ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

Objective:To analyze the epidemiological characteristics of cases involving monkey injuries at medical institutions surrounding Qianlingshan Park in Guiyang City, and to provide a reference basis for preventive measures to reduce monkey injuries and standardized post-exposure treatment.Methods:A retrospective cross-sectional study was conducted, collecting 1 900 cases of monkey-induced injuries in Qianlingshan Park treated at the outpatient clinic of Guizhou Provincial Center for Disease Control and Prevention and the Department of Surgery at Qianling Hospital, Guiyang City, from 2021 to 2024. Statistical analysis was performed using Pearson′s chi-square test.Results:Total of 1 900 cases of monkey-related injuries in Qianlingshan Park were collected from 2021 to 2024. The exposure time distribution exhibited significant seasonality, with 48.58% of cases occurring during July and August, totaling 923 cases, indicating a peak in the summer. There were 774 male patients and 1 126 female patients, with a ratio of 1∶1.45.and significant differences were observed between different age groups and genders (χ2=195.00, P<0.001), with the highest number of cases occurring in the 0-9 and 20-29 age groups, accounting for 22.05%(419 cases) and 21.79%(414 cases), respectively. The upper limbs were the most common injury site, accounting for 50.84% of the total cases(966 cases in total), with significant differences between gender and injury location (χ2=22.00, P<0.001), Among females, the proportion of injuries to the upper and lower limbs (30.11% and 16.47%, respectively) was higher than that among males (20.74% and 8.63%, respectively). The majority of injuries were classified as Grade Ⅲ, making up 57.38% of cases(1 069 cases in total). Self-treatment after exposure was the most common approach(60.44%), with significant differences observed between wound severity and treatment method (χ2=6.90, P=0.032), Patients with Grade Ⅱ and Grade Ⅲ wounds were more likely to choose self-management (26.84% and 33.23%, respectively) than outpatient management (15.14% and 24.15%). Approximately 98.05% (1 863 cases) of monkey-injured patients had received rabies vaccinations. Conclusions:This study analyzes monkey-related injuries in Qianlingshan Park from 2021 to 2024, clarifying the temporal distribution of injuries, demographic characteristics, injury sites, and treatment methods. The findings provide references for optimizing human-monkey conflict management and the prevention and control of zoonotic diseases in urban ecological parks.

To investigate the levels and clinical significance of serum microRNA ( miR) -146a, miR-145, T-helpertype17 (Th17)/regulatory T cell (Treg) in children with respiratory syncytial virus (RSV) infectious pneumonia. The clinical data of 200 children with RSV infectious pneumonia admitted to Nantong Maternal and Child Health Hospital from June 2020 to June 2023 were retrospectively collected as the study group. At the same time, 200 children with mycoplasma pneumonia were selected as the common pneumonia group and 200 healthy children were selected as the healthy group. The levels of serum inflammatory factors [interleukin-6 (IL-6), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α)] were detected by enzyme-linked immunosorbent assay. The expression levels of serum miR-146a and miR-145 were detected by RT-qPCR. The levels of Th17/Treg were detected by flow cytometry. The levels of miR-146a, miR-145, Th17/Treg and serum inflammatory factors were compared among the three groups. Pearson method was used to analyze the correlation between miR-146a, miR-145, Th17/Treg and serum inflammatory factors in children with RSV infectious pneumonia. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of miR-146a, miR-145, Th17/Treg in children with respiratory syncytial virus infection pneumonia. The results showed that in the study group, miR-146a (2.01±0.58), miR-145 (1.81±0.46), Th17/Treg (1.09±0.31), IL-6 (7.82±2.11) ng/L and TNF-α (9.82±2.96) ng/L were higher than those in the common pneumonia group miR-146a (1.49±0.42), miR-145 (1.43±0.31), Th17/Treg (0.77±0.24), IL-6 (5.89±1.32) ng/L, TNF-α (7.34±2.32) ng/L and healthy group miR-146a (1.25±0.19), miR-145 (1.19±0.16), Th17/Treg (0.38±0.09), IL-6 (4.52±1.04) ng/L, TNF-α (5.39±1.07)ng/L. The levels of the above indexes in the common pneumonia group were higher than those in the healthy group, and the differences were statistically significant ( F=183.543, 175.938, 617.182, 226.657, 193.459, P<0.05). In the study group, IFN-γ (14.18±3.25) pg/ml was lower than that in the control group (19.52±5.13) pg/ml, but higher than that in the healthy group (9.77±2.40) pg/ml, and the difference was statistically significant ( F=335.432, P<0.05). Pearson correlation analysis showed that miR-146a, miR-145 and Th17/Treg were positively correlated with IL-6 and TNF-α ( P<0.05), but negatively correlated with IFN-γ ( P<0.05). ROC curve results showed that the area under the curve (AUC) of miR-146a, miR-145 and Th17/Treg in the diagnosis of RSV infectious pneumonia was 0.767, 0.762 and 0.790, respectively, while the combined detection of the three was 0.904. In conclusion, the levels of miR-146a, miR-145 and Th17/Treg are highly expressed in children with RSV infectious pneumonia, and are closely related to the inflammatory response of children. The combined detection of the three may have certain application value in the auxiliary diagnosis of RSV infectious pneumonia.

Objective:To compare the effects of leukocyte-poor platelet-rich plasma (Lp-PRP) and leukocyte-rich platelet-rich plasma (Lr-PRP) on dorsal wound healing in rats.Methods:Thirty-six male Sprague-Dawley rats were randomly divided into Lp-PRP group, Lr-PRP group and control group, each containing twelve rats. Venous blood was drawn and the Lp-PRP and Lr-PRP were prepared separately using a centrifugal method. Circular full-thickness skin defect wounds (15 mm in diameter) were created on the backs of the rats in the three groups. The wounds were then treated with 100 μl Lp-PRP, Lr-PRP and saline, respectively. At 7 and 14 days post-operation, the wounds were photographed, and Image J software was used to calculate the wound area rate (postoperative wound area/wound area at modeling time × 100%). At 14 days post-operation, the total neo-epithelium length and collagen deposition rate of the wounds were evaluated using HE and Masson staining, respectively. At 7 days post-operation, the relative expression of vascular endothelial growth factor (VEGF) in the wounds was detected by Western blotting, and the number of CD31 positive microvessels in the wounds was examined by immunohistochemistry. Statistical analysis was performed using SPSS 28.0. One-way analysis of variance (ANOVA) was used to compare the three groups, and Tukey’s test was used for pairwise comparisons. A significance level of P<0.05 was considered statistically significant. Results:Blood analysis revealed that the platelet concentrations in the prepared Lp-PRP and Lr-PRP were 4.1 times and 4.5 times that of whole blood, respectively ( P<0.01), with no significant difference between the two PRPs ( P>0.05). The leukocyte concentration in Lp-PRP was undetectable, while in Lr-PRP, it was 3.5 times that of whole blood ( P<0.01). The wound area rate at 7 and 14 days post-operation, the total neo-epithelium length and collagen deposition rate at 14 days post-operation, as well as the relative expression of VEGF and the number of CD31-positive microvessels at 7 days post-operation in the Lp-PRP and Lr-PRP groups were superior to those in the control group (all P<0.01). However, there was no significant difference between the two PRP groups (all P>0.05). Conclusion:Both Lp-PRP and Lr-PRP promote dorsal wound healing in rats by enhancing re-epithelialization, collagen deposition, and angiogenesis. The impacts of Lp-PRP and Lr-PRP on promoting wound healing are comparable and not influenced by the presence of leukocytes in PRPs.

Objective:To provide theoretical basis for strength and endurance training of waist and abdominal muscles and prevention of waist injuries in fighter pilots by exploring the muscle strength and work characteristics of the waist and abdominal flexor and extensor muscles in fighter pilots.Methods:Sixty male fighter pilots who were qualified for flight in aeromedical assessment, aged 24-46 years old, were randomly selected and divided into 24-30, 31-40, 41-46 years group. The Isomed2000 isokinetic dynamometer system was applied to measure the muscle strength and work performance of the abdominal and lumbar flexors and extensors of the fighter pilots with the angular velocities of 60°/s and 180°/s. The flexion and extension muscle peak torque, relative peak torque, flexion-extension ratio, and endurance ratio were compared among different age groups of pilots.Results:At the same angular velocity, the peak torque and relative peak torque of the lumbar and abdominal extensor muscles in fighter pilots were greater than those of the flexor muscles, with statistically significant differences ( t=7.01-9.13, all P<0.001). The peak torque and relative peak torque of the lumbar and abdominal flexor and extensor muscles significantly decreased with increasing test angular velocity ( t=13.63-17.25, all P<0.001). Under the angular velocity of 60°/s, there were no significant differences in the peak torque and relative peak torque of the flexor muscles among different age groups (both P>0.05); there were significant differences in the peak torque and relative peak torque of extensor muscles ( F=5.31, 6.61, P=0.008, 0.003) and 41-46 years groups were lower than the other 2 groups ( P=0.019, 0.003, 0.002, 0.004). Under an angular velocity of 180°/s, there were significant differences in the peak torque and relative peak torque of the waist and abdominal flexor and extensor muscles among different age groups ( F=3.82, 3.47, 3.83, 5.49, P=0.028, 0.043, 0.027, 0.008); the relative peak torque of the abdominal and lumbar flexor and extensor muscles in the 24-30 years group was higher than that in the 41-46 years group ( P=0.032, 0.006). The peak torque and the relative peak torque of the abdominal and lumbar flexor muscles in 31-40 years group were higher than those in 41-46 years group ( P=0.008, 0.013). The low qualification rate of peak torque ratio indicated the imbalance between flexor and extensor muscles and the poor endurance of abdominal and lumbar flexor and extensor muscles than that of flexor muscles. There was no statistically significant difference in the endurance ratio of the abdominal and lumbar flexor and extensor muscles among different age groups ( P>0.05). Conclusions:The balance between flexor and extensor muscles of waist and abdominal muscles should be paid more in fighter pilot′s fitness training. For the pilots older than 40 the training targeted to slow the muscles decline is necessary.
