Objective To comprehensively analyze the current epidemic characteristics and disease burden of brucellosis in Tongliao City, and to provide a basis for the prevention and control strategy of brucellosis in Tongliao City. Methods The report data of brucellosis in Tongliao City from 2018 to 2023 were collected. Descriptive methods were used for data analysis, and the disability-adjusted life years and indirect economic losses were calculated. Results From 2018 to 2023, a total of 22 034 cases were reported in Tongliao City, with an average annual incidence of 136.17/100 000. The incidence was statistically different between men and women ( χ²=12.23, P=0.032). The majority of cases were farmers (94.25%), followed by herdsmen (1.67%). The age group was concentrated between 30-60 years old (79.30%), among which the majority of cases were in the 40-50 years group (6 883/22 034). The onset time had seasonal characteristics, and the peak period was from March to August (the seasonal index was between 115.40%-151.29%). In terms of regional distribution, cases were reported in all counties (banners). The average annual incidence was highest in Kulun Banner (233.85/100 000) and Zalut Banner (210.13/100 000), and lowest in Keerqin District (42.28/100 000) and Holingol City (31.87/100 000). The analysis of disease burden showed that a total of 677.55 person-years (YLD) were lost from 2018 to 2023, with an average annual loss of 112.92 person-years. The total indirect economic loss was 59.3576 million yuan, with an average annual loss of 9.892 9 million yuan, and the people over 60 years old had the lowest annual loss. Conclusion The overall brucellosis epidemic in Tongliao City has shown a fluctuating downward trend. The epidemic prevention and control should be strengthened in farmers, people aged 40-50 years old, and areas such as Zalut Banner and Kulun Banner to further control the epidemic of brucellosis.

Liver cirrhosis recompensation refers to the process in which patients with decompensated cirrhosis achieve the disappearance of decompensated complications and restoration of liver function and clinical phenotype to a compensated state after etiological treatment or symptomatic treatment. In recent years， with effective control of the etiology of cirrhosis and treatment or prevention of decompensated complications， the clinical significance of recompensation has gained increasing attention. This article elaborates on recompensation from the aspects of definition， diagnostic criteria， influencing factors， mechanisms affecting long-term prognosis， and clinical management strategies， and with reference to the latest research evidence， this article also discusses the core value of recompensation in improving quality of life and reducing the risk of end-stage events， in order to provide a basis for optimizing the comprehensive management of liver cirrhosis.

Objective: To analyze characteristics of iron-deficient blood donors, implement targeted interventions, and evaluate their effectiveness, thereby providing a reference for formulating blood donor recruitment and care strategies. Methods: Based on serum ferritin (SF) test results, the apheresis platelet donors were divided into the low SF group (n=90; 45 males and 45 females) and the normal SF group (n=651; 510 males and 141 females). The results of related indicators of the two groups were compared and analyzed. Interventions for the low SF group included extending the blood donation interval to at least 45 days (group A) and oral iron supplementation combined with the extended donation interval implemented in group A (group B). Pre-intervention and post-intervention SF results were compared. Results: For both male and female donors, serum iron levels were significantly lower in the low SF group than those of the normal SF group, while the levels of transferrin, unsaturated iron binding capacity (UIBC) and total iron binding capacity (TIBC) were higher in the low SF group compared to the normal SF group. Some indicators related to red blood cells showed changes, with more evident alterations in females than in males. Twenty-eight donors in group A and 39 donors in group B completed the study after intervention. SF value in group A was (18.32±8.09) μg/L at baseline and (26.21±17.30) μg/L after intervention. Similarly, SF value in group B was (15.87±7.69) μg/L at baseline and (26.24±15.55) μg/L after intervention. In both groups, SF values after intervention were significantly higher than baseline values. However, the magnitude of change did not significantly differ between groups A and B. Conclusion: Other related indicators in blood donors with low ferritin have also experienced some changes, suggesting that some blood donors may have entered the stage of iron-deficient erythropoiesis. Extending blood donation interval facilitates the recovery of iron storage in low-ferritin apheresis platelet donors. Blood stations should develop care strategies for apheresis platelet donors, including, at a minimum, the prolonged blood donation interval for donors with low ferritin.

Objective To analyze the feasibility of probiotics in delaying the progression of early Alzheimer's disease(AD)based on the changes of brain-gut-microbiota axis factors.Methods A total of 100 patients with early AD who visited Shaoxing 7th People's Hospital from December 2023 to December 2024 were selected and divided into control group(40 cases)and study group(60 cases)based on different treatment methods.The control group was treated with donepezil hydrochloride,while study group was treated with donepezil hydrochloride combined with probiotic preparations.The cognitive function,daily living ability,intestinal flora,and relative expression levels of brain-gut-microbiota axis factors,interleukin(IL)-6,tumor necrosis factor-α(TNF-α),5-hydroxytryptamine(5-HT),γ-aminobutyric acid(GABA),and lipopolysaccharide(LPS)/Toll-like receptor 4(TLR4)/nuclear factor-KB(NF-κB)axis factors were compared before and after treatment in both groups.The clinical efficacy and prognosis monitoring results were also compared.Results The total effective rate and the proportion of patients with a clinical dementia rating score of 0 in study group were higher than those in control group(P＜0.05).The cognitive function and daily living ability scores in study group were higher than those in control group(P＜0.05).The copy numbers of lactobacillus and bifidobacterium in study group were higher than those in control group,while the copy numbers of enterococcus and escherichia coli were lower(P＜0.05).The relative expression levels of amyloid-β protein 1-42,IL-6,TNF-α,TLR4,and NF-κB in study group were lower than those in control group,and the levels of 5-HT and GABA were higher(P＜0.05).Conclusion Probiotics can delay the progression of early AD patients and improve clinical efficacy.It is speculated that the mechanism of action may be related to regulating the brain-gut-microbiota axis-mediated LPS/TLR4/NF-κB pathway to restore the intestinal microecology and alleviate neurological inflammation.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective: Whether elevation in plasma levels of amyloid and tau protein biomarkers are better indicators of cognitive decline than higher baseline levels in patients with amnestic mild cognitive impairment (aMCI) and Alzheimer’s disease (AD) remains understudied. Methods: We included 67 participants with twice testing for AD-related plasma biomarkers via immunomagnetic reduction (IMR) assays (amyloid beta [Aβ]1-40, Aβ1-42, total tau [t-Tau], phosphorylated tau [p-Tau] 181, and alpha-synuclein [α-Syn]) and the Mini-Mental State Examination (MMSE) over a 1-year interval. We examined the correlation between biomarker levels (baseline vs. longitudinal change) and annual changes in the MMSE scores. Receiver operating characteristic curve analysis was conducted to compare the biomarkers. Results: After adjustment, faster cognitive decline was correlated with lower baseline levels of t-Tau (β=0.332, p=0.030) and p-Tau 181 (β=0.369, p=0.015) and rapid elevation of t-Tau (β=-0.330, p=0.030) and p-Tau 181 levels (β=-0.431, p=0.004). However, the levels (baseline and longitudinal changes) of Aβ1-40, Aβ1-42, and α-Syn were not correlated with cognitive decline. aMCI converters had lower baseline levels of p-Tau 181 (p=0.002) but larger annual changes (p=0.001) than aMCI non-converters. The change in p-Tau 181 levels showed better discriminatory capacity than the change in t-Tau levels in terms of identifying AD conversion in patients with aMCI, with an area under curve of 86.7% versus 72.2%. Conclusion We found changes in p-Tau 181 levels may be a suitable biomarker for identifying AD conversion.

Heart rate is a crucial indicator of human health with significant physiological importance. Traditional contact methods for measuring heart rate, such as electrocardiograph or wristbands, may not always meet the need for convenient health monitoring. Remote photoplethysmography (rPPG) provides a non-contact method for measuring heart rate and other physiological indicators by analyzing blood volume pulse signals. This approach is non-invasive, does not require direct contact, and allows for long-term healthcare monitoring. Deep learning has emerged as a powerful tool for processing complex image and video data, and has been increasingly employed to extract heart rate signals remotely. This article reviewed the latest research advancements in rPPG-based heart rate measurement using deep learning, summarized available public datasets, and explored future research directions and potential advancements in non-contact heart rate measurement.
