Abstract
Parathyroid hormone (PTH) is a crucial regulator of calcium homeostasis and bone remodeling, and the parathyroid hormone 1 receptor (PTH1R) belongs to a class II G-protein-coupled receptor. PTH activates PTH1R, which mediates catabolic and anabolic processes in the skeleton. However, the functional mechanism of PTH1R has not been thoroughly elucidated in organisms. This study identified a 51 bp indel mutation in the first intron of the PTH1R gene and elucidated the effect of this gene mutation on the growth and carcass traits in chickens. The results indicated that the 51 bp indel was significantly associated with subcutaneous fat thickness, abdominal fat weight, body weight and daily gain over 4-8 weeks. Furthermore, we found that PTH1R gene expression was highest in the kidney and liver tissues, and it showed a trend of decreasing in leg and breast muscle tissues at different embryonic stages. In addition, we examined the expression of the three genotypes of the PTH1R gene in the liver, breast muscle and abdominal fat and found that the II genotype was significantly higher than the DD and ID genotypes. In summary, these findings suggest that the PTH1R gene can serve as a potential molecular marker for chicken breeding.

Abstract
AIM Type 2 diabetes is a major global epidemic affecting over 400 million people worldwide. The objective of this systematic review was to provide an overview of recommendations from clinical practice guidelines (guidelines) addressing non-insulin based pharmacological management of among non-pregnant adults in an outpatient setting, and critically appraise their methodological development. METHODS We systematically searched MEDLINE and Embase databases, for relevant guidelines using the Ovid interface. We scanned the bibliographies of all eligible guidelines for additional relevant citations. Teams of two reviewers, independently and in duplicate, screened titles and abstracts and potentially eligible full text reports to determine eligibility and appraised the reporting quality of guidelines using the Advancing Guideline Development, Reporting and Evaluation in Health Care instrument II (AGREE II) instrument. RESULTS Our search yielded 11264 unique citations, of which 124 were retrieved for full-text review; 17 guidelines proved eligible. The highest scoring AGREE domain was 'clarity of presentation' (66%; range 7-92%), followed by 'scope and purpose' (58%; range 25-92%), 'editorial independence' (55%; range 0-91%), 'stakeholder involvement' (45%; range 11-90%) and 'rigour of development' (43%; range 4-92%). The poorest domain was 'applicability' (37%; range 6-84%). The guidelines authored by the World Health Organization group achieved the highest AGREE overall score. CONCLUSIONS Most of the guidelines provided recommendations with a local jurisdictional focus and showed significant variation in the quality. Nevertheless, only a small number of those scored well overall.

Abstract
Abstract
Background
Controversy exists regarding the use of beta-blockers (BBs) among patients with acute myocardial infarction (AMI) in contemporary reperfusion era. Previous studies predominantly focused on beta-blockers prescribed at discharge, and the effect of long-term adherence to beta-blocker on major adverse cardiovascular events (MACE) remains unclear.
Objective
To explore the association between long-term beta-blocker use patterns and MACE among contemporary AMI patients.
Methods
We enrolled 7860 patients with AMI, who were discharged alive and prescribed with BBs based on CAMI registry from January 2013 to September 2014. Patients were divided into two groups according to BBs use pattern: Always users group (n=4476) were defined as patients reporting BBs use at both 6- and 12-month follow-up; Inconsistent users group were defined as patients reporting at least once not using BBs at 6- or 12-month follow-up. Primary outcome was defined as MACE at 24-month follow-up, including all-cause death, non-fatal MI and repeat-revascularization. Multivariable cox proportional hazards regression model was used to assess the association between BBs and MACE.
Results
Baseline characteristics are shown in table 1. At 2-year follow-up, 518 patients in inconsistent users group (15.6%) and 548 patients in always users group (12.3%) had MACE. After multivariable adjustment, inconsistent use of BBs was associated with higher risk of MACE (HR: 1.323, 95% CI: 1.171–1.493, p<0.001).
Table 1 Baseline characteristics Variable Always user (N=4476) Inconsistent user (N=3384) P value Age (years) 60.6±12.0 61.2±12.2 <0.001 Male 3381 (75.7%) 2461 (74.3%) 0.084 Diabetes 892 (20.0%) 610 (18.4%) 0.003 Hypertension 2372 (53.2%) 1543 (46.6%) <0.001 Dyslipidemia 244 (5.5%) 126 (3.8%) <0.001 Prior myocardial infarction 351 (7.9%) 232 (7.0%) <0.001 Heart failure 88 (2.0%) 63 (1.9%) <0.001 Chronic obstructive pulmonary disease 66 (1.5%) 60 (1.8%) <0.001 Current smoker 2054 (46.1%) 1579 (47.8%) 0.179 Left ventricular ejection fraction (%) 53.7±11.48 54.0±10.9 <0.001 Major Adverse Cardiovascular Events 548 (12.3%) 518 (15.6%) <0.001
Conclusions
Our results showed consistent BBs use was associated with reduced risk of MACE among patients with AMI managed by contemporary treatment.

Abstract
This study aimed to assess the distribution of pathotypes in primary nephrotic syndrome (PNS) and their relationship with glucocorticoid treatment efficacy. The study included 120 patients who were treated in the nephrology, internal medicine and pediatrics wards of The Second Affiliated Hospital of Qiqihar Medical University between March 2014 and October 2017 and who underwent renal biopsy to confirm PNS. The patients with PNS were divided into a child group (40 cases, aged 0~17 years) and an adult group (80 cases, aged over 18 years). We evaluated the correlation of the curative effect of glucocorticoid with age, pathological type, renal tubulointerstitial damage retinol binding protein and total urine protein. The main pathological types of PNS were glomerular minor lesion (GML) and mesangial proliferative nephritis (MPGN). The glucocorticoid treatment had an improved effect on children compared to adults, and also the effect decreased with age. The pathotypes of PNS were correlated with hormone resistance: tubulointerstitial lesions were associated with glucocorticoid resistance which was also associated with the degree of tubular damage. In both adults and children the retinol binding protein (RBP) urinary levels were positively associated with the degree of renal tubular injury. In conclusion, age, pathological type, renal tubulointerstitial damage, and RBP urinary level were related to the therapeutic effect of glucocorticoid treatment in adults and children with PNS.

Abstract
Farrerol was found to possess neuroprotective effect; however, the mechanism remains unknown. The aim of the present study was to explore the effect of farrerol on MPP+ -induced inflammation in mouse microglial BV-2 cells and to elaborate the underlying mechanism. MTT assay was performed to measure the cell viability. The pro-inflammatory mediators and cytokines including interleukin (IL)-6, IL-1β, and tumor necrosis factor-α (TNF-α); inducible nitric oxide synthase; and cyclooxygenase 2 were measured. The expression of p-p65, p-IκBα, toll-like receptor 4 (TLR4), and myeloid differentiation primary response 88 were analyzed by western blot. We found that farrerol treatment improved cell viability in MPP+ -induced BV-2 cells. MPP+ -induced upregulation of IL-6, IL-1β, and TNF-α was inhibited by farrerol treatment. Farrerol treatment also attenuated MPP+ -induced expression of inducible nitric oxide synthase and cyclooxygenase 2 as well as the activation of NF-κB in BV-2 cells. MPP+ -induced TLR4 signaling was markedly diminished by farrerol treatment. Knockdown of TLR4 attenuated MPP+ -induced inflammatory response in BV-2 cells. In conclusion, farrerol treatment attenuated MPP+ -induced inflammatory response by inhibiting the TLR4 signaling pathway in BV-2 cells. The results indicated that farrerol could be used as a therapeutic agent for preventing or alleviating the neuroinflammation-related diseases, such as Parkinson's disease.

Abstract
Nucleotide-binding, oligomerization domain (NOD)-like receptor family, pyrin domain containing 3 (NLRP3) gene polymorphism was reported to be associated with susceptibility, disease activity or anti-tumour necrosis factor (TNF) treatment response in rheumatoid arthritis (RA). However, the roles of NLRP3 inflammasome in the development of RA have not yet been elucidated fully. The present study aimed to study the role of NLRP3 inflammasome in RA. NLRP3 inflammasome activation in synovial tissues from RA and osteoarthritis (OA) patients were assessed by Western blot. Active caspase-1 in synovia was stained by a FAM-FLICA caspase-1 probe. Mice with collagen-induced arthritis (CIA) were treated with MCC950, a selective NLRP3 inhibitor, or vehicle for 2 weeks. The clinical score of arthritis, synovial inflammation and cartilage erosion were assessed. Proinflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that NLRP3 inflammasome was highly activated in both synovia from RA patients and CIA mice. Activation of NLRP3 inflammasome occurred mainly in the infiltrating monocyte/macrophages in synovia, but not in fibroblast-like synoviocytes. Treatment with MCC950 resulted in significantly less severe joints inflammation and bone destruction. NLRP3 inflammasome activation in the synovia was inhibited significantly by MCC950 with reduced production of interleukin (IL)-1β. The inhibition of NLRP3 inflammasome activation by MCC950 was confirmed further in a human monocytic cell line, THP-1. In conclusion, NLRP3 inflammasome is involved in the pathogenesis of RA. Targeting NLRP3 inflammasome with a small molecule inhibitor might be a novel therapeutic strategy for RA.

Abstract
Phosphorus (P) eutrophication is a major pollution problem globally, with unprecedented amount of P emanating from agricultural sources. But little is known about the optimization of soil-biochar P sorption capacity. The study objective was to determine how biochar feedstocks and pyrolysis conditions influences carbon (C) thermal stability, C composition and pH and in turn influence the phosphorus sorption optimization. Biochar was produced from switchgrass, kudzu and Chinese tallow at 200, 300, 400, 500, 550, 650,750 °C. Carbon thermal stability was determined by multi-element scanning thermal analysis (MESTA), C composition was determined using solid state 13C NMR. Phosphorus sorption was determined using a mixture of 10% biochar and 90% sandy soil after incubation. Results indicate increased P sorption (P < 0.0001) and decreased P availability (P < 0.0001) with increasing biochar pyrolysis temperature. However, optimum P sorption was feedstock specific with switchgrass indicating P desorption between 200 and 550 °C. Phosphorus sorption was in the order of kudzu > switchgrass > Chinese tallow. Total C, C thermal stability, aromatic C and alkalinity increased with elevated pyrolysis temperature. Biochar alkalinity favored P sorption. There was a positive relationship between high thermal stable C and P sorption for Kudzu (r = 0.62; P = 0.0346) and Chinese tallow (r = 0.73; P = 0.0138). In conclusion, biochar has potential for P eutrophication mitigation, however, optimum biochar pyrolysis temperature for P sorption is feedstock specific and in some cases might be out of 300-500 °C temperature range commonly used for agronomic application. High thermal stable C dominated by aromatic C and alkaline pH seem to favor P sorption.

BACKGROUND AND PURPOSE Despite the label change and the FDA's boxed warning added to the Feraheme (ferumoxytol) label in March 2015, radiologists have shown increasing interest in using ferumoxytol as an MR imaging contrast agent as a supplement or alternative to gadolinium. The goals of this study were to provide information regarding ferumoxytol safety as an imaging agent in a single center and to assess how the Feraheme label change may affect this potential, currently off-label indication. MATERIALS AND METHODS This retrospective study evaluated the overall frequency of ferumoxytol-related adverse events when used for CNS MR imaging. Patients with various CNS pathologies were enrolled in institutional review board-approved imaging studies. Ferumoxytol was administered as multiple rapid bolus injections. The risk of adverse events was correlated with demographic data/medical history. RESULTS The safety of 671 ferumoxytol-enhanced MR studies in 331 patients was analyzed. No anaphylactic, life-threatening, or fatal (grade 4 or 5) adverse events were recorded. The overall proportion of ferumoxytol-related grade 1-3 adverse events was 10.6% (8.6% occurring within 48 hours), including hypertension (2.38%), nausea (1.64%), diarrhea (1.04%), and headache (1.04%). History of 1 or 2 allergies was associated with an increased risk of adverse events (14.61% versus 7.51% [no history]; P = .007). CONCLUSIONS The frequency of mild ferumoxytol-related adverse events was comparable with literature results, and no serious adverse event was recorded. Although the recommendations in the boxed warning should be followed, serious adverse events appear to be rare, and with proper precautions, ferumoxytol may be a valuable MR imaging agent.

Abstract
Objective: To investigate natural killer (NK) cell quantities and function in patients with immune thrombocytopenia (ITP) . Methods: A total of 66 ITP patients (34 newly diagnosed and 32 in complete remission) were collected from September 2015 to May 2016 in Tianjin Medical University General Hospital, and 30 healthy volunteers were recruited as controls. The percentages of NK cells and their subsets in peripheral blood, the expression of activating receptor (NKp44), inhibitory receptor (NKG2A) and CD16, perforin and granzyme β were detected by flow cytometry. The correlation between the above parameters and patients' immune status and platelet level were evaluated. Results: (1)The percentage of CD3(-)CD56(+) NK cells in newly diagnosed patients (10.99%±4.89%)and patients in complete remission (9.73%±6.75%) were significantly lower than that in healthy controls (14.67%±7.24%)(P=0.023, 0.003). The percentage of NK cells Bright subset was significantly lower in the newly diagnosed patients(0.48%±0.23%)and those in complete remission (0.41%±0.33%) than in healthy controls(0.64%±0.32%)(P=0.037, 0.002); the percentage of Dim subset was also significantly lower in the newly diagnosed (10.16%±5.02%) and patients in complete remission (8.07%±5.74%) than in healthy controls(14.16%±7.19%) (P=0.009, 0.007). (2)The proportion of Bright subset in total NK cells in new diagnosed ITP patients (6.48%±4.33%) was significantly higher than that in healthy controls (4.21%±2.70%)(P=0.020); the proportion of Dim NK cells subset in new diagnosed ITP patients (93.51%±4.33%) was significantly lower than that in healthy controls(95.79%±2.70%) (P=0.020). (3)The expression of activating receptor NKp44 in new diagnosed ITP patients was significantly lower than that in complete remission group and healthy controls[0.28%(0.95%)vs 0.61%(2.05%), 0.92%(0.90%); P=0.047, 0.048]; the expression of inhibitory receptor NKG2A in new diagnosed ITP patients was significantly higher than that in healthy controls(42.34%±23.86% vs 29.25%±12.83%, P=0.009). The proportion of CD16 was significantly lower in the newly diagnosed patients than in healthy controls(93.51%±4.33%95.79%±2.70%, P=0.020). (4)The expression of perforin in the newly diagnosed ITP patients was significantly lower than that in healthy controls [87.52%(25.29%)vs 91.55%(8.29%), P=0.025]; the expression of granzyme β in ITP patients and controls showed no statistically significant difference. (5)The level of NK cells in ITP patients was negatively correlated with CD3(+) CD8(+) T cells (r=-0.387, P=0.012) and CD5(+) CD19(+) B cells in peripheral blood (r=-0.273, P=0.028), positively correlated with the ratio of CD3(+) CD4(+) /CD3(+) CD8(+) (r=0.358, P=0.028) and peripheral platelet count (r=0.314, P=0.011). Conclusion: Deceased quantities and impaired total NK function, insufficient suppression of autoreactive T and B cells might play a role in the pathogenesis of ITP.
