The registry and analysis of occupational exposure is significant for radiation protection against ionising radiation. This paper presents the current status of the 'Chinese Registry of Radiation Workers (CRRW)' and trends as well as the distribution of occupational exposure to ionising radiation in China from 2009 to 2018. A database with total 6.6 million monitoring records from 820 000 workers in 85 000 radiation units for medical uses, industrial uses and miscellaneous uses is established by the CRRW. The Mann-Kendall test shows statistically significant decreasing trends of average annual effective dose for the total, medical uses and industrial uses (p less then 0.01), by 0.035, 0.042 and 0.020 mSv/y, respectively. The average annual effective dose for the monitored workers is 0.403 mSv for the 10-y period. More than 96.1% of the monitored workers receive annual doses less than the limit for public exposure (1 mSv) in 2018. The annual average effective dose in medical uses is significantly higher than industrial uses and miscellaneous uses (p less then 0.05/3 = 0.017). In 2018, the annual collective dose of 107.41 man·Sv is received by 378 428 monitored workers, with medical uses as the dominant contributor. These observations could be a result of improvements in radiation protection practices in China. However, it is still necessary to take rigorous and continuous surveillance and radiation protection measures, to keep individual dose as low as reasonably achievable, especially for those found to receive relatively higher doses in medical uses.
To determine causal associations between genetically predicted TNF-α, IL-12p70 and IL-17 levels and risk of PsA.

The publicly available summary-level findings from genome-wide association studies (GWAS) was used to identify loci influencing normal physiological concentrations of TNF-α, IL-12p70 and IL-17 (n = 8293) among healthy individuals as exposure and a GWAS for PsA from the UK Biobank (PsA = 900, control = 462033) as the outcome. A two-sample Mendelian randomization (MR) analysis was performed using the inverse-variance weighted (IVW), weighted median and MR-Egger regression methods. Sensitivity analysis and MR-Egger regression analysis were performed to evaluate the heterogeneity and pleiotropic effects of each variant.

Single-nucleotide polymorphisms (SNPs) at genome-wide significance from GWASs on TNF-α, IL-12p70 and IL-17 were identified as the instrumental variables. The IVW method indicated a causal association between increased IL-17 level and risk of PsA (β = -0.00186 per allele, s.e. = 0.00043, P = 0.002). Zebularine in vivo Results were consistent in the weighted median method (β = -0.00145 per allele, s.e. = 0.00059, P = 0.014) although the MR-Egger method suggested a non-significant association (β = -0.00133 per allele, s.e. = 0.00087; P = 0.087). Single SNP MR results revealed that the C allele of rs117556572 was robustly associated with risk of PsA (β = 0.00210, s.e. = 0.00069, P = 0.002). However, no evidence for a causal effect was observed between TNF-α, IL-12p70, decreased IL-17 levels and risk of PsA.

Our findings provide preliminary evidence that genetic variants predisposing to higher physiological IL-17 level are associated with decreased risk of PsA.

In Arabidopsis thaliana, Fe starvation limits infection by necrotrophic pathogens. Here, we report that Fe deficiency also reduces disease caused by the hemi-biotrophic bacterium Pseudomonas syringae and the biotrophic oomycete Hyaloperonospora arabidopsidis, indicating that Fe deficiency-induced resistance is effective against pathogens with different lifestyles. Furthermore, we show that Fe deficiency-induced resistance is not caused by withholding Fe from the pathogen but is a plant-mediated defense response that requires activity of ethylene and salicylic acid. Because rhizobacteria-induced systemic resistance (ISR) is associated with a transient up-regulation of the Fe deficiency response, we tested whether Fe deficiency-induced resistance and ISR are similarly regulated. However, Fe deficiency-induced resistance functions independently of the ISR regulators MYB72 and BGLU42, indicating that both types of induced resistance are regulated in a different manner. Mutants opt3 and frd1, which display misregulated Fe homeostasis under Fe-sufficient conditions, show disease resistance levels comparable with those of Fe-starved wild-type plants. Our results suggest that disturbance of Fe homeostasis, through Fe starvation stress or other non-homeostatic conditions, is sufficient to prime the plant immune system for enhanced defense.
To analyse the effectiveness of tofacitinib for the treatment of refractory skin thickening in dcSSc.

Data from 10 patients with dcSSc treated with tofacitinib (5 mg twice daily) were analysed. A total of 12 dcSSc patients treated with intensive conventional immunosuppressants were selected as the historical comparator group. A clinically relevant response was defined as a decrease in the modified Rodnan skin score (mRSS) of >5 points and ≥25% from baseline. Clinical indicators were compared between the two groups to evaluate the effect of tofacitinib.

The mRSS significantly improved the first month after tofacitinib treatment, with a mean change in the mRSS of -3.7 (95% CI -5.52, -1.88; P = 0.001) and greater than the comparators at 6 months [-10.0 (95% CI -14.74, -5.26) vs -4.1 (95% CI -7.49, -0.73), P = 0.026]. Tofacitinib-treated patients had a significantly shorter response time than the comparators (P = 0.015 by log-rank test), with overall response rates of 20% (2/10) vs 0% (0/12) and 60% (6/10) vs 16.7% (2/12) at 1 and 3 months, respectively.

Our results indicate that tofacitinib may be as effective as or even better than intensive conventional immunosuppressants, with a quicker and higher response rate in refractory dcSSc patients with progressive skin thickness.
