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 predict the autophagy-related pathogenesis and key diagnostic genes of diabetic kidney disease (DKD) through bioinformatics analysis, and to identify related Chinese medicines. [Methods] : Data from sequencing microarrays GSE30528, GSE30529, and GSE1009 in the Gene Expression Omnibus (GEO) were employed. Differentially expressed genes (DEGs) with adjusted P < 0.05 from GSE30528 and GSE30529 were identified. Combining these DEGs with the human autophagy gene database, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, and protein-protein interaction (PPI) network analysis were conducted on the obtained DKD autophagy-related genes. Subsequently, the least absolute shrinkage and selection operator (LASSO) regression and support vector machine-recursive feature elimination (SVM-RFE) algorithms were adopted to select autophagy-related genes. The diagnostic capability of these genes was assessed through analysis with the external validation set from microarray GSE1009, and relevant Chinese medicines were inversely predicted using the SymMap database. [Results] : A total of 2 014 DEGs were selected from GSE30528 and GSE30529, leading to the identification of 37 DKD autophagy-related genes. GO analysis indicated 681 biological mechanisms, including autophagy regulation and plasma membrane microdomain activity. KEGG enrichment analysis identified 112 related signaling pathways. PPI network analysis showed a marked enrichment of autophagy-related genes in DKD. Through LASSO regression and SVM-RFE, four core diagnostic genes for autophagy in DKD were identified: protein phosphatase 1 regulatory subunit 15A (PPP1R15A), hypoxia inducible factor 1 alpha subunit (HIF1α), deleted in liver cancer 1 (DLC1), and ceroid lipofuscinosis neuronal 3 (CLN3). The external validation set demonstrated high diagnostic efficiency for these genes. Finally, 146 kinds of potential Chinese medicines were predicted using the SymMap database, with heatclearing and detoxifying medicine and blood-activating and stasis-eliminating medicine accounting for the largest proportion (25/146 and 13/146, respectively). [Conclusion] This study analyzed and validated bioinformatics sequencing databases to elucidate the potential molecular mechanisms of DKD autophagy and predicted key diagnostic genes, potential therapeutic targets, and related Chinese medicines, laying a solid foundation for clinical research and application.

Dental implantology has developed rapidly for over half a century,since pure titanium(99.7％)dental cylindrical threaded implants were exploited and osseointegration was introduced in 1960s by Prof.Br?nemark.The long term retention rates of 10 years or more are over 95％.However,the biological complications jeopardize the long term effects of dental implant treatment seriously.The prevalence of dental implant biological complications varies greatly among different reports resulting from the disparities on the defini-tions of dental implant biological complications.After analyzing and summarizing the major opinions proposed internationally in recent years,the consensus for the definition of dental implant biological complications has been reached.Generally the dental implant biologi-cal implications can be classified into early stage(before restoration)biological complications and late stage(after restoration)biological complications.The early stage biological complications include acute and chronic infections,pain,soft tissue deficiency,and osseointegration failure,etc.The late stage complications include peri-implant diseases(peri-implant mucositis and peri-implantitis),soft tissue deficiency around implant,implant loosening and dropping off,etc.The various risk factors related to different dental implant biological complications,the strategies of the prevention and treatment for the dental implant biological complications have been discussed comprehensively,and the consensus has been reached.It is aimed to advocate the dentist to pay more attention to the early prevention of the biological implant complications,to promote more researches on the implant biological complications,and to help elevate the level of dental implantology in our country.

Objective To introduce a partially nested design based on the characteristics of TCM in treating the same disease with different treatments and syndrome differentiation and treatment.Methods Partially nested design was used for standardized treatment of complex interventions.The TCM group was divided into multiple subsets according to"syndrome type-treatment method-prescription"(with nested structure),while the control group was treated with standardized Western medicine(without nested structure);taking a case study of"different treatments for the same disease"data for ulcerative colitis,this design type was applied and analyzed using a multi-level model.Results The partially nested design was consistent with the feature of TCM of"different treatments for the same disease"and met the methodological requirements for evidence-based evaluation.Multilevel models allowed analyses with this type of data.Conclusion The use of partially nested design enables the evaluation of the comprehensive effectiveness of"different treatments for the same disease",which can provide a methodological reference for the assessment of clinical effectiveness of TCM.

Chronic HBV infection is an important phase in the natural history of HBV, but there are still controversies over the treatment of this stage. Traditional Chinese medicine has had unique advantages in the prevention and treatment of viral hepatitis since ancient times and plays an important role in prevention and treatment of viral hepatitis in China. Based on the pathological process of chronic HBV infection, the team of Department of Hepatology in Shenzhen Hospital of Traditional Chinese Medicine believes that the core pathogenesis of chronic HBV infection is "kidney deficiency and epidemic toxin lurking in liver blood" and established kidney-tonifying therapy for the treatment of chronic HBV infection. Under the support of the project of Prevention and Treatment of Major Infectious Diseases such as AIDS and Viral Hepatitis in The Eleventh Five Year Plan, The Twelfth Five Year Plan, and The Thirteenth Five Year Plan, the team has conducted studies on the regularity of syndromes and a series of clinical studies and investigated the clinical efficacy of kidney-tonifying therapy through multicenter, randomized, double-blind, placebo-controlled studies, thereby exploring the application and mechanism of traditional Chinese medicine treatment in patients with chronic HBV infection. However, there are still difficulties in the pathogenesis and treatment of chronic HBV infection, and with the inheritance, innovation, and modernization of traditional Chinese medicine, it is believed that traditional Chinese medicine can provide reliable regimens for the treatment of chronic HBV infection.

Objective:To analyze and summarize the clinical effects of 3D printed porous titanium-alloy prosthesis implantation in the treatment of long bone defects of lower extremities.Methods:We retrospectively studied the clinical cases with lower extremity bone defect treated by 3D printed porous titanium prostheses from December 2017 to November 2021. 18 patients who were followed up for more than 12 months were included in this study. The enrolled patients included 12 males and 6 females, with an average of 48.9±22.5 years (range, 13-79 years), and an average body mass index of 23.1±4.3 kg/m 2 (range, 17.2-27.1 kg/m 2). There were 14 osteomyelitis-derived bone defects and 4 nonunion-derived bone defects. The bone defect locations included 10 cases of femur and 8 cases of tibia. The average bone defect distance was 13.9±9.7 cm (range, 5.8-31.2 cm), and the proportion of the defect length to the long bone (femur of tibia) was average 33.7%±16.8% (range, 15.0%-63.0%). The clinical efficacy was comprehensively evaluated through gross observation, imaging evaluation, changes in the total length of lower extremities and long bones, femorotibial angle (FTA) measurement, lower extremity functional scale (LEFS), satisfaction, complications and other indicators, focusing on the stabilization mechanism of the prosthesis and the regeneration of new bone. Results:All 18 patients were followed up for 12-35 months, with an average of 16.3 months. Postoperative X-rays at 1, 3, 12 and 24 months showed that new bone could gradually creep along the prosthesis surface. The preoperative bone defect length of long bone and total length of lower limb were respectively 39.4±4.0 cm and 80.5±5.7 cm, which were different from those of the healthy side by 1.6±1.0 cm and 1.5±1.1 cm. One week after implantation, the length of long bone and lower limb was 39.9±3.5 cm and 80.9±6.2 cm, respectively, and the average difference was 1.0±0.6 cm and 0.9±1.1 cm compared with the healthy side. At the last follow-up, the length of long bone and lower limb was 39.7±3.6 cm and 80.9±7.8 cm, with an average difference of 1.8±1.1 cm and 1.0±0.7 cm from the healthy side. There were no significant differences in the length of long bone and lower limbs at the three time points before surgery, one week after surgery and the last follow-up ( F=0.12, 0.04; P>0.05). The average FTA of the affected limb was 174.7° (173.9°, 175.5°), 175.2°(173.5°, 176.4°), and 175.0°(173.5°, 176.3°) at three time nodes, before surgery, one week after surgery and the last follow-up, respectively, and there was no significant statistical difference in pairwise comparison ( Z=0.01, P>0.05). Patients had a mean LEFS score of 50 (46, 51) at the last follow-up, significantly higher than the preoperative score of 20 (17, 21) ( Z=-5.56, P<0.001). The mean satisfaction score of the 18 patients at the last follow-up was 9.7. Two patients (11.1%) had screw fractures but all 3D printed porous titanium alloy prostheses remained stable without significant loosening or displacement. Two patients (11.1%) had nail channel infection of external fixator, all patients with channel infection were cured by intravenous antibiotics combined with local disinfection and dressing change. Conclusion:The implantation of 3D printed porous titanium-alloy prosthesis could efficiently and safely repair the long bone defects of the lower extremities. The prosthesis could maintain stable in the early and middle postoperative period. The length of the long bones and lower limbs did not change significantly with the weight-bearing and functional exercise of the limbs. The new bone could gradually crawl and grow from both ends of the defect, and the patient's limb function recovered significantly, and the patient's satisfaction was high.

Objective: To analyze the clinical characteristics of oral candidiasis (OC) in in-patients with rheumatism, in order to provide theoretical basis for the prevention and treatment of OC in rheumatism patients. Methods: One thousand eight hundred and eight in-patients were recruited in the Department of Rheumatology, the Second Hospital of Shanxi Medical University from January 2017 to December 2017. The patients included 607 males and 1 201 females. Their average age was (49.5±15.5) years old with a ranging from 14 to 81 years. According to occurrence of OC or not, the patients were divided into OC group and non-OC group. The differences of general data, primary diseases, laboratory examinations, usage of glucocorticoid and immunosuppressant therapy were compared between the two groups, and the risk factors of OC occurrence were analyzed. Results: Two hundred and sixty-nine patients had OC and 1 539 patients had no OC. Age [(54.9±14.7) years], duration of illness [(9.4±4.4) years] and hospital stay [(15.3±5.7) d] in OC group were significantly longer than those in non-OC group. OC incidence in patients with connective tissue disease (CTD) [17.40% (193/1 109)] was higher than that in non-CTD patients [10.87% (75/699)] (P<0.001). OC most likely occurred in patients with such CTD as Sjögren syndrome (SS) and Behcet syndrome. OC incidence in non-CTD patients with osteoarthritis (OA) was highest. The salivary flow rate in OC group [(0.65±0.45) ml/min] was significantly lower than that in non-OC group [(0.78± 0.39) ml/min] (t=2.394, P=0.017). There was no statistical differences in other laboratory examinations between the two groups, including white blood cells (WBC), lymphocyte, platelet count, liver function, renal function, erythrocyte sedimentation rate, C-reactive protein, procalcitonin, immunoglobulin G, immunoglobulin M, immunoglobulin A, C₃, C₄ and so on. OC incidence in patients using prednisone≥15 mg/d [17.16% (133/775)] was higher than that in patients using prednisone<15 mg/d [12.53% (94/750)] and patients not using prednisone [14.84% (42/283)] (P<0.05). The incidence of OC in patients with immunosuppressant therapy [16.11% (226/1 403)] was statistically higher than that in non-immunosuppressant patients [10.62% (43/405)] (P<0.01). Logistic regression analysis showed that the risk factors of OC occurrence included primary diseases (P<0.001), age (P<0.001), duration of illness (P=0.001) and duration of hospitalization (P=0.002). Conclusions OC occurred commonly in rheumatism in-patients, especially in elder patients, patients with long duration of illness and hospital stay. OC incidence in CTD patients is significantly higher than that in non-CTD patients. Glucocorticoid and immunosuppressant therapy might significantly reduce the anti-fungal immunity of the patients.
