Background: Fragile X Syndrome (FXS) is the most common cause of inherited mental retardation. The absence of Fragile X Mental Retardation (FMRP) in Fragile X syndrome changes other proteins. Objective: To detect changes of glycoprotein in human serum of Fragile X syndrome. Subject and methods: Affinity chromatography with lectin concanavalin A (ConA) used to receive glycoprotein. The collected glycoprotein was then separated using 2-D electrophoresis. The protein spots were further excised, trypsin digested, and analyzed by nano LC couple with ESI-MS/MS and identified by MASCOT v1.8 software. Results and conclusion: 5 glycoproteins showed the different expression levels in the serum of Fragile X syndrome. Haptoglobin, Ig-J were increased and ceruloplasmin, transferring, Ig kappa were decreased. Using affinity chromatography with lectin concanavalin A (ConA), glycoprotein was received and divided on 2 ways electrokinetic chromatography. The mixture protein was identified with a reliability of 99.5% by 2 ways liquid chromatography combined with continuous spectrum mass.

Background: According to WHO, there are 5 million deaths from kinds of injury a year in the world, of which 875000 deaths occur in children under 18 years old. Injury leads to 40000 deaths which account for 10.7% deaths due to all other causes a year in VietNam. Objective: To show conclusions of the situation of child injury, recommendations for prevention of child injury and methods in order to enhance emergency activity in Vietnam. Subjects and method: The authors collected information about all patients who had emergencies due to injury at Viet Duc hospital, from March 26th 2006 to Octorber 26th 2006. However, supervised cases were the patients under 18 years old who were examined and treated at the Department of Emergency. Results: During the period of study, 2536 patients under 18 years old were examined for injury, of which death and coming back home for death were 83 cases (3.27%). 974 children had emergency resulted from injury: male was more than female: 697 verus 227. The leading causes of child injury were fall and traffic accident, respetively 34% and 60%. The most common traumas were traumatic brain injury (45%), limbs injury (41%). Although most of cases had first aid at the hospitals in district or province level, the rate of non-first aid cases was high (34%). Conclusion: Child injury is a leading cause of child death in hospitals. Methods for prevention of child injury should focus on educating and propagandizing to minimize injuries caused by traffic accident and fall.

Objective: The purpose of this survey was to estimate the prevalence of viral load (VL) suppression and emergence of HIV drug resistance (HIVDR) among individuals receiving antiretroviral therapy (ART) for 36 months or longer in Viet Nam using a nationally representative sampling method. Methods: The survey was conducted between May and August 2014 using a two-stage cluster design. Sixteen ART clinics were selected using probability proportional to proxy size sampling, and patients receiving ART for at least 36 months were consecutively enrolled. Epidemiological information and blood specimens were collected for HIV-1 VL and HIVDR testing; HIVDR was defined by the Stanford University HIVDR algorithm. Results: Overall, 365 eligible individuals were recruited with a mean age of 38.2 years; 68.4% were men. The mean time on ART was 75.5 months (95% confidence interval [CI]: 69.0–81.9 months), and 93.7% of the patients were receiving non-nucleoside reverse transcriptase inhibitor-based regimens. Of the 365 individuals, 345 (94.7%, 95% CI: 64.1–99.4%) had VL below 1000 copies/mL and 19 (4.6%, 95% CI: 2.8-–7.5) had HIVDR mutations. Discussion Our nationally representative survey found a high level of VL suppression and a low prevalence of HIVDR among individuals who received ART for at least 36 months in Viet Nam. Continued surveillance for HIVDR is important for evaluating and improving HIV programs.
