Abstract
Constrictive pericarditis though an uncommon diagnosis is a potentially reversible form of heart failure (with surgical pericardiectomy) and hence is imperative to diagnose. Diagnosis is dependent on a high index of clinical suspicion and further testing with appropriate cardiac investigations including cardiac imaging with invasive cardiac catheterisation as the gold standard.

Abstract
Funding Acknowledgements

Background
Young adults with mildly elevated blood pressure are less likely to engage with physical activity. This may be because early hypertension alters myocardial response to moderate exercise, leading to greater perceived exertion and lower levels of enjoyment. As atrial and ventricular function are closely coupled we investigated whether subclinical atrial changes at rest may identify this myocardial response.
Purpose
To identify whether subclinical changes in left atrial function at rest predict response to exercise by performing left atrial deep-phenotyping in a cohort of young adults with a range of blood pressures.
Methods
Seventy-one full-term born young adults (25.25 ± 5.13 years) were enrolled in the Young Adult Cardiovascular Health sTudy (YACHT) to undergo baseline clinical and cardiovascular phenotyping including detailed blood pressure measurement. Cardiopulmonary exercise testing combined with echocardiography imaging was performed to assess the myocardial response to physical exercise at 40%, 60% and 80% of peak exercise load for all participants. Left ventricular ejection fraction and global longitudinal strain were measured from an apical four chamber view at each exercise load, and resting left atrial phasic function was assessed by conventional and speckle tracking echocardiography from apical four and two chamber views (figure 1).
Results
In this young cohort with a range of blood pressure (120.9 ± 12.96/70.85 ± 9.78 mmHg), resting left atrial reservoir and conduit function, but not left atrial structural measures, showed good correlation with left ventricular ejection fraction and global longitudinal strain during 40%, 60% and 80% of peak exercise. The association between resting left atrial conduit with left ventricular deformation at 60% of peak exercise intensity remained significant when adjusted for age, sex and mean arterial pressure (P = 0.007).
Conclusion
Left atrial phasic function at rest predicts left ventricular responses to physical exercise in this cohort of young adults, which may relate to early subclinical left atrial remodelling in early hypertension. These findings require validation in other cohorts and investigation of whether this exercise limitation can be overcome in young hypertensives.

Abstract
In this paper, a splitting ratio-adjustable Mach-Zehnder interferometer (MZI) for the measurement of relative humidity (RH) is proposed and experimentally demonstrated. The sensing head contains three sections of single mode fiber (SMF) and two sections of multimode fiber (MMF), in which the two MMFs are spliced among the three SMFs. The MMFs are corroded with hydrofluoric acid and act as mode couplers to split and recombine light owing to the core diameter mismatch with the SMF. A layer of graphene oxide (GO) is coated on the MMFs by dip-coating and natural evaporation. The effective refractive index of the GO will vary when it absorbs the water molecules. As a result, the intensity of the transmission light in the core and cladding of the single mode fiber can be adjusted. Thus, the intensity of the resonant dip will vary when the relative humidity changes. The experimental results show that a humidity sensitivity of 0.263 dB/RH% with a linear correlation coefficient of 99% can be achieved in a relative humidity range of 35% to 85%.

Abstract
Objective: To investigate the influence of conventional preoperative intestinal preparation and unplanned preparation on the visual field of pelvic organ prolapse repair surgery. Methods: The patients who underwent transvaginal pelvic organ prolapse repair surgery in Peking University People's Hospital from September 2017 to July 2018 were selected as the research objects except those who had undergone colorectal surgery and chronic constipation. The surgery doctor was blinded by intestinal preparation. There was no intestinal preparation in non intestinal preparation group and polyethylene glycol was taken orally in intestinal preparation group. The main outcome measures were the effect of intestinal contents on the surgical field, the presence of fecal leakage, and the nature and volume of fecal leakage. The standard of fecal contamination was: mild, less than 15 ml, moderate, 15-30 ml, and severe, >30 ml. Secondary indicators were patient satisfaction and symptoms of routine bowel preparation. Results: A total of 120 patients (60 cases of non intestinal preparation group, 60 cases of intestinal preparation group) were selected, including transvaginal hysterectomy, vaginal anterior or posterior colporrhaphy (some patients with anterior prolapse repair with mesh), sacrospinal ligament suspension, total colpectomy and colpocleisis, laparoscopic sacral colpopexy, anti-incontinence surgery. The median age of the patients in non intestinal preparation group was 62 years, and the median age of intestinal preparation group was 60 years. There were no significant differences in median age, anesthesia, operation method, blood loss, operation time and perioperative infection between the two groups (all P>0.05). Fecal contamination occurred in 10% (6/60) of the patients without intestinal preparation and 32% (19/60) of the patients with intestinal preparation (P=0.042). Comparing the two groups, 10% (6/60) of the patients with intestinal preparation had moderate and severe contamination, and the patients without intestinal preparation was only 2% (1/60), there was significant difference (P=0.017). In intestinal preparation group, nausea (8%, 5/60), vomiting (5%, 3/60), abdominal distension (22%, 13/60), fatigue (5%, 3/60) and palpitation (2%, 1/60) were higher than those in non intestinal preparation group. Conclusions: Intestinal preparation with oral laxatives before pelvic organ prolapse repair surgery is not beneficial to the cleaning of the surgical field and increases the discomfort of intestinal preparation. It is safe and feasible for most patients with pelvic organ prolapse to perform pelvic organ prolapse repair surgery without intestinal preparation.

Abstract
Abstract
Aim
This study aimed to develop a nomogram based on clinicopathological features to evaluate the recurrence probability of breast phyllodes tumors following surgery. The criteria for atypia, mitoses, overgrowth, and surgical margin (AMOS) were also validated.
Method
Data from 334 patients with breast phyllodes tumors, who underwent surgical treatment at Sun Yat-sen Memorial Hospital from January 2005 to December 2014, were used to develop a prediction model. Additionally, data of 36 patients from Peking University Shenzhen Hospital and data of 140 patients from Sun Yat-sen University Cancer Center during the same period were used to validate the model. The medical records and tumor slides were retrospectively reviewed. The log-rank and Cox regression tests were used to develop a clinical prediction model of breast phyllodes tumors as well as validating the AMOS criteriaAll statistical analyses were performed using R and STATA.
Results
Of all 334 patients included in the study, 224 had benign, 91 had borderline, and 19 had malignant tumors. The local and distant recurrence rate was 17.7%. The 1-,3-, and 5-year cumulative recurrence-free survival was 98.5%, 97.9%, and 96.8%, respectively. Surgical margin, mitoses, and tumor border were identified as independent risk factors for breast phyllodes tumors. A nomogram was developed based on these three variables. The C-index of internal and external validation was 0.71and 0.67, respectively. The area under the curve of AMOS criteria was 0.59.
Conclusions
The present study model presented a more concise and objective variables to evaluate the recurrence-free survival of patients after surgery compared with that using the AMOS criteria, which is more appropriate for clinical practice and also allows for a more accurate prediction.

Abstract
OBJECTIVE The study aimed to identify the factors associated with the sexual lives of perimenopausal and postmenopausal women in China. METHODS A total of 426 participants were approached about this study from May 2012 to August 2013. In total, 252 cases were included in this study. One hundred and ninety-seven women who filled out the Quality of Sexual Life Questionnaire for Women (QSLQW) and the modified Kupperman Menopausal Index (KMI) had an active sexual life. Pearson's coefficient index was used to determine the correlation between the KMI and different domains of the QSLQW. Multivariable statistical analysis was performed to determine the correlation between different factors and the sexual life of perimenopausal and postmenopausal women. RESULTS When the participants reported a higher KMI, they suffered lower sexual satisfaction (r = -0.16, p = 0.035), more severe sexual anxiety (r = -0.367, p = 4.9 × 10-7), and less sexual response (r = -0.21, p = 0.004). No correlation was found between the KMI and sexual communication, sexual attitude, and self-image. Multivariable statistical analysis showed that menopause status and higher KMI scores are associated with a decrease in sexual satisfaction among Chinese women (β = -9.76, 95% CI -16.89 to -2.64 and β = -0.41, 95% CI -0.68 to -0.15, respectively), and that the better the spousal relationship, the fewer deliveries and the higher the scores of sexual life quality (β = 8.86, 95% CI -0.91 to 18.63 and β = -6.65, 95% CI -11.83 to -1.48, respectively). CONCLUSION Factors including parity, spousal relationship, menopausal status, and menopausal symptoms are associated with the quality of sexual life of perimenopausal and postmenopausal women in China.

Abstract
OBJECTIVES Prediction of embolic events (EEs) in infective endocarditis (IE) could inform clinical decisions, such as surgical timing. We conducted a systematic review to more precisely define associations between risk factors and EEs. METHODS We searched two bibliographic databases (1994-2018) for observational studies that reported EEs in IE patients and considered clinical, microbiological or echocardiographic risk factors. Studies that did not use Duke criteria or only investigated a subset of IE patients were excluded. Study quality was assessed using the Newcastle-Ottawa scale. A pooled risk ratio (RR) for each risk factor was estimated using random-effects models; statistical heterogeneity was estimated using I2. RESULTS Of 3862 unique citations, 47 cohort studies (11 215 IE cases) were included; 54 risk factors were analysed in at least two studies, with nine studies reporting other individual factors. Most studies were of high methodological quality. Major predictors of EEs were intravenous drug use (RR 1.69, 95% CI 1.32-2.17; I2 = 46%), Staphylococcus aureus infection (RR 1.64, 95% CI 1.45-1.86, I2 = 32%), mitral valve vegetation (RR 1.24, 95% CI 1.11-1.37, I2 = 30%), and vegetation size >10 mm (RR 1.87, 95% CI 1.57-2.21, I2 = 48%). EE risk was also higher with human immunodeficiency virus, chronic liver disease, elevated C-reactive protein, Staphylococcus spp. infection, vegetation presence, and multiple, mobile or prosthetic mechanical valve vegetation, and lower with Streptococcus spp. infection. Most findings were unchanged in sensitivity analyses that removed studies with pulmonary EEs from the outcome. CONCLUSIONS Given the serious consequences of embolism, surgical evaluation may be considered in patients with these risk factors.

Abstract
BACKGROUND Little research exists in the teaching of evidence-based dentistry (EBD) to students in the fields of dental hygiene, dental nursing and orthodontic therapy. This study aims to analyse the effect of a 1-day EBD programme on knowledge and confidence whilst also gaining insight into students' experience of the intervention. METHOD A mixed methods study was utilised with explanatory sequential design. The population consisted of dental hygiene (DH), dental nursing (DN) and orthodontic therapy (OT) students (N = 44). The intervention consisted of a 1-day active learning EBD programme, delivered via group projects and lectures. In the initial quantitative phase, a standardised questionnaire pre- and post -intervention measured changes in confidence for all participants, whilst change in knowledge was measured for DH and OT students only. Following this, focus groups were scheduled for all members of each discipline 3 months post-intervention for DN and 2 months post-intervention for DH and OT students. Semi-structured focus group schedules were drawn up, and groups organised according to the outcomes of quantitative data analysis. Qualitative results were analysed using a deductive adaptation of Burnard's thematic content analysis. RESULTS Forty-two students took part (94.45%) in this study. Median knowledge scores increased from zero to two of five (P < .001), whilst median confidence score doubled from four to eight of eight (P < .001). Results of thematic content analysis were coincident with quantitative results; however, it also provided constructive feedback regarding design and content of the course. CONCLUSIONS A 1-day bespoke programme in EBD increased students' confidence and knowledge in EBD skills. However, the findings further suggest that two successive half-day training sessions instead of one full-day training, tied in with coursework that requires the application of the acquired skills, may increase the learning experience further.

Abstract
BACKGROUND Atopic dermatitis (AD) is a skin disease that carries a major health burden, but the exact mechanism of the disease is not yet known. AIM To identify the key genes and micro (mi)RNAs in AD, and to explore their potential molecular mechanisms. METHODS From the Gene Expression Omnibus (GEO) database, we downloaded microarray data for GSE32924 (mRNA profile) and GSE31408 (miRNA profile), which were analysed using GEO2R. Functional and pathway enrichment analyses were performed using the DAVID database, and the protein-protein interaction network was constructed with Cytoscape software. In addition, targets of differentially expressed miRNAs (DEMs) were predicted by the online resource miRDB. RESULTS In total, 328 differentially expressed genes (DEGs) were identified, including 121 upregulated and 207 downregulated genes. Gene Ontology analyses showed that upregulated genes were significantly enriched in immune responses, while downregulated genes were mainly involved in epidermis development. In addition, we identified three DEMs, all of which were downregulated. Hsa-let-7a-5p may target CCR7, and hsa-miR-26a-5p probably targets HAS3. CONCLUSIONS We identified lists of DEGs and DEMs in AD. Bioinformatics and interaction analysis may provide new clues for further studies of AD.

Abstract
This study fabricated and demonstrated a functional, stable electrode structure for a high capacity Li-ion battery (LIB) anode. Effective performance is assessed in terms of reversible lithiation for a significant number of charge–discharge cycles to 80% of initial capacity. The materials selected for this study are silicon and tin and are co-deposited using an advanced manufacturing technique (plasma-enhanced chemical vapour deposition), shown to be a scalable process that can facilitate film growth on 3D substrates. Uniform and hybrid crystalline–amorphous Si nanowire (SiNW) growth is achieved via a vapour–liquid–solid mechanism using a Sn metal catalyst. SiNWs of less than 300 nm diameter are known to be less susceptible to fracture and when grown this way have direct electrical conductivity to the current collector, with sufficient room for expansion. Electrochemical characterisation shows stable cycling at capacities of 1400 mA h g−1 (>4 × the capacity limit of graphite). This hybrid system demonstrates promising electrochemical performance, can be grown at large scale and has also been successfully grown on flexible carbon paper current collectors. These findings will have impact on the development of flexible batteries and wearable energy storage. This study fabricated and demonstrated a functional, stable electrode structure for a high capacity Li-ion battery (LIB) anode.![]()

Abstract
OBJECTIVE Although the frontolimbic cortex has been implicated in borderline personality disorder (BPD), information about possible asymmetries in this region in patients with BPD is limited. This study aimed to examine whether frontolimbic cortex asymmetries differ between patients with BPD and healthy individuals. METHODS The brains of 30 young adult patients with BPD and 32 healthy control subjects were scanned with magnetic resonance imaging (MRI). The participants completed self-report scales assessing impulsivity, affect intensity and other psychological variables. Gray matter volume, surface area, and cortical thickness in regions of interest (ROIs), namely anterior insula (AI) and anterior cingulate cortex (ACC) were determined and the data were probed for hemisphere-group interactions. RESULTS Relative to controls, patients with BPD had reduced cortical thickness in left ACC and less surface area and gray matter volume in left AI. Significant group-hemisphere interactions were observed for gray matter volume and surface area of AI and for cortical thickness of ACC. Post hoc analysis showed that the BPD patients had greater frontolimbic cortex asymmetry than healthy controls; furthermore, greater asymmetry of AI&ACC correlated with a higher score in attention subscale of Barratt Impulsiveness Scale. CONCLUSION Patients with BPD have greater frontolimbic asymmetry than healthy individuals.

Abstract
Extracellular matrix protein 1 (ECM1) is related to strong invasiveness and poor prognosis in major malignancies, but the underlying mechanism remains unknown. Here we aimed to elucidate the function of ECM1 on cell metastasis and glucose metabolism in gastric cancer (GC). The level of ECM1 in sera and tissues of patient with GC were positively correlated with tumor invasion and recurrence. Genetic manipulation of ECM1 expression affected cell metastasis and glucose metabolism in GC cell lines. Enhanced ECM1 expression facilitated gene expression levels associated with epithelial-mesenchymal transition (EMT) and glucose metabolism. Interestingly, our results indicated that ECM1 directly interacted with integrin β4 (ITGB4) and activated ITGB4/focal adhesion kinase (FAK)/glycogen synthase kinase 3β signaling pathway, which further induced the expression of transcription factor SOX2. Aberrant expression of SOX2 altered gene expression of EMT factors and glucose metabolism enzymes. Furthermore, SOX2 enhanced hypoxia-inducible factor α (HIF-1α) promoter activity to regulate glucose metabolism. The micro-positron emission tomography/computed tomography imaging of xenograft model showed that ECM1 substantially increased 18F-fluorodeoxyglucose uptake in xenograft tumors. Using in vivo mouse tail vein injection experiments, ECM1 was also found to increase in lung surface metastasis. These findings provide evidence that ECM1 regulates GC cell metastasis and glucose metabolism by inducing ITGB4/FAK/SOX2/HIF-1α signal pathway and have important implications for the development of therapeutic target to prevent tumor metastasis and recurrence.

Abstract
Nowadays esophageal squamous cell carcinoma (ESCC) is primarily treated by a comprehensive approach combining surgical resection and neoadjuvant chemo- or radiotherapy. However, ESCC is resistant to radiation therapy, resulting in its invasion, infiltration, and metastasis. It usually has rapidly progressed and has a poor outcome clinically. The purpose of this study is to determine the potential radiosensitizing effect of astaxanthin (ATX) and explore the underlying mechanisms in ESCC cells in vitro. ESCC cell lines were exposure to irradiation, in the presence or absence of ATX treatment. Cell viability and radiosensitization were tested by CCK8 assay and clonogenic survival assay, respectively. Cell apoptosis and the changes of cell cycle distribution were observed by flow cytometry. The protein expression of Bcl2, Bax, CyclinB1, and Cdc2 was examined by western blot analysis. It was shown that ATX improved radiosensitivity of ESCC cells and induced apoptosis and G2/M arrest via inhibiting Bcl2, CyclinB1, Cdc2, and promoting Bax expression. In conclusion, ATX might function as a promising radiosensitizer in ESCC cells by leading to apoptosis and G2/M arrest.
