Objective To explore the efficacy and safety of treatment of intramural ureteral tumors via transurethral resection. Methods A retrospective analysis was conducted on the clinical data of 26 patients with ureteral cancer who underwent transurethral resection of intramural ureteral tumors at the First Affiliated Hospital of Naval Medical University from May 2020 to May 2023. All patients were treated using the “outer-wedge, inner-rotation” resection technique, with ureteral stents placed intraoperatively. Clinical indicators including operation time, intraoperative blood loss, length of postoperative hospital stay, ureteral stent indwelling duration, intraoperative and postoperative complications, postoperative pathological results, and bladder tumor recurrence rate were analyzed. Results All surgeries were successfully completed. The operation time was 45(35, 60) min, intraoperative blood loss was 5(3, 10) mL, length of postoperative hospital stay was 4(3, 5) d, and the ureteral stent indwelling duration was (33.8±9.7) d. All patients did not experience intraoperative complications, the postoperative hydronephrosis rate was 3.8%. Postoperative pathology confirmed urothelial carcinoma in all cases, including 6 cases of stage pT_a, 16 cases of pT₁, and 4 cases of pT_2a. The follow-up period ranged from 12 to 48 months. Intravesical recurrence occurred in 2 patients, and recurrence rate was 7.7%. There were no tumor-related deaths during the follow-up period. Conclusions Transurethral resection of intramural ureteral tumors is minimally invasive, resulting in less blood loss, and has low rates of postoperative complications such as hydronephrosis and hydroureter. It achieves favorable surgical outcomes while better preserving renal function.

Neoadjuvant therapy has become the standard treatment for locally advanced resectable esophageal cancer, significantly improving long-term survival compared to surgery alone. Neoadjuvant therapy has evolved to include various strategies, such as concurrent chemoradiotherapy, chemotherapy, immunotherapy, or targeted combination therapy. This enriches clinical treatment options and provides a more personalized and scientific treatment approach for patients. This article aims to comprehensively summarize current academic research hot topics, review the rationale and evaluation measures of neoadjuvant therapy, discuss challenges in restaging methods after neoadjuvant therapy, and identify the advantages and disadvantages of various neoadjuvant therapeutic strategies.

AIM:To explore the mechanism of ac-tion and clinical significance of NLRC4 in multiple myeloma by analyzing the relative expression and clinical significance of NLRC4 mRNA in bone mar-row fluid of patients with multiple myeloma(MM),so as to guide the formulation of disease treatment and the evaluation of clinical prognosis.METHODS:MMRF database and GTEx database were used to compare the expression and survival correlation of inflammatory bodies between myeloma patients and normal controls.Real-time fluorescent quanti-tative polymerase chain reaction(qPCR)was used to detect the expression of inflammatory bodies in bone marrow fluid of 26 newly diagnosed myeloma patients and 19 post-treatment myeloma patients and peripheral blood of 28 normal volunteers ad-mitted to the First Affiliated Hospital of Anhui Medi-cal University from January to September 2023.The mRNA expression differences of each inflammatory body and the correlation between NLRC4 inflamma-tory body expression and clinicopathologic fea-tures,inflammatory factor/chemokine expression of newly diagnosed patients were analyzed.RE-SULTS:Compared with the control group and the treatment group,the expression of inflammasome mRNA in the newly diagnosed group was increased except for NLRP3,and the expression of NLRC4 mRNA was significantly increased(P<0.01).The he-moglobin count,creatinine level and calcium ion level were linearly correlated with NLRC4 mRNA ex-pression level in newly diagnosed patients(P<0.05).The mRNA expression levels of IL-18,CCL-3 and NL-RC4 in newly diagnosed patients were linearly cor-related(P<0.05).CONCLUSION:NLRC4 inflammato-somes are highly expressed in MM,and promote the occurrence and development of tumor by pro-moting the production and release of inflammatory cytokines/chemokines IL-18 and CCL-3,which is of great significance for the formulation of treatment plan and clinical prognosis evaluation of multiple myeloma.

Objective:To explore the effect of the Nurse-Mini-CEX assessment method combined with PBL teaching mode in the cultivation of core competencies of undergraduate nursing students during ICU internships.Methods:A total of 64 nursing students interning in the ICU of a Third-grade Class-A hospital in Wuhu City from Sep 2022 to Aug 2023 were selected and randomly divided into 8 groups(8 students in each group).Using cluster sampling,4 groups(32 students)were assigned to the experimental group,receiving training via Nursing-Mini-CEX combined with PBL,while the remaining 4 groups(32 students)served as the control group,undergoing traditional clinical teaching.All students completed a 2-month pre-ICU clinical internship,followed by a 4-week ICU internship.Results:Compared to the control group,the experimental group showed significantly higher scores in five dimensions of nursing competency:nursing consultation,nursing physical examination,nursing diagnosis,nursing interventions,and holistic evaluation(P＜0.05).Additionally,the experimental group outperformed the control group in core competencies,including clinical nursing skills,leadership,interpersonal communication,professional development,critical thinking and research ability(P＜0.05).Self-efficacy in learning ability and behavior,as well as scores in personal accomplishment,depersonalization,and emotional exhaustion,were also higher in the experimental group(P＜0.05).Furthermore,the experimental group reported greater satisfaction with training content,teaching effectiveness,clinical skill development,teamwork cultivation,and overall satisfaction(P＜0.05).Conclusions:Nursing-Mini-CEX assessment combined with PBL teaching mode effectively enhances core competencies and self-efficacy,reduces burnout among ICU nursing interns,and achieve good clinical results,providing a theoretical and practical basis for the teaching and training of nursing students in ICU.However,as a single-center study,further validation and broader studies are warranted.

"Global cancer statistics 2022" based on the latest GLOBCAN data from the International Agency for Research on Cancer (IARC) was recently released, providing a systematic analysis of the incidence and mortality of 36 types of cancer across 185 countries worldwide. The international burden of cancer is expected to continue to increase over the next 30 years, posing a severe public health and social challenge for many countries, including China. This article offers a key point interpretation of the "Global cancer statistics 2022", focusing on the evolution of cancer epidemiology and future development trends. The aim is to broaden the international perspective on cancer prevention and treatment, with the hope of providing reference and guidance for cancer prevention and treatment efforts in our country.

Standardized reporting is a crucial factor affecting the use of patient guidelines （PGs）， particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting， including the research on PG content and presentation formats， and provided comprehensive recommendations for PG reporting from aspects such as overall framework， recommendations， presentation format， and readability. First， the presentation of PG recommendations should include clearly defined clinical questions， recommendations and their rationale， and guidance on how patients should implement the interventions； for specific content in the PG， such as level of evidence， level of recommendation， it is recommended to explain in text the reasons for giving different levels of recommendation， i.e.， to present the logic behind giving the level of recommendation to the patient； additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently， the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines （RIGHT-PVG） reporting framework. Finally， to enhance readability and comprehension， it is recommended to refer to the Patient Education Materials Assessment Tool （PEMAT） for translating PG content. To enhance the readability of PGs， it is suggested to present the PG content in a persona-lized and layered manner.

Since the concept of patient versions of guidelines （PVGs） was introduced into China， several PVGs have been published in China， but we found that there is a big difference between the concept of PVG at home and abroad， and the reason for this difference has not been reasonably explained， which has led to ambiguity and even misapplication of the PVG concept by guideline developers. By analyzing the background and purpose of PVGs， and the understanding of the PVG concept by domestic scholars， we proposed the term patient guidelines （PGs）. This refers to guidelines developed under the principles of evidence-based medicine， centered on health issues that concern patients， and based on the best available evidence， intended for patient use. Except for the general attribute of providing information or education， which is typical of common health education materials， PGs also provide recommendations and assist in decision-making， so PGs include both the patient versions of guidelines （PVG） as defined by the Guidelines International Network （GIN） and "patient-directed guidelines"， i.e. clinical practice guidelines resulting from the adaptation or reformulation of recommendations through clinical practice guidelines.

At present， the process and methodology of patient guidelines （PGs） development varies greatly and lacks systematic and standardised guidance. In addition to the interviews with PG developers， we have sorted out the relevant methodology for the adaptation and development of existing clinical practice guideline recommendations and facilitated expert deliberations to achieve a consensus， so as to finally put forward a proposal for guidance on the process and methodology for the development of PGs. The development of PGs can be divided into the preparation stage， the construction stage， and the completion stage in general， but the specific steps vary according to the different modes of development of PGs. The development process of Model 1 is basically the same as the patient version of the guideline development process provided by the International Guidelines Network， i.e.， team formation， screening of recommendations， guideline drafing， user testing and feedback， approval and dissemination. The developer should also first determine the need for and scope of translating the clinical practice guideline into a patient version during the preparation phase. Model 2 adds user experience and feedback to the conventional clinical practice guideline development process （forming a team， determining the scope of the PG， searching， evaluating and integrating evidence， forming recommendations， writing the guideline， and expert review）. Based on the different models， we sort out the process and methods of PG development and introduce the specific methods of PG development， including how to identify the clinical problem and how to form recommendations based on the existing clinical practice guidelines， with a view to providing reference for guideline developers and related researchers.
