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 investigate the additional value of unenhanced computed tomography (CT) in the differential diagnosis of brain tumors and non-neoplastic lesions.Methods:A total of 237 cases [140 males and 97 females; (49±16) years old; including 48 cases of low-grade glioma, 134 cases of high-grade glioma, 38 cases of primary central nervous system lymphoma, 9 cases of medulloblastoma, 5 cases of germinoma, and 3 cases of central neurocytoma] of brain tumors (diffuse gliomas and non-glial tumors) diagnosed by biopsy or surgery and pathology in the Affiliated Hospital of Qingdao University from September 2016 to October 2020 were collected retrospectively. Sixty-six cases [46 males and 20 females; (42±13) years old; including 12 cases of abscesses, 5 cases of infarcts, 33 cases of demyelinating lesions, 11 cases of autoimmune encephalitis, and 5 cases of central nervous system vasculitis] of brain non-neoplastic lesions were confirmed by biopsy or clinic. All patients underwent routine magnetic resonance imaging (MRI) scan and unenhanced CT before the treatment. The images were reviewed by two neuroradiologists together blind to the final diagnosis with and without CT images respectively. The diagnostic results and reliability scores were recorded, and the accuracy of the two evaluations was compared.Results:CT hyperattenuation exhibited a higher specificity (95%) than conventional MRI scan (86%), and a lower diagnostic sensitivity (34% vs 86%). Compared to MRI alone, the combined modality of MRI and unenhanced CT significantly improved diagnostic accuracy (94% vs 86%). Additionally, the CT attenuation ratio of non-neoplastic lesions was significantly lower than that of neoplastic lesions [0.69 (0.61,0.78) and 1.14 (1.00,1.25), W=2 123, P<0.05]. The CT attenuation ratio in the non-glial origin tumor group was significantly higher than that in the diffuse glioma group [1.28 (1.18,1.41) and 1.13 (0.97,1.21), W=1 858, P<0.05]. There was no significant difference in grade Ⅲ and Ⅳ groups of diffuse glioma [1.11 (0.99,1.20) vs 1.16 (1.09,1.24), P>0.05 (Nemenyi test)]. However, both were significantly higher than that of grade Ⅱgroup of diffuse glioma [0.89 (0.76,1.07), P<0.05 (Nemenyi test)]. No significant difference was observed between astrocytic tumors and oligodendroglial tumors at the same grade. Conclusions:Hyperattenuation on unenhanced CT is highly specific for the diagnosis of brain tumors. Unenhanced CT plus MRI is more accurate for distinguishing the two entities in hypoattenuation lesion on unenhanced CT.

Objective:To investigate the distribution and morphological characteristics of brain magnetic resonance imaging (MRI) lesions in patients with myelin oligodendrocyte glycoprotein (MOG) antibody related demyelinating diseases and aquaporin-4 (AQP4) antibody positive neuromyelitis optica spectrum disorders (NMOSD) and their clinical value in early diagnosis.Methods:A total of 35 patients with MOG antibody related demyelinating diseases [20 males and 15 females; aged 31 (25, 43) years] and 36 patients with AQP4 antibody positive NMOSD [3 males and 33 females; aged 42 (29, 54) years] were collected retrospectively from September 2018 to June 2021 in Chenzhou First People′s Hospital and the Affiliated Hospital of Qingdao University which were classified as MOG group and AQP4 positive group respectively. All patients underwent routine cranial MRI scanning before treatment and the location, shape and quantity of intracranial lesions were recorded. Wilcoxon rank sum test was used to compare the number of different types of lesions between the two groups. Logistic regression analysis was used to evaluate the significance of different lesions for the two diseases.Results:There were 7 types of lesions with significant differences in different parts and shapes. Stepwise Logistic regression showed that cortical and juxtacortical lesions ( OR=21.91, 95% CI 3.09-61.69, P<0.05) and infratentorial peripheral white matter lesions ( OR=10.48, 95% CI 2.00-18.89, P<0.05) were the most important risk factors in the MOG group. The incidence of cortical and juxtacortical lesions in the MOG group was 51.4% (18/35), which was higher than that in the AQP4 positive group (2.8%, 1/36; χ2=19.02, P<0.01). The incidence of infratentorial peripheral white matter lesions in the MOG group was 31.4% (11/35), which was higher than that in the AQP4 positive group (5.6%, 2/36; χ2=6.31, P<0.05). Receiver operating characteristic (ROC) curve showed that peripheral lesions [including 6 types of lesions such as supratentorial soft meningitis, cortical encephalitis, cortical and juxtacortical lesions, infratentorial soft meningitis, infratentorial soft meningeal demyelination and infratentorial peripheral lesions, area under curve (AUC)=0.93] were more important than cortical and juxtacortical lesions (AUC=0.75) and central lesions (supratentorial paraventricular white matter lesions, diencephalon, infratentorial paraventricular lesions,AUC=0.64), which had higher diagnostic efficiency. Conclusions:The incidence of intracranial lesions in MOG antibody related demyelinating disease was higher than that in AQP4 positive NMOSD, and the distribution and morphology of intracranial MRI lesions in the two diseases had their characteristic manifestations. Identifying the distribution patterns of peripheral lesions (distributed along pia mater) and central lesions (distributed along ependyma) had a certain reference significance for distinguishing the two groups of diseases.

Objective: To establish a real-time fluorescence recombinase acid amplification (RAA) method for the detection of adenovirus type 3(HAdV-3)without extraction nucleic acid. Methods: According to the conserved sequence of adenovirus type 3 gene, a pair of primers and a probe were designed, and a real-time fluorescence RAA without extracting nucleic acid was established and optimizing the condition of DNA-free extraction. The sensitivity of the method was analyzed by a series of dilution and the specificity of the method was evaluated by detecting the original samples of other respiratory viruses. The clinical samples of HAdV-3 were detected and compared with the traditional real-time fluorescence quantitative PCR method for nucleic acid extraction. Results: The sensitivity of the real-time fluorescence RAA method was as high as that of qPCR in the detection of 10 series diluted HAdV-3 strains. The highest corresponding CT value of qPCR was 36.87. The sensitivity of the real-time fluorescence RAA method was similar to that of the real-time fluorescence quantitative PCR method . There was no cross-reaction to other common types of respiratory viruses. The two method were used to detect 56 clinical samples at the same time, and the result were completely consistent. Conclusions We provide the first report of the real-time fluorescent RAA assays for the detection of HAdV-3 without extracting nucleic acid and it has high sensitivity and specificity. Is suitable for rapid detection of HAdV-3 in clinical laboratories and on-site unite.

Objective To investigate the effect of postoperatively early stage-function-exercise on the recovery of upper limb function of diseased side after breast cancer modified radical mastectomy.Methods One hundred patients with breast cancer admitted to our hospital from January 2013 to June 2016 were collected.All patients underwent modified radical mastectomy.The patients were divided into the observation group and control group after operation,50 cases in each group.The observation group was given the early stage-function-exercise,while the control group received the routine nursing care.The shoulder joint mobility,affected limb edema degree,self-rating anxiety scale (SAS)score,self-rating depression scale (SDS) score and 36-item short-form health survey (SF-36) score were observed in the both groups.Results When compared with the control group,the patients in the observation group got a significant increase in the shoulder joint activity such as antexion,abduction,internal rotation,external rotation,adduction and rear protraction at postoperative 3,6-months (P<0.05).There was no statistically significant difference between the two groups in upper limb volume,SAS score and SDS score before the operation (P>0.05).However,when compared with the control group,the patients in the observation group got a significant decrease of upper limb volume at postoperative 3 months[(1 543.38±414.93) mL vs.(1 635.58±401.58) mL,P=0.000)],a significantly decrease of SAS score[(37.87±6.90) points vs.(44.07±12.32) points,P=0.000)] and SDS score[(38.32±6.65) points vs.(45.02±11.07) points,P=0.000)] at postoperative 6 months,and a significant increase of SF-36 score at postoperative 6 months [(77.52±7.28) points vs.(70.28±7.55) points,P=0.000)].Conclusion Postoperatively early stage-function-exercise can help to improve the shoulder joint activity degree and quality of life,and reduce the limb edema degree after modified radical mastectomy in the patients with breast cancer.

To guarantee the research and establishment of the modern basic theory of traditional Chinese medicine, We firstly proposed the concept of the academic standards of the modern basic theory of traditional Chinese medicine and its logical structure and standards points in this paper. According to the research progress at home and abroad, we explored the basic concept of academic, academic standards, academic of Chinese medicine, academic standards of Chinese medicine in depth, given the logical definition of relevant concepts, and revealed the connotation and logical hierarchy relationship between different concepts. On this basis, we proposed three-level standards points of the academic standards of Chinese medicine. All of these works mentioned above would provide a preliminary standards protection for the academic research of traditional Chinese medicine and the establishment of the modern basic theory of traditional Chinese medicine.

OBJECTIVETo summarize the clinical features of idiopathic hypogonadotropic hypogonadism (IHH) diagnosed during childhood, and detect mutations in KAL1 and FGFR1, acting as key clues for diagnoses.

METHODWe collected and analyzed clinical data of 21 cases (including demographic data, chief complaint, history of present illness, family history, physical examination, laboratory tests and imaging studies, etc.) diagnosed with IHH from December 2008 to February 2013. Polymerase chain reaction and gene sequencing was applied to detect mutations on KAL1 and FGFR1. Fifty healthy unrelated individuals were choosen as controls.

RESULTOf 21 patients with IHH, 19 were males and 2 females, they visited us initially from 8-17 years old, with an average of (13.58 ± 2.38) years old. Sixteen cases were KS patients (76%). One boy reported abnormal sense of smelling but having olfactory perfect picture on MRI; 2/19 male cases had no puberty when they were over 13-14 years old without abnormal external genitalia. 8/19 cases only had small penis, 8/19 had both of cryptorchidism and small penis, and the Case 2 also had hypospadias. One boy had cryptorchidism combined with a normal penis. Only 2 girls diagnosed as IHH who visited us because of no puberty signs when they were 13 and 16 years old, respectively. Other clinical manifestations included: one with gynecomastia, 2 had mental retardation, and one was deaf; one with high palatal arch; one with mirror-movement and one with left renal agenesis but normal renal function respectively. Laboratory tests showed that the basic testosterone (T) is low and with inappropriately low or normal gonadotropin hormones. The results of cases of standard human chorionic gonadotropin (HCG) test of 7 cases out of 19 male children's were normal (testosterone>1 100 ng/L), and another nine cases continued to complete the extended HCG test, and the testosterone levels of two of them (cases 6, 8) were still lower than 1 000 ng/L. Family history: the parents in 9/21 family had delayed puberty, involving only one parent in 6 families, involving both in 2 families and the other one was an uncle having micropenis with a child. Among these 21 cases, only one boy's father had hyposmia and his first emission age was 14-15 years. Eleven patients accompanied abnormal sense of smelling and the olfactory organ abnormalities on MRI, 4 had olfactory organ abnormalities on MRI while they had good smelling function self-reportedly. We got 15 samples (12 KS and 3 nIHH cases) to screen the mutation of KAL1 (14 exons) and FGFR1 (18 exons). A splicing mutation c.1062+1G>A in KAL1 is identified in case 17 with IHH. One novel heterozygous FGFR1 mutation, a single base deletion mutation on the exon 1 c.27delC is identified in case 14. This mutation causes the premature termination codons.

CONCLUSIONThis pilot research showed that IHH/KS diagnosis in children depends on clinical manifestation rather than gene analysis. Small penis or cryptorchidism, smelling abnormality and positive familial history may contribute to the KS/HH diagnosis. MRI of olfactory bulb acts as important proof for diagnosis of KS. Mutations in KAL1 and FGFR1 gene are not main causes of Kallmann syndrome.

OBJECTIVETo prepare the oral solution of egg yolk hepatitis B virus (HBV)-specific transfer factor (EYHBV-TF) and evaluate its immunological activity as an immune regulator against hepatitis B.

METHODSFrom hens immunized with the Hepatitis B vaccine the egg yolk was isolated to extract the specific transfer factor EYHBV-TF, and its physicochemical properties were examined. Leukocyte adhesion inhibition test (LAI) was performed to detect the immunogenic activity of EYHBV-TF. The solution of EYHBV-TF was then administered orally in normal mice, and the specific cellular immune activity induced was assayed with delayed type skin hypersensitivity test (DTH), with the non-specific immune activity assessed with immune organ index. The immune responses induced by oral EYHBV-STF solution were compared with those by EYHBV-STF injection and by different dosages (injection and oral) of porcine spleen HBV-specific transfer factor (PSHBV-STF), porcine spleen nonspecific transfer factor, and egg yolk extracts from non-immunized hens.

RESULTSThe prepared EYHBV-STF oral solution, which met the standards for biological products, could inhibit leukocyte adhesion in vitro and significantly enhance mouse foot pad swelling, demonstrating its capability of transferring antigen-specific delayed type hypersensitivity reactions to naive recipient. EYHBV-STF oral solution also significantly improved the immune organ index in mice (P<0 01) with similar effects to those caused by EYHBV-STF injections and by PSHBV-STF injection and oral solution.

CONCLUSIONOrally administered EYHBV-STF and EYHBV-STF injection both possess hepatitis B antigen-specific cellular immune activity and can significantly enhance specific cellular immune responses.
