Abstract
Experiments on the swimming kinetics and behaviour of weather loach Misgurnus anguillicaudatus showed that horizontal swim speed was significantly greater than swim speeds when ascending to or descending from the water surface to gulp air. Vertical swimming speeds during ascending or descending were similar. Misgurnus anguillicaudatus swam unsteadily during vertical movements compared with horizontal movements.

Associations between endogenous sex hormones and MRI structural changes in patients with symptomatic knee osteoarthritis. Osteoarthritis Cartilage 2017; 25:1100-1106. [PMID: 28163248 DOI: 10.1016/j.joca.2017.01.015] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2016] [Revised: 12/27/2016] [Accepted: 01/26/2017] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To investigate the longitudinal association between endogenous sex hormones and knee osteoarthritis (OA) structures and pain. METHOD We examined 200 participants (mean age 63.0 ± 7.3 years) from a clinical trial of vitamin D supplement for symptomatic knee OA. Serum levels of estradiol, progesterone, testosterone and sex hormone binding globulin (SHBG) were analyzed at baseline and 24 months later. Magnetic resonance imaging (MRI) scans of selected knee were obtained at both baseline and follow-up for the measurement of cartilage volume, cartilage defects, bone marrow lesions (BMLs) and effusion-synovitis volume. Knee pain was assessed using a 100 mm visual analogue scale (VAS). Longitudinal data were analyzed using linear mixed-effects model. RESULTS One hundred and seven males and 93 females were included in this study. For females, after adjustment for age, body mass index (BMI), and vitamin D level, progesterone was positively associated with cartilage volume (β = 0.12 mm3 per quartile, P < 0.01). Estradiol levels were associated with lower grades of BMLs (β = -0.46 per quartile, P = 0.03), while estradiol (β = -1.28 per quartile, P = 0.04), progesterone (β = -1.56 per quartile, P < 0.01) and testosterone (β = -1.51 per quartile, P = 0.01) were inversely associated with effusion-synovitis volume. Testosterone was inversely associated with knee pain. No consistent associations were observed for males. CONCLUSION In women but not men, low serum levels of endogenous estradiol, progesterone and testosterone are associated with increased knee effusion-synovitis and possibly other OA-related structural changes. This may contribute to observed sex differences in knee OA.

Abstract
OBJECTIVE To describe cross-sectional and longitudinal associations between magnetic resonance imaging (MRI)-detected osteophytes (OPs) and knee structural abnormalities and knee pain in older adults. METHOD A prospective population-based cohort study of 895 participants aged 50-80 years (mean age 62 years, 50% female) was performed. T1-or T2-weighted fat suppressed MRI was used to assess knee OPs, cartilage volume, cartilage defects and bone marrow lesions (BMLs) at baseline and after 2.6 years. Radiographically-detected OPs were scored according to the Osteoarthritis Research Society International (OARSI) atlas. Knee pain was assessed using a self-administered questionnaire at baseline, 2.6 and 5 years later. RESULTS 85% of participants had MRI-detected OPs at baseline, while 10% of participants had radiographically-detected OPs. Cross-sectionally, higher gardes of MRI-detected OPs in all compartments were significantly, independently and site-specifically associated with higher prevalences of cartilage defects and BMLs, lower cartilage volume and higher prevalence of knee pain. Longitudinally, higher gardes of baseline MRI-detected OPs site-specifically predicted greater risks of any increase in cartilage defects or BMLs, and loss of cartilage volume in medial and lateral tibiofemoral (LTF) and total compartments over 2.6 years in multivariable analyses. These significant associations were similar in those without radiographically-detected OPs. MTF and total OP scores were significantly associated with change in total knee pain over 2.6 and 5 years but these became non-significant after adjustment for cartilage defects and BMLs. CONCLUSION MRI-detected knee OPs are common and appear to be clinically relevant to knee structural changes in older adults.

Abstract
OBJECTIVE To describe cross-sectional and longitudinal associations between serum levels of interleukin (IL) - 6, IL-17A, IL-17F, IL-23 and knee bone marrow lesions (BMLs) in patients with knee osteoarthritis (OA). DESIGN Patients (n = 192) with symptomatic knee OA (mean 63 years, range 50-79, female 53%) were assessed at baseline and after 24 months. At each time point, serum IL-6, IL-17A, IL-17F and IL-23 were measured using Bio-Plex® Multiplex Immunoassays with Luminex xMAP technology. Knee BMLs were scored using the modified whole organ MRI score (WORMS) from T2 weighted fat-suppressed fast spin echo magnetic resonance imaging (MRI). Multivariable linear regression and log binominal regression were used to determine the associations between cytokines and BMLs. RESULTS Baseline IL-6 (quarters) were significantly associated with total knee BMLs (P < 0.01 for the trend) as well as associated with an increase in BML score (P = 0.05 for the trend), after adjustment for confounders. Baseline IL-17F and IL-23 (highest quarters vs others) was associated with an increase in BML score in females (P = 0.04 for IL-17F; P = 0.01 for IL-23), but not in males, in multivariable analyses. In contrast, IL-17A was not significantly associated with BMLs in either females or males. CONCLUSION IL-6 is associated with increased knee BMLs in both females and males with OA. Serum IL-17F and IL-23 predicted increased knee BML scores in females only, suggesting that inflammation is involved in BML pathogenesis in knee OA, especially in women.

Abstract
Test-retest reliability of the combined process of ultrasound imaging (USI) and image measurement of thickness of abdominal and upper lumbar multifidus (MF) muscles and MF cross sectional area (CSA) of older adults has not been established. Imaging muscles of older adults can be challenging due to age-related changes in the spine and skeletal muscle so establishing test-retest reliability in this population is important. This study aimed to evaluate test-retest reliability of USI of abdominal and MF muscle thickness and MF CSA for adults aged 50-79 years. One operator took single sets of ultrasound images of abdominal and MF muscles of 23 adults aged 50-79 years participating in a clinical trial of vitamin D supplementation for knee osteoarthritis, on two occasions, one week apart. Images were subsequently measured by a single examiner. Test-retest reliability for abdominal muscle thickness and MF CSA was substantial (intraclass correlation coefficients (ICC) > 0.81) and for MF thickness ranged from fair to substantial (ICC 0.55-0.86). The standard error of measurement (SEM) was low (0.02-0.21) in every case. ICCs were low and SEM values were high for percentage thickness change. The substantial test-retest reliability of abdominal and MF (L4-L5) muscle thickness and of MF CSA supports the use of USI as a clinical and research tool to assess abdominal and MF muscle thickness and MF CSA of older adults.

Abstract
OBJECTIVE Although being overweight or obese is an important risk factor for the development of knee osteoarthritis (OA), the interplay between weight and genetic factors remains unclear. This study aimed to examine the associations between weight and knee cartilage volume/defects over 10 years in offspring having at least one parent with a total knee replacement (TKR) for primary knee OA and in controls without a knee OA family history. METHOD 367 participants (183 offspring and 184 controls) aged from 26 to 61 years were recruited at baseline, and followed at 2 and 10 years later. T1-weighted magnetic resonance imaging (MRI) of the right knee was used to measure cartilage volume/defects at each time-point. Mixed-effects models were used with adjustment for potential confounders. RESULTS Study participants were middle-age adults (mean age 45 years, mean weight 77.5 kg at baseline). In multivariable analysis, increasing body weight was deleteriously associated with medial tibiofemoral cartilage volume (β = -0.28 ml, per 1 SD increase, 95% CI -0.49 to -0.07) and presence of medial tibiofemoral cartilage defects (RR = 1.27, per 1 SD increase, 95% CI 1.07 to 1.51) in offspring over 10 years. Similar associations were observed for lateral tibiofemoral cartilage volume (β = -0.19 ml, P = 0.059), and defects (RR = 1.24, P = 0.049). However, there were no statistically significant associations between weight and cartilage volume or defects in controls. CONCLUSION The adverse effects of increasing weight are stronger in the offspring of people with knee replacement for knee OA suggesting genetics-environment interaction with regard to overweight/obesity in the pathogenesis of knee OA particularly in the early stages.

Abstract
OBJECTIVE Endoplasmic reticulum (ER) stress plays an important role in ischemia-mediated cell death. The aim of the current study is to investigate the effects of salubrinal (Sal), a selective eIF2a dephosphorylation inhibitor, on heart failure rats and related mechanisms. METHODS Heart failure was induced by coronary artery ligation (MI) in adult male Sprague-Dawley rats. To ensure comparable MI sizes post coronary artery ligation on various groups, echocardiography examination was performed before and 30 minutes after ligation in MI groups. Then rats were randomly assigned to 4 groups: Sham group (n=12), MI group (n=10), MI plus vehicle injections group (DMSO group, n=12) and MI plus Sal injection group (Sal group, n=12). Sal (1 mg/kg) or DMSO was injected via the tail vein daily for the first 3 days (starting at 30 minutes after ligation of the left coronary artery), followed by subcutaneous injections twice per week for 8 weeks. Cardiac function was assessed by echocardiography and cell apoptosis assessed by flow cytometric analysis after 8 weeks. Protein and mRNA levels of ER stress markers were evaluated by immunohistochemistry and real time RT-PCR respectively. RESULTS Eight weeks later, LVEF was significantly higher, while LVESD and LVEDD values were significantly lower in Sal group compared to MI and DMSO groups (all P<0.05); LV/BW ratio was significantly higher in MI group than in Sham group ((2.30±0.40) mg/g vs.(1.78±0.31) mg/g, P<0.05), which was significantly reduced in Sal group ((1.88±0.25) mg/g), but not in DMSO group((2.25±0.36) mg/g, P<0.05 vs. MI). In addition, flow cytometric analysis showed that Sal treatment significantly reduced apoptosis but not necrosis in post MI. Immunohistochemistry and real time PCR analysis showed that the myocardial protein and mRNA expression of ER stress markers were significantly lower in Sal group than in MI group, myocardial caspase-12 expression was significantly upregulated in MI group and significantly reduced by Sal treatment. CONCLUSIONS Our results suggest that reduction of ER stress and myocardial apoptosis through inhibition of eIF2α dephosphorylation may serve as the potential mechanisms for the improved cardiac function and attenuated cardiac remodeling post Sal treatment in this heart failure rat model.

Abstract
AIMS The lower limit of exposure to cyclosporine A (CsA) has not yet been established in donation after cardiac death (DCD) renal transplantation recipients with delayed graft function (DGF) receiving enteric-coated mycophenolate sodium (EC-MPS) therapy. Stable and adequate mycophenolic acid (MPA) dosing may facilitate lower CsA exposure after DCD renal transplantation in recipients with DGF without compromising safety. METHODS A 12-month, single-centre open-label prospective trial was performed in our centre. According to their DGF risk index using the previous DGF prediction models, we divided up the patients on oral CsA into either a DGF group (n = 26) and no DGF group (n = 48). All of the patients initially received the standard EC-MPS dosing (1440 mg/day). The initial dose of CsA in the low risk of DGF group was 4.5 mg/kg/day and in the high risk of DGF group was 2.5 mg/kg/day. Efficacy parameters, safety and tolerability were assessed over a 12-month study period. RESULTS The incidence of DGF was 18.5% in the 162 DCD recipients. Between the DGF group and the no DGF group, the 1-year patient survival and graft survival were not significantly different. The incidence of BPAR was higher in the DGF group (26.9% vs. 8.3%, p = 0.032). Most patients in the DGF group had recovery of renal function after 1 month. The adverse events between the two groups were not significantly different. The daily EC-MPS doses of the DGF group were significantly higher than the no DGF group before the 6-month follow-up period. There were no significant differences between the two groups regarding the mean AUC levels during the follow-up period. CONCLUSIONS These results show that low expose CsA with standard dosing of EC-MPS and thymoglobulin was efficacious, safe and well-tolerated in DCD renal transplant recipients with DGF in China. Furthermore, stable and adequate MPA exposure helped to reduce the dose of and exposure to CsA. Thus, this may lead to less-induced nephrotoxicity and better renal function recovery.

Abstract
Objective: To analyze long-term mortality and patients characteristics of cardiac resynchronization therapy (CRT) for patients with chronic heart failure. Methods: In-patients with chronic heart failure who received CRT in the three medical centers(Bethune International Peace Hospital, General Hospital of Shenyang Military Command of Chinese People's Liberation Army, and 251 Hospital of People's Liberation Army)from March 2001 to June 2013 were included.Mortality and related causes, echocardiographic parameters were analyzed. Results: A total of 200 patients were treated with CRT therapy (154 males, mean age (60.57±11.75) years), 59 cases suffered from ischemic cardiomyopathy (ICM), patients were followed up from 0.5 to 12 years.The all-cause mortality rate was 25.50% (51/200), 20 out of 59 (33.90%) ICM patients died, as compared with 31 deaths out of 141 (21.98%) in non-ischemic cardiomyopath (NICM) patients.Thirty-six patients died due to cardiac death (70.59%), in which sudden death occurred in 21 patients (41.18%). Non-cardiac death occurred in 13 patients (25.49%), two patients died due to unknown reasons (3.92%). Incidence of cardiac death was significantly higher than non-cardiac death (P<0.01). The main cause for cardiac death was NICM (28/36, 77.78%), while the main cause of non-cardiac death was ICM (11/13, 84.62%, P<0.01). Patients died due to cardiac death were younger (P<0.01) and had larger left atrial end-diastolic diameter (LAEDD) and left ventricular end-diastolic diameter (LVEDD) (P<0.01), lower left ventricular ejection fraction (LVEF)(P<0.05), higher pulmonary artery pressure(P<0.05) compared to patients with non-cardiac death.One hundred and fifty-two cases received CRT-P and 48 cases received CRT-D, there were no significant differences in gender, the course of heart failure, serum creatinine levels, pre-operative and post-operative QRS duration and so on between the CRT-P and CRT-D groups(all P>0.05). Eleven out of the 48 cases with CRT-D died during the following-up (21.57%) , while 40 out of 152 cases with CRT-P died (78.43%) during the following-up(χ2=3.13, P<0.01). The proportional mortality rate in cause of death in patients with CRT-D was non-cardiac while in those with CRT-P was cardiac (χ2=2.66, P<0.01), sudden death rate was also significantly higher in CRT-P group than in CRT-D group (χ2=2.16, P<0.01). By using single- and multiple-factor Cox regression analysis, age, disease course, pre-operation QRS duration and NYHA classification were predictors of cardiac death(all P<0.05). Conclusions: The all-cause mortality of CRT is 25.50% in this patient cohort, mortality rate was higher in ICM patients than in NICM patients.Sudden cardiac death rate was the highest mortality reason.The mortality rate of patients with CRT-P was significantly higher than in patients with CRT-D.In comparison with patients of non-cardiac death, patients of cardiac death had larger left atrium and left ventricle and worse heart function before CRT implantation.

Abstract
PURPOSE To assess reliability and validity of a semi-automated quantitative method to measure infrapatellar fat pad (IPFP) signal intensity in patients with knee osteoarthritis (OA). METHODS Hundred patients with knee OA were selected. Sagittal planes of fat-saturated T2-weighted images obtained on 1.5-T magnetic resonance imaging (MRI) were utilized to assess IPFP signal intensity using MATLAB. Knee structural abnormalities including cartilage defects, bone marrow lesions (BML) and radiographic OA (ROA) were evaluated. Clinical construct validity and concurrent validity were examined through describing associations of IPFP measurements with knee structural abnormalities and a semi-quantitative scoring method, respectively. The reliability was examined by calculating the intra- and inter-observer correlation coefficients. RESULTS Significantly positive associations were found between standard deviation of IPFP signal intensity [sDev (IPFP)], clustering factor (H) and all knee structural abnormalities. The volume of high signal intensity regions [Volume (H)] and the ratio of Volume (H) to volume of whole IPFP [Percentage (H)] were positively associated with cartilage defects and ROA, but not with BMLs. The median value [Median (H)] and upper quartile value [UQ (H)] of high signal intensity were only significantly associated with quartiles of cartilage defect score. Significant correlations were found between all quantitative measurements and semi-quantitative scores (All P < 0.001). Intraclass and interclass correlation coefficients for these quantitative measures were high (>0.90). CONCLUSIONS A novel and efficient method to segment IPFP and calculate its signal intensity on T2-weighted MRI images is documented. This method is reproducible, and has concurrent and clinical construct validity, but its predictive validity needs to be examined by future longitudinal studies.

Abstract
We report the successful synthesis and characterization of a new type I-II-V bulk form diluted magnetic semiconductor (DMS) Li(Zn,Mn,Cu)As, in which charge and spin doping are decoupled via (Cu,Zn) and (Mn,Zn) substitution at the same Zn sites. Ferromagnetic transition temperature up to ∼33 K has been observed with a coercive field ∼40 Oe for the 12.5% doping level. μSR measurements confirmed that the magnetic volume fraction reaches nearly 100% at 2 K, and the mechanism responsible for the ferromagnetic interaction in this system is the same as other bulk form DMSs.

Abstract
UNLABELLED We assessed whether the vitamin D receptor gene polymorphisms (FokI, BsmI, ApaI, and TaqI) were associated with ankylosing spondylitis (AS) in a Chinese Han population. The TaqI polymorphism G allele was a risk factor in AS susceptibility. INTRODUCTION Previous studies have found that serum vitamin D levels are declined in patients with AS. The present study aims to evaluate the role of vitamin D receptor (VDR) gene polymorphisms in AS susceptibility in a Chinese Han population. METHODS Four single nucleotide polymorphisms (SNPs) in the VDR gene (FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232), and TaqI (rs731236)) were genotyped by the improved multiplex ligase detection reaction (iMLDR) method in 620 AS patients and 620 geographically and ethnically matched healthy controls. Haplotypes were constructed after linkage disequilibrium (LD) analysis. RESULTS Statistically significant difference was only found in the TaqI polymorphism between AS patients and controls. The TaqI polymorphism G allele was higher in AS group than that in controls (OR [95 % CI] = 1.624 [1.122-2.352], χ (2) = 6.705, P = 0.006). Linkage disequilibrium has been detected in TaqI and BsmI polymorphisms (D' = 0.87, r (2) = 0.70). Two novel haplotypes (H1: AC and H2: GT) were significantly associated with the risk of AS, and they play protective and risk roles in AS morbidity, respectively. CONCLUSIONS The VDR gene TaqI polymorphism G allele may be a risk factor in AS susceptibility.

Abstract
UNLABELLED As a paramyxovirus, Newcastle disease virus (NDV) has the ability to edit its P (phosphoprotein) gene to synthesize three kinds of viral protein (P, V and W). It is technically very difficult to differentiate P, V and W mRNAs, and little was known about NDV regulation of RNA-editing frequency. To investigate the rules of NDV RNA editing, the ratio of the P gene-derived transcripts (P, V and W) was determined by sequencing at different time points post-infection. The results showed unstable ratio of V and W mRNA at different time points, and the frequency of NDV editing was significantly increased at the early period of infection (P KEYWORDS Newcastle disease virus; phosphoprotein; RNA editing; G insertion.
