Abstract
The effect of pulsed electromagnetic field (PEMF) on bone healing is still uncertain and it has not been established as a standardized treatment. The aim of this systematic review and meta-analysis is to evaluate the effect of PEMF on bone healing in patients with fracture. We searched CNKI, Wan Fang, VIP, EMbase, PubMed, CENTRAL, Web of Science, Physiotherapy Evidence Database, and Open Grey websites for randomized controlled trials (published before July 2019 in English or Chinese) comparing any form of PEMF to sham. Reference lists were also searched. Related data were extracted by two investigators independently. The bias risk of the articles and the evidence strength of the outcomes were evaluated. Twenty-two studies were eligible and included in our analysis (n = 1,468 participants). The pooled results of 14 studies (n = 1,131 participants) demonstrated that healing rate in PEMF group was 79.7% (443/556), and that in the control group was 64.3% (370/575). PEMF increased healing rate (RR = 1.22; 95% confidence interval [CI] = 1.10-1.35; I2 = 48%) by the Mantel-Haenszel analysis, relieved pain (standardized mean difference (SMD) = -0.49; 95% CI = -0.88 to -0.10; I2 = 60%) by the inverse variance analysis, and accelerated healing time (SMD = -1.01; 95% CI = -2.01 to -0.00; I2 = 90%) by the inverse variance analysis. Moderate quality evidence suggested that PEMF increased healing rate and relieved pain of fracture, and very low-quality evidence showed that PEMF accelerated healing time. Larger and higher quality randomized controlled trials and pre-clinical studies of optimal frequency, amplitude, and duration parameters are needed. © 2020 Bioelectromagnetics Society.

Abstract
Background:Abnormal liver function can be seen in not only hepatitis B virus infection (HBV), hepatitis C virus infection (HCV), hepatic carcinoma (HCC), but also in primary biliary cirrhosis (PBC), autoimmune hepatitis (AIH), and systemic autoimmune rheumatic diseases (SARD). Antinuclear antibody (ANA) testing using indirect immunofluorescence assay (IIFA) is a common and economical method which contributes to detect SARD and autoimmune liver diseases [1].Objectives:Our objective was to investigate ANA positivity, titers and their patterns in multiple liver diseases, including PBC, AIH, HBV, HCV, and HCC, compared to healthy controls (HC).Methods:2537 patients with SARD, 137 PBC cases, 57 AIH cases, 3420 HBV cases, 769 HCV cases, 268 HCC cases, and 1073 HC were retrospectively assessed. The titers and patterns of ANA were detected with the IIFA method.Results:ANA positivity rate was considerably discernible between these diseases, which is 90.1% in SARD, 93.4% in PBC, 49.1% in AIH, 19.1% in HBV, 13.9% in HCV and 23.5% in HCC. Moreover, only 4.9% of HCC cases, 2.5% of HBV patients and 1.6% of HCV patients had an ANA titer ≥ 1:320. The mixed pattern which composed of at least two patterns majorly lied in PBC. AC-15 and AC-21 was frequently related to liver diseases; the former pattern was more frequently found in AIH (84.2%) and PBC (8.8%), and the latter pattern was easily seen in PBC (62.2%) and HCC (22.6%). The positive rate of ANA in HC was 12.2% and its major pattern was AC-2.Conclusion:There are differences in ANA positivity among patients with SARD and various liver diseases. Some mixed patterns may provide important evidence for the diagnosis of PBC. Clinicians should pay attention to ANA patterns and titer during the interpretation of this test.References:[1]Damoiseaux J, Andrade L, Carballo OG, Conrad K, Francescantonio P, Fritzler MJ, Garcia DLTI, Herold M, Klotz W, Cruvinel WM, Mimori T, von Muhlen C, Satoh M, Chan EK, (2019) Clinical relevance of HEp-2 indirect immunofluorescent patterns: the International Consensus on ANA patterns (ICAP) perspective.

Abstract
Background:Systemic lupus erythematosus (SLE) and Sjögren’s syndrome (SS) are systemic autoimmune diseases characterized by a broad spectrum of clinical manifestations and disease course. Alternative therapies such as therapeutic plasma exchange (TPE), immunoadsorption are recommended to the patients who lack a good response to standard therapy [1].Objectives:Our observational study was to explored whether abnormalities in T-cells, B-cells and their subtypes were present in the patients who had TPE or immunoadsorption in patients with SLE and SS compared with healthy controls (HC).Methods:Demographic, clinical variables and autoantibodies were recorded. Flow cytometry was used to establish the frequencies of lineage subsets. Monoclonal antibodies against 21 surface markers such as CD3, CD4, CD8, were used to distinguish and evaluate T-cells’ and B-cells’ subpopulation. SLE acvity was measured using systemic lupus erythematosus disease activity index (SLEDAI). Comparisons between subgroups were undertaken using paired T-test, Mann-Whitney U test and ANOVA.Figure 1.Altered expression of CD4+ T-cell subsets in the patients with SLE and SS after treated with plasma exchange or immunoadsorptionResults:6 SS patients and 1 SLE patient underwent immune adsorption, while the other 5 SLE patients had plasma exchange all for three times. There was no significant difference among SLE, SS and HC in the proportion of T-cells and B-cells. The proportion of CD3-CD19+CD27+IgD+ B-cells were reduced in SLE, while CD3+CD4+CD25+CD127- T-cells were elevated in SS. The proportion of CD3+CD4+CD45RA+CCR7+T-cells were increased (p= 0.045), while CD3+CD4+CD25+CD127- T-cells were declined (p= 0.027) and CD3+CD4+CXCR5+PD-1+ T-cells went down after the therapies (p≤ 0.030). The proportion of CD3-CD19+IgD-IgM-CD27+CD38+ B-cells was also reduced after TPE or immunoadsorption (p= 0.032) with ANA titers and IgG decreasing dramatically. SLEDAI scores were reduced after the therapy in SLE patients.Conclusion:The T-cell and B-cell’s profiles were proved to have alteration after TPE or immunoadsorption which shed light on the complicated mechanisms of these relatively novel therapy in SLE and SS.References:[1]Bertsias GK, Tektonidou M, Amoura Z, et al.

Abstract
Background:Poorer work productivity due to pain and functional impairment is commonly seen in ankylosing spondylitis (AS) patients, which may contribute to huge social economic burden. However, data about work outcomes and associated factors in Chinese AS patients were barely reported.Objectives:To assess work outcomes and identify factors associated with poor work productivity in patients with AS in China.Methods:A cross-sectional study was conducted in China. Adult patients (aged ≥ 18 years) fulfilled the 1984 New York modified criteria of AS were enrolled from rheumatology center from Jan 2017 to Aug 2017. All participants completed questionnaires about socio-demographic characteristics, disease characteristics, quality of life and the Work productivity and activity impairment questionnaire in AS (WPAI:SpA) to accesses the impact of chronic health conditions on job performance and productivity. Factors associated with work outcomes were evaluated.Results:A total of 91 patients with AS were included: 87.8% males, 78.02% employed, mean age and disease duration of 30 and 10 years respectively. The mean (SD) activity impairment of all patients was 48.57% (22.02%). For patients with employed work, mean (SD) absenteeism, presenteeism and work productivity loss were 10.22% (19.44%), 43.86% (22.48%) and 47.92% (25.81%) respectively. In multivariable analysis, activity impairment was associated with Bath Ankylosing Spondylitis Functional Index (BASFI) (P<0.01) and Ankylosing Spondylitis Quality of Life (ASQoL) (P<0.01). Absenteeism was associated with disease duration (P=0.03). Presenteeism was associated with disease duration (P=0.04), BASFI (P<0.01) and ASQoL (P<0.01). Work productivity loss was associated with BASFI (P<0.01) and ASQoL (P<0.01).Conclusion:Longer disease duration, reduced physical function and poorer quality of life are associated with reduced work productivity in Chinese AS patients.References:[1]Boonen A, van der Heijde D, Landewe R, Spoorenberg A, Schouten H, Rutten-van Molken M, et al.

Abstract
Background:Studies into ankylosing spondylitis (AS) and its relationship with immune function are controversial, and the correlation between the efficacy of TNF-α inhibitor and changes in immune function is unclear.Objectives:We conducted a prospective study of T-cell and B-cell subset distribution and analyzed lymphocyte function in AS patients to further clarify changes to the immune system caused by AS and to explore resistance that could contribute to relapse after treatment.Methods:A total of 40 immune cells were tested with flow cytometry, and the results of 105 HC (healthy control) subjects, 177 active-stage AS patients, and 23 AS cases before and after 12 weeks of Anbainuo therapy were analyzed.Results:Compared with the HC group, the proportion of immune cells, such as naïve and central memory CD4+T cells, in AS increased (p<0.0001), but effector memory and terminally differentiated CD4+T cells were decreased (p<0.01 and 0.0001, respectively). Naïve, central memory, and effector memory CD8+T cells were increased (p<0.0001, 0.001, and 0.01, respectively), but terminally differentiated CD8+T cells were decreased (p<0.0001). Th1 cells (helper T cells-1), Tfh1 cells (follicular helper T cells-1), Tc1 cells (cytotoxic T cells-1), and Tregs (regulatory T cells) were lower (p<0.01, 0.05, 0.0001, and 0.001, respectively), but Th17 cells, Tfh17 cells, and Tc cells were higher (p<0.001, 0.0001 and 0.001, respectively). The proportions of total B cells and class-switched B cells were increased (p<0.05), but non-switched B cells, plasma cells, memory B cells, and immature Bregs (regulatory B cells) were lower (p<0.01, 0.0001, 0.0001, and 0.0001, respectively). After Anbainuo therapy, the percentage of Tregs and B10 cells (IL-10-producing regulatory B cells) had increased (p<0.01and 0.05, respectively), and the increase in Tregs was positively correlated with the decrease in CRP (C-reactive protein) (r= 0.489, p=0.018).Conclusion:We found that, in terms of both innate and acquired immunity, active-stage AS patients have an immunity imbalance involving multiple types of immune cells, including CD4+T cells, CD8+T cells, Th cells, Tfh cells, Tc cells, Tregs, Bregs, and B cells. Anbainuo can not only help to inhibit disease activity and partial immune function imbalance in AS but can also increase the number of negative regulatory cells in inflammation.References:[1]Long, S., et al., High frequency of circulating follicular helper T cells is correlated with B cell subtypes in patients with ankylosing spondylitis.

Abstract
BACKGROUND Folate metabolism plays an important role in DNA methylation and nucleic acid synthesis and thus may function as a regulatory factor in cancer development. Genome-wide association studies (GWASs) have identified some single-nucleotide polymorphisms (SNPs) associated with cutaneous melanoma-specific survival (CMSS), but no SNPs were found in genes involved in the folate metabolic pathway. OBJECTIVES To examine associations between SNPs in folate metabolic pathway genes and CMSS. METHODS We comprehensively evaluated 2645 (422 genotyped and 2223 imputed) common SNPs in folate metabolic pathway genes from a published GWAS of 858 patients from The University of Texas MD Anderson Cancer Center and performed the validation in another GWAS of 409 patients from the Nurses' Health Study and Health Professionals Follow-up Study, in which 95/858 (11·1%) and 48/409 (11·7%) patients died of cutaneous melanoma, respectively. RESULTS We identified two independent SNPs (MTHFD1 rs1950902 G>A and ALPL rs10917006 C>T) to be associated with CMSS in both datasets, and their meta-analysis yielded an allelic hazards ratio of 1·75 (95% confidence interval 1·32-2·32, P = 9·96 × 10-5 ) and 2·05 (1·39-3·01, P = 2·84 × 10-4 ), respectively. The genotype-phenotype correlation analyses provided additional support for the biological plausibility of these two variants' roles in tumour progression, suggesting that variation in SNP-related mRNA expression levels is likely to be the mechanism underlying the observed associations with CMSS. CONCLUSIONS Two possibly functional genetic variants, MTHFD1 rs1950902 and ALPL rs10917006, were likely to be independently or jointly associated with CMSS, which may add to personalized treatment in the future, once further validated. What is already known about this topic? Existing data show that survival rates vary among patients with melanoma with similar clinical characteristics; therefore, it is necessary to identify additional complementary biomarkers for melanoma-specific prognosis. A hypothesis-driven approach, by pooling the effects of single-nucleotide polymorphisms (SNPs) in a specific biological pathway as genetic risk scores, may provide a prognostic utility, and genetic variants of genes in folate metabolism have been reported to be associated with cancer risk. What does this study add? Two genetic variants in the folate metabolic pathway genes, MTHFD1 rs1950902 and ALPL rs10917006, are significantly associated with cutaneous melanoma-specific survival (CMSS). What is the translational message? The identification of genetic variants will make a risk-prediction model possible for CMSS. The SNPs in the folate metabolic pathway genes, once validated in larger studies, may be useful in the personalized management and treatment of patients with cutaneous melanoma.

Abstract
BACKGROUND The effectiveness of trunk restraint on post-stroke arm motor function and daily function remain controversial. OBJECTIVE To evaluate the effect of adding trunk restraint to task-oriented rehabilitation of arm motor function and functional ability after stroke. METHODS Nine databases were systematically searched for randomized controlled trials studying the effects of trunk restraint in post-stroke task-oriented training. Researchers assessed methodological qualities using the Physiotherapy Evidence Database scale, and extracted data related to study participants, intervention, and outcomes. The overall effectiveness was calculated using a meta-analytic method. RESULTS In total, ten articles met the inclusion criteria and nine trails (n = 255 subjects) were included in quantitative analyses. Meta-analysis revealed that trunk restraint exhibited a significant improvement on the Motor Activity Log-amount of use, 0.39 (95% CI: 0.25- 0.54), the Motor Activity Log-quality of movement, 0.45 (95% CI: 0.27- 0.63), the Fugl-Meyer Assessment (upper extremity), 1.09 (95% CI: 0.67- 1.51), Action Research Arm test, 4.51 (95% CI: 2.49- 6.54) and performance of Activities of daily living, 1.70 (95% CI: 0.19- 3.21) in trunk restraint group in patients at subacute stage, compared to the non-trunk restraint group, but no significant difference was found in patients with chronic stroke. CONCLUSIONS Adding trunk restraint to task-oriented training may improve function in patients with subacute stroke.

Abstract
BACKGROUND Previous studies have shown that pulsed electromagnetic fields (PEMF) stimulate angiogenesis and may be a potential treatment strategy to improve cardiac function after myocardial infarction (MI). This study explored the effects and its related mechanisms of PEMF in MI mice.Methods and Results:MI mice were used in PEMF treatment (15 Hz 1.5 mT PEMF or 30 Hz 3.0 mT PEMF) for 45 min per day for 2 weeks. Furthermore, an in vivo Matrigel plug assay was used to observe the effect of PEMF in promoting angiogenesis. Compared with the sham PEMF group, PEMF treatment with 30 Hz 3.0 mT significantly improved heart function. PEMF treatment with 15 Hz 1.5 mT and 30 Hz 3.0 mT both increased capillary density, decreased infarction area size, increased the protein expression of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 2 (VEGFR2), Ser473-phosphorylated Akt (pSer473-Akt) and S1177-phosphorylated endothelial nitric oxide synthase (pS1177-eNOS), and increased the mRNA level of VEGF and hypoxia inducible factor 1-alpha (HIF-1α) in the infarct border zone. Additionally, treatment with 30 Hz 3.0 mT also increased protein and mRNA level of fibroblast growth factor 2 (FGF2), and protein level of β1 integrin, and shows a stronger therapeutic effect. CONCLUSIONS PEMF treatment could promote angiogenesis of the infarct border zone and improve cardiac function in MI mice. A treatment parameter of 30 Hz 3.0 mT is remarkably effective in MI mice. The effect is associated with the proangiogenic signaling pathways of HIF-1α/VEGF/Akt/eNOS or HIF-1α/FGF2/Akt/eNOS.

Abstract
OBJECTIVE Long noncoding RNAs (lncRNAs) play important roles in the pathogenesis of bladder cancer. A recent study reported that lncRNA HNF1A-AS1 (HNF1A-AS1) was upregulated in urothelial carcinoma of the bladder (UCB) and served as a tumor promoter. However, the clinical significance of HNF1A-AS1 in the prognosis of patients with UCB was poorly understood. This work was designed to investigate the relationship between HNF1A-AS1 expression level and the prognosis of UCB. PATIENTS AND METHODS Relative expression levels of HNF1A-AS1 in UCB tissues were determined by qRT-PCR. Then, the associations between HNF1A-AS1 expression and clinical pathological parameters were further evaluated. Survival and Cox proportional-hazards regression analyses were performed to determine the correlation between HNF1A-AS1 expression levels and prognosis in the patients. RESULTS Data showed that the majority of UCB tissues showed higher HNF1A-AS1 levels than the corresponding normal tissues controls (p < 0.01). Statistical assay revealed that high HNF1A-AS1 expression was significantly correlated with histological grade (p = 0.008), tumor stage T (p = 0.003) and lymph nodes metastasis (p = 0.007). In addition, the overall survival time of patients with high HNF1A-AS1 expression was significantly shorter compared to those with low HNF1A-AS1 expression. Furthermore, multivariate analysis confirmed that relative HNF1A-AS1 expression was an independent predictor of overall survival in patients with UCB. CONCLUSIONS HNF1A-AS1 expression was upregulated in UCB, and it may be a useful prognostic biomarker for patients with UCB.

Abstract
PURPOSE To evaluate the efficacy of water therapy for disease activity, functional capacity, spinal mobility, and pain in patients with ankylosing spondylitis. METHODS PubMed, Ovid, web of science, Cochrane library, Physiotherapy Evidence Database, CNKI, VIP, Wan Fang, and Open Grey were searched for randomized controlled trials that investigated the effects of water therapy on patients with ankylosing spondylitis. Two researchers independently screened the literature databases and then assessed methodological qualities using the Physiotherapy Evidence Database scale and extracted data. Outcomes included were disease activity, functional capacity, spinal mobility, and pain. RESULTS A total of eight studies (n = 383) met the inclusion criteria. Analysis demonstrated that water therapy had a significant effect on disease activity and pain, but not on spinal mobility, or functional capacity in patients with ankylosing spondylitis. CONCLUSION Water therapy can benefit patients with ankylosing spondylitis by reducing disease activity and alleviating pain. More well-designed randomized controlled trials are needed to confirm the results.IMPLICATIONS FOR REHABILITATIONWater therapy can reduce disease activity and pain in patients with ankylosing spondylitis, but cannot improve functional capacity or spinal mobility.Due to its analgesic effect both during and after treatment, water therapy remains an alternative for patients with ankylosing spondylitis when land-based therapy is not well tolerated.

Abstract
Objective: To explore the prognostic value of the international prognostic index (IPI), the national comprehensive cancer network IPI(NCCN-IPI)and the age-adjusted IPI (aa-IPI) in diffuse large B cell lymphoma. Methods: A total of 311 patients with de novo diffuse large B-cell lymphoma (DLBCL) diagnosed from 2003 to 2012 in Nanfang hospital were included. All patients were divided into CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) and R-CHOP (rituximab, CHOP) groups. Survival analysis was compared among IPI, NCCN-IPI and aa-IPI models. Discrimination of three different prognostic models was assessed using the Harrell's C statistic. Results: A total of 311 patients were analyzed. Among them, 128 patients were treated with CHOP regimen and other 183 patients were treated with R-CHOP regimen. In CHOP groups, both NCCN-IPI (5-year OS: 59.7% vs 26.8%, P<0.001) and aa-IPI (5-year OS: 71.0% vs 25.0%, P<0.001) showed better risk stratification for low-intermediate and high-intermediate group than the IPI (5-year OS: 47.6% vs 36.6%, P=0.003). However, in the patients treated with R-CHOP, NCCN-IPI showed better risk stratification in low, low-intermediate, high-intermediate groups (5-year OS: 96.0% vs 83.0% vs 66.5%, P=0.009). According to the Harrell's C statistic, C-index of IPI, NCCN-IPI and aa-IPI for overall survival (OS) were 0.546, 0.667, 0.698 in CHOP group and 0.611,0.654, 0.695 in R-CHOP group respectively. In patients younger than 60 years old, C-index of IPI, NCCN-IPI and aa-IPI for OS were 0.534, 0.675, 0.698 in CHOP group and 0.584, 0.648, 0.695 in R-CHOP respectively. Conclusion: The NCCN-IPI is more powerful than IPI and aa-IPI in DLBCL patients receiving R-CHOP. aa-IPI is a preferable model in predicting prognosis than IPI and NCCN-IPI in anthracycline-based chemotherapy without rituximab.

Abstract
Objective: To clarify the characteristics of the A20 regulatory changes by analyzing mutations in the non-coding region of the A20 gene in patients with T-cell lymphoma leukemia (T-LCL) . Methods: PCR and nucleotide sequence analysis were used to detect mutations in the non-coding region of the A20 gene, and DNA samples from PBMCs of 52 cases of T-LCL and 99 healthy controls. Results: A missense mutation (c.-672T>G) was detected in the A20 gene promoter from one T-LCL patient, which has been registered as a SNP (rs139054966) in gene bank. Meanwhile, a new mutation was detected in the 3' UTR mRNA (3916 (C>G) ) . These two mutations were absent in other T-LCL samples and controls. Conclusion: The rs139054966 (c.-672T>G) and 3916 (C>G) mutations in the A20 gene were detected in T-LCL patients for the first time. There was also rs139054966 located on the binding region of the transcription factor P53, and its significance remained to be further clarified.

Abstract
One of the most important issues related to adiabatic shear failure is the correlation among temperature elevation, adiabatic shear band (ASB) formation and the loss of load capacity of the material. Our experimental results show direct evidence that ASB forms several microseconds after stress collapse and temperature rise reaches its maximum about 30 μs after ASB formation. This observation indicates that temperature rise cannot be the cause of ASB. Rather, it might be the result of adiabatic shear localization. As such, the traditional well-accepted thermal-softening mechanism of ASB needs to be reconsidered.

Abstract
Recent advancements in bioanalytical techniques have led to the development of novel and robust diagnostic approaches that hold promise for providing optimal patient treatment, guiding prevention programs and widening the scope of personalized medicine. However, these advanced diagnostic techniques are still complex, expensive and limited to centralized healthcare facilities or research laboratories. This significantly hinders the use of evidence-based diagnostics for resource-limited settings and the primary care, thus creating a gap between healthcare providers and patients, leaving these populations without access to precision and quality medicine. Smartphone-based imaging and sensing platforms are emerging as promising alternatives for bridging this gap and decentralizing diagnostic tests offering practical features such as portability, cost-effectiveness and connectivity. Moreover, towards simplifying and automating bioanalytical techniques, biosensors and lab-on-a-chip technologies have become essential to interface and integrate these assays, bringing together the high precision and sensitivity of diagnostic techniques with the connectivity and computational power of smartphones. Here, we provide an overview of the emerging field of clinical smartphone diagnostics and its contributing technologies, as well as their wide range of areas of application, which span from haematology to digital pathology and rapid infectious disease diagnostics.

Abstract
Enhanced detoxification is one of the important mechanisms for insecticide resistance. Most research in this field to date has focused on the role of cytochrome P450s. Our previous work revealed that flavin-dependent monooxygenases (FMOs) were involved in metabolic resistance of Spodoptera exigua. In the present study we investigated the molecular characteristics, expression patterns and oxidative activities of SeFMO on insecticides. Three FMO genes, which encode proteins with the typical FMO motifs, were cloned from S. exigua. The oxidative activities of eukaryotically expressed SeFMO enzymes were verified with the model substrate of FMO. Importantly, the SeFMOs had significantly higher oxidative activities on metaflumizone and lambda-cyhalothrin than on model substrates and other insecticides tested. The three SeFMOs were mainly expressed in the midgut, fat body and Malpighian tubules. The tissues responsible for xenobiotic metabolism and their expression characteristics were similar to those of P450s acting as detoxification genes. The study also revealed that the expression of SeFMOs could be induced by insecticide exposure, and that SeFMOs were over-expressed in a metaflumizone-resistant strain of S. exigua. These results suggest that SeFMOs are important insecticide detoxifying enzymes, and that over-expression of FMO genes may be one of the mechanisms for metabolic resistance in S. exigua.

Abstract
Recent studies indicate that circular RNA (circRNA) is involved in tumorigenesis, but its role in triple-negative breast cancer (TNBC) remains largely unknown. In this study, we characterized the role of circ-ITCH in TNBC and found that circ-ITCH was significantly down-regulated in TNBC tissues and cell lines and closely associated with poor prognosis. We therefore constructed the MDA-MB-231 and BT-549 TNBC cell lines stably expressing circ-ITCH by lentiviral vectors to determine its underlying mechanisms in TNBC progression. Most importantly, over-expression of circ-ITCH remarkably inhibited TNBC proliferation, invasion and metastasis both in vitro and in vivo. Mechanistically, we found that circ-ITCH acts as a sponge for miR-214 and miR-17 to increase expression of its ITCH linear isoform, thereby inactivating Wnt/β-catenin signaling. Our combined results show for the first time that circ-ITCH is a tumor suppressor, a promising prognostic biomarker in TNBC and that its restoration could well be a successful strategy in TNBC.

Abstract
Swine wastewaters with high levels of organic pollutants and antibiotics have become serious environmental concerns. Anaerobic technology is a feasible option for swine wastewater treatment due to its advantage in low costs and bioenergy production. However, antibiotics in swine wastewater have problematic effects on micro-organisms, and the stability and performance of anaerobic processes. Thus, this paper critically reviews impacts of antibiotics on pH, COD removal efficiencies, biogas and methane productions as well as the accumulation of volatile fatty acids (VFAs) in the anaerobic processes. Meanwhile, impacts on the structure of bacteria and methanogens in anaerobic processes are also discussed comprehensively. Furthermore, to better understand the effect of antibiotics on anaerobic processes, detailed information about antimicrobial mechanisms of antibiotics and microbial functions in anaerobic processes is also summarized. Future research on deeper knowledge of the effect of antibiotics on anaerobic processes are suggested to reduce their adverse environmental impacts.

Abstract
PURPOSE To determine the association between serum periostin and the presence of diabetic retinopathy (DR). METHODS Serum periostin was detected in 114 healthy subjects, 122 patients with type 2 diabetes mellitus (T2DM) and 159 patients with DR and compared among groups. Clinical data and other laboratory measurements such as glycated hemoglobin (HbA1c), lipid profiles, serum creatinine (Cr) and high-sensitivity CRP (hsCRP) were also collected and compared among groups. For subgroup analysis, patients with DR were divided into a non-proliferated diabetic retinopathy (NPDR) group and a proliferated diabetic retinopathy (PDR) group. Multivariate analysis was performed using logistic regression models. RESULTS The serum periostin level was significantly higher in patients with diabetic retinopathy compared with healthy subjects and patients with T2DM (both P < 0.001, respectively). Also, the periostin level was significantly higher in the PDR group compared to the NPDR group (P = 0.044). Multivariate logistic regression revealed that serum periostin was independently associated with the presence of DR in patients with T2DM (P < 0.001). The receiver operating characteristic (ROC) curves for DR development using serum periostin showed that the area under the receiver operating characteristic curves (AUC) was 0.838 (P < 0.001). CONCLUSIONS The current study demonstrated that serum periostin is significantly associated with the presence of DR in patients with T2DM and is an independent risk factor of DR.

Abstract
Purpose: The purpose of this study is to evaluate the effects of rehabilitation exercise on coronary artery of the patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).Methods: We searched Medline, EMBASE, Cochrane CENTRAL databases, ISI Web of Science databases, Chinese Biological Medicine Data Base, Chinese knowledge resources, and Wan Fang database. Two researchers independently screened the literature databases, and assessed methodological qualities using the Physiotherapy Evidence Database scale and extracted data.Results: The coronary restenosis rate in rehabilitation exercise group was 10.8% (23/212), and that in the control group was 21% (48/229). Patients with rehabilitation exercise showed a significant reduction in restenosis rate, compared to the control group ((pooled OR: 0.46, 95% CI: 0.26-0.82, p < 0.01); heterogeneity: Chi2=3.86, df =5 (p = 0.57); I2=0%). In addition, the late luminal loss per stent in the rehabilitation exercise group was significantly smaller than that in the control group ((pooled MD: -0.33, 95% CI: -0.52 to -0.13, p < 0.01); heterogeneity: Chi2=0.27, df =1 (p = 0.60); I2=0%).Conclusions: Appropriate rehabilitation exercise reduces the incidence of coronary restenosis after PCI in patients with CHD and contributes to a significant reduction in late luminal loss in the stented coronary segment.Implications for RehabilitationAppropriate rehabilitation exercise can reduce the incidence of coronary restenosis after percutaneous coronary intervention in patients with coronary heart disease.Appropriate rehabilitation exercise contributes to a reduction in late luminal loss in the stented coronary segment.

Abstract
Osteoarthritis (OA) significantly influences the quality life of people around the world. It is urgent to find an effective way to understand the genetic etiology of OA. We used weighted gene coexpression network analysis (WGCNA) to explore the key genes involved in the subchondral bone pathological process of OA. Fifty gene expression profiles of GSE51588 were downloaded from the Gene Expression Omnibus database. The OA-associated genes and gene ontologies were acquired from JuniorDoc. Weighted gene coexpression network analysis was used to find disease-related networks based on 21756 gene expression correlation coefficients, hub-genes with the highest connectivity in each module were selected, and the correlation between module eigengene and clinical traits was calculated. The genes in the traits-related gene coexpression modules were subject to functional annotation and pathway enrichment analysis using ClusterProfiler. A total of 73 gene modules were identified, of which, 12 modules were found with high connectivity with clinical traits. Five modules were found with enriched OA-associated genes. Moreover, 310 OA-associated genes were found, and 34 of them were among hub-genes in each module. Consequently, enrichment results indicated some key metabolic pathways, such as extracellular matrix (ECM)-receptor interaction (hsa04512), focal adhesion (hsa04510), the phosphatidylinositol 3'-kinase (PI3K)-Akt signaling pathway (PI3K-AKT) (hsa04151), transforming growth factor beta pathway, and Wnt pathway. We intended to identify some core genes, collagen (COL)6A3, COL6A1, ITGA11, BAMBI, and HCK, which could influence downstream signaling pathways once they were activated. In this study, we identified important genes within key coexpression modules, which associate with a pathological process of subchondral bone in OA. Functional analysis results could provide important information to understand the mechanism of OA.

Abstract
Objective: To explore the reference intervals of thyrotropin (TSH) and free thyroxine (FT(4)) in normal pregnant women. Methods: Prospective and longitudinal sequential collection of the cases were performed. A total of 155 singleton pregnant women who had regular prenatal examination and delivery in West China Second Hospital of Sichuan University from January 2015 to December 2015 were included as the research group. Blood samples were sequentially collected from the pregnant women at the first (9-13(+6) weeks) , the second (24-27(+6) weeks) , the third (32-36 weeks) trimesters, respectively. Another 155 non-pregnant women were selected as the control group simultaneously, in an effort to establish a range of reference intervals of thyroid index in each period of pregnancy. Meanwhile, neonatal plantar blood were also collected on special filter paper and TSH levels were measured. Results: (1) TSH reference intervals [percentile 2.5-percentile 97.5 (P(2.5)-P(97.5)) ] were 0.08-3.29 mU/L, 0.59-4.22 mU/L and 0.81-4.33 mU/L in three trimesters respectively. FT(4) reference intervals were 11.88-20.06 pmol/L, 9.89-15.80 pmol/L and 9.22-15.77 pmol/L in three trimesters respectively. (2) The median serum TSH in the first trimester (1.35 mU/L) was lower than that in the second trimester (2.15 mU/L) , the third trimester (2.19 mU/L) , and the control group (2.19 mU/L) . The differences were all statistically significant (P<0.05) . There was no significant difference in median serum TSH between the second trimester and the third trimester, the second trimester and the control group, and the third trimester versus the control group. (3) The median serum FT(4) in the first trimester (15.16 pmol/L) was higher than that in the second trimester (12.39 pmol/L) and the third trimester (12.26 pmol/L) . The differences were both statistically significant (P<0.05) . The median FT(4) in the second trimester and the third trimester was lower than that in the control group (15.64 pmol/L) , and the differences were both statistically significant (P<0.05) . (4) In the first trimester, the median serum total triiodothyronine (TT(3)) level (2.32 nmol/L) was higher than that in the control group (1.56 nmol/L) , total thyroxine (TT(4)) level (154.60 nmol/L) was also higher than that in the control group (98.25 nmol/L) , and free triiodothyronine (FT(3)) level (4.70 pmol/L) was lower than that in the control group (4.84 pmol/L) , the differences were all statistically significant (P<0.05) . (5) The TSH levels of all neonatus were normal [ (2.1±1.3) mU/L]. Conclusions: The thyroid hormone levels between pregnant women and non-pregnant women are significantly different. Moreover, the reference intervals are vary with pregnancy period. It is important to establish the specific reference intervals of thyroid hormones in the first, second and third trimester of pregnancy specific to local region or unit.

Abstract
Background Distant metastasis accounts for 90% of deaths from colorectal cancer (CRC). Genomic heterogeneity has been reported in various solid malignancies, but remains largely under-explored in metastatic CRC tumors, especially in primary to metastatic tumor evolution. Patients and methods We conducted high-depth whole-exome sequencing in multiple regions of matched primary and metastatic CRC tumors. Using a total of 28 tumor, normal, and lymph node tissues, we analyzed inter- and intra-individual heterogeneity, inferred the tumor subclonal architectures, and depicted the subclonal evolutionary routes from primary to metastatic tumors. Results CRC has significant inter-individual but relatively limited intra-individual heterogeneity. Genomic landscapes were more similar within primary, metastatic, or lymph node tumors than across these types. Metastatic tumors exhibited less intratumor heterogeneity than primary tumors, indicating that single-region sequencing may be adequate to identify important metastasis mutations to guide treatment. Remarkably, all metastatic tumors inherited multiple genetically distinct subclones from primary tumors, supporting a possible polyclonal seeding mechanism for metastasis. Analysis of one patient with the trio samples of primary, metastatic, and lymph node tumors supported a mechanism of synchronous parallel dissemination from the primary to metastatic tumors that was not mediated through lymph nodes. Conclusions In CRC, metastatic tumors have different but less heterogeneous genomic landscapes than primary tumors. It is possible that CRC metastasis is, at least partly, mediated through a polyclonal seeding mechanism. These findings demonstrated the rationale and feasibility for identifying and targeting primary tumor-derived metastasis-potent subclones for the prediction, prevention, and treatment of CRC metastasis.

Abstract
OBJECTIVE Long-term care (LTC), residential care requiring 24-hour nursing services, plays an important role in the health care service delivery system. The purpose of this study was to identify the needed clinical information and information flow to support LTC Registered Nurses (RNs) in care collaboration and clinical decision making. METHODS This descriptive qualitative study combines direct observations and semistructured interviews, conducted at Alberta's LTC facilities between May 2014 and August 2015. The constant comparative method (CCM) of joint coding was used for data analysis. RESULTS Nine RNs from six LTC facilities participated in the study. The RN practice environment includes two essential RN information management aspects: information resources and information spaces. Ten commonly used information resources by RNs included: (1) RN-personal notes; (2) facility-specific templates/forms; (3) nursing processes/tasks; (4) paper-based resident profile; (5) daily care plans; (6) RN-notebooks; (7) medication administration records (MARs); (8) reporting software application (RAI-MDS); (9) people (care providers); and (10) references (i.e., books). Nurses used a combination of shared information spaces, such as the Nurses Station or RN-notebook, and personal information spaces, such as personal notebooks or "sticky" notes. Four essential RN information management functions were identified: collection, classification, storage, and distribution. Six sets of information were necessary to perform RN care tasks and communication, including: (1) admission, discharge, and transfer (ADT); (2) assessment; (3) care plan; (4) intervention (with two subsets: medication and care procedure); (5) report; and (6) reference. Based on the RN information management system requirements, a graphic information flow model was constructed. CONCLUSION This baseline study identified key components of a current LTC nursing information management system. The information flow model may assist health information technology (HIT) developers to consolidate the design of HIT solutions for LTC, and serve as a communication tool between nurses and information technology (IT) staff to refine requirements and support further LTC HIT research.

Abstract
Summary
Objectives:
In this paper, we present a unified electrodynamic heart model that permits simulations of the body surface potentials generated by the heart in motion. The inclusion of motion in the heart model significantly improves the accuracy of the simulated body surface potentials and therefore also the 12-lead ECG.
Methods:
The key step is to construct an electromechanical heart model. The cardiac excitation propagation is simulated by an electrical heart model, and the resulting cardiac active forces are used to calculate the ventricular wall motion based on a mechanical model. The source-field point relative position changes during heart systole and diastole. These can be obtained, and then used to calculate body surface ECG based on the electrical heart-torso model.
Results:
An electromechanical biventricular heart model is constructed and a standard 12-lead ECG is simulated. Compared with a simulated ECG based on the static electrical heart model, the simulated ECG based on the dynamic heart model is more accordant with a clinically recorded ECG, especially for the ST segment and T wave of a V1-V6 lead ECG. For slight-degree myocardial ischemia ECG simulation, the ST segment and T wave changes can be observed from the simulated ECG based on a dynamic heart model, while the ST segment and T wave of simulated ECG based on a static heart model is almost unchanged when compared with a normal ECG.
Conclusions:
This study confirms the importance of the mechanical factor in the ECG simulation. The dynamic heart model could provide more accurate ECG simulation, especially for myocardial ischemia or infarction simulation, since the main ECG changes occur at the ST segment and T wave, which correspond with cardiac systole and diastole phases.

Abstract
Objective: To analyze clinical features, prognosis and treatment of lymphocytic hypophysitis (LYH). Methods: The clinical data, treatments and outcomes of 18 cases diagnosed as LYH at Chinese PLA General Hospital between January 2001 and July 2017 was respectively reviewed. Results: Eighteen patients with histology-proven LYH (13 females and 5 males ) were identified. All lymphocytic adenohypophysitis (LAH) were females(n=6), two of whom were associated with pregnancy. Eleven patients (6 females and 5 males) had lymphocytic panhypophysitis (LPH) and one(female) had hypothalamitis. Pre-treatment evaluation revealed that 11 patients presented with symptoms of intracranial space-occupying lesions, 12 patients had symptoms of anterior pituitary hormone deficiencies, and 12 patients had central diabetes insipidus (CDI). All patients had space-occupying lesions on magnetic resonance imaging (MRI), which were symmetrically enlarged and homogenously enhanced with or without pituitary stalk thickening. Before or after surgery, 11 patients received immunosuppressant therapy or radiotherapy to alleviate space-occupying effect. After 4-204 months follow-up, 5 patients had a relapse and received immunosuppressants, radiotherapy or surgery to achieve remission. Full recovery (both symptomatic and radiographic) was seen in 6 patients, and 11 patients maintained stable replacement therapy. Conclusions: LYH presents with acute space-occupying effects such as headache, visual disturbances, hypopituitarism, CDI and mild hyperprolactinemia, especially with characteristic radiographic manifestations. Usually, surgery reliably establishes diagnosis, and immunosuppressant therapy is a necessity. On the whole, LYH has a good prognosis.

Abstract
1. Differences in the expression of CIDEa and CIDEc in 20 different tissues were examined. Both CIDEa and CIDEc mRNA transcripts were predominantly but variably expressed in white adipose tissue (WAT) but were also expressed at moderate levels in the kidney and liver and at lower levels in the ovary. Interestingly, among WAT types, both CIDEa and CIDEc were expressed at the lowest levels in heart coronary WAT. 2. To better understand the roles of CIDEa and CIDEc in the fat deposition of broiler chickens, the differences in lipid droplet (LD) size and mRNA levels of CIDEa and CIDEc between lean-type and fat-type broiler chicken lines were studied. LD sizes were larger in fat-type broiler lines, and CIDEa and CIDEc mRNA levels in white adipose, kidney and liver tissues were significantly higher in fat-type broiler lines than in their lean counterparts. 3. Developmental expression patterns of CIDEa and CIDEc mRNA were analysed in different tissue types (WAT, liver and kidney) in Arbor Acres broiler chickens, and CIDEa and CIDEc mRNA expression levels increased during sequential developmental stages, achieving peak expression levels at week 6. 4. These observations suggest that the functions of CIDEa and CIDEc reflect inherent characteristics of lipid metabolism that contribute to the differences in fat deposition between strains. The results in this study contribute to a more robust understanding of the tissue distribution and expression patterns of CIDEa and CIDEc mRNA and facilitate further research concerning the molecular mechanism underlying fat deposition in broiler chickens.
