To study the effects of 70%Hepatectomy on the proliferation of rat fetal hepatocytes after intrasplenical transplantation, fetal hepatocytes isolated from 3 week SD rat fetuses bred were transplanted into the spleens of liver regeneration model rats with 70% partial hepatectomy. The cell cycle of hepatocytes in the remanent liver was analyzed by flow cytometer and the density dimensions of the donor fetal hepatocytes in spleen were measured by Image Analysis System 7 and 30 days post transplantation respectively. Compared with the control group, the proportions of S state cells in the remanent liver were obviously increased ( P

Polypoidal choroidal vasculopathy(PCV) is a common disease of the retina,the disease is more found in colored race.In China,the mainly nosogenic population is the female about 60 years old.The pathogenesis of PCV is unknown and there is no specific medicine at present.The funduscopic present is orangered lesions,bleed and exudation.Indocyanine green angiography(ICGA) could make a definite diagnosis of PCV.In recent,the main treatment of PCV includes photodynamic therapy,intravitreal anti-VEGF therapy,surgery for treatment of complications and combined therapy.We review the treatment and diagnosis of PCV,and propose the further research direction.
5.Identification and Antimicrobial Resistance Analysis of Mycoplasma from Cervical Secretion
Chinese Journal of Nosocomiology 2006;0(08):-
OBJECTIVE To study infection and drug resistance of Mycoplasma from female genital tract.METHODS Mycoplasma in cervical secretion from inflammed female genital tract were identified by cultivation,and the sensitivities to antibiotics were also performed.RESULTS Mycoplasma were detected in 318 specimens among 588 patients with genital tract inflammation(54.1%),among which Ureaplasma urealyticum(Uu) accounted for 312(98.1%),and Mycoplasma hominis was 6(1.9%).The resistance to 12 kinds of antibiotics indicated that the sensitivities to 8 kinds of antibiotics were higher than 80% and the sensitivities to erythromycin,spiramycin and tetracycline were the lowest.CONCLUSIONS The infectious rates of Uu are on big rise in female genital tract with inflammation and the resistant strains increase continuously.

This paper investigated contamination situation of Listeria monocytogenes(Lm). To compare dif- ferent selectivity enrichment broth for detectable effect of Lm and compare detectable effect in different samples by using different methods, furthermore, choose the best enrichment broth for specific food. One hundred and thirty five random samples from raw meat, aquatic product, fruit and vegetable, quick-frozen food in Baoding. Applied LB enrichment broth, EB enrichment broth, new modification FDA enrichment broth and Fraser enrichment broth before separated by PALCAM selective agar, then identified by interna- tional standard method after PCR. Results: Four methods showed that there were 23 Lm positive, detected 5 Lm by LB method, 6 Lm by Fraser method, 5 Lm by EB method and 7 Lm by new modification FDA method. The total detectable rate of four methods had no large specificity, but to specific kind of food was different.

The antioxidant activity of lycopene is highest among the current carotenoids.Recently the researches on lycopene are focused on ingredient of functional foods in the world.The fermentation production of lycopene by Streptomyces rimosus was reported first time in China.The determination methods,such as spectrophotometric method and HPLC were constructed.Using a stain Fc of Streptomyces rimosus as a original strain,a high-yield lycopene producing mutant strain Fc' was selected after UV mutation.The lycopene yield of the strain is 2.5 times higher than the original strain Fc.The optimal fermentation conditions were determined by flask experiments,and the lycopene yield of strain Fc' reached 230mg/L in flask under the optimal fermentation condition,meanwhile the Streptomyces rimosus strain could produce purer lycopene without adding any blocking agents in its fermentation process.This results lay a good foundation for lycopene commercial production by fermentation using Streptomyces rimosus.

Objective To explore the proportional changes of regulatory B lymphocyte cells (Bregs) and suppressor T lymphocyte cell (Ts) in the peripheral blood of patients with Hashimotos' thyroiditis (HT).Method Sixty-one cases of HT and 38 healthy subjects with matched age and gender were recruited.Flow cytometry technology was used to detect the proportional changes of CD19+ CD24+ CD27 + B cells,CD19+ CD24hi CD38hi B cells,CD19+ IL-10+B cells,and CD8+CD28-T cells.Result Compared with control group,CD19+CD24+CD27+B cells in HT group increased significantly(P<0.05).With the increase of thyroid peroxidase antibody,CD19+ CD24hi CD38hi B cells were decreased significantly.With the increase of antithyrogloblin antibody (TGAb),CD8 + CD28-T cells were decreased markedly (P<0.05).TT3 was positively related with CD19 + CD24hi CD38 hiB cells while TT4 had a negative correlation with CD8+ CD28-T cells and positive correlation with CD19+ CD24+ CD27+ B cells.Logistic regression analysis showed that TGAb and FT4 were independent risk factors for decreased CD8+ CD28-T cells in lymphocyte percentage(P<0.05).TSH was an independent risk factor for the decreased proportion of CD19+ CD24hi CD38hiB cell.FT4 was the independent risk factors for increased CD19+CD24+CD27+B cells(P<0.05).Conclusion The percentage of Ts cells in patients with HT was lowered,while the different phenotypic Bregs cells showed various changes.Thyroid autoantibodies and thyroid function were closely associated with the immunological changes in HT patients.

Objective To design a checklist (NICU-PoHC) for postoperative handover in the NICU (Neurosurgery Intensive Care Unit) in case of information omissions or task errors during the handover process,thus to improve patient safety.Methods Team discussion and literature review was conducted to compose the preliminary version of the NICU-PoHC.Then two rounds of panel review were conducted using the Delphi methods to revise the preliminary checklist and to calculate its Content Validity Index (CVI).Results The authority coefficient of experts was 0.86.Twenty experts proposed 7 suggestions for revision.The NICU-PoHC was developed,and its CVI was 0.88.Conclusions Our study developed the NICU-PoHC,which can be used as an assistant tool guiding the postoperative handover,preventing information omissions and task errors,and thus improving patient safety.
