Authors: Lei Yuxia , Zhang Linkun , Wang Zhengyan , Kong Zhiqiang , Ma Hanru , Liu Xiuhuan 
Published: February 2021

Abstract
Sentiment analysis based on statistics has rapidly developed in deep-learning. Bilateral attention neural network (BANN), especially Bidirectional Encoder Representations from Transformers (BERT), has reached high accuracy. However, with the increase of network depth and large-scale corpus, the computational overhead of BANN increases geometrically. How to reduce training corpus scale has correspondingly become an important research focus. This paper proposes a reduced corpus scale method called Concept-BERT, which consists of the following steps: firstly, using Formal Concept Analysis (FCA), Concept-BERT mines the association rules among corpus and reduces corpus attributes, and hence reducing corpus scale; secondly, reduced-corpus is inputed to BERT and the result is obtained; finally, the attention of Concept-BERT is analyzed. Concept-BERT is experimented for sentiment analysis on CoLA, SST-2, Dianping and Blogsenti, and its accuracy reaches 81.1, 92.9, 77.9 and 86.7 respectively. Our experimental results show that the proposed method has the same accuracy as BERT, using low-scale corpus and low overhead, and low-scale corpus doesn't affect model attention.

Abstract
Natural and artificial selection fix certain genomic regions of reduce heterozygosity which is an initial process in breed development. Primary goal of the current study is to identify these genomic selection signatures under positive selection and harbor genes in Pakistani Kamori goat breed. High throughput whole genome pooled-seq of Kamori (n = 12) and Bezoar (n = 8) was carried out. Raw fastq files were undergone quality checks, trimming and mapping process against ARS1 reference followed by calling variant allele frequencies. Selection sweeps were identified by applying pooled heterozygosity (Hp) and Tajima’s D (TD) on Kamori while regions under divergent selection between Kamori & Bezoar were observed by Fixation Index (FST) analysis. Genome sequencing yielded 619,031,812 reads of which, 616,624,284 were successfully mapped. Total 98,574 autosomal selection signals were detected; 32,838 from Hp and 32,868 from each FST & TD statistics. Annotation of the regions with threshold (-ZHp ≥ 5, TD ≤ -2.72 & FST ≤ 0.09) detected 60 candidate genes. The top hits harbor Chr.1, 6, 8 & 21 having genes associated with body weight (GLIS3, ASTE1), coat color (DOCK8, MIPOL1) & body height (SLC25A21). Other significant windows harbor milk production, wool production, immunity, adaptation and reproduction trait related genes. Current finding highlighted the under-selection genomic regions of Kamori breed and likely to be associated with its vested traits and further useful in breed improvement, and may be also propagated to other undefined goat breeds by adopting targeted breeding policies to improve the genetic potential of this valued species.

Abstract
Background: A range of postoperative complications make femoral neck fracture difficult to treat. Femoral neck shortening and internal fixation failure are two most prevalent complications associated with many surgical strategies. This study evaluates the probability of and risk factors for these complications after the treatment of femoral neck fracture using cannulated screws combined with a medial buttress plate.Methods: Data of 70 patients with femoral neck fractures treated using cannulated screws combined with a medial buttress plate in our hospital between March 2016 and March 2019 were retrospectively analyzed, and 40 patients who were followed up for more than 3 months were enrolled in the study. We evaluated the probability of postoperative femoral neck shortening and internal fixation failure and conducted multivariate logistic regression analysis to determine risk factors.Results: All 40 patients had Garden III/IV or Pauwels II/III fractures. Of these patients, 11 had femoral neck shortening greater than 5 mm and 8 had fracture nonunion or screw cutout requiring reoperation. There were no differences in age, sex, fracture site, Pauwels classification, and reduction quality between the shortening and non-shortening groups; however, there were significant differences in screw quality. Similarly, there were no differences in age, sex, Pauwels classification, reduction quality, and screw quality between the fixation failure and non-failure groups, but there were significant differences in fracture site and shortening. According to the multivariate analyses, screw quality was an independent risk factor for femoral neck shortening (odds ratio [OR]: 8.58; 95% confidence interval [CI]: 1.35–50.57; P=0.022), and femoral neck shortening was an independent risk factor for internal fixation failure (OR: 11.82; 95% CI: 1.66–84.36; P=0.014).Conclusions: Femoral neck fracture treatment using cannulated screws combined with a medial buttress plate led to a femoral neck shortening rate lower than that of other internal fixation methods and an internal fixation failure rate lower than or equivalent to that of other internal fixation methods. The quality of cannulated screws is a risk factor for postoperative shortening of the femoral neck, and femoral neck shortening is a risk factor for postoperative internal fixation failure.

Abstract
Anti-Mullerian hormone (AMH) and testosterone (T) both play distinct roles in the early stages of folliculogenesis. However, the relationship between serum T and AMH levels is poorly understood. This study aimed to investigate the association between serum T and AMH levels in infertile women. A total of 1,935 infertile women aged 20 to 46 years were included in the cross-sectional study and divided into four quartile groups (Q1 to Q4) based on serum T levels. Compared to the subjects in the highest T quartile (Q4), those in the lowest T quartile (Q1) showed significantly lower AMH levels. After adjustment for age, body weight, body mass index and FSH, increasing T quartile categories were associated with higher AMH levels. Binary logistic regression analyses revealed that the odds for the risk of diminished ovarian reserve (DOR) were 11.44-fold higher in Q1 than in Q4 and the odds for the risk of excess ovarian reserve (EOR) were 10.41-fold higher in Q4 than in Q1. Our data show that serum T levels are positively associated with serum AMH levels and suggest that androgen insufficiency may be a potential risk factor for DOR; androgen excess may lead to EOR in infertile women.

Abstract
Purpose. Patients with end-stage renal disease (ESRD) face various physical and mental limitations resulting from different renal replacement therapy (RRT) modalities. Renal transplantation (Tx) is considered as the treatment that impacts most on health-related quality of life (HRQOL). This study aimed to analyze and compare the HRQOL and depression levels of patients undergoing hemodialysis (HD), peritoneal dialysis (PD) and Tx.Methods. A single-center cross-sectional sample of 112 HD patients, 68 PD patients and 97 Tx patients participated in our questionnaire survey. The HRQOL and depression levels were assessed through the 36-Item Short-Form Health Survey (SF-36) and Mental Health Inventory (MHI-5), respectively. The multiple linear regression model was performed to examine the factors associated with each of the HRQOL scale scores. Results. The SF-36 HRQOL of Tx patients differed significantly from that in HD and PD groups in all eight dimensions and two components (all P<0.001). More than 45% of patients in each group were facing depressive symptoms. HD patients (63.4%) and PD (67.6%) patients were more depressive compared with Tx patients (45.4%, P =0.006). Depression in ESRD patients contributed to a worse quality of life (P<0.001). Patients ranging in age from 31 to 50, having full-time jobs, receiving Tx and without depression were associated with better HRQOL in the domain of Physical Component Scores (PCS). Patients with unemployment, dismissal or being looking for a job, receiving Tx and without depression were associated with better HRQOL in the domain of Mental Component Scores (MCS).Conclusions. Tx patients had better HRQOL and less depressive symptoms than HD and PD patients. Depression was related to an impaired HRQOL, which was common in ESRD patients. The severity of depression in ESRD patients and the effectiveness of Tx on HRQOL improvement need to be underscored.

Published: February 2021

Abstract
BackgroundTo examine two different methods for treating patients with a total anomalous pulmonary venous connection (TAPVC) who need emergency surgery and to summarize the effects of the two strategies by retrospectively reviewing the data of 54 patients.MethodsA retrospective review of 54 patients with TAPVC who underwent emergency operations between December 2010 and July 2019 at a single institution was conducted. All patients exhibited respiratory and hemodynamic instability that required mechanical ventilation and inotropic support. Forty-four patients received emergency operations within 24 to 72 hours due to stabilization of the patient’s condition. Stable hemodynamics were achieved, and a constant milieu interne was maintained before the operation. These patients comprised the subemergency operation (SEO) group. Rather than being subjected to efforts to obtain stable hemodynamics and maintain a constant milieu interne, ten patients received emergency operations immediately within 24 hours of diagnosis or an emergency operation is performed immediately due to uncorrectable acidosis or progressive cardiovascular collapse. These patients comprised the emergency operation (EO) group. The hospital course, operative data, and outpatient records were reviewed.ResultsThe median weight, median age at surgery, mean cardiopulmonary bypass (CPB) duration and mean aortic cross-clamp (ACC) duration were not significantly different between the two groups. The median durations of ventilator support were 8.1±4.6 (2-13) days in the SEO group and 4.9±2.1 (2-18) days in the EO group, resulting in a significant difference (p=0.008). There were 12 operative mortalities (27.3%) in the SEO group and 2 operative mortalities (20%) in the EO group, resulting in no significant difference in mortality (p=0.636). Postoperative complications, such as low cardiac output and arrhythmia, were not significantly different between the two groups. The actuarial survival rates in the EO and SEO groups at 5 years were 87.5% and 89.9%, respectively. There was no difference in actuarial survival between the two groups at the latest follow-up (SEO group 89.9% versus EO group 87.5%, p=0.8115).ConclusionRather than making efforts to achieve stable hemodynamics and maintain a constant milieu interne, an emergency operation should be performed immediately, and some efforts to address metabolic acidosis do not reduce mortality.

Abstract
Backgrounds: This study examined the dynamic association between risk communication and public’s risk perception and action across the COVID-19 outbreak timeline in China.Methods: Publicly available information on COVID-19 was collected by Parehub tool for official channels (e.g. government websites and official media), and by Zhongyun Big Data Platform for mainstream Chinese social media (e.g. TikTok, Weibo, etc.). Information was examined by its release channels, content and release time. An online survey was conducted via WeChat across 33 provinces and municipalities of China to assess changes in participants’ risk perception and action against COVID-19. Information content and release-time trajectories were examined against the public’s risk perception and actions over time.Results: Altogether, 1,477 pieces of authorized information and 297,000 pieces of short videos on COVID-19 were retrieved from official channels and social media. Our online survey of 1,311 responds (25-60 years, 42% male) indicated that participants mainly relied on official channels to obtain information. Alongside the progress of the outbreak, there was a gradual rise in information quantity, publishing frequency, and content variation. Correspondingly, the public’s risk perception that “take it seriously" rose from 13% to 80%, 87.1% of who took “multiple actions” compared to 25.9% initially.Conclusions: Our findings indicated that insufficient information freely-accessible at the early stages of the outbreak may nevertheless lead to the lack of risk awareness and inadequate protective actions of the public. Given the current global situation of COVID-19, the study highlights authorized, transparent, and timely two-way risk communication is vital to guide public perception and actions.
Multi-Volume Hemacytometer

Abstract
Cell counting has become an essential method for monitoring the viability and proliferation of cells. A hemacytometer is the standard device used to measure cell numbers in most laboratories which are typically automated to increase throughput. The principle of both manual and automated hemacytometers is to calculate cell numbers with a fixed volume within a set measurement range (105~106 cells/ml). If the cell concentration of the unknown sample is outside the range of the hemacytometer, the sample must be prepared again by increasing or decreasing the cell concentration. We have developed a new hemacytometer that has a multi-volume chamber with 4 different depths containing different volumes (0.1, 0.2, 0.4, 0.8 µl respectively). A multi-volume hemacytometer can measure cell concentration with a maximum of 106 cells/ml to a minimum of 5×103 cells/ml. Compared to a typical hemacytometer with a fixed volume of 0.1 µl, the minimum measurable cell concentration of 5×103 cells/ml on the multi-volume hemacytometer is twenty times lower. Additionally, the Multi-Volume Cell Counting model (cell concentration calculation with the slope value of cell number in multi-chambers) showed a wide measurement range (5×103 ~1×106 cells/ml) while reducing total cell counting numbers by 62.5% compared to a large volume (0.8 µl-chamber) hemacytometer.

Abstract
In this study, bromoacetic acid was reacted with 3-(mercaptopropyl) trimethoxy silane (MPTS) and trimethoxy silyl propyl thioacetic acid (TSTA) was produced. Also, bromoacetic acid was reacted with 3-(triethoxysilyl) propylamine (APTS), and triethoxysilyl propylamino acetic acid (TSPA) was synthesized. Finally, from a reaction between trimellitic anhydride (TMA) and APTS, trimellitylimidopropyl triethoxysilane (TMIS) resulted. In all reactions mentioned above, a carboxylic acid head and a trialkoxy silane tail including reactants were obtained. Furthermore, hybrid coatings based on methacrylated bisphenol A epoxy (MBAE) and synthesized carboxylic acids were obtained by photopolymerization. Polycarbonate substrates were utilized for preparation of transparent hybrid films. Then, the solvent resistance, hardness, gel content as well as the adhesion of coatings were measured as physical and mechanical properties. According to the obtained results, these properties of hybrid coatings improved with the increase in alkoxysilanes and sol–gel precursor contents. The surface morphology was characterized by scanning electron microscopy (SEM). The results showed that silica particles were not dispersed homogenously at the molecular level in the hybrid system. Also, the thermogravimetric analysis results indicated that alkoxysilanes enhanced the thermal oxidative stability of the hybrid coatings.

Abstract
BackgroundToday, with the advancement of science, technology and industry, people's lifestyles such as the pattern of people's food, have changed from traditional foods to fast foods. The aim of this survey was to examine and identify factors influencing intent to use fast foods and behavior of fast food intake among students based on the theory of planned behavior (TPB). MethodsA cross-sectional study was conducted among 229 university students. The study sample was selected and entered to the study using stratified random sampling method. Data were collected using a four-part questionnaire including Participants’ characteristics, knowledge, the TPB variables, and fast food consumption behavior. The study data were analyzed in SPSS software (version 16.0) using descriptive statistics (frequencies, Means, and Standard Deviation) and inferential statistics (t-test, Chi-square, correlation coefficient and multiple regressions).ResultsThe monthly frequency of fast food consumption among students was reported 2.7 times. The TPB explained 35%, 23% variance of intent to use fast food and behavior of fast food intake, respectively. Among the TPB variables, knowledge (r=.340, p<0.001) and subjective norm (r=.318, p<0.001) were known as important predictors of intention to consume fast foods - In addition, based on regression analyses, intention (r=.215, p<0.05), perceived behavioral control (r=.205, p<0.05), and knowledge (r=.127, p<0.05) were related to fast food consumption, and these relationships were statistically significant. ConclusionsThe current study showed that the TPB is a good theory in predicting intent to use fast food and the actual behavior. It is supposed that health educators use from the present study results in designing appropriate interventions to improve nutritional status of students.
