Abstract
BACKGROUND Hand hygiene is a critical strategy for infection prevention in all healthcare settings. Automated electronic monitoring systems are expected to improve hand hygiene performance. AIM To investigate the impact of the Internet of Things (IoT) management system on hand hygiene compliance among medical staff in an emergency intensive care unit (EICU). METHODS This retrospective observational study was conducted between July 1st, 2017 and February 28th, 2018 in a 19-bed EICU. The changes in hand hygiene compliance among 54 members of medical staff and the incidence of hospital infections were compared, counted, and analysed before and after implementing the IoT management system in the EICU that was initiated on November 1st, 2017. FINDINGS After the application of the IoT management system, the hand hygiene compliance rates among the members of the medical staff before (29.5% (3347/11,338) vs 57.9% (4690/8094), P < 0.001) and after (59.9% (9915/16,556) vs 73.8% (17,194/23 286), P < 0.001) the contact with patients and surrounding environment significantly improved. However, hand hygiene compliance among three cleaning staff did not significantly improve after the application. Moreover, there was no significant difference in healthcare-acquired infection rates (2.535% (9/355) vs 2.047% (7/342), P = 0.667) nor in the detection rates of the four major multidrug-resistant bacteria in the EICU before and after the application of the IoT management system (P > 0.05). CONCLUSION The IoT management system significantly improved hand hygiene compliance among medical staff, except cleaners, in the EICU of one provincial hospital; however, the rates of nosocomial infection did not significantly decrease. The quality of hand hygiene implementation needs to be improved.

Abstract
Three volumes of Shiyi Xinjian, written by Zan Yin of Tang Dynasty, contains the theories and prescriptions of food treatment in various branches, which have far-reaching influence on food treatment and clinical treatment. The book was written in the 9th century A. D. as a dietary therapy prescription. In the Northern Song Dynasty, the book of Shiyi Xinjian was still surviving. It has been cited in Taiping Shenghuifang: Shizhi, Yanglao Fengqinshu, Zhenglei Bencao(, Classified Materia Medica from Historical Classics for Emergency) and Shengji Zonglu: Shizhimen. After the Jingkang Incident, the book was rare, and even may have been lost. Until the Ming Dynasty, the book was completely disappeared in China. However, there are some Quotes in the book Zhenglei Bencao and other books, and the contents of this book are still often cited by later medical books. After that, the Japanese collected 211 prescriptions of Shiyi Xinjian from Euibangyoochui in Korea. Luo Zhenyu brought them back to China and published them in the Dongfang Xuehui in 1924, which made the Shiyi Xinjian appear in a separate volume in China for the first time since it was lost, which promoted the spread of the book in China. After the founding of the People's Republic of China, some of the scholars collected it again, which improved the content of the book.

Abstract
CLINICAL RELEVANCE Acid-functional monomers in self-adhesive resin cements may decrease their self-curing polymerization ability. Light irradiation optimizes polymerization performance. SUMMARY Purpose: The aim of this study was to investigate Knoop microhardness of self-adhesive resin cements under dual- and self-curing modes in simulated canals for describing the polymerization behavior.Methods and Materials: Slots in lightproof silicone cylinders with one open end were filled with the following eight materials: a traditional resin cement (Duolink), a core build-up resin material (MultiCore Flow), and six self-adhesive resin cements (RelyX Unicem 2, G-Cem Automix, Maxcem, Biscem, Multilink Speed, and PermaCem 2.0). The resins were exposed to light through the open end and then stored in a lightproof box. The Knoop hardness gradient for each resin was measured after 1 hour and 120 hours. Surface readings were obtained at 1-mm intervals from 1 mm to 10 mm away from the open ends. The data were analyzed by two-way analysis of variance and the Student-Newman-Keuls test (α=0.05).Results: All the resin materials had stable Knoop hardness numbers (KHNs) at a certain depth; their KHNs in the self-curing mode did not change (p>0.05). The region above this certain depth was regarded as having undergone the dual-curing mode, and the KHN decreased gradually with depth (p<0.05). Between 1 and 120 hours postexposure, the ratio of the KHN at a 5-mm depth (self-cured) to that at a 1-mm depth (dual-cured) increased in Duolink and MultiCore Flow. However, the ratios of the six adhesive resin cements varied.Conclusion: Without light, most self-adhesive resin cements differed from traditional dual-cured resin materials in terms of Knoop micro-hardness, and they had a lesser capacity for chemical-induced curing.

Abstract
The gut microbiome functions like an endocrine organ, generating bioactive metabolites, enzymes or small molecules that can impact host physiology. Gut dysbacteriosis is associated with many intestinal diseases including (but not limited to) inflammatory bowel disease, primary sclerosing cholangitis-IBD, irritable bowel syndrome, chronic constipation, osmotic diarrhoea and colorectal cancer. The potential pathogenic mechanism of gut dysbacteriosis associated with intestinal diseases includes the alteration of composition of gut microbiota as well as the gut microbiota-derived signalling molecules. The many correlations between the latter and the susceptibility for intestinal diseases has placed a spotlight on the gut microbiome as a potential novel target for therapeutics. Currently, faecal microbial transplantation, dietary interventions, use of probiotics, prebiotics and drugs are the major therapeutic tools utilized to impact dysbacteriosis and associated intestinal diseases. In this review, we systematically summarized the role of intestinal microbiome in the occurrence and development of intestinal diseases. The potential mechanism of the complex interplay between gut dysbacteriosis and intestinal diseases, and the treatment methods are also highlighted.

Abstract
Background:Ankylosing spondylitis (AS) is strongly associated with the genetic marker HLA-B27. Approximately 80%-90% of white patients with AS express HLA-B27 compared with < 8% of the general population. In patients with AS, negative HLA-B27 status is a predictor of worse response to TNFis.1The impact of HLA-B27 status on clinical efficacy of secukinumab, a fully human monoclonal antibody that selectively inhibits IL-17A, has not been studied.Objectives:To analyze the impact of HLA-B27 status on clinical outcomes at Week 16 in patients with AS treated with secukinumab vs placebo.Methods:Patients with AS were pooled from the MEASURE 1-4 studies (NCT01358175,NCT01649375,NCT02008916, andNCT02159053) and stratified by HLA-B27 status. All trials included patients who received secukinumab 150 mg every 4 weeks with or without an initial loading dose (10 mg/kg IV at Weeks 0, 2, 4 or 150 mg SC at Weeks 0, 1, 2, and 3) or placebo control. MEASURE 3 included patients receiving secukinumab 300 mg every 4 weeks following the initial IV loading dose. Efficacy at Week 16 was determined by the proportion of patients achieving ASAS20/40, ASAS5/6, ASAS partial remission, BASDAI50, ASDAS-CRP < 2.1, ASDAS-CRP < 1.3, and improvement in Patient Global Assessment (VAS) and total spinal/back pain (VAS) scores. In MEASURE 1, 2, and 4, quality of life (QOL) was assessed at Week 16 by the SF-36 PCS, SF-36 MCS, and ASQOL. ASAS, BASDAI, and ASDAS-CRP responses were analyzed by nonresponder imputation, and all other outcomes by mixed models for repeated measures. For hypothesis generation, outcomes at Week 16 with secukinumab vs placebo within HLA-B27 strata were compared by logistic regression analysis without adjustment for multiple comparisons.Results:Baseline characteristics were balanced across treatment groups, although more HLA-B27+ patients than HLA-B27− patients were male (71%-73% vs 43%-50%). HLA-B27+ patients receiving any dose of secukinumab were significantly more likely to achieve ASAS, BASDAI50, and ASDAS-CRP responses vs those receiving placebo (P< .05; Figure 1). HLA-B27− patients receiving secukinumab 300 mg were significantly more likely to achieve ASAS40, ASAS partial remission (Figure 1A), and BASDAI50 (Figure 1B) responses than those receiving placebo (P< .05). Patients receiving any dose of secukinumab were more likely to achieve ASAS5/6 and ASDAS-CRP < 2.1 than those receiving placebo, regardless of HLA-B27 status (P< .05; Figure 1B). All secukinumab-treated patients experienced significant improvement in Patient Global Assessment at Week 16 vs placebo, regardless of HLA-B27 status, while only HLA-B27+ patients experienced significant reduction in total spinal/back pain vs placebo (P< .05; Figure 2A). Numerical improvements in QOL were observed in all patients receiving secukinumab 150 mg vs placebo; these reached significance for HLA-B27+ patients (Figure 2B).Conclusion:Secukinumab is effective in patients with AS regardless of HLA-B27 status; HLA-B27+ patients may derive increased therapeutic benefit compared with HLA-B27− patients.Reference:[1]Alazmi M, et al.Arthritis Care Res (Hoboken). 2018;70:1393-9.Acknowledgments:This study was funded by Novartis Pharmaceuticals Corporation.

Abstract
Background:Ankylosing spondylitis (AS) is a chronic inflammatory disease of the axial skeleton associated with pain, stiffness, and disability.1Up to 66% of patients (pts) with AS may also have peripheral involvement, including swollen and tender joints (STJs),2,3which are associated with worse overall disease activity.4A previous analysis showed that secukinumab, a selective inhibitor of interleukin 17A, led to significant improvements in efficacy outcomes vs placebo, regardless of peripheral joint involvement.3However, the effect of secukinumab on symptoms of peripheral arthritis in pts with AS was not assessed.Objectives:The objective of this analysis was to assess changes in peripheral symptoms in pts with AS treated with secukinumab vs placebo.Methods:Data from pts with active AS and peripheral symptoms who were enrolled in MEASURE 1 (NCT01358175), 2 (NCT01649375), 3 (NCT02008916), and 4 (NCT02159053) were pooled in this post hoc, hypothesis-generating analysis. No adjustments for multiple comparisons were made. Pts with peripheral symptoms were identified by the presence of STJs, based on 44-joint counts at baseline (BL). Pts received subcutaneous (SC) secukinumab every 4 weeks at doses of 300 mg with an intravenous (IV) loading dose (MEASURE 3 only), 150 mg with an IV or SC loading dose, or placebo. Treatment response through Week 16 was assessed based on the proportions of pts who achieved improvements of 20%, 50%, 70%, or 100% in the number of swollen and number of tender joints and improvements in the BASDAI score for question 3 and Patient Global Assessment (PGA). Changes in the number of swollen and number of tender joints were assessed in pts with swollen or tender joints at BL, respectively.Results:This pooled analysis included 560 pts with AS and STJs at BL (Table). At Week 16, treatment with secukinumab led to significantly greater proportions of pts achieving reductions in the number of swollen (Fig 1A) or tender (Fig 1B) joints compared with placebo; the treatment effect was more pronounced in reduction of swollen joints. Furthermore, a greater proportion of secukinumab-treated pts achieved complete resolution of swollen or tender joints vs placebo (Fig 1). Secukinumab also led to significant improvements in peripheral pain/swelling (Fig 2A) and disease activity (Fig 2B) vs placebo, as assessed using BASDAI question 3 and the PGA, respectively.Table.Patient Characteristics at BaselineSecukinumabPlacebo (n = 252)300 mg (n = 52)150 mg (n = 256)Age, mean, y43.643.744.9Time since diagnosis, mean, y5.67.27.3Male, %63.562.157.5PGA of Disease Activity, mean, mm73.471.770.1BASDAI question 3, mean6.36.66.4Swollen 44-joint count, mean1.92.62.5Tender 44-joint count, mean7.17.87.9Conclusion:In parallel with its previously reported efficacy in axial symptoms,3secukinumab led to significant improvements in symptoms of peripheral arthritis in pts with AS.

Abstract
The regulatory function of histone acetylation in the expression of genes encoding heat shock proteins (Hsps) has been documented in Drosophila melanogaster; however, knowledge of the role of acetylation in modulating Hsps in other insect pests is limited. In this study, two full-length cDNAs encoding inducible Hsp70 (designated TcHsp70) and heat shock cognate 70 (TcHsc70) were isolated and characterized in the red flour beetle, Tribolium castaneum. TcHsp70 and TcHsc70 cDNAs were 2256 and 2132 bp and encoded 1941- and 1893-bp open reading frames, respectively. The deduced TcHsp70 and TcHsc70 proteins contained 646 and 630 amino acids, respectively, and contained sequences typical of the Hsp70 family, including the EEVD motif for cytoplasmic localization. Expression patterns after heat shock indicated that TcHsp70 was strongly heat-inducible, whereas the expression level of TcHsc70 remained unchanged under heat shock. RNA interference-mediated knock-down of three genes encoding class I histone deacetylases differentially influenced both basal and heat shock inducible expression of TcHsp70 and TcHsc70, suggesting the involvement of histone acetylation in epigenetic regulation of Hsp70 transcription in T. castaneum.

Inhibition of microRNA-875-5p promotes radioiodine uptake in poorly differentiated thyroid carcinoma cells by upregulating sodium-iodide symporter. J Endocrinol Invest 2020; 43:439-450. [PMID: 31612419 DOI: 10.1007/s40618-019-01125-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Accepted: 09/25/2019] [Indexed: 01/22/2023]
Abstract
BACKGROUND AND AIM Poorly differentiated thyroid carcinoma (PDTC) is an endocrine malignancy that is challenging to treat due to its limited radioiodine uptake. microRNAs (miRNAs or miRs) have been shown to be useful in treating many types of tumors, including PDTC. This study aims to evaluate the potential effect of miR-875-5p on the radioiodine uptake of PDTC and to clarify the underlying mechanisms. METHODS Expression of miR-875-5p and sodium-iodide symporter (NIS) in tissues and cell lines was determined using RT-qPCR. The binding relationship between miR-875-5p and NIS was predicted through in silico analysis and verified by dual-luciferase reporter gene assay. A series of miR-875-5p mimic, miR-875-5p inhibitor, shRNA against NIS, and overexpressed NIS plasmids were introduced into PDTC cells. We then evaluated the cell viability, colony formation, apoptosis, and radioiodine uptake of each PDTC sample via CCK-8 assay, clonogenic assay, flow cytometry, and γ counter, respectively. RESULTS miR-875-5p was found to be highly expressed, but NIS was poorly expressed in DTC tissues and PDTC cell lines. NIS was verified to be a target gene of miR-875-5p. Upregulation of miR-875-5p was found to induce PDTC cell proliferation, and reduce apoptosis and radioiodine uptake in vitro through down-regulation of NIS. In an in vivo orthotopic model, the enhancement of miR-875-5p led to the reduction of NIS expression and radioiodine uptake in the thyroid tumors. CONCLUSIONS Altogether, the findings of the current study suggest that down-regulated miR-875-5p expression could promote its target gene NIS to increase radioiodine uptake in PDTC, constituting a preventive strategy against PDTC.

Abstract
PURPOSE To investigate the role of PRDX2 in esophageal carcinoma (ESCA). METHODS The expression of PRDX2 was detected in ESCA tissues. And PRDX2 expression in two ESCA cell lines was knocked down. Cell proliferation, metastasis and invasion were detected in these cells. RESULTS Here, we found that PRDX2 expression was significantly increased in ESCA tissues and was associated with a poor prognosis in ESCA patients. In addition, PRDX2 expression was significantly associated with pathological grading, infiltration degree and 5-year survival time in ESCA patients. Next, we knocked down PRDX2 expression by PRDX2-shRNA transfection in two ESCA cell lines, Eca-109 and TE-1. Proliferation analysis indicated that in vitro PRDX2 knockdown decreased growth and clone formation of ESCA cells. Scratch and transwell assays indicated that cell migration and invasion were significantly inhibited by PRDX2 knockdown. In addition, PRDX2 knockdown inhibited cell cycle of ESCA cells and down-regulated Cyclin D1-CDK4/6. Moreover, PRDX2 knockdown regulated proteins involved in mitochondrial-dependent apoptosis, including increased Bax and Caspase9/3 and decreased Bcl2. Mechanism investigation indicated that PRDX2 knockdown led to inactivation of Wnt/β-catenin and AKT pathways. CONCLUSIONS Our data suggest that PRDX2 may function as an oncogene in the development of ESCA via regulating Wnt/β-catenin and AKT pathways. Our study fills a gap in the understanding of the role of PRDX2 in ESCA and provides a potential target for ESCA treatment.
