Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is one of the most lethal malignancies worldwide. Increasing evidence suggests that human papillomavirus (HPV) infection may be associated with the etiology of ESCC. However, the precise role of HPV in ESCC remains unclear. METHODS AND RESULTS Proliferation and apoptosis of ESCC cells upon infection with HPV16 E6 were detected using CCK-8 assays and Western blot analyses. The migration rate was measured with a wound healing assay, and a Transwell Matrigel invasion assay was used to detect the invasive ability. RT-qPCR was performed to detect the expression of E6AP, p53, and miR-34a. The proliferation rates were significantly higher in HPV16E6-transfected cell groups compared with the negative control groups. Bax protein expression was downregulated in HPV16E6-treated groups compared to the controls. The wound healing and Transwell Matrigel invasion assays indicated that HPV16 E6 infection could increase ESCC cell migration and invasion. Furthermore, E6AP, p53 and miR-34a expression were decreased in HPV16 E6-transfected cell lines. CONCLUSION Our results not only provide evidence that HPV16 E6 promotes cell proliferation, migration, and invasion in ESCC, but also suggests a correlation between HPV infection and E6AP, p53 and miR-34a expression. Consequently, HPV16 E6 may play an important role in ESCC development.

Abstract
ObjectiveThe overexpression of polo-like kinase 1 (PLK-1) has been found in a broad spectrum of human tumors, making it an attractive prognostic tumor biomarker. Nowadays, PLK-1 is considered a cancer therapeutic target with clinical therapeutic value. The aim of the present study was to systematically review the prognostic and therapeutic value of PLK-1 in different malignant neoplasms.MethodsA systematic literature search of the Cochrane Library, PubMed, Web of Science, and China National Knowledge Internet (CNKI) databases was conducted between December 2018 and September 2022. In total, 41 published studies were screened, comprising 5,301 patients. We calculated the pooled odds ratios (ORs) and corresponding 95%CIs for the clinical parameters of patients included in these studies, as well as the pooled hazard ratios (HRs) and corresponding 95% CIs for 5-year overall survival (OS).ResultsOur analysis included 41 eligible studies, representing a total of 5,301 patients. The results showed that overexpression of PLK-1 was significantly associated with poor OS (HR, 1.57; 95% CI, 1.18–2.08) and inferior 5-year disease-free survival/relapse-free survival ((HR, 1.89; 95% CI, 1.47–2.44). The pooled analysis showed that PLK-1 overexpression was significantly associated with lymph node metastasis, histological grade, clinical stages (p < 0.001 respectively), and tumor grade (p < 0.001). In digestive system neoplasms, PLK-1 overexpression was significantly associated with histopathological classification, primary tumor grade, histological grade, and clinical stages (p = 0.002, p = 0.001, p < 0.0001, respectively). In breast cancer, PLK-1 was significantly associated with 5-year overall survival, histological grade, and lymph node metastasis (p < 0.001, p = 0.003, p < 0.001, respectively). In the female reproductive system, PLK-1 was significantly associated with clinical stage (p = 0.011). In the respiratory system, PLK-1 was significantly associated with clinical stage (p = 0.021).ConclusionOur analysis indicates that high PLK-1 expression is associated with aggressiveness and poor prognosis in malignant neoplasms. Therefore, PLK-1 may be a clinically valuable target for cancer treatment.

Abstract
Objective: To investigate the association of blood lead and blood selenium with serum high-sensitivity C-reactive protein (hs-CRP) among Chinese adults aged 19 to 79 years. Methods: The participants were enrolled from the first wave of China National Human Biomonitoring (CNHBM) conducted from 2017 to 2018. 10 153 participants aged 19 to 79 years were included in this study. Fasting blood samples were obtained from participants. Lead and selenium in whole blood and hs-CRP in serum were measured. Individuals with hs-CRP levels above 3.0 mg/L were defined as elevated hs-CRP. Generalized linear mixed models and restricted cubic spline models were used to analyze the association of blood lead and blood selenium with elevated hs-CRP. Logistic regression models were used to analyze the multiplicative scale and additive scale interaction between blood lead and blood selenium on elevated hs-CRP. Results: The age of participants was (48.91±15.38) years, of which 5 054 (61.47%) were male. 1 181 (11.29%) participants were defined as elevated hs-CRP. After multivariable adjustment, results from generalized linear models showed that compared with participants with the lowest quartile of blood lead, the OR (95%CI) of elevated hs-CRP for participants with the second, third, and highest quartiles were 1.14 (0.94-1.37), 1.25 (1.04-1.52) and 1.38 (1.13-1.68), respectively. When compared with participants with the lowest quartile of blood selenium, the OR (95%CI) of elevated hs-CRP for participants with the second, third and highest quartiles were 0.86 (0.72-1.04), 0.91 (0.76-1.11), and 0.75 (0.61-0.92), respectively. Results from the interaction analysis showed no significant interaction between lead and selenium on elevated hs-CRP. Conclusion: Blood concentration of lead was positively associated with elevated serum hs-CRP, and blood concentration of selenium was inversely related to elevated hs-CRP, while blood lead and selenium did not present interaction on elevated hs-CRP.

Abstract
OBJECTIVES High-risk human papillomavirus (HR-HPV) is an important risk factor for esophageal cancer. Macrophages constitute a crucial immune medium for regulating HPV-related tumors; however, the specific regulatory mechanisms remain unknown. Therefore, the purpose of our current study was to investigate the mechanism by which HPV16E6 regulates macrophages to promote the invasion and metastasis of esophageal cancer. METHODS HPV16E6 infection was detected by polymerase chain reaction. Immunohistochemistry was used to verify the distribution of tumor-associated macrophages (TAMs) and MMP-9 expression in esophageal squamous cell carcinoma tissues (ESCCs), and cancer adjacent normal tissues (CANs) from Kazakh patients. ESCC cells were transfected with a plasmid over-expressing HPV16E6 and non-contact cocultured with macrophages. RESULTS The infection rate of HPV16E6 in Kazakh ESCCs was clearly higher than that in CANs (P < 0.05). The density of CD163-positive TAMs was significantly positively correlated with HPV16E6 infection in ESCCs (P < 0.05). After coculturing macrophages and EC9706 cells transfected with the HPV16E6 plasmid, the phenotype of macrophages transformed into M2 macrophages. The migration and invasion ability of ESCC cells were higher in the HPV16E6-transfected and coculture group than in the HPV16E6 empty vector-transfected and non-cocultured HPV16E6-transfected groups (all P < 0.05). The density of M2-like TAMs in ESCCs was positively correlated with the level of MMP-9 expression. MMP-9 expression in the HPV16E6-ESCC coculture macrophages group was substantially higher than that in controls (all P < 0.05). CONCLUSIONS HPV16 infection mediates tumor-associated macrophages to promote ESCC invasion and migration.

Abstract
Introduction The methylation at position N6 of adenine is called N6-methyladenosine (m6A). This transcriptional RNA modification exerts a very active and important role in RNA metabolism and in other biological processes. However, the activities of m6A associated with malignant liver hepatocellular carcinoma (LIHC) are unknown and are worthy of study. Materials and Methods Using the data of University of California, Santa Cruz (UCSC), the expression of M6A methylation regulators in pan-cancer was evaluated as a screening approach to identify the association of M6A gene expression and 18 cancer types, with a specific focus on LIHC. LIHC datasets of The Cancer Genome Atlas (TCGA) were used to explore the expression of M6A methylation regulators and their clinical significance. Gene Ontology (GO) analysis and Gene Set Enrichment Analysis (GSEA) were used to explore the underlying mechanism based on the evaluation of aberrant expression of m6A methylation regulators. Results The expression alterations of m6A-related genes varied across cancer types. In LIHC, we found that in univariate Cox regression analysis, up-regulated m6A modification regulators were associated with worse prognosis, except for ZC3H13. Kaplan-Meier survival curve analysis indicated that higher expression of methyltransferase-like protein 3 (METTL3) and YTH N6-methyladenosine RNA binding protein 1 (YTHDF1) genes related to the worse survival rate defined by disease-related survival (DSS), overall survival (OS), progression-free interval (PFI), and disease-free interval (DFI). Up-regulated m6A methylation regulator group (cluster2) obtained by consensus clustering was associated with poor prognosis. A six-gene prognostic signature established using the least absolute shrinkage and selection operator (LASSO) Cox regression algorithm performed better in the early (I + II; T1 + T2) stages than in the late (III + IV; T3 + T4) stages of LIHC. Using the gene signature, we constructed a risk score and found that it was an independent predictive factor for prognosis. Using GSEA, we identified processes involved in DNA damage repair and several biological processes associated with malignant tumors that were closely related to the high-risk group. Conclusion In summary, our study identified several genes associated with m6A in LIHC, especially METTL3 and YTHDF1, and confirmed that a risk signature comprised of m6A-related genes was able to forecast prognosis.

Abstract
Objective To investigate the application value of eye tracking in lie detection. Methods The 40 subjects were randomly divided into two groups. The pupil diameter, fixation duration, points of fixation and blink frequency of the subjects in the experimental group in observing target stimulation and non-target stimulation were recorded with eye tracker after they accomplished the mock crime. The eye movement parameters of subjects in the control group were directly collected. The differences in eye movement parameters of the experimental group and the control group in observing target stimulation and non-target stimulation were analyzed by t-test. Pearson coefficient analysis of correlation between eye movement parameters that had differences was conducted. The effectiveness of eye movement parameters to distinguish between the experimental group and the control group was calculated by the receiver operator characteristic (ROC) curve. Results Participants from the experimental group had shorter average pupil diameter, longer average fixation duration and fewer fixation points (P<0.05), but the differences in blink frequency had no statistical significance. The differences in the above indicators of the control group in observing target stimulation and non-target stimulation had no statistical significance. The average fixation duration showed a negative correlation with fixation points (r=-0.255, P<0.05); the average fixation duration showed a negative correlation with average pupil diameter (r=-0.218, P<0.05); the fixation points showed a positive correlation with average pupil diameter (r=0.09, P<0.05). The area under the curve of average pupil diameter, average fixation duration and fixation points was 0.603, 0.621 and 0.580, respectively. Conclusion The average pupil diameter, average fixation duration and fixation points obtained by the eye tracker under laboratory conditions can be used to detect lies.

Abstract
Strain-coupled magnetoelectric (ME) phenomena in piezoelectric/ferromagnetic thin-film bilayers are a promising paradigm for sensors and information storage devices, where strain manipulates the magnetization of the ferromagnetic film. In-plane magnetization rotation with an electric field across the film thickness has been challenging due to the large reduction of in-plane piezoelectric strain by substrate clamping, and in two-terminal devices, the requirement of anisotropic in-plane strain. Here we show that these limitations can be overcome by designing the piezoelectric strain tensor using the boundary interaction between biased and unbiased piezoelectric. We fabricated 500 nm thick, (001) oriented [Pb(Mg1/3Nb2/3)O3]0.7-[PbTiO3]0.3 (PMN-PT) unclamped piezoelectric membranes with ferromagnetic Ni overlayers. Guided by analytical and numerical continuum elastic calculations, we designed and fabricated two-terminal devices exhibiting electric field-driven Ni magnetization rotation. We develop a method that can apply designed strain patterns to many other materials systems to control properties such as superconductivity, band topology, conductivity, and optical response.

Abstract
BACKGROUND Gallbladder squamous cell carcinoma (GBSCC) is a rare subtype of malignancy and accounts for only 2%-3% of gallbladder malignancies. Due to its rapid development, most patients with GBSCC initially present with an advanced stage of the disease and hence a poor prognosis. The clinicopathological and biological features of SCC remain to be fully elucidated, owing to its uncommon occurrence. The majority of currently available data only described individual case reports or series analyses of trivial cases.
CASE SUMMARY A 64-year-old man was admitted for progressively poor abdominal distension and pain. Liver computed tomography (CT) showed infiltration of gallbladder carcinoma into the adjacent liver, and enlarged retroperitoneal lymph nodes. The patient underwent radical cholecystectomy. Part of the mass was grey and soft, and the neoplastic section showed a purulent-necrotic lesion. Hematoxylin and eosin staining revealed a moderately differentiated SCC. Immunohistochemical studies showed strong staining of the tumor for AE1/3 and CK5/6. Staining for CK19, CK7, and CAM5.2 was positive in the cytoplasm. Systemic chemotherapy was not administered because of the patient’s poor physical condition. After five months, CT and magnetic resonance cholangiopancreatography showed multiple metastases in the liver and abdominal cavity.
CONCLUSION Squamous components of GBSCC may explain the complex biological behavior, and CD109 may be involved in the pathogenesis.

Abstract
BACKGROUND Nonlinear optical microscopic (NLOM) imaging technique shows its high resolution imaging features in histocytology. The purpose of this study was to investigate NLOM imaging technique as a useful tool for a donor kidney quality assessment. MATERIALS AND METHODS Eighty-three pretransplant kidney biopsies from adult donors were analyzed retrospectively. Each specimen was paraffin-embedded and sectioned into 2 consecutive 5-μm thick sections. One section was stained with Masson trichrome, and the other was left unstained for NLOM imaging using second harmonic generation combined with two-photon excited fluorescence (SHG/TPEF). The pretransplant kidney quality was assessed by an experienced pathologist using the Remuzzi scoring system, which characterizes renal tissue morphology into 4 aspects: tubular atrophy, interstitial fibrosis, glomerulosclerosis, and vascular injury. The K coefficient was used to measure the consistency of the Remuzzi scores between conventional Masson trichrome stained images and SHG/TPEF images. RESULTS NLOM imaging technology can capture high-resolution tissue images from unstained renal tissue, is easy to operate, and shortens time-consuming histological processing procedures. No significant differences (P > .05) were found between the Remuzzi scores of the SHG/TPEF images and the Masson trichrome stained images. The high κ coefficients (0.804-0.895) showed a good consistency between these 2 techniques. CONCLUSION The NLOM technique is suitable for renal tissue imaging and could potentially be used for routine pretransplant kidney evaluation in clinical settings.

Abstract
OBJECTIVE To evaluate the value of conventional and age-adjusted D-dimer cut-off value combined with 2-level Wells score for diagnosis of suspected pulmonary embolism. METHODS In the study, 335 patients with suspected pulmonary embolism who visited Peking University People's Hospital were enrolled retrospectively, then 274 patients with age over fifty years were chosen. The 2-level Wells score was applied to evaluate the clinical probability of pulmonary embolism, the diagnostic value of traditional D-dimer cut-off value (500 μg/L) and age adjusted D-dimer cut-off value (age×10 μg/L above 50 years) combined with Wells score no greater than 4 were compared. Computed tomography pulmonary arteriography (CTPA) was considered as the gold standard for diagnosis of pulmonary embolism. RESULTS (1) The area under a receiver operating characteristic (ROC) curve (AUC) in analysis of the combination of Wells score no greater than 4 and traditional D-dimer cut-off value was 0.764 (95%CI: 0.703-0.818). On the other hand, the AUC in a ROC analysis of the combination of Wells Score no greater than 4 and age-adjusted D-dimer cut-off value was 0.814 (95%CI:0.756-0.863). These two results did not differ statistically (Z=0.05, P=0.121). (2) The sensitivity, specificity, positive predictive value, negative predictive value and Youden index of the diagnosis of pulmonary embolism of the combination of traditional D-dimer cut-off value and 2-level Wells Score were 100%, 48.9%, 28.8%, 100%, and 0.49, respectively. Meanwhile, the sensitivity, specificity, positive predictive value, negative predictive value and Youden index of the diagnosis of pulmonary embolism of the combination of age-adjusted D-dimer cut-off value and 2-level Wells Score were 97.4%, 62.3%, 35.5%, 99.1%, and 0.60, respectively. Compared with using traditional D-dimer cut-off value, using age-adjusted D-dimer cut-off value could improve the diagnosis specificity (traditional D-dimer cut-off value group: 48.9%, age-adjusted D-dimer cut-off value group: 62.3%) of pulmonary embolism without reducing the sensitivity (traditional D-dimer cut-off value group: 100%, age-adjusted D-dimer cut-off value group: 99.1%). (3) Among the 222 patients with Wells Score no greater than 4, 90 patients were with D-dimer less than traditional cut-off value (500 μg/L), and 25 patients (account for 11.3% of all 222 patients) were with D-dimer between traditional cut-off value and age-adjusted cut-off value. CONCLUSION The application of age-adjusted D-dimer cut-off value can improve the diagnostic specificity of pulmonary embolism in patients over 50 years, without reducing the sensitivity. It can be used for ruling out suspected pulmonary embolism safely.

Abstract
OBJECTIVE The present study aimed to explore the role and the underlying mechanism of miR-221 in Parkinson's Disease. MATERIALS AND METHODS To perform our investigation, a PD cell model was created by using 6-OHDA. Cell viability and proliferation assays, and flow cytometry analysis were performed to detect cell viability and apoptosis. The qRT-PCR and western blotting were used for gene and protein level detection. RESULTS We found that the expression of miRNA-221 is significantly lower in 6-OHDA treated PC12 pheochromocytoma cells compared to the normal cells. The results of further analysis indicated that miR-221 mimic significantly promoted the cell viability and proliferation of PC12 cells treated with 6-OHDA. MiR-221 mimic significantly inhibited 6-OHDA-treated PC12 cells from apoptosis. These effects were eliminated by PTEN over-expression. We also revealed that PTEN was a direct target gene of miR-221. Moreover, we found miR-221 mimic significantly promoted the phosphorylation of AKT in PC12 cells treated with 6-OHDA, and over-expression of PTEN could eliminate this effect. CONCLUSIONS MiR-221 plays a protective role in Parkinson's Disease via regulating PC12 cell viability and apoptosis by targeting PTEN. Therefore, miR-221 may serve as a potential therapeutic target for Parkinson's disease treatment (Fig. 3, Ref. 27).

Abstract
Synovial sarcoma (SS) is a mesenchymal malignant neoplasm showing characteristics of epithelial-mesenchymal biphasic differentiation. SS is of uncertain cellular origin; however, studies have suggested that SS originates from a somatic stem cell population. In this study, we aim to determine whether differential morphological features of the epithelial-mesenchymal transition (EMT) contributed to the tumourigenesis of SS invasion and metastasis. Twelve paraffin-embedded formalin-fixed tissue (FFPE) SS tissue specimens were obtained, and laser capture microdissection (LCM) with the ArcturusXT system and small chip method (SCM) were used to isolate and purify spindle and epithelial cells from SS specimens. The TRIzol method was used to extract RNA, and the mRNA levels of EMT-related genes in epithelial and spindle cells of SS specimens were measured using real-time fluorescent quantitative reverse transcription polymerase chain reaction (qRT-PCR). The results show that collection of about 2 × 104 cells from FFPE samples using LCM was sufficient for qRT-PCR, with an efficiency of 75%. Compared with LCM, 72.2% (13 of 18) RNA samples were successfully extracted using SCM to isolate cells from FFPE SS tissues. In the 16 samples (11 spindle cell samples and 5 epithelial cell samples), Snail mRNA was significantly upregulated in spindle cell areas compared with that in epithelial cell areas (P = .001). Expression levels of the epithelial marker E-cadherin and the mesenchymal marker N-cadherin were not significantly different between epithelial and spindle cell areas. In spindle cells of recurrent SS samples, the mRNA levels of E-cadherin, N-cadherin, Snail, and Slug were higher in primary SS samples than in recurrent samples. Taken together, our results indicated that in SS samples, Snail mRNA was upregulated in spindle cell areas compared with that in epithelial cell areas and that the expression of EMT-related genes was increased in primary SS. LCM could be used to isolate and purify RNA from FFPE samples.

Abstract
BACKGROUND To find potential serum biomarkers of microwave ablation (MWA) for treatment of human lung cancer by 1H nuclear magnetic resonance (NMR)-based metabolomics analysis. METHODS Serum specimens collected from 43 healthy individuals, 39 patients with advanced non-small cell lung cancer (NSCLC) and 38 NSCLC patients treated with MWA, were subjected to 1H NMR-based metabolomics analysis. Partial least squares discriminant analysis was used to analyze the data. RESULTS Compared with healthy controls, NSCLC patients showed significantly elevated serum levels of lactate, alanine, glutamate, proline, glycoprotein, phenylalanine, tyrosine and tryptophan, and markedly decreased serum levels of glucose, taurine, glutamine, glycine, phosphocreatine and threonine (p < 0.05). MWA treatment reversed the metabolic profiles of NSCLC patients towards the control group. CONCLUSIONS 1H NMR-based metabolomics analysis enhanced the current understanding of the mechanisms involved in NSCLC, and uncovered the therapeutic potential of MWA for treatment of NSCLC. The above disturbed serum metabolites were proposed to be the potential biomarkers that may help to predict NSCLC and to evaluate the efficacy of MWA in the treatment of NSCLC.

Abstract
Multiple chromosome aberrations are responsible for tumorigenesis of esophagus squamous cell carcinoma (ESCC). To characterize genetic alterations by comparative genomic hybridization (CGH) and their relation to ESCC, We enrolled 54 members with ESCC from Kazakh's patients. We found that the deletions of 3p (P = 0.032), 17p (P = 0.004), 22q (P = 0.000) and gains of 5p (P = 0.000), 11q (P = 0.000) were significantly correlated with the location of tumors. Losses of 1p (P = 0.005), 3p (P = 0.006), 22q (P = 0.024) and gains of 3q (P = 0.043), 8q (P = 0.038), 18q (P = 0.046) were also found more frequently in patients with larger diameter disease. The loss of 19q (P = 0.005) and gains of l3q (P = 0.045), 18p (P = 0.018) were significantly correlated with pathologic grade. The gain of 7p (P = 0.009) and deletion of 19q (P = 0.018) were seen more frequently in patients with Grade III-IV tumors. Chromosome amplifications in ESCC at 1q (P = 0.008), 7p (P = 0.008), 8q (P = 0.018) and deletions at 3p (P = 0.021), 11q (P = 0.002), 17p (P = 0.012) were related to lymph node metastasis; the gains of 1q (P = 0.026) and 6q (P = 0.017) and the loss of 11q (P = 0.001) were significant in different isoforms of HPV infection. We identified some chromosomes in which the genes were related to the tumorgenesis of ESCC, which may be a theme for future investigation.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of the frequent malignant tumors with poor prognosis worldwide. Identifying the prognostic biomarkers and potential mechanisms of such tumors has attracted increasing interest in esophageal cancer biology. Our previous study showed that phospholipase C elipson 1 (PLCE1) expression is up-regulated and associated with disease progression in esophageal carcinoma. MicroRNAs (miRNAs) play vital roles in regulating its target gene expression. However, studies on miRNA-regulated PLCE1 expression and its cellular function are still very few. We found that miR-34a is significantly expressed lower in ESCC tissues. We further showed that PLCE1 is a direct functional target gene of miR-34a, and the functional roles of miR-34a in ESCC cell lines in vitro were also determined through gain- and loss-of-function analyses. Results revealed that miR-34a functions as a tumor suppressor by inhibiting the proliferation, migration, and EMT phenotype, as well as promoting apoptosis of ESCC cell lines. Moreover, PLCE1 is overexpressed in ESCC tumors and promotes tumorigenicity in vivo and vitro. PLCE1 expression is negatively correlated with miR-34a profiles in ESCC tissues. Our data suggest that miR-34a exerts its anti-cancer function by suppressing PLCE1. The newly identified miR-34a/PLCE1 axis partially illustrates the molecular mechanism of ESCC metastasis and represents a new candidate therapeutic target for ESCC treatment.

Abstract
Phospholipase C epsilon 1 (PLCE1) is a susceptibility gene in esophageal squamous cell carcinoma (ESCC). Nevertheless, the role of PLCE1 in ESCC tumorigenesis has not been elucidated. In this study, we determined the function of PLCE1 and its regulatory microRNA (miRNA) in ESCC. PLCE1 protein was excessively expressed in ESCC and precancerous lesions compared with that in normal tissues. High PLCE1 expression levels in ESCC were significantly linked with poor overall survival. Knockdown of PLCE1 promoted the apoptosis, cytokine-induced apoptosis, and sensitivity of cancer cells to chemotherapeutic drugs but abrogated the proliferation and EMT phenotype of ESCC in vitro. Notably, miR-145 was newly identified as a potent repressor of PLCE1 expression by directly targeting the 3′UTR of PLCE1. MiR-145 also inhibited cell proliferation, migration, and metastasis, as well as controlled the cytoskeleton dynamics of esophageal cancer. Moreover, miR-145 was expressed at low levels in a large cohort of patients with ESCC and was inversely correlated with PLCE1 protein expression in cancer cells and tissues. These findings demonstrate that PLCE1 functions as tumor promoter in ESCC and can be suppressed by miR-145 through inhibition of PLCE1 translation. Hence, delivery of PLCE1-targeting miR-145 is a potential therapeutic approach for esophageal cancer.

Abstract
OBJECTIVE To explore the distribution characteristics of etiology and clinical feature of chronic cough in Lanzhou. METHODS Based on the guidelines of the diagnostic process of chronic cough in China, data of medical history and physical examinations were collected, and chest X-ray, pulmonary function plus airway hyperresponsiveness, induced sputum eosinophils, sinus X-ray or CT, 24 h esophageal pH monitoring, chest high-resolution CT and bronchoscopy were performed accordingly for outpatients with chronic cough. The cause of chronic cough was identified by the test results and treatment response. The results were compared with those reported previously in other areas of China. RESULTS A total of 173 patients with completed data were collected, including 90 males and 83 females.The causes were as follows: 45 cases (26.01%) of cough variant asthma, 35 (20.23%) upper airway cough syndrome, 20 (11.56%) allergic cough, 17 (9.83%) chronic pharyngitis, 14 (8.09%) gastroesophageal reflux, 14 (8.09%)postinfectious, 13 (7.51%) eosinophilic bronchitis, 8 (4.62%) chronic bronchitis, 4 (2.31%) cough associated with ACEI, 3 (1.73%) bronchial tuberculosis, 2 (1.16%) pulmonary fibrosis and bronchiectasis repectively. The causes of the remaining 14 patients (8.09%)were unknown. The causes of chronic cough were identified in 159 patients (91.91%), of which 141 (88.68%) with a single cause and 18(11.32%)with more than 2 etiological factors.The percentage of cough variant asthma in our series was significantly higher than that reported in Guangzhou (13.6%, χ(2)=5.60, P=0.018, P<0.05), but lower than that reported in Shenyang (39.4%, χ(2)=7.91, P=0, 004, P<0.01). The percentage of allergic cough was higher than that reported in Beijing (3.3%, χ(2)=6.66, P=0.010, P<0.05), and that of eosinophilic bronchitis was lower than those reported in Guangzhou(22.4%, χ(2)=22.38, P=0.000, P<0.01) and Shenyang (12.5%, χ(2)=8.09, P=0.005, P<0.01). The percentage of esophageal reflux cough was lower than that reported in Beijing (20.3%, χ(2)=9.40, P=0.002, P<0.01) but higher than that reported in Shenyang (1.9%, χ(2)=3.98, P=0.036, P<0.05). CONCLUSION In Lanzhou, cough variant asthma, upper airway cough syndrome, allergic cough, chronic pharyngitis and gastroesophageal reflux were the main causes of chronic cough, and the etiological distribution was different from Guangzhou, Beijing, Shenyang and other areas.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is one of the most aggressively malignant tumors with dismal prognosis. Profilin 2 (PFN2) is an actin-binding protein that regulates the dynamics of actin polymerization and plays a key role in cell motility. Recently, PFN2 have emerged as significant regulators of cancer processes. However, the clinical significance and biological function of PFN2 in ESCC remain unclear. Methods PFN2 protein expression was validated by immunohistochemistry (IHC) on tissue microarray from Chinese Han and Kazakh populations with ESCC. The associations among PFN2 expression, clinicopathological features, and prognosis of ESCC were analyzed. The effects on cell proliferation, invasion and migration were examined using MTT and Transwell assays. Markers of epithelial–mesenchymal transition (EMT) were detected by Western blot analysis. Results Compared with normal esophageal epithelium (NEE), PFN2 protein expression was markedly increased in low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia (HGIN), and ESCC, increased gradually from LGIN to ESCC, and finally reached high grade in HGIN in the Han population. Similarly, PFN2 protein was more overexpressed in ESCC than in NEE in the Kazakh population. The results of Western blot analysis also showed that PFN2 expression was significantly higher in the ESCC tissue than in a matched adjacent non-cancerous tissue. PFN2 expression was positively correlated with invasion depth and lymph node metastasis. High PFN2 expression was significantly correlated with short overall survival (OS) (P = 0.023). Cox regression analysis revealed that PFN2 expression was an independent prognostic factor for poor OS in ESCC. Downregulation of PFN2 inhibited, rather than proliferated, cell invasion and migration, as well as induced an EMT phenotype, including increased expression of epithelial marker E-cadherin, decreased mesenchymal marker Vimentin, Snail, Slug and ZEB1, and morphological changes in ESCC cells in vitro. Conclusions Our findings demonstrate that PFN2 has a novel role in promoting ESCC progression and metastasis and portending a poor prognosis, indicating that PFN2 could act as an early biomarker of high-risk population. Targeting PFN2 may offer a promising therapeutic strategy for ESCC treatment.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is a highly lethal cancer, and its underlying molecular mechanisms are poorly understood. Recent large-scale genome-wide association studies in Chinese Han populations have identified an ESCC susceptibility locus within the SLC39A6 gene. Here, we sought to explore the expression and biological function of SLC39A6 in ESCC. Methods Multiethnic validation of SLC39A6 protein expression was performed in different cohorts of patients from Chinese Han and Kazakh populations in the Xinjiang region by immunohistochemistry. The associations among SLC39A6 expression, clinicopathological parameters, and prognosis outcomes of ESCC were analyzed. And the effects of SLC39A6 silencing by siRNA on cell proliferation, apoptosis, and invasiveness, as well as the proteins involved in epithelial-to-mesenchymal transition (EMT) of esophageal cancer cells, were studied. Results SLC39A6 protein expression increased progressively from normal esophageal epithelium (NEE) to low-grade intraepithelial neoplasia to ESCC, and finally reached the highest in high-grade intraepithelial neoplasia from Han ethnic. Similarly, SLC39A6 protein was significantly overexpressed in Kazakh ethnic ESCC compared with that in NEE. Increased expression of SLC39A6 was found to be closely correlated with histological grade and early Tumor-Node-Metastasis stage I/II. High tumorous SLC39A6 expression was significantly correlated with shorter overall survival (OS). Cox regression analysis confirmed that SLC39A6 expression was an independent prognostic factor for poor OS in ESCC. Experimentally, the suppression of SLC39A6 expression promoted ESCC cell apoptosis but abrogated proliferation and invasion, and induced an EMT phenotype that included enhanced expression of E-cadherin, loss of vimentin, and morphological changes in ESCC cells in vitro. Conclusions Combined, our findings highlight a tumor-promoting role for SLC39A6 in ESCC, suggesting that SLC39A6 could serve as an early detector of high-risk subjects and prognostic biomarker. The targeting of SLC39A6 might be a potential therapeutic strategy for blocking ESCC.

Abstract
BACKGROUND Many studies have suggested a relationship between human papillomavirus (HPV) infection and the risk of esophageal squamous cell carcinoma (ESCC). However, findings are inconclusive, potentially because of geographic heterogeneity and variations in detection methods. OBJECTIVES We sought to further investigate the prevalence of HPV with a new detection method, the MassARRAY Sequenom technique, in esophageal squamous cell carcinomas occurring in patients belonging to Kazakh populations in Xinjiang, China. STUDY DESIGN In the present study, a novel genotyping method for detecting 30 HPV genotypes, specifically by genotyping both the HPV E6 and L1 genes with multiplex PCR using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) (PCR-MS) was first adopted to evaluate HPV genotypes in 89 esophageal cancer samples and 49 matched adjacent normal esophageal tissues. RESULTS Six HPV genotypes (HPV6, HPV16, HPV33, HPV39, HPV51, and HPV82) were present in at least 51.7% of the esophageal carcinoma tissues, which was significantly greater than 28.6% prevalence among controls (P < 0.05). HPV16 was the most common of all the genotypes investigated (HPV16 prevalence in carcinoma tissue: 49.4%; odds ratio 3.02, 95% confidence interval 1.39-6.53). HPV-positive ESCC patients were generally younger than HPV-negative patients (P = 0.04). In addition, HPV infection was more common in cases of well-differentiated and shallower invasive depth. CONCLUSIONS Based on this new detection method, our findings reiterate the possibility that HPV infection (especially HPV16) may be involved in the etiology of esophageal carcinoma in the Kazakh populations and that HPV E6 gene positivity may be associated with prognosis of patients.

Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is a malignant tumor with a strong tendency toward familial aggregation and a higher incidence as well as mortality in Kazakh population. Tumor necrosis factor-alpha (TNF-α) is an important inflammatory cytokine that plays a role in controlling the progression of lung cancer, hepatocellular cancer, breast cancer and gastric cancer. But the association between TNF-α-308G/A and ESCC still remains unclarified. MATERIALS AND METHODS Here, we investigated the potential associations between the TNF-α-308G/A and susceptibility to ESCC in 212 cases and 200 controls from a pure ethnic population of Kazakh. DNA extraction and Real-time PCR were performed to detect the TNF-α-308G/A expression levels and odd ratios (ORs) with the corresponding 95% confidence interval (CI) were to evaluate their association with TNF-α-308G/A polymorphism. RESULTS We found that the frequencies of TNF-α-308G/A in the cases were similar to that of the controls with no differences being statistically significant (χ(2)=1.23, P>0.05). Using the G allele as the reference genotype, individuals who carried A allele had a significantly increased risk of developing ESCC (OR=2.64, 95% CI=1.31~5.35). Especially, the G/A+A/A genotype are associated with increased risk of metastatic as compared with GG genotype individuals (OR=2.08, 95% CI=1.14-3.80, P=0.02). CONCLUSIONS Our findings suggest that though the TNF-α-308G/A polymorphism may not be correlated with the susceptibility to Kazakh's ESCC in Xinjiang, patients who carry A allele tend to poorly differentiated and lymph node metastasis.

Abstract
Voltage controlled 180° magnetization reversal has been achieved in BiFeO3-based multiferroic heterostructures, which is promising for the future development of low-power spintronic devices. However, all existing reports involve the use of an in-plane voltage that is unfavorable for practical device applications. Here, we investigate, using phase-field simulations, the out-of-plane (i.e., perpendicular to heterostructures) voltage controlled magnetism in heterostructures consisting of CoFe nanodots and (110) BiFeO3 thin film or island. It is predicted that the in-plane component of the canted magnetic moment at the CoFe/BiFeO3 interface can be reversed repeatedly by applying a perpendicular voltage across the bottom (110) BiFeO3 thin film, which further leads to an in-plane magnetization reversal in the overlaying CoFe nanodot. The non-volatility of such perpendicular voltage controlled magnetization reversal can be achieved by etching the continuous BiFeO3 film into isolated nanoislands with the same in-plane sizes as the CoFe nanodot. The findings would provide general guidelines for future experimental and engineering efforts on developing the electric-field controlled spintronic devices with BiFeO3-based multiferroic heterostructures.

Abstract
Purpose To conduct a meta-analysis to evaluate the prognostic role of E-cadherin expression in bone and soft tissue sarcomas. Methods The PubMed, EMBASE, and Web of Science databases were searched using terms related to E-cadherin, sarcoma, and prognosis for all articles published in English before March 2014. Pooled effect was calculated from the available data to evaluate the association between negative E-cadherin expression and 5-year overall survival and tumor clinicopathological features in sarcoma patients. Pooled odds ratios (OR) and risk ratios (RR) with 95% confidence intervals (CI) were calculated using a fixed-effects model. Result Eight studies met the selection criteria and reported on 812 subjects. A total of 496 subjects showed positive E-cadherin expression (59.9%). Negative E-cadherin expression in bone and soft tissue sarcomas was correlated with lower 5-year overall survival (OR = 3.831; 95% CI: 2.246–6.534), and was associated with higher clinical stage (RR = 1.446; 95% CI: 1.030–2.028) and with male sex (RR = 0.678; 95% CI: 0.493–0.933). Conclusion In the E-cadherin negative group, 5-year overall survival was significantly worse than in the E-cadherin positive group. However, further studies are required to confirm these results.

Abstract
Emerging evidence suggests that activation of the Notch1 signaling pathway inducing epithelial to mesenchymal transition (EMT) mediated by Snail/Slug promotes invasion and metastasis of breast cancer cells in vitro. However, the implication of the Notch1-Snail/Slug-EMT axis in breast cancer patients remains unclear. A total of 200 formalin-fixed paraffin-embedded samples of invasive ductal carcinoma (IDC), and 37 adjacent non-neoplastic tissue (ANNT) samples from patients who had not been treated with neoadjuvant therapy were examined. Expression of Notch1, Slug, Snail, E-cadherin, N-cadherin, and vimentin was determined by immunohistochemistry on tissue microarrays (TMAs). The correlation between protein expression and clinicopathological characteristics of breast cancer patients was also evaluated. Results showed that a significantly high percentage of cases with high expression of Notch1 (74%, 148/200), Slug (36%, 72/200), Snail (62%, 124/200), and N-cadherin (77%, 153/200) and a low percentage of cases with high expression of E-cadherin (27%, 54/200) were observed in IDC compared to those in ANNTs. High Notch1, Slug, Snail, and N-cadherin expression and low E-cadherin expression in patients with IDC were significantly correlated with lymph node metastasis. In addition, correlation analysis results revealed that high Notch1 expression was significantly associated with high Slug, Snail, and N-cadherin expression and low E-cadherin expression in IDC. Furthermore, a high Snail expression was significantly associated with low E-cadherin expression, and a high Slug expression was found to be significantly associated with increased N-cadherin expression in patients with IDC. Hence, our study suggested that the Notch1-Snail/Slug-EMT axis may be implicated in the lymph node metastasis affecting patients with IDC.

Abstract
The rhabdomyosarcoma (RMS) is the most common type of soft tissue tumor in children and adolescents; yet only a few screens for oncogenic mutations have been conducted for RMS. To identify novel mutations and potential therapeutic targets, we conducted a high-throughput Sequenom mass spectrometry-based analysis of 238 known mutations in 19 oncogenes in 17 primary formalin-fixed paraffin-embedded RMS tissue samples and two RMS cell lines. Mutations were detected in 31.6% (6 of 19) of the RMS specimens. Specifically, mutations in the NRAS gene were found in 27.3% (3 of 11) of embryonal RMS cases, while mutations in NRAS, HRAS, and PIK3CA genes were identified in 37.5% (3 of 8) of alveolar RMS (ARMS) cases; moreover, PIK3CA mutations were found in 25% (2 of 8) of ARMS specimens. The results demonstrate that tumor profiling in archival tissue samples is a useful tool for identifying diagnostic markers and potential therapeutic targets and suggests that these HRAS/ PIK3CA mutations play a critical role in the genesis of RMS.

Abstract
Unclassified renal cell carcinoma (URCC) is a rare variant of RCC, accounting for only 3-5% of all cases. Studies on the molecular genetics of URCC are limited, and hence, we report on 2 cases of URCC analyzed using comparative genome hybridization (CGH) and the genome-wide human exon GeneChip technique to identify the genomic alterations of URCC. Both URCC patients (mean age, 72 years) presented at an advanced stage and died within 30 months post-surgery. Histologically, the URCCs were composed of undifferentiated, multinucleated, giant cells with eosinophilic cytoplasm. Immunostaining revealed that both URCC cases had strong p53 protein expression and partial expression of cluster of differentiation-10 and cytokeratin. The CGH profiles showed chromosomal imbalances in both URCC cases: gains were observed in chromosomes 1p11-12, 1q12-13, 2q20-23, 3q22-23, 8p12, and 16q11-15, whereas losses were detected on chromosomes 1q22-23, 3p12-22, 5p30-ter, 6p, 11q, 16q18-22, 17p12-14, and 20p. Compared with 18 normal renal tissues, 40 mutated genes were detected in the URCC tissues, including 32 missense and 8 silent mutations. Functional enrichment analysis revealed that the missense mutation genes were involved in 11 different biological processes and pathways, including cell cycle regulation, lipid localization and transport, neuropeptide signaling, organic ether metabolism, and ATP-binding cassette transporter signaling. Our findings indicate that URCC may be a highly aggressive cancer, and the genetic alterations identified herein may provide clues regarding the tumorigenesis of URCC and serve as a basis for the development of targeted therapies against URCC in the future.

Abstract
Accumulated evidence has revealed the presence of Notch receptor polymorphisms in non-tumorous diseases; however, few studies have investigated the association of Notch polymorphisms with breast cancer risk. A total of 100 invasive ductal carcinoma (IDC) and 50 ductal carcinoma in situ (DCIS) patients and 100 usual ductal hyperplasia (UDH) controls were genotyped for the following Notch receptor single nucleotide polymorphisms (SNPs) using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry: Notch1, rs3124591; Notch2, rs11249433; Notch3, rs3815188, and rs1043994; and Notch4, rs367398, and rs520692. Immunohistochemistry was used to determine the effect of Notch polymorphisms on corresponding Notch protein expression in successfully genotyped patients. The frequency of rs3124591 TC genotype was significantly higher in IDC (24.7%, 20/81) and DCIS (30%, 12/40) patients than in UDH controls (8%, 8/97) (P = 0.002 and P = 0.011, respectively). However, the distribution of other SNP genotypes was not significantly different between IDC and DCIS patients and UDH controls. The frequency of TC genotype was significantly higher in poorly differentiated tumors than in well-differentiated and moderately differentiated tumors (P = 0.022). Importantly, a positive correlation between the rs3124591 TC genotype and high Notch1 protein expression was observed in DCIS patients (P = 0.043) but not in IDC patients. This is the first study to suggest an increased risk of IDC and DCIS of the breast for the Notch1 rs3124591 variant. Furthermore, given the inconsistent associations between the rs3124591 variant and Notch1 expression in IDC and DCIS, this variant may affect breast cancer risk through mechanisms in the latter stage other than alterations in Notch1 protein expression.

Abstract
Voltage-modulated magnetism in magnetic/BiFeO3 heterostructures can be driven by a combination of the intrinsic ferroelectric-antiferromagnetic coupling in BiFeO3 and the antiferromagnetic-ferromagnetic exchange interaction across the heterointerface. However, ferroelectric BiFeO3 film is also ferroelastic, thus it is possible to generate voltage-induced strain in BiFeO3 that could be applied onto the magnetic layer across the heterointerface and modulate magnetism through magnetoelastic coupling. Here, we investigated, using phase-field simulations, the role of strain in voltage-controlled magnetism for these BiFeO3-based heterostructures. It is predicted, under certain condition, coexistence of strain and exchange interaction will result in a pure voltage-driven 180° magnetization reversal in BiFeO3-based heterostructures.

Abstract
Synovial sarcoma (SS) is a malignant tumor of soft tissue and is noted for late local recurrence and metastasis. Aberrant epithelial-mesenchymal transition (EMT) has been implicated in the pathogenesis of diverse human malignancies. Immunohistochemical techniques were used to assess EMT-related proteins (E-cadherin, N-cadherin, β-catenin, Snail, and Slug) and the TGF-β1 pathway (TGF-β1 and Smad2/3) proteins expression in different histological subtypes and epithelial mesenchymal compositions of SS. The expression of cell-surface (E-cadherin) and cytoskeletal proteins (β-catenin) were higher significantly in biphasic SSs (BSSs) (70.4%, 51.9%) than MFSSs (both for 10%). Among monophasic fibrous SSs (MFSSs) samples, E-cadherin protein expression was negatively correlated with expression Snail, Slug, TGF-β1, and Smad2/3. The expression levels of Snail and Smad2/3 were correlated with the pTNM stage (I-II vs. III-IV; P=0.047, P=0.021) and TGF-β1 exhibited a tendency toward a positive correlation with pTNM stage (I-II vs. III-IV; P=0.052), but did not correlate with the histological grade (p>0.05). Interestingly, our data showed that expression of E-cadherin protein correlated with greater survival in SS patients. Overexpression of Snail, and TGF-β1 is associated with suppressed expression of E-cadherin in MFSSs, which supports the hypothesis that the MFSS subtype may have developed via neoplastic EMT.

Abstract
Although recent genome-wide association studies of esophageal squamous cell carcinoma (ESCC) identified a susceptibility locus in phospholipase C epsilon 1 (PLCE1) in Chinese Han populations, few studies further confirmed these findings in pure Kazakh population in which there are higher incidence and mortality of ESCC. Here, we investigated the potential associations between 19 SNPs of PLCE1 and susceptibility to ESCC in 222 cases and 326 controls from a pure ethnic population of Kazakh. Real-time PCR and immunohistochemistry were performed to detect the PLCE1 expression levels and evaluate their association with PLCE1 polymorphism. We found that only 4 SNPs (rs753724, rs11187842, rs2274223, and rs12263737) with moderate linkage disequilibrium (LD) confer significantly increased risk of ESCC, with the ORs ranging from 1.43 to 2.04, and there was a risk allele dose-dependent increase in ESCC risk (P-trend=0.043). Especially, the risk effects of rs2274223 were more evident in poor differentiation and advanced clinical stages of Kazakh ESCC. Additionally, the significantly lowest PLCE1 mRNA expression was found in the KYSE-150 cell line having no risk alleles compared with other three cell lines having risk alleles, and the normal tissues of both homozygous mutant type of PLCE1 rs12263737 and rs2274223 had a higher PLCE1 staining score than that of homozygous wild type. Our findings suggested that genetic variants in PLCE1 might serve as candidate markers for Kazakh ESCC susceptibility, and these LD variants might influence ESCC risk individually and jointly by promoting the messenger RNA and protein expression of the gene.

Abstract
Diffuse large B-cell lymphoma (DLBCL) usually present with rapidly growing lymph nodes or extra-nodal masses. Central nerve system involvement and pregnancy are rare in DLBCL. Here, we report an unusual case of DLBCL with cavernous sinus syndrome during pregnancy. A 24-year-old woman presented cavernous sinus syndrome as the initial presentation during pregnancy. Magnetic resonance imaging (MRI) revealed enlargement of bilateral cavernous sinus. Tonsil and ovary biopsy indicated malignant lymphoma-DLBCL. Bone marrow smear showed infiltration by tumor cells. The case delivered a viable baby by cesarean section and then took chemotherapy of rituxan, cyclophosphamide, adriamycin, eldisine and dexamethasone. The disease deteriorated rapidly, especially after the pregnancy was terminated. Fortunately, a complete response was achieved after six cycles of chemotherapy. With the accumulation of clinical practice of such cases, we would be able to recognize minimal symptoms of DLBCL at the beginning and confirm the most suitable timing of the initiation of chemotherapy during pregnancy.

Abstract
Soft tissue sarcomas (STSs) are a rare and fascinating group of diseases that can be subdivided into specific reciprocal translocations in STSs (SRTSs) and nonspecific reciprocal translocations in STSs (NRTSs). PTEN mutations are rare in STSs, suggesting that PTEN expression may be lost by alternative mechanisms such as methylation. In order to reveal whether aberrant PTEN methylation occurs in STSs, MassARRAY Spectrometry was carried to detect methylation patterns of PTEN in STSs. We evaluated methylation levels in 41 CpG sites from −2,515 to −2,186 bp (amplicon A) and −1,786 to −1,416 bp (amplicon B) relative to the translation initiation site in 110 different cases (46 cases of SRTSs, 40 cases of NRTSs, and 24 cases of normal controls). In addition, immunohistochemistry (IHC) was used to detect the loss of PTEN to determine whether PTEN alterations were responsible for decreased PTEN expression. Our data showed that expression of PTEN was diminished in 49 (57%) STSs, whereas the remaining cases (43%) were classified as high expression. Our previous results found that only 2 of 86 cases (2.3%) had a PTEN mutation suggesting that PTEN may be mainly downregulated in STSs by methylation, but not by mutation of PTEN itself. We observed that amplicon A was hypermethylated in STSs with low PTEN expression, whereas normal controls had low methylation levels (P<0.0001), which was not present in amplicon B (P>0.05), nor were there significant differences in the methylation levels in PTEN between SRTS and NRTS cases. The majority of individual CpG units within two amplicons was demonstrated to be hypermethylated. These findings indicate that PTEN hypermethylation is a common event in STSs suggesting that the inactivation of PTEN may be due to hypermethylation in the promoter of PTEN. The aberrant methylation of the CpG sites within PTEN promoter may serve as a potential candidate biomarker for STSs.

Abstract
Three recent large-scale genome-wide association studies (GWAS) in Chinese Han populations have identified an esophageal squamous cell carcinoma (ESCC) susceptibility locus within phospholipase C epsilon 1 (PLCE1) gene, which encodes a phospholipase involved in intracellular signaling. The expressed PLCE1 in ESCC, however, are inconsistent. This study examined PLCE1 expression by immunohistochemistry (IHC) from 110 ethnic Kazakh ESCC patients and 50 from adjacent normal esophageal tissues (NETs). The expressed PLCE1 was localized in cytoplasm, especially in the peripheral layers of cancer cell nests, which was significantly higher in tumors than in NETs (p < 0.001). Increased expression of PLCE1 was correlated with advanced tumor-node-metastasis (TNM) stages (p = 0.015) and lymph node metastasis (p = 0.003) in patients with ESCC. Of the 110 patients, we examined 50 paired ESCC tissues and corresponding NETs by quantitative RT-PCR (polymerase chain reaction) and the mean mRNA level of PLCE1 in ESCC was 1.85-fold higher compared with those in corresponding NETs (p = 0.0012). Meanwhile, 4 of 5 ESCC cell lines also showed elevated expression of PLCE1 mRNA. Furthermore, elevated expression of PLCE1 mRNA in Kazakh ESCC was associated with its immunoreactivity (ρ = 0.297, p = 0.040), lymph node metastasis (p < 0.001), and advanced TNM stages of ESCC (p = 0.013). To our knowledge, this study demonstrates for the first time that PLCE1 overexpression correlates with lymph node metastasis and advanced TNM stages of Kazakh ESCC, implicating a role of PLCE1 in cancer metastasis and aggressiveness in ethnic Kazakh patients with ESCC. Furthermore, the current findings may warrant investigations into whether inhibiting PLCE1 could be a strategy for targeted anticancer therapy particularly for Kazakh ESCC.

Abstract
The aim of this study was to investigate human papillomavirus type 16 (HPV16) prevalence in esophageal squamous cell carcinoma (ESCC) in Xinjiang Kazakh patients and its role in ESCC carcinogenesis. One hundred and fifty cases of ESCC and 150 cases of corresponding normal esophageal mucosa (CNGM) samples were collected from north Xinjiang where the Kazakh ethnic group has lived since ancient times. HPV16 infection in ESCC and CNGM was detected by genotype-specific polymerase chain reaction. HPV16 DNA was detected in 55 of 150 ESCC samples (36.7%) and 24 of 150 corresponding normal esophageal mucosa samples (16%) with significant differences (P < 0.001, odds ratio = 3.039, 95% confidence interval: 1.756-5.260). No statistically significant correlations were found between HPV16 infection and the age or gender of patients, tumor site, tumor cell differentiation, or lymph node metastasis (P > 0.05). HPV16 infection is common in cases of ESCC in the Kazakh ethnic group in Xinjiang and may be involved in ESCC carcinogenesis.

Abstract
OBJECTIVE To study the expression of the epidermal growth factor receptor (EGFR) and the oncogene c-erbB2 on pulmonary fibrosis induced by bleomycin (BLM) in rats. METHODS Fifty-four Wistar rats were randomly divided into three groups, the pulmonary fibrosis group (BLM), Iressa group and the control group. There were 18 rats in each group. Control group were injected with saline 0.2-0.3 ml in trachea. Iressa group and BLM group were injected with BLM intratracheal. After the fibrosis models were build, Iressa group were given orally Iressa (200 mg/kg)1 h before modeling in Iressa group, saline were fed 10 ml/kg in BLM group and control group. The three groups were fed 5 times per week; and were sacrificed after treatment on days 1, 14 and 28 respectively. The lungs were harvested for histological studies. RESULTS The lung tissue in Iressa group showed fibrosis and inflammatory cell infiltration, the same as shown in the BLM group. The pulmonary fibrosis score was significantly lower than the BLM group on the 28 th day (2.17 +/- 0.41 vs 3.50 +/- 0.84, P < 0.01). Compared with the control group, c-erbB2 and EGFR were hyper expressed significantly both in BLM group and Iressa group at all time points (P < 0.01); c-erbB2 expression had no changes between the Iressa group and the BLM (P > 0.05), that were gradually decreased, and was significantly different at each time point (P < 0.01). EGFR expression was increased gradually on the 14th and 28th day (0.17 +/- 0.02 and 0.28 +/- 0.04) in Iressa group ,that was significantly lower than the BLM group (0.27 +/- 0.04 and 0.34 +/- 0.02) (P < 0.01). EGFR expression increased significantly on the 28th day than on the 14th day in the Iressa group (P < 0.01). CONCLUSION The expression of C-erbB2 and EGFR are enhanced in different stages of alveolitis and pulmonary fibrosis, c-erbB2 and EGFR may be participated in different stages of pulmonary fibrosis.

Abstract
CD40 is expressed in many tumor cells, however, its role in tumor biology is yet to be demonstrated. In the present study, we investigated the role of CD40 in cervical carcinoma. In vivo, we evaluated CD40 expression in 56 cervical carcinoma tissues, 43 cervicitis and 38 normal cervix, and investigated the relationship between CD40 and HPV antigen, histopathological parameters, vascular density, and vascular endothelial growth factor (VEGF) expressions. The results clearly demonstrated that CD40 expression, including membranous and cytoplasmic staining, was significantly higher in cervical carcinoma than in the cervicitis and normal cervix. The expression of CD40 was significantly correlated with HPV and VEGF expressions and microvessel density (MVD). These observations provide evidence that CD40 may be involved in neovascularization of cervical carcinoma, they also suggest that CD40 and VEGF may be useful biomarkers for evaluating the risk of developing cervical carcinoma, and may also be used as a target for therapy.

Abstract
CD40, a member of the tumor necrosis factor receptor superfamily, is widely expressed on various cell types. Some studies show that CD40 expression is related to several carcinomas, where its function remains largely unknown. This study investigated the expression of CD40 on cervical carcinoma and evaluated the effect of agnostic anti-CD40 mAb (5C11) on tumor cell line (SiHa). CD40 expression on the primary cervical carcinoma samples was detected by immunohistochemistry. Results showed that CD40 is commonly expressed in human cervical carcinoma, which is higher than that of normal cervix, cervical precancerous tissue and chronic cervicitis. Treatment of the SiHa cell with the agonistic anti-CD40 monoclonal antibody or Gemcitabine alone did not inhibit the proliferation of the SiHa cell in vitro, but the activation of CD40 on SiHa could enhance its sensitivity to Gemcitabine. Furthermore, CD40 activation blocked SiHa in the S phase, stimulated proapoptotic Bax and inhibited antiapoptotic Bcl-XL mRNA synthesis in the SiHa cell. Apoptosis in SiHa was associated with an increasing ratio of Bax to Bcl-XL in mRNA levels. It is concluded that use of the anti-CD40 mAb 5C11 in combination with chemotherapy may have significant therapeutic potential.

Abstract
INTRODUCTION A longitudinal study was established to investigate bone compositional information in spinal cord injury (SCI) rat model. METHODS Raman spectroscopy was applied to detect the distal femur and humeri of SCI, sham-operated (SO), and age-matched control (CON) male Sprague-Dawley (SD) rats at first, second, third, and fifth weeks after surgery. One-way ANOVA and Tukey's HSD post hoc multiple comparison tests were used to analyze the longitudinal data of mineral to matrix ratio and carbonate substitution. RESULTS Relative mineral decrease was found in SCI group by more than 20% in femur and approximately 12% in humeri compared with CON group. No significant changes in carbonate substitution were observed. CONCLUSIONS Severe bone loss in the early stage of SCI was confirmed by a continuous decrease of the mineral to collagen matrix ratio. The decrease in the humeri suggested hormone level variations might participate in the etiology of SCI-induced osteoporosis.

Abstract
OBJECTIVE To study the mechanisms of N-acetylcysteine (NAC) in the inhibition of proliferation and collagen synthesis of human pulmonary fibroblasts. METHODS The human pulmonary fibroblasts (HFB) were primarily cultured in complete medium of DMEM/F12, with the cell line A549 derived from alveolar epithelia as the control. Different concentrations of NAC were administrated, with or without stimulation by TGF-beta(1) for 24 h. The cell proliferations were tested by methylthiazolyltetrazolium (MTT) and cell cycle detected with flow cytometer. The mRNA expression of type I procollagen was tested with RT-PCR. Proteins of cyclin E, alpha-SMA and STAT-3 were detected with Western blotting. RESULTS The proliferation of HFB was inhibited significantly by NAC at different concentrations (5, 10, 20 and 40 mmol/L). NAC had no effects on proliferation of A549 at a dose of 20 mmol/L. The cell proportion in G(0)/G(1) phase was increased by NAC at different concentrations (10, 20 and 40 mmol/L), while the changes in S-phase ratio were decreased significantly. Procollagen type Isynthesis was increased by TGF-beta(1) significantly. NAC showed inhibition on procollagen type I synthesis before or after stimulation with TGF-beta(1). Expression of protein cyclin E and alpha-SMA was significantly induced by TGF-beta(1), the relative indensity being 0.98 +/- 0.09 and 1.56 +/- 0.23 respectively. Induction of cyclin E by TGF-beta(1) was attenuated significantly by NAC 20 mmol/L (0.52 +/- 0.04). But alpha-SMA was not changed by NAC 20 mmol/L (1.63 +/- 0.20). Stimulation with TGF-beta(1) and NAC had no effects on expression of STAT-3. CONCLUSIONS Inhibition on proliferation of HFB by NAC may be through the attenuation of cyclin E. Differentiation of fibroblasts into myofibroblasts was inhibited by NAC through inhibition on alpha-SMA. NAC directly inhibited collagen synthesis.

Abstract
1. Currently, there is no satisfactory treatment for pulmonary fibrosis. Emodin, a component in Chinese herbs, has been shown to have an antifibrotic effect on pancreatic fibrosis and liver fibrosis. In the present study, we tested the hypothesis that emodin may attenuate the development of pulmonary fibrosis. 2. Mice were randomly divided into five groups (n = 16 in each). One group was a control group; the remaining four groups were treated with intratracheal instillation of 3 mg/kg bleomycin (BLM). The following day, emodin (5, 10 or 20 mg/kg per day, p.o.) treatment was started for three of the BLM-treated groups and was continued for 21 days. The fourth BLM-treated group (and the control group) received daily 0.5% sodium carboxymethyl cellulose (placebo) by gavage over the same period. 3. Bleomycin challenge provoked severe pulmonary fibrosis, with marked increases in fibrosis fraction, hydroxyproline content and myeloperoxidase activity in lung tissue. Emodin treatment (10 and 20 mg/kg per day, p.o.) attenuated all these biochemical indices, as well as histopathological alterations induced by BLM. Furthermore, in mice injected with BLM, elevated levels of transforming growth factor-beta1, interleukin (IL)-4 and IL-13 were found in bronchoalveolar lavage fluid. These increases were significantly inhibited by 10 and 20 mg/kg per day emodin. 4. In cell culture, exposure of cells to 6.25, 12.5, 25 or 50 micromol/L emodin for 24 h decreased fibroblast proliferation. Treatment of cells with the same concentrations of emodin for 72 h decreased collagen production by fibroblasts. In addition, emodin (6.25, 12.5, 25 or 50 micromol/L) inhibited the steady state expression of alpha1 (I) procollagen and alpha2 (I) procollagen mRNA in a dose-dependent manner. 5. The results of the present study suggest that emodin may be effective in the treatment of pulmonary fibrosis.

Abstract
Using first-principles calculations, we investigate the effect of tube size on optical properties of the zigzag, armchair, and chiral SiC nanotubes. The results indicate that the optical spectra of SiC nanotubes are dependent on the diameter and chirality, and that optical anisotropy is observed for different light polarizations. For a given chirality of SiCNTs, redshifts or blueshifts of the peaks in the dielectric function and energy loss function with increasing tube diameter are possible due to the competition between the size effect and pi orbitals overlapping, and the shifts become smaller as the tube diameter increases. The unusual optical properties of semiconducting SiC nanotubes present an opportunity for applications in electro-optical devices.

Abstract
The staphylococcal chromosome cassette (SCC)mec types of 382 hospital-acquired methicillin-resistant Staphylococcus aureus (HA-MRSA) isolates in Taiwan were analysed over a 7-year period (1999-2005). There was an abrupt increase in SCCmec type IV in HA-MRSA during 2005. The molecular epidemiology of a subset (n = 69) of HA-MRSA isolates with SCCmec types III, IV or V was characterised and compared with that of community-acquired MRSA (CA-MRSA) (n = 26, collected during 2005). Pulsed-field gel electrophoresis revealed three major pulsotypes (A, B and C) and 15 minor clones. Pulsotypes B and C, which contained isolates carrying SCCmec types IV and V, respectively, included both CA-MRSA and HA-MRSA isolates. Among 24 toxin genes analysed, five genes had significant differential distribution between CA-MRSA and SCCmec type III HA-MRSA. Furthermore, among SCCmec type IV isolates, the seb gene was detected more commonly in HA-MRSA. Analysis of representative members of the three major pulsotypes by multilocus sequence typing revealed two sequence types (STs), namely ST239 (SCCmecIII) and ST59 (SCCmecIV or SCCmecV). This suggests that ST59:SCCmecIV, which is usually community-acquired, has become an important nosocomial pathogen in the hospital studied.

Abstract
The aim of the study is to determine the role of lymphadenectomy in advanced epithelial ovarian cancer. The data were obtained from the Surveillance, Epidemiology and End Results (SEER) program reported between 1988 and 2001. Kaplan–Meier estimates and Cox proportional hazards regression models were used for analysis. Of 13 918 women with stage III–IV epithelial ovarian cancer (median age: 64 years), 87.9% were Caucasian, 5.6% African Americans, and 4.4% Asians. A total of 4260 (30.6%) underwent lymph node dissections with a median number of six nodes reported. For all patients, a more extensive lymph node dissection (0, 1, 2–5, 6–10, 11–20, and >20 nodes) was associated with an improved 5-year disease-specific survival of 26.1, 35.2, 42.6, 48.4, 47.5, and 47.8%, respectively (P<0.001). Of the stage IIIC patients with nodal metastases, the extent of nodal resection (1, 2–5, 6–10, 11–20, and >20 nodes) was associated with improved survivals of 36.9, 45.0, 47.8, 48.7, and 51.1%, respectively (P=0.023). On multivariate analysis, the extent of lymph node dissection and number of positive nodes were significant independent prognosticators after adjusting for age, year at diagnosis, stage, and grade of disease. The extent of lymphadenectomy is associated with an improved disease-specific survival of women with advanced epithelial ovarian cancer.

Abstract
Salmonella enterica serovar Typhi is an important pathogen exclusively for humans and causes typhoid or enteric fever. It has been shown that type IVB pili, encoded by the S. enterica serovar Typhi pil operon located in Salmonella pathogenicity island 7, are important in the pathogenic process. In this study, by using both an adhesion-invasion assay and fluorescence quantitative PCR analysis, we demonstrated that the entry of type IVB piliated S. enterica serovar Typhi A21-6 (pil(+) Km(r)) into human THP-1 monocytic cells was greater than that of a nonpiliated S. enterica serovar Typhi pilS::Km(r) (pil mutant) strain. We have applied a systematic evolution of ligands by exponential enrichment approach to select oligonucleotides (aptamers) as ligands that specifically bind to type IVB pili. Using this approach, we identified a high-affinity single-stranded RNA aptamer (S-PS(8.4)) as a type IVB pilus-specific ligand and further found that the selected aptamer (S-PS(8.4)) could significantly inhibit the entry of the piliated strain (but not that of the nonpiliated strain) into human THP-1 cells. The binding affinities between aptamers and pre-PilS (structural protein of type IVB pili) were determined by nitrocellulose filter-binding assays, and the K(d) value was determined to be 8.56 nM for the S-PS(8.4) aptamer alone. As an example of an aptamer against type IVB pili of S. enterica serovar Typhi, the aptamer S-PS(8.4) can serve as a tool for analysis of bacterial type IVB pilus-host cell interactions and may yield information for the development of putative new drugs against S. enterica serovar Typhi bacterial infections, useful both in prevention of infection and in therapeutic treatment.

Abstract
Although intraoperative transoesophageal echocardiography (TOE) has an established role in the management of some cardiac surgical procedures, there is little data on its impact on coronary artery bypass graft (CABG) cases that are stratified for clinical risk. This is a retrospective review of the surgical impact of intraoperative TOE on 2,343 unselected cardiac cases. The surgical impact of TOE findings were rated E (essential)--resulted in changes to the proposed surgical procedure or V (valuable)--the surgical technique for the planned surgery was altered. The surgical impact that routine TOE had on low-, medium- and high-risk CABG cases was also examined. The surgical impact of TOE for the total study population (E + V) was 4.5%. The impact was greatest in combined CABG + mitral valve procedures (18%). The impact in CABG cases was 3.5% overall, with an estimated impact in low-risk patients of 2.8% (95% CI. 2.7-3.0%) versus 6.7% (95% CI. 5.9-7.7%) in high-risk cases. The commonest E-impact in CABG patients was unscheduled valve surgery (2.6% of high-risk patients). The complication rate attributable to TOE was 0.09%. These findings provide indirect evidence for a potential patient benefit from the routine use of TOE in cardiac surgery.

Abstract
Complexes CuGlu, ZnGlu, NiGlu, Fe(III) Glu, Co(III) Glu where Glu is d-glucosamine have been synthesized. The effects of these compounds on DNA have been studied by the UV-Vis, fluorescence and SERS methods. The possible active ways of these complexes with DNA have been discussed. The results show that the adsorbed state of these complexes on silver sols are similar, and that CuGlu, Co(III) Glu have strong interactions with DNA. Their acting ways on DNA are different. It is worth to do a further research on these compounds as anticancer drugs.

Abstract
Our previous report demonstrated that high concentration of taurine is present in rat milk for the first few days of lactation and plays an important role in the body growth of rat pups. In the present study, gene expression of rate-limiting enzyme for taurine biosynthesis, cysteine sulfinate decarboxylase (CSD) were examined in rat mammary gland. By RT-PCR, CSD mRNA was found to be expressed in rat mammary gland like that in the liver. The expression level of CSD mRNA in the mammary gland was higher in the earlier lactational stage (days 1 and 6 of lactation) than that in the later lactational stage (day 14). CSD mRNA expression in the mammary gland of non-pregnant rats was only a trace level. By in situ hybridization analysis, CSD mRNA was demonstrated in the epithelial cells of the mammary gland. These results suggest that high concentrations of taurine in the milk are at least partially resulted from de novo synthesis of taurine in mammary gland epithelial cells and that the expression pattern of CSD mRNA may be responsible for the changes in taurine levels in the milk during a lactational period.
