Objective To observe the curative effect and recurrence rate of desmopressin acetate(DDAVP) combined with bladder training therapy on primary nocturnal enuresis(PNE) in chlidren.Methods One hundred children with PNE were randomly divided into control group and observation group(50 cases in each group).Children in control group were treated with simple DDAVP,and patients in observation group were treated with bladder training while DDAVP was using.The course of treatment were 3 months.The therapeutic effect between the 2 groups when the treatment was finished was compared and then followed up all the cases for 3 months to compare the near-term and long-term recurrence rate between the 2 groups.SPSS 13.0 software was used to analyze the data.Results The total effective rate in control group was 72.9%,and the near-term recurrence rate and the long-term recurrence rate were 22.9% and 54.3%,respectively.The total effective rate in observation group was 91.3%,and the near-term recurrence rate and the long-term recurrence rate were 11.9% and 28.6%,respectively.The total effective rate was significantly higher in observation group than that in control group(Z=-1.972,P=0.049).The near-term recurrence rate in 2 groups had no significant difference(?2=1.632,P=0.201).The long-term recurrence rate was extremely lower in observation group than that in control group(?2=5.249,P=0.022).Conclusions There is significant curative effect that DDAVP combined with bladder training therapy on PNE in children,and it can lower the long-term recurrence rate.

Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

OBJECTIVETo evaluate the significance of quantification of WT1 mRNA for monitoring minimal residual disease (MRD) in patients with acute myeloid leukemia (AML).

METHODSWT1 mRNA level was detected with real-time quantitative RT-PCR (RQ-PCR) technique in bone marrow samples from 15 normal subjects (NBM) and 123 AML patients. Sixty-two AML samples were also detected AML1-ETO mRNA expression by RQ-PCR. Simultaneously follow-up of WT1 and AML1-ETO levels were carried out in 50 samples from 8 AML patients. WT1 and AML1-ETO levels were normalized by internal control ABL gene.

RESULTSAll correlation co-efficiencies were over 0.99 for WT1, AML1-ETO and ABL standard curves. Co-efficiencies of both interassay and intraassay variation were below 4%. The WT1 expression levels in NBM were 0.001 to 0.019 with a median level of 0.008. Higher levels of WT1 expression were found in 61 of 67 (91%) newly diagnosed AML patients compared with NBMs and 37 of the 67 (55.2%) showed 100-fold higher WT1 levels than that in NBMs. WT1 mRNA levels were highest in M(4EO) and M(3) and lowest in M(1) and M(5) patients. There was an excellent correlation between WT1 and AML1-ETO gene expression levels (r = 0.88, P < 0.001). WT1 expression levels in three patients who were in continuous complete hematological remission (CHR) were within normal range. In three of four relapsing patients, WT1 expression levels increased 31.4, 11.4 and 4.0 fold respectively one month before hematological relapse.

CONCLUSIONSQuantification of WT1 expression level by RQ-PCR may be used to monitor MRD for most AML patients, but it is less sensitive than fusion gene. Continuous or significant increase of WT1 expression in CHR patients predicts an impending relapse.

OBJECTIVETo compare the immunophenotypic and clinical characteristics between NPM1 mutated acute myeloid leukemia (AML) (NPM1m(+)AML) and unmutated AML(NPM1m(-)AML) not otherwise characterized (NOS) under similar FAB subtypes constituent ratio.

METHODSImmunophenotyping and NPM1 gene mutation type-A, B and D and other leukemic related fusion genes were detected by multiparameter flow cytometry and real time RT-PCR or PCR, respectively. 104 AML patients with NPM1m(+)AML and performed immunophenotyping assay were included, 97 with NPM1m(-)AML.

RESULTSThere were significant difference between the two groups at presentation in terms of sex, white blood count(WBC), platelet counts (PLT), blast ratio, normal karyotype ratio, WT1 expression level, FLT3-ITD mutation positive rate and remission rate of first course of induction therapy (P < 0.05). On the immunophenotype, the expression of early differentiation antigens (CD34, HLA-DR, CD117, CD38), lymphocytic antigens (CD7, CD4, CD19, CD2), myeloid and monocytic differentiation-associated antigens (CD13, CD14, CD15) were lower, and that of CD33 as well as CD123 were higher in NPM1m(+)AML patients. Among them, only CD34, HLA-DR, CD7, and CD4 positive cases were significantly lower in NPM1m(+)AML group than in NPM1m(-)AML group (P < 0.05), the rest of them had significant difference in the number of positive cells (P < 0.05). Above features were further analyzed between the M1/M2 and M4/M5 subgroups. M1/M2 cases retained the women prominent and had a higher WT1 expression level (P < 0.05). The expression of monocytic differentiation-associated antigens including HLA-DR and lymphocytic antigens were higher and that of CD117 were lower in M4/M5 subtype (P < 0.05). Among them, the positive rates of HLA-DR, CD64, CD11b, CD10, CD15, and CD4 were significantly higher in M4/M5 than in M1/M2 in NPM1m(+)AML group (P < 0.05).

CONCLUSIONThe most clinical characteristics in NPM1m(+)AML patients are consistent with reports, but some immunophenotype are different to the previous reports under similar FAB subtypes constituent ratio. The major immunophenotypic features of NPM1m(+)AML patients are lower expression of progenitor, myeloid and lymphoid lineage antigens. Monocytic differentiation-associated antigens are only higher expression in M4/M5 cases when comparison with M1/M2 cases within NPM1m(+)AML group.

OBJECTIVETo investigate the effects of sodium alginate gels on marrow mesenchymal stem cell transplantation for repair of spinal cord injury (SCI) in mice.

METHODSIn the present study, effects of different sterilization methods and concentrations of sodium alginate gels were examined. Marrow mesenchymal stem cells (mMSCs) were isolated from mice and cultured. Cells were cultured with sodium alginate gels and MTT assay was applied to determine the cell viability. Mice spinal cord injury was induced by spinal cord transection. mMSCs were transplanted into the cavity of injured spinal cord with sodium alginate gels. The effects of sodium alginate gel were assessed by BMS scales and immunofluorescence staining for NF-200.

RESULTSCompared with liquid form, solid form sodium alginate gel prepared with high pressure vapor sterilization had a better effect on cell viability. SCI mice treated with 10 % sodium alginate gel and mMSCs achieved higher score in BMS scale as well as higher expression of NF-200 compared with the untreated SCI group.

CONCLUSIONSodium alginate gel prepared with solid form sterilization induces mMSCs proliferation and thus can be used as the carrier of stem cell in treatment of SCI.

This study was purposed to investigate the effect of adenovirus-mediated transfer of PDCD5 gene on apoptosis of K562 cells induced by etoposide. Recombinant adenovirus PDCD5 (Ad-PDCD5), control vectors Ad-null and Ad-eGFP were constructed by AdMax vector system respectively. After K562 cells were transfected by Ad-PDCD5, Ad-null or Ad-eGFP with different multiplicity of infection (MOI), the expression level of the PDCD5 gene was examined by RQ-RT-PCR assay. The effects of etoposide in combination with Ad-PDCD5 on the proliferation and apoptosis of K562 cells were measured by using MTT assay and flow cytometry with Annexin-V-FITC/PI dual labeling technique, respectively. The results showed that the transfection efficiencies of Ad-eGFP in K562, Jurkat and CEM cells ranged from 60% to 86%. Expression level of PDCD5 gene in K562 cells was evidently increased following transfection with Ad-PDCD5. The Ad-PDCD5 synergistically enhanced the apoptotic percentage of K562 cells induced by VP-16, as compared with that of Ad-null + VP16 and VP-16 alone respectively. It is concluded that Ad-PDCD5 may be a potential agent for enhancing the chemotherapy effect.

OBJECTIVETo evaluate levels of common specific fusion transcripts M-bcr-abl, m-bcr-abl, TEL-AML1, AML1-ETO, PML-RAR alpha, CBF beta-MYH11 in untreated leukemia patients.

METHODSSpecific fusion transcript levels were detected by TaqMan-based real-time quantitative RT-PCR technique in a total of 208 samples, including 195 bone marrow samples from 50 M-bcr-abl(+) chronic phase-chronic myeloid leukemia (CML-CP), 10 M-bcr-abl(+) acute lymphoblastic leukemia (ALL), 19 m-bcr-abl(+) ALL, 11 TEL-AML1(+) ALL, 30 AML1-ETO(+) acute myeloid leukemia (AML), 58 PML-RAR alpha(+) acute promyelocytic leukemia (APL) and 17 CBF beta-MYH11(+) AML patients and 13 peripheral blood samples from 13 M-bcr-abl(+) CML-CP patients. abl was chosen as internal control gene. Fusion transcript level was calculated as fusion transcript copies/abl transcript copies in percentage.

RESULTSBone marrow and peripheral blood samples of CML-CP patients had similar M-bcr-abl fusion transcript levels (median 30% vs 35%, P > 0.05). M- and m-bcr-abl (median 64% vs 54%) levels were similar in ALL patients (P > 0.05), M-bcr-abl level was significantly higher in ALL than CML-CP patients(P < 0.001). Median TEL-AML1 level was 228% in ALL patients. Among AML patients, AML1-ETO level was significantly higher than CBF beta-MYH11 and PML-RAR alpha levels (median 388% vs 145%, 388% vs 47%, all P < 0.001), CBF beta-MYH11 level was significantly higher than PML-RAR alpha level (P < 0.001). Fusion transcript levels of L-, V- and S-type PML-RAR alpha were 45%, 44% and 55%, respectively. L-type was significantly lower than S-type (P = 0.04).

CONCLUSIONSFusion transcript levels in untreated leukemia patients were different and patient-to-patient variations did exist. Detection of fusion transcript levels in untreated leukemia patients not only provides baseline for minimal residual disease monitoring and treatment evaluation but also enable the comparison in inter-laboratory data.
