Abstract: The two nitrogen atoms in the structure of dimethylaminopyridine (DMAP) may be able to combine with hydrogen ion and form the corresponding conjugated acid, which may enable DMAP to exhibit the characteristics of second order ionization. In view of this, the ionization characteristic of DMAP is determined by neutralizing titration. The experiment result shows that only the nitrogen atom on pyri-dine ring has the ability to form the conjugated acid and the according pKa is 9.6 at 25C. In order to remove DMAP catalyst in the acylation system of oligosaccharide which has the same good solvency as DMAP in water, the dynamic absorption characteristics of DMAP adsorbed by 732 cation exchanger were studied and the appropriate operation conditions were obtained as follows: the concentration of DMAP solution was about 10 g L-1, pH was kept at 9, and the flowrate was 1.3 mL-min-1.

Abstract: As opportunities to gamble have increased during the 20th century, so has gambling research. This study used new strategies, methods, and technology to examine citation trends and the growth of knowledge in the field of gambling studies. The sample included 2,246 citations that were published between 1903 and 2003. By using multiple keywords to classify each citation into distinct topic areas, this study yielded a more comprehensive analysis than was previously available. The results reveal that gambling-related research has grown at an exponential rate. The most prevalent topics explored within gambling studies citations have been pathology, risk-taking, decision-making and addiction. Between 1999 and 2003, studies addressing epidemiology, drug abuse, comorbidity and neuroscience have become increasingly prevalent. Based on these trends and their implications, this paper provides several recommendations for both future areas of inquiry within the field of gambling studies and better classification techniques for citations within all fields of psychology.

Abstract: Background. Although Japan’s contributions to several biomedical fields have already been reported, little is known about Japan’s contribution to gastroenterology and hepatology. Methods. Original articles published in 1991 through 2000 in highly reputed journals in the field of gastroenterology and hepatology were retrieved from the MEDLINE database. The number of articles having an affiliation with a Japanese institution was counted in total, and the number for each journal was also counted. Japan’s share of articles regarding clinical trials and randomized controlled trials (RCTs) in this field was also determined, along with the trend over the past decade. Results. Japan’s share of articles in this field was 10.6%, ranking third in the world, following the United States (35.1%) and the United Kingdom (11.5%). Japan’s share of articles went up significantly as a whole (P = 0.01), while the share for RCTs showed no significant change (P = 0.57) during this period of time. Conclusions. Japan’s contribution to the field of gastroenterology and hepatology is, in general, acceptable compared with that of other counties, but the contribution for RCTs not satisfactory.

Abstract: Hepatocellular carcinoma (HCC) is one of the major cancers in China. Accordingly, the mortality rates in 1990 (per 100,000) were 20.10 in certain cities and 24.32 in certain counties. More than 90% of HCC cases and 70% of controls were infected with the hepatitis B virus (HBV) (Odds Ratio (OR) = 10-50). In the same group of patients, 8-27% of those with HCC and 0-11% of the healthy controls were also infected with hepatitis C (HCV) (OR = 2.11-17.29). There appears to be some correlation between HBV markers and the OR. The government requires that 85% of infants be immunized with HBV vaccine. In, (1992), there were 3 million infants inoculated with HB vaccines. Aflatoxins have been found as contaminants in food, particularly in corn, peanut oil, soya sauce and fermented soya beans. The intake of aflatoxin B1 (AFB1) by people of ten different villages correlated with HCC mortality rates (r = 0.55; P < 0.05). The concentration of AFB1-albumin adducts is an indicator of individual exposure to aflatoxins. These adducts are higher in hyperendemic HCC areas and cases. Most people have now changed their staple food and eat rice instead of corn. Six large epidemiological studies have confirmed that people who drink pond-ditch water experience higher HCC mortality rates than people who drink deep-well water. Recent research has found that the blue-green algal toxin microcystin (MCYST) was a contaminant of pond-ditch water. MCYST is a strong promoter of HCC and will induce severe intrahepatic haemorrhages and liver necrosis. More than 80% of people in Qidong County have already changed their sources of water from pond-ditches to deep wells. Therefore, a combined strategy of the prevention of hepatitis, control of crops and control of drinking water is advocated for the primary prevention of HCC in China.

Full Text: 2009\J Gas Hep24, 1710.pdf

Abstract: Background and Aim: The use of wire-guided cannulation (WGC) for prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is controversial. The aim of the present study was to assess the overall effect of WGC for PEP compared with conventional contrast-assisted cannulation by carrying out a meta-analysis of all available randomized controlled trials (RCT). Methods: Electronic databases, including PubMed, EMBASE, the Cochrane library and the Science Citation Index, were searched to retrieve relevant trials. In addition, meeting abstracts and the reference lists of retrieved articles were reviewed for further relevant studies. Outcome measures were the incidence of PEP. Results: Four RCT, enrolling a total of 1413 patients, were included. The meta-analysis failed to indicate a significant association between the use of WGC and the reduction of PEP (RR 0.34; 95% CI: 0.10-1.17; P = 0.09). Subgroup analysis including trials without cross-over design showed a significant benefit with the use of WGC in reducing PEP (RR 0.20; 95% CI: 0.09-0.40; P < 0.00001) and trials without precut used failed to indicate a significant differences between the two group (RR 0.38; 95% CI: 0.01-11.73; P = 0.58). Conclusions: This meta-analysis showed only a non-significant reduction in the rate of PEP with the use of WGC. Further well-designed RCT are required to confirm the effect of WGC, especially in patients who were easier to cannulate.
