Abstract
Genomic instability arising from defective responses to DNA damage1 or mitotic chromosomal imbalances2 can lead to the sequestration of DNA in aberrant extranuclear structures called micronuclei (MN). Although MN are a hallmark of ageing and diseases associated with genomic instability, the catalogue of genetic players that regulate the generation of MN remains to be determined. Here we analyse 997 mouse mutant lines, revealing 145 genes whose loss significantly increases (n = 71) or decreases (n = 74) MN formation, including many genes whose orthologues are linked to human disease. We found that mice null for Dscc1, which showed the most significant increase in MN, also displayed a range of phenotypes characteristic of patients with cohesinopathy disorders. After validating the DSCC1-associated MN instability phenotype in human cells, we used genome-wide CRISPR-Cas9 screening to define synthetic lethal and synthetic rescue interactors. We found that the loss of SIRT1 can rescue phenotypes associated with DSCC1 loss in a manner paralleling restoration of protein acetylation of SMC3. Our study reveals factors involved in maintaining genomic stability and shows how this information can be used to identify mechanisms that are relevant to human disease biology1.

Abstract
BACKGROUND To investigate the clinical effects of a unilateral external fixator combined with bone transport and tibio-talar fusion in the treatment of severe postoperative infection of peri-ankle fractures. METHODS The clinical data of 32 patients (22 men and 10 women) with severe postoperative infection of peri-ankle fractures were retrospectively analyzed. Patients' age ranged from 26 to 62 (mean, 42 ± 9.5) years old. The types of fractures were distal tibia fracture (25 cases), distal tibia and fibula fracture (5 cases), and talus fracture (2 cases). All patients underwent treatment with unilateral external fixation combined with bone transport and tibio-talar fusion. 6 patients with severe infection received two-stage treatment involving focal debridement and external fixation, osteotomy, and bone transport. The remaining 26 patients underwent debridement, external fixation, and osteotomy simultaneously. The length of bone transport, total fixation time of the external fixator, and postoperative complications were recorded for all patients. The efficacy of the treatment was assessed using the American Association of Foot and Ankle Society (AOFAS) ankle-hindfoot score. RESULTS Patients were followed up for 16-36 months, with an average follow-up time of 24 months. The length of tibia bone transport ranged from 5 to 15 cm, with a mean length of 8.5 cm. The external fixator was applied for 12-24 months, with an average duration of 16 months. One patient suffered from refracture at tibio-talar fusion site, and one patient had external fixation pin-tract infection. No complications, such as recurrent infections (especially the MRSA infection), poor mineralization, refracture, iatrogenic nerve damage or fusion failure, were found in the remaining patients. The preoperative AOFAS ankle-hindfoot function score was 40.0 ± 3.8 (range, 30-52) points, and it increased to 75.0 ± 3.0 (range, 67-78) points at the last follow-up. CONCLUSION A unilateral external fixator combined with bone transport and tibio-talar fusion is an effective method for treating severe postoperative infection of peri-ankle fractures. This approach is capable of reconstructing large bone defects that remain after clearing the infected lesion. Additionally, it provides stability to the ankle, enhances ankle-hindfoot function, and improves the patient's quality of life.

Abstract
In a recent survey of nematodes associated with tobacco in Shandong, China, the root-lesion nematode Pratylenchus coffeae was identified using a combination of morphology and molecular techniques. This nematode species is a serious parasite that damages a variety of plant species. The model plant benthi, Nicotiana benthamiana, is frequently used to study plant-disease interactions. However, it is not known whether this plant species is a host of P. coffeae. The objectives of this study were to evaluate the parasitism and pathogenicity of five populations of the root-lesion nematode P. coffeae on N. benthamiana.N. benthamiana seedlings with the same growth status were chosen and inoculated with 1,000 nematodes per pot. At 60 days after inoculation, the reproductive factors (Rf = final population densities (Pf)/initial population densities (Pi)) for P. coffeae in the rhizosphere of N. benthamiana were all more than 1, suggesting that N. benthamiana was a good host plant for P. coffeae.Nicotiana. benthamiana infected by P. coffeae showed weak growth, decreased tillering, high root reduction, and noticeable brown spots on the roots. Thus, we determined that the model plant N. benthamiana can be used to study plant-P. coffeae interactions.

Abstract
OBJECTIVES The prognostic value of preimplantation nutritional status is not yet known for older diabetic patients that received right ventricular pacing (RVP). The study aimed to investigate the clinical value of the four malnutrition screening tools for the prediction of heart failure hospitalization (HFH) in older diabetic patients that received RVP. DESIGN Retrospective observational cohort study. SETTING AND PARTICIPANTS This study was conducted between January 2017 and January 2018 at the Fuwai Hospital, Beijing, China, and included older (age ≥ 65 years) diabetic patients that received RVP for the first time Measurements: The Prognostic Nutritional Index (PNI), Geriatric Nutritional Risk Index (GNRI), Naples Prognostic Score (NPS), and the Controlling Nutritional Status (CONUT) score were used to estimate the preimplantation nutritional status of the patients. Univariate and multivariate Cox proportional hazard regression analyses were performed to investigate the association between preimplantation malnutrition and HFH. RESULTS Overall, 231 older diabetic patients receiving RVP were included. The median follow-up period after RVP was 53 months. HFH was reported for 19.9% of the included patients. Our results showed preimplantation malnutrition for 18.2%, 15.2%, 86.6% and 66.2% of the included patients based on the PNI, GNRI, NPS, and CONUT score, respectively. The cumulative rate of HFH during follow-up period was significantly higher for patients in the preimplantation malnutrition group based on the PNI (log-rank = 13.0, P = 0.001), GNRI (log-rank = 8.5, P = 0.01), and NPS (log-rank = 15.7, P < 0.001) compared to the normal nutrition group, but was not statistically significant for those in the preimplantation malnutrition group based on the CONUT score (log-rank = 2.7, P = 0.3). As continuous variables, all the nutritional indices showed significant correlation with HFH (all P < 0.05). However, multivariate analysis showed that only GNRI was independently associated with HFH (HR = 0.97, 95% CI: 0.937-0.997, P = 0.032). As categorical variables, PNI, GNRI, and NPS showed significant correlation with HFH. After adjustment of confounding factors, moderate-to-severe degree of malnutrition was an independent predictor of HFH based on the PNI (HR = 4.66, 95% CI: 1.03-21.00, P = 0.045) and GNRI (HR = 3.02, 95% CI: 1.02-9.00, P = 0.047). CONCLUSION Preimplantation malnutrition was highly prevalent in older diabetic patients that received RVP. The malnutrition prediction tools, PNI and GNRI, showed significant prognostic value in accurately predicting HFH in older diabetic patients with RVP.

Abstract
BackgroundIn lumbo-iliac fixation, the iliac screw can be placed in several locations and directions. There is no uniform standard for the placement of a single iliac screw. Biomechanical tests and finite element analyses were used to compare the effect of bilateral single iliac screws with three channels on pelvic stability to determine the best channel.MethodsFive embalmed adult cadaver pelvic specimens were selected. An unstable Tile C1 pelvic injury model was established. Lumbo-iliac fixation for the treatment of left sacral Denis II fracture includes the following: three channels of bilateral, single iliac screws (channel A from posterior superior iliac spine (PSIS) to anterior inferior iliac spine (AIIS), channel B from 1 cm medial and 1 cm caudal of PSIS to AIIS, and channel C from 2 cm below PSIS to AIIS). Biomechanical testing was performed for stiffness evaluations. A finite element model was established to study the stress distribution of the model and the maximum von Mises stress of internal fixation.ResultsBiomechanical tests revealed that under vertical compression loading. The compressive stiffness fixed by channel B (246.15 ± 27.85 N/mm) was better than that fixed by channel A and channel C. Under torsional load, the torsional stiffness fixed by channel B (2.234 ± 0.223 N·m/°) was stronger than that fixed by channel A and channel C. However, there was no significant difference in terms of compressive and torsional stiffness between channel B and channel A (P > 0.05). Finite element analyses conformed that the maximum von Mises stress of the internal fixator fixed in channel B under the conditions of vertical, forwards bending, backwards extension, left bending, left rotating, and right bending (213.98 MPa, 338.96 MPa, 100.63 MPa, 297.06 MPa, 200.95 MPa and 284.75 MPa, respectively) was significantly lower than those fixed in channel A and channel C.ConclusionsThe construct stiffness of the channel from 1 cm medial and 1 cm caudal of PSIS to AIIS is better than that of the other two channels. This channel has the advantages of good biomechanical stability, small maximum von Mises stress of internal fixation.

Abstract
PURPOSE To prospectively assess the rate of clot resolution from CT pulmonary angiography (CTPA) in patients with acute pulmonary embolism (PE). MATERIALS AND METHODS This prospective cohort study included 290 patients (136 men, 154 women; mean age, 51.9 years) with acute PE. All patients had a CTPA at the presentation and had at least one follow-up within 6 months (mean 72.7 days). Sixty-four percent of patients had follow-up scans for research purposes within a pre-determined period (between 28 and 184 days; mean, 78.27 days) and 36 % had (between 2 and 184 days; mean, 62.78 days) for a clinical indication. The volume of each clot was measured using a semi-automated quantification program. The resolution rate was evaluated by interval-censored analysis. RESULTS The overall estimated probability of complete resolution was 42 % at 7 days, 56 % at 10 days, and 71 % at 45 days. Achieving complete resolution was significantly faster in patients with peripheral clots (HR: 1.78; CI: 1.05-3.03, p = 0.032) but slower in patients with consolidation and history of venous thromboembolism (VTE), (HR: 0.37; CI: 0.18-0.79, p = 0.01 and HR: 0.57; CI: 0.35-0.91, p = 0.019, respectively). Although the patients with cancer showed a faster resolution rate (HR: 1.67; CI: 1.05-2.68, p = 0.032), the mortality rate was significantly higher than non-cancer patients. CONCLUSION The resolution rate of clot burden in acute PE was associated with patients' clinical presentation variables and CTPA imaging biomarkers. This information may be incorporated into designing a prediction rule and determining the appropriate duration of anticoagulation therapy in patients with acute PE.

Abstract
Objectives: To investigate the feasibility of using a porcine fibrin sealant to wrap and remove kidney calculi fragments through an isolated porcine kidney model. Methods: In the isolated porcine kidney stone model (implanted with 100 mg, air dried, ≤1 mm human stone fragments, n=6;implanted with 100 mg, air dried, ≤3 mm human stone fragments, n=6), the ureteral soft mirror combined with the 12/14Fr UAS was used to test the effect of stone extraction using only two stone extraction methods: basket extraction (control group, ≤1 mm stone fragments, n=3; ≤3 mm stone fragments, n=3) and basket-sealant extraction (test group, ≤1 mm stone fragments, n=3; ≤3 mm stone fragments, n=3). Compare the stone removal rate and operation time of the two stone retrieval methods. The sealant was put into urine of normal human and observed. Results: Porcine Fibrin Sealant can form a gel in saline and urine and adhere and wrap stone fragments. The time of procedures of test (basket-sealant) and control (basket) group in kidneys implanted with ≤ 1 mm stone fragments were (14.0±4.2) and (29.0±0.7)min (P<0.05) stone clearance rates were (90.9±1.4)% and (48.4±15.7)% (P<0.05), respectively. In kidneys implanted with ≤ 3 mm fragments, time of procedures were (12.8±4.0) and (30.0±0)min (P<0.05) Stone clearance rates were (91.1±5.0)% and (20.7±8.0)% (P<0.05). The Sealant dissolves by itself in normal human urine and normal saline at 37 ℃ for 24 hours. Conclusion: The appropriate concentration of Porcine Fibrin Sealant assisted stone retrieval may become a new method for removing small stone fragments in retrograde intrarenal surgery.

Title: Characterization of the source(s) of lipocalin-2 mediating dietary obesity-induced hypertension.
Introduction
Obesity upregulates lipocalin-2 (Lcn2), a pro-inflammatory adipokine, which in turn induces vascular and metabolic abnormalities. In mice, deletion of the Lcn2 alleles has protective effects against obesity-induced vascular and metabolic dysfunctions.
Purpose
The present study investigated the sources of lipocalin-2 production as a mediator of dietary obesity-associated perivascular adipose tissue dysfunction and hypertension.
Methods
The wild type (WT) littermates or mice with whole body knockout (LKO), adipose tissue (Adn-Cre)-, kidney (Wt1-Cre)-, liver (Alb-Cre)-, and granuloid cells (Lys-Cre)-selective deletion of the Lcn2 alleles were implanted with radio-telemetry transmitters at eight-weeks of age. Blood pressure was recorded at least four 12/12 light-dark cycles every four weeks for mice fed either standard chow (STC) or high fat diet (HFD). Wire myography was performed to evaluate the functional properties of mesenteric arteries, in the presence or absence of surrounding perivascular adipose tissues. Quantitative PCR, Western blotting as well as enzyme-linked immunosorbent assay (ELISA) were also performed to measure Lcn2 expression in tissues and blood respectively.
Results
Compared to STC, HFD feeding increased systolic, diastolic, mean arterial and pulse pressure in WT mice. The amount of Lcn2 expressed in perivascular adipose tissues and present in blood were also higher in HFD-fed WT mice when compared to those fed with STC. Whole body deletion of Lcn2 alleles attenuated HFD- induced increase in blood pressure. Liver-selective deletion of Lcn2 alleles abolished the effect of HFD feeding on blood pressure, decreased Lcn2 expression in perivascular adipose tissues, and the concentration of Lcn2 in blood. Both whole body- and liver-specific deletion of Lcn2 alleles enhanced the anti-contractile activity of perivascular adipose tissues and abolished HFD-induced adipose tissue dysfunction. However, deletion of Lcn2 alleles selectively in adipose tissues, but not Wt1-Cre and Lys-Cre, partially mitigated the effects of HFD on perivascular adipose tissue function and blood pressure regulation.
Conclusion
Lcn2 derived from different tissues are distinctively implicated in dietary obesity-induced perivascular adipose tissue dysfunction and hypertension.

Abstract
Methacryloyloxydecyl dihydrogen phosphate (MDP) has been speculated to induce mineralization, but there has been no convincing evidence of its ability to induce intrafibrillar mineralization. Polymers play a critical role in biomimetic mineralization as stabilizers/inducers of amorphous precursors. Hence, MDP-induced biomimetic mineralization without polymer additives has not been fully verified or elucidated. By combining 3-dimensional stochastic optical reconstruction microscopy, surface zeta potentials, contact angle measurements, inductively coupled plasma-optical emission spectroscopy, transmission electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy with circular dichroism, we show that amphiphilic MDP can not only demineralize dentin by releasing protons as an acidic functional monomer but also infiltrate collagen fibrils (including dentin collagen), unwind the triple helical structure by breaking hydrogen bonds, and finally immobilize within collagen. MDP-bound collagen functions as a huge collagenous phosphoprotein (HCPP), in contrast to chemical phosphorylation modifications. HCPP can induce biomimetic mineralization itself without polymer additives by alternatively attracting calcium and phosphate through electrostatic attraction. Therefore, we herein propose the dual functions of amphiphilic MDP monomer with de- and remineralizing ability. MDP in the free state can demineralize dentin substrates by releasing protons, whereas MDP in the collagen-bound state as HCPP can induce intrafibrillar mineralization. The dual functions of MDP monomer with de- and remineralization properties might create a new epoch in adhesive dentistry and preventive dentistry.

Abstract
Abstract
Aim
The aim of this study was to perform a systematic review and meta-analysis of existing evidence on the role of hot saline irrigation (HSI) in patients undergoing functional endoscopic sinus surgery (FESS) and its impact on the visibility of the surgical field (VSF).
Method
A search of PubMed, Cochrane, Ovid (including Embase, Medline and Allied and Complementary Medicine Database) databases as well as Google Scholar was performed.
Results
Three randomised control trials (RCT) were included. All three were pooled into meta-analysis which demonstrated a statistically significant better VSF (MD -0.51; 95% CI -0.84, -0.18; P = 0.003), a reduction in total blood loss (TBL) (MD -56.40ml; 95% CI -57.30. -55.51; P = <0.0001) and a reduction in operating time (OT) (MD -7.01mins; 95% CI 9.02mins; 95% CI -11.76, -6.28; P = <0.0001) during FESS in the HSI group compared with the room temperature irrigation control group. Further subgroup analysis of studies that did not use topical vasoconstrictors showed a significant reduction in TBL and OT. There were no reported adverse events related to HSI.
Conclusions
This is the first systematic review that addresses HSI for haemostasis in FESS. The results suggest that HSI in FESS for chronic rhinosinusitis may significantly improve VSF, reduce TBL by 20% and decrease OT by 9 minutes. HSI is cheap and a readily available intervention with a low risk of morbidity and adverse events. However, there are limitations of the study due to significant heterogeneity of methods, quality, and size of the studies.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal (GI) disorders affecting up to 11.5% of the general global population. The brain-gut axis has been shown to play an important role in the pathogenesis of IBS. Several studies confirmed that intrinsic brain abnormalities existed in patients with IBS. But, studies of abnormal regional homogeneity (ReHo) in IBS have reported inconsistent results. The objective of this protocol is to conduct a meta-analysis using the Seed-based d mapping software package to identify the most consistent and replicable findings of ReHo in IBS patients. METHOD We will search the following three electronic databases: MEDLINE, EMBASE and Web of Science. The primary outcome will include the peak coordinates and effect sizes of differences in ReHo between patients with IBS and healthy controls from each dataset. The secondary outcomes will be the effects of age, illness severity, illness duration, and scanner field strength. The SDM approach was used to conduct voxel-wise meta-analysis. Whole-brain voxel-based jackknife sensitivity analysis was performed to conduct jackknife sensitivity analysis. A random effects model with Q statistics is used to conduct heterogeneity and publication bias between studies and meta-regression analyses were carried out to examine the effects of age, illness severity, illness duration, and scanner field strength. RESULTS The results of this paper will be submitted to a peer-reviewed journal for publication. CONCLUSION This research will determine the consistent pattern of alterations in ReHo in IBS patients.

Abstract
OBJECTIVE The anti-inflammatory effect of Sirtuin 1 (Sirt1) during intervertebral disc degeneration (IDD) has been widely confirmed. Monocyte chemoattractant protein-1 (MCP-1) activation is the initiating inflammatory response associated with the IDD. However, whether Sirt1 suppresses MCP-1 in the intervertebral disc is unclear. PATIENTS AND METHODS The MCP-1 and Sirt1 protein expression in the degenerated and non-degenerated NP tissues were compared by immunohistochemistry (IHC). We induced nucleus pulposus (NP) cell degeneration by IL-1β and mediated cellular Sirt1 expression through the Sirt1 activator resveratrol (Res) or inhibitor Nicotinamide (Nico). In addition, the inhibitors of MCP-1 and Activator protein 1 (AP-1) were also used in cell culture. The function of NP cells was determined by the type II collagen and Cell Counting Kit-8 (CCK-8) assay. We assessed the Sirt1 and MCP-1 expression by the Reverse Transcription-quantitative Polymerase Chain Reaction (RT-qPCR). The AP-1 activity was valued by the phosphorylation of its components c-Fos, and c-Jun. RESULTS Both in vivo and in vitro experimental results indicated that MCP-1 was upregulated in the degenerated condition, which was opposite to Sirt1 expression. Res suppressed AP-1, the phosphorylation of c-Fos/c-Jun, and the MCP-1 expression. On the contrary, Sirt1 downregulation by Nico aggravated the phosphorylation of c-Fos/c-Jun and MCP-1 expression. However, the MCP-1 suppression did not affect the Sirt1 and AP-1 levels. The destruction of AP-1 activation also inhibited MCP-1 expression but not Sirt1. The upregulation of Sirt1 and suppression of MCP-1 improved the type II collagen expression and cell viability, which was injured by IL-1β. CONCLUSIONS Sirt1 suppresses the MCP-1 production in the degenerated NP cells by suppressing the phosphorylation of the AP-1 subunits c-Fos and c-Jun.

Abstract
To investigate the role of microRNA-206 (miRNA-206) in the malignant progression of osteosarcoma and the underlying mechanism, expression pattern of miRNA-206 in osteosarcoma tissues and cell lines was determined by quantitative real-time polymerase chain reaction (qRT-PCR). Correlation between miRNA-206 level and prognosis of osteosarcoma patients was analyzed. Regulatory effects of miRNA-206 on the proliferation and metastasis of U2OS and MG63 cells were evaluated by cell counting kit-8 (CCK-8), Transwell and wound healing assay. Through dual-luciferase reporter gene assay, the target gene of miRNA-206 was verified. A series of rescue experiments were conducted to explore the role of miRNA-206/Notch3 in regulating the malignant progression of osteosarcoma. MiRNA-206 was downregulated in osteosarcoma tissues and cell lines, and its level was correlated to poor prognosis and distant metastasis of osteosarcoma patients. Overexpression of miRNA-206 attenuated the proliferative and metastatic abilities of osteosarcoma cells, and miRNA-206 knockdown obtained the opposite trends. Notch3 was verified to be the target gene of miRNA-206, which was upregulated in osteosarcoma and accelerated osteosarcoma cells to proliferate and metastasize. Finally, rescue experiments showed that Notch3 overexpression partially reversed the regulatory effects of miRNA-206 on cellular behaviors of osteosarcoma cells. MiRNA-206 is downregulated in osteosarcoma. Overexpression of miRNA-206 accelerates osteosarcoma cells to proliferate and metastasize by targeting Notch3, thus accelerating the malignant progression of osteosarcoma.

Abstract
In this synthesis, we assess present research and anticipate future development needs in modeling water quality in watersheds. We first discuss areas of potential improvement in the representation of freshwater systems pertaining to water quality, including representation of environmental interfaces, in-stream water quality and process interactions, soil health and land management, and (peri-)urban areas. In addition, we provide insights into the contemporary challenges in the practices of watershed water quality modeling, including quality control of monitoring data, model parameterization and calibration, uncertainty management, scale mismatches, and provisioning of modeling tools. Finally, we make three recommendations to provide a path forward for improving watershed water quality modeling science, infrastructure, and practices. These include building stronger collaborations between experimentalists and modelers, bridging gaps between modelers and stakeholders, and cultivating and applying procedural knowledge to better govern and support water quality modeling processes within organizations.

Abstract
OBJECTIVE Prostate cancer (PC) is one of the most ordinary malignant cancers. Recent researches have proved that long noncoding RNAs (lncRNAs) act as an important role in cancers. Our study aims to explore the function of lncRNA CASC15 in the tumor metastasis of PC. PATIENTS AND METHODS Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was utilized to detect CASC15 expression in 50 PC patients. Besides, the wound healing assay and transwell assay were performed to identify the biological behavior changes of PC cells after CASC15 was silenced in PC cells. In addition, the potential mechanism was also explored using the luciferase assay. RESULTS CASC15 expression level was significantly higher in PC tissues and cell lines. Results of wound healing assay and transwell assay revealed that cell migrated ability and invaded ability were suppressed via silence of CASC15 in PC cells. Furthermore, the expression of miR-200a-3p was upregulated via silence of CASC15 in PC cells. Luciferase assay showed that miR-200a-3p was a direct target of CASC15 in PC. In addition, miR-200a-3p expression was negatively correlated with CASC15 expression in PC tissues. Rescue experiments also revealed that the inhibition of PC migration and invasion by silence of CASC15 could be reversed through knockdown of miR-200a-3p. CONCLUSIONS Our study uncovers that CASC15 could enhance cell migration and invasion of PC cells by sponging miR-200a-3p, which might be applied as a novel therapeutic target for PC patients.

Abstract
Odontogenic infections can become life-threatening if not managed in a timely manner, and they increase the physical cost of treatment to the patient and the financial cost to the public health system. We investigated the number of admissions to a Queensland tertiary hospital within a decade, and differences in the patients' characteristics, severity at presentation, and clinical outcomes. We compared patients with odontogenic infections who were taken to theatre at the Royal Brisbane & Women's Hospital (RBWH) between January 2003 and December 2004 with those treated between January 2013 and December 2014, a total of 292. Data on demographics, presentation, previous history, antimicrobial treatment, and admissions, were collated and analysed. There were no significant differences in demographics. In the 2013/2014 group there was a two-fold increase in infections related to lower third molars (p=0.001), a 50% increase in trismus (p=0.001), and a 20% increase in submandibular swelling (p=0.010). The percentage of patients admitted to the intensive care unit (ICU) was three and a half times higher in the 2013/2014 group (p=0.001). The presentation of odontogenic infections has increased in the decade from 2003/2004 to 2013/2014. Measures of the severity of disease have increased, while the basic characteristics of the patients have remained constant. Improved primary preventative measures and early interventions are therefore needed to alleviate the burden that these infections place on the public health system.

Abstract
Tertiary lymphoid structure (TLS) provides a local and critical microenvironment for both cellular and humoral immunity and supports effective antigen presentation and lymphocyte activation. However, the gene expression profile and prognostic significance of TLS in oral cancer remain largely unrevealed. In this study, we found the presence of both intratumoral and peritumoral TLSs in a series of 65 patients with oral cancer treated by surgical resection, with positive detection rates of 33.8 and 75.4%, respectively. The presence of intratumoral TLSs, but not peritumoral TLSs, was significantly associated with decreased P53 and Ki67 scores (P = 0·027 and 0·047, respectively). The survival analyses revealed that oral cancer patients with higher grades of TLSs was associated with improved disease-free survival (DFS) and overall survival (OS) (P = 0·037 and 0·031, respectively). Gene expression profiling analysis of the cytokines and chemokines responsible for lymph-node neogenesis identified a three-up-regulated-gene set, i.e. IL7, LTB and CXCL13, which was shown to be correlated with human oral cancer-associated TLSs. This study provides a framework for better understanding of oral cancer-associated TLSs and for delineating future innovative prognostic biomarkers and immune therapeutic strategies for oral cancer.

Abstract
Background Pelvic ring fractures associated with vaginal injuries were rarely reported due to low incidence. The displaced segments of pelvic ring may increase the risk of vaginal injury. The aim of this retrospective study was to evaluate the correlation between pelvic fracture and vaginal injury. Methods We conducted a retrospective review of 25 patients with pelvic fractures associated with vaginal injury treated at our institution. The medical records of these patients were collected and 24 patients were followed-up for 10–36 months. Results All patients suffered anterior pelvic ring fracture. Young-Burgess fracture classification and compromised pubic symphysis were related to severity of vaginal injury. Gauze packing was done in 6 patients and 18 patients received surgical repair. Infection occurred in 6 patients, among them 4 were due to delayed diagnosis. Factors associated with pelvic outcome were age, urethral injury, and infection. Four patients suffered pain in sexual intercourse but no influence factor found correlated to sexual function. Conclusion VS type pelvic fracture and compromised pubic symphysis were related to higher severity of vaginal injury. Disruption of anterior ring and an unstable pelvic ring caused by forces on coronary and axial plane may increase the risk of vaginal injury. Trial registration ChiCTR1900020540.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) play an important role in the process of bone repair. The present study investigated the effect of 5-azacytidine (AZA) and trichostatin A (TSA) on BMSC behaviors in vitro. The role of WNT family member 5A (WNT5A)/WNT family member 5A (WNT7A)/beta-catenin signaling was also investigated. BMSCs were isolated from a steroid-induced avascular necrosis of the femoral head (SANFH) rabbit model. The third-generation of BMSCs was used after identification. The results revealed obvious degeneration and necrosis in the SANFH rabbit model. AZA, TSA and TSA + AZA increased BMSC proliferation in a time-dependent fashion. AZA, TSA and TSA + AZA induced the cell cycle release from the G0/G1 phase and inhibited apoptosis in BMSCs. AZA, TSA and TSA + AZA treatment significantly decreased caspase-3 and caspase-9 activities. The treatment obviously increased the activity and relative mRNA expression of alkaline phosphatase. The treatment also significantly up-regulated the proteins associated with osteogenic differentiation, including osteocalcin and runt-related transcription factor 2 (RUNX2), and Wnt/beta-catenin signal transduction pathway-related proteins beta-catenin, WNT5A and WNT7A. The relative levels of Dickkopf-related protein 1 (an inhibitor of the canonical Wnt pathway) decreased remarkably. Notably, TSA + AZA treatment exhibited a stronger adjustment ability than either single treatment. Collectively, the present studies suggest that AZA, TSA and TSA + AZA promote cell proliferation and osteogenic differentiation in BMSCs, and these effects are potentially achieved via upregulation of WNT5A/WNT7A/b-catenin signaling.

Abstract
Background Socioeconomic inequality in child mortality highlights opportunities for policies to reduce child deaths. Methods We used singleton birth, death and maternity records from Scotland, 1981-2011, to examine mortality rate differences by age across deprivation quintiles over time. We measured the difference between the most and least deprived quintiles (Q5-Q1) and the slope index of inequality (SII) across all quintiles-measures of the absolute deprivation gap, providing an indication of the public health impact. Results Q5-Q1 remained relatively constant from 1990 onwards for early neonates, widened in the mid-2000s for late neonates, increased in the 1990 s then decreased in the 2000 s in the post-neonates and declined over time in early childhood. The trend over time in SII showed no significant change for early neonates (P = 0.440), significant decrease for post-neonates (P = 0.010) and early childhood (P = 0.043), and significant increase for late neonates (P = 0.011). Conclusions Over three decades, the absolute deprivation gap in mortality widened in late neonates but stabilized or declined at other ages. This may reflect improved survival beyond the early neonatal period of babies with conditions related to socioeconomic inequality such as prematurity. Monitoring birth cohort data could enhance understanding of this vulnerable group.

Abstract
BACKGROUND AND OBJECTIVES Stem cell factor (SCF), the ligand of the c-kit receptor, actively participates in the organ reconstruction and fibrosis associated with various diseases, including kidney disease. However, it remains unclear whether SCF plays a role in kidney aging. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS In the present study, we measured the serum SCF level, estimated glomerular filtration rate (eGFR), and other biological parameters in a Chinese Han group of 892 subjects, and explored the relationship between SCF level and renal function during aging; we sought to define novel biomarkers of kidney aging. RESULTS Multiple linear regression was used to select potential indicators of decline in renal function. Only age, SCF level, and 25% maximum expiratory flow (25% MEF) were significant predictors after redundancy analysis (|r| > 0.70 and P < 0.05). Multiple linear regression showed that the relationship among eGFR, SCF level, and age could be described as follows: eGFR = 154.486 - (0.846 × age) - (0.011 × SCF level). CONCLUSIONS We found no between-gender difference in the effect of SCF on kidney aging. In conclusion, the SCF level is an ideal biomarker of renal aging and may help to predict changes in eGFR during aging.

Abstract
Circular RNAs (circRNAs) are a new class of RNAs that can be used as biomarkers in clinical blood samples. However, little is known about circRNAs' diagnostic values for rheumatoid arthritis (RA). In this study, the hsa_circ_0054189, hsa_circ_0008675, hsa_circ_0082689, hsa_circ_0082688, hsa_circ_0010932, hsa_circ_0002473 and hsa_circ_0044235 in peripheral blood were determined by quantitative reverse transcription–polymerase chain reaction (qRT–PCR). For hsa_circ_0044235, only one abnormal expression circRNAs in peripheral blood was selected as a targeted circRNA to explore the diagnostic value for RA. Our work demonstrated that the hsa_circ_0044235 in peripheral blood was decreased significantly in RA patients. The hsa_circ_0044235 in peripheral blood from RA patients did not correlate with C‐reactive protein (CRP), erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), anti‐citrullinated protein antibodies (ACPA) or disease activity score 28 (DAS28). Receiver operating characteristic (ROC) curve analysis suggested that the hsa_circ_0044235 in peripheral blood has significant value in the diagnosis of RA. The risk score based on hsa_circ_0044235 in peripheral blood also distinguished significantly the patients with RA from systemic lupus erythematosus (SLE). This study suggests that the hsa_circ_0044235 in peripheral blood may be a potential biomarker of patients with RA.

Abstract
The efficacy and safety of an investigational combination of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) plus sofosbuvir (SOF) ± ribavirin (RBV) in patients with HCV genotype 2 or 3 infection with or without cirrhosis was evaluated. Patients with HCV genotype 3 infection without cirrhosis were randomized to receive OBV/PTV/r + SOF ± RBV for 12 weeks; OBV/PTV/r + SOF + RBV was administered to genotype 3-infected patients with cirrhosis for 12 weeks and to genotype 2-infected patients without cirrhosis for either 6 or 8 weeks. Efficacy was assessed by sustained virologic response [HCV RNA <25 IU/mL] 12 weeks post-treatment (SVR12). Safety was assessed in all treated patients. In patients with genotype 3 infection with or without cirrhosis treated with 12 weeks of OBV/PTV/r + SOF ± RBV, the overall SVR12 rate was 98% (50/51), with no virologic failures. Patients with genotype 2 infection treated with OBV/PTV/r + SOF + RBV had SVR12 rates of 90% (9/10) and 44% (4/9) following 8- and 6-week treatment durations, respectively; failure to achieve SVR12 for these patients was due to relapse without baseline or treatment-emergent resistance-associated substitutions. Thus, the investigational combination of OBV/PTV/r with SOF ± RBV was well tolerated and achieved high SVR rates with no virologic failures in patients with genotype 3 infection. Combining direct-acting antivirals with complementary mechanisms of action and different viral targets may be an effective treatment strategy that may allow for shorter durations of therapy.

Abstract
OBJECTIVES We aimed to evaluate the relationship between baseline renal function and changes in telomere length in Han Chinese. METHODS The telomere restriction fragment (TRF) length of leukocytes in the peripheral blood was measured in healthy volunteers recruited in 2014. The estimated glomerular filtration rate (eGFR) was calculated based on serum creatinine (Scr) and serum cystatin C (CysC)-eGFRcys and eGFRScr-cys through the Cockcroft-Gault formula (eGFRC-G) or the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI / eGFRCKD-EPI) equation. The correlation between telomere length changes over time and renal function was analyzed. RESULTS Leukocyte TRF lengths were negatively correlated to age (r = -0.393, p < 0.001) and serum CysC (r = -0.180, p < 0.01), while positively associated with eGFRCKD-EPI, eGFRC-G, eGFRcys, and eGFRScr-cys (r = 0.182, 0.122, 0.290, and 0.254 respectively, p < 0.01). The 3-year change of telomere length was 46 bp/years. When adjusted for age, the associations between telomere length changes and baseline, subsequent TRF lengths, and serum CysC were no longer present. No association was observed between TRF length changes and renal function. CONCLUSION The rate of telomere length changes was affected by age and baseline telomere length. The telomere length changes might be important markers for aging.

Abstract
Animal brucellosis is a re-emerging disease in China with high prevalence in the northwest region. A total of 66 isolates of Brucella were recovered from sheep and yaks in the Inner Mongolia, Xinjiang, Qinghai and Gansu provinces of northwest China in 2015 and 2016. Using classical biotyping and the Brucella AMOS PCR assay, all isolates were identified as Brucella melitensis biovar 3 (n = 58), B. melitensis biovar 1 (n = 1), Brucella abortus (n = 5), or Brucella suis biovar 3 (n = 2), and B. melitensis biovar 3 was found to be mainly responsible for sheep brucellosis in northwest China. Multilocus variable-number tandem-repeat analysis (MLVA) was used to identify the epidemiological relationships among the isolates and to assess their genetic diversity. Multilocus variable-number tandem-repeat analysis-16 identified 46 genotypes in these populations, including 37 unique and nine shared genotypes. Multilocus variable-number tandem-repeat analysis-11 showed that 71% of the isolates (47 of 66) were genotype 116 (1-5-3-13-2-2-3-2-4-41-8), a characteristic subgroup of the East Mediterranean group, showing that isolates from different geographical areas exhibit similar epidemiological characteristics in different regions and may be epidemiologically linked. Multilocus variable-number tandem-repeat analysis-11 also revealed that an isolate from Inner Mongolia had a novel genotype, 369 (1-5-3-13-2-2-3-2-7-41-8). Multilocus variable-number tandem-repeat analysis-16 genotyping of northwest China Brucella isolates allows a better understanding of the epidemiology of animal brucellosis in this region. This study is the first analysis of B. melitensis in Gansu province, and the results confirmed that in this province, isolates of this species are disorderly and unsystematic.

Abstract
The aim of the present study was to provide a novel method for the diagnosis, prevention and treatment of endometrial cancer by the determination of the characteristic expression of the eukaryotic translation initiation factor 4E (eIF4E) and the enzyme matrix metalloproteinase 9 (MMP9) in endometrial cancer tissue. Three types of endometrial tissue specimens were selected (including 20 cases of normal endometrial tissue specimens, 15 cases of hyperplastic endometrial tissue specimens and 45 cases of endometrial cancer tissue specimens). The expression of eIF4E and MMP9 in the specimens was examined by immunohistochemistry and their corresponding levels were statistically analyzed. The positive expression rates of eIF4E and MMP9 in endometrial cancer specimens were 64.44% and 66.67% respectively, which were higher than those noted in hyperplastic endometrial tissue specimens and normal endometrial tissue specimens (p less than 0.05). The comparisons between the groups indicated that the expression levels of eIF4E and MMP9 in the endometrial cancer specimens were increased compared with those noted in the normal endometrial tissue specimens (p less than 0.0167). In endometrial cancer specimens, the positive expression rates of eIF4E and MMP9 were related to the endometrial cancer stages as determined by the International Federation of Gynecology and Obstetrics (FIGO), tumor cell differentiation degree and lymphatic metastasis (p less than 0.05) classifications. eIF4E expression was positively related to MMP9 expression in endometrial cancer specimens. High expression levels of eIF4E and MMP9 proteins were noted in endometrial cancer specimens, which were correlated with FIGO stages, histological grade and degree of lymphatic metastasis. Thus, endometrial cancer and malignant biological behavior may be connected to the high expression of eIF4E and MMP9. The positive correlation between eIF4E and MMP9 expression in endometrial cancer specimens suggests their potential up-regulation during carcinogenesis.

Abstract
OBJECTIVE To investigate the optimal anticoagulation methods and monitoring strategy for Chinese patients undergoing heart valve replacement, which is potentially quite different from western populations. METHODS In this multicenter prospective cohort study, the anticoagulation and monitoring strategy data was acquired from 25 773 in-hospital patients in 35 medical centers and 20 519 patients in outpatient clinic in 11 medical centers from January 1st, 2011 to December 31th, 2015. RESULTS As for in-hospital patients, mean age of study population was (48.6±11.2) years old; main etiology of valve pathology was rheumatic (87.5%) origin among study cohort; 94.8% of study population received mechanical valve implantation; international normalized ratio (INR) monitoring (in all the study centers) and low-intensity anticoagulation strategy (31 hospitals chose target INR range of 1.5-2.5, and actual values of INR among 89.2% of 100 069 in-hospital monitoring samples were 1.5-2.5), with mean actual INR values of 1.84±0.53, and warfarin dosage of (2.82±0.93) mg/d were widely adopted among the study centers; strategies of in-hospital warfarin administration were similar in all the study centers; complication rates of low-intensity anticoagulation strategy were low in severe hemorrhage (0.02%), thrombosis (0.05%), and thromboembolism (0.05%) events, without anticoagulation-related death.As for 18 974 outpatient clinic patients, the follow-up rate was 92.47%, with a total of 30 012 patient-years (Pty). Anticoagulation-related morbidity and mortality rates were 0.67% and 0.15% Pty; major hemorrhage morbidity and mortality rates were 0.25% and 0.13% Pty; thromboembolism morbidity and mortality rates were 0.45% and 0.03% Pty.The mean dosage of warfarin daily dosage was (2.85±1.23) mg/d and INR value was 1.82±0.57.No significant regional difference in the intensity of anticoagulation therapy was noted during the study. CONCLUSIONS INR can be used as a normalized indicator for intensity of anticoagulation therapy in China.The optimal anticoagulation intensity with INR range from 1.5 to 2.5 is safe and effective for Chinese patients with heart valve replacement, and there is no significant regional difference in the intensity of anticoagulation therapy.

Abstract
Background Plate fixation is the gold standard for diaphyseal fracture management, and the anterolateral approach is widely used by reconstructive surgeons. However, the outcomes of humeral shaft fracture fixation using a medial approach are rarely reported. The aim of this study is to explore the management and outcomes of humeral mid-shaft fractures fixed through a medial incision. Methods Thirty-four patients who sustained a humeral mid-shaft fracture and underwent an open-reduction internal fixation (ORIF) in our department between January 2010 and January 2013 were included in this study. Sixteen patients had an ORIF performed through a medial approach, while the remaining 18 were fixed through an anterolateral approach. Postoperative clinical and radiographic results were reviewed. Results There were no significant differences in the blood loss and the range of motion of the shoulder and elbow between the anterolateral and medial fixation groups. One patient in the medial group and two patients in the anterolateral group had radial nerve dysfunction that improved after 8, 3 and 6 weeks, respectively. All patients healed radiographically except one from the anterolateral group who underwent grafting and re-fixation for a non-union. No vascular injuries, infections, malunions, broken plates or loose screws were noted in either group. Conclusions The medial approach to the humerus had equivalent outcomes to anterolateral fixation. It is an available choice for humeral mid-shaft fracture fixation in cases where there is no need to expose the radial nerve. The medial approach does not require a pre-bent plate and creates a large operative exposure. A well-hidden incision can also be designed, improving cosmetic outcomes. However, the medial approach is not suitable to proximal or distal humerus fractures.

Abstract
While uncommon, post-traumatic pelvic malunions present reconstructive challenges and are associated with significant disability and financial burden. A transiliac osteotomy is a surgical technique useful to correct certain types of pelvic fracture malunions, and is only used when the correction of a limb-length discrepancy is the primary goal. This study aims to present our experience with this technique in the treatment of post-traumatic pelvic malunions. Eight patients who underwent transiliac osteotomies for post-traumatic pelvic malunions at our department from 2006 to 2011 were included in this study. We reviewed the clinical and radiographic results of these patients. By the time of their last follow-up, all osteotomy sites and iliac bone graft had healed with no evidence of internal fixation failure. Of the 3 patients who complained of preoperative posterior pain, 2 reported an improvement. All 8 patients noted the resolution of their lower back pain. At the time of their final follow-up, 4 patients could walk normally, 2 had a slight limp without a cane, 1 patient used a cane to help with standing and walking, and the final felt limited during ambulation with a cane. Limb-lengthening relative to preoperative measurements was 2.86 cm (2.2-3.0 cm) at the time of the last follow-up. Two patients were able to return to their previous jobs, 4 patients changed their jobs or engaged in light manual labor while the final 2 were able to perform activities of daily living but were unable to participate in work or labor. Three patients reported being "extremely satisfied" with their outcomes, 3 were "satisfied," and 2 were "unsatisfied." A transiliac osteotomy can be used to manage selected cases of post-traumatic pelvic malunions that are unable to be corrected with a traditional release and osteotomy. However, in these cases the correction of limb-length discrepancies should be the primary reconstructive goal.

Abstract
We studied the association between aldehyde dehydrogenase 2 (ALDH2) polymorphism and coronary artery disease (CAD) and clarified the mechanisms underlying this association. We searched the ISI, Medline (Ovid), PubMed, CNKI, Wanfang, and Weipu Databases. Statistical analysis was performed using Revman 5.0 and Stata12.0 softwares. A total of 3305 cases and 5016 controls in 12 case-control studies were included in this meta-analysis. Variant A allele carriers showed a 48% increased risk of CAD compared with homozygote A allele [odds ratio (OR) = 1.48, 95% confidence interval (CI) = 1.18-1.87 for AA + AG vs GG]. In subgroup analysis by gender, significantly elevated risks were found in the mixed group (OR = 1.78, 95%CI = 1.42-2.22) but not in males (OR = 1.12, 95%CI = 0.79-1.57). In subgroup analysis by disease type, significant elevated risks were associated with A allele carriers in myocardial infarction [OR = 1.69, 95%CI = (1.05-2.71)], in coronary heart disease (OR = 1.36, 95%CI = 1.00-1.86), but not in coronary heart disease plus diabetes mellitus subjects (OR = 1.57, 95%CI = 0.58-4.29). Moreover, those with the GG genotype consumed significantly more alcohol than those with the AA/AG genotypes (standard mean deviation: 6.32 g, 95%CI = 2.09-10.55, P = 0.000). ALDH2 polymorphisms may be risk factors for CAD. Moreover, CAD patients with ALDH2 genotypes AG and AA consumed significantly less alcohol than those with GG. To further evaluate gene-gene and gene-environment interactions between ALDH2 polymorphisms and the risk of CAD, more studies with larger groups of patients are required.
