Kidney transplantation is the most ideal treatment method for end-stage renal disease, significantly improving the survival rate and quality of life of patients. However, as the postoperative survival period gradually lengthens, chronic diseases have become the main obstacle affecting the long-term outcome of kidney transplantation. These chronic diseases have a high incidence, involve multiple organs and significantly impact prognosis. The core driving factors are mainly related to long-term immunosuppressive therapy. This article systematically discusses the occurrence mechanisms, prevention and treatment strategies, and classification management of common chronic diseases after kidney transplantation (mainly including chronic graft dysfunction, cardiovascular diseases, infections, malignant tumors, bone metabolism disorders, etc.). At the same time, it explores future development directions such as precision medicine, new immune modulators and remote management, emphasizing a comprehensive management model centered on "multidisciplinary collaboration + individualized treatment + continuous monitoring" to achieve long-term, systematic, and dynamic prevention and treatment of chronic diseases for kidney transplant recipients.

Since the founding of the People’s Republic of China, remarkable achievements have been gained in infectious disease prevention and control, and rich practical experiences have been accumulated. If these experiences are shared with developing countries, it will greatly contribute to global infectious disease control and global health security. Under the framework of Forum on China-Africa Cooperation, a series of China-Africa public health capacity training programs have been recently held in China, in order to help improve the capability of infectious disease control in African countries. This article summarized and refined good design concepts and practices from these programs, so as to provide insights into sustainable optimization of China-Africa public health capacity training and improvements of the training effectiveness.

Background: and Purpose Live cell-based assays (LCBA) are increasingly used for serological antibody detection due to their ability to preserve antigen conformation, offering moderately higher sensitivity than fixed cell-based assays. However, the clinical necessity of prioritizing LCBA for the detection of aquaporin-4 immunoglobulin G (AQP4-IgG) in neuromyelitis optica spectrum disorder (NMOSD) remains unclear, especially when compared to its established role in diagnosing myelin oligodendrocyte glycoprotein antibody-associated disease. Methods: We compared the performance of live cell-based assays using immunofluorescence (LCBA-IF) and fixed cell-based assays using immunofluorescence (FCBA-IF) in detecting AQP4-IgG in 90 cases of NMOSD meeting 2015 International Panel for Neuromyelitis Optica Diagnosis criteria, alongside 40 controls. Additionally, we further investigated the relationship between AQP4-IgG titers as measured by LCBA-IF and FCBA-IF and clinical parameters in NMOSD patients. Results: Results showed 96.9% agreement between LCBA-IF and FCBA-IF (Cohen’s κ=0.935), with a strong Spearman correlation (0.977, p<0.001). Both methods demonstrated 100% specificity, with LCBA-IF showing slightly higher sensitivity compared to FCBA-IF. Within LCBAIF-tested groups, statistically significant differences in annualized relapse rates were observed across all pairwise comparisons (low-titer vs. moderate-titer, low-titer vs. high-titer, and moderate-titer vs. high-titer; all p<0.050). However, this association reached statistical significance in some FCBA-IF-tested groups. Conclusions Overall, there is a strong concordance between LCBA-IF and FCBA-IF in detecting AQP4-IgG, where LCBA-IF shows slightly higher sensitivity. Furthermore, there is a potential link between elevated AQP4-IgG titers and an increased risk of relapse, and this correlation may appear more pronounced when using LCBA-IF.

Ulcerative colitis （UC） is a chronic nonspecific inflammatory intestinal disease with a complex pathogenesis. Its recurrent attacks easily lead to persistent intestinal mucosal damage， resulting in a year-by-year increase in incidence and imposing a heavy burden on patients. Currently， the treatment of UC mainly relies on corticosteroids， immunosuppressants， and aminosalicylate preparations. However， these therapies are limited by significant side effects， strong drug resistance， and poor long-term prognosis. As one of the important inflammatory pathways， the Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway can regulate the occurrence and development of UC through multiple pathways by modulating multiple downstream targets. Therefore， the JAK2/STAT3 signaling pathway offers a new research direction for the treatment of UC. Numerous studies have shown that the JAK2/STAT3 signaling pathway plays an important role in intestinal inflammatory responses， intestinal mucosal barrier damage， T helper cell 17 （Th17）/regulatory T cell （Treg） immune imbalance， intestinal epithelial cell apoptosis， and oxidative stress. Chinese medicine has attracted increasing attention because of its unique advantages， including fewer side effects， individualized diagnosis and treatment， and enhancement of efficacy with reduction of toxicity. In addition to traditional Chinese herbal formulas， more Chinese medicine monomers and extracts have played key roles because of their more precise therapeutic targets. In recent years， many studies have confirmed that Chinese medicine can exert therapeutic effects on UC by interfering with the JAK2/STAT3 signaling pathway， thereby alleviating intestinal inflammatory responses， repairing the intestinal mucosal barrier， regulating the balance of Th17/Treg immune cells， inhibiting intestinal epithelial cell apoptosis， and suppressing oxidative stress. This article summarizes and reviews recent research progress in this field from three aspects， including an overview of the JAK2/STAT3 signaling pathway， the relationship between the JAK2/STAT3 signaling pathway and UC， and the regulatory mechanisms of traditional Chinese medicine， with the aim of providing a theoretical basis for the future clinical treatment of UC and drug development.

AIM:To analyze differential proteins associated with the pathogenesis of dry eye(DE)using bioinformatics methods, in order to reveal their potential molecular mechanisms.METHODS: Articles published in PubMed and EMBASE databases from the inception of the database to August 31, 2023, that used proteomic methods to detect protein expression in clinical samples of dry eye were searched. Differential proteins were selected and further analyzed using the STRING database and Cytoscape software for hub gene screening and module analysis. Protein-protein interaction(PPI)analysis, gene ontology(GO)functional annotation, and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis were performed.RESULTS: A total of 21 articles were included, identifying 74 differentially expressed proteins. The most frequently occurring differential proteins were calgranulin A(SA1008), lipocalin-1(LCN1), lysozyme C(LYZ), mammaglobin-B(SCGB2A1), proline-rich protein 4(PRR4), transferrin(TF), and calgranulinB(S100A9). The top 10 hub genes were serum albumin(ALB), tumor necrosis factor(TNF), interleukin 6(IL6), IL1B, IL8, matrix metalloproteinase 9(MMP9), alpha-1-antitrypsin(SERPINA1), IL10, complement component 3(C3), and lactotransferrin(LTF). Module analysis suggested MMP9 and PRR4 as seed genes. KEGG analysis showed that differential proteins were mainly enriched in the IL17 signaling pathway(61.9%).CONCLUSION: The results reveal potential molecular targets and pathways for DE and confirm the association between the pathogenesis of DE and inflammation. Further in-depth research is needed to confirm the significance of these biomarkers in clinical practice.

Objective: To investigate the feasibility of magnetic anastomosis for uretero-ileal anastomosis using experimental rabbit models. Methods: Six experimental rabbits were used as the models.The lower part of the left ureter was cut with scissors，the daughter magnet (DM) was placed in the middle of the ureter，and the distal end of the ureter was ligated.After that，the ileum wall was opened，the parent magnet (PM) was inserted through it，the positions of the PM and DM were adjusted so that their ends were attracted to each other，and then ileum wall incision was sutured.The operation time，intraoperative blood loss，postoperative complications and magnet discharge time were recorded.Two weeks after operation，left ureterography was performed to obtain the specimens of the uretero-ileal anastomosis，and to observe the patency of the anastomosis.The formation of the anastomosis was observed with naked eyes and light microscope. Results: Uretero-ileal magnetic anastomosis was performed successfully in 6 experimental rabbits.The operation time was 28-39（32.50±3.94） min，and the intraoperative blood loss was less than 5 mL.The rabbits recovered well after operation，and no complications were observed.All animals survived to the end point of observation.The disconnection time of magnet after operation was 9-13(10.83±1.72) days.The gross specimen showed that the anastomosis was patent.The histological observation showed that the mucosa of the anastomosis was continuous and smooth，and the anastomosis was well formed. Conclusion: Magnetic anastomosis is feasible for uretero-ileal anastomosis with simple operation and good anastomosis formation.After further experimental verification，this technique is expected to be used in clinical practice.
