Abstract
Milk proteins can be used as encapsulation walls to increase the bioavailability of active compounds because they can bind hydrophobic, hydrophilic, and charged compounds. The objective of this study was to investigate the effects of astaxanthin (ASTA) encapsulation and the functional properties of milk protein and ASTA nanocomposites by an ultrasound-assisted pH-shifting treatment of different milk proteins, including milk protein concentrate (MPC), micellar casein (MCC), and whey protein isolate (WPI). The ultrasound-assisted pH-shifting treatment of milk protein helped to improve the encapsulation rate of ASTA. Therein, MCC showed great improvement of encapsulating ASTA after co-treatment with the raised encapsulated rate of 5.11%, followed by WPI and MPC. Furthermore, the nanocomposites of ASTA with milk protein exhibit improved bioavailability, antioxidant capacity, and storage stability. By comparison, MCC-encapsulated ASTA has the best storage stability, followed by MPC, and WPI-encapsulated ASTA has the least stability over a 28-d storage period. The results of intrinsic fluorescence and surface hydrophobicity showed that milk protein underwent fluorescence quenching after binding to ASTA, which was due to the hydrophobic sites of the protein being occupied by ASTA. In general, the nanocomposites of milk protein and ASTA fabricated by using an ultrasound-assisted pH-shifting treatment have the potential to be better nano-delivery systems for ASTA in functional foods, especially MCC, which showed excellent performance in encapsulation after treatment technique.

Abstract
Objective: To investigate the association of cardiovascular diseases (CVD) with triglyceride glucose index (TyG) and TyG-related indicators in Uyghur populations of The Xinjiang Production and Construction Corps. Methods: Based on the cohort of the Uygur population of The Xinjiang Production and Construction Corps, 11 833 study subjects were included. The Kaplan-Meier method was used to estimate the cumulative incidence of CVD in each quartile of TyG and TyG-related indicators. Cox proportional hazards regression model was used to evaluate the relationship between TyG and CVD, TyG-related indicators and CVD. Framingham CVD risk score model (Framingham model) was used to evaluate whether the addition of TyG and TyG-related indicators could improve the predictive ability of the model. The potential mediating role of the TyG in the association between obesity and CVD was examined through mediation effect analysis. Results: The average age of the subjects was (37.00±13.67) years-old, and 51.0% were male. The median follow-up time was 5.67 years, with 1 288 CVD events. The cumulative incidence of CVD increased with the increase of TyG and TyG-related indicators quartiles, and compared with the Q1 group, the risk of CVD in the Q4 group of TyG, TyG-BMI, and TyG-WHtR increased by 20% (HR=1.20, 95%CI: 1.01-1.42), 77% (HR=1.77, 95%CI: 1.46-2.16) and 68% (HR=1.68, 95%CI: 1.36-2.09), respectively. After adding TyG, TyG-BMI, and TyG-WHtR to the Framingham model, respectively, the model's area under the curve, net reclassification improvement, and integrated discrimination improvement were improved. In the association between BMI, WHtR, and CVD, the proportion of mediating effects mediated by the TyG index was 10.55% and 11.50%. Conclusions: Elevated levels of TyG and TyG-related indicators were strongly associated with the risk of CVD in the Uyghur population of The Xinjiang Production and Construction Corps, with TyG-BMI being the most closely correlated with CVD. Early monitoring of TyG-BMI helps identify high-risk groups of CVD.

Abstract
BACKGROUND Pyogenic spondylitis is often manifested as atypical low back pain and fever, which makes it easy to be confused with other diseases. Here we report a case of pyogenic spondylitis and describe the diagnosis and treatment based on the related literature.
CASE SUMMARY The reported case suffered from pyogenic spondylitis caused by Escherichia coli and complicated with bacteremia and psoas abscess. Acute pyelonephritis was initially diagnosed due to atypical symptoms. Symptoms were improved from antibiotic treatment while developing progressive lower limb dysfunction. One month post the admission, the patient underwent anterior lumbar debridement + autogenous iliac bone graft fusion + posterior percutaneous screw-rod internal fixation, and received 6 wk of antibiotic treatment after the operation. Reexamination 4 mo post the operation showed that the patient had no evident pain in the waist, and walked well with no evident dysfunction of lower limbs.
CONCLUSION Here we describe the application value of several imaging examinations, such as X-ray, computed tomography and magnetic resonance imaging, and certain tests like erythrocyte sedimentation rate and C-reactive protein in the clinical treatment of pyogenic spondylitis. This disease requires early diagnosis and treatment. Sensitive antibiotics should be used in early stages and surgical intervention should be taken if necessary, which may help for a speedy recovery and prevent the occurrence of severe complications.

Abstract
Objective: To describe the distribution characteristics of tea consumption in adult twins recruited in the Chinese National Twin Registry (CNTR) and provide clues to genetic and environmental influences on tea consumption. Methods: Enrolled in CNTR during 2010-2018, 25 264 twin pairs aged 18 years and above were included in subsequent analysis. Random effect models were used to estimate tea consumption in the population and regional distribution characteristics. The concordance rate of the behavior and difference in consumption volume of tea within pairs were also described. Results: The mean age of all subjects was (35.38±12.45) years old. The weekly tea consumers accounted for 17.0%, with an average tea consumption of (3.36±2.44) cups per day. The proportion of weekly tea consumers was higher among males, 50-59 years old, southern, urban, educated, and the first-born in the twin pair (P<0.05), and lower among unmarried individuals (P<0.001). Within-pair analysis showed that the concordance rate of tea consumption of monozygotic (MZ) twins was higher than that of dizygotic (DZ) twins and the overall heritability of tea consumption was 13.45% (11.38%-15.51%). Stratified by the characteristics mentioned above, only in males, the concordance rate of MZ showed a tendency to be greater than that of DZ (all P<0.05). The differences in consumption volume of tea within twin pairs were minor in MZ among males (P<0.05), while the differences were not significant in female twins. Conclusion: There were discrepancies in the distribution of tea consumption among twins of different demographic and regional characteristics. Tea consumption was mainly influenced by environmental factors and slightly influenced by genetic factors. The size of genetic factors varied with gender, age, and region, and gender was a potential modified factor.

Abstract
Objective: To analyze whether triglyceride-glucose (TyG) index is associated with increased risk of cardiovascular diseases (CVD) and the value of TyG index in predicting CVD risk among Kazakh and Uighur population of Xinjiang. Methods: In this study, 5 375 Kazakh and Uygur people of Xinyuan county and Jiashi county were selected as the research objects. Subjects were divided into four groups based on the quartile of the TyG index level. Cox regression model was used to analyze the association between TyG index with the risk of CVD. The dose-response relationship between TyG index and CVD risk was described by restricted cubic splines. The area under the receiver operating characteristic curve, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to estimate the value of TyG index for predicting CVD. Mediating effect analysis was conducted to analyze the mediating effect of TyG index in the association between body mass index and CVD. Results: The age of subjects was 41.06(30.11,53.00)years old, with 46.30%(2 489/5 375)was male. After multivariate adjustment, there was an increasing trend between the risk of CVD and the higher TyG index Ptrend<0.001, compared with subjects of TyG index in Q1, the HR (95%CI) of Q2, Q3, and Q4 groups was 1.53, 1.23 and 1.73, respectively. Restricted cubic splines showed that TyG index was the linearly associated with the risk of CVD. TyG index could improve the prediction ability of Framingham model for the risk of CVD (NRI=0.106,P=0.010; IDI=0.003,P=0.030). The mediating effect analysis showed that in the relationship between body mass index and CVD, the TyG index had a mediating effect (P<0.001), and the ratio of mediating effect was 12.69%. Conclusion: TyG index is an independent predictor of CVD risk among kazakh and Uygur population in Xinjiang and has a good predictive value for the risk of CVD.

Abstract
Objective: To describe the distribution characteristics of coronary heart disease in adult twins recruited from Chinese Twin Registry (CNTR), and provide clues and evidence for the effect of genetic and environmental influences on coronary heart disease. Methods: By using the data of CNTR during 2010-2018, a total of 34 583 twin pairs aged ≥18 years who completed questionnaire survey and had related information were included in the current study to analyze the population and area distribution characteristics of coronary heart disease. Random effect models were used to compare the differences between groups. The concordane rate of coronary heart disease were calculated respectively in monozygotic (MZ) twin pairs and dizygotic (DZ) twin pairs to estimate the heritability. Results: The twin pairs included in this analysis were aged (34.2±12.4) years. The overall prevalence rate of coronary heart disease in twin pairs was 0.7%. Twin pairs who were women, older, obese and lived in northern China had higher prevalence of coronary heart disease (P<0.05). Intra-pair analysis in the same-sex twin pairs found that the concordane rate of coronary heart disease was higher in MZ twin pairs (25.3%) than in DZ twins (7.4%), and the difference was statistically significant (P<0.001). The overall heritability of coronary heart disease was 19.3% (95%CI: 11.8%-26.8%). Stratified by gender, age and area, the concordane rate was still higher in MZ twin pairs than in DZ pairs. Participants who were women, aged 18-30 years or ≥60 years and lived in northern China had a higher heritability of coronary heart disease. Conclusion: The distribution of coronary heart disease in twin pairs differed in populations and areas. The prevalence of coronary heart disease was affected by genetic factors, but the effect varied with age, gender and area.

Abstract
Objective: To describe the distribution characteristics of type 2 diabetes in twins in Chinese National Twin Registry (CNTR), provide clues and evidence for revealing the influence of genetic and environmental factors for type 2 diabetes. Methods: Of all twins registered in the CNTR during 2010-2018, a total 18 855 twin pairs aged ≥30 years with complete registration information were included in the analysis. The random effect model was used to describe the population and area distribution characteristics and concordance of type 2 diabetes in twin pairs. Results: The mean age of the subjects was (42.8±10.2) years, the study subjects included 10 339 monozygotic (MZ) twin pairs and 8 516 dizygotic (DZ) twin pairs. The self-reported prevalence rate of type 2 diabetes was 2.2% in total population and there was no sighificant difference between MZ and DZ. Intra-twin pairs analysis showed that the concordance rate of type 2 diabetes was 38.2% in MZ twin pairs, and 16.0% in DZ twin pairs, the difference was statistically significant (P<0.001). The concordance rate of type 2 diabetes in MZ twin parts was higher than that in DZ twin pairs in both men and women, in different age groups and in different areas (P<0.05). Further stratified analysis showed that in northern China, only MZ twin pairs less than 60 years old were found to have a higher concordance rate of type 2 diabetes compared with DZ twin pairs (P<0.05). In southern China, the co-prevalence rate in male MZ twin pairs aged ≥60 years was still higher than that in DZ twin pairs (P<0.05). Conclusion: The twin pairs in this study had a lower self-reported prevalence of type 2 diabetes than the general population. The study results suggested that genetic factors play a role in type 2 diabetes prevalence in both men and women, in different age groups and in different areas, however, the effect might vary.

Abstract
Ultrafast laser-induced phase/structural transitions show a great potential in optical memory and optical computing technologies, which are believed to have advantages of ultrafast speed, low power consumption, less heat diffusion and remote control as compared with electronic devices. Here, we review and discuss the principles of orbital-selective electronic excitation and its roles in phase/structural transitions of phase-change memory (PCM) materials, including Sc0.2Sb1.8Te3 and GeTe phases. It is demonstrated, that the mechanism can influence the dynamics or results of structural transitions, such as an ultrafast amorphization of Sc0.2Sb1.8Te3 and a non-volatile order-to-order structural transition of GeTe. Without thermal melting, these structural transitions have the advantages of ultrafast speed and low power consumption. It suggests that the orbital-selective electronic excitation can play a significant role in discovering new physics of phase change and shows a potential for new applications.

Abstract
Objective: To investigate the prognosis-related factors and its predictive value in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). Methods: Sixty-three cases with HBV-ACLF were enrolled. According to the prognosis of 4-weeks, patients were divided into survival and death group. Univariate and multivariate analyses were performed on the clinical data of the two groups of patients to screen the risk factors affecting prognosis, evaluate its predictive value, and compare them with the MELD score, CTP score, and CLIFACLF score. The data were analyzed using t-test, Mann-Whitney U test, χ (2) test. Multiple logistic regression analysis was used for multiple risk factors. Results: There were 63 cases with HBV-ACLF, with 16 cases (25.40%) in the 4-week survival group, and 47 cases (74.60%) in the death group. The survival group age was 38.38 ± 14.50 years, which was significantly lower than the age of the death group 52.28 ± 12.51 years (P < 0.001). The survival group alpha-fetoprotein (AFP) level was 91.21 (8.38 ~ 154.10)μg/L, which was significantly higher than the level of the death group [12.60 (5.70 ~ 33.80) μg/L, P = 0.039]. The survival group alanine aminotransferase (ALT) level was 925.65 (523.43 ~ 1 364.80) U/L, which was much higher than that of the death group [371.60 (117.30 ~ 895.30) U/L, P = 0.040]. The survival group serum sodium level was (136.59 ± 4.03) mmol /L, which was significantly higher than the level of the death group [(132.22 ± 6.37) mmol/L, P = 0.013]. The survival group ascites severity level was much lower than that of the death group (P = 0.008). The survival group creatinine level was 56.50(49.43 ~ 86.25) μmol/L, which was much lower than the level of the death group [86.20 (68.00 ~ 143.00) μmol/L, P = 0.003]. Multivariate logistic regression analysis showed that ascites (OR = 0.470, 95% CI: 0.226 ~ 0.977) and age (OR = 0.941, 95% CI: 0.888 ~ 0.996) were risk factors affecting the HBV-ACLF prognosis. The area under the curve predicted liver failure prognostic score for ascites and age was 0.821, and the sensitivity and specificity were 68.8% and 87.2%, which was higher than the area under the curve predicted by the MELD score, CTP score, and CLIFACLF score, respectively. Conclusion: Age and ascites can be used to predict the clinical outcome in patients with HBV-ACLF. Younger patients without ascites have a higher survival rate at 4-weeks, but older patients with ascites are more likely to have a lower survival rate.

Abstract
Abstract
Purpose
To investigate the value of Global Registry of Acute Coronary Events (GRACE) score combined with B-type natriuretic peptide (BNP) and glycosylated hemoglobin (HbA1c) in predicting in-hospital major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).
Methods
A total of consecutive 675 patients with acute coronary syndrome (ACS) admitted to our hospital from June 2019 to June 2020, and finally, 319 patients treated with the percutaneous coronary intervenion (PCI) were enrolled. Major adverse cardiovascular events (MACE) during hospitalization included cardiac death, cardiogenic shock, congestive heart failure, recurrent ischemic chest pain and malignant arrhythmia. The area under the curve (AUC) was used to evaluate the predictive value of MACE during hospitalization.
Results
Among 319 patients, during hospitalization, 26 patients (8.15%) experienced the MACE. Compared to that of non-MACE group, there were more patients with previous history of heart failure (P<0.001), lower in-admission systolic and diastolic blood pressure (P all<0.05), and higher heart rate, GRACE score, BNP, and HbA1c levels in the MACE group (P all<0.05). Multivariate logistic regression analysis showed that history of heart failure (OR: 1.498, 95% CI: 1.144–2.249), GRACE score (OR: 1.040, 95% CI: 1.017–1.063), BNP (OR: 1.019, 95% CI: 1.012–1.026) and HbA1C (OR: 1.199, 95% CI: 1.043–1.378) were independent risk factors for MACE in patients with ACS after PCI (P all<0.05). The AUC of GRACE score for predicting MACE in ACS patients after PCI was 0.758, while the AUC of BNP and HbA1C was 0.838 and 0.788, respectively. When GRACE score combined with BNP and HbA1c, the AUC was increased to 0.876, which was significantly higher than the GRACE score alone (Z=4.142, P<0.001).
Conclusion
In this study, we reported for the first time, GRACE score combined with BNP and HbA1c significantly improved the predictive value of in-hospital MACE in ACS patients after PCI compared with traditional GRACE score, which can help clinicians identify high risk patients to improve their prognosis in the clinical practice.

Abstract
Pudong White (PDW) pigs, historically originating from Shanghai, are the only Chinese indigenous pigs characterised by their completely white coats, with the exception of Rongchang pigs. However, there is limited information concerning their overall genetic structure or relationship with other breeds, especially the East Chinese (ECN) and European pigs. To uncover the genetic structure, selection signatures, and potential exotic introgression in PDW pigs, we sampled 15 PDW pigs using whole-genome sequencing (~20×). We then conducted in-depth population genetic analyses in 320 pigs from 27 global pig groups, namely, European wild boars, Chinese wild boars, and outgroup. Neighbour-joining tree and principal component analysis confirmed that PDW pigs belonged to the ecotype of ECN pigs. Both f3, D-statistics, and structure analysis showed that PDW pigs shared apparent alleles with Large White (LW) pigs. Three statistics, rIBD, a haplotype heat map and copy number variation, further indicated that PDW pigs shared apparent alleles with LW pigs at the KIT Proto-Oncogene, Receptor Tyrosine Kinase (KIT) and PARG-MARCHF8 loci, suggesting that the lineage of European pigs in PDW originated from LW pigs. After further detecting the KIT mutations in different pig breeds, PDW was confirmed to have the same duplication region 1, duplication region 2, and the splicing mutation on intron 17 of KIT as LW pigs that determine the white coat colour phenotype in European white pigs. We hypothesised that LW pigs were imported to China ∼110-160 years ago according to the admixture time estimate and then crossed with ECN pigs, resulting in the introgression of the KIT alleles that produce the white coat colour phenotype in the PDW pig breed. To our knowledge, this study presents the first thorough description of the genetic structure of PDW pigs via whole-genome resequencing data; moreover, the results provide a basis for the national project for the conservation of this unique Chinese local population.

Abstract
Objective: To investigate the effect of multi-material artifact reduction (MMAR) technique on the maxillofacial CT images of patients with metallic dental implants. Methods: The data of 30 patients with metal denture implants who underwent maxillofacial wide-detector CT scans in the Department of Radiology of the First Affiliated Hospital of Zhengzhou University from March 2019 to February 2020 were retrospectively collected. The images of the lesion sites of patients were all affected by the metal implants artifacts. The 120 kV-like, virtual monoenergetic images (VMI) (70, 90, 110 keV), VMI (70, 90, 110 keV)+MMAR images were reconstructed at venous phase by energy spectrum scanning. A total of 7 image sequences were obtained for each patient. The CT value and noise value of the lesion and the longus capitis muscle on the same plane were measured, and the artifact index (AI) of lesion was calculated.Friedman test and Wilcoxon test were used to evaluate image quality objectively and subjectively. Results: There were significant differences in SD and AI among the 7 groups (χ2=133.800,P<0.001;χ2=92.147,P<0.001). The SD[10 (8, 12)] and AI [6 (5, 9)]of VMI 110 keV+M images were the lowest, but there were no significant differences in AI between VMI 110 keV+M and VMI 90 keV+M image (P= 0.271). The SD and AI of VMI+M group were lower than those in VMI group (all P<0.05). There was significant difference in image score among the 7 groups (χ 2 = 151.199, P<0.001). The image scores of VMI (70, 90, 110 keV)+M group were higher than those of VMI group (Z=-4.583, P = 0.000; Z=-3.742, P = 0.000; Z =-2.449, P = 0.014). The subjective score of VMI 90 keV+M [4 (3, 4)] was the highest, higher than those of other 6 groups (all P<0.05), in 26 out of 30 cases, lesions displayed clear contrast, and the artifacts eliminated completely. Conclusion: The MMAR technique of wide-detector CT might effectively remove the metallic dental implants artifacts and improve the image quality. VMI 90 keV+MMAR images could achieve the best artifact removal effect and good tissue contrast.

Abstract
Peptidyl arginine deiminase 4 (PADI4), an enzyme that converts arginine residues to citrulline residues in the presence of calcium ions, affects the biochemical activities of proteins. The biological function of PADI4 as well as its mechanism in nasopharyngeal carcinoma (NPC) necessitates further investigation. PADI4 expression in NPC tissues and cells was detected using Western blot. qRT-PCR was used to determine the expression of miR-335-5p and PADI4 mRNA in NPC tissues and cells. BrdU assay and CCK-8 assay were employed to detect cell proliferation. Cell migration and invasion were evaluated using Transwell assay. NPC cells were exposed to different doses of radiation in vitro, and then colony formation assays were used to detect colony survival. The target relationship between miR-335-5p and PADI4 was verified using Western blot, qRT-PCR, and dual-luciferase reporter gene assays. Compared with normal mucosal epithelial tissues and cell lines, the expression level of PADI4 in NPC tissues and cells was significantly up-regulated. PADI4 overexpression promoted the proliferation, migration, and invasion of NPC cells. Under radiation, NPC cell survival was significantly promoted by the up-regulation of PADI4. Conversely, knock-down of PADI4 suppressed the above-mentioned malignant phenotypes. MiR-335-5p could bind with the 3' UTR of PADI4 mRNA, and suppressed the expression of PADI4. PADI4 down-regulated the expression of p21 and activated the mTOR signaling pathway. PADI4, which is negatively regulated by miR-335-5p, promotes the proliferation, migration, invasion and radioresistance of NPC cells by regulating the p21 and mTOR signaling pathways.

Abstract
The liver has a very special dual blood supply, including the portal vein (65%~75%) and hepatic artery (25%~35%). The hepatic veins returns blood to the systemic circulation via the portal vein, and hepatic artery after hepatic sinusoidal confluence. The lesions on the hepatic vein and its branches can cause ischemia and hypoxia or obstruction of the drainage system, portal hypertension, upper gastrointestinal variceal bleeding, hepatic encephalopathy, and so on. Clinically, hepatic vascular diseases are relatively rare, so the diagnosis and treatment are relatively difficult. Herein, we review the diseases related to the hepatic vascular system.

Abstract
Pioglitazone (PIO) attenuates cisplatin nephrotoxicity whereas the underlying mechanism remains unknown. Apoptosis is associated with mitochondrial dysfunction and SIRT1 activation can decrease cell apoptosis in cisplatin nephrotoxicity. Therefore, we explored whether the protective effect of PIO in cisplatin nephrotoxicity is achieved by suppressing mitochondria‐mediated apoptosis through SIRT1/p53 signalling regulation. Cell viability, apoptosis, survival rate, renal pathology and function were examined. Moreover, we also analysed the expression of SIRT1, Acetyl‐p53, mitochondrial membrane potential (MMP), reactive oxygen species (ROS), mitochondrial permeability transition pore (mPTP) opening, adenosine triphosphate (ATP) and apoptosis‐related protein in vivo and in vitro. Pioglitazone treatment significantly increased cell viability, promoted SIRT1‐p53 interaction, upregulated Bcl‐2 expression, activated SIRT1 and elevated mitochondrial ATP synthesis after cisplatin treatment. However, PIO decreased the generation of ROS, opening of mPTP, dissipation of MMP and translocation of cytochrome c after cisplatin treatment. Pioglitazone also reduced the activation of caspase‐3 and caspase‐9, lowered the ratio of Bax/Bcl‐2, attenuated kidney pathological damage and dysfunction, down‐regulated the expression of Acetyl‐p53, PUMA‐α and Bax and abated cell apoptosis after cisplatin treatment. The SIRT1 inhibitor, EX527, clearly reversed the protective effects of PIO. These results implied PIO attenuated cisplatin nephrotoxicity by suppressing mitochondria‐mediated apoptosis through regulating SIRT1/p53 signalling.

Abstract
Objective: To explore the clinical features and prognosis of gastric mucosa-associated lymphoid tissue lymphoma. Methods: The data of patients with gastric mucosa-associated lymphoid tissue lymphoma diagnosed and treated at Peking University Cancer Hospital from 2000 to 2019 were collected, and their clinical characteristics, treatment options and effects, and prognosis were retrospectively analyzed. Results: The median age of 68 patients was 56 years old, and the ratio of men to women was 0.6∶1.0. Early patients accounted for about 76% (52/68). The most commonly used treatment is Helicobacter pylori eradication, followed by radiotherapy and chemotherapy. The total effective rate is 94%, of which the complete remission rate is 72%. With a median follow-up of 44 months, the 5-year progression-free survival (PFS) rate was 73%, and the overall survival (OS) rate was 83%. Prognostic factor analysis showed that albumin level (P=0.011) and international prognostic index (IPI)(P=0.017) are independent prognostic indicators of PFS, The 5-year PFS rate of patients with normal and reduced albumin was 77% and 50%, respectively, and the 5-year PFS rate of patients with IPI score<2 points and IPI ≥ 2 points was 80% and 48%, respectively. Lactate dehydrogenase (LDH) (P=0.016) and albumin level (P=0.025) are independent prognostic indicators of OS, and the 5-year OS rates of patients with normal and elevated LDH were 87% and 67%, respectively. The 5-year OS rates of patients with normal albumin and reduced were 92% and 73%, respectively. Conclusions: Gastric mucosa-associated lymphoid tissue lymphoma is sensitive to treatment and has a good prognosis. The patient's albumin and lactate dehydrogenase levels are independent prognostic indicators.

Abstract
Lysin motif (LysM)-containing proteins function as pattern-recognition receptors in plants to recognize different N-acetylglucosamine-containing ligands, thereby triggering specific defense responses against pathogens. However, the biological functions of these proteins in animals remain unclear. In this study, we characterized a novel LysM protein, designated as SpLysMD3, in mud crab Scylla paramamosain. The cDNA sequence of SpLysMD3 had 1058 bp with an open reading frame of 840 bp encoding a protein with 279 amino acid residues. The deduced protein contained a LysM domain and a transmembrane region. SpLysMD3 was highly expressed in gills, intestine, muscle, and hemocytes and upregulated after challenges with bacteria, suggesting that it may be involved in antibacterial defense. Binding assay showed that SpLysMD3 possessed specific binding activities to all tested microorganisms as well as bacterial cell wall components lipopolysaccharide (LPS) and peptidoglycan (PGN), indicating that SpLysMD3 was an important LPS- and PGN-binding protein in mud crab. Bacterial clearance assay revealed that coating bacteria with SpLysMD3 accelerated bacterial clearance in vivo. The promotion of bacterial clearance by SpLysMD3 was further determined by using SpLysMD3-silenced crabs injected with S. aureus or V. parahemolyticus. Silencing SpLysMD3 dramatically suppressed the bacterial clearance. Meanwhile, knockdown of SpLysMD3 also severely impaired the expression of a specific set of antimicrobial peptides (AMPs); moreover, SpLysMD3 overexpression can enhance the promoter activity of SpALF2. These results suggested that SpLysMD3 affected bacterial clearance by regulating AMPs. Collectively, all the results demonstrated that SpLysMD3 may function as a potential receptor involved in innate immunity by binding to LPS and PGN and by regulating AMPs to eliminate invading pathogen. This study provided new insights into the biological functions of LysM proteins in animals and the mechanisms underlying the antibacterial activity of crustaceans.

Abstract
Abstract Objective To discuss the related factors influencing the initiation time of forensic psychiatric assessment by analysis of the initiation time of forensic psychiatric assessment of criminal cases in Hunan Province. Methods Related data in assessment files of criminal cases accepted by 8 forensic psychiatric assessment institutions in Hunan Province from January 1, 2011 to December 31, 2016 were extracted. The Logistic regression analysis was used to explore the factors influencing the initiation time of forensic psychiatric assessment. After using property score matching (PSM) to control the influence of confounding factors, the efficiency of public security organs to initiate assessments of suspects with (without) mental disorders and with (without) responsibilities were compared. Results A total of 4 346 cases were included. The Logistic regression analysis suggested that the factors independently related to the initiation time of assessment include: cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime (all P<0.05). The initiation time of assessment of suspects diagnosed with mental disorder was shorter than those with none (P<0.05); the initiation time of assessment of suspects without criminal responsibility was shorter than those with responsibility (P<0.05). After using PSM to control confounding factors, the differences above still existed. Conclusion The cause of assessment, nationality of the assessed, history of diagnosis and treatment of mental illnesses, history of crimes, history of drug abuse, and status of alcohol consumption before the crime are factors that influence the efficiency of public security organs to initiate forensic psychiatric assessments. Under the current assessment initiation mode, forensic psychiatric assessment of suspects who have mental disorders, especially those with no responsibility may be given priority to initiate.

Abstract
Objective: To investigate the effect of long-chain non-coding RNA Fez family zinc finger protein 1 antisense RNA1 (lncRNA FEZF1-AS1) on the biological function of hepatocellular carcinoma (HCC). Methods: SMMC771 and BEL-7402 cells were transfected with sh-FEZF1-AS1 and OE-FEZF1-AS1, respectively. The expression of lncRNA FEZF1-AS1 was detected by real-time quantitative PCR. Cell proliferation was detected by Cell Counting Kit-8 (CCK-8), and apoptosis was detected by flow cytometry. The effects of lncRNA FEZF1-AS1 on invasion and migration were detected by Transwell and wound healing assays. The expression levels of adhesion molecules were detected by Western blot. The effect of lncRNA FEZF1-AS1 on the in vivo growth was verified by nude mice xenograft experiments. Results: The silencing or ectopic expression of lncRNA FEZF1-AS1 inhibited or promoted the proliferation of hepatocellular carcinoma cells. CCK-8 assay showed that the proliferation abilities of SMMC7721 and BEL-7402 cells in sh-FEZF1-AS1 transfection group significantly decreased, achieving (35.43±4.06)% and (34.68±3.97)%, respectively, on the fifth day. There were significant differences between sh-FEZF1-AS1 group and sh-NC group [52.21±8.46)% and (53.76±7.64)%] (all P<0.05). In contrast, the proliferation ability of SMMC7721 and BEL-7402 cells transfected with OE-FEZF1-AS1 was significantly increased, achieving (83.49±6.92)% and (80.31±3.13)%, respectively, on the fifth day. There were significant differences between OE-FEZF1-AS1 and OE-NC group [53.03±8.84)% and (55.11±7.09)%] (all P<0.05). The subsequent flow cytometry results showed that cell apoptotic rates of SMMC7721 and BEL-7402 cells transfected with sh-FEZF1-AS1 were (13.02±1.38)% and (11.88±1.29)%, respectively, which were significantly higher than those in sh-NC groups [(5.57±1.46)% and (8.06±1.42)%, respectively, all P<0.05]. In contrast, the apoptotic rates of SMMC7721 and BEL-7402 cells transfected with OE-FEZF1-AS1 were (3.01±0.39)% and (3.22±0.43)%, which were significantly lower than those in OE-NC groups [(6.68±0.96)% and (6.63±0.45)%, all P<0.05]. In addition, knockdown or overexpression of lncRNA FEZF1-AS1 expression inhibited or enhanced the migration and invasion abilities as well as the levels of adhesion molecules in hepatocellular carcinoma cells. After 30 days of feeding under the same conditions, the tumor volumes of sh-FEZF1-AS1 and sh-NC SMMC7721 cells xenograft mice models were (0.26±0.03) cm(3) and (0.63±0.06) cm(3), respectively, showing significant difference (P<0.05). The tumor volumes of sh-FEZF1-AS1 and sh-NC BEL-7402 cells were (0.31±0.02) cm(3) and (0.72±0.08) cm(3), and the difference was statistically significant (P<0.05). Conclusion: lncRNA FEZF1-AS1 may strengthen the growth, migration and invasion of hepatocellular carcinoma cells.

Abstract
Objective: To investigate the application of adaptive statistical iterative reconstruction-V (ASIR-V) in contrast-enhanced abdominal CT scanning with low-dose for liver cirrhosis. Methods: From June 2017 to May 2018, a total of 112 liver cirrhosis patients who underwent contrast-enhanced abdominal CT scanning were collected prospectively as the study group. According to Child-Pugh grading of liver function, the study group was divided into A, B and C groups. Thirty examiners with normal liver function who underwent contrast-enhanced abdominal CT scanning no abdominal diseases were collected as the control group. The control group applied 0 pre-ASIR-V. The study group applied 30%, 40% and 50% pre-ASIR-V in plain scanning, arterial and portal vein phase, respectively. The control and study group both combined with 60% post-ASIR-V. The difference of qualitative parameters (contrast to noise ratio of the liver, pancreas, spleen, abdominal aorta and portal vein), image noise and radiation dose were compared by One-way ANOVA. Subjective score of images were compared by Kruskal-Wallis H test. Results: The volume computed tomography dose index (CTDI(vol)), dose length product (DLP) and the effective dose (ED) of study group were lower than the control group in the same phase (F=13.354-28.192, P<0.01). And the ED were decreased by 1.12 (23.9%), 1.54 (33.5%), 2.14 mSv (46.7%). The CNR values of liver and portal vein in Child C group was 0.34-0.42 and 0.43-0.49 lower than that of Child A and control group, respectively (q=2.851-4.658, P<0.05). Image noise had no difference in study and control group. There were no statistical differences between each group of subjective score in arterial and portal vein phase. The mean score of Child C in portal phase was lower than 3, which affected the diagnosis. And there were significant difference among the control, Child A and Child C group(Z=26.734-29.218, P<0.05). Conclusions: According to the classification of liver function, liver cirrhosis combined with ASIR-V can ensure the image quality while reduce the radiation dose. When liver function is Child-Pugh A or B, preset 50%ASIR-V is recommended; 40%ASIR-V is recommended for Child-Pugh C.

Abstract
Objective: To investigate the relationship between Lipoprotein (LP) (a) level and the characteristics of tissue components of left main coronary artery (LMCA) plaque. Methods: A total of 102 patients with stable angina pectoris who underwent percutaneous coronary intervention (PCI) in the People's Hospital of Henan Province from June 2010 to October 2016 were included. We performed intravascular ultrasound-virtual histology (IVUS-VH) to their LMCAs and evaluated the tissue characteristics, and the blood level of total cholesterol (TC), triacylglycerol (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), ApoB, ApoA1, LP(a) were measured. According to the value of their LP(a) level they were divided into 2 groups (high LP(a) group (>300 mg/L) (n=35) and low LP(a) group (≤300 mg/L) (n=67)), then the relationship between the above lipid values and the tissue characteristics of the LMCA plaque in the patients were evaluated. Results: Patients with a high LP(a) had a larger percentage of fibrolipid volume and a smaller percentage fibrous volume compared to patients with a normal LP(a) (25%±5% vs 13%±6%, P<0.01 and 50%±8% vs 61%±9%, P<0.01). Using multivariate linear regression analysis after adjustment for the above-mentioned confounding factors, LP(a) had a significantly positive correlation with fibrolipid volume percentage (r=0.645, β=0.29, P<0.01), and had a negative correlation with fibrous volume percentage (r=-0.467, β=-0.32,P<0.01), suggesting that the LP(a) was associated with the vulnerability of the LMCA plaque. Conclusion: For the patients with stable angina pectoris, the LP(a) has a significantly positive correlation with the percentage of fibrolipid volume and a negative correlation with the percentage of fibrous volume, suggesting that the LP(a) could predict the vulnerability of the LMCA plaque.

Abstract
Egg drop syndrome virus (EDSV), a member of the family Adenoviridae and an economically important pathogen with a broad host range, leads to markedly decreased egg production. However, the molecular mechanism underlying the host-EDSV interaction remains unclear. Here, we performed high-throughput RNA sequencing (RNA-Seq) to study the dynamic changes in host gene expression at 6, 12, and 24 hours post-infection in duck embryo fibroblasts (DEFs) infected with EDSV. Atotal of 441 differentially expressed genes (DEGs) were identified after EDSV infection. Gene Ontology category and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that these DEGs were associated with multiple biological functions, including signal transduction, host immunity, virus infection, cell apoptosis, cell proliferation, and pathogenicity-related and metabolic process signaling pathways. We screened and identified 12 DEGs for further examination by using qRT-PCR. The qRT-PCR and RNA-Seq results were highly consistent. This study analyzed viral infection and host immunity induced by EDSV infection from a novel perspective, and the results provide valuable information regarding the mechanisms underlying host-EDSV interactions, which will prove useful for the future development of antiviral drugs or vaccines for poultry, thus benefiting the entire poultry industry.

Abstract
Organic single-crystalline semiconductors with long-range periodic order have attracted much attention for potential applications in electronic and optoelectronic devices due to their high carrier mobility, highly thermal stability, and low impurity content. Molecular doping has been proposed as a valuable strategy for improving the performance of organic semiconductors and semiconductor-based devices. However, a fundamental understanding of the inherent doping mechanism is still a key challenge impeding its practical application. In this study, solid evidence for the "perfect" substitutional doping mechanism of the stacking mode between the guest and host molecules in organic single-crystalline semiconductors using polarized photoluminescence spectrum measurements and first-principles calculations is provided. The molecular host-guest doping is further exploited for efficient color-tunable and even white organic single-crystal-based light-emitting devices by controlling the doping concentration. The clarification of the molecular doping mechanism in organic single-crystalline semiconductor host-guest system paves the way for their practical application in high-performance electronic and optoelectronic devices.

Abstract
Objective: To evaluate the clinical characteristics and survival outcomes of patients with de novo grade 3 or transformed follicular lymphoma (FL). Methods: Fifty-two patients treated at Peking University Cancer Hospital between January 2009 and September 2017 were assessed, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. Baseline characteristics, survival and prognostic factors were analyzed. Results: ① Twenty-six male and 26 female patients were enrolled, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. ②The 3-year progression-free survival (PFS) and overall survival (OS) for the entire cohort were 56.0% and 80.6%, respectively. Patients with international prognostic index (IPI) score 0-1 demonstrated significantly better 3-year PFS (80.3% vs 20.1%; t=18.902, P<0.001) and OS (95.7% vs 57.0%; t=10.406, P<0.001) than patients with IPI score 2-3. Three-year PFS (94.1% vs 37.2% vs 25.2%; P=0.002) and OS (100.0% vs 76.0% vs 59.8%; P=0.020) were also significantly different among patients with FLIPI 1 score 0-1, 2, ≥3. FLIPI 2 score was also identified as a prognostic factor for 3-year PFS (68.4%, 0, 0; P=0.001) and OS(87.5%, 76.2%, 0; P=0.003). ③Multivariate analysis indicated a significant association of PFS (HR=3.536, P=0.015) and OS (HR=15.713, P=0.015) with IPI. FLIPI 2 was associated with OS (score 0-1, HR=0.078, P=0.007; score 2, HR=0.080, P=0.022). Conclusion: De novo grade 3 or transformed FL might be a group of curable disease with current treatment strategies. IPI is still a prognostic tool in this scenario.

Abstract
Two-dimensional (2D) B-C-N alloys have recently attracted much attention but unfortunately, Chemical Vapor Deposition (CVD) B-C-N alloys typically phase separate. In spite of that, our analysis of the B-C-N alloy fabricated by electron-beam irradiation suggests that non-phase-separated B-C-N may in fact exist with a carbon concentration up to 14 at%. While this analysis points to a new way to overcome the phase-separation in 2D B-C-N, by first-principles calculations, we show that these B-C-N alloys are made of motifs with even numbers of carbon atoms, in particular, dimers or six-fold rings (in a molecule-like form), embedded in a 2D BN network. Moreover, by tuning the carbon concentration, the band gap of the B-C-N alloys can be reduced by 35% from that of BN. Due to a strong overlap of the wavefunctions at the conduction band and valance band edges, the non-phase-separated B-C-N alloys maintain the strong optical absorption of BN.

Abstract
The study of samples subjected to high pressure gas is an important asset in materials research and has consequently been a priority of the sample environment development at the Oak Ridge National Laboratory's (ORNL) neutron program. Such effort has resulted in the availability of an extensive combination of pressure cells and gas intensifiers (both commercially available and custom made). These resources are available across both neutron facilities at ORNL: the Spallation Neutron Source and the High Flux Isotope Reactor. Current capabilities include, for example, in situ measurements up to 6 kbar and a 3 kbar hydrogen-capable intensifier with a gas recovery feature. In this communication, we will review the existing suite of high pressure gas capabilities, with special emphasis on recent in-house developments. A number of examples will be presented to illustrate how such capabilities are being deployed on neutron beamlines to enable frontier science.

Abstract
Time-resolved diffraction has become a vital tool for probing dynamic responses to an applied stimulus. Such experiments traditionally use hardware solutions to histogram measured data into their respective bin. We will show that a major advantage of event-based data acquisition, which time-stamps measured diffraction data with 100 ns accuracy, is much preferred over hardware histogramming of the data by enabling postprocessing for advanced custom binning using a software solution. This approach is made even more powerful by coupling measured diffraction data with metadata about the applied stimuli and material response. In this work, we present a time-filter approach that leverages the power of event-based diffraction collection to reduce stroboscopic data measured over many hours into equally weighted segments that represent subsets of the response to a single cycle of the applied stimulus. We demonstrate this approach by observing ferroelectric/ferroelastic domain wall motion during electric field cycling of BaTiO3. The developed approach can readily be expanded to investigate other dynamic phenomena using complex sample environments.

Abstract
The nascent suite of single-crystal neutron diffractometers at the Oak Ridge National Laboratory has no equal at any other neutron scattering facility worldwide and offers the potential to re-assert single-crystal diffraction using neutrons as a significant tool to study nuclear and magnetic structures of small unit cell crystals, nuclear structures of macromolecules, and diffuse scattering. Signature applications and features of single-crystal neutron diffraction are high resolution nuclear structure analysis, magnetic structure and spin density determinations, contrast variation (particularly D2O/H2O) for nuclear structural studies, lack of radiation damage when using crystals of biological molecules such as proteins, and the fidelity to measure nuclear and magnetic diffuse scattering with elastic discrimination.

Abstract
Suppurative tonsillitis (ST) is a common respiratory disease in children. This study aims to investigate the association between calcium (Ca)/magnesium (Mg)/phosphorus (P) and the risk of onset of suppuration in tonsillitis in children. Seventy children with ST and 61 age- and sex-matched children with non-ST were enrolled in this study. The association between Ca/Mg/P and suppuration risk in tonsillitis was investigated. The relationship between Ca/Mg/P and the potential risk factors for ST were also studied. White blood cell (WBC), platelet (PLT), c-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels were significantly higher in the ST group than those in the non-ST group (p less than 0.05). Mg and P levels were significantly lower in the ST group than those in the non-ST group (p less than 0.05). There was no obvious difference in Ca level between the ST group and the non-ST group (p=0.762). A significantly negative association between P and PCT was noted (r=-0.236, p=0.035). The results indicated that Mg/P disorder may be associated with the susceptibility to suppuration in children with tonsillitis, inflammatory indexes may reflect this risk.

Abstract
Due to the large photoluminescence quantum yield, high mobility and good stability, organic super acid treated two-dimensional WSe2 has drawn much attention. However, reports about the influence of organic super acid treatment on the dynamic processes of excitons of monolayer WSe2 are still rare. In this work, through the broadband transient absorption spectra obtained using a femtosecond pump-probe system, we determine the dynamics of A' and C excitons in monolayer and bulk WSe2 at room temperature. Besides this, we also observe the relaxation process of the holes between the two spin split states in the valence band maximum in organic super acid treated monolayer WSe2. We find that the organic super acid treatment on monolayer WSe2 does not change the peak positions of the exciton states, while those bleaching peaks' intensities increase significantly due to the enhancement of oscillator strength for exciton states, corresponding to stronger steady-state photoluminescence. This could be attributed to the strain release induced by the defect repairing effect during the organic super acid treatment process.

Abstract
Time-dependent density-functional theory molecular dynamics reveals an unexpected effect of optical excitation in the experimentally observed rhombohedral-to-cubic transition of GeTe. The excitation induces coherent forces along [001], which may be attributed to the unique energy landscape of Peierls-distorted solids. The forces drive the A_{1g} optical phonon mode in which Ge and Te move out of phase. Upon damping of the A_{1g} mode, phase transition takes place, which involves no atomic diffusion, defect formation, or the nucleation and growth of the cubic phase.

Abstract
OBJECTIVE Early allograft dysfunction (EAD) is frequent complication post-liver transplantation and is closely related to recipient's mortality and morbidity. We sought to develop a nomogram for predicting incidence of EAD. METHODS Based on multivariate analysis of donor, recipient, and operation data of 199 liver transplants from deceased donors between 2013 and 2015, we identified 5 significant risk factors for EAD to build a nomogram. The model was subjected to prospective validation with a cohort of 42 patients who was recruited between January and June 2016. The predictive accuracy and discriminative ability were measured by area under the receiver operating characteristic curve (AUC). The agreement between nomogram prediction and actual observation was showed by the calibration curve. RESULTS Incidence rate of EAD in the training set and validation cohort were 55.91% (104/199) and 54.76% (23/42), respectively. In the training set, according to the results of univariable and multivariable analysis, 5 independent risk factors including donor gender, donor serum gamma-glutamyl transpeptidase level, donor serum urea level, donor comorbidities (respiratory, cardiac, and renal dysfunction), and recipient Model for End-stage Liver Disease score were identified and assembled into the nomogram. The AUC of internal validation using bootstrap resampling and prospective validation using the external cohort of 42 patients was 0.74 and 0.60, respectively. The calibration curves for probability of EAD showed acceptable agreement between nomogram prediction and actual observation. According to the score table, the probability of EAD was under 30% when the total point tally was under 72. But when the total was up to 139, the risk of EAD increased to 60%. CONCLUSION We've established and validated a nomogram that can provide individual prediction of EAD for liver transplant recipients. The practical prognostic model may help clinicians to qualify the liver graft accurately, making a more reasonable allocation of organs.

Abstract
Objective: To investigate the relationship between ApoB/A1 ratio and the characteristics of tissue components of their left main coronary artery(LMCA)plaque. Methods: A total of 98 patients with stable angina pectoris who received chronic statin treatment underwentpercutaneous coronary intervention in the People's Hospital of Henan Province from June 2010 to June 2016 were included.We prospectively performed intravascular ultrasound virtualhistology (IVUS-VH) to their LMCA and evaluated the tissue characteristics, and the blood level of total cholesterol (TC) and low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), triglyceride(TG), LDL-C/HDL-C ratio, ApoB, ApoA1, ApoB/A1 ratio were measured, then the association of the tissue characteristics with the aboved lipids values were analyzed. Results: According to the median value of their ApoB/A1ratios (0.80), they were divided into 2 groups [high ApoB/A1 ratio (>0.80) (n=49) and low ApoB/A1 ratio (≤0.80) (n=49)]. The patients with a high ApoB/A1 ratio had alarger fibrolipid volume and a smaller fibrous volume compared to patients with a low ApoB/A1 ratio ( 17.5%±1.2% vs 9.0%±1.0%, P=0.03 and 55.1%±2.1% vs 63.9%±1.8%, P<0.01). Using multivariate linear regression analysis after adjustment for the above-mentioned confounding factors, the ApoB/A1 ratio had a significantly positive correlation with fibrolipid volume (r=0.445, β=0.29, P=0.010)and had a negative correlation with fibrous volume (r=-0.567, β=-0.32, P=0.011), suggesting that the ApoB/A1 ratio was associated with the vulnerability of the LMCA plaque. Conclusion: For the patients with stable angina pectoris and chronic treatment of statins, a high ApoB/A1 ratio is associated with a high percentage of fibrolipid volume and a low percentage of fibrous volume in LMCA lesions, suggesting that the ApoB/A1 ratios could predict the vulnerability of the LMCA plaque.

Abstract
We screened the suitable image reconstruction to observe the abdominal artery and compare the quality between the polychromatic and the monochromatic reconstruction images of the abdominal artery spectrum CT. Eighty patients underwent Gemstone CT energy spectrum imaging to obtain an abdominal artery polychromatic image (140 kVp) and a monochromatic image from 40 ~ 140 keV. The CT value of region of interest (ROI) was measured on the polychromatic image and the single energy image. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the abdominal aorta and hepatic artery were determined. The images in each group underwent image quality subjective scoring by three experienced radiologists using a blinded method. Finally, comprehensive comparisons and image quality subjective scorings were performed on the CT, SNR, and CNR values of the abdominal aorta. The obtained data were statistically analyzed by SPSS 19.0 software. When the keV value was reduced, the CT value of the abdominal artery gradually increased, and the image noise also changed. The comprehensive comparisons and subjective scorings were finalized for each single energy image based on the abdominal artery image quality objective indicators (CT value, SNR, and CNR). Results revealed that the abdominal artery image quality in the 50 ~ 60 keV monochromatic group was better compared to the polychromatic group. Furthermore, onochromatic imaging had different impacts on the abdominal aorta and hepatic artery image qualities. In different types of abdominal arterial reconstruction images obtained using abdominal energy spectrum CT conventional enhanced scanning, the image quality of the 50 ~ 60keV monochromatic reconstruction was higher when compared with the polychromatic reconstruction. Thus, it is recommended to apply the conventional reconstruction for abdominal artery energy spectrum CT scanning.

Abstract
Objective: To explored the effects of lumbar dorsal muscle damage on local lumbar vertebral bone quality. Methods: Thirty SD female rats, at age of 20 weeks, were randomly divided into three groups: control group, or say pseudo surgery group, an incision in the back were performed as CNT; bilateral erector spinal muscle group in which group bilateral lumbar erector spinal muscle were removed as RESM; castration group in which bilateral ovaries were resected as OVX.After three months, bone mineral density, microscopic CT and vertebral compression test were taken in lumbar vertebral (L4-6) in turn. Results: After three months bone mineral density in RESM group was obviously lower than the control group [(0.211±0.028) g/cm2 vs(0.253±0.021) g/cm2, P<0.01], however, there was no significant difference between OVX and RESM[(0.197±0.015) g/cm2 vs(0.211±0.028) g/cm2, P>0.05]. In microscopic CT three-dimensional reconstruction and bone histomorphometry analysis, compared with control group CNT , in the experimental groups OVX and RESM, bone trabecula of vertebral bodies were more sparse, the overall number and interconnection of trabecula were less.Especially in the OVX, osteoporotic trend of trabecular network trend is more obvious.In vertebral compression test, the maximum load, energy absorption, the maximum stress and elastic modulus in both OVX and RESM were significantly reduced (P<0.01). In the RESM the above four biomechanical parameters were significantly higher than those of OVX (P<0.05). Conclusion: Integrity and vigor of paravertebral muscles would be of great significance to maintain adjacent vertebral bone quality.Resection of lumbar dorsal muscles could lead to a significant decrease of local vertebral bone quality.Damage and atrophy of lumbar dorsal muscle could cause osteoporosis of vertebral bodies.

Abstract
Objective: To evaluate the efficacy and safety of intravenous thrombolytic therapy using reteplase in patients with acute ST-segment elevation myocardial infarction (STEMI). Method: A total of 73 hospitals from Henan province took part in this clinical trials during October 2012 to October 2014, 1 226 cases (1 014 male (82.7%), mean age 59.0 (51.0, 66.0) years) with acute STEMI received reteplase as thrombolytic agent.Reperfusion rate was judged according to the clinical symptoms, electrocardiogram, myocardial enzymes and heart rhythm, and the rate of cardiovascular events and bleeding events during hospitalization was also observed.Bleeding events were evaluated with global utilization of streptokinase and tissues plasminogen activator for occluded coronary arteries (GUSTO) criteria.Subgroup analysis was performed to compare the effects of various thrombolysis timing (time from onset to thrombolysis≤6 h or 6-12 h) on reperfusion rate, cardiovascular events and bleeding events rate. Results: The reperfusion rate was 89.3% (1 089/1 219) at 120 minutes after the thrombolysis, average recanalization time was (59.96±26.86) minutes.The reperfusion rate of ≤6 h thrombolysis group was significantly higher than in 6-12 hours group (90.3% (988/1094) vs. 80.8% (101/125), P=0.001), while in-hospital mortality (2.6%(28/1 094) and 0.8% (1/125), P=0.352) and rate of bleeding (5.9%(64/1 094) and 5.6%(7/125), P=0.910) were similar between the two groups. The total in-hospital mortality after thrombolysis was 2.4% (29/1219), which was significantly higher in failed recanalization group than in recanalization group (10.8%(14/130) vs. 1.4%(15/1089), P< 0.001). The total rate of bleeding after thrombolysis was 5.8% (71/1219), there were 3 severe bleeding cases according to GUSTO classification (0.2%), all of them were cerebral hemorrhage, and 2 out of 3 cases died. Conclusions: Reteplase use is related to high recanalization rate and low cardiovascular events and bleeding rate and our results thus show that reteplase is a safe and effective thrombolytic agent for STEMI patients.

Abstract
The refractory tungsten alloys with high ductility/strength/plasticity are highly desirable for a wide range of critical applications. Here we report an interface design strategy that achieves 8.5 mm thick W-0.5 wt. %ZrC alloy plates with a flexural strength of 2.5 GPa and a strain of 3% at room temperature (RT) and ductile-to-brittle transition temperature of about 100 °C. The tensile strength is about 991 MPa at RT and 582 MPa at 500 °C, as well as total elongation is about 1.1% at RT and as large as 41% at 500 °C, respectively. In addition, the W-ZrC alloy plate can sustain 3.3 MJ/m2 thermal load without any cracks. This processing route offers the special coherent interfaces of grain/phase boundaries (GB/PBs) and the diminishing O impurity at GBs, which significantly strengthens GB/PBs and thereby enhances the ductility/strength/plasticity of W alloy. The design thought can be used in the future to prepare new alloys with higher ductility/strength.

Abstract
Ultraviolet photodetector with p-n heterojunction is fabricated by magnetron sputtering deposition of n-type indium gallium zinc oxide (n-IGZO) and p-type nickel oxide (p-NiO) thin films on ITO glass. The performance of the photodetector is largely affected by the conductivity of the p-NiO thin film, which can be controlled by varying the oxygen partial pressure during the deposition of the p-NiO thin film. A highly spectrum-selective ultraviolet photodetector has been achieved with the p-NiO layer with a high conductivity. The results can be explained in terms of the "optically-filtering" function of the NiO layer.

Abstract
The effects of different dietary electrolyte balance (DEB) on growth performance, nitrogen (N) metabolism and some blood biochemical parameters were investigated in 2 to 3 months old growing rabbits. A total of 150 growing rabbits of 2 months age were randomly divided into five groups according to average body weight, with 30 rabbits in each group. The DEB levels of the five experimental diets were −154, −3.16, +201, +347, and +500 meq/kg of dry matter (DM), respectively. There was a 7-d adaptation period and a 23-d experimental period. The results showed that the DEB levels had a quadratic affect on the average daily feed intake (ADFI) (p<0.001). The greatest ADFI was achieved when the DEB level was +201 meq/kg DM. Fecal N (FN) content linearly decreased (0.047), while digestible N (DN), retained N (RN), efficiency of intake N converted into digestible N (DN/IN) and the efficiency of intake N converted into retained N (RN/IN) linearly increased with the DEB increase (0.020, 0.004, 0.021, and 0.049, respectively). Serum phosphorus (P) ion content linearly increased with the DEB increase (p = 0.036). The DEB had a quadratic relationship with serum anion gap (AG) (p = 0.002) and serum parathyroid hormone (PTH) content (p = 0.016). The DEB levels quadratically affected base excess (BE) in the plasma (p<0.001). In conclusion, the DEB unaffected growth performance but affected feed intake, N metabolism and some blood biochemical parameters of growing rabbits.
