Nephroptosis,a rare condition in urology,often results from inadequate support of the kidney's perinephric fat structures,leading to excessive renal mobility.It typically occurs in lean,tall,young females.Some cases manifest with abdominal pain and renal dysfunction.Open nephropexy,laparoscopic nephropexy and percutaneous nephropexy are all effective methods in the treatment of nephroptosis,among which percutaneous nephropexy is associated with less trauma and lower costs.Modifications to percutaneous nephropexy by the authors'team are also introduced mentioned in this article.

Objective:To construct evaluation indicators for the effectiveness of curriculum ideology and politics education in medical colleges and universities based on the Center for the Study of Evaluation (CSE) model.Methods:Based on the CSE-based theoretical framework of "needs evaluation, program evaluation, formative evaluation, and summative evaluation", semi-structured interviews were conducted to select indicators. The Delphi method was used to conduct two rounds of questionnaire-based consultation with 29 experts to establish a set of indicators for evaluating the effects of curriculum ideology and politics teaching of medical colleges and universities. The priority diagram was used to calculate and determine the weight of each index.Results:The authority coefficient of the 29 experts included in this study was 0.85. The Kendall's coefficients of concordance for the two rounds of expert consultation were 0.361 and 0.577 ( P<0.05), respectively. Finally, an evaluation system for the effectiveness of curriculum ideology and politics teaching was formed, including 4 first-level indicators, 9 second-level indicators, and 18 evaluation observation points. The 4 first-level indicators were "implementation objectives", "implementation plans", "implementation process", and "implementation effects". Conclusions:The CSE model is suitable as a theoretical framework for constructing the evaluation system of curriculum ideology and politics teaching in medical schools, which employs scientific indicator construction methods, follows the basic principles of course evaluation, and conforms to the current concept of ideological and political construction of medical curricula, showing certain feasibility and guiding significance.

Objective:To construct a scientific and systematic indicator system for the ideological and political construction of medical professional courses in military medical universities, and to provide a reference for the teaching management department of military medical universities to guide and manage the ideological and political construction of courses, as well as for medical professional course instructors to carry out the ideological and political teaching of courses.Methods:On the basis of literature research and case studies, a framework of the indicator system was established for the ideological and political construction of medical professional courses in military medical universities, and six experts in the field of military medical education were invited for pre-consultation. A preliminary draft of the indicator system was formed after discussion within the research group. A total of 25 experts, who had intermediate or above professional titles and long-term experience in military medical education, teaching and management, military academy education management, and military ideological and political education in military academies, were invited to conduct two rounds of Delphi expert consultation, and a statistical analysis was performed for the consultation results to determine the indicator system for the ideological and political construction of medical professional courses in military medical universities. The percentage weight method and the product method were used to calculate the weight coefficient of each indicator and combined weight coefficient.Results:In the two rounds of expert consultation, the expert positivity coefficient was 100%, the expert authority coefficient was 0.883, and the Kendall harmony coefficients were 0.254 and 0.268, respectively ( P<0.05). Finally, an indicator system was established for the ideological and political construction of medical professional courses in military medical universities, which consisted of 5 primary indicators, 12 secondary indicators, and 31 tertiary indicators. The 5 primary indicators were the teaching objectives, teaching team, teaching resources, teaching implementation, and teaching effect of curriculum ideology and politics, with a weight coefficient of 0.210, 0.202, 0.197, 0.202, and 0.189, respectively. Conclusions:The indicator system constructed in this study is scientific, reliable, systematic, and comprehensive and has a certain guiding significance for the ideological and political construction of medical professional courses in military medical universities.

Objective:To investigate the perioperative safety and survival benefits of two-stage operation in the treatment of esophageal malignancies.Methods:This is a retrospective case series study. The clinical data of 70 patients who underwent two-stage operation for esophageal malignancies from January 2015 to January 2023 in the Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. There were 58 males and 12 females. The age ( M(IQR)) was 61 (22) years (range: 9 to 79 years), and 51.4% (36/70) of the patients were older than 65 years. All patients underwent the first operation to remove esophageal tumor and the second operation to complete digestive tract reconstruction. The reasons for two-stage operation were summarized, complications and treatment results were recorded, and the prognosis was calculated using Kaplan-Meier curve. Results:The interval between the two stages was 49 (35) days (range: 32 to 82 days). The follow-up perrod was 28(50) months (range: 1 to 69 months). The 30-day fatality rate after the first operation was 4.3% (3/70) and the 30-day fatality rate after the second operation was 0(0/63). The total complication rate of first operation was 55.7% (39/70), the respiratory complication rate was 10.0% (7/70) and the cardiovascular complication rate was 5.7% (4/70) The incidence of anastomotic leakage was 11.1% (9/63). The overall survival rate at 2, 3 and 5 years was 35.7%, 30.0% and 15.7%, respectively.Conclusion:Two-stage operation in the treatment of complex esophageal malignancies is feasible and yields satisfaetory results.

Mycoplasma pneumoniae is the most common pathogen of respiratory tract infection in children and adults. Clinical observation shows that M. pneumoniae infection can cause massive mucus secretion in the respiratory tract, which makes the breathing of patients difficult. Studies have shown that M. pneumoniae infection can cause massive secretion of mucin 5AC (MUC5AC). Adhesin P1 plays an important role in the pathogenesis of M. pneumoniae infection by mediating the adhesion of pathogens to host cells, and the C-terminal residues of P1 (P1-C) are immunogenic. This study investigated the molecular mechanism of Wnt/β-catenin signaling pathway inhibitor Dickkopf-1 (DKK1) in the secretion of MUC5AC in mouse airway epithelial cells (MAECs) induced by P1-C. Scanning electron microscope and hematoxylin-eosin staining were used to observe the effect of P1-C on mucus secretion of MAECs. Protein chip was used to detect the secretion of cytokines and analyse the enrichment of related signaling pathways induced by P1-C in MAECs. Periodic acid schiff stain (PAS) staining, Tunel staining and Masson staining were used to detect the damage of the lungs of mouse exposed to P1-C. Immunohistochemistry was used to detect the secretion of MUC5AC expression, and Western blotting was used to reveal the molecular mechanism of DKK1-regulated secretion of MUC5AC induced by P1-C protein in MACES. The results showed that P1-C induced the massive secretion of mucus and inflammatory factors in MAECs. During P1-C infection, DKK1 down-regulated janus kinase 2 (JAK2), phosphorylation signaling and transcription activator 1 (p-STAT1) and phosphorylation signaling and activator of transcription 3 (p-STAT3) expression. Overexpression of DKK1 significantly up-regulated the expression of MUC5AC repressor transcription factor fork-head box protein A2 (FOXA2). At the same time, the expression of MUC5AC induced by P1-C was inhibited significantly. It is speculated that DKK1 can effectively reduce the secretion of MUC5AC in MAECs induced by P1-C by inhibiting the JAK/STAT1-STAT3 signaling pathway and up-regulating the expression of FOXA2.

The ideological and political construction of medical courses reveals the educational essence of "truth, goodness, and beauty" in medicine. Scientificity and humanity are the embodiment of "seeking truth" and "advocating goodness" in medicine, and the unity of their content and form reaches the highest level of "advocating beauty". Studying the ideological and political construction of medical courses plays an important role in implementing the fundamental task of fostering virtue through education, and carrying out the Healthy China initiative. In terms of teaching objectives, the goals of ideological and political education in medical courses should not only include the goals of basic literacy goals, such as political literacy, cultural literacy, legal literacy, and moral cultivation, but also include professional literacy goals, such as medical humanistic cultivation. Thus, a "five in one" model of ideological and political education in medical courses will be established. In the practical path, it is suggested to explore from five aspects that changing the educational concept and strengthening the educational awareness, establishing teaching objectives and clarifying education direction, digging deeply into the ideological and political elements and clearing teaching content, innovating teaching methods and improving teaching effectiveness, and constructing evaluation indicators and evaluating teaching effectiveness scientifically.

By means of analysis of related national policies on medical alliances, and investigation of their current development in China, the authors summarized the conceptual category of existing medical alliances. Typical cases were selected for comparative analysis in terms of urban medical groups, medical communities, specialized alliances and telemedicine collaboration networks. In view of such setbacks found as lack of health services, ambiguity of power and duties of stakeholders, and low penetration rate of composite medical insurance payment, as well as lack of effective incentives and poor online diagnosis and treatment mechanism, the authors recommended on development of medical alliances in respect of framework improvement and mechanism optimization among others.
