Objective: To explore the effects of a zerotime exercise (ZTEx) intervention on physical activity levels and sedentary behavior among college students, providing evidence for improving physical activity and reducing sedentary habits. Methods: In September 2023, 45 sedentary college students from a university in Fuzhou were recruited and randomly assigned to either the ZTEx group (23 students) or the control group (22 students) according to a random number table method. ZTEx group received two ZTEx focus group meetings for 3 months, while the control group received safety and health education. The International Physical Activity Questionnaire and a threeaxis accelerometer were used to evaluate the sedentary and physical activity levels of college students. At the same time, evaluations related to physical health and psychological questionnaires were completed. Mixed effects analysis of variance and nonparametric tests were used to statistically analyze the physical health, psychological questionnaire, and sedentary and physical activity data of the college students. Results: Postintervention, the ZTEx group showed significant improvements in the duration of lowintensity physical activity [pretest(1 492.78±369.50)min; posttest(1 918.93±354.63)min] and the number of sedentary interruptions [pretest(45.26±13.69)times; posttest(73.78±16.74)times]; grip strength [pretest(28.77±9.23)kg; posttest(31.78±8.00)kg]; sitting up continuously for 30 seconds [pretest(22.52±4.90)times; posttest(26.96±4.87)times]; general selfefficacy [pretest(26.52±4.14)points; posttest(32.96±5.24)points]; body composition summary [pretest(66.44±4.83)points; posttest(72.62±4.88)points]; and psychological composition summary [pretest(61.21±9.88)points; posttest(63.98±9.57)points], while reducing sedentary time [pretest(3 694.28±687.56)min; posttest(2 865.90±493.81)min] in the past 7 days, the differences were statistically significant(P<0.05). The control group exhibited no significant changes(P>0.05). Conclusion ZTEx effectively improve the lowintensity physical activity, increases sedentary breaks, and reduces prolonged sitting among college students, fostering healthier habits and improving physical/mental wellbeing.

Monkeypox is a zoonotic disease caused by the monkeypox virus, which was previously limited to epidemics in Africa. Since 2022, monkeypox has rapidly spread worldwide, affecting 130 countries and regions. The World Health Organization declared it a public health emergency of international concern, in 2022 and 2024, respectively. The monkeypox virus has exhibited accelerated mutation rates, with diverse circulating strains. Children and men who have sex with men have emerged as the primary high-risk group. Additionally, the increase in asymptomatic infections and atypical mild rashes has complicated differential diagnosis, posing entirely challenges to the diagnosis, treatment, and prevention and control of monkeypox. This article reviews the research progress on the etiological characteristics, epidemiological features, clinical manifestations, and prevention and treatment strategies of monkeypox by retrieving the literature on monkeypox from January 1958 to January 2025, so as to provide the basis for the prevention and treatment of monkeypox.

AIM:This study aims to explore the impact of Escherichia coli(E.coli)high-pathogenicity island(HPI)on pyroptosis and intestinal inflammation.METHODS:Kunming mice and IPEC-J2 cells(porcine small intesti-nal epithelial cells)were treated with HPI-containing E.coli strain(HPI+),HPI-deleting E.coli strain(ΔHPI),or lipo-polysaccharide(LPS).The intestinal lactate dehydrogenase(LDH)activity,superoxide dismutase(SOD)activity,IgA expression and secretory IgA(SIgA)content were assessed in mice.The expression of key regulatory factors in the nucleo-tide-binding oligomerization domain-like receptor protein 3(NLRP3)/caspase-1 signaling pathway-related proteins in mouse intestinal tract and IPEC-J2 cells was analyzed by RT-qPCR,immunohistochemical staining and Western blot.The levels of interleukin-1β(IL-1β)and IL-18 in mouse serum and IPEC-J2 cell culture supernatants were measured by ELISA.The pivotal role of NLRP3 in HPI+infection was confirmed by silencing NLRP3 in IPEC-J2 cells using siRNA.RE-SULTS:The HPI+infection markedly decreased SOD activity,increased IgA+B cell count,and induced the LDH release and SIgA secretion in the mouse intestine compared with ΔHPI infection.The results of ELISA,HE staining and TUNEL staining indicated that E.coli HPI triggered DNA damage,tissue injury and inflammation in mouse intestinal epithelial cells.Western blot revealed an increase in intestinal gasdermin D N-terminal fragment(GSDMD-N)protein level with HPI+infection compared with ΔHPI infection.E.coli HPI significantly up-regulated mRNA and protein expression of NLRP3,apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),caspase-1,GSDMD,IL-1β and IL-18 in mouse intestinal tissues and IPEC-J2 cells,accompanied by the elevated secretion of IL-1β and IL-18.The confo-cal microscopy demonstrated an enhanced assembly of the NLRP3 inflammasome with HPI+infection compared with ΔHPI infection,leading to colocalization of NLRP3 and caspase-1.Furthermore,NLRP3 silencing in IPEC-J2 cells attenuated E.coli HPI-induced cell inflammation,damage,and NLRP3/caspase-1 signaling pathway activation.CONCLUSION:The presence of HPI enhances the virulence of E.coli and exacerbates intestinal inflammation.Moreover,pyroptosis,regu-lated by the NLRP3/caspase-1 signaling pathway,plays a pivotal role in the intestinal injury induced by E.coli HPI.

This study aims to establish a multiplex TaqMan fluorescence quantitative PCR(qPCR)assay for Pasteurella multocida(P.multocida).Specific primers and fluorescent labeling probes were designed based on the sequences of five podoplanar genes of P.multocida hyaC-hyaD,bcbD,dcbF,ecbJ,and fcbD in the NCBI database.We adjusted the annealing temperature by gradient setting,optimized the primer and probe concentrations by matrix method,constructed standard curves,and performed specificity,sensitivity and reproducibility tests,and finally established mul-tiplexed TaqMan qPCR assays for these five genes.The results showed that the established assay had a good linear relationship between the amplification curves.The sensitivity of this method was high,10-100 times higher than that of ordinary PCR;the specificity was strong,and there was no amplification curve in the DNA detection of eight pathogenic bacteria such as Bacillus,Proteus mirabilis,Staphylococcus aureus,and Rhizoctonia rad iodurans.This assay had a good linear rela-tionship,and the coefficients of variation for Ct values of the inter-and intra-group reproducibility tests were all less than 3％,and the detection rate of this assay was 11.25％higher than the con-ventional PCR assay through the detection of 90 clinical samples.The method established in this study is able to detect P.multocida rapidly and sensitively,which is important for its rapid clinical and laboratory diagnosis.

Exosomes are extracellular vesicles derived from the bilayer membrane structure of the cell. It has been reported that the contents of some miRNA, mRNA, lncRNA and protein in exosomes are different between renal cell carcinoma patients and healthy controls, and the differences are statistically significant. These substances in renal cell carcinoma exosomes may be helpful for the diagnosis of renal cell carcinoma which may improve the early diagnosis rate of renal cancer. This article reviews the research progress of exosomes in the diagnosis of renal cell carcinoma.

Objective To explore the safety and mid-term efficacy of autologous hamstring tendon implantation in the treatment of severe anterior vaginal wall prolapse.Methods We performed a prospective single arm clinical study.From May 2021,pelvic organ prolapse(POP)patients with severe anterior vaginal wall prolapse as the main cause who had symptoms and required surgical treatment were included.The patient was fully informed and voluntarily selected autologous hamstring tendon implantation and high sacral ligament suspension.Postoperative follow-ups were carried out on the Pelvic Organ Prolapse Quantification(POP-Q),Pelvic Floor Distress Inventory-Short Form 20(PFDI-20),postoperative satisfaction score,and Patient Global Impression of Improvement(PGI-I).Function of the lower limb on the tendon removal side,as well as postoperative complications and re-operations were recorded.Results The operation time of tendon removal was(19.7±8.3)min,the operation time of pelvic floor was(122.1±37.8)min,the median intraoperative bleeding volume was 70 ml(range,50-400 ml),and there was no intraoperative co-morbidity or postoperative fever.A total of 12 cases were followed up for(26.4±2.5)months.The measured values of Aa,Ba,and C were 3(-1-3),5(2-10),and 4(-1-10)before operation and-3(-3-3),-3(-3-3),and-6(-6-3)at 24 months after operation,respectively,with significant difference(P＜0.05).The PFDI-20 scores of the 12 patients before surgery and at 24 months after surgery were 88.0 points(range,16.7-204.2 points)and 8.3 points(range,0-32.3 points),respectively,with significant difference(Z=-2.803,P=0.005).The PGI-I questionnaire showed 11 patients with significant improvement in postoperative symptoms and 1 patient with improvement.The satisfaction scores at 6 and 24 months after surgery were(4.8±0.4)points and(4.6±0.7)points,respectively.One patient experienced vaginal prolapse at 12 months after surgery,with a Ⅲ degree prolapse of the anterior wall and vaginal vault,the recurrence rate being 8.3％(1/12).Two patients had pulmonary embolism at 9 d and 2 weeks after surgery,with Clavien-Dindo Ⅱ and Ⅲ grades,and recovered after outpatient and hospitalization treatment.One patient was found fascia exposure at the vagina,and had improvement with medication treatment.All the patients had good wound healing at the tendon removal site,with normal muscle strength and lower limb activity.No re-operation was required due to recurrence or complications of tendon surgery.Conclusions Autologous hamstring tendon implantation is safe in the treatment of severe anterior vaginal wall prolapse with satisfactory mid-term efficacy.Before surgery,it is necessary to educate patients on lower limb exercise to prevent complications of venous thrombosis.

Objective:Employing the cascade care model, this qualitative study explores determinants influencing the cascading care stages of hypertension and diabetes by interviewing various stakeholders.Methods:In July 2023, purposive sampling was employed to recruit participants from Gongyi and Wugang cities in Henan Province, and Linqu County in Weifang City, Shandong Province. Semi-structured in-depth interviews were conducted with representatives of policymakers, healthcare institution managers, providers, and patients with hypertension and diabetes.And thematic analysis was performed using both inductive and deductive approaches.Results:A total of 82 individuals were interviewed, with an age range of (53.8±12.0) years, among which 48 (58.5%) were male; including 5 policymakers, 10 institutional managers, 20 healthcare providers, and 47 patients with hypertension and diabetes. The study identified both barriers and facilitating factors at the patient, healthcare provider, and system levels across various stages: awareness, screening, diagnosis, treatment, long-term management, and control of hypertension and diabetes.Conclusion:By delineating and analyzing the barriers and facilitators at each stage of hypertension and diabetes care, this study lays the groundwork for the development of effective, feasible, and sustainable implementation pathways, with significant implications for the enhanced management of hypertension and diabetes in China.

Objective:To employ qualitative research methods to evaluate the sustainability of the Shandong-Ministry of Health Action on Salt and Hypertension (SMASH) interventions and their influencing factors.Method:In September 2023, interviewees meeting the inclusion criteria were recruited through purposive sampling in Jinan, Shandong Province. A semi-structured interview guide was designed based on the CFIR and RE-AIM frameworks. Personal in-depth interviews and focus group discussions were conducted to gather insights on the feasibility, effectiveness, and sustainability of the project interventions from various stakeholders, including representatives from the government, food manufacturers, restaurants, academia, and residents.Results:A total of 15 individuals participated in in-depth interviews, involving six representatives from food manufacturers, four from restaurants, three from the government, and two from academia. There were four focus group discussions with 30 residents. The study found that at the individual resident level, health awareness and the availability of sodium reduction tools in the market could affect their salt reduction practices. For food manufacturers and restaurants, consumers′ preferences, technical challenges in reformulation, and government support were key factors determining the smooth progress of their salt reduction efforts. At the governmental level, multi-sectional coordination, chronic disease management demonstration areas, and the impact of the pandemic were the main factors influencing the implementation of sodium reduction interventions.Conclusion:Future endeavours should strengthen long-term management and optimise the complex influencing factors associated with intervention measures. This will be essential in sustaining and expanding the positive health outcomes achieved through the Shandong population sodium reduction strategy.
