Abstract
Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

Abstract
The compressed ultrafast photography (CUP) can capture non-repetitive time-evolving events at 7 × 1013 fps, which is anticipated to find a diverse range of applications in physics, biomedical imaging, and materials science. The feasibility of diagnosing ultrafast phenomenon of Z-pinch by using the CUP has been analyzed in this article. Specifically, a dual-channel CUP design has been adopted for acquiring high quality reconstructed images and the strategies of identical masks, uncorrelated masks, and complementary masks have been compared. Furthermore, the image of the first channel was rotated by 90° to balance the spatial resolution between the sweep direction and the non-sweep direction. Both five synthetic videos and two simulated Z-pinch videos were chosen as the ground truth to validate this approach. The average peak signal to noise ratio of the reconstruction results is 50.55 dB for the self-emission visible light video and 32.53 dB for the laser shadowgraph video with unrelated masks (rotated channel 1). The simulation results show that the time-space-evolving process of plasma distribution can be well retold, and the phenomenon of plasma instability can be accurately diagnosed by the dual-channel CUP with unrelated masks (rotated channel 1). This study may promote the practical applications of the CUP in the field of accelerator physics.

Abstract
Objective: To investigate the relationship between V444A mutation of the ABCB11 gene and primary intrahepatic stone (PIS). Methods: A total of 164 patients (including 91 males and 73 females, with an average age of (46.0±13.0) years) with PIS and 164 healthy (including 99 males and 65 females, with an average age of (43.8±16.7) years) volunteers were enrolled in this case-control study between October 2017 and June 2019. TaqMan-MGB was used for detecting the V444A polymorphism site of the ABCB11 gene. All the genotypes and allele frequencies were calculated. Pearson chi-squared test was performed to detect the differences in allele and genotype distribution between the two groups. Logistic regression analysis was used to identify genotypes associated with PIS. Results: There was no significant difference in age and gender between the two groups(both P>0.05). The distributions of V444A allele and genotype accorded with Hardy-Weinberg equilibrium law (P=0.161), which indicated that the selected control group represented statistically acceptable sample. Two alleles of T and C, and three genotypes of TT, TC and CC were detected in the locus of V444A. The T and C allele frequencies in the PIS group and the control group were 28.4% vs 35.4%, and 71.6% vs 64.6%, respectively. The frequencies of the T and C alleles were not different between the two groups (P=0.054). The frequencies of TT, TC and CC genotypes in the two groups were 5.5%, 45.7%, 48.8%, and 14.6%, 41.5%, 43.9%, respectively, with significant difference between the two groups (P=0.023). Logistic regression analysis revealed the V444A polymorphism (TC heterozygous mutation) was associated with PIS. Conclusion: ABCB11 gene polymorphism at the site of V444A may be related to the susceptibility of PIS.

Abstract
The aim of this study was to investigate the effects of the inclusion levels of different types of rapeseed meal (RSM) on performance, organ weight, and serum biochemical parameters in Cherry Valley ducks in the starter period and grower-finisher period. In Exp. 1, a total of 750 seven-day-old male ducklings were divided into 5 dietary treatments with 6 replicate pens of 25 birds per pen. The starter diets with the inclusion of 0, 5, 10, 15, or 20% of double-low RSM contained 0, 1.37, 2.15, 3.46, or 5.31 µmol glucosinolates (GLS)/g in the finished feed (from day 7 to 21). In Exp. 2, a total of 900 fifteen-day-old male ducklings were divided into 6 dietary treatments with 6 replicate pens of 25 birds per pen. The grower-finisher diets with the inclusion of 0, 5, 10, 15, 20, or 25% of Indian RSM contained 0, 7.67, 15.34, 24.66, 31.21, or 38.44 µmol GLS/g in the finished feed (from day 15 to 42). For ducklings in the starter period (Exp. 1), body weight gain and feed intake decreased linearly as the dietary double-low RSM inclusion level increased at day 7 to 14, while growth rate was not influenced by dietary double-low RSM inclusion levels at day 15 to 21 and day 7 to 21. For ducks in the grower-finisher period (Exp. 2), growth performance decreased linearly as the dietary RSM inclusion level increased from 5 to 20%. In addition, dietary RSM inclusion levels induced liver enlargement in ducklings at day 21 (5 to 20% double-low RSM with 1.37 to 5.31 µmol/g GLS) and thyroid enlargement accompanied by increased serum AST and ALP activities in ducks at day 42 (5 to 15% Indian RSM with 7.67 to 23.66 µmol/g GLS). Therefore, our results indicated that the upper limit of using RSM sources in feed formulation should consider the anti-nutritional factor of GLS content at different stages of duck growth.

Abstract
B7-H4 is member of the B7 family that negatively regulates the immune response, which are important for fine-tuning of the tumor microenvironment. Dysregulation of B7-H4 expression has been associated with tumor progression. However, expression level of B7-H4 in hepatocellular carcinoma (HCC) tissues is still a controversial topic. In addition, whether serum B7-H4 expression of HCC patients has any clinical value is unknown. We compared serum levels of B7-H4 in patients with HCC and healthy controls by using the ELISA method. Association between serum B7-H4 expression level and clinical parameters of HCC was further investigated. Log-rank test and Kaplan-Meier method were employed to evaluate the overall survival rate of HCC patients. Univariate and multivariate analysis of prognostic factors were performed with the Cox regression model. Our results showed that HCC patients had significantly higher serum B7-H4 level as compared with healthy controls (P < 0.001). In addition, serum B7-H4 expression was correlated with HCC clinical parameters including serum AFP expression and TNM stage. HCC patients in the higher serum B7-H4 expression group had a poorer 5-year overall survival rate (P = 0.028). Moreover, serum B7-H4 expression was shown to be an independent prognostic factor for HCC (P = 0.034). The findings from this study suggest that serum B7-H4 is an independent prognostic indicator for HCC and may be a promising biomarker for early diagnosis as well as disease prognosis of HCC.

Abstract
By deviating the nanodisk from the center in the silver nanocrescent/nanodisk structure, we find that the dipole, quadrupole and octupole modes can all induce very high local electric field enhancement (LFE, more than 750) for the coupling of nanocrescent and crescent gap modes, which makes the resonant wavelengths of the non-concentric nanostructures change from the visible to near infrared regions. In addition, the LFE factor of the quadrupole mode is more than 1000, which is suitable for single molecular detection by local surface enhanced spectroscopy.
