Objective:The establish a standardized training assessment indicator system for young teachers in medical colleges and universities, and to improve the quality of training.Methods:A preliminary assessment indicator system was established through literature analysis and small-sample expert interviews, and then the Delphi method was used to conduct consultation with 40 experts familiar with the standardized training of young teachers in medical colleges and universities. The assessment indicator system was modified based on the opinions of the experts, and consultation was conducted again until basically consistent opinions were obtained from the experts. The analytic hierarchy process was used to assign weights to each indicator, and SPSS 17.0 was used for data analysis and processing.Results:After two rounds of expert consultation, 35 experts agreed with each indicator at a rate of more than 90%, and their opinions were basically consistent. The weight variation coefficient (W value) of each indicator ranged from 0.00 to 0.15, indicating a high degree of concentration. Finally, a standardized training assessment indicator system was established for young teachers, which consisted of 4 first-level indicators, 11 second-level indicators, and 35 third-level indicators.Conclusions:This assessment indicator system provides a basis for scientific evaluation of the quality of standardized training for young teachers in medical colleges and universities and improves the quality and efficiency of standardized training for young teachers by "promoting construction through evaluation and promoting supervision through evaluation".

College students shoulder the heavy responsibility of the times and are the key to improving the quality of the peo-ple.The strategic goal of"Healthy China"has put forward higher requirements for general education courses in universities.Immunity and Health is a general education course offered by Shandong University for the entire school.While optimizing teaching content in the classroom to achieve knowledge goals,it guides students to think about the emotional value behind knowledge,improve immune intel-ligence,and thus achieve the mission of cultivating talents for the construction of a"Healthy China".This article explores the develop-ment process of the teaching mode of"Immunity and Health",which has important practical significance for enhancing general educa-tion in universities and promoting the purpose of"advocating a healthy and civilized lifestyle,shaping self-discipline and healthy behavior"in China.

Background and purpose:Currently,for patients with mid-to-low locally advanced rectal cancer and potentially resectable T4bM0 colon cancer,guidelines recommend neoadjuvant therapy strategies to enhance the response rate and increase the likelihood of conversion surgery.Among these patients,ypⅢ stage colorectal cancer(CRC)is assessed using the Union for International Cancer Control(UICC)/American Joint Committee on Cancer(AJCC)TNM staging system for postoperative pathological features.However,neoadjuvant therapy can lead to lymph node regression in the surgical area,resulting in an insufficient number of detected lymph nodes(less than 12),preventing classification according to conventional TNM staging.Thus,TNM staging often fails to predict the prognosis of ypⅢ patients who have undergone neoadjuvant therapy.This study aimed to evaluate the prognostic value of the positive lymph node ratio(LNR)in ypⅢ stage CRC patients treated with neoadjuvant therapy.Methods:Retrospective data was collected from ypⅢ stage CRC patients who received neoadjuvant therapy and underwent radical surgery at Fudan University Shanghai Cancer Center between 2008 and 2018.Collect clinical pathological characteristics such as age,gender,primary tumor location,tumor differentiation grade,pathological staging,and whether the patient has relapsed or died during follow-up at the time of surgery.Inclusion criteria:CRC patients who have received neoadjuvant therapy and surgery and have been confirmed to be stage Ⅲ by postoperative pathological examination.Exclusion criteria:① Preoperative imaging examination or intraoperative exploration reveals distant organ metastasis;② History of malignant tumors in the past;③ Multiple primary CRC.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(ethics number:050432-4-2108*).The R software survminer package(surv_cutpoint algorithm)was used to calculate the optimal cutoff value for LNR relative to disease-free survival(DFS),and patients were divided into low and high LNR groups accordingly.Clinical pathological characteristics and DFS were compared between the two groups.COX proportional hazards regression models were employed to identify adverse pathological features,and survival plots along with prediction models for DFS were generated using the survival and rms packages.Results:A total of 489 patients were included,comprising 289 males and 200 females,with a median age of 56 years(23-80 years)and a median follow-up time of 1 062 d.During the follow-up period,164 patients(33.5%)died.In the entire cohort,204(41.7%)patients had fewer than 12 lymph nodes detected.The optimal cutoff value for LNR was 0.29,classifying 317 patients into the low LNR group(LNR≤0.29)and 172 patients into the high LNR group(LNR＞0.29).The high LNR group exhibited shorter DFS compared to the low LNR group[hazard ratio(HR)=2.103,95%CI:1.582-2.796,P＜0.000 1].Multivariate COX regression indicated that LNR was an independent prognostic factor for DFS(HR=1.825,95%CI:1.391-2.394,P＜0.001).The inclusion of LNR in a multicategory DFS nomogram prediction model effectively assessed DFS in stage Ⅲ CRC patients who had undergone neoadjuvant therapy.Conclusion:LNR is an independent prognostic factor for ypⅢ stage CRC patients,showing good predictive power for DFS when combined with other adverse pathological features.Therefore,incorporating LNR as a supplement to TNM staging can improve the accuracy of CRC prognosis assessment.

BACKGROUND:Previous studies have reported inconsistent results with positive,negative,and J-shaped associations between alcohol consumption and the hazard of aortic aneurysm and dissection(AAD).This study aimed to examine the connections between weekly alcohol consumption and the subsequent risk of AAD. METHODS:The UK Biobank study is a population-based cohort study.Weekly alcohol consumption was assessed using self-reported questionnaires and the congenital risk of alcohol consumption was also evaluated using genetic risk score(GRS).Cox proportional hazards models were used to estimate hazard ratios(HRs)with 95%confidence intervals(CIs)for the associations between alcohol consumption and AAD.Several sensitivity analyses were performed to assess the robustness of the results. RESULTS:Among the 388,955 participants(mean age:57.1 years,47.4%male),2,895 incident AAD cases were documented during a median follow-up of 12.5 years.Compared with never-drinkers,moderate drinkers(adjusted HR:0.797,95%CI:0.646-0.984,P<0.05)and moderate-heavy drinkers(adjusted HR:0.794,95%CI:0.635-0.992,P<0.05)were significantly associated with a decreased risk of incident AAD.Interaction-based subgroup analysis revealed that the protective effect of moderate drinking was reflected mainly in participants younger than 65 years and women. CONCLUSION:Our findings support a protective effect of moderate alcohol consumption on AAD,but are limited to participants younger than 65 years and women.
