| 1 | Expression,deleton and mnutation of ρ16 gene in human gastric cancer显示文摘AIM To investigate the relationship between the expression of p16 gene and the gastric carcinogenesis,depth of invasion and lymph node metastases, and to evaluate the deletion and mutation of exon 2 in p16 gene in gastric carcinoma.METHODS The expression of P16 protein was examined by streptavidin-peroxidase conjugated method (S-P); the deletion and mutation of p16 gene were respectively examined by polymerase chain reaction (PCR) and polymerase chain reaction single-strand conformation polymorphism analysis (PCR-SSCP) in gastric carcinoma.RESULTS Expression of P16 protein was detected in 96.25% (77/80) of the normal gastric mucosa, in 92.00% (45/50) of the dysplastic gastric mucosa and in 47.54% (58/122) of the gastric carcinoma. The positive rate of P16 protein expression in gastric carcinoma was significantly lower than that in normal gastric mucosa and dysplastic gastric mucosa (P<0.05). The positive rate of P16 protein expression in mucoid carcinoma 10.00% (1/ 10) was significantly lower than that in poorly differentiated carcinoma 51.22% ( 21/ 41 ),undifferentiated carcinoma 57.69% (15/26) and signet ring cell carcinoma 62.50% (10/ 16) (P<0.05). The positive rate of p16 protein in 30 cases paired primary and lymph node metastatic gastric carcinoma: There was 46.67% (14/30) in primary gastric carcinoma, 16.67% (5/30) in lymph node metastatic gastric carcinoma. The positive rate of lymph node metastatic carcinoma was significantly lower than that of primary carcinoma (P<0.05). There was of p16 gene mutation in exon 2, but 5 cases displayed deletion of p16 gene in exon 2 in the 25 primary gastric carcinomas.CONCLUSIONS The expression loss of P16 protein related to the gastric carcinogenesis, gastric carcinoma histopathological subtypes and lymph metastasis. The mutation of p16 gene in exon 2 may not be involved in gastric carcinogenesis. But the deletion of p16 gene in exon 2 may be involved in gastric carcinogenesis. | Xiu-Sheng He Qi Su Zhu-Chu Chen Xiu-Tao He Zhi-Feng Long Hui Ling Liang-Run Zhang Oncology Institute,Nanhua University,Hengyang 421001,Hunan Province,ChinaOncology Institute,Center South University,Changsha 410078,Hunan Province,China Department of Gastroenterology,First People’s Hospital of Changde City,Changde 415003,Hunan Province,China | 2001 | World Journal of Gastroenterology2001，7，4： | 40 |

| 5 | An Sm-Nd isotopic dating study of the Archean Kongling Complex in the Huangling area of the Yangtze Craton显示文摘Sm Nd isotopic compositions of associated amphibolites, TTG gneisses and granitic gneisses from the Archean Kongling Complex of the Yangtze Craton, South China are systematically analyzed. The results show that the amphibolites and TTG gneisses have a similar age of ca. 2 700 Ma, which well agrees with zircon U Pb dating of previous studies. However, their ε Nd ( t ) are different, suggestive of possible dissimilarity in source composition. | Ling, WL Gao, S Zheng, HF Zhou, L Zhao, ZB | 1998 | Chinese Science Bulletin1998，43，14： | 13 |

| 8 | Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. | Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee | 2014 | World Journal of Clinical Oncology2014，5，2： | 5 |

| 10 | 云南省农村地区男男性接触者与HIV相关的风险行为显示文摘目的探讨中国农村地区男男性接触者(MSM)与艾滋病病毒(HIV)相关的风险行为的具体特点和问题。方法采用半结构化深度访谈的方式进行定性研究。通过一个当地的MSM联系网络,以滚雪球和相互转告的方式招集了24名访谈对象。主要测量指标是与HIV有关的风险行为的上升情况。结果在中国农村地区,风险行为、社会歧视、独生子女政策以及传统中医的观念,在HIV的传播中都起着重要的作用。在中国,许多MSM过着双重生活;调查显示,安全套的使用情况也是因人而异,使风险行为'合理化'的意图是决定是否使用安全套的主要因素;就泌尿生殖系统的问题主动寻求医疗帮助的现象很不普遍,而现有卫生系统以及医务人员对此问题表现出来的不敏感,也进一步加剧了这种现象。结论在资源匮乏的农村地区,MSM人群存在着HIV流行的趋势,并有向普通人群传播的危险。 | 张建波 黄志威 T S K Kong D C Y Ling | 2007 | 中国艾滋病性病2007，13，5： | 3 |

| 12 | Thrombospondin peptide ABT-898 inhibits inflammation and angiogenesis in a colitis model显示文摘AIM: To evaluate the efficacy of the improvedthrombospondin mimetic peptide ABT-898 in a murine model of ulcerative colitis. METHODS: The dextran sodium sulfate(DSS) was used for the induction of colitis in both TSP-1 deficient(TSP-1-/-) and wild type(WT) mice during 7 d. While mice were receiving the DSS dissolved in the drinking water, the ABT-898 peptide was dissolved in sterile 5% glucose solution and delivered using mini pumps subcutaneously implanted. Plasma samples were analyzed for interleukin(IL)-6 by ELISA assay and colonic tissues were harvested, fixed and processed for histological evaluation. Immunohistochemistry using antibodies for the detection of CD31 and MECA in endothelial cells was performed. Inflammation was graded in colonic sections and the number of microvessels in each lesion was assessed. Activation of signal transducer and activator of transcription 3(STAT3) in colonic samples was quantified by immunohistochemistry and Western blotting using antibodies against total STAT3 and phosphorylated STAT3(p STAT3)(Ser727).RESULTS: Treatment with ABT-898 considerably diminished the inflammatory response in WT and TSP-1-/- mice(P < 0.0001 in both groups vs control). Identification of blood vessels highlighted by CD31/MECA immunohistochemistry, showed significantly reduced vessel counts in colitic lesions of WT and TSP-1-/- mice treated with ABT898(TSP-1-/- controls/TSP-1-/- treated, P = 0.0002; WT controls/WT treated, P = 0.0005). Consistently, IL-6 was significantly diminished in plasma samples of TSP-1-/- and WT treated with the peptide when compared to the control mice(P = 0.0002 and P = 0.0148, respectively). p STAT3 positive cells were quantified in WT and TSP-1-/- treated with ABT-898. A significant decrease in positive cells for p STAT3 was observed in treated mice(TSP-1-/- controls/TSP-1-/- treated, P = 0.0089; WT/WT treated, P = 0.0110). These results were confirmedby Western blotting analyses showing lower levels of p STAT3 in colitic lesions from mice treated with the peptide ABT-898.CONCLUSION: These findings indicate that the new peptide ABT-898 ameliorates inflammation and angiogenesis and might be a therapeutic alternative in IBD and inflammatory diseases. | Linda S Gutierrez Jun Ling Derek Nye Konstantina Papathomas Catherine Dickinson | 2015 | World Journal of Gastroenterology2015，21，20： | 2 |
