Tertiary lymphoid structures (TLSs), as a crucial component of the tumor micro-environment, have attracted significant attention in the field of tumor research in recent years. TLSs are composed of multiple immune cells and formed under the stimulation of chronic inflammation, with their maturation process divided into different stages. They exert anti-tumor effects by mimic-king the functions of secondary lymphoid organs and generating adaptive immune responses. In terms of the prognosis of gastric cancer, the cell composition, spatial distribution of TLSs, and their combination with other indicators are all helpful in predicting the prognosis of patients. Meanwhile, the TLSs scoring system is expected to become an index for evaluating the efficacy of immuno-therapy. Treatment strategies for inducing TLSs formation have achieved certain results in animal models, but potential treatment risks require attention. The authors elaborate on formation and maturation process of TLSs, anti-tumor mechanism, value in prognostic assessment of gastric cancer and multiple tumors, prediction of immunotherapy, as well as treatment strategies for inducing the formation of TLSs.

Objective:To explore the short- and medium-term clinical outcomes of covered stent implantation in the treatment of transplant renal artery stenosis (TRAS).Methods:A retrospective analysis was conducted on the clinical data of 12 consecutive patients with TRAS (transplant renal artery stenosis) who underwent covered stent implantation in Henan Provincial People′s Hospital from January 2021 to December 2024. The changes in indicators such as serum creatinine (Cr), blood urea nitrogen (BUN), mean arterial pressure (MAP), peak systolic velocity (PSV), intrarenal resistance index (RI), and the diameter of the stenotic site were analyzed before the operation, one week after the operation, six months after the operation, and 12 months after the operation. Repeated measures analysis of variance was used to investigate the changes of each observation index over time.Results:The surgery was successfully performed on all 12 patients, with a technical success rate of 100%. Among them, 8 cases used self-expanding covered stents, and 4 cases used balloon-expandable covered stents. One week, six months and twelve months after the surgery, the levels of Cr, BUN, PSV and MAP were all lower than those before the surgery. The RI and the diameter of the stenotic site were significantly increased compared with those before the surgery, the difference was statistically significant ( P<0.05). During the perioperative period and the postoperative follow-up period, no surgery-related complications were found. Conclusion:The implantation of the covered stent can effectively relieve the stenosis of the transplant renal artery, significantly improve renal function, and reduce blood pressure levels in TRAS patients, while maintaining excellent short-to medium-term clinical outcomes.

Objective:To compare the efficacy of hip hemiarthroplasty via the fracture line approach versus modified Harding approach in the treatment of unstable intertrochanteric fractures in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 79 elderly patients with unstable intertrochanteric fractures who were admitted to Zhengzhou Orthopaedic Hospital between July 2018 and February 2024, including 17 males and 62 females, aged 80-96 years [(84.0±9.6)years]. According to the AO classification, the fractures were classified as type A2 in 61 patients and type A3 in 18. All the patients underwent hip hemiarthroplasty, 33 of whom were treated via the fracture line approach (fracture line approach group) and 46 via the modified Harding approach (modified Harding approach group). The incision length, operation duration, intraoperative blood loss, blood transfusion volume, and weight-bearing time were documented. At 1 month, 3 months after surgery and at the last follow-up, hip function and pain were assessed using the Harris hip score and visual analogue scale (VAS). Postoperative dislocation rate, fracture nonunion rate, incidence of other complications (vascular injury, neurologic impairment, prosthesis loosening, lower extremity venous thrombosis, and surgical site infection) and 12-month mortality rate were recorded.Results:All the patients were followed up for 12-36 months [(18.0±5.1)months]. The operation duration and intraoperative blood loss were (68.2±8.4)minutes and (286.6±63.7)ml in the fracture line approach group, which were significantly shorter or less than (72.4±6.7)minutes and (321.3±76.2)ml in the modified Harding approach group ( P<0.05). However, there were no statistically significant differences in the incision length, blood transfusion volume or weight-bearing time between the two groups ( P>0.05). Harris hip scores and VAS scores at 1 month, 3 months, and at the last follow-up showed no significant differences between the two groups ( P>0.05). The dislocation rate was 0 in the fracture line approach group, superior to 13% in the modified Harding approach group ( P<0.05). There were no statistically significant differences in the fracture nonunion rate, incidence of other complications, or 12-month mortality rate between the two groups ( P>0.05). Conclusion:Compared with the modified Harding approach, hip hemiarthroplasty via the fracture line approach in the treatment of unstable intertrochanteric fractures in the elderly can shorten the operation time, reduce intraoperative blood loss, and lower the postoperative dislocation rate.

The incidence of delayed chemotherapy-induced nausea and vomiting is relatively high among pediatric cancer patients. Nausea and vomiting symptoms can exacerbate physical and psychological burdens, potentially leading to aversion and reduced treatment adherence. This paper analyzes and summarizes delayed chemotherapy-induced nausea and vomiting in pediatric cancer patients, covering overview, influencing factors, assessment tools, and non-pharmacological interventions, aiming to provide insights for clinical prevention and intervention strategies targeting delayed chemotherapy-induced nausea and vomiting in pediatric patients.

Diabetes is a chronic disease that requires lifelong medication and long-term management. The longer the duration of the disease, the more likely it is to lead to progressive chronic complications affecting the eyes, kidneys, nervous system, and cardiovascular system. These complications may result in gradual functional decline or even organ failure, and may also trigger severe acute metabolic disorders. The cumulative financial burden on patients and their families can be substantial, giving rise to what is known as financial toxicity, which in turn may negatively affect patients' health outcomes. This review comprehensively explores the concept of financial toxicity in diabetic patients, including its assessment tools, influencing factors, and coping strategies. It also offers targeted suggestions aimed at informing the development of more scientific and effective systemic interventions, with the ultimate goal of improving treatment outcomes and quality of life for individuals living with diabetes.

The aim of this study is to identify the cause of death of a South China tiger cub at the Meihuashan breeding institute of Fujian Province.Pathogenic bacteria were isolated and cultured from liver,spleen,lung and other tissue samples of the dead South China tiger aseptically.The iso-lated bacteria were identified through morphological observation,biochemical characterization,sequence analysis of housekeeping gene gyrB,virulence gene detection,animal pathogenicity test and drug sensitivity test.A pathogenic Aeromonas hydrophila strain,designated FJ/Tiger-201809 was successfully isolated from the trachea of dead South China tiger.The nucleotide sequence ho-mology between the isolate and 11 strains of Aeromonas gyrB ranged from 91.2％to 99.1％,with the highest homology of 99.1％observed with Aeromonas hydrophila(AF208251.1).Genetic evo-lution analysis showed that the isolated strain FJ/Tiger-201809 was in the same evolutionary branch as other reference strains of Aeromonas hydrophila and was closely related.The pathoge-nicity test in mice showed artificial infection of mice with the strain resulted in varying degrees of lesions in several organs of the mice,and the median lethal dose(LD50)was 1 × 107.8 CFU/mL.Virulence gene test results showed that the isolate FJ/Tiger-201809 carried two virulence genes,aer and act.The results of drug sensitivity test showed that FJ/Tiger-201809 was highly sensitive to enrofloxacin and ampicillin among 18 commonly used antibiotics,relatively sensitive to penicil-lin G and doxycycline,and resistant to the other 14 antibiotics.In conclusion,this study isolated and identified a strain of Aeromonas hydrophila from a dead South China tiger with multiple drug resistance and strong pathogenicity,which provided an important reference for the prevention and control of bacterial diseases in South China tiger.

Robotic surgery, as an increasingly widespread application in the treatment of gastric and colorectal cancer, still faces obvious discrepancies in recommendations, indications, and evidence strength across existing guidelines. This study systematically analyzed 31 relevant guidelines and consensus statements (retrieved from Chinese and English databases from January 2010 to May 2025) from two dimensions: feasibility (effectiveness, safety, etc.) and training quality control.The results showed that colorectal cancer guidelines had a higher proportion (4 guidelines) of "clear recommendations" for robotic surgery, while gastric cancer guidelines predominantly presented "conditional recommendations" or no recommendations. In the training and quality control dimension, although structured suggestions received positive recommendations, more than half were based on low or very low-quality evidence. Evidence mapping indicated insufficient matching between "case-specific recommendations" and evidence grades in the feasibility dimension, while training processes emphasized the importance of standardized systems and team collaboration.The study highlights the existing heterogeneity in evidence-based guidelines for robotic gastrointestinal surgery, with colorectal cancer demonstrating a more mature evidence base and gastric cancer showing notable evidence gaps. It is recommended that future guideline development should strengthen the consistency between recommendation grades and evidence levels, promote high-quality research in upper gastrointestinal surgery, and improve surgeon training and certification systems to facilitate standardized clinical translation of robotic gastrointestinal surgery.
