OBJECTIVETo summarize the treatment status of gastric gastrointestinal stromal tumor (GIST) in Shandong province,by analyzing the clinicopathological features and prognostic factors.

METHODSClinicopathological and follow-up data of 1 165 patients with gastric GIST between January 2000 and December 2013 from 23 tertiary referral hospitals in Shandong Province were collected to establish a database. The risk stratification of all cases was performed according to the National Institutes of Health(NIH) criteria proposed in 2008. Kaplan-Meier method was used to calculate the survival rate. Log-rank test and Cox regression model were used for univariate and multivariate prognostic analyses.

RESULTSAmong 1 165 cases of gastric GIST, 557 were male and 608 were female. The median age of onset was 60 (range 15-89) years. Primary tumors were located in the gastric fundus and cardia in 623 cases(53.5%), gastric body in 346 cases(29.7%), gastric antrum in 196 cases(16.8%). All the cases underwent resection of tumors, including endoscopic resection (n=106), local resection (n=589), subtotal gastrectomy(n=399), and total gastrectomy(n=72). Based on the NIH risk stratification, there were 256 cases (22.0%) at very low risk, 435 (37.3%) at low risk, 251 cases (21.5%) at intermediate risk, and 223 cases (19.1%) at high risk. A total of 1 116 cases(95.8%) were followed up and the median follow-up period was 40 (range, 1-60) months. During the period, 337 patients relapsed and the median time to recurrence was 34 (range 1-60) months. The 1-, 3-, and 5-year survival rates were 98.6%, 86.1% and 73.4%, respectively. The 5-year survival rates of patients at very low, low, intermediate, and high risk were 93.1%, 85.8%, 63.0% and 42.3% respectively, with a statistically significant difference (P=0.000). Multivariate analysis showed that primary tumor site (RR=0.580, 95%CI:0.402-0.835), tumor size (RR=0.450, 95%CI:0.266-0.760), intraoperative tumor rupture(RR=0.557, 95%CI:0.336-0.924), risk classification (RR=0.309, 95%CI:0.164-0.580) and the use of imatinib after surgery (RR=1.993, 95%CI:1.350-2.922) were independent prognostic factors.

CONCLUSIONSThe choice of surgical procedure for gastric GIST patients should be based on tumor size. All the routine procedures including endoscopic resection, local excision, subtotal gastrectomy and total gastrectomy can obtain satisfactory curative outcomes. NIH classification has a high value for the prediction of prognosis. Primary tumor site, tumor size, intraoperative tumor rupture, risk stratification and postoperative use of imatinib are independent prognostic factors in gastric GIST patients.

Objective To investigate the expression changes of miR-335 in rats with focal cerebral ischemia and their mechanisms. Methods Fifty adult healthy male SD rats were randomly divided into sham-operated group, model group, miR-335 transfection group, negative control group and blank plasmid group (n=10). The focal cerebral ischemia rat models in the later 4 groups were constructed by Longa method. After model making, rats in the miR-335 transfection group were injected recombinant plasmid pcDNA3.1-miR-335 and stearamide (SA) liposome mixture into the lateral ventricle, rats in the negative control group were injected pcDNA3.1-negative control and SA liposome mixture into the lateral ventricle, rats in the blank plasmid group were injected pcDNA3.1(+) and SA liposome mixture into the lateral ventricle, and rats in the sham-operated group and model group were injected the same volume of saline. Twenty-four h after ischemia, the neurological deficit of these rats were assessed by Zea-Longa scale. These rats were sacrificed, and the brain infarct volumes were measured by TTC staining; the miR-335 expression in cerebral ischemia tissues of rats was detected by using real-time fluorescence quantification PCR (RTFQ PCR); the protein expressions of cell adhesion molecule 1 (CD31) and vascular endothelial growth factor (VEGF) in cerebral ischemia tissues of rats were detected by Western blotting. Results As compared with those in the sham-operated group, the neurological function scale scores and brain infarct volumes of rats in model group, miR-335 transfection group, negative control group and blank plasmid group were significantly increased (P<0.05); the neurological function scale scores and brain infarct volumes of rats in miR-335 transfection group were significantly decreased as compared with those in the model group (P<0.05). As compared with those in the sham-operated group, the relative miR-335 expression level in the cerebral ischemia tissues of the model group, miR-335 transfection group, negative control group and blank plasmid group were statistically decreased (P<0.05); miR-335 transfection group had significantly increased relative miR-335 expression level as compared with the model group (P<0.05). As compared with those in the sham-operated group, the CD31 and VEGF protein relative expression levels in the cerebral ischemia tissues of the model group, miR-335 transfection group, negative control group and blank plasmid group were significantly decreased (P<0.05); as compared with those in the model group, the CD31 and VEGF protein relative expression levels in the miR-335 transfection group were statistically increased (P<0.05). Conclusion Up-regulation of miR-335 expression might improve cerebral ischemic tissue injury; it might be related to promote the angiogenesis in cerebral ischemia tissues.

PURPOSE: The importance of long noncoding RNAs (lncRNAs) in tumorigenesis has recently been demonstrated. However, the role of lncRNAs in development of thyroid cancer remains largely unknown. MATERIALS AND METHODS: Using quantitative reverse transcription polymerase chain reaction, expression of three lncRNAs, including BRAF-activated long noncoding RNA (BANCR), papillary thyroid cancer susceptibility candidate 3 (PTCSC3), and noncoding RNA associated with mitogen-activated protein kinase pathway and growth arrest (NAMA), was investigated in the current study. RESULTS: Of the three lncRNAs (BANCR, PTCSC3, and NAMA), expression of BANCR was significantly up-regulated while PTCSC3 and NAMA were significantly down-regulated in papillary thyroid carcinoma (PTC) compared to that in normal tissue. BANCR-knockdown in a PTC-derived cell line (IHH-4) resulted in significant suppression of thyroid stimulating hormone receptor (TSHR). BANCR-knockdown also led to inhibition of cell growth and cell cycle arrest at G0/G1 phase through down-regulation of cyclin D1. In addition, BANCR was enriched by polycomb enhancer of zeste homolog 2 (EZH2), and silencing BANCR led to decreased chromatin recruitment of EZH2, which resulted significantly reduced expression of TSHR. CONCLUSION: These findings indicate that BANCR may contribute to the tumorigenesis of PTC through regulation of cyclin D1 and TSHR.

Objective To develop a dual real-time fluorescent RT-PCR method for rapid detection of enterovirus(EV)and en terovirus type 71(EV71).Methods Specific primers and probes were designed and the dual real-time fluorescent RT-PCR reaction system was established.The quantitative standard curve was drawn;its sensitivity and precision were evaluated.Feces and throat swab specimens of 109 clinical patients with hand foot and mouth disease were collected and tested by using this method.Then the obtained results were compared with those detected by commercial EV71 PCR kit.Results The relative coefficient(2)of EV and EV71 standard curve established by the dual real-time fluorescent RT-PCR method were both 0.998.Its sensitivity reached 0.5 TCID50/mL for detecting EV and 0.05 TCID50/mL for detecting EV71.The within-run precision for detecting EV and EV71 was ＜3％ and total precision≤4％.The results showed good specificity for the detection of enterovirus and non-enterovirus.In 109 detected clinical samples,84 cases of EV positive samples were detected,in which 56 cases were EV71 positive with the total positive rate of 51.4 ％,which was consistent with the result of simple fluorescent RT-PCR commercialization kit(P=1.000).Conclusion The established dual real-time fluorescent RT-PCR method has high sensitivity and good stability,which has an important significance for early high throughput rapid diagnosis of hand foot and mouth disease.
