Abstract
The avian adeno-associated virus (AAAV) is a replication-defective nonpathogenic virus that has been proved to be useful as a viral vector in gene delivery. In this study, the feasibility of AAAV for transgenic expression of duck hepatitis A virus (DHAV) VP3 structural protein and its ability to induce protective immunity in ducklings was assessed. The recombinant AAAV (rAAAV-VP3) expressing the VP3 protein was prepared by co-infection of Sf9 cells with recombinant baculovirus (rBac-VP3) containing VP3 gene flanked by inverted terminal repeats (ITRs) of AAAV and the other two recombinant baculovirus expressing AAAV functional and structural genes, respectively. The generation of rAAAV-VP3 was demonstrated by electron microscopy, immunofluorescence assay, and western blot analysis. One day old ducklings were inoculated with rAAAV-VP3 or commercial attenuated vaccine and then challenged with DHAV-1 strain SH two weeks post vaccination. Anti-DHAV-1 antibodies were detected in all vaccinated groups by ELISA, and the titers between the rAAAV-VP3 group and the attenuated vaccine group were not statistically significant. Real time RT-PCR analysis showed that the virus copy numbers in the livers of the PBS control group were significantly higher than that of the rAAAV-VP3 and attenuated vaccine groups. In conclusion, we demonstrated that the VP3 expression mediated by rAAAV in ducklings could induce protective immunity against DHAV challenge, and this could be a candidate vaccine for the control of duck viral hepatitis. Keywords: avian adeno-associated virus; duck hepatitis A virus; VP3 gene; immunogenicity.

Abstract
We conducted an electronic health record (EHR)-based phenome-wide association study (PheWAS) to discover pleiotropic effects of variants in three lipoprotein metabolism genes PCSK9, APOB, and LDLR. Using high-density genotype data, we tested the associations of variants in the three genes with 1232 EHR-derived binary phecodes in 51,700 European-ancestry (EA) individuals and 585 phecodes in 10,276 African-ancestry (AA) individuals; 457 PCSK9, 730 APOB, and 720 LDLR variants were filtered by imputation quality (r 2 > 0.4), minor allele frequency (>1%), linkage disequilibrium (r 2 < 0.3), and association with LDL-C levels, yielding a set of two PCSK9, three APOB, and five LDLR variants in EA but no variants in AA. Cases and controls were defined for each phecode using the PheWAS package in R. Logistic regression assuming an additive genetic model was used with adjustment for age, sex, and the first two principal components. Significant associations were tested in additional cohorts from Vanderbilt University (n = 29,713), the Marshfield Clinic Personalized Medicine Research Project (n = 9562), and UK Biobank (n = 408,455). We identified one PCSK9, two APOB, and two LDLR variants significantly associated with an examined phecode. Only one of the variants was associated with a non-lipid disease phecode, ("myopia") but this association was not significant in the replication cohorts. In this large-scale PheWAS we did not find LDL-C-related variants in PCSK9, APOB, and LDLR to be associated with non-lipid-related phenotypes including diabetes, neurocognitive disorders, or cataracts.

Abstract
The avian adeno-associated virus (AAAV) has been proved to be an efficient gene transfer vector for human gene therapy and vaccine research. In this experiment, an AAAV-based vaccine was evaluated for the development of a vaccine against duck hepatitis a virus type 1 (DHAV-1). The major capsid VP1 gene was amplified and subcloned into pFBGFP containing the inverted terminal repeats of AAAV, and then the recombinant baculovirus rBac-VP1 was generated. The recombinant AAAV expressing the VP1 protein (rAAAV-VP1) was produced by co-infecting Sf9 cells with rBac-VP1 and the other 2 baculoviruses containing AAAV functional genes and structural genes respectively, and confirmed by electron microscopy, Western blotting and immunofluorescence assays. Quantitative real-time PCR revealed that the titer of rAAAV-VP1 was about 9 × 1012 VG/mL. Immunogenicity was studied in ducklings. One day ducklings were injected intramuscularly once with rAAAV-VP1. Serum from rAAAV-VP1-vaccinated ducklings showed a systemic immune response evidenced by VP1-specific enzyme-linked immunosorbent assay and virus neutralization test. Furthermore, all ducklings inoculated with rAAAV-VP1 were protected against DHAV-1 challenge. The data of quantitative real-time RT-PCR from livers of challenged ducklings also showed that the level of virus copies in rAAAV-VP1 group was significantly lower than that of the PBS group. Collectively, these results demonstrate that the AAAV-based vaccine is a potential vaccine candidate for the control of duck viral hepatitis.

Abstract
Current approaches to predicting a cardiovascular disease (CVD) event rely on conventional risk factors and cross-sectional data. In this study, we applied machine learning and deep learning models to 10-year CVD event prediction by using longitudinal electronic health record (EHR) and genetic data. Our study cohort included 109, 490 individuals. In the first experiment, we extracted aggregated and longitudinal features from EHR. We applied logistic regression, random forests, gradient boosting trees, convolutional neural networks (CNN) and recurrent neural networks with long short-term memory (LSTM) units. In the second experiment, we applied a late-fusion approach to incorporate genetic features. We compared the performance with approaches currently utilized in routine clinical practice – American College of Cardiology and the American Heart Association (ACC/AHA) Pooled Cohort Risk Equation. Our results indicated that incorporating longitudinal feature lead to better event prediction. Combining genetic features through a late-fusion approach can further improve CVD prediction, underscoring the importance of integrating relevant genetic data whenever available.

Abstract
Objective: To investigate the diagnostic value of neuron-specific enolase(NSE), central nervous system specific protein(S100β), interleukin-6(IL-6) in sepsis-associated encephalopathy(SAE). Methods: Clinical data of patients admitted to ICU and diagnosed with sepsis were collected from January 2015 to June 2016 in Xiangya Hospital, Central South University. SAE was defined as cerebral dysfunction in the presence of sepsis that also fulfilled the exclusion criteria. The acute physiology and chronic health score (APACHE Ⅱ), sequential organ failure assessment (SOFA), NSE, S100β, IL-6, ICU stay time and 28-day mortality were compared between the two groups. NSE, S100β and IL-6 were measured on the 1st and 3rd day in ICU to determine the optimal cut-off value of SAE. Results: Among 59 enrolled patients, 36 were assigned to SAE group while 23 were non-SAE group. The SAE group had a significantly higher APACHE Ⅱ and SOFA scores, as well as the length of ICU stay (P<0.01). The levels of NSE, S100β and IL-6 in the two groups both increased on the 1st day, and decreased on the 3rd day. The level of NSE on the 1st day[19.28(13.00, 30.52) μg/L vs 16.61(7.58, 22.01 μg/L)] and the 3rd day[16.03(9.40, 21.29) μg/L vs 11.39(8.49, 15.00) μg/L, P=0.029], IL-6 on the 1st day[676.25(81.34, 5 000.00) mg/L vs [209.10(42.27, 648.20) mg/L, P=0.005] and the 3rd day[157.10(72.85, 687.63) mg/L vs 55.92(31.62, 177.00) mg/L, P=0.026] of SAE group was significantly higher than those of non-SAE group. However S100β between groups on the 1st day [0.33(0.15, 0.54) μg/L vs 0.23(0.16, 0.53) μg/L] and the 3rd day[0.19(0.10, 0.29) μg/L vs 0.10(0.05, 0.17) μg/L] was neither significant (P>0.05). The diagnostic values for SAE of NSE, S100β and IL-6 were 14.36 μg/L, 0.14 μg/L and 91.305 mg/L with sensitivity 61.1%, 61.1%, 72.2% and specificity 73.9%, 69.6%, 69.6%, respectively. The diagnostic AUC of NSE and IL-6 combination was 0.774, 95%CI 0.651-0.896. Conclusion: All sepsis patients have different degrees of brain injury. NSE combined with IL-6 on the 3rd day in ICU demonstrates the diagnostic significance of SAE.

Abstract
IMPORTANCE Whether low levels of low-density lipoprotein cholesterol (LDL-C) are associated with increased risk of sepsis and poorer outcomes is unknown. OBJECTIVE To examine the association between LDL-C levels and risk of sepsis among patients admitted to the hospital with infection. DESIGN, SETTING, AND PARTICIPANTS Cohort study in which deidentified electronic health records were used to define a cohort of patients admitted to Vanderbilt University Medical Center, Nashville, Tennessee, with infection. Patients were white adults, had a code indicating infection from the International Classification of Diseases, Ninth Revision, Clinical Modification, and received an antibiotic within 1 day of hospital admission (N = 61 502). Data were collected from January 1, 1993, through December 31, 2017, and analyzed from January 24 through October 31, 2018. INTERVENTIONS Clinically measured LDL-C levels (excluding measurements <1 year before hospital admission and those associated with acute illness) and a genetic risk score (GRS). MAIN OUTCOMES AND MEASURES The primary outcome was sepsis; secondary outcomes included admission to an intensive care unit (ICU) and in-hospital death. RESULTS Among the 3961 patients with clinically measured LDL-C levels (57.8% women; mean [SD] age, 64.1 [15.9] years) and the 7804 with a GRS for LDL-C (54.0% men; mean [SD] age, 59.8 [15.2] years), lower measured LDL-C levels were significantly associated with increased risk of sepsis (odds ratio [OR], 0.86; 95% CI, 0.79-0.94; P = .001) and ICU admission (OR, 0.85; 95% CI, 0.76-0.96; P = .008), but not in-hospital mortality (OR, 0.80; 95% CI, 0.63-1.00; P = .06); however, none of these associations were statistically significant after adjustment for age, sex, and comorbidity variables (OR for risk of sepsis, 0.96 [95% CI, 0.88-1.06]; OR for ICU admission, 0.94 [95% CI, 0.83-1.06]; OR for in-hospital death, 0.97 [95% CI, 0.76-1.22]; P > .05 for all). The LDL-C GRS correlated with measured LDL-C levels (r = 0.24; P < 2.2 × 10-16) but was not significantly associated with any of the outcomes. CONCLUSIONS AND RELEVANCE Results of this study suggest that lower measured LDL-C levels were significantly associated with increased risk of sepsis and admission to ICU in patients admitted to the hospital with infection; however, this association was due to comorbidities because both clinical models adjusted for confounders, and the genetic model showed no increased risk. Levels of LDL-C do not appear to directly alter the risk of sepsis or poor outcomes in patients hospitalized with infection.

Abstract
Objective: To investigate the risk factors for multiparous pelvic floor muscles injury during 6-8 weeks after delivery. Method: From June 2015 to April 2017, 1917 women (1 523 primigravidas and 294 multiparas) were accepted postpartum pelvic floor function screening during 6-8 weeks after delivery in Beijing Hospital.Pelvic examination and pelvic floor muscle strength testing were carried out in these women.All the data were analyzed with multivariate logistic regression method to explore the related factors for postpartum pelvic floor muscle injury. Result: The incidence of muscle strength grades less than third grade was 63.60 % (type Ⅰ muscle fiber) and 24.83 % (type Ⅱ muscle fiber). Multivariate analysis showed that time interval, between two deliveries, less than 3 years (OR=2.16, 95%CI 1.21-3.86), and maternal BMI<18.5 (OR=3.04, 95%CI 1.10-9.30) and BMI≥28 (OR=3.04, 95%CI 1.10-9.30) before pregnancy were risk factors for postpartum injury of type Ⅰ muscle fiber. Gestational age more than 40 weeks increased the risk of damaging type Ⅱ muscle fiber (OR=2.79, 95%CI 1.156-6.76). Compared with cesarean section, vaginal delivery significantly increased the risk of injury of type Ⅰ and Ⅱ pelvic floor muscle fibers (P<0.05). Conclusion: The incidence of multiparous pelvic floor muscle injury was high in early postpartum period.Several factors are related to the pelvic floor muscle injury.Pelvic floor rehabilitation in early postpartum and maternal education may be helpful to reduce the radio of injury.

Abstract
Tizanidine, a widely used muscle relaxant that can lower blood pressure, is metabolized by the cytochrome P450 1A2 (CYP1A2). We studied 1,626 patients prescribed tizanidine and 5,012 prescribed cyclobenzaprine concurrently with a strong CYP1A2 inhibitor. The primary outcome was severe hypotension, defined as systolic blood pressure (SBP) ≤ 70 mmHg during periods of drug co-exposure. Severe hypotension occurred more often in the tizanidine group (2.03%; n = 33) than the cyclobenzaprine group (1.28%; n = 64); odds ratio (OR) = 1.60; P = 0.029. This difference remained statistically significant after adjustment for a log-transformed propensity score that included age, sex, race, Charlson's comorbidity index, and concurrent use of antihypertensive medications (OR = 1.57; P = 0.049). A sensitivity analysis that defined hypotension as SBP < 90 mmHg also yielded higher rates of hypotension among patients prescribed tizanidine. In conclusion, CYP1A2 inhibition increases the risk of hypotensive episodes associated with the use of tizanidine in routine clinical practice.

Abstract
Background: Smoking among Chinese women accounts for a small proportion, but the incidence and mortality rates of female lung cancer is increasing in recent years. Studies found that there were changes in histologic subtypes of lung cancer patients in China. Aim: This study investigated the tobacco smoking and trends in histologic subtypes of female lung cancer in a cancer hospital in China. Methods: Demographic, smoking history and histologic information about female lung cancer patients diagnosed or treated from 2000 to 2012 was collected from Cancer Hospital, Chinese Academy of Medical Science (CHCAMS). Trends of histologic subtypes calculated with annual percentage change (APC). The distribution differences of adenocarcinoma (ADC), squamous cell carcinoma (SCC), small cell lung cancer (SCLC) and the other subtypes between smokers and nonsmokers were calculated by 7th AJCC cancer staging. Results: Totally of 5,870 female cases of lung cancer, including 630 with history of smoking and 5,240 without, were analyzed. The number of female lung cancer patients increased from 509 (2000-2002) to 1744 (2012-2013). The main histologic type of lung cancer was adenocarcinoma (ADC) (72.93%), followed by small cell lung cancer (SCLC) (11.06%), squamous cell carcinoma (SCC) (8.38%) and the other (7.63%). Among smokers, the proportion of SCC decreased from 40.5% to 23.7% (APC = -11.68%, P = 0.005), however, the ADC increased from 35.7% to 50.7% (APC = 8.63%, P = 0.009). In nonsmokers, the ADC was 76.1%, and SCC was 5.9%. ADC increased from 63.1% to 80.6% (APC = -21.33%, P = 0.006), SCC decreased from 13.6% to 4.5% (APC = 3.86%, P = 0.016). Among squamous cell carcinoma, the cases with history of smoking were more likely diagnosed at early stages (I/II: 47.1%) than those at late stages (III, 34.3%; IV, 18.6%). Conclusion: The number of female lung cancer patients was increased in CHCAMS by year of diagnosis. In both smoking and nonsmoking cases, the proportion of adenocarcinoma was increasing. Among the squamous cell carcinoma, smokers seem to find in early stages.

Abstract
Objective: To investigate the efficacy and safety of lobaplatin (LBP) plus S-1 for advanced gastric cancer (AGC) and determine the potential role of circulating tumor cells (CTC) for predicting the therapeutic response and prognosis. Methods: From January 2014 to February 2015, 64 consecutive patients with AGC received lobaplatin plus S-1 chemotherapy in Liaocheng People's Hospital. The clinical features, clinical response, adverse effects, prognosis and CTC pre- and post-treatment were retrospectively analyzed. The correlation between CTC and patients' disease control rate (DCR), objective response rate (ORR), progression free survival (PFS) as well as overall survival (OS) were investigated. Results: All 64 patients completed 2 cycles of chemotherapy.The number of patients who achieved complete regression, partial regression, stable and progression were 0, 24 (37.5%), 18 (28.1%) and 22 (34.4%), respectively. ORR was 37.5% and DCR was 65.6%. The median PFS was 10.8 months(95%CI 7.1-12.0) and the median OS was 16.1 months(95%CI 12.4-18.8). The ORR and PFS were not significantly different between patients with baseline CTC≥2 and CTC<2 (25.0% vs 53.6%, P=0.150; 6.2 months vs 7.5 months, P=0.780), while the DCR and OS were significantly different (45.9% vs 90.0%, P=0.008; 10.5 months vs 17.2 months, P<0.001). After 2 cycles of chemotherapy, the ORR and DCR in patients with CTC≥2 were 16.7% and 45.9%, respectively, which were significantly lower than those observed in patients with CTC<2 (50.0% and 90.0%, respectively). The former also had shorter median PFS and OS (6.6 months vs 8.9 months, 8.4 months vs 15.0 months, respectively). Patients with persistently CTC<2 or those exhibiting an conversion to CTC<2 following chemotherapy had an improved PFS and OS, while patients with persistently CTC≥2 or those exhibiting an conversion to CTC≥2 following therapy had shorter PFS and OS.The most frequent adverse effects were grade 1 or 2 gastrointestinal discomfort and myelosuppression. No patients discontinued chemotherapy because of adverse events. Conclusions: Lobaplatin plus S-1 had manageable safety profile and promising antitumor activity in patients with AGC. CTC could be used as a biomarker in evaluating therapeutic response and predicting their prognosis.
