2Reduction of the incidence and mortality of rectal cancer bypolypectomy:a prospective cohort study in Haining County显示文摘AIM: To reduce the incidence and morlality of rectal cancerand address the hypothesis that colorectal cancer often arisefrom precursor lesion (s), either adenomas or non-alenomatous polyps, by conducting a population-basedmass screening for colorectal cancer in Haining County,Zhejiang, PRCMETHODS: From 1977 to 1980, physicians screened thepopulation of Haining County using 15 cm rigid endoscopy.Of over 240 000 participants, 4076 of them were diagnoselwith Precursor Iesions, eitler alenomas or non-adenomatous polyps, which were then removedl surgically.All individuals with precursor lesionswere followed up andreexamined by endoscopy every two to five years upto 1998.RESULTS: After the initial screening, 953 metactronousadenomas and 417 non-adenomatous polyps ware detected andremoved from the members of this cohort. Further, 27 cases ofcolorectal cancer were detected and treated. Log-rank tuestsshowed that the survival time among those cancer patients whounderwent mass screening increased significantly comparedtothat of other colorectal cancer patients (P < 0.0001). Accordingto the population-based cancer registry in Haining County,age-adjusted incidence and mortality of rectal cancer decreasedby 41% and 29 % from 1977-1981 to 1992-1996, respectively.Observed cumulative 20-year rectal cancer incidence was 31%lower than the expected in the screened group; the mortalitydue to rectal cancer was 18 % lower thah the expected in thescreened group.CONCLUSION: Mass screening for rectal cancer andprecursor lesions with protocoscopy in the generalpopulation and periodical following-up with routineendoscopy for high-risk patients may decrease both theincidence and mortality of rectal cancer.Shu Zheng Xi-Yong Liu Qi Dong,Cancer Institute,Zhejiang University,88 Jiefang Road,HangZhou 310009,Zhejiang Province,China Ke-feng Ding Lin-Bo Wang Pei-Lin Qiu Su-Zhan Zhang,The 2~(nd)affiliated Hospital,Medical School of Zhejiang University,88 Jiefang Road,HangZhou 310009,Zhejiang Province,China Xin-Feng Ding Yong-Zhou Shen Gao-Fei Shen Oi-Rong Sun Wei-Dong Li,Haining Cancer Institute,Haining 314400,Zhejiang Province,China 2002World Journal of Gastroenterology2002,8,3:37
3Evaluation of liver functional reserve by combining D-sorbitol clearance rate and CT measured liver volume显示文摘AIM: Our research attempted to evaluate the overall functional reserve of cirrhotic liver by combination of hepatic functional blood flow, liver volume, and ChildPugh′s classification, and to discuss its value of clinical application.METHODS: Ninety two patients with portal hypertension due to hepatic cirrhosis were investigated. All had a historyof haematemesis and hematochezia, esophageal and gastric fundus varices, splenomegaly and hypersplenia.A 2-year follow-up was routinely performed and no one was lost. Twenty two healthy volunteers were used as control group. Blood and urine samples were collected 4times before and after intravenous D-sorbitol infusion.The hepatic clearance (CLH) of D-sorbitol was then calculated according to enzymatic spectrophotometric method while the total blood flow (QToTAL) and intrahepatic shunt (RINs) were detected by multicolor Doppler ultrasound, and the liver volume was measured by spiral CT. Data were estimated by t-test, variance calculation and chi-squared test. The relationships between all these parameters and different groups were investigated according to Child-Pugh classification and postoperative complications respectively.RESULTS: Steady blood concentration was achieved 120 mins after D-sorbitol intravenous infusion, which was (0.358±0.064) mmoⅠ@L-1 in cirrhotic group and (0.189±0.05)mmol@L-1 in control group (P<0.01). CLH=(812.7±112.4) ml@min-1,QTOTAL=(1280.6±131.4) ml@min-1, and RINS=(36.54±10.65)%in cirrhotic group and CLH=(1248.3±210.5) ml.min-1, QTOTAL=(1362.4-±126.9) ml@min-1, and RINS=(8.37±3.32) % in control group (P<0.01). The liver volume of cirrhotic group was 1057±249 cm3, 851±148 cm3 and 663±77 cm3 in Child A, B and C group respectively with significant difference (P<0.001).The average volume of cirrhotic liver in Child B, C group was significantly reduced in comparison with that in control group (P<0.001). The patient, whose liver volume decreased by 40 % with the CLH below 600 ml@min-1, would have a higher incidence of postoperative complications. There was no strict correspondent relationship between CLH, liver volume and Child-Pugh′s classification.CONCLUSION: The hepatic clearance of D-sorbitol, CT measured liver volume can be reliably used for the evaluation of hepatic functional blood flow and liver metabolic volume. Combined with the Child-Pugh′s classification, it could be very useful for further understanding the liver functional reserve, therefore help determine reasonable therapeutic plan, choose surgical procedures and operating time.Yi-Ming Li Fan Lv Xin Xu Hong Ji Wen-Tao Gao Tuan-Jie Lei Gui-Bing Ren Zhi-Lan Bai Qiang Li General Surgery Department,the 2~(nd)Affiliated Hospital of Xi’an Jiaotong University,Xi’an 710004,ShaanXi Province,China 2003World Journal of Gastroenterology2003,9,9:16
4Rainfall interception by sand-stabilizing shrubs related to crown structure显示文摘On the edge of the Tengger Desert in northern China,revegetation has changed the landscape from moving dunes to stabilized dunes covered by shrubs,which further modifies the pattern of rainfall redistribution.To study rainfall interception loss by shrubs and its relationship to rainfall properties and crown structure,throughfalls passing through crowns of Artemisia ordosica Krash.and Caragana korshinskii Kom.were measured using nine PVC cups under the canopy of each of the two shrubs during 73 rain events over a three-year period,with total rainfall of 260.9 mm.Interception losses of gross rainfall by A.ordosica and C.korshinskii account for 15% and 27% of the total on a crown area basis,and 6% and 11% on a ground area basis,respectively.Individual throughfall(T) and interception(I) were significantly related to rainfall amount(Pg),duration(D),and intensity(R).Ratios of throughfall to rainfall(T/Pg) and interception to rainfall(I/Pg) were not only significantly related to Pg,D,and R,but also to shrub species,and interactions of species with crown volume(CV) and leaf area index(LAI).Under most rain events,interceptions by C.korshinskii with greater CV and LAI were significantly higher than those by A.ordosica,and more rainfall interception occurred at locations closer to the stems of the two shrubs.For C.korshinskii,I/Pg had a significant positive linear relation with CV and LAI,while T/Pg had a significant negative linear relation with them.CV has a greater influence on T/Pg and I/Pg than does LAI.Using a regression method,canopy water storage capacities are estimated to be 0.52 and 0.68 mm,and free throughfall coefficient to be 0.62 and 0.47 for A.ordosica and C.korshinskii,respectively.ZhiShan Zhang 1*,XinRong Li 1,XueJun Dong 2,XiaoHong Jia 1,MingZhu He 1,HuiJuan Tan 1 1.Shapotou Desert Research and Experiment Station,Cold and Arid Regions Environmental and Engineering Research Institute,Chinese Academy of Sciences,Lanzhou,Gansu 730000,China.2.Central Grasslands Research Extension Center,North Dakota State University,Streeter,ND 58483,USA. 2009Research in Cold and Arid Regions2009,1,2:9

8Impact of proteolytic enzymes in colorectal cancer development and progression显示文摘Tumor invasion and metastasis is a highly complicated, multi-step phenomenon. In the complex event of tumor progression, tumor cells interact with basement membrane and extracellular matrix components. Proteolytic enzymes(proteinases) are involved in the degradation of extracellular matrix, but also in cancer invasion and metastasis. The four categories of proteinases(cysteine-, serine-, aspartic-, and metalloproteinases) are named and classified according to the essential catalytic component in their active site. We and others have shown that proteolytic enzymes play a major role not only in colorectal cancer(CRC) invasion and metastasis, but also in malignant transformation of precancerous lesions into cancer. Tissue and serumplasma antigen concentrations of proteinases might be of great value in identifying patients with poor prognosis in CRC. Our results, in concordance with othersindicate the potential tumor marker impact of proteinases for the early diagnosis of CRC. In addition, proteinases may also serve as potential target molecules for therapeutic agents.László Herszényi Loránd Barabás István Hritz Gábor István Zsolt Tulassay 2014World Journal of Gastroenterology2014,20,37:3

11Lactic acid bacteria as pro-technological,bioprotective and health-promoting cultures in the dairy food industry显示文摘Lactic acid bacteria (LAB) constitute pivotal microorganisms for the food industry due to their considerable technological and functional potential.Fermented dairy products,that is ancient traditions worldwide,still have been accepted and consumed today for their nutritional and organoleptic attributes.In accordance with the current trends in the market and greater awareness of consumer well-being,a detailed assessment of the health effects of dairy product consumption has been undertaken with particular reference to the production of bioactive metabolites including i.e.,γ-aminobutyric acid,conjugated linoleic acid,bioactive peptides,exopolysaccharides as well as vitamins during LAB fermentation.The long histories of yogurt,kefir,and traditional fermented milk drink as sources of some certain probiotic bacteria as well as the opportunity to bio-fortify the matrix with bioactive microbial compounds in situ make fermented dairy products an attractive model in the efforts to develop sustainable functional food systems.Therefore,this review provides the main biochemical characteristics and biotechnological application of LAB as pro-technological,bioprotective,and health-promoting in the food chain.Duygu Ağagündüz Teslime Özge Şahin Şerife Ayten Birsen Yılmaz Bartu Eren Güneşliol Pasquale Russo Giuseppe Spano Fatih Özogul 2022Food Bioscience2022,47,3:2
12Relationship between metabolic syndrome and erectile dysfunction显示文摘Aim: To determine the relationship between metabolic syndrome (MS) and erectile dysfunction (ED) and to see which risk factors correlated the best with ED. Methods: Seventy-nine cardiology clinic outpatients with coronary artery disease (CAD) and lipid metabolism disorder were recruited. They were categorized as having MS,hypertension (blood pressure greater than 130/85 mmHg) and dyslipidemia. ED was classified based on International Index of Erectile Function scores. Patients were grouped into quartiles based on body mass index (BMI). Chi-square,Pearson's correlation and regression tests were used for statistical analysis. Results: The mean age of the patients was 56.6 years. ED was diagnosed in 59 (74.7 %) of the 79 patients. In the 38 patients with MS, all had ED. ED was not significantly correlated with cholesterol levels (P>0.05), but was found often in patients who had both hypercholesterolemia and HT (P<0.01). Nineteen(76 %) of the 25 patients who had dyslipidemia had ED. However, ED wasnot significantly correlated with dyslipidemia (P>0.05). Tweenty-two of the 23 patients who had BMI greater than30 had ED, which was significantly more prevalent than that in those who had normal BMI (P<0.01). ED was seen in 38 of 53 smoker patients. Although ED was more prevalent in cigarette smokers, it was not significantly different from non-smokers (P>0.5). Conclusion: ED is present in a high percentage of patients with MS. Among multiple risk factors for ED, MS correlates the most highly. The next most important risk group is the patients with hypertension +hypercholestrolemia and obesity (BMI>30).
