Multimedia computing technology teaching is a new kind teaching method. It conquers many shortcomings such as poor video, poor expression in traditional teaching of microbiology. But it can also strangle the improvising creation of different teachers in teaching and then lead it to be typical " computer teaching" . So we should obey the teaching discipline in making multimedia computing technology courseware. It can lead many sections part from the class teaching if just emphasize the full use of video and audio. We should make the purpose obviously, and make it as easy as possible in teaching, and we should also explore the fixed regularity to make the teaching and studying integrated perfectly.

Objective To observe the effect of S-adenosyl-L-methionine(SAMe) in treatment of jaundice in newborns and its mechanism.Methods Two hundred and two newborn infants with jaundice were treated with SAMe,76 cases in control group treated with phototherapy and liver enzyme induction elixir;SAMe 30-60 mg/(kg?d) were added to 202 cases intravenously in treatment group.The total biliorubin(T-BILI),direct bilinrubin(D-BILI) and indirect bilinrubin(I-BILI) were dynamically detected.Results Six days after treatment,the skin jaundice index in treatment group decreased remarkably.T-BILI,D-BILI and I-BILI decreased significantly.The curing effectiveness was higher in treatment group than that in control group.The number of applicating blood products and albumin,and blood produets/albumin were decreased in treatment group than those in control group.In those who used glucose to dissolve the SAMe 2.68% had blood-vessel phlebitis.Conclusions SAMe can efficiently quicken the retrogression of jaundice in newborns.It can reduce the use of blood products.It is a reliable and safe drug to treat jaundice in newborns.

OBJECTIVETo study the changes of soil fertility in Sheyang county where Chrysanthemum morifolium has been cultivated for more than 30 years and to develop the special fertilizer for cultivation of C. morifolium.

METHODThe pH values, organic matter and the contents of total and available N, P, K and Zn in the soil layer of 0 to 40 cm, as well as the total N, P, K and Zn contents in the flowers, roots, stems and leaves of the plants, were analysed. The balanced fertilization plan for cultivation of C. morifolium was put forward. In addition, the formula of special fertilizer for cultivation of C. morifolium was determined according to flower yield and utilization rate of N, P, and K.

RESULTS AND CONCLUSIONThe soil had high pH values and high soil salt contents, with unbalanced application of N, P, and K fertilizers and a shortage of available Zn after cultivation of C. morifolium. The contents of soil organic carbon, N and P declined with increasing cultivation time of C. morifolium, which resulted from the improper rotations and fertilization. The balance fertilization practice and the special fertilizer utilization are effective ways to improve soil fertility for C. morifolium.

Objective To construct the Neisseria surface protein A (NspA) DNA vaccine of Neisseria gonorrhoeae and evaluate the humoral and cellular immune responses induced by this vaccine in mice model.Methods The recombinant expression vector pcDNA3.1 (+)/NspA was constructed by inserting NspA gene into the eukaryotic expression vector pcDNA3.1 (+) and confirmed by poly merase chain reaction (PCR),restriction enzymes HindⅢ,XbaⅠand DNA sequencing.NspA mR- NA in transfected RAW264.7 cells and NspA protein expression in transfected COS-7 cells were de- tected by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical stai- ning,respectively.Forty-five male BALB/c mice were immunized with pcDNA3.1 (+)/NspA recom binant plasmid.The level of serum anti-Neisseria gonorrhoeae antibody of the immunized mice was detected by tube agglutination test,and the level of interieron (IFN)-?was assayed by enzyme-linked immunosorbent assay (ELISA).The proliferation of splenocytes was determined by methyl thiazolyl tetrazolium (MTT) colormetry.The NspA gene in BALB/c mice was identified by PCR with the total DNA extracted from quadriceps femoris in immunized sites.Results Restriction enzymes digestion a- nalysis and DNA sequencing results revealed that the pcDNA3.1 (+)/NspA had been constructed successfully.NspA gene had been transcripted and expressed in mammalian cells.The peak titer of specific antibody was 1:640 in pcDNA3.1(+)/NspA immunized group and there was no specific an- tibody detected in both pcDNA3.1 (+) immunized group and PBS group.The IFN-?level in pcD NA3.1 (+) immunized group was (23.79?11.85)pg/mL and that in pcDNA3.1 (+)/NspA immu- nized group was(169.71?30.52)pg/mL (P

Objective To investigate the association of IL-10,IFN-γ gene polymorphisms at position-1082G/A and + 874A/T and susceptibility to pulmonary tuberculosis(PTB)through a case-control study.Methods Polymerase chain reaction with sequence specific primer(PCR-SSP)/sequencing method,single nucleotide polymorphisms(SNP)of IL-10 and IFN-γ gene at position-1082 and +874 were used on pulmonary tuberculosis patients(group PTB)and normal healthy subjects(group NHS)in the Han population from Shenzhen city of China.Results The genotype frequencies of A/A homozygotes,A/G heterozygous and G/G homozygous at-1082 site of IL-10 gene in patients with pulmonary tuberculosis were 85.4%,13.1%,1.5% respectively and A,G allele frequencies were 91.9%,8.1% respectively.In healthy subjects,the genotype frequencies of A/A homozygotes,A/G heterozygous and G/G homozygous were 77.5%,22.0%,0.5% respectively and A,G allele frequencies were 88.5%,11.5% respectively.Genotype distribution between the two groups was significantly different(P＜0.05).The genotype frequencies of A/A of IL-10 in the patient group were higher than that of control group.In contrast,the genotype frequencies of G/A in the control group were higher than that in the patient group(P＜0.05).There was no statistical difference found between A and G allele(P＞0.05).For IFN-γ(+874)and no significant difference was found on the distribution of genotypes or alleles between the two groups.Conclusion The IL-10(-1082)gene SNP might be associated with the susceptibility to tuberculosis.A/A genotype might be a risk factor for the susceptibility on tuberculosis while the SNP of cytokines(+874)might not be associated with the susceptibility to tuberculosis in Chinese Han populations.
