Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

Background Experimental autoimmune uveoretinitis(EAU)is proved to be an organ-specific,T lymphocyte-mediated autoimmune and self-limited disease.Research showed that CD4+CD25+T cell may play important regulation on the course of events,but its mechanism is pending for further study. Objective Present study was to investigate the potential role of CD4+CD25+T cell in the pathogenesis of EAU. Methods Retinal Santigen(S-Ag)was isolated from bovine retinas according tO the procedure as Caspi's previously describe.0.1 ml Santigen(50μg)emulsified with complete Freund'S adjuvant was injected on footpad of 24 inbred adult female Lewis rats aged six to eight-week-old to induce EAU,and 4 normal Lewis rats were as normal control group.Slim-lamp examination was performed to observe the ocular manifestation.Retinal section was prepared in 7,12,15,21 days aher injection for the pathological examination.The pathological grading was on the lnoki'S method.The retinas,inguinal nodes and spleens of rats were obtained in 7,12,15,21 days after injection and the cellular suspension was prepared.Expression of CD4+CD25+T cells on cellular suspension was assayed using flow eytometry.This study complied with the Standard of Association for Research in Vision and Ophthalmology. ResuRs The obvious inflammatory response of the anterior segment was found in S-Ag injected eyes from 7 days through 21 days.The most serious inflammation was found in 12-15 days under the slim-lamp.The hemotoxylin and eosin staining showed the higher pathological grading from 12 to 15 days after injection,showing significant difference in comparison with 7 days and 14 days(P=0.000).In EAU model rats,expressions of CD4+CD25+T cells was significantly increased in retinas, inguinal nodes and spleens in 15 days after injection,showing evidently differences in comparison with control rats(P=0.000). Conclusion The expression level of CD4+CD25+T cells in inflammatory tissue is associated with the inflammation procedure in EAU model rats.This study indicates that CD4+CD25+T cells may play a role in the development of EAU.

A total of 1 473 workers from a natural gas field were selected as the research subjects ， using convenient sampling method. Job Satisfaction Questionnaire Psychological Capital Questionnaire and Social Support ， Results Scale were used to investigate the scores of job satisfaction psychological capital and social support level. The ， ， detection rates of job satisfaction psychological capital and social support in the high level group were 55.9% 52.5% and ， 48.1% respectively. The detection rates of job satisfaction of workers in the high level psychological capital group and high level （ social support group were higher than those in the low level psychological capital group and low level social support group 67.4% vs ， vs ， P ） 43.3% 71.9% 41.2% all <0.01 .

OBJECTIVETo investigate the interference and the mechanisms of Bcl-2 and HER-2 genes antisense oligodeoxynucleotides combined transfection in the human tongue carcinoma Tca8113 cell lines.

METHODSThere were 6 groups in our study, normal control group, Bcl-2 sense experimental group, HER-2 sense experimental group, Bcl-2 antisense experimental group, HER-2 antisense experimental group, Bcl-2 and HER-2 genes antisense oligodeoxynucleotides combined transfection experimental group. In the different times after liposome-mediated transfection, the cell apoptosis, Bcl-2 and HER-2 expressing level were observed by RT-PCR and electronic microscope.

RESULTSAccording to the results of combined transfection experimental group, the apoptosis body and apoptosis cells were observed. The expression of genes were decreased statistically in both Bcl-2 and HER-2, respectively. Bcl-2 and HER-2 combined ASODN was superior to single ASODN in the intervention of tongue carcinoma.

CONCLUSIONBcl-2 and HER-2 ASODN can effectively interfere the expression of HER-2 and Bcl-2 genes. The expression of HER-2 and Bcl-2 can be reduced, and the apoptosis of cells can be enhanced.

OBJECTIVETo investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators.

METHODSThe general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group).

RESULTSThe chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group.

CONCLUSIONElectromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

Objective To evaluate the efficacy and safety of acute ureteroscopy for the treatment of ureterie stones during middle and late pregnancy.Methods From June 1998 to March 2005,17 pregnant women(mean age,27 years;age range,21-35 years)with ureteric stones were treated by ureteroscopy when the fetus was at 20-36 weeks of gestation(mean,29 weeks).All the cases presented with urgent symptoms such as recurrent renal colic(11 cases),fever(4)or acute obstructive anuria(2).Among 17 cases,the stones(between 6 mm?7 mm and 13 mm?21 mm)were located in the upper(8 cases),middle(5)or lower ureter(4);and on the left side(5 eases),on the right(10)and on both(2)of the lower ureter. Mild hydronephrosis were observed in 6 cases and moderate hydronephrosis in 11,Of the 17 cases,14 under- went ureteroscopic pneumatic lithotripsy;in 1 case the calculi were pushed to the renal pelvis;and 2 cases were treated by Double-J catheter drainage.Results All the urgent symptoms in 17 cases were relieved after treatment.The stone-free rate of initial treatment was 82.4%(14 of 17).Three cases with residual stones were treated by Douhle-J catheters,which were replaced every 3 months until the calculi were re- moved.No abortion,premature delivery or complications such as ureter perforation occurred.Mild renal colic occurred in 1 case after insertion of Douhle-J catheter,and it was relieved 3d later;gross hematuria occurred in l case and disappeared 6 d later without treatment.All 17 patients had normal delivery and gave birth to healthy children.Conclusions Ureteroscopy is a safe and reliable method for the treatment of ureteric calculi during middle and late pregnancy.
