Abstract
Abstract
Aims
Recent research reported that lower low-density lipoprotein cholesterol (LDL-C) is associated with more in-hospital bleeding in acute coronary syndrome (ACS) patients. However, the association between lower LDL-C levels and long-term bleeding in percutaneous coronary intervention (PCI) patients remains unclear.
Methods
A total of 10724 patients treated with PCI enrolled in ourhospital from January 2013 to December 2013. The primary endpoint was the Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding at 5 years. The secondary endpoint was intracranial hemorrhage. Taking the LDL-C value of 1.8 mmol/L (70 mg/dL) or 1.4 mmol/L (55 mg/dL) as cut-off points, patients were grouped to analyse, respectively.
Results
Among 9697 PCI patients treated with dual antiplatelet therapy finally enrolled, a total of 411 BARC type 2, 3 or 5 bleedings and 42 intracranial hemorrhage were recorded during a follow-up of 5 years. With LDL-C value of 1.8 mmol/L as cut-off point, multivariate Cox regression showed that lower LDL-C level was not associated with the risk for bleeding [hazard ratio (HR): 1.166, 95% confidence interval (CI): 0.879–1.549]. The result was consistent (HR: 1.185; 95% CI: 0.713–1.968) in a 1:4 propensity-score matching cohort (n=1285). For further study, we performed subgroup analysis which showed that lower LDL-C was not associated with the risk for bleeding in ACS (HR: 1.140; 95% CI: 0.846–1.535) or non-ACS patients (HR: 1.284; 95% CI: 0.909–1.813). With LDL-C value of 1.4 mmol/L as cut-off point, Cox regression showed that lower LDL-C level was not associated with the risk for bleeding in total population, ACS or non-ACS patients (P>0.05). The result was consistent in a 1:4 propensity-score matching cohort (n=760) (P>0.05). As for secondary endpoint, lower LDL-C level was not associated with the risk for intracranial hemorrhage whether the LDL-C value is 1.8 or 1.4 mmol/L as the cut-off point (P>0.05).
Conclusions
To the best of our knowledge, we firstly report lower LDL-C level (whether the LDL-C value is 1.8 or 1.4 mmol/L as the cut-off point) was not the independent risk factor of long-term bleeding in PCI population and ACS or non-ACS subgroup populations.

Abstract
The plant IQD gene family is responsive to a variety of stresses. In this study, we studied the structural features and functions of the gene BrIQD35 in Chinese cabbage, a member of the IQD gene family. BrIQD35 was cloned and shown to contain an IQ motif. Transient expression of BrIQD35 indicated that it was localized on the plasma membrane and was significantly upregulated under drought and salt stress in Chinese cabbage. To further identify the function of BrIQD35, it was heterologously overexpressed in Nicotiana benthamiana. Although there was no significant difference between BrIQD35-overexpressed and wild-type (WT) plants under salt stress, WT N. benthamiana showed more wilting than the BrIQD35-overexpressed plants under drought stress. Since the IQ motif has been annotated as a CaM binding site, yeast two-hybrid assays were used to explore the interaction between BrIQD35 and CaM. The results indicated that BrIQD35 interacts weakly with CaMb, but not with CaMa, suggesting that BrIQD35 may function through the Ca2+ -CaMb pathway. The findings reveal a novel gene involved in drought tolerance, which is important for plant breeding and quality improvement for Chinese cabbage.

Abstract
A patient complained of ophthalmology with poor vision in both eyes for more than 30 years and aggravation for more than 2 years. The central anterior lens capsule was found to have a conical protrusion under a slit-lamp microscope after pupil dilation in both eyes. The diagnosis was bilateral cataract and congenital anterior lenticonus. Phacoemulsification cataract extraction combined with intraocular lens implantation was performed. The visual acuity in both eyes was significantly better after surgery.

Background
Inflammation plays a crucial role in coronary atherosclerosis progression, and growing evidence has demonstrated that the fibrinogen-to-albumin ratio index (FAR) is associated with the severity of coronary artery disease (CAD). However, the long-term risk of cardiovascular events remains indistinct in patients with different level of FAR and different glycemic metabolism status. This study was to access 5-year clinical outcomes of diabetic and non-diabetic patients who underwent percutaneous coronary intervention (PCI) with different level of FAR.
Methods
We consecutively enrolled 10,724 patients with CAD hospitalized for PCI and followed up for major adverse cardiac and cerebrovascular events (MACCE) covering all-cause mortality, non-fatal myocardial infarction, non-fatal ischemic stroke and unplanned coronary revascularization. FAR was computed using the following formula: Fibrinogen (mg/dL) / Albumin (g/L). According to the optimal cut-off value of FAR, which was determined by the surv_cutpoint function of the R package survminer via RStudio software (version 2021.09.0), patients were divided into higher level of FAR (FAR-H) and lower level of (FAR-L) subgroups, and were further categorized into for groups as FAR-H with DM and non-DM, and FAR-L with DM and non-DM.
Results
5,298 patients (58.36 ± 10.36 years, 77.7% male) were ultimately enrolled in the present study. A total of 1,099 (20.7%) MACCEs were documented during the 5-year follow-up. The optimal cut-off value of FAR was 0.0783 by the surv_cutpoint function. Compared to ones with FAR-H and DM, patients with FAR-L and non-DM, FAR-H and non-DM, FAR-L and DM had decreased risk of MACCEs [adjusted hazard ratio (HR): 0.75, 95% confidence interval (CI) 0.64-0.89, p = 0.001; HR: 0.006, 95% CI 0.66-0.93, p = 0.006; HR: 0.81, 95% CI 0.68-0.97, p = 0.019]. Notably, non-diabetic patients with lower level of FAR also had lower all-cause mortality risk than those in the FAR-H/DM group (HR: 0.41, 95% CI 0.27-0.63, p < 0.001). Multivariate Cox proportional hazards regression analysis also indicated the highest risk of MACCEs in patients with FAR-H and DM than others (p for trend = 0.005). In addition, subgroup analysis revealed consistent effects on 5-year MACCE across various subgroups.
Conclusion
Diabetic patients with higher level of FAR had the worse 5-year outcomes compared with patients in other three groups. The level of FAR may help to identify high-risk individuals in this specific population.

Abstract
OBJECTIVE Emerging studies have suggested a strong link between Crohn's disease (CD) and IgA nephropathy (IgAN), but the underlying pathogenesis remains unclear. This led us to explore the common pathogenic genes for the two diseases by originally applying a bioinformatic method. MATERIALS AND METHODS The CD and IgAN datasets were downloaded from the Gene Expression Omnibus (GEO) database. The common differentially expressed genes (DEGs) of the two diseases were identified. GO and KEGG enrichment analyses for the common DEGs were further performed. Then, PPI networks were constructed to identify the hub genes. Afterwards, the receiver operating characteristic (ROC) curves were constructed to assess the diagnostic value of the hub genes. Finally, the immune infiltrations in the samples were analyzed and the correlation of the hub genes with the immune infiltration was studied. RESULTS 47 common DEGs were identified between CD and IgAN with the threshold of p-value < 0.05 and |log2FC| > 1. The top 5 GO terms and 5 KEGG pathways were displayed, and the top 10 hub genes were selected. The diagnostic value of these hub genes was evaluated by calculating the area under the ROC curves. Among the hub genes, CXCL2 was not only identified as the common hub gene, but also with the highest diagnostic value. Finally, CXCL2 was verified to be crucially correlated with the immune infiltration in the samples of CD and IgAN. CONCLUSIONS Our study identified critical pathogenic genes commonly responsible for the pathogenesis of CD and IgAN, which provided novel biomarkers and promising therapeutic targets for the two diseases. Further experimental and clinical research are needed to verify our results.

Abstract
Objectives: To explore the risk factors associated with septic cardiomyopathy and establish a predictive model of the disease based on left ventricular global longitudinal strain (LV GLS). Methods: Data from sepsis patients without a history of cardiac dysfunction who were treated in the Critical Care Department of the Northern Jiangsu People's Hospital from September, 2019 to January, 2021 were included in the analysis. The LV GLS was measured by echocardiography within 72 hours and the patients were divided into a septic myocardiopathy group (LV GLS>-17%) and a normal cardiac function group (LV GLS≤-17%). Clinical data from two groups of patients were collected for univariate analysis. The receiver operating characteristic (ROC) curves of the factors that were statistically different were drawn for exploring the diagnostic and cut-off values. The continuous variable was converted to a dichotomous variable according to the cut-off value. Multivariate logistic regression analysis of sepsis cardiomyopathy was performed to screen the risk factors and create a predictive model. The predictive model was evaluated by ROC curve analysis and the Bootstrap method and shown as a nomograph. Results: Patients in the sepsis cardiomyopathy group had higher levels of high sensitive troponin I (Hs-TnI), procalcitonin (PCT), lactate (Lac), N-terminal pro-brain atriuretic peptide (NT-proBNP), vasopressor dosing intensity (VDI) and sequential organ failure assessment (SOFA) when compared to those in the normal cardiac function group (all P<0.05). The multivariate logistic regression analysis showed that Hs-TnI≥0.131 μg/L (OR=6.71, 95%CI:2.67-16.88, P<0.001), PCT≥40 μg/L (OR=3.08, 95%CI:1.10-8.59, P=0.032), Lac≥4.2 mmol/L (OR=2.80, 95%CI:1.02-7.69, P=0.045), NT-proBNP≥3 270 ng/L (OR=2.67, 95%CI:1.06-6.74, P=0.038) were independent risk factors for septic myocardiopathy. The area under the ROC curve of the predictive model based on the four indexes up-mentioned was 0.838 (95%CI:0.766-0.910), and the C-index was 0.822 (95%CI:0.750-0.894) which indicated the utility of the nomogram. The model had a good predictive ability, accuracy and discrimination. Conclusions: Hs-TnI≥0.131 μg/L, PCT≥40 μg/L, Lac≥4.2 mmol/L and NT-proBNP≥3 270 ng/L are independent risk factors for septic myocardiopathy, and the septic cardiomyopathy predictive model constructed based on these factors has a good diagnostic performance.

Abstract
Objective: To investigate the interactive effect of hypoparathyroidism (HPTH) and type 2 diabetes mellitus (T2DM) on peritonitis in patients on peritoneal dialysis (PD). Methods: In this retrospective cohort study, all PD patients who were firstly catheterized in the peritoneal dialysis center of Guizhou Provincial People's Hospital from January 1, 2012 to December 31, 2018 were included. The characteristics of demographics, baseline clinical and laboratory data were collected, and patients were followed up until December 31, 2020. Kaplan-Meier survival curve and Cox regression analysis were used to explore the associations between the interaction of HPTH+T2DM and peritonitis. Results: A total of 270 PD patients were enrolled in this study, aged (39.9±13.2) years, including 143 males and 24 T2DM patients. These serum levels of intact parathyroid hormone (iPTH) [M(Q1, Q3)] was 268.1 (121.7, 447.0)pg/ml. After a median follow-up of 29.5 (range from 4.0 to 75.0) months, peritonitis occurred in 69 (25.6%) PD patients for the first time. After controlling for confounding factors, the interaction analysis showed that the risk of peritonitis in T2DM patients with HPTH (n=12) was 3.48 times that of non-T2DM patients without HPTH (n=180) (HR=3.48, 95%CI: 1.04-3.87, P=0.034), which was also greater than the sum of the factors alone (HR=1.35, 95%CI: 0.78-2.31 and HR=0.82, 95%CI: 0.20-3.40). The synergy index between HPTH and T2DM was 1.95, the attributable proportion of interaction was 67.6%, and the relative excess risk of interaction was 2.35. The receiver operating characteristic (ROC) curve indicated that the area under the curve of combined diagnosis of HPTH and T2DM was 0.626 (95%CI: 0.550-0.703, P=0.039). Conclusion: The positive interaction between HPTH and T2DM is an independent risk factor for peritonitis in PD patients, both of which can significantly increase the risk of peritonitis.

Abstract
Fast radio bursts (FRBs) are flashes of unknown physical origin1. The majority of FRBs have been seen only once, although some are known to generate multiple flashes2,3. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission4,5. Recently, the discovery6 of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths6. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system7. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts.

Abstract
OBJECTIVES To investigate the prevalence of sarcopenia and dysphagia in nursing homes and to analyze the associations between sarcopenic parameters and dysphagia. DESIGN A cross-sectional study. SETTING Nursing homes in Chengdu, Sichuan, China. PARTICIPANTS The study included 365 participants (122 men and 243 women) aged 60 years or older who could walk independently or with walking aids for at least 50 meters. MEASUREMENTS Dysphagia was defined by the water swallow test and sarcopenia and its components were evaluated by the criteria of the Asian Working Group for Sarcopenia, 2019. The values and percentages of sarcopenia associated parameters in relation to dysphagia were analyzed in both male and female residents. The Benjamini-Hochberg method was used to adjust for multiple comparisons. The relationship between sarcopenic components and dysphagia was analyzed using multivariate logistic regression analysis by sex. RESULTS A total of 365 residents (mean age: 84.28 years; 122 men and 243 women) were included in the study. Sarcopenia was diagnosed in 63.0% (n=230) and dysphagia in 75.3% (n = 275) of residents. For men, the percentage of sarcopenia was higher in residents with dysphagia. However, the sarcopenia percentage did not differ significantly between women with and without dysphagia. In both men and women, the handgrip strength (HGS) values were significantly lower in the dysphagic residents. The calf circumference (CC) value and appendicular skeletal muscle index (ASMI) were significantly lower in dysphagic men, while the SARC-CalF scores were higher. In women, the SPPB score was lower in residents with dysphagia. Furthermore, multivariate logistic regression analysis showed that low calf circumference (OR 4.415, 95% CI 1.561-12.490) and sarcopenia (OR 2.968, 95% CI 1.121-7.858) were significantly associated with dysphagia in men after adjusting for co-factors. CONCLUSION There is a high percentage of both dysphagia and sarcopenia in nursing home residents in West China. Low calf circumference and sarcopenia had strong associations with dysphagia among male nursing home residents.

Abstract
Starch is the most important energy source in corn-based diets for broiler chickens, however, some proportion of dietary starch may be partially digested, leading to a decrease in feed utilisation. Therefore, supplementing exogenous amylase might be a feasible way to improve the utilisation of dietary starch for poultry. This study investigated the effects of exogenous α-(1,4)-amylase supplementation on the utilisation of corn starch and glucose metabolism in broiler chickens. A total of 560, 4-d-old Arbour Acres plus male broiler chicks were randomly divided into five treatment groups and fed a corn-soybean meal diet supplemented with 0, 400, 600, 800 and 1 200 U/kg α-(1,4)-amylase to evaluate growth. The growth performance, nutrient digestibility coefficients, digestive enzyme activity, glucose transporter transcription and cecal microbiota composition were evaluated in this study. Starch digestibility coefficient showed a quadratic response to α-(1,4)-amylase at 14 d and 42 d (P < 0.05). However, the endogenous α-amylase activity in jejunal content was linearly decreased (P = 0.045). Also, exogenous α-(1,4)-amylase linearly decreased ileal Na+-dependent glucose and galactose transporter 1 mRNA expression at 42 d (P < 0.001). Exogenous α-(1,4)-amylase generated higher insulin and glucagon serum concentrations in fasted birds (P < 0.05) and following re-feeding for 2 h (P < 0.001). BW gain and feed intake were strongly positively correlated with starch digestibility coefficient at both 14 d (r = 0.87) and 42 d (r = 0.91); whereas, the relative weight of the gizzard was weakly negatively correlated with starch digestibility coefficient (r = -0.35). The relative abundance of Unclassified_Bacillaceae was moderately positively correlated (r > 0.50) while Oscillospira, Ornithobacterium and Unclassified_Barnesiellaceae were moderately negatively correlated (-0.50 < r -0.39) with starch digestibility coefficient. In conclusion, exogenous α-amylase modulates metabolic function by increasing insulin and glucagon concentrations, influenced gut microbiota which may impact starch digestibility in the jejunum and ileum. The results of this study showed that excessive addition of exogenous α-(1,4)-amylase was not beneficial for the utilisation of starch in broiler chickens. Supplement more than 600 U/kg α-(1,4)-amylase inhibited glucose transporters, decreases the coefficients of starch and organic matter digestibility in the small intestine to a varying degree, thereby limiting the growth performance of broiler chickens.

Abstract
Because of their high specificity and low side effects, protein drugs possess a substantial global market. However, the low bioavailability of protein is still a major obstacle to their expanded applications, which is expected to be answered with proper protein formulations. Taking corneal neovascularization (CNV) as an example, we demonstrated a co-assembled system of hexa-histidine and Ava (Avastin) with metal ions (HmA@Ava) could cross the cornea, the most important bio-barrier during the treatment of most diseases of the anterior segment in clinics. We found that the nanosized HmA@Ava efficiently encapsulated Ava with impressive loading capacity without destroying the bioactivity of Ava and assisted Ava penetration through the corneal barriers to effectively inhibit CNV development in an alkali burn rat model with sustained and pH-dependent Ava release. Our results suggested that the co-assembled strategy of protein and HmA is a proper formulation to protein drugs, with promising penetration ability to deliver protein across bio-barriers, which could open a path for topical administration of protein drugs for treatment of various ocular diseases and hold enormous potential for delivery of therapeutic proteins not only for ocular diseases but also for other diseases that require protein treatment. HmA@Ava can bring protein drug, Ava, across over the primary bio-barrier of the anterior segment and efficiently treat CNV. HmA@Ava was nanoparticles, with impressive loading capacity without destroying bioactivity of Ava and strong pH-dependent release. HmA can open a path for the treatment of eye diseases and hold huge potential to protein drugs to other diseases.

Abstract
Introduction/Objective
Composite classic Hodgkin lymphoma and follicular lymphoma (CHLFL), defined as CHL and FL occurring simultaneously at the same site, is rare and poorly understood. While both Hodgkin/Reed-Sternberg (HRS) cells and FL are thought to be derived from germinal center B-cells, the relationship between CHL and FL when coexistent is unclear. Here, we present two cases of CHLFL and show that the CHL and FL components have a clonal relationship by FISH.
Methods/Case Report
Case #1 is a 50-year-old man with abdominal and mediastinal lymphadenopathy. An excised mesenteric lymph node showed two distinct components diagnostic for FL, grade 1-2 and CHL. Case #2 is a 63-year- old woman with a history of FL with transformation to diffuse large B-cell lymphoma. Cytogenetic studies showed a complex karyotype with an add(9p), del(10q), and trisomy 16. Post-treatment imaging revealed left axillary adenopathy. An excised axillary lymph node showed CHL with peripheral areas of FL, grade 3A.
Both cases had areas of typical FL with BCL2-positive phenotype and no significant CD30/CD15 expression. HRS cells were CD45/CD20-negative, expressed CD30 (strong), CD15, and PAX5, and were present in a mixed inflammatory background. No EBV RNA was present by in situ hybridization. Interestingly, HRS cells in case #1 expressed both BCL6 and BCL2.
FISH was performed in both cases. Case #1 had a BCL2 rearrangement in 48% of FL nuclei and in 100% of HRS cells. In case #2, targeted probes were used based on prior cytogenetic results. Here, 47% of FL nuclei and 44% of HRS cells had a 16p duplication; additionally, 32% of HRS cells had an unbalanced IGH rearrangement with loss of the IGH variable region, suggesting possible clonal evolution. No rearrangement of BCL2 or BCL6 was present.
An additional 27 CHLFL cases from the literature were reviewed. CHLFL was mostly nodal and occurred in late adulthood in patients with or without a history of FL. It presented at advanced clinical stage, with a 5-year overall survival of 22%. BCL2 expression in HRS cells was common. Bone marrow involvement was 45% (5/11) and consisted of FL exclusively. Five of six tested cases demonstrated BCL2/IGH rearrangement in both FL and HRS cells.
Results (if a Case Study enter NA)
NA
Conclusion
Composite CHL and FL are often clonally related and may share a common progenitor B-cell origin – likely a germinal center B-cell – from which additional genetic abnormalities are acquired to develop two distinct lymphomas.

Abstract
Background
Evidence is lacking on the choice between coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) in the specific setting of non-ST-segment elevation acute coronary syndrome (NSTE-ACS), especially for complex cases with three-vessel coronary artery disease (TVD).
Purpose
To compare PCI and CABG in NSTE-ACS patients with TVD; to explore effects of age and sex on outcomes of different revascularisation strategies.
Methods
The present study was a post hoc analysis of data from a single-centre prospective cohort of 8,943 patients with TVD [(angiographically confirmed stenosis of ≥50% in all three main epicardial coronary arteries (left anterior descending, left circumflex, and right coronary arteries), with or without left main lesion]. Patients were consecutively enrolled from April 2004 to February 2011 to evaluate their prognosis after receiving three different treatments. The study contained 2,812 patients (PCI, n=1,559; CABG, n=1,253) after excluding 1,489 with ST-segment elevation myocardial infarction, 3,532 with stable coronary artery disease, and 1,110 receiving conservative treatment.
The patients were divided into three age groups and two sex groups. Subgroup analyses were performed according to presence of diabetes, pre-procedural synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score, and presence of left main lesion. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause death, myocardial infarction and stroke.
Results
During a median follow-up of 6.7 years, the risk of MACCE was significantly lower after CABG than after PCI in all patients (HR=0.6764, 95% CI: 0.5528–0.8277), two younger age groups (<65 years: HR=0.6617, 95% CI: 0.4947–0.8852; 65–74 years: HR=0.6997, 95% CI: 0.5124, 0.9556), and male (HR=0.6682, 95% CI: 0.5263–0.8482) (Figure 1). No significant interaction between age and revascularization strategies was observed, neither was it between sex and revascularization strategies. Notably, compared with PCI, CABG was associated with significantly higher risk of MACCE in women ≥75 years of age (HR=3.2716, 95% CI: 1.4213–7.5308, interaction p with sex=0.0007, interaction p with age=0.0024). Effects of age and sex on outcomes of different revascularisation strategies remained neutral regardless of patients' diabetic status, pre-procedural SYNTAX score, and presence of left main lesion (Figure 2).
Conclusion
CABG is superior to PCI in terms of MACCE regardless of patients in most NSTE-ACS patients with TVD except women ≥75 years of age. However, we found no significant age- or sex-related difference in prognosis of CABG relative to PCI.

Abstract
Abstract
Background
At present, it is worth noting that there is a lack of biomarker for the residual risk of thrombosis in patients underwent percutaneous coronary intervention (PCI). D-dimer is an important thrombus marker and widely used in clinical practice.
Purpose
We aim to investigate the correlation between D-dimer and the risk of stent thrombosis (ST) after PCI.
Method
This is a prospective, observational study of 10,724 patients who underwent PCI. The primary endpoint was ST, which was defined according to the Academic Research Consortium including definite, probable, and possible.
Results
Finally, 8565 patients were included in this study after excluding 2159 people with missing D-dimer data or lost to follow-up. After 2-year follow-up, there were 77 ST occurred. D-dimer levels were significantly higher in the ST group (0.33 [0.28, 0.56] μg/ml) than in the non-ST group (0.28 [0.20, 0.41] μg/ml) (P=0.001). Kaplan–Meier survival curve analysis showed that patients with high D-dimer levels had higher cumulative ST according to the median D-dimer level (0.28 μg/ml) in the total population, acute coronary syndrome (ACS) subgroup, and stable coronary artery disease (SCAD) subgroup, respectively. (log-rank test, all P<0.001) (Figure 1). After multivariate-adjusted cox hazard analysis, high D-dimer levels (≥0.28 μg/ml) were significantly associated with ST in the total population (hazard ratio [HR]: 2.25, 95% confidence interval [CI]: 1.29–3.95, P=0.005) and ACS subgroup (HR: 2.13, 95% CI: 1.09–4.16, P=0.027); however, we did not find a statistically significant in the SCAD subgroup (HR: 2.56, 95% CI: 0.92–7.1, P=0.072).
Conclusion
In this real world and large sample data study, we reported for the first time that D-dimer was strong independent thrombosis biomarker in patient who underwent PCI. In the future, we may use D-dimer to guide individualized antithrombotic therapy after PCI.

Abstract
Abstract
Background
Management of dyslipidemia is the primary recommend in current guidelines in patients with coronary heart disease (CHD). Despite intense statins therapy, patients with low-density lipoprotein cholesterol (LDL-C) level of more than 1.8 mmol/L still have residual cholesterol risk. Premature triple-vessel disease (PTVD) is a severe CHD. Recent studies have established that both residual cholesterol risks and PTVD were associated with adverse cardiovascular events. Niemann-Pick C1-like 1 (NPC1L1) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) is involved in exogenous cholesterol absorption and endogenous cholesterol synthesis respectively, which play a vital part on dyslipidemia.
Purpose
The present study aimed to investigate the association between NPC1L1 and HMGCR gene polymorphisms and residual cholesterol risk in patients with PTVD.
Methods
A total of 609 PTVD patients treated with statins were consecutively enrolled from April 2004 to February 2011. Residual cholesterol risk was defined as low-density lipoprotein cholesterol (LDL-C) >1.8 mmol/L. According to LDL-C levels, the patients were divided into two groups: residual cholesterol risk group (n=521, >1.8 mmol/L) and non-residual cholesterol risk group (n=88, LDL-C ≤1.8 mmol/L). Four single nucleotide polymorphisms (SNP) of NPC1L1 gene including rs11763759, rs4720470, rs2072183 and rs2073547 and three SNPs of HMGCR gene including rs12916, rs2303151 and rs4629571 were genotyped.
Results
After adjusted for age and sex, multivariate logistic regression analysis showed that rs12916 of HMGCR gene was associated with 2.082 times higher residual cholesterol risk in recessive model (OR: 2.082, 95% CI: 1.156–3.749, P=0.015), and the homozygous TT of rs12916 (OR: 2.262, 95% CI: 1.155–4.429, P=0.017) was associated with 2.262 times higher residual cholesterol risk in codominant model while there was no significant association for the heterozygous CT of rs12916 in codominant model (OR: 1.140, 95% CI: 0.678–1.917, P=0.621). There was no significant association between the SNPs of NPC1L1 gene and residual cholesterol risk in various models (P>0.05).
Conclusions
We reported for the first time that the rs12916 on HMGCR gene were associated with residual cholesterol risk in patients with PTVD, providing new insight in genetic treatment in dyslipidemia.

Abstract
1. The influence of glucose oxidase (GOD) supplementation on growth, gut inflammation and its compensatory effects in broilers was investigated before and after heat stress.2. Before heat stress, one-day-old broilers were divided into two groups: the control (CON) and GOD (100 g/t complete feed) groups. On d 21, the CON group was equally divided into CON1 and CON2 groups, and heat stress (35°C) was applied to the CON2 and GOD groups for 8 h/day to the end of the study, d 27 of age. The chickens were either killed before heat stress and 2 d after heat stress for the determination of cytokines in the liver and ileum, serum antioxidant enzymes and ileal microbiota. Growth performance was determined before and 7 d after heat stress.3. The GOD decreased Clostridiales and Enterobacteriaceae families of bacteria and increased ileal nuclear factor-κB, interleukin-1β, and interferon-γ (P < 0.05) before heat stress. The broilers exhibited compensatory effects, including increases in ileal sirtuin-1, heat shock protein 70 expression, liver nuclear factor erythroid 2-related factor 2 content, serum total antioxidant capacity and glutathione peroxidase level (P < 0.05). At 2 d after heat stress, inflammatory factors were increased in both the CON2 and GOD groups, but the levels were lower in the GOD than CON2 (P < 0.05). On d 7 after heat stress, GOS alleviated heat stress induced growth retardation (P < 0.05).4. These data suggested that GOD supplementation in broiler diets before heat stress stimulated intestinal oxidative stress and produced a compensatory response, which prevented a rapid increase in intestinal inflammatory factors and helped to maintain growth performance under heat stress.

Abstract
Objective: To investigate the clinicpathological, immunohistochemical and molecular genetic features of malignant mixed mesodermal tumor (MMMT) in the female reproductive system. Methods: To analyze its histopathological characteristics, we performed a retrospective review of the MMMT cases diagnosed at PLA General Hospital, Beijing, China during 2005-2019 using its surgical and pathological databases. EnVision immunohistochemical staining was used to detect the expression of ER, PR, p16, p53 and MMR proteins. Results: Fifty cases were conformed to the diagnosis, including 29 cases originated in the uterus, 16 cases in ovary, 4 cases of synchronous occurrence in uterus and ovary, 1 case in cervix. The tumor was histologically composed of two components, namely carcinoma and sarcoma ones, with clear borderline or blend mutually. The proportion of cancer component in the whole tumor ranged from 5%-90%. The proportion of carcinoma was more than 50% in 76% of the cases, and less than 50% in 24% of cases, including 2 cases with<10% of carcinoma. In the cases of primary uterine MMMT, the main carcinoma type was high grade endometrioid carcinoma (55%, 16/29). In ovarian MMMT, the main carcinoma type was serous carcinoma (12/16), while that of cervical MMMT was squamous cell carcinoma. The others were clear cell carcinoma or the undifferentiated carcinoma. There was one carcinoma type in most cases, only 7 cases had two carcinoma types. Homologous sarcomas, including stromal sarcoma, leiomyosarcoma and high-grade spindle cell sarcomas, were more commonly found in uterine MMMT (72.4%, 21/29). While heterogenic sarcomas, including chondrosarcoma, osteosarcoma and rhabdomyosarcoma, were more commonly noted in ovarian MMMT (12/16) than MMMT of other sites. There were 10 cases that consisted of two types of sarcomas. The synchronous MMMT of uterus and ovary had similar morphology and the types of carcinoma and sarcoma. The tumor cells that spread or metastasized to lymph node, omentum, intestinal wall or skin were all carcinoma cells, and were morphologically consistent with the original tumors. Immunohistochemically, ER and PR were both negative (23/25 in uterine, 8/10 in ovarian tumors). p16 was strongly positive (11/11 in uterine tumors, and 6/6 in ovarian tumors), with similar expression patterns in the carcinoma and sarcoma components. p53 showed mutant-type staining (64%, 21/33) and expressed synchronously in carcinoma and sarcoma components. p53 mutation was found in 35% cases of endometrial carcinoma and 46.7% cases of non-endometrial carcinoma. p53 mutation was also found in only 31.8% cases of heterogenic sarcomas, but in 50% of non-heterogenic sarcomas. Twenty-eight cases (28/33, 85%) presented intact mismatch repair proteins, while 5 cases (5/33, 15%) presented deficient mismatch repair proteins. Conclusions: MMMT in female reproductive system is a rare high-grade biphasic tumor with complex and diverse morphology. The immunohistochemical features are characterized by negative ER/PR and strongly positive p16, mostly mutant p53 and proficient mismatch repair proteins. The patients with a high FIGO stage have worse prognosis.
