7Geochemistry and regional distribution of ophiolites and associated volcanics in Mianlüe suture, Qinling-Dabie Mountains显示文摘Systematic studies of the ophiolites and associated volcanics stretching more than 1500 km from the Derni-Nanping-Pipasi-Kangxian area in the west to the Qingshuihe area of the south Dabie Mountains in the east indicate the existence of a suture zone (the Mianl黣 suture) and a vanished paleo-ocean basin (the Mianl黣 paleo-ocean basin) in the region. From west to east, ophiolitic mlange associations distribute discontinuously along the suture. Rock assem-blages include ophiolite, island arc and oceanic island rock series. The Mianl黣 paleo-ocean basin experienced its major formation and expending episode during the Carboniferous-Permian period. The finding of the suture zone and the paleo-ocean basin is tectonically significant in timing the collision between the North China-Qinling and Yangtze blocks and determining the formation and evolution of the Qinling orogenic belt.LAI Shaocong, ZHANG Guowei, DONG Yunpeng, PEI Xianzhi & CHEN Liang Key Laboratory of Continental Dynamics, Ministry of Education and Department of Geology, Northwest University, Xian 710069, China 2004Science China Earth Sciences2004,47,4:25
8Antidepressant-like effect of essential oil of Perilla frutescens in a chronic, unpredictable, mild stress-induced depression model mice显示文摘Perilla frutescens(Perilla leaf), a garnishing vegetable in East Asian countries, as well as a plant-based medicine, has been used for centuries to treat various conditions, including depression. Several studies have demonstrated that the essential oil of P. frutescens(EOPF) attenuated the depressive-like behavior in mice. The present study was designed to test the anti-depressant effects of EOPF and the possible mechanisms in an chronic, unpredictable, mild stress(CUMS)-induced mouse model. With the exposure to stressor once daily for five consecutive weeks, EOPF(3, 6, and 9 mg·kg-1) and a positive control drug fluoxetine(20 mg·kg-1) were administered through gastric intubation to mice once daily for three consecutive weeks from the 3rd week. Open-field test, sucrose consumption test, tail suspension test(TST), and forced swimming test(FST) were used to evaluate the behavioral activity. The contents of 5-hydroxytryptamine(5-HT) and its metabolite, 5-hydroxyindoleacetic acid(5-HIAA), in mouse hippocampus were determined by HPLC–ECD. Serum interleukin(IL)-1, IL-6, and tumor necrosis factor(TNF)-α levels were evaluated by enzyme-linked immunosorbent assay(ELISA). The results showed that CUMS significantly decreased the levels of 5-HT and 5-HIAA in the hippocampus, with an increase in plasma IL-6, IL-1β, and TNF-α levels. CUMS also reduced open-field activity, sucrose consumption, as well as increased immobility duration in FST and TST. EOPF administration could effectively reverse the alterations in the concentrations of 5-HT and 5-HIAA; reduce the IL-6, IL-1β, and TNF-α levels. Moreover, EOPF could effectively reverse alterations in immobility duration, sucrose consumption, and open-field activity. However, the effect was not dose-dependent. In conclusion, EOPF administration exhibited significant antidepressant-like effects in mice with CUMS-induced depression. The antidepressant activity of EOPF might be related to the relation between alteration of serotonergic responses and anti-inflammatory effects.JI Wei-Wei LI Rui-Peng LI Meng WANG Shu-Yuan ZHANG Xian NIU Xing-Xing LI Wei YAN Lu WANG Yang FU Qiang MA Shi-Ping 2014Chinese Journal of Natural Medicines2014,12,10:26

12Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng 2012Biomedical and Environmental Sciences2012,25,2:23

14Multiple imaging techniques in the diagnosis of ampullary carcinoma显示文摘BACKGROUND:Ampullary carcinoma is a neoplasia with a good prognosis compared to pancreatic cancer. But it is difficult to early diagnose because it lacks clear clinical symptoms.This study aimed to evaluate the efficacy of abdominal ultrasonography(US),enhanced computed tomography(CT),magnetic resonance cholangiopancreatography(MRCP)and endoscopic retrograde cholangiopancreatography(ERCP)in detecting ampullary carcinoma. METHODS:Forty-one patients with ampullary carcinoma who had been confirmed pathologically among the inpatients at the First Affiliated Hospital of Zhejiang University School of Medicine from February 2003 to March 2007 were analyzed retrospectively.The accuracy of US,CT,MRCP and ERCP were compared in the diagnosis of ampullary carcinoma. RESULTS:The accurate rate for detection of ampullary carcinoma with US was 26.83%.The accuracy of CT and ERCP in detection of ampullary tumors was 84.62%and 100%,respectively,which were significantly higher than that of US(P<0.05).The accuracy of MRCP in detection of ampullary tumors was similar to that of US in spite of visualization of obstruction and dilatation of the pancreaticobiliary duct with MRCP. CONCLUSIONS:Because of the obscure and late onset of symptoms,ampullary carcinoma is difficult to diagnose early.Multiple imaging techniques should be carried out appropriately in order to early diagnose the disease and improve the prognosis.Chen, Wei-Xing Xie, Qi-Gui Zhang, Wei-Fang Zhang, Xian Hu, Tian-Tian Xu, Ping Gu, Zhu-Ying 2008Hepatobiliary & Pancreatic Diseases International2008,7,6:20

18Potentially predictive microRNAs of gastric cancer with metastasis to lymph node显示文摘AIM:To detect the expression of 60 microRNAs(miRNAs)in gastric cancer tissues and find new predictive biomarkers of gastric cancer with metastasis.METHODS:The expressions of 60 candidate miRNAs in 30 gastric cancer tissues and paired normal tissues were detected by stem-loop real-time reverse transcription-polymerase chain reaction.After primary screening of miRNAs expression,5 selected miRNAs were further testified in another 22 paired gastric tissues.Based on the expression level of miRNAs and the status of metastasis to lymph node(LN),receiver-operating-characteristic(ROC)curve were used to evaluate their ability in predicting the status of metastasis to LN.RESULTS:Thirty-eight miRNAs expressions in gastric cancer tissues were significantly different from those in paired normal tissues(P<0.01).Among them,31miRNAs were found to be up-expressed in cancer tissues and 1 miRNAs were down-expressed≥1.5 fold vs paired normal gastric tissue.Five microRNAs(miR-125a-3p,miR-133b,miR-143,miR-195 and miR-212)were differently expressed between different metastatic groups in 30 gastric cancer biopsies(P<0.05).Partial correlation analysis showed that hsa-mir-212 and hsa-mir-195 were correlated with the status of metastasis to LN in spite of age,gender,tumor location,tumor size,depth of invasion and cell differentiation.ROC analysis indicated that miR-212 and miR-195 have better sensi-tivities(84.6%and 69.2%,respectively)and specifici-ties(both 100%)in distinguishing biopsies with metastasis to LN from biopsies without metastasis to LN.CONCLUSION:miR-212 and miR-195 could be independent biomarkers in predicting the gastric cancer with metastasis to LN.Wen-Yi Wu Xiang-Yang Xue Zhe-Jing Chen Shao-Liang Han Ying-Peng Huang Li-Fang Zhang Guan-Bao Zhu Xian Shen 2011World Journal of Gastroenterology2011,17,31:15
19Bone morphogenetic protein-7 represses hepatic stellate cell activation and liver fibrosis via regulation of TGF-β/Smad signaling pathway显示文摘BACKGROUND Liver fibrosis is a refractory disease whose persistence can eventually induce cirrhosis or even liver cancer.Early liver fibrosis is reversible by intervention.As a member of the transforming growth factor-beta(TGF-β)superfamily,bone morphogenetic protein 7(BMP7)has anti-liver fibrosis functions.However,little is known about BMP7 expression changes and its potential regulatory mechanism as well as the relationship between BMP7 and TGF-βduring liver fibrosis.In addition,the mechanism underlying the anti-liver fibrosis function of BMP7 needs to be further explored.AIM To investigate changes in the dynamic expression of BMP7 during liver fibrosis,interactions between BMP7 and TGF-β1,and possible mechanisms underlying the anti-liver fibrosis function of BMP7.METHODS Changes in BMP7 expression during liver fibrosis and the interaction between BMP7 and TGF-β1 in mice were observed.Exogenous BMP7 was used to treat mouse primary hepatic stellate cells(HSCs)to observe its effect on activation,migration,and proliferation of HSCs and explore the possible mechanism underlying the anti-liver fibrosis function of BMP7.Mice with liver fibrosis received exogenous BMP7 intervention to observe improvement of liver fibrosis by using Masson’s trichrome staining and detecting the expression of the HSC activation indicator alpha-smooth muscle actin(α-SMA)and the collagen formation associated protein type I collagen(Col I).Changes in the dynamic expression of BMP7 during liver fibrosis in the human body were further observed.RESULTS In the process of liver fibrosis induced by carbon tetrachloride(CCl4)in mice,BMP7 protein expression first increased,followed by a decrease;there was a similar trend in the human body.This process was accompanied by a sustained increase in TGF-β1 protein expression.In vitro experiment results showed that TGF-β1 inhibited BMP7 expression in a time-and dose-dependent manner.In contrast,high doses of exogenous BMP7 inhibited TGF-β1-induced activation,migration,and proliferation of HSCs;this inhibitory effect was associated with upregulation of pSmad1/5/8 and downregulation of phosphorylation of Smad3 and p38 by BMP7.In vivo experiment results showed that exogenous BMP7 improved liver fibrosis in mice.CONCLUSION During liver fibrosis,BMP7 protein expression first increases and then decreases.This changing trend is associated with inhibition of BMP7 expression by sustained upregulation of TGF-β1 in a time-and dose-dependent manner.Exogenous BMP7 could selectively regulate TGF-β/Smad pathway-associated factors to inhibit activation,migration,and proliferation of HSCs and exert antiliver fibrosis functions.Exogenous BMP7 has the potential to be used as an antiliver fibrosis drug.Gao-Liang Zou Shi Zuo Shuang Lu Rui-Han Hu Yin-Ying Lu Jing Yang Kai-Sheng Deng Ye-Ting Wu Mao Mu Juan-Juan Zhu Jing-Zhang Zeng Bao-Fang Zhang Xian Wu Xue-Ke Zhao Hai-Yang Li 2019World Journal of Gastroenterology2019,25,30:15
