The strategy of pelvic lymph node dissection in patients with localized intermediate- and high-risk prostate cancer（PCa）has been one of the research hotspots in recent years. This review synthesizes recent progress in clinical，diagnostic imaging and immunological aspects of pelvic lymph node dissection.It is found that the detection rate of metastatic lymph nodes in patients with localized intermediate-risk PCa is relatively low，and the survival benefit after dissection is not significant. PSMA PET/CT examination can be used instead of lymph node dissection for staging. Extended lymph node dissection in patients with localized high-risk PCa can achieve a higher detection rate of metastatic lymph nodes and possible survival benefits. However，excessive lymph node dissection can weaken the response ability to immunotherapy. The strategy for pelvic lymph node dissection in patients with localized intermediate-high-risk PCa needs further study.

[Objective] To explore the effectiveness of applying the PDCA (Plan-Do-Check-Act) cycle to enhance the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients across multiple hospital campuses. [Methods] Clinical blood transfusion data from May to July 2022 were selected. Specific improvement measures were formulated based on the survey results, and the PDCA cycle management model was implemented from August 2022. The post-intervention phase spanned from August 2022 to October 2023. The Rh phenotype compatibility rate, the detection rate of Rh system antibodies, and the proportion of Rh system antibodies among unexpected antibodies were compared between the pre-intervention phase (May to July 2022) and the post-intervention phase. [Results] After the continuous improvement with the PDCA cycle, the compatibility rate for the five Rh blood group antigen phenotypes between donors and recipients from August to October 2023 reached 81.90%, significantly higher than the 70.54% recorded during the pre-intervention phase (May to July 2022, P<0.01), and displayed a quarterly upward trend (β=0.028, P<0.05). The detection rate of Rh blood group system antibodies (β=-9.839×10^-5, P<0.05) and its proportion among all detected antibodies (β=-0.022, P<0.05) showed a quarterly decreasing trend, both demonstrating a negative correlation with the enhanced compatibility rate (r values of -0.981 and -0.911, respectively; P<0.05). [Conclusion] The implementation of targeted measures through the PDCA cycle can effectively increase the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients, reduce the occurrence of unexpected Rh blood group antibodies, thereby lowering the risk of transfusion and enhancing the quality and safety of medical care.

Objective:To compare the effectiveness and safety of in vitro fenestration and in situ fenestration for reconstruction of the left subclavian artery in patients with aortic arch diseases.Methods:A retrospective analysis was conducted on 80 patients with thoracic aortic dissection, aortic aneurysm, and aortic intramural hematoma involving the left subclavian artery at our center from Jan 2020 to Oct 2023.Results:Thirty-eight patients underwent in vitro fenestration to reconstruct the left subclavian artery, while 42 patients underwent in situ laser fenestration to reconstruct the left subclavian artery. The technical success rates were 97.4% and 97.6% respectively, without statistically significance ( P>0.05). Postoperative CTA examination showed that the primary rupture of the dissection was completely closed, 3 cases had type Ⅱ endoleak in vitro fenestration, and 2 cases had type Ⅱ endoleak in laser in situ fenestration. The blood flow inside the fenestration stent was fluent. During the perioperative period, one patient in the in vitro fenestration group experienced mild cerebral infarction (2.6%), one patient had mild paraplegia, and no related complications occurred in the other patients. Conclusion:For patients with aortic arch diseases, both in situ laser fenestration and in vitro fenestration are safe and effective.

Objective:To explore the practical effects of achieving transformative learning in students based on the "case-based+problem-oriented" teaching method for the course of "orthopedic rehabilitation".Methods:A "case-based+problem-oriented" method was introduced in clinical courses for students in the rehabilitation therapy program at Tianjin Medical University. The students in the class were randomly divided into the "case-based+problem-oriented" teaching group (56 students) and the traditional teaching group (57 students). This study compared students' exam scores for different types of theoretical questions at the end of the semester. A self-filled anonymous questionnaire survey was conducted to evaluate the effectiveness of transformative learning, including the understanding of rehabilitation theory, learning interest, doctor-patient communication ability, disease analysis and judgment ability, and rehabilitation practice ability. SPSS 20.0 was used for t test and χ2 text. Results:The "case-based+problem-oriented" teaching group achieved significantly higher scores in various types of questions and total scores compared with the traditional teaching group [(85.67±4.78) vs. (72.98±6.49), t=8.78, P=0.004)]. Students in the "case-based+problem-oriented" teaching group showed higher interest in transformative learning and a considerably increased awareness of knowledge acquisition and innovative transformation. Students in the "case-based+problem-oriented" teaching group demonstrated higher abilities in theoretical learning, communication, disease exploration, and analytical judgment in this major and course. Conclusions:The "case-based+problem-oriented" clinical transformative teaching method integrates the theoretical teaching, clinical thinking, and medical training, promotes the students' enthusiasm for learning, and improves their proactive learning of knowledge and ability to transform and innovate.

Objective To investigate the clinical value of uric acid(UA)to albumin(Alb)ratio(UAR)in predicting the prognosis of the patients with heart failure.Methods A total of 1 893 patients with heart failure and complete clinical data in the Chinese Heart Failure Database were selected as the clinical research subjects for conducting the retrospective cohort analysis.The general clinical data,coagulation routine,tropo-nin Ⅰ(cTnⅠ),cardiac enzyme profile,liver function,B-type brain natriuretic peptide(BNP),uric acid(UA)and left ventricular ejection fraction in echocardiography in the study subjects were collected to calculate UAR.Ac-cording to the receiver operating characteristic(ROC)curve,the optimal cut-off value of UAR was selected as 17.48.Then the subjects were divided into the low UAR group(UAR＜17.48,n=1 525)and high UAR group(UAR≥17.48,n=368).The clinical data were compared between the two groups,and the effect of UAR on the all-cause mortality in the patients with heart failure was evaluated by the binary logistic regres-sion analysis.Results The follow up time in the patients was 90 d,and 37 cases(2.0％)of all-cause death oc-curred during the follow up period.The proportion of males,proportion of cardiac function grade Ⅳ,propor-tion of myocardial infarction,levels of uric acid,D-dimer,creatine kinase(CK),creatine kinase isoenzyme(CK-MB),lactate dehydrogenase(LDH),alanine aminotransferase(ALT),glutamyl transpeptidase(GGT),alkaline phosphatase(AKP)and BNP in the high UAR group were higher than those in the low UAR group,while the pulse,systolic pressure,diastolic pressure,proportions of heart function grade Ⅱ and grade Ⅲ and ALB level were lower than those in the UAR group,and the differences were statistically significant(P＜0.05).The ROC curve analysis results showed that the area under the curve of UAR for assessing the all-cause death occurrence in heart failure was 0.715(95％CI:0.626-0.804,P＜0.001),the sensitivity was 56.8％and the specificity was 81.4％;the binary logistic regression analysis results showed that the incidence rate of all-cause mortality in the high UAR group was 1.09 times higher than that in the low UAR group(OR=1.09,95％CI:1.02-1.20,P=0.017).Conclusion UAR could serve as an independent predictive fac-tor of all-cause death occurrence in heart failure,which needs clinic to pay attention.
