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

0.05).CONCLUSION: The high expression of GPC3 mRNA in hepatocellular carcinoma is independent to the gene mutation,and to the expression of P53 and PCNA protein.

Objective The aim of this phase Ⅱ study was to determine the efficacy and safety of combined bortezomib and thalidomide (VT) regime as initial treatment for newly diagnosed multiple myeloma (MM) in China. Methods Thirty-four patients were enrolled in this study and received VT regime up to 21-day cycles. Bortezomib (1.3 mg/m2) was administered intravenously on days 1, 4, 8, and 11, while oral thalidomide ( 100 mg/day) was given from days 1 to 21. The primary end point was clinical response.The secondary end point was safety. Results Among the 34 patients, 20 were male, 14 were female, with a median age of 59 years, and 15 in international stage system (ISS) Ⅲ ,18 in ISS Ⅱ , 1 in ISS Ⅰ . Among them, 28 completed 2 cycles' treatment and achieved an overall response rate (ORR) of 92.9%; 26 were able to complete the planned 8 cycles of therapy. After 8 cycles, the ORR was 100% ( complete response 30. 8%, near-complete response 23.1%, partial response 42. 3%, minimal response 3.8% ). After followed up with a median time of 12 months, the estimated rate without progress of disease was 62%, and the estimated continous remission rate of 12 months was 62%. The median survival time was not achieved. The most common adverse events were mild to moderate ( grades 1, 2). The main toxicities were hematologic (53. 3% ), gastrointestinal ( 40. 0% ), peripheral neuropathy ( 38.0% ), fatigue ( 36. 6% ) and fever (32. 0% ). Conclusions VT regime provides a very high ORR and complete response rate in the treatment of newly diagnosed MM patients. No patients experienced deep venous thrombosis. In conclusion,bortezomib in combination with thalidomide is a very effective regimen for newly diagnosed MM patients and the toxicities are manageable.

Objective To explore the effects and mechanisms of prostaglandin E2 (PGE2) receptor 1 antagonist (SC-19220) on proliferation,prostaglandin synthase and extracellular regulated protein kinases (ERK) signal pathway induced by transforming growth factor β1(TGF-β1) in glomerular mesangial cells.Methods Mouse glomerular mesangial cells (GMCs) were divided into 5 groups:control group,TGF-β1 (10 μg/L) group,TGF-β1 (10 μg/L) plus SC-19220 group (0.1,0.5,1.0 μmol/L).The proliferation of GMCs was measured by CCK-8.The PGE2 in supernatant was measured by ELISA.The expression of connective tissue growth factor (CTGF),laminin (LN),cyclooxygenase 2(COX2),membrane-bound prostaglandin E2 synthase 1 (mPGES1) protein and mRNA was examined by Westem blotting and real-time quantitative PCR,ERK1/2 or phospho-ERK1/2 was measured by Western blotting as well.Results TGF-β1 induced the proliferation of GMCs and increased the secretion of PGE2.Besides,TGF-β1 significantly up-regulated the expression of CTGF,LN,COX2 and mPGES1 mRNA and protein (P ＜ 0.05),and increased the expression of phospho-ERK1/2 protein (P ＜ 0.05).However,SC-19220 significantly attenuated the changes of above-mentioned parameters and their activities (P ＜ 0.05).All the effects of SC-19220 were in dose-dependent manner.Conclusions SC19220 may reduce TGF-β1-induced cell damage by suppressing the activity of ERK1/2,and feedback inhibition of COX2,mPGES1 and PGE2,thus decreases the expression of LN and CTGF.

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.
