cardiac arrest brain injury.Short-chain fatty acids are the key substances in microbiota-gut-brain communication,and the mechanism involves immune,endocrine and neuroregulatory pathways.Supplementation of short-chain fatty acid-producing bacteria or short-chain fatty acids can improve intestinal flora disorder and reduce neuroinflammation after cardiopulmonary resuscitation.As a key mediator in microbial-gut-brain communication,short-chain fatty acids have great potential for the treatment of brain injury after cardiac arrest.This review explores the role and regulatory mechanism of microbiota-gut-brain communication in the neuroinflammation of brain injury after cardiopulmonary resuscitation through immune,endocrine and neuro-regulatory pathways,providing a new idea for the treatment of post-cardiac arrest brain injury.

Objective:To detect the expression of autophagy-related genes (ATGs) involved in the late stage of autophagy in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS), analyze the difference and explore its possible clinical significance.Methods:① Peripheral blood specimens and clinical data were collected from 90 AS patients (AS group) who attended the outpatient clinic of the Department of Rheumatology and Immunology of the Affiliated Hospital of North Sichuan Medical College from March 2022 to August 2023, among which 30 patients were treated with secukinumab monoclonal antibody for 24 weeks (the treatment group), and clinical data and peripheral blood specimens from 45 healthy individuals (the HC group) who had medical checkups in the Affiliated Hospital of Chuanbei Medical College during the same period were used as the control group. As the control group, the mRNA expression levels of six ATGs (ATG5, ATG7, LC3-Ⅱ, ATG4B, ATG2A, ATG10) involved in the late autophagy stage were detected in PBMCs of peripheral blood specimens by RT-qPCR, and were compared among different groups, and the measured data conformed to the normal distribution were analyzed using the paired t-test, and the abnormal distribution date were analyzed using the Wilcoxon signed-rank test. Wilcoxon signed-rank test was used for measurement data, and Spearman correlation analysis was used for correlation analysis. ② Receiver operating curve (ROC) was used to verify the difference in the expression of ATGs in the late stage of autophagy between AS group and HC group to evaluate its value in the diagnosis of AS and the inflammatory state of the disease. Results:① Compared with the HC group, ATG2A [2.00(1.10, 2.70)×10 -3, 7.50(4.60, 10.0)×10 -3, Z=-6.67, P<0.001], ATG5 [3.60 (2.30, 5.30)×10 -3, 7.20(5.50, 9.20)×10 -3, Z=-3.63, P=0.001], LC3Ⅱ[25.70(8.50, 35.00)×10 -3, 52.20(45.00, 69.10)×10 -3, Z=-5.87, P<0.001] and ATG7[5.50(3.20, 8.10)×10 -3, 8.30(5.20, 9.80)×10 -3, Z=-2.38, P=0.017] the mRNA expressions were significantly decreased in the AS group. ②ATG5 mRNA expression was negatively correlated with platelet count ( r=-0.35, P=0.008), LC3-Ⅱ was negatively correlated with estimated glomerular filtration rate ( r=-0.33, P=0.017), ATG7 was positively correlated with absolute basophil count ( r=0.33, P=0.011),ATG10 was negatively correlated with estimated glomerular filtration rate and C-reactive protein (CRP) was negatively correlated ( r=-0.30, P=0.032). ③ The area under the ROC curve (AUC) of ATG2A mRNA expression level for predicting AS was 0.910, and the sensitivity and specificity were 94.6% and 83.8% respectively. ④ After 24 weeks of treatment with secukinumab, the mRNA expression levels of ATG2A[2.00(1.20, 2.90)×10 -3, 4.90(0.10, 7.40)×10 -3, Z=-3.75, P<0.001] and LC3-Ⅱ[2.00(1.20, 2.90)×10 -3, 4.90(0.10, 7.40)×10 -3, Z=-3.75, P<0.001]were elevated in the AS patients. Conclusion:Late autophagy-related genes ATG2A, ATG5, LC3II, ATG7 may be involved in AS development.The AUC of ATG2A in AS is 0.91, suggesting that ATG2a is expected to be a biological indicator for early diagnosis of AS. Secukinumab may be involved in the regulation of autophagy by affecting the expression of late autophagy genes, but the specific mechanism needs to be further explored.

Secukinumab may be involved in the regulation of autophagy by affecting the expression of late autophagy genes, but the specific mechanism needs to be further explored.

Objective:To investigate the expression of N6-methyladenosine(m6A) modification-related genes and their possible roles in peripheral blood mononuclear cells (PBMCs) of patients with primary gouty arthritis (GA).Methods:Forty-five patients each with acute gout (AG), intermittent gout (IG), and age-and gender-matched healthy controls (HC) were collected from the outpatient clinic of the Department of Rheumatology and Immunology of the Affiliated Hospital of Chuanbei Medical College between October and December of 2023. The expression levels of m6A modification-related genes (METTL3、METTL14、WTAP、FTO、ALKBH5、IGF2BP2、IGF2BP3、YTHDF1、YTHDC2) in PBMCs among the 3 groups were detected by RT-qPCR and correlation analysis with clinical indicators was performed. Measurements conforming to normal distribution were analyzed using ANOVA or t-tests, and data were analyzed using the Kruskal-Wallis H-test and Mann-Whitney U-test for data that is not-normaly distributed. The value of m6A modification-related genes for the diagnosis of GA was evaluated using subject characterization curve ROC. Results:①There were statistically significant differences in the expression of IGF2BP2 ( Z=-3.59, P<0.001)、WTAP ( Z=-5.25, P<0.001)、METTL14 ( Z=-3.62, P<0.001)、YTHDF1 ( Z=-2.12, P=0.034)and YTHDC2 ( Z=-2.00, P=0.045) in the disease group and the normal control group. Among them, the expression of IGF2BP2 in the GA group [28.08 (17.99, 47.06)×10 -4] was significantly higher than that in the HC group [19.23 (12.90, 25.78)×10 -4], and the expressions of WTAP、METTL14、YTHDF1 and YTHDC2 in the GA group [298.61 (213.61, 377.80)×10 -4, 9.94 (6.43, 13.46)×10 -4, 52.63 (28.22, 72.77)×10 -4, 40.24 (20.74, 73.32)×10 -4] were significantly lower than those in the HC group [398.45(339.88, 454.89)×10 -4, 13.27(11.07, 15.85)×10 -4, 64.43(43.61, 87.10)×10 -4, 53.11(36.37, 79.28)×10 -4]. Further subgroup analysis revealed statistically significant differences in the expression of IGF2BP2、WTAP、METTL14、YTHDF1 and YTHDC2 among the 3 groups ( H=19.62、31.73、13.14、16.64、28.90, all P≤0.001). The expressions of WTAP and METTL14 in the AG group [311.13(234.96, 426.67)×10 -4, Z=-3.27, P=0.001; 9.64 (5.21, 15.21)×10 -4, Z=-2.71, P=0.008] and IG group [272.27 (203.29, 347.95)×10 -4, Z=-5.78, P<0.001; 10.40(6.88, 12.88)×10 -4, Z=-3.54, P=0.003] were lower than those in the HC group [398.45 (339.88, 454.89)×10 -4, 13.27(11.07, 15.85)×10 -4]. However, there was no significant difference between AG and IG group ( P>0.05). Both YTHDF1 and YTHDC2 were significantly lower in the AG group [38.10(16.19, 56.78)×10 -4, 24.31 (14.35, 42.77)×10 -4] than those in the IG group [64.13 (48.28, 74.40)×10 -4(Z=-3.54, P<0.001, 65.49 (39.89, 91.23)×10 -4(Z=-4.96, P<0.001)] and HC group [64.43 (43.61, 86.92)×10 -4(Z=-3.51, P<0.001), 53.11 (36.37, 79.28)×10 -4(Z=-4.25, P<0.001)]. But there was no statistically significant difference between IG and HC groups ( P>0.05); IGF2BP2 was significantly lower in the AG group [25.32(16.40, 40.43)×10 -4, Z=-2.46, P=0.014] and HC group [19.23 (12.90, 25.78)×10 -4, Z=-4.54, P<0.001] than in the IG group [31.10(22.60, 49.58)×10 -4], but the comparison between AG and HC showed no statistically significant difference( P>0.05). ②Spearman correlation analysis showed that in GA patients, the expression of IGF2BP2、METTL14 and YTHDF1 was positively correlated with plasma glucose、blood uric acid(sUA) and total cholesterol level respectively ( r=0.22, P=0.037; r=0.38, P=0.003; r=0.23, P=0.034), and WTAP was negatively correlated with GLU ( r=-0.25, P=0.020). ③The ROC curve for the joint prediction of the five differential genes showed that the 95% CI for area under the curve in GA was 0.90 (0.84, 0.95). Conclusion:The m6A modification-related genes are abnormally expressed in GA and are correlated with clinical indicators such as GLU and UA, which are hypothesized to be involved in the pathogenesis of GA and have a certain reference value for the evaluation of metabolism in GA patients.

Objective:To explore the incidence of secondary hemophagocytic lymphohistiocytosis (sHLH) in elderly patients with severe SARS-CoV-2 infection, and to analyze and summarize its clinical features and risk factors for early identification of high-risk groups.Methods:A retrospective cohort study was conducted. From January to May 2020, No. 960 Hospital of People's Liberation Army, the Second Hospital Affiliated to Cheeloo College of Medicine of Shandong Province, the First Rehabilitation Hospital of Shandong Province, the Public Health Clinical Center Affiliated to Shandong University, and Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine received 248 patients over 60 years old who were diagnosed with severe SARS-CoV-2 infection during their assistance to Hubei or support for diagnosis and treatment of SARS-CoV-2 infection in Shandong Province. The clinical data of patients were collected. According to the hemophagocytic lymphohistiocytosis diagnosis scoring (HScore) criteria, the patients were divided into sHLH group (HScore > 169) and non-sHLH group (HScore < 98). The demographic data, clinical features, laboratory results, the proportion of organ failure and 60-day mortality of patients were collected and compared between the two groups. The risk factors of sHLH and 60-day death were evaluated through binary multivariate Logistic regression analysis in elderly patients with severe SARS-CoV-2 infection. The receiver operator characteristic curve (ROC curve) was plotted to analyze the diagnostic value of indicators only or combined for sHLH.Results:Among 248 elderly patients with severe SARS-CoV-2 infection, 82 patients with incomplete data and untraceable clinical outcomes, and 35 patients with HScore of 98-169 were excluded. Finally, 131 patients were enrolled in the final follow-up and statistics, including 25 patients in the sHLH group and 106 patients in the non-sHLH group. Compared with the non-sHLH group, plasma albumin (ALB), hemoglobin (Hb), lymphocyte count (LYM), platelet count (PLT), fibrinogen (Fib) and prealbumin (PAB) in the sHLH group were significantly reduced, while alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), MB isoenzyme of creatine kinase (CK-MB), serum creatinine (SCr), C-reactive protein (CRP), D-dimer, ferritin (Fer), lactate dehydrogenase (LDH), procalcitonin (PCT), cardiac troponin I (cTnI), triglycerides (TG), interleukin-6 (IL-6), total bilirubin (TBil) were significantly higher. The fever and fatigue in the sHLH group were more severe than those in the non-sHLH group, and the patients in the sHLH group had higher rates of shock, acute kidney injury, liver dysfunction, and cardiac injury than the non-sHLH group. The 60-day mortality of patient in the sHLH group was significantly higher than that in the non-sHLH group [84.0% (21/25) vs. 40.6% (43/106), P < 0.01]. Binary multivariate Logistic regression analysis showed that high Fer [odds ratio ( OR) = 0.997, 95% confidence interval (95% CI) was 0.996-0.998], D-dimer ( OR = 0.960, 95% CI was 0.944-0.977), LDH ( OR = 0.998, 95% CI was 0.997-0.999) and TG ( OR = 0.706, 95% CI was 0.579-0.860) were independent risk factors for sHLH in elderly patients with severe SARS-CoV-2 infection (all P < 0.01), while elevated Fer ( OR = 1.001, 95% CI was 1.001-1.002), LDH ( OR = 1.004, 95% CI was 1.002-1.005) and D-dimer ( OR = 1.036, 95% CI was 1.018-1.055) were independent risk factors for 60-day death of patients (all P < 0.01). The death risk of the sHLH patients was 7.692 times higher than that of the non-sHLH patients ( OR = 7.692, 95% CI was 2.466-23.987, P = 0.000). ROC curve analysis showed that a three-composite-index composed of LDH, D-dimer and TG had good diagnostic value for sHLH in elderly patients with severe SARS-CoV-2 infection [area under the ROC curve (AUC) = 0.920, 95% CI was 0.866-0.973, P = 0.000]. Conclusions:Elderly patients with severe SARS-CoV-2 infection complicated by sHLH tend to be critically ill and have refractory status and worse prognosis. High Fer, LDH, D-dimer and TG are independent risk factors for sHLH, and are highly suggestive of poor outcome. The comprehensive index composed of LDH, D-dimer and TG has good diagnostic value, and can be used as an early screening tool for sHLH in elderly patients with severe SARS-CoV-2 infection.

Objective:To investigate the clinical characteristics and short-term follow-up outcomes of primary nephrotic syndrome (PNS) children infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the Omicron variant outbreak in Shanghai, and to provide a reliable reference for clinicians in the diagnosis and treatment.Methods:It was a case-control study. The clinical data of children with PNS (PNS group) who were diagnosed and followed-up up to 1 year in the nephrology department of four children's medical centers in Shanghai, and the children (control group) who had no underlying diseases and were infected with SARS-CoV-2 in Shanghai Jinshan Public Health Center, including the data when they were infected with SARS-CoV-2, were retrospectively analyzed.Results:(1) From March 30th to April 13th, 2022, 6 PNS children in Shanghai were infected with SARS-CoV-2, including 5 boys and 1 girl. The median age was 4.5 (2.0, 11.0) years old. And 30 children were matched by sex, age and disease type as control group, including 20 males and 10 females. The median age was 4.5 (2.0, 9.0) years. There were no significant differences between the PNS group and the control group in clinical symptoms (including fever duration), treatment regimens, vaccine doses and virus clearance time (all P>0.05). (2) The 6 children with PNS included 3 cases of steroid-sensitive type, 3 cases of steroid-resistant type, 2 cases of minimal change disease, 2 cases of focal segmental glomerulosclerosis and 2 cases with no renal biopsy. Before SARS-CoV-2 infection, their primary disease-PNS were stable, and urine protein was negative, four of them were under maintenance treatment with oral steroids or immunosuppressive drugs. At the time of SARS-CoV-2 infection, the symptoms of all of the 6 cases were mild, no severe, critical or fatal cases, and they were all cured and discharged from hospital through medical isolation observation or symptomatic treatment of infections. (3) Five cases of them still had discomfort symptoms such as cough, anorexia, and fatigue after being discharged from the hospital, which lasted for about 1 week. Within 1 year of follow-up, none of the children have suffered from "recurrent positive PCR results" or "secondary infection" of the SARS-CoV-2. (4) Among them, 4 cases of PNS relapsed after SARS-CoV-2 infection, timely addition of steroids was effective, their urine protein quickly turned negative, and there was no recurrence after 1 year of follow-up. (5) Before infection with SARS-CoV-2, the levels of immunoglobulin IgG were lower than the normal reference value in the 4 cases with PNS recurrence. Conclusions:During the Omicron variant outbreak in Shanghai, the infection of SARS-CoV-2 in children with PNS are resulted in high transmission among household contacts. Most of them have mild symptoms and good prognosis. PNS is prone to relapse after SARS-CoV-2 infection, and steroid therapy is effective and safe for these relapse. IgG may be a potential marker for the prognosis of PNS children infected with SARS-CoV-2.

Early childhood caries (ECC) is a significant chronic disease of childhood and a rising public health burden worldwide. ECC may cause a higher risk of new caries lesions in both primary and permanent dentition, affecting lifelong oral health. The occurrence of ECC has been closely related to the core microbiome change in the oral cavity, which may be influenced by diet habits, oral health management, fluoride use, and dental manipulations. So, it is essential to improve parental oral health and awareness of health care, to establish a dental home at the early stage of childhood, and make an individualized caries management plan. Dental interventions according to the minimally invasive concept should be carried out to treat dental caries. This expert consensus mainly discusses the etiology of ECC, caries-risk assessment of children, prevention and treatment plan of ECC, aiming to achieve lifelong oral health.
