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 36th 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 investigate the penile appearance, sexual function, psychological status and related influencing factors of adult patients who underwent hypospadias repair surgery in their minors, so as to provide reference for the diagnosis, treatment and prognosis of hypospadias. 【Methods】 This study included 50 adult hypospadias patients who underwent urethroplasty in our hospital during May 2005 and Aug. 2018. The present appearance, sexual function and psychological status were evaluated. The correlation and consistency between hypospadias objective scoring evaluation (HOSE) and pediatric penile perception score (PPPS) were analyzed. Factors affecting the results were determined with univariate and multivariate regression analysis. 【Results】 The satisfaction rate of HOSE was significantly correlated with the urethral length and complications (P=0.024, P=0.033). The satisfaction rate of PPPS was significantly correlated with the number of urethral operations and postoperative complications (P=0.041, P=0.023). There was a weak correlation between HOSE and PPPS (r=0.291, P=0.040), but almost no consistency (Kappa=0.2, P=0.107). Sixty percent of the patients paid attention to the ventral appearance of penis, whose dissatisfaction rate of PPPS was higher than those who did not pay attention to the ventral appearance of the penis (19/30 vs. 6/20, P=0.021). Patients with multiple operations (>1), postoperative complications or unsatisfactory penile appearance were more likely to have inferiority complex (52.6% vs. 22.6%, P=0.029; 59.1% vs.14.3%, P=0.001;61.5% vs. 24.3%, P=0.015). Multivariate regression analysis showed that dissatisfaction with the appearance of the penis was an independent risk factor for patients’ perception of their own physical defects. Among the patients who believed that they had physical defects, the percentage of patients with grade IV penile erectile hardness was significantly lower than that of those who denied they had physical defects (9/17 vs. 27/33, P=0.047). 【Conclusion】 The undesirable postoperative penis appearance is likely to have a negative impact on patients’ long-term psychological state, which might further damage the sexual function in adulthood. Surgeons should pay attention to the penile appearance during the conduction of hypospadias repair.

The count and recognition of white blood cells in blood smear images play an important role in the diagnosis of blood diseases including leukemia. Traditional manual test results are easily disturbed by many factors. It is necessary to develop an automatic leukocyte analysis system to provide doctors with auxiliary diagnosis, and blood leukocyte segmentation is the basis of automatic analysis. In this paper, we improved the U-Net model and proposed a segmentation algorithm of leukocyte image based on dual path and atrous spatial pyramid pooling. Firstly, the dual path network was introduced into the feature encoder to extract multi-scale leukocyte features, and the atrous spatial pyramid pooling was used to enhance the feature extraction ability of the network. Then the feature decoder composed of convolution and deconvolution was used to restore the segmented target to the original image size to realize the pixel level segmentation of blood leukocytes. Finally, qualitative and quantitative experiments were carried out on three leukocyte data sets to verify the effectiveness of the algorithm. The results showed that compared with other representative algorithms, the proposed blood leukocyte segmentation algorithm had better segmentation results, and the mIoU value could reach more than 0.97. It is hoped that the method could be conducive to the automatic auxiliary diagnosis of blood diseases in the future.

Objective To evaluate the effectiveness and benefit of influenza vaccination among school-age children in Xining, Qinghai. Methods A total of 215 children were randomly recruited as the vaccination group and vaccinated with trivalent split influenza vaccine. At the same time, 215 healthy children (no known diseases and past history reported, and no vaccinations) who underwent physical examinations during the same period were selected as the control group. The basic demographic information was investigated and a 1-year follow-up was carried out. Results The demographic characteristics of children in the vaccinated group and the control group were not significantly different (P>0.05), and were comparable between the two groups. After four follow-up visits within one year for the enrolled children, the overall incidence of influenza-like illness in children in the vaccinated group and the control group was 7.4% (16/215) and 16.7% (36/215), respectively, and the difference was statistically significant (χ2=8.75, P<0.05). The protection rate was 55.7%, and the protection index was 2.26. The common cold incidence rates in the two groups were 16.7% (36/215) and 25.6% (55/215), respectively, and the difference was statistically significant (χ2=5.03, P<0.05). The protection rate was 35.0%, and the protection index was 1.54. The incidence of other respiratory diseases was 1.8% (4/215) and 3.8% (8/215), respectively, and the difference was not statistically significant (χ2=1.37, P>0.05). The protection rate was 52.6%, and the protection index was 2.11. The proportions of irrational use of antibiotics were 6.0% (13/215) and 20.9% (45/215), respectively, and the difference was statistically significant (χ2=20.41, P<0.05). The protection rate was 71.3%, and the protection index was 3.48. The per capita income from vaccination was 667.9 yuan, and the benefit-cost ratio was 9.97:1. Conclusion Influenza vaccination for school-age children can effectively prevent the incidence of influenza-like diseases and the common cold, and the vaccination is cost-effective.

Objective:To develop a novel α vβ 3-targeted theranostic agent 177Lu-Evans blue (EB)-Arg-Gly-Asp (RGD) and evaluate its value for SPECT imaging and targeted radionuclide therapy in the non-small cell lung cancer (NSCLC)-patient-derived xenografts (PDX). Methods:The α vβ 3-targeted molecule RGD was conjugated with the albumin binding moiety EB to obtain EB-RGD, and EB-RGD was further conjugated with the chelator 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA) for 177Lu radiolabeling. NSCLC-PDX mice models ( n=68) were established. 177Lu-EB-RGD SPECT imaging, biodistribution study were performed in 28 PDX mice models after being injected with 177Lu-EB-RGD or 177Lu-RGD. Targeted radionuclide therapy were subsequently performed in NSCLC-PDX mice models, saline group (group A), 18.5 MBq 177Lu-RGD group (group B), 18.5 MBq 177Lu-EB-RGD group (group C), 29.6 MBq 177Lu-EB-RGD group (group D), n=10 in each group; tumor volumes of PDX mice models in each group were observed within 50 d. Differences between 2 groups were compared using independent-sample t test. Results:177Lu-EB-RGD was radiolabeled at a specific activity of (55±14) GBq/μmol, with a radiochemical yield of more than 95% and a radiochemical purity of more than 95%. Regarding the SPECT imaging, tumors in NSCLC-PDX mice were clearly observed from 4 to 96 h post-injection and the tumor to muscle ratio (T/M) reached 7.34±0.67, 14.63±3.82, 15.69±3.58 and 15.99±5.42 at 4, 24, 72, 96 h post-injection, respectively. Biodistribution study further confirmed the findings from SPECT imaging, and the tumor uptake of 177Lu-EB-RGD were markedly increased compared to 177Lu-RGD 4 h post-injection ((10.15±1.17) vs (3.30±1.47) percent injection dose per gram (%ID/g); t=18.60, P<0.05). Regarding targeted radiotherapy, the tumor volumes were quickly increased within 50 d after treatment in group A and B, while the tumor volumes were decreased in group C and D, until the tumors in group C and D disappeared at the 28th day after initial treatment with no sign of recurrence during the observation period. Conclusions:177Lu-EB-RGD can target α vβ 3-positive NSCLC-PDX with intense tumor to background ratio and strong tumor inhibition efficacy. The preclinical data suggests that 177Lu-EB-RGD may be an effective new treatment option for advanced NSCLC patients with resistance or ineffective results for targeted therapy.

Objective:To investigate the therapeutic efficacy and potential mechanisms of integrin α vβ 3-targeted radionuclide therapy (TRT) in combination with anti-programmed cell death protein ligand 1 (PD-L1) immunotherapy. Methods:Integrin α vβ 3-targeted molecule Arg-Gly-Asp (RGD) was conjugated with Evans blue (EB) and then labeled with 177Lu to obtain 177Lu-EB-RGD. The radioactivity and radiochemical purity were determined. MicroSPECT imaging, biodistribution, and in vivo therapeutic efficacy were subsequently performed in MC38 murine colon cancer models. Volume of tumor and body mass of mice were observed to assess the therapeutic efficacy and safety ( n=9 in each group). Flow cytometry was used to evaluate therapy response of saline-treated (control, group A), 18.5 MBq 177Lu-EB-RGD-treated (group B), 10 mg/kg PD-L1 antibody-treated (group C), TRT combined with immunotherapy-treated (group D, 18.5 MBq 177Lu-EB-RGD and 10 mg/kg PD-L1 antibody) mice and alterations in tumor microenvironment (PD-L1 + immune cells, CD8 + T cells and regulatory T cells). Independent-sample t test and repeated measures analysis of variance were used for data analysis. Results:The radioactivity of 177Lu-EB-RGD was (55.85±14.00) GBq/μmol. SPECT imaging clearly visualized the MC38 tumors in mice models with high uptake and long retention time, the tumor/muscle ratio reached 14.87±0.88 at 24 h postinjection, while less uptake and retention in normal tissues. Tumor uptake of 177Lu-EB-RGD was significantly higher than that of 177Lu-RGD 4 h post-injection ((12.00±1.60) vs (3.69±0.37) %ID/g; t=8.63, P<0.01). The efficacy results between each treatment group was significantly different ( F=7.32, P=0.03) at day 6 post-treatment. The combination therapy showed the most outstanding anti-tumor efficacy with 7/9 mice showed complete response. Flow cytometry results showed that TRT up-regulated the PD-L1 expression significantly, namely, PD-L1 + immune cells in group B and group A were significantly different (CD45 + /PD-L1: 2.34% vs 0.95%, CD11b + /PD-L1: 2.41% vs 0.66%; t values: 11.17 and 8.70, both P<0.01); immunotherapy and combination therapy dramatically stimulated the infiltration of CD8 + T cells (2.07% vs 0.26%, 2.71% vs 0.26%; t values: 4.10 and 6.03, both P<0.05). Conclusion:TRT in combination with immunotherapy synergistically enhance anti-tumor efficacy, which is expected to play a role in the treatment of patients with advanced tumor where TRT can be applied.
