ObjectiveTo investigate the first-diagnosed reporting rate and annual changing trends of chronic obstructive pulmonary disease (COPD) among adult residents in Changzhou City from 2020 to 2024, and to provide a scientific basis for the prevention and control of COPD in this region. MethodsData on first-diagnosed cases of COPD from 2020 to 2024 were collected from the Changzhou Health Data Management Platform, along with resident population data stratified by age group and sex for the corresponding years. Stratified analyses were conducted by diagnosis year, sex, and age group to calculate crude first-diagnosed reporting rate and age-specific first-diagnosed reporting rate. The age-standardized first-diagnosed reporting rate (ASFDRR) was calculated using data from the Seventh National Population Census of China (2020) as the standard population. A logarithmic-linear model was employed to estimate the average annual percentage change (AAPC) in ASFDRR, along with its 95%CI and P-value. ResultsFrom 2020 to 2024, a total of 12 925 first-diagnosed COPD cases of adult residents were reported in Changzhou City. The overall crude first-diagnosed reporting rate increased from 37.91/100 000 in 2020 to 100.68/100 000 in 2024. The overall ASFDRR rose from 116.83/100 000 in 2020 to 274.59/100 000 in 2024, with an AAPC of 26.55% (95%CI: 5.98%‒51.11%). Among these,9 831 new cases were male, with the crude first-diagnosed reporting rate increasing from 57.07/100 000 to 159.29/100 000, and the ASFDRR increasing from 92.54/100 000 to 223.82 / 100 000, with an AAPC of 27.58% (95%CI: 6.21%‒53.26%). There were 3 094 new female cases, with the crude first-diagnosed reporting rate rising from 19.53/100 000 to 45.39/100 000, and the ASFDRR increasing from 26.01/100 000 to 55.33/100 000, with an AAPC of 22.90% (95%CI: 5.19%‒43.59%). Both crude and age-standardized first-diagnosed reporting rates of COPD for the total population and different gender groups showed a statistically significant upward trend as age increased (all P<0.05). The reporting peaks were primarily concentrated in the 80 years old age group. ConclusionThe age-standardized first-diagnosed reporting rate of COPD in Changzhou City exhibited a rapid upward trend from 2020 to 2024. ASFDRR was higher in males than that in females, and the elderly population constituted the main reported group. This trend warrants close attention, emphasizing the need to strengthen screening, early intervention, and standardized management for high-risk populations.

Objective To analyze the clinical characteristics of measles cases in the measles elimination stage and to provide a scientific basis for the prevention, control, diagnosis and treatment of measles. Methods The descriptive epidemiological method was used to analyze the clinical characteristics of 442 confirmed measles cases in Hebei Province from 2018 to 2020. Results Among the 442 measles cases, the main symptoms were rash (96.61%), fever (90.50%), cough (56.11%), and Koplik spots (30.09%). Complications were mainly pneumonia (12.22%). There were significant differences in symptoms among different age groups (P < 0.05). The incidence of symptoms in children under 5 years old (except cough) was higher than that in other age groups. Immunization history had no significant impact on the symptoms of fever and rash (P > 0.05), but the incidence of symptoms such as cough, conjunctivitis, Koplik's spots and catarrhal rhinitis in the immunized group was lower than that in the non-immunized group (P < 0.05). The group with an interval of 0 days from fever to rash was the largest, and the proportion of people with an immunization history in the 0-day group (68.06%) was significantly higher than that in the 3-4-day group (49.44%) (P < 0.05). Pneumonia complications were mainly concentrated in children under 5 years old (87.03%), and most of the cases had a 0-dose immunization history (81.48%). Conclusion In the measles elimination stage, the incidence of fever and rash in cases is relatively high, while the incidence of Koplik spots is relatively low. The symptoms are more obvious in the younger age group. Vaccination can reduce the incidence of specific symptoms. The change in the time of rash appearance suggests that the diagnosis and treatment plan need to be adjusted. This study provides key data support for the formulation of measles prevention, control and treatment strategies.

Objective:To systematically integrate the work experience of medical and nursing staff in the remote home palliative care model, so as to provide a reference for improving remote home palliative care services.Methods:Qualitative studies on medical and nursing staff providing remote home palliative care were electronically searched in PubMed, Web of Science, Embase, ProQuest, CINAHL, PsycINFO, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to April 30, 2024. Literature quality evaluation was conducted using the Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The aggregative integration method was used to synthesize the findings.Results:Researchers repeatedly read, analyzed, and interpreted the 17 included literature, extracting 56 themes and summarizing eight new categories, and further synthesized three integrated results, namely, remote home palliative care provided patients with comprehensive physical, psychological, and mental care, as well as guidance and support for family members; remote home care helped to achieve full coverage of palliative care services; equipment limitations, information security risks, and incomplete processes restricted the development of remote palliative care.Conclusions:Remote home palliative care has improved patient care and family support capabilities, expanded service coverage, and promoted interdisciplinary collaboration. However, there are still issues such as equipment limitations, information security risks, and incomplete processes. Optimizing processes, improving safety mechanisms, and strengthening collaboration platforms will contribute to sustainable development.

Objective To analyze the operation of Measles Surveillance System (MSS) in Hebei Province, and to provide evidence for measles elimination. Methods Measles surveillance data was collected from the MSS from 2020 to 2023, and a modified weighted technology for order preference by similarity to an ideal solution (TOPSIS) method was used to evaluate the surveillance indexes of measles in Hebei Province. Results The operation quality of the measles surveillance system in Hebei Province was improved year by year, with the highest quality in 2023, and all the indicators reached the monitoring program standards. The quality of measles surveillance system was not balanced among cities, and the main influencing factor was the substandard sensitivity indicators. The quality of measles surveillance system was the highest in Baoding City and the lowest in Zhangjiakou City. Conclusion The measles surveillance system in Hebei province is running well, and the sensitivity of the surveillance system should be improved to keep the high-quality operation of the surveillance system.

Objective: To investigate the prevalence and influencing factors of dyslipidemia among residents in Changzhou City, Jiangsu Province, so as to provide insights into improving prevention and control strategies of dyslipidemia. Methods: Permanent residents aged 35 to 75 years were recruited based on the Early Screening and Comprehensive Intervention Project for High-risk Populations of Cardiovascular Disease in Changzhou City from 2016 to 2023. Demographic information, body mass index (BMI), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were investigated through questionnaire surveys, physical examinations and laboratory tests, and the prevalence of dyslipidemia were analyzed. Factors affecting dyslipidemia were identified using a multivariable logistic regression model. Results: A total of 22 447 residents were surveyed, including 9 142 males (40.73%) and 13 305 females (59.27%), and had a median age of 57.00 (interquartile range, 18.00) years. There were 7 535 cases of dyslipidemia, with a prevalence rate of 33.57%. The prevalence rates of low HDL-C, high TG, high TC, and high LDL-C were 22.27%, 15.89%, 4.06% and 2.27%, respectively. Multivariable logistic regression analysis showed that the residents who were male (OR=1.780, 95%CI: 1.645-1.924), had more than 50 000 yuan of annual household income (OR=1.215, 95%CI: 1.142-1.293), had higher educational level (junior high school/senior high school/technical secondary school, OR=1.138, 95%CI: 1.047-1.237; junior college and above, OR=1.232, 95%CI: 1.095-1.386), smoked frequently (OR=1.504, 95%CI: 1.369-1.653), were overweight (OR=1.763, 95%CI: 1.650-1.885) or obese (OR=2.351, 95%CI: 2.149-2.572), had hypertension (OR=1.478, 95%CI: 1.384-1.579) and diabetes (OR=1.706, 95%CI: 1.586-1.835) had a higher risk of dyslipidemia; while the residents who consumed alcohol at 4 times per week and more (OR=0.619, 95%CI: 0.557-0.688) had a lower risk of dyslipidemia. Conclusions The main types of dyslipidemia are low HDL-C and high TG among residents aged 35 years and above in Changzhou City. The prevalence of dyslipidemia is mainly associated with gender, annual household income, educational level, smoking, alcohol consumption, BMI, hypertension and diabetes.

Objective:To study the optimal anastomotic angle of end-to-side anastomosis autogenous arteriovenous fistula (AVF).Methods:A case-report and case-series design was used to obtain clinical data on 10 patients with diabetic nephropathy from Department of Nephrology, the 905th Hospital of the Chinese People′s Liberation Army Navy from June 2024 to February 2025. The models of "radial artery-cephalic vein" end-to-side anastomosis in the forearm with anastomotic angles of 30°, 40°and 50°were established. Numerical simulation was used to analyze the blood flow in the model, and to study the effect of different anastomotic angles on blood flow. Wall shear stress (WSS), cross section flow velocity and flow rate, and relative residence time (RRT) were studied in the model. The Whitney test with Holm correction was used to evaluate the difference in the median RRT between the three angle models.Results:At the moment of 0.65 s, the area fraction of low wall shear stress (LWSS) in the 30° model was 7.7%, which was reduced by 2.4% and 3.7% compared to the 40°and 50°models, respectively. At the time of 0.2 s, the area proportions of high wall shear stress (HWSS) in the 30°, 40°and 50°models were 54.4%, 43.9% and 37.4%, respectively. At 0.2 s, the maximum cross section flow velocity reached 4.07, 3.84 and 3.67 m/s for the 30°, 40°and 50°models, respectively. In the cycle, the maximum mean flow velocity for the 30°model reached 1.20 m/s. The mean flow rates of the 30°, 40°and 50°models in the J-5 cross section were 349, 316, and 328 ml/min, respectivly. For patient 6, the area proportions of the RRT>1 region were 11.97%, 14.84% and 15.22% for the 30°, 40°and 50°models, respectively.Conclusions:The optimal anastomotic angle of "radial artery-cephalic vein" for end-to-side anastomosis AVF surgery in patients with diabetic nephropathy is 40°.
