1.Some epidemiological characteristics of poliomyelitis in North Vietnam in the years 1992-1999
Journal of Practical Medicine 2002;435(11):41-42
Data were collected from the Enlarged Immunization Program and the Poliomyelitis Eradication Program (1992-1999), also including inquiry forms and guidelines for detecting, investigating, and processing by Epi-Info. Results shown the epidemic was spread in prevailing of rural population (79.3%), under 5 years old children accounted for 87.9% of cases of poliomyelitis. The outbreaks occurred all around the year with the peak on March, April, May and September, October. Wild virus of the type 1 plays the main role in 97.8% of cases

Background: Acute Respiratory Infection (ARI) is a common disease in developing countries. Morbidity and mortality of ARI are high, especially among children under 15 years old. Objectives: To describe socio-graphic factors, seasonal patterns, risky areas and determine the morbidity and mortality rates of acute respiratory infections in Thai Binh province. Subjects and method: This retrospective study reviewed the medical records of 4,585 hospital admitted patients who were diagnosed with ARI including upper and lower respiratory infections such as sore throat, pharyngitis, bronchitis, pneumonia and bronchitis-pneumonia at 8 district hospitals and 1 provincial hospital in Thai Binh province during 2002-2005. The selected medical records were based on the available check list and two standard screening tests. Results:Morbidity and mortality of ARI in Thai Binh province were 61.6 and 0.52, respectively. ARI mainly occurred among children under 5 years old, of which the highest mortality was among those under 12 months of age. Male children were at higher risk of acquiring ARI, but less prone to death than female. Occupation did not significantly associate with the risk of ARI. The morbidity increased sharply during inter-season, e.g. March and October. Thai Binh city, Kien Xuong and Tien Hai district were reported with the highest morbidity in accompany of the high mortality as consequences. Conclusion: The prevention and control methods were recommended to annually focus on the male children aged less than 5 years old during March and October in Thai Binh city, Kien Xuong and Tien Hai district.

Background: With the help of Japan, the Center for Research and Production of vaccines and biologicals, Hanoi has received a WHO standard measles vaccine production technology, including techniques in the examination of vaccine quality. Therefore, it is needed to be initiative on production of measles antibody. Objective: Study on production of measles antibody in rabbits and selecting the appropriate antibody for production of high titre antibody, which meets the standard of vaccine quality control in Vietnam. Subject and methods: Using the measles antigen from Edmonston and AIK-C strains, which were provided by the Kitasato Institute, to produce measles antibody. Making immunoreaction in rabbits and determination of neutralization antibody titre. Results and Conclusion: Measles antigen of Edmonston Vero 7/P2 strain used in the production of measles antibody in rabbit created the highest antibody titre in comparison with AIK-C strain from vero cell and FL cell supplied by the Kitasato Institute of Japan. Antibody titre of Edmonston Vero 7/P2 strain reached up to 1/8192 and met the sera standard required for measles vaccine quality control, it is similar to the measles sera to be produced from the Kitasato Institute.

Anthocyanins are naturally occuring phytochemicals and the main components of the coloring of plants, flowers and fruits. They are known to elicit antioxidative, anti-inflammatory and cancer preventive activity. In this study, we investigated anthocyanins in black / yellow soybean seedcoats using different methods of detection - thin layer chromatography (TLC), capillary zone electrophoresis (CZE) and HPLC analysis. The anthocyanins in soybean seedcoats were extracted by five independent methods of extraction and the aglycons (anthocyanidins) of the corresponding anthocyanins were prepared by acid mediated hydrolysis. The anthocyanin / anthocyanidin in black soybean seedcoat showed characteristic TLC mobility, CZE electrophoretic retention and HPLC migration time while little of anthocyanins were detected from yellow soybean seedcoat. The extracted anthocyanins showed pH dependent retention time in CZE and spectral change in UV-Vis spectrum. HPLC analysis of the hydrolyzed extract of black soybean seedcoat identified the presence of four anthocyanidins. The major anthocyanin in black soybean seedcoat was cyanin (cyanidin-3-O-glucoside), with the relative order of anthocyanidin in cyanidin > delphinidin > petunidin > pelargonidin.

Although the introduction of stem cell transplantation and novel agents has improved survival, multiple myeloma (MM) is still difficult to cure. Alternative approaches are clearly needed to prolong the survival of patients with MM. Dendritic cell (DC) therapy is a very promising tool immunologically in MM. We developed a method to generate potent DCs with increased Th1 polarization and migration ability for inducing strong myeloma-specific cytotoxic T lymphocytes. In this review, we discuss how the efficacy of cancer immunotherapy using DCs can be improved in MM.

OBJECTIVETo investigate the inhibited effect of epigallocatechin-3-gallate (EGCG) on the expression of NPM1 in IMS-M2 cells harboring the NPM1 mutations.
METHODSCell proliferation assay was performed to test the effects of EGCG on cell growth of IMS-M2 cells harboring the NPM1 mutations. Western blot analysis were performed to test the protein expression of NPM1, AKT, those associated with apoptosis.
RESULTSEGCG can down-regulate the expression of NPM1 in IMS-M2 cells harboring the NPM1 mutations. Moreover, EGCG also suppressed the cell proliferation and induced apoptosis in IMS-M2 cells.
CONCLUSIONSThe results suggested that EGCG could be considered as a reagent for treatment of AML patients with NPM1 mutations.
