Objective:To investigate the real experience of early postoperative kinesiophobia in school-aged children after limb frac-ture surgery.Methods:A descriptive qualitative research method was used to conduct semi-structured interviews with sixteen children with limb fractures and their families in the ward of pediatric orthopedics in a grade A tertiary hospital in Chongqing,China,and a con-tent analysis was used to summarize and extract key themes from the interview data.Results:Three main themes and ten subthemes were extracted.The theme of pain cognition and catastrophic thinking included the subthemes of children's pain perception and activ-ity restriction,parents'pain perception and catastrophic reactions,and the interactive influence of pain cognition among different indi-viduals;the theme of medical education and risk perception included the subthemes of fear and concerns about refracture,the relation-ship between personality traits,help-seeking behavior,and internal-ized anxiety,and the impact of medical education on risk percep-tion;the theme of psychosocial stress and self-motivation included the subthemes of family members'attitudes toward academic inter-ruption,children's social disruption and compensatory media use,the mutual influence of compensatory indulgence and reinforced sick role behavior,and positive reinforcement enhancing children's self-driven recovery.Conclusion:Healthcare providers should closely monitor the recovery of limb motor function in the early stage af-ter surgery in children with fractures and provide personalized medical services and rehabilitation guidance to children and their fami-lies based on the pain perception,personality traits,and rehabilitation needs of children.

Sarin(GB)is a typical representative of nerve agents with high toxicity,and very low amount can cause death.GB can cause water and atmospheric environment poisoning,so the detection of GB in water and air is of great significance.In this work,a colorimetric sensor array(CSA)based on GB inhibition of cholinesterase activity was constructed to detect GB with high selectivity.A 4×4 colorimetric array was constructed using acetylcholinesterase(AChE),butyryl cholinesterase(BuChE)and the corresponding substrate acetylthiocholine iodide(S-ACh),butyryl thiocholine iodide(S-BCh),acetylcholine chloride(ACh),butyryl choline chloride(BCh)and 2,6-dichloroindophenol ethyl ester(DCIE).The linear curve of the sensor was Y=131.3×lgC+271.6(R2=0.997),where Y was the array response Euclidean distance,C was the concentration of GB(mg/L),the linear range was 0.03?0.32 mg/L,and the detection limit was 27.6 μg/L.The method could effectively distinguish chemical warfare agents(CWA)such as VX,Soman(GD),mustard gas(HD),Louie reagent(L),and had high anti-interference ability,sensitivity and good repeatability.It was successfully applied to the detection of GB in simulated water and simulated air samples,and the sample recovery rate was 97.2% ?100.9%.This method would be potentially applied to the field rapid detection of nerve agents.

Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

OBJECTIVE: To investigate the clinical characteristics, treatment and prognosis of adult AML patients with NUP98::HOXA9 fusion gene. METHODS: From May 2017 to October 2023， among 2 113 AML patients who visited the Hematology Department of our hospital, patients with NUP98 rearrangements were screened. The clinical characteristics, chromosome karyotypes, immunophenotypes, gene mutations, treatment efficacy and prognosis of the patients with NUP98::HOXA9 positive were analyzed. RESULTS: Among the 2 113 AML patients, there were 18 cases with NUP98 rearrangement, including 14 NUP98::HOXA9 positive cases, with a detection rate of 0.66% (14/2 113). The median age of the NUP98::HOXA9 positive patients was 42.5 (23-64) years old. The most common chromosome karyotype was t(7; 11)(p15; p15). The immunophenotypes of all patients expressed CD13, CD33, CD117 and CD38, and most patients expressed CD34 and cMPO, while only a few expressed HLA-DR. Second-generation sequencing (NGS) was performed to detect genetic mutations associated with leukemia in all 14 patients, and the genes exhibiting a high frequency of mutation were WT1 (10/14), TET2 (7/14), and FLT3-ITD (6/14). Additionally, mutations were also observed in KRAS/NRAS, IDH1, and KIT. Of the 13 patients who received treatment, 9 achieved complete remission (CR), and all 3 patients who received azacytidine(AZA)+ venetoclax (VEN) regimen achieved CR after the first course of treatment. Within this cohort, 6 patients were classified as relapsed/refractory (6/13). 4 patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), of which two achieved long-term survival. The median follow-up time was 12 (2.1-65.0) months, while the median overall survival (OS) and relapse-free survival (RFS) were recorded as 11.4 months and 9.6 months, respectively. CONCLUSION The most common type of NUP98 rearrangement in adults AML patients is NUP98::HOXA9 , which is often accompanied by somatic mutations in WT1, TET2, and FLT3-ITD. These patients are prone to relapse, have short survival time, and generally face poor prognoses. Hopefully, utilization of the AZA+VEN regimen is anticipated to enhance the rate of induced remission in the patients, and some patients may prolong their survival through allo-HSCT. However, more effective treatment methods are still needed to improve the overall prognosis of these patients.

OBJECTIVE: To describe survival trends and global patterns of esophageal cancer (EC) using survival data from population-based cancer registries. METHODS: We systematically searched PubMed, EMBASE, Web of Science, SEER, and SinoMed databases for articles published up to 31 December 2023. Eligible EC survival estimates were evaluated according to country or region, period, sex, age group, pathology, and disease stage. RESULTS: After 2010, Jordan exhibited the highest age-standardized 5-year relative survival rates (RSRs)/net survival rates (NSRs) at 41.1% between 2010 and 2014, while India had the lowest, at 4.1%. Survival rates generally improved with diagnostic age across most countries, with significant increases in South Korea and China, of 12.7% and 10.5% between 2000 and 2017, respectively. Survival was higher among women compared to men, ranging from 0.4%-10.9%. Survival rates for adenocarcinoma and squamous cell carcinoma were similar, differing by about 4%. In China, the highest age-standardized RSRs/NSRs was 33.4% between 2015 and 2017. Meanwhile, the lowest was 5.3%, in Qidong (Jiangsu province) between 1992-1996. CONCLUSION Global EC survival rates have improved significantly in recent decades, but substantial geographical, sex, and age disparities still exist. In Asia, squamous cell carcinoma demonstrated superior survival rates compared to adenocarcinoma, while the opposite trend was observed in Western countries. Future research should clarify the prognostic factors influencing EC survival and tailor prevention and screening strategies to the changing EC survival patterns.

Objective To evaluate the efficacy,safety,and cost-effectiveness of berberine-based quadruple therapy vs.the clarithromycin-based quadruple therapy for Helicobacter pylori(H.pylori)eradication in treatment-na?ve patients.Methods This was a single-center,prospective,open-label randomized controlled trial.A total of 404 treatment-naive patients with H.pylori infection who visited the Outpatient Department of Gastroenterology,the First Medical Center of Chinese PLA General Hospital from September 2021 to May 2024 were enrolled.The patients were randomly assigned in a 1:1 ratio to two groups:berberine quadruple therapy group(berberine+amoxicillin+esomeprazole+colloidal bismuth pectin;n=202)and clarithromycin quadruple therapy group(clarithromycin+amoxicillin+esomeprazole+colloidal bismuth pectin;n=202).Both groups received a 14-day treatment course.The H.pylori eradication rate,incidence of adverse reactions,medication compliance,and treatment costs were compared between the two groups.Results By intention-to-treat(ITT)analysis,eradication rate did not differ significantly between the two groups[89.1%(180/202)in berberine quadruple therapy group vs.89.6%(181/202)in clarithromycin quadruple therapy group,P=0.872].The per-protocol(PP)analysis also showed no significant difference in the eradication rate between the two groups[90.4%(179/198)vs.91.3%(178/195),P=0.763].The incidence of adverse reactions in berberine quadruple therapy group was significantly lower than that in clarithromycin quadruple therapy group[18.2%(36/198)vs.38.5%(75/195),P<0.001].Specifically,the incidence of taste disturbance in berberine quadruple therapy group was significantly lower than that in clarithromycin quadruple therapy group(3.0%vs.15.4%,P<0.001).There was no statistically significant difference in medication compliance between the two groups[98.5%(195/198)in berberine quadruple therapy group vs.97.9%(191/195)in clarithromycin quadruple therapy group,P=0.688].The fixed direct medical cost per patient was significantly lower in berberine quadruple therapy group than that in clarithromycin quadruple therapy group(402.08 yuan vs.693.94 yuan).Conclusions The berberine-based quadruple therapy is as effective as traditional clarithromycin-based quadruple therapy for eradicating H.pylori,with the advantages of a lower incidence of adverse reactions and lower cost.It represents a safe,effective,and economical treatment option worthy of further promotion and application.

Child safety seats have been proven to be one of the most effective tools for protecting child passengers. However, the widespread phenomenon of safety seats being "unavailable," "owned but not used," or "used incorrectly" is prevalent globally. This paper aims to summarize the obstacles to the use of child safety seats from four aspects: Individual, society, environment and policy, in order to provide a basis for follow-up comprehensive intervention to ensure the safety of children.

ObjectiveTo explore the role and molecular mechanism of Weifuchun （WFC） in inhibiting inflammation and alleviating gastric precancerous lesions （GPL）. MethodHuman gastric mucosal epithelial cells （GES-1） were stimulated with N-methyl-N′-nitro-N-nitrosoguanidine （MNNG） for the modeling of GPL （MC cells）， with Caspase-3 inhibition by Z-DEVD-FMK. MC cells were divided into control （20% blank serum）， WFC （15% and 20% WFC-containing serum）， and caspase-3 inhibitor groups. The cell counting kit-8 （CCK-8） was used to examine the viability of GES-1 cells or MC cells. The Transwell assay and 5-acetylidene-2′-deoxyuridine （EdU） staining were employed to examine cell invasion and proliferation， respectively. Flow cytometry was employed to determine the level of reactive oxygen species. Real-time PCR was conducted to determine the mRNA levels of interleukin （IL）-1， IL-6， and tumor necrosis factor （TNF）-α. Gene Expression Omnibus （GEO） was used to analyze the role of pyroptosis in gastric cancer progression. Western blotting was employed to determine the protein levels of nuclear factor-κB （NF-κB） p65， gasdermin E （GSDME）， and Caspase-3. Immunofluorescence staining was employed to detect the NF-κB p65 protein level and nuclear translocation. Hematoxylin-eosin staining was carried out to observe the pathological changes in the gastric mucosa before and after WFC treatment in the patients. ResultCompared with the control group， MC cells presented enhanced proliferation and invasion energy （P<0.01）. Compared with the blank serum group， WFC-containing serum inhibited the proliferation and invasion of MC cells （P<0.01）， down-regulated the mRNA levels of IL-1， IL-6， and TNF-α， and lowered the level of reactive oxygen species （P<0.05， P<0.01）. The transcriptome data at different stages of gastric cancer showed that pyroptosis was involved in gastric cancer progression， and the GSDME level was significantly higher in GPL patients than in the normal group. Compared with the blank serum， WFC-containing serum lowered the level of NF-κB and inhibited the nuclear translocation of NF-κB （P<0.05）， and it inhibited pyroptosis by suppressing the cleavage of Caspase-3 on GSDME （P<0.05， P<0.01）. The analysis of patient specimens further demonstrated that WFC treatment down-regulated the NF-κB level and GSDME cleavage （P<0.01）， inhibited pyroptosis， and alleviated gastric mucosal inflammation and intestinal epithelial metaplasia. ConclusionPyroptosis is involved in the progression of gastric cancer， and WFC inhibits pyroptosis via the NF-κB/GSDME pathway， thereby alleviating gastric mucosal inflammation in GPL.

Purpose Focusing on the characteristics of for-malin fixed paraffin embedded(FFPE)samples,explored nano-magnetic bead nucleic acid extraction solutions with higher qual-ity/yield and continued to improve molecular pathology technolo-gy.Methods Alternative magnetic beads were synthesised in four major categories and 15 sub-categories and we screened to obtain high-quality/yield magnetic beads centred on FFPE samples.Simulated conventional tissues,simulated coarse needle punctures(liver),and simulated fiberoptic bronchoscopy sam-ples(lungs)were sectioned with the same number of serial slices in tubes.The nucleic acids of slices were extracted using the best magnetic beads screened in this study and common com-mercially available kits,and then perform comparison and purifi-cation quality parameters such as total amount and fragment size.The downstream applications of nucleic acids were validated by PCR and Sanger sequencing.Results Screening all homemade nanomagnetic beads centered on the DNA of FFPE samples,the total recoveries of the best performance nanomagnetic beads were obtained to be 58.5％±1.58％,and the total recoveries of five commercially available commercial magnetic beads and three do-mestic kit magnetic beads ranged from 18.68％to 40.71％.The total amount of DNA(ng)extracted from the same amount of tis-sue(serial slices),the nucleic acid yield of this study in simu-lated conventional tissues,simulated coarse needle punctures,and simulated fiberoptic bronchoscopy samples were increased by 39.49％-181.72％compared with those of the commercially a-vailable kits(P＜0.05).The total amount of extracted nucleic acid from simulated fiberoptic bronchoscopy tissue sections can be more than 100 ng for 1 slice(4 μm)and more than 400 ng for 5 slices.Conclusion The DNA purification nanomagnetic beads screened with DNA from FFPE samples have a significant enhancement comparing to the existing commercial bead proto-cols,and provide space for quality assurance,automated testing,and program expansion for clinical molecular pathology testing.
