Objective To standardize the job training and improve the basic professional quality and induction ability of practitioners in Blood Services by setting up job training assessment standardized model.Methods Using the standardize model to carry out the application of standardized model of job training assessment for the practitioners in Blood Services.July 2016-June 2017,focusing on the standardize training materials and training standards to carry out the centralized training,establishing a unified teacher library of the province and the centralized training will be taught by those teachers,evaluating result by standardize theoretical test and the conformity standard,then evaluating and supervising the assessment results.Results 356 practitioners participated in centralized training,379 practitioners participated in the theoretical test,and 339 practitioners were qualified of the actual operation during these two years.The total qualified rate is 89.4%.There was no significant difference in the qualified rate between two years (P>0.05).Among them,the qualified rate of category Ⅰ personnel was 85.1%,category Ⅱ personnel was 98.7%,category Ⅲ personnel was 94.8%,and the qualified rate of category Ⅱand Ⅲ was higher than that of category Ⅰ (P<0.05).Conclusion Through the application of the standardized model to promote the standardization of education and training resource standard,and carry on standardized training evaluation as well as strictly grasp the examination and evaluation standards,it will be conducive to improving the quality of education and training,will also be conducive to improving the professional quality of employees and supply institutions.

Objective:
To investigate the efficacy and safety of the recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein (rhTNFR: Fc, etanercept) for the treatment of occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) .
Methods:
In September 2011 to February 2016, 12 patients with OMLDT were treated with etanercept 25 mg, subcutaneous injection, twice per week, doubling of first dose. The course of treatment was 6 weeks. The drug eruption area and severity index (DASI) score, the proportion of patients achieving a 50%, 75% and 90% reduction in DASI (DASI50, DASI75, DASI90) and the serum level of TNF-α were used to assess the efficacy at different times. Adverse reactions were also recorded and evaluated. The results were statistically analyzed by nonparametric Friedman test and repetitive measurement ANOVA using the software SPSS19.0.
Results:
After 4 weeks treatment, the DASI score decreased form 56.33±7.02 to 0.50±0.91 (

Osteoporosis is one of the common complications of type 2 diabetes mellitus (T2DM). Recent studies have shown that glucagon-like peptide-1 receptor agonists (GLP-1RAs) can promote bone formation and inhibit bone resorption, suggesting that this hypoglycemic drugs may benefit T2DM patients with osteoporosis and high fracture risk, but its underlying mechanism is not fully understood, and different GLP-1RAs exhibit different skeletal effects and molecular mechanisms. In this paper, the effects of several GLP-1RAs on bone metabolism are reviewed.

BACKGROUND:
The switch/sucrose nonfermentable chromatin-remodeling (SWI/SNF) complex is a pivotal chromatin remodeling complex, and the genomic alterations (GAs) of the SWI/SNF complex are observed in several cancer types, correlating with multiple biological features of tumor cells. However, their role in liver metastasis of non-small cell lung cancer (NSCLC) remains unclear. Our study aims to investigate the role and potential mechanisms underlying NSCLC liver metastasis induced by the GAs of SWI/SNF complex.
METHODS:
The GAs of SWI/SNF complex in NSCLC cell lines (H1299, H23 and H460) were identified by whole-exome sequencing (WES). ARID1A knockout H1299 cell was constructed with the CRISPR/Cas9 technology. The mouse model of liver metastasis from NSCLC was established to simulate lung cancer liver metastasis and observe the metastasis rate under different gene mutation conditions. RNA sequencing and Western blot were conducted for differential gene expression analysis. Immunohistochemistry (IHC) analysis was used to assess protein expression levels of SWI/SNF-regulated target molecules in mouse liver metastases.
RESULTS:
WES analysis revealed intracellular gene mutations. The animal experiments demonstrated a correlation between the GAs of SWI/SNF complex and a higher liver metastasis rate in immunodeficient mice. Transcriptome sequencing and Western blot analysis showed upregulated expression of ALDH1A1 and APOBEC3B in SWI/SNF-mut cells, particularly in ARID1A-deficient H460 and H1299 sgARID1A cells. IHC staining of mouse liver metastases further demonstrated elevated expression of ALDH1A1 in the H460 and H1299 sgARID1A group.
CONCLUSIONS
This study underscores the critical role of the GAs of SWI/SNF complex, such as ARID1A and SMARCA4, in promoting liver metastasis of lung cancer cells. The GAs of SWI/SNF complex may promote liver-specific metastasis by upregulating ALDH1A1 and APOBEC3B expression, providing novel insights into the molecular mechanisms underlying lung cancer liver metastasis.
