Abstract
BACKGROUND The evidence for the comparative effectiveness and safety of ticagrelor versus clopidogrel in older patients with acute coronary syndrome (ACS) is limited, especially in the acute phase of ACS. This study aimed to compare the in-hospital outcomes of ticagrelor versus clopidogrel in older patients with ACS. METHODS Hospitalised ACS patients aged ≥75 years who were recruited to the Improving Care for Cardiovascular Disease in China-ACS project between November 2014 and December 2019 and received aspirin and P2Y12 receptor inhibitors within 24 h after first medical contact were included. The primary outcomes were in-hospital major adverse cardiovascular events (MACE) and major bleeding. Multivariable Cox regression was performed to evaluate the comparative effectiveness and safety of ticagrelor and clopidogrel. Inverse probability of treatment weighting (IPTW) and propensity score matching analyses were performed to evaluate the robustness of the results. RESULTS Of 18,244 ACS patients, 18.5% received ticagrelor. Multivariable-adjusted analysis revealed comparable risks of in-hospital MACE between patients receiving ticagrelor and clopidogrel (hazard ratio [HR] 1.12, 95% confidence interval [CI] 0.92-1.35). However, ticagrelor use was associated with 45% higher risk of in-hospital major bleeding compared with clopidogrel use (HR 1.45, 95% CI 1.09-1.91). Similar results were found in the IPTW analysis. CONCLUSIONS ACS patients aged ≥75 years receiving ticagrelor during the acute phase had similar risk of in-hospital MACE, but higher risk of in-hospital major bleeding compared with those receiving clopidogrel. More evidence is needed to guide the use of P2Y12 receptor inhibitors during hospitalisation in older patients with ACS. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Abstract
The skull defects are challenging to self-heal, and autologous bone graft repair has numerous drawbacks. The scaffolds for the rapid and effective repair of skull defects have become an important research topic. In this study, polyvinyl alcohol (PVA)/β-tricalcium phosphate(β-TCP) composite scaffolds containing icariin (ICA) were prepared through direct-ink three-dimensional (3D) printing technology. β-TCP in the composite scaffold had osteoconductive capability, and the ICA molecule had osteoinductive capacity. The β-TCP and ICA components in the composite scaffold can enhance the capability to repair skull defects. We show that ICA exhibited a slow-release behaviour within 80 days. This behaviour helped the scaffold to continuously stimulate the formation of new bone. The results of in vitro cell compatibility experiments showed that the addition of ICA molecules contributed to the adhesion and proliferation of MC-3T3-E1 cells. The level of alkaline phosphatase secretion demonstrated that the slow release of ICA can promote the osteogenic differentiation of MC-3T3-E1 cells. The introduction of ICA molecules accelerated the in situ bone regeneration in in vivo. It is concluded that the 3D-printed PVA scaffold with β-TCP and ICA has a wide range of potential applications in the field of skull defect treatment.

Abstract
In this study, the hydroxy fatty acid dehydrogenase CLA-DH from Lactobacillus plantarum p-8 and its four mutant variants were expressed in Escherichia coli Rosetta (DE3). UV spectrophotometry was employed to verify the catalytic power of the purified CLA-DH to convert ricinoleic acid into 12-oxo-cis-9-octadecenoic acid in the presence of oxidized nicotinamide adenine dinucleotide (NAD+). The optimum reaction temperature for CLA-DH was 45°C, with a maintained stability between 20°C and 40°C. The optimal pH for CLA-DH catalytic activity was 6.0-7.0, with a maintained stability at a pH range of 6.0-8.0. In addition, Fe3+ promoted enzyme activity, whereas Cu2+, Zn2+, and Fe2+ inhibited enzyme activity (P < 0.05). The Km, Vmax, Kcat, and Kcat/Km of CLA-DH were determined as 2.19 ± 0.34 μM, 2.06 ± 0.28 μM min-1, 2.00 ± 0.27 min-1, and 0.92 ± 0.02 min-1μM-1, respectively. Site-directed mutagenesis and molecular dynamics simulations demonstrated that both Tyr156 and Ser143 residues play significant roles in the catalysis of CLA-DH, and its solubility is affected by Lys160 and Asp63. Moreover, Gas chromatography determined that recombinant CLA-DH could be successfully applied to Conjugated linoleic acids production.

Abstract
Objective: To investigate the correlation between patatin-like phospholipase domain-containing 3 (PNPLA3) rs738409 and transmembrane 6 superfamily member 2 (TM6SF2) rs58542926 gene polymorphisms and the incidence of primary liver cancer in the Han population of China's Northeast region. Methods: A case-control study was used to enroll 521 patients with primary liver cancer as the case group and 164 healthy people as the control group. The case group was divided into groups with and without liver cirrhosis according to etiology. The polymerase chain reaction (PCR) method was used to detect the genetic polymorphisms of PNPLA3 rs738409 and TM6SF2 rs58542926, respectively. Results: Compared with the control group, the frequency distribution of PNPLA3 rs738409 G allele in the case group was significantly different (OR = 1.583, P = 0.001). Further grouping showed that there was no statistically significant difference between the control and hepatitis C-related liver cancer group (P = 0.161), but there were significant differences in other groups (P < 0.05). Compared with the control group, the frequency of TM6SF2 rs58542926 T allele in the case group was significantly higher than that in the control group (OR = 1.759, P = 0.048). After grouping, the frequency of CT/TT genotype in the liver cancer group combined with liver cirrhosis and the T allele frequency in the alcohol-related liver cancer group had statistically significant difference (P = 0.045 and 0.032, respectively) when compared with control group. The patients were divided into CG/GG group and CC group, and CT/TT group and CC group according to whether they carried PNPLA3 rs738409 G allele, and TM6SF2 rs58542926 T allele. Results showed that there were no statistically significant differences in liver enzyme indexes, albumin (ALB), total bilirubin (TBIL), alpha-fetoprotein (AFP) and fasting blood glucose between CG/GG group and CC group, and CT/TT group and CC group. The patients with liver cirrhosis in the case group were divided into≥7 groups and < 7 groups according to the Child-Pugh score. Results showed that there were no statistically significant difference in the Child-Pugh score between PNPLA3 rs738409 CG/GG group and CC group patients and TM6SF2 rs58542926 CT/TT group and CC group patients (P > 0.05). Conclusion: PNPLA3 rs738409 and TM6SF2 rs58542926 gene polymorphisms are correlated with the occurrence of primary liver cancer in the Han population of China's Northeast region. PNPLA3 rs738409 and TM6SF2 rs58542926 gene polymorphisms have no effect on indexes' such as liver enzymes, ALB, TBIL, AFP and FBS in primary liver cancer..

Abstract
OBJECTIVES/HYPOTHESIS Intracellular entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) depends on the interaction between its spike protein with the cellular receptor angiotensin-converting enzyme 2 (ACE2) and depends on Furin-mediated spike protein cleavage and spike protein priming by host cell proteases, including transmembrane protease serine 2 (TMPRSS2). As the expression of ACE2, TMPRSS2, and Furin in the middle and inner ear remain unclear, we analyzed the expression of these proteins in mouse ear tissues. STUDY DESIGN Animal Research. METHODS We performed immunohistochemical analysis to examine the distribution of ACE2, TMPRSS2, and Furin in the Eustachian tube, middle ear spaces, and cochlea of mice. RESULTS ACE2 was present in the nucleus of the epithelium of the middle ear and Eustachian tube, as well as in some nuclei of the hair cells in the organ of Corti, in the stria vascularis, and the spiral ganglion cells. ACE2 was also expressed in the cytoplasm of the stria vascularis. TMPRSS2 was expressed in both the nucleus and cytoplasm in the middle spaces, with the expression being stronger in the nucleus in the mucosal epithelium of the middle ear spaces and Eustachian tube. TMPRSS2 was present in the cytoplasm in the organ of Corti and stria vascularis and in the nucleus and cytoplasm in the spiral ganglion. Furin was expressed in the cytoplasm in the middle ear spaces, Eustachian tube, and cochlea. CONCLUSIONS ACE2, TMPRSS2, and Furin are diffusely present in the Eustachian tube, middle ear spaces, and cochlea, suggesting that these tissues are susceptible to SARS-CoV-2 infection.

Abstract
OBJECTIVES/HYPOTHESIS Human laryngeal squamous cell carcinoma (LSCC) is a malignancy that was discovered originally in the epithelial tissue of laryngeal mucosa. However, the underlying molecular mechanism is still not clear. In this study, we aimed to investigate the potential molecular mechanisms of TSR2 in the LSCC cell apoptosis. STUDY DESIGN The expression of TSR2 was first analyzed in LSCC tissues. Then functional effects of TSR2 on Hep-2 and AMC-HN-8 cell lines were performed by overexpression pcDNA3.1-TSR2. METHODS We investigated the expression level of TSR2 in LSCC tissues and cells by performing quantitative real-time polymerase chain reaction (qRT-PCR). The pcDNA3.1-TSR2 was constructed to explore the effect of overexpressing TSR2 in Hep-2 cells and AMC-HN-8 cells. We further investigated the effect of overexpressing TSR2 on cell apoptosis-related protein and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) p65 nuclear translocation through Western blot and terminal dUTP nick end-labeling assays. RESULTS We found that TSR2 was downregulated in LSSC tissues and cells compared with the controls, and the overexpression of TSR2 in Hep-2 and AMC-HN-8 cells could promote cell apoptosis and related apoptosis proteins. The Western blot/qRT-PCR data further indicated that overexpression of TSR2 in Hep-2 and AMC-HN-8 cells could lead to a block of NF-κB signaling pathway via decreasing nuclear NF-κB p65 and increasing cytoplasm NF-κB p65. Moreover, overexpression of TSR2 significantly inhibited the phosphorylation of IκBα and IKKα/β. CONCLUSIONS The results indicated that TSR2-induced apoptosis was mediated by inhibiting the NF-κB signaling pathway, which may provide an effective target in gene therapy for LSCC.

Abstract
We describe a case of a fetus with an ectopic connection of the ductus venosus to a dilated coronary sinus that was diagnosed at ShengJing Hospital of China Medical University. A dilated coronary sinus was initially detected with prenatal echocardiography. Neither a persistent left superior vena cava nor an anomalous pulmonary venous connection was present. After comprehensive examination, we discovered that the ductus venosus had an abnormal course draining into the coronary sinus. The postnatal outcome of this fetus was good. Once a dilated coronary sinus is confirmed, further ultrasound evaluation should be performed to search for a potential cause.

Abstract
Abstract
Normal DNA replication starts following the stepwise recruitment of replication initiators to assemble Mini-chromosome Maintenance (MCM) 2-7 protein complexes at an adequate amount of DNA replication origins. Under normal conditions, the monoubiquitination of Fanconi Anemia (FA) group D2 protein (FANCD2) occurs in each S-phase of cell cycle, which is the basal level of FANCD2 monoubiquitination. However, little is known regarding the roles of this basal level of monoubiquitinated FANCD2. Here, we report that monoubiquitnated FANCD2 in each S-phase of a given cell cycle can interact with replication origins and MCM3. In normally growing cells, the presence of non-monoubiquitinated FANCD2 or mutant MCM3 lacking AA 477-480 responsible for interacting with FANCD2 can lead to an insufficient amount of licensed origins ready for firing and, thereby, enlarged intervals between the fired origins. These results demonstrate that in normally cycling cells, the monoubiquitinated FANCD2 is required to maintain an enough number of licensed origins to initiate a normal DNA replication. This finding is the first to provide insights into how FANCD2 functions under normal conditions of cell cycle to maintain genome stability, as well as its resulting implications in the strategic improvement for the fight against human cancer. This study is funded by NIH RO1CA136532.

Abstract
BACKGROUND & AIMS The cause of hepatic failure in the terminal stages of chronic injury is unknown. Cellular metabolic adaptations in response to the microenvironment have been implicated in cellular breakdown. METHODS To address the role of energy metabolism in this process we studied mitochondrial number, respiration, and functional reserve, as well as cellular adenosine-5'-triphosphate (ATP) production, glycolytic flux, and expression of glycolysis related genes in isolated hepatocytes from early and terminal stages of cirrhosis using a model that produces hepatic failure from irreversible cirrhosis in rats. To study the clinical relevance of energy metabolism in terminal stages of chronic liver failure, we analyzed glycolysis and energy metabolism related gene expression in liver tissue from patients at different stages of chronic liver failure according to Child-Pugh classification. Additionally, to determine whether the expression of these genes in early-stage cirrhosis (Child-Pugh Class A) is related to patient outcome, we performed network analysis of publicly available microarray data obtained from biopsies of 216 patients with hepatitis C-related Child-Pugh A cirrhosis who were prospectively followed up for a median of 10years. RESULTS In the early phase of cirrhosis, mitochondrial function and ATP generation are maintained by increasing energy production from glycolytic flux as production from oxidative phosphorylation falls. At the terminal stage of hepatic injury, mitochondria respiration and ATP production are significantly compromised, as the hepatocytes are unable to sustain the increased demand for high levels of ATP generation from glycolysis. This impairment corresponds to a decrease in glucose-6-phosphatase catalytic subunit and phosphoglucomutase 1. Similar decreased gene expression was observed in liver tissue from patients at different stages of chronic liver injury. Further, unbiased network analysis of microarray data revealed that expression of these genes was down regulated in the group of patients with poor outcome. CONCLUSIONS An adaptive metabolic shift, from generating energy predominantly from oxidative phosphorylation to glycolysis, allows maintenance of energy homeostasis during early stages of liver injury, but leads to hepatocyte dysfunction during terminal stages of chronic liver disease because hepatocytes are unable to sustain high levels of energy production from glycolysis.

Abstract
OBJECTIVE To evaluate the treatment efficacy and tolerance of anti-human T lymphocyte porcine immunoglobulin (p-ALG) plus cyclosporine A (CsA) in acquired severe aplastic anemia (SAA). METHOD Forty-eight SAA patients [31 males and 17 females; 17 with very SAA (VSAA)] were treated with p-ALG plus CsA and were analyzed retrospectively according to early mortality, response rate and quality, survival rate, toxicity, and complications. They were stratified further by gender, age, disease severity, interval from diagnosis to treatment, and preexisting infections. RESULT The median age was 28 years (range 13-64). The interval from diagnosis to treatment was 45 days. The median neutrophil count was 0.178 × 10⁹/l. The overall response was 83.3% (54.2% complete and 29.2% partial) with a 90-day median time (range 23-380), and 10.4% died of infection within 30 days. The 1.5-year survival was 87.5%. vSAA patients had less response, a higher early mortality, and less survival (64.7, 29.4, 51.8%) compared to SAA patients (93.5, 0, and 100%, respectively; p < 0.05). Groups with different age, gender, intervals between diagnosis and treatment, and preexisting infections had the same response. Mild toxicities were observed. CONCLUSION p-ALG plus CsA is a reliable and well-tolerated treatment for SAA, and it has the great advantage of a much lower cost compared to horse/rabbit ATG. VSAA was a poor predictive factor for the response rate.

Abstract
OBJECTIVE To observe the effect of acupuncture on cortical functional areas of the patient with ischemic stroke activated by the index finger motion. METHODS The cortical magnetic resonance imaging (fMRI) were carried out in 15 cases of ischemic stroke during the index finger motion at acupuncture or non-acupuncture. The distribution of the cortical functional areas activated and the size of the activated region and the intension of signals were measured. RESULTS The finger motion with no acupuncture could activate the contralateral primary somatomotor area (M1), contralateral premotor area (PMA) and contralateral first somatosensory area (S1). The finger motion with acupuncture could activate the same areas and also activate ipsilateral M1, focus area contralateral superior parietal lobule, contralateral superior temporal gyrus, and contralateral insular lobe, etc.. Both the area of the activated region and the minimum signal in the finger motion with acupuncture were statistically significantly larger than those in finger motion with no acupuncture. CONCLUSION Rehabilitation of motor functions of the patient with ischemic stroke by acupuncture is related with improvement of blood circulation functional area in the cortex.

Abstract
OBJECTIVE To observe and estimate the distribution the changes of histology and biochemical parameters in retina of the patient with diabetic retinopathy. METHODS Retinas were divided into quadrants and the lesions of diabetic retinopathy were compared among quadrants. the vasculature was isolated by trypsin-digest, homogenates taken from temporal and nasal quadrant were used to explore regional differences in the expression of Glut-1, PKCbeta and activity of caspase1. RESULTS Microaneurysms, acellular capillaries and pericytes ghosts were significantly increased in the temporal retina than in the nasal retina. Activity of the pro-inflammatory protease, caspase1, was the only biochemical abnormality which was found significantly difference between quadrants. Glut-1 expression was decreased in diabetes, but there was no significant difference between quadrants. Expression of PKCbeta in both temporal and nasal retina was tended to be greater in diabetic than in non diabetic patients. CONCLUSION Retinal microvascular disease does not develop uniformly across the retina, even the different regions are exposed to the same level of hyperglycemia. Regional differences play an important role in the response of the retinal microvasculature to hyperglycemia.

Abstract
BACKGROUND/AIMS A large, sustained increase in acinar [Ca2+]i may play a key role in the pathogenesis of acute pancreatitis. Many mechanisms which lead to cell damage in vitro and pancreatitis in vivo, such as free radicals or supraphysiological cerulein concentrations, cause a rapid increase in [Ca2+]i in pancreatic acinar cells. Little is known about why [Ca2+]i increases in some instances stimulate secretion and in other instances initiate cell death. So far, [Ca2+]i increases were thought to represent physiological signals when they occurred as oscillations at the single cell level. METHODOLOGY This paper reviews recent literature and our own original research about the role of calcium in the function of pancreatic acinar cells and the development of pancreatitis. RESULTS Recent studies showed that exposure of acinar cells to free radicals not only caused a bulk increase in [Ca2+]i but also resulted in calcium oscillations which had a lower frequency than, but similar amplitude to oscillations occurring after physiological stimuli. The absolute increase in [Ca2+]i did not definitely determine the cellular response. Instead, the duration of [Ca2+]i increase may have been more important. In contrast to previous belief of a direct relationship between [Ca2+]i oscillations and exocytosis, recent results show that radicals can induce [Ca2+]i oscillations which do not exert exocytosis but inhibit the secretory response to physiological stimuli. Further experiments showed that the [Ca2+]i release caused by radicals originates from thapsigargin-insensitive, ryanodine-sensitive stores. CONCLUSIONS The origin and duration of [Ca2+]i increases rather than their extent or oscillatory nature, determine whether the cell will secrete or die. An abnormal [Ca2+]i increase can trigger trypsin activation, acinar cell damage and acute pancreatitis. This hypothesis is supported by studies which show that calcium chelators inhibit radical-induced trypsin activation as well as cell necrosis and apoptosis. Thus, an inhibition of pathological [Ca2+]i release may have a therapeutic potential.

Abstract
Mononuclear cell (MNC) infiltration of the salivary and lacrimal glands is a major feature in Sjogren's syndrome (SS) and its animal model, murine autoimmune sialoadenitis (MAS). To investigate factors that influence selective infiltration by MNC of submandibular glands in young and adult MRL/lpr mice with MAS, expression of mRNA encoding the beta-chemokines monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)-1alpha, MIP-1beta and regulated upon activation, normal T-cell expressed and secreted (RANTES) was investigated by in situ hybridization. MCP-1 protein production was also evaluated by immunohistochemistry. Young mice with MAS showed an early up-regulation of mRNA expression for MCP-1, MIP-1beta and RANTES, while MIP-1alpha mRNA expression was not affected. Adult mice with MAS showed a further up-regulation of mRNA expression for MCP-1, MIP-1beta and RANTES, and a remarkably strong up-regulation for MIP-1alpha. Immunohistochemistry revealed that MCP-1 protein production paralleled MCP-1 mRNA expression in both young and adult mice. These observations implicate MCP-1, MIP-1beta and RANTES as potential chemokines in induction of MAS, and MCP-1, MIP-1beta, RANTES and prominently MIP-1alpha in progression and perturbation of MAS.
