Objective: To investigate the efficacy and safety of intelligent temperature-pressure-controlled flexible ureteroscopy combined with negative-pressure suction sheath lithotripsy in the treatment of upper urinary tract stones ≤2.5 cm. Methods: The clinical data of 225 patients with ≤2.5 cm upper urinary tract stones treated with this surgical method in our department during Aug. 2023 and Jul. 2024 were retrospectively analyzed. The patients were divided into the dual-control group (n=36) and conventional group (n=189) according to whether or not the intelligent temperature and pressure control device was used during operation. In the dual-control group，the intraoperative temperature and pressure in the renal pelvis were monitored and controlled in real time by the temperature and pressure sensors distributed at the end of the ureteral soft lens. The perioperative parameters，stone-removal rate，complication rate and renal function were compared between the two groups. Results: All operations were successfully completed in both groups. The postoperative procalcitonin (PCT) level [(22.75±5.85) ng/L vs. (29.08±6.60) ng/L，P=0.001]，difference in the white blood cell (WBC) level [(0.24±2.12)×10 cells/L vs. (1.19±2.17)×10 cells/L，P=0.016]，incidence of fever (2.8% vs. 16.9%，P=0.028) and overall complication rate (5.6% vs. 19.6%，P=0.042) were significantly lower in the dual-control group than in the conventional group，while the stone-clearance rate was slightly higher (88.9% vs. 82.5%，P=0.346)，with no significant difference. Conclusion: For upper urinary tract stones ≤2.5 cm，intelligent temperature-pressure-controlled ureteroscopy combined with negative-pressure suction sheath lithotripsy has a satisfactory stone-removal rate and a low rate of complications，which is worthy of clinical promotion.

Objective To observe the effects of electroacupuncture on intestinal flora and serum inflammatory factors in rabbit model with rheumatoid arthritis(RA);To explore the mechanism of its therapeutic effect on RA.Methods RA model rabbits were established by ovalbumin induction combined with Freund's complete adjuvant,and the rabbits after successful modeling were randomly divided into model group,probiotic group and electroacupuncture group,with 6 rabbits in each group.Another 6 rabbits were set as the normal group.The electroacupuncture group received electroacupuncture at the bilateral"Zusanli"and"Dubi"for 30 minutes,the probiotic group was given probiotic capsules solution(14.5 mg/kg)by gavage,once a day,for two consecutive weeks.The knee joint circumference and pain threshold of rabbits were measured,histopathological morphological changes of colonic tissue and synovial tissue ws observed by HE staining,16S rDNA sequencing was used to analyze structural changes of intestinal flora,the contents of TNF-α,IL-1β and IL-6 in serum were detected by ELISA.Results Compared with the normal group,the circumference of knee joint of rabbits in the model group increased significantly,the pain threshold was significantly decreased(P<0.01);the colonic mucosal damage was serious,the goblet cells were missing,a large number of inflammatory cells were infiltrate;the joint capsule synovial surface was rough,the synovial cell layer was hyperplasia and thickening,the synovial tissue inflammatory cell infiltration was obvious;the number and evenness of gut microbiota species decreased,while the relative abundance of Proteobacteria,Firmicutes,and Bacteroidetes decreased(P<0.05,P<0.01),the relative abundance of Desulfobacteria increased(P<0.01),while the relative abundance of Campylobacter,Lawsonella,and Pseudomonas increased(P<0.01),while the relative abundance of Heshanomonas and Herbaspirillum decreased(P<0.01);the contents of serum TNF-α,IL-1β and IL-6 increased(P<0.01).Compared with the model group,the knee joint circumference of the probiotic group and the electroacupuncture group decreased,the pain threshold increased(P<0.01,P<0.05);the degree of intestinal mucosal damage was reduced,the goblet cells were basically arranged neatly,the inflammatory cell infiltration was reduced;synovial cells proliferation and thickening decreased,with a small amount of inflammatory cell infiltration;the number and evenness of gut microbiota species increased,while the relative abundance of Proteobacteria,Firmicutes,and Bacteroidetes increased(P<0.05,P<0.01),the relative abundance of Desulfobacteria decreased(P<0.01),while the relative abundance of Campylobacter,Lawsonella and Pseudomonas decreased(P<0.01),the relative abundance of Heshanomonas and Herbaspirillum increased(P<0.05,P<0.01);the contents of serum TNF-α,IL-1β and IL-6 significantly decreased(P<0.01).Conclusion Electroacupuncture can significantly improve the symptoms of RA rabbits and reduce the inflammatory reaction in synovial tissue of joint,and the mechanism may be related to the regulation of intestinal flora structure.

This study used the Appraisal of Guidelines Research & Evaluation-Health Systems （AGREE-HS） to demonstratively compare 34 global coronavirus disease-2019 （COVID-19） health systems guidance documents （HSGs） and 6 World Health Organization （WHO） standard HSGs. The comparison involved topic， participants， methods， recommendations， and implementability， with the aim of exploring the characteristics of emergency HSGs. The results showed that the emergency HSGs had an overall average score of 49%， with topic having the highest score， recommendations having the second highest score， and participants having the lowest score. The standard HSGs had an overall average score of 79%， with high scores in all items. The emergency HSGs had lower scores in participants， methods， recommendations， and implementability than the standard HSGs （P<0.001）， while the COVID-19 emergency HSGs developed by the WHO had higher score in topic than the standard HSGs （P<0.05）. Compared with those released by countries， the COVID-19 emergency HSG developed by the WHO showed superiority in all items and overall scores （P=0.000 2）. This indicates that emergency HSGs， represented by the COVID-19 emergency HSG， place equal emphasis on topic and recommendations as standard HSGs but have low requirements in terms of expert participation， evidence support， and comprehensive consideration in the time- and resource-limited context. They have the characteristics of prominent topics， clear purposes， orientation to demand， keeping up with the latest evidence， flexible adjustment， and timeliness， emphasizing immediate implementation effects， weakening long-term effects， and focusing on comprehensive benefits. Additionally， developers， types， and report completeness are important influencing factors.

The scientific rigor and efficacy of methodologies employed in drafting emergency health systems guidance documents （HSGs） are paramount in guaranteeing the quality， reliability， and applicability of HSGs. According to the Appraisal of Guidelines for Research and Evaluation- Health Systems （AGREE-HS）， we demonstratively assessed both global coronavirus disease-2019 （COVID-19） emergency HSGs and World Health Organization （WHO） standard HSGs to uncover the core attributes of methods employed in the development of emergency HSGs. Our evaluation findings revealed that across the five assessment items of AGREE-HS， methods in the 34 emergency HSGs evaluated ranked third， trailing behind topic and recommendations. Notably， criterion 2 （the best available and most contextually relevant evidence is considered） received the highest score， whereas criterion 5 （evidence of cost and cost-effectiveness of the potential options is described） scored the lowest. Compared with the WHO standard HSGs， the COVID-19 emergency HSGs exhibited low scores in methods （P<0.05）， which was reflected in nine criteria （P<0.05）， especially in criteria 1 （systematic and transparent methods are used to identify and review the evidence） and 9 （systematic and transparent methods are used to agree upon the final recommendations）. Among the COVID-19 emergency HSGs， that developed by the WHO achieved higher scores in eight out of all nine criteria， excluding criterion 8 （P<0.05）. The clinically relevant emergency HSGs had higher scores in the criteria 3 （the evidence base is current） and 8 （the rationale behind the recommendations is clear） than other types of emergency HSGs. Collectively， the methodology for developing emergency HSGs， represented by the COVID-19 emergency HSG， underscores evidence orientation and integrates expert consensus. It is characterized by adaptable evidence synthesis strategies， streamlined evidence review protocols， and contextual relevance， all of which are influenced by external， internal， and implementation-specific factors.

Objective To assess the value of cardiac magnetic resonance(CMR)imaging for predicting adverse left ventricular remodeling in patients with ST-segment elevation myocardial infarction(STEMI).Methods We retrospectively analyzed the clinical data and serial CMR(cine and LGE sequences)images of 86 STEMI patients within 1 week and 5 months after percutaneous coronary intervention(PCI),including 25 patients with adverse LV remodeling and 61 without adverse LV remodeling,defined as an increase of left ventricular end-systolic volume(LVESV)over 15%at the second CMR compared to the initial CMR.The CMR images were analyzed for LV volume,infarct characteristics,and global and infarct zone myocardial function.The independent predictors of adverse LV remodeling following STEMI were analyzed using univariate and multivariate Logistic regression methods.Results The initial CMR showed no significant differences in LV volume or LV ejection fraction(LVEF)between the two groups,but the infarct mass and microvascular obstructive(MVO)mass were significantly greater in adverse LV remodeling group(P<0.05).Myocardial injury and cardiac function of the patients recovered over time in both groups.At the second CMR,the patients with adverse LV remodeling showed a significantly lower LVEF,a larger left ventricular end-systolic volume index(LVESVI)and a greater extent of infarct mass(P<0.001)with lower global peak strains and strain rates in the radial,circumferential,and longitudinal directions(P<0.05),infarct zone peak strains in the 3 directions,and infarct zone peak radial and circumferential strain rates(P<0.05).The independent predictors for adverse LV remodeling following STEMI included the extent of infarct mass(AUC=0.793,95%CI:0.693-0.873;cut-off value:30.67%),radial diastolic peak strain rate(AUC=0.645,95%CI:0.534-0.745;cut-off value:0.58%),and RAAS inhibitor(AUC= 0.699,95%CI:0.590-0.793).Conclusion The extent of infarct mass,peak radial diastolic strain rate,and RAAS inhibitor are independent predictors of adverse LV remodeling following STEMI.

Abstract Gurrently, healthy behaviors are the cornerstone of both physical and mental wellbeing,and more researches are focusing on improving behaviors to alleviate depression among children and adolescents. Based on the concept of 24 h movement behaviors proposed in recent years, the study examines the relationship among physical activity, sedentary behavior, sleep and depressive symptoms in children and adolescents. The research suggests that physical activity could effectively alleviate depression among children and adolescents, and its effectiveness is influenced by factors including type, intensity, duration and frequency of physical activity. Excessive sedentary behavior may increase depressive symptoms, and the impacts of different types, durations, and frequencies of sedentary behavior on depressive symptoms among children and adolescents vary. In addition to its direct impact on depression, sleep could also serve as a mediator among physical activity, sedentary behavior and depression, and there is also a crowdingout effect of time between physical activity and sedentary behavior. Future research should focus on the mechanisms and pathways underlying how 24 h movement behaviors affecting depression among children and adolescents, in order to provide more accurate solutions for the prevention and treatment of depression.

Objective To investigate the changes of serum cardiac-specific troponin I (cTnI) level in patients after lung transplantation. Methods Clinical data of patients undergoing lung transplantation in our hospital from December 2016 to December 2022 were retrospectively analyzed. The relationship between postoperative serum cTnI level and clinical characteristics were explored. Results Finally 20 patients were collected, including 15 males and 5 females with an average age of (51.65±12.79) years. The serum cTnI level was significantly increased after lung transplantation. The serum cTnI reached the highest level on the first day after transplantation, and significantly decreased from the third day after transplantation. The serum cTnI levels in patients with obstructive pulmonary disease and bilateral lung transplantation were significantly higher than those in patients with restrictive pulmonary disease and unilateral lung transplantation on the day after surgery and on the first day after transplantation. Conclusion Transient myocardial injury can occur after lung transplantation, which is characterized by an abnormal increase in serum cTnI level.

Objective:To explore risk factors for refracture after percutaneous kyphoplasty(PKP)in elderly patients with osteoporotic vertebral compression fractures(OVCF)and provide clinical guidance.Methods:A retrospective analysis was conducted on clinical data from elderly patients with OVCF who underwent PKP surgery at the Department of Orthopedics, Shanxi Bethune Hospital, between January 2017 and December 2022.All patients were followed up for a minimum of one-year post-surgery.The elderly patients were categorized into a refracture group(59 cases)and a non-refracture group(200 cases)based on post-surgery refracture occurrence.Univariate analysis was initially conducted on the collected data, followed by multivariate Logistic regression analysis on statistically significant indicators to identify risk factors for refracture in elderly patients with OVCF following PKP.Results:The results of the univariate analysis indicated that there was no statistically significant difference in gender, history of diabetes mellitus, history of smoking, history of hormone medication, and body mass index(BMI)between the refracture group and the non-refracture group of elderly patients.However, the refracture group was found to be older than the non-refracture group( t=9.085, P=0.003).Additionally, there were no significant differences in preoperative indicators such as preoperative calcium, preoperative phosphorus, and site of first fracture(all P>0.05).The time from first fracture to surgery being greater than 14 days was more common in the refracture group compared to the non-refracture group( χ2=20.409, P=0.001), and the number of vertebrae fractured for the first time was higher in the re-fracture group( t=6.189, P=0.017).Cement injection method, amount of cement injected, and distribution of cement did not show significant differences between the two groups(all P>0.05).However, there were statistically significant variations in the proportion of postoperative anti-osteoporosis treatment( χ2=13.431, P=0.001)and bone mineral density( χ2=13.431, P=0.001)between the refracture and non-refracture groups.Furthermore, multifactorial Logistic regression analysis revealed that increasing age( OR=1.061, 95% CI: 1.021-1.103, P=0.003), time from first fracture to surgery exceeding 14 days( OR=5.026, 95% CI: 1.968-12.835, P=0.001), lack of anti-osteoporosis treatment( OR=3.493, 95% CI: 1.239-9.846, P=0.018), and decreased bone mineral density( OR=10.682, 95% CI: 2.707-42.151, P=0.001)were identified as influential factors in the occurrence of secondary vertebral compression fracture after surgery. Conclusions:The independent risk factors for refracture after PKP in elderly patients with OVCF include increasing age, time from first fracture to surgery greater than 14 days, lack of anti-osteoporosis treatment, and decreased bone mineral density.In clinical practice, targeted interventions can be implemented for prevention and effective management based on these risk factors to enhance the prognosis of elderly patients with OVCF.

Objective:To investigate the clinical features of chronic spontaneous urticaria (CSU) patients with angioedema (AE) .Methods:Clinical data were collected from adult outpatients with active CSU diagnosed and treated at the First Hospital of China Medical University from January 2019 to December 2021, and analyzed retrospectively. The data included gender, age, disease duration, the presence or absence of angioedema, urticaria activity score for one day, prior treatments, previous history, family history, laboratory test results, therapeutic effect, and adverse reactions. Their treatment regimens were based on the Chinese guidelines for the diagnosis and treatment of urticaria (2018) and the American guidelines for the diagnosis and management of urticaria (2014). Statistical analysis was carried out by using Mann-Whitney U test, two-independent-sample t test, Chi-square test, corrected Chi-square test, and Fisher's exact test. Results:A total of 131 CSU patients were collected, including 78 females and 53 males. Their age at the first visit was 44.6 ± 13.3 years, and the disease duration ( M[ Q1, Q3]) was 4.0 (2.0, 10.0) months. Among these CSU patients, there were 58 with AE and 73 without AE. The disease duration was significantly longer in the CSU patients with AE (6.0 [3.0, 24.0] months) than in those without AE (3.5 [2.0, 6.0] months; Z = -2.78, P = 0.005). The urticaria activity score for one day was also significantly higher in the CSU patients with AE (5.0 [3.0, 5.3] points) than in those without AE (4.0 [3.0, 5.0] points; Z = -2.63, P = 0.008). The CSU patients with AE showed a decreased proportion of patients completely controlled by licensed-dose second-generation H1-antihistamines (sgAHs) (8.6%, 5/58) compared with those without AE (24.7%, 18/73), but an increased proportion of patients uncontrolled by licensed-dose sgAHs (91.4%, 53/58) compared with those without AE (74.0%, 54/73; Z = -2.53, P = 0.011) ; there were no significant differences in the proportions of patients completely controlled or uncontrolled by updosed sgAHs alone or combinations of 2- to 4-fold equivalent-dose sgAHs, or in the proportions of patients completely controlled or uncontrolled by combination therapy with 4-fold equivalent-dose sgAHs and non-H1-antihistamines between the CSU patients with AE and those without AE ( P > 0.05) . Conclusion:Compared with the CSU patients without AE, the CSU patients with AE had a longer disease duration, higher disease activity, a lower proportion of patients completely controlled by licensed-dose sgAHs, and a higher proportion of patients uncontrolled by licensed-dose sgAHs.
