Abstract
Objective: To investigate the clinicopathological factors and clinical significance of (micro)metastasis in No.12b lymph node in patients with gastric antrum cancer. Methods: This was a retrospective cohort study of data of 242 patients with gastric adenocarcinoma without distant metastasis, complete follow-up data, and no preoperative anti-tumor therapy or history of other malignancies. All study patients had undergone radical gastrectomy (at least D2 radical range) + No.12b lymph node dissection in the Department of Gastric Surgery of Liaoning Cancer Hospital from January 2007 to December 2012. Immunohistochemical staining with antibody CK8/18 was used to detect micrometastasis to lymph nodes. Patients with positive findings on hematoxylin and eosin stained specimens and/or CK8/18 positivity in No.12b lymph node were diagnosed as having No.12b (micro)metastasis and included in the No.12b positive group. All other patients were classified as 12b negative. We investigated the impact of No.12b (micro)metastasis by comparing the clinicopathological characteristics and recurrence free survival (RFS) of these two groups of patients and subjecting possible risk factors to statistical analysis. Results: Traditional hematoxylin-eosin staining showed that 15/242 patients were positive for No.12b lymph nodes and 227 were negative. A total of 241 negative No. 12b lymph nodes were detected. Immunohistochemical testing revealed that seven of these 241 No.12b lymph nodes (2.9%) were positive for micrometastasis. A further seven positive nodes were identified among the 227 nodes (3.1%) that had been evaluated as negative on hematoxylin-eosin-stained sections. Thus, 22 /242 patients' (9.1%) No.12b nodes were positive for micrometastases, the remaining 220 (90.9%) being negative. Factor analysis showed that No.12b lymph node (micro) metastasis is associated with more severe invasion of the gastric serosa (HR=3.873, 95%CI: 1.676-21.643, P=0.006), T3 stage (HR=1.615, 95%CI: 1.113-1.867, P=0.045), higher N stage (HR=1.768, 95%CI: 1.187-5.654, P=0.019), phase III of TNM stage (HR=2.129, 95%CI: 1.102-3.475, P=0.046), and lymph node metastasis in the No.1/No.8a/No.12a groups (HR=0.451, 95%CI: 0.121-0.552, P=0.035; HR=0.645, 95%CI:0.071-0.886, P=0.032; HR=1.512, 95%CI: 1.381-2.100, P=0.029, respectively). Survival analysis showed that the 5-year RFS of patients in the No.12b positive group was worse than that of those in the No.12b negative group (18.2% vs. 34.5%, P<0.001). Independent predictors of RFS were poorer differentiation of the primary tumor (HR=0.528, 95%CI:0.288-0.969, P=0.039), more severe serous invasion (HR=1.262, 95%CI:1.039-1.534, P=0.019), higher T/N/TNM stage (HR=4.880, 95%CI: 1.909-12.476, P<0.001; HR=2.332, 95%CI: 1.640-3.317, P<0.001; HR=0.139, 95%CI: 0.027-0.713, P=0.018, respectively), and lymph node metastasis in the No.12a/No.12b group(HR=0.698, 95%CI:0.518-0.941, P=0.018; HR=0.341, 95%CI:0.154-0.758,P=0.008, respectively). Conclusion: Detection of micrometastasis can improve the rate of positive lymph nodes. In patients with gastric antrum cancer, dissection of group No.12b lymph nodes may improve the prognosis of those with intraoperative evidence of tumor invasion into the serosa, more than two lymph node metastases, and suspicious lymph nodes in groups No.1 / No.8a / 12a.

Abstract
BACKGROUND Macrophages infiltration and activation play multiple roles in maintaining intestinal homeostasis and participate in the occurrence and development of UC. Thus, the restoration of immune balance can be achieved by targeting macrophage polarization. Previous studies have reported that TXYF could effectively ameliorate DSS-induced colitis. However, the underlying mechanisms of TXYF for DSS-induced colitis are still ill-defined. METHODOLOGY This study was designed to explore the therapeutic effect of TXYF and its regulation in macrophages polarization during DSS-induced mice. In C75BL/6 mice, dextran sulfate sodium (DSS) was used to induce colitis and concomitantly TXYF was taken orally to evaluate its curative effect. In vitro experiment was implemented on BMDMs by lipopolysaccharide, IFN- and ATP. RESULTS Here, we found that TXYF ameliorated clinical features in DSS-induced mice, decreased macrophages M1 polarization but remarkably increased M2 polarization. Mechanically, TXYF treatment effectively inhibited the activities of nuclear transcription factor NF-κB, which further contributed to the decrease of the inflammasome genes of NLRP3, limiting the activation of NLRP3 inflammasome in vivo and in vitro. CONCLUSION Our findings demonstrated administration of TXYF can interfere with macrophage infiltration and polarization to improve the symptoms of acute colitis, by repressing NF-κB/NLRP3 signaling pathway activation. This enriches the mechanism and provides new prospect for TXYF in the treatment of colitis.

Abstract
Objective: To construct a prediction model of pathologic complete response (pCR) in locally advanced rectal cancer patients who received programmed cell death protein-1 (PD-1) antibody and total neoadjuvant chemoradiotherapy by using radiomics based on MR imaging data and to investigate its predictive value. Methods: A clinical diagnostic test study was carried out. Clinicopathalogical and radiological data of 38 patients with middle-low rectal cancer who received PD-1 antibody combined with total neoadjuvant chemoradiotherapy and underwent TME surgery from January 2019 to September 2021 in our hospital were retrospectively collected. Among 38 patients, 23 were males and 15 were females with a median age of 68 (47-79) years and 13 (34.2%) a chieved pCR. These 38 patients were stratified and randomly divided into the training group (n=26) and test group (n=12) for modeling. All the patients underwent rectal MRI before treatment. The clinical, imaging and radiomics features of all the patients were collected, and the clinical feature model and radiomics model were constructed. The receiver operating characteristic (ROC) curves of each model were drawn, and the constructed model was evaluated through the area under the curve (AUC), accuracy, sensitivity, specificity, positive predictive value and negative predictive value. Results: There were no significant differences in age, gender, primary location of tumor and postoperative pathology between the two groups (all P>0.05). Forty-one features were extracted from region of interest in each modality, including 9 first-order features, 24 gray level co-occurrence matrix features and 8 shape features. From 38 patients, 41 features were extracted from each imaging modality of baseline and preoperative DWI and T2WI images, totally 164 features. Only 4 features were preserved after correlation analysis between each pair of features and t-test between pCR and non-pCR subjects. After LASSO cross validation, only the first-order skewness of the baseline DWI image before treatment and the volume in the baseline T2WI image before treatment were retained. The area under the curve, sensitivity, specificity, positive and negative predictive values of the prediction model established by applying these two features in the training group and the test group were 0.856 and 0.844, 77.8% and 100.0%, 88.2% and 75.0%, 77.8% and 66.7%, 88.2% and 100.0%, respectively. The decision curve analysis of the radiomics model showed that the strategy of this model in predicting pCR was better than that in treating all the patients as pCR and that in treating all the patients as non-pCR. Conclusion: The pCR prediction model for rectal cancer patients receiving PD-1 antibody combined with total neoadjuvant radiochemotherapy based on MRI radiomics has the potential to be used in clinical screening or rectal cancer patients who can be spared from radical surgery.

Abstract
PurposeTo investigate the recurrence patterns and prognostic factors of patients with recurrent cervical cancer after radical hysterectomy with node dissection (RHND) followed by adjuvant radiotherapy (RT)/concurrent chemoradiotherapy (CCRT).MethodsThe medical records of 153 patients with pre-operative International Federation of Gynecology and Obstetrics stage IB-IIA cervical cancer, who were treated with RHND followed by adjuvant RT/CCRT at the Liaoning Cancer Hospital between January 1, 2012 and May 31, 2018, were retrospectively analyzed.ResultsThe median disease progression-free survival time was 16 months, and 75.2% (115/153) of patients had a relapse within two years. The survival of patients with multi-site relapse was significantly lower in comparison to those with relapse in a single site (p < 0.001). The survival rate of patients with distant metastasis (DM) and combined recurrence (DM with localregional recurrence [LR]) was significantly lower than that of patients with only LR (p = 0.006, p < 0.001). Furthermore, the survival rate of patients with combined recurrence was significantly lower than that of patients with only DM (p = 0.046). Multivariate analysis showed that resection margin involvement, para-aortic and common iliac lymph node metastasis, DM, no treatment after disease relapse, and early disease relapse were independent prognostic factors associated with poor survival.ConclusionMost of the cervical cancer patients who received initial RHND followed by adjuvant RT/CCRT had a relapse within two years. Resection margin involvement, para-aortic and common iliac lymph node metastasis, DM, no treatment after recurrence, and early disease relapse were found to be prognostic factors in patients with recurrent cervical cancer after RHND followed by adjuvant RT/CCRT.

Abstract
PURPOSE Somatic mutations in the BRAF gene are common in several types of cancer, especially in ovarian serous cancer (OSC). Normally, the BRAF protein is switched on and off in response to signals that control cell growth and development. METHODS To investigate the correlation between the mutation of BRAF gene and the expression of BRAF protein in OSC, pyrosequencing was performed to detect the mutation of the 600th codon in BRAF gene (written as Val600Glu or V600E) in 23 cases of high-grade serous ovarian cancer (HGSC), 28 cases of low-grade serous ovarian cancer (LGSC) and 72 cases of serous borderline ovarian tumors (SBT). Meanwhile, immunohistochemistry which stained with the specific antibody VE1 were used to clarified the expression level of BRAF V600E mutant protein. RESULTS Finally, we found that V600E mutation in LGSC and SBT of occurred in 2 of 23 (7.1%) and 21of 72 (29.2%), respectively. The V600E mutation was not detected in 23 cases of HGSC. One case of HGSC (1, 4.3%), 3 cases of LGSC (3 of 28, 10.7%) and 25 cases of SBT (25 of 72, 34.7%) were positive expression detected by immunohistochemistry. Compared with BRAF gene mutation, the sensitivity, specificity and consistency of BRAF V600E protein were 91.3%, 92% and 91.9%, respectively. CONCLUSION Our findings indicate that BRAF mutations in LGSC and SBT, which are closely related to tumor staging. The specific antibody VE1 could be used as a preliminary screening for the mutation of BRAF gene.

Abstract
Objective: To explore the clinical effects of anterograde sural neurovascular flap in repairing skin and soft tissue defect around the knee. Methods: Nine patients with skin and soft tissue defect around the knee admitted to Beijing Fengtai YouAnMen Hospital from May 2011 to December 2018, were included in this retrospective descriptive study, including 8 males and 1 female, aged 16 to 65 years. The wound area after debridement ranged from 8 cm×5 cm to 18 cm×10 cm. Anterograde sural neurovascular flap was used to repair the wounds in 9 patients, with the area ranging from 9 cm×6 cm to 20 cm×12 cm. The donor sits of flaps in 2 patients were closed and sutured directly, and the donor sits of flaps in 7 patients were repaired with medial split-thickness skin graft of the ipsilateral thigh. The flap survival, complications, and follow-up after operation were recorded. Results: The flaps survived and the blood supply was good in 8 patients and the wounds were closed. One patient developed skin ischemic necrosis which was cured after three weeks of dressing change. All the skin grafts in the donor site of flap in 7 patients survived. In 6 months to 5 years of follow-up after surgery, the skin flap had good texture, color, and shape, and normal sensation. Except for one patient whose knee had poor recovery of function, the knee joint function of the other patients recovered well. Conclusions: The anterograde sural neurovascular flap has the advantages of high survival rate, satisfactory appearance and functional recovery post surgery, and is an ideal flap for repairing the skin and soft tissue defect around the knee.

Abstract
BACKGROUND Endometriosis (EM) is a benign gynecological disease that shares some characteristics with malignancy, such as proliferation and invasion. So far, the pathogenesis of EM is still unclear. In this study, we investigated whether TRIM65 can play a role in the development of EM. METHODS TRIM65 expression levels in eutopic, ectopic, and normal endometrium were detected by quantitative real-time PCR and Western blot. Cell proliferation and invasion of primary endometrial stromal (EMS) cells were detected by CCK-8 and Transwell analysis. The interaction between TRIM65 and DUSP6 or C-myc was measured by coimmunoprecipitation, ubiquitylation, dual luciferase, and chromatin immunoprecipitation analysis. RESULTS We found that TRIM65 was identified as an up-regulated gene in ectopic endometrial tissues and EMS cells compared with control groups without EM. TRIM65 expression was positively correlated with the levels of p-ERK1/2, C-myc, matrix metalloproteinase-2, and integrin β1 in ectopic endometrial tissues in patients and mice. TRIM65 promoted the cell proliferation and invasion of EMS cells via the ERK1/2/C-myc pathway through ubiquitination of DUSP6. C-myc promoted TRIM65 expression through inducing TRIM65 promoter activity. Additionally, the increased expression of TRIM65, C-myc, matrix metalloproteinase-2, integrin β1, and p-ERK1/2 and the decreased expression of DUSP6 in ectopic endometrial tissues were significantly suppressed by inhibition of ERK1/2 signaling pathway in ectopic endometrial tissues in experimental mice model. CONCLUSION In conclusion, TRIM65 promotes invasion of ectopic EMS cells by activating a feedback loop with the ERK1/2/C-myc signaling pathway and may be a potential therapeutic target for EM.

Abstract
Objective: To evaluate the pathologic findings from biopsy samples to predict the status of nodal metastasis for patients with usual cervical adenocarcinoma. Methods: The 32-pair samples of cervical adenocarcinoma specimens (32 cervical biopsies and 32 hysterectomies with staging) from 2013 to 2019 were selected for retrospective study in Shanghai first Maternal and infant Health Care Hospital Affiliated to Tongji University. The correlation between histopathologic features including necrotic tumor debris (NTD), nuclear grade, mitotic count and pattern-based classification system and the status of lymph node metastasis was evaluated. Results: Tumor invasive patterns of cervical adenocarcinoma, as described previously, could be discerned in hysterectomy/staging specimens, but not in cervical biopsies. Because the biopsy tissues were small, only 14(14/32, 43.8%) cases could be classified according to pattern of invasion, and the concordance rate with resected specimens was 37.5%. NTD (9/19) and grade 3 nuclei (11/19) were positively correlated with invasive pattern C and nodal metastases (P<0.05). Moreover, when NTD and (or) nuclear grade were evaluated at the same time, the sensitivity for type C infiltration was higher. Conclusions: Evaluation of NTD and nuclear grade in biopsies for cervical adenocarcinoma provides good predictive value for lymph node metastasis. It is helpful for patient stratification and management andto avoid unnecessary staging procedures. However, multicenter studies and prospective clinical trials are necessary to confirm the findings before clinical application can be considered.

Abstract
OBJECTIVE To obtain the leptin receptor overlapping transcript-like 1 encoding gene (LepROTL1 gene) from Dermatophagoides farina, investigate the molecular characteristics of the gene and construct a prokaryotic expression vector to express this gene. METHODS The LepROTL1 gene-encoding sequence fragments were captured based on the transcriptome sequencing results, and the full-length gene fragments were amplified from total RNA of D. farinae using a RT-PCR assay, and used to construct the expression plasmid pET28a(+)-LepROTL1, followed by sequencing. The plasmid was transformed into E. coli BL21 (DE3) T1R for the induction of IPTG expression. The expression product was characterized by SDS-PAGE and Western blotting. Bioinformatics analyses were performed to analyze the sequence and the molecular characteristics of its encoded protein. RESULTS The amplification products of the RT-PCR assay showed a clear band on agarose gel electrophoresis, and sequencing analysis of the pET28a(+)-LepROTL1 plasmid showed 417 bp in length of the coding gene from the start codon ATG to the termination codon TAA. Following the plasmid transformation into E. coli and induction with IPTG, a specific band was seen on SDS-PAGE, indicating successful expression. Bioinformatics analysis showed that the LepROTL1 gene-encoded protein was composed of 134 amino acids, and had a relative molecular weight of 14 378.13 Da, a hydrophilicity index of 1.149, and certain hydrophobicity. The secondary structure was composed of alpha-helix (19 aa, 14.18%), extended strand (48 aa, 35.82%) and random coil (67 aa, 50.00%). The deduced amino acid sequence was used to obtain homologous genes by BLAST, and the phylogenetic tree showed that D. farinae was clustered with D. pteronyssinus. CONCLUSIONS The full-length sequences and expression plasmid of the LepROTL1 gene are obtained, and the molecular features of the gene are demonstrated using bioinformatics analyses, which provide insights into further studies on the gene.

Abstract
Background To investigate the role of P16 (INK4a)-extracellular signal related kinase 1/2 (ERK1/2) signaling pathway in cisplatin (DDP) resistance induced by multidrug resistance protein 1 (MDR1), also known as P-glycoprotein (P-gp), in cervical adenocarcinoma. Methods A human DDP-resistant HeLa cell line (HeLa/DDP) was constructed using the combination of incremental and intermittent administration of DDP. Cell Counting Kit-8 (CCK-8) assay was used to measure the IC50 and resistance index (RI) of cells. The morphological changes and population doubling time were observed under an inverted microscope. Plate cloning formation assay was performed to evaluate the cell proliferation and tumorigenic ability. Cell invasion and migration were determined by transwell assays. Besides, the expression of P16, phosphorylated extracellular signal related kinase 1 and 2 (pERK1/2), total ERK1/2 and MDR1 were measured using western blot analysis. The ERK-specific inhibitor U0126 and agonist TPA was used to explore the role of ERK. Results The DDP-resistant cervical adenocarcinoma HeLa/DDP cell line was successfully established, which showed stronger cell growth, invasion, and migration. In the HeLa/DDP cells, pERK1/2 was downregulated, P-gp was upregulated and P16 was downregulated. Overexpression of P16 led to a significant decrease in the proliferation rate, migration ability, and invasion ability of the HeLa/DDP cells. Furthermore, overexpression of P16 increased and the decreased expression of pERK1/2 and P-gp in the HeLa/DDP cells, respectively. Treatment of HeLa/DDP cells transfected with P16 plasmid with ERK-specific inhibitor U0126 significantly decreased the expression of pERK1/2 and increased the expression of P-gp from 6 h to 48 h. Moreover, after 72 h, the expression of pERK1/2 was up-regulated and the expression of P-gp was inhibited. Conclusion Overexpression of P16 could partially reverse the MDR1-mediated DDP resistance in the cervical adenocarcinoma by the enhancement of phosphorylation of ERK signaling pathway, which provided a theoretical basis for the treatment of DDP resistance in cervical adenocarcinoma.

Abstract
Objective: To investigate esophageal motility and reflux characteristics in gastroesophageal reflux disease (GERD) with and without extra-esophageal symptoms by high-resolution manometry and 24 h esophageal multichannel intraluminal impedance combined pH (MII-pH) monitoring. Methods: From February 2016 to June 2017, GERD patients with and without extra-esophageal symptoms were enrolled in this prospective controlled study. Esophageal HRM and 24 h MII-pH monitoring were performed. The differences in esophageal motility and reflux parameters were further analyzed between 30 GERD patients with extra-esophageal symptoms and 30 simple GERD patients. Results: The GERD symptom scores didn't show statistical difference between two groups. The GERD symptom scores didn't show statistical difference between two groups. The relaxation pressure of lower esophageal sphincter(LES), the integrated relaxation pressure, and the recovery time of upper esophageal sphincter(UES) of GERD patients with extra-esophageal symptoms were all lower than those of patients without extra-esophageal symptoms [(15±7) vs (21±11)mmHg, (8±3) vs (10±5)mmHg, (388±168) vs (492±170)ms, 1 mmHg=0.133 kPa], and the differences were statistically significant(all P<0.05). The main classification of esophageal motility type of GERD patients with extra-esophageal symptoms was mild esophageal motility disorders (27%, 8/30), and the occurrence of ineffective esophageal motivation was 20% (6/30), which were similar with simple GERD patients. The proximal reflux percentages of weak acid reflux and nonacid reflux, abnormal nonacid reflux in GERD patients with extra-esophageal symptoms were significantly higher than those in simple GERD patients [84.6% (73.2%, 100.0%) vs 75.0% (60.0%, 87.65%), P=0.048; 90.0% (45.8%, 100.0%) vs 0(0, 100.0%), P=0.017; 46.7% vs 3.3%, P=0.03]. Conclusions: The pathogenesis of GERD with extra-esophageal symptoms may be different from typical GERD. Increase of proximal esophageal reflux and abnormal nonacid reflux may all participate in the mechanisms of GERD with extra-esophageal symptoms.

Abstract
One elderly patient with extremely severe burn was admitted to our department on 4th August, 2017. The patient suffered multiple sustained ventricular tachycardia from post injury day 2 to 4 due to relatively high input volume during shock stage. Amiodarone could not be given through intravenous injection because of his low blood pressure. After consultation with cardiologist, ventricular tachycardia was corrected by electrical cardioversion of several times. According to this case, the first treatment is electrical cardioversion when elderly patient with extremely severe burn shows sustained ventricular tachycardia which can not be corrected with medicine.

Abstract
Objective: To investigate the clinical value of endoscopic ultrasonography (EUS) and Multi-slice Spiral CT (MSCT) in the preoperativestaging of tumor(T) and lymph node (N) metastasis in patients with SiewertⅡand Ⅲ typeadenocarcinoma of esophagogastric junction(AEG). Methods: Clinical data of 145 Siewert Ⅱ and Ⅲ type AEG patientswithout preoperative chemoradiotherapy were retrospectively reviewed. Theyall received preoperative EUS and MSCT examination and underwent surgical resection, and the results of EUS and MSCT were compared with their postoperative pathologic staging. Results: The sensitivity, specificity, and accuracy of EUS for T stage in Siewert Ⅱ and Ⅲ type AEG were higher than those of MSCT. The total accuracy of EUS and MSCT were 90.3% and 63.5%, respectively, and the difference was statistically significant (χ(2)=29.52, P<0.01). The sensitivity of EUS for T1, T2 and T3 were 89.5%, 91.1% and 85.2%, respectively, which were significantly higher than 42.1%, 66.7% and 29.6% of MSCT (χ(2)=9.47, P<0.01 for T1; χ(2)=8.07, P<0.01 for T2; χ(2)=17.40, P<0.01 for T3). In addition, the total accuracy of EUS and MSCT for lymph node metastasis status of Siewert Ⅱ and Ⅲ type AEG were 75.9% and 64.8%, respectively, showing a statistically significant difference(χ(2)=4.23, P=0.04). The sensitivity of EUS for N1 and N2 were 82.1% and 79.2%, respectively, which were significantly higher than 53.6% and 60.4% of MSCT (χ(2)=5.24, P=0.02; χ(2)=4.48, P=0.03). There was no statistical significance for sensitivity of EUS and MSCT in N0 and N3 (P>0.05). Conclusion: EUS diagnosis of T and N staging in Siewert Ⅱ/Ⅲ type AEG showed significantly greater performance than MSCT.

Abstract
Objective: To investigate the effect of triptolide, a specific inhibitor of heat shock protein 70 (HSP70), on apatinib resistance in gastric cancer cells line MKN45. Methods: The apatinib-resistant cells (MKN45/AR) and MKN45 parental cells were treated with apatinib, triptolide and apatinib combined with triptolide, respectively. CCK-8 assay was performed to determine the half maximal inhibitory concentration (IC(50)) of MKN45/AR and MKN45 cells in the presence of different treatment. The mRNA expression of heat shock protein gene (HSPA1A and HSPA1B) was detected by RT-PCR, while the protein expression of heat shock protein 70 was analyzed using Western blot in MKN45/AR and MKN45 cells. Results: The IC(50) values of apatinib-sensitive and apatinib-resistant MKN45 cells were 10.411 μmol/L and 70.527 μmol/L, respectively, showing a significant difference (P<0.05). The mRNA expression of HSPA1A and HSPA1B in MKN45/AR cells was significantly higher than that in MKN45 cells (P<0.001). The protein expression of heat shock protein 70 was significantly decreased after 0.25 μmol/L triptolide treatment in MKN45/AR cells (P<0.01). When heat shock protein 70 was inhibited by triptolide, the IC(50) value of apatinib in MKN45/AR cells was reduced to 11.679 μmol/L, which was significantly lower than cells treated with apatinib alone (P<0.05). Conclusions: The apatinib-resistant MKN45 cells have high levels of heat shock protein 70. Low doses of triptolide can significantly inhibit heat shock protein 70, leading to reverse the resistance phenotype of MKN45/AR cells. Therefore, inhibition of heat shock protein 70 provides a new therapy strategy for patients with apatinib resistance.

Abstract
Emerging studies show that dysregulated miRNAs are implicated in tumorigenesis and progression of various cancers. MiRNA-320c, an important member of miRNA-320 family, was characterized as a new candidate miRNA that suppressed the development of colorectal cancer and bladder cancer. However, the function of miRNA-320c in human glioma remained unclear. Here, we found that miRNA-320c was significantly down-regulated in glioma tissues in contrast with normal brain tissues, being tightly related to clinical stage of glioma by qRT-PCR. Moreover, Kaplan-Meier analysis demonstrated that patients with low miRNA-320c expression had a shorter survival. Multivariate Cox regression analysis indicated that miRNA-320c could serve as an independent poor prognostic factor for patients with glioma. Functionally, overexpression of miRNA-320c could dramatically inhibit glioma cell proliferation, migration and invasion, as well as promote apoptosis. Further analysis indicated that overexpression of miRNA-320c dramatically led to the G0/G1 phase arrest and correspondingly decreased the percentage of S phase cells by suppressing the expression of G1/S transition key regulators, such as Cyclin D1 and CDK6. Additionally, up-regulation of miRNA-320c could significantly impair migration and invasion of glioma cells via reducing the expression of MMP2, MMP9, N-cadherin and Integrin β1. Collectively, our data revealed that miRNA-320c played a crucial role in the carcinoma processes of glioma and might serve as a new prognosis biomarker and therapeutic target of glioma.

Abstract
Previous research has focused on revealing the functions of each individual gene and/or pathway in idiopathic dilated cardiomyopathy (DCM) or ischemic cardiomyopathy (IC). However, the common or specific pathways of the initiation and processes of DCM and IC are still unclear. Here, we attempted to uncover the critical genes and potential molecular networks that play important roles in DCM and IC progression commonly or specifically. The transcriptional profiles from normal and DCM or IC patient samples were analyzed and compared using bioinformatic methods. Initially, the normal and DCM or IC sample data were processed and the most notable differentially expressed genes (DEGs) from DCM or IC were identified. By comparing the DEGs from DCM with those from IC, the DCM- and IC-specific DEGs were identified. The gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses indicated the significance of multiple biological processes as well as signaling pathways that affect heart function and DCM or IC progression. Protein-protein interaction network analysis identified the relationships between different genes, and some important genes such as MYC and FN1 were found to be hubs, which master each individual module of DCM-specific and IC-specific DEGs, respectively. We discovered commonalities and differences of gene expression profiles and molecular pathways between different cardiomyopathies. The gene discovery and molecular signature analysis in this study could offer insights into disease mechanisms and also identify markers useful for diagnostic, prognostic, and therapeutic purposes.

Abstract
Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders. The pathogenesis of IBS is not fully clear up to now, but numerous studies suggest that it is related to multiple factors, such as abnormal intestinal motility, visceral hypersensitivity, intestinal infection and immunoreaction, and imbalanced intestinal microbiota. The dysbiosis of the gastrointestinal tract microbiota is considered one of the most important factors responsible for the development of IBS. In this article, we will discuss the relationship between intestinal microbiota and IBS.

Abstract
BACKGROUND/AIMS In this study, a subpopulation of stem-like cells in human high grade serous ovarian carcinomas (ovarian cancer stem cells; OCSCs) were isolated and characterized. METHODS Primary high-grade serous ovarian carcinoma (HGSC) fresh biopsies were cultured under serum-free conditions to produce floating spheres. Sphere formation assay, including self-renewal, differentiation potential, chemo-resistance, and tumorigenicity were determined in vitro or in vivo. RESULTS OCSCs overexpressed stem cell genes (Oct-4, Nanog, Sox-2, Bmi-1, Nestin, CD133, CD44, CD24, ALDH1, CD117, and ABCG2). Immunostaining of spheres showed overexpressed Oct-4, Nanog, and Sox-2. These isolated tumor cells expanded as spheroid colonies for more than 30 passages. In contrast, adherent cells expressed high levels of CA125 and CK7. Flow cytometry analysis showed increased CSC markers (CD44, CD24, CD117, CD133, ABCG2, and ALDH1) in the spheroid cell population. OCSCs displayed higher chemoresistance to cisplatin or paclitaxel compared to adherent cells. Moreover, subcutaneous injection of 1 × 104 sphere-forming cells into NOD/SCID mice gave rise to new tumors similar to the original human tumors and could be passaged in mice. CONCLUSION These results revealed that HGSCs are created and propagated by a small number of undifferentiated tumorigenic cells, and therapeutic targeting of these cells could be beneficial for treatment of HGSCs.

Abstract
This paper studies the stationary probability density function (PDF) of the response of multi-degree-of-freedom nonlinear systems under external independent Poisson white noises. The PDF is governed by the high-dimensional generalized Fokker-Planck-Kolmogorov (FPK) equation. The state-space-split (3S) method is adopted to reduce the high-dimensional generalized FPK equation to a low-dimensional equation. Subsequently, the exponential-polynomial closure (EPC) method is further used to solve the reduced FPK equation for the PDF solution. Two illustrative examples are presented to examine the accuracy of the 3S-EPC solution procedure. One example involves a two-degree-of-freedom coupled nonlinear system. The other example is concerned with a ten-degree-of-freedom system with cubic terms in displacement. A Monte Carlo simulation is also performed for simulating the PDF solution of the response. The comparison with the simulated result shows that the 3S-EPC solution procedure can provide satisfactory PDF solutions. The good agreement is also observed in the tail regions of the PDF solutions.

Abstract
OBJECTIVE To search the difference of the angiogenic activity between T/NK-cell lymphomas and B-cell lymphomas. METHODS The T/NK-cell was stained immunohistochemically by CD56 and CD45 RO, the B-cell was by CD20, the microvessel endothelium was by CD34. Sixty-one cases were studied to examine the immunophenotype and to estimate the intratumoral microvessel density (iMVD). RESULTS Forty in 61 cases (65.6%) expressed the immunophenotype of both T-cell and Natural Killer cell, were diagnosed T/NK-cell lymphomas. Fifteen in 61 cases (24.6%) expressed the immunophenotype of B-cell. There was a significant difference in incidence between the two types of lymphomas (chi 2 = 22.4, P < 0.01). The mean of iMVD/HPF was 24.1 +/- 8.7 in 40 cases of T/NK-cell lymphomas, while the mean of iMVD/HPF was 14.9 +/- 3.8 in 15 cases of B-cell lymphomas. The difference (t = 3.7, P < 0.05) was significant. CONCLUSION The angiogenic activity of T/NK-cell lymphomas is much more than that of B-cell lymphomas. This study shows nasal/nasopharyngeal T/NK-cell lymphomas are with evident angiogenic activity.

Abstract
A general nonlinear structural equation model with mixed continuous and polytomous variables is analysed. A Bayesian approach is proposed to estimate simultaneously the thresholds, the structural parameters and the latent variables. To solve the computational difficulties involved in the posterior analysis, a hybrid Markov chain Monte Carlo method that combines the Gibbs sampler and the Metropolis-Hasting algorithm is implemented to produce the Bayesian solution. Statistical inferences, which involve estimation of parameters and their standard errors, residuals and outliers analyses, and goodness-of-fit statistics for testing the posited model, are discussed. The proposed procedure is illustrated by a simulation study and a real example.

Abstract
The complete nucleotide sequence of the N protein gene of rice yellow stunt rhabdovirus (RYSV) was determined by sequencing of cDNA clones derived from the viral genomic RNA. The 3' end of the N gene (messenger sense) was defined by sequence analysis of cDNA clones generated from the N protein mRNA by 3'RACE. The 5' end sequence of the gene was putatively assigned as 5'-AACAC-3'; this sequence is found in the presumed 3' leader/N gene junction region. The mRNA encoding the RYSV N protein is 1714 nt comprising a 15-nt untranslated 5' leader sequence followed by an open reading frame (ORF) of 1563 nt and a 136-nt untranslated 3' region. The calculated molecular mass of the N protein encoded by the ORF is 58,400 Da, which is larger in size than N proteins of other rhabdoviruses. Amino acid composition analysis shows that the RYSV N protein is rather basic with a predicted isoelectric point of 10.04; indeed, a large highly basic region could be found at the carboxy terminal portion of the protein. Amino acid sequence comparison between N proteins of RYSV and sonchus yellow net virus, both of which belong to the same genus Nucleorhabdovirus, revealed an overall 30% identity, with three relatively conserved blocks of 14-20 amino acid residues. Moreover, the hydropathy profiles of the two proteins are generally similar. The structural similarities between the N protein of RYSV and that of lettuce necrotic yellows virus, the type member of the genus Cytorhabdovirus, and those of animal rhabdoviruses, are less significant. Nucleotide sequence determination of 5' and 3' regions flanking the RYSV N gene identified a 14-nt common sequence that is very similar to the consensus gene junction sequences of other plant and animal rhabdoviruses.
