Objective To retrospectively analyze the prevention and control effect and epidemic characteristics of elderly tuberculosis in Hubei Province from 2016 to 2020, and to provide a scientific basis for the prevention and treatment of elderly tuberculosis in Hubei Province． Methods The data on tuberculosis patients aged 60 and above who registered their current address in Hubei Province from 2016 to 2020 were collected and analyzed. The registration rates and composition ratios were analyzed using χ² test and χ² test for trend. Results A total of 135 976 tuberculosis patients were reported in Hubei from 2016 to 2020. The annual average registration rate of elderly tuberculosis among the elderly registered residence population (referring to the registration rate of elderly registered residence population aged 60 and above as the denominator, and tuberculosis patients aged 60 and above as the numerator) was 263.51/100 000. The highest rate was 300.02/100,000 in 2017, and the lowest was 188.19/100,000 in 2020 (χ²=70,227.603, P<0.001). In terms of composition, the average annual proportion of tuberculosis patients in the 60-70 years old group was 59.60%, which decreased year by year (χ²_trend=40.448，P<0.001 ). The average annual proportion of males was 73.35%, which was significantly higher than that of females (26.65%). The average annual proportion of farmers was 62.03%. From the perspective of case management, the annual average proportion of major epidemic online reports was 85.17%. The classification of cases was mainly based on clinical diagnosis, accounting for 48.33% annually and showing a decreasing trend year by year (χ²_trend=740.911, P<0.001). The proportion of confirmed cases was 25.08%, which showed an increasing trend (χ²_trend=380.557, P<0.001). From 2016 to 2019, the delay rate of diagnosis and treatment of elder tuberculosis patients was 49.42% (67 876/135 967), and the delay rate decreased year by year (χ²_trend=323.764, P<0.001). Conclusion The elderly population with pulmonary tuberculosis in Hubei Province shows a downward trend. It is necessary to focus on the efforts of designated hospitals to proactively identify cases, increase the proportion of confirmed cases, maintain a high tracking in place, reduce medical delays, and ensure the effectiveness of tuberculosis prevention and treatment for the elderly.

Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

Objective To investigate the basic situation and occupational health conditions of nuclear medicine radiation workers in Jiangsu Province based on the research protocol developed by the Institute of Radiation Medicine, Chinese Academy of Medical Sciences for the nationwide study on the health effects of nuclear medicine radiation in China, understand the impact of occupational radiation on the physical health of nuclear medicine radiation workers, and provide a basis for improving the occupational protection of nuclear medicine radiation workers and reducing the risk of occupational radiation-related health issues. Methods A census approach was used to collect general data and occupational health information of nuclear medicine radiation workers in Jiangsu Province. The analysis focused on the abnormalities in physical examination indicators among radiation workers of different genders, ages, and working years to evaluate the health effects of occupational radiation exposure. Results The occupational health examination data of 472 nuclear medicine radiation workers were collected from 76 medical institutions in Jiangsu Province. The results showed that the detection rate of abnormal hypothyroidism in female workers (8.90%) was higher than that in male workers (2.54%) (P=0.028). With increasing working years, the detection rates of cataract and continuous decrease in white blood cell count increased (P＜0.001). The multivariate logistic regression identified working years as a risk factor for cataract and continuous decrease in white blood cell count (OR=1.59, 95%CI=1.40-3.35, P=0.0003; OR=4.15, 95%CI=3.11-29.91, P=0.0001). In addition, working years was also a risk factor for hypertension, fatty liver, and tumor (OR=2.28, 95%CI=1.51-3.47, P=8.76 × 10⁻⁵; OR=1.69, 95%CI=1.10-2.58, P=0.0145; OR=2.04, 95%CI=1.00-4.16, P=0.0469). Conclusion The study found that working in nuclear medicine could increase the risk of various radiation-related diseases, and the risk is influenced by factors such as working years.

OBJECTIVE To investigate the positive rates and distribution of multiple allergens in children aged 6 to 14 with allergic rhinitis(AR) in the Chaozhou area,and to explore whether health education plays a positive role in these patients. METHODS A random sample of 100 school-age children diagnosed with AR at the outpatient department of Chaozhou Central Hospital from January to May 2024 was selected for allergen testing. Additionally,100 school-age children diagnosed with AR at the outpatient department of Chaozhou Central Hospital from January to May 2024 were surveyed before and after intervention using the same self-made questionnaire,and the effectiveness of the intervention was evaluated. RESULTS Among school-age children with AR in Chaozhou area,the top three positive rates of allergens were house dust mites/dust mites(42％),milk(29％) and egg(23％),and the top three strong positive rates were also house dust mites/dust mites(27％),milk(18％) and egg(17％). After health education,the correct response rate to questions on how to reduce AR attacks increased compared to before the intervention. The overall awareness of AR health knowledge was 31.7％,which significantly increased to 91.4％ after the intervention,with a statistically significant difference. CONCLUSION Understanding the positive rates and distribution of allergens in the Chaozhou area is very important for diagnosing and managing allergic symptoms,which can help physicians and patients better cope with AR. Health education can significantly improve school-age children's understanding of AR,promote the formation of good hygiene habits and lifestyles,and has a positive impact on the prevention and treatment of AR in school-age children.

Objective:To investigate the predictive value of clinical factor model, deep learning model based on baseline plain CT images, and combination of both for predicting hematoma expansion in cerebral hemorrhage.Methods:The study was cross-sectional. Totally 471 cerebral hemorrhage patients who were firstly diagnosed in the Second Affiliated Hospital of Soochow University from January 2017 to December 2021 were collected retrospectively. These patients were randomly divided into a training dataset ( n=330) and a validation dataset ( n=141) at a ratio of 7∶3 by using the random function. All patients underwent two noncontrast CT examinations within 24 h and an increase in hematoma volume of >33% or an absolute increase in hematoma volume of >6 ml was considered hematoma enlargement. According to the presence or absence of hematoma enlargement, all patients were divided into hematoma enlargement group and hematoma non-enlargement group.Two-sample t test, Mann-Whitney U test or χ2 test were used for univariate analysis. The factors with statistically significant differences were included in multivariate logistic regression analysis, and independent influences related to hematoma enlargement were screened out to establish a clinical factor model. ITK-SNAP software was applied to manually label and segment the cerebral hemorrhage lesions on plain CT images to train and build a deep learning model based on ResNet50 architecture. A combination model for predicting hematoma expansion in cerebral hemorrhage was established by combining independent clinical influences with deep learning scores. The value of the clinical factor model, the deep learning model, and the combination model for predicting hematoma expansion in cerebral hemorrhage was evaluated using receiver operating characteristic (ROC) curves and decision curves in the training and validation datasets. Results:Among 471 cerebral hemorrhage patients, 136 cases were in the hematoma enlargement group and 335 cases were in the hematoma non-enlargement group. Regression analyses showed that male ( OR=1.790, 95% CI 1.136-2.819, P=0.012), time of occurrence ( OR=0.812, 95% CI 0.702-0.939, P=0.005), history of oral anticoagulants ( OR=2.157, 95% CI 1.100-4.229, P=0.025), admission Glasgow Coma Scale score ( OR=0.866, 95% CI 0.807-0.929, P<0.001) and red blood cell distribution width ( OR=1.045, 95% CI 1.010-1.081, P=0.011) were the independent factors for predicting hematoma expansion in cerebral hemorrhage. ROC curve analysis showed that in the training dataset, the area under the curve (AUC) of clinical factor model, deep learning model and combination model were 0.688 (95% CI 0.635-0.738), 0.695 (95% CI 0.642-0.744) and 0.747 (95% CI 0.697-0.793) respectively. The AUC of the combination model was better than that of the clinical model ( Z=0.54, P=0.011) and the deep learning model ( Z=2.44, P=0.015). In the validation dataset, the AUC of clinical factor model, deep learning model and combination model were 0.687 (95% CI 0.604-0.763), 0.683 (95% CI 0.599-0.759) and 0.736 (95% CI 0.655-0.806) respectively, with no statistical significance. Decision curves showed that the combination model had the highest net benefit rate and strong clinical practicability. Conclusions:Both the deep learning model and the clinical factor model established in this study have some predictive value for hematoma expansion in cerebral hemorrhage; the combination model established by the two together has the highest predictive value and can be applied to predict hematoma expansion.

Objective:To investigate the effects of long-term X-ray radiation exposure on the tumor risk of medical X-ray workers in Jiangsu province, and to provide a scientific basis for the development of occupational protection policies and the improvement of workers′ health.Methods:By using a combination of retrospective and prospective cohort research method, the medical diagnostic X-ray workers who worked in the radiology department of all hospitals in Jiangsu province between 1950 and 1980 were selected as the radiology group.In the meantime medical personnel in internal medicine, otorhinolaryngology, pediatrics and other medical departments who had not been engaged in radiology during the same period of time at the same hospital were selected as the control group to form a survey cohort. The cumulative number of person-years of observation of the cohort during 1950-2011 was calculated, and the relative risk of various malignant tumors among medical X-ray workers was calculated by using Cox regression model after adjusting for sex, attained age, year of birth, and year of work initiation.Results:A total of 6 954 follow-ups was completed for the cohort, including 3 649 in the irradiation group and 3 305 in the control group, totally 340 483 person-years of observation. As of December 31, 2021, there were 1 328 patients with malignant tumors in this cohort. Cox regression result showed that compared with the control group, the irradiation group who had developed lung cancer ( RR=1.60, 95% CI 1.24-2.08), lymphoma ( RR =4.28, 95% CI 1.54-11.93), solid cancer ( RR =1.17, 95% CI 1.04-1.31), and total cancer ( RR =1.29, 95% CI 1.14-1.46) had significantly higher relative risks ( Z=3.56, 2.78, 2.71, 3.96, P<0.05). Stratified analyses showed that the risks of lung, lymphoma, solid and total cancers were higher in the radiation group than in the control group for males and for those who arrived at the age of 61 years or older ( χ2=6.70-33.86, P<0.05). The risks of lung, solid and total cancers were higher in the radiation group than in the control group for those who started to work in the age group of 21 to 25 years ( χ2=6.46, 6.16, 5.62, P<0.05). Conclusions:The relative risks of lung, lymphoma, solid and total cancers among medical X-ray workers in Jiangsu province are significantly higher, suggesting that attention should be paid to strengthening radiation protection for radiation workers in their radiological practices.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

Objective To evaluate the long-term efficacy of tumor necrosis factor-α(TNF-α)inhibitor(TNFi)in the treatment of ankylosing spondylitis(AS)complicated with osteoporosis(OP)and the impact on bone metabolism,bone density,and inflammatory factors.Methods The data of 158 patients with AS and OP,who were admitted to Department of Rheumatology and Immunology of The First Affiliated Hospital of Naval Medical University(Second Military Medical University)from Jan.1,2010 to Dec.31,2017,were retrospectively collected.The patients were divided into bisphosphonate group(n=54),TNFi group(n=58),and TNFi+bisphosphonate group(n=46)according to the treatment methods.All patients were treated with calcium combined with calcitriol as the background treatment.After 5 years of treatment,Bath ankylosing spondylitis disease activity index(BASDAI)and Bath ankylosing spondylitis functional index(BASFI)scores were evaluated,and inflammatory indexes,bone metabolism markers,and bone mineral density were detected.Results After 5 years of treatment,the BASDAI and BASFI scores,erythrocyte sedimentation rate(ESR),C reactive protein(CRP),TNF-α,and interleukin-17A of the TNFi+bisphosphonate group and TNFi group were significantly lower than those before treatment(all P＜0.05);in the bisphosphonate group only ESR and CRP were significantly lower than those before treatment(both P＜0.05),and the other inflammatory indexes and BASDAI and BASFI scores showed no significant changes(all P＞0.05).The bone mineral density of the 3 groups after 5 years of treatment was significantly higher than that before treatment(all P＜0.05),and the bone mineral density of the TNFi+bisphosphonate group was significantly higher than that of the other 2 groups(both P＜0.05).After 5 years of treatment,the levels of parathyroid hormone(PTH),procollagen type 1 N-terminal propeptide(P1NP)and β-C-terminal telopeptide of type Ⅰ collagen(β-CTX)in the TNFi+bisphosphonate group and bisphosphonate group were significantly decreased compared with those before treatment(all P＜0.05),while the levels of N-terminal midfragment of osteocalcin(N-MID)and 25-hydroxy-vitamin D(25VitD)were significantly increased(all P＜0.05);in the TNFi group only PTH and P1NP levels were significantly decreased(both P＜0.05),while β-CTX,N-MID and 25VitD levels showed no significant differences(all P＞0.05).Conclusion Long-term use of TNFi in patients with AS and OP can effectively reduce disease activity,improve physical function,decrease the level of inflammatory factors,alleviate abnormal bone metabolism,and increase bone mineral density;and the combined use of TNFi and bisphosphonates has better efficacy.
