OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori （Hp） infection， and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1， 2021 to December 1， 2024 were selected and randomly divided into control group and study group， with 100 cases in each group. The control group was treated with classic quadruple therapy regimen （Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets）. The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat （ITT） and per-protocol （PP） analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses， there was no significant difference of Hp eradication rates between the two groups （P＞0.05）. There was no significant difference in incidence of mild to moderate adverse reactions between the two groups （P＞0.05）. BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment （P＜0.05）. CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease.

Objective: To investigate the occupational health literacy (OHL) level and its influencing factors of key populations in Jinhua City, Zhejiang Province, so as to provide a basis for promoting occupational health. Methods: The front-line workers of 7 secondary industry enterprises (institutions) and 15 tertiary industry enterprises (institutions) in Jinhua City were selected from April to October 2023 using a stratified random cluster sampling method. Date of gender, age, length of service, and OHL were collected using the National Occupational Health Literacy Monitoring Survey for Key Population Personal Questionnaire. Factors affecting OHL level among key populations were identified using multivariable logistic regression model. Results: A total of 3 305 people were investigated, including 1 750 males (52.95%) and 1 555 females (47.05%). The median age and the length of service were 37 (interquartile range, 17) and (interquartile range, 9) years, respectively. The level of OHL was 45.63%. Multivariable logistic regression analysis identified gender (female, OR=1.675, 95%CI: 1.428-1.964), educational level (junior high school, OR=1.499, 95%CI: 1.089-2.063; high school, OR=1.905, 95%CI: 1.361-2.667; junior college, OR=4.065, 95%CI: 2.858-5.782; bachelor degree and above, OR=5.087, 95%CI: 3.597-7.194), personal monthly income (3 000-< 5 000 yuan, OR=1.373, 95%CI: 1.035-1.821; 5 000-<7 000 yuan, OR=1.653, 95%CI: 1.230-2.220; ≥7 000 yuan, OR=1.798, 95%CI: 1.322-2.447) and length of service (2-<6 years, OR=1.265, 95%CI: 1.032-1.551; 6-<11 years, OR=1.517, 95%CI: 1.184-1.943; ≥11 years, OR=1.337, 95%CI: 1.040-1.719) as factors affecting OHL level among key populations.

The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

Background: The genus Atractylodes, native to East Asia, encompasses several species that serve as sources for the widely used traditional Chinese medicines Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma. However, the international trade arouses concern regarding potential confusion and misidentification of Atractylodes species. Objective: A comprehensive understanding of the chemical diversity is crucial for ensuring the quality and exploring the potential variations in medicinal efficacy of Atractylodes. Methods: The GC-MS/MS-based metabolomics and multivariate statistical analysis identified 589 differentially accumulated metabolites across 5 Atractylodes species. Results: A total of 150 metabolites were predicted as potential chemical markers for species differentiation and quality assessment of Atractylodes. According to the metabolic profiles, the species of Atractylodes can be roughly classified into three categories: A. lancea and A. coreana with the volatile oil components being mainly atractylodin and β-eudesmol; A. macrocephala with the biomarker being atractylon; and A. japonica and A. carlinoides lying between the two categories above. Conclusions: Metabolomic results indicated that the metabolic profiles of A. carlinoides and A. macrocephala were similar and distinct from those of the other three species. Sesquiterpenoids were the main chemical components in the rhizome of A. carlinoides, which indicated the potential medicinal value of this plant.

Objective:To investigate the trend of radiological diagnostic examination frequency and the related influencing factors in a general hospital in recent four years.Methods:The hospital information system and the radiology information system were used to collect the information on the numbers of the outpatients, the emergency patients, and the inpatients and the radiology examination information from 2019 to 2022. The examination frequency and proportion of various imaging equipment were counted by using the perspective table of data, and the examination items and the proportion of the radiological diagnostic examinations were calculated. The positive rates of the radiological examinations were measured from 2019 to 2022. The gender and age distribution of the patients were analyzed. Spearman correlation analysis was used to analyze the relationships between the numbers of the patients undergoing radiological examinations and the numbers of the outpatients, emergency patients and the inpatients.Results:The annual frequency of radiological diagnostic examinations from 2019 to 2022 were 307 306, 245 418, 317 250 and 325 625, respectively, with a total of 1 195 599. Among them, the proportions of CT, X-rays, bedside X-rays, bone density, gastrointestinal imaging and mammography were 59.74%, 38.04%, 1.39%, 0.42%, 0.21% and 0.19%, respectively. In each year, the proportion of CT in all radiological diagnostic examinations was 49.58%, 63.40%, 60.40% and 65.20%, respectively. The frequency of emergency CT and emergency chest CT was correlated with the number of emergency patients( r =0.63, 0.61, P<0.05), and the frequency of non-emergency CT was correlated with the number of outpatients and inpatients ( r =0.61, 0.66, P<0.05). The positive rates of the CT examinations were higher than 80% except the lowest of 79.95% in 2021. Conclusions:Radiological examinations especially CT examinations have increased significantly, and played an important role in the diagnosis of diseases. However, attention should be paid to the Justification of the CT examinations. Timely statistical analysis of radiological examination information can provide data supports and references for scientific management of radiological examinations.

Objective To observe the effect of coronary reperfusion therapy on the differential ex-pression of plasma exosomal miRNAs in patients with acute myocardial infarction(AMI).Meth-ods Three elderly male AMI patients undergoing coronary reperfusion therapy in our hospital from October to November 2022 were recruited in this study.The venous blood samples were col-lected at admission and 2 and 24 h after recanalization.MiRNA-sequencing was used to screen the differentially expressed miRNAs which were commonly expressed in the plasma exosomes of the 3 patients.Bioinformatics analysis was performed on the target genes,and then the differentially expressed miR-499a-5p was verified by qPCR.Results Compared with the plasma exosomal miRNAs at admission,there were 418 up-regulated and 406 down-regulated miRNAs at 2 h after operation,and 320 up-regulated and 225 down-regulated miRNAs at 24 h after operation(P＜0.05);Compared with the miRNAs at 2 h after operation,there were 344 up-regulated and 350 down-regulated ones at 24 h after operation(P＜0.05).Kyoto Encyclopedia of Genes and Ge-nomes enrichment analysis showed that the differentially expressed miRNAs were enriched in phosphatidylinositol-3-kinase-protein kinase B,hypoxia-inducible factor 1,and vascular smooth muscle contraction pathways.Gene Ontology analysis indicated that the molecular functions of dif-ferentially expressed miRNA target genes were mainly enriched in protein binding and DNA bind-ing;cellular components were mainly enriched in cell membrane and cytoplasm;and biological processes were mainly enriched in signaling and transcription of DNA templates.The miR-499a-5p level was significantly lower at 2 h postoperatively than at admission[(0.577±0.020)vs(1.000± 0.023),P＜0.05],and at 24 h postoperatively than at 2 h postoperatively[(0.068±0.006)vs(0.577±0.020),P＜0.05].Conclusion Plasma exosomal miRNAs can be used as a biomarker for early diagnosis of elderly AMI patients and for predicting the efficacy of reperfusion therapy.
