Abstract
Atherosclerosis is a chronic disease that thickens the blood vessel walls and narrows the lumen. Venous thrombosis is a blood clot that forms in the body's deep veins or pulmonary arteries. However, the relationship between NDUFB11 and NDUFS3 and atherosclerosis and venous thrombosis is unclear. We employed data files that combined atherosclerosis and chronic stress groups. Subsequently, we conducted differential gene expression analysis (DEGs) and performed weighted gene co-expression network analysis (WGCNA). We constructed and analyzed a protein-protein interaction (PPI) network. Further analyses included functional enrichment analysis, gene set enrichment analysis (GSEA), gene expression heatmaps, immune infiltration analysis, and mRNA analysis. By comparing our findings with the Comparative Toxicogenomics Database (CTD), we identified the most relevant diseases associated with the core genes. Additionally, we utilized TargetScan to screen for miRNAs regulating the central DEGs. To validate our results, we conducted Western Blot experiments at the cellular level. A total of 1747 DEGs were co-identified. According to the Gene Ontology (GO) analysis of differentially expressed genes, they were primarily enriched in mitochondrial gene expression, mitochondrial envelope, organelle membrane, and mitochondrial inner membrane categories. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that the target cells were mainly enriched in metabolic pathways, ribosomes, and histidine metabolism. The intersection of enriched terms from both GO and KEGG analyses showed significant enrichment in mitochondrial gene expression, mitochondrial envelope, organelle inner membrane, ribosomal structural constituents, histidine metabolism, and oxidative phosphorylation. Eight core genes were identified, including NDUFS5, UQCRQ, COX6C, COX7B, ATP5ME, NDUFS3, NDUFA3, and NDUFB11. The gene expression heatmap demonstrated that core genes (NDUFB11 and NDUFS3) were downregulated in atherosclerosis with venous thrombosis samples and upregulated in normal samples. CTD analysis revealed that the core genes NDUFB11 and NDUFS3 were associated with pain, arterial diseases, atherosclerosis, arteritis, venous thrombosis formation, and venous thromboembolism. We added Western Blot basic cell experiment for verification. NDUFB11 and NDUFS3 are downregulated in atherosclerosis and venous thrombosis, associated with poorer prognosis, and may serve as potential biomarkers for both diseases.

Abstract
OBJECTIVE Atherosclerosis is characterized by the formation of fibrofatty plaques in the intima of arteries, resulting in thickening of the vessel wall and narrowing of the lumen. Chronic stress refers to individuals in a state of long-term chronic stress. However, the relationship between NDUFB11 and NDUFS3 and atherosclerosis and chronic stress is unclear. METHOD The atherosclerosis with chronic stress group data file was used. DEGs were screened and WGCNA was performed. Construction and analysis of PPI Network. Functional enrichment analysis, GSEA, gene expression heatmap, immune infiltration analysis and mRNA analysis were performed. CTD was used to find diseases most related to core genes. WB was performed. TargetScan was used to screen miRNAs of DEGs. RESULTS 1708 DEGs were identified. According to GO analysis, they were mainly enriched in catabolic processes, organic acid metabolism processes, carboxylic acid metabolism processes. KEGG analysis showed that they were mainly enriched in metabolic pathways, fatty acid metabolism, pentose phosphate pathway, glycolysis / gluconeogenesis, fructose and mannose metabolism. Gene expression heatmap showed that the core genes (NDUFB11, NDUFS3) were lowly expressed in samples of those with atherosclerosis accompanied by chronic stress and highly expressed in the normal samples. NDUFB11 and NDUFS3 were associated with necrosis, hyperplasia, inflammation, renal disease, weight loss, memory impairment, and cognitive impairment. WB showed that the expression level of NDUFS3 in atherosclerosis and chronic stress was lower than that in control group. CONCLUSIONS NDUFB11 and NDUFS3 are underexpressed in atherosclerosis and chronic stress; the lower NDUFB11 and NDUFS3 levels, the worse the prognosis.

Abstract
BACKGROUND Circular RNAs (circRNAs) have attracted extensive attention as therapeutic targets in gastric cancer (GC). Circ_0003356 is known to be downregulated in GC tissues, but its cellular function and mechanisms remain undefined.
AIM To investigate the role of circ_0003356 in GC at the molecular and cellular level.
METHODS Circ_0003356, miR-668-3p, and SOCS3 expression were assessed via quantitative real time-polymerase chain reaction (qRT-PCR). Wound healing, EdU, CCK-8, flow cytometry and transwell assays were used to analyze the migration, proliferation, viability, apoptosis and invasion of GC cells. The subcellular localization of circ_0003356 was monitored using fluorescence in situ hybridization. The interaction of circ_0003356 with miR-668-3p was confirmed using RIP-qRT-PCR, RNA pull-down, and dual luciferase reporter assays. We observed protein levels of genes via western blot. We injected AGS cells into the upper back of mice and performed immunohistochemistry staining for examining E-cadherin, N-cadherin, Ki67, and SOCS3 expressions. TUNEL staining was performed for the assessment of apoptosis in mouse tumor tissues.
RESULTS Circ_0003356 and SOCS3 expression was downregulated in GC cells, whilst miR-668-3p was upregulated. Exogenous circ_0003356 expression and miR-668-3p silencing suppressed the migration, viability, proliferation, epithelial to mesenchy-mal transition (EMT) and invasion of GC cells and enhanced apoptosis. Circ_0003356 overexpression impaired tumor growth in xenograft mice. Targeting of miR-668-3p by circ_0003356 was confirmed through binding assays and SOCS3 was identified as a downstream target of miR-668-3p. The impacts of circ_0003356 on cell proliferation, apoptosis, migration, invasion and EMT were reversed by miR-668-3p up-regulation or SOCS3 down-regulation in GC cells.
CONCLUSION Circ_0003356 impaired GC development through its interaction with the miR-668-3p/SOCS3 axis.

Abstract
The decreased capacity of auxin-, CTK-, and BR-mediated cell division and cell enlargement pathways, combined with the enhanced capacity of GA and ETH-, JA-, ABA-, SA-mediated stress-resistant pathways were presumed to be the crucial reasons for the formation of spur-type 'Red Delicious' mutants. Vallee Spur', which exhibit short internodes and compact tree shape, is the fourth generation of the spur-type bud sport mutant of 'Red Delicious'. However, the underlying molecular mechanism of these properties remains unclear. Here, comparative phenotypic, full-length transcriptome and phytohormone analyses were performed between 'Red Delicious' (NSP) and 'Vallee Spur' (SP). The new shoot internode length of NSP was ˃ 1.53-fold higher than that of the SP mutant. Cytological analysis showed that the stem cells of the SP mutant were smaller and more tightly arranged relative to the NSP. By Iso-Seq, a total of 1426 differentially expressed genes (DEGs) were detected, including 808 upregulated and 618 downregulated genes in new shoot apex with 2 leaves of the SP mutant. Gene expressions involved in auxin, cytokinin (CTK), and brassinosteroid (BR) signal transduction were mostly downregulated in the SP mutant, whereas those involved in gibberellin (GA), ethylene (ETH), jasmonate (JA), ABA, and salicylic acid (SA) signal transduction were mostly upregulated. The overall thermogram analysis of hormone levels in the shoot apex carrying two leaves detected by LC-MS/MS absolute quantification showed that the levels of IAA-Asp, IAA, iP7G, OPDA, and 6-deoxyCS were significantly upregulated in the SP mutant, while the remaining 28 hormones were significantly downregulated. It is speculated that the decreased capacity of auxin, CTK, and BR-mediated cell division and cell enlargement pathways is crucial for the formation of the SP mutant. GA and stress-resistant pathways of ETH, JA, ABA, and SA also play vital roles in stem elongation. These results highlight the involvement of phytohormones in the formation of stem elongation occurring in 'Red Delicious' spur-type bud sport mutants and provide information for exploring its biological mechanism.

Abstract
Background Liriodendrin is a therapeutic constituent of sargentgloryvine stem which is a famous Chinese traditional medicine. Previous studies have suggested liriodendrin could inhibit different pathways to treat inflammation in lung and intestinal tract. But whether it can treat myocardial infarction (MI) is unknown. We investigated the protective effect of liriodendrin on acute MI in rats and explored the specific mechanisms to expand the use of this traditional Chinese medicine. Methods The rats were randomized into the sham group (sham operation), control group (ligation of the left anterior descending artery), and liriodendrin group. The liriodendrin group was intragastrically administered with a liriodendrin solution (100 mg/kg). The control group and the sham group were intragastrically administered with normal saline. Before all rats were euthanized, echocardiography was used to detect their cardiac function. Hematoxylin and eosin (HE) staining and the terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) method were performed. Further quantitative detection of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels in tissues were also detected. Western Blot and real-time polymerase chain reaction (RT-PCR) were used to detect the apoptosis and nuclear factor kappa-B (NF-κB) pathway in tissues. H9C2 cells were used to detect the related mechanisms in vitro. Results Echocardiography showed that, compared to control group, the cardiac function of the liriodendrin group was significantly improved. histopathological staining of the control group showed that the myocardial tissue was severely damaged, and inflammatory cells were infiltrated. Compared to the control group, the apoptosis index of the liriodendrin group was significantly lower (P<0.05). Enzyme-linked immunosorbent assay (ELISA) results showed that the levels of IL-1β and TNF-α in the control group were higher than those in the liriodendrin group (P<0.05). Meanwhile, apoptosis and the NF-κB pathway were inhibited after liriodendrin administration (P<0.05). Moreover, the mRNA transcriptional activity in the control group was also higher than that in the liriodendrin group (P<0.05). Because of the effect of liriodendrin, NF-κB pathway and apoptosis were downregulated in H9C2 cells which were exposed to ischemia-hypoxia. Conclusions Liriodendrin may protect myocardial cells after myocardial infarction in rats by inhibiting the release of inflammatory factors, activation of the NF-κB pathway, and apoptosis.

Abstract
Background To investigate the protective effect of resolvin D1 (RvD1) on aortic dissection (AD) in mice and explore the related mechanisms. Methods Mice were randomly divided into a blank group, model group, and RvD1 group. The RvD1 and model groups were administered 0.4% β-aminopropionitrile (BAPN) solution, while the blank group was administered distilled water. When the experiment began, whether mice had AD was determined by echocardiogram. The RvD1 group was also administered RvD1 (30 µg/kg), while the model and blank groups were administered saline intraperitoneally. After 21 d, body weight trend and survival rate in the three groups were compared. The diameter of the ascending aorta of mice was detected by echocardiography. Then, the mice were sacrificed, and histopathological staining procedures were performed. Enzyme-linked immunosorbent assay (ELISA) was used to detect cytokines and chemokines in blood and tissue, respectively. Results At 21 d, there was no statistically significant difference in body weight between three groups (P>0.05). The survival rate showed a significant difference between the RvD1 and model group (P<0.05). Echocardiography revealed that compared with the RvD1 and blank groups, aortic dilatation was significant in the model group. Pathological staining showed that the destruction of the aortic wall structure and inflammatory cell infiltration were more noticeable in the model group than in the RvD1 group. A slight disintegration of elastic fibers and collagen in the aorta was observed in the RvD1 group, and the aortic structure was clear. The results of ELISA showed that the inflammatory factors levels in the RvD1 group, although higher than those in blank group, were significantly decreased compared with the model group. The ELISA results of AD tissue showed that at 21 d, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels in the aorta were significantly decreased in the RvD1 group compared with the model group (P<0.05). Conclusions Administration of RvD1 significantly delayed aortic dilation and disintegration and inhibited local macrophage and neutrophil infiltration in the early stages of aortic injury. Moreover, RvD1 significantly downregulated the expression of cytokines and chemokines in aortic tissues and serum and improved aortic remodeling.

Abstract
BACKGROUND Stanford type A aortic dissection (TAAD) has a sudden onset and high mortality, and emergency total aortic arch replacement (TAAR) is the main treatment option for TAAD. The mortality rate of patients with postoperative acute kidney injury (AKI) combined with continuous renal replacement therapy (CRRT) is remarkable higher than that of patients without AKI. However, incidence of AKI and risk factors for CRRT following TAAR isn't entirely understood. METHODS From October 2018 to March 2021, all patients with Stanford type A dissection who underwent total arch replacement surgery under MHCA were enrolled. According to whether CRRT treatment was performed, participants were divided into a CRRT group (n=49) and control group (n=72). Both groups incorporated the brain protection strategy of moderate hypothermia, and the left common carotid artery and the innominate artery were perfused anteriorly. Relevant medical data was collected. RESULTS Age, gender, and a history of smoking and drinking were not significantly different between the 2 groups (P>0.1). There were statistical differences between the 2 groups in aortic sinus diameter and Bentall procedure (P≤0.05). Univariate analysis revealed that fresh frozen plasma was a protective factor (P<0.05) and the intraoperative transfusion volume of red blood cells, platelets, fresh frozen plasma, autologous blood used for intraoperative bleeding, aortic sinus diameter, and Bentall procedure were risk factors (P<0.1). Multivariate analysis showed that the Bentall procedure and intraoperative bleeding were risk factors for CRRT (P<0.05), and the aortic sinus diameter and intraoperative transfusion score were also risk factors for CRRT (P<0.05). Receiver operating characteristic (ROC) analysis demonstrated that the model of aortic sinus diameter and intraoperative transfusion score had more significantly different discriminatory powers. CONCLUSIONS The Bentall procedure, intraoperative bleeding, aortic sinus diameter, and intraoperative transfusion score were risk factors for postoperative CRRT. The model of aortic sinus diameter and intraoperative transfusion score had more significantly different discriminatory powers.

Abstract
Background Vein graft restenosis (VGR), which appears to be caused by dyslipidemia
following vascular transplantation, seriously affects the prognosis and
long-term quality of life of patients. Methods This study analyzed the genetic data of restenosis (VGR group) and
non-stenosis (control group) vessels from patients with coronary heart
disease post-vascular transplantation and identified hub genes that might be
responsible for its occurrence. GSE110398 was downloaded from the Gene
Expression Omnibus database. A repeatability test for the GSE110398 dataset
was performed using R language. This included the identification of
differentially expressed genes (DEGs), enrichment analysis via Metascape
software, pathway enrichment analysis, and construction of a protein–protein
interaction network and a hub gene network. Results Twenty-four DEGs were identified between VGR and control groups. The four
most important hub genes (KIR6.1, PCLP1,
EDNRB, and BPI) were identified, and
Pearson’s correlation coefficient showed that KIR6.1 and
BPI were significantly correlated with VGR.
KIR6.1 could also sensitively predict VGR
(0.9 < area under the curve ≤1). Conclusion BPI and KIR6.1 were differentially
expressed in vessels with and without stenosis after vascular
transplantation, suggesting that these genes or their encoded proteins may
be involved in the occurrence of VGR.

Abstract
BACKGROUND Type I diabetes (T1D) is characterized by insulin loss caused by inflammatory cells that excessively infiltrate and destroy the pancreas, resulting in dysregulation of tissue homeostasis, mechanobiological properties, and the immune response. The streptozotocin (STZ)-induced mouse model exhibits multiple features of human T1D and enables mechanistic analysis of disease progression. However, the relationship between the mechanochemical signaling regulation of STZ-induced T1D and macrophage migration and phagocytosis is unclear.
AIM To study the mechanochemical regulation of STZ-induced macrophage response on pancreatic beta islet cells to gain a clearer understanding of T1D.
METHODS We performed experiments using different methods. We stimulated isolated pancreatic beta islet cells with STZ and then tested the macrophage migration and phagocytosis.
RESULTS In this study, we discovered that the integrin-associated surface factor CD47 played a critical role in immune defense in the STZ-induced T1D model by preventing pancreatic beta islet inflammation. In comparison with healthy mice, STZ-treated mice showed decreased levels of CD47 on islet cells and reduced interaction of CD47 with signal regulatory protein α (SIRPα), which negatively regulates macrophage-mediated phagocytosis. This resulted in weakened islet cell immune defense and promoted macrophage migration and phagocytosis of target inflammatory cells. Moreover, lipopolysaccharide-activated human acute monocytic leukemia THP-1 cells also exhibited enhanced phagocytosis in the STZ-treated islets, and the aggressive attack of the inflammatory islets correlated with impaired CD47-SIRPα interactions. In addition, CD47 overexpression rescued the pre-labeled targeted cells.
CONCLUSION This study indicates that CD47 deficiency promotes the migration and phagocytosis of macrophages and provides mechanistic insights into T1D by associating the interactions between membrane structures and inflammatory disease progression.

Abstract
Background Aortic stenosis is a common heart valvular disease whose pathological processes include an inflammatory reaction and lipid accumulation. However, its detailed pathogenesis is yet to be completely elucidated. Therefore, it is of great significance to further explore the molecular mechanisms of aortic stenosis. Methods Four datasets were downloaded from the Gene Expression Omnibus (GEO) database. Firstly, the differently expressed genes (DEGs) were screened between control and aortic stenosis samples. Secondly, weighted gene co-expression network analysis (WGCNA) was performed to find the highly relevant gene modules. Enrichment analysis and protein-protein interaction (PPI) networking were also performed, then Cytoscape was used to identify hub genes. Finally, the six participants (3 control participants and 3 patients with aortic stenosis) were recruited at the Tianjin Chest Hospital. In order to verify the expression level of USP14, several molecular experiments were performed, including hematoxylin-eosin (HE) staining, immunohistochemistry, immunofluorescence technology, real time-quantitative polymerase chain reaction (RT-qPCR), and western blotting. Results A total of 9636 DEGs were found between the control and aortic stenosis samples. The DEGs were mainly enriched in the autophagy-animal, cellular lipid catabolic process, apoptosis, and glycoside metabolic process categories. Eleven hub genes were identified via four different algorithms. Following verification of the patient samples, Ubiquitin-specific protease 14 (USP14) was found to be displayed at higher levels in the aortic stenosis samples. Conclusion USP14 might be involved in the occurrence and development of aortic stenosis, so it would be a molecular target for early diagnosis and specific treatment of aortic stenosis. There is a significant association between the high expression of USP14 and aortic stenosis, indicating that this gene may be a genetic risk factor for aortic stenosis.

Abstract
DNA methylation of anthocyanin biosynthesis-related genes and MYB/bHLH transcription factors was associated with apple fruit skin color revealed by whole-genome bisulfite sequencing. DNA methylation is a common feature of epigenetic regulation and is associated with various biological processes. Anthocyanins are among the secondary metabolites that contribute to fruit colour, which is a key appearance and nutrition quality attribute of apple fruit. Although few studies reported that DNA methylation in the promoter of MYB transcription factor was associated with fruit skin color, there is a general lack of understanding of the dynamics of global and genic DNA methylation in apple fruit. Here, whole-genome bisulfite sequencing was carried out in fruit skin of apple (Malus domestica Borkh.) cv. 'Red Delicious' (G0) and its four-generation bud sport mutants, including 'Starking Red' (G1), 'Starkrimson' (G2), 'Campbell Redchief' (G3) and 'Vallee spur' (G4) at color break stage. Correlation and linear-regression analysis between DNA methylation level and anthocyanin content, as well as the transcription levels of genes related to anthocyanin biosynthesis were carried out. The results showed that the number of differentially methylated regions (DMRs) and differentially methylated genes (DMGs) was considerably increased from G1 to G4 versus the number observed in G0. The mCHH context was dominant in apple, but the levels of mCG and mCHG of DMGs were significantly higher than that of the mCHH. Genetic variation of bud sport mutants from 'Red Delicious' was associated with differential DNA methylation. Additionally, hypomethylation of mCG and mCHG contexts in flavonoid biosynthesis pathway genes (PAL, 4CL, CYP98A, PER, CCoAOMT, CHS, and F3'H), mCHG context in MYB10 at upstream, led to transcriptional activation and was conductive to anthocyanin accumulation. However, hypermethylation of mCG context in bHLH74 at upstream led to transcriptional inhibition, inhibiting anthocyanin accumulation.

Abstract
Chronic stress refers to the non-specific systemic reaction that occurs when the body is stimulated by various internal and external negative factors over a long time. The physiological response to chronic stress exposure has long been recognized as a potent modulator in the occurrence of atherosclerosis. Furthermore, research has confirmed the correlation between atherosclerosis and cardiovascular events. Chronic stress is pervasive during negative life events and may lead to the formation of plaque. Several epidemiological studies have shown that chronic stress is an independent risk factor for the development of vascular disease and for increased morbidity and mortality in patients with pre-existing coronary artery disease. One possible mechanism for this process is that chronic stress causes endothelial injury, directly activating macrophages, promoting foam cell formation and generating the formation of atherosclerotic plaque. This mechanism involves numerous variables, including inflammation, signal pathways, lipid metabolism and endothelial function. The mechanism of chronic stress in atherosclerosis should be further investigated to provide a theoretical basis for efforts to eliminate the effect of chronic stress on the cardiocerebral vascular system.

Abstract
BACKGROUND Bud sport mutants of apple (Malus domestica Borkh.) trees with a highly blushed colouring pattern are mainly caused by the accumulation of anthocyanins in the fruit skin. Hormones are important factors modulating anthocyanin accumulation. However, a good understanding of the interplay between hormones and anthocyanin synthesis in apples, especially in mutants at the molecular level, remains elusive. Here, physiological and comparative transcriptome approaches were used to reveal the molecular basis of color pigmentation in the skin of 'Red Delicious' (G0) and its mutants, including 'Starking Red' (G1), 'Starkrimson' (G2), 'Campbell Redchief' (G3) and 'Vallee spur' (G4). RESULTS Pigmentation in the skin gradually proliferated from G0 to G4. The anthocyanin content was higher in the mutants than in 'Red Delicious'. The activation of early phenylpropanoid biosynthesis genes, including ASP3, PAL, 4CL, PER, CHS, CYP98A and F3'H, was more responsible for anthocyanin accumulation in mutants at the color break stage. In addition, IAA and ABA had a positive regulatory effect on the synthesis of anthocyanins, while GA had the reverse effect. The down-regulation of AACT1, HMGS, HMGR, MVK, MVD2, IDI1 and FPPS2 involved in terpenoid biosynthesis influences anthocyanin accumulation by positively regulating transcripts of AUX1 and SAUR that contribute to the synthesis of IAA, GID2 to GA, PP2C and SnRK2 to ABA. Furthermore, MYB and bHLH members, which are highly correlated (r=0.882-0.980) with anthocyanin content, modulated anthocyanin accumulation by regulating the transcription of structural genes, including CHS and F3'H, involved in the flavonoid biosynthesis pathway. CONCLUSIONS The present comprehensive transcriptome analyses contribute to the understanding of the the relationship between hormones and anthocyanin synthesis as well as the molecular mechanism involved in apple skin pigmentation.

Abstract
OBJECTIVE To study the association of red blood cell distribution width (RDW) and lipoprotein-associated phospholipase A2 (LP-PLA2) with the degree of coronary artery stenosis in patients with coronary artery disease (CAD) and the value of RDW combined with LP-PLA2 detection in accurate evaluation of coronary artery stenosis. METHODS A total of 224 patients including 119 non-CAD cases and 105 CAD cases admitted in our hospital between June, 2013 and June, 2014 were enrolled in this study. The patients' baseline clinical data were collected and venous blood samples were obtained for detecting WBC, RDW-CV and LP-PLA2. The Gensini score of the CAD patients was calculated based on coronary angiographic findings. RESULTS Compared with the non-CAD patients, CAD patients had significantly higher RDW-CV (P=0.009) and LP-PLA2 (P=0.004) levels. The CAD patients with high Gensini scores had also significantly higher RDW-CV (P=0.001) and LP-PLA2 (P<0.001) levels than those with low scores; RDW-CV and LP-PLA2 were significantly correlated with the Gensini score, and the area under curve of their combined detection was 0.931. CONCLUSION Combination of RDW and LP-PLA2 can improve the diagnostic accuracy of the degree of coronary artery stenosis in patients with CAD.

A rat model of chronic alcoholism was used in the study. The spatial learning ability and memory of the rats were tested. The rats were then sacrificed and their brains and hepatic tissues were isolated. The activity of superoxide dismutase (SOD) and levels of glutamate (Glu), N-methyl D-aspartate receptor subtype 2B (NR2B), cyclin-dependent kinase 5 (CDK5) and cannabinoid receptor 1 (CB1) in the hippocampus were analyzed. The ultrastructure of the hepatic tissue was observed by electron microscopy. In addition, the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in serum were tested and the levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG) and total cholesterol (TCHOL) were analyzed. XNJ enhanced the learning and memory of rats with chronic alcoholism. Treatment with XNJ increased the activity of SOD, and decreased the expression levels of NR2B mRNA and NR2B, CB1 and CDK5 proteins in the brain tissues compared with those in the model rats. It also increased the activity of ALDH in the serum and liver, decreased the serum levels of LDL, TG and TCHOL and increased the serum level of HDL. These results indicate that XNJ exhibited a protective effect against brain and liver damage in rats with chronic alcoholism.

Abstract
This study evaluated the feasibility and effectiveness of using the bispectral index (BIS) to monitor anesthetic depth in patients with severe burns receiving intravenous target-controlled infusion (TCI) of remifentanil and propofol. We randomly assigned 80 patients undergoing elective escharectomy (<1 week) to BIS (A) and control (B) groups. All patients received remifentanil and propofol as intravenous TCI anesthesia. Clinical data were recorded at different time points. The time from drug withdrawal to eye opening upon the patient hearing his/her name called and upon reaching an Aldrete score of 9 points was also recorded. During anesthesia maintenance, the target concentrations of remifentanil and propofol in group A were significantly lower than that in group B (2.12 ± 0.35 vs 2.50 ± 0.21 ng/mL and 2.54 ± 0.22 vs 2.86 ± 0.31 μg/mL, respectively; P < 0.01). The time from drug withdrawal to eye opening upon the patient hearing his/her name called and reaching an Aldrete score of 9 points in group A was considerably shorter than that in group B (7.90 ± 0.58 vs 8.35 ± 0.66 min and 9.15 ± 0.69 vs 11.13 ± 0.96 min, respectively; P < 0.01). In both groups, mean arterial pressure and heart rate values at each time point after loss of consciousness were significantly lower than the baseline values (P < 0.05), with the exception of 2 min after intubation. The use of BIS to monitor anesthetic depth in patients with severe burns receiving TCI of remifentanil and propofol during the perioperative period reduces propofol consumption and shortens the consciousness recovery time in patients.

Abstract
We investigated the therapeutic effect of Xin Mai Jia (XMJ) on atherosclerosis (AS) in rats. Rat models of AS were established by peritoneally injecting vitamin D, feeding a high-fat diet, and inducing balloon injuries in rats. The stomachs of the rats were irrigated continuously for 10 weeks with XMJ. Blood lipid- and hemorheology-related indices of blood samples were detected. Pathological changes in the right common carotid arterial tissues were also determined. The protein expression levels of endothelial nitric oxide synthase, angio-tensin-1, and endothelin-1 were determined by western blotting. XMJ reduced cholesterol, trigylecride, and low-density lipoprotein levels as well as blood viscosity, sedimentation, and hematocrit. Furthermore, XMJ alleviated vascular endothelial injury and reduced/eliminated atherosclerotic plaques. In contrast, XMJ significantly increased the endothelium-dependent relaxing response of the AS rat models. The western blotting results showed that XMJ upregulated endothelial nitric oxide synthase but downregulated angiotensin-1 and endothelin-1. XMJ prevented the development of AS by regulating blood lipid levels, hemorheology, and vascular function.

Abstract
Systemic inflammatory response syndrome (SIRS) complicated with ST-elevation myocardial infarction has rarely been reported, and the precise mechanisms of myocardial injury remain unclear. Here, we present a case involving a 45-year-old man who developed SIRS secondary to diabetes-induced infection, and who ultimately developed ST-elevation myocardial infarction with acute heart failure, fulminant diabetes, acute liver dysfunction, acute kidney dysfunction and rhabdomyolysis. The patient eventually recovered due to early detection, correct diagnosis and powerful treatment. Clinicians should be aware of this new type of myocardial infarction, which is induced by inflammatory injury, but is not due to a primary coronary event such as plaque erosion and/or rupture, fissuring or dissection.

Abstract
Rosiglitazone has been found to have anti-atherogenic effects and to increase serum high-density lipoprotein (HDL) cholesterol (HDL-C) levels. However, in vivo studies investigating the regulation of adenosine triphosphate-binding cassette transporter A1 (ABCA1) and scavenger receptor class B type I (SR-BI) by rosiglitazone are limited. Moreover, the effects of rosiglitazone on the function and levels of HDL are unclear. In the present study, we investigated the effects of rosiglitazone on HDL function and its mechanisms of action in atherosclerotic rabbits. Our results revealed that rosiglitazone induced a significant increase in serum HDL-C levels, paraoxonase 1 (PON1) activity, [3H]cholesterol efflux rates, and the expression of ABCA1 and SR-BI in hepatocytes and peritoneal macrophages. The expression of ABCA1 was also increased in aortic lesions. Rosiglitazone markedly reduced serum myeloperoxidase (MPO) activity, aortic intima-media thickness (IMT) and the percentage of plaque area in the aorta. It can thus be concluded that in atherosclerotic rabbits, rosigitazone increases the levels of HDL-C and hinders atherosclerosis. Thus, it improves HDL quality and function, as well as the HDL-induced cholesterol efflux, exerting anti-inflammatory and antioxidant effects.

Abstract
OBJECTIVES This study examined alterations in the functions and proteome of high-density lipoprotein (HDL) subfractions (HDL2 and HDL3) isolated from patients with acute coronary syndrome (ACS) compared with control subjects. METHODS We measured HDL subfraction cholesterol efflux capacity, inflammatory index (HII), paraoxonase-1 (PON1) activity, and lipid hydroperoxide (LOOH) levels in both male age-matched controls and the ACS group (n = 40/group). Additionally, proteomic analysis was used to monitor changes in the HDL subfraction proteome between controls and ACS subjects. RESULTS Both HDL2 and HDL3 from ACS patients had greater HII and LOOH levels compared with controls (P<0.001); PON1 activity and cholesterol efflux capacity in both HDL2 and HDL3 from the ACS group were significantly less than those of controls (P<0.001). Using proteomic analysis, we demonstrated that, compared with the control group, nine proteins were selectively enriched in HDL3 from subjects with ACS, and ras-related protein Rab-7b was decreased in HDL3. Additionally, in the ACS subjects, 12 proteins were decreased in HDL2 and 4 proteins were increased in HDL2. CONCLUSIONS Functional HDL subfractions shifted to dysfunctional HDL subfractions during ACS, and the functional impairment was linked to remodeled protein cargo in HDL subfractions from ACS patients.

Abstract
Background Both L-4F, one apolipoprotein A-1 mimetic peptide, and statins can reduce progression of atherosclerosis by different mechanisms. The combination of the two drugs can cause lesion regression by rendering HDL anti-inflammatory. We postulated that combination of L-4F and simvastatin may stimulate cholesterol efflux and related proteins expressions to alleviate atherosclerosis. Methods Thirty male wild-type (W-T) C57 BL/6 mice and apo E−/− mice were divided into five groups: W-T group, atherosclerosis (AS) group, simvastatin group, L-4F group and the combination of simvastatin and L-4F group. After 16 weeks, serum lipids, atherosclerotic lesion areas, cholesterol efflux and the expressions of related proteins including ABCA1, SR-BI, ABCG1, LXRα and PPARγ were evaluated. Results The aortic atherosclerotic lesion areas were reduced more significantly by combination of both drugs than single agent, and cholesterol efflux was promoted more in combination group than simvastatin and L-4F group. Besides, the combination group promoted expressions of cholesterol efflux related proteins. Conclusions The combination of L-4F and simvastatin reduced atherosclerotic lesions, which stimulates cholesterol efflux by promoting the expressions of related proteins. In addition, these results help us further understand that the regression of the atherosclerosis would be assessed by reduction in LDL-C with increase of cholesterol efflux.

Abstract
AIM: To investigate the effect of laparoscopic Roux-en-Y gastric bypass (LRYGB) on glucose metabolism in obese patients with type 2 diabetes mellitus.
METHODS: Twenty obese patients with type 2 diabetes mellitus underwent LRYGB. Fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 h PBG), C peptide (C-P), glycosylated hemoglobin (HbA1C) and fasting insulin (Fins) were recorded before surgery and at the 1st, 4th, 8th, 12th, and 24th week after surgery. Insulin resistance index (HOMA-IR) was calculated and compared.
RESULTS: LRYGB was successful in all the patients, without intraoperative complications or conversion to open surgery. FBG decreased from 11.25 mmol/L ± 3.36 mmol/L before surgery to 6.21 mmol/L ± 0.52 mmol/L at the 24th week after surgery (P < 0.05), 2 h PBG from 15.33 mmol/L ± 2.54 mmol/L to 8.78 mmol/L ± 1.51 mmol/L (P < 0.05), HbA1C from 9.05% ± 1.27% to 6.53% ± 0.58% (P < 0.05), HOMA-IR from 7.16 ± 0.65 to 3.84 ± 0.47 (P < 0.05), and Fins increased from 11.24 mU/L ± 0.98 mU/L to 12.03 mU/L ± 0.75 mU/L (P > 0.05). The total effective rate was 100%, the recovery rate was 85%, and the improvement rate was 15%.
CONCLUSION: LRYGB can significantly reduce plasma glucose levels and improve glucose metabolism in obese patients with type 2 diabetes mellitus.

Abstract
Concentrations of black carbon (BC) were determined in the surface sediments from the inner continental shelf of the East China Sea (ECS). For comparison, the total organic carbon (TOC) contents, grain size distribution, concentrations of PAHs and DDTs in the sediments were also measured. Total concentration of BC ranged from 0.21 mg x g(-1) to 0.88 mg x g(-1), with the highest level in the depositional center of Yangtze-derived fine particles. Correlation was found to be insignificant between BC and TOC in the surface sediments, suggesting that they possibly came from different sources. The sediment particles showed significant spatial variations, whereas no significant spatial difference was found in BC content, indicating that the deposition process of BC was not controlled by particle size separation. In addition, a poor correlation between BC and PAHs or DDTs was reported in the estuarine-coastal sediments, probably due to the complicated hydrodynamic process and the heterogeneous sources of PAHs and DDTs.

Abstract
Genome-wide association studies have identified susceptibility loci for esophageal squamous cell carcinoma (ESCC). We conducted a meta-analysis of all single-nucleotide polymorphisms (SNPs) that showed nominally significant P-values in two previously published genome-wide scans that included a total of 2961 ESCC cases and 3400 controls. The meta-analysis revealed five SNPs at 2q33 with P< 5 × 10(-8), and the strongest signal was rs13016963, with a combined odds ratio (95% confidence interval) of 1.29 (1.19-1.40) and P= 7.63 × 10(-10). An imputation analysis of 4304 SNPs at 2q33 suggested a single association signal, and the strongest imputed SNP associations were similar to those from the genotyped SNPs. We conducted an ancestral recombination graph analysis with 53 SNPs to identify one or more haplotypes that harbor the variants directly responsible for the detected association signal. This showed that the five SNPs exist in a single haplotype along with 45 imputed SNPs in strong linkage disequilibrium, and the strongest candidate was rs10201587, one of the genotyped SNPs. Our meta-analysis found genome-wide significant SNPs at 2q33 that map to the CASP8/ALS2CR12/TRAK2 gene region. Variants in CASP8 have been extensively studied across a spectrum of cancers with mixed results. The locus we identified appears to be distinct from the widely studied rs3834129 and rs1045485 SNPs in CASP8. Future studies of esophageal and other cancers should focus on comprehensive sequencing of this 2q33 locus and functional analysis of rs13016963 and rs10201587 and other strongly correlated variants.

Abstract
Background Probucol is a unique hypolipidemic agent that decreases high density lipoprotein cholesterol (HDL-C). However, it is not definite that whether probucol hinders the progression of atherosclerosis by improving HDL function. Methods Eighteen New Zealand White rabbits were randomly divided into the control, atherosclerosis and probucol groups. Control group were fed a regular diet; the atherosclerosis group received a high fat diet, and the probucol group received the high fat diet plus probucol. Hepatocytes and peritoneal macrophages were isolated for [3H] labeled cholesterol efflux rates and expression of ABCA1 and SR-B1 at gene and protein levels; venous blood was collected for serum paraoxonase 1, myeloperoxidase activity and lipid analysis. Aorta were prepared for morphologic and immunohistochemical analysis after 12 weeks. Results Compared to the atherosclerosis group, the paraoxonase 1 activity, cholesterol efflux rates, expression of ABCA1 and SR-BI in hepatocytes and peritoneal macrophages, and the level of ABCA1 and SR-BI in aortic lesions were remarkably improved in the probucol group, But the serum HDL cholesterol concentration, myeloperoxidase activity, the IMT and the percentage plaque area of aorta were significantly decreased. Conclusion Probucol alleviated atherosclerosis by improving HDL function. The mechanisms include accelerating the process of reverse cholesterol transport, improving the anti-inflammatory and anti-oxidant functions.

Abstract
Twenty-four surface sediment samples collected in Dahuofang Reservoir were analyzed for organochlorine pesticides (OCPs) and polychlorinated biphenyl(PCBs) residues. The results showed that the recent occurrence levels in sediments were 0.70-3.48 ng x g(-1)(with a mean of 1.58 ng x g(-1) +/- 0.71 ng x g(-1) for HCHs, 0.85-4.94 ng x g(-1) (1.94 ng x g(-1) +/- 0.82 ng x g(-1)) for DDTs, 1.46-3.52 ng x g(-1) (2.42 ng x g(-1) +/- 0.64 ng x g(-1)) for PCBs. The inputs of OCPs and PCBs could be attributed to the recent use of relevant products and the heavy historical application which preserved in agricultural soil in adjacent area. Contamination level of OCPs and PCBs in surface sediments decreased from upstream to downstream, and samples of higher contamination level were located in Hunhe river mouth, both of which indicated distribution of OCPs and PCBs in reservoir was influenced by riverine discharge. The ecological risk assessment suggested that the OCPs in the sediments of the study area might pose a bit high harm to the environment, while PCBs might pose little harm to the environment.

Abstract
OBJECTIVE To analyze the risk factors in the patients over 65 years old undergoing off-pump coronary artery bypass grafting (OPCAG) as grouped by postoperative creatinine clearance rate (Ccr). METHODS A total of 462 consecutive patients over 65 years old undergoing OPCAG from January 2007 to December 2008 were recruited. They were divided into 3 groups by renal functions: normal, minor injury and moderate-severe injury. The risk factors were analyzed by a comparison of postoperative complications, duration of intubation, stay of intensive care unit and mortality rate, et al. RESULTS There was no significant difference between the parameters of preoperative complications, left ventricle ejection fraction (LVEF), left ventricle end diastolic diameter (LVEDD) and lipid level, et al. And the postoperative complications were closely related to the decrease of Ccr and the increases of B-type natriuretic peptide (BNP), CKMB, total bilirubin (TBIL) and LVEDD (P < 0.01 for each). CONCLUSIONS The moderate-severe renal injury (Ccr < 50 ml/min) with the abnormal levels of TBIL, BNP and LVEDD are the risk factors for a worse prognosis in OPCAG patients over 65 years old. Because of the injury of OPCAG, we should pay attention to patients with abnormal renal function (Ccr < 80 ml/min) to prevent an onset of severe complications.

Abstract
We performed a genome-wide association study of esophageal squamous cell carcinoma (ESCC) by genotyping 1,077 individuals with ESCC and 1,733 control subjects of Chinese Han descent. We selected 18 promising SNPs for replication in an additional 7,673 cases of ESCC and 11,013 control subjects of Chinese Han descent and 303 cases of ESCC and 537 control subjects of Chinese Uygur-Kazakh descent. We identified two previously unknown susceptibility loci for ESCC: PLCE1 at 10q23 (P(Han combined for ESCC) = 7.46 x 10(-56), odds ratio (OR) = 1.43; P(Uygur-Kazakh for ESCC) = 5.70 x 10(-4), OR = 1.53) and C20orf54 at 20p13 (P(Han combined for ESCC) = 1.21 x 10(-11), OR = 0.86; P(Uygur-Kazakh for ESCC) = 7.88 x 10(-3), OR = 0.66). We also confirmed association in 2,766 cases of gastric cardia adenocarcinoma cases and the same 11,013 control subjects (PLCE1, P(Han for GCA) = 1.74 x 10(-39), OR = 1.55 and C20orf54, P(Han for GCA) = 3.02 x 10(-3), OR = 0.91). PLCE1 and C20orf54 have important biological implications for both ESCC and GCA. PLCE1 might regulate cell growth, differentiation, apoptosis and angiogenesis. C20orf54 is responsible for transporting riboflavin, and deficiency of riboflavin has been documented as a risk factor for ESCC and GCA.

Abstract
Saruma henryi Oliv. (Aristolochiaceae) is an endangered herb endemic to China. In this study, chloroplast microsatellites (cpSSRs) and sequences of the atpB-rbcL intergenic spacers were employed to reveal its genetic diversity and phylogeographic patterns. We detected high within-species genetic diversity (H(T)=0.939 for cpSSR; H(T)=0.862 for atpB-rbcL) and pronounced among-population genetic differentiation (H(S)=0.182, G(ST)=0.811, R(ST)=0.9, F(ST)=0.93 for cpSSR; H(S)=0.238, G(ST)=0.724, N(ST)=0.758, F(ST)=0.79 for atpB-rbcL) with a strong phylogeographic pattern (R(ST)>G(ST), P<0.01 for cpSSR; N(ST)>G(ST), U=0.25 for atpB-rbcL). Eleven haplotypes were distinguished by cpSSRs and atpB-rbcL intergenic spacers, respectively. The molecular phylogenetic data, together with the geographic distribution of the haplotypes, suggested the existence of multiple localized glacial refugia in Mts. Qinling, eastern Mts. Bashan and the southeastern edge of Yunnan-Guizhou Plateau. Nested clade analysis (NCA) and population genetic analyses supported the limited gene flow (caused by low dispersal capacity and complex topography of its habitats) as the major factor responsible for the strong population differentiation and phylogeographic pattern. Past fragmentation and allopatric fragmentation were inferred as important processes responsible for the modern phylogeograhpic pattern. In addition, contiguous range expansions occurred in western Mts. Qinling and eastern Mts. Bashan.

Abstract
The first-stage storage of the Three Gorges Project started on the 1st June, 2003 and ended on the 10th June, 2003. In order to investigate the influences of the Three Gorges Project on the Changjiang Estuary and adjacent area environment, a cruise was carried out from the 15th June, 2003 to the 25th June, 2003 to synthetically study the environment. Suspended matter concentrations (SMC) in different water layers at different sites were calculated and distributions of SMC were discussed combining with salinity and temperature of water based on recovered data. In results, SMC increase from surface to bottom in Changjiang Estuary and adjacent area. Suspended matters are enriched in the water over the river mouth bar and alongshore area which are located at the west of 123 degrees E. Compared to that before the storage, SMC are reduced obviously in the Changjiang course and south branch after the storage. For example, at the Xuliujing, SMC are reduced from 400 - 500 mg/L to 60.2 mg/L, and in the south branch, from 445 mg/L to 148 mg/L. In other areas, SMC do not show a significant change that they are both less than 10 mg/L in the surface player and 100 mg/L in bottom player. Generally, the distributed patterns of SMC in the investigation area after the storage are still similar to that before the storage.

Abstract
To study the possibility of utilizing genetically engineered Leifsonia xyli subsp. cynodontis (Lxc) as an endophytic bacterium in rice, we constructed an Escherichia coli-Lxc shuttle vector, pLGUS, containing a beta-glucuronidase reporter gene, which was stable both in vitro and in vivo. Lxc grows and expresses the beta-glucuronidase reporter gene in all parts of rice, except for seed. A 2-year field study using three rice varieties from China showed that Lxc inoculation did not have a negative effect on the growth and yield of any of these varieties. Therefore, Lxc has the potential to be used as a benign endophyte for the expression of foreign genes in rice.

Abstract
OBJECTIVE To identify ATP-binding cassette transporter A1 (ABCA1) gene polymorphism in Chinese patients with coronary artery disease (CAD). METHODS Single Nucleotide Polymorphisms in the ABCA1 gene were detected by polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP)-DNA sequence and restriction-fragment length polymorphism (RFLP) method in 112 patients with CAD. RESULTS A novel polymorphism in the ABCA1 gene was found in two patients: M233V which exists in exon7 of ABCA1 gene and it's cDNA location is A1092G and converse 233 amino acid from Methionine to Valeric. We further collected the blood samples from 16 family members of one proband and M233V polymorphism was found in 5 out 16 family members. CONCLUSION M233V is a novel polymorphism in the ATP-binding cassette transporter A1 gene and this AG genotype had family proneness.

Abstract
To date, the hepatic differentiation of embryonic stem (ES) cells into biliary epithelial (BE) cells has only been identified in hepatocytes. In this study, an attempt was made to induce the differentiation of ES cells to BE cells. In order to induce hepatic, and then BE cell differentiation, growth factors such as TGF, FGF, HGF and EGF were added to the culture medium supplied to embryonic bodies (EBs) that were derived from ES cells. The marker genes and corresponding proteins of hepatocytes and BE cells such as AFP, ALB, CK8, CK18, CK7, CK19 and GGT, etc. were detected by reverse transcriptase-polymerase chain reaction (RT-PCR), immunocytochemistry (ICC) and enzymatic histochemistry. Lastly, the ratio of BE-like cells to all EBs cells was analyzed and determined by flow cytometry (FCM). Hepatocyte and BE cell marker genes and proteins were found to be expressed in the cytoplasm of differentiated cells. On day 10 of differentiation, many round structures appeared in the EBs culture system and the marker proteins of BE cells were found to be expressed in these structures. The BE cell differentiation ratio continually increased from its initial value of 1.7% on day 13 to 7.4% on day 21. ES cells were found to be able to differentiate into BE cells when cultured using medium with appropriate cell growth factors. These BE cells may be a novel source of differentiated cell types for liver engineering.

Abstract
In the present study, we perfused the rhesus lung vascular bed in situ with sulfo-NHS-LC-Biotin to biotinylate its luminal surface membrane proteins. After homogenization, dialysis, and affinity chromatography, biotinylated endothelial membrane proteins were successfully isolated and characterized as enriched endothelial membrane proteins with no contamination of intracellular proteins. When they were used as immunogens to develop monoclonal antibodies (MAbs), three MAbs--TX111, TX112, and TX113--were obtained. Among them, TX111 was demonstrated to specifically bind to rhesus lung tissue by Western blotting and enzymelinked immunosorbent assay (ELISA)--that is, positively stained capillary endothelium of rhesus lung. The molecular weight of the corresponding antigen for TX111 was approximately 70 kDa under reducing conditions. TX111 also reacted with human lung homogenate, but not with rat lung homogenate. These results suggest that (1) the biotinylation method is applicable for isolating endothelial proteins in situ from large animals; (2) anti-human protein MAbs are likely to be obtained using monkey proteins; and (3) TX111 is potentially useful for pulmonary vascular targeting.

Abstract
Vascular endothelium has attracted extensive attention due to its important role in many physiological and pathological processes. Many methods have been developed to study the components and their functions in vascular endothelium. Here we report a novel approach to investigate vascular endothelium using normal rat lungs as the model. We perfused lung vascular beds with sulfosuccinimidyl-6-(biotinamido) hexanoate, a biotin analog, to label endothelial membrane proteins. The biotinylated proteins were isolated from lung homogenate with immobilized monomeric avidin and confirmed to be highly pure endothelial membrane proteins with little contamination of intracellular proteins. These biotinylated proteins were used as immunogens for development of monoclonal antibodies. Indeed, newly generated monoclonal antibodies have revealed different expression patterns of proteins across tissues. Some proteins were found highly specifically expressed to capillary vessels of pulmonary vasculature. This method has also been proven useful for investigating vasculature of other organs, as this study explored.

Abstract
OBJECTIVE To determine the contents of berberine in Coptis chinensis of Lichuan and establish its best cultivation scheme. METHOD We used high performance liquid chromatography (HPLC) to measure the contents of berberine at different altitude, growth age, and leaves. RESULTS Analytic data showed that the growth age and firry woods shading did not affect the contents of berberine in rhizome of Coptis chinensis. Low altitude was more suitable for Coptis chinensis to synthesize berberine. The contents of berberine in rhizome of Coptis chinensis with floral leaf were higher than those with lusterless and lustrous leaves, but no significant difference. CONCLUSION The synthesis of berberine is closely correlated with shading conditions. It is recommended that the shading ratio should be reduced or the sheds removed in the middle growth age (2-3 years), and then the herb should be reshaped at the last year to enhance the synthesis of berberine, so as to obtain high-quality Coptis chinensis in the harvest.

Abstract
OBJECTIVE To explore the differential diagnosis of early repolarization syndrome (ERS) in patients with ST-segment elevation and its clinical significance. METHODS Five patients with ESR were clinically observed and followed up after discharge from hospital. RESULTS All the patients complained of chest distress or chest pain, accompanied by ST-segment elevation in the precordial electrocardiogram leads. CONCLUSION ESR is often misdiagnosed as acute myocardial infarction, acute coronary syndrome, Brugada syndrome or other diseases that may involve elevated ST-segment, and careful examination of the ECGs, echocardiogram, troponin I and the patients' history of heart diseases may help differentiate ESR from these diseases.

Abstract
AIM To investigate the pro-apoptotic role of tumor necrosis factor alpha (TNF-alpha) in cultured bovine aortic endothelial cells (BAEC) and its underlied apoptotic signaling pathways. METHODS BAEC were cultured and passaged in Dulbecco's modified Eagle's medium (DMEM). Morphologic changes and quantification of apoptotic cells were determined under fluorescence microscope after TNF-alpha treated BAEC for 24 h with Hoechst 33258 staining. Cell viability was determined with MTT method. DNA fragmentation was visualized by agarose gel electrophoresis. The expression of phospho-p38 and phospho-p44/42 Ca2+-calmodulin dependent protein kinase (CCDPK, formerly called MAPK) was measured by Western blotting. RESULTS TNF-alpha elicited typical apoptotic morphologic changes (chromatic condensation, nucleus fragmentation) and DNA fragmentation. At 1000-5000 kU/L, incubation with TNF-alpha for 24 h induced BAEC apoptosis and both of phospho-p38 and phospho-p44/42 CCDPK expression in a concentration-dependent manner. Interestingly, TNF-alpha-stimulated activation of p44/42 CCDPK was completely blocked, TNF-alpha-induced apoptosis was markedly increased by preincubation with U0126, a specific p44/42 CCDPK inhibitor. However, SB203580, a specific p38 CCDPK inhibitor, completely blocked TNF-alpha-stimulated activation of p38 CCDPK, and enhanced the expression of phospho-p44/42 CCDPK induced by TNF-alpha, substantially inhibited the pro-apoptotic effect of TNF-alpha. CONCLUSION TNF-alpha simultaneously activates p38 CCDPK and p44/42 CCDPK, and these two CCDPK signaling pathways appeared to play opposing roles in TNF-alpha-induced apoptosis in BAEC.
