Objective: To investigate the precise detection methods for weak partial D type 15 and evaluate their implications for blood transfusion safety, along with the development of corresponding strategies. Methods: A combination of serological methods, including the microplate method, indirect antiglobulin tube method, and microcolumn gel card method, was employed to identify RhD-negative and RhD variant samples. RhD-negative samples were screened for the presence of RHD genes using whole-blood direct PCR amplification. Subsequently, RhD variant samples and RhD-negative samples containing RHD genes underwent full-coding-region sequencing of the RHD gene to confirm their genotypes. The genotyping results were further correlated with the serological test findings for comprehensive analysis. Results: Among 615 549 first-time healthy blood donors, 3 401 samples with an RhD-negative phenotype and 156 samples with RhD variant were identified. Of the 3 401 RhD-negative samples, 1 054 were found to harbor RHD genes. Gene sequencing analysis of the 156 RhD variants and the 1 054 serological negative samples revealed that 89 samples contained the RHD 15 (c. 845G>A) allele. Conclusion: The integration of serological testing methods and genotyping technologies for the precise determination of RhD blood type plays a critical role in ensuring the safety and compatibility of blood transfusions.

Objective: To investigate the association between plant-based diet and different types of obesity, so as to provide references for obesity prevention. Methods: Residents aged 35-75 years from 33 counties (cities, districts) in Zhejiang Province were selected as study subjects using a multistage stratified random sampling method between April and December 2024. Demographic information and living behaviors were collected using questionnaire surveys. Height, weight and waist circumference were measured, and body mass index (BMI) was calculated. BMI ≥28.0 kg/m2 was defined as obesity, waist circumference ≥90 cm in males or ≥85 cm in females was defined as central obesity, and individual with obesity who also had central obesity was defined as having compound obesity. Food intake over a 3-day period was collected using the consecutive 3-day 24-hour dietary recall method. The plant diet index (PDI), healthful plant diet index (HPDI), and unhealthful plant diet index (UPDI) were calculated, and categorized into quintiles (Q1-Q5) based on their distribution. Association between the PDI, PDI, UPDI and different types of obesity were analyzed using multivariable logistic regression models. Results: A total of 4 882 individuals were surveyed, including 2 233 males (45.74%) and 2 649 females (54.26%). The average age was (55.42±12.14) years. There were 537 individuals of obesity, 1 718 individuals of central obesity, and 500 individuals of compound obesity, with detection rates of 11.00%, 35.19%, and 10.24%, respectively. Multivariable logistic regression analysis showed that, after adjusting for demographic information and living behaviors, compared with Q1 group, HPDI Q5 group showed a 29.6% lower risk of obesity (OR=0.704, 95%CI: 0.525-0.943) and a 32.1% lower risk of compound obesity (OR=0.679, 95%CI: 0.502-0.918). Conversely, the UPDI Q5 group exhibited a 39.5% higher risk of obesity (OR=1.395, 95%CI: 1.032-1.886) and a 39.8% higher risk of compound obesity (OR=1.398, 95%CI: 1.025-1.907). No statistically significant association was found between PDI and obesity, central obesity, and compound obesity (all P>0.05). As HPDI increased, the risks of obesity and compound obesity showed decreasing trends; as UPDI increased, the risks of obesity and compound obesity showed increasing trends (all Ptrend<0.05). Conclusion A healthful plant-based diet is associated with reduced risks of obesity and compound obesity, while an unhealthful plant-based diet is associated with increased risks of obesity and compound obesity.

Background China is a major coal producer and consumer country in the world. Coal workers' pneumoconiosis (CWP) is a primary factor endangering the occupational health of coal miners. Research on the disease burden of CWP and its changing trend is significant for disease prevention & control and associated policies. Objective To analyze the disease burden of CWP in China from 1990 to 2021 and its changing trend, and predict the disease burden from 2022 to 2035. Methods Using the Global Burden of Disease Study (GBD) database of 2021, numbers ofincident cases, prevalent cases, deaths, and disability-adjusted life years (DALYs) as well as crude and age-standardized rates of CWP in China were retrieved. Linear regression model was used to calculate the estimated annual percentage change (EAPC) of the age-standardized rates. Joinpoint regression model was used to analyze the temporal trend of disease burden and the disease burden of different sexes and age groups, and Bayesian age-period-cohort (BAPC) model was used to forecast the trend of CWP disease burden. Results In 1990, the incident, prevalent, and deaths cases of CWP in China were 3266, 18872, and 1561, respectively, and the DALYs of CWP were 44614.718 person-years. In 2021, the incident, prevalent, and deaths cases of CWP were 3446, 23975, and 1229, respectively, and the DALYs of CWP were 29610.754 person-years. From 1990 to 2021, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP in China all showed a downward trend, with the EAPCs of −3.121%, −2.532%, −4.018%, and −4.268%, respectively. The disease burden of CWP in China was mainly concentrated in the male population. The annual average percent change analysis indicated that each standardized rate showed a fluctuating downward trend in different periods. The BAPC model showed that from 2022 to 2035, the age-standardized rates of CWP in China would continue to decline steadily. In 2035, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP would be reduced to 0.10 per 100000, 0.74 per 100000, 0.03 per 100000, and 0.74 per 100000, respectively. Conclusion The disease burden contributed by CWP in China generally show a downward trend from 1990 to 2021, and it is expected that the age-standardized rates will continue to decline steadily from 2022 to 2035.

To further investigate the molecular genetic characteristics of enzomatic nasal tumor vi-rus of goats(ENTV-2)in Yunnan Province,this study measured and analyzed the entire genome of ENTV-2 in Yunnan Province.The results showed that the complete genome sequence of the EN-TV-2 YN2023 strain(GenBank accession number:PP682590.1)was successfully obtained.The YN2023 strain has a total length of 7 307 bp and a typical structure of 5'-M5-gag-pro-pol-env-M3-3'.Whole genome sequence homology analysis showed that the nucleotide homology between YN2023 strain and 41 reference strains ranges from 85.3％to 95.5％.The whole genome evolution-ary tree indicates that the YN2023 strain is closely related to the prevalent strains in China,with certain genetic diversity and geographical clustering.The analysis of the gag gene evolutionary tree shows that the gag gene cluster of YN2023 strain is on a branch of the ENTV-2 gag gene,and YN2023 is clustered on the same small branch as enENTV-FJ1 and GDQY2017 strains,with the closest genetic relationship.The env gene evolutionary tree shows that YN2023 is on the same branch as GDQY2017,GDZJ2022,ENTV-2CHN1-6,ENTV-FJ1,and ENTV-FJ3,and is also on the same branch as GDQY2017,indicating a close genetic relationship.Recombination analysis showed that the YN2023 strain underwent a potential recombination event between breakpoint positions 6378-7478 bp,with the Chinese Chongqing strain enENTV-CQ1(OR669623.1)as the primary parent and the Chinese Sichuan strain BH(MT254062.1)as the secondary parent.This study enriches the genomic information of the ENTV-2 strain in Yunnan Province and provides data sup-port for the genetic variation of ENTV-2 in Yunnan Province.

Objective To investigate the clinical value of baseline 18F-fluorodeoxyglucose(18F-FDG)PET/CT metabolic parame-ters and certain clinical indicators in predicting the prognosis of patients with diffuse large B-cell lymphoma(DLBCL).Methods A retrospec-tive analysis was conducted on the baseline 18 F-FDG PET/CT data of 73 DLBCL patients who received R-CHOP treatment.Patients were divided into progression group(24 cases)and non-progression group(49 cases)based on disease progression within 2 years post-treatment.The lesion maximum standardized uptake value(SUVmax),tumour-to-liver blood pool SUVmax ratio(LLR)and tumour-to-mediastinal blood pool SUVmax ratio(L-BPR)were analyzed using receiver operating characteristic(ROC)curves.Kaplan-Meier(K-M)survival curves analysis were performed based on the optimal thresholds of SUVmax,LLR and L-BPR.x2 tests were used to analyze and compare the relationship between each parameter and disease progression.Indicators that were significant in the x2 tests were included in the multivariate Cox regression analysis.Results The area under the curve(AUC)for LLR,L-BPR,and SUVmax were 0.920,0.914,and 0.848,respectively,with optimal thresholds of 7.41,10.67,and 14.70.Based on these thresholds,K-M survival curves analysis showed that the 2-year progression-free survival(PFS)rates for DLBCL patients were 79.2％vs 30.8％(P＜0.001),74.3％vs 22.0％(P=0.009),and 79.5％vs 51.6％(P=0.002),respectively.Significant differences were observed between the progression and non-progression groups in terms of LLR,L-BPR,SUVmax,extranodal involvement,international prognostic index(IPI)score,lactate dehydrogenase(LDH)level,Eastern Cooperative Oncology Group(ECOG)score,and β2-microglobulin(β2-MG)levels(P＜0.05).Multivariate Cox regression analysis revealed that the IPI score and LLR were independent predictors affecting the 2-year PFS of DLBCL patients(P＜0.05).Conclusion Baseline 18F-FDG PET/CT metabolic parameter LLR and IPI score are inde-pendent factors for predicting the prognosis of DLBCL patients.

Objective To explore the clinical effect of stereotactic body radiotherapy(SBRT)combined with dendritic cell-cytokine-induced killer cell(DC-CIK)immunotherapy in the treatment of centrally-located locally advanced non-small cell lung cancer(LA-NSCLC).Methods A total of 113 patients with centrally-located LA-NSCLC admitted from January 2022 to March 2024 were divided into the observation group(n=56)and the control group(n=57)by using the random number table method.The observation group was treated with SBRT combined with DC-CIK immunotherapy,while the control group was treated with SBRT.The clinical efficacy of the two groups after treatment,as well as the levels of tumor markers,immune function indicators and inflammatory indicators before and after treatment,was compared.The adverse reactions during the treatment period and the short-term survival during the 12-month follow-up of the two groups were recorded.Results Compared with the control group,both objective response rate and disease control rate of the observation group were higher(P<0.05).After treatment,the levels of serum carcinoembryonic antigen,cytokeratin 19 fragment and cancer antigen 125 in both groups were lower than those before treatment,and lower in the observation group than in the control group(P<0.05,P<0.01).After treatment,the levels of CD3+,CD4+,and CD4+/CD8+in the control group were lower than those before treatment,while the level of CD8+was higher than that before treatment(P<0.05).After treatment,the levels of CD3+,CD4+and CD4+/CD8+in the observation group were higher than those before treatment and also higher than those in the control group,while the level of CD8+was lower than that before treatment and also lower than that in the control group(P<0.05,P<0.01).After treatment,the interferon-γ level in the observation group was higher than that before treatment and also higher than that in the control group,while the levels of tumor necrosis factor-α and interleukin-6 were lower than those before treatment and also lower than those in the control group(P<0.05,P<0.01).There was no significant difference in the incidence of adverse reactions between the two groups during the treatment period(P>0.05).The overall survival rate of the observation group at 12-month follow-up was higher,and the median survival time was longer,as compared with the control group(P<0.05).Conclusion SBRT combined with DC-CIK immunotherapy has a definite effect in the treatment of patients with centrally-located LA-NSCLC.It can significantly improve the immune function of patients,reduce the levels of tumor markers,alleviate inflammatory responses,increase short-term survival rates,prolong survival time,and does not significantly increase adverse reactions,offering good safety and reliability.

Objective To analyze the 18F-fluorodeoxyglucose(18F-FDG)PET/CT manifestations of autoimmune pancreatitis(AIP)and to explore the diagnostic value of 18F-FDG PET/CT in AIP.Methods Twenty-three patients with suspected AIP who underwent 18F-FDG PET/CT were retrospectively analyzed.Eleven patients were diagnosed with AIP based on the International Consensus Diagnostic Criteria(ICDC)of AIP published by the International Pancreatic Disease Association.The detection rate and diagnostic sensitivity of 18F-FDG PET/CT for pancreatic enlargement,duct stenosis,duct dilation,pseudocapsules,and extrapancreatic involvement were analyzed,along with the 18F-FDG PET/CT manifestations of AIP.Results The 18F-FDG PET/CT manifestations of 11 patients with AIP:9 patients(81.82%)showed diffuse pancreatic enlargement,and 2 patients(18.18%)had local pancreatic head enlargement.And metabolism showed diffuse or localized increase.The maximum standardized uptake value(SUVmax)for the early PET/CT was 1.7-9.1(4.52±1.92),and for the delayed PET/CT,it was 2.6-9.8(5.25±1.98),with a statistically signifi-cant difference between the two phases SUVmax(t=-7.627,P<0.001).Two patients showed duct stenosis,six had distal duct dilation,and three exhibited pseudocapsule formation.Extrapancreatic involvement occurred in ten patients(90.91%),including sclerosing cholangitis,bile duct dilation inside and outside the liver,gallbladder changes,lymph node involvement,salivary gland involvement,prostate involvement,retroperitoneal fibrosis,pulmonary lesions,arteritis,and granulomatous tissue formation,etc.Among them,the same patient may present with multiple manifestations of extrapancreatic involvement.Among the 11 patients,eight were diagnosed as AIP,two as pancreatic cancer,and one as acute pancreatitis by 18F-FDG PET/CT.The diagnostic sensitivity was 72.73%.Conclusion The 18F-FDG PET/CT of AIP demonstrates specificity in anatomical morphology and metabolic changes and can better display extrapancreatic involvement,which has unique clinical value in AIP imaging diagnosis.

Objective To evaluate the diagnostic value of positron emission tomography(PET)/computed tomography(CT)and bone marrow biopsy(BMB)for bone marrow infiltration in common non-Hodgkin lymphoma(NHL).Methods We retrospectively analyzed data from 197 patients with NHL and compared the diagnostic value of PET/CT and BMB for bone marrow infiltration.Differences in PET/CT parameters and serological test results were compared between PET/CT-positive and PET/CT-negative patients as well as between BMB-positive and BMB-negative patients.Results In patients with diffuse large B-cell lymphoma(DLBCL),the sensitivities of PET/CT and BMB for detecting bone marrow infiltration were 90.5%and 66.7%,and the specificities were 95.1%and 100.0%,respectively.In patients with follicular lymphoma(FL),the sensitivities were 63.6%and 81.8%,and the specificities were 98.1%and 100.0%,respec-tively.In patients with T-cell lymphoma(TCL),the sensitivities were 60.0%and 80.0%,and the specificities were 88.0%and 100.0%,respectively.Among patients with DLBCL and TCL,significant differences were observed in platelet count and lactate dehydrogenase levels between PET/CT-positive and PET/CT-negative patients(P<0.05).Conclusion PET/CT showed excellent diagnostic perfor-mance for evaluating bone marrow infiltration in DLBCL.PET/CT had limited sensitivity for FL and TCL and might serve as a supplemen-tary tool for BMB.Platelet count and lactate dehydrogenase levels may aid in the diagnosis of bone marrow infiltration in DLBCL and TCL.
