Objective To understand the basic information of the number, classification, and distribution of radiation work units in non-medical institutions in Shanxi Province, China, and to analyze the status quo of health management and radiation protection measures for radiation workers, so as to provide a scientific basis for occupational exposure protection in non-medical radiation work units and better protect the occupational health rights and interests of radiation workers. Methods A questionnaire survey was conducted to investigate some non-medical institutions in Shanxi Province. On-site testing was carried out to determine the risk factors for radioactive occupational diseases in the selected non-medical institutions. Results In 220 non-medical institutions, there were 340 radiation devices and 2284 radioactive sources. The rate of individual dose monitoring was 92.7% and the rate of occupational health examination was 87.2%. These devices were equipped with 325 detection instruments for radiation protection, 1316 personal protective equipment, and 730 personal dose alarms. Radiation occupational disease risk factors were investigated in 101 institutions. Conclusion The occupational health management of radiation workers in non-medical institutions in Shanxi Province is generally in line with the national standards. However, there is still a big gap with the level of occupational health management in medical institutions. The health administration departments should clarify the management measures for non-medical institutions and strengthen their supervision and management functions.

OBJECTIVES:
The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States.
METHODS:
The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures.
RESULTS:
For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001).
CONCLUSIONS
From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.

Antiviral therapy can reduce the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. As for the first-line antiviral drugs, more studies have shown that tenofovir disoproxil fumarate may be better than entecavir in reducing the risk of HCC, especially among Asian patients; a limited number of studies have shown that tenofovir alafenamide fumarate may be better than tenofovir disoproxil fumarate in reducing the risk of HCC; interferon has a better effect than nucleos(t)ide analogues alone in reducing the risk of HCC. Among the currently available drugs, interferon combined with nucleos(t)ide analogues may be the best choice to reduce the risk of HCC in patients at a high risk of HCC. The level of evidence-based medicine is weak for comparing the effect of different drugs in reducing the risk of HCC, and randomized controlled trials are needed for further clarification. In practice, it is necessary to weigh the risk of HCC, drug tolerance and economic affordability based on the patient's basic conditions and actual situations, so as to develop individualized anti-viral strategies.

To study the molecular mechanism of salt stress response of peanut small GTP binding protein gene AhRabG3f, a 1 914 bp promoter fragment upstream of the start codon of AhRabG3f gene (3f-P) from peanut was cloned. Subsequently, five truncated fragments (3f-P1-3f-P5) with lengths of 1 729, 1 379, 666, 510 and 179 bp were obtained through deletion at the 5' end, respectively. Plant expression vectors where these six promoter fragments were fused with the gus gene were constructed and transformed into tobacco by Agrobacterium-mediated method, respectively. GUS expression in transgenic tobacco and activity analysis were conducted. The gus gene expression can be detected in the transgenic tobacco harboring each promoter segment, among which the driving activity of the full-length promoter 3f-P was the weakest, while the driving activity of the promoter segment 3f-P3 was the strongest. Upon exposure of the transgenic tobacco to salt stress, the GUS activity driven by 3f-P, 3f-P1, 3f-P2 and 3f-P3 was 3.3, 1.2, 1.9 and 1.2 times compared to that of the transgenic plants without salt treatment. This suggests that the AhRabG3f promoter was salt-inducible and there might be positive regulatory elements between 3f-P and 3f-P3 in response to salt stress. The results of GUS activity driven by promoter fragments after salt treatment showed that elements included MYB and GT1 between 1 930 bp and 1 745 bp. Moreover, a TC-rich repeat between 682 bp and 526 bp might be positive cis-elements responsible for salt stress, and an MYC element between 1 395 bp and 682 bp might be a negative cis-element responsible for salt stress. This study may facilitate using the induced promoter to regulate the salt resistance of peanut.

Objective:Analyze the drug resistance of Mycobacterium tuberculosis (MTB) to commonly used anti-tuberculosis drugs and its spatial distribution in Dali Bai Autonomous Prefecture from 2017 to 2019, which would provid a reference for the treatment of tuberculosis and the prevention and control of drug-resistant tuberculosis. Methods:A total of 1 013 Mycobacterial strains were isolated from sputum samples in the tuberculosis laboratories of the designated People′s hospital of 12 counties (cities) of Dali Bai Autonomous Prefecture from January 2017 to December 2019. Proportional method was used to conduct drug susceptibility tests and strain identification of 6 anti-tuberculosis drugs. Further used ArcMap10.2 and GeoDa1.14 software to visualize the map display and spatial autocorrelation analysis of the drug resistance of MTB.Results:From 2017 to 2019, the drug resistance rates of MTB in Dali Prefecture were 10.33%(28/271), 10.35%(55/531) and 30.00%(51/170), respectively, showing an rising trend ( χ2=26.62, P<0.05). Among 1 030 samples, 972 strains (95.95%) was MTB and 41 strains (4.05%) was non-tuberculous Mycobacterium (NTM). The total resistance rate of 972 strains of MTB was 13.79% (134/972), of which the single resistance rate was 6.59% (64/972), the multi-drug resistance rate was 4.84% (47/972), and the poly-drug resistance rate was 2.06% (20/972), the rate of extensive drug resistance is 0.31% (3/972). There are 25 combinations of drug resistance patterns. The detection rate of NTM was 4% (41/1 013), among which Midu County had the highest detection rate (0.89%, 9/1 013). The spatial distribution showed that the number of MTB resistant strains among counties and cities had a negative spatial correlation (Moran′s I value was -0.367, P<0.05). It shows that there is no clustering of drug resistance among counties and cities, and the resistance is serious in individual counties and cities. Yongping County and Nanjian Yi Autonomous County had low and high aggregation, and Yunlong County had high and low aggregation. Conclusions:The drug resistance of MTB showed an rising trend in Dali Bai Autonomous Prefecture from 2017 to 2019. The number of drug-resistant strains among regions was not randomly distributed, the regional difference was large, and spatial autocorrelation analysis provided theoretical clues and basis for the formulation of drug resistance prevention and control measures for tuberculosis in the whole state.

Development of thoracolumbar vertebra (TLV) and rib primordium (RP) is a common evolutionary feature across vertebrates, although whole-organism analysis of the expression dynamics of TLV- and RP-related genes has been lacking. Here, we investigated the single-cell transcriptome landscape of thoracic vertebra (TV), lumbar vertebra (LV), and RP cells from a pig embryo at 27 days post-fertilization (dpf) and identified six cell types with distinct gene expression signatures. In-depth dissection of the gene expression dynamics and RNA velocity revealed a coupled process of osteogenesis and angiogenesis during TLV and RP development. Further analysis of cell type-specific and strand-specific expression uncovered the extremely high level of HOXA10 3'-UTR sequence specific to osteoblasts of LV cells, which may function as anti-HOXA10-antisense by counteracting the HOXA10-antisense effect to determine TLV transition. Thus, this work provides a valuable resource for understanding embryonic osteogenesis and angiogenesis underlying vertebrate TLV and RP development at the cell type-specific resolution, which serves as a comprehensive view on the transcriptional profile of animal embryo development.
