Objective Based on the “excellent” performance achieved by our institution in the 2024 national intercomparison of monitoring individual dose from external exposure, this paper systematically summarizes key technical elements and optimization experiences in instrument calibration, operational protocols, and data analysis, aiming to provide methodological references and practical support for continuously enhancing the accuracy and reliability of individual dose monitoring. Methods As a participant in the intercomparison activity, our laboratory strictly followed the technical protocol formulated by the Chinese Center for Disease Control and Prevention. Results In the 2024 national intercomparison of monitoring individual dose from external exposure, the measurement results met the criteria of single-group performance \begin{document}$ \left|{P}_{i}\right| $\end{document} ≤ 0.10 and comprehensive performance B² + S² ≤ 0.10², and were rated as excellent. Conclusion The accuracy and reliability of monitoring individual dose from external exposure depend on the precision of instrument calibration, standardization of operations, and strictness of quality control. The effectiveness of the above quality control methods has been confirmed by the practice of our laboratory. These methods can be used to ensure the accuracy of measurement results.

Objective To investigate the effect of ankle pump exercises,based on hemodynamic mechanisms,on the prevention of venous thrombosis in stroke patients.Methods A total of 110 stroke patients,admitted to a tertiary A hospital in Jiangsu Province between June 2023 and June 2024,were selected using a convenience sampling method.The patients were divided into an experimental group and a control group,with 55 patients in each group.The experimental group received ankle pump exercise nursing interventions based on hemodynamic mechanisms,while the control group received routine nursing interventions.The incidence of lower extremity deep vein thrombosis,Pittsburgh Rehabilitation Participation Scale scores,subjective perceived fatigue,and exercise self-efficacy scores were compared between 2 groups on the 7th day of hospitalization.Results No dropouts occurred in either group.The incidence of deep vein thrombosis was significantly lower in the experimental group than it in the control group(P=0.004).The Pittsburgh Rehabilitation Participation scores on day 1,3,5,and 7 were higher in the experimental group compared to them in the control group(P＜0.001).A significant time-dependent trend was observed in Pittsburgh Rehabilitation Participation scores(P=0.034).Subjective fatigue was significantly lower in the experimental group at various time points(P＜0.001).Both groups showed an increase in exercise self-efficacy over time(P=0.016),with the experimental group demonstrating higher exercise self-efficacy than the control group on the day before discharge(P=0.003).Conclusion Ankle pump exercises,based on hemodynamic mechanisms,can effectively reduce the incidence of deep vein thrombosis in stroke patients,enhance rehabilitation participation and exercise self-efficacy,without increasing subjective fatigue.

Background::Despite the adverse effects of ambient fine particulate matter (PM 2.5) on type 2 diabetes and the beneficial role of physical activity (PA), the influence of PM 2.5 on the relationship between PA and type 2 diabetes remains unclear. Methods::In this prospective study with 71,689 participants, PA was assessed by a questionnaire and was categorized into quartiles for volume and three groups for intensity. Long-term PM 2.5 exposure was calculated using 1-km resolution satellite-based PM 2.5 estimates. PM 2.5 exposure and PA's effect on type 2 diabetes were assessed by cohort-stratified Cox proportional hazards models, individually and in combination. Results::In 488,166 person-years of follow-up, 5487 incident type 2 diabetes cases were observed. The association between PA and type 2 diabetes was modified by PM 2.5. Compared with the lowest quartile of PA volume, the highest quartile was associated with reduced type 2 diabetes risk in low PM 2.5 stratification (≤65.02 μg/m 3) other than in high PM 2.5 stratification (>65.02 μg/m 3), with the hazard ratio (HR) of 0.75 (95% confidence interval [CI]: 0.66-0.85) and 1.10 (95% CI: 0.99-1.22), respectively. Similar results were observed for PA intensity. High PM 2.5 exposure combined with the highest PA levels increased the risk of type 2 diabetes the most (HR= 1.79, 95% CI: 1.59-2.01 for PA volume; HR = 1.82, 95% CI: 1.64-2.02 for PA intensity). Conclusion::PA could reduce type 2 diabetes risk in low-pollution areas, but high PM 2.5 exposure may weaken or even reverse the protective effects of PA. Safety and health benefits of PA should be thoroughly assessed for long-term polluted residents.

In order to understand the characteristics of avian leukosis virus(ALV)infection and the polymorphisms of receptor genes Tva,Tvb and NHE1 sequences in different Qingyuan Ma chick-en breeding farms,the isolation and identification of exogenous ALV virus,receptor gene amplifi-cation and sequencing analysis were carried out in five Qingyuan Ma chicken breeding farms.The results of virus isolation and subtype identification showed that the positive rate of exogenous ALV virus isolation in farms A,B and C was less than 5％,among which there was ALV-J infection alone in farm A,mixed infection with ALV-J and ALV-K in farm B,ALV-K infection a-lone in farm C,and no exogenous ALV infection was detected in farm D and E.Polymorphism anal-ysis of recipient genes showed that there were different frequencies of Tvar3,Tvar4 and Tvbr3 re-sistance alleles in A-E farms,and the distribution frequency of Tvar3 was 0.2-0.6,the distribution frequency of Tvar4 was 0.3-0.7,and the distribution frequency of Tvbr3 was 0.1-0.7.In addition,there were Tvar5 resistance alleles in both B and D farms,with a distribution frequency of 0.2.A to-tal of 18 SNP mutations occurred in the NHE1 receptor gene sequence,and further analysis showed that positions 1 279,1 361,1 369,1 406,1 442,and 1 912 were non-synonymous mutations,which could cause changes in amino acids.The study suggested that there were differences in the exogenous ALV and its subtypes among the five Qingyuan Ma chicken breeders,and each farm should have a more targeted and unique purification strategy.The distribution of Tva and Tvb re-sistance alleles at different frequencies,along with the occurrence of 6 non-synonymous mutations in the NHE1 gene,indicate that Qingyuan Ma chicken have the potential of genetic resistance breeding.

Objective To investigate the correlation of human epididymis protein 4(HE4)with proteinuria in patients with type 2 diabetes mellitus(T2DM).Methods A total of 147 T2DM patients from January 2020 to July 2023 in Jiujiang NO.l People's Hospital were enrolled in observation group.According to the severity of proteinuria,observation group was divided into three groups:Normal albuminuria group(101 cases),microalbuminuria group(25 cases),and massive albuminuria group(21 cases).50 healthy examinees with gender and age matching during the same period were selected as control group.HE4 levels and clinical indicators in each group were compared and analyzed.Correlation between HE4 and proteinuria was analyzed by using univariate and multivariate linear regression.Results The correlation network diagram reveals that HE4 functions was a pivotal node linking serum albumin,urinary microalbumin,urinary microalbumin-to-creatinine ratio(UACR),and renal function biomarkers.Compared to control group,HE4 levels significantly elevated in observation group(P＜0.01).Both univariate and multivariate linear regression analysis demonstrate a positive correlation between HE4 and UACR.Logistic regression analysis shew that after adjusting for confounding factors including age,gender,estimated glomerular filtration rate(eGFR),albumin(ALB),blood urea nitrogen(BUN),serum creatinine(SCr),uric acid(UA),lactate dehydrogenase(LDH)etc.elevated HE4 levels was a risk factor for proteinuria(OR=1.110,95％CI:1.005-1.226).Conclusion Elevated HE4 levels in patients with T2DM is positivly correlated with UACR.Increase its level increases the risk of proteinuria in T2DM patients.

BACKGROUND: Congenital heart disease (CHD) is one of the most common congenital malformations in humans. Inconsistent results emerged in the existed studies on associations between air pollution and congenital heart disease. The purpose of this study was to evaluate the association of gestational exposure to air pollutants with congenital heart disease, and to explore the critical exposure windows for congenital heart disease. METHODS: The nested case-control study collected birth records and the following health data in Tianjin Women and Children's Health Center, China. All of the cases of congenital heart disease from 2013 to 2015 were selected matching five healthy controls for each case. Inverse distance weighting was used to estimate individual exposure based on daily air pollution data. Furthermore, the conditional logistic regression with distributed lag non-linear model was performed to identify the association between gestational exposure to air pollution and congenital heart disease. RESULTS: A total of 8,748 mother-infant pairs were entered into the analysis, of which 1,458 infants suffered from congenital heart disease. For each 10 µg/m³ increase of gestational exposure to PM_2.5, the ORs (95% confidence interval, 95%CI) ranged from 1.008 (1.001-1.016) to 1.013 (1.001-1.024) during the 1^st-2^nd gestation weeks. Similar weak but increased risks of congenital heart disease were associated with O₃ exposure during the 1^st week and SO₂ exposure during 6^th-7^th weeks in the first trimester, while no significant findings for other air pollutants. CONCLUSIONS This study highlighted that gestational exposure to PM_2.5, O₃, and SO₂ had lag effects on congenital heart disease. Our results support potential benefits for pregnancy women to the mitigation of air pollution exposure in the early stage, especially when a critical exposure time window of air pollutants may precede heart development.
