Objective To observe the changes of systolic time interval after neonatal asphyxia and explore its relationship with clinical manifestation and prognosis. Methods Tow-dimensional and Doppler echocardiography were employed to detect tow - dimension parameters and left and right ventricular STI in 27 mild and 18 severe asphyxiated neonates as well as 14 normal controls and its relationship with clinical manifestation and prognosis was analyzed. Results There was no difference in cavity and thickness of heart and great arteries between normal and asphyxiated neonates. In acute stage mild and severe asphyxiated neonates had a shorter right ventricular ejection time (RVET) than normal neonates and a longer right ventricular prejection period (RPEP) was found in severe neonates than that in normal and mild asphyxiated neonates. Left ventricular preejection time (LPEP) was prolonged in comparison with normal neonates in acute stage and convalescence. There were more cases with increased RPEP/RVET in severe asphyxiaed group than those in mild and normal group in acute stage. The incidence of heart failure in acute stage and disability in late period was higher in cases with increased RPEP/RVET than that with normal RPEP/RVET. Conclusion Asphyxia has more severe damage to right ventricle than that to left ventricle. Cases with increased RPEP/RVET are prone to suffering from heart failure in acute stage and more likely to undergo disability in late period.

Objective To investigate the effects of the HLA-Ⅰ and co-stimulators CD_(80)and CD_(86)on HT-29 cells surface, after heat killed Bifidobacterium and HT-29 cells were mingled culturing for 12 hours. Methods The HLA-Ⅰ and co-stimulators CD_(80)and CD_(86)on HT-29 cells surface were measured by Flow Cytometer. Results Heat killed Bifidobacterium can improve the expressions of HLA-1, CD_(80)and CD_(86)on HT-29 cells significantly, the livability of colon carcinoma cell was more than 90 %. Conclusion Heat killed Bifidobacterium have potential antitumorous features.

Objective To explore the relationship between cough variant asthma (CVA) and mycoplasma pneumoniae (MP) infection.Methods Fifty children with CVA were chosen as the experimental group at random,and 50 children with acute upper respiratory infection,who went to the hospital in the same time and with similar age,were chosen as control group.The MP-IgM of children in both groups were tested by the granule agglutinating method.Results Significant difference (? 2=9.013 P

Objective To examine the sensitivity of human glioblastoma multiforme cell line BT325 to 5 antineoplastic drugs, including cisplatin (DDP), teniposide (VM26), nimustine (ACNU), temozolomide (TMZ) and vincristine (VCR). Methods BT325 cells were incubated in DMEM with 10% or 20% fetal bovine serum (FBS) or without FBS respectively. The cell numbers were counted at 24 h, 48 h, 72 h,96 h, 120 h, and 144 h, then platting and growth curve were drafted. Cell counting kite-8 was used to detect the influence of 5 drugs with different concentrations on human glioma cell line BT325. Results DDP and VM26 significantly suppressed BT325 cells(>75%) viability in a dose-dependent manner, while VCR inhibited BT325 cells (50%) growth without dose-effect relationship. In contrast, ACNU and TMZwere not effective on the viability of BT325 cells. Conclusion BT325 cells were very sensitive to chemotherapeutic drugs DDP amd VM26.

Twenty-nine antagonistic bacillus strains, isolated from some Chinese traditional medicine and fermented food , inhibit the growth of Fusarium oxysporum f. sp. Vasinfectum and Verticillium dahliae Kleb. And twelve of them are able to produce antagonistic proteins. Among the twelve strains, five (H110, H184, H216, B316 and B382) showed higher antibacterial activity. Furthermore, H110 and H184 were identified as Bacillus subtilis, and H216, B316 and B382 as Bacillus licheniformis based on physiological and biochemistry experiments. The antagonistic proteins of five strains were all thermostable, resistant to proteinase K and trypsin, while H184 and H216 partially sensitive to pepsin.

To remedy the limitations of traditional numerical classification softwares,a new application,X-Cluster,was developed by using various design patterns.X-Cluster had powerful functions to support the researching of numerical classification,and testified by some classify studying about Bacillus spp..

Genomic DNA of two fungi Thamnidium elegans and Umbelopsis isabellina were extracted with an amended Cetyltrimethyl Ammonium Bromide (CTAB) method. This modified method uses repeated freezing in liquid nitrogen and thawing with combination of shocking with glass beads to replace of the tra- ditional method. Quality and concentration of DNA extracted by the modified methodwere tested. Compared with the traditional method, higher yield and purity of genomic DNA were obtained with less amount ofmy- celium. The result indicted that this is a simple and highly efficient method, which is suitable to treat many samples at one time and for basic molecular experiments, such as restriction endonuclease reaction and PCR.

Objective To estimate the impact of universal salt iodization on child intelligence quotient (IQ) development in Hainan province. Methods In this is a cross-section study from September in 2008 to April in 2009,the observation group was historical iodine deficiency ward which includes 2 counties and 6 townships,and the control group was non-historical ward which includes 6 counties and 9 townships. Comparison of child IQ distribution according to different geographical housing position(plain,mountainous area,coast),age and sex based on the result of urine iodine examination and the IQ test of children between 8 and 10 years old. Results The median of urinary iodine of children in the observation group was 196.2μg/L which was 2.13 times of the urinary iodine median in the control group(91.9μg/L). The average IQ of children in the observation group was 94.7 which was 8.5 higher than the control group(86.2) ; IQ≤69 rate in this group was 7.7%(91/1179),and it was 8.9 percentage point lower than the control group[16.6%(253/1520)]; IQ≥ 110 rate of the group was 18.3%(216/1179),and it was 10.0 percentage point higher than the control group[8.3%(126/1520)]. The average IQ of children living in mountainous area(83.1) was the lowest in the control group. It was 3.5 and 5.1 lower than that of the children living in the plain(86.6) and coastal area(88.2) respectively; the IQ≤69 rate of children living in mountainous area [20.5%(91/443)]was the highest,and it was 3.8 and 7.1 percentage point higher than that of the children living in the plain [16.7% (89/533)]and coastal areas [13.4% (73/544)]respectively. The average IQ of children aged 8 (97.4) was similar to those aged 9(95.9) in the observation group which was 6.8 and 5.3 higher than that of the children aged 10(90.6) in the same group respectively; However,the average IQ of children aged 8,9 and 10 was close in the control group(86.8,86.3 and 85.6). The average IQ of boys(96.2) was 3.1 higher than that of the girls(93.1),and their IQ≤69 rate[6.3%(37/590)]was 2.9 percentage point lower than that of the girls[9.2% (54/589)]in the observation group. On the other hand,the average IQ(87.2) of boys was 2.1 higher than that of the girls(85.1),and IQ≤69 rate[14.5%(114/787)]was 4.5 percentage point lower than that of the girls [19.0%(139/733)]in the control group. The average IQ of children with different housing geographical position,age and sex in observation group was 5.0-12.4 higher than that of the control group; their IQ≤69 rate was 7.7-13.2 percentage point lower than that of the control group; their IQ≥110 rate was 5.6-13.0 percentage point higher than that of the control group. Conclusions Supplementing salt iodization can improve child intelligence. Supplementing iodine can increase the child IQ and reduce the child mental retardation.
