Studying the therapeutic effects of the traditional remedy of "tu than hoan" in the treatment of irritable bowel syndrome of diarrhea state

Background: Irritable bowel syndrome is a diagnosis of exclusion. It is a functional bowel disorder characterized by chronic abdominal pain, discomfort, bloating, and alteration of bowel habits in the absence of any detectable organic cause."Tu than hoan" is a traditional remedy applied for the treatment of syndromes of traditional medicine which have the similar characteristics to irritable bowel syndrome of diarrhea state of modern medicine. Objectives: The study had two purposes: (1)To evaluate the therapeutic effects of the remedy on the clinical symptoms of patients with irritable bowel syndrome of diarrhea state comparing with Duspatalin; (2)To evaluate the side effects of the remedy. Subjects and method:162 patients diagnosed with irritable bowel syndrome of diarrhea state were treated at Bach Mai hospital from March to August 2005. They divided into 2 groups, the control group included 77 patients and the study group included 85 patients. : clinical test, comparing with controls. Results: 80% of patients recovered from diarrhea; 82.4% of patients with defecation returned to normal; 93.6% stopped mucous feces; 76.5% stopped bellyache. Good therapeutic effect was 61.2% (p < 0.05). Conclusions: Tu than hoan had good therapeutic effects in the treatment of irritable bowel syndrome of diarrhea state. None of patients had to discontinue the medicine due to side effects. \r\n', u' \r\n', u'

Evaluating clinical experience from a case of hepatocellular carcinoma with combinated therapy of transarterial chemoembolization and percutaneousethanol injection afterward emerging metatasis caused by fine needle aspiration cytology

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.

Clinical characteristics and molecular characteristics of\r\n', u'hepatitis B virus in chronic hepatitis B virus infected patients\r\n', u'with A1899 mutation in precore region\r\n', u'

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'
