OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.
METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.
RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).
CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

Objective To study the life quality of 2 - 3 years old survivors in Neonatal Intensive Care Unit (NICU). Methods Severe neonates were randomly assigned to intervention group (group 1,30 cases) and non- intervention group (group 2,30 cases) depending on the early intervention applied or not,as well as 30 healthy newborns as normal controls. The physical,neurological conditions and intelligence test were taken regularly. To investigate the psychological state, actions, temperament and family conditions when they were2-3 years old.Results Mental development index(MDI) and physical development index(PDI) in early interventional group were significant higher than those in group 2(P

Dengue virus (DENV) envelope [E] protein is the major surface protein of the virions that indued neutralizing antibodies. The domain III of envelope protein (EDIII) is an immunogenic region that holds potential for the development of vaccines; however, the epitopes of DENV EDIII, especially neutralizing B-cell linear epitopes, have not been comprehensively mapped. We mapped neutralizing B-cell linear epitopes on DENV-1 EDIII using 27 monoclonal antibodies against DENV-1 EDIII proteins from mice immunized with the DENV-1 EDIII. Epitope recognition analysis was performed using two set of sequential overlapping peptides (16m and 12m) that spanned the entire EDIII protein from DENV-1, respectively. This strategy identified a DENV-1 type- specific and a group-specific neutralizing epitope, which were highly conserved among isolates of DENV-1 and the four DENV serotypes and located at two regions from DENV-1 E, namely amino acid residues 309-320 and 381-392(aa 309-320 and 381-392), respectively. aa310 -319(310KEVAETQHGT319)was similar among the four DENV serotypes and contact residues on aa 309 -320 from E protein were defined and found that substitution of residues E309 , V312, A313 and V320 in DENV-2, -3, -4 isolates were antigenically silent. We also identified a DENV-1 type-specific strain-restricted neutralizing epitope, which was located at the region from DENV-1 E, namely amino acid residues 329-348 . These novel type- and group-specific B-cell epitopes of DENV EDIII may aid help us elucidate the dengue pathogenesis and accelerate vaccine design.

Objective To examine mycological profile of eryptococcal meningitis in patients with non-acquired immune deficiency syndrome (AIDS) during treatment and follow-up so that to support clinical therapy. Methods Data of 28 cuhure-confirmed cryptoeoccal meningitis patients with non-AIDS were retrospectively analyzed. Fungat smear, count, culture and latex agglutination test of cerebrospinal fluid (CSF) were done during treatment and follow-up. Initial treatment included intravenous amphotericin B plus oral flucytosine or f;uconazole for at least 6 weeks, and consolidation treatment included oral fluconazole and (or) itraeonazole for at least 2 months. All 28 patients were cured. The data were analyzed by rank-sum test. Results The positive rate of CSF fungal smear was 92.9% before treatment and gradually decreased, and the fungal count was significantly reduced over time after treatment. While fungal smears of some patients were still positive after initial treatment. Fungal growth time in culture was gradually extended, and fungal culture turned to be negative in all patients after 2 weeks of treatment. The positive rate of latex agglutination test of CSF was 100%. Cryptococcal antigen titer decreased steadily after treatment, which was not correlated with the decrease of fungal count. Conclusion Mycological tests of patients with eryptococcal meningitis should be interpreted comprehensively during treatment, and result of each test should be specifically analyzed.

In this study,DNA molecular identification technology and chemical fingerprint method were adopted to evaluate the quality system of precise powder decoction pieces (PPDP) of S.suberectus dunn (SSD).ITS2 sequence was taken as DNA barcode to indentify SSD.Different specifications of PPDP were prepared,their dry extract contents were quantified in contrast with that of original slices.Three batches of SSD original slices were gleaned and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were valued by HPLC-DAD.As a result,ITS2 successfully and accurately identified the SSD in this study.The extract rate of PPDP was 15.5%,1.11 times as much as the original slices.RSD of inter-assay dissolution of cepicatechin from the original slices was 11.0%,which was reduced to 1.0% after mixing and preparing into PPDP.The relative peak area of the 14 common peaks identified by fingerpringts were larger,while the RSD values significantly decreased.It was concluded that the PPDP of SSD improved the extraction efficiency and uniformity of the original slices,featuring quite prospective in more reasonable and scientific clinical use.
