Abstract
Objective: To analyze the effects of hemocoagulase agkistrodon (HCA) on the coagulation status of healthy people and traumatic brain injury (TBI) patients in vitro. Methods: A total of 10 TBI patients were enrolled from December 2018 to June 2019,and 24 age and sex matched healthy controls were also enrolled. Clinical and pathological data, blood samples of all subjects were collected. Different gradient concentrations of HCA were added to the blood samples which were detected by thromboelastography, and the R value, K value, α angle and MA value of thromboelastography parameters between the two groups were analyzed to explore the effect of HCA on the coagulation status of patients with TBI. Results: With the increase of HCA concentration in blood samples, the R and K values gradually increased, and the α angles and MA values gradually decreased in both TBI patients group which included 7 males and 3 females, with an median age of 33 (28-39) years old and healthy control group which included 11 males and 13 females, with an median age of 33 (23-49) years old. The differences in the R values, K values, α angles, and MA values of different concentration gradients were statistically significant in both healthy control group and TBI patients group (χ2 were 109.80, 131.28, 185.47, 165.97 and 54.92, 75.60, 80.12, 59.25, respectively, all P<0.001). The differences between R values after adding HCA of 0-0.105 U/ml in the healthy group were statistically significant (P=0.025), but K values, α angles and MA values were not statistically significant (P values were 0.275, 0.206 and 0.330, respectively); the R values of the TBI patients group were not statistically significant after adding HCA of 0 to 0.105 U/ml (P=0.976), and the K values, α angles, and MA values were statistically significant (P values were 0.047, 0.041, and 0.034, respectively).The R values of the healthy control group, the TBI patients group, and the overall data were significantly positively correlated with the HCA dose (r values were 0.552、0.700、0.420, respectively, P<0.001), the K values were significantly positively correlated with the HCA dose (r values were 0.726、0.861、0.750, respectively, P<0.001), the α angles were significantly negatively correlated with the HCA dose (r values were -0.815、-0.876、-0.807, respectively, P<0.001) and the MA values were significantly negatively correlated with the HCA dose (r values were -0.757、-0.710、-0.729, respectively, P<0.001). Conclusions: HCA does not aggravate the procoagulant state of blood in healthy people and TBI patients, and with the increase of HCA concentration in blood, the blood samples of both groups show a tendency to decrease the coagulation ability.

Abstract
The mechanical properties of cell nuclei have been recognized to reflect and modulate important cell behaviors such as migration and cancer cell malignant tendency. However, these nuclear properties are difficult to characterize accurately using conventional measurement methods, which are often based on probing or deforming local sites over a nuclear region. The corresponding results are sensitive to the measurement position, and they are not decoupled from the cytoplasmic properties. Microfluidics is widely recognized as a promising technique for bioassay and phenotyping. In this report, we develop a simple and nondestructive approach for the single-cell quantification of nuclear elasticity based on microfluidics by considering different deformation levels of a live cell captured along a confining microchannel. We apply two inlet pressure levels to drive the flow of human nasopharyngeal epithelial cells (NP460) and human nasopharyngeal cancerous cells (NPC43) into the microchannels. A model considering the essential intracellular components (cytoplasm and nucleus) for describing the mechanics of a cell deforming along the confining microchannel is used to back-calculate the cytoplasmic and nuclear properties. On the other hand, we also apply a widely used chemical nucleus extraction technique to examine its possible effects (e.g., reduced nuclear modulus and reduced lamin A/C expression). To determine if the decoupled nuclear properties are representative of cancer-related attributes, we classify the NP460 and NPC43 cells using the decoupled physical properties as classification factors, resulting in an accuracy of 79.1% and a cell-type specificity exceeding 74%. It should be mentioned that the cells can be recollected at the device outlet after the nondestructive measurement. Hence, the reported cell elasticity measurement can be combined with downstream genetic and biochemical assays for general cell research and cancer diagnostic applications.

Abstract
OBJECTIVE Pre-eclampsia (PE) is a pregnancy-associated condition initiated by placental factors. We have demonstrated that placental extracellular vesicles (pcEVs) cause hypertension and proteinuria in pregnant and non-pregnant mice. STUDY DESIGN An observational study with both case-control and longitudinal designs. SETTING A single centre at the Department of Obstetrics and Gynaecology, Tianjin Medical University. POPULATION We collected blood samples and clinical information from 54 PE patients, 33 normally pregnant women at 30-36 gestational weeks and on postpartum days 1 and 4 for the cross-sectional study, and at 22-31, 32-35 and 36-40 weeks for the longitudinal study. Non-pregnant women were also recruited. METHODS Blood samples were analysed using flow cytometry, coagulation tests and ELISA. MAIN OUTCOME MEASURES The primary outcome was plasma pcEV and other extracellular vesicles (EVs), and their expressions of anionic phospholipids and von Willebrand factor (VWF). Secondary variables included coagulation, ADAMTS-13 and the anionic phospholipid-binding proteins. RESULTS Plasma pcEVs progressively increased from pregnant women during non-menstrual period (NW) to PE patients (interquartile range [IQR] for NW: 206/microlitre [116-255], normal pregnancy [NP]: 1108/microlitre [789-1969] and PE: 8487/microlitre [4991-16 752]) and predicted PE. EVs from endothelial cells, platelets and erythrocytes accounted for <10% of pcEVs. VWF became hyper-adhesive in PE patients and contributed to the pregnancy-associated hypercoagulability. CONCLUSION Placental, platelet- and endothelial cell-derived EVs were significantly elevated in PE patients, but only pcEVs predicted PE. These EVs played a causal role in the pregnancy-induced hypercoagulability. TWEETABLE ABSTRACT Placenta-derived extracellular vesicles predict pre-eclampsia and the associated hypercoagulability.

Abstract
Abstract
Background
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease characterized by fibrofatty replacement of the myocardium and ventricular arrhythmias. Biventricular (BiV) involvement in ARVC may lead to heart failure.
Purpose
This study aimed to investigate the role of novel plasma biomarkers soluble (s)ST2, Galectin-3 (Gal-3) and GDF-15 in predicting BiV involvement and adverse outcomes in ARVC patients.
Methods
ARVC patients from two independent cohorts were studied. 108 patients were included from the discovery cohort and 47 patients were included from a second validation cohort. All patients had a definite ARVC diagnosis at time of blood withdrawal. sST2, Gal-3 and GDF-15 were independently correlated with NT-proBNP, left ventricular (LV) ejection fraction, late gadolinium enhancement by cardiac magnetic resonance (CMR) imaging and clinical outcome.
Results
ARVC patients with LV involvement had higher levels of sST2 and GDF-15 as compared to controls and patients with isolated right ventricular involvement. sST2 and GDF-15 significantly correlated to late gadolinium enhancement on CMR and also correlated to adverse heart failure outcomes. Gal-3 was elevated in ARVC patients with and without LV involvement as compared to controls. The combined use of the three biomarkers (NT-proBNP, sST2 and GDF-15) showed the best performance in predicting LV involvement in both the discovery and the validation cohort. Plasma drawn from coronary arteries and coronary sinus showed a transmyocardial elevation of sST2.
Conclusion
Our study shows that sST2 and GDF-15 may predict BiV involvement and the combined use of NT-proBNP, sST2 and GDF-15 shows the best prediction of LV involvement in ARVC. Transmyocardial elevation of sST2 suggests that this biomarker is produced by myocardial tissue in ARVC.

Abstract
Objective: To evaluate the efficacy of 23 valent pneumococcal polysaccharide vaccine (PPV23) inoculation against community-acquired pneumonia (CAP) among the elderly aged 60 years old and above in Shanghai. Methods: A prospective cohort study was conducted using a stratified random sampling from October 2013, in which 1 214 and 2 387 elderly people aged 60 and above were selected as the inoculation group and control group, respectively. And a unified questionnaire was used to investigate the basic information of the subjects in the inoculation group and the control group. From October 2013 to December 2018, the subjects were followed up at home or by telephone for a total of 20 times, mainly for whether they had CAP during the observation period. Multivariate logistic regression model was used to calculate RR and 95%CI of CAP incidence between inoculation group and control group for comparing. Results: There were 556 males (45.8%) in the inoculation group and 1 012 males (42.4%) in the control group. And the incidence density of CAP in the inoculation group was lower than that of the control group (0.848/100 person-years vs. 1.452/100 person-years), and the vaccine protection rate was 41.6%, with a statistically significant difference [RR (95%CI)= 0.584 (0.428-0.790), P<0.001]. After adjusting for age, RR (95%CI) was 0.699 (0.507-0.956), and the difference was still statistically significant (P=0.025).Further stratified analysis showed that the vaccine protective rates of PPV23 in the 60-69 year-old group, the 70-79 year-old group and the ≥80 year-old group were 36.7%, 21.6% and 26.0%, respectively, but only in the 60-69 year-old group showed statistical difference (RR=0.633, 95%CI=0.399-0.990, P=0.045). Conclusion: To a certain extent, the incidence of CAP can be reduced by inoculation of PPV23 in elderly population aged 60 and above in Shanghai, and it should be further recommended in elderly population of low age.

Abstract
Objective: To understand the project personnel's attitude towards the 23-valent pneumococcal polysaccharide vaccination program for the elderly in Shanghai and its conversion to routine vaccination and to explore its influential factors, so as to provide reference for the further development of the program. Methods: In 2016, a one-to-one questionnaire survey was conducted among the people involved in the project in the 9 districts of Shanghai and the data of demographic characteristics, cognition of pneumococcal pneumonia and PPV23, evaluation of the project, support rate of the project and its conversion to routine vaccination of the project personnel were collected. Results: Among the 2005 respondents, 28.6% (574 persons) of them were male, 85.5% (1 714 persons) of them supported the free vaccination for the elderly, and 69.5% of them (1 394 persons) supported the routine vaccination. For the 23-valent pneumococcal polysaccharide vaccination program, people under 55 years old, in Qingpu District, with poor cognition of pneumonia and 23-valent pneumococcal polysaccharide vaccine (PPV23) or having lower evaluation of the project's scientificity or enforceability had lower support rate than others, and the OR (95%CI) were 0.38 (0.19-0.75), 0.21 (0.10-0.43), 0.16 (0.06-0.41) and 0.26 (0.10-0.69). People believing that the elderly were susceptible to pneumococcal pneumonia and PPV23 was safe and reliable, and those who were willing to vaccinate the elderly at home had higher support rate, and the OR (95%CI) were 2.30 (1.18-4.47), 2.84 (1.62-4.69) and 5.60 (3.74-8.38). For the program's conversion to routine vaccination, people under 35 years old, in Qingpu District, in the vaccination clinic, and those believing that the project was not scientific and difficult to implement had low support rate, and the OR (95%CI) were 0.56 (0.32-0.98), 0.48 (0.26-0.89), 0.26 (0.12-0.59), 0.58 (0.42-0.79) and 0.50 (0.30-0.81); people with technical secondary school or senior school, in Jiading, Putuo or Minhang District, believing that PPV23 was effective in the prevention of pneumococcal pneumonia in the elderly, and those who were willing to vaccinate the elderly with PPV23 had higher support rate, and the OR (95%CI) were 1.63 (1.11-2.39), 2.28 (1.71-3.03), 1.69 (1.25-2.28) and 4.10 (2.86-5.88). Conclusion: The support rate of pneumococcal vaccination project for the elderly in Shanghai needs to be improved, especially its conversion to the routine vaccination.

Objective: To evaluate the safety of 23 Valent Pneumococcal Polysaccharide Vaccine (PPV23) among eldly people aged 60 and above in Shanghai. Methods: A total of 1 310 660 monitoring data of adverse events following immunization (AEFI) of PPV23 among people aged 60 and above were collected through the National AEFI Surveillance System from September 14, 2013 to December 31, 2017 in Shanghai. And the descriptive epidemiological methods were used for analysis. Results: 433 cases of AEFI were reported from September 14, 2013 to December 31, 2017, with the incidence rate of AEFI was 33.04/100 000 doses. The general reactions were reported as 392 cases (90.53%), with 17 cases of abnormal reactions (3.93%), 23 cases of coincidences (5.31%) and 1 case of psychogenic reactions (0.23%). The reported incidence rates of general reactions and abnormal reactions of free PPV23 inoculation among elderly people in urban areas were 41.31 per 100 000 doses and 1.91/100 000 doses, respectively, which were higher than those in suburban areas (24.18/100 000 doses, 1.32/100 000 doses) and exurban areas (27.84/100 000 doses, 0.59/100 000 doses). The reported incidence rate of general reaction in females (35.38/100 000 doses) was higher than that in males (24.06/100 000 doses), and the reported incidence rate of abnormal reaction in males (1.58/100 000 doses) was higher than that in females (1.03/100 000 doses). The reported incidence rates of general and abnormal reactions were the highest in 60-64 years old group (62.65/100 000 doses and 4.87/100 000 doses, respectively). In addition, all patients with general reactions or abnormal reactions were better or cured. Conclusion: PPV23 vaccination is safe among people aged 60 and above in Shanghai.

Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.

Abstract
OBJECTIVE To investigate the association between body mass index (BMI) and ectopic pregnancy (EP) following embryo transfer (ET). DESIGN Retrospective cohort study. SETTING University-affiliated hospital. POPULATION A total of 16 378 pregnancies derived from either fresh ET or frozen-thawed ET between January 2008 and December 2017. METHODS We used the generalised estimating equation (GEE) to analyse the association between BMI categories and EP, as one woman may contribute to more than one pregnancy. Generalised additive models were also used to demonstrate the non-linear association. Models were adjusted for age, parity, gravidity, previous history of ectopic pregnancy, duration of infertility, polycystic ovary syndrome, endometriosis, diagnosis of tubal problems, ovarian reserve markers, ovarian stimulation parameters, insemination protocol, endometrial thickness and embryo transfer policies. MAIN OUTCOME MEASURES Ectopic pregnancy. RESULTS According to the WHO criteria, the number of cycles with low (<18.5 kg/m2 ), normal (18.5-24.9 kg/m2 ) and high (≥25 kg/m2 ) BMI were 2155, 13 447 and 776, respectively. In comparison with the normal BMI group, the rate of EP was significantly increased in the low BMI group (2.92% versus 2.02%, relative risk 1.45, 95% CI 1.11-1.90), but not in the high BMI group (2.84%, relative risk 1.41, 95% CI 0.92-2.20). Adjusted for confounding factors, the odds ratio for EP comparing low BMI versus normal BMI was 1.61 (95% CI 1.19-2.16) and that comparing high BMI versus normal BMI was 1.12 (95% CI 0.72-1.76). CONCLUSIONS Low BMI is associated with an increased risk of EP. TWEETABLE ABSTRACT The ectopic pregnancy rate after embryo transfer for lean women is higher than that for women of normal weight.

Abstract
Objective: To explore the influence of lateral patellofemoral joint degeneration on the treatment of anteromedial osteoarthritis of knee joint by Oxford medial unicompartmental knee arthroplasty. Methods: The clinical data of 73 patients (73 knees) with knee osteoarthritis underwent unicompartmental knee arthroplasty at Department of Orthopaedic Surgery, Xuanwu Hospital, Capital Medical University from March 2016 to December 2017 were analysed respectively.There were 18 males and 55 females, aged (68.6±7.5) years(range: 53 to 89 years).The lateral patellofemoral joints of patients were evaluated by Ahlback grading system. Patients with Ahlback 0 andⅠ were in the non degenerative group (37 cases), and those with Ahlback Ⅱ and above were in the degenerative group (36 cases). Hospital for special surgery knee score(HSS) and the Western Ontario and McMaster Universities(WOMAC) osteoarthritis index, as well as the condition of kneeling, sit to stand movement, up stair and down stair were recorded. The data before and after operation were compared by paired sample t test, and the data between groups were compared by independent sample t test. χ(2) test was used for counting data. Pearson correlation analysis was used to compare the correlation between ahlback score, HSS and WOMAC osteoarthritis index. Results: The follow-up time was (35.1±6.6) months (range: 25 to 47 months).The knee function of the patients improved significantly after operation.The HSS score increased from 57.7±11.8 preoperative to 81.8±7.8 postoperative (t=16.64, P=0.00) and WOMAC osteoarthritis index decreased from 48.9±13.4 preoperative to 15.6±8.8 postoperative (t=20.48, P=0.00). There was no statistical difference in the change of HSS between the degenerative group and the non-degenerative group before and after surgery(27.5±12.2 vs. 22.5±12.3, t=-1.65, P=0.10) as well as the change of WOMAC osteoarthritis index(31.8±14.0 vs. 36.4±13.7, t=-1.35, P=0.18), but the lateral patellofemoral joint degeneration was related to inability to complete squats (χ(2)=5.17, P=0.04) and sitting up (χ(2)=7.22, P=0.01). Conclusion: The degeneration of lateral patellofemoral joint has no effect on the early functional recovery of patients with anteromedial knee osteoarthritis after Oxford medial unicompartmental knee arthroplasty.

Abstract
We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m_{V}) from 10 to 300 eV/c^{2} in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m_{V} from 0.1 to 4.0 keV/c^{2} are set from 449.6 kg-day data, with a minimum of κ=1.3×10^{-15} at m_{V}=200 eV/c^{2}.

Abstract
Cell isolation from blood is an important process for diagnosing immune diseases. There are still demands for a user-friendly approach to achieve high cell extraction efficiency and purity of a target immune cell subtype for more promising diagnosis and monitoring. For selective immune cell isolation, we developed a microstructured device, which consists of antibody-coated micropillars and micro-sieve arrays, for isolating a target immune cell subtype from bovine blood samples. The focusing micropillars can guide immune cells flowing to the subsequent micro-sieves based on deterministic lateral shifts of the cells. The arrangement of these microstructures is characterized and configured for the maximal cell capture rate. Surface modification with a selected antibody offers selective cell capture in the micro-sieves based on the antigen-antibody reaction. We prepare a cell mixture of human CD14-expressing leukemia cells (THP-1) and epithelial cells (MDA-MB-231) in diluted blood to characterize the cell isolation operation, with a selective cell isolation yield of >80%, cell purity of ∼100% and cell viability of >93%. Together, this microstructured device strategy can achieve high-yield selective isolation of immune cells from blood samples and support downstream genetic and biochemical cell analyses, contributing to the medical diagnosis of a broad range of immune diseases.

Abstract
Growth and fatness traits are complex and economically important traits in the pig industry. The molecular basis underlying porcine growth and fatness traits remains largely unknown. To uncover genetic loci and candidate genes for these traits, we explored the GeneSeek GGP Porcine 80K SNP chip to perform a GWAS for seven growth and fatness traits in 365 individuals from the Sujiang pig, a recently developed breed in China. We identified two, 17, one and 11 SNPs surpassing the suggestively significant threshold (P < 1.86 × 10-5 ) for body weight, chest circumference, chest width and backfat thickness respectively. Of these SNPs, 20 represent novel genetic loci, and five and four SNPs were respectively associated with chest circumference and backfat thickness at a genome-wide significant threshold (P < 9.31 × 10-7 ). Eight SNPs had a pleiotropic effect on both chest circumference and backfat thickness. The most remarkable locus resided in a region between 72.95 and 76.27 Mb on pig chromosome 4, harboring a number of previously reported quantitative trait loci related to backfat deposition. In addition to two reported genes (PLAG1 and TAS2R38), we identified four genes including GABRB3, ZNF106, XKR4 and MGAM as novel candidates for body weight and backfat thickness at the mapped loci. Our findings provide insights into the genetic architecture of porcine growth and fatness traits and potential markers for selective breeding of Chinese Sujiang pigs.
