Bacillus are well known antibiotic producers. In this study,dozens of Bacillus strains from different sources were screened. Among them,a strain with strong antifungal activity was found. With 16S rDNA test and Biolog assay,this strain was identified to be Bacillus amyloliquefaciens. The fermentation conditions were optimized in small conical flasks. After ammonium sulfate salting out,dialysis,freezing vacuum dehydration,the crude protein extracts were obtained. The thermal stability,pH stability,protease stability,ion stability and antifungal spectrum of this protein were studied further. Scanning electronic microscope was also used to explore the antifungal mechanism.

OBJECTIVETo evaluate the therapeutic effect and safety of pelvic methotrexate (MTX) injection via the posterior fornix for treatment of tubal pregnancy.

METHODSNinety-six patients with tubal pregnancy (mean age 21-40 years) were randomized into 3 groups for treatment with pelvic MTX injection via the posterior fornix+mifepristone+traditional Chinese medicine (experiment group), intramuscular MTX injection+mifepristone+traditional Chinese medicine (control group I), or mifepristone+traditional Chinese medicine (control group II). On days 4 and 7 of the treatment, blood β-HCG of the patients in different groups was detected, and in cases with continuous reduction of blood β-HCG or a reduction by over 15%, β-HCG was checked every week. One week after the treatment, the size of the mass was measured by B-mode ultrasound. The clearance time of β-HCG and the hospital stay of the patients were recorded.

RESULTSTwenty-nine patients in the experimental group were treated successfully, with a cure rate of 90.6%, which was significantly higher than those in the two control groups (P<0.05). The clearance time of β-HCG and hospital stay were also much shorter in the experimental group (P<0.05).

CONCLUSIONPelvic MTX injection via the posterior fornix is a convenient procedure associated with minimal complications and serves as a good alternative for treatment of tubal pregnancy.

OBJECTIVETo locate the cluster region of loss of heterozygosity (LOH) in children with acute lymphoblastic leukemia (ALL), and explore the new tumor suppressor gene.

METHODSAllelic loss was analyzed by PCR with 15 microsatellite markers mapping on 6q16.3. The LOH was analyzed by bioinformatics. The relationship between LOH and clinical factors was further analyzed.

RESULTSThe frequency of LOH at least at one loci on 6q16.3 was 32.7%. The LOH in relapsed patients was higher than those in not relapsed. The higher frequency of LOH was observed in two regions of D6S1709-D6S1028 and D6S2160-D6S1580 at 6q16.3. GRIK2 may be a candidate of tumor suppressor gene. There are 12 ESTs may carry out new anti-oncogene. Patients with 6q LOH had higher WBC counts (P < 0.01), blast cells percentage (P < 0.01), relapse rate (P < 0.05) and chromosomal aberration (P < 0.05).

CONCLUSIOND6S1709-D6S1028 and D6S2160-D6S1580 are two regions of minimus deletion on 6q16.3 in which tumor suppressor gene may exist. The LOH on 6q16.3 may be a prognostic index of children with ALL.

Objective To evaluate the effect of health education during pregnancy with analgesic delivery on the rate of cesarean section.Methods A total of 320 primipara with no high-risk pregnant factors in the outpatient service of gynecology and obstetrics were enrolled.They were randomly divided into intervention group and control group with 160 cases for each group.The intervention group accepted individual health education interventions and analgesic delivery,while control group received routine pregnancy examine and guidance.Then,the delivery way and the incidence of fetal macrosomia,fetal distress and so on were observed of two groups.Results The cesarean section rate of intervention group was 16.25％,and that of control group was 63.13％,and the difference was statistically significant (x2 =73.436,P ＜ 0.05),and the rate of cesarean section with medical index and no in intervention group respectively were16.17％ and 0.00％,and that of control group respectively were 28.12％ and 35.00％,and the difference was statistically significant (x2 =67.879,6.534,respectively ;P ＜ 0.05).Conclusions The implementation of health education with analgesic delivery may be effective to reduce the rate of cesarean section.

OBJECTIVEMultidrug resistance (MDR) is one of the primary causes of suboptimal outcomes in chemotherapy of children with acute myeloblastic leukemia (AML). The mechanisms of drug transport resistance may chiefly contribute to MDR. Expression and/or activity of P-glycoprotein (P-gp), multiple resistance-associated protein-1 (MRP1), lung-resistance related protein (LRP) and breast cancer resistance protein (BCRP) have been considered to be associated with unfavourable outcomes in pediatric AML patients. In previous studies, we found WASP-family verprolin-homologous protein-1 (WAVE1) was involved in the MDR mechanisms in K562/A02 leukemia cells. To investigate the expression of WAVE1, P-gp, MRP1, LRP/MVP and BCRP; and if WAVE1 is involved in MDR of human leukemia cell.

METHODSWAVE1, P-gp, MRP1, LRP, BCRP mRNA and protein expression in bone marrow mononuclear cells (BMMCs) were measured by real-time fluorescence quantitative PCR (RQ-PCR) and Western blot in a cohort of 52 children with acute myeloblastic leukemia. During follow-up, of the 52 patients, 21 were documented as being relapsing or refractory, and 31 were induced into complete continuous remission. Furthermore, HL60 cells and HL60/ADR cells were transiently transfected with PCDNA3.1-WAVE1 reconstructed plasmid and specifically siRNA to WAVE1 respectively, and the expression of WAVE1, MRP1 and BCRP before and after transfection was assessed by real-time PCR and Western blot analysis.

RESULTS(1) The expression levels of WAVE1, P-gp, MRP, LRP and BCRP in refractory/relapsing group were much higher than that in complete continuous remission (CCR) group. (2) WAVE1 mRNA and protein expression in BMMCs of children were at higher levels when they were newly diagnosed or relapsed, compared with complete continuous remission. (3) The WAVE1 expression at mRNA and protein level in HL60/ADR cells was increased by about 353% and 95% respectively as compared with that in HL60 cells. (4) Overexpression of WAVE1 in HL60 cell lines upregulated the expression levels of MRP and BCRP (MRP mRNA and protein level were increased by about 16.54 times and 129% respectively, BCRP was increased by 4.93 times and 96%); whereas suppression of WAVE1 expression by RNA interference downregulated the expression levels of MRP1 and BCRP (MRP mRNA and protein level was only 11% and 43% of pre-disturbance respectively, BCRP was 14% and 71%).

CONCLUSIONSHigher levels of WAVE1 in the BM indicate an unfavorable prognosis in children with AML. WAVE1 is related to the development of AML and involved in the MDR mechanisms, and regulates the level of MRP1 and BCRP.

OBJECTIVETo evaluate the long-term efficacy of infant hepatitis B (HB) immunization program on preventing hepatitis B virus (HBV) infection, and to assess its impact on the incidence of HB in children.

METHODSSince 1986, the universal HB vaccination for newborn babies with standard, pediatric dose had been launched without serologic prescreening of pregnant women for HBsAg, in a high endemic county of Long-An. A hepatitis surveillance system was set up to evaluate the possible impact on the incidence of hepatitis B. To serologically evaluate the effectiveness of the program, a stratified random sampling of 1000 children in 1987 birth cohorts, who received plasma-derived HB vaccine, was recruited for long-term follow up at the age of 1 to 13 years. A cross-sectional seroepidemiological survey was conducted in the county in 1985, before the program, and in 2001, for 1551 children born in 1996-2000 who were administered yeast recombinant HB vaccine.

RESULTSDuring the 1 to 13 years after the program, the rates of HBsAg-positive were 0.7% to 2.9% with an average of 1.7% and the protective rates were 83.5% to 96.6%. HBV infection rates were 1.1% tp 5.1% with an average of 2.4% and the protective rates were 93.5% to 98.4%. For the population aged 1 to 4 years who were immunized with recombinant HB vaccine, HBsAg positive rates were 1.8% to 2.4% with an average of 2.0% and the protective rates were 78.4 to 85.2%. 14 years after the program, the cumulative incidence of acute hepatitis B in the children aged 1 to 14 years fell to 1.5 cases per 100,000 children, down 91.8% as compared with that in 1985 to 1987. However, the cumulative incidence of 14.4 cases per 100,000 population in unvaccinated children was not significantly different from that in the history controls. Acute hepatitis B children had not been reported, showing that the vaccination program was 100% protective in children.

CONCLUSIONThe universal infant HB vaccination program in a hyperendemic area has proved to be effective in controlling HBV infection and decreasing the incidence of acute hepatitis B in children. Booster dose is unnecessary in 13 years after the immunization. The protective efficacy of yeast recombinant HB vaccine is similar to that of plasma-derived HB vaccine.
