Objective To analyze the trends in the disease burden of pertussis in China from 1990 to 2021, and to provide a basis for the development of effective prevention and control strategies. Methods Using the 2021 Global Burden of Disease Study (GBD) database, the incidence, mortality, and disability-adjusted life years (DALYs), as well as the age-standardized rates of pertussis in China from 1990 to 2021 were analyzed. Descriptive statistical methods were employed to analyze the characteristics of the pertussis disease burden, and the Joinpoint regression model was used to analyze the trends in pertussis disease burden. Results From 1990 to 2021, the incidence, mortality, and DALYs of pertussis in China decreased from 1 503 800 cases, 10 951 deaths, and 954 900 person-years to 65 400 cases, 548 deaths, and 46 500 person-years, representing a decrease of 95.65%, 95.00%, and 95.13%, respectively. The corresponding age-standardized rates also decreased by 93.58%, 92.47%, and 92.53%, respectively. The Joinpoint regression model revealed a significant downward trend in the age-standardized incidence, mortality, and DALYs rates for pertussis (AAPCs were -8.32%, -9.65%, and -9.58%, respectively, P<0.001). The disease burden was slightly higher in females than in males, with the majority of cases occurring in children under 10 years old, particularly in infants under 1 year old, where the burden was the heaviest. As age increased, the disease burden decreased. Conclusion Between 1990 and 2021, the overall disease burden of pertussis in China showed a significant downward trend, with gender and age differences. Special attention should be given on the prevention and control of pertussis in children under 10 years old, especially in infants under 1 year old.

ObjectiveGlutathione (γ-glutamyl-L-cysteinylglycine, GSH) is the most abundant non-protein compound containing sulfhydryl (―SH) groups in cells. It serves as a source of reducing equivalents, effectively neutralizing harmful reactive substances, and playing a crucial role in maintaining cellular redox balance. Therefore, sensitive detection and accurate measurement of GSH levels in tissues are of great importance. In this work, we presents a novel method for GSH detection utilizing electron paramagnetic resonance (EPR) spectroscopy. MethodsInitially, ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate acid)) solution was mixed with K2S2O8 solution and reacted in the dark for 12 to 16 h to prepare ABTS·+ solution, which was then quantified using UV-Vis spectroscopy. Subsequently, the concentration of glutathione (GSH) was determined based on the changes in the EPR signal of ABTS·+. On this basis, the optimal reaction time and temperature were explored to establish a standard equation correlating the EPR signal intensity of ABTS·+ with GSH concentration. Finally, the derived standard curve was employed to quantitatively analyze the GSH concentration in whole blood from C57BL/6J mice, and the results were compared with those reported in the literature to verify the accuracy of the method. ResultsThe experimental results demonstrate that this method has a linear detection range from50 nmol/L to 15 μmol/L for GSH, spanning two orders of magnitude, with a limit of detection (LOD) at0.50 nmol/L. The measured GSH content in mouse whole blood is (10 660±706) nmol/g Hb, which agrees with the value of (11 200±237) nmol/g Hb as previously reported. Furthermore, a similar method was developed for detection of glutathione disulfide (GSSG) at higher reaction temperature. ConclusionThis article presents a novel assay for the rapid detection of GSH using the intensity of EPR signal from ABTS·+ as indicator. This method demonstrates enhanced detection sensitivity and a broader linear range compared to conventional colorimetric methods. Furthermore, we have extended the application of this method to detect GSH content in blood samples efficiently and accurately, offering valuable information for assessing tissue redox balance, thus holding significant potentials.

Objective: To describe the relapse status of smokers aged ≥15 years in China, and investigate the main factors influencing their relapse behavior. Methods: The data of this study cames from the 2018 China Adult Tobacco Survey, covering 400 committees or villages in 200 districts or counties in 31 provinces (autonomous regions and municipalities) of China. The relevant data of smoking and relapsing in residents aged ≥15 years were collected by face-to-face interview. Software SAS 9.4 was used to clean and analyze the data, and logistic regression model was used to analyze the influencing factors for relapse rate. Results: A total of 19 376 questionnaires were completed, with a response rate of 91.50%. In 2018, 66.05% of smokers aged ≥15 years in China had smoking relapse, in whom 66.59% were males and 55.79% were females. In all age groups, the age group 15-24 years had the highest smoking relapse rate (82.63%). Multivariate analysis showed that the younger age 15-24 years (OR=4.618,95%CI:1.981-10.763), e-cigarette use (OR=9.782,95%CI:3.139-30.490), and tobacco advertising, promotion and sponsorship in the past 30 days (OR=1.710,95%CI:1.291-2.265) were associated with higher smoking relapse rate. Compared with people who were allowed smoking at home or those without smoking limit, the smoking relapse rate in people who were not allowed to smoke at home (OR=0.562, 95%CI: 0.439-0.719) or those with smoking limit (OR=0.487, 95%CI: 0.366-0.647) was lower. Conclusion: The smoking relapse rate in Chinese smokers is high, especially in young people. It is suggested to conduct targeted intervention based on the results of this study to reduce the smoking relapse rate and help achieve the smoking control goal in Healthy China 2030.

ARIDI A encodes a non-catalytic subunit of SWI/SNF chromosome remodeling complex BAF. Cancer genome sequencing data based on next-generation sequencing techniques have shown that ARIDIA is frequently mutated in a variety of cancers, up to 20% in some cancer types. A growing body of evidence shows that ARIDIA, as a tumor suppressor gene, affects the occurrence and development of cancers. ARIDIA plays an important role in cell cycle, DNA replication, DNA repair and transcriptional regulation, which might contribute to tumor formation, proliferation and migration. This review article mainly describes the research progress on ARIDIA in pan-cancer, as well as potential therapeutics, hoping to provide new ideas for the diagnosis and treatment of tumors.

Individual differences of P300 potentials lead to that a large amount of training data must be collected to construct pattern recognition models in P300-based brain-computer interface system, which may cause subjects' fatigue and degrade the system performance. TrAdaBoost is a method that transfers the knowledge from source area to target area, which improves learning effect in the target area. Our research purposed a TrAdaBoost-based linear discriminant analysis and a TrAdaBoost-based support vector machine to recognize the P300 potentials across multiple subjects. This method first trains two kinds of classifiers separately by using the data deriving from a small amount of data from same subject and a large amount of data from different subjects. Then it combines all the classifiers with different weights. Compared with traditional training methods that use only a small amount of data from same subject or mixed different subjects' data to directly train, our algorithm improved the accuracies by 19.56% and 22.25% respectively, and improved the information transfer rate of 14.69 bits/min and 15.76 bits/min respectively. The results indicate that the TrAdaBoost-based method has the potential to enhance the generalization ability of brain-computer interface on the individual differences.

Objective:
To investigate the influence of five-in-one management mode(standardized asthma treatment, asthma diary, peak expiratory flow (PEF) monitoring, reasonable diet and physical exercise) on disease prevention and control of school children with asthma.
Methods:
From April to October 2018, 70 children with asthma in clinical remission were selected from Affiliated Hospital of Qingdao University using randomized controlled study design. These children were randomly divided into study group and control group, with 35 cases in each group. In the study group, 5 cases were lost to follow-up, and 30 cases were actually enrolled. In the control group, 6 cases were lost to follow-up, and 29 cases were actually enrolled. Children in the control group received routine medication and regular outpatient consultation, and children in the study group received the five-in-one asthma management model. In the first time of seeing a doctor, after 3 months and 6 months of follow-up, asthma control test score, medication compliance index score and lung function index (forced expiratory volume in 1 second (FEV1), PEF were evaluated respectively.Parental satisfaction, asthma acute episodes, weight, height and biochemical index were recorded during the 6 months of follow-up. Pulmonary function index, asthma control score and body mass index of overweight children with asthma were compared with

OBJECTIVE:
To explore the causes and specific conditions of blood donation reaction under the collective emergency unpaid blood donation, and to provide theoretical basis and decision-making reference for drafting the collective emergency unpaid blood donation and blood donation safety.
METHODS:
Through a combination of prospective and retrospective models, and statistical methods were used to analyze the causes and conditions of the blood donation response of 10401 people participating in collective emergency unpaid blood donation during 2016.1-2018.8.
RESULTS:
A total of 10401 person-times donated blood in a sitting manner, and a total of 293 blood donation reactions occurred. By improving the blood donation services year by year, the moderate blood donation reaction during the year 2017 and 2018 was significantly lower than that in 2016 (P<0.05). In the actual blood donation group of≤100, 200, 300 and 400 ml, the incidence of blood donation reaction was statistically significant (P<0.05); the incidence of blood donation reaction in the blood donors for 1,2,3 and >3 drnations was also statistically significant (P<0.05); the blood donation reactions rate of B antigen containers was significantly different from the donors without B antigen (P<0.05); the incidence of blood donation reaction with related to the weight of the donor.
CONCLUSION
The blood donation reaction of collective emergency unpaid blood donation closely relates with mental factors, blood donation service, blood donation frequency and body weight of the blood donor. The first blood donation is more likely to produce blood donation reaction. The blood donation volum≤ 100 ml from blood donors is resulted mostly from blood donation reactions.
