The report Cancer Statistics, 2026 systematically estimated new cancer cases and deaths in the United States for 2026 and provided an overview of long-term cancer trends in the country. This article focuses on the core data for children and adolescents (aged 0–19 years) from the report, interpreting the incidence, survival, and mortality rates, their temporal trends, and the long-term risks among survivors. By comparing these findings with the latest childhood and adolescent cancer burden data in China, we propose implications for cancer prevention and control in Chinese children and adolescents.

Objective To explore the psychological experiences of operating room nurses participating in organ transplant surgeries, providing a basis for medical institutions to develop targeted psychological support programs. Methods Using a phenomenological research method, semi-structured, in-depth, face-to-face interviews were conducted from January to March 2026 with 17 operating room nurses who had participated in organ transplant surgeries at a tertiary hospital in Shanghai. Interviews were recorded, and observations were made. The interview data were analyzed, summarized, and themes were refined using Colaizzi’s seven-step analysis method. Results The psychological experiences of operating room nurses participating in organ transplant surgeries were identified as 5 main themes and 14 sub-themes: emotional impact and empathy load (shock and grief confronting life and death, deep empathy for patients and families, awe and gratitude towards organ donors); pressure experience and physical-mental exhaustion (urgency under time pressure, load of operational precision requirements, excessive consumption of physical and mental resources); cognitive appraisal and meaning construction (reappraisal of professional value, deep reflection on the meaning of life, positioning and identification of one’s role); coping strategies and adjustment process (active learning and experiential reflection, self-emotional regulation and social support); growth experience and psychological transformation (enhancement of psychological resilience, establishment of professional confidence, deepening of professional mission). Conclusions Operating room nurses undergo complex and profound psychological experiences while participating in organ transplant surgeries, enduring strong emotional impact and physical-mental stress while also achieving psychological growth and deepening professional identity through practice. Nursing managers should pay attention to the mental health of this group and construct a multi-level support system to promote their physical and psychological well-being.

Objective To systematically review the efficacy and safety of azithromycin versus amoxicillin and clavulanate potassium in the treatment of otitis media in children.Methods PubMed,Embase,Cochrane Library,CNKI,WanFang Data and VIP databases were electronically searched to collect randomized controlled trials(RCTs)of azithromycin versus amoxicillin and clavulanate potassium in the treatment of otitis media in children from inception to February 28,2025.Two researchers independently screened the literature,extracted data,and assessed the risk of bias of the included studies.Meta-analysis was then performed using RevMan 5.3 software.Results A total of 21 RCTs involving 6,092 patients were included.The results of Meta-analysis showed that there was no statistically significant difference in the total effective rate after completion of treatment[RR=0.99,95％CI(0.96,1.03),P=0.72]and the total effective rate during follow-up period[RR=0.99,95％CI(0.94,1.04),P=0.10]between amoxicillin and clavulanate potassium group and azithromycin group.The results of subgroup analysis showed there was no statistically significant difference in the total effective rate between amoxicillin and clavulanate potassium group and azithromycin group in children under two years old or 2 years old and above(P＞0.05).The incidence of diarrhea[RR=0.41,95％CI(0.28,0.60),P＜0.001],vomiting[RR=0.49,95％CI(0.28,0.87),P=0.02],nausea[RR=0.46,95％CI(0.27,0.78),P=0.004],loose stools[RR=0.44,95％CI(0.24,0.79),P=0.006],rash[RR=0.62,95％CI(0.39,0.96),P=0.03],fungal dermatitis[RR=0.32,95％CI(0.18,0.57),P＜0.001],dermatitis[RR=0.31,95％CI(0.14,0.67),P=0.003]in the azithromycin group were all lower than those in the amoxicillin and clavulanate potassium group,and the difference was statistically significant.Conclusion The current evidence shows that azithromycin versus amoxicillin and clavulanate potassium are equally effective in treating otitis media in children,but azithromycin is considered safer.Due to the limited quality and quantity of included studies,more high-quality studies are required to verify the above conclusions.

The scientific research and innovation capabilities of medical students are intrinsically linked to the sustained and high-quality development of national healthcare initiatives.Cultivating outstanding medi-cal students with independent scientific capabilities and innovative consciousness is a critical component in the education and training of high-level medical professionals.Our investigation revealed that within the imperfections of the cultivating model,some faculty and students at medical schools have an insufficient understanding of scientific research and innovation and lack motivation for engaging in such activities,which hinder the progression of scientific research activities.Consequently,we initiated a teaching practice and exploratory study on the"tutorial system"aimed at fostering medical students'scientific research and innovation abilities.Based on the principle of"research informing teaching,teaching and research advan-cing together,"this study implements a"tutorial system"coordinated by tutors,supplemented by graduate and undergraduate student mentors,to cultivate innovative thinking,stimulate interest in scientific re-search,and enhance practical and research skills among medical students.Through collaborative efforts within"scientific research innovation teams,"various educational methods—including preliminary re-search,in-class and extracurricular activities,intra-group and inter-group interactions,and theoretical and practical applications—are employed to improve and strengthen the cultivation of medical students'scientif-ic research and innovation abilities.This study aims to provide valuable references for optimizing medical education management systems and enhancing the quality of medical student training.

Aim To predict and verify the potential mechanism of the compatibility of"ginseng-astragalus-pueraria"in protecting islet morphology and improving insulin resistance by using network pharmacology.Methods The active ingredients and targets of the horn medicine were obtained from three platforms:TC-MSP,TCMIP,and BATMAN.The targets of type 2 dia-betes mellitus(T2DM)were obtained from three plat-forms:TTD,OMIM,and disgeNET.The PPI network was constructed by using the STRING database and Cy-toscape 3.9.1;GO and KEGG analysis were per-formed;POCASA 1.1 was used to predict protein binding sites,and AutoDock Vina1.1.2 was used for docking and experimental verification.Results"Gin-seng-astragalus-pueraria"screened out 2 021 targets,of which 152 were closely related to T2DM,and 10 key genes and the AGE-RAGE signaling pathway were i-dentified.Molecular docking showed that quercetin had good binding to RAGE,INS,and PI3K.Experi-ments showed that the horn drug increased insulin binding rate and secretion index and reduced serum in-sulin level and insulin resistance index.These data benefited from"ginseng-astragalus-pueraria"reducing the expression of AGE-RAGE,activating PI3K-Akt,in-hibiting NF-κB,and reducing the expression of IL-6,IL-1β and TNF-α.Conclusion The study suggests that"ginseng-astragalus-pueraria"regulates the AGE-RAGE/PI3K-Akt/NF-κB signaling pathway,repairs damaged islet morphology,and improves insulin resist-ance.

Objective:To investigate the efficacy of combined sufentanil and remifentanil in pediatric ear, nose, and throat surgeries.Methods:This study used a prospective study design. A total of 110 pediatric children who underwent elective ear, nose, and throat surgery at Xi'an Children's Hospital from January 2022 to December 2023 were included in this study. The patients were randomly divided into a control group ( n = 55) and an observation group ( n = 55) using a random number table method. In the control group, only sufentanil was used for general anesthesia, while the observation group received both sufentanil and remifentanil during the anesthesia process. The changes in average arterial pressure and heart rate were compared between the two groups at five time points: T1 (before anesthesia induction), T2 (during tracheal intubation), T3 (at the start of surgery), T4 (5 min after the start of surgery), and T5 (immediately after surgery). Additionally, the recovery time for spontaneous breathing, the time to open eyes, extubation time, and adverse reactions were compared between the two groups. Ramsay sedation scores were compared between the two groups at three time points: T6 (5 min after extubation), T7 (15 min after extubation), and T8 (30 min after extubation). Pain Visual Analog Score was compared between the two groups at T8 (30 min after extubation), T9 (60 min after extubation), and T10 (90 min after extubation). Results:The differences in average arterial pressure and heart rate between the two groups at time points T1-T5, as well as Ramsay sedation scores at T6-T8 and Visual Analog Score scores at T8-T10, were all statistically significant ( F = 152.93, 2 718.29, 2 347.47, 751.77, all P < 0.05). In the observation group, the recovery time for spontaneous breathing [(5.37 ± 2.18) min vs. (6.74 ± 2.42) min], the time to open eyes [(9.03 ± 2.02) min vs. (10.84 ± 3.11) min], and extubation time [(13.22 ± 4.22) min vs. (16.47 ± 5.14) min] were significantly shorter in the observation group than in the control group ( t = 3.11, 3.62, 3.62, all P < 0.001). The incidence of adverse reactions was significantly lower in the observation group than in the control group [3.64% (2/55) vs. 16.36% (9/55), χ2 = 4.94, P < 0.05]. Conclusions:Both sufentanil alone and in combination with remifentanil yield effective anesthesia outcomes in pediatric ear, nose, and throat surgeries. However, the combination of sufentanil and remifentanil significantly shortens the recovery time for spontaneous breathing, the time to open eyes, and extubation time. This combined approach also lowers the incidence of adverse reactions, improves surgical outcomes, and promotes postoperative recovery of children.

Objective:To evaluate the clinical efficacy of proximal femoral reconstruction osteotomy (PFRO) in hip revision arthroplasty.Methods:A retrospective analysis was conducted of the 92 patients (93 hips) who had undergone PFRO in hip revision arthroplasty at Department of Orthopedics, The First Affiliated Hospital, University of Science and Technology of China from January 2019 to December 2023. The cohort included 50 males (51 hips) and 42 females (42 hips), with an age of (64.5±11.7) years and a body mass index of (23.7±2.9) kg/m 2. Surgical procedures were performed under general anesthesia via a posterolateral approach. Biologic prostheses were used in femoral reconstruction, and PFRO fragments repositioned and fixed using cerclage wires. The data collected were operative time, intraoperative blood loss, length of osteotomy fragments, healing at the osteotomy site, intraoperative and follow-up complications, as well as Harris hip score (HHS) and leg length discrepancy (LLD) at the last follow-up. Results:For this cohort, operative time was (174.9±45.6) minutes, intraoperative blood loss (594.6±206.6) mL, and length of osteotomy fragments (12.3±2.3) mm. The 92 patients were followed up for (35.8±12.3) months. For them, HHS improved from preoperative (38.3±8.5) points to (80.5±12.8) points at the last follow-up, and LLD decreased from preoperative (21.2±13.0) mm to 2.0(0.0, 5.0) mm at the last follow-up, showing significant differences ( P<0.05). The osteotomy sites healed in 89 cases (90 hips), with a displacement of the greater trochanter <5 mm; 3 cases (3 hips) experienced nonunion with wire loosening and a displacement of the greater trochanter >10 mm. The osteotomy fragment of the greater trochanter got fractured in 2 patients (2 hips) and a fracture of the medial cortex of the proximal femur occurred in 11 patients (11 hips), but follow-ups observed healing of all the fractures. One patient (1 hip) developed postoperative posterior dislocation of the hip which was treated conservatively. One patient (1 hip) developed postoperative periprosthetic infection which did not recur after twice of debridement followed by prosthetic revision of the proximal femoral tumor. Conclusion:In hip revision arthroplasty, as PFRO demonstrates a low incidence of fragment fractures of the greater trochanter and a high rate of healing at the osteotomy site, its short-term clinical outcomes are satisfactory.

Objective:To investigate the therapeutic effects of the copper chelator ammonium tetrathiomolybdate (TTM) on rheumatoid arthritis (RA) in a mouse model.Methods:Twenty-four male dilution brown non-Agoutia/1 mice were randomly divided into 4 groups: a blank control group (Ctrl group, n=6), a collagen-induced arthritis (CIA) + phosphate buffer saline (PBS) treatment group (PBS group, n=6), a CIA+TTM treatment group (TTM group, n=6), and a CIA+Elesclomol treatment group (Eles group, n=6). Eles, a copper ion carrier, served as a control for administration of TTM, a copper ion chelator. One week after treatment, the swelling of mouse paw was observed, and the clinical scoring of the arthritis in mice was evaluated once a week. Paw mechanical pain detection was performed and photographs were taken to observe the severity of paw swelling before the mice were sacrificed. Catwalk gait analysis system was used to evaluate the gait changes in mice. HE and saffron O solid green staining were used to evaluate pathomorphologic changes in the mice knee joints and paws. Immunostaining techniques were used to detect the protein expression of MMP3, CD31, and VEGF in the mice paws. Luminex technology was used to detect alterations in the serum inflammatory factors. Results:Compared with the Ctrl group, in the PBS and Eles groups, the joints were red, swollen and deformed; the arthritis clinical scores were significantly higher; the bone destruction, synovial hyperplasia and inflammatory cell infiltration and pathological changes in the joint tissues were obvious; the expression levels of inflammatory factors, such as serum MCP-1, IL-1 β, IL-9, and IFN- γ, were significantly higher while the expression level of IL-10 was significantly lower. Simultaneously, the expression of CD31 and VEGF factors was significantly enhanced. Compared with the PBS group, in the TTM group, the joint swelling and deformation were significantly improved, the arthritis clinical score was reduced, and the joint bone destruction, inflammatory cell infiltration and synovial hyperplasia were alleviated, and the levels of serum MCP-1, IL-1 β, IL-9 and IFN- γ were significantly decreased while the level of anti-inflammatory factor IL-10 was increased. There was no significant difference in the expression of MMP-3, CD31 or VEGF factors between the CTRL group and the TTM group. Conclusion:TTM can block synovial inflammation, angiogenesis, and bone destruction multiple times by simultaneously targeting multiple inflammatory factors, VEGF factors, and bone destruction mediators, thereby alleviating the pathological damage to the joint tissues induced by CIA in RA mice.
