| 2 | 激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。 | Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 | 2015 | 矿物岩石地球化学通报2015,34,4: | 114 |

| 7 | 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 |
| 8 | The vegetation and climate change during Neocene and Early Quaternary in Jiuxi Basin, China显示文摘Sporopollen record in the Laojunmiao Section at Yumen in the Hexi Corridor foreland depression at the northern margin of the Tibetan Plateau revealed that during the period of 13.0―11.15 Ma the ecological environment of the Jiuxi Basin is characterized by steppe vegetation and a semi-moist climate. During 11.16―8.60 Ma prevailed forests of cypress and a still warmer, moister climate; steppe vegetation and dry climate began probably at about 8.6 Ma. Although aridification had been relaxed time and again during 8.40―6.93 Ma (forest-steppe, warm-semi-moist), 6.64―5.67 Ma (open-forest and steppe, warmer-semi-moist) and 5.42―4.96 Ma (steppe, semi-arid), the climate in the region became drier and drier in response to the fre- quent occurrence of aridity during 6.93―6.64 Ma (steppe, semi-arid), 5.67―5.42 Ma (de- sert-steppe, arid), 3.66―3.30 Ma (desert-steppe, arid) and 2.56―2.21 Ma (desert, arid). Perhaps the important findings of our study are the notable expansion of drought-enduring plants during 3.66―3.30 Ma and about 2.56 Ma and the replacement of vegetation by vast arid desert. | MA Yuzhen 1 , FANG Xiaomin 1,2 , LI Jijun 1 , WU Fuli 1 & ZHANG Jun 1 1.

| 12 | On the Application of PCA Technique to Fault Diagnosis显示文摘In this paper, we briefly address the application of the standard principal component analysis (PCA) technique to fault detection and identification. Based on an analysis of the existing test statistic, we propose a new test statistic, which is similar to the Hawkin’s TH 2 statistic but without the numerical drawback. In comparison with the SPE index, the threshold setting associated with the new statistic is computationally simpler. Our further study is dedicated to the analysis of fault sensitivity. We consider the off-set and scaling faults, and evaluate the test statistic by viewing its sensitivity to the faults. Our final study focuses on identifying off-set and scaling faults. To this end, two algorithms are proposed. This paper also includes some critical remarks on the application of the PCA technique to fault diagnosis. | DING S ZHANG P DING E YIN S Naik A DENG P GUI W | 2010 | Tsinghua Science and Technology2010,15,2: | 31 |
| 13 | Draining Tangjiashan Barrier Lake after Wenchuan Earthquake and the flood propagation after the dam break显示文摘Tangjiashan Barrier Lake is one of the largest barrier lakes caused by the Wenchuan Earthquake. Its risk analysis, emergency plan and effect of the emergency plan are introduced in this paper. The dam height of Tangjiashan Barrier Dam is about 105 m, and the reservoir storage capacity is 3.2×108 m3. When the dam broke the flood peak were estimated to be larger than 48000 m3/s, which might cause a enormous disaster to the downstream cities and residents. A discharge channel with 13 m deep and 8 m wide was drug, so that the water may flow out of the lake before the dam breaks. As a result, the drainage and risk mitigation project are successful. During the drainage process, the flood peak was about 6500 m3/s, and about 1.6×108 m3 of water was drained off and the residual reservoir capacity was only 8.97×107 m3. A new channel with average width 100 m was formed, which can bear floods of 200 years frequency. The successful experience and the collected data can be used to deal with the similar natural disasters in future. | LIU Ning1, ZHANG JianXin2, LIN Wei3, CHENG WuYI4 & CHEN ZuYu5 1 Ministry of Water Resources of the People’s Republic of China, Beijing 100053, China 2 Bureau of Hydrology of the Ministry of Water Resources of the People’s Republic of China, Beijing 100053, China 3 Sichuan Hydrographic and Water Resources Survey Bureau Chengdu 610031, China 4 HydroChina Chengdu Engineering Corporation, Chengdu 610072, China 5 China Institute of Water Resources and Hydropower Research, Beijing 100044, China | 2009 | Science China(Technological Sciences)2009,52,4: | 29 |
| 14 | Clinicopathological features of gastric glomus tumor显示文摘AIM:To study the clinicopathological features of gastric glomus tumor and review the related Chinese literature published in 1990-2010.METHODS:A case of gastric glomus tumor was re-ported.Clinicopathological findings in 56 cases of gastric glomus tumor were analyzed.RESULTS:Gastric glomus tumor was far more common in women than in men with a female to male ratio of 1.6:1.The median age of the patients was 45 years(range 28-79 years).The patients often complained of epigastric pain and bloody stool.The tumor was located in antrum of the stomach.The greatest diameter of the tumor was 0.8-11cm.Histologically,the tumor was comprised of nests of glomus cells surrounding the capillaries.Glomus cells were small,uniform and round.Vimentin,smooth muscle actin and actin were expressed in the tumor.Other markers,including S-100 protein,CD34,CD117,desmin,CD56,synaptophysin,chromo-granin A,neuron specific enolase and cytokeratin were all negative.CONCLUSION:Gastric glomus tumor is a rare benign mesenchymal neoplasm.Its diagnosis depends on pathologic examination.Differential diagnosis includes gastrointestinal stromal tumor,paraganglioma and carcinoid tumor. | Hui-Qiong Fang,Jing Yang,Fen-Fen Zhang,An-Jia Han,Department of Pathology,First Affiliated Hospital of Sun Yat-Sen University,Guangzhou 510080,Guangdong Province,China Hui-Qiong Fang,Department of Pathology,Foshan Hospital of Traditional Chinese Medicine,Foshan 528000,Guangdong Province,China Jing Yang,Department of Pathology,People’s Hospital of Zhu-hai City,Zhuhai 519000,Guangdong Province,China Yi Cui,Department of Gastroenterology,First Affiliated Hospital of Sun Yat-Sen University,Guangzhou 510080,Guangdong Province,China | 2010 | World Journal of Gastroenterology2010,16,36: | 28 |
| 15 | Geomorphologic evolution and environmental changes in the Shaluli Mountain region during the Quaternary显示文摘Geologic and geomorphologic evidence from the Shaluli Mountain indicates that the planation surface that formed in the Late Tertiary disintegrated during the Late Pliocene-Early Quaternary. At the same time, rift ba- sins appeared on some parts of the planation surface, and began to accumulate fluvial-lacustrine sediment. These are interpreted as being the response of this region to Phase-A of the Qingzang Tectonic Movement. After this, the Shaluli Mountain continued to rise in several pulses. Faulting and incision by some large tributaries of the Jinsha and Yalong Rivers resulted in several rift river valleys and the earliest terraces. Generally, the planation surface in this region had been uplifted to about 3500—3700 m a.s.l. no later than 550—600 ka BP, after the Kunlun-Huanghe Tectonic Move- ment, and coupled with global glacial climate, and resulted in the earliest glaciation recognized so far in the Hengduan Mountains. At the same time, loess was deposited in the Ganzi area of the northern Shaluli Mountain. During the last glacial period, the Shaluli Mountain approached its present altitude and developed several large ice caps, such as the Daocheng Ice Cap and Xinlong Ice Cap, as well as several huge valley glaciers. These paleoglaciers produced some of the most spectacular glacial topography on the Tibetan Pla- teau. | ZHOU Shangzhe1,2, XU Liubing1, CUI Jianxin1, ZHANG Xiaowei1 & ZHAO Jingdong1 1.

| 17 | Interleukin-33 drives hepatic fibrosis through activation of hepatic stellate cells显示文摘Liver fibrosis is a consequence of chronic liver disease,causing morbidity and mortality.Interleukin-33(IL-33)is a critical mediator of inflammation,which may be involved in the development of liver fibrosis.Here,we investigated the role of IL-33 in human patients and experimental bile-duct ligation(BDL)-induced fibrosis in mice.We report increased hepatic IL-33 expression in the murine BDL model of fibrosis and in surgical samples obtained from patients with liver fibrosis.Liver injury,inflammatory cell infiltration and fibrosis were reduced in the absence of the IL-33/ST2 receptor,and the activation of hepatic stellate cells(HSCs)was decreased in ST2-deficient mice.Recombinant IL-33 activated HSCs isolated from C57BL/6 mice,leading to the expression of IL-6,TGF-β,α-SMA and collagen,which was abrogated in the absence of ST2 or by pharmacological inhibition of MAPK signaling.Finally,administration of recombinant IL-33 significantly increased hepatic inflammation in sham-operated BL6 mice but did not enhance BDL-induced hepatic inflammation and fibrosis.In conclusion,BDL-induced liver inflammation and fibrosis are dependent on ST2 signaling in HSCs,and therefore,the IL-33/ST2 pathway may be a potential therapeutic target in human patients with chronic hepatitis and liver fibrosis. | Zhongming Tan Qianghui Liu Runqiu Jiang Long Lv Siamak S Shoto Isabelle Maillet Valerie Quesniaux Junwei Tang Wenjie Zhang Beicheng Sun Bernhard Ryffel | 2018 | Cellular & Molecular Immunology2018,15,4: | 24 |

| 19 | Ten-year survival of hepatocellular carcinoma patients undergoing radiofrequency ablation as a first-line treatment显示文摘AIM: To investigate the long-term survival and prognostic factors in hepatocellular carcinoma(HCC) patients undergoing radiofrequency ablation(RFA) as a first-line treatment.METHODS: From 2000 to 2013, 316 consecutivepatients with 404 HCC(1.0-5.0 cm; mean: 3.2 ± 1.1 cm) underwent ultrasonography-guided percutaneous RFA as a first-line treatment. There were 250 males and 66 females with an average age of 60.1 ± 10.8 years(24-87 years). Patients were followed for 1 year to > 10 years after RFA(234, 181, 136, and 71 for 3, 5, 7, and 10 years, respectively). Overall local response rates and long-term survival rates were assessed. Survival results were generated using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression model. RESULTS: In total, 548 RFA sessions were performed and major complications occurred in 10 sessions(1.8%). Local tumor progression and/or new tumor development were observed in 43.3%(132/305) of the patients during the follow-up period. Overall 5-and 10-year survival rates were 49.7% and 28.4%, respectively. Based on multivariate analysis, three factors were identified as independent prognostic factors for overall survival: Child-Pugh classification(HR = 4.054, P < 0.001), portal vein hypertension(HR = 2.743, P = 0.002), and tumor number(HR = 2.693, P = 0.003). The local progression-free 5- and 10-year survival rates were 42.7% and 19.5%. In addition to the Child-Pugh classification and the number of tumors, the number of RFA sessions(HR = 1.550, P = 0.002) was associated with local progression-free survival.CONCLUSION: RFA can achieve acceptable outcomes for HCC patients as a first-line treatment, especially for patients with Child-Pugh class A, patients with a single tumor and patients without portal vein hypertension. | Wei Yang Kun Yan S Nahum Goldberg Muneeb Ahmed Jung-Chieh Lee Wei Wu Zhong-Yi Zhang Song Wang Min-Hua Chen | 2016 | World Journal of Gastroenterology2016,22,10: | 20 |
| 20 | Effect of N-desulfated heparin on hepatic/renal ischemia reperfusion injury in rats显示文摘AIM: To investigate the effect of N-desulfated heparin onhepatic/renal ischemia and reperfusion injury in rats.METHODS: Using rat models of 60 minutes hepatic or renalischemia followed by 1 h,3 h,6 h and 24 h reperfusion,animalswere randomly divided into following groups,the shamoperated controls,ischemic group receiving only normalsaline,and treated group receiving N-desulfated heparin ata dose of 12 mg/kg at 5 minutes before reperfusion. P-selectin expression was detected in bepatic/renal tissueswith immunohistochemistry methodRESULTS: P-selectin expression, serum ALT, AST, BUN andCr levels were significantly increased during 60 minuteischemia and 1 h, 3 h, 6 h and 24 h reperfusion,while theincrement was significantly inhibited,and hepatic/renalpathology observed by light microscopy was remarkablyimproved by treatment with the N-desulfated heparin.Furthermore,the heparin was found no effects on PT and KPTT.CONCLUSION: P-selectin might mediate neutrophilinfiltration and contribute to hepatic/renal ischemia andreperfusion. The N-desulfated heparin might preventhepatic/renal damage induced by ischemia and reperfusioninjury without significant anticoagulant activity. | Tong Zhou Wei Song Feng Wang Department of Nephrology,Ruijin Hospital,Shanghai Second Medical University,Shanghai 200025,China Jin-Lian Chen Department of Gastroenterology,Shanghai Sixth People’s Hospital,Shanghai 200233,China Ming-Jun Zhang Animal Laboratory,Ruijin Hospital,Shanghai Second Medical University,Shanghai 200025,China Pei-Hua Ni,Department of Biochemistry,Shanghai Second Medical University,Shanghai 200025 Jian-Guo Geng Institute of Biochemistry and Cell Biology,Shanghai 200030,China | 2002 | World Journal of Gastroenterology2002,8,5: | 20 |
