Background: The change of blood pressure during hemodialysis has been noted for long time. However, there were few studies on the rise of blood pressure during hemodialysis. The clinical meaning of hypertension during hemodialysis has not been understood clearly. Objective: To study the role of calcium concentration in dialysate in the rise of blood pressure during hemodialysis sessions. Subjects and method: Prospective study performed on 9 stable patients on chronic hemodialysis treated at Viet Duc Hospital including 5 female and 4 male patients. The mean age of patients was 47.6 years. The patients had period 1 of 10 weeks of treatment using dialysate 1 A (with calcium concentration 1.8 mmol/l) and then they were switched to period 2 of 10 other weeks using dialysate 3A (with calcium concentration 1.25 mmol/l). Results:The blood pressure of patients during the period 2 using 3A dialysate was better controlled during hemodialysis sessions. The response to erythropoietin treatment was similar in both periods. The serum calcium was lower after using 3A dialysate. Conclusions: Using dialysate with lower calcium concentration can be helpful for controlling the hypertension during hemodialysis sessions. The appropriate calcium concentration in dialysate needs to be selected to avoid the hypocalcaemia in chronic hemodialysis patients.

Background: Fragile X Syndrome (FXS) is the second cause of Mental Retardation (MR) and the first cause of familiar MR. This syndrome affects up to 1/4000 men and 1/8000 women. X syndrome is often diagnosed by molecular biology technique such as RCR and Southern blot. Until now there is no study on FXS in Vietnam. Objectives: This study is aimed at: (1) Determine FXS among children with MR by technique of molecular biology. (2) Determine the mutation of FMR1 gen in families having children with FXS. Subject and Method: 214 children between 6 and 16 years of age (136 male and 78 female) with MR were analyzed FMR1 gen by PCR and Southern blot techniques. Families of children with FXS were also analyzed. Result and conclusion: This is the first study on FXS using the techniques of molecular biology in Vietnam. Identified 3 children with FXS, accounting for 1.4% of MR. Children with FXS and members with full mutation and premutation were found.

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: Mental retardation is a common pathological state in children, accounting for about 1 - 3%. Children with mental retardation should have a life of integrity and proper support. The discovery and assessment the children will help us to orient the education, assistance and early intervention for them at each location. Objectives: This study aimed at determining the prevalence of mental retardation (MR) among children in some quarters and communes of Hue city and the degrees of mental retardation in these children. Subjects and method: Screening by WHO questionnaire \u201cTen Question screen for disability\ufffd?and learning results (if possible) of children from 6 to under 16 years old in 5 quarters (urban) and 2 communes (rural) randomly selected in Hue. Diagnostics and evaluations are based on the criteria of ICD \ufffd?10. Results: The prevalence of MR in this study was 0.94% (95%CI = 0.82 \ufffd?1.07), 1.18% in rural area and 0.84% in urban area; 1.16% among boys and 0.70% among girls. Mild MR accounts for 62.67% moderate: 19.36%, severe: 11.52% and profound: 6.45%. Conclusion: The prevalence was statistically significant higher in rural area than in urban area and in boys than in girls. There were predominant percentages of severe and profound MR.

Background: Heparansulfate Interacting Protein (HIP) is a protein that belongs to a novel class of heparin and heparansulfate binding protein. It plays an important role in extracellular matrix structure and function, cell-cell and cell-extracellular matrix adhesion, growth and differentiation. HIP was shown to be expressed in normal epithelia and epithelial cell lines at both mRNA and protein levels. Especially, HIP was found to be up-regulated in some cancer cell lines and related to different status and metastasis.\r\n', u'Objectives: To determinate HIP transcript level of mRNA in breast cancer tissues in comparison with normal tissues; to compare HIP transcript level at different cancer stages and cancer cell types. \r\n', u'Subjects and method: Total RNA was isolated from 62 tissue samples (47 breast cancer and 15 normal tissues); cDNA synthesis by reverse transcript \u2013polymerase chain reaction (RT \u2013 PCR); determination of HIP transcript using semi-quantitative RT \u2013 PCR. \r\n', u'Results: HIP transcript was particularly up \u2013 regulated in breast cancer tissues compared to normal tissues, especially this up-regulated in cancer tissues at different stages of development and cancer cell types. \r\n', u'Conclusion: These results show that the HIP transcript level was different between breast cancer and normal tissues and its expression was related to different status and metastasis in human cancer cell lines.
