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 explore the functional connectivity(FC)changes of hippocampus and amygdala in type 2 diabetes mellitus(T2DM)patients with erectile dysfunction(DMED),and the central pathological neural mechanisms underlying DMED.Methods 61 T2DM patients who visited Department of Endocrinology,Nanjing First Hospital,Nanjing Medical University from January 2020 to December 2021 were selected and divided into a simple T2DM group(n=30)and a combined DMED group(n=31).Another 47 healthy individuals were selected as control group(NC).The international erectile function scale(IIEF-5)was used to evaluate the erectile function.Resting-state functional magnetic resonance imaging(rs-fMRI)data were acquired from all participants.MRI data were preprocessed by the DPABI software package.Bilateral hippocampus and amygdala were selected as regions of interest(ROI)and the whole brain FC values were calculated.The FC values of brain regions between groups were tested by two-sample t-test with REST software package.Results Left hippocampus as ROI:compared with the NC group,FC values of the left superior temporal gyrus increased in the T2DM group,FC values of the left superior frontal gyrus,left inferior temporal gyrus,left posterior central gyrus and rectus gyrus decreased in the DMED group.Compared with the T2DM group,FC values of the left inferior parietal gyrus,left supramarginal gyrus,left middle occipital gyrus and right posterior central gyrus decreased in the DMED group.Right hippocampus as ROI:compared with the NC group,FC values of the right middle temporal gyrus and right rolandic operculum increased while FC values of the right calcarine fissure decreased in the T2DM group;FC values of bilateral anterior cingulate gyrus,right middle temporal gyrus and left rectus gyrus decreased in the DMED group.Compared with the T2DM group,FC values of the left middle frontal gyrus,left inferior parietal gyrus and right inferior temporal gyrus decreased in the DMED group.Left amygdala as ROI:compared with the NC group,FC values in the left parahippocampal gyrus,left fusiform gyrus and right insula increased in the T2DM group;FC value of the left middle temporal gyrus decreased in the DMED group.Compared with the T2DM group,FC values of the left middle frontal gyrus and left supramarginal gyrus decreased in the DMED group.Right amygdala as ROI:compared with the NC group,FC values of the left insula,right parahippocampal gyrus,right superior temporal gyrus and right supramarginal gyrus increased while FC values in the right caudate decreased in the T2DM group;FC values of the right middle frontal gyrus,left rectus gyrus and left middle occipital gyrus decreased in the DMED group.Compared with the T2DM group,FC values of the left middle frontal gyrus and left inferior parietal gyrus decreased in the DMED group.Conclusions DMED patients have abnormalities in the hippocampus,amygdala and other brain regions,especially the frontal lobe functional cortex,which may be related to changes in their brain function.

Objective:To evaluate the effect of microvascular invasion (MVI) on postoperative prognosis of microhepatocellular carcinoma by a meta-analysis system.Methods:Relevant literatures in PubMed, Cochrane Library, Embase, CNKI, VIP and Wanfang databases were systematically searched. The search period was from January 2012 to January 2022. The Chinese search terms were "liver cancer" , "hepatocellular carcinoma" , "2 cm" , "microvascular invasion" , and "prognosis" . The English search terms were "small" , "solitary small" , "up to 2 cm" , "< 2 cm" , "liver" , "hepatocellular carcinoma" , "microvascular invasion" . The differences in prognosis of patients with microhepatocellular carcinoma in MVI(+ ) group and MVI(-) group were compared. Meta-analysis was performed using Review Manager 5.4 software.Results:Finally, 7 articles were included in the systematic review, with a total of 1 319 patients. All included literatures were scored ≥7 on the modified Newcastle-Ottawa scale. The results of meta-analysis showed that there were no significant differences in 1-year overall survival (OS) between MVI(+ ) group and MVI(-) group ( OR=3.14, 95% CI: 0.92-10.72, P=0.068). The 5-year OS time of patients in the MVI(+ ) group was shorter than that in the MVI(-) group, and the differences were statistically significant ( OR=2.34, 95% CI: 1.62-3.36, P<0.001). The 1-year and 5-year disease-free survival of the MVI(-) group were better than those of the MVI(+ ) group, and the difference was statistically significant (1-year: OR=3.09, 95% CI: 1.75-5.44, P<0.001; 5 years: OR=1.76, 95% CI: 1.24-2.51, P=0.002). Conclusion:The 5-year and long-term survival of MVI(+ ) patients with microhepatocellular carcinoma was poor, and the postoperative recurrence rate was high.

Objective:To evaluate the effect of tutorial system for medical undergraduates in a non-affiliated hospital of a medical university in Jiangsu.Methods:32 senior medical undergraduates in non-affiliated hospitals were divided into two groups. The experimental group adopted tutor-guided teaching, and the control group adopted traditional teaching. Professional theoretical knowledge, clinical ability, operational ability, foreign language level, basic research ability and participation of scientific research activities of students in the two groups were evaluated. SPSS 19.0 was used for t test, chi-square test and U test. Results:The results of operational ability ( t=3.537, P=0.000), the number of papers that had been read ( t=6.961, P=0.000), quality of these ( U=68.000, P=0.017), the number of literature reviews that had been written and reading notes ( χ2=4.747, P=0.000), participation in scientific research activities ( t=6.788, P=0.009) of students in the experimental group were better and higher than those in the control group. In the same period, there was no significant difference between the two groups in the scores of theoretical exam, clinical competence and foreign language tests. Conclusion:The implementation of tutorial system for medical students in non-affiliated hospitals is an effective measure to improve the quality of training. We should make full use of the short intership, to improve the comprehensive quality of students by establishing perfect rules, regulations and teaching evaluation system, and educate students in accordance with their own ability.

Objective To study the impact of adjuvant transarterial chemoembolization (TACE)after curative resection for patients with hepatocellular carcinoma (HCC) and microvascular invasion (MVI).Methods PubMed,Cochrane library,Embase,Web of Science,CNKI,VIP,Wanfang were searched for randomized or non-randomized studies which compared recurrence-free survival and overall survival rates with or without postoperative adjuvant TACE after curative resection for patients with HCC and MVI.The limited search time was from January 1st,1999 to May 1st,2019.Statistical analyses were performed with software programs using Stata (version 15.0) and Review Manage (version 5.3).Results Eight studies which included 1 809 patients were studied.There were 815 patients who received and 994 patients who did not receive postoperative adjuvant TACE after radical hepatectomy.Postoperative adjuvant TACE significantly improved recurrence-free survival and overall survival rates in patients with HCC and MVI when compared with the patients who required no adjuvant TACE (HR =0.74,95％ CI:0.65-0.85,P ＜0.05;HR =0.74,95％ CI:0.62-0.89,P ＜ 0.05,respectively).Subgroup analysis demonstrated that patients with tumor diameter ＞ 5 cm benefited from postoperative adjuvant TACE only in recurrence-free survival rate (HR =0.72,95％ CI:0.58-0.90,P ＜ 0.05),but not in overall survival rate.Conclusion Postoperative adjuvant TACE delayed recurrence of microvascular invasion of HCC and improved long-term prognosis,but not for tumors with diameter ＞5 cm.These results need to be validated in further clinical trials.

ObjectiveTo investigate the optimal cut-off value of alpha-fetoprotein (AFP) in the diagnosis and early screening of hepatocellular carcinoma (HCC). MethodsThe clinical data of 2212 HCC patients who were diagnosed and hospitalized in our hospital and 1998 non-HCC patients were collected, and the AFP level was summarized. The AFP level was divided into 10 ranges of 10-20 μg/L, 21-65 μg/L, 66-110 μg/L, 111-155 μg/L, 156-200 μg/L, 201-250 μg/L, 251-300 μg/L, 301-350 μg/L, 351-400 μg/L, and ＞400 μg/L, and a comparative analysis was performed for the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio of each cut-off value of AFP, ultrasound, and their combination in the diagnosis of HCC. The receiver operating characteristic (ROC) curve was plotted to determine the optimal cut-off value. ResultsThe cut-off valve of AFP of 200-250 μg/L had the largest sum of sensitivity and specificity (1.370 1) and the largest area under the ROC curve (0.896 4). AFP ＞20 μg/L combined with ultrasound had the highest sensitivity (95.35%) in the diagnosis of HCC, with a diagnostic odds ratio of 26.13. ConclusionThe optimal cut-off value of AFP in the diagnosis of HCC is 200 μg/L. When AFP combined with ultrasound is used for the screening of people at a high risk of HCC, AFP＞20 μg/L is recommended as a positive index, and its combination with differential diagnosis and close follow-up and examinations can reduce the false negative rate of screening.

Objective To investigate the impact of combined postoperative transcatheter arterial chemoembolization (TACE) with antiviral therapy in hepatitis B-related hepatocellular carcinoma (HBV-HCC) patients with high risks of recurrence.Methods Fifty-three consecutive patients who underwent curative resection of HBV-HCC between January 2014 to February 2016 were enrolled.These patients were assigned to either the adjuvant antiviral therapy combined with TACE group (n =32),the treatment group or the no adjuvant treatment group (n =21,the control group).The recurrence-free survival (RFS) and overall survival (OS) were analyzed.Results There was no significant difference between the two groups in clinical characteristics (P＞0.05).The recurrence-free survival (RFS) (mean±S.D.) was (20.1 ± 1.8) months in the treatment group and (18.7±2.4) months in the control group (P=0.752).The 1-,2-and 3-year RFS rates of the treatment group and the control group were 65.6％ vs.57.1％,31.3％ vs.28.6％ and 15.6％ vs.14.3％,respectively (P＞0.05).The overall survival (OS) (mean±S.D.) was (26.8± 1.7) months in the treatment group and (21.1±2.2) months in the control group (P=0.037).The 1-,2-and 3-year RFS rates were 65.6％ vs.57.1％,31.3％ vs.28.6％ and 15.6％ vs.14.3％ in the treatment group and the control group,respectively.The 1-,2-,and 3-year OS rates were 87.5％ vs.66.7％,59.4％ vs.38.1％ and 43.8％ vs.19.0％ in the treatment group and the control group,respectively.Conclusion Antiviral therapy in combination with TACE did not decrease the RFS rate,but it improved the OS rate in HCC patients with high risks of recurrence.

The high incidence of postoperative recurrence of hepatocellular carcinoma ( HCC) is a most difficult obstacle for improving the prognosis of patients.Several adjuvant modalities have been developed to prevent recurrence in patients after surgery; nevertheless , there is no consensus regarding the standardized adjuvant therapy in terms of indications , clinical efficacy and interactions.In this article we review the currently available evidence in the medical literature on adjuvant therapy in HCC after radical resection.

Objective To compare the long-term efficacy between laparoscopic liver resection and open liver resection to treat small hepatocellular carcinoma.Methods The clinical data of 52 patients with small hepatocellular carcinoma treated from August 2011 to November 2012 were reviewed.Twenty patients underwent laparoscopic liver resection (the laparoscopic group),while the remaining 32 patients underwent open liver resection (the laparotomy group).The preoperative,postoperative and overall survival data between the two groups were compared.Results The data between the two groups before surgery were comparable (all P ＞ 0.05).The differences in tumor size and pathologic type between the two groups did not reach statistical significance (t =1.087,x2 =0.738,all P ＞ 0.05).However,the length of hospital stay in the laparoscopic group was significantly shorter than in the laparotomy group (t =3.363,P ＜ 0.05).Post-procedural complications occurred in no patients in the laparoscopic group,but in 8 patients in the laparotomy group (x2 =5.909,P ＜ 0.05).The cumulative survival rates in the two groups were not statistically signifi cant (P ＞ 0.05),but the recurrence-free survival of the laparoscopic group was significantly longer than the laparotomy group (P ＜ 0.05).The postoperative 1-year disease-free survival was not significantly different (P ＞ 0.05),though the 3-and 5-year recurrence-free survival rates were significantly different (all P ＜ 0.05).Conclusion The long-term overall survival rate of laparoscopic treatment for small liver cancer was similar to open operation,but the recurrence free survival rate was greatly improved.
