40 patients with gastroduodenal ulceration and positive H.pylori treated by pansiron, amoxycilline and metronidazole within 10 days. The results have shown that pansiron G was a drug that cover the gastric mucosa well and heal 70% of ulceration focuses. The H.pylori killing rate by the above outline was 65,7%.

Studying on 35 patients were preoperative diagnosed as pancreatic adenocarcinoma received operations in ViÖt §øc hospital during 2000-2001 showed that: 29 patients with pancreatic adenocarcinoma and 6 patients without the disease. The two dimensional ultrasound found 18 cases (62%) with specificity (50%) and correct (60%), value of positive predict (85.7%). The rate of precise diagnosis of two dimensional ultrasound, CT scanner, and endoscopic ultrasound were 60%, 72.7%, and 83.3%, respectively.

Background: Che day is a commonly used traditional medicine among the mountainous ethnic people to treat gastro-duodenal ulcer. Its scientific name is Ampelopsis Cantoniensis Planch (Vitaceae). It is known that chemical components of che day includes flavonoid, tanin and uronic compound, which is able to relieve pain completely. Objectives: Evaluation of analgesic, cicatrisation, anti-inflammation and Helicobacter Pylori (HP) eradicating effects of che day in the treatment of gastro-duodenal ulcer and also investigate the side effects of che day. Subject and methods: 80 patients with gastro-duodenal ulcers were seen with endoscopy, suffering from epigastric pain. The study was carried out in the way of a double - blind method, comparing the results between the group che day and the Alusi cotrolled group. Results: On average, the time when the pain receded is 8.9 days in the che day group, faster than the Alusi controlled group (17.35 days, p < 0.01). The rate of the cicatrisation by che day is 79.55%, higher than the Alusi (47.22%; p < 0.001). In pathological anatomy, the rate of HP eradicating of che day is 42.5%, higher than the Alusi (19.35%, p < 0.01); the rate of recovery from gastritis of che day is 23.25%, higher than the Alusi (9.09%, p < 0.01) and the rate of total recovery of che day is 44.19%, higher than the Alusi; (27.27%, p < 0.01), Conclusions: The che day is effective in relieving gastro-duodenal ulcer \u2013 induced pain for the average of 9 days. In endoscopy, the rate of cicatrisation of che day is 79.55%, in which, good cicatrisation is 54.28%. In pathological anatomy, the che day is effective in eridicating HP with the rate of 42.5 %; The rate of recovery is 23.25% and che day has no side effects.

Background: Vietnam is located in the endemic region of hepatitis B virus (HBV) infection, but no data of occult HBV infection was reported at present. Objectives: To investigate the prevalence of occult HBV infection in different ethnics of people and generations. Subjects and method: 80 voluteers with HbsAg negative from five different ethnics: Kinh, Tay, Mong, Giay and Dao in a Chino \ufffd?Vietnamses border province (Lao Cai) were enrolled in the study. After HBV-DNA was extracted, nested PCR of S gene and of Core-promoter/Pre-core region were used to detect HBV-DNA. Specifying nucleotide sequence was confirmed by direct sequencing. Results:The prevalence of occult HBV infection in population study was very high 73/80 (91,3%) by nested PCR of Core-promoter/Pre-core, significantly more sensitive than nested PCR of S gene (26,3%) (p<0,0001). The prevalence of occult HBV infection was notdifferent between ethnics of people or between children, adults. Conclusion: Occult HBV infection in Vietnamese is very common; however, nationwide further studies should be carried out to confirm this preliminary results and evaluate the impact of occult HBV infection in Vietnam.

Background: Hepatitis B is an infectious illness caused by hepatitis B virus (HBV) which infects the liver of hominoidea, including humans, and causes an inflammation called hepatitis. Objectives: The aim of study is to clarify clinical features and molecular characteristics of HBV in chronic HBV-infected patients with A 1899 mutation. Subjects and method: HBV genotype, HBV-ONA level, HBeAg and anti-HBe in 29 chronic HBV-infected patients were determined by PCR-RFLP, Real-time PCR and ELISA, respectively. Mutations were analyzed by direct sequencing. Results: Mutations in core-promoter/precore regions of HBV genome can suppress HBeAg secretion and stimulate HBV-ONA replication. The prevalence of hepatocel- lular carcinoma (HCc): 10/29, liver cirrhosis (LC) : 15/29 are significantly higher than that in chronic hepatitis (CH) : 4/29 (P < 0.001). HbeAg seroconversion rate in CH (75%) is higher than that in HCC \r\n', u'(40%) and in LC (53.3%), but not significant (P > 0.05). ALT level is the highest in CH and the lowest in HCC \r\n', u'(P = 0.02), 8/10 (80%) HCC patients have normal range of ALT. HBV-ONA level in HCC and in LC is significantly higher than that in CH (P = 0.024). The emerging of A 1899 is often accompanied by C/G1753 mutation (37.9%) and dual core-promoter mutation T1762A1764 (79.3%). Conclusion: A1899 mutation can play a role in the pathogenesis of liver diseases in chronic HBV-infected Vietnamese.\r\n', u'

Background: Hepatocellular carcinoma (HCC) is the most common primary hepatic tumor and one of the most common cancers worldwide. HCC is a primary malignancy of hepatocellular origin. Objectives:The aim of study is to combinate therapy of transarterial chemoembolization and percutaneousethanol injection afterward emerging metatasis caused by fine needle aspiration cytology. Subjects and method: A 50 years old male patient with hepatocellular carcinoma having a diameter of tumor more than 5 cm was treated by combination of transarterial chemoembolization and percutaneous ethanol injection from December 2000. Results & Conclusion: Results of study showed that: Transarterial chemoembolization and percutaneous ethanol injection are the two of non-surgical methods for treatment of hepatocellular carcinoma which are most commonly available in applied clinical activities at present. Up to now, the patient's life expectancy after therapy is more than 6 years that means the result of treatment is very good. However, the emerging metatasis into the anterior-right-Iower chest wall that was caused by fine needle aspiration cytology should be reviewed for further evaluating clinical experience, especially in cases with quite clear imaging features of untrasonography and significantly elevated AFP level higher than 200 ng/rnl.
