RESUMO

Objective: To investigate the clinicopathological features and outcome of gastroenteropancreatic high-grade neuroendocrine tumors. Methods: A total of 60 gastroenteropancreatic high-grade neuroendocrine tumors were collected from January 1st, 2013 to December 31th, 2018 at Fudan University Shanghai Cancer Center, with available pathology databases and clinic follow-up information. At the same time, 157 cases of gastrointestinal pancreatic neuroendocrine neoplasm (NEN) diagnosed at the hospital in 2018 were collected and the incidence of NEN at all grades was compared. Results: There were 32 males and 28 females, aged 13-80 years (mean 54 years). Pancreas primary was the most common (48%, 29/60). Nodal metastatic rate was 9/16 and distant metastatic rate was 41%(18/44). Liver was the most common site of metastasis. Among all the gastroenteropancreatic neuroendocrine neoplasms diagnosed in the hospital in 2018, the incidence of high-grade neuroendocrine tumors was the lowest (7%, 11/157). High-grade neuroendocrine tumors had typical pathologic features of well-differentiated/moderate neuroendocrine tumors, but with significant differences in mitotic rates. By immunohistochemical staining, most of the tumors expressed neuroendocrine markers and somatostatin receptor 2 was positive in 60% (12/20) of the cases. The average Ki-67 index was 30%-40%, and there was significant difference between cases (18%-80%). The overall survival of high-grade neuroendocrine tumors was 43 months, and the disease-free survival was 12 months. Conclusions: High-grade neuroendocrine tumor is a rare group of neuroendocrine tumors, with unique clinicopathological features and good prognosis. Pathological classification and grading of gastroenteropancreatic neuroendocrine neoplasms can help clinicians to select appropriate treatment and accurately evaluate prognosis.

RESUMO

By comprehensive structure design and first-principles calculations, we report a novel two-dimensional (2D) BeP nanomaterial with exotic structural and properties. This BeP 2D material is formed by a couple honeycomb sheets by slab staggered stacking and strong interlayer bondings. It behaves as a natural 2D semiconductor with several notable properties: a modest bandgap (~1.34 eV), high room-temperature electron mobility (~104 cm2 V-1 s-1) and high visible-light absorption coefficient (~105 cm-1); Moreover, due to the unique stacking topology, BeP may display distinctive direction-dependent electric transport by the anisotropic polarity of electron and hole mobilities, that is, it exhibits n-type (electron mobility > hole mobility) along the armchair direction while acts as p -type (hole mobility > electron mobility) in the zigzag direction, thus promising for applications in nanoelectronics. The BeP has good dynamic and thermal stabilities and is also the lowest-energy structure of 2D space indicated by particle swarm search, implying the high feasibility of experimental synthesis.

RESUMO

Objective: To investigate the potential risk factors for the death of patients underwent gastric pull-up reconstruction following total pharyngoesophagectomy during perioperative periods. Methods: A total of 71 patients, including 64 males and 7 females, aged from 35 to 72 years old, with hypopharyngeal or cervical esophageal carcinoma, who underwent gastric pull-up reconstruction after pharyngoesophagectomy between October 2008 and October 2017, were reviewed retrospectively. Seventeen factors which may have potential influence on the mortality of patients during perioperative periods were evaluated by single factor Logistic regression analysis, and then those factors with obvious difference in statistics were further analyzed by multi-factor Logistic regression. Results: The rate of perioperative mortality was 9.9% (7/71). Single factor Logistic regression analysis indicated that the age of patients, abnormal electrocardiogram, TNM stages, alanine aminotransferase and D-Dimer changes, postoperative bleeding were risk factors for the death of patients(P values were 0.023, 0.004, 0.026, 0.021, 0.015 and 0.002, respectively). Multi-factor Logistic regression showed that postoperative bleeding and D-Dimer changes were 2 independent risk factors for perioperative death(P=0.021 and 0.047, respectively). Conclusions: Many potential factors may affect the perioperative mortality of patients underwent gastric pull-up reconstruction following total pharyngoesophagectomy. Postoperative bleeding and significantly elevated D-Dimer level were independent risk factors for the death of patients, indicating poor prognosis.

RESUMO

Objective: To investigate the knowledge regarding clinical research among children at 8-18 years of age. The survey results will form the basis for developing public education program for this population. Methods: The survey was conducted among children at 8-18 years of age using WeChat and spot investigation between January 2016 and January 2017. According to different developmental stages, the survey population was divided into four groups: age 8-10, 11-13, 14-15 and 16-18 years. The level of knowledge regarding clinical research was analyzed. Results: Totally 1 329 questionnaires were issued and 1 233 effective questionnaires were returned with a recovery rate of 92.8%. The overall awareness rate regarding clinical research was 32.8% (405/1 233) . It revealed that 282 (22.9%) individuals thought that clinical research was to treat people like experimental rats. When asked "who have the final decision on research participation", the percentages of those who chose oneself, parents or guardian and doctor were 44.6% (550/1 233), 74.2% (915/1 233) and 36.8% (454/1 233) respectively. When asked "If you want to participate a study, but your parents or guardian do not agree, what would you do?", 33.9% (418/1 233) of individuals will "give up". As to "If you do not want to participate a study, but your parents or guardian think you should, what would you do?", 51.3% (632/1 233) chose "listen to parents" and 28.8% (355/1 233) chose "refuse the suggestions of parents or guardian". As to "what are your greatest concerns of participating an investigation?" , 68.1% (840/1 233) chose "worry about added pain or discomfort". but 58.0% (715/1 233) thought if "doctors and nurses take good care of me" their "concerns will reduce" or "feel better to participate in the research?". 55.6% (686/1 233) and 49.3% (608/1 233) individuals responded that they will "participate in an research?" when they "know that other people also participate the research" and when they "know the details regarding what will happen after the enrollment". Conclusions: The knowledge level of clinical research among children aged 8-18 years were not high. It is very necessary to promote the public education of clinical research for this population and also very necessary to address their concern regarding the research.

RESUMO

Objective: To evaluate the accuracy and influencing factors of T-stage restaging of rectal cancer following neoadjuvant therapy with endorectal ultrasonography (ERUS). Methods: In a retrospective study, endorectal ultrasound was performed in 86 patients with rectal cancer following neoadjuvant therapy. The imaging results were compared with postoperative pathological T-stage. Results: The accuracy of overall T-stage restaging with ERUS was 67.4% (58/86). Additionally, the accuracy of restaging in middle and high rectal cancer was higher, with an accuracy of 76.1%(35/46)and 100%(4/4) respectively. Univariate analysis showed that the location of tumors was an independent factor affecting the accuracy of ERUS(P=0.033). Conclusion: ERUS is an effective method to restage T-stage of rectal cancer following neoadjuvant therapy.

RESUMO

At the present day, curettage and periodontal surgery comprise the main strategy for the treatment of periodontitis, however, these methods are limited in regenerating cementum. It has been found that some biological factors such asenamel matrix derivative (EMD), transforming growth factor-ß (TGF-ß) and insulin-like growth factor (IGF) could promote cementum regeneration. In the cementum regenerationstudies, there has been a lack of criteria to distinguish cementum from alveolar bone and other types of cementum. Therefore, this article will briefly review the biological factors that affect the cementum regeneration and the molecular markers used to judge the regenerating cementum.

RESUMO

The research of new superconductors is an ongoing field for the fundamental significances and potential applications, and two-dimensional (2D) nanomaterials open a new alluring branch for exploration. Here we predict by first-principles calculations that 2D pristine graphene-like BSi monolayer is a phonon-mediated superconductor above the boiling point of liquid helium. The intrinsic covalent-metallic ground state, large density of states at Fermi energy, proper electronic organization as well as strong coupling of out-of-plane phonons and electrons endow an intermediate electron-phonon coupling of ~1.12, rendering this honeycomb sheet as a conventional superconductor with a relatively high T c ~ 11 K. As the global minimum structure in the 2D space previously predicted, this superconducting BSi monolayer may be feasible experimentally. Our finding provides a new field of superconducting nanomaterials for study.

RESUMO

In order to elucidate pressure-induced second superconducting phase (SC-II) in A x Fe2-ySe2 (A = K, Rb, Cs, and Tl) having an intrinsic phase separation, we perform a detailed high-pressure magnetotransport study on the isoelectronic, phase-pure (Li1-xFe x )OHFe1-ySe single crystals. Here we show that its ambient-pressure superconducting phase (SC-I) with a critical temperature Tc ≈ 40 K is suppressed gradually to below 2 K and an SC-II phase emerges above Pc ≈ 5 GPa with Tc increasing progressively to above 50 K up to 12.5 GPa. Our high-precision resistivity data uncover a sharp transition of the normal state from Fermi liquid for SC-I to non-Fermi liquid for SC-II phase. In addition, the reemergence of high-Tc SC-II is found to accompany with a concurrent enhancement of electron carrier density. Without structural transition below 10 GPa, the observed SC-II with enhanced carrier density should be ascribed to an electronic origin presumably associated with pressure-induced Fermi surface reconstruction.

RESUMO

Inhalation injury from exposure to fire smoke is one of the causes of burn-related death. In this study, a realistic three-dimensional human upper airway model was built from magnetic resonance imaging (MRI) scanned images, including the nasal, oral, pharynx, larynx, trachea and part of the first generation of the tracheobronchial tree, as well as a tissue region from the pharynx to the upper bronchi. The Transition Shear Stress Transport (SST-transition) turbulence model, Pennes bioheat transfer equation, convective boundary conditions and a Lagrangian frame were applied and verified with experimental measurements to simulate the airflow fields, temperature distributions and particle deposition in the human airway model. The effects of flow rate, inhalation temperature and particle diameter were studied. It showed that the oral cavity is more likely to be affected by the inlet air conditions. The mucosa in the oral, pharynx and larynx are more likely to cause the thermal injury. The inspiration flow rate significantly influences the airflow fields, temperature distributions and particle deposition fraction interior of the human upper airway model, especially in the pharynx-larynx region. The rising flow rate, inhalation air temperature and particle diameter all contribute to boosting the total deposition fraction in the model. The heated particles with a higher temperature are more likely to be deposited in the oral cavity and the influence of the inlet temperature has a minor influence in the case of a bigger particle diameter.

RESUMO

Objective: To investigate the value of secondary cervical lymph node dissection in papillary thyroid carcinoma (PTC). Methods: PTC patients with recurrence re-operated in a previously dissected area at our hospital during 2000-2016 were included in this analysis. Patients were divided according to the operative interval of 6 months. The level and number of lymph node metastasis and the number of lymph node dissection were analyzed to calculate the ratio of lymph node metastasis. Results: A total of 336 PTC patients received 360 side lateral cervical lymph nodes dissection. The ratio of recurrence in unilateral lateral neck is 92.9%(312/336). The ratio of recurrence in multiple levels (more than two regions) were 47.5% (171/360). The recurrence ratio of level Ⅱ, Ⅲ, Ⅳ and Ⅴ were 55.6%(200/360), 44.2%(159/360), 59.7%(215/360) and 10.3%(37/360), respectively. Lymph node metastases were inclined to level Ⅱ (33.6%) and Ⅳ (35.8%). The mean number of lymph node dissection and metastasis in the group of operative interval ≤ 6 months was 26.56 per case and 4.37 per case, respectively. The mean number of lymph node dissection and metastasis in the group of operative interval >6 months was 16.80 per case and 3.20 per case, respectively. The number of lymph node dissection and metastasis between these two groups were significantly different (P=0.001, P<0.001). Conclusions: Lymph node metastasis of PTC patients with secondary cervical lymph node dissection are inclined to level Ⅱ and level Ⅳ. Moreover, multi-level metastasis is not rare. Level Ⅱ and level Ⅳ require more attention in the first operation. Most of the patients undergo reoperation because of residual lymph nodes from the previous treatment. Normalization and completeness of the initial dissection are particularly important to PTC patients.

RESUMO

OBJECTIVE: To determine if insemination site or pre-ovulatory follicle diameter at fixed-time artificial insemination (FTAI) affects the odds of pregnancy when heifers are inseminated with sexed semen. METHODS: The study was conducted in 422 Holstein heifers enrolled into 531 inseminations. Inseminations were randomly allocated to 1 of 16 treatment combinations involving three variables: semen type (sexed vs non-sexed), insemination site (uterine horn vs uterine body) and one of four sires. Ovaries were examined by transrectal ultrasound prior to FTAI to determine the follicle diameter and location. AI technician, times bred, age, weight and temperature-humidity index were also recorded. Pregnancy diagnosis was conducted 29 days post-insemination. Follicle diameter and body weight were categorised according to arbitrary cut-points. Each variable was analysed by logistic regression to determine the effect on pregnancy per AI and compare between sexed and non-sexed inseminations. RESULTS: Insemination site did not affect pregnancy per AI for either sexed (P = 0.528) or non-sexed (P = 0.886) inseminations. Heifers with an 18-22 mm follicle had better odds of pregnancy than heifers that did not (odds ratio (OR) 1.45, 95% confidence interval (CI) 1.004-2.09), although no effect was detected for only sexed or only non-sexed inseminations. Heifers weighing 310-370 kg had a higher pregnancy per AI than heifers weighing > 370 kg for non-sexed inseminations (P = 0.004) and sexed semen from sire 4 caused lower odds of pregnancy than semen from sire 1 (OR 0.40, 95% CI 0.18-0.89). CONCLUSION: Insemination site did not affect pregnancy per AI, but heifers with an 18-22 mm pre-ovulatory follicle at insemination had better odds of pregnancy for both sexed and non-sexed inseminations.

RESUMO

Redspotted grouper nervous necrosis virus (RGNNV) is one of the most devastating pathogens in the aquaculture of the grouper, Epinephlus sp., worldwide. The early and rapid diagnosis of RGNNV is important for the prevention of RGNNV infection. In this study, an aptamer (A10)-based sandwich enzyme-linked apta-sorbent assay (ELASA) was developed for RGNNV diagnosis. This sandwich ELASA showed high specificity for the RGNNV coat protein (CP) and virions in virus-infected cells and tissues. At the optimized working concentration of 200 nM of aptamer, the ELASA could detect RGNNV in the lysates of as few as 4 × 103 RGNNV-infected GB cells. Incubation for 10 min was sufficient to produce accurate results. The sandwich ELASA was most stable at incubation temperatures of 4-25°C, but could still distinguish RGNNV-infected samples from the controls at 37°C. It could detect RGNNV infection in brain lysates diluted 1/10, with results consistent with those of reverse transcription PCR, although with 10% less sensitivity. The main equipment required includes dissection tools, a water bath, Pierce™ Streptavidin Coated Plates and a microplate reader. The sandwich ELASA has great potential utility for the rapid and sensitive diagnosis of RGNNV in its early stages by fish farmers.

RESUMO

Maternal depressive symptoms influence neurodevelopment in the offspring. Such effects may appear to be gender-dependent. The present study examined contributions of prenatal and postnatal maternal depressive symptoms to the volume and microstructure of the amygdala in 4.5-year-old boys and girls. Prenatal maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) at 26 weeks of gestation. Postnatal maternal depression was assessed at 3 months using the EPDS and at 1, 2, 3 and 4.5 years using the Beck's Depression Inventory-II. Structural magnetic resonance imaging and diffusion tensor imaging were performed with 4.5-year-old children to extract the volume and fractional anisotropy (FA) values of the amygdala. Our results showed that greater prenatal maternal depressive symptoms were associated with larger right amygdala volume in girls, but not in boys. Increased postnatal maternal depressive symptoms were associated with higher right amygdala FA in the overall sample and girls, but not in boys. These results support the role of variation in right amygdala structure in transmission of maternal depression to the offspring, particularly to girls. The differential effects of prenatal and postnatal maternal depressive symptoms on the volume and FA of the right amygdala suggest the importance of the timing of exposure to maternal depressive symptoms in brain development of girls. This further underscores the need for intervention targeting both prenatal and postnatal maternal depression to girls in preventing adverse child outcomes.

RESUMO

A cell line derived from the head kidney of golden pompano Trachinotus ovatus (TOHK) was established and characterized in this study. The TOHK cells grew most rapidly at 28° C and the optimum foetal bovine serum concentration in L-15 medium was 10%. The TOHK cells have a diploid chromosome number of 2N = 54. The transfection efficiency of TOHK cells was 7·5% at the 15th passage and 72% at the 40th passage. The transfection efficiency in TOHK cells was high, so these cells are suitable for foreign gene expression. The cytotoxic effects of heavy metals and extracellular products from Vibrio anguillarum and Vibrio alginolyticus were demonstrated in TOHK cells, so this TOHK cell line could also be applied in environmental monitoring of heavy metals and pathogenic bacteria. TOHK cell line showed high virus susceptibility, such as grouper nervous necrosis virus (GNNV) and Singapore grouper iridovirus (SGIV). Then, TOHK cell line could be used for the study of viral pathogenesis and the development of antiviral strategies.

RESUMO

OBJECTIVE: To determine the effects of ovarian structures present at Ovsynch™ enrolment, disease history, lactation variables and times bred on pregnancy per fixed-time artificial insemination (FTAI) following fixed-time insemination after Ovsynch and to determine the relationship between the size of ovarian follicular structures and concurrent presence of a corpus luteum (CL). METHODS: The study was conducted in a 3000-cow Holstein dairy herd. Over a 6-month period, 886 non-pregnant cows were examined by transrectal ultrasound and enrolled into 1132 Ovsynch events. Enrolled cows were synchronised using an Ovsynch-56 protocol. At enrolment, both ovaries were scanned by transrectal ultrasound to identify and record the presence and size of ovarian structures. Cows that did not return to oestrus were pregnancy tested 32-38 days post-insemination. Univariable and multivariable generalised linear mixed models (GLMMs) were used to determine the effect of each variable on pregnancy per FTAI. A univariable GLMM was also used to analyse the relationship between size of the dominant follicular structure and concurrent presence of a CL. RESULTS: CL size (P = 0.039) and presence of a luteal cyst (P = 0.002) at Ovsynch enrolment significantly increased the odds of pregnancy. Occurrence of lameness (P = 0.035) or mastitis (P = 0.008) between calving and enrolment significantly decreased the odds of pregnancy. Neither the presence nor size of a follicular structure significantly affected the odds of pregnancy, although cows with larger follicular structures were less likely to have a concurrent CL (P < 0.001). CONCLUSION: Presence of luteal tissue at Ovsynch enrolment and recent disease events affected pregnancy per FTAI in cows inseminated after Ovsynch.

RESUMO

FEAT protein is uniformly overexpressed in a variety of human cancers but weakly expressed in normal tissue. FEAT has antiapoptotic activity and plays a role in carcinogenesis; however, the correlation between FEAT and clinicopathologic characteristics in cancer has not been reported. Our study explores the expression of FEAT protein and its clinicopathologic significance in breast cancer. We examined the expression of FEAT in tissues from 131 cases of breast cancer by immunohistochemistry and analyzed the correlation between FEAT expression and clinicopathologic parameters. The difference in FEAT expression between normal breast tissues and breast cancer tissues was also investigated. Finally, we analyzed the association between FEAT expression and disease-free survival or overall survival. Our data showed that FEAT was expressed in the cytoplasm. The expression of FEAT protein was significantly higher in breast cancer tissues than in normal breast tissues. Moreover, the expression of FEAT protein was higher in breast cancer with a larger tumor size (>2 cm), negative PR, positive HER2, or higher Ki67 index (≥14%) than in breast cancer with a smaller tumor size (≤2 cm), positive PR, negative HER2, or lower Ki67 index (<14%) (P<0.05). In addition, the expression of FEAT protein was associated with tumor size, PR status, HER2 expression, Ki67 index, and molecular subtype. Survival analysis showed that disease-free survival and overall survival were significantly shorter in breast cancer patients with high FEAT expression than in those with low expression of FEAT (P<0.05). COX regression analysis showed that FEAT was an independent prognostic factor for recurrence in breast cancer, but not for survival. In conclusion, FEAT may be a potential biomarker for recurrence of breast cancer.

RESUMO

OBJECTIVE: RNA-seq data of rectal adenocarcinoma (READ) were analyzed with bioinformatics tools to unveil potential biomarkers in the disease. MATERIALS AND METHODS: RNA-seq data of READ were downloaded from The Cancer Genome Atlas (TCGA) database. Differential analysis was performed with package edgeR. False discovery rate (FDR) < 0.05 and |log2 (fold change)|>1 were set as cut-off values to screen out differentially expressed genes (DEGs). Gene coexpression network was constructed with package Ebcoexpress. Gene Ontology enrichment analysis was performed for the DEGs in the gene coexpression network with DAVID online tool. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis was also performed for the genes with KOBASS 2.0. RESULTS: A total of 620 DEGs, 389 up-regulated genes, and 231 down-regulated genes, were identified from 163 READ samples and 9 normal controls. A gene coexpression network consisting of 71 DEGs and 253 edges were constructed. Genes were associated with ribosome and focal adhesion functions. Three modules were identified, in which genes were involved in muscle contraction, negative regulation of glial cell proliferation and extracellular matrix organization functions, respectively. Several critical hub genes were disclosed, such as RPS2, MMP1, MMP11 and FAM83H. Thirteen relevant small molecule drugs were identified, such as scriptaid and spaglumic acid. A total of 8 TFs and 5 miRNAs were acquired, such as MYC, NFY, STAT5A, miR-29, miR-200 and miR-19. CONCLUSIONS: Several critical genes and relevant drugs, TFs and miRNAs were revealed in READ. These findings could advance the understanding about the disease and benefit therapy development.

RESUMO

BACKGROUND: Migrant children refer to rural children who accompany one or both parents to urban area. Empirical evidence showed that compared with their urban counterparts, migrant children had poorer developmental, emotional and psychological health. METHOD: A sample of 1306 migrant children were recruited to examine the characteristics of migrant children and investigate the effects of identity integration, support and socioeconomic factors (e.g. age, gender, type of school, family socioeconomic status, city type) on their subjective wellbeing. RESULTS: Children with higher levels of identity integration, social support, family socioeconomic status, who attended public school and who lived in the third-tiered city of Weihai demonstrated better subjective wellbeing. Social support remained a strong predictor for subjective wellbeing, despite a significant mediating effect of identity integration. CONCLUSIONS: These results highlight the need for policymakers and practitioners alike to address individual factors pertaining to psychological adjustments, as well as social determinants of subjective wellbeing in the context of migration.

RESUMO

OBJECTIVE: To investigate the survival status of patients with pharyngeal, laryngeal or cervical esophageal cancers, who received free jejunal flap (FJF) to repair the defects following tumor resection, and to analyze the effect of multi-disciplinary treatment on their survival. METHODS: Fifty-eight patients with pharyngeal, laryngeal or cervical esophageal cancer underwent free jejunal flap (FJF) reconstruction after cancer resection between 2010 and 2013. All their clinical records were reviewed and analyzed. RESULTS: The success rate of flap transplantation was 91.4% (53/58). The 2-year overall survival rates (OSR) of cervical esophageal cancer and hypopharyngeal cancer patients were 67.5% and 49.3%, respectively, both were significantly better than that of laryngeal cancer. The main causes of death were local recurrence and distant metastases. The group with no short-term complications had a better two-year OSR (59.0%) than the group with short-term complications (46.6%), however, the difference between them was not significant (P=0.103). The 2-year survival rate of the initial treatment group was 65.0%, better than that of the salvage treatment group (49.4%), but the difference was not significant (P=0.051). For the stage III and IV patients, the multi-disciplinary treatment group had a significantly better 2-year OSR (64.7%) than the single or sequential treatment group (37.0%, P=0.016). CONCLUSIONS: Free jejunal flap reconstruction is an ideal option for repairing the cervical digestive tract circumferential defects caused by tumor resection with a high success rate and a low mortality. Compared with the single or sequential treatment, multi-disciplinary treatment can significantly improve the survival rate of late-stage hypopharyngeal and cervical esophageal cancer patients.

RESUMO

Gastric cancer (GC) is the leading malignancy in the digestive system. Versican is a ubiquitous component of the extracellular matrix and has a role in tumor progression. We aim to examine the expression of Versican in GC and the relationship between Versican levels and patient survival. We detected the mRNA expression of Versican in tumorous pairs and adjacent normal tissues (ANTs) of 78 GC patients by quantitative real-time polymerase chain reaction. The protein expression of Versican in 101 cases of matched GC and ANT, as well as in 27 intraepithelial neoplastic (IN) samples, was evaluated by immunohistochemistry. We analyzed the correlation between Versican levels and clinical outcomes. Finally, we performed CCK-8 cell counting assay and transwell assay in GC cell lines. Versican mRNA expression was significantly greater in tumor tissues (P<0.001) than in ANT. Versican was majorly expressed in the stroma surrounding tumor epithelium and minorly some areas of tumor epithelium. The Versican expression level was higher in GC than in ANT (P=0.004), but no significant difference was observed between ANT and IN (P=0.517). The Versican mRNA and protein levels were consistent in GC. High Versican mRNA and protein expression correlated with greater tumor invasion depth (P=0.030, P=0.027). Univariate and multivariate analysis revealed that patients with high Versican mRNA expression exhibited poor disease-specific survival (P<0.001). In vitro experiments showed that Versican overexpression promoted cell proliferation and invasion. Our data indicate that Versican may be a novel prognostic indicator in GC and may be a potential target for clinical diagnosis.
