Objective To investigate the genotype and mutation frequency of thalassemia in child patients of Shenzhen region so as to provide evidences for the gene diagnosis and genetic counseling of thalassemia.Methods A total of 1 206 child patients suspected with thalassemia were retrospectively analyzed.The gene deletion of α-thalassemia was detected by Gap-PCR.The point mutations of α-thalassemia and β-thalassemia were determined by reverse dot blot(RDB)-PCR.The specimens suspected with HKαα and rare gene mutations were determined with nested PCR and gene sequencing,respectively.Results The detection rate of thalassemia was 76.9％ (927/ 1 206).Among them,α-thalassemia accounted for 40.5％ (489/1 206),and--SEA/αα was the most common gene mutation(75.1％);β-thalassemia accounted for 33.7％ (406/1 206),and the main IVS-2-654 (C→T) and CDM1-42 (-TCTT) heterozygous mutations accounted for 35％ and 32.5％,respectively.In addition,there were 32(2.7％) β-thalassemia patients with α-thalassemia mutation,1 patient with HKαα/ααQS,1 α-thalassemia patient with CD61 (AAG→TAG)/--SEA and 1 β-thalassemia patient with CD5 (CCT→C).Conclusion The are complicated gene mutation types and rare gene mutations of thalassemia in child patients of Shenzhen region.

Objective To investigate the effects of tongue cancer resistance-associated protein 1 (TCRP1) in proliferation of chronic myeloid leukemia cells (CML),and explore the new thoughts of pathogenesis of CML.Methods The expression of TCRP1 was detected in the peripheral blood mononuclear cells (PBMC) of CML with real-time quantitative polymerase chain reaction (PCR) and Western blot.After the expression of TCRP1 was interfered in K562 cells,the proliferation of cells was detected by 3-(4,5-dimenthylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay and soft agar colony forming assay,and the expression of protein kinase B (AKT) and its phosphorylation were tested by Western blot.Results In PBMC of CML patients,the mRNA and protein levels of TCRP1 were significantly higher than those of normal controls.The results of MTS assay and soft agar colony forming assay showed that the proliferation of K562 cells was significantly decreased after the expression of TCRP1 was interfered.After knockdown of TCRP1 in K562 cells,the phosphorylation of AKT was significantly decreased while the expression of total AKT did not change.Conclusions The expression of TCRP1 was increased in CML cells.High expression of TCRP1 might contribute to proliferation of K562 cells via the phosphorylation of AKT.

Objective The purpose of this study was to assess the analysis capabilities of the dot immunogold filtration method on detecting serum amyloid A ( SAA ) protein in blood.It also aimed to research the clinical value of SAA in diagnosing the infectious diseases of children .Methods ( 1 ) The performance evaluation including the accuracy , within-run precision, inter assay variations , the linear and the distraction-analysis of SAA-SPOT was estimated following the EP file; From March to July in 2014, children from five 3A Grade hospitals in Guangdong Province were enrolled into this observational study.Data including white blood WBC count , CRP and SAA were obtained.(2) From March to July in 2014, children from five 3A Grade hospitals in Guangdong Province were enrolled randomly into this observational study.This study used a cross-sectional survey research method , and 386 children with bacterial infection and 219 children with virus infection were as the research object.The general , clinical diagnosis , treatment information as well as the data of blood SAA , C-reactive protein ( CRP ) and white blood cell ( WBC ) of children were collected.Data were analyzed by variance , independent t test, ROC curve analysis and stepwise regression statistics method.Results ( 1 ) The average recovery rate is 103.74 %.Coefficient of variation (CV) for 10 mg/L,100 mg/L within-run assays were 8.77%, 3.61% and between-run assays were 9.01%, 3.74%;the inter-day CV were 9.07%, 4.03%respectively;the linear range was 5 mg/L-200 mg/L, hemoglobin(5 g/L),serum bilirubin(800 μmol/L),triglyceride(TG, 22 mmol/L), and had no interference in SAA detection.When compared to the BNPRO quantitate system of SIEMENS , the coefficient of association of detection of SAA by SAA-SPOT was R2 =0.96.( 2 ) Compared with control group , the serum SAA of infection group ( bacterial infection group , t =13.05, P=0.001;virus infection group t =7.68, P=0.001) and SAA/CRP ratio (bacterial infection group t=2.29, P=0.023;virus infection group t=3.32, P=0.01) were significantly increased.(3) The serum CRP and SAA rose similarly in bacterial infection, while in viral infection, only SAA increased significantly , CRP had no apparent change.In combination with CRP and WBC , SAA had the better diagnostic efficiency apparently.Conclusions As a POCT detection project , analysis capabilities of the SAA assayed by domestic SAA-SPOT can meet the requirements of clinical test.Combined with CRP , WBC and SAA can improve the efficiency in the diagnosing of infectious disease especially in the virus infection.As a new biomarker of infections , SAA is useful for the early auxiliary diagnosis and differential diagnosis of childhood infection.

OBJECTIVETo investigate the protective mechanism of stearoyl-CoA desaturase 1 (SCD1) over-expression against the pro-apoptotic affects of palmitic acid on hepatocytes using the rat BRL cell line.

METHODSConcentration effect curves were generated using the trypan blue exclusion test to assess the death rate of BRL cells upon exposure to a dilution series of palmitic acid. The multiplicity of infection (MOI) of a lentiviral expression vector, pGC-FU-GFP, was determined for the BRL cells. Unmanipulated BRL cells were divided into two groups: the non-palmitate groups were composed of ordinary cultured cells (CON) alone, infected with lentivirus empty expression vector (negative control, NC), and infected with lentivirus overexpressing SCD1 (SCD1-LV); the palmitate groups were composed of ordinary cultured cells plus palmitate (CON+) alone, infected with lentivirus empty expression vector plus palmitate (NC+), and infected with lentivirus overexpressing SCD1 plus palmitate (SCD1-LV+). SCD1 mRNA expression was detected by real-time PCR. Propidium iodide (PI) single-staining was used to detect apoptosis and assess the cell cycle. Inter-group differences were analyzed statistically.

RESULTSThe death rate of BRL cells increased significantly after 72 h of exposure to 400 mumol/L palmitate (P less than 0.01). The MOI of pGC-FU-GFP in BRL cells was 20. The expression of SCD1 was significantly higher in the SCD1-LV and SCD1-LV+ groups than in the respective controls (vs. CON: F = 289, P less than 0.01; vs. CON+: F = 1522, P less than 0.01). Palmitate exposure led to decreased expression of SCD1 (CON+ vs. CON, F = 22, P less than 0.05 and NC+ vs. NC: F = 34, P less than 0.05). The ratio of S stage cells was similar in all non-palmitate groups (CON, NC and SCD1-LV, P = 0.137). However, there was a significant apoptotic peak and lower ratio of S stage cells in the control palmitate groups (CON+ and NC+) and the activity of cell proliferation was decreased as well. The ratio of apoptotic cells was decreased significantly in the SCD1-LV+ group compared to the CON+ group (P less than 0.01).

CONCLUSIONThe expression of SCD1 and its desaturation activity increased in BRL cells upon infection with the pGC-FU-SCD1-GFP lentiviral vector, suggesting that SCD1 over-expression can decrease palmitic acid-induced toxicity and apoptosis in hepatocytes.
