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 compare the therapeutic efficacy and safety of local anesthesia and spinal anesthesia for the patients with varicocele (VC) who underwent microsurgical varicocelectomy (MV). METHODS: We retrospectively analyzed the data of VC patients who underwent MV treatment at the Andrology Department of the Affiliated Ruikang Hospital of Guangxi University of Chinese Medicine from May 2020 to March 2023. Cases with complete clinical data and follow-up evaluation were selected and divided into a control group (spinal anesthesia) and an observation group (local anesthesia) according to different anesthesia methods. The surgical time (including anesthesia time), visual analogue scale (VAS) score for pain, hospital stay, treatment cost, sperm concentration, forward motile sperm rate, and normal sperm morphology rate after three months of surgery, as well as postoperative complications and recurrence rate were compared between the two groups. RESULTS: A total of 107 eligible cases were included, with 56 cases in the control group and 51 cases in the observation group. There was no significant difference in the VAS score for pain during and after four hours of surgery, as well as postoperative complications, and recurrence rate between the two groups (P> 0.05). There was an significant increase in sperm concentration, forward motile sperm rate, and normal sperm morphology rate in both of two groups after three months of surgery (P<0.05). However, there was no significant difference between the two groups three months after surgery (P>0.05). The surgical time and hospital stay were shorter than those of the control group (P<0.05). And the treatment cost in observation group was lower than that of the control group (P<0.05). CONCLUSION Both local anesthesia and lumbar anesthesia for MV treatment of VC have good efficacy and safety. However, patients treated with MV under local anesthesia for VC have obvious advantages in terms of operation time (including anesthesia time), hospital stay, and treatment cost, which is worthy of clinical promotion and application.

Autophagy is an essential cellular metabolic process that involves clearance of damaged organelles and protein aggregates in cells through lysosomes,providing energy for cells,and maintaining cellular tissue homeostasis.Impaired autophagy is closely related to the pathophysiology of a variety of diseases.In the pathogenesis of atherosclerosis(AS),the dysfunction of autophagy of vascular cells plays a crucial role in the formation and progression of AS.The functional status,survival or death of vascular cells,including endothelial cells,vascular smooth muscle cells and macrophages,can influence the formation and stability of plaques,thereby affecting the progression of AS.This review summarizes the relationship between autophagy and AS,and details the impact of autophagy dysfunction on vascular cell function in the process of AS,as well as the role of mitophagy and inflammasome in the development of AS,aiming to provide novel insights for the prevention and treatment of AS.

Objective To explore the current status of H.pylori infection in the natural population of Sanya City,analyze its influencing factors,and provide a reference basis for the prevention and control of H.pylori infection.Methods A total of 677 residents from four districts of Sanya City were selected by overall stratified random sampling method,and were subjected to urea 14C breath test and questionnaire survey to calculate the positive rate of H.pylori in the natural population and analyze the influencing factors of H.pylori infection.Results A total of 606 residents were included,and the number of H.pylori positive detections was 261,with a positive detection rate of 38.5％.Among them,different ethnicity,marital status,smoking,eating vegetables and fruits,and literacy level were associated with H.pylori infection(P＜0.05);gender,age,BMI,alcohol consumption,drinking water source,betel quid chewing,and the number of cohabitants were not significantly associated with H.pylori infection(P＞0.05).Family infection was an independent risk factor for H.pylori infection in the natural population of Sanya City,and Li ethnicity,frequent consumption of fruits and vegetables,and college and higher education level were independent protective factors for H.pylori infection in the natural population of Sanya City.Conclusion The rate of H.pylori infection in the natural population of Sanya City is lower than the national average.Consuming more fruits and vegetables and improving the awareness of hygiene protection are conducive to the prevention of H.pylori infection;and the promotion of the family and related members with the same examination and treatment is important to avoid aggregation of infection within the family.

Objective: To propose a new staging system for presacral recurrence of rectal cancer and explore the factors influencing radical resection of such recurrences based on this staging system. Methods: In this retrospective observational study, clinical data of 51 patients with presacral recurrence of rectal cancer who had undergone surgical treatment in the Department of Gastrointestinal Surgery, Peking University People's Hospital between January 2008 and September 2022 were collected. Inclusion criteria were as follows: (1) primary rectal cancer without distant metastasis that had been radically resected; (2) pre-sacral recurrence of rectal cancer confirmed by multi-disciplinary team assessment based on CT, MRI, positron emission tomography, physical examination, surgical exploration, and pathological examination of biopsy tissue in some cases; and (3) complete inpatient, outpatient and follow-up data. The patients were allocated to radical resection and non-radical resection groups according to postoperative pathological findings. The study included: (1) classification of pre-sacral recurrence of rectal cancer according to its anatomical characteristics as follows: Type I: no involvement of the sacrum; Type II: involvement of the low sacrum, but no other sites; Type III: involvement of the high sacrum, but no other sites; and Type IV: involvement of the sacrum and other sites. (2) Assessment of postoperative presacral recurrence, overall survival from surgery to recurrence, and duration of disease-free survival. (3) Analysis of factors affecting radical resection of pre-sacral recurrence of rectal cancer. Non-normally distributed measures are expressed as median (range). The Mann-Whitney U test was used for comparison between groups. Results: The median follow-up was 25 (2-96) months with a 100% follow-up rate. The rate of metachronic distant metastasis was significantly lower in the radical resection than in the non-radical resection group (24.1% [7/29] vs. 54.5% [12/22], χ²=8.333, P=0.026). Postoperative disease-free survival was longer in the radical resection group (32.7 months [3.0-63.0] vs. 16.1 [1.0-41.0], Z=8.907, P=0.005). Overall survival was longer in the radical resection group (39.2 [3.0-66.0] months vs. 28.1 [1.0-52.0] months, Z=1.042, P=0.354). According to univariate analysis, age, sex, distance between the tumor and anal verge, primary tumor pT stage, and primary tumor grading were not associated with achieving R0 resection of presacral recurrences of rectal cancer (all P>0.05), whereas primary tumor pN stage, anatomic staging of presacral recurrence, and procedure for managing presacral recurrence were associated with rate of R0 resection (all P<0.05). According to multifactorial analysis, the pathological stage of the primary tumor pN1-2 (OR=3.506, 95% CI: 1.089-11.291, P=0.035), type of procedure (transabdominal resection: OR=29.250, 95% CI: 2.789 - 306.811, P=0.005; combined abdominal perineal resection: OR=26.000, 95% CI: 2.219-304.702, P=0.009), and anatomical stage of presacral recurrence (Type III: OR=16.000, 95% CI: 1.542 - 166.305, P = 0.020; type IV: OR= 36.667, 95% CI: 3.261 - 412.258, P = 0.004) were all independent risk factors for achieving radical resection of anterior sacral recurrence after rectal cancer surgery. Conclusion: Stage of presacral recurrences of rectal cancer is an independent predictor of achieving R0 resection. It is possible to predict whether radical resection can be achieved on the basis of the patient's medical history.

Objective: To identify the internal nasal valve (INV) and to evaluate its key parameters in the established 3D models of nasal cavity space via Mimics from CT images, in order to provide evidence for quantitative diagnosis of nasal valve compromise. Methods: A total of 32 Han adults without nasal diseases who underwent maxillofacial CT test in Shanghai Ninth People's Hospital from January 2015 to December 2018 were retrospectively recruited, including 16 males and 16 females, with the age ranged from 20 to 80 years (50% age<50 years old). Maxillofacial CT images were used to create 3D model of nasal cavity space. The INV was identified and the following parameters were measured: the angle between the INV and the nasal bone (θ_INV-B), unilateral cross-sectional area of the INV (A_INV-R, A_INV-L), total cross-sectional area of the INV (A_INV), unilateral height of the INV (H_INV-R, H_INV-L), unilateral nasal valve angle (α_INV-R, α_INV-L), and the sum of nasal valve angle (α_INV). The A_INV in our study was compared with the results of the previously adopted planes (Plane_C, perpendicular to the hard palate and Plane_B, plane perpendicular to the nasal bone). The parameters above were compared among genders, age and race groups. SPSS 26 and GraphPad Prism 9 software were used for statistical analysis and mapping of data. Results: The A_INV in our study was (214.87±52.94) mm², which was significantly less than that of Plane_C (254.97±47.80) mm² and Plane_B (226.07±57.36) mm². The measured parameters were as follows: θ_INV-B was (82.07±7.06)°; A_INV-R was (112.66±31.39) mm²; A_INV-L was (102.21±27.14) mm²; A_INV was (214.87±52.94) mm²; H_INV-R was (24.87±4.62) mm; H_INV-L was (24.35±4.86) mm; α_INV-R was (20.48±2.99)°; α_INV-L was (19.65±3.82)°; α_INV was (40.13±6.24)°. The A_INV-R was larger than A_INV-L (t=2.33, P<0.05); The H_INV, A_INV-R, A_INV-L and A_INV of males were more than those of females (t value was 5.77, 3.21, 2.91 and 3.52, respectively, all P<0.01). The A_INV of the young group (<50 years) was larger than that of the old group (t=2.83, P<0.01); The θ_INV-B was different between the Han people and the Caucasian (t=2.92,P<0.01). The α_INV of the Han people was larger than that of Caucasians (Z=-6.92, P<0.01), but the H_INV was smaller (Z=-3.89, P<0.01). Conclusion: The A_INV carried out in 3D models of nasal cavity space is significantly smaller than that obtained by the previous methods of CT evaluation. INV static parameters differ among genders, age and race groups.

Objective:To analyze the expression of targeting protein for Xklp2 (TPX2) in kidney renal clear cell carcinoma (KIRC) and its clinical significance.Methods:The postoperative tissue samples of 54 patients with KIRC admitted to the Department of Urology, the First Affiliated Hospital of Bengbu Medical College from July 2017 to June 2019 were collected. Immunohistochemistry was used to detect the protein expression of TPX2 in renal carcinoma and paracancerous tissues. The difference of TPX2 mRNA expression between KIRC tissues and normal tissues was analyzed by using the TIMER database, which verified the immunohistochemical results. The UALCAN database and the Kaplan-Meier plotter database were used to analyze the relationship between TPX2 mRNA expression and clinical stage, molecular subtypes, lymph node metastasis, and prognosis of patients with KIRC. The protein interaction network was constructed by STRING database to obtain TPX2-related proteins, and the genes corresponding to the related proteins were enriched for the KEGG pathway. The relationship between TPX2 expression and immune cell infiltration and the immune checkpoint was studied by using the TIMER database.Results:Immunohistochemical results showed that the positive expression rate of TPX2 protein was 48.15% (26/54) in cancer tissues, which was higher than that in paracancerous tissues (20.37%, 11/54) ( χ2=9.25, P=0.002). The results of bioinformatics analysis showed that TPX2 mRNA expression was significantly up-regulated in KIRC [cancer tissue: 1.89 (1.49, 2.42), normal tissue: 0.35 (0.24, 0.57), U=2 297.00, P<0.001]. The expression of TPX2 mRNA was related to the clinical stage ( χ2=34.36, P<0.001), molecular subtypes ( χ2=30.15, P<0.001), and lymph node metastasis status ( χ2=27.21, P<0.001) of KIRC patients. The 5-year survival rate (53.80%) in patients with high TPX2 expression was lower than that in patients with low TPX2 expression (74.40%, χ2=18.87, P<0.001). STRING database protein interaction network construction obtained 20 TPX2-related proteins, and the genes corresponding to the related proteins were enriched in the cell cycle. The expression of TPX2 was positively correlated with B cells ( r=0.30, P<0.001), CD8 + T cells ( r=0.23, P<0.001), CD4 + T cells ( r=0.18, P<0.001), macrophages ( r=0.20, P<0.001), neutrophils ( r=0.31, P<0.001), dendritic cells ( r=0.39, P<0.001) infiltration and most of its biomarkers (all P<0.05). It was positively correlated with immune checkpoint PD-1 ( r=0.31, P<0.001) and CTLA-4 ( r=0.27, P<0.001), but not correlated with PD-L1 ( r=0.07, P=0.146) . Conclusion:TPX2 is highly expressed in KIRC and is closely associated with poor prognosis. It is expected to be a new therapeutic target for KIRC.

OBJECTIVE: Foreign studies have reported that coronary artery disease (CAD) patients with high baseline low-density lipoprotein cholesterol (LDL-C) may have a good prognosis, which is called the "cholesterol paradox". This study aimed to examine whether the "cholesterol paradox" also exists in the Chinese population. METHODS: A total of 2,056 patients who underwent the first percutaneous coronary intervention (PCI) between 2014 and 2016 were enrolled in this retrospective cohort study and classified into two groups based on baseline LDL-C = 2.6 mmol/L (100 mg/dL). The outcomes of interest included major adverse cardiovascular events (MACE), all-cause mortality, recurrent nonfatal myocardial infarction, unexpected coronary revascularization, or any nonfatal stroke. RESULTS: All-cause mortality occurred in 8 patients (0.7%) from the low-LDL-C group and 12 patients (2.4%) in the high-LDL-C group, with a significant difference between the two groups (adjusted hazard ratio: 4.030, 95% confidence interval: 1.088-14.934; P = 0.037). However, no significant differences existed for the risk of MACE or other secondary endpoints, such as unexpected revascularization, nor any nonfatal stroke in the two groups. CONCLUSION In this study, a high baseline LDL-C was not associated with a low risk of clinical outcomes in CAD patients undergoing first PCI, which suggested that the "cholesterol paradox" may be inapplicable to Chinese populations.

Wax apple (Syzygium samarangense) has received growing research interest for its high nutritional and medicinal value due to its constituents such as polysaccharide, organic acids, flavonoids, minerals, and other substances. In this study, wax apple polysaccharide (WAP) was isolated from this plant and its protective effect against ethyl carbamate (EC)‍-induced oxidative damage was evaluated in human hepatocytes (L02 cells). Firstly, a series of analyses such as high-performance liquid chromatography (HPLC), high-performance gel permeation chromatography (HPGPC), Fourier transform infrared spectroscopy (FT-IR), gas chromatography/mass spectrometry (GC/MS), and ¹H and ¹³C nuclear magnetic resonance (NMR) were conducted to identify the structure of WAP. Thereafter, in vitro cell experiments were performed to verify the protective effects of WAP against EC-induced cytotoxicity, genotoxicity, and oxidative damage in L02 cells. Our results revealed that WAP is composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, arabinose, and fucose in a molar ratio of 2.20:‍3.94:‍4.45:‍8.56:‍8.86:‍30.82:‍39.78:‍1.48. Using a combination of methylation and NMR spectroscopic analysis, the primary structure of WAP was identified as Araf-(1→, Glcp-(1→, →2)‍-Araf-(1→, →3)‍-Galp-(1→, →3)‍-Araf-‍(1→, and →6)‍-Galp-‍(1→. Cell experiments indicated that WAP exhibited significant protective effects on EC-treated L02 cells via suppressing cytotoxicity and genotoxicity, reducing reactive oxygen species (ROS) and O₂^•- formation, as well as improving mitochondrial membrane potential (MMP) and glutathione (GSH). In a nutshell, WAP has the potential as an important therapeutic agent or supplement for hepatic oxidative damage. Meanwhile, further studies are needed to prove the above effects in vivo at the biological and clinical levels.
