Background: Deletion and duplication mutations of dystrophin gene make up from 70 to 75% of patients with Duchenne Muscular Dystrophy (DMD). Two thirds of children with DMD inherited from the heterozygous mothers the mutated gene which is located on one of the sex chromosomes. Objective: To detect the asymptomatic carriers of dystrophin gene mutation using molecular techniques. Subject and methods: 3 DMD patients and their 9 relatives. Using techniques: DNA extraction and quantitative Polymerase Chain Reaction (PCR). Results: Successfully detected 4 heterozygous individuals from 9 female members of three different families that have already confirmed DMD patients. Conclusion: This method could lead to a new way of prenatal diagnosis of DMD as well as other genetic disorders that are caused by deletion or duplication mutation.

Journal of Medical Research 2008;54(2):1-5
Background: Heparan-sufate interacting protetin (HIP) has been known to be up-regulated and expressed in various human cancer cell lines at both transcript and protein levels. HIP\u2019s expression was related to the differentiation status and cancer development. Objective: Using a semi-quantitative PCR method to determine HIP transcript levels in benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia (PIN) and prostate cancer tissues. Subjects and methods: 30 samples of BPH, 12 samples of high-grade PIN, and 40 samples of prostate cancer were collected from patients at Viet Duc Hospital and Friendship Hospital. Total RNA was extracted from BPH, PIN and prostate cancer tissues; cDNA synthesis by reverse transcript - polymerase chain reaction (RT - PCR); HIP transcript determination using semi-quantitative PCR. Results: There was significant difference in HIP transcript levels. HIP transcript was very highly up-regulated in the prostate cancer tissues. The up-regulation of HIP transcript was lower in PIN, and lowest in BPH. HIP transcript levels in benign samples were 1/2 and 2/3 compared with cancer and PIN samples, respectively (P< 0.05). These indicated that up-regulation of HIP transcript may be an early event in tumorigenesis. Conclusions: Levels of HIP transcript were different between tissues of prostate cancer, PIN, and BPH. HIP may be a marker for pre-cancer of the prostate.

Background: Heparansulfate Interacting Protein (HIP) is up-regulated in various human cancer cell lines at both transcript and protein levels. HIP expression is related to the differentiation status and cancer development. Objectives: To determine HIP in benign prostatic hyperplasia, prostatic intraepithelial neoplasia and prostate cancer tissues. Materials and method: Western blot method was used to determine HIP expression in 3 different types of prostate tissue, including 11 prostate cancer samples, 2 benign prostatic hyperplasia samples and 11 prostatic intraepithelial neoplasia samples. Results. HIP was particularly up-regulated in prostate cancer and prostatic intraepithelial neoplasia, indicating that up-regulation of HIP expression may be an early event in tumorgenesis. Conclusion: The expression of HIP was different between cancer, prostatic intraepithelial neoplasia tissue and benign prostatic hyperplasia. HIP may serve as a prognostic marker for prostate carcinoma.

Background: Bone marrow stem cells with their plasticity can be used to replace and repair the other damaged organs and tissues, so they can also be used to obtain bone healing of nonunions. Objective: to evaluate the results of percutaneous autologous bone marrow grafting to treat the tibia diaphyseal nonunions. Subjects and methods: 12 patients with noninfected nonunion of the tibia were diagnosed and treated in Viet Duc Hospital. About 250mL of marrow was aspirated, then separated and concentrated by density gradient centrifugation. The final mononuclear cell mass containing stem cells and progenitors was washed in 30ml of 0.9% NaCL and then injected into the damaged sites. Patients were evaluated by clinical and X-rays examinations with at least 6 months follow-up. Results: None of the patients had post - op complications. Bone union was obtained in eleven of the twelve patients (91,7%) at an average of 15,3 weeks (range, 9 - 30 weeks), the bone marrow grafts used for these patients who had bone union contained a mean of 5,65 \xb1 3,74 x 106 (0,95 - 11,73 x 106) CD34(+) stem cells in total. Conclusions: Percutaneous autologous bone - marrow grafting is a minimally invasive alternative and a simple, effective, safe method for the treatment of the tibia diaphyseal nonunions with the comparative bone healing rate. \r\n', u'\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.

Anaplasma marginale and A. platys were detected and characterized (16S rDNA sequence analysis) from dairy and indigenous cattle, and the latter in domestic dogs in Vietnam. A phylogenetic tree was inferred from 26 representative strains/species of Anaplasma spp. including 10 new sequences from Vietnam. Seven of our Vietnamese sequences fell into the clade of A. marginale and 3 into A. platys, with strong nodal support of 99 and 90%, respectively. Low genetic distances (0.2–0.4%) within each species supported the identification. Anaplasma platys is able to infect humans. Our discovery of this species in cattle and domestic dogs raises considerable concern about zoonotic transmission in Vietnam. Further systematic investigations are needed to gain data for Anaplasma spp. and members of Anaplasmataceae in animal hosts, vectors and humans across Vietnam.
