Objective To explore the epidemiological characteristics of gouty arthritis in Northwest China from 2023 to 2025, and to formulate preventive intervention measures. Methods By retrospectively analyzing the case data of medical institutions in Northwest China from January 2023 to June 2025 (a total of 8 139 cases), the incidence trend and population distribution characteristics of gouty arthritis in this area were analyzed. Multivariate logistic regression analysis was performed to identify risk factors. Results From 2023 to 2025, the prevalence rate of gouty arthritis in adult residents in Northwest China was 3.74% (304/8 139). Among the sites affected by gouty arthritis, the metatarsophalangeal joint accounted for the highest proportion (P<0.05). From the perspective of age distribution, the prevalence rate was the highest in 40-59 years old group (5.90%), followed by 66-80 years old group (4.21%) and >80 years old group (2.75%). The incidence rate in 40-65 years old group was higher than that in the other age groups (P<0.05). High blood uric acid and creatinine, alcohol drinking, obesity, high purine diet, concurrent chronic kidney disease and metabolic syndrome were risk factors affecting gouty arthritis in Northwest China (P<0.05). Conclusion High blood uric acid level, high creatinine level, alcohol drinking, obesity, high purine diet, concurrent chronic kidney disease and metabolic syndrome are risk factors influencing gouty arthritis in Northwest China. Based on the above factors, this study proposes comprehensive prevention strategies from the individual, community and public health levels to provide a scientific basis for reducing the incidence rate of gouty arthritis.

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.

Objective To explore the effect of scalp combined with intradermal-needle acupuncture synchronized rehabilitation ther-apy on upper limb motor function in stroke patients.Methods From December,2022 to December,2023,144 stroke patients with upper limb motor dysfunction in the Affili-ated Hospital of Shandong University of Traditional Chinese Medicine were randomly divided into control,intra-dermal-needle,scalp-acupuncture and acupuncture groups(36 cases repectively).All groups received convention-al treatment and upper limb rehabilitation training,the intradermal-needle group added intradermal-needle thera-py,the scalp-acupuncture group added scalp-acupuncture therapy,and the acupuncture group added both scalp-and intradermal-needle therapies,for four weeks.They were assessed with Fugl-Meyer Assessment-Upper Ex-tremities(FMA-UE),Wolf Motor Function Test(WMFT)and modified Barthel Index(MBI)before and after treatment.Twenty cases were selected randomly from each group,fractional anisotropy(FA)values and ratio of fractional anisotropy(rFA)of the lesion area and the posterior limb of the internal capsule were also measured with diffusion tensor imaging.Results Two cases dropped out in both the control group and the intradermal-needle group,while one case dropped out in both the scalp-acupuncture group and the acupuncture group.All groups showed significant improvement in FMA-UE,WMFT and MBI scores,as well as in the FA and rFA values of the lesion area and the posterior limb of the internal capsule(t>5.532,P<0.001)after treatment.The acupuncture group demonstrated the greatest pre-to post-treatment differences in FMA-UE scores,lesion-area FA and rFA values,and posterior-limb rFA val-ues compared with the other three groups(|Z|>3.256,P<0.05),and more WMFT and MBI improvements than those of the intradermal-needle group and the control group(|Z|>5.483,P<0.001).A significant interaction ef-fect was observed between intradermal and scalp acupuncture in improving FMA-UE scores(partial η2=0.035,P=0.029).The change in FMA-UE scores was positively correlated with the change in FA values of the posteri-or limb of the internal capsule(r>0.453,P<0.05)across four groups.Conclusion Scalp combined with intradermal-needle acupuncture synchronized rehabilitation therapy can more effec-tively improve upper-limb motor function in stroke patients,which may associate with the recovery of internal capsule.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.
