Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective:To investigate the application of patient-based real-time quality control (PBRTQC) using exponentially weighted moving average (EWMA) method in internal quality control (IQC) procedures of thyroid function tests.Methods:The serum thyroid function test results of outpatients and inpatients in the Second Hospital of Shandong University from December 1, 2022 to April 30, 2023 were collected. Based on the PBRTQC professional intelligent software system, normality correction, parameter setting, program preparation and real-time operation of test data were carried out. The results of all patients who underwent thyroid function testing between May 1, 2023 and August 31, 2023 were used as the validation dataset. The estimated EWMA value of thyroid function test results and the cumulative coefficient of variation ( CV) over 4 months were calculated. The cumulative CV was compared with the criteria of precision quality standard (1/3TEa) and the CV of IQC. Westgard 2-2s and 1-3s rules were used for alarm setting. The early warning information of the EWMA quality control program were recorded and the potential causes of performance changes were analyzed. DxLab Mind software was used to conduct normal distribution statistics for all data, and the Kolmogorov-Smirnov test was performed on the test results. Results:The items related to serum thyroid function of the patients were all positively skewed. After data correction by Box-Cox method, the PBRTQC data of free triiodothyronine (FT3) and free thyroxine (FT4) were normally distributed, and their cumulative precisions ( CV) of EWMA within 4 months were 6.26% and 2.86%, respectively, both of which were lower than the precision quality target of 8.33%. However, the data of thyroid-stimulating hormone (TSH), thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibody (TgAb) were still positive skewed after modification. The EWMA cumulative CV of TSH, TPOAb and TgAb were 13.16%, 15.31% and 16.77%, which were higher than the precision quality targets of 8.33%, 10% and 10%, respectively. The EWMA QC program can detect different out-of-control alarms, including FT4 false alarms due to sample source concentration and TSH result bias caused by changes in reagent performance. In addition, the EWMA QC program can also detect differences in FT3 results between different DXI800 fully automated chemiluminescence instrument instruments. Conclusions:The EWMA program based on PBRTQC professional intelligent software tools can monitor the patient data of the detection system in real time and continuously, dynamically identify and monitor the errors generated during the analysis process and give early warning. It can be used as a useful supplement for the daily IQC of thyroid function items, especially FT3 and FT4, and has good clinical application value.

Objective:To evaluate knee biomechanics of patients about 12 months after anterior cruciate ligament(ACL)reconstruction during cutting and determine the abnormal biomechanical characteristics.Methods:Sixteen males about 12 months after ACL reconstruction were recruited for this study.Three-dimensional kinematic and kinetic data were collected during cutting movement.Knee joint angles and moments were calculated.Paired t-tests were used to compare the differences in knee biomechanics be-tween the surgical leg and nonsurgical leg.Results:The peak posterior ground reaction force(surgical leg:0.380±0.071;nonsurgical leg:0.427±0.069,P=0.003)and vertical ground reaction force(surgical leg:1.996±0.202,nonsurgical leg:2.110±0.182,P=0.001)were significantly smaller in the surgical leg than in the nonsurgical leg.When compared with the uninjured leg,the surgical leg demonstrated a smaller knee flexion angle(surgical leg:38.3°±7.4°;nonsurgical leg:42.8°±7.9°,P＜0.001)and larger external rotation angle(surgical leg:10.3°±2.4°;nonsurgical leg:7.7°±2.1°,P=0.008).The surgical leg also demonstrated a smaller peak knee extension moment(surgical leg:0.092±0.031;nonsurgical leg:0.133±0.024,P＜0.001)and peak knee external rotation moment(surgical leg:0.005±0.004;nonsurgical leg:0.008±0.004,P=0.015)when com-pared with the nonsurgical leg.Conclusion:The individuals with ACL reconstruction mainly showed asymmetrical movements in the sagittal and horizontal planes.The surgical leg demonstrated a smaller peak knee flexion angle,knee extension moment,and knee external rotation moment,with greater knee external rotation angle.

Objective:To explore the causes of self-management dilemma in young and middle-aged patients with recurrent acute pancreatitis from the perspectives of nurses, patients and patient caregivers, in order to provide reference for developing self-management intervention plans that meet the needs of patients.Methods:Using the descriptive phenomenological methods from qualitative research, 15 patients with recurrent acute pancreatitis, six nurses and nine caregivers from the Hepatobiliary Pancreatic Surgery Ward of the Second Norman Bethune Hospital of Jilin University from November 2021 to December 2022 were selected for semi-structured in-depth interviews. The Colaizzi 7-step method was used to analyze and refine the theme.Results:Two main themes were extracted to explain the difficulties in self-management of young and middle-aged patients with recurrent acute pancreatitis. The internal reasons for the self-management dilemma included cognitive biases in the importance of self-management, limited access to self-management knowledge and negative attitudes towards self-behavior management, and the external reasons for self-management dilemma included insufficient inclusiveness of the external environment towards diseases, fear of disease progression, multiple burdens caused by diseases and busy work.Conclusions:Young and middle-aged patients with recurrent acute pancreatitis experience multiple difficulties in the process of self-management. Clinical medical staff should explore self-management models with contemporary characteristics, enhance patient self-management ability and quality of life, reduce disease recurrence rate.

The family readiness for discharge of premature infants in the Neonatal Intensive Care Unit (NICU) is an important index to evaluate the safe discharge of premature infants, and a good family discharge readiness is the basic guarantee for the smooth recovery and healthy growth of premature infants. This article summarizes the concept, influencing factors, and intervention strategies of family discharge readiness for premature infants in NICU, in order to provide reference for the formulation and improvement of discharge readiness measures for premature infants in NICU.

With the application of accelerated rehabilitation surgery mode in metabolic bariatric surgery, the postoperative hospital stay of patients is gradually shortened, but it also leads to the lack of postoperative knowledge of patients after discharge. Adequate guidance on discharge readiness is beneficial for improving the self-management ability of patients and improving dietary, medication and exercise compliance. This paper reviews the status quo, assessment tools, influencing factors and intervention measures of discharge readiness of patients undergoing metabolic bariatric surgery, in order to provide references and ideas for developing discharge readiness evaluation tools and related studies for patients undergoing metabolic bariatric surgery in China.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.
