Objective To investigate the relationship between the comorbidity of dyslipidemia, hypertension and diabetes and lifestyle of adult residents in Hebei Province in 2018, and to provide reference for the development of chronic diseases prevention measures. Methods Using data from the surveillance of chronic diseases and their risk factors among adults in Hebei in 2018, 7 711 permanent residents aged ≥18 years were selected as the research subjects. Multivariate logistic regression analysis was used to analyze the relationship between the comorbidity of dyslipidemia, hypertension, and diabetes and lifestyle in adult residents. Results A total of 7 711 subjects aged ≥18 years were included in 2018. The comorbidity rates of hypertension and dyslipidemia, diabetes and dyslipidemia, and hypertension and diabetes were 16.88%, 7.91%, and 8.13%, respectively. The comorbidity rate of hypertension, diabetes, and dyslipidemia was 22.65%. These comorbidity rates increased with age and BMI. Multivariate logistic regression results showed that male, age, overweight/obesity, physical inactivity, daily sedentary behavior time ≥5 hours, and sleep problems were risk factors for the comorbidity of the "three highs". Conclusion The prevalence of the "three highs" comorbidities is relatively high in Hebei Province, and there are multiple common risk factors. Maintaining a healthy lifestyle and implementing comprehensive prevention and control measures are the key to improving the health level of residents.

Objective To analyze the prevalence of hyperuricemia (HUA) among adults in Hebei Province and its influencing factors related to comorbidities with ^“three highs^”, and to provide a theoretical basis for the prevention and control of HUA and multi-disease co-management. Methods Data were derived from the 2018 China Chronic Disease and Risk Factors Surveillance program conducted in Hebei Province. A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥18 years. All statistical analyses were adjusted for complex weighting. Design-based logistic regression was employed to analyze factors influencing HUA prevalence, and ordinal logistic regression was used to analyze the influencing factors of HUA patients and their comorbidity with ^“three highs^”. Results The prevalence of HUA among adults in Hebei Province was 10.42%, with males showing higher rates than females (P<0.05). The highest prevalence of HUA was observed in the 18-39 age group, followed by a declining trend, and a resurgence in those aged ≥70 (P<0.05). Among HUA patients with comorbidities, isolated HUA, 1 comorbidity, 2 comorbidities, and 3 comorbidities accounted for 13.94%, 33.33%, 39.17%, and 13.56%, respectively. HUA combined with hypertension and dyslipidemia represented the highest proportion (31.07%). Analysis of the influencing factors of HUA revealed that higher education levels, obesity, central obesity, and dyslipidemia increased the risk of HUA (P<0.05). Ordinal logistic regression analysis of HUA combined with three highs showed that HUA patients aged ≥50 years, overweight individuals, and those with chronic kidney disease had a higher number of patients with three highs (P<0.05). Conclusion HUA exhibits insidious onset, and it is recommended to include uric acid testing in routine physical examinations. Targeted prevention measures, such as early uric acid testing and health education, should be implemented by Hebei authorities for populations with higher education levels, obesity, central obesity, and dyslipidemia to reduce HUA incidence. Additionally, health education and regular medical check-ups are recommended for overweight HUA patients and those with chronic kidney disease to prevent comorbidities and alleviate disease burden.

Antibody (Ab) humanization is critical to reduce immunogenicity and enhance efficacy in the preclinical phase of the development of therapeutic Abs originated from animal models. Computational suggestions have long been desired, but available tools focused on immunogenicity calculation of whole Ab sequences and sequence segments, missing the individual residue sites. This study introduces Site-specific Immunogenicity for Therapeutic Antibody (SITA), a novel computational framework that predicts B-cell immunogenicity score for not only the overall antibody, but also individual residues, based on a comprehensive set of amino acid descriptors characterizing physicochemical and spatial features for antibody structures. A transfer-learning-inspired framework was purposely adopted to overcome the scarcity of Ab-Ab structural complexes. On an independent testing dataset derived from 13 Ab-Ab structural complexes, SITA successfully predicted the epitope sites for Ab-Ab structures with a receiver operating characteristic (ROC)-area unver the ROC curve (AUC) of 0.85 and a precision-recall (PR)-AUC of 0.305 at the residue level. Furthermore, the SITA score can significantly distinguish immunogenicity levels of whole human Abs, therapeutic Abs and non-human-derived Abs. More importantly, analysis of an additional 25 therapeutic Abs revealed that over 70% of them were detected with decreased immunogenicity after modification compared to their parent variants. Among these, nearly 66% Abs successfully identified actual modification sites from the top five sites with the highest SITA scores, suggesting the ability of SITA scores for guide the humanization of antibody. Overall, these findings highlight the potential of SITA in optimizing immunogenicity assessments during the process of therapeutic antibody design.

Financial incentives， as an intervention in behavioral therapy， have been proven to be beneficial in many health behaviors， such as drug addiction treatment， long-term antiviral therapy， and the prevention and treatment of chronic diseases. At present， typical financial incentive schemes mainly include commitment contracts and lottery-based models. Key factors in the design of such interventions include the adaptability of behavioral economic principles and medication behavior， the effectiveness and cost-effectiveness of design scheme， and the acceptability of intervention population. Although financial incentives have accumulated rich experience in health behavior interventions abroad， research on medication adherence remains limited， with existing intervention scheme design and mechanism constraints， and their effectiveness potentially varying across different cultural and social environments. China should explore practical models of financial incentives to enhance medication adherence, considering patients’ medication patterns and socio-cultural factors.

The incidence and mortality of colorectal cancer （CRC） in China have been on a steady rise. Current therapeutic approaches can curb the progression of CRC to a certain extent， but issues such as toxic side effects， high metastasis rate， and high recurrence rate cannot be ignored. In recent years， alkaloid components derived from traditional Chinese medicine （TCM） have demonstrated tremendous potential in the prevention and treatment of CRC due to their diverse structures， complex mechanisms， and broad biological activities. Representative alkaloids such as matrine， berberine and evodiamine exert anti-CRC effects through multiple pathways： regulating signaling pathways including Wnt/β-catenin， nuclear factor-κB， signal transducer and activator of transcription 3， and phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin； inhibiting the proliferation， migration， and invasion of CRC cells； inducing cell apoptosis and autophagy； arresting the cell cycle progression； regulating the gut microbiota； suppressing cellular glycolysis； and inducing ferroptosis.

Objective To explore the efficacy of ozone gas bath on necrotizing fasciitis after debride-ment.Methods Fifty patients with necrotizing fasciitis who underwent debridement in the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from January 2020 to July 2024 were selected and divided into control group(25 cases)and observation group(25 cases)according to random number table method.The control group was given routine dressing change(normal saline,povidone iodine,hydrogen per-oxide,metronidazole sodium chloride injection),and the observation group was treated with ozone gas bath.The clinical efficacy,pain scores,laboratory indicators,postoperative complications,and total hospital days of the two groups were compared before and after treatment.Results Compared with the control group,the ob-servation group had a higher total effective rate(92.0%vs.68.0%),lower numerical rating scale for pain(NRS)scores at 1 week postoperatively,2 weeks postoperatively,and before discharge,as well as lower levels of WBC,C reactive protein(CRP),and procalcitonin(PCT),and a lower total incidence of complications(52.0%vs.80.0%).The hospital stay was shorter[(22.40±2.06)d vs.(29.28±2.28)d)],with statistical-ly significant differences(P<0.05).Conclusion Ozone gas bath can reduce postoperative pain and promote recovery in necrotizing fasciitis after debridement.

Objective To investigate the predictive value of serum interleukin-17(IL-17)combined with eotaxin-3 for poor prognosis in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods A total of 213 patients with AECOPD admitted to Beijing Municipal Armed Police Force Hospital from May 2018 to July 2023 were selected as the disease group.According to the prognosis of patients,they were divided into good prognosis group(133 cases)and poor prognosis group(80 cases).At the same time,205 physical examination healthy people in Beijing Municipal Armed Police Force Hospital were selected as the healthy group.The serum levels of IL-17 and eotaxin-3 were detected by enzyme-linked immu-nosorbent assay.The clinical data of poor prognosis group and good prognosis group were compared.Pearson correlation analysis was used to analyze the correlation between serum IL-17 level and eotaxin-3 in AECOPD patients.Multivariate Logistic regression analysis was used to analyze the related factors affecting the progno-sis of AECOPD patients.The receiver operating characteristic(ROC)curve was used to evaluate the predic-tive value of serum IL-17 and eotaxin-3 levels for the prognosis of AECOPD patients.Results Compared with the healthy group,the serum levels of IL-17 and eotaxin-3 were increased in the disease group(P<0.05).Compared with the good prognosis group,the poor prognosis group had significant increases in serum IL-17 and eotaxin-3 levels(P<0.05).Serum IL-17 level was positively correlated with eotaxin-3 in AECOPD pa-tients(r=0.537,P<0.001).There were significant differences in Global Initiative for Chronic Obstructive Lung Disease(GOLD)grade,blood oxygen partial pressure(PaO2)and carbon dioxide partial pressure(PaCO2)between the poor prognosis group and the good prognosis group(P<0.05).GOLD grade,PaCO2,serum IL-17 and eotaxin-3 levels were risk factors for poor prognosis in patients with AECOPD(P<0.05),and PaO2 was a protective factor for poor prognosis in patients with AECOPD(P<0.05).The area under the curve of serum IL-17 and eotaxin-3 combined to predict the prognosis of AECOPD patients was 0.885,the sensitivity was 80.00%,and the specificity was 83.46%,which was better than that of IL-17 and eotaxin-3 a-lone(Zcombiation-IL-17=4.045,P<0.001,Zcombiation-eotaxin-3=3.254,P=0.001).Conclusion The serum levels of IL-17 and eotaxin-3 are increased in AECOPD patients.The combination of IL-17 and eotaxin-3 has predictive value for the prognosis of AECOPD patients.

Objective To investigate the association between the Chinese visceral adiposity index (CVAI) and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among elderly people in Hebei Province. Methods In 2020, a stratified multi-stage random sampling was used to conduct questionnaire survey, physical examination and laboratory detection among permanent residents of 10 monitoring sites in Hebei Province. Logistic regression was used to analyze the association between CVAI and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. The area under the ROC curve (AUC) was used to evaluate the predictive value of CVAI for diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. Results The detection rates of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension were 19.8%, 74.6%, 78.2%, and 16.2%, respectively. Multivariate logistic regression analysis showed that compared with the lowest quartile of CVAI group Q1, the OR (95% CI) of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension in the highest quartile Q4 group were 3.55 (2.58~4.89), 2.52 (1.92~3.31), 3.09 (2.31~4.12), and 4.92 (3.40~7.12), respectively. The ROC curve results showed that CVAI had the best predictive value in the diagnosis of diabetes with hypertension, and the optimized critical values in males and females were 128.54 and 141.88, respectively. Conclusion The detection rates of diabetes mellitus and hypertension are high in the elderly population in Hebei Province. CVAI is positively associated with the risk of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among the elderly in Hebei. CVAI has the strongest prediction ability for diabetes with hypertension.

OBJECTIVE To analyze the current status of hospital-acquired infections(HAI)in cancer patients in Henan Cancer Hospital,and explore the application of Case Mix Index(CMI)based on disease diagnosis-related groups(DRG)in the evaluation of HAI risks.METHOD Data on HAI of patients in cancer hospitals in Henan Province from Jun.2023 to Jun.2024 were statistically analyzed,including incidence rates,distribution of infec-tion sites and composition ratios of pathogens,high-risk departments were identified by CMI-adjusted 1 000-day incidence rates of HAI infections,and the current status of HAI in cancer patients were analyzed.RESULTS The incidence of HAI in cancer patients was 1.67％(4 315/259 087),and the incidence rate of HAI in 1 000 days was 2.46 per 1000.The sites of infection were mainly the respiratory tract,the abdominal cavity,the surgical sites and the bloodstream.A total of 2 381 strains of pathogens were cultured and isolated,including 1 570 strains of gram-negative bacteria,638 strains of gram-positive bacteria and 173 strain s of fungi,and the top five strains de-tected were Escherichia coli(24.49％),Klebsiella pneumoniae(15.41％),Pseudomonas aeruginosa(9.11％),Staphylococcus aureus(8.86％)and Staphylococcus epidermidis(4.66％).After CMI adjustment,the order of decreasing was dominated by surgical departments,while the order of increasing was dominated by non-surgical departments,and the top five departments with the highest adjusted incidence rates were Orthopedics and Soft Tissue department,Hematology department,Hepatobiliary Surgery department,General Surgery department and Urology department.CONCLUSIONS In the prevention and control of HAI in cancer patients,attention should be given to the gram-negative bacteria,and close monitoring of infections in the respiratory tract,abdominal cavity,and surgical sites is essential.This study uses the CMI to adjust the HAI incidence rate of cancer patients in order to identify high-risk departments that currently require focused management,it also analyzes the DRGs codes with a highest proportion of HAI in each department,with a particular focus on patients in these high-risk groups,and it aims to avoid and minimize the occurrence of HAI among cancer patients as much as possible through refined DRGs analysis and targeted prevention and control measures.
