Abstract
BACKGROUND Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable myocardium disorder that predominantly affects the ventricle. Little is known about atrial involvement. This study aimed to assess atrial involvement, especially the role of genotype on atrium in ARVC. METHODS The incidence, characterization and predictors of atrial involvement were investigated. Nine known ARVC-causing genes were screened and the correlation between genotype and atrial involvement was assessed. RESULTS Right atrium (RA) dilation, left atrium (LA) dilation, and sustained atrial tachyarrhythmias (ATa) were found in 45, 16 and 3 patients, respectively. Gene mutations were identified in 64 (64.0%) patients. Mutation carriers showed more RA dilation than noncarriers (54.7% vs. 27.8%, P = 0.009), and no difference in LA dilation and ATa. Multivariate analysis showed tricuspid regurgitation (OR: 18.867; 95% CI: 1.466-250.000; P = 0.024) increased the risk of RA dilation and decreased left ventricular ejection fraction (LVEF) (OR: 1.134; 95% CI: 1.002-1.272; P = 0.031) correlated with LA dilation, whereas genotype showed no significant effect. At a median follow-up time of 91 months, 7 patients died and 1 patient accepted heart transplantation. New-onset RA dilation, LA dilation, and sustained ATa were found in 8, 7, and 6 patients, respectively. Atrial involvement was not associated with the long-term survival. Despite mutation carriers showing more RA dilation, Kaplan-Meier analysis showed genotype was not associated with atrial involvement. CONCLUSION Atrial involvement was common in ARVC. Tricuspid regurgitation and decreased LVEF increased the risk for atrial dilation. Genotype was not associated with atrial involvement.

Abstract
We aimed to describe the current state of specialist obesity services for adults with clinically severe obesity in public hospitals in Australia, and to analyse the gap in resources based on expert consensus. We conducted two surveys to collect information about current and required specialist obesity services and resources using open-ended questionnaires. Organizational level data were sought from clinician expert representatives of specialist obesity services across Australia in 2017. Fifteen of 16 representatives of current services in New South Wales (n = 8), Queensland (n = 1), Victoria (n = 2), South Australia (n = 3), and the Australian Capital Territory (n = 1) provided data. The composition of services varied substantially between hospitals, and patient access to services and effective treatments were limited by strict entry criteria (e.g. body mass index 40 kg/m2 or higher with specific complication/s), prolonged wait times, geographical location (major cities only) and out-of-pocket costs. Of these services, 47% had a multidisciplinary team (MDT), 53% had an exercise physiologist/physiotherapist, 53% had a bariatric surgeon and 33% had pharmacotherapy resources. Key gaps included staffing components of the MDT (psychologist, exercise physiologist/physiotherapist) and access to publicly funded weight loss pharmacotherapy and bariatric surgery. There was consensus on the need for significant improvements in staff, physical infrastructure, access to services, education/training in obesity medicine and targeted research funding. Based on the small number of existing, often under-resourced specialist obesity services that are located only in a few major cities, the vast majority of Australians with clinically severe obesity cannot access the specialist evidence based treatments needed.

Abstract
Objective: To investigate whether CD137-CD137L signaling can affect the autophagy of mouse vascular smooth muscle cells(VSMCs) through JNK signal pathway. Methods: Primary culture of C57BL/6J mouse thoracic aorta VSMCs was performed by tissue block adherence method. VSMCs between the third to fifth passages were isolated and cultured. VSMCs were divided into 4 groups: control group, CD137 agonist group, JNK inhibition group, and DMSO group. VSMCs in CD137 agonist group were treated with recombinant protein of CD137L (10 μg/ml), VSMCs in JNK inhibition group were treated with JNK inhibitor SP600125 (10 μmol/L) for 30 minutes followed by recombinant protein of CD137L (10 μg/ml) and DMSO group was treated with the same amount of DMSO in JNK inhibition group for 30 minutes, then added recombinant protein of CD137L (10 μg/ml). Western blot was used to detect the protein expression of p-JNK, LCⅡ and p62 in each group. Fluorescence microscopy was used to track the changes of autophagy in cells which was infected with adenovirus expressing tandem mRFP-GFP-LC3. Transmission electron microscope (TEM) was used to observe intracellular autophagosomes and autolysosomes. Results: (1) Compared with the control group, stimulating CD137-CD137L axis by recombinant protein of CD137L significantly upregulated the expression of p-JNK, LCⅡ and p62 (1.15±0.19 vs. 0.72±0.21, P<0.05;1.03±0.13 vs. 0.59±0.15, P<0.05, and 1.10±0.19 vs. 0.76±0.15, P<0.05). These effects could be reduced by JNK inhibitor (0.61±0.21 vs. 1.15±0.19, P<0.05;0.74±0.11 vs. 1.03±0.13, P<0.05, and 0.21±0.12 vs. 1.10±0.19, P<0.05). The expression of these proteins in DMSO group remained unchanged compared with CD137 agonist group (P>0.05). (2) Changes of autophagy in cells of various group: the number of total fluorescent spots and yellow fluorescent spots in CD137 agonist group was significantly increased compared to control group (total fluorescent spots:(93.00±14.11)/cell vs. (52.33±9.61)/cell, P<0.05, and (64.33±6.81)/cell vs. (25.67±3.51)/cell, P<0.05), moreover, the number of yellow fluorescent spots was higher than the red fluorescent spots fluorescent spots in CD137 agonist group. Compared with CD137 agonist group, pretreatment with JNK inhibitor significantly reduced the number of total fluorescent spots and yellow fluorescent spots ((53.00±3.17)/cell vs. (93.00±14.11)/cell, P<0.05,and (15.33±4.51)/cell vs. (64.33±6.81)/cell, P<0.05). The red fluorescent spots were higher than the yellow fluorescent spots in JNK inhibition group. The number of total fluorescent spots and yellow fluorescent spots in CD137 agonist group was not affected by pretreatment with DMSO (P>0.05). (3) The number of intracellular autophagosomes and autolysosomes was significantly higher in CD137 agonist group than in control group((17.67±6.03)/cell vs. (5.67±2.52)/cell, P<0.05), and the number of autophagosomes was higher than that of autolysosomes in CD137 agonist group((14.00±4.00)/cell vs. (3.67±2.08)/cell, P<0.05). The number of intracellular autophagosomes and autolysosomes was significantly lower in JNK inhibition group compared to CD137 agonist group((5.67±4.04)/cell vs. (17.67±6.03)/cell, P<0.05) and the number of autophagosomes was lower than that of autolysosomes in JNK inhibition group((1.33±1.53)/cell vs. (4.33±2.52)/cell, P<0.05). The number of intracellular autophagosomes and autolysosomes was similar between DMSO group and CD137 agonist group (P>0.05). Conclusion: CD137-CD137L signal may influence autophagy of mouse VSMCs via JNK pathway.

Abstract
Objective: To explore the relationship between abnormal expression of fragile histidine triad (FHIT) gene and methyl-CpG-binding protein 2 (MeCP2) as well as their interaction on cervical cancerization. Methods: A total of 73 patients with cervical squamous cell carcinoma (SCC), 113 patients with cervical intraepithelial neoplasia (CIN Ⅰ, n=45; CINⅡ/Ⅲ, n=68) and 60 women with normal cervix (NC) were included in the study. Real time PCR and Western blot were performed to detect the expression levels of mRNA and protein about FHIT and MeCP2, respectively. The methylation status of FHIT gene CpG island was tested by methylation-specifc PCR (MSP). Kruskal-Wallis H test, χ(2) test, trend χ(2) test and Spearman correlation analysis were conducted with software SPSS 20.0. The interaction was evaluated by generalized multifactor dimensionality reduction (GMDR) model. Results: With the deterioration of cervical lesion, the methylation rates of FHIT gene CpG island (χ(2)=18.64, P<0.001; trend χ(2)=18.08, P<0.001) increased gradually, while the expression levels of FHIT mRNA (H=27.32, P<0.001; trend χ(2)=12.65, P<0.001) and protein (H=47.10, P<0.001; trend χ(2)=29.79, P<0.001) decreased gradually. There was a negative correlation between the methylation rates of FHIT gene CpG island and the expression level of FHIT protein (r=-0.226, P<0.001). The levels of MeCP2 mRNA (H=26.19, P<0.001; trend χ(2)=11.81, P=0.001) and protein (H=69.02, P<0.001; trend χ(2)=47.44, P<0.001) increased gradually with the aggravation of cervical lesions. There was a positive correlation between the expression level of MeCP2 protein and the FHIT mRNA Ct ratio (r=0.254, P<0.001). Expression of proteins were negatively correlated between MeCP2 and FHIT (r=-0.213, P=0.001). The results analyzed by GMDR model showed that there were interactions among high MeCP2 protein expression, the CpG island methylation of FHIT and mRNA and protein expression in CINⅡ/Ⅲ group, and among high MeCP2 mRNA and protein expression, the CpG island methylation of FHIT and low mRNA and protein expression in SCC group. Conclusion: High expression of MeCP2 mRNA and protein, the CpG island methylation and low mRNA and protein expression of FHIT could increase the risk of cervical carcinogenesis, and there might be a synergistic effect on cervical carcinogenesis.

Abstract
Objective: To evaluate the effects of polycyclic aromatic hydrocarbons (PAHs) and high risk human papillomavirus (HR-HPV) infection and their interaction on the progression of cervical intraepithelial neoplasia. Methods: A total of 486 patients, including 208 women with normal cervix (NC), 154 patients with low-grade cervical intraepithelial neoplasm (CINⅠ), 124 patients with high-grade cervical intraepithelial neoplasm (CINⅡ/Ⅲ), were selected from the cervical lesions cohort from June to December, 2014. HR-HPV was detected by using flow-through hybridization technology and the urine concentration of 1-hydroxypyrene (1-OHP) was detected with high performance liquid chromatography. By using software SPSS 22.0, the χ(2) test, trend χ(2) test, Kruskal-Wallis H test, Nemenyi rank test and Spearman rank correlation analysis were performed. And the interaction effects were evaluated by additive model. Results: The HR-HPV infection rates in NC, CINⅠ and CINⅡ/Ⅲ groups were 27.9%, 37.0% and 58.9%, respectively. The urine concentrations of 1-OHP (μmol/molCr) were 0.07±0.09, 0.11±0.10 and 0.17±0.15, respectively. With increasing severity of the cervical lesions, the HR-HPV infection rate gradually increased (trend χ(2)=29.89, P<0.001) and the high exposure rate of PAHs gradually increased (trend χ(2)=27.94, P<0.001). HR-HPV infection was positively correlated with 1-OHP exposure (r=0.680, P<0.001). There was a positive additive interaction between HPV infection and PAHs exposure in CIN Ⅱ/Ⅲ group, but it was not found in CIN Ⅰ group. Conclusion: Both HR-HPV infection and high exposure of PAHs might increase the risk of cervical intraepithelial neoplasm, and might have a synergistic effect on the progression of high-grade cervical intraepithelial neoplasia.

Abstract
Objective: To investigate the clinicopathologic and molecular features of the rare cribriform morular variant of papillary thyroid carcinoma (CMV-PTC). Methods: The clinicopathologic data of 10 patients with CMV-PTC were retrospectively reviewed. Immunohistochemical (IHC) staining was done using LSAB method. DNA sequencing for APC were applied using Sanger method. BRAF V600E mutation was examined using ARMS method. The cytological, morphological, IHC and molecular features were analyzed. Results: All patients were female at an average age of 27 years old. The tumors were mostly located in the right lobe of thyroid. Fine needle aspiration cytology was performed in three patients; two were diagnosed as suspicious for PTC and one as PTC. Nine tumors presented as solitary nodule and two as multiple nodules in both lobes. Infiltration was demonstrated in three cases. The average size was 2.6 cm. The neoplastic cells were arranged in papillary, cribriform, solid and glandular patterns, with rare or without colloid inside the lumen. The number of morula varied, ranging from zero to many. The neoplastic cells were variably enlarged, showing round, oval or spindle shape. Nuclear irregularity was identified as irregular membrane, nuclear grooves or pseudoinclusion, but no typical ground glass feature. Peculiar nuclear clearing could be observed in the morular cells. IHC staining showed the neoplastic cells were negative for thyroglobulin and p63, but positive for TTF1, cytokeratin 19 and estrogen receptor. Diffuse staining with cytokeratin was seen in the neoplastic cells and the morula. Specific cytoplasmic and nuclear staining of β-catenin was seen in the neoplastic cells but not the morula. Ki-67 proliferation index was 1%-30%. No recurrence or metastasis was observed. One patient was demonstrated to harbor both somatic and germline mutations of the APC gene, who was found to have adenomatous polyposis and her mother died of colonic carcinoma. No BRAF V600E mutation was detected. Conclusions: CMV-PTC is rare and shows atypical cytological and clinicopathological features, and it is easily misdiagnosed.TG, TTF1, ER and β-catenin are specific IHC markers for CMV-PTC. The morula is negative for cytokeratin 19, in contrast to squamous metaplasia. Although CMV-PTC has indolent clinical behavior, a definite diagnosis is necessary to rule out the possibility of APC gene mutation and related extra-thyroidal neoplasm, such as FAP and Gardner syndrome.

Abstract
Lymph node metastasis is a decisive factor for performing postoperative radiotherapy for oral squamous cell carcinoma (OSCC). However, whether OSCC patients with only micrometastasis need postoperative radiotherapy is unclear. In this study, OSCC patients (n = 311) with negative (n = 247), only micrometastasis (n = 44) and macrometastasis (n = 20) were detected and selected by HE staining. Micrometastasis was re-assessed using immunohistochemical staining of cytokeratin (CK) in HE-negative patients to find out the false negative cases. The results indicated that, among the negative lymph node cases (n = 247), the positive rate of CK was 4.94% (n = 12). Besides, the clinical features of the primary tumor in relation to the only micrometastatic status and the value of the postoperative radiotherapy on the only micrometastasis patients were evaluated. Patients with only micrometastasis had higher T stage and inferior worst pattern of invasion (WPOI) than patients without micrometastasis, but they had longer overall survival (OS), metastasis-free survival (MFS), and disease-free survival (DFS) than macrometastasis patients. However, the survival time of only micrometastasis patients with or without postoperative radiotherapy was comparable, even in patients with inferior WPOI. Radiotherapy, however, may only benefit patients with IV/V levels of micrometastasis. These data indicated that postoperative radiotherapy is dispensable for only micrometastasis OSCC patients.

Abstract
STUDY OBJECTIVE Evidence suggests that vaccine-type human papillomavirus (HPV) prevalence may decrease in unvaccinated women after HPV vaccine introduction, indicating herd protection. The aim of this study was to determine factors associated with vaccine-type HPV (i.e. absence of herd protection) after vaccine introduction. DESIGN We conducted three cross-sectional studies from 2006-2014 (n = 1180): wave 1 (2006-2007), wave 2 (2009-2010), and wave 3 (2013-2014). SETTING Participants were recruited from a hospital-based teen health center and a community health department. PARTICIPANTS We recruited 13-26 year-old young women; those included in this analysis had not received an HPV vaccine. INTERVENTIONS AND MAIN OUTCOME MEASURES The outcome measure was infection with at least one vaccine-type HPV (HPV6, 11, 16, 18). RESULTS Multivariable logistic regression demonstrated that in wave 1 (before vaccine introduction), history of anal intercourse (OR = 1.8, 95% CI = 1.1-3.0), age 18-21 vs 13-17 years (OR = 2.1, CI = 1.2-3.6), and Black/multiracial vs White race (OR = 1.8, CI = 1.1-3.0) were associated with vaccine-type HPV in unvaccinated women. In wave 2, no variables were associated with HPV. In wave 3, sexually transmitted infection history (OR = 3.6, CI = 1.3-9.7) was associated with HPV. CONCLUSION We did not identify a consistent set of modifiable risk factors associated with vaccine-type HPV after vaccine introduction across the three study waves, underscoring the urgency of vaccination for primary HPV prevention and the limitations of relying on herd protection.

Abstract
Neoseiulus barkeri (HUGHES) is the natural enemy of spider mites, whiteflies and thrips. Screening for chemically-resistant predatory mites is a practical way to balance the contradiction between the pesticide using and biological control. In this study, the number of eggs laid by fenpropathrin-susceptible and resistant strains of N. barkeri was compared. Additionally, we cloned three N. barkeri vitellogenin (Vg) genes and used quantitative real-time polymerase chain reaction to quantify Vg expression in susceptible and resistant strains. The total number of eggs significantly increased in the fenpropathrin-resistant strain. The full-length cDNA cloning of three N. barkeri Vg genes (NbVg1, NbVg2 and NbVg3) revealed that the open reading frames of NbVg1, NbVg2 and NbVg3 were 5571, 5532 and 4728 bp, encoding 1856, 1843 and 1575 amino acids, respectively. The three N. barkeri Vg possessed the Vitellogenin-N domain (or lipoprotein N-terminal domain (LPD_N)), von Willebrand factor type D domain (VWD) and the domain with unknown function 1943 (DUF1943). The NbVg1 and NbVg2 expression levels were significantly higher in the resistant strain than in the susceptible strain, while the NbVg3 expression level was lower in the resistant strain. Thus, we speculate that the increased number of eggs laid by the fenpropathrin-resistant strain of N. barkeri may be a consequence of changes in Vg gene expression.

Abstract
This study aimed to prospectively evaluate the safety and efficacy of a new developed method that uses percutaneous ultrasound-guided hematoma aspiration followed by targeted localized manual compression for treatment of femoral artery pseudoaneurysm after cardiac catheterization, which obviates thrombin use, surgery, and long-time compression.From January 2007 to July 2014, 32 patients (17 women; mean age, 55.3 ± 11.5 years) out of 8,725 consecutive cases undergoing cardiac catheterization via femoral access developed one pseudoaneurysm each ranging in size from 21 × 11 mm to 72 × 39 mm. Under ultrasound guidance, blood within the pseudoaneurysm was aspirated percutaneously using an 18-gauge needle, while the pseudoaneurysm neck and a nearby site over the pseudoaneurysm were manually compressed for 15 min. All patients underwent repeat ultrasound examination 24 hours later.Of the 32 pseudoaneurysms, 31 were successfully occluded, and 1 recurred in a patient with coexisting arteriovenous fistula, yielding an overall success rate of 96.9% (31/32). No further recurrence or procedure related complications were observed. The treatment approach is unlike open surgical repair with hematoma evacuation and arterial defect suturing, in that it entails hematoma aspiration and feeding flow blockage at the pseudoaneurismal neck.In this preliminary experience, combining percutaneous ultrasound-guided hematoma aspiration and manual compression appears safe and effective in treating femoral artery pseudoaneurysms after catheterization and avoids thrombin use, long-time compression, and surgery.
